FIELD OF THE INVENTION

The present invention relates to bubble generating toys, and in particular, to a compact size bubble generating machine that generates continuous streams of bubbles in desired directions.

BACKGROUND OF THE INVENTION

Bubble generating machines have many adaptations and uses and are particularly appealing to young children. Many bubble generating machines are already available on the market. For example, FIGS. 1-3 shows a conventional bubble generating machine 100. Specifically, FIG. 1 is a side view, FIG. 2 is a side sectional view, and FIG. 3 is a top sectional view of the same conventional bubble machine.
This bubble generating machine 100 mainly comprises an outer cover or shell 101, a motor 102, a gear box 103, an impeller 104, a wheel 105, and a bubble solution reservoir 106. The shell 101 includes an opening 107 for releasing the bubbles generated by the machine. The motor 102 is positioned between the impeller 104 and the wheel 105, and functions to rotate the impeller 104 to produce airflow in a generally horizontal direction. The motor 102, together with the gear box 103, also functions to rotate the bubble generating wheel 105. The wheel comprises a plurality of rings 108 fixed to the rim of the wheel 105. When rotated, the rings 108 on the wheel 105 are sequentially dipped into the reservoir 106 that holds the bubble producing fluid (such as a dilute soap solution) and then removed therefrom as the wheel 105 continues rotating. The bubble solution forms a thin film or membrane on the rings 108. The impeller 104 blows air horizontally against the film, forming bubbles that are then released via the opening 107. Generally, the rings have stria or teeth, allowing them to hold more fluid and thus make many more bubbles before the fluid needs to be replenished.
However, it is generally undesirable to blow bubbles in the horizontal direction for several reasons. For example, the bubble generating machine is often placed on a horizontal surface during use, but blowing bubbles in a horizontal direction causes a significant numbers of bubbles to burst on the horizontal surface, thus wasting a significant amount of bubble fluid. The burst bubbles also contaminate the surface area surrounding the bubble generating machine as well as the machine itself, necessitating subsequent cleaning of these surfaces. Further, the horizontal airflow results in less air time for each bubble, as each bubble is closer to the ground on release.
Blowing bubbles in a vertical direction is generally not possible with these systems, as the bubble heads must be rotated through a horizontal reservoir of bubble solution and consequently must be orthogonal, or at a right angle, to such bubble solution. Tilting the machine as a whole into an upright direction would generally spill the bubble solution out of the reservoir, thereby eliminating the source of bubble solution for future bubbles from the bubble machine.
Further, the rotation of wheel 105 is generally achieved by engaging the gear box 103 with the teeth located on the outer edge of wheel 105. The rotating plane of wheel 105 is substantially in-line or parallel to the rotating axis of the motor 102. Consequently, the horizontal length of the traditional bubble generating machine needs to be long enough to accommodate the length of the impeller and the motor and gearbox, plus the entire diameter of the wheel 105, making the physical size of the bubble generating machine 100 quite large. Moreover, the airflow produced by the impellor 104 needs to travel from the impellor 104 through the area that accommodates the motor 102 and the gear box 103 before it reaches the wheel 105. The motor 102 and the gear box 103 partially block the airflow produced by the impeller 104. This makes the conventional machine 100 less efficient at producing bubbles.
Therefore, there is a need for a compact size bubble generating machine that automatically generates a continuous stream of bubbles in a substantially vertical direction and in a more efficient way.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The present invention reverses the configuration of the motor and fan and turns the bubble wheel at right angles to significantly reduce the size of the bubble machine. In the prior art machine above, the configuration is fan>motor>wheel, and the plane of the bubble wheel is in-line with the axis or plane of the fan and motor. By putting the wheel at right angles, and/or by reversing the motor and fan configuration (motor>fan>wheel), and/or by sitting the fan wholly or partially inside the wheel, the current invention significantly reduces the footprint of the device.
According to one aspect of the present invention, a compact size bubble generating machine is provided, that comprises a housing having an upper opening; a bubble generator positioned inside the housing and adjacent to the upper opening; an impeller positioned inside the housing; and a motor positioned inside the housing and operatively coupled to the impeller and the bubble generator. In this variation, the actuated motor causes the impeller and the bubble generator to rotate simultaneously. In some embodiments, the impeller is positioned between the bubble generator and the motor. In some other embodiments, the impeller and the bubble generator share a common rotating axis.
According to another aspect of the present invention, the bubble generating machine further comprises an airflow channel extending from the impeller towards the upper opening so as to force the airflow generated by the impeller from a horizontal direction to a substantially vertical direction.
According to a further aspect of the present invention, a compact size bubble generating machine is provided, which comprises a housing having an upper opening; a ring turntable positioned inside the housing and adjacent to the upper opening; a turntable rotator attached to the ring turntable for rotating the ring turntable; a fan positioned inside the housing; an airflow channel extending from the fan towards the upper opening so as to force the airflow generated by the fan from a horizontal direction to a substantially vertical direction; and a motor positioned inside the housing and operatively coupled to the fan and the turntable rotator, wherein the motor, when actuated, causing the fan and the turntable rotator to rotate simultaneously. In some embodiments, the impeller is positioned between the bubble generator and the motor. In some other embodiments, the impeller and the bubble generator share a common rotating axis.
According to another aspect of the present invention, the turntable rotator preferably rotates the ring turntable via friction force.
The following detailed description and the accompanying drawings further illustrate certain embodiments of the current invention.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The following detailed description is directed to various embodiments of the invention. It is made for the purpose of illustrating different embodiments of the invention, and should not be taken as limitations to the current invention. The scope of the invention is best defined by the appended claims. In certain instances, detailed descriptions of well-known devices and mechanisms are omitted so as to not obscure the description of the present invention with unnecessary detail.
FIGS. 4-6 illustrate the exterior appearance of a bubble generating machine 200 according to one aspect of the present invention. Specifically, FIG. 4 is a top view of a bubble generating machine 200 according to a preferred embodiment of the present invention. FIG. 5 is a side view and FIG. 6 is a bottom view of the bubble generating machine 200 of FIG. 4. As shown in FIG. 4-6, the machine 200 has a housing that comprises of a top surface 201, a side surface 202 and a bottom surface 203. The surfaces can be in a cubic or hemispherical shape, or any other desired shape. The various surfaces are connected together by, for example, screws or welding or glue, or alternatively the shell can be integral. These surfaces 201, 202 and 203 together define a hollow interior for housing and protecting the internal components of the machine 200, as described below.
Referring to FIGS. 4 and 5, in some embodiments of the invention, there is an opening 204 in the top surface 201, through which the rings can be seen and the bubbles released. Alternatively, the opening 204 can be positioned on a top portion of a side surface 202. In some other embodiments, the opening 204 is positioned at a top corner of the bubble generating machine 200, i.e. at the juncture of the top surface 201 and the side surface 202 or on an upper end of a side surface 202. In this way, bubbles will be blown out directly from the air channel below and will be propelled in a direction that is substantially away from the horizontal surface.
By “substantially away from the horizontal surface” what is meant herein is that the bubbles are emitted from an angle that is at least 10 degrees in reference to the horizontal surface. In a preferred embodiment, the bubbles are propelled vertically, e.g., about 90 degrees plus or minus 45 degrees, from the horizontal surface, as this is the most desired direction and allow the bubbles to stay in the air for the longest time before they reach the ground. In the most preferred embodiment, the bubble are essentially vertically (about 90 degrees) propelled.
As people in the art can readily perceive, other variations of the location of the opening 204 can also be used in the bubble generating machine 200. As long as the bubbles are blown from a substantially vertical direction away from the horizontal surface as shown in the conventional bubble generating machine 100 of FIGS. 1-3, the bubble generating machine should be considered as not departing from the teaching of the present invention.
In some embodiments of the invention, there is a port 206 in the side surface 202 for adding bubble solution to the reservoir (not shown in FIGS. 4-6) located at the bottom of the housing. In other embodiments, the reservoir is separate and is inserted into the housing from a side opening which may be closable if desired. In other embodiments of the invention, the reservoir is defined by the bottom surface 203 and a lower part of the side surface 202. In yet some other embodiments of the invention, the housing also has an air inlet 207 (as shown in FIG. 7) which, in combination with the top opening 204, forms a complete path of the airflow driven by the impeller in the housing.
Referring to FIG. 6, the housing has a bottom cover 205 in the bottom surface 203. The bottom cover 205 seals the power source (not shown in FIGS. 4-6) for providing power to the motor in the housing. In some embodiments of the invention, the bottom cover 205 is attached to the housing with a screw. The power source is a set of batteries in some embodiments.
In another embodiment of the invention, an on/off switch 208 is provided on the housing and preferably on the side surface 202 (as shown in FIG. 8). The switch 208, in combination with other necessary electronic circuits, is operatively coupled to the power source for providing power to the motor in the housing. The necessary electronic circuits are common knowledge in the related arts, description of which is therefore omitted herein for simplicity.
FIGS. 9-11 illustrate the internal structures of a bubble generating machine 300 according to some embodiments of the present invention. Specifically, FIG. 9 is a top sectional view of a bubble generating machine 300 according to a preferred embodiment of the present invention. FIG. 10 is a side sectional view and FIG. 11 is a rear sectional view of the bubble generating machine 300 of FIG. 9.
Referring to FIG. 9, the bubble generating machine 300 comprises a housing 301, a ring turntable 302, an impeller or fan 303, a motor 304, a gear box 305, and an airflow channel 306. As shown in FIG. 9, the housing 301 accommodates the other components of the bubble generator 300 and bubble solution in the reservoir of the housing 301 (not visible in FIG. 9).
The ring turntable 302 consists of a series of rings 309 positioned in a circular direction. We have shown the rings as toothed or serrated annular forms, but any shape can be used, so long as it will hold some amount of fluid and create a membrane through which bubbles can be blown. Further, the rings 309 can be of the same shape and diameter and, more preferably, in different diameters so as to produce bubbles of different sizes. When the ring turntable 302 rotates, the rings 309 on the turntable sequentially dip into the bubble solution to form solution films, and then sequentially pass through the opening of the airflow channel 306 to generate bubbles. The bubbles are released to the air through the top opening 307 of the housing 301 in a substantially vertical direction due to the fact that the air channel 306 forces air into a vertical flow.
As shown in FIG. 9, the impeller 303 may have a plurality of blades that are spaced apart around a hub. The impeller 303 is operatively coupled to the motor 304. When the motor 304 is actuated, the impeller 303 is driven by the motor 304 to rotate, producing substantially horizontal airflow to the air channel 306. In one embodiment of the invention, the impeller 303 is a fan.
To propel the impeller 303 and the ring turntable 302, a motor is included in the bubble generating machine 300. Preferably, only one motor 304 is used in the entire bubble generating machine, which will be discussed in more detail below. However, people skilled in the art would appreciate that more than one motor can be used to achieve the same effects as described herein.
In some embodiments, the motor 304 is operatively coupled to the impeller 303 on one side and to a gear box 305 on the other side, which in turn operates the ring turntable 302 via structures to be discussed below. The motor 304 functions as the main source of generating motion to rotate the impellor 303 and the ring turntable 302. In one embodiment, the motor 304 is further electrically coupled to a power source via a switch and other necessary circuits. By operating the switch, the motor can be turned on/off.
Preferably, the gear box 305 consists of a set of gears for rotating the ring turntable 302. In some embodiments, the gear box 305 is coupled to the motor 304 on one side and to the ring turntable 302 on the other side. A main shaft 308 can be used to connect the motor 305 and the gear box. The set of gears in the gear box 305 can be configured in such a manner that, when the motor 304 is actuated, the gear box 305 will rotate the ring turntable 302 at a rotating velocity that is slower than that of the impeller 303. This particular arrangement can allow the motor 304 to serve two functions: 1) it rotates at a higher speed for rotating the impeller 303 and thus generating enough airflow to form bubbles; 2) it turns the gear box 305, which in turn, rotates the ring turntable 302, at a lower speed to allow the rings to slowly move through the airflow, thus allowing bubbles to form when the air blows through the rings 309. In some embodiments, the lower rotating speed is achieved by varying the gear ratio of the different gears inside the gear box 305. Other structures/arrangements can be used to achieve the same function as people skilled in the art can readily perceive, which will not be further elaborated herein for simplicity.
In some embodiments, an airflow channel 306 is positioned between the impeller 303 and the rings 309 that rotates toward the opening 307. In other words, the air flow channel 306 sits just beyond the impeller 303, and inside the turntable 302, thus accepting air from the impeller 303 and re-directing it into an upwards flow by virtue of its shape and top opening (not seen in FIG. 9, but see opening 407 in FIG. 12, wherein opening 407 of the air channel 306/406 at least partially overlaps with opening 307 to ensure that air is efficiently blown out from opening 307).
Depending on the location of the opening 307 on the surface of the bubble generating machine, the airflow channel 306 can be of various shapes. For example, when the opening 307 is positioned on the top surface of the bubble generating machine, the airflow channel can be an L shaped channel that directs the airflow generated by the impellor 303 from a horizontal direction to a substantially vertical direction toward the opening 307. In other embodiments, when the opening 307 is position at another portion of the bubble machine's surfaces, different shaped airflow channels can be used. The only requirement is that the airflow channel contain and redirect the airflow towards the opening in the exterior housing (thus the airflow channel opening and the housing opening largely overlap).
The air flow channel 306 can be cylindrical. Alternatively, the shape of the airflow channel 306 can be adapted to suit the contour of the impeller 303 motion. In yet another embodiment of the invention, the inner diameter of the airflow channel 306 is larger than that of of the ring turntable 302. The airflow guided by the airflow channel 306 finally blows against the rings 309 of the ring turntable 302 and pushes the bubbles through the top opening 307 to the outside.
In contrast to the conventional bubble generating machine 100 as shown in FIGS. 1-3, the bubble generating machine 300 of the present invention has a more compact structure. As shown in FIGS. 9-10, in one embodiment of the current invention, the ring turntable 302 rotates in a plane that is substantially vertical to the common rotating axis I-I′ of motor 304. Stated in another way, the motor 304, the impeller 303, and the ring turntable 302 in the preferred embodiment all share a common rotating axis I-I′. Such “common axis” structure make the bubble generating machine 300 more compact than the conventional bubble generating machine 100 as shown in FIG. 1, because the length of the bubble machine now accommodates the thickness of the ring turntable 302, not the diameter of the ring turntable 302. Thus, the size of the bubble generating machine 300 can be greatly reduced.
To further reduce the size of the bubble generating machine 300, certain portions of the turntable 302, impeller 303 and/or motor 304 can overlap with one another in terms of their spatial locations. For example, as shown in FIG. 9, impeller 303 is positioned partially inside the circular space defined by the ring turntable 302. Other arrangements are also possible.
It should be noted that variations to the above described common rotating axis I-I′ can also be used without departing from the teaching of the current invention. For example, the motor 304 may have a rotating axis I-I′ (not shown), the impeller 303 may have a different rotating axis A-A′ (not shown), the ring turntable 302 may have another rotating axis B-B′ (not shown). The 3 axes are offset from each other and meanwhile remain substantially parallel to each other. In some other examples, angles of about 5 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, and so on may exist between any two of the axes. The offset(s) and angle(s) can be achieved by using different gear box arrangement and/or rotating shaft(s) connecting the motor 304, the impeller 303, and the ring turntable 302. As a person skilled in the art will understand, the above “substantially parallel” variations are also within the “common axis” limitations as defined in the appended claims.
Refer to FIG. 12 for a more detailed illustration of the “common axis” structure depicted in FIGS. 9-11. FIG. 12 is an exploded view of the bubble generating machine 400 according to a preferred embodiment of the present invention. According to FIG. 12, the airflow channel 406, the impellor 403, the motor 404, the gear box 405, and the ring turntable 402 of FIG. 12 correspond to the airflow channel 306, the impellor 303, the motor 304, the gear box 305, and the ring turntable 302 of FIGS. 9-11 respectively. In a preferred embodiment of the present invention, the bubble generating machine 400 further comprises a connecting junction 4010 and a turntable rotator 4011.
The connecting junction 4010 is positioned between the airflow channel 406 and the turntable rotator 4011, and consists of a housing 4012 that holds the motor 404. As shown in FIGS. 9-12, according to one embodiment of the invention, the motor 404 has a shaft 308 connecting to the gear box 405, which has an output gear that connects to an inline gear (not shown in the Figure) of the turntable rotator 4011. When the motor 404 is actuated, the motor 404 will finally rotate the turntable rotator 4011 through the output gear of the gear box 405 and the inline gear of the turntable rotator 4011.
According to one embodiment of this invention, the connection between the connecting junction 4010 and the airflow channel 406 is by screws or other means to fix the connecting junction 4010 to the air flow channel 406. On the other hand, the connecting junction 4010 is not physically connected to the turntable rotator 4011. They are actually two separate parts adjacent to each other.
In a preferred embodiment, the turntable rotator 4011 is not fixed to the ring turntable 402. Instead, it is positioned closely adjacent to the ring turntable 402 so that the rotation of the turntable rotator 4011 will force and turn the ring turntable 402 attached to it via friction force. According to one embodiment of this invention as shown in FIG. 13, the turntable rotator 4011 comprises a connecting rim 4013 in annular shape, that matches well with the inner rim 4014 of the ring turntable 402, i.e., closely opposed to each other. When the turntable rotator 4011 is rotated by the motor 404, the connecting rim 4013 of the turntable rotator 4011 will exert friction force on the inner rim 4014 of the ring turntable 402, and cause the ring turntable 402 to rotate accordingly.
In comparison with the traditional structure that the motor is fixed to the ring turntable 406, either directly or via a gear box/turntable rotator, the novel “attaching” structure of the present invention functions as a safety mechanism. For example, when a person such as a child accidentally puts a finger or a pencil into the bubble blower hole, the ring turntable 402 will stop rotating. If the turntable rotator 4011 were fixed to the ring turntable 402, the turntable 402 would not be easily stopped, which may cause injuries to the child. Also, if the turntable 402 were forced to stop, it would in turn force the gear box 405 and the motor 404 to stop, which could cause overheating to the motor 404 and/or stripping of the gears. In the above “attaching” design, such problem is avoid as the turntable rotator 4011 is only attached to the ring turntable 402 via friction and therefore, if the ring turntable 402 is being stopped accidentally, the turntable rotator 4011 can rotate by itself and thus prevent injuries to the operator and/or overheating to the motor 404.
When the various components in FIG. 12 are assembled together, the gear box 405, the motor 404 and a portion of the connection junction 4010 are located within the cylindrical hollow portion of the turntable rotator 4011. The air channel 406 together with another portion of the connection junction 4010 forms a winding drum for guiding the airflow generated by the impeller 403.
The novel bubble generating machine of the present invention has several advantages over the conventional bubble generating machine as shown in FIGS. 1-3. First, as described above, the bubble generating machine according to one embodiment of the present invention has a reduced size because the motor, the impeller and the ring turntable share a common, or substantially common, rotating axis. Second, unlike the conventional bubble generating machine, the impeller of the bubble generating machine of the invention is positioned between the ring turntable and the motor. Thus the airflow generated by the impeller directly blows against the blower turntable, whereas the motor of the conventional bubble generating machine will block some of the airflow generated by the impeller. The more sufficient usage of the airflow in the present invention will increase the productivity of the bubbles generated. Moreover, the efficient use of the airflow makes it possible to use smaller impeller, smaller winding drum and smaller motor, which further reduces the size of the bubble generating machine.
Further, a compact size bubble generating machine (e.g., bubble generating machine 300) of the present invention provides can simultaneously actuate the rotation of the air generator (e.g., impeller 303) and the bubble generator (e.g., ring turntable 302) at different rotating velocities. Also, with the air channel 306 or 406, the bubble generating machine of the present invention can produce bubbles in a substantially vertical direction, thus giving longer bubble air time. Additionally, according to one embodiment of the present invention, the structure of the bubble generating machine that the turntable rotator is attached but not fixed to the ring turntable provides a safety mechanism that prevents the motor from overheating when the ring turntable is forcibly stopped.
While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. For example, the air channel and the connection junction may be combined together to be a single components and a separate container containing bubble solution may be placed in or attached to the bubble generating machine instead of the self-reservoir formed by the housing of the bubble generating machine. The accompanying claims best describe the scope of the present invention.
