Description
- The field of the invention is candle snuffers.
- Candles have been used for thousands of years, and for much of that time people have used candle snuffers to extinguish the flames. In some instances candle snuffers have included sophisticated functions, including for example U.S. Pat. No. 1,941,082 to Benziger (December 1933) and U.S. Pat. No. 5,344,309 to Phare (September 1994). The Benziger patent teaches a candle snuffer having a bulb that can be squeezed to provide a puff of air used in extinguishing the flame. Phare contemplates using gas from a CO2 cartridge to extinguish the flame.
- These and all other extraneous materials discussed herein are incorporated by reference in their entirety. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
- One aspect that was not addressed by Benziger and Phare was reduction in smoke emitted by the snuffed out candle wick. That issue was squarely addressed by U.S. Pat. No. 6,267,581 to Harrison (July 2001), which teaches extinguishing a candle by subjecting the flame to a water mist. The '581 device was apparently not commercially successful, however, presumably because users don't necessarily want water on their candles or surrounding objects, and also because the mist doesn't necessarily work very well in eliminating smoke.
- Thus, there is still a need for a candle snuffer that reduces or even eliminates smoke from extinguishing candles.
- The present invention provides apparatus, systems and methods in which a candle snuffer has a handle and head, and a suction mechanism that pulls a gas from the head and through a filter.
- The snuffer head can comprise any suitable material(s), but in preferred embodiments comprises a non-flammable ceramic material or a metal. Snuffer heads can advantageously be painted or otherwise decorated, and in especially preferred embodiments snuffer heads can be detachable and interchangeable.
- The suction mechanism and filter can be placed in any suitable location relative to head, but are preferably placed within the handle. Although not strictly necessary, the snuffer head and the handle can be coupled by a gas conduit of a suitable length, preferably between about 5 to 10 cm long. The conduit could alternatively be much longer, as for example in a candle extinguisher embodiment for snuffing candles in chandeliers, or atop shelving. Unless the context clearly indicates otherwise, all ranges set forth herein should be interpreted as including their endpoints.
- The suction mechanism is preferably motorized, and preferably has a rather small operating capacity. Thus, in especially preferred embodiments, the suction mechanism has an operating capacity of no more than 8000 cm3 per minute, and emits a noise of less than 70 db during normal operation.
- The filter can be upstream or downstream of the motor, and preferably filters out particles down to 5 μm in size.
- Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawings in which like numerals represent like components.
-
FIG. 1 is a vertical cross-section of a preferred candle snuffer. -
FIG. 2 is a side view of a metal preferred snuffer head, showing an opening for coupling to the gas conduit and handle. -
FIG. 3 is a side view of a ceramic snuffer head, showing painted decoration. - In
FIG. 1 , acandle snuffer 100 generally comprises asnuffer head 110, agas conduit 120 and ahandle 130. - Snuffer
head 110 is shown here as having a typical frustoconical shape and size, which in this case has a base that measures about 3 cm wide and about 4-5 cm tall. Those skilled in the art will of course appreciate that other shapes and sizes would also work, including full cones, shapes with oval or rectangular, hexagonal or other horizontal cross-sections. - As best seen in
FIG. 2 ,snuffer head 110 has arim 114 that defines an opening for receiving an end of thegas conduit 120. In this instance, coupling between thehead 110 and theconduit 120 is accomplished by a snap fitting, and is orientation specific by virtue of thegas conduit 120 having aprojection 122 that mates with acutout 112 in thehead 110. All manner of other couplings are also considered, including for example a simple screw fitting in which therim 114 andgas conduit 120 have mating threads (not shown). - Snuffer
head 110 can include any suitable material or materials, including especially metals (including alloys), ceramics, and composites. Of particular interest are snuffer heads having painted, etched or other decorations. Snufferhead 300 inFIG. 3 has adecorative design 316 which should be interpreted euphemistically as all possible designs. -
Gas conduit 120 is preferably about 5 to 10 cm long, but could also measure up to a meter or even longer, as for example in a candle extinguisher embodiment for snuffing candles in chandeliers, or atop shelving. At the other extreme, the head and the handle could juxtapose one another, and in that instance the gas conduit would simply be the opening between head and the handle. Contemplated gas conduits can be made from any suitable material(s), including once again metal(s), ceramic(s), and/or composite(s). -
Handle 130 generally includesdownstream extensions gas conduit 120,batteries suction mechanism 136, afilter 138, and aswitch 139. Each of these components can be conventional, and their cooperation to achieve the purposes of the device is well within the skill of the art given the teachings herein. Thus,housing 130 includes electric wiring (not shown) that couples thebatteries switch 139 and thesuction mechanism 136. -
Suction mechanism 136 includes amotor 136A and afan 136B. Motor 136 A is preferably a low capacity motor, sufficient to provide sufficient suction capacity, but low enough to reduce noise, battery drain and cost. To that end preferred motors cooperate with thefan 136B to pull no more than 8000 cm3 of air per minute, and emits a noise of less than 70 db during normal operation. These limitations are not, of course, strictly necessary to practice the inventive subject matter, and for example motors are contemplated that pull ≦2000, ≦4000, ≦12,000, and ≦24,000 cm of air per minute. Similarly, motors are contemplated that emits noises of ≦30, ≦50, ≦80, ≦90 db. Still further, to facilitate long battery, and user convenience,switch 139 can advantageously include a timer that automatically shuts down power to the motor after a given time period, such as ≦5, ≦7, ≦10. or ≦20 seconds. -
Filter 138 is preferably a HEPA filter, but in any event is sufficient to filter out at least 50%, more preferably at least 80%, and most preferably at least 95% of the mass of smoke particles encountered by the filter at some point in the life of the filter. In especially preferred embodiments thefilter 138 can filter out particles having a diameter of ≦5 microns (μm), more preferably particles with diameters of ≦3 μm, and most preferably particles with diameters of ≦2 μm. - Those skilled in the art should also appreciate that each of the elements shown herein is representative of all components that would satisfy the requirements. Thus,
batteries suction mechanism 136 could be replaced by other mechanisms (e.g. a bellows) that do not involve a fan. Those skilled in the art should also appreciate that various components can be user replaceable. Thus, thebatteries filter 138 should all be considered as user replaceable, even though the Drawing does not expressly depict doors or other mechanisms for users to access and replace those components. - It should also be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
