Description

Field of the invention

The invention relates to an air-pressure shock candle and wick flame extinguisher.

State of the art

Candles and other wicking flames are generally extinguished by blowing out.

Are known extinguishers; which consist of a bell and suffocate the flame or wax molds that extinguish the candle.

Also, lids are known which are preferably placed over tealight holders to choke the flame.

• Das Ausblasen mit dem Mund hat Grenzen durch Entfernungen und dadurch notwendige ungünstige Körperhaltungen und Aufstellung der Kerzen oder Öllampen.

The weaknesses of the above methods are:

• Blowing with the mouth has limits through distances and thus necessary unfavorable postures and placement of candles or oil lamps.

The bells are not suitable for tealights
The cover plates are only suitable for tealights in containers and limited because of the variety of containers.

The wax moldings are time-consuming to handle, not up to date and not suitable for all applications (unfavorable installation of candles).

All these systems have one drawback in common: they do not take into account the fact that the new lighters (also with a flexible rod) have made candle locations possible that are not or not easily reachable with conventional lighters.

The US-A-225350 shows a candle extinguisher, comprising an elongated base body with integrated cylinder, in which an air pressure surge is generated with a piston or a piston unit, wherein the piston is tensioned with an actuating lever and triggered.
The US-A-3870105 shows a flame extinguisher, for example, for extinguishing candle flames, with a cylindrical container in the form of a syringe, in which a fire-extinguishing medium, such as a fire extinguishing powder is included. By actuating a piston, the fire extinguishing powder can be blown out of the container onto the flame.
The US-A-5344309 discloses a combined candle lighter and candle extinguisher, wherein the candle extinguisher comprises a gas cylinder for extinguishing the candle flame. The DE 3906148 A1 describes a candle extinguisher that works with nitrogen gas that is in a gas cartridge.

Disclosure of the invention

It is the object of the invention to provide a device for extinguishing candles or wick flames, which allows a simple and safe extinguishing of wick flames.

This object is achieved by a device having the features of claim 1.

Preferred embodiments and further advantageous features of the invention are specified in the dependent claims, the contents of which are referred to here.

With the invention of the air-pressure shock candle and wick flame extinguisher, it is possible to avoid all the aforementioned disadvantages and to extinguish the candles and other wick flames at all locations with a finger movement, which wax splashes are avoided because of the rapid pressure surge, because the wax to thick.

Description of preferred embodiments of the invention FIG. 1

shows the candle extinguisher consisting of an elongated ergonomically shaped handpiece -1- with an integrated cylinder -16-, in which an air pressure surge by means of a piston -2- also with piston ring -3-, -303-, is generated. The piston -2- is movably arranged in the cylinder -16- and comprises a piston rod -8- which is guided in the handpiece -1-.

The cylinder -16- opens on one side in a preferably conical nozzle, which may also be formed as an annular nozzle -4- or Siebdüse -20-.
In the initial position, the piston -2- is at the front, the nozzle-facing end of the cylinder -16-. The piston -2- is clamped against a spring -10- by means of a piston -2-fixedly arranged, axially magnetized -magnets -5- and a Eisenrückholers - 6-. The spring -10- sits on a guide pin. The iron returner -6- is retracted by an operating lever -11-. The magnet -5- adheres to the iron returner -6- which carries the magnet -5- and the associated piston -2- The iron returner 6 may also consist of a ring 17 which is placed on a non-magnetic molding.

During clamping of the piston -2- this is moved together with the piston rod - 8- to the right in the direction of the handle portion of the handpiece -1-. In the handle part of the handpiece -1- an adjustable stop -9- is arranged, on which the piston rod abuts -8-. As a result, the magnet -5- is suddenly released from the iron-repeater -6- and thrown by the spring -7-. The air in the cylinder -16- is compressed by the piston -2- abruptly, whereby a pressure surge at the nozzle -14- emerges. The iron retractor -6- is automatically pushed forward again into its starting position by another spring -7- and re-engages the magnet -5- so that the process can be repeated. The device therefore works with a repeating function.

The operating lever -11-, runs in a slot -12- in the cylinder and is operated like a pistol.

By means of the adjustable stop -9- it is possible to set the triggering time and thus the performance of the candle extinguisher to the individual requirements.

By bending the nozzle -14- a comfortable handling of tealights is possible. The possible uses are also by angled extensions -15- straight angled, curved or flexible, completed.

A rubber ring -13- and / or a spring -19-, -319- dampens the piston -2- in the end position during the stop. The spring -19- also ensures that the piston -2- is pushed back slightly, so that the magnet sits earlier at the retractor, resulting in a shortening of the operating lever.

The optional ring nozzle -4- or screen nozzle -20- compresses the outflowing air and increases the performance and the accuracy by the thereby possible larger diameter of the nozzle.

FIG. 2

In this embodiment, a diametrically poled magnet -101- is inserted and moved axially inside the tube by means of an iron ring slide -102- sliding on the outside of the tube.
On the slide ring is the operating lever -103-.
The return spring -104- acts directly outside via the piston tube.
The axial guidance is achieved by a tongue and groove system -105-.
The ring slider -102- and the return spring -104- can work under a cover -106-.

FIG. 3

In this version, the return spring -201- acts separately, with the ram -202-attached to the ring slider -102-.

FIG. 4

It is one opposite FIG. 1 modified embodiment of the invention shown. Regarding FIG. 1 are the same components or components with the same function denoted by the same reference numerals, unless otherwise stated. For each reference character is compared to FIG. 1 the number 300 added.

In this version, the operating mechanism is integrated in the handpiece -301- (housing). The puller is designed as a finger opening -311- in the housing -301-. By pulling back the puller -311- with the finger, the iron retractor - 306- is moved. The magnet -305- is taken along by iron-repeater -306-. As a result, the piston unit 308, consisting of the piston rod 302, the piston ring 303, the magnet 305, the damping ring 350, is tensioned against the spring 307-. In this case, a release cam -351- arranged on the piston rod 302 abuts against a bulkhead -352- which is fixedly arranged in the handpiece 301. The Auskösenocken is formed for example by flattening on the piston rod 302 This causes the magnet -305- abruptly replaced by the Eisenrückholer -306- and can the piston unit 308 by the force of the spring -310- shoot in a cylinder -316- after. The air in the cylinder -316- is compressed, thereby generating an air pressure surge exiting the nozzle 314. The damping spring 319 is conical, so that it can be compressed to a wire thickness. This results in a travel extension of the piston unit 308 and increases the pressure performance.

The nozzle -314- can be infinitely angularly adjusted by axial rotation -314-. The stop -353- prevents the puller -311- from retracting too far after release.
