Candle extinguisher

Abstract

The present invention relates to a device for extinguishing burning candles, in particular, stearin candles, with the help of a pressurised, non-combustible fluid. The fluid is stored in a compressed, liquid form in fluid cartridges and is released in measured amounts from the device with the help of a device for measured release according to the present invention. The device is particularly suited for extinguishing candles that are difficult to access, and for application of fluid sources with relatively high pressure.

Description

[0001]The present invention relates to devices for extinguishing burning candles with the help of gas. In more detail, the present invention relates to a device for extinguishing burning candles with the help of gas where the device comprises a fluid source with a pressurised fluid, a passage space in which the fluid expands to gas, an appliance for point supply of the gas towards the burning candle and an activation arrangement for the release of the fluid from the fluid source, where the activation arrangement comprises an axially moving piston that is fastened to a sealing body for the opening and closing of the fluid outflow from the fluid source, as the activation arrangement works on the axial piston so that the sealing body lets out fluid to the appliance via the passage space. The present invention also relates to a use of this device.PRIOR ART[0002]Extinguishing burning lights / candle lights can be carried out in different ways. It is most common that one blows out the candl...

Benefits of technology

[0043]The device with a pipe, in particular, a flexible swan neck, has the great advantage in that it makes it simpler to extinguish candles at difficult access locations, particularly in combination with the appliance that gives an efficient, measured, directed release of gas in a concentrated and defined direction.

[0044]The fluid source can be in the form of a cartridge casing with fluid that is set into a cartridge chamber. The candle extinguisher, according to the present invention, preferably uses CO2 in fluid form at high pressure, about 60 bar at room temperature, and is configured so that it is possible to use a replaceable gas cartridge, something which makes recycling of the candle extinguisher possible. The advantage with the gas cartridge is that it increases the user friendliness in that one can exchange the cartridge and also that more gas can be stored in a smaller volume than with the known candle extinguishers of the spray can type. Thereby, the device can be of a much smaller size than known spray can solutions of the same capacity. The device can be adapted to standardised fluid cartridges that are available on the market from before.

[0045]The device according to the invention makes it thereby possible to use gas cartridges with compressed gas in liquid form under high pressure. This is possible through a combination of the described valve solution w

Problems solved by technology

The problem with this extinguishing method is that melted wax/stearin can be sprayed around and also that the glowing wick can be moved or be blown off.

Furthermore, this method is not suitable when the candle light is located at places with difficult access or in narrow containers.

This method has the disadvantage in that it leads to a layer of soot on the equipment and on the candle.

The disadvantage with this known method is that such a spray can must have a certain volume, and thereby size, so that an appropriate amount of gas can be stored to achieve a sufficient capacity.

Furthermore, such a spray can is typically used only once, that means it is thrown away when it is empty and it is not suitable for recycling.

In general, spray cans are thereby an environmental challenge and therefore there is an established recirculation arrangement for spray cans in many industrialised countries to recover valuable materials, such as aluminium, from the spray cans and to minimise the waste problems.

A challenge for the extinguishing itself with many of the known candle extinguishing solutions is that the release of gas is difficult to measure and that relatively large amounts of gas can be released or that the gas flows out under a high pressure.

This can lead to the wick being blown away, for example, in tea lights where the stearin is melted or that melted stearin is blown about.

There is also a potential risk that glowing parts of the wick are blown uncontrollably about with a resulting fire risk.

Another problem, which has not been satisfactorily solved by the known methods, is that stearin candles that are physically difficult to access cannot be reached in an optimal way with such extinguishing devic
