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.

AI Technical Summary

Benefits of technology

The device described in this patent text utilizes an activating arrangement to release fluid from a piston. This arrangement includes a lever arm to transfer force from an activating body to the piston. The device also includes a sealing body that is fastened to one end of the piston and at least partially surrounded by a fixed extended casing. This activating arrangement makes it easier to release the fluid outflow, even when using high-pressure sources. The device is designed to minimize fluid expansion during activation, which helps to control the amount of fluid expansion and temperature, reducing the likelihood of freezing and discomfort for the user. The device also allows for efficient regulation of gas pressure and amount released through the puncturing needle diameter and the passage space between the piston / shaft and casing / chamber.

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 devices.

A challenge is also stearin candles that are placed in locations with difficult access, such as high up on shelves, in window frames, or stearin candles on Christmas trees and so on.

The extinguishing of such lights can lead to one burning oneself, or that one simply will have to struggle to reach them at all, both when they shall be extinguished with the help of the known devices or when they shall be extinguished by using one's breath.

It is generally a challenge, particularly with devices for extinguishing candles with the help of a gas, which operate with a low pressure of a non-combustible gas, that they have a limited reach.

Then, such candle extinguishers will not reach stearin candles at locations which are difficult to access.

Furthermore, with devices that use higher gas pressures, known problems occur, namely that the pressure is often too high when the devices shall also be used for shorter distances, which really requires smaller pressures for the extinguishing.

This leads in turn to the problems described above, namely that both the wick can be moved in tea lights when the stearin is melted, that melted stearin can be blown about and / or that glowing parts of the wick can be dispersed.

The lack of possibilities to release measured amounts of gas with respect to the distance to the candle that shall be smothered makes it generally difficult for the user to optimally apply the known candle extinguishers.

Another problem that arises with the application of devices with a high pressure of fluids such as CO2, is that the moving parts in the valve can freeze because of the loss of heat when a fluid goes over from the fluid expansion state in the container to the gaseous state outside it.
