Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerosol fire extinguishing, in particular to a hot aerosol fire extinguishing device. Background Art
[0002] The hot aerosol fire extinguishing device is produced by a high-efficiency aerosol gas-generating agent and a new fire extinguishing composition. The high-efficiency gas-generating agent produces a large amount of inert gas through the redox reaction, and the effective fire extinguishing substance produced by itself and the high-efficiency fire extinguishing medium produced by the thermal decomposition of the new fire extinguishing composition are ejected from the nozzle together. The fire extinguishing composition acts as a chemical coolant due to its own sublimation, thermal decomposition, or endothermic chemical reaction. Compared with traditional pressure-stored fire extinguishers (such as dry powder, carbon dioxide, etc.), portable aerosol fire extinguishers do not require pressure storage, thus saving annual inspection and maintenance costs, and there are no corresponding safety hazards. At the same time, the product has many advantages that other traditional types of fire extinguishers cannot achieve, such as small size, less residue after fire extinguishing, green and environmental protection, easy operation, and reliable performance.
[0003] Existing hot aerosol fire extinguishing devices, such as Chinese patent number CN202020048739.0, discloses a hot aerosol fire extinguishing device, including an outer jacket and an iron can, the inner wall of the iron can is fixedly connected to a flame retardant rubber sleeve, the bottom of the inner wall of the flame retardant rubber sleeve is fixedly connected to a medicine cake, the interior of the flame retardant rubber sleeve is evenly filled with aerosol particles, the iron can is fixedly connected to the interior of the outer jacket, the top of the iron can and the top of the outer jacket are at the same horizontal plane, the top of the outer jacket is fixedly connected to an upper cover, the top of the upper cover is circular and has four rows of air holes at equal distances from the center of the upper cover, the central thread of the top of the upper cover is connected to a through-hole screw, the inside of the through-hole screw is fixedly plugged with a silicone fiberglass tube, and the center of the inside of the silicone fiberglass tube is fixedly connected with a thermal wire; the utility model replaces the traditional manual opening method by providing a thermal wire and a medicine cake, so that the device can be automatically and quickly started according to environmental changes, thereby effectively improving the fire extinguishing efficiency of the device.
[0004] However, the above solution still has defects. The aerosol particles are energized by thermal wires and medicine cakes, which requires certain requirements for the dryness of the thermal wires and medicine cakes. However, in a relatively humid environment, the dryness of the thermal wires and medicine cakes cannot be guaranteed, and there is a situation where the thermal wires or medicine cakes do not burn, causing the hot aerosol fire extinguishing device to lose its fire extinguishing function. In addition, the air vents are directly exposed to the outside, and dust can easily enter the air vents, making it difficult to clean the dust, which brings a bad user experience.

The arrangement of the magnet 150 between the outer sleeve 110 and the tin can 120 makes the tin can 120 more firmly fixed in the outer sleeve 110. In addition, it is also convenient to install the tin can 120 on a magnetic object. A first air vent 160 is provided on the flame retardant rubber sleeve 130. The first air vent 160 is arranged in multiple rows, and the multiple rows of first air vents 160 are axially equidistantly arranged on the flame retardant rubber sleeve 130. The desiccant 140 is evenly filled in the flame retardant rubber sleeve 130, and the medicine cake 195 is fixed on the bottom of the inner wall of the tin can 120.
[0027] Example 2: A preferred embodiment of the present invention provides a hot aerosol fire extinguishing device, which differs from the above embodiment only in that:
[0028] Aerosol particles 197 are evenly filled in the flame-retardant rubber sleeve 130, and the upper cover 170 is fixed on the upper surface of the outer sleeve 110. It also includes a positioning column 198, one end of the positioning column 198 is fixed on the outer wall of the upper cover 170, and the positioning column 198 is inserted in the outer sleeve 110. The setting of the positioning column 198 facilitates the rapid assembly of the upper cover 170 to the outer sleeve 110. It also includes a screw 196, and the upper cover 170 and the outer sleeve 110 are fixed together by the screw 196. The through-hole screw 190 threadedly passes through the upper cover 170.
[0029] Example 3: A preferred embodiment of the present invention provides a hot aerosol fire extinguishing device, which differs from the above embodiments only in that:
[0030] It also includes a nut 191, which is threaded onto the through-hole screw 190. The setting of the nut 191 facilitates fixing the through-hole screw 190 on the upper cover 170. The lower end of the silicone fiberglass tube 193 is fixed in the through-hole screw 190, the thermistor 194 is fixed in the silicone fiberglass tube 193, and the lower end of the thermistor 194 is inserted into the medicine cake 195. The film 192 is fixed on the upper surface of the upper cover 170, and the through-hole screw 190 passes through the film 192. A second air vent 180 is provided on the upper cover 170, and a plurality of second air vents 180 are provided, and the plurality of second air vents 180 are evenly distributed on the upper cover 170.
[0031] Working principle: During use, when a fire breaks out externally, the heat-sensitive wire 194 is ignited. At this time, the medicine on the medicine cake 195 is ignited by the heat-sensitive wire 194. The medicine cake 195 burns and generates heat, heating the aerosol particles 197 inside the iron can 120. The aerosol particles 197 are decomposed by heat to produce a large amount of gas. The gas breaks the film 192, and the gas is ejected to the outside through the second air vent 180, which has the effect of extinguishing the fire. The setting of the desiccant 140 in the flame-retardant rubber sleeve 130 can ensure the dryness of the heat-sensitive wire 194, aerosol particles 197 and medicine cake 195. The setting of the film 192 effectively prevents dust from entering the second air vent 180, and because the film 192 is flat, it is easy to clean the dust on it. The hot aerosol fire extinguishing device uses the desiccant 140 and the first air vent 160 to ensure the dryness of the heat-sensitive wire 194 and the medicine cake 195. In addition, the setting of the film 192 facilitates the cleaning of dust, giving users a better user experience.
[0032] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
