The purpose of the present invention, its function and principle will be further elucidated in the detailed description with reference to the accompanying drawings.

Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1 and 2, the present embodiment provides a hot aerosol automatic fire extinguishing apparatus 100, which comprises an upper shell 10 and a lower shell 20, wherein the lower shell 20 is provided with a reaction zone 21, a cooling zone 22 and a buffer zone 23, a bracket 211 for placing a solid grain is arranged in the reaction zone 21, and the solid grain is suitable for releasing high-temperature aerosol fire extinguishing agent after being heated. The cooling region 22 is communicated with the reaction region 21 through an inlet channel 221, and is communicated with the buffer region 23 through an outlet channel 222. The side wall of the lower shell 20 is also provided with a plurality of spraying openings 24, and the aerosol fire extinguishing agent is suitable for being sprayed outwards through the spraying openings 24 to extinguish flame.

The solid grain is a solid medicament which can rapidly generate aerosol fire extinguishing agent after being burnt or heated, and the medicament is commonly used in the component industry and is not detailed in detail.

The upper shell 10 is fixedly connected with the lower shell 20, and a sealed cavity is formed inside the upper shell. Two partition plates (not shown) are correspondingly arranged in the upper shell 10, so that the reaction zone 21, the cooling zone 22 and the buffer zone 23 are relatively isolated and are communicated only through the air inlet channel 221 and the air outlet channel 222, and the high-temperature aerosol fire extinguishing agent is prevented from leaking without being cooled.

Specifically, a cooling device 223 suitable for cooling the aerosol fire extinguishing agent is arranged in the cooling area 22, and the cooling device 223 is preferably a Z-shaped cooling structure and/or a cooling agent bag. The Z-shaped cooling structure means that the airflow channel of the cooling area 22 is Z-shaped, and the temperature of the high-temperature airflow gradually decreases when the high-temperature airflow passes through the long and narrow channel. If the temperature reducing agent is used as an auxiliary material, the temperature reducing effect is better, and the temperature reducing agent bag can be conveniently replaced after the temperature reducing agent is used for a certain number of times, so that the temperature reducing capacity of the cooling area is maintained.

In this embodiment, the bracket 211 comprises a support 2111 for supporting the solid charge and a fixed angle 2112 for limiting the movement of the fixed charge, wherein the bracket 211 is made of metal, ceramic and/or high temperature resin, or other high temperature resistant material, such as PA66 (polyhexamethylene adipamide, commonly referred to as nylon-66). A certain height is provided between the bracket 211 and the bottom surface of the lower case 20 to prevent the lower case 20 from being burned or penetrated by the solid grains when burning.

A groove 25 is further formed on the sidewall of the lower case 20, and a thermal initiator may be embedded in the groove 25, and the thermal initiator is connected to the inside of the solid charge via a hole formed in the groove 25. The thermal initiator of the embodiment can be a thermal wire or other starting devices, when a fire disaster occurs outside, the starting devices such as the thermal wire are ignited by high temperature or flame, the flame reaches the solid grain along the starting devices, and then the solid grain is ignited, so that the fire extinguishing device is started. Therefore, the temperature and the flame of the protected space can be effectively detected, and the effect of quickly extinguishing the fire in case of fire is achieved.

In order to avoid the high-temperature aerosol fire extinguishing agent generated by the solid grain from directly spraying out of the hole, the embodiment is designed that the hole is communicated with the cooling area 22, and the heat-sensitive wire extends to the solid grain through the cooling area 22 and the reaction area 21 in sequence. Thus, the high-temperature aerosol fire extinguishing agent is cooled to a certain temperature by the cooling area 22 and then sprayed out of the hole, and the size of the hole can be reduced as much as possible, so that the high-temperature aerosol fire extinguishing agent can just penetrate through the heat-sensitive wire, and a large amount of aerosol fire extinguishing agent is prevented from being sprayed out of the hole.

In addition, the present embodiment designs the outlet channel 222 as a plurality of slits. Since a large amount of hot aerosol fire extinguishing agent is generated in a short time when the solid grain is burnt, the pressure of the reaction area 21 and the pressure of the cooling area 22 are very high, when the aerosol fire extinguishing agent enters the buffer area 23 from the cooling area 22, the gas pressure passing through the slit is instantly reduced, the aerosol fire extinguishing agent expands and cools, and therefore, the temperature of the aerosol fire extinguishing agent sprayed out of the spraying opening 24 is greatly reduced.

To sum up, the utility model discloses a set up this three independent region of reaction zone, cooling space and buffer for the high temperature aerosol fire extinguishing agent that the reaction zone produced just outwards spouts behind cooling space and buffer, greatly reduced causes the risk of secondary harm. And each area has simple structure, and the areas are communicated through an air inlet channel or an air outlet channel, so that the high-temperature aerosol fire extinguishing agent has better cooling effect.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
