[0002] Aerosol fire extinguishing device: According to the way of generating aerosol, it can be divided into hot aerosol and cold aerosol. Aerosol fire extinguishing devices used in domestic projects are all hot type. Cold aerosol fire extinguishing technology is still in the development stage and there is no formal product. Hot aerosol extinguishes fire based on the principles of negative catalysis and destruction of the combustion reaction chain. Aerosol is different from halogenated hydrocarbons and inert gas halon replacement technologies. Ordinary aerosols have residues after fire extinguishing and are non-clean fire extinguishing agents. The new generation of S-type aerosols have higher cleanliness. Due to the different formulations of agents adopted by various companies, the properties of the residues after spraying some non-clean aerosols are also different.
[0003] Existing aerosol fire extinguishing devices mainly rely on thermal sensing components for activation. The thermal sensing components mainly include triggering media such as thermistors and temperature-sensitive glass balls. The existing thermal wire air pipe joints and fire extinguishing devices are mostly installed and fixed by multiple sets of bolts, which makes the overall assembly of the aerosol fire extinguishing device more complicated, thereby increasing work intensity and reducing work efficiency.

[0029] See also Figure 1-6 ,The utility model provides a technical solution:
[0030] The air pipe joint connected to the thermal line of the aerosol device comprises a fire extinguishing device body 1, an air outlet pipe 2 is fixedly arranged on the outside of the fire extinguishing device body 1, a connecting pipe 3 is movably arranged on the outside of the air outlet pipe 2, a mounting plate 6 is fixedly sleeved on the outside of the connecting pipe 3, a plurality of groups of inner grooves 11 are penetrated through the outside of the mounting plate 6, a fixing cylinder 12 is fixedly arranged on the inside of the plurality of groups of inner grooves 11, a connecting rod 13 is movably inserted on the inside of the fixing cylinder 12, the connecting rod 13 movably penetrates the fixing cylinder 12 and extends to the outside, and the outer side of the connecting rod 13 is fixedly sleeved with a mounting plate 6 ... plurality of groups of inner grooves 11 are penetrated through the fixing cylinder 12 and extend to the outside, and the outer side of the connecting rod 13 is fixedly sleeved with a mounting plate 6, a plurality of groups of inner grooves 11 are penetrated through the fixing cylinder 12 and extend to the outside, and the outer side of the connecting rod 13 is fixedly sleeved with a mounting plate 6, a plurality of groups of inner grooves 11 are penetrated through the fixing cylinder 12 and extend to the outside, and the outer side of the connecting rod 13 is fixedly sleeved with a mounting plate 6, a plurality of groups of inner grooves 1 A mounting plate 15 is fixedly provided on the outer part of the fixing cylinder 12 at the side end, a clamping block 16 is fixedly provided on the outer side of the mounting plate 15, a mounting disc 2 7 is fixedly provided on the outer side of the air outlet pipe 2, a plurality of groups of inner grooves 2 17 are penetrated through the outer side of the mounting disc 2 7, and a clamping groove 18 for docking with the clamping block 16 is provided on the inner side of the plurality of groups of inner grooves 2 17. The traditional bolt fixing method of the connecting pipe 3 and the air outlet pipe 2 is changed to a fixing method of the clamping block to the clamping groove, which can greatly improve the installation efficiency of the connecting pipe 3 and facilitate the subsequent maintenance and replacement.
[0031] Specifically, a temperature-sensitive glass ball 4 is fixedly provided at the outer end of the connecting pipe 3, and a thermistor 5 is coiled on the outer side of the temperature-sensitive glass ball 4. By providing two thermal sensing mechanisms, the temperature-sensitive glass ball 4 and the thermistor 5, the sensitivity of the fire extinguishing device body 1 can be improved. No matter which of the temperature-sensitive glass ball 4 and the thermistor 5 is triggered, the fire extinguishing device body 1 will be activated to extinguish the fire, thereby improving the safety of use.
[0032] Furthermore, the connecting pipe 3 is movably sleeved on the outside of the air outlet pipe 2, a limit block 8 is fixedly arranged on the outside of the mounting plate 1 6, and a limit groove 9 for docking with the limit block 8 is opened on the outside of the mounting plate 2 7. When the mounting plate 1 6 docks with the mounting plate 2 7, the limit block 8 is inserted into the limit groove 9, thereby improving the connection stability between the mounting plate 1 6 and the mounting plate 2 7, thereby ensuring the installation stability of the connecting pipe 3.
[0033] It is worth noting that a sealing gasket 10 is fixedly arranged inside the limiting groove 9. The sealing gasket 10 can improve the connection sealing effect between the air outlet pipe 2 and the connecting pipe 3, thereby ensuring the overall sealing of the device.
[0034] It is worth noting that a spring 14 is provided on the inner side of the fixed cylinder 12, one end of the spring 14 is connected to the inner side of the fixed cylinder 12, and the other end of the spring 14 is connected to the connecting rod 13. The spring 14 does not deform initially. When the movable mounting plate 15 drives the clamping block 16 to move, the connecting rod 13 can stretch the spring 14. At this time, the spring 14 deforms. When the mounting plate 15 is loosened, the elastic potential energy of the spring 14 is released, thereby being able to drive the clamping block 16 to firmly engage in the clamping slot 18, thereby further ensuring the connection stability of the air outlet pipe 2 and the connecting pipe 3.
[0035] In addition, a push block 19 is fixedly provided on the outer side of the mounting plate 15. The push block 19 can be provided to facilitate pushing of the mounting plate 15, thereby improving the convenience of operation.
[0036] It must be said that multiple groups of anti-sliding blocks are arranged on the outside of the push block 19, and the multiple groups of anti-sliding blocks are all made of soft materials. The anti-sliding blocks can increase the friction of the push block 19, making it more convenient to push the push block 19 and avoiding slipping.
[0037] Working principle: First, when assembling the device, push the multiple groups of push blocks 19 outward, and the push blocks 19 drive the connecting rod 13 to move to the outside of the fixed tube 12 and stretch the spring 14. When the push blocks 19 move, they drive the mounting plate 15 and the block 16 to move. Then, the mounting plate 16 is docked with the mounting plate 2 7, so that the limit block 8 is inserted into the limit groove 9 and rests against the sealing gasket 10. Then, release the multiple groups of push blocks 19. At this time, the elastic potential energy of the spring 14 is released, so that the connecting rod 13 can be driven to move and reset into the fixed tube 12. When the connecting rod 13 moves, it drives the mounting plate 15 and the block 16 to move and reset. At this time, the block 16 is inserted into the groove 18 on the inner side of the inner groove 2 17, so that the connecting pipe 3 can be quickly installed.
