[0003] Although the above-mentioned device enables quick installation and removal of the switch through a snap-fit ​​structure, in actual use, the installation location of the thermal aerosol fire extinguishing device varies. For example, it can be installed in a wiring cabinet, and for different models of wiring cabinets, the installation angle of the device may be different, resulting in different locations of the trigger switch. This can cause the switch orientation to be unsuitable for the wiring habits of the wiring personnel, affecting the efficiency of switch installation. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated start-up trigger for a thermal aerosol fire extinguishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dedicated start trigger for a thermal aerosol fire extinguishing device includes a flange installed on the adjacent surfaces of the fire extinguishing device housing and end cap, wherein a C-shaped plate is detachably connected to the side surface of the flange.

[0007] The outer surface of the C-shaped plate is nested with a triggering mechanism, and the inside of the fire extinguishing device housing is embedded with an electric detonator.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the utility model, a special starting trigger for a thermal aerosol fire extinguishing device includes a flange 103 installed on the adjacent surfaces of the fire extinguishing device housing 1 and end cap 102, and a C-shaped plate 5 is detachably connected to the side surface of the flange 103.

[0025] The outer surface of the C-shaped plate 5 is nested and slidably connected with a triggering mechanism 4. The inside of the fire extinguishing device housing 1 is embedded with an electric detonator 301. The triggering mechanism 4 is used to electrically connect with an external signal transmission wire and activate the electric detonator 301. A second wire 601 is embedded in one side of the trigger switch 401, and a first wire 6 is embedded in the other side of the trigger switch 401. The second wire 601 and the electric detonator 301 are electrically connected.

[0026] Specifically, when using it, such as Figure 1 As shown, both the end cap 102 and the circular surface of the fire extinguishing device housing 1 are provided with through holes 101 for the spraying of aerosols to extinguish the fire. The lower surfaces of the fire extinguishing device housing 1 and the end cap 102 are fixedly connected to the mounting base 2. The upper surface of the mounting base 2 is provided with mounting holes 201, which can be used to install the device into the electrical cabinet or other cabinets with external threaded parts. The first wire 6 is electrically connected to the external fire detection device. The second wire 601 transmits an electrical signal to the trigger switch 401. The trigger switch 401, in conjunction with the second wire 601, activates the electric detonator 301. The electric detonator 301 detonates the agent cylinders 3 at both ends, causing the oxidant and reducing agent inside the agent cylinders 3 to come into contact and generate aerosols. The trigger switch 401 can slide along the C-shaped plate 5 to change the position of the trigger switch 401, improving the flexibility of the trigger switch 401 during disassembly and assembly. At the same time, the trigger switch 401 can also store excess second wire 601 or first wire 6.

[0027] Example 1

[0028] like Figure 1-4 As shown, the triggering mechanism 4 includes a trigger switch 401, a cavity 403, and a first partition plate 405. The trigger switch 401 is slidably connected to the outer surface of the C-shaped plate 5. A groove 402 is provided on the lower surface of the trigger switch 401. The cavity 403 is located inside the trigger switch 401. A blocking plate 404 is nested at the end opening of the cavity 403. Bolts are threaded onto the outer surface of the blocking plate 404. The blocking plate 404 is detachably connected to the trigger switch 401 via bolts. The first partition plate 405 is fixedly connected to the outer surface of the blocking plate 404. The trigger switch 401 is slidably connected to the C-shaped plate 5 via the groove 402. The C-shaped plate 5 is detachably connected to the flange 103 via a threaded assembly.

[0029] In this embodiment, the flange 103 and the C-shaped plate 5 are used in conjunction with external threaded parts to fix the fire extinguishing device housing 1 and end cap 102. At the same time, the flange 103 and the C-shaped plate 5 form a slide rail for the trigger switch 401 to slide. After the fire extinguishing device housing 1 is installed in the electrical cabinet through the mounting base 2, wiring is required. However, electrical cabinets come in various models, which may result in different installation angles of the device. This may cause the position of the trigger switch 401 to be unsuitable for the wiring habits of the wiring personnel. In this case, the trigger switch 401 can be manually slid so that the trigger switch 401 is facing the wiring personnel or at a certain angle to the wiring personnel, which can be adapted to the wiring habits of the wiring personnel. The same applies to disconnection. After disconnection, sliding the trigger switch 401 will allow the trigger switch 401 to slide out from the opening of the C-shaped plate 5 without disassembling the fixing components, saving the time required for device disassembly and assembly.

[0030] Example 2

[0031] Based on Example 1, in order to address the issue of storing excess wire length in Example 1.

[0032] like Figure 1-4 As shown, an inner rod 406 is fixedly connected to the outer surface of the blocking plate 404 near the cavity 403. A second partition plate 407 is nested and movably connected to the outer surface of the inner rod 406. A spring 408 is nested and connected to the outer surface of the inner rod 406. The second partition plate 407 and the cavity 403 are slidably connected, and the second partition plate 407 matches the first partition plate 405. One end of the spring 408 is in contact with the second partition plate 407.

[0033] In this embodiment, for excess wires, the operator can wind the excess wires around the first partition 405. Under the elastic force of the spring 408, the second partition 407 applies a force to the first partition 405. Based on this, the second partition 407 can cooperate with the first partition 405 to clamp the excess wires, making the device look simpler.

[0034] like Figure 1-4 As shown, a plate sleeve 409 is nested and slidably connected to the outer surface of the inner rod 406. The other end of the spring 408 is in contact with the plate sleeve 409, and the end of the plate sleeve 409 penetrates the cavity 403 and contacts the C-shaped plate 5.

[0035] In this embodiment, under the elastic force of the spring 408, the plate sleeve 409 moves away from the second partition 407, so that the end of the plate sleeve 409 contacts the C-shaped plate 5, increasing the friction between the trigger switch 401 and the C-shaped plate 5, thereby fixing the trigger switch 401. Therefore, in order to slide the trigger switch 401 more smoothly, the plate sleeve 409 needs to be moved manually along the compression direction of the spring 408. The cavity 403 and the inner rod 406 are used to guide the movement of the plate sleeve 409 and the second partition 407.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
