Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire extinguishing device capable of preventing mis-starting. Background Art

[0002] The starting structure of a thermal aerosol fire extinguishing device usually adopts a thermistor wire or an electronic ignition head as the starting structure. When the thermistor wire is used as the starting structure, no external electronic equipment is required. When the temperature reaches the preset value, the thermistor wire senses the temperature to start the fire extinguishing device, which is very reliable. However, some chemical substances in the thermistor wire are currently controlled substances, and from an environmental protection perspective, thermistor wire has a certain destructiveness to the environment. When the electronic ignition head is used as the starting structure, it has almost no pollution to the environment and can be connected to an external detection and alarm system to achieve linkage with the fire protection system. However, when the fire extinguishing device adopts an electronic ignition head as the starting structure, the static electricity carried by the human body and the static electricity generated externally during the assembly and installation or transportation of the fire extinguishing device may cause the fire extinguishing device to start incorrectly once it comes into contact with the starting wire of the electronic ignition head.

[0003] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Utility Model Content

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0023] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] In order to solve the technical problem that the conventional fire extinguishing device using an electronic ignition head as a starting structure is easily affected by static electricity and causes the fire extinguishing device to be started incorrectly, this embodiment provides a fire extinguishing device that prevents incorrect start-up, such as Figure 1-Figure 2 As shown, it includes: a shell 1, an electronic ignition head 2 and a wiring part 3. The shell 1 is preferably cylindrical with external patterns for easy handling. The upper part of the shell 1 is provided with a nozzle 11, and the lower part of the shell 1 is provided with a bottom cover 12. The shell 1 is filled with a coolant 4 and an aerosol generator 5. The coolant 4 is filled in the upper part of the shell 1, and the aerosol generator 5 is filled in the lower part of the shell 1. The electronic ignition head 2 is arranged between the coolant 4 and the aerosol generator 5. The electronic ignition head 2 is used to ignite the aerosol generator 5, and the wiring part 3 is fixed to the bottom cover 12. The wiring part 3 has an anti-misstart function. In this embodiment, by providing a wiring part 3 with an anti-misstart function, it is possible to effectively prevent the electronic ignition head from being mistriggered due to static electricity, thereby causing the fire extinguishing device to misstart.

[0025] In some optional implementations, the wiring portion 3 includes a fixed end 31 and a rotating end 32 that are movably connected. Specifically, the fixed end 31 and the rotating end 32 are connected in a rotatable and movable manner; wherein the fixed end 31 is fixedly connected to the bottom cover 12; the starting line 21 of the electronic ignition head 2 is connected to the contact portion 6 of the fixed end 31 and the rotating end 32; a short-circuit wire 7 and a docking wire 8 are provided inside the rotating end 32; the docking wire 8 is connected to the starting line 21 of the electronic ignition head 2 and extends to the outside of the shell 1; wherein, when the rotating end 32 rotates, the short-circuit wire 7 can be connected to the contact portion 6 of the fixed end 31 and the rotating end 32 to achieve connection with the starting line 21 of the electronic ignition head 2. Through the short-circuit wire 7, the starting line 21 of the electronic ignition head 2 can be in a short-circuit state, and the static electricity is consumed. Therefore, the electronic ignition head 2 will not be triggered by mistake. When it is necessary to extinguish the fire, the rotating end 32 is rotated to a preset angle to release the short-circuit condition between the short-circuit wire 7 and the starting line 21 of the electronic ignition head 2.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
