Description

Technical Field

[0001] This utility model relates to the field of aerosol fire extinguisher technology, and in particular to a detachable aerosol fire extinguishing device. Background Technology

[0002] Aerosol fire extinguishers are a new type of fire extinguishing device that uses chemical and physical methods to release extinguishing agents in an aerosol state to extinguish fires. Their working principle involves releasing fine aerosol particles to cover the fire source and block oxygen, thus quickly extinguishing the fire. These particles can rapidly diffuse in high-temperature environments, forming a dense fire-extinguishing cloud that effectively inhibits the spread of flames. Specifically, the aerosol fire extinguisher combines a highly efficient gas-generating agent with a fire-extinguishing particle generator. Under the thermal and dynamic action of the extinguishing gas produced by the agent, the fire-extinguishing particle generator decomposes and releases highly efficient fire-extinguishing particles, thereby achieving the fire-extinguishing effect.

[0003] Most existing aerosol fire extinguishers are integrated designs, with the aerosol generator inside the tank. The bottom of the tank is electrically connected to the activation mechanism located below via a wire. Since both are integrated inside the tank, if the activation mechanism malfunctions, the aerosol fire extinguisher cannot be activated and used properly, making it impossible to disassemble, repair, or replace it, resulting in unnecessary waste.

[0004] Therefore, it is necessary to invent a detachable aerosol fire extinguishing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a detachable aerosol fire extinguishing device. It features a nozzle with a mounting ring fixedly connected to its bottom, which is threaded onto the inner side of the outer casing. A coolant layer is located on the outer side of the aerosol canister, and this coolant layer can be extracted from the top of the casing. The bottom of the aerosol canister has a trigger base and a first connector, which are electrically connected to a second connector below via a wire and plug, thus connecting to a connecting block. This facilitates the removal of the aerosol canister from the inside of the casing, enabling convenient disassembly. This addresses the problem mentioned in the background art where existing aerosol fire extinguishers are mostly integrated designs, with the aerosol generator directly placed inside the canister and its bottom electrically connected to the triggering mechanism below via a wire. Since both are integrated inside the canister, a malfunction in the triggering mechanism prevents the aerosol fire extinguisher from being properly activated, hindering disassembly, repair, or replacement, resulting in unnecessary waste.

[0026] like Figures 1-3 As shown, a detachable aerosol fire extinguishing device disclosed herein may include an outer shell 1, a coolant layer 4 disposed on the inner side of the outer shell 1, and an aerosol canister 22 disposed on the inner side of the coolant layer 4.

[0027] The top of the aerosol can 22 is fixedly connected to a mounting ring 21, and the top of the mounting ring 21 is fixedly connected to a nozzle 2. The mounting ring 21 is threaded to the inside of the outer shell 1.

[0028] A fixing block 11 is fixedly connected to the bottom of the outer casing 1. A connecting block 6 is provided at the bottom of the fixing block 11. A threaded ring 64 is fixedly connected to the top of the connecting block 6. The threaded ring 64 is threadedly connected to the inner side of the fixing block 11.

[0029] Therefore, by setting the nozzle 2, the bottom end of the nozzle 2 is fixedly connected to the mounting ring 21, which can be threaded to the inside of the outer shell 1. The outer side of the aerosol can 22 is provided with a coolant layer 4, which can be pulled out from the top of the outer shell 1. The bottom end of the aerosol can 22 is provided with a trigger base 23 and a first plug terminal 231, which is electrically connected to the second plug terminal 65 below through the wire 5 and the plug 51, thereby electrically connecting with the connecting block 6, so as to facilitate the removal of the aerosol can 22 from the inside of the outer shell 1 and facilitate disassembly.

[0030] like Figure 3 As shown, in a preferred embodiment, the bottom end of the connecting block 6 is fixedly connected to an excitation mechanism 62, a pressing block 63 is provided on one side of the excitation mechanism 62, and a slot 61 is provided on the outer side of the connecting block 6.

[0031] Therefore, the internal structure of the ignition mechanism 62 mainly consists of a spring, a hammer, and a piezoelectric ceramic below. Its working principle is that when the pressing block 63 is pressed, the internal spring is compressed. When the pressure of the spring reaches the critical value, it will drive the hammer to strike the piezoelectric ceramic below. This violent impact will cause the piezoelectric ceramic to generate a voltage spark instantly. The ignition mechanism 62 is electrically connected to the first plug-in terminal 231 above through the second plug-in terminal 65, which facilitates the ignition function.

[0032] like Figure 3 As shown in this disclosure, a protective sleeve 3 is provided on the outer side of the connecting block 6, and a retaining ring 31 is provided on the inner side of the protective sleeve 3. The retaining ring 31 is located on the inner side of the retaining groove 61.

[0033] Therefore, by setting the protective sleeve 3, the protective sleeve 3 can effectively protect the pressing block 63 and avoid accidental contact. By setting the retaining ring 31, the retaining ring 31 can be engaged with the inner side of the retaining groove 61, thereby facilitating the setting of the protective sleeve 3 on the outer side of the connecting block 6.

[0034] like Figure 3 As shown, in a preferred embodiment, a trigger base 23 is fixedly connected to the bottom of the aerosol can 22. Two first plug terminals 231 are symmetrically arranged at the bottom of the trigger base 23, and a plug 51 is inserted into the inner side of the first plug terminal 231.

[0035] Therefore, by setting a trigger base 23, which is fixedly connected to the bottom of the aerosol can 22, to trigger the aerosol inside the aerosol can 22 to be sprayed out, it is a well-known technical solution in the art. The electric spark generated in the connecting block 6 below is conducted along the wire 5 to the first plug end 231 and the trigger base 23 for ignition, which facilitates the spraying of the aerosol inside the aerosol can 22.

[0036] like Figure 3 As shown in this disclosure, the top two sides of the connecting block 6 are symmetrically fixedly connected with second plug terminals 65, and the inner side of the second plug terminal 65 is also connected with a plug 51, and the outer side of the plug 51 is provided with a wire 5.

[0037] Therefore, by symmetrically fixing a second plug terminal 65 to the top of the connecting block 6, a plug 51 is also plugged into the inner side of the second plug terminal 65, and a wire 5 is provided on the outer side of the plug 51. The other end of the wire 5 is electrically connected to the plug 51 provided at the bottom of the trigger base 23, and the plug 51 can be easily pulled out from the inner side of the first plug terminal 231 and the second plug terminal 65 respectively, which facilitates disassembly and maintenance and easy reinstallation.

[0038] In practical use, the protective cover 3 can be removed from the outside of the connecting block 6, and the pressing block 63 can be pressed. The internal spring will be compressed. When the pressure of the spring reaches the critical value, it will drive the hammer to strike the piezoelectric ceramic below. This violent impact will cause the piezoelectric ceramic to generate a voltage spark instantly. The ignition mechanism 62 is electrically connected to the first plug 231 set above through the second plug 65, which facilitates the ignition function. The second plug 65, wire 5, plug 51 and first plug 231 lead to the trigger base 23, which facilitates the activation of the trigger base 23 to start the nozzle 2 to start the spraying operation.

[0039] When disassembly is required, the rotating excitation mechanism 62 can drive the connecting block 6 to rotate, and finally unscrew the threaded ring 64 from the inside of the fixing block 11. At this time, the second plug end 65 and the plug 51 are disassembled, making it easy to remove the plug 51 from the second plug end 65.

[0040] Rotate the nozzle 2 to unscrew the mounting ring 21 from the inside of the housing 1, and then remove the aerosol can 22 from the inside of the housing 1. This makes it easy to maintain or replace the internal components.

[0041] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
