Description

TECHNICAL FIELD

[0001] The utility model relates to fire fighting equipment technical field, especially in a kind of aerosol fire extinguishing device with sealing mechanism. BACKGROUND

[0002] Aerosol fire extinguishing agent can quickly and effectively extinguish various types of fires, and has good fire extinguishing effect on class A, class B and class C fires. Its principle is to make the internal fire extinguishing agent produce a large number of aerosol particles through chemical reaction. These aerosol particles can quickly spread in the fire scene and inhibit the combustion reaction through physical and chemical action.

[0003] After searching, the utility model patent with publication number CN222445235U discloses an aerosol fire extinguishing device with a sealing mechanism. By setting a rotating ring and a rotating ring base, the device can be quickly activated even if the on-site personnel are in an emotional breakdown and nervous state. The operation process of the device is more simple and convenient, reducing the response time in emergency situations. In addition, the aluminum film at the top of the aerosol fire extinguisher body can prevent dust or impurities from entering the aerosol nozzle, ensuring that the spraying effect of the aerosol nozzle reaches the ideal effect during subsequent fire extinguishing operations.

[0004] Although the above-mentioned aerosol fire extinguishing device can use the aluminum film at the top of the aerosol fire extinguisher body to protect and seal the aerosol nozzle, preventing dust or impurities from entering the aerosol nozzle, it can only be used once. After the aluminum film is broken, the entire fire extinguishing device will be discarded, resulting in high use cost.

[0005] Therefore, it is necessary to invent an aerosol fire extinguishing device with a sealing mechanism to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0026] Figure 1 is a schematic diagram of the overall structure of an aerosol fire extinguishing device with a sealing mechanism according to an embodiment of the present disclosure.

[0027] Figure 2 is a schematic diagram of the structure of a handheld aerosol fire extinguisher 1 of an aerosol fire extinguishing device with a sealing mechanism according to an embodiment of the present disclosure.

[0028] Figure 3 is a schematic diagram of the structure of a detachable cover mechanism 2 and a sealing mechanism 3 of an aerosol fire extinguishing device with a sealing mechanism according to an embodiment of the present disclosure.

[0029] As shown in Figures 1-3 , the aerosol fire extinguishing device with a sealing mechanism of the present disclosure can include components such as a handheld aerosol fire extinguisher 1, a detachable cover mechanism 2, and a sealing mechanism 3.

[0030] As shown in Figure 2 , in the present disclosure, the handheld aerosol fire extinguisher 1 is provided with an aerosol nozzle at the top, and a switch on the front.

[0031] It should be further noted that the handheld aerosol fire extinguisher 1 is a commercially available existing product, and thus its specific structure and model are not described in detail.

[0032] As shown in Figure 3As shown, in a preferred embodiment, the detachable sleeve mechanism 2 comprises a sleeve tube 21 sleeved outside the handheld aerosol fire extinguisher 1, a rubber pad 22 is arranged at the bottom inside the sleeve tube 21, a plurality of anti-skid grooves for increasing friction are uniformly arranged inside the rubber pad 22, the rubber pad 22 is fixed to the outside of the handheld aerosol fire extinguisher 1 by friction, and a cover plate 23 is fixedly arranged at the top end of the sleeve tube 21, and a fire extinguishing agent output opening 24 is arranged at the center of the top of the cover plate 23.

[0033] Thus, after the completion of fire extinguishing, one hand holds the handheld aerosol fire extinguisher 1 and the other hand holds the sleeve tube 21, and the sleeve tube 21 is pulled off from the outside of the handheld aerosol fire extinguisher 1 and a new handheld aerosol fire extinguisher 1 is inserted into the inside of the sleeve tube 21, which can be reused compared with the prior art.

[0034] As shown, Figure 3 In the present disclosure, the sealing mechanism 3 comprises a limiting sliding groove 31 arranged at the top right side of the sleeve tube 21, a guide rod 32 is fixedly arranged inside the limiting sliding groove 31, a return spring 33 and an auxiliary handle 34 are sequentially sleeved and arranged outside the guide rod 32 from top to bottom, the auxiliary handle 34 is slidingly arranged inside the limiting sliding groove 31 and is slidingly connected with the guide rod 32 in the vertical direction, a sealing pressure plate 35 is fixedly arranged at the inner end of the auxiliary handle 34, a sealing pad 36 for sealing the fire extinguishing agent output opening 24 is adhesively arranged at the top of the sealing pressure plate 35, a sealing baffle 37 for sealing the limiting sliding groove 31 is fixedly sleeved and arranged outside the auxiliary handle 34, and a handle sleeve 38 is fixedly sleeved and arranged at the end of the auxiliary handle 34 away from the sealing pressure plate 35.

[0035] Thus, when fire extinguishing operation is needed, first, the safety pull ring at the bottom of the handheld aerosol fire extinguisher 1 is pulled off, then one hand holds the handheld aerosol fire extinguisher 1 and the other hand holds the handle sleeve 38 outside the auxiliary handle 34 and pulls it backward, at this time, the auxiliary handle 34 slides inside the limiting sliding groove 31 along the guide rod 32 and compresses the return spring 33, at the same time, the sealing pad 36 is driven by the sealing pressure plate 35 to remove the blockage of the fire extinguishing agent output opening 24, thereby removing the sealing, then the switch on the surface of the handheld aerosol fire extinguisher 1 is pressed by the hand holding the handheld aerosol fire extinguisher 1, at this time, the aerosol fire extinguishing agent is sprayed from the aerosol nozzle at the top of the handheld aerosol fire extinguisher 1, then it is sprayed from the fire extinguishing agent output opening 24 to the fire source under the guidance of the inner wall of the sleeve tube 21 for fire extinguishing, during the fire extinguishing process, since one hand holds the handheld aerosol fire extinguisher 1 and the other hand holds the handle sleeve 38, the fire extinguishing is more stable, which can be reused compared with the prior art, reduces the use cost, and also increases the stability of fire extinguishing by using the auxiliary holding method.

[0036] In addition, the rubber pad 22 can seal the handheld aerosol fire extinguisher 1 and the outer sleeve 21, and the sealing baffle 37 can seal the limiting sliding groove 31, so as to avoid the aerosol fire extinguishing agent from being sprayed out between the outer sleeve 21 and the handheld aerosol fire extinguisher 1 or from the limiting sliding groove 31.

[0037] In addition, it should be noted that the contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above-mentioned embodiments are only for clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. Based on the above disclosure, other changes or modifications can also be made by those skilled in the art, and these changes or modifications are still within the scope of the present disclosure.
