Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to an aerosol fire-extinguishing device with a sealing mechanism. Background Art

[0002] Firefighting equipment refers to equipment used for firefighting, fire prevention and fire accidents. Aerosol fire extinguishing devices are fire extinguishers that suppress fires by releasing aerosol particles. Aerosol fire extinguishing devices can produce a fine cloud of aerosol particles in a fire scene. These particles have fire extinguishing properties and form a very effective fire extinguishing agent in the air. Currently, common aerosol fire extinguishing devices are usually aerosol fire extinguishers. The fire extinguishing operation steps of existing aerosol fire extinguishers are usually to pull out the bottom safety ring, open the cover on the top of the fire extinguisher, and then press the button on the surface of the fire extinguisher to extinguish the fire. However, the above steps are relatively cumbersome. For people who lack experience in fire fighting, when they encounter a fire, they usually lose control of their emotions and find it difficult to stay calm. When the on-site personnel are in a tense state, it takes a certain amount of time to complete the above steps.

[0003] The implementation of the utility model aims to provide an aerosol fire extinguishing device with a sealing mechanism to solve the problems raised in the above background technology. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example

[0028] Reference Figure 1-5An aerosol fire extinguishing device with a sealing mechanism includes an aerosol fire extinguisher body 1, a swivel 2 and a swivel base 3. The aerosol fire extinguisher body 1 includes a bottle body, an aerosol nozzle 12 and a safety pull ring 14. A valve is provided on the inner side of the aerosol nozzle 12, and the interior of the bottle body is filled with high-pressure gas and aerosol fire extinguishing agent. When the button 10 is pressed down, the valve at the bottom of the aerosol nozzle 12 will open, so that the high-pressure gas inside the bottle body carries the aerosol fire extinguishing agent to be sprayed out, thereby completing the fire extinguishing operation.

[0029] A swivel 2 is provided on the outer side of the aerosol fire extinguisher body 1, and a swivel base 3 is provided on the inner side of the swivel 2, a trigger ring 9 is fixedly connected to the inner side of the swivel 2, the swivel base 3 is circular as a whole, and the inner side of the swivel base 3 is fixedly connected to the aerosol fire extinguisher body 1, the swivel 2 is movably connected to the upper surface of the swivel base 3, and a button 10 is provided on the outer surface of the aerosol fire extinguisher body 1. When the device needs to be used, the staff can rotate the swivel 2 to make the swivel 2 rotate on the upper end of the swivel base 3, and start the device by squeezing the button 10 through the trigger ring 9.

[0030] A connecting rod 4 is fixedly connected to the upper surface of the swivel 2, and a cutting swivel 7 is fixedly connected to the upper end of the connecting rod 4, a cutting blade 11 is fixedly connected to the bottom of the cutting swivel 7, an aluminum film 8 is fixedly connected to the upper surface of the aerosol fire extinguisher body 1, a fixed shell 5 is movably connected to the outer side of the cutting swivel 7, and a shell fixing block 6 is fixedly connected to the bottom of the fixed shell 5, three shell fixing blocks 6 are equidistantly arranged around the bottom of the fixed shell 5, a connecting rod 4 is arranged on one side of the three shell fixing blocks 6, and the connecting rod 4 is tightly fitted to the side of the shell fixing block 6, three cutting blades 11 are equidistantly arranged at the bottom of the cutting swivel 7, and the initial position of the cutting blade 11 is arranged on the same vertical line corresponding to the shell fixing block 6, and the cutting blade 11 penetrates the main body of the aerosol fire extinguisher as a whole. The aluminum film 8 on the surface of the body 1 and the trigger ring 9 are arc-shaped as a whole, and the edges on both sides of the trigger ring 9 are arc-shaped. The button 10 is located on the inner side of the rotating ring 2 as a whole, and the button 10 and the trigger ring 9 are located on the same horizontal line, so that the rotating ring 2 only needs to rotate 110 to 120 degrees to make the trigger ring 9 squeeze the trigger button 10. At the same time, the outer shell fixing block 6 can also play a limiting role. In the process of rotating the rotating ring 2, due to the setting between the outer shell fixing block 6 and the connecting rod 4, the connecting rod 4 will touch the outer shell fixing block 6 on the other side after rotating 120 degrees. At the same time, the three equidistant cutting blades 11 on the inner side of the aluminum film 8 at this rotation angle can also cut the aluminum film 8 along the outer side of the aluminum film 8 to prevent the aluminum film 8 from affecting the injection efficiency of the aerosol nozzle 12.

[0031] The outer shell fixing block 6 is L-shaped as a whole, and one side of the outer shell fixing block 6 is fixedly connected to the aerosol fire extinguisher body 1 , so that the fixed outer shell 5 is fixedly connected to the outer side of the aerosol fire extinguisher body 1 through the outer shell fixing block 6 .

[0032] The upper end of the aerosol fire extinguisher body 1 is located at the bottom of the aluminum film 8 and is provided with an aerosol nozzle 12, and the bottom of the aerosol fire extinguisher body 1 is provided with a safety pull ring 14. When the button 10 is triggered, the upper end of the cutting blade 11 is fixedly connected to the cutting swivel 7, and at the same time, the lower end of the cutting blade 11 penetrates the aluminum film 8. The aluminum film 8 will also be synchronously cut by the three equidistantly arranged cutting blades 11, causing the aluminum film 8 to fall off. Even if the cutting is incomplete, the spray force of the aerosol nozzle 12 can spray off the aluminum film 8 that is still partially adhered.

[0033] A grip groove 13 is fixedly connected to the surface of the aerosol fire extinguisher body 1, and the surface of the grip groove 13 is provided with frosted particles, so that when on-site personnel need to hold the device, they can hold the grip groove 13. The frosted particles on the surface of the grip groove 13 enhance the friction force, reduce the spray force when the device is running, and reduce the risk of the device falling off from the palm of the person due to the recoil force.

[0034] Working principle: When personnel encounter a fire, they can hold the device, pull open the bottom safety pull ring 14, and then rotate the swivel 2 to make the swivel 2 rotate on the upper end of the swivel base 3, and start the device by squeezing the button 10 through the trigger ring 9. Then the high-pressure gas inside the device will carry the aerosol fire extinguishing agent and spray out from the aerosol nozzle 12 to complete the fire extinguishing operation. At the same time, in the placed state, the aluminum film 8 on the top of the aerosol fire extinguisher body 1 plays a role in sealing and protecting the aerosol nozzle 12 to prevent dust. Or impurities enter the aerosol nozzle 12, thereby ensuring that the spray effect of the aerosol nozzle 12 achieves an ideal effect during the subsequent fire extinguishing operation. When the on-site personnel rotate the swivel 2, the swivel can drive the cutting swivel 7 to rotate, so that the three cutting blades 11 equidistantly arranged at the bottom of the cutting swivel 7 cut the aluminum film 8, causing the aluminum film 8 to fall off. Even if the cutting is incomplete, the spray force of the aerosol nozzle 12 can spray off the aluminum film 8 that is still partially adhered, so as to avoid the influence of the aluminum film 8 on the aerosol output of the aerosol nozzle 12.

[0035] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
