Description

TECHNICAL FIELD

[0001] The application relates to the technical field of fire extinguishers, in particular to a protective fire extinguisher. BACKGROUND

[0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to extinguish fires.

[0003] A high-protection fire extinguisher is disclosed in Chinese Patent No. CN222286277U, issued on January 12, 2024, which comprises a fire extinguisher body, a connecting pipe and a nozzle. The connecting pipe is in communication with the fire extinguisher body and can spray the substances in the fire extinguisher body out of the nozzle. A protection assembly is arranged at the nozzle of the connecting pipe. One side of the protection assembly extends away from the side facing the nozzle to form a fireproof part. The fireproof part can prevent the hands from being burned by the flames during fire extinguishing.

[0004] In the application, the protection assembly can block the fire and prevent the user from being burned by the flames. The protection assembly can also precisely aim at the fire source for fire extinguishing. The arrangement of the protection assembly can also give the user of the fire extinguisher a psychological hint, thereby reducing the fear or fear of the flames and increasing the efficiency of fire extinguishing. However, the inventor believes that the protection part in the application cannot be adjusted and can only be in an open state all the time, which is not convenient for the storage of the fire extinguisher. Moreover, the protection part is a single-layer structure and can only block the flames. Since the outer flame temperature of the flame is high, the user can be easily scalded by the high temperature transmitted from the protection part. UTILITY MODEL CONTENT

[0005] The application provides a protective fire extinguisher with better protection effect and convenient storage.

[0006] The application provides a protective fire extinguisher with the following technical solutions:

[0007] A protective fire extinguisher comprises a main body, a spray pipe and a protection mechanism.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. This application uses a movable sliding sleeve to change the state of the folding bracket, thereby changing the state of the fireproof layer. This allows the fireproof layer to be folded or unfolded. When fire extinguishing is needed, the sliding sleeve can be used to unfold the fireproof layer to block the flames and prevent the user from being burned. When fire extinguishing is not needed, the fireproof layer and the heat insulation layer can be folded up, without taking up too much space. This makes it easy to store the fire extinguisher and prevents it from being damaged by being constantly unfolded. By setting up the fireproof layer and the heat insulation layer, the user can be prevented from being burned by the flames, while the temperature inside the heat insulation layer can be reduced to prevent the user from being burned by the temperature of the outer flame.

[0014] 2. By setting up a cooperative structure of the first fixed seat, the second fixed seat and the sliding sleeve, the structure of the protective layer and the heat insulation layer is more stable when they are in the unfolded or retracted state. Attached Figure Description

Detailed Implementation

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a protective fire extinguisher, such as Figures 1 to 7 As shown, it includes a main body 1, a nozzle 2, and a protective mechanism 3. One end of the nozzle 2 is connected to the main body 1, and the other end is connected to a nozzle 4. The protective mechanism 3 is connected to the nozzle 2 and is located between the nozzle 4 and the main body 1. The main body 1 is used to output extinguishing agent into the nozzle 2. The extinguishing agent is sprayed out through the nozzle 4 to extinguish the fire. The protective mechanism 3 is used to stop the flames during fire extinguishing to prevent the user from being burned by the flames when extinguishing the fire at a close distance.

[0025] like Figures 2 to 4As shown, the protective mechanism 3 includes a first fixed base 31, a second fixed base 32, multiple folding brackets 33, a sliding sleeve 34, a fireproof layer 35, and a heat insulation layer 36. The first fixed base 31 and the second fixed base 32 are sequentially fixed to the outer periphery of the nozzle 2 along the direction from the nozzle 4 to the main body 1, with a gap between them. The sliding sleeve 34 is slidably connected to the nozzle 2 and located in the gap. The multiple folding brackets 33 are arranged radially, with one end of each bracket hinged to the first fixed base 31 and the other end hinged to the sliding sleeve 34. The sliding sleeve 34 is used to lock the multiple folding brackets 33 by cooperating with the first fixed base 31 or the second fixed base 32. The fireproof layer 35 is snapped onto the multiple folding brackets 33. Thus, by moving the sliding sleeve 34, the state of the folding bracket 33 can be changed, thereby changing the state of the fireproof layer 35, allowing the fireproof layer 35 to be folded or unfolded. When fire extinguishing is needed, the sliding sleeve 34 can be operated to unfold the fireproof layer 35 to stop the flames and prevent the user from being burned. When fire extinguishing is not needed, the fireproof layer 35 and the heat insulation layer 36 can be folded up, not taking up too much space, making it easy to store the fire extinguisher while preventing damage from being constantly unfolded. By setting the fireproof layer 35 and the heat insulation layer 36, the temperature inside the heat insulation layer 36 can be reduced while preventing burns from flames, preventing the user from being burned by the outer flame temperature. Compared with the prior art, the protective fire extinguisher of this application is easier to store and has a better protective effect.

[0026] like Figure 3 As shown, the folding bracket 33 includes a first frame 331 and a second frame 332. The first frame 331 has a sliding groove 3311 along its length. One end of the second frame 332 is slidably connected to the sliding groove 3311, and the other end is hinged to the sliding sleeve 34. The first frame 331 is hinged to the first fixed seat 31. A buckle 5 is provided on the outer side of the first frame 331. The fireproof layer 35 and the heat insulation layer 36 are snapped between the buckle 5 and the first frame 331. When the sliding sleeve 34 is at the first fixed seat... When the sliding sleeve 31 moves in the gap between the first frame 331 and the second fixed seat 32, it can drive the second frame 332 to move. The second frame 332 slides in the sliding groove 3311, which drives the first frame 331 to move. The first frame 331 drives the fireproof layer 35 and the heat insulation layer 36 to retract or unfold. When the sliding sleeve 34 moves toward the first fixed seat 31, the fireproof layer 35 and the heat insulation layer 36 gradually unfold to block the flame. When the sliding sleeve 34 moves toward the second fixed seat 32, the fireproof layer 35 and the heat insulation layer 36 gradually retract for easy storage.

[0027] like Figure 5 and Figure 6As shown, the first fixing seat 31 has a first thread 311, and the second fixing seat 32 has a second thread 321. The sliding sleeve 34 includes an inner sleeve 341 and an outer sleeve 342. The outer sleeve 342 is fitted around the outer periphery of the inner sleeve 341 and is hinged to the second frame 332. The inner periphery of the inner sleeve 341 has a third thread 3411 and a fourth thread 3412. The third thread 3411 is located at the end of the inner sleeve 341 near the first thread 311 and is used to mate with the first thread 311. The fourth thread 3412 is located at the end of the inner sleeve 341 near the second thread 321 and is used to mate with the second thread 321. The two ends of the inner sleeve 341 are respectively provided with a first convex ring 3413 and a second convex ring 3414, which respectively stop on the two ends of the outer sleeve 342. At the end, the inner sleeve 341 can slide within the gap and rotate axially. When the inner sleeve 341 moves toward the first fixed seat 31, it drives the outer sleeve 342 to move. The outer sleeve 342 drives the second frame 332 to move. The inner sleeve 341 rotates axially. At this time, the outer sleeve 342 does not rotate. The third thread 3411 engages with the first thread 311, fixing the protective layer and the heat insulation layer 36 in an open state for blocking flames and providing heat insulation. When the inner sleeve 341 rotates to release the connection between the third thread 3411 and the first thread 311, and moves toward the second fixed seat 32, it drives the outer sleeve 342 to move. The outer sleeve 342 drives the second frame 332 to move. The inner sleeve 341 rotates axially. At this time, the outer sleeve 342 does not rotate. The fourth thread 3412 engages with the second thread 321, fixing the protective layer and the heat insulation layer 36 in a closed state for easy storage.

[0028] The main body 1 is surrounded by a clamp 6, and a retaining ring 7 is connected to the clamp 6. A transition ring 8 is connected between the nozzle 4 and the first fixed seat 31. The transition ring 8 is engaged in the retaining ring 7, which makes it easier to store the protective mechanism 3.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
