DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application discloses an automatic fire extinguishing device, such as Figure 1 As shown, the portable fire extinguisher 2 includes a cabinet 1, a portable fire extinguisher 2 disposed in the cabinet 1, and a starter 3 for driving the portable fire extinguisher 2. The portable fire extinguisher 2 includes a bottle 21, a handle 23 disposed above the bottle 21, and a pressure handle 22 rotatably connected to the handle 23. The pressure handle 22 is rotated downward to spray the fire extinguishing substance in the bottle 21. The starter 3 is arranged in the cabinet 1 and can abut against the upper end of the pressure handle 22 and drive the pressure handle 22 to rotate downward. The starter 3 can select a hard structure, so one end of the starter 3 is rotatably connected to the inside of the cabinet 1, and the other end extends out of the cabinet 1 and can rotate vertically. In this embodiment, the starter 3 selects a rope structure, that is, a steel wire rope. One end of the starter 3 is fixed inside the cabinet 1, and the other end of the starter 3 is horizontally passed through the outside of the cabinet 1, and the heights of both ends of the starter 3 are lower than the lower end surface of the pressure handle 22. Therefore, when one end of the starter 3 outside the solid body is stressed, the starter 3 is stressed and tightened, thereby applying force to the pressure handle 22 to spray the fire extinguishing material in the bottle 21.

[0036] Both ends of the trigger 3 are located on the same side of the handheld fire extinguisher 2. A guide member 11 is further provided on the other side of the handheld fire extinguisher 2. The guide member 11 is a guide wheel in this embodiment. The guide member 11 is rotatably connected to the inner wall of the cabinet 1 for fixing the trigger 3. The trigger 3 passes over the top of the pressure handle 22 and then bypasses the guide member 11, and passes under the handle 23 and penetrates to the outside of the cabinet 1. In this way, when the driving member 52 outside the cabinet 1 is subjected to force, the driving member 52 located above the guide member 11 can move downward, causing the pressure handle 22 to rotate, thereby realizing the spraying of the fire extinguishing substance in the bottle 21.

[0037] like Figure 1 and Figure 2 As shown, in order to keep the position of the starter 3 fixed after the starter 3 is pulled outward so that the bottle 21 can continue to spray the fire extinguishing material, the cabinet 1 is also provided with a check assembly 4 to prevent the starter 3 from retracting into the cabinet 1. The check assembly 4 includes a check block 42 and an elastic member 43 for driving the check block 42 to rotate. A guide ring 41 is fixedly connected to the cabinet 1, and the starter 3 is inserted through the guide ring 41 and slides in the guide ring 41. A mounting groove 411 is coaxially provided on the end surface of the guide ring 41 away from the cabinet 1, and a plurality of check blocks 42 are circumferentially arranged in the mounting groove 411. The check blocks 42 are rotatably connected in the mounting groove 411, and the end of the check block 42 close to the starter 3 is inclined toward the direction away from the cabinet 1, and the check block 42 abuts against the outer wall of the starter 3. A cover plate 44 that closes the opening of the mounting groove 411 is clamped on the guide ring 41. In this embodiment, the elastic member 43 is a spring. One end of the elastic member 43 abuts against the cover plate 44, and the other end of the elastic member 43 abuts against the side of the check block 42 away from the cabinet 1. The elastic member 43 is located on the side of the rotation axis of the check block 42 close to the starter 3. When the starter 3 moves toward the outside of the cabinet door, the end of the check member close to the starter 3 rotates in the direction away from the cabinet 1. When the starter 3 does not move, the check block 42 abuts against the starter 3 so that the starter 3 cannot be retracted into the cabinet 1 again.

[0038] like Figure 1 As shown, in order to make the starter 3 more labor-saving when pulling, a handle 31 is further provided at one end of the starter 3 located outside the cabinet 1. The handle 31 is arranged in a ring shape and is fixed to the end of the starter 3 located outside the cabinet door. When the starter 3 needs to be moved, only force needs to be applied to the handle 31 to move the starter 3.

[0039] like Figure 3As shown, in order to ensure that the entire hand-held fire extinguisher can be stably placed in the cabinet 1 when the pressure handle 22 is subjected to downward pressure, a limit seat 12 is fixed to the inner wall of the cabinet 1 by bolts, and a limit groove 121 is opened at the upper end of the limit seat 12. The limit groove 121 penetrates the side wall of the inner wall of the cabinet 1 connected to the limit seat 12 away from it, and the handle 23 can be placed in the limit groove 121. Therefore, when the handle 23 is subjected to pressure applied by the pressure handle 22, the height of the handle 23 can remain unchanged, so that the fire extinguishing material in the bottle body 21 can be normally sprayed out after the pressure handle 22 is rotated.

[0040] Since the latch between the handle 23 and the pressure handle 22 has been pulled out after the handheld fire extinguisher 2 is placed in the cabinet 1, if the starter 3 is directly pressed on the pressure handle 22, the pressure handle 22 will move downward to a certain extent under the action of pressure, resulting in a certain leakage of the fire extinguishing material even when it is not necessary to spray. Therefore, a pressing member 13 is also provided in the cabinet 1. The pressing member 13 is provided above the pressure handle 22. The pressing member 13 moves vertically in the limiting groove 121. A pressing groove 131 is provided at the lower end of the pressing member 13. The pressing groove 131 penetrates the side wall of the cabinet 1 inner wall to which the pressing member 13 is connected, and the pressure handle 22 is provided in the pressing groove 131. The lower end of the pressing member 13 is also provided with a receiving groove 132, which is connected to the inner cavity of the pressing groove 131. The two side walls of the limiting seat 12 are penetrated with guide grooves 122 which are connected to the inner cavity thereof, and the guide grooves 122 penetrate the upper end surface of the limiting seat 12. A magnetic member 32 is sleeved on the starting member 3, which can be embedded in the receiving groove 132 and the guide groove 122 to move vertically, and can be adsorbed in the receiving groove 132, so that when the starting member 3 does not need to move, a gap is left between the magnetic member 32 and the upper end surface of the pressing handle 22, so that the pressing handle 22 will not be subjected to the downward pressure applied by the starting member 3.

[0041] like Figure 4As shown, the pressing member 13 is slidably arranged on the inner wall of the cabinet 1, and a clearance groove is arranged on the back of the cabinet 1. A driving assembly 5 for driving the pressing member 13 to move vertically is arranged in the clearance groove. The driving assembly 5 can use a linear drive structure such as an oil cylinder, an air cylinder, an electric push cylinder, etc. that drives the pressing member 13 to move linearly, and can also use a mechanism that drives the pressing member 13 to move linearly through force conversion. In this embodiment, the driving assembly 5 includes a lead screw 51 that is rotatably connected to the installation groove 411 and a driving member 52 that drives the lead screw 51 to rotate. The driving member 52 uses a motor. The lead screw 51 is vertically arranged, one end of the pressing member 13 passes through the cabinet 1 and moves vertically along the cabinet 1. The lead screw 51 is arranged at one end of the pressing member 13 that passes through the cabinet 1 and is threaded with the pressing member 13. The driving member 52 is fixed in the clearance groove with bolts, and the free end of the driving member 52 is coaxially fixed with one end of the lead screw 51, thereby driving the lead screw 51 to rotate. The cabinet 1 is also provided with a smoke sensor for detecting whether a fire has occurred. The smoke sensor is electrically connected to a control unit provided in the cabinet 1, and the control unit is electrically connected to a driving member 52. Thus, after the smoke sensor senses that the smoke concentration reaches a standard, the control unit can control the driving member 52 to work, thereby driving the pressing member 13 to move downward to realize the spraying of fire extinguishing substances.

[0042] The implementation principle of this embodiment is as follows: when a fire occurs, the smoke sensor transmits the detected smoke concentration to the processing unit, and when the vertical value received by the processing unit reaches the set value, the processing unit controls the driving member 52 to work, and the pressing member 13 moves downward under the drive of the screw rod to rotate the pressure handle 22 downward, so that the fire extinguishing material in the bottle 21 is sprayed out. When the smoke sensor or an electronic component fails, the handle is manually pulled to move the starter 3 toward the outside of the cabinet 1. During the movement of the starter 3, the magnetic member 32 moves downward to mobilize the pressure handle 22 to rotate downward, so that the bottle 21 sprays the fire extinguishing material.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
