DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] This embodiment provides an automatic fire extinguisher. The utility model can drive the conduit 8 to swing back and forth by setting a nozzle 9, and then drive the nozzle 9 to follow the left and right reciprocating swing, thereby increasing the spraying range of the fire extinguishing material in the shell 7, and then increasing the coverage of the fire source, thereby improving the fire extinguishing efficiency, further reducing property losses, and having a high safety factor.

[0022] See also Figure 1 to Figure 4 The automatic fire extinguisher includes a box body 1. A cover plate 2 is arranged on the top of the box body 1, which can limit the electric push rod 11 and the pressure plate 12. When the telescopic end of the electric push rod 11 drives the pressure plate 12 to move downward, the pressure plate 12 presses the control switch 10 downward, and an upward thrust is generated when pressing. At this time, the cover plate 2 can block the thrust to avoid the failure of pressing the control switch 10.

[0023] A set of limiting mechanisms 3 is provided on the outer side of the cover plate 2 .

[0024] The limiting mechanism 3 includes a connecting plate 301 , the outer surface of which is fixedly connected to the outer surface of the cover plate 2 , an insert rod 302 is slidably connected inside the connecting plate 301 , and a pull plate 303 is fixedly connected to the outer surface of the insert rod 302 .

[0025] The outer surface of the insertion rod 302 is slidably connected to the second connecting plate 304 , and the outer surface of the second connecting plate 304 is fixedly connected to the outer surface of the box body 1 . The outer surface of the insertion rod 302 is sleeved with an elastic member 305 .

[0026] The elastic member 305 is made of a spring, which deforms when subjected to force and stores potential energy, and releases the potential energy and recovers its deformation when the force disappears.

[0027] One end of the elastic member 305 is fixedly connected to the outer surface of the pull plate 303 , and the other end of the elastic member 305 is fixedly connected to the outer surface of the connecting plate 1 301 .

[0028] By pulling the pull plate 303, the insertion rod 302 can be driven to move with it, and then the insertion rod 302 can be pulled out from the inside of the connecting plate 304 and the limit on the connecting plate 304 can be released, and then the cover plate 2 can be taken out. At the same time, the pull plate 303 will stretch the elastic member 305, and then the elastic member 305 can be deformed and have a certain potential energy. After releasing the pull plate 303, the deformed elastic member 305 will release the potential energy, thereby driving the pull plate 303 and the insertion rod 302 to move in the opposite direction, achieving a rapid reset effect of the pull plate 303 and the insertion rod 302.

[0029] A temperature sensor 4 is disposed on the outer side of the box body 1 . A controller 5 is disposed on the outer side of the box body 1 . The controller 5 is electrically connected to the temperature sensor 4 .

[0030] The controller 5 is provided with a protective shell on its outer shell, which can be made of high temperature resistant material to prevent the controller 5 from being damaged by fire and ensure its normal operation. The controller 5 is not only electrically connected to the temperature sensor 4, but also electrically connected to the electric push rod 11 and the electric push rod 2 602.

[0031] A swing mechanism 6 is provided on the outer side of the box body 1 .

[0032] The swing mechanism 6 includes a limit frame 601, and a limit slide groove is provided on the inner side of the limit frame 601, which can limit the movable plate 603 and increase the stability during movement. The outer surface of the limit frame 601 is fixedly connected to the outer surface of the box body 1, and the outer surface of the limit frame 601 is fixedly connected to the electric push rod 2 602, and the telescopic end of the electric push rod 2 602 is fixedly connected to the movable plate 603, and the outer surface of the movable plate 603 is slidably connected to the inside of the limit frame 601.

[0033] The outer surface of the movable plate 603 is fixedly connected with a connecting rod 604 , and one end of the connecting rod 604 away from the movable plate 603 is fixedly connected with a collar 605 , and the collar 605 is sleeved on the outer side of the conduit 8 .

[0034] After the electric push rod 2 602 is started, the telescopic end of the electric push rod 2 602 will drive the moving plate 603 to move back and forth, and then the moving plate 603 will drive the connecting rod 604 and the ring 605 to follow the left and right reciprocating motion, and the moving ring 605 will drive the inner conduit 8 to follow the reciprocating motion, and then drive the nozzle 9 to follow the left and right reciprocating swing, thereby increasing the spraying range of the fire extinguishing material in the shell 7, and then increasing the coverage of the fire source, thereby improving the fire extinguishing efficiency, further reducing property losses, and having a high safety factor.

[0035] A shell 7 is provided inside the box body 1, and a conduit 8 is connected to the inner thread of the shell 7. The end of the conduit 8 away from the shell 7 is fixedly connected to a nozzle 9. A control switch 10 is installed on the top of the shell 7. An electric push rod 11 is fixedly connected to the bottom surface of the cover plate 2, and a pressure plate 12 is fixedly connected to the telescopic end of the electric push rod 11.

[0036] Working principle: When the utility model is in use, the temperature sensor 4 can detect the high temperature abnormality signal, and then the temperature sensor 4 will transmit the signal to the controller 5. When the controller 5 receives the signal, it will control the start-up of the electric push rod 11 and the electric push rod 2 602. At this time, the telescopic end of the electric push rod 11 will drive the pressure plate 12 to move downward, so that the pressure plate 12 presses the control switch 10 downward, and then the fire extinguishing material in the shell 7 will be sprayed to the fire source through the conduit 8 and the nozzle 9. At the same time, the telescopic end of the electric push rod 2 602 will drive the movable plate 603 to move back and forth, and then the movable plate 603 will drive the connecting rod 604 and the ring 605 to follow the left and right reciprocating motion. The moving ring 605 will drive the inner conduit 8 to follow the reciprocating motion, and then can drive the nozzle 9 to follow the left and right reciprocating swing, so that the spraying range of the fire extinguishing material in the shell 7 can be increased, thereby increasing the coverage of the fire source, thereby improving the fire extinguishing efficiency, further reducing property losses, and having a high safety factor.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
