The nozzle on the fire extinguisher body 1 is fixedly connected to the rotating plate 7. A control rope 8 is fixedly connected to the rotating plate 7. At least two buckles are fixedly connected to the rotating plate 7. The pipe connected to the nozzle on the fire extinguisher body 1 is clamped in the buckle to facilitate fixing the position of the nozzle, and the nozzle is set downward. The control rope 8 is made of soft and high-temperature resistant material to prevent the control rope 8 from breaking in a high-temperature environment.
[0027] A fixing plate 9 is fixedly connected to the inner wall of the fixing box 3, a spring 10 is fixedly connected to the upper surface of the fixing plate 9, the upper end of the spring 10 is fixedly connected to the lower surface of the push plate 6, one side wall of the fixing box 3 is open, and a cover plate is fixedly connected to the open end of the fixing box 3 by bolts, so as to facilitate the replacement of the fire extinguisher body 1.
[0028] A slide groove 11 is provided on the inner side wall of the fixed box 3 , and a sliding block 12 is fixedly connected to the side wall of the push plate 6 , and the sliding block 12 is slidably connected in the slide groove 11 .
[0029] A strip through hole 13 is opened on the side wall of the fixed box 3 opposite to the push plate 6, and a rotating shaft 14 is fixedly connected to the upper end of the rotating plate 7. The rotating shaft 14 is rotatably connected to the side wall of the strip through hole 13, and the side wall of the rotating plate 7 is in contact with the side wall of the strip through hole 13.
[0030] The top and side walls of the fixed box 3 are rotatably connected with guide pulleys 15 , one end of the control rope 8 is fixedly connected to the lower end of the rotating plate 7 , and the other end of the control rope 8 is passed through the guide pulley 15 and hangs down to one side of the fixed box 3 .
[0031] A pull rope 16 is fixedly connected to the pin of the fire extinguisher body 1. The end of the pull rope 16 away from the fire extinguisher body 1 passes through the side wall of the fixed box 3 and is fixedly connected to the control rope 8. The diameter of the pull rope 16 is smaller than the diameter of the control rope 8, and the tensile strength of the pull rope 16 is smaller than the tensile strength of the control rope 8. A circular through hole is opened on the fixed box 3 to facilitate the pull rope 16 to pass through and connect with the control rope 8.
[0032] Working principle: The fixing strip 4 is adhered to the wall tiles or glass door opposite to the gas stove in the kitchen, and the position of the rotating plate 7 is opposite to the position of the gas stove, so as to fix the position of the fixing box 3 and the fire extinguisher body 1, and then the end of the control rope 8 away from the rotating plate 7 is wound around the guide pulley 15 and stretched to the outside of the kitchen, and the end of the control rope 8 away from the rotating plate 7 is fixed to the wall outside the kitchen or the kitchen door by existing technical means such as adhesive.
[0033] When a fire occurs in the direction of the gas stove in the kitchen, the user can be outside the kitchen door and pull the control rope 8. Through the contraction of the control rope 8, the lower end of the rotating plate 7 is driven to rotate upward, and the nozzle on the fire extinguisher body 1 is driven to rotate upward, so that the nozzle of the fire extinguisher body 1 is relative to the flame. In the process of pulling the control rope 8 to the outside of the kitchen, the pull rope 16 is driven to be pulled to the outside of the fixed box 3. At the same time, the pull rope 16 drives the latch on the fire extinguisher body 1 to be pulled to one side of the fixed box 3, so that the latch is separated from the fire extinguisher body 1. When the latch on the fire extinguisher body 1 contacts the inner wall of the fixed box 3, it is difficult for the control rope 8 to pull the pull rope 16 out of the fixed box 3 due to the obstruction of the latch. Under the action of the blocking force of the pin, the pull rope 16 will break, which is convenient for the user to continue to control the rotation of the rotating plate 7 through the control rope 8. When the handle on the fire extinguisher body 1 is free from the restriction of the pin, due to the elastic force of the spring 10, the spring 10 pushes the push plate 6 upward. During the upward sliding process of the push plate 6, the handle on the fire extinguisher body 1 is pushed upward, the fire extinguisher body 1 is opened, and the fire extinguishing material is sprayed out through the nozzle, so as to extinguish the fire on the gas stove in the kitchen, avoiding the danger caused by the user carrying a fire extinguisher into the kitchen. At the same time, during the fire extinguishing process, the fire extinguishing material floating in the air is isolated in the kitchen through the kitchen door, which can effectively prevent the fire extinguishing material floating in the air from entering the user's body through the user's respiratory tract.
[0034] When the fire extinguisher body 1 needs to be replaced, turn the bolts on the fixing box 3, remove the cover plate, remove the pipe connected to the nozzle on the fire extinguisher body 1 through the buckle, take out the fire extinguisher body 1, and place the new fire extinguisher body 1 in the fixing box 3, clamp the nozzle on the new fire extinguisher body 1 on the buckle on the rotating plate 7, and then fix one end of the pull rope 16 on the pin on the new fire extinguisher body 1, pass the end of the pull rope 16 away from the fire extinguisher body 1 through the circular through hole and tie it to the control rope 8, so as to realize the replacement of the fire extinguisher body 1.
