DETAILED DESCRIPTION

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a remotely monitored automatic fire extinguishing device for kitchens includes a housing 1, an extinguishing agent bottle 2 installed inside the housing 1, and a movable push plate 3 slidably connected inside the extinguishing agent bottle 2. The movable push plate 3 has a disc-shaped structure, and a sealing ring is fitted around the periphery of the movable push plate 3. The outer wall of the sealing ring slides in contact with the inner wall of the extinguishing agent bottle 2. By setting the sealing ring, the fit between the periphery of the movable push plate 3 and the inner wall of the extinguishing agent bottle 2 is improved, thereby improving the airtightness at the connection between the movable push plate 3 and the inner wall of the extinguishing agent bottle 2.

[0021] The inner cavity of the fire extinguishing agent bottle 2 above the movable push plate 3 is filled with fire extinguishing agent. A gas cylinder 4 filled with high-pressure gas is installed in the box 1 on one side of the fire extinguishing agent bottle 2. A gas supply pipe 5 is installed on the exhaust end of the gas cylinder 4. The end of the gas supply pipe 5 away from the gas cylinder 4 is connected to the bottom end of the fire extinguishing agent bottle 2. A first solenoid valve 6 is installed on the middle section of the gas supply pipe 5. When the first solenoid valve 6 is opened, the high-pressure gas in the gas cylinder 4 can be transported through the gas supply pipe 5 to the fire extinguishing gas cylinder 4 below the movable push plate 3. The gas pressure pushes the movable push plate 3 to move upward along the fire extinguishing agent bottle 2.

[0022] An elastic clamp 18 is fixedly connected to the inner wall of the box 1. The fire extinguishing agent bottle 2 and the gas cylinder 4 are both fixed to the inner wall of the box 1 by the elastic clamp 18. The elastic clamp 18 is set to clamp and fix the gas cylinder 4 and the fire extinguishing agent bottle 2, so as to facilitate the replacement of the fire extinguishing agent bottle 2 and the gas cylinder 4 after use.

[0023] A nozzle 7 is fixedly connected to the top of the fire extinguishing agent bottle 2. A one-way valve 8 is installed on the middle section of the nozzle 7. The one-way valve 8 can isolate the air and prevent the fire extinguishing agent from deteriorating due to oxidation as much as possible. The end of the nozzle 7 away from the fire extinguishing agent bottle 2 extends to the side of the kitchen gas stove. A rotating nozzle 9 is rotatably connected to the end of the nozzle 7 near the gas stove. When the movable push plate 3 moves upward under the push of high pressure gas, it can squeeze the fire extinguishing agent above it into the nozzle 7 and deliver it along the nozzle 7 to the rotating nozzle 9, where it is sprayed out to extinguish the fire.

[0024] A temperature sensor 10 is installed on one end of the nozzle 7 near the rotating nozzle 9. A controller 14 is also installed on the outer wall of one side of the housing 1. The controller 14 is a wireless controller, which can be connected to a mobile phone via a wireless network to achieve remote monitoring.

[0025] The first electromagnetic valve 6 and the temperature sensor 10 are electrically connected with the controller 14. When the temperature sensor 10 detects that the temperature near the gas stove is too high, a signal is immediately transmitted to the controller 14. If there is no remote control, the controller 14 will automatically control the first electromagnetic valve 6 to open, so that the gas in the gas cylinder 4 is delivered to the bottom of the fire extinguishing agent bottle 2 through the gas pipeline 5, and the fire extinguishing agent is sprayed to extinguish the fire.

[0026] The box body 1 is also provided with a gas blocking pipe 11 in the cavity. The gas blocking pipe 11 is fixedly connected with connectors 12 at both ends. The two connectors 12 penetrate through one side wall of the box body 1 and are fixedly connected with the box body 1. The second electromagnetic valve 13 is installed in the middle section of the connector 12. The second electromagnetic valve 13 is electrically connected with the controller 14. The gas stove and the gas pipeline are connected through the gas blocking pipe 11. When the temperature sensor 10 detects that the temperature is too high, the controller 14 can control the second electromagnetic valve 13 to close to block the gas.

[0027] The controller 14 is provided with a display screen on the top outer side for displaying the temperature detected by the temperature sensor 10. The controller 14 is provided with control buttons on the bottom outer side for controlling the first electromagnetic valve 6 and the second electromagnetic valve 13. The display screen is arranged to display the temperature detected by the temperature sensor 10. The control buttons are arranged to facilitate the user to manually control the first electromagnetic valve 6 to open at the first time of fire, and to control the second electromagnetic valve 13 to close at the same time, so as to prevent gas leakage from causing explosion.

[0028] The box body 1 is fixedly connected with four matrix distributed ear plates 15 at the open end. The ear plates 15 are provided with sealing covers 16 on the outer side. Four bolts 17 corresponding to the ear plates 15 are arranged on the sealing covers 16. The bolts 17 are screwed and fixed with the ear plates 15 after penetrating through the sealing covers 16, so as to seal the open end of the box body 1.

[0029] It should be noted that the kitchen automatic fire extinguishing device can be remotely monitored. When in use, the box body 1 is installed near the kitchen stove. One end of the spray pipe 7 provided with the rotating nozzle 9 is installed on one side of the gas stove. The temperature sensor 10 is installed on the spray pipe 7, which can detect the temperature near the gas stove in real time. When the temperature sensor 10 detects that the temperature near the gas stove is too high, a signal is immediately transmitted to the controller 14. At this time, the controller 14 controls the first electromagnetic valve 6 to open, so that the high-pressure gas in the gas cylinder 4 can be delivered to the fire extinguishing gas cylinder 4 below the movable push plate 3 through the gas pipeline 5, and the movable push plate 3 is pushed up along the fire extinguishing agent bottle 2 by the gas pressure, so as to extrude the fire extinguishing agent above the movable push plate 3 into the spray pipe 7, and then deliver the fire extinguishing agent to the rotating nozzle 9 through the spray pipe 7, and then spray out through the rotating nozzle 9 to realize the automatic fire extinguishing function. The existing fire-fighting equipment needs to be manually operated, which not only has safety hazards, but also may not be able to extinguish the fire at the first time due to the failure to discover the fire in time, and has the problem of limited use.

[0030] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
