[0003] The existing Chinese patent with publication number CN114030240B discloses a fireproof board with sound absorption and noise reduction, including edge sealing boards, the number of the edge sealing boards is two, and a first fireproof board arranged horizontally is arranged between the two edge sealing boards. The noise reduction effect is improved by the first fireproof board, the second fireproof board and the sound-absorbing board. The first noise reduction board, the second noise reduction board, the first sponge board, the second sponge board and the sound-absorbing board are arranged between the first fireproof board and the second fireproof board, so as to improve the noise reduction effect of the fireproof board. The first noise reduction board and the second noise reduction board can perform first noise reduction on noise, the first sponge board and the second sponge board can absorb noise, the sound-absorbing board increases the noise absorption effect, and the spring can improve the shock absorption effect.

[0004] The above-mentioned fireproof board has excellent noise reduction and sound absorption effects, and there is no need to pour water into the fireproof board to prevent water from flowing out when the fireproof board is disassembled, thereby reducing the difficulty of disassembly. However, the fireproof board does not have a fire extinguishing function, cannot actively extinguish a fire when the fire is small, cannot suppress the expansion of the fire, and cannot effectively protect property safety. Utility Model Content

[0005] The purpose of this application is to provide a fireproof board with fire extinguishing function in response to the above-mentioned technical problems. It can actively extinguish fire when the fire is small, and delay the spread of fire when the fire is large, thereby buying time for fire rescue and effectively protecting the property safety of users.

[0006] The present application provides a fireproof board with a fire extinguishing function, comprising a fireproof board body, wherein the fireproof board body comprises:

[0007] Flame retardant device, including air storage box, air outlet pipe, alloy sealing sheet and powder storage box;

[0008] Spraying device, including high-pressure nozzle, fuse chip, water outlet pump and water storage tank;

[0009] Among them, the air storage box stores inert gas, the powder storage box stores dry powder, the air storage box is connected to the air outlet pipe, the alloy sealing sheet is matched with the air outlet pipe, the high-pressure nozzle is connected to the water storage tank through the water outlet pump, and the fuse chip is placed at the water outlet pump.

[0010] In this technical solution, a flame retardant device and a spraying device are arranged in the fireproof board body. The flame retardant device is provided with a gas storage tank, an air outlet pipe, an alloy sealing piece and a powder storage tank. When a fire occurs near the fireproof board body, the alloy sealing piece melts under the influence of high temperature, thus dredging the air outlet pipe, facilitating the diffusion of the inert gas inside the gas storage tank along the air outlet pipe to the fire area to inhibit the spread of the fire. At the same time, the dry powder inside the powder storage tank is sprayed to the fire area to extinguish the fire and delay the spread of the fire. The spraying device is provided with a high-pressure nozzle, a fusing chip, a water outlet pump and a water storage tank. After the fusing chip is melted under the influence of the high temperature of the fire, the water outlet pump is unblocked at this time, facilitating the high-pressure nozzle to obtain water from the water storage tank through the water outlet pump and spraying the water to the fire area, thereby improving the fire extinguishing efficiency. When a fire occurs in the fireproof board body, it can transport inert gas to the disaster area, and spray dry powder and water. The three cooperate with each other to extinguish the fire, can actively extinguish the fire when the fire is small, and delay the spread of the fire when the fire is large, so as to gain time for fire fighting and rescue, and thus effectively protect the property safety of users.

[0011] Furthermore, the flame retardant device includes:

[0012] An electromagnet, which is connected to the alloy sealing piece;

[0013] A permanent magnet, which is placed inside the fireproof board body;

[0014] A rotating handle, which is placed on both sides of the fireproof board body;

[0015] A spiral blade, which is placed at the powder storage tank;

[0016] Among them, the electromagnet is connected to the permanent magnet after being energized.

[0017] In this technical solution, a rotating handle is arranged in the flame retardant device, a spiral blade is arranged on the powder storage tank, an electromagnet is connected to the alloy sealing piece, and a permanent magnet is arranged on the fireproof board body. When the user discovers a fire, at this time, the alloy sealing piece and the fusing chip inside the fireproof board body have not reached the melting point. The user rotates the rotating handle on the fireproof board body. After the rotating handle rotates, it can trigger the electromagnet and the spiral blade to be energized. After the electromagnet is energized, it is connected to the permanent magnet. At this time, the cooperation between the alloy sealing piece and the air outlet pipe is released, facilitating the air outlet pipe to spray inert gas to the fire area. After the spiral blade is energized, it can rotate quickly to quickly spray the dry powder inside the powder storage tank to suppress the fire, facilitating the user to manually control the fireproof board body to extinguish the fire, and the practicability and safety are relatively strong.

[0018] Furthermore, the rotating handle includes:

[0019] A first spring, and the rotating handle is connected to the fireproof board body through the first spring;

[0020] A first magnet;

[0021] First contact;

[0022] Wherein, the powder storage box is provided with a second magnet and a second contact. The first magnet and the second magnet cooperate with each other. After the first contact and the second contact come into contact, the spiral blade and the electromagnet are powered on.

[0023] In this technical solution, by arranging a first spring, a first magnet and a first contact in the rotating handle, and a second magnet and a second contact in the powder storage box, the rotating handle and the fireproof board body are connected by the first spring, and the first magnet and the second magnet cooperate with each other. When the user needs to rotate the rotating handle, first pull down the rotating handle to release the cooperation between the rotating handle and the alloy sealing piece. At this time, the first magnet in the rotating handle and the second magnet in the powder storage box cooperate and are connected, that is, the first contact and the second contact come into contact, triggering the spiral blade and the electromagnet to be powered on. After the electromagnet is powered on, it is connected to the permanent magnet to release the cooperation between the alloy sealing piece and the air outlet pipe, facilitating the air outlet pipe to spray inert gas. After the spiral blade is powered on, it rotates quickly and can quickly spray dry powder, enabling the user to control the fireproof board body to extinguish fire through simple manual operation, which is relatively convenient to use.

[0024] Further, the spraying device includes:

[0025] Second spring;

[0026] A water receiving head, which is connected to the water storage tank;

[0027] A smoke sensor, which is connected to the fusing chip;

[0028] A buzzer, which is connected to the smoke sensor;

[0029] Wherein, the high-pressure nozzle and the fireproof board body are connected by a second spring.

[0030] In this technical solution, by arranging a second spring in the spraying device, the high-pressure nozzle and the fireproof board body are connected by the second spring, so that when the high-pressure nozzle sprays water to extinguish fire, it vibrates continuously through the second spring, and the high-pressure nozzle can spray water in various directions, covering a wider fire extinguishing range and improving the fire extinguishing efficiency. The water storage tank is connected with a water receiving head, which is convenient for connecting with the fire fighting water supply system to expand the spraying water volume of the spraying device to ensure fire extinguishing. The spraying device is also provided with a smoke sensor, and the smoke sensor is connected to the fusing chip and the buzzer. When the smoke sensor detects the smoke generated by the fire, it triggers the fusing chip to fuse and the buzzer to alarm. After the fusing chip fuses, it triggers the water pump and the high-pressure nozzle to work, enabling the fireproof board body to automatically extinguish fire through smoke and temperature, with a relatively high degree of automation. The buzzer can remind the user to pay attention to the situation in the room, facilitating the user to escape in time and playing an alarm role.

[0031] Further, the fireproof board body further includes:

[0032] A rotating plate, which is rotatably connected to the fireproof board body;

[0033] A groove, which is matched with the rotating plate;

[0034] Wherein, the rotating handle is placed in the groove.

[0035] In this technical solution, by arranging a rotating plate and a groove in the fireproof board body and placing the rotating handle in the groove, when the fireproof board body is idle, the rotating plate and the groove are matched, and the rotating plate can block the rotating handle, making the appearance of the fireproof board body more coordinated, improving the aesthetics of the fireproof board body when it is idle, and preventing external dust from entering the inside of the fireproof board body, playing a certain protective role. When it is necessary to use the rotating handle to extinguish the fire, rotate the rotating plate and then rotate the rotating handle to extinguish the fire, and the operation is relatively convenient.

[0036] Further, the fireproof board body is further provided with a fireproof layer, a noise reduction layer and a sound absorption layer.

[0037] In this technical solution, by arranging a fireproof layer, a noise reduction layer and a sound absorption layer in the fireproof board body, the fireproof layer can prevent the fireproof board body from burning rapidly under the influence of fire and avoid affecting the fire extinguishing function of the fireproof board body. The noise reduction layer and the sound absorption layer can endow the fireproof board body with excellent noise reduction and sound absorption effects, effectively improving the user experience.

[0038] The beneficial effects of this application are:

[0039] 1. When a fire breaks out near the fireproof board body, the flame retardant device can spray inert gas and dry powder onto the fire area to extinguish the fire and delay the spread of the fire, and the sprinkler device can spray water onto the fire area to improve the fire extinguishing efficiency. The inert gas, dry powder and water cooperate with each other to extinguish the fire, can actively extinguish the fire when the fire is small, and delay the spread of the fire when the fire is large, buying time for fire fighting and rescue.

[0040] 2. After the user rotates the rotating handle, the electromagnet and the spiral blade can be powered on. After the electromagnet is powered on, it is connected to the permanent magnet. At this time, the cooperation between the alloy sealing piece and the air outlet pipe is released, facilitating the air outlet pipe to spray inert gas into the fire area. After the spiral blade is powered on, it can rotate quickly to quickly spray the dry powder in the powder storage tank to suppress the fire. The user can manually control the fireproof board body to extinguish the fire, improving the practicability and safety of the fireproof board body.

[0041] 3. When the high-pressure nozzle sprays water for fire extinguishing, it can continuously vibrate through the second spring, enabling the high-pressure nozzle to spray water in various directions, with a relatively wide fire extinguishing range and improved fire extinguishing efficiency. When the smoke sensor detects smoke, it can trigger the fuse chip to fuse and the buzzer to alarm. The fireproof board body automatically extinguishes fire based on smoke and temperature, improving the degree of automation. The buzzer has an alarming function and can remind users to escape in time. BRIEF DESCRIPTION OF THE DRAWINGS
