[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The purpose of the utility model is to provide an automatic fire extinguisher to solve the problems existing in the above-mentioned prior art. It has a simple structure, is stable and reliable, can effectively and timely extinguish the fire source, prevent the fire from spreading, and reduce the incidence of fire.
[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] The utility model provides an automatic fire extinguisher, such as Figure 1As shown, it includes a tank body 1, a tank cover 2 capable of blocking the tank body 1, and an electromagnetic starter. A one-way air outlet 4 is provided on the side wall at one end of the tank body 1, and the fire extinguishing agent or inert gas in the tank body 1 can be discharged through the one-way air outlet 4. The tank cover 2 is provided with a chamber 5, and a fusible alloy 6 is installed in the chamber 5. One end of the fusible alloy 6 is fixedly connected to a piston 7. When the tank cover 2 blocks the tank body 1, the piston 7 can extend into the tank body 1 and slide tightly with part of the inner wall of the tank body 1 to block the one-way air outlet 4. The side wall of the tank cover 2 is fixedly connected to the electromagnetic starter, and starting the electromagnetic starter can break the fusible alloy 6. A through hole 8 is provided on the side wall opposite to the position of the tank cover 2 and the electromagnetic starter, and the through hole 8 is used to connect the fusible alloy 6 with the outside. When the automatic fire extinguisher is in storage, after the tank body 1 of the automatic fire extinguisher is filled with fire extinguishing agent and inert gas, the pressure in the tank body 1 is between 0.5-0.6MP, the pressure in the tank body 1 gives the piston 7 an upward force, and the fusible alloy 6 gives the piston 7 a downward force, so that the piston 7 blocks the one-way air outlet 4; when there is a fire and the electromagnetic starter can be powered normally, after power is turned on, the electromagnetic starter can break the fusible alloy 6 installed in the chamber 5 of the tank cover 2, the fusible alloy 6 breaks, the piston 7 loses the downward force exerted by the fusible alloy 6, and the piston 7 is in the tank body 1 The piston 7 moves upward under the action of the pressure inside the tank body 1, so that the one-way air outlet 4 is opened, and the fire extinguishing agent is sprayed out from the one-way air outlet 4, thereby realizing automatic fire extinguishing; when there is a fire, but the electromagnetic starter cannot be powered normally, the fusible alloy 6 can directly sense the temperature from the through hole 8 connected to the outside world. When the melting point of the fusible alloy 6 is reached, the fusible alloy 6 automatically melts, and the piston 7 loses the downward force applied by the fusible alloy 6. The piston 7 moves upward under the action of the pressure inside the tank body 1, so that the one-way air outlet 4 is opened, and the fire extinguishing agent is sprayed out from the one-way air outlet 4, thereby realizing automatic fire extinguishing.
[0022] In the embodiment of the utility model, it is further preferred that the side wall of the tank body 1 is also provided with a one-way air filling hole 3, and the one-way air outlet 4 is closer to the tank cover 2 than the one-way air filling hole 3, so that the fire extinguishing agent and the inert gas can be filled into the tank body 1 through the one-way air filling hole 3. When filling the fire extinguishing agent into the tank body 1, the perfluorohexanone liquid (fire extinguishing agent) is first injected through the one-way air filling hole 3 to below the one-way air filling hole 3, the fusible alloy 6 and the piston 7 are installed in the tank cover 2, and then the tank cover 2 blocks the tank body 1. At this time, the pressure in the tank body 1 is relatively small, and the piston 7 is pressed to block the one-way air outlet 4 through the fusible metal, and then nitrogen is rushed into the tank body 1 from the one-way air filling hole 3 to pressurize it. The nitrogen accumulates from the bottom to the top and exerts an upward pressure on the piston 7. At the same time, the piston 7 is exerted with a downward pressure by the fusible metal. Therefore, the position of the piston 7 can block the one-way air outlet 4 to prevent nitrogen from leaking from the one-way air outlet 4.
[0023] It is further preferred in the embodiment of the utility model that there are multiple one-way air outlet holes 4, and the multiple one-way air outlet holes 4 are evenly distributed along the circumference of the tank body 1, which can make the fire extinguishing agent spray faster and over a larger range.
[0024] It is further preferred in the embodiment of the utility model that the fusible alloy 6 is fixedly connected to the piston 7 via a spring.
[0025] It is further preferred in the embodiment of the present invention that the piston 7 is made of rubber.

[0027] In the embodiment of the utility model, it is further preferred that the tank body 1 includes a connecting part and a filling part, the connecting part and the filling part are integrally formed, the connecting part is used to connect with the tank cover 2, and the filling part is used to fill the fire extinguishing agent and the inert gas, the connecting part is in the shape of a cylinder, and the filling part is in the shape of a rectangular parallelepiped. If the tank body 1 is cylindrical, since the cylindrical tank body 1 is subjected to force on the entire surface, once it explodes, it will explode as a whole like a bomb, while the rectangular tank body 1 has only one side subjected to the greatest force, which can well avoid this problem; and the rectangular tank body 1 is placed in a corner, and occupies a smaller volume.
[0028] It is further preferred in the embodiment of the utility model that the material of the tank body 1 and the tank cover 2 is stainless steel.
