DETAILED DESCRIPTION

[0030] Example 1

[0031] See also Figure 1-Figure 7 , wherein a self-protective electromagnetic signal switch module comprises a base 1 and an upper base 2 on the base 1, the upper base 2 comprises a fitting seat 21, a diaphragm 22, a transparent cover 23, a yoke frame 24 and an electromagnetic coil 25, the fitting seat 21 is fixedly mounted on the upper end of the base 1, a diaphragm 22 is provided on the upper end of the fitting seat 21, a transparent cover 23 is mounted on the upper end of the diaphragm 22, two yoke frames 24 located on the upper surface of the diaphragm 22 are mounted inside the transparent cover 23, and an electromagnetic coil 25 is fixedly mounted on one side of the two yoke frames 24;

[0032] The upper surface of the base 1 is also symmetrically mounted with side boxes, which include a first dry powder box 501 and a second dry powder box 502;

[0033] A heat-conducting frame 3 is fixedly installed on the outer side of the electromagnetic coil 25. The heat-conducting frame 3 includes a bottom foot 31 and a top pipe 32. The bottom foot 31 is fixedly installed inside the fitting seat 21. A top pipe 32 is provided on the upper surface of the bottom foot 31. The top pipe 32 is used to fit the outer surface of the electromagnetic coil 25 and transfer the heat in the electromagnetic coil 25.

[0034] Small high-pressure tanks 38 are installed on both sides of the transparent cover 23. One end of the small high-pressure tank 38 is fixedly installed with a connecting outer tube 37. The interior of the small high-pressure tank 38 is filled with carbon dioxide gas. The small high-pressure tank 38 is used to provide gas filling to the interior of the diaphragm 22. The bottom end of the fitting seat 21 is symmetrically installed with a second spring 39. The second spring 39 is used to provide an elastic force for the fitting seat 21.

[0035] The bottom foot 31 is symmetrically provided with transverse slot holes 33, and a push rod 35 is movably installed inside the transverse slot hole 33. One end of the push rod 35 is provided with a cone head. One end of the two push rods 35 is fixedly installed with a first spring 34. A connecting outer tube 37 is fixedly installed between one end of the two first springs 34. One end of the push rod 35 is used to increase the friction between the fitting seat 21 and the side box, and is used to fix the fitting seat 21 between the two side boxes. The first spring 34 is used to provide a lateral displacement reset function for the push rod 35.

[0036] The bottom foot 31 is provided with a conveying hole groove 4, which includes a first through hole 41 and a second through hole 42. The bottom foot 31 is provided with a first through hole 41 located at the upper end of the transverse groove hole 33, and one side of the first through hole 41 is provided with a second through hole 42 located at the upper end of the transverse groove hole 33.

[0037] A connecting groove 36 is provided on the outer side of the top rod 35, and the connecting groove 36 is used to connect the first through hole 41 and the second through hole 42. One end of the second through hole 42 is connected to the connecting outer tube 37. The second through hole 42 is used to send the gas inside the small high-pressure tank 38 into the top tube 32. The first through hole 41 is connected to the connecting outer tube 37.

[0038] A contact rubber ring 7 is also installed inside the top pipe 32. The contact rubber ring 7 includes a heat-conducting silicone rubber 71, a flow gap 72 and a connecting transverse hole 73. The inner wall of the heat-conducting silicone rubber 71 is arranged with a flow gap 72, and the inside of the top pipe 32 is arranged with a connecting transverse hole 73 in a ring shape.

[0039] The inner wall of the top tube 32 is arranged with annular holes 43, and one side of each annular hole 43 is arranged with a cone 44, and the cone 44 is distributed on the inner wall of the top tube 32 between two transverse heat-conducting silicone rubbers 71;

[0040] During installation, the fitting seat 21 is placed on the upper surface of the base 1, and the terminal extending from the lower end of the fitting seat 21 is plugged into the upper surface of the base 1. At the same time, the two push rods 35 on both sides of the fitting seat 21 are stuck in the conical groove 8, and the push rods 35 are made of rubber. The friction force formed by the push rods 35 and the conical groove 8 is greater than the lifting force of the second spring 39, so the fitting seat 21 can be fixed inside, and the elastic stroke of the first spring 34 is Figure 4 As shown in;

[0041] After the electromagnetic coil 25 has been working for a long time or when it fails, the temperature will soar. The top pipe 32 is sleeved on the outer surface of the electromagnetic coil 25. At the same time, the thermal conductive silicone 71 is used as a temperature transfer medium between the two. The thermal conductive silicone 71 is flexible and non-conductive, so it can fit the outer surface of the electromagnetic coil 25 tightly to achieve effective temperature transfer. The bottom foot 31 and the top pipe 32 transferred by the thermal conductive silicone 71 can provide the device with a temperature extraction function, realize a low-temperature working environment for the electromagnetic coil 25, and provide a cooling function for the electromagnetic coil 25.

[0042] And on the basis of conduction cooling, when the electromagnetic coil 25 exceeds the safe temperature, it causes the internal temperature of the top pipe 32 to be high, and the temperature it conducts is even higher, which will cause a fire inside. When it is transmitted to the inside of the foot 31, it will directly affect the connecting outer pipe 37. Through the material properties of the connecting outer pipe 37, the connecting outer pipe 37 will melt quickly or slowly according to the current temperature. The higher the temperature of the electromagnetic coil 25, the higher the danger. At the same time, the higher the temperature transmitted, the higher the temperature transmitted to the connecting outer pipe 37. The higher the temperature, the faster the melting speed of the connecting outer pipe 37.

[0043] When the connecting outer tube 37 is melted, one end of the two first springs 34 loses support, so that the first spring 34 cannot provide thrust to the cone head, and the friction between one end of the cone head and the small high-pressure tank body 38 is reduced. At this time, the elasticity provided by the second spring 39 is greater than the friction between the cone head and the cone groove 8, which causes the fitting seat 21 to bounce upward due to the elasticity of the second spring 39, and squeeze one end of the cone head back into the transverse groove hole 33, driving the transverse groove hole 33 to move laterally, so that the connecting groove 36 is exactly located at the bottom end of the first through hole 41 and the second through hole 42, so that the two are connected, and the carbon dioxide gas inside the small high-pressure tank body 38 is transported through the first through hole 41 and the second through hole 42, and then transported to the inside of each cone mouth 44 through the annular hole 43, and blows on the outer surface of the electromagnetic coil 25, so as to extinguish the fire through the characteristics of carbon dioxide, and the carbon dioxide passes through the flow gap 72 between each two thermal conductive silica gels 71, so as to play a role of continuous fire extinguishing;

[0044] The melting temperature of the connecting outer tube 37 is used as a trigger condition. The melting temperature of the connecting outer tube 37 is between 80 degrees and 100 degrees. Through the transmission loss of the top pipe 32 and the thermal conductive silicone 71, the electromagnetic coil 25 can melt the connecting outer tube 37 only when the temperature is above 100 degrees. When the electromagnetic coil 25 is above 100 degrees, the surrounding plastic parts will be deformed and a fire will occur. Before the device reaches the critical point of the fire, carbon dioxide is used for blowing and extinguishing. Due to the limitation of the cross partition 22, the interior is in a sealed state, which makes the fire extinguishing effect more significant. In addition, the interior of the device automatically switches according to the current temperature without manual intervention.

[0045] Example 2

[0046] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The first dry powder box 501 has the same internal structure as the second dry powder box 502. The internal structures of the first dry powder box 501 and the second dry powder box 502 are in an inversely symmetrical state. A sealing partition 54 is fixedly installed inside the first dry powder box 501. A fixed tube 52 is provided at one end of the sealing partition 54. A movable tube 51 is slidably installed on the outer side of the fixed tube 52. The movable tube 51 and the fixed tube 52 are used to provide a gas extrusion function. A limiting partition 55 located on both sides of the fitting seat 21 is installed in the lateral middle position of the first dry powder box 501 and the second dry powder box 502. The limiting partition 55 is used to provide a limiting function for the two movable tubes 51.

[0047] A transmission tube 65 is provided at the other end of the sealing partition 54. A nozzle 64 is provided on the upper surface of the first dry powder box 501. The transmission tube 65 is connected to the nozzle 64. The nozzle 64 is inclined and faces the direction of the fitting seat 21.

[0048] A rhombus tube 61 is provided at the upper end of the transmission tube 65, a hollow plate 62 is provided inside the rhombus tube 61, and a dry powder fire extinguishing agent 63 is placed on the upper surface of the hollow plate 62;

[0049] The rhombus tube 61 is a symmetrical conical structure, and the upper end of the rhombus tube 61 is connected to the nozzle 64;

[0050] A third spring 53 is installed on the outer side of the moving tube 51, one end of the third spring 53 is in contact with the outer side of the moving tube 51, and the other end of the third spring 53 is in contact with the outer surface of the sealing partition 54;

[0051] When the interlocking seat 21 rises, the limiting partition 55 is also driven to rise at the same time. The limiting partition 55 is a necessary condition for limiting the moving tube 51 inside the first dry powder box 501 and the second dry powder box 502. When the limiting partition 55 rises, the moving tube 51 is driven to contract by the third spring 53 to compress the internal air. When passing through one end of the fixed tube 52, the port is reduced to increase the air outlet speed and pressure. At the same time, it is transported to the inside of the diamond tube 61 through the transmission tube 65, and the dry powder fire extinguishing agent 63 is blown out from the bottom through the inside of the nozzle 64. The nozzle 64 is inclined toward the interlocking seat 21. The dry powder fire extinguishing agent 63 is powdery. When it is blown out, the dry powder fire extinguishing agent 63 is sprayed toward the interlocking seat 21, scattered in the surrounding air, and slowly falls to the upper surface of the interlocking seat 21 and the transverse partition 22.

[0052] The function of the first dry powder box 501 and the second dry powder box 502 is to add a fire extinguishing insurance operation to the fire if the fire extinguishing effect is not sufficient after the carbon dioxide fire extinguishing operation inside the mating seat 21, so that the first dry powder box 501 and the second dry powder box 502 serve as the above-mentioned conditional insurance measures, so that the device can completely extinguish the fire, thereby achieving double insurance.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
