Solenoid valves can achieve the desired control by coordinating with different circuits to ensure control accuracy and flexibility.

A temperature sensor 10 is connected to the bottom of the fixed iron core 6. Figure 3It can be seen that the bottom end of the movable push rod 9 is connected with a sealing plug, and the top end of the sealing plug is connected with a return spring. This is a conventional setting of the current solenoid valve, so it is not repeated in the specification. The temperature sensor 10 is used to detect the temperature of the coil 5. The top end of the fixed frame 3 is connected with an outer baffle 46, which has a certain strengthening effect. The inner side of the outer baffle 46 is connected with a fan blade assembly 11 between the core frame 4, and the outer surface of the outer baffle 46 is connected with a sealing chamber 12. The sealing chamber 12 is filled with insulating non-corrosive liquids such as perfluoropolyether, electronic fluorinated liquid or deionized water to cool the variable magnetic assembly 13.

The other end of the air intake pipe 16 is connected to the inside of the core frame 4. A branch pipe 17 is connected to the top of the air intake pipe 16. A partition 18 is connected to the top of the branch pipe 17.

[0033] Reference Fig.10 As shown, the blocking mechanism 21 includes a connecting frame 211, which is connected to the connecting mechanism 20 through the connecting frame 211 to complete the installation. The top of the connecting frame 211 is connected to a flaring frame 213 to increase the overall protection volume of the blocking mechanism 21. A rotating frame 212 is rotatably arranged below one side of the flaring frame 213. A ventilation frame 214 is connected to the top of the flaring frame 213. A ventilation hole of the same size as the baffle 216 is opened on one side of the ventilation frame 214. A sliding hole 215 is opened on the top of the flaring frame 213. The baffle 216 is slidably connected to the ventilation frame 214 through the sliding hole 215. A connecting bolt 217 is connected to one side of the baffle 216. A guide hole 219 is opened on one side of the rotating frame 212. The connecting bolt 217 is slidably connected to the guide hole 219.

Figure 2As shown, two micro motors 22 are connected to the top of the valve body 1, and the output ends of the micro motors 22 are connected to drive gears 23. One side of the drive gear 23 is meshed with the rack rail 218. The micro motor 22 drives the drive gear 23 to rotate, and drives the rotating frame 212 to rotate through the meshing with the rack rail 218. When the rotating frame 212 rotates, the connecting bolt 217 is driven to move up and down through the guide hole 219 on one side, thereby driving the baffle 216 to move through the slide hole 215, blocking the air holes on one side of the air frame 214 to form a sealing cover, which has a protective effect. A wire clamping groove is opened at the top of one group of air holes corresponding to the power connection component 19. When the blocking mechanism 21 is combined, the wire of the power connection component 19 can be pushed and clamped into the wire clamping groove;

[0034] Reference Figure 6 As shown, the cooling component 14 includes a circulating air pipe 141 fixedly arranged on one side of the outer baffle frame 46 and a fixed slot frame 142 fixedly arranged on one side of the outer baffle frame 46, a chimeric frame 143 is connected to the inner side of the fixed slot frame 142, a cooling plate 144 is connected to one side of the chimeric frame 143, wherein the cooling surface of the cooling plate 144 faces inward and the heat release surface faces outward, a heat dissipation frame 145 is connected to one side of the fixed slot frame 142 to accelerate the heat dissipation effect of the heat release surface of the cooling plate 144, one end of the circulating air pipe 141 is connected to the outer baffle frame 46, when exhausting in the outer baffle frame 46, part of the gas can enter the circulating air pipe 141, and then be discharged through the air outlet slot 146 The air outlet slot 146 is connected to one side of the inner wall thereof with an inclined plate 147, which plays a certain guiding effect. The air outlet slot 146 is located above the heat sink 145, which can effectively increase the heat dissipation effect of the heat sink 145. The top of the fixed slot frame 142 is connected to the air inlet frame 15, and the top of the air inlet frame 15 is provided with an expanded slot 151. The top of the fixed slot frame 142 is provided with a through hole corresponding to the expanded slot 151. External air can pass through the expanded slot 151 and enter the fixed slot frame 142 through the through hole, and is cooled by the refrigeration plate 144 to form low-temperature air. The low-temperature air then enters the air inlet pipe 16. The expanded slot 151 is filled with a dehumidification layer to prevent external dust from entering.

[0035] Reference Figure 4 The fan blade assembly 11 shown has two groups, which are arranged up and down. A heat sink 44 is connected to one side of the core frame 4. The heat sink 44 can absorb and dissipate the heat of the coil 5 in the core frame 4. The heat sink 44 is located between the two groups of fan blade assemblies 11. When the lower fan blade assembly 11 is working, the heat dissipation effect of the heat sink 44 can be accelerated.

[0036] Reference Figure 5As shown, the core frame 4 includes a coil mounting frame 41, an insulating frame 411 is connected to the inside of the coil mounting frame 41, the coil 5 is wound and arranged on the surface of the insulating frame 411, the fixed iron core 6 is connected and arranged inside the insulating frame 411, and a guide plate 45 is connected to the outer surface of the coil mounting frame 41. When the two groups of fan blade assemblies 11 are working, the guide plate 45 can provide a guiding effect, so that air is discharged through the exhaust hole 451. One side of the guide plate 45 is fixedly connected to the outer baffle frame 46, and a plurality of exhaust holes 451 are opened at the top. The outer ring of the coil mounting frame 41 is provided with a plurality of exhaust holes 43, and the corresponding exhaust holes 43 are connected to the baffle plate 431. After being cooled by the refrigeration plate 144, Air enters the coil mounting frame 41 through the air inlet pipe 16, and part of the air enters the area between the outer baffle frame 46 and the core frame 4 through the branch pipe 17. The low-temperature air entering the coil mounting frame 41 takes away the heat generated by the coil 5 and then is discharged through the exhaust hole 43. When the fan blade assembly 11 is working, wind is discharged through the exhaust hole 451, thereby forming a negative pressure at the mouth of the exhaust hole 43, accelerating the discharge of air in the coil mounting frame 41. The baffle 431 effectively prevents the air from flowing back into the coil mounting frame 41 through the exhaust hole 43. At the same time, when the fan blade assembly 11 is working, negative pressure will be formed at the bottom, accelerating the entry of cold air through the branch pipe 17, and effectively dissipating heat and cooling.

[0037] Reference Fig. 9 As shown, the fan blade assembly 11 includes a limit frame 114 fixedly mounted on one side of the inner wall of the outer retaining frame 46, and a spoiler blade 112 is rotatably arranged inside the limit frame 114. The outer ring of the spoiler blade 112 is connected to a plurality of magnetic blocks 113, and the inner ring of the spoiler blade 112 is rotatably arranged with a connecting kit 111, which is rotatably connected to the core frame 4. The variable magnetic assembly 13 includes a stator frame 131 fixedly mounted on one side of the inner wall of the sealing chamber 12, and a winding frame 132 is connected to one side of the inner wall of the stator frame 131. A variable magnetic coil 133 is wound on the surface of the winding frame 132, and the through hole controls the direction of the current passing through 133 to change the magnetism, thereby attracting the magnetic block 113 to drive the spoiler blade 112 to rotate. A position encoder is provided in the limit frame 114, and this current sensor is connected to the variable magnetic assembly 13. In conjunction with an additional controller or control chip, the fan blade assembly 11 can be driven to work by the variable magnetic assembly 13 when power is turned on. Because it is an existing mature technology, it is not described in detail in the specification.

[0038] Reference Figure 3 and Figure 7As shown, the power connection component 19 includes a shell 190, a circuit board 191 is connected to the shell 190, a wire is connected to one side of the circuit board 191, and a voltage regulator 194 is connected to the shell 190. When the overall temperature of the device is too high, the voltage regulator 194 adjusts the input voltage to reduce the overall power and avoid power accidents. A reverse diode 192 is connected to one side of the circuit board 191 to control the current and protect the internal power consumption. The control chip 193 is used for automatic adjustment of the voltage regulator 194, and the voltage regulator 194 is electrically connected to the circuit board 191.

[0039] Reference Figure 5 As shown, a plurality of co-flow holes 25 are provided on one side of the outer baffle 46, and the insulating liquid in the sealed chamber 12 flows into the sealed area below the partition 18 through the co-flow holes 25, further increasing the low temperature range.

[0040] Reference Figure 2 and Figure 8 As shown, the connection mechanism 20 includes a mounting seat 201 fixedly arranged at the bottom side of the top end of the valve body 1, and a threaded frame 202 is connected to the top end of the mounting seat 201, and the threaded frame 202 is threadedly connected to the connecting frame 211. Figure 2 As shown, a sealing ring is provided at the top of the mounting seat 201 , and when the connecting frame 211 rotates to the bottom of the threaded frame 202 , the sealing ring will be pressed against to increase the sealing performance.

[0041] The implementation principle of the present application is as follows: the device is connected to an external power source through the power connection component 19, the coil 5 is energized to control the up and down movement of the movable top rod 9, and the overall closed switch is controlled. When the temperature sensor 10 detects that the internal temperature has risen, the variable magnetic component 13 is energized to drive the fan blade component 11 to start, and the internal hot air is blown out through the exhaust hole 451 to cool the interior and discharge heat. When the fan blade component 11 blows air, a negative pressure is formed at the bottom of the fan blade component 11, and the air in the intake pipe 16 is extracted through the branch pipe 17. At the same time, a negative pressure is formed at the outer mouth of the exhaust hole 43 during exhaust, thereby extracting the hot air inside the coil mounting frame 41, and extracting the hot air in the fixed slot frame 142 through the intake pipe 16. The outside air enters the fixed slot frame 142 through the expanded slot 151, and is converted into low-temperature air by the refrigeration sheet 144, and enters the coil mounting frame 41 to cool the coil 5. While the air is discharged through the exhaust hole 451, part of the air enters the circulating air pipe 141 and is discharged through the air outlet slot 146 to dissipate heat for the heat dissipation frame 145. When the device is damaged under unexpected circumstances or electric sparks are accidentally generated inside due to electricity use, the micro motor 22 drives the driving gear 23 to rotate, so that the sealing mechanism 21 is merged, and the power end of the device is completely sealed to prevent electric sparks or arcs from contacting the external environment. At the same time, when an accidental internal explosion occurs, the environmental safety can also be protected.
