[0021] like Figure 1-2 As shown, a magnetic pulse solenoid valve of an embodiment of the present invention includes a shell 1, a first drive component 2 and an electromagnetic coil 3. The shell 1 is internally connected and is provided with an air intake chamber 4, a pressure relief chamber 5 and a diaphragm chamber 6. The diaphragm chamber 6 is located between the outer wall on one side of the air intake chamber 4 and the inner wall of the shell 1 to form a balance channel 7. The balance channel 7 is connected to the air intake chamber 4, and the external compressed air enters the valve body from the air intake chamber 4. The diaphragm chamber 6 is located between the outer wall on one side of the pressure relief chamber 5 and the inner wall of the shell 1 to form a pressure relief channel 8. The pressure relief channel 8 is connected to the pressure relief chamber 5.

[0022] The first drive assembly 2 includes a first magnet 201, a second magnet 202 and a guide rod 203 arranged in the diaphragm chamber 6. The cross-sections of the first magnet 201 and the second magnet 202 are circular. The first magnet 201 is fixed to the diaphragm chamber 6 in a manner including but not limited to bolt connection. One end of the guide rod 203 is fixedly connected to the first magnet 201, and the end face of the second magnet 202 away from the guide rod 203 is fixedly connected to the diaphragm 9 arranged in the diaphragm chamber 6. The magnetic poles of the first magnet 201 and the second magnet 202 are opposite, so that the second magnet 202 is aligned with the first magnet 201. repulsion, so that the second magnet 202 is driven by the first magnet 201 to drive the diaphragm 9 to arch; the electromagnetic coil 3 is arranged above the housing 1, and a second drive component is provided in the electromagnetic coil 3, the second drive component includes a fixed iron core 10 and a moving iron core 11, and the fixed iron core 10 and the moving iron core 11 are connected by a spring 12. The fixed iron core 10 is arranged at a position above the middle of the electromagnetic coil 3, and the moving iron core 11 is arranged below the fixed iron core 10. When the electromagnetic coil 3 is energized or de-energized, the moving iron core 11 is separated from / abutted against the pressure relief channel 8, so that the diaphragm 9 clears or blocks the air inlet chamber 4 and the pressure relief chamber 5.

[0023] The pulse solenoid valve of this embodiment adopts a spring-free structure. Specifically, a first drive component 2 is set in the diaphragm chamber 6, wherein the position of the first magnet 201 is fixed, and the second magnet 202 moves on the guide rod 203 relative to the position of the first magnet 201. At the same time, the second magnet 202 is fixedly connected to the diaphragm 9. When the electromagnetic coil 3 is energized or de-energized, the second magnet 202 drives the diaphragm 9 to move to clear or block the air intake chamber 4 and the pressure relief chamber 5, thereby solving the problem of the pulse solenoid valve malfunction caused by repeated movement and deformation of the spring 12 structure in the pulse solenoid valve.

[0024] like Figure 1 As shown, when a pulse signal is input, the electromagnetic coil 3 is energized, and the moving iron core 11 is moved upward and separated from the pressure relief channel 8. At this time, the pressure in the diaphragm chamber 6 is relieved from the pressure relief channel 8, and the second magnet 202 is under pressure to overcome the repulsive force from the first magnet 201 and drive the diaphragm 9 to arch, so that the air inlet chamber 4 and the pressure relief chamber 5 are unblocked, and the compressed air enters the pressure relief chamber 5 directly from the air inlet chamber 4 through the diaphragm chamber 6. The compressed air passes through instantly, and the center of the second magnet 202 is provided with a hole opposite to the guide rod 203, and the two ends of the guide rod 203 are respectively arranged perpendicular to the first magnet 201 and the second magnet 202. When the second magnet 202 moves under pressure, the guide rod 203 is inserted into the hole, so that the second magnet 202 arches on the guide rod 203 by the depth of the hole, thereby opening the valve.

[0025] like Figure 2As shown, when the pulse signal ends, the electromagnetic coil 3 is de-energized, the moving iron core 11 is reset and abuts against the pressure relief channel 8. At this time, the pressure relief channel 8 is closed, and the pressure in the diaphragm chamber 6 enters from the balance channel 7. The second magnet 202 is not affected by the pressure, but is subjected to the repulsive force of the first magnet 201, so that the second magnet 202 drives the diaphragm 9 to reset. The diaphragm 9 blocks the air inlet chamber 4 and the pressure relief chamber 5 to close the valve, and a sealing gasket 13 is provided at the contact portion between the diaphragm 9 and the pressure relief chamber 5 to improve the sealing effect.

[0026] It is worth noting that the second magnet 202 drives the center of the diaphragm 9 to arch upward, thereby making the diaphragm 9 break away from the blocking effect on the air inlet chamber 4 and the pressure relief chamber 5, and the guide rod 203 does not pass through the sealing gasket.

[0027] In another embodiment, the gap space between the diaphragm 9 and the diaphragm chamber 6 is filled with a damping sponge 14. When the diaphragm 9 moves, the damping sponge 13 provides cushioning, so that the diaphragm 9 is evenly stressed during repeated movements, thus avoiding damage.

[0028] 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 replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
