[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3In the embodiment of the present invention, a pulse switch with a special-shaped spring 40 includes a valve stem 20, a valve needle 30, a valve core 10, a special-shaped spring 40 and a pulse sheet 16. The valve core 10 has a hollow body running through the upper and lower ends. The valve needle 30 is inserted into the hollow body. The upper end of the valve needle 30 is provided with a first blocking ring 12, and the hollow body is provided with a second blocking ring 31. The special-shaped spring 40 is sleeved on the valve needle 30, and the lower end of the special-shaped spring 40 abuts against the second blocking ring 31. At the upper end, the upper end of the special-shaped spring 40 abuts against the lower end of the first blocking ring 12; the lower end of the valve stem 20 is provided with an external connection portion 21, and the upper end of the valve core 10 is provided with an internal connection portion 11, the external connection portion 21 and the internal connection portion 11 are slidably connected to each other, and the upper end of the valve needle 30 abuts against the lower end of the valve stem 20; the pulse plate 16 is installed on the side of the valve core 10, and the upper end of the special-shaped spring 40 extends outward with a downward pressure support foot 41, and the lower end of the downward pressure support foot 41 cooperates with the pulse plate 16.

[0019] By utilizing the special-shaped spring 40, the circuit is turned on through the contact between the downward pressing leg 41 on the special-shaped spring 40 and the pulse plate 16. The downward pressing of the valve stem 20 drives the valve needle 30 downward, and at the same time, the valve needle 30 presses down the upper end of the special-shaped spring 40 to compress the special-shaped spring 40.
