The following is a specific embodiment of the present invention, and the technical solution of the present invention will be further described with reference to fig. 1 to 4, but the present invention is not limited to this embodiment.
As shown in fig. 3, the present invention proposes a spring 40, where the spring 40 is circular, and a first through hole 41 is disposed in the middle of the spring 40. The elastic sheet 40 is provided with an outer ring waist-shaped hole 42 and an inner ring waist-shaped hole 43 concentric with the first through hole 41 at the edge of the first through hole 41. Two circles of waist-shaped holes are arranged on the outer side of the first through hole 41, so that materials can be saved, and the size, shape and position of the waist-shaped holes can be changed according to requirements, so that the elastic force curve generated by the elastic sheet 40 can be adjusted.
Further, the gaps between two adjacent outer ring kidney-shaped holes 42 correspond to the positions of the inner ring kidney-shaped holes 43, and the first through hole 41, the first ring surrounded by the plurality of inner ring kidney-shaped holes 43, and the second ring surrounded by the plurality of outer ring kidney-shaped holes 42 are coaxially arranged. This arrangement makes the spring force curve generated by the spring 40 smoother.
Further, the spring 40 is made of SUS301 stainless steel, and the spring 40 is processed by milling or punching. SUS301 contains lower nickel, chromium and higher carbon components than SUS304, and can achieve high strength by cold working. SUS301 has excellent high temperature strength, fatigue resistance and corrosion resistance compared with common steel, so that the elastic sheet 40 has the advantages of light weight and high strength.
As shown in fig. 1, the present invention proposes a nonlinear force generating structure comprising: coil 10, movable iron core 20, locating part 30 and shell fragment 40.
The coil 10 can produce the magnetic field after the circular telegram, move iron core 20 and include first tip 21 and iron core body 22, first tip 21 with iron core body 22 is the cylinder, first tip 21 with iron core body 22 connects, first tip 21 set up in shell fragment 40 is kept away from one side of locating part 30, iron core body 22 set up in the opposite side of shell fragment 40, first tip 21 with shell fragment 40 supports to lean on the cooperation, iron core body 22 inserts and locates in the coil 10, shell fragment 40 passes through first through-hole 41 cover is located on the iron core body 22. Providing the core body 22 in the coil 10 can increase the magnetic flux of the coil 10, thereby increasing the electromagnetic force of the coil 10 to the movable core 20.
Further, the elastic piece 40 is integrally provided with the first end 21, and the deformation state of the elastic piece 40 in the moving process can be better controlled by integrally providing the elastic piece 40 with the first end 21.
The bottom of the limiting piece 30 is provided with a limiting surface 31, and the limiting surface 31 can play a limiting role when the elastic piece 40 deforms. The stopper 30 has a second through hole 32, and the moving core 20 sequentially passes through the first through hole 41 and the second through hole 32. As shown in fig. 2, the elastic piece 40 is limited during deformation, so that the elastic force generated during deformation of the elastic piece 40 and the displacement of the movable iron core 20 have a nonlinear relationship. Since the limiting member 30 has the limiting surface 31, the elastic sheet 40 is limited during deformation, so that the elastic force generated by the elastic sheet 40 during deformation and the displacement of the movable iron core 20 are in a nonlinear relationship.
Further, as shown in fig. 1 and 4, the intersection line of the limiting surface 31 and the longitudinal section of the limiting member 30 is an arc line or a straight line. So arranged, the curve of the elastic force of the elastic sheet 40 and the displacement of the movable iron core 20 can be adjusted by adjusting the shape of the limiting surface 31.
Further, the height of the limiting surface 31 is smaller than the difference between the radius of the elastic sheet 40 and the radius of the first through hole 41. The arrangement is such that the deformation of the spring 40 is not excessive, and the spring 40 is prevented from breaking or deforming irrecoverably.
Further, the preferred material of the limiting member 30 is brass, and the brass has an electromagnetic shielding function as a metal, which makes the limiting member 30 function as a magnetism isolating sleeve in addition to the limiting function, the limiting member 30 has a second through hole 32 in the middle, and the limiting member 30 makes the magnetic field generated by the coil 10 have an electromagnetic force on the movable iron core 20 only through the second through hole 32.
The invention also provides an electromagnetic valve comprising the nonlinear force generating structure. Since the movable iron core 20 is simultaneously subjected to the action of electromagnetic force and elastic force, and the electromagnetic force and the displacement of the movable iron core 20 are in a nonlinear relationship, specifically, the electromagnetic force of the coil 10 to the movable iron core 20 and the square of the distance between the movable iron core 20 and the coil 10 are inversely proportional to each other, and simultaneously are directly proportional to the square of the current of the coil 10, when the limiting surface 31 of the limiting piece 30 is matched with the elastic piece 40, the relationship between the elastic force of the elastic piece 40 and the displacement of the movable iron core 20 is close to the relationship between the electromagnetic force generated by the coil 10 and the displacement of the movable iron core 20, so that the electromagnetic valve can be opened more stably and the opening degree of the electromagnetic valve is controlled accurately.

Preferably, the first end 21 has a protrusion 25, the valve core 60 is sleeved on the protrusion 25, and the valve core 60 is in interference fit with the protrusion 25. Because the valve core 60 is sleeved on the protrusion 25 and the valve core 60 is in interference fit with the protrusion 25, the valve core 60 has good sealing performance.
The electromagnetic valve further comprises a static iron core 70, wherein the static iron core 70 is arranged near the iron core body 22, and the static iron core 70 is inserted into the coil 10. The stationary core 70 is provided in the coil 10, and the magnetic flux of the coil 10 can be increased, thereby increasing the electromagnetic force of the coil 10 to the movable core 20.
The electromagnetic valve further comprises a diaphragm 80 and a sealing ring 90, wherein the diaphragm 80 is sleeved on the valve core 60, the diaphragm 80 is abutted against the first end part 21, and the sealing ring 90 is sleeved on the iron core body 22. The first end 21 is provided with a vent hole 23, and the vent hole 23 communicates with the valve core 60.
When the electromagnetic valve is not energized, the air flowing into the air inlet 51 passes through the valve core 60 and enters the chamber from the air vent 23, the air pressure in the chamber is increased, and the spring 40 is assisted by the high-pressure air in the chamber to seal the valve port 61.

The working process of the electromagnetic valve is as follows:
1. when the electromagnetic valve is not electrified, gas enters from the air inlet 51, the gas passes through the valve core 60 and the vent holes 23 and enters the cavity, and at the moment, the valve port 61 is closed due to the pressure difference between the gas in the cavity and the external gas and the action of the elastic sheet 40;
