[0046] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.
[0047] Please refer to Figures 1-3 The self-adaptive structure jump block 100 and the electromagnetic valve 1000 provided in the embodiments of the utility model can solve the above problems, which will be described in detail.
[0048] The self-adaptive structure jump block 100 is applied to the electromagnetic valve 1000, which comprises a jump head 110 and a jump seat 120;
[0049] The jump seat 120 is provided with a first through hole 121, the jump head 110 is connected to the center position of one end of the jump seat 120, and the end of the jump head 110 away from the jump seat 120 is formed with a ball head 111, which is used for sealing the valve port 810 of the piston 800 in the inclined state.
[0050] In the working process, the first through hole 121 is used to realize the air flow communication between the two ends of the bumping seat 120. When the inclination occurs, even if the bumping seat 120 and the bumping head 110 are inclined, the sealing effect on the valve port 810 can still be maintained through the ball head 111 to realize the self-adaptive sealing of the valve port 810, thereby avoiding the problem of leakage of the valve port 810.
[0051] In the embodiment, the cross section of the first through hole 121 is circular. Of course, in other embodiments of the utility model, the cross section of the first through hole 121 can also be rectangular, prismatic, triangular, sectorial or other shapes, and the specific cross section shape is not limited.
[0052] Moreover, the number of the first through hole 121 can be one or multiple. When the number of the first through hole 121 is multiple, the multiple first through holes 121 can be uniformly arranged along the central axis of the bumping seat 120 in a ring shape.
[0053] Referring to Figure 1 , Figure 3 and Figure 4 , the edge of the end of the bumping seat 120 away from the bumping head 110 is formed with a ring-shaped arc surface 122. The ring-shaped arc surface 122 is used to move in the bumping cavity 320 in the inclined state, and the end of the first through hole 121 away from the bumping head 110 is located on the inner side of the ring of the ring-shaped arc surface 122.
[0054] When the inclination occurs, because of the existence of the ring-shaped arc surface 122, the distal end of the bumping seat 120 can be adaptively rotated to a certain extent to resist the negative effects brought by the inclination. Moreover, the distal end of the first through hole 121 is located on the inner side of the ring of the ring-shaped arc surface 122 to avoid the shielding of the distal end of the first through hole 121 in the inclined state, thereby preventing the negative effects on the air flow between the two ends of the bumping seat 120.
[0055] It is worth noting that the distal end can be understood as the end away from the valve port 810, and the proximal end can be understood as the end close to the valve port 810.
[0056] Referring to Figure 1 , Figure 3 and Figure 4 , in order to reduce the contact area between the bumping seat 120 and the bumping cavity 320, a recess groove 123 can be formed on the end of the bumping seat 120 away from the bumping head 110. The recess groove 123 is in communication with the first through hole 121, and the recess groove 123 is located on the inner side of the ring of the ring-shaped arc surface 122.
[0057] In the embodiment, the cross section of the recessed groove 123 is circular; of course, in other embodiments of the utility model, the cross section of the recessed groove 123 can also be rectangular, prismatic, triangular, sectorial or other shapes, and the specific cross section shape is not limited.
[0058] With reference to Figure 2 、 Figure 3 and Figure 5 , the edge of the far end of the rebound seat 120 from the rebound head 110 is formed with a spherical arc surface 124, the spherical arc surface 124 is used to move in the rebound cavity 320 in the inclined state, and the first through hole 121 is arranged on the spherical arc surface 124 away from the rebound head 110.
[0059] It is worth noting that when the far end of the rebound seat 120 is the spherical arc surface 124, it has stronger adaptability relative to the annular arc surface 122, that is, in the inclined state, the movement range of the spherical arc surface 124 in the rebound cavity 320 can be larger.
[0060] With reference to Figures 3-6 , the embodiment of the utility model also provides an electromagnetic valve 1000, which comprises:
[0061] a static iron core body 200, a moving iron core body 300, a sleeve pipe 400, a valve cover 920, a first elastic piece 500, a piston 800, a support seat 600, a second elastic piece 700 and a rebound block 100 with an adaptive structure;
[0062] The static iron core body 200 is used to be adsorbed and matched with the moving iron core body 300 in the electrified state, the sleeve pipe 400 is simultaneously sleeved on the static iron core body 200 and the moving iron core body 300, the valve cover 920 is sleeved on the sleeve pipe 400, the first elastic piece 500 is abutted between the valve cover 920 and the moving iron core body 300, the moving iron core body 300 is formed with a rebound cavity 320 away from the static iron core body 200, the rebound seat 120 is movably accommodated in the rebound cavity 320, and the piston 800 is arranged with a valve port 810.
[0063] The spherical head 111 is used to seal the valve port 810 in the inclined state, the support seat 600 is sleeved on the end of the piston 800 close to the spherical head 111, and the second elastic piece 700 is connected between the rebound seat 120 and the support seat 600.
[0064] In the valve opening process, the static iron core body 200 is electrified to drive the moving iron core body 300 to move a first stroke first, in this process, only the first elastic piece 500 needs to be overcome without needing to overcome the differential pressure force around the valve port 810, so that the spherical head 111 movably accommodated in the rebound cavity 320 continues to seal the valve port 810, and the moved moving iron core body 300 will be subjected to a stronger electromagnetic force because it is closer to the static iron core body 200, thereby overcoming the differential pressure force to make the spherical head 111 open the valve port 810.
[0065] It is worth noting that by forming the jump cavity 320 in the moving iron core body 300 and enabling the jump head 110 and the jump seat 120 to move in the jump cavity 320, and without overcoming the pressure difference force when the static iron core body 200 attracts the moving iron core body 300 to move the first stroke, the moving iron core body 300 can be moved, a stronger electromagnetic force is generated when the moving iron core body 300 approaches the static iron core body 200, and then the pressure difference force is overcome to open the valve port 810, thereby improving the valve opening capacity.
[0066] Reference Figures 7-12 In the unpowered state, i.e. when the static iron core body 200 does not generate an electromagnetic force to move the moving iron core body 300, the distance between the moving iron core body 300 and the static iron core body 200 is H1, and at this time the support seat 600 is spaced apart from the jump block 100 with an adaptive structure and the distance is H2, H2
[0067] During the first stroke of the moving iron core body 300, the support seat 600 moves synchronously with the moving iron core body 300, and the second elastic member 700 is compressed during the movement until the support seat 600 abuts against the jump block 100 with an adaptive structure, and because the pressure difference force is not overcome during this process, the jump block 100 with an adaptive structure does not change position and continues to seal the valve port 810. During this process, the length of the first stroke is H2, i.e. the displacement of the moving iron core body 300 and the limit block is H2, the distance between the moving iron core body 300 and the static iron core body 200 is H1-H2, and the jump cavity 320 of the moving iron core body 300 and the jump block 100 with an adaptive structure have a distance H2.
[0068] When the moving iron core body 300 moves the first stroke, it is closer to the static iron core body 200, so it receives a larger electromagnetic force and has a stronger valve opening capacity. At this time, the electromagnetic force overcomes the pressure difference force near the valve port 810, and the moving iron core body 300 continues to move the second stroke towards the static iron core body 200, and the length of the second stroke is H1-H2, i.e. the displacement of the moving iron core body 300, the jump block 100 with an adaptive structure and the support seat 600 is H1-H2, and after moving, the moving iron core body 300 is in contact with the static iron core body 200. And during this process, the jump block 100 with an adaptive structure moves away from the valve port 810 to open the valve port 810 and complete the valve opening action.
[0069] Reference Figure 3 and Figures 7-12The support seat 600 comprises a seat body 610 and a support ring 620 connected with each other, the seat body 610 is connected to the outer side of the support ring 620, the second elastic member 700 is sleeved on the support ring 620 and connected to the seat body 610, and the support ring 620 is sleeved on one end of the piston 800 close to the ball head 111.

[0071] When the valve port 810 is opened, the piston 800 can also move towards the direction close to the static iron core body 200, so that the inlet 931 and the outlet 932 of the piston 800 are communicated, and the moving stroke of the piston 800 is H3, H3
[0072] Reference Figures 7-12 In order to realize the air pressure balance between the bump cavity 320 and the external space, the third through hole 310 is arranged on one end of the moving iron core body 300 close to the piston 800, and the third through hole 310 is communicated with the bump cavity 320. In the embodiment, the third through hole 310 is arranged in the radial direction of the moving iron core body 300.
