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.

[0025] See also Figure 1-3 The utility model provides a technical solution: an electromagnetic pulse valve with good sealing effect, comprising a valve body 10, an air inlet 20 arranged on one side of the valve body 10, an air outlet 30 arranged at one end of the valve body 10, a connecting body 50 arranged at the other end of the valve body 10 and a pulse controller 60 arranged at one end of the connecting body 50, a pulse component and a sealing component are arranged inside the valve body 10, the pulse component comprises a compression spring 72 arranged inside the connecting body 50, an armature 73 is arranged at one end of the compression spring 72, and a diaphragm 74 is arranged at one end of the armature 73, the pulse component also comprises two groups of electromagnetic coils 71 arranged inside the connecting body 50, and the sealing component comprises a fixing ring 90 arranged inside the valve body 10, a plurality of supporting springs 91 arranged at the bottom of the fixing ring 90, a supporting ring 92 arranged at the bottom of the fixing ring 90, and a baffle 93 arranged on one side of the supporting ring 92.

[0026] It should be noted that the pulse controller 60 is one of TKZM-12, TKZM-08, and WMK-4. The utility model uses the pulse controller 60 to realize power-off and power-on of the electromagnetic coil 71, and uses the magnetic field to move the armature 73 up and down. This technology is well known in the prior art, so its specific structure and working principle are not repeated in this solution.

[0027] Among them, an air inlet hole 40 is opened on one side of the valve body 10, and the air inlet hole 40 is connected with the air inlet port 20. The air inlet hole 40 is circular in design. The air inlet hole 40 can be closed by using a baffle 93 to prevent the gas from flowing into the interior of the valve body 10 from the air inlet hole 40 after the device is closed, thereby improving the sealing effect.

[0028] At the same time, a guide tube 70 is provided inside the connecting body 50 , and the compression spring 72 is located inside the guide tube 70 , which can guide the compression spring 72 and prevent the compression spring 72 from bending.

[0029] See also Figure 2-3 A sealing gasket 94 is provided on one side of the baffle 93. The sealing gasket 94 is made of rubber. The sealing gasket 94 is inserted into the air inlet hole 40 and fits with the gap of the air inlet hole 40. The sealing gasket 94 has a certain elasticity to facilitate insertion into the air inlet hole 40 or withdrawal from the air inlet hole 40. At the same time, the air inlet hole 40 can be blocked to prevent gas from flowing in and improve air tightness.

[0030] It should be understood that the outer wall of the armature 73 is provided with four fixed blocks 75, the armature 73 is designed as a cylinder, the four fixed blocks 75 are evenly distributed around the circle, one side of the support ring 92 is provided with four support blocks 95 evenly distributed around the circle, one side of the four fixed blocks 75 is tightly fitted with one side of the four support blocks 95 respectively, and a plurality of support springs 91 are evenly and evenly distributed around the circle. When the power is off, the support springs 91 can push the support block 95 to press the fixed block 75 down. When the power is on, the support block 95 can be pushed up by the fixed block 75, thereby driving the baffle 93 to move upward.

[0031] See also Figure 4 A column 80 is provided inside the valve body 10, an air outlet 81 is provided on one side of the column 80, a groove 82 is provided on one side of the column 80, one end of the air outlet 81 is connected to the air outlet port 30, and the other end of the air outlet 81 is connected to the groove 82. The diaphragm 74 is inserted into the groove 82 and cooperates with the gap therein. The diaphragm 74 is inserted into the groove 82 to close the air outlet 81 and achieve a closing effect.

[0032] Specifically, the working principle of the electromagnetic pulse valve with good sealing effect is:

[0033] The pulse controller 60 cuts off the power to the electromagnetic coil 71, and the armature 73 is not affected by the magnetic field and thus moves downward, so that the diaphragm 74 is inserted into the groove 82 to seal the air outlet 81. In addition, the sealing gasket 94 moves downward under the action of the support spring 91 and is inserted into the air inlet 40 to seal it, thereby preventing gas from flowing in from the air inlet 20 to improve the sealing effect. At the same time, the support block 95 applies downward pressure to the fixing block 75, so that the diaphragm 74 can be fixed in the groove 82, further improving the sealing effect.

[0034] When the pulse controller 60 energizes the electromagnetic coil 71, the armature 73 is moved upward by the magnetic field, and the diaphragm 74 is pulled out from the groove 82. During the upward movement of the armature 73, the fixed block 75 pushes the support block 95 to move upward, and drives the baffle 93 to move upward, and at the same time, the sealing gasket 94 is pulled out from the air inlet 40. At this time, the gas enters the valve body 10 from the air inlet 20, and is finally discharged from the air outlet 30.

[0035] It should be noted that the specific models and specifications of the valve body 10, pulse controller 60, electromagnetic coil 71, armature 73, and diaphragm 74 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
