As shown in fig. 1 to 3, the electromagnetic valve manual switch structure of the embodiment of the utility model comprises a valve body 1, an on-off control module, an electric driving module and a manual driving module.
Specifically, as shown in fig. 1, the valve body 1 is provided with an air inlet 11 and an air outlet 12, and the air inlet 11 and the air outlet 12 are mutually communicated and are respectively used for air inlet and air outlet.
Specifically, as shown in fig. 1, an on-off control module is connected to the valve body 1, and is used for controlling on-off of the air outlet 12 and the air inlet 11. The on-off control module comprises: the connecting piece 21, the two sealing pieces 22, the rubber gasket 23, the first spring 24, the movable iron core 25 and the second spring 26. The connecting piece 21 is connected with the top of the valve body 1, and two through holes are formed in the connecting piece 21; the two sealing elements 22 are respectively arranged in the through holes, and the top and the bottom of any sealing element 22 penetrate through the two ends of any through hole; the rubber gaskets 23 are arranged at the bottoms of the two sealing pieces 22, block the air inlet 11 and are used for controlling the on-off of the air outlet 12 and the air inlet 11; a first spring 24 is provided between the valve body 1 and the two seals 22 for providing elastic force; the movable iron core 25 is arranged on the top of the connecting piece 21, and the movable iron core 25 is arranged on the top of the two sealing pieces 22; the second spring 26 is sleeved at the bottom of the movable iron core 25, and the second spring 26 is a cone spring and is used for providing elastic force, and the elastic force of the second spring 26 is larger than that of the first spring 24.
Specifically, as shown in fig. 1, the electric driving module is connected with the on-off control module and is used for electrically controlling the on-off control module. The electric drive module includes: stationary core assembly 31 and electromagnetic coil 32. The static iron core assembly 31 is arranged at the top of the connecting piece 21, and the static iron core assembly 31 covers the movable iron core 25; the electromagnetic coil 32 is connected to the stationary core assembly 31.
Specifically, as shown in fig. 2-3, the manual driving module is connected with the on-off control module and is used for manually controlling the on-off control module. The manual driving module comprises: guide sleeve 41, ejector pin 42, third spring 43, push rod 44, and button 45. The guide sleeve 41 is embedded in the connecting piece 21; one end of the ejector rod 42 is connected with one end of the guide sleeve 41, and the other end of the ejector rod 42 is contacted with the movable iron core 25 and used for ejecting the movable iron core 25; the third spring 43 is sleeved on the ejector rod 42; one end of the push rod 44 is connected with the other end of the guide sleeve 41, and a retaining ring 442 and an elastic retaining ring 441 are arranged between the push rod 44 and the inner wall of the connecting piece 21; a button 45 is provided at the other end of the push rod 44.
