When the solenoid valve core 2 is separated from the blocking portion 1122, the communication cavity 113 is connected to the circulating portion 1121, that is, the liquid entering from the liquid inlet can be discharged from the liquid outlet. Therefore, on-off control of the electromagnetic valve assembly is conveniently realized.

When the coil 214 is energized, the stationary spool assembly 212 can attract the movable spool assembly 213 from the closed position to the open position. Thus, when the coil 214 is energized, the movable valve element assembly 213 moves to the open position, and the liquid inlet passage 111 and the liquid outlet passage 112 of the solenoid valve body 1 are communicated. When the coil 214 is de-energized, the movable valve core assembly 213 can return to the closed position, so that the liquid inlet passage 111 and the liquid outlet passage 112 of the solenoid valve body 1 are blocked. Therefore, the control of the electromagnetic valve component is realized more simply and conveniently, and the use of the electromagnetic valve component is facilitated.

In some specific embodiments, as shown in fig. 4 and 5, the stationary valve core assembly 212 includes a stationary core 2121, a connector 2123 and a sleeve 2122, the coil 214 is wound around the stationary core 2121, the connector 2123 extends into the communicating chamber 113, a sealing ring is disposed between the connector 2123 and the communicating chamber 113, a portion of the bracket 22 is sandwiched between the connector 2123 and the housing 211, one end of the sleeve 2122 is connected to the stationary core 2121, the other end is connected to the connector 2123, and one end of the movable valve core assembly 213 is slidably disposed in the sleeve 2122. It can be understood that the joint 2123 ensures the connection tightness between the valve core module 21 and the solenoid valve body 1, and the sleeve 2122 defines the moving direction of the movable core 2131, so as to avoid the failure that the movable valve core assembly 213 is tilted during the process of energizing the coil 214, which results in the failure of the solenoid valve assembly to open. The stationary core 2121 can ensure that the stationary core assembly 212 can generate enough magnetic attraction force to suck the movable core assembly 213 back when the coil 214 is energized, thereby ensuring normal opening and closing of the solenoid valve assembly.

In some specific embodiments, as shown in fig. 4-5, the movable core assembly 213 includes a movable core 2131, a sealing member 2132, a first elastic member 2133, a buffering member 2134, and a second elastic member 2135, wherein one end of the movable core 2131 has a boss, the movable core 2131 defines a receiving cavity therein, the sealing member 2132 is connected to one end of the movable core 2131, the sealing member 2132 is configured to close the communicating cavity 113 in the closed position, the first elastic member 2133 is sleeved on the movable core 2131, one end of the first elastic member 2133 is abutted against the boss, the other end of the first elastic member is abutted against the sleeve 2122, and the first elastic member 2133 is configured to drive the movable core 2131 to move from the open position to the closed position.

It can be understood that, in practical use, when the coil 214 is energized, the fixed core 2121 is magnetized to move the movable core 2131 toward the fixed core 2121, the first elastic element 2133 is in a compressed state, and at this time, the sealing element 2132 gradually disengages from the blocking portion 1122, so that the inlet passage 111 of the solenoid valve body 1 communicates with the outlet passage 112. In the process of moving the movable core 2131, the buffering member 2134 firstly impacts the fixed core 2121 to compress the second elastic member 2135, so that the impact of the movable core 2131 on the fixed core 2121 in the switching process of the electromagnetic valve is reduced, and the phenomenon that the fixed core 2121 is damaged in the long-time use process is better avoided. When the coil 214 is de-energized again, the first elastic element 2133 drives the movable core 2131 to move away from the fixed core 2121, so that the sealing element 2132 blocks the blocking portion 1122 again, and at the same time, the movable core 2131 is separated from the fixed core 2121, and the buffer element 2134 extends out of the accommodating cavity under the action of the second elastic element 2135. Therefore, the switch switching function in the practical use of the electromagnetic valve component is well realized.
