Referring to fig. 2, the solenoid valve body 2 includes an electromagnet portion 21 and an electrically controlled valve core 22, and the electromagnet portion 21 is powered on to control the electrically controlled valve core 22 to move upward. The solenoid valve body 2 of this structure is prior art and will not be described in detail here.

As shown in fig. 3, the water inlet flow path 11 communicates with the main valve attachment chamber 13 via the main inlet port 31, the main valve attachment chamber 13 communicates with the water outlet flow path 12 via the main outlet port 32, the main valve attachment chamber 13 is provided with the solenoid valve body 2 for normally blocking the flow path between the main inlet port 31 and the main outlet port 32, and the flow path between the main inlet port 31 and the main outlet port 32 is switched between the closed state and the open state by the solenoid valve body 2. Specifically, the flow path between the main inlet and the main outlet of the solenoid valve body is switched between an on state and an off state by an on-off driving power supply, and when the solenoid portion 31 is not energized to operate in a specific application, the electrically controlled valve element 32 abuts against the peripheral edge 321 of the main outlet 32. The main outlet 32 is blocked by the electric control valve core 32 to form a closed state, so that the fluid in the water inlet channel 11 cannot flow into the water outlet channel 12 through the main outlet 32, namely, a blocking state; when the electromagnet portion 31 is energized to operate, the electric control valve element 32 is controlled to move upward, the electric control valve element 32 is separated from the peripheral edge of the main outlet 32, and the main outlet 32 is opened, so that the fluid in the water inlet channel 11 flows into the water outlet channel 12 through the main valve assembling chamber 13, i.e., the connection state.

It should be noted that when the electromagnet portion 31 is not energized, the electrically controlled valve core is normally pressed against the peripheral edge 321 of the main outlet 32 by the compression spring in the structure of the electromagnetic valve body 2, so as to form a normally blocked state.

As shown in fig. 3, an auxiliary valve mounting chamber 14 is further provided in the valve body 1, the water inlet passage 11 communicates with the auxiliary valve mounting chamber 14 through an auxiliary inlet 33, the auxiliary valve mounting chamber 14 communicates with the water outlet passage 12 through an auxiliary outlet 34, the auxiliary valve mounting chamber 14 is provided with an auxiliary valve body 4, and the flow path between the auxiliary inlet 33 and the auxiliary outlet 34 is switched between an on state and an off state by the auxiliary valve body 4.

In one embodiment, the sub-valve body 4 includes a valve core seat 41, a front end 411 of the valve core seat 41 is inserted into the sub-valve assembly chamber 14, and a rear end of the valve core seat 41 is provided with a sealing ring to form a sealing fit with the sub-valve assembly chamber 14. The front end 411 of the valve seat 41 is in sealing fit with the peripheral edge 341 of the secondary outlet 34, the internal channel 401 of the valve seat 41 is communicated with the secondary outlet 34, the cavity 402 formed by the outer side surface of the valve seat 41 and the inner wall of the secondary valve assembly cavity 14 is communicated with the secondary inlet 33, the side wall of the valve seat 41 is provided with a through hole 413 for communicating the internal channel 401 and the cavity 402, and a valve core assembly is arranged in the valve seat 41 for opening and closing the through hole 413. In a specific application, the fluid flows from the water inlet channel 11 to the water outlet channel 12 through the secondary inlet 33, the chamber 402, the port 413 and the internal channel 401 in sequence, when the port 413 is opened, the flow path forms a passage, and when the port 413 is closed, the flow path is blocked, namely, the flow path between the secondary inlet and the secondary outlet of the secondary valve body is switched between a connection state and a blocking state by rotating the knob.

As shown in the figure, the valve core assembly includes a static plate 42 and a movable plate 43 contacting the static plate 42 and being rotatable relative to the static plate 42, the movable plate 43 is connected with one end of the valve core rod 44, the movable plate 43 is driven by the valve core rod 44 to rotate by operating the valve core rod 44, the other end of the valve core rod 44 extends out of the valve core seat 41, and the valve core rod 44 forms a sealing fit with the valve core seat 41 through a sealing ring 440. The side face of the movable grinding sheet 43 is opposite to the through hole, the movable grinding sheet 43 and the through hole are in the same height position, and the movable grinding sheet 43 is rotated to switch the positions of opening and closing the through hole. The side of the dynamic grinding sheet is provided with a first part and a second part. A first portion of the side surface of the movable land 43 is brought into sealing contact with the valve cartridge seat 41, and a second portion of the side surface of the movable land 43 is not brought into contact with the valve cartridge seat 41.
