Similarly, the second electromagnetic valve 90 can control the opening and closing of the second water outlet 131, and during the use process, the second water outlet 131 can be opened or closed according to the user requirement, so as to open or block the second water path formed by the water inlet pipe 10 and the second water outlet pipe 30.

Of course, in practical application, the second solenoid valve 90 may be installed at the side of the second connection structure, and may also be installed at the bottom or top of the water inlet pipe connection joint 13.

Referring to fig. 6, in an embodiment of the anti-siphon water feeding control device 100 according to the present invention, a pressure relief hole is formed in the connection joint 12, the pressure relief hole is communicated with the first water outlet 121 and the first water inlet 222, a fixed port communicated with the pressure relief hole is formed in a side wall of the connection joint 12, and the first electromagnetic valve 80 is mounted at the fixed port.

It can be understood that, by forming the fixing opening in the side wall of the connection joint 12 and installing the first solenoid valve 80 at the fixing opening, the arrangement not only ensures the compactness of the overall structure, but also facilitates the assembly of the first solenoid valve 80.

Specifically, the first solenoid valve 80 includes a sealing gasket 81, a fixing block 82, a valve body 83, and a buffer 84, and during an assembly process, the sealing gasket 81 and the buffer 84 are respectively mounted on two end surfaces of the fixing block 82 facing away from each other, then the fixing block 82 is covered on the fixing port, so that the sealing gasket 81 seals a gap between the fixing block 82 and the fixing port, and then the valve body 83 is mounted on an end surface of the fixing block 82 facing away from the fixing port, and is fixedly connected together by screws, so as to complete the assembly of the first solenoid valve 80.

When flushing, the valve body 83 is electrified to generate electromagnetic force, and the movable iron core in the valve body 83 together with the sealing plug is pulled to move away from the pressure relief hole, so that the pressure relief hole is conducted, that is, the first water outlet 121 is opened to conduct the first water path, and flushing is completed; after the water flushing is finished, the valve body 83 is powered off, the movable iron core of the valve body 83 is connected with the sealing plug and moves towards the pressure relief hole, so that the pressure relief hole is propped against by the sealing plug, the first water outlet 121 is closed, and the first water channel is blocked.

Further, the specific structure and the operation principle of the second electromagnetic valve 90 are the same as those of the first electromagnetic valve 80, and are not described in detail herein.

The utility model also provides an intelligent toilet which comprises the anti-siphon water feeding control device 100, and the specific structure of the intelligent toilet is detailed in the embodiment. Since the anti-siphon water feeding control device 100 adopts all technical solutions of the aforementioned embodiments, at least all the beneficial effects brought by all the technical solutions of the aforementioned embodiments are achieved, and no further description is given here.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
