[0002] In daily life, due to different water needs, users have different demands for water output, such as pure water and purified water, cold water and hot water, etc., so water output equipment (such as faucets) are usually equipped with multiple water channels.

[0003] At present, the switching valve core on the existing water outlet equipment is usually set on the water inlet end, and the water flows out through the same water outlet pipe when the water is discharged. Therefore, when different water channels are switched, the water flow of the previous water channel remaining in the water outlet pipe is mixed with the water flow of the next water channel and flows out together, which affects the water outlet effect, especially on the water outlet equipment with a bent structure of the water outlet pipe, resulting in an increase in water consumption.

[0004] At the same time, due to the installation position limitation of the switching valve core in the existing water outlet equipment, when a water outlet failure occurs, it is usually necessary to replace the entire water outlet equipment for maintenance, which is inconvenient to operate and the maintenance cost is relatively high.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

Through the assembled structure of the main base 1, the convenience of installing the switching component 2 in the main base 1 is improved, while the manufacturing difficulty of the first liquid inlet channel 11, the second liquid inlet channel 12, the first liquid outlet channel 13 and the second liquid outlet channel 14 on the main base 1 is reduced. In addition, since the first base body 3, the second base body 4 and the third base body 5 can be manufactured separately, the manufacturing loss is reduced and the manufacturing efficiency of the main base 1 is guaranteed.

[0037] Among them, a liquid guide plate 41 is inserted on the top of the second seat body 4, and the liquid guide plate 41 is sandwiched between the second seat body 4 and the switching assembly 2.
