A water inlet connection device of a shower faucet of the present utility model, when specifically applied, two water inlet connection devices of the present utility model are used together with a shower faucet 8, specifically, the joint body of the two water inlet connection devices The water inlets 11 of 1 are respectively connected to the water supply pipelines concealed in the wall, so that the water outlet 12 of the joint body 1 of one of the water inlet connection devices is connected to the hot water inlet end of the shower faucet 8, and the other water inlet connection device The water outlet 12 of the joint body 1 is connected to the cold water inlet end of the shower faucet 8, as shown in FIG. 1 .

During normal water intake, the second water passage hole 54 of the holding cylinder 52, the first water passage hole 41 of the flow regulating cylinder 4, and the water inlet 11 of the joint body 1 correspond one by one. The gasket 3 blocks the first water outlet hole 13 of the joint body 1, as shown in Figure 4 and A in Figure 5 (the arrow in Figure 4 indicates the direction of water flow). At this time, the water inlet 11 of the joint body 1 has the largest water passing area, and correspondingly, the water inlet flow of the joint body 1 is the largest.

The water inlet connection device of a shower faucet of the utility model also has the function of reverse flushing, and the specific operation is: close the shower faucet connected to it, and rotate the knob part 53 to make the filter core 5 drive the flow regulating cylinder 4 to rotate Until the third water hole 42 corresponds to the inside and outside of the water inlet 11 of the joint body 1, at the same time, the second water outlet hole 44 of the flow regulating cylinder 4 is connected to the first water outlet hole 13 of the joint body 1, as shown in FIG. 6 . At this time, the water flows to the filter cartridge 51 through the third water hole 42 of the flow regulating cylinder 4 and the water passage 55 of the holding cylinder 52 in sequence, and flows into the filter cartridge 51 from the outside of the side of the filter cartridge 51. Attached impurities and foreign objects are washed away from the wall surface of the filter cartridge 51 , and the obtained waste water flows out through the second water outlet hole 44 of the flow regulating cylinder 4 and the first water outlet hole 13 of the joint body 1 in sequence.

A water inlet connection device for a shower faucet of the utility model can also disassemble the filter element 5 for cleaning. The water hole 41 and the second water hole 54 are all completely staggered with the water inlet 11 of the joint body 1, that is, the side of the flow regulating cylinder 4 is completely blocked the water inlet 11 of the joint body 1, and the joint body 1 stops water intake, as Figure 7 shows. Next, unscrew the fastener 7, and take out the friction ring 6 and the filter core 5, as shown in FIG. 8 . At this time, since the flow regulating cylinder 4 blocks the water inlet 11 of the joint body 1 , there is no need to close the water supply channel at the front end of the water inlet 11 of the joint body 1 .

The above embodiments are only used to further illustrate the water inlet connection device of a shower faucet of the present invention, but the present invention is not limited to the embodiments, and any simple modification made to the above embodiments based on the technical essence of the present invention , equivalent changes and modifications all fall within the protection scope of the technical solution of the utility model.
