The first water channel assembly 1 includes a water inlet 1a and a water outlet, the water outlet includes at least a first water outlet 11b and a second water outlet 12b, and the first switching plug 31 is provided between the water inlet 1a and the first water outlet 11b; the second water channel assembly 2 includes a water inlet channel and a water diversion channel, the water inlet channel includes at least a first water inlet channel 21a and a second water inlet channel 21b, the first water inlet channel 21a and the second water inlet channel 21b are respectively connected to the first water flow pipe 11 and the second water flow pipe 12 (or Said second water inlet channel 21b is provided with the second switching plug 32; said water diversion channel at least comprises a first water diversion channel 41, a second water diversion channel 42 and a third water diversion channel 43, wherein said first water diversion channel 41 is connected with said first water inlet channel 21a, said second water diversion channel 42 and said third water diversion channel 43 are both connected with said second water inlet channel 21b, and said second switching plug 32 is provided at the connection between said second water diversion channel 42 and said third water diversion channel 43.

[0024] Preferably, see Attachment Figures 4A to 4B, the second water passage 12 is a normal water outlet channel, and the first water inlet channel 21a is a normal water outlet channel. In this way, since the first water passage 11 is connected to the first water inlet channel 21a, and the second water passage 12 is connected to the second water inlet channel 21b, at this time, when water flows in from the water inlet 1a of the first water channel assembly 11, the first switching plug 31 and the second switching plug 32 cut off the water paths of the first water branch channel 41 and the third water branch channel 43, and the water flows into the second water passage 12 and the second water inlet channel 21b in turn, and flows out from the second water branch channel 42. At this time, the water channel assembly is in the first water outlet state A; when the second switching plug 32 is pressed, the connection between the second water branch channel 42 and the second water inlet channel 21b is closed, and at the same time the third water branch channel 43 is closed. The water channel 43 is connected to the second water inlet channel 21b, and the water channel component is in the second water outlet state B at this time; when the first switching valve 31 is pressed to open, the water flows into the second water flow pipe 12 and also flows into the first water flow pipe 11 and the first water inlet channel 21a in sequence, so that the water flow can also flow out from the first water branch channel 41 connected to the first water inlet channel 21a to form a C-shaped water splash, thereby forming a combined third water outlet state A+C or a fourth water outlet state B+C with the first water outlet state A and the second water outlet state B. In this way, the water channel component can be applied to different usage scenarios in actual use, and the water splash can be changed and combined, making it more multifunctional, convenient and easy for users to use.

A plug body 311 is provided at the bottom of the valve stem 31b. A sealing ring a is sleeved on the outer periphery of the plug body 311. The plug body 311 is used to block the water connection when the valve stem 31b descends, for example, to block the connection between the first water outlet 11b and the first water inlet channel 21a. A clamping piece 312 is provided at the place where the valve stem 31b extends out of the first water pipe 11. The clamping piece 312 can be connected to a button to control the opening or closing of the switching bolt. Specifically, refer to the attached Figure 2The first water passage 11 includes a transverse water channel 111 and a longitudinal mounting seat 112 which are interconnected. The transverse water channel 111 is connected to the first water outlet 11b. The first switching bolt 31 is placed in the longitudinal mounting seat 112. A limiting plate 113 is arranged on the periphery of the longitudinal mounting seat 112. A limiting groove 114 is formed between the top of the longitudinal mounting seat 112 and the limiting plate 113. At least two sealing gaskets b are sleeved on the periphery of the body 31a, and a protrusion 31d matching the limiting groove 114 is extended from the periphery of the body 31a, so that the valve stem can be reliably limited to a certain position to prevent dislocation. Furthermore, the plug body 311 has a groove 311a with an opening at the bottom and a closed upper end. The outer periphery of the plug body 311 is provided with a depression near the upper end of the groove 311a, and the sealing ring a is arranged in the depression, wherein the bottom of the body 31a is provided with an inclined surface d near the valve stem 31b, and the inclined surface d can fit well with the sealing ring a to ensure sealing; the waterway component is provided with a spring seat 31e relative to the position of the groove 311a, and one end of the spring 31c is connected to the spring seat 31e, and the other end is matched in the groove 311a, so that the spring can be limited to a certain axial position. In addition, the second switching bolt 32 can be arranged in a similar manner to the first switching bolt 31, and the water inlet description is not repeated here.

[0026] The following will be combined with the attached Figure 5 and attached Figures 6A to 6D The application of the water channel assembly in the pull-out head device is specifically described in the following. Figure 5 The pull-out head device includes a housing 5, a water channel assembly and a water outlet, the water channel assembly and the water outlet are both arranged in the housing 5, the water outlet includes a first water outlet 61, a second water outlet 62 and a third water outlet 63, the first water outlet 61 is sleeved at a certain interval on the periphery of the third water outlet 63 to form a water outlet waterway, that is, the first water outlet 61 is connected to the first water channel 41 to form the C-shaped water splash described above, which can be a waterfall water splash outlet, that is, the water outlet waterway is a waterfall waterway (refer to the attached Figure 6C and 6D The third water outlet 63 is connected to the second water channel assembly 2 and a through hole 63a is provided in the middle of the third water outlet 63. The second water outlet 62 is provided in the through hole 63a. The second water outlet 62 and the third water outlet 63 are provided with a second water outlet 62b and a third water outlet 63b respectively. The second water outlet 62b can be a bubble water outlet (i.e., the water outlet state A can be a bubble water outlet, see Fig. 6A ), the third water outlet 63b can be an angle water outlet (that is, the water outlet state B can be an angle water outlet, see Figure 6B). Referring to FIG. 6 , the third water outlet 63 includes a main body 631 and a trumpet 632. The main body 631 is connected to the second water channel assembly 2. The outer periphery of the trumpet 632 includes an inclined surface 63c and the bottom surface of the trumpet 632 is provided with the third water outlet hole 63b described above. The first water outlet 61 is provided with a slope 61a in the same inclination direction as the inclined surface 63c near the bottom. The slope 61a is arranged opposite to the inclined surface 63c. This arrangement can effectively utilize the space and facilitate the outflow of water in the water outlet, thereby ensuring the working reliability of the channel. Preferably, a rectifying device 71 is provided between the second water channel assembly 2 and the water outlet, and a flow limiter 72 is provided at the water inlet 1a of the first water channel assembly 1, so that the entire waterway is more stable and reliable. The pull-out head device of this design can not only have a strong impact force when using the pull-out head to clean dirt, but also because a layer of waterfall water splashes is added to the outer circle of the angle water outlet, the intensity of the water impact force can be guaranteed, thereby effectively preventing the inconvenience caused by splashing water. It is very convenient and has the characteristics of low cost and energy saving and environmental protection.
