[0034] Reference Figures 1 to 5 , a water channel switching structure of a water outlet device, comprising:

[0035] A water channel switching structure of a water outlet device, comprising:

[0036] The main body 10 has a water inlet channel 11, a first water outlet channel 12 and a second water outlet channel 13;

[0037] The pressure chamber 20 is connected to the water inlet channel 11;

[0038] The drain channel 30 is connected to the water inlet channel 11;

[0039] a switching member 40 movably disposed in the pressure chamber 20 , wherein when the switching member 40 moves to a first position, the switching member 40 opens the first water outlet channel 12 and closes the second water outlet channel 13 ; and when the switching member 40 moves to a second position, the switching member 40 closes the first water outlet channel 12 and opens the second water outlet channel 13 ;

[0040] The control member 50 is used to control the opening and closing of the drain channel 30 . When the drain channel 30 is closed, the switching member 40 can move to the second position under the action of the water pressure in the pressure chamber 20 .

[0041] In this embodiment, the switching member 40 includes a first sealing portion 41 that cooperates with the opening and closing of the first water outlet channel 12, and also includes a second sealing portion 42 that seals and cooperates with the second water outlet channel 13. Specifically, the switching member 40 includes a switching rod 43, and the first sealing portion 41 and the second sealing portion 42 are arranged at intervals along the axial direction of the switching rod 43.

[0042] In this embodiment, the water pressure bearing area S1 of the first sealing part 41 is greater than the water pressure bearing area S2 of the second sealing part 42, and thus the water pressure F1 of the second sealing part 42 is greater than the water pressure F2 on the first sealing part 41, so that the switching part 40 can move toward the second sealing part 42 under the action of water pressure. The working principle is simple and the function is stable.

[0043] In this embodiment, a first elastic member 60 is further included to provide elastic force to the switching member 40. When the drain channel 30 is closed, the water pressure in the pressure chamber 20 can overcome the elastic force of the first elastic member 60 to drive the switching member 40 to move to the second position. When the water inlet channel 11 stops water, the switching member 40 can move to the first position under the elastic force of the first elastic member 60. Only one operation is required to achieve switching and resetting of the water channel, and the water channel automatically returns to the default mode.

[0044] In this embodiment, the drainage channel 30 and the first water outlet channel 12 are respectively connected to the pressure chamber 20. When the drainage channel 30 is opened, the water in the water inlet channel 11 flows through the drainage channel 30 to the pressure chamber 20 and then flows out from the first water outlet channel 12. The water flow is concentrated and flows out from the first water outlet channel 12 to prevent water resource waste.

[0045] In this embodiment, a water diversion sleeve 70 is provided in the main body 10, the pressure chamber 20 is formed on the water diversion sleeve 70, and the water diversion sleeve 70 is provided with a drain port 71 connecting the pressure chamber 20 and the drain channel 30, and the control member 50 cooperates with the drain port 71 to open and close.

[0046] In this embodiment, a first valve port 14 is provided downstream of the drain port 71, and the drain port 71 is connected to the first water outlet channel 12 via the first valve port 14. The switching component 40 cooperates with the first valve port 14 for opening and closing. The water distribution sleeve 70 also includes a second valve port 72 connecting the water inlet channel 11 and the second water outlet channel 13. The first sealing portion 41 cooperates with the first valve port 14 for opening and closing, and the second sealing portion 42 cooperates with the second valve port 72 for opening and closing.

[0047] In this embodiment, the main body 10 is provided with a first accommodating chamber 15 in the radial direction and a second accommodating chamber 16 in the axial direction, and the first accommodating chamber 15 and the second accommodating chamber 16 are communicated with each other. The piston sleeve is arranged in the first accommodating chamber 15, and the control member 50 is movably arranged in the second accommodating chamber 16 along the axial direction of the main body 10 and corresponds to the position of the drain port 71. Specifically, the control member 50 includes a control rod 51 and a button 52 that cooperates with the control rod.

[0048] In this embodiment, a second elastic member 80 is further included to provide elastic force to the control member 50. Under the elastic force of the second elastic member 80, the control member 50 can move in the direction of opening the drainage channel 30, and the control member 50 can automatically reset to the initial state.

[0049] In addition, the present invention also proposes a faucet, including the water path switching structure of the above-mentioned water outlet device, the faucet includes a shell 90, the main body 10 is installed in the shell 90, and the bottom of the shell 90 is provided with a lower water outlet 91 connected to the first water outlet channel 12, and the top of the shell 90 is provided with an upper water outlet 92 connected to the second water outlet channel 13.

[0050] The specific working process of this embodiment is as follows:

[0051] like Figure 3 As shown, in the default state, the drain channel 30 is open, the switching member 40 is in the first position, the switching member 40 closes the second valve port 72 and opens the first valve port 14, the water inlet channel 11 is connected to the first water outlet channel 12, and the water in the water inlet channel 11 flows through the drain channel 30 and the pressure chamber 20 and then flows out of the first water outlet channel 12;

[0052] like Figure 4 As shown, the control member 50 is pressed, the control member 50 closes the drain port 71 and thus cuts off the drain channel 30. The switching member 40 moves to the second position across the drain port 71 under the action of the water pressure in the pressure chamber 20. The switching member 40 closes the first valve port 14 and opens the second valve port 72. The water inlet channel 11 is connected to the second water outlet channel 13, and the water in the water inlet channel 11 flows out of the second water outlet channel 13.

[0053] like Figure 5 As shown, the control member 50 is released, and the control member 50 is reset under the action of the second elastic member 80, and the drain port 71 is opened. However, at this time, the switching member 40 is still maintained in the second position under the action of water pressure. When the water inlet channel 11 stops inletting water, the switching member 40 loses the force of the water pressure and is reset to the initial state under the action of the first elastic member 60.

[0054] The upper water outlet 92 of this solution can be used by users to rinse their mouths. The automatic resetting switching device automatically restores to the lower water outlet function to prevent water from splashing to the user when it is turned on next time.
