[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Refer to Figures 1 to 5 , a switching device with automatic reset, comprising:

[0033] A main body 10 having a water inlet passage 11, a first water outlet passage 12 and a second water outlet passage 13;

[0034] A switching member 20 movably arranged relative to the main body 10. When the switching member 20 moves to the first position, the water inlet passage 11 is communicated with the first water outlet passage 12. When the switching member 20 moves to the second position, the water inlet passage 11 is communicated with the second water outlet passage 13;

[0035] A driving member 30 in transmission connection with the switching member 20;

[0036] A pressure chamber 40. When the driving member 30 drives the switching member 20 to move to the second position, a part of the water in the second water outlet passage 13 is diverted to the pressure chamber 40, and the driving member 30 drives the switching member 20 to reset to the first position under the water pressure in the pressure chamber 40.

[0037] In this embodiment, a piston 50 movably arranged in the pressure chamber 40 is further included. The driving member 30 is in transmission cooperation with the piston 50. The piston 50 is provided with a piston chamber 51 communicating the second water outlet passage 13 and the pressure chamber 40. The piston 50 drives the driving member 30 to move under the water pressure in the pressure chamber 40. By providing the piston 50 structure, the switching time of the water path can be prolonged, and the water path resets after a relatively long switching time, meeting the user's usage requirements.

[0038] In this embodiment, the piston 50 is provided with a seal 52 that is in sealed sliding fit with the pressure chamber 40. An inlet hole 53 communicating the piston chamber 51 with the second water outlet channel 13 is provided on the side wall of the piston 50 above the seal 52, and a water outlet hole 54 communicating the piston chamber 51 with the pressure chamber 40 is provided at the bottom of the piston 50.

[0039] In this embodiment, a first elastic member 55 that provides an elastic force to the piston 50 is further included, which plays an auxiliary role in resetting the piston 50.

[0040] In this embodiment, one end of the driving member 30 is movably limited in the piston chamber 51, and a water passing gap communicating the second water outlet channel 13 and the pressure chamber 40 is formed between the driving member 30 and the inner wall of the piston chamber 51. The water passing gap allows water to pass through slowly, and thus the driving member 30 forms a damped motion. When the driving member 30 moves, the driving member 30 is separated from the upper part of the piston chamber 51, and the piston 50 moves towards the bottom of the pressure chamber 40 under the action of water pressure. When the driving member 30 moves to the bottom of the piston chamber 51, it pushes the piston 50 to continue moving towards the bottom of the pressure chamber 40.

[0041] In this embodiment, a second elastic member 31 that provides an elastic force to the driving member 30 is further included, which plays an auxiliary role in resetting the driving member 30.

[0042] In this embodiment, a water distributor 60 is provided in the main body 10. The water distributor 60 is provided with a first valve port 61 communicating with the first water outlet channel 12 and a second valve port 62 communicating with the second water outlet channel 13. The switching member 20 is provided with a sealing portion 21. When the switching member 20 moves to the first position, the sealing portion 21 closes the second valve port 62. When the switching member 20 moves to the second position, the sealing portion 21 closes the first valve port 61.

[0043] In this embodiment, a swing rod 70 rotatably mounted on the main body 10 is further included. The driving member 30 drives the switching member 20 through the swing rod 70. Specifically, the driving member 30 is a driving rod, the switching member 20 is a switching rod, and the driving member 30 and the switching rod are connected on the same side of the fulcrum of the swing rod 70. When the driving member 30 moves downward, the swing rod 70 drives the switching member 20 to move downward. When the driving member 30 moves upward, the swing rod 70 drives the switching member 20 to move upward.

[0044] This solution drives the switching member 20 to automatically reset through the cooperation of the pressure chamber 40 and the driving member 30. It only needs one operation to realize the switching and reset of the water path. The water path automatically returns to the default mode, which not only meets the use requirements but also is convenient for users to operate. Moreover, the structure is simple and suitable for popularization.

[0045] In addition, the present invention also provides a faucet, which includes a switching device with automatic reset as described above. The faucet includes a housing 80, and the main body 10 is installed in the housing 80. A lower water outlet 81 communicating with the first water outlet channel 12 is provided at the bottom of the housing 80, and an upper water outlet 82 communicating with the second water outlet channel 13 is provided above the housing 80.

[0046] In this embodiment, it further includes an adapter 90 installed at one end of the main body 10. The adapter 90 has a diversion channel communicating the second water outlet channel 13 and the second water outlet. Specifically, the adapter 90 is fixedly installed on one side of the main body 10 through a nut.

[0047] The specific working process of this embodiment is as follows:

[0048] As Figure 4 and Figure 5 shown, in the default state, the switching member 20 is located at the first position, and the water inlet channel 11 is communicated with the first water outlet channel 12. The water flow in the water inlet channel 11 flows out from the first water outlet channel 12. Press the driving member 30, and the swing rod 70 swings downward to drive the switching member 20 to move downward to the second position. At this time, the water inlet channel 11 is communicated with the second water outlet channel 13. At the same time, the driving member 30 is separated from the upper part of the piston chamber 51, and the piston 50 moves towards the bottom of the pressure chamber 40 under the action of water pressure. When the driving member 30 moves to the bottom of the piston chamber 51, it pushes the piston 50 to continue moving towards the bottom of the pressure chamber 40. During the process of the water inlet channel 11 feeding water into the second water outlet channel 13, part of the water is diverted from the piston chamber 51 to the pressure chamber 40. When the water pressure in the pressure chamber 40 is balanced with the water pressure in the second water outlet channel 13, the piston 50 is reset under the auxiliary action of the first elastic member 55, and at the same time, the driving member 30 is reset under the auxiliary action of the second elastic member 31, and then the water outlet device automatically returns to the state where the water inlet channel 11 is communicated with the first water outlet channel 12.

[0049] Alternatively, the piston 50 can also be reset only under the action of the water pressure in the pressure chamber 40 by setting the contact area between the inner side of the piston chamber 51 and the water in the pressure chamber 40 to be larger than the contact area between the outer side of the piston 50 and the water in the second water outlet channel 13, and the piston 50 is reset through the pressure difference.

[0050] The upper water outlet 82 in this solution is convenient for users to rinse their mouths. The switching device with automatic reset automatically returns to the lower water outlet function to prevent water from splashing onto the user when it is turned on next time.

[0051] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the forms disclosed herein, should not be construed as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the above teachings or the skills or knowledge in the relevant field.
