Water channel switching mechanism of water outlet device and faucet

Abstract

The present invention discloses a water path switching mechanism and a faucet of a water outlet device, wherein a driving member drives an automatic reset unit to close a first water outlet channel and open a second water outlet channel, and the water pressure in the water inlet channel overcomes the reset force of the automatic reset unit to limit the automatic reset unit to a position where the second water outlet channel is opened, thereby connecting the water inlet channel to the second water outlet channel. At this time, if the driving member is driven again, the switching member switches at least between a first position and a second position to connect the second water outlet channel to the first water path or the second water path. At this time, if the water inlet channel is cut off, the automatic reset unit loses the water pressure force and resets under the action of the reset force, thereby connecting the water inlet channel to the first water outlet channel again. This scheme cleverly utilizes the cooperation between the water pressure in the water inlet channel and the automatic reset unit to realize water outlet state switching. After the water inlet channel is cut off, the default water outlet state is automatically restored, and the structure is simple and easy to assemble.

[0039] The specific working process of this embodiment is as follows:

[0040] like Figures 4 to 6As shown, when the water outlet device is filled with water, in the initial state, the automatic reset unit 40 closes the second water outlet channel 13 and opens the first water outlet channel 12. At this time, the water inlet channel 11 is connected with the first water outlet channel 12, and the driving member 20 is driven to drive the switching core 41 to close the first water outlet channel 12 and open the second water outlet channel 13. The water pressure of the water inlet channel 11 overcomes the elastic reset force of the elastic member 42 to limit the switching core 41 to the position of opening the second water outlet channel 13, thereby connecting the water inlet channel 11 with the second water outlet channel 13.

The switching core 41 loses the water pressure force and resets under the action of the elastic reset force, thereby connecting the water inlet channel 11 with the first water outlet channel 12 again.

[0041] The present invention cleverly utilizes the water pressure of the water inlet channel 11 and the cooperation of the automatic reset unit 40 to realize the switching of the water outlet state, which can simplify the product parts, make the product structure simple, and facilitate assembly. After the first water outlet channel 12 is closed, during the process of water outlet from the second water outlet channel 13, the solution switches to the first water channel through the switching member 30, and also enables water outlet from the first water outlet channel 12. Moreover, after switching to any water channel for water outlet, the solution only needs to cut off the water inlet channel 11 to restore the water outlet device to the state of water outlet from the first water outlet channel 12, that is, each time the water outlet device is closed, the water outlet device will automatically restore to the default initial state, which is convenient for use.
