DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the technical solutions of the present disclosure clearer, the present disclosure will be further described in conjunction with the embodiments and the accompanying drawings.

[0030] Referring to FIGS. 1-8, an electronic water outlet terminal is preferably a pull-out faucet in this embodiment. The electronic water outlet terminal comprises an electronic valve 1, a mechanical valve 2, a control module 3 for controlling the electronic valve 1, and an operation handle 4 for controlling the mechanical valve 2. The mechanical valve 2 comprises a cold water inlet 211, a hot water inlet 212, and a water outlet 213. The electronic valve 1 and the mechanical valve 2 are connected in series.

[0031] When the operation handle 4 is in a closed position, the water outlet 213 is kept in fluid connection with the cold water inlet 211. Therefore, when a user issues a water discharge command to the control module 3, the control module 3 sends a control signal to control the electronic valve 1 to open. At this time, cold water flows from the electronic water outlet terminal. Therefore, even if the user does not move the operation handle 4 to an open position, the cold water can be used as normal. Thus, the problem that the operation handle 4 must be moved to the open position before use does not occur.

[0032] In this embodiment, the water discharge command is a touch water discharge command, an induction water discharge command, or a wireless water discharge command. Only a touch module, an infrared module, or wireless module, respectively, needs to be disposed in the electronic water outlet terminal. The touch module, the infrared module, and the wireless module are conventional and are not within the scope of protection for the present disclosure. Therefore, in this embodiment, the structure of the touch module, the infrared module, and the wireless module is not further described.

[0033] The electronic valve 1 is an electromagnetic valve. Those skilled in the art can also use other electronic valves as desired, which is a simple replacement of the embodiment.

[0034] The control module 3 comprises a control box 31 and a circuit board (the circuit board is not shown in FIGS. 1-8) disposed in the control box. A signal output terminal of the circuit board is connected to the electromagnetic valve. In other words, a signal output terminal of the control module 3 is connected to the electromagnetic valve. This allows the circuit board (or the control module 3) to control the electromagnetic valve to open or close.

[0035] In this embodiment, the mechanical valve 2 comprises a fixed ceramic piece 21 and a movable ceramic piece 22. The movable ceramic piece 22 is operatively coupled to the operation handle 4.

[0036] The fixed ceramic piece 21 defines the cold water inlet 211, the hot water inlet 212, and the water outlet 213. The movable ceramic piece 22 defines a water hole 221. In this embodiment, the cold water inlet 211, the hot water inlet 212, and the water outlet 213 are circumferentially distributed. The water hole 221 is located inside a circumference of the movable ceramic piece 22, and a part of the water hole 221 extends outwardly to form a protruding portion 222.

[0037] When the operation handle 4 is in the closed position, the protruding portion 222 of the water hole 221 connects the cold water inlet 211 with the water outlet 213. Thus, when the operation handle 4 is in the closed position, cold water can still flow through the mechanical valve 2.

[0038] The operation handle 4 is configured to drive the movable ceramic piece 22 to rotate. During rotation of the movable ceramic piece 22, the water hole 221 connects the cold water inlet 211 with the water outlet 213 or the water hole 221 concurrently connects the cold water inlet 211 and the hot water inlet 212 with the water outlet 213. In the present embodiment, when the movable ceramic piece 22 is rotated from an initial position, a connection area between the water hole 221 and the hot water inlet 212 gradually increases, so that a water temperature of water at the water outlet 213 gradually increases.

[0039] In some embodiments, when the operation handle 4 is in the closed position, the water hole 221 is configured to always be connected to the cold water inlet 211 during rotation of the water hole.

[0040] In some embodiments, the operation handle 4 is configured to drive the movable ceramic piece 22 to slide relative to the fixed ceramic piece 21. When the operation handle 4 is in the closed position, the water hole 221 is configured to only be connected to the cool water inlet 211 during rotation of the water hole 221 when the water hole 221 is at a first position. When the operation handle 4 is in the open position, the operation handle 4 drives the water hole 221 to slide to a second position configured to be connected to the hot water inlet 212 and the cold water inlet 211 synchronously during the rotation of the water hole 221. At this time, the operation handle 4 is rotated to drive the movable ceramic piece 22 to rotate concurrently, and the water hole 221 is rotated to connect to the hot water inlet 212 and the cold water inlet 211 synchronously.

[0041] The structure of other parts of the pull-out faucet belongs to the prior art and are not described further in the present embodiment.

[0042] In the embodiment, the electronic water outlet terminal is a pull-out faucet. In other embodiments, the electronic water outlet terminal may be a non-pulling faucet or a shower head.

[0043] It will be apparent to those skilled in the art that various modifications and variation can be made in the present disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the present disclosure cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
