When the first electronic control valve 2 cannot be used, the mechanical switch valve 3 can be opened to ensure the normal use of the water outlet device.

Referring to fig. 1, during this operation, the flow direction of the fluid is indicated by the open arrows in fig. 1. When an external water source enters the temperature regulating valve 1 through the cold and hot water inlet pipe 20 to regulate temperature, the external water source passes through the first electronic control valve 2 and enters the water-air mixing tank 4, meanwhile, the air pump 6 supplies air to the water-air mixing tank 4, at the moment, air in the water-air mixing tank 4 is mixed with water in a pressure maintaining manner, dissolved oxygen in water is increased, and the dissolved oxygen is discharged from the water outlet of the water-air mixing tank 4 and the micro-bubble water outlet terminal 5.

At this time, the normal water also containing no microbubbles is discharged from the microbubble water discharge terminal 5.

In this possible design, a level sensor for detecting the level of the liquid is provided in the water-air mixing tank 4. Illustratively, referring to FIG. 1, the liquid level sensor includes a high liquid level probe 18 and a low liquid level probe 19, the high liquid level probe 18 being disposed near the top of the water-gas mixing tank 4 and the low liquid level probe 19 being disposed near the bottom of the water-gas mixing tank 4.

In this embodiment, the first setting position is a high liquid level, the second setting position is a low liquid level, the high liquid level probe 18 is located at the first setting position, and the low liquid level probe 19 is located at the second setting position.

The air pump 6 realizes intermittent operation by the circulation, saves electricity consumption, and prolongs the service time of the micro-bubble function under the condition of a certain electricity quantity.

It should be noted that the structure and the working principle of the high level probe 18 and the low level probe 19 are all the prior art, and will not be described in detail herein.

In another possible design, the air pump 6 is configured to turn on for a second set period of time every time the first set period of time is turned off.

The water outlet device is characterized by comprising a first electronic control valve, a mechanical switch valve, a water-gas mixing tank, a micro-bubble water outlet terminal and an air pump, wherein an inlet of the first electronic control valve and an inlet of the mechanical switch valve are both used for being communicated with an external water source, an outlet of the first electronic control valve is communicated with a water inlet of the water-gas mixing tank, and a water outlet of the water-gas mixing tank and an outlet of the mechanical switch valve are both communicated with the micro-bubble water outlet terminal; the air outlet of the air pump is communicated with the air inlet of the water-air mixing tank and is used for intermittently supplying air into the water-air mixing tank.

2. The water outlet device of claim 1, wherein the air pump is configured to be turned on when a liquid level within the water-air mixing tank is in a first set position, and is further configured to be turned off when a liquid level within the water-air mixing tank is in a second set position, wherein the first set position is above the second set position.

3. The water outlet device of claim 1, wherein the air pump is configured to turn on for a second set period of time for each turn off of the first set period of time.

4. The water outlet device according to claim 1, wherein a first check valve is provided between the first electronic control valve and the water-gas mixing tank, and a second check valve is provided between the air pump and the water-gas mixing tank.

5. The water outlet device of claim 1, further comprising a control circuit coupled to the air pump and the first electronic control valve.

6. The water outlet device according to any one of claims 1 to 5, further comprising a housing, wherein the first electronic control valve and the air pump are both installed inside the housing, and wherein the water-air mixing tank is installed at an outer surface of a side wall of the housing; the operating end of the mechanical switch valve is positioned outside the shell.

7. The water outlet device according to claim 6, wherein the housing is provided with a control panel, a conventional water outlet switch and a micro-bubble electronic switch are arranged on the control panel, the conventional water outlet switch is connected with the first electronic control valve, and the micro-bubble electronic switch is connected with the air pump.

8. The water outlet device of any one of claims 1 to 5, wherein the microbubble water outlet terminal comprises a hand-held shower head.

9. The water outlet device of claim 8, wherein the microbubble water outlet terminal further comprises a top shower head, and a second electronic control valve is disposed between the top shower head and the water outlet of the water-gas mixing tank.

10. The water outlet device according to any one of claims 1 to 5, further comprising a temperature regulating valve and a cold and hot water inlet pipe, wherein the inlet of the first electronically controlled valve and the inlet of the mechanical switching valve are both in communication with the cold and hot water inlet pipe through the temperature regulating valve.
