In other words, the inflator 2 inflates the air dissolving device 1 once, and it can be ensured that the air leakage amount in the air dissolving device 1 does not affect the generation quality of bubble water within the preset time threshold.

That is to say, in the process of outputting a gas-liquid mixture by intermittently using a water heater, after each interruption, whether the continuous water stopping time is greater than or equal to a preset time threshold value or not is judged, if so, it is indicated that the air pressure in the air dissolving device 1 is insufficient due to reasons such as tightness and the like, so that the quality of bubble water generated by the micro-bubble generating device 4 next time is influenced, and further, when the bubble water is generated next time, the air inflating device 2 is started first, so that the air inflating device 2 compresses air and injects the air into the air dissolving device 1, then, a water inlet of the air dissolving device 1 is opened by controlling the water stop valve 7, and a water supply pipe injects water into the air dissolving device 1, so that the bubble content of the bubble water can meet the design requirements, and the cleaning effect of the bubble water can be ensured; if not, the air quantity and the air pressure in the air dissolving device 1 are enough to continuously generate bubble water, and further, when the bubble water is generated next time, the air does not need to be charged again, the water inlet of the air dissolving device 1 can be directly opened through controlling the water stop valve 7, so that the water and the air are mixed in the air dissolving device 1 and then flow out through the micro-bubble generating device 4, and the bubble water is output.

It should be noted that, after the inflator 2 is controlled to charge air into the air dissolving device 1, the calculation of the continuous water cut-off time is restarted.

Preferably, in the process of outputting the gas-liquid mixture by using the water heater discontinuously, when any one of the conditions that the accumulated water amount is greater than or equal to the second preset water amount and the continuous water stopping time is greater than or equal to the preset time threshold is met, a certain amount of air is refilled into the dissolved air tank when next bubble water is generated, so that the bubble content of the bubble water is ensured to meet the design requirement, and the effect of cleaning articles by the bubble water is ensured.

in step S301, the user triggers a bubble water function key.

If the key is pressed once, step S314 is executed, if the key is pressed twice, step S302 is executed, and if the key is pressed three times, step S319 is executed.

Step S302, the normal temperature bubble water function is started.

Step S303, the user taps the water to boil the water.

In step S304, water flows through the water flow sensor.

And step S305, after receiving the water flow signal for 0.5S, starting the inflator pump.

And step S306, closing the water stop valve.

In step S307, the check valve is opened.

After step S308, 5S, the water shutoff valve is opened, and then step S309 and step S311 are performed.

Step S309, after 0.5S, the inflator is turned off.

The controller controls the water stop valve to be opened when the inflator pump is controlled to be opened, so that a certain amount of air is filled into the dissolved air tank, after the air is continuously supplied for 5 seconds, the controller controls the water stop valve to be opened first to open the water inlet of the dissolved air tank, then the inflator pump is closed, the time for closing the inflator pump is later than the time for closing the water stop valve, and water can be prevented from being poured into the air outlet of the inflator pump backwards when the water pressure is too high.

In step S310, the check valve is closed.

In step S311, the gas and liquid are mixed in the dissolved gas tank.

And step S312, flowing out of the faucet bubbler.

The faucet is provided with a bubble water gear, when the bubble water gear is adjusted, mixed water and air are generated into bubble water through the faucet bubbler, and the bubble water is provided with a large number of micro-nano bubbles with the diameter of 0.1-50 microns.
