Fig. 1 is a flowchart of a control method of a micro bubble water generating system according to one embodiment of the present invention. The control method of the micro-bubble water generation system comprises the following steps:

in step S1, a user setting instruction is received.

In some embodiments of the present invention, the user instruction may be set by a user through an instruction button on the micro-bubble water generating system, and the user may set whether the micro-bubble water generating system generates bubble water through the user instruction.

In other embodiments of the present invention, the user setting instruction may be issued by the user through the smart home system, for example, whether bubble water is generated is controlled through a mobile phone APP (Application program), so as to facilitate improvement of user experience.

And step S2, when determining that the micro-bubble water generating system generates bubble water according to the user setting instruction, if a water flow signal is detected, controlling a water inlet of the air dissolving device to be closed, and controlling the air charging device to charge air into the air dissolving device.

Specifically, when determining that the micro-bubble water generating system gives out bubble water according to a user setting instruction, if a user opens a water tap, the water flow sensor can detect a water flow signal, the controller closes by controlling the water stop valve to close the water inlet of the air dissolving device so as to stop water inflow of the water supply pipe, and simultaneously opens the air charging device so as to compress air and inject the air into the air dissolving device so as to increase the pressure in the air dissolving device and the air quantity.

It should be noted that, after the water stop valve is closed, the water flow sensor will send out a signal that the water flow is zero, that is, the water flow signal is interrupted.

And step S3, after the air dissolving device is filled with air, controlling the water inlet of the air dissolving device to be opened, and controlling the air dissolving device to stop working, so that the air dissolving device mixes the inlet water and the air and inputs the mixture into the micro-bubble generating device, acquiring the accumulated water amount in the process of outputting bubble water, and when the accumulated water amount is larger than a first preset water amount, controlling the water inlet of the air dissolving device to be closed again, and controlling the air dissolving device to fill air into the air dissolving device.

Specifically, after the air dissolving device is filled with a certain amount of air, the air quantity and the air pressure in the air dissolving device meet the requirement of generating bubble water by the micro-bubble generating device, the water inlet of the air dissolving device is opened by controlling the opening of the water stop valve, the air dissolving device is controlled to stop working, after the water inlet is opened, a water flow signal can be detected by the water supply pipe under the condition of water, the air and the water are mixed in the air dissolving device, and the mixed gas and liquid flow out through the micro-bubble generating device, so that the bubble water is generated, and further the instruction of a user is completed.

In the process of outputting bubble water, the accumulated water amount L1 is also obtained, and when the accumulated water amount is greater than the first preset water amount L1, the water inlet of the air dissolving device is controlled to be closed again, and the air inflating device is controlled to inflate air into the air dissolving device, in other words, the air inflating device inflates the air dissolving device once, so that the bubble generating device can continuously generate the bubble water with the first preset water amount L1 to meet the design requirement. When the bubble water is continuously generated, the accumulated water amount L1 is the water amount injected into the air dissolving device by the water supply pipe, and the water amount injected into the air dissolving device by the water supply pipe is the same as the water amount flowing through the water flow sensor, so that the accumulated water amount L1 can be obtained by reading a water flow signal through the controller, when the accumulated water amount L1 is larger than a first preset water amount L1, the air consumption in the air dissolving device is more, the air pressure is insufficient, the quality of the bubble water generated by the micro-bubble generating device is influenced, at the moment, the water stop valve is closed to re-close the water inlet of the air dissolving device, and the air charging device is re-opened to compress the air and inject the air into the air dissolving device to increase the pressure and the air amount in the air dissolving device, thereby being beneficial to ensuring that the bubble content of the generated bubble water meets the design requirements and further being beneficial to ensuring the cleaning effect of the bubble water. Optionally, the first preset amount of water K1 is 1 liter or 2 liters.

In some embodiments of the present invention, during the process of outputting bubble water, if the interruption of the water flow signal is detected, acquiring an accumulated water amount L1, and determining whether the accumulated water amount L1 is greater than or equal to a second preset water amount L2, wherein if yes, when the water flow signal is detected again, controlling a water inlet of the air dissolving device to be closed, and controlling the air charging device to charge air into the air dissolving device; if not, opening a water inlet of the air dissolving device to output bubble water when the water flow signal is detected again. In other words, the inflator inflates the air dissolving device once, so that the bubble generating device can generate the bubble water satisfying the design requirement by alternately generating the second preset water amount L2 by the bubble water.

That is to say, in the process of generating bubble water by using the micro-bubble water generating system discontinuously, the cumulative water amount L1 is the sum of the water amounts injected into the air dissolving device by the water supply pipe each time, so as to obtain the total water amount, after each interruption, whether the used cumulative water amount L1 is greater than or equal to a second preset water amount L2 is judged, if so, the air consumption in the air dissolving device is high, the air pressure is insufficient, the quality of bubble water generated by the micro-bubble generating device next time is influenced, further, when bubble water is generated next time, the air charging device is started first, so that the air charging device compresses air and injects the air into the air dissolving device, then, the water inlet of the air dissolving device is opened by controlling the water stop valve, the water supply pipe injects water into the air dissolving device, so as to ensure that the bubble content of the bubble water meets the design requirement, and further, the cleaning effect of the bubble water is ensured; if not, the air quantity and the air pressure in the air dissolving device 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 can be directly opened by controlling the water stop valve, so that the water and the air are mixed in the air dissolving device and flow out through the micro-bubble generating device, and the bubble water is output.

It should be noted that, after the inflator is controlled to charge air into the air dissolving device, the calculation of the cumulative water amount l1 is restarted.

Preferably, the second preset water amount L2 is smaller than the first preset water amount L1, so as to prevent the air pressure inside the air dissolving device from being insufficient due to tightness and the like, and the quality of the bubble water is not affected during the intermittent generation of the bubble water.

In some embodiments of the invention, in the process of outputting bubble water, if the interruption of the water flow signal is detected, the continuous water cut-off time T4 is obtained, and whether the continuous water cut-off time T4 is greater than or equal to a preset time threshold T4 is judged, wherein if yes, when the water flow signal is detected again, the water inlet of the air dissolving device is controlled to be closed, and the air charging device is controlled to charge air into the air dissolving device, so that the bubble content of the bubble water can meet the design requirement, and the cleaning effect of the bubble water can be ensured; if not, opening a water inlet of the air dissolving device to output bubble water when the water flow signal is detected again. In other words, the air dissolving device is inflated by the inflating device once, and the air leakage quantity in the air dissolving device can be ensured not to influence the generation quality of bubble water within the preset time threshold T4.

That is to say, in the process of generating bubble water by discontinuously using the micro bubble water generating system, after each interruption, whether the continuous water stopping time T4 is greater than or equal to the preset time threshold T4 is judged, if yes, it is indicated that the air pressure in the air dissolving device is insufficient due to the sealing property and other reasons, the quality of the bubble water generated by the micro bubble generating device next time is influenced, and then when the bubble water is generated next time, the air charging device is started first, so that the air charging device compresses air and injects the compressed air into the air dissolving device, then the water inlet of the air dissolving device is opened by controlling the water stop valve, and the water supply pipe injects water into the air dissolving device, so that the bubble content of the bubble water meets the design requirement, and further the cleaning effect of the bubble water is ensured; if not, the air quantity and the air pressure in the air dissolving device 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 can be directly opened by controlling the water stop valve, so that the water and the air are mixed in the air dissolving device and flow out through the micro-bubble generating device, and the bubble water is output.

It should be noted that, after the inflator is controlled to charge air into the air dissolving device, the calculation of the continuous water cut-off time t4 is restarted.

Preferably, when any one of the conditions that the accumulated water amount L2 is more than or equal to L2 and the continuous water stopping time T4 is more than or equal to T4 is met in the process of generating bubble water by using the micro-bubble water generation system discontinuously, a certain amount of air is charged into the dissolved air tank again when the 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.

Specifically, after the inflator starts to work for a first preset time T2, the inflator charges a certain amount of air into the air dissolving device, so that the air volume and the air pressure in the air dissolving device meet the requirement of the micro-bubble generating device for generating bubble water, the water inlet of the air dissolving device is opened by controlling the opening of the water stop valve, so that water is injected into the air dissolving device when the pressure and the air volume in the air dissolving device meet the design requirement, at this time, the water path in the heating device starts to flow, the water flow sensor detects a water flow signal, the controller controls the working state of the thermal device, if the user needs the constant-temperature bubble water, the heating device does not work, the constant-temperature water flows through the non-working heating device through the water supply pipe and then is injected into the air dissolving device, and if the user needs the constant-temperature bubble water, the heating device works, and the heating device injects hot water into the air dissolving device.

And controlling the inflation device to stop working after the inflation device starts to work for a second preset time T3 to prevent the pressure in the air dissolving device from being too large, so that the air and the water reaching the preset temperature are mixed in the air dissolving device, and the mixed gas and liquid flow out through the micro-bubble generating device, so that the bubble water at the preset temperature is generated, and further the instruction of the user is completed.

Further, in the process of outputting the bubble water with the preset temperature, the accumulated water amount L1 is also obtained, and when the accumulated water amount is greater than the first preset water amount L1, the water inlet of the air dissolving device is controlled to be closed again, and the air inflating device is controlled to inflate air into the air dissolving device, in other words, the air inflating device inflates the air dissolving device once, so that the bubble generating device can continuously generate the bubble water with the first preset water amount L1 into the bubble water meeting the design requirement.

When the bubble water is continuously generated, the accumulated water amount L1 is the water amount injected into the air dissolving device by the heating device, and the water amount injected into the air dissolving device by the heating device is the same as the water amount flowing through the water flow sensor, so that the accumulated water amount L1 can be obtained by reading a water flow signal through the controller, when the accumulated water amount L1 is greater than a first preset water amount L1, the air consumption in the air dissolving device is more, the air pressure is insufficient, the quality of the bubble water generated by the micro-bubble generating device is influenced, at the moment, the water inlet of the air dissolving device is closed again by closing the water stop valve, the air charging device is restarted, the air charging device compresses air and injects the air dissolving device to increase the pressure and the air amount in the air dissolving device, thereby being beneficial to ensuring that the bubble content of the generated bubble water meets the design requirements and further being beneficial to ensuring the cleaning effect of the bubble water.

Optionally, the first preset amount of water K1 is 1 liter or 2 liters.

In some embodiments of the present invention, during the operation of the heating device to generate hot water, the temperature K3 of the hot water is also detected, and when the temperature of the hot water is greater than the preset temperature K3, the heating device is controlled to stop operating, so that the unheated water flow enters the micro-bubble generating device after being directly mixed with air in the air dissolving device, so as to output normal-temperature bubble water.

That is to say, in the process of intermittently using the water heater to generate bubble water at a preset temperature, after each interruption, whether the continuous water-stopping time T4 is greater than or equal to the preset time threshold T4 is judged, if yes, it is indicated that the air pressure in the air dissolving device is insufficient due to reasons such as sealing performance and the like, the quality of the bubble water generated by the water heater next time is affected, and then when the bubble water is generated next time, the air charging device is started first to compress air and inject the air into the air dissolving device, and then the heating device is controlled to inject water at the preset temperature into the air dissolving device, so that the bubble content of the bubble water meets the design requirements, and further the cleaning effect of the bubble water is ensured; if not, the air quantity and the air pressure in the air dissolving device are enough to continuously generate bubble water, and then when the bubble water is generated next time, whether the heating device is controlled to work or not can be directly judged according to a user instruction, if the user needs the normal-temperature bubble water, the heating device does not work, the normal-temperature water flows through the heating device which does not work through a water supply pipe and then is injected into the air dissolving device, and if the user needs the hot-bubble water, the heating device works, and the heating device heats the water to the preset temperature and then injects the water into the air dissolving device. It should be noted that, after the inflator is controlled to charge air into the air dissolving device, the calculation of the continuous water cut-off time t4 is restarted.

Preferably, when any one of the conditions that the accumulated water amount L2 is more than or equal to L2 and the continuous water stopping time T4 is more than or equal to T4 is met in the process of generating bubble water by using the water heater discontinuously, a certain amount of air is filled into the dissolved air tank again when the bubble water is generated next time, 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 favorably ensured.
