Referring to FIG. 8, in some embodiments, the controller 60 is further configured to control the air intake control valve 29 to close for a fourth predetermined period of time before opening the air intake control valve 29, and to reacquire the flow rate of the bubble water after the air intake control valve 29 is restarted for a fifth predetermined period of time, where the fourth predetermined period of time is greater than the third predetermined period of time and less than the second predetermined period of time, and the fifth predetermined period of time is less than the third predetermined period of time, in the case where the flow rate of the bubble water is greater than the second predetermined flow rate and less than or equal to the third predetermined flow rate.

Referring to FIG. 8, in some embodiments, the controller 60 is further configured to maintain the intake control valve 29 open when the flow rate of the bubble water is greater than a third predetermined flow rate.

In this way, the controller 60 can control the air intake control valve 29 by detecting the usage time of the bubble water used by the user and the flow rate of the bubble water, and can adopt different control operations according to different situations of the bubble water taken by the user, thereby improving the usage experience of the water purifier 100.

Specifically, the air intake control valve 29 may be provided between the air intake 241 and the bubble water outlet 220 of the bubble water module 20, the air intake control valve 29 may be an air intake electromagnetic control valve, the air intake control valve 29 may be electrically connected to the controller 60 of the water purifier 100, and the air intake control valve 29 may be in an open state by default. The controller 60 may be used to receive signals and control the opening and closing of the intake control valve 29.

For ease of understanding, the following examples may be used to illustrate:

the first predetermined time period may be selected to be 10s, the second predetermined time period may be selected to be 15min, the third predetermined time period may be selected to be 8min, the fourth predetermined time period may be selected to be 10min, and the fifth predetermined time period may be selected to be 5 min. The first predetermined flow rate may be selected to be 0.6L/min, the second predetermined flow rate may be selected to be 1.05L/min, and the third predetermined flow rate may be selected to be 1.5L/min. The values of the predetermined time period and the predetermined flow rate may be set to other suitable values in practice, and are not particularly limited herein.

The air intake control valve 29 may default to an open state, and the controller 60 may not need to activate control when the user is not using bubble water, or when the user is using bubble water for less than 10 seconds.

When the user uses the bubble water for more than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the air intake control valve 29 according to the flow rate detection data. Under the condition that the flow of bubble water is less than or equal to 0.6L/min, the controller 60 can close the air inlet control valve 29, so that the air mixing tank 23 only feeds water and does not feed air, the water level of the air mixing tank 23 is ensured to be at the peak value under the condition of low flow, and the problem of air injection caused by water shortage of the air mixing tank 23 is avoided.

When the user uses the bubble water for more than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the air intake control valve 29 according to the flow rate detection data. In the case where the flow rate of the bubble water is greater than 0.6L/min and less than or equal to 1.05L/min, the controller 60 may close the intake control valve 29 for 15min and then open the intake control valve 29, and then the controller 60 may perform flow rate detection again after 8min from the opening of the intake control valve 29.

Therefore, the air mixing tank 23 can only feed water and does not feed air within 15min, and the air mixing tank 23 can be fully filled with the air mixing tank 23 within 15min under the condition of low flow; then the 8min air inlet control valve 29 is opened, the air suction of the air mixing tank 23 is larger than that of the water inlet, the water level of the air mixing tank 23 is reduced, and the water level is reduced to 1/3 water level of the air mixing tank 23 after 8 min. The reason why the closing time is longer than the opening time is to ensure that the water level of the gas mixing tank 23 is reduced to 1/3 from the peak value every time, and the gas injection situation cannot occur.

When the user uses the bubble water for more than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the air intake control valve 29 according to the flow rate detection data. In the case where the flow rate of the bubble water is greater than 1.05L/min and less than or equal to 1.5L/min, the controller 60 may close the intake control valve 29 for 10min and then open the intake control valve 29, and then the controller 60 may perform flow rate detection again 5min after the intake control valve 29 is opened.

Therefore, the air mixing tank 23 can only feed water and does not feed air within 10min, and the air mixing tank 23 can be fully filled with the air mixing tank 23 within 10min under the condition of low flow; then the air inlet control valve 29 is opened for 5min, the air suction of the mixed air tank 23 is larger than that of the inlet water, the water level of the mixed air tank 23 is reduced, and the water level is reduced to 1/3 water level of the mixed air tank 23 after 5 min. The reason why the closing time is longer than the opening time is to ensure that the water level of the gas mixing tank 23 is reduced to 1/3 from the peak value every time, and the gas injection situation cannot occur.

When the user uses the bubble water and the using time is longer than 1.5L/min, the controller 60 detects the flow of the bubble water and controls the opening and closing of the air inlet control valve 29 according to the flow detection data. The controller 60 keeps the air intake control valve 29 open, so that the air intake of the air mixing tank 23 and the water intake are kept balanced, and the micro-bubble water can be normally output.

In summary, the principle of the water purifier 100 for realizing the water outlet of the whole machine is as follows:

when the bubble water function is turned on, and the bubble water outlet 220 is in an open state, the faucet at the bubble water outlet 220 may transmit a signal to the controller 60 through hall sensing. The fourth control valve 114 on the water purification circuit board 11 is closed, the air inlet control valve 29 on the bubble water module 20 is opened, the water pump 12 is started, the fifth control valve 221 on the bubble water circuit board 21 is opened, the ejector 24 sucks air, the water and vapor are mixed in the air mixing tank 23, and the bubble water outlet 220 of the bubble water circuit board 21 realizes bubble water outlet through the pressure stabilizing release of the bubbler 231.

In the process of starting the bubble water function, the flow meter 50 can judge the water inlet flow rate before the water flow enters the gas mixing tank 23, so that the control panel 60 can be matched to control the on-off of the air inlet control valve 29.

The gas stops entering the gas mixing tank 23, so that the water quantity in the gas mixing tank 23 can be kept in a stable state, and the gas injection phenomenon cannot be generated.

When the bubble water function is turned off and the bubble water outlet 220 is in an open state, the faucet at the bubble water outlet 220 may transmit a signal to the controller 60 through hall sensing. The air inlet control valve 29 on the bubble water module 20 is closed, the fourth control valve 114 on the water purification circuit board 11 is opened, and the water pump 12 is started.

When the second pure water outlet 211 is opened, the tap at the second pure water outlet 211 transfers a signal to the controller 60 by hall sensing. The fourth control valve 114 on the water purification circuit board 11 is opened, the air inlet control valve 29 on the bubble water module 20 is closed, and the water pump 12 is started. The third control valve 218 on the bubble water passage plate 21 is opened, the fifth control valve 221 is closed, and the first control valve 212 is opened, so that the second pure water outlet 211 on the bubble water passage plate 21 discharges pure water.

When the third pure water outlet 213 is opened, the pressure after the first check valve 14 is decreased, and the high pressure switch 15 detects the pressure decrease and transmits information to the controller 60. The fourth control valve 114 on the water purification circuit board 11 is opened, the air inlet control valve 29 on the bubble water module 20 is closed, and the water pump 12 is started. The third control valve 218 on the bubble water passage plate 21 is opened, the fifth control valve 221 is closed, and the first control valve 212 is opened, so that pure water can be discharged from both the second pure water outlet 211 and the third pure water outlet 213 on the bubble water passage plate 21.

When the second waste water outlet 214 is normally open, the second pure water outlet 211 is opened and the third pure water outlet 213 is opened, the second control valve 113 on the pure water circuit board 11 is in an open state, and the second control valve 113 can control the second waste water outlet 214 on the second water circuit board 21 to open for water discharge.

All of the above water discharge states can pass through the purified water circuit board 11 and the bubble water circuit board 21, wherein the connection relationship is communicated through the above pipelines. The water purification circuit board 11 and the bubble water circuit board 21 can realize the water purification function of the water purifier 100 in the water purification module 10 by matching corresponding control valves and corresponding pipelines.
