Referring to fig. 8, in some embodiments, the bubble water module 20 includes an air inlet control valve 29, the air inlet control valve 29 is used for controlling the amount of air entering the bubble water module 20, the water purifier 100 includes a controller 60 connected to the air inlet control valve 29, the controller 60 is used for obtaining the flow rate of the bubble water when the duration of the air flowing out of the water purifier 100 is greater than a first predetermined duration, and controlling the air inlet control valve 29 to be closed when the flow rate of the bubble water is less than or equal to the first predetermined flow rate.

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 second predetermined period of time and then open the air intake control valve 29 when the flow rate of the bubble water is greater than the first predetermined flow rate and less than or equal to the second predetermined flow rate, and re-acquire the flow rate of the bubble water after the air intake control valve 29 is restarted for a third predetermined period of time, where the second predetermined period of time is greater than the third predetermined period of time, and the third predetermined period of time is greater than the first predetermined period of time.

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 and then to open the air intake control valve 29 when 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, 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.

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

Thus, the controller 60 can control the air inlet control valve 29 by detecting the use time of the bubble water and the flow rate of the bubble water, and can take different control operations according to different situations of the user taking the bubble water, thereby improving the use experience of the water purifier 100.

Specifically, the air intake control valve 29 may be disposed between the air intake 241 of the bubble water module 20 and the bubble water outlet 220, the air intake control valve 29 may be an air intake electromagnetic control valve, the air intake control valve 29 may be electrically connected with the controller 60 of the water purifier 100, and the air intake control valve 29 may be in an opened state by default. The controller 60 is operable 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 5min. 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, without being particularly limited thereto.

The inlet control valve 29 may be in an open state by default, and the controller 60 may not need to initiate 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 and the use time is longer than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the intake control valve 29 based on the flow rate detection data. When the flow rate of the 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 inlets water and does not enter air, the water level of the air mixing tank 23 can be ensured to be at a peak value under the condition of low flow rate, and the problem that the air mixing tank 23 does not have water and is injected is avoided.

When the user uses the bubble water and the use time is longer than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the intake control valve 29 based on 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 of opening the intake control valve 29.

Thus, the air mixing tank 23 can be ensured to only intake water and not intake air within 15min, and the air mixing tank 23 can be ensured to be filled with the air mixing tank 23 within 15min under the condition of low flow; then the air inlet control valve 29 is opened for 8min, 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 air mixing tank is reduced to 1/3 of the water level of the air mixing tank 23 after 8 min. The closing time is longer than the opening time to ensure that the water level of the air mixing tank 23 is reduced from the peak value to 1/3 every time, and no air injection occurs.

When the user uses the bubble water and the use time is longer than 10 seconds, the controller 60 detects the flow rate of the bubble water, and controls the opening and closing of the intake control valve 29 based on 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 after 5min of opening the intake control valve 29.

Thus, the air mixing tank 23 can be ensured to only intake water and not intake air within 10min, and the air mixing tank 23 can be ensured to be 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 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 air mixing tank is reduced to 1/3 of the water level of the air mixing tank 23 after 5 min. The closing time is longer than the opening time to ensure that the water level of the air mixing tank 23 is reduced from the peak value to 1/3 every time, and no air injection occurs.

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

When the second pure water outlet 211 is opened, the tap at the second pure water outlet 211 transmits a signal to the controller 60 through hall sensing. The fourth control valve 114 on the purified water path plate 11 is opened, the air intake 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 waterway 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 waterway plate 21 discharges pure water.

The fourth control valve 114 on the purified water path plate 11 is opened, the air intake 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 waterway 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 and the third pure water outlet 213 on the bubble water waterway plate 21 can both discharge pure water.

The second waste water outlet 214 is normally open, and when the second pure water outlet 211 is opened and the third pure water outlet 213 is opened, the second control valve 113 on the water purifying waterway plate 11 is in an opened state, and the second control valve 113 can control the second waste water outlet 214 on the second waterway plate 21 to open the water discharge.

All the above water outlet states can be communicated through the purified water waterway plate 11 and the bubble water waterway plate 21, wherein the connection relationship is communicated through the above pipelines. The water purifying channel plate 11 and the bubble water channel plate 21 can be matched with each other through corresponding control valves and corresponding pipelines to realize the water purifying function of the water purifier 100 in the water purifying module 10.
