The filter element assembly 2 can adopt the existing technology, which will not be elaborated here; the first clean water tank 3 is also connected to the fourth pipeline 54, and the fourth pipeline 54 is provided with a water pump 65 and a heater 66, and the outlet of the fourth pipeline 54 corresponds to the hot water outlet of the water purification equipment.

[0025] In addition, the filter element assembly 2 is also connected to the raw water tank 7 through a waste water pipe 55, and a waste water valve 67 is provided on the waste water pipe 55. The clean water pipeline 1 is also provided with a one-way valve 68 located between the filter element assembly 2 and the first clean water tank 3 to prevent the water in the first clean water tank 3 from flowing back into the filter element assembly 2.

[0026] The humidifier 4 includes a second clean water tank 42 and an atomizer (not shown in the figure). The atomizer is a commonly used component in the humidifier 4. This embodiment only involves the improvement of the water circuit in the humidifier 4, and does not improve it. The second clean water tank 42 has a water inlet 41 connected to the first clean water tank 3. In this embodiment, the first clean water tank 3 is connected to the water inlet 41 of the second clean water tank 42 through a second pipe 52, and the second pipe 52 is provided with a second valve 63 for controlling the opening or closing of the second pipe 52; in addition, the water outlet of the second clean water tank 42 is connected to the upstream of the filter element assembly 2 of the clean water pipeline 1 through the first pipe 51 (such as Figure 1 The outlet of the first pipe 51 is connected to the raw water tank 7), a drainage pump 61 is provided on the first pipe 51, and a first valve 62 for controlling the opening or closing of the first pipe 51 is also provided on the first pipe 51. In addition, the second clean water tank 42 is also connected to a fifth pipe 55, the outlet of the fifth pipe 55 corresponds to the mist outlet 1a, and the first valve 62 and the second valve 63 are both solenoid valves.

[0028] In addition, the water purification equipment also includes a first liquid level detection module for detecting the water level in the communicating vessel 8 and a second liquid level detection module for detecting the water level in the raw water tank 7. The above-mentioned first liquid level detection module and second liquid level detection module can detect the liquid level by means of a probe or a float. The liquid level detection method is an existing technology and will not be elaborated here.

[0029] The working process of the water purification equipment in this embodiment is as follows:

[0030] Power-on flushing process:

[0031] After the water purification device is powered on, it first detects whether the raw water tank 7 is in place and whether the liquid level in the raw water tank is greater than the low water level and less than the middle water level. If the raw water tank 7 is in place and the liquid level meets the requirements, the water pump 64 and the waste water valve 67 are turned on, and the filter element assembly 2 is rinsed with water in the raw water tank 7; if the liquid level in the raw water tank 7 is higher than the middle water level, the water purification device has an alarm reminder to remind the user to pour out part of the water in the raw water tank 7, and no action is taken at the same time; if the liquid level in the raw water tank 7 is less than the low water level, the filter element assembly 2 is not rinsed, and the water purification device needs to remind the user to add water until the liquid level in the raw water tank 7 meets the preset requirements;

[0032] Water production process:

[0033] After the power-on flushing is completed, the water purification device needs to continue to detect whether the liquid level in the raw water tank 7 is greater than the low water level and less than the middle water level, and at the same time detect whether the liquid level in the communicating vessel 8 is less than the low water level. If the above requirements are met, the water production logic is performed, that is, the water pump 64 is turned on; if the liquid level in the raw water tank 7 is less than the low water level at this time, the water purification device enters the water replenishment logic of the raw water tank 7, and continues to produce water until the water level in the raw water tank 7 meets the above requirements. If the liquid level in the communicating vessel 8 reaches the high water level, the water production is stopped; as long as the liquid level in the communicating vessel 8 reaches the low water level, the second valve 63 will be opened, so that the clean water in the first clean water tank 3 will be replenished into the second clean water tank 42 until the liquid levels in the two clean water tanks are at the same height;

[0034] Humidification process:

[0035] Detect whether the liquid level in the communicating vessel 8 is greater than the low water level, and at the same time, detect whether the hygrometer is a preset value of the system, which can be set by the user; if the condition is met at this time, turn on the atomizer of the humidifier; if the liquid level in the communicating vessel 8 is lower than the low water level, then enter the water production process;

[0036] Water extraction process:

[0037] When receiving the water taking signal, it is first necessary to detect whether the water level in the communicating vessel 8 is greater than the low water level. If the condition is not met, the water making process is entered; if the condition is met, it is necessary to continue to identify whether to take normal temperature water or hot water; if it is normal temperature water, the water pump 65 and the disinfection lamp 69 are started at this time; if it is hot water, the water pump 65 and the heating body 66 are started at this time; if it is hot water of other temperatures, the power of the heating body 66 is controlled to heat hot water of different temperatures;

[0038] Drainage process:

[0039] When it is detected that the humidifier 4 has not been used for a preset time, which is generally set to 3 days, the drainage process will be executed; before drainage, it is necessary to first detect whether the liquid level in the raw water tank 7 is less than the middle water level, and also to detect whether the liquid level in the communicating vessel 8 is the low water level in real time. If the water level in the communicating vessel 8 is greater than the low water level and less than the high water level, and the liquid level in the raw water tank 7 is less than the middle water level, then the drainage logic will be executed, that is, the drainage pump 61 and the first valve 62 will be opened; when the liquid level in the raw water tank 7 reaches the high water level or the liquid level in the communicating vessel 8 is less than the low water level, the drainage will be stopped; if the liquid level in the raw water tank 7 is the high water level and the liquid level in the communicating vessel 8 is greater than the low water level 2, then the drainage will also be stopped first, that is, the drainage pump 61 and the first valve 62 will be closed, and the user will be reminded to pour out part of the water in the raw water tank 7, and the water level in the raw water tank 7 will be controlled to be greater than the low water level and less than the middle water level, and the raw water tank 7 will be detected again, and then the drainage will continue. When the drainage logic is executed, the system enters the water making mode.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
