In order to prevent water in the raw water chamber 111 from overflowing the partition into the waste water chamber 112 or water in the waste water chamber 112 from overflowing the partition into the raw water chamber 111, the present application provides at least the following three specific embodiments to solve the problem, specifically the following first embodiment, second embodiment, and third embodiment.

The first embodiment: the water level detection module 152 in the above embodiment is disposed in the waste water chamber 112, and can prompt the user to treat waste water when the water level in the waste water chamber 112 reaches the preset water level, or the water purification mechanism 100 stops working when the water level in the waste water chamber 112 reaches the preset water level, and then stops generating waste water.

Referring to fig. 2, a second embodiment: the water entering the filter element assembly 130 is preheated, so that the temperature of the water entering the filter element assembly 130, particularly the water entering the reverse osmosis post-filter element 132 reaches a preset temperature, the filter element speed of the reverse osmosis post-filter element 132 is greatly influenced by the temperature, when the temperature is low (3-15 ℃), the water filtering speed of the reverse osmosis post-filter element 132 is low, the time for filtering to obtain the same pure water is longer, the generated wastewater is more, but when the temperature is higher (15-40 ℃), the water filtering speed of the reverse osmosis post-filter element 132 is higher, the time for filtering to obtain the same volume of pure water is shorter, the generated wastewater is shorter, and the wastewater in the wastewater cavity 112 can be discharged for a longer time.

Specifically, in this second embodiment, the water purification mechanism 100 further includes a preheating assembly 171 connected between the raw water chamber 111 and the filter element assembly 130, the raw water flowing from the raw water chamber 111 to the filter element assembly 130 can be heated to a preset temperature by the preheating assembly 171, specifically, the raw water can be heated to an optimal filtering temperature of the reverse osmosis post-filter element 132, for example, the raw water is heated to about 25 degrees celsius, at this time, the water filtration rate of the reverse osmosis post-filter element 132 is higher, the time required for obtaining the same volume of pure water by filtration is less, and further, the generated wastewater is less, the wastewater can be discharged from the wastewater chamber 112 for a longer time, the frequency of treating the wastewater in the wastewater chamber 112 is reduced, and the user experience is better.

It should be noted that the optimal filtered water temperature may be different for different reverse osmosis post-filter elements 132, and the pre-heating assembly 171 in this second embodiment can adjust the pre-set temperature according to the specific reverse osmosis post-filter element 132 to improve the user experience.

Further, the preheating unit 171 may be connected between the preheating unit 171 and the filter element assembly 130, and of course, the preheating unit 171 may be connected between the raw water tank 110 and the booster pump 120.

Referring to fig. 3, in the third embodiment, the recovery rate of the waste water in the waste water chamber 112 is adjusted according to the difference of the quality of the raw water, specifically, the better the quality of the water, the less the waste water generated by filtering through the filter element assembly 130 needs to be discharged to the waste water chamber 112, and the worse the quality of the water, the more the waste water generated by filtering through the filter element assembly 130 needs to be discharged to the waste water chamber 112, so that when the better quality of the water is filtered, less waste water enters the waste water chamber 112, so that the waste water chamber 112 can store the waste water for a longer time to be discharged, the volume of the waste water chamber 112 can be properly reduced, the volume of the raw water chamber 111 can be increased, and the mechanism of the raw water tank 110 can be further optimized.
