The operator can seal each drain outlet through the sealing element 5, which is convenient to operate and facilitates rapid drainage and sealing.

[0038] like Figures 3-8 As shown, an inlet pipe 21 is integrally installed on the water system base 2. The outlet end of the inlet pipe 21 is connected to the inlet end of the booster pump 3. The first drain outlet 211 is connected to the inlet pipe 21. Integrating the inlet pipe 21 into the water system base 2 reduces the possibility of pipe loosening and facilitates the firmness and reliability of the water system connection. The inlet pipe 21 is equipped with a TDS detection device 212, which can monitor the water quality in the inlet pipe 21 in real time, allowing the operator to promptly access the water through the first drain outlet 211. The liquid in the inlet pipe 21 is discharged; a connecting pipe 22 is integrally provided on the water base 2, and the outlet of the booster pump 3 is connected to the inlet of the filter device 4 through the connecting pipe 22. The second drain outlet 221 is connected to the connecting pipe 22. The connecting pipe 22 is integrally set on the water base 2, which reduces the possibility of pipe loosening and is conducive to the firmness and reliability of the water connection; the filter device 4 includes a filter shell 41 and a filter element module 42 disposed in the filter shell 41. In this embodiment, the filter element module 42 includes a pre-filter. In zones 421 and 422, water discharged from the outlet of booster pump 3 flows into 422 after being filtered through pre-filtration zone 421. The purified water from 422 flows to purified water outlet 401, while the wastewater from 422 flows to wastewater outlet 402. Filter housing 41 is integrally formed on the water circuit base 2. Purified water from filter module 42 flows to purified water outlet 401, and wastewater from filter module 42 flows to wastewater outlet 402. The filter housing 41 is integrally mounted on the water channel base 2, which can prevent water leakage between the filter device 4 and the water channel base 2 due to the joint, and greatly improve the water leakage prevention performance of this utility model. The water channel base 2 is integrally provided with a wastewater pipe 23. The inlet end of the wastewater pipe 23 is connected to the wastewater outlet end 402 of the filter device 4, and the third drain outlet 231 is connected to the wastewater pipe 23, which improves the water leakage prevention between the wastewater pipe 23 and the water channel base 2 and prevents the wastewater pipe 23 from shaking relative to the water channel base 2.

[0039] A type of water purifier, such as Figures 1-8 As shown, the system includes a water tank 6 and a water purifier body 1. The water purifier body 1 has a drainage structure. The water tank 6 is connected to the inlet of the booster pump 3 via a raw water pipe 61. The wastewater outlet 402 is connected to the water tank 6 via a return water pipe 62. The wastewater discharged from the wastewater outlet 402 can be recycled back to the water tank 6 via the return water pipe 62.

The water purifier body 1 has an integrated inlet connection pipe 13 and a return water connection pipe 14. The outlet of the raw water pipe 61 is connected to the inlet pipe 21 via the inlet connection pipe 13. The outlet of the wastewater pipe 23 is connected to the return water pipe 6 via the return water connection pipe 14. 2. The water tank 6 is equipped with a pre-treatment filter element 63, which is connected to the inlet end of the raw water pipeline 61. The pre-treatment filter element 63 can filter and purify the raw water entering the inlet end of the booster pump 3, reducing the filtration burden of the filter device 4 and thus extending the service life of the filter device 4. The water purifier body 1 is equipped with a water outlet 11, the inlet end of the water outlet 11 is connected to the purified water outlet 401, and a UV sterilization device 12 is provided between the purified water outlet 401 and the water outlet 11. In addition, the purified water outlet 401 is also equipped with a TDS detector. The UV sterilization device 12 can sterilize the water at the inlet end of the water outlet 11, thereby improving the safety of the purified drinking water of this utility model.

[0040] The basic working principle of this utility model is as follows: An inlet pipe 21, a connecting pipe 22, a wastewater pipe 23, and a filter housing 41 are integrally formed on the water circuit base 2. A booster pump 3 is installed inside the water purifier body 1, and a filter element module 42 is installed inside the filter housing 41. Simultaneously, the water circuit base 2 is provided with a first drain outlet 211 connecting to the inlet pipe 21, a second drain outlet 221 connected to the connecting pipe 22, and a third drain outlet 231 connected to the wastewater outlet 402 of the filter device 4. When the water purifier is not used for a long time, to prevent the booster pump 3 and the filter from malfunctioning... Since residual water in device 4 can easily lead to bacterial growth, the operator can use the first drain port 211 to drain the water from the inlet of the booster pump 3, the second drain port 221 to drain the water from the outlet of the booster pump 3 and the inlet of the filter device 4, and the third drain port 231 to drain the water from the wastewater outlet 402 of the filter device 4. In this way, the operator can use the corresponding multiple drain ports of this utility model to drain the residual water in the booster pump 3 and the filter device 4, which has the effect of zero residual water to avoid bacterial growth and convenient transportation.
