[0035] In the prior art, the filter element of the water purifier can filter tap water and provide users with filtered pure water. However, the pure water filtered by the filter element is stored in a pure water tank for a long time without being used, which is easy to breed bacteria, affecting the working performance of the water purifier and the user's experience.

[0036] In order to overcome the problems in the prior art, the present embodiment provides a microbubble generator (32) at the water inlet end of the pure water tank (40). A sufficient amount of bubbles are generated by the microbubble generator (32) and enter the pure water tank (40). The bubbles will continue to exist in the pure water tank (40) for a period of time and then burst to generate hydroxyl free radicals, which can remove microorganisms and organic micropollutants in the water in the pure water tank (40) and effectively ensure the safety of water quality.

[0037] In a more preferred embodiment, a flushing waterway (70) is provided between the pure water waterway (30) and the waste water waterway (60), and the flushing waterway (70) is provided with a flushing valve (71). Since the RO membrane filter element (20) needs to be flushed to ensure the filtering effect when it is installed for the first time or is not used for a long time, the water after flushing enters the pure water tank (40) and cannot be used for drinking by users, and needs to be discharged from the waste water outlet (61). In this embodiment, a flushing waterway (70) is provided between the pure water waterway (30) and the waste water waterway (60), so that the pure water generated by flushing the RO membrane filter element (20) is directly discharged to the waste water outlet (61) along the flushing waterway (70), so as to flush the RO membrane filter element (20).

[0038] In a more preferred embodiment, the drainage waterway (50) is provided with a one-way valve (D) to ensure that the water in the pure water tank (40) flows in one direction toward the drain outlet (51), thereby preventing the water in the drainage waterway (50) from flowing back into the pure water tank (40) and causing pollution.

[0039] In a more preferred embodiment, a liquid level sensor (41) is provided in the pure water tank (40) to detect the water level in the pure water tank (40);

[0040] When the water level in the pure water tank (40) is lower than a preset water level value, the water inlet valve (12), the booster pump (13) and the pure water valve (31) are opened, and the RO membrane filter element (20) continuously produces pure water which is stored in the pure water tank (40);

[0041] When the water level in the pure water tank (40) is higher than a preset water level value, the water inlet valve (12), the booster pump (13) and the pure water valve (31) are closed, and the drainage pump (52) is turned on to drain the water in the pure water tank (40) to the drainage port (51).

[0042] In this embodiment, the water level in the pure water tank (40) is detected by a liquid level sensor (41), thereby controlling the working state of each valve to ensure a continuous and large amount of pure water supply to the user.

[0043] In a more preferred embodiment, the water inlet waterway (10), the pure water waterway (30), and the drainage waterway (50) are respectively provided with flow meters (L) to measure the water flow. The flow of each waterway is detected by the flow meter (L), thereby adjusting the power of the booster pump (13) to ensure the stability of the water flow.

[0044] In a more preferred embodiment, a TDS probe (T) is provided in the water inlet circuit (10) and the pure water tank (40) to detect the TDS value of the water. When the TDS value of the water in the water inlet circuit (10) or the pure water tank (40) exceeds the corresponding preset value, an alarm is issued to ensure the safety of drinking water. Specifically, when the TDS value of the water in the pure water tank (40) exceeds the corresponding preset value, the water in the pure water tank (40) can be discharged to the wastewater outlet (61) through the flushing circuit (70).

[0045] In a more preferred embodiment, a pre-filter element (14) is provided at the water inlet (11) to preliminarily filter the water entering the water inlet waterway (10). In this embodiment, the pre-filter element (14) is used to preliminarily filter large particles of impurities in the tap water to protect the RO membrane filter element (20). Specifically, the utility model does not limit the specific model of the pre-filter element (14), and those skilled in the art can use any known filter element, such as one or more of a PP cotton filter element, an activated carbon filter element, a polypropylene spray-melt filter element, and a coconut shell particle filter element.

[0046] In a more preferred embodiment, the water inlet circuit (10) is provided with a temperature sensor (15) to detect the temperature of water entering the water inlet circuit (10).

[0047] In a more preferred embodiment, the drainage waterway (50) is provided with a pressure switch (53) to ensure the drainage stability of the drainage outlet (51).

[0048] In a more preferred embodiment, the pure water tank (40) is provided with an air inlet (42) and an exhaust port (43), a HEPA filter (421) is provided at the air inlet (42), and a one-way valve (D) is provided at both the air inlet (42) and the exhaust port (43). In this embodiment, the air inlet (42) and the exhaust port (43) are provided in the pure water tank (40) to maintain the pressure balance inside and outside the pure water tank (40), thereby preventing the pure water tank (40) from leaking due to long-term pressure imbalance. A HEPA filter (421) is provided at the air inlet (42) to filter the gas entering the pure water tank (40), thereby preventing the water in the pure water tank (40) from being contaminated. A one-way valve (D) is provided at the air inlet (42), so that the water in the pure water tank (40) cannot flow out from the air inlet (42). A one-way valve (D) is provided at the exhaust port (43). When the liquid level sensor (41) in the pure water tank (40) fails and becomes full of water, the water in the pure water tank (40) is discharged along the exhaust port (43).
