After the tap water enters the main unit 1, the tap water firstly passes through the four-sided valve 130, then passes through the filtering component 120, the purified water passes through the check valve 150, and then flows into the purified water cavity 111 of the pressure barrel 110 through the purified water pipeline of the four-sided valve 130, the check valve 150 can prevent the water in the pressure barrel 110 from flowing back, the effect of suppressing the pressure inside the pipeline is achieved, and therefore the four-sided valve 130 can normally work. The four-side valve 130 is used for cutting off the raw water supply through the internal mechanical structure when the pressure in the purified water pipeline reaches a certain pressure, so that the effect of stopping the water supply when the purified water pipeline is full of water is achieved.
In this embodiment, the filter assembly 120 includes a first filter element 121, a second filter element 122 and a third filter element 123 which are serially connected in sequence, an outlet end of the third filter element 123 is communicated with the purified water chamber 111, and the purified water enters the purified water chamber 111. In other embodiments of the present invention, the structure and type of the filter assembly 120 may also be configured according to actual purification requirements.
Specifically, when the extension unit 2 is connected to the main body unit 1, the booster pump 210 is located between the primary filter element 121 and the secondary filter element 122, and when the main body unit 1 is connected to the extension unit 2, the water path direction is changed, so that the booster pump 210 boosts the pressure of the pipeline, and the water purifier becomes an electrically driven type, and the water pressure of raw water is not required.
