The tank 30 contains a filter material, which is usually quartz stone or medical stone.

The water treatment apparatus has the following flow paths of the water paths in three states, namely a water purification state, a backwashing state and a normal washing state.

In the clean water condition, the cartridge 2 is in the first position 100. At this time, the first annular groove 21 communicates the second cavity passage 33 and the third cavity passage 34, and the first passage port 4 and the second passage port 5 are both in the closed state. Because the third cavity channel 34 is communicated with the water inlet 11, the second cavity channel 33 is communicated with the first flow channel 15, the second flow channel 16 is communicated with the water outlet 12, and water sequentially passes through the water inlet 11, the third cavity channel 34, the second cavity channel 33, the first flow channel 15, an inner cavity (the outer side of the central tube 40) of the tank body 30, the filter material in the tank body 30 and the central tube 40, and finally reaches the water outlet 12 through the second flow channel 16, so that the filtration of the incoming water is realized.

The backwash state, valve element 2 is in the second position 200. At this time, the first annular groove 21 communicates the first cavity passage 32 and the second cavity passage 33, and the first passage port 4 is opened and the second passage port 5 is closed. Because the first cavity channel 32 is communicated with the sewage draining exit 13, the second cavity channel 33 is communicated with the first flow channel 15, water sequentially passes through the water inlet 11, the third cavity channel 34, the first channel opening 4, the second flow channel 16, the central tube 40, the filter material in the tank body 30, the inner cavity of the tank body 30 (the outer side of the central tube 40) and the first flow channel 15, and finally reaches the sewage draining exit 13 through the first cavity channel 32, and other pollutants such as colloid, silt, rust and the like are washed out of the tank body 30.

In the forward wash condition, the valve cartridge 2 is in the third position 300. At this time, the first annular groove 21 communicates the second lumen channel with the third lumen channel, and the first passage port 4 is closed and the second passage port 5 is opened. Because the second annular groove 22 communicates the first cavity 32 channel with the valve core flow channel 23, water sequentially passes through the water inlet 11, the third cavity channel 34, the second cavity channel 33, the first flow channel 15, the inner cavity of the tank body 30 (the outer side of the central tube 40), the filter material in the tank body 30, the central tube 40, the second flow channel 16, the valve core flow channel 23, the second annular groove 22 and the first cavity channel 32, finally reaches the sewage outlet 13, and further washes away other impurities such as filter material powder.

In the backwashing state and the normal washing state, although the second flow passage 16 is always communicated with the water outlet 12, water does not flow out of the water outlet 12. This is because the user is usually in a state of no water when performing the back washing or the front washing, which corresponds to the water outlet 12 being closed.
