The positions corresponding to the water inlet 223, the first water outlet 221 and the second water outlet 222 on the board 1 are respectively provided with a water inlet interface 13, a first interface 11 and a second interface 12, the water inlet 223, the first water outlet 221 and the second water outlet 222 are respectively connected with the water inlet interface 13 , the first interface 11 and the second interface 12 . The water inlet 223, the first water outlet 221 and the second water outlet 222 are all connected with the bottom surface of the filter element cover 22 facing the filter element body 21, so that after the filter element cover 22 is sealed with the filter element body 21, the water inlet 223, the first water outlet 221 Both the second water outlet 222 and the second water outlet 222 can communicate with the inside of the filter element body 21 . When the waterway plate 1 is placed horizontally and the filter element body 21 is cylindrical, the filter element 2 is detachably installed horizontally on the waterway plate 1 so that the axis of the filter element body 21 is parallel to the waterway plate 1; the water inlet 223 on the filter element cover 22 , the first water outlet 221 and the second water outlet 222 are arranged vertically downward, so that the water outlet 223 , the first water outlet 221 and the second water outlet 222 are perpendicular to the water channel plate 1 .

The working principle of the filter device provided in this embodiment is as follows: first, a filter membrane is installed in the filter element body 21 to ensure that the pure water obtained after the raw water is filtered through the filter membrane can flow out through the first water outlet 221, and the concentrated water can pass through the second water outlet. The water outlet 222 flows out; then the filter element cover 22 is sealed and connected to one end of the filter element body 21, so that an airtight space is formed inside the filter element body 21; 223. The first water outlet 221 and the second water outlet 222 are respectively connected to the water port 13, the first port 11 and the second port 12, and the water inlet 223 is connected to the raw water; when the filter device starts to work, the raw water passes through the water inlet 223 It flows into the inside of the filter element body 21, and the filter membrane filters the raw water, and the filtered pure water flows out from the first water outlet 221, and the substances that are enriched in the raw water and impermeable to the raw water form concentrated water.

The problem of high TDS (Total Dissolved Solids) value at the pure water end caused by immersion in concentrated water during work can effectively improve water quality.

In this embodiment, the filter membrane is a reverse osmosis membrane. When a pressure greater than the osmotic pressure is applied on the side of the concentrated solution, the flow direction of the solvent will be opposite to the original osmosis direction, starting from the concentrated solution through the reverse osmosis membrane to the reverse osmosis membrane. The dilute solution flows on one side, so impurities such as inorganic ions, bacteria, viruses, organic matter and colloids in raw water can be effectively removed through the reverse osmosis membrane, thereby obtaining high-quality pure water.
