Beneficial Effects

[0009] 1. The upper and lower ends of the double-layer filter of the utility model are connected to the upper filter seat and the lower filter seat. The double-layer filter, the lower filter seat and the upper filter seat form a filter cartridge. The lower filter seat tube is inserted into the lower tube of the purifier shell, so that the filter cartridge is placed in the center of the purifier shell. The purifier shell is connected to the external water pipe. The water through the external water pipe enters the inside of the purifier shell and enters the filter cartridge and is discharged downward from the lower filter seat tube. The double-layer filter filters the incoming water flow, so that impurities in the water adhere to the outside of the double-layer filter. The positioning boss is fixed on the circular upper pressure cover. The positioning boss is inserted into the inner hole of the upper filter seat, and the positioning boss assists in positioning the filter cartridge to keep the filter cartridge vertical and prevent it from shaking under the impact of water flow during water resource protection and purification. The L-shaped card plate is installed and fixed on the circular upper pressure cover. When in use, the L-shaped card plate and the arc-shaped limiting convex plate are staggered, and the circular upper pressure cover is fitted with the purifier housing, and then the circular upper pressure cover is rotated to fit the L-shaped card plate with the arc-shaped limiting convex plate. The arc-shaped limiting convex plate limits the L-shaped card plate, so that the lower surface of the circular upper pressure cover is tightly fitted with the purifier housing, preventing it from being loosened by the impact of water flow during water resource protection and purification.

[0010] 2. The sliding positioning rod of the utility model passes through the sliding hole of the upper positioning rod and is connected to the upper cap of the sliding positioning rod. The upper cap of the sliding positioning rod cooperates with the convex ring of the sliding positioning rod to prevent the sliding positioning rod from falling from the sliding hole of the upper positioning rod during water resource protection and purification. The sliding positioning rod is inserted into the double-layer filter screen. The sliding positioning rod axially positions the circular upper pressure cover. During water resource protection and purification, the circular upper pressure cover is prevented from rotating, causing the L-shaped clamping plate and the arc-shaped limiting convex plate to be disconnected and the circular upper pressure cover to loosen. When the filter cartridge needs to be taken out to clean the impurities on the outside, the sliding positioning rod is pulled upward from the double-layer filter screen, and the circular upper pressure cover can be opened by rotating the circular upper pressure cover, and the filter cartridge can be taken out from the purifier housing upward, which is easy to operate.
