Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a detachable composite RO membrane water purifier filter element. Background Art

[0002] When filtering drinking water, it is generally necessary to perform multi-stage filtration (composite filtration) before it can be used for normal drinking. At present, activated carbon, PP cotton and RO membrane are generally connected in series on the water pipe to solve the comprehensive filtration of impurities in the water. Ordinary activated carbon, PP cotton and RO membrane composite filtration is generally composed of multiple filter bottles containing activated carbon, PP cotton and RO membrane respectively connected in series on the water pipe, filtering the water pipe layer by layer, which can filter the water well.

[0003] The RO membrane filter element structure mainly includes a central water production pipe and a multi-layer reverse osmosis filter membrane wrapped around the outside. The water production pipe and the multi-layer reverse osmosis filter membrane are fixedly connected. The RO membrane filter element is a relatively expensive component in the water purifier filter element. The central water production pipe and the reverse osmosis filter membrane cannot be replaced separately. When a problem occurs in one part, the entire RO membrane filter element needs to be replaced, which increases the use and maintenance costs of the water purifier and increases the financial burden on families or businesses.

At the same time, the friction sealing position in the sealing cover is sleeved on the outside of the friction sealing rubber sleeve fixed on the outer circumference of the bottom of the reverse osmosis filter membrane body.

[0008] Preferably, the bottom of the reverse osmosis membrane body and the sealing cover are sealed by a ring-shaped sealing gasket, and the top of the reverse osmosis membrane body and the water production pipe body are sealed by a sealing sleeve fixedly arranged on the top of the reverse osmosis membrane body.

[0009] Preferably, the sealing sleeve is a cylindrical structure made of rubber material, and the inner diameter of the sealing sleeve is smaller than the outer diameter of the water production pipe body. At the same time, the sealing sleeve and the water production pipe body are installed with interference fit.

[0010] Preferably, two sets of oppositely arranged positioning grooves are provided on the circumferential inner wall of the inner pipe, and two sets of oppositely arranged positioning seats are fixedly provided on the circumferential outer wall of the water production pipe body, and the sizes of the positioning seats and the positioning grooves are adapted to each other.
