Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically a water filter with a quick connector. Background Technology

[0002] A water purifier, also called a water filter machine or water purifier, is a water treatment device that performs deep filtration and purification of water according to usage requirements. The water purifiers commonly referred to are generally small purifiers used in homes. Their core technology lies in the filter membrane within the filter cartridge, primarily utilizing ultrafiltration membranes, RO reverse osmosis membranes, and nanofiltration membranes.

[0003] Current water purification methods utilize an integrated, sealed structure with a filter cartridge to achieve filtration and purification. However, this makes it inconvenient to replace the internal filter cartridge, and the single-cartridge structure results in insufficient filtration and purification, affecting the subsequent use of the water. Summary of the Invention

[0004] The purpose of this utility model is to provide a water filter with a quick connector to solve the problems mentioned in the background art. Current water purification treatment uses an integrated sealed structure to achieve filtration and purification through the filter element, which makes it inconvenient to replace the internal filter element. Furthermore, the single filter element structure results in insufficient filtration and purification effect, affecting the subsequent use of the water.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water filter with a quick connector includes a main housing, one end of which is threadedly connected to a top cover. A raw water inlet is fixedly connected to the end of the main housing away from the top cover, and a purified water outlet is fixedly provided at the other end. An inner support frame is fixedly snapped onto the inner side of the main housing, a PP filter element is snapped onto the inner side of the main housing, and an inner support shell is fixedly snapped onto the inner side of the main housing. A sealing ring is fitted onto the outer side of the inner support shell, and an ultrafiltration membrane filter element is filled into the inner side of the inner support shell. An activated carbon chamber is provided on the inner side of the inner support frame. A supporting bottom shell is fixedly snapped onto the bottom of the inner support shell. A mating side groove is provided on the inner side of the inner support shell, and the inner side of the mating side groove is filled with air-permeable but water-permeable membrane fibers. The inner side of the inner support shell is filled with water-permeable membrane fibers.

[0007] In a preferred embodiment of the present invention, one end of the main body shell is open, and the upper cover is threadedly fixedly connected to the outer side of the open end of the main body shell.

[0008] In a preferred embodiment of this utility model, the raw water inlet is fixedly connected to one end of the main shell near the edge, and the interior of the raw water inlet is in communication with the interior of the main shell. The connection opening of the raw water inlet is located between the inner side of the main shell and the outer side of the inner support shell.

[0009] In a preferred embodiment of this utility model: the purified water outlet is fixedly connected to the center of one end of the main body shell, and the purified water outlet is in communication with the interior of the main body shell. The connection opening end of the purified water outlet is located on the inner side of the inner support shell. The inner support frame is a mesh-like tubular structure that is snapped onto the inner side of the main body shell near the upper cover. One end of the inner support frame is connected to the edge of the upper cover, and the outer side of the inner support frame is snapped onto the sealing ring structure.

[0010] In a preferred embodiment of this utility model, one end of the PP filter element is connected to one end of the inner support frame, and the PP filter element is located between the inner side of the main shell and the outer side of the inner support shell. The inner support shell is vertically snapped onto one end of the inner central axis of the main shell.

[0011] In a preferred embodiment of this utility model: the sealing ring is sleeved on the outer end of the inner support shell, and the outer side of the sealing ring is snapped on the inner side of the main body shell. The activated carbon cavity is filled with activated carbon material. The top opening of the support bottom shell is sealed and snapped on the bottom opening of the inner support shell, and the bottom end of the support bottom shell is snapped on the central slot of the upper cover. The outer bottom end of the support bottom shell is uniformly provided with through groove structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention fixes the external raw water pipe at one end of the raw water inlet and the outlet pipe at one end of the purified water outlet. The activated carbon pack is inserted through the bottom opening of the main body shell into the movable carbon chamber inside the inner support frame, filling the chamber and wrapping the activated carbon around the outer edge of the support shell. The bottom opening of the main body shell is then sealed by the top cover. When raw water enters the area between the main body shell and the inner support shell through the raw water inlet, it undergoes initial filtration through a PP filter element. The water then enters the activated carbon chamber through the top hole of the inner support frame. It undergoes further adsorption and filtration through the internal activated carbon packing. The filtered water then enters the inner support shell through the bottom groove of the supporting base shell. After passing through an ultrafiltration membrane cartridge and a water-permeable membrane fiber for filtration and purification, the air-permeable but water-permeable membrane fiber provides a breathable effect. Finally, the filtered water is discharged through the inlet outlet. The modular structure allows for easy disassembly and replacement of the internal filter cartridges. Furthermore, the multiple filtration and purification structures enhance the filtration and purification effect. Attached Figure Description
