As a preferred embodiment of the present application, as shown in fig. 1 to 3 and 11, the housing 1 includes a first end cap 11 and a second end cap 12, the first end cap 11 and the second end cap 12 are detachably connected to form a space for accommodating the filter unit 2, the raw water inlet 121, the raw water outlet 122 and the purified water outlet 123 are all disposed on the second end cap 12, the rotating member 4 is rotatably disposed on the second end cap 12, the filter unit 2 includes a filter element 22 and a mounting head 23, a sealing ring rib 127 is disposed in the second end cap 12, the purified water outlet 123 is disposed inside the sealing ring rib 127, the raw water outlet 122 is disposed outside the sealing ring rib 127, and the mounting head 23 is in sealing engagement with the sealing ring rib 127. It will be appreciated by those skilled in the art that by removably connecting the first end cap 11 and the second end cap 12, the cartridge 22 is conveniently exposed by being separated when the cartridge 22 is replaced. Specifically, as shown in fig. 3, 11 and 12, the present application schematically illustrates an embodiment in which the first end cap 11 is provided with a turnbuckle slot 111, and the second end cap 12 is provided with a turnbuckle protrusion 128, and the first end cap 11 and the second end cap 12 are detachably connected by screwing the turnbuckle slot 111 and the turnbuckle protrusion 128. When the filter unit 2 is mounted in place, the mounting head 23 and the sealing ring rib 127 are in sealing fit, so that the purified water channel 21 is in sealing butt joint with the purified water outlet 123, and purified water and raw water channeling are prevented, and at this time, a gap formed between the outer side of the filter element 22 and the inner wall of the housing 1 forms the raw water channel 3. Preferably, a stop rib 129 can be arranged on the inner side of the sealing ring rib 127, and the stop rib 129 is propped against the mounting head 23, so that the mounting head 23 is kept at a certain distance from the end face of the shell 1, where the purified water outlet 123 is arranged, and the cross-sectional area of a flow passage is further ensured, and the water flow rate is increased.

The application can be realized by adopting or referring to the prior art at the places which are not described in the application.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
