There are four groups of guide blocks 806, and the four groups of guide blocks 806 are arranged in a circular array with the center point of the cover plate 2. A return spring 807 is fixed to the side wall of the guide block 806. The side of the return spring 807 away from the guide block 806 is fixed to the inner wall of the slide groove 805. The return spring 807 can be set to reset the guide block 806. An inclined block 808 is fixed to the side of the guide block 806 close to the fixed sleeve 801. A guide hole 7 is opened on the inner side of the filter housing 1. The inner wall of the guide hole 7 is in contact with the outer wall of the guide block 806. A plurality of groups of equidistant blocks 812 are fixed to the inner side of the guide block 806, and the PP filter screen 5 and the activated carbon filter screen 6 are in contact with the outer wall of the block 812. The PP filter screen 5 and the activated carbon filter screen 6 are fitted together, and the block 812 is set to limit the PP filter screen 5 and the activated carbon filter screen 6. The side wall of the filter housing 1 passes through the limit rod 809, and the limit rod 809 is slidably connected to the penetration of the filter housing 1. The end of the limit rod 809 is fixed with a handle 810, and the side wall of the handle 810 is fixed with a connecting spring 811.

[0029] Working principle: When the PP filter 5 and the activated carbon filter 6 need to be replaced and cleaned, the handle 810 can be pulled to move the limiting rod 809 out of the limiting hole 813, thereby releasing the limit on the cover plate 2, and the cover plate 2 can be removed from the filter housing 1, and the filter can be taken out of the filter housing 1, so that the guide block 806 is moved out of the guide hole 7, and by reversing the rotating block 802, the squeezing block 804 will squeeze the inclined surface of the four groups of inclined blocks 808, so that the inclined blocks 808 will be subjected to squeezing force, so that the four groups of inclined blocks 808 are separated from each other, and the inclined blocks 808 squeeze the four groups of guide blocks 806 away from each other, so that the block 812 will not block and limit the filter, which can facilitate the PP filter 5 and the activated carbon filter 6. The filter 5 and the activated carbon filter 6 are disassembled for easy replacement and cleaning. When the PP filter 5 and the activated carbon filter 6 need to be installed, the rotating block 802 can be reversed to make the extrusion block 804 squeeze the inclined block 808 away from each other, and the guide block 806 drives the card block 812 away from each other, and the PP filter 5 and the activated carbon filter 6 are placed between the card blocks 812. By loosening the rotating block 802, since the spring 803 is in a contracted state, the four groups of guide blocks 806 can squeeze and fix the PP filter 5 and the activated carbon filter 6, so that the PP filter 5 and the activated carbon filter 6 are stuck in the card block 812, which is convenient for the installation of the PP filter 5 and the activated carbon filter 6.

[0030] When the PP filter 5 and the activated carbon filter 6 are taken out, the scraper 93 can be moved in contact with the inner wall of the filter housing 1 to clean the inner wall of the filter housing 1 and scrape off the scale and the like attached to the inner wall of the filter housing 1 .

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
