[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 4The embodiment of the present invention shown preferably provides a vertical filter that is easy to disassemble during the cleaning process, including a cylinder 1, a filter basket 2 and a sealing cover 3; the cylinder 1 is respectively provided with a water inlet 4 and a water outlet 5, the filter basket 2 is arranged in the cylinder 1 and is located between the water inlet 4 and the water outlet 5, the upper end of the cylinder 1 has a disassembly hole 6, and the sealing cover 3 is threadedly connected to the disassembly hole 6; wherein, the filter basket 2 is connected to a blowing device 7 that can blow air into its inner cavity, the filter basket 2 and the sealing cover 3 are arranged on the same central axis, and a movable groove 8 is provided along the circumference of the lower side of the sealing cover 3, a connecting rod 9 is provided on the filter basket 2, the upper end of the connecting rod 9 is movably arranged in the movable groove 8, and a retaining ring 10 is provided in the cylinder 1 and on the filter basket 2, the filter basket 2 can pass through the connecting rod 9 so that it can move upward relative to the cylinder 1 with the sealing cover 3 and be accommodated in the inner side of the retaining ring 10.

[0021] Specifically, the sealing cover is threadedly connected to the cylinder body, and the user can install and remove the sealing cover by twisting the sealing cover. The connecting rod is connected to the movable groove on the lower side of the sealing cover, so that when the sealing cover is twisted, the filter basket will not rotate, but only drive the filter basket to move up and down with the sealing cover.

[0022] Therefore, when the sealing cover is removed and lifted, the filter basket can be lifted and removed synchronously through the connecting rod, thereby simplifying the user's disassembly and cleaning process, and the lifted filter basket is located on the inner side of the retaining ring, and the retaining ring can be used to block the filter holes on the side of the filter basket. At this time, the blowing device is combined to blow air to clean the inner cavity of the filter basket. After the filter holes on the side of the filter basket are blocked, the air flow can only be blown out through the upper opening of the filter basket, so that the filter waste in the filter basket can be brought out by the air flow, so that the filter basket is easy to clean.

[0023] Furthermore, the inner diameter of the retaining ring 10 is equal to the outer diameter of the filter basket 2. The retaining ring can seal the filter holes around the filter basket, effectively preventing the filter waste from falling into the cylinder due to the gap between the retaining ring and the filter basket when the blowing device blows air into the inner cavity of the filter basket.

[0024] Furthermore, the blowing device 7 includes an air pump 71 and a flexible air pipe 72. The air pump 71 is disposed below the cylinder 1. A first air inlet pipe 73 is disposed at the lower end of the cylinder 1. The first air inlet pipe 73 is provided with a first on-off valve (not shown). A second air inlet pipe 74 is disposed at the lower end of the filter basket 2. The second air inlet pipe 74 is provided with a one-way valve (not shown). The air outlet of the air pump 71 is connected to the first air inlet pipe 73, and the flexible air pipe 72 is connected between the first and second air inlet pipes 73 and 74. Specifically, the one-way valve allows fluid or gas to flow only toward the inner cavity of the filter basket. When the air pump is operating, it blows air into the inner cavity of the filter basket through the first, flexible, and second air inlet pipes in sequence to assist in cleaning. The first on-off valve enables the first air inlet pipe to be opened and closed, facilitating user convenience and effectively improving safety.

[0025] Furthermore, a sewage pipe 11 is provided on one side of the lower part of the cylinder 1, and a second switch valve (not shown) is provided on the sewage pipe 11. Specifically, the sewage in the cylinder is discharged through the sewage pipe, and the second switch valve is convenient for users to use.

[0026] Furthermore, the upper end of the cylinder 1 is detachably fixedly connected to a cover plate 12 by bolts, and the disassembly hole 6 and the retaining ring 10 are respectively formed on the cover plate 12.

[0027] Furthermore, a first sealing ring (not shown) is provided at the connection between the cover plate 12 and the cylinder body 1, thereby effectively enhancing the sealing performance.

[0028] Furthermore, a second sealing ring (not shown) is provided at the connection between the cover plate 12 and the sealing cover 3, thereby effectively enhancing the sealing performance.

[0029] Furthermore, a lifting ring 13 is provided on the upper side of the sealing cover 3. The sealing cover can be lifted and fixed by the lifting ring after being disassembled, thereby facilitating the maintenance of the filter basket being located in a clean state inside the retaining ring.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
