A limiting ball groove is provided on the movable seat. The limiting ring is arranged inside the movable seat to limit the position of the filter element mounting cylinder. The filter element mounting cylinder is slidably installed inside the movable seat and corresponds to the position of the limiting ball groove. Filter elements are provided at both ends of the filter element mounting cylinder. The driving device drives the movable seat to slide through the transmission device.

[0009] Furthermore, the driving device includes a connecting tube, a push plug, a second spring and a connecting rod. The connecting tube is arranged on the machine body, the push plug slides inside the connecting tube, the second spring is arranged inside the connecting tube, and the push plug is connected to the transmission device through the connecting rod.

[0010] Further, the transmission device includes a first rack, a mounting seat plate, a gear, a first bevel gear, a second bevel gear, a pushing gear and a pushing rack, the first rack is arranged on the connecting rod, the mounting seat plate is arranged on the machine body, the gear, the first bevel gear, the second bevel gear and the pushing gear are arranged on the mounting seat plate, the gear is connected to the first bevel gear, the second bevel gear is connected to the pushing gear, the first bevel gear and the second bevel gear are meshed, the first rack is meshed with the gear, the pushing gear is meshed with the pushing rack, and the pushing rack is arranged on the moving seat.

[0011] The advantages of the present invention are:

[0012] The utility model processes the material inside the body, and the liquid will accumulate inside. The accumulated liquid will then be filtered through the filter device assembly inside the connecting nozzle at the bottom end of the body. Then, as the filtering time increases, the filter residue on the filter device assembly will continue to accumulate and affect the discharge of the liquid. When the liquid inside the body accumulates to a certain amount, the liquid inside the body will drive the driving device, and then the transmission device will drive the filter device assembly to slide and replace the filter element without filter residue.
