The utility model provides a filter element device and a water purifier comprising the same, the filter element device comprises a turntable, a filter element body, a first elastic piece and a second elastic piece, the turntable is sleeved on the filter element body, and one of the turntable and the filter element body is provided with a containing groove with an opening; in the first state, the abutting piece compresses the first elastic piece in the moving direction of the rotating disc. The second channel extends into the first channel to compress the second elastic piece, and the first channel is communicated with the second channel, so that water flows into the filter element body from the turntable; in the second state, under the action of the elastic force of the first elastic piece, the rotating disc rotates relative to the filter element body, the filter element body is separated from the rotating disc, and under the action of the elastic force of the second elastic piece, the second channel is separated from the first channel. In the first state, the first channel is communicated with the second channel, so that water can smoothly flow into the filter element body from the turntable; in the second state, the disc rotates relative to the filter element body, so that the filter element is convenient to mount and replace.

This utility model relates to the field of environmental protection technology and discloses a feeding mechanism for a double-effect evaporator used for treating yellow water at the bottom of a wine cellar. The mechanism includes an evaporator body with a support shaft fixedly connected to its upper surface. The evaporator filters the yellow water through a filter screen fixedly connected to the inner wall of the feeding box. When the drive motor rotates the lead screw, the lead screw drives the movable sleeve to move along the limiting groove and the transverse groove. The sliding scraper on the movable sleeve cleans the filter screen, effectively removing impurities from its surface and preventing accumulation. This ensures the filter screen's continuous and effective filtration function, ensuring a smooth feeding process from the feeding box to the evaporator body and avoiding problems such as feeding blockage caused by excessive impurities on the filter screen. A guide plate inside the feeding box directs impurities to a dust removal groove on the surface of the collection box, eliminating the need for manual cleaning and reducing workload.

The utility model relates to the technical field of water treatment filtration, and discloses a water treatment front multi-media filter which comprises a filter shell, a filter element is arranged in an inner cavity of the filter shell, a pushing assembly is arranged on the front face of the filter shell, and the pushing assembly comprises a pushing box. The normal filtering function of the filter is guaranteed by arranging the filter element and the filter shell, the position of the filter element can be adjusted by arranging the pushing assembly, the stepping motor is controlled to rotate forwards to drive the filter element to be separated from the filter shell, and the stepping motor is controlled to rotate backwards to drive the filter element to be inserted into the filter shell, so that the filter element is convenient to replace; by arranging the connecting assembly, the positioning insertion rod can be separated from the connecting block by pulling the pull head, the filter element is convenient to disassemble, the pull head is loosened, the positioning insertion rod can be driven to be inserted into the connecting block by utilizing resilience force of the positioning spring, and therefore the filter element is easy to install and operate and convenient to replace.
