[0002] As times progress, people have higher and higher requirements for their daily living standards. Drinking water is an important part of people's daily lives, but it may contain a certain amount of impurities, so it needs to be purified and filtered to meet people's actual needs. Therefore, filters are needed to purify and filter the water.

[0003] During the water purification and filtration process, filter elements may be damaged due to prolonged use, thus requiring maintenance. However, traditional filters are not easy to disassemble and assemble, and it is difficult to easily replace and maintain the filter elements, which limits their use. Utility Model Content

[0004] The purpose of this invention is to provide a filter with a replaceable filter element to solve the shortcomings of existing filters that are inconvenient to disassemble, install, and maintain.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a filter with replaceable filter element, comprising a filter body and a cover;

[0006] The filter body is provided with a cover at the top, and the top of the cover is provided with a water inlet. Limiting structures are evenly provided at the top of the filter body.

The limiting groove is evenly provided with the top of the filter element body. A filter element body is provided inside the filter element body on one side of the limiting groove. A fixing block is evenly fixed on the outer wall of the top of the filter element body. Reserved grooves are provided inside the filter elements on both sides of the limiting groove. A limiting plate is provided inside the reserved groove. A limiting spring is fixed on one side of the limiting plate, and a pull rod is fixed to the top of the limiting plate.

[0010] Preferably, the limiting grooves are evenly distributed at the top of the filter body, and the fixing blocks are evenly distributed at the outer wall of the top of the filter body.

[0011] Preferably, the top of the pull rod extends to the outside of the filter body, and the side of the limiting spring away from the limiting plate is fixedly connected to the side inside the reserved groove.

[0012] Preferably, the top end of the fixing block abuts against the bottom end of the limiting plate, and the fixing block and the limiting groove form a locking structure through the limiting plate.

[0013] Preferably, the disassembly and assembly structure includes protrusions, snap-fit ​​grooves, rotating grooves, internal grooves, snap-fit ​​rods, and return springs. The protrusions are evenly fixed to the bottom end of the water inlet. Snap-fit ​​grooves are provided on one side of each protrusion. The rotating grooves are evenly provided at the top of the filter body. Internal grooves are provided inside the filter body outside the rotating grooves. Snap-fit ​​rods are provided inside the internal grooves. Return springs are provided inside the internal grooves on the outer wall of the snap-fit ​​rods.

[0014] Preferably, the protrusions are evenly distributed at the top of the filter body, and all the protrusions are disposed inside the rotating groove. The water inlet and the rotating groove form an engaging structure through the protrusions.

[0015] Preferably, one side of the snap-fit ​​rod extends to the outside of the filter body, and the other side of the snap-fit ​​rod is disposed inside the snap-fit ​​groove. The snap-fit ​​rod and the protrusion form an engaging structure through the snap-fit ​​groove.

[0016] The filter with replaceable filter element provided by this utility model has the following advantages:

[0017] By setting a limiting structure, when installing the filter element body, the fixing block is squeezed into the limiting groove, and during the squeezing process, the limiting plate moves into the reserved groove. When the filter element body moves under the limiting plate, it is simultaneously restored by the elastic force of the limiting spring, so that the fixing block is not easy to fall out of the limiting groove. During the removal process, the limiting plate is moved into the reserved groove by pulling the pull rod, thereby releasing the positioning. This achieves the purpose of facilitating the disassembly and maintenance of the filter element.

[0018] By incorporating a disassembly and assembly structure, the device allows the bottom protrusion to be positioned within the rotating groove during installation, thus limiting the cover's movement. To prevent loosening during use, the protrusion, during rotation, presses the locking rod into the internal groove. When the locking groove moves to one side of the locking rod, a return spring pushes the locking rod into the groove for positioning. During disassembly and assembly, pulling the locking rod releases the positioning, facilitating easy disassembly and assembly of the cover for cleaning the interior of the filter body.
