Description

Technical Field

[0001] The utility model relates to the field of water purifier design, in particular to a quick-disassembly structure applied to a filter element of a water purifier. Background Art

[0002] A water purifier is a device used to purify drinking water, filtering the drinking water that flows through the water purifier. The water purifier includes a body and a water purifier filter element, wherein the water purifier filter element is the core part used to purify drinking water. In the prior art, the water purifier filter element includes a shell, one end of the shell is provided with an opening, the other end of the shell is provided with a water inlet and a water outlet, an end cover connected to the shell, and the end cover is disassembled by rotating with the shell through a locking structure, a filter element body is installed in the shell, and the end cover seals the filter element body in the shell. In specific applications, tap water enters the shell after passing through the water inlet, and then flows out from the water outlet after being filtered by the filter element body. After a certain period of use, dirt will adhere to the filter element body, and the filter element body needs to be replaced.

[0003] In this type of water purifier filter structure, a locking structure is used to allow the end cap and the housing to be disassembled and assembled by rotating them relative to each other at a certain angle. The water purifier filter element and the body are also assembled together using a similar locking structure. It is understandable that with this assembly structure, when the water purifier filter element is removed from the body, since the water purifier filter element is inserted into the body and only the end cap is exposed for application of rotational torque, when a rotational torque is applied to the end cap, it is very easy to remove the end cap from the body while the housing remains connected to the body, resulting in accidental disassembly and difficulty in disassembly.

[0004] To address the above-mentioned issues, the prior art (Announcement No.: CN216963752U, Announcement Date: 2022.07.15) discloses a water purifier filter cartridge that is easy to disassemble and assemble. This cartridge incorporates a rigid connection structure that allows the end cap to stably transmit rotational torque to the housing. During the process of removing the water purifier filter cartridge from the body, after applying rotational torque to the end cap, this torque can be stably transmitted to the housing, preventing the end cap and the housing from rotating relative to each other and causing the end cap to be removed from the housing, thereby effectively preventing accidental removal. After the water purifier filter cartridge is removed from the body, the rigid connection between the end cap and the housing is released, and the end cap can be removed from the housing to replace the filter cartridge.

[0005] In the above scheme, since the tail end of the inner cavity is installed in the body of the purifier by twisting, and the end cover is also installed on the inner cavity by twisting, it is necessary to provide a rigid connection structure on the end cover. This installation method requires a handle to be provided on the end cover. The semicircular edge for fixing the latch cannot be used as a handle, resulting in a large end cover. In addition, the connection of the end cover only has locking blocks on both sides. When cooperating with the socket in the opening, due to the heavy weight of the filter element, especially when it is filled with water, the connection is easily unstable and cannot be fastened through the snap-fit ​​mechanism on both sides alone. As a result, when the filter element is disassembled, the end cover is at risk of falling off by itself. When the end cover falls off, the filter element will fall with it, posing a safety hazard. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0007] A quick-release structure for a water purifier filter element, comprising a water purifier and a filter element housing, wherein an end cap is detachably mounted on one end of the filter element housing, a filter element is gap-fittedly mounted in the filter element housing, the end cap seals the filter element in the filter element housing, and the filter element housing is detachably mounted in the water purifier;

[0008] The inner side of the end of the filter element housing is formed with four groups of snap-fitting convex edges, which are arranged in a circular array and separated from each other. One end of the end cover is inserted into the filter element housing through a gap, and the outer side of the end cover inserted into the filter element housing is formed with four groups of snap-fitting edges. The four groups of snap-fitting edges are inserted into the filter element housing through the separation gaps of the four groups of snap-fitting convex edges in a one-to-one manner, and the snap-fitting edges are twisted and snapped onto the snap-fitting convex edges in a one-to-one manner.

[0009] Two sliding locks are slidably mounted on the end surface of the end cover, an outer cover is fixedly mounted on the end cover, a screw is rotatably mounted inside the outer cover, and the screw drives the two sliding locks to extend or retract.

[0010] Furthermore: a filter element assembly groove is formed on the water purifier, and the filter element shell can be detachably installed in the filter element assembly groove.

[0011] Furthermore: lock grooves are formed on both sides of the end of the filter element assembly groove, and when the sliding lock is extended, it is inserted into the lock groove with clearance fit.

[0012] Furthermore: a semicircular arc handle is rotatably mounted on the outer cover, and both ends of the screw are respectively fixedly mounted on the two ends of the semicircular arc handle.

[0013] Further: a single group of said snap-fitting convex edges is provided with at least three, at least three snap-fitting convex edges are parallel to each other and are spaced apart at equal distances, a single group of said snap-fitting edges is provided with at least three, and when the snap-fitting edges are twisted together, they abut against the inner side walls of the snap-fitting convex edges one by one.

[0014] Further: a first semicircular anti-retreat edge is formed on one or more of the snap-fit ​​convex edges, and one or more second semicircular anti-retreat edges are formed on the outer side of one end of the end cover inserted into the filter element housing. The second semicircular anti-retreat edges and the snap-fit ​​edges are staggered with each other, and the first semicircular anti-retreat edge is twisted and snap-fitted with the second semicircular anti-retreat edge.

[0015] Furthermore: a weight-reducing groove is formed on the outer side of the buckle edge, and a plurality of supporting ribs are integrally formed in the weight-reducing groove, and the plurality of supporting ribs are spaced apart from each other.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. After the end cap is screwed together, the entire filter housing can be installed into the water purifier. By turning the screw, the two sliding locks are extended and locked with the water purifier. It is convenient and quick. When disassembling, first turn the screw in the opposite direction. At this time, the two sliding locks will retract and no longer jam the water purifier. At this time, the filter housing can be pulled out through the end cap, which is convenient for actual operation.

[0018] 2. When the entire filter element housing is lifted by the end cover, the end cover is connected to the snap-on convex edge inside the filter element housing through four sets of snap-on edges that are twisted and snapped one by one. Therefore, the connection between the end cover and the filter element housing is very stable and will not be loose or not tightly fastened, thereby reducing the risk of the filter element housing falling alone.

[0019] The utility model can facilitate the disassembly of the end cover, and further facilitates the removal of the filter element in the filter element housing for replacement or cleaning.
