Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and specifically to a filter cartridge locking structure for a water purifier. Background Technology

[0002] A water purifier is a water purification device that deeply filters and purifies water according to usage requirements. It effectively filters out rust, sand, colloids, and adsorbs residual chlorine, odors, discoloration, pesticides, and other chemicals. It also effectively removes bacteria, germs, toxins, heavy metals, and other impurities from the water. It is widely used in both residential and commercial settings.

[0003] Water purifier filter cartridges need to be replaced after a period of use. Currently, water purifiers generally replace filter cartridges by rotating the filter cartridge body. Since the top cover and filter cartridge are connected by rotation in the filter cartridge body, the filter cartridge and top cover may become loose and fall off during disassembly. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a filter cartridge locking structure for a water purifier, comprising a filter cartridge body, a filter cartridge frame, and a fixing mechanism. The filter cartridge body is connected to the filter cartridge frame via the fixing mechanism. The fixing mechanism includes an annular rotating lock, which is rotatably mounted on the filter cartridge frame. The rotating lock has a locking clip. The filter cartridge body has a groove on its circumference, and the locking clip corresponds one-to-one with the groove. One end of the groove has a vertical opening, and the size of the opening is not smaller than the size of the locking clip. The filter cartridge body is inserted into the rotating lock, and the locking clip rotatably engages with the groove through the opening.

[0005] Furthermore, the rotary lock is also provided with a lever, which is installed on the top surface of the rotary lock and has a finger groove for placing a finger.

[0006] Furthermore, a front cover panel of the main unit is installed on the filter element frame. The front cover panel of the main unit is provided with a connecting groove for cooperating with the lever. The front cover panel of the main unit is located above the rotating buckle and is fixedly connected to the filter element frame by screws.

[0007] Furthermore, the front cover panel of the main unit is provided with a positioning post, and the filter element frame is provided with a positioning hole, and the positioning post and the positioning hole cooperate with each other.

[0008] Furthermore, both the locking clip and the groove are two in number, and the two locking clips or the grooves are symmetrically arranged between each other.

[0009] Furthermore, the opening is chamfered.

[0010] Furthermore, the locking clip is equipped with an elastic mechanism, through which the locking clip abuts against the side wall of the groove.

[0011] Furthermore, the elastic mechanism includes a spherical ball and a spring. The locking clip is provided with a mounting hole. The spherical ball is rotatably mounted in the mounting hole. One end of the spring is fixedly connected to the bottom of the mounting hole, and the other end abuts against the spherical ball.

During this process, the locking clip 4 will disengage from the groove 5 at the opening 51.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2As shown, the rotary lock 3 is also provided with a lever 6, which is installed on the top surface of the rotary lock 3, that is, on the side of the rotary lock 3 away from the filter element frame 2. The lever 6 has a finger groove for placing fingers. The lever 6 is detachable for easy installation. The filter element frame 2 is equipped with a main unit front cover panel 7. The main unit front cover panel 7 has a connecting groove 8 for cooperating with the lever 6. The number of connecting grooves 8 corresponds one-to-one with the number of filter element bodies 1. When there are multiple filter element bodies 1, the main unit front cover with the corresponding number of connecting grooves 8 can be selected according to the number of filter element bodies 1. Panel 7 allows multiple filter cartridge bodies 1 to be integrated and installed together via the front cover panel 7 of the main unit. The front cover panel 7 of the main unit is located above the rotating latch 3 and is fixedly connected to the filter cartridge frame 2 by screws. In actual use, the surface of the lever 6 does not protrude from the surface of the front cover panel 7 of the main unit, and preferably the two are flush, thereby improving the aesthetic effect. The front cover panel 7 of the main unit is provided with positioning posts, and the filter cartridge frame 2 is provided with positioning holes. The positioning posts and positioning holes cooperate with each other. Two positioning posts and positioning holes can be provided, and the two are ensured to be asymmetrical, thereby forming a foolproof setting.

[0030] In this embodiment, the toggle block 6 allows for convenient finger control of the rotating latch 3; the front cover panel 7 of the main unit prevents the rotating latch 3 from detaching from the filter element frame 2, while also improving the overall aesthetics; combined with the connecting groove 8, it restricts the direction and position of the toggle block 6. Specifically, when the filter element body 1 is in the locked state, the toggle block 6 is located at one end of the connecting groove 8; when the toggle block 6 is located at the other end of the connecting groove 8, the filter element body 1 is in the unlocked state; the positioning pin and positioning hole facilitate quick installation and positioning of the front cover panel 7 of the main unit, improving installation efficiency.
