DETAILED DESCRIPTION

[0024] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0025] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the new buckle device for water filter cartridge of the present embodiment includes a filter cartridge body 1 for installation on a water purifier. The filter cartridge body 1 is internally provided with high-efficiency filtering materials such as activated carbon, ultrafiltration membrane or reverse osmosis membrane, etc. for removing impurities, peculiar smell, heavy metals and harmful substances in water, and ensuring the purity and safety of output water quality. The outer shape of the filter cartridge body 1 is designed to facilitate matching with the interface inside the water purifier, realizing seamless docking.

[0026] The top of the filter cartridge body 1 is provided with a mounting seat 2, which plays a supporting and positioning role. The mounting seat 2 is provided with a fixed pressing plate 3, which helps to fix the filter cartridge body 1 through physical pressure, preventing the filter cartridge from loosening during use. The fixed pressing plate 3 is hingedly provided with a pull ring 4, which provides an intuitive and easy-to-operate interface for replacing the filter cartridge. A locking mechanism 5 is provided between the fixed pressing plate 3 and the mounting seat 2, and the bottom of the pull ring 4 abuts against the locking mechanism 5. When the pull ring 4 is pulled, the locking mechanism 5 will responsively unlock, allowing the filter cartridge body 1 to be easily taken out or installed. When replacing the filter cartridge, the user only needs to gently pull the pull ring 4, and the locking mechanism 5 will be unlocked, at which time the filter cartridge body 1 can be easily taken out of the water purifier. When installing a new filter cartridge, align the filter cartridge body 1 with the water purifier interface, then press down until the filter cartridge body 1 completely fits the water purifier interface, and then release the pull ring 4, the locking mechanism 5 is automatically locked, completing the installation process. The steps of replacing the filter cartridge are simplified, and the efficiency is improved.

[0027] In combination with Figure 1 , Figure 4 , Figure 5 and Figure 6 , the locking mechanism 5 includes a guide seat 51 provided on the mounting seat 2, which provides stable support and guidance for other components. The two sides of the guide seat 51 are symmetrically provided with fixed buckles 52, and when the locking mechanism 5 is in the locked state, the hook part or the pawl part of the fixed buckle 52 tightly clamps the corresponding structure of the water purifier interface, preventing the filter cartridge from accidentally falling off.

[0028] The guiding seat 51 is connected with the fixed buckle 52 through a pull rod 53. One end of the pull rod 53 is connected with the fixed buckle 52, and the other end is connected with the inside of the guiding seat 51. When the pull ring 4 is pulled, the pull rod 53 will respondively move, drive the fixed buckle 52 to change from the state of stretching to the inside to shrink, the fixed buckle 52 is buckled, so as to realize the unlocking of the locking mechanism 5. One end of the guiding seat 51 is provided with a spring member 54. When the locking mechanism 5 is in the locked state, the spring member 54 is in the initial compression state, and the fixed buckle 52 locks the water purifier interface. Prevent the filter core body 1 from falling off, when the pull ring 4 is pulled, the spring member 54 will be further compressed, at the same time, the guiding seat 51 pulls the fixed buckle 52 to separate from the water purifier interface, so as to realize the unlocking of the filter core body 1.

[0029] One end of the pull ring 4 is provided with a circular ring 41, which is the main part for the user to hold and pull the pull ring 4. The other end of the pull ring 4 is hinged with the fixed pressing plate 3 and provided with a push plate 42 at the bottom, so that the pull ring 4 can flexibly rotate around the fixed point. The top end of the push plate 42 abuts against the end of the guiding seat 51. When the pull ring 4 is pulled, the push plate 42 will push the guiding seat 51 to move, and then drive the pull rod 53 and the fixed buckle 52 to act, so as to realize the unlocking of the locking mechanism 5. The surface of the push plate 42 can also be provided with anti-skid or guiding structure to ensure that it can move stably and smoothly during pushing.

[0030] In combination Figure 6 As shown, the fixed buckle 52 is provided with a sliding column 521, which can keep stable guidance and smooth mobility during sliding. One end of the sliding column 521 is firmly connected with the main part of the fixed buckle 52, and the other end penetrates one end of the pull rod 53 and matches with the first sliding groove 31 on the fixed pressing plate 3. The fixed pressing plate 3 is provided with the first sliding groove 31 matched with the sliding column 521, which ensures that the sliding column 521 can move stably and smoothly in the first sliding groove 31. The first sliding groove 31 can not only accommodate the moving range of the sliding column 521, but also prevent it from moving excessively or falling off. The sliding column 521 penetrates one end of the pull rod 53 and is slidably connected with the first sliding groove 31. So that the fixed buckle 52 can move along the direction of the first sliding groove 31 under the driving of the pull rod 53. When the pull ring 4 is pulled, the pull rod 53 will respondively move, and then drive the sliding column 521 on the fixed buckle 52 to slide in the first sliding groove 31. Not only the unlocking and locking functions of the locking mechanism 5 are realized, but also the stability and accuracy of the fixed buckle 52 during movement are ensured.

[0031] A guide post 511 is provided on the guide seat 51, which maintains stable guidance and smooth movement during sliding. One end of the guide post 511 is firmly connected to the main body of the guide seat 51, and the other end passes through the other end of the pull rod 53 and matches the second sliding groove 32 on the fixed pressure plate 3. The fixed pressure plate 3 is provided with a second sliding groove 32 that matches the guide post 511, ensuring that the guide post 511 can move stably and smoothly within it. The second sliding groove 32 can accommodate the range of movement of the guide post 511 while preventing it from moving excessively or falling off. The other end of the guide post 511, passing through the pull rod 53, is slidably connected to the second sliding groove 32. This allows the guide seat 51 to move along the direction of the second sliding groove 32 under the action of the pull rod 53. When the pull ring 4 is pulled, the pull rod 53 moves responsively, thereby causing the guide post 511 on the guide seat 51 to slide in the second sliding groove 32. This not only enables the locking and unlocking functions of the locking mechanism, but also ensures the stability and accuracy of the guide seat 51 during movement. Furthermore, the second sliding groove 32 is perpendicular to the first sliding groove 31.

[0032] The top two sides of the filter cartridge body 1 are provided with openings 6 for the fixing buckles 52 to pass through. This not only reflects a deep consideration for the convenience of filter cartridge replacement, but also ensures the stable installation of the filter cartridge in the water purification equipment.

[0033] Combination Figure 1 , Figure 2 and Figure 3 As shown, a placement groove 7 matching the pull ring 4 is provided at the center of the top of the filter element body 1. This not only optimizes the filter element replacement process but also improves the user experience. The shape of the placement groove 7 closely matches the shape of the pull ring 4 to ensure that the pull ring 4 can be securely embedded therein.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
