[0022] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, it should be understood that the orientation or positional relationships indicated by terms such as "front", "rear", "upper", "lower", "left", "right", "longitudinal", "transverse", "vertical", "horizontal", "top", "bottom", "inner", "outer", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings and are constructed and operated in a specific orientation, and are only for the convenience of describing the present technical solution, rather than indicating that the indicated devices or elements must have a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0023] It should also be noted that, unless otherwise clearly defined and limited, terms such as "install", "connect", "join", "fix", "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located above the other element, or there may also be one or more intermediate elements. Terms such as "first", "second", "third", etc. are only for the convenience of describing the present technical solution and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second", "third", etc. may explicitly or implicitly include one or more of such features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are presented to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0025] Referring to Figures 1 to 4 , a water purifier 100 provided by an embodiment of the present invention includes: a filter element 200 and a base 300 detachably connected to the filter element 200; the base 300 includes a locking member 310 and an unlocking member 320, and the locking member 310 is configured to lock or unlock the filter element 00 after the filter element 200 is pressed.

[0026] In this way, by setting the locking member 310, the filter element 200 can be locked, and the unlocking member 320 can cooperate with the locking member 310 to remove the filter element 200, simplifying the operation steps of installing and removing the filter element 200 and improving the user experience.

[0027] The number of the unlocking member 320 and the locking member 310 is at least two, and the locking members 310 and the unlocking members 320 are arranged in one-to-one correspondence. The unlocking member 320 is adjacent to the locking member 310, and the unlocking member 320 is arranged above the locking member 310 and is used for movably clamping with the locking member 310. In a specific application, the two locking members 310 are symmetrically arranged with respect to the center line of the filter element 100. That is, the locking member 310 and the unlocking member 320 are arranged on the opposite sides of the filter element 100. In this way, the fixing of the filter element 200 can be better realized, the filter element 200 is not easy to shake, and the stability is better.

[0028] The locking member 310 includes a plug pin 311 and a first elastic member 312 abutted against the plug pin 311, and the plug pin 311 is movably clamped with the filter element 100. The unlocking member 320 includes a limiting groove 321, a limiting rod 322 slidably arranged in the limiting groove 321, and a second elastic member 323 sleeved on the circumferential side of the limiting rod 322. The limiting rod 322 is arranged above the plug pin 311 and can compress the plug pin 311 so that the plug pin 311 compresses the first elastic member 312.

[0029] In practical applications, both the first elastic member 312 and the second elastic member 323 can be springs or other elastic components, as long as they can make the plug pin 311 and the limiting rod 322 pop out or reset.

[0030] The filter element 200 includes a retaining ring 210, and the retaining ring 210 is movably clamped with the plug pin 311. The filter element 200 further includes a second attracting member 220, the second attracting member 220 is arranged close to the retaining ring 210, and the second attracting member 220 is magnetically connected to the first attracting member 324. Both the first attracting member 324 and the second attracting member 220 can be magnets. In a specific application, the first attracting member 324 can also be set as a magnet and the second attracting member 220 as an iron block. Of course, the first attracting member 324 can also be set as an iron block and the second attracting member 220 as a magnet. The first attracting member 324 and the second attracting member 220 can also be set as other magnetic components. In practical applications, when the second attracting member 220 is pulled out of the base 300 along with the filter element 200, the first attracting member 324 can be adsorbed so that the first attracting member 324 is separated from the plug pin 311.

[0031] The base 300 can be set as a plastic base. The plastic base is light in weight, facilitating installation and handling. Preferably, the base 300 can adopt a water circuit board, and the sealing performance between the filter element 200 and the water circuit board is strong, reducing the risk of water leakage. Of course, the filter element 200 can also be set to include a plastic housing. Setting the housing of the filter element 200 as a plastic housing can reduce the weight of the entire water purifier 100.

[0032] Specifically, the steps of assembling the filter element 200 to the base 300 include: pressing the filter element 200 to make the filter element 200 move downward, the locking member 310 in the filter element disassembly and assembly structure 100 retracts, the filter element 200 continues to move downward, and the locking member 310 locks the filter element 200 to complete the installation of the filter element 200.

[0033] The steps of disassembling the filter element 200 from the base 300 include: pressing the filter element 200 to make the filter element 200 press downward, the locking member 310 retracts, the unlocking member 320 in the filter element disassembly and assembly structure 100 blocks the locking member 310, pulling the filter element 200 upward, and the unlocking member 320 disengages from the locking member 310.

[0034] It can be understood that the above embodiments only represent the preferred embodiments of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention shall fall within the scope covered by the claims of the present invention.
