[0134] like Fig.16 , 17 As shown in FIG. 20 , the filter element 1 of this embodiment includes a filter element housing 11 and a filter element body 12 , and the filter element body 12 is located inside the filter element housing 11 .

[0135] The filter element housing 11 is generally cylindrical, and includes a side wall 111 and ends located at both ends of the side wall 111 . The filter element housing 11 forms a space for accommodating the filter element body 12 .

[0136] A raw water space is formed between the outer wall surface of the filter element body 12 and the side wall 111 of the filter element housing 11 , which is connected to the filter element water inlet 551 , and the central hole of the filter element body 12 is connected to the filter element water outlet 552 .

[0137] One end of the filter element housing 11 is a closed end 112 , and the other end is an open end. The filter element housing 11 includes a filter element cover 13 , and the open end is assembled with the filter element cover 13 .

[0138] Generally, the filter element 1 has a certain lifespan. In order to facilitate the installation and removal of the filter element 1, the present embodiment improves the structure of the filter element housing 11. A clamping member 2 is provided on the filter element housing 11, and a second clamping structure 31 that cooperates with the clamping member 2 is provided on the water supply device housing 51. The assembly is convenient and quick through the clamping member 2 and the second clamping structure 31. When the clamping member 2 is clamped with the second clamping structure 31, the filter element 1 is connected to the filter element connector 54, the filter element water inlet 551 is connected to the filter element connector water inlet 541, and the filter element water outlet 552 is connected to the filter element connector water outlet 542.

[0139] A clamping member 2 is provided on the filter element housing 11, and the clamping member 2 includes a clamping portion 21. The clamping portion 21 has a first clamping structure 211. There is a certain gap between the clamping portion 21 and the side wall of the filter element housing 11. The clamping portion 21 can be offset and reset toward the side wall 111 of the filter element housing 11.

[0140] The clamping portion 21 is made of a material that has a certain hardness and can deform to a certain extent and can be restored after deformation.

[0141] The first clamping structure 211 of the present embodiment is configured as a clamping claw. Of course, the first clamping structure 211 can also be configured as a clamping block, a clamping slot, a clamping hole or other clamping forms.

[0142] Correspondingly, such as Fig.18 , 19 As shown, a second clamping structure 31 adapted to the first clamping structure 211 is provided on the water supply device housing 51. When the first clamping structure 211 and the second clamping structure 31 cooperate, a clamping fixation is formed.

[0143] When the first clamping structure 211 is configured as a clamping claw or a clamping block, the second clamping structure 31 is configured as a clamping slot or a clamping hole; when the first clamping structure 211 is configured as a clamping slot or a clamping hole, the second clamping structure 31 is configured as a clamping claw or a clamping block.

[0144] To facilitate the installation of the filter element, the extension direction of the clamping portion 21 is roughly the same as the extension direction of the side wall 111 of the filter element housing 11. Therefore, the clamping component 2 of this embodiment also includes a connecting portion 22, which is used to connect the filter element housing 11 and the clamping portion 21. The connecting portion 22 and the clamping portion 21 are set at a certain angle.

[0145] Preferably, the connection portion 22 is disposed at 90 degrees to the side wall 111 , and the connection portion 22 is disposed at 90 degrees to the clamping portion 21 .

[0146] The connection part 22 is made of a hard material, or the connection part 22 can also be made of a material that has a certain hardness and can be deformed to a certain extent and can be restored after deformation.

[0147] The connection portion 22 is disposed on the side wall 111 of the filter cartridge housing 11 near the closed end 112 of the filter cartridge housing 11. Preferably, the bottom of the connection portion 22 is flush with the end of the filter cartridge housing 11, which can reduce the contact stroke between the clamping member 2 and the filter cartridge assembly during the installation of the filter cartridge 1, facilitate installation, reduce installation force, and reduce the deformation time of the clamping member 2, thereby avoiding deformation and damage of the clamping member 2.

[0148] Since the clamping member 2 is added to the filter element housing 11, the volume of the filter element 1 is inevitably increased. In order to minimize the impact of the clamping member 2 on the volume of the filter element 1, a recess 113 for making way for the clamping member 2 is provided at a position corresponding to the clamping member 2 on the filter element housing 11. The connecting portion 22 is partially located in the recess 113. When the clamping portion 21 is deformed toward the side wall 111 of the filter element housing 11, the recess 113 can make way for the clamping portion 21.

[0149] When disassembling the filter element 1 , the first clamping structure of the clamping portion 21 can be directly removed from the second clamping structure of the filter element assembly by using a tool.

[0150] In order to facilitate the disassembly of the filter element 1, a force application area 212 is provided on the clamping portion 21. When a force is applied to the force application area 212, the clamping portion 21 is deformed toward the side wall 111 of the filter element housing 11, so that the clamping and fixing effect of the first clamping structure 211 and the filter element assembly disappears, and the filter element 1 can be disassembled. Of course, when the filter element 1 is installed, in order to avoid wear caused by the contact between the first clamping structure 211 and the filter element assembly and reduce the installation friction, a force can be applied to the force application area 212, so that the clamping portion 21 is deformed toward the side wall 111 of the filter element housing 11. When the installation is in place, the force is canceled, the clamping portion 21 is reset, and the first clamping structure 211 is clamped and fixed with the filter element assembly.

[0151] Preferably, the force application area 212 is located between the first clamping structure 211 and the connecting portion 22 .

[0152] In order to facilitate force application, a plurality of protrusions or grooves are provided on the force application area 212 to increase the roughness of the force application area 212, improve the success rate of force application, and avoid the situation where force application is difficult due to the smooth surface of the force application area 212.

[0153] Preferably, two clamping parts 2 are provided on the filter element 1, and the two clamping parts 2 are symmetrically arranged on both sides of the filter element 1. Therefore, when removing the filter element 1, it is only necessary to pinch the force application area 212 and pull out the filter element 1, which is very simple and convenient to operate.

[0154] In some other embodiments, the connecting portion 22 may also be provided on the filter element cover 13. In this case, according to the positional relationship between the clamping portion 21 and the filter element cover 13, the relief groove 113 may be completely located on the filter element cover 13, or completely located on the side wall 111 of the shell body, or partially located on the filter element cover 13 and partially located on the side wall 111 of the shell body.

[0155] The bottom of the water supply device housing 51 is open, and the filter element 1 is installed into the water supply device housing 51 through the bottom.

[0156] The water supply device housing 51 is provided with a second clamping structure 31 which cooperates with the first clamping structure 211 .

[0157] The filter element 1 is installed in the water supply device housing 51 , and a second clamping structure 31 is provided on the inner wall of the water supply device housing 51 .

[0158] In this embodiment, the first clamping structure 211 is a clamping claw, and the second clamping structure 31 is a clamping slot or a clamping hole.

[0159] Generally, after the filter element 1 is installed in the water supply housing 51 , the closed end 112 of the filter element 1 is flush with the bottom of the water supply housing 51 , and thus the second clamping structure 31 is located on the inner wall of the water supply housing 51 near the bottom.

[0160] Correspondingly, such as Fig.18 , 19 As shown, a notch groove 32 for exposing the force application area 212 is provided on the water supply device housing 51 .

[0161] Of course, the form of the notch groove 32 is not fixed, and it can also be a through hole set on the water supply device housing 51.

[0162] Therefore, the filter element and the water supply device housing are detachably connected, and only two actions are required to remove the filter element: pinching the card connector and pulling out the filter element, which is simple to operate.

[0163] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
