For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] At present, filter elements are basically designed to be replaceable, so that the service life of the water purifier can be extended by replacing the filter element when the filtering capacity of the filter element decays. The detachable design of the conventional filter element is to set the filter bottle cover of the filter element to be rotatable relative to the whole water purifier. When the filter element needs to be replaced, the filter element can be removed from the whole machine by rotating the filter bottle cover. However, since the filter element is under pressure when water passes through the filter element, the inside of the filter element will be under pressure, making it difficult to rotate the filter bottle cover relative to the whole machine, resulting in difficulty in disassembly and assembly.

[0041] To this end, the utility model proposes a fixing structure of the filter element and the whole machine, referring to Figure 1-3 As shown, the fixing structure 100 includes an operating part 11 and a locking member 12. The operating part 11 is connected to the filter element 200, and the operating part 11 can rotate relative to the filter element 200; the locking member 12 is connected to the operating part 11, and the locking member 12 is configured to be able to move between a first position and a second position; when the locking member 12 is in the first position, the locking member 12 is clamped and fixed to the entire machine housing 300; when the locking member 12 is in the second position, the locking member 12 is disengaged from the entire machine housing 300.

[0042] The operating part 11 is a component for a person to hold and rotate when the filter element 200 is disassembled or assembled. The operating part 11 is located outside the filter element. The locking member 12 can be driven to move by rotating the operating part 11.

[0043] The locking member 12 is a component for locking the filter element 200. When the locking member 12 is engaged with the whole machine housing 300, the filter element 200 is locked in the whole machine housing 300. When the locking member 12 is disengaged from the whole machine housing 300, the filter element 200 can be taken out of and loaded into the whole machine housing 300.

[0044] The clamping means that the locking member 12 is in contact with the entire housing 300 . The contact may be that the locking member 12 abuts against the entire housing 300 , the end of the locking member 12 is embedded in the entire housing 300 , or the locking member 12 passes through the entire housing 300 .

[0045] The first position is Figure 2 The second position refers to the position of the locking member 12, at which the locking member 12 is engaged with the entire housing 300. Figure 3 The locking member 12 is located in the middle position, and at this time, the locking member 12 is separated from the entire machine housing 300.

[0046] This embodiment provides an operating portion 11 that is independent of the filter element 200. The operating portion 11 is not under pressure when water flows through the filter element 200, so it is easy to rotate, thereby effectively solving the problem of difficult disassembly and assembly in the existing structure.

[0047] In the embodiments of the present invention, continue to refer to Figure 1-3 As shown, there are two groups of locking members 12 , and the two groups of locking members 12 can move closer to or farther from each other when the operating portion 11 rotates.

[0048] Specifically, refer to Figure 2 and 3 As shown, the two groups of locking members 12 are distributed at 180°. The locking members 12 approach each other means that the two groups of locking members 12 move inward when the operating part 11 rotates and disengage from the entire machine housing 300; the locking members 12 move away from each other means that the two groups of locking members 12 move outward when the operating part 11 rotates and engage with the entire machine housing 300.

[0049] The two sets of locking members 12 can enhance the locking strength between the filter element 200 and the entire housing 300. In addition, the two sets of locking members 12 can be driven to move simultaneously by one operating portion 11, thereby simplifying the structure and making the operation simple.

[0050] In the embodiment of the present utility model, the locking member 12 is slidably connected to the operating portion 11 , and the locking member 12 can move horizontally and linearly between the first position and the second position under the condition that the operating portion 11 rotates.

[0051] The sliding connection between the locking member 12 and the operating portion 11 means that the locking member 12 and the operating portion 11 are in contact with each other but not fixed, and at this time, the locking member 12 does not rotate synchronously with the rotation of the operating portion 11. Horizontal linear movement means that the first position and the second position are on the same horizontal line, there is no height difference between the first position and the second position, and the locking member 12 moves along the straight line between the first position and the second position.

[0052] The horizontal linear movement of the locking member 12 is achieved by means of a sliding connection, and the structure is simple and reliable.

[0053] In the embodiments of the present invention, reference is made to Figure 2-6 As shown, the operating portion 11 is provided with an arc groove 111, and the locking member 12 is provided with a boss 121, and the boss 121 is slidably connected with the arc groove 111; the arc groove 111 has a first end 1111 and a second end 1112, Figure 4 As shown, when the locking member 12 is in the first position, the first end 1111 of the arc groove 111 abuts against the protrusion 121 (the first end 1111 is blocked by the locking member 12). Figure 5 As shown, when the locking member 12 is in the second position, the second end 1112 of the arc groove 111 abuts against the boss 121 (the second end 1112 is blocked by the locking member 12 ); along the radial direction of the operating portion 11 , the first end 1111 is located outside the second end 1112 .

[0054] Specifically, refer to Figure 4-6 As shown, the main body of the operating portion 11 may be cylindrical, but its shape may be adjusted according to actual needs. The arc groove 111 is provided on the lower surface of the operating portion 11. In other embodiments, the arc groove 111 may also be provided through the operating portion 11. Figure 2-5 As shown, the locking member 12 is located below the operating portion 11, and the locking member 12 is a rectangular block structure. In other embodiments, the locking member 12 can also be set to a cylindrical shape. Figure 7 As shown, the boss 121 is arranged on the upper surface of the locking member 12. In order to ensure smooth cooperation with the arc groove 111, the boss 121 is cylindrical. In other embodiments, the boss 121 can also be a sphere. The setting position of the boss 121 on the locking member 12 meets the following requirements: when the second end 1112 of the arc groove 111 abuts against the boss 121, there is a gap between the outer end of the locking member 12 and the entire machine housing 300.

[0055] Along the radial direction of the operating part 11, the first end 1111 is located on the outside of the second end 1112, which means that the arc groove 111 and the operating part 11 are not concentrically arranged, and the distance between the first end 1111 and the center of the operating part 11 is greater than the distance between the second end 1112 and the center of the operating part 11. In this way, when the operating part 11 rotates, the locking member 12 will be pushed to move in the radial direction of the operating part 11.

[0056] It should be noted that the reference Figure 4-6 As shown, when there are two groups of locking members 12, two corresponding groups of arc grooves 111 are provided on the operating portion 11, and the two groups of arc grooves 111 are rotationally symmetrically distributed, that is, one group of arc grooves 111 can overlap with another arc groove 111 after rotating 180°, so that when the operating portion 11 rotates, the two groups of locking members 12 approach or move away from each other.

[0057] In the embodiments of the present invention, reference is made to Figure 8 As shown, the locking member 12 is accommodated in a limiting groove 21 provided on the filter element 200 , and the locking member 12 can move horizontally along the limiting groove 21 when the operating portion 11 rotates.

[0058] Specifically, refer to Figure 8 As shown, the limiting groove 21 is provided at the top of the filter element 200, and the limiting groove 21 is distributed along the radial direction of the filter element 200, and extends from the center of the filter element 200 to the outer wall of the filter element 200, and the limiting groove 21 has a shape and size matching the locking member 12. Since the locking member 12 is limited in the limiting groove 21, when the operating portion 11 rotates, the locking member 12 can only move along the limiting groove 21, and when the locking member 12 moves outwardly along the limiting groove 21 to the first position, the locking member 12 is clamped and fixed with the whole machine housing 300; when the locking member 12 moves inwardly along the limiting groove 21 to the second position, the locking member 12 is separated from the whole machine housing 300.

[0059] The movement of the locking member 12 can be achieved on the basis of a simplified structure through the cooperation of the arc groove 111 , the protruding column 121 and the limiting groove 21 .

[0060] In the embodiments of the present invention, reference is made to Figure 2 and 3 As shown, the locking member 12 has an insertion end 122. When the locking member 12 is in the first position, the insertion end 122 of the locking member 12 is located in the lock hole 31 opened on the whole machine housing 300; when the locking member 12 is in the second position, the insertion end 122 of the locking member 12 exits the lock hole 31.

[0061] Specifically, refer to Figure 1-3 As shown, a locking hole 31 is provided on the whole housing 300 , and the position of the locking hole 31 corresponds to the position of the locking member 12 . In other embodiments, the locking hole 31 may also be a blind hole provided on the inner wall of the whole housing 300 .

[0062] The lock hole 31 cooperates with the locking member 12 , which is more reliable than a direct abutment fixation method.

[0063] In the embodiments of the present invention, reference is made to Figure 7As shown, the insertion end 122 of the locking member 12 is provided with a wedge surface 1221. The wedge surface 1221 is an inclined surface arranged on the lower surface of the locking member 12, which facilitates the insertion end 122 of the locking member 12 to enter and exit the lock hole 31.

[0064] In the embodiments of the present invention, reference is made to Figure 2 and 3 As shown, the operating portion 11 is rotatably matched with the first protrusion 22 provided on the filter element 200 .

[0065] Specifically, refer to Figure 2 and 3 As shown, the center of the operating portion 11 protrudes upward to form a second protrusion 112, that is, the second protrusion 112 has a cavity, the first protrusion 22 is arranged at the center of the top of the filter element 200, the first protrusion 22 extends upward into the cavity of the second protrusion 112 and abuts against the second protrusion 112, and a pin 113 is passed through the junction between the second protrusion 112 and the top of the first protrusion 22, that is, the operating portion 11 is rotatably matched with the first protrusion 22 through the second protrusion 112 and the pin 113, thereby realizing the rotation of the operating portion 1 relative to the filter element 200.

[0066] In other embodiments, the operating portion 11 may also be directly sleeved on the first protruding portion 22 , and a bearing is embedded between the operating portion 11 and the first protruding portion 22 . In this case, the first protruding portion 22 is equivalent to a rotating shaft.

[0067] It should be noted that when there are two sets of locking members 12, the two sets of locking members 12 are respectively arranged on both sides of the first protrusion 22. In order to match the cylindrical first protrusion 22, refer to Figure 7 As shown, an escape groove 123 is also recessed at the inner end of the locking member 12 .

[0068] The provision of the first protrusion 22 can facilitate the rotational connection of the operating part 11 .

[0069] In the embodiments of the present invention, reference is made to Figure 1 and 9 As shown, a handle 114 is provided on the operating portion 11 .
