[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] See also Figure 1 and Figure 6 The utility model provides a filter element locking structure, which includes a filter element 1, a body 2 and a handle 3. The body 2 is provided with an installation cavity 21 adapted to the filter element 1. The handle 3 is rotatably installed on the top of the filter element 1. The handle 3 is provided with a limiting portion 31. The center of gravity offset of the limiting portion 31 has a tendency to drive the handle 3 to rotate toward the body 2 and be flushly received on the top of the filter element 1, so as to lock the handle 3 in the installed state.

[0033] Therefore, the utility model provides a limit portion 31 on the handle 3, and the center of gravity of the limit portion 31 is offset, so that when the filter element 1 is installed in the installation cavity 21, the handle 3 can rotate to a horizontal state by its own weight to lock on the top of the filter element 1, thereby preventing the handle 3 from swinging or rotating, and ensuring that the filter element 1 is stably installed in the water purifier. In addition, the locking structure of the handle 3 is simple, easy to operate, and can effectively reduce costs.

[0034] Specifically, the filter element 1 includes a cylindrical filter element body 13 and an end cover 14, the end cover 14 is arranged on the top of the filter element body 13, and the handle 3 is rotatably mounted on the end cover 14. When the filter element 1 is installed in the installation cavity 21 of the body 2, the handle 3 is located above the installation cavity 21, so that the handle 3 can be rotated upward to lift it when it is disassembled. In the lifted state, the handle 3 is vertically arranged, and the handle 3 is an arc-shaped structure with a smooth surface, which is convenient for lifting. When the filter element 1 is installed in the installation cavity 21 of the body 2, the handle 3 rotates to a horizontal state due to the center of gravity offset of the limiting part 31 to be accommodated on the top of the end cover 14 and located above the installation cavity 21, so that when the filter element 1 needs to be removed, it is convenient to lift the handle 3 upward to lift the filter element 1 out of the installation cavity 21.

[0035] In the present invention, in the locked state, the handle 3 rotates toward the body 2 to a horizontal state, that is, after the filter element 2 is installed and before the installation cavity 21 is closed, the handle 3 is set away from the user to prevent the user from accidentally touching the handle 3 and rotating it.

[0036] See also Figure 5 and Figure 6 , a storage groove 11 adapted for the handle 3 is provided at the top of the filter element 1, and the storage groove 11 is arranged close to the body 2 in the installed state. Specifically, the storage groove 11 is provided at the top of the end cover 14, and includes the bottom of the storage groove 11, the end walls at both ends, and the inner groove wall, that is, the storage groove 11 is an open structure on the outside. The handle 3 is installed on the top of the end cover 14, and can be rotated to a horizontal state and stored in the storage groove 11 under the action of its own weight. The setting of the storage groove 11 can provide an upward support force for the handle 3 to prevent the handle 3 from continuing to rotate downward compared to the horizontal state under the action of its own weight, so as to ensure that the locking state of the handle 3 is in a horizontal state, so as to facilitate unlocking and lifting the filter element 1 when disassembling the filter element 1.

[0037] Furthermore, the arrangement of the storage groove 11 enables the end walls at both ends of the storage groove 11 to prevent the handle 3 from rotating horizontally in the opposite direction, so that the handle 3 can only rotate within a range of 90°, thereby limiting the rotation angle of the handle 3 and making it more convenient to lock the handle 3.

[0038] On the basis of the above structure, the handle 3 of the utility model includes a handle portion 32, and the handle portion 32 is provided with an extension portion 321. In the locked state, the extension portion 321 is located at the top of the handle portion 32 and extends horizontally outward. Specifically, the handle portion 32 is the main body of the handle 3, which is used to hold the filter element 1. The handle portion 32 is an arc-shaped structure, which is convenient for holding. The handle portion 32 is provided with an extension portion 321 so that the handle portion 32 forms a stepped structure. In the locked state, the handle 3 is stored in the storage groove 11, and the stepped structure of the handle portion 32 forms an inward recessed portion and an outward extension portion compared to the storage groove 11. When unlocking is required, the handle 3 is lifted up and rotated by the extension portion 321 for easy operation.

[0039] Both ends of the handle portion 32 are provided with a limiting portion 31, and the limiting portion 31 is provided with a mounting hole 311. The top of the filter element 1 is provided with a matching mounting portion 12 corresponding to the mounting hole 311, and the mounting portion 12 is arranged in the corresponding mounting hole 311, and the mounting hole 311 can rotate relative to the mounting portion 12. Specifically, the inner wall of the groove at both ends of the storage groove 11 is provided with a mounting portion 12 protruding outward corresponding to the mounting hole 311, and the mounting portion 12 is penetrated in the corresponding mounting hole 311, so that the limiting portion 31 can rotate relative to the mounting portion 12, so that the handle 3 can be rotatably installed in the storage groove 11 of the end cover 14. Since the limiting portion 31 is installed at both ends of the handle portion 32, when the handle 3 rotates from a vertical state to a horizontal state due to its own weight, the displacement of the heavier limiting portion 31 relative to the limiting groove 11 is small, and it will not hit the storage groove 11, so as to ensure the stability of the installation of the filter element 1.

[0040] For the center of gravity offset setting of the limiting part 31 of the utility model, it can be symmetrically arranged relative to the handle part 32 in structure, but the weight of the two symmetrical parts is different to achieve the center of gravity offset. In the utility model, the storage slot 11 includes a handle slot 111 adapted to the handle part 32 and a limiting slot 112 adapted to the limiting part 31, the limiting slot 112 is arranged at both ends of the handle slot 111, and the limiting slot 112 extends downward relative to the handle slot 111, and the two mounting parts 12 are relatively convexly arranged on the groove wall of the corresponding limiting slot 112 along the radial direction of the filter element 1. That is, the storage slot 11 is a stepped structure, the handle slot 111 is arranged higher than the limiting slot 112, and correspondingly, the limiting part 31 is asymmetrically arranged relative to the handle part 32. In the vertical state, the limiting part 31 is arranged to be biased toward one side of the storage slot 11 in structure, so that its center of gravity is biased toward the storage slot 11. Therefore, when the handle 3 is placed vertically, the handle 3 will automatically rotate into the storage slot 11 due to the center of gravity offset of the limiting portion 31 to achieve horizontal locking, so that the locking structure of the handle 3 is simple and easy to operate.

[0041] Preferably, both ends of the limiting portion 31 in the extension direction are arc-shaped structures. Correspondingly, both ends of the limiting groove 112 in the extension direction are also adapted arc-shaped structures, so that during the reciprocating rotation of the handle 3, the coordination of the arc-shaped structures can improve the smoothness of the rotation of the limiting portion 31, so as to quickly lock or unlock the handle 3.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The body 2 is provided with a limiting member 23 corresponding to the limiting portion 31, and the limiting member 23 is arranged on the top outer side of the installation cavity 21, and the limiting portion 31 is sandwiched between the groove wall of the limiting groove 112 and the limiting member 23. That is, the limiting portion 31 is rotatably installed in the limiting groove 112, and the two sides of the limiting portion 31 are the inner wall of the limiting groove 112 and the limiting member 23 respectively. The limiting member 23 and the inner wall of the limiting groove 112 limit the limiting portion 31, so as to prevent the limiting portion 31 from being separated from the limiting groove 112 or the installation portion 12, so as to ensure the stable and rotatable connection between the handle 3 and the filter element 1.

[0043] Specifically, the body 2 is provided with a support platform 22, the support platform 22 is provided on the outer periphery of the mounting cavity 21, the stopper 23 is provided on the support platform 22, and the support platform 22 is located below the storage groove 11 in the assembled state. That is, the support platform 22 is provided around the filter element 1 to provide a setting position for the stopper 23. It should be noted that when the stopper 23 is provided on the support platform 22, the stopper 23 is provided close to the edge of the mounting cavity 21 corresponding to the support platform 22 to ensure the stopper 23 has a stopper effect on the stopper 31.

[0044] Furthermore, one end of the limiting portion 31 close to the handle portion 32 extends outward away from the groove wall of the limiting groove 112 to form a convex portion 312. In the locked state, the convex portion 312 is located on the support platform 22 and abuts against the limiting member 23. That is, the convex portion 312 is arranged to extend outward compared to the limiting groove 112, so that it is placed on the support platform 22 in the locked state, so that the supporting platform 22 provides an upward supporting force to the limiting portion 31, that is, the supporting platform 22 and the storage groove 11 simultaneously provide an upward supporting force to the handle 3, further ensuring that the handle 3 is locked in a horizontal state, improving the stability of the locking of the handle 3, and improving the convenience of unlocking. In addition, the convex portion 312 is arranged close to the limiting member 23, so that the limiting portion 31 is limited by the limiting member 23, the supporting platform 22 and the limiting groove 112, further improving the stability of the rotation of the handle 3.

[0045] Therefore, the filter element locking structure of the present invention provides a limit portion 31 with a center of gravity offset on the handle 3, so that the handle 3 rotates to a horizontal state under the action of gravity to be locked, and the locking structure is simple and easy to operate. In addition, the handle 3 of the present invention designs the limit portion 31 so that the limit portion 31 is limited by the limit member 23, the support platform 22 and the limit groove 112, so that the limit portion 31 is limited in the limit groove 112, and the limit portion 31 is ensured to stably rotate relative to the mounting portion 12, thereby improving the stability of the rotation of the handle 3.

[0046] In addition to the above filter element locking structure, the utility model also provides a water purifier, see Figure 1 and Figure 2 , which includes a sealing plate 4 and the above-mentioned filter element locking structure, and the sealing plate 4 is installed at the opening of the installation cavity 21.

[0047] Specifically, the water purifier includes a body 2, and the body 2 is provided with an installation cavity 21 adapted for the filter element 1. In the present utility model, the filter element 1 is a cylindrical structure, which includes a cylindrical filter element body 13 and a cylindrical end cover 14 arranged on the top of the filter element body 13. Correspondingly, the installation cavity 21 is a cylindrical structure to facilitate the installation of the filter element 1. Since a handle 3 is rotatably installed on the top of the end cover 14 of the filter element 1, in order to facilitate the locking or unlocking of the handle 3, the handle 3 should be arranged outside the installation cavity 21. Therefore, the handle 3 is located above the installation cavity 21, that is, the height of the filter element 1 is higher than the height of the installation cavity 21.

[0048] The position where the installation cavity 21 is provided on the machine body 2 is an open structure, and the sealing plate 4 is installed at the opening structure to seal the filter element 1 in the water purifier to achieve the installation of the filter element 1.

[0049] When the filter element 1 needs to be installed, the sealing plate 4 is removed and the handle 3 is rotated to a vertical state so that the user can lift the filter element 1 through the handle 3 and install it in the installation cavity 21 of the body 2. When the filter element 1 is locked and installed in the installation cavity 21, the handle 3 is released so that the handle 3 rotates 90° to a horizontal state due to gravity to be locked in the storage groove 11, and the limiting portion 31 is limited by the limiting member 23, the support platform 22 and the limiting groove 112, ensuring the stable locking of the handle 3, so as to ensure that the filter element 1 will not swing or rotate when it is installed in the water purifier and the handle 3 is used, so as to achieve stable installation of the filter element 1. After the filter element 1 and the handle 3 are locked, the sealing plate 4 is installed to complete the assembly of the water purifier.

[0050] When the filter element 1 needs to be replaced, remove the sealing plate 4, unlock the filter element 1, then lift the handle 3 upwards through the extension portion 321 and rotate it to 90°, lift the filter element 1 out of the installation cavity 21 through the handle 3, replace it with a new filter element 1, and repeat the above installation operation to replace the filter element 1.

[0051] The sealing plate 4 can be installed at the opening of the body 2 by means of snap connection, screw connection, riveting, etc.

[0052] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
