[0028] 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.

[0029] 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.

[0030] Embodiment 1,

[0031] See also Figures 1 to 3 The utility model discloses a water purifier for preventing a filter element 20 from loosening, comprising: a filter element 20 and a body 10, a first locking mechanism is provided at the top end of the filter element 20, a second locking mechanism is provided at the bottom end of the filter element 20, the body 10 has a mounting groove 11, the mounting groove 11 is through-set along the height direction of the body 10, the filter element 20 is mounted in the mounting groove 11, specifically, the first locking mechanism is connected to the top end of the body 10 after the filter element 20 is mounted in the mounting groove 11, and the second locking mechanism is connected to the bottom end of the body 10 after the filter element 20 is mounted in the mounting groove 11, so as to lock the filter element 20.

[0032] On the basis of the above structure, during assembly, the filter element 20 is vertically placed into the installation groove 11 along the height direction of the body 10. Thereafter, it is connected to the top of the body 10 through a first locking mechanism located at the top of the filter element 20, and the second locking mechanism located at the bottom is connected to the bottom of the body 10, so that both ends of the filter element 20 are locked with the two ends of the body 10 after installation, making its structure more stable.

[0033] After the filter element 20 is assembled with the body 10, the weight of the filter element 20 itself or the water inside the filter element 20 is affected by gravity, and the forces of the two usually act on the bottom end of the filter element 20. If only the top end of the filter element 20 is locked, the bottom end of the filter element 20 may shake or displace due to the water pressure of the water flow inside it or other external forces (such as collision with foreign objects), making the filter element 20 unstable, thereby affecting its filtering effect and service life. Therefore, in this embodiment, the top and bottom ends of the filter element 20 are locked. Then, when the weight of the filter element 20 itself or the downward pressure generated when the water in the filter element 20 passes through the filter element 20 acts on the bottom end of the filter element 20, the gravity and the downward pressure both act on the second locking mechanism located at the bottom end of the filter element 20 to increase the locking force of the second locking mechanism, so that its bottom end is more stable after being locked, thereby effectively preventing the filter element 20 from being displaced or shaken under the pressure of the water flow or other external forces, making the entire structure more stable during use.

[0034] Specifically, the first locking mechanism and the second locking mechanism can be formed by a block, a strip or a buckle formed at the top and the bottom of the filter element 20. During assembly, a groove can be provided at the top and the bottom of the body 10, so that the first locking mechanism and the second locking mechanism can be detachably connected to the body 10 by means of a snap connection, so that the filter element 20 can be locked or unlocked with the top of the body 10 by means of the first locking mechanism and the second locking mechanism.

[0035] Of course, the specific first locking mechanism and the second locking mechanism can also be formed by a slot or locking slot 50 formed at the top of the filter element 20. During assembly, a block, a strip or a buckle structure matching the first locking mechanism and the second locking mechanism are correspondingly arranged at the top and the bottom of the body 10. Similarly, the filter element 20 and the body 10 can be connected by the first locking mechanism and the second locking mechanism, which is convenient for locking and unlocking at any time. In this way, the filter element 20 does not need to use other tools during the assembly process with the body 10, and can be disassembled and assembled only by snap connection. The structure is simple and easy to disassemble and assemble. After assembly, the top and the bottom of the filter element 20 are locked with the body 10, and the structure is more stable.

[0036] Furthermore, the first locking mechanism specifically includes a first locking portion and a second locking portion. During assembly, the first locking portion is set at the top of the filter element 20, and the second locking portion is set at the top of the body 10. The first locking portion is engaged with the second locking portion.

[0037] On the basis of this structure, the first locking part can be formed by a block, a strip or a buckle formed at the top of the filter element 20, and the second locking part can be a slot or a locking slot 50 formed at the top of the body 10 and corresponding to the first locking part so that the two can be snap-connected and detachable, so that the filter element 20 is locked or detached from the top of the body 10; of course, the first locking part can also be a slot or a locking slot 50 formed at the top of the body 10 and corresponding to the first locking part, and the second locking part can be a buckle or a strip formed on the body 10 to match it, which can also achieve a snap connection, so that the filter element 20 is locked or detached from the top of the body 10.

[0038] Preferably, the first locking portion in this embodiment is a snap-fit ​​block 22 arranged at the top of the filter element 20, and the second locking portion is a snap-fit ​​groove 12 arranged at the top of the body 10. Specifically, the snap-fit ​​groove 12 can be located above the end wall of the mounting groove 11 so that the snap-fit ​​block 22 can be snapped into the snap-fit ​​groove 12.

[0039] During specific assembly, when the filter element 20 is installed in the mounting groove 11 along the height direction of the mounting groove 11, the filter element 20 slowly approaches the second locking portion under the action of external force until the snap-fit ​​block 22 approaches the snap-fit ​​groove 12, then it can slide into and snap-fit ​​into the snap-fit ​​groove 12, so that its top end is locked with the body 10.

[0040] It should be noted that, during assembly, a slope or an arc surface can be set on the end wall of the clamping block 22 or the groove wall of the clamping groove 12. In this way, when the clamping block 22 moves to the clamping groove 12, due to the presence of the slope or the arc surface, the slope or the arc surface design provides a gradually transitioning guide surface, so that the clamping block 22 can gradually approach and finally enter the clamping groove 12 according to a predetermined path and angle. This design can reduce the resistance of the clamping block 22 during the clamping process, allowing it to enter the clamping groove 12 more smoothly; similarly, when the clamping block 22 needs to be disengaged from the clamping groove 12, it is easier to slide out of the clamping groove due to the presence of the slope or the arc surface.

[0041] Of course, the clamping block 22 can also be made of elastic materials such as plastic or rubber. When the elastic clamping block 22 is inserted into the clamping groove 12, due to the elasticity of the material, it will be squeezed and deformed. Once it is inserted into place and the external force disappears, the elastic clamping block 22 will try to return to its original state. This restoring force creates a tight connection between the clamping block 22 and the clamping groove 12, thereby achieving locking; similarly, when the elastic clamping block 22 is inserted into the clamping groove 12, if it is subjected to an external force in the opposite direction of the insertion direction, the clamping block 22 will produce a corresponding deformation, so that it can be detached from the clamping groove 12, thereby achieving the locking and unlocking of the clamping block 22 and the clamping groove 12, and then the filter element 20 and the body 10 can be disassembled.

[0042] Furthermore, a handle 21 is provided at the top of the filter element 20, and the handle 21 is rotatably connected to the filter element 20, and rotates to move closer to or away from the filter element 20 when subjected to force, wherein the handle 21 covers the outer periphery of the filter element 20 when rotating close to the filter element 20 and is spaced from the inner wall of the mounting groove 11 to form a snap-in groove 12, and a snap-in block 22 is provided on the side of the handle 21, and extends into or detaches from the snap-in groove 12 when the handle 21 rotates, so that the top of the filter element 20 is connected to or detached from the body 10.

[0043] Specifically, since a handle 21 is provided at the top of the filter element 20, the filter element 20 can be held by the handle 21, which is convenient for the user to disassemble and assemble the filter element 20. During assembly, the operator can first apply an external force to the handle 21 to rotate it and move it away from the filter element 20, so that the operator can lift and hold the filter element 20. Then, after the filter element 20 is installed in the installation groove 11, the handle 21 is rotated again to move it close to the filter element 20 and seal on the outer periphery of the filter element 20 and be flush with the outer peripheral end surface of the filter element 20, so that the outer periphery of the filter element 20 is smoother and simpler.

[0044] In addition, if the clamping block 22 is arranged at the top of the filter element 20 and not on the handle 21, the bottom of the filter element 20 may not be completely locked after the operator assembles the filter element 20 into the installation slot 11, and the clamping block 22 at the top has already been locked with the clamping slot 12, so that the operator needs to unlock the clamping block 22 again and reassemble it, which is time-consuming and laborious for the operator. Therefore, in this embodiment, the clamping block 22 is arranged on the side of the handle 21, and the handle 21 is sealed when it is rotated close to the filter element 20. The outer periphery of the cover filter element 20 is then joined to the inner wall of the mounting groove 11 to form a snap-fit ​​groove 12. In this way, when the operator rotates the handle 21 to move it away from the filter element 20, the snap-fit ​​block 22 is also away from the filter element 20, and the snap-fit ​​groove 12 has not yet been formed. Therefore, the snap-fit ​​block 22 will not extend into the snap-fit ​​groove 12 to lock when the handle 21 is away from the filter element 20, so as to prevent the bottom end of the filter element 20 from being completely fixed while the top end is already locked, resulting in a structural instability. The structure is more practical.

[0045] Furthermore, the clamping block 22 in this embodiment is an elastic block. Specifically, when the elastic block is inserted into the clamping block 22 , it can provide an elastic stress to drive the elastic block to be clamped into or out of the clamping slot 12 .

[0046] Specifically, since the snap-in block 22 is an elastic block, due to its own elastic force, it will be squeezed and deformed to a certain extent after being snapped into the snap-in groove 12. Once it is snapped into place and the external force disappears, the elastic snap-in block 22 will try to return to its original state. This restoring force creates a tight connection between the snap-in block 22 and the snap-in groove 12, thereby achieving locking; similarly, when the elastic snap-in block 22 is snapped into the snap-in groove 12, if it is subjected to an external force in the opposite direction of the snap-in direction, the snap-in block 22 will produce a corresponding deformation, allowing it to detach from the snap-in groove 12, thereby achieving the locking and unlocking of the snap-in block 22 and the snap-in groove 12, thereby making the top end of the filter element 20 and the top end of the body 10 detachable.

[0047] Furthermore, the second locking mechanism includes a third locking portion and a fourth locking portion. Specifically, the third locking portion is arranged at the bottom of the filter element 20, and the fourth locking portion is arranged at the bottom end of the body 10 and located on the inner wall of the installation groove 11, so that the third locking portion is engaged and connected with the fourth locking portion.

[0048] On this basis, the third locking portion can be formed by a block, a strip or a buckle structure formed at the bottom end of the filter element 20, and the fourth locking portion can be a slot or a locking slot 50 structure formed at the bottom end of the body 10 and corresponding to the first locking portion so that the two can be snap-connected and detachable, so that the filter element 20 is locked or detached from the lower end of the body 10; of course, the third locking portion can also be a slot or a locking slot 50 structure formed at the bottom end of the body 10 and corresponding to the fourth locking portion, and the fourth locking portion can be a buckle or a strip structure formed on the body 10 that matches it, which can also achieve a snap connection, so that the filter element 20 is locked or detached from the bottom end of the body 10.

[0049] Embodiment 2,

[0050] On the basis of Example 1, in this embodiment, a locking groove is provided at the bottom of the mounting groove 11 (in this embodiment, the locking groove is formed on the groove wall of the mounting groove 11, not shown in the figure), and the specific locking groove is arranged along the inner wall of the mounting groove 11, and the locking groove is formed as a fourth locking portion, and a snap-fit ​​strip 23 is provided at the bottom of the filter element 20 to form a third locking portion through the snap-fit ​​strip 23. The snap-fit ​​strip 23 is snapped into the locking groove after the filter element 20 is installed in the mounting groove 11 to lock the bottom of the filter element 20, and the snap-fit ​​strip 23 is made of elastic material.

[0051] On the basis of this structure, during assembly, the filter element 20 is slowly placed into the installation groove 11. When the snap-in strip 23 at the bottom end of the filter element 20 is close to the locking groove at the bottom of the installation groove 11, since the snap-in strip 23 is made of elastic material, due to its own elastic force, it will be squeezed and deformed to a certain extent after being snapped into the locking groove. Once it is snapped into place and the external force disappears, the elastic snap-in block 22 will try to return to its original state. This restoring force creates a tight connection between the snap-in strip 23 and the locking groove, thereby achieving locking; similarly, when the elastic snap-in strip 23 is snapped into the snap-in groove 12, if it is subjected to an external force in the opposite direction of the snap-in direction, the snap-in strip 23 will produce a corresponding deformation, so that it can be detached from the locking groove, thereby making the bottom end of the filter element 20 and the bottom end of the body 10 detachable.

[0052] Specifically, the clamping strip 23 can be made of elastic plastic or rubber or other elastic materials such as spring buckles or elastic sheets or other elastic structures for clamping.

[0053] Embodiment 3,

[0054] See also Figure 4 On the basis of embodiment 1, this embodiment further includes a mounting seat 30, which is rotatably mounted at the bottom of the mounting groove 11, and a locking groove 50 (such as Figure 4 As shown, the locking groove 50 is formed on the mounting seat), the locking groove 50 is formed as a fourth locking portion, and a clamping strip 23 is provided at the bottom of the filter element 20, the clamping strip 23 is formed as a third locking portion, and the clamping strip 23 extends into the locking groove 50 after the filter element 20 is installed to the mounting seat 30. When the mounting seat 30 is rotated under force, the groove wall of the locking groove 50 abuts against the outer periphery of the clamping strip 23 to lock the clamping strip 23.

[0055] On this basis, during assembly, the mounting seat 30 is rotatably installed at the bottom of the mounting groove 11. By setting a locking groove 50 at the bottom of the mounting groove 11 and setting a snap-on strip 23 at the bottom of the filter element 20, the locking groove 50 is formed as a fourth locking portion, and the snap-on strip 23 is formed as a third locking portion. Specifically, the snap-on strip 23 can pass through the mounting seat 30 and extend into the locking groove 50 after the filter element 20 is installed on the mounting seat 30. Thereafter, the mounting seat 30 is rotated, and the groove wall of the locking groove 50 will produce relative movement with the snap-on strip 23. This relative movement will cause the groove wall to gradually press against the snap-on strip 23. As the mounting seat 30 continues to rotate, the abutment force of the groove wall of the locking groove 50 on the snap-on strip 23 gradually increases until a sufficiently large friction force is reached, so that the snap-on strip 23 is firmly locked in the groove. This locking structure has the characteristics of simplicity and reliability, and can be implemented without a complex transmission mechanism or control system to meet the requirements for locking force in different application scenarios. Therefore, it is simple to assemble and has a wider applicability.

[0056] It should be noted that, on this basis, the mounting seat 30 can be pivotally connected to the bottom of the mounting groove 11 through a rotating shaft or a rotating bearing or other devices that can realize an adapter connection, and a limiting member (such as a limiting strip or a limiting block or other structures) or a limiting slot or other structures are set in the mounting groove 11, so that the mounting seat 30 can be locked after being rotated to lock the snap-in strip 23, to prevent the mounting seat 30 from loosening after rotation and the snap-in strip 23 also loosening synchronously.

[0057] Embodiment 4,

[0058] See also Figures 5 to 7 On the basis of embodiment 1, this embodiment further includes a locking plate 40, which is slidably mounted on the bottom of the mounting groove 11 and is used to slide when subjected to force, the filter element 20 is connected to the locking plate 40, and a clamping strip 23 is provided on the filter element 20, the clamping strip 23 forms a third locking portion, and a locking groove 50 is provided on the locking plate 40 (on this basis, as shown in FIG. Figure 7 The locking groove 50 is formed on the locking plate 40, and the snap-in strip 23 extends into the locking groove 50 when the filter element 20 is connected to the locking plate 40. The groove wall of the locking groove 50 abuts against the outer periphery of the snap-in strip 23 when the locking plate 40 slides to lock the snap-in strip 23.

[0059] On the basis of this structure, the snap-fit ​​strip 23 arranged at the bottom of the filter element 20 forms a third locking part, and the locking groove 50 on the locking plate 40 forms a fourth locking part. When the filter element 20 and the locking plate 40 are installed, the snap-fit ​​strip 23 extends into the locking groove 50. At this time, the operator can apply external force to the locking plate 40 to make the locking plate 40 slide. During the sliding process of the locking plate 40, the locking groove 50 also moves. As the locking groove 50 moves, the abutment force of the groove wall of the locking groove 50 on the snap-fit ​​strip 23 gradually increases until a sufficiently large friction force is reached, so that the snap-fit ​​strip 23 is firmly locked in the groove. The entire locking method can be realized without a complicated transmission mechanism or control system, and is therefore simple to assemble and has a wider range of applicability.

[0060] Similarly, after the locking plate 40 slides to the point where the snap-fit ​​strip 23 is completely locked, a limiting member (a structure such as a snap or a limiting strip) corresponding to the outer periphery of the locking plate 40 can be set in the installation groove 11, or a limiting groove or other structure can be set, so that the outer periphery of the locking plate 40 can be locked after sliding to a certain position to prevent it from moving and causing structural instability.

[0061] Based on the above structure, a pressing block 13 is provided on the inner wall of the mounting groove 11, and a protruding block 41 is provided at one end of the locking plate 40. The other end of the locking plate 40 is abutted against the inner wall of the mounting groove 11 through an elastic component 42. The elastic component 42 can provide an elastic stress to drive the protruding block 41 to move closer to or away from the pressing block 13. When the protruding block 41 moves closer to the pressing block 13, it abuts against it to lock the locking plate 40.

[0062] Specifically, after the filter element 20 is assembled, the snap-fit ​​strip 23 is extended into the locking groove 50 on the locking plate 40. At this time, since the protruding block 41 on the locking plate 40 is against the inner wall of the mounting groove 11, and the elastic component 42 at the other end provides the locking plate 40 with a continuous thrust in the direction of the locking groove 50 under the action of its own elastic force, when the snap-fit ​​strip 23 is inserted into the locking groove 50, the thrust of the spring will cause the groove wall of the locking groove 50 to tightly press the outer periphery of the snap-fit ​​strip 23, thereby helping the locking plate 40 to tightly lock the snap-fit ​​strip 23 in the groove, making the position of the snap-fit ​​strip 23 in the locking groove 50 more stable, thereby locking the filter element 20 in the mounting groove 11 to prevent it from loosening due to external factors (such as external thrust or vibration, etc.).

[0063] When the filter element 20 needs to be unlocked from the installation groove 11, the operator applies external force to the locking plate 40 to compress the elastic component 42. The groove wall of the locking groove 50 can then loosen the snap-on strip 23, so that the filter element 20 can be in an unlocked state and detached from the locking plate 40. The entire design structure is simple and practical to assemble.

[0064] It should be noted that the elastic component 42 in this embodiment can be formed by existing structures such as springs, elastic columns, or elastic sheets.

[0065] 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.
