Detailed Embodiments

[0032] In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are to be regarded as illustrative rather than restrictive in nature.

[0033] See Figures 1 - 5, showing a locking member mounting structure according to a preferred embodiment of the present invention, including:

[0034] The mounting base 1 has a receiving cavity 113 and a limiting groove 1111. The limiting groove 1111 is provided on the side wall of the receiving cavity 113 and is arranged around the vertical center line of the receiving cavity 113.

[0035] The locking member 2 is rotatably arranged in the receiving cavity 113. The locking member 2 is provided with a limiting protrusion 21. The limiting protrusion 21 is slidably engaged with the limiting groove 1111 to limit the upward movement of the locking member 2 along the receiving cavity 113.

[0036] In the locking member mounting structure of the present invention, by providing the limiting groove 1111 on the side wall of the receiving cavity 113 and the limiting protrusion 21 on the locking member 2, the rotation of the locking member 2 is guided by the sliding fit between the limiting protrusion 21 and the limiting groove 1111, making the rotation of the locking member 2 smoother. At the same time, the upward movement of the locking member 2 along the receiving cavity 113 can be restricted by the cooperation between the limiting protrusion 21 and the limiting groove 1111, so that the locking member 2 is reliably installed in the receiving cavity 113, preventing the locking member 2 from randomly disengaging from the set installation position. There is no need to provide a pressing plate on the mounting base 1 to restrict the upward movement of the locking member 2, saving a component, simplifying the structure, improving the installation efficiency, and reducing the cost.

[0037] See Figure 4 , in an embodiment, the limiting groove 1111 has a laterally extending section 11111 and a mounting opening 11112. The laterally extending section 11111 is slidably engaged with the limiting protrusion 21 to limit the upward movement of the locking member 2 along the receiving cavity 113. The mounting opening 11112 is located on one side of the top of the laterally extending section 11111, and the mounting opening 11112 is for the vertical entry and exit of the limiting protrusion 21 into and out of the laterally extending section 11111. In this way, during the process of installing the locking member 2 into the receiving cavity 113, the limiting protrusion 21 can be aligned with the mounting opening 11112, then the locking member 2 is pushed downward to the laterally extending section 11111, and finally the locking member 2 is rotated to drive the limiting protrusion 21 to move to one end of the laterally extending section 11111 away from the mounting opening 11112, and the installation can be completed. The installation operation is convenient.

[0038] See Figure 3 , in an embodiment, the locking member mounting structure further includes:

[0039] The elastic member 3 has one end connected to the mounting base 1 and the other end connected to the locking member 2. The elastic member 3 is used to provide a driving force to the locking member 2 to limit the limiting protrusion 21 to the end of the transverse extension section 11111 away from the mounting opening 11112, so as to reliably limit the limiting protrusion 21 in the transverse extension section 11111 and prevent the limiting protrusion 21 from sliding into the mounting opening 11112 and disengaging from the limiting groove 1111. Only by applying a rotational force to the locking member 2 that overcomes the above driving force can the limiting protrusion 21 slide to the end of the transverse extension section 11111 close to the mounting opening 11112. At this time, since the elastic member 3 connects the mounting base 1 and the locking member 2, the elastic member 3 can also be used to prevent the limiting protrusion 21 from disengaging from the mounting opening 11112, improving the structural reliability and stability.

[0040] In one embodiment, the elastic member 3 can be a spring. Of course, in other embodiments, the elastic member 3 can also be an elastic structure such as a spring piece.

[0041] See Figure 4 , in one embodiment, the limiting groove 1111 further has a vertical extension section 11113. The lower end of the vertical extension section 11113 communicates with one side of the top of the transverse extension section 11111, and the upper end of the vertical extension section 11113 communicates with the mounting opening 11112. This vertical extension section 11113 can increase the distance between the mounting opening 11112 and the transverse extension section 11111, making it more difficult for the limiting protrusion 21 to slide into the mounting opening 11112 and improving the connection reliability between the limiting groove 1111 and the limiting protrusion 21.

[0042] See Figure 4 , in one embodiment, the cross-sectional area of the upper end of the vertical extension section 11113 gradually increases from bottom to top, that is, the vertical cross-section of the upper end of the vertical extension section 11113 is conical, which can play a guiding role in the installation of the limiting protrusion 21 to guide the limiting protrusion 21 to be smoothly installed into the limiting groove 1111, improving the installation smoothness of the locking member 2 and making the installation of the locking member 2 more convenient.

[0043] See Figure 4, in one embodiment, the mounting base 1 is provided with a limiting portion 121. The limiting portion 121 extends into the transverse extension section 11111 and is located at one end close to the mounting opening 11112. The limiting portion 121 can abut against the limiting protrusion 21 to limit the sliding of the limiting protrusion 21 to the mounting opening 11112. In this way, during the rotation of the locking member 2 with the limiting protrusion 21 towards the mounting opening 11112, the limiting protrusion 21 abuts against the limiting portion 121, which blocks the sliding of the limiting protrusion 21 to the mounting opening 11112, thereby restricting the limiting protrusion 21 from passing through the mounting opening 11112 and disengaging from the limiting groove 1111, enabling the reliable cooperation between the limiting protrusion 21 and the transverse extension section 11111, and improving the structural reliability and stability.

[0044] See Figures 1 - 2 , in one embodiment, the mounting base 1 includes:

[0045] a mounting body 11 having a receiving cavity 113 and a limiting groove 1111;

[0046] a waterway adapter 12 disposed on the bottom of the mounting body 11, and the waterway adapter 12 is provided with a limiting portion 121. That is, the mounting base 1 is composed of the separately provided mounting body 11 and the waterway adapter 12. This mounting base 1 has a lower manufacturing difficulty and is convenient for assembly. At the same time, by providing the limiting portion 121 on the original waterway adapter 12 of the water purification device, the utilization rate of the waterway adapter 12 can be improved, eliminating the need for additional configuration of limiting parts and reducing the number of components, thereby simplifying the structure, facilitating further improvement of the installation efficiency, and also helping to further reduce costs.

[0047] See Figure 4 , in one embodiment, the mounting base 1 further has a positioning groove 1112 disposed on the bottom wall of the receiving cavity 113 and surrounding the rotation center line of the locking member 2;

[0048] The bottom of the locking member 2 is provided with a positioning protrusion 22, and the positioning protrusion 22 is slidably engaged with the positioning groove 1112. In this way, through the cooperation between the positioning protrusion 22 and the positioning groove 1112, on the one hand, it can play a role in installation positioning, facilitating the quick installation of the locking member 2 into the receiving cavity 113, and on the other hand, it can play a role in rotation guiding, making the rotation of the locking member 2 smoother.

[0049] See Figure 1 , for the convenience of processing and installation, the mounting body 11 includes a base 111 and a main housing 112. The base 111 is connected to the waterway adapter 12, and the main housing 112 is disposed on the top of the base 111. The main housing 112 and the base 111 enclose the receiving cavity 113.

[0050] See Figures 1 - 2 andFigures 4 - 5 , a preferred embodiment of the utility model provides a filter element installation device, including a filter element 4 and the above-mentioned locking member installation structure;

[0051] The filter element 4 is detachably disposed in the accommodating cavity 113 , and the filter element 4 is provided with a first locking portion 41 ;

[0052] The locking member 2 is provided with a second locking portion 23, which has a first position connected to the filter element 4 to restrict the filter element 4 in the accommodating chamber 113. The second locking portion 23 also has a second position disconnected from the filter element 4 to allow the filter element 4 to be able to detach from the accommodating chamber 113. The locking member 2 rotates to switch the second locking portion 23 between the first position and the second position to be able to lock and unlock the filter element 4.

[0053] The filter element installation device of the present invention adopts the above-mentioned locking piece installation structure, and can also utilize the limiting protrusion 21 and the limiting groove 1111 to slide and cooperate to realize the rotation guidance of the locking piece 2, so that the locking piece 2 can rotate more smoothly. At the same time, the limiting protrusion 21 and the limiting groove 1111 can also be utilized to limit the locking piece 2 from moving upward along the accommodating cavity 113, so that the locking piece 2 can be reliably installed in the accommodating cavity 113, and the locking piece 2 can be prevented from arbitrarily leaving the set installation position. There is no need to set a pressure plate on the installation base 1 to limit the locking piece 2 from moving upward, which saves a component, simplifies the structure, can improve the installation efficiency, and at the same time, helps to reduce costs. In addition, by turning the locking piece 2 toward the first direction and rotating it, the second locking portion 23 can be switched from the first position to the second position, thereby unlocking the filter element 4. By turning the locking piece 2 toward the second direction and rotating it, the second locking portion 23 can be switched from the second position to the first position, thereby locking the filter element 4. Whether locking or unlocking, it is only necessary to turn the locking piece 2 and rotate it. Compared with the structure of the prior art of turning the filter element 4 to rotate and unlock, the required locking and unlocking torque is smaller. Therefore, the user only needs to use less force to lock and unlock the filter element 4. Locking and unlocking are more labor-saving, which can provide users with a better user experience.

[0054] It should be noted that the locking member 2 is driven by the elastic component 3 to maintain the second locking portion 23 in the first position, ensuring that the locking member 2 and the filter element 4 are reliably connected together. Only when a rotational force that overcomes the above-mentioned driving force is applied to the locking member 2 can the second locking portion 23 be rotated to the second position.

[0055] The first direction may be a clockwise direction or a counterclockwise direction, and the second direction is opposite to the first direction.

[0056] See also Figures 3 - 4, in one embodiment, the second locking portion 23 has a locking groove 231, and the locking groove 231 cooperates with the first locking portion 41. By the cooperation of the locking groove 231 and the first locking portion 41, the contact area between the second locking portion 23 and the first locking portion 41 can be increased, so that the second locking portion 23 can be reliably maintained in the first working position, the locking reliability of the filter element 4 can be improved, and the structural reliability is higher.

[0057] In other embodiments, the bottom surface of the second locking portion 23 cooperates with the top surface of the first locking portion 41. In this way, the filter element 4 can also be locked.

[0058] See Figure 5 , in one embodiment, the first locking portion 41 is provided with a first installation guiding inclined surface 411;

[0059] See Figures 3 - 4 , the top of the second locking portion 23 is provided with a second installation guiding inclined surface 232, and the second installation guiding inclined surface 232 is slidably matched with the first installation guiding inclined surface 411 to guide the first locking portion 41 to slide to cooperate with the locking groove 231. In this way, during the process of inserting the filter element 4 into the accommodating cavity 113, the first installation guiding inclined surface 411 and the second installation guiding inclined surface 232 are slidably matched, playing a role of installation guiding, and the installation is smoother, which can improve the installation efficiency of the filter element 4. At the same time, during the sliding cooperation between the first installation guiding inclined surface 411 and the second installation guiding inclined surface 232, the filter element 4 can apply a rotational force to the locking member 2 to overcome the second driving force of the second elastic member 3, so that the second locking portion 23 is switched from the first working position to the second working position, playing a role of avoiding the first locking portion 41, ensuring that the first locking portion 41 can enter the set position of the locking member 2. After the first installation guiding inclined surface 411 disengages from the second installation guiding inclined surface 232, the locking member 2 rotates along the first direction under the second driving force of the second elastic member 3, so that the second locking portion 23 is reset to the first working position, thereby enabling the locking groove 231 to cooperate with the first locking portion 41, ensuring reliable locking of the filter element 4, and the structural reliability is higher.

[0060] In one embodiment, the locking member 2 is arranged around the vertical center line of the accommodating cavity 113, so that the locking member 2 forms an annular structure to facilitate increasing the structural stability.

[0061] In one embodiment, the number of the first locking portions 41 is multiple, and the multiple first locking portions 41 are arranged at intervals around the vertical center line of the filter element 4;

[0062] The number of the second locking portions 23 is multiple, and the multiple second locking portions 23 are arranged at intervals around the vertical center line of the accommodating cavity 113. Each second locking portion 23 respectively cooperates with the corresponding first locking portion 41 to enhance the locking reliability of the filter element 4, and the structural reliability is higher.

[0063] A preferred embodiment of the present utility model provides a water purification device, including the above-mentioned filter element installation device.

[0064] For the water purification device of the present utility model, due to the adoption of the above-mentioned filter element installation device, it can also use the sliding fit between the limit protrusion 21 and the limit groove 1111 to realize the rotation guidance of the locking member 2, making the rotation of the locking member 2 smoother. At the same time, it can also use the cooperation between the limit protrusion 21 and the limit groove 1111 to limit the upward movement of the locking member 2 along the accommodation cavity 113, so that the locking member 2 is reliably installed in the accommodation cavity 113, preventing the locking member 2 from randomly disengaging from the set installation position. There is no need to set a pressing plate on the installation base 1 to limit the upward movement of the locking member 2, saving a component, simplifying the structure, improving the installation efficiency, and at the same time, helping to reduce costs.
