DETAILED DESCRIPTION

[0038] In order to make the above objectives, features and advantages of the present application more apparent, a detailed description of the specific embodiments of the present application will be given below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0039] As shown in FIG. 1, in some embodiments, the present application provides a water purifying device 10, which comprises a filter bottle 11, a filter core 12, a lifting assembly 13 and a force applying assembly 14. Figure 1 The filter bottle 11 has an accommodating space 116 therein, and the filter core 12 is detachably installed in the accommodating space 116, and the direction in which the filter core 12 is detached from the filter bottle 11 is a first direction, as shown by the arrow F1 in FIG. 1. Figure 1

[0040] ​​The lifting assembly 13 is disposed on the filter bottle 11, and the direction in which the moving part of the lifting assembly 13 moves relative to the fixed part of the lifting assembly 13 is parallel to the first direction.

[0041] The force-applying component 14 is disposed on the movable part of the lifting component 13. The relative position of the force-applying component 14 and the movable part is fixed in the lifting direction of the lifting component 13. The force-applying component 14 is used to apply force to the filter element 12 in the accommodating space 116 so that it can rise and fall together with the movable part.

[0042] When disassembling or assembling the filter element 12, the force-applying component 14 first provides force to the filter element 12 so that the relative position of the filter element 12 with respect to the force-applying component 14 in the lifting direction is fixed. Then, the lifting component 13 operates to move the force-applying component 14 in the lifting direction, so that the filter element 12 can be quickly and conveniently disassembled or assembled from the filter bottle 11.

[0043] In some embodiments, the force-applying component 14 is at least partially capable of supporting the filter element 12, providing a supporting force to the filter element 12 in a first direction. When the lifting component 13 is raised or lowered, the force-applying component 14 can lift the filter element 12.

[0044] For example, in one embodiment, the force-applying component 14 includes a support member that is supported below the filter element 12. The support member is connected to the movable part of the lifting component 13. When the movable part moves up and down relative to the fixed part, the support member moves up and down synchronously, and the filter element 12 moves up and down together with the support member.

[0045] In other embodiments, the force-applying component 14 can clamp the filter element 12 and generate friction between the filter element 12 and the filter element 12, the direction of which is parallel to the first direction. After the force-applying component 14 clamps the filter element 12, the force-applying component 14 can move the filter element 12 up and down together with the lifting component 13.

[0046] For example, in one embodiment, the force-applying component 14 includes a clamp, which is disposed on the movable part. The clamp can hold the filter element 12, so that when the movable part moves up and down relative to the fixed part, the clamp can move up and down synchronously with the filter element 12.

[0047] Furthermore, in some embodiments, such as Figure 1 As shown, the fixed part of the lifting assembly 13 includes a first driving member 131, and the movable part of the lifting assembly 13 includes a first moving member 132. The first moving member 132 can move back and forth relative to the filter bottle 11 in a direction parallel to the first direction. The first driving member 131 and the first moving member 132 are in a transmission cooperation to drive the first moving member 132 to move back and forth relative to the filter bottle 11 in a direction parallel to the first direction.

[0048] The force applying assembly 14 is arranged on the first moving part 132, and the relative position between the force applying assembly 14 and the first moving part 132 is fixed in the moving direction of the first moving part 132.

[0049] When the filter element 12 needs to be lifted, the first driving part 131 starts and drives the first moving part 132 to move. Since the relative position between the force applying assembly 14 and the first moving part 132 is fixed in the moving direction, the force applying assembly 14 will also be lifted when the first moving part 132 moves, and then the filter element 12 will also be lifted together with the force applying assembly 14.

[0050] Specifically, in one embodiment, as shown in Figure 1 , Figure 2 and Figure 5 , the first driving part 131 includes a first motor, the first motor is arranged on the filter bottle 11, a first transmission gear 135 is arranged on the rotating shaft of the first motor, and the first moving part 132 is a rack. The first transmission gear 135 is engaged with the first moving part 132. The length direction of the first moving part 132 is parallel to the first direction, and the first moving part 132 is movable relative to the filter bottle 11 in the length direction of the first moving part 132. When the first motor is started, the first transmission gear 135 rotates and then the first moving part 132 moves.

[0051] Further, as shown in Figure 2 and Figure 3 , in some embodiments, a through hole 133 is arranged on the movable part, and the force applying assembly 14 is partially inserted into the through hole 133. The penetrating direction of the through hole 133 intersects the first direction, and the force applying assembly 14 is slidable in the through hole 133.

[0052] The force applying assembly 14 is inserted into the through hole 133, and the force applying assembly 14 is movable relative to the movable part in the penetrating direction of the through hole 133. If the force applying assembly 14 slides relative to the filter bottle 11 in the penetrating direction of the through hole 133, the force applying assembly 14 will not move with the movable part, and at this time the movable part will not move relative to the filter bottle 11. Further, the force applying assembly 14 has more movement modes, for example, the force applying assembly 14 can change the action relationship between the force applying assembly 14 and the filter element 12 by sliding relative to the filter bottle 11. The force applying assembly 14 sliding relative to the filter bottle 11 can switch between the state of clamping the filter element 12 and the state of releasing the filter element 12, which meets the requirements of more use occasions.

[0053] When the movable part is lifted relative to the fixed part, the force applying assembly 14 inserted into the through hole 133 will be lifted with the movable part.

[0054] In some embodiments, the penetrating direction of the through hole 133 is perpendicular to the first direction.

[0055] Specifically, as shown in Figure 2 andFigure 3 As shown, the movable component further comprises a mounting buckle 134 assembled with the first moving part 132 and forming a through hole 133.

[0056] When the first moving part 132 is a rack, the two ends of the mounting buckle 134 can be inserted into the notches of the rack, and the mounting buckle 134 and the first moving part 132 enclose the through hole 133.

[0057] Alternatively, the first driving part 131 can also be a hydraulic driving part, a pneumatic driving part, or other driving elements capable of realizing the telescopic function.

[0058] Further, as shown, Figures 1 to 5 In some embodiments, the force applying assembly 14 comprises a second driving part 141 and a second moving part 142, the second moving part 142 being movable back and forth in a second direction relative to the filter bottle 11, the second direction intersecting the first direction. In some cases, the second direction is perpendicular to the first direction, as shown by the arrow F2 in Figure 1 The second moving part 142 cooperates with the movable component, the relative position of the second moving part 142 to the movable component in the lifting direction of the lifting assembly 13 being fixed, and the second moving part 142 being movable relative to the movable component in the second direction.

[0059] The second driving part 141 and the second moving part 142 are in transmission cooperation for driving the second moving part 142 to move back and forth in the second direction relative to the filter bottle 11, so as to switch between the clamping state and the release state. When the second moving part 142 is in the clamping state, the second moving part 142 can act on the filter core 12 and apply a force to it so that it can be lifted together with the movable component; when the second moving part 142 is in the release state, the second moving part 142 is disengaged from the filter core 12.

[0060] During the process of disassembling the filter core 12, the second driving part 141 can drive the second moving part 142 to switch to the clamping state, and then the lifting assembly 13 operates, the movable component is lifted relative to the fixed component, after the filter core 12 is moved to the desired position, the second driving part 141 can drive the second moving part 142 to switch to the release state, and then the filter core 12 is taken out.

[0061] When installing the filter core 12, the filter core 12 is initially placed in the filter bottle 11 so that the filter core 12 is located at a position that can be clamped by the second moving part 142, and then the second driving part 141 drives the second moving part 142 to switch to the clamping state, the movable component is lowered relative to the fixed component, and the filter core 12 is brought to the desired position by the second moving part 142.

[0062] As shown, Figure 2 and Figure 3As shown in some embodiments, the position on the movable component that cooperates with the second moving member 142 is provided with a through hole 133, the second moving member 142 is inserted into the through hole 133 along the second direction, and the second moving member 142 can slide in the through hole 133. The through hole 133 is parallel to the second direction in the direction of penetration, and the relative position of the movable component with respect to the filter bottle 11 is fixed when the second moving member 142 moves along the second direction; the second moving member 142 rises and falls with the movable component.

[0063] In one embodiment, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the second driving member 141 is slidably mounted on the filter bottle 11, and the direction in which the second driving member 141 is slidable with respect to the filter bottle 11 is parallel to the first direction. The relative position of the second moving member 142 with respect to the second driving member 141 in the lifting direction of the lifting assembly 13 is fixed. When the movable component rises and falls with the second moving member 142, the second driving member 141 rises and falls synchronously.

[0064] Specifically, the second driving member 141 can include a second motor, the second motor is slidably mounted on the filter bottle 11, the direction in which the second motor is slidable with respect to the filter bottle 11 is parallel to the first direction, and a second transmission gear 143 can be provided on the rotating shaft of the second motor. The second moving member 142 is a rack, and the second transmission gear 143 is engaged with the second moving member 142.

[0065] Alternatively, the second driving member 141 can also be a hydraulic driving member, a pneumatic driving member, or other driving elements that can realize the telescopic function.

[0066] Further, in some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the first direction is upward along the longitudinal direction, the second driving member 141 is located above the second moving member 142, and the second moving member 142 can support the second driving member 141 to slide upward. When the movable component rises and falls with the second moving member 142, the second moving member 142 can rise and fall with the second driving member 141 synchronously.

[0067] As shown in Figure 1 , the filter bottle 11 is provided with a third guide rail 15 for providing a guiding action for the second driving member 141, the second driving member 141 is in sliding cooperation with the third guide rail 15, and the guiding direction of the third guide rail 15 is parallel to the first direction.

[0068] Specifically, in some embodiments, as shown in Figure 1As shown, the second moving member 142 can slide relative to the filter bottle 11 to an end of the filter element 12 supported in the accommodating space 116, and the part of the second moving member 142 can position the water outlet pipe 121 of the filter element 12.

[0069] The second moving member 142 not only can support the filter element 12 and lift the filter element 12, but also can position the water outlet pipe 121, so that the water outlet pipe 121 can be accurately inserted into the corresponding water outlet 113 of the filter bottle 11.

[0070] Specifically, the second moving member 142 can position the water outlet pipe 121 in the form of clamping, that is, the second moving member 142 clamps the water outlet pipe 121, which can ensure that the water outlet pipe 121 can be inserted into the corresponding water outlet 113 and can also ensure that the water outlet pipe 121 can be accurately pulled out when the filter element 12 is disassembled.

[0071] As shown in the drawings, Figure 1 In some embodiments, the water purifying device 10 includes two force applying assemblies 14 and two lifting assemblies 13, and the lifting assemblies 13 correspond to the force applying assemblies 14 one by one. The two force applying assemblies 14 are arranged on the two sides of the filter element 12.

[0072] The two second moving members 142 are respectively located on the opposite sides of the water outlet pipe 121 of the filter element 12, and the two second driving members 141 can drive the two second moving members 142 to move towards each other to clamp the water outlet pipe 121.

[0073] When the second moving member 142 takes out the filter element 12 from the filter bottle 11, the second moving member 142 is switched to a released state, and the filter element 12 can be taken out.

[0074] The ends of the two second moving members 142 close to each other can be provided with an embedded clamp for clamping the water outlet pipe.

[0075] As shown in the drawings, Figure 1 In some embodiments, the filter bottle 11 includes a bottle body 112 and a bottle cap 111, and the bottle cap 111 is openably installed at the opening of the bottle body 112. When the filter element 12 needs to be disassembled, the bottle cap 111 is opened. The first direction is a direction along the depth direction of the bottle body 112 close to the bottle cap 111. The bottom of the bottle body 112 is provided with a water outlet 113 matched with the water outlet pipe 121.

[0076] As shown in the drawings, Figure 5 In some embodiments, the wall surface of the filter bottle 11 provided with the second driving member 141 is a first wall surface 114, and the first wall surface 114 is parallel to the lifting direction of the lifting assembly 13 and the second direction.

[0077] The wall surface on which the lifting assembly 13 is installed on the filter bottle 11 is the second wall surface 115, and the second wall surface 115 is perpendicular to the second direction.

[0078] Specifically, such as Figure 5 As shown, in one embodiment, the second driving member 141 is slidably disposed on the first wall surface 114, and the sliding direction is parallel to the first direction. When the second driving member 141 includes a second motor, the rotation axis of the second motor is perpendicular to the first wall surface 114.

[0079] The first driving member 131 is disposed on the second wall surface 115. When the first driving member 131 includes a first motor, the rotation shaft of the first motor is perpendicular to the second wall surface 115.

[0080] Furthermore, in some embodiments, such as Figure 4 As shown, the second moving part 142 is provided with a first guide rail 16, and the guiding direction of the first guide rail 16 is the second direction;

[0081] The filter bottle 11 is provided with a second guide rail 17, and the guiding direction of the second guide rail 17 is parallel to the first direction;

[0082] The water purification device 10 also includes a roller 18, one end of which is slidably engaged with the first guide rail 16, and the other end of which is slidably engaged with the second guide rail 17.

[0083] When the second moving part 142 slides relative to the filter bottle 11 in the second direction, the roller 18 slides in the first guide rail 16, and both the second guide rail 17 and the roller 18 remain stationary relative to the filter bottle 11.

[0084] When the second moving part 142 rises and falls with the moving part, the roller 18 slides in the second guide rail 17, and the first guide rail 16 rises and falls synchronously with the roller 18.

[0085] The second guide rail 17 is fixed relative to the filter bottle 11. The roller 18 can only slide relative to the filter bottle 11 in the guiding direction of the second guide rail 17. The roller 18 is fixed in relative position to the filter bottle 11 in the second direction, while the roller 18 can slide relative to the first guide rail 16. Therefore, the roller 18 will not obstruct the second moving part 142 from sliding relative to the filter bottle 11.

[0086] The second guide rail 17 provides guidance for the lifting and lowering process of the second moving part 142, making the lifting and lowering of the second moving part 142 more stable. Of course, there can be multiple combinations of the second guide rail 17, the first guide rail 16 and the roller 18 in the water purification device 10, and no specific restrictions are made here.
