Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and particularly to a purification structure and a water purifier. Background Art

[0002] With the improvement of living standards, people pay more and more attention to the quality of life and health. The health problem of household drinking water has long been the focus of social attention. Therefore, people often choose water purifiers to purify household water to improve the water quality. The service life of the filter element in the water purifier is limited, and the filter element needs to be replaced after the water purifier has been used for a long time. However, it is more laborious to replace the filter element in the traditional water purifier, which affects the efficiency of filter element replacement. Summary of the Invention

[0003] Based on this, in view of the problem that it is more laborious to replace the filter element in the traditional water purifier, which affects the efficiency of filter element replacement, a purification structure and a water purifier are proposed. When the purification structure and the water purifier are in use, the filter element can be replaced more labor-savingly, and the replacement efficiency of the filter element is improved.

[0004] The specific technical solutions are as follows:

[0005] On the one hand, the present application relates to a purification structure, including a handle, a filter element assembly and a housing assembly. The handle includes an abutting end and a force-applying end which are oppositely arranged, and a connecting portion arranged between the abutting end and the force-applying end; the filter element assembly includes a filter bottle body and a mounting portion, the mounting portion is fixedly arranged on the side wall of the filter bottle body, and the mounting portion is rotationally connected with the connecting portion; the housing assembly is provided with a mounting cavity for installing the filter bottle body, and the housing assembly is further provided with a pressure-bearing portion. When the force-applying end is forced to rotate, the abutting end abuts against the pressure-bearing portion, and the handle drives the filter bottle body to move relative to the mounting cavity so that the filter bottle body is detachably connected with the housing assembly or the filter bottle body is disconnected from the housing assembly; wherein, taking the longitudinal section passing through the center line of the filter bottle body as the first reference plane, and taking the longitudinal section passing through the connection portion of the mounting portion and the filter bottle body and parallel to the first reference plane as the second reference plane, the vertical distance between the pressure-bearing portion and the first reference plane is greater than the vertical distance between the pressure-bearing portion and the second reference plane.

[0006] The technical solutions are further described below:

[0007] In one embodiment, when the handle rotates in the first direction, the abutting end abuts against the pressure-bearing portion, and the handle drives the filter bottle body to move relative to the mounting cavity until the filter bottle body is detachably connected with the housing assembly and is fixedly arranged in the mounting cavity;

[0008] When the handle rotates in the second direction, the abutting end abuts against the pressure-bearing part, the force-applying end rotates in the direction of loosening the filter bottle body, and the handle drives the filter bottle body to move relative to the installation cavity until the filter bottle body is disconnected from the housing assembly and can be separated.

[0009] In one embodiment, the housing assembly is provided with a first waterway part, and the first waterway part is provided with a first open end; the filter element assembly is provided with a second waterway part, the second waterway part is fixedly arranged on the filter bottle body, and the second waterway part is provided with a second open end;

[0010] When the handle rotates in the first direction, the abutting end abuts against the pressure-bearing part, and the handle drives the filter bottle body to move relative to the installation cavity until the first open end and the second open end are butted and communicated and locked in cooperation, and the filter element assembly is detachably connected to the housing assembly through the locking cooperation of the first open end and the second open end;

[0011] When the handle rotates in the second direction, the abutting end abuts against the pressure-bearing part, and the force-applying end rotates in the direction of loosening the filter bottle body until the first waterway part and the second waterway part are separated under force.

[0012] In one embodiment, the housing assembly includes a waterway member and an installation housing, the installation housing is provided with the installation cavity, the waterway member is fixedly arranged on the installation housing and is arranged outside the installation cavity, the waterway member is provided with the first waterway part and the pressure-bearing part, and the first open end is arranged outside the installation cavity.

[0013] In one embodiment, the abutting end is provided with a first abutting part and a second abutting part, an insertion gap for inserting the pressure-bearing part is formed between the first abutting part and the second abutting part, and the insertion gap is in clearance fit with the pressure-bearing part;

[0014] When the handle rotates in the first direction, the first abutting part abuts against the pressure-bearing part, and the handle drives the filter bottle body to move relative to the installation cavity until the filter bottle body is detachably connected to the housing assembly and is fixedly arranged in the installation cavity;

[0015] When the handle rotates in the second direction, the second abutting part abuts against the pressure-bearing part, the force-applying end rotates in the direction of loosening the filter bottle body, and the handle drives the filter bottle body to move relative to the installation cavity until the filter bottle body is disconnected from the housing assembly and can be separated.

[0016] In one embodiment, the first abutting part is provided with a first abutting surface, the second abutting part is provided with a second abutting surface, and the first abutting surface and the second abutting surface are arranged at intervals to form the insertion gap;

[0017] When the handle rotates in the first direction, the first abutting surface abuts against the pressure-bearing part;

[0018] When the handle rotates in the second direction, the second abutting surface abuts against the pressure-bearing part.

[0019] In one embodiment, the pressure-bearing part is provided with a third abutting surface for abutting and cooperating with the first abutting surface. When the filter element assembly is subjected to a first acting force that drives the filter element assembly to move in a direction away from the installation cavity, the third abutting surface exerts a second acting force on the first abutting surface to drive the handle to rotate in the first direction.

[0020] In one embodiment, the third abutting surface is a first abutting inclined surface, the first abutting inclined surface faces the bottom wall of the installation cavity, and the height of the first abutting inclined surface from the bottom wall of the installation cavity gradually decreases along the direction close to the central axis of the installation cavity.

[0021] In one embodiment, the first abutting surface is a second abutting inclined surface, and the inclination trend of the second abutting inclined surface is adapted to the inclination trend of the first abutting inclined surface so as to be able to fit with the first abutting inclined surface.

[0022] In one embodiment, the second abutting surface is an arc-shaped abutting surface. When the handle rotates in the second direction, the distance from the point where the arc-shaped abutting surface abuts against the pressure-bearing part to the connecting part gradually increases.

[0023] In one embodiment, the filter element assembly or the housing assembly is provided with a locking part. When the handle rotates in the first direction, the abutting end abuts against the pressure-bearing part. When the handle drives the filter bottle body to move relative to the installation cavity until the filter bottle body is detachably connected to the housing assembly, the force-applying end is locked and cooperated with the locking part.

[0024] In one embodiment, the locking part includes a first clamping part, and the force-applying end is provided with a second clamping part for clamping and cooperating with the first clamping part.

[0025] In one embodiment, the force-applying end is provided with a clamping groove, the locking part is a clamping buckle, and the force-applying end is clamped and cooperated with the clamping buckle through the clamping groove to be locked and cooperated with the locking part.

[0026] In one embodiment, the clamping buckle includes a first elastic member and a clamping protrusion. The clamping protrusion is connected to the filter element assembly through the first elastic member, and the clamping protrusion can move relative to the filter element assembly. The clamping protrusion extends into or out of the clamping groove by squeezing the first elastic member under force to switch between being clamped and cooperated with the clamping groove and being separated from the clamping groove.

[0027] In one embodiment, the buckle further includes a button and a second elastic member. The convex has a mounting hole penetrating through the side wall of the convex. A pressing inclined surface is formed on the inner wall of the mounting hole. One end of the second elastic member passes through the mounting hole and is connected to the filter element assembly. The other end of the second elastic member is connected to the button. When the button is stressed to squeeze the second elastic member and move along the extending direction of the pressing inclined surface, the first elastic member is driven to drive the convex to protrude out of the clamping groove.

[0028] On the other hand, the present application also relates to a water purifier including the purification structure in any of the above embodiments.

[0029] In the purification structure, the filter medium is generally arranged in the filter bottle body. When the filter bottle body is installed, it is first inserted into the installation cavity. By applying an external force to the force application end, the force application end drives the abutting end to rotate to abut against the pressure bearing part. When the force application end continues to be stressed and rotates, the handle drives the filter bottle body to move relative to the installation cavity so that the filter bottle body is detachably connected to the housing assembly. When the filter medium needs to be replaced, by applying an external force to the force application end, the force application end rotates. At this time, the pressing end abuts against the pressure bearing part. The force application end continues to be stressed and rotates to drive the filter bottle body to move relative to the installation cavity so that the filter bottle body is disconnected from the housing assembly. Then, the filter bottle body can be taken out of the installation cavity to clean or replace the filter medium inside the filter bottle body. Further, since the vertical distance between the pressure bearing part and the first reference plane is greater than the vertical distance between the pressure bearing part and the second reference plane, therefore, the resistance arm formed between the acting point between the pressure bearing part and the abutting end and the installation part is smaller than the resistance arm formed between the acting point between the pressure bearing part and the abutting end and the installation part when the installation part is arranged on the first reference plane. Furthermore, on the premise of the same power arm, the handle can make the filter bottle body separate from the installation cavity more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0053] Please refer to Figure 1, The purification structure 10 in one embodiment includes a handle 100, a filter element assembly 200, and a housing assembly 300. The filter element assembly 200 includes a filter bottle body 210 which is provided with filter media. The housing assembly 300 is provided with an installation cavity 312, and the filter bottle body 210 is detachably installed in the installation cavity 312. When it is necessary to replace the filter media or clean the filter media, the filter bottle body 210 can be taken out of the installation cavity 312 through the handle 100. Optionally, the way that the filter bottle body 210 is detachably installed in the installation cavity 312 can be: the filter bottle body 210 is detachably connected to the inner wall of the installation cavity 312; or, the filter bottle body 210 is detachably connected to a component outside the installation cavity 312. When it is necessary to drive the filter bottle body 210 to disengage from the installation cavity 312, it is necessary to drive the filter bottle body 210 to disconnect from this component.

[0054] Specifically, please refer to Figure 2 and Figure 3 , In one embodiment, the handle 100 includes an abutting end 110 and a force - applying end 120 which are oppositely arranged, and a connecting portion 130 arranged between the abutting end 110 and the force - applying end 120. The filter element assembly 200 further includes an installation portion 212 which is fixedly arranged on the filter bottle body 210, and the connecting portion 130 is rotatably connected to the installation portion 212.

[0055] Please refer to Figure 3 and Figure 4 , The housing assembly 300 is further provided with a pressure - bearing portion 324. When the handle 100 rotates in the first direction, the abutting end 110 abuts against the pressure - bearing portion 324, and the handle 100 and the pressure - bearing portion 324 form a lever structure with the pressure - bearing portion 324 as the "fulcrum". At this time, when the handle 100 rotates, the handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 until the filter bottle body 210 is detachably connected to the housing assembly 300 and fixedly arranged in the installation cavity 312.

[0056] Specifically, during the use process, please continue to refer to Figure 3 and Figure 4 , when the handle 100 rotates in the first direction, the abutting end 110 first abuts against the pressure - bearing portion 324. As the force - applying end 120 continuously receives force, the handle 100 continuously rotates. At this time, the handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 until the filter bottle body 210 is detachably connected to the housing assembly 300 and fixedly arranged in the installation cavity 312. Optionally, the first direction can be the clockwise direction.

[0057] Please refer to Figure 5 , Figure 6 and Figure 9, when the handle 100 rotates in the second direction, the abutting end 110 abuts against the pressure-bearing part 324, and the force-applying end 120 drives the filter bottle body 210 to move in a direction away from the installation cavity 312. The handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 until the filter bottle body 210 is disconnected from the housing assembly 300 and can be separated. Among them, the state where the filter bottle body 210 is disconnected from the housing assembly 300 and can be separated can be: the filter bottle body 210 is still installed in the installation cavity 312, but the filter bottle body 210 and the installation cavity 312 are in a state where they can be separated as long as they want to be separated; or, when the filter bottle body 210 is disconnected from the housing assembly 300, the filter bottle body 210 is directly pulled out of the installation cavity 312. Specifically, the first direction can be the clockwise direction, and the second direction can be the counterclockwise direction.

[0058] Based on the above embodiments, by driving the handle 100 to rotate in the first direction, the filter bottle body 210 can be driven to be fixed in the installation cavity 312 to complete the installation of the filter bottle body 210; by driving the handle 100 to rotate in the second direction, the filter bottle body 210 can be separated from the installation cavity 312 to take out the filter bottle body 210.

[0059] Please refer to Figure 2 , where F1 is the power, F2 is the resistance, a2 is the power arm, and a1 is the resistance arm. In order to make the entire "lever" structure a labor-saving lever, the ratio of the power arm a2 to the resistance arm a1 is K, where K≥2.564. Within this range, it is more labor-saving for the handle 100 to drive the filter bottle body 210 to be fixed in the installation cavity 312 or to drive the filter bottle body 210 to be separated from the installation cavity 312.

[0060] Since a "lever" structure is formed between the handle 100 and the pressure-bearing part 324, in order to make this "lever" structure a labor-saving lever, in one of the embodiments, taking the longitudinal section passing through the center line of the filter bottle body 210 as the first reference plane A, and taking the longitudinal section passing through the connection part of the installation part 212 and the filter bottle body 210 and parallel to the first reference plane A as the second reference plane B, and the second reference plane B is the cross-section of a partial structure of the filter bottle body 210. The vertical distance between the pressure-bearing part 324 and the first reference plane A is greater than the vertical distance between the pressure-bearing part 324 and the second reference plane B. In this way, the resistance arm a1 formed between the acting point (please refer to Figure 2 the C point in) between the pressure-bearing part 324 and the abutting end 110 and the installation part 212 is smaller than the resistance arm a1 formed by the traditional setting of the installation part 212 at the first reference plane A. Thus, with the same power arm ( Figure 2On the premise of a2) in it, the "lever" structure is a labor-saving lever, and thus the filter bottle body 210 can be driven to separate from the installation cavity 312 more labor-savingly. Specifically, the vertical distance from the contact part between the pressure-bearing part 324 and the abutting end 110 to the first reference plane A is greater than the vertical distance from the contact part between the pressure-bearing part 324 and the abutting end 110 to the second reference plane B.

[0061] When the filter element assembly 200 is assembled with the housing assembly 300, it is necessary to dock the water circuit in the filter element assembly 200 with the water circuit of the housing assembly 300 to ensure the smooth conveyance of water flow. Please refer to Figure 1 , in one embodiment, the housing assembly 300 is provided with a first water circuit part 322, and the first water circuit part 322 is provided with a first open end 3222; the filter element assembly 200 is provided with a second water circuit part 222, and the second water circuit part 222 is fixedly arranged on the filter bottle body 210. The second water circuit part 222 is provided with a second open end 2222. During assembly, the filter bottle body 210 is docked and locked with the first open end 3222 through the second open end 2222 to be detachably connected with the housing assembly 300. Optionally, the second water circuit part 222 can be a water circuit adapter.

[0062] Please refer to 1 and Figure 3 , during the assembly of the filter bottle body 210, the driving handle 100 is rotated along the first direction, the abutting end 110 abuts against the pressure-bearing part 324, and the driving handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 until the first open end 3222 and the second open end 2222 are docked and communicated and locked in cooperation. The filter element assembly 200 is detachably connected with the housing assembly 300 by locking and cooperating the first open end 3222 with the second open end 2222. Optionally, a sealing ring can be arranged at the first open end 3222 and / or the second open end 2222. When the first open end 3222 and the second open end 2222 are docked, they can be fixed by the interference fit of the sealing ring with the corresponding side wall.

[0063] Please refer to Figure 1 and Figure 6 , when it is necessary to disassemble the filter bottle body 210, the driving handle 100 is rotated along the second direction, the abutting end 110 abuts against the pressure-bearing part 324, and the force-applying end 120 drives the filter bottle body 210 to move in the direction away from the installation cavity 312 until the first water circuit part 322 and the second water circuit part 222 are disengaged under force, thereby realizing the disconnection of the filter bottle body 210 from the housing assembly 300. At this time, the filter bottle body 210 can be taken out to clean or replace the filter material.

[0064] Please refer to Figure 1, As an alternative structure of the housing assembly 300, in one embodiment, the housing assembly 300 includes a waterway member 320 and a mounting housing 310. The mounting housing 310 is provided with a mounting cavity 312. The waterway member 320 is fixedly arranged on the outer wall of the mounting housing 310 and is disposed outside the mounting cavity 312. The waterway member 320 is provided with a first waterway portion 322 and a pressure-bearing portion 324. Both the first open end 3222 and the second open end 2222 are arranged outside the mounting cavity 312.

[0065] Please refer to Figure 1 , As an alternative structure of the filter element assembly 200, in one embodiment, the filter element assembly 200 further includes an end cap 220. The end cap 220 covers the open end of the filter bottle body 210. The end cap 220 is provided with a second waterway portion 222. The second open end 2222 of the second waterway portion 222 is arranged outside the mounting cavity 312. During installation, first insert the filter bottle body 210 into the mounting cavity 312. At this time, the second open end 2222 is aligned with the first open end 3222, and drive the handle 100 to rotate in the first direction.

[0066] The following will describe the alternative structures of the handle 100 in conjunction with embodiments.

[0067] Please refer to Figure 2 and Figure 7 , In one embodiment, the abutting end 110 is provided with a first abutting portion 112 and a second abutting portion 114. An insertion gap 116 for inserting the pressure-bearing portion 324 is formed between the first abutting portion 112 and the second abutting portion 114. The pressure-bearing portion 324 is in clearance fit with the insertion gap 116. The pressure-bearing portion 324 can be disposed within the insertion gap 116, or during the rotation of the handle 100, the pressure-bearing portion 324 enters the insertion gap 116.

[0068] Please refer to Figure 7 , As one of the alternative structures of the handle 100, in one embodiment, the handle 100 is in a "U" shape, and both sides at the opening of the "U" shape structure are provided with a first abutting portion 112 and a second abutting portion 114. Please refer to Figure 7 , In order to improve the strength, in this embodiment, the side wall of the handle 100 is further provided with a reinforcing rib 150.

[0069] Please refer to Figure 3 , Figure 4 and Figure 7, when it is necessary to install the filter bottle body 210, the handle 100 rotates in the first direction and abuts against the pressure-bearing part 324 through the first abutting part 112. At this time, the pressure-bearing part 324 is equivalent to a support point. The handle 100 continues to rotate and drives the filter bottle body 210 to move relative to the installation cavity 312 until the filter bottle body 210 is detachably connected to the housing assembly 300 and fixed in the installation cavity 312. Specifically, when the handle 100 drives the filter bottle body 210 to continuously move relative to the installation cavity 312, the first opening end 3222 and the second opening end 2222 are butted until the first opening end 3222 and the second opening end 2222 are locked to realize the detachable connection between the filter bottle body 210 and the housing assembly 300.

[0070] Please refer to Figure 5 , Figure 6 and Figure 7 , when it is necessary to take out the filter bottle body 210, the handle 100 rotates in the second direction. At this time, the second abutting part 114 abuts against the pressure-bearing part 324, and the force application end 120 is stressed and continues to drive the filter bottle body 210 to move in the direction away from the installation cavity 312. Since the handle 100 is connected to the filter bottle body 210, when the force application end 120 continues to rotate, under the support of the second abutting part 114 and the pressure-bearing part 324, the filter bottle body 210 has a certain displacement relative to the installation cavity 312 until the connection between the filter bottle body 210 and the housing assembly 300 is disconnected and they can be separated. Specifically, when the filter bottle body 210 moves relative to the installation cavity 312, the first opening end 3222 and the second opening end 2222 are gradually loosened until the connection is disconnected and they can be separated.

[0071] Optionally, please refer to Figure 2 , Figure 4 and Figure 7 , the first abutting part 112 is provided with a first abutting surface 1122, the second abutting part 114 is provided with a second abutting surface 1142, and the first abutting surface 1122 and the second abutting surface 1142 are arranged at intervals to form an insertion gap 116. When the handle 100 rotates in the first direction, the first abutting surface 1122 abuts against the pressure-bearing part 324. When the handle 100 rotates in the second direction, the second abutting surface 1142 abuts against the pressure-bearing part 324.

[0072] Please refer to Figure 4 and Figure 8 , the first opening end 3222 of the first waterway part 322 faces upward (the direction of pushing open the filter bottle body 210), the second opening end 2222 of the second waterway part 222 faces downward (the insertion direction of the filter bottle body 210), and the first opening end 3222 and the second opening end 2222 are butted and communicated. When the water flow rushes from the first opening end 3222 towards the second opening end 2222, the water will exert a certain impact force on the second opening end 2222, and this impact force makes the filter bottle body 210 have the potential risk of being pushed out of the installation cavity 312. Based on this, please refer to Figure 4 andFigure 8 , in this embodiment, the pressure-bearing part 324 is provided with a third abutting surface 3242 for abutting and cooperating with the first abutting surface 1122. When the filter element assembly 200 is subjected to a first acting force that drives the filter element assembly 200 to move in a direction away from the installation cavity 312, the third abutting surface 3242 exerts a second acting force F on the first abutting surface to drive the handle 100 to rotate in the first direction (please refer to Figure 8 the arrow direction). At this time, when facing the impact of the water flow on the second opening end 2222, the second acting force exerted by the third abutting surface 3242 on the first abutting surface 1122 is a reaction force, and this reaction force causes the handle 100 to rotate in the first direction, thereby achieving a "self-locking" effect and enhancing the stability of the filter bottle body 210 installed in the installation cavity 312.

[0073] Optionally, please refer to Figure 8 , the third abutting surface 3242 is a first abutting inclined surface, the first abutting inclined surface faces the bottom wall of the installation cavity 312, and the height of the first abutting inclined surface from the bottom wall of the installation cavity 312 gradually decreases along the direction close to the central axis of the installation cavity 312. In this way, the second acting force exerted by the first abutting inclined surface on the first abutting surface 1122 is perpendicular to the first abutting inclined surface and towards the lower left, as shown in Figure 8 the arrow direction. Under the action of the acting force in this direction, the filter bottle body 210 will be locked. Among them, the first abutting inclined surface facing the bottom wall of the installation cavity 312 means that the first abutting inclined surface is on the side facing the bottom wall of the installation cavity 312, rather than saying that the first abutting inclined surface has to be completely parallel to the bottom wall of the installation cavity 312.

[0074] Furthermore, in order to cooperate with the first abutting inclined surface, please continue to refer to Figure 8 , in this embodiment, the first abutting surface 1122 is a second abutting inclined surface, and the inclination trend of the second abutting inclined surface is adapted to that of the first abutting inclined surface so as to be able to fit with the first abutting inclined surface. Specifically, the orientation of the second abutting inclined surface is exactly opposite to that of the first abutting inclined surface, but the inclination trend is the same.

[0075] When removing the filter bottle body 210, the resistance to be overcome in the early stage of the rotation of the handle 100 is relatively large. When the handle 100 rotates a certain angle, the first opening end 3222 and the second opening end 2222 become loose. At this time, the resistance to be overcome when the handle 100 rotates is relatively small. In order to make the external force required by the handle 100 uniform throughout the process of removing the filter bottle body 210 and avoid sudden changes in the acting force applied to the handle 100, which may easily damage the contact part between the handle 100 and the pressure-bearing part 324 and affect the use of the handle 100. Please refer back to Figure 5, in this embodiment, the second abutting surface 1142 is an arc-shaped abutting surface. When the handle 100 rotates in the second direction, the distance from the point where the arc-shaped abutting surface abuts against the pressure-bearing part 324 to the connecting part 130 gradually increases (as Figure 5 , when the handle 100 rotates in the second direction, the distance gradually changes from h1 to h2). In this way, at the initial stage of rotation, the distance from the point where the arc-shaped abutting surface abuts against the pressure-bearing part 324 to the connecting part 130 is relatively small, and at this time, the resistance arm is reduced; when the first opening end 3222 and the second opening end 2222 become loose, the distance from the point where the arc-shaped abutting surface abuts against the pressure-bearing part 324 to the connecting part 130 is increased, and at this time, the resistance arm is increased. In this way, the force required by the force application end 120 in the early stage of rotation and the force required by the force application end 120 in the middle and late stages of rotation are kept equal or differ little. Furthermore, during the whole process of the handle 100 driving the filter bottle body 210 to be taken out, the external force that needs to be applied to the handle 100 is relatively uniform and there is no situation of being suddenly large or small. In addition, during the whole process of taking out the filter bottle body 210, the experience is also better.

[0076] When the handle 100 drives the filter bottle body 210 to be installed in the installation cavity 312, it is necessary to fix the handle 100 to improve the stability of the filter bottle body 210 installed in the installation cavity 312. Please refer to Figures 10 to 12 , in one of the embodiments, the filter element assembly 200 or the housing assembly 300 is provided with a locking part 230. When the handle 100 rotates in the first direction, the abutting end 110 abuts against the pressure-bearing part 324. When the handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 until the filter bottle body 210 is detachably connected to the housing assembly 300, the force application end 120 is locked and cooperated with the locking part 230. Specifically, in this embodiment, the filter element assembly 200 is provided with a locking part. Specifically, the locking part 230 includes a first clamping part, and the force application end 120 includes a second clamping part that is clamped and cooperated with the first clamping part. In this way, the locking cooperation between the locking part 230 and the force application end 120 is realized through the clamping cooperation of the first clamping part and the second clamping part, so the disassembly and assembly are convenient.

[0077] Optionally, please refer to Figures 10 to 12 , the first clamping part is a buckle, and the second clamping part is a clamping groove 140. The force application end 120 is locked and cooperated with the locking part 230 by the clamping groove 140 being clamped and cooperated with the buckle. During use, the force application end 120 makes the buckle extend into the clamping groove 140 by squeezing the buckle for clamping cooperation.

[0078] Specifically, please refer to Figures 10 to 12, in one embodiment, the buckle includes a first elastic member 232 and a convex lug 234. The convex lug 234 is connected to the filter element assembly 200 through the first elastic member 232. When the handle 100 rotates in the first direction, the force - applying end 120 will squeeze the convex lug 234, causing the convex lug 234 to be stressed and squeeze the first elastic member 232. At this time, the force - applying end 120 continues to rotate until the convex lug 234 faces the card slot 140 and extends into the card slot 140 for snap - fit. When it is necessary to remove the filter bottle body 210, an external force is used to push the convex lug 234 so that the convex lug 234 squeezes the first elastic member 232 and extends out of the card slot 140, thereby realizing the separation of the card slot 140 and the convex lug 234. Specifically, the convex lug 234 is connected to the end cap 220 through the first elastic member 232, and the end cap 220 may be provided with a chute or a guide rail that slidably cooperates with the convex lug 234.

[0079] Optionally, an external force can be applied to the convex lug 234 by pressing the button 236 so that the convex lug 234 can be separated from the card slot 140.

[0080] Specifically, please refer to Figure 11 , the buckle further includes a button 236 and a second elastic member 238. The convex lug 234 is connected to the filter element assembly 200 through the first elastic member 232, and the convex lug 234 is movable relative to the filter element assembly 200. The convex lug 234 is provided with a mounting hole 2344 penetrating the side wall of the convex lug 234. One end of the second elastic member 238 passes through the mounting hole 2344 and is connected to the filter element assembly 200, and the other end of the second elastic member 238 is connected to the button 236. Specifically, the button 236 is connected to the end cap 220 through the second elastic member 238. An inner wall of the mounting hole 2344 forms a pressing inclined surface 2342. When the button 236 is pressed, the button 236 is stressed to squeeze the second elastic member 238 and moves along the extending direction of the pressing inclined surface 2342. At this time, the first elastic member 232 is driven to drive the buckle to extend out of the card slot 140. Please refer to Figure 11 , the setting principle of the inclination mode of the pressing inclined surface 2342 is as follows: when the button 236 squeezes the pressing inclined surface 2342 and moves along the extending direction of the pressing inclined surface 2342, the direction of the force of the button 236 on the pressing inclined surface 2342 is the direction in which the convex lug 234 is stressed to withdraw from the card slot 140, and the height of the pressing inclined surface 2342 gradually decreases along the pressing direction. The orientation of the pressing inclined surface 2342 is towards the side of the convex lug 234. Therefore, when it is necessary to remove the filter bottle body 210, only need to press the button 236 to separate the convex lug 234 from the card slot 140, and then rotate the handle 100 in the second direction.

[0081] Further, since the vertical distance between the pressure-bearing part 324 and the first reference plane A is greater than the vertical distance between the pressure-bearing part 324 and the second reference plane B, therefore, the resistance arm formed between the acting point between the pressure-bearing part 324 and the abutting end 110 and the mounting part 212 is smaller than that when the mounting part 212 is disposed at the first reference plane A. Furthermore, when the filter element assembly 200 is subjected to a first acting force that drives the filter element assembly 200 to move away from the installation cavity 312, on the premise that the magnitude of the first acting force remains unchanged, the locking part 230 applies a relatively smaller acting force to lock the handle 100. In this way, the locking part 230 can "lock" the handle 100 with a smaller force, avoiding the handle 100 from detaching from the locking part 230 when the filter element assembly 200 is impacted.

[0082] Based on any of the above embodiments, please refer to Figure 13 and Figure 14 , a first limiting protrusion 214 is provided on the outer wall of the filter bottle body 210, and a first limiting groove 3122 that is in concave-convex fit with the first limiting protrusion 214 is provided on the inner wall of the installation cavity 312. When the filter bottle body 210 is installed in the installation cavity 312, it is limited and installed in the installation cavity 312 through the concave-convex fit of the first limiting protrusion 214 and the first limiting groove 3122, avoiding the filter bottle body 210 from rotating relative to the installation cavity 312 under the action of an external force, resulting in the fracture of the connection between the first opening end 3222 and the second opening end 2222. In another embodiment, a second limiting groove may further be provided on the outer wall of the filter bottle body 210, and a second limiting protrusion that is in concave-convex fit with the second limiting groove is provided on the inner wall of the installation cavity 312. The function achieved in this way is the same as that of the foregoing embodiment, and will not be elaborated here one by one.

[0083] Further, please refer to Figure 15 , there is an installation gap 3124 between the inner wall of the filter bottle body 210 and the installation cavity 312. In this way, when disassembling the filter bottle body 210, the handle 100 drives the filter bottle body 210 to move upward. At this time, external air enters the installation cavity 312 through the installation gap 3124 to ensure that the internal air pressure in the installation cavity 312 is uniform when disassembling the filter bottle body 210, thereby facilitating the removal of the filter bottle body 210. When installing the filter bottle body 210, the handle 100 drives the filter bottle body 210 to move downward, and the air in the installation cavity 312 is conveyed to the outside through the installation gap 3124, thereby ensuring that the air pressure in the installation cavity 312 is uniform when disassembling the filter bottle body 210, and thus facilitating the installation of the filter bottle body 210.

[0084] On the other hand, the present application also relates to a water purifier, including the purification structure 10 in any of the above embodiments.

[0085] In the purification structure 10, the filter medium is generally arranged inside the filter bottle body 210. When the filter bottle body 210 is installed, it is first inserted into the installation cavity 312. By applying an external force to the force application end 120, the force application end 120 drives the abutting end 110 to rotate so as to abut against the pressure-bearing part 324. When the force application end 120 continuously rotates under force, the handle 100 drives the filter bottle body 210 to move relative to the installation cavity 312 so that the filter bottle body 210 is detachably connected to the housing assembly 300. When it is necessary to replace the filter medium, by applying an external force to the force application end 120, the force application end 120 rotates and at this time the pressing end abuts against the pressure-bearing part 324. The force application end 120 continuously rotates under force and drives the filter bottle body 210 to move relative to the installation cavity 312 so that the filter bottle body 210 is disconnected from the housing assembly 300. Furthermore, the filter bottle body 210 can be taken out of the installation cavity 312 to clean or replace the filter medium inside the filter bottle body 210. Further, since the vertical distance between the pressure-bearing part 324 and the first reference plane A is greater than the vertical distance between the pressure-bearing part 324 and the second reference plane B, therefore, the resistance arm formed between the acting point between the pressure-bearing part 324 and the abutting end 110 and the installation part 212 is smaller than that when the installation part 212 is arranged at the first reference plane A. Furthermore, on the premise of the same power arm, the handle 100 can make the filter bottle body 210 separate from the installation cavity 312 more labor-savingly.
