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. A water purifier generally includes a filter element assembly, a handle and a housing assembly. The filter element assembly is inserted into the housing assembly. The handle is rotatably connected to the filter element assembly, and one end of the handle abuts against the housing assembly during the rotation of the handle, and the filter element assembly is taken out of the housing assembly and decorated in the housing assembly by using the lever principle.

[0003] However, when the traditional water purifier is in use, the filter element assembly still has the problem of unstable installation, which affects the use of the water purifier. Summary of the Invention

[0004] Based on this, in view of the problem that when the traditional water purifier is in use, the filter element assembly still has the problem of unstable installation, which affects the use of the water purifier, a purification structure and a water purifier are proposed. When the purification structure and the water purifier are in use, the filter element assembly can be stably installed.

[0005] The specific technical solutions are as follows:

[0006] 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 application end which are oppositely arranged; the handle is rotatably connected to the filter element assembly; the housing assembly is provided with an installation cavity for installing the filter element assembly, and the housing assembly is further provided with a pressure-bearing part. The housing assembly or the filter element assembly is provided with a locking part; when the handle rotates in the first direction, the abutting end abuts against the pressure-bearing part, and the handle drives the filter element assembly to move relative to the installation cavity so that the filter element assembly is locked and cooperated with the housing assembly and fixed in the installation cavity; when the filter element assembly is locked and cooperated with the housing assembly, the force application end is locked and cooperated with the locking part.

[0007] The technical solutions are further described below:

[0008] In one embodiment, the locking part includes a first clamping part, and the force application end is provided with a second clamping part for clamping and cooperating with the first clamping part.

[0009] In one embodiment, the first clamping part is a buckle, and the second clamping part is a clamping groove. The force application end is clamped and cooperated with the buckle through the clamping groove to be locked and cooperated with the locking part.

[0010] In one embodiment, the buckle includes a first elastic member and a convex, the convex is connected to the filter element assembly through the first elastic member, and the convex is movable relative to the filter element assembly. The convex extends into or exits the card slot by pressing the first elastic member, so that the convex can be switched between being engaged with the card slot and being separated from the card slot.

[0011] In one embodiment, the buckle further includes a button and a second elastic member. The convex is provided with a mounting hole penetrating through the side wall of the convex, and 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, and the other end of the second elastic member is connected to the button. The button presses the second elastic member and moves along the extending direction of the pressing inclined surface to drive the first elastic member to drive the convex to exit the card slot.

[0012] In one embodiment, the abutting end is provided with a first abutting portion and a second abutting portion, and an insertion gap for inserting the pressure-bearing portion is formed between the first abutting portion and the second abutting portion, and the insertion gap is in clearance fit with the pressure-bearing portion;

[0013] When the handle rotates in the first direction, the first abutting portion abuts against the pressure-bearing portion, and the handle drives the filter element assembly to move relative to the installation cavity until the filter element assembly is locked and fixed in the installation cavity with the housing assembly;

[0014] When the handle rotates in the second direction, the second abutting portion abuts against the pressure-bearing portion, and the handle drives the filter element assembly to move relative to the installation cavity until the locking between the filter element assembly and the housing assembly is disconnected and they can be separated.

[0015] In one embodiment, the first abutting portion is provided with a first abutting surface, the second abutting portion is provided with a second abutting surface, and the first abutting surface and the second abutting surface are spaced apart to form the insertion gap;

[0016] When the handle rotates in the first direction, the first abutting surface abuts against the pressure-bearing portion;

[0017] When the handle rotates in the second direction, the second abutting surface abuts against the pressure-bearing portion.

[0018] 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.

[0019] In one embodiment, the pressure-bearing portion 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 force driving the filter element assembly to move in a direction away from the installation cavity, the third abutting surface applies a force to the first abutting surface driving the handle to rotate in a first direction.

[0020] 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.

[0021] In one embodiment, the handle is further provided with a connecting portion, which is arranged between the abutting end and the force-applying end, and the second abutting surface is an arc-shaped abutting surface. When the handle rotates along the second direction, the distance from the point where the arc-shaped abutting surface abuts the pressure-bearing portion to the connecting portion gradually increases.

[0022] On the other hand, the present application also relates to a water purifier, comprising the purification structure in any of the above embodiments.

[0023] When the purification structure and the water purifier are in use, the handle is driven to rotate in the first direction, and the handle drives the filter element assembly to move relative to the installation cavity so that the filter element assembly is locked and matched with the housing assembly and fixed in the installation cavity; further, when the housing assembly is locked and matched with the filter element assembly, the force-applying end is locked and matched with the locking portion to restrict the handle from continuing to rotate, thereby further locking the filter element assembly. In addition, locking the handle with the locking portion can prevent the handle from being misoperated, causing the handle to drive the filter element assembly out of the installation cavity.

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0047] Please refer to Figure 1, in a purification structure 10 of an embodiment, it 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, and a filter medium is installed in the filter bottle body 210. 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 medium or clean the filter medium, 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.

[0048] Specifically, please refer to Figure 2 and Figure 3 , in one of the embodiments, 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, the installation portion 212 is fixedly arranged on the filter bottle body 210, and the connecting portion 130 is rotatably connected to the installation portion 212.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Based on the above embodiments, by driving the handle 100 to rotate in the first direction, the filter bottle body 210 can 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.

[0053] 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 fix the filter bottle body 210 in the installation cavity 312 or drive the filter bottle body 210 to separate from the installation cavity 312.

[0054] 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, the longitudinal section passing through the center line of the filter bottle body 210 is used as the first reference plane A, and the longitudinal section passing through the connection between the installation part 212 and the filter bottle body 210 and parallel to the first reference plane A is used as the second reference plane B. 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. Therefore, on the premise of the same power arm ( Figure 2 a2 in), this "lever" structure is a labor-saving lever, and thus it can drive the filter bottle body 210 to separate from the installation cavity 312 more labor-savingly.

[0055] When the filter element assembly 200 is assembled with the housing assembly 300, the water channels in the filter element assembly 200 need to be docked with the water channels of the housing assembly 300 to ensure smooth water flow. Please refer to Figure 1 , in one embodiment, the housing assembly 300 is provided with a first water channel part 322, and the first water channel part 322 is provided with a first open end 3222; the filter element assembly 200 is provided with a second water channel part 222, and the second water channel part 222 is fixedly arranged on the filter bottle body 210. The second water channel 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 to the housing assembly 300. Optionally, the second water channel part 222 can be a water channel adapter.

[0056] Please refer to 1 and Figure 3 , during the assembly of the filter bottle body 210, the driving handle 100 is rotated in the first direction, the abutting end 110 abuts against the bearing part 324, and the 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 to the housing assembly 300 through the locking cooperation of the first open end 3222 and 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, the sealing ring can be in interference fit with the corresponding side wall for fixation.

[0057] 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 in the second direction, the abutting end 110 abuts against the 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 channel part 322 and the second water channel part 222 are disengaged under force, thereby disconnecting 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.

[0058] Please refer to Figure 1 , as an optional structure of the housing assembly 300, in one embodiment, the housing assembly 300 includes a water channel member 320 and an installation housing 310. The installation housing 310 is provided with an installation cavity 312. The water channel member 320 is fixedly arranged on the outer wall of the installation housing 310 and is arranged outside the installation cavity 312. The water channel member 320 is provided with a first water channel part 322 and a bearing part 324. Both the first open end 3222 and the second open end 2222 are arranged outside the installation cavity 312.

[0059] 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 is disposed at the open end of the filter bottle body 210. The end cap 220 is provided with a second water passage portion 222. The second open end 2222 of the second water passage portion 222 is disposed outside the installation cavity 312. During installation, first insert the filter bottle body 210 into the installation 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.

[0060] The alternative structures of the handle 100 will be described below in conjunction with the embodiments.

[0061] 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 and the insertion gap 116 are in clearance fit. 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.

[0062] 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 of 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.

[0063] Please refer to Figure 3 、 Figure 4 and Figure 7 , When the filter bottle body 210 needs to be installed, the handle 100 rotates in the first direction. The first abutting portion 112 abuts against the pressure-bearing portion 324. At this time, the pressure-bearing portion 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 within 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 open end 3222 and the second open end 2222 are docked until the first open end 3222 and the second open end 2222 are locked to achieve the detachable connection between the filter bottle body 210 and the housing assembly 300.

[0064] Please refer to Figure 5 、 Figure 6 and Figure 7When the filter bottle body 210 needs to be taken out, the handle 100 rotates in the second direction. At this time, the second abutting portion 114 abuts against the pressure-bearing portion 324. At this time, the force-applying end 120 is forced to continue to drive the filter bottle body 210 to move in the direction away from the installation cavity 312. At this time, since the handle 100 is connected to the filter bottle body 210, when the force-applying end 120 continues to rotate, under the support of the second abutting portion 114 and the pressure-bearing portion 324, the filter bottle body 210 has a certain displacement relative to the installation cavity 312 until the filter bottle body 210 and the housing assembly 300 are disconnected and can be separated. Specifically, when the filter bottle body 210 moves relative to the installation cavity 312, the first open end 3222 and the second open end 2222 gradually loosen until they are disconnected and can be separated.

[0065] Optionally, see Figure 2 , Figure 4 and Figure 7 The first abutting portion 112 is provided with a first abutting surface 1122, and the second abutting portion 114 is provided with a second abutting surface 1142. The first abutting surface 1122 and the second abutting surface 1142 are spaced apart to form an insertion gap 116; when the handle 100 rotates along the first direction, the first abutting surface 1122 abuts against the pressure-bearing portion 324; when the handle 100 rotates along the second direction, the second abutting surface 1142 abuts against the pressure-bearing portion 324.

[0066] Please refer to Figure 4 and Figure 8 The first opening end 3222 of the first water channel portion 322 faces upward (in the direction of pushing open the filter bottle body 210), and the second opening end 2222 of the second water channel portion 222 faces downward (in the direction of inserting the filter bottle body 210). The first opening end 3222 and the second opening end 2222 are connected and connected. When the water flows along the first opening end 3222 to the second opening end 2222, the water will exert a certain impact force on the second opening end 2222, and the impact force may cause the filter bottle body 210 to be pushed out of the installation cavity 312. Based on this, please refer to Figure 4 and Figure 8 In this embodiment, the pressure-bearing portion 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 force F3 driving the filter element assembly 200 to move in a direction away from the installation cavity 312, the third abutting surface 3242 exerts a second force F4 on the first abutting surface driving the handle 100 to rotate in the first direction (see Figure 8 At this time, when facing the impact of water flow on the second opening end 2222, the third abutting surface 3242 will exert a second force on the first abutting surface 1122 as a reaction force, and the reaction force causes the handle 100 to rotate along the first direction, thereby achieving a "self-locking" effect, thereby improving the stability of the filter bottle body 210 installed in the installation cavity 312.

[0067] 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. Thus, 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 by the Figure 8 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 faces the side of 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.

[0068] 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.

[0069] 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 during the whole 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 shown in 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 the resistance arm is reduced at this time; 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 the resistance arm is increased at this time. 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 sudden increase or decrease. In addition, during the whole process of taking out the filter bottle body 210, the experience is also better.

[0070] 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 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.

[0071] Specifically, the locking part 230 includes a first clamping part, and the force application end 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, and the disassembly and assembly are convenient.

[0072] Optionally, please refer to Figures 10 to 12 , the first clamping part is a buckle, the second clamping part is a clamping groove 140, and the force application end 120 is locked and cooperated with the locking part 230 through the clamping groove 140 and 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.

[0073] 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 exits 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 a chute or guide rail for sliding cooperation with the convex lug 234 can be provided on the end cap 220.

[0074] 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.

[0075] 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 exit the card slot 140. Please refer to Figure 11 , the setting principle of the inclination mode of the pressing inclined surface 2342 is: 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 exit 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.

[0076] Furthermore, 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 compared to when the installation part 212 is disposed at the first reference plane A. Further, when the filter element assembly 200 is subjected to a first acting force F3 that drives the filter element assembly 200 to move in a direction away from the installation cavity 312, on the premise that the magnitude of the first acting force remains unchanged, the acting force exerted by the locking part 230 on the handle 100 to lock the handle 100 is relatively small. 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 subjected to an impact force.

[0077] Based on any of the above embodiments, please refer to Figure 13 and Figure 14 , the outer wall of the filter bottle body 210 is provided with a first limiting protrusion 214, and the inner wall of the installation cavity 312 is provided with a first limiting groove 3122 that engages with the first limiting protrusion 214 in a concave-convex manner. 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 engagement 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, the outer wall of the filter bottle body 210 may further be provided with a second limiting groove, and the inner wall of the installation cavity 312 is provided with a second limiting protrusion that engages with the second limiting groove in a concave-convex manner. The function achieved is the same as that of the foregoing embodiment, and will not be elaborated here one by one.

[0078] Furthermore, 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.

[0079] On the other hand, the present application also relates to a water purifier, including the purification structure 10 in any of the above embodiments.

[0080] When the above water purifier is in use, by driving the handle 100 to rotate in the first direction, the handle 100 drives the filter element assembly 200 to move relative to the installation cavity 312 so that the filter element assembly 200 is locked and fitted with the housing assembly 300 and fixed in the installation cavity 312; further, when the housing assembly 300 is locked and fitted with the filter element assembly 200, the force application end 120 is locked and fitted with the locking portion 230 to limit the continuous rotation of the handle 100, thereby further locking the filter element assembly 200. In addition, locking the handle 100 with the locking portion 230 can prevent the handle 100 from misoperating and causing the handle 100 to drive the filter element assembly 200 to disengage from the installation cavity 312.
