In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Referring to fig. 1, an embodiment of a purification structure 10 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, the filter bottle body 210 is provided with a filter material, the housing assembly 300 is provided with an installation cavity 312, the filter bottle body 210 is detachably installed in the installation cavity 312, and when the filter material needs to be replaced or cleaned, the filter bottle body 210 is taken out from the installation cavity 312 through the handle 100. Alternatively, the filter bottle body 210 can be detachably mounted in the mounting cavity 312 in the following manner: the filter flask body 210 is detachably connected with the inner wall of the mounting cavity 312; alternatively, the filter cartridge body 210 may be removably coupled to a member external to the mounting cavity 312, and when it is desired to actuate the filter cartridge body 210 out of the mounting cavity 312, the filter cartridge body 210 may be actuated to disconnect from the member.

Specifically, referring to fig. 2 and 3, in one embodiment, the handle 100 includes an abutting end 110 and a force applying end 120, which are oppositely disposed, and a connecting portion 130 disposed between the abutting end 110 and the force applying end 120. The filter element assembly 200 further includes a mounting portion 212, the mounting portion 212 is fixedly disposed on the filter body 210, and the connecting portion 130 is rotatably connected to the mounting portion 212.

Referring to fig. 3 and 4, the housing assembly 300 further includes a pressing portion 324, when the handle 100 rotates along the second direction, the abutting end 110 abuts against the pressing portion 324, the handle 100 and the pressing portion 324 form a lever structure with the pressing portion 324 as a "fulcrum", at this time, when the handle 100 rotates, the handle 100 drives the filter bottle body 210 to move relative to the mounting cavity 312 until the filter bottle body 210 is detachably connected to the housing assembly 300 and is fixedly disposed in the mounting cavity 312.

Specifically, in the using process, please refer to fig. 3 and 4, when the handle 100 rotates along the second direction, the abutting end 110 first abuts against the pressing portion 324, and the handle 100 rotates continuously with the continuous force applied by the force applying end 120, at this time, the handle 100 drives the filter flask body 210 to move relative to the installation cavity 312 until the filter flask body 210 is detachably connected to the housing assembly 300 and is fixedly disposed in the installation cavity 312. Alternatively, the second direction may be a clockwise direction.

Referring to fig. 5, 6 and 9, when the handle 100 rotates in the first direction, the abutting end 110 abuts against the pressure-bearing portion 324, the force-applying end 120 drives the filter bottle body 210 to move in a direction away from the mounting cavity 312, and the handle 100 drives the filter bottle body 210 to move relative to the mounting cavity 312 until the filter bottle body 210 is disconnected from the housing assembly 300 and can be separated. Among them, the disconnected and separable state between the filter bottle body 210 and the housing assembly 300 may be: the filter cartridge body 210 is still mounted in the mounting cavity 312, but the filter cartridge body 210 and the mounting cavity 312 are in a state that they can be separated if they are separated; alternatively, the filter cartridge body 210 may be pulled directly out of the mounting cavity 312 when the filter cartridge body 210 is disconnected from the housing assembly 300. Specifically, the second direction may be a clockwise direction, and the first direction may be a counterclockwise direction.

Based on the above embodiment, the filter bottle body 210 can be driven to be fixedly arranged in the installation cavity 312 by driving the handle 100 to rotate along the second direction, so as to complete the installation of the filter bottle body 210; the filter bottle body 210 can be detached from the mounting cavity 312 by driving the handle 100 to rotate in a first direction, so as to take out the filter bottle body 210.

Referring to fig. 2, wherein F1 is power, F2 is resistance, a2 is power arm, and a1 is resistance arm. In order to enable the whole structure of the 'lever' to be a labor-saving lever, the ratio of the power arm a2 to the resistance arm a1 is K, wherein K is more than or equal to 2.564. Within this range, the handle 100 is more labor-saving when the filter bottle body 210 is fixedly disposed in the mounting cavity 312 or when the filter bottle body 210 is separated from the mounting cavity 312.

In order to form the lever structure between the handle 100 and the bearing portion 324 into a labor-saving lever, in one embodiment, a longitudinal section passing through a center line of the filter bottle body 210 is a first reference plane a, a longitudinal section passing through a connection point of the mounting portion 212 and the filter bottle body 210 and parallel to the first reference plane a is a second reference plane B, and the second reference plane B is a section of a partial structure of the filter bottle body 210. The vertical distance between the pressing portion 324 and the first reference surface a is greater than the vertical distance between the pressing portion 324 and the second reference surface B, so that the resistance arm a1 formed between the action point (please refer to point C in fig. 2) between the pressing portion 324 and the abutting end 110 and the mounting portion 212 is smaller than the resistance arm a1 formed by the conventional mounting portion 212 disposed on the first reference surface a, and therefore, on the premise of the same power arm (a 2 in fig. 2), the "lever" structure is a labor-saving lever, and the filter bottle body 210 and the mounting cavity 312 can be further separated in a labor-saving manner.

When the filter element assembly 200 is assembled with the housing assembly 300, the waterway of the filter element assembly 200 needs to be butted with the waterway of the housing assembly 300 so as to implement smooth delivery of the water flow.

Optionally, the second waterway portion 222 may be a waterway adapter.

Referring to fig. 1 and 3, when the filter bottle body 210 is assembled, the handle 100 is driven to rotate in the second direction, the abutting end 110 abuts against the pressure bearing portion 324, the handle 100 drives the filter bottle body 210 to move relative to the mounting cavity 312 until the first open end 3222 and the second open end 2222 are in abutting communication and locked fit, and the filter element assembly 200 is in locked fit with the first open end 3222 and the second open end 2222 to be detachably connected with the housing assembly 300. Optionally, first open end 3222 and/or second open end 2222 may be provided with a sealing ring, which may be secured by interference fit with the corresponding sidewall when first open end 3222 and second open end 2222 are mated.

Referring to fig. 1 and 6, when the filter bottle body 210 needs to be detached, the driving handle 100 rotates along the first direction, the abutting end 110 abuts against the pressure bearing portion 324, and the force applying end 120 drives the filter bottle body 210 to move along the direction away from the mounting cavity 312 until the first water path portion 322 and the second water path portion 222 are separated by force, so that the filter bottle body 210 is disconnected from the housing assembly 300, and at this time, the filter bottle body 210 can be taken out to clean or replace the filter material.

Referring to fig. 1, as an optional structure of the housing assembly 300, in one embodiment, the housing assembly 300 includes a waterway 320 and a mounting housing 310, the mounting housing 310 has a mounting cavity 312, the waterway 320 is fixedly disposed on an outer wall of the mounting housing 310 and is disposed outside the mounting cavity 312, the waterway 320 has a first waterway portion 322 and a pressure-bearing portion 324, and the first open end 3222 and the second open end 2222 are both disposed outside the mounting cavity 312.

Referring to fig. 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 on an open end of the filter bottle body 210, the end cap 220 is disposed with a second waterway portion 222, a second open end 2222 of the second waterway portion 222 is disposed outside the mounting cavity 312, when mounting, the filter bottle body 210 is inserted into the mounting cavity 312, and at this time, the second open end 2222 is aligned with the first open end 3222, so as to drive the handle 100 to rotate according to the second direction.

Alternative configurations of handle 100 will be described below in conjunction with the embodiments.

Referring to fig. 2 and 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 and clearance-fitting the pressure receiving portion 324 is formed between the first abutting portion 112 and the second abutting portion 114, the pressure receiving portion 324 may be disposed in the insertion gap 116, or the pressure receiving portion 324 enters the insertion gap 116 during the rotation of the handle 100.

Referring to fig. 7, as an alternative structure of the handle 100, in one embodiment, the handle 100 is U-shaped, and a first abutting portion 112 and a second abutting portion 114 are disposed on two sides of an opening of the U-shaped structure. Referring to fig. 7, in order to enhance the strength, in the present embodiment, the sidewall of the handle 100 is further provided with a reinforcing rib 150.

Referring to fig. 3, 4 and 7, when the filter bottle body 210 needs to be installed, the handle 100 rotates along the second direction, and abuts against the pressure-bearing portion 324 through the first abutting portion 112, at this time, the pressure-bearing portion 324 is equivalent to a supporting 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 with the housing assembly 300 and is fixedly arranged in the installation cavity 312; specifically, as the handle 100 drives the filter bottle body 210 to move continuously relative to the mounting cavity 312, the first open end 3222 and the second open end 2222 are engaged until the first open end 3222 and the second open end 2222 are locked to removably couple the filter bottle body 210 to the housing assembly 300.

Referring to fig. 5, 6 and 7, when the filter bottle body 210 needs to be taken out, the handle 100 rotates along the first direction, at this time, the second abutting portion 114 abuts against the pressure-bearing portion 324, and the force-applying end 120 is forced to continue to rotate the mounting cavity 312 of the filter bottle body 210 along the direction of loosening the filter bottle body 210; because the handle 100 is connected to the filter bottle body 210, as the force applying end 120 continues to rotate, the filter bottle body 210 is displaced relative to the mounting cavity 312 by the second abutting portion 114 and the bearing portion 324 until the filter bottle body 210 is disconnected from the housing assembly 300 and can be separated therefrom. Specifically, as the filter bottle body 210 moves relative to the mounting cavity 312, the first and second open ends 3222 and 2222 gradually loosen until disconnected and able to be separated.

Alternatively, referring to fig. 2, 4 and 7, the first abutting portion 112 is provided with a first abutting surface 1122, the second abutting portion 114 is provided with a third abutting surface 1142, and the first abutting surface 1122 and the third abutting surface 1142 are spaced apart to form the insertion gap 116; when the handle 100 is rotated in the second direction, the first contact surface 1122 contacts the pressing portion 324; when the handle 100 is rotated in the first direction, the third contact surface 1142 contacts the pressing portion 324.

Referring to fig. 4 and 8, the first open end 3222 of the first waterway portion 322 faces upward (in a direction of pushing the filter bottle body 210 open), the second open end 2222 of the second waterway portion 222 faces downward (in an insertion direction of the filter bottle body 210), and the first open end 3222 and the second open end 2222 are in butt joint communication. When water flows along the first open end 3222 toward the second open end 2222, the water may exert an impact force on the second open end 2222, which may cause the filter bottle body 210 to be pushed out of the mounting cavity 312; in view of this, referring to fig. 4 and 8, in the present embodiment, the pressure receiving portion 324 is provided with a second abutting surface 3242 for abutting engagement with the first abutting surface 1122, and when the filter element assembly 200 receives a first force F3 for moving the filter element assembly 200 in a direction to separate from the mounting cavity 312, the second abutting surface 3242 applies a second force F4 (refer to an arrow direction of fig. 8) for rotating the handle 100 in the second direction to the first abutting surface. At this time, when the filter flask body 210 is impacted by the water flow, the second abutting surface 3242 applies a second acting force to the first abutting surface 1122 as a reaction force, and the reaction force causes the handle 100 to rotate in the second direction, so as to achieve a "self-locking" effect, thereby improving the stability of the filter flask body 210 installed in the installation cavity 312.

Optionally, referring to fig. 8, the second abutting surface 3242 is a first abutting inclined surface facing the bottom wall of the mounting cavity 312, and the height of the first abutting inclined surface from the bottom wall of the mounting cavity 312 is gradually reduced along the insertion direction of the mounting cavity 312. In this way, the second force applied by the first abutting inclined surface to the first abutting surface 1122 is perpendicular to the first abutting inclined surface and directed downward to the left, as indicated by the arrow in fig. 8. The filter flask body 210 is locked by the action force in this direction. The first abutting inclined surface faces the bottom wall of the mounting cavity 312, which means that the first abutting inclined surface faces the bottom wall of the mounting cavity 312, and the first abutting inclined surface is not completely parallel to the bottom wall of the mounting cavity 312.

Further, in order to cooperate with the first abutting inclined surface, please continue to refer to fig. 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 the inclination trend of the first abutting inclined surface so as to be able to adhere to the first abutting inclined surface. In particular, the orientation of the second abutment ramp is exactly opposite to that of the first abutment ramp, but the inclination trend is the same.

When the filter flask body 210 is taken out, the resistance to be overcome in the earlier stage of rotation of the handle 100 is large, and after the handle 100 rotates by a certain angle, the first open end 3222 and the second open end 2222 are loosened, and 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 in the whole process of taking out the filter flask body 210, the acting force applied to the handle 100 is prevented from being suddenly changed, so that the contact part between the handle 100 and the bearing part 324 is easily damaged, and the use of the handle 100 is influenced. Referring back to fig. 5, in the present embodiment, the third abutting surface 1142 is an arc-shaped abutting surface, and when the handle 100 rotates along the first direction, the distance between the point where the arc-shaped abutting surface abuts against the pressure-bearing portion 324 and the connecting portion 130 gradually increases (as shown in fig. 5, when the handle 100 rotates along the first direction, the distance gradually changes from h1 to h 2). Thus, at the initial stage of rotation, the distance from the point where the arc-shaped abutment surface abuts against the pressure receiving portion 324 to the connecting portion 130 is small, and at this time, the resistance arm is lowered; when first open end 3222 and second open end 2222 are loosened, the distance from the point at which the arcuate abutment surface abuts pressure bearing portion 324 to connecting portion 130 is increased, which increases the resistance arm. Therefore, the force required by the earlier stage force application end 120 and the force required by the middle and later stage force application end 120 are kept equal or slightly different, so that the external force required to be applied to the handle 100 is relatively uniform in the whole process that the handle 100 drives the filter bottle body 210 to be taken out, and the situation of large and small force does not exist. In addition, experience is also better in the whole process of taking out the filter flask body 210.

When the handle 100 drives the filter bottle body 210 to be installed in the installation cavity 312, the handle 100 needs to be fixed, so as to improve the stability of the filter bottle body 210 installed in the installation cavity 312. Referring to fig. 10-12, in one embodiment, the filter element assembly 200 includes a locking portion 230, wherein when the handle 100 is rotated in the second direction, the abutment end 110 abuts the abutment portion 324, and the handle 100 drives the filter body 210 to move relative to the mounting cavity 312 until the filter body 210 is detachably connected to the housing assembly 300, and the force application end 120 is in locking engagement with the locking portion 230.

Optionally, referring to fig. 10 to 12, the locking portion 230 is a snap, the force applying end 120 is provided with a slot 140, and the force applying end 120 is in snap fit with the snap through the slot 140 to be in locking fit with the locking portion 230. In use, the force application end 120 causes the clip to extend into the catch 140 for a snap fit by squeezing the clip.

Specifically, referring to fig. 10 to 12, in one embodiment, the clip includes a first elastic member 232 and a clip projection 234, and the clip projection 234 is connected to the filter element assembly 200 through the first elastic member 232; when the handle 100 rotates along the second direction, the force application end 120 will press the locking protrusion 234, so that the locking protrusion 234 is forced and presses the first elastic member 232, and at this time, the force application end 120 continues to rotate until the locking protrusion 234 faces the locking groove 140 and extends into the locking groove 140 for locking; when the filter flask body 210 needs to be taken out, the blocking protrusion 234 is pushed by external force, so that the blocking protrusion 234 extrudes the first elastic member 232 and extends out of the blocking groove 140, and the blocking groove 140 is separated from the blocking protrusion 234. Specifically, the locking protrusion 234 is connected to the end cap 220 through the first elastic member 232, and the end cap 220 may be provided with a sliding slot or a guide rail slidably engaged with the locking protrusion 234.

Alternatively, the snap projection 234 may be disengaged from the snap slot 140 by applying a force to the snap projection 234 by depressing the button 236.

Specifically, referring to fig. 11, the clip further includes a button 236 and a second elastic member 238, the locking protrusion 234 is connected to the filter element assembly 200 through the first elastic member 232, and the locking protrusion 234 is movable relative to the filter element assembly 200, the locking protrusion 234 is provided with a mounting hole 2344 penetrating through a side wall of the locking protrusion 234, one end of the second elastic member 238 passes through the mounting hole 2344 to be 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 via a second resilient member 238; the inner wall of the mounting hole 2344 is formed with a pressing inclined surface 2342, when the button 236 is pressed, the button 236 is forced to press the second elastic member 238 and moves along the extending direction of the pressing inclined surface 2342, and at this time, the first elastic member 232 is driven to drive the buckle to extend out of the slot 140. Referring to fig. 11, the pressing slope 2342 is set in a slope manner according to the following principle: when the button 236 presses the pressing slope 2342 and moves in the extending direction of the pressing slope 2342, the force applied to the pressing slope 2342 by the button 236 is in a direction such that the latching protrusion 234 is forced to exit the latching groove 140, and the height of the pressing slope 2342 is gradually reduced in the pressing direction. The pressing slope 2342 is oriented toward the side of the snap projection 234. Therefore, when the filter flask body 210 needs to be taken out, the button 236 is pressed to separate the locking protrusion 234 from the locking groove 140, and then the handle 100 is rotated along the first direction.

Further, since the vertical distance between the bearing portion 324 and the first reference surface a is greater than the vertical distance between the bearing portion 324 and the second reference surface B, the resistance arm formed between the acting point between the bearing portion 324 and the abutting end 110 and the mounting portion 212 is smaller than that formed at the first reference surface a by the mounting portion 212, and further, when the filter element assembly 200 is subjected to the first acting force for driving the filter element assembly 200 to move in the direction away from the mounting cavity 312, the acting force applied to the handle 100 by the locking portion 230 is relatively smaller under the premise that the magnitude of the first acting force is not changed, so that the handle 100 can be "locked" by the locking portion 230 with smaller force, and the handle 100 is prevented from being separated from the locking portion 230 when the filter element assembly 200 is subjected to an impact force.

On the basis of any of the above embodiments, referring to fig. 13 and 14, the outer wall of the filter bottle body 210 is provided with the first limiting protrusion 214, the inner wall of the mounting cavity 312 is provided with the first limiting groove 3122 in concave-convex fit with the first limiting protrusion 214, when the filter bottle body 210 is mounted in the mounting cavity 312, the filter bottle body 210 is mounted in the mounting cavity 312 in a limiting manner through concave-convex fit of the first limiting protrusion 214 and the first limiting groove 3122, so as to prevent the filter bottle body 210 from rotating relative to the mounting cavity 312 under the action of external force, and thus the joint between the first open end 3222 and the second open end 2222 is broken. In another embodiment, the outer wall of the filter flask body 210 may further be provided with a second limiting groove, and the inner wall of the mounting cavity 312 is provided with a second limiting protrusion in concave-convex fit with the second limiting groove, so that the functions of the second limiting groove are the same as those of the previous embodiments, which are not repeated herein.

Further, referring to fig. 15, a mounting gap 3124 exists between the filter bottle body 210 and the inner wall of the mounting cavity 312, so that when the filter bottle body 210 is disassembled, the handle 100 drives the filter bottle body 210 to move upward, and at this time, the external air enters the mounting cavity 312 from the mounting gap 3124 to ensure that when the filter bottle body 210 is disassembled, the internal air pressure in the mounting cavity 312 is uniform, thereby facilitating the disassembly of the filter bottle body 210. When the filter bottle body 210 is installed, the handle 100 drives the filter bottle body 210 to move downwards, the air in the installation cavity 312 is conveyed to the outside through the installation gap 3124, and then the air pressure in the installation cavity 312 is uniform when the filter bottle body 210 is detached, and the filter bottle body 210 is convenient to install.

Because the filter element assembly 200 and the housing assembly 300 are connected through a waterway structure, the connection is relatively tight, and certain difficulty often exists when the filter element assembly 200 is taken out. Based on this, referring to fig. 16, in the present embodiment, the housing assembly 300 further includes a pressure-bearing portion 324 and a lifting portion 326 connected to the pressure-bearing portion 324, wherein a height of the lifting portion 326 relative to the bottom wall of the mounting cavity 312 is higher than a height of the pressure-bearing portion 324 relative to the bottom wall of the mounting cavity 312; when the filter element assembly 200 is required to be separated from the installation cavity 312 to take out the filter element assembly 200, the handle 100 is only required to be driven to rotate by a first angle along the first direction, at this time, the abutting end 110 abuts against the bearing portion 324, the handle 100 drives the filter element assembly 200 to move by a first preset distance relative to the installation cavity 312, when the filter element assembly 200 is firmly installed in the installation cavity 312, the filter element assembly 200 is caused to move by the first preset distance and is not enough to disconnect the filter element assembly 200 from the housing assembly 300, at this time, the handle 100 is driven to continue to rotate by a second angle along the first direction, at this time, the abutting end 110 abuts against the jacking portion 326, because the jacking portion 326 is higher than the bearing portion 324, when the jacking portion 326 abuts against the abutting end 110, the jacking portion 326 can jack the handle 100 by a higher distance, so that the handle 100 can drive the filter element assembly 200 to continue to move by a second preset distance relative to the installation cavity 312, the housing assembly 300 is now disconnected from the filter cartridge assembly 200 and can be separated, thus removing the filter cartridge assembly 200.

Or, in another embodiment, when the handle 100 rotates along the first direction by a third angle, the abutting end 110 abuts against the bearing portion 324, the handle 100 drives the filter element assembly 200 to move relative to the mounting cavity 312 by a third preset distance enough to disconnect and separate the housing assembly 300 from the filter element assembly 200, and then the filter element assembly 200 is driven to move by the rotation of the handle 100, so that the resistance of the filter element assembly 200 to the housing assembly 300 to be disconnected can be overcome more easily by the "lever" principle, and the filter element assembly 200 can be taken out more easily.

Specifically, referring to fig. 16, the pressure-bearing portion 324 includes a pressure-bearing surface 3244, the lifting portion 326 is a lifting protrusion, a height of the lifting protrusion relative to the bottom wall of the mounting cavity 312 is higher than a height of the pressure-bearing surface 3244 relative to the bottom wall of the mounting cavity 312, and the pressure-bearing surface 3244 abuts against the abutting end 110 when the handle 100 is rotated by a first angle in the first direction or when the handle 100 is rotated by a third angle in the first direction. Thus, the abutting end 110 abuts against the bearing surface 3244 first, the handle 100 drives the filter element assembly 200 to move a first distance, at this time, the filter element assembly 200 is not disconnected from the housing assembly 300, when the handle 100 continues to rotate, the abutting end 110 abuts against the jacking protrusion, and the handle 100 drives the filter element assembly 200 to move a second distance, so that the filter element assembly 200 is disconnected from the housing assembly 300.

Optionally, referring to fig. 16, the abutting end 110 is provided with a fan-shaped abutting surface 118, so that the handle 100 is convenient for demolding; when the handle 100 is rotated in the first direction by the second angle, the sector-shaped abutting surface 118 abuts against the jacking portion 326, and the abutting end 110 rotates more smoothly.

On the other hand, the present application also relates to a water purifier, which comprises the purification structure 10 in any one of the above embodiments.

When the purification structure is used, the filter element assembly is detachably arranged in the installation cavity, when the filter element assembly is required to be driven to be separated from the installation cavity so as to take out the filter element assembly, only the handle needs to be driven to rotate by a first angle along a first direction, at the moment, the abutting end is abutted against the pressure bearing part, the handle drives the filter element assembly to move by a first preset distance relative to the installation cavity, when the filter element assembly is firmly arranged in the installation cavity, the filter element assembly is caused to move by the first preset distance and is not enough to be disconnected with the shell assembly, at the moment, the handle is driven to continue to rotate by a second angle along the first direction, at the moment, the abutting end is abutted against the jacking part, as the jacking part is higher than the pressure bearing part, when the jacking part is abutted against the abutting end, the jacking part can jack the handle by a higher distance, so that the handle can drive the filter element assembly to continue to, at this moment, the shell assembly is disconnected with the filter element assembly and can be separated, and the filter element assembly is taken out. Or, when the handle rotates the third angle along first direction, butt end and pressure-bearing portion butt, handle drive filter element group spare relative installation cavity remove the third and predetermine the distance and be enough to make casing subassembly and filter element group spare disconnection and can separate the time, then the rotation mode drive filter element group spare through the handle removes, so can be easier filter element group spare and the casing unit disconnection resistance of overcoming through "lever" principle to can be easier take out filter element group spare.
