Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In one embodiment, as shown in fig. 1 and 2, a water purifier 10 is provided, comprising a filter element assembly 11 and a handle 12, wherein the handle 12 is rotatably connected with the filter element assembly 11. The position of rotating and connecting the handle 12 with the filter element assembly 11 is an adapter point, and the position of rotating and connecting the handle 12 on the filter element assembly 11 is a supporting point.

Further, the water purifier 10 further includes a whole housing assembly 13. The whole machine shell assembly 13 is provided with an installation cavity, and the filter element assembly 11 is detachably installed in the installation cavity. Specifically, as shown in fig. 1 to 6, the filter element assembly 11 can be inserted into the installation cavity, and a force along the axial direction of the installation cavity is provided for the filter element assembly 11 through the handle 12 during the assembling and disassembling process, so that the filter element assembly 11 can be inserted into or pulled out of the installation cavity.

Further, the whole casing assembly 13 is provided with a limiting portion 1321, and the handle 12 is provided with a locking portion 1221 and a detaching portion 1222. As shown in fig. 1 and 3, when the handle 12 rotates forward relative to the filter element assembly 11, the locking portion 1221 abuts against the limiting portion 1321 to press the filter element assembly 11 in the mounting cavity. Specifically, the forward rotation described herein may refer to the counterclockwise rotation of the handle 12 at the angle shown in fig. 1 and 3, where fig. 1 shows a state when the locking portion 1221 is just in contact with the limiting portion 1321, and fig. 3 shows a state when the filter element assembly 11 is fully pressed in the installation cavity, and the locking portion 1221 is fully pressed below the limiting portion 1321.

As shown in fig. 5 and 6, when the handle 12 is inverted relative to the filter element assembly 11, the detaching portion 1222 is pressed against the stopper 1321 to release the filter element assembly 11 from the mounting cavity. Specifically, the handle 12 can be rotated clockwise at an angle shown in fig. 5 and 6, fig. 5 shows a state where the detachable portion 1222 of the handle 12 is initially contacted with the limiting portion 1321 during the reverse rotation, and fig. 6 shows a state where the handle 12 is rotated to a state where the filter element assembly 11 is initially released.

By arranging the locking portion 1221 and the dismounting portion 1222 on the handle 12, the filter element assembly 11 can be locked in the mounting cavity, and meanwhile, the filter element assembly 11 can be loosened from the mounting cavity by utilizing the relative pressing between the dismounting portion 1222 and the limiting portion 1321 in the dismounting process. The operation requirements of the locking process and the disassembling process can be simultaneously realized by means of the single handle 12, the whole structure of the water purifier 10 is simplified, and therefore the manufacturing cost and the failure rate are reduced.

Specifically, in one embodiment, as shown in fig. 1 and fig. 3, during the assembling process, the locking portion 1221 abuts against one side of the limiting portion 1321 close to the bottom wall of the mounting cavity; in the process of detachment, as shown in fig. 5 and fig. 6, the detaching portion 1222 abuts against one side of the limiting portion 1321, which is far away from the bottom wall of the mounting cavity.

In the assembling process, after the filter element assembly 11 is initially placed in the installation cavity, the handle 12 is rotated positively, as shown in fig. 1 and fig. 3, the locking portion 1221 gradually contacts with the limiting portion 1321 and is abutted against each other, at the moment, the limiting portion 1321 applies acting force for locking the filter element assembly 11 in the installation cavity to the handle 12, and finally the filter element assembly 11 is pressed in the installation cavity. During the disassembly process, the handle 12 is turned reversely, as shown in fig. 5 and 6, the disassembly portion 1222 gradually contacts and presses against the limiting portion 1321, the limiting portion 1321 provides a force for the handle 12 to exit the installation cavity, and finally the filter element assembly 11 is released from the installation cavity.

As shown in fig. 8, in one embodiment, the handle 12 is provided with a grip portion 1211, and the grip portion 1211, the transition point and the locking portion 1221 of the handle 12 form a first labor-saving lever. Specifically, the surface of the locking portion 1221 that abuts against the limiting portion 1321 is located on a side of the adapter point away from the holding portion 1211. In the assembling process, as shown in fig. 1 and fig. 3, after a downward acting force is applied to the holding portion 1211, with the help of the first labor-saving lever, the limiting portion 1321 provides support for the locking portion 1221, the handle 12 rotates with a point on the locking portion 1221, which abuts against the limiting portion 1321, as a fulcrum, and the switching point moves in a direction close to the bottom wall of the installation cavity to synchronously drive the filter element assembly 11 connected with the handle 12 to be pressed into the installation cavity.

Alternatively, in an embodiment, a surface of the locking portion 1221, which abuts against the limiting portion 1321, may be located between the holding portion 1211 and the transfer point, as long as the holding portion 1211, the transfer point, and the locking portion 1221 on the handle 12 form a first labor-saving lever. For example, the turning point is located at one end of the handle 12, when the filter element assembly 11 is initially placed in the installation cavity, the handle 12 may be adjusted to a position where the grip portion 1211 is closer to the bottom wall of the installation cavity relative to the turning point, so that the locking portion 1221 is located at one side of the limiting portion 1321 close to the bottom wall of the installation cavity, and then an acting force in a direction away from the bottom wall of the installation cavity is applied to the grip portion 1211, and as the handle 12 rotates, the limiting portion 1321 provides a pressing-down acting force for the locking portion 1221, so that the turning point moves in a direction close to the bottom wall of the installation cavity, and then the filter element assembly 11 is installed and locked in the installation cavity.

Further, as shown in fig. 8, the holding portion 1211, the adapting point and the detaching portion 1222 of the handle 12 form a second labor-saving lever. Specifically, the surface of the detaching portion 1222 abutting against the limiting portion 1321 is located on a side of the adapting point away from the holding portion 1211. As shown in fig. 3, the filter element assembly 11 is mounted and pressed in the mounting cavity, and at this time, the limiting portion 1321 is tightly abutted to the locking portion 1221. When the disassembly is required, as shown in fig. 5 and 6, the upward lifting force is applied to the grip 1211 of the handle 12, and the disassembly portion 1222 is gradually pressed against the limiting portion 1321 by the second labor-saving lever. In the process of reverse rotation of the handle 12, the limiting portion 1321 provides support for the disassembling portion 1222, so that the handle 12 rotates with a point on the disassembling portion 1222, which is abutted against the limiting portion 1321, as a fulcrum, and the transfer point moves in a direction away from the bottom wall of the installation cavity to synchronously drive the filter element assembly 11 to be pulled out of the installation cavity.

Similarly, optionally, a surface of the detaching portion 1222 abutting against the stopper portion 1321 may also be located between the adapting point and the holding portion 1211. Similar to the above-mentioned solution, the surface of the detaching portion 1222 abutting against the limiting portion 1321 may also be located between the holding portion 1211 and the adaptor point. When the filter element assembly 11 is locked in the installation cavity, the disassembling portion 1222 is located at one side of the limiting portion 1321 far away from the bottom wall of the installation cavity, a downward pressure in the direction close to the bottom wall of the installation cavity is provided for the holding portion 1211 at the moment, the disassembling portion 1222 is pressed on the limiting portion 1321 in a propping manner, the switching point moves in the direction far away from the bottom wall of the installation cavity, and then the filter element assembly 11 is pulled out of the installation cavity.

Further, in one embodiment, as shown in fig. 1 and 2, the whole casing assembly 13 includes a support shell 131 and a waterway plate 132 connected to each other, and the mounting cavity is formed in the support shell 131. Specifically, the limiting portion 1321 may be located on the water passage plate 132, or the limiting portion 1321 may be located on the support shell 131.

More specifically, in one embodiment, as shown in fig. 8, the handle 12 includes a middle grip section 121 and connecting sections 122 at both ends of the middle grip section 121. The holding portion 1211 is located on the middle holding section 121, two connecting sections 122 are clamped on two sides of the filter element assembly 11, the two connecting sections 122 are provided with the transition points, and the two connecting sections 122 each include the locking portion 1221 and the detaching portion 1222. In other words, the handle 12 includes two first labor-saving levers and two second labor-saving levers. The holding portion 1211 forms a first labor-saving lever together with the transfer point and the locking portion 1221 on the same connecting section 122, and the holding portion 1211 forms a second labor-saving lever together with the transfer point and the detaching portion 1222 on the same connecting section 122. The whole casing assembly 13 is provided with two limiting portions 1321, the limiting portions 1321 are arranged in one-to-one correspondence with the locking portions 1221, and the limiting portions 1321 are arranged in one-to-one correspondence with the disassembling portions 1222.

The handle 12 is rotatably connected with the supporting point on the filter element assembly 11 through the transfer points on the connecting sections 122 at the two ends, the locking parts 1221 at the two ends of the handle 12 are synchronously contacted with the two limiting parts 1321 in the assembling process, and the disassembling parts 1222 at the two ends of the handle 12 are synchronously contacted with the two limiting parts 1321 in the disassembling process.

Further, in an embodiment, the limiting portion 1321 includes a limiting protrusion, as shown in fig. 8, an abdicating groove 123 is provided between the locking portion 1221 and the detaching portion 1222, as shown in fig. 1 and fig. 3, when the handle 12 rotates forward, the limiting portion 1321 gradually enters the abdicating groove 123 from an opening of the abdicating groove 123 until the locking portion 1221 abuts against a side of the limiting portion 1321 close to the bottom wall of the installation cavity. At this time, the detaching portion 1222 is located on a side of the limiting portion 1321 away from the bottom wall of the mounting cavity. When the handle 12 is turned upside down, as shown in fig. 5 and 6, the detaching portion 1222 gradually presses against the limiting portion 1321 as the limiting portion 1321 exits the receding groove 123.

Specifically, as shown in fig. 8, the openings of the receding groove 123 are located at the end surfaces of the two ends of the handle 12, and the receding groove 123 penetrates through the inner side surface and the outer side surface of the handle 12, so that the locking portion 1221 and the detaching portion 1222 are arranged at an interval. As shown in fig. 3, when the stopper 1321 is located in the receding groove 123, the detaching part 1222 and the locking part 1221 are located at upper and lower sides of the stopper 1321, respectively. Here, the upper side of the limiting portion 1321 refers to a side away from the bottom wall of the mounting cavity, and the lower side refers to a side close to the bottom wall of the mounting cavity.

Further, in one embodiment, as shown in fig. 8, the connecting segment 122 further includes a body portion 1223 connecting the locking portion 1221 and the detaching portion 1222. The main body portion 1223, the locking portion 1221 and the detaching portion 1222 enclose the relief groove 123. The main body portion 1223 is connected to the middle grip segment 121, the position of the main body portion 1223 connected to the middle grip segment 121 is closer to the detachable portion 1222 than the locking portion 1221, and the adaptor point is located on the detachable portion 1222. The middle holding section 121 is an arc-shaped section, the detaching portion 1222 is substantially located on an extension line of two ends of the middle holding section 121, and a cantilever composed of the main body portion 1223 and the locking portion 1221 is suspended outside the middle holding section 121.

As shown in fig. 1 to 6, two connecting sections 122 of a plate-shaped structure are located at two sides of the filter element assembly 11, and are respectively rotatably connected with the filter element assembly 11. The adapter point is located on the detachment portion 1222 based on the location on the body portion 1223 where the intermediate grip segment 121 is connected, relative to the locking portion 1221, closer to the detachment portion 1222. Therefore, as shown in fig. 1 and 3, the latching portion 1221 is disposed offset from the middle grip section 121, and a cantilever formed by connecting the latching portion 1221 and the body portion 1223 is suspended outside the middle grip section 121. In the locking process, when the locking portion 1221 abuts against the limiting portion 1321, the stress at the connection between the locking portion 1221 and the main body portion 1223 is large, and the fracture is likely to occur. Based on this, as shown in fig. 8, a reinforcing rib 125 is provided at a connection portion between the main body portion 1223 and the locking portion 1221, so that the strength of the cantilever is improved.

Further, in an embodiment, as shown in fig. 8, the thickness of the connection portion between the main body portion 1223 and the locking portion 1221 may be set to be greater than the thickness of the other portion on the locking portion 1221, so as to increase the stress capacity at the connection portion between the locking portion 1221 and the main body portion 1223, and improve the strength of the cantilever.

Further, in one embodiment, one of the connecting section 122 and the filter element assembly 11 is provided with a rotating shaft 124, and the other is provided with a slot 111. For example, as shown in fig. 8, the connecting section 122 is provided with a rotating shaft 124, and as shown in fig. 11 and 12, the filter element assembly 11 is provided with a slot 111. The rotating shaft 124 is inserted into the insertion slot 111, a recess 1111 is formed on a side wall of the insertion slot 111, the rotating shaft 124 is provided with a rotation stopping protrusion 1241, and the rotation stopping protrusion 1241 is located in the recess 1111 and used for limiting a rotatable angle of the handle 12 relative to the filter element assembly 11. Specifically, in this embodiment, the switching point is located at the position of the rotating shaft 124, and the supporting point is located at the position of the slot 111.

In the using process, the handle 12 only rotates within a certain allowable range, and the filter element assembly 11 can be assembled and disassembled within the allowable rotating range, so that the convenience of operation is further improved. For example, as shown in fig. 11 and 12, when the handle 12 is turned to the extreme position during the disassembly process, the rotation-stopping protrusion 1241 interferes with the wall surface of the recess 1111 and cannot rotate continuously in the reverse direction, and at this time, the handle 12 is approximately in a state of being distributed along the axial direction of the installation cavity, and the limiting protrusion has exited the receding groove 123, so that the user can conveniently act on the middle holding section 121 to extract the filter element assembly 11.

Further, in one embodiment, as shown in fig. 1-7, the filter cartridge assembly 11 is provided with an outer housing cover 14, the outer housing cover 14 covering the opening of the mounting cavity when the filter cartridge assembly 11 is installed in the mounting cavity.

Further, as shown in fig. 13, the end of the filter element assembly 11 is provided with a snap assembly 15 having elastic restoring capability. As shown in fig. 8, a bayonet 1212 matched with the snap-fastener assembly 15 is provided on the middle holding section 121. As shown in fig. 3, when the locking portion 1221 abuts against the limiting portion 1321 so that the filter element assembly 11 is pressed in the mounting cavity, the elastic buckle assembly 15 can be locked with the bayonet 1212.

The latch assembly 15 with bayonet 1212 cooperates the locking back, handle 12 can not for filter element group spare 11 rotates, thereby locking portion 1221 on the handle 12 all the time with spacing portion 1321 supports tightly, ensures that filter element group spare 11 reliably install in the installation cavity.

Specifically, in one embodiment, as shown in fig. 1 to 7, the handle 12 is disposed at the head end of the filter element assembly 11, the housing cover 14 is disposed at the end face of the head end of the filter element assembly 11, and the housing cover 14 covers the latch assembly 15 on the filter element assembly 11.

In one embodiment, as shown in fig. 13, the central gripping section 121 of the handle 12 is just rotated to a position to fit over the end of the filter cartridge assembly 11 when the filter cartridge assembly 11 is locked in the mounting cavity. The snap-fastener assembly 15 is located on the inner side of the middle holding section 121, and the bayonet 1212 is located on the inner side of the middle holding section 121 facing the snap-fastener assembly 15.

Further, in one embodiment, as shown in fig. 13, the filter element assembly 11 is provided with a button 16, and the button 16 is pressed along the axial direction of the mounting cavity. As shown in fig. 14, the button 16 and the latch assembly 15 are mutually abutted by an inclined surface, so that the pressing motion of the button 16 is converted into the radial movement of the latch assembly 15 along the mounting cavity, so that the latch assembly 15 is withdrawn from the bayonet 1212.

When the filter element assembly 11 needs to be detached, the button 16 is pressed, the snap-fastener assembly 15 moves along the radial direction of the installation cavity to exit the bayonet 1212, then the handle 12 is reversed, and then the filter element assembly 11 is taken out.

Specifically, as shown in fig. 14, the snap-lock assembly 15 is provided with a first inclined surface 1511, the first inclined surface 1511 is disposed obliquely relative to the cross section of the mounting cavity, and a distance between a portion of the first inclined surface 1511 far away from the bottom wall of the mounting cavity and the bayonet 1212 is greater than a distance between a portion of the first inclined surface 1511 near the bottom wall of the mounting cavity and the bayonet 1212. The button 16 is located on a side of the first inclined surface 1511 facing the bayonet 1212. When the button 16 is pressed in a direction approaching the bottom wall of the mounting cavity, the button 16 applies a downward force to the first inclined surface 1511, so that the latch assembly 15 moves in a direction of exiting the bayonet 1212.

The housing cover 14 is provided with a first through hole and a second through hole, when the housing cover 14 covers the filter element assembly 11, the button 16 can be exposed outside the housing cover 14 through the first through hole, so that a user can press the button 16, and the snap assembly 15 can be inserted into the bayonet 1212 through the second through hole.

Further, in one embodiment, as shown in fig. 14, the latch assembly 15 includes a first slider 151 and an elastic restoring member 152. As shown in fig. 13, the first sliding block 151 is slidably disposed with respect to the filter element assembly 11, and the sliding direction is parallel to the cross section of the filter element assembly 11. The elastic restoring member 152 is located between the first sliding block 151 and the filter element assembly 11, and is configured to provide a restoring force for the first sliding block 151 to slide in a direction close to the bayonet 1212. In particular, the elastic return member 152 may be a compression spring, the axis of which is parallel to the cross section of the filter element assembly 11.

Further, in another embodiment, as shown in fig. 15, the end of the filter element assembly 11 is provided with a slide fastener 17, and the middle holding section 121 is provided with a socket matching with the slide fastener 17. When the locking portion 1221 abuts against the limiting portion 1321 so that the filter element assembly 11 is pressed in the mounting cavity, the slide fastener 17 can be slidably inserted into the socket.

When the handle 12 rotates forwards to the filter element assembly 11 and is locked in the installation cavity, the inserting opening is opposite to the sliding buckle 17, the sliding buckle 17 is pushed manually to enable the sliding buckle 17 to be inserted into the inserting opening, so that the handle 12 cannot rotate relative to the filter element assembly 11, and the filter element assembly 11 is reliably in a locking state.

Further, in one embodiment, one of the slide 17 and the intermediate grip segment 121 is provided with a catch 171, and the other is provided with a mating member that mates with the catch 171, and when the slide 17 slides into the receptacle, the catch 171 connects with the mating member catch 171.

Specifically, as shown in fig. 16, the buckle 171 is disposed on the slide buckle 17. The intermediate grip 1211 is provided with a fitting member. When the slider 17 is manually pushed to be inserted into the socket, the catch 171 is engaged with the mating member. Without actively releasing the engagement of the latch 171 with the mating member, the slider 17 cannot exit the socket, and the handle 12 cannot rotate relative to the filter element assembly 11.

Further, in one embodiment, as shown in fig. 1 to 6 and 10, a surface of the limiting portion 1321, which is pressed against the locking portion 1221, is a first mating surface 1322. A plane perpendicular to the axis of the mounting cavity is a reference plane, and the first mating surface 1322 is obliquely arranged relative to the reference plane. When the handle 12 rotates forward, the position of the first engagement surface 1322 that first contacts the locking portion 1221 is the initial locking position, and the position of the first engagement surface 1322 that last contacts the locking portion 1221 is the final locking position. The distance between the stopping locking position and the bottom wall of the installation cavity is larger than the distance between the starting locking position and the bottom wall of the installation cavity.

When the locking part 1221 is pressed against the first mating surface 1322 to lock the filter element assembly 11, as shown in fig. 3, the force provided by the first mating surface 1322 to the locking part 1221 can be decomposed into a first component F1 in the axial direction of the installation cavity and a second component F2 parallel to the reference surface, which effectively prevents the locking part 1221 from being disengaged from the limiting part 1321. Specifically, as shown in fig. 3, the directions of the second component of force F2 are distributed approximately along the opening direction of the receding groove 123, so that the locking portion 1221 can block the limiting portion 1321 from exiting the receding groove 123.

Further, in one embodiment, as shown in fig. 1 to 7 and 9, a surface of the limiting portion 1321, which is pressed against the detaching portion 1222, is a second mating surface 1323. As shown in fig. 3, the removing portion 1222 is spaced from the second mating surface 1323 when the filter element assembly 11 is compressed in the mounting cavity. In other words, the detachment portion 1222 and the second engagement surface 1323 are not in contact at the initial stage of the inversion of the handle 12, and a virtual position exists between the detachment portion 1222 and the second engagement surface 1323, so that the limiting portion 1321 does not obstruct the inversion of the handle 12. After the handle 12 rotates by a predetermined angle, as shown in fig. 4, the detaching portion 1222 contacts the second mating surface 1323, and then the adapting point starts to move in a direction of exiting the mounting cavity, so as to improve the operation feel.

Specifically, in order to further improve the operation feel and avoid the occurrence of a sudden and sudden increase in resistance, as shown in fig. 3 to 6, the surface of the detaching portion 1222 abutting against the second mating surface 1323 is an arc-shaped convex surface. So that the length of the resistance arm of the second labor-saving lever is gradually increased in the process of reversely rotating the handle 12. When the disassembling part 1222 is pressed against the second matching surface 1323, the filter element assembly 11 is just separated from the whole casing assembly 13, the acting force required by the filter element assembly 11 is large, and the ratio of the power arm to the resistance arm is large, so that the labor-saving ratio is large. Along with the handle 12 continues to rotate reversely, the acting force required by disassembling the filter element assembly 11 is reduced, the ratio of the power arm to the resistance arm is smaller, and the labor-saving ratio is reduced. Therefore, the force change required by the user to act on the handle 12 in the whole process is small, and the operation hand feeling is improved.

Further, in one embodiment, as shown in fig. 7, the filter element assembly 11 is provided with a joint 112, the joint 112 is provided with a sealing ring, and the joint 112 is suspended outside the filter element assembly 11. The whole machine shell assembly 13 is provided with an interface 1324 matched with the joint 112, and the opening direction of the interface 1324 is consistent with the direction of the mounting cavity.

Based on the connector 112 is provided with a sealing ring, in the process of disassembling and assembling the filter element assembly 11, the sealing ring can prevent the connector 112 and the interface 1324 from moving relatively. Therefore, the acting force required by disassembly and assembly is large, and the force required to act on the handle 12 is small by means of the first labor-saving lever and the second labor-saving lever, so that the operation convenience is improved.

Specifically, in one embodiment, when the handle 12 is rotated forward, the distance that the transfer point can move in the direction away from the bottom wall of the installation cavity is not less than the distance that the joint 112 is pulled out of the interface 1324; when the handle 12 is turned over, the distance that the transfer point can move in the direction close to the bottom wall of the installation cavity is not less than the distance that the joint 112 is inserted into the interface 1324.

Specifically, in one embodiment, as shown in fig. 9 and 10, the interface 1324 is molded on the water circuit board 132. The force required to insert the adapter 112 into the interface 1324 is relatively large relative to the force required to insert the cartridge assembly 11 into the mounting cavity. Therefore, in order to further improve the labor saving effect, the stopper 1321 is provided on the water passage plate 132. And the length of the middle-size chain can be effectively reduced, and the requirement on manufacturing precision is reduced.

Further, in one embodiment, as shown in fig. 1 to 7, the front surface of the water channel plate 132 faces the outer circumferential surface of the support shell 131, the limiting portion 1321 is disposed on the water channel plate 132, and the limiting portions 1321 are disposed on both left and right sides of the water channel plate 132.

The two locking portions 1221 on the handle 12 correspond to the two limiting portions 1321 one by one, and the two detaching portions 1222 on the handle 12 correspond to the two limiting portions 1321 one by one.

More specifically, as shown in fig. 9 and 10, the interface 1324 is formed on the top surface of the water circuit board 132.

Further, in one embodiment, as shown in fig. 7, the end of the filter element assembly 11 on which the joint 112 is provided is a head end, and the head end is provided with a plurality of joints 112 at intervals side by side. The number of the interfaces 1324 is plural, and the interfaces 1324 are arranged in one-to-one correspondence with the connectors 112. Two supporting points for rotating and connecting with the handle 12 are arranged on the filter element assembly 11, and the supporting points are located at the head end. The two supporting points are respectively positioned at two sides of the joint group. The process filter element group 11 center pin and be on a plurality of the longitudinal section of joint 112 side by side arrangement direction is first reference surface, passes through the strong point and be on a parallel with the longitudinal section of first reference surface is the second reference surface, the joint group with perpendicular distance h1 between the second reference surface is less than the joint group with perpendicular distance h2 between the first reference surface.

In other words, the arrangement of the support points closer to the joint group with respect to the first reference plane further enhances the effect of the forces on the handle 12 on the joint 112. Specifically, when the water passage plate 132 is disposed facing the support housing 131, two support points are located on the filter cartridge assembly 11 near the water passage plate 132.

Further, in one embodiment, as shown in fig. 9 and 10, the water passage plate 132 is provided with two auxiliary plates 1325, and the two auxiliary plates 1325 are located on the left and right sides of the water passage plate 132. The auxiliary plate 1325 overhangs the front surface of the water passage plate 132, and the limiting portion 1321 includes a protrusion located on a side surface of the auxiliary plate 1325 facing away from the support case 131.

When the water passage plate 132 is assembled to the support case 131, two auxiliary plates 1325 are positioned at both sides of the support case 131. The two connecting sections 122 on the handle 12 are respectively located at two sides of the auxiliary plate 1325, the locking portions 1221 included in the connecting sections 122 correspond to the limiting portions 1321 one by one, and similarly, the detaching portions 1222 included in the connecting sections 122 correspond to the limiting portions 1321 one by one.

Further, in one embodiment, as shown in fig. 3, the first engagement surface 1322 of the limiting portion 1321 is disposed obliquely with respect to the water channel plate 132, and a distance between a portion of the first engagement surface 1322 away from the water channel plate 132 and the bottom wall of the mounting cavity is greater than a distance between a portion of the first engagement surface 1322 close to the water channel plate 132 and the bottom wall of the mounting cavity.

Further, the outer peripheral surface of the supporting shell 131 is provided with a limiting rib, and the limiting rib is limited on one side of the auxiliary plate 1325 close to the bottom wall of the mounting cavity. So that when the dismounting portion 1222 is pressed against the limiting portion 1321 on the surface facing away from the bottom wall of the mounting cavity, the limiting portion 1321 and the auxiliary plate 1325 do not move toward the bottom wall of the mounting cavity, thereby providing a reaction force to the dismounting portion 1222 to dismount the filter element assembly 11 from the mounting cavity, and simultaneously releasing the connector 112 from the interface 1324.
