The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

See Figures 1 through 16. The cartridge assembly replacement structure provided in the embodiment of the present application includes: a filter cartridge assembly 200; the filter cartridge assembly 200 is provided with an operation portion capable of being externally biased; and a fixed base 100 for mounting the filter cartridge An assembly 200; a locking mechanism having a locking position for mounting the cartridge assembly 200 on the base 100, and a release position for allowing the cartridge assembly 200 to be disengaged from the base 100; The locking mechanism is actuated to the release position when externally applied.

In the present embodiment, the base 100 is mounted for the filter element assembly 200 and is stationary. During the installation of the filter element, the base 100 can be kept stationary, and the user can complete the removal of the filter element only through the action of the filter element. In an embodiment, the cartridge assembly replacement structure can form a (partial) water purifier housing. Wherein, the base 100 is fixed relative to the water purification housing.

The locking mechanism can be located on the base 100 or on the cartridge assembly 200. In a possible embodiment, the locking mechanism is located on the cartridge assembly 200. The filter element assembly 200 is biased by the operating portion such that the locking mechanism is moved from the locked position to the released position, and the cartridge assembly 200 can be detached from the base 100. In the embodiment shown in FIGS. 1 to 16, the locking mechanism is located on the base 100, and the filter assembly 200 is biased by the operating portion such that the locking mechanism is moved from the locked position to the released position, and the cartridge assembly 200 can be removed from the base. 100 off.

In the present embodiment, the locking mechanism may have a reset element (not shown) that applies a biasing force to the locking mechanism to reset to the locked position. By virtue of the reset element, the locking mechanism can be switched between the locked position and the released position. After the cartridge assembly 200 is disengaged from the base 100, the locking mechanism can be reset to the locked position by the reset element. In particular, the reset element may comprise a resilient element such as a spring.

In order to facilitate the user to install the filter element assembly 200, in a preferred embodiment, the filter element assembly replacement structure may further include an unlocking mechanism. The unlocking mechanism can open the locking mechanism when the cartridge assembly 200 is inserted into the base 100.

The process of opening the locking mechanism by the unlocking mechanism may refer to the process of moving the locking mechanism from the locking position to the releasing position, and the opened maximum position (also referred to as the second releasing position) may be the same as or different from the releasing position ( For example, if the opening diameter is larger or smaller than the release position, it is only necessary to enable the filter element assembly 200 to complete the insertion locking.

Of course, the opening process of the locking mechanism can also be different from the moving process of the locking mechanism from the locking position to the releasing position. For example, the opening process of the locking mechanism by the unlocking mechanism can be a push-to-open process in the insertion direction (similar to a hinge swing). The movement of the locked position to the release position may be a radial translational movement.

The unlocking mechanism may be disposed on the filter mechanism or on the base 100. By providing the unlocking structure, the locking mechanism can be actuated to open when the cartridge assembly 200 is inserted into the base 100. The filter element assembly 200 can be mounted on the base 100 by operating the filter element assembly 200 by using an unlocking mechanism, and the installation of the filter element assembly 200 is very convenient.

The filter element assembly 200 of the present embodiment has an operation portion for the user to apply force. The user can unlock the release mechanism of the operation unit of the filter element assembly 200, so that the filter element assembly 200 can be detached from the base 100. The filter element assembly 200 can be pulled out of the base 100. The operation portion may be a part of the filter element assembly 200 that is biased by the user, or may be disposed on the force-receiving member of the filter element assembly 200 for the user to apply force. The operating portion moves with the cartridge assembly 200 during the process of replacing the cartridge assembly 200.

In the embodiment, the filter element assembly replacement structure allows the user to operate only the filter element assembly 200, and the base unit 100 remains fixed without the need to operate the base 100, thereby facilitating the user's one-hand operation on the filter element assembly 200, which is very convenient. Meanwhile, when the filter unit 200 is detached from the susceptor 100 by the operation portion of the filter element assembly 200, the space required for moving the susceptor 100 by the detachment of the filter element assembly 200 can be reduced, and the space required for the detachment of the filter element assembly 200 can be reduced. Good installation flexibility.

In addition, in the embodiment, the base 100 of the filter element replacement structure is fixed, and only the filter element assembly 200 needs to be operated, so that the water purifier can be placed laterally, that is, the length direction of the filter element assembly 200 is parallel to the horizontal direction, not only It has higher installation flexibility and is more convenient for users to operate.

The filter element assembly 200 has an insertion end 1 for insertion into the base 100 and an operating end 2 facing away from the insertion end 1. The operating portion is located on the operating end 2 for user operation. The operation portion may be provided with a structure that is easy for the user to apply force.

In an embodiment, the cartridge assembly 200 is generally cylindrical in configuration. The insertion end 1 of the cartridge assembly 200 can be inserted into the base 100. Correspondingly, the base 100 may be provided with an insertion hole 15 into which the insertion end 1 is inserted. At the same time, sealing measures can be provided in the insertion end 1 and the insertion hole 15 to prevent fluid leakage and to avoid poor water production. The insertion end 1 has a flow path that opens into the interior of the filter element assembly 200 and cooperates with the flow path 7 in the base 100 to perform filtration of the incoming water.

In one embodiment, the locking mechanism includes a snap-fit assembly 6 disposed on the base 100 to clamp the insertion end 1. The snap assembly 6 includes at least one clamping member distributed in a circumferential direction. Wherein the at least one of the clamping members moves radially outward from the locking position to the release position. At least one of the clamping members moves radially inwardly from the release position to the locked position.

The locking mechanism is mounted inside the base 100, and the clamping member includes a clamping plate disposed in the base 100. The plurality of clamping plates are configured to form an engaging opening and constitute a partial insertion hole 15. Wherein, the plurality of clamping plates are movable in the radial direction. A spring is provided in the base 100 to apply a biasing force to the plurality of clamping plates to move to the locking position, so that the clamping plate is held in the locked position when there is no external force.

Of course, the locking mechanism can also be other mechanisms, such as an insertion structure, a flip structure, and the like. Only the locking mechanism can realize the locking position and the release position switching by the action, and the action of the locking mechanism is not limited to the radial movement, and may also be a rotation, an insertion, a deformation or the like.

In the present embodiment, the insertion end 1 is provided with a blocking portion 12 that cooperates with the engaging assembly 6. The blocking portion 12 is blocked by the snap-fit assembly 6 when the snap-fit assembly 6 is in the locked position such that the filter cartridge assembly 200 cannot be disengaged from the base 100. As shown in FIG. 15 and FIG. 16 , the side wall of the insertion end 1 is provided with a convex ring structure 14 , and the blocking portion 12 may be an end surface of the convex ring structure 14 near the operation end 2 .

Specifically, the engaging component 6 is formed with an engaging opening through which the insertion end 1 passes. When the engaging component 6 is in the locking position, the blocking portion 12 is located on a side of the engaging opening away from the operating end 2 and cannot pass through the engaging opening. When the engaging component 6 is in the release position, the blocking portion 12 can pass through the engaging opening.

As shown in FIG. 9 , when the filter element assembly 200 is mounted on the base 100 , the side of the engaging component 6 away from the operating end 2 has a fitting surface (not labeled) that can be attached to the blocking portion 12 . By engaging the sealing surface with the blocking portion 12, the insertion end 1 of the filter element assembly 200 is restricted from being unplugged from the insertion hole 15 of the base 100, and the locking of the filter element assembly 200 is achieved.

In order to facilitate the user to install the filter element assembly 200 on the base 100, the filter element assembly replacement structure may also be provided with an unlocking mechanism. The unlocking mechanism can move the at least one clamping member radially outward when the filter cartridge assembly 200 is inserted into the base 100, so that the blocking portion 12 of the filter cartridge assembly 200 passes through the engaging opening. . After the blocking portion 12 passes the engaging opening, the snap-fit assembly 6 is reset to the locked position to lock the cartridge assembly 200.

The unlocking mechanism includes a first end of the insertion end 1 on a side of the blocking portion 12 away from the operating end 2 and/or a side of the engaging component 6 adjacent to the operating end 2 Bevel 31. When the filter element assembly 200 is inserted into the base 100, the blocking portion 12 of the filter element assembly 200 relies on the first inclined surface 31 to open the engaging assembly 6 to pass through the engaging opening.

In this embodiment, the size of the engaging opening to be unlocked by the unlocking structure may be the same as or different from the size of the engaging opening when the position is released. The first inclined surface 31 is disposed on the engaging component 6; the first inclined surface 31 causes the cross-sectional area of the engaging opening to gradually decrease along the direction in which the filter element assembly 200 is inserted into the base 100.

In the embodiment shown in FIG. 9, the insertion end 1 and the engaging assembly 6 are each provided with a first inclined surface 31. The first inclined surface 31 of the insertion end 1 is disposed on the convex ring structure 14 and is located on a side of the blocking portion 12 away from the operation end 2.

In an embodiment, the filter element replacement structure may further be provided with an opening mechanism that cooperates with the operating portion. The operation portion is actuated by driving the opening mechanism when externally biased to move the locking mechanism from the locked position to the release position. Among them, the opening mechanism transmits the force received by the operating portion, thereby opening the locking mechanism. The opening mechanism can be part of the cartridge assembly 200, such as the embodiment illustrated in Figures 8-16; the opening mechanism can also be a component disposed outside of the cartridge assembly 200, such as the embodiment illustrated in Figures 1-7.

In the present embodiment, the opening mechanism operates by the operation of the locking mechanism, and the base 100 is fixed during the driving process. With the opening mechanism, the locking mechanism is driven to the release position by applying force to the operating portion of the cartridge assembly 200 without actuating the base 100. In this embodiment, the opening mechanism can transmit the force received by the operating portion, and the position of the locking mechanism can be switched to the release position.

Wherein, the opening mechanism drives the locking mechanism by itself, wherein the opening mechanism operates in a plurality of ways. For example, the opening mechanism can drive the locking mechanism by moving along the length direction of the cartridge assembly 200, or can drive the locking mechanism by rotation. Of course, in a possible embodiment, the opening mechanism can also achieve a drive locking mechanism by other movements, such as: the opening mechanism has two mating elements, the positional switching of the locking mechanism is achieved by the separation or engagement of the two elements, and the like.

In the specific embodiment shown in Figures 8-16. The opening portion rotates when the operating portion is externally biased, and the opening mechanism moves from the locking position to the releasing position by rotationally driving the locking mechanism. In this embodiment, the opening mechanism can be disposed on the cartridge assembly 200 to follow the filter cartridge assembly 200 for movement. In such a configuration, the user only needs to apply force to the operating portion to rotate the filter element assembly 200, thereby opening the locking mechanism to the release position, completing the removal of the filter element assembly 200, and the operation is simple.

In this embodiment, the opening mechanism can rotate with the filter cartridge assembly 200. Specifically, the opening mechanism includes a support portion 30 that protrudes in the radial direction on the filter element assembly 200. The operating portion enables the filter cartridge assembly 200 to rotate the support portion 30 about an axis parallel to the longitudinal direction of the cartridge assembly 200; the support portion 30 rotates the snap assembly 6 from the locked position Prolonged in the radial direction to the release position.

The insertion end 1 is evenly distributed with two or more of the support portions 30 in the circumferential direction. In order to facilitate the support portion 30 to radially support the snap assembly 6 to the release position when the rotation of the filter assembly 200 is locked by the locking mechanism, the support portion 30 and the engagement assembly 6 are in the same axial position. on.

The outer diameter of the support portion 30 may be larger than the outer diameter of the blocking portion 12 or smaller than the outer diameter of the blocking portion 12 . Of course, in the embodiment shown in FIG. 16, the side of the blocking portion 12 near the operating end 2 is provided with an annular groove structure 28, and the supporting portion 30 is disposed in the annular groove structure 28, and the supporting portion 30 a support protrusion that protrudes radially outward, the two support protrusions are evenly arranged in the circumferential direction, and an outer diameter of the support portion 30 (support protrusion) is equal to an outer diameter of the blocking portion 12 (of course In some embodiments, the outer diameter of the support portion 30 (support protrusion) and the outer diameter of the blocking portion 12 may also be unequal.

Further, the engaging assembly 6 is formed with an engaging opening (not labeled). The edge of the engaging opening has a first portion and a second portion that are different in distance from the axis. The distance of the first portion from the axis is greater than the distance of the second portion from the axis. When the support portion 30 is aligned with the first portion in the radial direction, the engaging assembly 6 is not extended to the release position; when the support portion 30 is rotated to be aligned with the second portion in the radial direction, The snap assembly 6 is extended to the release position. The engaging portion is in contact with the first portion and the second portion having different distances from the axis at the supporting portion 30, so that the supporting portion 30 is radially expanded at the second portion.

The distance from the first portion to the axis is L1, the distance from the second portion to the axis is L2, and the distance from the outer edge of the support portion 30 to the axis is L3; wherein, L1≥L3 >L2. Further, a distance between the first portion and the axis is a maximum distance between an edge of the engaging opening and the axis; a distance of the second portion at the axis is an edge of the engaging opening and the a minimum distance of the axis, a distance of the engaging opening from the first portion to the second portion to the axis, and a distance from the second portion to the first portion and the axis The distance gradually increases.

In a specific embodiment, the abutting position of two adjacent clamping members forms the first portion; the intermediate position of the clamping member forms the second portion. In a specific embodiment, when the two engaging members are oppositely located in the locking position, the engaging openings formed by the two engaging members have an elliptical shape.

In order to facilitate the user to pull the filter element assembly 200 out of the base 100, the influence of the resistance caused by the sealing fit between the insertion end 1 and the base 100 is reduced. In a preferred embodiment, the base 100 is further provided with a push-out structure. When the filter element assembly 200 drives the support portion 30 to rotate from the first portion to the second portion, the push-out structure pushes the filter element assembly 200 away from the filter element assembly 200 in the direction of the base 100.

Specifically, the base 100 has an insertion opening for inserting the filter element assembly 200; the push-out structure includes an arcuate protrusion 19 disposed on a side of the base 100 having an insertion opening. Specifically, the curved protrusion 19 is located on a surface of the base 100 provided with an insertion opening. The height of the curved protrusion 19 protruding from the surface of the base 100 gradually increases in a direction in which the support portion 30 rotates from the first portion to the second portion. Specifically, the position of the curved protrusion 19 may be smaller than the outer diameter of the filter element assembly 200. The annular surface of the filter element assembly 200 facing away from the operating end may be provided with a raised portion 29 (a ribbed structure in Fig. 16) that cooperates with the curved projection 19. The filter element assembly 200 is formed with an annular surface around the insertion end 1.

When the cartridge assembly 200 is mounted on the base 100, the annular surface of the cartridge assembly 200 conforms to the surface of the base 100. At this time, the convex portion 29 of the filter element assembly 200 is located at the lowest point of the curved protrusion 19 (the position where the surface of the base 100 is not protruded), and the rotating filter element assembly 200 drives the convex portion 29 to rotate about the axis. The raised portion 29 is in contact with the curved projection 19 facing away from the elongated upper end surface of the base 100 and supported by the curved projection 19. As the cartridge assembly 200 continues to rotate along the axis, the arcuate projections 19 progressively urge the projections 29 away from the cartridge assembly 200 in the direction of the base 100, causing the cartridge assembly 200 to progressively engage the base. The seat 100 is detached.

Of course, the push-out structure is not limited to the above-mentioned arc-shaped protrusion 19, and may be a guide rail that gradually moves away from the base 100 along the rotation direction of the first portion to the second portion, and the push-out structure may also be disposed on the filter element assembly 200. The push-out structure converts the rotation of the cartridge assembly 200 into a force that moves the cartridge assembly 200 away from the base 100 in an axial direction, pushing the cartridge assembly 200 out of the base 100.

In the present embodiment, the operating portion includes a knob 20 that is fixed to the operating end 2. The filter cartridge assembly 200 is rotated by the knob 20. The knob 20 has a flat structure and is perpendicular to the end surface of the operating end 2. In other embodiments, the operation portion may be in the form of a handle or the like. Considering that the operation portion has a plurality of implementation manners, it is only required to be able to drive the filter element assembly 200 to rotate, and the present application is not limited thereto.

In the above embodiment, the support portion 30 and the mating engagement assembly 6 are provided. When the cartridge assembly 200 is inserted into the base 100, the cartridge assembly 200 can be inserted into the base 100 along the direction in which the support portion 30 is aligned with the first portion of the engagement opening. The filter cartridge assembly 200 radially expands the snap-fit assembly 6 under the action of the first ramp 31 (unlocking mechanism) such that the blocking portion 12 passes through the snap-in opening, and then the snap-fit assembly 6 is reset to the locked position to lock the cartridge assembly 200. At this time, the support portion 30 does not affect the blocking portion 12 through the engaging assembly 6, nor does it disengage the engaging assembly 6, and the engaging assembly 6 and the supporting portion 30 are located at the same axial position. The outer edge of the support portion 30 may meet the edge of the engagement opening (which may also be referred to as an inner surface, an inner edge).

When the insertion end 1 is in contact with the engaging assembly 6, due to the presence of the resetting element, the user can apply the force of pushing the filter element assembly 200 along the length of the filter element assembly 200 to the filter element assembly 200 through the operating portion, by virtue of the action of the first inclined surface 31. The snap-fit assembly 6 is urged in the radial direction to radially expand the snap-in opening such that the blocking portion 12 passes through the snap-fit assembly 6.

In order to facilitate the user to install the filter element assembly 200, the locking mechanism locks the filter element assembly 200, so the support portion 30 needs to be positioned at the first portion of the snap-fit assembly 6. Based on this consideration, the base 100 may also be provided with a guiding structure. The guiding structure can guide the support portion 30 to the first portion when the filter element assembly 200 is inserted into the base 100.

Through the guiding structure, the supporting portion 30 can be guided to the supporting portion 30 along the longitudinal direction of the cartridge assembly 200 (which can also be regarded as the axial direction), and the first portion can be aligned, and the blocking portion 12 can be passed through the card by applying a force to the operating portion. In conjunction with the cartridge assembly 200 being locked by the snap-fit assembly 6 (ie, the cartridge assembly 200 is in a state of being mounted to the base 100), the support portion 30 is radially aligned with the first portion. In this way, the filter element assembly 200 can be located at a predetermined position during installation, and the locking assembly 6 can be unlocked to the release position by rotating the filter element assembly 200 through the operating portion. The operation is very convenient, and the user does not need to manually position the filter element assembly 200. Fast.

Specifically, the guiding structure includes a first guide rail 21. The filter element assembly 200 is provided with a guide protrusion 26 that moves along the first guide rail 21. When the cartridge assembly 200 is inserted into the base 100, the guide projection 26 moves along the first rail 21 and the support portion 30 is guided to the first portion.

In addition, in order to facilitate the user to disassemble the filter element assembly 200, it is known that the support portion 30 has been aligned with the second portion, and the engaging assembly 6 is extended to the release position to prevent the user from pulling out the filter element assembly 200 due to insufficient rotation or excessive rotation. The guide structure further includes a second guide rail 22 for moving the guide projection 26, and a communication rail 23.

The communication rail 23 communicates the first rail 21 with the second rail 22 . When the guide protrusion 26 moves along the communication rail 23, the support portion 30 expands the engaging assembly 6 from the locked position to the release position. The guide protrusion 26 moves along the communication rail 23 when the filter element assembly 200 moves out of the base 100. Further, the second rail 22 extends linearly along the length direction of the cartridge assembly 200; the first rail 21 extends in a curved direction along the longitudinal direction of the cartridge assembly 200; and the communication rail 23 extends in the circumferential direction.

As shown in FIGS. 13 and 14, one of the first rails 21, one of the second rails 22, and one of the first rails 21 and the second rails 22 communicate with each other to form a rail group. The guiding structure comprises two sets of guide rails, and a first inlet and outlet 24 and a second inlet and outlet. The first inlet and outlet port 24 and the second inlet and outlet are used for the guide protrusions 26 to enter and exit the guide rail group. Through the first inlet and outlet 24, the second inlet and outlet, the guide projections 26 can be removed from the guiding structure, so that the filter element assembly 200 is completely removed for easy replacement.

The first rail 21 in one rail group and the second rail 22 in the other rail group are in communication with the first inlet and outlet 24. The second rail 22 in the set of rails and the first rail 21 in the other set of rails are in communication with the second inlet and outlet. The two sets of guide rails can be symmetrically distributed, and two guide protrusions 26 can be correspondingly arranged in the circumferential direction of the filter element assembly 200, respectively corresponding to the first inlet and outlet 24 and the second inlet and outlet. In other embodiments, the first rail 21 and the second rail 22 may not share the same inlet and outlet.

The first rail 21, the second rail 22, and the communication rail 23 may be an elongated through hole structure or a groove structure 28 that provides a moving track. In the embodiment shown in FIG. 13 to FIG. 14 , the base 100 is further provided with a support cylinder 300. The support cylinder 300 is sleeved on the filter assembly 200 when the filter assembly 200 is mounted on the base 100. The filter element assembly 200 is external. The guiding structure is disposed on the support cylinder 300. The first rail 21, the second rail 22, and the communication rail 23 each penetrate the support cylinder 300 in the radial direction. Of course, the first rail 21, the second rail 22, and the communication rail 23 may also be in the form of grooves.

The embodiments shown in Figures 8 through 16 of the present application are described in detail below for a better understanding of the present application.

As shown in Figure 15. The cartridge assembly 200 has a cylindrical body 27 and an insertion end 1. A knob 20 of a flat structure forming an operation portion is provided on an end surface of the filter element assembly 200 facing away from one end of the insertion end 1. The cartridge assembly 200 can be rotated about the axis parallel to the longitudinal direction of the cartridge assembly 200 by the knob 20.

The base 100 is provided with an insertion hole 15 through which the insertion end 1 enters, and an insertion opening is formed on the outer surface of the base 100. A support cylinder 300 is also fixedly coupled to the base 100. When the filter cartridge assembly 200 is mounted on the base 100, the support cylinder 300 encloses the cartridge assembly 200. The support cylinder 300 can support the filter element assembly 200 to prevent all the weight of the filter element assembly 200 from being taken up by the insertion end 1 and the insertion hole 15 at the same time, while avoiding long-term exposure of the filter element assembly 200 to be dusty.

A guiding structure for inserting or withdrawing the filter element assembly 200 is also provided on the support cylinder 300. Wherein, the guiding structure comprises two rail sets and a first inlet and outlet 24 and a second inlet and outlet. Each of the rail sets includes a first rail 21, a second rail 22, and a guide rail 23 that connects the first rail 21 and the second rail 22. The first guide rail 21 extends circumferentially along the longitudinal direction of the support cylinder 300, and the second guide rail 22 extends linearly along the longitudinal direction of the support cylinder 300.

As shown in FIG. 13 and FIG. 14, the first rail 21 in one rail group and the second rail 22 in the other rail group communicate with the first inlet and outlet 24; the second rail 22 in the rail group is The first rails 21 of the other rail group are all in communication with the second inlet and outlet. A communication section 25 is further disposed between the first rail 21 and the second rail 22 and the first inlet and outlet 24, and the communication section 25 also extends in a straight line, and is away from the first inlet and outlet 24 along the connecting section 25 at the filter element assembly 200. The connecting section 25 is arranged to guide the filter element assembly 200 into the first guide rail 21 during movement. The base 100 and the support cylinder 300 may be connected to each other or indirectly, and the present application is not limited thereto. The base 100 and the support cylinder 300 can participate in forming an outer casing of the water purifier.

The outer diameter of the insertion end 1 is smaller than the outer diameter of the cylindrical body 27 of the filter cartridge assembly 200. The insertion end 1 is provided with a convex ring structure 14, and a side of the convex ring structure 14 adjacent to the operation end 2 is provided with a blocking surface (blocking portion 12), and a supporting protrusion (support portion 30) is provided. The outer diameter of the support protrusion is equal to the outer diameter of the collar structure 14. The support projections are evenly distributed in the circumferential direction by two, so that the snap-fit assembly 6 can be opened to the release position by rotating 90 degrees. A side of the collar structure 14 facing away from the operating end 2 is provided with a first bevel 31.

The base 100 has a base housing, and the engaging opening is disposed on the base housing. The engaging assembly 6 is mounted inside the base housing and forms an engaging opening on the inner side of the insertion opening (the insertion opening and the engaging opening are both Insert a part of the hole 15). The snap-fit assembly 6 has two opposite clamping plates, each of which is provided with a curved edge forming an edge of the engaging opening. The abutting portions of the two clamping plates form two first portions and are in one-to-one correspondence with the two supporting protrusions. After the support protrusion is rotated by 90 degrees, the two support protrusions are respectively aligned with the intermediate positions of the two clamping plates, and the two clamping plates are pushed radially outward to the release position. The base 100 is internally provided with an elastic member that applies a movement toward the locking position of the two clamping plates. The edge of the engaging opening is also the first inclined surface 31 so as to cooperate with the first inclined surface 31 of the convex ring structure 14 so as to be pushed away and passed by the convex ring structure 14.

When the user needs to remove the filter element assembly 200 from the base 100 (or the water purifier housing), the filter element assembly 200 is first rotated by the knob 20, and the guide protrusion 26 on the filter element assembly 200 is rotated 90 degrees around the communication rail 23 to the first One end of the two guide rails 22, the wall connecting the ends of the guide rails 23, can prevent the guide projections 26 from continuing to move in the circumferential direction, reminding the user that the filter cartridge assembly 200 can be pulled out at this time. During rotation of the cartridge assembly 200, the support projection is rotated from the first portion to the second portion to disengage the snap assembly 6 from the locked position to the released position. At the same time, under the action of the curved protrusions 19, the filter element assembly 200 is automatically moved outward (extracting direction) by a certain distance with the rotation, thereby reducing the user's force. The user pulls the filter element assembly 200 outward, and the two guide projections 26 move along the second guide rail 22 until they are removed from the first inlet and outlet 24 and the second inlet and outlet.

When the user needs to mount the (new) filter element assembly 200 to the base 100 (or the water purifier housing), the two guiding protrusions 26 are introduced into the guiding structure from the first inlet and outlet 24 and the second inlet and outlet, and continue. The filter element assembly 200 is pushed and guided by the communication section 25 into the first rail 21 until the two support projections are axially aligned with the two first portions. The filter cartridge assembly 200 is then pushed toward the base 100 by the knob 20, and the insertion end 1 of the cartridge assembly 200 is opened and passed by the first ramp 31, and is reset to the lock after the blocking portion 12 passes the rear latching assembly 6. The position locks the insertion end 1 and the two support portions 30 are radially aligned with the two first portions to complete the installation of the filter element assembly 200.

Refer to the embodiment shown in Figures 1-7. The opening portion moves the opening mechanism along the longitudinal direction of the cartridge assembly 200 when externally applied by the operating portion. The opening mechanism moves the locking mechanism from the locked position to the release position by moving along the length of the cartridge assembly 200.

In this embodiment, the opening mechanism can be movably mounted to the base 100 or can be detachably mounted with the filter cartridge assembly 200. Of course, the opening mechanism can also include a plurality of detachable components, a portion of which is mounted to the base 100 and another portion of which is mounted to the filter assembly 200.

Specifically, the operating portion is provided with a rotatably-forced member 3. The opening mechanism includes a distracting member 4 that cooperates with the force receiving member 3. The expansion member 4 is movable in the direction in which the filter element assembly 200 is inserted into the base 100 when the force receiving member 3 is biased, and the snap assembly 6 is extended from the locked position to the release position. .

In order to reduce the influence of the resistance formed by the sealing means between the filter element assembly 200 and the base 100, the force receiving member 3 can also move the filter element assembly 200 away from the base 100 when the force receiving member 3 is rotated. Specifically, after the expansion member 4 moves along the length direction of the filter element assembly 200 to open the engagement assembly 6 to the release position, the expansion member 4 can be restrained by the base 100 and cannot continue to move toward the base 100 in the direction of the filter element assembly 200. At this time, the force receiving member 3 can continue to rotate, and the expansion member 4 applies an opposite force to the force receiving member 3 or the filter element assembly 200 to move against the filter element assembly 200 in a direction away from the base 100.

The extending member 4 is provided with a distracting portion near one end of the base 100; the engaging assembly 6 is provided with an acting portion that can cooperate with the distracting portion. The expansion portion and/or the action portion are provided with a second slope 13 . The second bevel 13 causes the distraction member 4 to radially expand the snap-fit assembly 6 from the locked position to the release position as the filter cartridge assembly 200 is inserted into the base 100.

The force receiving member 3 is rotated about a rotation axis perpendicular to the longitudinal direction of the filter element assembly 200. The force receiving member 3 has a first rotational position and a second rotational position along its rotational direction. When the force receiving member 3 is rotated from the first rotational position to the second rotational position, the expansion member 4 is pushed to move in the direction in which the filter cartridge assembly 200 is inserted into the base 100.

Wherein, the force receiving member 3 includes a handle. To facilitate the user's gripping operation, the handle is gradually erected at an end of the filter element assembly 200 away from the insertion end 1 when the handle is rotated from the first rotational position to the second rotational position. In the embodiment shown in FIGS. 2 to 4, the force receiving member 3 has a semicircular shape, and both ends are rotatably coupled to the operating end 2. It should be noted that the force receiving member 3 of the present application is not limited thereto, and the force receiving member 3 may have other shapes, such as a straight rod shape, a polygonal line shape, a partial curved shape, and the like.

In order to move the expansion member 4 in the direction of the base 100 by the force receiving member 3, in the embodiment shown in Fig. 2, the force receiving member 3 has a pushing surface 8 which rotates together about the rotation axis. When the force receiving member 3 is rotated from the first rotational position to the second rotational position, the distance between the contact portion of the pushing surface 8 and the distracting member 4 and the rotational axis gradually increases.

Referring to FIG. 2, the pushing surface 8 is located at both ends of the force receiving member 3, and the pushing surface 8 may be a curved surface structure. The force receiving member 3 in this embodiment has a simple structure, and is rotated by the pivoting shaft 9 (the pivot axis 9 is perpendicular to the longitudinal direction of the cartridge assembly 200, that is, the axis perpendicular to the axis, the pivot axis 9 provides the rotation axis). The pushing surface 8 can push the expansion member 4 to move along the length of the filter element assembly 200.

In another embodiment, as shown in FIGS. 3 and 4, the opening mechanism further includes a pushing member 10 disposed at the operating end 2. When the force receiving member 3 is rotated from the first rotational position to the second rotational position, the pusher 10 is moved radially outward. When the pusher 10 is moved radially outward, the spreader 4 is moved in the direction in which the cartridge assembly 200 is inserted into the base 100. In order to prevent the pushing member 10 from being exposed, a shielding cover 18 may be provided on the operating end 2 to block the pushing member 10.

Wherein, the force receiving member 3 is further provided with a pushing rod 16 connecting the two ends thereof. The operating end 2 is provided with two pushing members 10, and when the force receiving member 3 is rotated from the first rotating position to the second rotating position, the pushing rod 16 directly pushes a pushing member 10 radially outward, and correspondingly, the pushing At the same time, the piece 10 pushes the other pushing member 10 to push in the opposite direction (schematically, for example, the two pushing members 10 simultaneously mesh with a fixed gear, by which the two pushing members 10 move in opposite directions in the radial direction. ). Specifically, the pushing member 10 is provided with a third inclined surface 11 at a radially outer end. When the pusher 10 moves radially outward, the extension member 4 is pushed by the third inclined surface 11 to move in the direction in which the filter cartridge assembly 200 is inserted into the base 100.

The distracting member 4 includes a cylindrical structure that is mounted on the base 100 and can be sleeved outside the filter element assembly 200. The expansion portion is disposed at an end of the cylindrical structure near the base 100. The barrel structure is movable relative to the base 100 along the length of the cartridge assembly 200. That is, the expansion member 4 is movably supported (indirectly or directly) on the base 100. Two ends of the cylindrical structure adjacent to the base 100 are circumferentially provided with two or more insertion projections 5, and the second inclined surface 13 is provided on the insertion projection 5.

In this embodiment, as shown in FIG. 7, the base housing is provided with a plurality of rectangular openings 17, the action portion of the clamping plate (also a convex structure, and the convex structure at the position indicated by reference numeral 6 in FIG. The raised structure is part of the clamping plate) located in the rectangular opening 17 and is likewise provided with a second bevel 13. When the upper end of the tubular structure of the distracting member 4 is pushed by the force receiving member 3, the distracting member 4 drives the insertion protrusion 5 to move toward the base 100, and the distracting portion cooperates with the acting portion to axially extend the distracting member 4 The motion changes into a radial movement of the clamping plate causing the snap-fit assembly 6 to move to the release position.

In this embodiment, the base 100 is further provided with a support cylinder 300. The support cylinder 300 is sleeved outside the filter element assembly 200 when the filter element assembly 200 is mounted on the base 100. The cylinder structure is sleeved between the support cylinder 300 and the filter element assembly 200. The expansion member 4 is movably mounted on the support cylinder 300.

The embodiments shown in Figures 1 through 7 of the present application are described in detail below for a better understanding of the present application.

The cartridge assembly 200 has a cylindrical body 27 and an insertion end 1. The end face of the filter element assembly 200 facing away from the operating end 2 of the insertion end 1 is provided with a rotatable semi-circular handle. The pilling cylinder (the struts 4) can be pushed along the length of the cartridge assembly 200 by erecting the handle on the end face of the operating end 2.

The expansion cylinder is movably supported in the support cylinder 300, and the base 100 is provided with an insertion hole 15 for the insertion end 1 to enter, and an insertion opening is formed on the outer surface of the base 100. A support cylinder 300 is also fixedly coupled to the base 100. When the filter cartridge assembly 200 is mounted on the base 100, the support cylinder 300 encloses the cartridge assembly 200. The support cylinder 300 can support the filter element assembly 200 to prevent all the weight of the filter element assembly 200 from being taken up by the insertion end 1 and the insertion hole 15 at the same time, while avoiding long-term exposure of the filter element assembly 200 to be dusty. Both the support cylinder 300 and the expansion cylinder can guide the insertion or removal of the filter element assembly 200, so that the insertion end 1 is aligned with the insertion opening of the base 100 during installation.

The outer diameter of the insertion end 1 of the cartridge assembly 200 is smaller than the outer diameter of the cylindrical body 27 of the cartridge assembly 200. The insertion end 1 is provided with a convex ring structure 14, and a side of the convex ring structure 14 adjacent to the operation end 2 is provided with a blocking surface (blocking portion 12). A side of the collar structure 14 facing away from the operating end 2 is provided with a first bevel 31.

The base 100 has a base housing, and the engaging opening is disposed on the base housing. The engaging assembly 6 is mounted inside the base housing and forms an engaging opening on the inner side of the insertion opening (the insertion opening and the engaging opening are both Insert a part of the hole 15). The snap-fit assembly 6 has two opposing clamping plates (one of the clamping members), each of which is provided with a curved edge forming an edge of the engaging opening. The abutting portions of the two clamping plates form two first portions and are in one-to-one correspondence with the two supporting protrusions.

An elastic member that applies a movement toward the locking position to the two clamping plates is provided inside the base 100. The edge of the engaging opening is also the first inclined surface 31 so as to cooperate with the first inclined surface 31 of the convex ring structure 14 so as to be pushed away and passed by the convex ring structure 14. The base housing is provided with a rectangular opening 17 into which the active portion of the clamping plate projects and cooperates with the insertion projection 5 of the end of the expansion cylinder. Due to the presence of the elastic member, when the filter element assembly 200 has been mounted on the base 100 or is not mounted in the state of the base 100 (ie, the snap-fit assembly 6 is in the locked position), the clamping plate will be moved away from the base by the first inclined surface 31. The direction of the seat 100 pushes the distraction member 4 so that the distraction member 4 is reset.

When the user needs to detach the cartridge assembly 200 from the base 100 (or the water purifier housing), the handle is first erected at the operating end 2 by a rotary handle. As the handle is erected, the push surface 8 of the handle pushes the expansion cylinder toward the base 100. The expansion cylinder moves the clamping plate in the radial direction by the second inclined surface 13 to open the engagement opening to the release position. The handle continues to be erected, and the end of the insertion protrusion 5 is pushed against the limit (such as the clamping plate or the limit portion on the base 100) and cannot continue to move toward the base 100. Under the reaction force, the filter element assembly 200 is automatically moved outward (extracting direction) by a certain distance as the handle rotates to reduce the user's force. Finally, the user can pull out the filter element assembly 200 outwardly, and the filter element assembly 200 does not need to be rotated during the pulling out process.

When the user needs to mount the (new) cartridge assembly 200 to the base 100 (or the water purifier housing), the filter cartridge assembly 200 is fed into the expansion cylinder by a handle or by directly holding the cylindrical barrel of the cartridge assembly 200. The inside of the cylinder 300 is supported. Then, the filter cartridge assembly 200 is continued to be pushed toward the base 100. The insertion end 1 of the cartridge assembly 200 is opened and passed by the first inclined surface 31, and is reset to the locked position after the blocking portion 12 passes the rear engaging assembly 6. The insertion end 1 is locked to complete the installation work of the filter element assembly 200.

Of course, during the insertion process, when the handle is in the upright state (in the second rotational position), the pushing surface 8 of the handle can also directly push the support cylinder to move toward the base 100, and the engaging component 6 is removed from the second inclined surface 13 The locking position is driven to the release position, ensuring that the blocking portion 12 of the insertion end 1 passes through the engagement opening. Further, the force receiving member 3 and the expansion member 4 in this embodiment can also function as an unlocking mechanism, and it is not necessary to provide the first slope 31 in the above embodiment.

Please refer to Figure 17 to Figure 27. A filter cartridge assembly replacement structure is provided in the embodiment of the present application, comprising: a filter cartridge assembly 200, a base 100 for mounting the filter cartridge assembly 200, and a lock for locking the filter cartridge assembly 200 on the base 100 A mechanism, an unlocking member 40 for opening the locking mechanism.

Wherein, the filter element assembly 200 is provided with a force receiving member 3 for receiving a force applied by a user. The force receiving member 3 has a first position and a second position by an action. As shown in FIGS. 17 and 19, FIG. 17 is a schematic view showing a state in which the force receiving member 3 is attached to the susceptor 100 when it is in the first position. FIG. 19 is a schematic view showing a state in which the filter element assembly 200 is inserted into the base 100 when the force receiving member 3 is in the second position.

When the force receiving member 3 is moved from the first position to the second position, the unlocking member 40 can be pushed to open the locking mechanism. The filter element assembly 200 can be inserted into the base 100 in a state where the force receiving member 3 is in the second position until being locked by the locking mechanism.

The force receiving member 3 has a first position and a second position through the action, and the action form may be rotation, translation, or even flipping. The force applied by the force receiving member 3 may be a turning force or a helium pressure. Preferably, the force receiving member 3 is rotatable about an axis of rotation.

The second rotational position.

In the present embodiment, the base 100 is mounted for the cartridge assembly 200. The susceptor 100 can be moved or operated. For example, the base 100 can be actuated during the unlocking mechanism. Of course, the base 100 preferably remains stationary in this embodiment.

The locking mechanism can be located on the base 100 or on the filter element assembly 200, which is not limited in this application. In this embodiment, the base 100 and the locking mechanism can refer to the base 100 and the locking mechanism in the above embodiments, which are not described in this embodiment.

The unlocking member 40 can unlock the locking mechanism. The unlocking member 40 has a different unlocking structure depending on the locking form of the locking mechanism. The unlocking member 40 can refer to the distracting member in the above embodiment. Of course, the unlocking member 40 can be further configured to cooperate with the force receiving member 3 to maintain the convenience of the user to install and remove the filter element assembly 200.

The filter element assembly replacement structure provided in this embodiment is provided with the force receiving member 3, which is convenient for the user to operate the filter element assembly 200 through the force receiving member 3. When the filter element assembly 200 is disassembled, the user can apply force to the force receiving member 3 to move it from the first position to the second position, which is convenient for disassembly. When the filter element assembly 200 is installed, the filter element assembly 200 can be inserted into the base 100 in a state where the force receiving member 3 is in the second position until being locked by the locking mechanism, so that even if the force receiving member 3 is in the first In the two-position state, the user can still mount the filter element assembly 200 to the base 100 without changing the state of the force receiving member 3, which is convenient for the user to operate.

The force receiving member 3 is provided with a pushing portion 50. During the movement of the force receiving member 3 from the first position to the second position, the pushing portion 50 can push the unlocking member 40 to form an unlocking action, thereby unlocking the locking mechanism. In this embodiment, in the rotation from the first position to the second position, the pushing portion 50 is pushed to move along the length direction of the cartridge assembly 200, so that the unlocking member 40 is moved toward the base 100, inserted into the locking mechanism, and locked. The organization unlocked to open.

Specifically, the unlocking member 40 is provided with a receiving surface 61 that cooperates with the pushing portion 50. The receiving surface 61 can be a flat surface. The pushing portion 50 is engaged with the receiving surface 61 to push the unlocking member 40. The receiving surface 61 is located at one end of the unlocking member 40 away from the base 100.

The pushing portion 50 is in contact with the receiving surface 61 when the first position is moved to the second position, thereby pushing the unlocking member 40 to open the locking mechanism. Wherein, in order to avoid interference or excessive interference between the force receiving member 3 and the unlocking member 40 when the force receiving member 3 is in the second position, the force receiving member 3 is in the second position, the filter element assembly 200 is At least a portion of the pushing portion 50 can be moved from one side of the receiving surface 61 to the other side of the receiving surface 61 when the base 100 is inserted.

As shown in Figure 19 and Figure 20. When the force receiving member 3 is in the second position, at least a portion of the pushing portion 50 can protrude into the unlocking member 40 and the filter element assembly 200 when the filter element assembly 200 is inserted into the base 100 between. When at least a portion of the pusher 50 extends between the unlocking member 40 and the cartridge assembly 200, the pusher 50 is allowed to radially expand the unlocking member 40 as it moves.

In order to ensure that the pushing portion 50 is in contact with the receiving surface 61, the locking mechanism can be smoothly unlocked, and the filter element assembly 200 can be unloaded from the base 100. When the force receiving member 3 is rotated from the second position to the first position, part of the pushing portion 50 can be removed from between the unlocking member 40 and the filter element assembly 200. Wherein, when the force receiving member 3 is in the first position, the pushing portion 50 may be entirely located on the upper side of the receiving surface 61 and not in contact with the receiving surface 61.

When the force receiving member 3 is in the first position, the pushing portion 50 is located outside the unlocking member 40. The pushing portion 50 is not in contact with the receiving surface 61. When the force receiving member 3 is gradually moved from the first position to the second position, the pushing portion 50 gradually contacts the receiving surface 61, and gradually pushes the unlocking member 40 toward the base 100, thereby unlocking and unlocking the locking mechanism.

As shown in Figure 17 and Figure 18. When the force receiving member 3 is in a state of not being inserted into the base 100, and is located in the second position, the end portion 51 of the pushing portion 50 may be inserted between the unlocking member 40 and the filter element assembly 200, and the unlocking member 40 is for the pushing portion 50. Movement does not create an obstacle. Thereby, the user can operate the filter element assembly 200 with the force receiving member 3 in the second position, which is convenient for the user to operate until the filter element assembly 200 is completely mounted on the base 100 without the user having to remove the filter element assembly 200 from the second position during the installation process. Change to the first location. Then, the user can move the force receiving member 3 from the second position to the first position, so that the pushing portion 50 is removed from the unlocking member 40 and the filter element assembly 200, so as to facilitate the subsequent removal of the filter element assembly 200 from the base 100. .

When the user needs to take out the filter element assembly 200, the force component is urged from the first position to the second position, and the pushing portion 50 is in contact with the receiving surface 61. As the force-bearing component gradually approaches the second position, the pusher 50 progressively pushes the unlocking member 40 toward the base 100 through the receiving surface 61 until the locking mechanism is unlocked. Finally, the user removes the filter element assembly 200 from the base 100 by the force receiving member 3 located at the second position to complete the removal of the filter element assembly 200.

Please continue to refer to Figures 17 through 25. In this embodiment, the filter element replacement structure may further include a plunge structure. The cutting-in structure is configured to cause the pushing portion 50 to cut into contact with the receiving surface 61 when the force receiving member 3 is rotated from the first position to the second position. By cutting into the structure, it is possible to prevent the pushing portion 50 from entering between the unlocking member 40 and the filter element assembly 200 when it is rotated to the second position, and cannot contact the receiving surface 61, thereby ensuring successful unlocking.

Specifically, the cutting structure may include a blocking wall 62 disposed at an end of the unlocking member 40 away from the base 100. The receiving surface 61 is located outside the blocking wall 62. One end of the barrier wall 62 in the circumferential direction is a cut-in end 63 whose outer diameter does not exceed the inner diameter of the pushing portion 50. When the force receiving member 3 is in the first position, the pushing portion 50 is located on the side of the blocking wall 62 away from the base 100. When the reader faces FIGS. 17 and 18, the pushing portion 50 is positioned above the barrier wall 62.

When the force receiving member 3 is rotated from the second position to the second position, the pushing portion 50 first comes into contact with the cutting end 63, and the one end of the blocking wall 62 in the circumferential direction has an outer diameter that does not exceed the inner diameter of the pushing portion 50. The end 63 is cut so that the pushing portion 50 is cut along the outside of the cutting end 63 to avoid cutting into the inside of the blocking wall 62. As the force receiving member 3 gradually approaches the second position, the pushing portion 50 gradually comes into contact with the receiving surface 61 to push the unlocking member 40.

As shown in Figure 25. The receiving surface 61 and the barrier wall 62 form a stepped structure. The receiving surface 61 is located outside the blocking wall 62 and extends in the same direction as the blocking wall 62. The extension length of the barrier wall 62 may be the same as the extension length of the receiving surface 61. The receiving surface 61 can be substantially a curved surface. Correspondingly, the blocking wall 62 can also have a substantially arc-shaped structure.

As shown in Figure 25. The barrier wall 62 also has a spacer 64. At least a portion of the push portion 50 can extend between the spacer portion 64 and the filter cartridge assembly 200. The inner diameter of the incision end 63 gradually increases as it extends toward the spacer portion 64. The gap distance between the spacer 64 and the cartridge assembly 200 is greater than the gap distance between the incision end 63 and the cartridge assembly 200, so that the pushing portion 50 can be inserted into the spacer when moving toward the base 100 in the second position. 64 is between the filter element assembly 200.

In the present embodiment, the force receiving member 3 includes a handle rotatably mounted to the filter element assembly 200. For the convenience of the user, the handle can be a semi-circular handle. The handle is gradually erected when rotated from the first position to the second position. One end of the handle is respectively provided with one pushing portion 50. The cylinder 41 is provided with two corresponding receiving faces 61 and a blocking wall 62.

The pushing portion 50 includes a pushing surface 8 disposed on the force receiving member 3 to rotate about an axis of rotation. The pushing surface 8 is a curved surface, in particular a curved surface, so that the pushing surface 8 can push the unlocking member 40 toward the base 100 when the pushing portion 50 is rotated about the pivoting shaft 9.

When the force receiving member 3 is rotated from the first position to the second position, the distance between the contact portion of the pushing surface 8 and the receiving surface 61 and the rotation axis gradually increases. In order to facilitate insertion of the pushing portion 50 into the inner side of the partition portion 64, the outer diameter of the end portion 51 of the pushing portion 50 is smaller than the outer diameter of the other portion. As shown in Fig. 21, the end portion 51 of the pushing portion 50 is made smaller in thickness. Of course, in other embodiments, the end portion 51 of the pushing portion 50 may also be an inner buckle structure that is curved toward the inner side. As such, when the cartridge assembly 200 is installed, only the end portion 51 of the pushing portion 50 is inserted into the inside of the spacer portion 64, and the cartridge assembly 200 is continuously pushed toward the base 100.

It is convenient for the user to install the filter element assembly 200 in consideration of avoiding excessive interference of the unlocking member 40 with the pushing portion 50 during the installation and removal of the filter element assembly 200. An end of the unlocking member 40 away from the base 100 is provided with an elastic structure. The elastic structure is elastically movable in a radial direction near an end of the force receiving member 3. The receiving surface 61 and the cutting structure are disposed at an end of the elastic structure adjacent to the force receiving member 3.

With the elastic structure, when the pushing portion 50 is inserted between the filter element assembly 200 and the elastic structure, the longer the portion into which the pushing portion 50 is inserted, the elastic structure can be expanded outward in the radial direction, thereby facilitating the insertion of the pushing portion 50, Avoiding the formation of a barrier to the pusher 50 facilitates the user to mount the cartridge assembly 200 in place. When the cartridge assembly 200 is disassembled, the pushing portion 50 is moved to the second position, and the pushing portion 50 is gradually cut into the upper side of the receiving surface 61 (the side away from the base 100) through the cutting end 63. At this time, the elastic structure can be contracted radially inward, so that the pushing portion 50 can smoothly match the receiving surface 61, and the unlocking member 40 is gradually pushed to open the locking mechanism.

The unlocking member 40 includes a cylinder 41 mounted on the base 100 and sleeved outside the filter cartridge assembly 200 (refer to the structure of the cylinder 41 in the above embodiment). The elastic structure includes a card 60 disposed on the barrel 41. Corresponding to the two pushing portions 50 on the semicircular handle, the cylinder 41 is provided with two corresponding cards 60.

The card plate 60 is provided with a gap 45 between the two sides in the circumferential direction and the cylindrical body 41. In order to prevent the interference pushing portion 50 from rotating about the pivot shaft 9, the spacing gap 45 has an opening portion away from the end of the base 100. The circumferential width gradually decreases as the opening portion extends toward the base 100. The card board 60 can be fixedly connected to one end of the cylinder body 41 away from the base 100. Preferably, the card board 60 and the barrel 41 are integrally formed.

In order to have a better elastic resetting capability and to provide a corresponding receiving surface 61. At least a portion of the card 60 has a thickness greater than a wall thickness of the barrel 41. Further, the card board 60 is provided with a connecting portion close to the base 100 and a carrying portion away from the base 100. The width of the connecting portion in the circumferential direction is smaller than the width of the bearing portion in the circumferential direction. The receiving surface 61 and the blocking wall 62 are located at the upper end of the carrying portion.

In this embodiment, the filter element replacement structure may further be provided with a guiding structure. The guiding structure is used for the pushing portion 50 and the spacing portion 64 to be aligned along the direction of the filter element assembly 200. By providing the guiding structure, the user does not need to align the pushing portion 50 with the spacing portion 64 of the card board 60 when the filter element assembly 200 is installed, which is convenient for the user to operate.

In order to facilitate guiding of the filter element assembly 200, the side wall of the filter element assembly 200 is provided with a guiding protrusion 201. The guide projection 201 is preferably a cylindrical projection, although other configurations are not limited in this application. The number of guiding protrusions 201 is preferably one

The guide structure includes a guide surface 42 provided on an inner wall of the cylindrical body 41 and a guide through hole 43 penetrating the cylindrical wall of the cylindrical body 41. The guide surface 42 extends spirally from an end remote from the base 100 toward an end adjacent to the base 100. The guiding surface 42 opens into the guiding through hole 43 near one end of the base 100. The guiding surface 42 is configured to receive the guiding protrusion 201 to guide the guiding protrusion 201 into the guiding through hole 43. The guide through hole 43 extends along the length direction of the cartridge assembly 200.

The lower end of the guide surface 42 (near the end of the base 100) leads to the through hole 43. The guide through holes 43 have portions on both sides of the guide surface 42. An observation hole may be provided in the cylinder 41 to observe whether or not the guide projection 201 is placed on the guide surface 42. When the guide projection 201 is placed on the guide surface 42, the guide projection 201 moves along the guide surface 42 until it enters the guide passage under the action of the user's thrust. When the guide projection 201 enters the guide passage, the push portion 50 is aligned with the spacer portion 64. Continuing to push the cartridge assembly 200, the pusher 50 is inserted between the card 60 and the cartridge assembly 200 until the locking mechanism locks the insertion end 1 of the cartridge assembly 200 for installation.

In order to ensure that the filter element assembly 200 can continue to move toward the base 100 after entering the guide channel 201, the filter element assembly 200 is installed. Along the longitudinal direction of the filter element assembly 200, the distance between the receiving surface 61 and the lower end of the guiding surface 42 (near the end of the base 100) is smaller than the pushing portion 50 is located at the second force receiving member 3 The distance from the guide projection 201 in the positional state.

The inner wall of the cylinder 41 is provided with at least one guiding surface 42, and the angle of the guiding surface 42 spirally extends is an integral multiple of 180 degrees. As shown in FIG. 26, two guide faces 42 extending at an angle of 180 degrees are symmetrically disposed on the inner wall of the cylindrical body 41. Therefore, the user does not need to pay attention to the position of the guiding protrusion 201, and the user only needs to insert the filter element assembly 200 into the base 100, which is very convenient for the user to operate. Of course, in other embodiments, the guide surface 42 may also be a guide surface 42 having an extension angle of 360.

It should be noted that, in the embodiment of the present application, one of the bases 100 may be moved away from the base 100, and one of the bases 100 may be moved toward the base 100, or may be regarded as moving downward. The "up and down" direction may correspond to the orientation of the reader as shown in FIG. 17 or FIG. 19, but is not limited by the actual placement state.

Of course, the embodiments of the present application are not limited to the above embodiments. In a further embodiment, at least part of it can also be moved outside the receiving surface 61 to the side of the receiving surface 61 close to the base 100. In this embodiment, the pusher 50 can be allowed to squeeze the unlocking member 40 toward the cartridge assembly 200 as it moves (also understood to be radially compressed). Correspondingly, the plunge structure is arranged opposite to that of the embodiment shown in Fig. 25, wherein the receiving surface 61 is located inside the blocking wall 62 and the spacing portion 64 is smaller relative to the inner diameter of the incision end 63.

Please refer to Figure 28 to Figure 31. In another embodiment, the force receiving member 3 is provided with a pushing portion 50 for pushing the unlocking member 40. The pushing portion 50 has a switchable push position and a release position. When the pushing portion 50 is in the release position, the force receiving member 3 does not interfere with the unlocking member 40. When the pushing portion 50 is in the release position, the pushing portion 50 can push the unlocking member 40 to open the locking mechanism.

Further, the filter element assembly 200 can be inserted into the base 100 in a state where the force receiving member 3 is located at any position between the first position and the second position until being locked by the locking mechanism. Thus, the user can install the filter element assembly 200 in place without paying attention to the position of the force receiving member 3, which is convenient for the user to install.

Further, when the pushing portion 50 is in the release position, it does not rotate together with the force receiving member 3. The pushing portion 50 rotates together with the force receiving member 3 in the pushing position. The user can apply the pushing portion 50 from the first position to the second position after the pushing member 50 is switched from the releasing position to the pushing position when the force receiving member 3 is in the first position, thereby moving the filter element assembly 200 from the first position. The base 100 is removed.

In the present embodiment, the pushing portion 50 is switched between the push position and the release position by the radial movement. Wherein, the inner diameter of the pushing portion 50 at the releasing position is larger than the inner diameter of the pushing portion. That is, the radial gap width between the pushing portion 50 and the cartridge assembly 200 when the pushing portion 50 is in the release position is greater than the radial gap width between the pushing portion 50 and the cartridge assembly 200 when the pushing portion 50 is in the pushing position. Thus, when the cartridge assembly 200 is inserted into the base 100, the pusher 50 is in the release position, regardless of whether the force member 3 is in the first position or the second position, or even anywhere between the first position and the second position. Neither affects the insertion of the cartridge assembly 200 into the base 100 until it is locked by the locking mechanism.

The pushing portion 50 is attached to both ends of the handle. The pushing portion 50 is rotatably mounted on the pivot shaft 9. When the pushing portion 50 is in the pushing position, the force receiving member 3 can drive the pushing portion 50 to rotate about a rotation axis. The pusher 50 is movable along the axis of rotation to switch between the push position and the release position.

In a possible embodiment, the pushing portion 50 has an insertion portion 54 having a inserted portion 55 (such as a loop sleeve as shown in FIGS. 30 and 31) sleeved on the pivot shaft 9, and the inserted portion 55 can be An insertion hole is provided, and the insertion portion 54 may be an insertion protrusion that can be inserted into the insertion hole. When the pushing portion 50 is in the releasing position, the insertion portion 54 moves outward along the pivot shaft 9 and is removed from the insertion hole of the inserted portion 55. Thus, the rotation linkage between the handle and the pushing portion 50 cannot be achieved, and the pushing portion 50 does not follow the handle. Turn. The pushing portion 50 is pushed radially inward, and the insertion portion 54 of the pushing portion 50 is inserted into the inserted portion 55, and the handle and the pushing portion 50 are interlocked, and the handle can drive the pushing portion 50 to rotate. In this manner, the handle is rotated to the second position, the locking mechanism is unlocked, and the filter cartridge assembly 200 is removed.

In order to simplify the user's operation, the cartridge assembly replacing structure may further be provided with an elastic member 70 that applies an elastic force to the pushing portion 50 to move toward the release position. The elastic member 70 includes a spring that is sleeved on the pivot shaft 9. The elastic member 70 can ensure that the pushing portion 50 is in the release position when the filter element assembly 200 is not required to be unlocked, thereby avoiding the erroneous unlocking of the filter element assembly 200.

See Figure 1 through Figure 31. A water purifier is further provided in the embodiment of the present invention, comprising: the filter element assembly replacing structure according to any one of the embodiments or the embodiments. Specifically, the water purifier may have a plurality of filter cartridge assemblies 200. The base 100 of the cartridge assembly replacement structure may form a water purifier housing. Of course, the support cylinder 300 may also be part of the water purifier housing.

In other embodiments, the water purifier housing is provided with a plurality of bases 100, and the plurality of bases 100 may be a unitary structure, and each of the bases 100 is correspondingly mounted with a filter element assembly 200. The water purifier housing is provided with a plurality of receiving slots; each receiving slot corresponds to an insertion hole 15 leading to a base 100. The plurality of filter cartridge assemblies 200 can be mounted in the receiving slots in one-to-one correspondence and inserted into the corresponding bases 100.

In order to improve the convenience of replacement of the filter-carrying mechanism, a filter cartridge mounting mechanism is proposed in the present application. FIG. 32 is a schematic structural view of the filter cartridge mounting mechanism before installation according to the embodiment of the present invention, as shown in FIG. The filter housing mounting mechanism may include a fixing mechanism 1 including a fixing base 11 , a rotating member 12 disposed on the fixing base 11 and rotatable relative to the fixing base 11 , and the rotating member 12 having the first engaging portion Portion 121; cartridge loading mechanism 2, the cartridge receiving mechanism 2 has a second engaging portion 21 that matches the first engaging portion 121, and the second engaging portion 21 of the cartridge receiving mechanism 2 can be loaded into the rotating member In the first engaging portion 121 of 12.

The filter cartridge mounting mechanism in the present application is provided with a rotating member 12 on the fixing base 11 which is rotatable relative to the fixed seat 11. When the filter receiving mechanism 2 needs to be installed, the second filter cartridge receiving mechanism 2 having the filter element is provided. The engaging portion 21 is inserted into the first engaging portion 121 of the rotating member 12, the second engaging portion 21 is engaged with the first engaging portion 121, and the filter receiving mechanism 2 is rotated to enable the filter element to be loaded. The mechanism 2 drives the rotating member 12 to rotate, thereby rotating the filter receiving mechanism 2 to a preset working position. When the filter-carrying mechanism 2 needs to be replaced, the filter-carrying mechanism 2 is rotated in the opposite direction, and the filter-carrying mechanism 2 drives the rotating member 12 to rotate, so that the filter-carrying mechanism 2 is rotated to the first engaging portion 121 and the second card. The position where the joint portion 21 can be separated, and then the second engaging portion 21 of the filter element receiving mechanism 2 is detached from the first engaging portion 121 of the rotating member 12, thus completing the disassembling operation of the filter element receiving mechanism 2, and finally By repeating the process of installing the filter-carrying mechanism 2, the new filter-carrying mechanism 2 can be mounted in the fixing mechanism 1.

The filter cartridge mounting mechanism in the present application realizes the relative rotation between the cartridge receiving mechanism 2 and the fixing base 11 by the rotating member 12 which can rotate itself. Therefore, when the cartridge receiving mechanism 2 is installed, the user only The second engaging portion 21 of the filter-carrying mechanism 2 can be mounted in the first engaging portion 121 of the rotating member 12, and then the filter-carrying mechanism 2 can naturally occur with the fixed seat 11 under the action of the self-weight and the rotating member 12. Relative rotation. Compared with other existing detachable filter cartridge housing 22 mounting mechanisms, the user does not need to accurately mount the filter cartridge mounting mechanism 2 into the sliding rail on the fixed seat 11 during installation, so that the cartridge loading mechanism 2 Rotate by sliding the track.

In order to better understand the cartridge housing mounting mechanism of the present application, it will be further explained and explained below. As shown in FIG. 32, the cartridge housing mounting mechanism may include a fixing mechanism 1 and a cartridge receiving mechanism 2. The fixing mechanism 1 is used for loading the filter-carrying mechanism 2, and the filter-carrying mechanism 2 may include a fixing base 11, a rotating member 12 disposed on the fixing base 11 and rotatable relative to the fixed seat 11. The fixing base 11 can include a body 114 and a limiting member 115 connected to the body 114. The rotating member 12 is disposed on the body 114, and the limiting member 115 is used for resisting the rotating member 12 to limit the rotating member 12, thereby preventing The rotating member 12 is disengaged from the fixed seat 11 while being able to rotate the rotating member 12 on the fixed seat 11. A first engaging portion 121 is formed on the rotating member 12, and the first engaging portion 121 is engaged with the second engaging portion 21 of the filter receiving mechanism 2, so that the rotating member 12 and the filter receiving mechanism 2 are The transmission can take place.

As shown in FIG. 32, the cartridge receiving mechanism 2 may have a second engaging portion 21 matching the first engaging portion 121, and the second engaging portion 21 of the cartridge receiving mechanism 2 can be loaded into the rotating member 12. In the first engaging portion 121. In one embodiment, as shown in FIG. 32, the cartridge receiving mechanism 2 may include a housing 22 for receiving the filter cartridge and a rotating mechanism 23 disposed on the housing 22, and the rotating mechanism 23 is shared with the housing 22. The second engaging portion 21 is formed. The second engaging portion 21 formed by the rotating mechanism 23 and the housing 22 can be engaged with the first engaging portion 121 and can rotate relative to the first engaging portion 121 around the fixed seat 11. In another embodiment, the cartridge receiving mechanism 2 may include: a housing 22 for receiving the filter cartridge and a rotating mechanism 23 disposed on the housing 22, the rotating mechanism 23 separately forming the second engaging portion 21, the shell The body 22 can be connected to the rotating mechanism 23 by plugging or other connection to achieve the fixation between the two, and can not be easily separated. Thus, the second engaging portion 21 formed on the rotating mechanism 23 can be combined with the second engaging portion 21 A latching portion 121 is relatively rotated about the fixed base 11. In still another embodiment, the cartridge receiving mechanism 2 may include: a housing 22 for receiving the filter cartridge and a rotating mechanism 23 disposed on the housing 22, and the second engaging portion 21 is separately formed on the housing 22, The rotating mechanism 23 is connected to the housing 22 by plugging or other connection to achieve the fixing therebetween. Thus, the second engaging portion 21 formed on the housing 22 can be coupled to the first engaging portion 121. Relative rotation occurs around the mount 11. In both of the above embodiments, since the rotating mechanism 23 is fixedly coupled to the housing 22, when one of the components is rotated, the other member can be rotated.

As shown in FIG. 32, the fixing base 11 has a receiving portion 13 on which the rotating member 12 is mounted. The receiving portion 13 may be formed on the body 114 of the fixing base 11 or may be formed on the limiting member 115 of the fixing base 11. In other possible manners, the body 114 of the fixing seat 11 and the limiting member 115 can jointly form the receiving portion 13. The rotating member 12 is disposed in the accommodating portion 13. When the cartridge receiving mechanism 2 is mounted in the fixing base 11, since the outer contour of the rotating member 12 is substantially circular, the rotating member 12 can disperse the weight of the filter receiving mechanism 2 to The lower portion of the accommodating portion 13 of the lower fixing base 11 of the rotating member 12 is configured to prevent cracking or breakage of a portion of the fixing base 11 due to the concentrated force from receiving the weight of the entire filter-carrying mechanism 2. The receiving portion 13 has a notch 131. The second engaging portion 21 can be removed from the first engaging portion 121 of the rotating member 12 or inserted into the first engaging portion 121 of the rotating member 12 through the notch 131, so that the fixing mechanism 1 is fixed. Separated from or installed with the filter holder mechanism 2.

In a preferred embodiment, the first engaging portion 121 can extend in a straight line direction, and the second engaging portion 21 also extends in a linear direction. Thus, the second engaging portion 21 of the cartridge receiving mechanism 2 is along a straight line. The direction is inserted into the first engaging portion 121 of the rotating member 12. Since the filter-carrying mechanism 2 has a filter element and water, the weight thereof is relatively large, and the user is laborious in the process of disassembling and installing the filter-carrying mechanism 2, in the embodiment, the user can directly adopt the filter-carrying mechanism 2 The second engaging portion 21 inserts or pulls out the first engaging portion 121 of the rotating member 12 in a linear direction, thereby greatly simplifying the installation or disassembly process of the filter receiving mechanism 2, and improving the user's disassembly and installation of the filter receiving mechanism 2. Convenience. The first engaging portion 121 can be a sliding slot. When the second engaging portion 21 is engaged with the sliding slot, the second engaging portion 21 can rotate the rotating member 12 through the sliding slot when the rotating mechanism 23 rotates.

In a more preferred embodiment, the second engaging portion 21 of the cartridge receiving mechanism 2 can insert or pull out the first engaging portion 121 of the rotating member 12 in the horizontal direction. In the above manner, the user can more easily insert or remove the filter-carrying mechanism 2 in the horizontal direction from the fixing mechanism 1 during the process of installing or removing the filter-carrying mechanism 2, in the process, the user It is not necessary to lift or lower the filter receiving mechanism 2, and it is not necessary to consider the angle of lifting or lowering the filter receiving mechanism 2.

33 is a schematic view of the cartridge housing mounting mechanism in a first position according to an embodiment of the present invention, and FIG. 34 is a schematic view showing the cartridge housing mounting mechanism in a second position according to an embodiment of the present invention, as shown in FIGS. 33 and 34. The filter housing mounting mechanism has at least two positions. As shown in FIG. 32, when the cartridge receiving mechanism 2 is rotated to the first position relative to the fixing mechanism 1, the first engaging portion 121 faces the notch 131, and the second engaging portion 21 can be inserted into the first engaging portion 121. As shown in FIG. 34, when the filter-carrying mechanism 2 is rotated to the second position relative to the fixing mechanism 1, the first engaging portion 121 is offset from the notch 131, and the filter-carrying mechanism 2 is mounted on the fixing mechanism 1, and the filter-carrying mechanism 2 Cannot be separated from the fixed mechanism 1.

As shown in FIG. 32, the fixing base 11 further has a limiting portion 113. The partial rotating member 12 is located in the limiting portion 113, so that the rotating member 12 rotates within a preset range. For example, when the cartridge receiving mechanism 2 is rotated relative to the fixing mechanism 1 to the first position, the upper end of the limiting portion 113 limits the rotating member 12 against the side of the rotating member 12 to prevent further rotation thereof, thereby The rotating member 12 is held in the first position. When the filter-carrying mechanism 2 is rotated relative to the fixing mechanism 1 to the second position, the lower end of the limiting portion 113 limits the rotating member 12 against the other side of the rotating member 12 to prevent further rotation thereof, thereby causing the rotating member 12 remains in the second position.

As shown in FIG. 32, the limiting member 115 has a third guiding portion 1151. The third guiding portion 1151 can abut the second engaging portion 21 to slide the second engaging portion 21 into the first engaging portion 121. In the present embodiment, when the cartridge receiving mechanism 2 is attached to or removed from the fixing mechanism 1 , the second engaging portion 21 of the cartridge receiving mechanism 2 and the third guiding portion on the limiting member 115 can be used. 1151 is abutted, under the guiding action of the third guiding portion 1151, the filter-carrying mechanism 2 can directly slide into the first engaging portion 121 of the rotating member 12 against the third guiding portion 1151, or directly from the rotating member 12 The stopper 115 is slid out along the third guiding portion 1151 in the one engaging portion 121. Since the third guiding portion 1151 on the limiting member 115 can support the filter-carrying mechanism 2 upward, on the one hand, the filter-carrying mechanism 2 can be easily loaded and unloaded, and on the other hand, it bears a part of the weight of the filter-carrying mechanism 2. Thereby, the effort required by the user to hold the filter cartridge mechanism 2 is alleviated.

As shown in FIG. 32 and FIG. 34, the fixing base 11 has a waterway interface 112.
