Description

Method for inserting rotary lifting linkage handle device and filter liner of water purifier and filter liner

Technical Field

The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.

Background

As the consumptive material of purifier, filter courage after using a period, need change the filter courage. However, with popularization of water purifiers, defects and shortcomings of the water purifiers in application are gradually exposed: the water purifier with middle and low price mostly adopts an open type liner configuration bare metal mode. The shell with the inner liner is hung below the machine base, and although the shell can be reused, the problems of difficult replacement of the inner liner, difficult cleaning of the filter cavity and the like exist: the water purifier with the lower open filter cartridge is usually directly placed in a kitchen cabinet through a shell with a built-in liner, the water purifier is required to be taken out and put on the air when the liner is replaced, and then a special filter liner wrench is sleeved on the shell from bottom to top and is forcibly rotated to loosen the threaded connection of the shell and the machine base to detach the shell. After the new liner is replaced, the shell with the liner is tightly screwed below the machine base, and the whole operation process is very labor-intensive. Because the water purifier with water is heavy, and the built-in filter liners in the open filter cartridge are all poured out together with the water after the filter cartridge is detached, the water pollution treatment is very troublesome. Moreover, because the liner is placed in the filter cylinder, water leakage is easy to occur due to a little carelessness during replacement. For the horizontal water purifier, the use is very convenient: can be placed on the table top of a kitchen cabinet or in the cabinet; the machine is only required to be directly placed at the using position, and the punching hanging machine is not required. Because the filter liner is positioned above the machine base, the filter liner is convenient to replace, and the time and the labor are saved relatively. However, the biggest problem of adopting the seat type water purifier structure is that the machine operation surface is small, the display component and the operation control device can only be arranged on the side elevation of the machine, the top surface is used for replacing the filter liner, and the water passing control component can be placed in no place. Since the water purifier has a limited length and width, which is generally less than 500 mm×200 mm×450 mm, the placement of the display control device on the machine side elevation will affect the number of filter liners to be placed. When the closed filter liner is used, water in the filter liner can flow out from the water gap of the filter liner to pollute the surrounding environment when the filter liner is replaced because the water gap of the filter liner faces downwards. The water in the filter element at the front and rear stages of the replaced filter element is also discharged from the water inlet and outlet pipelines of the corresponding machine seat of the detached filter element until the water level in the water purifier is balanced again, so that the seat type water purifier with the lower machine seat has the characteristic of convenient extraction of the filter element, but the mode is rarely adopted. Because the environment for placing the water purifier is generally poor, the leaked water flow rate in the process of replacing the filter liner is too fast to be removed, so that the operation is inconvenient, and the cabinet is soaked and even the cabinet plate is damaged. Considering that the replacement of the filter liner always accompanies the whole use process of the water purifier, the related problems caused by the replacement of the filter liner and the cleaning of the filter channel can frequently and repeatedly occur. On the other hand, the replacement of the filter liner of the water purifier requires professional personnel to go to the gate for service, which is labor-consuming and time-consuming and increases the expense of consumers. The above-mentioned drawbacks and disadvantages make it difficult to obtain a water purifier that is more widely popularized.

Detailed Description

Example 1. In fig. 1, a handle device with a rotation and lifting linkage structure comprises an inserting handle 1 provided with an upper limit structure 11 and an inserting pipe, an inserting rod 2 provided with a step 21, a vertical elastomer, a transverse notch and a guide structure, and a lower support 4 provided with a guide extrusion structure 42; the inserted link 2 is arranged in the insertion tube of the insertion handle 1, two ends of the vertical elastic body are respectively in contact fit with the insertion handle 1 and the inserted link 2, and the inserted link 2 is controlled in an upper limit through the upper limit structure 11. The lower support piece 4 is connected with the lower part of the plugging handle 1 integrally to form a movable cavity 16 with a transverse notch and a guide structure and communicated with the cannula; the movable cavity 16 is a cavity structure formed by combining a transverse notch 17 and a guide structure which are arranged at the lower part of the plugging handle 1 with the lower support piece 4, or a cavity structure formed by combining related structures which are respectively arranged at the lower part of the plugging handle 1 and the lower support piece 4 and provided with the transverse notch 17 and the guide structure, or a cavity structure formed by combining a transverse notch 17 and a guide structure which are arranged on the lower support piece 4 with the lower part of the plugging handle 1; the plunger rod moves downwards from the upper limit to the lower limit of the travel under the action of the applied external force in the vertical direction.

The handle device also comprises a transverse pushing structure; the transverse pushing structure moves along the guiding structure along with the downward movement of the inserting rod 2 until the outer side end touches the transverse notch 17; the transverse pushing structure is either a rigid transverse pushing structure 27 arranged at the lower end of the inserted link or a deformation movable part 3 matched with the lower end of the inserted link, wherein:

for a rigid push-pull structure, the plunger 2 moves downward from an upper limit to a lower limit under the application of an external force. The rigid transverse pushing structure at the lower end of the inserted link 2 is directly contacted and matched with the front end of the transverse moving part which is positioned in the splicing position when the transverse moving part corresponding to the filter liner to be spliced is inserted into the transverse notch of the movable cavity, and moves to the outer side end to touch the transverse notch, so that the transverse moving part is forced to exit from the transverse notch and be positioned in the splicing position; after the applied external force is removed, the inserted link moves upwards under the action of the resilience force of the vertical elastic body, and the rigid transverse pushing structure arranged in the movable cavity returns to the position corresponding to the inserting position from the position corresponding to the position to be inserted.

The rigid transverse pushing structure 27 can be either a convex rigid transverse pushing structure (see the structure shown in fig. 4 and 5) or an 'equal diameter' structure with the inserted link, namely, the rigid transverse pushing structure is directly pushed outwards transversely by the circumferential surface of the inserted link.

In this case, as a specific example, as long as the insert rod 2 can achieve the above-mentioned function of the rigid transverse pushing structure, the rigid transverse pushing structure is considered to exist.

For the deformation movable member 3, the movable chamber 16 restricts the deformation movable member 3 placed on the lower support member 4 to be movable only in deformation along the guide structure (for example, the closed deformation movable member is deformed in the circumferential direction) but not in the direction perpendicular to the vertical face formed by the longitudinal and transverse deformation of the deformation movable member 3 (the deformation movable member 3 is not movable in the axial direction perpendicular to the transverse notch 17). The guide structure is a structure that defines the deformation movement 3.

The plug handle 1 is inserted into the filter liner vertical shaft structure 51 to be connected, the transverse moving piece 53 on the filter liner 5 to be connected is extruded by the lower end guiding extrusion structure 42 of the lower support piece 4 to the position to be connected, and moves to the plug position under the resilience force of the elastic piece 54 after the transverse notch 17 of the plug handle 1 corresponds to the filter liner side wall hole structure 55 to be connected, the front end of the transverse moving piece 53 is inserted into the transverse notch 17 of the plug handle 1, the plug handle 1 and the filter liner 5 to be connected are in rotary and lifting linkage, and the corresponding deformation movable piece 3 in the plug handle 1 is in the state corresponding to the plug position.

The insert rod 2 of the handle device moves downwards to the lower limit by the upper limit defined by the upper limit limiting structure 11 under the action of external force exerted in the vertical direction, the lower end 25 of the insert rod is in contact fit with the upper end of the deformation movable piece 3 placed in the movable cavity 16 and in the plugging position, and horizontal component force is generated on the deformation movable piece 3 to enable the deformation movable piece 3 to generate deformation displacement in the transverse direction, namely the deformation movable piece 3 on the lower support piece 4 is forced to deform transversely (such as transversely deform along the upper surface 41 of the lower support piece 4 a) until the side end contacts the transverse notch 17, namely the lower limit of the stroke of the insert rod corresponding to the plugging position. The lateral moving member 53 of the filter element 5 to be connected is pushed by the deformation moving member 3 (horizontal component force) and moves laterally against the acting force of the elastic member 54, and the front part of the lateral moving member 53 exits the lateral notch 17 to the position to be inserted, i.e. the front end of the lateral moving member 53 exits the lateral notch 17 of the insertion handle 1.

After the applied external force is removed, the inserted link 2 moves upwards to the lower end of the step 21 positioned at the upper limit structure 11 under the action of the resilience force of the vertical elastic body, the deformed movable piece 3 positioned in the movable cavity 16 correspondingly rebounds and recovers, and the deformed state corresponding to the position to be inserted of the transverse movable piece 53 returns to the state corresponding to the position to be inserted of the transverse movable piece 53. At this time, the lateral moving member 53 is moved by the resilient force of the resilient member 54, and the front portion thereof protrudes from the side wall hole structure 55 to be in the insertion position.

The deformation moving member 3 may be a circular ring-shaped closed loop elastic structure 3a (structure shown in fig. 1), an elliptical ring-shaped closed loop elastic structure (vertical), or a diamond ring-shaped closed loop elastic structure (vertical). In addition, the elastic structure can be a herringbone open annular elastic structure (vertical).

The support structure 12 is used to support a spring 22 that is fitted over the plunger.

The upper part of the plug handle provided with an upper limit structure, a lower limit structure and a cannula and internally provided with a vertical spring adopts a two-component connection combined structure, wherein the upper limit structure 11 is used for carrying out upper limit control on the plug rod 2, and the corresponding plug rod is positioned at the upper limit position; the lower limit structure is used for carrying out lower limit control on the inserted link 2, and the corresponding inserted link is positioned at the lower limit.

In fig. 3 and 4, a handle device with a rotating and lifting linkage structure comprises an inserting handle 1 provided with an upper limit structure 11 and an inserting tube, an inserting rod 2 provided with a step 21, a vertical elastomer, a transverse notch 17, a guide structure, a lower support piece 4a and a ball 6a arranged in the guide structure. The lower support piece 4a and the lower part of the plugging handle 1 are connected integrally to form a movable cavity 16 with a transverse notch 17 and a guiding structure and communicated with the cannula. The movable cavity 16 is a cavity structure formed by combining a transverse notch 17 and a guide structure which are arranged at the lower part of the plugging handle 1 with the lower support piece 4a, or a cavity structure which is formed by combining related structures which are respectively arranged at the lower part of the plugging handle 1 and the lower support piece 4a and is provided with the transverse notch 17 and the guide structure, or a cavity structure formed by combining the transverse notch 17 and the guide structure which are arranged on the lower support piece 4a with the lower part of the plugging handle 1, and the built-in ball 6a is limited to move only along the transverse notch 17 and the guide structure; the inserted link 2 is arranged in the insertion pipe of the insertion handle 1, two ends of the vertical elastic body are respectively in contact fit with the insertion handle 1 and the inserted link 2, and the upper limit of the inserted link 2 is controlled through an upper limit structure; the plunger rod moves downwards from the upper limit to the lower limit of the travel under the action of the applied external force in the vertical direction.

The handle device also comprises a transverse pushing structure; the horizontal pushing structure moves downwards along with the inserted link 2 to the lower limit of the travel, and can only move along the guide structure until the outer side end contacts the ball 6a arranged in the guide structure to move outwards to be in contact fit with the horizontal notch; the horizontal pushing structure can be a rigid horizontal pushing structure (connected with the inserted rod) arranged at the lower end of the inserted rod 2, or can be a deformation movable piece 3 (a separate piece separated from the inserted rod) matched with the lower end of the inserted rod.

The downward moving plunger 2 or through the lower end of the rigid horizontal pushing structure 27 is directly contacted and matched with the ball 6a at the position to be inserted to force the ball 6a to move outwards along the guiding structure 17a to the position of the transverse notch 17, the front end extends outwards to form the transverse notch 17 and is inserted into the side wall hole structure 55 of the vertical shaft structure 51 of the upper end face of the filter liner 5 to be connected to the inserting position, namely the lower limit of the stroke of the plunger (as shown in fig. 4, the rigid horizontal pushing structure 27 touches the upper surface 41 of the lower supporting piece 4 a), and the horizontal pushing structure limits the ball 6a to move inwards along the transverse notch 17 and the guiding structure 17 a.

As an improvement, the outer end opening of the transverse notch guide structure 17 is smaller than the diameter of the ball 6a, so that the ball 6a is limited to be separated from the plugging handle 1, and the ball is prevented from being lost.

As an improvement, the lower support member can be provided with a downwardly inclined guide structure, so that when the transverse pushing structure moves upwards, the balls automatically move inwards to the position to be inserted along the guide structure with the inclined angle.

As a further improvement, the lower guide surfaces of the transverse notch 17 and the guide structure 17a are of an inclined surface structure with high outside and low inside. When the ball is not limited by the transverse pushing structure, the ball can automatically roll inwards along the inclined plane structure by self weight.

As a further improvement, the transverse notch 17 and the guide structure 17a are in a horn structure with small outside and large inside, so that when the ball 6a moves outwards, the front end part of the ball 6a which extends out of the transverse notch 17 and the guide structure 17a is as much as possible, and the radial plug-in fit with the filter liner inserted into the side wall hole structure 3 is facilitated.

The rigid transverse pushing structure 27 can be either a convex transverse pushing structure (as shown in fig. 4 and 5) or an 'equal diameter' structure with the inserted link, i.e. the rigid transverse pushing structure is directly pushed transversely outwards by the circumferential surface of the inserted link.

The downward moving inserted link 2 or the deformation movable part 3 which is in contact fit with the lower end 25 is indirectly in contact fit with the ball 6a at the position to be inserted, so that the ball 6a is forced to move outwards along the guide structure 17a and the transverse notch 17, the front end extends outwards to form the transverse notch 17, the insertion position is also the lower limit of the travel of the inserted link when the inserted link is inserted into the side wall hole structure on the vertical shaft structure of the filter liner to be connected, and the transverse pushing structure limits the ball 6a to move inwards along the transverse notch 17 and the guide structure 17 a.

Whether or not the transverse notch 17 limits the ball 6a to only partially extend, the sidewall aperture structure 55 on the filter cartridge to be connected has a diameter smaller than the diameter of the ball 6 a.

Under the action of external force in the vertical direction and resilience force of the vertical elastic body, the transverse pushing structure moves upwards along with the inserted rod, and the ball 6a arranged at the inserting position is in a free state capable of moving into the inserting handle 1, so that the inserting locking function between the inserting handle 1 and the filter liner 5 to be connected is lost: the horizontal component force, which generates shearing force on the rollers 6a along the insertion handle 1 and the filter liner shaft structure 51 when the insertion handle 1 is extracted, forces the balls 6a placed in the transverse notch 17 and the guide structure 17a to move inwards in the radial direction, and particularly when the guide structure 17a is provided with an inclined surface structure with high outside and low inside, the balls 6a roll into the insertion handle 1 by virtue of self weight.

Example 3. Based on the embodiments 1 and 2, the device also comprises a inserted rod locking device provided with a locking piece channel and a lateral notch structure; when the lock passage is placed on the plugging handle, the lateral notch structure part corresponding to the lock passage is placed on the plugging rod. When the lock channel is placed on the plugging handle and the plugging rod and does not affect the axial movement of the plugging rod between the upper limit and the lower limit, the lateral notch structure corresponding to the lock channel is placed on the plugging rod in whole or in part.

The inserted link locking device is either a bi-directional locking mechanism operated in both directions or a unidirectional locking mechanism operated in both directions, wherein:

for the bidirectional locking mechanism (shown in the structures of figures 1, 3 and 4), the bidirectional locking mechanism comprises a locking post, a release post and a small-diameter connecting rod; two ends of a small-diameter connecting rod arranged in the lock piece channel are respectively connected with the locking post and the release post to form a whole. The locking post transversely moves along the lock piece channel, the front end is inserted into the lateral notch structure, and the rear end is arranged in the plug handle to limit the plug rod to move upwards; the release post moves reversely until the linked locking post exits the lateral notch structure to release the limit of the inserted link. The lock piece channel of the bidirectional locking mechanism has the following three structures:

as a first type of lock passage, the structure shown in fig. 1, 2, 3, 4 and 5, the bidirectional locking mechanism comprises a locking post 15, a release post 13 and a small-diameter connecting rod 14. The lock passage comprises two opposite wall holes on the plugging handle and a transverse waist-shaped through hole 23 arranged on the plugging rod 2, and a lateral notch structure 24 arranged around the upper part of the waist-shaped through hole 23. The two ends of the small-diameter connecting rod 14 penetrating through the 23 on the inserted link 2 are respectively connected with the release post 13 and the locking post 15 through two wall holes to form a whole. The locking post 15 moves inwards along the wall hole, and the insertion rod 2 is limited to move upwards in the lateral notch structure 24 of the insertion rod 2 at the front end; the release post 13 moves inwardly along the wall aperture to the interlocked capture post 15 moves outwardly out of the lateral notch feature 24 of the plunger 2, disengaging the restriction of upward movement of the plunger 2. The small diameter link 14 in the transverse waist-shaped through hole structure does not affect the downward movement of the plunger 2.

As a second type of lock passage, a transverse notch structure (corresponding to a waist-shaped through hole structure with one side open) arranged on the inserted link and a structure corresponding to the inserted link are combined to form the lock passage, the small-diameter connecting rod 14 or all or part of the small-diameter connecting rod is positioned in the notch structure, two ends of the small-diameter connecting rod are respectively connected with the release column 13 and the locking column 15 through two wall holes of the inserted link to form a whole, and the small-diameter connecting rod 14 does not influence the axial movement of the inserted link 2 between the upper limit and the lower limit. The lateral notch structure is located on the insert rod 2, either partially or entirely. The front end or part or all of the locking post 15 inserted into the lateral notch structure is inserted into the lateral notch structure correspondingly positioned on the inserted link, and the rear end of the locking post is placed in the wall hole structure of the plugging handle to form the locking position of the inserted link.

As a third type of lock channel, the lock channel is provided on the plugging handle 1, and the lateral notch structure is simultaneously provided on the plugging handle 1 and the plugging rod 2. When the front end of the locking post 15 is inserted into the lateral notch structures on the inserted link and the plug-in handle respectively, the rear end of the locking post is placed in the wall hole structure of the plug-in handle to form the locking position of the inserted link.

The above-mentioned locking post 15, the release post 13 and the small diameter connecting rod 14 may be in a structure mode in which three members are integrally connected, a structure mode in which a connecting structure of the small diameter connecting rod 14 and the release post 13 is integrally connected with the locking post 15, or a structure mode in which a connecting structure of the small diameter connecting rod 14 and the locking post 15 is integrally connected with the release post 13. Whichever kind of structure inserted bar is adopted, the inserted bar locking device is limited and can not be separated from the inserted handle.

The wall hole of the plugging handle 1 corresponding to the release post 13 can be either a through hole structure (the plugging rod limits the movement of the locking post and the release post respectively, such as the structure shown in fig. 2 and 3) or a through hole structure with a counter bore (the plugging handle limits the release post, such as the structure shown in fig. 1, 4 and 5).

For the unidirectional locking mechanism, the unidirectional locking mechanism comprises a T-shaped locking piece with a large inner part and a small outer part, the plugging handle is arranged as a wall hole structure of a locking piece channel, the T-shaped locking piece with the large inner part and the small outer part is arranged in the wall hole structure of the plugging handle, the front end of the T-shaped locking piece is arranged on the inner side of the wall hole structure, and the rear end of the T-shaped locking piece extends out of the wall hole structure. The T-shaped locking piece transversely moves along the wall hole structure, the front end of the T-shaped locking piece is inserted into the lateral notch structure, and the rear end of the T-shaped locking piece is arranged in the wall hole to limit the axial movement of the inserted link; the T-shaped locking piece moves reversely along the wall hole structure to withdraw from the lateral notch structure of the inserted link, so that the inserted link is limited. The T-shaped locking piece can not be separated from the inserting handle due to the limitation of the wall hole structure to the front end (large end).

The present embodiment has a two-way latching mechanism mode with three latch channels, and a one-way latching mechanism is applicable to each of the following embodiments.

Example 4. On the basis of embodiments 1, 2, the vertical elastic body can be either a spring 22 or a deformation movement by transverse deformation until the lateral ends touch the transverse slits, 3, wherein for the spring, the spring is sleeved on the inserted bar and the two ends are respectively in contact fit with the inserted handle and the inserted bar, or is arranged between the inserted bar and the lower support piece and the two ends are respectively in contact fit with the rigid transverse pushing structures of the lower support piece and the inserted bar; for the deformation movable piece, the deformation movable piece is arranged between the inserted link and the lower support piece, and two ends of the deformation movable piece are respectively in contact fit with the inserting handle of the lower support piece and the inserted link.

Wherein, for the spring 22, the spring 22 can be sleeved on the inserted link 2, and the two ends of the spring are respectively contacted and matched with the inserted link 2 and the inserted link 1, as shown in the structures of figures 1 and 4; or can be arranged between the inserted link 2 and the bottom (lower supporting piece) of the inserted link 1, and the two ends are respectively contacted and matched with the bottom of the inserted link 1 and the inserted link, as shown in the structure of fig. 5.

For the deformation movable piece 3, the deformation movable piece 3 is arranged between the inserted link 2 and the bottom of the plugging handle 1, and two ends of the deformation movable piece are respectively in contact fit with the bottoms of the inserted link 2 and the plugging handle 1.

For example, a mode in which the spring 22 is fitted over the plunger 2 and both ends thereof are in contact engagement with the socket handle 1 and the plunger 2, respectively, and a mode in which the deformation movable member 3 is interposed between the plunger 2 and the bottom of the socket handle 1 and both ends thereof are in contact engagement with the plunger 2 and the bottom of the socket handle 1, respectively, are combined, wherein both the spring 12 and the deformation movable member 3 may be treated as an elastic body (as a structure shown in fig. 1), or only the spring 22 may be treated as an elastic body, and the deformation movable member 3 may be used to control the balls 6a or the traverse member 53. At this time, the deformation movable part 3 can be in contact fit with the inserted link 2 or can be in clearance with the inserted link 2, and the deformation movable part is in contact fit until being pressed and then transversely deformed in the process of moving downwards.

Alternatively, a mode (a structure shown in fig. 3) in which only the deformation movable member 3 is provided and interposed between the plunger 2 and the bottom of the plugging handle 1 and both ends thereof are respectively in contact engagement with the bottom of the plugging handle 1 and the plunger 2 may be employed. At this time, the deformation moving part 3 is not only an elastic body to play a role of elastic reset, but also a derivative 'extrusion pushing rod' to play a role of controlling the ball.

Example 5. In fig. 2, a handle device with a rotation and lifting linkage structure comprises an inserting handle 1 provided with an upper limit structure 11 and an inserting tube, an inserting rod 2 provided with a step 21 and an inclined pushing structure 26, a spring 22, a transverse notch 17, a guide structure and a lower support piece 4a, and a transverse inserting piece 6 provided with a movable matching structure 61 and a horizontal spring piece 62; the lower support piece 4a is connected with the lower part of the plugging handle 1 into a whole and forms a movable cavity 16 with a transverse notch 17 and a guide structure and communicated with the cannula; the movable cavity 16 is a cavity structure formed by combining a transverse notch 17 and a guide structure which are arranged at the lower part of the plugging handle 1 with the lower support piece 4a, or a cavity structure formed by combining related structures which are respectively arranged at the lower part of the plugging handle 1 and the lower support piece 4a and provided with the transverse notch 17 and the guide structure, or a cavity structure formed by combining a transverse notch 17 and a guide structure which are arranged on the lower support piece 4a with the lower part of the plugging handle.

The inserted link 2 is arranged in the insertion pipe of the inserting handle 1, and two ends of a spring 22 sleeved on the inserted link 2 are respectively in contact fit with the inserting handle 1 and the inserted link 2, and the upper limit of the inserted link 2 is controlled through an upper limit structure 11; the inserting rod 2 moves downwards from the upper limit under the action of the applied external force in the vertical direction, the inclined pushing structure 26 at the lower end of the inserting rod 2 is in contact fit with the moving fit structure 61 at the rear end of the transverse moving member 6 which is arranged in the movable cavity 16 and is positioned at the position to be inserted, the front end of the transverse moving member 6 is forced to extend out of the transverse notch 17 in the transverse moving mode, and the transverse moving member is inserted into the side wall hole structure 55 on the vertical shaft structure 51 of the filter liner 5 to be connected, namely, the transverse moving member is positioned at the inserting position.

The handle device also comprises a inserted rod locking device with a locking piece channel and a lateral notch structure. When the lock passage is placed on the plugging handle, the lateral notch structure part corresponding to the lock passage is placed on the plugging rod. When the lock channel is placed on the plugging handle and the plugging rod and does not affect the axial movement of the plugging rod between the upper limit and the lower limit, the lateral notch structure corresponding to the lock channel is placed on the plugging rod in whole or in part. The locking device is either a bi-directional locking mechanism or a unidirectional locking mechanism, wherein:

for a bidirectional locking mechanism (shown in the structure of figure 2), the bidirectional locking mechanism comprises a locking post, a release post and a small-diameter connecting rod; two ends of a small-diameter connecting rod arranged in the lock piece channel are respectively connected with the locking post and the release post to form a whole. The locking post transversely moves along the lock piece channel, the front end is inserted into the lateral notch structure, and the rear end is arranged in the plug handle to limit the plug rod to move upwards; the release post moves reversely to the linkage locking post to exit the lateral notch structure to release the limit of the inserted link, and after the applied external force in the vertical direction is removed, the inserted link 2 moves upwards under the action of the spring resilience force, the transverse plug connector 6 arranged in the movable cavity 16 moves back to the position to be inserted under the action of the resilience force of the horizontal spring 62, and exits from the plug connection with the side wall hole structure 55 of the vertical shaft structure 51 of the upper end face of the filter liner 5 to be connected. The lateral limit 43 is used for limiting the inner sides of the two lateral connectors 6, so as to facilitate the downward insertion of the inclined pushing structure 26. This embodiment applies equally to the three lock channel modes described in embodiment 3.

The combination of embodiments 2, 3 and 4 eliminates the horizontal spring and reduces the size of the transverse plug and return mechanism compared to embodiment 5, thereby significantly reducing the size of the plug handle.

As an improvement of the above embodiments 1 to 5, the plugging handle is provided with a non-circular section structure, i.e. a non-circular outer contour structure, such as a polygon or a regular polygon, which is in plugging fit with and rotationally linked with the inner side wall of the shaft structure of the filter liner to be plugged. The non-circular outer contour structure of the plugging handle is in plugging fit with the corresponding structure of the inner side wall of the vertical shaft structure of the filter liner to be connected and in rotary linkage mode, the corresponding outer contour structures of the corresponding non-circular section structures of the plugging handle 1 and the vertical shaft structure 4 are in plugging fit with each other and in rotary linkage, so that the stress condition of the movable plug connector for the plugging fit between the transverse notch of the two parts and the side wall hole structure is improved, and the movable plug connector is changed into rotary linkage and lifting linkage two works originally born by the movable plug connector, and is mainly used for extracting the filter liner by the plugging handle 1.

Usually, the operating handle structure is symmetrically provided with two movable rods and corresponding guide groove structures.

The operating handle structure length of the inserting handle is increased by moving and extending or swinging and extending the movable rod so as to facilitate operation.

Example 7. The filter liner matched with the handle device with the rotation and lifting linkage structure in the embodiments 2, 3, 4 and 5 comprises a filter material layer, a water inlet and a water outlet connected with two sides of the filter material layer, and a shell provided with a fastening structure, a water inlet and a water outlet and internally provided with the filter material layer; the shell is an open shell formed by sealing connection of a closed shell or a cylinder body and a cylinder cover, and the fastening device is positioned on the circumferential surface of the shell or the lower end surface of the shell; the filter liner 5 further comprises a shaft structure 51 provided with a side wall hole structure 55; the side wall hole structure 55 of the shaft structure 51 is vertically inserted and matched with the to-be-connected inserting handle 1, and the side wall hole structure 55 positioned at the outer side of the inserting handle 1 corresponds to the transverse notch 17 of the inserting handle 1 and is used for the outward movement insertion of a transverse moving piece or a ball in the inserting handle 1.

For embodiments 2, 3, and 4 (the structure shown in fig. 2), the diameter of the sidewall hole structure 55 of the shaft structure 51 is smaller than the diameter of the ball 6a, and corresponds to the transverse notch 17 of the plugging handle 1 to be plugged, so as to facilitate the insertion of the front end of the ball 6 a.

For example 5 (fig. 2 shows the structure), the side wall hole structure 55 of the shaft structure 51 corresponds to the transverse cutout 17 of the plugging handle 1 to be plugged in, so that the transverse plug 6 can be plugged in.

Example 8. The filter liner matched with the handle device with the rotation and lifting linkage structure in the embodiments 1, 3 and 4 comprises a filter material layer, a water inlet and a water outlet connected with two sides of the filter material layer, and a shell provided with a fastening structure, a water inlet and a water outlet and internally provided with the filter material layer; the shell is an open shell formed by sealing connection of a closed shell or a cylinder body and a cylinder cover, and the fastening device is positioned on the circumferential surface of the shell or the lower end surface of the shell; the filter liner 5 also comprises a vertical shaft structure 51 provided with a side wall hole structure 55, a transverse moving member 53 with limit, an elastic member and a frame structure 52 for moving and guiding the transverse moving member 53 and supporting the elastic member in a deformation way; the side wall hole structure 55 of the vertical shaft structure 51 is vertically spliced and matched with the spliced handles 1 to be spliced, and the side wall hole structure 55 positioned at the outer side of the spliced handles 1 corresponds to the transverse notch 17 of the spliced handles 1; the frame structure 52 is either a structure for moving a single traverse member 53 to guide and support a single elastic member or a structure for moving two traverse members to guide and support two elastic members simultaneously; the rear limiting structure of the transverse moving part which is arranged in the frame structure and is in contact fit with the elastic part is in contact fit with the outer side of the side wall hole structure, and the front part of the transverse moving part extends out of the inserting position at the port of the inner side of the side wall hole structure; under the action of horizontal force in the vertical shaft structure, the transverse moving part 53 horizontally moves along the horizontal hole structure and the frame structure 52 to the position to be inserted at the inner side port of the side wall hole structure, and after the horizontal component force from the vertical shaft structure is removed, the transverse moving part 53 moves back to the inserting position under the action of elastic force of the elastic part.

In this case, the horizontal forces in the shaft structure 51 come from the handle means to be inserted into the shaft structure. The inserted link of the handle device moves downwards from the upper limit corresponding to the upper step structure 11 under the action of vertical force, and generates horizontal component force on the deformation movable piece, so that the deformation movable piece generates deformation displacement in the horizontal direction, and the transverse movable piece is pushed to overcome the acting force of the elastic piece and shrink to the position to be inserted. When the vertical force applied to the inserted link is cancelled, the deformation movable part is restored to the previous position to be inserted by self resilience force; at this time, the lateral moving member moves to the insertion position under the action of the elastic member, that is, the insertion position (the lateral opening of the insertion handle device) where the front portion of the lateral moving member extends out of the inner side port of the sidewall hole structure 55.

First structural mode of the frame structure: the frame structure 52 is a structure for moving one lateral moving member 53 to guide and support a single elastic member 54. For the two side wall hole structures which are symmetrically arranged, two sets of the lateral moving member 53 and the elastic member 54 are arranged, and thus two frame structures 52 are correspondingly arranged (see fig. 1).

The second structural mode of the frame structure: the frame structure is a structure for guiding the movement of the two transverse moving members and supporting one elastic member at the same time. For two side wall hole structures which are symmetrically arranged, two transverse moving parts and an elastic part are arranged, for example, the two transverse moving parts are arranged in an annular elastic part (closed loop or open loop), and a frame structure is correspondingly arranged for guiding and supporting the two transverse moving parts. The annular elastic piece is deformed into the outward movement of the transverse moving piece through stress to give a position space, and the position corresponds to the position to be inserted of the transverse moving piece.

Example 9. On the basis of the embodiments 7 and 8, an inward convex tooth structure is arranged on the inner side wall of the vertical shaft structure, an outward convex tooth structure of the columnar rotary clamping device to be spliced is vertically inserted and rotationally inserted (clamped) into a matched opening, and a rotary matching space for the insertion and rotary clamping matching (the upper contact matching and the lower contact matching of the inward convex tooth structure and the outward convex tooth structure) of the outward convex tooth structure is arranged below the inward convex tooth structure, so that a filter liner of the inward convex tooth structure is integrally connected with an upper machine seat or a handle of the columnar rotary clamping device in the vertical direction. The insertion position of the transverse moving member does not affect the insertion and the rotary insertion (clamping) of the outward convex tooth structure.

The side wall hole structure can be located above the inward cam structure, wherein the side wall hole structure is preferably arranged right above the inward cam structure, so that the transverse moving part at the plugging position avoids the outward cam structure of the columnar rotary clamping device to be plugged, and then the vertical shaft structure has a smaller inner contour structure.

The side wall hole structure can also be positioned in the range of the same height layer (comprising the spin-fit space) of the inward convex tooth structure. At this time, the front part of the lateral moving part which corresponds to the gap between the two inward convex tooth structures and is positioned in the side wall hole structure and extends out of the port at the inner side of the side wall hole structure is arranged outside the rotating channel of the outward convex tooth structure of the columnar rotary clamping device to be spliced.

The side wall hole structure can also be positioned below the inward convex tooth structure. The lower part of the shaft structure provided with the side wall hole structure is limited by not influencing the upper inward convex tooth structure, so that the insertion and the screwing of the outward convex tooth structure are not influenced, the handle device is convenient to insert into the lower part of the shaft structure, and the inner contour structure of the regular polygon is preferable.

Example 11. On the basis of the embodiments 8, 9 and 10, the inner side wall of the vertical shaft structure is provided with an inner contour structure matched with a non-circular section structure which is in plug-in fit and rotary linkage with a handle insertion pipe to be inserted.
