It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

As shown in fig. 1-9, a water purifier comprises a body 100a and a filter element assembly 200a, wherein the filter element assembly 200a is detachably fixed on the body 100 a. The outer wall of the filter element assembly 200a is provided with a mounting post 201a, the mounting post 201a in this embodiment is located on the outer side wall, and of course, the mounting post may also be arranged on the outer end wall of the filter element assembly. Here, since the force direction of the mounting post 201a is parallel to the dismounting direction when dismounting the filter element assembly 200a, or at least has a component force along the dismounting direction, the extending direction of the mounting post 201a is required to be perpendicular to the dismounting direction of the filter element assembly 200a, and here, the extending direction of the mounting post should be understood as having at least an extending component perpendicular to the dismounting direction of the filter element assembly, for example, the extending direction of the mounting post having an included angle smaller than 90 ° and larger than 0 ° with respect to the dismounting direction of the filter element assembly can be regarded as having an extending component perpendicular to the dismounting direction of the filter element assembly, or stated differently, the extending direction of the mounting post is not parallel to the dismounting direction of the filter element assembly. It should be noted that, in the embodiment where the mounting post is located on the outer side wall, the mounting post is not necessarily parallel to the dismounting direction of the filter element assembly as a protruding structure protruding from the outer side wall, and in the embodiment where the mounting post is located on the outer end wall, the arrangement mode where the mounting post is parallel to the dismounting direction of the filter element assembly needs to be eliminated, generally, an axially extending support structure can be arranged on the outer end wall of the filter element assembly, and the mounting post is arranged on the support structure.

The side of the filter element assembly 200a is provided with an operating element 101a, correspondingly, the body 100a is provided with a rotating shaft 102a, the operating element 101a is provided with a through hole 103a, the operating element is fixed with the rotating shaft 102a through the through hole 103a and can rotate around the rotating shaft 102a, in the embodiment, the body 100a is provided with a side wall 300a deviating from the direction of the filter element assembly 200a, the rotating shaft 102a is arranged on the operating element 101a, and the operating element 101a can be attached to the side wall 300a when rotating around the rotating shaft 102a, so that the operating element 101a is prevented from being stressed and deflected, of course, a sliding part and a sliding groove which are mutually matched can be arranged between the side. As another embodiment of the setting position of the operation member, a boss may be provided on a side portion of the filter element assembly, and a side wall facing the direction of the filter element assembly may be formed on a side surface of the boss, and the rotation shaft and the operation member may be fixed to the side wall.

In this embodiment, the operating element 101a is provided with the sliding groove portion 104a and the handle portion 105a, the user can manually operate the handle portion 104a to drive the operating element 101a to rotate, the structure is simple and reliable, the operation difficulty is low, and the handle portion 105a is far away from the through hole 103a, so that the operating element 101a can be driven to rotate by applying a small force to the handle portion 105a according to the lever principle. Of course, the operating member may be driven to rotate by a power mechanism such as a motor, a pneumatic motor, a hydraulic motor, or the like, and the same effect as that of manual driving may be achieved by applying the power of the power mechanism to the handle portion, for example. In addition, in the scheme, when the filter element assembly is replaced, each operating part can only control the disassembly of one filter element assembly, and the two operating parts are not connected with each other. Therefore, under the condition that a plurality of filter element assemblies need to be disassembled at one time, the disassembly of each filter element assembly is independent, the time for completing the disassembly is longer, and the efficiency is lower. As another embodiment of the operating member, in fig. 10, a link 109b may be provided between the plurality of operating members 101b, and the operating members 101b and the link 109b may be connected to each other by a pin so as to be rotatable relative to each other. When trading filter element group spare 200b, only need rotate connecting rod 109b, can drive a plurality of operating parts 101b synchronous rotation, can once only accomplish the dismantlement of a plurality of filter element group spares 200b to reduce and trade the core time, improve and trade core efficiency.

The slide groove portion 104a is provided with a slide groove 106a, the slide groove 106a has an opening end 107a and a sealing end 108a, the distance from the opening end 107a to the rotating shaft 102a is larger than the distance from the sealing end 108a to the rotating shaft 102a, and the operating element 101a rotates around the rotating shaft 102a to make the mounting column 201a slide back and forth between the opening end 107a and the sealing end 108a of the slide groove 106 a. The operating member 101a has a first position and a second position during the rotation, and in the first position, the mounting post 201a is located at the sealing end 108a to press the filter element assembly 200a on the body 100a, and in the second position, the mounting post 201a is located at the opening end 107a to disassemble and assemble the filter element assembly 200a and the body 100 a. In this embodiment, the filter element assembly 200a is assembled and disassembled in a direction parallel to the axial direction thereof, so that the moving direction of the mounting post 201a is also parallel to the axial direction of the filter element assembly 200a, and the rotating shaft 102a is disposed on the side of the straight line of the moving path of the mounting post 201 a. The specific positions and the movement tracks are shown in fig. 5, B1 and B2 are the positions of the mounting post 201a when the operating element 101a is located at the first station and the second station, respectively, during the rotation of the operating element 101a, the mounting post performs reciprocating translation between B1 and B2, a is the position of the rotating shaft 102a, a perpendicular line passing through a and serving as an extension line of a connecting line between B2 and B1, and a point of intersection is C, because of structural limitation, the lengths of the line segments a-C are unchanged, and the length of the line segment B2-C is greater than that of the line segment B1-C, so that the length of the line segment a-B2 is greater than that of the line segment a-B1, wherein the line segment a-B2 is a line segment formed from the opening end 107a to the rotating shaft 102a, and the line segment a-B1 is a line segment formed. Of course, the rotation axis can also be disposed on the extension line of the moving path of the mounting post, which is equivalent to the combination of point a and point C in fig. 5, and the length of the line segment a-B2 is also greater than the length of the line segment a-B1. In addition, in order to improve the convenience and comfort of operation, the outer surface of the mounting post 201a and the inner surface of the sliding groove 106a can be made relatively smooth, the friction force between the two cannot be too large, and preferably, a pulley can be arranged on the mounting post to replace sliding friction with rolling friction.

It should be added that the filter element assembly can be disassembled and assembled in other embodiments not parallel to the axial direction, for example, as shown in fig. 11 and 12, the disassembly and assembly direction of the filter element assembly 200c is perpendicular to the axial direction, specifically, the sidewall of the filter element assembly 200c is provided with an insertion part 301c forming the water inlet port interface, the body 100c is provided with an insertion matching part 302c inserted into the interface at a corresponding position, and the rotary operating part 101c can disassemble the filter element assembly 200c along the direction perpendicular to the axial direction of the filter element assembly 200c through the mounting column 201 c.

The slide groove 106a has a first guide surface 111a on the side close to the rotation shaft 102a and a second guide surface 112a on the side far from the rotation shaft 102 a. During the operation member 101a going from the first station to the second station, the pressing of the first guide surface 111a against the mounting post 201a generates at least a component force to the mounting post 201a outwardly parallel to the filter cartridge assembly 200a, so that the filter cartridge assembly 200a is removed outwardly. In other embodiments, for example where the cartridge assembly has a tendency to move in an outward direction of removal in the assembled state, for example where the cartridge assembly is arranged vertically and needs to be removed downwardly, the cartridge assembly has a tendency to disengage downwardly under the influence of its own weight and the water inside it, or a tendency to disengage under the influence of water pressure at the interface between the cartridge assembly and the body, then the mounting post is pressed against the second guide surface during the passage of the operating member from the first position to the second position, thereby preventing the cartridge assembly from being removed from the body quickly. During the passage of the operating member 101a from the second station to the first station, the pressing of the second guide surface 112a against the mounting post 201a generates at least a component force inwardly of the mounting post 201a parallel to the filter element assembly 200a to load the filter element assembly 200a inwardly. In other embodiments, for example, when the mounting post is located at the open end of the chute, the filter element assembly has a tendency to move in the inward loading direction, for example, the filter element assembly is vertically arranged and needs to be loaded downwards, and the filter element assembly has a tendency to be loaded downwards under the action of its own weight, so that during the operation member is transferred from the second station to the first station, the mounting post is pressed against the first guide surface, and the filter element assembly is prevented from being loaded into the body quickly under its own weight, which may cause impact force and damage to the machine or the joint seal. Preferably, the distance from any point on the first guide surface 111a and the second guide surface 112a to the rotating shaft 102a gradually increases from the opening end 108a to the opening end 107a, so that the movement of the filter element assembly 200a is continuous no matter in the process of disassembling or assembling the filter element assembly, and the blocking phenomenon during disassembling and assembling is avoided. The first guide surface 111a and the second guide surface 112a in this embodiment are transited by a pressing surface 114a, the pressing surface 114a presses the mounting post 201a, and the pressing surface 114a is an inner wall of the sealing end 108a, so as to reliably fix the filter element assembly 200 a.

Generally, the first guide surface and the second guide surface are smooth curved surfaces or flat surfaces, and as can be seen from the above analysis, the filter element assembly can be disassembled as long as the distance from the opening end to the rotating shaft is larger than the distance from the sealing end to the rotating shaft. However, in order to save more labor and improve the operation efficiency when the filter element assembly is disassembled and assembled, as shown in fig. 6 and 7, for applying the acting force F0 on the handle part and generating the acting force F1 on the mounting column, the smaller the component force of the acting force F1 in the vertical direction in the figure is better, the larger the component force in the horizontal direction is better, and optimally, the F1 always keeps in the horizontal direction during the rotation movement of the handle. In the embodiment, an involute structure is adopted, firstly, the distance from a starting point to a terminal point on a linear form to a rotation center is known to be longer and longer in the forming process of the involute, and secondly, the normal of any point on the involute is tangent to a base circle. The first guide surface and the second guide surface are preferably formed in an involute type structure in which the base circle of the involute is centered on the rotation axis a and the radius is the line segment a-C in fig. 5, so that the force F1 acting on the mounting post can be always kept in the same direction as the filter element assembly and disassembly direction.

The first guide surface 111a is arranged at an equal distance from the second guide surface 112a, preferably at a distance slightly larger than the outer diameter of the mounting post 201a, on the one hand, to provide a small resistance to sliding of the mounting post 201a in the slide groove 106a, and on the other hand, to prevent the mounting post 201a from moving in the direction of removal of the filter cartridge assembly due to an excessive clearance from both sides of the first and second guide surfaces when moving to the intermediate position of the slide groove 106 a. The slide groove 106a further has a third guide surface 113a on the side of the second guide surface 112a close to the open end 107a, and the distance between the third guide surface 113a and the first guide surface 111a gradually increases toward the open end 107a, which facilitates guiding the mounting post 201a into the slide groove 106a during the assembly of the filter cartridge assembly 200 a.

The first guide surface 111a has a pre-mounting surface 115a, and when the operating member 105a is located at the second station, the projection of the portion of the operating member 105a located on the side of the pre-mounting surface 115a opposite to the rotating shaft 102a along the mounting and dismounting direction of the filter element assembly 200a does not cover the pre-mounting surface 115a, i.e. the projection of the handle part 105a along the mounting and dismounting direction of the filter element assembly 200a in the embodiment does not cover the pre-mounting surface 115 a. During the assembly of the cartridge assembly 200a, the mounting post 105a may be placed on the pre-mounting surface 115a and then the operating member 105a is rotated so that the third guide surface 113a presses the mounting post 105a and presses the mounting post 105a into the chute 106a, or the mounting post may be moved along the first guide surface toward the closed end, provided that the cartridge assembly has a tendency to be assembled inwardly. Meanwhile, when the pre-installation surface 115a is also used for disassembling the filter element assembly 200a, the installation column 105a is placed at a position which is convenient for a user to further draw out the filter element assembly 200a without interfering with the operation part 105 a.

Be equipped with on body 100a and be in spacing first spacing portion and the spacing portion of second of first station and second station time phase with operating part 101a respectively, operating part 101a locking position of being convenient for avoids not assembling in place and appearing leaking when packing into the filter element subassembly, and operating part turned angle is not enough and can't take out when perhaps dismantling the filter element subassembly, and operating part turned angle is too big when also perhaps dismantling the filter element subassembly and makes operating part and erection column form new interference etc..

In this embodiment, the first limiting portion is a clamping portion 121a, the free end of the handle portion 105a is provided with a clamping matching portion 123a, when the operating element 101a is located at the first station, the clamping portion 121a is in clamping matching with the clamping matching portion 123a, and since the clamping matching portion 123a is disposed at a position far away from the rotating shaft 102a, on one hand, a relatively small clamping force can form a relatively large clamping moment to reliably press and hold the filter element assembly 200a, and on the other hand, a user can apply a relatively small force at the free end of the handle portion 105a to overcome the clamping force and rotate the operating element 101a out. The second limiting part is a limiting protrusion 122a located on the side of the rotating shaft 102a, the sliding groove part 104a is provided with a limiting abutting part 124a, when the operating part 101a is located at the second station, the limiting abutting part 124a abuts against the limiting protrusion 122a, and the operating part 101a is prevented from rotating over the second station.

As another embodiment of the first limiting portion, as shown in fig. 13, the clamping portion 303d in this structure can rotate around a convex column on the body 100d, the handle portion 105d is provided with a clamping engaging portion 304d, the clamping engaging portion 304d is in an arc segment shape, and the clamping portion 303d has a groove therein to engage with the arc segment, so as to limit the displacement of the operating element. When the filter element assembly is disassembled, the clamping part 303d is unscrewed clockwise, and then the operating part is rotated; when packing into filter element group spare, the operating parts back that targets in place, anticlockwise screw in joint portion 303d is with fixed operating parts, and this kind of mode is fixed more reliably, and filter element group spare is changed equally simple and conveniently.

The filter element assembly 200a is provided with a plug part 301a, the body 100a is provided with a plug matching part 302a, generally, the body 100a is provided with a mounting seat fixedly matched with the filter element assembly 200a or an integrated water circuit board, the plug part 301a is internally provided with a water circuit to form an interface of a water inlet and a water outlet of the filter element assembly 200a, and the plug matching part 302a and the plug part 301a are oppositely arranged. The inserting part 301a in this embodiment is a column structure, the inserting matching part 302a is a groove structure, the inserting part 301a can be inserted into the inserting matching part 302a, of course, the groove structure can be arranged on the filter element assembly, and the column structure is arranged on the body. When the operating part 101a is at the first station, the insertion part 301a and the insertion matching part 302a are in insertion matching so that the filter element assembly 200a is communicated with a water channel on the body 100a, a plurality of sealing rings are arranged on the insertion part 301a, and the sealing rings are in sealing matching with the inner wall of the insertion matching part 302 after insertion matching. When the operating member 101a is at the second station, the insertion part 301a is disengaged from the insertion mating part 302 a. Because the frictional resistance between above-mentioned grafting portion 301a and the grafting cooperation portion 302a is great, makes when dismantling filter element group spare 200a, and the resistance of initial segment stroke is great, and the user is difficult to extract to even overcome the resistance of initial segment stroke and extract the filter element group spare after, because inertia problem makes the filter element group spare taken out too much easily once, influence user experience.

Wherein, the inserting direction of the inserting part 301a and the inserting matching part 302a is consistent with the assembling and disassembling direction of the filter element component 200 a. In order to meet the requirement of relative positions of the plugging part 301a and the plugging matching part 302a corresponding to the first station and the second station, the difference between the distance from the open end 107a to the rotating shaft 102a and the distance from the closed end 108a to the rotating shaft 102a is not less than the plugging stroke of the plugging part 301a and the plugging matching part 302a, that is, in fig. 5, the length of the line segment B1-B2 is not less than the plugging stroke of the plugging part 301a and the plugging matching part 302 a.
