The core element of the filtering equipment is a filter and is used for filtering impurities or harmful substances and the like in input liquid, so that the output liquid meets certain cleanliness requirements. Through setting up a casing in the outside of filter, install the filter in order to form a filter flask structure inside the casing, the filter flask is provided with water inlet and delivery port, water inlet and delivery port and outside water path connection, and liquid gets into from the water inlet, flows out from the delivery port after the filtering action through the filter. When the filter reaches life-span or damages, can dismantle the filter flask, after the filter of renewal, again with filter flask and outside water route connection. Taking a household water purifier as an example, the external water path is generally integrated to form a water path plate, and the filter bottle is detachably connected with the water path plate through a mounting structure.

Therefore, the waterway plate 200 includes a waterway plate inlet 202 and a waterway plate outlet 203, and the waterway plate 200 is provided with a connection port 201 for connecting with the filter bottle 100. As can be seen from fig. 2 and 3, three filter bottles 100 are simultaneously installed on one water channel plate 200, the size of each filter bottle 100 and the composition of the filter element can be the same or different, and different functions can be realized correspondingly, each filter bottle 100 is provided with a connecting pipe 23 corresponding to the connecting port 201, in the first embodiment, the connecting pipe 23 is arranged on the second connecting part 2, and through the installation of the second connecting part 2 and the first connecting part 1, the connecting pipe 23 can be inserted into the corresponding connecting port 201 and sealed, so as to realize the introduction or the derivation of water flow into or out of the filter bottle 100.

It is contemplated that a plurality of filter bottles 100 mounted on a waterway plate 200 may be connected in parallel or in series, and may be implemented by connecting pipes in the waterway plate 200, for example, in fig. 2 and 3, it may be configured as follows: external water flows in from a water inlet 202 of the waterway plate, enters the first filter bottle 100 for filtering with a first function, returns to the waterway plate 200, enters the second filter bottle 100 for filtering with a second function, returns to the waterway plate 200, enters the third filter bottle 100 for filtering with a third function, and finally flows out from a water outlet 203 of the waterway plate; that is, three filter bottles 100 have three filtering functions, and the fixing structure between each filter bottle 100 and the waterway plate 200 is the same.

In fig. 2 and 3, since the entire waterway plate 200 is rectangular, and the first connecting member 1 is disposed on the bottom surface of the waterway plate 200, the direction a in the first embodiment may represent a direction perpendicular to the bottom surface of the waterway plate 200, and the direction B may represent a direction perpendicular to the side surface of the waterway plate 200; in other embodiments, any structure in which the filter bottle 100 is connected to the water channel plate 200 along the direction a, the third connecting member 3 is connected to the water channel plate 200 along the direction B, and the direction a is perpendicular to the direction B is within the scope of the present invention.

The specific combination and the snap-fit connection of the first connector 1, the second connector 2 and the third connector 3 will be described in detail below.

The first connecting member 1 may be a base, i.e., a first base 13, disposed on the water passage board 200, and the first base 13 is provided with a first groove 11 and a second groove 12. The first base 13 is convexly arranged on the water channel plate 200, specifically, the lower surface of the water channel plate 200 in the first embodiment; the first groove 11 is arranged on one surface of the first base 13, which faces away from the water channel plate 200, and the outline shape of the first groove 11 is the same as that of the second connecting piece 2; the second groove 12 is provided on a sidewall of the first base 13. Further, the first groove 11 is arranged along the direction A, the second groove 12 is arranged along the direction B, and the first groove 11 is communicated with the second groove 12.

Correspondingly, the second connector 2 may be a base provided on the filter flask 100, i.e. the second base 21, the second base 21 being insertable into the first recess 11; the second base 21 is provided with a third groove 22, when the second base 21 is inserted into the first groove 11, the second groove 12 is aligned with the third groove 22, and the third connecting member 3 passes through the second groove 12 and the third groove 22 to connect the first connecting member 1 and the second connecting member 2.

Correspondingly, in the first embodiment, the third connecting member 3 is a connector clip for realizing the snap-fit connection, that is, the third connecting member 3 deforms and abuts against the inner surfaces of the first connecting member 1 and the first connecting member 2, and the generated friction force can ensure the connection strength and realize the snap-fit fixation. It is worth mentioning that in the first embodiment, the third connecting member 3 may be formed integrally, and is further preferably made of an elastic material.

The first embodiment provides a structure of a third connecting part 3, where the third connecting part 3 includes a plurality of jaws, the corresponding second grooves 12 include a plurality of second sub-grooves corresponding to the plurality of jaws, the third grooves 22 include a plurality of third sub-grooves corresponding to the plurality of jaws, and each jaw is connected with the corresponding second sub-groove and third sub-groove in a clamping manner, and this structure can better ensure the connection strength of the clamping.

In the first embodiment, as shown in fig. 2, the third connecting member 3 includes a connecting portion 33 and three claws arranged on the connecting portion 33, wherein two ends of the connecting portion 33 are connected to one first claw 31, and one second claw 32 is arranged between the two first claws 31. Correspondingly, the second groove 12 comprises three second sub-grooves arranged corresponding to the first jaw 31 and the second jaw 32, the third groove 22 comprises three third sub-grooves arranged corresponding to the first jaw 31 and the second jaw 32, and the first jaw 31 and the second jaw 32 can simultaneously abut against the first base 13 and the second base 21.

In other embodiments, the structure of the third connecting element 3 and the cooperation of the third connecting element 3 with the second recess 12 and the third recess 22 may be provided by a practical structure, for example, the third connecting element 3 comprises a pawl, one for each of the second recess 12 and the third recess 22.

To better illustrate that the first jaw 31 and the second jaw 32 can abut against the first base 13 and the second base 21 simultaneously, fig. 4 is a partial cross-sectional view of a filter bottle mounting structure provided in an embodiment of the present invention after mounting, and fig. 5 is a partial enlarged view at C in fig. 4. As can be seen from fig. 3, 4 and 5, during actual installation, the filter flask 100 moves along direction a, so that the second base 21 is inserted into the first groove 11, and the connecting pipe 23 is correspondingly inserted into the connecting port 201 to realize sealed connection; at this time, three second sub-grooves in the second grooves 12 are aligned with three third sub-grooves in the third grooves 22, and two first claws 31 and one second claw 32 simultaneously penetrate through the aligned second sub-grooves and the aligned third sub-grooves, so that the snap connection is realized.

As can be seen from fig. 4 and 5, the first base 13 is a hollow structure, and for better description, the first base 13 can be described as a hollow structure surrounded by a front wall, a rear wall, a left wall and a right wall, that is, the first groove 11 is surrounded by four side walls. The cross-sectional shape of the second base 21 is the same as the cross-sectional shape of the first groove 11, in the first embodiment, the cross-sectional shape of the second base 21 is approximately waist-shaped, and the first groove 11 is correspondingly configured to be approximately waist-shaped hole structure.

Referring to fig. 4, after the second base 21 is inserted into the first recess 11, the second base 21 is received inside the first base 13. The two second grooves 12 corresponding to the first claws 31 are through grooves penetrating through the front wall and the rear wall of the first base 13, and the two first claws 31 are correspondingly arranged into a longer structure; when mounted, the two first claws 31 pass through the two second grooves 12, i.e. the free ends of the first claws 31 pass through the front and rear walls of the first base 13 in fig. 4. The inner wall of the first jaw 31 can abut against the inner wall of the second groove 12 and the outer wall of the second base 21, and clamping in one direction is achieved.

The second grooves 12 corresponding to the second jaws 32 are through slots which only penetrate the front wall of the first base 13, so that the second jaws 32 are correspondingly arranged in a shorter configuration; when mounted, the second catch 32 passes through the corresponding second recess 12, i.e. the free end of the second catch 32 passes through the front wall of the first base 13 in fig. 4. The outer wall of the second jaw 32 can now abut against the inner wall of the second recess 12 and the outer wall of the second base 21, achieving clamping in the other direction.

In the first embodiment, two first claws 31 can simultaneously clamp the first base 13 and the second base 21 from the outside to the inside from two sides of the second base 21, and the second claws 32 clamp the first base 13 and the second base 21 from the inside to the outside, so that the first claws 31 and the second claws 32 can be matched to clamp the first base 13 and the second base 21 from two directions. The arrangement mode is simple in structure and convenient to install, and rapid insertion can be achieved.

Further, the engagement between the third link 3 and the second groove 12 and the third groove 22 is achieved by the friction force generated by the deformation of the third link 3 abutting against the inner walls of the second groove 12 and the third groove 22. Under the action of external forces, the third connecting element 3 may have the problem of slipping out of the second groove 12 and the third groove 22 in the direction B against this frictional force. For this, it is preferable that the second jaw 32 is provided in a structure including two second sub-jaws 321 disposed at intervals, and a hook member 322 is provided on each second sub-jaw 321. As shown in fig. 4 and 5, the two second sub-jaws 321 are identical in structure and symmetrically arranged, and each second sub-jaw 321 corresponds to one first jaw 31 on the same side, so as to better abut on the first base 13 and the second base 21. The barb element 322 is arranged on the side wall of the second sub-jaw 321, and in the first embodiment, the cross section of the barb element 322 is in a trapezoid shape, and gradually shrinks towards the middle position from the end part of the second sub-jaw 321 to form two inclined surfaces.

For better description, the slope of the barb 32 on the side near the free end of the second sub-pawl 321 in fig. 5 is referred to as a first slope, and the corresponding slope on the side near the connecting portion 33 is referred to as a second slope. The first inclined surface of the barb element 32 can play a guiding role when the third connecting element 3 is inserted; after the first inclined surface is inserted, the body of the second sub-jaw 321 is protruded from the second sub-jaw 321, so that the body of the second sub-jaw 321 can be abutted against the second base 21; the second slope can abut on the first base 13. When the third connecting member 3 is pulled out, the second sub-claw 321 needs to be elastically deformed and bent inward under the guiding action of the second inclined surface, so that the third connecting member 3 can be pulled out. Through setting up barb piece 322, need exert certain power when extracting and just can make the sub-jack catch 321 of second take place elastic deformation and pulled out, consequently can solve under the exogenic action, the problem of roll-off in second recess 12 and the third recess 22 is probably followed to third connecting piece 3 in direction B, structural design is reasonable, convenient to use.

When the third connecting element 3 is inserted into the corresponding second groove 12 and the corresponding third groove 22 along the direction B, the end of the stroke can be determined by the lengths of the first jaw 31 and the second jaw 32, and the connecting part 33 is abutted against the first base 13; that is, the insertion process is terminated with the connecting portion 33 abutting against the first base 13, and the insertion cannot be continued. In order to prevent the connection part 33 from directly abutting on the first base 13 due to the rapid insertion, resulting in a problem of damage to the connection part 33 or the first base 13, it is also preferable to provide a protrusion structure 323. As shown in fig. 5, a convex structure 323 is formed at the joint of the second sub-jaw 321 and the connecting portion 33, the cross section of the convex structure 323 is circular arc, and the circular arc-shaped convex structure 323 can make the abutment with the first base 13 form a certain buffer, so as to solve the problem of possible damage.

The actual installation process of the filter flask installation structure provided by the embodiment of the invention is as follows:

step one, the filter bottle 100 is held by hand, and gradually moves towards the water channel plate 200 along the direction A, so that the second base 21 on the filter bottle 100 is inserted into the first groove 11, and at the moment, the plurality of connecting pipes 23 are inserted into the corresponding connecting ports 201 to realize sealing. When plugged into place, the second groove 12 is aligned with the third groove 22.

In the second step, the third connecting piece 3 gradually moves towards the water route board 200 along the direction B, the first claws 31 are firstly inserted into the corresponding second grooves 12 and the corresponding third grooves 22, then the second claws 32 are gradually inserted into the corresponding second grooves 12 and the corresponding third grooves 22, and the first inclined surfaces of the barb pieces 322 play a guiding role.

Step three, when the protruding structures 323 abut against the first base 13, the barb elements 322 just penetrate through the corresponding second grooves 12, the barb elements 322 abut against the second base 21 inside, the second inclined surfaces of the barb elements 322 abut against the corresponding first base 13, and the whole third connecting element 3 is completely limited in the direction B, so that the fixing process of the water channel plate 200 and the filter bottle 100 is realized.

During actual disassembly, the third connecting piece 3 is pulled to be far away from the water channel plate 200 along the direction B, under the guidance of the second inclined plane, the two second sub-claws 321 are deformed to be close to each other, and the barb elements 322 are abutted against the inner wall of the second groove 12 until the third connecting piece 3 is separated from the first connecting piece 1 on the water channel plate 200, so that disassembly is realized.

As can be seen from the above description, in the first embodiment, when the liquid in the water channel plate 200 generates large pressure fluctuation during operation, the generated impact force impacts the filter bottle 100 along the direction a, and the impact force acts on the third connector 3 along the direction a, which can be expressed as the thickness direction of the third connector 3, so that the impact force is transmitted to the third connector 3, and as long as the structural strength of the third connector 3 is good, the impact force along the direction a can be borne.

Compared with the scheme that the impact force acts on the joint to cause the screw thread to lose efficacy in the prior art, the interaction force of the joint of the water path plate 200 and the filter bottle 100 is along the B direction, the A direction and the B direction are mutually perpendicular, and the impact force cannot act on the joint, so that the joint cannot lose efficacy.

Therefore, the direction A and the direction B are perpendicular to each other, so that the mutual acting force at the joint of the water channel plate and the filter flask is perpendicular to the direction of the impact force generated by the liquid in the water channel plate, the structural strength of the joint is better, and the reliability is higher.

Example two:

the main structure of the second embodiment is the same as that of the first embodiment, except that the first connecting piece 1, the second connecting piece 2 and the third connecting piece 3 are connected by screw threads.

Specifically, the third connecting member 3 may be a bolt, and is a threaded hole corresponding to the second groove 12 and the third groove 22; the screw hole is provided with a plurality ofly, and the bolt correspondence is provided with a plurality ofly.

During actual installation, the steps are the same as those in the first embodiment; in the second step, the bolts pass through the corresponding second groove 12 and third groove 22 and are in threaded connection with the second groove 12 and third groove 22, so that the fixing process of the water channel plate 200 and the filter bottle 100 can be directly realized.
