[0072] <Filtering device>

[0073] As Figures 1 to 8 shown, this embodiment provides a filtering device, comprising:

[0074] An installation frame 1, which is used for installing a filter net 6;

[0075] The guiding member 2 is arranged on the installation frame 1, and the guiding member 2 and the installation frame 1 enclose an installation cavity 11; specifically, the structure of the installation cavity 11 is adapted to the structure of the filter net 6; in this embodiment, the installation cavity 11 is in a cuboid structure; one end of the installation cavity 11 forms an opening, and the opening communicates with the installation cavity 11; the filter net 6 can slide into or out of the installation cavity 11 through the opening, thereby realizing the installation or disassembly of the filter net 6; the guiding member 2 is formed with an installation hole 23, and the guiding member 2 is connected to the installation frame 1 through the installation hole 23 and a fastener; the guiding member 2 is formed with a first sliding groove 21; a second sliding groove 22 is formed on one side wall of the first sliding groove 21, and both the second sliding groove 22 and the first sliding groove 21 extend along the first direction; the second sliding groove 22 and the first sliding groove 21 are arranged side by side and communicate with each other along the second direction; the first direction is the length direction of the installation cavity 11, and the second direction is the thickness direction of the installation cavity 11;

[0076] The sliding assembly includes a first slider 3 and a second slider 4. The first slider 3 is slidably arranged in the first sliding groove 21 along the first direction, the second slider 4 is slidably arranged in the second sliding groove 22 along the first direction, and the second slider 4 can slide relative to the first slider 3 along the second direction; a first abutting portion 411 and a second abutting portion 412 are formed on the side of the second slider 4 away from the first slider 3;

[0077] The filter net 6, the filter net 6 and the second slider 4 have a first working state, a second working state and a third working state;

[0078] When the filter net 6 and the second slider 4 are in the first working state, the filter net 6 abuts against the first abutting portion 411, so that the filter net 6 slides into the installation cavity 11 along the first direction. The first slider 3 and the second slider 4 can act together along the first direction and slide synchronously along the first direction. Furthermore, the filter net 6 can slide into the installation cavity 11; the first slider 3 cooperates with the first sliding groove 21, and the second slider 4 cooperates with the second sliding groove 22 to play a guiding role, ensuring accurate positioning of the filter net 6 and enabling the filter cavity to slide into the installation cavity 11 smoothly;

[0079] When the filter net 6 and the second slider 4 are in the second working state, the filter net 6 abuts against the second abutting portion 412. The first slider 3 and the second slider 4 act together along the second direction and make the first slider 3 clamped in the first sliding groove 21. Furthermore, the filter net 6 is fixed in the installation cavity 11; one side of the filter net 6 abuts against the second abutting portion 412, so that the second slider 4 acts on the first slider 3. Then the first slider 3 abuts against the side wall of the first sliding groove 21. Then the first slider 3 is fixed relative to the first sliding groove 21, and the second slider 4 is fixed relative to the second sliding groove 22, making the filter net 6 firmly and reliably fixed in the installation cavity 11;

[0080] When the filter net 6 and the second slider 4 are in the third working state, the filter net 6 is not in contact with the first abutting portion 411 or the second abutting portion 412, so that the filter net 6 slides out of the installation cavity 11 in a direction opposite to the first direction, and thus the filter net 6 can be detached from the installation cavity 11.

[0081] In this way, the installation structure of the filter net is optimized, the process of disassembling and installing the filter net 6 is simplified, the filter net 6 can smoothly slide into or out of the installation cavity 11, the filter net 6 can be accurately positioned, the time required for disassembling and installing the filter net 6 is shortened, the user experience is improved, and the problems of cumbersome process, long required time, inconvenient disassembly and installation, and inaccurate positioning of the filter net 6 are solved.

[0082] Aiming at the problem that the filter net 6 is not firmly fixed in the installation cavity 11, this embodiment proposes that the filter net 6 and the second slider 4 further have a fourth working state, and the fourth working state is located between the first working state and the second working state.

[0083] When the filter net 6 and the second slider 4 are in the fourth working state, the filter net 6 can move from the first abutting portion 411 to the second abutting portion 412, and the second slider 4 can slide relative to the first slider 3 in the second direction, so that the first slider 3 and the second slider 4 act together in the second direction, and then the first slider 3 can be clamped in the first sliding groove 21.

[0084] Furthermore, the second slider 4 includes a sliding column 42 and an abutting seat 41. The sliding column 42 is slidably arranged in the second sliding groove 22, and the abutting seat 41 is arranged at one end of the sliding column 42 away from the first slider 3. The abutting seat 41 is formed with a first abutting portion 411 and a second abutting portion 412. The first abutting portion 411 and the second abutting portion 412 are arranged in sequence along the first direction, and one end of the first abutting portion 411 is connected to one end of the second abutting portion 412. In this way, one side of the filter net 6 can move from the first abutting portion 411 to the second abutting portion 412 along the first direction, and then the filter net 6 and the second slider 4 enter the second working state from the first working state.

[0085] Aiming at the problem that the filter net 6 is not firmly fixed in the installation cavity 11, this embodiment also proposes that the abutting seat 41 is further formed with a limiting portion 413, and the limiting portion 413 is connected to the other end of the second abutting portion 412.

[0086] When the filter net 6 and the second slider 4 are in the second working state, one side of the filter net 6 abuts against the second abutting portion 412, and the other side of the filter net 6 abuts against the limiting portion 413, so that the filter net 6 is fixed in the installation cavity 11.

[0087] Furthermore, the abutting seat 41 is integrally formed; the first abutting portion 411 has a wedge-shaped structure, the second abutting portion 412 and the limiting portion 413 both have a plate-shaped structure, and the limiting portion 413 is perpendicular to the second abutting portion 412. The second abutting portion 412 is formed with an anti-slip structure 4121 to increase the friction between the filter screen 6 and the second abutting portion 412 and ensure that the filter screen 6 is firmly fixed; specifically, the sliding column 42 has a cylindrical structure.

[0088] In view of the problem of unstable movement when the first slider 3 and the second slider 4 move synchronously or relatively, in this embodiment, a first sliding hole 31 is formed inside the first slider 3, and the first sliding hole 31 is arranged close to the second slider 4; the second slider 4 further includes a sliding seat 43, the sliding seat 43 is arranged at one end of the sliding column 42 close to the first slider 3, and the sliding seat 43 is slidably arranged in the first sliding hole 31; specifically, both the sliding seat 43 and the first sliding hole 31 have a cylindrical structure;

[0089] When the filter screen 6 and the second slider 4 are in the first working state, the sliding seat 43 and the first sliding hole 31 cooperate to enable the first slider 3 and the second slider 4 to act together in the first direction, and then the first slider 3 and the second slider 4 can slide synchronously in the first direction;

[0090] When the filter screen 6 and the second slider 4 are in the fourth working state, the sliding seat 43 and the first sliding hole 31 cooperate to enable the second slider 4 to slide relative to the first slider 3 in the second direction.

[0091] In view of the problem of unreliable connection between the sliding column 42 and the abutting seat 41 and between the sliding column 42 and the sliding seat 43, in this embodiment, the second slider 4 is integrally formed, and the abutting seat 41, the sliding column 42 and the sliding seat 43 are arranged and connected in sequence; or, the sliding column 42 is connected to the abutting seat 41 and the sliding column 42 is connected to the sliding seat 43 by welding; the outer diameter of the abutting seat 41 is larger than the outer diameter of the sliding column 42, and the outer diameter of the sliding seat 43 is larger than the outer diameter of the sliding column 42; a groove for sleeving the sliding column 42 is formed between the abutting seat 41 and the sliding seat 43, and the side wall of the first sliding groove 21 forming the second sliding groove 22 is embedded in the groove; the sliding column 42 is arranged in the second sliding groove 22, and the height of the sliding column 42 is greater than the depth of the second sliding groove 22, so that the second slider 4 can move relative to the first slider 3 in the second direction.

[0092] In view of the problem of small acting force of the first slider 3 and the second slider 4 in the second direction, in this embodiment, a limiting hole 32 is further formed inside the first slider 3, and the limiting hole 32 communicates with the first sliding hole 31; the sliding assembly further includes an elastic member 51, one end of the elastic member 51 is arranged in the limiting hole 32 and abuts against the bottom wall of the limiting hole 32; the other end of the elastic member 51 is arranged in the first sliding hole 31 and abuts against the sliding seat 43; specifically, the elastic member 51 is a spring;

[0093] When the filter screen 6 and the second slider 4 are in the fourth working state, the second slider 4 slides relative to the first slider 3 in the second direction and compresses the elastic member 51. Then, the second slider 4 and the first slider 3 act together in the second direction.

[0094] When the filter screen 6 and the second slider 4 are in the second working state, the filter screen 6 abuts against the second abutting portion 412, causing the abutting seat 41 to abut against the side wall of the first sliding groove 21 where the second sliding groove 22 is formed. The elastic member 51 causes the first slider 3 to abut against the side wall of the first sliding groove 21 away from the second sliding groove 22.

[0095] Aiming at the problem of unstable movement when the first slider 3 and the second slider 4 move synchronously, in this embodiment, a second sliding hole 34 and a transition hole 33 are further formed inside the first slider 3. The second sliding hole 34 is arranged away from the second slider 4, and the second sliding hole 34 communicates with the limiting hole 32 through the transition hole 33.

[0096] The sliding assembly further includes a connecting member 52. The connecting member 52 includes a connecting head 521 and a connecting rod 522. The connecting head 521 is arranged in the second sliding hole 34. One end of the connecting rod 522 is connected to the connecting head 521, and the other end of the connecting rod 522 sequentially passes through the transition hole 33 and the elastic member 51 and is connected to the second slider 4.

[0097] When the filter screen 6 and the second slider 4 are in the first working state, the connecting member 52 connects the first slider 3 and the second slider 4. Then, the first slider 3 and the second slider 4 can slide synchronously in the first direction.

[0098] When the filter screen 6 and the second slider 4 are in the fourth working state, the sliding seat 43 slides along the first sliding hole 31, the connecting rod 522 slides along the transition hole 33, and the connecting head 521 slides along the second sliding hole 34. Then, the second slider 4 slides relative to the first slider 3 in the second direction.

[0099] Preferably, the first sliding hole 31, the limiting hole 32, the transition hole 33, and the second sliding hole 34 all extend in the second direction and are coaxially arranged in sequence; the first sliding hole 31, the limiting hole 32, the transition hole 33, and the second sliding hole 34 are all of cylindrical structures, and the aperture of the first sliding hole 31 is larger than the aperture of the limiting hole 32, the aperture of the limiting hole 32 is larger than the aperture of the transition hole 33, and the aperture of the second sliding hole 34 is larger than the aperture of the limiting hole 32.

[0100] The connecting member 52 is a bolt, and threaded holes 44 are formed in both the sliding seat 43 and the sliding column 42; the nut of the bolt is the connecting head 521, and the nut is located in the second sliding hole 34; the screw rod of the bolt is the connecting rod 522, and the other end of the screw rod is connected to the threaded hole 44; a shock absorber 53 is provided on the top of the nut, and the shock absorber 53 is made of rubber material; on the one hand, it plays a shock-absorbing role to prevent the connecting head 521 from directly colliding with the side wall of the first sliding groove 21 when the second slider 4 moves relative to the first slider 3, resulting in damage to the connecting head 521 and the side wall of the first sliding groove 21; on the other hand, it can seal the second sliding hole 34 to prevent external dust from entering the second sliding hole 34, resulting in the inability of the sliding seat 43 to slide along the first sliding hole 31, the connecting rod 522 to slide along the transition hole 33, and the connecting head 521 to slide along the second sliding hole 34.

[0101] In view of the problem that the filter screen 6 is not firmly fixed when it is fixed in the installation cavity 11, the present embodiment further proposes that the installation frame 1 includes a first frame body 111 and a second frame body 112 arranged opposite to each other; there are four guiding members 2, two guiding members 2 are respectively arranged at opposite ends of the first frame body 111, and the other two guiding members 2 are respectively arranged at opposite ends of the second frame body 112, and the first sliding groove 21 and the second sliding groove 22 of each guiding member 2 extend along the extending direction of the installation cavity 11; there are four sliding assemblies, and the four sliding assemblies are arranged in one-to-one correspondence with the four guiding members 2;

[0102] In this way, guiding the filter screen 6 from different positions can easily slide the filter screen 6 into the installation cavity 11 or slide the filter screen 6 out of the installation cavity 11; fixing the filter screen 6 from different positions can reliably fix the filter screen 6 in the installation cavity 11.

[0103] In summary, the process of installing the filter screen 6 in the installation cavity 11 is as follows:

[0104] First, make both sides of one end of the filter screen 6 respectively abut against the corresponding first abutting portions 411. At this time, the filter screen 6 and the second slider 4 are in the first working state;

[0105] Second, slide the filter screen 6 into the installation cavity 11 along the first direction. The filter screen 6 acts on the first slider 3, and the first slider 3 and the second slider 4 act together. Then, the first slider 3 and the second slider 4 slide synchronously along the first direction, and further the filter screen 6 completely slides into the installation cavity 11;

[0106] Third, make the filter screen 6 move from the first abutting portion 411 to the second abutting portion 412. At this time, the filter screen 6 and the second slider 4 are in the fourth working state, and then the first slider 3 and the second slider 4 act together along the second direction;

[0107] Fourth, make both sides of one end of the filter net 6 respectively abut against the corresponding second abutting parts 412. At this time, the filter net 6 and the second slider 4 are in the second working state. Under the action of the elastic member 51, the first slider 3 and the second slider 4 act together in the second direction and the first slider 3 is clamped in the first chute 21. Further, the filter net 6 is fixed in the installation cavity 11.

[0108] The process of disassembling and cleaning the filter net 6 from the installation cavity 11 is as follows:

[0109] First, make the filter net 6 slide in the direction opposite to the first direction.

[0110] Second, when the filter net 6 does not abut against the first abutting part 411 and the second abutting part 412, the filter net 6 and the second slider 4 are in the third working state. The filter net 6 does not act on the second slider 4, and the elastic member 51 returns to its original state, making the filter net 6 continue to slide out of the installation cavity 11 in the direction opposite to the first direction. Further, the filter net 6 can be disassembled from the installation cavity 11.

[0111] To disassemble and assemble the filter net 6, only a little force is needed to slide the filter net 6 into or out of the installation cavity 11. The disassembly and assembly process is simple, the operation intensity is low, the disassembly is rapid, and the disassembly efficiency is improved.
