DETAILED DESCRIPTION

[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] The filter is a key component provided with an air flow channel for preventing impurities from entering the air flow channel, and is used to filter dust and particulate matter in the air. Currently, the filter is generally provided in an air conditioner or in an air filter.

[0038] However, after long-term use, the filter is prone to accumulate dust, which can easily cause the air flow path to become dirty and clogged, affecting the air volume and indoor air quality. In addition, since the filter is usually installed in a pull-out manner on both sides, the unfolded length of the filter corresponding to appliances of different specifications is different, making it inconvenient to extract the filter and poor in versatility.

[0039] Based on the above technical problems, the embodiment of the utility model discloses a filtering device, which includes a filter 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, wherein the filter 1 is installed on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2. When the telescopic assembly 3 is extended and retracted, it drives the plurality of support brackets 2 to make linear motion, so as to adjust the unfolded length of the filter 1 by adjusting the spacing between two adjacent support brackets 2. Thus, the length of the filtering device can be compressed and then pulled sideways, and the required pulling space is small, and the length requirements of the filter 1 for different electrical appliances can be adapted by stretching or compressing the length of the filtering device. Thus, the convenience of disassembly and assembly of the filtering device and the versatility of the product can be improved.

[0040] Reference Figure 1-3 The embodiment of the utility model provides a filtering device, which may include a filter screen 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein:

[0041] A plurality of support brackets 2 are arranged at intervals, and the filter screen 1 is installed on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2. When the telescopic assembly 3 is extended and retracted, it drives the plurality of support brackets 2 to perform linear motion, so as to adjust the unfolded length of the filter screen 1 by adjusting the interval between two adjacent support brackets 2.

[0042] In the embodiment of the utility model, the number of the supporting brackets 2 is at least two, and the filter 1 is fixed to the supporting brackets 2. For example, the filter 1 can be fixed to the two ends of the supporting bracket 2 respectively, so that the filter 1 can be kept in an unfolded state by the supporting bracket 2. The telescopic component 3 is sleeved on a plurality of supporting brackets 2, and forms a sliding connection with each supporting bracket 2. The telescopic component 3 can extend or retract in the horizontal direction under force, so that the plurality of supporting brackets 2 embedded in the telescopic component 3 can be driven to move linearly in the horizontal direction. And by adjusting the spacing between two adjacent supporting brackets 2, the length of the filter 1 in the horizontal direction can be adjusted.

[0043] In some embodiments, when the telescopic assembly 3 is stretched and extended, the plurality of support brackets 2 are driven to move linearly in the horizontal direction, and during the extension process of the telescopic assembly 3, the distance between two adjacent support brackets 2 gradually increases, thereby driving the unfolded length of the filter net 1 on the support bracket 2 to gradually increase. Until the telescopic assembly 3 is in a fully extended state, the distance between two adjacent support brackets 2 is the largest, and the unfolded length of the filter net 1 is the longest.

[0044] When the telescopic assembly 3 is compressed and retracted, it drives the multiple supporting brackets 2 to move linearly in the horizontal direction. During the retraction process of the telescopic assembly 3, the distance between two adjacent supporting brackets 2 gradually decreases, thereby driving the expanded length of the filter screen 1 located on the supporting bracket 2 to gradually shorten, and the filter screen 1 is folded until the telescopic assembly 3 is in a fully retracted state. At this time, the distance between two adjacent supporting brackets 2 is the smallest, and the expanded length of the filter screen 1 is the shortest.

[0045] When the filter device needs to be disassembled and cleaned, the telescopic component 3 can be retracted, so that the length of the filter device can be compressed before the side is pulled out, and the required pulling space is small, and the length of the filter device can be stretched or compressed to adapt to the length requirements of different electrical appliances for the filter 1. For example, if the length of the filter 1 is required to be shorter, the telescopic component 3 can be retracted to a certain length, so that the unfolded length of the filter 1 can be shortened to adapt to different specifications or different types of electrical appliances for the length requirements of the filter 1. In this way, the convenience of disassembly and assembly of the filter device can be improved, and the product versatility of the filter device can be improved.

[0046] In summary, the embodiment of the utility model discloses a filter device, which may include a filter 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, wherein the filter 1 is mounted on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2. When the telescopic assembly 3 is extended and retracted, it drives the plurality of support brackets 2 to make linear motion, so as to adjust the unfolded length of the filter 1 by adjusting the spacing between two adjacent support brackets 2. Thus, the length of the filter device can be compressed and then pulled sideways, and the required pulling space is small, and the length requirements of the filter 1 for different electrical appliances can be adapted by stretching or compressing the length of the filter device. Thus, the convenience of disassembly and assembly of the filter device and the versatility of the product can be improved.

[0047] In an optional utility model embodiment, referring to Figure 1 and Figure 2As shown, the filtering device may include a filter 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, and the filter 1 is installed on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2, and the telescopic assembly 3 may include a plurality of connecting members 31 and a plurality of rotating structures 32. The plurality of connecting members 31 are respectively sleeved on each support bracket 2 and form a sliding connection with the support bracket 2. The two ends of each rotating structure 32 are respectively rotatably connected with the connecting members 31 on two adjacent support brackets 2, so that when the connecting member 31 slides along the support bracket 2, the rotating structure 32 is driven to move, thereby adjusting the unfolded length of the filter 1 located between two adjacent support brackets 2.

[0048] In an embodiment of the utility model, the number of the supporting brackets 2 is at least two, and the filter 1 is fixed to the supporting brackets 2. For example, the filter 1 can be fixed to the two ends of the supporting bracket 2 respectively, so that the filter 1 can be kept in an unfolded state by the supporting bracket 2. The telescopic component 3 is sleeved on a plurality of supporting brackets 2, and forms a sliding connection with each supporting bracket 2. The telescopic component 3 can extend or retract in the horizontal direction under force, so that the plurality of supporting brackets 2 embedded in the telescopic component 3 can be driven to move linearly in the horizontal direction. And by adjusting the spacing between two adjacent supporting brackets 2, the length of the filter 1 in the horizontal direction can be adjusted.

[0049] In some embodiments, when the telescopic assembly 3 is stretched and extended, the plurality of support brackets 2 are driven to move linearly in the horizontal direction, and during the extension process of the telescopic assembly 3, the distance between two adjacent support brackets 2 gradually increases, thereby driving the unfolded length of the filter net 1 on the support bracket 2 to gradually increase. Until the telescopic assembly 3 is in a fully extended state, the distance between two adjacent support brackets 2 is the largest, and the unfolded length of the filter net 1 is the longest.

[0050] When the telescopic assembly 3 is compressed and retracted, it drives the multiple supporting brackets 2 to move linearly in the horizontal direction. During the retraction process of the telescopic assembly 3, the distance between two adjacent supporting brackets 2 gradually decreases, thereby driving the expanded length of the filter screen 1 located on the supporting bracket 2 to gradually shorten. The filter screen 1 is folded until the telescopic assembly 3 is in a fully retracted state. At this time, the distance between two adjacent supporting brackets 2 is the smallest, and the expanded length of the filter screen 1 is the shortest.

[0051] Furthermore, the telescopic assembly 3 may include a plurality of connecting members 31 and a plurality of rotating structures 32. The plurality of connecting members 31 are respectively sleeved on each supporting bracket 2 and form a sliding connection with the supporting bracket 2. Among them, at most two connecting members 31 are sleeved on each supporting bracket 2. In other words, two connecting members 31 may be sleeved on each supporting bracket 2, or one connecting member 31 may be sleeved on each supporting bracket 2.

[0052] The two ends of each rotating structure 32 are respectively rotatably connected to the connecting pieces 31 on two adjacent support brackets 2. That is to say, the left end of the rotating structure 32 is rotatably connected to the connecting piece 31 on one of the two adjacent support brackets 2, and the right end of the rotating structure 32 is rotatably connected to the connecting piece 31 on the other of the two adjacent support brackets 2, so that when the connecting piece 31 slides along the support bracket 2, the rotating structure 32 is driven to move, for example, the rotating structure 32 is driven to rotate itself, so that the length of the rotating structure 32 in the horizontal direction can be shortened or extended, and the distance between the two adjacent support brackets 2 can be adjusted thereby, so that the unfolded length of the filter screen 1 between the two adjacent support brackets 2 can be adjusted.

[0053] When the filter device needs to be disassembled and cleaned, the telescopic component 3 can be retracted, so that the length of the filter device can be compressed before the side is pulled out, and the required pulling space is small, and the length of the filter device can be stretched or compressed to adapt to the length requirements of different electrical appliances for the filter 1. For example, if the length of the filter 1 is required to be shorter, the telescopic component 3 can be retracted to a certain length, so that the unfolded length of the filter 1 can be shortened to adapt to different specifications or different types of electrical appliances for the length requirements of the filter 1. In this way, the convenience of disassembly and assembly of the filter device can be improved, and the product versatility of the filter device can be improved.

[0054] In an optional embodiment of the utility model, the filter device may include a filter screen 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, and the filter screen 1 is installed on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2, and the telescopic assembly 3 may include a plurality of connectors 31 and a plurality of rotating structures 32. The connector 31 includes a first connecting portion 311 and a second connecting portion 312 located below the first connecting portion 311, wherein the first connecting portion 311 and the second connecting portion 312 are sleeved on the support bracket 2 and form a sliding connection with the support bracket 2, respectively. Moreover, the first connecting portion 311 and the second connecting portion 312 are respectively rotatably connected with the rotating structure 32, wherein when the first connecting portion 311 and the second connecting portion 312 are subjected to force to make a linear motion close to each other along the support bracket 2, the length of the rotating structure 32 is driven to extend. When the first connection portion 311 and the second connection portion 312 are forced to make a linear motion away from each other along the support bracket 2 , the length of the rotating structure 32 is shortened to adjust the unfolded length of the filter screen 1 between two adjacent support brackets 2 .

[0055] In an embodiment of the utility model, the number of the supporting brackets 2 is at least two, and the filter 1 is fixed to the supporting brackets 2. For example, the filter 1 can be fixed to the two ends of the supporting bracket 2 respectively, so that the filter 1 can be kept in an unfolded state by the supporting bracket 2. The telescopic component 3 is sleeved on a plurality of supporting brackets 2, and forms a sliding connection with each supporting bracket 2. The telescopic component 3 can extend or retract in the horizontal direction under force, so that the plurality of supporting brackets 2 embedded in the telescopic component 3 can be driven to move linearly in the horizontal direction. And by adjusting the spacing between two adjacent supporting brackets 2, the length of the filter 1 in the horizontal direction can be adjusted.

[0056] In some embodiments, when the telescopic assembly 3 is stretched and extended, the plurality of support brackets 2 are driven to move linearly in the horizontal direction, and during the extension process of the telescopic assembly 3, the distance between two adjacent support brackets 2 gradually increases, thereby driving the unfolded length of the filter net 1 on the support bracket 2 to gradually increase. Until the telescopic assembly 3 is in a fully extended state, the distance between two adjacent support brackets 2 is the largest, and the unfolded length of the filter net 1 is the longest.

[0057] When the telescopic assembly 3 is compressed and retracted, it drives the multiple supporting brackets 2 to move linearly in the horizontal direction. During the retraction process of the telescopic assembly 3, the distance between two adjacent supporting brackets 2 gradually decreases, thereby driving the expanded length of the filter screen 1 located on the supporting bracket 2 to gradually shorten. The filter screen 1 is folded until the telescopic assembly 3 is in a fully retracted state. At this time, the distance between two adjacent supporting brackets 2 is the smallest, and the expanded length of the filter screen 1 is the shortest.

[0058] Furthermore, the telescopic assembly 3 may include a plurality of connecting members 31 and a plurality of rotating structures 32. The connecting member 31 may include a first connecting portion 311 and a second connecting portion 312, wherein the first connecting portion 311 and the second connecting portion 312 are sleeved on the same supporting bracket 2. The first connecting portion 311 forms a sliding connection with the supporting bracket 2, and the second connecting portion 312 forms a sliding connection with the supporting bracket 2. Thus, the first connecting portion 311 forms a rotating connection with the rotating structure 32, and the second connecting portion 312 forms a rotating connection with the rotating structure 32.

[0059] When the first connection part 311 and the second connection part 312 are forced to move toward each other along the support bracket 2, the distance between the connection between the rotating structure 32 and the first connection part 311 and the connection between the rotating structure 32 and the second connection part 312 is shortened (it can be understood as reducing the height of the rotating structure 32 in the vertical direction), thereby driving the length of the rotating structure 32 in the horizontal direction to extend. And thereby increase the distance between two adjacent support brackets 2. For example, from Figure 1 The spacing d2 in the Figure 2 The spacing d1 in the filter screen can thereby extend the unfolded length of the filter screen 1.

[0060] When the first connection part 311 and the second connection part 312 are forced to move linearly away from each other along the support bracket 2, the distance between the connection between the rotating structure 32 and the first connection part 311 and the connection between the rotating structure 32 and the second connection part 312 is extended (which can be understood as increasing the height of the rotating structure 32 in the vertical direction), thereby shortening the length of the rotating structure 32 in the horizontal direction. And thereby shortening the distance between two adjacent support brackets 2, for example, from Figure 1 The spacing d2 in the Figure 3 The spacing d3 in the filter screen can thereby shorten the unfolded length of the filter screen 1.

[0061] When the filter device needs to be disassembled and cleaned, the telescopic component 3 can be retracted, so that the length of the filter device can be compressed before the side is pulled out, and the required pulling space is small, and the length of the filter device can be stretched or compressed to adapt to the length requirements of different electrical appliances for the filter 1. For example, if the length of the filter 1 is required to be shorter, the telescopic component 3 can be retracted to a certain length, so that the unfolded length of the filter 1 can be shortened to adapt to different specifications or different types of electrical appliances for the length requirements of the filter 1. In this way, the convenience of disassembly and assembly of the filter device can be improved, and the product versatility of the filter device can be improved.

[0062] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, the rotating structure 32 includes two support rods 321, the two support rods 321 are cross-arranged, and the intersection of the two support rods 321 forms a rotating connection. In addition, the same side of the two support rods 321 is respectively connected to the first connection part 311 and the second connection part 312 on the same support bracket 2, and the two support rods 321 rotate relatively around the intersection to adjust the unfolded length of the filter 1 between two adjacent support brackets 2.

[0063] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, the rotating structure 32 further includes a rotating pin 322, and the intersection of the two support rods 321 is rotatably connected through the rotating pin 322. The plug-in assembly of the rotating pin 322 can improve the convenience of disassembly and assembly of the rotating structure 32.

[0064] In an optional utility model embodiment, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, the filtering device further includes a connecting pin 4, and the two ends of the rotating structure 32 are rotatably connected with the connecting member 31 through the connecting pin 4. The plug-in assembly of the connecting pin 4 can improve the convenience of assembly and disassembly between the rotating structure 32 and the connecting member 31. The structures of the connecting pin 4 and the rotating pin 322 can be kept consistent. The diameter of the assembly hole pre-opened for the connecting pin 4 to pass through and the diameter of the assembly hole for the rotating pin 322 to pass through can be kept consistent.

[0065] In an optional utility model embodiment, referring to Figure 1 and Figure 2As shown, in the case where two connecting members 31 are simultaneously sleeved on the supporting bracket 2, the two first connecting portions 311 included in the two connecting members 31 are an integrated structure.

[0066] In the embodiment of the utility model, when two connecting members 31 are sleeved on the support bracket 2 at the same time, the first connecting portion 311 included in the first connecting member 31 and the first connecting portion 311 included in the second connecting member 31 can be an integrated structure. In other words, the first connecting portion 311 of the first connecting member 31 and the first connecting portion 311 of the second connecting member 31 share a sleeved portion to achieve the rotational connection of the rotating structures 32 on both sides. The integrated structure can reduce the production cost of the connecting member 31 and improve the convenience of assembly of the filtering device.

[0067] For example, the first connection part 311 may include a rotating part and a sleeve part, the rotating part extending in the horizontal direction of the sleeve part, and a rotating groove for the support rod 321 to be embedded in the rotating part is provided, so that the support rod 321 can be limited by the rotating groove to improve the rotation stability of the support rod 321. In the case where two connecting members 31 are sleeved on the support bracket 2 at the same time, the two connecting members 31 can share a sleeve part, that is, a rotating part extends from both sides of the sleeve part. Thus, the sleeve part is sleeved on the support bracket 2 and forms a sliding connection with the support bracket 2.

[0068] In an optional utility model embodiment, referring to Figure 1 and Figure 2 As shown, when two connecting members 31 are simultaneously mounted on the support bracket 2, the two second connecting portions 312 included in the two connecting members 31 are an integrated structure.

[0069] In the embodiment of the utility model, when two connecting members 31 are sleeved on the support bracket 2 at the same time, the second connecting portion 312 included in the first connecting member 31 and the second connecting portion 312 included in the second connecting member 31 can be an integrated structure. In other words, the second connecting portion 312 of the first connecting member 31 and the second connecting portion 312 of the second connecting member 31 share a sleeved portion to achieve the rotational connection of the rotating structures 32 on both sides. The integrated structure can reduce the production cost of the connecting member 31 and improve the convenience of assembly of the filtering device.

[0070] In some optional embodiments, the structures of the second connection portion 312 and the first connection portion 311 may be consistent, thereby reducing the production cost of the filtering device.

[0071] In an optional embodiment of the utility model, the first connecting portion 311, the second connecting portion 312 and the supporting rod 321 are respectively made of plastic materials.

[0072] In the embodiment of the utility model, the first connection part 311, the second connection part 312 and the support rod 321 can be respectively made of plastic materials and obtained by injection molding. The first connection part 311, the second connection part 312 and the support rod 321 can be made of the same plastic material or different plastic materials, which is not limited here.

[0073] In summary, the embodiment of the utility model discloses a filter device, which may include a filter 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, wherein the filter 1 is mounted on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2. When the telescopic assembly 3 is extended and retracted, it drives the plurality of support brackets 2 to make linear motion, so as to adjust the unfolded length of the filter 1 by adjusting the spacing between two adjacent support brackets 2. Thus, the length of the filter device can be compressed and then pulled sideways, and the required pulling space is small, and the length requirements of the filter 1 for different electrical appliances can be adapted by stretching or compressing the length of the filter device. Thus, the convenience of disassembly and assembly of the filter device and the versatility of the product can be improved.

[0077] Therefore, when it is necessary to remove the filter 1 from the fan duct body for cleaning, the support bracket 2 can be compressed from one side to give the support bracket 2 a horizontal pressure. Under the action of the horizontal pressure, the first connection part 311 and the second connection part 312 on the support bracket 2 make a linear motion away from each other on the support bracket 2, thereby reducing the distance between two adjacent support brackets 2, thereby folding the filter 1. When the support rod 321 is fully compressed, the length of the filter device in the horizontal direction is the shortest, so that the filter device can be disassembled and cleaned in a smaller push-pull space, thereby improving the convenience of disassembly and assembly of the filter device.

[0078] When the user installs the filter 1, the filter device can be pushed into the guide groove 52 and the support bracket 2 on one side can be pulled. At this time, the first connection part 311 and the second connection part 312 on the same support bracket 2 move linearly toward each other, and the two support rods 321 rotate around the intersection and extend the length of the support rods 321 in the horizontal direction, thereby increasing the distance between two adjacent support brackets 2 and unfolding the filter 1. When it is pulled to the same length as the return air outlet 51, it is determined that the filter 1 is installed.

[0079] The embodiment of the utility model further provides an air filter, which may include the filtering device as described in any one of the above-mentioned embodiments of the utility model.

[0080] In the embodiment of the utility model, the air filter refers to a device for air filtering, and the filtering device can be installed at the air inlet or the air outlet of the air filter.

[0081] In summary, the embodiment of the utility model discloses a filter device, an air conditioner and an air filter. The embodiment of the utility model may include a filter 1, a plurality of support brackets 2 and a telescopic assembly 3, wherein the plurality of support brackets 2 are arranged at intervals, wherein the filter 1 is mounted on the plurality of support brackets 2. The telescopic assembly 3 is sleeved on the plurality of support brackets 2 and forms a sliding connection with each support bracket 2. When the telescopic assembly 3 is extended and retracted, it drives the plurality of support brackets 2 to make linear motion, so as to adjust the unfolded length of the filter 1 by adjusting the spacing between two adjacent support brackets 2. Thus, the length of the filter device can be compressed and then pulled sideways, and the required pulling space is small, and the length of the filter device can be stretched or compressed to adapt to the length requirements of the filter 1 of different electrical appliances. Thus, the convenience of disassembly and assembly of the filter device can be improved and the versatility of the product can be improved.
