[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0043] Combine Figure 1-8 As shown, the embodiment of the present disclosure provides a filtering device for an air conditioner, including an air outlet frame 10, the air outlet frame 10 is provided with an air outlet 101; a foldable filter 20, one end of which is a fixed end 201, the fixed end 201 is fixed at the air outlet 101, and the other end is a free end 202, and the free end 202 is provided with a traction part 21; a track 30, which is fixed to the air outlet frame 10 corresponding to the traction part 21; and a driving member 40, which is connected to the traction part 21, and the driving member 40 moves along the track 30, wherein the driving member 40 drives the traction part 21 to move in a first direction so that the foldable filter 20 extends and blocks the air outlet 101; the driving member 40 drives the traction part 21 to move in a second direction so that the foldable filter 20 is folded to one side of the air outlet 101.

[0044] A foldable filter 20 is provided at the air outlet 101. The fixed end 201 of the foldable filter 20 is fixed to the air outlet 101, and a traction portion 21 is provided at the free end 202. The traction portion 21 is driven by a driving member 40 to move in a first direction to extend the foldable filter 20, and in a second direction to fold the foldable filter 20 to one side of the air outlet 101. The first direction is opposite to the second direction. When the foldable filter 20 is extended, it blocks the air outlet 101; when it is folded, it opens the air outlet 101. When blocked, the air outlet 101 functions as an air inlet 101; when opened, it functions as an air outlet 101. By driving the traction portion 21 to move linearly at the air outlet 101 through the driving member 40, the foldable filter 20 can realize the function of switching between air intake and return air at will, replacing the method in which the user needs to remove the filter to switch between air intake and return air. The use of the filter device provided by the embodiment of the present disclosure can make it more convenient for users to operate and improve the user experience. At the same time, this also effectively reduces the space occupied by other parts when the filter device is in use, facilitating installation while ensuring aesthetics.

[0045] Optionally, the track 30 includes a first track bar 301, which is fixed to the air outlet frame 10, and the first track bar 301 is arranged on one side of the traction part 21; and a second track bar 302, which is fixed to the air outlet frame 10, and the second track bar 302 is arranged on the other side of the traction part 21, wherein the first track bar 301 and the second track bar 302 form a sliding space, and the driving member 40 can move along the sliding space.

[0046] The driver 40 is connected to the traction section 21. The first and second track bars 301, 302 are located on either side of the traction section 21, forming a sliding space. This allows the traction section 21 to be positioned between the first and second track bars 301, 302. The driver 40 moves along the sliding space, thereby driving the traction section 21 along the sliding space, allowing the foldable filter 20 to be extended or folded. The sliding space formed by the first and second track bars 301, 302 facilitates the movement of the driver 40.

[0047] Optionally, the first track bar 301 is provided with a first guide groove, and the second track bar 302 is provided with a second guide groove, wherein a rack 3011 is provided on an outer edge of the first track bar 301 facing the second track bar 302 .

[0048] Optionally, the driving member 40 includes a fixed frame, both ends of which are slidingly connected to the first track bar 301 and the second track bar 302 respectively; a motor 42, fixed to one side of the fixed frame; and a gear 43, arranged on the other side of the fixed frame, and the gear 43 is engaged with the rack 3011, one side of the central axis of the gear 43 is fixedly connected to the output shaft of the motor 42, and the other side is provided with a sleeve 44, which is sleeved on the traction part 21.

[0049] The first track bar 301 and the second track bar 302 are respectively provided with a first guide groove and a second guide groove. The two ends of the fixed frame are respectively slidably connected to the first track bar 301 and the second track bar 302, that is, the two ends of the fixed frame are respectively engaged with the first guide groove and the second guide groove, and move along the first guide groove and the second guide groove. The first track bar 301 and the second track bar 302 are respectively provided with a first guide groove and a second guide groove, which not only provides a sliding condition for the fixed frame, but also acts as a limit, allowing the fixed frame to move along the guide groove. A rack 3011 is provided on the outer edge of the first track bar 301 facing the second track bar 302, and a gear 43 is engaged with the rack 3011. One side of the central axis of the gear 43 is fixedly connected to the output shaft of the motor 42, and the other side is provided with a shaft sleeve 44, which is sleeved on the traction part 21. In this way, the motor 42 drives the gear 43 to rotate, and the gear 43 moves along the rack 3011. As the gear 43 rotates, the sleeve 44, located on the other side of the central axis of the gear 43, rotates. Since the sleeve 44 is sleeved on the traction part 21 and is not directly connected to the traction part 21, the rotation of the sleeve 44 is effectively prevented from causing the traction part 21 to rotate, thereby damaging the foldable filter 20. When the gear 43 moves along the rack 3011, it also causes the traction part 21 to move, thereby enabling the foldable filter 20 to achieve different usage states.

[0050] Optionally, the first guide groove and the second guide groove can be through grooves or non-through grooves, as long as the two ends of the fixing frame can be respectively clamped in the first guide groove and the second guide groove, and can serve as a limit for the fixing frame without affecting the sliding of the fixing frame, the setting form is not specifically limited here.

[0051] Optionally, the fixing frame includes a fixing plate 411; a first limiting rod 412, fixedly connected to one end of the fixing plate 411, and the first limiting rod 412 is slidably connected to the first track bar 301; and a second limiting rod 413, fixedly connected to the other end of the fixing plate 411, and the second limiting rod 413 is slidably connected to the second track bar 302.

[0052] The fixing plate 411 is used to secure the motor 42 and gear 43. Specifically, the motor 42 is secured to one side of the fixing plate 411, and the gear 43 is secured to the other side of the motor 42. The fixing plate 411, along with the motor 42 and gear 43 secured to either side of the fixing plate 411, is positioned within the sliding space formed by the first track bar 301 and the second track bar 302, thereby driving the traction unit 21 to move. A first limiting rod 412 and a second limiting rod 413 are respectively disposed at each end of the fixing plate 411, allowing the first limiting rod 412 to slideably connect to the first track bar 301, and the second track bar 302 to slideably connect to the second track bar 302. This effectively prevents the motor 42 from shaking during rotation, which could affect the normal operation of the filter device.

[0053] Optionally, the first limiting rod 412 is provided with a first sliding portion 4121, which is clamped in the first guide groove and is used to make the first limiting rod 412 slide in the first guide groove; the second limiting rod 413 is provided with a second sliding portion 4131, which is clamped in the second guide groove and is used to make the second limiting rod 413 slide in the second guide groove.

[0054] The first sliding portion 4121 and the second sliding portion 4131 are respectively engaged with the first guide groove and the second guide groove, thereby limiting the first limiting rod 412 and the second limiting rod 413, respectively. This effectively prevents the first limiting rod 412 and the second limiting rod 413 from shifting when sliding in the first guide groove and the second guide groove, respectively, which could cause the fixed plate 411 to tilt. This would not only affect the normal transmission of the filter device, but could even cause damage to components. The first sliding portion 4121 and the second sliding portion 4131 are respectively engaged with the first guide groove and the second guide groove, effectively ensuring the smooth movement of the fixed plate 411.

[0055] Optionally, the diameter of the first sliding portion 4121 is smaller than the diameter of other portions of the first limiting rod 412 , and the diameter of the second sliding portion 4131 is smaller than the diameter of other portions of the second limiting rod 413 .

[0056] In this way, a clamping edge will be formed at both ends of the first sliding part 4121 and the second sliding part 4131, which can further improve the limiting effect when the first sliding part 4121 and the second sliding part 4131 are respectively clamped in the first guide groove and the second guide groove, thereby improving the smoothness of the movement of the fixed plate 411.

[0057] Optionally, both the first sliding portion 4121 and the second sliding portion 4131 are sleeved with shaft sleeves.

[0058] Driven by the motor 42, the first sliding part 4121 and the second sliding part 4131 slide in the first guide groove and the second guide groove, respectively. If the first sliding part 4121 and the second sliding part 4131 are in direct contact with the first guide groove and the second guide groove, respectively, friction will be generated between the first sliding part 4121 and the second sliding part 4131 when they move. After long-term operation, long-term friction will cause varying degrees of wear on the first sliding part 4121, the second sliding part 4131, the first guide groove and the second guide groove. When the wear reaches a certain level, the parts need to be replaced, which in turn causes inconvenience to the user and affects the user's experience. Based on this, the first sliding part 4121 and the second sliding part 4131 are both provided with shaft sleeves. In this way, the wear between the first sliding part 4121 and the first guide groove, and between the second sliding part 4131 and the second guide groove can be effectively reduced.

[0059] Optionally, an oil groove is provided on the inner wall of the sleeve.

[0060] In this way, lubricating oil is placed in the oil groove, and the sliding part and the sleeve are lubricated by the lubricating oil, which can effectively extend the service life of the parts.

[0061] Optionally, traction parts 21 are provided at both ends of the free end 202 .

[0062] In this way, the driving member 40 drives the traction parts 21 at both ends of the free end 202 simultaneously, thereby ensuring the smooth movement of the foldable filter 20.

[0063] Optionally, the foldable filter 20 includes a first filter unit 22, the first filter unit 22 includes a first side surface and a second side surface 221, the first side surface includes a first end and a second end 222, the second side surface 221 includes a third end 223 and a fourth end 224, and the first end is provided with a first rotating shaft 225; the second filter unit 23 includes a third side surface and a fourth side surface 231, the third side surface includes a fifth end and a sixth end 232, the fourth side surface 231 includes a seventh end and an eighth end 233, and the seventh end is provided with a second rotating shaft 234; wherein the first filter unit 22 is arranged at the air outlet 101, and the first end is connected to the air outlet frame 10 The fourth end 224 of the first filter unit 22 is hinged to the seventh end of the second filter through the first rotating shaft 225, and the first side surface is opposite to the second side surface 221, the third side surface is opposite to the fourth side surface 231, the first end is opposite to the second end 222, the third end 223 is opposite to the fourth end 224, the fifth end is opposite to the sixth end 232, and the seventh end is opposite to the eighth end 233. When the foldable filter 20 is in the extended state, the first end, the second end 222, the fifth end and the sixth end 232 are located in the same plane, and the third end 223, the fourth end 224, the seventh end and the eighth end 233 are located in the same plane.

[0064] The first end of the first filter unit 22 is hinged to the air outlet frame 10 via a first rotating shaft 225. Specifically, the first end is provided with the first rotating shaft 225, and a shaft sleeve 44 is provided at the position of the air outlet frame 10 corresponding to the first rotating shaft 225. The first rotating shaft 225 is sleeved on the shaft sleeve 44, so that the first filter rotating unit can be rotated relative to the air outlet frame 10, facilitating the extension and folding of the foldable filter 20. The seventh end of the second filter unit 23 is provided with a second rotating shaft 234. The second filter unit 23 needs to be connected to the first filter unit 22. Furthermore, the fourth end 224 of the first filter unit 22 corresponding to the second rotating shaft 234 is provided with a shaft sleeve 44. The second rotating shaft 234 is sleeved on the shaft sleeve 44 to achieve rotation between the first filter unit 22 and the second filter unit 23. When the foldable filter 20 is in the extended state, the first end, the second end 222, the fifth end, and the sixth end 232 are located in the same plane, and the third end 223, the fourth end 224, the seventh end, and the eighth end 233 are located in the same plane. Furthermore, when the foldable filter 20 is in the extended state, the first rotating shaft 225 and the second rotating shaft 234 are located on opposite sides. In this way, the rotation direction of the first rotating shaft 225 can be opposite to the rotation direction of the second rotating shaft 234, thereby allowing the second filter unit 23 and the first filter unit 22 to be folded into the air outlet frame 10. This effectively prevents the first filter unit 22 and the second filter unit 23 from extending out of the air outlet frame 10 due to the same rotation direction, thereby damaging the aesthetics of the filter device and occupying the external space of the filter device.

[0065] Optionally, one end of the first hinge is fixed to the first end of the first filter unit 22, and the other end of the first hinge is fixed to the air outlet frame 10; one end of the second hinge is fixed to the seventh end of the second filter unit 23, and the other end of the second hinge is fixed to the fourth end 224 of the first filter unit 22. In this way, the hinged connection of the first hinge and the second hinge enables rotation between the first filter unit 22 and the air outlet frame 10, and between the first filter unit 22 and the second filter unit 23. Alternatively, other hinged connection methods may be used, which are not specifically limited here.

[0066] Optionally, a plurality of the first filter unit 22 and the second filter unit 23 are provided, the plurality of first filter units 22 and the plurality of second filter units 23 are alternately provided, and the first filter unit 22 and the second filter unit 23 are hinged in sequence.

[0067] When there are multiple first filter units 22 and multiple second filter units 23, the multiple first filter units 22 and the multiple second filter units 23 are alternately arranged, and the first filter units 22 and the second filter units 23 are hinged in sequence. Specifically, the first filter unit, that is, the first first filter unit 22, the first end of the first first filter unit 22 is hinged to the air outlet frame 10 through the first rotating shaft 225, the second filter unit, that is, the first second filter unit 23, the seventh end of the first second filter unit 23 is hinged to the fourth end 224 of the first first filter unit 22 through the second rotating shaft 234; the third filter unit, that is, the second first filter unit 22, the first end of the second first filter unit 22 is hinged to the sixth end 232 of the first second filter unit 23 through the first rotating shaft 225; the fourth filter unit, that is, the second second filter unit The seventh end of the second second filter unit 23 is hinged to the fourth end 224 of the second first filter unit 22 via a second rotating shaft 234. The first end of the fifth filter unit, i.e., the third first filter unit 22, is hinged to the sixth end 232 of the second second filter unit 23 via a first rotating shaft 225. Similarly, this connection ensures that when the foldable filter 20 is in the extended state, the multiple first rotating shafts 225 are located on the same side, and the multiple second rotating shafts 234 are located on the same side, opposite to the side where the multiple first rotating shafts 225 are located. This ensures that the rotation directions of each two adjacent filter units are opposite, allowing the foldable filter 20 composed of the multiple first filter units 22 and the multiple second filter units 23 to be folded within the air outlet frame 10. This effectively prevents the first and second filter units 22, 23 from extending out of the air outlet frame 10 due to the same rotation directions, thereby damaging the aesthetics of the filter device and occupying the external space of the filter device. At the same time, when the foldable filter 20 is in the extended state, the multiple first rotating shafts 225 are located on the same side, and the multiple second rotating shafts 234 are located on the same side, opposite the side where the multiple first rotating shafts 225 are located. As the gap between the first filter unit 22 and the second filter unit 23 decreases, the maximum rotation angle of the first rotating shaft 225 and the second rotating shaft 234 approaches 180 degrees. If rotation continues, the two opposing sides of the first filter unit 22 and the second filter unit 23 will contact, causing the first rotating shaft 225 and the second rotating shaft 234 to stop rotating. This ensures that when the foldable filter 20 is in the extended state, the foldable filter 20 is as flat as possible, allowing all air entering the filter device from the air outlet 101 to be filtered, effectively improving the filtering effect of the filter device.

[0068] Optionally, the first filter unit 22 and the second filter unit 23 are detachably connected to each other so that the foldable filter 20 can match air outlets 101 of different sizes.

[0069] In this way, the foldable filter 20 is modularized, and by increasing or decreasing the number of the first filter unit 22 or the second filter unit 23, the foldable filter 20 formed by splicing the first filter unit 22 and the second filter unit 23 can match air outlets 101 of different sizes. For example, when the air outlet 101 is too small, only one first filter unit 22 and the second filter unit 23 can be spliced ​​together to cover the entire air outlet. When the air outlet 101 is too large, multiple first filter units 22 and second filter units 23 can be alternated in sequence. According to the size of the air outlet 101, the filter units can be flexibly installed or removed, as long as it is ensured that the foldable filter 20 can cover the entire air outlet 101 when it is in the extended state. In this way, materials can be effectively saved, and thus costs can be saved.

[0070] At the same time, by setting the number of the first filter unit 22 and the second filter unit 23 according to the size of the air outlet 101, the filter device can achieve the best filtering effect. For example, when fewer filter units are installed, the entire air outlet 101 cannot be covered, and the air entering the filter device cannot be completely filtered. Impurities will still enter the filter device through the position where no filter unit is set, and the foldable filter 20 will not achieve a good filtering effect. When more filter units are installed, when the drive member 40 slides to the extreme position of the sliding space, all the filter units still cannot be extended. This will result in gaps in the filter units of the folded part. Similarly, the air entering the filter device cannot be completely filtered, and impurities will still enter the filter device through the gaps, and the foldable filter 20 will not achieve a good filtering effect.

[0071] The detachable connection between the first filter unit 22 and the second filter unit 23 can also facilitate users to clean the foldable filter 20.

[0072] Optionally, the foldable filter screen 20 further includes a sealing strip provided at the free end 202 of the foldable filter screen 20 and two side edges connected to the free end 202 .

[0073] When the foldable filter 20 is extended, a gap inevitably exists between the free end 202 of the foldable filter 20 and the two sides connected to the free end 202, and the air outlet 101. Sealing strips are provided on the free end 202 and the two sides connected to the free end 202 of the foldable filter 20 to block the gap. In this way, the edges of the foldable filter 20 are sealed, so that air can only enter the air outlet through the foldable filter 20, effectively improving the filtering effect of the foldable filter 20.

[0074] Optionally, a traction portion 21 is provided at both ends of each filter unit.

[0075] In this way, when different numbers of filter units are provided according to the size of the air outlet 101 , the traction portion 21 can be connected via the driving member 40 to drive the movement of the filter units.

[0076] Optionally, the foldable filter 20 further includes a sealing device, which is arranged on both sides of the foldable filter 20, and one end of the sealing device is a fixed part fixed at the air outlet 101, and the other end is a free part connected to the free end 202 of the foldable filter 20.

[0077] The sealing device moves with the movement of the foldable filter 20. The driving member 40 drives the traction portion 21, which in turn drives the foldable filter 20 and the sealing device. When the foldable filter 20 is in the extended state, the sealing device is also in the extended state, sealing the edge of the foldable filter 20. When the foldable filter 20 is in the folded state, the sealing device is also in the folded state, not occupying the ventilation area of ​​the air outlet 101. This further ensures the sealing effect, allowing air to enter the air outlet only through the foldable filter 20, effectively improving the filtering effect of the foldable filter 20.

[0078] An embodiment of the present disclosure further provides an air conditioner, comprising the above-mentioned filtering device for an air conditioner.

[0079] When the air conditioner is provided with a plurality of air outlets 101 , a filter device for the air conditioner is provided at each air outlet 101 , so that the air outlet and return air functions of the air outlet 101 can be flexibly switched.
