[0069] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0070] The following is for reference. Figures 1-21 A filtration device 100 according to an embodiment of the present invention is described.

[0071] like Figures 1-21 As shown, the filtration device 100 according to an embodiment of the present invention includes: a mounting frame 10, a filter screen 20, a humidifying component 30, a scraping component 40, and a driving component 50. The filter screen 20 can be disposed on the mounting frame 10. The clothing processing device (such as a dryer) can circulate air to the clothing. The mounting frame 10 can be disposed inside the clothing processing device, so that the filter screen 20 is located in the airflow path, that is, the lint on the clothing can flow through the filter screen 20 with the airflow, thereby achieving the filtration of lint and preventing a large amount of lint from accumulating in the airflow path. This is beneficial to ensuring the circulating air volume in the clothing processing device and to ensuring the working performance of the clothing processing device.

[0072] The scraper 40 can be mounted on the mounting bracket 10. The scraper 40 can move relative to the filter screen 20 to scrape the filter screen 20. That is, the scraper 40 can move to scrape off the lint on the filter screen 20, which can clean the filter screen 20 and prevent a large amount of lint from accumulating on the filter screen 20. This can ensure the filtration effect and ventilation of the filter screen 20, ensure the circulating air volume in the clothing treatment device, ensure the working performance of the clothing treatment device, and prevent lint from causing secondary pollution to the clothing due to continuous airflow, thereby improving the treatment effect on the clothing.

[0073] The drive assembly 50 can be mounted on the mounting bracket 10, and the drive assembly 50 can be connected to the scraper 40. The drive assembly 50 can drive the scraper 40 to move relative to the filter screen 20 to scrape the filter screen 20. That is, the drive assembly 50 can drive the scraper 40 to scrape off the lint on the filter screen 20, which can realize automatic cleaning of the filter screen 20, which is convenient to operate. The scraper 40 can be located in the airflow direction of the filter screen 20 (e.g., ...). Figure 1 One side of the front-back direction (as shown) Figure 1 (As shown on the front side), it can increase the contact range between the scraper 40 and the filter screen 20, which is beneficial to improving the cleaning effect on the filter screen 20.

[0074] The humidifying component 30 can spray water or water mist onto the surface of the filter screen 20 to humidify the surface of the filter screen 20. That is, the humidifying component 30 can humidify the lint on the surface of the filter screen 20, which can reduce the generation of static electricity, making it easier for lint to detach from the filter screen 20. It can also prevent lint from flying or floating when scraped by the scraping component 40, and prevent lint from re-accumulating on the filter screen 20 and the airflow path after scraping by the scraping component 40. It can also make the lint easily form larger clumps when scraped by the scraping component 40, making it easier for the scraping component 40 to scrape off the lint on the filter screen 20. This can improve the cleaning effect of the filter screen 20, ensure the filtration effect and ventilation of the filter screen 20, ensure the working performance of the clothing treatment device, and prevent lint from causing secondary pollution to clothing, thus improving the treatment effect of clothing.

[0075] Understandably, the humidifying component 30 can spray high-speed water onto the surface of the filter screen 20 to wash away lint and debris, thereby improving the cleaning effect on the filter screen 20 and reducing the working pressure on the scraper component 40. This prevents the scraper component 40 from sticking to and accumulating a large amount of lint and debris due to repeated scraping of the filter screen 20, and also prevents the scraper component 40 from causing secondary pollution to the filter screen 20 due to the accumulation of a large amount of lint and debris, thus facilitating maintenance.

[0076] According to the filtration device 100 of the present invention, by providing a filter screen 20, lint can be filtered, preventing lint from accumulating in large quantities in the airflow path. Furthermore, by providing a scraper 40 to scrape off the lint on the filter screen 20, the filter screen 20 can be cleaned, preventing lint from accumulating in large quantities on the filter screen 20. Additionally, by providing a humidification component 30 to humidify the surface of the filter screen 20, lint on the surface of the filter screen 20 can be humidified, facilitating the scraper 40 to scrape off the lint on the filter screen 20, thus improving the cleaning effect of the filter screen 20. This ensures the filtration effect and ventilation of the filter screen 20, guarantees the circulating air volume within the clothing processing device, ensures the working performance of the clothing processing device, prevents secondary pollution of clothing by lint, improves the processing effect of clothing, and enhances the user experience.

[0077] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the scraper 40 may have a first state and a second state. When the scraper 40 is in the first state, the scraper 40 can be attached to the filter screen 20, and the scraper 40 can be positioned relative to the filter screen 20 along a first direction (e.g., ...). Figure 5 The up-down direction shown allows the scraper 40 to scrape the filter screen 20 to remove lint, thus cleaning the filter screen 20. The first direction can be parallel to the plane where the filter screen 20 is located, which can increase the contact range between the scraper 40 and the filter screen 20 and improve the cleaning effect of the filter screen 20.

[0078] When the scraper 40 is in the second state, the scraper 40 can be separated from the filter screen 20, which can prevent the water sprayed by the humidification component 30 onto the filter screen 20 from directly impacting the scraper 40. This is beneficial for the humidification component 30 to spray water or water mist onto the surface of the filter screen 20 to fully humidify the lint, which can ensure the cleaning effect on the filter screen 20. At the same time, it can prevent the water sprayed by the humidification component 30 from splashing away from the filter screen 20 due to impacting the scraper 40, which can reduce water waste.

[0079] The scraper 40 can switch between a first state and a second state to allow the scraper 40 to adhere to or separate from the filter screen 20. The drive assembly 50 can drive the scraper 40 to switch between the first state and the second state. The drive assembly 50 can cooperate with the humidification assembly 30 to stagger the humidification time of the humidification work of the humidification assembly 30 on the filter screen 20 and the scraping time of the scraper 40 on the filter screen 20. It can also allow the humidification assembly 30 and the scraper 40 to avoid each other when they are working, thereby achieving automatic cleaning of the filter screen 20 and facilitating operation.

[0080] The humidifying component 30 can start working when the scraper 40 is in the second state or when it switches from the first state to the second state. That is, the humidifying component 30 can spray water onto the filter screen 20 to moisten the lint when the scraper 40 is separated from the filter screen 20. The humidifying component 30 can also stop working when the scraper 40 is in the first state or when it switches from the second state to the first state. That is, the scraper 40 can scrape the filter screen 20 after the humidifying component 30 has moistened the lint or when it has stopped working, so as to scrape off the moist lint on the filter screen 20. This makes it easier for the lint to detach from the filter screen 20, and makes it easier for the scraper 40 to form larger clumps when scraping, which makes it easier for the scraper 40 to scrape off the lint on the filter screen 20 and improves the cleaning effect on the filter screen 20.

[0081] Understandably, in the initial state, the scraper 40 can be in the second state, and the humidifying component 30 can spray water onto the filter screen 20 to moisten the lint. When the humidifying component 30 stops working, the driving component 50 can drive the scraper 40 to move and switch from the second state to the first state, so that the scraper 40 scrapes off the lint on the filter screen 20. The driving component 50 can also drive the scraper 40 to continue moving and switch from the first state to the second state. At this time, the humidifying component 30 can spray water onto the filter screen 20 again to perform a secondary cleaning of the filter screen 20, which can improve the cleaning effect of the filter screen 20. In addition, the surface of the filter screen 20 can be sprayed with a hydrophobic coating, so that the water on the filter screen 20 can more easily slide off the filter screen 20, which can ensure the ventilation effect of the filter screen 20 and ensure the working performance of the clothing treatment device.

[0082] like Figure 1 , Figure 2 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the humidifying component 30 may have a nozzle 311. The humidifying component 30 can spray water or water mist onto the filter screen 20 through the nozzle 311 to humidify the filter screen 20. The nozzle 311 may be arranged adjacent to the edge of the filter screen 20, which can increase the humidification range of the filter screen 20 and ensure that the humidifying component 30 fully humidifies every piece of lint on the filter screen 20, so that the scraper 40 can more thoroughly scrape off the lint on the filter screen 20 and improve the cleaning effect of the filter screen 20.

[0083] When the scraper 40 is in the second state, the projection of the nozzle 311 in the plane perpendicular to the first direction can be located between the scraper 40 and the filter screen 20. This can prevent the water sprayed by the humidification component 30 onto the filter screen 20 from directly impacting the scraper 40. It is beneficial for the humidification component 30 to spray water or water mist onto the surface of the filter screen 20 to fully humidify the lint, which can ensure the cleaning effect on the filter screen 20. At the same time, it can prevent the water sprayed by the humidification component 30 from splashing away from the filter screen 20 due to impacting the scraper 40, which can reduce water waste.

[0084] like Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the scraper 40 may have a slider 411, and the mounting bracket 10 may have a groove 121; or, the scraper 40 may have a groove 121, and the mounting bracket may have a slider 411, which can slide in conjunction with the groove 121, and the slider 411 can slide along the extending direction of the groove 121. At least a portion of the groove 121 can slide along a first direction (e.g., Figure 2 The scraper 40 extends in the vertical direction shown, so that the scraper 40 can be in contact with the filter screen 20 when the slider 411 and the part of the groove 121 extending in the first direction are in sliding engagement. That is, the slider 411 can be in sliding engagement with the part of the groove 121 extending in the first direction when the scraper 40 is in the first state, which is beneficial for the scraper 40 to move to scrape off the lint on the filter screen 20.

[0085] The entire slide groove 121 can extend along the first direction, so that the scraper 40 can be in contact with the filter screen 20 when it is in sliding engagement with the slide groove 121. That is, the slider 411 can be in sliding engagement with the slide groove 121 when the scraper 40 is in the first state, so that the slider 411 can disengage from the slide groove 121 to separate the scraper 40 from the filter screen 20. In other words, the slider 411 can disengage from the slide groove 121 to switch the scraper 40 from the first state to the second state. This can ensure the reliability of the scraper 40 switching between the first state and the second state, and facilitate the processing of the slide groove 121.

[0086] Alternatively, a portion of the groove 121 can extend along the first direction, so that the scraper 40 can be in contact with the filter screen 20 when the slider 411 slides with the portion of the groove 121 extending along the first direction. That is, the slider 411 can slide with the portion of the groove 121 extending along the first direction when the scraper 40 is in the first state. This allows the slider 411 to slide along the extension direction of the groove 121, thereby enabling the scraper 40 to switch between the first state and the second state. This ensures the stability of the scraper 40 switching between the first state and the second state and makes the switching of the scraper 40 between the first state and the second state smoother.

[0087] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the mounting bracket 10 may have a groove 121, and the scraper 40 may have a slider 411. The slider 411 can slide and engage with the groove 121, thereby achieving a sliding connection between the scraper 40 and the mounting bracket 10. The groove 121 may include a first groove segment 1211 and a second groove segment 1212. The first groove segment 1211 can be along a first direction (e.g., ...). Figure 2 Extending in the vertical direction (as shown), the scraper 40 can fit against the filter screen 20 when the slider 411 and the first groove 1211 slide together, so that the scraper 40 can move to scrape the filter screen 20 to remove the lint on the filter screen 20.

[0088] The second slot 1212 can be positioned away from the first slot 1211 (e.g., ... Figure 2 As shown in the bottom-to-top direction, the second groove segment 1212 gradually deviates from the filter screen 20, that is, the second groove segment 1212 can gradually move away from the filter screen 20 in a direction away from the first groove segment 1211 (e.g., from bottom to top). Figure 2 As shown in the direction from back to front, the scraper 40 extends obliquely, so that the slider 411 can be separated from the filter screen 20 when it is in sliding engagement with the second groove segment 1212, which is beneficial for the humidification assembly 30 to spray water or water mist onto the surface of the filter screen 20 to fully humidify the lint.

[0089] When the scraper 40 is in the first state, the slider 411 of the scraper 40 can slide and engage with the first groove 1211, allowing the scraper 40 to fit against the filter screen 20 and allowing the scraper 40 to move relative to the filter screen 20 along a first direction (e.g., Figure 5 The scraper 40 moves in the up-down direction (as shown), so that it can scrape the filter screen 20 to remove the lint on the filter screen 20, thereby cleaning the filter screen 20.

[0090] When the scraper 40 is in the second state, the slider 411 of the scraper 40 can cooperate with the second groove 1212, so that the scraper 40 can be separated from the filter screen 20. This prevents the water sprayed by the humidification component 30 onto the filter screen 20 from directly impacting the scraper 40. It also helps the humidification component 30 to spray water or water mist onto the surface of the filter screen 20 to fully humidify the lint, ensuring the cleaning effect on the filter screen 20. At the same time, it prevents the water sprayed by the humidification component 30 from splashing away from the filter screen 20 due to impacting the scraper 40, thus reducing water waste.

[0091] And the second slot segment 1212 can be connected to one end of the first slot segment 1211 (e.g. Figure 2 The upper end shown is connected, allowing the slider 411 to slide from the first groove 1211 into the second groove 1212 and slide into the second groove 1212, which facilitates the switching of the scraper 40 between the first and second states, so that the scraper 40 can be attached to or separated from the filter screen 20. At the same time, it can ensure the stability of the scraper 40 in switching between the first and second states, and make the switching of the scraper 40 between the first and second states smoother.

[0092] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the second groove segment 1212 can be a straight groove segment, which can ensure the reliability of the sliding engagement between the slider 411 of the scraper 40 and the second groove segment 1212, and facilitate the processing of the groove 121. Alternatively, the second groove segment 1212 can be an arc-shaped groove segment, which can make the sliding engagement between the slider 411 of the scraper 40 and the second groove segment 1212 smoother. The second groove segment 1212 and the first groove segment 1211 can be connected by an arc transition, which is beneficial for the scraper 40 to switch between the first state and the second state, so that the scraper 40 can be attached to or separated from the filter screen 20. At the same time, it can ensure the stability of the scraper 40 switching between the first state and the second state, and make the switching between the first state and the second state smoother.

[0093] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, the drive assembly 50 may include a drive motor 51 and a belt drive mechanism 52. The drive motor 51 can be connected to the scraper 40 via the belt drive mechanism 52. That is, by using a belt drive, the direction of movement of the scraper 40 can be matched with the extension direction of the groove 121, thereby making the sliding fit between the slider 411 of the scraper 40 and the groove 121 smoother and the movement of the scraper 40 smoother.

[0094] The belt drive mechanism 52 may include a driving pulley 521, a driven pulley 522, and a drive belt 523. The driving pulley 521 and the driven pulley 522 may be in a first direction (e.g., Figure 7 Arranged in the vertical direction as shown, the driving pulley 521 and the driven pulley 522 can be located on the same side of the slide groove 121 (e.g., in the vertical direction). Figure 7 (As shown on the right), the transmission belt 523 can be sleeved on the outer periphery of the driving pulley 521 and the driven pulley 522 to form a ring, and the driving pulley 521 and the driven pulley 522 can be connected by the transmission belt 523.

[0095] This allows the rotation of the driving pulley 521 to drive the annular transmission belt 523 to rotate around the driving pulley 521 and the driven pulley 522, and allows the driven pulley 522 to rotate together with the driving pulley 521 under the transmission of the transmission belt 523. The driving pulley 521 and the driven pulley 522 can be located on opposite sides of the inner circumference of the annular transmission belt 523 (e.g., Figure 7 (As shown on the upper and lower sides), it can improve the stability of the connection between the driving pulley 521 and the driven pulley 522 through the transmission belt 523, and can improve the stability of the movement of the transmission belt 523.

[0096] The transmission belt 523 can be connected to the scraper 40, and the slider 411 of the scraper 40 can slide and engage with the groove 121, so that the movement of the transmission belt 523 can drive the scraper 40 to move along the extension direction of the groove 121, which can improve the stability of the movement of the scraper 40 and allow the scraper 40 to switch between a first state and a second state. For example, the scraper 40 in the first state can slide along the extension direction of the first groove 1211 under the drive of the transmission belt 523, and the scraper 40 can slide from the first groove 1211 into the second groove 1212 and slide and engage with the second groove 1212 to enter the second state. Alternatively, the scraper 40 in the second state can slide along the extension direction of the second groove 1212 under the drive of the transmission belt 523, and the scraper 40 can slide from the second groove 1212 into the first groove 1211 and slide and engage with the first groove 1211 to enter the second state.

[0097] The drive motor 51 can be connected to the drive pulley 521 to drive the drive pulley 521 to rotate, so as to drive the driven pulley 522 to rotate together through the transmission belt 523 and drive the scraper 40 to move. This enables the automatic movement of the scraper 40 and the automatic switching of the scraper 40 between the first and second states, thus enabling automatic cleaning of the filter screen 20. At the same time, the drive pulley 521 and the driven pulley 522, which rotate together, can make the transmission belt 523 rotate more stably around the drive pulley 521 and the driven pulley 522, thereby improving the stability of the scraper 40's movement and the stability of cleaning the filter screen 20.

[0098] Furthermore, since the driving pulley 521 and the driven pulley 522 are located on opposite sides of the inner circumference of the annular transmission belt 523, the shape of the annular transmission belt 523 can be adjusted by adjusting the distance between the driving pulley 521 and the driven pulley 522. This ensures that the extension direction of a portion of the annular transmission belt 523 is approximately the same as the extension direction of a portion of the groove 121, and that the slider 411 of the scraper 40 moves along the extension direction of the groove 121 under the transmission of the transmission belt 523.

[0099] This allows for smoother movement of the scraper 40 and smoother switching between the first and second states, improving the stability of the scraper 40's movement and the stability of cleaning the filter 20. Furthermore, by increasing the distance between the drive pulley 521 and the driven pulley 522, the transmission belt 523 can be tightened, preventing it from disengaging from the drive pulley 521 and driven pulley 522 during movement. This improves the reliability of the transmission belt 523's movement, as well as the reliability of the scraper 40's movement and the reliability of cleaning the filter 20.

[0100] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the outer periphery of the driving pulley 521 may have a first transmission tooth, and the outer periphery of the driven gear may also have a first transmission tooth. The transmission belt 523 may be sleeved on the outer periphery of the driving pulley 521 and the driven pulley 522 to form an annular shape. The inner periphery of the annular transmission belt 523 may have a second transmission tooth, which may mesh with the first transmission tooth. This allows the rotation of the driving pulley 521 to drive the annular transmission belt 523 to rotate around the driving pulley 521 and the driven pulley 522. The driven pulley 522 may rotate together with the driving pulley 521 under the transmission of the transmission belt 523. The driving pulley 521 and the driven pulley 522 may be located on opposite sides of the inner periphery of the annular transmission belt 523, thereby improving the stability of the transmission connection between the driving pulley 521 and the driven pulley 522 through the transmission belt 523 and improving the stability of the movement of the transmission belt 523.

[0101] The scraper 40 may have a limiting groove 412, into which a portion of the transmission belt 523 may extend, thereby limiting the transmission belt 523 and preventing it from disengaging from the scraper 40 during movement. This improves the reliability of the movement of the transmission belt 523 and the scraper 40. Furthermore, the groove wall of the limiting groove 412 may have mating teeth that can connect with the second transmission teeth to connect the transmission belt 523 and the scraper 40. Thus, the movement of the transmission belt 523 can drive the scraper 40 to move and scrape the filter screen 20, thereby cleaning the filter screen 20.

[0102] The mating teeth can be set on one side of the limiting groove 412 (e.g.) Figure 11 On the front side (as shown), the inner circumference of the annular transmission belt 523 may have a second transmission tooth on the groove wall, which can mesh with the mating tooth, and the outer circumference of the annular transmission belt 523 may mesh with the other side (e.g., the front side) of the limiting groove 412. Figure 11 The rear side of the groove wall (as shown) is in contact with the groove wall, which can ensure the limiting effect of the transmission belt 523, prevent the transmission belt 523 from separating from the scraper 40 when it is moving, and ensure the connection effect between the transmission belt 523 and the scraper 40, thereby improving the reliability and stability of the movement of the transmission belt 523 and the scraper 40.

[0103] like Figure 7As shown, in some embodiments, the drive motor 51 can be connected to the belt drive mechanism 52 via the gear transmission mechanism 60, which is beneficial for adjusting the rotational speed of the drive pulley 521, thereby facilitating the adjustment of the movement speed of the transmission belt 523 and the scraper 40. The gear transmission mechanism 60 may include a first gear 61 and a second gear 62. The drive motor 51 can be connected to the first gear 61, so that the first gear 61 can rotate synchronously with the output shaft of the drive motor 51.

[0104] The second gear 62 can be connected to the drive pulley 521, so that the second gear 62 can rotate synchronously with the drive pulley 521. The second gear 62 can also be connected to the first gear 61, that is, the second gear 62 can mesh with the first gear 61. Thus, the drive motor 51 can drive the first gear 61 to rotate, thereby driving the second gear 62 to rotate. The rotation of the second gear 62 can drive the drive pulley 521 to rotate synchronously, so as to drive the scraping member 40 to move through the transmission belt 523 to scrape the filter screen 20.

[0105] The radial dimension of the second gear 62 can be larger than that of the first gear 61. The first gear 61 can rotate synchronously with the drive shaft of the drive motor 51, and the second gear 62 can rotate synchronously with the drive pulley 521. The second gear 62 can mesh with the first gear 61. Thus, based on ensuring that the drive motor 51 and the belt drive mechanism 52 are connected through the gear transmission mechanism 60, the rotational speed of the drive pulley 521 can be reduced, the movement speed of the transmission belt 523 and the scraper 40 can be reduced, the reliability and stability of the movement of the transmission belt 523 and the scraper 40 can be ensured, and the reliability and stability of cleaning the filter screen 20 can be guaranteed. Of course, the drive motor 51 can be connected to the drive pulley 521 so that the drive pulley 521 can rotate synchronously with the output shaft of the drive motor 51. That is, the drive motor 51 can directly drive the drive pulley 521 to rotate, which can ensure the normal movement of the scraper 40 and is conducive to reducing costs.

[0106] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting bracket 10 may include a first bracket 11 and two second brackets 12. The first bracket 11 may have a communication port 111, and the filter screen 20 may be installed at the communication port 111. The two second brackets 12 may be connected to the first bracket 11 in a second direction (e.g., Figure 1 The opposite sides (as shown in the left and right directions) on the left and right sides (e.g.) Figure 1 (as shown on the left and right sides), and the second direction can be the same as the first direction (such as...). Figure 1The vertical orientation (shown in the up-down direction) allows for avoidance of the connecting port 111, facilitating the installation of the scraper 40. This enables the scraper 40 to fit against the filter screen 20 and allows the scraper 40 to move relative to the filter screen 20 in the first direction, ensuring a good cleaning effect on the filter screen 20.

[0107] The two second supports 12 can be identical in structure and arranged opposite each other. The second support 12 can have a sliding groove 121, and the two ends of the scraper 40 (such as...) Figure 8 The left and right ends shown can be respectively provided with sliders 411, so that the two ends of the scraper 40 can slide and cooperate with the sliding grooves 121 of the two second brackets 12 respectively, which can improve the stability of the scraper 40's movement, and make the scraper 40 fit more stably with the filter screen 20 in the first state, which can improve the stability of cleaning the filter screen 20.

[0108] The drive assembly 50 can be mounted on at least one second bracket 12. For example, the drive assembly 50 can be mounted on one second bracket 12, which is beneficial for saving space and reducing costs. Alternatively, the drive assembly 50 can be mounted on two second brackets 12, which is beneficial for the drive assembly 50 to drive the two ends of the scraper 40 to move, and for improving the stability of the scraper 40's movement. It is understood that the drive assembly 50 can be mounted on the side of the two second brackets 12 that is far apart from each other, which can achieve avoidance of the scraper 40, prevent interference between the drive assembly 50 and the scraper 40, improve the reliability of the scraper 40's movement, and at the same time save space.

[0109] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, the belt drive mechanism 52 may include two, and the two belt drive mechanisms 52 may be respectively mounted on two second supports 12. The drive assembly 50 may also include a drive rod 53, with both ends of the drive rod 53 (e.g., Figure 7 The left and right ends shown can be connected to the drive pulleys 521 of the two belt drive mechanisms 52 respectively, so that the two drive pulleys 521 rotate synchronously, and the two ends of the scraping member 40 (such as...) Figure 7 The left and right ends shown can be connected to the transmission belts 523 of the two belt transmission mechanisms 52 respectively, so that the drive motor 51 can be connected to the two ends of the scraper 40 through the two belt transmission mechanisms 52 respectively.

[0110] The drive assembly 50 can drive both ends of the scraper 40 to move synchronously relative to the filter screen 20 along the extension direction of the slide groove 121. This can prevent the scraper 40 from getting stuck due to the different heights at its two ends, and can make the movement of the scraper 40 smoother, thereby improving the reliability of cleaning the filter screen 20. It can be understood that the two belt drive mechanisms 52 can be respectively set on the two second supports 12 on opposite sides, which can avoid the scraper 40, prevent the drive assembly 50 and the scraper 40 from interfering with each other, improve the reliability of the movement of the scraper 40, and at the same time save space.

[0111] In addition, the number of drive motors 51 can be one, and the drive motor 51 can drive the drive pulley 521 of the belt transmission mechanism 52 to rotate, so as to drive the drive pulley 521 of the other belt transmission mechanism 52 to rotate synchronously through the transmission rod 53, which can save costs. Alternatively, the number of drive motors 51 can be two, and the two drive motors 51 can drive the drive pulleys 521 of the two belt transmission mechanisms 52 to rotate respectively, which can improve the power of the drive assembly 50, make the movement of the scraper 40 smoother, and improve the reliability of cleaning the filter screen 20.

[0112] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the scraper 40 may include a mounting portion 41 and a flexible scraper strip 42. The mounting portion 41 may be disposed on the mounting bracket 10, that is, at both ends of the mounting portion 41 (e.g., Figure 8 The left and right ends shown can have sliders 411, so that the end of the mounting part 41 can slide and engage with the slide groove 121 of the mounting bracket 10, and a part of the end of the mounting part 41 can pass through the slide groove 121, and the part of the mounting part 41 that passes through the slide groove 121 can have a limiting groove 412, and one side of the limiting groove 412 (such as...) Figure 11 The front side of the groove wall shown may have mating teeth, and the transmission belt 523 may have second transmission teeth. A part of the transmission belt 523 may extend into the limiting groove 412 so that the second transmission teeth mesh with the mating teeth to realize the connection between the transmission belt 523 and the mounting part 41, thereby allowing the mounting part 41 to move relative to the filter screen 20 along the extension direction of the slide groove 121 to drive the entire scraping part 40 to move normally.

[0113] The flexible scraper 42 can be installed on the side of the mounting part 41 near the filter screen 20 (e.g. Figure 8(as shown on the rear side), and the mounting part 41 can be arranged opposite to the filter screen 20, which is conducive to the flexible scraper 42 adhering to the filter screen 20 to scrape the filter screen 20. The flexible scraper 42 can adhere to the filter screen 20 when the scraper 40 is in the first state, that is, the flexible scraper 42 can adhere to the filter screen 20 when the slider 411 of the mounting part 41 slides and engages with the first groove section 1211 of the slide groove 121. Thus, when the scraper 40 is in the first state, the mounting part 41 can move to drive the flexible scraper 42 to move, so as to scrape off the lint on the filter screen 20, which can improve the cleaning effect on the filter screen 20.

[0114] Understandably, the flexible scraper 42 can be made of flexible materials such as rubber or silicone, allowing it to elastically deform when it adheres to the filter screen 20. This enables a tighter fit between the flexible scraper 42 and the filter screen 20, improving the lint removal effect. Furthermore, the flexible scraper 42 can interfere with the filter screen 20, meaning it can compress the filter screen 20 while adhering to it, causing elastic deformation. For example, a certain amount of interference, such as 1-2 mm, can be maintained between the flexible scraper 42 and the filter screen 20, further enhancing the adhesion and lint removal effect.

[0115] like Figure 8 and Figure 10 As shown, in some embodiments, the flexible scraper 42 may include multiple flexible scraper strips 42, and the multiple flexible scraper strips 42 may extend along the extension direction of the mounting portion 41 (e.g., Figure 8 The left-right spacing arrangement shown in the diagram ensures effective scraping of lint from the filter screen 20, guarantees effective cleaning of the filter screen 20, and reduces the resistance of the scraper 40, allowing for smoother movement and improving the reliability of cleaning the scraper 40. Furthermore, by replacing at least one of the multiple flexible scraper strips 42 with the most severe damage, the entire scraper 40 can be maintained, reducing maintenance costs.

[0116] like Figure 12 , Figure 13 and Figure 14 As shown, according to some embodiments of the present invention, the humidifying assembly 30 may include a water spray pipe 31, which may extend along one side edge of the filter screen 20. The water spray pipe 31 may have a plurality of nozzles 311, such that the plurality of nozzles 311 may be arranged adjacent to the edge of the filter screen 20. The humidifying assembly 30 may spray water onto the filter screen 20 through the plurality of nozzles 311, and the plurality of nozzles 311 may extend along the extending direction of the water spray pipe 31 (e.g., ...). Figure 13 The spacing (as shown in the left-right direction) can increase the humidification range of the filter 20 and improve the uniformity of humidification of the filter 20.

[0117] This ensures that the humidifying component 30 fully humidifies every lint on the filter screen 20, allowing the scraper 40 to more thoroughly scrape off the lint on the filter screen 20, thus improving the cleaning effect on the filter screen 20. The water spray pipe 31 can be equipped with a water inlet valve to control the flow of water into the water spray pipe 31, which is convenient to operate and can prevent water leakage due to damage to the humidifying component 30.

[0118] like Figure 1 and Figure 13 As shown, in some embodiments, the nozzle 311 can be a rectangular opening, so that when the water flow in the spray pipe 31 is sprayed out through the nozzle 311, it can be squeezed by the rectangular opening to form a fan-shaped water curtain, that is, due to the nozzle 311 and one side of the filter screen 20 (e.g. Figure 1 The water in the spray pipe 31 is arranged near the upper edge of the filter screen 20 after being sprayed out through the nozzle 311. Figure 1 The direction shown below) (as shown) Figure 1 It gradually spreads upwards (as shown in the top-to-bottom direction).

[0119] That is, when the water flows through the nozzle 311, the pressure potential energy of the water flow is converted into kinetic energy to generate high-speed jet liquid, and the high-speed jet liquid can generate fan-shaped water curtains under the action of surface tension, so that multiple fan-shaped water curtains can cover the filter screen 20 in the second direction (e.g. Figure 1 The range shown in the left and right directions can increase the humidification range of the filter screen 20, thereby ensuring that the humidification component 30 fully humidifies every piece of lint on the filter screen 20, so that the scraper 40 can more thoroughly scrape off the lint on the filter screen 20, which can improve the cleaning effect of the filter screen 20.

[0120] Among them, the nozzle 311 can be a rectangular opening, and one long side of the rectangular opening is parallel to one side of the filter screen 20 (e.g., Figure 1 The upper edge (as shown) is arranged adjacent to the filter screen 20, and one edge of the long opening can be along one side of the filter screen 20 (e.g., the upper edge). Figure 1 The direction of extension of the upper edge (as shown) Figure 1 The fan-shaped water curtain extends in the left-right direction (as shown), allowing it to extend on the other side near the filter 20 (e.g., ...). Figure 1 The direction shown below) (as shown) Figure 1 As shown in the top-to-bottom direction, upwards towards the opposite sides of the filter 20 (e.g., Figure 1 The diffusion (shown on the left and right sides) can increase the contact area between the water curtain and the filter screen 20, and can increase the humidification range of the filter screen 20, thereby improving the humidification effect of the filter screen 20 and saving water. Alternatively, the nozzle 311 can be a square or round nozzle, which can ensure the humidification effect of the filter screen 20 and facilitate processing.

[0121] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the driving component 50 and the humidifying component 30 may not work simultaneously. That is, the humidifying component 30 may stop working when the scraper 40 is active, and the scraper 40 may stop working when the humidifying component 30 is humidifying the filter screen 20. This can prevent the humidifying component 30 from splashing water outward due to water impacting the scraper 40 when the scraper 40 is scraping the filter screen 20. It also allows the scraper 40 to scrape the filter screen 20 after the lint on the filter screen 20 is humidified, thereby enabling the scraper 40 to scrape off the humidified lint when the humidifying component 30 stops working, which can improve the cleaning effect on the filter screen 20.

[0122] The humidifying component 30 can humidify the filter screen 20 when the scraper 40 is separated from the filter screen 20, that is, the humidifying component 30 can humidify the filter screen 20 when the scraper 40 is in the second state. The scraper 40 can be attached to the filter screen 20 when the humidifying component 30 stops working, that is, the scraper 40 can switch from the second state to the first state when the humidifying component 30 stops working. This helps to prevent the water sprayed by the humidifying component 30 onto the filter screen 20 from directly impacting the scraper 40, and helps the humidifying component 30 spray water or water mist onto the surface of the filter screen 20 to fully humidify the lint, which can ensure the cleaning effect on the filter screen 20. At the same time, it can prevent the water sprayed by the humidifying component 30 from splashing away from the filter screen 20 due to impacting the scraper 40, which can reduce water waste.

[0123] like Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the air duct assembly 1000 according to an embodiment of the present invention includes a base 200 and a filter device 100. The base 200 may have an air duct cavity 201. The filter device 100 may be disposed on the base 200, that is, the mounting bracket 10 of the filter device 100 may be mounted on the base 200. The filter screen 20 may be located at the inlet 2011 of the air duct cavity 201 or inside the air duct cavity 201. The clothes handling device (such as a dryer) can circulate air to the clothes, and the base 200 may be installed inside the clothes handling device so that the circulating air can circulate between the air duct cavity 201 and the clothes, and the filter screen 20 may be located in the airflow path.

[0124] That is, the lint on the clothes can be carried by the airflow through the filter screen 20, thereby filtering the lint and preventing the lint from accumulating in the airflow path. For example, it can prevent the lint from accumulating in the air duct cavity 201, which helps to ensure the circulating air volume in the clothes processing device and the working performance of the clothes processing device. The base 200 can also have a drain cavity 202. The filter device 100 can clean the filter screen 20, and the wastewater (water containing lint) generated by the filter device 100 in cleaning the filter screen 20 can flow to the drain cavity 202 so that the drain cavity 202 can collect and discharge the wastewater.

[0125] According to the embodiment of the present invention, the air duct assembly 1000, by employing the above-mentioned filter device 100, can filter lint and clean the filter screen 20, prevent lint from accumulating in large quantities in the air duct assembly 1000, ensure the ventilation volume of the air duct assembly 1000, prevent lint from causing secondary pollution to clothing, and improve the user experience.

[0126] like Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, according to some embodiments of the present invention, the base 200 may define a cleaning chamber 203, which may be located on one side outside the air duct chamber 201 (e.g. Figure 15 As shown in the front), one side of the cleaning chamber 203 may have an opening, and the cleaning chamber 203 may be connected to the air duct chamber 201 through the inlet 2011 of the air duct chamber 201, which facilitates the installation of the filter assembly and is conducive to the ventilation of the air duct chamber 201. The filter screen 20 may be located at the inlet 2011 of the air duct chamber 201, which can ensure that the lint on the clothes passes through the filter screen 20 with the circulating airflow, which can improve the filtration effect of lint and prevent a large amount of lint from accumulating in the airflow path, and can ensure the ventilation volume of the air duct assembly 1000.

[0127] The base 200 may have a first flow channel 204, which may be located on the other side outside the air duct cavity 201 (e.g., Figure 15As shown on the left), the first flow channel 204 can be set between the drain chamber 202 and the cleaning chamber 203, and the first flow channel 204 can be connected to the drain chamber 202 and the cleaning chamber 203 respectively. The wastewater (water with lint) generated by the cleaning filter screen 20 of the filter device 100 can flow to the bottom of the cleaning chamber 203. The first flow channel 204 can guide the wastewater in the cleaning chamber 203 to the drain chamber 202 so that the drain chamber 202 can collect and discharge the wastewater. At the same time, by setting the first flow channel 204 on the outside of the air duct chamber 201, the first flow channel 204, the second flow channel 205 and the air duct chamber 201 can be independent of each other, and the first flow channel 204 can discharge lint on its own. This can prevent the wastewater in the first flow channel 204 from flowing into the mounting chamber and contaminating the entire base 200, and can improve the cleaning effect of lint.

[0128] like Figure 15 , Figure 18 and Figure 19 As shown, in some embodiments, at least a portion of the bottom wall of the first flow channel 204 may be in the direction from the cleaning chamber 203 to the drain chamber 202 (e.g., Figure 19 As shown in the direction from front to back, gradually downwards (e.g.) Figure 19 The inclined extension (as shown in the top-to-bottom direction) can improve the guiding effect on the flow of wastewater, so that the wastewater in the cleaning chamber 203 can flow more smoothly through the first flow channel 204 to the drain chamber 202, so that the drain chamber 202 can collect and discharge the wastewater.

[0129] like Figure 18 and Figure 19 As shown, in some embodiments, the bottom wall of the cleaning chamber 203 may be provided with a first guide groove 2031, which may communicate with the first flow channel 204. The bottom wall of the first guide groove 2031 may be arranged along a direction close to the first flow channel 204 (e.g., Figure 18 As shown, the direction from right to left gradually downwards (e.g.) Figure 19 As shown in the top-to-bottom direction, it extends obliquely, and the side of the first guide channel 2031 closest to the first flow (such as...) Figure 18 The left side shown may have a first flow guide port, and the first flow guide groove 2031 is connected to the first flow channel 204 through the first flow guide port.

[0130] On the one hand, it can improve the guiding effect of wastewater flow, so that the wastewater in the cleaning chamber 203 can flow more smoothly into the first flow channel 204 through the first guide channel 2031. On the other hand, it can reduce the connection area between the cleaning chamber 203 and the first flow channel 204, which can prevent the wastewater in the first flow channel 204 from flowing back into the cleaning chamber 203 and contaminating the entire base 200, and can improve the cleaning effect of lint.

[0131] like Figure 16 and Figure 17 As shown, according to some embodiments of the present invention, a heat exchanger 300 may be provided inside the air duct cavity 201, and the heat exchanger 300 may be positioned in the airflow direction (e.g., Figure 16 As shown in the front-to-back direction, it is located downstream of the filter 20, so that the circulating air can enter the air duct cavity 201 and flow through the heat exchanger 300 after passing through the filter 20. This can prevent a large amount of lint from accumulating in the air duct cavity 201 and on the heat exchanger 300, ensure the ventilation of the air duct cavity 201, and ensure the contact effect between the heat exchanger 300 and the circulating air, thereby ensuring the heat exchange effect of the circulating air and ensuring the working performance of the clothing processing device.

[0132] like Figure 16 , Figure 17 , Figure 20 and Figure 21 As shown, in some embodiments, the heat exchanger 300 may contain a cooling medium, and the heat exchanger 300 may include an evaporator 301 and a condenser 302. The cooling medium may circulate through the evaporator 301 and the condenser 302, and in the airflow direction (e.g., ... Figure 17 As shown in the front-to-back direction, the evaporator 301 can be located between the condenser 302 and the filter screen 20, that is, after being filtered by the filter screen 20, the circulating air can flow through the evaporator 301 and the condenser 302 in sequence to achieve heat exchange of the circulating air.

[0133] For example, after the circulating air flows through the damp and hot clothes, it will carry the high-temperature water vapor from the damp and hot clothes. The circulating air can flow through the inlet 2011 of the air duct cavity 201, through the filter screen 20, and then through the evaporator 301. The cooling medium in the evaporator 301 can absorb heat to cool the circulating air to form a low-temperature circulating air, so that the high-temperature water vapor in the circulating air forms condensate on the surface of the evaporator 301 to remove the high-temperature water vapor from the damp and hot clothes in the circulating air.

[0134] The cooled low-temperature circulating air can continue to flow through the condenser 302, and the cooling medium that has absorbed heat flows to the condenser 302 to release heat to heat the circulating air to form dry high-temperature circulating air. The dry high-temperature circulating air can flow through the outlet 2012 of the air duct cavity 201 again through the humid and hot clothes to continue to absorb high-temperature water vapor. The above-mentioned circulating air can circulate between the air duct cavity 201 and the clothes.

[0135] This allows for the drying of clothes and the reuse of heat from damp clothes, reducing energy consumption. Of course, the air duct assembly 1000 or the clothes handling device can be equipped with a heating element in the airflow path. The heating element can be located downstream of the filter 20 in the airflow direction to heat the circulating air, which can improve the heating effect of the circulating air. This allows the circulating air to absorb more high-temperature water vapor when it flows through damp clothes, thus improving the drying effect of the clothes.

[0136] Among them, the bottom wall of the air duct cavity 201 is below (e.g. Figure 17 The evaporator 301 (shown below) may have a second flow channel 205, which may be located between the air duct cavity 201 and the drain cavity 202. The second flow channel 205 may be connected to the air duct cavity 201 and the drain cavity 202 respectively. The condensate generated on the surface of the evaporator 301 may flow to the bottom of the air duct cavity 201. The second flow channel 205 may guide the condensate in the air duct cavity 201 to the drain cavity 202 so that the drain cavity 202 can collect and discharge the condensate.

[0137] like Figure 17 and Figure 21 As shown, in some embodiments, at least a portion of the bottom wall of the second flow channel 205 may be along a direction close to the drain cavity 202 (e.g., Figure 17 As shown, the direction from front to back gradually decreases (e.g.) Figure 17 The inclined extension (as shown in the top-to-bottom direction) can improve the guiding effect on the flow of condensate, so that the condensate in the air duct cavity 201 can flow more smoothly through the second flow channel 205 to the drain cavity 202, so that the drain cavity 202 can collect and discharge the condensate.

[0138] like Figure 16 , Figure 17 , Figure 20 and Figure 21 As shown, in some embodiments, the bottom wall of the air duct cavity 201 may be provided with a second guide groove 2013, which may communicate with the second flow channel 205. The bottom wall of the second guide groove 2013 may be arranged along a direction close to the second flow channel 205 (e.g., Figure 16 As shown, the direction from right to left gradually downwards (e.g.) Figure 17 As shown in the top-to-bottom direction, it extends obliquely, and the side of the second guide channel 2013 closest to the second flow (as shown in the top-to-bottom direction) is inclined. Figure 16 The left side shown may have a second guide port, and the second guide channel 2013 is connected to the second flow channel 205 through the second guide port. The second guide channel 2013 may correspond to the position of the evaporator 301, so that the condensate generated on the surface of the evaporator 301 can flow directly to the second guide channel 2013.

[0139] On the one hand, it can improve the guiding effect on the flow of condensate, so that the condensate in the air duct cavity 201 can flow more smoothly into the second flow channel 205 through the second guide groove 2013. On the other hand, it can reduce the connection area between the air duct cavity 201 and the second flow channel 205, which can prevent the condensate in the second flow channel 205 from flowing back into the installation cavity and affecting the heat exchange effect of the heat exchanger 300 on the circulating air, and can also prevent the circulating air from entering the second flow channel 205, thus improving the stability of condensate drainage.

[0140] like Figure 15 , Figure 16 , Figure 18 and Figure 19 As shown, according to some embodiments of the present invention, the air duct assembly 1000 may further include at least one water pump 400, which may be disposed in the drain chamber 202. The water pump 400 may drive the water in the drain chamber 202 to flow outward, so as to discharge the water mixed with lint in the drain chamber 202, thereby realizing automatic cleaning of lint.

[0141] Among them, the end of the first flow channel 204 (such as Figure 19 The rear end shown) and the end of the second flow channel 205 (as shown) Figure 17 The rear end shown can be connected to the drain chamber 202, so that the drain chamber 202 can collect condensate and wastewater and discharge them together. There can be one water pump 400. A single water pump 400 can be set in the drain chamber 202 to discharge the water in the drain chamber 202. Of course, there can be multiple water pumps 400. Multiple water pumps 400 cooperate to make it easier to discharge the water in the drain chamber 202, and can prevent the water from being difficult to discharge due to the presence of a large amount of lint.

[0142] In some embodiments, the water pump 400 may have multiple cutting elements that can rotate synchronously with the blades of the water pump 400. This allows for the cutting of lint in the water, preventing lint from clogging the water pump 400 and improving the reliability and stability of drainage from the drainage chamber 202. The cutting elements can be blades mounted on the blades or blades mounted on the output shaft of the water pump 400, allowing the blades to rotate coaxially with the blades. This improves the cutting effect on lint and the cleaning effect on lint.

[0143] According to an embodiment of the present invention, a clothing processing device includes a filter device 100 or an air duct assembly 1000. By employing the filter device 100 or the air duct assembly 1000, lint can be filtered, the filter screen 20 can be cleaned, a large amount of lint can be prevented from accumulating in the airflow path, the circulating air volume in the clothing processing device can be guaranteed, the working performance of the clothing processing device can be guaranteed, secondary pollution of clothing by lint can be prevented, the processing effect on clothing can be improved, and the user experience can be enhanced.

[0144] The following reference Figures 1-21To describe a specific embodiment of this application, the clothing processing device can be a dryer. The clothing processing device can include an air duct assembly 1000. The air duct assembly 1000 can include a base 200, a heat exchanger 300, and a filter device 100. The base 200 can define an air duct cavity 201, a drain cavity 202, and a cleaning cavity 203. The heat exchanger 300 can be installed in the air duct cavity 201. The air duct cavity 201 can communicate with the drain cavity 202. The filter device 100 can be installed in the cleaning cavity 203. The cleaning cavity 203 can communicate with the drain cavity 202. A water pump 400 can be installed in the drain cavity 202.

[0145] The filtration device 100 may include a mounting bracket 10, a filter screen 20, a humidification assembly 30, a scraper 40, and a drive assembly 50. The filter screen 20 may be mounted on the mounting bracket 10, which may have a groove 121. The end of the scraper 40 may have a slider 411, which may slide in cooperation with the groove 121. The groove 121 may include a second groove segment 1212 and a first direction (e.g., along a second groove segment 1212). Figure 2 The first groove segment 1211 extends in the vertical direction (as shown), and the second groove segment 1212 can connect with one end of the first groove segment 1211 (e.g., in the vertical direction). Figure 2 The upper end shown is connected, and the second groove segment 1212 can be connected in a direction away from the first groove segment 1211 (e.g., the upper end shown is connected), and the second groove segment 1212 can be connected in a direction away from the first groove segment 1211 (e.g., the upper end shown is connected). Figure 2 As shown in the direction from bottom to top, it gradually moves away from the filter 20 (e.g., Figure 2 (As shown, it extends obliquely from front to back).

[0146] The scraper 40 can have a first state and a second state. When the scraper 40 is in the first state, its slider 411 can slide and engage with the first groove segment 1211 to make the scraper 40 fit against the filter screen 20. When the scraper 40 is in the second state, its slider 411 can slide and engage with the second groove segment 1212 to separate the scraper 40 from the filter screen 20. The drive assembly 50 can drive the scraper 40 to move relative to the filter screen 20 along the extension direction of the groove 121, allowing the scraper 40 to freely switch between the first and second states. The humidification assembly 30 is disposed on one side of the filter screen 20 (e.g., ...). Figure 5 The humidification assembly 30 is located on the upper edge of the slide groove 121 and between the filter screen 20. When the wiping member is in the second state, the humidification assembly 30 can spray water onto the filter screen 20 to humidify the lint on the surface of the filter screen 20.

[0147] The clothing treatment device can introduce circulating air into the damp clothes. The circulating air can circulate between the damp clothes and the air duct cavity 201. After flowing through the damp clothes, the circulating air will carry the high-temperature water vapor from the damp clothes. The circulating air carrying the high-temperature water vapor can first enter the air duct cavity 201 through the filter screen 20, which can filter out the lint on the clothes. The circulating air can also flow through the heat exchange element 300 in the air duct cavity 201 to form dry high-temperature circulating air. The high-temperature water vapor in the circulating air is cooled to form condensate. The dry high-temperature circulating air can flow through the damp clothes again to continue to absorb high-temperature water vapor, which can dry the clothes. At the same time, the condensate in the air duct cavity 201 can flow into the drain cavity 202.

[0148] After the garment processing device processes garments multiple times or for an extended period of time, a large amount of lint will accumulate on the surface of the filter screen 20. At this time, the scraper 40 is in the second state, and the humidifying component 30 can spray water onto the filter screen 20 to moisten the lint. When the humidifying component 30 stops working, the driving component 50 can drive the scraper 40 to move and switch from the second state to the first state, so that the scraper 40 scrapes off the lint on the filter screen 20. The driving component 50 can also drive the scraper 40 to continue moving and switch from the first state to the second state, so that the humidifying component 30 can spray water onto the filter screen 20 again to perform a secondary cleaning of the filter screen 20. At the same time, wastewater (water containing lint) can flow into the drain chamber 202, and the water pump 400 can drive the water in the drain chamber 202 to flow outward to discharge the water.
