[0045] According to an embodiment of the present application, a filter device 100 is provided, as shown in Figure 1 , Figure 2 and Figure 3 , the filter device 100 comprises a filter screen assembly 10 and a handle assembly 20.

[0046] The filter screen assembly 10 is used to be installed in the circulating air duct 220, so as to filter the air flow in the circulating air duct 220. Specifically, the filter screen assembly 10 comprises a filter screen support 11 and a first filter screen 12. The filter screen support 11 serves as a support structure of the filter screen assembly 10, and functions to carry and fix the first filter screen 12. The filter screen support 11 should be adapted to the installation space of the circulating air duct 220 in shape and size, and can be designed according to the shape of the specific drying machine circulating air duct 220, for example, can be rectangular, circular, etc. In addition, the filter screen support 11 should have certain strength and stability to ensure normal operation in the air duct and withstand the force when cooperating with the handle assembly 20 subsequently. The first filter screen 12 is covered on the filter screen support 11. The material of the first filter screen 12 can be selected from materials with fine and certain air permeability, for example, stainless steel wire woven mesh or high-temperature-resistant fiber filter screen, etc. The mesh size is designed according to the size of the lint, fiber and other debris to be intercepted, which can effectively block these impurities from passing through, while allowing normal air circulation, ensuring smooth air circulation in the air duct to achieve normal drying of clothes.

[0047] The handle assembly 20 comprises a handle support 21 and a lint brush 22. The handle support 21 is the main frame part of the whole handle assembly 20, and is shaped to facilitate the operation of a human hand. The handle support 21 is slidably connected to the filter screen support 11 along the first direction X. The material of the handle support 21 can be plastic or light metal with certain strength and toughness, which is convenient for the user to pull and is not easy to be damaged.

[0048] In detail, the handle support 21 of the handle assembly 20 is connected to the filter screen support 11 of the filter screen assembly 10 by sliding connection, and the relative sliding direction of the two is the first direction X, which is parallel to the screen surface of the first filter screen 12. In some embodiments, the sliding connection can be realized by the cooperation of a guide rail and a sliding block. For example, a guide rail is arranged on the filter screen support 11, and a sliding block is arranged on the handle support 21 in a corresponding manner, so that the handle support 21 can stably reciprocate along the guide rail relative to the filter screen support 11. In other embodiments, the handle support 21 and the filter screen support 11 are connected in the form of a clamping groove and a protrusion. A clamping groove is arranged on the filter screen support 11, and a protrusion matching the clamping groove is arranged on the handle support 21, so that the handle support 21 can slide along the direction defined by the clamping groove, thereby ensuring reliable connection and smooth sliding.

[0049] In the normal operation of the clothes treatment device 200 (for example, a clothes dryer), air containing lint, fibers and other lint flows in the circulating air duct 220. When passing through the filter screen assembly 10, the air can continue to circulate through the first filter screen 12, while the lint is intercepted by the first filter screen 12 and adheres to the screen surface. When it is necessary to remove the lint accumulated on the first filter screen 12, the user holds the handle support 21 and pulls the handle support 21 away from the filter screen support 11 along the first direction X parallel to the screen surface of the first filter screen 12. During the pulling process, the lint brush 22 installed on the handle support 21 moves synchronously with the handle support 21. Since the lint brush 22 abuts against the screen surface of the first filter screen 12, the lint brush 22 slides along the screen surface of the first filter screen 12, and the lint accumulated on the first filter screen 12 is scraped off by the scraping action of the bristles, so as to separate the lint from the first filter screen 12 and achieve the purpose of cleaning the lint. After cleaning, the handle support 21 can be pushed in the opposite direction to reset to the initial position, so as to facilitate the next lint cleaning operation.

[0050] According to the filter device 100, the lint on the filter screen can be scraped and cleaned by the lint brush 22 through simply pulling the handle support 21, the cleaning process is greatly simplified, the time and effort of the user are saved, and the convenience of use is improved.

[0051] It should be noted that the conventional cleaning method may cause damage to the filter screen due to frequent disassembly and installation of the filter screen assembly 10, and the device does not need to disassemble the filter screen assembly 10, reduces unnecessary external damage to the first filter screen 12, and keeps the surface of the first filter screen 12 relatively clean and tidy, which is beneficial to the long-term stable filtering effect of the first filter screen 12, prolongs the overall service life, and reduces the use cost.

[0052] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 8 , the first filter screen 12 is annularly arranged around the circumferential edge of the filter screen support 11, that is, the first filter screen 12 is in a cylindrical structure, and the cylindrical structure of the first filter screen 12 allows the first filter screen 12 to enclose the filtering cavity 101, and the surface of the first filter screen 12 defines an air inlet 1011 connected with the filtering cavity 101, that is, the airflow passes through the first filter screen 12 from the outer circumferential surface of the first filter screen 12 into the filtering cavity 101, so that the lint, fibers and other impurities mixed in the airflow are blocked on the outer circumferential surface of the first filter screen 12, and the clean airflow is formed after the air flow is filtered by the first filter screen 12 and enters the filtering cavity 101, and at least one end of the filtering cavity 101 along the first direction X forms an air outlet 1012, and the air is filtered by the first filter screen 12 and flows out from the air outlet 1012, completing the filtering cycle.

[0053] The filter screen support 11 is located inside the first filter screen 12 and serves to support the first filter screen 12. The shape of the filter screen support 11 is adapted to the first filter screen 12, so that the first filter screen 12 can be stably arranged around the circumferential edge thereof. The filter screen support 11 provides structural stability for the entire filter screen assembly 10, and ensures that the first filter screen 12 will not be deformed due to air pressure or other external forces during operation, thereby ensuring the normal form and filtering function of the filtering cavity 101.

[0054] The handle bracket 21 includes a handle body 211 and a support portion 212. The handle body 211 is for the user to grip, facilitating operation of the handle assembly 20. The support portion 212 is connected to the handle body 211 and surrounds the outside of the first filter screen 12 circumferentially. The support portion 212 serves as the mounting base for the lint brush 22. The shape and size of the support portion 212 match the outer periphery of the first filter screen 12, ensuring that the lint brush 22 can tightly surround the first filter screen 12 and make full contact with the mesh surface of the first filter screen 12, thereby effectively scraping off lint. The lint brush 22 is mounted on the support portion 212 and is arranged circumferentially around the first filter screen 12. The bristles have moderate length and hardness, allowing them to penetrate deep into the mesh openings when in contact with the first filter screen 12, effectively scraping off lint adhering to the mesh without damaging the filter screen. The bristles of the lint brush 22 are closely arranged and surround the filter screen 12, ensuring that the first filter screen 12 can be cleaned in the entire circumferential direction.

[0055] In this embodiment, please refer to Figure 3 and Figure 12 As shown, when the garment processing device 200 is working, air containing lint enters through the air inlet 1011 of the filter chamber 101 enclosed by the first filter 12. As the air passes through the first filter 12, lint is trapped on its outer surface, and the filtered air flows out through the air outlet 1012 of the filter chamber 101. When lint needs to be cleaned, the user holds the handle body 211 and pulls the handle bracket 21 away from the filter bracket 11 along the first direction X, causing the lint brush 22 mounted on the handle assembly 20 support 212 to slide along with the handle assembly 20. Because the lint brush 22 is circumferentially arranged around the first filter 12 and in close contact with the mesh surface of the first filter 12, the lint brush 22 slides circumferentially on the outer surface of the first filter 12, with the bristles penetrating between the mesh openings to scrape off the lint adhering to the first filter 12, thereby cleaning the first filter 12 and ensuring the continued effectiveness of its filtering function. After cleaning, push the handle assembly 20 back in the opposite direction, and the lint brush 22 will once again adhere to the first filter screen 12, ready for the next cleaning.

[0056] In the embodiment, the first filter screen 12 is arranged in a ring shape to make full use of the space, increase the filtering area, and improve the filtering efficiency of the lint. Moreover, the lint brush 22 is arranged around the first filter screen 12, so that the filter screen in the entire circumferential direction can be cleaned at one time during cleaning, ensuring that each part of the first filter screen 12 can be effectively cleaned and avoiding the problem of incomplete cleaning in some parts, thereby further improving the cleaning efficiency. Moreover, the support part 212 and the lint brush 22 are arranged in a ring shape around the first filter screen 12, so that the entire filtering device 100 has good structural stability, and the relative position between the handle assembly 20 and the filter screen assembly 10 can be kept stable when the filtering device 100 bears the pulling force during the cleaning process, thereby reducing the problems of deformation and loosening of the first filter screen 12 and ensuring the normal operation of the filtering function and the cleaning function of the filtering device 100.

[0057] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 8 , the filter screen support 11 includes a first support 111 and a second support 112, the first support 111 and the second support 112 are arranged at intervals along the first direction X, and the inner wall surface of the first filter screen 12 is connected to the circumferential edge of the first support 111 and the second support 112, respectively, to form a structure similar to a cylinder. The first support 111 and the second support 112 are arranged at intervals to enable the first filter screen 12 to form a filtering cavity 101 between the first support 111 and the second support 112 for the circulation and filtering of air. The first support 111 and the second support 112 provide support for the first filter screen 12. The first support 111 is in a plate shape and is provided with a first cleaning port 1111, the second support 112 is in a hollow frame structure, and the first filter screen 12 defines an air outlet 1012 at one end of the second support 112. The filter screen assembly 10 further includes a first plate body 13, which is detachably mounted to the first support 111. The shape of the first plate body 13 is adapted to the first support 111, and the first plate body 13 seals the first cleaning port 1111. The material of the first plate body 13 includes but is not limited to one of plastic or metal. The first plate body 13 has a certain strength and sealing property, which can effectively prevent air from leaking from the first cleaning port 1111 and ensure that air is filtered through the first filter screen 12 according to the designed path.

[0058] The inner wall surface of the first filter screen 12 is tightly connected to the circumferential edges of the first support 111 and the second support 112. The first filter screen 12 can be connected to the first support 111 and the second support 112 by welding, buckling connection or glue sticking, etc., to ensure the fixation of the first filter screen 12 between the two supports. The first plate body 13 and the first support 111 are in a detachable connection relationship, for example, the first plate body 13 is connected to the first support 111 by a clamping groove-clamping block mode, the clamping block is arranged on the edge of the first plate body 13, and the corresponding clamping groove is arranged on the first support 111, so that the clamping block is inserted into the clamping groove to complete the installation, and the reverse operation can be performed to disassemble; or the first plate body 13 and the first support 111 are connected by a screw, and the corresponding screw holes are arranged on the first plate body 13 and the first support 111, and the screw is used for fixation and disassembly.

[0059] In this embodiment, when the clothes dryer is running, air carrying impurities such as lint flows from the outside to the inside of the first filter screen 12. Due to the filtering effect of the first filter screen 12, the lint is intercepted on the outside of the filter screen, and the air enters the filtering cavity 101 formed by the first filter screen 12 and the two supports through the first filter screen 12, and the filtered air is discharged from the air outlet 1012 at one end of the second support 112 into the subsequent air duct or circulation system, thereby realizing the filtration of the air and ensuring that the air entering the next link is relatively clean, avoiding the adverse effects of lint on other parts of the clothes dryer or the dried clothes.

[0060] It should be noted that the first cleaning port 1111 and the detachable first plate body 13 provide convenience for cleaning the inside of the first filter screen 12. After long-term use, even if the outside of the filter screen is cleaned by the lint brush 22, etc., some impurities may still accumulate inside the first filter screen 12. When the inside of the first filter screen 12 needs to be cleaned, the first plate body 13 can be detached from the first support 111, and at this time the first cleaning port 1111 is opened. The inside of the first filter screen 12 and the filtering cavity 101 between the two supports can be cleaned by using a tool (such as a brush, a vacuum cleaner, etc.) through the first cleaning port 1111, to ensure the cleanliness of the entire first filter screen 12 and prolong the service life of the first filter screen 12. After cleaning, the first plate body 13 is installed back to the first support 111 to block the first cleaning port 1111, so that the filtering device 100 returns to the normal working state.

[0061] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 8As shown, the filter screen support 11 further comprises a plurality of connecting rods 113 extending along the first direction X, each of the connecting rods 113 is in the shape of a long strip, and both ends of each of the connecting rods 113 are connected to the first support 111 and the second support respectively. The plurality of connecting rods 113 are arranged in sequence along the circumference of the first filter screen 12 and are connected to the inner wall surface of the first filter screen 12, so as to support the inside of the first filter screen 12 by means of the plurality of connecting rods 113, and prevent the first filter screen 12 from being deformed by being concave inwardly during the operation.

[0062] In the embodiment, the first support 111 and the second support 112 are connected by the connecting rods 113, and both ends of each of the connecting rods 113 are firmly connected to the first support 111 and the second support 112 respectively, forming a stable frame structure. Meanwhile, the inner wall surface of the first filter screen 12 is closely connected to the connecting rods 113, the first support 111 and the second support 112, and the connection mode can be welding or pasting by using special glue, etc. For example, high-temperature-resistant glue can be used at the connecting part 2112, so as to make the inner wall surface of the first filter screen 12 closely adhere to the connecting rods 113, the first support 111 and the second support 112, and ensure that no loosening phenomenon occurs during the operation.

[0063] In other embodiments, as shown in Figure 6 and Figure 7 , the filter screen support 11 can also not be provided with the first support 111 and the connecting rods 113, and both ends of the first filter screen 12 along the first direction X are connected to the first plate body 13 and the second support 112 respectively.

[0064] In some embodiments, as shown in Figure 3 , Figure 6 and Figure 8 , the filter screen assembly 10 further comprises a second filter screen 14, which is connected to the first support and covers the air outlet 1012. The material and mesh size of the second filter screen 14 are determined according to the size of the impurity particles to be further filtered, and the mesh of the second filter screen 14 is finer than that of the first filter screen 12, so as to intercept the fine impurities that can pass through the first filter screen 12. The shape is adapted to the air outlet 1012, so as to ensure that the air outlet 1012 is completely covered and the unfiltered impurities are prevented from passing through. In the embodiment, the second filter screen 14 is provided in the form of a sponge structure with multiple pores, and the sponge structure has abundant pores providing a large surface area. When air passes through the second filter screen 14, tiny impurities such as fine fibers and dust particles can be adsorbed on the surface of the pores of the sponge. Compared with the traditional filter screen, the adsorption of the sponge is more effective for capturing tiny impurities, which can greatly improve the filtering precision and ensure that the filtered air is purer, reducing the possibility of impurities entering the inside of the clothes dryer.

[0065] In the embodiment, please refer to Figure 3 andFigure 12 As shown, when the laundry treating apparatus 200 is in operation, the air with lint and other impurities first contacts the first filter screen 12. The air flows from the outside to the inside of the first filter screen 12, and the first filter screen 12 intercepts most of the larger lint, and the filtered air enters the filtering cavity 101 surrounded by the first filter screen 12 and the filter screen support 11. Then, the air flows to the air outlet 1012 at one end of the second support 112, and the second filter screen 14 performs secondary filtering on the air when passing through the air outlet 1012. The second filter screen 14 is used to intercept fine impurities that can pass through the first filter screen 12, such as smaller fiber particles, and the air after secondary filtering enters the downstream side of the circulating air duct 220 and exchanges heat with the evaporator and the condenser one by one.

[0066] In some embodiments, please refer to Figure 3 and Figure 9 As shown, the handle body 211 includes a second plate body 2111 and a connecting portion 2112, the connecting portion 2112 is connected to the second plate body 2111 and the support portion 212 at both ends along the first direction X, so that a stable overall structure is formed between the support portion 212 and the second plate body 2111. The second plate body 2111 is arranged opposite and spaced apart from the first plate body 13 along the first direction X, the first plate body 13 is provided with a fitting groove 131 recessed toward the inside of the filtering cavity 101 along the first direction X, and the second plate body 2111 is provided with a boss portion 21111 protruding toward the fitting groove 131 along the first direction X, and the boss portion 21111 is detachably inserted into the fitting groove 131 along the first direction X. In the normal working state, the boss portion 21111 of the second plate body 2111 is inserted into the fitting groove 131 of the first plate body 13, so that the handle assembly 20 and the first plate body 13 are tightly connected together. When the user needs to clean the first filter screen 12, the boss portion 21111 can be pulled out of the fitting groove 131 by holding the handle body 211 and applying a certain pulling force, so that the handle assembly 20 is separated from the filter screen assembly 10 and is detached, and in this process, the lint brush 22 scrapes and cleans the accumulated lint and other deposits on the outer circumferential surface of the first filter screen 12. After cleaning, the boss portion 21111 is reinserted into the fitting groove 131 to restore to the normal working state. In detail, when cleaning the lint on the first filter screen 12, the user can hold the handle body 211 and pull the handle support 21 along the first direction X, so that the lint brush 22 cleans the first filter screen 12, and at this time, the connecting portion 2112 ensures the linkage of the handle body 211 and the support portion 212, so that the lint brush 22 can work effectively.

[0067] Further, as shown in Figure 3As shown, the boss portion 21111 is provided with a chamfer structure 21112 at the circumferential edge of the one end of the first plate body 13, and the outer diameter size of the chamfer structure 21112 gradually decreases along the first direction X and from the direction of the second plate body 2111 to the first plate body 13. The chamfer structure 21112 of the boss portion 21111 plays a guiding role in the connection process, facilitating the insertion of the boss portion 21111 into the assembly groove 131. When installing, due to the gradually decreasing outer diameter of the chamfer structure 21112, when the boss portion 21111 approaches the assembly groove 131, even if there is a certain positional deviation, the chamfer structure 21112 can guide the boss portion 21111 to be smoothly inserted into the assembly groove 131.

[0068] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 9 , along the first direction X, the second plate body 2111 is provided with a gripping portion 2113 on the side surface away from the first plate body 13, and the gripping portion 2113 protrudes towards the direction away from the first plate body 13. In detail, the gripping portion 2113 is provided on the side surface of the second plate body 2111 away from the first plate body 13, and the gripping portion 2113 protrudes outward (in the direction away from the first plate body 13) relative to the second plate body 2111. The shape of the gripping portion 2113 can be various ergonomic designs, such as a long strip-shaped protrusion that is convenient for the fingers to hold, or a block-shaped protrusion with an arc that matches the shape of the palm to provide a more comfortable holding experience. The surface of the gripping portion 2113 can be provided with anti-slip texture or coated with anti-slip material to increase friction and prevent the hand from slipping during holding.

[0069] When the user needs to operate the handle body 211, for example, in the process of cleaning the lint on the first filter screen 12 (pulling the handle bracket 21 along the first direction X), the fingers can hold the gripping portion 2113, and when the user applies force to operate, the force can be effectively transmitted to the handle body 211 through the gripping portion 2113, smoothly driving the lint brush 22 to clean the first filter screen 12.

[0070] Further, as shown in Figure 3As shown, the gripping portion 2113 includes a connecting plate 21131 and a gripping plate 21132, one end of the connecting plate 21131 is connected with the second plate body 2111, and the connecting plate 21131 serves to connect the gripping plate 21132 and the second plate body 2111. The connecting plate 21131 can be in the shape of a flat plate, and the length and width thereof can be determined according to the overall design and actual requirements. One end of the connecting plate 21131, which is away from the second plate body 2111, is connected with the gripping plate 21132, and the connecting plate 21131 is perpendicular to the gripping plate 21132. The gripping plate 21132 is a part directly for a user to grip. The gripping plate 21132 is in the shape of a plate and is parallel to the second plate body 2111. The boss portion 21111 is formed with a gripping groove 21113 on the side of the second plate body 2111 away from the first plate body 13. The gripping plate 21132 is opposite to and spaced apart from the gripping groove 21113 along the first direction X, so as to form a space for accommodating fingers of an operator between the gripping plate 21132 and the gripping groove 21113, thereby facilitating the user to grip.

[0071] When the user needs to operate the handle, the fingers hold the gripping plate 21132. Since the gripping plate 21132 is at an angle with the connecting plate 21131, the fingers can be naturally bent and attached to the gripping plate 21132. At the same time, the other side of the fingers will extend into the gripping groove 21113. When the user applies force to operate (such as pulling the handle bracket 21), the gripping plate 21132 transmits the force to the connecting plate 21131, and then transmits the force to the second plate body 2111 through the connecting plate 21131, thereby driving the entire handle assembly 20 to perform corresponding actions.

[0072] In some embodiments, as shown in FIG. 6, Figure 9 As shown, the connecting portion 2112 includes a receiving plate extending along the circumferential direction of the supporting portion 212. The shape of the receiving plate is a ring or an approximately ring structure matching the outer circumferential shape of the supporting portion 212. This ring design enables the receiving plate to receive the accumulation of hair scraps in the circumferential direction. The receiving plate, the second plate body 2111 and the supporting portion 212 together enclose a receiving space for accommodating the accumulation of hair scraps. The receiving plate is provided with at least one second cleaning port 21121 communicating with the receiving space. The size and shape of the second cleaning port 21121 can be designed according to actual requirements, for example, it can be circular, square or long and narrow slit shape. The main function of the second cleaning port 21121 is to provide a channel for cleaning and dumping the hair scraps accumulated in the receiving space.

[0073] In the embodiment, when the first filter screen 12 is cleaned by the handle assembly 20, the lint brush 22 slides along the first filter screen 12, and the scraped lint deposits fall off. Since the second plate body 2111, the receiving plate and the support part 212 jointly enclose the containing space, the falling lint is collected in the space. As the cleaning work proceeds, the lint is continuously accumulated in the containing space. When the lint needs to be cleaned, the second cleaning port 21121 on the receiving plate can be used to clean the lint. For example, a small cleaning tool (such as a brush, a small vacuum cleaner, etc.) can be used to clean the lint out of the containing space through the second cleaning port 21121, or the lint can be poured out through the second cleaning port 21121, so that the containing space maintains a certain containing capacity for the next time the first filter screen 12 is cleaned.

[0074] According to the embodiments of the present application, as shown in Figure 10 , a laundry treatment device 200 is also provided, which includes but is not limited to a clothes dryer, a dry cleaning integrated machine, etc. The present application takes the clothes dryer as an example for illustration.

[0075] Specifically, as shown in Figure 3 , Figure 10 , Figure 11 and Figure 12 , the laundry treatment device 200 includes a cabinet 210 and a filter device 100. The inside of the cabinet 210 defines a circulating air duct 220, and the filter screen assembly 10 in the filter device 100 is installed in the circulating air duct 220. During the treatment process of the laundry, the lint such as the fluff and the fiber on the laundry is easily circulated in the circulating air duct 220 along with the airflow. The filter screen assembly 10 of the filter device 100 is installed in the circulating air duct 220, which can effectively intercept the lint and avoid the lint from being attached to the laundry being treated again. For example, after the blanket is dried, a large amount of fluff that falls off the blanket is intercepted by the filter screen assembly 10, so that the surface of the dried blanket is cleaner and neater, the overall treatment effect of the laundry is improved, and the user has a better use experience.

[0076] Further, the cabinet 210 comprises a base 2101 and a box 2102 arranged on the base 2101, and the circulating air duct 220 comprises a main air duct 2201, branch air ducts and a drying cavity, the main air duct 2201, the branch air ducts and the drying cavity are sequentially connected in a head-to-tail manner to form a circulating passage for air flow, and the drying cavity is a space for placing clothes to be treated, and the branch air ducts are used to connect the main air duct 2201 and the drying cavity, so that air can uniformly enter the drying cavity and take away moisture or other impurities in the clothes. Specifically, the base 2101 defines the main air duct 2201, the box 2102 defines the drying cavity and the branch air ducts, the main air duct 2201 is provided with an evaporator and a condenser, and the filter screen assembly 10 is installed in the main air duct 2201 and located at the air inlet 1011 of the main air duct 2201, and the filter screen assembly 10 is located on the upstream side of the evaporator and the condenser.

[0077] When the clothes treatment device 200 starts to work, the air flow is driven to circulate by the impeller arranged in the branch air duct, and after the hot air completes the dehumidification of the clothes in the drying cavity, the air flow carrying lint and water vapor is discharged from the air outlet 1012 of the drying cavity and first enters the main air duct 2201 through the air inlet 1011 of the main air duct 2201. Understandably, since the filter screen assembly 10 is installed in the main air duct 2201 and located at the air inlet 1011, the air flow carrying lint and water vapor first passes through the filtration of the filter screen assembly 10, and the lint, fibers and other impurities in the air are intercepted on the outer circumferential surface of the first filter screen 12, and the clean air after filtration continues to flow in the main air duct 2201. After the air reaches the air outlet 1012 of the main air duct 2201, it enters the branch air duct, which guides the air to the drying cavity to dehumidify the clothes in the drying cavity again, and the air carrying moisture flows out of the drying cavity and returns to the main air duct 2201 again through the branch air duct, completing a circulation process. In this circulation process, the filter screen assembly 10 continuously filters the air entering the main air duct 2201 to ensure that the air in the entire circulating air duct 220 is relatively clean.

[0078] It should be noted that the base 2101 is provided with an opening communicating with the main air duct 2201, and the filter device 100 can be installed in the main air duct 2201 through the opening or disassembled from the main air duct 2201 through the opening. When the handle assembly 20 is installed on the filter assembly, the second plate body 2111 is in sealing cooperation with the edge of the opening and closes the opening, on the one hand, when cleaning the lint accumulated on the first filter screen 12, the handle bracket 21 can be directly pulled out of the filter assembly through the opening, which is simple and convenient, and on the other hand, the second plate body 2111 closing the opening can prevent the hot and humid air from leaking to the outside of the clothes treatment device 200.

[0079] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
