[0071] Embodiments of the present application are described in detail below with reference to examples illustrated in the accompanying drawings, in which the same or similar components have the same or similar designations throughout the various figures. The embodiments described below are examples of the present application and are not intended to limit the present application.

[0072] Reference is made below to Figures 1-29 A filter device 100 according to an embodiment of the present application is described.

[0073] Reference is made below to Figures 1-5 According to some embodiments, the filter device 100 comprises a first filter assembly 10, a mounting member 22 and a first cleaning member 30. The first filter assembly 10 comprises a first filter screen 11, the mounting member 22 is movable along a length direction of the first filter screen 11, and the first cleaning member 30 is arranged on the mounting member 22 so as to be movable together with the mounting member 22.

[0074] Specifically, the first filter screen 11 has a first end 111 (e.g. a front end) and a second end 112 (e.g. a rear end) in a length direction (e.g. a front-rear direction) of the first filter screen 11. Figure 2 Figure 2 Figure 2

[0075] Under the driving of the mounting member 22, the first cleaning member 30 is movable along the length direction of the first filter screen 11 from the first end 111 of the first filter screen 11 to the second end 112 of the first filter screen 11, and is also movable along the length direction of the first filter screen 11 from the second end 112 of the first filter screen 11 to the first end 111 of the first filter screen 11. That is, under the driving of the mounting member 22, the first cleaning member 30 is movable along a front-to-rear direction from the front end of the first filter screen 11 to the rear end of the first filter screen 11, and is also movable along a rear-to-front direction from the rear end of the first filter screen 11 to the front end of the first filter screen 11.

[0076] ​​​The mounting member 22 is arranged to be movable along the length direction of the first filter screen 11, so that the first cleaning member 30 can clean the first filter screen 11 along the length direction of the first filter screen 11. In this way, the first filter screen 11 can be cleaned during the movement of the mounting member 22, and additional cleaning functions can be achieved by the movement of the mounting member 22, which saves time and effort. In addition, the size of the first cleaning member 30 can be reduced, so that the structural size of the first cleaning member 30 can be reduced, the cost of the first cleaning member 30 can be reduced, and the occupied space of the first cleaning member 30 can be reduced, thereby facilitating the miniaturization design of the filter device 100.

[0077] In some embodiments, with reference to Figures 5-7 The first cleaning member 30 is rotatably arranged on the mounting member 22 and is switchable between a first state and a second state. In the first state, the first cleaning member 30 is in abutting cooperation with the first filter screen 11. In the second state, the first cleaning member 30 is out of cooperation with the first filter screen 11.

[0078] The filter device 100 comprises a first driving member. The first cleaning member 30 is provided with a pushing part 36. The pushing part 36 is adapted to drive the first cleaning member 30 to rotate under the action of the first driving member, so as to switch the state of the first cleaning member 30.

[0079] According to the filter device 100 of the embodiment of the present application, the first driving member is arranged, the first cleaning member 30 is rotatably arranged on the mounting member 22, the pushing part 36 is arranged on the first cleaning member 30, the first cleaning member 30 is cooperated with the first driving member through the pushing part 36, and the pushing part 36 drives the first cleaning member 30 to rotate under the action of the first driving member during the movement of the mounting member 22 along the length direction of the first filter screen 11. The first cleaning member 30 can be switched from the second state to the first state, so that the first filter screen 11 can be cleaned by the first cleaning member 30, and the first cleaning member 30 can be switched from the first state to the second state, so that the first cleaning member 30 avoids the first filter screen 11 and reduces the abrasion of the first cleaning member 30, thereby prolonging the service life of the first cleaning member 30. The whole cleaning process is convenient to operate, and is conducive to reducing the maintenance cost of the filter device 100.

[0080] It should be noted that the first driving member can be an electric structure or a mechanical structure, and the specific structure is not limited. The installation position of the first driving member is not limited, and the first driving member can be arranged on the first filter assembly 10, arranged on the mounting member 22, or arranged on an intermediate member.

[0081] According to some embodiments of the present application, the first driving member is arranged on the first filter assembly 10. That is, the actuating portion 36 is matched with the first filter assembly 10 through the first driving member, so that the first cleaning member 30 is matched with the first filter assembly 10 during the movement of the mounting member 22, and the power and movement transmission are realized.

[0082] According to some embodiments of the present application, the first driving member is arranged on the first filter assembly 10. That is, the actuating portion 36 is matched with the first filter assembly 10 through the first driving member, so that the first cleaning member 30 is matched with the first filter assembly 10 during the movement of the mounting member 22, and the power and movement transmission are realized.

[0083] With reference to Figures 5-7 According to some embodiments of the present application, the actuating portion 36 is a movable shaft, and the central axis of the movable shaft is arranged in parallel with or coincides with the rotation axis of the first cleaning member 30.

[0084] In the example that the central axis of the movable shaft is arranged in parallel with the rotation axis of the first cleaning member 30, the rotation axis of the first cleaning member 30 is fixed relative to the mounting member 22, the movable shaft is driven to move by the first driving member, and the movable shaft can rotate around the rotation axis of the first cleaning member 30, so that the first cleaning member 30 can rotate.

[0085] In the example that the central axis of the movable shaft coincides with the rotation axis of the first cleaning member 30, the first driving member can directly drive the movable shaft to rotate, so that the first cleaning member 30 can rotate.

[0086] In this way, on the one hand, the structure layout can be compact, and the space utilization rate can be improved, and on the other hand, the power transmission can be more stable, and the reliability of the rotation of the first cleaning member relative to the mounting member can be ensured.

[0087] With reference to Figure 13 and Figure 16 According to some embodiments of the present application, the actuating portion 36 is matched with the first filter assembly 10 in sliding mode during the movement of the mounting member 22 along the length direction of the first filter screen 11.

[0088] In the above technical solution, the actuating portion 36 is matched with the first filter assembly 10 in sliding mode, on the one hand, the actuating portion 36 can prevent the movement of the mounting member 22 and the first cleaning member 30 along the length direction of the first filter screen 11, and ensure that the first cleaning member 30 can normally clean the first filter screen 11, and on the other hand, the actuating portion 36 can drive the first cleaning member 30 to rotate under the action of different parts of the first filter assembly 10, so that the state of the first cleaning member 30 can be changed as needed, and different use requirements can be met.

[0089] In some embodiments, referring to Figure 4 , Figure 12 , Figure 16 , Figure 26 In some embodiments, the first filter assembly 10 has a first guide slot 1231 and a second guide slot 1241, which are located on one side of the thickness direction (e.g. the up-down direction as shown in the figure) of the first filter screen 11 and arranged in the thickness direction of the first filter screen 11. Figure 4

[0090] In the above technical solution, by arranging the first guide slot 1231 and the second guide slot 1241 on the first filter assembly 10, and by controlling the switching of the driving part 36 with the first guide slot 1231 and the second guide slot 1241, the driving part 36 can drive the first cleaning part 30 to change the state, so as to meet different use requirements.

[0091] In the above technical solution, by arranging the first guide slot 1231 and the second guide slot 1241 on the first filter assembly 10, and by controlling the switching of the driving part 36 with the first guide slot 1231 and the second guide slot 1241, the driving part 36 can drive the first cleaning part 30 to change the state, so as to meet different use requirements.

[0092] In some embodiments, referring to Figure 12 , Figure 16 and Figure 18 In some embodiments, the first filter assembly 10 includes a separation part 14, which extends along the length direction of the first filter screen 11 and separates the first guide slot 1231 and the second guide slot 1241 to realize the operation of the first state and the second state.

[0093] In some embodiments, the first driving part includes a driving part 13, which is arranged on the first filter assembly 10. The driving part 13 is located at one end of the separation part 14 and spaced apart from the separation part 14. The driving part 36 is adapted to drive the first cleaning part 30 to rotate under the action of the driving part 13, so as to switch the state of the first cleaning part 30.

[0094] In the process of moving the first cleaning part 30 along the length direction of the first filter screen 11, when the driving part 36 on the first cleaning part 30 contacts the driving part 13, as the first cleaning part 30 continues to move along the length direction of the first filter screen 11, the driving part 36 slides on the driving part 13, so as to drive the first cleaning part 30 to rotate and realize the purpose of changing the state of the first cleaning part 30.

[0095] ​Therefore, by setting the first driving member to include the driving portion 13 arranged on the first filter assembly 10, the first filter assembly 10 can be used as a carrier of the driving portion 13, facilitating the cooperation between the first filter assembly 10 and the poking portion 36 by the driving portion 13, so that the movement path of the poking portion 36 can be changed by the driving portion 13, and the poking portion 36 can drive the first cleaning member 30 to rotate, thereby changing the state of the first cleaning member 30 and meeting different use requirements.

[0096] In some embodiments, the number of the first guide grooves 1231 and the second guide grooves 1241 can be multiple, respectively. The multiple first guide grooves 1231 are arranged at intervals in the length direction of the first filter screen 11, and the multiple second guide grooves 1241 are arranged at intervals in the length direction of the first filter screen 11. The multiple first guide grooves 1231 and the multiple second guide grooves 1241 correspond to each other in the thickness direction of the first filter screen 11.

[0097] In some embodiments, the driving portion 13 can include a first driving portion 125, which is located between two adjacent second guide grooves 1241. During the movement of the first cleaning member 30 in the length direction of the first filter screen 11, when the poking portion 36 on the first cleaning member 30 contacts the first driving portion 125, the poking portion 36 slides on the first driving portion 125 as the first cleaning member 30 continues to move in the length direction of the first filter screen 11, thereby driving the first cleaning member 30 to rotate, i.e., changing the state of the first cleaning member 30 at the middle position in the length direction of the first filter screen 11.

[0098] In other embodiments, the number of the first guide grooves 1231 and the second guide grooves 1241 can be one, respectively. The first guide groove 1231 and the second guide groove 1241 both extend from one end of the length direction of the first filter screen 11 to the other end of the length direction of the first filter screen 11. Alternatively, the number of the first guide grooves 1231 and the second guide grooves 1241 can be multiple, respectively. The multiple first guide grooves 1231 are arranged at intervals in the length direction of the first filter screen 11, and the multiple second guide grooves 1241 are arranged at intervals in the length direction of the first filter screen 11. The multiple first guide grooves 1231 and the multiple second guide grooves 1241 correspond to each other in the thickness direction of the first filter screen 11.

[0099] In some embodiments, the drive unit 13 may include a second drive unit 126 located at one end of the length direction of the first filter screen 11. During the movement of the first cleaning member 30 along the length direction of the first filter screen 11, when the actuating part 36 on the first cleaning member 30 contacts the second drive unit 126, as the first cleaning member 30 continues to move along the length direction of the first filter screen 11, the actuating part 36 slides on the second drive unit 126, thereby driving the first cleaning member 30 to rotate, that is, changing the state of the first cleaning member 30 at one end of the length direction of the first filter screen 11.

[0100] It should be noted that the first drive unit 125 and the second drive unit 126 may be the same or different; only one first drive unit 125 may be provided, only one second drive unit 126 may be provided, or both first drive units 125 and second drive units 126 may be provided simultaneously. By providing the first drive unit 125 and the second drive unit 126, that is, by providing two sets of drive units 13, it can be ensured that the first cleaning component 30 has multiple turning points during its movement along the length direction of the first filter screen 11, giving the user more choices and ensuring that the first cleaning component 30 is in the first state for cleaning the filter screen regardless of which drive unit 13 the user turns at.

[0101] Reference Figure 12 , Figure 16 and Figure 18 In some examples, the drive section 13 has a first drive surface 1251 on the side facing the separator 14, in the thickness direction of the first filter screen 11 (as shown in the attached figure). Figure 12 (In the vertical direction), the first driving surface 1251 extends obliquely from the second guide groove 1241 to the first guide groove 1231 in a direction away from the partition 14, for driving the toggle part 36 to slide out from the second guide groove 1241 and switching the first cleaning part 30 from the second state to the first state.

[0102] For example, the first driving surface 1251 can be an inclined surface or an arc surface.

[0103] The first driving surface 1251 is provided on the drive unit 13. On the one hand, it can serve as a guide, allowing the actuating part 36 to move along the extension direction of the first driving surface 1251, thereby sliding out from the second guide groove 1241. This allows the first cleaning component 30 to rotate under the drive of the actuating part 36, switching from the second state to the first state. On the other hand, it can also serve as a buffer, reducing the impact force of the actuating part 36 on the drive unit 13, reducing the probability of breakage between the actuating part 36 and the first cleaning component 30, and extending the service life of the filter device 100.

[0104] Reference Figure 16 and Figure 18In some specific examples, the partition 14 has a first guide surface 1271 at the end opposite to the first driving surface 1251. In the thickness direction of the first filter screen 11, the first guide surface 1271 extends from the second guide groove 1241 to the first guide groove 1231 in a direction away from the first driving surface 1251, and is used to guide the sliding of the poking portion 36 into the first guide groove 1231 from the driving portion 13.

[0105] For example, the first guide surface 1271 can be a slope or an arc surface.

[0106] The first guide surface 1271 provided at the end of the partition 14 can serve as a guide, so that the poking portion 36 can move along the extension direction of the first guide surface 1271 and thus can slide into the first guide groove 1231, so that the first cleaning member 30 can be kept in the first state.

[0107] Referring to Figure 16 and Figure 17 In some examples, the end of the partition 14 away from the driving portion 13 has a second guide surface 1272. In the thickness direction of the first filter screen 11, the second guide surface 1272 extends from the second guide groove 1241 to the first guide groove 1231 in a direction away from the driving portion 13, and is used to guide the sliding of the poking portion 36 into the second guide groove 1241, so that the first cleaning member 30 can be switched from the first state to the second state.

[0108] For example, the second guide surface 1272 can be a slope or an arc surface.

[0109] The second guide surface 1272 provided at the other end of the partition 14 can serve as a guide, so that the poking portion 36 can move along the extension direction of the second guide surface 1272 and thus can slide into the second guide groove 1241, so that the first cleaning member 30 can be switched to the second state.

[0110] Referring to Figure 14 and Figure 16 In some examples, the first filter screen 11 has a first end 111 and a second end 112 in the length direction, and the partitions 14 and the driving portions 13 are arranged in groups. The driving portion 13 in a group is located on the side of the partition 14 closer to the second end 112.

[0111] That is, in the groups of the partitions 14 and the driving portions 13, the partitions 14 and the driving portions 13 are arranged sequentially in the direction from the first end 111 to the second end 112. The partition 14 is arranged closer to the first end 111 of the first filter screen 11 than the driving portion 13, and the driving portion 13 is arranged closer to the second end 112 of the first filter screen 11 than the partition 14.

[0112] Specifically Figure 16The first driving surface 1251 of the driving portion 13 gradually extends backward from the second guide groove 1241 to the first guide groove 1231. The first guide surface 1271 of the partition portion 14 gradually extends forward from the second guide groove 1241 to the first guide groove 1231. The second guide surface 1272 of the partition portion 14 gradually extends forward from the second guide groove 1241 to the first guide groove 1231.

[0113] In the process that the first cleaning piece 30 moves from front to back along the length direction of the first filter screen 11 and the toggle portion 36 on the first cleaning piece 30 cooperates with the second guide groove 1241, when the toggle portion 36 on the first cleaning piece 30 contacts the first driving surface 1251 of the driving portion 13, the toggle portion 36 slides on the first driving surface 1251 as the first cleaning piece 30 continues to move backward, so that the toggle portion 36 slides out of the second guide groove 1241 and can drive the first cleaning piece 30 to rotate, achieving the purpose of switching the first cleaning piece 30 from the second state to the first state.

[0114] In the process that the first cleaning piece 30 moves from back to front along the length direction of the first filter screen 11, the toggle portion 36 on the first cleaning piece 30 can slide into the first guide groove 1231 from the driving portion 13 under the guidance of the first guide surface 1271, so that the first cleaning piece 30 remains in the first state.

[0115] In the process that the first cleaning piece 30 moves from front to back along the length direction of the first filter screen 11 and the first cleaning piece 30 is in the first state, the toggle portion 36 on the first cleaning piece 30 can slide into the second guide groove 1241 under the guidance of the second guide surface 1272, so that the first cleaning piece 30 switches from the first state to the second state.

[0116] Therefore, by arranging the partition portion 14 and the driving portion 13 in groups, the toggle portion can be switched to slide into the first guide groove 1231 and the second guide groove 1241 under the action of the partition portion 14 and the driving portion 13, so as to achieve the state switching of the first cleaning piece 30.

[0117] Referring to Figure 4 , Figure 16 , Figure 26In some examples, the partition portions 14 and the driving portions 13 are provided in one or more groups, wherein the driving portion 13 in one group has a second driving surface 1252 on the side facing the partition portion 14 in the other group adjacent thereto, which extends in a direction away from the partition portion 14 from the second guide groove 1241 to the first guide groove 1231 in the thickness direction of the first filter screen 11, for driving the poking portion 36 to slide out of the second guide groove 1241 and switching the first cleaning member from the second state to the first state.

[0118] Specifically, in the case where the partition portions 14 and the driving portions 13 are provided in multiple groups, the multiple partition portions 14 and the multiple driving portions 13 are arranged alternately in the direction from the first end 111 to the second end 112. An embodiment in which the partition portions 14 and the driving portions 13 are provided in two groups is described below.

[0119] The partition portions 14 include a first partition portion 127 and a second partition portion 128, which are arranged in the direction from the first end 111 to the second end 112. The driving portions 13 include a first driving portion 125 and a second driving portion 126, which are arranged in the direction from the first end 111 to the second end 112. The first partition portion 127 and the first driving portion 125 are provided in a first group, and the first partition portion 127 and the first driving portion 125 are arranged in the direction from the first end 111 to the second end 112. The second partition portion 128 and the second driving portion 126 are provided in a second group, and the second partition portion 128 and the second driving portion 126 are arranged in the direction from the first end 111 to the second end 112.

[0120] For the first group, the first driving portion 125 has a first driving surface 1251 on the side facing the first partition portion 127, the first partition portion 127 has a first guide surface 1271 on the end close to the first driving portion 125, and the first partition portion 127 has a second guide surface 1272 on the end away from the first driving portion 125.

[0121] For the second group, the second driving portion 126 has a third driving surface 1261 (corresponding to the first driving surface 1251 of the driving portion 13) on the side facing the second partition portion 128, the second partition portion 128 has a third guide surface 1281 (corresponding to the first guide surface 1271 of the partition portion 14) on the end close to the second driving portion 126, and the second partition portion 128 has a fourth guide surface 1282 (corresponding to the second guide surface 1272 of the partition portion 14) on the end away from the second driving portion 126.

[0122] In addition, the first driving part 125 in the first group has a second driving surface 1252 facing one side of the second partition part 128 in the second group, when the poking part 36 moves in the second guide groove 1241 in the direction from the second end 112 to the first end 111, the second driving surface 1252 can drive the poking part 36 to slide out of the second guide groove 1241, and make the first cleaning piece 30 switch from the second state to the first state.

[0123] Therefore, by setting the partition part 14 and the driving part 13 as one group or multiple groups, the first cleaning piece 30 can be switchably slid into the first guide groove 1231 and the second guide groove 1241 during the movement of the mounting piece 22 along the length direction of the first filter screen 11, so as to realize the state switching of the first cleaning piece 30.

[0124] In some embodiments, in the case of multiple groups of partition parts 14 and driving parts 13, the partition part 14 in one group includes one or more partition parts 14 which are arranged at intervals.

[0125] For example, for the above-mentioned first group, the number of partition parts 14 is one, which is the first partition part 127. For the above-mentioned second group, the number of partition parts 14 is two, which are two second partition parts 128. Of course, the partition parts 14 of the second group can also be one.

[0126] In this way, on the one hand, the production process of the first filter assembly 10 can be simplified, and the mold can be easily removed. On the other hand, the poking part 36 can switch the guide groove between the two partition parts 14 as needed, so that the first cleaning piece 30 has more turning points, meeting the diverse needs of users.

[0127] Reference Figures 4-6 In some embodiments, the first filter assembly 10 also has a sliding groove 129 extending along the length direction of the first filter screen 11 and located on the side of the second guide groove 1241 away from the first guide groove 1231, and the mounting piece 22 has a sliding protrusion 226 which is in sliding cooperation with the sliding groove 129 during the movement of the mounting piece 22 along the length direction of the first filter screen 11.

[0128] In the above technical solution, the sliding groove 129 and the sliding protrusion 226 are used in cooperation, which can guide and limit the sliding direction of the mounting piece 22, ensuring the stability of the movement of the mounting piece 22.

[0129] In some examples, the sliding groove 129 and the second guide groove 1241 are separated by a limiting part 1290 extending along the length direction of the first filter screen 11, and the driving part 13 can be arranged on the side of the limiting part 1290 facing the second guide groove 1241, that is, the driving part 13 can protrude from the side surface of the limiting part 1290 facing the second guide groove 1241.

[0130] According to some embodiments of the present application, the first cleaning member 30 is adapted to clean the first filter screen 11 in the first state and the state in which the mounting member 22 moves in the first direction, which is the direction of the length of the first filter screen 11 pointing to one end. The first direction here is the F1 direction in Figure 24 , and specifically can be the direction from back to front in Figure 24 .

[0131] In this way, the operator can use the first cleaning member 30 to clean the first filter screen 11 in one direction, which can prevent the first cleaning member 30 from scratching the first filter screen 11 back and forth, causing secondary pollution, improve the cleaning effect of the first cleaning member 30 on the first filter screen 11, improve the cleaning efficiency, reduce the number of operations of the operator, and improve the user experience of the operator.

[0132] Referring to Figure 1 , Figures 5-9 , in some embodiments, the filtering device 100 further comprises a second filter screen 21 and a second cleaning member 40, the second filter screen 21 is arranged on the mounting member 22 to move together with the mounting member 22, and the second filter screen 21 and the mounting member 22 can be combined to form a second filter assembly 20.

[0133] In some embodiments, the filtering device 100 further comprises a second cleaning member 40, which is arranged on the first filter assembly 10 and used to clean the second filter screen 21.

[0134] In the above technical solution, by arranging the second filter screen 21, i.e. arranging at least two layers of filter screens in total, the effect of filtering the fluff can be improved, and by arranging the second cleaning member 40 on the first filter assembly 10, the second filter screen 21 and the second cleaning member 40 can move relative to each other during the movement of the second filter screen 21 relative to the first filter assembly 10 driven by the mounting member 22, so that the second cleaning member 40 can be used to clean the second filter screen 21.

[0135] In some examples, the second cleaning member 40 is adapted to clean the second filter screen 21 in the state in which the mounting member 22 moves in the second direction, which is different from the first direction.

[0136] In this way, the operator can use the second cleaning member 40 to clean the second filter screen 21 in one direction, which can prevent the second cleaning member 40 from scratching the second filter screen 21 back and forth, causing secondary pollution, improve the cleaning effect of the second cleaning member 40 on the second filter screen 21, improve the cleaning efficiency, reduce the number of operations of the operator, and improve the user experience of the operator.

[0137] Furthermore, the first filter screen 11 is cleaned when the mounting component 22 moves in the first direction, and the second filter screen 21 is cleaned when the mounting component 22 moves in the second direction. The user only needs to pull it out once to clean both filters, making the operation simple and reliable. In addition, the cleaning time of the first filter screen 11 and the second filter screen 21 is not simultaneous and the cleaning direction is different. Therefore, during the cleaning process, the lint on the first filter screen 11 and the second filter screen 21 can be prevented from contaminating each other, which is beneficial to improving the cleaning effect and cleaning efficiency of the first filter screen 11 and the second filter screen 21.

[0138] In some specific examples, the second direction is opposite to the first direction. Here, the second direction is... Figure 14 The F2 direction in the text can be specifically... Figure 14 The direction from front to back.

[0139] Specifically, when the filter device 100 is in its initial state, the operator can drive the second filter assembly 20 to move along the second direction, causing the second filter screen 21 to move relative to the first cleaning member 30 along the second direction, thereby enabling the second cleaning member 40 to clean the second filter screen 21; the operator can also drive the second filter assembly 20 to move along the second direction, causing the first cleaning member 30 to move relative to the first filter screen 11 along the first direction, thereby enabling the first cleaning member 30 to clean the first filter screen 11; in addition, the operator can also reset the second filter assembly 20, so that the filter device 100 returns to its initial state.

[0140] Therefore, in the above technical solution, by setting the second direction and the first direction to be opposite, the first filter screen 11 and the second filter screen 21 can be cleaned during the process of driving the second filter component 20 to move back and forth. The second filter component 20 can also be reset, which helps to reduce the cleaning time of the filter device 100, improve the cleaning efficiency of the filter device 100, and enhance the user experience.

[0141] The following is in conjunction with the appendix Figures 1-29 Some specific embodiments of the filtration device 100 according to the present invention are described.

[0152] That is, the chip removal area 1224 is located in the area of the through hole 1221 close to the second end 112, i.e. the chip removal area 1224 is located in the rear area of the through hole 1221. The chip removal part gradually extends inwardly into the mounting cavity 120 from front to rear. Specifically, the angle α between the chip removal part 1225 and the first filter screen 11 is 30°-60°, for example, α can be 30°, 45°, 60°, etc.

[0188] In some specific examples, the mounting cavity 120 has a third cavity wall 1227 and a fourth cavity wall 1228, the third cavity wall 1227 and the fourth cavity wall 1228 are oppositely arranged in the width direction of the mounting box 12, and the first guide part 123, the second guide part 124, the first driving part 125 and the second driving part 126 are arranged on the third cavity wall 1227 and the fourth cavity wall 1228.

[0189] With reference to Figures 4-6 In some embodiments, the first filter assembly 10 further has a sliding groove 129, for example, the third cavity wall 1227 and the fourth cavity wall 1228 of the mounting cavity 120 can be provided with the sliding groove 129. The sliding groove 129 can extend along the length direction of the first filter screen 11, and is located on the side of the second guide groove 1241 away from the first guide groove 1231, the sliding groove 129 is separated from the second guide groove 1241 by a limiting part 1290, the mounting piece 22 has a sliding protrusion 226, during the movement of the mounting piece 22 along the length direction of the first filter screen 11, the sliding protrusion 226 is in sliding cooperation with the sliding groove 129, so as to ensure the stability of the movement of the mounting piece 22.

[0190] The cleaning process and the mounting and dismounting process of the filter device 100 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0191] For the convenience of understanding, with reference to Figures 8-12 , the direction of the length direction of the first filter screen 11 pointing to the first end 111 is defined as the first direction, that is, the first direction is the rear-to-front direction in Figure 9 , and the direction of the length direction of the first filter screen 11 pointing to the second end 112 is defined as the second direction, that is, the second direction is the front-to-rear direction in Figure 9 .

[0192] It is defined that in the initial state of the filter device 100, the second filter assembly 20 is in the first position, at this time, the second filter screen 21 is completely accommodated in the mounting cavity 120 of the first filter assembly 10, and the first cleaning piece 30 is close to the chip removal opening 1202 of the mounting cavity 120 and is in the first state, and the second cleaning piece 40 is close to the opening 1201 of the mounting cavity 120.

[0193] When the filter device 100 needs to be cleaned, the second filter assembly 20 can be pulled in the second direction first, so that the second filter assembly 20 can be moved from the first position to the second position relative to the first filter assembly 10 in the second direction, so that the second filter assembly 20 gradually extends out of the opening 1201 of the mounting cavity 120.

[0194] Since the second cleaning piece 40 is arranged at the first filter assembly 10, the position of the second cleaning piece 40 is always fixed, the second filter assembly 20 moves relative to the second cleaning piece 40 along the second direction, and the second cleaning piece 40 moves relative to the second filter assembly 20 along the first direction, so that the second cleaning piece 40 can scrape the air inlet side of the second filter screen 21 along the first direction relative to the second filter assembly 20 by using the second cleaning protrusions 411, thereby pushing the lint on the second filter screen 21 away from one end of the handle 224 (i.e., the front end of the second filter screen 21), and finally falling from the lint removal area 1224, while the lint removal part 1225 can always keep the lint on the second filter screen 21 at the lint removal area 1224, preventing the lint from entering the installation cavity 120 again.

[0195] With reference to Figures 13-17 In this process, the first cleaning piece 30 moves along the second direction together with the second filter assembly 20, the pushing part 36 on the first cleaning piece 30 is guided by the second guide surface 1272 of the first separation part 127 to slide into the second guide groove 1241 close to the lint removal port 1202 of the installation cavity 120, and the first cleaning piece 30 can rotate under the drive of the pushing part 36 and switch from the first state to the second state; as the second filter assembly 20 and the first cleaning piece 30 continue to move along the second direction, the pushing part 36 is always in sliding fit with the second guide groove 1241, so that the first cleaning piece 30 remains in the second state and is spaced apart from the first filter screen 11, and cannot realize cleaning of the first filter screen 11.

[0196] With reference to Figure 18 When the pushing part 36 moves along the second direction to the state of abutting against the first driving part 125, the pushing part 36 slides out of the second guide groove 1241 under the drive of the first driving surface 1251 of the first driving part 125, and the first cleaning piece 30 can rotate under the drive of the pushing part 36 and switch from the second state to the first state.

[0197] As the second filter assembly 20 and the first cleaning piece 30 continue to move along the second direction, the pushing part 36 on the first cleaning piece 30 is guided by the fourth guide surface 1282 of the second separation part 128 to slide into the second guide groove 1241 close to the opening 1201 of the installation cavity 120, and the first cleaning piece 30 can rotate under the drive of the pushing part 36 and switch from the second state to the first state; as the second filter assembly 20 and the first cleaning piece 30 continue to move along the second direction, the pushing part 36 is always in sliding fit with the second guide groove 1241, so that the first cleaning piece 30 remains in the second state and is spaced apart from the first filter screen 11, and cannot realize cleaning of the first filter screen 11.

[0198] With reference to Figure 19When the dial part 36 moves to the state of abutting against the second driving part 126 along the second direction, the dial part 36 slides out of the second guide groove 1241 under the driving of the third driving surface 1261 of the second driving part 126, the first cleaning part 30 can rotate under the driving of the dial part 36, and switch from the second state to the first state.

[0199] In summary, in the process of pulling the second filter assembly 20 along the second direction, the second cleaning protrusion 411 of the second cleaning part 40 can scrape the air inlet side of the second filter screen 21 to clean the second filter screen 21, and in this process, when the first cleaning part 30 is in the second state, the first cleaning protrusion 3111 of the first cleaning part 30 is disengaged from the first filter screen 11, so it cannot scrape the first filter screen 11, that is, it cannot clean the first filter screen 11, when the first cleaning part 30 is in the first state, the first guide arc surface 3121 of the first cleaning part 30 can play a guiding role, so that the first cleaning part 30 slides smoothly on the first filter screen 11, the first cleaning protrusion 3111 of the first cleaning part 30 cannot scrape the first filter screen 11, so the first cleaning part 30 cannot clean the first filter screen 11.

[0200] Referring to Figures 20-22 When the second filter assembly 20 moves to the second position, the second filter assembly 20 can be first pushed along the first direction, so that the second filter assembly 20 moves relative to the first filter assembly 10 along the first direction from the second position to the first position, so that the second filter assembly 20 gradually extends into the mounting cavity 120 from the opening 1201 of the mounting cavity 120.

[0201] Since the second cleaning part 40 is arranged on the first filter assembly 10, the position of the second cleaning part 40 is always fixed, and the second filter assembly 20 moves relative to the second cleaning part 40 along the first direction, so that the second guide arc surface 412 of the second cleaning part 40 can play a guiding role, so that the second cleaning part 40 slides smoothly on the second filter screen 21, and the second cleaning protrusion 411 of the second cleaning part 40 cannot scrape the second filter screen 21, so the second cleaning part 40 cannot clean the second filter screen 21.

[0202] Referring to Figures 23-26In the process, the first cleaning piece 30 moves along with the second filter assembly 20 in the first direction, the poking part 36 on the first cleaning piece 30 is guided by the third guide surface 1281 of the second separation part 128 to slide into the first guide groove 1231 close to the opening 1201 of the mounting cavity 120, and as the second filter assembly 20 and the first cleaning piece 30 continue to move in the first direction, the poking part 36 is always in sliding fit with the first guide groove 1231, so that the first cleaning piece 30 is kept in the first state, so that the first cleaning protrusion 3111 of the first cleaning piece 30 can scrape the air inlet side of the first filter screen 11, realize cleaning of the first filter screen 11, and push the dust of the first filter screen 11 to gradually approach the dust discharge port 1202 of the mounting cavity 120, and finally push the dust out of the dust discharge port 1202.

[0203] In summary, in the process of pushing the second filter assembly 20 in the first direction, the first cleaning protrusion 3111 of the first cleaning piece 30 can scrape the air inlet side of the first filter screen 11 to realize cleaning of the first filter screen 11, and in the process, the second guide arc surface 412 of the second cleaning piece 40 can play a guiding role to make the second cleaning piece 40 smoothly slide along the second filter screen 21, the second cleaning protrusion 411 of the second cleaning piece 40 cannot scrape the second filter screen 21, so the second cleaning piece 40 cannot realize cleaning of the second filter screen 21.

[0204] Referring to Figure 18 It should be noted that in the process of pulling the second filter assembly 20 in the second direction, when the poking part 36 slides out of the second guide groove 1241 under the drive of the first drive surface 1251 of the first drive part 125, the first cleaning piece 30 is switched from the second state to the first state, at this time, the second filter assembly 20 can also be pushed in the first direction, so that the poking part 36 on the first cleaning piece 30 is guided by the first guide surface 1271 of the first separation part 127 to slide into the first guide groove 1231 close to the dust discharge port 1202 of the mounting cavity 120, and as the second filter assembly 20 and the first cleaning piece 30 continue to move in the first direction, the poking part 36 is always in sliding fit with the first guide groove 1231, so that the first cleaning piece 30 is kept in the first state, so that the first cleaning protrusion 3111 of the first cleaning piece 30 can scrape the first filter screen 11 to realize cleaning of part of the first filter screen 11, and the dust of the first filter screen 11 is pushed by the dust pushing part 32 and the first cleaning part 31 to gradually approach the dust discharge port 1202 of the mounting cavity 120, and finally pushed out of the dust discharge port 1202.

[0205] When the first filter assembly 10 and the second filter assembly 20 need to be separated for cleaning or washing, the second filter assembly 20 can be pulled in the second direction first, so that the second filter assembly 20 can be moved in the second direction from the first position to the second position relative to the first filter assembly 10, and the second filter assembly 20 gradually extends out of the opening 1201 of the mounting cavity 120; then the mounting portion 2211 on the frame 221 of the second filter assembly 20 is pressed manually, so that the first stopper 222 on the mounting portion 2211 is disengaged from the mounting box 12 of the first filter assembly 10, and thus the second filter assembly 20 can be taken out of the opening 1201 of the mounting cavity 120, and the first filter assembly 10 and the second filter assembly 20 are separated.

[0206] When the first filter assembly 10 and the second filter assembly 20 are cleaned or washed respectively, the second filter assembly 20 can be aligned with the opening 1201 of the mounting cavity 120, and then the mounting portion 2211 on the frame 221 of the second filter assembly 20 is pressed, so that the first stopper 222 on the mounting portion 2211 is clamped into the mounting box 12; then the second filter assembly 20 is pushed in the first direction, so that the second filter assembly 20 is moved from the second position to the first position, that is, the filter device 100 is in the initial state, and subsequent use is facilitated.

[0207] Therefore, according to the filter device 100 of the embodiment of the present application, by arranging the first cleaning member 30 on the second filter assembly 20 and arranging the second cleaning member 40 on the first filter assembly 10, when the second filter assembly 20 moves relative to the first filter assembly 10 in the first direction and the second direction, the first cleaning member 30 and the first filter screen 11 can move relative to each other, and the second cleaning member 40 and the second filter screen 21 can move relative to each other, so that the first filter screen 11 and the second filter screen 21 can be cleaned respectively. Since the cleaning time of the first filter screen 11 and the second filter screen 21 is not simultaneous and the cleaning directions are different, in the cleaning process, the lint on the first filter screen 11 and the second filter screen 21 can be prevented from contaminating each other, and the cleaning effect and the cleaning efficiency of the first filter screen 11 and the second filter screen 21 can be improved.

[0208] In some embodiments, the first filter assembly 10 and the mounting member 22 have a combined state and a movable state. In the combined state, the first filter assembly 10 and the mounting member 22 can be inserted into or taken out of the laundry treatment apparatus as a whole, and a part of the mounting member 22 is arranged on the outer facade of the laundry treatment apparatus, so that the user can easily see the mounting member 22 and easily install and dismount the whole assembly. In addition, the mounting member 22 can also be moved or dismounted in the first filter assembly 10, that is, the mounting member 22 can be taken out of the laundry treatment apparatus as a whole and also serves as a tool for cleaning the first filter screen 11, so that one object has multiple functions, which is convenient and practical.

[0209] In some embodiments, referring to Figures 27-29 One of the mounting member 22 and the cavity wall of the mounting cavity 120 is provided with a second stopper 225, and the other is provided with a matching component 2253. The second stopper 225 and the matching component 2253 match with each other, so that the mounting member 22 can be locked in the first position even if the first filter assembly 10 and the mounting member 22 are in the combined state.

[0210] Specifically, when the mounting member 22 is in the first position, the matching component 2253 stops the second stopper 225, preventing the mounting member 22 from moving to the second position.

[0211] In some examples, one of the mounting member 22 and the cavity wall of the mounting cavity 120 has a limiting slot 2230, and the second stopper 225 is movably arranged in the limiting slot 2230. The other of the mounting member 22 and the cavity wall of the mounting cavity 120 is provided with a matching component 2253, and the matching component 2253 has a first matching inclined surface 22531 and a second matching inclined surface 22532 arranged opposite to each other in the length direction of the first filter screen 11. The second matching inclined surface 22532 is closer to the first end 111 of the first filter screen 11 than the first matching inclined surface 22531.

[0212] For example, the second stopper 225 includes an elastic component 2251 and a moving component 2252. The elastic component 2251 is arranged in the limiting slot 2230, one end of the elastic component 2251 is connected with the slot wall of the limiting slot 2230, and the other end is connected with the moving component 2252. By arranging the elastic component 2251, the moving component 2252 can move in the limiting slot 2230 under the action of the matching component 2253, and the moving component 2252 can be reset, so that the moving component 2252 always stops the other of the mounting member 22 and the cavity wall of the mounting cavity 120. In order to reduce the resistance between the moving component 2252 and the matching component 2253, the moving component 2252 can be arranged in a spherical structure.

[0213] During the process that the operator pushes the mounting member 22 to move from the second position to the first position, the second stopper 225 cooperates with the first matching inclined surface 22531, and under the guidance of the first matching inclined surface 22531, the second stopper 225 moves towards the limiting slot 2230, thereby avoiding the matching component 2253, so that the mounting member 22 can continue to move towards the first position. When the mounting member 22 moves to the first position, the second stopper 225 at least partially protrudes from the slot opening of the limiting slot 2230, and cooperates with the second matching inclined surface 22532, so that the matching component 2253 can have a certain blocking effect on the second stopper 225, preventing the mounting member 22 from moving reversely, so that the first filter assembly 10 and the mounting member 22 are in the combined state.

[0214] When the operator pulls the mounting member 22 from the first position to the second position, the second stopper 225 moves into the limiting slot 2230 under the guidance of the second matching inclined surface 22532, thereby avoiding the matching component 2253, so that the mounting member 22 can be moved towards the second position, even if the first filter assembly 10 and the mounting member 22 are in a movable state.

[0215] In the state that the filter device 100 is installed in place in the laundry treating apparatus, when it is needed to clean the filter device 100, the operator can pull the handle 224 of the second filter assembly 20 with a small force P1, thereby taking off the filter device 100, and during this process, it can be ensured that the second filter assembly 20 will not move relative to the first filter assembly 10, i.e. the second cleaning member 40 will not clean the second filter screen 21, due to the cooperation of the second stopper 225 and the matching component 2253. It can be understood that P1 needs to be smaller than the interaction force of the second stopper 225 and the matching component 2253.

[0216] After the filter device 100 is taken off from the laundry treating apparatus, the operator can pull the handle 224 of the second filter assembly 20 with a large force P2, so that the second filter assembly 20 overcomes the interaction force of the second stopper 225 and the matching component 2253, thereby moving the second filter assembly 20 relative to the first filter assembly 10, and cleaning the second filter screen 21 by using the second cleaning member 40. It can be understood that P2 needs to be greater than the interaction force of the second stopper 225 and the matching component 2253.

[0217] The laundry treating apparatus according to the embodiments of the present application is described below.

[0218] The laundry treating apparatus (not shown in the drawings) according to the embodiments of the present application comprises the filter device 100 described in the above embodiments. Since the filter device 100 according to the embodiments of the present application has the above technical effects, the laundry treating apparatus according to the embodiments of the present application also has the above technical effects, i.e. by using the above filter device 100, it is more convenient for the user to use the laundry treating apparatus, which is beneficial to improve the user experience.

[0219] In some embodiments, the laundry treating apparatus comprises a cabinet, a laundry treating assembly and an air duct assembly, the laundry treating assembly and the air duct assembly are both arranged in the cabinet, the laundry treating assembly has a laundry treating cavity, the air duct assembly has an air duct, the air duct communicates with the laundry treating cavity, the cabinet is provided with a mounting port, the mounting port communicates with the air duct, and the filter device 100 is adapted to be push-pullably arranged in the air duct through the mounting port.
