[0002] In air handling equipment such as air conditioners and air purifiers, filter components are often used to filter dust and other impurities in the air to ensure that clean airflow is output from the air outlet of the air handling equipment.

[0003] When the filter assembly filters impurities in the air, dust and other impurities will directly adhere to the filter assembly. During use, the filter assembly is easily affected by the accumulation of dust and dirt, which will affect the filtering effect and the airflow efficiency of the air handling equipment, thereby affecting the operating effect of the air handling equipment.

[0004] Traditional air handling equipment does not have a self-cleaning mechanism for the filter, and the filter needs to be replaced and cleaned manually on a regular basis, which is labor-intensive and has high maintenance costs.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0056] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0057] In order to solve the technical problems of complex structure, high cost and large space occupancy of the self-cleaning filter assembly in the prior art, the present application provides a self-cleaning filter assembly, an air outlet structure and an air treatment device. The self-cleaning filter assembly arranges a first filter assembly 1 and a second filter assembly 2 relatively to each other, and the first filter assembly 1 is provided with a plurality of first protrusion structures 11 extending toward the second filter assembly 2, which can be used to abut against the second filter assembly 2. When the driving module drives the first filter assembly 1 and the second filter assembly 2 to move relative to each other, the relative friction between the first filter assembly 1 and the second filter assembly 2 is achieved through the first protrusion structure 11, so that the dust and other impurities adhered to the first filter assembly 1 and the second filter assembly 2 can fall off under the action of friction and vibration, thereby realizing automatic cleaning of the first filter assembly 1 and the second filter assembly 2. The size of the first protrusion structure 11 can be set according to the original spacing between the first filter assembly 1 and the second filter assembly 2, which will not lead to an increase in the space occupancy rate. It has the effects of simple structure, easy implementation and low space occupancy rate.

[0058] See also Figures 1 to 13 In a first aspect, the embodiment of the present application provides a self-cleaning filter assembly, including a first filter assembly 1, a second filter assembly 2 and a drive module; the first filter assembly 1 and the second filter assembly 2 are arranged relative to each other, and can achieve multi-stage filtration of the airflow, thereby improving the filtration effect, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown.

[0059] The first filter assembly 1 is provided with a plurality of first protruding structures 11, and the first protruding structures 11 are extended toward the second filter assembly 2 and are used to abut against the second filter assembly 2, thereby achieving partial contact between the first filter assembly 1 and the second filter assembly 2. Figure 1 and Figure 2 shown.

[0060] The driving module is connected to the first filter assembly 1 and / or the second filter assembly 2, and can drive the first filter assembly 1 and / or the second filter assembly 2 to move, so as to realize the relative movement of the first filter assembly 1 and the second filter assembly 2, so that the plurality of first protrusion structures 11 and the second filter assembly 2 are subjected to relative friction, and impurities on the second filter assembly 2 can be removed by the first protrusion structures 11; the first filter assembly 1 will also vibrate accordingly, so that the dust on the first filter assembly 1 can fall off under the action of vibration, thereby realizing automatic cleaning of the first filter assembly 1 and the second filter assembly 2.

[0061] It should be noted that the size of the first protruding structure 11 can be set according to the original spacing between the first filter assembly 1 and the second filter assembly 2, and the space occupancy rate of the self-cleaning filter assembly will not be increased due to the setting of the first protruding structure 11. And the relative friction and vibration between the first filter assembly 1 and the second filter assembly 2 are achieved through the first protruding structure 11, so as to achieve the cleaning of dust and impurities on the filter assembly (i.e., the first filter assembly 1 and the second filter assembly 2), which has the advantages of simple structure and easy implementation, and can effectively reduce the production cost of the self-cleaning filter assembly.

[0062] It should be noted that the driving module can be connected to one of the first filter assembly 1 and the second filter assembly 2 to achieve relative movement between the first filter assembly 1 and the second filter assembly 2 (i.e., between the first protrusion structure 11 and the second filter assembly 2), and can also be connected to the first filter assembly 1 and the second filter assembly 2 at the same time to drive the first filter assembly 1 and the second filter assembly 2 to move in opposite directions or move in the same direction with differential speed (i.e., the movement speed of one filter assembly is greater than the movement speed of the other filter assembly) to achieve relative movement between the first filter assembly 1 and the second filter assembly 2, both of which can achieve the purpose of the present application.

[0063] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Fig.10 A plurality of first protrusion structures 11 are evenly arranged on the first filter assembly 1, which can provide a uniform friction cleaning effect on the second filter assembly 2. At the same time, each area of ​​the first filter assembly 1 can also produce uniform vibration, thereby ensuring the self-cleaning effect of the first filter assembly 1 and the second filter assembly 2.

[0064] In some embodiments of this application, please refer to Figure 2 , Figure 7 and Figure 8 The first protrusion structure 11 is made of elastic material, which can prevent the first protrusion structure 11 from causing wear on the surface of the second filter assembly 2 when the first protrusion structure 11 rubs and cleans the second filter assembly 2. The first protrusion structure 11 has elastic deformation ability and can perform gap compensation, so that the multiple first protrusion structures 11 can always keep in contact with the second filter assembly 2 during use, thereby preventing the self-cleaning filter assembly from failing due to wear of the first protrusion structure 11, and can increase the service life of the self-cleaning filter assembly.

[0065] In the above embodiment, the first filter assembly 1 achieves dust removal and cleaning only by its own vibration, which may cause some stubborn dirt to be difficult to remove.

[0066] In order to solve the above problems, in some embodiments of the present application, a plurality of second protrusion structures 21 are provided on the second filter assembly 2, and the second protrusion structure 21 extends toward the first filter assembly 1 and is used to abut against the first filter assembly 1. When the first filter assembly 1 and the second filter assembly 2 move relative to each other, the first filter assembly 1 can be frictionally cleaned by the second protrusion structure 21, and the second filter assembly 2 can be frictionally cleaned by the first protrusion structure 11. At the same time, when the first protrusion structure 11 collides with the second protrusion structure 21 relative to each other, the first filter assembly 1 and the second filter assembly 2 will cause greater vibration, which can further enhance the cleaning effect of the self-cleaning filter assembly.

[0067] In some embodiments of this application, please refer to Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The multiple first protrusion structures 11 and the multiple second protrusion structures 21 are arranged alternately, which is conducive to reducing the relative distance between the first filter assembly 1 and the second filter assembly 2, and avoiding increasing the overall installation space of the filter assembly when the first protrusion structures 11 and the second protrusion structures 21 are arranged at the same time. In addition, the multiple first protrusion structures 11 and the multiple second protrusion structures 21 are arranged alternately, which can increase the relative friction between the first filter assembly 1 and the second filter assembly 2, which is conducive to achieving strong cleaning of impurities on the first filter assembly 1 and the second filter assembly 2.

[0068] In some embodiments of the present application, the second protrusion structure 21 and the first protrusion structure 11 are made of the same material. When the first protrusion structure 11 and the second protrusion structure 21 abut against each other, the first protrusion structure 11 and the second protrusion structure 21 can be separated after abutment by elastic deformation driven by the driving module, such as Figure 4 , Figure 7 and Figure 8 shown.

[0069] In the above embodiments, the first protrusion structure 11 and the second protrusion structure 21 can be columnar protrusions or brush heads, or other protrusion components with rough friction surfaces. As long as relative friction cleaning between the first filter assembly 1 and the second filter assembly 2 can be achieved, the purpose of the present application can be achieved.

[0070] In some embodiments of this application, please refer to Figure 3 , the first filter assembly 1 includes a first filter element 12, and the second filter assembly 2 includes a second filter element 22. The filtering accuracy of the second filter element 22 is greater than the filtering accuracy of the first filter element 12, that is, the mesh size of the second filter element 22 is smaller than the mesh size of the first filter element 12. The air can be roughly filtered through the first filter element 12 first, and then finely filtered through the second filter element 22, thereby realizing a graded filtering design. In addition, the first filter assembly 1 can block larger impurities on the outside of the self-cleaning filter assembly, and only a small amount of small impurities will enter between the first filter assembly 1 and the second filter assembly 2, which can reduce the cleaning burden of the self-cleaning filter assembly.

[0071] In some embodiments of this application, please refer to Figure 7 and Fig.10 The first filter assembly 1 further includes a first filter frame 13, which is integrally connected to the first filter element 12 and can be used to fix the first filter element 12 to prevent the flexible first filter element 12 from curling arbitrarily and affecting the filtering effect of the first filter element 12. The first filter frame 13 and the first protruding structure 11 can be an integrated structure, thereby improving the production efficiency of the first filter assembly 1 and reducing the manufacturing difficulty of the first filter assembly 1.

[0072] In some embodiments of this application, please refer to Figure 7 and Figure 8 The second filter assembly 2 further includes a second filter frame 23, which is connected to the second filter element 22 as a whole, and can be used to fix the second filter element 22, so as to prevent the flexible second filter element 22 from curling arbitrarily and affecting the filtering effect of the second filter element 22. The second filter frame 23 and the second protrusion structure 21 can be an integrated structure, thereby improving the production efficiency of the second filter assembly 2 and reducing the manufacturing difficulty of the second filter assembly 2.

[0073] In some embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8The driving module includes a first driving component 3 and a second driving component 4. The first driving component 3 is connected to the first filter component 1 and is used to drive the first filter component 1 to move. The second driving component 4 is connected to the second filter component 2 and is used to drive the second filter component 2 to move. The relative speed and relative friction strength between the first filter component 1 and the second filter component 2 can be automatically controlled by controlling the first driving component 3 and the second driving component 4.

[0074] It should be noted that the first drive component 3 and the second drive component 4 can drive the first filter component 1 and the second filter component 2 to move in opposite directions, or drive the first filter component 1 and the second filter component 2 to move in the same direction with differential speed (that is, the moving speed of the first filter component 1 is greater than the moving speed of the second filter component 2, or the moving speed of the second filter component 2 is greater than the moving speed of the first filter component 1), both of which can achieve the purpose of the present application.

[0075] It should be noted that the first drive component 3 and the second drive component 4 can be linear motion actuator components, such as hydraulic cylinders, air cylinders or connecting rod components, etc., which can achieve traction or pushing of the first filter component 1 and the second filter component 2, and are suitable for use in occasions where the first filter component 1 and the second filter component 2 are rigid filter components that are not easily deformed.

[0076] The first drive assembly 3 and the second drive assembly 4 can also be drive assemblies including rotating drive parts, and the relative movement between the first filter assembly 1 and the second filter assembly 2 can be achieved by rolling up the first filter assembly 1 or the second filter assembly 2. It is suitable for use in occasions where the first filter assembly 1 and the second filter assembly 2 are flexible filter assemblies with deformation ability, and can achieve the purpose of this application.

[0077] However, when the first filter assembly 1 and the second filter assembly 2 are driven to move relative to each other by a linear motion actuator, since the linear motion actuator itself has a certain length, the layout space dimension of the self-cleaning filter assembly in the length direction of the filter assembly will be larger, which will affect the overall size and space occupancy rate of the air outlet structure and the air treatment equipment.

[0078] In order to solve the above problems, in some preferred embodiments of the present application, please refer to Figure 3 and Figure 4 The first drive assembly 3 and the second drive assembly 4 have the same structure and both include a reel and a rotating drive member for reeling in the first filter assembly 1 or the second filter assembly 2, thereby reducing the overall size of the self-cleaning filter assembly in the length direction of the filter assembly while achieving relative movement between the first filter assembly 1 and the second filter assembly 2, which is beneficial to reducing the installation space required for the self-cleaning filter assembly on the air outlet structure and / or air handling equipment.

[0079] In some embodiments of this application, please refer to Figure 3 , Fig. 9 and Fig.10 The first filter frame 13 and the second filter frame 23 are both long strip structures, and the length direction of the first filter frame 13 and the second filter frame 23 is parallel to the axis direction of the reel, so that the first filter assembly 1 and the second filter assembly 2 have the ability to deform in the length direction. This can avoid the first filter frame 13 and the second filter frame 23 from interfering with the winding of the first filter assembly 1 and the second filter assembly 2, and can also keep the first filter assembly 1 and the second filter assembly 2 flat in the height direction, respectively realizing the fixing effect of the first filter frame 13 on the first filter assembly 1 and the second filter frame 23 on the second filter assembly 2.

[0080] In some embodiments of this application, please refer to Figure 3 and Figure 4 The first tensioning assembly 5 and the first driving assembly 3 are respectively connected to the two ends of the first filter assembly 1. The first driving assembly 3 is used to realize the reeling and unreeling of the first filter assembly 1. The first tensioning assembly 5 is used to keep the first filter assembly 1 in a taut state during the reeling and unreeling process, so as to avoid wrinkles in the first filter assembly 1 during the movement process. The second tensioning assembly 6 and the second driving assembly 4 are respectively connected to the two ends of the second filter assembly 2. The second driving assembly 4 is used to realize the reeling and unreeling of the second filter assembly 2. The second tensioning assembly 6 is used to keep the second filter assembly 2 in a taut state during the reeling and unreeling process, so as to avoid wrinkles in the second filter assembly 2 during the movement process, so that the first protruding structure 11 can maintain uniform contact and mutual friction with the second filter assembly 2, and the second protruding structure 21 can maintain uniform contact and mutual friction with the first filter assembly 1, thereby ensuring the movement reliability of the self-cleaning filter assembly.

[0081] In some embodiments of this application, please refer to Figure 3 and Figure 4 The first tensioning assembly 5 includes a first rope body 51 and a first winding box 52. The first rope body 51 is connected between the first filter assembly 1 and the first winding box 52. The first filter assembly 1 can be tensioned by elastically contracting the first rope body 51 or by winding and unwinding the first rope body 51 by the first winding assembly in the first winding box 52, thereby achieving the purpose of the present application.

[0082] In some embodiments of this application, please refer to Figure 3 and Figure 4The second tensioning assembly 6 includes a second rope body 61 and a second winding box 62. The second rope body 61 is connected between the second filter assembly 2 and the second winding box 62. The second filter assembly 2 can be tensioned by elastically contracting the second rope body 61 or by winding and unwinding the second rope body 61 by the second winding assembly in the second winding box, thereby achieving the purpose of the present application.

[0083] In some embodiments of this application, please refer to Figure 3 The first filter assembly 1 is provided with a first tensioning assembly 5 on both upper and lower sides, which can be used to achieve uniform tensioning of the first filter assembly 1. The second filter assembly 2 is provided with a second tensioning assembly 6 on both upper and lower sides, which can be used to achieve uniform tensioning of the second filter assembly 2.

[0084] In the above embodiment, the first drive assembly 3 and the second drive assembly 4 can be arranged at the same end of the self-cleaning filter assembly, and the first tensioning assembly 5 and the second tensioning assembly 6 can be arranged at the other end of the self-cleaning filter assembly. At this time, the first filter assembly 1 and the second filter assembly 2 move in the same direction at a differential speed. The first drive assembly 3 and the second drive assembly 4 can also be arranged at the two ends of the self-cleaning filter assembly, respectively, and correspondingly, the first tensioning assembly 5 and the second tensioning assembly 6 are also arranged at the two ends of the self-cleaning filter assembly. Figure 3 and Figure 4 As shown, at this time, the first filter assembly 1 and the second filter assembly 2 are in reverse relative motion, and both can achieve the purpose of the present application.

[0085] However, when the first drive assembly 3 and the second drive assembly 4 are arranged at the same end of the self-cleaning filter assembly, in order to avoid interference between the first reel 31 and the second reel 41, a certain preset distance needs to be set between the first drive assembly 3 and the second drive assembly 4, which will cause the thickness of the self-cleaning filter assembly to be larger (i.e., the size in the relative directions of the first filter assembly 1 and the second filter assembly 2), and further increase the space occupancy rate of the self-cleaning filter assembly in the air outlet structure and / or the air treatment equipment.

[0086] In order to avoid the above problems, in some preferred embodiments of the present application, please refer to Figure 3 and Figure 4 The first drive assembly 3 and the second drive assembly 4 are respectively arranged at the two ends of the self-cleaning filter assembly, and the first tensioning assembly 5 and the second tensioning assembly 6 are also respectively arranged at the two ends of the self-cleaning filter assembly, which can not only avoid the mutual interference between the first reel 31 and the second reel 41 due to the close distance, but also effectively reduce the thickness size and space occupancy rate of the self-cleaning filter assembly.

[0087] Specifically, the first rotating drive member 32 drives the first reel 31 to rotate in the positive direction, so as to retract the first filter assembly 1, so that the first filter assembly 1 is directed toward Figure 4The second rotating drive member 42 drives the second reel 41 to rotate in the positive direction, so that the second filter assembly 2 is retracted, and the second filter assembly 2 is moved toward Figure 4 The first rotating drive member 32 drives the first reel 31 to rotate in the opposite direction, so as to unwind the first filter assembly 1, so that the first filter assembly 1 is directed toward Figure 4 The second rotating drive member 42 drives the second reel 41 to rotate in the opposite direction, so as to unwind the second filter assembly 2, so that the second filter assembly 2 is directed toward Figure 4 thereby achieving relative friction between the first filter assembly 1 and the second filter assembly 2.
