[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figures 1 to 7As shown, in a first aspect of this utility model embodiment, a filter unit is provided. The filter unit includes a filter body 1, which has a first filter surface 2 and a second filter surface 3 disposed opposite to each other along a first direction. The filter body 1 also has a first end face 4 and a second end face 5 disposed opposite to each other along a second direction. The first direction and the second direction are arranged at an angle. A first connecting component 8 is disposed on the first end face 4, and a second connecting component 9 is disposed on the second end face 5. The first connecting component 8 is used to cooperate with the second connecting component 9 on other filter units to realize the connection of two filter units. On the same filter body 1, the first connecting component 8 is located on the first end face 4 near the edge of the first filter surface 2, and the second connecting component 9 is located on the second end face 5 near the edge of the second filter surface 3.

[0040] Specifically, filter body 1 refers to a component with a certain volume. Filter body 1 can filter the air passing through it. The overall shape of filter body 1 is usually a plate-like structure with a certain thickness. Multiple filter bodies 1 can be connected in sequence to form an air conditioning filter. First filter surface 2 and second filter surface 3 refer to surface structures with a certain area. Both first filter surface 2 and second filter surface 3 can be planar or curved. First filter surface 2 and second filter surface 3 are generally the two largest plate surfaces on filter body 1. Air can enter filter body 1 from first filter surface 2 and exit from second filter surface 3, and vice versa. In this case, the first direction is usually the thickness direction of filter body 1. First end face 4 and second end face 5 both refer to surface structures with a certain area. First end face 4 and second end face 5 are generally planar structures. The angle between the second direction and the first direction is usually a right angle. The second direction can be the length or width direction of filter body 1.

[0041] The first connecting component 8 refers to a part or assembly that can connect two objects, and the second connecting component 9 also refers to a part or assembly that can connect two objects. The first connecting component 8 can be connected to the second connecting components 9 on other filter units by means of plugging, snapping, or fastener connection, etc. The connection between the two filter units can be a rigid connection or a hinged connection, etc.

[0042] The air conditioner filter provided in this embodiment of the utility model has a first filter surface 2 and a second filter surface 3 on the filter body 1, which are arranged opposite to each other along a first direction. The filter body 1 also has a first end face 4 and a second end face 5, which are arranged opposite to each other along a second direction. A first connecting component 8 is provided on the first end face 4, and a second connecting component 9 is provided on the second end face 5. The first connecting component 8 can cooperate with the second connecting component 9 on other filter units to achieve connection between two adjacent filter bodies 1. Meanwhile, on the same filter body 1, the first connecting component 8 is located on the first end face 4 near the edge of the first filter surface 2, and the second connecting component 9 is located on the second end face 5 near the edge of the second filter surface 3. Thus, the first connecting component 8 and the second connecting component 9 on the same filter body 1 are arranged diagonally. Compared with the air conditioner filter in the prior art, when the air conditioner filter needs to be folded, the first filter surface 2 and the second filter surface 3 of the filter body 1 can be fitted together. This makes the space occupied by multiple filter bodies 1 after folding smaller than the space occupied by rolling. It avoids the problem of inconvenience in disassembly and assembly of the air conditioner filter due to space constraints, and makes the maintenance of the air conditioner filter more convenient and faster.

[0043] It should be noted that, provided there is sufficient space, when the air conditioner filter needs to be disassembled and maintained, the air conditioner filter can be pulled directly out of the track without folding the filter body 1.

[0044] In one embodiment, see Figures 8 to 10 The first connecting component 8 includes a first limiting ring 81 and a first rotating shaft 82 spaced apart along a third direction. The third direction is set at an angle to both the first direction and the second direction. The second connecting component 9 includes a second limiting ring 91 and a second rotating shaft 92 spaced apart along a third direction. The end of the first rotating shaft 82 facing away from the first limiting ring 81 is a first insertion end 821, which is used to insert and cooperate with the second limiting ring 91 on other filter units. The end of the second rotating shaft 92 facing away from the second limiting ring 91 is a second insertion end 921, which is used to insert and cooperate with the first limiting ring 81 on other filter units.

[0045] Specifically, the first limiting ring 81 refers to a component with a certain volume. The first limiting ring 81 typically has a plug-in structure for mates with the second plug-in end 921. The plug-in structure can be a circular groove, a blind hole, or a through hole, etc. Similarly, the second limiting ring 91 refers to a component with a certain volume. The second limiting ring 91 typically also has a plug-in structure for mates with the first plug-in end 821. The plug-in structure can be a circular groove, a blind hole, or a through hole, etc. Both the first rotating shaft 82 and the second rotating shaft 92 refer to shaft structures with a certain length. The first rotating shaft 82 and the second rotating shaft 92 can be fixed to the filter body 1 by welding or adhesive.

[0046] In this embodiment, a first connecting assembly 8 is formed by a first limiting ring 81 and a first rotating shaft 82 spaced apart along a third direction, and a second limiting ring 91 and a second rotating shaft 92 spaced apart along a third direction. The end of the first rotating shaft 82 opposite to the first limiting ring 81 is a first insertion end 821, and the end of the second rotating shaft opposite to the second limiting ring 91 is a second insertion end 921. When connecting the filter body 1 to other filter units, the second rotating shaft 92 on the other filter unit can be placed between the first limiting ring 81 and the first rotating shaft 82. The first rotating shaft 82 on the filter body 1 will also be located between the second rotating shaft 92 and the second limiting ring 91 on the adjacent filter body 1. At this time, the first limiting ring 81, the second rotating shaft 92, and the second limiting ring 91 are all on the same straight line. Finally, the two filter bodies 1 are moved relative to each other in a third direction, so that the first insertion end 821 can be inserted into the insertion structure on the first limiting ring 81, and the second insertion end 921 can be inserted into the insertion structure of the second limiting ring 91. The first connecting component 8 and the second connecting component 9 adopt the above structure, which makes the connection between the two filter bodies 1 simpler and more convenient, and improves the assembly efficiency of the air conditioning filter.

[0047] In an optional embodiment, please refer to Figures 8 to 10 Both the first limiting ring 81 and the second limiting ring 91 include a ring body and a rotating hole penetrating the ring body. Specifically, the ring body refers to a component with a certain volume, which can be disc-shaped, block-shaped, or a combination of various shapes. The rotating hole refers to a hole structure with a certain diameter, which is usually a circular hole. In this embodiment, a rotating hole is provided on the ring body, penetrating the ring body. During the process of connecting and assembling the two filter bodies 1, the second insertion end 921 can be inserted into the rotating hole on the first limiting ring 81, and the first insertion end 821 can be inserted into the rotating hole on the second limiting ring 91.

[0048] In one embodiment, see Figure 1 , Figure 2 as well as Figures 8 to 10 The filter body 1 also has a third end face 6 and a fourth end face 7 arranged opposite each other along a third direction. A first limiting ring 81 is located on the first end face 4 near the edge of the third end face 6, a first rotating shaft 82 is located on the first end face 4 near the region of the fourth end face 7, a second limiting ring 91 is located on the second end face 5 near the edge of the third end face 6, and a second rotating shaft 92 is located on the second end face 5 near the region of the fourth end face 7. Specifically, both the third end face 6 and the fourth end face 7 refer to surface structures with a certain area, and they are typically planar structures. In this embodiment, with the first connecting component 8 located on the edge of the first end face 4 near the edge of the first filter surface 2, and the second connecting component 9 located on the edge of the second end face 5 near the edge of the second filter surface 3, the positions of the first limiting ring 81 located on the edge of the first end face 4 near the edge of the third end face 6, the first rotating shaft 82 located on the region of the first end face 4 near the fourth end face 7, the second limiting ring 91 located on the edge of the second end face 5 near the edge of the third end face 6, and the second rotating shaft 92 located on the region of the second end face 5 near the fourth end face 7 are matched. When assembling the filter body 1 with another filter body 1, simply rotating the other filter body 1 180° around an axis parallel to the second direction is sufficient to match the positions of the first limiting ring 81 and the first rotating shaft 82 on the first end face 4 of the filter body 1 with the positions of the second limiting ring 91 and the second rotating shaft 92 on the second end face 5 of the other filter body 1. This also ensures that the positions of the first limiting ring 81 and the first rotating shaft 82 on the first end face 4 of the other filter body 1 are matched with the positions of the second limiting ring 91 and the second rotating shaft 92 on the second end face 5 of one filter body 1. The assembly of the entire air conditioning filter can be achieved by producing only one type of filter body 1, which reduces production costs.

[0049] In one embodiment, see Figure 10 and Figure 11Along the third direction, the first insertion end 821 and the fourth end face 7 are flush with each other. The fourth end face 7 has a first clearance structure 84, which accommodates the second limiting ring 91 on other filter units. The second insertion end 921 is also flush with the fourth end face 7, and the fourth end face 7 has a second clearance structure 94, which accommodates the first limiting ring 81 on other filter units. Specifically, both the first clearance structure 84 and the second clearance structure 94 refer to accommodating structures with a certain accommodating hole space. The first clearance structure 84 and the second clearance structure 94 can be a groove structure or a hole structure, etc. In this embodiment, by aligning both the first insertion end 821 and the second insertion end 921 flush with the fourth end face 7, and by providing a first clearance structure 84 and a second clearance structure 94 on the fourth end face 7, when the first insertion end 821 is inserted into the rotating hole on the second limiting ring 91 on the adjacent filter body 1, the second limiting ring 91 is accommodated within the first clearance structure 84, and when the second insertion end 921 is inserted into the rotating hole on the first limiting ring 81 on the adjacent filter body 1, the first limiting ring 81 is accommodated within the second clearance structure 94. This allows the assembled air conditioner filter to have a flatter side surface, preventing protruding structures from affecting the sliding of the air conditioner filter during installation.

[0050] In one embodiment, see Figure 11 and Figure 12 The first clearance structure 84 includes a first clearance groove surrounding the first insertion end 821, and the shape of the first clearance groove matches the shape of the first limiting ring 81. The second clearance structure 94 includes a second clearance groove surrounding the second insertion end 921, and the shape of the second clearance groove matches the shape of the second limiting ring 91. Specifically, both the first clearance groove and the second clearance groove refer to groove structures with a certain depth. In this embodiment, by adopting the form of a first clearance groove for the first clearance structure 84 and a second clearance groove for the second clearance structure 94, the structure of the filter body 1 is simplified.

[0051] In one embodiment, see Figures 8 to 10A first guide structure 83 is provided on the first end face 4, located between the first limiting ring 81 and the first rotating shaft 82, for guiding the movement of the second rotating shaft 92 on other filter units. A second guide structure 93 is provided on the second end face 5, located between the second limiting ring 91 and the second rotating shaft 92, for guiding the first rotating shaft 82 on other filter units. Specifically, both the first guide structure 83 and the second guide structure 93 refer to structures or components used to guide the movement of objects. The first guide structure 83 and the second guide structure 93 can be guide grooves, or they can be formed by multiple components, such as a guide structure composed of two spaced-apart strip-shaped or plate-shaped structures. In this embodiment, by providing a first guide structure 83 between the first limiting ring 81 and the first rotating shaft 82, the sliding of the second rotating shaft 92 on other filter units can be guided when it is inserted into the rotating hole on the first limiting ring 81, making the mutual insertion of the second rotating shaft 92 and the first limiting ring 81 more convenient and accurate. Similarly, by providing a second guide structure 93 between the second limiting ring 91 and the second rotating shaft 92, the sliding of the first rotating shaft 82 on other filter units can be guided when it is inserted into the rotating hole on the second limiting ring 91, making the mutual insertion of the first rotating shaft 82 and the first limiting ring 81 more convenient and accurate, thereby improving the efficiency of assembling multiple filter bodies 1 together.

[0052] In one embodiment, see Figures 8 to 10 The first guide structure 83 includes a first guide groove disposed on the first end face 4 and extending in a third direction, and the second guide structure 93 includes a second guide groove disposed on the second end face 5 and also extending in a third direction. Specifically, both the first guide groove and the second guide groove refer to groove structures with a certain length. The cross-sectional shape of the first guide groove can match the outer wall shape of the second rotating shaft 92, and the cross-sectional shape of the second guide groove can match the outer wall shape of the first rotating shaft 82. In this embodiment, by using a first guide groove for the first guide structure 83 and a second guide groove for the second guide structure 93, the structure of the filter body 1 can be simplified, and the processing cost of the filter body 1 can be reduced.

[0053] In one embodiment, see Figures 8 to 10The filter body 1 includes a support frame 12 and a filter section 11. The support frame 12 is arranged around the periphery of the filter section 11 and is used to support the filter section 11. A first limiting ring 81 and a first rotating shaft 82 are both disposed on the support frame 12, as are a second limiting ring 91 and a second rotating shaft 92. Specifically, the filter section 11 refers to a component that removes impurities, odors, and harmful substances from the gas. The filter section 11 allows air to pass through and achieves purification or separation as the gas passes through. The filter section 11 can be made of materials such as synthetic fibers, activated carbon, glass fiber, and ceramics. The support frame 12 is a support component with a certain area, and an installation space for accommodating and installing the filter section 11 is provided inside the support frame 12. In this embodiment, by fitting a support frame 12 around the filter section 11 to form the filter body 1, and by placing the first limiting ring 81, the first rotating shaft 82, the second limiting ring 91 and the second rotating shaft 92 on the support frame 12, the overall structure of the filter body 1 can be made more robust and reliable.

[0054] In one embodiment, see Figures 8 to 10 Both the first limiting ring 81 and the second limiting ring 91 are integrally formed with the support frame 12, and both the first rotating shaft 82 and the second rotating shaft 92 are fixed to the support frame 12 by welding or gluing. In this embodiment, the first limiting ring 81 and the second limiting ring 91 can be manufactured simultaneously during the processing of the support frame 12 by punching or laser cutting, thereby making the installation and connection of the first limiting ring 81 and the second limiting ring 91 more secure. In addition, after the first rotating shaft 82 and the second rotating shaft 92 are processed, they can be fixed to the support frame 12 by welding or gluing, reducing the manufacturing cost of the filter body 1.

[0055] Secondly, please refer to Figures 1 to 7 The system includes at least two filter units as described above, with adjacent filter units connected by a first connecting component 8 and a second connecting component 9. Specifically, the connection between the first connecting component 8 and the second connecting component 9 is generally a rotatable connection. When the entire air conditioning filter needs to be folded, the first filter surface 2 of the filter body 1 can be fitted together with the second filter surface 3 of the filter body 1. This makes the space occupied by multiple folded filter bodies 1 smaller than that occupied by rolling, avoiding the inconvenience of disassembly and assembly caused by space constraints, and making the maintenance of the air conditioning filter more convenient and faster.

[0056] Secondly, please refer to Figure 13An air conditioner is provided, including an air conditioning filter 100 as described above, wherein the air conditioning filter 100 can be installed in a mounting rail 300 on the side of the evaporator 200. The beneficial effects of the second aspect described above can be found in the relevant description in the first aspect described above, and will not be repeated here.

[0057] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
