[0045] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same elements throughout the drawings. The embodiments described in the following exemplary embodiments do not represent all the technical ideas falling within the scope of the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0046] In the present disclosure, the directional terms "first direction, second direction" used without the contrary description refer to two intersecting directions, for example, which can be referred to as the horizontal direction and the vertical direction. Figure 3 ​​The positional adjectives such as "inner" and "outer" refer to the inner and outer of the specific structure profile, and the terms such as "first" and "second" are only used to distinguish one element from another element, and do not have sequential and important meanings, and the plurality of the present application refers to two or more and includes two.

[0047] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0048] Referring to Figures 1 to 7 The present disclosure provides a filter screen structure 100, which comprises a filter screen body 10, a first frame 1, a second frame 2 and an elastic clamping piece 3. The first frame 1 and the second frame 2 are connected to each other to install the filter screen body 10, and the elastic clamping piece 3 is arranged on the first frame 1. The elastic clamping piece 3 comprises a body part 31, a clamping part 32 and a pressing part 33. The clamping part 32 and the pressing part 33 are both connected to the body part 31. At least the body part 31 can be elastically deformed to make the clamping part 32 have a clamping position and an unlocking position. In the clamping position, the clamping part 32 can be used to clamp with an external component. In the unlocking position, the clamping part 32 can be used to unlock with the external component. The pressing part 33 is arranged close to the second frame 2 and can make the clamping part 32 switch from the clamping position to the unlocking position.

[0049] In the above technical solution, by arranging the elastic clamping piece 3, the operator can press the pressing part 33 to switch the clamping part 32 between the clamping position and the unlocking position, so as to realize the clamping installation and dismounting of the filter screen structure 100 with the external component, making the installation and dismounting of the filter screen structure 100 simple, without the need for additional tools or complex operation steps, and facilitating the operation of the operator.

[0050] In a specific use scenario, the filter screen structure 100 described above can be applied to an air duct machine, and the external component described above can be configured as a shell of the air duct machine.

[0051] In an embodiment, referring to Figures 1 to 3 The body part 31 can be elastically deformed at least along a first direction A and drive the clamping part 32 to move along the first direction A to switch between the clamping position and the unlocking position. The second frame 2 is formed with a pressing groove 20, and the pressing part 33 is pressingly arranged in the pressing groove 20 along the first direction A.

[0052] In this embodiment, firstly, since the body part 31 can be elastically deformed in the first direction A and directly drive the clamping part 32 to move in the same direction A to realize position switching, this design ensures the accuracy of operation. Users can achieve clamping or unlocking through explicit actions (such as pressing), reducing the possibility of misoperation. Secondly, the pressing part 33 is arranged in the pressing groove 20 formed by the second frame 2, so that users can intuitively perform the pressing operation, improving the user's operation experience. Moreover, the design of the pressing groove 20 cleverly utilizes the space of the second frame 2 to provide a mounting position for the pressing part 33, while not affecting the compactness of the overall structure. In addition, when the pressing part 33 is located in the pressing groove 20, it can only be pressed along the first direction A, and this restrictive movement mode prevents unintended unlocking caused by accidental touching, thereby enhancing the safety during use.

[0053] Optionally, as shown in Figure 3 and Figure 7 , the body part 31 comprises a U-shaped elastic sheet, the U-shaped elastic sheet comprises a first side sheet 311, a curved sheet 312, and a second side sheet 313; the first side sheet 311 and the second side sheet 313 are connected through the curved sheet 312, one end of the first side sheet 311 away from the curved sheet 312 is connected with the second frame 2, and one end of the second side sheet 313 away from the curved sheet 312 is connected with the pressing part 33; wherein the clamping part 32 is arranged on the side of the second side sheet 313 away from the first side sheet 311.

[0054] In this embodiment, firstly, the design of the U-shaped elastic sheet utilizes the elastic properties of the material itself, especially the radius formed at the curved sheet 312 can provide good resilience, when an external force is applied (such as pressing), the U-shaped elastic sheet can be deformed to store energy; when the external force is removed, it can quickly restore to its original state, ensuring that the clamping part 32 can smoothly switch between the clamping position and the unlocking position. Secondly, the design of the U-shaped elastic sheet limits the movement trajectory of the clamping part 32, ensuring that it can only move in the predetermined direction, avoiding the risk of accidental unlocking.

[0055] Optionally, as shown in Figure 3 and Figure 7 , the first side sheet 311 and the second side sheet 313 are arranged in the first direction A, and the first side sheet 311 and the second side sheet 313 extend in the second direction B; wherein the first direction A and the second direction B are arranged intersecting.

[0056] When the pressing part 33 is pressed down, the U-shaped elastic sheet mainly deforms in the first direction A, and since the first side sheet 311 and the second side sheet 313 extend in the second direction B, they can provide additional stiffness support to ensure that the deformation is mainly concentrated in the desired direction.

[0057] In one embodiment, as shown in Figure 3As shown, the first side piece 311 comprises a first inner side, and the second side piece 313 comprises a second inner side, the first inner side and the second inner side are oppositely arranged in the first direction A; wherein the distance L1 between the first inner side and the second inner side in the first direction A is between 4mm and 6mm. The distance is arranged to ensure that the U-shaped elastic piece has a certain elasticity, while also reducing the space occupied in the first direction A as much as possible, facilitating compact design. However, the specific size is not limited in the present disclosure.

[0058] In other embodiments, referring to Figure 3 As shown, the pressing part 33 comprises a pressing piece connected to the second side piece 313 and extending in the second direction B; the pressing piece comprises a first end away from the second side piece 313 in the second direction B, and the bending piece 312 comprises a second end away from the second side piece 313 in the second direction B; wherein the distance L2 between the first end and the second end is between 25mm and 32mm.

[0059] In this embodiment, the pressing piece extends in the second direction B, providing a larger pressing surface for the user, so that the user can more conveniently apply force with the fingers, improving the user experience. In addition, the design within this distance range enables the U-shaped elastic piece to effectively elastically deform after being pressed, without affecting its rebound performance due to too short or too long distance, and can reduce the risk of U-shaped elastic piece breaking as much as possible.

[0060] In addition, referring to Figure 7 As shown, the clamping part 32 can move in the first direction A by a distance L3 of between 1mm and 1.5mm, and only 1mm to 1.5mm of movement distance is required to complete the clamping and unlocking operation. This small displacement ensures the accuracy of the action, and the user can achieve the desired effect through slight action, reducing unnecessary force exertion. In addition, the smaller movement distance means that the clamping part 32 can complete the position switching in a short time, improving the response speed of the operation.

[0061] Optionally, referring to Figure 7 As shown, the clamping part 32 comprises a clamping block formed with an abutting surface 320 for abutting with an external member in the second direction B. The design of the abutting surface 320 provides a clear and stable contact point, ensuring that the clamping part 32 can accurately interface with the external member. This improves the accuracy of the clamping process and reduces the risk of installation problems or failure due to inaccurate positioning.

[0062] In another embodiment, referring to Figure 1 and Figure 3As shown, the first frame 1 includes a first frame body 11 and an outer rim plate 12 connected to the outer edge of the first frame body 11, and the outer rim plate 12 is formed with a relief groove 120; the first side piece 311 is connected to the first frame body 11 at the end away from the curved piece 312, and the second side piece 313 is connected to the pressing portion 33 by passing through the relief groove 120 at the end away from the curved piece 312.

[0063] In this embodiment, the design of the relief groove 120 effectively utilizes the space of the outer rim plate 12, providing a path for the second side piece 313 to pass through and connect to the pressing portion 33. This not only saves space, but also makes the entire device more compact, suitable for applications with limited volume.

[0064] In addition, referring to Figure 3 As shown, the body portion 31 further includes a reinforcing rib 314, at least part of the inner side of the curved piece 312 is provided with the reinforcing rib 314. By providing the reinforcing rib 314, the U-shaped elastic piece is prevented from breaking, and the strength of the structure is improved.

[0065] For example, referring to Figure 3 As shown, the reinforcing rib 314 includes a first reinforcing section 3141, a second reinforcing section 3142, and a third reinforcing section 3143, the first reinforcing section 3141 and the third reinforcing section 3143 are connected by the second reinforcing section 3142. The first reinforcing section 3141 is protrudingly arranged on the inner wall of part of the first side piece 311, the third reinforcing section 3143 is protrudingly arranged on the inner wall of part of the second side piece 313, and the second reinforcing section 3142 is protrudingly arranged on the inner wall of the curved piece 312.

[0066] In this embodiment, the presence of each reinforcing section can effectively disperse the stress applied to the U-shaped elastic piece, preventing excessive deformation or breaking caused by local stress concentration. In particular, the second reinforcing section 3142 is located on the curved piece 312, which can provide additional support during bending, making the elastic deformation more uniform and controllable.

[0067] In addition, referring to Figure 3 As shown, in the direction away from the second reinforcing section 3142, the size of the first reinforcing section 3141 protruding from the inner wall of the first side piece 311 gradually decreases; and / or, in the direction away from the second reinforcing section 3142, the size of the third reinforcing section 3143 protruding from the inner wall of the second side piece 313 gradually decreases.

[0068] In this embodiment, the gradually changing thickness design makes the stress more evenly distributed between different parts of the U-shaped elastic piece, especially providing more support near the second reinforcing section 3142, while gradually reducing the material thickness in the distant part. This helps to prevent breaking or deformation caused by stress concentration, improving the durability of the overall structure.

[0069] In addition, the outer edge plate 12 can be provided with a fastening hole, and a fastener can be arranged through the fastening hole to fix the filter screen structure 100 to an external component.

[0070] Referring to Figure 6 and Figure 7 , the first frame 1 is provided with an elastic clamping piece 3 on one side along the first direction A, and a clamping groove 13 is formed on the other side along the first direction A, which is used for clamping with an external component. In the specific installation process, the clamping groove 13 can be clamped with the external component first, and then the elastic clamping piece 3 is clamped with the external component, so as to realize the positioning of the filter screen structure 100, and facilitate the subsequent fastening and installation.

[0071] Optionally, the elastic clamping piece 3 is integrally formed on the first frame 1, which ensures the seamless connection between the elastic clamping piece 3 and the first frame 1, eliminates the connection points that may exist in the traditional assembly process, and improves the strength of the structure.

[0072] Referring to Figures 4 to 7 , the disclosure also provides an air conditioning device, which comprises a device shell 200 and the filter screen structure 100 described above; the device shell 200 is formed with at least one air inlet 300, and the filter screen structure 100 is detachably arranged at the air inlet 300 through the elastic clamping piece 3.

[0073] For example, the air conditioning device can be constructed as a ducted type air conditioner, and the air inlet 300 can be provided with two.

[0074] Optionally, referring to Figure 7 , the edge of the air inlet 300 is formed with an inwardly bent flange 3001, and the elastic clamping piece 3 is used for clamping with the flange 3001.
