[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The principle and structure of the present invention will be described in detail below with reference to the attached drawings and embodiments.

[0033] In an air-conditioning unit, as an important air treatment device, the purification performance of a duct machine is directly related to the indoor air quality and user experience. With the increasing emphasis on a healthy environment, the requirements for the purification accessories of duct machines are also getting higher and higher. It is not only required to effectively filter pollutants such as particulate matter and bacteria in the air, but also to have convenient installation and maintenance characteristics to reduce operation and maintenance costs and improve work efficiency. In the design of traditional commercial duct machine purification accessories, sheet metal parts are mostly used in combination with a large number of screws for fixation. Although this structure ensures the stability of the accessories, it undoubtedly increases the complexity and time cost of on-site installation. Especially for the filter screen, a key component in the purification accessories, the installation and replacement process is cumbersome. It not only requires workers to have certain professional skills, but also easily leads to misoperations during the installation process, affecting the purification effect. In summary, while the existing commercial duct machine purification accessories provide an effective filtering function, they also face problems such as complex installation, difficult maintenance, and air volume loss.

[0034] As Figures 1-5 shown, the present utility model proposes an installation structure for a filter screen 2, which includes a filter screen frame 4 and a filter screen 2 disposed within the filter screen frame 4. The solution proposed by the present utility model is that at least one installation opening is provided on at least one side wall of the filter screen frame 4, and a limiting member 5 is provided outside the installation opening. A snap 6 corresponding to the installation opening is provided on the side surface of the filter screen 2. The snap 6 can pass through the corresponding installation opening and be stuck between the limiting member 5 and the side wall of the filter screen frame 4, so that the filter screen 2 is installed within the filter screen frame 4.

[0035] By providing an installation opening and a limiting member 5 on the filter screen frame 4 and cooperating with the corresponding snap 6 design on the filter screen 2, the quick installation and positioning of the filter screen 2 are realized, greatly simplifying the installation steps. When it is necessary to replace or clean the filter screen 2, the worker only needs to move the filter screen 2 so that the snap 6 is no longer stuck between the limiting member 5 and the side wall of the filter screen frame 4, and then the filter screen 2 can be replaced without a complex disassembly process, reducing the requirements for the professional skills of installation workers, and at the same time reducing the installation time and improving work efficiency.

[0036] At least one installation opening is provided on at least one side wall of the filter screen frame 4, and a limiting member 5 is provided outside the installation opening. The limiting member 5 is in the shape of a rectangular sheet with a convex middle part. The two ends of the limiting member 5 are respectively connected to the opposite sides of the installation opening, and the middle part protrudes from the outer surface of the filter screen frame 4. A clamping gap for clamping the snap 6 is formed between the two side edges of the limiting member 5 and the filter screen frame 4. The two gaps are respectively the first clamping gap and the second clamping gap. Specifically, the two ends of the limiting member 5 are respectively connected to the upper side edge and the lower side edge of the installation opening.

[0037] The clamping gaps (the first clamping gap and the second clamping gap) formed between the two side edges of the limiting member 5 and the filter screen frame 4 provide a clamping space for the snap button 6. This makes the installation and disassembly of the filter screen 2 simple and fast, without the need for complex tools or cumbersome steps, improving the maintenance efficiency.

[0038] As Figure 5 shown, at least one installation opening is provided on at least one side wall of the filter screen frame 4, and a limiting member 5 is provided outside the installation opening. A snap button 6 corresponding to the installation opening is provided on the side surface of the filter screen 2. The snap button 6 can pass through the corresponding installation opening and be clamped between the limiting member 5 and the side wall of the filter screen frame 4, so that the filter screen 2 is installed in the filter screen frame 4. The snap button 6 includes: a clamping portion 61 and a connecting portion 62. The clamping portion 61 is in the shape of an oval sheet. One end of the connecting portion 62 is connected to the middle position of the back surface of the clamping portion 61, and the other end is connected to the side wall of the filter screen 2. One end of the clamping portion 61 passes through the installation opening and is clamped in the first clamping gap, and the other end of the clamping portion 61 passes through the installation opening and is clamped in the second clamping gap.

[0039] The specific operation steps are as follows: First, place the left end of the filter screen 2 into the filter screen frame 4, then insert the left end of the clamping portion 61 of the snap button 6 into the first clamping gap, then lay the filter screen 2 flat so that the right end of the snap button 6 is also within the installation opening, and move the filter screen 2 to the right so that the right end of the clamping portion 61 of the snap button 6 extends into the second clamping gap, and then the filter screen 2 and the filter screen frame 4 can be fixed. When disassembling the filter screen 2, move the filter screen 2 to the left, lift the right end of the filter screen 2 and move the filter screen 2 to remove the filter screen 2. The installation and disassembly are simple and fast, without the need for complex tools or cumbersome steps.

[0040] The installation and disassembly of the filter screen 2 can be completed through simple clamping actions, without the need to use complex tools or perform cumbersome adjustments.

[0041] As Figures 1-5 shown, in a further embodiment, one end of the clamping portion 61 passes through the installation opening and is clamped in the first clamping gap, and the other end of the clamping portion 61 passes through the installation opening and is clamped in the second clamping gap. One end of the clamping portion 61 that is clamped into the second clamping gap and faces the filter screen 2 is provided with a convex point for clamping with the installation opening. A notch is provided at the position corresponding to the convex point of the installation opening. After one end of the clamping portion 61 without the convex point is clamped into the first clamping gap, move the filter screen 2 so that the end of the filter screen 2 with the convex point is clamped into the second clamping gap, that is, when the clamping portion 61 is clamped between the limiting member 5 and the side wall of the filter screen frame 4, the convex point is clamped at the notch. Through the clamping of the convex point and the notch, the connection strength and stability between the filter screen 2 and the filter screen frame 4 are increased, preventing the filter screen 2 from loosening or falling off during use.

[0042] The clamping portion 61 is in the shape of an oval sheet. One end of the connecting portion 62 is connected to the middle position of the back surface of the clamping portion 61, and the other end is connected to the side wall of the filter screen 2. Moreover, the clamping portion 61 is parallel to the side wall of the filter screen 2 to which it is installed. The parallel design makes the connection between the clamping portion 61 and the side wall of the filter screen 2 more stable, reducing the risk of deformation or damage caused by uneven stress.

[0043] One end of the connecting portion 62 is connected to the middle position of the back surface of the clamping portion 61, and the other end is connected to the side wall of the filter screen 2. The connecting portion 62 is in the shape of a sheet. One side of the connecting portion 62 is provided with an inclined surface that forms an angle less than 90° with the filter screen frame 4, and the filter screen frame 4 on one side of the installation opening is stuck at the angle between the connecting portion 62 and the filter screen frame 4.

[0044] The connecting portion 62 is designed to be in the shape of a sheet and has an inclined surface that forms an angle less than 90° with the filter screen frame 4, enabling the filter screen frame 4 to easily slide into or be stuck at the angle between the connecting portion 62 and the filter screen frame 4 during the installation process.

[0045] In a further embodiment, the limiting member 5 and the filter screen frame 4 are integrally formed. This improves the strength and rigidity of the overall structure, making the filter screen 2 more stable and reliable when facing external forces such as wind pressure and vibration.

[0046] In this embodiment, an installation opening is respectively provided on the side walls of the filter screen frame 4 on opposite sides, and a snap 6 corresponding to the installation opening is respectively provided on opposite sides of the filter screen 2. First, place the left end of the filter screen 2 into the filter screen frame 4, then insert the left end of the snap 6 of the clamping portion 61 into the first clamping gap, then lay the filter screen 2 flat so that the right ends of the snaps 6 on both sides are also within the installation opening, and move the filter screen 2 to the right so that the right end of the snap 6 of the clamping portion 61 extends into the second clamping gap, and the filter screen 2 and the filter screen frame 4 can be fixed. When disassembling the filter screen 2, move the filter screen 2 to the left, lift the right end of the filter screen 2 upward and move the filter screen 2 to remove the filter screen 2. The installation and disassembly become simple and fast, without the need for complex tools or cumbersome steps.

[0047] In another embodiment, an installation opening is provided on one side wall of the filter screen frame 4, and a hook-and-loop fastener sub-surface is provided on the other side wall opposite thereto. A snap 6 is provided on one side wall of the filter screen frame 4, and a hook-and-loop fastener mother-surface for sticking to the hook-and-loop fastener sub-surface is provided on the other side wall opposite thereto. One side of the filter screen is connected to the filter screen frame through a snap, and the other side is connected to the filter screen frame through a hook-and-loop fastener.

[0048] The snap 6 and the hook-and-loop fastener mother-and-sub surfaces provided on the side wall opposite to the installation opening enable the filter screen 2 to be easily disassembled from the frame when it needs to be cleaned or replaced. The snap 6 provides mechanical fixation, while the hook-and-loop fastener provides adhesion, and the combination of the two ensures the convenience and stability of disassembly.

[0049] In a further embodiment, a plurality of filters 2 are sequentially arranged on the filter frame 4 along the length direction.

[0050] In this embodiment, the cross-section of the filter is arranged in an elliptical shape, which increases the contact area between the return air and the filter. At the same time, when the return air passes through the filter, the wind passes through the cross-section of the filter. The streamlined design reduces wind resistance, while ensuring the filtering effect and reducing the loss of air volume passing through the filter.

[0051] The filter screen 2 is provided with a circle of plastic frame around it, and the scratch buckle 6 is arranged on the plastic frame.

[0052] The utility model also provides an air conditioning unit, including the filter screen 2 installation structure of the utility model.

[0053] A return air frame 1 is provided at the return air outlet of the air-conditioning unit. The return air frame 1 is provided with an outwardly bent folded edge for installing the filter 2 installation structure. The edge where the filter frame 4 is connected to the return air outlet is also provided with an outwardly bent folded edge to connect the folded edge at the return air outlet and the filter frame 4.

[0054] Compared with the prior art, the utility model proposes a filter 2 installation structure, wherein at least one installation opening is provided on the side wall of the filter frame 4, and a limiter 5 is provided at the opening, and a buckle 6 is provided on the side of the filter 2, and the buckle 6 is passed through the corresponding installation opening and clamped between the limiter 5 and the side wall of the filter frame 4, so that the filter 2 is fixed in the filter frame 4. When disassembling the filter 2, it is only necessary to move the filter 2 so that the buckle 6 is separated from the limiter 5 and the side wall of the filter frame 4 to complete the disassembly. There is no need for a complicated disassembly process, which reduces the requirements for the professional skills of the installation workers, and also reduces the installation time and improves the work efficiency.
