[0037] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0039] In the related art, the fixing method of the filter screen of the air conditioning equipment is greatly restricted by its installation position, and its installation and disassembly processes are relatively complex, which will not only affect the maintenance efficiency of the air conditioning equipment, but also may cause damage to the filter screen.

[0040] Reference Figure 1 As shown, in some embodiments of the filtering device provided by the present utility model, the filtering device includes a filter screen 1 and a mounting frame 2. The mounting frame 2 is provided with two mounting grooves 21 arranged at intervals. An installation space 201 is formed between the two mounting grooves 21. The filter screen 1 is installed in the installation space 201, and both ends of the filter screen 1 are respectively inserted into the interiors of the two mounting grooves 21. Notches 213 are provided in the extending directions of the two mounting grooves 21, so that the filter screen 1 can be inserted into or withdrawn from the installation space 201 through the notches 213.

[0041] The installation of both ends of the filter screen 1 is achieved through the two mounting grooves 21, providing sufficient support and ensuring the installation stability of the filter screen 1 in the installation space 201. Moreover, the filter screen 1 can slide within the mounting groove 21, so that the position of the filter screen 1 in the installation space 201 can be adjusted conveniently.

[0042] By providing the notches 213 on the mounting grooves 21, the filter screen 1 can be inserted into or withdrawn from the installation space 201 through the notches 213, without being restricted by the space at both ends of the mounting groove 21. This not only effectively improves the installation and disassembly efficiency of the filter screen 1, but also enables the filtering device of the present application to be conveniently applied to air conditioning equipment with different specifications and installation positions, greatly improving its versatility and also improving the maintenance efficiency of the air conditioning equipment.

[0043] The air conditioning equipment mentioned in the present application is not limited to one type. For example, it can be a central air conditioning unit room air conditioner, an air-cooled / water-cooled unit, etc. The filtering device of the present application can be applied to the air inlet, air outlet, return air outlet and other positions of various different air conditioning equipment for filtering the air flow.

[0044] In some specific embodiments, the filtering device of the present application can be installed at the return air outlet position of a duct machine.

[0045] Among them, the setting position of the notch 213 can be selected based on the specification size of the filter screen 1 or the installation position of the filter screen 1 in the extending direction of the installation groove 21. For example, it can be set in the middle of the length direction of the installation groove 21, or at a position close to both ends of the installation groove 21, etc., so as to adapt to the installation and removal requirements of different filter screens 1.

[0046] For example, in some feasible embodiments, in the extending direction of the installation groove 21, the lengths of the portions of the installation groove 21 on both sides of the notch 213 are equal.

[0047] In addition, the specification size of the notch 213 itself can also be set according to the actual situation.

[0048] In some embodiments, in the extending direction of the installation groove 21, the length of the notch 213 is 1 / 4 to 1 / 2 of the total length of the installation groove 21.

[0049] Specifically, the length of the notch 213 can be set to 1 / 3 of the total length of the installation groove 21.

[0050] In other feasible solutions, the relationship between the length of the notch 213 and the total length of the installation groove 21 can be appropriately adjusted, as long as the installation stability of the filter screen 1 is ensured, and it is also convenient for the filter screen 1 to be inserted and removed without being damaged.

[0051] In order to adapt to more different working conditions, more positions for inserting and removing the filter screen 1 can be set on the installation groove 21. For example, a plurality of notches 213 can be set along the extending direction of the installation groove 21.

[0052] In some embodiments, both ends of the two installation grooves 21 have openings, so that the filter screen 1 is inserted into or withdrawn from the installation space 201 through the openings.

[0053] By providing openings at both ends of the installation groove 21, the filter screen 1 can be disassembled and assembled through both ends of the installation groove 21.

[0054] Then, through the setting of the notch 213 and the openings on the installation groove 21, the filter screen 1 can not only be withdrawn or installed through the middle of the installation groove 21, but also be withdrawn or installed through the ends of the installation groove 21. Such a setting greatly improves the flexibility of the installation and removal of the filter screen 1.

[0055] Especially in embodiments where there are multiple filter screens 1, the diverse setting of the installation and removal positions can effectively improve the maintenance efficiency of the multiple filter screens 1.

[0056] Reference Figure 4 As shown, in some embodiments, the filtering device includes more than two filter screens 1, and the more than two filter screens 1 are arranged along the extending direction of the installation groove 21.

[0057] The number of the filter screens 1 can be set according to the specifications and dimensions of the filtering device of the present application, or can be set according to the model specifications of the air-conditioning equipment to which the filtering device is applied. Specifically, two, three, four or more filter screens 1 can be provided. Correspondingly, more corresponding notches 213 can also be provided in the extending direction of the installation groove 21 to facilitate the installation and removal of multiple filter screens 1.

[0058] When it is necessary to clean or replace the filter screen 1, if other components are installed at both ends of the installation groove 21, or are blocked by external objects, reference can be made to Figure 1 and Figure 3 As shown, the filter screen 1 is drawn out or inserted into the installation space 201 through the notch 213 provided at the middle position of the installation groove 21. Or, when the middle area of the installation groove 21 is blocked and the spaces at both ends of the installation groove 21 are sufficient, reference can be made to Figures 9 - 11 As shown, the filter screen 1 is drawn out or inserted into the installation space 201 through the openings at both ends of the installation groove 21.

[0059] Such installation and removal methods can effectively reduce the influence of external environmental factors on the maintenance process of the filter screen 1. Especially in application scenarios where the filter screen 1 needs to be frequently replaced, the above design of the structure of the installation groove 21 significantly improves the maintenance efficiency of the filter screen 1.

[0060] In some embodiments, the two installation grooves 21 are symmetrically arranged about a preset center line, and the notches 213 on the two installation grooves 21 are symmetrically arranged about the preset center line.

[0061] Here, the preset center line can be the center line located on the symmetry plane of the installation frame 2 or the filter screen 1. The symmetrical arrangement enables the positions of the installation groove 21 and the notch 213 to be aligned, further simplifying the installation and removal process of the filter screen 1.

[0062] In some embodiments, the filter screen 1 is an elastic filter screen so that the filter screen 1 can undergo a certain deformation without being damaged during the process of being drawn out or inserted into the installation space 201 through the notch 213 of the installation groove 21.

[0063] In some embodiments, the filter screen 1 is a PET filter screen or a PP filter screen. Or, different parts of the filter screen 1 can be made of different materials.

[0064] In some embodiments, the installation frame 2 includes an installation frame 22 and two first limiting portions. The two first limiting portions are both connected to the same side of the installation frame 22, and the first limiting portions and the installation frame 22 together enclose the installation groove 21.

[0065] The installation frame 22 serves as the main frame and provides support for the overall structure. By connecting the installation frame 22 to the main body of the air-conditioning equipment, the filtering device can be integrally installed on the air-conditioning equipment.

[0066] The first limiting part plays a limiting role, which can prevent the filter screen 1 from shifting or misaligning during the installation process, thereby ensuring the working reliability of the filtering device of the present application.

[0067] By arranging the two first limiting parts on the same side of the mounting frame 22 (for example, on the same side in the thickness direction), the installation space 201 between the installation grooves 21 can be formed on one side of the mounting frame 22. Specifically, when the installation space 201 is formed on one side of the mounting frame 22, when the filtering device is installed on the air-conditioning equipment, the side with the installation space 201 can be installed outward. Thus, if it is necessary to adjust the position of the filter screen 1 or perform maintenance on the filter screen 1, this operation process will not be affected by other components inside the air-conditioning equipment; and, arranging the two first limiting parts on the same side of the mounting frame 22 can also make this operation process more intuitive and convenient, thereby improving the installation and maintenance efficiency of the filter screen 1.

[0068] Reference Figure 1 and Figure 3 As shown in the figure, in some embodiments, the notch 213 of the installation groove 21 is arranged on the side of the first limiting part away from the mounting frame 22, which can make the installation and disassembly process of the filter screen 1 more intuitive and convenient and will not be hindered by the mounting frame 22. And in the case of installing the side with the installation space 201 outward toward the air-conditioning equipment as described above, arranging the notch 213 on the side of the first limiting part away from the mounting frame 22 is also arranging it on the outside of the air-conditioning equipment, thereby further improving the installation and maintenance efficiency of the filter screen 1.

[0069] In the embodiments of the present application, there are various choices for the specific structures of the mounting frame 22 and the first limiting part.

[0070] For reference, the mounting frame 22 can be set to have a frame structure (such as a U-shaped frame or a rectangular frame), wherein the hollow part of the frame structure is used to realize the flow of air. Or, the mounting frame 22 can also be set to have a mesh structure, a grid structure, etc., to improve the overall structural stiffness of the mounting frame 22 while ensuring that air can pass through.

[0071] For reference, the first limiting part can be set to have a bent structure (such as an L shape or a T shape) and be connected to one side of the mounting frame 22 to enclose a groove-shaped space for limiting the filter screen 1 together with the side surface of the mounting frame 22.

[0072] In addition, there are also various choices for the connection method between the mounting frame 22 and the first limiting part, such as welding, screw connection, 3D printing connection, etc.

[0073] Alternatively, in some embodiments, the first limiting portion and the mounting frame 22 are of an integrally formed structure. For example, sheet metal processing can be used to form the mounting frame 22 and the first limiting portion through processing steps such as blanking and bending, which has the characteristics of simple process and stable connection.

[0074] Reference Figure 2 As shown, in some embodiments, the first limiting portion includes a connecting plate 211 and a first side plate 212. The connecting plate 211 is connected between the mounting frame 22 and the first side plate 212, and a notch 213 is provided on the first side plate 212.

[0075] The first side plate 212 and the connecting plate 211 jointly act to provide the filter screen 1 with limiting and supporting effects in two directions, preventing the filter screen 1 from loosening due to the impact of air flow during use.

[0076] Specifically, the first side plate 212 and the connecting plate 211 can be set to be angled, especially perpendicular, to jointly define the internal space of the installation groove 21 with the side surface of the mounting frame 22.

[0077] Reference Figure 2 As shown, in some embodiments, the mounting frame 22 includes a frame body 221 and a second side plate 222. The side edges of the frame body 221 are respectively connected to the connecting plate 211 and the second side plate 222, and the second side plate 222 is disposed opposite to the first side plate 212.

[0078] The second side plate 222 and the first side plate 212 respectively form two side walls of the installation groove 21, and the connecting plate 211 forms the bottom wall of the installation groove 21, thereby providing the filter screen 1 with limiting and supporting in three directions and ensuring its installation stability in the installation space 201.

[0079] Specifically, the frame body 221 can be a rectangular frame, which plays an overall supporting role. The mounting frame 22 includes two second side plates 222, and the two second side plates 222 are respectively connected to two opposite side edges of the frame body 221. The two first limiting portions are also installed on the corresponding side edges, so that the first side plate 212, the connecting plate 211 and the second side plate 222 jointly enclose the installation groove 21.

[0080] In some embodiments, both the first side plate 212 and the second side plate 222 are perpendicularly connected to the connecting plate 211 to form a rectangular installation groove structure.

[0081] In some embodiments, the mounting bracket 2 is a sheet metal part, the frame body 221 is a rectangular frame structure, and the first side plate 212, the connecting plate 211 and the second side plate 222 are all strip-shaped plate structures, so that the frame body 221, the first side plate 212, the connecting plate 211 and the second side plate 222 can be processed from a single sheet metal substrate.

[0082] For specific reference, Figure 12 as shown, the cutting part 3 shown by the hatching is the part that needs to be cut off in the sheet metal base material. After cutting, the frame body 221, the first side plate 212, and the connecting plate 211 are further bent, and the second side plate 222 is further connected to the frame body 221 (which can be welding, screw connection, riveting, etc.), and the forming of the mounting bracket 2 can be realized.

[0083] This manufacturing process requires less material, fewer sheet metal parts, and a simple forming process. In the large-scale production and manufacturing process, such a structural design can help improve the overall production and processing efficiency of the filtering device.

[0084] Reference Figure 7 as shown, in some embodiments, a plurality of first mounting holes 223 are arranged along the circumferential direction of the mounting frame 22.

[0085] The plurality of first mounting holes 223 are used to mount the filtering device to the air-conditioning equipment. The number or the interval distance of the distribution of the first mounting holes 223 can be designed according to the specification size of the air outlet of the air-conditioning equipment.

[0086] Next, the structure of a specific embodiment of the filtering device of the present utility model will be described.

[0087] Reference Figures 1 - 8 as shown, the filtering device of the present application includes a filter screen 1 and a mounting bracket 2 for mounting the filter screen 1.

[0088] Among them, the mounting bracket 2 includes a mounting frame 22 and a first limiting part. The mounting frame 22 includes a frame body 221 and a second side plate 222. The first limiting part includes a connecting plate 211 and a first side plate 212. The connecting plate 211 is connected between the first side plate 212 and the frame body 221, and the frame body 221, the connecting plate 211, and the first side plate 212 are integrally connected sheet metal structures, and the second side plate 222 is welded to the frame body 221.

[0089] Specifically, the first side plate 212 and the second side plate 222 are arranged oppositely, and both the first side plate 212 and the second side plate 222 are perpendicular to the connecting plate 211, so as to jointly form a mounting groove 21 for mounting the filter screen by the first side plate 212, the second side plate 222, and the connecting plate 211. The filter screen 1 is inserted into the inner space of the mounting groove 21, and the filter screen 1 can slide relative to the mounting groove 21.

[0090] In this embodiment, the filtering device includes two filter screens 1; the filter screen 1 is a filter screen made of PET material or PP material.

[0091] In this embodiment, the filtering device includes two mounting grooves 21, which are respectively located on two opposite side edges of the frame body 221.

[0092] Both the connecting plate 211 and the first side plate 212 are located on one side of the frame body 221. A notch 213 is provided in the middle of the first side plate 212, so that the filter screen 1 can be inserted into or pulled out relative to the mounting groove 21 through the space between the notches 213 of the two mounting grooves 21.

[0093] Next, the material and processing method of the mounting bracket 2 in this embodiment will be introduced.

[0094] The mounting bracket 2 is made of a hot-dip galvanized steel plate with a thickness of 1.15 mm of Q235A material, and its surface has been oiled to improve its corrosion resistance and processing performance.

[0095] Reference Figure 1 As shown in the lower part of the figure, the mounting bracket 2 of the present application is an overall sheet metal structure.

[0096] Specifically referring to Figure 7 As shown, six first mounting holes 223 are provided on the frame body 221 along its circumferential direction, so that the frame body 221 can be connected to the air-conditioning equipment through the first mounting holes 223 and screws; and four first welding points 224 are arranged on the frame body 221 along its circumferential direction, so that the frame body 221 can be connected to the second side plate 222 by spot welding. Correspondingly, referring to Figure 8 As shown, six second mounting holes 222a corresponding to the first mounting holes 223 are provided on the second side plate 222 to be used as through holes to avoid the screws; and four second welding points 222b corresponding to the first welding points 224 are also provided on the second side plate 222.

[0097] Taking six mounting holes as an example in this embodiment, in actual applications, the number of mounting holes can be flexibly set according to production requirements, such as four, eight, ten, etc. Similarly, the number of welding points can also be set according to requirements. For example, if the overall size of the mounting bracket 2 is relatively large, the number of welding points can be appropriately increased.

[0098] Reference Figure 12 As shown, a processing drawing of blanking the mounting bracket 2 by a sheet metal die in this embodiment is shown, that is, the unfolded structure of each component forming the mounting bracket 2 is shown. Among them, the two second side plates 222 have exactly the same structure and are arranged symmetrically up and down in Figure 12 . When performing sheet metal blanking processing, the cutting part 3 is the tool setting position during processing. After the blanking process, the two second side plates 222 are formed on the inner side of the frame body 221.

[0099] Furthermore, the first limiting part is bent and formed by the lower die of the numerical control bending machine, and the second side plate 222 and the frame body 221 are welded to realize the formation of the mounting groove 21.

[0100] During the above processing, very little waste material is generated, which can achieve the maximum utilization efficiency of sheet metal materials, with low cost. And only simple flanging operations are required during the processing, resulting in high efficiency. Also, due to the small amount of materials, complex connections are not needed, and a simple and beautiful visual effect can be obtained, greatly improving the appearance of the mounting bracket 2.

[0101] Based on the above filtering device, the present application also provides an air conditioning device. The filtering device of the present application can be applied to air conditioning devices such as duct machines to achieve the air purification effect. However, the filtering device of the present application is not limited to being applied to duct machines, and can also be other structures, such as being used in combination with wall-mounted units or floor-standing units.

[0102] In this embodiment, the mounting bracket 2 is basically in a rectangular structure. Taking the air conditioning device to which it is applied as a duct machine as an example, the filtering device is applied to the purification module of the duct machine.

[0103] Since the usage environments of air conditioning devices are diverse, especially duct machines are usually embedded in the ceilings of buildings, and there are various types of buildings, there are various implementation methods for the filtering device and air conditioning device of the present application.

[0104] The following introduces a specific embodiment of applying the filtering device of this embodiment to an air conditioning device (duct machine).

[0105] Installing the filtering device of the present application at the return air inlet of the duct machine can effectively filter toxic and harmful substances such as formaldehyde, PM2.5, and bacteria in the air conditioning circulation air system. In this embodiment, the filter screen 1 is taken as an example of the return air filter screen, but it is not limited to the filter screen at the return air, and can also be the filter screen at the air outlet.

[0106] Refer to Figure 2 As shown, the arrow direction in the figure is the flow direction of the air flow, and the downward arrow direction is the return air direction of the duct machine. The return air blows from above the filter screen 1 to below it.

[0107] Since the purification module is a non-long-lasting material and needs to be replaced regularly, the convenience of disassembling the purification module is particularly important. In this embodiment, there are mainly two disassembly methods for the filtering device.

[0108] The process of the first disassembly scheme in this embodiment is as shown in Figure 9 、 Figure 10 and Figure 11 As shown, slide the two filter screens 1 away from the middle of the mounting bracket 2 to both sides, that is, slide them to the left and right along the mounting groove 21 respectively. The disassembly process is successively Figure 9 → Figure 10 → Figure 11, until both filter meshes 1 are completely detached from the installation groove 21. This disassembly solution is mainly applicable to the situation where there are no walls on both sides of the air duct machine. Users can remove the filter mesh 1 from both sides. If a new filter mesh 1 needs to be replaced, the installation process is exactly the opposite of the above disassembly process.

[0109] The second disassembly solution of this embodiment is as Figure 4 , Figure 3 and Figure 1 and as shown. Figure 4 is the state where the filter mesh 4 is flatly installed on the mounting bracket 2. First, as Figure 3 shown, pull out one end of the right filter mesh 1, lift the pulled-out end by the height of the thickness of a filter mesh, and then pull it out along the position of the notch 213. Similarly, as Figure 1 shown, pull out one end of the left filter mesh 1, lift the pulled-out end by the height of the thickness of a filter mesh, and then pull it out along the position of the notch 213. If a new filter mesh 1 needs to be replaced, the installation process is exactly the opposite of the above disassembly process.

[0110] In the actual application process, the disassembly process of the filter mesh 1 is not limited to the above single method or sequence, and the methods of disassembling from both ends and from the middle notch 213 can be comprehensively used.
