[0058] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0059] In the related art, in order to make the shell assembly applicable to filter parts of various sizes, a space large enough is usually provided inside the frame, so that even a large-size filter part can be installed therein. However, this can cause the small-size filter part to shake or even be tilted in the frame under the impact of the airflow when the filter module is working, so that a gap exists between the small-size filter part and the frame, that is, an airflow channel exists between the filter part and the frame, resulting in leakage of untreated air and affecting the filtering effect. In view of this, the applicant considers that two guide rails capable of fixing the small-size filter part and capable of being extracted relative to the frame are arranged in the frame, so that the two opposite sides of the filter part can be supported by the two guide rails respectively, avoiding the problem of air leakage caused by tilting and shaking of the filter part under the impact of the airflow, and facilitating replacement of the filter part. However, the applicant finds that due to differences in size of filter parts of different functions and different manufacturers, for example, for a filter part of one inch in thickness, filter parts provided by different manufacturers can differ in thickness by several millimeters to tens of millimeters. This leads to the fact that even if the guide rails are installed, the fixing effect can still be poor in actual application. Moreover, a gap still exists between the filter part and the wall surface of the frame without the guide rails, and the problem of air leakage cannot be completely eliminated. Furthermore, the arrangement of the guide rails also causes the frame to be unable to effectively apply to large-size filter parts.

[0060] In view of this, please refer to Figures 1 to 11 In some embodiments of the utility model, a shell assembly 100 is provided, which is used for a filter module 10. The filter module 10 comprises the shell assembly 100 and further comprises a filter part 200, the filter part 200 is used for filtering air, and the filtering treatment can be at least one of dust removal, dehumidification or purification (such as formaldehyde removal) and the like. The filter module 10 is used for obtaining external air, and the external air is discharged from the filter module 10 after passing through the filter part 200 in the shell assembly 100, so as to realize filtering treatment of air. The filter module 10 can be used in any device that needs to filter air, for example, the filter module 10 can be used in an air conditioning system, a fresh air system or an air purifier. In order to facilitate description, in the following embodiments, the filter module 10 is used in an air conditioning system, and an air handling unit 1 for heat exchange and filtering treatment of air is exemplarily illustrated.

[0061] Please refer to Figures 1 to 9, the housing assembly 100 comprises a frame 110 and a holding frame 120, the frame 110 is internally provided with a cavity 111, and the frame 110 is provided with an air inlet 112 and an air outlet 113 respectively communicating with the cavity 111. For the sake of description, the direction from the air inlet 112 to the air outlet 113 is defined as the first direction X, and the axis of the frame 110 is parallel to the first direction X. The first direction X can also be the air flow direction in the frame 110. After the filter part 200 is arranged in the cavity 111, the first direction X can be parallel to the thickness direction of the filter part 200 to ensure the smoothness of the air flow. The holding frame 120 is detachably connected to the frame 110 and accommodated in the cavity 111, and the holding frame 120 can be used to position and support the filter part 200. The holding frame 120 surrounds the axis and extends in a direction perpendicular to the first direction X, that is, the holding frame 120 is arranged in the form of a ring around the axis parallel to the first direction X.

[0062] When the holding frame 120 is installed in the frame 110, a first space 130 is formed between the holding frame 120 and the air outlet 113. Please refer to Figure 2 , the first space 130 can be used to accommodate the filter part 200 of the first size. In addition, please refer to Figure 6 , a second space 140 is formed between the holding frame 120 and the air inlet 112, and the second space 140 is suitable for accommodating the filter part 200 of the second size. The sizes of the filter parts 200 accommodated by the first space 130 and the second space 140 are different, which ensures the adaptability of the filter parts 200 of different sizes. In addition, since the side of the holding frame 120 located in the first space 130 and facing the air outlet 113 can abut against the edge of the side wall of the filter part 200 away from the air outlet 113, and the side of the holding frame 120 located in the second space 140 and facing the air inlet 112 can abut against the edge of the side wall of the filter part 200 away from the air inlet 112, the filter part 200 can be effectively fixed while realizing self-sealing and reducing air leakage. In this way, the problems of unstable fixation and air leakage caused by the size difference of the filter part 200 can be effectively solved, and the versatility and use efficiency of the filter module 10 are improved.

[0063] Please refer to Figure 7When the abutting frame 120 is detached from the frame 110, a third space 150 is formed between the air inlet 112 and the air outlet 113, which can accommodate a larger size filter part 200 to achieve higher air filtration efficiency. In this embodiment, the frame 110 can be provided with a stop bar at the air outlet 113, so that the filter part 200 is tightly attached to the edge of the side wall of the air outlet 113, further reducing air leakage and improving filtration efficiency. The detachable design of the abutting frame 120 enables the filter module 10 to maintain excellent performance in different application scenarios, further enhancing its adaptability and reliability. In other words, the first space 130, the second space 140 and the third space 150 can all accommodate filter parts 200 of different sizes, ensuring the flexibility and efficiency of the filter module 10 under different size requirements, and significantly improving the overall effect of air treatment.

[0064] Compared with the traditional fixed filter module 10, in this application, the abutting frame 120 is detachably connected to the frame 110, so that the cavity 111 is divided into multiple spaces of different sizes, thereby improving the compatibility of the housing assembly 100 for filter parts 200 of different sizes, avoiding the tediousness of frequent replacement of the housing assembly 100, and reducing maintenance costs. Moreover, the abutting frame 120 is arranged around the outer periphery of the axis of the frame 110, so that it can provide uniform support force to the filter part 200 while effectively abutting the side of the filter part 200 away from the air outlet 113 and the air inlet 112, thereby sealing the air flow path between the filter part 200 and the frame 110, reducing air leakage due to mismatched size of the filter part 200, and further improving the filtration efficiency and stability of the overall system.

[0065] In some embodiments, the first space 130, the second space 140 and the third space 150 can accommodate the filter part 200 alternatively. In order to be able to adapt to filter parts 200 of different thickness ranges, in this embodiment, the width dimension of the first space 130, the width dimension of the second space 140 and the width dimension of the third space 150 are all different along the first direction X, so that the housing assembly 100 can at least adapt to filter parts 200 of three thickness dimensions. When it is necessary to switch filter parts 200 of different thicknesses, the new filter part 200 can be arranged in the space corresponding to the width. In other embodiments, the first space 130, the second space 140 and the third space 150 can simultaneously accommodate filter parts 200 in multiple spaces. Specifically, when the filter module 10 is working, the first space 130 and the second space 140 can simultaneously be provided with filter parts 200. When the first space 130 and the second space 140 can simultaneously be provided with filter parts 200, the width dimension of the first space 130 along the first direction X and the width dimension of the second space 140 along the first direction X can be the same or different, and when the width dimension of the first space 130 along the first direction X and the width dimension of the second space 140 along the first direction X are the same, the same thickness filter parts 200 can be simultaneously arranged in the first space 130 and the second space 140, so as to realize the effect of improving the thickness of the filter part 200 (compared with the scheme of alternatively arranging filter parts 200 in the first space 130 and the second space 140).

[0066] When the width dimension of the first space 130, the width dimension of the second space 140, and the width dimension of the third space 150 are all different along the first direction X, in some embodiments, the width dimension of the first space 130 is less than the width dimension of the second space 140, and the width dimension of the second space 140 is less than the width dimension of the third space 150 along the first direction X. In this way, the first space 130 can be adapted to fit the filter portion 200 having a smaller thickness, the second space 140 can be adapted to fit the filter portion 200 having a relatively larger thickness than the first space 130, and the third space 150 can be adapted to fit the filter portion 200 having the largest thickness. For example, in some embodiments, the width dimension of the first space 130 can be slightly greater than one inch along the first direction X, such that the first space 130 is adapted to accommodate the filter portion 200 having a thickness of substantially one inch; the width dimension of the second space 140 can be slightly greater than two inches, such that the second space 140 is adapted to accommodate the filter portion 200 having a thickness of substantially two inches; and the width dimension of the third space 150 can be slightly greater than four inches, such that the third space 150 is adapted to accommodate the filter portion 200 having a thickness of substantially four inches. In other embodiments, the width dimension of the first space 130 can also be greater than the width dimension of the second space 140, and the width dimension of the first space 130 is less than the width dimension of the third space 150 along the first direction X. In this way, the filter portion 200 adapted by the first space 130 can have a thickness dimension greater than the filter portion 200 adapted by the second space 140. It is noted that in the present application, "substantially", "slightly greater than" are defined as within a range of plus or minus ten percent. For example, "substantially one inch" means a dimension within a range of 0.9 inches to 1.1 inches; "substantially two inches" means a dimension within a range of 1.8 inches to 2.2 inches; and "substantially four inches" means a dimension within a range of 3.6 inches to 4.4 inches.

[0067] For ease of understanding, define the plane perpendicular to the first direction X as the projection plane, and the abutting frame 120 forms a first projection on the projection plane. The outer contour and the inner contour of the first projection are both rectangular. In this way, not only can the filter part 200 be provided with stable physical support, but also the pressure can be effectively distributed, reducing the displacement or deformation problem that the filter part 200 may encounter during use. Moreover, the rectangular outer contour of the abutting frame 120 enables the circumferential wall along the second direction Y to effectively fit the frame 110, thereby avoiding air leakage through the gap between the abutting frame 120 and the frame 110, further ensuring the filtering effect. The inner contour of the first projection formed by the abutting frame 120 on the projection plane is rectangular, which can effectively improve the compatibility of the abutting frame 120 to the filter part 200 on the market, ensuring effective support and sealing of the filter part 200 while reducing the effective working area of the abutting frame 120 to the filter part 200, improving the filtering efficiency. In addition, the rectangular design facilitates manufacturing and installation, reducing production costs and improving assembly efficiency. In some embodiments, the inner contour of the abutting frame 120 can also be other geometric shapes, including but not limited to circular, elliptical, and polygonal, to meet the needs of different shapes of filter parts 200, ensuring the maximization of the filtering effect.

[0068] For ease of expression, define the direction perpendicular to the first direction X as the second direction Y, and define the direction perpendicular to the first direction X and the second direction Y as the third direction Z. In some embodiments, the abutting frame 120 includes two positioning parts arranged opposite along the second direction Y and two blocking conditions 122 arranged opposite along the third direction Z. One of the blocking conditions 122 connects one end of the two positioning parts along the third direction Z at both ends along the second direction Y, and the other blocking condition 122 connects the other end of the two positioning parts along the third direction Z at both ends along the second direction Y. The blocking condition 122 and the positioning part form a stable frame structure, ensuring the rigidity and stability of the abutting frame 120 in all directions, effectively preventing displacement of the filter part 200 under high-speed airflow impact. It should be noted that the connection mode of the blocking condition 122 and the positioning part includes but is not limited to welding, riveting, threaded connection, etc. The blocking condition 122 and the positioning part can also be manufactured as one whole by using an integrated molding process including but not limited to injection molding, stamping molding, sheet metal molding, etc. to enhance the overall structural strength of the abutting frame 120, further improving its durability and reliability under complex working conditions, ensuring long-term stable operation of the filtering system.

[0069] The blocking condition 122 and the positioning part on one side of the first space 130 are adapted to contact the edge of the side wall of the filter part 200 away from the air outlet 113, and the blocking condition 122 and the positioning part on one side of the second space 140 are adapted to contact the edge of the side wall of the filter part 200 away from the air inlet 112. In other words, the blocking condition 122 and the positioning part can seal the circumferential edge of the filter part 200 in all directions, effectively preventing air leakage from the edge to affect the filtering effect. It should be noted that the blocking condition 122 and the positioning part approach the side wall of the frame 110 in the direction perpendicular to the first direction X and abut the inner wall of the frame 110, forming a close fit, further enhancing the sealing performance. Alternatively, the blocking condition 122 and the positioning part approach the side wall of the frame 110 in the direction perpendicular to the first direction X and are provided with a sealing pad, ensuring the seamless docking of the abutting frame 120 and the inner wall of the frame 110, eliminating small gaps and improving the overall sealing effect, thereby ensuring the filtering effect of the filter part 200.

[0070] Please refer to Figure 2 and Figure 3 , and Figures 9 to 11 In order to realize the stable connection of the abutting frame 120 and the frame 110, the frame 110 is provided with a first positioning part 114, and the first positioning part 114 is located in the cavity 111. The side wall of the abutting frame 120 facing the frame 110 is provided with a second positioning part 121, which is detachably connected to the first positioning part 114, so as to facilitate the installation or disassembly of the abutting frame 120 on the frame 110, and also facilitate the replacement of the filter part 200. In some embodiments, the first positioning part 114 can be a buckle structure or a slot structure, and the corresponding second positioning part 121 can be a hook structure or a latch structure, etc. In this way, the abutting frame 120 can be installed through the insertion or locking action. Similarly, by reversing the extraction or unlocking action, the abutting frame 120 can be disassembled, thereby improving the convenience of using the equipment.

[0071] In order to improve the positioning accuracy and stability, a magnetic element can be introduced between the first positioning part 114 and the second positioning part 121. For example, the first positioning part 114 can be designed as a groove 1141 with a built-in magnet, and the second positioning part 121 is provided with a protrusion made of metal sheet or other magnetic material. When the abutting frame 120 approaches the frame 110, the magnetic force will automatically guide the two to align and closely fit, ensuring high positioning accuracy. At the same time, this method can also prevent loosening or misalignment caused by vibration to a certain extent. In addition, a sealing ring can be added around the positioning part to enhance the overall sealing effect and avoid air leakage affecting the filtering effect.

[0072] For the convenience of description, a direction perpendicular to the first direction X is defined as the second direction Y. In a specific implementation, the first positioning portions 114 are arranged on opposite sides of the cavity 111 along the second direction Y, and the first positioning portions 114 extend along the first direction X. Correspondingly, the second positioning portions 121 are arranged on opposite sides of the holding frame 120 along the second direction Y, and extend along the first direction X. The second positioning portions 121 are detachably connected to the first positioning portions 114, so that the holding frame 120 can be removed from or installed in the cavity 111 through the air inlet 112 or the air outlet 113. During installation, only need to align the second positioning portion 121 at one end of the holding frame 120 along the second direction Y with the first positioning portion 114 at one end of the frame 110 along the second direction Y, and then push the holding frame 120 along the first direction X until the second positioning portion 121 at the other end of the holding frame 120 is completely connected to the first positioning portion 114 corresponding to the holding frame 120 on the frame 110. During removal, the reverse operation can be performed. This not only improves the assembly efficiency, but also ensures the stability and reliability of the holding frame 120 during use.

[0073] In some embodiments, the holding frame 120 can also be installed or removed from the frame 110 along the third direction Z. Specifically, please refer to Figures 1 to 10 The frame 110 includes a frame body 115 and a cover plate 116. The frame body 115 has an outlet 117 on one side along the third direction Z, which can be used for the holding frame 120 or the filter part 200 to enter or exit, and can also be used for the installation or removal of the holding frame 120. The cover plate 116 is detachably connected to the frame body 115 and is configured to be able to close or open the outlet 117. When it is necessary to install or replace the filter part 200, only need to open the cover plate 116, insert the holding frame 120 or the filter part 200 into the frame body 115 along the third direction Z through the outlet 117, and ensure that the second positioning portion 121 is accurately connected to the first positioning portion 114 on the frame body 115, the edge of the filter part 200 is held by the holding frame 120, and then the cover plate 116 is closed. During removal, the reverse operation is performed, the cover plate 116 is opened, and the holding frame 120 or the filter part 200 is extracted. It should be noted that in other embodiments, the cover plate 116 can also be rotatably connected to the frame body 115, and the opening and closing of the outlet 117 can be realized by rotating the cover plate 116.

[0074] wherein, for the purpose of understanding, a direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z, the first positioning part 114 is arranged on both sides of the cavity 111 along the second direction Y and extends along the third direction Z, and the second positioning part 121 is arranged on both sides of the holding frame 120 along the second direction Y, and the second positioning part 121 is detachably connected to the first positioning part 114, so that the holding frame 120 can be installed or removed through the outlet 117. When it is necessary to replace the filter part 200, only the cover plate 116 needs to be opened, the holding frame 120 or the filter part 200 is pulled out along the third direction Z, and then a new filter part 200 is inserted, ensuring that the edge of the filter part 200 abuts against the holding frame 120, and finally the cover plate 116 is closed, so that the replacement is completed. Similarly, when it is necessary to remove the holding frame 120, the cover plate 116 is opened and the holding frame 120 is pulled out along the third direction Z.

[0075] Referring to Figure 2 and Figure 3 In some embodiments, the first positioning part 114 can be a groove 1141 recessed in the frame 115 along the second direction Y, and the second positioning part 121 is a protrusion protruding from the holding frame 120 along the second direction Y, which is configured to be slidably connected to the groove 1141, so that the holding frame 120 can be easily installed or removed along a predetermined direction. For example, during installation, the protrusion on the holding frame 120 is aligned with the groove 1141 on the frame 110, and is slid along the groove 1141 until it reaches the correct position. This not only simplifies the assembly process, but also ensures the stability of the connection between the frame 110 and the holding frame 120. In addition, the first positioning part 114 and the second positioning part 121 are connected by sliding, which can effectively reduce the displacement of components such as the holding frame 120 and the filter part 200 caused by vibration or other external forces during installation or removal, thereby ensuring the stability and reliability of the filtering effect.

[0076] In order to further improve the flexibility and adaptability of the system, a spring device or a resilient material can be provided inside the groove 1141, which can provide a certain buffering effect when the protrusion is inserted, and at the same time increase the friction to prevent accidental sliding. In addition, limiting devices such as buckles or locking mechanisms can be designed at both ends of the groove 1141 to ensure that the holding frame 120 will not loosen after being installed in place due to vibration or other reasons.

[0077] Referring to Figure 3In some embodiments, the first positioning portion 114 includes a first plate and a second plate, wherein the groove 1141 has opposite first and second ends in the first direction X. The first plate is located at the first end of the groove 1141, and is connected to the frame 115 at one end in the first direction X away from the second end, and extends towards the second end at the other end, covering part of the opening of the groove 1141. The second plate is located at the second end of the groove 1141, and is fixedly connected to the frame 115 at one end in the first direction X away from the first end, and extends towards the first end at the other end, covering part of the opening of the groove 1141. The second positioning portion 121 includes a first protrusion 1211 and a second protrusion 1212 arranged opposite in the first direction X. The first protrusion 1211 is configured to be clamped between the side wall of the groove 1141 facing the filter portion 200 and the side wall of the first plate away from the filter portion 200, and the second protrusion 1212 is configured to be clamped between the side wall of the groove 1141 facing the filter portion 200 and the side wall of the second plate away from the filter portion 200. Thus, the abutting frame 120 can be accurately inserted into the groove 1141 by the first protrusion 1211 and the second protrusion 1212 when installed, and the position is kept unchanged by the limitation provided by the first plate and the second plate. In this way, not only the installation efficiency can be improved, but also the close fit between the abutting frame 120 and the frame 115 is ensured, effectively preventing displacement caused by external force, further enhancing the stability and service life of the overall structure.

[0078] It can be understood that the first plate body 1142 can be integrally connected with the frame 115, that is, the first plate body 1142 can be connected with the frame 115 by welding or the like, or can be formed as a whole structure by stamping, sheet metal forming, injection molding or the like. Thus, the sealing and strength between the first plate body 1142 and the frame 115 are ensured. Similarly, the second plate body 1143 can also be integrally formed with the frame 115 by similar processes, to ensure the close combination of the second plate body 1143 and the frame 115.

[0079] In order to improve the sealing performance and stability, a sealing strip or rubber gasket can be added to the part of the first plate and the second plate in contact with the groove 1141. This not only prevents air leakage, but also absorbs vibration, further enhancing the stability of the system.

[0080] In some embodiments, to further ensure the sealing between the first positioning part 114 and the second positioning part 121. In some embodiments, the first plate body 1142 is located on one side of the groove 1141 close to the air inlet 112 and is arranged in an inclined manner towards the filter part 200 along the second direction Y, so as to facilitate the smooth insertion of the first protrusion 1211 into the groove 1141 and reduce the installation difficulty. Moreover, the first plate body 1142 arranged in an inclined manner can also play a sealing role. Specifically, when the filter part 200 is pushed into the second space 140 with the frame 120, the first protrusion 1211 will slide along the first plate body 1142 until it reaches the predetermined position, at which time the end of the first plate body 1142 close to the second plate body 1143 will abut against the side wall of the filter part 200 along the second direction Y, thereby ensuring the close fit between the filter part 200 and the frame 115 and effectively preventing the air flow from leaking through the gap between the second positioning part 121 and the first positioning part 114. At the same time, the first plate body 1142 arranged in an inclined manner can also provide additional support force to prevent the filter part 200 from shifting or loosening during use. This not only enhances the stability and reliability of the system, but also ensures the persistence of the filtering effect.

[0081] The second plate body 1143 can also be designed in a similar inclined manner to the first plate body 1142 to ensure the smooth insertion of the second protrusion 1212 into the groove 1141. In some embodiments, the second plate body 1143 is located on the side close to the first space 130, and the side wall of the second plate body 1143 close to the filter part 200 is perpendicular to the second direction Y, i.e. the second plate body 1143 is not arranged in an inclined state. Since the air flow flows from the air inlet 112 to the air outlet 113, it will flow from the second space 140 to the first space 130, and the vertical design of the second plate body 1143 helps to guide the air flow to flow smoothly, avoiding air flow turbulence caused by inclination, thereby improving the filtering effect. Since the inclination direction of the first plate body 1142 is consistent with the direction of the air flow, it will not interfere with the air flow path, but can better utilize the principle of air flow dynamics to reduce the leakage of untreated air and ensure the optimization of the filtering effect.

[0082] To further improve the sealing performance and stability of the system, in some embodiments, the housing assembly 100 further comprises a seal disposed between the frame 110 and the abutting frame 120 and extending around the axis and in a direction perpendicular to the first direction X. The arrangement of the seal can prevent untreated air from directly bypassing the filter part 200 and entering the air outlet 113 between the abutting frame 120 and the frame 110, ensuring the filtering effect of the filter module 10. Specifically, the seal can be made of materials including but not limited to rubber with high elasticity, foam and other materials with sealing performance. During installation, when the abutting frame 120 is inserted into the frame 110, the seal will be compressed, thereby filling the gap between the frame 110 and the abutting frame 120 and forming a tight sealing connection. This not only prevents air leakage, but also effectively reduces noise levels and improves user experience.

[0083] It should be noted that the side wall of the cover plate 116 facing the cavity 111 has a sealing structure at the installation position of the abutting frame 120 along the first direction X. The sealing structure can be part of the seal or a separate sealing strip. In some embodiments, the sealing structure can be a sealing lip facing the side close to the cavity 111. When the cover plate 116 is closed, the sealing lip tightly abuts the abutting frame 120, further enhancing the sealing effect. The presence of the sealing structure further enhances the sealing performance between the cover plate 116 and the abutting frame 120, ensuring that no leakage occurs when the air flows through.

[0084] Please refer to Figure 4 , Figure 5 and Figure 7 When the filter part 200 is disposed in the first space 130 or the third space 150, in order to further ensure the filtering effect, in some embodiments, the frame 110 further comprises an annular baffle 118 disposed around the axis and extending in a direction perpendicular to the direction, the outer periphery of which is connected to the end of the frame body 115 close to the air outlet 113, and the side wall of the annular baffle 118 away from the air outlet 113 is adapted to abut the edge of the side wall of the filter part 200 facing the air outlet 113. Thus, displacement of the filter part 200 under the impact of the air flow is avoided, ensuring its stable fixation, while preventing untreated air from directly entering the air outlet 113 through the gap between the frame 110 and the filter part 200, ensuring the stability and reliability of the filtering effect.

[0085] The annular baffle 118 can be an annular structure composed of four baffles connected end to end to form an integral structure. Each baffle can be formed by welding end to end to form an integral structure, and the annular baffle 118 can be manufactured by integral molding, including but not limited to die molding, stamping molding, etc. In some embodiments, the frame 115 includes four side plates connected end to end, each side plate corresponding to each baffle. Each side plate and each baffle can be connected by welding to ensure sealing and stability, and easy maintenance. The connection between adjacent side plates includes but is not limited to welding, screwing, splicing, etc. In addition, the side plates and baffles connected to each other can also be manufactured by molding, stamping, sheet metal forming, etc.
