[0060] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to 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.

[0061] Therefore, please refer to Figures 1 to 10The utility model provides a shell assembly 100, this shell assembly 100 can be used to include but not limited to air conditioner, dehumidifier etc. air handling unit 1's filter module 10, wherein, filter module 10 includes the filter part 200 for carrying out filter processing to air. Shell assembly 100 includes frame 110 and tray 120. Frame 110 inside is equipped with the cavity 111, and is provided with the air inlet 112 and the air outlet 113 of the intercommunication cavity 111. Air current passes through air inlet 112 and enters frame 110, after being handled after filter part 200, clean air current is discharged from air outlet 113. Frame 110 can support and fix filter part 200 and tray 120 set in it, ensure filter effect.

[0062] For convenience of expression, define parallel to the direction by air inlet 112 points to air outlet 113 as first direction X, and the axis of frame 110 is parallel to this first direction X. Tray 120 detachably connects to frame 110 and is contained in cavity 111. Please refer to Figure 1 And Figure 4 Tray 120 includes annular frame 121 and annular baffle 122, wherein annular frame 121 extends along first direction X and is arranged around the circumferential side of the axis of frame 110, and annular baffle 122 extends along the direction perpendicular to first direction X and is arranged around the circumferential side of the axis of frame 110. Annular frame 121 is connected to the outer periphery of annular baffle 122 at one end close to air outlet 113, so that the side wall of annular baffle 122 away from air outlet 113 can be in close contact with the edge of the side of filter part 200 facing air outlet 113, so as to effectively fix filter part 200, while avoiding the air current entering cavity 111 from air inlet 112 flowing out through the gap between filter part 200 and tray 120, ensuring the sealing property in the filter process, thereby improving the filter efficiency, avoiding the unfiltered air directly entering the system, and ensuring the stability and reliability of the filter effect.

[0063] It should be noted that, since annular baffle 122 is arranged at the side of annular frame 121 close to air outlet 113, when the air current flows in the direction of air outlet 113 after entering cavity 111 from air inlet 112, the air current can exert pressure on filter part 200, so that filter part 200 is more closely attached to annular baffle 122, further reducing the leakage of air current, and enhancing the filter effect.

[0064] For ease of understanding, define the plane perpendicular to the first direction X as the projection plane, the first projection of the annular frame 121 formed on the projection plane can have a rectangular outer contour, which helps to simplify the manufacturing process while ensuring the stability of the structure. The inner contour of the second projection of the annular barrier 122 formed on the projection plane can also be rectangular, which is beneficial to enhance the support of the annular barrier 122 to the filter part 200, ensure that the filter part 200 is stably placed on the tray 120, and thus improve the stability and reliability of the overall system.

[0065] In other words, the annular frame 121 and the annular barrier 122 can both be designed in a rectangular shape for standardized production. The annular frame 121 and the annular barrier 122 can also be designed in other shapes, including but not limited to oval, trapezoidal, etc., to adapt to different sizes and shapes of the filter part 200, thereby achieving wider applicability and better market adaptability.

[0066] In order to adapt to different application scenarios, the first projection outer contour of the annular frame 121 can be circular, elliptical, or other shapes in addition to rectangular. Therefore, the outer contour of the second projection of the annular barrier 122 adapts to the shape of the first projection outer contour. The inner contour of the second projection can also be circular, elliptical, or other shapes in addition to rectangular. For example, in the case of higher space utilization, a circular or elliptical design can be chosen to optimize space layout while providing good sealing effect. The change in the shape of the inner contour of the second projection can also be customized according to different types of filter parts 200 to ensure that the filter part 200 has sufficient contact area with air to achieve optimal filtering performance. In addition, the size of the annular barrier 122 in the direction perpendicular to the first direction X can be designed according to the edge size of the filter part 200. Specifically, the space defined by the inner contour of the second projection formed by the annular barrier 122 in the projection plane is slightly smaller than the edge size of the filter part 200, ensuring that the filter part 200 can tightly fit the annular barrier 122 when installed, preventing air leakage. This design not only ensures the sealing of the filter unit, but also facilitates the user to quickly replace the filter part 200, improving maintenance efficiency.

[0067] It should be noted that the shape of the frame body 110 can not be strictly a cuboid or a square, it can be designed as a cylindrical or other shape according to actual application requirements to adapt to specific installation environment and space limitations. In addition, the materials of the annular frame 121 and the annular barrier 122 can be selected to have high strength and corrosion resistance, to increase the durability and corrosion resistance of the entire shell assembly 100.

[0068] In some embodiments, the annular baffle 122 comprises four baffle conditions, each of which is connected to each other in a body to form an integrated annular baffle 122. Each baffle condition can be formed by welding to each other in a body, i.e., to form the annular baffle 122. The annular baffle 122 can also be manufactured by one-piece forming, including but not limited to die forming, stamping, etc.

[0069] In other embodiments, the annular baffle 122 comprises four baffle conditions, and the annular frame 121 comprises four side plates connected to each other in a body, each baffle condition being connected to each side plate one by one. Each side plate and each baffle condition 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 baffle conditions connected to each other can also be manufactured by one-piece forming, including but not limited to die forming, stamping, sheet metal forming, etc.

[0070] Please refer to Figure 6 In order to improve the stability of the filter part 200 during operation, the tray 120 further comprises a first abutting piece 123. For ease of description, define the direction perpendicular to the first direction X as the second direction Y, and the annular baffle 122 has a first baffle condition 1221 and a second baffle condition 1222 arranged opposite to each other along the second direction Y. The two ends of the first abutting piece 123 along the second direction Y are connected to the first baffle condition 1221 and the second baffle condition 1222, respectively, so that the first abutting piece 123 can effectively support the filter part 200 when it is impacted by the airflow, avoiding deformation of the filter part 200. Specifically, during the process of the airflow flowing from the air inlet 112 to the air outlet 113, the filter part 200 is easily deformed by the impact of the airflow, causing the edge to be warped relative to the annular baffle 122, affecting the sealing of the annular baffle 122 and the filter part 200. The arrangement of the first abutting piece 123 provides stable support for the filter part 200 and disperses the airflow pressure, ensuring that the filter part 200 remains flat under the impact of the airflow and maintains stable filtering effect.

[0071] In some embodiments, the number of first abutting pieces 123 can be multiple, and each first abutting piece 123 can be arranged at intervals along the third direction Z to ensure uniform dispersion of pressure, the third direction Z being perpendicular to the first direction X and the second direction Y. The material of the first abutting piece 123 can be made of materials including but not limited to high-strength plastic, metal, etc., so as to balance lightness and strength.

[0072] In addition, in other embodiments, please refer to Figure 6, the tray 120 includes a first abutting piece 123 and a second abutting piece 124, and the annular blocking strip 122 includes a first blocking condition 1221 and a second blocking condition 1222 arranged oppositely along the second direction Y, and a third blocking condition 1223 and a fourth blocking condition 1224 arranged oppositely along the third direction Z. The first abutting piece 123 is connected to the first blocking condition 1221 and the second blocking condition 1222 at two ends along the second direction Y, respectively, and the second abutting piece 124 is connected to the third blocking condition 1223 and the fourth blocking condition 1224 at two ends along the third direction Z, respectively, further enhancing the support force of the tray 120 on the filter part 200, ensuring that the filter part 200 can still maintain a stable form under multi-directional airflow impact, effectively prolonging the service life.

[0073] Specifically, the first abutting piece 123 can be connected to the middle part of the first blocking condition 1221 and the second blocking condition 1222, and the second abutting piece 124 is connected to the middle part of the third blocking condition 1223 and the fourth blocking condition 1224, forming a cross support structure, effectively dispersing the airflow impact force, ensuring that the filter part 200 still maintains flatness when subjected to multi-angle stress, thereby maintaining high-efficiency filtering performance. In addition, the surface of the first abutting piece 123 and the second abutting piece 124 can be additionally provided with anti-slip texture, further improving the friction force with the filter part 200 and preventing sliding displacement.

[0074] It should be noted that the number of first abutting pieces 123 and second abutting pieces 124 can be multiple, and adjacent first abutting pieces 123 and adjacent second abutting pieces 124 are arranged with intervals to ensure balanced stress of the overall structure.

[0075] Please refer to Figure 6 and Figure 7 , the tray 120 is provided with a rope 125 on the side away from the annular blocking strip 122. The rope 125 is connected to the opposite sides of the annular frame 121, and the rope 125 is designed to be able to contact the side wall of the filter part 200 away from the air outlet 113. Specifically, when the tray 120 carrying the filter part 200 is installed into the frame body 110, the rope 125 ensures that the filter part 200 is tightly attached to the tray 120, thereby ensuring the sealing and stability of the entire filter module 10. This design not only simplifies the installation and disassembly process of the filter part 200, but also improves the filtering efficiency and reduces the risk of leakage of unfiltered air.

[0076] It should be noted that when the filter module 10 is working, the impact force of the airflow passing through the filter part 200 can make the filter part 200 closely adhere to the annular blocking strip 122, and the tension of the rope 125 makes it further closely adhere to the tray 120, forming a double fixing effect, ensuring that the filter part 200 still maintains stability under strong airflow. When the filter module 10 stops working, the pressure of the airflow acting on the filter part 200 disappears, and the design of the rope 125 keeps the filter part 200 in relative contact with the tray 120, preventing displacement caused by gravity or other external forces, ensuring that the filter part 200 can still quickly recover to the high-efficiency filtering state when starting next time.

[0077] In some embodiments, the rope 125 is configured to have elasticity, so that the tension of the rope 125 can be easily adjusted without using additional tools, ensuring the optimal contact pressure between the filter part 200 and the tray 120. The elastic rope 125 can automatically adapt to different thicknesses of the filter part 200 during installation, while providing continuous support force during operation to prevent the filter part 200 from loosening or shifting due to vibration.

[0078] In other embodiments, at least one end of the rope 125 is designed to be movable relative to the annular frame 121, allowing the length of the part of the rope 125 between the opposite sides of the annular frame 121 to be adjusted. In other words, the user can flexibly adjust the length of the rope 125 according to actual conditions to adapt to different sizes of the filter part 200 or specific operation requirements. For example, in the case where the filter part 200 needs to be quickly replaced, such design greatly simplifies the operation process, saving time and labor cost. In addition, in order to facilitate adjustment, a sliding rail or similar guide device can be provided on the annular frame 121, so that the movement of the rope 125 is smoother, and the fixing effect after each adjustment is ensured. The flexibility of the length of the part of the rope 125 between the opposite sides of the annular frame 121 not only improves the user experience, but also enhances the applicability and practicality of the entire filtering system.

[0079] In some embodiments, the annular frame 121 includes a first side plate 1211 and a second side plate 1212 oppositely arranged along the second direction Y, and a third side plate 1213 and a fourth side plate 1214 oppositely arranged along the third direction Z. The third side plate 1213 is provided with a first through hole in the middle part along the second direction Y, and the fourth side plate 1214 is provided with a second through hole in the middle part along the second direction Y, and the two ends of the rope 125 along the third direction Z are connected to the first through hole and the second through hole respectively. Thus, the rope 125 can provide support force to the filter part 200 while ensuring its installation stability in the annular frame 121.

[0080] In some embodiments, the third side plate 1213 is provided with a first through hole near one end of the first side plate 1211, and the fourth side plate 1214 is provided with a second through hole near one end of the second side plate 1212. The two ends of the rope 125 are connected to the first through hole and the second through hole respectively. That is, the rope 125 is arranged at the diagonal position of the annular frame 121, further enhancing the stability of the structure and the supporting effect of the rope 125, and ensuring that the filter part 200 can maintain the best working state under various working conditions.

[0081] It can be understood that, in some embodiments, the third side plate 1213 is provided with a first through hole near one end of the first side plate 1211, and the third side plate 1213 is provided with a second through hole near one end of the second side plate 1212; the fourth side plate 1214 is provided with a third through hole near one end of the first side plate 1211, and the fourth side plate 1214 is provided with a fourth through hole near one end of the second side plate 1212. The rope 125 includes a first rope and a second rope, the two ends of the first rope are connected to the first through hole and the fourth through hole respectively, and the two ends of the second rope are connected to the second through hole and the third through hole respectively, forming a cross support structure, further improving the overall stability, and ensuring that the filter part 200 can operate efficiently under different loads. The cross support structure formed by the first rope and the second rope on the filter part 200 not only disperses the load pressure, but also optimizes the stress distribution of the rope 125, prolonging the service life.

[0082] Please refer to Figure 6 and Figure 7 In some embodiments, one end of the first rope 1251 can be connected to the first through hole 1213a, and the other end can be connected to the third through hole 1214a. One end of the second rope 1252 can be connected to the second through hole 1213b, and the other end can be connected to the fourth through hole 1214b. In this way, the first rope 1251 is located on one side of the annular frame 121 close to the first side plate 1211, and the second rope 1252 is located on one side of the annular frame 121 close to the second side plate 1212. Such configuration not only enhances the overall supporting force of the rope 125, but also facilitates the installation or disassembly of the filter part 200. The first rope 1251 and the second rope 1252 are arranged near the first side plate 1211 and the second side plate 1212 respectively, ensuring that balanced supporting force is formed on both sides of the filter part 200, avoiding deviation or deformation caused by uneven single-sided stress.

[0083] To enhance the flexibility and adaptability of the system, the third side plate 1211 and the fourth side plate 1212 can be provided with multiple through holes to allow users to select the most appropriate threading position to adjust the position and tension of the rope 125 according to actual needs. In addition, adjustable locking devices can also be added at the ends of the rope 125 to enable users to make adjustments conveniently and quickly without the need for additional tools. This makes the shell assembly 100 suitable for situations that require frequent replacement of the filter part 200 or quick adaptation to different sizes of the filter part 200. In this way, not only can the operation efficiency be improved, but also the optimal performance of the filter part 200 after each installation can be ensured.

[0084] To improve the convenience of installing and dismounting the filter part 200, quick buckle devices can be designed at the connection ends of the first rope 1251 and the second rope 1252 to facilitate quick fixing and releasing of the ropes, reduce operation time, and improve work efficiency. In some embodiments, the rope 125 is configured to be elastically deformed from the side of the annular frame 121 facing the air inlet 112 to the side of the annular frame 121 facing the air outlet 113, thereby providing more operating space for the installation and dismounting of the filter part 200 and ensuring that the maintenance task can be easily completed by the operator. For ease of understanding, the following takes the example of the first rope 1251 being connected to the first through hole 1213a and the third through hole 1214a and the second rope 1252 being connected to the second through hole 1213b and the fourth through hole 1214b to explain the operation process in detail. First, the part of the first rope 1251 between the third side plate 1213 and the fourth side plate 1214 is pushed and flipped to the side of the annular frame 121 facing the air outlet 113, and then the second rope 1252 is also operated in the same way. The first rope 1251 and the second rope 1252 are temporarily located on the side of the air outlet 113 under the blockage of the annular frame 121, so that the side of the annular frame 121 facing the air inlet 112 forms an unobstructed space, facilitating the smooth installation or dismounting of the filter part 200. After the operation is completed, the first rope 1251 and the second rope 1252 are reset to ensure stable operation of the filter part 200.

[0085] Please refer to Figures 8 to 10, the tray 120 comprises a first clamping member 126 and a second clamping member 127 movably connected to the annular frame 121, the first clamping member 126 and the second clamping member 127 are oppositely arranged along the second direction Y. The annular frame 121 comprises a first side plate 1211 and a second side plate 1212 oppositely arranged along the second direction Y, the first clamping member 126 is connected to an end of the first side plate 1211 away from the air outlet 113, and the second clamping member 127 is connected to an end of the second side plate 1212 away from the air outlet 113. The first clamping member 126 can be switched from the first state to the second state (or from the second state to the first state). When in the first state, the first clamping member 126 is elastically deformed and moves away from the filter part 200 to facilitate the installation or removal of the filter part 200. When switched to the second state, the first clamping member 126 returns to its original position, and the side of the first clamping member 126 facing the filter part 200 abuts against the filter part 200 or its corresponding first side plate 1211, thereby tightly clamping the filter part 200 and ensuring its stability.

[0086] Specifically, the first clamping member 126 can adopt a spring structure. When it is necessary to install or replace the filter part 200, the user can offset the end of the first clamping member 126 away from the annular baffle 122 in a direction away from the filter part 200 by applying an external force, at this time the first clamping member 126 is elastically deformed and inclined or curved compared to the wall surface of the annular frame 121, the first clamping member 126 enters the first state, thereby providing sufficient space when installing or removing the filter part 200. After the filter part 200 is installed in place, the force applied to the first clamping member 126 is removed so that it automatically returns to the second state, tightly abutting the filter part 200 and providing necessary support and positioning functions. Such a structure not only simplifies the operation process, but also improves the stability and reliability of the system.

[0087] Similarly, the second clamping member 127 can also be configured to be switchable between the first state and the second state, when in the first state, the second clamping member 127 is elastically deformed and moves away from the filter part 200 to facilitate installation or removal. When switched to the second state, the second clamping member 127 returns to its original position, tightly clamping the filter part 200 and ensuring its stability. The second clamping member 127 can also adopt a similar spring structure to achieve the same function. In some embodiments, one of the first clamping member 126 and the second clamping member 127 can be switched between the first state and the second state, and the other remains fixed, to simplify the structure design and simplify the installation or removal operation of the filter part 200.

[0088] Please refer to Figure 8The first anti-disengagement part 1261 is arranged on the side of the first clamping part 126 away from the air outlet 113 and facing the filter part 200, and extends along the second direction Y and protrudes from the first side plate 1211. The second anti-disengagement part 1271 is arranged on the side of the second clamping part 127 away from the air outlet 113 and facing the filter part 200, and extends along the second direction Y and protrudes from the second side plate 1212. The side of the first anti-disengagement part 1261 and the second anti-disengagement part 1271 away from the air inlet 112 can receive the side of the filter part 200 away from the air outlet 113, thereby further supporting the filter part 200 and preventing it from moving or disengaging during use, thereby enhancing the stability of the overall structure. In some embodiments, the first anti-disengagement part 1261 and the second anti-disengagement part 1271 can be serrated or protruding, effectively preventing the filter part 200 from sliding.

[0089] It should be noted that, please refer to Figure 9 For a filter part 200 with a thickness of one inch, the side of the first anti-disengagement part 1261 and the second anti-disengagement part 1271 away from the air inlet 112 can abut the edge of the side of the filter part 200 away from the air outlet 113, ensuring that the filter part 200 is stably positioned in the tray 120. Please refer to Figure 9 For a filter part 200 with a thickness of more than one inch (such as a filter part 200 with a thickness of 2 inches, 4 inches, etc.), the opposite ends of the first anti-disengagement part 1261 and the second anti-disengagement part 1271 along the second direction Y can be clamped to the opposite sides of the filter part 200 along the second direction Y, thereby ensuring the stability of the filter part 200 while achieving compatibility with filter parts 200 of different thicknesses.

[0090] It can be understood that the size of the annular frame 121 along the first direction X can be adapted to a filter part 200 with a thickness of one inch. For the installation of thicker filter parts 200, the design of the first clamping part 126, the second clamping part 127, and even the first anti-disengagement part 1261 and the second anti-disengagement part 1271 abutting the opposite sides of the filter part 200 along the second direction Y allows the annular frame 121 to adapt to filter parts 200 of different thicknesses, ensuring that it can maintain efficient and stable filtering performance in various use scenarios. In some embodiments, the annular frame 121 can also be designed to adjust its size along the first direction X to be suitable for filter parts 200 of different thicknesses.

[0091] To further improve the mounting stability of the tray 120 to the filter part 200, in some embodiments, the annular frame 121 comprises four side plates connected head to tail with each other, and each side plate is arranged to be inclined towards the axis of the tray 120 along the second direction Y, forming an inwardly tapered structure to enhance the gripping force to the filter part 200. Alternatively, at least one pair of oppositely arranged two side plates among the four side plates are arranged to be inclined towards the axis of the tray 120 along the second direction Y. In other embodiments, the surface of each side plate facing the side of the filter part 200 is provided with anti-skid protrusions which can effectively increase the friction and further improve the mounting stability of the filter part 200. In addition, the edge of the side plate can be designed to be arc-shaped, which facilitates the installation process of the filter part 200 while reducing the wear of the filter part 200, further improving the mounting stability and service life.

[0092] Referring to Figures 1 to 5 , the frame 110 is provided with a guide 114 inside the cavity 111, and the tray 120 is correspondingly provided with a sliding part 1215. The sliding part 1215 is arranged on the side wall of the annular frame 121 facing the frame 110, and the sliding part 1215 is slidingly connected to the guide 114 to facilitate the installation or removal of the tray 120 to the frame 110. The arrangement of the guide 114 and the sliding part 1215 makes the installation and removal process of the tray 120 more smooth, reduces the operation difficulty, and at the same time ensures the accurate alignment of the tray 120 and the frame 110, further improving the stability and service life of the overall structure.

[0093] Specifically, when it is necessary to install or replace the filter part 200, the user can easily slide the tray 120 into or out of the frame 110 along the guide 114, reducing the need for manual adjustment and positioning. The guide 114 includes but is not limited to guide rails, sliding grooves and other structures, and the sliding part 1215 can be a sliding block or a roller.

[0094] To reduce the design difficulty and manufacturing cost of the shell assembly 100, the guide 114 can also be part of the frame 110 itself, and the guide structure can be directly punched out on the frame 110 by adopting stamping forming, sheet metal forming and other methods, which is curved outward relative to the frame 110 itself along the second direction Y. The end of the annular frame 121 away from the annular stopper 122 can directly abut against the guide structure, thereby realizing the guide function. This not only simplifies the production process, but also maintains the structural strength, ensures the stability and reliability of the tray 120 during sliding, and further improves the economy and practicality of the overall device.

[0095] Referring to Figure 3Specifically, the guiding member 114 is provided with a receiving portion 1141 and a sealing portion 1142 at an end away from the annular baffle 122. The receiving portion 1141 is protruded in a direction perpendicular to the first direction X, and the receiving portion 1141 is close to the annular baffle 122 and can receive the sliding member 1215. The sealing portion 1142 is connected to an end of the receiving portion 1141 close to the filter portion 200, and an end of the sealing portion 1142 away from the receiving portion 1141 is inclined towards the filter portion 200 and can abut against a side wall of the filter portion 200 arranged opposite in the second direction Y. Thus, when the filter portion 200 is installed on the tray 120 and the tray 120 is arranged in the frame 110, the sealing portion 1142 can further seal the tray 120 and the frame 110, so as to prevent untreated air from flowing to the air outlet 113 through a gap between the tray 120 and the frame 110, thereby improving the filtering effect.

[0096] In some embodiments, the guiding member 114 is arranged on both sides of the accommodating cavity 111 opposite in the second direction Y and extends in the first direction X. The tray 120 is provided with sliding members 1215 on both sides opposite in the second direction Y, and the sliding members 1215 are movably connected to the guiding member 114, so that the tray 120 can move relative to the frame 110 in the first direction X under the action of the sliding members 1215. Thus, at least part of the tray 120 can exit the accommodating cavity 111 from the air inlet 112 or the air outlet 113, facilitating quick replacement of the filter portion 200.

[0097] In other embodiments, referring to Figure 4 , the guiding member 114 is arranged on both sides of the accommodating cavity 111 opposite in the second direction Y and extends in the third direction Z. The frame 110 is provided with an outlet 115 on one side in the third direction Z, and the tray 120 is provided with sliding members 1215 on both sides opposite in the second direction Y, and the sliding members 1215 are movably connected to the guiding member 114, so that the tray 120 can move relative to the frame 110 in the third direction Z under the action of the sliding members 1215. Thus, at least part of the tray 120 can exit the accommodating cavity 111 from the outlet 115, realizing convenient replacement of the filter portion 200.

[0098] Referring to Figures 1 to 3 , the second aspect of the utility model further provides a filter module 10, which comprises the shell assembly 100 described in any of the above embodiments and at least one filter portion 200. The filter portion 200 is arranged in the accommodating cavity 111 and is fixed by the annular frame 121 and the annular baffle 122 and the like, so as to ensure smoothness of air flow and high efficiency of filtering effect.

[0099] The tray 120 comprises a ring-shaped frame 121 and a ring-shaped baffle 122, which are used to fix the position of the filter part 200 and provide sealing support. The ring-shaped frame 121 extends along the first direction X around the axis of the frame body 110, while the ring-shaped baffle 122 extends perpendicularly to the first direction X and is connected to the ring-shaped frame 121 at one end close to the air outlet 113. This not only ensures the stable installation of the filter part 200, but also prevents the leakage of unfiltered air, thereby improving the filtering efficiency of the overall system. Specifically, when the filter part 200 is placed in the tray 120, the sidewall of the ring-shaped baffle 122 away from the air outlet 113 will tightly abut the edge of the side of the filter part 200 facing the air outlet 113, thereby forming an effective sealing structure.

[0100] In some embodiments, in order to further improve the filtering effect and the flexibility of the system, multiple filter parts 200 can be integrated in the housing assembly 100. Each filter part 200 can be selected according to the specific air treatment requirements, and different types and functions can be selected. These filter parts 200 can be used independently or in combination to achieve multi-stage filtration and meet the air purification requirements in different environments.

[0101] In view of the improvement of the housing assembly 100, the filter module 10 in the present application has the technical effects of the housing assembly 100 in any of the above embodiments, which will not be repeated here.

[0102] Please refer to Figure 11 The third aspect of the present application also provides an air handling unit 1, which comprises the filter module 10 described in any of the above embodiments. The air handling unit 1 further comprises a heat exchange module 20 and an air supply module 30. The filter module 10 is used to purify the air entering the air handling unit 1, remove large particles of dust and other impurities, and provide a clean basis for subsequent processing steps. The heat exchange module 20 exchanges heat with the air to adjust the air temperature to meet the required comfort or process requirements. The air supply module 30 drives the air to flow through the heat exchange module 20 and the filter module 10, ensuring that the entire system can operate efficiently.

[0103] Specifically, the air first enters the cavity 111 through the housing assembly 100 in the filter module 10, where it is effectively purified by the filter part 200. The purified air then enters the heat exchange module 20, where the temperature is adjusted through a heat exchange process. Finally, the purified and temperature-adjusted air is pushed by the air supply module 30 and distributed to the designated area.

[0104] In view of the improvement of the housing assembly 100, the air handling unit 1 in the present application has the technical effects of the housing assembly 100 in any of the above embodiments, which will not be repeated here.
