[0048] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0049] Combination Figure 1-8 As shown, this disclosure provides a housing assembly for a fresh air device, including a first half-shell 10 and a second half-shell 20.

[0050] Combination Figure 3-8 As shown, the first half-shell 10 has a concave first wall surface 311; the second half-shell 20 has a concave second wall surface 312. After the first half-shell 10 and the second half-shell 20 are assembled, they enclose and define a cylindrical inner cavity 30. The first half-shell 10 and the second half-shell 20 are detachably connected, and the inner wall surface 31 of the inner cavity includes the first wall surface 311 and the second wall surface 312.

[0051] The inner cavity 30 of the housing assembly is used to install the functional module 60 of the fresh air equipment, and also allows airflow to realize the supply and exhaust of fresh air from the equipment. The functional module 60 includes a fan 62, a heat exchange core 61, a filter, etc. Both ends of the cylindrical inner cavity 30 are formed with openings, allowing both ends of the cylindrical inner cavity 30 to be connected to the outside air.

[0052] The housing assembly for a fresh air system provided in this embodiment connects the indoor and outdoor environments via an inner cavity 30. The inner cavity 30 allows for the flow of exhaust and fresh air, and can also be used to install the functional modules of the fresh air system. The housing assembly adopts a split design, with a detachable connection between the first half-shell 10 and the second half-shell 20. This improves the efficiency of disassembly and installation of the functional modules 60, facilitating cleaning and maintenance. The functional modules 60 can be directly installed or removed by removing either the first or second half-shell. This not only effectively improves the convenience of disassembly and assembly but also reduces wear and tear during the process, thereby extending the service life of the functional modules 60.

[0053] Optionally, combined Figure 5 As shown, the first half-shell 10 and the second half-shell 20 are arranged opposite each other in the vertical direction about the axis of the inner cavity 30.

[0054] The axis of the inner cavity 30 refers to a straight line passing through the center of the inner cavity and extending along the axial direction of the inner cavity. The direction of the axis of the inner cavity 30 is as follows: Figure 5 As indicated by the arrow, the first half-shell 10 and the second half-shell 20 are positioned vertically opposite each other about the axis of the inner cavity 30, meaning they are located on opposite sides of the axis of the inner cavity 30. The first half-shell 10 and the second half-shell 20 provide vertical support and protection for the components within the inner cavity 30, while the connection point is horizontal. This facilitates not only disassembly and installation of the housing assembly but also provides stable structural support during the operation of the fresh air system. After removing the first half-shell 10, the second half-shell 20 provides stable support for the functional module 60 from below, preventing the functional module 60 from shaking or being damaged due to loss of support during installation or disassembly, thus improving the safety of the disassembly process. The first half-shell 10 and the second half-shell 20 can be designed with snap-fit, threaded connection, or other detachable fixed connection methods to prevent the housing assembly from loosening due to vibration or external forces.

[0055] Optionally, combined Figure 5-8 As shown, the first half-shell 10 is provided with a snap-fit ​​part 11, and the second half-shell 20 is provided with a snap-fit ​​mating part 21. The snap-fit ​​part 11 and the snap-fit ​​mating part 21 are engaged to make the first half-shell 10 and the second half-shell 20 fit together.

[0056] The snap-fit ​​method in which the snap-fit ​​part 11 and the snap-fit ​​mating part 21 cooperate can effectively simplify the installation and disassembly process of the first half shell 10 and the second half shell 20, thereby improving assembly efficiency.

[0057] Optionally, combined Figure 5-8 As shown, the snap-fit ​​part 11 is provided at the end of the first half shell 10 facing the second half shell 20; the snap-fit ​​mating part 21 is provided at the end of the second half shell 20 facing the first half shell 10.

[0058] This allows for quick alignment during the assembly of the first half-shell 10 and the second half-shell 20, reducing alignment errors during the assembly process and thus improving assembly efficiency.

[0059] Optionally, combined Figure 5-8 As shown, the snap-fit ​​part 11 includes a first snap-fit ​​111, and the snap-fit ​​mating part 21 includes a first snap-fit ​​hole 211. The first snap-fit ​​111 and the first snap-fit ​​hole 211 are engaged in a corresponding snap-fit ​​mating.

[0060] A first snap-fit ​​111 is provided on the first half-shell 10, and a first snap-fit ​​hole 211 is provided on the second half-shell 20. The first snap-fit ​​111 and the first snap-fit ​​hole 211 are correspondingly arranged. Through the snap-fit ​​engagement of the first snap-fit ​​111 and the first snap-fit ​​hole 211, a tight and stable connection can be achieved between the first half-shell 10 and the second half-shell 20. The snap-fit ​​structure of the first snap-fit ​​111 and the first snap-fit ​​hole 211 can effectively shorten the assembly and disassembly time.

[0061] Optionally, combined Figure 6 and Figure 7 As shown, the snap-fit ​​part 11 also includes a first snap-fit ​​groove 16, which is recessed into the outer wall surface of the first half shell 10, and a first snap fastener 111 is disposed in the first snap-fit ​​groove 16; the snap-fit ​​mating part 21 also includes a first snap-fit ​​protrusion 26, which extends from the second half shell 20 toward the first half shell 10, and a first snap hole 211 is disposed in the first snap-fit ​​protrusion 26; wherein, when the first snap-fit ​​protrusion 26 is snapped into the first snap-fit ​​groove 16, the first snap fastener 111 can be snapped into the first snap hole 211.

[0062] When the first protrusion 26 is engaged in the first slot 16, the first buckle 111 can be engaged in the first hole 211, so that the engagement part 11 and the engagement mating part 21 form a double engagement structure, which can effectively improve the connection strength and stability between the engagement part 11 and the engagement mating part 21.

[0063] Optionally, combined Figure 5-8 As shown, the snap-fit ​​part 11 includes a second snap hole 112, and the snap-fit ​​mating part 21 includes a second snap buckle 212, which is engaged with the second snap hole 112.

[0064] A second locking hole 112 is provided on the first half-shell 10, and a second locking buckle 212 is provided on the second half-shell 20. The second locking hole 112 and the second locking buckle 212 are correspondingly arranged. Through the locking and engaging of the second locking hole 112 and the second locking buckle 212, a tight and stable connection can be achieved between the first half-shell 10 and the second half-shell 20. The locking and engaging structure of the second locking hole 112 and the second locking buckle 212 can effectively shorten the assembly and disassembly time.

[0065] Optionally, combined Figure 6 and Figure 7 As shown, the latching part 11 also includes a second latching protrusion 17, which extends from the first half shell 10 toward the second half shell 20, and a second latching hole 112 is provided in the second latching protrusion 17; the latching mating part 21 also includes a second latching groove 27, which is recessed in the outer wall surface of the second half shell 20, and a second latch 212 is provided in the second latching groove 27; wherein, when the second latching protrusion 17 is engaged in the second latching groove 27, the second latch 212 can be engaged in the second latching hole 112.

[0066] When the second protrusion 17 is engaged in the second slot 27, the second buckle 212 can be engaged in the second hole 112, so that the engagement part 11 and the engagement mating part 21 form a double engagement structure, which can effectively improve the connection strength and stability between the engagement part 11 and the engagement mating part 21.

[0067] This application takes as an example a snap-fit ​​part 11 including a first snap fastener 111, a snap-fit ​​mating part 21 including a first snap hole 211, the first snap fastener 111 and the first snap hole 211 being snap-fit ​​mated accordingly; and a snap-fit ​​part 11 including a second snap hole 112, a snap-fit ​​mating part 21 including a second snap fastener 212, the second snap fastener 212 and the second snap hole 112 being snap-fit ​​mated accordingly.

[0068] A first latch 111 and a second latching hole 112 are provided in the first half-shell 10, and a first latching hole 211 and a second latch 212 are correspondingly provided in the second half-shell 20. The cooperation between the first latch 111 and the first latching hole 211, and between the second latch 212 and the second latching hole 112, can form a multi-point connection between the first half-shell 10 and the second half-shell 20, which can effectively enhance the connection strength between the first half-shell 10 and the second half-shell 20. This multi-point connection support structure can effectively disperse stress and reduce structural damage caused by local stress concentration. At the same time, by providing latching parts 11 with different structures in the first half-shell 10 and latching mating parts 21 with different structures in the second half-shell 20, the stability of the connection between the first half-shell 10 and the second half-shell 20 can be effectively improved through the alternating cooperation of different latching structures.

[0069] Optionally, combined Figure 5-7 As shown, the snap-fit ​​part 11 includes a plurality of first snaps 111 and a plurality of second snap holes 112, and the snap-fit ​​mating part 21 includes a plurality of first snap holes 211 and a plurality of second snaps 212. The first snaps 111 and the second snap holes 112 are disposed opposite to each other about the axis of the inner cavity at both ends of the first half shell 10, and the first snaps 111 and the second snap holes 112 at each end are alternately arranged along the axis of the inner cavity; the first snap holes 211 and the second snaps 212 are disposed opposite to each other about the axis of the inner cavity at both ends of the second half shell 20, and the first snap holes 211 and the second snap holes 212 at each end are alternately arranged along the axis of the inner cavity.

[0070] The first latch 111 and the second latch hole 112 are positioned opposite each other at both ends of the first half-shell 10 about the axis of the inner cavity. This means that the first latch 111 is located at the first end of the first half-shell 10 about the axis of the inner cavity, and the second latch hole 112 is correspondingly located at the second end of the first half-shell 10 about the axis of the inner cavity. This results in different locking structures at the corresponding positions at both ends of the first half-shell 10 about the axis of the inner cavity. Furthermore, the first latch 111 and the second latch hole 112 at each end are alternately arranged along the axial direction of the inner cavity. The first latch hole and the second latch of the second half-shell 20 are correspondingly arranged to the first latch 111 and the second latch hole 112 of the first half-shell. This effectively enhances the connection stability between the first and second half-shells.

[0071] Optionally, combined Figure 6 and Figure 7 As shown, the first half-shell 10 and the second half-shell 20 are arranged rotationally symmetrically about the axis of the inner cavity 30.

[0072] After the first half-shell 10 is rotated 180° around the axis of the inner cavity 30, it can completely overlap with the second half-shell 20. With the first half-shell 10 having a snap-fit ​​part 11 and the second half-shell 20 having a snap-fit ​​mating part 21, the entire structure, including the snap-fit ​​part 11 and the snap-fit ​​mating part 21, can overlap after the first half-shell 10 is rotated 180° around the axis of the inner cavity 30. Three mutually perpendicular constraints can be formed between the first half-shell 10 and the second half-shell 20, making the connection between them more robust. Since the first half-shell 10 and the second half-shell 20 are rotationally symmetrical about the axis of the inner cavity 30, they have the same structure, only in opposite directions. This allows the first half-shell 10 and the second half-shell 20 to be produced using the same mold, effectively reducing the manufacturing cost of the shell assembly.

[0073] Optionally, combined Figure 5-7 As shown, the inner wall of the first half-shell 10 is provided with a first wiring groove 12; and / or, the inner wall of the second half-shell 20 is provided with a second wiring groove 22.

[0074] By providing a first wiring trough 12 on the inner wall of the first half-shell 10 and / or a second wiring trough 22 on the inner wall of the second half-shell 20, a dedicated wiring channel can be provided for the electrical wiring of the fresh air equipment, avoiding mutual interference between the wiring harness 80 and the functional module 60. This also improves the space utilization of the housing components and enhances the aesthetics.

[0075] Optionally, combined Figure 4-6 As shown, the inner wall of the first half shell 10 is provided with a first limiting rib 13. The first limiting rib 13 extends circumferentially along the first half shell 10 to divide the inner cavity 30 into multiple sub-cavities along the axial direction of the inner cavity 30. The multiple sub-cavities are spaced apart from each other and connected to each other, and are used to install different functional modules 60 of the fresh air equipment.

[0076] Zhou Xiangru, the first half-shell 10 Figure 6 As indicated by the middle arrow. By providing a first limiting rib 13 on the inner wall of the first half-shell 10, extending circumferentially along the first half-shell 10, the inner cavity 30 can be divided into multiple spaced and interconnected sub-cavities. When a first wiring groove 12 is provided on the inner wall of the first half-shell 10, the first wiring groove 12 extends along the axial direction of the inner cavity 30 and passes through the first limiting rib 13.

[0077] Optionally, combined Figure 4 , Figure 5 and Figure 7As shown, the inner wall of the second half shell 20 is provided with a second limiting rib 23. The second limiting rib 23 extends along the circumference of the second half shell 20 to divide the inner cavity 30 into multiple sub-cavities along the axial direction of the inner cavity 30. The multiple sub-cavities are spaced apart from each other and connected to each other, and are used to install different functional modules 60 of the fresh air equipment.

[0078] The second half-shell 20 Zhou Xiangru Figure 7 As indicated by the middle arrow. By providing a second limiting rib 23 on the inner wall of the second half-shell 20, extending circumferentially along the second half-shell 20, the inner cavity 30 can be divided into multiple spaced-apart and interconnected sub-cavities. When a second wiring groove 22 is provided on the inner wall of the second half-shell 20, the second wiring groove 22 extends along the axial direction of the inner cavity 30 and passes through the second limiting rib 23.

[0079] Installing different functional modules 60, such as the fan 62, heat exchange core 61, and filter screen, into different sub-cavities effectively reduces mutual interference between them. The first limiting rib 13 and the second limiting rib 23 have simple structures, are easy to manufacture, and also enhance the structural strength of the first half-shell 10 and the second half-shell 20. There can be one or more first limiting ribs 13, with two spaced sub-cavities formed on both sides of each first limiting rib 13. The number of first limiting ribs 13 can be set according to the number of functional modules 60. Similarly, there can be one or more second limiting ribs 23, with two spaced sub-cavities formed on both sides of each second limiting rib 23. The number of second limiting ribs 23 can be determined according to the number of functional modules 60.

[0080] Optionally, combined Figure 5 As shown, the first limiting rib 13 and the second limiting rib 23 are respectively provided.

[0081] The number of first limiting ribs 13 and second limiting ribs 23 is the same, and their positions correspond. In this way, each first limiting rib 13 and each second limiting rib 23 can surround and form a complete limiting rib structure around the circumference of the inner cavity 30, effectively improving the independence between multiple sub-cavities.

[0082] Optionally, combined Figure 3-5 As shown, the housing assembly for the fresh air equipment also includes a fastener 40, which surrounds the outside of the first half-shell 10 and the second half-shell 20 to secure the first half-shell 10 and the second half-shell 20.

[0083] The fastener 40 effectively enhances the connection between the first half-shell 10 and the second half-shell 20, preventing the shell assembly from loosening due to external forces. This also improves the sealing of the shell assembly, preventing or reducing the leakage of air from the inner cavity 30 through the connection gap between the first half-shell 10 and the second half-shell 20, thereby improving the energy efficiency of the fresh air equipment.

[0084] Optionally, combined Figure 5 As shown, there are multiple fasteners 40, which are arranged along the axial direction of the inner cavity 30.

[0085] By arranging multiple fasteners 40 along the axial direction of the inner cavity 30, the fastening effect on the first half-shell 10 and the second half-shell 20 can be improved.

[0086] Optionally, fastener 40 includes a rubber clamp.

[0087] The rubber clamp has high elasticity, which allows it to fit tightly against the outer walls of the first half-shell 10 and the second half-shell 20 during installation, providing a stable fastening force.

[0088] Optionally, combined Figure 5-7 As shown, the outer wall of the first half-shell 10 is provided with a first limiting groove 14, which extends circumferentially along the first half-shell 10; the outer wall of the second half-shell 20 is provided with a second limiting groove 24, which extends circumferentially along the second half-shell 20; wherein the first limiting groove 14 and the second limiting groove 24 are correspondingly provided, and the fastener 40 is embedded in the first limiting groove 14 and the second limiting groove 24.

[0089] The first limiting groove 14 and the second limiting groove provide a stable installation position for the fastener 40, effectively preventing displacement or loosening of the fastener 40. The first limiting groove 14 extends circumferentially along the first half-shell 10, and the second limiting groove 24 extends circumferentially along the second half-shell 20. The first limiting groove 14 and the second limiting groove 24 are correspondingly arranged, which allows for better engagement with the fastener 40 and improves its stability. The fastener 40 is also embedded in the first limiting groove 14 and the second limiting groove 24, further enhancing the seal between the first half-shell 10 and the second half-shell 20.

[0090] Optionally, combined Figure 1 and Figure 4 As shown, the housing assembly also includes an outer shell 50, which is fitted over the outer side of the first half-shell 10 and the second half-shell 20.

[0091] The outer casing 50 provides protection for the first half-shell 10, the second half-shell 20, and the functional module 60 located in the inner cavity 30. When the fresh air system is a through-wall type, the outer casing 50 effectively prevents moisture, dust, or foreign objects from the wall from entering the interior of the fresh air system, thus ensuring the overall stability of the system. The outer casing 50 fits tightly with the first half-shell 10 and the second half-shell 20, improving the airtightness of the fresh air system.

[0092] Combination Figure 1-4As shown, this disclosure provides a fresh air device, including a housing assembly for the fresh air device as described in any of the above-disclosed embodiments, wherein the inner cavity 30 of the housing assembly is used to communicate with the indoor environment and the outdoor environment.

[0093] The fresh air equipment provided in this disclosure includes the housing assembly for fresh air equipment as described in any of the above-disclosed embodiments, and therefore has all the beneficial effects of the housing assembly for fresh air equipment as described in any of the above-disclosed embodiments, which will not be repeated here.

[0094] The fresh air equipment provided in this embodiment can be a through-wall fresh air unit.

[0095] Optionally, combined Figure 3 , Figure 4 and Figure 8 As shown, the functional module 60 of the fresh air equipment includes a heat exchange core 61 and a fan 62. The heat exchange core 61 is located in the inner cavity 30; the fan 62 is located in the inner cavity 30, and the fan 62 and the heat exchange core 61 are arranged along the axial direction of the inner cavity 30. In the case where the inner wall of the first half-shell 10 is provided with a first limiting rib 13 extending circumferentially along the first half-shell 10 and / or the inner wall of the second half-shell 20 is provided with a second limiting rib 23 extending circumferentially along the second half-shell 20, so that the inner cavity 30 is divided into multiple intermittent and interconnected sub-cavities, the heat exchange core 61 and the fan 62 are located in different sub-cavities.

[0096] The heat exchange core 61 is used to store heat or cold in the exhaust airflow of the fresh air system and transfer the stored heat or cold to the fresh airflow. The heat exchange core 61 can be a ceramic heat exchange core body. The fan 62 is used to guide the exhaust airflow through the inner cavity 30 to be discharged to the outdoor environment and to guide the fresh airflow through the inner cavity 30 to be delivered to the indoor environment. The fan 62 can be a reversible fan. The heat exchange core 61 and the fan 62 are located in different sub-cavities, which can improve the independence between the heat exchange core 61 and the fan 62, reduce the mutual influence between the heat exchange core 61 and the fan 62, and facilitate individual maintenance and replacement. There can be one or more heat exchange cores 61 and one or more fans 62, with each heat exchange core 61 and each fan 62 installed in a different sub-cavity.

[0097] Optionally, combined Figure 1 and Figure 2As shown, the fresh air equipment also includes an indoor panel 70, which is connected to the first half-shell 10 and the second half-shell 20 and located at one end of the inner cavity 30. The first half-shell 10 is provided with a first positioning part 15, which cooperates with the indoor panel 70 to position the first half-shell 10 on the indoor panel 70. The second half-shell 20 is provided with a second positioning part 25, which cooperates with the indoor panel 70 to position the second half-shell 20 on the indoor panel 70. The first positioning part 15 and the second positioning part 25 are different positioning structures.

[0098] The cooperation between the first positioning part 15 and the second positioning part 25 and the indoor panel 70 provides additional support for the first half-shell 10 and the second half-shell 20, enhancing the structural strength of the entire fresh air system. The cooperation between the first positioning part 15 and the second positioning part 25 and the indoor panel 70 also improves the alignment accuracy of the first half-shell 10 and the second half-shell 20 during installation. As different positioning structures, the first positioning part 15 and the second positioning part 25 prevent the first half-shell 10 and the second half-shell 20 from being installed backwards, thereby improving assembly efficiency. The first positioning part 15 and the second positioning part 25 may have different structures, shapes, or other appearance features. When the first half-shell 10 includes the first positioning part 15 and the second half-shell 20 includes the second positioning part 25, it can be configured such that after the first half-shell 10 is rotated 180° around the axis of the inner cavity 30, the structural parts of the first half-shell 10 and the second half-shell 20, excluding the first positioning part 15 and the second positioning part 25, can overlap.

[0099] Optionally, combined Figure 5 As shown, the first positioning part 15 is a first positioning block 151 of a first shape, and the second positioning part 25 is a second positioning block 251 of a second shape.

[0100] By designing first positioning blocks 151 and second positioning blocks 251 with different shapes, the first half-shell 10 and the second half-shell 20 can be intuitively distinguished, allowing users to quickly identify the first half-shell 10 and the second half-shell 20 during assembly. The first shape can be a triangle, and the second shape can be a quadrilateral.

[0101] Optionally, combined Figure 1 and Figure 2 As shown, the indoor panel 70 is provided with a fixing part 71 for fixing the wire harness 80 to the indoor panel 70.

[0102] The wiring harness 80 of the functional module 60 extending from the inner cavity 30 is fixed to the indoor panel 70 by the fixing part 71, which can improve the neatness of the wiring harness 80.

[0103] Optionally, combined Figure 1 and Figure 2As shown, the fixing part 71 includes a fixing piece 711, and the wire harness 80 is clamped between the fixing piece 711 and the interior panel 70. The fixing piece 711 is fixed to the interior panel 70 by screws.

[0104] A wiring space is formed between the fixing plate 711 and the indoor panel 70. The wire harness 80 passes through the wiring space and the fixing plate 711 is fixed to the indoor panel 70 by screws, which can provide stable support and prevent the wire harness 80 from loosening during equipment operation.

[0105] Optionally, combined Figure 1 and Figure 2 As shown, the fixing part 71 includes a claw 712, which has a clamping space, through which the wire harness 80 can be inserted and fixed.

[0106] The clamping space of the claw 712 can tightly secure the wire harness 80, reducing space occupation. The structure of the claw 712 allows for quick installation and removal of the wire harness 80 without the need for tools, which can significantly improve the fixing efficiency of the wire harness 80.
