[0047] For example, refer to Figure 1As shown, the volute 11 includes a first volute 111 and a second volute 112, which are arranged along the thickness direction of the partition 12 and are detachably connected, and the first volute 111 and the second volute 112 are suitable for defining an installation space, and the partition 12 is used to be installed in the installation space to be arranged between the first volute 111 and the second volute 112.

[0049] In some embodiments of the present invention, the partition 12 has a surrounding portion 122 disposed around the motor 21, and the surrounding portion 122 is connected to the first volute 111 through a fastener. Figure 3 , Figure 6 and Figure 7 As shown, a surrounding portion 122 may be provided on the partition 12, the surrounding portion 122 is arranged around the motor 21, a plurality of mounting through holes are provided on the surrounding portion 122, and the plurality of mounting through holes are arranged at intervals along the circumference of the surrounding portion 122, and a plurality of connecting holes may be provided on the first volute 111, the plurality of connecting holes are arranged in a one-to-one correspondence with the plurality of mounting through holes, and fasteners may be passed through the mounting through holes and connected to the corresponding connecting holes to fix the partition 12 on the first volute 111.

Through the above configuration, the limiting effect of the partition 12 and the first volute 111 on the motor 21 may be improved, and the installation stability of the motor 21 may be improved.

[0050] In some embodiments of the present invention, the edge of the partition 12 has a snap-fit ​​structure 123 that snaps into place with the first volute 111. Figure 3 , Figure 6 and Figure 7 As shown, a plurality of snap-fit ​​structures 123 may be provided on the edge of the partition 12, and the plurality of snap-fit ​​structures 123 are arranged at intervals along the edge of the partition 12, and the snap-fit ​​structures 123 are used to snap-fit ​​with the first volute 111 to fix the edge of the partition 12 on the first volute 111. Exemplarily, the snap-fit ​​structure 123 may be configured as a buckle, which is protruding toward the first volute 111, and a corresponding slot is provided on the first volute 111, and the buckle is snap-fitted and connected with the slot.

In addition, when the partition 12 is provided with both the surrounding portion 122 and the clamping structure 123, the surrounding portion 122 and the clamping structure 123 can be connected to the first volute 111 from different positions of the partition 12, which greatly improves the installation stability between the partition 12 and the first volute 111.

[0052] In some embodiments of the present invention, Figure 3 As shown, a partition plate 12 may be arranged to be accommodated inside the housing cavity of the first volute 111, and the first volute 111 may be arranged to be assembled and connected with the second volute 112. In a specific installation process, the partition plate 12 may be installed in the housing cavity of the first volute 111, and then the first volute 111 may be connected with the second volute 112, so as to install the partition plate 12 between the first volute 111 and the second volute 112.

[0053] Through the above arrangement, the difficulty of assembling the fresh air module 100 can be reduced, the fitting clearance can be reduced, the sealing difficulty of the volute 11 can be reduced, and the sealing performance of the volute 11 can be improved.

[0054] In some embodiments of the present invention, the volute 11 is a centrifugal volute, and the shell wall of the second volute 112 on one side away from the partition 12 forms an air inlet 1121. The fresh air module 100 includes a purification component 3 arranged upstream of the air inlet 1121. The first volute 111 includes a first air outlet diffuser section 1111, and the second volute 112 includes a second air outlet diffuser section 1122. An air outlet duct 15 is formed between the first air outlet diffuser section 1111 and the second air outlet diffuser section 1122.

[0055] For example, refer to Figure 1-Figure 5 As shown, the volute 11 can be constructed as a centrifugal volute, the air outlet 16 is arranged on the radial outer side of the wind wheel 22, and the air inlet 1121 is arranged axially opposite to the wind wheel 22, that is, the shell wall of the second volute 112 away from the partition 12 is formed with the air inlet 1121. Among them, the fresh air module 100 also includes a purification component 3, which can be constructed as a HEPA net. The purification component 3 is installed on the side of the second volute 112 away from the first volute 111 and located upstream of the air inlet 1121. The purification component 3 is used to purify the fresh air flow flowing into the air inlet 1121 to improve the quality of the fresh air.

[0056] At the same time, the first volute 111 can be provided with a first air outlet diffuser section 1111, and the second volute 112 can be provided with a second air outlet diffuser section 1122. The first air outlet diffuser section 1111 and the second air outlet diffuser section 1122 are arranged relative to each other along the thickness direction of the partition 12 and form an air outlet duct 15. The air outlet duct 15 is located radially outside the air inlet 1121 and is connected to the air outlet 16. The air outlet duct 15 is used to guide the fresh air flow in the second cavity 14 so that the fresh air flow can flow out stably from the air outlet 16.

[0057] Through the above arrangement, the space of the volute 11 can be fully utilized, which is beneficial to reducing the overall size of the volute 11 and facilitating the processing of the first volute 111 and the second volute 112, thereby improving the practicality of the fresh air module 100.

[0058] In some embodiments of the present invention, the shell cavity shape of the first volute 111 and the shell cavity shape of the second volute 112 are consistent with the contour shape of the partition 12. The partition 12 includes a noise reduction portion 124 arranged in the air outlet duct 15. There is a spacing space 151 between the noise reduction portion 124 and the first air outlet diffuser section 1111. A noise reduction hole 1241 connected to the spacing space 151 is formed on the noise reduction portion 124.

[0059] For example, refer to Figure 1-Figure 6 As shown, the shell cavity shape of the first volute 111 and the shell cavity shape of the second volute 112 can be set to be consistent with the contour shape of the partition 12, so that the two parts of the air outlet duct 15 located on both sides of the partition 12 along the thickness direction (i.e., the interval space 151 and the air outlet space 152 described below) can have the same structure.

[0060] The partition plate 12 may include a noise reduction portion 124, which is disposed in the air outlet duct 15, and a spacing space 151 is defined between the noise reduction portion 124 and the first air outlet diffuser section 1111, and an air outlet space 152 is defined between the noise reduction portion 124 and the second air outlet diffuser section 1122, and the air outlet space 152 is connected to the air outlet 16. The noise reduction portion 124 is formed with a noise reduction hole 1241, and the noise reduction hole 1241 is used to connect the spacing space 151 with the air outlet space 152.

[0061] Exemplarily, the partition space 151 and the noise reduction hole 1241 can be arranged to form a Helmholtz resonance cavity so that the noise in the air outlet space 152 can flow into the partition space 151 for noise reduction; or, a sound-absorbing material, such as sound-absorbing foam, etc., can be installed in the partition space 151 so that the noise in the air outlet space 152 can flow into the partition space 151 and be reduced by the sound-absorbing material.

[0062] Through the above arrangement, the partition space 151 can fully reduce the noise of the air outlet space 152, thereby achieving further noise reduction, which is beneficial to reducing the overall noise of the fresh air module 100 and improving the practicality of the fresh air module 100.

[0063] In some embodiments of the utility model, the partition 12 has a protruding structure 125 protruding toward the second cavity 14, and a side of the protruding structure 125 facing the first cavity 13 forms an avoidance groove 1251, which is matched with the motor 21 to accommodate at least part of the motor 21.

A avoidance groove 1251 is formed on the side of the protruding structure 125 facing the first cavity 13, and the avoidance groove 1251 is matched with the end of the motor 21 facing the second cavity 14, so that the end of the motor 21 facing the second cavity 14 can extend into the avoidance groove 1251 and cooperate with the partition 12 in positioning.

[0065] Through the above arrangement, during the installation process, the avoidance groove 1251 and the motor 21 can be initially positioned to reduce the difficulty of installing the partition 12 and improve the practicality of the fresh air module 100.

[0066] In some embodiments of the utility model, the partition 12 has a limiting rib 126 protruding toward the first cavity 13, and the motor 21 has a protrusion 212 protruding toward the partition 12. The protrusion 212 cooperates with the limiting rib 126 to limit the displacement of the motor 21 in the axial direction perpendicular to the rotating shaft 211.

[0067] For example, refer to Figure 3 and Figure 6 As shown, a limiting rib 126 can be provided on the partition 12, the limiting rib 126 protrudes toward the first cavity 13, there are multiple limiting ribs 126, and the multiple limiting ribs 126 are spaced apart along the axial direction of the rotating shaft 211. At the same time, a convex portion 212 can be provided on the side of the motor 21 facing the partition 12, the convex portion 212 protrudes toward the partition 12, and the convex portion 212 is used to extend between the multiple limiting ribs 126, so that the outer peripheral wall of the convex portion 212 can be respectively limited and matched with the multiple limiting ribs 126, so that the limiting ribs 126 can limit the displacement of the motor 21 in the axial direction perpendicular to the rotating shaft 211, thereby preventing the battery from moving. Through the above arrangement, the installation stability of the motor 21 can be improved, which is conducive to reducing the overall noise of the fresh air module 100.

[0068] In some embodiments of the present invention, the volute 11 includes a plurality of annular areas 113 concentrically arranged around the rotating shaft 211, and the partition plate 12 is provided with a plurality of resonance holes 121 spaced apart along the circumference of the rotating shaft 211 corresponding to each annular area 113, and the resonance holes 121 corresponding to adjacent annular areas 113 are staggered along the circumference of the rotating shaft 211.

[0069] For example, refer to Figure 5 and Figure 6 As shown, a first rib 114 is provided on the side of the volute 11 facing the first chamber 13. The first rib 114 is constructed in an annular shape and is arranged around the rotating shaft 211. There are multiple first ribs 114. The multiple first ribs 114 are arranged at intervals along the radial direction of the rotating shaft 211 and separate multiple annular areas 113. The multiple annular areas 113 are arranged concentrically around the rotating shaft 211.

[0070] At the same time, a plurality of second ribs 115 may be provided between two adjacent first ribs 114, the second ribs 115 extending in the radial direction, and the second ribs 115 are used to divide each annular region 113 into a plurality of resonance regions in the circumferential direction, and the volute 11 and the partition 12 are suitable for defining a resonance cavity 131 at the resonance region.

[0071] It should be noted that the resonance holes 121 corresponding to adjacent annular regions 113 may be staggered along the circumferential direction of the rotating shaft 211, so that the resonance cavities 131 corresponding to adjacent annular regions 113 may be staggered, so that the resonance cavities 131 of adjacent annular regions 113 may reduce noise from different circumferential positions.
