[0036] Embodiments of the present invention are described in detail below.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following is for reference. Figures 1-11 A rotary wheel assembly 100 according to an embodiment of the present invention is described.

[0040] like Figures 1-11 As shown, the rotary wheel assembly 100 according to an embodiment of the present invention includes: a first frame 10, a second frame 20, and an adsorption member 30. The second frame 20 is disposed on the first frame 10 so that the first frame 10 and the second frame 20 cooperate with each other. The adsorption member 30 can be installed between the first frame 10 and the second frame 20 to prevent the adsorption member 30 from falling out of the rotary wheel assembly 100. The first frame 10 and the second frame 20 can be fixedly connected to facilitate fixing the adsorption member 30.

[0041] According to the embodiment of the present invention, the rotary wheel assembly 100 achieves a fixed connection between the first frame 10 and the second frame 20 through mutual cooperation. The adsorption member 30 can be directly fixed in the two frames without the need for fixing by means of glue, which simplifies the installation process and avoids glue overflow affecting the appearance and performance of the rotary wheel assembly 100. While not affecting the performance of the rotary wheel assembly 100, it shortens the assembly time, facilitates assembly, and thus improves production efficiency.

[0042] In some examples, the fixed connection between the first frame 10 and the second frame 20 can be a snap-fit ​​connection or other similar connection method, which is preferable for easy and reliable fixing.

[0043] According to some embodiments of the present invention, the first frame 10 includes: an inner frame 14, an outer frame 12, and a plurality of partitions 13. The outer frame 12 is disposed outside the inner frame 14. The plurality of partitions 13 are spaced apart between the inner frame 14 and the outer frame 12, and the two ends of each partition 13 are respectively connected to the inner frame 14 and the outer frame 12. The partitions 13 divide the space between the inner frame 14 and the outer frame 12 into a plurality of first spaces 11. At least a portion of the adsorption member 30 can be arranged in the first space 11, which is beneficial for fixing the adsorption member 30. The inner frame 14 may have a connecting structure, and the outer frame 12 may also have a connecting structure. The inner frame 14 and the outer frame 12 may have a connecting structure at the same time. The connecting structure is located outside the first space 11 to avoid interference with the installation of the adsorption member 30. The connecting structure can fix two adjacent outer frames 12, and the connecting structure can also fix two adjacent inner frames 14. That is, the connecting structure cooperates with the second frame 20 to improve the fixing effect between the first frame 10 and the second frame 20.

[0044] In some examples, the first frame 10 defines a first space 11 and a first air vent 15. The number of first air vents 15 is the same as the number of first spaces 11. The first air vents 15 are interconnected with the corresponding first spaces 11. There can be one or more first spaces 11. The second frame 20 defines a second space 21 and a second air vent 22. The number of second air vents 22 is the same as the number of second spaces 21. The second air vents 22 are interconnected with the corresponding second spaces 21. There can be one or more second spaces 21. The number and shape of the second spaces 21 correspond to the number and shape of the first spaces 11, so that one second space 21 corresponds to one first space 11 to form an installation space. The adsorption component 30 corresponds to the installation space, so that the adsorption component 30 can be installed in the installation space.

[0045] The first frame 10 and the second frame 20 are snapped together to achieve a fixed connection between the first frame 10 and the second frame 20, thereby fixing the adsorption component 30 on the two frames and realizing the installation and fixation of the adsorption component 30 without the need for additional processing of the adsorption component 30.

[0046] like Figure 4 As shown, in some examples, the first air vent 15 and the second air vent 22 are located on both sides of the installation space (e.g., Figure 4 As shown on the upper and lower sides), the first air inlet 15 and the second air inlet 22 cooperate with each other, so that air can flow in a straight line through the installation space, improving the air passage efficiency. In addition, the adsorption element 30 here can be a molecular sieve or a material with adsorption function such as silica gel.

[0047] like Figure 4 , Figure 6 and Figure 10 As shown, in some examples, the first frame 10 may have multiple first spaces 11, which are arranged at intervals along the outer periphery of the first frame 10. The second frame 20 may have multiple second spaces 21, which are arranged at intervals along the outer periphery of the second frame 20. The second frame 20 may be installed above the first frame 10, such that the multiple first spaces 11 and the multiple second spaces 21 can correspond to each other in position, and the number of first spaces 11 and the number of second spaces 21 are the same. The shape of the first space 11 is the same as the shape of the second space 21, and the size of the first space 11 is the same as the size of the second space 21, so that each first space 11 can cooperate with the corresponding second space 21, which facilitates the installation of the adsorption member 30.

[0048] When the first frame 10 and the second frame 20 are not yet snapped together, the adsorption member 30 can be embedded into the first space 11 from top to bottom along the central axis of the rotating wheel assembly 100. Here, the adsorption member 30 can be interference-fitted with the wall of the first space 11. Then, the second frame 20 is pressed down at the snap-fit ​​position, and the adsorption member 30 can also be embedded into the second space 21 from bottom to top along the central axis of the rotating wheel assembly 100. Here, the adsorption member 30 can be interference-fitted with the wall of the second space 21. Thus, the two frames can be snapped together to install and fix the adsorption member 30 in the installation space. At this time, the adsorption member 30 can be interference-fitted with the wall of the installation space, ensuring the stability of the adsorption member 30 and preventing the adsorption member 30 from shaking and falling out in the installation space.

[0049] According to some embodiments of the present invention, the adsorption member 30 can be interference-fitted with the first frame 10, and the adsorption member 30 can also be interference-fitted with the second frame 20. The adsorption member 30 can be interference-fitted with both the first frame 10 and the second frame 20 at the same time. Through the interference fit between the adsorption member 30 and the frame, the two frames can be fixedly connected to secure the adsorption member 30, thereby improving the fixing effect of the adsorption member 30 and preventing the adsorption member 30 from falling off.

[0050] According to some embodiments of the present invention, the cross-sectional dimensions of each first space 11 can gradually decrease from top to bottom along the vertical direction, so that when the adsorbent 30 is embedded in the first space 11, the adsorbent 30 is gradually pressed around its perimeter, and the adsorbent 30 can fit more tightly against the inner wall of the first frame 10, which is convenient for the placement of the adsorbent 30 and can ensure the reliability of the fixation of the adsorbent 30.

[0051] In some examples, the cross-sectional dimensions of each second space 21 can gradually decrease from bottom to top vertically. This allows the adsorbent 30 to be gradually compressed around its perimeter when it is embedded in the second space 21, enabling it to fit more tightly against the inner wall of the second frame 20. This facilitates placement of the adsorbent 30 and improves the frame's fixation effect, effectively preventing it from falling out. Furthermore, the gradual decrease in cross-sectional dimensions of both the first space 11 and the second space 21 allows both frames to apply pressure to the adsorbent 30 simultaneously during installation, further enhancing its fixation. Because the cross-sectional dimensions of the first space 11 and the second space 21 gradually decrease, the adsorbent 30 is gradually compressed around its perimeter during embedding, allowing it to fit tightly against the wall of the installation space, achieving adhesive-free fixation. This makes installation easier, prevents detachment after installation, and facilitates assembly.

[0052] like Figure 4 , Figure 6 and Figure 10 As shown, according to some embodiments of the present invention, the first frame 10 includes: an inner frame 14, an outer frame 12 and a plurality of partitions 13. The inner frame 14 and the outer frame 12 can each form an annulus. For example, the inner frame 14 and the outer frame 12 can each form a circular annulus or a square annulus. The outer frame 12 is disposed outside the inner frame 14, and the outer frame 12 and the inner frame 14 are arranged concentrically at intervals so that the rotating wheel assembly 100 can rotate along the center. The space between the outer frame 12 and the inner frame 14 is convenient for placing the adsorption member 30.

[0053] The partition 13 is disposed between the inner frame 14 and the outer frame 12. The two ends of each partition 13 are connected to the inner frame 14 and the outer frame 12 respectively. Multiple partitions 13 are arranged at intervals along a circumference. The partition 13 can divide the space between the inner frame 14 and the outer frame 12 into multiple first spaces 11, thereby allowing multiple adsorption components 30 to be placed in the first frame 10.

[0054] like Figures 1-11 As shown, in some examples, the inner side of the inner frame 14 may have a connecting structure, and the second frame 20 has a corresponding mating part. The inner frame 14 of the first frame 10 and the second frame 20 are fixedly connected by the connecting structure and the mating part engaging. Here, the connecting structure can be a hook 51 and the mating part can be a slot 52, or the connecting structure can be a slot 52 and the mating part can be a hook 51, or the connecting structure can include a hook 51 and a slot 52. That is, the inner frame 14 is provided with a hook 51 and a slot 52, and correspondingly, the second frame 20 is provided with a slot 52 and a hook 51.

[0055] The outer side of the outer frame 12 may also have a connecting structure, and the second frame 20 has a corresponding mating part. The outer frame 12 of the first frame 10 and the second frame 20 are fixedly connected by the connecting structure and the mating part engaging. Here, the connecting structure can be a hook 51 and the mating part can be a slot 52, or the connecting structure can be a slot 52 and the mating part can be a hook 51, or the connecting structure can include a hook 51 and a slot 52. That is, the outer frame 12 is provided with a hook 51 and a slot 52, and correspondingly, the second frame 20 is provided with a slot 52 and a hook 51.

[0056] In some examples, the inner side of the inner frame 14 and the outer side of the outer frame 12 can have a connecting structure. The connecting structure can be of the same type or two types that can be matched with each other. The two frames can be snapped together at multiple positions, which is beneficial for the uniform force between the two frames and prevents gaps from appearing at the connection between the two frames. While improving the fixing effect of the two frames, it also improves the stability and sealing of the wheel assembly 100 and can prevent air leakage at the connection.

[0057] like Figure 4 , Figure 6 and Figure 10 As shown, in some examples, multiple partitions 13 are arranged at equal intervals along the outer periphery of the rotating assembly 100, so that the shape and size of each first space 11 are the same, and the shape and size of each second space 21 are the same, which is convenient for processing. Of course, the size of the first space 11 between two adjacent partitions 13 can also be different, and the size and shape of the second space 21 and the adsorption member 30 can correspond to it.

[0058] In some examples, the cross-sectional dimensions of the partition 13 in the first frame 10 gradually increase from top to bottom along the vertical direction, such that the two sides of the partition 13 can form a second guide surface 131, and the extension direction of the second guide surface 131 is inclined to the axial direction of the wheel assembly 100 (e.g., Figure 4 (as shown in the vertical direction), thus making the cross-sectional area of ​​the first space 11 along the vertical direction (such as...) Figure 4 As shown in the top-to-bottom direction, the area gradually decreases. The adsorption element 30 is placed in any of the rotating wheel frames, and the other frame is pressed down according to the position of the connection structure. Since the cross-sectional area of ​​the first space 11 gradually decreases along the bottom, the two rotating wheel frames gradually press the adsorption element 30 together, which improves the fixing effect of the frame on the adsorption element 30.

[0059] like Figure 4 , Figure 10 and Figure 11 As shown, in some examples, in the first frame 10, a limiting part 16 is provided at the lower part of the inner frame 14, or at the lower part of the outer frame 12, or at the lower part of the partition 13. Alternatively, the limiting part 16 is formed at the lower part of any two structures. The first air vent 15 is located on the lower side of the first frame 10. The limiting part 16 protrudes into the inner side of the adjacent first space 11. Of course, the limiting part 16 can also be provided on the inner frame 14, the outer frame 12, and the partition 13 at the same time. The limiting part 16 surrounds the edge of the first air vent 15. The limiting part 16 can prevent the adsorbent 30 from falling out of the first air vent 15.

[0060] The number of limiting parts 16 can be multiple, and the multiple limiting parts 16 should be on the same horizontal plane to ensure that the limiting parts 16 effectively limit the various positions of the adsorption member 30.

[0061] In some examples, the inner surface of the outer frame 12 has a first guide surface 123, which gradually slopes towards the inner frame 14 in a direction away from the second frame 20. That is, the inner surface of the outer frame 12 gradually slopes inward from top to bottom, and the cross-sectional dimensions of the outer frame 12 in the first frame 10 gradually increase from top to bottom in the vertical direction. This allows the cross-sectional area of ​​the first space 11 to increase along the vertical direction (e.g., ...). Figure 4 As shown in the top-to-bottom direction, the area gradually decreases. The adsorption element 30 is placed in any of the rotating wheel frames, and the other frame is pressed down according to the position of the connection structure. Since the cross-sectional area of ​​the first space 11 gradually decreases along the bottom, the two rotating wheel frames gradually press the adsorption element 30 together, which improves the fixing effect of the frame on the adsorption element 30.

[0062] like Figure 4 , Figure 5 , Figure 9 and Figure 10As shown, in some examples, the second frame 20 is mounted above the first frame 10. On the first frame 10, the upper side of the outer frame 12 has an inner baffle 121 and an outer baffle 122. In the radial direction of the outer frame, the inner baffle 121 is located inside the outer baffle 122, that is, the inner baffle 121 is closer to the inner frame 14 than the outer baffle 122. The inner baffle 121 and the outer baffle 122 are arranged alternately along the circumference of the outer frame 12, that is, an outer baffle 122 is provided between two adjacent inner baffles 121, and an inner baffle 121 is provided between two adjacent outer baffles 122.

[0063] The second frame 20 has an outer frame 12 with the same structure as the first frame 10. When the first frame 10 and the second frame 20 cooperate with each other, the inner baffle 121 of the first frame 10 can cooperate with the outer baffle 122 of the second frame 20, so that the inner baffle 121 abuts against the inner side of the outer baffle 122. At the same time, the outer baffle 122 of the first frame 10 can cooperate with the inner baffle 121 of the second frame 20, so that the outer baffle 122 abuts against the inner side of the inner baffle 121. This can improve the sealing performance of the rotating wheel assembly 100, avoid air leakage at the connection, and ensure that air can only pass through the second air passage 22 from the first air passage 15, which is conducive to the adsorption component 30 and the air being in full contact.

[0064] In some examples, the mating surfaces of the inner baffle 121 and the outer baffle 122 can be inclined surfaces. The two baffles mate with each other through vertical surfaces, achieving a mating fit between the two frames. This helps prevent sharp corner contact, reduces wear, and improves the service life of the wheel assembly 100. Of course, the mating surfaces of the inner baffle 121 and the outer baffle 122 can also be vertical surfaces to facilitate manufacturing.

[0065] like Figure 11 As shown, in some examples, each outer baffle 122 is further provided with a third guide surface 124 at both ends, and each inner baffle 121 has a mating groove formed on its outer side. The outer baffle 122 is adapted to be inserted into the mating groove. The third guide surface 124 extends gradually from top to bottom towards the mating groove. The edge of the mating groove has a mating surface that mates with the third guide surface 124. In the circumferential direction of the first frame, the third guide surface 124 and the mating surface 125 are located on both sides of the partition 13, and in the vertical direction (e.g., ... Figure 4 In the vertical direction shown, the third guide surface 124 is located above the mating surface 125, so that the third guide surface 124 on the first frame 10 can cooperate with the mating surface 125 on the second frame 20. The mating surface 125 on the first frame 10 can cooperate with the third guide surface 124 on the second frame 20, which indirectly increases the contact surface between the two frames, so that the contact surface of the two frames is evenly stressed, while avoiding sharp corner contact, which is beneficial to the cooperation between the two frames and improves the sealing performance of the wheel assembly 100.

[0066] It is understandable that each inner baffle 121 may also have a third guide surface 124 at both ends, and each outer baffle 122 may also have a mating groove formed on its inner side. The inner baffle 121 is suitable for insertion into the mating groove. The third guide surface 124 extends gradually from top to bottom towards the mating groove. The edge of the mating groove has a mating surface 125 that mates with the third guide surface 124. This can also avoid sharp corner contact and facilitate the mating of the two frames.

[0067] like Figures 1-11 As shown, in some examples, the connection structure includes a hook 51 and a slot 52, that is, the first frame 10 has both a hook 51 and a slot 52, and correspondingly, the second frame 20 also has a slot 52 and a hook 51. The hook 51 and the slot 52 can be arranged alternately along the circumference of the first frame 10, which can improve the stability of the connection between the two frames and facilitate the second frame 20 and the first frame 10 to share a mold, thus saving development costs.

[0068] Of course, hooks 51 can also be set on the outer frame 12 of the first frame 10 and slots 52 can be set on the inner frame 14. Correspondingly, hooks 51 can be set on the inner frame 14 of the second frame 20 and slots 52 can be set on the outer frame 12. The fixing effect of the two frames can be improved by the interlocking of the inner and outer sides.

[0069] like Figure 4 As shown, according to some embodiments of the present invention, the second frame 20 has the same structure as the first frame 10. The second frame 20 includes an inner frame 14, an outer frame 12, and a plurality of partitions 13. The second frame 20 can be installed above the first frame 10 (e.g., Figure 4 As shown above, the lower side of the outer frame 12 has an inner baffle 121 and an outer baffle 122. The inner baffle 121 and the outer baffle 122 are arranged alternately along the circumference of the outer frame 12. In addition, the outer side of the outer frame 12 and the inner side of the inner frame 14 both have hooks 51 and slots 52 so that the first frame 10 and the second frame 20 are fixedly connected to each other. The inner baffle 121 and the outer baffle 122 may be provided with a first guide surface 123 so that the first frame 10 and the second frame 20 can cooperate with each other.

[0070] Multiple partitions 13 are disposed between the inner frame 14 and the outer frame 12. The multiple partitions 13 are arranged at intervals along the perimeter of the second frame 20 to define multiple second spaces 21. The multiple second spaces 21 correspond to and cooperate with the first space to form an installation space for installing the adsorption component 30. The partitions 13 may be provided with second guide surfaces 131 on both sides to improve the fixing effect of the adsorption component 30 in the second frame 20.

[0071] When the first frame 10 and the second frame 20 are snapped into place, the gap between the outer wall of the adsorption component 30 and the inner outer wall of the two frames is almost zero, or even less than zero, thereby achieving an interference fit and thus achieving glue-free fixation.

[0072] In addition, the upper ends of the partition 13 and the outer frame 12 are also provided with limiting parts 16. The second air passage 22 is defined between the multiple limiting parts 16 and the inner frame. By setting the limiting parts 16, the size of the second air passage 22 is slightly smaller than the size of the adsorption member 30. Without affecting the ventilation, the adsorption member 30 can also be prevented from falling off from above.

[0073] The air handling equipment 200 according to an embodiment of the present invention includes a rotor assembly 100. By setting the rotor assembly 100, the performance of the rotor assembly 100 is guaranteed, while facilitating structural assembly and improving production efficiency.
