[0011] In some examples, the center cap includes a first body adapted to be inserted into and fixedly connected to the inner ring, and the first clamping structure forms a clamping protrusion protruding outward from the outer side of the first body.

[0012] In some examples, it also includes: an outer peripheral cap, which is fixedly connected to the outer ring, and the outer peripheral cap has a second clamping structure for clamping the adsorption element.

[0013] In some examples, the outer peripheral cap includes a second body adapted to be inserted into and fixedly connected to the outer ring, and the second clamping structure forms a clamping protrusion protruding from the inner side of the second body.

[0014] In some examples, the inner ring has an outwardly extending flange on the side opposite to the rotary cover, and / or the outer ring has an inwardly extending flange on the side opposite to the rotary cover, the flange being adapted to stop the adsorption element.

[0015] In some examples, the outer surface of the inner ring has an outwardly protruding limiting rib, and / or the inner surface of the outer ring has an inwardly protruding limiting rib, the limiting rib being adapted to abut against the adsorption member.

[0016] In some examples, a partition strip is also included, the connector comprising two connecting ribs having a mating gap between the two connecting ribs, a portion of the partition strip extending into the mating gap to close the mating gap, and a rotary cap adapted to press the end of the partition strip.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[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 1-8 A rotary wheel assembly 100 according to an embodiment of the present invention is described.

[0040] like Figures 1-8 As shown, a rotating wheel assembly 100 according to an embodiment of the present invention includes: a rotating wheel frame 10, a rotating wheel cover 20, and an adsorption member 30. The adsorption member 30 can be disposed inside the rotating wheel frame 10. The rotating wheel cover 20 cooperates with the rotating wheel frame 10, thereby fixing the adsorption member 30 to the rotating wheel frame 10. That is, the rotating wheel frame 10 is an integral part, and the adsorption member 30 is directly installed inside the rotating wheel frame 10. Effective fixing is achieved through the rotating wheel cover 20, ensuring the stability and reliability of the overall structure.

[0041] According to the embodiment of the present invention, the rotating wheel assembly 100 defines a receiving space 101 for mounting the adsorption component 30 by the rotating wheel frame 10. The adsorption component 30 is fixed by the cooperation between the rotating wheel cover 20 and the rotating wheel frame 10. The overall components are few and easy to assemble. Moreover, the rotating wheel frame 10 is an integral part and does not require its own assembly, which avoids the risk of cracking of the rotating wheel frame 10. The structure has good stability, which can improve the coaxiality of the various structures when the rotating wheel assembly 100 rotates, ensure the stability and reliability of rotation, avoid large radial and axial runout of the rotating wheel assembly 100 during operation, and avoid scraping against other external parts, which facilitates the widespread application of the rotating wheel assembly 100.

[0042] The rotating frame 10 defines a receiving space 101, which can be connected to the outside. The adsorption element 30 can be placed in the receiving space 101. The adsorption element 30 can be a zeolite molecular sieve. Utilizing the material properties of zeolite, the adsorption element 30 can absorb water vapor in the air at room temperature and release the absorbed water vapor at high temperature. Thus, the function of regulating indoor air humidity can be achieved without using high-power equipment such as compressors. Of course, the adsorption element 30 can also be other adsorbent materials, such as silica gel or MOF.

[0043] like Figure 6 As shown, according to some embodiments of the present invention, the wheel frame 10 includes an inner ring 11, an outer ring 12, and a plurality of connecting members 13. The outer ring 12 is disposed outside the inner ring 11, and the connecting members 13 are disposed between the inner ring 11 and the outer ring 12. The inner end of the connecting member 13 is connected to the inner ring 11, and the outer end is connected to the outer ring 12. Thus, the wheel frame 10 forms an integrated structure, that is, the wheel frame 10 is designed in the form of inner and outer rings. The inner and outer rings 12 are connected by the connecting members 13. The inner and outer rings can be arranged concentrically, which can reduce the axial runout and radial runout problems caused by the misalignment of the inner and outer rings during manufacturing, and can also increase the smoothness and reliability of the operation of the wheel assembly 100.

[0044] In some examples, the inner ring 11 and the outer ring 12 each form an annulus, which can be a square annulus or a circular annulus. The outer ring 12 is concentric with the inner ring 11 and arranged at intervals. The connector 13 can separate multiple receiving spaces 101 between the inner ring 11 and the outer ring 12. Each receiving space 101 can be equipped with an adsorption element 30, the shape of which corresponds to the receiving space 101. The adsorption element 30 can be directly placed in the receiving space 101. The rotating cover 20 cooperates with the inner ring 11, or with the outer ring 12, or with both the inner ring 11 and the outer ring 12, to achieve overall fixation. It can also be fixed by a small amount of glue. Compared with the separate inner and outer frame in the prior art, this reduces the glue application points, improves processability, and reduces the risk of cracking of the rotating frame 10.

[0045] According to some embodiments of the present invention, the rotating frame 10 is a plastic part, and the inner and outer rings can be integrally injection molded. The adsorption component 30 is driven to move by the plastic part, avoiding the adsorption component 30 being directly driven by the driving component, which can reduce the risk of cracking of the adsorption component 30 during long-term operation and improve reliability. In addition, the plastic part is lightweight, low in cost, simple in process, and easy to manufacture.

[0046] In some examples, the connectors 13 may include multiple connectors arranged at equal intervals. For example, there may be three connectors 13, which divide the wheel frame 10 into three identical receiving spaces 101. Alternatively, there may be two connectors 13, which divide the wheel frame into two identical receiving spaces 101. Of course, multiple connectors 13 may also be arranged non-uniformly, and the resulting receiving spaces 101 may have a non-uniform structure. This can be flexibly adjusted according to the actual application scenario and is not limited here.

[0047] According to some embodiments of the present invention, the rotary pressure cap 20 includes a central pressure cap 21, which is fixedly fitted with an inner ring 11. The central pressure cap 21 has a first pressing structure 214 extending onto the receiving space 101. The first pressing structure 214 can press a portion of the adsorption member 30, thereby limiting the position of the adsorption member 30. The fixing method here can be a snap-fit, which connects the central pressure cap 21 and the inner ring 11, improving assembly efficiency. Of course, other connection methods such as screw connection can also be used.

[0048] like Figure 5 and Figure 7 As shown, in some examples, the center cap 21 has an annular groove 211 extending circumferentially, and the inner ring 11 has a plurality of spaced hooks 113. When the center cap 21 is fastened onto the rotating frame 10, the annular groove 211 can engage with the hooks 113, thereby fixing the center cap 21.

[0049] The center cap 21 also has a limiting block 212, and the inner ring 11 also has a limiting groove 114. The limiting groove 114 extends along the axial direction of the inner ring 11. The center cap 21 can be fastened to the inner ring 11 along the axial direction of the inner ring 11. By interlocking the limiting block 212 with the limiting groove 114, the center cap 21 can be prevented from rotating relative to the wheel frame 10, thus limiting the degree of freedom in this direction and ensuring a reliable fit between the center cap 21 and the inner ring 11.

[0050] Of course, the limiting groove 114 can also be set on the center pressure cover 21, and the limiting block 212 can be set on the inner ring 11. With the insertion and cooperation of the limiting block 212 and the limiting groove 114, the installation of the center pressure cover 21 can be guided, and the stability of the overall structure can be improved.

[0051] like Figure 5 As shown, in some examples, the central pressure cap 21 includes a first body 213, which can be inserted into the inner ring and is fixedly connected to the inner ring. The first pressing structure 214 forms a pressing protrusion protruding from the outside of the first body 213. It can be a ring structure or a multi-segment protrusion structure arranged at intervals, so as to achieve pressing of the adsorption component.

[0052] like Figure 4 As shown, in some examples, the rotary cover 20 further includes an outer peripheral cover 22, which is fixedly connected to the outer ring 12. The outer peripheral cover 22 has a second pressing structure 224 that can extend to the receiving space 101. The second pressing structure 224 can press a part of the adsorption member 30 to limit the adsorption member 30.

[0053] The outer peripheral cover 22 has a snap-fit ​​221 on its outer peripheral surface, and the inner peripheral surface of the outer ring 12 has a snap-fit ​​123. The outer peripheral cover 22 can extend into the inner side of the outer ring 12. Through the cooperation of the snap-fit ​​221 and the snap-fit ​​123, the outer peripheral cover 22 and the outer ring 12 are locked together, which is convenient and reliable. Of course, the snap-fit ​​221 can also be provided on the inner peripheral surface of the outer peripheral cover 22, or it can be provided on the outer ring 12.

[0054] like Figure 4 As shown, the outer peripheral pressure cover 22 includes a second body 223, which can be inserted into the outer ring. The second body 223 is fixedly connected to the outer ring. The second pressing structure 224 forms a pressing protrusion protruding from the inner side of the second body 223. It can be a ring structure or a multi-segment protrusion structure arranged at intervals, so as to achieve pressing of the adsorption component.

[0055] like Figure 4 and 6As shown, in some examples, the rotary cover 20 can be installed on the upper side of the rotary frame 10, and the lower side of the inner ring 11 has an outwardly extending first flange 111. When the adsorption member 30 is installed into the receiving space 101, the first flange 111 stops the adsorption member 30, thereby limiting the adsorption member 30 and preventing the adsorption member 30 from coming out from the lower side of the rotary frame 10.

[0056] like Figure 6 As shown, in some examples, the lower side of the outer ring 12 has an inwardly extending second flange 121. When the adsorbent 30 is installed into the receiving space 101, the second flange 121 stops the adsorbent 30, thereby limiting the adsorbent 30 and preventing the adsorbent 30 from coming off the lower side of the rotating frame 10.

[0057] like Figure 6 As shown, in some examples, the outer side of the inner ring 11 has an outwardly protruding first limiting rib 112. When the adsorption member 30 is installed into the receiving space 101, the first limiting rib 112 can abut against the adsorption member 30 and can be interference-fitted to clamp the adsorption member 30 into the receiving space 101, avoiding shaking caused by the adsorption member 30 not fully fitting against the wall of the receiving space 101, thus reducing the manufacturing precision of the adsorption member 30.

[0058] like Figure 6 As shown, in some examples, the inner side of the outer ring 12 has an inwardly protruding second limiting rib 122. When the adsorption member 30 is installed into the receiving space 101, the second limiting rib 122 can abut against the adsorption member 30 and can be interference-fitted to clamp the adsorption member 30 in the receiving space 101, avoiding shaking caused by the adsorption member 30 not being completely attached to the wall of the receiving space 101, which would reduce the manufacturing precision of the adsorption member 30.

[0059] The limiting rib can have an inclined outer surface, which facilitates mold ejection and guides the adsorption component 30 during installation.

[0060] It is understandable that a first flange 111 and a first limiting rib 112 can be provided on the inner ring 11 at the same time, and a second flange 121 and a second limiting rib 122 can also be provided on the outer ring 12 at the same time. The flange and the limiting rib can play a preliminary role in fixing the installation of the adsorption component 30.

[0061] like Figure 6 As shown, in some examples, in order to improve the structural strength of the connector 13 and thus improve the stability of the overall structure, the connector 13 may include two interconnected connecting ribs 131 with a fitting gap between the two connecting ribs 131. This eliminates the need to make the connector 13 larger, making it easier to demold, saving materials and reducing weight.

[0062] like Figures 2-4 As shown, in some examples, after the adsorption element 30 is installed into the receiving space 101, a partition strip 14 is provided between two adjacent adsorption elements 30. A portion of the partition strip 14 extends into the mating gap. The partition strip 14 abuts or presses against the connecting rib 131, sealing the mating gap. The rotating cover 20 can press down on the end of the partition strip 14. For example, the center cover 21 can press down on one end of the partition strip 14, and the outer peripheral cover 22 can press down on the other end of the partition strip 14, thus fixing the partition strip 14. After the partition strip 14 is pressed in and fixed, sealant can be applied to the upper and lower grooves of the connector 13, i.e. Figure 2 and Figure 3 The glue application area 141 shown in the figure achieves complete fixation of the rotary wheel assembly.

[0063] In addition, the center pressure cap 21 and the outer peripheral pressure cap 22 can also be directly connected to the partition pressure strip 14 to form a whole, thereby reducing structural parts, facilitating assembly, and improving structural stability.

[0064] like Figure 1 As shown, in some examples, the inner side of the inner ring 11 also has a connecting plate 115, and the connecting plate 115 has a connecting hole 102 in the middle. The connecting hole 102 is an irregular hole, and the connecting hole 102 can be connected to the driving component so that the driving component can drive the entire wheel assembly 100 to rotate, thereby realizing direct drive.

[0065] In addition, the connecting plate 115 has clearance holes, which facilitate the demolding of structures such as the hooks 113 on the inner ring 11, and facilitate the integral manufacturing of the wheel frame 10.

[0066] like Figure 8 As shown, in some examples, the outer ring 12 has a toothed ring 124 on its outer side, which can mesh with a gear located on the outer side of the wheel assembly 100. The drive member drives the toothed ring 124 to rotate by rotating the drive gear, so that the drive member can drive the entire wheel assembly 100 to rotate, thereby realizing gear drive.

[0067] Of course, a belt groove can also be provided on the outer side of the outer ring 12. The belt groove can be used to install a belt. The drive unit drives the belt to rotate, which in turn drives the entire pulley assembly 100 to rotate, thus realizing belt drive.

[0068] like Figure 9As shown, the air handling equipment 1000 according to an embodiment of the present invention includes a rotor assembly 100 according to an embodiment of the present invention. By adopting the rotor assembly 100, the coaxiality of each structure of the rotor assembly 100 is improved when it rotates, ensuring the stability and reliability of rotation, avoiding large radial and axial runout of the rotor assembly 100 during operation, avoiding scraping against other parts of the air handling equipment 1000, etc., thereby improving the service life of the whole machine, reducing maintenance, and improving the user experience.

[0069] According to some embodiments of the present invention, the air handling equipment 1000 has a first air duct and a second air duct. The first air duct is used to supply air from the outside to the inside, and the second air duct is used to exhaust air from the inside to the outside, thereby realizing air circulation. The rotary wheel assembly 100 is installed inside the air handling equipment 1000, and half of the adsorbent 30 is arranged in the first air duct and half in the second air duct. The adsorbent 30 can automatically adsorb water vapor passing through it at room temperature, and when the air passing through it is a high-temperature airflow, the adsorbent 30 can automatically release the previously adsorbed water vapor.

[0070] Specifically, when the air discharged from the second air duct is room temperature indoor air, as the air passes through the adsorbent 30, the adsorbent 30 adsorbs water vapor from the air. The rotor assembly rotates inside the device. When the rotor portion adsorbing water vapor rotates to the first air duct, the front end of the supply air duct is equipped with a purification component and a heating component, which can increase the supply air temperature. When the high-temperature airflow passes through the adsorbent 30, it can carry away the water vapor adsorbed inside the molecular sieve rotor, thus delivering high-temperature, high-humidity clean air to the room, thereby achieving waterless humidification. In addition, the adsorbent 30 also has good heat exchange capabilities. When the air discharged from the second air duct is high-temperature indoor air, the rotor assembly can absorb high-temperature heat, achieving total heat recovery. Therefore, the air handling equipment 1000 can achieve both waterless humidification and total heat recovery functions.

[0071] In some examples, during winter, the rotor assembly 100 rotates slowly (e.g., 0.5 rpm) to achieve waterless humidification, which can humidify the dry indoor environment during winter; during summer, the rotor assembly 100 can rotate quickly (e.g., 15 rpm) to achieve total heat recovery.

[0072] Other configurations and operations of the air handling device 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0073] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0074] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.
