Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, specifically to an air supply component, an air conditioner, and an air handling equipment. Background Technology

[0002] In related technologies, the air inlets of air supply components only have the function of air intake and cannot be used for air exhaust; while the air outlets used for air exhaust can only exhaust air and cannot intake air. This single-function design restricts the direction of airflow when the number of air outlets is fixed. This not only affects the applicability of air supply components in different scenarios, but also makes it difficult to meet diverse air conditioning needs. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides an air supply component, an air conditioner, and an air handling equipment.

[0004] According to a first aspect of the present disclosure, an air supply assembly is provided, including a housing, a first motor, a first impeller, and a second impeller. The housing has a cavity and a first air outlet and a second air outlet respectively communicating with the cavity. The first motor, the first impeller, and the second impeller are all disposed in the cavity, and the first motor is disposed between the first impeller and the second impeller. The rotating shaft of the first motor can selectively drive either the first impeller or the second impeller to rotate.

[0005] In some possible implementations, the rotating shaft of the first motor is selectively connected to either the rotating shaft of the first impeller or the rotating shaft of the second impeller. When the rotating shaft of the first motor is connected to the rotating shaft of the first impeller, the blades of the first impeller can be driven to rotate when the first motor rotates, thereby drawing in external airflow through the first air inlet and blowing it out through the second air inlet. Similarly, when the rotating shaft of the first motor is connected to the rotating shaft of the second impeller, the blades of the second impeller can be driven to rotate when the first motor rotates, thereby drawing in external airflow through the second air inlet and blowing it out through the first air inlet, so that both the first and second air inlets have bidirectional functions of air intake and air exhaust.

[0006] In some possible implementations, the length of the rotating shaft is less than the distance between the rotating shafts of the first impeller and the second impeller. Because the length of the rotating shaft is less than the distance between the rotating shafts of the first and second impellers, the rotating shaft can only maintain contact with one impeller at a time, meaning it cannot be connected to both the first and second impellers simultaneously. This avoids the situation where the rotating shaft of the first motor simultaneously drives the first and second impellers to rotate.

[0007] In some possible implementations, the first motor is movably disposed between the first impeller and the second impeller, such that the rotating shaft is connected to the rotating shaft of the first impeller or to the rotating shaft of the second impeller. By driving the first motor to a position between the first and second impellers, the connection between the first motor and the rotating shaft of the first impeller or the connection between the first motor and the rotating shaft of the second impeller can be achieved.

[0008] In some possible implementations, the air supply assembly includes a guide rail on which the first motor is slidably mounted. The guide rail positions and guides the first motor, allowing it to extend along the sliding direction of the guide rail. This improves the accuracy and stability of the connection between the first motor and the first and second impellers, and also reduces frictional resistance, facilitating user adjustment.

[0009] In some possible implementations, the air supply assembly further includes a drive mechanism connected to the first motor and used to drive the first motor to move between the first impeller and the second impeller. When it is necessary to change the air supply direction, the drive mechanism can quickly move the first motor to a position connected to the corresponding impeller, realizing the switching of the connection between the first motor rotation shaft and the first impeller rotation shaft or the second impeller rotation shaft.

[0010] Compared to manually adjusting the position of the first motor, the drive mechanism makes the connection between the first motor and the impeller more stable and reliable.

[0011] In some possible implementations, the drive mechanism includes a second motor and a transmission structure. The output shaft of the second motor is connected to the first motor via the transmission structure. The output shaft of the second motor can drive the transmission structure to move, thereby causing the first motor to reciprocate between the first impeller and the second impeller. When the second motor is driven, it can drive the transmission structure to move. Thus, by rotating the second motor forward or backward, the first motor is driven to reciprocate between the first impeller and the second impeller.

[0012] In some possible implementations, the first air vent and the second air vent face different directions. Because the first air vent and the second air vent face different directions, when air enters through the first air vent and exits through the second air vent, or vice versa, the airflow can diffuse in different directions.

[0013] In some possible implementations, the first air vent is disposed on the side wall of the housing and forms a front air vent, while the second air vent is disposed on the bottom wall of the housing and forms a lower air vent. The front air vent formed on the side wall of the housing can deliver air horizontally, while the lower air vent formed on the bottom wall of the housing can deliver air vertically downward. Users can choose the air outlet direction according to their actual needs. For example, when there is a cooling need, the front air vent can be selected, and the cold air will slowly flow from top to bottom under its own gravity, covering the body from top to bottom like a shower breeze, improving the user's comfort; when there is a heating need, the lower air vent can be selected, and the hot air will slowly rise, wrapping the body from bottom to top like a carpet breeze, improving the user's comfort.

[0014] In some possible implementations, the first air inlet is connected to the air inlet of the volute of the first impeller, and the second air inlet is connected to the air inlet of the volute of the second impeller. In this way, the airflow discharged from the air inlet of the volute can flow directly out of the cavity through the first or second air inlet, resulting in a shorter flow path and improved air delivery efficiency.

[0015] In some possible implementations, at least one of the first impeller and the second impeller is a centrifugal impeller. Centrifugal impellers have higher air delivery efficiency, as well as stable operation and low vibration, resulting in better air delivery performance and improved user experience.

[0016] In some possible implementations, the bending direction of the blades of the first impeller is the same as the bending direction of the blades of the second impeller. In some possible implementations, the rotating shaft includes a first output end and a second output end. The first output end is detachably connected to a first end of the rotating shaft of the first impeller, and the second end of the rotating shaft of the first impeller is rotatably connected to the housing via a bearing. The second output end is detachably connected to the rotating shaft of the second impeller, and the second end of the rotating shaft of the second impeller is rotatably connected to the housing via a bearing. When the first output end of the first motor is connected to the rotating shaft of the first impeller, the rotation of the rotating shaft of the first motor can drive the first impeller to rotate synchronously. Similarly, when it is necessary to connect the second output shaft of the first motor to the rotating shaft of the second impeller, the first output end of the first motor can be detached from the rotating shaft of the first impeller first, and then the second output shaft of the first motor can be connected and locked to the rotating shaft of the second impeller, thereby achieving the driving of the second impeller.

[0017] In some possible implementations, a first engaging portion is formed on the first output terminal, a second engaging portion is formed on the second output terminal, a first engaging mating portion is formed on the shaft of the first impeller, and a second engaging mating portion is formed on the shaft of the second impeller. The first engaging portion engages with the first engaging mating portion, and the second engaging portion engages with the second engaging mating portion. With the engaging engagement of the first engaging portion and the first engaging mating portion, circumferential locking can be achieved, that is, circumferential locking can be achieved between the shaft of the first motor and the shaft of the first impeller, preventing relative rotation. This allows the first impeller to rotate synchronously when the shaft of the first motor rotates. Similarly, for the second impeller, with the engaging engagement of the second engaging portion and the first engaging portion, circumferential locking can be achieved, that is, circumferential locking can be achieved between the shaft of the first motor and the shaft of the second impeller, preventing relative rotation. This allows the second impeller to rotate synchronously when the shaft of the first motor rotates.

[0018] In some possible implementations, both the first and second locking portions are formed with serrated grooves. The first locking portion and the first locking mating portion are both formed with serrated grooves, and they engage when they mate. When the first locking portion and the first locking mating portion engage, the shape of the serrated grooves allows their serrations to interlock, forming a structure similar to a mechanical interlock. This effectively prevents the connecting components from loosening or falling off when subjected to external forces (such as vibration, tension, or thrust), thereby ensuring the strength and reliability of the connection.

[0019] In some possible implementations, the air supply assembly further includes a first locking connection device and a second locking connection device. The first output end is detachably connected to the shaft of the first impeller via the first locking connection device, and the second output end is detachably connected to the shaft of the second impeller via the second locking connection device. Thus, when the first impeller needs to be driven to rotate, the first locking connection device enables locking between the first output end and the shaft of the first impeller; when the second impeller needs to be driven to rotate, the second locking connection device enables locking between the second output end and the shaft of the second impeller, thereby achieving selective driving of the first and second impellers.

[0020] In some possible implementations, both the first and second locking connection devices include an electromagnetic clutch. The electromagnetic clutch includes an electromagnetic coil, an armature, and friction plates. When energized, the electromagnetic coil drives the armature to move towards or away from the friction plates. The electromagnetic coil and the armature are respectively disposed at the first and second output ends. The friction plates are respectively disposed on the shafts of the first and second impellers. The magnetic field generated by the electromagnetic coil drives the armature, thereby controlling the engagement and disengagement of the friction plates, thus realizing the transmission or interruption of power between the two rotating shafts. For example, when the electromagnetic coil is energized, it drives the armature to approach and press against the friction plates, thereby transmitting torque to the friction plates and the first or second impeller when the shaft of the first motor rotates, driving the first or second impeller to rotate.

[0021] According to a second aspect of the present disclosure, an air conditioner is provided, including the air supply assembly as described above.

[0022] In some possible implementations, the air conditioner is a ducted unit.

[0023] According to a third aspect of the present disclosure, an air handling apparatus is provided, including the air supply assembly as described above or the air conditioner as described above.

[0024] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: Since the rotating shaft of the first motor can selectively drive either the first impeller or the second impeller to rotate, when the rotating shaft of the first motor drives the first impeller to rotate, external airflow can be drawn into the cavity through the first air inlet (or the second air inlet), and the airflow can be discharged from the other of the second air inlet (or the first air inlet), thus realizing air intake through the first air inlet and air exhaust through the second air inlet. Similarly, when the rotating shaft of the first motor drives the second impeller to rotate, external airflow can be drawn into the cavity through the second air inlet (or the first air inlet), and the airflow can be discharged from the first air inlet (or the second air inlet), thus realizing air intake through the second air inlet and air exhaust through the first air inlet. This breaks the limitation of the traditional single function of air inlets, enabling both the first and second air inlets to have bidirectional functions of air intake and air exhaust.

[0025] In other words, by selectively driving different impellers, airflow can be delivered in different directions, thereby achieving more effective air circulation and regulation in different scenarios, such as room corners or specific areas. This overcomes the limitations of traditional fixed-direction air outlets and enhances the adaptability of air supply components under different spatial layouts and usage requirements.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, directional terms are used only for the convenience of describing the disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as limiting the disclosure. For example, directional terms in this scheme are defined based on the actual use state of the air supply assembly, and "inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc., are used to distinguish one element from another and do not have sequentiality or importance.

[0031] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" 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 direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0032] refer to Figures 1 to 5 As shown, according to a first aspect of the present disclosure, an air supply assembly 1 is provided, including a housing 10, a first motor 20, a first impeller 30, and a second impeller 40. The housing 10 has a cavity and a first air outlet 11 and a second air outlet 12 respectively communicating with the cavity. The first motor 20, the first impeller 30, and the second impeller 40 are all disposed in the cavity. The first motor 20 is disposed between the first impeller 30 and the second impeller 40. The rotation shaft 21 of the first motor 20 selectively drives either the first impeller 30 or the second impeller 40 to rotate.

[0033] Since the rotating shaft 21 of the first motor 20 can selectively drive either the first impeller 30 or the second impeller 40 to rotate, when the rotating shaft 21 of the first motor 20 drives the first impeller 30 to rotate, external airflow can be drawn into the cavity through the first air vent 11 (or the second air vent 12) and discharged from the other of the second air vent 12 (or the first air vent 11), thus realizing air intake through the first air vent 11 and air exhaust through the second air vent 12. Similarly, when the rotating shaft 21 of the first motor 20 drives the second impeller 40 to rotate, external airflow can be drawn into the cavity through the second air vent 12 (or the first air vent 11) and discharged from the first air vent 11 (or the second air vent 12), thus realizing air intake through the second air vent 12 and air exhaust through the first air vent 11. This breaks the limitation of the traditional single function of air vents, enabling both the first air vent 11 and the second air vent 12 to have bidirectional functions of air intake and air exhaust.

[0034] In other words, by selectively driving the first impeller 30 or the second impeller 40, airflow can be delivered in different directions, thereby achieving more effective air circulation and regulation in different scenarios, such as room corners or specific areas. This overcomes the limitations of the fixed direction of traditional air outlets and enhances the adaptability of the air supply component 1 under different spatial layouts and usage requirements.

[0035] In one embodiment provided in this disclosure, the rotating shaft 21 of the first motor 20 is selectively connected to either the rotating shaft of the first impeller 30 or the rotating shaft of the second impeller 40. Thus, when the rotating shaft 21 of the first motor 20 is connected to the rotating shaft of the first impeller 30, the blades of the first impeller 30 can be driven to rotate when the first motor 20 rotates, thereby drawing in external airflow through the first air inlet 11 and blowing it out through the second air inlet. Similarly, when the rotating shaft 21 of the first motor 20 is connected to the rotating shaft of the second impeller 40, the blades of the second impeller 40 can be driven to rotate when the first motor 20 rotates, thereby drawing in external airflow through the second air inlet 12 and blowing it out through the first air inlet 11, so that both the first air inlet 11 and the second air inlet 12 have bidirectional functions of both air intake and air exhaust.

[0036] In one exemplary embodiment provided in this disclosure, the bending direction of the blades of the first impeller 30 and the blades of the second impeller 40 may be in the same direction as the rotation direction of the rotating shaft 21 of the first motor 20.

[0037] To achieve the air intake and exhaust functions of the first air inlet 11 and the second air inlet 12, in an exemplary embodiment provided in this disclosure, the bending direction of the blades of the first impeller 30 is the same as the complete direction of the blades of the second impeller 40. For example, refer to... Figure 1 , Figure 3 As shown, the arrow points in the direction of rotation of the rotating shaft 21 of the first motor 20. When the rotating shaft 21 of the first motor 20 is connected to the rotating shaft of the first impeller 30, the rotating shaft 21 of the first motor 20, rotating counterclockwise, can drive the blades of the first impeller 30 to rotate counterclockwise as well. This allows the external airflow to enter the cavity of the first impeller 30 after being drawn in through the second air inlet 12, and then, under the pushing action of the blades of the first impeller 30, push the airflow out of the first air inlet 11. Similarly, when the rotating shaft 21 of the first motor 20 is connected to the rotating shaft of the second impeller 40, the rotating shaft 21 of the first motor 20, rotating counterclockwise, can drive the blades of the second impeller 40 to rotate counterclockwise as well. This allows the external airflow to enter the cavity of the second impeller 40 after being drawn in through the first air inlet 11, and then, under the pushing action of the blades of the second impeller 40, push the airflow out of the second air inlet 12.

[0038] To facilitate selective connection between the rotating shaft 21 of the first motor 20 and the rotating shaft of the first impeller 30 or the rotating shaft of the second impeller 40, in some possible embodiments, such as Figure 2As shown, the length of the rotating shaft 21 is less than the distance between the rotating shafts of the first impeller 30 and the second impeller 40. Because the length of the rotating shaft 21 is less than the distance between the rotating shafts of the first impeller 30 and the second impeller 40, the rotating shaft 21 can only maintain contact with one impeller at a time, meaning it cannot be connected to both the first impeller 30 and the second impeller 40 simultaneously. This avoids the situation where the rotating shaft 21 of the first motor 20 simultaneously drives the first impeller 30 and the second impeller 40 to rotate.

[0039] In this disclosure, a first motor 20 is movably disposed between a first impeller 30 and a second impeller 40, such that a rotating shaft 21 is connected to either the rotating shaft of the first impeller 30 or the rotating shaft of the second impeller 40. Thus, by driving the first motor 20 to the position between the first impeller 30 and the second impeller 40, either the connection between the first motor 20 and the rotating shaft of the first impeller 30 or the connection between the first motor 20 and the rotating shaft of the second impeller 40 can be achieved.

[0040] It should be noted that this disclosure does not limit the driving method of the first motor 20. For example, the position of the first motor 20 can be adjusted manually. For example, when airflow needs to enter from the first air outlet 11 and exit from the second air outlet 12, the first motor 20 can be manually pushed to connect with the shaft of the first impeller 30. When airflow needs to enter from the second air outlet 12 and exit from the first air outlet 11, the first motor 20 can be manually pushed to connect with the shaft of the second impeller 40.

[0041] To facilitate the movement of the first motor 20 between the first impeller 30 and the second impeller 40, in an exemplary embodiment provided in this disclosure, the air supply assembly 1 may include a guide rail, on which the first motor 20 is slidably mounted. The guide rail positions and guides the first motor 20, allowing it to extend along the sliding direction of the guide rail. This improves the accuracy and stability of the connection between the first motor 20 and the first impeller 30 and the second impeller 40, and also reduces frictional resistance, facilitating user adjustment.

[0042] In other embodiments provided in this disclosure, the first motor 20 can also be electrically driven to move between the first impeller 30 and the second impeller 40. In some possible embodiments, such as... Figure 1 , Figure 2 As shown, the air supply assembly 1 may further include a drive mechanism 50, which is connected to the first motor 20 and is used to drive the first motor 20 to move between the first impeller 30 and the second impeller 40. When it is necessary to change the air supply direction, the drive mechanism 50 can quickly move the first motor 20 to a position connected to the corresponding impeller, thereby switching the connection between the rotating shaft 21 of the first motor 20 and the rotating shaft of the first impeller 30 or the rotating shaft of the second impeller 40.

[0043] Compared to manually adjusting the position of the first motor 20, the drive mechanism 50 makes the connection between the first motor 20 and the impeller more stable and reliable.

[0044] In addition, the drive mechanism 50 can be combined with the intelligent control system to automatically drive the first motor 20 to move between the first impeller 30 and the second impeller 40 according to indoor environmental parameters (such as temperature, humidity, air quality, etc.) and user-set modes. This allows the air supply component 1 to automatically adjust the air supply direction and mode according to the actual situation without manual intervention, thus improving the intelligence level of air conditioning and providing users with a more comfortable and convenient user experience.

[0045] This disclosure does not limit the specific structure and driving method of the aforementioned drive mechanism 50. In the first exemplary embodiment provided in this disclosure, such as... Figure 1 , Figure 2 As shown, the drive mechanism 50 may include a second motor 51 and a transmission structure 500. The output shaft of the second motor 51 is connected to the first motor 20 through the transmission structure 500. The output shaft of the second motor 51 can drive the transmission structure 500 to move, thereby causing the first motor 20 to reciprocate between the first impeller 30 and the second impeller 40. In this way, when the second motor 51 is driven, it can drive the transmission structure 500 to move. Thus, by rotating the second motor 51 forward or backward, the first motor 20 is driven to reciprocate between the first impeller 30 and the second impeller 40.

[0046] Here, it is necessary to add that, such as Figure 1 , Figure 2 As shown, the transmission structure 500 described above may include a lead screw and nut pair, that is, the lead screw and nut pair includes a lead screw 52 and a nut 53. The output shaft of the second motor 51 is connected to the lead screw 52, ​​the nut 53 is threaded onto the lead screw 52, ​​and the first motor 20 is connected to the nut 53. In this way, when the output shaft of the second motor 51 rotates, it can drive the lead screw 52 to rotate, which in turn drives the nut 53 connected to the lead screw 52 to rotate. During the rotation, the nut 53 can achieve radial displacement of the lead screw 52, ​​thereby driving the first motor 20 connected to the nut 53 to move, and realizing the adjustment of the position of the first motor 20.

[0047] In other embodiments provided in this disclosure, the drive mechanism 50 may also include a cylinder, the telescopic rod of which is connected to the first motor 20. In this way, during the extension and retraction of the telescopic rod of the cylinder, the first motor 20 can also be driven to reciprocate between the first impeller 30 and the second impeller 40.

[0048] In order to increase the air supply range of the aforementioned air supply component 1, such as Figure 1 , Figure 3As shown, in some possible implementations, the first air vent 11 and the second air vent 12 face different directions. Since the first air vent 11 and the second air vent 12 face different directions, when air enters through the first air vent 11 and exits through the second air vent 12, or when air enters through the second air vent 12 and exits through the first air vent 11, the airflow can diffuse in different directions.

[0049] For example, the first vent 11 directs airflow to the left front, and the second vent 12 directs airflow to the right front, thus expanding the coverage angle and area of ​​the airflow in the horizontal plane. The same principle applies in the vertical direction. If the two vents have different orientations in the vertical direction, the vertical airflow range can also be increased, allowing more areas in the entire space to be supplied with airflow, effectively avoiding the dead zones that exist in traditional single-direction airflow.

[0050] In one exemplary embodiment provided in this disclosure, a first air vent 11 is disposed on the side wall of the housing 10 and forms a front air vent, and a second air vent 12 is disposed on the bottom wall of the housing 10 and forms a lower air vent. The front air vent formed on the side wall of the housing 10 can deliver air horizontally, while the lower air vent formed on the bottom wall of the housing 10 can deliver air vertically downward. Users can select the air outlet direction according to their actual needs. For example, when there is a cooling need, the front air vent can be selected, and the cold air will slowly flow from top to bottom under its own gravity, covering the human body from top to bottom like a shower breeze, improving the user's comfort; when there is a heating need, the lower air vent can be selected, and the hot air will slowly rise, wrapping the human body from bottom to top like a carpet breeze, improving the user's comfort.

[0051] In some possible implementations, such as Figure 1 , Figure 3 As shown, the first air inlet 11 is connected to the air inlet of the volute of the first impeller 30, and the second air inlet 12 is connected to the air inlet of the volute of the second impeller 40. In this way, the airflow discharged from the air inlet of the volute can flow directly out of the cavity through the first air inlet 11 or the second air inlet 12, with a shorter flow path and improved air delivery efficiency.

[0052] This disclosure does not limit the specific types of the first impeller 30 and the second impeller 40 mentioned above. For example, in an exemplary embodiment provided in this disclosure, at least one of the first impeller 30 and the second impeller 40 can be a centrifugal impeller. Centrifugal impellers have high air delivery efficiency, stable operation, and low vibration characteristics, resulting in better air delivery performance and improved user experience.

[0053] In other embodiments provided in this disclosure, the first impeller 30 and the second impeller 40 may also be axial flow impellers or cross flow impellers, etc., and this disclosure does not limit them.

[0054] Furthermore, this disclosure does not limit the connection structure and connection method between the rotating shaft 21 of the first motor 20 and the first impeller 30, or between the rotating shaft 21 of the first motor 20 and the second impeller 40. For example, the rotating shaft 21 may include a first output end 210 and a second output end 220. The first output end 210 is used to be detachably connected to the first end of the rotating shaft of the first impeller 30, and the second end of the rotating shaft of the first impeller 30 is rotatably connected to the housing 10 through a bearing 110. The second output end 220 is used to be detachably connected to the rotating shaft of the second impeller 40, and the second end of the rotating shaft of the second impeller 40 is rotatably connected to the housing 10 through a bearing 110. In this way, when the first output end 210 of the first motor 20 is connected to the rotating shaft of the first impeller 30, the rotation of the rotating shaft 21 of the first motor 20 can drive the first impeller 30 to rotate synchronously. Similarly, when it is necessary to connect the second output shaft of the first motor 20 to the rotating shaft of the second impeller 40, the first output end 210 of the first motor 20 can be unlocked from the rotating shaft of the first impeller 30 first, and then the second output shaft of the first motor 20 can be connected and locked to the rotating shaft of the second impeller 40, thereby realizing the driving of the second impeller 40.

[0055] In some possible implementations, a first snap-fit ​​portion 211 is formed on the first output terminal 210, a second snap-fit ​​portion 221 is formed on the second output terminal 220, a first snap-fit ​​mating portion 31 is formed on the shaft of the first impeller 30, and a second snap-fit ​​mating portion 41 is formed on the shaft of the second impeller 40. The first snap-fit ​​portion 211 and the first snap-fit ​​mating portion 31 are snapped together, and the second snap-fit ​​portion 221 and the second snap-fit ​​mating portion 41 are snapped together. With the engaging engagement of the first engaging part 211 and the first engaging mating part 31, circumferential locking can be achieved, that is, circumferential locking can be achieved between the rotating shaft 21 of the first motor 20 and the rotating shaft of the first impeller 30, and the two cannot rotate relative to each other. Thus, when the rotating shaft 21 of the first motor 20 rotates, it drives the first impeller 30 to rotate synchronously. Similarly, with the second impeller 40, with the engaging engagement of the second engaging part 221 and the first engaging mating part 31, circumferential locking can be achieved, that is, circumferential locking can be achieved between the rotating shaft 21 of the first motor 20 and the rotating shaft of the second impeller 40, and the two cannot rotate relative to each other. Thus, when the rotating shaft 21 of the first motor 20 rotates, it drives the second impeller 40 to rotate synchronously.

[0056] In the first exemplary embodiment provided in this disclosure, such as Figure 1 , Figure 2As shown, both the first engaging portion 211 and the second engaging portion 221 are formed with serrated grooves, as are the first engaging mating portion 31 and the second engaging mating portion 41. The first engaging portion 211 and the first engaging mating portion 31 mesh when they are joined, and the first engaging mating portion 31 and the second engaging mating portion 41 mesh when they are joined. When the first engaging portion 211 and the first engaging mating portion 31 mesh, the shape of the serrated grooves allows their serrations to interlock, forming a structure similar to a mechanical interlock. This effectively prevents the connecting parts from loosening or falling off when subjected to external forces (such as vibration, tension, or thrust), thereby ensuring the firmness and reliability of the connection.

[0057] Alternatively, in other embodiments provided in this disclosure, the first engaging part 211, the second engaging part 221, the first engaging mating part 31, and the second engaging mating part can all be geared discs. When the geared disc provided on the rotating shaft 21 moves to a specific position in the direction of the first impeller 30, the geared disc can mesh with the geared disc provided on the rotating shaft of the first impeller 30, thereby realizing the transmission between the rotating shaft 21 and the first impeller 30. Similarly, when the geared disc provided on the rotating shaft 21 moves to a specific position in the direction of the first impeller 30, the geared disc can mesh with the geared disc provided on the rotating shaft of the second impeller 40, thereby realizing the transmission between the rotating shaft 21 and the second impeller 40.

[0058] In the second embodiment provided in this disclosure, the air supply assembly 1 may further include a first locking connection device 60 and a second locking connection device 61. The first output end 210 is detachably connected to the shaft of the first impeller 30 via the first locking connection device 60, and the second output end 220 is detachably connected to the shaft of the second impeller 40 via the second locking connection device 61. Thus, when the first impeller 30 needs to be driven to rotate, the first locking connection device 60 can lock the first output end 210 to the shaft of the first impeller 30; when the second impeller 40 needs to be driven to rotate, the second locking connection device 61 can lock the second output end 220 to the shaft of the second impeller 40, thereby achieving selective driving of the first impeller 30 and the second impeller 40.

[0059] In the second exemplary embodiment provided in this disclosure, such as Figure 3 , Figure 4As shown, both the first locking connection device 60 and the second locking connection device 61 may include an electromagnetic clutch 600. The electromagnetic clutch 600 includes an electromagnetic coil, an armature, and friction plates. When energized, the electromagnetic coil can drive the armature to move towards or away from the friction plates. The first output end 210 and the second output end 220 are respectively provided with an electromagnetic coil and an armature. The shafts of the first impeller 30 and the second impeller 40 are respectively provided with friction plates. The magnetic field generated by the electromagnetic coil drives the armature, thereby controlling the engagement and disengagement of the friction plates, thus realizing the transmission or interruption of power between the two rotating shafts. For example, when the electromagnetic coil is energized, it drives the armature to approach and press against the friction plates, thereby transmitting torque to the friction plates and the first impeller 30 or the second impeller 40 when the rotating shaft 21 of the first motor 20 rotates, driving the first impeller 30 or the second impeller 40 to rotate.

[0060] Since the first output terminal 210 and the second output terminal 220 are respectively connected to their respective impeller shafts via independent electromagnetic clutches 600, the operating states of the two impellers can be controlled independently. For example, depending on actual needs, only one impeller can be driven, or both impellers can be driven simultaneously, or even the two impellers can operate at different speeds. This independent control capability provides great flexibility for optimizing air supply effects. For example, if the two impellers are responsible for air supply in different directions, the air supply intensity in each direction can be precisely controlled through the electromagnetic clutches 600; or, in some cases, a lower air supply volume may be required, in which case only one impeller can be driven or the speed of both impellers can be reduced to achieve energy saving; or, if one impeller or its drive system fails, the other impeller can still operate independently to ensure basic air supply function and improve system reliability.

[0061] In other embodiments provided in this disclosure, the first locking connection device 60 and the second locking connection device 61 may both include a hydraulic clutch or a pneumatic clutch, and this disclosure does not limit this.

[0062] In the third embodiment provided in this disclosure, such as Figure 5 As shown, there can be two first motors 20 mentioned above. One first motor 20 is used to drive the first impeller 30 to rotate, while the other first motor 20 is used to drive the second impeller 40 to rotate. In this way, the user can start the first motor 20 connected to the first impeller 30 or the first motor 20 connected to the second impeller 40 according to actual needs, so that the airflow can enter from the first air outlet 11 and exit from the second air outlet 12 or vice versa.

[0063] In addition, such as Figures 1 to 4As shown, the housing 10 in this disclosure may further include a partition 70, and the air supply assembly 1 may further include a thermoelectric auxiliary 80, an evaporator 90, and a water collection tray 100. The partition 70 can divide the space inside the housing 10 into the aforementioned cavity and a temperature regulating cavity. The first air outlet 11 or the second air outlet 12 is connected to the temperature regulating cavity. The thermoelectric auxiliary 80 and the evaporator 90 are disposed in the temperature regulating cavity and can heat or cool the temperature flowing through the temperature regulating cavity. The water collection tray 100 is disposed at the bottom of the temperature regulating cavity for collecting condensate.

[0064] According to a second aspect of the present disclosure, an air conditioner is provided, including the air supply assembly 1 as described above. This air conditioner has all the beneficial effects of the air supply assembly 1 described above, which will not be elaborated upon here.

[0065] This disclosure does not limit the specific type of air conditioner described above. For example, in one exemplary embodiment provided in this disclosure, the air conditioner is a ducted air conditioner.

[0066] Alternatively, in other embodiments provided in this disclosure, the air conditioner may also be a central air conditioner, a split air conditioner (such as a wall-mounted, floor-standing, or cabinet type), or a portable air conditioner.

[0067] According to a third aspect of the present disclosure, an air handling apparatus is provided, including the air supply assembly 1 as described above or the air conditioner as described above. This air handling apparatus has all the beneficial effects of the air supply assembly 1 and the air conditioner described above, which will not be described further herein.

However, this disclosure is not limited to the specific details of the above embodiments.

In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0070] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
