Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

The embodiment of the utility model provides a wind wheel assembly, which solves the problem that two wind wheels on the existing double-shaft motor can only be opened or closed simultaneously, and is described below with reference to the accompanying drawings.

In an embodiment of the present utility model, as shown in fig. 1 to 3, the wind wheel assembly 100 includes a mounting case 10, a double shaft motor 20, a first wind wheel 30, a second wind wheel 40, and a pulling assembly 50. Wherein, a mounting cavity 13 is disposed in the mounting shell 10, specifically, in this embodiment, the mounting shell 10 includes an upper volute 11 and a lower volute 12 that are connected to each other, the mounting cavity 13 in the mounting shell 10 is also divided into a first mounting cavity 131 and a second mounting cavity 132, and the first mounting cavity 131 is located below the second mounting cavity 132. In actual use, one of the first installation chamber 131 and the second installation chamber 132 may be configured as a fresh air chamber, and the other may be configured as an exhaust chamber. For example, in the present embodiment, the first installation cavity 131 is a fresh air cavity, and the second installation cavity 132 is an exhaust cavity.

The dual-shaft motor 20 is disposed in the mounting cavity 13, and the dual-shaft motor 20 is provided with a first output shaft 21 extending downward and a second output shaft 22 extending upward, that is, the first output shaft 21 extends downward and into the first mounting cavity 131, and the second output shaft 22 extends upward and into the second mounting cavity 132. Here, the first output shaft 21 extends downward in the direction of gravity, and the second output shaft 22 extends upward in the direction opposite to the direction of gravity.

The first wind wheel 30 is disposed in the first mounting cavity 131 and connected to the first output shaft 21, and the first output shaft 21 may drive the first wind wheel 30 to rotate.

The second wind wheel 40 is disposed in the second mounting cavity 132 and connected to the second output shaft 22, the second output shaft 22 may drive the second wind wheel 40 to rotate, and the second wind wheel 40 may move upward along the axial direction of the second output shaft 22 and be disconnected from the second output shaft 22. Specifically, in the present utility model, when the second wind wheel 40 is mounted on the second output shaft 22, the second output shaft 22 restricts the circumferential movement of the second wind wheel 40, but does not restrict the upward movement of the second wind wheel 40. Accordingly, the connection structure between the second wind wheel 40 and the second output shaft 22 may have various manners, for example, as can be understood with reference to fig. 6 and 7, the second wind wheel 40 may be provided with a connection hole 42 with a hole bottom facing downward, and an end portion of the second output shaft 22 is clamped into the connection hole 42 and abuts against the hole bottom of the connection hole 42, so as to support the second wind wheel 40, and the second wind wheel 40 keeps connected to the second output shaft 22 by means of self gravity without external force. Or, the connecting hole 42 on the second wind wheel 40 is a through hole, the outer circumferential surface on the second output shaft 22 is provided with a supporting step 223, the outer diameter of the supporting step 223 is larger than the inner diameter of the connecting hole 42 of the second wind wheel 40, and at this time, the second output shaft 22 can support the second wind wheel 40 through the supporting step 223 without limiting the upward movement of the second wind wheel 40. Still alternatively, the second output shaft 22 may be sleeved with a bearing sleeve, and the second wind wheel 40 may be supported by the bearing sleeve, where the second output shaft 22 only needs to limit the circumferential movement of the second wind wheel 40.

However, for the implementation manner of limiting the circumferential movement of the second wind wheel 40 by the second output shaft 22, various options are also available, such as the cross sections of the second output shaft 22 and the connecting hole 42 on the second wind wheel 40 are set to be non-circular, so that the second output shaft 22 drives the second wind wheel 40 to rotate, and the second wind wheel 40 is not limited to move upwards. For another example, the outer circumference of the second output shaft 22 and the inner circumference of the connection hole 42 are respectively provided with connection teeth, and racks of the connection teeth extend in the axial direction of the second output shaft 22. For another example, the outer peripheral surface of the second output shaft 22 is convexly provided with a flat key, the flat key extends along the axial direction of the second output shaft 22, the inner wall of the connecting hole 42 is correspondingly provided with a key groove, the key groove penetrates to the orifice along the axial direction of the second output shaft 22, and the flat key is clamped in the key groove during assembly.

In summary, the specific connection structure between the second wind wheel 40 and the second output shaft 22 can be flexibly selected according to the needs, so long as the second output shaft 22 is ensured to be capable of driving the second wind wheel 40 to rotate, and the second wind wheel 40 is capable of moving upwards and separating from the second output shaft 22.

Further, as shown in fig. 5 and 6, a pull tab 41 is further disposed on the second wind wheel 40, the pull tab 41 is located on the rotation axis of the second wind wheel 40, and the pull tab 41 is provided with a lifting portion 411. Specifically, in this embodiment, a connecting seat is provided at the center of the second wind wheel 40, a connecting hole 42 for connecting with the second output shaft 22 is provided on the connecting seat, a pull lug 41 is provided at the top of the connecting seat, and the pull lug 41 is provided with a lifting part 411, where the lifting part 411 is used to provide a stress point for the lifting member 51 (refer to fig. 4), so as to receive an upward acting force when the lifted member 51 abuts, and further drive the pull lug 41 and the second wind wheel 40 to move upward. Thus, the pulling portion 411 may be rod-shaped, plate-shaped, block-shaped, disk-shaped, or the like, as long as the pulling portion 411 has a downward force-receiving surface; in addition, since the lifting portion 411 rotates with the second wind wheel 40, the specific structure of the lifting portion 411 needs to be designed with the lifting member 51 to ensure that the lifting portion 411 can be always located above at least a portion of the lifting member 51 no matter where the lifting portion rotates with the second wind wheel 40 or the extending angle. For example, in the present embodiment, the outer shape of the lifting portion 411 is a circular plate, so that the lifting portion 411 can be guaranteed to be abutted by the lifting member 51 moving upwards no matter what rotation is performed, in this case, the outer shape of the lifting member 51 may be a circular ring, a long strip, a square plate, a hook or the like.

Referring to fig. 1, 2 and 4, the second wind wheel 40 is lifted by the lifting assembly 50 according to the present utility model, so that the wind wheel moves upwards and is separated from the connection with the second output shaft 22, specifically, as shown in fig. 4, the lifting assembly 50 includes a lifting member 51 and a driving member 52, the lifting member 51 is at least partially suspended below the lifting portion 411, the driving member 52 is mounted on the mounting case 10, and the driving member 52 is used for driving the lifting member 51 to move upwards and downwards along the axial direction of the second output shaft 22, where, as described above, the specific shape of the lifting member 51 may be designed according to the shape of the lifting portion 411 of the lifting lug 41. For example, when the pulling portion 411 of the pulling lug 41 is in a circular plate shape, the pulling member 51 may be in a hook shape, and the hook portion extends to the lower portion of the pulling portion 411 and is suspended.

For example, in an embodiment, referring to fig. 4 to 6, the pull tab 41 further includes a connecting portion 412, and the connecting portion 412 extends along the axial direction of the second output shaft 22, that is, the connecting portion 412 has a substantially cylindrical shape, and may specifically be a cylinder, an elliptic cylinder, a polygonal cylinder (e.g., a triangular prism, a quadrangular prism, a hexagonal prism), or the like. The lifting portion 411 is disposed on the connecting portion 412, and the lifting portion 411 at least partially protrudes with respect to the outer peripheral surface of the connecting portion 412, specifically, the lifting portion 411 may be integrally formed with the connecting portion 412, or may be mounted on the connecting portion 412 by screwing, fastening, bonding, or the like, and the lifting portion 411 may be disposed at the top end of the connecting portion 412 or may be disposed in the middle of the connecting portion 412, so long as the lifting portion 411 at least partially protrudes out of the outer peripheral surface of the connecting portion 412. The pulling member 51 is a pull ring surrounding the connecting portion 412, and the pull ring may be a circular ring, an elliptical ring, a square ring, a triangular ring, or the like, so long as the external design of the connecting portion 412 is adapted. In addition, in the radial direction of the connection portion 412, the distance between the inner circumferential wall of the tab and the outer circumferential surface of the connection portion 412 is smaller than the protruding length of the pulling portion 411 with respect to the outer circumferential surface of the connection portion 412, that is, the pulling portion 411 may restrict the pulling member 51 from being separated upward from the connection portion 412, and when the pulling member 51 moves upward, it is inevitably abutted to the pulling portion 411, thereby lifting the pulling portion 411 upward.

When the drawer 51 is a tab, the drawer 411 is always located directly above a certain portion of the drawer 51, regardless of how the drawer 411 rotates. Therefore, when the pulling member 51 is a tab, the pulling portion 411 may be designed in any shape as long as it protrudes with respect to the outer peripheral surface of the connecting portion 412 and is located directly above the pulling member 51. For example, the pulling portion 411 may be in a rod shape, a block shape, or the like extending from the outer peripheral surface of the connecting portion 412; for another example, as shown in fig. 5 and 6, the pulling part 411 is a circular plate coaxially disposed with the connecting part 412, the pulling member 51 is coaxially disposed with the pulling part 411, and the inner diameter of the pulling member 51 is smaller than the outer diameter of the pulling part 411. It can be appreciated that when the lifting member 51 moves upward and abuts against the lifting portion 411, the contact surface between the lifting member 51 and the lifting portion 411 is larger, so that the second wind wheel 40 can be lifted more stably, and the problem that the second wind wheel 40 is severely swayed or swayed in the lifting process due to smaller contact area is avoided.

According to the description of the pulling member 51 and the pulling portion 411 above, the second wind wheel 40 can be lifted up as long as the pulling member 51 is driven to move upward in the axial direction of the second output shaft 22 by the driving member 52. The driving member 52 may drive the lifting member 51 to move up and down, for example, the driving member 52 may be a motor, and the motor drives the lifting member 51 to move up and down through a gear, a rack, a screw, a pull rod, and other driving members; for another example, the driving member 52 may be a telescopic driving member 52 (such as a cylinder, a hydraulic cylinder, etc.), where the telescopic driving member 52 directly drives the lifting member 51 to move up and down. Therefore, the specific structure and driving manner of the driving member 52 may require flexible design as long as the up-and-down movement of the pulling member 51 can be smoothly and reliably driven.

As can be appreciated from the above, the wind wheel assembly 100 provided by the present utility model can move upward to disengage from the second output shaft 22 by enabling the second wind wheel 40 to move upward, meanwhile, the pull tab 41 is provided on the second wind wheel 40, the pull tab 41 is provided with a pull portion 411, the pull member 51 in the pull assembly 50 is at least partially suspended below the pull portion 411, and the driving member 52 in the pull assembly 50 can drive the pull member 51 to move upward and downward. When the first wind wheel 30 and the second wind wheel 40 are required to run simultaneously, only the double-shaft motor 20 is required to be started, at this time, because the lifting piece 51 is at least partially suspended below the lifting part 411, the lifting piece 51 is not contacted with the second output shaft 22 or the second wind wheel 40, so that the lifting piece 51 does not influence the rotation of the first wind wheel 30 and the second wind wheel 40, and the double-shaft motor 20 does not need to drive the lifting piece 51 to rotate together, so that the load of the double-shaft motor 20 can be reduced, and the energy consumption is saved. When the first wind wheel 30 is not operated and the second wind wheel 40 is not operated, the lifting member 51 can be driven to move upwards by the driving member 52, and because the lifting member 51 is at least partially positioned below the lifting portion 411, the lifting member 51 can be abutted to the lifting portion 411 in the upward movement process and lift the pull lug 41 and the second wind wheel 40 upwards, and at the moment, the second wind wheel 40 moves upwards and can be disconnected from the second output shaft 22, so that the second wind wheel 40 stops operating. Still further, after the second wind wheel 40 is separated from the second output shaft 22 upwards, when the second wind wheel 40 needs to be connected with the second output shaft 22 again, as long as the pulling member 51 is driven to move downwards by the driving member 52, the pulling lug 41 and the second wind wheel 40 also move downwards until the second wind wheel 40 is connected with the second output shaft 22 again, and then the pulling member 51 is driven to move downwards continuously, so that the pulling member 51 is at least partially suspended below the pulling portion 411.

That is, the wind wheel assembly 100 provided by the utility model can selectively connect or disconnect the second wind wheel 40 from the second output shaft 22, thereby realizing the purpose of only operating one wind wheel, and effectively solving the technical problem that two wind wheels on the existing double-shaft motor 20 can only be opened or closed simultaneously. In addition, the lifting assembly 50 in the utility model does not influence the rotation of the second wind wheel 40, and the double-shaft motor 20 does not need to drive the lifting assembly 50 to rotate together, so that the load of the double-shaft motor 20 can be reduced, and the energy consumption is saved.

Optionally, in an embodiment, referring to fig. 1 to 4, the lifting assembly 50 further includes a first pull rod 53 and a second pull rod 54, where the first pull rod 53 and the second pull rod 54 are respectively connected to the lifting member 51, and the first pull rod 53 and the second pull rod 54 are disposed opposite to each other along a radial direction of the lifting member 51; the driving member 52 drives the pulling member 51 to move up and down in the axial direction of the second output shaft 22 through the first pulling rod 53 and the second pulling rod 54. It can be appreciated that in the present embodiment, because the first pull rod 53 and the second pull rod 54 are opposite along the radial direction of the pull member 51, the stress when the pull member 51 is pulled is more balanced and uniform, so that the condition of shaking during the up-and-down movement of the pull member 51 can be avoided, and the second wind wheel 40 can be lifted or lowered more stably.

The driving member 52 drives the first pull rod 53 and the second pull rod 54 to move up and down in various specific manners, for example, the upper ends of the first pull rod 53 and the second pull rod 54 are connected to a sliding plate, and the driving member 52 drives the sliding plate to move up and down again, so as to drive the first pull rod 53 and the second pull rod 54 to move up and down. For example, two driving members 52 are provided, and the two driving members 52 are telescopic driving members 52 such as a cylinder and a hydraulic cylinder, so as to directly drive the first pull rod 53 and the second pull rod 54 to move up and down respectively. For another example, in an embodiment, referring to fig. 1 to 4, the driving member 52 is a motor, the lifting assembly 50 further includes a first swing link 55 and a second swing link 56, one end of the first swing link 55 is hinged to the first pull link 53, the other end is provided with a first gear 551, and a center of the first gear 551 is connected to the driving member 52; one end of the second swing rod 56 is hinged to the second pull rod 54, a second gear 561 is arranged at the other end of the second swing rod, and the second gear 561 is meshed with the first gear 551. As shown in fig. 2, when the second wind wheel 40 needs to be lifted, the driving piece 52 drives the first gear 551 to rotate, so that the first swing rod 55 swings upwards, and the first swing rod 55 lifts the first pull rod 53; since the second gear 561 is engaged with the second gear 561, when the first gear 551 rotates, the second gear 561 also rotates, and further drives the second swing rod 56 to swing upwards, and the second swing rod 56 lifts the second pull rod 54. That is, after the driving member 52 is started, the first swing link 55 and the second swing link 56 lift the first pull rod 53 and the second pull rod 54 at the same time, so as to lift the lifting member 51 and the second wind wheel 40. When the second wind wheel 40 needs to be lowered, the driving member 52 can rotate reversely. It can be appreciated that, in this embodiment, the first pull rod 53 and the second pull rod 54 are lifted by the first swing rod 55 and the second swing rod 56 which are meshed with each other, so that not only can synchronous movement of the first pull rod 53 and the second pull rod 54 be ensured, but also the situation that the lifting member 51 and the second wind wheel 40 are askew is avoided, and the structure is simple, and slipping and the like are not easy to occur.

Further, in an embodiment, as shown in fig. 4, a first supporting rod 552 is disposed on a side of the first gear 551 facing away from the driving member 52, a first supporting table 57 is disposed on the mounting case 10 at a position corresponding to the first supporting rod 552, and the first supporting rod 552 is rotatably mounted on the first supporting table 57; second support rods 562 are respectively disposed on two sides of the second gear 561 in the axial direction, and a second support table 58 is respectively disposed on the mounting case 10 corresponding to each second support rod 562, and each second support rod 562 is rotatably mounted on the corresponding second support table 58. It will be appreciated that in the present embodiment, by providing the first support table 57 and the second support table 58 to support the first gear 551 and the second gear 561, respectively, the structural strength of the lifting assembly 50 can be improved, deformation or falling due to the heavier weight of the second wind wheel 40 can be avoided, and the second wind wheel 40 can be stably lifted and lowered.

In this embodiment, since the axes of the first gear 551 and the second gear 561 are parallel to each other, the first support base 57 and one of the second support bases 58 are also in a laterally adjacent positional relationship, and the first support base 57 and the adjacent second support base 58 are integrally formed for the sake of simplifying the structure.
