In some embodiments of the present application, as shown in fig. 4, 5 and 6, the hanging cup 11 may include a connection portion 112 and a receiving portion 113; the accommodating portion 113 has an accommodating cavity 1133, the accommodating cavity 1133 has an opening end 1134, and the motor 31 is located in the accommodating cavity 1133; the connection portion 112 is connected to the open end 1134 of the connection housing cavity 1133 and to the air duct assembly 2.

When the ceiling fan mechanism provided by the embodiment of the application is used, the connecting portion 112 is used for being connected with the air duct assembly 2, and the accommodating portion 113 is generally located below the connecting portion 112 and is used for accommodating the motor 31 and facilitating connection of the motor 31 and the wind wheel 32.

Optionally, as shown in fig. 6, the suspension cup 11 further includes a mounting portion 111, the mounting portion 111 being located at a side of the connecting portion 112 remote from the receiving portion 113 for connecting the suspension assembly 1 to a mounting carrier.

Referring to fig. 5, the mounting portion 111 has a ring structure having a certain length in the axial direction of the motor shaft 311, and has a top end opening 1112 and a bottom end opening 1111, wherein the top end opening 1112 of the mounting portion 111 is the top end opening of the hanging cup 11. The accommodating portion 113 has a cup-shaped structure, the bottom 1131 of the accommodating portion 113 is the bottom of the hanging cup 11, and the accommodating portion 113 further has an open end 1134 opposite to the bottom.

Generally, in this embodiment, the cross-sectional area of the cup 11 increases from the bottom 1131 of the cup 11 toward the top opening. As shown in fig. 6, the area of the open end 1134 of the receiving portion 113 is smaller than the area of the bottom end opening 1111 of the mounting portion 111, the open end 1134 of the receiving portion 113 is the portion of the receiving portion 113 having the largest cross-sectional area, and the bottom end opening 1111 of the mounting portion 111 is the portion of the mounting portion 111 having the smallest cross-sectional area, wherein the cross-section is perpendicular to the axial direction of the motor shaft 311.

In some embodiments of the present application, the bottom end opening 1111 of the mounting portion 111 and the open end 1134 of the receiving portion 113 are both located on a set plane, which is perpendicular to the axial direction of the motor shaft 311.

In this case, the connection portion 112 has a ring-shaped plate shape, an inner edge of which is connected to the opening end 1134 of the receiving portion 113, and an outer edge of which is connected to the bottom end opening 1111 of the mounting portion 111. The gland 33 and the duct assembly 2 are located on opposite sides of the connection 112, respectively, and are fixedly connected to the connection 112.

Alternatively, the air duct assembly 2 is connected with the connecting portion 112 through a first screw, and the gland 33 is connected with the connecting portion 112 through a second screw.

Optionally, a third screw passes through the air duct assembly 2, the connection portion 112 and the gland 33 in order to connect the air duct assembly 2, the hanging cup 11 and the gland 33 together.

In some embodiments of the present application, as shown in fig. 7, the ceiling fan mechanism may further include a control assembly 4, where the control assembly 4 is located in an annular space enclosed by the mounting portion 111 and is connected to the mounting portion 111; the control assembly 4 may be used to control the motor 31.

The control assembly 4 may include a control circuit board or the like, which is accommodated in an annular space surrounded by the mounting portion 111 and is connected to the mounting portion 111 through the mounting bracket 12.

Alternatively, the mounting bracket 12 may be located on a side of the control assembly 4 remote from the connection portion 112 and cover at least a portion of the top end opening 1112 of the mounting portion 111.

Alternatively, the control assembly 4 may be screwed to the mounting bracket 12, or the control assembly 4 may be sandwiched between the mounting bracket 12 and the gland 33.

Alternatively, the mounting bracket 12 may be snapped with the mounting portion 111 or attached to the mounting portion 111 by screws.

It should be noted that the function of the control assembly 4 is configured by a skilled person according to actual requirements, and the control assembly 4 may also be used for controlling the lighting mechanism of the fan lamp when the ceiling fan mechanism is applied to the fan lamp, for example.

In some embodiments of the present application, as shown in fig. 8 and 9, the air duct assembly 2 is provided with a mounting opening 2214; the accommodating portion 113 extends into the airflow cavity 21 from the mounting opening 2214, and the mounting portion 111 and the connecting portion 112 are located outside the airflow cavity 21, wherein the connecting portion 112 is overlapped and fixed on the edge of the air duct assembly 2 for enclosing the mounting opening 2214.

The mounting opening 2214 is generally formed in the top of the air duct assembly 2, so that the accommodating part 113 of the hanging cup 11 can extend into the inner cavity of the air duct assembly 2 from the mounting opening 2214, the distance between the hanging cup 11 and the wind wheel 32 is reduced, on one hand, the assembly of the motor shaft 311 and the wind wheel 32 is facilitated, the structure of the hanging fan mechanism is more compact, and on the other hand, the assembly distance between the hanging cup 11 and the wind wheel 32 is shortened, so that the hanging cup 11 has a good positioning effect on the wind wheel 32, and the assembly error is effectively reduced.

The opening area of the mounting opening 2214 is generally equal to or slightly larger than the area of the opening end 1134 of the accommodating portion 113, but smaller than the area of the bottom opening 1111 of the mounting portion 111, so that the connecting portion 112 may overlap the air duct assembly 2, and the connecting portion 112 and the air duct assembly 2 are in surface contact, so that the assembly space of the screw is fully reserved, and when the connection is performed by the screw, the connection between the connecting portion 112 and the air duct assembly 2 is more firm.

In some embodiments of the present application, as shown in fig. 10, the airflow chamber 21 has an air inlet 211, and an orthographic projection of the air inlet 211 along an axial direction of the motor shaft 311 and an orthographic projection of the mounting portion 111 along the axial direction of the motor shaft 311 at least partially overlap; at least a part of the outer wall of the mounting portion 111 is configured to: extends obliquely from the bottom end opening 1111 in a direction approaching the top end opening 1112, wherein the portion closer to the top end opening 1112 is larger in outer diameter.

Illustratively, referring to fig. 10, the air intake 211 is spaced from the mounting opening 2214, and the air intake 211 is disposed around the mounting opening 2214. The wind wheel 32 is located directly below the mounting opening 2214, and the air inlet position of the wind wheel 32 corresponds to the position of the air inlet 211, so that the air inlet flow rate of the ceiling fan mechanism is increased.

However, since the size of the mounting portion 111 above the air inlet 211 is large, the air inlet opening is blocked to some extent, resulting in an influence on the air inlet quantity; if the cross-sectional dimension of the mounting portion 111 is reduced, the strength of mounting with the mounting carrier is affected. In the present embodiment, therefore, as shown in fig. 6, at least a part of the outer wall of the mounting portion 111 is inclined with respect to the connecting portion 112, and the closer the inclination direction is to the tip opening 1112 of the mounting portion 111, the farther from the connecting portion 112 in the radial direction of the motor shaft 311. That is, at least a portion of the outer wall of the mounting portion 111 is flared from the bottom end opening 1111 of the mounting portion 111, wherein the outer wall sectional area at the bottom end opening 1111 is the smallest. Compared with the mode that the outer wall of the mounting part 111 is perpendicular to the connecting part 112, the shielding of the mounting part 111 to the air inlet 211 is obviously reduced and the air inlet amount is improved on the premise of ensuring the mounting strength between the mounting part 111 and the mounting carrier.

In some embodiments of the present application, the blower assembly 3 further includes a gland 33, where the gland 33 is located inside the hanging cup 11 and is connected to the connection portion 112; the motor 31 is sandwiched between the pressing cover 33 and the bottom 1131 of the housing 113.

Alternatively, as shown in fig. 4, a first through hole 1132 is opened at the bottom 1131 of the receiving portion 113, the motor shaft 311 passes through the first through hole 1132, and a gap is provided between the motor shaft 311 and a wall of the first through hole 1132.

The motor 31 provided in this embodiment may be an inner rotor motor 31, where a motor shaft 311 of the inner rotor motor 31 is connected with a rotor, and after the motor 31 is electrified, the motor shaft 311 can rotate around a central axis of the motor shaft 311 under the drive of the rotor.

The wind wheel 32 is driven to rotate by a motor shaft 311. As shown in fig. 4, in this embodiment, the wind wheel 32 is located outside the hanging cup 11, in order to realize connection between the motor shaft 311 and the wind wheel 32, a first through hole 1132 may be formed at the bottom 1131 of the accommodating portion 113, so that the motor shaft 311 may extend out of the hanging cup 11 through the first through hole 1132 and be connected with the wind wheel 32, so as to realize driving of the wind wheel 32. Wherein, because the suspension assembly 1 and the air duct assembly 2 are stationary during the operation of the fan assembly 3, the aperture of the first through hole 1132 needs to be larger than the shaft diameter of the motor shaft 311, so that the motor shaft 311 penetrating through the first through hole 1132 is not contacted with the wall of the first through hole 1132, and the suspension cup 11 and the rotating motor shaft 311 do not interfere with each other.

In this embodiment, the motor 31 may be held down to secure the cup 11. As shown in fig. 4, the pressing cover 33 may be covered at one end of the motor 31 far away from the bottom 1131 of the hanging cup 11 and is fastened to the hanging cup 11, so that the pressing cover 33 and the bottom 1131 of the hanging cup 11 cooperate to clamp the motor 31, so that the motor cannot move relative to the hanging cup 11, and assembly and positioning of the motor 31 on the hanging cup 11 are realized.

Optionally, the connection mode between the gland 33 and the hanging cup 11 may be clamping, riveting or connecting through screws, and the technician may select according to the actual requirement.

In some embodiments of the present application, with continued reference to fig. 4, the fan assembly 3 further includes a damper 34, and the damper 34 may be sandwiched between the motor 31 and the gland 33, and/or the damper 34 may be sandwiched between the motor 31 and the bottom 1131 of the receptacle 113.

The damping member 34 is generally made of soft materials, and is used for preventing noise and vibration generated by rigid collision between the motor 31 and the pressing cover 33 and the hanging cup 11 during operation. For example, the shock absorbing member 34 may be a rubber or silicone gasket.

The wind wheel 32 is generally suspended in the middle of the scroll 22 and there is no contact between the wind wheel 32 and the scroll 22 to avoid interference between the wind wheel 32 and the scroll 22, which remains stationary, while rotating. The wind wheel 32 has a certain gap between the radial direction and the inner wall of the scroll 22 for forming an air duct for allowing the air flow blown out from the wind wheel 32 to pass through and flow to the air outlet 212 of the air flow chamber 21, the air duct circumferentially surrounding the wind wheel 32.

The vortex tongue 23 is disposed in the annular air duct 213, and is used for guiding, collecting and pressurizing the air flow in the annular air duct 213, so as to increase the air supply speed when the air flow flows out from the air outlet 212, and increase the air supply distance of the ceiling fan mechanism.

In some embodiments of the present application, as shown in fig. 12, the scroll 22 may include a first air channel housing 221 and a second air channel housing 222; the first air duct shell 221 is connected with the hanging cup 11, and the air inlet 211 of the airflow cavity 21 is positioned on the first air duct shell 221; the second air duct housing 222 is connected to the first air duct housing 221 by a first fastener 5, the first fastener 5 extending into or through the scroll tongue 23.

Taking the first fastening member 5 as a screw, as shown in fig. 12, screw mounting structures (for example, screw holes) are respectively provided on the first air duct housing 221 and the second air duct housing 222, and the screw can be screwed into the screw mounting structures, so that the first air duct housing 221 and the second air duct housing 222 are fixedly connected together. Because the wind wheel 32 is arranged in the middle of the volute 22, the screw mounting structure needs to avoid the wind wheel 32, and is usually arranged in the annular air duct 213. In order to avoid the influence of the screw mounting structure on the flow direction and the flow rate of the air flow in the annular air duct 213, the screw mounting structure may be provided at the scroll tongue 23, and the screw may be inserted into the scroll tongue 23 to be fixed, or the screw may penetrate through the scroll tongue 23 to be fixed.

Alternatively, the scroll tongue 23 may be connected to the first duct housing 221 or may be connected to the second duct housing 222. Taking the arrangement of the vortex tongue 23 on the first air channel shell 221 as an example, the position on the first air channel shell 221 corresponding to the vortex tongue 23 is provided with a screw hole penetrating through the shell wall of the first air channel shell 221 and the vortex tongue 23, the second air channel shell 222 is provided with another screw hole corresponding to the position, and the screw sequentially penetrates through the screw hole on the first air channel shell 221 and the screw hole on the second air channel shell 222 so as to firmly connect the first air channel shell 221 to the second air channel shell 222.

In some embodiments of the present application, as shown in fig. 13, the first air duct housing 221 includes a fixing portion 2211, a cover portion 2212, and a connection rib 2213; the housing 2212 has a ring-shaped structure; the fixing portion 2211 is located inside the housing portion 2212, and the fixing portion 2211 and the housing portion 2212 are disposed at intervals to enclose the air intake 211; at least a portion of the connection rib 2213 is located in the air intake 211, and connects the fixing portion 2211 and the housing portion 2212 to each other in close proximity to and opposite to the housing wall.

The fixing portion 2211, the connection rib 2213, and the housing portion 2212 are connected in this order in the radial direction of the motor shaft 311. The fixing portion 2211 is annular, an installation opening 2214 is formed on the inner side of the fixing portion 2211, the outer side of the fixing portion 2211 is used for being matched with the housing portion 2212 to enclose one side edge of the air inlet 211, and the fixing portion 2211 is used for being fixedly connected with the hanging cup 11. The housing portion 2212 is configured to cooperate with the second air duct housing 222 to enclose the annular air duct 213, and the scroll tongue 23 and the screw mounting structure are connected to the housing portion 2212. The connection rib 2213 is located between the fixing portion 2211 and the housing portion 2212, and one end thereof is connected to the fixing portion 2211, and the other end thereof is connected to an end wall 22121 of the housing portion 2212 for enclosing the air intake 211, so that at least a portion of the connection rib 2213 is located in the air intake 211 and shields a portion of the air intake 211.

Alternatively, the number of the connection ribs 2213 is plural, and the plural connection ribs 2213 are arranged at intervals along the circumferential direction of the fixing portion 2211 for improving the connection strength between the fixing portion 2211 and the spacing portion. Wherein the air flow can enter the air flow chamber 21 from the gap between the adjacent connection ribs 2213.

Alternatively, each of the connection ribs 2213 has a plate shape and is longitudinally arranged in the air inlet 211 to increase the connection area with the fixing portion 2211 and the housing portion 2212, thereby increasing the connection strength. The "longitudinal arrangement" refers to that the plate surface of the plate-shaped connecting rib 2213 is perpendicular to the annular direction of the fixing portion 2211 and parallel to the opening direction of the air inlet 211, so that the air flow is not blocked by the plate surface of the connecting rib 2213 when flowing into the air inlet 211, and the influence of the connecting rib 2213 on the air inlet volume is reduced.

In some embodiments of the present application, as shown in fig. 14, the connection bead 2213 further has an auxiliary connection portion 22131 connected to the outer wall 22122 of the housing portion 2212 and extending in a direction away from the fixing portion 2211.

For at least one connection rib 2213, the connection rib 2213 may have an auxiliary connection portion 22131 in addition to a portion located in the air inlet 211, and the auxiliary connection portion 22131 may be connected to a portion of the connection rib 2213 located in the air inlet 211, so that the height of the connection rib 2213 is generally higher than that of the first air duct housing 221, that is, the connection rib 2213 has a portion located above the first air duct housing 221, wherein the height direction is along the axial direction of the motor shaft 311.

Alternatively, the auxiliary connection portion 22131 of the at least one connection rib 2213 extends in the radial direction of the motor shaft 311 and is connected with the outer wall 22122 of the housing portion 2212. With the auxiliary connection portion 22131, the connection strength between the fixing portion 2211 and the housing portion 2212 is improved.

In some embodiments of the present application, referring to fig. 15, an end of the housing portion 2212 near the fixing portion 2211 is turned into the airflow chamber 21 to form a flange 22123, and the turning point is smoothly transited.

As shown in fig. 15, the cross section of the flange 22123 is arc-shaped, which can play a role in guiding and collecting the airflow flowing into the air inlet 211 to a certain extent, so that the air inlet is smoother. It will be readily appreciated that the end wall 22121 may be located on the flange 22123 as shown in figures 14 and 15.

In some embodiments of the present application, as shown in fig. 16, the fan assembly 3 further includes an intermediate member 35, and the motor shaft 311 is connected to the wind wheel 32 through the intermediate member 35; wherein the stiffness of the intermediate piece 35 is greater than the stiffness of the wind wheel 32.

Generally, the wind wheel 32 is made of plastic materials, and when the wind wheel 32 is directly connected with the motor shaft 311, the connection part of the wind wheel 32 and the motor shaft 311 is easy to wear in long-term operation, so that slipping occurs between the wind wheel 32 and the motor shaft 311, and the operation is affected. By providing the intermediate member 35 between the wind wheel 32 and the motor shaft 311, the abrasion to the wind wheel 32 can be reduced, and the intermediate member 35 is not easy to abrade because the intermediate member 35 has higher hardness and better abrasion resistance, thereby prolonging the service life of the wind wheel 32. Illustratively, the intermediate member 35 is a metallic material.

Alternatively, the wind wheel 32 may be made of plastic material and obtained by injection molding in a mold in which the intermediate member 35 is placed, so that the wind wheel 32 and the intermediate member 35 are tightly connected and are not easily worn or cracked.

In some embodiments of the present application, as shown in fig. 17, the intermediate member 35 has a second through hole 351; the part of the motor shaft 311 extending out of the hanging cup 11 is provided with a limiting part 312, and the size of the limiting part 312 in the radial direction of the second through hole 351 is larger than the aperture of the second through hole 351; the motor shaft 311 passes through the second through hole 351 and is fastened to the intermediate member 35 by the second fastening member 36, wherein the limiting portion 312 and the second fastening member 36 are respectively located at opposite sides of the intermediate member 35.

Referring to fig. 17, the intermediate member 35 may be sleeved on the motor shaft 311, and its position is limited by a limit portion 312 on the motor shaft 311. The second fastening member 36 may be, for example, a nut, and by providing an external thread on the motor shaft 311, the nut may be screwed to the motor shaft 311 and located on a side of the intermediate member 35 away from the limiting portion 312, so that the nut cooperates with the limiting portion 312 to clamp the intermediate member 35.

Alternatively, the intermediate member 35 is cylindrical, and the diameter of the intermediate member 35 is larger than the dimensions of the limiting portion 312 and the second fastening member 36 in the radial direction of the motor shaft 311, so that the surface contact is made between the limiting portion 312 and the intermediate member 35, and between the intermediate member 35 and the second fastening member 36, and reliability and stability are improved.

In summary, in the ceiling fan mechanism provided in the embodiment of the present application, since the air duct assembly 2 and the fan assembly 3 are connected to the hanging cup 11, the hanging cup 11 can play a role in positioning each part in the air duct assembly 2, and play a role in positioning each part in the fan assembly 3, so that the deviation of the dimension chain between each part when the ceiling fan mechanism is assembled is reduced. In addition, in the fan assembly 3, the inner rotor motor 31 is adopted, and the wind wheel 32 is connected with the motor shaft 311 positioned at the central position of the motor 31, so that the dynamic balance of the wind wheel 32 can be enhanced, compared with the condition that a fan is connected with the outer rotor of the outer rotor motor 31, the shaking of the wind wheel 32 in the rotation process is effectively reduced, and the dynamic balance and stability of the fan assembly 3 are improved.

The embodiment of the application also provides a fan device, which comprises the ceiling fan mechanism of any embodiment.

Wherein when the fan apparatus is a fan light, the fan apparatus may further comprise a lighting mechanism, the lighting mechanism is typically disposed at the bottom of the ceiling fan mechanism, and the air outlet 212 of the airflow chamber 21 is disposed around the lighting mechanism.

By adopting the ceiling fan mechanism, the assembly dimension chain between the air duct assembly 2 and the air duct assembly 3 is shortened, so that the assembly difficulty is reduced, the assembly deviation is reduced, and the assembly efficiency can be improved. In addition, in the fan device provided by the embodiment of the application, since the wind wheel 32 is connected with the motor shaft 311 of the motor 31, which is positioned at the central position, through the intermediate piece 35, the dynamic balance of the wind wheel 32 can be enhanced, the shake and noise in the running process can be reduced, the service performance of the product can be improved, and the service life of the product can be prolonged.
