The outer rotor motor 13 includes a hollow stator shaft 132 and a rotor 131 wound around the outside of the hollow stator shaft 132. After the outer rotor motor 13 is started, the hollow stator shaft 132 is fixed, and the rotor 131 rotates about the hollow stator shaft 132 as a rotation axis. The wind wheel 12 is directly connected with the rotor 131, so that the wind wheel synchronously rotates under the driving of the rotor 131 to bring airflow; both ends of the hollow stator shaft 132 extend out of the rotor 131 and are connected to the suspension mechanism 2 and the illumination mechanism 3, respectively.

In the fan lamp, power supply leads of the outer rotor motor 13 and the lighting mechanism 3 are led out from the suspension mechanism 2 so as to be connected with an external circuit to take power. Wherein, the control component 31 of the illumination mechanism 3 is installed on the suspension mechanism 2 and electrically connected with the light emitting component 32 through the connecting wire 33 to control the light emitting component 32 to emit light for illumination. One end of the connection line 33 is connected to the control unit 31, and the other end thereof can pass through the hollow stator shaft 132 of the external rotor motor 13 and is connected to the light emitting unit 32. Compare in the outside wire winding from the wind channel among the correlation technique, the scheme of this embodiment is direct from the inside threading of the stator axle of motor, consequently reduces the wire winding distance of connecting wire 33, and the wiring is succinct more and reliable, can also avoid intertwining between the connecting wire 33, has improved the security.

In some embodiments of the present application, the illumination mechanism 3 further includes a connector 34, and the connector 34 has a first opening 341. The connector 34 is connected to the hollow stator shaft 132, and an orthographic projection of the hollow stator shaft 132 on the connector 34 overlaps with the first opening 341, the connecting line 33 passes through the overlapping area, and the light emitting assembly 32 is connected to the connector 34.

The connector 34 is used to connect the light emitting assembly 32 to the hollow stator shaft 132. The connecting member 34 is provided with a first opening 341, the first opening 341 corresponds to the central through hole of the hollow stator shaft 132, that is, there is an overlapping region between the orthographic projection of the hollow stator shaft 132 on the connecting member 34 and the first opening 341, so that the connecting wire 33 passing through the hollow stator shaft 132 can pass through the first opening 341 and be connected to the light emitting element 32. Here, the projection plane of the hollow stator shaft 132 is perpendicular to the axis of the hollow stator shaft 132, and may also be understood as a plane where the open end of the first opening 341 is located.

Fig. 14 shows a structure of a connector. Referring to fig. 14, the connection member 34 includes a connection plate 342, and a first outer edge portion 343 connected to an edge of the connection plate 342, the first outer edge portion 343 being protruded toward the outer rotor motor 13 with respect to the connection plate 342. Illustratively, the connection plate 342 is in a triangular star shape, and the connection plate 342 has a recess 3421 in a central region, and the recess 3421 is farther from the outer rotor motor 13 than other portions on the connection plate; the first opening 341 is opened in the center of the depression 3421, and a second outer edge part 344 is connected to the edge of the first opening 341; a third opening 345 is opened in a middle region of each of the three corners of the connection plate 342, a third outer edge 346 is further connected to an edge of the third opening 345, both the second outer edge 344 and the third outer edge 346 protrude toward the outer rotor motor 13 with respect to the connection plate 342, and the height of the second outer edge 344 is higher than that of the first outer edge 343 and the third outer edge 346. The third opening 345 serves to reduce the self weight of the link 34, and the first, second, and third

outer edge portions

343, 344, and 346 are connected to each other by ribs to increase the strength of the link 34.

In some embodiments of the present application, as shown in fig. 4, the outer sidewall of the second end of the hollow stator shaft 132 is externally threaded; the lighting mechanism 3 includes a nut 35, and the nut 35 is screwed with the hollow stator shaft 132 at a side of the connecting member 34 away from the rotor 131, so that the connecting member 34 is interposed between the stator sleeve of the outer rotor motor 13 and the nut 35.

The nut 35 has an internal thread, and the internal thread of the nut 35 is capable of being screwed with the external thread of the hollow stator shaft 132. When the hollow stator shaft 132 is assembled, the first opening 341 penetrates through the hollow stator shaft 132 to sleeve the connecting piece 34 on the hollow stator shaft 132, and then the connecting piece 34 is screwed to a position on the hollow stator shaft 132, where the connecting piece 34 can be clamped, so as to fasten the connecting piece 34.

It should be noted that the connection member 34 is actually interposed between the stator sleeve and the nut 35. As shown in fig. 4, the second outer edge 344 of the connecting member 34 corresponds to a position of the stator sleeve, when the connecting member 34 is clamped, the second outer edge 344 abuts against the stator sleeve, and the other parts of the connecting member 34 except the second outer edge 344 correspond to the position of the rotor 131 and have a larger distance from the rotor 131, so as to avoid contacting the rotor 131 to generate friction and influence on the rotation of the rotor 131.

With continued reference to fig. 4, in some embodiments, the outer side wall of the first end of the hollow stator shaft 132 is also provided with an external thread, and correspondingly, the suspension mechanism 2 is provided with an internal thread, so that the suspension mechanism 2 and the first end of the hollow stator shaft 132 are also connected by a thread fit, and the connection manner is simple and reliable.

In some embodiments of the present application, as shown in fig. 5, the fan mechanism 1 includes a first air duct member 111 and a second air duct member 112 located inside the fan housing 11; the first air duct member 111 and the second air duct member 112 are both arranged around the air outlet of the wind wheel 12, wherein the first air duct member 111 is adjacent to the top of the wind wheel 12, the second air duct member 112 is adjacent to the bottom of the wind wheel 12, and an air duct space 113 surrounding the air outlet is formed between the first air duct member 111 and the second air duct member 112; the first air duct member 111 and the second air duct member 112 are close to each other at respective ends thereof remote from the wind rotor 12 with a gap 114 therebetween, and the gap 114 is used for discharging the airflow blown out by the wind rotor 12.

In the present embodiment, the top of the wind rotor 12 refers to the portion located above, i.e., closer to the suspension mechanism 2, and the bottom refers to the portion located below, i.e., closer to the light emitting assembly 32.

The fan mechanism 1 that this application embodiment provided is the hidden air-out mechanism of blade, and wind wheel 12 is located fan housing 11's inside, and correspondingly, wind channel space 113 also forms in fan housing 11's inside. As shown in fig. 5, the top of the fan housing 11 is an air inlet grille, through which an air inlet of the wind wheel 12 is communicated with the outside; the air duct space 113 is formed by the first air duct member 111 and the second air duct member 112, and is located between the air outlet of the wind wheel 12 and the inner wall of the air duct housing, and is annular. Through the combination of the wind wheel 12, the first air channel member 111 and the second air channel member 112, the airflow is sucked from the top of the fan mechanism 1, and then blown to the inner wall of the first air channel member 111 by the wind wheel 12 and then blown out through the annular air channel outlet, so that annular wind is formed and blown off to the ground, and the outlet air is softer.

Referring to fig. 5, the first air duct member 111 and the second air duct member 112 enclose an air duct space 113 along the radial direction of the wind wheel 12, and as the first air duct member 111 and the second air duct member 112 are farther away from the wind wheel 12 and closer to each other, the formed air duct space 113 is farther away from the wind wheel 12 in the radial direction, the cross-sectional area is smaller, thereby being beneficial to concentrating the air flow blown by the wind wheel 12 and improving the air outlet efficiency and the air supply distance of the air duct outlet. The air duct outlet is defined by an end of the first air duct member 111 away from the wind wheel 12 and an end of the second air duct member 112 away from the wind wheel 12, and the outlet direction is directed downward so that the air flow is blown to a user located below the fan lamp.

As shown in fig. 6, in some embodiments of the present application, a plurality of air deflectors 115 are disposed on an inner wall of the first air channel member 111, and the air deflectors 115 are used for guiding and collecting the airflow blown by the wind rotor 12.

Alternatively, the air guide member 115 and the first air channel member 111 may be formed separately and connected together, for example, by clamping, screwing, bonding, etc.; alternatively, the air guide 115 and the first air duct member 111 may be integrally formed.

Fig. 7 is a schematic sectional view (other structures are omitted) showing the arrangement of the first air duct member 111 and the wind wheel 12 in the fan mechanism 1, and as shown in fig. 7, each of the air guides 115 is arranged obliquely on the inner wall of the first air duct member 111, and the arrangement direction of the air guide surfaces of the plurality of air guides 115 is the same as the rotation direction of the wind wheel 12. Therefore, the airflow blown out by the wind wheel 12 can impact on the flow guiding surface of the flow guiding element 115 and is guided and pressurized by the flow guiding element 115, so that the degree of the airflow diverging to the periphery is reduced, the airflow is more concentrated, the flow guiding element 115 can achieve the effect of guiding and gathering the diverging airflow blown out by the wind wheel 12, and the air supply amount and the air supply distance of the air duct outlet are further increased.

Optionally, each air guide 115 has a chord tangent angle on the first air duct member 111 greater than 15 ° and less than 90 °. As shown in fig. 7, the tangential angle of the air guide 115 on the first air duct member 111 may be represented by α,15 ° < α < 90 °, where the tangential angle refers to the angle between the portion of the air guide 115 in contact with the first air duct member 111 and the tangent to the first air duct member 111 at the point of contact. Illustratively, the chord tangent angle α may be 30 °, 40 °, 50 °, or 60 °.

In some embodiments of the present application, the distance between the flow guide 115 and the blades 126 of the wind rotor 12 is 0.3 to 0.7 times the width of the tunnel space 113. Referring to fig. 7, the distance L between the guide 115 and the blades 126 refers to a minimum distance between the guide 115 and the outer edges of the blades 126, and the width D of the air chute space 113 refers to a minimum distance between the end of the guide 115 connected to the first air chute member 111 and the outer edges of the blades 126.

In the embodiment of the present application, the distance L between the air guide 115 and the blades 126 of the wind rotor 12 may be determined according to the diameter of the wind rotor 12 and the size of the wind channel outlet. When the distance L between the flow guide 115 and the blades 126 of the wind wheel 12 is too large, the flow guide effect is poor; when the distance L between the air guide member 115 and the blades 126 of the wind wheel 12 is too small, the air output is reduced, and the air output distance is reduced, thereby affecting the air output effect. In some embodiments of the present application, the number of flow guides 115 is greater than or equal to the number of blades 126 of the wind rotor 12. Alternatively, the number of the flow guide 115 may be 1.1 to 3 times the number of the blades. In a certain range, the more the number of the flow guide pieces is, the more uniformly the airflow flowing out of the blades is divided, and the better the flow guide effect is. However, when the number of the flow guiding elements is too large, the airflow in the air duct space is easily blocked, so that the air volume is reduced, the airflow velocity is reduced, the air outlet distance is reduced, and the air outlet effect is affected.

Referring to fig. 7 and 8, in the present embodiment, at least one of the plurality of fluid guides 115 is provided with a first connection structure 1151 on the fluid guide 115; a second connection structure 1121 is disposed at a position of the second air duct member 112 corresponding to the first connection structure 1151, and the second connection structure 1121 is connected to or matched with the first connection structure 1151.

In one example, the first connector 34 and the second connector 34 are connected to each other. The first connection structure 1151 and the second connection structure 1121 may be one and the other of a hook and a slot, respectively, and the hook is snapped into the corresponding slot when assembled, so that the first air duct member 111 and the second air duct member 112 are connected together.

In another example, as shown in FIG. 8, the first connector 34 and the second connector 34 mate. The first connection structure 1151 is a screw hole penetrating the first air duct member 111 and the air guide 115 in the height direction, the second connection structure 1121 is a screw hole opened in the second air duct member 112, and the first air duct member 111 and the second air duct member 112 are connected together by screws installed in the first connection structure 1151 and the second connection structure 1121. The thickness of the fluid guiding element 115 provided with the first connection structure 1151 is greater than the thickness of the other fluid guiding elements 115, so as to ensure the connection strength of the first connection structure 1151.

Optionally, the rotor 12 is a pitched rotor 12, and the number of blades 126 of the rotor 12 is odd. Compared with the forward inclined wind wheel 12, the backward inclined wind wheel 12 has lower noise and larger air output. The number of the blades 126 is set to be an odd number to reduce the resonance sound, and the number of the blades 126 may be nine, for example.

As shown in fig. 9 and 10, in some embodiments of the present application, the light emitting assembly 32 includes a light source fixing member 321, a light emitting element 322, and a lamp cover 323; the middle part of the light source fixing part 321 is connected with the connecting part 34, and the edge part of the light source fixing part 321 is connected with one end of the second air channel component 112 close to the wind wheel 12 in a matching way; the light emitting element 322 is installed on the side of the light source fixing member 321 away from the wind wheel 12; the lampshade 323 is connected with one end of the second air channel member 112 far away from the wind wheel 12 in a matching way.

The light source fixing member 321 is used to fix and fix the light emitting element 322. Illustratively, the light source fixing member 321 may be a lamp panel, and one side of the lamp panel facing away from the fan mechanism 1 is a mounting surface on which mounting positions of the plurality of light emitting elements 322 are uniformly or regularly arranged. As shown in fig. 9, the light source fixing member 321 is connected to the side of the connecting member 34 facing the light emitting assembly 32, for example, by screwing or clipping. An escape opening is formed in the center of the light source fixing member 321 for escaping the hollow stator shaft 132 and the nut 35, and the connection wire 33 extending from the hollow stator shaft 132 may further pass through the escape opening to be connected to the light emitting element 322 on the side of the mounting surface of the lamp panel.
