Detailed Embodiment

[0032] Next, the detailed embodiment of the present utility model will be described with reference to the accompanying drawings of the specification.

[0033] As a specific embodiment, the ceiling suspension structure of the ceiling fan device according to the embodiment of the present utility model includes a motor 1, an outer cover 3, and a ceiling suspension 2 for fixedly connecting to the ceiling of a room. It should be noted that the ceiling of a room is the usual installation position of a ceiling fan, and it also includes the ceiling outdoors.

[0034] The motor 1 includes a rotary output end 11. The rotary axis line of the rotary output end 11 is vertical, and a blade 119 is connected to the rotary output end 11. It is easy to understand that the rotary output end 11 drives the blade 119 to rotate to generate a vertical blowing wind, and this blowing wind is usually from top to bottom.

[0035] The ceiling suspension 2 is cylindrical as a whole.

[0036] Both the top end and the bottom end of the outer cover 3 are open, and the top opening of the outer cover 3 is circular when viewed from above. Usually, the bottom opening of the outer cover 3 is also circular when viewed from above; for example, the diameters of the top opening and the bottom opening of the outer cover 3 are equal, so that the inner cavity of the outer cover 3 is cylindrical (this embodiment is not shown in the drawings).

[0037] A locking groove 21 is provided on the side surface of the ceiling suspension 2 around the rotary axis line of the rotary output end 11. The locking groove 21 is L-shaped and communicates with the outside from the bottom end of the ceiling suspension 2. As Figure 6 shown, the bottom wall of the locking groove 21 is inclined relative to the horizontal plane to form a bottom wall height difference 211. A plurality of elastic top teeth 212 are provided on the bottom wall of the locking groove 21. For example, the cross-section of the top tooth 212 is triangular, and the apex angle of this triangle is an obtuse angle. The cross-section of the top tooth 212 can also be trapezoidal, semi-circular, etc. It is easy to understand that the connection lines between the apex angles of the respective top teeth 212 are also inclined relative to the horizontal plane along with the bottom wall of the locking groove 21. It is easy to understand that there are at least two inner convex columns 31 hereinafter, and the locking groove 21 is used for cooperation with the inner convex columns 31. Therefore, the number of the locking grooves 21 is equal to or greater than the number of the inner convex columns 31.

[0038] At least two inner convex columns 31 are fixedly provided on the inner side wall of the outer cover 3. For example, the inner convex columns 31 are protrusions formed by welding or riveting.

[0039] The inner convex columns 31 respectively abut against the bottom wall of the locking groove 21 and are located between two adjacent top teeth 212, so that the top opening of the outer cover 3 fits with the ceiling suspension 2 and the top end of the outer cover 3 abuts against the ceiling of the room.

[0040] The motor 1 is fixedly connected to the ceiling suspension 2 so that the outer cover 3 surrounds the motor 1; therefore, only the outer cover 3 can be seen between the blade 119 and the ceiling of the room, achieving the ceiling installation effect.

[0041] The working principle is as follows: The ceiling suspension plate 2 is fixed on the ceiling of the room, and then the motor 1 is fixedly connected to the ceiling suspension plate 2. The specific implementation manners of fixing the ceiling suspension plate 2 on the ceiling of the room and fixedly connecting the motor 1 to the ceiling suspension plate 2 will be described later.

[0042] Then, the outer cover 3 is moved upward so that the inner convex column 31 enters the locking groove 21 from the opening at the bottom end of the locking groove 21 on the ceiling suspension plate 2 (i.e., the opening that enables the bottom end of the ceiling suspension plate 2 to communicate with the outside), and then the outer cover 3 is rotated until the inner convex column 31 contacts the pressing teeth 212 on the bottom wall of the locking groove 21. Then, the outer cover 3 is continuously rotated so that the inner convex column 31 passes over the pressing teeth 212 until the top end of the outer cover 3 abuts against the ceiling of the room. At this time, the inner convex column 31 remains between two adjacent pressing teeth 212, keeping the outer cover 3 in its rotated position. At this time, since there are more than two inner convex columns 31, the entire circumference of the top end of the outer cover 3 can be attached to the ceiling of the room to ensure the ceiling suction effect; the inner convex column 31 abuts against the bottom wall of the locking groove 21, making the ceiling suspension plate 2 tend to move downward, which can ensure that the suspension plate 23 is not prone to shaking relative to the ceiling of the room and prevent the suspension plate 23 from hitting the ceiling of the room to generate noise due to the vibration generated when the motor 1 operates.

[0043] As one of the specific implementation manners, the ceiling suspension plate 2 includes a suspension plate 23 and a chuck 22 provided with a central hole 221. The chuck 22 is detachably and fixedly connected to the suspension plate 23, and the locking groove 21 is provided on the chuck 22. It is easy to understand that the chuck 22 and the suspension plate 23 enclose to form the locking groove 21, and the top wall of the locking groove 21 is the suspension plate 23. The suspension plate 23 is made of metal and is provided with ceiling connection holes 231, such as being made of iron plate and formed by stamping. Fasteners such as screws pass through the ceiling connection holes 231 and are screwed into the ceiling of the room to fix the suspension plate 23 on the ceiling of the room to ensure the strength and load-bearing capacity of the suspension plate 23; the chuck 22 is made of plastic and has elasticity to utilize the elasticity of the bottom wall of the locking groove 21 to ensure the ceiling suction effect of the outer cover 3 and that the suspension plate 23 is not prone to shaking relative to the ceiling of the room.

[0044] As one of the specific embodiments, it further includes a motor hanger 12. The motor hanger 12 extends upward to form a connecting ear 121. The motor hanger 12 is fixedly connected to the top end of the motor 1 by screws (not shown in the drawings). The motor hanger 12 is also provided with a motor hanger notch 122. When viewed from below, a part of the connecting ear 121 is located within the motor hanger notch 122. It should be understood that if the motor hanger 12 is first fixedly connected to the hanging plate 23, and then the top end of the motor 1 is fixedly connected to the motor 1 by screws or the like, since the distance between the motor 1 of the ceiling-mounted ceiling fan and the ceiling of the room is relatively small, when rotating the screw with a screwdriver or the like, the screwdriver or the like will be interfered by the ceiling of the room and it will be rather inconvenient. Therefore, as described above, after the hanging plate 23 is fixed to the ceiling of the room, the whole of the motor hanger 12 and the motor 1 is moved upward. When the screw passes through the connecting ear 121 and the hanging plate 23 in sequence for fixed connection, it is easier for the screwdriver to pass through the motor hanger notch 122 to rotate the screw, which is convenient for the operation of installing the motor 1.

[0045] As one of the specific embodiments, the two connecting ears 121 are symmetrically arranged around the rotation axis of the rotation output end 11. It is easy to understand that the central angle corresponding to the two connecting ears 121 is 180 degrees. The hanging plate 23 is provided with more than four groups of even-numbered threaded holes 232, and the even-numbered threaded holes 232 are rotationally symmetric around the rotation axis of the rotation output end 11. It is easy to understand that there must be two groups of threaded holes 232 among the groups of threaded holes 232, and the central angle corresponding to the two groups of threaded holes 232 is also 180 degrees. The chuck 22 is provided with through holes (not marked in the drawings) corresponding to the threaded holes 232. The screw passes through the connecting ear 121, the through hole of the chuck 22 and the two groups of threaded holes 232 with a central angle of 180 degrees in the threaded holes 232 for threaded connection. As Figure 6 shown, the hanging plate 23 is provided with four groups of threaded holes 232, and each group of threaded holes 232 has two threaded holes 232. Passing the screw through any two through holes of the chuck 22 with a central angle of 180 degrees and screwing it into the corresponding threaded holes 232 of the hanging plate 23 can fixedly connect the chuck 22 and the hanging plate 23 to realize the assembly of the ceiling-mounted hanging plate 2; the remaining two through holes of the chuck 22 are for the screw to pass through the connecting ear 121 and screw into the threaded holes 232. The threaded holes 232 of the hanging plate 23 are used for the assembly of the ceiling-mounted hanging plate 2 and the fixed connection of the connecting ear 121 at the same time, and there is no need to limit the rotation angle of the motor hanger 12 relative to the hanging plate 23, which is rather convenient.

[0046] As one of the specific embodiments, a receiving space 223 is formed at the bottom end of the chuck 22. The receiving space 223 corresponds to the through hole of the chuck 22. It is easy to understand that the receiving space 223 is also rotationally symmetric around the rotation axis of the rotation output end 11; the connecting ear 121 abuts against the top surface of the receiving space 223. It can further reduce the overall thickness of the ceiling-mounted hanging plate 2 and the motor hanger 12.

[0047] As one of the specific embodiments, the chuck 22 includes a holding portion 222 that abuts against the hanging plate 23. The outer edge of the holding portion 222 extends upward to form a positioning edge 224, and the positioning edge 224 fits against the outer edge of the hanging plate 23. This can ensure that the axes of the chuck 22 and the hanging plate 23 are coaxial, facilitating the assembly of the ceiling-suspended hanging plate 2.

[0048] As one of the specific embodiments, the outer edge of the hanging plate 23 extends upward to form an outer folding edge 234. This can further improve the strength of the hanging plate 23.

[0049] As one of the specific embodiments, the hanging plate 23 is made of a metal plate; the hanging plate 23 is provided with a middle protrusion 233, and the threaded holes 232 are formed by punching, and each threaded hole 232 is located between the middle protrusions 233 provided on the hanging plate 23. The hanging plate 23 can be made by stamping a metal plate, which is beneficial to reducing costs.

[0050] As one of the specific embodiments, the one of the tightening teeth 212 that is closest to the opening of the locking groove 21 at the bottom end of the ceiling-suspended hanging plate 2 is an anti-detachment tooth 213, and the anti-detachment tooth 213 is higher than the adjacent tightening teeth 212. It is easy to understand that the anti-detachment tooth 213 is located at the lowest point of the bottom wall of the locking groove 21. This can limit the detachment of the inner convex column 31 from the locking groove 21 and improve safety.
