Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a ceiling fan. Background Technology

[0002] Ceiling fans are widely used in daily life, and they are divided into large-volume and small-volume ceiling fans. Large-volume ceiling fans are mostly used on the ceiling, radiating a large area of ​​space, while small-volume ceiling fans are mostly used in studies or inside mosquito nets, radiating a small area of ​​space. Currently, the mainstream trend in small-volume ceiling fans is to modularize and assemble the largest component, the fan blades. This helps manufacturers save on warehousing and logistics costs. At the same time, consumers can experience the fun of assembly when they receive the product, and it is also more convenient for subsequent storage or carrying when going camping. However, most of the mainstream fan blade disassembly and assembly solutions on the market still use the threaded screwing method of traditional fans. For example, in the fan blade disassembly structure disclosed in CN217682451U, the tightness of the connection between the pressure cap and the base during installation depends entirely on the strength of the human hand. Moreover, the connection between the fan blade and the base is on the protrusion on the end face of the base, and the connection position between the fan blade and the protrusion is located at the far end of the base. Under the same wind force, this patent requires a higher horsepower motor to drive the fan blade to rotate. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a ceiling fan to solve the technical problems mentioned in the background art.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] refer to Figures 1 to 9 :

[0032] This embodiment discloses a ceiling fan, including a fan body 10A, a base 3, and fan blades 4. The fan body 10A is enclosed by an outer shell, which forms a cavity for housing components such as a battery 8 and a control board 9. A ceiling fan hook 11 is installed on the upper end of the outer shell, and a drive mechanism 2 is installed on the lower end of the fan body 10A. The base 3 is connected to the output end 2A of the drive mechanism 2 and is driven by the drive mechanism 2 to rotate. It should be understood that the output end 2A here refers to the end of the drive mechanism 2, such as an output shaft or the end that outputs power for rotation. The fan blades 4 are connected to the base 3 through a detachable fan blade mechanism 2A. The detachable fan blade mechanism 2A includes a plug block 5, a plug slot 6, and a pressure cover 7. The fan blades 4 are provided with plug blocks 5, and one end of the base 3 corresponds to... The plug block 5 is provided with a plug groove 6. The cover 7 includes a screw-in part 71 and a cover part 72. A screw-in locking piece 711 is provided on one side of the screw-in part 71. The base 3 is provided with a screw-in locking hole 712 corresponding to the screw-in part 71, which is rotated and locked in place with the screw-in locking piece 711. The screwing here is a rotation locking or rotation screwing. Unlike the existing technology where the cover 7 is screwed in place, the cover 7 and the base 3 are inserted and rotated to lock in place. This is more stable. The locking has a locking formation limit and is easier to lock in. There is no need to worry about the tightness of the screwing in place depending on the amount of manpower. In addition, the fan blade 4 is directly inserted into the plug groove 6 on the inner side of the end face of the base 3. Its connection position is located near the end of the base 3, which results in higher driving efficiency and less energy loss.

[0033] Specifically, the fan blade 4 is further precisely positioned during installation, while increasing the stability of the installation between the fan blade 4 and the base 3. The inner side of the insertion slot 6 is provided with a positioning block 61, and the insertion block 5 is located at the end of the fan blade 4 and has a positioning groove 51. When the insertion block 5 is inserted into the insertion slot 6, the positioning groove 51 is just locked in place with the positioning block 61. In this way, it is equivalent to the insertion block 5 of the fan blade 4 and the insertion slot 6 of the base 3 being limited both inside and outside when they are inserted, that is, double limiting, which makes the connection between the fan blade 4 and the base 3 tighter.

[0034] Specifically, the screw-on locking hole 712 includes an insertion hole 712a and a locking hole 712b. The insertion hole 712a and the locking hole 712b are interconnected, and the opening diameter of the insertion hole 712a is larger than the opening diameter of the locking hole 712b. A locking plate 712c is provided on one side of the locking hole 712b. The screw-on locking member 711 includes a locking head 711a and a locking block 711b, wherein the locking block 711b is connected to the screw-on part 71. Preferably, the screw-on part 71 is a circular cylindrical body, and the locking head 711a is located in the locking block. The end of 711b forms an angle with the locking block 711b, preferably 90 degrees. When the cover 7 is connected to the base 3, the locking head 711a enters from one side of the insertion hole 712a and enters the inner side of the locking plate 712c after rotation. At the same time, the locking block 711b enters from one side of the insertion hole 712a to one side of the locking hole 712b. Because the cover 7 is installed by screw-on locking, the screw-on locking part 711 also has an arc design. Similarly, the insertion hole 712a and the locking hole 712b are also designed to have arc characteristics.

[0035] Specifically, to prevent the rotating clip 711 from automatically detaching from the base 3 after rotational engagement, and to ensure a more secure connection between the rotating clip and the base 3, a positioning lock head 711c is provided on the inner end face of the clip head 711a, and a positioning lock groove 712d is provided on the inner side of the locking plate 712c corresponding to the position of the positioning lock head 711c. When the clip head 711a rotates into the inner side of the locking plate 712c, the positioning lock head 711c and the positioning lock groove 712d engage and lock each other. Through this interlocking action, locking is achieved, and the base 3 and the pressure cover 7 cannot automatically detach. In addition, it should be understood that the rotation direction of the base 3 should be designed to be opposite to the installation direction of the pressure cover 7 and the rotating clip. This design ensures that the rotating clip always rotates in the locking direction.

[0036] Specifically, the driving mechanism 2 is a motor, which includes a coil 21, a magnetic ring 22, and an inner shaft ring 23. The inner shaft ring 23 is provided on the inner side of the coil 21, and the magnetic ring 22 is sleeved on the outer side. The inner side of the base 3 is provided with a nesting cavity 31. The outer periphery of the magnetic ring 22 is nested and fixed to the wall of the nesting cavity 31 of the base 3. The lower end of the fan body 10A is provided with a plug-in protrusion 101. The plug-in protrusion 101 is plugged and fixed to the inner shaft ring 23. When the coil 21 is energized, the magnetic ring 22 outside the coil 21 rotates, thereby driving the base 3 to rotate.

[0037] Specifically, the bottom of the nested cavity 31 is provided with a shaft socket 311, the inner side of the shaft socket 311 is provided with a shaft insertion hole 311a, the inner side of the insertion protrusion 101 is provided with a limiting shaft cavity 101a, the limiting shaft 102 is inserted downward into the shaft insertion hole 311a from the upper end of the limiting shaft cavity 101a, and a copper ring 103 is also sleeved on the outer side of the limiting shaft 102.

[0038] Specifically, the inner wall of the inner shaft ring 23 is provided with a positioning groove 231, and the outer side of the insertion convex shaft 101 is provided with a positioning block 101b corresponding to the positioning groove 231.

[0039] During installation, first, insert or press the magnetic ring 22 into the side wall of the nested cavity 31 of the base 3 and tighten it. Then, place the coil 21 into the magnetic ring 22. Next, insert the insertion convex shaft 101 of the fan body 10A downwards and position it in relation to the inner shaft ring 23 of the coil 21 and tighten it. Finally, insert the limiting shaft 102 downwards from the limiting shaft cavity 101a side of the insertion convex shaft 101 and into the shaft insertion hole 311a of the base 3. Finally, put the copper ring 103 onto the limiting shaft 102 to complete the installation. In this structure, after the coil 21 is energized, the outer magnetic ring 22 rotates around the coil 21 (existing technology). Then, the rotation of the magnetic ring 22 causes the base 3 to rotate, and the rotation of the base 3 drives the fan blade 4 below to rotate, thus completing the blowing. The synchronous rotation of the base 3 also drives the middle limiting shaft 102 to rotate. The limiting shaft 102 is because... It extends upward from one side of the base 3 into the insertion protrusion 101 of the fan body 10A. Therefore, it can be used to prevent the coil 21 from rotating or shaking with the magnetic ring 22 or the magnetic ring 22 from rotating with the base 3. On the other hand, it can also be used as a connection limit between the base 3 and the fan body 10A. When the base 3 is pulled down, the base 3 cannot be pulled down directly because of the limiting shaft cavity 101a of the copper ring 103. It can also be used as a mechanism to prevent the base 3 from falling off the fan body 10A. In the design, the bottom of the limiting shaft cavity 101a of the insertion protrusion 101 needs to be designed so that the limiting shaft 102 can pass through only. The copper ring 103 is restricted in the limiting shaft cavity 101a, and the copper ring 103 is fixed to the limiting shaft 102. The bottom of the limiting shaft 102 is fixedly inserted into the base 3.

[0040] Specifically, the inner side of the fan body 10A is also provided with a battery 8 and a control board 9, the outer side of the control board 9 is provided with a control switch 10, and the upper end of the fan body 10A is provided with a ceiling fan hook 11.

[0041] In another optional embodiment, the drive mechanism 2 is a motor, and a shaft connection hole (not shown) is provided on one side of the fan body 10A. The output shaft of the motor is engaged with the shaft connection hole, and the base 3 is fixedly connected to the outside of the motor. In this embodiment, the motor body is connected to the base 3, driving the base 3 to rotate, while the actual output shaft of the motor is fixedly connected to the fan body 10A.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
