Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and specifically to a ceiling fan that is easy to assemble and disassemble. Background Technology

[0002] When electric fans are used at home, the usage time is relatively concentrated, generally only in summer; therefore, ceiling fans are often idle all year round, and dust easily accumulates on their blades and is difficult to clean.

[0003] For example, Chinese patent CN111749916B discloses a ceiling fan that uses a temperature and humidity sensor to detect the current air temperature and humidity. At the same time, the control circuit board uses the detected temperature and humidity data to further adjust the motor speed and switching time of the ceiling fan.

[0004] However, traditional ceiling fans are relatively complicated to install and disassemble, and it is not convenient to remove the fan blades and protect the main body from dust when not in use; the fan blades of traditional ceiling fans are also difficult to fold and store, taking up a lot of space.

[0005] Based on this, the present invention designs a ceiling fan that is easy to assemble and disassemble to solve the above problems. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A ceiling fan that is easy to assemble and disassemble includes a fixed mounting base 1 and a rotating mounting base 2, and also includes a detachable fan blade assembly 3 and a dustproof structure 4;

[0033] A protective box 11 is fixedly installed at the bottom of the fixed mounting base 1, and a rotating mounting base 2 is rotatably installed at the bottom of the protective box 11; a motor for driving the rotating mounting base 2 is fixedly installed inside the protective box 11; a detachable fan blade assembly 3 is installed on the rotating mounting base 2; a dustproof structure 4 for dustproofing the rotating mounting base 2 after the detachable fan blade assembly 3 is removed is also installed on the rotating mounting base 2.

[0035] In this embodiment, when the easily detachable ceiling fan is working normally, the fan blade module 32 can be folded and stored when the fan is not in use. Then, the dustproof structure 4 covers the mounting module 31 to prevent dust from falling inside. The dustproof structure 4 is then secured with the fastening structure 33, providing dust protection for the non-removable parts. The structure of the fan blade module 32 facilitates its storage. When the ceiling fan is needed in summer, the dustproof structure 4 is removed, and the fan blade module 32 is installed on the mounting module 31. The fastening structure 33 then secures the fan blade module 32. Thus, the fan blade module 32 is not... It is prone to dust accumulation, and when the fan blade module 32 is damaged, there is no need to replace the entire ceiling fan; only the corresponding parts need to be disassembled for repair or replacement, reducing maintenance costs. The fan blade module 32 can be set to various sizes, which can be switched according to usage. For example, according to usage needs, different sized fan blade modules 32 can be disassembled and reinstalled in different rooms to adapt to changes in home layout and usage needs. During use, the motor in the protective box 11 drives the rotating mounting base 2 to rotate, and the rotating mounting base 2 drives the fan blade module 32 to rotate through the mounting module 31. The mounting module 31 and the fastening structure 33 ensure the installation stability of the fan blade module 32 while allowing it to be disassembled.

[0036] Example 2: In some embodiments, as a preferred embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the mounting module 31 includes a polygonal mounting platform 311 and a shielding frame 312.

[0037] The polygonal mounting platform 311 is set to be hexagonal;

[0038] The shielding frame 312 has six support slots 315 evenly spaced in a circular array on its surface.

[0039] The fan blade module 32 includes a main module and a combination module. The main module is installed in the mounting slot 313, and the combination module is installed on the main module.

[0040] The main module includes mounting plates 321, limiting plates 322, and blades 323. Six mounting plates 321 are provided, and adjacent mounting plates 321 are rotatably connected. The length of the mounting plates 321 is the same as the length of the mounting grooves 313. The mounting plates 321 are inserted into the shielding frame 312. The limiting plates 322 are fixedly installed on the upper side of the mounting plates 321, and blades 323 are fixedly installed on the sides of the mounting plates 321. The blades 323 are engaged with the support grooves 315. When multiple mounting plates 321 are inserted into the mounting grooves 313, the multiple mounting plates 321 are evenly distributed in a circumferential array, and the blades 323 on the mounting plates 321 are also evenly distributed in a circumferential array. When the mounting plates 321 are not inserted into the mounting grooves 313, the multiple mounting plates 321 are distributed in a long chain-like pattern.

[0041] The combined module includes an arc-shaped fastening plate 324 and a plug plate 325. The arc-shaped fastening plate 324 is fixedly installed on the inner side of the limiting plate 322, and multiple plug plates 325 are fixedly installed on the inner side of the mounting plate 321. The plug plates 325 are inserted into the slots 314. When the mounting plate 321 is inserted into the mounting groove 313, the arc-shaped fastening plates 324 are combined into a circle, and at this time the threads on the outer sides of the multiple arc-shaped fastening plates 324 are aligned.

[0042] The fastening structure 33 includes an annular fastening bracket 331, which is sleeved on the outside of the protective box 11; the inner side of the annular fastening bracket 331 is provided with a threaded groove that is used to cooperate with the thread on the outside of the arc-shaped fastening plate 324.

[0043] The fastening structure 33 also includes limiting posts 332. Multiple sets of limiting posts 332 are evenly fixedly installed on the polygonal mounting platform 311. Limiting grooves 333 are provided on the limiting plate 322, and the limiting plate 322 is inserted into the limiting grooves 333.

[0044] like Figure 4 and Figure 5 As shown, the dustproof structure 4 includes a dust cover 41 and a semi-circular combined plate 43.

The annular fastening bracket 331 is threadedly connected to the combined semi-circular combined plate 43.

[0045] In this embodiment, when the detachable fan blade assembly 3 and the dustproof structure 4 are working normally, in the non-use state, the relative positions of the multiple mounting plates 321 are adjusted so that the blades 323 on the mounting plates 321 face the same side, thereby making it easier to store the blades 323; two dust covers 41 are placed on both sides of the stepped groove 42, at which time the two dust covers 41 combine to form a closed space and cover the outside of the polygonal mounting platform 311, the shield 312, the mounting groove 313, the slot 314, and the support groove 315, thereby achieving dust protection for the polygonal mounting platform 311, the shield 312, the mounting groove 313, the slot 314, and the support groove 315; the mounting plates 321 are rotatably connected, making it easy to adjust and store the mounting plates 321. To prevent the loss of a single mounting plate 321, multiple mounting plates 321 are arranged in a circular array around the outside of the polygonal mounting platform 311. At this time, the insert plates 325 on the mounting plates 321 are aligned with the slots 314, and multiple mounting plates 321 are inserted into the mounting grooves 313 and the insert plates 325 are inserted into the slots 314 until the blades 323 contact the bottom of the support grooves 315. At this time, the limiting post 332 on the polygonal mounting platform 311 is inserted into the limiting groove 333 on the limiting plate 322. Multiple arc-shaped fastening plates 324 are combined into a circle, and the threads on the arc-shaped fastening plates 324 are aligned. The annular fastening frame 331 is rotated, and the multiple arc-shaped fastening plates 324 are fixed by the threaded groove inside the annular fastening frame 331 and the threads on the outside of the arc-shaped fastening plates 324.

[0046] Example 3: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 3 As shown, an auxiliary lighting module 5 is also installed at the bottom of the rotating mounting base 2;

[0047] The auxiliary lighting module 5 uses LED lights, which are commercially available and mature devices in this field.

[0048] A conductive slip ring is fixedly installed on the fixed mounting base 1, and the auxiliary lighting module 5 is electrically connected to the external power line through the conductive slip ring.

[0049] In this embodiment, when the auxiliary lighting module 5 is in normal use, by setting the auxiliary lighting module 5 at the bottom of the rotating mounting base 2, the function of the ceiling fan is increased, so as to ensure lighting and fanning in a limited installation area.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
