DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is any conflict, the embodiments and features in the embodiments described below can be combined with each other in any manner.

[0037] Many different implementations or examples are provided below to implement the structure of the present invention.

[0038] See also Figures 1-12 , a ceiling fan with easy-to-assemble and disassemble blades according to an embodiment of the present invention comprises a suspension rod 1; a motor 2, mounted at the bottom end of the suspension rod 1; a turntable 3, connected and fixed to the motor 2, and driven to rotate by the motor 2. In this embodiment, the turntable 3 is fixed to the motor by screws, and a plurality of slots 31 are provided on the side wall of the turntable 3, and the number of the slots 31 is 3 or more, and the plurality of slots 31 are evenly arranged circumferentially on the side wall of the turntable 3. A card slot 32 is provided on the top of the turntable 3, and the card slot 32 is communicated with the slot 31; a motor protection shell 4 is fixed to the motor 2 or the turntable 3. In this embodiment, The motor protection shell 4 is fastened to the turntable 3 by a screw buckle, and a first elastic piece 5 is provided on the top of the motor protection shell 4, and the first elastic piece 5 corresponds to the position of the card slot 32; the blades 6 are 3 or more, and the roots of the blades 6 are provided with a second elastic piece 61, and the second elastic piece 61 is provided with a buckle 62; the root of the blade 6 is inserted into the slot 31, and the buckle 62 is buckled in the card slot 32 to fix the blade 6; by pressing the first elastic piece 5, the first elastic piece 5 can push the buckle 62 out of the card slot 32, so that the blade 6 can be pulled out of the slot 31.

[0039] When the blade needs to be installed, it is only necessary to insert the root of the blade 6 into the slot 31 so that the buckle 62 is buckled in the slot to fix the blade; when the blade 6 needs to be removed, press the first elastic piece 5, and the first elastic piece 5 can push the buckle 62 out of the slot 32, so that the blade 6 can be pulled out of the slot 31, abandoning the structure of fixing the blade by screws in the prior art. The embodiment of the utility model makes full use of the existing turntable and motor protection shell structure. Without adding additional spare parts, it is only necessary to set slots and slots on the turntable, corresponding buckles on the blades, and a first elastic piece on the motor protection shell (used as a button) to easily realize the disassembly and installation of the blades, which greatly facilitates user use and improves the user experience. The structure is simple and compact, and the implementation cost is low.

[0040] See Figure 4 and Figure 8 As shown, in some embodiments of the present invention, a protrusion 51 is provided at the end of the first elastic piece 5, and the protrusion 51 is used to push the undercut 62 out of the slot 32. The provision of the protrusion 51 improves the structural strength and service life of the first elastic piece 5. At the same time, it can reduce the deformation of the first elastic piece 5 to push the undercut 62 out of the slot 32, thereby improving the convenience and comfort of operation.

[0041] See Figure 4-Figure 6 、 Figures 9-11 As shown, in some embodiments of the present invention, the root of the blade 6 is provided with a first boss 63, and the cross-section of the blade root is a convex-shaped structure. The second elastic piece 61 is provided on the first boss 63. The slot 31 is provided with a second boss 33, and the second boss 33 is flanked by insertion grooves 34. The convex-shaped structure of the blade 6 is adapted to the second boss 33 and insertion grooves 34 in the slot 31 to limit the displacement of the blade 6. This structure allows the blade 6 to be restricted in multiple directions in the slot 31, preventing displacement of the blade 6 during high-speed rotation and ensuring the reliability of the connection of the blade 6 to the turntable 3.

[0042] See Figure 4 and Figure 10 As shown, in some embodiments of the present invention, a recessed groove 35 is provided on the second boss 33. The recessed groove 35 corresponds to the position of the second elastic piece 61. There is a gap between the recessed groove 35 and the second elastic piece 61 in the vertical direction to allow the second elastic piece 61 to be pressed downward and deformed. In other words, the recessed groove 35 acts as a relief. When the first elastic piece 5 is pressed, the first elastic piece 5 drives the undercut 62 downward, and the second elastic piece 61 follows suit and deforms downward. The provision of the recessed groove 35 provides sufficient space for the second elastic piece 61 to deform downward, thereby facilitating the removal of the undercut 62 from the slot 32.

[0043] See Figure 5 、 Figure 6 as well as Figure 11 As shown, in some embodiments of the present invention, an open slot 64 is provided at the end of the blade 6, and a limit plate 36 is provided in the slot 31. The limit plate 36 cooperates with the open slot 64 to limit the left and right shaking of the blade 6. When the blade 6 is inserted into the slot 31, the open slot 64 aligns with the limit plate 36, so that the limit plate 36 is snapped into the open slot 64. As a result, when the blade 6 rotates at high speed, its root is limited by the limit plate 36 and cannot shake left and right. Therefore, the connection of the blade 6 to the turntable 3 becomes more reliable, and the ceiling fan becomes safer.

[0044] See Figure 7 As shown, in some embodiments of the present invention, the first elastic sheet 5 is integrally formed on the motor protection shell 4, one end of the first elastic sheet 5 is connected to the motor protection shell 4, and the other end is disconnected from the motor protection shell 4 to form a through groove B; see Figure 6 As shown, the second elastic piece 61 is integrally formed on the blade 6, with one end of the second elastic piece 61 connected to the blade, and the other end is disconnected from the blade to form a through slot B. This method is to form the first elastic piece 5 and the second elastic piece 61 by respectively opening the through slot B on the original motor protection case 4 and the blade 6, making the structure simpler and without adding additional parts, which is conducive to reducing production costs.

[0045] See Figure 1 as well as Figure 4 As shown, in some embodiments of the present invention, a decorative cover 7 is further included, and the decorative cover 7 is arranged at the lower part of the turntable 3. In this embodiment, the decorative cover 7 is buckled on the turntable 3 through an inverted structure, and a panel 65 is provided on the blade 6. The panel 65 is connected to the decorative cover 7, so that after the blade 6 is plugged in and installed, the integrity of the entire ceiling fan is better and the aesthetics is improved.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
