[0031] The utility model embodiment provides a fan blade assembly, referring to Figure 1-5 The fan blade assembly includes a rotating shaft 1, a fan blade body 2 and a clamping member 3; a clamping position 11 and a mounting position 12 are sequentially provided at the first end of the rotating shaft 1, and the fan blade body 2 is mounted on the mounting position 12 of the rotating shaft 1; the clamping member 3 is arranged on the fan blade body 2 and clamped with the clamping position 11, so that the fan blade body 2 and the rotating shaft 1 can be detachably connected.

[0032] As an example, the fan blade assembly includes a rotating shaft 1, a fan blade body 2 and a clamping member 3. The second end of the rotating shaft 1 is used to be connected to a driving source. The fan blade body 2 is installed on the first end of the rotating shaft 1. The driving source drives the fan blade body 2 to rotate through the rotating shaft 1. During installation, a clamping position 11 and a mounting position 12 are sequentially provided at the first end of the rotating shaft 1. The clamping member 3 is arranged on the fan blade body 2. When the fan blade body 2 is installed on the mounting position 12 of the rotating shaft 1, the clamping member 3 can be clamped with the clamping position 11 to realize the detachable connection between the fan blade body 2 and the rotating shaft 1. Among them, the mounting position 12 is specifically formed by cutting off a part of the outer circumference from the first end of the rotating shaft 1 or a position close to the first end of the rotating shaft 1 along the axial direction of the rotating shaft 1. For example, the mounting position 12 is a flat position. The fan blade body 2 is installed on the mounting position 12 of the rotating shaft 1. The two are specifically matched in a flat position to prevent the fan blade body 2 from moving around. When the fan blade body 2 needs to be removed, it is only necessary to use a certain force to pull the fan blade body 2 in the opposite direction of the installation direction of the fan blade body 2 so that the clamping piece 3 and the clamping position 11 are no longer clamped, so that the fan blade body 2 can be separated from the rotating shaft 1, and then the fan blade body 2 can be cleaned and flushed separately; the fan blade assembly structure and process are simple in this way, and disassembly and assembly do not require special tools and additional covers, and can be quickly disassembled and installed, thereby improving convenience of use.

[0034] As an example, the first structure of the fan blade assembly is introduced: the clamping member 3 includes a fixing seat 31 and a buckle 32; the fixing seat 31 is fixed on the fan blade body 2, and the buckle 32 extends from one end of the fixing seat 31 in a direction perpendicular to the fixing seat 31; when the fan blade body 2 is completely installed on the installation position 12 of the rotating shaft 1, the buckle 32 is engaged with the engaging position 11 to lock the fan blade body 2 on the rotating shaft 1 to prevent the fan blade body 2 from falling out. When the fan blade body 2 needs to be removed, it is only necessary to use a certain force to pull the fan blade body 2 in the opposite direction of the installation direction of the fan blade body 2 so that the buckle 32 is no longer engaged with the engaging position 11, so that the fan blade body 2 can be separated from the rotating shaft 1, and then the fan blade body 2 can be cleaned and flushed separately; the fan blade assembly structure and process are simple in this way, and no special tools and additional covers are required for disassembly and assembly, so it can be quickly disassembled and installed, which improves the convenience of use.

[0035] In one embodiment, referring to Figure 3 The fixing seat 31 and the fan blade body 2 are integrally formed.

[0036] As an example, the fixing seat 31 is integrally formed with the fan blade body 2, so that the clamping member 3 and the fan blade body 2 are an integrated structure, which can reduce the number of parts, and the fan blade body 2 can be directly pushed and pulled during installation and disassembly, while also improving the connection reliability of the clamping member 3.

[0037] In one embodiment, referring to Figure 1 and Figure 4 The buckle 32 is made of plastic or metal.

[0038] As an example, the material of the buckle 32 is a plastic material or a metal material, which can produce deformation, so that the buckle 32 is engaged with the engaging position 11, so as to lock the fan blade body 2 on the rotating shaft 1 and prevent the fan blade body 2 from falling out. When the material of the buckle 32 is a plastic material, the fan blade assembly structure is simple, the assembly process is simple and easy to operate, the cost is low, it can be used as a consumable, and it is easy to replace. When the material of the buckle 32 is a metal material, the metal material is not easy to be damaged, and can meet the requirements of hundreds of times of disassembly of the product, thereby improving the durability of the product. The buckle 32 can also be made of other materials with specific deformation capabilities.

When the fan blade body 2 needs to be removed, it is only necessary to use a certain force to pull the fan blade body 2 in the opposite direction of the installation direction of the fan blade body 2 to overcome the pressure of the metal spring 33, so that the second end of the metal spring 33 is deformed and no longer engaged with the engaging position 11, so that the fan blade body 2 can be separated from the rotating shaft 1, and then the fan blade body 2 can be cleaned and flushed separately; the fan blade assembly structure and process are simple in this way, and no special tools and additional covers are required for disassembly and assembly, so it can be quickly disassembled and installed, which improves the convenience of use. Among them, at least two metal springs 33 can be arranged evenly spaced along the circumferential direction of the rotating shaft 1, so that the connection between the second end of the metal spring 33 and the engaging position 11, i.e., the first card slot, is more balanced and stable.
