## Abstract

A disassemblable fan blade and a ceiling fan light. The disassemblable fan blade includes an outer fan blade, an inner fan blade, and a fixing member. The outer fan blade is detachably connected to the inner fan blade, and the fixing member is used to connect the outer fan blade and the inner fan blade. The outer fan blade and the inner fan blade are connected at an angle. Due to the outer fan blade being connected to the inner fan blade at an angle, the blowing area of the fan is increased. The fan blade includes two sections, that is the inner fan blade and the outer fan blade, which reduces the packaging volume for transportation and increases the utilization of packaging space, thus reducing transportation costs and making it less prone to damage.

## Claims

### Claim 1

A disassemblable fan blade,
wherein a complete disassemblable fan blade is divided into an inner fan blade and an outer fan blade to reduce package volume for transportation of the disassemblable fan blade;
wherein the outer fan blade is detachably connected to the inner fan blade by a fixing member;
wherein the fixing member comprises:
a front cover plate located below both the outer fan blade and the inner fan blade, configured to connect to lower contact surfaces of the outer fan blade and the inner fan blade, and
a rear cover plate located above both the outer fan blade and the inner fan blade, configured to connect to upper contact surfaces of the outer fan blade and the inner fan blade;
wherein the front cover plate and the rear cover plate are connected to the outer fan blade and the inner fan blade by a plurality of fastening members.

### Claim 2 (depends on 1)

The disassemblable fan blade according to claim 1, wherein the outer fan blade is configured to be connected to the inner fan blade at an angle to increase a blowing area of the disassemblable fan blade.

### Claim 3 (depends on 1)

The disassemblable fan blade according to claim 1, wherein a connecting end of the outer fan blade and a connecting end of the inner fan blade are respectively provided with a plurality of connecting holes for detachably connecting the outer fan blade and the inner fan blade.

### Claim 4 (depends on 3)

The disassemblable fan blade according to claim 3, wherein a plurality of ends of the front cover plate and a plurality of ends of the rear cover plate are respectively provided with a plurality of screw holes for connecting the outer fan blade and the inner fan blade,
wherein the plurality of screw holes corresponds to the plurality of connecting holes, and
the plurality of fastening members passes through the plurality of screw holes and the plurality of connecting holes to connect the outer fan blade and the inner fan blade.

### Claim 5 (depends on 4)

The disassemblable fan blade according to claim 4, wherein a limiting plate protruding upward from a top surface of the front cover plate is provided on each of two sides of the front cover plate to assist in connecting the inner fan blade and the outer fan blade.

### Claim 6 (depends on 5)

The disassemblable fan blade according to claim 5, wherein the plurality of screw holes protrudes upward from a top surface of the front cover plate, and a height of the protruding screw holes on the front cover plate is less than a height of the limiting plate, so as to facilitate the connection of the inner fan blade and the outer fan blade.

### Claim 7 (depends on 1)

The disassemblable fan blade according to claim 1, wherein a contact surface between the front cover plate and the outer fan blade is at a first angle with a contact surface between the front cover plate and the inner fan blade, and
the first angle is the same as a lower connecting angle between the outer fan blade and the inner fan blade.

### Claim 8 (depends on 7)

The disassemblable fan blade according to claim 7, wherein a contact surface between the rear cover plate and the outer fan blade is at a second angle with a contact surface between the rear cover plate and the inner fan blade, and
the second angle is the same as an upper connecting angle between the outer fan blade and the inner fan blade.

### Claim 9 (depends on 1)

A ceiling fan light, comprising the disassemblable fan blade according to claim 1.
