One end of fan blade 3 is mounting portion 31, and mounting portion 31 includes upper mounting portion 32 and side mounting portion 33, is provided with joint groove 34 between upper mounting portion 32, the side mounting portion 33. Typically, the upper mounting portion 32 is substantially perpendicular to the side mounting portion 33. The air pushing portion 39 of the fan blade 3 is connected to the mounting portion 31, and the air pushing portion 39 rotates to push air to blow air. Since the thickness of the air pushers 39 is thin,

the connecting disc 2 is fixedly connected with the motor 11, for example, the connecting disc 2 is fixedly connected with the bottom end face of the motor 11 through a screw, and of course, the connecting disc 2 can also be fixedly connected with the top end face of the motor 11.

The connecting disc 2 is provided with a height limiting structure 22 and a clamping protrusion 24 protruding upwards.

The upper mounting portion 32 is provided with a mating structure 321.

Clamping protrusions 24 are inserted into the clamping grooves 34, and the matching structures 321 are connected with the height limiting structures 22 to limit the fan blades 3 from moving upwards relative to the connecting disc 2.

As a specific embodiment, the height limiting structure 22 is a limiting connection hole 221 provided on the connection disc 2, and the engagement structure 321 is a through hole provided on the upper mounting portion 32, through which a screw is screwed into the limiting connection hole 221, so that the blade 3 is limited from moving upward relative to the connection disc 2.

In a specific embodiment, the connecting disc 2 is fixedly provided with a limiting protrusion 222, and the limiting connection hole 221 is opened on the limiting protrusion 222.

In a specific embodiment, the connecting plate 2 is fixedly provided with a limiting protrusion 222, the height limiting structure 22 is an elastic protrusion 223 arranged on the side wall of the limiting protrusion 222, and the elastic protrusion 223 is inserted into the upper mounting part 32. The fan blade 3 can be assembled without screws, and is convenient.

When the motor 11 drives the fan blades 3 to rotate, the side walls of the clamping protrusions 24 abut against the side walls of the clamping grooves 34, and large centrifugal force generated by rotation of the fan blades 3 is offset.

When blade 3 is reversed (i.e., the posture of blade 3 with side mounting portion 33 positioned above upper mounting portion 32), side mounting portion 33 is more distinct than the forward direction of blade 3 (i.e., the posture of blade 3 with upper mounting portion 32 positioned above side mounting portion 33), and the probability of reverse assembly of blade 3 can be reduced.

As can be seen from the above, it is possible to overcome a large centrifugal force generated by the rotation of fan blades 3 while facilitating the assembly of fan blades 3.

In a specific embodiment, three or more blades 3 are provided, and the side mounting portions 33 of the blades 3 are abutted against each other.

In one specific embodiment, the engaging protrusion 24 has a circular ring shape in a plan view, and the engaging protrusion 24 has a ring sector shape. The connecting disc 2 is made of a metal disc with a bent edge, which forms a circular ring-shaped snap-in projection 24.
