[0003] In the prior art, the patent number is 201921805597.1, and the patent name is a metal fan wheel. Through different processing technology, the fan includes a hub, a plurality of fan blades arranged in a radial ring on the hub and a wheel disc for connecting the fan blades. The fan blades extend from the edge of the hub to the circumferential surface of the wheel disc, the hub includes a circular bottom plate and a circular wall vertically extending from the circular bottom plate, and the fan blades are formed from the circular wall of the hub to the wheel disc. The plurality of fan blades are integrally connected and formed as a whole with the hub and the wheel disc, the number of fan blades dispersed on the circumference of the hub is 15-4 pieces by one-shot injection molding of metal powder, the mass of the integrally connected fan blades is 1g-5g, the thickness of a single fan blade is greater than or equal to 0.1mm-0.2mm, and the outer diameter of the fan blade is 20mm-50mm. Although such a process can achieve a thin fan, the operation process is cumbersome, the shaft is not firmly wrapped, is easy to loosen, and the verticality is large, which leads to poor stability of the fan. UTILITARIAN CONTENT

[0004] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a fan blade structure with stable structure and ultra-thin structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] An ultra-thin fan blade structure includes a fan body, the fan body includes a main rotating disc, a fan blade and an outer wheel frame sleeved outside the main rotating disc, the fan blade is arranged in a circular array around the shaft of the main rotating disc on the outer wall of the main rotating disc, the outer wheel frame is sleeved outside the main rotating disc and on the fan blade, the end face of the connection end of the fan blade and the outer wheel frame is flush with the outer circular wall of the outer wheel frame, and the main rotating disc is provided with a shaft for welding with the output end of the motor.

[0007] The utility model is further provided with: the main rotating disc is provided with a disc-shaped protrusion, and a plurality of through holes are arranged on the disc-shaped protrusion.

[0008] The utility model further sets up: a plurality of through holes are arranged in ring shape on the protuberance of disc shape.

[0009] The utility model further sets up: the rotating disc, fan blade and outer wheel frame are integrally formed.

[0010] Compared with the prior art, the utility model has the beneficial effects that: the shaft is arranged on the main rotating disc, the output end head of the matched motor is welded through the shaft, the firmness of the whole fan blade is guaranteed, the fan blade cannot be loose, the whole rotation in the vertical state cannot have the problem of stability decline, and through the fixation of the outer wheel frame, the stability of the fan blade can be stabilized and cannot be deviated during rotation. BRIEF DESCRIPTION OF DRAWINGS

[0011] Fig. 1 It is structure schematic view of the utility model embodiment;

[0012] Fig. 2 It is structure schematic view of the utility model embodiment's shaft position; DETAILED DESCRIPTION

[0013] The utility model embodiments will be described below with reference to the accompanying drawings. Figs. 1-2 The technical solutions in the utility model embodiments are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0014] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0015] Through the integral molding of the main rotating disc 101 with the fan blades 301 and the outer wheel frame 201, the originally two two separated fan blades 301 are now connected together through the outer wheel frame 201, and the other side of the fan blades 301 is also integrally connected through the main rotating disc 101, so that the stability of the fan blades 301 is greatly improved, and a disc-shaped bulge 102 is formed at the center position of the main rotating disc 101, which improves the core strength of the core position of the main rotating disc 101, and with the help of the strength improvement of the core position, the shaft 401 is welded on the output end of the matching motor through laser welding, so that the connection strength is improved, and the firmness of the whole fan blade 301 is guaranteed, and the loosening of the fan blade 301 is prevented, so that the whole fan blade 301 can rotate stably in the vertical state, and the disc-shaped bulge 102 is provided with through holes 103 arranged at equal intervals and in a ring shape, so as to improve the air supply efficiency of the fan.

[0016] In this way, because the shaft 401 and the motor are welded with improved strength, the stability of the whole rotation is improved, and the whole firmness is improved, and at the same time, the thickness of the whole fan can be made thinner under the condition of ensuring the connection strength.

[0017] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and the skilled in the art can make usual changes and replacements within the technical scheme of the present application, which should be included in the protection scope of the present application.
