However, there is generally no opening on the center plate. When the impeller structure of the blower rotates, the motor at the rear of the blower will heat up more seriously, and the wind entering from the front of the blower will directly go out from the air duct provided on the blower casing. The motor is used for cooling, so the cooling performance of the blower is not good

Embodiment Construction
[0010] Such as figure 1 As shown, an impeller structure of a blower includes a central disk 1, and as a preference of the present invention, an annular groove 7 is stamped and formed on the edge of the central disk 1. The central disk 1 is stamped with large blades 2 and large openings 3 corresponding to the large blades 2. The large blades 2 are evenly distributed along the circumference of the central disk 1, and the height of the large blades 2 extends from the inside of the central disk 1 to the The direction of the outside gradually decreases. The end of the large blade 2 near the edge of the central disk 1 is bent into an arc shape. The central disk 1 is stamped with a small blade 4 between two adjacent large blades 2 and corresponding to the small blade 4. The small opening 5, the large opening 3 and the small opening 5 are square, the large blade 2 and the small blade 4 are close to the edge of the central disk 1, and the middle part of the central disk 1 is provided w...

The invention discloses an impeller structure of an air blower. The impeller structure comprises a central disc, wherein big blades and big openings corresponding to the big blades are formed on the central disc by stamping; one end of each big blade, close to the edge of the central disc is bent in an arc shape; small blades and small openings corresponding to the small blades are formed between the adjacent two big blades by stamping; a bow-shaped through hole matched with an output shaft of a motor of the air blower is formed in the middle of the central disc. According to the impeller structure, the big blades and the small blades are all formed by stamping, difficultly fall from the central disc and are very reliable to connect, very simple to manufacture and high in production efficiency; and the big openings and the small openings are formed in the central disc, and air entering the front part of the air blower can be blown to the motor of the air blower from the big openings and the small openings, so that the motor is cooled, the temperature of the motor can be reduced, the heat radiation of the motor is facilitated, and the service life of the motor can be effectively prolonged.
Description
technical field [0001] The invention relates to a blower, in particular to an impeller structure of the blower. Background technique [0002] At present, the impeller on the blower generally includes a central disk and blades fixed on the central disk, and the blades are evenly distributed along the circumference of the central disk. However, there is generally no opening on the center plate. When the impeller structure of the blower rotates, the motor at the rear of the blower will heat up more seriously, and the wind entering from the front of the blower will directly go out from the air duct provided on the blower casing. The motor is used for cooling, so the cooling performance of the blower is not good. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides an impeller that allows the wind energy that enters from the front of the blower to cool the motor of the blower. [0004] The technical solution adopted...
