AI Technical Summary

Technical Problem

The air volume of existing micro-blowers is small. If the number of blades is increased, the air inlet space will become smaller. If the thickness of the blade is reduced, it will easily be damaged. It is difficult to make reasonable improvements in the number and thickness of the blades to increase the air volume.

Method used

By increasing the number of fan blades and making a larger mold angle, the thickness of one end of the fan blade is reduced to the air outlet, and it is thin at the top and thick at the bottom, increasing the air inlet space of the upper thin part, while ensuring the connection strength of the lower thick part, avoiding the fan blade being easily damaged.

Benefits of technology

The air volume of the micro blower is increased, and the air inlet space is increased by reasonably improving the number and thickness of the fan blades, while ensuring the strength and durability of the fan blades.

Abstract

The utility model relates to the technical field of miniature blower fan blades, in particular to a large-air-volume miniature blower fan blade which comprises a base, a sealing cover is connected to the upper end of the base in a clamped mode, an air opening is formed in the middle of the sealing cover, a fan base is rotationally connected between the base and the sealing cover, and a plurality of sets of blades are fixedly connected to the side wall of the fan base in an inclined mode. The thickness of the ends, close to the air opening, of the blades is smaller than that of the ends, away from the air opening, of the blades, and a driving assembly is fixedly connected into the base and matched with the fan base in a driving mode. The fan blades are driven to rotate between the base and the sealing cover through the driving assembly, the number of the fan blades is increased, the mold shifting angle is increased, the thickness of the ends, close to the air opening, of the fan blades is reduced, the fan blades are in the shape with the thin upper portions and the thick lower portions, the air inlet space between the thin-up fan blades is increased, and the thick-down fan blades guarantee the connection strength of the fan blades and prevent the fan blades from being damaged easily; the number and the thickness of fan blades are reasonably improved, and the air volume of the miniature air blower is increased.
