AI Technical Summary

Technical Problem

The air duct structure of the existing suction and blowing machine has poor sealing, complex manufacturing process, high cost, and users need to frequently plug and unplug accessories to switch functions, which affects the service life.

Method used

A hair dryer air duct structure is designed to unify the dust collection and blowing ports in the same air duct, and realize function switching through the air duct baffle, which reduces the manufacturing process requirements, improves the sealing performance, and controls the opening and closing of the air duct by a push button.

Benefits of technology

It solves the problems of poor sealing and complex manufacturing process, reduces manufacturing costs, optimizes user experience, extends joint life, and improves wind force and pressure performance.

Abstract

The utility model relates to the technical field of blowers, in particular to an air duct structure of a blower, which comprises a motor outer bin assembly, an external main air duct assembly, a hair bin assembly, a dust collection air duct assembly, a motor and a motor inner bin assembly. According to the scheme, the problem of air inlet source pollution is avoided, air inlet / outlet and air suction / exhaust switching holes are only formed in the end face of an existing similar structure, the manufacturing process needed by parts is reduced, the air duct sealing performance is improved, a dust suction opening and an air blowing opening of the whole machine are unified in the same air duct, the manufacturing cost is reduced, and the production efficiency is improved. The portable experience of a user and the wind power and wind pressure performance are optimized, the action that external equipment needs to be frequently inserted and pulled out when the suction and blowing functions are used is avoided, and the service life of the connector is greatly prolonged.
