Air intake duct structure of a vacuum cleaner

Abstract

The invention discloses the structure of the air inlet duct of the vacuum cleaner. The air inlet duct includes a groove formed on one side wall of the dust cup, and a cover plate covering the groove, and the groove and the cover plate cooperate to form two ends. The air intake duct is open; the dust air enters the air intake duct through the opening at the bottom of the dust cup, and then enters the dust cup through the opening above the air intake duct to separate the dust and air. The air inlet duct is arranged outside the dust cup and does not occupy the space of the dust cup itself, which simplifies the structure of the dust cup and increases the ash storage space. Moreover, the groove can be integrally injection molded when forming the dust cup, the molding process is simple, the production is convenient, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of structural design of a vacuum cleaner, and in particular relates to a structure of an air inlet duct of a vacuum cleaner. Background technique [0002] As the name suggests, the handheld vacuum cleaner is a vacuum cleaner that can be used for dust removal. The vacuum cleaner is small in size and very convenient to carry and use. Space, mainly used for cleaning inside the car, also has a good effect on keyboards, electrical appliances, etc. The usual application fields are carpets, cleaning inside the car, electrical appliances, home furnishing, etc. [0003] The handheld vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate strong suction and pressure at a speed of 500 cycles per second. Sufficiently replenish the air in the fan, resulting in an instant va...

AI Technical Summary

Problems solved by technology

[0004] The air inlet duct of the traditional hand-held dust cup system exists in the dust cup as a whole. Compared with ordinary household vacuum cleaners, the dust cup of the hand-held vacuum cleaner is smaller in size, and the space for storing dust is limited. By integrating the air inlet duct as a whole Set in the dust cup, this structural form greatly affects the ash holding capacity of the dust cup, and in the manufacturing process, the production process is more complicated, and the molding is inconvenient, which also has a great impact on the mold capacity of the dust cup
