Stick type vacuum cleaner

Abstract

A stick type vacuum cleaner is provided. The stick type vacuum cleaner includes a suction port assembly and a stick unit having a first end is engaged with a first side of the suction port assembly and a second end having a handgrip. The suction port assembly includes a casing part comprising a suction port through which air and dust is drawn from the object being cleaned, a suction force generating unit formed inside the casing part to generate a suction force, a dust separating unit to separate and accommodate dust from the drawn air and dust, and a power supply unit to supply power to the suction force generating unit. The suction force generating unit is disposed between the suction port and the dust separating unit so that the drawn air and dust is passed through the suction force generating unit before being introduced into the dust separating unit.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Korean Patent Application No. 2007-0086690, filed Aug. 28, 2007 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to a stick type vacuum cleaner, and more particularly, to a stick type vacuum cleaner, which has a power supply unit such as a battery of increased lifespan, and is capable of reducing noise level.[0004]2. Description of the Related Art[0005]Vacuum cleaners are among the most widely used home electronic appliances. Vacuum cleaners draw in air and dust from a surface being cleaned, using a suction force generated by a vacuum source.[0006]A canister vacuum cleaner includes a main body, a suction port assembly, and a connecting part. The main body includes a suction force generating unit and a dust separating unit to separate dust from air ...

AI Technical Summary

Benefits of technology

[0012]Exemplary embodiments of the present disclosure overcome the above disadvantages and other disadvantages not described above. Accordingly, it is an object of the present disclosure to provide a stick type vacuum cleaner which has a power supply unit of increased lifespan, and is capable of reducing noise level of the suction force generating unit.

Problems solved by technology

However, the dust separating unit can be damaged by the vacuum pressure being transmitted to the suction port.

When the suction force generating unit is arranged at a rear side of the cleaner like in the stick type vacuum cleaner, the suction force generating unit consumes a relatively large amount of power, causing decrease of life span of the power supply unit such as battery which supplies power to the suction force generating unit.

Furthermore, the impeller generates offensive noise during its fast rotation.
