Technical Field

Embodiments of the present invention relate to a suction port body of an electric vacuum cleaner having a plurality of suction ports opened in front and rear of a main body, and an electric vacuum cleaner including the suction port body.

Background

Conventionally, as a floor brush serving as a suction port body used in connection with an extension pipe of an electric cleaner or a cleaner main body, there is a floor brush having a plurality of suction ports in the front and rear.

However, since the plurality of suction ports do not have a difference in vacuum degree, the types of dust that can be sucked by the floor brush using the plurality of suction ports are limited, and it cannot be said that the dust removing performance is sufficiently good.

In particular, in order to suck large dust, it is necessary to sufficiently separate the ribs that partition the front portion of the front suction port from the surface to be cleaned, and as a result, the degree of vacuum in the front suction port is reduced, and the ability to remove fine dust is also reduced.

Disclosure of Invention

The present invention addresses the problem of providing an electric vacuum cleaner having improved dust removal performance, and an electric vacuum cleaner provided with the same.
