Benefits of technology

[0013]The present invention have been conceived to solve such problems in the art and an aspect of the present invention is to provide a cleaning nozzle assembly which can switch inlets of a cleaning nozzle receiving air and foreign substances to selectively provide dust suction over a wider area and intensive dust suction, and to allow adjustment of suction force, thereby sufficiently suctioning only air and foreign substances while preventing damage to a surface to be cleaned.
[0014]Another aspect of the present invention is to provide a cleaning nozzle assembly which includes a bearing provided to whe

Problems solved by technology

Here, friction between the body and the wheels, both of which are injection molded articles, causes noise.
In addition, a typical vacuum cleaner has a problem in that when cleaning is performed using a rotary brush type suction nozzle for cleaning ca

Abstract

A cleaning nozzle assembly of a vacuum cleaner. The cleaning nozzle assembly includes: a lower case having a main inlet and a lower sub-inlet to guide foreign substances and air to be introduced into the lower case, wherein the lower case is open at an upper side thereof and includes a partition wall isolating the main inlet from the lower sub-inlet and having a connection hole; an upper case coupled to the lower case to cover the open upper side of the lower case; and an inflow setting unit setting inflow of foreign substances and air into the lower case through the lower sub-inlet and an upper sub-inlet by opening/closing the connection hole. The cleaning nozzle assembly can switch inlets of a cleaning nozzle receiving air and foreign substances, thereby selectively providing dust suction over a wider area and intensive dust suction, can prevent noise from being generated by wheels of the cleaning nozzle, and allows the cleaning nozzle to remain horizontal with respect to a floor when a transfer pipe provided to the cleaning nozzle for changing a cleaning location during cleaning is lifted up.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to a cleaning nozzle assembly. More particularly, the present invention relates to a cleaning nozzle assembly which can switch inlets of a cleaning nozzle receiving air and foreign substances, thereby selectively providing dust suction over a wider area and intensive dust suction, prevent a noise generated by wheels of the cleaning nozzle, and allow the cleaning nozzle to remain horizontal with respect to a floor when a transfer pipe provided to the cleaning nozzle for changing a cleaning location during cleaning is lifted up.[0003]2. Description of the Related Art[0004]A typical vacuum cleaner has a structure wherein a motor for generating vacuum and an envelope type filter are disposed within a main body of the cleaner to allow sludge to be introduced into the main body of the cleaner through vacuum force generated by activation of the motor and to be filtered out through the filter, such that filth having been ...
