Problems solved by technology

[0009] The past vertical vacuum cleaner roller brush connection structure is composed of left and right connecting parts 26, 27 connected to the left and right end covers 28, 29 of the suction nozzle chassis 8, rollers 24 and bristles 25 spirally arranged on the rollers. Since the bosses at the ends of the left and right connecting parts 26 and 27 are larger than the end cap protection rings 31 of the mounting parts 30 of the left and right end caps 28 and 29, foreign objects such as dust and hair easily enter the mounting parts of the end caps and cause rolling brushes. Difficulty or even inability to turn
Disable the roller brush

Abstract

The present invention discloses one kind of rolling brush connecting structure for vertical vacuum cleaner as one hand supported vacuum cleaner. The rolling brush connecting structure includes rotatable right and left connecting parts connected to the right and left end cap of the suction nozzle separately, roller, and bristles set spirally on the roller. It features the end cap protecting rings set in the right and left end cap installing units to hold the end bosses and the end bosses in the right and left connecting units to form inclined slot. The present invention has low possibility of dust and other foreign matters to enter to the end cap installing units so as to ensure the normal rotation and long service life of the rolling brush.

Description

Technical field [0001] The present invention relates to the structure of a vacuum cleaner supported by hand, specifically a dust-proof roller brush connection structure of an upright vacuum cleaner. Background technique [0002] A vacuum cleaner is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the structure and appearance of vacuum cleaners, they are usually divided into upright vacuum cleaners, horizontal vacuum cleaners, and portable vacuum cleaners. [0004] The structure of a vacuum cleaner generally includes a vacuum cleaner motor that generates suction power by introducing electric current, a nozzle, a hose, and a filter bag that form an air path system, and a dust collection part that collects inhaled matter. [0005] like Figure 1-4 As shown, the upright vacuum cleaner includes a handle 2 on the upper part of the body 1 that is convenient for the user to push and pull, ...
