Surface cleaning equipment

Abstract

The invention relates to surface cleaning equipment. The surface cleaning equipment comprises a body portion and a cleaning head located below the body portion. The cleaning head comprises a shell and a brush assembly installed at the bottom of the shell. The brush assembly at least comprises four scrubbing brushes, namely, the first scrubbing brush, the second scrubbing brush, the third scrubbing brush and the fourth scrubbing brush. The first scrubbing brush and the second scrubbing brush are horizontally arranged side by side, the third scrubbing brush and the fourth scrubbing brush are horizontally arranged side by side, the first scrubbing brush is located on the front side of the fourth scrubbing brush, the second scrubbing brush is located on the front side of the third scrubbing brush, and the first scrubbing brush, the second scrubbing brush, the third scrubbing brush and the fourth scrubbing brush can move in a horizontal plane. The four scrubbing brushes on the cleaning head can simulate a human hand which can vertically and horizontally clean floors in a reciprocating mode in the working process, in addition, the vertical or horizontal movement directions between every adjacent scrubbing brushes are opposite, and therefore dynamic balancing of the brush assembly in the working process can be achieved. Thus, vibration of the surface cleaning equipment provided with the cleaning head is lower than that of common surface cleaning equipment in the working process.

Description

technical field

[0001] The invention relates to a surface cleaning device for floor cleaning. Background technique

[0002] In cleaning devices, a cleaning head with a brush assembly is the most common component. A common brush assembly includes a brush body, bristles arranged on the brush body, and a motor that drives the brush body to move. The brush body can be a rotating brush body or a fixed brush body, such as the following structures:

[0003] The first one, referring to the Chinese patent whose patent application number is 200710057360.5, discloses a double roller brush structure of the brush head of a vacuum cleaner, in which there is a pair of roller brushes rotating around the horizontal axis line, two The rotating direction of the roller brush on the same brush head is different, and the two-way rotation of the roller brush can clean up the sundries lying on the floor more thoroughly during cleaning. The pair of rolling brush bodies is in "line contact" with t...

Embodiment Construction

[0024] Below in conjunction with the embodiment shown in the accompanying drawings, the present invention is described in detail as follows:

[0025] like figure 1 In the shown surface cleaning device, the upper part is a main body 1 , and the lower part of the main body 1 is a cleaning head 2 . The main body part 1 is provided with components such as a vacuum source and a dust collection unit. The cleaning head 2 is used to move on the ground to be cleaned, thereby sucking up the dirt on the ground and sending it into the main body 1 for air-ash separation. The cleaning head 2 has a housing 3, the lower bottom of the housing 3 has a dust suction port 4, and the lower bottom of the housing 3 is also equipped with a brush assembly 5 near the dust suction port 4, and this brush assembly 5 is used for bonding the The stubborn dirt on the ground to be cleaned is swept up, and then sucked into the main body 1 by the dust suction port 4 for air-ash separation.
