Description

A floor brush module for a cleaning machine and the cleaning machine

technical field

The utility model relates to the field of household cleaning equipment, in particular to a mobile cleaning device, in particular to a floor brush module for a cleaning machine and a cleaning machine.

Background technique

The cleaning machine is a relatively common household portable cleaning device. It first appeared in the form of a vacuum cleaner and can only be used in a dry environment. In order to meet the needs of more environments, especially in wet environments, such as floor washing machines, etc. Products are developed. Most of the existing floor washing machines adopt the front roller brush structure. By setting the roller brush on the front side of the casing that can rotate relative to the casing, the area covered by the rotation of the roller brush can be swept and cleaned, which is very convenient. , and while the roller brush itself is rolling, it can also play a role of boosting due to friction with the ground. However, the cleaning form of the roller brush also has certain disadvantages. The main force of the same type of model to achieve dust collection is the upstream negative pressure source (that is, the fan), which is limited by the horizontal rotation of the roller brush itself. For ground rotation The degree of contact is not enough, some stubborn stains cannot be cleaned well, and the water sprayed on the surface to be cleaned is sucked away by negative pressure after only one or two uses, the cleaning effect is relatively limited, and the roller brush is placed horizontally The method is extremely easy to entangle hair and pet hair, and it is very difficult to clean.

For this reason, the applicant has made some improvements to the traditional roller brush cleaning mode, and proposed another cleaning mode, which is disclosed in the Chinese invention application with the patent application number CN201911094051.4 (the public announcement number is CN112773255A). An "Integrated Structure for Surface Cleaning of Objects", the cleaning device is provided with a brush in the vacuum cylinder, and the brush can rotate in the axial direction inside the vacuum cylinder, that is, its rotation axis is different from the horizontal arrangement of the traditional roller brush, and is vertical extending. With such a brush arrangement, when working, the bristles can clean the ground to enhance the flow field in the central area of the fluid, cooperate with the cleaning liquid to reduce the residue of dirt in the central area, and avoid only a small amount of water cleaning ability in the rolling brush mode. When it is sucked away by negative pressure after two uses, it is more in line with the needs of heavy cleaning in wet environments.

The existing brush rotation mode is relatively simple, because the driving source adopts the cooperation of motor and gear, the brush can only sweep along a single rotation direction, so that the brush will generate a friction force in a single direction with the ground when it rotates, not only for the reciprocating pull of the ground brush The formation of resistance is not conducive to the cleaning of stains.
