Description

A scrubbing brush module and cleaning machine for cleaning machine

Technical Field

The utility model relates to a cleaning tool field of family specifically belongs to a scrubbing brush module and cleaning machine for cleaning machine.

Background

In the clean field of family, hand-held type negative pressure burnisher has followed the age of wired plug-in equipment, has gradually transitioned to the wireless device age of using wireless dust catcher, scrubber as the mainstream, has saved the restriction of pencil, makes the fuselage have highly liberalized operating space to greatly reduced the intensity of housework, very big promotion people's happiness of living. Because the negative pressure cleaning tool can be directly contacted with the ground when in work, the negative pressure cleaning tool plays a role in cleaning the ground, but the mobility of the machine body is limited due to the increase of the friction force with the ground, and the situation of pushing and pulling can occur during operation.

In order to solve the moving problem of equipment, the position of brush head assembly is improved by some manufacturers, and by means of the rotation of the brush head, the brush head can generate a driving force which is beneficial to moving between the brush head and the ground when the ground is cleaned, thereby playing a boosting effect, for example, the Chinese utility model with the patent number of CN201720866948.4 discloses a dust collector floor brush and a dust collector thereof, the interference between the brush hair and the surface to be cleaned causes the roller brush component and the surface to be cleaned to generate a larger friction force, and because of the existence of an acting force and a reaction force, the roller brush component can generate an obvious forward thrust in the rotating process, thereby achieving the labor-saving effect. Some manufacturers add an independent power-assisted system to the device, for example, chinese patent application No. CN202011074654.0 discloses a rear wheel reverse-driven dust collector floor brush, in which a rear wheel motor is fixedly mounted in a rear wheel mounting seat of a floor brush main body, a rotating shaft of the rear wheel motor is connected with a rear wheel, and an axis of the rear wheel is parallel to an axis of a front wheel. When the floor brush of the dust collector is pulled backwards, the rear wheel motor on the floor brush drives the rear wheel to rotate backwards so as to realize the boosting effect.

Although the cleaning device can realize the assistance, on one hand, an independent driving mechanism is arranged, so that the additional production cost is increased, on the other hand, for the use mode similar to the one-push one-retraction type when a mop is used, the independently arranged driving mechanism cannot play the role of assistance in the first time, the labor is possibly increased, and the machine body is suddenly pulled backwards when the mop is pushed forwards to clean, so that the motor is easily damaged due to forced blocking and reverse rotation.

There is therefore also a need for improvements to existing boost modes.
