Description

TECHNICAL FIELD

[0001] The present application relates to the field of floor washing machines, in particular to a cleaning chassis of a floor washing machine. BACKGROUND

[0002] In the prior art, such as a floor washing machine disclosed in Chinese patent ZL202010432180.6, the supporting roller can only rotate in the front-rear direction. Since the supporting roller does not have a lateral rotation function, when the user needs to turn, a relatively large force needs to be applied to the floor washing machine to realize the turning operation, which makes the turning of the floor washing machine relatively inconvenient and the user experience is poor.

[0003] Such as a floor washing machine roller brush and floor washing machine brush disclosed in Chinese patent ZL202210054105.X, since the outer surface of the arc-shaped part is flush with the outer surface of the brush housing, when the roller brush handle is inserted into the accommodation recess, the two need to be completely aligned to make the clamping groove and the protrusion, the lug and the groove mutually clamped. If the two are not aligned, the roller brush handle cannot be inserted into the accommodation recess, and the installation is relatively inconvenient. Moreover, the clamping groove and the protrusion, the lug and the groove have a small stress area, and the structural strength of the clamping structure is poor, which is easy to damage.

[0004] Such as a floor washing machine self-cleaning system and method disclosed in Chinese patent ZL202210779415.8, the scraper presses the roller brush on one side, but the motor only drives the roller brush to rotate in one direction, so that the scraper will press the bristle layer of the roller brush, that is, the bristles of the bristle layer are stacked together, which reduces the water absorption capacity of the bristle layer. Moreover, the pressed bristle layer can only act on the surface of the bristle layer during cleaning and drying, which makes it difficult to clean and dry the bristles inside the bristle layer, affecting the next cleaning work of the floor washing machine.

[0005] Such as a hand-held floor washing machine with sterilization device disclosed in Chinese patent ZL201921416869.9, the auxiliary rollers and the second auxiliary rollers each have two groups of structures for supporting the cleaning chassis when the floor washing machine is used. When the floor washing machine is used for cleaning, the auxiliary rollers will make a sound due to rotation, which affects the user's experience during cleaning operation. Moreover, the bristle layer on the surface of the roller brush will be worn after a period of use. If a new roller brush is not replaced in time, the rapid rotation of the bristle layer mounting part of the roller brush will cause scratches on the ground, which requires the user to pay attention to the wear of the bristle layer during use to prevent the bristle layer mounting part from scratching the ground. Therefore, the user needs to pay attention to the wear of the bristle layer in real time, which makes the use of the hand-held floor washing machine relatively inconvenient.

[0006] Therefore, it is necessary to design a new technical solution to solve the above problems. SUMMARY
