Because this scheme has adopted foretell cleaning device brush body, it also has corresponding beneficial effect exactly, can refer to the preceding explanation specifically, need not repeated here.

The scheme is further described by combining the specific embodiment as follows:

the technical scheme of the invention is as follows:

the brush body includes: the roller brush comprises a shell, a connecting pipe, a wheel body, a roller brush component and a wiping component; wherein, the round brush subassembly includes: rolling and brushing; the wiping assembly comprises: the cleaning base body and the driving component for driving the cleaning base body to move are movably arranged in the containing cavity positioned at the bottom of the shell, the driving component is arranged in the shell, and the rolling brush and the cleaning base body are arranged front and back and face the ground.

Wherein, the bottom surface of the cleaning basal body, the bottom end of the rolling brush and the bottom end of the wheel body are all positioned on the same plane.

After the movable cleaning base body is additionally arranged at the rear position of the rolling brush, the ground cleaned by the rolling brush is wiped through the cleaning base body, so that the ground cleaning effect is improved.

The length of accomodating the chamber is greater than the length of clean base member, and the length of clean base member is greater than the length of round brush and is less than the length of accomodating the chamber, and when the clean base member moved about accomodating the chamber to the realization is cleaned ground.

Accomodate the chamber and include: first inside wall and second inside wall, clean base member includes: the first end portion faces the position of the first inner side wall, and the second end portion faces the position of the second portion side wall.

The length of accomodating the chamber is greater than the bilateral removal distance of clean base member + clean base member self length to two tip of avoiding clean base member move the in-process and take place the collision with two lateral walls of accomodating the chamber. As shown in fig. 3 and 4, when the first end portion 211.1 of the cleaning substrate 210 moves to the first inner sidewall 112 and reaches the maximum distance, a predetermined gap is formed between the first end portion 211.1 and the first inner sidewall 112. When the second end 211.2 of the cleaning substrate 210 moves towards the second inner sidewall 113 and reaches the maximum distance, a reserved gap is formed between the second end 211.2 and the second inner sidewall 113.

The cleaning base body comprises a moving plate and a cleaning part, and the cleaning part is detachably arranged on the bottom surface of the moving plate. The cleaning part can be a member having a floor wiping function such as a wiper, electrostatic paper, or the like.

The movable plate further comprises a plate body, four stand columns and positioning pieces, the four stand columns surround the outer side of the eccentric cavity and correspond to the four strip holes of the fixed plate in a one-to-one mode, and protruding portions are arranged at the tops of the stand columns to form a clamping effect.

The locating plate comprises a first locating plate and a second locating plate which are positioned at two sides of the eccentric cavity, and the positions of the first locating plate and the first locating plate correspond to each other.

The driving assembly comprises a driving motor, a bearing, a fixing plate and a swinging plate. The bearing is arranged in the mounting groove of the fixed plate, the swinging plate is arranged in the eccentric cavity of the moving plate, and the transmission shaft of the driving motor penetrates through the bearing and then is arranged in the eccentric hole of the swinging plate.

The fixing plate is fixed inside the housing such that the driving assembly is fixed inside the housing. The outside at the mounting groove of fixed plate still is equipped with four assembly strip holes, still is equipped with the constant head tank in the bottom of fixed plate.

When the fixed plate is assembled with the movable plate, the four stand columns are clamped in the four assembling holes, and the positioning sheet is arranged in the positioning groove. Because the length of the assembling strip hole is greater than that of the upright column, the moving plate can move left and right relative to the fixed plate.

Because the spacer is arranged in the constant head tank, and the top of spacer contacts with the inside of constant head tank, the movable plate passes through the spacer and forms the supporting effect to the fixed plate.

After a transmission shaft of the driving motor penetrates through the bearing and is connected with an eccentric hole of the swinging piece, the swinging piece rotates in the elliptical eccentric cavity in an eccentric state, and the cleaning base body is driven to move left and right during rotation so as to wipe the ground cleaned by the rolling brush through the wet cleaning part.

A cleaning device, comprising: the brush body is communicated with the machine body through a connecting pipe on the brush body so as to guide dust particles brought in by the rolling brush into the machine body.

The invention has the beneficial effects that:

1. after the movable cleaning base body is added at the rear position of the rolling brush, the ground cleaned by the rolling brush can be wiped through the cleaning base body, so that the ground cleaning effect is further improved;

2. because the length of the containing cavity is greater than the moving distance of the cleaning base body, the two end parts of the cleaning base body can be prevented from colliding with the two side walls of the containing cavity in the moving process;

3. because the positioning sheet is arranged in the positioning groove, and the top end of the positioning sheet is contacted with the inside of the positioning groove, the movable plate forms a supporting effect on the fixed plate through the positioning sheet, and further forms a supporting effect on the cleaning substrate;

4. the swinging piece eccentrically rotates in the eccentric cavity, and drives the cleaning base body to move left and right when rotating so as to wipe the ground cleaned by the rolling brush through the wet cleaning base body.
