Referring to fig. 4 and 7, the bracket 50 includes a first portion 51 connected to the motor cover 40, the first portion 51 being constructed in a fork shape, and a second portion 52 connected to the body 10, the second portion 52 being constructed in a shaft shape, the first portion 51 being pivotally connected to the body of the floor brush assembly along a first axis shown as an X-X axis, wherein the fork-shaped first portion 51 is mounted to both sides of the motor cover 40 in an axial direction of the motor cover 40, and the second portion 52 being pivotally connected to the body 10 along a second axis shown as a Y-Y axis, i.e., a center line of the shaft shape of the second portion coincides with the Y-Y axis. The stand 50 is capable of switching between an upright position and a use position of the cleaner with respect to the brush assembly 30, the cleaner being in an upright position, the stand 50 limiting rotation of the motor cover 40 with respect to the brush assembly 30 in a first rotational direction, which may be clockwise in fig. 4 or 5, the essential direction being the direction in which the cleaner rotates from the upright position to the main body during a change in use; the cleaner is in use and the stand 50 is rotated relative to the brush assembly 30 and releases the restriction of rotation of the motor cover 40 relative to the brush assembly 30 in the first rotational direction. When the cleaner is not in use, the body 10 is arranged to be substantially upright relative to the floor surface, i.e. the upright position of the cleaner, and may also be considered to be the storage position of the cleaner, in which case the O-O axis is substantially perpendicular to the floor surface.

Accordingly, the number of the reed 311 is also set to 2.

As shown in fig. 7, the motor cover 40 is provided with a first abutting portion 41, the bracket 50 is provided with a bracket abutting portion 521, the bracket abutting portion 521 is located at the shaft-like second portion 52, and in the standing state, the bracket abutting portion 521 is held against the first abutting portion 41, so that the bracket 52 restricts the rearward rotation of the motor cover 41, i.e., the rotation in the clockwise direction in fig. 4 and 5. In use of the cleaner, only a rearward force is required to the handle, the protrusion 313 of the reed 311 is disengaged from the recess 511 of the first portion 51 of the bracket 50 and the bracket abutment 521 is disengaged from the first abutment 41, so that both the bracket 50 and the motor cover 40 can be rotated about the first axis shown in the X-X axis.

In addition, in the upright state, not only the rotation of the motor cover 41 in the clockwise direction but also the rotation of the motor cover 41 in the counterclockwise direction is restricted. Specifically, the floor brush assembly 30 includes a roller brush 35 and a first roller 33 that are disposed at intervals, the roller brush 35 and the first roller 33 are supported on a floor brush body 31 and a wheel frame 32 of a floor brush assembly main body, respectively, a motor cover 40 is pivotally mounted on the floor brush body 31, a second abutting portion 42 is provided on the motor cover 40, a wheel frame abutting portion 322 is provided on the wheel frame, and in an upright state, the second abutting portion 42 is held in abutment with the wheel frame abutting portion 322, thereby restricting rotation of the motor cover 41 in the counterclockwise direction. In addition, the ground brush body 31 is movably connected with the wheel frame 32, the second roller 34 is supported on the ground brush body 31, the roller brush 35, the first roller 33 and the second roller 34 are sequentially arranged along the cleaning direction of the dust collector, and in an upright state, the roller brush 35 is kept in the air relative to the plane P-P where the first roller 33 and the second roller 34 are positioned by the second abutting part 42 and the wheel frame abutting part 322, so that the damage of the roller brush to the ground during storage is reduced, and the abrasion of the roller brush is reduced.

Referring to fig. 9 to 12, when the concave portion 511 of the bracket 50 is separated from the convex portion 313 of the reed 311, the rearward rotation of the bracket 50 is not restricted but the rearward rotation of the motor cover 40 is restricted by the ground brush assembly 30. Specifically, the ground brush 31 is provided with the ground brush abutting portion 312, and in the use state, the second abutting portion 42 is separated from the wheel carrier abutting portion 322 and abuts against the ground brush abutting portion 312, whereby the rearward rotation of the motor cover 40 in the clockwise direction is restricted by the ground brush abutting portion 313, and therefore, the motor cover 40 can rotate relative to the ground brush 31 only within the range in which the second abutting portion 42 abuts against the ground brush abutting portion 313 and the wheel carrier abutting portion 322, respectively.

In addition, in the use state, the wheel frame 32 and the ground brush body 31 are movably connected, so that the wheel frame 32 and the ground brush body 31 can relatively move, the wheel frame 32 is released due to the fact that the limitation of the backward rotation of the motor cover 40 is released, the rolling brush 35 descends under the gravity action of the ground brush assembly 30, the wheel frame 32 ascends, and the wheel frame 32 can drive the motor cover 40 to rotate along the X-X axis. The roller brush 35, the first roller 33 and the second roller 34 are grounded, so that cleaning and dust collection can be performed. In this way, the cleaner is switched between the upright state and the use state, the relative positions of the wheel frame 32 and the ground brush body 31 are changed, and the roller brush 35 is suspended or landed relative to the plane P-P where the first roller 33 and the second roller 34 lie.

Preferably, the ground brush 31 is pivotally connected to the wheel carriage 32 along a third axis parallel to the first axis, which may be the axis shown by the X1-X1 axis in fig. 14, so that pivoting between the ground brush 31 and the wheel carriage 32 about the third axis enables the roller brush 35 to be raised and lowered, and in use, the wheel carriage 32 rotates the motor cover 40 via the second abutment 42.

The motor cover 40 is further provided with a third abutting portion 43, and the third abutting portion 43 is located at the rear side of the second abutting portion 42 in the first rotation direction, i.e., in the clockwise direction, and the wheel frame 32 is provided with a wheel frame rear abutting portion 323, and the third abutting portion 43 abuts against the wheel frame rear abutting portion 323 to restrict rotation of the motor cover 40 in the first rotation direction.
