The interior of the rotary cleaning mechanism is hollow and can hold cleaning liquid, the outside is provided with a cleaning liquid inlet, and the bottom is provided with a cleaning liquid outlet and cleaning materials.

The gear ratio of the internal gear (2) and the external gear (3) is 4:3.

Beneficial effects of the present invention: The dead corner cleaning device of the present invention adopts the Reuleaux triangle. With the aid of the equal width of the Reuleaux triangle, under the limiting action of the limiting support mechanism, the dead corner cleaning device can effectively clean the corners that are rounded. The debris and dust in the square dead corner area of the arc are cleaned, and the residual imprints in the corners are cleaned under the action of cleaning liquid and cleaning materials, so as to realize the cleaning of dead corners, and because the interior is hollow and can carry cleaning liquid, it saves the cleaning material replacement process.

Detailed ways

The structure and working principle of a dead angle cleaning device of the present invention will be further described below through examples and in conjunction with the accompanying drawings.

The present invention provides a dead angle cleaning device, as shown in FIG. 1, comprising a rotary cleaning mechanism 1, an internal gear 2, an external gear 3, a limit support mechanism 4, an eccentric shaft 5, a mop handle 6, a throttle device 7, a walking Wheel 8, drive motor 9, cleaning liquid inlet 10, cleaning liquid outlet 11, cleaning material 12, limit frame 13; the rotary cleaning mechanism 1 is installed on the eccentric shaft 5, and has a shape of a Reuleaux triangle, which rotates when cleaning corners The track is a square whose corners are arcs; the limit frame 13 is provided at the lower part of the limit support mechanism 4, and the limit frame 13 is installed with the traveling wheels 7, which are arranged on both sides of the limit support mechanism 4. A mop handle 6 is installed on the upper part of the limit support mechanism 4; the throttle device 7 is a connecting rod mechanism with a circular chassis, and is installed on the rotary cleaning mechanism 1; the internal gear 2 is internally meshed with the external gear 3, The gear ratio is 4:3; the eccentric shaft 6 can be divided into two parts, the upper part is connected with the drive motor 9 , and the lower part is connected with the internal gear 2 and the rotary cleaning mechanism 1 .

A cleaning liquid inlet 10 is provided on the outer side of the rotary cleaning mechanism 1 , and a cleaning liquid outlet 11 and a cleaning material 12 are provided on the bottom.

The cleaning material 12 includes cloth, sponge, and brush, and is driven by the rotating cleaning mechanism 1 to wipe the surface to be cleaned.

Before working, pour the cleaning liquid into the cleaning liquid inlet 10. When working, rotate the throttling device 7, the cleaning liquid outlet flows out of the cleaning liquid to soak the cleaning material 12 under the rotating cleaning mechanism 1, and drag the mop handle 6 to drive the overall dead corner cleaning device. The ground is cleaned, and the drive motor 8 drives the rotary cleaning mechanism to perform eccentric rotary motion. Under the action of the limit frame 13, the rotary cleaning mechanism 1 makes a square movement in the limit frame 13 with a trajectory with arcs. When moving to a dead corner such as a corner, the mop handle 6 remains motionless, and the rotary cleaning mechanism 1 rotates the garbage out of the corner, while the cleaning material 12 soaked in liquid cleans the imprints left in the corner.

FIG. 2 is a schematic structural diagram of a rotary cleaning mechanism, and FIG. 4 is a schematic diagram of a motion trajectory of the rotary cleaning mechanism. As shown in FIGS. 2 and 4 , the shape of the rotary cleaning mechanism 1 in the present invention is a Reuleaux triangle, which can rotate itself and revolve around the eccentric axis 5 under the action of the limiting frame 13 , and the rotation speed ratio of the rotation and revolution is 1 :3, it can make a square trajectory motion with the corners as arcs, so it has the effect of cleaning the garbage in dead corners.

FIG. 3 is a schematic diagram of the structure of the throttle device 7 , and FIG. 5 is a schematic diagram of the motion trajectory of the throttle device. As shown in FIG. 3 and FIG. 5 , the shape of the throttle device 7 of the present invention is a steering mechanism with a circular chassis, and the chassis rotates around the central axis with an included angle of 90 degrees therebetween. When there is no need to infiltrate the cleaning material, the throttling device 7 is rotated to cover the pores to prevent the liquid from infiltrating the cleaning material. When the cleaning material needs to be infiltrated, the throttling device 7 is rotated to a position that does not cover the pores, and the liquid flows out from the pores to infiltrate the cleaning material. Materials to clean up ground prints.

To sum up, a new type of dead corner cleaning device in this experiment uses the Reuleaux triangle as the cleaning unit, and uses its own rotation and revolution characteristics to effectively clean out the impurities in the corners of the wall. The material 12 is used to clean the corner prints to save manpower and water resources.
