Description

Technical Field

[0001] The utility model relates to the field of sweeping robots, in particular to a sweeping robot used for floor cleaning. Background Art

[0002] A sweeping robot is a smart home appliance that can replace manual cleaning of dust and foreign objects on the ground, and can provide great convenience for people's lives. Usually, a sweeping robot is equipped with a motor for driving the driving wheel and a motor for driving the cleaning brush, and most of them are disc-shaped.

[0003] There is a Chinese patent with the patent number CN216293918U, which discloses a sweeping robot, including a main body, a detachable air outlet housing is installed on the surface of the main body, and the air outlet housing is detachably connected to a wafer stage, and the wafer stage is suitable for carrying a wafer, and the wafer stage is suitable for absorbing volatile substances. In this scheme, the volatile substances are absorbed by the wafer stage, and during the movement of the robot, the volatile substances are diffused into the room, thereby increasing the freshness of the room air. However, the overall frame of the robot is a circular structure. When the robot moves to the wall and the corner position, it is difficult to clean the dust at the intersection of the wall and the bottom plate, so there are still deficiencies in the cleaning effect; in view of this, we propose a sweeping robot for floor cleaning that can improve the cleaning effect and facilitate the cleaning of the cleaning plate. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a sweeping robot for floor cleaning which can improve the sweeping effect and facilitate the cleaning of the sweeping plate.

[0011] Preferably, a cover is mounted on the top of the shell, and the cover is located above a dust box installed inside the shell. The dust in the dust box can be taken out by opening the cover, which effectively improves the convenience of cleaning the dust.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] 1. During the movement of the robot, the guide wheel can prevent the outer shell from colliding with the wall, and the robot can move close to the wall. At this time, the brush installed on the cleaning board can clean the dust at the intersection of the wall and the floor, achieving the purpose of cleaning without dead ends, and effectively improving the cleaning effect of the robot.

[0014] 2. The cleaning plate can be fixed to the outer shell by screws passed through the connecting plate. When the brush on the cleaning plate needs to be cleaned, the cleaning plate can be removed from the outer shell for cleaning. During the cleaning process, water can be prevented from entering the inner shell, which effectively improves the convenience of cleaning the cleaning plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the utility model proposes a floor sweeping robot for floor cleaning, including a housing 1, two driving wheels 7 are rotatably mounted on the bottom of the housing 1, a universal wheel 5 is provided on one side of the driving wheel 7, and the universal wheel 5 is rotatably mounted in a groove at the bottom of the housing 1, and a brush roller 8 is rotatably mounted on the bottom of the housing 1, and the part of the brush roller 8 embedded in the housing 1 is located on the opening side of the dust box installed inside the housing 1, and the dust and foreign matter can be swept into the dust box when the brush roller 8 rotates. The four outer walls of the housing 1 are fixed with cleaning plates 2 by screws, and a plurality of brush plates 21 are welded to the bottom of each cleaning plate 2, and a plurality of bristles 22 are bonded to the bottom of each brush plate 21. When the housing 1 is placed on the floor, the bottom end of the bristles 22 fits the floor, ensuring that the bristles 22 can clean the dust on the floor when the robot moves. Moreover, side openings are cut at the four corners of the outer wall of the housing 1, and a guide wheel 3 is rotatably mounted in each side opening, and a portion of each guide wheel 3 extends to the outside of the side opening;

[0024] Furthermore, two connecting plates 24 are welded on the top of each cleaning plate 2, and each connecting plate 24 is fixed to the outer wall of the outer shell 1 by screws. Two cylindrical positioning blocks 23 are cast on one end of each cleaning plate 2 close to the outer shell 1, and two circular grooves are chiseled on the four outer walls of the outer shell 1. The above-mentioned positioning blocks 23 are embedded in the corresponding circular grooves and are snap-connected therewith.

[0025] The working principle of a floor sweeping robot for floor cleaning based on the first embodiment is: firstly, the robot is placed on the floor, the shaft of the driving wheel 7 is driven to rotate by the driving motor, and then the rotating driving wheel 7 provides power for the robot, and the universal wheel 5 installed at the bottom of the shell 1 can play a steering role. During the movement of the robot, the brush roller 8 is driven to rotate by the rotating motor installed inside the shell 1, and foreign objects and dust on the floor can be swept into the dust box. When the robot moves to the wall 9, the guide wheel 3 can prevent the shell 1 from directly colliding with the wall 9, and the guide wheel 3 can also assist the robot to move on one side of the wall 9. At this time, the bristles 22 installed at the bottom of the cleaning plate 2 can clean the dust and foreign objects at the intersection of the wall 9 and the floor. As the robot moves, the dust at this place can be transferred to a position away from the wall 9, and then the brush roller 8 can clean it, which can solve the problem that the traditional robot is difficult to clean the dust near the wall 9, and realize the cleaning without dead angles, and effectively improve the cleaning effect of the robot. When the cleaning plate 2 and the bristles 22 need to be cleaned, the screws at the connecting plate 24 can be removed, and then the cleaning plate 2 can be removed from the outer shell 1, and the bristles 22 can be directly washed with water. During the cleaning process, water will not enter the inner part of the outer shell 1, which effectively improves the convenience of cleaning the cleaning plate 2.

[0026] Embodiment 2

[0027] like Figure 1-5 As shown, the utility model proposes a sweeping robot for floor cleaning.

[0028] Reference Figure 4 Two triangular brushes 6 are rotatably mounted at the bottom of the housing 1, and the two triangular brushes 6 are arranged on one side of the brush roller 8. Two servo motors are installed inside the housing 1, and the output end of each servo motor is fixedly connected to the shaft of the triangular brush 6 below it;

[0029] In this solution, the triangular brush 6 is driven to rotate by a servo motor, so that the dust on the floor can be gathered. When the dust gathers on one side of the brush roller 8, the rotating brush roller 8 can conveniently sweep it into the dust collection box, thereby effectively improving the cleaning efficiency.

[0030] Reference Figure 1 A cover 4 is mounted on the top of the housing 1 and is located above the dust box;

[0031] In this solution, the cover 4 is assembled on the top of the housing 1, and then the top opening of the dust box is blocked, so that dust can be prevented from floating out when the robot is cleaning. The dust inside the dust box can be collected and processed by opening the cover 4, which is convenient for operation.

[0032] Reference Figure 5, a reserved gap 10 is maintained between the cleaning plate 2 and the wall 9, and in this state, two guide wheels 3 are attached to the wall 9;

[0033] In this solution, when the two guide wheels 3 are attached to the surface of the wall 9, a reserved gap 10 can be left between the cleaning plate 2 and the wall 9, thereby preventing the cleaning plate 2 from contacting the wall 9. When the robot moves along the wall 9, friction resistance can be prevented from being generated on the contact surface between the two, thereby effectively improving the smoothness of the robot's movement.

[0034] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
