4-segment type sweeping robot

Abstract

The invention relates to a four-stage sweeping robot, comprising a power supply system, a motor system, a sensor system, a control system and a sweeping system which are arranged on the rounded base plate, wherein the sweeping system comprises a front main brush device and a rear main brush device respectively on the front portion and the read portion of the base plate, a left side brush device and a right side brush device respectively on the left portion and the right portion of the base plate, and a vacuum dust cleaner device on the back side of the base plate; the front main brush device and the rear main brush device provided with a dust collection chamber respectively and driven by a separated motor, and a side brush and a main brush which share a motor, constitute an independent sweeping system. Two sets of sweeping systems can be operated together or independently. The four-stage sweeping process comprises a step of sweeping dust into the bottom of the robot by the side brush, a step of sweeping dust into the dust collection chamber by the front main brush, a step of sweeping dust into the dust collection chamber by the rear main brush, and a step of drawing residual dust into the filtering chamber by the vacuum cleaner device. The inventive four-stage sweeping robot solves the problems of incomplete cleaning and susceptibility to blockage of the main brush caused by the prior robot design.

Description

technical field [0001] The invention relates to an indoor cleaning robot, in particular to a four-stage cleaning robot. Background technique [0002] The cleaning robot, also known as the vacuum robot, combines mobile robot and vacuum cleaner technologies, and is currently the most challenging and popular research and development topic in the field of household appliances. Since 2000, the commercial products of cleaning robots have been launched one after another, becoming a new type of high-tech product in the field of service robots, with considerable market prospects. [0003] Japan's Hitachi has been developing vacuum cleaners since the late 1980s. Panasonic of Japan, Samsung of South Korea, LG, Hanool Robotics, Electrolux of Sweden, Philips of the Netherlands, Karcher of Germany, Dyson of the United Kingdom, Floorbotics of Australia, Uleka of the United States ( Eureka), iRobot, Evolution Robotics and other companies are or have actively developed and provided some sa...

AI Technical Summary

Problems solved by technology

Most of the existing cleaning robot products use a single main brush and a vacuum suction device. The disadvantage is that the suction and sweeping are integrated, the main brush becomes an obstacle to vacuum suction, the suction port is too large, the suction is insufficient, and the cleaning is not clean

The Roomba of iRobot in the United States is currently the product with the largest market share. The patent US 6,883 201B2 "Autonomous Floor Cleaning Robot" announced its three-stage cleaning technology, which improves the shortcomings of the single main brush's sweeping and suction integration. The disadvantages are Dust tends to accumulate on the side of the auxiliary brush. Excessive dust will fall on the floor, and it may also clog the auxiliary brush

Because the main brush and the auxiliary brush share the same motor control, if a brush is blocked, the cleaning work will be interrupted
