Sweeping robot

Abstract

The invention belongs to the technical field of robots, and particularly relates to a sweeping robot. The sweeping robot comprises a protective shell and a chassis which compose an inner cavity, wherein the inner cavity is internally provided with a driving mechanism, a sensor, a power source, a garbage collecting mechanism and a cleaning mechanism, the cleaning mechanism comprises a cleaning shaft located at a dust collecting port, the two ends of the cleaning shaft are connected with cleaning motors located in the inner cavity respectively, the side face of the cleaning shaft is provided with a cleaning brush, a first auxiliary shaft capable of rotating is arranged between the cleaning shaft and the protective shell in the inner cavity, the side face of the first auxiliary shaft is provided with a plurality of first crushing blocks, the cross section of each first crushing block is of a crescent shape, one ends of the first crushing blocks are fixedly connected to the first auxiliaryshaft, and the other ends of the first crushing blocks are in contacted connection with the cleaning brush. The sweeping robot can assist in cleaning foreign matter wound on the cleaning brush and reduce the incidence of the dust collecting port being caught.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a sweeping robot. Background technique [0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, vacuuming, and mopping the floor are also collectively classified as sweeping robots. [0003] Existing intelligent cleaning machines usually include computers, sensors, motors and power transmission mechanisms, power supplies, vacuum cleaners, cleaning brushes, power switches, operating potentiometers, etc., and three ultrasonic distance sensors...

AI Technical Summary

Problems solved by technology

The cleaning brush is driven by a motor to collect the dust or foreign matter raised by the dusting brush into the dust collection chamber. Wire-shaped foreign matter, such as hair, is entangled, which affects the dust removal effect of the cleaning brush; and, when the sweeping robot is working, it cannot be ruled out that there will be relatively large and hard foreign matter on the ground, so it is often stuck in the place where the cleaning brush is located. The dust collection port affects the work of the sweeping robot
