Abstract

A cleaning system and a base station. In a working process, an airflow is generated by a drawer, to draw garbage on the ground on a traveling path into a dust box. Before the airflow entering the dust box is discharged outside a cleaning robot, the airflow flows through an air filter, and dust carried by the airflow is filtered out under a filtering function of the air filter. When dust accumulation in the air filter needs to be cleaned or the dust box needs to be emptied, the air filter is driven by a dust cleaner to vibrate, so as to shake off dust in the air filter, and the garbage in the dust box is collected by using a collector of the base station.

Abstract

A centrifugal fan (100), an outer rotor motor and an electric tool. In a heat dissipation process, a fixed portion (110) rotates along with the starting up of a motor body (200) to drive circumferentially arranged blades (120) to rotate, thus driving heat in the motor body to enter air ducts (130) along with an airflow, and discharging the heat out of the centrifugal fan from the air ducts so as to achieve heat dissipation of the motor body. Since flow suppression members (140) are provided in the centrifugal fan, and the flow suppression members are located at the end of a blade assembly facing away from the motor body, then under the suppression of the flow suppression members, the airflow in the air ducts is restricted to flow to the side of the blade assembly facing away from the motor body, thereby preventing the formation of backflow and affecting the total air intake amount in the motor body. By means of the present centrifugal fan, the airflow direction may be effectively improved, the total air intake amount and the effective discharging amount of airflow in the air duct are increased, and the air intake efficiency is increased so as to increase the heat dissipation efficiency of the motor.

Abstract

A cleaning system. In the cleaning system, the relative position of a dust collection box (24) and of a recycling box (31) are set, such that a recycling fan (32) can provide, without the need for using a recycling air duct (4) or merely by means of a relatively short recycling air duct (4), a recycling airflow for recycling and clearing filth in the dust collection box (24). In this way, it is unnecessary to provide a bent air duct between the recycling box (31) and the dust collection box (24); furthermore, the loss of power of the recycling fan (32) is avoided while the recycling fan (32) provides recycling power. A recycling fan (32) having high power can be replaced with a recycling fan (32) having power lower than 550 W, such that the cleaning efficiency of the cleaning system can be ensured, the operation noise of a base station (1) during filth recycling and clearing can also be effectively reduced, and the noise of the cleaning system during operation can thus be reduced to 80 dB or less. Moreover, a base (12) is obliquely arranged in the base station (1), such that the area occupied by the cleaning system in a horizontal direction can be effectively reduced, thereby facilitating the miniaturization design of the cleaning system.

Abstract

The present application relates to a self-moving robot control system, belonging to the technical field of automatic control. The system comprises a self-moving robot and a docking station, the self-moving robot being suitable for moving in a moving area and stopping in the docking station, and the moving area at least comprising an in-boundary area and a guiding line. The guiding line comprises a first end suitable for being arranged in the in-boundary area and a second end suitable for being arranged in the docking station. A position measurement apparatus of the self-moving robot receives a positioning signal to acquire position data of the self-moving robot, a guide line measurement apparatus measures the position of the guide line, and a memory stores map data of the moving area. The map data at least comprises position data of at least one reference point on the guide line. If the position data of the self-moving robot is matched with the position data of the reference point, the self-moving robot executes a docking station entering instruction and/or a docking station exiting instruction by taking the reference point as a transit node. The present application can solve the problem that self-moving robots cannot autonomously return to docking stations or go to moving areas from the docking stations because the positioning accuracy of the self-moving robots is reduced due to interferences to positioning signals of partial areas in the moving areas. The working efficiency of self-moving robots can be improved.

Abstract

An electric tool (100), and a control method for a motor (13) of the electric tool (100). When a pushing handle component (20) is in a working position area and is locked relative to a main unit (10), a signal unit (40) feeds back a first state signal; and when the pushing handle component (20) is in a non-working position area, the signal unit (40) feeds back a second state signal. Upon receipt of the first state signal, the control unit (14) controls the motor (13) to be started according to a first control logic; and upon receipt of the second state signal, the control unit (14) controls the motor (13) to be started according to a second control logic, the second control logic being different from the first control logic. In this way, when the pushing handle component (20) is in a non-working position area, a different startup logic is used to control the motor (13) to be started, so that the probability of false starting of the electric tool (100) due to false triggering of a switch assembly by a user is reduced, and the use risk of the user is reduced, thereby improving the safety of the electric tool (100).
