The dust-gas separation device (20) is provided with a shaft X extending in a front and rear direction in a gas inlet direction, a fan (50) is provided in the body (10), a gas inlet of the body (10) is in butt joint with an gas outlet of the dust-gas separation device (20), and the gas entering direction of the gas inlet of the body (10) and the gas entering direction of the fan (50) in the body (10) are configured to be opposite to each other in the direction of the shaft X. The handheld vacuum cleaner, of which a HEPA (31) is easy to remove, has the advantages of being simple in structure and convenient in use.
A sweeping robot and an automated control method for the sweeping robot, related to the technical field of automated cleaning. The sweeping robot comprises: at least one laser transmitting component (120) and at least one image capturing component (130) provided on a housing (110); and a processing component (140) connected with each laser transmitting component (120) and each image capturing component (130), the processing component (140) being used for acquiring a target image captured by the image capturing component (130). When a projection image of a laser projected on a projection point on an obstacle is present in the target image, contour information of the obstacle is acquired; an obstacle type indicated by the contour information is determined; and the sweeping robot is controlled to sweep according to a sweeping mode corresponding to the obstacle type. This solves the problem of poor sweeping effects due to an existing sweeping robot indiscriminately employing an obstacle avoidance strategy whenever an obstacle is detected. Because the sweeping robot is capable of employing different sweeping modes on the basis of different obstacle types instead of indiscriminately avoiding obstacles by not sweeping, sweeping effects of the sweeping robot are increased.

Disclosed is a press-down-mopping-type floor sweeping robot, comprising: a floor sweeper body (9), wherein a mounting part (90) is formed at the bottom of the floor sweeper body; and a floor sweeper water tank (1) detachably mounted in the mounting part (90), wherein a cleaning cloth is fixed to the bottom of the floor sweeper water tank by means of a hook-and-loop fastener. Press-down assemblies (8) are fixed to two sides of an interior of the floor sweeper body (9) by means of bolts; each press-down assembly (8) comprises a press-down boss (836) capable of elastically extending into the mounting part (90); and the press-down boss (836) elastically presses down on the top of the floor sweeper water tank (1), such that the cleaning cloth can be stably attached to the ground needing to be cleaned in a pressing manner. The problem that the pressure applied to the ground needing to be cleaned by the cleaning cloth is gradually weakened due to the fact that stored water in the floor sweeper water tank (1) continuously flows out of same is solved; and a water pump (60) is mounted in the floor sweeper water tank (1) in an integrated manner, and a first electrifying sheet (41) and a second electrifying sheet (42) supply power to the water pump (60), such that spatial arrangement of the floor sweeper water tank (1) and the floor sweeper body (9) is optimized, and the overall structure of the floor sweeping robot is more compact.

STRUCTURE FOR MOUNTING MOPPING CLOTH TO WATER TANK AND AUTOMATIC SWEEPER
A structure for mounting mopping cloth (2) to water tank and a sweeper. The mounting structure comprises a first guide mounting part (10) formed at the bottom of a water tank (1) of a sweeper, a second guide mounting part (21) fixed on one end of a mopping cloth (2), a first connecting part (31) fixed at the bottom of the water tank (1) of the sweeper, and a second connecting part fixed on the top surface of the mopping cloth (2). The mounting direction of the mopping cloth (2) on the water tank (1) of the sweeper is defined by means of the cooperative connection of the second guide mounting part (21) and the first guide mounting part (10), and the second connecting part is detachably fixed to the first connecting part (31), such that the mopping cloth (2) can be detachably mounted on the bottom of the water tank (1) of the sweeper. The clean water in a water storage cavity (131) can directly wet the mopping cloth (2) by means of the water seepage holes, so that the water exit efficiency of the water tank (1) of the sweeper is improved, and the utilization rate of clean water in the water storage cavity (131) is improved.
