Cleaning robot and floor treatment device

Abstract

A cleaning robot comprising a robot machine body (100). Drive wheels (110) are arranged on the machine body (100). A dust intake opening (120) is provided at the bottom part of the machine body (100). With the direction in which the cleaning robot travels serving as the front (A), a static seal (130) is arranged at the rear and two sides of the dust intake opening (120). The lower edge of the static seal (130) extends towards a to-be-cleaned work surface (B). A dynamic sealing element (140) is arranged at the front of the dust intake opening (120). The dynamic sealing element (140) comprises an actuating element (141) and a dynamic seal (142). A gap between the dynamic seal (142) and either the edge of the dust intake opening (120) and / or the to-be-cleaned work surface (B) forms an air intake opening. The dynamic seal (142) is driven by the actuating element (141) into motion, thus allowing the area of the air intake opening to change dynamically. By arranging the dynamic sealing element (140) at the dust intake opening (120), not only the dust intake opening (120) is provided with a sufficient degree of vacuum, but also the dynamic sealing element (140) does not obstruct dust particles from reaching the dust intake opening (120), thus allowing for a simplified structure and increased cleaning efficiency.

Description

technical field [0001] The invention relates to a cleaning robot and a ground treatment device, which belong to the technical field of small household appliance manufacturing. Background technique [0002] Sweeping robots are emerging household appliances that can automatically clean the ground while walking. The cleaning robot sucks dust from the surface to be cleaned through the suction generated by the motor installed in the main body. In order to ensure a sufficient vacuum between the surface to be cleaned and the suction port, a sealing strip is usually provided at the suction port. [0003] If the walking direction is set to the front, the existing cleaning robots on the market are generally only equipped with sealing strips at the rear and both sides of the suction port. The disadvantage of this structure is that the front of the suction port is not sealed, which greatly reduces the If the vacuum degree of the vacuum cleaner is reduced, some difficult-to-remove dust ...

Problems solved by technology

[0003] If the walking direction is set to the front, the existing cleaning robots on the market are generally only equipped with sealing strips at the rear and both sides of the dust suction port. The disadvantage of this structure is that the front of the dust suction port is not sealed, which greatly reduces If the vacuum degree of the vacuum cleaner is reduced, some difficult-to-remove dust will accumulate in the dust suction port and the dust suction channel, and the dust suction effect will be poor.

However, if a sealing strip is installed on the front of the cleaning robot's suction port, the sealing strip will prevent dust or debris from reaching the suction port during the cleaning process, affecting further cleaning.
