Abstract
A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.
Claims16
A handheld cleaning device, comprising:
- a surface-moving portion;
- an upright portion;
- and
- a power battery, configured to supply power to the handheld cleaning device, wherein
- the surface-moving portion is configured to be in contact with a surface to be cleaned and rotatably connected with the upright portion,
- the upright portion is configured to move the surface-moving portion, and
- the surface-moving portion further comprises:
- at least two brushrolls, configured to clean stains on the surface to be cleaned, wherein a rotation speed of each of the at least two brushrolls is less than 3000 r/min;
- a fluid distributor, configured to distribute cleaning liquid to a surface of the at least two brushrolls;
- and
- a wiper unit corresponding to each of the at least two brushrolls, each wiper unit comprising a first wiper and a second wiper, wherein a hardness of the first wiper is greater than a hardness of the second wiper,
- wherein as the at least two brushrolls rotate from a contact position with the surface to be cleaned, stains and dirty water attached to each of the at least two brushrolls are first wiped off by the respective first wiper, and clean cleaning liquid flowing to the at least two brushrolls is then wiped by the respective second wiper, and
- wherein the fluid distributor distributes cleaning liquid to each of the at least two brushrolls between the respective first and second wipers.
