Abstract
A cleaning tool, including a suction pipe, a brush head outer casing, a motor casing, and a brush head. The cleaning tool further includes: a brush head inner casing, which is relatively rotatably provided in the brush head outer casing and forms an accommodation cavity of the brush head; and a bottom plate, which is integrally formed with the brush head inner casing and forms a cleaning contact surface of the cleaning tool. The bottom plate includes a front raised portion and a rear raised portion.
Claims18
A cleaning tool, comprising a suction pipe, a brush head outer casing, a motor casing, and a brush head, wherein the cleaning tool further comprises:
- a brush head inner casing, relatively rotatably provided within the brush head outer casing and forming an accommodation cavity of the brush head;
- and
- a bottom plate, integrally formed with the brush head inner casing and forming a cleaning contact face of the cleaning tool;
- wherein
- the bottom plate comprises a front raised portion and a rear raised portion;
- an end of the rear raised portion is provided with a rib to form a limit at a position where the rear raised portion is rotated to be contacted with the motor casing;
- and
- an air guide port is provided on an upper portion of the brush head inner casing, an opening span of the air guide port along a circumferential direction have no effect on suction efficiency of the suction pipe of the brush head outer casing when the brush head inner casing rotates relative to the brush head outer casing, and an area of the air guide port is greater than an area of an inlet of the suction pipe;
- wherein a front opening edge of the air guide port is configured such that when a front edge of the brush head outer casing abuts against the bottom plate, a front edge of the inlet of the suction pipe is at least flush with or does not forwards exceed the front opening edge;
- a rear opening edge of the air guide port is configured such that when a rear portion of the motor casing abuts against the rib, a rear edge of the inlet of the suction pipe is at least flush with or does not backwards exceed the rear opening edge.
A cleaning device, comprising a cleaning tool, wherein the cleaning tool comprises a suction pipe, a brush head outer casing, a motor casing, and a brush head;
- wherein the cleaning tool further comprises:
