Vacuum cleaner nozzles and vacuum cleaners

Abstract

Provided are a vacuum cleaner nozzle (10) with a rolling brush (12) and a vacuum cleaner (100) having the vacuum cleaner nozzle (10). The vacuum cleaner nozzle (10) comprises: a body (11), which has an air channel section, an air damper (56) for introducing air into the air channel section, and a hollow front end part located on the outside of the air damper (56) and provided with a suction opening (61); a rolling brush (12), provided in the hollow front end part and comprising a rolling body (22) and a plurality of brush bristles (23) mounted on the rolling body (22); and a driving member (13) for driving the rolling brush (12) into continuous rotation. The length of the air damper (56) is not less than the length of the region where the plurality of brush bristles (23) is distributed on the rolling body (22) in an axial direction; the air channel section has an interface member (50) connected to an air channel connection part (101) and a sucked-in-air induction channel (60) which introduces air entering the air damper (56) from the suction opening (61) and through the rolling brush (12) into the interface member (50); the sucked-in-air induction channel (60) is symmetrical from left to right in an air intake direction, and has a front guide part (60a) in communication with the air damper (56) and a rear guide part (60b) in communication with the interface member (50); and the length of the front guide part (60a) is not less than the length of the air damper (56), and the front guide part (60a) extends a certain distance in a direction directed towards the interface member (50).

Description

technical field [0001] The invention provides a vacuum cleaner nozzle with a rolling brush and a vacuum appliance containing the vacuum cleaner nozzle. Background technique [0002] Suction nozzles with rolling brushes have long been widely used in the vacuum cleaner industry. This type of roller brush consists of a roller body (usually cylindrical) and brush filaments placed on the surface of the roller body. When rotating at high speed, the brush filaments can beat the surface of the carpet or fabric furniture, and remove the dust on the surface of the carpet or hidden in the depth of the carpet. Excited, ready to be sucked away. At the same time, the brush wire can also pick up the hair and fluffy dust on the surface of the carpet or fabric furniture. However, the suction nozzle of the traditional roller brush is more suitable for granular dust, which can excite them from the depths of the carpet and suck them away, while hair and fluffy dust are easier to wrap around t...

AI Technical Summary

Problems solved by technology

For the hair raised by the brush filaments on both sides of the roller brush, it is not only agitated by these filaments, but also blocked by the housing, and is also attracted by the air flow, and is also affected by other brush filaments in the process of leading to the air outlet of the suction nozzle. In these processes, longer hairs tend to wag their tails and are not easily sucked away by the airflow, and may eventually become entangled with the roller
