Dust collector suction nozzle and dust collection appliance

Abstract

A vacuum cleaner nozzle with a brushroll and a vacuum appliance comprising the vacuum cleaner nozzle. The vacuum cleaner nozzle (10) is characterized by: a body (11) having a wind passage portion and a hollow portion; a brushroll component (12), comprising a roller portion, a conveyance belt (32), and a plurality of bristle units; a hair scraping member (76), located inside the hollow portion; and a driving member (13), where the roller portion at least has a front roller (30a) and a rear roller (30b), the front roller (30a) is provided above a dust suction opening, the rear roller (30b) is provided near the wind passage portion, the hair scraping member (76) has at least one scraper (72), and an end of the scraper (72) is provided near the rear roller (30b) and extends between two adjacent bristle units in an axial direction of the roller portion. When the brushroll component (12) rotates at a high speed, the hair scraping member can scrape hair off bristles (33), so that hair that drops in a dust suction air flow passes through the wind passage portion is sucked into a dust collection apparatus instead of being wound around the brushroll component or tangled between adjacent bristles (33).

Description

technical field [0001] The invention provides a vacuum cleaner nozzle 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 suction nozzle generally only has a rolling brush, which includes a rolling body and brush filaments planted on the rolling body. When rotating at a high speed, the brush filaments on the roller brush can slap the surface of the carpet or fabric furniture, arousing the dust located on the surface or hidden in the depth of the surface, so that it can be sucked away. Another important function of the brush filament is to pick up the hair attached to the surface to be cleaned, so that the hair enters the airflow channel and is sucked away. [0003] Such as U.S. Patent US6711777B2Hoover discloses a kind of suction nozzle of vacuum cleaner, is provided with a pipeline parallel with the rotating shaft of rolling b...

Problems solved by technology

The longer the hair, the easier it is to be pinched by the brush wire and cause entanglement with the roller

[0005] 2. The initial contact between the hair and the brush filament is only a point contact, and the hair may be stuck in the middle of the brush filament. The centrifugal force on the hair in the middle of the brush filament is weaker than that on the tip of the brush filament

Long-pile rugs hold hair more tightly and are more likely to cause hair to tangle up on the roller brush
