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

Embodiment Construction

[0041] The specific implementation forms of the vacuum cleaner nozzle and the vacuum appliance involved in the present invention will be described in detail below with reference to the accompanying drawings.

[0042] In this embodiment, the vacuum cleaner includes: a vacuum cleaner nozzle 10, an air duct connecting portion, and a main body including a dust collecting mechanism. The suction nozzle 10 of the vacuum cleaner is matched with the connecting part of the air duct, and is used to clean hair and dust on surfaces to be cleaned such as carpets and sofas. The main body containing the dust collecting mechanism provides suction force for the vacuum cleaner nozzle 10 to absorb and store the hair and dust cleaned by the vacuum cleaner nozzle 10 .

[0043] Such as figure 1 , 2 , 3, 4, 5, 6, 7, and 8, the vacuum cleaner nozzle 10 includes: a body 11, a rolling brush assembly 12, a driving member 13, and a hair scraping member 76 (see Figure 5 b and Figure 8 ). The body 11...

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...
