Description
Technical field
The invention provides a kind of cleaner suction nozzle and the dust catcher containing this cleaner suction nozzle.
Background technology
Suction nozzle with round brush is used widely already in dust catcher industry.This suction nozzle is general only with a round brush, comprises a roll body and is planted in the brush silk on this roll body.When High Rotation Speed, the brush silk on round brush can pat the surface of carpet or cloth art furnishings, the dust being positioned at surface or being hidden in surperficial depths is ejected, is convenient to be sucked away.Another critical function of brush silk is the hair that pickup is attached to surface to be cleaned, makes hair enter gas channel and is sucked away.
Such as US Patent No. 6711777B2Hoover discloses a kind of cleaner suction nozzle, a pipeline with round brush shaft parallel is provided with between round brush and turbine, be used for guiding the direction sucking air-flow, can be flown up in the horizontal direction by the hair that the brush silk on round brush evokes and be inhaled into air-flow and take away.Through test fully, we think that the design of US6711777B2Hoover has certain effect to cleaning hair, but perfect not, especially when cleaning carpet, the hair ratio be scattered on carpet is easier to be wrapped on round brush, instead of resembles and be inhaled into air-flow design object and take away.We find that following factor may cause hair to follow round brush to be wound around:
1, on round brush with many bunches of brush silks, every bunch of brush silk generally comprises about 20 monofilament, hair may be sandwiched in the middle of many brush silks of certain cluster, when brush silk rotates along with round brush, centrifugal force can get rid of hair outward, but sometimes the clamping force of brush silk to hair is greater than the centrifugal force and suction that hair is subject to, and causes hair can not depart from brush silk smoothly.The suction of round brush rear Ji Fengmenchu is maximum, but, when the brush silk clipping hair forwards collection air door front to, suction and centrifugal force still may be less than the clamping force of brush silk to hair with joint efforts, cause hair can not depart from brush silk.In addition, because round brush rotating speed is general all up to more than 2000 revs/min, the time that brush silk stops before collection air door only has about 0.01 second, hair may have little time to depart from the middle of brush silk, but follow roll body High Rotation Speed, and because the factor impacts such as suction produce swing in rotation process, be finally wound around around the whole circle of roll body, or firmly care for adjacent brush silk.Hair is more long more easily to be clamped by brush silk and then causes being wound around with roll body.
2, hair is point cantact with the first contacts of brush silk, and hair may snap in the middle part of brush silk, and the centrifugal force that hair is subject in the middle part of brush silk is weaker than the centrifugal force be subject at brush silk tip.For a long hair, only have a very little part with the contact of brush silk, other position of the major part of this hair is also attached on carpet, the pulling force of carpet wool to hair makes it can not fly up swimmingly, but probably follow the collection air door that brush silk strides across round brush rear, and then being drawn High Rotation Speed by brush silk, final neighbour's bunch brush silk of following firmly is cared for, and also may be wound around around the whole circle of roll body.Shag carpet is stronger to the absorption affinity of hair, also more easily causes hair to be wrapped on round brush.
3, conventional suction nozzle adopts single round brush, and in order to avoid the brush silk with High Rotation Speed collides, the leading edge of suction nozzle lower cover is all positioned at the rear of roll body, and the rotational trajectory with brush silk tip keeps the distance of about 5 millimeter.Cleaning carpet in, between round brush rear and lower cover tip this 5 mm wide scope in, carpet wool can be subject to suck air-flow impact and raise, hinder hair with suction air motion.Carpet wool is longer, lifts higher after being subject to suction, more obvious to pilomotor inhibition, and this also makes hair more easily follow brush silk and strides across collection air door being wound around with round brush.
Standard vacuum can pick up the bowling of about 9 pound weights, and suction is enough powerful, if hair is in free state, it can siphon away by dust catcher easily.Free state is in order to allow hair, will guarantee that it does not stick on carpet wool, do not stopped by carpet wool, between the brush silk not being clipped in round brush, do not care between adjacent brush silk, do not follow brush silk and stride across collection air door, but after surface to be cleaned is picked up, just can be departed from brush silk smoothly by brush silk, then just can guarantee that it is sucked away yet.
