Multifunctional floor brush

Abstract

The invention relates to a multifunctional floor brush comprising a floor brush surface cover, a floor brush base plate, an air inlet arranged on the floor brush base plate and for dust-containing air flow entrance, and a floor brush connection pipe connecting a dust collector. A brush bar scraping dust on the floor and a first elevating structure driving the brush bar to move up and down are arranged close to the air inlet, and a second elevating structure lifting the floor brush base plate to change a distance between the floor brush base plate and the to-be-cleaned floor. The multifunctional floor brush can meet a demand of high dust collecting capacity of ERP and use comfortableness and flexibility under different conditions; mobile resistance of the floor brush can be reduced; large particles can be easily absorbed, so damage to the floor by large particles can be reduced; and the multifunctional floor brush has great practical meaning.

Description

technical field [0001] The present invention relates to a multi-functional floor brush, especially suitable for use in various ground conditions to be cleaned and requiring high cleaning ability and comfort, and the floor brush of the vacuum cleaner required by the EU ERP (Energyrelated Products) test recently. Accessories. Background technique [0002] The floor brush of the vacuum cleaner is the most important part of the vacuum cleaner, which is used to absorb the dust on the ground. In the process of work, there are usually two functions. One is to scrape the dust on the ground and play the role of raising dust. It is mainly to scrape up the stains and sticky dirt on the ground. The dust is collected into the hose of the vacuum cleaner and flows into the dust collection chamber of the vacuum cleaner to achieve dust removal. Therefore, a large part of the cleaning ability of the vacuum cleaner on the ground to be cleaned depends on the accessory floor brush of the vacuu...

AI Technical Summary

Problems solved by technology

[0005] But the problem is that after reducing the distance between the air inlet and the floor to be cleaned, in actual use, when the floor is in use, it often leads to large particles of dust that cannot enter at all, and get stuck between the bottom plate of the floor brush and the floor to be cleaned. Scratch the floor, and at the same time, the position of the air inlet has a high degree of vacuum, and the movement resistance of the floor brush on the floor is also large

When the carpet is being cleaned, under the action of the negative pressure of the vacuum cleaner, the bottom plate of the floor brush is in close contact with the carpet. At this time, the vacuum degree of the air inlet of the floor brush is at a high value. Although this can improve the dust removal ability of the floor brush of the vacuum cleaner on the carpet, but at this time If the air permeability of the carpet encountered is not good, it is difficult to push the floor brush to move. In practice, it is impossible to push it at all, that is to say, the vacuum cleaner cannot be used at all.
