Abstract

The utility model discloses a novel fiber of the sucking head brush of a vacuum cleaner, which uses elastic and strong stretching resistant plastic as the main material; a main body is in a triangular prism shape, and a plurality of triangulated-shaped teeth are arranged on the lateral edge of single side below the cone tip of the fiber. Once the fiber body which adhere to the teeth is lodged in the operation, various dust which adhere to the carpet can be effectively swept; specially the floccus and dust are scraped and swept for the sucking of the sucking head, and the dust removing efficiency is enhanced greatly. In order to realize the effect better, two of the kind of fibers are bundled back to back to form a novel brush fiber row having teeth at both sides.

Description

Triangular tooth-like plastic fibre of sucking head brush of vacuum cleaner

The design invention relate to a kind of be intended to improve make the dust catcher be difficult to remove cotton-shaped dirt bits attached on the carpet because of the work of suction nozzle hairbrush is ineffective, as the new-type hairbrush cilium of hair, the end of a thread, cotton-wool etc.

The suction head of suction cleaner hairbrush that comes out generally all adopts the animal mane to do the hairbrush cilium now.A problem is arranged here, is exactly the animal mane of bunchy, though dynamics is bigger, for the cotton-shaped dirt bits that stick on the carpet, still powerless.And regardless of dust catcher suction size.Because in operating process, because the relation of push-pull effort, it vertically is the shape that lodges that mane on the hairbrush becomes, pressed in the past from the cotton-shaped dirt bits of the fiber-like of strong adhesion often, and push-and-pull repeatedly, often also be that these soft flocks have been twisted into strip, also handy hand is plucked, even the latticing shape that has is not rubbed with the hands not come out yet.

The purpose of the design's invention is to change suction nozzle because of the ineffective situation of the cause work of hairbrush by reform suction nozzle hairbrush cilium (the new-type hairbrush of then change that has gone on the market).

The purpose of the design's invention reaches like this: at first, select for use neither can fracture and strong high resilience, and the sort of plastics that are similar to the plastics cilium on the toothbrush anti-ageing, that stretching resistance is strong are done the material raw material of new-type suction nozzle hairbrush cilium.Preferably the pedestal of hairbrush cilium is also selected identical material for use, so not only has been convenient to whole processing and fabricating (as the injection moulding form) but also has made itself to have had certain stretching elasticity.Help the prolongation of cilium whole service life.

Be that moulded and structure Design from cilium realizes above-mentioned purpose then.Promptly, the hairbrush cilium of the design's invention is a triangular band odontoid, it is because triangular structure is the most stable modeling structure that the cilium main body adopts triangular prism body (most advanced and sophisticated is the triangular pyramid body), both can guarantee not flexible type (the easily aging modification of plastics) of cilium, can make its be easy to restore to the original state (becoming lodging) again into upright.

On a side incline of triangular cilium, adhere to the plurality of tooth-shaped burr.The shape of tooth is a right angled triangle, crown up, perpendicular to the cilium main body, below the cilium bullet, arrange to root successively along cylindrical body, can be discharged to root always, but, all should have the profile of tooth burr on the one-sided incline at all positions that can expose suction nozzle hairbrush mouth of cilium.

Most important, the most basic aspect that the invention of profile of tooth burr is that the design invents.Because method with the dedusting of band tooth cilium hairbrush, be different from method fully with the dedusting of mane hairbrush, the latter relies on the tip of cilium to come dedusting, and be to strengthen this effect by means of the population effect of boundling, but cilium is in case lodging is just inoperative for the cotton-shaped dirt bits that stick on the carpet.The former then utilizes cilium to be easy to the characteristic that lodges in operation just, scrapes the purpose of sweeping dirt bits and reach by means of leg-of-mutton tooth accompanying on the cilium incline, and to sweep cotton-shaped dirt bits effective especially for scraping for this.Because after the lodging of cilium main body, the tooth of the right angled triangle on its incline just touches is scraped the dirt bits of sweeping, its crown and straight flange for cotton-shaped dirt bits to scrape attached power extremely strong, get and it is scraped, collect, suck for suction nozzle, simultaneously, other dirt bits are scraped the effect of sweeping also not second to the mane tip of bunchy.And if cilium non-lodging or lodging angle are very little, then the crown of the part lance tooth at the cone point of cilium and adjacent tip also can play and the most advanced and sophisticated similar effect of mane formula cilium, so its dedusting effect outclass mane formula cilium.And because the invention and the design of profile of tooth burr, it is dynamic to make no matter cilium main body itself is in which kind of, can not influence the dust collection capacity of these teeth, and like this, no matter whether cilium lodges, and can both give play to normal dedusting effect.

The design invention is achieved like this: the triangular band tooth cilium on the suction nozzle hairbrush, in the dust catcher operating process, be pushed when pulling into the lodging shape, and the profile of tooth burr on its incline then keeps vertical or barb-like with carpet.This operating angle and profile of tooth burr be because of the dynamics of shape relation decision, and the cotton-shaped dirt bits of the most difficult cleaning that just is enough to require great effort are scraped and swept, and for the suction nozzle suction, thus reach dedusting totally, save time, the labour-saving purpose.

In order to achieve the above object better, triangular band tooth cilium be by two back to becoming a branch of structure, like this combination in a row after, all there is the profile of tooth burr its both sides.Triangular band tooth plastics cilium can be combined into the hairbrush that single file, duplicate rows or multirow are arranged cilium in pairs.The concrete modeling structure of the design's invention is done by accompanying drawing and is described in further detail:
