Description

Plastic hair for suction cleaner head

The design relates to a kind of cause that is intended to improve because of suction nozzle hairbrush cilium to be made the suction head of suction cleaner hairbrush not only frictional resistance is big, and is difficult to dispose the cotton-shaped dirt bits attached on the carpet, as: the novel brush cilium of hair, the end of a thread, cotton-wool etc.

The suction head of suction cleaner hairbrush that comes out is generally hair on the neck formula cilium hairbrush now, and a problem is arranged here, though hair on the neck formula cilium is the bunchy structure exactly, dynamics is bigger, but for sticking to cotton-shaped dirt bits on the carpet or 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 cilium 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 even changed the flexible class of hairbrush, often also is that these dirt bits 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 design's purpose is to change the situation that suction nozzle is ineffective because of the cause dedusting of hairbrush and waste time and energy by reform suction nozzle hairbrush cilium (new-type hairbrush of then change that has gone on the market or the new-type suction nozzle of supporting assembling).

The design's purpose reaches like this:

At first select the material raw material of the strong plastics of not only pliable and tough but also high resilience and stretching resistance for use as suction head of suction cleaner hairbrush triangular band tooth plastics cilium, if necessary, for the elasticity and the stretching resistance that make cilium is stronger, can add a finer wire or thin copper wire along vertical direction at the center of cilium main body.

Then, be on the moulded structure Design of cilium, mainly be to realize above-mentioned purpose in the design of modeling structure of appended from it tooth, that is, the design's triangular band tooth plastics cilium is " standard " triangular prism body.(because cilium main body essence is the isosceles trapezoid body, but extremely narrow because of base on it, might as well regard the triangular prism body as).Cilium is most advanced and sophisticated to be " standard " triangular pyramid body (its essence is the rectangular pyramid body, extremely narrow because of a side side of its cone, might as well regard a lateral edges of triangular cone as, so also can be by the processing of triangular pyramid body).The cilium main body adopts the prismatic figure modelling, is because triangular structure is the most stable modeling structure, both can guarantee not flexible type (plastics are easily aging) of cilium, can make its be easy to restore to the original state (becoming lodging into upright) again.

(being the last base of isosceles trapezoid body) adheres to the tooth of some different shapings on the outside side incline of cilium prismatic main body, and a kind of is that the tooth of isosceles triangle is last, near the tip of cilium; Another kind is that the tooth of right angled triangle is descending, near the root of cilium.Be the intermediate zone of not being with any tooth between two kinds of teeth, the adhering mode of tooth is a depressed.Below the right angled triangle tooth, be the root of cilium main body, root is not with tooth.The quantity of these two kinds of teeth requires the tooth of isosceles triangle to Duo about one times than the number of teeth amount of right angled triangle approximately, and the sum of these two kinds of teeth should not be arranged too much, otherwise can produce the excessive adverse consequences of frictional resistance enough to tackle the dirt bits degree of being that should remove.The total length of triangular band tooth cilium requires: when the low gear position of suction head of suction cleaner hairbrush at flexible retaining time, should guarantee that the tip of triangular band tooth cilium and the tooth of the part or all of isosceles triangle below the tip expose outside the hairbrush mouth, purpose is the general dirt bits of removing on carpet pile depths and the carpet surface.And when the flexible class of hairbrush during in high-grade position, should guarantee that then the intermediate zone of triangular band tooth cilium and the tooth of part or all of right angled triangle also expose outside the hairbrush mouth, purpose mainly is in order to tackle the cotton-shaped dirt bits of extremely difficult cleaning, certainly this is effective too to clearing up other dirt bits, but the frictional resistance of right angled triangle tooth bigger slightly than isosceles triangle tooth.So should not too much use.

The structure of lance tooth and shape-designing are the design the most basic most important aspects.Because the method with the dedusting of band tooth cilium hairbrush is different from the method for using the dedusting of hair on the neck formula cilium hairbrush fully, the latter relies on the tip of cilium to come dedusting, but cilium is in case lodging is in operation considered to be worth doing just inoperative for the cotton-shaped dirt that sticks on the carpet.The former then utilizes cilium to be easy to the characteristic that lodges in operation just, scrapes the purpose of getting dirt bits and reach by means of leg-of-mutton tooth accompanying on the cilium incline, and to get cotton-shaped dirt bits effective especially for scraping for the tooth of right angled triangle wherein.Because the crown of right angled triangle tooth and vertical plane to the straight flange of carpet for cotton-shaped dirt bits to scrape attached power extremely strong, be easy to it is scraped get, collect, and suck for suction nozzle.

The purpose of design is achieved in that the triangular band tooth cilium on the suction nozzle hairbrush, in the dust catcher operating process, be pushed when pulling into the lodging shape, tooth on its incline then keeps vertical or is bordering on vertical configuration with carpet, as dirt bits being used to remove, then hairbrush is in low gear position, at this moment, the first half of cilium exposes the hairbrush mouth, some isosceles triangle teeth on it (its frictional resistance is equivalent to some manes, but more than tens of be few many of the radical of a branch of hair on the neck formula cilium, so frictional resistance can be very not big), together the dirt bits of general dirt bits and carpet pile depths are scraped with the cone tip of cilium and to be swept, for the suction nozzle suction.As in order to remove cotton-shaped dirt bits, then make hairbrush be in high-grade position, the Lower Half of its cilium is also exposed the hairbrush mouth, and the right angled triangle tooth on it because of the dynamics that moulding determined, can tackle these the most cotton-shaped dirt bits of difficult cleaning effectively.The method that tackles different dirt bits with two kinds of different teeth is not only easy but also effective, thereby reaches clean, the time saving and energy saving purpose of dedusting.

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, its both sides all have tooth.Triangular band tooth plastics cilium can be combined into the hairbrush that single file, duplicate rows or multirow are arranged cilium in pairs.

The design's concrete modeling structure is done by accompanying drawing and is described in further detail:

Fig. 1 is the longitudinal side schematic diagram of a pair of bunchy cilium.

With reference to Fig. 1: the integral body (1) (2) (3) (4) (5) (6) of triangular band tooth cilium is to be added a bullet cilium tip (1) and gone up some isosceles triangle teeth (2), right angled triangle tooth (5) and not toothed intermediate zone (3) that depressed adheres to and root (6) formation at the outside side incline of cylindrical bodies (4) (being the last base of isosceles trapezoid cylinder) by " standard " triangular prism shaped main body (being the isosceles trapezoid cylinder) (4).The cross section (not drawing among the figure) of " standard " triangular cilium cylindrical bodies (being the isosceles trapezoid cylinder): go up the base, being the extremely narrow lateral end of cone tip (1) and the crown width of lance tooth, also is the outside incline end face width about 0.2 millimeter (all not drawing among the figure) of not toothed intermediate zone (3) and root (6).The bottom is the lateral width of the cilium cylindrical bodies relative with toothed lateral edges about 1.5 millimeters (not drawing among the figure), and two waists are two lateral width about 1.914 millimeter (in figure do not draw) adjacent with toothed lateral edges.Most advanced and sophisticated positive (not the drawing among the figure) at cilium cone tip (1): the cone baseplane is an isosceles trapezoid, last base (being the extremely narrow lateral end of cone base) is wide about 0.2 millimeter, wide about 1.5 millimeters of bottom (side of promptly relative with cilium outside incline cylindrical bodies), two waists (being two waist sides of cilium isosceles trapezoid cylinder) are wide about 1.914 millimeters.The cone tip is at the place, neutrality line center of bottom surface isosceles trapezoid, and high (most advanced and sophisticated vertical range to the baseplane) is 2 millimeters (all not drawing among the figure).

The arrangement of tooth and dimensions: the bottom at the adjacent cilium cone of the tooth of isosceles triangle tip (1) is arranged in order downwards along the last base of isosceles trapezoid cylinder, quantity at most must not be above 5, otherwise can increase frictional resistance, and, hypotenuse (lateral elevational view of not drawing among the figure) its dedusting effect that the extremely narrow lateral end of its apex partis petrosae bottom portion is identical with adhere to the waist with the isosceles triangle tooth that produces because of the depressed of isosceles triangle tooth and single isoceles triangle tooth (2) basic identical.0.5 millimeter of the tooth depth of isosceles triangle tooth, tooth root links to each other, two waists of tooth respectively are about 0.56 millimeter, 0.5 millimeter of crown spacing (being that tooth root is long), and crown is not cilium main body horizontal longitudinally wide (being the last base of isosceles trapezoid cylinder) about 0.2 millimeter (drawing among the figure).The root (6) of the close cilium of right angled triangle tooth (5) upwards is arranged in order to the vertical concave side of intermediate zone (3) along the last base of isosceles trapezoid cylinder, and the right-angle side of tooth is towards the root of cilium, and hypotenuse is towards the tip of cilium.The quantity of this tooth must not be above 2, and the end of the intermediate zone (3) adjacent with right angled triangle tooth (5), the straight flange plane (not drawing among the figure) of adhering to vertical recessed its shape of ladder plane (not drawing among the figure) that produces and right angled triangle tooth (5) because of the depressed of tooth is identical, also can play and the essentially identical effect of single right angled triangle tooth (5).0.5 millimeter of the tooth depth of right angled triangle tooth (being the length of straight flange), tooth root links to each other, the hypotenuse of tooth is about 1.12 millimeters, 1 millimeter of crown spacing (being that tooth root is long), and crown is not cilium main body horizontal longitudinally wide (being the last base of isosceles trapezoid cylinder) about 0.2 millimeter (drawing among the figure).

Be that not toothed intermediate zone (3) is about 3 millimeters between isosceles triangle tooth and right angled triangle tooth, there is a hypotenuse identical with the waist of isosceles triangle tooth the upper end of intermediate zone (3), there is a vertical recessed straight flange identical with the right angled triangle tooth lower end, and this straight flange can play and the essentially identical effect of single right angled triangle tooth (5).

With reference to Fig. 1, triangular band tooth cilium should two in pairs, be combined as bundle back to (4) (8), back to about 0.5 millimeter of spacing.After being combined as bundle in pairs, the row of being combined as that embarks on journey again, after the row of being combined as, tooth (not drawing among the figure) all is with in its both sides like this.Triangular band tooth cilium row's length can with former suction head of suction cleaner hairbrush cilium row's length identical (not drawing among the figure).Width is if two bunchy single files are arranged about 4.1 millimeters.Also can duplicate rows or multirow arrange cilium, but only have tooth in total both sides of arranging, promptly Zhong Jian cilium can be with tooth.The making material of triangular band tooth cilium is not only pliable and tough but also high resilience and the strong plastics of stretching resistance, for increasing elasticity and stretching resistance again, can add the finer wire or the thin copper wire (not drawing among the figure) of about 0.1 millimeter of diameter along vertical direction if necessary at the center of cilium main body.

With reference to Fig. 1, as each side (not drawing among the figure) of " standard " triangular prism body (being the isosceles trapezoid cylinder) of cilium main body (4) and depressed being strengthened attached to the dimensions of the lance tooth (2) on the outside incline (being the last base of isosceles trapezoid cylinder) and (5) etc. or dwindling, be called the maximization or the miniaturization of triangular band tooth cilium specification.
