Description

Brush

Technical field

The utility model relates to cleaning equipment field, particularly relates to a kind of automatic car washing machine, the brush that window-glass scrubber etc. uses.

Background technology

It is rough lumber as the non-foaming wire rod of branch shape that the brush of automatic car washing machine, window-glass scrubber etc., brush bar mostly use the section that is comprised of non-foaming heat moldable resin.Although someone attempts using the sponge clava of continuous air bubbles and felt plate as the substitute of rough lumber, their practicality is not enough.And there is recently the people with the foamed board of the separated foam type of softness directly or be divided into thin bar-shaped rear substitute as rough lumber and use.

But the rough lumber or its substitute that use on above-mentioned convolution brush have following problem:

(1) use the occasion of non-foaming knitting wool, because material is harder, easily scratch application face.Particularly in recent years, be accompanied by the press polish of application face, application face is once there being scuffing obvious especially.The scar that causes when therefore, scrubbing with this brush is just noticeable all the more.

(2) use the occasion of sponge clava and felt plate, because the softness of its material ratio foaming wire rod, the danger of the scuffing that is therefore caused by the hardness problem of material is also just smaller.But because sponge and felt plate self have water imbibition, suction becomes and contacts cleaned object after heavy again, easily damages cleaned object.In addition, in the time of cleaning, the foreign material such as sand can enter in the space of sponge and felt plate, contact so application face again, and not only easily to application face injury, dirt is hoarded in the space, also can shorten the service life of sponge and felt plate self.Also have, the brush that thick sponge clava and felt are tabular, more difficult for the dirt of cleaning slight part, the part of less clean position can get more and more.Becoming the sponge stick of fine strip shape through division processing, is not undercapacity, does not reach due service life, is exactly that toughness is inadequate, and only can become is wrapped on rotary shaft, and does not have the effect of brush.

(3) utilize the foamed board of separated foam type, in the time of the advantage of the sponge that flexible utilization is above-mentioned and the flexibility of felt, solve at the foaming body that uses separated foam the problem brought by water imbibition aspect, obviously utilized the advantage of the foaming felt plate of high-foaming.But even solve by the foaming physical efficiency of utilizing separated foam the problem that water imbibition is brought, but the object of process high-foaming can not prevent in sand and dirt intrusion bubble, so the problem that produces thus also is not solved.Also have, when cleaning with the sponge stick that is divided into fine strip shape with foaming felt plate, the part of less clean position can get more and more.And the process division processing becomes the sponge stick of fine strip shape, and strength and toughness is not enough, does not reach due service life and cleaning effect.

The utility model content

In order to address the above problem, a kind of brush that the utility model proposes comprises brush bar and brush holder, and described brush bar is thermoplastic resin foaming wire rod, and described foaming line section is branch shape.

Preferred as the technical program, described thermoplastic resin stiffness is 1200kg/cm ²-5000kg/cm ²The time, when the foaming line expansion ratio is 1.1-1.7, the brush result of use is better.

Brush best results when more preferably, stiffness is 1300kg/cm2-4000kg/cm2.

Preferred as the technical program, the frothing percentage of described foaming wire rod be 1.1-1.7 doubly.

Preferred as the technical program, described foaming wire rod therefrom heart section to foreign side, have 3 outward extending cross branches at least.

Preferred as the technical program, the thickness of described branch is 0.05mm-0.5mm.

Preferred as the technical program, described foaming wire rod therefrom heart section to foreign side, have 3 outward extending Y-shaped branches at least.

Brush of the present utility model can produce following good technique effect:

(1) impulsive force that produces in the time of alleviating significantly the cleaned object of contact therefore hardly can be to application face injury.

(2) shape with traditional non-foaming wire rod is identical, and toughness and intensity are also roughly the same, so can be right TrickleThe position cleaning puts in place, has good durability.

(3) owing to being low foaming, can expose a large amount of bubbles on outer surface, and be not easy sticking upper sand and the dirt paid, so damage and the low life-spanization of the application face that causes because of sand and dirt also can be prevented.And, because bubble can absorb a large amount of moisture, not only can not affect cleaning after change is heavy, on outer surface, the harsh feeling of appropriateness can increase clean effect on the contrary.

The specific embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, a kind of brush that an embodiment of the present utility model proposes comprises brush bar and brush holder, and described brush bar is that stiffness is 1200kg/cm ²-5000kg/cm ²The section that forms of thermoplastic resin be branch shape, expansion ratio is 1.1-1.7 foaming line doubly.Brush best results when stiffness is 1300kg/cm2-4000kg/cm2.

The hardness of above-mentioned scope when hardness can not excessive damage application face, also has the needed toughness of rough lumber and intensity as the convolution brush.That is to say; angle from protection application face; the material of softwood matter is relatively good; but; in order the time to have enough toughness to scrub off dirt in cleaning, and stretching, friction, impact and bending can bear cleaning the time, and when enwinding with cleaned object; not cut danger, certain intensity is necessary.In addition, because this foaming wire rod section is branch shape, is easy to division and comes.So, must have certain pliability and prevent division.Therefore, in order to satisfy suchlike condition, the stiffness in above-mentioned scope need to be arranged.

The thermoplastic resin that the utility model is mentioned refers to polyolefin or with copolymer or the synthetic of polyolefin with main body, can be the same with traditional non-foaming knitting wool, can pass through the continuous resin wire rod of forming machine extrusion.Wherein, polyethylene and the resin that synthesized take it as main body are also suitable.Particularly low-pressure process is directly locked the shape low density polyethylene (LDPE) and the resin that synthesized take it as main body is best.

And the thermoplastic resin density of using in the utility model is below 0.94, and melt-flow rate is that 0.3-4.0g/10 divides, and particularly is divided into the best with 0.4-3.0g/10.

The section of foaming line is branch shape.This branch shape refers to, as shown in Figure 1, from central part to foreign side, 1 outward extending shape of the limb of at least 3.

This branch shape is the same with always non-foaming knitting wool material, due to such section configuration, and by the surface tension between limb, easy adsorption moisture, the increase of water absorption can improve cleaning effect.And, by the bifurcated of section, even the foaming line of the slice required intensity that also is easy to get comparatively simultaneously, can obtain buffering effect by the thickness of adjusting limb, protection application face.In order to obtain the sort buffer effect, the thickness of limb 1 is take 0.05-0.5mm as best.

The shape of branch except being cross shape shown in Figure 2, can also be the connector of as shown in Figure 33 Y-shaped shapes.The external diameter of a circle of foaming wire rod branch is 0.5-5mm, especially take 1-3mm as best.Diameter is too little, will be not easy to obtain needed toughness.On the contrary, diameter is too large, and the impulsive force of contact cleaned object will become greatly when cleaning, and when easily causing scar, brush also can chap, and easy cleaning is not in place.In addition, the outstanding length of limb 1 take this diameter more than 10% as best.

The foaming wire rod must foam in 1.1-1.7 scope doubly, preferably foams in 1.15-1.5 scope doubly.Expansion ratio is too low, can be the same with non-foaming wire rod always, easily application face is caused scar, and on the contrary, if expansion ratio is too high, not only can not get required strength and toughness, also can easily adhere to sand and dirt.This foaming wire rod is after adding a small amount of blowing agent in above-mentioned thermoplastic resin, uses the forging die extrusion modling the same with desirable section configuration, therefore, can easily produce continuously.This extension ratio that spins is 3.0-6.0 times, especially take 4.0-5.5 degree doubly as best.

The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion by described protection domain with claim.
