Description

Electrically powered hand held hair curling applicance

The present invention relates to electrically powered hand held hair curling applicance.This curler comprises a handle, can hold curler by this handle; A reel that stretches out from handle, hair twists in above it, and reel is a hollow, and fluid is therefrom flow through.Porose on the reel, fluid is outwards flow on the hair.Drum diameter is adjustable, both can enlarge fully, can dwindle fully again, so that form the volume flower of different-diameter.

The application people discloses above-mentioned this class curler for DT-A-2528822 and the DT-A-2529016 (latter is that the former additional applied for a patent) of Hubner.But the curler of Hubner uses steam as fluid, its reel is the hollow porous circular cylinder of fixed diameter, is that middle heart is equipped with many semicircular cylinder sheets with holes in the reel outside with axle, this sheet can be that the center is outwards rotated and increased drum diameter together with the axle, or inwardly rotates and reduce drum diameter.

There are many deficiencies in the curler of Hubner.At first, even the reel of Hubner is when drawing in fully, diameter is still bigger.Bigger diameter is caused by its structure, because the included halfround bar slice of reel is fixed on the cylinder outside, its minimum diameter is 20 millimeters.This value is bigger in the diameter range of desirable volume flower.Secondly, the Hubner curler adopts a small amount of low-pressure steam blow head to send out.For main situation about drying up with shaping hair with dry hot blast is unfavorable.Especially the air-flow of Hubner curler needs to move back to path through one and comes out from cylinder inside, just enters zone between cylinder and the halfround bar slice through a round, and then flows out through another round, blows on the hair again.Two rounds do not line up usually mutually.At last, the Hubner curler exists condensation problem, and the globule can be fallen on the hair from curler.

The US-A-3 of Barradas, 921,648 have also described the curler of the above-mentioned type.This curler is a kind of steam curling tongs, and its reel comprises the cylinder of a hollow porous fixed diameter.A porous, expandable, resilient stainless steel shaft are equipped with in the reel outside.

The shortcoming of the curler of Barradas is identical with the Hubner curler: because double-decker makes that its diameter when drawing in fully is bigger; Two rounds do not line up and cause path circuitous, are unsuitable for the heated dry air stream with big flow; And cohesion also causes the globule to drop on the hair.

Purpose of the present invention will be improved above-mentioned this class curler exactly, makes it when drawing in fully, and diameter reduces than existing apparatus is obvious.Another object of the present invention will be improved above-mentioned curler exactly, and it can be blown to a large amount of hot dry winds on the hair.

The reel of curler provided by the present invention comprises a plurality of elongated reel element, and these elements are radially arranged with equidirectional each other, forms axisymmetric reel substantially.These reel element can inwardly and outwards radially be moved together, so that make the reduced and the expansion of reel.In complete expanded state, reel element is connected with each other, and forms basic closed reel.In deflated state, each reel element in the reel of basic closure is overlapping.When reel for launching fully, draw in fully or when being arbitrary intermediateness, reel element with holes can making fluid flow directly on the hair from the inside of reel.

Curler of the present invention has many advantages.The first, its structure can make drum diameter dwindle.The second, mass air flow can directly flow on the hair from reel inside.

Fig. 1 is a blowing hot wind brush side view of the present invention, and this blowing hot wind brush comprises the reel that diameter is adjustable, and reel is in deployed condition among the figure;
