Definitions
- the invention relates to a type of dental hygiene brush with two bristle-carrying Heads, as is known from patent specification P41 159 43.8, to produce them.
- the new technical possibility also concerns mechanically moving double-head brushes for electromechanical drive devices etc.
- the double-head brush for gum massage and tooth cleaning enables one Appropriate massaging both sides of the gums and cleaning the teeth on the inside and Outside.
- the bristle ends are effective Exercise two sides of the gum tissue by contact, which gums and teeth treated equally.
- the inner and outer tooth surfaces are also cleaned all around at the same time and guides thus for an even tooth cleaning from both sides.
- the 2 bristle-bearing Legs of the double-head brush guide and adapt themselves to the rows of teeth, so that an uncomplicated cleaning in the entire dental room is possible and guaranteed.
- Double-head brushes are made from one piece, but there is no possibility of that To assemble bristle heads individually on a handle.
- P 41 159 43.8 a hand brush as input and a brush head for one adjustable oscillator drive according to Patent No. P 44 023 66.9, consisting of a shaft with shape in continuation of a stem or connecting part, with a push fit the output pin of a drive.
- a bristle-bearing head that is in at the front end divides two parts, into an elastic branching, into two bristle-bearing legs passes over, the bristles of which are cut, rounded and smoothed in parallel with the thighs.
- These brush bodies are made by healing air and ultrasound or chemical means on two Folded axles softened to simultaneously fold both legs in a U-shape allow so that the bristle fields are mirror images of each other, so that it to the horizontal axis of the handle in an inclined position with an application gap, is formed between the bristle fields.
- the object of the proposed invention is to be equipped with Bristle bundles attached to a bristle-bearing stem with a branch attached to one Handle and after all processing of the bristles, using a A softening process in the area of branching can be folded, a second way to show to further cover the spectrum of these double-head brushes.
- a so-called base part which as a complete molded molded part, two bristle-bearing Stems or legs united.
- the resilient legs, the bristles at the front end wear, provided with a stop in the stem area to the U-position of the double head to establish a coincidence of the application angle between the bristles is avoided.
