The object of the present invention is to provide a cosmetic brush, which achieves an improved cleaning effect and is preferably produced particularly inexpensively.

This object is achieved by a cosmetic brush which has the features encompassed by claim 1. Further advantageous embodiments are described by the subclaims.

description

To achieve the object mentioned, the invention proposes a cosmetic brush for cosmetic skin care and / or skin cleansing, in particular for cosmetic facial care and / or facial cleansing. The cosmetic brush comprises a base part with at least one brush holder, via which at least one brush attachment is interchangeably arranged on the base part, and with at least one ultrasonic generator arranged on the base part.

The at least one brush attachment is at least partially rotatably mounted on the base, so that the at least one brush attachment rotates about the at least one ultrasonic generator and performs an oscillating movement. As a result, the cleaning effect of the ultrasonic waves can be additionally supported.

The at least partial rotation of the at least one brush attachment can be effected by an actuator, which actuator is preferably formed by an electric motor or the like.

The at least one brush attachment can be selected from a plurality of brush attachments, which are each formed differently. In particular, the brush attachments may differ in size. It may be provided that the size, but in particular the diameter, of the at least one brush attachment is greater, equal or smaller than the base part, in particular its diameter.

In addition, the at least one brush attachment with a plurality of bristles arranged in bundles can be equipped in a specific arrangement and with defined properties. Thus, the brush attachments can also each differ in the type and / or arrangement and / or number and / or orientation of the bristles, etc., so as to cover different application. The bristle bundles may be arranged, for example, circular and / or square and / or rectangular and / or triangular on the brush attachment. A combination of the different arrangements of the bristles or bundles of bristles would also be conceivable. In addition, the brush attachments may for example be equipped with bristles of different hardness to achieve a different strong cleaning and / or massage effects. The respective brush attachment is selected depending on the desired application. A soft brush attachment is suitable for facial cleansing, a slightly harder one is used for exfoliation, and special attachments are used to massage care creams into the skin.

A bundle of bristles or a bundle of bristles may be a plurality of individual bristles which are arranged closely and / or closely adjacent to one another and thus form a bundle. Preferably, a plurality of bundles, in particular a plurality of bundles, are provided on the at least one brush attachment.

The at least one ultrasonic generator can form frequencies that are above the audible range of the human ear. Accordingly, the at least one ultrasonic generator can generate ultrasonic waves in a frequency range between 5 kHz to about 10 MHz, in particular between 2 MHz and about 4 MHz. The power used is in the range of approx. 10 watts approx. 20 KW.

The at least one ultrasonic generator may extend at least substantially perpendicularly from the base part. Preferably, the at least one ultrasonic generator can be arranged in the center or in the center of the base part. As a rule, the at least one ultrasonic generator can be arranged fixedly on the base part. In addition and / or optionally, the at least one ultrasound generator can also be arranged rotatably on the base part of the cosmetic brushes.

Depending on the embodiment of the at least one brush attachment, the bristles or bristle bundles arranged in bundles may protrude beyond the at least one ultrasound generator or terminate with the at least one ultrasound generator, the first embodiment being the preferred variant. This has the advantage that the bristles projecting beyond the ultrasound generator reduce a possible risk of injury by the at least one ultrasound generator and also prevent unpleasant pressure points and / or friction, which may possibly be caused by an ultrasound generator that is too long.

By means of the at least one ultrasonic generator, it is possible to generate a vibration of the bristles of the brush attachments with a corresponding frequency. The ultrasonic waves can act mechanically and thermally on the body parts treated with the cosmetic brush. The mechanical effect is a vibration effect. The sound pressure causes strong compression and expansion in the surrounding tissue, which corresponds to the effect of a powerful massage or connective tissue massage.

The thermal effect is created by the sound absorption of the body's own tissue and sets cells in vibration, which is equivalent to a kind of deep massage. The ultrasound waves cause improved cell metabolism and increased blood flow, resulting in permanent improvement of the skin structure of the treated body parts, for example, facial parts.

According to one embodiment of the invention, it is provided that the rotation of the brush attachment and / or the generation of ultrasonic waves of the at least one ultrasound generator does not take place automatically when the cosmetic brush is switched on. Instead, the base part of the cosmetic brush may comprise one or more operating elements by means of which the rotation of the at least one brush attachment and / or the ultrasound waves of the at least one ultrasound generator can be switched on and / or off. Preferably, at least two operating elements may be provided on the base part, one being designed to connect and / or disconnect the rotation of the at least one brush attachment and one for connecting and / or disconnecting the at least one ultrasonic generator.

The user can thus selectively select via the one or more controls whether he wants to use the cosmetic brush with or without ultrasound and with or without rotation of the brush attachment. When using the cosmetic brush without rotation of the brush attachment, the user can if necessary even carry out a circular movement of the cosmetic brush to perform the skin care and / or skin cleansing.

About the one or more controls, the rotational speed of the at least one brush attachment can be selected and / or adjusted. In this case, at least two selectable or defined rotational speeds can be predetermined. Optionally, the reaction rate can also be selected and set from a predetermined rotational speed range. A slower rotational speed of the at least one brush attachment may provide a gentler and milder care and cleansing of the treated skin and / or face, while a higher rotational speed may result in deeper and more intensive care and cleansing of the treated skin and / or face.

In addition, the frequency of the ultrasound generated by the at least one ultrasound generator can be selected and set by the one or more control elements. In this case, at least two selectable or defined predetermined frequencies can be provided. Alternatively, any frequency can be selected and set from a given frequency range.

By the movements of the cosmetic brush, in particular by the vibrations generated by the ultrasound and optionally the rotating or oscillating movement of the at least one brush attachment excess dander can be removed. In addition, the use of the cosmetic brush contributes to the fact that the skin is better supplied with blood. This will make the skin look smoother and gets a better color. The skin looks altogether younger and fresher. The ultrasonic waves will also reduce pores and eliminate small wrinkles.

The at least one brush attachment may comprise a bore which is formed corresponding to the circumference of the at least one ultrasonic generator. The at least one ultrasonic generator can therefore be guided through the bore of the at least one brush attachment. As a result, the at least one brush attachment can be largely aligned and centered with respect to the base part of the cosmetic brush. Preferably, the bore can be arranged in the center or in the middle of the at least one brush attachment.

The respective brush attachment can, for example, be exchangeably fastened to the at least one brush holder via a snap or latching connection or via a screw connection or the like.

According to one embodiment of the invention, the at least one brush holder can be formed by latching noses or by pins or by an external thread or the like. The at least one brush attachment can have a corresponding receiving area corresponding to the brush holder. The receiving area may be formed by recesses, grooves, slots, internal threads or the like. Preferably, two brush receptacles may be provided, whereby a secure mounting of the at least one brush attachment on the base of the brush is possible.

According to a further embodiment of the invention, the at least one brush attachment may have at least one fastening element on the rear side, which may be in the form of an external thread, bolt or the like. The at least one brush holder can form a corresponding receiving region for the at least one fastening element. The receiving area may be formed by recesses, grooves, slots internal thread or the like. Preferably, at least two fastening elements can be provided in order to securely fasten the at least one brush attachment to the base part.

The base of the cosmetic brush may be formed of a plastic or a metal or the like. The selected material should have a certain resistance and robustness in order to achieve the longest possible life of the cosmetic brush.

The base part of the cosmetic brush may form a hollow part, which may be formed in one piece, but preferably in two parts. In the two-part embodiment, the base part comprises two housing halves, which can be brought together and / or joined together by a plug connection or the like.

The hollow part may have a cavity within which, for example, the actuator and / or electronics for the at least one brush attachment, electronics for the at least one ultrasonic generator and / or the one or more operating elements or the like can be received and arranged. In addition, fixing elements can be provided in the cavity, by means of which the actuator and / or the electronics can be at least partially fastened. This is intended to prevent and prevent unwanted slippage and / or movement of the elements arranged in the hollow part or in the cavity.

In addition, the base part of the cosmetic brush may have a grip area. The grip region may be formed by the same material as the base part or by another material with particularly good grip and anti-slip strength, such as a rubber-like material.

In addition, the cosmetic brush may be associated with a holder, which is designed to receive the base part for stopping the cosmetic brush. The receptacle may be formed corresponding to the base part, in particular to the handle part of the cosmetic brush.
