description

The object of the present invention is to provide a cosmetic brush which achieves an improved cleaning effect and can be used flexibly.

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

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 and an ultrasonic generator. Furthermore, the cosmetic brush has at least one receptacle via which at least one ultrasound head can be interchangeably arranged on the ultrasound generator and on the base part and / or assigned to it.

It is provided here that the user can select from a plurality of ultrasound heads depending on the desired cosmetic application. The different ultrasonic heads differ, for example, in a diameter of an outer contact surface. The diameter may be larger, equal to or smaller than a diameter of the base part. For a two-dimensional application, for example, an ultrasound head with a contact surface with a large diameter can be selected. For a targeted local application, however, an ultrasound head with a small diameter may be advantageous.

It is also possible that the ultrasonic generator generated ultrasonic waves in different frequency ranges. Preferably, frequencies are used 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 ranges from about 10 watts to about 20 kilowatts.

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. The respective selected ultrasound head is in particular attached to the ultrasound generator. In addition and / or optionally, the at least one ultrasound head can also be arranged to be rotatable on the ultrasound generator and / or on the base part of the cosmetic brush.

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 an improved cell metabolism and increased blood flow, resulting in lasting Improvement of the skin structure of the treated body parts, for example facial parts, leads.

According to one embodiment of the invention, it is provided that the generation of ultrasonic waves of the at least one ultrasonic 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 first operating elements by means of which the ultrasonic waves of the at least one ultrasonic generator can be switched on and / or off.

For example, the frequency of the ultrasound generated by the at least one ultrasound generator can be selected and / or adjusted by the one or more first control elements. In this case, at least two selectable or defined predetermined frequencies can be provided. Optionally, an arbitrary frequency can also be selected from a predetermined frequency range and in particular continuously adjusted.

Excess dandruff can be removed from the vibrations generated by the ultrasound, the skin is better supplied with blood, which makes the skin smoother and gives it a better color, making the skin look younger and fresher overall. In addition, pores will shrink and small wrinkles will be eliminated.

The respective ultrasound head can, for example, be fastened exchangeably via a snap or latching connection or via a screw connection or the like on the at least one receptacle on the ultrasound generator and / or on the base part of the cosmetic brush. According to one embodiment of the invention, the at least one receptacle can be formed by latching noses or by pins or by an external thread or the like. The at least one ultrasound head can have a corresponding receiving area corresponding to the receptacle. The receiving area may be formed by recesses, grooves, slots, internal threads or the like. Preferably, two receptacles may be provided, whereby a secure mounting of the at least one ultrasonic head on the ultrasonic generator and / or on the base of the brush is possible.

According to a further embodiment of the invention, the at least one ultrasound head can have at least one fastening element on the rear side, which can be designed in the form of an external thread, bolt or the like. The at least one receptacle can form a corresponding receiving area 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 ultrasound head to the ultrasound generator and / or to the base part.

Furthermore, it can be provided that at least one embodiment of an ultrasound head is designed such that additionally a brush attachment can be interchangeably arranged on the base part and / or on the ultrasound generator.

Preferably, the at least one additionally attachable brush attachment is at least partially rotatably attached to the base and / or the ultrasonic generator, in particular such that the brush attachment rotates about the at least one ultrasonic generator and / or the ultrasound head 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.

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

By the at least one ultrasonic generator and / or ultrasound head, a vibration of the bristles of the additional brush attachment can be generated with a corresponding frequency, which additionally act mechanically on the treated body parts.

According to one embodiment of the invention, it is provided that the rotation of the brush attachment 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 second operating elements by means of which the rotation of the at least one brush attachment can be switched on and / or off. About the one or more second 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.

Preferably, at least two controls may be provided on the base, in particular a first control element for connecting and / or disconnecting the at least one ultrasonic generator and a second control element for switching on and / or off the rotation of the brush attachment.

The user can thus selectively select via the one or more first and second controls, if 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 even perform a circular movement of the cosmetic brush if necessary, to perform the skin care and / or skin cleansing.

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 get a better color. The skin looks altogether younger and fresher. The ultrasonic waves will also reduce pores and eliminate small wrinkles.

The brush attachment may comprise a bore which corresponds to the circumference of the at least one embodiment of an ultrasound head or which is formed corresponding to the circumference of the ultrasound generator. The at least one ultrasonic generator and / or ultrasound head 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 brush attachment.

The brush attachment can be fastened interchangeably, for example, via a snap-fit or latching connection or via a screw connection or the like to a suitable receptacle on the base part of the cosmetic brush and / or on the ultrasound head and / or on the ultrasound generator. Preferably, the at least one brush holder is provided with correspondingly formed locking lugs or pins or an external thread or the like.
