Description

Hand device for combined facial care

The present invention relates to a hand-held device for combined facial care.

Recently, various, suitable for home use hand-held devices for the mechanical treatment of facial skin have become known. Furthermore, devices for the separate steaming of facial skin are known.

For example, from DE 42 43 876 A1, a device for skin treatment is known, which has a treatment button, through which a suction pressure field can be caused on a skin area, wherein the treatment button is provided with a heating and / or cooling device through which the Treatment button can be heated and / or cooled. In addition, DE 32 1 1 767 C2, DE 31 07 787 A1 and WO 94/041 16 A1 describe hand-held devices for steam treatment and for the mechanical treatment of facial skin.

As far as devices available in the state of the art are operated via mains current, they have the disadvantage that they are generally unwieldy for the user. If such a device is firmly connected to the power supply in order to ensure a corresponding energy supply, the possibilities of movement of the user during use are considerably limited.

A professional skin cleansing usually includes several steps, namely the removal of cosmetic residues such as make-up; opening the pores, which is usually done by warm steam; the mechanical abrasion of dead cell layers; the disinfection and the application of a nourishing cream.

In order to be able to carry out these steps professionally and within a reasonable amount of time at home, a user requires corresponding electrically operated handsets. The user has to perform several steps with different devices. This has the disadvantage for him that a plurality of devices are to procure. If it has several devices that can be operated advantageously via rechargeable batteries with associated charging stations, there is a risk that a device may be inadvertently placed in a wrong charging station and thereby damaged.

Furthermore, it could be observed that, in particular, devices operated in battery mode for the separate steaming of facial skin have a very high energy consumption and, consequently, an unpleasantly short operating time.

On this basis, the present invention has the object to provide a comparison with the prior art more economical hand-held facial care device.

This object is achieved by a hand-held device for combined facial care with the features according to claim 1. Advantageous embodiments and further developments of the invention, which can be used individually or in combination with each other, are the subject of the dependent claims.

The hand-held device according to the invention for combined facial care is characterized by the fact that it comprises means for the mechanical treatment of facial skin as well as for

Steam treatment includes a facial skin. This is compared to the state of Technology achieved a significant improvement in ease of use. In particular, a user saves space and costs through the combined device. At the same time, the cosmetic treatment is facilitated, since he can now perform several treatment steps with one device.

It has proven to be advantageous if the handset has at least one, preferably replaceable, brush or a set of brushes. This has the advantage that a brush can adapt particularly well to the skin structure and, moreover, in the case of mechanical wear of the brush, only this and not the entire device has to be replaced.

For the treatment of facial skin, it is also advantageous if the means for mechanical treatment performs vibrating and / or oscillating movements. Through these movements, a high efficiency of skin treatment at the same time subjectively pleasant feeling of a user is possible.

In a preferred embodiment, the means for mechanical treatment are electrically and / or electromagnetically driven.

It is also advantageous if an electric motor and / or an electromagnet are used to form a rotating or linear movement.

In a preferred embodiment, the vibratory movement takes place at a frequency of 150 to 250 Hz, preferably 180 to 220 Hz, and most preferably 200 Hz. With a vibrating movement of these frequency / frequency ranges cosmetic residues of different composition / origin and possibly dead Cell layers are removed very gently. It has proven to be advantageous if different brushes are used for different skin types and skin age. It is thus an advantage to use brushes with a more cleansing effect for the care of young skin. Due to the higher cell division rate and the higher water content of younger skin such brushes are particularly advantageous to remove the impurities, both endogenous impurities such. Acne as well as exogenous contaminants such as dust particles or other particles transmitted through the air. With older skin, cell division rate as well as water content are lower. Here, such brushes are particularly beneficial to maintain the skin and support the renewal, z. B. by a light massage, which stimulates blood circulation. In general, the brushes with more cleansing effect will be harder and rougher than those with more nourishing effect.

In a preferred embodiment, the handset comprises a liquid tank and a liquid atomization unit. To facilitate the operation of the liquid tank can be designed to be removable. This facilitates the filling and emptying of older liquids.

Advantageously, the unit for atomizing the liquid to an electronically controllable piezoelectric element for ultrasonic atomization, which produces steam with a drop size of preferably 5 to 15 .mu.m, preferably 7 to 12 .mu.m, and particularly preferably 10 microns. Steam with such a drop size has proven to be particularly advantageous when it comes to open pores of the skin. It is advantageous if a liquid is supplied by means of steam of 3 to 10 ml / min, preferably 4 to 7 ml / min and more preferably 5 ml / min. It has also proven to be advantageous if the steam has a temperature of 35 to 55 ° C, preferably 30 to 50 ° C, and particularly preferably 38 ° C. The temperature should be slightly above the natural skin temperature to increase the pore opening, but not too high to avoid skin irritation.

In a preferred embodiment, the unit for atomization is designed such that in each case only a defined area of the facial skin can be acted upon with liquid and / or steam. Advantageously, this defined surface is circular and has a diameter of 2 to 6 mm, preferably 3 to 5 mm, and particularly preferably 4 mm. This embodiment has the advantage that it requires only a relatively small energy supply for the supply of the surface with steam. By gentle circles, it is equally easy to define and comfortably maintain a facial surface of about 30 mm in diameter.

In a preferred embodiment, the voltage supply of the means for mechanical treatment and / or the means for steam treatment via a mains supply and / or a battery supply. It is advantageous if the handset has at least one rechargeable battery and at least one charging station, with which the battery can be charged.

It has proved to be particularly advantageous if the heating device is such that heating of the liquid takes place only when the hand-held device is connected to the charging station. Heating the liquid requires a lot of energy. If the handset is designed so that the heating of the liquid takes place only when the handset is connected to the charging station, the operating time in battery operation can be extended considerably. It is advantageous in this case if the unit for atomizing the liquid is such that the power supply of this unit takes place via battery current and / or mains current. For example, if the heating element is operated only when the handset is connected to the charging station, and the unit for atomizing the liquid operated even when the handset is not connected to the charging station, so in battery operation, a considerably prolonged duration of the steam treatment can be achieved become.

It has been shown that it is advantageous to provide a temperature sensor which, upon reaching a - preferably adjustable temperature - turns off the heating element and / or prevents the controllability of the piezoelectric element. If the attainment of this preferably adjustable temperature is communicated to the user by means of an optical or acoustic signal, then he can be sure that he will then find an optimum temperature for the steam treatment.

Finally, in a preferred embodiment, the handset has various control programs, which are preferably adjustable via a display. Thus, e.g. different programs for different skin types or for different cleaning or care programs are created, which can be accessed by the user as needed.

The device according to the invention for combined facial care also facilitates the usual treatment steps of a professional facial care independently of a voltage fed via landline and thus allows a comfortable and contemporary beauty care. Further advantages and embodiments of the invention will be explained below with reference to various embodiments, to which the present invention is not limited, and with reference to the accompanying drawings.
