Description

Body care device

The invention relates to a device for personal care,

comprising a arranged in a handle part drive unit and a releasably connectable to the handle part massage head, which comprises a housing and a trained for skin contact massage element, wherein the handle part has at least one drive element driven by the drive unit.

Modern devices for the human body care, in particular massagers, facial cleaners or hair clippers usually comprise a handle part, which a

Drive unit, such as an electric motor, and a head part, which can be placed on the handle part and at least one application unit, in particular a

Massage unit, a brush unit or a cutting unit has. In the mounted on the handle portion state, the application unit is coupled to the drive unit that the application unit is driven to at least one on the human body for the purpose of personal care

acting, in particular moving element, such as e.g. a massage or cleaning brush or a cutting or

To set the blades of the application unit in motion. The head part is usually releasably connected to the handle part in order to facilitate the cleaning of the application unit and / or to bring either different head parts used.

For example, massage units, cleaning units and cutting units can optionally be connected to the same handle part, so that the number of necessary devices is reduced.

In massage units, a variety of different solutions is known as the trained to touch the skin massage element can be moved. For example, that can entire massage element rotated, moved axially or through

Vibrations are moved.

In the context of the invention, a massage head is understood to mean an application head which can be placed on a handle part and which has a flexible contact with the skin of the user

Having skin contact element whose driven by the drive unit movement causes a spatially and temporally varying action on the skin. The massage element of the massage head can not only perform a massage of the skin and under the skin body area, but instead or additionally fulfill a cleaning function, for which purpose the massage head as a cleaning head, possibly together with a cleaning agent used, and. having a cleaning brush.

From the prior art devices of the type mentioned are known in which the movement of the drive elements is transmitted directly to the massage or cleaning element, so that the massage or cleaning element rotates itself and thus provides the desired effect on the skin. Both

Devices of this type, the massage or cleaning element to a defined, i. uniform and in the case of an oscillation regularly repeating, driven movement, so set at the contact between the moving massage element and the skin of the user defined states. However, there is a risk that the user's skin too

Vibrations is stimulated, which are perceived as unpleasant and which let the desired massage effect in the background.

It is therefore an object of the invention to improve a device of the type mentioned in that the massage or Cleaning effect is improved. Furthermore, the invention aims to drive the massage head with oscillating drive elements, in particular with oscillating drive elements, as they are found in handle parts of shaving or hair cutting apparatus.

To achieve this object, the invention consists in a device of the type mentioned essentially in that the massage head at least one of the particular translationally oscillating drive element in the connected state

having drivable transmission element, which is so

is arranged to provide a movement in the driven state, which has a with the housing and the

Massage element connected receiving element on the

Massage element is transmitted. The receiving element serves on the one hand as a support for the massage element and on the other hand connected to the housing of the massage head.

This allows the movement of the transmission element on the housing, from the housing to the receiving element and from

Receiving element are transmitted to the massage element. The motion transfer is therefore not directly via a

Clutch between the drive element and the massage element, but indirectly via the components of the massage head, in particular via the housing, with which the massage element or the receiving element of the massage element is connected.

The indirect drive of the massage element makes it possible to superimpose different movement processes. The oscillating movement of the transmission element driven by the at least one drive element of the handle part causes vibrations with a different frequency or with a phase shift and possibly resonant vibrations when transmitted to the housing of the massage head in the housing. which superimpose the oscillating motion. Possibly. finds another superposition due to the resonant vibrations of the

Pickup element instead. Altogether, a chaotic movement pattern of the massage element, which has a particularly effective massage or massage effect, is created in this way

Cleaning effect has the consequence.

The transmission element may in this case preferably have the function of a vibrating mass, which of the at least one drive element of the handle part in motion or

Oscillation is shifted. The transmission element is preferably not in direct contact with the receiving element or the massage element, so that the desired indirect

Motion transmission is guaranteed.

The use of the transmission element as a vibrating or vibrating mass allows in a simple manner, the translationally oscillating drive movement of the

Drive element for generating a vibration of the

Use massage element.

It is preferably provided that two drive elements are provided which can be driven to opposite translational movement, wherein the movement paths of the drive elements preferably parallel to each other. Such drive elements are particularly well suited because the movement provided by these drive elements can be easily and efficiently converted into movement of the transfer element. Through the use of more than one drive element and the robustness of the motion transmission and the number of

Increased possibilities in the formation of the motion transmission. The opposite movement of the drive elements also leads to a mass balance, so that the smoothness increases is reduced and caused by the inertia deflections of the handle part.

Furthermore, it is preferably provided that the at least one drive element is an elongated drive pin whose

Longitudinal extent runs parallel to the handle part axis. A drive element of this type can be used well because it has a good connectability with the transmission element. The transmission element in this case has, for example, a guide in which the drive element is arranged in the connected state. The drive pin preferably has a round cross-section.

In order to prevent the movement occurring in the massage head for the massage element is introduced into the handle part, it is preferably provided that between the handle part and the

Massage head is arranged a damping element. This avoids that the handle is moved undesirable and thus the holding comfort of the device is reduced. The

Damping element can be fixed to the handle part or the

Transfer element stores. The axis is in this case preferably arranged substantially parallel to the handle part axis. Furthermore, the axle can be mounted in the receiving element, whereby the transmission of the movement is improved on the receiving element. In a preferred embodiment, the housing of the massage head forms a frame, which forms in the middle the axis for the transmission element, which is connected to the frame via a web. In the connected state, the at least one drive element protrudes through the frame and is engaged with the held by the axis

Transmission element. This training is

Receptacle cap-shaped disposed over the transmission element and the frame formed by the housing

supported.

Furthermore, it is preferably provided that the receiving element releasably, preferably with latching connections, with the housing

connected is. This makes the receiving element easy

be replaced and replaced by another receiving element, eg. With another massage element. A simple type of releasable attachment is provided by a latching connection, so that the receiving element simple and especially without the help of tools or others

Tools can be detached from the housing or connected to the housing. The connection of the receiving element with the

Housing is designed as a substantially rigid connection, so that the vibrations of the housing can be passed to the receiving element or the massage element.

In order to exchange the massage element easily and quickly, it is preferably provided that the massage element is releasably connected to the receiving element. An exchange of

Massage element may, for example, be necessary if the massage element is already worn and no longer the desired

Providing massage effect. Also the exchange of one

Massage element against another type of massage element is possible. The detachable connection may, for example, be designed as a latching connection. Alternatively or additionally, the

Receiving element have a groove into which the massage element can engage. The massage element is preferably made of a flexible material, whereby the connection with the

Recording element can be facilitated.

However, the massage element and the receiving element need not necessarily be designed as separate or detachable from each other components, but may also be integrally formed with each other. The receiving element is to be regarded as that part which contains the massage elements, such as e.g. wearing massage nubs or bristles.

Particularly preferably, it is provided that the movement is a vibration. In this case, the transmission element is moved so that it exerts on the housing a vibrating movement, which subsequently on the receiving element and the massage element is transmitted. Such a vibration provides a pleasant massage effect.
