Description

Body care device

The invention relates to a device for personal care, which has a hand-held device and an adapter connecting the hand-held device with a brush head for the purpose of forming a face brush or massage brush.

Such personal care devices are designed as a purely manually operable devices on the one hand, but is also a training with an electric drive to move the brush head relative to the handset.

Depending on the specific design training different forms of movement can be realized. Typically, this is, for example, a vibration or a rotational movement. Optionally, however, other movements can be realized. According to also already known construction forms, the brush head is exchangeably connected to the handset using an adapter.

A problem with the use of known such devices is that often the cleaning effect to be generated and / or a massaging effect depends on a constructive adjustment of the brush head on the handset and a correct connection of the brush head with an optionally used drive. A combination of not optimally matched parts often leads to a deteriorated effect.

Furthermore, known such devices have an insufficient cleaning effect.

Object of the present invention is to support a combination of optimally matched components with each other and to prevent the use of not optimally matched components either or to complicate possible and to avoid overloading the skin of the user.

This object is achieved by the structure of the handset preferably in conjunction with a novel wiping movement of the brush head.

The task takes the help that the base part has an adapter, and that the adapter has at least one primary part having a corresponding to a arranged on the brush head secondary part training.

A further object of the invention is to construct the base part from a plurality of shells, which optimally make it possible to realize the wiping movement and to guide and seal the axis leading to the adapter through the shell.

A further object of the invention is to drive the face brush or massage brush with a so-called oscillating armature drive with a control program which maximizes the cleaning performance with minimal noise emission. A further object of the invention is to realize a head protection, which allows to protect the brush head and at the same time predefines a defined storage position of the face brush or massage brush.

Another object of the invention is to achieve an improved cleaning performance through the novel construction and brush head movement.

The facial brush or massage brush basically consists of a hand-held device and a brush head.

The handset is externally visible from a front and a rear shell part, which are connected to a cutting seam. In the front shell part different breakthroughs are realized. In the front shell, the charging socket is integrated, this is accessible through the charging socket breakthrough in the housing from outside the housing. The charging socket breakthrough and, of course, the charging socket itself are located at the bottom of the handset, opposite the brush head. In addition, an opening for the on-off switch is introduced in the front shell part. In the head area a breakthrough for the drive shaft is introduced, the drive shaft breakthrough, through which the drive shaft is guided through the housing.

The two shells of the handset are preferably made of hard and soft component. The hard component forms the supporting part of the shells or the housing. The secure hold of the device in the user's hand is ensured by the hard component, further, the support structures inside the housing are also made in hard component, so that the assembled parts are clearly positioned and well fixed. The soft component has other functions. On the outside of the housing or the shells it can be applied for ergonomic purposes, to guarantee an even safer hold. Functionally for the device, it can be introduced, for example, for sealing purposes. In the present case, the on-off switch opening is closed with a layer or a membrane made of soft component. The soft component is designed so that it is flexible and allows actuation of the lying inside the housing on-off switch or pushbutton. By this arrangement it is achieved that the operation is possible on the one hand and on the other hand, that the interior is still tightly sealed. The drive axle aperture is also closed with a soft component. It is so that the drive axle is passed through a sealing element made of soft component. The sealing element thus seals directly against the drive axle. It also seals by the direct concerns on the shell part. By this configuration, on the one hand ensures the sealing of the interior of the housing and on the other hand, the possibility of movement of the drive axle is given.

The sealing element in the region of the drive axle breakthrough can either be injection-molded or mounted. The sealing element in the region of the drive axle breakthrough is preferably mounted, since it preferably consists of silicone, which is processed in a method other than the injection molding process. The sealing element has a bellows-like shape so that the seal is ensured even when the axis is deflected.

The switch parts are manufactured by injection molding. In particular, the front shell part uses a so-called multi-component injection molding process. In the first step, the hard component is injection-molded, onto which structure the soft component is injected. For parts made of only one component, such as the rear shell part, a one-component injection molding process is used.

In the head area of the handset, the brush head recess is inserted in the front switching part. In the recess of the drive axle perforation is arranged, from which the drive axle protrudes, but which is not visible in the finished handset, since the adapter is plugged onto the drive axle and thus covers or protects the drive axle. Finally, the brush head can be plugged onto the adapter so that it is at least partially inserted in the brush head recess. Laterally, that is left and right at the edge of the depression, handle recesses are created. These are to ensure that the brush head can be better mounted on the adapter and disassembled. Due to the fact that the brush head lies in the brush head recess, it can otherwise only be grasped poorly. Preferably, two handle recesses are realized and these are preferably offset by 180 °. But it is also conceivable to introduce further handle recesses, but preferably always so that two 180 ° are arranged opposite to each other. With regard to the position of the handle recesses, it should be mentioned that these are preferably not at the same height as the drive axle, but somewhat offset in the direction of the upper portion.

The brush head recess has a diameter of 30 mm to 65 mm, preferably 40 mm to 55 mm. The depth (in the upper area) relative to the outer skin of the housing is 3 mm to 8 mm, preferably 4.5 mm to 6.5 mm viewed along the longitudinal axis. The depth at the rear end is preferably about 0.5 mm less than at the front end. The depth is laterally 2 mm to 5 mm, preferably 3 mm to 4 mm larger than the depth in the upper area. This is due to the wiping movement of the brush head. The length of the handle recesses is between 10 mm and 20 mm, preferably between 12 mm and 18 mm.

The facial brush or massage brush is equipped with a rechargeable energy storage, a battery. The battery can be charged by a power supply, which is connected via a cable and a plug, which is plugged into the charging socket. The multiple use is supported. A charge by induction or removable batteries are also conceivable.

An essential aspect of the present invention relates to the interaction between the brush head and the adapter. The inventive solution, the total weight of the brush head and adapter can be significantly reduced. The adapter is in this case in particular the part on the device to which the brush head is attached. The inventive design of the interface from the handset to the brush head is realized from the structurally matched adapter with primary part of the interface and the corresponding attached to the brush head secondary part of the interface. The design of the respective parts supports the functional allocation of the individual components.

In the application, elements of the secondary part of the interface (at the brush head) reach over or into elements of the primary part of the interface (on the adapter). Through this direct coupling a mechanically durable construction is achieved. Preferably, the elements of the secondary part engage laterally over the adapter or the primary part of the interface and certain other elements of the secondary part engage in elements of the adapter or of the primary part of the interface.

A possible confusion security or prevention of incorrectly orienting mounting of the brush head on the adapter can be achieved by certain elements an interface by corresponding arrangement (counter profile) and clear orientation cause a clear assembly. According to a preferred embodiment, an assembly of components that are not optimally matched to one another is mechanically prevented by, for example, the fact that projections and depressions of the components to be assembled do not fit together in the case of incorrect or poorly shaped components. But there are also other concretely matched corresponding shapes conceivable.

The adapter is mounted on the drive axle. The drive axle is driven by the drive, which is described elsewhere, and directs the movement of the motor to the opposite end of the drive axle to the motor. The drive axle is preferably made of a metal and, as already described, is guided through a seal in the drive axle aperture. The drive axle is connected to the adapter. For this purpose, the drive axle can be provided with connecting means, for example it can be roughened and the adapter provided in the region of the interface with an undersize, so that a secure fastening is possible. Further, of course, other types of connections such as screwing, gluing or others may be used. The Connecting means preferably act to train and rotate to fix the adapter in its intended position.

The adapter is preferably designed as an element with a round outer contour. As a result, technical, aesthetic and application-ergonomic advantages can be combined. The round outer contour has the advantage that even bristle heads can be realized, which need not be oriented to the adapter to be placed. The corresponding geometries, which guarantee the orientation, are omitted at least on the head side.

Looking at the side wall of the adapter, it is composed of a cylindrical surface and a bead. Both are formed over 360 ° around the adapter and form essential elements of the primary part of the interface (on the adapter). In the mounted state of the brush head snap elements are driven over the bead and the transmission elements abut the cylindrical surface.

As a further element of the interface geometry on the adapter, orientation recesses are created in the adapter. These are preferably directly adjacent to the cylindrical surface, i. arranged openly against them.

The bead is measured parallel to the drive axis 1.2 mm to 3.5 mm, preferably 1.8 mm to 2.8 mm long. It has a height, measured perpendicular to the drive axis, from 0.2 mm to 0.6 mm, preferably from 0.3 mm to 0.5 mm. The bead has a proportion of 25% to 60%, preferably 35% to 50%, relative to the total height of the side wall of the adapter.

The geometry of the side wall of the adapter is matched to the snap elements and transmission elements. The snap elements grip over the bead and the transmission elements lie directly below the bead. The bead is quasi clamped between the snap elements and the transmission elements. The bead has the structure described below from the cylindrical surface. Three essential elements form the geometry. A first rising ramp, an area and a second sloping ramp.

The first rising ramp is designed with respect to the cylindrical surface at an angle of 20 ° to 50 °, preferably from 25 ° to 35 °. The length parallel to the drive axis is 0.3 mm to 1.1 mm, preferably 0.5 mm to 0.8 mm. The height difference that is negotiated with the ramp is 0.15 mm to 0.7 mm, preferably 0.25 mm to 0.55 mm.

The flat surface of the bead is parallel to the drive axis and has a length of 0.4 mm to 1.2 mm, preferably from 0.65 mm to 0.95 mm.

The second sloping ramp has an angle of 10 ° to 40 ° relative to the flat surface, preferably 15 ° to 25 °. At a length parallel to the drive axis of 0.5 mm to 1.4 mm, preferably from 0.7 mm to 1.1 mm.

The geometry of the bead is formed in the transverse direction constant, that is, it is formed around the entire adapter circumferentially the same cross section.

The cylindrical surface on the side wall of the adapter has a height of 1.5 mm to 5 mm, preferably 2 mm to 3 mm.

The diameter of the cylindrical surface is from 14 mm to 22 mm, preferably from 17.5 mm to 18.5 mm. The outer diameter of the adapter is thus composed of the diameter of the cylindrical surface plus twice the height of the bead.

The overall height of the side wall of the adapter is 3 mm to 7 mm, preferably from 4 mm to 5.5 mm. Overall, the adapter is higher than the side wall of the adapter, since the central sleeve protrudes beyond this. The front of the adapter is basically designed as a flat surface. The orientation recesses are embedded in it. The Orientierungsausnehmungen are arranged directly so that they open into the side wall of the adapter. The Orientierungsausnehmungen bring the advantage that brush heads can be placed virtually without orientation on the adapter without appropriate orientation elements.

The orientation recesses can be realized in various ways. In the present case, two identical orientation recesses are created. The mutually offset by 180 ° that is symmetrically arranged on the adapter.

The Orientierungsausnehmung has seen from the flat surface of the adapter ago an inlet slope, so that the brush head can be easily mounted and its orientation easily reached.

To achieve a one-to-one positioning of the brush head on the adapter, for example, the number of positions can be adjusted. If only one Orientierungsausnehmung created so the head can be placed only in one direction. Furthermore, however, the geometry of the orientation recesses can also be adapted. If these are not all identical, the brush head must also be set up specifically.

The orientation recesses have a depth of 0.5 mm to 3.5 mm, preferably from 2 mm to 3 mm. The length measured radially to the center of the adapter is on the flat surface of the adapter of 1.5 mm to 5 mm, preferably from 2 mm to 3.5 mm and at the lower end of the recess of 1 mm to 4 mm, preferably from 1.3 mm to 2.5 mm. The width of the orientation recess is virtually tangential to the diameter measured on the flat surface of the adapter of 1 mm to 5 mm, preferably from 2.5 mm to 4 mm and at the lower end of the recess of 0.5 mm to 4 mm, preferably from 1 mm to 2 mm. With regard to the geometry of the rear side of the adapter, preference is given to a cavity or a ribbed structure. The ribs allow weight reduction without losing stability. Preferably, the rib extends from the sleeve to the outer edge. The number of ribs is preferably in a range of 3 to 9.

The height of the rib is preferably in a range from 0.6 mm to 1.2 mm, particularly preferably from 0.8 mm to 1 mm.

The width is preferably in a range from 0.4 mm to 1 mm, particularly preferably from 0.6 mm to 0.8 mm.

The length of the ribs is preferably in a range from 3 mm to 8 mm, particularly preferably from 4.5 mm to 6.5 mm. The length is measured from the central sleeve to the outer edge.

The central sleeve forms this the holding element for the drive axle. The diameter is preferably in a range of 1.5 mm to 5 mm, particularly preferably 2.5 mm to 3.5 mm.

The height is preferably in a range of 1.5 mm to 5 mm, particularly preferably 2.5 mm to 3.5 mm. It is chosen so that it is the highest element of the adapter and determines the overall height quasi.

The wall thickness is preferably in a range of 0.5 mm to 3 mm, particularly preferably in a range of 1 mm to 2 mm.

The material thickness with respect to the outer walls of the adapter is preferably in a range of 0.3 mm to 1.5 mm, more preferably from 0.6 mm to 1.2 mm.

The adapter is preferably made of a hard component, preferably polypropylene (PP) or polyoxymethylene (POM). For the entire movement that is to be implemented by the hand-held device on the brush head, it is centrally important that the distance from the motor axis to the starting point of the brush head is as low as possible and that the weight of the entire moving part is as low as possible. With regard to the adapter, therefore, a small height is preferably realized, achieved a low weight and given a proximity to the axis.

In general, with respect to the weight of the adapter, this is defined without filaments (bristles) and anchors. It is preferably in a range of 0.1 gram to 12 grams, more preferably in a range of 0.3 gram to 0.8 gram. When using polypropylene, a weight of about 0.42 grams can be realized. When using POM, the weight is around 0.64 grams.

The brush head has the secondary part of the interface and the whole structure of bristle holes, which holds the bristle field.

To achieve the said optimized weights, the brush plate has a special construction. The bristle tufts are not anchored in a simple plate, but the plate is provided on the back with a profile in which superfluous material is omitted.

The corresponding profiling on the back ensures that there is no material surplus around the bristle pots. As a result, the bristle pots emerge as truncated cones out of the plane of the plate.

In general, different constructive realizations can be selected with regard to the internal geometry of the bristle holes. For example, in the form of a structure (from outside to inside, that is, from top to bottom) with an inlet, a cylindrical part with broken edges at the end. With regard to the mass, it is possible, for example in the region of the inlet, to realize a diameter at the outlet in a range of 1.5 mm to 3 mm, preferably in a range of 2 mm to 2.5 mm. With regard to the height of the inlet, an area is preferred realized from 0.5 mm to 2 mm, more preferably from 1 mm to 1.5 mm.

With regard to an angle of the inlet is thought to arrange the opening angle symmetrical. This is preferably done in a range of 15 degrees to 40 degrees, more preferably in a range of 20 degrees to 30 degrees.

The diameter at the end of the inlet corresponds to the diameter of the cylindrical part.

With regard to the cylindrical part, a diameter of preferably 1 mm to 2.5 mm, particularly preferably from 1.5 mm to 2 mm is realized.

With regard to the height of the cylindrical part is preferably a realization in a range of 0.5 mm to 2 mm, more preferably in a range of 0.8 mm to 1.4 mm. The end of the cylindrical part is formed as a broken edge.

In general, the height of the cylindrical part can be adjusted to the height of the anchor plate, which anchors the bristle bundles.

With regard to the total depth of the bristle holes, a range of 2 mm to 4 mm is preferably realized, particularly preferably a range of 2.5 mm to 3.5 mm.

The top of the brush head is preferably flat. But it is also possible to provide the top of the brush head with a profile. For example, all bristle bundles of identical length could be anchored and a surface profile would be created.

A height difference that can be realized is preferably from 2 mm to 8 mm, preferably from 2 mm to 5 mm. The height difference can be realized for example in the form of a crowning towards the center or with a wave structure (concentric or linear). The arrangement of the bristle holes on the top of the brush head can take place in different geometrical configurations, for example as a concentric design, preferably as a design without specific direction, for example as circular symmetry.

An inner circle preferably has a diameter of 4 mm to 8 mm, particularly preferably of 5.5 mm to 7.5 mm.

A diameter of the second circle is preferably 10 mm to 18 mm, particularly preferably 12 mm to 16 mm.

A diameter of the circle 3 is preferably 18 mm to 26 mm, preferably 20 mm to 24 mm.

A diameter of the circle 4 is preferably 25 mm to 33 mm, particularly preferably 27 mm to 31 mm.

A diameter of the outer circle is preferably 33 mm to 41 mm, particularly preferably 35 mm to 39 mm.

With regard to the distances of the bristle pots or the bristle holes from center to center, a minimum mass in a radial direction results from the diameter of the circles or their delta.

The bristle holes are preferably synonymous with filaments provided as bristles. Preference is given to filaments having a diameter of 3 mils and a length of 6 mm to 13 mm.

The bristle field can be constructed circular in a variant. This means that the two inner circles have bristles of shorter length than the bristles in the outer three circles. As a result, a depression forms in the center of the bristle field, which can be used, for example, as a dosing indicator for care products which are massaged in. Another possibility for the design of the bristle field is that, for example, the innermost circle and the center are replaced with a care body. This care body is a mounted in the brush head element, which deliberately releases care products. The care body is designed so that it is mounted as a variant fixed to the brush body and in this way applies in parallel as a change indicator for the brush head. Another variant is the possibility of changing the care body. For this, it must be provided with an interface geometry that fits into the interface geometry at the brush head. The interface geometry on the brush head is preferably designed directly on the brush head, alternatively, a mounted part can form the interface. The care body can be provided directly with the interface or be connected via a mounted / molded part with the interface on the brush body. Preferably, the care body is inserted and fixed in the brush head from the rear side of the brush body removed from the device. By mounting the brush head on the device, the care body is additionally secured.

The bristle holes are preferably arranged in bristle pots. These bristle pots define the geometry around the bristle hole. Basically, the bristle pots are arranged in solid material. In the present case, however, weight must be reduced and so it is necessary to at least partially release the bristle pots.

With regard to the bristle pots different variants can be realized. For example, it is possible to arrange individual bristle pots free. According to this embodiment, the bristle pot in this case consists of an inlet and a cylindrical part which is arranged in the solid body. Therein, the actual anchoring of the bristles is provided. The conical part of the bristle hole is imaged 1: 1 against the outside and released. The outer dimension for the height of the release may preferably be in a range of 0.8 mm to 2.2 mm, more preferably in a range of 1.35 mm to 1.6 mm. The wall thickness / material thickness between the bristle hole and the outer surface is from 0.3 mm to 1.5 mm, preferably from 0.5 mm to 1 mm. The material thickness in the region of the bottom is preferably higher than in the region of the cone wall, particularly preferably in one Range of 0.8 mm. The material thickness in the region of the cone wall is preferably 0.7 mm.

Alternatively, it is also possible to arrange the bristle pots only laterally freely. This can be realized, for example, with bristle pots on the edge. The half conical part is integrated in solid material and half the bristle pot is arranged freely.

The spacing of the bristle pits / bristle holes is preferably from 2 mm to 6 mm, and is more preferably from 2.5 mm to 4.5 mm, measured from center to center, wherein the dimension is effectively 3.84 mm on an outer ring and 3.2 mm on an inner ring.

The arrangement of the bristle pots or bristle holes in the circles, as described above can be done regularly. Preferably, an angle between the bristle holes from the center is about 360 degrees, divided by the number of bristle holes on the corresponding circle. In particular, the angle can be between 60 degrees in the innermost ring and 12 degrees in the outermost ring.

With respect to the back of the bristle pots, parts of the bristle pots may be covered with material. For example, this is possible with the only laterally cut bristle pots at the edge of the bristle field for stabilizing the brush head. Furthermore, material can be arranged behind the snap elements in order to support the stability of the brush head and / or a fixation of the snap elements.

In the area of the edge, an external stability can be increased by covering the bristle pots with material. A width in the region of the edge is preferably in a range of 1 mm to 4 mm, particularly preferably 2 mm to 3 mm.

The lateral outer geometry of the brush head consists of two elements. An over-edge and a cylindrical surface that connects directly to the upper edge.

The over edge is located at the upper end of the lateral outer geometry directly on the flat surface of the brush head. He serves the quiver And he is also an aid to the assembly and disassembly of the brush head on the adapter.

The upper edge is preferably a semicircle when viewed in cross-section. The upper end of the upper edge continues tangentially into the flat surface of the brush head.

The upper edge has a height (measured parallel to the drive axis) of 0.3 mm to 0.9 mm, preferably from 0.5 mm to 0.7 mm. The height - measured perpendicular to the drive axis is 0.5 mm to 3 mm, preferably 1 mm to 2 mm.

The cylindrical surface on the lateral outer geometry of the brush head has a height of 1 mm to 4.5 mm, preferably from 1.5 mm to 3.5 mm. The diameter of the cylindrical surface is 30 mm to 60 mm, preferably 37 mm to 47 mm.

The total height of the lateral outer geometry of the brush head is between 2.5 mm to 5 mm, preferably 3.3 mm to 4.3 mm. The length fraction of the upper edge at the total height is between 20% and 50%, preferably between 30% and 40%.

Laterally on the brush head below the upper edge gripping aids can be formed. These are used for better ergonomics when mounting / dismounting the brush head on the handset. They also show the user where the head can be grasped. In the assembled state, these are preferably arranged in the region of the gripping recesses. For this to be possible, the adapter and handset must be precisely aligned when mounting the adapter on the handset.

The outer shape of the brush head is preferably round or n-cornered, approximately round. Of course, many other forms are also possible.

The interface geometry on the brush head, that is to say the secondary part of the interface, is preferably arranged directly behind the bristle pots. The interface on the brush head consists of snap elements, transmission elements and Orientation elements. So that the brush head well on the adapter, that is fixed on the handset.

The snap elements are arranged in a number of 2 to 8 pieces, preferably 3 pieces in the interface. They can also be paired, they cover in any case between 2 and 8 positions around the adapter.

The snap elements are arranged around a center on the brush head, this center is in the mounted state of the brush head concentric with the center of the adapter. The distance from the center is for the snap elements (starting point in the middle of the cross section) of 7 mm to 13 mm preferably 8.5 mm to 11 mm.

The snap element is basically constructed in two parts. It consists of a trunk and a crown. The crown is the element that engages behind the bead of the adapter and forms the actual snapper.

The snap element has a height of 3.5 mm to 7.5 mm, preferably from 4 mm to 6.5 mm. The length of the snap element measured along the radius is 4.5 mm to 7.5 mm, preferably 5.5 mm to 6.5 mm at the attachment point and 3.5 mm to 6.5 mm, preferably 4.5 mm to 5.5 mm at the free end.

The trunk is rectangular in cross-section, the cross-section decreases towards the end, as the inner and outer surfaces (viewed radially) converge towards each other. The height of the trunk is between 1 mm and 5 mm, preferably between 2 mm and 3.5 mm.

From the whole structure, the trunk is inclined to the center of the brush head or the interface. The angle on the outer surface (directed towards the center) is 80 ° to 89 °, preferably 83 ° to 87 °, and on the inner surface 85 ° to 90 °, preferably 87 ° to 90 °, most preferably 90 °. The narrowest point of the cross section is between the stem and the crown of the snap element and is between 0.5 mm and 1.2 mm, preferably 0.7 mm to 1 mm.

The crown is placed on the trunk, the outward geometry of the trunk continues seamlessly in the geometry of the crown.

Directly at the stem follows a geometry with a circle radius, which defines the inner radius of the snapper and is placed directly on the trunk. This inner radius is from 7 mm to 12 mm, preferably from 8 mm to 11 mm. This element has a height of 1 mm to 5 mm, preferably 2 mm to 4 mm. The completion of the crown (at the free end) is formed by an insertion geometry. This has a radius of 0.5 mm to 3 mm, preferably from 1 mm to 2 mm.

The transmission elements are the counterpart to the snap elements in the interface geometry. Between the two element types there is a kind of positive connection under pressure with the adapter. This ensures that the movement is optimally transmitted from the adapter to the brush head. Furthermore, it is avoided that the brush head does not sit completely fixed on the handheld device or adapter and thus generate noise in the application.

The transmission elements are arranged in a number of 2 to 8 pieces, preferably 1 to 3 pieces in the interface. They can also be paired, they cover in any case between 2 and 8 positions around the adapter.

The transmission elements are arranged around a center on the brush head, this center is concentric with the center of the adapter in the mounted state of the brush head. The distance from the center for the transmission elements (starting point in the middle of the cross section) of 7 mm to 11 mm is preferably 8 mm to 10 mm. The transmission element is basically constructed in two parts. It consists of a trunk and a crown. The crown is the element that reaches under the bead.

The transmission element has a height of 1.5 mm to 5 mm, preferably from 2 mm to 3.5 mm. The length of the transmission element measured along the radius is 1.5 mm to 7 mm, preferably from 3 mm to 6 mm at the attachment point and somewhat less at the free end than at the attachment point.

The trunk is rectangular in cross-section, the cross-section decreases towards the end, as the inner and outer surfaces (viewed radially) converge towards each other. The height of the trunk is between 0.8 mm and 2.5 mm, preferably between 1 mm and 1.8 mm.

From the whole structure, the trunk is inclined to the center of the brush head or the interface. The angle on the outer surface (directed towards the center) is 70 ° to 90 °, preferably 80 ° to 90 °, and on the inner surface 90 ° to 105 °, preferably 90 ° to 95 °.

Directly at the stem follows a geometry with a circle radius, which defines the inner radius of the transmission element and is placed directly on the trunk. This inner radius is from 7 mm to 12 mm, preferably from 7.5 mm to 10 mm. This element has a height of 0.75 mm to 3 mm, preferably 1 mm to 2 mm. The completion of the crown (at the free end) is formed by an insertion geometry. This has a radius of 0.5 mm to 3 mm, preferably from 1 mm to 2 mm.

The snap elements and the transmission elements are arranged on the back of the brush head. They are preferably arranged alternately. Opposite the mentioned center of the interface are the two element types arranged opposite each other. The elements are arranged regularly on the circle over 360 °, that is, for example, that with three snap elements and three transmission elements between the individual elements, an angle of 60 ° relative to the center is formed.

In conjunction with the adapter, the brush head has a pull-off force of 8 N to 30 N, preferably from 10 N to 20 N. This is achieved by the interaction of adapter, snap and transmission elements.

The total weight, which is eminently important for the transmission of motion as well as the deflection, is between 3 grams to 12 grams, preferably 3.5 grams to 8 grams. Naturally, the shaped volume as well as the materials used play a central role.

The total height of adapter and mounted brush head is from 5.5 mm to 12.5 mm, preferably from 7.5 mm to 10 mm.

The support of the snap element on the adapter, measured parallel to the drive axis, is 0.2 mm to 4 mm, preferably 0.2 mm to 1.5 mm.

By resting the bead of the adapter on the transmission elements is further achieved that the entire geometry does not tilt, because a support is formed.

The total height of the brush head including the interface geometry consisting of snap elements and transmission elements is between 7 mm and 13 mm preferably between 8.5 mm and 11 mm.

The diameter of the brush head is 25 mm to 60 mm, preferably 38 mm to 48 mm.

The sprue may for optical reasons preferably be arranged on the back. Preferably, a position of the sprue is located at the edge, but alternatively it can also be arranged inside in the middle of the interface. Other variants exist in an array just behind the brush field and an array just behind the bristle hole.

The weight of the brush head without filaments (bristles) and anchors is from 3 grams to 10 grams, preferably from 3.5 grams to 6.5 grams. In particular, when using polypropylene for the brush head about 3.87 grams and when using polyoxymethylene 5.98 grams.

Due to the configuration of the interface between the primary part and the secondary part, the orientation element is introduced on the brush head into the orientation recess on the adapter. This makes it possible to put the brush head in the present case only in two possible positions on the handset. Depending on the number and arrangement of the elements can be achieved that the brush head can be placed only in one orientation on the handset.

According to other alternative embodiments, the structural coordination of the parts of the interface to one another can also be effected, for example, by magnetic elements or comparable active elements.

A preferred material for the brush head is a hard material, particularly preferred is a polypropylene (PP) with an E-modulus of 1000 N / mm2 to 2400 N / mm2, more preferably between 1300 N / mm2 and 1800 N / mm2. Alternatively, polypropylene (PP) may be used with a reinforcing material (e.g., glass fibers) or polyoxymethylene (POM).

The adapter is preferably made of a polyoxymethylene (POM), the density of the material and the abrasion resistance (the adapter is located on the handset and is repeatedly burdened with new brush heads) are the reasons.

According to another aspect of the invention, good efficiency is achieved by optimizing the distance between the axis of rotation formed by the motor axis and the brush plate or surface of the brush. The distance in question is limited to a maximum value so that the are limited to the resulting lever acting motor forces. If the hand-held device is considered with the brush head mounted, the distance from the motor axis to the point of attachment of the brush head is preferably in a range of 10 mm to 14 mm, particularly preferably in a range of 11 mm to 13 mm. The distance of the motor axis to the bristle end is preferably 20 mm to 30 mm, particularly preferably from 22 mm to 25 mm.

A simplified use is achieved in that a motor is arranged in the housing.

For cosmetic application, it proves to be particularly advantageous that the motor is designed as an electric motor.

Simple handling is also supported by the fact that the motor is coupled to the power supply with a battery or a rechargeable battery.

The motor which dictates the movement of the personal care appliance is preferably an oscillating drive, for example in the form of a vibration armature drive or a mechanical drive. Preferably, a vibration armature drive is used.

Inside the handset, the power supply, motor, on-off switch and controller are housed between the front and rear shells.

The module has at the rear end of the power supply, which is preferably realized in the form of a rechargeable battery, which can be charged via the charging socket. Alternatively, replaceable batteries can be provided. Subsequently, a rocking armature motor is mounted, which has arranged the motor axis in the longitudinal direction of the hand-held device. Above these two elements, the so-called printed circuit board is mounted, which includes the electrical connections, the control and the on-off switch.

The motor is designed to produce a reversing or oscillating back-and-forth motion. Movement makes. The motor axis is L-shaped connected to the drive axle. In this way, the drive shaft also moves reversing back and forth. In the end, the brush head is moved in the same way, resulting in a wiping back and forth movement.

The movement happens in a plane which has the motor axis as normal. The brush head is moved on a circular arc with center motor axis. Strictly speaking, when viewed perpendicularly to the handpiece, there is also a certain up-and-down movement, since the brush head moves on a circular arc, different bristle spacings / bristle heights positions are achieved.

The starting point of the movement is in the middle of the handset. The oscillating armature drive is designed so that this or the motor shaft automatically centered in the off state by means integrated in the drive means such as spring means.

The brush head is mounted perpendicular to the drive axle, so that the motor axis is not loaded in the longitudinal direction in the case. The pressure that happens during mounting is not transmitted directly to the engine. The advantage of disassembly is that the motor shaft is not pulled out of the motor.

In the aforementioned movement of the brush head, it is so that the fixed on the brush head bristles take over the movement but still make some additional movement. Due to their flexibility, they overshoot laterally at the reversal point of the movement. That is, the bristles are stimulated and overshoot by the movement. The system is preferably designed so that the bristles are near the resonant frequency.

The bristles are preferably 90 ° to the direction of movement that is to the arc of the movement. In the present case, the bristle field is parallel to the drive axis and perpendicular (90 °) to the motor axis. By this arrangement it is achieved that the distance between the motor axis and the bristle surface is as short as possible.

The motor provides a movement from 100 Hz to 250 ° Hz, preferably from 150 Hz to 200 Hz. In the present design, the normal operating frequency is substantially 170 Hz. The system is designed to integrate a boost mode, which is maintained by a permanent Pressure on the on-off switch is executed. The boost mode has a frequency of around 185 Hz to clarify the specified frequency. This is understood to be the complete cycle of the movement, ie the movement mode starts in the middle, deflects to the right, returns to the center, deflects to the left and ends in the middle.

With the oscillating armature motor, a covered angle of movement of 1 ° to 10 °, preferably from 2 ° to 4 ° is reached. In the hand-held device, a lateral stop is preferably predetermined in the area of the motor axis / drive axis, so that the motor is not overshooted or overloaded.

The oscillating armature motor is designed so that elements that are permanently magnetized are integrated on the motor shaft. Around the motor axis elements are arranged, which are not permanently magnetized, they are powered by energy from the battery and it forms a field, which rotates the magnets on the motor axis or the motor axis rotatably.

To control the motor, the motor can be supplied via a rectangular signal or via a rectangular current supply. When the motor is energized in this way, for the specific Hertz number of 170 Hz to 180 Hz, the turn-on time (current turn-on time) throughout the cycle is between 30% and 60%, preferably between 35% and 55%. Converted in seconds, this means that the switch-on time between 1.5 ms to 4.5 ms is preferably between 2 ms and 4 ms, the exact time is of course system-specific because it depends on a wide variety of factors. A quieter movement is achieved if the movement is not controlled by a rectangular signal, but sinusoidal. The engine "runs" quieter and it is achieved less noise.

Specific features can be implemented in the handheld device or in the motor control. For example, a zone timer, which gives the application a certain timing. The zone timer tells the user when to handle a next zone. This is important because too long a treatment, for example on the face, can lead to skin irritations. For this purpose, between 2 and 8 preferably 3 or 4 zones are defined or the corresponding number of signaling is defined. Further, a time of 5 seconds to 30 seconds, preferably from 8 seconds to 25 seconds, which corresponds to the treatment time per zone. The necessary zone change is then signaled, for example, by stopping the engine, changing the frequency, visual indication, etc.

Another safety feature to prevent over-treatment of the skin can be an auto-off timer. The motor stops automatically after a certain application time. This time is preferably in the range of 15 seconds to 120 seconds.

To the brush head and a so-called head quiver is provided. As a head quiver is a protective cap for the brush head understood, which is attachable to the brush head and which is intended to protect, inter alia, the bristles during storage.

In its basic form, the head quiver is virtually identical to the floor plan as the brush head is shaped in its lateral outer shape so that it optimally fits the brush head. The basic shape of the head bag is a cylinder, which is completely open on one side and beveled on this opposite side. The lateral surface is also open on one side, this side is called insertion opening.

The open side is designed in such a way that, despite the interface structure on the underside of the brush head, the brush head can be optimally inserted into the head quiver. In the application, the brush head is pushed through the insertion opening in the head quiver. In this case, the top plate or the upper edge is guided laterally in between the upper and lower web on the head quiver with respect to the position parallel to the bristles. When inserting the lateral surface is elastically pressed laterally so that the brush head can be retracted into the head quiver. In the final position of the brush head in the head quiver, the lateral surface is completely relieved or only slightly tensioned, because it creates a kind of locking the brush head with the head quiver. The lateral lateral surface at the insertion opening comes to lie behind the maximum diameter. This slipping out of the brush head is ensured from the head quiver. In the end position of the brush head is located at the front end of the stop surface in the head quiver, he is on the side of the upper and lower web and the lateral surface on. At the rear end of the brush head is exposed.

The upper bridge is provided in the region of the insertion opening with an inlet geometry, so that the upper edge can be better inserted into the groove between the upper and lower web.

The upper and the lower web are not completely formed over the entire lateral surface, since otherwise the necessary for the insertion of the brush head in the head quiver elasticity is not achieved because the body is too rigid. Due to this configuration, the flexibility can be achieved with the thinness of the lateral surface of the head bag. The lower web is laterally over 50 ° to 80 ° preferably formed over 55 ° to 70 °, the upper web each laterally over 60 ° to 120 °, preferably about 80 ° to 105 °. In this case, no web is formed in the region of the stop surface.

Between the upper and the lower bridge is virtually formed a groove. The groove has a structure opposite the upper edge of the top plate, so that they fit together optimally. Preferably, this is rounded and has a diameter of 1 mm to 2.5 mm, preferably 1.2 mm to 1.6 mm, matched to the upper edge of the brush head. The diameter of the head bag is matched to the brush head.

The upper end surface is in the final state of the introduced brush head at an angle to the top plate of 5 ° to 30 °, preferably from 10 ° to 15 °.

The head quiver is designed so that it can be used both for the brush head on the handset and for the brush head without a hand-held device.

If the brush head is used with the handset, the handset can be turned upside down and it reaches a stable position. The resting points are in the case in the lower part of the handset and on the other hand serves the upper end surface of the head box as a support surface. This stabilizes the situation. In both cases of application, in any case, the bristles are protected from damage.

Due to the storage of the brush head in the head quiver and the placement of the whole on the upper end surface of the head box, the bristles come to rest. This has advantages, among other things, when the brush head is washed out, because it allows the remaining water to drip off better.

Further advantages emerge from the following description of the drawing. In the drawings, embodiments of the invention are shown schematically. The drawings, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.

Fig. 31 shows diagrams for comparison of the excitation according to the invention with excitation according to the prior art.

In the figures 1 to 5, the face brush or massage brush is shown with brush head mounted in different representations. This body care device has a handset (1) and a brush head (2). The brush head (2) is provided with a plurality of bristles (3). In particular, it is intended to combine a plurality of bristles (3) in a bundle of bristles (4).

The handset (1) has a housing (5). The housing (5) consists of a front and a rear shell part (20, 22), which are connected via a separating seam. In the housing (5), a drive element (6) is arranged.

It can also be seen in particular from the different representations in FIG. 1 that the brush head (2) has a carrier element or a carrier plate (13) in the area of a side (12) facing away from the bristles (3), which essentially defines a circle in a plan view and bordered by a rim (14).

For an arrangement of the brush head (2) on the housing (5) of the brush head (2) with the secondary part (9) of the adapter (7) is inserted into a recess (11) of the housing (5) and thereby comes into contact with the primary part (8) of the adapter (7).

In the region of the rear side (12) of the carrier plate (13), webs (15) extend starting from the edge (14) in the direction of the secondary part (9). In the region of one or more of the webs (15), a survey (16) can be arranged, for example in the form of a pin. To protect the brush head (2), it is possible to provide the housing (5) with a removable cover (17). In particular, it is thought to arrange the cover (17) laterally pushed.

In the lower area of the handset (40), the charging socket (26) with the charging socket breakthrough (27) is visible. In the front switching part (20) of the on-off switch (30) and belonging to the on-off switch break-through (31) can be seen.

The on the handset (1) patch brush head (2) is located in the upper part of the handset (39). Side of the brush head (2), the gripping recesses (43) on the handset (1) can be seen, further in the side view, the gripping aids (52) on the top plate (50) can be seen.

Figures 6 and 7 show the handset (1) without brush head (2). As a result, the brush head recess (42) in the handset (1) is visible. Arranged therein is also the adapter (7) recognizable. The side of the brush head recess (42) lying gripping recesses (43) are also shown.

The brush head (2) without hand-held device (1) is shown in FIGS. 8 to 10 with bristles (3) and in FIGS. 11 to 15 without bristles (3).

The arrangement of the bristle holes (53) in the described circles is clearly visible from the front in the plan view of the brush head (2). The grading of the bristle bundles (4) with less high bristle bundles (4) in the center is clearly visible in the sectional view.

The interface geometry with the secondary part (9) attached to the brush head (2) is easily recognizable. The arrangement of the snap elements (56), the transmission elements (57) and the orientation elements (58) is clearly visible in the various views. The different layers of the elements and the height conditions are clearly visible. The adapter (7) is shown isolated in Figures 16 to 20. The primary part (8) of the interface is formed on the adapter (7). Together with the already shown primary part (8) on the brush head (2) it forms the coupling structure / interface structure for connecting the brush head (2) with the handset (1).

In the lateral area of the adapter (7), the bead (61) and the cylindrical surface (60) are clearly visible. The orientation recess (62) is also shown. The height ratios are shown and it can be seen that the central sleeve (64) projects beyond the lateral area of the adapter (7).

FIG. 21 shows the interaction between the adapter (7) or the primary part (8) and the brush head (2) or the secondary part (9). On the left side of the illustration it can be seen how the transmission element (57) rests against the bead (61), while on the right side it can be seen that the snap element (56) engages over the bead (61). Thus, an element abuts on one side of the bead (61) and another element on the other side of the bead (61).

The structure of the drive shaft (34) and motor axis is shown in FIG. From the partially sectioned perspective view in Figure 3 it can be seen that the drive element (6) is a motor (10). Depending on the specific design realization of the drive element (6), it is possible for the brush head (2) to perform oscillating movements, tilting movements, rotational movements and / or lifting movements. In the present case, a wiping motion is realized.

The achievement of a low total weight has therefore a special meaning, so that can be done with a low engine performance. This results in a low energy consumption and thus a lower required capacity of the accumulator or the battery in question. In addition, the noise can be minimized and the vibration behavior optimized (minimum energy consumption for a given rotation angle). A corresponding optimal structural design also leads to a sufficient deflection at a predetermined desired frequency can be achieved.

In Figures 23 and 24, the head quiver (70) is shown in use on the brush head (2), while Figures 25 to 28 show the head quiver (70) isolated.

In Figure 23, the auxiliary line shows how the handset (1) can be placed on a plane with the head quiver (70) attached. By forming the head box (70) with a sloped upper end surface (77), stable storage is achieved.

How the over-edge (54) of the head plate (50) with the upper and lower web (73, 74) of the guide in the head box (70) play together is clearly visible. The upper edge (54) is retracted between the two webs. It is also clearly visible that the head quiver (70) does not lie close to the bristle field at all points and there is free space between the bristle ends and the head quiver (70).

In the detail of the head box (70) the already mentioned elements of the head box (70) are clearly visible. It can also be seen, the upper end surface (77) which is at an angle. The introduction of the brush head (2) in the head quiver (70) necessary insertion opening (78), which is quasi framed by the lateral surface (76). The abutment surface (75) is also visible as the inlet slope of the upper web (73).

A variant of the brush head (2) is shown in FIGS. 29 and 30. Certain bristle bundles (4) are replaced by a care body (80). This gives off in the application certain care substances.

The diagrams in FIG. 31 show a clarification of an interaction of brush head, adapter and motor. In the upper part of the drawing, a conventional type of excitation via a rectangular signal is shown. According to the invention, a modulated square-wave signal is used, as a result of which a sinusoidal excitation occurs. This allows a higher engine activity and a lower noise can be achieved.

A pulse width modulated signal is provided by which a sinusoidal oscillation is impressed as a current.

A specific aspect of the present invention relates to the dimensions of the movements of the components that occur. In particular, the values specified below are of importance for a health-promoting effect. If, for example, the skin is brushed too hard, too strong or too fast, it may cause damage to the upper layers of the skin. There are thus both too high frequencies during brushing and too high mechanical loads to avoid.

According to the invention, the aforementioned boundary conditions are met. As a result, damage to the skin, for example, by rubbing or by grinding the horny layers can be avoided. Also according to the invention damage to the skin by a mechanical action, for example, too high pressure, excessive tension, excessive friction, excessive elongation, by unfavorable massage or by pinching or pulling avoided. In particular, the construction according to the invention and the method according to the invention also permit use by sensitive persons with easily irritable follicles. Such follicles are often located in the dermis below the epidermis. Also, an application is possible in people who are predisposed to acne vulgaris, which induces a so-called acne Mecanicca.

The inventive combination of the frequency and deflection ranges ensures the avoidance of mechanical damage even with a sensitive skin.

As already mentioned, the device according to the invention can be used both as a face brush and as a massage brush. A production can be carried out, for example, at least for individual components in an injection molding process. Plastic is preferably used here. A brushing of the brush head preferably follows in an anchor punching process. Here, a basic body is first prepared with blind holes and then the bristles are folded and secured with an anchor.

With regard to the drive fundamentally different variants can be realized or combined with each other. It is preferable to generate a wiping back-and-forth motion. This can be done left or right with respect to the motor axis. Preferably, the bristle field is perpendicular to the motor axis. A starting position for the movement is preferably in the middle of the device. This has the consequence that after each application again and again a positioning in the middle is realized. A provision can be made by means in the drive, for example by a spring.

With regard to the assembly of the brush head, this can preferably be realized at right angles to the motor axis. This protects the drive and the axle is not pulled out of the engine.

With regard to the generated movement, the movement can take place, for example, in the form of a movement in a plane with a normal, which corresponds to the motor axis. It is also possible that the motor allows movement on a circular arc. According to another variant, the interaction of the elements results in a movement on a circular arc, whereby ultimately a wiping movement is generated. In addition, a stroke movement in the direction of the motor axis can also be generated.

With regard to the dimensions of the movement with respect to the bristles, the distance of the motor axis from the bristle tips can be taken into account. With respect to the movement of the bristles, overshoot, excitation by movement, overshoot by excitation or excitation in the system can be realized, with the bristles near resonance. Typically, the bristles are at an angle of 90 degrees to the direction of movement. Preferably thus in 90 degrees to the arc of the movement. Alternatively, the bristles may be disposed at an angle of 90 degrees to the motor axis. With regard to the dimensions of the movement, different variants can also be realized. With regard to the frequencies, for example, it is possible to realize a range from 100 Hz to 250 Hz, preferably from 150 Hz to 200 Hz. A normal operating frequency may be about 170 Hz. When implementing a booster, the frequency can be 185 Hz. An activation is possible, for example, after a push on a switch. This can be pressed after a certain time and preferably the booster runs as long as the pressure on the switch takes place.

The frequency can correspond to the length of a cycle, which means a whole movement of a motor axis. For example, a start from the center can be considered, with the deflection initially left, then center, then right and then again passes through the middle.

With regard to the dimensions of the movement, the angles or deflections are also important. In particular, this relates to a covered angle of movement. An angular range can be realized on each side from the middle position. A corresponding deflection angle is preferably 1 degree to 10 degrees, more preferably 2 degrees to 4 degrees. The deflection can be unloaded without head plus minus 3 degrees.

Also to be considered are the moments of movement and the ratios of speed to angle.

Particular variants of the invention relate to the use of a zone timer. You can take into account the number of zones and the time per zone. The number of zones may be, for example, 2 to 6, preferably 3 to 4. The time per zone may preferably be 5 seconds to 30 seconds, preferably 8 seconds to 25 seconds.

An "auto-off" function can be realized after a period of use. Preferably, this is in a range of 15 seconds to 120 seconds.
