DETAILED DESCRIPTION OF THE INVENTION

The skin care device includes a drive unit, as well as a first and second nozzle. The device for skin care can also be made in the form of a kit with two, three or more nozzles. In some embodiments with a drive unit, only one nozzle can be used at a time. In addition to this, or alternatively, the drive unit may be configured to operate simultaneously with two or more nozzles. However, it has been determined that embodiments are preferred in which the drive unit can only work with one nozzle at a time. Accordingly, the nozzle can be removably mounted on the drive unit. The drive unit is usually driven by an electric motor. The electric motor can operate on battery power, such as a rechargeable battery. Drive units that are connected to the mains via a connecting cable can also be used.

The first embodiment may comprise a skin treatment element, for example, made in the form of a brush, and may comprise an output element. Alternatively, the output element may be part of a drive unit. Alternatively or in addition to this, the drive unit may comprise an additional gear unit or a torque transmission member.

The second nozzle may be a nozzle for depilation or hair removal. The depilation nozzle is used to remove hair from the skin by cutting it slightly above the skin level, but close enough to the skin surface. In fact, depilation can be considered as shaving. Therefore, a wet shaving process can be used for depilation, preferably with a razor cartridge containing two, three, four or more blades. Alternatively, an electric shaver can be used for depilation, in which a moving block of blades is moved relative to a mesh containing hair holes. Another useful embodiment of the present invention comprises a first epilator nozzle. The process of hair removal is the extension and subsequent plucking of hair from the skin. That is, all hair is removed from the skin. Both processes, and especially the hair removal process, cause some stress for the treated surface of the skin. The effectiveness of a process, such as an epilation process, can be improved by increasing the speed of hair removal or the number of plucking micro forceps. However, such solutions, despite the increase in efficiency, increase the stress on the skin and sometimes can even cause a sensation of pain. Therefore, there remains a need for a more gentle, but more effective hair removal process.

It has been determined that using a skin care device with a first nozzle provides significant benefits. Brushing the skin provides massage and a cleansing effect. The appearance of the skin improves. In addition, treating the skin with the first nozzle can improve the results by subsequent processing of the skin with the second nozzle. So, for example, it was determined that hair removal (in particular, hair removal) by the second nozzle is more effective if the skin was pre-treated with the first nozzle. Although this effect is not yet fully understood, it can be assumed that the first nozzle removes surface particles of the skin, thereby improving access to hair. Due to this, the hair removal efficiency of the second nozzle is increased.

It was determined that this effect becomes especially pronounced if the rotation speed of the first nozzle is correctly selected. Thus, it is preferable that for the drive, which can be used with both the first and second nozzles, in particular with the epilation nozzle, the second nozzle contains a gear block and the first nozzle contains a gear block, and thus the gear block contained in the first nozzle , provided a reduction gear ratio from at least 1.25 to 10. Gear ratios from 1.25 to 5, or from 1.25 to 4, or from 1.5 to 3 are also suitable. The reduction gear provides a lower brush rotation speed compared to rotation speed motor output shaft. That is, the brush rotates more slowly than the motor output shaft.

If the first nozzle contains a gear block providing the first reduction gear ratio and the second nozzle contains gears providing the second reduction gear ratio, then the first reduction gear ratio must exceed the second reduction gear ratio by 1 to 5 times, or 2 to 3 times .

In addition, it was determined that the brush head contained in the first nozzle should preferably have an average diameter in a certain range. If the brush has a round shape, then the "average diameter" corresponds to the diameter in the usual sense of the word. If the brush has a non-circular shape, then the average diameter refers to the diameter of a round brush having the same area as the non-circular brush under consideration. It was determined that the average diameter in the range from 1 cm to 7 cm or from 3 cm to 5 cm is most suitable. This diameter provides ease of use of the skin care device and at the same time a sufficiently gentle treatment of the skin and application of suitable force to the skin when the user holds the skin care device in his hand. In addition, it was determined that the device works efficiently and at the same time gently enough if the ratio of the average brush diameter in centimeters to the reduction gear ratio is from 1 to 2. Thus, for example, a reduction gear ratio of 2 is suitable for a brush with a diameter of 4 cm This allows the use of a battery-powered drive unit while at the same time providing sufficient force for effective skin treatment. A properly selected gear ratio will also help prevent possible damage to the drive unit. Namely, when the user manipulates the device with the first nozzle installed, not too much force will be transmitted to the drive unit. From this point of view, the gear ratios described above are suitable.

In addition, for additional protection of the drive unit and the gear unit, a disconnection mechanism may be provided. Such a disconnection mechanism for the first nozzle can provide a separation of the chassis carrying the skin processing element, for example a brush, from a rotating support member supporting the chassis and connected to the gear unit and, accordingly, to the drive element. A useful embodiment is a disconnection mechanism implemented according to the following scheme: the drive unit comprises an output element, for example, a gear unit, and a rotating support element containing protrusions. That is, the nozzle may comprise a skin treatment element and a chassis for a skin treatment element, wherein the chassis may comprise a plurality of recesses cooperating with the protrusions of the rotating support element of the drive unit. The chassis can be engaged with recesses, as a result of which it will be supported by a rotating support member. From a position in which the chassis is supported by a rotating support member, it can be disengaged from the recesses. A useful embodiment are recesses in the form of a gear ring, that is, a plurality of recesses closely spaced to each other. A useful embodiment are protrusions in the form of hooks, for example resiliently springy hooks.

It is also useful to connect the first nozzle to the drive unit by means of an eccentric. This provides an effective way of driving the first nozzle.

Useful is the following downshift scheme for the first nozzle: the first nozzle comprises a drive shaft for transmitting torque from the drive unit to the drive axis; the drive shaft is connected to the gear; the gear is meshed with the ring gear and the ring gear is connected to the drive axle.

The present invention also provides a method for caring for human skin, comprising the following steps:

treating the skin with an oscillating brush using a skin care device comprising a drive unit and a first nozzle comprising a brush;

removing hair from the skin using a skin care device comprising a drive unit and a second nozzle comprising an epilation or depilation unit,

while the drive unit can operate at a first predetermined speed, which is used at both stages.

The method can be used with a different sequence of steps. So, for example, hair can be removed from the skin first, and at a subsequent stage, the skin can be treated with an oscillating brush. This method does not increase the efficiency of hair removal, however, it can provide massage and analgesic effect. The analgesic effect can be enhanced if the method contains an additional step of applying the lotion to the skin or brush.

Alternatively, the treatment of the skin with an oscillating brush can be carried out before removing hair from the skin. It was determined that such a sequence of steps increases the efficiency of hair removal. In one embodiment of the method, brushing the skin is carried out over a period of time ranging from 24 to 72 hours before removing hair from the skin. Brushing the skin can be considered as a step in preparing the skin for the hair removal process. As explained above, the removal of particles of skin can play a certain positive role. At this stage of brushing, the skin is subjected to a certain stressful effect. Waiting for 24 to 72 hours before performing the next stage of skin treatment allows the skin to recover. Alternatively, the treatment of the skin with an oscillating brush can be carried out over a period of 1 to 60 minutes before removing hair from the skin. Despite the fact that the skin is experiencing a bit more stress, such a shortened pause between the stages allows you to perform both stages in essence at the same time and usually in one place, for example, in the bathroom, and accordingly allows you to carry out the hair removal procedure more efficiently in terms of costs time. In both cases, pre-treatment of the skin with a brush significantly increases the efficiency of the hair removal process, especially, but not only if the hair removal process is used. And a special effect is achieved if the first and second nozzles are used with the reduction gear ratios described above.

It is particularly preferable to use the same drive unit with both the first and second nozzle. Even more preferably, the drive unit can be used with various predetermined rotational speeds, for example, with a first (slower) and second (faster) rotational speed. Different users, as a rule, choose the rotation speed in accordance with their personal preferences. The user's preferences may be affected by skin type. So, for example, users with more sensitive skin, as a rule, choose a lower speed of rotation. The user can use the first and second nozzles with the same drive unit and at the same speed set by their own preference. So, for example, if a slower rotation speed is used, then both stages of the method will proceed gently enough, which some users may prefer. The reduction ratio of the second nozzle, relative to the gear ratio of the first nozzle, can also be selected taking into account the preferences of most users.

In FIG. 1 shows a skin care device 10 comprising a first nozzle that contains essential essential elements in accordance with the present invention. Thus, the device 10 comprises a drive unit 20. The drive unit comprises a motor which, as a rule, provides a rotational or vibrational motion to a certain output component. The engine is typically an electric motor that can operate on battery power, typically on a rechargeable battery. The drive unit 20 contains a switch 22, which allows you to turn on and off the device and / or select the operating modes of the device. So, for example, switch 22 allows you to select the first rotation speed by moving it to position 24 and the second speed by moving it to position 26.

A nozzle 30 may be attached to the drive unit 20. Many suitable methods for attaching a nozzle are known. Often, a tight fit is often a suitable method. Other nozzles may be attached to the drive unit 20. So, for example, the nozzle 30 can be used as the first nozzle, and in addition, the second and third nozzles can be used, which can also be attached to the drive unit 20. The nozzle 30 shown in this drawing contains a brush 32. The term "brush" is used in this case in a broad sense, to refer to an embodiment that contains bristles made of various materials, well known from other applications. The brush may also contain rubber elements, such as rods or bridges, arranged so that in general they resemble a conventional brush. Outside, the brush 32 is generally round in shape, but other shapes are possible.

In FIG. 2 shows the same device 10 in a side view. This side view shows that the main axis of the drive unit and the axis of rotation of the brush 32 are located at an angle to each other. It was determined that for convenient and efficient use of the device, the most convenient are the angles between the mentioned axes in the range from 90 ° to 135 ° or from 100 ° to 120 °. In this side view, it is also seen that the nozzle 30 comprises a gear unit 60 on which a brush 32 is mounted with a brush chassis 34. The block 60 of the gears is connected with the chassis 34 of the brush by means of a rotating support element 50, which in this view is only visible as some kind of ring-shaped structure.

In FIG. 3 shows a skin care device 10 with a second nozzle mounted thereon, which contains essential essential elements in accordance with the present invention. The second nozzle is an epilating nozzle 40. The epilating nozzle 40 comprises an epilating cylinder 42. The epilating cylinder 42 is brought into contact with the skin to remove hair. The epilation cylinder 42 rotates around its main axis (which in FIG. 3 is extended in the horizontal direction). The rotation is communicated to the cylinder from the drive unit 20, which was described above. On the hair removal cylinder 42 there are micro-tweezers that pull and pluck the hair. To facilitate control of the device, as well as to somewhat reduce pain, rollers 46 are provided in contact with the skin. These rollers can provide additional massage function. Therefore, the present invention also provides a skin care device 10 comprising a drive unit 20, a first nozzle 30 and a second nozzle 40, wherein the first nozzle 30 comprises a brush or other skin treatment element rotating about an axis that is generally perpendicular to the skin surface, and a second nozzle 40 containing rollers 46 rotating around an axis parallel to the skin surface.

In FIG. 4 shows a partial section through a device 10 on which a first nozzle is mounted. In this drawing, you can see the details of the device block 60 gears. Torque from the drive unit 20 is transmitted to the drive shaft 64 (also referred to herein as the input shaft). A gear wheel 66 is installed on this drive shaft. A gear ring gear 68 is installed in conjunction with this gear wheel and is mounted on the drive axis 70. This axis is located at an angle of approximately 110 ° to the drive shaft 64. It has been determined that for convenient and efficient control of the device most suitable are angles ranging from 90 ° to 135 ° or from 100 ° to 120 °. That is, a refractive gear is provided, operating as a two-stage gearbox. The gear ratio (reduction in rotational speed) can be from 1.25 to 10. It has been determined that gear ratios from 1.25 to 5, or from 1.25 to 4, or from 1.5 to 3 are also suitable. Obviously also that this simple and reliable design fits well into the shape and dimensions of the gearbox 60.

The drive axis 70 is parallel (as can be seen in the side view) of the central support axis 72. The central support axis 72 is not a driven axis, but is a support for the rotating support element 50. Accordingly, the central support element 50 has only one degree of freedom - movement around reference axis 72.

The rotating support member 50 includes a rotating plate 52 on which hooks 54 are mounted. The hooks 54 are spring loaded with resilient elements 56. A support plate 58 is mounted on the rotating plate 52. The support plate 58 provides support for a skin processing member (not shown). The rotational-oscillating movement is provided by the rotating support element 50. This movement is transmitted from the drive by the drive axis 70. The drive axis carries an eccentric 74. The eccentric 74 contains an eccentric wheel 76 containing an eccentric pin 78. The finger 78 interacts with a notch (not shown) in rotating plate 52.

The dimensions and their values contained in this document should not be construed as strictly limited to the exact values given. On the contrary, unless otherwise specified, a given value is understood to mean this value in accuracy and all values located in a functionally equivalent neighborhood. So, for example, a value designated as 40 mm should be considered as “approximately 40 mm”.
