[0001] The present invention relates to an epilating apparatus comprising means for extracting
hairs from skin and means for reducing pain by applying stimuli to the skin.
[0002] An epilating apparatus of the type mentioned in the opening paragraph is known from
EP 1 105 017 B1. The epilating apparatus, which is also referred to as depilation system, comprises
an epilation device and a cooling device. The epilation device is provided with epilation
means in the region of a head portion for removing hair. The cooling device is provided
with a skin contact portion which makes contact with a region to be depilated. In
operation, the epilation system is guided by hand over the skin regions to be depilated.
During such a depilation operation, first the skin contact portion of the cooling
device makes contact with a skin portion to be depilated. Subsequently, the epilation
means make operational contact with the skin region which has just been cooled. The
cooling of a skin region to be depilated before epilation has a pain reducing effect.
However, the epilation process will still be regarded as painful by many users.
[0003] DE 100 20 819 A1 discloses an epilating apparatus having means for the mechanical stimulation of the
skin to be epilated. During operation of the known apparatus said means are brought
into contact with the skin to achieve a pain reducing effect. The known apparatus
is provided with a separate means for cooling the skin in the form of a glove having
a compartment wherein a cooling pack can be accommodated. The user can place said
glove over one hand and apply cold to the skin by moving the glove over the skin before,
during or after the epilation process.
[0004] WO-A-01/13757 discloses an apparatus for hair removal comprising a hair-clamping member that can
be vibrated by a vibration mechanism. After a hair is clamped by the hair-clamping
member, the hair-clamping member is vibrated in order to apply vibrations to the hair
and the hair root. By means of said vibration the connection between the hair and
the skin is weakened, so that the hair can be extracted from the skin. As a pre-treatment
procedure, the skin regions to be treated by the apparatus may be heated or cooled.
[0005] It is an object of the present invention to further reduce pain during epilation.
[0006] In order to achieve this object an epilating apparatus in accordance with the invention
is characterized in that the means for reducing pain comprise means for applying to
the skin a combination of at least two of the stimuli heat, cold and vibration, wherein
the means for applying said combination of stimuli and the means for extracting hairs
are mutually connected in a serial configuration relative to a preferred direction
of movement during operation of the epilating apparatus. The application of two or
more stimuli has an additional pain reducing effect, which can be explained as follows:
According to the "Gate Control Theory" (Melzack and Wall 1965), a neural mechanism
in the spinal cord acts like a gate, i.e.opening and closing, to regulate the flow
of nerve signals from the body periphery to the brain. The status of the gate (opened,
closed or several intermediate conditions) is controlled by the brain via signals
like emotions, expectations, memories, etc. All information from receptors in the
body has to pass the gate to be transmitted to the brain and to be defined as an emotion
(e.g.: pain, heat, coldness, etc.) and, furthermore, to start a reaction, wherein
the information pain, heat, coldness, itchiness is transmitted via nerve tissue at
different transmission speeds. The strategy to reduce the pain during epilation is
to close the gate for the bad pain signals as far as possible, by the brain, via generating
good sensations and emotions. By using two triggers (for example cooling and warming),
on the one hand more receptors of different nature can be stimulated (1 cm
2 of skin on average contains 2 heat, 13 coldness, 25 pressure and 200 pain receptors),
so the stimulation effect is significantly increased. On the other hand the brain
prefers the pleasant signals which are associated with two sensations (in the present
example cooling and warming) and blocks the transmission of the pain signals by closing
the gate a little more or by shutting it completely The fact that the brain is irritated
by receiving and recognizing the effect of two contrary principles has an effect of
diversion. Additionally, for example, the pre-warming of the skin has a relaxation
effect, so that easier hair removal is possible. This effect becomes more important
for all subsequent epilation strokes, because the skin has already been contacted
by the cooling function of the previous stroke.
[0007] In preferred embodiments of the epilating apparatus in accordance with the invention,
the means for reducing pain comprise first means which apply at least one of the stimuli
and second means which apply at least another of the stimuli. By assigning a stimulus
to the first and second means, respectively, a variety of arrangement options can
be realized. Furthermore, each means can be optimized separately regarding the stimulus
to be applied by the means. However, it is also within the scope of the present invention
to combine the first and second means in a constructive manner.
[0008] In this context it is preferred that the first means and the second means are arranged
in a serial configuration relative to a preferred direction of movement during operation
of the epilating apparatus. A serial arrangement of the first and the second means
allows for a sequential application of the stimuli to the skin portion being treated
with the epilating apparatus. In addition, the application of the stimuli occurs in
a close temporal correlation, thus exciting the different receptors for enabling a
pain reducing effect.
[0009] Alternatively, or additionally, the first means and the second means are at least
partially arranged in a parallel configuration relative to the extracting means. The
parallel configuration provides for a smooth operation flow and a reliable cooperation
between the first and second means and the extracting means.
[0010] In preferred embodiments of the epilating apparatus in accordance with the invention,
the extracting means, the first means and the second means each comprise an active
surface, and the shape of the active surface of the first means and/or the shape of
the active surface of the second means are adapted at least partially to the shape
of the active surface of the extracting means. The at least partial adaption of the
shapes of the active surfaces of the first and second means to that of the extracting
means allows for a reliable application of the pain reducing stimuli to the treated
skin. In particular, by surrounding the active surface of the extracting means by
the active surfaces of the first and second means, a good pain reducing pre-treatment
of the skin before epilation and immediate aftercare of the epilated skin is achieved.
[0011] A particular embodiment of the epilating apparatus in accordance with the invention
is characterized in that at least the first means and the second means are arranged
in front of the extracting means relative to a preferred direction of movement of
the extracting means during operation . The application of a pain reducing combination
of two stimuli before the epilation operation generates the pain masking effect before
the pain receptors are excited. Thus, the transmission of the pain information generated
by the pain receptors is reduced.
[0012] Further embodiments of an epilating apparatus in accordance with the invention are
characterized in that at least the first means and the second means are arranged behind
the extracting means relative to a preferred direction of movement of the extracting
means during operation. This arrangement provides good visibility of the epilating
process and enhances the observation of the epilation operation by the user.
[0013] A particular embodiment of an epilating apparatus in accordance with the invention
is characterized in that at least the first means are arranged behind the extracting
means and at least the second means are arranged in front of the extracting means
relative to a preferred direction of movement of the extracting means during operation.
The skin is pretreated before the epilating process occurs, thus lowering the sensitivity
for pain, while the after-treatment afterwards reduces the painful sensations of the
epilating process and prevents such a sensation from remaining after the epilating
process. Therefore, the painful sensation is covered with positive sensations during
every step of the epilating operation.
[0014] In accordance with a further development of the epilating apparatus, at least an
active surface of the first means and an active surface of the second means match
at least partially in a complementary manner. The matching of the active surfaces
applying different stimuli provides an arrangement which enables a locally very close
application of different stimuli. In particular, there may be provided an active surface
for applying one stimulus, e.g. vibration, protruding from the active surface applying
a different stimulus, e. g. cold. Thus, a locally very close application of two different
stimuli can be achieved by still separating the active surfaces of the different stimuli
at the same time.
[0015] In alternative embodiments of the invention, at least an active surface of the first
means and an active surface of the second means coincide. If two different stimuli
are applied by one active surface, the overall size of the means for reducing pain
may be reduced.
[0016] Also in preferred embodiments of the epilating apparatus in accordance with the invention,
it is preferred that at least the first means and the second means are adapted to
contact a skin portion synchronously. Synchronous excitation of two or more different
receptors in a skin portion results in a pain masking effect, even if the different
receptors are localized in different skin portions, as long as the nerval transmission
of the information passes the same gate.
[0017] A particular embodiment of the invention is characterized in that the means for reducing
pain apply the stimuli cold and heat. The combined application of the stimuli heat
and cold additionally has a diversion effect. The brain receives and recognizes two
contrary sensations and is irritated. An additional advantage may also arise if the
heat is applied before the hair extraction occurs. Pre-warming the skin has a relaxational
effect on the skin and may ease the hair removal. This effect may gain more importance
if the same skin portion has to be epilated in several runs. If the after-treatment
provides a cooling of the skin, the skin has to be relaxed by warming it before the
next epilation step can be performed. Alternatively, the application of the cold stimulus
before extracting hairs and warming the skin afterwards is also possible as well as
a combined application of the two stimuli at the same time.
[0018] Another particular embodiment of the invention is characterized in that the means
for reducing pain apply the stimuli cold and vibration. This embodiment excites the
coldness and pressure receptors in the skin, thereby evoking the pain masking effect.
This combination in particular facilitates the usage of one active surface for two
different stimuli.
[0019] Yet another preferred embodiment of the invention is characterized in that the means
for reducing pain apply the stimuli heat and vibration. This embodiment has similar
advantages to the embodiments described above.
[0020] In accordance with a further aspect of the invention, the above object is solved
in that the means for reducing pain apply cold to the skin on an electrical basis.
Generating the cold to be applied to the skin on an electrical basis provides a significant
advantage for the user, compared to solutions using a cold storage that has to be
charged separately, for example in a refrigerator. Since the epilating apparatus usually
provides a power supply for driving the extracting means, generating the cold on an
electrical basis can be realized easily in many cases. Time consuming cooling of the
cooling means can be omitted, leading to a continuous and more comfortable epilating
process.
[0021] In particular, it is preferred that the means for reducing pain comprise at least
one Peltier element. A Peltier element may be used for generating the required low
temperatures for the cold stimulus. Alternatively, it can be employed for providing
high temperatures for the heat stimulus. In a further embodiment of the application,
one Peltier element for the two temperature stimuli, namely heat and cold, can be
envisaged . The use of a Peltier element has several advantages: The electrical power
supply of a Peltier element results in more comfortable handling of the epilating
apparatus. The small overall size of a Peltier element and its ability to be customized
makes a Peltier element an adequate temperature source for an epilating apparatus.
[0022] Alternatively, or additionally, the means for reducing pain comprise at least one
resistor. The generation of the heat stimulus can be achieved by employing a resistor.
This solution provides a cheap and reliable heat source.
[0023] Furthermore, alternatively or additionally, the means for reducing pain comprise
at least one PTC. A PTC with its typical characteristics well known to one skilled
in the art can also be applied as a heating element in an epilating apparatus in accordance
with the invention.
[0024] In some preferred embodiments the means for reducing pain are detachable from the
epilating apparatus, at least partially. In particular, if the means for applying
the cold stimulus do not work on an electrical basis, it may be advantageous to provide
at least one detachable element. Such an element can be separated from the epilating
apparatus and can be recharged at a different place. It may also be advantageous for
other means for reducing pain to be detachable in order to provide different embodiments
for different skin regions. It is even possible to provide the epilating apparatus
with different stimuli for different skin regions.
[0025] In some embodiments of the epilating apparatus in accordance with the invention,
the cold source for the means for reducing pain is a cold storage. This is a cheap
and effective cold source for applying the cold stimulus to the skin.
[0026] Another embodiment according to the invention is characterized in that the means
for reducing pain comprise a cylindrical element for contacting a skin portion, the
axis of the cylinder being perpendicular to a preferred direction of movement during
operation. The cylindrical element is well suited for transferring pain-reducing stimuli
to a skin portion. It may be employed, for example, for transferring the cold stimulus
or the heat stimulus and simultaneously the vibration stimulus. In particular, pins
protruding from the surface of the cylindrical element have a vibrating/massaging
effect on the skin when the cylindrical element is rolled over the surface of the
skin.

invention will be explained in detail in the following with reference to the accompanying

[0028] Referring to Figure 1A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating member 12, first means for reducing pain
in the form of a cooling member 16 as well as second means for reducing pain in the
form of a vibration member 20. The epilating member 12 is implemented in a housing
24 and comprises an active surface 14 for contacting a skin portion. It also comprises
a number of pinching discs 26, drawn schematically and not to scale. In operation,
the pinching discs 26 rotate around an axis 28. The epilating member 12 provides the
hair removing effect by clamping hairs between the pinching discs 26 and pulling out
the hairs from the skin by a rotational movement of the pinching discs 26. The epilating
member 12 is connected with the vibration member 20, the vibration member 20 being
in front of the epilating member 12 relative to the preferred direction of movement
29 during operation of the epilating apparatus 10. The epilating member 12 is also
connected with the cooling member 16, which is arranged behind the epilating member
12 relative to the direction of movement 29 of the epilating apparatus 10. The vibration
member 20 comprises a row of pins 21 arranged perpendicularly to the preferred direction
of movement 29 during operation and parallel to the axis 28. The pins 21 have active
surfaces 22 for contacting a skin portion and applying the vibration stimulus. The
vibration member 20 as well as the epilating member 12 are connectable to a power
supply (not shown), alternatively batteries may be applied. The cooling member 16
comprises a housing 17 and an active cooling surface 18. Furthermore, the cooling
member 16 comprises a storage element (not shown) for providing a cold source; alternatively
it can be provided with an electrical cooling element.
[0029] Figure 1B shows schematically the arrangement of the active surfaces 22, 14, 18 of
the vibration member 20, the epilation member 12, and the cooling member 16 of the
apparatus in accordance with Figure 1. In operation, the active surfaces 22, 14, 18
of the epilating apparatus 10 are brought into contact with the skin to be epilated.
With the active - surfaces 22, 14, 18 in contact with the skin, the epilating apparatus
10 is moved along its preferred direction of movement 29 during operation. The pins
21 of the vibration member 20 perform a reciprocating movement along their longitudinal
axis, which extends perpendicularly to the rotation axis 28 of the epilating member
12, and also perpendicularly to the preferred direction of movement 29 during operation
, i.e. perpendicular to the surface of the skin to be epilated. This movement of the
pins 21 excites the pressure receptors in the skin and results, as described above,
in a first pain masking effect. After the vibration member 20 has treated the skin
portion, the hairs being present on the surface of the skin are removed by the epilating
member 12, in particular by the pinching discs 26. Since the pain masking effect caused
by the vibration stimulus is still present when the respective skin portion is treated
by the epilation member 12, the painful sensation caused by the extraction of the
hairs is reduced. After the epilating process the respective skin portion gets into
contact with the active surface 18 of the cooling member 16. Thereby, the skin is
cooled to a lower temperature, causing a second pain masking effect. The combined
application of two pain reducing stimuli, i.e. cold and vibration in the embodiment
shown in Figures 1A and 1B, reduces the perception of pain by the user significantly.
It has to be mentioned that the frequency and intensity of the signals being transmitted
via the nerve tissue can be maximized for an optimum pain reduction effect. For example,
it has been found that a cooling surface of 2 - 12 cm
2, in particular about 6 cm
2, and a temperature of 10 - 30°C, in particular 16 - 27 °C provide a good cooling
effect. Furthermore, a vibration frequency of approximately 20 - 500 Hz, in particular
approximately 100 Hz, using certain massage members has proven to provide a good pain
reducing effect.
[0030] Referring to Figure 2A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating member 12 and means for reducing pain
in the form of a cooling and vibration member 36. The epilating member 12 corresponds
to the one shown and discussed with reference to Figure 1. The member 36 combining
cooling and vibration comprises a housing 37 with an ice reservoir (not shown) providing
a cold source for cooling the skin. In contrast to the active surface 18 shown in
Figure 1, the active surface 38 of the cooling and vibration member 36 is movably
connected with the housing 37. In the housing 37 there is further provided a suitable
electrical drive for creating the vibration of the element 36.The epilating member
12 is attached to the cooling member 36 by a connection between the respective housings
24, 37.
[0031] Figure 2B shows schematically the arrangement of the active surfaces 14, 38 of the
epilation member 12 and the member 36 for cooling and vibrating simultaneously. In
operation, the epilating apparatus 10 is moved along its preferred direction of movement
29 , contacting a skin portion by the active surfaces 16, 38 of the epilating member
12 and of the cooling and vibration member 36, respectively. In this embodiment, no
pain masking is performed before the epilating process. After the pain exciting epilation,
the surface 38 gets into contact with the already epilated skin portion and applies
the stimuli cold and vibration to it. The cooling and vibrating surface 38 not only
provides a good thermal contact between the active surface 38 and the skin by exerting
a certain pressure to the skin surface, but also enhances the thermal flow from the
ice reservoir in the housing 37 of the cooling member 36 to the vibrating active surface
38. Alternatively, the vibrating surface 38 could also be cooled by electrical means
or could provide a heat stimulus instead of the cold stimulus.
[0032] Referring to Figure 3A, an epilating apparatus 10 comprising means for extracting
hairs from skin in the form of an epilating member 12, first means for reducing pain
in the form of a cooling member 56 and second means for reducing pain in the form
of a vibration member 60 is shown in a cross-sectional view. Again, the epilating
member 12 corresponds to the one described with reference to Figure 1. The vibration
member 60 extends out of the housing of the epilating member 12 and comprises a row
of pins 61 arranged parallel to the rotation axis 28 of the epilating member 12.
[0033] Figure 3B shows the arrangement of the pins 61 in more detail. The pins 61 are arranged
perpendicularly to the rotation axis 28 and perpendicularly to the direction of movement
29 in order to contact the epilated skin perpendicularly. In this arrangement, the
pins 61 are fed through corresponding holes in the active surface 58 of the cooling
member 56, which is connected to the epilating member 12 by any suitable contacting
means 64.
[0034] Figure 3C shows schematically the arrangement of the active surfaces 14, 58, 62 of
the epilation member 12, the cooling means 56 and the vibration means 60 as well as
the complementary matching of the surfaces 58, 62.
[0035] In operation, the epilating apparatus 10 in accordance with Figures 3A-3C is brought
into close contact with the skin to be epilated. Thereby the active surfaces 14, 58,
62 touch the skin. When the epilating apparatus 10 is moved along its direction of
movement 29 , the epilation process is visible and can be monitored by the user. Immediately
after the epilation process, the vibration member 60 contacts the epilated skin portion
with its active surface 62. The frequent exertion of pressure to the skin excites
the pressure receptors in the skin and releases the first pain masking signals. In
a closed temporal and local constellation, the skin is also cooled by the active surface
58 of the cooling member. This applies the second stimulus, i.e. cold, to the already
epilated skin and adds coldness information to the vibration information. This enhances
the pain masking effect significantly. Furthermore, this embodiment provides the benefit
of two separate members for two different stimuli, namely cold and vibration, enabling
a separate optimization for the two different members. At the same time, the two different
stimuli are applied to approximately the same skin portion, which improves the pain
masking results.
[0036] Referring to Figure 4A, an epilating apparatus 10 is shown comprising a detachable
cooling member 76 forming first means for reducing pain, an epilating member 12 as
discussed above, providing means for extracting hairs from skin, and a vibration member
80 forming second means for reducing pain. The cooling member 76 includes a housing
77 and an active surface 78. In this embodiment, the vibration head 83 is equipped
with pyramidal projections forming the active surface 82. The overall active surface
82 forms a concave surface adapted to a typical convex surface of a human body.
[0037] Figure 4B shows the epilating apparatus 10 with the cooling member 76 being detached.
The cooling member 76 can be attached to the body of the epilating member 12 by means
of a connection member 79 enabling a rigid and detachable connection. The epilation
member 12 includes the vibration member 80 comprising a vibration head 80 with active
surfaces 82.
[0038] Figure 4C shows schematically the arrangement of the active surfaces 14, 82, 78 of
the epilation member 12, the vibration member 80, and the cooling member 76. The vibration
means 80 is arranged between the epilating member 12 and the cooling member 76. Both
means for reducing pain 80, 76 are arranged behind the epilating means 12 relative
to the preferred direction of movement 29 during operation .
[0039] In operation, the active surfaces 14, 78, 82 contact the skin to be epilated, as
described above. The vibration member 80 performs movements at least partially perpendicularly
to the skin surface. Thereby, a first pain masking effect is evoked by exciting the
pressure receptors in the skin. Afterwards, the cooling surface 78 touches the already
epilated and massaged skin and adds the second pain masking stimulus: coldness. The
protrusions of the active surface 82 of the vibration member 80 enhance the application
of pressure to the epilated skin. The cooling member 76 can be detached from the body
of the epilated member 12 and moved to a cool place, e.g. a cold storage, for recharging
the cold source inside the cooling member 76.
[0040] Referring to Figure 5A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating member 12, first means for reducing pain
in the form of a cooling member 16 and second means for reducing pain in the form
of a heating member 104. The epilating member 12 and the cooling member 16 have already
been discussed in detail above in connection with Figure 1. The heating member 104
comprises a heating plate 110 with an active surface 106 for contacting the skin portion
to be epilated.
[0041] Figure 5B shows an exploded view of the epilating apparatus 10, in particular of
the heating member 104. The heat source for the heating member 104 is provided by
a resistor 108. Alternatively, the resistor 108 can be a PTC. In the assembled condition,
the resistor 108 is in close contact with the heating plate 110. This provides a good
heat transfer between the resistor 108 and the heating surface 106 for contacting
the skin portion to be epilated. In a further preferred embodiment, the heating plate
110 is connected to the epilation member 12 in such a manner that it is possible to
swivel the heating plate 110 with respect to the epilation member 12. Thereby, the
contact between the skin and the active surfaces may be improved.
[0042] Figure 5C shows schematically the arrangement of the active surface 106 of the heating
member 106 in front of the active surface 14 of the epilation member 12 as well as
the arrangement of the active surface 18 of the cooling member 16 behind the active
surface 14 of the epilation member 12.
[0043] In operation, the epilating apparatus 10 contacts the skin to be epilated by means
of its active surfaces 106, 14, 18. In this embodiment, the two pain reducing stimuli
are heat and cold. The first stimulus, i.e. heat, is applied to the skin before the
epilating process occurs. This pre-warming of the skin exerts a relaxation effect,
so that easier hair removal can take place. The heat generated by the resistor 108
is transferred via the heating plate 110 to the active heating surface 106. The heat
is transferred to the skin by the close contact between the active surface 108 and
the surface of the skin. It has been found that a temperature range between 35 and
60 °C, in particular between 40 and 50 °C, is suitable for obtaining a pain reduction
effect. After the pre-warming and relaxation of the skin portion contacting the active
surface 106 of the heating member 104, the skin portion gets into contact with the
epilating member 12 by moving the epilating apparatus 10 along its preferred direction
of movement 29. After epilation, the skin is cooled by the active cooling surface
18, as already described above. The advantages of this embodiment are a reduced number
of moving parts, the pre-warming of the skin, which is important in particular in
the case of several epilating runs, and the presence of two contrary positive sensations,
namely cold and heat.
[0044] Referring to Figure 6A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating member 12, first means for reducing pain
in the form of a cooling member 16 and second means for reducing pain in the form
of a heating member 128. The heating member 128 comprises a bracket 125 on which a
plurality of cylindrical heating elements 127 is rotatably arranged. The cylindrical
heating elements 127 together provide an active surface 124 for contacting a skin
portion. Preferably, the heating elements 127 are heated via the bracket 125. The
epilating member 12 and the cooling member 16 are configured and connected as already
discussed above with reference to Figure 1.
[0045] Figure 6B shows schematically the arrangement of the active surfaces 124, 14, 18
of the epilating apparatus 10. The active heating surface 124 is arranged in front
of the active epilating surface 14. The active cooling surface 18 is arranged behind
the active epilating surface 14 relative to the preferred direction of movement 29
during operation.
[0046] In operation, the epilating apparatus 10 is moved along its preferred operating direction
29, as already discussed above. In this particular embodiment, the heating element
128 transfers the generated heat via its active surface 124 to the skin portion to
be epilated. The cylindrical design of the heating element 128 assures smooth movement
of the apparatus and allows for good heat contact between the active surface 124 and
the surface of the skin. Further advantages arising from said pre-warming and from
the presence of contrary sensations have already been discussed above. It may also
be preferred that the heating element 128 is inclinably attached to the epilating
member 12, providing a constant contact pressure between the active heating surface
124 and the surface of the skin portion to be epilated.
[0047] Referring to Figure 7A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating element 12, first means for reducing pain
in the form of a cooling element 136 and second means for reducing pain in the form
of a heating element 144. The heating member 144 comprises an active heating surface
146 and the cooling member 136 comprises an active cooling surface 138. The heating
surface 146 is arranged in front of the epilating member 12 already described above.
The cooling surface 138 is arranged behind the epilating member 12 relative to the
preferred direction of movement 29 during operation. The active surfaces 146, 138
of, respectively, the heating member 144 and the cooling member 136 are designed to
embrace the active surface 14 of the epilating member 12, leaving only small gaps
133 between the two active surfaces 146, 138 having different temperatures. The temperatures
are generated by electrical means, e.g. by a single Peltier element, and are conducted
to the active surfaces 146, 138 of the heating member 134 and the cooling member 136,
respectively.
[0048] In operation, the epilating apparatus 10 is moved along the skin to be epilated,
with the active surfaces 146, 14, 138 shown in Figure 7B being in close contact with
the surface of the skin to be epilated. The advantages of these particular embodiments
result from a very compact design of the housing 131. This compact design is possible
due to the electrical generation of both the heat and the cold. The compact design
leads to easy handling of the epilating apparatus and to a lightweight construction.
The embracing of the active surface 14 of the epilating member 12 enhances the pain
masking effects described above even more, since the contrary sensations, namely heat
and cold, follow in a very close local and temporal correlation.
[0049] Referring to Figure 8A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilation member 12, first means for reducing pain
in the form of a cooling member 16 and second means for reducing pain in the form
of a vibration member 160. The vibration member 160 comprises a vibration head 161
and a Peltier element 164. The vibration member 160 is arranged in front of the epilating
member 12 described above, the cooling member 16 is arranged behind the epilating
element 12 relative to its preferred direction of movement 29 during operation. The
Peltier element 164 is arranged inside the vibration head 161 and provides a heat
source, as is also illustrated in the exploded view of Figure 8B. The vibration head
161 preferably consists of a ceramic material with good heat conducting properties.
[0050] In operation, the vibration head 161 performs movements at least partially perpendicular
to the axis 28 of the epilating member 12 and perpendicular to the preferred direction
of movement 29, i.e. perpendicular to the surface of the skin to be epilated. Additionally,
the vibration head 161, particularly the active surface 162 thereof, is heated by
the Peltier element 164. Thereby, this particular embodiment enables the application
of three different stimuli to the skin to be epilated. Two stimuli, namely heat and
vibration, are applied by the heated vibration head 161 before the epilating process
takes place. This allows for significant pain masking of the skin region to be epilated
before the pain receptors in the skin are excited. After the epilating process the
active surface 18 of the cooling member 16 adds the third pain masking stimulus: cold.
Alternatively, the vibration head 161 can also be cooled with a different Peltier
element 164, or cold generated by the Peltier element 164 is used for this purpose.
[0051] Referring to Figure 9A, an epilating apparatus 10 is shown comprising means for extracting
hairs from skin in the form of an epilating member 12 and first and second means for
reducing pain in the form of a cylindrical massage/vibration member 178 which, besides
applying massages/vibrations, can also transfer heat or cold to the skin. The massage/vibration
member 178 is arranged with its rotational axis parallel to the axis 28 (Figures 9B,
9C and 9D) of the epilating member 12. The cylindrical massage/vibration member 178
comprises small pin-like protrusions 176 and/or ribs for enhancing vibration. It is
possible that the massage/vibration member 178 can be cooled for providing the cold
stimulus to the skin. It is therefore preferably detachable from the epilating member
12 and can be charged in a cold source 182. Additionally, or alternatively, the massage/vibration
member 178 can be brought to an increased temperature for providing the heat stimulus
to the skin to be epilated. The detached massage/vibration element 178 can, for this
purpose, be placed in a microwave, an oven, heated water or the like. While in Figure
9A there is shown an epilating apparatus comprising only one massage/vibration member
178, it is also possible to provide two or more of such members, arranged on one or
both sides of the epilating member 12. In Figures 9B - 9D, several possible arrangements
are shown. In Figure 9B, one massage/vibration member 178 is placed behind the epilation
member 12 relative to its preferred direction of movement 29 during operation, which
massage/vibration member 178 can apply heat and/or cold to the skin, depending on
its charge state. In Figure 9C, two vibration/massagemembers 178 are arranged parallel
to the axis 28 of the epilating member 12. One massage/vibration member 178 adapted
to apply heat is arranged in front of the epilating member 12. Another massage/vibration
member 178 adapted to apply cold is placed behind the epilating member 12. In Figure
9D, a single massage/vibration member 178 adapted to apply heat is placed in front
of the epilating member 12. The massage/vibration member 178 preferably is suitable
to store heat and cold. However, it is also possible that for storing heat and cold
there are provided different massage/vibration members 178, optimized accordingly.
[0052] In operation, the epilating apparatus 10 is moved over the skin to be epilated, as
described above. At the same time, the massage/vibration member 178 is rotated and
applies the vibration stimulus, especially via the small protrusions 176. At the same
time at least one temperature different to that of the skin is applied. This particular
embodiment provides the advantages of a simple and cost-effective combination of a
cooling/warming member with a vibration member, without needing any drive or active
heating/cooling means. Furthermore, this embodiment provides a very flexible arrangement
of the different stimuli.
