Description

Dehairing instrument

Technical Field

The specification relates to the technical field of skin care, and in particular relates to a depilatory instrument.

Background

The use of epilators is increasingly chosen by the user due to the rapidity and efficiency with which the epilators remove unwanted hair from the body.

The principle of dehairing of the household dehairing instrument is that the principle of photo-pyrolysis of strong pulse light is utilized, and the melanocytes in hair follicles can selectively absorb light in specific wave bands. While the depilatory device emits intense pulsed light (Intense Pulse Light, IPL) capable of penetrating the epidermis directly into the hair follicles of the dermis. So that the hair follicle is destroyed, and the destroyed hair follicle naturally falls off after a period of time, thereby delaying or even stopping the hair growth in a short period of time.

Therefore, under the limitation that the power and the working voltage of the light emitted by the depilatory device are limited by the volume of the depilatory device, enabling more IPL light to reach hair follicles of skin of a human body as much as possible is a necessary means for improving the depilatory efficiency. However, in actual use of the epilator, there occurs a phenomenon that the air inside the epilator is liquefied into mist due to the high temperature inside the epilator and adheres to the surface of the light-emitting structure inside the epilator, and this phenomenon weakens the intensity of IPL reaching the surface of the skin of the human body, and the light loss rate increases.

The present application is described in detail below by way of specific examples:

the dehairing principle of the dehairing instrument is that the dehairing principle of strong pulse light is utilized, and the melanocytes in the hair follicle can selectively absorb the light of a specific wave band. Whereas the depilatory device emits IPL light that is able to penetrate the epidermis directly into the hair follicles of the dermis. Thus, the light energy is absorbed by melanocytes in the hair follicle within the dermis and converted to heat energy, raising the temperature of the hair follicle. When the temperature of the hair follicle rises to be high enough, the hair follicle structure is irreversibly destroyed, and the destroyed hair follicle naturally falls off after a period of time, so that the hair growth is delayed or even stopped in a short period of time.

The luminescence principle of the dehairing instrument is as follows: the capacitor is connected with the power supply to charge the capacitor, when the capacitor is charged to reach a preset value, the electric energy in the capacitor is boosted and released through the boosting effect of the transformer, the instantaneous voltage of the circuit can reach several kilovolts, and then the pulse lamp is excited to instantly release strong pulse light, so that the primary light emission is completed.

The volume and the power supply of the depilatory device are limited to different degrees, so that the intensity of IPL light reaching the skin surface of a human body is improved under the condition that the volume and the power supply cannot be optimized, namely the utilization rate of the light is improved, and the depilatory device is a desirable means for improving the depilatory efficiency.

As an example, fig. 4 shows a schematic exploded view of a part of the structure of a dehairing instrument according to an embodiment of the present application. Fig. 5 shows a partial structural cross-section of a depilating apparatus provided in accordance with an embodiment of the present application. A refrigerating member 300 is provided in the torso case 140, and the refrigerating member 300 is in contact with the cold compress 200. The cooling member 300 is attached to a partial region of the light incident surface 220 of the cold pack 200, so as to cool the cold pack 200. As shown in fig. 5, the light incident surface 220 of the cold pack 200 includes a light transmitting region 221 and an annular attachment region 222, and in fig. 4 and 5, the annular attachment region 222 surrounds the light transmitting region 221.

There are many ways in which the cold face 320 may be attached to the annular attachment region 222. Specifically, in some embodiments, the cold face 320 and the annular attachment region 222 are combined by bonding, and the cold face 320 and the annular attachment region 222 are bonded by a thermally conductive paste. After the depilating apparatus is started to operate by applying an external voltage, the refrigerating member 300 is started to operate, and the cold face 320 is attached to the cold compress member 200, so that the cold compress member 200 can be ensured to be continuously cooled. The cold pack 200 is in contact with the skin of the user in a low temperature state, thereby being capable of relieving the burning sensation and the stinging sensation of hair follicles accompanying the process of converting light energy into heat energy.

The cooling member 300 also generates heat during the cooling process, in order to conduct out the heat generated by the cooling member 300, the heat conducting member 400 is attached to the side, far away from the cold compress member 200, of the cooling member 300, and the heat conducting member 400 conducts heat to the cooling member 300 to keep the cooling member 300 working normally, so that the cold compress member 200 is continuously cooled. In some embodiments, the heat-conducting member 400 is annular and is attached to the cooling member 300. The heat conductive member 400 is attached to the hot surface 340 of the cooling member 300.

In some embodiments, a light emitting assembly 600 is further disposed inside the trunk housing 140 of the housing assembly 100 for emitting the target light. As shown in fig. 4 and 5, the light emitting assembly mainly includes a light source 620 and a light reflecting member 640. The light source 620 is configured to emit a target light. In some embodiments, the light source 620 may be an IPL generator, and the IPL has a wavelength of about 500 nm to about 1200nm. In some embodiments, the light source 620 may be a wired or non-wired light source. In some embodiments, the light source 620 may also be a laser assembly that emits light waves in a specific wavelength band to the skin surface. And a reflecting member 640 disposed at a side of the light source 620 away from the light outlet 121, for reflecting the portion of the target light irradiated to the reflecting member 640 toward the light outlet 240. The reflecting member 640 is a mirror surface on a side facing the light outlet 121, and is configured to reflect the received light to a preset direction. The shape of the mirror surface is at least one of a parabolic column and a semi-column, and the structure can enable the light received by the reflecting piece 640 to reflect towards the light-emitting surface 240 as much as possible, so that the light utilization rate is improved. In some embodiments, reflector 640 is one of a reflector cup or a reflector.

In operation, the light emitting assembly 600 generates a large amount of heat when the light source 620 emits intense pulsed light, and thus, the light emitting assembly 600 cannot directly contact the cold compress 200. Meanwhile, in the working state, the heat conducting member 400 conducts the heat of the refrigerating member 300, so that the heat conducting member 400 is kept at a higher temperature, and the light emitting assembly 600 is also kept at a higher temperature due to the light emission, so that the heat conducting member 400 cannot be in direct contact with the light emitting assembly 600, and the heat of the light emitting assembly 600 is prevented from being transferred to the heat conducting member 400 in a heat transfer manner, so that the temperature of the heat conducting member 400 is increased, and the heat conduction of the heat conducting member 400 to the refrigerating member 300 is affected.

The separator 500 is disposed at the light incident surface 220 of the cold compress 200. One end of the spacer 500 abuts against the cold compress, and one end abuts against the light emitting module 600. One end of the spacer 500 abuts against the light incident surface 220 of the cold compress 200, passes through a first annular hole surrounded by the cooling element 300, and abuts against the light emitting component 600 after passing through a second annular hole surrounded by the heat conducting element 400. The shape and the size of the first annular hole surrounded by the cooling member 300 and the second annular hole surrounded by the heat conducting member 400 may be the same, so that the cold compress member 200 and the cooling member 300 are attached more fully, the cooling member 300 and the heat conducting member 400 are attached more fully, the contact area of the cold compress member 200 and the cooling member 300 is increased, the contact area of the cooling member 300 and the heat conducting member 400 is increased, and the cooling effect is enhanced. The shape and size of the first and second annular holes are matched with the shape and size of the spacer 500, so that space waste caused by mismatching of the sizes is avoided, and assembly compactness can be ensured. In some embodiments, referring to fig. 4, the first annular hole surrounded by the cooling member 300 is the same shape and size as the second annular hole surrounded by the heat conducting member 400, and are both rectangular holes. The spacer 500 has a structure of a quadrangular prism matched with the rectangular hole, so that the spacer 500 is not easy to rotate after passing through the rectangular hole surrounded by the refrigerating piece 300 and the heat conducting piece 400, and the stability of the structure between the components is ensured.

In some embodiments, the first annular hole surrounded by the cooling member 300 is the same shape and size as the second annular hole surrounded by the heat conducting member 400, and is a circular hole. The spacer 500 has a cylindrical structure matched with the rectangular hole.

The spacer 500 is made of a light-transmitting material and is of a solid structure. The material of the spacer also has physical properties of low thermal conductivity. The spacer 500 is made of a light-transmitting material. After the light source 620 in the light emitting module 600 emits the target light, the target light sequentially passes through the spacer 500 and the cold compress 200 and then exits the epilator. The light-transmitting material comprises one of sapphire, transparent solid glass, crystal and the like. The spacer 500 is made of one of sapphire, transparent solid glass, crystal, and the like. The materials are all light-transmitting materials and can be made into solid structures, so that the light propagation is not affected, and the effect of reducing the light loss rate can be achieved. The spacer 700 is a solid structure, so that the problem that the light incident on the light incident surface 200 is affected by the water mist and cannot completely pass through the cold compress 200 to reach the user surface due to the water mist formed on the light incident surface 220 of the cold compress 200 because the air existing between the light emitting component 600 and the cold compress 200 is liquefied due to the excessive temperature difference between the two is reduced or avoided.

In some embodiments, the separator 500 and the cold compress 200 are integrally formed, i.e., the separator 500 and the cold compress 200 are made of the same material, i.e., the same material is formed by a cutting process or an injection molding process. For example: when the material of the cold compress 200 is sapphire, the material of the spacer 500 is also sapphire; when the material of the cold compress 200 is transparent solid glass, the material of the spacer 500 is also transparent solid glass; when the material of the cold pack 200 is crystal, the material of the separator 500 is also crystal. The separator 500 is the same material as the cold compress 200.

Referring to fig. 6A to 6B, the first annular hole surrounded by the cooling member 300 has the same shape and size as the second annular hole surrounded by the heat conducting member 400, and is a rectangular hole. The spacer 500 is a prismatic structure that mates with the rectangular aperture. Referring to fig. 6C to CD, the first annular hole surrounded by the cooling member 300 has the same shape and size as the second annular hole surrounded by the heat conducting member 400, and are circular holes. The spacer 500 has a cylindrical structure matched with the circular hole. The integrated structure of the separator 500 and the cold compress 200 ensures that the separator 500 and the cold compress 20 are combined more firmly and compactly, and looseness is avoided.

In some embodiments, the separator 500 and the cold compress 200 are in a detachable structure, i.e., the separator 500 and the cold compress 200 are in a combined structure. The material of the separator 500 may be the same as or different from that of the cold compress 200. For example: when the material of the cold compress 200 is sapphire, the material of the spacer 500 may be sapphire, transparent solid glass, crystal, or the like. In some embodiments, the spacer 500 is connected to the cold compress 200 by a hook and a slot adapted to the hook. For example, the light incident surface 220 of the cold pack 200 is provided with a hook, and a surface of the spacer 500 abutting against the cold pack 200 is provided with a clamping groove, and when the cold pack 200 is detached, the hook is only required to be removed from the clamping groove of the spacer 500. The light incident surface of the cold compress 200 may be provided with a plurality of hooks or clamping grooves, and the corresponding position of the surface of the separator, which abuts against the cold compress, is provided with a matched clamping groove or hook. In some embodiments, the cold compress 200 and the spacer 500 are detachable by magnetic attraction. The inner part of the cold compress 200 near the light incident surface 220 is embedded with a first magnetic member. The second magnetic member is embedded in a surface of the spacer 500 abutting the cold compress 200. The cold compress 200 and the separator 500 are combined by magnetic attraction, and meanwhile, the cold compress 200 and the separator 500 can be separated only by overcoming the magnetic attraction. The cold compress 200 and the spacer 500 are in a detachable structure, and the use of one component is not affected when the other component is updated or maintained.

In some embodiments, the spacer 500 and the cold compress 200 are bonded by a photosensitive adhesive, and the light incident surface 220 of the cold compress 200 is bonded to the side of the spacer 500 adjacent to the cold compress 200 by the photosensitive adhesive. The photosensitive paste may be bonded to the light-transmitting material. The material of the separator 500 may be the same as or different from that of the cold compress 200. Referring to fig. 7, the spacer 500 and the cold pack 200 of fig. 7 are separately manufactured and adhered to each other by a photosensitive paste applied at the position of the dotted line of fig. 7. The spacer 500 and the cold compress 200 are adhered by the photosensitive adhesive to complete the connection of the components, and the realization mode is simple and the operability is strong.

One end of the spacer 500 contacts with the cold compress 200, passes through the annular hole formed by the refrigerating member 300 attached to the cold compress 200 and the annular hole formed by the heat conducting member 400 contacting with the refrigerating member 300, and then extends out of the annular hole formed by the heat conducting member 400, one end far away from the cold compress 200 is abutted against the light emitting assembly 600, and the thickness of the spacer 500 along the light path direction is greater than the sum of the thickness of the annular hole formed by the refrigerating member 300 and the thickness of the annular hole formed by the heat conducting member 400, so as to separate the light emitting assembly 600 from the heat conducting member 400. One end of the spacer 500 away from the cold compress 200 is abutted against the light reflecting member 640 in the light emitting assembly 600, and the periphery of the cup mouth of the light reflecting member 640 is fixed on the spacer 500 by bonding. In some embodiments, the spacer 500 is bonded to the reflector 640 by silicone rubber, which is resistant to high temperatures and heat radiation.

In some embodiments, the epilator 001 may further comprise a filter 700, as shown in fig. 4, the filter 700 being disposed between the light emitting assembly 600 and the spacer 500, the filter 700 being connected to an end of the spacer 500 remote from the cold compress. The filter 700 is used to filter out light (e.g., ultraviolet light) harmful to human bodies among the strong pulse light. In some embodiments, the filter 700 may be a hard sheet-like filter, and is adhered and fixed to the end of the spacer 500 near the light reflecting member 640, and the shape and size of the area formed by the adhesion of the light reflecting member 640 and the spacer 500 are consistent with the shape and size of the filter, so as to ensure that all the light harmful to human body can be filtered. In some embodiments, the optical filter 700 may be an optical filter formed at one end of the spacer adjacent to the light reflecting member 640 through a thin film manufacturing process; or the film formed by the film preparation process is adhered to one end of the isolating piece close to the light reflecting piece 640, and the shape and the size of the area formed by adhering the light reflecting piece 640 and the isolating piece 500 are consistent with those of the filter film, so that all light harmful to human bodies can be filtered.

In some embodiments, the epilating apparatus 001 further comprises a heat dissipation component, the heat dissipation component is disposed in the body case 140 of the case component 001, and the heat dissipation component is thermally coupled with the heat conducting member 400, that is, heat of the cooling member 300 received by the heat conducting member 400 is dissipated through the heat dissipation component and the heat dissipation air port 1421 through the heat conducting connection, so as to avoid an excessive internal temperature when the epilating apparatus is in operation. In some embodiments, the heat dissipating assembly includes a heat dissipating member and a blower member. The heat sink is thermally coupled to the heat conductive member 400 to transfer heat from the heat conductive member 400 to the heat sink. The air supply piece is used for generating heat dissipation air, and the heat on the heat dissipation piece is brought to the heat dissipation air port 1421 on the depilating apparatus shell through the heat dissipation air, so that the effect of heat dissipation of the depilating apparatus 001 is achieved.

In some embodiments, the epilator 001 further comprises a power supply assembly provided inside the housing assembly 100 for supplying power to the light emitting assembly 600 and/or the heat dissipating assembly to keep working properly.

In summary, the housing assembly 100 of the epilator 001 houses the cold pack 200, the cooling plate 300, the heat conducting member 400, the spacer 500, and the light emitting assembly 600. When the dehairing instrument 001 works, the light source 620 in the light emitting assembly 600 emits target light, part of the light emitted to the light reflecting member 640 passes through the mirror surface inside of the light reflecting cup to adjust the light path and reflect the target light to a preset direction, the target light firstly passes through the filter 700 attached to the spacer 500 and close to one end of the light emitting assembly 600, the light harmful to human body is filtered, the filtered light passes through the spacer 500 and reaches the light inlet surface 220 of the cold compress 200, then passes through the cold compress 200 and then is emitted out of the light outlet surface 240 of the cold compress 200, and reaches the skin of a user, and the light outlet surface 240 is attached to the skin of the user, so that dehairing is realized. Since the cold compress 200 is kept in a low temperature state during operation, the cooling element 300 is attached to the light incident surface of the cold compress 200, the cold surface 320 of the cooling element 300 is attached to the cold compress 200, the hot surface 340 of the cooling element 300 is attached to the heat conducting element 400, and after the heat conducting element 400 transfers the heat generated during operation of the cooling element 300 to the heat dissipating assembly, the heat dissipating assembly discharges the heat to the outside of the epilator.

In order to solve the problem that the light incident on the light incident surface 200 is affected by the water mist, and cannot completely penetrate the cold compress 200 to reach the surface of the user, and the light utilization efficiency is reduced, the spacer 500 is of a solid structure and is attached to the light incident surface of the cold compress 200 because the light emergent assembly 600 and the cold compress 200 are too much in temperature difference to cause air liquefaction between the two, and water mist is formed on the light incident surface 220 of the cold compress 200. Meanwhile, the end of the spacer 500 away from the cold compress 200 is abutted against the light reflecting member 640 of the light emitting module 600 to separate the light emitting module 600 from the heat conducting member, and the two members are not in contact with each other.
