Description

Multifunctional heat conducting piece and skin treater

Technical Field

The application relates to the technical field of skin care equipment, in particular to a multifunctional heat conduction piece and a skin processor.

Background

At present, with the development of society, people pay more attention to the beauty treatment and care of skin. A variety of devices for skin care have been created. Such as depilatory instruments, skin rejuvenation instruments, wrinkle removal instruments, etc.

The basic principle of the instrument is to irradiate different kinds of target light to human skin to realize different skin care functions. For example, the dehairing principle of the dehairing instrument is that the dehairing principle of strong pulse light is utilized, and the strong pulse light (intense pulsed light, IPL) or pulse strong light is a broad spectrum light formed by focusing and filtering a light source with high intensity. Since melanocytes in hair follicles can selectively absorb light of a specific wavelength band. Whereas IPL light emitted by the epilator 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. During this process, the user may feel a burning sensation to the skin. Thus, providing a cold compress at the light exit of the epilator may reduce this burning sensation. Also, in other skin treatments, heat application to the skin is required while phototherapy is being performed to open pores and make the irradiation depth of the target light deeper. In this case, a hot compress member is required to be arranged at the light outlet of the depilating apparatus. For convenience of description, the above-described cold and hot packs are collectively referred to as a heat conductive member, i.e., a heat conductive member. The cold compress piece is used for guiding out heat of human skin, and the hot compress piece is used for guiding in heat to human skin.

However, the heat conductive member of the prior art has a single function and has no effect other than cold compress and hot compress. When other auxiliary functions are required to be provided on the skin treater, in order to prevent light blocking, the relevant functional parts can only be provided avoiding the heat conducting member, thereby making the size of the skin treater larger and the portability lower.

These and other features of the present specification, as well as the operation and function of the related elements of structure, as well as the combination of parts and economies of manufacture, may be significantly improved upon in view of the following description. All of which form a part of this specification, reference is made to the accompanying drawings. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the description. It should also be understood that the drawings are not drawn to scale.

Currently, skin processors are of a wide variety and are divided into functional groups, and skin processors generally include dehairing instruments, skin tendering instruments, wrinkle removing instruments, whitening instruments, and the like. The present application will be described below with reference to a depilatory device, and other skin treatment devices such as a skin care device, a whitening device, a skin rejuvenation device, etc. may be considered similarly.

The dehairing principle of the dehairing instrument is that the light pyrolysis principle of strong pulse light is utilized, the strong pulse light (intense pulsed light, IPL) or pulse strong light is a broad spectrum light formed by focusing and filtering a light source with high intensity, and the dehairing principle is incoherent ordinary light rather than laser. The IPL wavelength is 500-1200 nm. Since melanocytes in hair follicles can selectively absorb light of a specific wavelength 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, the transformer is used for boosting voltage to charge the capacitor, when the capacitor is charged to reach a preset value, and the controller receives a trigger signal, electric energy in the capacitor is released, the instantaneous voltage can reach hundreds of volts, and then the pulse lamp is excited to instantly release strong pulse light, so that the primary light emission is completed.

The light source for the dehairing instrument to emit light is a pulse lamp, and a reflecting piece is arranged outside the light source in order to gather the light emitted by the light source. The light source emits strong pulse light after being electrified; the light reflecting piece is arranged around the light source and is used for reflecting the strong pulse light emitted by the light source to a preset light emitting direction. The optical filter is arranged on the light-emitting light path of the light source and is used for filtering out light (such as ultraviolet light) harmful to human bodies in the strong pulse light. The dehairing light filtered out harmful light acts on human skin, can penetrate through epidermis to directly reach into hair follicle of dermis and be absorbed by melanocyte in hair follicle, thereby raising hair follicle temperature, destroying hair follicle structure and achieving the effect of inhibiting hair growth.

Since hair follicles can feel burning sensation to the skin during the rise in temperature of light energy, cold dressings are provided in depilatories to reduce or even eliminate such burning sensation. The cold compress piece is in direct contact with human skin to cool the surface of the skin, so that the skin is cooled, and the burning or pain caused by the temperature rise of hair follicles can be reduced or even eliminated.

However, when other auxiliary functions are required to be provided on the skin treater, only relevant functional parts can be provided to avoid the cold compress in order to prevent light blocking, thereby making the skin treater bulky and reducing portability.

In view of this, the embodiments of the present application can integrate the auxiliary functions on the heat conductive member, thereby increasing the functions of the skin treater without increasing the volume of the skin treater.

As shown in fig. 1 and 2, the embodiment of the present application provides a multifunctional heat conducting member 100 for a skin treatment device, where the multifunctional heat conducting member 100 includes a heat conducting member body 110 and an electrode 120, and the heat conducting member body 110 is a light-transmitting member and includes a light incident surface (not shown in the drawing) and a light emitting surface 111 opposite to the light incident surface, and the light emitting surface 111 is used for contacting with skin of a human body. The electrode 120 is formed on a partial area of the light emitting surface 111 and is a light-transmitting conductive member, and the electrode 120 is used for electrically stimulating the human skin.

The multifunctional heat conducting member 100 according to the embodiment of the present application integrates the electrode 120 on the heat conducting member body 110, and the electrode 120 can be used for electrically stimulating the skin of the human body. Different kinds of electrical stimulation can achieve different skin care effects, so that various skin care functions can be integrated on the heat conducting piece. And because the electrode 120 is made of a light-transmitting conductive material and is formed only on a partial area of the light-emitting surface 111, the electrode 120 does not block the emission of the target light, and the rest of the light-emitting surface 111, where the electrode 120 is not arranged, can still be in direct contact with the skin of the human body to conduct heat, and the electrode 120 can also have a certain heat conduction function when contacting with the skin of the human body. Thereby ensuring the cold compress or hot compress effect of the heat conducting piece.

It should be noted that, the heat conducting member may be a cold compress member or a hot compress member, and when the heat conducting member is a cold compress member, the cold compress member may be used to cool the skin of a human body, so as to alleviate or relieve the burning sensation and pain when using the phototherapy skin treatment device such as a depilatory device. The hot compress piece can be used for carrying out hot compress to human skin for the pore of human skin expands and opens, thereby makes the irradiation depth of target light deeper, and the effect is better. Or to allow more efficient penetration of the lotion into the skin.

There are various implementations of the electrode 120, for example, the electrode 120 may be a pulse electrode capable of emitting a pulse current to human skin. While the pulsed current may be TENS (Transcutaneous Electrical Nerve Stimulation ) pulsed current or EMS (Electrical muscle stimulation, muscle electrical pulse stimulation) pulsed current. Wherein, TENS pulse current can stimulate the sensory nerve through mild and trace current to block the transmission of pain nerve signals, thereby achieving the effect of pain relief. For example, can be applied to depilatory instruments to relieve pain or burning sensation from IPL bands. The EMS pulse current can stimulate the formation of muscle and lymph, and can shrink the muscle, thereby achieving the effects of removing edema and lifting tension to cause skin.

In addition, the electrode 120 may be a Radio Frequency electrode capable of emitting Radio Frequency (RF) waves toward the skin of the human body. The RF wave is a high-frequency alternating electromagnetic wave, which can directly penetrate the skin, and can generate strong resonance rotation (in the order of millions of times per second) by utilizing the impedance effect formed by the skin to generate heat energy so as to achieve the purposes of heating collagen tissues and heating fat cells, so that the temperature of the bottom layer of the skin is instantaneously increased, and immediate collagen tightening and collagen regeneration are generated by the stimulation of the dermis.

It should be noted that the rf electrode may be a single rf electrode or a dual rf electrode. When the radio frequency electrode is a dual radio frequency electrode, the dual radio frequency electrode comprises a positive electrode radio frequency electrode and a negative electrode radio frequency electrode. The number of the double radio-frequency electrodes can be one pair of positive and negative radio-frequency electrodes, or a plurality of pairs of positive and negative radio-frequency electrodes.

The material, number, shape and arrangement of the electrodes 120 may be selected in various ways. As shown in fig. 3, in one implementation, the electrode 120 may include a plurality of electrodes 120, and the plurality of electrodes 120 are spaced apart from each other on the light emitting surface 111. Therefore, the multi-point electric stimulation can be simultaneously carried out on the skin of the human body, so that the range of the electric stimulation is enlarged.

The plurality of electrodes 120 may be distributed at intervals or may be arranged next to each other on the light-emitting surface 111. When the plurality of electrodes 120 are distributed on the light emitting surface 111 at intervals, the stimulating current emitted by the electrodes 120 is not interfered by the adjacent electrodes, so that the respective control of the electrodes is facilitated.

The plurality of electrodes 120 may be uniformly distributed or unevenly distributed. When the plurality of electrodes 120 are uniformly distributed on the light-emitting surface 111, as shown in fig. 1, the plurality of electrodes 120 are equally spaced apart from each other on the light-emitting surface 111. Thus, the plurality of electrodes 120 can be distributed more uniformly on the light-emitting surface 111, and the distribution of the electric stimulation can be more uniform, thereby improving the efficiency of the electric stimulation.

The plurality of electrodes 120 may also be arranged in an electrode array, for example, in a rectangular array as shown in fig. 1. Thus, the arrangement of the electrodes can be more orderly. There are various ways in which the plurality of electrodes 120 may form an electrode array. For example, a plurality of the electrodes 120 may be arranged in a linear shape to form a line array. Specifically, the plurality of electrodes 120 may be arranged in a straight line on the light-emitting surface 111. As shown in fig. 3, fig. 3 shows a structure in which a plurality of electrodes 120 are arranged in a straight line along the edge of the light-emitting surface 111. In addition, the plurality of electrodes 120 may be arranged in an arc or circumferentially. Whereby a smaller number of electrodes 120 may be employed to achieve a greater range of electrical stimulation.

For another example, the plurality of electrodes 120 may be arranged in a planar array. Further, the outer contour of the surface array may also be adapted to the shape of the light-emitting surface 111. Specifically, as shown in fig. 1, when the light-emitting surface 111 is rectangular, the electrode array may be provided as a rectangular surface array that conforms to the shape of the light-emitting surface 111. That is, the plurality of electrodes 120 are arranged in a plurality of rows along the longitudinal direction of the light-emitting surface 111, and are arranged in a plurality of columns along the width direction of the light-emitting surface 111. Also, when the light-emitting surface 111 is circular, the electrode array may be provided as a circular surface array that is adapted to the shape of the light-emitting surface 111. Thus, the electric stimulation function can be realized within the entire range of the light-emitting surface 111, and the effect of electric stimulation can be improved.

When the plurality of electrodes 120 are unevenly distributed on the light-emitting surface 111, the distribution density of the electrodes 120 may be set according to an actual use scene. For example, when the multifunctional cold compress is applied to phototherapy apparatuses such as a depilatory apparatus, the intensity of the target light near the center of the light-emitting surface 111 may be greater than that of the target light at the edge region of the light-emitting surface 111. Therefore, the skin near the center of the light emitting surface 111 may feel a higher pain than the pain near the edge of the light emitting surface 111. At this time, the distribution density of the plurality of electrodes 120 on the light-emitting surface 111 may be gradually reduced from the center of the light-emitting surface 111 to the edge region of the light-emitting surface 111, so that the paralyzing and pain-relieving effect of the center region of the light-emitting surface 111 may be stronger than that of the edge region of the light-emitting surface 111, and thus the electro-stimulation effect of the electrodes 120 may conform to the use scenario of the phototherapy product, thereby achieving the paralyzing and pain-relieving effect and saving the number or materials of the electrodes 120.

It should be noted that, when the multifunctional cold compress is applied to other skin treatments, the density distribution of the electrode 120 on the light emitting surface 111 can be adjusted in combination with the actual conditions of the other skin treatments and the actual requirements for electrical stimulation. For example, if the electrical stimulation effect of the edge region is required to be stronger, the distribution area of the plurality of electrodes on the light-emitting surface may be gradually increased from the center of the light-emitting surface to the edge region of the light-emitting surface.

The shape of the electrode 120 may also be selected, for example, the cross-sectional shape of the electrode 120 may include one or more of polygonal, circular, elliptical, or irregular patterns. That is, only the electrode 120 of any one of the above-described shapes may be provided on the light-emitting surface 111, or the electrode 120 of any two of the above-described shapes or the electrode 120 of a plurality of shapes may be provided at the same time. The cross section refers to a cross section parallel to the light-emitting surface 111.

In addition, as shown in fig. 4, the electrode 120 may also employ a ring electrode 120. The annular electrode 120 can cover a larger area of the light-emitting surface 111 on the premise of setting a smaller number of the electrodes 120, and the coverage of the annular electrode 120 is continuous without break points. Thereby realizing more comprehensive electric stimulation effect on human skin.

In order to maximize the electrical stimulation efficiency of the ring electrode 120, the ring electrode 120 may be disposed as close to the edge region of the light-emitting surface 111 as possible. Thus, the ring electrode 120 can be made longer in circumference and the area of the enclosed area can be made larger, thereby making the electrical stimulation more efficient when the electrical stimulation function is used.

In order to further increase the area of the area surrounded by the ring electrode 120, the ring electrode 120 may be disposed to match the shape of the light-emitting surface 111. For example, when the shape of the light-emitting surface 111 is circular, the ring electrode 120 may be provided in a circular shape. When the shape of the light-emitting surface 111 is polygonal, the ring electrode 120 may be provided as a polygonal ring or the like.

In one possible implementation, as shown in fig. 5, the ring electrode 120 may also be provided in a plurality, with the plurality of ring electrodes 120 being nested in a spaced relationship. This results in a larger coverage area of the ring electrode 120 and better electrical stimulation. When the plurality of ring electrodes 120 are disposed to be nested with each other, the plurality of ring electrodes 120 may have the same shape or may have different shapes. For example, when the light-emitting surface 111 has a rectangular shape, the ring electrode 120 of the outermost layer may be provided in a rectangular ring structure, and the ring electrode 120 of the inner layer may be provided in a rectangular ring structure or may be provided in a circular ring structure.

The plurality of ring electrodes 120 may or may not have equal widths. When the skin treatment device is a phototherapy device such as an epilator, the widths of the plurality of ring-shaped electrodes 120 gradually increase from the center of the light-emitting surface 111 to the edge region of the light-emitting surface 111. I.e., closer to the edge, the greater the width of the ring electrode 120. This allows the effect of enlarging the coverage area to be created when the electrical stimulation is performed from the middle to the edges.

In addition, the thicknesses of the plurality of annular electrodes protruding out of the light emitting surface can be the same or different. In one possible implementation manner, the thicknesses of the plurality of ring-shaped electrodes protruding from the light-emitting surface may gradually decrease from the center of the light-emitting surface to the edge region of the light-emitting surface. Thus, the ring electrode in the middle area can be sunk into the skin to a deeper depth, so that the electric stimulation effect of the middle part is better.

When the electrode 120 is disposed on the light-emitting surface 111, as shown in fig. 2 and 5, the electrode 120 may be disposed above the light-emitting surface 111, that is, the electrode 120 may be disposed protruding from the light-emitting surface 111. This arrangement is easy to implement, and the light-emitting surface 111 does not need to be machined. In addition, the electrode 120 may be embedded in the light-emitting surface 111, i.e., the outer end surface of the electrode 120 is flush with the light-emitting surface 111 or slightly lower than the light-emitting surface 111. When the outer end surface of the electrode 120 is flush with the light-emitting surface 111, the light-emitting surface 111 and the outer end surface of the electrode 120 form a complete plane, so that no concave-convex feeling is generated when the electrode contacts with skin, and the user experience is better.

When the plurality of electrodes 120 are disposed protruding from the light-emitting surface 111, the thicknesses of the plurality of electrodes 120 protruding from the light-emitting surface 111 may be equal or different. At this time, the thickness of the electrode 120 protruding from the light emitting surface 111 may be set according to different application positions of the skin treater on the human body. For example, when the skin treater is mainly applied to protruding parts (such as chin, face, arms) of a human body, the thickness of the plurality of electrodes 120 protruding from the light-emitting surface 111 may be gradually increased from the center of the light-emitting surface 111 toward the edge region of the light-emitting surface 111. At this time, the outer end surfaces of the plurality of electrodes 120 are integrally formed in a concave structure, so that it is possible to more closely fit with the convex portions of the human body, to increase the contact area with the skin of the human body. For another example, when the skin treater is mainly applied to a concave portion (such as an armpit) of a human body, the thickness of the plurality of electrodes 120 protruding out of the light emitting surface 111 may be gradually reduced from the center of the light emitting surface 111 to the edge region of the light emitting surface 111. At this time, the outer end surfaces of the plurality of electrodes 120 are integrally formed in a convex structure, so that it is possible to more closely fit with the concave portion of the human body to increase the contact area with the skin of the human body.

The electrode 120 may be made of ITO (Indium Tin Oxide) or FTO (F-doped Tin Oxide), and may be made of fluorine-doped Tin Oxide. ITO and FTO have good conductivity and light transmittance, so the electric stimulation function is realized, and meanwhile, the emission influence on target light is small.

The material of the heat conducting member body 110 may be crystalline or amorphous. For example, when the material of the heat conducting member body 110 is crystal, the material of the heat conducting member body 110 may be sapphire, ruby, emerald, quartz, crystal, or the like. When the material of the heat conducting member body 110 is amorphous, the material of the heat conducting member body 110 may be quartz glass. The materials have better heat resistance and thermal conductivity.

When the number of the electrodes 120 is plural, in order to supply power to the plural electrodes 120 at the same time, the plural electrodes 120 may be connected to the same circuit board and supplied with power through the power supply module. In addition, a printed wiring may be formed on the light-emitting surface 111, and the plurality of electrodes 120 may be electrically connected to each other via the printed wiring, and the electrically connected electrodes 120 may be supplied with power via the power supply module. Because the conductor tracks can be made thinner, the effect on the target light is less.

The multifunctional heat conductive member 100 may be provided on a main body of the skin treater or may be provided on an accessory head of the skin treater. When the multifunctional heat conductive member 100 is provided on the main body of the skin treater, the specific structure of the skin treater may be as follows:

as shown in fig. 6, the skin treater includes a housing 200, a light emitting assembly (not shown), a circuit module (not shown), and a multifunctional heat conductive member 100. Wherein, the shell 200 is provided with an outlet. The light emitting assembly is arranged in the shell and is configured to emit target light rays to the emergent opening. The multifunctional heat conductive member 100 is provided at the outlet to electrically stimulate the human skin while performing cold or hot compress on the human skin. The circuit module is used for supplying electric energy to the electrodes of the multifunctional heat-conducting member 100 so that the electrodes emit stimulating current to the skin of the human body.

The skin processor may be a depilatory device, a whitening device, a skin tendering device, and an acne removing device. Other instruments with cosmetic functions are also possible. In addition, the light emitting component may be selectively provided or not provided according to the functional requirements of the above devices, which is not limited herein.

The target Light may include at least one of IPL Light, LED Light, laser Light, OPT (Optimal Pulsed Light, perfect Pulsed Light), and DPL (Dye Pulsed Light). The IPL light can decompose abnormal pigment cells, destroy hair follicles, close abnormal blood vessels, stimulate collagen proliferation and elastic fiber rearrangement, so that the effects of removing freckles, unhairing, removing red blood filaments, whitening and tendering skin are achieved. The laser is light with accurate action and low diffusivity in radiation, so that the skin can be singly and accurately improved. For example: in eliminating freckles, the laser is directed only to melanin of the dermis and does not act on water molecules, hemoglobin or capillaries in the skin. The principle of LED skin phototherapy is as follows: by utilizing the photo-biological regulation effect, after the cells are irradiated by low-energy visible light, mitochondria of an energy plant of the cells are stimulated to generate more energy, so that biological cells are stimulated, physiological reactions are induced or enhanced, the damage of free radicals is reduced, the cells are activated, the damaged cells are repaired and a protective film is produced, and the purposes of treatment and anti-aging are achieved. The OPT photon skin tendering mainly has good improvement effect on the conditions of skin color spots, acne pits, pockmarks and rough skin. DPL photon tender skin can play fine anti-aging and remove the effect of wrinkle, but also can play effectual accuse oil effect, can promote collagen's regeneration, protect skin elasticity and vigor.

The skin treatment device may be provided with only one light source of the above-mentioned various target lights, or may be provided with two or more light sources of the above-mentioned various target lights at the same time. And are not limited thereto.

When the skin treater is the appearance that moults, the skin treater can also include refrigeration piece and radiator unit, wherein, refrigeration piece set up in on the multi-functional heat conduction piece 100, in order to right multi-functional heat conduction piece 100 cooling, radiator unit sets up on refrigeration piece for dispel the heat to refrigeration piece.

Specifically, the refrigerating element may employ a semiconductor refrigerating sheet (also called thermoelectric refrigerating sheet) including a cold face and a hot face. The refrigeration member may generate a low temperature on the cold face after energizing. The cold face is in contact with the multi-functional heat conductive member 100, thereby continuously cooling the multi-functional heat conductive member 100. The light emitting surface 111 of the multifunctional heat conducting member 100 contacts with the skin of the human body to cool the surface of the skin of the human body, so that the skin of the human body is cooled, and the burning or pain caused by the heating of the hair follicle can be reduced or even eliminated. The heat dissipation assembly specifically comprises a temperature equalizing plate and a fan, wherein the temperature equalizing plate is in contact with the hot surface of the semiconductor refrigeration piece so as to conduct out and diffuse heat of the hot surface of the semiconductor refrigeration piece. The fan is used for blowing the temperature-equalizing plate to accelerate the temperature reduction of the temperature-equalizing plate.

The electrode 120 may be formed on the heat conductive member body 110 by various methods, for example, the electrode 120 may be connected to the light emitting surface 111 by a physical connection method, specifically, by an adhesive, a clamping connection method, a screw connection method, or the like. For another example, the heat conductive member body 110 and the electrode 120 may be integrally formed. For example, the protruding electrode 120 is formed by directly processing the light emitting surface 111 of the heat conducting member body 110. For another example, a transparent conductive layer may be formed on the light-emitting surface 111, and then the electrode 120 may be formed on the transparent conductive layer. The heat conducting member body 110 and the electrode 120 are structurally stable during the integral molding, and the following describes in detail the implementation method of the integral molding of the heat conducting member body 110 and the electrode 120:

the multifunctional heat conductive member 100 may form the electrode 120 on the light emitting surface 111 of the heat conductive member body 110 through an etching process.

In one possible implementation, as shown in fig. 7, forming the electrode 120 on the light emitting surface 111 of the heat conductive member body 110 through an etching process includes the following steps:

s100, forming a light-transmitting conductive layer on the light-emitting surface 111 of the heat conducting member body 110;

and S200, etching the light-transmitting conductive layer through the etching process to form the electrode 120.

s202, exposing and developing the photoresist film through a mask plate to enable the position, corresponding to the electrode 120, on the photoresist film to be reserved to form a first pattern, and removing the rest parts, except the first pattern, on the photoresist film;

s203, etching the light-transmitting conductive layer to remove the part of the light-transmitting conductive layer which is not covered by the photoresist film;

It should be noted that, the material of the transparent conductive layer may be ITO or FTO. The light-transmitting conductive layer may be formed on the light-emitting surface 111 by one or more of a chemical deposition process, a crystal growth process, a sputtering process, and a chemical doping process.

In another possible implementation manner, the heat conducting member body may be a light-transmitting and electrically conducting member, and the forming the electrode 120 on the light-emitting surface 111 of the heat conducting member body 110 through the etching process includes the following steps:

N100, performing partial etching on the light-emitting surface 111 of the heat conducting member body 110 by using the etching process, so as to form the electrode 120.

As shown in fig. 8, the above-mentioned partially etching the light-emitting surface 111 of the heat conducting member body 110 by the etching process to form the electrode 120 includes:

n101, covering a light-emitting surface 111 of the heat-conducting member body 110 with a photoresist film;

n102, exposing and developing the photoresist film through a mask plate, so that the position, corresponding to the electrode 120, on the photoresist film is reserved to form a first pattern, and the rest part, except the first pattern, on the photoresist film is removed;

n103, etching the light-emitting surface 111 of the heat-conducting member body 110, so that a portion of the light-emitting surface 111 of the heat-conducting member body 110 not covered by the photoresist film is etched to a preset depth;

n104, removing the remaining photoresist film, so that the unetched material on the light-emitting surface 111 of the heat-conducting member body 110 protrudes from the light-emitting surface 111 to form the electrode 120.

The above method directly forms the electrode 120 on the light emitting surface 111 of the heat conducting member body 110, and the processing method is simple and does not need to use other materials, so that the overall structure of the electrode 120 and the heat conducting member body 110 is more stable. And because the electrode 120 is consistent with the material of the heat conducting piece body 110, the electrode 120 has the heat conductivity consistent with the heat conducting piece body 110, and the cold compress effect or the hot compress effect of the heat conducting piece cannot be affected because the electrode 120 is arranged.

In another possible implementation manner, as shown in fig. 9, forming the electrode 120 on the light emitting surface 111 of the heat conductive member body 110 through an etching process includes the following steps:

q100, locally etching the light-emitting surface 111 of the heat conducting member body 110 by the etching process, so that the light-emitting surface 111 of the heat conducting member body 110 is locally recessed to form a recessed portion;

and Q202, etching the light-emitting surface 111 on which the light-transmitting conductive layer is formed, and removing the part of the light-transmitting conductive layer covering the light-emitting surface 111 so as to expose the part of the light-transmitting conductive layer filled in the concave part.

The electrode 120 of the heat conducting piece manufactured by the method is embedded in the heat conducting piece body 110, so that the heat conducting piece body 110 can effectively protect the electrode 120, and the electrode 120 is not easy to collide and fall off. In addition, the contact area between the electrode 120 and the heat conducting member is larger, and the connection is more stable.
