Technical Field

The instrument can generate a large amount of heat during operation, and a heat dissipation structure is required to be arranged for heat dissipation.

For example, the principle of dehairing in a dehairing instrument on the market is to utilize the photothermolysis principle of strong pulse light, so that the strong pulse light directly reaches the hair follicle of the dermis, and the light energy is absorbed by the melanocytes in the hair follicle in the dermis and converted into heat energy, so that the temperature of the hair follicle is increased, thereby realizing the dehairing effect. Since the light source emitting the target light generates a large amount of heat and other devices inside the skin treater generate a certain amount of heat, it is necessary to radiate heat from the skin treater in order to prevent the temperature inside the skin treater from being too high.

For another example, to improve the comfort of use, a cold or hot compress function is sometimes added to the above apparatus, which also requires heat dissipation from the cold or hot compress.

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.

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

skin treater devices for caring skin of a user, currently, the variety of skin treater is very large, and the skin treater generally includes a depilatory device, a skin tenderer, a wrinkle remover, a whitening device, a cosmetic device, etc., in terms of function division. In order to facilitate understanding of the solution of the present application, the following description will take a conventional dehairing device as an example to describe the defects of the related art, and similar problems exist in other skin processors such as a skin care device, a whitening device, a skin care device, a beauty device, and the like.

For example, in the related art, the principle of dehairing of a dehairing instrument is that the principle of photo-pyrolysis 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, and the nature of the broad spectrum light is incoherent ordinary light rather than laser light. The wavelength of IPL is usually 500-1200 nm (it is understood that IPL light also can achieve skin rejuvenation, for example, when the IPL wavelength is 560-640 nm, that is, when IPL emits 560-640 nm light, the epilator is also called a skin rejuvenation device, and the epilation effect is weaker). 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 luminous 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 is a pulse lamp, and a reflecting piece is arranged outside the light source in order to gather the light rays 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.

Because hair follicles can feel glowing sensation on skin in the process of increasing the temperature of light energy, a cold compress piece and a refrigerating piece are arranged in the dehairing instrument, the refrigerating piece is used for refrigerating the cold compress piece, and the cold compress piece is directly contacted with human skin to cool the surface of the skin, so that the glowing sensation or pain caused by the temperature rise of the hair follicles can be relieved or even eliminated.

When the dehairing instrument works, the pulse lamp and the refrigerating piece can generate a large amount of heat in working engineering, and the heat can cause the temperature in the skin processor to be too high, so that the skin of a user is scalded or other components in the skin processor are burnt.

In order to solve the problem of heat dissipation, as shown in fig. 1 and 6, an embodiment of the present application provides a skin treater, which includes a housing assembly 1, and a housing air inlet 11 and a housing air outlet 12 that are in communication with an external environment are disposed on the housing assembly 1. A heat dissipation air duct 2 and a first fan 3 are arranged in the shell component 1. The heat dissipation air duct 2 is provided with an air duct air inlet 21 and an air duct air outlet, and the air duct air outlet is communicated with the shell air outlet 12. The heat dissipation air duct 2 is used for guiding the flow direction of air so that the heat dissipation air entering the shell assembly 1 flows along a preset path to dissipate heat of a target heating element in the shell assembly 1. The first fan 3 is configured to convey heat dissipation air into the air duct air inlet 21, the first fan 3 comprises a first fan outlet 31 and a first fan inlet, the first fan outlet 31 is correspondingly arranged with the air duct air inlet 21, and the first fan inlet is communicated with the shell air inlet 11. The air outlet area of the first fan outlet 31 is smaller than or equal to the air inlet area of the air duct air inlet 21.

In order to achieve the effect of increasing the air supply amount by using the bernoulli principle, an auxiliary air inlet gap 4 is formed between the periphery of the air duct air inlet 21 and the periphery of the first fan outlet 31 as shown in fig. 1, or an auxiliary air inlet gap 4 is formed at a position of the air duct wall of the heat dissipation air duct 2 close to the air duct air inlet 21 as shown in fig. 3. The auxiliary air intake gap 4 is configured to allow air outside the heat dissipation air duct 2 to be introduced into the heat dissipation air duct 2 through the auxiliary air intake gap 4 when the heat dissipation air enters the heat dissipation air duct 2.

In the skin treater provided in this embodiment, since the air outlet area of the first fan outlet 31 is smaller than or equal to the air inlet area of the air duct air inlet 21, an auxiliary air inlet gap 4 is formed. When the first fan 3 is started, the first fan 3 blows air into the heat dissipation air duct 2, so that fast-moving air flow is formed at the air duct air inlet 21, the pressure at the air duct air inlet 21 is reduced, air outside the heat dissipation air duct 2 is sucked into the heat dissipation air duct 2 through the auxiliary air inlet gap 4, and the air quantity in the heat dissipation air duct 2 is increased, that is, a bernoulli phenomenon can be formed by the structure of the auxiliary air inlet gap 4, so that the air quantity in the heat dissipation air duct 2 can be increased. Therefore, the first fan 3 with smaller power can also realize the transportation of larger air quantity, thereby ensuring the heat dissipation efficiency inside the skin processor on the premise of saving energy; or under the condition of constant power, the air quantity is increased so as to improve the heat dissipation efficiency inside the skin processor.

In some embodiments, the ratio of the air outlet area of the first fan outlet to the air inlet area of the air inlet of the air duct is greater than or equal to 0.65 and less than or equal to 0.9, such as 0.65, 0.68, 0.7, 0.73, 0.75, 0.77, 0.8, 0.83, 0.85, 0.87, or 0.9, etc. may be desirable. It can be understood that if the ratio is too small, the air supply quantity of the fan is too small, so that heat dissipation is not facilitated; if the ratio is too large, the air blown out by the fan is easy to blow out of the heat dissipation air duct, so that the generation of the Bernoulli phenomenon is affected. Illustratively, the ratio is greater than or equal to 0.75 and less than or equal to 0.85.

The auxiliary air intake gap 4 is implemented in various ways, and the following examples are respectively illustrated:

as shown in fig. 1, the first fan outlet 31 is located outside the heat dissipation air duct 2, and the first fan outlet 31 is spaced from the air duct air inlet 21. At this time, in order to form the auxiliary air intake gap 4 between the periphery of the duct air intake 21 and the periphery of the first fan outlet 31. Only a certain interval distance is required between the first fan outlet 31 and the air duct air inlet 21, the interval distance is the auxiliary air inlet gap 4, and under the influence of the bernoulli effect, the additional heat dissipation air is brought into the heat dissipation air duct 2 through the auxiliary air inlet gap 4, so that the effect of increasing the air intake is realized. The structure does not need to provide an additional ventilation opening at the air inlet section of the heat dissipation air duct 2, and the realization mode is simple.

For another example, as shown in fig. 2, the air outlet area of the first fan outlet 31 is smaller than the air inlet area of the air duct air inlet 21, and at this time, the first fan outlet 31 may extend into the heat dissipation air duct 2. Thereby, an auxiliary air intake gap 4 is formed between the inner wall of the duct air intake 21 and the outer wall of the first fan outlet 31. Under the influence of Bernoulli effect, additional heat dissipation wind is guided into the heat dissipation wind channel 2 by between the inner wall of wind channel air intake 21 and the outer wall of first fan export 31 to realize the effect of increasing the intake. According to the structure, as a part of the first fan 3 extends into the heat dissipation air duct 2, the space occupied by the first fan 3 in the air outlet direction can be reduced, and the skin processor is beneficial to realizing miniaturization.

For another example, as shown in fig. 3, a ventilation opening 22 may be further provided on a side wall of the heat dissipation air duct 2 near the first fan outlet 31, and the ventilation opening 22 forms the auxiliary air intake gap 4. At this time, the first fan outlet 31 may extend into the heat dissipation air duct 2. In addition, as shown in fig. 3, the first fan outlet 31 may be completely attached to the air duct inlet 21. The ventilation openings 22 may be provided in one or more, and when the ventilation openings 22 are provided, the ventilation openings 22 are disposed around the first fan outlet 31. The intake air volume can thereby be further increased. In this embodiment, the plurality of vents 22 may also be uniformly disposed around the first fan outlet 31, and the plurality of vents 22 may be the same size. The intake of each vent 22 is thus made substantially equal, resulting in better flow stability of the heat dissipation air.

The air introduced into the heat dissipation air duct 2 through the auxiliary air intake gap 4 may be air inside the housing assembly 1 or air outside the housing assembly 1. It is also possible to introduce air inside the housing assembly 1 and air outside the housing assembly 1 at the same time. In order to facilitate the introduction of air outside the housing assembly 1, as shown in fig. 1 to 3, an auxiliary air inlet 13 communicating with the external environment may be provided on the housing assembly, and the auxiliary air inlet 13 may be provided corresponding to the position of the auxiliary air inlet gap 4.

Under the condition that the arrangement space allows, the closer the auxiliary air inlet 13 is to the auxiliary air inlet gap 4, the more convenient the wind of the auxiliary air inlet 13 flows into the heat dissipation air duct 2 through the auxiliary air inlet gap 4, and the smaller the resistance of the wind inlet is. Of course, if the installation space is not allowed (for example, in order to avoid the hand-held portion of the skin treatment device), the auxiliary air inlet 13 and the auxiliary air inlet gap 4 may not be provided in correspondence with each other, and at this time, although the auxiliary air inlet 13 and the auxiliary air inlet gap 4 are spaced apart by a certain distance, the air supply direction of the auxiliary air inlet 13 may be set toward the auxiliary air inlet gap 4, and no other component may be provided between the auxiliary air inlet 13 and the auxiliary air inlet gap 4 as much as possible, thereby achieving the purposes of reducing the air resistance and ensuring the air intake.

The auxiliary air inlet 13 may be provided one or a plurality of. When the plurality of auxiliary air inlets 13 are provided, the plurality of auxiliary air inlets 13 are provided around the periphery of the auxiliary air inlet gap 4. The intake air volume can thereby be further increased. In this embodiment, when the auxiliary air intake gap 4 is a plurality of ventilation openings 22 shown in fig. 3, the plurality of auxiliary air intake openings 13 may also be disposed in a one-to-one correspondence with the plurality of ventilation openings 22, so that each ventilation opening 22 is correspondingly disposed with the auxiliary air intake opening 13, thereby facilitating the air outside the housing assembly 1 to enter into each ventilation opening 22.

As shown in fig. 6 to 8, the housing assembly includes a housing 14 and an inner bracket (not shown) disposed in the housing 14, the auxiliary air inlet 13, the housing air inlet 11 and the housing air outlet 12 are formed in the housing 14, and the heat dissipation air duct 2 is formed in the inner bracket; or the heat dissipation air duct 2 is formed on the shell; or a part of the heat dissipation air duct 2 is formed on the inner bracket, and the other part is formed on the outer shell.

The housing has a first side 141 and a second side 142 in the thickness direction X, and a third side 143 and a fourth side 144 in the width direction Y. The shell air inlet 11 and the auxiliary air inlet 13 may be disposed on the same side of the shell 14, or may be disposed on different sides of the shell 14.

For example, when a case air inlet is formed at the first side 141, a case air outlet 12 may be formed at the first side 141 and/or the third side 143, and an auxiliary air inlet 13 may be formed at the second side 142 and/or the fourth side 144.

Specifically, as shown in fig. 6, the shell air inlet 11 is formed on the first side 141, the shell air outlet 12 is formed on the third side 143, the auxiliary air inlet 13a is formed on the second side 142, and the auxiliary air inlet 13b is formed on the fourth side 144.

As shown in fig. 7, the shell air inlet 11 is formed on the first side 141, the shell air outlet 12 is formed on the third side 143, and the auxiliary air inlet 13a is formed on the second side 142.

As shown in fig. 8, the shell air inlet 11 and the shell air outlet 12 are formed on the first side 141, the auxiliary air inlet 13a is formed on the second side 142, and the auxiliary air inlet 13b is formed on the fourth side 144.

In the structures shown in fig. 6 to 8, since the shell air inlet 11 and the auxiliary air inlet 13 are located on different sides of the shell 14, heat dissipation air can be introduced into the shell 14 from different sides of the shell 14, and the air inlet of each air inlet is not affected by mutual interference, so that the air inlet has enough air inlet quantity.

From the foregoing, it is apparent that, for the depilatory and/or skin rejuvenation device, the heat generating components within the skin treater mainly include the light emitting assembly and the cold compress assembly. As shown in fig. 1 to 3, the light emitting assembly includes a light source 5 and a reflective cup 51 mounted in a housing assembly, and the light source 5 may be a pulse lamp, a laser, or an LED lamp. For emitting target light to human skin.

The target Light emitted from the pulse lamp may include at least one of IPL Light, OPT (Optimal Pulsed Light, perfect pulse Light) and DPL (Dye Pulsed Light). The target light emitted by the laser is mainly laser. The target light emitted by the LED lamp is mainly LED 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 5 of the above-described various target lights, or may be provided with two or more light sources 5 of the above-described various target lights at the same time. And are not limited thereto.

The cold compress assembly mainly comprises a refrigerating member 6 and a cold compress member 7. The refrigerating element 6 may be a semiconductor refrigerating plate (also called thermoelectric refrigerating plate) which includes a cold surface and a hot surface. The refrigerating element 6 can generate a low temperature on the cold side after the energization. The cold face is in contact with the cold compress 7, thereby continuously cooling the cold compress 7. The light-emitting surface of the cold compress 7 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 temperature rise of hair follicles can be relieved or even eliminated.

In order to facilitate the heat dissipation of the heat generated by the cooling element 6, a heat dissipation assembly 8 may be connected to the hot side of the cooling element 6 as shown in fig. 1 to 3. At this time, the heat dissipation duct 2 may be configured to conduct the heat dissipation wind to the light emitting assembly and the heat dissipation assembly 8, respectively, to dissipate the heat of the light emitting assembly and the heat dissipation assembly 8, respectively. Therefore, the main heating component in the skin treater can be radiated, so that the temperature of the skin treater can be effectively reduced.

The heat dissipation component 8 may include heat dissipation fins, and the heat dissipation fins may be directly connected to the hot surface of the refrigeration unit 6. In addition, the heat dissipation assembly 8 may further include a heat conduction member and heat dissipation fins, and the heat dissipation fins may be connected to the hot surface of the refrigeration member 6 through the heat conduction member. Specifically, the heat conductive member may employ a heat pipe or a temperature equalizing plate.

The cold compress 7 may be made of a crystalline or amorphous material. For example, when the material of the cold pack 7 is crystal, the material of the cold pack 7 may be sapphire, ruby, emerald, quartz, crystal, or the like. When the material of the cold pack 7 is amorphous, quartz glass may be used as the material of the cold pack 7. The materials have better heat resistance and thermal conductivity.

Specifically, in one possible implementation, as shown in fig. 4, the heat dissipation duct 2 may include a main duct 23, a first branch duct 24, and a second branch duct 25. Wherein, one end of the first air-dividing duct 24 is communicated with the main duct 23, and the other end is communicated with the shell air outlet 12. One end of the second air-dividing duct 25 is communicated with the main air duct 23, and the other end is communicated with the shell air outlet 12. At this time, the air inlet 21 of the air duct is the air inlet of the main air duct 23, and the air outlets of the air duct are the air outlets of the first air-dividing duct 24 and the second air-dividing duct 25 respectively. Wherein, the light emitting component is disposed in the first air distribution duct 24, and the heat dissipating component 8 is disposed in the second air distribution duct 25.

In another possible implementation manner, as shown in fig. 5, the heat dissipation air duct 2 includes a first air-dividing duct 24a and a second air-dividing duct 25a, the air inlet of the first air-dividing duct 24a and the air inlet of the second air-dividing duct 25a are both formed at the air inlet of the air duct, the air outlet of the first air-dividing duct 24a and the air outlet of the second air-dividing duct 25a are respectively communicated with the shell air outlet 12, the light-emitting component is disposed in the first air-dividing duct 24a, and the heat dissipation component 8 is disposed in the second air-dividing duct 25 a. In this embodiment, the first fan outlet 31 is located outside the heat dissipation air duct 2, and the first fan outlet 31 is spaced from the air duct air inlet 21, so that the auxiliary air inlet gap 4 is formed between the periphery of the air duct air inlet 21 and the periphery of the first fan outlet 31.

The number of the case outlets 12 may be one or two or more. For example, as shown in fig. 5, the shell air outlet 12 is one, and at this time, the air outlet of the first air-dividing duct 24a and the air outlet of the second air-dividing duct 25a are both communicated with the same shell air outlet 12. For another example, as shown in fig. 4, the number of the shell air outlets 12 is two, and at this time, the air outlet of the first air-dividing duct 24 is correspondingly communicated with one of the shell air outlets 12a, and the air outlet of the second air-dividing duct 25 is correspondingly communicated with the other shell air outlet 12b.

Therefore, the radiating air duct 2 can be divided into two paths, so that the light emitting component and the radiating component 8 are respectively subjected to radiating and cooling.

The heat generating component may be other components in the skin treatment device, such as a capacitor, in addition to the light emitting unit and the cooling unit 6. Therefore, the number of the air dividing channels of the heat dissipation air channel 2 can be correspondingly designed according to the actual heat dissipation requirement, which is not limited herein.

In addition, when the heat dissipation air duct 2 is specifically manufactured, an air duct bracket can be arranged in the shell component 1 to enclose the heat dissipation air duct 2, and the air duct bracket can be manufactured separately from the shell component 1 or can be manufactured integrally with the shell component 1.

In a second aspect, another skin treater provided by embodiments of the present application may also utilize bernoulli's principle at the housing air outlet 12 to increase the heat dissipation efficiency.

As shown in fig. 9 to 12, the skin treater includes a housing assembly 1, and a housing air inlet 11 and a housing air outlet 12 are provided on the housing assembly 1. The second fan 9 is arranged at a position close to the shell air outlet 12, the second fan 9 is used for sending out heat dissipation air to the outside of the shell air outlet 12, the second fan 9 comprises a second fan outlet 91 corresponding to the shell air outlet 12, and the air outlet area of the second fan outlet 91 is smaller than or equal to the air outlet area of the shell air outlet 12.

In order to achieve the effect of increasing the air output by using the bernoulli principle, as shown in fig. 10, an auxiliary air outlet gap 10 is formed between the periphery of the casing air outlet 12 and the periphery of the second fan outlet 91. The auxiliary air outlet gap 10 is configured to allow air near the air outlet 12 of the inner casing of the casing assembly 1 to be sucked out of the casing assembly 1 through the auxiliary air outlet gap 10 when the heat radiation air blown out from the second fan outlet 91 is sent out of the casing assembly 1 through the casing air outlet 12.

In the skin treater provided in the second aspect of the present application, since the air outlet area of the second fan outlet 91 is smaller than or equal to the air outlet area of the shell air outlet 12, an auxiliary air outlet gap 10 is formed between the periphery of the shell air outlet 12 and the periphery of the second fan outlet 91. According to Bernoulli principle, after the second fan 9 is started, the air flow rate at the air outlet side of the second fan 9 is increased, the pressure is reduced, so that the hot air around the auxiliary air outlet gap 10 in the shell assembly 1 flows and gathers to the auxiliary air outlet gap 10 and flows out from the shell air outlet 12, and a large amount of hot air can be brought out of the shell assembly 1 by the second fan 9. Therefore, the second fan 9 with smaller power can suck more hot air out of the shell assembly 1, so that the heat dissipation efficiency inside the skin processor is improved on the premise of saving energy.

The auxiliary air outlet gap 10 is implemented in various ways, and the following examples are respectively illustrated:

for example, as shown in fig. 9 and 10, the second fan outlet 91 is located inside the shell air outlet 12, and the second fan outlet 91 is spaced from the shell air outlet 12. At this time, the space between the second fan outlet 91 and the shell air outlet 12 is the auxiliary air outlet gap 10.

As another example, as shown in fig. 11 and 12, the air outlet area of the second fan outlet 91 is smaller than the air outlet area of the shell air outlet 12, and the second fan outlet 91 may be extended into the shell air outlet 12. Thereby, an auxiliary air outlet gap 10 is formed between the inner wall of the air duct outlet and the outer wall of the second fan outlet 91.

The effect of increasing the air output can be realized through the Bernoulli effect in the two modes.

Specifically, the first fan 3 and the second fan 9 may be the same fan, or may be different types of fans. For example, when the first fan 3 employs a vortex fan, the second fan 9 may employ an axial flow fan or a vortex fan.

It should be noted that, in a specific application, only one embodiment of the first aspect and the second aspect may be adopted, as shown in fig. 1 or fig. 9, that is, only the first fan 3 or only the second fan 9 is provided. It is also possible to use both embodiments of the first and second aspects in the same skin treater, as shown in fig. 11, i.e. to provide both the first fan 3 and the second fan 9, and to increase both the intake and the output.
