Wherein, be equipped with the installation cavity 12a and set up the light outlet 13a that communicates installation cavity 12a at casing 10 to can all be connected halogen light source 40, reflection of light subassembly 70, power spare and circuit board 80 in casing 10 and holding in installation cavity 12a, and nursing subassembly 20 and radiator unit 30 then can select to install the installation cavity 12a at casing 10 completely or partly install in the outer wall surface of casing 10 according to the volume of the installation cavity 12a of casing 10, so protect each part of skin care equipment 1 through casing 10, prolong the life of skin care equipment 1. The outer contour of the housing 10 is generally rectangular block-shaped or prismatic so as to be convenient for a user to hold. The housing 10 may be a plastic material, for example, suitable exemplary materials that may be used include, but are not limited to, hard plastics such as polyethylene, polypropylene (PP), polyamide, polyester, cellulosic, SAN, acrylic, ABS, and other thermoplastics. Thereby making the overall mass lighter for the user to grasp. Of course, the housing 10 may also be made of metal, such as aluminum alloy, which is not limited by the present application.

The care component 20 is disposed opposite to the light outlet 13a of the housing 10, and the light outlet 13a may have a rectangular or circular opening shape, so as to facilitate processing and manufacturing. The care assembly 20 can be completely accommodated in the mounting cavity 12a of the housing 10 to improve the protection of the care assembly 20, or the care assembly 20 can be partially positioned outside the housing 10, so that the care assembly 20 protruding outside the housing 10 can be closer to the skin of a human body when in use, and the touch feeling is improved.

In some structural forms, referring to fig. 3 to 5, the housing 10 includes a casing 11 and a fixing frame 12, the casing 11 encloses a mounting cavity 12a and is provided with a light outlet 13a, a light outlet channel 12a is provided in the fixing frame 12, and the fixing frame 12 is connected to an inner wall of the casing 11 and communicates the light outlet channel 12a with the light outlet 13 a. The nursing assembly 20 includes a nursing head 21, and the nursing head 21 is connected to the fixed frame 12 and is located in the light emitting channel 12 a.

The housing 11 may be formed by splicing two symmetrical half-shells 11A to enclose and form the installation cavity 12a and the light outlet 13a, so that the heat dissipation component 30, the power supply component, the halogen light source 40, the fixing bracket 71 and other components are pre-installed in one half-shell 11A, and then are covered and connected with the other half-shell 11A to enclose and form the installation cavity 12a, thereby improving the installation efficiency and facilitating the later maintenance and replacement. The fixing frame 12 may be detachably fixed to the inner wall of the housing 11 by screw connection or clamping, so as to ensure the stability of the position of the fixing frame 12. The fixing support 71 is provided with the light-emitting channel 12a, so that the positioning and mounting of the nursing head 21 are facilitated, the alignment difficulty of the nursing head 21 and the light-emitting opening 13a is reduced, and the assembly efficiency is improved. The material of the nursing head 21 can be crystalline or amorphous. For example, when the material of the nursing head 21 is crystal, the material of the nursing head 21 may be sapphire, ruby, emerald, quartz, crystal, or the like. When the material of the nursing head 21 is amorphous, the material of the nursing head 21 can be quartz glass, and the materials have better heat resistance and heat conductivity so as to improve the nursing effect on the skin.

Further, the surface of the nursing head 21 facing away from the halogen light source 40 is flush with the outer surface of the housing 11 where the light outlet 13a is provided. So in order to avoid nursing subassembly 20 protrusion shell 11's surface, not only make skin care device 1 overall appearance comparatively pleasing to the eye, and make nursing subassembly 20 be difficult to receive the collision damage.

Optionally, the care assembly 20 further includes a cooling plate 22, the cooling plate 22 is abutted against a side wall 113 of the care head 21, the cooling plate 22 is electrically connected with the power supply member, and the cooling plate 22 is used for thermally contacting with the care head 21. The cooling plate 22 may be square and have a thin plate structure. In some configurations, the cooling plate 22 may be a TEC (Thermo Electric Cooler, thermoelectric cooling plate), although in other configurations, the cooling plate 22 may be replaced with a liquid-cooled heat sink, as the application is not limited in this respect. In the actual working process, under the driving control of the circuit board 80, a cold end is formed through the refrigerating sheet 22, and cold energy is transferred to the nursing head 21 through the cold end, so that the temperature of the nursing head 21 is reduced, or the temperature of the nursing head 21 in the working process can be reduced through conducting heat of the nursing head 21 to the refrigerating sheet 22, and the function of cold compress on skin when the nursing head 21 contacts the skin is realized. Thus, under the cold compress effect of the nursing head 21, the problem that the skin temperature is too high under the continuous effect of light on the skin can be avoided, and the use experience of a user is provided.

In some constructions, the housing 11 includes a top wall 111, a bottom wall 112, and a side wall 113, the top wall 111 being disposed opposite the bottom wall 112, the side wall 113 being connected between the top wall 111 and the bottom wall 112. The side wall 113 includes a holding portion 1131 and a light emitting portion 1132, where the holding portion 1131 is used for holding by a user, and the light emitting portion 1132 is provided with a light emitting opening 13 a. Wherein, the top wall 111, the bottom wall 112 and the side wall 113 are jointly matched and enclose the mounting cavity 12a. Since the skin care device 1 is intended to be held by the user during the skin care of the skin care device 1, and the holding time is usually long, whereas the skin care device 1 itself will have a certain weight, and a certain load is imposed on the user's wrist under long holding time, the present application is characterized in that the care assembly 20 is mounted on the care section of the side wall 113, that is, in actual use, the user is in a vertically held form while holding the housing 11 of the housing 10, the tendons and ligaments of the wrist need to bear the weight of the skin care device 1, which may cause discomfort to the wrist under long holding time, compared to the form in which the care assembly 20 is mounted on the top wall 111 and the user is in a horizontally held form, and the tendons and ligaments of the wrist are less stressed, and the weight of the skin care device 1 is more dispersed on the care section of the side wall 113, so that the pressure of the skin care device 1 to the wrist under long holding time can be properly reduced, and the user can experience further care of the wrist by mounting the skin care assembly on the side wall 113 under long holding time.

The heat dissipation assembly 30 is installed in the installation cavity 12a for dissipating heat in the installation cavity 12a to the outside. In the actual use process, the halogen light source 40, the power supply component, the components on the circuit board 80 and other components generate certain heat, and if the heat is not timely dissipated to the outside, the temperature in the installation cavity 12a is too high, so that part of the components (such as the components on the circuit board 80) fail due to the too high temperature, the risk of the skin care device 1 failing is increased, and the temperature of the housing 10 is also increased, so that the housing 10 is inconvenient for a user to hold, and the use experience is affected. Based on this, the heat dissipation assembly 30 is arranged, so that the temperature in the installation cavity 12a of the skin care device 1 is reduced, the probability of damage to parts in the installation cavity 12a due to overhigh temperature is effectively reduced, and the use safety is improved.

Referring to fig. 3 to 5, optionally, an air outlet 11a communicating with the installation cavity 12a is further formed in the housing 10, the heat dissipation assembly 30 includes a fan 32, the fan 32 is installed in the installation cavity 12a, and an air outlet 321 of the fan 32 is opposite to the air outlet 11 a. The halogen light source 40 is located on a path from the air outlet 321 of the blower 32 toward the air outlet 11 a.

Wherein, through the installation cavity 12a that is formed with air exit 11a at the shell 11 of casing 10, in time distribute the heat in the installation cavity 12a to outside by air exit 11a, avoid skin care equipment 1's some parts to take place to become invalid, and can reduce the temperature of the shell 11 of casing 10, the user of being convenient for grips shell 11. The fan 32 is installed in the installation cavity 12a and is electrically connected with the circuit board 80 and the power supply piece, the air outlet 321 of the fan 32 is opposite to the air outlet 11a, and the halogen light source 40 is located on the path of the air outlet 321 of the fan 32 towards the air outlet 11a, so that under the driving of the fan 32, the air in the installation cavity 12a flows from the inside of the installation cavity 12a to the air outlet 11a, and finally flows out from the air outlet 11a to the outside so as to take away the heat in the installation cavity 12 a. In addition, an exhaust grill 90 may be connected to the housing 11 and located at the exhaust port 11a, so that the possibility of external foreign matters entering the installation cavity 12a through the exhaust port 11a can be reduced on the basis of the exhaust flow.

Further, the heat dissipation assembly 30 further includes a heat exchange member 31, and the heat exchange member 31 is abutted against one side of the bracket 71 facing away from the light reflecting member 72 and located on a path of the air outlet 321 of the fan 32 facing the air outlet 11 a. In this case, since the temperature of the light reflecting member 72 is continuously increased by continuously reflecting light when the skin care device 1 is operated, heat is transferred to the bracket 71, and thus the temperature of the housing 10 is simultaneously increased, which is not easy for a user to hold. Therefore, the heat exchange member 31 is in heat conduction contact with the support 71, and the fan 32 drives the wind in the installation cavity 12a to sequentially flow through the heat exchange member 31 and the air outlet 11a, so that heat of the support 71 of the light reflecting component 70 is dissipated to the outside of the shell 11 of the housing 10. Under the operation of the fan 32, the air in the installation cavity 12a flows out through the air outlet 11a after flowing through the heat exchange member 31, and takes away the heat exchanged on the heat exchange member 31, so as to reduce the temperature of the bracket 71, and further avoid the overhigh temperature of the housing 10. It is understood that the heat exchanging member 31 may be made of a heat conducting material, such as a metal material. In addition, when the skin care device 1 includes the cooling fin 22 abutting against the side wall 113 of the care component 20, the heat exchanging element 31 may further extend so that the cooling fin 22 abuts against for heat conduction, and further may also dissipate heat from the hot end of the cooling fin 22.

Further, the skin care device 1 may further comprise a flow guide 100. The flow guide 100 may be substantially in a cover structure, and may be made of plastic or metal, which is not limited in the present application. The flow guiding member 100 may be installed in the installation cavity 12a, and one end of the flow guiding member 100 is abutted to the heat exchanging member 31 to form a flow guiding channel in cooperation with the heat exchanging member 31, the flow guiding channel is communicated with the installation cavity 12a, and the other end of the flow guiding member 100 is abutted to the air outlet 11a, and the flow guiding channel is communicated with the air outlet 11a. Based on this, the present application sets the air guiding member 100, so that the air flowing out from the air outlet 321 of the fan 32 flows to the air outlet 11a under the guiding of the air guiding member 100, and then flows out from the air outlet 11a to the outside, thereby improving the airflow circulation efficiency and further improving the heat dissipation effect.

Further, a plurality of air flow channels 311 are formed in the heat exchanging member 31 at intervals, one end of each air flow channel 311 is communicated with the air outlet 321 of the fan 32, and the other end of the air flow channel 311 is communicated with the air outlet 11 a.

It can be understood that the heat exchange member 31 may include a substrate and a plurality of fins, where the plurality of fins are mounted on a surface of the substrate and are arranged at intervals along a width direction of the base, and the surface of each of the two adjacent fins facing each other and the surface of the substrate enclose the air outlet channel 311. Therefore, by forming the plurality of air flow channels 311, the contact area between the heat exchange member 31 and the air flow blown out from the air outlet 321 of the fan 32 is increased, so as to improve the heat dissipation efficiency.

A power element is mounted within the mounting cavity 12a and is electrically connected to the heat sink assembly 30. The power supply piece can be a storage battery such as a lithium battery with small volume and large capacity, can meet the long-time continuous and stable operation of the heat radiation component 30, the halogen light source 40 and other devices of the skin care equipment 1, and improves the working efficiency of the skin care equipment 1. And the shell 10 is provided with a charging port electrically connected with the power supply piece. So can satisfy when the electric quantity in the battery is not enough, the battery can be connected with external power source through the mouth of charging in order to charge, guarantees the electric quantity of battery, and then guarantees the stability of skin care equipment 1 work, also can avoid influencing skin care equipment 1's work because of external power source has a power failure simultaneously.

Referring to fig. 4, a circuit board 80 is installed in the installation cavity 12a, and the circuit board 80 is electrically connected with the halogen light source 40, and the circuit board 80 is provided with a booster circuit for increasing an input voltage before the halogen light source 40 is lighted.

The circuit board 80 is electrically connected to the halogen light source 40, the heat sink 30, and other components, and is used for controlling the halogen light source 40, the heat sink 30, and other components to operate. Specifically, the skin care apparatus 1 further includes a connecting member 110, and the connecting member 110 may be hook-shaped, and the circuit board 80 may have an avoidance hole formed on a board surface thereof, one end of the connecting member 110 is electrically connected to the halogen light source 40, and the other end is disposed through the avoidance hole to electrically connect to the circuit board 80, so that electrical connection between the halogen light source 40 and the circuit board 80 can be achieved. Since the halogen lamp source heats the tungsten filament 43 to generate light energy, a certain time is required for heating the tungsten filament 43, and thus, the input voltage can be increased to improve the heating efficiency of the tungsten filament 43 before the halogen lamp source 40 is lightened by arranging the booster circuit on the circuit board 80, so that the lightening time of the halogen lamp source 40 can be shortened, and the use experience of a user can be improved.

Referring to fig. 3-5, in one embodiment, a filter 60 is mounted within the mounting cavity 12a between the halogen light source 40 and the care assembly 20 for transmitting light from the halogen light source 40 in the peak wavelength range and reflecting light from the halogen light source 40 outside the peak wavelength range. The optical filter may be square or round, for example, when the light incident surface of the care component 20 is square, the optical filter may be adapted to be square, which is not limited in the present application, and the optical filter may be a sheet structure. In the direction of the halogen light source 40 to the care assembly 20, the filter is located between the halogen light source 40 and the care assembly 20. The filter 60 is configured to transmit light of the halogen light source 40 in a peak wavelength range and reflect light of the halogen light source 40 outside the peak wavelength range. In this arrangement, the filter 60 is capable of screening light rays, i.e., light rays within the peak wavelength emitted by the skin care device 1 and light rays outside the peak wavelength emitted by the skin care device 1, which are directed toward the care assembly 20, and light rays outside the peak wavelength are reflected back by the filter. Therefore, the light reaching the skin can be only light within the peak wavelength, namely only the partial light can act on the skin, the light outside the peak wavelength is prevented from acting on the skin, for example, visible light with the wavelength range of 390 to 780 nanometers can be filtered by the optical filter, so that the pigment on the skin surface layer can be prevented from being absorbed by the visible light to form a thermal effect, the skin surface layer temperature of the skin of a user is prevented from being too high, and the use experience of the user can be improved.

In addition, when the energy of the light is concentrated in the portion of the peak wavelength, that is, the portion outside the peak wavelength, the energy of the portion having higher energy is lower, so that when the portion having higher energy passes through the care component 20 and is led to the outside of the housing 10, the portion of energy is not retained in the mounting cavity 12a, resulting in the heat in the mounting cavity 12a being raised, but is filtered by the filter to retain the portion in the mounting cavity 12a, because the energy is lower, the portion having higher energy in the mounting cavity 12a is not caused to be excessively high, based on which the heat dissipation requirement can be appropriately reduced, the number of structures of the heat dissipation component 30 can be reduced, or the lower power heat dissipation component 30 can be selected, and the general volume of the lower power heat dissipation component 30 can be reduced compared with the higher power heat dissipation component 30, so that the space occupied by the heat dissipation component 30 in the skin care device 1 can be reduced, the components in the skin care device 1 can be more flexibly arranged, and the volume of the skin care device 1 can be reduced, so that the skin care device 1 is suitable for being used in a home environment.

The halogen light source 40 is installed in the installation cavity 12a and is electrically connected with the power supply, the halogen light source 40 continuously emits light in a single working period, and the light of the halogen light source 40 is emitted out of the housing 10 through the nursing assembly 20. It will be appreciated that a duty cycle refers to a complete duty cycle in which the user starts to care skin after turning on the skin care device 1 to the end of the final care of the skin, and during which the halogen light source 40 continuously emits light without interruption stopping until the end of the final care of the skin. The halogen light source 40 and the care device 20 may be disposed opposite to each other, so as to increase the luminous flux of the halogen light source 40 for emitting external light through the care device 20.

According to the skin care device 1 of the embodiment of the application, the halogen light source 40 continuously emits light in a single working period, and the light is emitted out of the shell 10 through the care component 20 to care the skin of a user, so that compared with the scheme of stroboscopic light emission of a xenon lamp in the prior art, the skin care device 1 of the application has high light energy output density, so that the user can realize the same beauty effect in a shorter time, further the user experience is improved, the use threshold of the user is reduced, the probability of the user adhering to the beauty is increased, and the user can experience the effect of the beauty instrument more easily. Compared with the xenon lamp, the halogen light source 40 has stronger light penetrability, and the light wavelength range is larger, so that the light with larger wavelength range can balance the water absorption requirements of each layer of the skin, and further improve the skin care effect. Meanwhile, the xenon lamp of the existing skin care equipment is complicated in overall structure because high-voltage ionized xenon is required to emit light and be used together with a capacitor. The application adopts the halogen light source 40 to emit light without high-voltage ionized xenon, the installation mode is simpler, the capacitor can be eliminated, the whole volume of the skin care equipment 1 can be reduced, the weight of the skin care equipment 1 is lightened, the instantaneous energy of the halogen light source 40 for emitting light is lower, and the user experience is further improved. In addition, the care assembly 20, the heat dissipation assembly 30, the power supply and the halogen light source 40 are integrated in the same shell 10 for handheld use, so that compared with the skin care device 1 in the prior art, the cooperation mode of the body and the handle is required to be arranged, the skin care device 1 is more convenient to use, the miniaturization of the skin care device 1 is realized, the operation in a household environment is facilitated, and the use experience of a user is improved.

Optionally, the skin care device 1 further includes a dodging structure (not shown), the care assembly 20 includes a care head 21, the care head 21 is connected to the housing, the light of the halogen light source 40 is emitted out of the housing 10 through the care head 21, the dodging structure is disposed between the halogen light source 40 and the care assembly 20, and the dodging structure is used for dodging the light of the halogen light source 40 emitted to the care head 21. The light homogenizing structure is configured to homogenize the light emitted from the halogen light source 40 to the nursing head, so that the light emitted from the halogen light source 40 is homogenized and then is more uniform when finally reaching the skin of the user, thereby improving the skin care effect of the nursing light.

Further, the care head 21 is configured as sapphire, and the dodging structure is attached to a surface of the sapphire facing the halogen light source 50. It can be appreciated that sapphire has good printing opacity effect, can effectively reduce the loss of light by sapphire direction in-process to sapphire has good heat conduction effect, can cool down for skin fast. The light homogenizing structure may be a microlens array directly etched on the light incident surface of the sapphire, where the microlens array is disposed on the surface of the sapphire facing the halogen light source 40 (i.e. the light incident surface of the care component 20), and includes a plurality of microlenses distributed in an array, so that the relatively concentrated light beam is divided into a plurality of sub-beams by the plurality of microlenses when passing through the microlens array, so as to achieve the light homogenizing effect on the light beam. Therefore, the falling-off between the microlens array and the sapphire can be avoided, and the assembly steps can be reduced. Of course, in other structural forms, the light homogenizing structure can also be a light homogenizing sheet, and the light homogenizing sheet is attached to the light incident surface of the sapphire so as to facilitate replacement. The application is not limited in this regard.

Referring to fig. 3, 4 and 6 in combination, in some configurations, the halogen light source 40 includes a tube 41, two conductive members 42 and a tungsten wire 43, and a halogen gas is disposed in the tube 41. The two conductive members 42 are connected to two ends of the tube 41 and extend into the tube 41. The tungsten wire 43 is disposed in the tube 41, and opposite ends of the tungsten wire 43 are respectively connected to the two conductive members 42, wherein the diameter of the tungsten wire 43 ranges from 0.1mm to 0.5mm.

When the conductive members 42 connected to two ends of the tungsten filament 43 are energized, the two conductive members 42 apply a specific voltage to two ends of the tungsten filament 43, so that the tungsten filament 43 heats and radiates near infrared light, and the near infrared light passes through the tube 41 to be emitted to the care component 20. And the tube body 41 is made of a transparent material such as quartz glass or the like. And the tube 41 can be cylindrical, so that the halogen light source 40 can uniformly emit light in the circumferential direction, and the alignment difficulty with the nursing assembly 20 is reduced during installation, and the convenience of installation is improved. It should be noted that, the two conductive members 42 may be fixed on the circuit board 80, and electrically connected to the power source member through the circuit board 80.

When the diameter of the tungsten wire 43 is less than 0.1mm, the tungsten wire 43 is weak, resulting in an increased possibility of breakage, which affects the service life of the halogen light source 40. When the diameter of the tungsten wire 43 is larger than 0.5mm, the surface area and volume of the tungsten wire 43 are small, and the luminous efficiency is relatively low. Therefore, by limiting the diameter range of the tungsten wire 43 to 0.1mm to 0.5mm, the tungsten wire 43 has a higher surface area to volume ratio, the energy conversion efficiency can be improved, the heat dissipation is enhanced, and meanwhile, the overall structural strength of the tungsten wire 43 is considered, and the tungsten wire can bear higher temperature and pressure without breaking. Specifically, the diameter of the tungsten wire 43 may be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, or the like.

Further, the tungsten wire 43 is spirally extended along the length direction of the tube body 41, and the length of the tungsten wire 43 ranges from 100mm to 1000mm. By spirally extending the tungsten wire 43 along the longitudinal direction of the tube 41, the length of the tungsten wire 43 can be extended, and the whole length of the tube 41 can be prevented from becoming too long. The different lengths of the tungsten filaments 43 have an effect on the brightness, energy consumption, heat dissipation and mechanical stability of the tungsten filaments 43. Generally, longer tungsten filaments 43 may produce a brighter light output than shorter tungsten filaments 43. This is because the longer tungsten filaments 43 provide more surface area for current to flow through and thus emit more light. Thus, if brightness is a priority, longer tungsten filaments 43 may be preferred. Longer tungsten filaments 43 generally require more energy to operate because of their larger volume and thus higher electrical resistance. This means that a shorter tungsten wire 43 can be more energy efficient because it requires less power to produce a similar brightness level. Shorter lengths of tungsten wire 43 may be more desirable if energy efficiency is a concern. The tungsten wire 43 heats up when energized, and the length of the tungsten wire 43 affects heat dissipation. Longer tungsten wires 43 typically have a larger surface area, which helps to dissipate heat and helps to prevent overheating. On the other hand, a shorter tungsten wire 43 may generate less heat due to its smaller volume. The length of the tungsten wire 43 is selected to take into account the heat dissipation requirements of the particular application. Longer tungsten filaments 43 generally have greater mechanical stability and are less prone to sagging or breakage. As they have more support points along their length. Conversely, shorter filaments may be more prone to deformation or breakage under pressure. Thus, if mechanical stability is important, a longer tungsten wire 43 may be preferred.

Thus, when the length of the tungsten wire 43 is greater than 1000mm, although the longer tungsten wire 43 provides a larger surface area for current to flow therethrough, thereby emitting more light, and has higher mechanical stability, and is less prone to sagging or breakage. Longer tungsten filaments 43 generally require more energy to operate and generate more heat. On the other hand, when the length of the tungsten wire 43 is less than 100mm, the power consumption is low, but the brightness is low and the wire is easily broken. The length of the tungsten wire 43 may thus be defined in the range of 100mm to 1000mm, for example 100mm, 300mm, 500mm, 700mm and 900mm. Therefore, the balance of brightness, energy consumption, heat dissipation and mechanical stability can be achieved.

Alternatively, the distance between opposite ends of the tungsten wire 43 in the length direction of the tube body 41 is defined as L,5 mm.ltoreq.L.ltoreq.100 mm. It will be appreciated that the distance between the opposite ends of the tungsten wire 43 in the length direction of the tube body 41 is actually the light emitting area of the halogen light source 40. When L is less than 5mm, the overall light emitting area of the halogen light source 40 is made small, resulting in a low light output, thereby affecting the nursing effect. When L is greater than 100mm, the overall light emitting area of the halogen light source 40 is large, which not only increases the power consumption, but also occupies a large volume of the housing 10, which is disadvantageous for the miniaturization of the skin care device 1. Therefore, the distance L between the opposite ends of the tungsten wire 43 in the longitudinal direction of the tube body 41 is limited to 5mm to 100mm, such as 10mm, 30mm, 50mm, 70mm, 90mm, etc., that is, the light output amount can be ensured while facilitating miniaturization of the skin care device 1.

With reference to fig. 3 and 6 in combination, further, a distance M between opposite ends of the care assembly 20 in the length direction of the tube body 41 is defined, satisfying: l=m. The above arrangement makes the light emitted from the tungsten filament 43 in the direction perpendicular to the length extension direction of the tube 41 penetrate the care assembly 20 and then be emitted, so that the light of the halogen light source 40 is reduced and directly emitted out of the light outlet 13a without passing through the care assembly 20, and the care effect of the skin care device 1 is improved.

In some constructions, the halogen light source 40 is projected toward the care assembly 20 in a stripe or ring or polygon shape. Therefore, the halogen light source can be in various shapes, such as long strips or rings, and the like, so that the halogen light source can be selected according to the installation space in the shell, and meanwhile, the halogen light source can be also adapted to nursing components in various different shapes, thereby ensuring the light output.

In some constructions, the projection of the halogen light source 40 toward the care assembly 20 falls within the care assembly 20. So that the light emitted from the halogen light source towards the nursing assembly can be emitted through the nursing assembly 20, the light of the halogen light source 40 is reduced and is directly emitted out of the light outlet 13a without passing through the nursing assembly 20, and the nursing effect of the skin care device 1 is improved.

Alternatively, the electric power of the halogen light source 40 ranges from 5W to 50W. When the electric power of the halogen light source 40 is less than 5W, the overall light output of the halogen light source 40 is low, thereby affecting the nursing effect. When the electric power of the halogen light source 40 is greater than 50W, the halogen light source 40 consumes too much power, and the pressure on the power supply member is large. Therefore, the electric power of the halogen light source 40 is limited to a range of 5W to 50W, such as 10W, 20W, 30W, etc., so that the light output amount of the halogen light source 40 can be ensured while avoiding the power consumption of the halogen light source 40 from being too high.

Referring to fig. 3, 4 and 7 in combination, in some configurations, in a direction of the halogen light source 40 toward the care assembly 20, the light reflecting assembly 70 is located on a side of the halogen light source 40 facing away from the care assembly 20, and has a reflecting surface 721 facing the halogen light source 40, the reflecting surface 721 being configured to reflect light emitted from a side of the halogen light source 40 facing away from the care assembly 20 to the care assembly 20.

In the process of actually emitting light from the halogen light source 40, the light is usually emitted in a diffuse manner, that is, the light is emitted outwards at a plurality of angles, and the halogen light source 40 is generally cylindrical in shape, that is, emits light along its own circumference, so that the incident amount of the light incident on the care assembly 20 is small, and the care effect on the skin is affected. In view of this, the present application is provided with the reflection unit, and the reflection surface 721 of the reflection unit reflects the light emitted from the side of the halogen light source 40 facing away from the care unit 20 to the care unit 20, so that the incident amount of the light finally incident to the care unit 20 can be increased, the outgoing amount of the light finally guided to the outside of the housing 10 can be increased, and the care effect on the skin can be further improved.

Further, the light reflecting member 70 includes a bracket 71 and a light reflecting member 72, the bracket 71 is coupled to the housing 10, and the light reflecting member 72 is fixed to a side of the bracket 71 facing the halogen light source 40. The reflector 72 is an annular structure having an opening disposed toward the halogen light source 40, and the surface of the reflector 72 facing the halogen light source 40 is configured as a reflective surface 721 around the side of the halogen light source 40 facing away from the care assembly 20.

The bracket 71 may be fixed to the inner wall surface of the housing 10 directly by screw connection or snap connection, or may be clamped and fixed when being covered by the two half-shells 11A of the housing 10. Reflector 72 may be a metal plate, such as aluminum, aluminum alloy, or stainless steel, so that reflector 72 itself has the ability to reflect nursing light. While reflector 72 surrounds the side of halogen light source 40 facing away from care assembly 20, and the area of reflector 72 can cover two-thirds of the area of halogen light source 40. In this way, the halogen light source 40 is surrounded by the reflector 72, so that the portion of the light emitted by the halogen light source 40, which is not directly emitted to the care assembly 20, can be reflected by the reflecting surface 721 more and is reflected to the care assembly 20 while the portion of the light emitted by the halogen light source 40, which is not directly emitted to the care assembly 20, is not blocked, so as to further improve the light utilization rate.

Still further, the cross-section of the reflecting surface 721 has a contour line arranged in a semicircular or elliptical shape or an arc or parabolic shape. It can be appreciated that the contour line of the cross section of the reflecting surface 721 is arranged in a semicircular shape, an elliptical shape, an arc shape or a parabolic shape, so that the curvature of the reflecting surface 721 can be adjusted to enable the light to be emitted by the reflecting surface 721 when the light is incident on the reflecting surface 721, and the incident amount of the light incident on the incident surface of the nursing component 20 can be further increased when the light is parallel to the incident surface of the nursing component 20 from the opening because the incident surface of the nursing component 20 is parallel to the plane where the opening is located.

In one embodiment, the light intensity peak wavelength of the light of the halogen light source 40 ranges from 900nm to 1800nm. Among them, the peak wavelength band of the light of the skin care device 1 using a xenon lamp as a light source in the conventional art is generally 1000nm or less, and the absorption coefficient of the skin water is low. Referring to fig. 8, the present application can achieve better skin care effects such as tightening skin, improving fine wrinkles, etc. by making the energy absorption effect of water of each layer in the skin of the human body better for light rays when the peak wavelength of light rays of the halogen light source 40 is between 900 and 1800nm, and by promoting metabolism of collagen cells in the skin better, stimulating collagen regeneration. In addition, the light rays with the wavelength between 900 and 1800 nanometers occupy more energy in the total wavelength of the nursing light rays, so that the nursing effect of the nursing light rays on the skin of a user can be improved, the duration of the working period of the skin nursing device can be relatively shortened under the aim of achieving the same skin nursing effect, namely the use time of the user can be properly shortened, the excessive use time of the user is not occupied, and the use experience of the user is improved; therefore, the light source structure can be a structure with smaller power, and compared with the light source structure with larger power, the light source structure with smaller power can improve the cruising ability of the skin care equipment on the basis of the power supply pieces with the same electric quantity;

Meanwhile, the energy of the light of the halogen light source 40 is lower between 400 and 450 nanometers, and the energy of the blue light is higher at the wavelength of 400 to 450 nanometers, so that the effect of reducing the energy of the blue light can be achieved, and the risk of damage of the blue light to eyes of a user is reduced; and, it also means that the energy of the nursing light is lower between 10 and 400 nanometers, and the energy of the ultraviolet rays is higher at the wavelength of 10 to 400 nanometers, so that the effect of reducing the energy of the ultraviolet rays can be achieved, and the risk of damaging the skin of a user by the ultraviolet rays is reduced.

In another embodiment, the light intensity peak wavelength range of the light of the halogen light source 40 is 1200nm to 1800nm. The absorption coefficient of water in each layer of the skin to near infrared light is better than that of near infrared light with the wavelength of 1200nm in the whole, so that when the light intensity peak wavelength of light is in the range of 1200nm to 1800nm, the energy absorption effect of water in each layer of the skin to light is better, the metabolism of collagen cells in the skin is further promoted, collagen regeneration is stimulated, and better skin care effects of tightening the skin, improving fine lines and the like are further achieved. The peak wavelength of the light may be specifically set to 1200nm or more and 1400nm or 1600nm or 1800nm or less, and the like, which is not limited by the present application.

In yet another embodiment, the light intensity peak wavelength of the light of the halogen light source 40 ranges from 1400nm to 1600nm. The absorption coefficient of water in each layer of the skin to near infrared light is in a peak value state when the wavelength range is 1400-1800 nm, so that when the peak wavelength of light is more than or equal to 1400nm and less than or equal to 1600nm, the energy absorption effect of water in each layer of the skin of a human body to the light is better, the metabolism of collagen cells in the skin is further promoted, the collagen regeneration is stimulated, the skin care effects of tightening the skin, improving fine lines and the like are further achieved, and the use experience of a user is improved. The peak wavelength of the light may be specifically set to 1400nm or more and 1500nm or less, or 1500nm or more and 1600nm or less, for example, which is not limited by the present application.

In yet another embodiment, the light intensity peak wavelength of the light of the halogen light source 40 ranges from 1300nm to 1500nm. The absorption coefficient of water in each layer of the skin to near infrared light is in a peak value state when the wavelength range is 1300-1500 nm, so that when the peak wavelength of light is more than or equal to 1300nm and less than or equal to 1500nm, the energy absorption effect of water in each layer of the skin of a human body to the light is better, the metabolism of collagen cells in the skin is further promoted, the collagen regeneration is stimulated, the skin care effects of tightening the skin, improving fine lines and the like are further achieved, and the use experience of a user is improved. The peak wavelength of the light may be specifically set to 1300nm or more and 1400nm or less, or 1400nm or more and 1500nm or less, or the like, which is not limited by the present application.

Optionally, the ratio of the sum of the energy values of the halogen light source in the light wavelength range of 900nm to 1800nm to the sum of the energy values corresponding to the total light wavelength of the halogen light source 40 is greater than 40%. The self temperature of the halogen light source 40 during operation or the form of the heat dissipation effect of the heat dissipation assembly 30 can be adjusted by adjusting the self structure of the halogen light source 40, so that the energy distribution of the light rays emitted by the halogen light source 40 can be adjusted, the energy ratio of the light rays acting on the skin with better care effect can be higher, the energy efficiency ratio of the light rays can be further improved, and the energy of the light rays of the halogen light source 40 in the wavelength range of 900-1800 nanometers is higher under the condition of the same electric quantity of the power supply in the same period of time, so that the metabolism of collagen cells in the skin is further improved, collagen regeneration is stimulated, and better skin care effects such as tightening skin, fine wrinkles and the like are further achieved.

Alternatively, the halogen light source 40 emits light having a wavelength in the range of 900nm to 1800nm with a relative intensity of greater than 40%. Referring to fig. 9, the abscissa indicates the wavelength value of light, the ordinate indicates the ratio of the light intensity of other wavelengths to the light intensity of the peak wavelength, and the light intensity of the halogen light source 40 at the peak wavelength is 1. The C curve in fig. 9 is the relative light intensity of the halogen light source 40 at different wavelength values. In the actual setting process, the self temperature of the halogen light source 40 or the heat dissipation effect of the heat dissipation component 30 can be adjusted, so that the light intensity of the halogen light source 40 at different wavelength values can be adjusted, the light intensity ratio of the light with better nursing effect, which acts on the skin, can be higher, and the penetrating power of the light can be further improved. Therefore, when the peak wavelength of the nursing light rays is in the range of 900-1800 nanometers, the duration of the working period of the skin care equipment can be relatively shortened under the aim of achieving the same skin care effect, namely, the use time of a user can be properly shortened, and the excessive use time of the user is not occupied, so that the use experience of the user is improved; in contrast, a lower power halogen light source 40 may be selected, and in general, the lower power halogen light source 40 may have a smaller volume than the higher efficiency halogen light source 40, so that the space occupied by the halogen light source 40 in the skin care device 100 may be reduced, the arrangement of the components in the skin care device 100 may be more flexible, the volume of the skin care device 100 may be reduced, so as to be suitable for use in a home environment, and the weight may be reduced appropriately, so as to be convenient for a user to hold.

The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it should be understood that, if there is an azimuth or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc., based on the azimuth or positional relationship shown in the drawings, it is only for convenience of describing the present application and simplifying the description, but it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and thus terms describing the positional relationship in the drawings are merely illustrative and should not be construed as limitations of the present patent, and specific meanings of the terms described above may be understood by those skilled in the art according to specific circumstances.
