[0003] Most of the depilation instruments and cosmetic instruments on the market use IPL light sources for depilation, whitening, skin tendering and other cosmetic and skin care; the greater the energy, the more significant the treatment effect, but the greater the energy, the more burning and pain it will cause; the greater the energy, the slower the speed of the flash, and the shorter the service life of the lamp tube. Due to the characteristics of IPL light source, which is strong pulse light, short light-emitting time and high peak energy, the continuity of the light spectrum is not good; for different skin colors and treatment needs (such as different needs of removing spots, whitening, tendering skin, and removing wrinkles), the lamp tube light source utilization rate is greatly reduced when precise band treatment is required (for example, DPL); in addition, the characteristics of IPL light source determine that the near-infrared spectrum above 1200nm is also relatively low, which is not good for cosmetic effect.

[0054] In this embodiment, the transparent crystal 12 installed in the light outlet window at the front end of the therapeutic instrument forms a light outlet, and the transparent crystal 12 is cooled by the semiconductor refrigeration element 80. The transparent crystal 12 and the semiconductor refrigeration element 80 are shaped to match each other, and the semiconductor refrigeration element 80 cools the periphery of the transparent crystal 12, i.e., the periphery of the light outlet. The transparent crystal 12 is a full-surface transparent crystal and can be in contact with the skin.

[0055] The semiconductor refrigeration element 80, also known as a thermoelectric cooler (TEC), a heat pump, or a Peltier cooler, includes a semiconductor particle layer 82 in the middle and hot and cold faces 83 and 81 at both ends. It also includes a pair of positive and negative electrodes to electrically connect the circuit of the semiconductor refrigeration element to a control module provided on the main control panel 40 or a separately provided control panel. The independent control panel is electrically connected to the main control panel 40. The two ends of the semiconductor particle layer are the cold end and the hot end.

The cold end circuit is electrically connected to the cold end of the semiconductor particle layer, and the hot end circuit is electrically connected to the hot end of the semiconductor particle layer to form the internal circuit of the semiconductor refrigeration element. After being powered on, a temperature difference is formed between the cold face 81 and the hot face 83.

[0056] In some embodiments, when the transparent crystal 12 serves as the cold face 81 of the semiconductor refrigeration element, a group or multiple groups of cold end circuits are provided on the transparent crystal. The group or multiple groups of cold end circuits are welded and electrically connected to the cold end of a group or multiple groups of semiconductor particle layers 82.

The cold end circuit is electrically connected to the cold end of the semiconductor particle layer, and the hot end circuit is electrically connected to the hot end of the semiconductor particle layer to form the internal circuit of the semiconductor refrigeration element 80. After being powered on, a temperature difference is formed between the transparent crystal cold face 12 / 81 and the hot face 83. The transparent crystal cold face 12 / 81 is at a low temperature for refrigeration, and the hot face 83 is at a high temperature, which needs to be cooled.

[0058] In other alternative manners, referring to Fig. 5 , the cold surface 81 of the semiconductor refrigeration device 80 is a whole transparent crystal; at this time, the transparent crystal cold surface 81 and the transparent crystal 12 are used together, and there is no need to separately arrange the transparent crystal 12.

The transparent crystal cold surface can be in contact with the skin. The semiconductor particle layer 82 and the hot surface 83 can be arranged in a ring shape and welded to the edge ring of the transparent crystal cold surface 81.

[0059] The main shell 10 also has a heat sink 70 for dissipating heat from the semiconductor refrigeration device 80. The heat sink 70 includes heat dissipation fins 71 and a heat-conducting member 72, one end of which is quickly and heat-conductively connected to the heat dissipation fins 71, and the other end is quickly and heat-conductively connected to the hot surface 83 of the semiconductor refrigeration device 80, so as to quickly transfer the heat of the hot surface to the heat dissipation fins 71 for heat dissipation. The shape of the heat-conducting member at both ends is designed according to the principle of quick heat transfer. For example, the front end is arranged in a ring shape, which is in contact with the ring-shaped hot surface 83 to maximize the heat transfer area, and the rear end is a straight rod inserted into a group of parallel heat dissipation fins 71 to contact and transfer heat to the heat dissipation fins 71. In other embodiments, the front end can also be bent, and the heat-conducting member as a whole can be L-shaped; it can also be of other shapes. The heat-conducting member 72 is a heat transfer structure, which can be made of a single heat-conducting material, e.g., aluminum / copper / graphene, or a heat pipe / VC / ultra-heat-conducting pipe or plate, e.g., ALVC (aluminum ultra-heat-conducting pipe or plate), which uses phase change (evaporation and condensation). The heat dissipation fins 71 are preferably located behind the ventilation holes on the main shell to facilitate air cooling.

When the radio frequency / EMS control panel is independently provided, the radio frequency / EMS control panel is electrically connected to the main control panel 40, and the power module of the radio frequency / EMS control panel is powered by the power module on the main control panel 40. In other embodiments, the radio frequency / EMS control panel can also be integrated on the main control panel 40, and the control module, the power module, the radio frequency / EMS driving module, and the like are integrated on the main control panel 40. The radio frequency / EMS electrode 90 can be strip-shaped or columnar or arc-shaped or ring-shaped or any other suitable shape, and the radio frequency / EMS electrode 90 can be arranged to overlap the light outlet or arranged on the periphery of the light outlet, and more than one pair of radio frequency / EMS electrodes are provided. The rear end of each pair of radio frequency / EMS electrodes forms a radio frequency / EMS positive and negative electrode, which is electrically connected to the radio frequency / EMS control panel or the main control panel. The radio frequency / EMS control panel or the main control panel 40 provides the radio frequency / EMS driving module with the voltage required by the corresponding gear through the power module, the radio frequency / EMS driving module converts the DC power voltage into a high-voltage sine wave through a step-up transformer to output to the control module, and the control module outputs the radio frequency / EMS current to the skin of the user through the radio frequency / EMS electrode 90 to perform radio frequency / EMS treatment or radio frequency / EMS beauty on the skin.

[0073] In the embodiment, the light exit window of the front end of the therapeutic apparatus body is formed by the transparent crystal 12, and the transparent crystal 12 is refrigerated by the semiconductor refrigeration device 80. The transparent crystal 12 and the semiconductor refrigeration device 80 are matched in shape, and the semiconductor refrigeration device 80 refrigerates the periphery of the transparent crystal 12, that is, the periphery of the light exit port. The transparent crystal 12 is a full-surface transparent crystal, and can be in contact with the skin. For example, the semiconductor refrigeration device 80 is in the shape of a ring, the hot surface 83 and the cold surface 81 are matched in shape, and the semiconductor particle layer 82 is arranged in the shape of a ring. The through hole in the middle of the ring is used for the light waves generated by the light source, that is, the halogen lamp 20 and the IPL lamp 20' to pass through. The ring-shaped semiconductor refrigeration device 80 is arranged on the rear surface (back surface) of the transparent crystal 12, and the ring-shaped cold surface 82 is attached to the edge of the transparent crystal 12 to refrigerate the periphery of the transparent crystal, so that the full-surface transparent crystal 12 is refrigerated. The transparent crystal 12 is clamped and installed by the front shell 11, and the semiconductor refrigeration device 80 is also installed in the front shell 11. In other alternative manners, refer to the description of the first embodiment.Fig. 5 The cold surface 81 of the semiconductor refrigeration device 80 is a transparent crystal cold surface formed by a whole transparent crystal. At this time, the transparent crystal cold surface 81 and the transparent crystal 12 are combined, and the transparent crystal 12 does not need to be separately arranged. The transparent crystal cold surface 81 / 12 is covered on the light-emitting window of the front shell to form a light-emitting port, and the semiconductor refrigeration device 80 is clamped and installed by the front shell 11. The transparent crystal cold surface can be in contact with the skin. The hot surface 83 and the semiconductor particle layer 82 can be arranged in a ring shape and welded with the edge ring of the transparent crystal cold surface 81.

[0074] The main shell 10 also has a heat sink 70 arranged therein for dissipating heat of the semiconductor refrigeration device 80. The heat sink 70 includes heat dissipation fins 71 and a heat conduction member 72. One end of the heat conduction member 72 is quickly and heat-transferringly connected to the heat dissipation fins 71, and the other end is quickly and heat-transferringly connected to the hot surface 83 of the semiconductor refrigeration device 80, so as to quickly transfer heat of the hot surface to the heat dissipation fins 71 for heat dissipation. The shapes of the two ends of the heat conduction member are designed according to the principle of quick heat transfer. For example, the front end is arranged in a ring shape and is in contact with the ring-shaped hot surface 83 to maximize the heat transfer area, and the rear end is a straight rod inserted into a group of parallel heat dissipation fins 71 and in contact with the heat dissipation fins 71 for heat transfer. The heat conduction member 72 is a heat transfer structure, which can be made of aluminum / copper / graphene single heat conduction material, or can be a heat pipe / VC / ultra-heat-conduction pipe or plate such as ALVC (aluminum ultra-heat-conduction pipe or plate) using phase change (evaporation and condensation). The heat dissipation fins 71 are preferably located behind the ventilation hole 101 of the therapeutic instrument shell, so as to be air-cooled. The fan 60 can be arranged on one side of the heat dissipation fins 71.

[0075] The therapeutic instrument 1000 of the embodiment is also provided with a radio frequency / EMS assembly, which includes a plurality of pairs of radio frequency / EMS electrodes 90. For example, the radio frequency / EMS electrodes are a group of columnar electrodes, and a plurality of through holes are arranged on the periphery of the transparent crystal 12 and / or the semiconductor refrigeration device 80. The radio frequency / EMS electrodes 90 are arranged in the through holes, the front ends of the radio frequency / EMS electrodes 90 are exposed outside the transparent crystal 81 / 12 to be in contact with the skin, and the rear ends are electrically connected to the main control panel 40 or an independently arranged radio frequency / EMS control panel.

[0076] In use, the device is powered on by the button group 42, the light source is activated, and the light generated by the halogen lamp 20 and / or the IPL lamp 20' is filtered by the filter 50 to obtain a predetermined wave band, and then projected to the light outlet through the light outlet channel 160 to act on the skin for photonic beauty treatment. The radio frequency / EMS function is activated by the button group 42, and the radio frequency / EMS current is generated by the electrode points formed on the surface of the transparent crystal 12 / 82 by the radio frequency / EMS electrode 90 to act on the skin for radio frequency / EMS treatment. The radio frequency / EMS function can be activated simultaneously with the photonic beauty treatment and therapy function or selectively activated. The heat sink 70 cools the semiconductor refrigeration unit 80, and the cold surface of the semiconductor refrigeration unit 80 cools the transparent crystal, which is in contact with the skin; or the cold surface of the transparent crystal of the semiconductor refrigeration unit 80 is in contact with the skin. The fan 60 draws in cold air through the air vents on the main housing to cool the heat sink 71 and the light source part.

[0077] Referring to Fig. 13 The treatment device 100 uses an electrically driven method to switch the filter 50. For example, a motor 52 and a screw assembly are installed on the lamp holder support. The screw assembly includes a screw 53 and a nut connecting piece 54. The output shaft of the motor is connected to the screw 53 and rotates synchronously. The screw 53 is inserted into the threaded hole of the nut connecting piece 54 and threadedly connected to each other. One end of the nut connecting piece 54 is fixed by the filter holder 51. The multiple filters 50 are connected to each other, which can be a soft connection. In the figure, filter A and filter B are connected in an up-down direction. The filter holder 51 clamps and fixes one of the filters 50. The screw is fixedly connected to the filter holder 51 through a connecting rod. The motor 52 drives the screw 53 to rotate forward and reverse, which makes the nut connecting piece 54 move linearly along the screw 53 (up and down in the direction shown in the figure) to synchronously drive the multiple filters to move linearly (up and down in the direction shown in the figure), thereby driving the filter holder 51 and the multiple filters 50 to move linearly (up and down) to switch (up and down) different filters to the position of the light outlet (the outlet of the reflector cup). The light wave emitted by the halogen lamp 20 and / or the IPL lamp 20' is filtered by the filter 50 and then projected to the light outlet to act on the skin outside the transparent crystal. The motor 52 is electrically connected to the main control board 40.

[0078] In other embodiments, the motor screw assembly can be replaced by an electromagnet, which drives the filter holder 51 and the multiple filters 50 to move up and down by the extension and retraction of the output shaft of the electromagnet. The electromagnet is electrically connected to the main control board 40.

[0079] The treatment instrument 1000 of the first to fourth embodiments can switch the different filters 50 to the outlet of the light outlet channel or the reflective cup in the manner of the above-described embodiments to achieve switching of the filters 50 of different wave bands. For example, a plug socket 16 is arranged on the main housing 10, and the filters 50 are inserted into the outlet position of the light outlet channel or the reflective cup from the plug socket 16, or the filters are pulled out from the plug socket 16 to switch in other filters. Alternatively, an electric drive is installed on the lamp holder support to drive the multiple filters installed on the filter support 51 to move to the outlet position of the light outlet channel or the reflective cup. The electric drive is electrically connected with the main control panel 40.

[0080] The treatment instrument 1000 of each of the above-described embodiments adopts a double light source, in which the halogen light source can obtain infrared heating. The halogen light source is also called halogen tungsten light or near-infrared light, which has good spectral continuity, a wide spectrum (up to 300-2500 nm), and more near-infrared spectrum. The IPL light source in the double light source is a strong pulsed light, which has a short light-emitting time, a high peak light energy, a fast photochemical reaction of the skin target receiving light energy, and can instantaneously increase the temperature of the skin target. However, the spectral continuity is poor, and the near-infrared spectrum is less. The advantages of the combination of the two light sources are: 1) Spectral complementation: the spectral wave band value in the same interval is increased, and the spectral values are complemented by each other; 2) Advantage complementation: in the same wave band interval, the smooth wave band of the halogen light source is used to preheat the skin target and increase the basic temperature of the skin target to reduce the loss of IPL light energy, and the instant light energy of the IPL strong pulsed light is used on the skin target after being heated. This way can reduce the energy of the IPL light source, improve the light-emitting speed of the IPL light source, and reduce the impact of the high-energy IPL lamp tube under the same treatment effect, so as to achieve the purpose of faster, gentler, safer, and more effective treatment; 3) Strengthening of cosmetic and other skin disease treatment range: the near-infrared spectrum 900-2500 nm wave band of the halogen light source resonates with the water molecules in the skin (it has been confirmed in various medical journals / papers / magazines / clinical reports that the near-infrared wave band interacts with water molecules) to heat the underlying skin, and at the same time, the skin is cooled on the outside and heated on the inside by means of refrigeration and temperature control, and then the instant photochemical heat energy impact of the IPL light source is supplemented to achieve a more comfortable body feeling and better treatment effect.

[0081] The IPL lamp 20' is excited by a capacitor battery to generate IPL photons. It can be understood that the treatment instrument 1000 of the present application can select to start both light sources at the same time, or can select to use one of the light sources.

[0082] Reference Fig. 14The RF / EMS electrode 90 of the therapeutic apparatus 1000 of each of the above embodiments can adopt the form of an accessory head mounted at the front end of the therapeutic apparatus 1000. The RF / EMS electrode accessory head comprises a shell 91, and the shell 91 is provided with through holes or mounting slots. A plurality of RF / EMS electrodes 90 are mounted in the through holes or mounting slots, the front ends of the RF / EMS electrodes 90 are exposed to the front end face of the accessory head shell to contact the skin, and the rear ends are electrically connected to the RF / EMS circuit board or the main control board 40 inside the therapeutic apparatus 1000 through an interface or a wire. The accessory head is connected to the front shell 11 of the therapeutic apparatus 1000 in a plug-in or buckling manner. The front end face of the shell of the accessory head can be transparent or opaque. When the accessory head is transparent, the accessory head can realize photonic beauty and RF / EMS treatment at the same time when connected to the therapeutic apparatus 1000. When the accessory head is opaque, only RF / EMS treatment can be started. A plurality of accessory heads can be configured for the therapeutic apparatus 1000 to replace and use.

[0083] With reference to Fig. 15Figure 1 is a schematic diagram of the cooling system of the therapeutic instrument of the present application. The cooling system involves a fan 60 and a cooling air duct. The fan 60 is used to cool the heat sink 70 of the semiconductor refrigeration device 80 and the light source part simultaneously. The arrow in the figure represents the direction of the air flow in the cooling air duct. The arrow of the light outlet on the front end of the therapeutic instrument represents the direction of the light wave irradiation. The fan 60 can generate air flow on both the upper and lower sides of the fan (axial direction), one side of which flows through the light source part, and the other side of which flows through the cooling fins 71 of the heat sink 70. The air inlet of the light source part is provided on the front end of the housing of the therapeutic instrument, which is in air flow communication with the air duct of the light source part, the air duct of the fan, and other air inlets 101 provided on the housing of the therapeutic instrument, such as the air inlets on the rear end or the side of the housing (as air outlets), to form a first cooling air duct for cooling the light source part. The first cooling air duct can be in air flow communication with the space inside the reflector cup 21, and the two ends of the reflector cup can form air inlets and air outlets. Alternatively, the first cooling air duct can be in air flow communication with the space on the outer wall surface of the reflector cup 21. Alternatively, the outer wall (or back surface) of the reflector cup can be provided with a light source part heat sink or heat dissipation device (the heat dissipation device can be the heat conduction device described in the above embodiment), which can quickly transfer heat between the reflector cup and the light source part heat sink (such as cooling fins) or heat dissipation device, and the first cooling air duct is in air flow communication with the light source part heat sink (such as cooling fins) or heat dissipation device. The upper and lower sides of the fan in the axial direction form air inlets, and the side vertical housing (outside the rotating blades) is provided with air inlets, wherein the air inlet on the upper side of the fan is in air flow communication with the air duct of the light source part as an air inlet, and the air inlets on the side vertical housing are in air flow communication with the air outlets on the rear end of the housing of the therapeutic instrument as air outlets.
