[0053] The embodiment of the application provides a beauty instrument 10, referring to Figures 1 to 3 which comprises a shell 100, a light emitting piece 200, and a cold compress assembly 300. Under the action of the light emitting piece 200 and the cold compress assembly 300, the beauty instrument 10 can not only realize skin care for a user, but also can perform cold compress on a part of the user to be beautified, so as to obtain double effects and improve user experience.

[0054] It should be noted that the beauty instrument 10 can be held by the palm, can be held by the fingers, or can be held in other ways.

[0055] In some embodiments of the application, the beauty instrument 10 is held by the palm. The shell 100 is in the shape of a long strip as a whole. The middle part and the bottom part of the shell 100 are holding parts. The palm of a user covers the holding parts, so as to hold the beauty instrument 10.

[0056] In some embodiments of the application, referring to Figure 2 a side wall of one side of the shell 100 is provided with a light outlet 100a. The light outlet 100a can be circular, square, or in other shapes. The light outlet 100a corresponds to the light emitting piece 200, so that the light emitted by the light emitting piece 200 for beauty can pass through the light outlet 100a and be emitted to a part of the user to be beautified.

[0057] In some embodiments of the application, the shell 100 is internally provided with an accommodating space (not shown in the figure). The accommodating space can be in communication with the outside through the light outlet 100a. The accommodating space can be used to accommodate the light emitting piece 200, so as to protect the light emitting piece 200, ensure the light emitting effect of the light emitting piece 200, and further ensure the beauty effect of the beauty instrument 10.

Figure 5 A structure schematic diagram of the beauty instrument provided in the embodiments of the present application is shown. Figure 4 A structure schematic diagram of the beauty instrument provided in the embodiments of the present application is shown. Figure 6 A structure schematic diagram of the beauty instrument provided in the embodiments of the present application is shown. Figure 4 An enlarged structure schematic diagram of the cold compress assembly and the light emitting piece at A in the beauty instrument provided in the embodiments of the present application is shown. Figure 7 A cross-sectional structure schematic diagram of the fixed part and the shell fixedly connected provided in the embodiments of the present application is shown.

[0059] In some embodiments of the present application, as shown in Figures 2 to 6 The cold compress assembly 300 is arranged at the light emitting port 100a, and is arranged spaced apart from the light emitting piece 200 in the light emitting direction of the light emitting piece 200, that is, the cold compress assembly 300 is closer to the skin part to be treated, and the cold compress assembly 300 and the light emitting piece 200 are arranged in sequence in the thickness direction of the shell 100. When the light emitting piece 200 performs the treatment on the skin part to be treated, the cold compress assembly 300 performs the cold compress treatment on the skin part to be treated, so as to reduce the burning sensation caused by the beauty instrument 10 to the skin part to be treated.

[0060] In some embodiments of the present application, the cold compress assembly 300 and the shell 100 are detachably connected, that is, the cold compress assembly 300 can be installed when needed, so as to perform the cold compress on the skin of the user, and the cold compress assembly 300 can be removed when not needed, so as to reduce the shielding effect of the cold compress assembly 300 on the light emitted by the light emitting piece 200, reduce the light loss of the light emitted by the light emitting piece 200, and better perform the treatment on the skin part to be treated.

[0061] That is, the detachable connection between the cold compress assembly 300 and the shell 100 can determine whether to install the cold compress assembly 300 according to different needs, and improve the use experience of the user.

[0062] For example, when the user does not need the cold compress, for example, in low temperature weather or the user is not sensitive to the pain caused by the hair removal, or the user pays more attention to the effectiveness of the hair removal and the time required for the hair removal, the cold compress assembly 300 can be removed from the shell 100 at any time, so as not to use the cold compress function. In this way, the light emitted by the light emitting piece 200 is not shielded by the cold compress assembly 300, the light loss of the light emitted by the light emitting piece 200 is reduced, and the cold compress can also avoid the cold shrinkage effect on the hair follicle pores of the skin of the user, so as to affect the pyrolysis effect of the beauty light on the hair follicle part. When the user needs the cold compress, the cold compress assembly 300 is installed at the light emitting port 100a of the shell 100, so as to perform the cold compress on the skin of the user while performing the treatment on the skin of the user, and reduce the pain and burning sensation of the skin.

[0063] In some embodiments of the present application, as shown in Figure 2As shown in FIGS. 1 and 2, the light outlet 100a is in a circular structure, and the cold compress assembly 300 includes a fixing component 310 and a cold compress component 320. The fixing component 310 is similar in shape to the light outlet 100a, and is in the form of a ring and arranged at the light outlet 100a in a detachable manner between the fixing component 310 and the shell 100. The cold compress component 320 is arranged on the fixing component 310 and can act on the part of the user to be beautified to compress the part of the user to be beautified. In this way, the cold compress component 320 can be detachably connected to the shell 100 through the fixing component 310, so as to be mounted on the shell 100 and removed from the shell 100.

[0064] That is, the cold compress component 320 is detachably connected to the shell 100 through the fixing component 310, which not only ensures the convenience of mounting and dismounting the cold compress component 320, but also avoids the direct connection of the cold compress component 320 to the shell 100, thereby ensuring the integrity of the cold compress component 320 and the cold compress effect of the cold compress component 320.

[0065] In some embodiments of the present application, the cold compress component 320 includes a cold compress piece 321. The shape of the cold compress piece 321 can be designed according to the shape of the light outlet 100a. For example, when the light outlet 100a is circular, the cold compress piece 321 is also circular; when the light outlet 100a is square, the cold compress piece 321 is also square. In this way, the shape of the cold compress piece 321 is matched with the shape of the light outlet 100a, so as to completely cover the beauty light emitted by the light emitting piece 200 to the direction of the light outlet 100a, thereby ensuring the cold compress effect of the cold compress piece 321.

[0066] In some embodiments of the present application, as shown in FIGS. 1 and 2, the cold compress piece 321 includes a contact portion 3210 and a conduction portion 3211 arranged in layers. Figure 3 and Figure 6 As shown in FIGS. 1 and 2, the cold compress piece 321 includes a contact portion 3210 and a conduction portion 3211 arranged in layers. The contact portion 3210 is arranged on the side of the conduction portion 3211 away from the light emitting piece 200, that is, the contact portion 3210 acts on the skin surface. In addition, the contact portion 3210 is concentric with the conduction portion 3211, and the diameter of the contact portion 3210 is smaller than the diameter of the conduction portion 3211, that is, a stepped structure is formed between the contact portion 3210 and the conduction portion 3211.

[0067] It is worth mentioning that the contact portion 3210 and the conduction portion 3211 can be integrally formed or assembled.

[0068] In some embodiments of the present application, as shown in FIGS. 1 and 2, the cold compress piece 321 includes a contact portion 3210 and a conduction portion 3211 arranged in layers. Figure 7As shown, the fixing component 310 is sleeved outside the contact part 3210, and the side of the fixing component 310 close to the light emitting element 200 abuts against the side of the conducting part 3211 away from the light emitting element 200. That is, the cold compress part 321 is clamped on the fixing component 310. Since the side of the conducting part 3211 away from the light emitting element 200 abuts against the side of the fixing component 310 close to the light emitting element 200, when the fixing component 310 is fixedly connected with the shell 100, the fixing component 310 can limit the displacement of the conducting part 3211 away from the light emitting element 200, fix the cold compress part 321 on the shell 100, and ensure the cold compress effect of the cold compress part 321.

[0069] In some embodiments of the present application, referring to Figure 6 As shown, the cold compress part 320 can further include a refrigeration element 322. The refrigeration element 322 is arranged on the side of the cold compress part 321 close to the light emitting element 200. The refrigeration element 322 can reduce the temperature of the cold compress part 321, so that the cold compress part 321 can quickly cool the skin surface and reduce the heat transfer to the skin, thereby reducing the burning and stinging sensation.

[0070] The refrigeration element 322 can be annular, strip-shaped, or other shapes, as long as it can refrigerate the cold compress part 321 while avoiding blocking the light emitted by the light emitting element 200.

[0071] It should be noted that the side of the refrigeration element 322 away from the light emitting element 200 abuts against the side of the conducting part 3211 close to the light emitting element 200, and the temperature of the conducting part 3211 is reduced by the refrigeration element 322. After the temperature of the conducting part 3211 is reduced, the temperature of the contact part 3210 is reduced, so that the contact part 3210 can quickly cool the skin surface, reduce the heat transfer to the skin, and thereby reduce the burning and stinging sensation.

[0072] In some embodiments of the present application, the cold compress part 321 can adopt a device with good light transmission and good thermal conductivity, such as sapphire (Al2O3), quartz, and K9 glass. By adopting the cold compress part 321 with good light transmission and good thermal conductivity, the light emitted by the light emitting element 200 can be avoided from being blocked, the amount of light emitted can be ensured, the refrigeration element 322 can quickly cool the cold compress part 321, the skin surface can be quickly cooled, the heat transfer to the skin can be reduced, and the use experience can be improved.

[0073] In some embodiments of the present application, the refrigeration element 322 can adopt a semiconductor refrigeration sheet. The refrigeration element 322 can form a cold face and a hot face under the condition of being powered on, the cold face abuts against the conducting part 3211, the conducting part 3211 is refrigerated by the cold face, and the temperature of the cold compress part 321 is gradually reduced.

[0074] In some embodiments of the present application, the cosmetic instrument 10 further comprises a driving circuit board (not shown in the figure). The driving circuit board is connected with the refrigeration component 322, and the driving circuit board can control the refrigeration component 322 to generate the cold face and the hot face. The driving circuit board comprises a first electrode (not shown in the figure) and a second electrode (not shown in the figure), for example, the first electrode is a positive electrode, and the second electrode is a negative electrode.

[0075] In some embodiments of the present application, the refrigeration component 322 comprises a first connecting port (not shown in the figure) and a second connecting port (not shown in the figure), and the first connecting port and the second connecting port are respectively electrically connected with the first electrode and the second electrode. The first electrode transmits the current to the first connecting port, the current flows through the refrigeration component 322 and flows out from the second connecting port, and finally the current flows back to the second electrode, forming a current loop. During the current flow, the opposite two faces of the refrigeration component 322 respectively form the cold face and the hot face. The cold face of the conductive part 3211 of the cold compress component 321 corresponds to the face close to the light-emitting component 200, and is attached to the face close to the light-emitting component 200, so as to absorb the heat on the conductive part 3211, and then quickly reduce the temperature on the cold compress component 321.

[0076] For example, the refrigeration component 322 comprises a first ceramic sheet, a second ceramic sheet, a P-type semiconductor, an N-type semiconductor, a first current guide strip and a second current guide strip. The P-type semiconductor, the N-type semiconductor, the first current guide strip and the second current guide strip are arranged between the first ceramic sheet and the second ceramic sheet, the first ceramic sheet is provided with the first current guide strip, the second ceramic sheet is provided with two second current guide strips arranged at a distance from each other, one end of the P-type semiconductor and the N-type semiconductor is connected with the first current guide strip, and the other end of the P-type semiconductor and the N-type semiconductor is respectively connected with two different second current guide strips. The first connecting port is connected with one second current guide strip, and the second connecting port is connected with the other second current guide strip. When the first connecting port releases the current, the current flows through the second current guide strip, the N-type semiconductor, the first current guide strip, the P-type semiconductor and the second current guide strip in sequence, and finally flows back into the second connecting port, forming a current loop. When the current flows through the P-type semiconductor and the N-type semiconductor, the first ceramic sheet and the second ceramic sheet respectively absorb heat and release heat, so as to form the cold face and the hot face respectively.

[0077] It can be understood that the refrigeration component 322 can use multiple P-type semiconductors and N-type semiconductors to increase the cooling effect on the cold compress component 321.

[0078] It is worth mentioning that after the fixing component 310 and the shell 100 are installed, the face of the conductive part 3211 close to the light-emitting component 200 is attached to the cold face of the refrigeration component 322, so as to ensure that the refrigeration component 322 can transmit the cold to the conductive part 3211, reduce the heat of the conductive part 3211, and then ensure the cold compress effect of the cold compress component 321.

[0079] In some embodiments of the present application, referring toFigure 6 As shown, the cold compress component 320 further comprises a conducting member 323, so as to timely transfer the heat on the hot surface of the refrigeration member 322, and cool the hot surface of the refrigeration member 322, so as to ensure the refrigeration effect of the refrigeration member 322, and further ensure the cold compress effect of the cold compress component 321.

[0080] In some embodiments of the present application, referring to Figure 6 As shown, the conducting member 323 comprises a conducting plate 3230 and a conducting pipe 3231. The conducting plate 3230 and the conducting pipe 3231 can be annular, or strip-shaped, or other shapes, as long as they can transfer heat and prevent the light emitted by the light emitting component 200 from being blocked.

[0081] The conducting plate 3230 is in contact with the hot surface of the refrigeration member 322 on one side, so as to absorb the heat generated by the hot surface. The conducting plate 3230 can be made of a material with good thermal conductivity, such as copper, aluminum, etc., so as to timely transfer the heat on the refrigeration member 322.

[0082] In addition, the conducting pipe 3231 is arranged on the side of the conducting plate 3230 away from the refrigeration member 322, so as to transfer the heat on the conducting plate 3230. The conducting pipe 3231 comprises a pipe body (not shown in the figure) and a heat dissipation part (not shown in the figure), and the pipe body is arranged on the side of the conducting plate 3230 away from the refrigeration member 322, so as to take away the heat on the conducting plate 3230.

[0083] At least one heat dissipation part is arranged at the end of the pipe body, and the heat dissipation part extends towards the side away from the conducting plate 3230, so that the heat on the hot surface of the refrigeration member 322 is gradually transferred through the conducting plate 3230, the pipe body and the heat dissipation part, so as to gradually take away the temperature on the hot surface of the refrigeration member 322.

[0084] For example, the pipe body comprises two ends, and the two ends are spaced apart from each other, and one heat dissipation part is arranged at each end of the pipe body, so as to gradually take away the heat on the pipe body through the heat dissipation parts. The use of two heat dissipation parts can increase the heat transfer, improve the heat conduction efficiency of the conducting plate 3230, and further reduce the temperature of the hot surface of the refrigeration member 322.

[0085] It should be noted that the conducting pipe 3231 can also be made of a material with good thermal conductivity, such as copper, aluminum, etc., so as to quickly take away the heat on the conducting plate 3230.

[0086] In some embodiments of the present application, the beauty instrument 10 further comprises a heat sink (not shown in the figure). The heat sink is arranged in the accommodation space, and the heat sink is connected with the heat dissipation part on the conducting pipe 3231, so as to gradually take away the heat on the heat dissipation part.

[0087] It can be understood that the heat sink can adopt air cooling, water cooling or other cooling methods as long as it can cool the heat dissipation part.

[0088] For example, the heat sink adopts air cooling. As shown in Figure 6 The heat sink includes a cooling fan (not shown in the figure) and a plurality of heat dissipation fins 400 arranged in sequence. The heat dissipation part passes through all the heat dissipation fins 400 in sequence to connect with each heat dissipation fin 400, and the heat dissipation part can release heat to each heat dissipation fin 400. The cooling fan is arranged on the side of the heat dissipation fin 400 or below the heat dissipation fin 400, and the cooling fan releases cooling air between adjacent heat dissipation fins 400, which gradually takes away the heat of the heat dissipation fin 400.

[0089] That is, the heat on the hot surface of the refrigeration part 322 is gradually dissipated through the heat dissipation fins 400, the heat dissipation part, the pipe body and the heat dissipation plate 3230, thereby gradually reducing the temperature of the hot surface of the refrigeration part 322, ensuring the working effect of the cold surface of the refrigeration part 322, and further ensuring the cold compress effect of the cold compress part 321.

[0090] It can be understood that in order to facilitate the exhaust of the cooling air absorbing heat, the top of the shell 100 is also provided with a ventilation opening (not marked in the figure). After absorbing the heat on the heat dissipation fin 400, the cooling air is exhausted through the ventilation opening to avoid the cooling air remaining in the accommodation space to cause the internal temperature of the beauty instrument 10 to rise, thereby ensuring that the internal devices of the beauty instrument 10 work in a normal temperature environment.

[0091] In addition, as shown in Figure 6 In order to avoid external impurities falling into the accommodation space, the beauty instrument 10 also includes a cover plate 500. The cover plate 500 is provided with a plurality of ventilation windows, which can exhaust the cooling air after absorbing heat. The cover plate 500 can be connected with the shell 100 by screws, or can be connected with the shell 100 by buckling, or can be connected by other ways, as long as the cover plate 500 can be detachably connected with the shell 100.

[0092] In some embodiments of the present application, the fixing part 310 and the shell 100 can be connected by a detachable connection mode such as thread, magnetic attraction, buckle, screw, etc.

[0093] For example, as shown in Figure 2 , Figure 3 and Figure 6As shown, the outer wall of the annular fixing component 310 is provided with a first threaded segment 310a in the circumferential direction, and the inner wall of the light outlet 100a is provided with a second threaded segment 110. The fixing component 310 is threadedly connected with the shell 100 through the first threaded segment 310a and the second threaded segment 110. By tightening or loosening the fixing component 310, the cold compress component 320 can be fixed at or removed from the light outlet 100a, or the cold compress component 320 can be separated from the surface of the refrigeration piece 322 while being fixed at the light outlet, so that the cold compress component 320 provides a relatively mild cooling effect to the skin without the continuous cooling provided by the refrigeration piece 322. Therefore, the cold compress component 320 can be installed, removed or loosened according to different needs during use, thereby improving the user experience.

[0094] In another example, the side wall of the fixing component 310 is provided with a first magnetic attraction piece, the side wall of the shell 100 near the light outlet 100a is provided with a second magnetic attraction piece or the shell 100 is made of a magnetic material. The fixing component 310 is magnetically and detachably connected with the shell 100 through the magnetic attraction between the first magnetic attraction piece and the second magnetic attraction piece or the magnetic attraction between the first magnetic attraction piece and the shell 100.

[0095] In another example, the inner wall of the light outlet 100a is provided with a mounting groove and a clamping groove. The mounting groove is arranged to extend in the light emitting direction of the light emitting piece 200, and the clamping groove is arranged to extend in the circumferential direction of the light outlet 100a. The mounting groove and the clamping groove are in communication with each other and can be at a right angle. The side wall of the fixing component 310 is provided with a limiting protrusion. When the fixing component 310 and the shell 100 are installed, the limiting protrusion and the mounting groove on the inner wall of the light outlet 100a are aligned with each other, and then the limiting protrusion is slid into the mounting groove. When the limiting protrusion slides to the bottom of the mounting groove, the fixing component 310 is rotated clockwise or counterclockwise to slide the limiting protrusion in the fixing component 310 into the clamping groove, so as to limit the displacement of the fixing component 310 in the light emitting direction of the light emitting piece 200 and ensure the fixing effect of the fixing component 310.

[0096] It can be understood that when the fixing component 310 is removed from the shell 100, the limiting protrusion on the fixing component 310 is counterclockwise or clockwise separated from the clamping groove, so that the limiting protrusion enters the bottom of the mounting groove, and then the limiting protrusion is slid out of the mounting groove away from the light emitting piece 200, so as to remove the fixing component 310 from the shell 100.

[0097] In some embodiments of the present application, referring to Figure 6As shown, the light emitting member 200 includes a lamp 210 and a filter 220. The lamp 210 can be arranged on the side of the filter 220 away from the light outlet 100a, i.e. the lamp 210 is arranged below the filter 220. That is, the light emitted by the lamp 210 is filtered by the filter 220 and then emitted from the light outlet 100a. The filter 220 can filter the light emitted by the lamp 210 to obtain the desired corresponding beauty light.

[0098] It should be noted that the lamp 210 can be a xenon lamp 210, a high-energy light emitting LED, a halogen lamp, a tungsten lamp, a carbon filament lamp or a heat radiation lamp.

[0099] In addition, the light emitting band of the lamp 210 can be visible light such as red, green, blue and yellow, infrared light, near-infrared light, etc.

[0100] It is worth mentioning that the beauty effects of light in different bands are different, for example, the depilation band is 500-1200 nm, the milk light band is 900-1800 nm, 500-600 nm, 550-560 nm and 560-1200 nm.

[0101] In some embodiments of the present application, referring to Figure 6 As shown, the filter 220 is provided with an arc-shaped reflecting plate 600 on the side close to the lamp 210. The reflecting plate 600 and the side of the filter 220 close to the lamp 210 form a reflecting cavity. The lamp 210 is arranged in the reflecting cavity. The light emitted by the lamp 210 can be reflected to the filter 220 through the reflecting cavity, avoiding waste of light of the lamp 210, so as to improve the utilization rate of light.

[0102] In some embodiments of the present application, referring to Figure 7 As shown, the beauty instrument 10 further includes an energy storage capacitor 700. The energy storage capacitor 700 can be used to store and output electric energy.

[0103] In some embodiments of the present application, the energy storage capacitor 700 is arranged in the accommodating space of the shell 100 and is electrically connected with the light emitting member 200, so as to provide electric energy for the light emitting member 200 and control the light emitting member 200 to emit light for beauty.

[0104] It should be noted that the bottom of the shell 100 is provided with a charging port (not shown in the figure). The charging port is electrically connected with the energy storage capacitor 700. An external power supply can be connected through the charging port to charge the energy storage capacitor 700.

[0105] Figure 8 A structure schematic view of the first shell body and the second shell body connected by a connecting line is shown.

[0106] In some other embodiments of the present application, referring toFigure 8 As shown, the housing 100 includes a first housing body 120 and a second housing body 130. An energy storage capacitor 700 is housed within the receiving space of the first housing body 120. The second housing body 130 has a light outlet 100a, a light-emitting element 200, and a cooling assembly 300, all housed within the second housing body 130. The energy storage capacitor 700 is electrically connected to the light-emitting element 200 via a connecting wire 800. That is, the energy storage capacitor 700 is designed separately from the light-emitting element 200 and the cooling assembly 300. An external power supply is connected to the first housing body 120 to charge the energy storage capacitor 700 within the first housing body 120.

[0107] Figure 9 A circuit block diagram of the flash control circuit provided in an embodiment of this application is shown.

[0108] In other embodiments of this application, when the lamp tube 210 is a high-energy light-emitting LED, the flash control circuit 900 can be used to control the light-emitting LED to flash, thereby achieving a beauty effect.

[0109] Among them, see Figure 9 As shown, the flash control circuit 900 includes a light-emitting element 200, an energy storage capacitor 700, and a control circuit 900.

[0110] See Figure 9 As shown, the first terminal of the energy storage capacitor 700 is electrically connected to the first terminal of the light-emitting element 200, and the second terminal of the energy storage capacitor 700 is grounded. The first terminal of the energy storage capacitor 700 is also used to contact the power supply voltage VIN. The energy storage capacitor 700 can store a certain amount of electricity. When flashing is required, the stored electricity can be output to the light-emitting element 200, so that the light-emitting element 200 can flash accordingly.

[0111] See Figure 9 As shown, the control circuit 900 is electrically connected to the light-emitting element 200 and can control the flashing energy of the light-emitting element.

[0112] In other words, through the energy storage capacitor 700 and the control circuit 900, the light-emitting element 200 can emit flashes with different light-emitting parameters and their combinations, thereby meeting different beauty needs.

[0113] It should be noted that the flash energy of the light-emitting element 200 can be adjusted by adjusting the energy storage capacity of the energy storage capacitor 700.

[0114] It is worth mentioning that, see Figure 9As shown, the control circuit 900 includes an NMOS switch tube Q1, a freewheeling diode D2, and a choke inductor L1. The gate of the NMOS switch tube Q1 is electrically connected to the PWM control signal, and the source of the NMOS switch tube Q1 is grounded. The input end of the freewheeling diode D2 is electrically connected to the drain of the NMOS switch tube Q1, and the output end of the freewheeling diode D2 is electrically connected to the first end of the light emitting piece 200. One end of the choke inductor L1 is electrically connected to the second end of the light emitting piece 200, and the other end of the choke inductor L1 is electrically connected to the input end of the freewheeling diode D2 and the drain of the NMOS switch tube Q1. The freewheeling diode D2 and the choke inductor L1 form a freewheeling circuit to provide a sustained working current for the light emitting piece 200 when the NMOS switch tube Q1 is turned off, thereby improving the stability and service life of the light emitting piece 200. The capacitor C4 is a capacitor for filtering and stabilizing voltage.

[0115] The choke inductor L1 not only limits the current passing through the LED lamp set to prevent the LED lamp set from being damaged by overcurrent, but also stabilizes the current of the light emitting piece 200 to emit stable light when a single working PWM pulse group is used.

[0116] The NMOS switch tube Q1 serves as a switching element to control the on and off time of the light emitting piece 200 and the high-level on branch to GND (i.e., ground), thereby adjusting the current value of the light emitting piece 200 and the high-level on branch. When the NMOS switch tube Q1 is turned off, the choke inductor L1 current cannot be abruptly changed, and the current is freewheeled to the light emitting piece 200 through the freewheeling diode D2 to form a discharge circuit.

[0117] It should be noted that the high-level on branch and the low-level off branch are formed. The high-level on branch refers to the route through which the current flows when the PWM control signal is at a high level and the NMOS switch tube Q1 is turned on. The low-level off branch refers to the discharge circuit through which the current flows when the PWM control signal is at a low level and the NMOS switch tube Q1 is turned off.

[0118] In the high-level on branch, the current flows through the NMOS switch tube Q1, the freewheeling diode D2, the light emitting piece 200, and the choke inductor L1 in sequence.

[0119] In the low-level off branch, the current flows through the choke inductor L1, the capacitor C4, and the light emitting piece 200 in sequence.

[0120] Referring to Figure 9As shown, the control circuit 900 further comprises a PWM controller 910 electrically connected to the gate of the NMOS switch tube Q1, and the PWM controller 910 is configured to adjust and output a PWM control signal. The control circuit 900 further comprises a protection circuit 920 connected between the PWM controller 910 and the gate of the NMOS switch tube Q1. The protection circuit 920 comprises a first resistor R1 and a first diode D1 connected in parallel, and the input end of the first diode D1 is connected to the gate of the NMOS switch tube Q1, and the output end of the first diode D1 is connected to the PWM controller 910.

[0121] In the embodiments of the present application, by adjusting the PWM control signal, the overall current in the circuit can be adjusted, and then the size of the flash energy of the light-emitting device can be adjusted, so that the actual use requirements of different photographing and photography can be met. For example, when the duty ratio of the PWM is increased, the rising proportion of the current of the inductor L1 is increased, the overall current is large, the current effect is increased, and the flash energy is increased; when the duty ratio of the PWM is reduced, the decreasing proportion of the current of the inductor L1 is increased, the overall current is small, the current effect is reduced, and the flash energy is reduced.

[0122] Specifically, by outputting PWM-H and PWM-L of the PWM pulse wave with a specific period, limiting the pulse wave length, and adjusting the time length proportion of PWM-H and PWM-L in the period to adjust the overall average current value of the light-emitting piece 200, specifically:

[0123] When the duty ratio is increased, the time proportion of PWM-H to PWM-L is increased, the rising proportion of the current of the inductor L1 is increased, the overall current is large, the current effect is increased, and the flash energy is increased; when the duty ratio is reduced, the time proportion of PWM-H to PWM-L is reduced, the decreasing proportion of the current of the inductor L1 is increased, the overall current is small, the current effect is reduced, and the flash energy is reduced.

[0124] That is, the duty ratio of the PWM signal is adjustable, the pulse length is changed, and the beauty or hair removal energy is adjustable.

[0125] In some embodiments of the present application, referring to Figure 6 As shown, the beauty instrument 10 further comprises a lamp panel 1000 and LED lamp beads 1100. The lamp panel 1000 can adopt a ring structure, which is arranged on the side of the light filter 220 away from the lamp tube 210. The LED lamp beads 1100 are arranged in a ring array on the side of the lamp panel 1000 away from the lamp tube 210.

[0126] In an alternative embodiment, when the beauty instrument 10 performs beauty, the LED lamp beads 1100 can directly serve as a beauty lamp to perform beauty on the part of the user to be beautified, and the lamp tube 210 can be in an off state.

[0127] Another alternative embodiment, the lamp tube 210 as a cosmetic lamp, the user to the cosmetic site for cosmetic, LED lamp beads 1100 in the closed state.

[0128] Another alternative embodiment, the lamp tube 210 and LED lamp beads 1100 are opened at the same time, LED lamp beads 1100 to enhance the luminous intensity of the lamp tube 210, improve the cosmetic effect.

[0129] In some embodiments of the present application, referring to Figure 6 As shown in the figure, the cosmetic instrument 10 further comprises a support frame 1200. The support frame 1200 is annular, one end of which is covered on the lamp plate 1000, and the other end extends along the light emitting direction of the light emitting member 200. Through the support frame 1200, the lamp plate 1000 and the LED lamp beads 1100 can be located in the support frame 1200.

[0130] The support frame 1200 comprises a support body (not marked in the figure) and an annular boss (not marked in the figure) provided on the support body, the support body is arranged around the outer edge of the lamp plate 1000; the annular boss is arranged on the side of the support body close to the light outlet 100a. The cooling member 322 and the conducting member 323 are sleeved on the outside of the annular boss, so as to support and fix the cooling member 322 and the conducting member 323.

[0131] The conducting part 3211 of the cold compress member 321 is covered on the side of the annular boss away from the support body, so as to ensure that the light emitted by the LED lamp beads 1100 and the lamp tube 210 can completely pass through the cold compress member 321 and be emitted from the light outlet 100a, avoiding the problem of light leakage and waste of light. Through the support frame 1200, the number of light can also be increased, and the light emitting brightness can be improved.
