Description

Technical Field

[0001] The present invention relates to the technical field of medical cosmetic equipment, and in particular to a laser hair removal device based on focused ultrasound and a control method thereof. Background Art

[0002] Since the reform and opening up, various undertakings in our country have developed rapidly, people's living standards have been greatly improved, and everyone's requirements for quality of life have become higher and higher. All kinds of people pay more and more attention to their appearance, especially in the summer when people wear short sleeves and shorts. Excessive hair is a problem that troubles the personal image of some men and women. Therefore, how to quickly and thoroughly remove hair has naturally become a solution to this problem.

[0003] At present, the traditional hair removal methods: shaving, plucking with tape, waxing, electrolysis and ointment have not achieved satisfactory results. Some methods are even counterproductive, making the hair grow thicker and thicker. Due to the development of lasers, their applications in beauty are becoming more and more mature, and laser hair removal has achieved good results in practical applications. The principle of laser hair removal is the selective photothermal effect with biological tissues. The laser with a wavelength in the band where the hair follicle melanin is more sensitive is irradiated to the skin area that needs hair removal. The irradiated target cells are the melanin of the hair follicles. After a specific period of irradiation, the hair follicles absorb the laser energy and are broken up, so that the hair follicles are destroyed and the hair will fall off by themselves. The normal cells nearby do not contain melanin or contain less melanin and will not be affected, so a safe and effective hair removal effect is achieved, and there will be no recurrence.

[0004] Existing home laser hair removal devices use laser irradiation for hair removal. The irradiation source is only a single laser. Therefore, the laser energy used is relatively high. During the hair removal process, users will feel a strong stinging sensation, which will also increase the risk of skin damage and reduce the safety of use.

As shown in the figure, the embodiment of the present invention provides a laser hair removal device based on focused ultrasound, wherein the device includes: a main body shell 10, a power supply component 1, a control component 2, a skin color detection component 3, a touch sensing component 4, a temperature sensor 5, a control chip 11, a laser transmitter 6, a focused ultrasound transmitting component 7, a display component 9 and a heat dissipation component 8.

[0049] The host housing 10 includes a cavity 101 and an emission cavity 102 arranged at the bottom of the host housing 10 and connected to the cavity 101. The host housing 101 is used to install the power supply component 1, the control component 2, the touch sensing component 4, the temperature sensor 5, the control chip 11, the laser emitter 6, the focused ultrasound emission component 7, the display component 9 and the heat dissipation component 8.

[0050] The power supply component 1 is arranged in the cavity 101, and is used to provide the device with DC power with a constant voltage and a constant current. The power supply component 1 includes a power socket 12 and a step-down and current-stabilizing circuit; the power socket 12 is used to connect a transmission line; the step-down and current-stabilizing circuit is used to convert the voltage input by the power socket to output DC power with a constant voltage and a constant current. Specifically, the step-down and current-stabilizing circuit can be a Buck circuit, whose basic feature is a DC-DC conversion circuit, which is used to convert the input AC power into DC power with a constant voltage and a constant current for output, and the output voltage is lower than the input voltage.

[0051] The control component 2 is arranged on the main housing 10, and is used for the user to operate and generate an operation control signal to control the working state of the device. Specifically, the control component can be a micro switch button, a knob or a touch button. The user can press the control component to control the start and stop and working gear of the device, that is, the power of the laser generated by the laser transmitter can be adjusted by the control component, and the power of the ultrasonic wave generated by the focused ultrasonic emission component can be adjusted by the control component. Taking the micro switch button as an example, after the power is turned on, the micro switch button is pressed for the first time, and the micro switch button obtains the operation control signal of turning on the device, the micro switch button is pressed for the second time, and the micro switch button obtains the operation control signal of the first gear, the micro switch button is pressed for the third time, and the micro switch button obtains the operation control signal of the second gear, the micro switch button is pressed for the fourth time, and the micro switch button is pressed for the fifth time. The operation control signal of closing the device is obtained, and the cycle is repeated.

[0052] The skin color detection component 3 is arranged on the main body shell and on the same side as the transmitting chamber, and is used to detect the skin color of the user's skin to obtain skin color detection information and feed it back to the control chip 11. Specifically, the skin color detection component can be a TCS34725 color recognition sensor, and the skin color detection component can obtain the RGB information of the user's skin as skin color detection information. If a user with dark skin uses this device, the risk of damaging the user's skin may increase, so a skin color detection component can be added, and when the user's skin color detection information does not meet the requirements, the user is prohibited from using this device.

[0053] The touch sensing component 4 is arranged on the host housing and on the same side as the transmitting chamber, and is used to sense whether the device is in contact with the user's skin to obtain touch sensing information and feed it back to the control chip 11. Specifically, the touch sensing component includes a capacitive touch sensor and a touch control circuit. The capacitive touch sensor can be made of a flexible printed circuit (FPC) material, and the touch control circuit can use an SGL8022K two-channel touch control chip. When the user's skin contacts the capacitive touch sensor in the touch sensing component, parasitic capacitance will be generated in the area that contacts the skin. The touch control circuit can determine the size of the parasitic capacitance to obtain a judgment result of whether it is in contact with the skin, and use the judgment result as touch sensing information. In order to further increase the safety of the use of this device, the touch sensing information of whether the user's skin contacts the touch sensing component can be obtained through the touch sensing component. Only when the user's skin contacts the touch sensing component can the device be used.

[0054] The laser emitter 6 is arranged in the cavity 101 and is connected to the emission cavity 102, and is used to generate laser with a rated wavelength and a rated pulse width and emit it through the emission cavity 102. The rated wavelength of the laser generated by the laser emitter is 790-830nm, the rated pulse width of the laser is 20-40msec, and the optimal wavelength of the laser is 810nm, which can reduce the risk of skin damage while achieving a better hair removal effect, and improve the user's comfort when using it. Specifically, the laser emitter includes a semiconductor laser emitting unit and a laser driving circuit, and the laser driving circuit is used to drive the semiconductor laser emitting unit to work to generate laser. The laser emitter can irradiate the generated laser to the area to be depilated on the user's skin, so as to irradiate the capsules in the area to be depilated with the laser with the rated wavelength and rated pulse width, so as to achieve a good hair removal effect.

[0055] The emission cavity 102 is a cavity for outputting laser and ultrasonic wave. The emission cavity is a recessed hole at the bottom of the main body shell, and the top of the recessed hole is connected with the inside of the cavity.

[0056] The temperature sensor 5 is disposed on the outer wall of the laser generator, and is used to detect the temperature of the laser generator in real time to obtain temperature information and feed it back to the control chip 11. The temperature sensor can be a DS18B20 temperature sensor.

[0057] The focused ultrasonic emission component 7 is arranged on the inner side wall of the emission cavity 102, and is used to generate ultrasonic waves and emit them along the emission cavity 102 after focusing. The rated frequency of the ultrasonic waves generated by the focused ultrasonic emission component is 2-4MHz. Specifically, the focused ultrasonic emission component includes a focused ultrasonic transducer and an ultrasonic driving circuit. The ultrasonic driving circuit is used to drive the focused ultrasonic transducer to work to generate ultrasonic waves. The focused ultrasonic transducer is a concave self-focusing ultrasonic transducer. The laser generated by the focused ultrasonic transducer is emitted from the through hole opened at the bottom of the focused ultrasonic transducer. The focused ultrasonic transducer can be made of a positive temperature coefficient thermistor (PTC). The generated ultrasonic waves are focused and emitted to the area to be depilated on the user's skin, so that the capsules in the area to be depilated are irradiated with ultrasonic waves of the rated frequency, so as to cooperate with the laser to achieve a good depilatory effect, which is safe and painless, and greatly reduces the safety risks during use.

[0058] The display component 9 is arranged on the main body shell, and is used to visually display the working status of the device. Specifically, the display component 9 can be set to at least four LED lights, that is, Figure 1 The first LED light 91, the second LED light 92, the third LED light 93 and the fourth LED light 94 in the display assembly 9 may be set as an LED liquid crystal display screen. Among them, the first LED light 91 is used to display the prompt information of whether the device is turned on, the second LED light 92, the third LED light 93 and the fourth LED light 94 are not lit at the same time, the second LED light 92 is lit, indicating that the working gear of the device is the 1st gear at this time, the third LED light 93 is lit, indicating that the working gear of the device is the 2nd gear at this time, and the fourth LED light 94 is lit, indicating that the working gear of the device is the 3rd gear at this time.

[0059] The heat dissipation component 8 is arranged in the cavity 101, and is used to cool the cavity. The heat dissipation component includes a heat dissipation fan 81 arranged above the laser emitter 6 and a plurality of heat sinks arranged on the inner wall of the cavity and perpendicular to the inner wall of the cavity. When the temperature information sensed by the temperature sensor exceeds the preset temperature threshold, the heat dissipation fan can be controlled by the control chip to start working, and the hot air contacts the heat sink to conduct the heat in the hot air through the heat sink, thereby enhancing the heat dissipation effect on the cavity. Specifically, the temperature threshold can be configured to be 20-40 degrees Celsius. After starting the heat dissipation fan, the heat dissipation fan can also be adjusted by the control chip to rotate at a speed matching the temperature information.

[0060] In a more specific embodiment, the heat sink 82 is vertically arranged. To further enhance the heat dissipation effect of the heat sink, the heat sink can be vertically arranged. Since the density of hot air is small, the vertical arrangement of the heat sink will not affect the upward circulation of hot air, and can greatly increase the amount of air contacting the heat sink per unit time. The vertical arrangement of the heat sink can increase the circulation of air in the cavity and significantly enhance the heat dissipation effect.

[0061] The control chip 11 is arranged in the cavity 101, and is used to control the touch sensing component, the temperature sensor, the laser transmitter and the focused ultrasonic transmitting component according to the operation control signal to control the working state of the device. Specifically, the control chip can obtain the operation control signal, the skin color detection information, the temperature information and the touch sensing information, and send a control signal to control the laser transmitter 6, the focused ultrasonic transmitting component 7 and the display component 9. The control chip is an STM32 chip. The control chip can be arranged on the same control board with the buck current stabilization circuit, the touch control circuit, the laser drive circuit and the ultrasonic drive circuit, so as to be arranged in the cavity as an integrated circuit.

[0062] The laser hair removal device based on focused ultrasound of the present invention comprises: a main body shell, a power supply component, a control component, a touch sensing component, a temperature sensor, a control chip, a laser transmitter, a focused ultrasound transmitting component, a display component and a heat dissipation component. The laser is generated by the laser transmitter, and the ultrasound is generated by the focused ultrasound transmitting component, so that the laser and the ultrasound cooperate to achieve a safe and painless good hair removal effect; the touch sensing information is obtained by the touch sensing component, and the device is started to work only when the touch sensing information meets the conditions, which can increase the safety of use and achieve good use effect in actual application.

[0063] The embodiment of the present invention further provides a control method, which can be applied to any embodiment of the aforementioned laser hair removal device based on focused ultrasound, and the control method can be implemented by executing a control program stored in a control chip. Figure 5 , Figure 5 The figure is a flow chart of a control method of a laser hair removal device based on focused ultrasound according to the present invention.

[0064] like Figure 5 Said control method comprises steps S110 to S160.

[0065] S110: If an operation control signal for turning on the device is received, drive the display component to display a prompt message indicating that the device has been turned on and obtain the gear position information in the operation control signal.

[0066] If an operation control signal for turning on the device is received, a control signal is sent to drive the display component to display a prompt message that the device has been turned on, and further obtain the gear information in the operation control signal.

[0067] For example, if the display component is four LED lights, the first LED light is lit to display a prompt message that the device has started.

[0068] In addition, before the step of driving the display component to display the prompt information that the device has been turned on and obtaining the gear information in the operation control signal, it is also possible to judge whether the skin color detection information obtained by the skin color detection component is less than the preset skin color threshold; if the skin color detection information is less than the skin color threshold, the step of driving the display component to display the prompt information that the device has been turned on and obtaining the gear information in the operation control signal is executed. The skin color detection component can obtain the RGB information of the user's skin as the skin color detection information, and the skin color threshold is also the preset RGB value. It is judged whether the skin color detection information is less than the preset RGB value. If the skin color detection information is less than the skin color threshold, it indicates that the skin color detection information meets the requirements, and the user can use the device normally, and the step of driving the display component to display the prompt information that the device has been turned on and obtaining the gear information in the operation control signal is executed; if the skin color detection information is not less than the skin color threshold, it indicates that the skin color detection information does not meet the requirements, and the user cannot use the device at this time. At this time, a prompt message that the device cannot be used can be issued through the display component.

[0069] S120, judging whether the touch sensing information obtained by the touch sensing component meets the preset touch condition. The touch sensing component obtains touch sensing information of whether the user's skin contacts the touch sensing component. Specifically, the user's skin contacts the capacitive touch sensor in the touch sensing component, which generates parasitic capacitance in the area that contacts the skin. The touch control circuit can determine the size of the parasitic capacitance to obtain a judgment result of whether the skin is in contact, and use the judgment result as touch sensing information. The touch sensing information is information of whether the skin is in contact. If the touch sensing information is yes, the touch sensing information meets the preset touch condition; if the touch sensing information is no, the touch sensing information does not meet the preset touch condition.

[0070] S130. If the touch sensing information satisfies the touch condition, the laser emitter and the focused ultrasonic emission component are driven to generate laser and ultrasonic waves that match the gear information, and the display component is driven to display the gear prompt information that matches the gear information. If the touch sensing information satisfies the touch condition, the laser emitter and the focused ultrasonic emission component can be started to work. Specifically, according to the acquired gear information, a control signal is sent to the focused ultrasonic emission component to generate ultrasonic waves with a power corresponding to the gear information, and a control signal is sent to the laser emitter to generate a laser with a power corresponding to the gear information. After the laser emitter and the focused ultrasonic emission component are driven to start working, a control signal must also be sent to drive the display component to display the gear prompt information that matches the gear information. After processing an area to be depilated, it can be transferred to the next area to continue processing, that is, return to execute step S120.

[0071] For example, if the display component is four LED lights, the gear information is the first gear, the second LED light is on; the gear information is the second gear, the third LED light is on; the gear information is the third gear, the fourth LED light is on.

[0072] S140, judging whether the temperature information obtained by the temperature sensor exceeds the preset temperature threshold. During the operation of the laser transmitter and the focused ultrasound transmitter assembly, heat is generated, especially the heat generated by the laser transmitter is high. If the heat is not discharged in time, it will affect the normal operation of the device. The temperature information of the laser transmitter can be obtained by real-time detection through the temperature sensor, and it can be judged whether the temperature information exceeds the document threshold.

[0073] S150: If the temperature information exceeds the temperature threshold, the cooling fan is driven to rotate at a speed matching the temperature information. When the temperature information sensed by the temperature sensor exceeds the preset temperature threshold, the cooling fan can be controlled by the control chip to start working, and the hot air contacts the heat sink to conduct the heat in the hot air through the heat sink, so as to reduce the temperature of the laser transmitter and the focused ultrasound transmitter assembly.

[0074] S160: If the operation control signal of the closing device is received, the laser emitter, the focused ultrasound emission component, the display component and the cooling fan are driven to stop working. If the operation component information of the closing device is received, a control signal may be sent to drive the laser emitter, the focused ultrasound emission component, the display component and the cooling fan to stop working.

[0075] The control method of the present invention is applied to the above-mentioned laser hair removal device based on focused ultrasound, and the device includes: a main body shell, a power supply component, a control component, a touch sensing component, a temperature sensor, a control chip, a laser transmitter, a focused ultrasound transmitting component, a display component and a heat dissipation component. The laser is generated by the laser transmitter, and the ultrasound is generated by the focused ultrasound transmitting component, so that the laser and the ultrasound cooperate to achieve a safe and painless good hair removal effect; the touch sensing information is obtained by the touch sensing component, and the device is started to work only when the touch sensing information meets the conditions, which can increase the safety of use and achieve good use effects in actual application.
