Technical Field

[0001] The present invention relates to the technical field of beauty hair removal instruments, and particularly to a negative pressure trigger stable circuit and a red light wave energy hair removal instrument. Background Art

[0002] For a typical hair removal instrument for human body hair removal, after the light wave emitted by the hair removal instrument irradiates the human epidermis to be hair removed, the body hair on the irradiated epidermis is removed. In order to improve the efficiency of light wave hair removal, it is necessary to filter out some wavelengths of the light wave emitted by the hair removal instrument through a filter component, so as to retain light waves of certain specific bands, and use these specific band light waves to remove hair from the human epidermis to achieve the purpose of improving hair removal efficiency.

[0003] However, in the process of using a traditional hair removal instrument, the terminal voltage applied across the xenon light-emitting tube by the energy storage capacitor triggers the emission of the light wave.

[0039] As Figure 1 shown, in one of the embodiments, a negative-pressure trigger stabilization circuit is provided and applied to a hair remover. The hair remover includes a light-emitting module 104. The negative-pressure trigger stabilization circuit includes: a negative-pressure trigger stabilization module 106 and a control module 102. The negative-pressure trigger stabilization module 106 is electrically connected to the control module 102 and the light-emitting module 104 respectively. The control module 102 is electrically connected to the light-emitting module 104. Wherein, the control module 102 is configured to control the negative-pressure trigger stabilization module 106 to provide a negative voltage for triggering the light-emitting module 104 to emit light waves to the light-emitting module 104, and control the light-emitting module 104 to emit light waves.

[0040] When the control module 102 receives a light-emitting signal, it controls the negative-pressure trigger stabilization module 106 to provide a negative voltage for triggering the light-emitting module 104 to emit light waves to the light-emitting module 104, and controls the light-emitting module 104 to emit light waves.

[0041] The negative voltage provided by the negative-pressure trigger stabilization module 106 to the light-emitting module 104 is an instantaneous pulse voltage. Through this negative voltage, the light-emitting module 104 is triggered to emit light waves. The negative voltage provided by the negative-pressure trigger stabilization module 106 enables the light-emitting module 104 to emit light waves in a timely manner, and the power of the emitted light waves is stable.

[0042] As Figure 2 shown, in one embodiment, the negative-pressure trigger stabilization circuit further includes an energy storage module 108. The energy storage module 108 is electrically connected to the light-emitting module 104 and the control module 102 respectively. The control module 102 is further configured to control the energy storage module 108 to provide a light-emitting voltage for the light-emitting module 104 to emit light waves. Among them, the energy storage module 108 includes an energy storage capacitor.

[0043] During the triggering process, the voltage provided by the energy storage module 108 to the light-emitting module 104 and the instantaneous voltage provided by the negative-pressure trigger stabilization module 106 to the light-emitting module 104 together trigger the light-emitting module 104 to emit light waves. After the triggering is completed, the pulse voltage provided by the negative-pressure trigger stabilization module 106 to the light-emitting module 104 becomes zero, and the voltage provided by the energy storage module 108 to the light-emitting module 104 provides the light-emitting power for the light-emitting module 104 to emit light waves until the light-emitting module 104 stops emitting light waves.

[0044] In one embodiment, the control module 102 is further used to control the energy storage module 108 to stop providing the light-emitting voltage to the light-emitting module 104 when receiving a stop light-emitting signal.

[0045] In one embodiment, the negative voltage provided by the negative-pressure trigger stabilization module 106 for triggering the light-emitting module 104 to emit light waves is twice the light-emitting voltage provided by the energy storage module 108 to the light-emitting module 104 for emitting light waves. For example, the light-emitting voltage is 300V and the negative voltage is 600V.

[0046] As Figure 2 shown, in one embodiment, the negative-pressure trigger stabilization circuit further includes a power supply module 110. The power supply module 110 is electrically connected to the light-emitting module 104, the negative-pressure trigger stabilization module 106, the energy storage module 108, and the control module 102 respectively. The power supply module 110 is used to provide a working voltage to the control module 102. The power supply module 110 is further used to provide a trigger voltage for triggering the light-emitting module 104 to emit light waves to the light-emitting module 104. The control module 102 is used to send an energy storage signal to the power supply module 110. When the power supply module 110 receives the energy storage signal, it provides power to the energy storage module 108 and the negative-pressure trigger stabilization module 106 respectively.

[0047] During the process of the power supply module 110 supplying power to the energy storage module 108, the energy storage module 108 converts the received power into an energy storage voltage, and then supplies the energy (i.e., luminous power) required to emit light waves to the light emitting module 104 under the control of the control module 102. During the process of the power supply module 110 supplying power to the negative pressure trigger stabilization module 106, the negative pressure trigger stabilization module 106 stores the received power as a voltage for providing the terminal voltage required to trigger the light emitting module 104 to emit light waves under the control of the control module 102.

[0048] In one embodiment, the power supply module 110 is used to convert an AC power supply into a DC power supply.

[0049] In one embodiment, the power supply module 110 converts a 220V AC power supply into a 12V DC power supply.

[0050] In one embodiment, there is an energy storage voltage adjustment circuit between the power supply module 110 and the energy storage module 108. The energy storage voltage adjustment circuit is used to adjust the DC voltage output by the power supply module 110 to the voltage required by the energy storage module 108 and then supply it to the energy storage module 108.

[0051] In one embodiment, the energy storage voltage adjustment circuit is used to adjust the DC voltage output by the power supply module 110 to a voltage of 300V.

[0052] In one embodiment, there is a stable voltage adjustment circuit between the power supply module 110 and the negative pressure trigger stabilization module 106. The stable voltage adjustment circuit is used to adjust the DC voltage output by the power supply module 110 to the voltage required by the negative pressure trigger stabilization module 106 and then supply it to the negative pressure trigger stabilization module 106.

[0053] In one embodiment, the stable voltage adjustment circuit is used to adjust the DC voltage output by the power supply module 110 to a voltage of 300V.

[0054] In one embodiment, the stable voltage adjustment circuit is used to adjust the DC voltage output by the power supply module 110 to a voltage of 600V.

[0055] In one embodiment, the energy storage voltage adjustment circuit and the stable voltage adjustment circuit are the same circuit module.

[0056] In one embodiment, the negative pressure trigger stabilization module 106 at least includes a voltage stabilization component and a first stabilization circuit. The first stabilization circuit has a first input end and a first output end. The first input end is electrically connected to the control module 102, and the first output end is electrically connected to the light emitting module 104. The first stabilization circuit further includes a first switch component, a first capacitor component, and a first control component. Among them, the voltage stabilization component is configured to stabilize the input voltage of the first stabilization circuit. The first switch component is configured to control the on-off between the first stabilization circuit and the light emitting module 104. The first capacitor component is configured to charge and discharge the first stabilization circuit. The first control component is configured to control the power supply to charge the first capacitor component and adjust the voltage of the first output end to a negative voltage when the first capacitor component discharges.

[0057] In one embodiment, the negative pressure trigger stabilization module 106 further includes a second stabilization circuit. The second stabilization circuit has a second input end and a second output end. The second input end is connected to the first output end, and the second output end is electrically connected to the light emitting module 104.

[0058] The second stabilization circuit further includes a second switch component, a second capacitor component, and a second control component. Among them, the voltage stabilization component is configured to stabilize the input voltage of the second stabilization circuit. The second switch component is configured to control the on-off between the second stabilization circuit and the light emitting module 104. The second capacitor component is configured to charge and discharge the second stabilization circuit. The second control component is configured to control the power supply to charge the second capacitor component. The second stabilization circuit is configured to change the voltage of the second output end to an integer multiple of the voltage of the first output end.

[0059] As Figure 3As shown, the first stabilization circuit further includes resistors R2, R4, and R6, the voltage stabilization component is resistor R1, the first switching component is first switching transistor Q1, the first capacitor component is first capacitor C1, and the first control component includes diodes D2 and D3; wherein, one end of the first capacitor C1 is respectively connected to the first input terminal and the cathode of diode D2, and the other end of the first capacitor C1 is respectively connected to the emitter of the first switching transistor Q1 and the anode of diode D3; the anode of diode D2 is connected to the first output terminal; one end of resistor R1 is connected to the first output terminal, and the other end of resistor R1 is connected to the power supply; the cathode of diode D3 is grounded; one end of resistor R2 is connected to the first output terminal, and the other end of resistor R2 is connected to the collector of the first switching transistor Q1; one end of resistor R4 is connected to the base of the first switching transistor Q1, and the other end of resistor R4 is connected to the emitter of the first switching transistor Q1; one end of resistor R6 is connected to the base of the first switching transistor Q1, and the other end of resistor R6 is grounded.

[0060] By adjusting the magnitude of resistor R1, the amount of electric charge stored in capacitor C1 can be correspondingly adjusted. Resistor R1 enables the voltage stored in capacitor C1 to reach a set value. Through diodes D2 and D3, the power supply HIV of the negative voltage trigger stabilization module 106 performs forward charging on capacitors C1 and C2, and does not charge negatively.

[0061] When the first input terminal receives a control signal sent by the control module 102 to control the negative voltage trigger stabilization module 106 to provide a negative voltage to the light-emitting module 104, the voltage of the end of capacitor C1 connected to the cathode of diode D2 is zero, and the other end of capacitor C1 is a negative voltage. The first switching transistor Q1 conducts, and the voltage of the first output terminal is adjusted to a negative voltage. The anode of diode D2 is a negative voltage and the cathode is zero, so that capacitor C1 discharges through the first switching transistor Q1, resistor R2, and the first output terminal.

[0063] When the second input terminal receives the negative voltage output from the first output terminal, the voltage of the end of the capacitor C2 connected to the cathode of the diode D1 is zero, and the other end of the capacitor C2 is a negative voltage. The second switching transistor Q2 is turned on, and the voltage of the second output terminal is adjusted to a negative voltage. The anode of the diode D1 is a negative voltage and the cathode is zero, so that the capacitor C2 discharges through the second switching transistor Q2, the resistor R3, and the second output terminal, providing a negative voltage to the light-emitting module 104. The voltage of the second output terminal is the negative of the sum of the voltages of the capacitor C1 and the capacitor C2.

[0064] In one embodiment, the negative voltage trigger stabilization module 106 further includes a resistor R8 and a diode D5. The anode of the diode D5 is connected to the light-emitting module 104, and the cathode of the diode D5 is grounded; one end of the resistor R8 is connected to the second output terminal, and the other end of the resistor R8 is connected to the light-emitting module 104. The resistor R8 plays a role in voltage buffering to prevent the negative voltage trigger stabilization module 106 from discharging too much instantaneously and damaging the light-emitting module 104. The resistor R8 with different resistance values can be selected according to actual needs, for example, R8 = 200 KΩ.

[0065] In one embodiment, the resistance values of the resistors R2 and R3, R4 and R5, and R6 and R7 are the same, the parameters of the diodes D1 and D2, and D3 and D4 are the same, and the parameters of the capacitors C1 and C2 are the same. For example, R2 = R3 = 1 KΩ, R4 = R5 = 1 KΩ, R6 = R7 = 100 KΩ can be selected; the diodes D1 and D2 are selected as diodes of the same model, the diodes D3 and D4 are selected as diodes of the same model, and the capacitors C1 and C2 are selected as capacitors of the same model.

[0066] In one embodiment, the first switching transistor Q1 and the second switching transistor Q2 are triode or field effect transistors. For example, both the first switching transistor Q1 and the second switching transistor Q2 are PNP transistors, the first switching transistor Q1 is an NPN transistor, and the second switching transistor Q2 is a PNP transistor; or the first switching transistor Q1 is a PNP transistor and the second switching transistor Q2 is an NPN transistor. The connection relationship of the first switching transistor Q1 and the second switching transistor Q2 in the negative voltage trigger stabilization module 106 refers to the description of the first switching transistor Q1 and the second switching transistor Q2 above, which will not be elaborated here.

[0067] In one embodiment, the negative voltage trigger stabilization module 106 further includes a third switching transistor Q3. The input end of the third switching transistor Q3 is connected to the first input end of the first stabilization circuit. The control end of the third switching transistor Q3 is connected to the control module 102, and the output end of the third switching transistor Q3 is grounded.

[0068] In one embodiment, the third switching transistor Q3 is an NPN transistor or a PNP transistor.

[0069] In one embodiment, the third switching transistor Q3 is an NMOS field effect transistor or a PMOS field effect transistor. In other embodiments, the third switching transistor Q3 can be selected as other switching devices controlled by IO output.

[0070] Refer to Figure 3 , taking the power supply HIV of the negative voltage trigger stabilization module 106 being equal to the light emitting voltage provided by the energy storage module 108 to the light emitting module 104 as an example. When the third switching transistor Q3 is turned off, the light emitting module 104, that is, the light emitting diode, does not emit light. At this time, the power supply HIV charges the capacitors C1 and C2. The upper plates of the capacitors C1 and C2 carry positive charges and the lower plates carry negative charges. When the charging is completed, the voltages of the capacitors C1 and C2 are VC1 = VC2 = HIV. When the third switching transistor Q3 is turned on, the upper plate of the capacitor C1 is at 0 potential and the lower plate is at -HIV. The first switching transistor Q1 is turned on to generate a pulse. Through the resistor R2, the upper plate of the capacitor C2 becomes -HIV and the lower plate becomes -2HIV. The second switching transistor Q2 is turned on. The voltage -2HIV of the lower plate of the capacitor C2 is applied to the negative electrode of the light emitting diode through the resistor R3. The voltage applied between the positive electrode and the negative electrode of the light emitting diode by the energy storage module 108 is HIV. The voltage between the positive electrode and the negative electrode of the light emitting diode is HIV - (-2HIV) = 3HIV. That is, at the moment when the light emitting diode is triggered, the voltage between the positive electrode and the negative electrode of the light emitting diode is 3HIV. Through the negative voltage trigger stabilization module 106, the voltage between the positive electrode and the negative electrode of the light emitting diode is increased by two times, making it easier for the light emitting diode to be triggered, capable of emitting light waves in a timely manner, and the power of the emitted light waves is stable.

[0071] The above negative pressure trigger stabilization circuit is applied to a hair removal device, which includes a light emitting module. The negative pressure trigger stabilization circuit includes a negative pressure trigger stabilization module and a control module. The negative pressure trigger stabilization module is electrically connected to the control module and the light emitting module respectively, and the control module is electrically connected to the light emitting module. Wherein, the control module is configured to control the negative pressure trigger stabilization module to provide a negative voltage for triggering the light emitting module to emit light waves to the light emitting module, and control the light emitting module to emit light waves. In the present application, the control module controls the negative pressure trigger stabilization module electrically connected to the light emitting module to provide a negative voltage for triggering the light emitting module to emit light waves. Compared with triggering the light emitting module to emit light waves by the terminal voltage applied across the light emitting module through an energy storage capacitor, the light emitting module in the present application is more likely to emit light waves, and the emitted light waves are stable.

[0072] In one embodiment, a red light wave energy hair removal device is provided. The red light wave energy hair removal device has the negative pressure trigger stabilization circuit described in any one of the above. The red light wave energy hair removal device further includes a light filtering module, and the light filtering module is arranged between the light emitting module and the light outlet; the light filtering module is configured to filter out light waves with a wavelength below 640 nm and irradiate light waves with a wavelength of 640 nm or above onto the skin to be depilated.

[0073] When performing hair removal on delicate parts of the human body surface, the red light wave energy hair removal device needs to have a small light outlet, and at the same time, it is necessary to reduce the light emitting power of the light waves emitted by the red light wave energy hair removal device to achieve the effect of energy saving with a small light outlet using a relatively small light emitting power. When canceling the use of the small light outlet for hair removal, the light emitting power of the light waves emitted by the red light wave energy hair removal device needs to be restored to the value before the reduction.

[0074] As Figure 4 shown, in one embodiment, the red light wave energy hair removal device further includes a Hall module 112. The Hall module 112 is connected to the control module 102. The Hall module 112 is configured to send a first signal to the control module 102 when the red light wave energy hair removal device is connected to the accessory head.

The control module 102 is further used to control the increase of the light emitting power of the light emitting module 104 when receiving the second signal.

[0075] When the accessory head is connected to the red light wave energy hair removal device, it can reduce the light outlet of the red light wave energy hair removal device. A magnetic pole is provided on the accessory head. When the red light wave energy hair removal device is connected with the accessory head, after the Hall sensor in the Hall module 112 in the hair removal device detects that the hair removal device is connected with the accessory head, it sends a first signal indicating that the hair removal device is connected with the accessory head to the control module 102. After receiving the first signal sent by the Hall module 112, the control module 102 controls to reduce the light emitting power of the light emitting module 104, that is, reduce the energy of the light wave emitted by the hair removal device. When the Hall sensor detects that the hair removal device is separated from the accessory head, the Hall module 112 sends a second signal indicating that the hair removal device is separated from the accessory head to the control module 102. After receiving the second signal sent by the Hall module 112, the control module 102 controls to increase the light emitting power of the light emitting module 104, that is, increase the energy of the light wave emitted by the hair removal device, so that the energy of the light wave emitted by the hair removal device after removing the accessory head is increased to the value before connecting the accessory head.

[0076] When the hair removal device is connected to the accessory head, the control module in the hair removal device can control to reduce the light emitting power of the light emitting module 104 through the Hall module, so as to achieve the purpose of using a smaller light emitting power for a smaller light outlet. When the hair removal device is separated from the accessory head, the control module in the hair removal device can control to restore the light emitting power of the hair removal device through the Hall module, thereby reducing the power consumption of the hair removal device and achieving the effect of energy saving.

One end of the capacitor C3 and the GND end of the chip U1 are both grounded; the other end of the capacitor C3 and the VDD end of the chip U1 are both connected to the power supply V1 of the Hall module 112, and the Vout of the chip U1 is connected to the control module.

[0078] In one embodiment, the Hall module 112 is connected to the power supply module 110 of the hair removal device, and the power supply V1 of the Hall module 112 is provided by the power supply module 110.

[0079] In one embodiment, a voltage adjustment circuit is provided between the power supply module 110 and the Hall module 112, and the voltage adjustment circuit is used to adjust the voltage provided by the power supply module 110 to the voltage required for the operation of the Hall module 112.

[0080] In one embodiment, the power supply V1 of the Hall module 112 is a 3.3-volt DC power supply.

[0081] In one embodiment, the red light wave energy hair removal device further includes a refrigeration module and a body temperature detection module respectively connected to the control module 102; the refrigeration module is configured to reduce the temperature at the contact between the light outlet of the red light wave energy hair removal device and the human skin, and the body temperature detection module is configured to detect the skin temperature at the contact between the light-emitting position of the red light wave energy hair removal device and the human skin. The body temperature detection module is further configured to send the detected skin temperature to the control module, and the control module adjusts the refrigeration power of the refrigeration module according to the skin temperature. During the process of the hair removal device performing hair removal on the human body surface through the refrigeration module and the body temperature detection module, the skin temperature at the hair removal position is within the normal range.

[0082] In one embodiment, the red light wave energy hair removal device further includes a heat dissipation module, and the heat dissipation module is used to reduce the internal temperature of the red light wave energy hair removal device. By means of the heat dissipation module, the internal temperature of the red light wave energy hair removal device is controlled within a certain range, making the operation safer and more convenient.

[0083] The above-mentioned red light wave energy hair removal device has the negative pressure trigger stable circuit described in any one of the above. The control module in the red light wave energy hair removal device of the present application controls the negative pressure trigger stable module electrically connected to the light-emitting module to provide a negative voltage for triggering the light-emitting module to emit light waves to the light-emitting module. Compared with triggering the light-emitting module in the red light wave energy hair removal device to emit light waves by the terminal voltage applied across the light-emitting module through the energy storage capacitor, the light-emitting module in the present application is easier to emit light waves and the emitted light waves are stable.
