[0038] Embodiment 1
[0039] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a beauty device power-on control circuit, including:
[0040] A control unit 10, which is used to control the operation of the beauty device;
[0041] A power supply unit 11, which is used to supply power to the control unit 10;
[0042] A switching device 12, connected between the control unit 10 and the power supply unit 11. A trigger unit 13 is connected to the switching device 12. When the trigger unit 13 receives a triggering action, the switching device 12 conducts, enabling conduction between the power supply unit 11 and the control unit 10;
[0043] A conduction maintenance unit 20, connected to the switching device 12, and the conduction maintenance unit 20 is used to maintain the switching device 12 in a conducting state when the trigger unit 13 receives a triggering action to make the switching device 12 conduct.
[0044] In this embodiment, by setting the conduction maintenance unit 20, the switching device 12 is maintained in a conducting state when the trigger unit 13 receives a triggering action, thereby ensuring that the beauty device can operate continuously and stably after being powered on, without continuously consuming a large current, thus greatly reducing the power consumption of the power-on control circuit and significantly extending the service life of the battery.
[0045] Specifically, the control unit 10 can adopt an MCU (Micro Control Unit), and the MCU can receive and process various signals and precisely control each functional module of the beauty device. For example, controlling parameters such as the working mode and intensity of the beauty device.
[0046] Furthermore, the power supply unit 11 includes a battery, which is used to provide power for the entire beauty device. Among them, the battery can be a rechargeable battery or a disposable battery, and can be selected according to the usage requirements of the beauty device.
[0047] In one implementation of this embodiment, the switching device 12 is a MOS switch; in the conducting state, the on-resistance of the MOS switch is small, thereby reducing energy loss.
[0048] Further, the triggering unit 13 is a button. The user only needs to press the button to trigger the beauty device to turn on, and it is not easy to cause misoperation, improving the convenience of using the beauty device.
[0049] The conduction maintenance unit 20 includes an auxiliary power supply sub-circuit 21. The auxiliary power supply sub-circuit 21 and the triggering unit 13 are both connected to the gate of the MOS switch; when the triggering unit 13 accepts a triggering action to turn on the MOS switch, the auxiliary power supply sub-circuit 21 raises the gate voltage of the MOS switch, so that the MOS switch remains in the conducting state.
[0050] Since both the auxiliary power supply sub-circuit 21 and the triggering unit 13 are connected to the gate of the MOS switch, when the button is pressed and the triggering unit 13 turns on the MOS switch, the auxiliary power supply sub-circuit 21 raises the gate voltage of the MOS switch, so that the MOS switch remains in the conducting state. The setting of the conduction maintenance unit 20 can ensure the stable operation of the beauty device after it is turned on and prevent it from accidentally turning off due to external interference.
[0051] Specifically, the auxiliary power supply sub-circuit 21 is used to connect to an auxiliary power supply. The auxiliary power supply sub-circuit 21 includes a control feedback pin 22, that is, Figure 2 the VBAT_EN pin in, the gate of the MOS switch is connected to this control feedback pin 22, and the drain of the MOS switch is connected to the power supply terminal of the control unit 10. Based on this, after the triggering action, the auxiliary power supply provides a stable voltage for the gate of the MOS switch through the auxiliary power supply sub-circuit 21 to ensure that the MOS switch remains conducting.
[0052] Please refer to Figure 3 , in another implementation of this embodiment, the switching device 12 is a relay RY, and the conduction maintenance unit 20 includes a self-locking circuit, and the self-locking circuit is connected to the auxiliary contact of the relay RY.
[0053] Further, the self-locking circuit includes a diode Ds and a relay resistance Rs. The diode Ds is connected in parallel to the coil of the relay RY, and the relay resistance Rs is connected between the auxiliary contact and the coil of the relay RY; in addition, a triode switch Qs is connected between the triggering unit 13 and the relay; when the triggering unit 13 accepts a triggering action, the triode switch Qs conducts, causing the relay coil to be energized. Through the mutual cooperation of the diode Ds and the relay resistance Rs in the self-locking circuit, a stable self-locking function can be achieved after the relay coil is energized to ensure the normal operation of the relay RY.
[0054] It can be understood that when the trigger unit 13 receives a trigger action, the relay coil is energized and the auxiliary contact is closed. When the relay coil is energized, the auxiliary contact is closed, enabling the power supply unit 11 to conduct with the control unit 10. The self-locking circuit locks the relay circuit through the auxiliary contact, thereby keeping the relay in a conducting state. At this time, the diode plays a role in protecting the relay coil, preventing reverse current from damaging the coil, and the relay resistor limits the current to ensure the normal operation of the relay.
[0055] Based on the foregoing structure, since the structure of the self-locking circuit is relatively simple, it can improve the maintenance efficiency of faults while providing a stable conduction maintaining effect.
[0056] Embodiment 2
[0057] Based on the foregoing embodiment, this embodiment provides a beauty instrument, including the beauty instrument power-on control circuit provided in the foregoing embodiment.
[0058] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of this application.
