It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0038] See Figures 1 to 11 In one embodiment of this utility model, an intelligent voltage output device 100 is provided, comprising:

[0039] The outer shell 10 has an internal cavity 11.

[0040] The fast charging deception module 21 is disposed within the accommodating space 11; the input terminal of the fast charging deception module 21 is used to electrically connect with an external charger and request the external charger 300 to output a corresponding first voltage according to the fast charging protocol; the fast charging deception module 21 obtains the first voltage;

[0041] A boost module 22 is disposed within the accommodating space 11; the input terminal of the boost module 22 is electrically connected to the output terminal of the fast charging inducer module 21, and obtains a first voltage from the fast charging inducer module 21, and performs boost processing on the first voltage to obtain a predetermined second voltage;

[0042] The output terminal line 30 has its input terminal 31 electrically connected to the output terminal of the boost module 22 and obtains a second voltage from the boost module 22; its output terminal 32 is located outside the housing 10 and is used to connect to an external load and provide a second voltage to the external load.

[0043] In this embodiment, a smart voltage output device 100 is provided to enable external chargers such as power banks to power external load devices such as nail lamps for use outdoors. The rated voltage of a nail lamp is typically 24V, higher than the default output voltage of a power bank. The smart voltage output device 100 converts the power bank's output voltage to a voltage suitable for the external load device. The housing 10 of the smart voltage output device 100 has a receiving space 11, within which are mounting slots adapted to the fast charging inducer module 21 and the boost module 22, protecting the fast charging inducer module 21 and the boost module 22 installed within the receiving space 11. Existing standard power banks output 5V by default, but they also support fast charging protocols (e.g., PD2.0, PD3.0, QC2.0, and / or QC3.0). The fast-charging decoy module 21 can communicate with a power bank that supports fast-charging protocols, causing the power bank to output a first voltage. Optionally, the first voltage is 9V to 20V, preferably 9V, 12V, 15V, or 20V. The fast-charging decoy module 21 activates the power output capability of the power bank, allowing the boost module 22 to more efficiently output a second voltage to meet the needs of the external load device. The boost module 22 is electrically connected to the external load device via the output terminal line 30, enabling the external load device to obtain the second voltage (e.g., 12V or 24V) for operation.

[0044] As an optional embodiment, see Figure 1 as well as Figure 4 The fast charging decoy module 21 includes a fast charging decoy chip, which is electrically connected to an external charger via a Type-C port 23. It should be noted that the fast charging decoy module 21 can also be implemented using a fast charging decoy circuit, but using a fast charging decoy chip improves flexibility and reliability. Electrical connection to an external charger via the Type-C port 23 allows for more efficient communication of the fast charging protocol.

[0045] As an optional embodiment, see Figure 4 The voltage level selection pin (MOD) of the fast charging deception chip is connected to a resistor of corresponding value or a corresponding level signal;

[0046] The input terminal of the fast charging decoy chip includes a communication pin, which is electrically connected to the channel configuration pin (CC) of the type-c port 23. The communication pin communicates with the external charger via the channel configuration pin (CC) to implement the fast charging protocol. The communication pin requests the external charger to output the corresponding first voltage based on the resistance value of the resistor connected to the voltage level selection pin (MOD) or the corresponding level signal, according to the fast charging protocol.

[0047] In this embodiment, when the voltage level selection pin (MOD) of the fast charging decoy chip is connected to resistors of different resistance values ​​or different level signals, it can request the power supply to output different first voltages according to the fast charging protocol. For example, when it is necessary to power a nail lamp with a rated voltage of 24V, a resistor with a resistance of 33K is connected to the voltage level selection pin (MOD). At this time, the fast charging decoy chip requests the power supply to output a first voltage of 20V, so that the boost module 22 can efficiently boost the first voltage to a second voltage of 24V.

[0048] As an optional embodiment, see Figure 1 , Figure 8 as well as Figure 9 The housing includes a detachable upper housing 12 and a lower housing 13 for easy maintenance. One end of the housing has a first through hole 14 adapted to the type-c port 23 for easy electrical connection with an external charger. The other end has a second through hole 15 adapted to the output end of the boost module 22 for easy electrical connection with the output terminal line 30. The interface of the input end 31 of the output terminal line 30 is adapted to the output end of the boost module 22, and the interface of the output end 32 of the output terminal line 30 is adapted to the external load device, allowing for flexible connection between the boost module 22 and the external load device.

[0049] As an optional embodiment, see Figure 4 The output of the fast charging decoy chip is connected to the power pin (VBUS) of the type-c port 23 to obtain the first voltage output by the external charger.

[0050] As an optional embodiment, see Figure 5 The boost module 22 includes a boost chip, and the output terminal of the boost chip is provided with an output interface (CON4). The input terminal of the output terminal line 30 is electrically connected to the output interface. The boost module 22 can also be a BOOST boost circuit, but using a boost chip is more stable and reliable, and can also flexibly output a corresponding second voltage.

[0051] As an optional embodiment, see Figure 1 , Figure 10 as well as Figure 11The fast charging deception module 21 and the boost module 22 are soldered onto the PCBA (Printed Circuit Board Assembly) board 20.

[0052] As an optional embodiment, the intelligent voltage output device 100 also includes a power level selection switch 40 for adjusting the output power of the boost module 22 and a controller 50; the controller 50 is soldered onto the PCBA board 20, and the housing 10 has a mounting hole 16 adapted to the power level selection switch 40, the power level selection switch 40 is mounted on the mounting hole 16, and the power level selection switch 40 is electrically connected to the controller 50.

[0053] The controller 50 is electrically connected to the boost module 22; the output terminal of the boost module 22 is electrically connected to the switching transistor.

[0054] The power level selection switch 40 sends a corresponding power level selection signal to the controller 50. The controller 50 sends a corresponding PWM signal to the boost module 22 according to the power level selection signal. The PWM signal controls the on and off of the switching transistor to control the output power of the boost module 22.

[0055] In this embodiment, the user can adjust the output power of the boost module 22 via the power level selection switch 40. The power level selection switch 40 can send different power level selection signals to the controller 50. Each power level selection signal corresponds to a different PWM signal, and different PWM signals have different duty cycles. The PWM signal can control the on / off state of the switching transistor. By using PWM pulse width modulation, the output of the boost module 22 can be changed. The switching transistor can be a MOSFET or a transistor.

[0056] As an optional embodiment, see Figure 1 , Figure 10 as well as Figure 11 The power level selection switch 40 is a toggle switch. When the toggle switch is moved to the corresponding position, it outputs the corresponding power level selection signal to the controller 50.

[0057] In this embodiment, the user can slide the toggle switch to different positions to select the corresponding output power level. An indicator light can also be provided on the housing 10, and the controller 50 can indicate the currently selected power level to the user by controlling the indicator light.

[0058] To achieve the above objectives, see Figure 2This utility model also provides a nail lamp 200, including a nail lamp body 210 and an intelligent voltage output device 100 as described above. The output terminal 31 of the output terminal line 30 of the intelligent voltage output device 100 is electrically connected to the nail lamp body 210, and the nail lamp body 210 receives a second voltage provided by the intelligent voltage output device 100. The voltage value of the second voltage can be selected as 24V.

[0059] It should be noted that the intelligent voltage output device 100 provided in this embodiment of the present invention has the same specific implementation and technical effects as the aforementioned embodiments. For the sake of brevity, any parts not mentioned in the embodiment of the nail lamp 200 can be referred to the corresponding content in the aforementioned embodiments.

[0060] In summary, the present invention provides an intelligent voltage output device and its nail lamp. The intelligent voltage output device includes a housing, a fast charging decoy module, a boost module, and output terminal wires. The housing has an internal receiving space that protects the fast charging decoy module and boost module, which are installed within the receiving space. The input terminal of the fast charging decoy module is used to electrically connect to an external charger (e.g., a power bank). Existing standard power banks output 5V by default, but they also support fast charging protocols (e.g., PD2.0, PD3.0, QC2.0, and / or QC3.0) so that the power bank can output a higher voltage to quickly charge the target device that meets the requirements. The fast-charging decoy module requests a corresponding first voltage (preferably higher than 5V, but 5V is also acceptable) from an external charger according to the fast-charging protocol; the fast-charging decoy module obtains the first voltage; the input terminal of the boost module is electrically connected to the output terminal of the fast-charging decoy module, obtains the first voltage from the fast-charging decoy module, and boosts the first voltage to obtain a predetermined second voltage; the boost module boosts the first voltage to meet the needs of external loads such as nail lamps.
