[0049] Exemplarily, as Figure 2 shown, the first NMOS transistor is Q1, the charging chip is U1. The voltage input pin VBUS of U1 is connected to the gate of Q1, the source of Q1 is grounded, and the drain of Q1 is connected to the power supply terminal J1. The battery output pin VBAT of U1 is connected to both the battery connection terminal J3 and the first clock connection terminal J4. J3 is connected to the positive pole of the battery, and J4 is connected to the second clock connection terminal (i.e., Figure 3 J5 in

[0050] It is understandable that the clock circuit 210 includes a first diode, an enhancement-mode field-effect transistor, and a voltage regulator chip. The anode of the first diode is connected to the second clock connection terminal and the positive pole of the battery. The cathode of the first diode is connected to the voltage input pin of the voltage regulator chip. The voltage output pin of the voltage regulator chip is connected to the voltage input pin of the control chip 220. The cathode of the first diode is also electrically connected to the input pin of the enhancement-mode field-effect transistor. The output pin of the enhancement-mode field-effect transistor is connected to the voltage input end of the digital tube display circuit 230.

[0051] The enhancement-mode field-effect transistor can meet the high-performance requirements of the digital tube display circuit 230, and the voltage regulator chip can meet the requirement of voltage stability of the control chip 220.

[0054] Through the first triode, the first PMOS transistor, and the switch key pin, it can be realized that when the switch key is in the closed state, the power supply to the digital tube display circuit 230 is stopped.

[0055] Exemplarily, referring to Figure 3 and Figure 4 As shown, the first PMOS transistor is Q3, the control chip 220 is set as U4, the first triode is Q2.

[0056] It can be understood that the control display circuit module 200 further includes a voltage detection circuit. The input end of the voltage detection circuit is connected to the positive pole of the battery, and the output end of the voltage detection circuit is connected to the voltage detection pin of the control chip 220.

[0057] By adding a voltage detection circuit, the battery power can be obtained in real time, so that the digital tube display circuit 230 can be controlled to display the power, improving the convenience of use.

[0058] It is understandable that the voltage detection circuit includes a first resistor, a second resistor, and a first capacitor. The first end of the first resistor is connected to the positive pole of the battery, the second end of the first resistor is connected to the first end of the second resistor, the second ends of the second resistor and the first capacitor are both grounded, and the first end of the first capacitor is connected to the first end of the second resistor and serves as the output end of the voltage detection circuit to be connected to the voltage detection pin of the control chip 220.

[0059] Exemplarily, referring to Figure 4 and Figure 5 as shown, the control chip 220 is set as U4, the first resistor is R45, the second resistor is R46, the first capacitor is C46, R45 and R46 are connected in sequence, the first end of C46 is connected between R45 and R46, so that C46 and R46 are in parallel, and the first end of C46 serves as the output end of the voltage detection circuit to be connected to the voltage detection pin BAT of U4.

[0060] It is understandable that the key circuit module 300 includes a setting key, a down key, an up key, a switch key, a third resistor, a fourth resistor, and a fifth resistor. The first ends of the third resistor, the fourth resistor, and the fifth resistor are respectively connected to the first ends of the up key, the setting key, and the down key. The second ends of the third resistor, the fourth resistor, and the fifth resistor are connected to the first end of the switch key and are connected to the second key connection terminal, and the second ends of the up key, the setting key, the down key, and the switch key are grounded.

[0061] By setting the down key and the up key, the brightness adjustment of the lamp can be realized respectively. By setting the key, the function control of the lamp can be realized. By setting the switch key, the on / off of the nail lamp can be controlled.

[0062] The resistance values of the third resistor, the fourth resistor, and the fifth resistor are different, so that the control chip 220 can detect different signals.

[0063] Exemplarily, referring to Figure 4 and Figure 6 as shown, the second key connection terminal is J7, the setting key, the down key, the up key, the switch key, the third resistor, the fourth resistor, and the fifth resistor are respectively S3, S2, S4, S1, R51, R52, R53.

In some embodiments, such as Figure 7 and 8 as shown, the charging indication pin CHARGE of U1 can be connected to U4 through J6 and J10, so that the battery level can be displayed when the charging state is detected.
