A power tool and a safety control circuit module and a safety control method thereof are provided. The power tool includes a power supply device, a control processing device, a safety control circuit module, and a power output device. The control processing device is electrically connected with the power supply device. The safety control circuit module includes a first switch control circuit, a second switch control circuit, a third switch control circuit, a first resistor, and a first diode. The power output device includes a first power connection terminal and a second power connection terminal. Before switch units of the control circuits are controlled, the control processing device detects whether the switch unit has failed, so as to increase safety.

Power tool and safety control circuit module and safety control method thereof

A battery device includes a battery unit, a temperature port, a temperature sensitive component, a switch component and a battery management unit. The temperature sensitive component senses a temperature of the battery unit, and provides a temperature indication signal at the temperature port. The switch component is electrically connected to the temperature sensitive component. When the battery device operates abnormally, the battery management unit controls the switch component to make the switch component stop provision of the temperature indication signal at the temperature port.

Battery device and battery charging system

A method for controlling a nail-striking operation of an electric nail gun is proposed. The electric nail gun includes a control module and at least one switch. The at least one switch outputs a first switch signal that has a first voltage and a second switch signal that has a second voltage when triggered. The control module set a flag that corresponds to the at least one switch to a predetermined state upon determining that a striking condition is met. The striking condition includes that, for each of the at least one switch, the first switch signal has the first voltage and the second switch signal has the second voltage.

Provided is a control system and method for a power-driven nail gun, which includes a battery, a motor, a flywheel rotating along with the motor, an impacting member receiving kinetic energy of the flywheel and a nail channel providing a channel for a nail to move along therewith when hit by the impacting member. The method includes utilizing a microcontroller to provide a pulse width modulation (PWM) signal for a driving circuit to drive the motor based on the PWM signal; and in response to reaching a target rotation speed by the motor, utilizing the microcontroller to output a corresponding PWM duty to the driving circuit based on the voltage of the battery, to make the motor maintain at the target rotation speed. The nails obtain stable and consistent kinetic energy and stability of nail firing is effectively improved.
