On/off circuit, semiconductor laser treatment equipment, and power on/off control method

Abstract

The invention discloses an on / off circuit, semiconductor laser treatment equipment and a power on / off control method. The on / off circuit is connected to a battery or an adapter, and includes an on / off control and protection module, a power supply module and a control module; Or the voltage output by the adapter generates the corresponding power supply voltage and samples it, outputs the power supply voltage to the power supply module, and outputs the sampling voltage to the control module; there are buttons in the switch control and protection module, and output the corresponding button signals to the control module according to the pressing operation of the buttons The power supply module generates a power supply voltage according to the power supply voltage to supply power to the control module; the control module judges that the button signal and the sampling voltage meet the startup conditions and performs a delayed startup operation, and when the external adapter is detected, the control switch control protection module stops responding to the button press operation, and Disconnect the connection between the battery and the power supply voltage; the button will not have the problem of poor ignition contact and deformation, ensuring that the machine can be turned on and off normally.

Description

technical field [0001] The invention relates to the technical field of semiconductor laser treatment equipment, in particular to a switch circuit, semiconductor laser treatment equipment and a power switch control method. Background technique [0002] In the prior art, the switch circuit of semiconductor laser treatment equipment often adopts self-locking buttons, such as figure 1 As shown, it is assembled by base 1, spring 3, contact clip 4, push shaft 5 and upper cover 6. When the self-locking button is pressed for the first time, the contact clip 4 contacts the insert 2 on the base 1 to make the self-locking button conduct and maintain (that is, self-locking), and the power supply is directly supplied by the output of the self-locking button. Realize the power-on function; when the self-locking button is pressed again, the contact clip 4 and the insert 2 are released to disconnect and hold the self-locking button, and the power supply stops outputting to realize the shut...
