[0003] At present, the existing sewing machines lack a delayed start device. When the voltage fluctuates greatly, the existing electronic control PCB boards of the sewing machines are frequently damaged, which increases the maintenance time and affects the overall working time. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a sewing machine with delayed power-on to solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a delayed power-on sewing machine, comprising a PCB board for driving and controlling a sewing device, the PCB board comprising a sewing machine drive control circuit and a delay circuit for delaying power-on of the sewing machine drive control circuit, the sewing machine drive control circuit being provided with a main control chip, and the main control chip being used to control the sewing machine drive control circuit.

[0006] Preferably, the delay circuit includes a delay control chip and a relay, and the delay control chip is used to control the extension time of the delay circuit.

[0007] Preferably, the delay control chip controls the delay circuit for a period of 0 to 10 seconds.

[0008] The beneficial technical effect of the utility model is that the delayed power-on device first controls the power-on time of the sewing machine drive control circuit, thereby preventing the PCB board from being damaged due to voltage fluctuations, reducing the maintenance rate, and increasing the service life of the PCB board.
