AI Technical Summary

Technical Problem

In the prior art, the layout of the communication module of the spray generation device on the circuit board is not fully considered, resulting in an inappropriate installation position of the communication module, which affects the performance and reliability of the device.

Method used

A power supply unit is designed, which includes a communication module, a power supply for driving the heater, a controller and a circuit board. Communication modules and integrated circuits are properly arranged on the circuit board to ensure that the communication module is properly distanced from other electronic components, and non-installation areas are reserved on the circuit board to reduce noise interference.

Benefits of technology

By rationally laying out communication modules and integrated circuits, the communication performance and overall reliability of the spray generation equipment are improved, noise interference is reduced, and the stability and efficiency of the equipment are improved.

Abstract

A power source unit 1 of an aerosol generation device is provided with: a communication module 62 for communicating with an external apparatus; a power source 10 for supplying power for driving a heater 25 for heating an aerosol source; a controller 71 for controlling the supply of power from the power source 10 to the heater 25; and a first circuit board 6 that has mounted thereon the communication module 62 as well as integrated circuits 61, 63, 64 and elements 161, 162, 163, 164 that are different from the integrated circuits 63, 64. The distance between the communication module 62 and the integrated circuit 63 or 64 is greater than the distance between the communication module 62 and the element 161, 162, 163 or 164.
