AI Technical Summary

Technical Problem

Existing aerosol generating devices have safety issues during battery replacement, especially the risk of the battery coming into contact with control components, and lack protective circuitry.

Method used

An aerosol generating device is designed, wherein the power supply unit has a protection circuit and the intrusion of the power supply unit into the plate receiving portion is restricted by the regulating part of the housing, so as to ensure that the power supply unit is removably arranged in the power supply receiving portion and avoids direct contact with the control elements.

Benefits of technology

This enabled the safe replacement of the power supply unit, improving the safety and reliability of the device.

Abstract

An example inhalation device (100) for an aerosol generating apparatus includes: a power supply unit (111) configured to supply power to a heater unit (60) for heating the aerosol source; a main body side plate unit (90) on which an MCU (1161) controlling the power supply to the heater unit (60) is mounted; and a housing (housing 20) having a power supply receiving portion (200) and a plate receiving portion (210). The housing (20) includes a connecting portion (connecting portion 20x) and a regulating portion (regulating portion 29) to which the power supply unit (111) is connected, and the regulating portion restricts the power supply unit (111) from encroaching into the plate receiving portion (210). When viewed from the power supply receiving portion (200), the regulating portion (29) is arranged at least between the power supply receiving portion (200) and the mounting section of the MCU (1161). The power supply unit (111) has a battery (1111) and a protection circuit including a protection IC (1114) and a switching circuit (1113), and is removably arranged in the power supply housing (200).
