Embodiment Construction

[0043] Hereinafter, a power supply unit for an aerosol inhaler according to an embodiment of the present invention will be described. First, refer to figure 1 and figure 2 Describes an aerosol inhaler equipped with a power supply unit.

[0044] (aerosol inhaler)

[0045]The aerosol inhaler 1 is an apparatus for inhaling an aromatic aerosol without burning, and has a rod shape extending in a predetermined direction (hereinafter referred to as a longitudinal direction X). In the aerosol inhaler 1, the power supply unit 10, the first case 20 and the second case 30 are provided along the longitudinal direction X in this order. The first case 20 may be attached to and detached from the power supply unit 10 . The second case 30 may be attached to and detached from the first case 20 . In other words, the first cartridge 20 and the second cartridge 30 are replaceable.

Abstract

A power supply unit for an aerosol inhaler, comprising: a first series circuit; a second series circuit, connected in parallel with the first series circuit; a first operational amplifier, including one connected to the first node and the second node a non-inverting input terminal, and an inverting input terminal connected to the other of the first node and the second node; and an adjustment circuit connected to the first operational amplifier and configured to In a state where the potential of the node is lower than that of the node connected to the inverting input terminal, the differential input value of the first operational amplifier is prevented from being equal to the potential of the negative power supply terminal of the first operational amplifier or the minimum value obtainable by the first operational amplifier.

Description

technical field [0001] The present invention relates to a power supply unit for an aerosol inhaler. Background technique [0002] JP-T-2017-501805 (hereinafter referred to as Patent Document 1) discloses a circuit for measuring the resistance value of a heater in a device that generates an inhalable aerosol. [0003] Since the aerosol inhaler is held in the user's mouth when in use, temperature management of the heater used to generate the aerosol is important. There is also a need to improve the efficiency of aerosol generation. [0004] Although the measurement of the resistance value of the heater is disclosed in Patent Document 1, the specific configuration thereof is not disclosed. [0005] An object of the present invention is to provide a power supply unit for an aerosol inhaler that can detect the temperature of a load for generating aerosol with high accuracy. SUMMARY OF THE INVENTION [0006] A first aspect of the present invention relates to a power supply un...
