AEROSOL INHALER AND AEROSOL INHALER POWER SUPPLY Russian patent published in 2021 - IPC A61M15/06 A24F47/00 A24F40/53 

FIELD: medical equipment.

SUBSTANCE: inventions group relates to medical equipment, namely to an aerosol inhaler and a power supply unit for an aerosol inhaler. The inhaler has a first branched circuit that includes a load that is configured to heat the aerosol source and whose electrical resistance value is correlated with its temperature, a first resistor and a first node connecting the load and the first resistor in series. The inhaler contains a second branch circuit that includes a second resistor, a third resistor, and a second node in series connecting the second resistor and the third resistor. The second branch circuit is connected in parallel with the first branch circuit. The inhaler includes an operational amplifier, the non-inverting input of which is connected to one of the first node and the second node, and the inverting input is connected to the other of the first node and the second node. The inhaler contains a control device having an upper limit temperature for stopping heating of the load and a lower limit temperature for prohibiting the discharge of electricity to the load. The differential input of the op-amp is greater than the negative input potential of the op-amp, or the minimum value that can be accepted by the op-amp, in the first temperature range containing the upper limit temperature, and is equal to the negative input potential of the op-amp, or the minimum value that can be accepted by the op-amp. in the second temperature range containing the lower limit temperature and different from the first temperature range. The power supply unit of the aerosol inhaler has a power source configured to discharge electricity to the load, which is configured to heat the aerosol-forming source and the value of the electrical resistance of which is correlated with its temperature.

EFFECT: creation of an aerosol inhaler and an aerosol inhaler power unit capable of determining with high accuracy the temperature of the load applied to form the aerosol in a suitable temperature range.
