[0022] As a new technology, electronic atomization devices replace traditional combustion cigarettes by heating tobacco oil or burning cigarettes at low temperatures. Their operating temperature is low, and the smoke they produce contains far fewer harmful substances than traditional combustion cigarettes. Using electronic atomization devices can largely avoid the harmful effects of tobacco on the human body, making them a healthier way of smoking.

[0023] Currently available electronic atomization devices are mainly divided into two types: electronic atomization cigarette devices that vaporize tobacco oil to produce smokable aerosols; and aerosol generators that heat a tobacco aerosol-generating matrix using a low-temperature, non-combustion method to produce smokable aerosols.

[0024] Aerosol generating devices generally use a heater, such as a heating sheet, inserted into an aerosol-generating matrix to heat the matrix, and control the heating temperature to volatilize the components in the aerosol-generating matrix, generating a mist that can be inhaled by humans. The power sources used in the portable, low-temperature firing integrated aerosol generating device systems in the prior art are all lithium-ion batteries, which have problems such as low safety, short service life, and long charging times.

[0025] The present application provides an aerosol generating device that solves the problems of low safety, short service life, long charging time, etc. of the power source used in a portable low-temperature firing integrated equipment system for generating aerosols.

Optionally, in this embodiment, the aerosol generating device 1 may include one heating element 11, one end of which is placed close to the aerosol matrix 15 to fire the aerosol matrix 15 at a low temperature, and the other end of which is connected to the control circuit 12.

[0030] Optionally, in other embodiments, the aerosol generating device 1 may include multiple heating elements 11, which are connected in series or in parallel.

[0031] Specifically, when multiple heating elements 11 are installed in series, one end of each heating element 11 is installed close to aerosol matrix 15, and the other end of each heating element 11 is connected to the other end of the adjacent heating element 11 in order, and the other end of the last heating element 11 is connected to control circuit 12. When multiple heating elements 11 are installed in parallel, one end of each heating element 11 is installed close to aerosol matrix 15, and the other ends of each heating element 11 are all connected to control circuit 12.

[0032] Unlike ordinary capacitors and lithium batteries, the hybrid capacitor 13 in this embodiment has the advantages of a large charge / discharge current and a long lifespan.

[0041] Optionally, in this embodiment, the first capacitor 17 is a normal capacitor with a large capacitance. When the hybrid capacitor 13 supplies power to the first capacitor 17, the first capacitor 17 can store more voltage. Furthermore, when the first capacitor 17 supplies power to the heating element 11, the heating element 11 can maintain its heating time for a longer period of time, thereby extending the usage time of the aerosol generating device 1.
