In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a power supply device for supplying power to an aerosol-generating load 1, including: a power supply 2, the power supply 2 including a first power supply unit 21 and a second power supply unit 22; the power supply switch 3 is electrically connected with the aerosol generating load 1 and the power supply 2, and the power supply switch 3 is used for controlling the first power supply unit 21 to supply power alone in the preheating stage or simultaneously supplying power to the aerosol generating load 1 by the first power supply unit 21 and the second power supply unit 22. In the present embodiment, in the preheating stage of the gas mist generating load 1, the power supply switch 3 controls the plurality of power supply units, or the power supply unit having a large instantaneous discharge power supplies power to the gas mist generating load 1, thereby completing the rapid preheating. When entering the temperature maintaining stage, the power supply switch 3 may control the single power supply unit, or the power supply unit with smaller discharge power, to stably supply the aerosol-generating load 1 with a discharge power lower than that in the preheating stage. It is understood that each power supply unit may be composed of a single or multiple sub-power sources, such as a battery, a capacitor, etc., and the present embodiment is not limited thereto. The distinction between the preheating phase and the temperature maintaining phase can be done by a timing method, i.e. the power supply switch 3 switches the power supply unit after the preheating is performed for a corresponding time. In one embodiment, when the pre-heating phase is performed for 15 seconds, the pre-heating is complete and the aerosol-generating load 1 enters the temperature maintenance phase. In other embodiments, the preheating time may be set as needed, which is not limited in this embodiment. Meanwhile, the preheating stage and the temperature holding stage may be divided according to the monitored values of the gas mist generating load 1, such as a temperature value, a voltage value, and a current value. For example, in one embodiment, it may be provided that when the temperature of the aerosol-generating load 1 reaches 380 ℃, the preheating is complete and the aerosol-generating load 1 enters a temperature maintenance phase. In other embodiments, the threshold of the monitoring value may be set as needed, which is not limited in this embodiment.
By adopting the technical scheme, the power supply device in the embodiment provides different required powers for the aerosol generating load at different stages of the aerosol generating load by arranging the plurality of power supply units.

Therefore, it is possible to provide sufficient power to the aerosol generating load 1 in the preheating stage by utilizing the high-power and fast-discharge characteristic of the capacitor, thereby achieving rapid preheating. And the battery type power supply unit does not need to work in the preheating stage, so that the loss of the battery type power supply unit in the preheating stage is avoided, the recycling times of the battery type power supply unit are improved, and the power supply safety is guaranteed. When the aerosol generating load 1 enters the temperature maintaining stage, the power supply switch 3 is switched to the battery type power supply unit to supply power to the aerosol generating load 1, so that the power required by the aerosol generating load in a certain temperature range is supplied, and the capacitive type power supply unit does not work, so that stable power supply in the temperature maintaining stage is guaranteed. The specific specifications of the capacitor and the battery can be set according to actual needs, and the embodiment does not limit the specific specifications.

In the present embodiment, the internal charging management unit 23 can make the battery-type power supply unit store insufficient energy when the capacitive-type power supply unit is in an insufficient energy storage state, and the aerosol-generating load 1 is in a non-preheating stage, such as a temperature maintaining stage, a standby stage, etc., and the capacitive-type power supply unit is charged by using the electric energy stored by the battery-type power supply unit itself, so that the sufficient energy storage state of the capacitive-type power supply unit can be ensured and the electric power level sufficient to provide the energy required by the preheating stage to the aerosol-generating load 1 can be ensured. In an embodiment, after the capacitive power supply unit completes the power supply in the primary preheating stage, if the stored energy is lower than the set range, in the temperature maintaining stage, the battery charging unit supplies power to the aerosol generating load 1, and the internal charging management unit 23 controls the battery power supply unit to charge the capacitive power supply unit until the stored energy of the capacitive power supply unit returns to the set range, so as to ensure that the capacitive power supply unit can provide a sufficient high power level for the aerosol generating load 1 when the capacitive power supply unit is preheated next time.
