The battery 20 is preferably a high-rate, small-volume battery.
The lamp cap 60 or the housing 10 is provided with an airflow inlet 101 communicated with the inside of the housing 10, the electrical connection assembly 30 is provided with an airflow outlet communicated with the inside of the housing 10, and the airflow inlet 101 and the airflow outlet 102 are communicated to form an airflow channel. Specifically, in the casing 10, gaps are left between the battery 20 and the inner wall of the casing 10, and between the temperature control board 40 and the inner wall of the casing 10, and the airflow inlet 101 and the airflow outlet 102 communicate through the gaps.
The electrical connection assembly 30 is located at one side of the battery 20 and is mounted on the first end of the housing 10. The electrical connection assembly 30 may include a first electrical connector 31, a second electrical connector 32, and an insulator 33.

The first electrical connector 31 is a cylindrical structure with a central passage extending axially through the whole. One end of the first electrical connector 31 can be fitted in the first end of the housing 10 in an interference manner, and a certain space is left between the first electrical connector and the battery 20, so that the short circuit phenomenon caused by the contact between the first electrical connector and the battery is avoided; the other end of the first electrical connector 31 projects out of the housing 10.

The bracket 70 is made of an insulating material, and not only has the functions of fixing the temperature control board 40 and the airflow sensor 50, but also has the functions of isolating the temperature control board 40 from the battery 20, so that the phenomenon that the end of the battery 20 is short-circuited when the temperature control board 40 is pressed against the battery is effectively prevented from shaking or falling.

For example, when the battery 20 is low, the LED lamp flashes, and the power supply device stops supplying power to the atomizer; when the battery capacity is left 20%, the LED lamp is changed in color to prompt the user that the power supply device is about to stop working. When the atomizer actual measurement resistance did not change with initial resistance in the time of predetermineeing, power supply unit judges that the part that generates heat in the atomizer does not belong to the control by temperature change material, and the LED lamp scintillation, power supply unit stops to supply power for the atomizer.

When the temperature control plate 40 detects that the resistance value of the heating component in the atomizer does not change within a preset time, it is determined that the material of the heating component does not belong to the temperature control material, and the power supply device stops supplying power to the atomizer.
The airflow sensor 50 can feed back a voltage signal to the temperature control board 40 according to a negative pressure value in the smoking process of a user, and the temperature control board 40 regulates and controls the variation amplitude of the output power provided to the atomizer according to the voltage signal and the actually measured resistance value. When the smoking speed of a user is reduced, the negative pressure value is smaller, and the actually measured resistance value tends to exceed the target value, so that the output power of the power supply device is reduced to prevent overhigh temperature or overlarge smoke amount from being choked to the user; when the smoking speed of a user is accelerated (the air flow is increased), the negative pressure value is large, the actually measured resistance value is lower than the target value trend, the output power of the power supply device is greatly increased to compensate the heat taken away by the airflow from the heating part of the atomizer, the temperature is ensured to be accurate, the smoke amount in the unit gas volume is ensured to be consistent, and the mouth feel is consistent.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
