CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202021848691.8, filed with the China National Intellectual Property Administration on Aug. 27, 2020 and entitled “STEAM SUPPLY SYSTEM AND VAPORIZATION DEVICE”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of this application relate to the field of e-cigarettes, and in particular, to a steam supply system and a vaporization device.

BACKGROUND

Manufacturers and smokers have gradually increased requirements on a quality and experience of electronic cigarettes, and the electronic cigarettes are also developing in a direction of intelligence and multi-function.

In an implementation process of the embodiments of this application, it is found that the related art above has at least the following problems: At present, in a smart electronic cigarette/smart vaporizer, a module and a circuit for realizing data collection are usually set in a vaporization device, and a module and a circuit for realizing intelligent analysis and power supply are usually set in a power supply device. Due to a fixed electrical polarity of the module and the circuit, when using the smart electronic cigarette/smart vaporizer, a user needs to insert the vaporization device into the power supply device in a certain direction. To prevent electronic components in the smart vaporizer from being burned due to the reverse insertion by the user, currently, there are mainly two methods to avoid this situation.

One is an electronic steam puffing device provided in the patent application CN106163305A. By arranging a switch circuit inside the vaporization device, which is configured to cut off current transmission to a heating element when transmitting data, a circuit is protected when the vaporization device is inserted reversely. However, this design will cause a complex circuit structure of the vaporization device. The other is to set a fool-proofing structure on a housing, but such a design will force a customer to lower an appearance standard. Adding concave and convex parts to prevent the consumer from reverse insertion operation reduces user experience and usually leads to an increase in a volume of the vaporizer.
