It will be understood that "connected" in the following embodiments is to be interpreted as "electrically connected", "communicatively connected", etc. if electrical signals or data is transferred between the connected circuits, modules, units, etc.
In an embodiment, an electronic vaporization device is provided. The electronic vaporization device may be configured to vaporize a liquid substrate. The electronic vaporization device may be applied to different fields such as medical vaporization and electronic vaporization, etc. The electronic vaporization device is configured to store and vaporize a to-be-vaporized substrate to generate an aerosol.

Specifically, the electronic vaporization device includes: a vaporizer 100, a battery 200, and a controller 300. A first electrode 400 and a second electrode 500 that are separable are further arranged between any two of the vaporizer 100, the battery 200, and the controller 300. Generally, a first end of the controller 300 is connected to a first end of the vaporizer 100, a second end of the controller 300 is connected to the positive electrode of the battery 200, a third end of the controller 300 is connected to the negative electrode of the battery 200, and the negative electrode of the battery 200 is further connected to a second end of the vaporizer 100. During specific implementation, other modules or circuit structures may be further connected between the controller 300 and the vaporizer 100, between the controller 300 and the battery 200, and between the battery 200 and the vaporizer 100, which is not limited herein.
Specific manners in which the first electrode 400 and the second electrode 500 that are separable are further arranged between any two of the vaporizer 100, the battery 200, and the controller 300 may include the following manners.
Manner 1: As shown in FIG. 1, the first electrode 400 and the second electrode 500 are located between the vaporizer 100 and the battery 200. By separating the first electrode 400 and the second electrode 500, the vaporizer 100 is powered off during transportation or storage. Therefore, even if the controller 300 senses an atmospheric pressure change through an airflow sensor, because the vaporizer 100 is powered off, the vaporizer 100 does not work or generate heat, which saves power of the battery 200, and can avoid a fire risk caused by continuous heating, thereby improving security during transportation and storage.
Manner 2: As shown in FIG. 2, the first electrode 400 and the second electrode 500 are located between the vaporizer 100 and the controller 300. By separating the first electrode 400 and the second electrode 500, the vaporizer 100 is powered off during transportation or storage. Therefore, even if the controller 300 senses an atmospheric pressure change through an airflow sensor, the vaporizer 100 does not work (or does not receive instructions from the controller 300) or generate heat, which saves power of the battery 200, and can avoid a fire risk caused by continuous heating, thereby improving security during transportation and storage.
Manner 3: As shown in FIG. 3, the first electrode 400 and the second electrode 500 are located between the battery 200 and the controller 300. By separating the first electrode 400 and the second electrode 500, the power supply of the battery 200 to the controller 300 and the vaporizer 100 is disconnected. Therefore, the battery 200 dose not supply power until a user uses the device, thereby improving security during transportation and storage.
In the electronic vaporization device, the circuit can be disconnected between the battery, and the vaporizer or the controller via a separable first electrode and a second electrode, thereby the circuit between the battery and the vaporizer or the controller, or the circuit between the vaporizer and the controller being disconnected. In this way, during a transportation process and storage process, the power consumption of the electronic vaporization device battery can be reduced. This prolongs a service life of the electronic vaporization device after it was purchased by a user. In addition, a vaporizer will not work when the electronic vaporization device senses an atmospheric pressure change in the process of transportation and storage, reducing risks in the transportation and storage process.
In an embodiment, in order to further improve the durability of the electronic vaporization device and implement the charging function of the electronic vaporization device, as shown in FIG. 1, the other end of the vaporizer 100 is connected to the negative electrode of the battery 200 through the first electrode 400 and the second electrode 500 that are separable. When the first electrode 400 and the second electrode 500 are separated, the first electrode 400 may be connected to the positive electrode of an external power supply, the second electrode 500 may be connected to the negative electrode of the external power supply, and the external power supply charges the battery through the controller 300.
Specifically, as an embodiment, an internal structure of the controller 300 may be shown in FIG. 4, and the controller 300 may include: a charge module 310, a control module 320, a first switch 330, a second switch 340, and a switch control module 350.

A first end of the second switch 340 is connected to the positive electrode of the battery 200. A second end of the first switch 330 is connected to a second end of the second switch 340. A first end of the switch control module 350 is connected to a third end of the first switch 330, a second end of the switch control module 350 is connected to a third end of the second switch 340, a third end of the switch control module 350 is connected to a second end of the charge module 310, and a fourth end of the switch control module 350 is connected to a second end of the control module 320. The control module 320 is also connected to an airflow sensor, configured to sense an atmospheric pressure change or an atmospheric pressure change inside an electronic vaporization device. The control module 320 senses the atmospheric pressure change or an atmospheric pressure change through the airflow sensor, turns off the first switch 330 and the second switch 340 through the switch control module 350, outputs the power of the battery 200 to the vaporizer 100, and further makes the vaporizer 100 work. When the external power supply is connected, the charge module 310 turns on the first switch 330 and turns off the second switch 340 through the switch control module 350. In this way, the external power supply charges the battery and the current directions are shown in FIG. 5.
As an embodiment, the first switch 330 and the second switch 340 may both be MOS transistors. As shown in FIG. 6, the first switch 330 is a first MOS transistor, and the second switch 330 is a second MOS transistor.
