Technical Field

The present disclosure belongs to the field of electronic atomization devices, and particularly relates to an electronic atomization device.

Background Art

An electronic atomization device is an electronic product that uses an atomization core to heat and atomize an aerosol matrix into an aerosol state for users to use. At the same time, the aerosol produced by the electronic atomization device does not contain other harmful components such as tar and suspended particulate matter. Therefore, it has a wide application market. Most of the existing electronic atomization devices can only provide one flavor. If consumers want to change to a new flavor, they must buy a whole set of new products, which will cost a lot, and it is not convenient to buy electronic atomization devices with multiple different flavors. Therefore, some electronic atomization devices that can change different flavors have also appeared on the market. However, the operation of this type of electronic atomization device is relatively cumbersome, and the user experience is not high. In addition, a separate child lock button needs to be set to prevent children from misusing it, which increases production costs.

Please refer to Figures 1-9. The electronic atomization device provided in the embodiment of the present disclosure includes a host 1, a top cover 8 rotatably arranged at the upper end of the host 1, and a base 2 rotatably arranged at the lower end of the host 1. The host 1 includes a shell. Several liquid storage tanks 3 are provided in the shell. Airways 4 are provided in the several liquid storage tanks 3. Atomization core 5 is provided in the airway. A battery 6 is also provided in the shell 1. A main board 7 electrically connected to the battery 6 is provided in the base 2. The base 2 is configured to be rotatable so that the battery 6 supplies power to one of the atomization cores 5, or so that the battery 6 does not supply power to several atomization cores 5. The top cover 8 is configured to be rotatable to open one of the airways 4. Through the above structure, in actual applications, the liquid storage tank 3 provided in the shell of the electronic atomization device of the embodiment of the present disclosure is used to store aerosol substrates. Different aerosol substrates can be stored in different liquid storage tanks 3. Exemplarily, different liquid storage tanks 3 can store aerosol substrates of different flavors. When the user needs to use the electronic atomization device, first rotate the base 2 so that the battery 6 supplies power to one of the atomization cores 5 to achieve circuit connectivity. Then rotate the top cover 8 so that the airway 4 corresponding to the atomization core 5 connected to the circuit is opened to achieve airway connectivity. At this time, the atomization core 5 connected to the circuit can heat the aerosol matrix stored in the liquid storage tank 3 and atomize it into a mist-like aerosol. The aerosol flows out along the corresponding airway 4 and can be inhaled by the user. When the user needs to change aerosols of different flavors, it is only necessary to rotate the base 2 so that the battery 6 supplies power to another atomization core 5 to achieve circuit connectivity, and then rotate the top cover 8 so that the corresponding airway 4 is opened to achieve airway connectivity, so that another flavor of aerosol can be finally produced, and the aerosol flows out along the corresponding airway 4 and can be inhaled by the user. The entire conversion process is relatively convenient, and only the base 2 and the top cover 8 need to be rotated. In this way, a multi-flavor electronic atomization device can be realized. If it is not needed, it is only necessary to rotate the base 2 so that the battery 6 does not supply power to several atomization cores 5. Since the base 2 and the top cover 8 need to match each other to achieve the connection between the circuit and the air path, it can prevent children from misusing it and act as a child lock. In addition, during the transportation and storage of the electronic atomization device, the air path can be closed by rotating the top cover 8 to prevent leakage and volatilization of the aerosol matrix.
