[0062] In one embodiment, the atomizing host 1 further includes a memory 16 connected to the host controller 12. The memory 16 is used to store atomizing host parameters and / or atomizer parameters, such as storing the client program of the electronic atomizing device and data, pictures and other functions of the local device.

[0063] Please refer to Figure 14, which is a flowchart illustrating an atomization control method for an atomizer host in one embodiment. In one embodiment of this application, an atomization control method applied to the atomizer host described above is also disclosed, including:

[0064] Step 301: Determine whether the host connection interface is connected to the atomizer.

[0065] Step 302: If the host connection interface is connected to the atomizer, the atomizer host provides working power to the atomizer and obtains the atomization parameters of the atomizer.

[0066] Step 303: The atomizing host controls the atomizer's atomization operation according to the atomization parameters, wherein the atomization parameters include at least the atomizer model.

[0067] In this embodiment, the atomizing host and atomizer are connected via an adapter. The atomizing host can be connected to atomizers with different functions, flavors, and models by replacing the atomizer. Because the atomizer integrates power supply, atomization control, and heat conversion functions, it can operate independently even without being connected to the atomizing host. When connected to the atomizing host, the host controls the atomization and heat conversion rate, enhancing the functionality of the electronic atomization device accessory and significantly improving the user experience. Furthermore, the atomizing host can output higher power to achieve better atomization results than the atomizer operating alone.

[0068] One embodiment of this application also discloses an electronic atomization device, including an atomizer as described above and an atomization host as described above. As shown in FIG2, the heating unit 23 includes a first heating element 231, which is connected to the atomization circuit 22 and the adapter connection interface 26. When the adapter connection interface 26 is not connected to the atomization host 1, the first heating element 231 obtains electrical energy from the atomization circuit 22, that is, the atomization is controlled by the atomization controller 25. When the adapter connection interface 26 is connected to the atomization host 1, the first heating element 231 obtains electrical energy from the atomization signal, and the host controller 12 controls the frequency, duration, and power of the atomization signal to achieve atomization control of the atomizer. At the same time, the boost circuit 15 outputs boosted charging power (power signal) to the atomization power supply 21 through the adapter connection interface 26 to charge the energy storage battery 211. In one embodiment, the first heating element is a heating wire. The electrical energy provided by the atomizing power supply is less than that provided by the power supply unit. The atomizing power supply ensures that the atomizer achieves its minimum atomization function. After the atomizer is connected to the atomizing host, the power supply unit of the atomizing host provides electrical energy and ensures the best thermal energy conversion efficiency of the first heating element. That is, the output power of the host battery is greater than the output power of the storage battery. In this way, the atomizer will provide the user with a better atomization effect after being connected to the atomizing host.

[0069] As shown in Figure 3, in one embodiment, the heating unit 23 includes a first heating element 231 and a second heating element 232. The first heating element 231 is connected to an adapter connection interface 26. When the adapter connection interface 26 is connected to the atomizing host 1, the first heating element 231 obtains an atomization signal for heat energy conversion. When the adapter connection interface 26 is not connected to the atomizing host 1, the second heating element 232 obtains electrical energy from the atomization circuit 232 for heat energy conversion. That is, when the atomizing host is not connected, the second heating element 232 performs heat energy conversion independently, while when the atomizing host is connected, the first heating element 231 performs heat energy conversion independently. This ensures that the electrical output of the atomizing host and the electrical output of the atomizer are independent and do not interfere with or affect each other. In one embodiment, both the first heating element 231 and the second heating element 232 are heating wires, wherein the heating power of the first heating element 231 is greater than that of the second heating element 232. In one embodiment, when the atomizer is not connected to the atomizing host, it operates in low-power mode only through the first heating element. When connected to the atomizing host, it operates in high-power mode only through the second heating element. In another embodiment, the second heating element, under the control of the atomizing host, can switch between low-power and high-power atomization modes. Furthermore, in the embodiment shown in Figure 5, the atomization control circuit for outputting electrical energy to the first heating element 231 is located on the atomizing host, which can save on atomizer production costs and also allows for independent control of both the first and second heating elements 231 and 232. In one embodiment, the first and second heating elements 231 and 232 can be used in applications involving synchronous or alternating heat energy conversion.

[0070] In Figure 3, since the first heating element 231 and the second heating element 232 are controlled separately by the controllers of the atomizer and the atomizing host, respectively, and the start sensor is integrated into the structure of the atomizer, when the atomizer collects the signal (atomization start electrical signal) from the gas sensor (start sensor), it immediately triggers the atomization circuit 22 inside the atomizer to provide power to the second heating element 232. Then, the atomization start electrical signal, which serves as a communication signal, is simultaneously transmitted to the host controller 12 of the atomizing host 1. After receiving the communication signal, the host controller 12 then activates the atomization control circuit 13 to output an atomization signal to the first heating element 231. In Figure 4, both the first heating element 231 and the second heating element 232 are connected to the adapter connection interface 26. When the adapter connection interface is connected to the atomizing host, the first heating element 231 and the second heating element 232 jointly acquire the atomization signal for heat energy conversion. When the adapter connection interface 26 is not connected to the atomizing host 1, only the second heating element 232 obtains electrical energy from the atomization circuit 22 for heat energy conversion. In other words, when the atomizer operates alone, only the second heating element 232 performs heat conversion. However, when connected to an atomizing host, both the first and second heating elements 231 simultaneously receive the atomization signal and perform heat conversion. This allows for increased heat conversion load to achieve the same heat conversion power when connected to the atomizing host, eliminating the need for differentiated designs for the first and second heating elements 231 and 232, thus reducing the manufacturing process and costs. In Figure 4, when the adapter is connected to the atomizing host, the power supply unit simultaneously supplies power to both the first and second heating elements 231, effectively connecting them in series or parallel. This reduces the atomizer's design complexity and manufacturing costs while ensuring increased heat conversion power.

[0071] In Figure 6, the heat conversion power of the first heating element 231 is greater than that of the second heating element 232. The atomizing circuit 22 includes a first atomizing circuit 221 and a second atomizing circuit 222. The first atomizing circuit 221 is connected to both the first heating element 231 and the adapter connection interface 26. When the adapter connection interface 26 is connected to the atomizing host 1, the first atomizing circuit 221 outputs the atomizing signal obtained from the adapter connection interface 26 to the first heating element 231 for heat conversion. The second atomizing circuit 222 is connected to the second heating element 232, the atomizing power supply 21, and the atomizing controller 25. The second atomizing circuit 222 responds to the first atomizing control electrical signal by outputting electrical energy from the atomizing power supply 21 to the second heating element 232 for heat conversion when the atomizer operates alone. Since an atomizing circuit is set for each of the first heating element 231 and the second heating element 232 in the atomizer, the heat energy transfer load of each of the first heating element 231 and the second heating element 232 can be freely set. When it is necessary to realize the time-sharing asynchronous or synchronous control of the first heating element 231 and the second heating element 232, it is achieved through the first atomizing circuit 221 and the second atomizing circuit 222.

[0072] In one embodiment, when the adapter connection interface 26 is connected to the atomizer 1, the adapter connection interface 26 is also used to transmit the power signal and ground signal output by the atomizer 1. The ground signal serves as the ground loop signal for power and communication signals when the atomizer 1 and atomizer 2 are connected, and the power signal is used to provide charging power to the atomizer 2. The atomizing power supply 21 includes a charging circuit 212 and a storage battery 211. The charging circuit 212 is connected to both the adapter connection interface 26 and the storage battery 211, and is used to output the power signal acquired by the adapter connection interface 26 to the storage battery 211 to charge the storage battery 211. In one embodiment, the power signal is 5V DC.

[0073] In one embodiment, when the charging circuit 212 charges the storage battery, the atomizing power supply 21 stops supplying power to the atomizer 2. As shown in FIG4, in one embodiment, the activation sensor 24 is connected to the adapter connection interface 26. When the atomizing power supply 21 stops supplying power to the atomizer 2, the power signal provides operating power to the activation sensor 24. In one embodiment, when the adapter connection interface 26 is connected to the atomizing host 1, the adapter connection interface 26 is also used to output the atomization activation electrical signal output by the activation sensor 24 as a communication signal to the atomizing host 1, so that the atomizing host 1 can control the heat energy conversion of the heating unit 23 in response to the atomization activation electrical signal.

[0074] In the electronic atomizing device of this application embodiment, when the atomizer and the atomizing host are separated, the atomizer can be used independently. The atomizer is powered by a battery integrated within it, while the integrated atomization circuit, heating unit, start-up sensor, and atomization controller, among other functional modules, are used to achieve atomization. Integrating these functional modules into the atomizer reduces the circuit complexity and product size of the atomizing host, making it more compact and portable without sacrificing functionality. Although the atomizer can be used independently, its power for heat energy conversion for atomization is limited due to size and cost considerations (the atomizer needs to be easily replaceable) (the capacity of the energy storage battery cannot be too large due to size and weight limitations), making it suitable only for low-power applications. For applications requiring high-power heat energy conversion, the atomizer can be mounted on the atomizing host, which provides a high-power power source and can also charge the atomizing battery. The electronic atomizing device disclosed in this application embodiment not only expands the functionality of each accessory but also meets different user needs, greatly improving the user experience.
