[0060] In an embodiment, the atomization host 1 further includes a memory 16 connected to the host controller 12. The memory 16 is used to store atomization host parameters and / or atomizer parameters, such as storing client programs of electronic atomization devices and data, pictures, and other functions of local devices.

[0061] Please refer to Figure 14 FIG. 4 is a flowchart of an atomization control method for an atomizer host in an embodiment. In an embodiment of the present application, an atomization control method applied to the atomizer host as described above is also disclosed, which includes:

[0062] Step 301: Determine whether the host connection interface is connected to an atomizer.

[0063] Step 302: If the host connection interface is connected to the atomizer, provide working power to the atomizer by the atomization host, and obtain atomization parameters of the atomizer.

[0064] Step 303: Control the atomization work of the atomizer by the atomization host according to the atomization parameters, wherein the atomization parameters at least include the model of the atomizer.

[0065] In the embodiment disclosed in the present application, the atomization host is adaptively connected to the atomizer. The atomization host can be connected to atomizers of different functions, tastes, and models by replacing the atomizers. Since the atomizer has integrated power supply, atomization control, and heat energy conversion functions inside, the atomizer can work alone even without being connected to the atomization host. When adaptively connected to the atomization host, the atomization and heat energy conversion rate are controlled by the atomization host, so that the functionality of the electronic atomization device accessories is stronger, and the user experience is greatly improved. Further, the atomization host can output higher power to achieve better atomization effect than the atomizer working alone.

[0066] In one embodiment of the present application, an electronic atomization device is also disclosed, including any of the above-mentioned atomizers and any of the above-mentioned atomization hosts. Figure 2 As shown, the heating unit 23 includes a first heating element 231, which is connected to the atomization circuit 22 and the adapter connection interface 26 respectively. When the adapter connection interface 26 is not connected to the atomization host 1, the first heating element 231 obtains power from the atomization circuit 22, that is, the atomization controller 25 controls the atomization. When the adapter connection interface 26 is connected to the atomization host 1, the first heating element 231 obtains power 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 the 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, and the electric energy provided by the atomizing power supply is less than the electric energy provided by the power supply unit. The atomizing power supply ensures that the minimum atomization function of the atomizer is achieved. After the atomizer is connected to the atomizing host, the power supply unit of the atomizing host provides electric 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 energy storage battery. In this way, after the atomizer is connected to the atomizing host, it will provide the user with a better atomization effect.

[0067] like Figure 3 As shown, 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 the adapter connection interface 26. When the adapter connection interface 26 is connected to the atomizer host 1, the first heating element 231 obtains the atomization signal to perform heat energy conversion. When the adapter connection interface 26 is not connected to the atomizer host 1, the second heating element 232 obtains electrical energy from the atomization circuit 232 to perform heat energy conversion. That is, when the atomizer host is not connected, the second heating element 232 performs heat energy conversion alone, and when the atomizer host is connected, the first heating element 231 performs heat energy conversion alone. That is, the electrical energy output of the atomizer host and the electrical energy output of the atomizer are independent of each other and do not interfere with or affect each other. In one embodiment, the first heating element 231 and the second heating element 232 are both heating wires, wherein the heating power of the first heating element 231 is greater than the heating power of the second heating element 232. In one embodiment, when the atomizer is not connected to the atomizer host, the atomizer only performs atomization in low power mode through the first heating element, and when connected to the atomizer host, the atomizer only performs atomization in high power mode through the second heating element. In one embodiment, the second heating element can switch between low power mode and high power mode under the control of the atomizer host. In addition, Figure 5In the embodiment shown, the atomization control circuit for outputting electric energy to the first heating element 231 is arranged on the atomization host, which can save the production cost of the atomizer and also meet the implementation of the independent control function of the first heating element 231 and the second heating element 232. In an embodiment, the first heating element 231 and the second heating element 232 can implement the application scenarios of synchronous heat energy conversion or alternating heat energy conversion.

[0068] In Figure 3 which, since the first heating element 231 and the second heating element 232 are separately controlled by the controller of the atomizer and the atomization host respectively, and the start sensor is integrated in the structure of the atomizer, when the atomizer collects the signal (atomization start electric signal) of the gas sensor (start sensor), the atomization circuit 22 inside the atomizer will immediately provide power supply for the second heating element 232. Then the atomization start electric signal as a communication signal is transmitted to the host controller 12 of the atomization host 1, and the host controller 12 receives the communication signal and then starts the atomization control circuit 13 to output the atomization signal to the first heating element 231.

[0069] In Figure 4 which, the first heating element 231 and the second heating element 232 are connected with the adaptive connection interface 26. When the adaptive connection interface is connected with the atomization host, the atomization signal is acquired by the first heating element 231 and the second heating element 232 together to perform heat energy conversion. When the adaptive connection interface 26 is not connected with the atomization host 1, only the second heating element 232 acquires electric energy from the atomization circuit 22 to perform heat energy conversion. That is, only the second heating element 232 performs heat energy conversion when the atomizer works alone, and when the atomization host is adaptively connected, the first heating element 231 and the second heating element 231 simultaneously receive the atomization signal to perform heat energy conversion, so that the heat energy conversion power when connected with the atomization host can be realized by increasing the heat energy conversion load, and the first heating element 231 and the second heating element 232 do not need to be designed differently, which reduces the production process flow and production cost of the product. In Figure 4 which, when the adaptive connection interface is connected with the atomization host, the power supply unit supplies power to the first heating element 231 and the second heating element 231 at the same time, which is equivalent to connecting the first heating element 231 and the second heating element 232 in series or parallel, so as to reduce the design complexity and production cost of the atomizer under the premise of increasing the heat energy conversion power.

[0070] In Figure 6, the heat energy conversion power of the first heating element 231 is greater than the heat energy power of the second heating element 232. The atomization circuit 22 includes a first atomization circuit 221 and a second atomization circuit 222. The first atomization circuit 221 is connected to the first heating element 231 and the adapter connection interface 26 respectively. When the adapter connection interface 26 is connected to the atomization host 1, the first atomization circuit 221 outputs the atomization signal obtained from the adapter connection interface 26 to the first heating element 231 for heat energy conversion of the first heating element 231. The second atomization circuit 222 is connected to the second heating element 232, the atomization power supply 21 and the atomization controller 25 respectively. The second atomization circuit 222 is used to output the electrical energy output by the atomization power supply 21 to the second heating element 232 in response to the first atomization control electrical signal, so as to be used for heat energy conversion of the second heating element 232 when the atomizer is working alone. Since the first heating element 231 and the second heating element 232 are each provided with an atomization circuit in the atomizer, the heat energy conversion load of the first heating element 231 and the second heating element 232 can be freely set. When time-sharing asynchronous or synchronous control of the first heating element 231 and the second heating element 232 is required, it is achieved through the first atomization circuit 221 and the second atomization circuit 222.

[0071] In one embodiment, when the adapter connection interface 26 is connected to the atomizer host 1, the adapter connection interface 26 is also used to transmit the power signal and common ground signal output by the atomizer host 1. The common ground signal is used as a ground loop signal for the power supply and communication signal when the atomizer host 1 and the atomizer 2 are connected, and the power signal is used to provide charging power to the atomizer 2. The atomizer power supply 21 includes a charging circuit 212 and an energy storage battery 211. The charging circuit 212 is respectively connected to the adapter connection interface 26 and the energy storage battery 211, and is used to output the power signal obtained by the adapter connection interface 26 to the energy storage battery 211 to charge the energy storage battery 211. In one embodiment, the power signal is a 5V DC power supply.

[0072] In one embodiment, when the charging circuit 212 is charging the energy storage battery, the atomizing power supply 21 stops supplying power to the atomizer 2. Figure 4 As shown, in one embodiment, the start sensor 24 is connected to the adapter connection interface 26. When the atomizer power supply 21 stops supplying power to the atomizer 2, the power signal provides operating power to the start sensor 24. In one embodiment, when the adapter connection interface 26 is connected to the atomizer host 1, the adapter connection interface 26 is also used to output the atomization start electrical signal output by the start sensor 24 as a communication signal to the atomizer host 1, so that the atomizer host 1 controls the heat energy conversion of the heating unit 23 in response to the atomization start electrical signal.

[0073] In the electronic atomization device in the embodiments of the present application, when the atomizer and the atomization main machine are separated, the atomizer can be used alone, the power supply of the atomizer is provided by the battery integrated in the atomizer, and various functional modules such as the integrated atomization circuit, the heating unit, the starting sensor and the atomization controller are used to realize the atomization work. Integrating these functional modules into the atomizer can reduce the circuit complexity and the product volume of the atomization main machine, so that the atomization main machine is more exquisite and portable under the premise of not reducing the function. Although the atomizer can be used alone, due to the consideration of the volume and the cost (the atomizer needs to be replaced easily), the power of the heat energy conversion for atomization is limited (the capacity of the energy storage battery cannot be too large due to the limitation of the volume and the weight), which is only suitable for small power demand, and when high-power heat energy conversion is required, the atomizer can be loaded on the atomization main machine, the atomization main machine provides a high-power power supply, and the atomization main machine can also provide a charging power supply to the atomization battery. The electronic atomization device disclosed in the embodiments of the present application not only can expand the functionality of each accessory, but also can meet the different needs of users, greatly improving the user experience.

For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
