FIG. 1 is a schematic diagram of an electronic atomization apparatus according to an implementation of this application.
As shown in FIG. 1, the electronic atomization apparatus 100 includes an atomizer 10 and a power supply assembly 20. In a preferred implementation, the atomizer 10 is non-detachably connected to the power supply assembly 20, that is, the electronic atomization apparatus 100 is a disposable apparatus as commonly referred to. Certainly, it is also feasible that the atomizer 10 is detachably connected to the power supply assembly 20.
The atomizer 10 includes a liquid storage cavity (not shown) configured to store an aerosol-forming substrate and a heating element 11. Under the action of the power supplied by the power supply assembly 20, the heating element 11 heats and atomizes the aerosol-forming substrate to form an inhalable aerosol.
In this example, the aerosol-forming substrate is a liquid aerosol-forming substrate, that is, a liquid substrate. The electronic atomization apparatus 100 may further include a liquid transfer unit that is not shown. The liquid transfer unit may be, for example, a cotton fiber, a metal fiber, a ceramic fiber, a glass fiber, or a porous ceramic, which can transmit the liquid aerosol-forming substrate stored in the liquid storage cavity to the heating element 11 through capillary action.
Further, the electronic atomization apparatus 100 further includes a liquid injection port, through which the liquid substrate may be injected into the liquid storage cavity. The structure of the liquid injection port is not limited herein, and reference may be made to the related art.
The power supply assembly 20 includes a battery cell 21 and a circuit 22.

As shown in FIG. 2, the circuit 22 includes a switch circuit 221, a controller 222, an inhalation sensor 223, a charging unit 224, and a detection unit 225.
The switch circuit 221 is configured to turn on or turn off a conductive path between the heating element 11 and the battery cell 21. One electrical connection terminal of the switch circuit 221 is electrically connected to the battery cell 21, the other electrical connection terminal of the switch circuit 221 is electrically connected to the heating element 11, and a control connection terminal of the switch circuit 221 is electrically connected to a port of the controller 222. The control connection terminal of the switch circuit 221 receives a drive signal output by the controller 222. Under the action of the drive signal, the switch circuit 221 intermittently turns on or turns off at a specific frequency, so that the battery cell 21 supplies power to the heating element 11, to further heat and atomize the liquid substrate.
In an example, the controller 222 includes a drive module, and the drive module is electrically connected to the control connection terminal of the switch circuit 221 through a first port of the controller 222. The drive module is configured to output the drive signal to the switch circuit 221, to control the heating element 11 to heat and atomize the liquid substrate. In another example, the drive module may be independent of the controller 222, that is, one end of the drive module is electrically connected to the first port of the controller 222, and the other end is electrically connected to the control connection terminal of the switch circuit 221.
As shown in FIG. 3, in an example, the switch circuit 221 includes a transistor Q1 and a transistor Q2. The transistor Q1 and the transistor Q2 each include a first electrode terminal, a second electrode terminal, and a control terminal. As an example, the transistor Q1 may be a PMOS transistor, and the transistor Q2 may be an NMOS transistor; the first electrode terminal of the transistor Q1 is a drain, the second electrode terminal of the transistor Q1 is a source, and the control terminal of the transistor Q1 is a gate; and the first electrode terminal of the transistor Q2 is a drain, the second electrode terminal of the transistor Q2 is a source, and the control terminal of the transistor Q2 is a gate. The control terminal of the transistor Q2 forms the control connection terminal of the switch circuit 221, and is configured to receive the drive signal from the controller 222 (as shown by OUT_EN in the figure); and the first electrode terminal of the transistor Q2 is electrically connected to the control terminal of the transistor Q1, and the second electrode terminal of the transistor Q2 is connected to ground. The second electrode terminal of the transistor Q1 forms a first electrical connection terminal of the switch circuit 221, and is configured to be electrically connected to the battery cell 21 (as shown by VBAT in the figure); and the first electrode terminal of the transistor Q1 forms a second electrical connection terminal of the switch circuit 221, and is configured to be electrically connected to the heating element 11 (as shown by CON1 in the figure).
The controller 222 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates.

The controller 222 is further configured to obtain a second mode setting signal, and enable the output of the first port of the controller 222 in response to the second mode setting signal.
In this example, when the output of the first port of the controller 222 is disabled, even if the electronic atomization apparatus 100 is being inhaled, the switch circuit 221 cannot receive the drive signal, that is, the switch circuit 221 is prevented from receiving the drive signal. When the first port of the controller 222 is enabled, that is, the switch circuit 221 is allowed to receive the drive signal, the controller can normally output the drive signal to the switch circuit 221 through the first port, to control the heating element 11 to heat and atomize the liquid substrate. For example, if it is detected that the electronic atomization apparatus is being inhaled, the drive signal is output to the switch circuit 221 through the first port.

The inhalation sensor 223 includes, but is not limited to, an airflow sensor, a pressure sensor, or a microphone, which is colloquially referred to as a "mic". The controller 222 is non-responsive to the inhalation signal generated by the inhalation sensor 223 in the first mode, and \responsive to the inhalation signal generated by the inhalation sensor 223 in the second mode to control the switch circuit 221 to turn on or turn off.
The controller 222 further includes a third port electrically connected to the inhalation sensor 223. The controller 222 is configured to disable or enable the output of the first port of the controller 222 when obtaining the inhalation signal output by the inhalation sensor 223.

The charging unit 224 is configured to charge the battery cell 21.
In an example, the charging unit 224 includes a charging interface and a charging control chip. The charging interface is connected to an external power supply, and may be, for example, a common USB interface, a common Type-C interface, a common Lightning interface, a common Micro USB interface, or a common Mini USB interface.
