Taking an electronic element as a resistor for exemplary explanation, as shown in fig. 2, in the detection circuit 70, a first end of the switch component 71 is connected to a first end of the resistor 72, a second end of the switch component 71 is connected to a Ground (GND), the first end of the switch component 71 is further connected to the controller 50, and a second end of the resistor 72 is connected to a power supply Voltage (VCC). It is understood that the power supply voltage is a power supply voltage, the ground terminal is 0V, and a potential difference exists between the power supply voltage and the ground terminal. Based on the structure of the detection circuit 70 in fig. 2, if no smoke is inserted into the heating body 10, the switch assembly 71 is turned on, the level signal is a first level signal, and at this time, the first level signal is a high level signal; if a cigarette is inserted into the heating body 10, the switch assembly 71 is closed, the level signal is a second level signal, and the second level signal is a low level signal. Therefore, after the level signal received by the controller 50 jumps from the first level signal (high level signal) to the second level signal (low level signal), it can be determined that a cigarette is inserted into the heating body 10, and similarly, after the level signal received by the controller 50 jumps from the second level signal (low level signal) to the first level signal (high level signal), it can be determined that the cigarette is pulled out of the heating body 10.
In some embodiments, as shown in fig. 3, in the detection circuit 70, a first terminal of the switch component 71 is connected to a power supply Voltage (VCC), a second terminal of the switch component 71 is connected to a first terminal of the resistor 72, a second terminal of the resistor 72 is connected to a ground terminal (GND), and the second terminal of the switch component 71 is further connected to the controller 50. Therefore, based on the structure of the detection circuit 70 shown in fig. 3, when no smoke is inserted into the heating body 10, the switch assembly 71 is turned on, the level signal is the first level signal, and the first level signal is the low level signal; if a cigarette is inserted into the heating body 10, the switch assembly 71 is closed, the level signal is a second level signal, and the second level signal is a high level signal. Therefore, after the level signal received by the controller 50 jumps from the first level signal (low level signal) to the second level signal (high level signal), it can be determined that a cigarette is inserted into the heating body 10, and similarly, after the level signal received by the controller 50 jumps from the second level signal (high level signal) to the first level signal (low level signal), it can be determined that the cigarette is pulled out of the heating body 10.

In this embodiment, can confirm the plug condition of cigarette through level signal's change, simple structure to only including electronic component and switch module among the detection circuitry, make the electric current among the detection circuitry very little, consequently, also can accurately detect the plug condition of cigarette under the smoking set dormancy condition, need not extra key operation that is used for awakening up the smoking set, not only detect accurate but also the simple operation.
In some embodiments, the heating non-combustible electronic smoking article further includes a cover provided at the insertion hole of the heating body, i.e., at the upper end of the hollow structure, and a sensor. It will be appreciated that the cover can be opened or closed flexibly, the cover covering the insertion hole when the cover is closed to protect the heating body, and the insertion hole being exposed for insertion of a cigarette when the cover is opened. The sensor is used for sensing the state of the cover, which includes a closed state or an open state, i.e., the sensor can sense the opening or closing of the cover. For example, the sensor may be a mechanical switch, a photosensor, or the like. The sensor is connected to the controller so that the controller can receive a sensing signal of the sensor, and it is understood that the sensing signal is used to reflect the state of the cover, which is equivalent to the controller acquiring the state of the cover.
In order to make the smoking set safe heating, if the lid is in the open mode, and when detecting cigarette and inserting the heating member, the controller control heating member heats for the heating does not burn electron smoking set and can heat inserting cigarette voluntarily, can simple and convenient user operation.
If the cover is in a closed state, the controller controls the heating body to stop heating, so that potential safety hazards caused by air heating (smokeless heating) can be effectively avoided, and the safety of the smoking set is improved.
In some embodiments, the controller is configured to wake up periodically, so that the controller can receive the level signal periodically and determine whether a cigarette is inserted according to the change of the level signal, thereby not only influencing detection but also reducing energy consumption.
In some embodiments, the controller is configured to wake up when the level signal changes. Therefore, after the controller receives the level signal which is subjected to jumping, whether cigarettes are inserted or not is determined, the controller is prevented from being in an invalid running state, and energy consumption can be further reduced. It is understood that the wake-up device may be an existing wake-up chip, such AS a three-channel low-power AS3933/PAN3501 low-frequency wake-up chip.
To sum up, this electronic smoking set that does not burn by heating includes switch module and the electronic component of series connection through setting up detection circuitry, and this switch module sets up in the below of heating member, works as cigarette props up and inserts in when in the heating member, cigarette props up and triggers switch module is closed, works as cigarette props up and extracts when in the heating member, cigarette props up and triggers switch module opens, and the controller is connected with detection circuitry, thereby, the level signal of this detection circuitry output is received to the controller, inserts or extracts when cigarette props up can trigger this level signal and change when the heating member, then, can confirm the plug condition of cigarette through level signal's change, simple structure to only including electronic component and switch module in the detection circuitry, make the electric current in the detection circuitry very little, consequently, also can accurate cigarette detect the plug condition under the smoking set dormancy condition, the smoking set is not required to be awakened by extra key operation, so that the detection is accurate and the operation is convenient.
Referring to fig. 4, another embodiment of the present application provides a method for detecting the insertion and extraction of a cigarette, which can be applied to any suitable non-combustible heating electronic smoking set, including a controller, a detection circuit and a heating body, wherein the heating body is a cylindrical hollow structure and is used for baking the cigarette inserted into the heating body. The detection circuit comprises a switch component and an electronic element which are connected in series, the switch component is positioned below the heating body, when a cigarette is inserted into the heating body, the cigarette trigger switch component is closed, and when the cigarette is pulled out of the heating body, the cigarette trigger switch component is opened.
The detection circuit is connected with the controller, so that the controller can acquire the level signal output by the detection circuit.
When the cigarette is inserted into the heating body, the switch component is closed due to the fact that the cigarette extrudes the switch component; when the cigarette is extracted from the heating body, it causes the opening and closing of the switch assembly.
It is understood that, based on the switch component being connected in series with the electronic component on the detection circuit, when the switch component is closed or opened, the level signal output by the detection circuit changes. Because the controller is connected with the detection circuit, the controller receives the level signal output by the detection circuit.

Because the controller is connected with the detection circuit, the controller can receive the level signal output by the detection circuit and can determine whether the cigarette is inserted into the heating body according to the change of the level signal.
In some embodiments, referring to fig. 5, the step S22 specifically includes:
s221: and if the level signal jumps from the first level signal to the second level signal, the controller determines that the cigarette is inserted into the heating body.
S222: and if the level signal jumps from the second level signal to the first level signal, the controller determines that the cigarette is pulled out of the heating body.
It is understood that the first level signal and the second level signal are two different level signals, the first level signal corresponds to the level signal when the switch assembly is opened, and the second level signal corresponds to the level signal when the switch assembly is closed. For example, one of the first level signal and the second level signal is a high level signal, and the other is a low level signal, for example, when the first level signal is a high level signal, the second level signal is a low level signal, and when the first level signal is a low level signal, the second level signal is a high level signal.
If no smoke branch is inserted into the heating body, the switch component is switched on, and the level signal is a first level signal; if a cigarette is inserted into the heating body, the switch component is closed, and the level signal is a second level signal. Therefore, after the level signal received by the controller jumps from the first level signal to the second level signal, a cigarette can be determined to be inserted into the heating body, and similarly, after the level signal received by the controller jumps from the second level signal to the first level signal, the cigarette can be determined to be pulled out of the heating body.
In this embodiment, can confirm the plug condition of cigarette through level signal's change, simple structure to only including resistance and switch module among the detection circuitry, make the electric current among the detection circuitry very little, consequently, also can accurately detect the plug condition of cigarette under the smoking set dormancy condition, need not extra key operation that is used for awakening up the smoking set, not only detect accuracy but also simple operation.
