Embodiments of the present invention

In order to make the purposes and advantages of the embodiments of the present invention easier to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following detailed description of the embodiments of the present invention in the drawings does not limit the scope of protection claimed by the present invention, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Referring to FIG. 1 , it is a schematic flow chart of a control method of an aerosol forming device provided by the present invention. The control method of this embodiment is applied to a control module of an aerosol forming device. In addition, the aerosol forming device also includes components such as a battery and a heating element. The control method of the aerosol forming device specifically includes:

The monitoring end is set to the detection state according to the trigger signal, and the monitoring signal is obtained through the monitoring end; whether the cigarette is inserted is determined according to the monitoring signal; when the cigarette is determined to be in the inserted state, the monitoring end is set to the output control state, and the control signal is output through the monitoring end.

The trigger signal is used to wake up the control module. When the control module wakes up, it will determine whether the cigarette is inserted based on the acquired monitoring signal. Only when it is determined that the cigarette is inserted, it will output a control signal for controlling the heating element to heat the cigarette. In this way, the cigarette can be prevented from being heated when it is not inserted into the aerosol forming device, thereby reducing unnecessary battery power consumption and reducing the risk of damage to the aerosol forming device. In addition, when the trigger signal is not received, the monitoring end is in the output control state and outputs a control signal to prohibit the heating element from heating.

In some embodiments, the monitoring end is an IO interface (Input/Ouput interface) of the processor in the control module, that is, this embodiment realizes the acquisition of monitoring signals and the output of control signals through the same IO interface, saving the IO interface resources of the processor required for the aerosol forming device, and utilizing the IO interface resources more efficiently. There is no need to upgrade the processor of the aerosol forming device with scarce IO interface resources, and the control process of this embodiment can be realized, thereby reducing the difficulty and cost of upgrading and modifying the aerosol forming device.

In some embodiments, the monitoring signal is an electrical signal that changes with the insertion and removal status of the cigarette. Therefore, the monitoring end can determine whether the cigarette is inserted by monitoring the changes in the monitoring signal.

In an optional embodiment, the trigger signal may be input in the following manner: the trigger signal is input via a heating control button of the aerosol forming device. In this embodiment, the user may input the trigger signal by pressing the heating control button.

In another optional embodiment, the trigger signal may be input in the following manner: the trigger signal is input by a gesture sensing module of the aerosol forming device. In this embodiment, the gesture sensing module may trigger the output of the trigger signal according to the user's action, including but not limited to picking up the aerosol forming device, rotating the aerosol forming device, and swinging the aerosol forming device.

Furthermore, in an optional embodiment, the monitoring terminal may be set to a detection state according to the trigger signal in the following manner:

According to the trigger signal, the level of the monitoring terminal is set to the first state to obtain and set the initial level of the monitoring signal, and the monitoring terminal is set to the input state, and then the monitoring terminal is set to the detection state. In this embodiment, the level of the monitoring terminal is set to the first state in order to set a stable voltage value for the monitoring signal so that the monitoring terminal can obtain the monitoring signal, and the initial level of the monitoring signal is set so that the monitoring terminal detects a stable constant level when it is suspended or disturbed, thereby avoiding the situation of misjudging the insertion state of the cigarette, and setting the monitoring terminal to the input state is to prepare for detecting the level change of the monitoring signal. In addition, the first state can be a pull-up state or a pull-down state, which can be specifically determined according to the characteristics of the monitoring signal. For example, when the cigarette is inserted, the monitoring signal is at a high level, then the first state corresponds to the pull-down state, thereby avoiding the control module from misjudging the cigarette as being in the insertion state.

In a specific embodiment, the level of the monitoring terminal can be set to the first state in the following manner:

By using the internal pull-up function of the aerosol forming device, the level of the monitoring end is set to the first state. Specifically, the IO interface of some processors has an internal pull-up function, so the level of the monitoring end can be set by the program of the single-chip microcomputer.

In another specific embodiment, the level of the monitoring terminal can be set to the first state in the following manner:

The monitoring end is pulled up by the pull-up circuit of the aerosol forming device to set the level of the monitoring end to the first state. Specifically, since the IO interface of some processors does not have the internal pull-up or pull-down function, it is necessary to set a pull-up circuit at the monitoring end to achieve the level setting of the monitoring end.

Furthermore, in an optional embodiment, it is possible to determine whether a cigarette is inserted according to the monitoring signal in the following manner:

Determine whether the monitoring signal is less than the preset voltage. If so, the cigarette is judged to be in the inserted state, otherwise, the cigarette is judged to be in the uninserted state. In this embodiment, when the cigarette is inserted, the monitoring signal will be set to a low level. Therefore, when the monitoring signal detected by the monitoring end is less than the preset voltage, it means that the cigarette has been inserted, and the cigarette is judged to be in the inserted state. If the detected monitoring signal is greater than or equal to the preset voltage, the cigarette is judged to be in the uninserted state. Considering that the power supply circuit of the aerosol forming device may fluctuate due to the reduction of battery power, and the inevitable errors in the hardware circuit detection, it is necessary to set the preset voltage to be slightly lower than the internal pull-up voltage value of the IO interface or the pull-up voltage value of the pull-up circuit. In the application example, the internal pull-up voltage value or the pull-up voltage value is generally close to equal to the rated operating voltage of the processor. Therefore, the preset voltage can be set to 0.7 times the rated operating voltage to reduce the probability of misjudgment of the plug-in and unplug status of the cigarette.

Furthermore, in an optional embodiment, when it is determined that the cigarette is not inserted, the next trigger signal input is waited for.

Furthermore, in an optional embodiment, when it is determined that the cigarette is not inserted, the control module outputs a non-insertion prompt signal to control the prompt module of the aerosol forming device to send a reminder message to the user that the cigarette is not inserted.

Furthermore, in an optional embodiment, the monitoring signal may be controlled in the following manner:

The monitoring signal is controlled by the cigarette detection module of the aerosol forming device. Specifically, the cigarette detection module is used to control the level change of the monitoring signal according to the plug-in and pull-out status of the cigarette.

Further, in an optional embodiment, the control signal is a high level or a low level.

In a specific embodiment, the monitoring terminal can output the control signal in the following manner:

According to the setting program, a high level or a low level is output through the monitoring terminal. In this embodiment, based on the setting program, the control signal output by the monitoring terminal can be a continuous high level, a continuous low level, a PWM signal or a digital signal formed by the combination of a high level and a low level, so as to control the operation of the heating module of the aerosol forming device. The specific characteristics of the control signal can be set according to the working principle of the heating module. If the heating module is a module that performs heating after being enabled based on a high level, then the setting program will control the monitoring terminal to output a continuous high level. If the heating module is a module that can work according to a PWM signal and adjust the heating power, then the setting program will control the monitoring terminal to output a PWM signal.

In this embodiment, the control method of the aerosol forming device further comprises the following steps:

According to the control signal, the cigarette is heated by the heating module of the aerosol forming device.

Furthermore, in an optional embodiment, the control method of the aerosol forming device further includes:

When the cigarette is pulled out, the locking module of the aerosol forming device locks the control signal to a set level to prohibit heating of the cigarette. Specifically, in the process of heating the cigarette by the aerosol forming device, there is a possibility that the cigarette is suddenly pulled out or accidentally dropped. When the cigarette is pulled out, the locking module locks the level of the control signal, making the control signal's heating control or heating enabling function invalid, and then immediately stops heating the cigarette. In this way, not only the battery power loss is reduced, but also the dry burning of the heating element can be avoided. In addition, the setting of the set level can be determined according to the control characteristics of the heating module. For example, when the heating module receives a high-level control signal, it performs heating work. Setting the set level to a low level can achieve the effect of prohibiting heating of the cigarette.

FIG2 is a logical structure diagram of the first embodiment of the aerosol forming device of the present invention, wherein the aerosol forming device of the embodiment includes a trigger module 1, a cigarette detection module 2 and a control module 3. Among them, the trigger module 1 is used to input a trigger signal. The cigarette detection module 2 is used to output a monitoring signal according to the plug-in and pull-out status of the cigarette. The control module 3 is used to determine whether the cigarette is inserted according to the monitoring signal; when it is determined that the cigarette is in the inserted state, the monitoring end is set to the output control state, and the control signal is output through the monitoring end.

Further, in an optional embodiment, in combination with the structural diagram of the cigarette detection module 2 shown in FIG3 , the cigarette detection module 2 includes a cavity 21 and a switch unit 22 disposed in the cavity 21. The switch unit 22 controls the monitoring signal according to the plugging and unplugging status of the cigarette in the cavity 21. In this embodiment, the switch unit is controlled to open or close by the insertion or unplugging of the cigarette, and the level control of the monitoring signal is realized based on this.

In an optional embodiment, the control module 3 includes a monitoring terminal connected to the switch unit 22 and monitoring the monitoring signal. Specifically, the monitoring terminal is an IO interface of the processor in the control module 3, which is used to obtain the monitoring signal and output the control signal.

In a specific embodiment, the control module 3 is further used to set the level of the monitoring terminal to the first state through its internal pull-up function according to the trigger signal, and at the same time set the monitoring terminal to the input state, and then set the monitoring terminal to the detection state. In this embodiment, the control module 3 sets the initial level of the monitoring terminal to a high level through the internal pull-up function of its processor, so that when the cigarette is not inserted, the monitoring signal detected by the monitoring terminal is a high level, thereby judging that the cigarette is not inserted. On the contrary, when the cigarette is inserted, the monitoring signal is a low level, thereby judging that the cigarette is inserted.

Further, in an optional embodiment, as shown in combination with FIG. 3 and FIG. 4, the switch unit 22 includes a touch switch 221, an elastic member 222 disposed on the inner wall of the protruding cavity 21, and an anti-interference module 223 for preventing the touch switch 221 from closing and interfering with the voltage of the control signal. The first end of the touch switch 221 is connected to the monitoring end via the anti-interference module 223, and the second end of the touch switch 221 is grounded. The elastic member 222 cooperates with the touch switch 221 to trigger the touch switch 221 when the cigarette is inserted into the cavity 21, so as to lower the voltage of the monitoring signal when the cigarette is inserted.

Furthermore, the elastic member 222 may be a spring, a hose or a spring group. In this embodiment, the elastic member 222 is a spring. After the cigarette is inserted into the cavity 21, the spring will be pressed to deform in the direction of the button of the touch switch 221, and then the touch switch 221 will be pressed to close the touch switch 221. The monitoring end is connected to the ground through the anti-interference module 223 and the touch switch 221, so that the voltage of the monitoring signal is pulled down. At this time, the monitoring end will detect that the voltage of the monitoring signal is less than the preset voltage, thereby judging that the cigarette is in the inserted state. On the contrary, when the cigarette is not inserted into the cavity 21, the spring is not subjected to the pressure and returns to the unstressed state. The touch switch 221 is disconnected because it is not pressed. At this time, the monitoring end detects that the voltage of the monitoring signal is greater than or equal to the preset voltage, thereby judging that the cigarette is not inserted. In addition, the anti-interference module 223 is used to prohibit the touch switch 221 from being directly connected to the control end to avoid setting the high-level control signal output by the monitoring end to a low level when the touch switch 221 is in the closed grounding state.

In a specific embodiment, as shown in FIG4 , the anti-interference module 223 includes a first resistor R1 . One end of the first resistor R1 is connected to the monitoring end, and the other end thereof is connected to the first end of the touch switch 221 to prevent the touch switch 221 from being directly connected to the monitoring end, thereby preventing the closed state of the touch switch 221 from affecting the high-level control signal output by the monitoring end.

Furthermore, in an optional embodiment, as shown in Figure 4, the aerosol forming device further includes a locking module 224. The locking module 224 is connected to the touch switch 221 and the monitoring terminal to lock the control signal to a low level when the cigarette is pulled out.

In a specific embodiment, as shown in FIG4 , the locking module 224 includes a second resistor R2 and a switch tube Q1. The first end of the second resistor R2 is connected to the monitoring end, the second end of the second resistor R2 is connected to the input end of the switch tube Q1 as the control signal output end, the output end of the switch tube Q1 is grounded, and the control end of the switch tube Q1 is connected to the first end of the touch switch 221 to lock the control signal to a low level when the touch switch 221 is turned on. Further, the switch tube Q1 can be an NPN transistor or an NMOS tube. In this embodiment, the switch tube Q1 is an NPN transistor. When the cigarette is inserted, the touch switch 221 is closed, the base of the NPN transistor is grounded, and the NPN transistor is cut off. At this time, the second end of the second resistor R2 is equivalent to being suspended, and the monitoring end can output the control signal as usual through the second resistor R2. When the cigarette is pulled out, the touch switch 221 is opened. If the monitoring end outputs a high-level control signal at this time, under the action of the first resistor R1, the base of the NPN transistor is set to a high level, and the NPN transistor is turned on, so that the second end of the second resistor R2 is grounded, thereby converting the high level output by the monitoring end to a low level, thereby achieving the effect of locking the control signal to a low level. It should be noted that in this embodiment, the control signal is output through the second end of the second resistor R2.

Furthermore, in an optional embodiment, the aerosol forming device further comprises a prompting module 4. The control module 3 is connected to the prompting module 4, so that when the control module 3 determines that the cigarette is not inserted, the prompting module 4 is controlled to issue a non-insertion prompting message.

Furthermore, the prompt module 4 includes at least one of an indicator light and a buzzer. In this embodiment, as shown in FIG4 , the prompt module 4 includes an indicator light LED1 and a fourth resistor R4. The anode of the indicator light is connected to the control module 3 to receive the uninserted prompt signal, and the cathode of the indicator light LED1 is connected to the ground via the fourth resistor R4. When the uninserted prompt signal is at a high level, the indicator light LED1 is lit, and the fourth resistor R4 is used to limit the working current of the indicator light LED1. It can be understood that the control module 3 can control the indicator light LED1 to flash according to the set rules by setting a program, such as controlling the indicator light LED1 to flash 5 times to remind the user that the cigarette is not inserted.

Furthermore, in an optional embodiment, as shown in combination with Figures 2 and 4, the aerosol forming device further comprises a heating module 5. The heating module 5 is connected to the monitoring end to receive and heat the cigarette according to the control signal.

In a specific embodiment, as shown in FIG4 , the heating module 5 includes a signal conversion chip U2 and a power amplifier chip U3. The signal conversion chip U2 is used to receive a control signal and convert the control signal into a power signal; the power amplifier chip U3 is connected to the signal conversion chip U2 to control the cavity 21 to heat the cigarette according to the received power signal.

Further, in an optional embodiment, the trigger module 1 may include a heating control button or a posture sensing module, so that the user can input a trigger signal by pressing a button, picking up the aerosol forming device, rotating the aerosol forming device, or swinging the aerosol forming device. In this embodiment, as shown in FIG4, the trigger module 1 includes a heating control button. One end of the heating control button is connected to the trigger signal input end of the control module 3, and the other end is grounded. The heating control button can be a mechanical button or a capacitive touch button, and the user inputs the trigger signal by pressing the button.

As shown in FIG3 and FIG4 , the working principle of the aerosol forming device is as follows:

When the user presses the heating control button, it is equivalent to inputting a trigger signal through the trigger module 1; after the control module 3 receives the trigger signal, the monitoring end in the control module 3 is set to the internal pull-up input state, which is equivalent to setting the monitoring end to the detection state;

If the cigarette is not inserted into the cavity 21 at this time, the monitoring end will detect that the voltage of the monitoring signal is high, and the control module 3 will therefore determine that the cigarette is not inserted. Then, the control module 3 controls the indicator LED1 to flash according to a set rule, thereby reminding the user that the cigarette is not inserted;

If the cigarette is inserted into the cavity 21 at this time, the cigarette will compress and cause the elastic member 222 to deform, thereby pressing the touch switch 221, so that the touch switch 221 is closed, which is equivalent to connecting the control end to the ground through the first resistor R1, so that the voltage of the monitoring signal is set to a low level, and the control module 3 therefore determines that the cigarette is in the inserted state; then, the control module 3 sets the monitoring end to the output control state, and outputs the control signal to the heating module 5 through the monitoring end, thereby heating the cigarette through the heating cavity 21;

When the heating module 5 is in the heating process, if the cigarette is pulled out, the compressive force of the elastic member 222 disappears and returns to the unstressed state, so that the touch switch 221 returns to the open state. If the monitoring end outputs a high-level control signal at this time, under the pull-up effect of the first resistor R1, the switch tube Q1 is turned on, so that the high-level control signal that should be input to the heating module 5 is set to a low level, which is equivalent to locking the control signal to a low level, thereby immediately stopping the heating module 5 from heating the cigarette;

To sum up, by implementing the technical solution of the present invention, the monitoring signal can be obtained through the monitoring end, and the monitoring signal can be used to determine whether a cigarette is inserted, and the control signal can be output through the monitoring end only when the cigarette is inserted, thereby ensuring that the control is output only when the cigarette is inserted, avoiding the defect of the prior art that the control is output even when there is no cigarette, and has the advantages of energy saving and effective protection of the entire device.
