Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The aerosol generating device of the embodiment of the invention comprises: atomizer, drain spare, subassembly such as piece generate heat. The tobacco tar can be injected into the atomizer, and the tobacco tar enters the liquid guiding part from the liquid inlet of the liquid guiding part so that the liquid guiding part is wetted, and dry burning is avoided. The heating element is wound on the surface of the liquid guiding element and is arranged in the atomizer.
As shown in fig. 1, a voltage control method according to a preferred embodiment of the present invention includes the following steps:
step S110: and starting the aerosol generating device, and judging whether the resistance between the first electrode and the second electrode is infinite in real time.
After the aerosol generating device is started, the aerosol generating device outputs voltage to the heating part, and the heating part generates heat to evaporate smoke liquid in the liquid guide part to form smoke.
Fig. 2 and 3 show schematic position diagrams of a first electrode and a second electrode of an aerosol generating device of a preferred embodiment, wherein the first electrode 1 and the second electrode 2 are arranged in an atomizer 3 of the aerosol generating device, the atomizer 3 is shown without smoke liquid in fig. 2, and the atomizer 3 is shown with smoke liquid in fig. 3. Because the heating element 4 is also positioned in the atomizer 3, and the height of at least one of the two electrodes is higher than that of the heating element 4, after the aerosol generating device is started, whether the liquid guide element 5 wound by the heating element 4 can be wetted by the smoke liquid can be determined by judging whether the smoke liquid exists between the two electrodes. When no smoke liquid exists between the two electrodes, the resistance between the two electrodes is infinite; otherwise, the resistance between the two electrodes is not infinite.
Preferably, the first electrode is located at a liquid inlet of a liquid guide part of the aerosol generating device, so that misjudgment is avoided.
The real-time judgment can be carried out once every certain preset time. The preset time can be set according to experience and is not too short, so that the frequent judgment is avoided; the length should not be too long to avoid the failure to make a judgment in time. Specifically, the preset time may be set to 1ms, 10ms, 20ms, or the like.
Step S120: and controlling the output voltage of the heating element of the aerosol generating device according to the judgment result.
If the two determination results are two, one is that the resistance between the first electrode and the second electrode is infinite, and the other is that the resistance between the first electrode and the second electrode is not infinite, then according to the two determination results, the voltage may be controlled in the following two ways in step S120:
(1) if the resistance between the first electrode and the second electrode is infinite, the output of the voltage to the heat generating member is stopped.
If the resistance between the first electrode and the second electrode is infinite, then the first electrode and the second electrode can be considered open circuit because there is no electrically conductive smoke liquid between the first electrode and the second electrode. Thus, indicating that there is no smoke liquid in the atomizer. In the case where there is no smoke liquid in the atomizer, if voltage is output to the heat generating member, the heat generating member may be burned or burnt, which may cause safety problems.
(2) And if the resistance between the first electrode and the second electrode is not infinite, outputting voltage to the heating member.
If the resistance between the first electrode and the second electrode is not infinite, then there is a certain resistance between the first electrode and the second electrode because there is electrically conductive smoke liquid between the first electrode and the second electrode. Thus, indicating that there is smoke liquid in the atomizer. It will be appreciated that different formulations of the smoke liquid, and different distances between the two electrodes, will result in different electrical resistances between the two electrodes. Under the condition that the atomizer is filled with smoke liquid, voltage can be output to the heating element, and phenomena such as dry burning and burnt smell cannot be caused. Therefore, if the resistance between the first electrode and the second electrode is not infinite, a voltage can be output to the heat generating member.
Specifically, during practical application, in the hardware setting, aerosol generating device can set up the control panel, and first electrode, second electrode, the piece that generates heat all can be connected with the control panel electricity, and whether resistance between two electrodes is the infinity is directly judged by the control panel, also whether is controlled according to the judged result by the control panel to the piece output voltage that generates heat.
In summary, in the voltage control method according to a preferred embodiment of the present invention, whether the smoke liquid exists in the atomizer is determined by determining whether the resistance between the two electrodes is infinite, so that whether the voltage is output to the heating element can be controlled, the phenomena of dry burning and burning smell caused by outputting the voltage to the heating element under the condition that no smoke liquid exists in the atomizer are avoided, the safety of the aerosol generating device is improved, and the user experience is improved.
Preferably, for whether the resistance between the first electrode and the second electrode is infinite, in addition to the judgment by directly detecting the resistance between the two electrodes, the judging step may judge whether the resistance to ground of the other electrode is infinite by grounding one electrode. Specifically, as shown in fig. 4, the voltage control method according to another preferred embodiment of the present invention includes the following steps:
step S210: and starting the aerosol generating device, and judging whether the ground resistance of the first electrode is infinite in real time.
Wherein the first electrode and the second electrode are arranged as in the above-described embodiment. Except that the second electrode is grounded. The second electrode may be a separate electrode. Furthermore, in a preferred embodiment of the present invention, since the heat generating member is located in the atomizer, and the heat generating member itself is grounded, the second electrode may be the heat generating member. Therefore, only one first electrode is needed to be arranged, and one electrode connected into the atomizer can be omitted. Likewise, the first electrode may preferably be located at a liquid inlet of a liquid guide of the aerosol generating device, thereby being beneficial to avoiding misjudgment.
Since the second electrode is grounded, it is only necessary to determine whether the resistance to ground of the first electrode is infinite. If the resistance to ground of the first electrode is infinite, the resistance between the first electrode and the second electrode is infinite, which indicates that no smoke liquid exists in the atomizer; otherwise, the resistance between the first electrode and the second electrode is not infinite, indicating that there is smoke liquid in the atomizer.
Similarly, the real-time determination may be performed at preset time intervals, which is not described herein again.
Step S220: and controlling the output voltage of the heating element of the aerosol generating device according to the judgment result.
The step is the same as the step S120, if the resistance to ground of the first electrode is infinite, and there is no smoke liquid between the first electrode and the second electrode, the output of the voltage to the heating element should be stopped; if the resistance to ground of the first electrode is not infinite and smoke liquid exists between the first electrode and the second electrode, the voltage is output to the heating element, which is not described herein again.
Specifically, during the actual application, in the hardware setting, aerosol generating device can set up the control panel, and first electrode and the piece that generates heat all can be connected with the control panel electricity, directly judges whether the resistance to ground of first electrode is the infinity by the control panel, also by the control panel according to the control of judged result to the piece output voltage that generates heat.
In summary, in the voltage control method according to another preferred embodiment of the present invention, the second electrode is grounded, and whether the ground resistance of the first electrode is infinite is determined to determine whether there is smoke liquid in the atomizer, so that the voltage output to the heating element can be controlled, the phenomena of dry burning and burning smell caused by the voltage output to the heating element under the condition that there is no smoke liquid in the atomizer are avoided, the safety of the aerosol generating device is improved, and the user experience is improved.
Preferably, for the case that the resistance between the first electrode and the second electrode is infinite, in addition to the above two embodiments, the determining step may determine whether the voltage of the other electrode is decreased by connecting one electrode to ground and connecting a pull-up resistor to the other electrode. Specifically, as shown in fig. 5, the voltage control method according to another preferred embodiment of the present invention includes the following steps:
step S310: and starting the aerosol generating device to obtain the output voltage of the first electrode in real time.
Wherein the first electrode and the second electrode are arranged as in the above-described embodiment. In contrast, the pull-up resistor is connected to the first electrode. The pull-up resistor is also electrically connected with a pull-up resistor power supply. The second electrode is grounded. The second electrode may be a separate electrode. In addition, in a preferred embodiment of the present invention, since the heat generating member is located at the bottom inside the atomizer, and the heat generating member itself is grounded, the second electrode may be the heat generating member. Therefore, only one first electrode is needed to be arranged, and one electrode connected into the atomizer can be omitted. Likewise, the first electrode may preferably be located at a liquid inlet of a liquid guide of the aerosol generating device, thereby being beneficial to avoiding misjudgment.
Through the arrangement of the first electrode and the second electrode, if the resistance between the first electrode and the second electrode is infinite, that is, the first electrode is not connected to a ground resistance, the output voltage of the first electrode is the voltage applied to the pull-up resistance by the pull-up resistance power supply. If the resistance between the first electrode and the second electrode is not infinite, that is, the first electrode is connected to a resistance to ground, the output voltage of the first electrode is a voltage applied to the resistance to ground.
Similarly, the real-time acquisition may be acquired at preset time intervals, and is not described herein again.
Step S320: the magnitude between the output voltage of the first electrode and the voltage threshold is compared.
Specifically, the voltage threshold may be determined in advance. Preferably, the voltage threshold may be a voltage applied to the pull-up resistor by the pull-up resistor power supply. The resistance between the first electrode and the second electrode is not infinite, the first electrode is connected to a ground resistor, the output voltage of the first electrode is the voltage applied to the ground resistor, and at the moment, due to the voltage division effect of the ground resistor and the pull-up resistor, the output voltage of the first electrode is reduced relative to the output voltage of the first electrode when the ground resistor is not connected. Therefore, whether the first electrode is connected to the ground resistance can be determined by comparing the output voltage of the first electrode with the voltage threshold value, so as to determine whether the resistance between the first electrode and the second electrode is infinite.
If the output voltage of the first electrode is not less than the voltage threshold, step S330 is performed. If the output voltage of the first electrode is smaller than the voltage threshold, step S340 is performed.
Step S330: the resistance between the first electrode and the second electrode is determined to be infinite.
Through the step, if the output voltage of the first electrode is not less than the voltage threshold, the first electrode is not connected to the ground resistance, that is, the resistance between the first electrode and the second electrode is infinite.
Step S340: it was determined that the resistance between the first electrode and the second electrode was not infinite.
Through the step, if the output voltage of the first electrode is smaller than the voltage threshold, the first electrode is connected to the ground resistance, namely the resistance between the first electrode and the second electrode is infinite.
Step S350: and controlling the output voltage of the heating element of the aerosol generating device according to the judgment result.
This step is the same as step S120 described above, and different operations are performed according to different determination results of step S330 and step S340. If the output voltage of the first electrode is not less than the voltage threshold value, no smoke liquid exists between the first electrode and the second electrode, and the voltage output to the heating element is stopped; if the output voltage of the first electrode is smaller than the voltage threshold value and smoke liquid exists between the first electrode and the second electrode, the voltage is output to the heating element, and the description is omitted.
Specifically, during practical application, in hardware setting, the aerosol generation device can be provided with a control panel, the first electrode and the heating element can be electrically connected with the control panel, the control panel directly receives the output voltage of the first electrode (for example, the first electrode is connected with an analog input port (AD port) of the control panel), and whether the output voltage of the first electrode is not less than a voltage threshold is judged, and the control panel controls the output voltage of the heating element according to a judgment result.
In summary, in the voltage control method according to another preferred embodiment of the present invention, the pull-up resistor is connected to the first electrode, and the second electrode is grounded, so as to determine whether the output voltage of the first electrode is not less than the voltage threshold, so as to determine whether there is smoke liquid in the atomizer, thereby controlling the output voltage to the heating element, avoiding dry burning and burning smell caused by outputting voltage to the heating element under the condition that there is no smoke liquid in the atomizer, improving the safety of the aerosol generating device, and improving the user experience.
