[0006] The current capacitance value collected by the capacitance sensor is obtained based on a preset frequency, and the capacitance difference between the current capacitance value and the initial capacitance value is calculated.
[0007] Based on a preset time period, if the capacitance difference meets the first condition, the initial capacitance value is updated to the current capacitance value and the timing is restarted. If the capacitance difference does not meet the first condition but meets the second condition, the power on / off state of the smoking device is switched, the initial capacitance value is updated to the current capacitance value and the timing is restarted. The preset time period is greater than the preset insertion / removal time of the smoking device.

[0011] If so, update the initial capacitance value to the current capacitance value and restart the timer;
[0012] If not, determine whether the capacitance difference is within the preset difference range;
[0013] If so, switch the on / off state of the smoking device, update the initial capacitance value to the current capacitance value, and restart the timer.
[0014] In some embodiments, the preset difference range is determined by the maximum and minimum values of the capacitance difference obtained from several insertion and removal experiments on the smoking device.
[0015] In some embodiments, the preset update threshold is equal to 1 / 2 of the minimum value of the capacitance difference.
[0016] In some embodiments, switching the on / off state of the smoking device includes:
[0017] If the smoking device is in the powered-on state, control the smoking device to switch to the powered-off state;
[0018] If the smoking device is in the off state, control the smoking device to switch to the on state.
[0019] In some embodiments, the method further includes power-on initialization before acquiring the initial capacitance value and triggering timing.
[0020] To solve the above-mentioned technical problems, another technical solution adopted in this application embodiment is: providing a smoking device, including:
[0021] Heating chamber for holding cigarettes;
[0022] A capacitance sensor is disposed on the tube wall defining the heating cavity, and is used to collect the capacitance value of the heating cavity;

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0035] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0036] like Figure 1 As shown, the application structure of the smoking control method includes a smoking device 100 and a cigarette 200, which are adapted for use. The smoking device 100 heats the cigarette 200 to generate smoke for inhalation.
[0037] The smoking device 100 is configured with a heating chamber 11 that can accommodate a cigarette 200. The smoking device 100 includes a capacitance sensor 12, which is disposed on the tube wall that defines the heating chamber 11 and is used to collect the capacitance value of the heating chamber 11.
[0038] The smoking device 100 has a heating chamber 11 at one end, with a top opening through which a cigarette 200 can be inserted or removed. The shape of the heating chamber 11 is adapted to the outer periphery of the cigarette 200. In one example, the smoking device 100 also includes a cover that covers the top opening of the heating chamber 11, serving to waterproof and dustproof the heating chamber 11 when the smoking device 100 is not in use, preventing contamination of the heating chamber 11.
[0039] As one example, the capacitance sensor 12 is disposed on the outer wall of the heating chamber 11. When the cigarette 200 is inserted into or removed from the heating chamber 11, the capacitance value collected by the capacitance sensor 12 changes. In some embodiments, the capacitance sensor 12 may be disposed on the inner wall of the heating chamber 11 or at the bottom of the heating chamber 11.
[0040] The cigarette 200 includes a tobacco section, a blocking section, a cooling section, and a mouthpiece section. Common cigarette 200s are cylindrical. In one example, the cigarette 200 is malleable; during insertion into the heating chamber 11, it is subjected to pressure from the inner wall of the heating chamber 11, causing the shape of the cigarette 200 to conform to the shape of the heating chamber 11, thus resulting in more uniform heating of the cigarette 200.
[0041] When inhaling, insert the cigarette 200 into the top opening of the heating chamber 11 until it touches the bottom of the heating chamber 11, completing the insertion process of the cigarette 200. The tobacco section of the cigarette 200 is located inside the heating chamber 11. The heating component inside the smoking device 100 heats the tobacco section of the cigarette 200 to generate smoke for inhalation. The mouthpiece of the cigarette 200 extends out of the heating chamber 11 for the user to take and inhale. When finishing inhaling, pull the cigarette 200 out of the top opening of the heating chamber 11 until the cigarette 200 is completely removed from the heating chamber 11, completing the removal process of the cigarette 200.
[0042] It is understandable that the insertion and removal of cigarette 200 require a certain amount of time. That is, the insertion and removal of cigarette 200 are not considered an instantaneous action.
[0043] Please see Figure 2 This is a flowchart illustrating a smoking device control method provided in an embodiment of this application. Figure 2 As shown, the smoking control method is applied to, for example Figure 1 During the use of the smoking device 100 shown, the smoking device control method includes:
[0044] Step S10: Obtain the initial capacitance value and trigger timing. The initial capacitance value is the capacitance value collected by the capacitance sensor when no cigarette is inserted into the heating chamber.
[0045] The insertion and removal of cigarettes can be divided into four states: before cigarette insertion, after cigarette insertion, before cigarette removal, and after cigarette removal. Before cigarette insertion, when no cigarette is inserted into the heating chamber, the capacitance value collected by the capacitance sensor at this time is used as the initial capacitance value. In some embodiments, the capacitance value collected by the capacitance sensor before cigarette removal can also be used as the initial capacitance value. Therefore, the initially defined initial capacitance value is the capacitance value collected by the capacitance sensor in a certain insertion / removal state of the cigarette, and it is a fixed value.
[0046] Step S20: Obtain the current capacitance value collected by the capacitance sensor based on the preset frequency, and calculate the capacitance difference between the current capacitance value and the initial capacitance value.
[0047] During the insertion and removal of the cigarette, factors such as the cigarette and ambient temperature cause changes in capacitance. The capacitance difference between the current capacitance and the initial capacitance is used as a characteristic parameter for switching the on / off state of the smoking device.
[0048] Step S30: Based on a preset time period, if the capacitance difference meets the first condition, the initial capacitance value is updated to the current capacitance value and the timing is restarted. If the capacitance difference does not meet the first condition but meets the second condition, the on / off state of the smoking device is switched, the initial capacitance value is updated to the current capacitance value and the timing is restarted. The preset time period is greater than the preset insertion / removal time of the smoking device.
[0049] In one example, the average insertion and removal time obtained from several insertion and removal experiments on the smoking device is used as the preset insertion and removal time.
[0050] In one example, the preset insertion / removal time can be understood as the time it takes for a user to normally insert and remove a cigarette. Therefore, a certain number of users can be selected as a sample, and the insertion / removal time of each user during the use of the same model of smoking device can be recorded. The median of the insertion / removal time in the sample can be selected as the preset insertion / removal time.
[0051] The preset time period is the time condition for updating the initial capacitor value. On the one hand, a preset time period greater than the preset insertion / removal time of the smoking device is a necessary condition for the start and stop control of the smoking device. On the other hand, the size of the preset time period affects the reliability of the start and stop of the smoking device. For example, the preset time period is 2 seconds.
[0052] The first condition is that the capacitance difference is less than or equal to a preset update threshold, and the second condition is that the capacitance difference is within a preset difference range, wherein the preset update threshold is less than the minimum value of the preset difference range.
[0053] In some embodiments, the preset difference range is determined by the maximum and minimum values of the capacitance difference obtained from several insertion and removal experiments on the smoking device.
[0054] Assuming the capacitance value collected by the capacitance sensor before cigarette insertion is an initial capacitance value C0, and the capacitance value collected by the capacitance sensor after cigarette insertion is C1, then the capacitance difference obtained in this insertion and removal experiment is ΔC = C1 - C0. Several insertion and removal experiments are performed on the cigarette device to obtain several capacitance differences ΔC. The maximum value ΔCmax and the minimum value ΔCmin of the capacitance difference ΔC are then recorded. A preset difference range (ΔCmin, ΔCmax) is determined based on the maximum value ΔCmax and the minimum value ΔCmin. The preset difference range (ΔCmin, ΔCmax) represents the range of capacitance value change before and after cigarette insertion.
[0055] Assuming the capacitance value collected by the capacitance sensor before the cigarette is removed is an initial capacitance value C0, and the capacitance value collected by the capacitance sensor after the cigarette is removed is C1, then the capacitance difference obtained in this insertion and removal experiment is ΔC = C1 - C0. Several insertion and removal experiments are performed on the cigarette device to obtain several capacitance differences ΔC. The maximum value ΔCmax and the minimum value ΔCmin of the capacitance difference ΔC are then taken. A preset difference range (ΔCmin, ΔCmax) is determined based on the maximum value ΔCmax and the minimum value ΔCmin. The preset difference range (ΔCmin, ΔCmax) is the range of capacitance value change before and after the cigarette is removed.
[0056] In some embodiments, the preset update threshold is equal to the minimum value of 1 / 2 of the capacitance difference.
[0057] The preset update threshold can be obtained by conducting several insertion and removal experiments on the smoking device. For example, select several values at equal intervals between 0 and the minimum value of the capacitance difference, conduct the same number of insertion and removal experiments for each value, and select the value with the highest accuracy in triggering the start or stop of the smoking device when the cigarette is inserted or removed as the preset update threshold.
[0058] During the insertion and removal of a cigarette, the capacitance value collected by the capacitance sensor will not instantly change to its maximum value, but will exhibit one or more intermediate changes. To ensure the accuracy of switching the on / off state of the cigarette device, a preset update threshold is used as a confidence value. If the capacitance difference between the current and initial capacitance values is greater than the preset update threshold, it means that the capacitance difference between the current and initial capacitance values may have reached its minimum value and may be within the preset difference range, thus potentially meeting the conditions for switching the on / off state of the cigarette device. If the capacitance difference between the current and initial capacitance values is less than or equal to the preset update threshold, it means that the capacitance difference between the current and initial capacitance values cannot have reached its minimum value and cannot be within the preset difference range, thus potentially failing to meet the conditions for switching the on / off state of the cigarette device.
[0059] It is understandable that the preset update threshold can be any value between the minimum value of 1 / 2 of the capacitance difference and the minimum value of the capacitance difference.
[0060] like Figure 3 As shown, step S30 can be achieved through the following steps:
[0061] Step S311: When the preset time period is reached, determine whether the capacitance difference is less than or equal to the preset update threshold.
[0062] Step S312: If yes, update the initial capacitance value to the current capacitance value and restart the timer.
[0063] Since the preset update threshold is less than the minimum value of the preset difference range, if the capacitance difference is less than or equal to the preset update threshold, it means the capacitance difference cannot reach the minimum value and cannot be within the preset difference range, meaning the conditions for switching the smoking device's on / off state cannot be met. Therefore, the initial capacitance value needs to be updated to the current capacitance value to prepare for the next test. If the capacitance difference is greater than the preset update threshold, it means the capacitance difference may reach the minimum value and may be within the preset difference range, meaning the conditions for switching the smoking device's on / off state may be met. Therefore, it is necessary to continue to determine whether the capacitance difference is within the preset difference range. In this case, if the initial capacitance value is updated to the current capacitance value, making the capacitance difference between the current and initial capacitance values smaller, it may cause the smoking device to fail to start or stop when the cigarette is plugged in or unplugged.
[0064] As mentioned earlier, during the insertion and removal of cigarettes, factors such as the cigarette and ambient temperature cause changes in capacitance. Therefore, it is necessary to update the initial capacitance value based on a preset time period to filter out changes in capacitance caused by factors such as ambient temperature. By using the capacitance difference between the current capacitance value and the initial capacitance value during the insertion and removal of cigarettes as a characteristic parameter for switching the on / off state of the smoking device, the control accuracy of starting and stopping the smoking device can be effectively improved.
[0065] The timing is reset to wait for the next preset time period to arrive. If the timing is not reset after the initial capacitance value is updated, the initial capacitance value will be updated continuously, and the capacitance difference will always be equal to 0, making all judgment steps related to the capacitance difference meaningless.
[0066] Step S313: If not, determine whether the capacitance difference is within the preset difference range.
[0067] Step S314: If yes, switch the on / off state of the smoking device, update the initial capacitance value to the current capacitance value, and restart the timer.
[0068] Step S30 further includes: if not, returning to the step of obtaining the current capacitance value collected by the capacitance sensor based on a preset frequency.
[0069] The switching of the smoking device's on / off state includes: if the smoking device is in the on state, controlling the smoking device to switch to the off state; if the smoking device is in the off state, controlling the smoking device to switch to the on state.
[0070] It's understandable that switching the on / off state of the smoking device is equivalent to the device changing from one state to another, which is considered a change in the external environment, requiring an update of the initial capacitance value.
[0071] Step S40: Return to the step of obtaining the current capacitance value collected by the capacitance sensor based on the preset frequency.
[0072] After updating the initial capacitance value to the current capacitance value and resetting the timer, the system returns to the current capacitance value acquired by the capacitance sensor based on a preset frequency, and continues to prepare for the next detection.
[0073] like Figure 4 As shown, before obtaining the initial capacitance value and triggering the timing, the method also includes: power-on initialization.
[0074] The smoking device control method provided in this application obtains the initial capacitance value collected by the capacitance sensor when no cigarette is inserted into the heating chamber and triggers timing. Based on a preset frequency, it obtains the current capacitance value collected by the capacitance sensor and calculates the capacitance difference between the current capacitance value and the initial capacitance value. Based on a preset time period, if the capacitance difference meets a first condition, the initial capacitance value is updated to the current capacitance value and timing is restarted. If the capacitance difference does not meet the first condition but meets a second condition, the on / off state of the smoking device is switched, the initial capacitance value is updated to the current capacitance value and timing is restarted. This allows the method to adapt to changes in capacitance value due to changes in ambient temperature, avoids the influence of ambient temperature on the start and stop of the smoking device, and improves the control accuracy of the start and stop of the smoking device.
