一种可校准启动阈值的电子烟An electronic cigarette with a calibrated activation threshold

技术领域technical field

本申请实施例涉及电子烟技术领域,尤其涉及一种可校准启动阈值的电子烟。The embodiments of the present application relate to the technical field of electronic cigarettes, and in particular, to an electronic cigarette with a calibratable activation threshold.

背景技术Background technique

现有的电子烟咪头多是采用单电容形式的传感器,检测使用者是否有抽吸动作。其中,极片和膜片形成单电容传感器,单电容传感器与传感器控制芯片IC相连。当无抽吸时,膜片几乎不发生形变,因此与极片形成的电容值不发生变化,传感器控制芯片不发出吸烟信号,电子烟不工作;当抽吸时(负压的状态),膜片由于负压发生形变,使得膜片与极片之间的距离发生变化,导致两者形成的电容值发生改变,传感器控制芯片侦测电容的变化量达到设定的电容阈值,则传感器控制芯片输出点烟信号,使电子烟工作,产生烟雾。Most of the existing electronic cigarette microphone heads use sensors in the form of single capacitors to detect whether the user has a smoking action. Among them, the pole piece and the diaphragm form a single capacitance sensor, and the single capacitance sensor is connected with the sensor control chip IC. When there is no smoking, the diaphragm hardly deforms, so the capacitance value formed with the pole piece does not change, the sensor control chip does not send a smoking signal, and the electronic cigarette does not work; when smoking (negative pressure state), the film Due to the deformation of the negative pressure, the distance between the diaphragm and the pole piece changes, resulting in a change in the capacitance value formed by the two, and the sensor control chip detects that the change in capacitance reaches the set capacitance threshold, then the sensor control chip Output the cigarette light signal, make the electronic cigarette work, and generate smoke.

现有的电容式传感器,最主要的参数是极片与膜片之间形成的平行板电容(也可以简称电容)。电容的变化量容易受一些因素影响,例如膜片的张紧力、极片与膜片之间的垫片的公差等;同时,在电容式传感器组装工序上,由于外部封口压力的差异,也可能导致电容式传感器的膜片与极片之间最终形成的电容值并不一致,进而影响电容的变化量。另外,电子烟在组装过程中,由于结构压力的公差、结构尺寸的公差、气道的差异等影响,可能导致组装完成的电子烟存在公差,从而也影响电容的变化量。可见,由于上述一些影响因素的存在,可能使得多个电子烟在相同的负压环境下反而电容变化量不一致。In the existing capacitive sensor, the most important parameter is the parallel plate capacitance (also referred to as capacitance) formed between the pole piece and the diaphragm. The change in capacitance is easily affected by some factors, such as the tension of the diaphragm, the tolerance of the gasket between the pole piece and the diaphragm, etc. At the same time, in the assembly process of the capacitive sensor, due to the difference in the external sealing pressure, It may cause that the final capacitance value formed between the diaphragm and the pole piece of the capacitive sensor is inconsistent, which in turn affects the amount of capacitance change. In addition, during the assembly process of the electronic cigarette, due to the influence of structural pressure tolerance, structural size tolerance, airway difference, etc., the assembled electronic cigarette may have tolerances, which also affects the amount of capacitance change. It can be seen that due to the existence of some of the above-mentioned influencing factors, the capacitance changes of multiple electronic cigarettes may be inconsistent under the same negative pressure environment.

由于电容变化量与电容阈值之间的大小关系决定着电子烟是否触发点烟操作,如果设置有相同电容阈值的电子烟,在相同的负压环境下的电容变化量不一致,则可能出现有的电子烟触发点烟操作,有的电子烟未触发点烟操作的情况。Since the relationship between the capacitance change and the capacitance threshold determines whether the electronic cigarette triggers the cigarette lighting operation, if the electronic cigarettes with the same capacitance threshold have different capacitance changes under the same negative pressure environment, there may be some The electronic cigarette triggers the cigarette lighting operation, and some electronic cigarettes do not trigger the cigarette lighting operation.

下面将结合图1对本申请实施例公开的电子烟进行示例说明。The electronic cigarette disclosed in the embodiment of the present application will be illustrated below with reference to FIG. 1 .

电子烟正常工作时,当电子烟外部环境出现负压,例如消费者进行抽烟的动作,电容传感器内部工作状态如下:膜片102会往极片101方向形变,由膜片102与极片101形成的类似平极板电容电容值会变大,传感器控制芯片实时检测该电容值的变化量。若该电容值的变化量超过传感器控制芯片设定的电容预设值(可称为电容阈值)C_offset,传感器控制芯片输出触发吸烟信号,给电子烟的主控芯片,主控芯片通过控制功率输出电路,,让雾化组件产生烟雾。When the electronic cigarette is working normally, when there is negative pressure in the external environment of the electronic cigarette, for example, the consumer is smoking, the internal working state of the capacitive sensor is as follows: thediaphragm 102 will deform in the direction of thepole piece 101, which is formed by thediaphragm 102 and thepole piece 101. The capacitance value of the similar flat plate capacitance will become larger, and the sensor control chip detects the change of the capacitance value in real time. If the change of the capacitance value exceeds the capacitance preset value (which can be called the capacitance threshold) C_offset set by the sensor control chip, the sensor control chip outputs a triggering smoking signal to the main control chip of the electronic cigarette, and the main control chip controls the power output by The circuit, which allows the atomizing component to generate smoke.

上面对于电子烟的工作流程做了说明,基于前述说明的工作过程,可以理解到,电子烟在外部负压环境中,当传感器控制芯片检测到的电容变化量超过传感器控制芯片中的电容阈值,电子烟才能触发吸烟。而电子烟中的传感器控制芯片的电容阈值一般是固定的,如果设置有相同电容阈值的电子烟,在相同的负压环境下的电容变化量不一致,则可能出现有的电子烟触发点烟操作,有的电子烟未触发点烟操作的情况。因此,本申请实施例提供了一种可以自动校准传感器控制芯片的电容阈值的电子烟。下面对校准电子烟进行了详细描述。The working process of the electronic cigarette is explained above. Based on the working process described above, it can be understood that when the electronic cigarette is in an external negative pressure environment, when the capacitance change detected by the sensor control chip exceeds the capacitance threshold in the sensor control chip, E-cigarettes can trigger smoking. The capacitance threshold of the sensor control chip in the electronic cigarette is generally fixed. If the electronic cigarettes with the same capacitance threshold are set, the capacitance changes in the same negative pressure environment are inconsistent, and some electronic cigarettes may trigger the cigarette lighting operation. , Some electronic cigarettes do not trigger the cigarette lighting operation. Therefore, the embodiments of the present application provide an electronic cigarette that can automatically calibrate the capacitance threshold of the sensor control chip. Calibrating e-cigarettes is described in detail below.

请参阅图2,电子烟在进行校准时,主要应用到电子烟内部的电容式传感器201、主控芯片203和传感器控制芯片202。Please refer to FIG. 2 , when the electronic cigarette is calibrated, it is mainly applied to thecapacitive sensor 201 , themain control chip 203 and thesensor control chip 202 inside the electronic cigarette.

其中:电容式传感器201,与传感器控制芯片202相连,用于在电子烟外部不存在负压环境时产生第一电容值,以及基于电子烟外部施加的负压校准环境产生第二电容值,传感器控制芯片202可以检测得到该第一电容值和该第二电容值。可以理解得是,电子烟外部不存在负压环境可以指,电子烟在组装完成后,电子烟的烟嘴处没有产生负压的动作,该动作可以是抽吸电子烟的烟嘴。而负压校准环境,指的是一个特定的负压,电容式传感器根据该负压可产生一个特定的电容值,该负压校准环境一般由特定的作业设备提供,可以是-150pa、-200pa或者-300pa,具体此处不做限定。Thecapacitive sensor 201 is connected to thesensor control chip 202, and is used to generate a first capacitance value when there is no negative pressure environment outside the electronic cigarette, and generate a second capacitance value based on the negative pressure calibration environment applied outside the electronic cigarette. Thecontrol chip 202 can detect the first capacitance value and the second capacitance value. It can be understood that the absence of a negative pressure environment outside the electronic cigarette means that after the electronic cigarette is assembled, there is no action of generating negative pressure at the mouthpiece of the electronic cigarette, and the action can be the mouthpiece for smoking the electronic cigarette. The negative pressure calibration environment refers to a specific negative pressure, and the capacitive sensor can generate a specific capacitance value according to the negative pressure. The negative pressure calibration environment is generally provided by specific operating equipment, which can be -150pa, -200pa Or -300pa, there is no specific limitation here.

主控芯片203,与传感器控制芯片202相连,在接收到校准指令时产生校准信号,并将该校准信号发送给传感器控制芯片203。在一种具体的实施方式中,该校准指令可以通过外部连接附件进行触发,该外部连接附件与主控芯片203相连,可向主控芯片203传输指令。而该校准信号可以是高电平信号或脉冲信号,具体此处不做限定,该校准信号可以被传感器控制芯片202识别。Themain control chip 203 is connected to thesensor control chip 202 , generates a calibration signal when receiving a calibration instruction, and sends the calibration signal to thesensor control chip 203 . In a specific implementation manner, the calibration instruction can be triggered by an external connection accessory, and the external connection accessory is connected to themain control chip 203 and can transmit an instruction to themain control chip 203 . The calibration signal may be a high-level signal or a pulse signal, which is not specifically limited here, and the calibration signal may be recognized by thesensor control chip 202 .

传感器控制芯片202,接收到主控芯片203发送的校准信号后,进入校准模式。传感器控制芯片202检测电容式传感器201上产生的第一电容值和第二电容值,将第一电容值和第二电容值进行对比,得到电容变化量(简称第一电容差)C_new,判断该第一电容差是否在有效范围内。如果该第一电容差在有效范围内,则将该第一电容差作为目标电容阈值。可以理解的是,将该第一电容差作为目标电容阈值可以有多种实现方式,例如一种实现方式为,原本传感器控制芯片202中无预设电容阈值,直接将该第一电容差作为目标阈值;另一种实现方式,将该第一电容差替代传感器控制芯片上原本的预设电容阈值。在这里,该目标电容阈值指的是,传感器控制芯片202中的触发吸烟信号的负压启动阈值;该预设电容阈值指的是,电子烟在整机组装前,传感器控制芯片202检测未组装入该电子烟的电容传感器201产生得到的电容阈值。在一种具体实施方式中,当传感器控制芯片202将该第一电容差作为目标电容阈值后,还可以进一步向主控芯片203发送校准成功信号,传感器控制芯片202校准完成退出校准模式。Thesensor control chip 202 enters the calibration mode after receiving the calibration signal sent by themain control chip 203 . Thesensor control chip 202 detects the first capacitance value and the second capacitance value generated on thecapacitive sensor 201, compares the first capacitance value and the second capacitance value, and obtains the capacitance change amount (referred to as the first capacitance difference) C_new, and judges the Whether the first capacitance difference is within the valid range. If the first capacitance difference is within the valid range, the first capacitance difference is used as the target capacitance threshold. It can be understood that there can be various implementations to use the first capacitance difference as the target capacitance threshold. For example, one implementation is that there is no preset capacitance threshold in thesensor control chip 202, and the first capacitance difference is directly used as the target. threshold; in another implementation manner, the first capacitance difference replaces the original preset capacitance threshold on the sensor control chip. Here, the target capacitance threshold refers to the negative pressure start threshold in thesensor control chip 202 that triggers the smoking signal; the preset capacitance threshold refers to thesensor control chip 202 detecting that the electronic cigarette is not assembled before the whole electronic cigarette is assembled Thecapacitance sensor 201 of the electronic cigarette generates the obtained capacitance threshold. In a specific embodiment, after thesensor control chip 202 uses the first capacitance difference as the target capacitance threshold, it can further send a calibration success signal to themain control chip 203, and thesensor control chip 202 exits the calibration mode after the calibration is completed.

本申请实施例的电子烟包括传感器控制芯片、主控芯片和电容式传感器,传感器控制芯片接收到主控芯片发送的校准信号后,通过检测电容式传感器上的电容值,得到与负压校准环境对应的第一电容差,将该第一电容差作为传感器控制芯片上的电容阈值。当电子烟外部被施加与负压校准环境相同的负压环境时,传感器控制芯片上得到的第二电容差与第一电容差相等,且该第二电容差能达到电容阈值,使电子烟触发吸烟。通过本申请实施例,电子烟还可以在存在公差时,能够调整传感器控制芯片上的电容阈值,使电子烟触发吸烟信号,减少了公差的影响,提高了生产良率,还可以尽可能保证传感器控制芯片触发吸烟信号时外部负压环境相同;并且在不同的负压环境时,通过调整阈值,使不同的负压环境也能触发吸烟,提高了触发吸烟的灵敏度。The electronic cigarette of the embodiment of the present application includes a sensor control chip, a main control chip, and a capacitive sensor. After the sensor control chip receives the calibration signal sent by the main control chip, it detects the capacitance value on the capacitive sensor to obtain a negative pressure calibration environment. The corresponding first capacitance difference is used as the capacitance threshold on the sensor control chip. When the same negative pressure environment as the negative pressure calibration environment is applied to the outside of the electronic cigarette, the second capacitance difference obtained on the sensor control chip is equal to the first capacitance difference, and the second capacitance difference can reach the capacitance threshold, so that the electronic cigarette triggers smoking. Through the embodiments of the present application, the electronic cigarette can also adjust the capacitance threshold on the sensor control chip when there is a tolerance, so that the electronic cigarette can trigger the smoking signal, reduce the influence of the tolerance, improve the production yield, and ensure the sensor as much as possible. When the control chip triggers the smoking signal, the external negative pressure environment is the same; and in different negative pressure environments, by adjusting the threshold, different negative pressure environments can also trigger smoking, which improves the sensitivity of triggering smoking.

In the embodiment of this application, the electronic cigarette can be calibrated multiple times in different negative pressure environments, and the negative pressure environment can be -200pa or -400pa, which is not limited here, and the effective range of each calibration is fixed. That is, the preset capacitance threshold on thesensor control chip 202 is fixed, but the first capacitance difference can vary.

If the capacitance difference is not within the valid range, thesensor control chip 202 sends a calibration failure signal to themain control chip 203 and exits the calibration mode. After receiving the calibration failure signal, themain control chip 203 outputs a prompt message indicating that the electronic cigarette is an unqualified product. have to be aware of is,

当传感器控制芯片202校准完成后,传感器控制芯片202实时检测电容式传感器201上产生的第三电容值,该第三电容值是在电子烟外部施加负压环境时产生的,可表示该电子烟外部存在抽吸动作时产生的。传感器控制芯片202将该第三电容值和第一电容值对比,获得第二电容差,如果该第二电容差大于目标电容值,即该第二电容差大于第一电容差,传感器控制芯片202向主控芯片203发送触发吸烟信号。主控芯片203接收到该触发吸烟信号后,会向电子烟中的雾化组件204发送点烟信号;雾化组件204响应于该点烟信号,在电子烟的烟嘴处产生烟雾。After the calibration of thesensor control chip 202 is completed, thesensor control chip 202 detects the third capacitance value generated on thecapacitive sensor 201 in real time. The third capacitance value is generated when a negative pressure environment is applied outside the electronic cigarette, which can indicate that the electronic cigarette Generated when there is a suction action externally. Thesensor control chip 202 compares the third capacitance value with the first capacitance value to obtain a second capacitance difference. If the second capacitance difference is greater than the target capacitance value, that is, the second capacitance difference is greater than the first capacitance difference, thesensor control chip 202 Send a smoking trigger signal to themain control chip 203 . After receiving the smoking trigger signal, themain control chip 203 will send a cigarette lighting signal to theatomizing component 204 in the electronic cigarette; theatomizing component 204 generates smoke at the mouthpiece of the electronic cigarette in response to the cigarette lighting signal.

上面对校准电子烟进行了详细描述,下面对于校准电子烟的一种应用方式进行了说明。请参阅图4,本申请实施例中的一种可能实现方案中,当负压环境施加在电子烟吸嘴端进行模拟消费者的吸烟状态,此时,电子烟内部气流由气孔1,气孔2,气孔3方向,流向吸嘴端。预设电容阈值相同的电子烟也会存在差异,电子烟的外部负压环境可以通过设备调节固定在一个固定的负压值;但是外部负压环境相同时,电子烟中电容式传感器产生的负压值可能并不相同,传感器控制芯片检测到的电容差达不到预设的电容阈值。为了使多个电子烟在相同的外部负压环境时,传感器控制芯片产生触发吸烟信号,可以对多个电子烟在相同的外部负压环境下校准负压启动阈值,使多个电子烟可以触发吸烟。这样可以尽可能保证多个电子烟在相同的外部负压环境下触发吸烟,从而保证批量出货的一致性。The calibration of the electronic cigarette is described in detail above, and an application manner of calibrating the electronic cigarette is described below. Please refer to FIG. 4 , in a possible implementation solution in the embodiment of the present application, when a negative pressure environment is applied to the mouth end of the electronic cigarette to simulate the smoking state of the consumer, at this time, the air flow inside the electronic cigarette is composed of air holes 1 and 2. , the direction of the air hole 3, flows to the nozzle end. Electronic cigarettes with the same preset capacitance threshold will also have differences. The external negative pressure environment of the electronic cigarette can be adjusted and fixed at a fixed negative pressure value through the device; however, when the external negative pressure environment is the same, the negative pressure generated by the capacitive sensor in the electronic cigarette The voltage values may not be the same, and the difference in capacitance detected by the sensor control chip cannot reach the preset capacitance threshold. In order to make multiple electronic cigarettes in the same external negative pressure environment, the sensor control chip generates a triggering signal for smoking, and the negative pressure start threshold can be calibrated for multiple electronic cigarettes in the same external negative pressure environment, so that multiple electronic cigarettes can be triggered smoking. This can ensure that multiple electronic cigarettes trigger smoking in the same external negative pressure environment as much as possible, thereby ensuring the consistency of batch shipments.
