Apparently, the described embodiments are merely some rather than all of the embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the disclosure without creative efforts shall fall within the scope of the disclosure.

Referring to <FIG>, an electronic atomizing device <NUM> is configured to heat and atomize an aerosol-generation product <NUM>. For example, a solid substrate of plant leaves with a specific aroma can generate an aerosol that has an obvious aroma and can satisfy users more effectively in a heating condition. The electronic atomizing device <NUM> bakes the solid substrate of plant leaves with a specific aroma in a heat-not-burning manner so that the solid substrate of plant leaves is baked into an aerosol. The electronic atomizing device <NUM> in the disclosure is applicable to different fields, such as a medical treatment, a beauty treatment, or a recreational smoking.

In an embodiment, the electronic atomizing device <NUM> is fixedly or detachably connected to the aerosol-generation product <NUM> to provide heating energy for the aerosol-generation product <NUM>, so as to heat and atomize an aerosol stored in the aerosol-generation product <NUM> to generate a substrate.

The inventors of the disclosure found that a single traditional aerosol-generation product <NUM> is usually packaged in a packaging box before used or the plurality of traditional aerosol-generation products <NUM> are usually packaged in a packaging box before used. After the packaging box of the aerosol-generation product <NUM> is opened, the aerosol-generation substrate in the packaging box absorbs moisture in the air. Therefore, a later used aerosol-generation product <NUM> includes more moisture. For example, for the single aerosol-generation product <NUM> packaged in a packaging box, a longer waiting time since opened of the packaging box to used leads to more moisture in the aerosol-generation product <NUM>, or a longer waiting time since current suction to next suction leads to more moisture in the aerosol-generation product <NUM>. For the plurality of aerosol-generation products <NUM> packaged in a packaging box, in the opened packaging box, a volume of moisture of an aerosol-generation product <NUM> used later is more than a volume of moisture of an aerosol-generation products <NUM> used earlier. Alternatively, the aerosol-generation product <NUM> includes other liquids caused by an misoperation of a user. As a result, the aerosol-generation product <NUM> cannot be heated and atomized by the electronic atomizing device to a preset temperature, resulting in a reduced volume of atomized aerosols generated in the aerosol-generation product <NUM>, and affecting user experience.

Therefore, the disclosure provides an electronic atomizing device <NUM>. Referring to <FIG>, the electronic atomizing device <NUM> includes a heating unit <NUM>, a power supply unit <NUM>, and a control unit <NUM>. The aerosol-generation product <NUM> is accommodated in the heating unit <NUM>, and the power supply unit <NUM> is configured to provide heating energy for the heating unit <NUM>, so that the heating unit <NUM> heats and atomizes the aerosol-generation product <NUM>. The control unit <NUM> is configured to obtain the liquid content of the aerosol-generation product <NUM> in the heating unit <NUM> and control, according to the obtained liquid content of the aerosol-generation product <NUM>, a power outputted by the power supply unit <NUM> to the heating unit <NUM>, to heat the aerosol-generation product <NUM>.

In an embodiment, the control unit <NUM> further includes a sampling unit <NUM>. The sampling unit <NUM> is configured to detect electrical parameters of the heating unit <NUM> and the aerosol-generation product <NUM>, and the control unit <NUM> further obtains the liquid content of the aerosol-generation product <NUM> according to the electrical parameters detected by the sampling unit <NUM>.

Referring to <FIG>, the electronic atomizing device <NUM> further includes a first conductor <NUM> and a second conductor <NUM>. The first conductor <NUM> and the second conductor <NUM> are electrically connected to the sampling unit <NUM> respectively. When the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>, the first conductor <NUM> and the second conductor <NUM> come into contact with the aerosol-generation product <NUM> and are used as electrodes for the sampling unit <NUM> to collect electrical parameters on two ends of the aerosol-generation product <NUM>. In an embodiment, the first conductor <NUM> is configured to accommodate the aerosol-generation product <NUM>, and the second conductor <NUM> is spaced apart from the first conductor <NUM>. When the aerosol-generation product <NUM> is not inserted into the electronic atomizing device <NUM>, the first conductor <NUM> and the second conductor <NUM> are insulated from each other. The aerosol-generation product <NUM> is conductive. When the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>, the aerosol-generation product is electrically connected to the first conductor <NUM> and the second conductor <NUM> respectively, so that the first conductor <NUM> and the second conductor <NUM> are electrically connected by the aerosol-generation product <NUM>.

The sampling unit <NUM> is configured to: apply a voltage between the first conductor <NUM> and the second conductor <NUM>, collect an initial electrical parameter between the first conductor <NUM> and the second conductor <NUM> when the first conductor <NUM> and the second conductor <NUM> are not electrically connected by the aerosol-generation product <NUM>, and collect an electrical parameter between the first conductor <NUM> and the second conductor <NUM> when the first conductor <NUM> and the second conductor <NUM> are electrically connected by the aerosol-generation product <NUM>.

The electrical parameter is a capacitance value and/or a resistance value between the first conductor <NUM> and the second conductor <NUM>.

The control unit <NUM> is configured to: obtain the liquid content of the aerosol-generation product <NUM> according to the electrical parameter detected by the sampling unit <NUM>, and control, according to the liquid content of the aerosol-generation product <NUM>, the heating element to heat the aerosol-generation product <NUM>.

In an embodiment, the first conductor <NUM> is a hollow columnar structure, such as a cylinder, and is connected to the sampling unit <NUM>. The second conductor <NUM> may be plate-shaped or block-shaped, and is connected to the sampling unit <NUM> as a detection base. Materials of the first conductor <NUM> and the second conductor <NUM> may be metal, such as stainless steel. In an embodiment, the material of the first conductor <NUM> is metal, and the first conductor is configured to generate heat by induction in a magnetic field. The material of the second conductor <NUM> is conductive carbon or conductive ceramics, and configured to prevent the second conductor <NUM> from generating heat by induction in the magnetic field and thereby avoiding causing uneven heating of the aerosol-generation product <NUM>.

When the aerosol-generation product <NUM> is not inserted into the electronic atomizing device <NUM>, an electrical signal loop cannot be formed between the first conductor <NUM> and the second conductor <NUM> since the first conductor <NUM> and the second conductor <NUM> are spaced apart. In this case, the sampling unit <NUM> denotes an electrical parameter between the first conductor <NUM> and the second conductor <NUM> as the initial electrical parameter. When the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>, the aerosol-generation product <NUM> is in sufficiently contact with the first conductor <NUM>, and electrically connects the first conductor <NUM> to the second conductor <NUM>, which changes the capacitance value and the resistance value between the first conductor <NUM> and the second conductor <NUM>. The sampling unit <NUM> collects the electrical parameter between the first conductor <NUM> and the second conductor <NUM> again. The control unit <NUM> compares the initial electrical parameter collected by the sampling unit <NUM> with the electrical parameter after the first conductor <NUM> and the second conductor <NUM> are electrically connected, obtains a first difference between the two electrical parameters by algorithm filtering, compares the first difference with a preset threshold to obtain a second difference, and obtains the liquid content of the aerosol-generation product <NUM>, according to the second difference, by table look-up or calculation. The liquid content of the aerosol-generation product <NUM> looked up, according to the second difference, by the table look-up and the preset threshold are obtained by testing in experiments, and are pre-stored in the control unit <NUM>.

The first conductor <NUM> and the second conductor <NUM> are equivalent to a transceiver for capacitance sensing and resistance measurement, which receives and sends a capacitance sensing signal and a resistance change signal.

In an embodiment, the heating unit <NUM> further includes an insulator <NUM> arranged between the first conductor <NUM> and the second conductor <NUM> for spacing the first conductor <NUM> apart from the second conductor <NUM>. The insulator <NUM> has a through hole, and the aerosol-generation product <NUM> can pass through the first conductor <NUM> and the insulator <NUM> and is electrically connected to the second conductor <NUM>. In an embodiment, the insulator <NUM> is an annular body. The first conductor <NUM> is arranged on a top of the insulator <NUM> and is arranged coaxially with the insulator <NUM>, and the second conductor <NUM> is arranged on the bottom of the insulator <NUM> and covers the bottom of the insulator <NUM>. The second conductor <NUM> also has an air inlet hole (not shown) in communication with inside of the insulator <NUM>.

In a specific embodiment, the insulator <NUM> is an annular body with a flange on the inner wall. The upper surface of the flange abuts against the bottom of the first conductor <NUM>, and the outer sidewall of the first conductor <NUM> abuts against the inner sidewall of the insulator <NUM>. The second conductor <NUM> is arranged on the lower surface of the flange and covers the bottom of the insulator <NUM>. The first conductor <NUM>, the second conductor <NUM>, and the insulator <NUM> may be in interference fit or may be bonded, so as to simplify an assembly process of the electronic atomizing device <NUM>.

In an embodiment, the heating unit <NUM> performs electromagnetic heating. Specifically, the first conductor <NUM> is further used as a heating element, and the heating unit <NUM> further includes an electromagnetic coil, and the electromagnetic coil surrounds the first conductor <NUM>. Therefore, when electrified, the first conductor <NUM> generates heat by electromagnetic induction to heat and atomize the aerosol-generation product <NUM>.

In another embodiment, the heating unit <NUM> performs resistive heating, and the heating unit <NUM> is a heating element arranged independently. The heating element may be a centrally needle-shaped heating element or centrally sheet-shaped heating element. The heating element is arranged on the second conductor <NUM> configured to be inserted into the aerosol-generation product <NUM> to heat and atomize the aerosol-generation product <NUM>.

In an embodiment, the electronic atomizing device <NUM> further includes a detection unit (not shown) for detecting whether the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>. When it is detected that the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>, the sampling unit <NUM> and the control unit <NUM> collect and obtain the liquid content of the aerosol-generation product <NUM>. In some optional embodiments, the sampling unit <NUM> may be used as a detection unit. For example, the sampling unit <NUM> constantly applies a voltage between the first conductor <NUM> and the second conductor <NUM> to collect, at any time, the initial electrical parameter and the electrical parameter after the first conductor <NUM> and the second conductor <NUM> are electrically connected, and sends the two electrical parameters to the control unit <NUM> for calculation to obtain the liquid content of the aerosol-generation product <NUM>. When it is detected that the electrical insulation between the first conductor <NUM> and the second conductor <NUM> changes to electrical connection, it is determined that the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>. In this way, it can be ensured that detection of the liquid content is started each time the aerosol-generation product <NUM> is replaced with a new one. In another optional embodiment, the detection unit may be an optical sensor arranged on the inner sidewall of the insulator <NUM> to detect, by optical sensing, whether the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>. Alternatively, the detection unit may be a pressure sensor arranged on the second conductor <NUM> to detect, by pressure sensing, whether the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>. The sampling unit <NUM> may start to apply a voltage between the first conductor <NUM> and the second conductor <NUM> when the detection unit detects that the aerosol-generation product <NUM> is inserted into the electronic atomizing device <NUM>, collect the electrical parameter after the first conductor <NUM> and the second conductor <NUM> are electrically connected, and send the collected electrical parameter to the control unit <NUM>. The control unit <NUM> compares the pre-stored initial electrical parameter with the electrical parameter after the first conductor <NUM> and the second conductor <NUM> are electrically connected, so as to obtain the liquid content of the aerosol-generation product <NUM>. A specific implementation may be selected according to actual requirements, which is not limited herein.

An aerosol-generation product <NUM> that is not pulled out of the electronic atomizing device <NUM> and has been used for a long time absorbs moisture over a long time interval of inhaling. Therefore, in the disclosure, the detection unit is further configured to determine a time interval from a last inhale signal after detecting an inhale signal of a user. When the time interval exceeds a preset time threshold, the sampling unit <NUM> and the control unit <NUM> collect and obtain the liquid content of the aerosol-generation product <NUM> again. The preset time threshold may be <NUM> hours, <NUM> hours, or <NUM> hours, which is selected according to a situation. When the local climate is humid, the preset time threshold may be properly reduced. When the local climate is dry, the preset time threshold may be properly increased.

A method of the control unit <NUM> controlling, according to the liquid content of the aerosol-generation product <NUM>, the heating unit <NUM> to heat the aerosol-generation product <NUM> may be achieve through obtaining relevant data in advance in experiments and pre-stored in the control unit <NUM>. Specifically, in normal cases, a time of the electronic atomizing device <NUM> preheating the aerosol-generation product <NUM> is generally <NUM>-<NUM> seconds, and a preheating temperature is <NUM>-<NUM> Celsius degrees. A total power for preheating an aerosol-generation product <NUM> that is just opened, i.e., a total power for preheating an aerosol-generation product <NUM> that does not absorb moisture may be calculated according to a heating voltage and a heating resistance.

Referring to Table <NUM>, it may be learned that the heating element is equivalent to a thermistor, an initial resistance of the heating element is <NUM>Ω, and an actual resistance of the heating element varies with a heating temperature.

Since the aerosol-generation product <NUM> absorbs moisture after opened, the weight of a single aerosol-generation product <NUM> increases. Heat and power consumption for additional water evaporation may be calculated according to a specific heat capacity of water and heat absorbed by water evaporation.

As shown in Table <NUM>, a boiling point of water is <NUM> Celsius degrees. Therefore, after the aerosol-generation product <NUM> that absorbed moisture is preheated to <NUM> Celsius degrees, the liquid content of the aerosol-generation product <NUM> approximates <NUM>. After continuous heating, heat and power consumption for the liquid evaporation are substantially <NUM>.

Referring to <FIG> and <FIG>, after the aerosol-generation product <NUM> is inserted into the first conductor <NUM>, the sampling unit <NUM> detects an electrical parameter of the aerosol-generation product <NUM>. A dielectric constant of an aerosol-generation product <NUM> after one day since opened (shown in <FIG>) and a dielectric constant of an aerosol-generation product that is just opened (shown in <FIG>) are significantly different, which indicates that the liquid contents are significantly different. Specifically, as shown by a line B in the figure, before the aerosol-generation product is inserted into the first conductor <NUM>, the control unit <NUM> constantly calibrates current potential data as reference potential data. As shown by a line A in the figure, after the aerosol-generation product is inserted into the first conductor <NUM>, the potential data changes. The control unit determines the liquid content in the aerosol-generation product <NUM> by determining the change of the line A relative to the line B, and determines, by experiments, an amount of heat to be compensated or a heating curve to be used for the aerosol-generation product <NUM> with a different liquid content. The control unit <NUM> pre-stores the relevant experiment parameter, obtains the liquid content of the aerosol-generation product <NUM> according to the relevant electrical parameter detected by the sampling unit <NUM>, and controls, according to the liquid content, the heating element to heat the aerosol-generation product <NUM>.

Specifically, the control unit <NUM> obtains the liquid content of the aerosol-generation product <NUM> by calculation and comparison. In an embodiment, the control unit <NUM> includes a microcontroller unit (MCU) <NUM>. The MCU receives the electrical parameters fed back by the sampling unit <NUM>, determines the liquid content of the aerosol-generation product <NUM>, obtains a preset heating curve matching the liquid content of the aerosol-generation product <NUM> based on the liquid content of the aerosol-generation product <NUM>, and controls the heating element to heat the aerosol-generation product <NUM>.

In an embodiment, referring to <FIG>, a preset heating curve set corresponding to different liquid contents in the aerosol-generation product <NUM> are pre-stored in the control unit <NUM>. The control unit <NUM> selects a preset heating curve matching the liquid content of a current aerosol-generation product <NUM> from the pre-stored preset heating curve set. Each of a preheating time and/or a preheating temperature in a preset heating curve in the preset heating curve set for preheating the aerosol-generation product <NUM> varies from that in a different preset heating curve in the preset heating curve set.

For example, when the liquid content of the aerosol-generation product <NUM> is <NUM> or lower than a threshold, the preheating time for the aerosol-generation product <NUM> by the electronic atomizing device <NUM> is <NUM> seconds, the preheating temperature is <NUM> Celsius degrees, and the control unit <NUM> outputs a standard heating curve. When the liquid content of the aerosol-generation product <NUM> is higher than the threshold, the control unit <NUM> outputs a heating curve that has a longer preheating time such as <NUM> seconds or <NUM> seconds for the aerosol-generation product <NUM> than the standard heating curve, or the control unit <NUM> outputs a heating curve that has a higher preheating temperature such as <NUM> Celsius degrees or <NUM> Celsius degrees for the aerosol-generation product <NUM> than the standard heating curve. Alternatively, the preheating temperature and the preheating time for the aerosol-generation product <NUM> both may be increased by a mixture manner, so that the aerosol-generation product <NUM> can be preheated to a target temperature. In one embodiment, a plurality of threshold intervals may be set, and different heating curves are pre-stored in the different threshold intervals. A corresponding heating curve is selected according to a threshold interval corresponding to the liquid content of the aerosol-generation product <NUM>.

Alternatively, the standard heating curve may be a heating curve when the liquid content of the aerosol-generation product <NUM> is a certain value, such as a heating curve in a saturated liquid state. When the liquid content of the aerosol-generation product <NUM> is lower than the saturation value, the control unit <NUM> may output a heating curve that has a shorter preheating time or a lower preheating temperature for the aerosol-generation product <NUM> than the standard heating curve. The standard heating curve is not limited herein.

In another embodiment, the control unit <NUM> may compensate for the pre-stored preset heating curve according to the liquid content of the aerosol-generation product <NUM>, so as to change the preheating time and/or the preheating temperature in the preset heating curve for preheating the aerosol-generation product <NUM>. For example, a preset heating curve is stored in the control unit <NUM>, and the preset heating curve corresponds to a certain value of the liquid content of the aerosol-generation product <NUM>. After obtaining the liquid content of the aerosol-generation product <NUM>, the control unit <NUM> performs logical calculation on the preset heating curve to obtain and output a compensated heating curve, so as to increase or reduce the preheating time or the preheating temperature for the aerosol-generation product <NUM>, so that the aerosol-generation product <NUM> can be heated to a preset temperature. Specifically, the control unit <NUM> compensates for the preset heating curve before outputting the heating curve. It may be understood that, in this method, a correspondence table or a relationship expression between the liquid content of the aerosol-generation product <NUM> and a compensation value is required to be pre-stored, and compensation is performed according to a compensation value corresponding to the liquid content of the aerosol-generation product <NUM>.

The electronic atomizing device <NUM> provided in the disclosure detects the liquid content of the aerosol-generation product <NUM> before heating the aerosol-generation product <NUM>, and outputs a corresponding heating curve according to the liquid content of the aerosol-generation product <NUM>. Therefore, the aerosol-generation products <NUM> with different liquid contents can be fully heated, thereby effectively improving user experience.

Operation S311 includes: collecting an electrical parameter between the first conductor and the second conductor in response to the first conductor and the second conductor that are spaced apart from each other being electrically connected by the aerosol-generation product.

Specifically, when the aerosol-generation product is inserted into the electronic atomizing device, the aerosol-generation product is in sufficiently contact with the first conductor, and electrically connects the first conductor to the second conductor. A sampling unit in the electronic atomizing device applies a voltage to the first conductor and the second conductor and collects the electrical parameter between the first conductor and the second conductor. The electrical parameter includes a capacitance value and/or a resistance value.

Operation S312 includes: obtaining the liquid content of the aerosol-generation product according to the electrical parameter.

Specifically, the control unit is connected to the sampling unit, and the control unit obtains the liquid content of the aerosol-generation product according to the electrical parameter collected by the sampling unit.

<FIG> is a flowchart of an implementation of operation S312 in <FIG> according to an embodiment of the disclosure. Operation S312 specifically includes the following operations.

Operation S313 includes: obtaining a first difference between the electrical parameter and the initial electrical parameter.

The initial electrical parameter is an electrical parameter when the first conductor and the second conductor are not electrically connected by the aerosol-generation product. Specifically, when the aerosol-generation product is not inserted into the electronic atomizing device, an electrical signal loop cannot be formed between the first conductor and the second conductor since the first conductor and the second conductor are spaced apart. In this case, the sampling unit denotes an electrical parameter between the first conductor and the second conductor as the initial electrical parameter.

Further, the sampling unit sends the collected initial electrical parameter and the obtained electrical parameter after the first conductor and the second conductor are electrically connected to the control unit. The control unit compares the initial electrical parameter collected by the sampling unit with the electrical parameter after the first conductor and the second conductor are electrically connected, and obtains the first difference between the two electrical parameters by algorithm filtering.

Operation S314 includes: comparing the first difference with a preset threshold to obtain a second difference.

Specifically, the control unit compares the first difference with the preset threshold pre-stored in the control unit again to obtain the second difference.

Operation S315 includes: obtaining the liquid content of the aerosol-generation product according to the second difference.

<FIG> is a flowchart of an implementation of operation S32 in <FIG> according to an embodiment of the disclosure. Operation S32 specifically includes the following operations.

Operation S321 includes: selecting a preset heating curve matching the liquid content of the aerosol-generation product from a pre-stored preset heating curve set.

Each of a preheating time and/or a preheating temperature in a preset heating curve in the preset heating curve set for preheating the aerosol-generation product varies from that in a different preset heating curve in the preset heating curve set. Specifically, a preset heating curve set corresponding to different liquid contents in the aerosol-generation product are pre-stored in the control unit, and each of the preheating time and/or the preheating temperature in the preset heating curve set for preheating the aerosol-generation product by using the heating element varies from that in the preset heating curve set. The control unit may select a preset heating curve matching the liquid content of the current aerosol-generation product from the pre-stored preset heating curve set to heat the aerosol-generation product.

Operation S322 includes: controlling, according to the preset heating curve, the heating element to increase or reduce the preheating time for the aerosol-generation product.

For example, when the liquid content of the aerosol-generation product is <NUM>, the time for preheating the aerosol-generation product by the electronic atomizing device is <NUM> seconds, the preheating temperature is <NUM> Celsius degrees, and the preset heating curve obtained by the control unit is a standard heating curve. When the liquid content of the aerosol-generation product is relatively high, the preset heating curve obtained by the control unit has a longer preheating time such as <NUM> seconds or <NUM> seconds for the aerosol-generation product than the standard heating curve or has a higher preheating temperature such as <NUM> Celsius degrees or <NUM> Celsius degrees for the aerosol-generation product than the standard heating curve. Alternatively, the preheating temperature and the preheating time for the aerosol-generation product both may be increased by a mixture manner, so that the aerosol-generation product can be preheated to a target temperature.

Alternatively, the standard heating curve may be a heating curve when the liquid content of the aerosol-generation product is a certain value. When the liquid content of the aerosol-generation product is lower than the certain value, the control unit may obtain a heating curve that has a shorter preheating time or a lower preheating temperature for the aerosol-generation product than the standard heating curve.

In another embodiment, different from the above operations S321-S322, operation S32 includes: compensating the pre-stored preset heating curve according to the liquid content of the aerosol-generation product, so as to change the preheating time and/or the preheating temperature in the preset heating curve for preheating the aerosol-generation product.

Specifically, a preset heating curve is stored in the control unit, and the preset heating curve corresponds to a certain value of the liquid content of the aerosol-generation product. After obtaining the liquid content of the aerosol-generation product, the control unit performs logical calculation on the preset heating curve to obtain and output a compensated heating curve, so as to increase or reduce the preheating time or the preheating temperature for the aerosol-generation product, so that the aerosol-generation product can be heated to a preset temperature. The control unit compensates for the preset heating curve before outputting the heating curve.

In the heating method of the electronic atomizing device provided in the disclosure, different heating curves may be outputted by the heating element according to the liquid content of the aerosol-generation product, so as to increase or reduce the preheating time or the preheating temperature for the aerosol-generation product, so that the aerosol-generation product can be heated to a preset temperature, thereby improving user experience.
