[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] First, let’s introduce some terminology in this field:

[0024] Duty cycle: Duty cycle is the ratio of the high level time to the entire periodic signal time in a periodic signal. For example: the high level time is t and the entire period time is T, then the duty cycle is D=t / T.

[0025] By adjusting the on-off frequency of the switch and using pulse width modulation (PWM) technology, the duty cycle can be adjusted, thereby adjusting the amount of electrical energy applied to the load by the power supply.

[0026] The above switch can be implemented by MOS tube, which can include P-channel MOS tube (positive channel Metal Oxide Semiconductor, PMOS) and N-channel MOS tube (N-Metal-Oxide-Semiconductor, NMOS). The above two MOS tubes have completely opposite power output performance.

[0027] For the PMOS tube, the larger the duty cycle, the smaller the output power of the power supply through the PMOS tube; the smaller the duty cycle, the greater the output power of the power supply through the PMOS tube.

[0028] For NMOS tubes, the larger the duty cycle, the greater the output power of the power supply through the PMOS tube; the smaller the duty cycle, the smaller the output power of the power supply through the PMOS tube.

[0029] Figure 1 A flow chart of an electronic atomizer state indication method provided by an embodiment of the present application is shown. For the sake of convenience, only the part related to the present embodiment is shown, which is described in detail as follows:

[0030] An electronic atomizer status indication method may include the following steps:

[0031] In step S102, the resistance value of the heating element in the electronic atomizer and the pulse width modulation duty cycle of the controlled switch are obtained. The controlled switch controls the resistance value of the heating element through the pulse width modulation duty cycle.

[0032] In this embodiment, a heating element is provided in the electronic atomizer, and the heating element is heated and generates heat after being powered on. The central control unit can be connected to the heating element, and the resistance value of the heating element can be obtained in real time. The central control unit is connected to the controlled switch, and the switching frequency of the controlled switch can be controlled, and the pulse width can be controlled to adjust the duty cycle to adjust the energy applied to the heating element by the power supply. The controlled switch can be a field effect tube, a triode, a thyristor, etc.

[0033] In this embodiment, the central control unit may use a proportional integral derivative (PID) algorithm to control the temperature of the heating element, and the controlled switch may be a metal-oxide-semiconductor field effect transistor (MOS).

[0034] In step S104, the relevant parameters of the plurality of indicator lights in the lamp on the electronic atomizer are controlled according to the change rate of the resistance value and the pulse width modulation duty cycle.

[0035] In this embodiment, the relevant parameters of the indicator light include, but are not limited to, the brightness of the indicator light, the brightness distribution of multiple indicator lights, the color of the indicator light, the color distribution of multiple indicator lights, the speed at which the indicator lights light up in sequence, and the flashing frequency of the indicator light.

[0036] The suction strength is positively correlated with the change rate of the resistance value and the pulse width modulation duty cycle. According to the change rate of the resistance value and the pulse width modulation duty cycle, the corresponding suction strength can be determined. According to the suction strength, the relevant parameters of the multiple indicator lights in the lamp are controlled.

[0037] The lamp may be a strip-shaped light bar or a ring-shaped light bar, and a plurality of indicator lights are arranged on the lamp. The indicator lights may be light emitting diodes.

[0038] In this embodiment, the central control unit is connected to each indicator light and sends a high level pulse to each indicator light to light up each indicator light. The time interval between the high level pulses of two adjacent indicator lights can be controlled and shortened to increase the lighting speed of the indicator lights.

[0039] In this embodiment, when the suction force is relatively large, the change rate of the resistance value will increase, and the pulse width modulation duty cycle will also increase. When the suction force is relatively small, the change rate of the resistance value will decrease, and the pulse width modulation duty cycle will also decrease. Therefore, the magnitude of the suction force can be expressed by the change rate of the resistance value and the above-mentioned pulse width modulation duty cycle.

[0040] The above-mentioned technical solution of the present application, the resistance value of the heating element in the electronic atomizer, and the pulse width modulation duty cycle of the controlled switch, control the relevant parameters of multiple indicator lights according to the change rate of the resistance value and the pulse width modulation duty cycle, and the relevant parameters are used to indicate the current suction strength of the user. The current suction strength of the user can be represented by the relevant parameters of the visual indicator lights, which is helpful for the user to determine the current suction strength. The above-mentioned technical solution of the present application can realize the visual indication of the suction strength without the need for additional sensors, thereby reducing costs.

[0041] In some embodiments, the relevant parameters of the indicator light include: a lighting speed at which multiple indicator lights are lit in sequence.

[0042] In step S104, the lighting speed of the plurality of indicator lights being sequentially lit up according to the change rate of the resistance value and the pulse width modulation duty cycle may further include the following steps:

[0043] The rate of change of the resistance value is compared with a first resistance value change rate threshold, and in response to the rate of change of the resistance value being greater than or equal to the first resistance value change rate threshold, and the pulse width modulation duty cycle being greater than or equal to the first pulse width modulation duty cycle threshold, the suction force is determined to be the first suction force, and the lighting speed of the multiple indicator lights is controlled to be the first speed.

[0044] According to a preset first time interval, a high level pulse is sent to each indicator light in turn to trigger each indicator light to turn on in turn, and the turning-on speed of the indicator lights is a first speed.

[0045] In this embodiment, the switch is an NMOS tube, because the larger the pulse width modulation duty cycle of the NMOS tube, the greater the output power. If the pulse width modulation duty cycle is greater than the first pulse width modulation duty cycle threshold, it indicates that there is a greater power output.

[0046] The first time interval is inversely proportional to the first speed. The greater the first speed, the smaller the first time interval, and the smaller the first speed, the larger the second time interval. In this way, by modifying the first time interval, the speed at which the multiple indicator lights are lit in sequence can be adjusted.

[0047] A first resistance value change rate threshold value and a first pulse width modulation duty cycle threshold value may be preset, and when the first resistance value change rate is greater than or equal to the first resistance value change rate threshold value, and the first pulse width modulation duty cycle is greater than or equal to the first pulse width modulation duty cycle threshold value, it may be determined that the suction is strong. In order to indicate the state of the suction, the lighting speed of the multiple indicator lights may be controlled to be a first speed.

[0048] Exemplarily, the number of the multiple indicator lights is 5, and the speed of lighting up the 5 indicator lights in sequence can be set to a first speed, and the first speed can be represented by the lighting time interval of every two adjacent indicator lights.

[0049] Exemplarily, the time interval between two adjacent indicator lights being turned on is, for example, 0.5 seconds.

[0050] In the state of stopping suction, the speed of lighting up the five indicator lights in sequence can be set to the second speed, and the time interval between lighting up every two adjacent indicator lights is, for example, 1 second.

[0051] In some embodiments, in step S104, controlling the lighting speed of the multiple indicator lights in sequence according to the change rate of the resistance value and the pulse width modulation duty cycle may further include the following steps:

[0052] The rate of change of the resistance value is compared with a first resistance value change rate threshold, and in response to the rate of change of the resistance value being greater than or equal to the first resistance value change rate threshold, and the pulse width modulation duty cycle being less than or equal to a fourth pulse width modulation duty cycle threshold, the suction force is determined to be the first suction force, and the lighting speed of the multiple indicator lights is controlled to be the first speed.

[0053] In this embodiment, the switch is a PMOS tube, because the smaller the pulse width modulation duty cycle of the PMOS tube, the greater the output power. If the pulse width modulation duty cycle is less than or equal to the fourth pulse width modulation duty cycle threshold, it indicates that there is a greater power output. The suction strength is determined to be the first suction strength, and the lighting speed of the multiple indicator lights is controlled to be the first speed.

[0054] The above-mentioned technical solution of the present application modifies the lighting speed of the light-emitting body by the suction force, and uses the lighting speed to represent the suction force, which is beneficial for the user to understand the current suction force in time and realizes effective human-computer interaction.

[0055] In some embodiments, in step S102, after obtaining the resistance value of the heating element in the electronic atomizer and the pulse width modulation duty cycle of the controlled switch, the electronic atomizer state indication method may further include the following steps:

[0056] The electronic atomizer state is determined according to the resistance value and the pulse width modulation duty cycle.

[0057] According to the state of the electronic atomizer, an indication signal of the indicator light is determined; the indication signal is used to indicate that the user is inhaling the electronic atomizer.

[0058] In this embodiment, the electronic atomizer state includes a puffing state and a stop puffing state. The current electronic atomizer state is determined according to the above resistance value and the pulse width modulation duty cycle. The indication signal of the indicator light of the puffing state and the indication signal of the indicator light of the stop puffing state can be set. Different indication signals of the indicator light can be, for example, different colors can be used to represent different indication signals, different numbers of indicator lights that light up and go out can be used to represent different indication signals, or different lighting speeds can be used to represent different indication signals.

[0059] The above-mentioned technical solution of the present application determines the state of the electronic atomizer according to the above-mentioned resistance value and pulse width modulation duty cycle, which is beneficial for the user to determine the current state of the electronic atomizer in a timely manner, is beneficial for human-computer interaction, and improves the user's experience of using the electronic atomizer.

[0060] In some embodiments, the electronic atomizer state is determined according to the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may further include the following steps:

[0061] The resistance value is compared with the first resistance value threshold, and in response to the resistance value being less than or equal to the first resistance value threshold and the pulse width modulation duty cycle being greater than or equal to the second pulse width modulation duty cycle threshold, the electronic atomizer state is determined to be a puffing state.

[0062] In this embodiment, the switch is an NMOS tube, because the larger the pulse width modulation duty cycle of the NMOS tube, the greater the output power. If the pulse width modulation duty cycle is greater than the second pulse width modulation duty cycle threshold, it indicates that there is a greater power output. It is determined that the state of the electronic atomizer is the inhalation state.

[0063] When the electronic atomizer is in the puffing state, the resistance of the heating element will decrease due to the airflow taking away heat. When the resistance of the heating element decreases and is less than or equal to the first resistance threshold, and the pulse width modulation duty cycle is greater than or equal to the above-mentioned second pulse duty cycle threshold, it can be determined that the electronic atomizer is in the puffing state.

[0064] In some embodiments, the electronic atomizer state is determined according to the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may further include the following steps:

[0065] The resistance value is compared with the first resistance value threshold, and in response to the resistance value being less than or equal to the first resistance value threshold and the pulse width modulation duty cycle being less than or equal to a fifth pulse width modulation duty cycle threshold, the electronic atomizer state is determined to be a puffing state.

[0066] In this embodiment, the switch is a PMOS tube, because the smaller the pulse width modulation duty cycle of the PMOS tube, the greater the output power. If the pulse width modulation duty cycle is less than or equal to the fifth pulse width modulation duty cycle threshold value, it indicates that there is a greater power output. It can be determined that the state of the electronic atomizer is the inhalation state.

[0067] In some embodiments, after determining that the electronic atomizer state is the inhalation state, the electronic atomizer state indication method may further include the following steps: controlling the lamp to light up.

[0068] In this embodiment, after determining that the state of the electronic atomizer is the inhalation state, the lamp can be controlled to light up to indicate that the current state of the electronic atomizer is the inhalation state. Multiple indicator lights can be controlled to light up at the same time, or each indicator light can be controlled to light up in sequence.

[0069] In some embodiments, the electronic atomizer state is determined according to the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may further include the following steps:

[0070] The pulse width modulation duty cycle is compared with a third pulse width modulation duty cycle threshold, and in response to the pulse width modulation duty cycle being less than or equal to the third pulse width modulation duty cycle threshold, it is determined that the current state of the electronic atomizer is a stop-inhalation state.

[0071] In this embodiment, the switch is an NMOS tube, and when the electronic atomizer is in the stop-puff state, the pulse width modulation duty cycle will decrease, and a third pulse width modulation duty cycle threshold can be preset. When the pulse width modulation duty cycle is less than or equal to the third pulse width modulation duty cycle threshold, it is determined that the electronic atomizer is in the stop-puff state.

[0072] In some embodiments, the electronic atomizer state is determined according to the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may further include the following steps:

[0073] The pulse width modulation duty cycle is compared with a sixth pulse width modulation duty cycle threshold, and in response to the pulse width modulation duty cycle being greater than or equal to the sixth pulse width modulation duty cycle threshold, it is determined that the current state of the electronic atomizer is a stop-inhalation state.

[0074] In this embodiment, the switch is a PMOS tube, because the larger the pulse width modulation duty cycle of the PMOS tube, the smaller the output power. When the pulse width modulation duty cycle is greater than or equal to the sixth pulse width modulation duty cycle threshold, it can be determined that the current state of the electronic atomizer is a stop puffing state.

[0075] In some embodiments, after determining that the current state of the electronic atomizer is the inhalation state, the method may further include the following steps:

[0076] The pulse width modulation duty cycle of the controlled switch is controlled so that the temperature of the heating element is close to the temperature control target temperature.

[0077] In this embodiment, the heating element generates heat when it is powered on. If the temperature is too high, it is not convenient to hold the hand. Therefore, the temperature of the heating element needs to be controlled at a constant temperature so that the temperature of the heating element is maintained at a target temperature. This can improve the user experience.

[0078] The temperature of the heating element is affected by many factors. The temperature of the heating element, the PWM duty cycle, and the change rules of the resistance value are as follows: the temperature of the heating element and the resistance value of the heating element are linearly related. If the temperature of the heating element decreases, the resistance value of the heating element decreases; if the temperature of the heating element increases, the resistance value of the heating element will increase. If the PWM duty cycle increases, the electric power applied to the heating element will increase, and the temperature of the heating element will increase. If the PWM duty cycle decreases, the electric power consumed by the heating element will decrease, and the temperature of the heating element will decrease.

[0079] According to the above relationship, it can be known that the temperature of the heating element can be expressed by the resistance value of the heating element, and the temperature of the heating element can be adjusted by adjusting the PWM duty cycle. Based on the above relationship, in order to achieve the purpose of constant temperature control of the heating element, the proportional integral differential PID algorithm can be used for control. Of course, other control algorithms in automatic control theory can also be used for control. When the above PID algorithm is used for control, the resistance value of the heating element can be collected, and the PWM duty cycle can be adjusted according to the resistance value of the heating element, so as to perform constant temperature control under ideal conditions.

[0080] However, in actual scenarios, under the suction state, there is another important factor that affects the temperature of the heating element, that is, the influence of the airflow during the suction process. Because under the suction state, the airflow generated by the suction will take away the heat, causing the temperature of the heating element to drop. The actual temperature of the heating element will be lower than the target temperature, and the resistance value of the heating element will be lower than the resistance value under the ideal control state.

[0081] Therefore, in order to adjust the influence of the above-mentioned airflow, during the actual control of the suction state, the pulse width modulation duty cycle of the controlled switch can be controlled so that the temperature of the heating element is close to the temperature control target temperature. Specifically, the pulse width modulation duty cycle can be adjusted according to the resistance value of the heating element, and the pulse width modulation duty cycle can be adjusted with the resistance value under the above-mentioned ideal control state as the target. Thus, the influence of airflow during the suction process is eliminated.

[0082] In some embodiments, after determining that the electronic atomizer state is in the stopped inhalation state, the electronic atomizer state indication method may further include the following steps:

[0083] The pulse width modulation duty cycle is controlled to adjust the temperature of the heating element to be close to the temperature control target temperature.

[0084] In this embodiment, in an actual scenario, when the suction is stopped, if the theoretical PID control is performed with an ideal PWM duty cycle, the PID algorithm has a certain lag, resulting in control overshoot, that is, the actual temperature of the heating element will be higher than the target temperature, and the target temperature cannot be obtained.

[0085] In order to obtain the target temperature, the solution is to adjust the above PWM duty cycle. If the switch is an NMOS tube, the actual PWM duty cycle can be adjusted to be less than the theoretical PWM duty cycle, which is conducive to lowering the actual temperature of the heating element and obtaining the target temperature. If the switch is a PMOS tube, the actual PWM duty cycle can be adjusted to be greater than the theoretical PWM duty cycle, which is conducive to lowering the actual temperature of the heating element and obtaining the target temperature.

[0086] In some embodiments, after determining that the current state of the electronic atomizer is the stopped inhalation state, the electronic atomizer state indication method may further include the following steps:

[0087] Control multiple indicator lights to turn off.

[0088] In this embodiment, after the central control unit determines that the state of the electronic atomizer is the stop-inhalation state, it can control multiple indicator lights to turn off. Specifically, the central control unit can send a low-level pulse to each indicator light, so that each indicator light is turned off. A low-level pulse can be sent to multiple indicator lights at the same time, so that multiple indicator lights are turned off at the same time, or a low-level pulse can be sent to each indicator light in turn, so that multiple indicator lights are turned off in turn.

[0089] The following is a detailed description of a control method for an electronic atomizer, which may include the following steps:

[0090] First, let's introduce the temperature control of the heating element, as well as the changing rules of the PWM duty cycle and the resistance of the heating element in the puffing state and the puffing stop state. This rule is used to detect the puffing state and judge the puffing strength. The temperature control of the heating element is described as follows: When heating the electronic atomizer, the PID algorithm is used to control the temperature of the heating element. The PID algorithm controls the output power of the power supply through the MOS tube by controlling the PWM duty cycle. The MOS tube is connected in series to the heating element, thereby controlling the temperature of the heating element. When the actual temperature is not equal to the target temperature, the PID algorithm adjusts the PWM duty cycle to adjust the output power of the power supply through the MOS tube, and controls the actual temperature of the heating element to the target temperature.

[0091] In the suction state, the airflow will take away the heat, lowering the temperature of the heating element, reducing the resistance of the heating element, and the actual temperature will be lower than the target temperature of the temperature control. The PID algorithm controls the PWM duty cycle and adjusts the MOS tube power to restore the temperature of the heating element to the target temperature.

[0092] When the pumping stops, the PID algorithm will have a certain lag, resulting in control overshoot, that is, the actual temperature will be higher than the target temperature. The sampling PID algorithm adjusts the PWM duty cycle, reduces the output power of the voltage passing through the MOS tube, and adjusts the actual temperature to the target temperature.

[0093] The following uses NMOS as an example to illustrate that the larger the PWM duty cycle, the higher the output power of the power supply through the NMOS tube, and the higher the temperature of the heating element.

[0094] The first step is to start heating. After preheating, the PWM duty cycle and the resistance value of the heating element are continuously detected. In the suction state, the PWM duty cycle will increase, but due to the effect of the airflow, the actual resistance value of the heating element will decrease. When the PWM duty cycle is greater than or equal to the second pulse width modulation duty cycle threshold and the resistance value of the heating element is less than or equal to the first resistance value threshold, it is determined that the current state is the suction state.

[0095] The above two conditions of PWM duty cycle and heating element resistance are used for judgment in order to eliminate interference and improve the accuracy of the determination of the puffing state.

[0096] In the second step, the user's suction strength can be determined based on the change rate of the PWM duty cycle and the resistance value of the heating element.

[0097] The third step is to determine, based on the first step, whether the user is inhaling and the current state is the inhaling state, and to provide light indication, such as the light gradually lights up. Based on the second step, determine the user's inhalation strength and adjust the light indication speed, such as the greater the inhalation strength, the faster the light lights up.

[0098] In the fourth step, after the puffing action is stopped, it is determined that the current state is the puffing stop state, and the PWM duty cycle will be reduced. When the PWM duty cycle is less than or equal to the third pulse width modulation duty cycle threshold, it is determined that the user has stopped puffing, and a light indication is given, such as turning off all the lights to indicate that the puffing has stopped.

[0099] The present application proposes a method for detecting and indicating the puffing state of an electronic atomizer, which can detect the puffing state and strength without adding additional hardware sensors, and can meet the user's interactive needs during the puffing process.

[0100] Second, see Appendix Figure 2 As shown, the present application proposes an atomizer state indicating device 2, comprising:

[0101] The acquisition module 21 is used to acquire the resistance value of the heating element in the electronic atomizer and the pulse width modulation duty cycle of the controlled switch; the controlled switch controls the resistance value of the heating element through the pulse width modulation duty cycle;

[0102] The control module 22 is used to control relevant parameters of multiple indicator lights in the lamp on the electronic atomizer according to the change rate of the above resistance value and the above pulse width modulation duty cycle.

[0103] In some embodiments, the control module 22 is also used to, in response to the rate of change of the resistance value being greater than or equal to a first resistance value change rate threshold, and the pulse width modulation duty cycle being greater than or equal to a first pulse width modulation duty cycle threshold, determine that the suction force is a first suction force; and control the lighting speed of multiple indicator lights to be lit up in sequence to be a first speed.

[0104] According to a preset first time interval, a high level pulse is sent to each indicator light in turn to trigger each indicator light to turn on in turn, and the turning-on speed of the above indicator lights is a first speed.

[0105] In some embodiments, the control module 22 is further used to compare the rate of change of the resistance value with a first resistance value change rate threshold, and in response to the rate of change of the resistance value being greater than or equal to the first resistance value change rate threshold, and the pulse width modulation duty cycle being less than or equal to a fourth pulse width modulation duty cycle threshold, determine that the suction force is the first suction force, and control the lighting speed of multiple indicator lights to be lit up in sequence to be the first speed.

[0106] In some embodiments, the control module 22 is further used to determine the electronic atomizer state according to the resistance value and the pulse width modulation duty cycle.

[0107] According to the state of the electronic atomizer, an indication signal of the indicator light is determined; the indication signal is used to indicate that the user is inhaling the electronic atomizer.

[0108] In some embodiments, the control module 22 is further used to determine that the electronic atomizer state is a puffing state in response to the resistance value being less than or equal to a first resistance value threshold and the pulse width modulation duty cycle being greater than or equal to a second pulse width modulation duty cycle threshold.

[0110] In some embodiments, the control module 22 is further used to control the lighting of the lamp after determining that the state of the electronic atomizer is the inhalation state.

[0111] In some embodiments, the control module 22 is further configured to, in response to the pulse width modulation duty cycle being less than or equal to a third pulse width modulation duty cycle threshold, determine that the electronic atomizer state is a stop-inhalation state.
