Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0017] First, let's introduce the terminology in this field.

[0018] Duty cycle, the duty cycle is the ratio of the high level time to the entire period 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.

[0019] By adjusting the on and off frequency of the controlled 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.

[0020] The controlled switch can be implemented using a MOS transistor, which can include a P-channel MOS transistor (Positive channel Metal Oxide Semiconductor, PMOS) and an N-channel MOS transistor (N-Metal-Oxide-Semiconductor, NMOS). These two types of MOS transistors have completely opposite power output performance.

[0021] For PMOS tubes, 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.

[0022] For NMOS tubes, the larger the duty cycle, the greater the output power of the power supply through the NMOS tube; the smaller the duty cycle, the smaller the output power of the power supply through the NMOS tube.

[0023] FIG1 shows a flow chart of an electronic atomizer status indication method provided by an embodiment of the present application. For ease of explanation, only the part related to the present embodiment is shown, which is described in detail below.

[0024] An embodiment of the present application provides an electronic atomizer status indication method, which may include the following steps S102 and S104.

[0025] 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.

[0026] In this embodiment, the electronic atomizer is provided with a heating element that generates heat when powered. A central control unit is connected to the heating element and can obtain the resistance value of the heating element in real time. The central control unit is connected to a controlled switch and can control the switching frequency of the controlled switch and the pulse width modulation duty cycle to adjust the energy supplied to the heating element. The controlled switch can be a field-effect transistor, a triode, a thyristor, or the like.

[0027] 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).

[0028] In step S104 , relevant parameters of a 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.

[0029] 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.

[0030] The suction force is positively correlated with the rate of change of the resistance value and the pulse width modulation duty cycle. Based on the rate of change of the resistance value and the pulse width modulation duty cycle, the corresponding suction force can be determined. Based on the suction force, parameters related to multiple indicator lights in the lamp are controlled.

[0031] The lamp may be a strip-shaped light bar or a ring-shaped light bar, and may be provided with a plurality of indicator lights, which may be light emitting diodes.

[0032] 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.

[0033] In this embodiment, when the puff force is relatively strong, the rate of change of the resistance value increases, and the PWM duty cycle also increases. When the puff force is relatively weak, the rate of change of the resistance value decreases, and the PWM duty cycle also decreases. Therefore, the magnitude of the puff force can be expressed by the rate of change of the resistance value and the PWM duty cycle.

[0034] The above-mentioned technical solution of the present application obtains the resistance value of the heating element in the electronic atomizer and the pulse width modulation duty cycle of the controlled switch, and controls the relevant parameters of multiple indicator lights according to the rate of change of the resistance value and the pulse width modulation duty cycle. The relevant parameters are used to indicate the user's current puffing strength. The user's current puffing strength can be represented by the relevant parameters of the indicator lights in a visual way, which helps the user determine the current puffing strength. The above-mentioned technical solution of the present application can realize the visual indication of the puffing strength without the need for additional sensors, thus reducing costs.

[0035] In some embodiments, the relevant parameters of the indicator light include: a lighting speed at which multiple indicator lights are lit in sequence.

[0036] In step S104 , the parameters related to 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.

[0037] Step S104 may include the following steps: comparing the rate of change of the resistance value with a first resistance value change rate threshold; 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, determining that the suction force is the first suction force; and controlling the lighting speed of the multiple indicator lights to light up in sequence to the first speed.

[0038] According to a preset first time interval, a high level pulse is sent to each indicator light in sequence to trigger each indicator light to turn on in sequence, and the turning-on speed of the indicator lights is a first speed.

[0039] In this embodiment, the controlled switch is an NMOS transistor, because the larger the pulse width modulation duty cycle of the NMOS transistor, 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.

[0040] 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.

[0041] A first resistance value change rate threshold and a first pulse width modulation duty cycle threshold can be preset. When the first resistance value change rate is greater than or equal to the first resistance value change rate threshold, and the first pulse width modulation duty cycle is greater than or equal to the first pulse width modulation duty cycle threshold, strong puffing can be determined. To indicate a state of strong puffing, a plurality of indicator lights can be controlled to illuminate sequentially at a first speed.

[0042] For example, the number of the plurality of indicator lights is 5, and the speed of lighting up the 5 indicator lights in sequence can be set to a first speed, which can be represented by the lighting time interval between every two adjacent indicator lights.

[0043] Exemplarily, the time interval between two adjacent indicator lights being turned on is, for example, 0.5 seconds.

[0044] 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 two adjacent indicator lights is, for example, 1 second.

[0045] In some embodiments, in step S104, controlling the lighting speed of the multiple indicator lights in sequence according to the rate of change of the resistance value and the pulse width modulation duty cycle may include the following steps: comparing the rate of change of the resistance value with a first resistance value change rate threshold; 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, determining that the suction force is the first suction force, and controlling the lighting speed of the multiple indicator lights in sequence to be the first speed.

[0046] In this embodiment, the controlled switch is a PMOS transistor, because a smaller PWM duty cycle of a PMOS transistor results in greater output power. If the PWM duty cycle is less than or equal to the fourth PWM duty cycle threshold, this indicates a higher power output. The puff intensity is determined to be the first puff intensity, and the multiple indicator lights are sequentially illuminated at the first speed.

[0047] The above-mentioned technical solution of the present application modifies the lighting speed of the indicator light by the suction force, and uses the lighting speed to represent the suction force, which helps the user to understand the current suction force in a timely manner and realizes effective human-computer interaction.

[0048] 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 status indication method may further include the following steps: determining the electronic atomizer status according to the above resistance value and the pulse width modulation duty cycle; determining the indication signal of the indicator light according to the above electronic atomizer status; the above indication signal is used to indicate that the user is inhaling the above electronic atomizer.

[0049] In this embodiment, the electronic atomizer states include a puffing state and a non-puffing state. The current electronic atomizer state is determined based on the aforementioned resistance value and the pulse width modulation duty cycle. An indicator light for the puffing state and an indicator light for the non-puffing state can be set. Different indicator light signals can be represented, for example, by different colors, by different numbers of on and off indicators, or by different lighting speeds.

[0050] 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.

[0051] In some embodiments, the electronic atomizer state is determined based on the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may include the following steps: comparing the resistance value 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, determining that the electronic atomizer state is a puffing state.

[0052] In this embodiment, the controlled switch is an NMOS transistor, because the greater the pulse width modulation duty cycle of the NMOS transistor, 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 a greater power output. The electronic atomizer is determined to be in the puffing state.

[0053] 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 value threshold, and the pulse width modulation duty cycle is greater than or equal to the above-mentioned second pulse width modulation duty cycle threshold, it can be determined that the electronic atomizer is in the puffing state.

[0054] In some embodiments, the electronic atomizer state is determined based on the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may include the following steps: comparing the resistance value 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, determining that the electronic atomizer state is a puffing state.

[0055] In this embodiment, the controlled switch is a PMOS transistor, because the smaller the pulse width modulation duty cycle of the PMOS transistor, 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, it indicates that a higher power output is available. It can be determined that the electronic atomizer is in the puffing state.

[0056] 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 lighting of the lamp.

[0057] In this embodiment, after determining that the state of the electronic atomizer is the puffing state, the lamp can be controlled to light up to indicate that the current state of the electronic atomizer is the puffing state. Multiple indicator lights can be controlled to light up simultaneously, or each indicator light can be controlled to light up in sequence.

[0058] In some embodiments, the electronic atomizer state is determined based on the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may include the following steps: comparing the pulse width modulation duty cycle 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, determining that the current electronic atomizer state is a stopped inhalation state.

[0059] In this embodiment, the controlled switch is an NMOS transistor. When the electronic atomizer is in the inhalation-free state, the pulse width modulation duty cycle decreases. 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, the electronic atomizer is determined to be in the inhalation-free state.

[0060] In some embodiments, the electronic atomizer state is determined based on the resistance value and the pulse width modulation duty cycle, and the electronic atomizer state indication method may include the following steps: comparing the pulse width modulation duty cycle 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, determining that the current electronic atomizer state is a stopped inhalation state.

[0061] In this embodiment, the controlled switch is a PMOS transistor, because the larger the pulse width modulation duty cycle of the PMOS transistor, the smaller the output power. If 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 the inhalation stop state.

[0062] In some embodiments, after determining that the current state of the electronic atomizer is the puffing state, the method may further include the following steps: controlling the pulse width modulation duty cycle of the controlled switch so that the temperature of the heating element is close to the temperature control target temperature.

[0063] 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 device. Therefore, the temperature of the heating element needs to be controlled to maintain the temperature at the target temperature, so as to improve the user experience.

[0064] The temperature of the heating element is affected by a variety of factors. The relationship between the temperature of the heating element, the PWM duty cycle, and the resistance value is 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 increases. If the PWM duty cycle increases, the electric power applied to the heating element increases, and the heating element temperature rises. If the PWM duty cycle decreases, the electric power consumed by the heating element decreases, and the heating element temperature decreases.

[0065] According to the above relationship, it can be seen 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 achieve constant temperature control under ideal conditions.

[0066] 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, which will cause 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.

[0067] Therefore, to mitigate the aforementioned airflow influence, during the actual control of the puffing state, the pulse width modulation duty cycle of the controlled switch can be controlled to bring the temperature of the heating element close to the temperature control target temperature. Specifically, the pulse width modulation duty cycle can be adjusted based on the resistance value of the heating element, with the pulse width modulation duty cycle being adjusted based on the resistance value under the ideal control state. This eliminates the influence of airflow during the puffing process.

[0068] 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: controlling the pulse width modulation duty cycle to adjust the temperature of the heating element to be close to the temperature control target temperature.

[0069] In this embodiment, in an actual scenario, when the puffing 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 achieved.

[0070] To achieve the target temperature, the solution is to adjust the PWM duty cycle mentioned above. If the controlled switch is an NMOS transistor, the actual PWM duty cycle can be adjusted to be less than the theoretical PWM duty cycle, which helps to lower the actual temperature of the heating element to achieve the target temperature. If the controlled switch is a PMOS transistor, the actual PWM duty cycle can be adjusted to be greater than the theoretical PWM duty cycle, which helps to lower the actual temperature of the heating element to achieve the target temperature.

[0071] In some embodiments, after determining that the current electronic atomizer state is the inhalation-stopped state, the electronic atomizer state indication method may further include the following steps: controlling multiple indicator lights to turn off.

[0072] In this embodiment, after the central control unit determines that the electronic atomizer is in the inhalation-free state, it can control the multiple indicator lights to turn off. Specifically, the central control unit can send a low-level pulse to each indicator light to turn each indicator light off. The low-level pulse can be sent to multiple indicator lights simultaneously to turn them off simultaneously, or the low-level pulse can be sent to each indicator light sequentially to turn them off sequentially.

[0073] A control method for an electronic atomizer is described in detail below. The method may include the following steps.

[0074] First, let's introduce the temperature control of the heating element, as well as the changing pattern of the PWM duty cycle and the resistance of the heating element in the puffing state and the puffing stop state. This pattern is used to detect the puffing state and judge the puffing strength. The temperature control of the heating element is explained 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 with the heating element to control 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, controlling the actual temperature of the heating element to the target temperature.

[0075] During the suction state, the airflow will take away the heat, lowering the temperature of the heating element. The resistance of the heating element will become smaller, 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 heating element temperature to the target temperature.

[0076] When the pumping is stopped, the PID algorithm has a certain hysteresis, which causes 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.

[0077] 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.

[0078] 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 puffing state, the PWM duty cycle will increase, but due to the effect of 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 puffing state.

[0079] 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 puff state determination.

[0080] In the second step, the user's suction strength can be judged based on the change rate of the PWM duty cycle and the resistance value of the heating element.

[0081] In the third step, based on the first step, it is determined that the user is in the puffing state, and the current state is the puffing state, and a light indication is performed, such as the light gradually lights up. Based on the second step, the user's puffing strength is determined, and the light indication speed is adjusted, such as the greater the puffing strength, the faster the light lights up.

[0082] In the fourth step, when the puffing action stops, the current state is determined to be 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. For example, all lights are turned off to indicate that puffing has stopped.

[0083] This application proposes a method for detecting and indicating the puffing state of an electronic atomizer, which can detect the puffing state and force without adding additional hardware sensors, and can meet the user's interactive needs during the puffing process.

[0084] In the second aspect, referring to FIG. 2 , the present application proposes an electronic atomizer status indicating device 2 , comprising: an acquisition module 21 and a control module 22 .

[0085] Among them, the acquisition module 21 is used to obtain 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.

[0086] 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-mentioned resistance value and the above-mentioned pulse width modulation duty cycle.

[0088] According to a preset first time interval, a high level pulse is sent to each indicator light in sequence to trigger each indicator light to turn on in sequence, and the turning-on speed of the above indicator lights is a first speed.

[0094] In some embodiments, the control module 22 is further configured to control the lighting of the lamp after determining that the electronic atomizer is in the puffing state.
