Description

Technical Field

[0001] This application relates to the field of atomization, and in particular to a control method, control circuit and atomization device for an atomization device. Background Technology

[0002] An atomizing device is an electronic product that can atomize the atomizing matrix stored inside to obtain an aerosol. The atomizing device is equipped with buttons, which can be used to trigger the corresponding functions of the atomizing device, such as starting, selecting or switching working modes, etc.

[0003] However, during the transportation of the atomizing device, it is easily subjected to external force, which may cause the button to be operated or triggered incorrectly, resulting in accidental touch. This causes the atomizing device to activate the function corresponding to the button without human intervention, which increases the abnormal wear and tear on the atomizing device's battery. Summary of the Invention

[0004] The embodiments of this application provide a control method, control circuit, and atomizing device for an atomizing device, which can reduce accidental button presses on the atomizing device and reduce abnormal battery wear.

[0005] In a first aspect, embodiments of this application provide a control method for an atomizing device, the atomizing device including a button, and further including: acquiring a trigger signal of the button and at least one sensing signal, the sensing signal being used to reflect the trigger source of the trigger signal; determining whether the button is normally triggered based on the trigger signal and at least one sensing signal; if so, executing the function triggered by the button.

[0006] In some embodiments, determining whether the button is normally triggered based on the trigger signal and at least one of the sensing signals includes: when the trigger signal and at least one of the sensing signals are obtained, determining that the button is normally triggered.

[0007] In some embodiments, the trigger signal is a press trigger signal or a touch trigger signal, and the sensing signal includes a touch signal and a temperature signal; determining whether the button is normally triggered based on the trigger signal and at least one of the sensing signals includes: determining that the button is normally triggered when the press trigger signal and the touch signal and / or the temperature signal are obtained; or determining that the button is normally triggered when the touch trigger signal and the temperature signal are obtained.

[0008] In some embodiments, the button is configured to trigger the atomizing device to turn on or off. The atomizing device system has a low-power operation mode and a normal operation mode. The low-power operation mode is the default state of the atomizing device system, and the normal operation mode is the working state in which the atomizing device performs atomization work. When it is determined that the button is normally triggered, the atomizing device executes the normal operation mode. Determining whether the button is normally triggered based on the trigger signal and at least one of the sensing signals includes: if the trigger signal or the sensing signal is obtained, and it is determined that the button is not normally triggered, then the atomizing device system maintains the low-power operation mode.

[0009] Secondly, embodiments of this application provide a control circuit for an atomizing device, comprising: a main control chip; a first circuit, the first circuit including a button, the button having at least one sensor; one end of the first circuit being connected to the main control chip to obtain a trigger signal from the button; at least one second circuit, one end of the second circuit being connected to the sensor, and the other end of the second circuit being connected to the main control chip to obtain a sensing signal from the button through the sensor; wherein, the main control chip is configured to receive the trigger signal and the sensing signal, and execute the function triggered by the button according to the received result.

[0010] In some embodiments, the main control chip is configured to execute the function triggered by the button when it receives the trigger signal and the sensing signal.

[0011] In some embodiments, the button includes a first end and a second end, the first end being grounded; the first circuit further includes a first resistor, one end of which is connected to the battery of the atomizing device, and the other end of which is connected to a pin of the main control chip and the second end of the button, respectively.

[0014] Thirdly, embodiments of this application provide an atomizing device, wherein the atomizing device employs the control circuit described in the above embodiments.

[0015] The beneficial effects of this application are: this application determines whether the button is in a normal triggering state by obtaining the button's own trigger signal and the sensing signal that can reflect the button's trigger source, thereby reducing accidental button presses and reducing abnormal battery wear of the atomizing device. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a flowchart of the control method in some embodiments of this application; Figure 2 This is a flowchart of the control method of some other embodiments in this application; Figure 3 This is a schematic diagram of the control circuit of some embodiments of this application. Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Firstly, during the transportation of the atomizer, its buttons are easily triggered by external force, leading to accidental button presses. These accidental presses cause the atomizer's main control chip to be prematurely awakened and activated without human intervention, thus increasing abnormal battery wear and potentially causing users to experience low battery voltage. In some cases, due to prolonged transportation, the atomizer may arrive at the user's hands with a battery voltage as low as 0V, preventing it from powering on.

[0020] To address the aforementioned issues, some embodiments employ a technique of adding lithium batteries to protect the chip. However, this technique typically only activates protection when the battery voltage is over-discharged to 2.8V, impacting the user's power-on / off experience. Furthermore, this setup also increases the internal resistance of the atomizing device and reduces battery conversion efficiency. Therefore, this application proposes an alternative solution.

[0021] Please refer to Figure 1The embodiments of this application provide a control method for an atomizing device, the atomizing device including a button, and further including step S10: acquiring a trigger signal of the button and at least one sensing signal, the sensing signal being used to reflect the trigger source of the trigger signal.

[0022] The user can control the atomizing device by operating buttons, such as turning it on and off, selecting and switching modes, and choosing the operating time. In step S10, the trigger signal and sensing signal of the button are acquired to help determine whether the button has been triggered. Furthermore, the trigger signal provides feedback on whether the button has been triggered, while the sensing signal reflects the trigger source; in other words, the sensing signal indicates the object that triggered the button, thus helping to determine whether the button was manually triggered.

[0023] Please continue to refer to this. Figure 1 The control method further includes step S20: determining whether the button has been properly triggered based on the trigger signal and at least one sensing signal. In step S20, the trigger signal and the sensing signal are used together as conditions for determining whether the button has been properly triggered, in order to improve the accuracy of the determination and reduce erroneous start-up of the atomizing device caused by accidental button presses.

[0024] Please continue to refer to this. Figure 1 The control method also includes step S30: if so, then execute the function triggered by the button. In step S30, when it is determined through step S20 that the button is normally triggered, that is, manually operated to trigger the button, the atomizing device will execute the function corresponding to the button. Otherwise, the button will not trigger the corresponding function, that is, the atomizing device will not execute the function corresponding to the button. In this way, the accidental button press can be reduced.

[0025] In some embodiments, please refer to Figure 2The optimization step S20 specifically includes: when a trigger signal and at least one sensing signal are obtained, determining that the button has been normally triggered. Specifically, the button may be triggered manually or by external force. If the trigger signal or sensing signal is used to determine the button's triggering status, the accuracy of the determination will be insufficient. Therefore, the determination condition used in step S20 requires that both a trigger signal and at least one sensing signal be obtained simultaneously. This setting improves the accuracy of button trigger determination. In other words, when the user manually operates the button, both a trigger signal and a sensing signal are provided. The sensing signal can trigger one or more buttons, while when the button is accidentally pressed, a trigger signal is provided. For example, when using a press button, manually pressing the button causes it to move within a preset pressing stroke (the pressing part moves relative to the switch and contacts the switch), thus triggering the button. However, under other external forces, the button may also become stuck, or other objects may apply pressure to the button, causing it to move within the preset pressing stroke and trigger the button. For example, when using touch buttons, human contact can trigger the button (the structure of a touch button can use existing technology, which will not be elaborated here), but the touch button may also be triggered by contact with other objects. Based on these situations, in step S20, two signals are used as judgment conditions to reduce accidental touches caused by non-human operation.

[0026] In some embodiments, the button can be a press button, and further, the trigger signal can be a press trigger signal. For example, when a user touches and presses the button with their finger, the press trigger signal of the button can be obtained through step S10.

[0027] In some scenarios, the atomizing device may be triggered by pressing the button under external force during transportation or storage. Therefore, to further improve the accuracy of button trigger detection, a sensing signal is also acquired in step S10. Specifically, the sensing signal is a signal that can reflect the action of a human body touching the button. Specifically, the sensing signal can include a touch signal and a temperature signal. The touch signal is the signal triggered when the skin of a finger touches the button, and the temperature signal is the corresponding temperature signal obtained when the skin touches the button, since the skin has a temperature.

[0028] Furthermore, step S20 can be optimized as follows: when a press trigger signal, a touch signal, and / or a temperature signal are obtained, it is determined that the button has been normally triggered. In some embodiments, based on step S201, when a press trigger signal, a touch signal, and at least one of a temperature signal are obtained, it is determined that the button has been normally triggered, meaning that the button is manually triggered and therefore can normally trigger the corresponding function. However, when only one of the signals is obtained, it indicates that the object pressing the button may not be the user, or that the user has only touched the button without needing to operate it. Therefore, it can be determined that the button has been abnormally triggered. In this case, according to the determination result, the atomizing device does not execute the function corresponding to the button, thereby protecting the battery and preventing the atomizing device from starting incorrectly.

[0029] In other embodiments, the button can also be a touch button, and further, the trigger signal can be a touch trigger signal. For example, when a user touches the sensing surface corresponding to the button with their finger and executes step S10, a touch trigger signal of the button is obtained.

[0030] In some scenarios, touch buttons may also trigger touch signals without human intervention. Therefore, to further improve the accuracy of button trigger detection, a sensing signal is also acquired in step S10. Specifically, the sensing signal can be a temperature signal; that is, when a finger touches the button, the finger has a temperature, and the corresponding temperature signal can be obtained by sensing the temperature.

[0031] Furthermore, step S20 can be optimized as follows: when both the touch trigger signal and the temperature signal are received, it is determined that the button has been normally triggered. In some embodiments, based on step S20, when both the touch trigger signal and the temperature signal are received, it is determined that the button has been normally triggered, meaning that the button is manually triggered and therefore can normally trigger the corresponding function. However, when only one of the signals is received, it indicates that the object touching the button may not be the user, or that the user has only touched the button without actually operating it. Therefore, these situations can all indicate that the button has been abnormally triggered. In this case, according to the determination result, the atomizing device does not execute the function corresponding to the button, thereby protecting the battery and preventing the atomizing device from erroneously starting.

[0032] In some embodiments, the press button and the touch button may adopt the structure of press buttons and touch buttons in the prior art, which will not be described in detail here.

[0033] In some embodiments, the press trigger signal of the button can be triggered and acquired using the button's own mechanical structure.

[0034] In some embodiments, the touch signal of the pressed button and the touch trigger signal of the touch button can be acquired in a similar way, that is, by using capacitive touch sensing to identify the slight capacitance changes caused by human touch.

[0035] In some embodiments, the temperature signals of pressed and touched buttons can be achieved by setting a temperature sensor. Specifically, a temperature sensor can be set on the contact surface of the button or at a position very close to the contact surface of the button. When the user touches the button, the temperature sensor obtains the corresponding temperature signal. Furthermore, the temperature sensor can detect the object touching the button by using a thermistor or infrared radiation. When the sensed temperature is within the human body temperature range, a temperature signal is fed back.

[0036] In some embodiments, the button is configured to trigger the atomizing device to turn on or off. The atomizing device system has a low-power operation mode and a normal operation mode. The low-power operation mode is the default state of the atomizing device system (which can also be understood as standby mode, a state in which no atomization work is performed), while the normal operation mode is the working state in which the atomizing device performs atomization work. In this state, the atomizing device can atomize the stored liquid matrix to form an aerosol for the user to enjoy.

[0037] In some embodiments, the overall quiescent current of the atomizer is less than 10 μA in low-power operation mode. In normal operation mode, the operating current of the atomizer is between 1.5A and 15A.

[0038] In some embodiments, please refer to Figure 2 If step S20 determines whether a trigger signal and at least one sensing signal have been obtained, and if so, step S30 is executed, at which point the atomizing device performs the function triggered by the button, i.e., the atomizing device operates in normal working mode; otherwise, step S40 is executed, at which point the atomizing device maintains a low-power operating mode to reduce battery consumption. It is understandable that the trigger signal and sensing signal can determine whether the atomizing device has been manually used; when manually used, the atomizing device operates in normal working mode.

[0039] In some embodiments, step S20 further includes: if a trigger signal or sensing signal is received, and it is determined that the button has not been properly triggered, then the atomizing device system maintains a low-power operation mode. It is understood that the atomizing device is in a low-power operation mode by default. When a false touch is detected, the atomizing device can continue to maintain the low-power operation mode to reduce battery wear during abnormal operation.

[0040] Please refer to Figure 3This application also provides a control circuit for an atomizing device, including a main control chip MCU (Microcontroller Unit), a first circuit, and at least one second circuit. The first circuit includes a button SW1, which has at least one sensor A. One end of the first circuit is connected to the main control chip MCU to obtain a trigger signal from the button SW1. One end of the second circuit is connected to the sensor A, and the other end is connected to the main control chip MCU to obtain a sensing signal from the button SW1 via the sensor A. The main control chip MCU is configured to receive the trigger signal and the sensing signal, and execute the function triggered by the button SW1 based on the received result. The main control chip MCU, as the core processing unit, controls the operating mode of the atomizing device. Furthermore, when the button SW1 is triggered, it can send the trigger signal to the main control chip MCU via the first circuit. When the button SW1 is triggered, the sensor A obtains the sensing signal; if the sensor A obtains the sensing signal, it sends the sensing signal to the main control chip MCU via the second circuit.

[0041] In some embodiments, the main control chip (MCU) is configured to execute the function triggered by button SW1 when it receives a trigger signal and a sensing signal. With this setting, the main control chip (MCU) can determine that button SW1 is triggered normally, and therefore execute the function corresponding to button SW1, so that the atomizing device can start and perform atomization work normally.

[0042] Please refer to Figure 3 In some embodiments, button SW1 includes a first terminal 1 and a second terminal 2, with the first terminal 1 grounded. The first circuit also includes a first resistor R3, one end of which is connected to the battery of the atomizing device, and the other end of which is connected to a pin of the main control chip MCU and the second terminal 2 of button SW1. With this configuration, when button SW1 is not operated, the second terminal 2 of button SW1 is in a floating state, and the pin of the main control chip MCU is kept at a high level through the first resistor R3. When button SW1 is pressed, the second terminal 2 of button SW1 is grounded, and the level of the pin of the main control chip MCU goes low, generating a trigger signal.

[0043] Please refer to Figure 3In some embodiments, the main control chip (MCU) further includes output pins and input pins; the second circuit includes a second resistor R4, a third resistor R5, and a touch chip IC (Integrated Circuit) connected in series. One end of the second resistor R4 is connected to the output pin, one end of the touch chip IC is connected to the sensor A, and the input pin is connected between the second resistor R4 and the third resistor R5. The output pin of the MCU is used to output a trigger signal to the second circuit, and the input pin is used to receive and detect signals. The second resistor R4 and the third resistor R5 are connected in series to form a voltage divider network. The touch chip IC is connected between the sensor A and the voltage divider network to process the sensed signal, and the input pin is connected between the second resistor R4 and the third resistor R5 to monitor the level change at the voltage divider point.

[0044] Taking the button press as an example, when the button SW1 is stuck or accidentally pressed due to external force, only a trigger signal is generated, while the sensing signal is missing. At this time, the input pin detects the voltage divider level driven only by the trigger signal, and the main control chip MCU remains in a sleep state. When manually operated, the trigger signal and the sensing signal arrive synchronously. The input pin detects the voltage divider level driven by both signals, and the main control chip MCU activates to execute the function. Under this setting, the system can accurately detect the synchronization of the trigger signal and the sensing signal, thereby ensuring that the main control chip MCU is activated only when both signals are present simultaneously. This further reduces the probability of button SW1 being accidentally triggered, improves the reliability of button SW1, and also helps prevent abnormal power consumption of the atomizing device's battery, ensuring that the battery voltage of the atomizing device can be maintained within the normal operating range before use.

[0045] In some embodiments, the parameters of at least one of the first resistor R3, the second resistor R4, and the third resistor R5 are adjusted so that when the atomizing device is in a low-power operation mode, the overall static current of the atomizing device is less than 10μA.

[0046] In some embodiments, the sensor A includes a metal PAD.

[0047] In some embodiments, the sensor A and the touch chip IC can be connected via an FPC flexible flat cable.

[0048] In some embodiments, button SW1 is a press button, and the sensing signal includes at least one of a touch signal and a temperature signal. Specifically, one of the sensing signals and the trigger signal can be used together as a judgment condition, or the touch signal, temperature signal, and trigger signal can be used together as a judgment condition. The specific steps can be referred to the description of the foregoing embodiments, and will not be repeated here.

[0049] This application also provides an atomizing device that employs the control circuit described in the above embodiments. With this configuration, the atomizing device can utilize dual logic to determine whether a button press is accidental or intentional, thereby preventing abnormal battery drain caused by accidental button presses, further improving the battery life stability of the atomizing device, and extending its service life.
