Abstract
Description
Technical Field
[0001] This application relates to the field of atomizing device technology, specifically to a method for preventing self-starting of an atomizing device and an atomizing device that prevents self-starting. Background Technology
[0002] Existing atomizing devices generally use airflow sensors to detect inhalation as the signal to activate the device. Alternatively, they use airflow sensors to adjust power based on changes in air pressure. While the airflow sensor detects pressure changes and the controller activates the device accordingly, in situations where there are no inhalation pressure changes, such as in air ducts, the control system may misinterpret the changes and automatically restart.
[0003] Furthermore, the diaphragm on the airflow sensor of the atomizing device is susceptible to self-starting due to external environmental factors such as e-liquid, condensate, solder balls, and flux. Self-starting can easily lead to device burn-out, posing a significant risk to the user's personal safety and property. Summary of the Invention
[0004] To address the aforementioned problems, the present invention aims to provide a method for preventing self-starting of an atomizing device and an atomizing device that prevents self-starting, thereby resolving the technical issues of existing atomizing devices' inability to completely eliminate the self-starting problem and the potential safety hazards to users' personal safety and property. The details are described below.
[0005] According to the first aspect, this embodiment provides a method for preventing self-starting of an atomizing device, comprising the following steps: establishing a status dataset of the atomizing device; receiving a trigger signal and trigger time from an airflow sensor, and retrieving historical sensor data records from the established status dataset based on the trigger time; determining whether the atomizing device was used by a user before the trigger time based on the sensor data in the retrieved historical sensor data records; and controlling the atomizing device to maintain a low-power mode and simultaneously prohibiting power output when it is determined that the device was not used by a user or the atomizing device is in a static state, so that the atomizing device is in a non-working state.
[0006] In one embodiment, the step of establishing the state dataset includes:
[0007] The timer unit periodically wakes up the main control unit;
[0008] After the main control unit is woken up, the main control unit reads and saves the sensor data records of the atomizing device for a first set time period, and the multiple sensor data records form a status dataset.
[0009] In practice, the sensor data recording includes vibration sensor data and airflow sensor data.
[0010] In one embodiment, determining that the device is not being used by a user, or determining that the atomizing device is in a static state, includes:
[0011] At the same time, no vibration sensor data or airflow sensor data was detected, indicating that the device was in a static state.
[0012] Or, if airflow sensor data is detected but vibration sensor data is not detected; if the airflow sensor data is less than the second threshold, it is determined to be in a static state.
[0013] Alternatively, if no vibration sensor data is detected, it is determined that the atomizing device is not being used by the user, and the main control unit shuts off the power output to keep the atomizing device from starting.
[0014] In one embodiment, the method of not being used by the user further includes the following steps:
[0015] When vibration sensor data is detected and the vibration sensor data is less than the first threshold, the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0016] If vibration sensor data and airflow sensor data are detected simultaneously, and the vibration sensor data is less than the first threshold and the airflow sensor data is less than the second threshold, then the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0017] According to the second aspect, this embodiment provides an anti-self-starting atomizing device, including a main control unit, which is connected to an atomizing power output circuit, an airflow sensor, and a vibration sensor.
[0018] This main control unit is used to establish the status dataset of the atomizing device;
[0019] The main control unit is used to receive the trigger signal and trigger time from the airflow sensor, and retrieve historical sensor data records from the established status dataset based on the trigger time;
[0020] The main control unit is used to determine whether the atomizing device was used by the user before the triggering time based on the sensor data in the retrieved historical sensor data records;
[0021] The main control unit is used to control the atomization power output circuit to maintain a low power consumption mode and disable power output when it determines that the device is not in use or is in a static state, so that the atomization device is in a non-working state.
[0022] In one embodiment, the main control unit of the anti-self-starting atomizing device further includes a timer unit, wherein,
[0023] The timer unit is used to periodically wake up the main control unit;
[0024] After the main control unit is woken up, it is used to read and save the sensor data records of the atomizing device for a first set time period, and the multiple sensor data records form a status dataset.
[0025] In one embodiment, the sensor data recording in the anti-self-starting atomizing device includes vibration sensor data and airflow sensor data.
[0026] In one embodiment, the static state includes a static state when no vibration sensor data and airflow sensor data are detected simultaneously; or a static state when airflow sensor data is detected but no vibration sensor data is detected; or a static state when the airflow sensor data is less than a second threshold.
[0027] In practice, the following are also examples of products not used by users:
[0028] When vibration sensor data is detected and the vibration sensor data is less than the first threshold, the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0029] If vibration sensor data and airflow sensor data are detected simultaneously, and the vibration sensor data is less than the first threshold and the airflow sensor data is less than the second threshold, then the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0030] Compared with the prior art, the present invention has the following beneficial effects:
[0031] In this invention, the main control unit periodically collects the output status data of the vibration sensor to detect and determine the usage status of the smoking device. Before selecting the corresponding power output after receiving the trigger signal from the airflow sensor, it first completes the usage status judgment of the smoking device. Based on the different usage status of the smoking device, it determines whether to start the output power, thereby further protecting the smoking device from self-starting and minimizing the probability of self-starting, making the use more stable and safe.
[0032] In addition, the timer unit can periodically wake up the main control unit. Whether the atomizing device is in use or not, the main control unit will start a self-test at set time intervals to ensure that the atomizing device has not started on its own and to keep the system from outputting power in the event of an accidental start-up, thus enhancing safety.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.
[0040] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0041] Please refer to this as well. Figure 1 as well as Figure 2 , Figure 1 The diagram shown is a schematic diagram of the circuit module of the anti-self-starting atomizing device in this embodiment. Figure 2 The diagram shown is a schematic of the anti-auto-start software module in this embodiment.
[0042] In one embodiment, the atomizing device includes a housing and a cartridge. A mouthpiece is located at one end of the housing. A rechargeable battery, such as battery cell 20, is installed within the housing.
[0043] The anti-self-starting atomizing device has a control circuit board inside its housing. This control circuit board includes a controller, also known as a main control unit 10. The main control unit 10 is electrically connected to a battery cell 20, which is electrically connected to a charging management unit 21. The charging management unit 21 is connected to an external power source via a charging interface 22. The charging interface 22 can be a Type-C interface, a Mini-USB interface, or another low-voltage power interface.
[0044] The main control unit 10 is also electrically connected to the atomization power output circuit 20, the airflow sensor 40, the vibration sensor 50, the indicator unit 60, and the timer unit 70.
[0045] The airflow sensor 40 is located in the mouthpiece of the atomizing device, and the vibration sensor 50 is located between the rechargeable battery and the cartridge.
[0046] In this embodiment, the main control unit 10 writes an anti-self-starting control program; please refer to [reference needed]. Figure 2 The main control unit 10 includes an anti-self-starting software module, which includes a status data acquisition unit 16, a status judgment unit 17, and an anti-self-starting unit 18.
[0047] The status data acquisition unit 16 is used to periodically acquire the output status data of the vibration sensor 50. The status judgment unit 17 integrates data from other sensors to detect and judge the usage status of the smoking device. After receiving a trigger signal from the airflow sensor, such as the trigger signal from the airflow sensor 40, the status judgment unit 17 first completes the usage status judgment of the smoking device before selecting the corresponding power. The anti-self-starting unit 18 determines whether to start the output power according to the different usage statuses of the smoking device to further protect the smoking device from self-starting.
[0048] In this embodiment, before outputting power, the main control unit 10 first determines whether the vibration sensor 50 is vibrating or moving, and whether the airflow sensor 40 is transmitting airflow data for inhalation. A first threshold is set for the vibration sensor 50, and a second threshold is set for the airflow sensor 40. If movement is detected and exceeds the threshold, it indicates that the atomizing device is functioning normally and can output power. If the detected sensor data is below the threshold, the atomizing device is identified as not being used by the user or is in a static state, and will not output power regardless of whether inhalation is performed.
[0049] The main control unit 10 completes the acquisition of status datasets and determines the usage status of smoking devices according to the written control program.
[0050] The timer unit 70 is used to periodically wake up the main control unit 10. After the main control unit is woken up, the main control unit 10 is used to read and save the sensor data records of the smoking device for a first set duration, and multiple sensor data records form a status dataset.
[0051] The main control unit 10 receives the trigger signal and trigger time from the airflow sensor and retrieves historical sensor data records from the established status dataset based on the trigger time. The main control unit 10 determines whether the device was used by the user before the trigger time based on the sensor data in the retrieved historical sensor data records. If the main control unit 10 determines that the device was not used by the user or is in a static state, it shuts off the atomization power output circuit to prevent the device from starting.
[0052] In this embodiment, the sensor data recording includes vibration sensor data and airflow sensor data.
[0053] In this embodiment, the static state is defined as:
[0054] At the same time, no vibration sensor data or airflow sensor data was detected, indicating that the device was in a static state.
[0055] Or, if airflow sensor data is detected but vibration sensor data is not detected, the system is judged to be in a static state when the airflow sensor data is less than the second threshold.
[0056] In this embodiment, the definition that is not used by the user includes:
[0057] If no vibration sensor data is detected, it is determined that the atomizing device is not being used by the user, and the main control unit shuts off the power output to keep the atomizing device from starting.
[0058] When vibration sensor data is detected and the vibration sensor data is less than a first threshold, the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0059] If vibration sensor data and airflow sensor data are detected simultaneously, and the vibration sensor data is less than the first threshold and the airflow sensor data is less than the second threshold, then the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0060] In this embodiment, whether the device is being used by the user is determined by whether the atomizing device vibrates or moves, specifically by the output state of the vibration sensor 50. If no vibration sensor data is detected, it is determined that the atomizing device is not vibrating or moving, and the main control unit 10 keeps the atomizing device off by shutting down the atomizing power output circuit 30. If vibration sensor data is detected, or both vibration sensor data and airflow sensor data are detected simultaneously, and the data is below a judgment threshold, the main control unit shuts down the output power to keep the atomizing device off. If the data is above the judgment threshold, it is determined that the atomizing device is vibrating or moving, and the main control unit 10 controls the atomizing power output circuit 30 to output power to start the atomizing device.
[0061] Please refer to this as well. Figure 3 as well as Figure 4 The method for preventing self-starting of the atomizing device in this embodiment includes the following steps: Step S100: Establish a status dataset of the atomizing device.
[0062] The specific steps for establishing the state dataset include:
[0063] Step S110: Timer unit 70 periodically wakes up main control unit 10. When the atomizing device is in use or not, main control unit 10 will start self-test at set time intervals to determine that the atomizing device has not started on its own and to keep the system from outputting power in the event of an unexpected start.
[0064] Step S120: After the main control unit 10 is woken up, the main control unit 10 reads and saves the sensor data records of the smoking device for a first set duration, and multiple sensor data records form a status dataset. For example, after the main control unit 10 is woken up, it reads the output status of the vibration sensor 50, and the first set duration is set to 1 minute or 5 minutes. The main control unit 10 records and retains the vibration sensor 50 data for the most recent 1 minute or 5 minutes.
[0065] Step S200: The main control unit 10 receives the airflow sensor trigger signal and the trigger time, and retrieves historical sensor data records from the established status dataset based on the trigger time. These historical sensor data records are the most recent or second-preset time intervals of sensor data recorded by the main control unit 10. For example, the second-preset time interval is 1 minute or 5 minutes backward. When the airflow sensor is triggered, the main control unit 10 retrieves vibration sensor data from the established status dataset 1 minute or 5 minutes backward to determine whether the smoking device has vibrated or moved.
[0066] Multiple sensor data logs can be set depending on the specific judgment requirements and level of detail. In this embodiment, the sensor data logs include vibration sensor data and airflow sensor data.
[0067] In this embodiment, the static state is defined as:
[0068] At the same time, no vibration sensor data or airflow sensor data was detected, indicating that the device was in a static state.
[0069] Or, if airflow sensor data is detected but vibration sensor data is not detected, the system is judged to be in a static state when the airflow sensor data is less than the second threshold.
[0070] In this embodiment, the definition that is not used by the user includes:
[0071] If no vibration sensor data is detected, it is determined that the atomizing device is not being used by the user, and the main control unit shuts off the power output to keep the atomizing device from starting.
[0072] When vibration sensor data is detected and the vibration sensor data is less than a first threshold, the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0073] If vibration sensor data and airflow sensor data are detected simultaneously, and the vibration sensor data is less than the first threshold and the airflow sensor data is less than the second threshold, then the vibration or movement of the atomizing device is determined to be unused by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0074] Step S300: The main control unit 10 determines whether the smoking device was used by the user before the triggering time based on the sensor data retrieved from the historical sensor data records. This includes whether the device was used by the user or not.
[0075] Step S400: When the main control unit 10 determines that the device is not in use by the user or is in a static state, it controls the atomization power output circuit 30 to maintain a low power consumption mode and disables power output, so that the atomizing device is in a non-working state.
[0076] Please refer to Figure 5 The atomizing device in a static state includes:
[0077] B1: No vibration sensor data or airflow sensor data was detected at the same time, indicating that the system is in a static state.
[0078] B2: When airflow sensor data is detected but vibration sensor data is not detected; and the airflow sensor data is less than the second threshold.
[0079] The situations in which the product is not used by users include:
[0080] B3: No vibration sensor data used by the atomizing device was detected.
[0081] B4: When vibration sensor data is detected and the vibration sensor data is less than the first threshold, it is determined that the vibration or movement of the atomizing device is considered as not being used by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0082] B5: When vibration sensor data and airflow sensor data are detected simultaneously, and the vibration sensor data is less than the first threshold and the airflow sensor data is less than the second threshold, it is determined that the vibration or movement of the atomizing device is not used by the user, and the main control unit shuts down the output power to keep the atomizing device from starting.
[0083] Step S500: When the main control unit 10 determines that the device is being used by a user, it controls the output power to start the smoking device. When vibration sensor data or both vibration sensor data and airflow sensor data are detected, it is determined that the smoking device is vibrating or moving, and the main control unit controls the output power to start the smoking device.
[0084] The scenarios in which this is used by users include:
[0085] A1; Vibration sensor data was detected, and the vibration sensor data is higher than the first threshold.
[0086] A2; Simultaneously, vibration sensor data and airflow sensor data are detected, and the vibration sensor data is higher than the first threshold, while the airflow sensor data is higher than the second threshold.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. In the above embodiments, the connection relationships mentioned can be direct connections, and in some cases, indirect connections, such as those involving switches or relays. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
