[0006] In some embodiments, the step of driving the atomizing core of the atomizing device to operate based on data calculation results specifically includes: Determine whether the data calculation result meets the preset conditions. If so, drive the atomizing core of the atomizing device to work according to the data calculation result. The preset conditions are: the hand coverage area value S_hand ≥ the minimum coverage area threshold S_th, and the effective inhalation flow rate Q ≥ the minimum inhalation threshold Q_th.

[0007] In some embodiments, the step of determining whether the data calculation result meets the preset conditions includes: Determine whether the data calculation result meets the preset conditions. If so, obtain the de-shaking time and determine whether it reaches the de-shaking time threshold. If it does, drive the atomizing core of the atomizing device to work.

[0008] This application also provides an atomizing device, which includes: The housing has a grip area and an air intake channel. The grip area is equipped with a touch sensor, and the air intake channel is equipped with an inhalation sensor. The touch sensor can be used to sense hand coverage area data, and the inhalation sensor can be used to collect inhalation data. The controller is used to receive hand coverage area data and / or inhalation data, and drive the atomizing core of the atomizing device to work based on the data calculation results.

[0009] In some embodiments, the touch sensor is a multi-point capacitive touch sensing electrode array; and / or the air intake sensor is a MEMS flow sensor or a differential pressure sensor.

[0010] In some embodiments, a multi-point capacitive touch sensing electrode array is disposed on one side of the housing to sense the coverage area and contour of the user's palm and fingers when holding the device to obtain hand coverage area data; a MEMS flow sensor or differential pressure sensor is disposed inside the air intake channel.

[0014] The implementation of this invention has the following beneficial effects: This application uses hand coverage data and inhalation data to identify the normal grip and inhalation action logic of adults. Children, due to differences in hand size, grip method, and breathing strength, cannot trigger the device to work, raising the threshold for child lock operation. Compared to ordinary child locks, it is much more difficult for children to accidentally break the lock, thus preventing accidental operation by children at the source. At the same time, adult users do not need to manually lock and unlock, making it convenient to use and preventing accidental activation, thus balancing safety and user experience.

[0017] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0019] This application provides a control method for the atomizing device, see [link to relevant documentation]. Figure 1 The methods include: Step 101: Obtain hand coverage area data and inhalation data.

[0020] Among them, the hand coverage area data is used to characterize the area of ​​the atomizer obstructed by the user's hand when holding the atomizer, and the inhalation data is used to characterize the airflow intensity and duration of the user's current inhalation. The target mist output range is determined based on the obtained hand coverage area data, and the actual mist output power of the atomizer is adjusted based on the inhalation data so that the actual mist output falls within the determined target mist output range, thus completing the power adjustment for this atomization process.

[0021] Hand coverage data is collected via a touch-sensitive array mounted on the atomizing device's housing. The number of touch-triggered sensors in the array is positively correlated with the hand coverage area. By counting the number of triggered sensors, the corresponding coverage area can be directly calculated. This calculation can be performed directly using a pre-defined table, eliminating the need for complex calculations and providing a quick result. Inhalation data is collected via a pressure sensor located in the atomizing device's airflow path. When the user begins to inhale, the air pressure within the path changes. The pressure sensor converts this change into an electrical signal, providing the corresponding airflow intensity. The duration of the pressure change is also recorded to determine the inhalation duration.

[0022] Step 102: Receive hand coverage area data and inhalation data, and drive the atomizing core of the atomizing device to work based on the data calculation results.

[0023] This application relies on dual-sensor features—hand coverage area data and inhalation data—to recognize the normal grip and inhalation action logic of adults. The calculation results based on these data serve as the basis for activating the atomizing core. Children, due to their incompatible hand size, grip method, and breathing intensity, cannot trigger the device. Furthermore, the dual-sensor system has higher requirements for the size of the user's hand and the intensity of their breathing, making it more difficult for children to accidentally bypass compared to ordinary child locks. This eliminates accidental operation by children at its source, balancing safety and user experience.

[0024] Furthermore, since the hand coverage area data and inhalation data are collected autonomously by the atomizing device, there is no need for the user to manually lock and unlock it, making it convenient to use.

[0025] After the atomization setting meets the above control method, a button can be added to control whether the atomizer core is driven to work. This has been described in related technologies and will not be elaborated on in the embodiments of this application. The atomization device control method of the embodiments of this application is used as a pre-control condition for driving the atomizer core to work.

[0026] In some embodiments, the atomizing device pre-stores a minimum coverage area threshold S_th and a minimum inhalation threshold Q_th for adult users; the hand coverage area data includes the hand coverage area value S_hand, and the inhalation data includes the effective inhalation flow rate Q.

[0027] By pre-setting minimum coverage area threshold and minimum inhalation threshold for adult users, the device can make dual judgments based on the hand coverage area value S_hand and the effective inhalation flow rate Q to accurately identify the normal usage status of the nebulizer by adult users, effectively preventing safety risks such as accidental touch or inhalation by children.

[0028] In some embodiments, the step of driving the atomizing core of the atomizing device to operate based on data calculation results specifically includes: Determine whether the data calculation results meet the preset conditions. If so, drive the atomizing core of the atomizing device to work according to the data calculation results.

[0029] The preset conditions are: the hand coverage area value S_hand ≥ the minimum coverage area threshold S_th, and the effective inspiratory flow rate Q ≥ the minimum inspiratory threshold Q_th.

[0030] The hand coverage area value S_hand is compared with the minimum coverage area threshold S_th to effectively prevent young children from activating the device due to small-area touching or unintentional pressing based on hand size conditions. Furthermore, the active inhalation condition is further compared with the effective inhalation flow rate Q and the minimum inhalation threshold Q_th to ensure that only users with sufficient breathing capacity can trigger nebulization, thereby eliminating the risk of children's misoperation.

[0031] Meanwhile, by comparing the hand coverage area with the minimum coverage threshold and the effective inhalation flow rate with the minimum inhalation threshold, the device holding status and user actions are determined. This can prevent accidental triggering, avoid damage to the device due to manual start-up, and ensure the normal use of the atomizing device.

[0032] When a user holds the atomizer, the system first compares the hand coverage area value S_hand with the minimum coverage area threshold S_th. If S_hand is less than S_th, the current holding position is deemed unsuitable for activation, and the atomizer remains in standby mode, not activating mist output. If S_hand is greater than or equal to S_th, the system proceeds to the inhalation verification stage, comparing the effective inhalation flow rate Q with the minimum inhalation threshold Q_th. If Q is less than Q_th, the inhalation trigger is deemed invalid, and the device remains in standby. Only when S_hand is not less than S_th and Q is not less than Q_th will the atomization process begin, and the actual mist output power will be adjusted according to the aforementioned logic. This threshold judgment logic effectively filters out accidental triggers caused by user touches or ineffective shallow breathing, avoiding unnecessary mist output waste. It also adapts to users with different holding habits, ensuring the robustness of the activation logic.

[0033] Furthermore, the minimum coverage area threshold S_th and the minimum inhalation threshold Q_th are set based on the thresholds of adult users, locking in two independent characteristics of the user: "large hands" and "strong suction". If a child lacks either of these characteristics, the operation will be stopped, ensuring safety and seamless operation.

[0034] In some embodiments, the step of determining whether the data calculation result meets the preset conditions includes: Determine whether the data calculation result meets the preset conditions. If so, obtain the de-shaking time and determine whether it reaches the de-shaking time threshold. If it does, drive the atomizing core of the atomizing device to work.

[0035] If the de-shake time threshold is not reached, the current standby state is maintained, and the atomizer coil is activated only after the de-shake conditions are met. This avoids data fluctuations caused by unstable grip or breathing, prevents repeated starting and stopping of the atomizer coil in a short period of time, reduces unnecessary power consumption, extends the lifespan of the atomizer coil, and further improves the accuracy of trigger judgment. If the judgment data calculation result does not meet the preset conditions, the atomizer device is kept in standby state and the activation operation is not performed.

[0036] In some embodiments, a secondary start signal is monitored during or after the atomizer core has stopped operating. If the signal is not received within a preset time threshold, it is determined that the user has completed the current operation, and the atomizer automatically returns to the locked state to prevent accidental triggering.

[0037] In this embodiment, the preset time threshold is 5 minutes.

[0038] If a valid secondary start signal is received, the atomizer core can be maintained or restarted directly without repeatedly triggering the child lock verification process, ensuring safety without affecting the user's continuous use experience.

[0039] In some embodiments, the secondary start signal includes a suction signal. If no suction signal is received within a preset time threshold, it is determined that the user has completed the current operation, and the atomizing device automatically returns to the locked state.

[0040] In some embodiments, the suction signal is determined by inspiratory flow rate data. If a signal with inspiratory flow rate data greater than or equal to the minimum inspiratory threshold is received within a preset time threshold, it is determined that a suction signal has been received within the preset time threshold. Otherwise, no suction signal has been received.

[0041] The atomizing device 100 provided in this application embodiment, such as Figure 2 As shown, it includes: The housing 1 is provided with a grip area 10 and an air intake channel 20. The grip area 10 is provided with a touch sensor 11 and the air intake channel is provided with an air intake sensor 21. The touch sensor 11 can be used to sense the hand coverage area data and the air intake sensor 21 can be used to collect air intake data. The controller 2 is used to receive hand coverage area data and / or inhalation data, and drive the atomizing core 3 of the atomizing device to work based on the data calculation results.

[0042] The housing design incorporates a grip area for the user and an airflow channel for air circulation. A touch sensor is integrated within the grip area to sensitively detect and acquire information about the area of ​​the user's hand in contact with the housing. Simultaneously, an inhalation sensor is placed in the airflow channel to collect airflow data during real-time inhalation. Furthermore, the atomizer includes a controller that receives hand coverage data from the touch sensor and / or inhalation flow data from the inhalation sensor. This controller then uses a built-in algorithm to comprehensively analyze and calculate this input information, ultimately precisely controlling and driving the activation and operation of the atomizer's core component—the atomizer coil—based on the processing results.

[0043] In some embodiments, the controller is a microcontroller. For example, a common microcontroller is generally an MCU (Microcontroller Unit), also known as a "single-chip microcomputer".

[0044] In some embodiments, the touch sensor is a multi-point capacitive touch sensing electrode array; and / or the air intake sensor is a MEMS flow sensor or a differential pressure sensor.

[0045] Employing a multi-point capacitive touch sensing electrode array as a touch sensor, it can accurately detect the contact coverage area. Combined with a MEMS flow sensor or differential pressure sensor to collect intake data, the dual detection scheme has high sensitivity, small size, and stable operation. It can reliably match the area and intake threshold determination requirements, improving the detection accuracy and safety of the equipment.

[0046] In some embodiments, a multi-point capacitive touch sensing electrode array is disposed on one side of the housing to sense the coverage area and contour of the user's palm and fingers when holding the device to obtain hand coverage area data; a MEMS flow sensor or differential pressure sensor is disposed inside the air intake channel.

[0047] Furthermore, by arranging the multi-point capacitive touch sensing electrode array on the grip side of the housing, data collection can be completed with the user's natural gripping action, eliminating the need for additional button structures. This simplifies the overall design and avoids the sticking and failure issues that occur with physical buttons after long-term use, further improving the structural reliability of the device.

[0048] In some embodiments, the minimum coverage area threshold S_th is the coverage area at which at least 3 electrodes are effectively triggered.

[0049] The device proposed in this invention comprises: a multi-point capacitive touch-sensitive electrode array (arranged in the grip area of ​​the atomizer housing), a MEMS flow sensor or differential pressure sensor (arranged within the air intake channel), a microcontroller (MCU), an atomizer drive circuit, and a power supply. The MCU pre-stores the minimum coverage area threshold S_th (e.g., the area corresponding to at least 3 electrodes being effectively triggered) and the minimum inhalation threshold Q_th for an adult user. During operation, the MCU continuously acquires the coverage area S_hand of the capacitive array and the hand force data F_grip from the grip force sensor. The atomizer power is only turned on when the logical judgment "S_hand≥S_thANDQ≥Q_th" is true and the de-jitter time is maintained; if either condition is not met, the device remains locked.

[0050] In some embodiments, five touch electrodes are arranged on the front and back of the atomizer housing, forming a large detection area; a flow sensor probe is installed in the airway equalization chamber. When an adult user holds the device, it naturally covers more than three electrodes, and when a deep inhalation meets Q_th, the device immediately unlocks and atomizes. For children, the palm area is limited, and even strong inhalation cannot meet the coverage requirements, or the airflow may be blocked due to insufficient inhalation in children with large hands (which is rare).
