Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to an atomization device. Background Technology

[0002] Current electronic atomizing devices typically employ a single activation method: either airflow sensor activation or lip-sensor activation. Airflow sensor activation triggers atomization by detecting changes in airflow, requiring continuous inhalation to maintain the airflow signal, which cannot meet the demands of a large, instantaneous aerosol burst. Lip-sensor activation directly triggers atomization by sensing lip contact with a contact sensor, but this carries the risk of accidental activation, and prolonged use may lead to a decrease in sensor sensitivity. Current atomizing devices lack dynamic optimization in their activation mode control, preventing users from freely switching modes according to usage scenarios, resulting in high power consumption or insufficient atomization efficiency. Utility Model Content

[0003] This application provides an atomizing device that allows users to freely switch between different activation modes according to usage scenarios.

[0004] In some embodiments, the atomizing device includes a housing, an atomizing component, an airflow sensor, a lip sensing component, and a mode switching component. The housing is connected to a mouthpiece. The atomizing component, disposed within the housing, is used to atomize an aerosol matrix. The airflow sensor, disposed within the housing and connected to the atomizing component, is used to sense changes in airflow pressure in an airflow-activated mode to activate the atomizing component. The lip sensing component, disposed on the mouthpiece and connected to the atomizing component, is used to sense contact between the user and the mouthpiece in a lip-sensing activated mode to activate the atomizing component. The mode switching component, connected to the airflow sensor and the lip sensing component, is used to switch between the airflow-activated mode and the lip-sensing activated mode.

[0005] In some embodiments, the lip sensing assembly includes a sensor that is attached to the surface of the mouthpiece, wherein the sensor is one of a capacitive sensor, a pressure sensor, an optical sensor, and an ultrasonic sensor.

[0006] In some embodiments, the lip sensing component further includes a sensing chip, which is connected to the sensing element and the atomizing component respectively. The sensing element is a capacitive sensor, and the inner surface of the mouthpiece is fitted with the surface of the capacitive sensor. At least a portion of the outer surface of the mouthpiece forms a sensing electrode to generate a sensing signal when a human body comes into contact with the sensing electrode. The sensing signal can be transmitted to the sensing chip through the sensing element.

[0007] In some embodiments, the mode switching component includes a control motherboard, which includes an instruction receiving unit and a data processing unit. The instruction receiving unit is used to receive operation signals input by the user. The data processing unit is electrically connected to the lip sensing component, the airflow sensor, and the atomizing component, and switches the current startup mode according to the operation signal.

[0008] In some embodiments, the atomizing device further includes a power supply component electrically connected to the control motherboard, the power supply component supplying power to the airflow sensor in the airflow activation mode and to the lip sensing component in the lip sensing activation mode.

[0009] In some embodiments, the data processing unit includes a dynamic power distribution module, which is used to adjust the output power of the power supply component; wherein, the output power of the power supply component in the airflow start mode is dynamically adjusted with the airflow, the output power of the power supply component in the lip-sensing start mode is fixed at the maximum output power, or the output power of the power supply component in the lip-sensing start mode gradually increases to the maximum output power over time.

[0010] In some embodiments, the mode switching component further includes a display screen disposed on the surface of the housing, the display screen being used to display a selection interface between the airflow activation mode and the lip-sensing activation mode.

[0011] In some embodiments, the instruction receiving unit includes a button disposed on the side wall of the housing, and an outwardly protruding operating portion is formed on the surface of the side wall; and / or, the instruction receiving unit includes a touch module integrated on the display screen, the touch module being used to sense the user's touch operation.

[0012] In some embodiments, the control motherboard is disposed along the length of the housing and fixedly connected to the display screen, and the control motherboard is connected to the sensing chip, the airflow sensor and the power supply component via wires.

[0013] In some embodiments, the housing is provided with an airflow channel communicating with the nozzle, and the airflow sensor is disposed in the airflow channel with its detection surface perpendicular to the airflow direction.

[0014] The atomizing device provided in this application integrates an airflow sensor and a lip sensor component, enabling it to offer different atomization efficiencies and activation methods under different activation modes. This effectively solves the problem of traditional atomizing devices having only one activation method and addresses the issue that a single trigger mode cannot meet the diverse usage needs of users. Through the mode switching component, users can select either the airflow activation mode or the lip sensor activation mode according to their needs and preferences, improving the product's applicability and user experience.

[0031] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the atomizing device in some embodiments of this application. Figure 2 yes Figure 1 An overall explosion diagram of the atomizing device in the embodiment. Figure 3 yes Figure 1 A cross-sectional schematic diagram of the atomizing device in the embodiment.

[0032] This application provides an atomizing device, including a housing 10, an airflow sensor 50, an atomizing component 20, a lip sensing component 30, and a mode switching component 40.

[0033] The housing 10 is made of high-temperature resistant plastic. A suction nozzle 70 is fixedly connected to one end of the housing 10. The outer surface of the suction nozzle 70 is arc-shaped to fit the user's lips. An airflow channel 15 communicating with the suction nozzle 70 is provided inside the housing 10.

[0034] The atomizing assembly 20 includes an atomizing core 21, an atomizing tube 23, and a liquid guiding component 22. At least a portion of the airflow channel 15 is defined by the atomizing tube 23. The atomizing core 21 is embedded within the atomizing tube 23, and the liquid guiding component 22 covers the outside of the atomizing core 21 for adsorbing the aerosol matrix. The atomizing core 21 is in contact with the liquid guiding component 22, and when energized, it heats the aerosol matrix, causing it to atomize into an inhalable aerosol.

[0035] An airflow sensor 50 is installed inside the housing 10, specifically within the airflow channel 15, and is connected to the atomizing assembly 20. In airflow activation mode, when the user inhales, the airflow sensor 50 detects a change in airflow pressure to activate the atomizing assembly 20. Specifically, the atomizing assembly 20 can be activated when the detected airflow pressure change exceeds a preset value.

[0036] A lip sensor assembly 30 is disposed on the mouthpiece 70 and connected to the atomizing assembly 20. In lip sensor activation mode, the lip sensor assembly 30 senses the user's contact with the mouthpiece 70 to activate the atomizing assembly 20. The lip sensor assembly 30 includes a sensing element 31, which is attached to the surface of the mouthpiece 70. For example, the sensing element 31 can be two capacitive sensors, which are characterized by high sensitivity and strong anti-interference. The inner surface of the mouthpiece 70 is fitted with the surface of the capacitive sensors, that is, the inner surface of the mouthpiece 70 matches the three-dimensional contour surface of the capacitive sensors, ensuring complete contact between the two. The two capacitive sensors form sensing electrodes on at least part of the outer surface of the mouthpiece 70, so that when the human body contacts the sensing electrodes, the human body capacitance can couple with the electrodes to form a circuit, thereby generating a sensing signal. The lip sensor assembly 30 also includes a sensing chip 32, which is used to process the sensing signal and trigger atomization. The sensing chip 32 is connected to the sensing element 31 and the atomizing component 20. When the user brings their lips close to or touches the mouthpiece 70, the capacitance between the lips and the sensing electrode changes. After the sensing element 31 detects this change, it transmits the sensing signal to the sensing chip 32 and the atomizing component 20 in sequence. The atomizing component 20 is activated to realize the atomization and inhalation of the aerosol.

[0037] Please see Figure 4 , Figure 4 yes Figure 1 A schematic diagram of the control motherboard of the atomizing device in this embodiment. The mode switching component 40 is connected to the airflow sensor 50 and the lip sensing component 30, and is used to switch between the airflow activation mode and the lip sensing activation mode. The mode switching component 40 includes a control motherboard 42, which includes an instruction receiving unit 421 and a data processing unit 422. The instruction receiving unit 421 is used to receive operation signals input by the user. For example, the instruction receiving unit 421 includes a button 41, which is disposed on the side wall of the housing 10, and has an outwardly protruding operating part formed on the surface of the side wall of the housing for convenient user operation.

[0038] The data processing unit 422 is electrically connected to the lip sensor component 30, the airflow sensor 50, and the atomizing component 20, and switches the current start-up mode according to the operation signal. The data processing unit 422 includes a processor. In airflow start-up mode, the processor acquires airflow change signals through the airflow sensor 50 and outputs control signals to the atomizing component 20. In lip sensor start-up mode, the processor acquires sensing signals through the lip sensor component 30 and outputs control signals to the atomizing component 20. For example, if the current mode is airflow start-up mode, pressing button 41 switches the atomizing device's operating state to lip sensor start-up mode and controls the relevant components to make corresponding adjustments, such as stopping power supply to the airflow sensor 50 and starting power supply to the lip sensor component 30.

[0039] It is understood that, in addition to being indirectly connected to the atomizing component 20 via the control motherboard 42 as described above, the airflow sensor 50 and the lip sensing component 30 can also be directly connected to the atomizing component 20 in other embodiments, so as to directly activate the atomizing component 20 in different startup modes.

[0040] The atomizing device provided in this application integrates an airflow sensor 50 and a lip-sensing component 30, enabling it to provide different atomization efficiencies and activation methods under different activation modes, effectively solving the problem of the single activation method in traditional atomizing devices. Through the mode switching component 40, users can choose between airflow activation mode or lip-sensing activation mode according to their needs and preferences, improving the product's applicability and user experience. For example, when a user wants to experience the sensation of inhaling a cigarette, they can switch to airflow activation mode, triggering the atomizing device to output aerosol through inhalation; or, when a user uses a high-powered atomizing device or does not want to inhale forcefully, they can switch to lip-sensing activation mode, where the user only needs to hold the mouthpiece of the atomizing device in their lips to trigger activation and output aerosol; or, if a user desires a lung-inhaling experience, i.e., a larger vapor volume, requiring low airway resistance, and low airway resistance makes it difficult for the airflow sensor 50 to activate, switching to lip-sensing activation mode eliminates the influence of airway resistance. Furthermore, in some embodiments, an airway / airflow switching component can be provided to set the ventilation volume, such as flow rate or velocity, thereby achieving a better personalized user experience in conjunction with the switching of the activation mode.

[0041] In other embodiments, the sensing element 31 may be a pressure sensor, an optical sensor, or an ultrasonic sensor, in addition to the capacitive sensor described in the above embodiments.

[0042] When the sensing element 31 is a pressure sensor, it is attached to the outer surface of the mouthpiece 70. When the user's lips touch the mouthpiece 70, the lips exert pressure on the surface of the mouthpiece 70. The pressure sensor senses this pressure change and converts the pressure signal into an electrical signal, i.e., a sensing signal. This sensing signal is transmitted to the sensing chip 32 through a connection line, and then from the sensing chip 32 to the atomizing assembly 20, activating the atomizing assembly 20. For example, when the user forcefully touches the mouthpiece 70, the pressure value detected by the pressure sensor exceeds a set threshold, triggering the transmission of the sensing signal, thereby activating the atomizing assembly 20.

[0043] When the sensor 31 is an optical sensor, an optical emitting and receiving device is provided on the surface of the mouthpiece 70. When the user's lips approach or touch the mouthpiece 70, they will block or reflect light. The optical sensor determines the user's contact status by detecting changes in light. For example, when the lips block the emitted light, the intensity of the light received by the optical sensor changes, generating a sensing signal. This signal is transmitted to the sensing chip 32 and the atomizing assembly 20, activating the atomizing assembly 20.

[0044] When the sensor 31 is an ultrasonic sensor, it emits ultrasonic signals into the surrounding space. When the user's lips approach the mouthpiece 70, the ultrasonic signal is reflected upon contact with the lips. The ultrasonic sensor receives the reflected signal and determines the distance and contact status between the lips and the mouthpiece 70 based on the signal's time delay and intensity changes. When the distance reaches a set value, the ultrasonic sensor generates a sensing signal, which is transmitted to the sensing chip 32 and the atomizing assembly 20, activating the atomizing assembly 20.

[0045] Please see Figure 2 and Figure 3 In some embodiments, the atomizing device further includes a power supply component 60, which is electrically connected to the control motherboard 42 and provides power to the entire atomizing device. In airflow start mode, the power supply component 60 powers the airflow sensor 50; in lip-sensing start mode, the power supply component 60 powers the lip-sensing component 30.

[0046] The data processing unit 422 includes a dynamic power distribution module, which can be a power control chip or a power conversion circuit, or other power management components or modules used to control power. The dynamic power distribution module is used to adjust the output power of the power supply component 60.

[0047] In the airflow-activated mode, the dynamic power distribution module dynamically adjusts its output power based on changes in airflow pressure. For example, when the user inhales forcefully and the airflow pressure changes significantly, the dynamic power distribution module controls the power supply component 60 to increase its output power, enabling the atomizing component 20 to atomize the aerosol matrix more quickly, meeting the user's inhalation needs. When the inhalation force is weak, the output power is reduced accordingly to save energy. For instance, in the airflow-activated mode, the output power ranges from 5W to 25W, and the dynamic power distribution module dynamically adjusts the output voltage based on the airflow change signal from the airflow sensor 50, achieving on-demand power supply.

[0048] In lip-sensor start-up mode, the dynamic power distribution module triggers maximum power output based on the sensing signal. When the sensing signal is detected, the dynamic power distribution module of the data processing unit 422 triggers the power supply component 60 to output maximum power, ensuring that the atomizing component 20 can start quickly and provide a good user experience. For example, in lip-sensor start-up mode, the dynamic power distribution module controls the output power to be fixed at 25W. Alternatively, the output power of the power supply component 60 in lip-sensor start-up mode gradually increases to the maximum output power over time. For example, if the maximum output power of the power supply component 60 is 25W, the dynamic power distribution module controls the power supply component 60 to reach 50% of the output power in the first second and 80% of the output power in the second second.

[0049] Optionally, the power supply component 60 has a built-in overcurrent protection chip that automatically cuts off the output when the current exceeds the threshold.

[0050] In this embodiment, the output power of the power supply component 60 is further optimized under different start-up modes, so that dynamic power adjustment can be achieved in the airflow start-up mode and a large amount of aerosol output can be provided instantaneously in the lip-sensing start-up mode. This is applicable to a variety of atomization scenarios and improves energy utilization efficiency and battery life.

[0051] Please continue reading. Figure 2 and Figure 3 In some embodiments, the mode switching component 40 includes a display screen 43, which is embedded in the surface of the housing 10 and is used to display a selection interface for the airflow start mode and the lip-sensor start mode, such as displaying icons and names of the two modes. The display screen 43 can also display a power indicator.

[0052] Optionally, the data processing unit 422 includes an update module for updating the current startup mode on the display screen 43 according to the operation signal. The update module includes a microcontroller that, upon receiving the operation signal, initiates a display driver to update the interface elements of the display screen 43. The update module may also include a memory, which can be non-volatile memory (NVM), used to store the current mode flag and synchronize it to the display screen 43, supporting automatic recovery of the last operating mode after power failure. For example, if the currently displayed mode is airflow startup mode, pressing button 41 will change the icons and text on the display screen 43 accordingly, indicating that the lip-sensing startup mode is selected. Simultaneously, the control motherboard 42 controls the power supply component 60 to stop supplying power to the airflow sensor 50 and start supplying power to the lip-sensing component 30, completing the mode switch. During use, the user can observe the mode selection interface on the display screen 43 at any time to understand the current startup mode. If a mode switch is needed, simply pressing button 41 is sufficient. This intuitive display and convenient operation greatly improve the user's ease of operation and experience with the atomizing device.

[0053] Optionally, the instruction receiving unit 421 includes a touch module for sensing user touch operations. The touch module can be a capacitive sensing layer or a resistive touch layer, and can be integrated onto the display area of ​​the display screen 43 using a surface coating process. It is understood that the atomizing device in this application can switch its activation mode via mechanical triggering, such as by using the button 41 mentioned above; or by switching the activation mode via touch interaction, such as by integrating a touch module on the display screen 43; or by combining mechanical triggering with touch interaction. This application does not impose specific limitations.

[0054] In some embodiments, the control motherboard 42 is arranged along the length of the housing 10 and fixedly connected to the display screen 43. The control motherboard 42 is connected to the sensing chip 32, the airflow sensor 50, and the power supply component 60 via wires. This layout ensures stable communication and collaborative operation between the various components, ensuring that the atomizing device can operate normally in different startup modes.

[0055] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A cross-sectional schematic diagram of the atomizing device in another section of the embodiment; Figure 6 yes Figure 1 A partial explosion diagram of the atomizing device in the embodiment. In some embodiments, the sensing chip 32 can be integrated onto the control motherboard 42 or the sensing chip 32 and the control motherboard 42 can be separate. For example, the housing 10 is provided with a chamber 11, a first seal 12 and a second seal 13, which together form a liquid storage cavity 14. The first seal 12 is located between the nozzle 70 and the second seal 13. The sensing chip 32 is disposed on the side of the first seal 12 away from the liquid storage cavity 14 to avoid damage to the sensing chip 32 due to the influence of the aerosol matrix in the liquid storage cavity 14. Two sensors 31 are provided, both of which are sheet-like structures. The two sensors 31 are fixedly welded to the sensing chip 32 to ensure signal transmission efficiency.

[0056] In some embodiments, the detection surface of the airflow sensor 50 is perpendicular to the airflow direction. It is understood that airflow changes occur when a user inhales. A perpendicular detection surface allows the airflow sensor 50 to more stably detect changes in airflow pressure, ensuring timely and accurate transmission of airflow change signals to the atomizing component 20 when the user inhales. This reduces the impact of airflow turbulence on the detection results, improves detection sensitivity and accuracy, and ultimately enables stable startup and operation of the atomizing component 20.

[0057] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
