Description

CROSS REFERENCE TO RELATED APPLICATION

The present application is a continued application of an international application PCT/CN2025/138263, filed on Nov. 27, 2025, and claims priority to Chinese Patent Application No. 202422966628.9, filed on Nov. 29, 2024; the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present application relates to the technical field of atomization technology, and specifically to an atomizing device.

BACKGROUND

An atomizing device is a novel atomizing product that combines a heating element and a treated atomizing core. It heats the atomizing matrix in the atomizing core to a certain temperature by controlling the heating element, causing it to generate an aerosol upon heating, thereby meeting the requirements of the user.

Common atomizing device activation methods include an airflow detection type, a mechanical button type, and a combination of both. In the airflow detection type, when the user inhales, the internal airflow to the microphone or silicone microphone generates negative pressure. When the circuit connected the microphone or silicone microphone detects the negative pressure, the circuit converts the negative pressure into an electrical signal and transmits the electrical signal to the controller, thus activating the atomizing device. However, the electrical signals generated by the microphone or silicone microphone are easily interfered with by external factors. After repeated use, the condensed atomizing matrix in the airway may flow back to the microphone or silicone microphone, causing the microphone or silicone microphone to self-start or fail to start. The mechanical button type atomizing devices use pressure generated by pressing a button, the pressure is converted into an electrical signal to the controller to start the atomizing device. However, during transportation or use, vibration or pressure may cause false triggering, even leading to safety issues such as high temperatures and fires.

FIG. 1 is a schematic structural diagram of an atomizing device provided in one embodiment of the present application. As shown in FIG. 1, the atomizing device provided in this embodiment includes a housing 10, a nozzle 20, a controller 30, and an atomizing core 40.

In this embodiment, the housing 10 is enclosed to form a receiving cavity, in which the nozzle 20, the controller 30, and the atomizing core 40 are at least partially housed in the receiving cavity. The receiving cavity also has an air passage for airflow to flow through. The controller 30 is signal-connected to the atomizing core 40. When the atomizing device is in the operating state, the controller 30 controls the atomizing core 40 to heat a heating wire arranged inside the atomizing core 40 according to a preset heating curve or a preset output power curve. The atomizing matrix in the atomizing core 40 atomizes upon heating, forming an aerosol that is delivered to the user through the air passage.

The atomizing device includes a first sensing assembly 101 and a second sensing assembly 201. The first sensing assembly 101 is disposed on the housing 10 and generates a first sensing signal when touched by the user. The second sensing assembly 201 is disposed on the nozzle 20 and generates a second sensing signal when touched by the user.

The first sensing assembly 101 and the second sensing assembly 201 are electrically connected to the controller 30. When the atomizing device is in a powered-off state, when the user touches the first sensing assembly 101 and the second sensing assembly 201, a first sensing signal and a second sensing signal are respectively generated, which are transmitted to the controller 30 via a signal connection. The controller 30, upon receiving the first sensing signal and the second sensing signal, controls the atomizing device to enter the operating state. Furthermore, when the atomizing device is in the operating state, in response to the inhalation action of the user on the nozzle 20, it controls the atomizing coil 40 to perform atomization.

As one embodiment, when the atomizing device is in a powered-off state, the controller 30, in response to receiving the first sensing signal, controls the atomizing device to enter a standby state. And, after the atomizing device enters the standby state, upon receiving the second sensing signal within a first preset time period, it controls the atomizing device to enter an operating state.

It can be understood that, when the first sensing assembly 101 on the housing 10 is touched by the user, the controller 30 only receives the first sensing signal transmitted by the first sensing assembly 101. Based on this received signal, the controller 30 will control the atomizing device to enter a standby state from the powered-off state. At this time, the controller 30 does not receive the second sensing signal indicating that the user has touched the nozzle 20, and therefore will not control the atomizing core 40 to perform further atomization heating. However, after the atomizing device enters the standby state within a first preset time period, if the second sensing assembly 201 on the nozzle 20 is touched by the user, generating a second sensing signal transmitted to the controller 30, the controller 30 will then control the atomizing device to enter the operating state from the standby state. Subsequently, when the user inhales through the nozzle 20, the controller will further control the atomizing core 40 to perform heating and atomization.

In this embodiment, the atomizing device can only be activated and enter the operating state when both the the sensing assemblies on the nozzle 20 and the housing 10 are touched by the user, that is, when the controller 30 of the atomizing device receives the first sensing signal and the second sensing signal. If only one sensing signal is received, the atomizing device cannot be activated, effectively reducing the possibility of false triggering. It should be noted that the timing of the controller 30 receiving the first sensing signal and the second sensing signal can be simultaneous or sequential within a certain time period. The controller 30 can be configured to respond to the first sensing signal and the second sensing signal and control the atomizing device to enter the operating state under preset conditions.

As one implementation, the first sensing assembly 101 and the second sensing assembly 201 can be capacitive touch sensing elements or resistive touch sensing elements. The capacitive touch sensing element detects touch by sensing the capacitance change between the human body or other conductor and the sensor. When a human body or other conductor approaches or touches the sensor, it changes the capacitance on the sensor surface, thereby triggering the sensor to output. This allows for rapid and accurate detection of the touch location, supports multi-touch, has no mechanical structure, and is relatively less sensitive to surface contamination. It is generally more durable and stable than some mechanical touch technologies. Furthermore, capacitive touch sensors typically consume less power when not being touched, contributing to energy savings. Resistive touch sensing element detects touch by sensing the resistance change generated during a touch. When a human body or other conductor touches the sensor, it changes the internal resistance distribution, thereby triggering the sensor to output. The performance is stable, the atomizing device is less susceptible to environmental interference and is easy to manufacture, the cost is relatively lower, and most importantly, the atomizing device is unaffected by dust, oil, and moisture, and the adaptability is greater.

As another implementation, the first sensing assembly 101 and the second sensing assembly 201 can also be piezoresistive tactile sensing elements, photoelectric tactile sensing elements, or piezoelectric tactile sensing elements. Compared to touch sensing elements, tactile sensing elements are sensors that detect external tactile information such as pressure, vibration, and heat stimulation. Utilizing principles such as piezoresistive, piezoelectric, and photoelectric effects, to convert this external tactile information into electrical signals for transmission and processing. This provides richer tactile information, facilitating more precise operation and control; which typically possess high sensitivity and accuracy, accurately sensing changes in external tactile information. Some tactile sensing elements also exhibit good flexibility and durability, such that the tactile sensing elements are suitable for various complex environments and application scenarios.

As one implementation method, the housing 10 of the atomizing device is arranged with a first button. The first button can be any of a physical button, a virtual button, or a toggle button. The first button can be a power button for turning on the device, a button for adjusting parameters such as an output power, a voltage, or a temperature to control concentration, flavor, and temperature, or a function button for specific functions such as switching vapor modes, checking device state (e.g., battery level, cumulative inhalation actions), or accessing the settings interface.

In one embodiment, the first sensing assembly 101 is provided with at least one conductive sensing sheet; the conductive sensing sheet is embedded in the first button, when contacts the surface of the first button, the conductive sensing sheet is capable of sensing user contact. The conductive sensing sheet can be a metal sheet, such as a copper sheet, an aluminum sheet, or a nickel sheet; the conductive sensing sheet can also be a metal conductive wire, a metal mesh structure, etc. The shape or size of the conductive sensing sheet is not limited here. When the user touches the first button, the conductive sensing sheet can promptly acquire a sensing signal and transmit the sensing signal to the controller 30.

In another embodiment, the second sensing assembly 201 is also provided with at least one conductive sensing sheet. The conductive sensing sheet can be embedded in the upper or lower wall surface of the nozzle 20, or simultaneously disposed on both the upper and lower wall surfaces, which facilitates user contact sensing when the nozzle is inside the mouth of a user. The mouth of the user touches the area where the conductive sensing sheet is located when the mouth of the user contacts the nozzle, the conductive sensing sheet acquires a second sensing signal and feeds the second sensing signal back to the controller 30.

In summary, the atomizing device provided in the embodiment of the present application, by providing sensing assemblies at the housing and the nozzle of the the atomizing device, so that a first sensing signal and a second sensing signal are respectively generated when the sensing assemblies at the housing and the nozzle are touched by a user; and these signals are transmitted electrically to the controller of the atomizing device. When the atomizing device is in the powered-off state, the controller, in response to receiving the first sensing signal and the second sensing signal, controls the atomizing device to enter the operating state. Furthermore, in response to the inhalation action of the user at the nozzle, it controls the atomizing core within the atomizing device to atomize, outputting aerosol to the user. The controller of the atomizing device in the present application starts the atomizing device based on the sensing signal obtained by the sensing assembly, effectively avoiding the problems of false triggering or failure to start existing atomizing devices. This atomizing device no longer relies on a single control method for starting; the atomizing device only enters the operating state when both the sensing assemblies on the nozzle and the housing are touched by the user. This reduces false triggering caused by a single starting method, improving start-up reliability and safety. Simultaneously, the touch sensing start method facilitates user operation and provides a new user experience.

FIG. 2 is a schematic diagram of the structure of an atomizing device according to another embodiment of the present application. As shown in FIG. 2, the atomizing device provided in this embodiment, based on any of the above embodiments, further includes a display module 50 signal-connected to the controller 30.

When the atomizing device is in a operating state or a standby state, the controller 30 is also used to output state parameter information characterizing the current state of the atomizing device and transmit the state parameter information to the display module 50. The display module 50 displays the acquired state parameter information under the control of the controller 30. The state parameter information includes at least one of the followings: a current state, a current remaining oil level, a current remaining battery power, an output power in the operating state, and a charging state. The display module 50 includes a display screen and can be connected to the processor via a serial communication interface or a parallel communication interface to achieve data transmission and display and update of the state parameter information of the atomizing device.

As one implementation, the controller 30 can also respond to a first instruction input by the user, controlling the atomizing device to enter a menu selection mode and controlling the display module 50 to display menu selection items, thereby realizing human-computer interaction between the user and the atomizing device.

For human-computer interaction between the user and the atomizing device, when the first sensing assembly 101 is positioned on the first button, when the user touches and performs a first operation on the first button, the first sensing assembly 101 generates a first instruction based on the first operation of the user and transmits the first instruction to the controller 30. That is, the display module 50 and the first button enable human-computer interaction between the user and the atomizing device.

As one implementation, the display screen of the display module 50 can be a touchscreen. When the user touches the touchscreen and performs a second operation, the display module 50 generates a corresponding second instruction based on the second operation of the user and transmits the second instruction to the controller 30, thereby enabling human-computer interaction between the user and the atomizing device.

FIG. 3 is a schematic diagram of the structure of an atomizing device provided in another embodiment of the present application. As shown in FIG. 3, the atomizing device provided in this embodiment, based on any of the above embodiments, further includes a power output module 60 and a charging module 70 that are signal-connected to the controller 30.

In this embodiment, after the controller 30 responds to the received first sensing signal and second sensing signal and controls the atomizing device to enter the operating state, it then responds to the inhalation action of the user on the nozzle 20. At this time, the controller 30 also controls the power output module 60 to output the corresponding heating power to the atomizing core 40 according to a preset power output curve, controlling the atomizing core 40 to atomize. Simultaneously, the controller 30 acquires the real-time heating power output by the power output module 60 and outputs the current output power of the atomizing device to the display module 50 for display, so that the user can intuitively understand the current state and easily adjust the current state according to preferences.

In practice, the atomizing core 40 is provided with a heating element. Under the control of the controller 30, the heating element heats according to a preset heating curve. After being heated, the atomizing matrix in the atomizing core 40 atomizes to form an aerosol that is delivered to the user. The atomizing core 40 in the atomizing device can have multiple types or only one type. Different types of atomizing cores 40 have different heating and atomization temperatures, therefore different heating curves are used to heat different types of atomizing cores 40. Therefore, in practical applications, one or more heating curves are predetermined when the atomizing device leaves the factory. When the heating curve of the atomizing device is determined, designers need to consider a large amount data of user inhalation habit. When the heating element is selected, it is also determined the reference parameters of the heating element based on the preset heating curve to ensure that the expected temperature performance is achieved when controlling the heating element. The preset heating curve can be a temperature-time change curve based on a temperature-time relationship heating mode, a temperature-time change curve based on a temperature-number of inhalation relationship heating mode, or a power output curve based on a temperature-heating power relationship. By outputting different heating powers, the resistance of the heating element is controlled to achieve the expected temperature.

In this embodiment, the charging module 70 of the atomizing device is provided with a connection interface for connecting to an external power source. The controller 30 is used to control the charging module 70 to charge the battery in the atomizing device according to a preset charging strategy when it detects that the charging module 70 is connected to an external power source through the connection interface. Simultaneously, during the charging process of the charging module 70 by the external power supply, the controller 30 also outputs charging information, representing the charging state and parameters, obtained in real time from the charging module 70, to the display module 50 so that the user can understand the current battery level.

In summary, the atomizing device provided in this embodiment, while utilizing touch sensing to control the atomizing device to start, also transmits the acquired state parameter information representing the current state of the atomizing device to the display module 50 based on data transmission between the controller 30 and various functional modules. This information is then displayed on the display module 50, providing convenience for the user.
