Description

Technical Field

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

[0002] As a novel type of nicotine inhalation device, nebulizers typically use airflow sensors to detect the user's inhalation behavior, enabling automatic start-up and shutdown control. The airflow sensor converts changes in airflow into electrical signals, which are then identified by the control module to determine whether the user has inhaled. This solution is simple in structure, responds quickly, and has been widely applied in existing nebulizers.

[0003] However, in actual use, the airflow sensor is susceptible to interference from contamination. Especially after prolonged use or storage of the atomizer, condensate may flow back into the airflow sensor cavity, or poor sealing may cause e-liquid to leak into the sensor area, affecting the sensor's normal recognition. When the airflow sensor is contaminated with condensate or e-liquid, it may output a false signal resembling a vaping action, even if the user is not vaping, thus triggering the atomizer to start abnormally and causing it to automatically atomize when stationary.

[0004] To prevent the aforementioned false triggering, some existing technologies attempt to determine the effectiveness of the suction action using software algorithms. For example, setting a minimum effective inhalation time, analyzing signal amplitude and trends, or locking the atomizing device after a certain threshold of abnormal triggers. These solutions can reduce energy consumption and safety hazards caused by false triggering to some extent, but still suffer from issues such as response lag, limited recognition accuracy, and the impact of false locking on normal user operation. Therefore, since these solutions primarily rely on software recognition and control, they cannot fundamentally solve the problem of false recognition caused by contamination of the airflow sensor hardware, and the overall robustness and security of the system still need improvement.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] Please refer to Figure 1 This application provides an atomizing device 10, including a housing 110, a gas sensing module 120, an atomizing component 130, a power supply 140, and a control module 150.

[0042] In one embodiment, the outer shell 110 is the internal structure that encloses the atomizing device 10, and at least a portion of it is made of metal material and serves as a touch sensing area, capable of forming capacitive coupling with the user's skin to generate a touch signal.

[0043] In one embodiment, a gas sensing module 120 is disposed inside the atomizing device 10 and is used to detect whether the atomizing device 10 is performing a suction action. When the user inhales, a change in airflow or air pressure is detected, and a first driving signal is output through the output terminal of the gas sensing module 120. Preferably, the gas sensing module 120 can be a pressure sensor, an airflow switch, or a micro-heat flux sensor.

[0044] In one embodiment, the atomizing component 130 is used to heat the aerosol matrix after being powered on, forming an aerosol for the user to inhale. The atomizing component 130 can be disposed inside the housing 110, integrated with the power supply 140 and the control module 150 in the same housing 110 to form an integrated atomizing device 10, or it can be as follows: Figure 2 In another structural configuration shown, the atomizing component 130 is disposed outside the housing 110 and is detachably connected to the housing 110 via a plug-in or snap-on structure. It is understood that the aerosol matrix can be an atomizing liquid or a solid matrix, such as a matrix containing tobacco or non-tobacco plants.

[0045] It should be noted that when the atomizing component 130 is located outside the housing 110, it can achieve a reliable electrical connection with the control module 150 through electrode contacts or magnetic conductive structure, and its mechanical structure ensures a stable connection and facilitates replacement or maintenance.

[0046] In one embodiment, the power supply 140 may be a built-in lithium battery used to provide power to the atomizing component 130. The power supply 140 is electrically connected to the atomizing component 130 through the control module 150, and the power supply 140 and the atomizing component 130 are only turned on when the control module 150 detects a valid drive signal.

[0047] Please refer to Figure 3 In one embodiment, a control module 150 is disposed between a power supply 140 and an atomizing component 130 and is used to control the working state of the atomizing component 130. The control module 150 includes a touch detection circuit 151 and a logic circuit 152.

[0048] In one embodiment, the input terminal of the touch detection circuit 151 is connected to the metal area of ​​the housing 110. When the user's finger or palm touches the metal area, the touch detection circuit 151 detects the touch signal and generates a second driving signal accordingly. The second driving signal is output from the output terminal of the touch detection circuit 151 to the logic circuit 152.

[0049] In one embodiment, the first input terminal of the logic circuit 152 is connected to the output terminal of the gas sensing module 120 to receive a first driving signal; the second input terminal of the logic circuit 152 is connected to the output terminal of the touch detection circuit 151 to receive a second driving signal; the output terminal of the logic circuit 152 is connected to the atomizing component 130, and is used to connect the power supply 140 and the atomizing component 130 when both the first input terminal and the second input terminal receive the corresponding driving signals, so that the power supply 140 supplies power to the atomizing component 130 and drives the atomizing component 130 to work.

[0050] It should be noted that the atomizing device 10 provided in this application uses the gas sensing module 120 and the touch detection circuit 151 as dual triggering conditions. Atomization is only activated when the user touches the atomizing device 10 and performs an inhalation action, avoiding activation due to accidental touch or non-inhalation scenarios, reducing the risk of accidental touch, and improving user safety. The metal area in the housing 110 serves as a natural grip contact point, realizing interactive control between the human body and the atomizing device 10 without adding extra structural complexity.

[0051] Please refer to Figure 4 In one embodiment, the touch detection circuit 151 includes a touch chip 1511, which includes a signal input terminal and a signal output terminal. The signal input terminal of the touch chip 1511 is connected to a metal area on the housing 110 and is used to sense the capacitance change caused by human touch behavior. The signal output terminal of the touch chip 1511 is connected to a logic circuit 152 in the control module 150 and is used to output a corresponding second driving signal when a touch signal is detected.

[0052] In one embodiment, the touch chip 1511 may be a VM8601D chip. The VM8601D chip is a low-power, high-sensitivity capacitive touch detection chip with a built-in touch sampling circuit, noise suppression filtering module, and steady-state output capability. The VM8601D chip can determine the change in coupling capacitance when the user's skin contacts the metal area through capacitive sensing technology and quickly output a valid touch signal. When used in conjunction with the logic circuit 152, the second drive signal output by the VM8601D chip will serve as one of the necessary conditions for activation. Only after simultaneously detecting the first drive signal (inhalation action) of the gas sensing module 120 and the second drive signal (user grip) of the touch detection circuit 151 will the atomizing component 130 be allowed to operate, forming a dual trigger protection.

[0053] Please refer to Figure 5 In one embodiment, in order to improve the anti-interference ability and stability of the touch signal generated by human touch behavior, the touch detection circuit 151 further includes a first filtering module 1512. The first end of the first filtering module 1512 is connected to the input end of the touch detection circuit 151, and the second end of the first filtering module 1512 is connected to the signal input end of the touch chip 1511.

[0054] In one embodiment, the first filtering module 1512 may include an RC low-pass filter circuit, a TVS transient suppression transistor, or an electrostatic discharge protection device to suppress the impact of sudden signals such as high-frequency noise, electromagnetic interference (EMI), or human electrostatic discharge (ESD) on touch recognition.

[0055] Please refer to Figure 6The first filter module 1512 in this application includes a capacitor C1 and a resistor R1. The first end of the resistor R1 is connected to the input terminal of the first filter module 1512, the second end of the resistor R1 is connected to the first end of the capacitor C1, the second end of the capacitor C1 is connected to the reference ground, and the first end of the capacitor C1 is also connected to the output terminal of the first filter module 1512.

[0056] Please refer to Figure 6 In one embodiment, the touch detection circuit 151 further includes a capacitor C4, and the touch chip 1511 further includes a power supply terminal, which is connected to a reference ground through the capacitor C4.

[0057] Please refer to Figure 7 In one embodiment, to improve the wiring flexibility and structural compatibility of the touch detection circuit 151, the touch detection circuit 151 further includes an external wiring harness 1513. Specifically, the input terminal of the touch detection circuit 151 is connected to the first terminal of the external wiring harness 1513, and the second terminal of the external wiring harness 1513 is connected to the metal area on the housing 110 of the atomizing device 10, for transmitting the touch signal generated when the user touches the metal area to the touch detection circuit 151.

[0058] In one embodiment, the external wiring harness 1513 may be a flexible wire (such as a ribbon cable, a small wiring harness such as UL1571), which facilitates flexible wiring in situations where space is limited or the structure is separated, in order to adapt to the atomizing device 10 provided in this application.

[0059] In one embodiment, to ensure connection reliability, the second end of the external wiring harness 1513 is electrically connected to the metal region via a conductive structure 1514. The conductive structure 1514 can employ any one or more combinations of the following: a spring-loaded conductive sheet, conductive foam, gold-plated contacts, screw connecting pieces, and solder joints. The spring-loaded conductive sheet can be tightly pressed against the metal region after assembly to ensure continuous conductivity; the conductive foam can compress the conductive material to form a flexible conductive path at the structural contact point; the gold-plated contacts and screw connecting pieces are used for long-term secure connection with high conductivity stability; and the solder joints can be permanently encapsulated.

[0060] Please refer to Figure 8 In one embodiment, the logic circuit 152 includes an AND gate 1521 for implementing dual judgment logic control of inhalation and touch behavior. The AND gate 1521 includes a first input, a second input, and an output. The first input of the AND gate 1521 is connected to the output of the gas sensing module 120 to receive a first drive signal indicating inhalation behavior. The second input of the AND gate 1521 is connected to the output of the touch detection circuit 151 to receive a second drive signal indicating that the user is touching a metal area. The output of the AND gate 1521 is connected to the output of the logic circuit 152 to control whether the atomizing component 130 is connected to the power supply 140.

[0061] In one embodiment, the AND gate 1521 can be implemented using a digital logic chip (such as the 74HC08 series), a microcontroller's internal logic module, or an AND gate 1521 functional circuit composed of discrete components.

[0062] Please refer to Figure 6 In one embodiment, the logic circuit 152 further includes resistor R2, capacitor C2, and resistor R3 for signal processing and level stabilization. Specifically, the first input terminal of AND gate 1521 is connected to the output terminal of gas sensing module 120, and the second input terminal of AND gate 1521 is connected to the output terminal of touch detection circuit 151. To enhance anti-interference capability and prevent false triggering, the output terminal of touch detection circuit 151 is first connected to the second input terminal of AND gate 1521 through current-limiting resistor R2. To ensure stable power supply to AND gate 1521, the first terminal of capacitor C2 is connected to the power supply terminal of AND gate 1521, and the second terminal is connected to reference ground, forming a power supply filtering circuit. The output terminal of AND gate 1521 is connected to the first terminal of resistor R3, and the second terminal of resistor R3 is connected to the output terminal of logic circuit 152, thereby providing current-limiting protection for the output signal and improving the interface compatibility of subsequent drive or control module 150.

[0063] Please refer to Figure 9 In one embodiment, the gas sensing module 120 includes a pressure sensing chip 121 and a second filtering module 122. The pressure sensing chip 121 is used to sense the pressure changes generated when the atomizing device 10 has a suction action in real time, and it includes a voltage terminal and an output terminal. To ensure the stability and anti-interference capability of the pressure sensing signal, the second filtering module 122 is disposed in the power supply path of the pressure sensing chip 121.

[0064] Please refer to Figure 6 In one embodiment, the second filtering module 122 includes a capacitor C3 and a resistor R4 to form an RC filter network. The first terminal of resistor R4 is connected to the power supply voltage to provide operating power; the second terminal of resistor R4 is connected to the voltage terminal of the pressure sensing chip 121 and also to the first terminal of capacitor C3; the second terminal of capacitor C3 is connected to reference ground, thereby forming a low-pass filter circuit to effectively suppress high-frequency noise on the power supply side and improve the reliability of the pressure signal. The output terminal of the pressure sensing chip 121 is connected to the output terminal of the gas sensing module 120 to output the collected pressure signal.

[0065] The atomizing device 10 provided in this application, by setting an AND gate 1521 in the logic circuit 152, ensures that the atomizing device 10 only outputs a start signal when it simultaneously detects the first driving signal (inhalation action) and the second driving signal (user grip), thereby effectively avoiding the problem of false triggering under a single condition and improving the accuracy and safety of judgment. Furthermore, both the touch detection circuit 151 and the air pressure sensing module adopt an electrical filtering structure, using low-pass filtering to suppress signal noise and improve response stability, ensuring stable operation of the circuit in complex environments and facilitating the subsequent logic circuit 152 to obtain clean and effective signal input.
