All directional indications in the embodiments of this application (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship, movement, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0027] This application provides an atomizing device. Figure 1 、 Figure 2 The atomizing device 100 may include an atomizing assembly 10 and a control assembly 20. The atomizing assembly 10 stores an atomizing matrix, which can be atomized to generate an aerosol when heated. The atomizing assembly 10 is electrically connected to the control assembly 20, and the control assembly 20 can control the operation of the atomizing assembly 10. For example, the control assembly 20 can control the electrical connection between the atomizing assembly 10 and the control assembly 20 according to the user's puffing action, thereby controlling the atomizing assembly 10 to heat the atomizing matrix to generate an aerosol or stop heating. The atomizing assembly 10 and the control assembly 20 can be fixedly connected or detachably connected, such as a snap-on connection, a magnetic connection, or a threaded connection. When the atomizing assembly 10 and the control assembly 20 are detachably connected, if the remaining amount of atomizing matrix in the atomizing assembly 10 is less than a preset value, the user can conveniently separate the atomizing assembly 10 from the control assembly 20, and the atomizing device 100 can continue to be used after replacing the atomizing assembly 10, so that the control assembly 20 can be used multiple times, which helps reduce the user's usage costs.

[0028] See also Figure 2 、 Figure 3 The atomization assembly 10 includes a nozzle 11, an atomization core 14, and a liquid storage tank 12. The liquid storage tank 12 is used to store the atomization matrix. The atomization matrix in the liquid storage tank 12 can be transferred to the atomization core 14, and the atomization core 14 is used to heat the atomization matrix to generate an aerosol. The atomization core 14 can be installed in the liquid storage tank 12. The nozzle 11 is connected to one end of the liquid storage tank 12, and the nozzle 11 is used to contact the user's lips for the user to perform a suction operation. The nozzle 11 is connected to the atomization core 14, and the aerosol is output through the nozzle 11.

[0029] Please continue reading Figure 2 、 Figure 3The atomizing assembly 10 further includes a lip touch sensor 15, which is mounted on the suction nozzle 11. The lip touch sensor 15 is configured to generate a sensing signal based on the contact between the suction nozzle 11 and the user's lips. The atomizing device 100 can control the working parameters of the atomizing core 14 when heating the atomizing matrix based on the sensing signal. Exemplarily, a microcontroller unit (MCU) is provided on the control circuit board 23. The microcontroller unit receives the sensing signal and controls the working parameters of the atomizing core 14 when heating the atomizing matrix based on the sensing signal. With such a configuration, the user can adjust the working parameters of the atomizing core 14 when heating the atomizing matrix while inhaling. The adjustment feedback is synchronized with the adjustment operation, the user can obtain the adjustment feedback in a timely manner, and the control of the atomizing device 100 is more convenient.

[0030] In one embodiment, if Figure 2 、 Figure 3 As shown, the control assembly 20 may include a battery 21, an airflow sensor 22, and a control circuit board 23. The battery 21 is electrically connected to the control circuit board 23, and the battery 21 is used to provide electrical energy for the atomizer device 100 during operation. The airflow sensor 22, the atomizer core 14, and the lip touch sensor 15 are electrically connected to the control circuit board 23, and the airflow sensor 22 is used to control the heating state of the atomizer core 14. The airflow sensor 22 can control the electrical connection between the atomizer core 14 and the battery 21 based on the user's puffing action, thereby controlling the heating state of the atomizer core 14. Specifically, when the user inhales, the airflow sensor 22 senses the change in airflow, and the airflow sensor 22 controls the connection between the atomizer core 14 and the battery 21, so that the atomizer core 14 can heat the atomization matrix to generate aerosol; when the user stops inhaling, the airflow sensor 22 does not sense the change in airflow within a preset time period, and the airflow sensor 22 controls the atomizer core 14 to disconnect from the battery 21, and the atomizer core 14 stops heating.

[0031] In one embodiment, the operating parameters include one of heating power, heating temperature, or heating mode. The heating power affects the amount of smoke. The lip touch sensor 15 is provided with an adjustable operating parameter including the heating power, so that the user can select the appropriate amount of smoke by adjusting the heating power. The heating temperature affects the taste of the aerosol. A heating temperature that is too high may cause the atomized matrix to char and produce a burnt taste. A temperature that is too low may cause the atomized matrix to not be fully atomized, affecting the puffing experience. The lip touch sensor 15 is provided with an adjustable operating parameter including the heating temperature, so that the user can select the appropriate heating temperature according to different types of atomized matrix to obtain a better taste. The heating mode may include a constant voltage or constant current heating mode with a stable output voltage or current; or, when the atomizer core 14 includes multiple heating components, the heating mode may include an independent heating mode or a combined heating mode for the heating components. The lip touch sensor 15 is provided with an adjustable operating parameter including the heating mode, so that the user can select the corresponding heating mode according to their needs to obtain a different puffing experience.

[0032] The lip contact sensor 15 can be mounted on the outer wall of the nozzle 11. For example, the lip contact sensor 15 can be a pressure sensor. When the nozzle 11 contacts the user's lips, the lip contact sensor 15 generates a sensing signal based on the pressure changes caused by the contact between the nozzle 11 and the user's lips. For example, the adjustable operating parameters of the lip contact sensor 15 include heating power. If the user desires a larger amount of vapor, the contact pressure between the lips and the nozzle 11 can be increased, thereby adjusting the heating power to a high power setting. If the user desires a smaller amount of vapor, the contact pressure between the lips and the nozzle 11 can be reduced, thereby adjusting the heating power to a low power setting.

[0033] See also Figure 3 In one embodiment, the lip touch sensor 15 includes a sensing portion 151, which is disposed on the inner wall of the nozzle 11. The sensing portion 151 generates a change in capacitance based on contact between the nozzle 11 and the user's lips, and the lip touch sensor 15 can generate a sensing signal based on the capacitance change. Specifically, the sensing portion 151 can serve as the plate of a capacitor. When the user's lips come into contact with the nozzle 11, the dielectric constant of the capacitor changes, thereby causing a capacitance change. The lip touch sensor 15 can generate a sensing signal based on the capacitance change. Placing the sensing portion 151 on the inner wall of the nozzle 11 can prevent the sensing portion 151 from affecting the appearance of the nozzle 11. In addition, the capacitance change detection circuit is simple and reliable, which can reduce costs.

[0034] The flow direction of the aerosol in the nozzle 11 is taken as the height direction. For example, the height direction can be Figure 3The sensing portion 151 may be in the shape of a long strip extending in the height direction. When the user's lips touch the mouthpiece 11, the user can control the length of the sensing portion 151 at the user's mouth to change the capacitance value of the capacitor. The lip contact sensor 15 may generate a sensing signal based on the capacitance change, thereby changing the operating parameters of the atomizer core 14 when heating the atomized substrate.

[0035] The operating parameters can be adjusted continuously and steplessly. In one embodiment, the sensing portion 151 extends in the height direction, and the dimensions of the sensing portion 151 remain constant in the vertical direction. That is, the sensing portion 151 has a constant cross-section in the height direction. When the user's lips come into contact with the mouthpiece 11, the change in the length of the sensing portion 151 at the user's mouth can continuously change the capacitance value of the capacitor. The lip contact sensor 15 can generate a sensing signal based on the capacitance change, thereby continuously adjusting the operating parameters when the atomizer core 14 heats the atomized substrate.

[0036] The adjustment mode of the working parameters can also be discrete gear adjustment. In one embodiment, Figure 4 As shown, the sensing portion 151 extends in height, and in the vertical height direction, the size of the sensing portion 151 changes in a step-like manner. The number of steps in the sensing portion 151 can be two, three, or more, and accordingly, the operating parameters can be adjusted in two, three, or more levels. The step-like size change of the sensing portion 151 allows the operating parameters to have multiple preset adjustment levels, which can reduce the difficulty of user selection.

[0037] See also Figure 5 、 Figure 6 In one embodiment, the sensing portion 151 includes a plurality of sub-sensing portions 153, each of which is arranged at intervals on the inner wall of the nozzle 11. Each sub-sensing portion 153 generates a capacitance change based on the contact between the nozzle 11 and the user's lips. The lip touch sensor 15 can generate a sensing signal based on the number of sub-sensing portions 153 that generate capacitance changes. The electrical connection between the sub-sensing portions 153 can be in series or in parallel. When the number of sub-sensing portions 153 that generate capacitance changes is different, the capacitance value formed by the combination of the sub-sensing portions 153 is also different, thereby producing different sensing signals. The number of sub-sensing portions 153 can be two, three or more, and accordingly, the number of adjustable gears of the working parameters is two, three or more. The sensing portion 151 is provided with a plurality of sub-sensing portions 153, so that the working parameters have multiple preset adjustment gears, which can reduce the difficulty of selection for the user.

[0038] In one embodiment, if Figure 5As shown, each sub-sensing portion 153 extends in the height direction, and the extension dimensions of each sub-sensing portion 153 are different from each other. The sub-sensing portions 153 are arranged at intervals in the vertical height direction. In this arrangement, when the user's lips come into contact with the mouthpiece 11, due to the different extension dimensions of each sub-sensing portion 153, the number of sub-sensing portions 153 located in the user's mouth will also vary depending on the length of the mouthpiece 11 located in the user's mouth. This can change the capacitance value of the capacitor and adjust the operating parameters of the atomizer core 14 when heating the atomized matrix according to the preset gear.

[0039] See also Figure 6 In one embodiment, each sub-sensing portion 153 extends vertically and is spaced apart in the height direction. With this arrangement, when the user's lips come into contact with the mouthpiece 11, the sub-sensing portions 153 are spaced apart in the height direction. Depending on the length of the mouthpiece 11 at the user's mouth, the number of sub-sensing portions 153 located at the user's mouth also varies, thereby varying the capacitance of the capacitor and adjusting the operating parameters of the atomizer core 14 when heating the atomized substrate to a preset level.

[0040] Multiple sub-sensing parts 153 can be set on one side of the inner wall of the nozzle 11. In this case, the lip touch sensor 15 forms a single-pole capacitor, and the other "plate" can be a grounded conductive plane or the surrounding environment (such as a metal shell, the earth).

[0041] The plurality of sub-sensing portions 153 may also be disposed on opposite sides of the inner wall of the nozzle 11. Figure 7As shown, the lip touch sensor 15 includes a substrate 152 arranged in a vertical direction. The sensing portion 151 includes multiple first sub-sensing portions 153A and multiple second sub-sensing portions 153B. The multiple first sub-sensing portions 153A are connected to one side of the substrate 152 in the vertical direction, and the multiple second sub-sensing portions 153B are connected to the other side of the substrate 152 in the vertical direction. The multiple first sub-sensing portions 153A and the multiple second sub-sensing portions 153B are connected to each other in the vertical direction. The substrate 152 connects the multiple first sub-sensing portions 153A and the multiple second sub-sensing portions 153B into an integrated whole, thus ensuring a good overall integrity of the lip touch sensor 15 and facilitating assembly of the lip touch sensor 15. The substrate 152 can be a circuit board. In one embodiment, the substrate 152 is provided with an integrated circuit for detecting capacitance changes. The substrate 152 can generate a sensing signal based on the capacitance change of the sensing portion 151. In another embodiment, the substrate 152 or the sensing portion 151 is electrically connected to the control circuit board 23. The microcontroller unit on the control circuit board 23 generates the sensing signal based on the capacitance change of the sensing portion 151. In some embodiments, the nozzle 11 is a detachable module, the lip touch sensor 15 is integrated in the nozzle, the substrate 152 is arranged at the bottom of the nozzle 11, and is provided with electrical contacts for electrically connecting to the control component 20. When the lip touch sensor 15 fails, the lip touch sensor 15 can be replaced by replacing the nozzle 11. Compared with the method in which the sensor is arranged inside the atomization device 100, it is easier to replace the nozzle 11 module.

[0042] In the height direction, the extension dimension of each second sub-sensing portion 153B is the same as the extension dimension of the corresponding first sub-sensing portion 153A. With this arrangement, multiple sub-sensing portions 153 are respectively arranged on opposite sides of the inner wall of the nozzle 11. The first sub-sensing portion 153A and the second sub-sensing portion 153B can be connected to the positive and negative poles of the circuit, respectively, thereby forming a bipolar plate capacitor. Compared to a unipolar plate capacitor formed by multiple sub-sensing portions 153 being arranged on one side, the capacitance value is larger and the accuracy is higher, which can improve the sensitivity of the lip touch sensor 15.

[0043] For example, Figure 7 As shown, the lip touch sensor 15 is provided with three sensing parts 151, each sensing part 151 includes a first sub-sensing part 153A and a second sub-sensing part 153B, and the lengths of the three parts decrease in the height direction; in one embodiment, each sensing part 151 constitutes a part of the lip touch sensor 15, that is, Figure 7The three sensing portions 151, medium, long, medium, and short, each constitute a lip touch sensor 15. Each lip touch sensor 15 can independently emit a sensing signal based on the sensing portion 151 sensing a user's touch at a corresponding position on the mouthpiece 11. Different functions can be set for each of the three sensing portions 151. For example, the outermost, or longest, sensing portion 151 is always the first to be sensed. It can be understood that when a user's lips are around the mouthpiece 11, if they want to touch the positions on the mouthpiece 11 corresponding to the medium and short sensing portions 151, they will inevitably touch the longest sensing portion 151. Furthermore, in one embodiment, the airflow sensor 22 can be omitted. When the longest sensing portion 151 senses user contact, the atomizer device 100 activates the atomizer assembly 10 based on the sensing signal and heats it at a predetermined first operating parameter. When both the medium and long sensing portions 151 sense user contact, the atomizer device 100 activates the atomizer assembly 10 based on both sensing signals and heats it at a predetermined second operating parameter.

[0044] Of course, in other embodiments, the long, medium and short sensing parts 151 together constitute a part of a lip touch sensor 15, and the three constitute three capacitors in parallel or series. The circuit part of the lip touch sensor 15 can output different sensing signals according to the change values ​​of the three capacitors.

[0045] See also Figure 1 In one embodiment, the atomization device 100 includes an indicator 24, which is electrically connected to the lip contact sensor 15, and the indicator 24 is used to indicate the current value of the working parameter. The indicator 24 can be set in the control component 20, or it can be set in the atomization component 10. The indicator 24 can be an indicator light, and the indicator light can emit lights of different colors to indicate the current value of the working parameter. For example, when the user's lips touch the mouthpiece 11 to change the heating power of the atomization core 14, the indicator 24 can emit three different colors of light, red, yellow or blue, to indicate that the current value of the heating power is high power, medium power or low power.

[0046] In one embodiment, if Figure 3 As shown, the atomizer assembly 10 includes a lip contact mark 16, which is provided on the mouthpiece 11. The lip contact mark 16 is used to display the size of the mouthpiece 11 in the user's mouth when the mouthpiece 11 contacts the user's lips. The lip contact mark 16 can be a color mark or a scale mark, or it can be a protrusion or groove on the outer wall of the mouthpiece 11. For example, the mouthpiece 11 has different colors along the height direction to display the length of the mouthpiece 11 in the user's mouth when the mouthpiece 11 contacts the user's lips. The length of the mouthpiece 11 in the user's mouth corresponds one-to-one to the preset gear position, so that the user can determine the gear position to be adjusted by color, thereby facilitating use.

[0047] See also Figure 1、 Figure 3 In one embodiment, the atomizing device 100 further includes a housing assembly 30, and the atomizing assembly 10 and the control assembly 20 are mounted on the housing assembly 30. The housing assembly 30 may include a plurality of sub-housings to enclose a space for accommodating the atomizing assembly 10 and the control assembly 20.

[0048] The atomized matrix can be stored in the liquid storage bin 12 in the form of a liquid, or can be stored with the aid of a storage medium. For example, a liquid storage member 13 is provided in the liquid storage bin 12, such as Figure 3 As shown, the liquid storage component 13 is filled in the liquid storage tank 12, and the liquid storage component 13 is wrapped around the atomization core 14. The liquid storage component 13 is a porous medium, such as fiber cotton. The liquid storage component 13 can absorb the atomization matrix, thereby storing the atomization matrix in the liquid storage tank 12.

[0049] In one embodiment, if Figure 3 As shown, the atomizer core 14 includes a heating element 141, a liquid guide 142 and an atomizer tube 143. The liquid guide 142 is used to transfer the atomized matrix to the heating element 141. The heating element 141 is used to generate electricity and heat. The heating element 141 heats the atomized matrix to atomize it. Exemplarily, the liquid guide 142 is a cotton liquid guide, which is wrapped around the outer periphery of the heating element 141. The liquid guide 142 is at least partially accommodated in the atomizer tube 143, so that the heating element 141, the liquid guide 142 and the atomizer tube 143 form a relatively independent module, which is then assembled to the liquid storage tank 12 through the atomizer tube 143 to realize the modular assembly of the atomizer core 14, which can improve production efficiency.
