[0025] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, the terms "first", "second", "third" and the like are only for the convenience of describing the technical solutions, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second", "third" and the like can explicitly or implicitly include one or more features.

[0026] As shown in Figure 1 In an embodiment, an atomization device is provided, which includes a main machine shell 61, a suction nozzle 51, a heating assembly 41, and a first sensing unit 11, a second sensing unit, a first processing unit 12, a second processing unit 22 and a control unit 30.

[0027] The suction nozzle 51 is arranged at one end of the main machine shell 61, and a user performs suction by holding the suction nozzle 51, and correspondingly, the user's upper and lower lips contact the opposite sides of the suction nozzle 51 to complete the suction action. The heating assembly 41 is arranged in the main machine shell 61, and after the heating assembly 41 is started, it heats the atomization substrate of the atomization device to form an aerosol for the user to suck. The process of a user using the atomization device is usually as follows: the user holds the main machine shell with his hand, puts the suction nozzle of the atomization device into his mouth, and then the user's upper and lower lips contact the opposite sides of the suction nozzle 51 to perform suction.

[0028] The first sensing unit 11 is arranged in the main machine shell 61, and is electrically connected with the first processing unit 12 to transmit the first sensing signal of the main machine shell 61 monitored. In this embodiment, the first sensing unit 11 generates a first sensing signal after the user contacts the main machine shell 61, and transmits it to the first processing unit 12. For example, in a common use scenario, the user holds the main machine shell 61 with his hand to generate a first sensing signal.

[0029] The second sensing unit is electrically connected with the second processing unit 22, and includes two second sub-sensing units 21. The second sub-sensing units 21 are respectively arranged on opposite sides of the suction nozzle 51, and respectively transmit the second sub-sensing signals of the monitored upper lip of the user and the side of the suction nozzle 51, and the lower lip and the other side of the suction nozzle 51. In this embodiment, the second sub-sensing units 21 are arranged on the inner wall of the suction nozzle 51, so as to avoid the interference of the external environment on the monitoring, and avoid the direct collision of external objects, and protect the sensing unit. In some embodiments, one second sub-sensing unit 21 is arranged on one side of the suction nozzle 51, and generates a second sub-sensing signal after the upper lip of the user contacts the side of the suction nozzle 51, and transmits the second sub-sensing signal to the second processing unit 22. Another second sub-sensing unit 21 is arranged on the other side of the suction nozzle 51, and generates another second sub-sensing signal after the lower lip of the user contacts the other side of the suction nozzle 51, and transmits the second sub-sensing signal to the second processing unit 22.

[0030] The first processing unit 12 is electrically connected with the control unit 30, and transmits the first sensing signal to the control unit 30 based on the obtained first sensing signal. In this embodiment, the first processing unit 12 can adopt an induction IC. The first processing unit 12 converts the first sensing signal into a digital signal, generates a corresponding first sensing signal, and transmits the first sensing signal to the control unit 30, so as to facilitate the identification of the control unit 30.

[0031] The second processing unit 22 is electrically connected with the control unit 30, and transmits the second sensing signal to the control unit 30 based on the obtained second sub-sensing signal. In this embodiment, the second processing unit 22 can adopt an induction IC. The second processing unit 22 converts the two second sub-sensing signals into digital signals, generates a corresponding second sensing signal, and transmits the second sensing signal to the control unit 30, so as to facilitate the identification of the control unit 30.

[0032] The control unit 30 includes a first storage module 31, a first timer module 32, and a first judgment module 33. The first storage module 31 records a first initial time triggered by the first sensing signal. The first timer module 32 activates the second sub-sensing unit 21 to detect the second sub-sensing signal within a first predetermined time after the first initial time. The input end of the first judgment module 33 respectively inputs the first sensing signal and the second sensing signal, and the output end is electrically connected with the heating assembly 41, and outputs the starting signal of the heating assembly 41.

[0033] In the embodiment, the first induction signal triggers the first storage module 31 to record the time of receiving the first induction signal as the first initial time. The first storage module is connected with the first timer module, the first timer module 32 reads the first initial time from the first storage module 31, activates the second sub-induction unit 21 to start detection at the first initial time, and counts to the first predetermined time, and closes the second sub-induction unit 21 after the first predetermined time. Wherein, the first predetermined time can be set according to actual needs. When the second sub-induction unit 21 detects the second sub-induction signal within the first predetermined time, the first judgment module 33 receives the second induction signal transmitted by the second processing unit 22, and then determines that the first induction signal and the second induction signal are received, and outputs the start signal of the heating assembly 41 to control the start of the heating assembly 41. When the second sub-induction unit 21 does not detect the second sub-induction signal within the first predetermined time, the first judgment module 33 does not output the start signal.

[0034] The microphone control in the related art is a single start condition, which is prone to false start. The present application combines the first induction unit 11 and the second sub-induction unit 21 to control the start of the heating assembly 41 according to the induction of the two sides of the host shell 61 and the suction nozzle 51, and effectively reduces the risk of false start of the heating assembly 41 through multiple start modules. At the same time, the second sub-induction unit 21 is activated after the first induction signal triggers, and the second sub-induction unit 21 is in an activated state only within the first predetermined time after the first initial time, which avoids being in an activated detection state all the time and saves power.

[0035] In one embodiment, as shown in Figure 2 , the first induction unit 11 is located at one end of the host shell 61 away from the suction nozzle 51, and the extension direction of the first induction unit 11 is parallel to the axial direction of the host shell 61. In another embodiment, as shown in Figure 3 , the first induction unit 11 is attached to the inner wall of the host shell 61 and extends along the circumference thereof. In one embodiment, the first induction unit 11 and the second sub-induction unit 21 are capacitive touch sensors. After the user touches the sensing area of the sensor on the host shell 61 or the suction nozzle 51, the sensor senses the change in capacitance and generates the first induction signal or the second sub-induction signal. The capacitive touch sensor is sensitive to touch action and has fast response speed, and can realize precise start control.

[0036] In one embodiment, as shown in Figure 4 , the atomization device further comprises a power supply unit 71 for power supply, and the power supply unit 71 is connected with the first processing unit 12, the second processing unit 22, the control unit 30 and the heating assembly 41 respectively. The power supply unit 71 is arranged in the host shell 61 and supplies power to the first processing unit 12, the second processing unit 22, the control unit 30 and the heating assembly 41 respectively.

[0037] In one embodiment, the atomizing device further includes a second switching unit K2 connected between the power supply unit 71 and the second processing unit 22. The control unit 30 is connected to the second switching unit K2, and after a first initial time, turns on the second switching unit K2 to connect the power supply unit 71 to supply power to the second processing unit 22, thereby activating the second sub-sensing unit 21.

[0038] When the atomizing device is off, the first sensing unit 11 remains active, the control unit 30 shuts down the second switch unit K2, the second processing unit 22 is de-energized, and the second sub-sensing unit 21 is de-energized and inactive. When the user holds the main unit housing 61, the first sensing unit 11 detects the first sensing signal. After receiving the first sensing signal, the control unit 30 opens the second switch unit K2, energizing the second processing unit 22 and activating the second sub-sensing unit 21, which then monitors the mouthpiece 51. The second switch unit K2 can be composed of a switching transistor, a triode, or other switches. This embodiment controls the energization and de-energization of the second processing unit 22 to activate or deactivate the second sub-sensing unit 21. When the second sub-sensing unit 21 is not needed, power supply to the second sub-sensing unit 21 and the second processing unit 22 is stopped, effectively saving energy in the power supply unit 71.

[0039] In one embodiment, the second processing unit 22 includes a second storage module, a second timer module, and a second judgment module. The second storage module records the second initial time triggered by the second sub-sensing signal of one of the second sub-sensing units 21. The second timer module activates another second sub-sensing unit 21 to detect another second sub-sensing signal within a second predetermined time after the second initial time. The second judgment module receives two second sub-sensing signals at its input terminal and outputs a second sensing signal to the control unit 30 at its output terminal.

[0040] like Figure 5 As shown, a third switch unit K3 is provided between one of the second sub-sensing units 21 and the second processing unit 22, while no third switch unit K3 is provided between the other second sub-sensing unit 21 and the second processing unit 22. When the second switch unit K2 is turned on, the second processing unit 22 is energized, and the second sub-sensing unit 21 without the third switch unit K3 is activated. When the third switch unit K3 is turned off, the corresponding second sub-sensing unit 21 is not activated. The second sub-sensing unit 21 without the third switch unit K3 detects the second sub-sensing signal at the nozzle 51 and transmits it to the second processing unit 22.

[0041] The second sub-sensing signal triggers the second storage module to record the time of receiving the second sub-sensing signal as a second initial time. The second timer module reads the second initial time from the second storage module, opens the third switch unit K3 at the second initial time to activate the other second sub-sensing unit 21 to start detection, and counts to a second predetermined time, and closes the third switch unit K3 after the second predetermined time. The second predetermined time is less than the first predetermined time, and the second predetermined time can be set according to actual needs. When the other second sub-sensing unit 21 detects the second sub-sensing signal within the second predetermined time, the second judgment module can receive the second sub-sensing signal transmitted thereby. The second judgment module judges that two second sub-sensing signals are received, and then outputs a second sensing signal to the control unit 30.

[0042] The scheme triggers another sub-sensing unit to monitor after one of the second sub-sensing units 21 monitors a signal, and does not require both second sub-sensing units 21 to be in an activated detection state at all times, thereby saving more power. In addition, since the upper and lower lips of the user contact the suction nozzle 51 during puffing, the second judgment module outputs a second sensing signal after receiving two second sub-sensing signals, thereby avoiding unilateral false triggering of the suction nozzle 51.

[0043] In an embodiment, the second processing unit 22 includes a second storage module and a comparator module. The second storage module records a second initial time corresponding to each second sub-sensing signal trigger, and the difference between the two second initial times is input to one end of the comparator module. The other input of the comparator module is the second predetermined time, and the output end of the comparator module outputs a second sensing signal to the control unit 30.

[0044] As shown in Figure 6 When the two sides of the suction nozzle 51 are contacted, the two second sub-sensing units 21 generate a second sub-sensing signal respectively. The second storage module records the receiving time of the two second sub-sensing signals as respective second initial times. When the difference between the two second initial times is within the second predetermined time, the comparator module outputs a second sensing signal to the control unit 30, otherwise it does not output a second sensing signal. The user's upper and lower lips contacting the two sides of the suction nozzle 51 have a certain time difference, so the two sub-sensing signals usually have a time difference. When the time difference between the two sub-sensing signals meets the second predetermined time, it is indicated that they are generated by the user's upper and lower lips contacting the two sides of the suction nozzle 51, and then a second sensing signal is output, thereby avoiding unilateral false triggering of the suction nozzle 51.

[0045] In other embodiments, as shown in Figure 7As shown, the second switch unit K2 between the power supply unit 71 and the second processing unit 22 can also be removed, and each second sub-sensing unit 21 is connected to the second processing unit 22 through a third switch unit K3. The control unit 30 is connected to the two third switch units K3, respectively, and opens the two third switch units K3 at the same time upon receiving the first sensing signal, thereby activating the two second sub-sensing units 21 to monitor. When the second initial time difference of the two second sub-sensing signals is within the second predetermined time, the comparator module outputs the second sensing signal to the control unit 30.

[0046] In an embodiment, the first judging module 33 includes an AND gate and a controller. The first input end of the AND gate is connected to the first processing unit 12, the second input end of the AND gate is connected to the second processing unit 22, the output end of the AND gate is connected to the controller, and the output end of the controller is electrically connected to the heat generating component 41. The AND gate activates the controller to send the start signal to the heat generating component 41 upon receiving the first sensing signal and the second sensing signal at the same time. The AND gate can be a diode AND gate, a transistor AND gate, a CMOS AND gate, or other types of AND gates. The controller can be an MCU. In some embodiments, the first storage module 31 and the first timer module 32 are arranged in the controller.

[0047] The user's posture for puffing is usually to hold the atomization device on one side and puff on the other side. After the second sub-sensing unit 21 is activated, the first sensing unit 11 and the second sub-sensing unit 21 can continuously monitor the sensing signal. The AND gate outputs a high level to the controller upon receiving the first sensing signal and the second sensing signal at the same time, and the controller in turn outputs the start signal to control the start of the heat generating component 41. This way avoids the case of accidental touch of the shell and the mouthpiece, and can reduce the possibility of false start.

[0048] It can be understood that, in the use process, the user's grip position can deviate from the sensing area of the second sub-sensing unit 21, and be in the non-sensing area on the main machine shell 61. In another embodiment, the first judging module 33 can not include an AND gate. The input end of the controller is connected to the first processing unit 12 and the second processing unit 22, respectively, and outputs the start signal upon receiving the second sensing signal within the first predetermined time after receiving the first sensing signal.

[0049] In an embodiment, as shown, Figure 8 The atomization device further includes a first switch unit K1 connected between the power supply unit 71 and the heat generating component 41. The control unit 30 is connected to the heat generating component 41 through the first switch unit K1, and outputs the start signal to open the first switch unit K1, thereby connecting the power supply unit 71 to supply power to the heat generating component 41 to start the heat generating component 41. When the start signal is not output, the first switch unit K1 is closed, and the heat generating component 41 is powered off.

[0050] In one embodiment, such as Figure 9 As shown, the first switching unit K1 includes a first switching transistor Q1 and a first resistor R1. The gate of the first switching transistor Q1 is connected to the control unit 30, the drain of the first switching transistor Q1 is connected to the heating component 41, and the source of the first switching transistor Q1 is connected to the power supply unit 71. The first resistor R1 is connected in parallel between the gate and source of the first switching transistor Q1. The first switching transistor is a PMOS transistor, and the first resistor can protect the first switching transistor and prevent it from malfunctioning.

[0051] In addition, the structures of the second switch unit K2 and the third switch unit K3 in the above embodiments can be referenced from the first switch unit K1.

[0052] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of this application should fall within the scope of the claims of this application.
