Technical Field

[0001] This application relates to the technical field of atomization devices, and particularly relates to an atomization device. Background Art

[0002] The atomization device is powered by a battery and requires extremely low standby power consumption. When the atomization device works, the microcontroller (MCU) needs to wake up from the sleep state to the working state, and after suction, it needs to enter the low-power sleep state from the working state. During the long-term use of the atomization device, the MCU may not be able to wake up or freeze due to software design defects or external electrostatic discharge (ESD) events, resulting in the abnormal operation of the atomization device. That is, currently, when an abnormal situation such as the MCU crashing occurs in the atomization device, the MCU cannot be restored to normal operation in a timely manner.

[0003] In addition, in the related art, the MCU can be restored by adding a reset button in the atomization device. However, adding a reset button in the atomization device has a greater impact on the internal structure space of the atomization device and is not easy to operate. Summary of the Utility Model

[0004] In view of this, the present utility model aims to at least solve one of the problems in the related art to some extent. For this reason, the purpose of this application is to provide an atomization device.

[0012] In some embodiments, the power supply is a USB interface power supply.

[0014] In some embodiments, when the logic control unit is not connected to the power supply, the reset unit can reset the microcontroller normally, and the logic control unit, the level conversion unit, and the reset unit are in an inoperative state.

[0025] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0026] Please refer to Figure 1 , the present application provides an atomization device. The atomization device includes a microcontroller reset circuit 100, a microcontroller MCU, and a heating element assembly. The microcontroller MCU is respectively connected to the heating element assembly and the microcontroller reset circuit 100, and the microcontroller MCU controls the heating process of the heating element assembly. The microcontroller MCU includes a monitoring pin WDI and a reset pin NRST. The microcontroller reset circuit 100 includes a logic control unit 10, a level conversion unit 20, a reset unit 30, and a power supply 40.

[0027] The first input terminal 11 of the logic control unit 10 is connected to the monitoring pin WDI, the second input terminal 12 of the logic control unit 10 is connected to the power supply 40, and the output terminal 13 of the logic control unit 10 is connected to the input terminal 21 of the level conversion unit 20. The power supply 40 is used to supply power to the logic control unit 10, such as Figure 2 as shown, the power supply 40 can supply V BUS with a voltage of 5V to the logic control unit 10.

[0028] The output terminal 22 of the level conversion unit 20 is connected to the first terminal 31 of the reset unit 30, the second terminal 32 of the reset unit 30 is connected to the reset pin NRST, and the third terminal 33 of the reset unit 30 is grounded.

[0029] After the logic control unit 10 is powered on, if no pulse signal is received from the monitoring pin WDI within a preset time, an initial reset signal is output to the level conversion unit 20.

[0030] Among them, the preset time can be, for example, 2S, 3S, 3.1S, 3.2S, 3.3S, 3.4S, 3.5S, 3.6S, 3.7S or 4S, and there is no limit here.

[0031] The level conversion unit 20 converts the initial reset signal into an identifiable reset signal, and the reset unit 30 receives the identifiable reset signal to control the reset of the microcontroller MCU.

[0032] Specifically, in some embodiments, after the logic control unit 10 is powered on, if no pulse signal is received from the monitoring pin WDI within a preset time, it is determined that the microcontroller MCU is in an abnormal state, and the logic control unit 10 generates an initial reset signal.

[0033] In detail, the microcontroller reset circuit 100 of the present application can, when the microcontroller MCU is in an abnormal state such as crashing, if the logic control unit 10 does not receive a pulse signal from the monitoring pin WDI of the microcontroller MCU within a preset time, it is determined that the microcontroller MCU is in an abnormal state. For example, when the abnormal state is that the microcontroller MCU crashes, a Universal Serial Bus (USB) interface can be set in the logic control unit 10, and a charging cable is inserted through this USB interface and connected to the power supply 40, so that the logic control unit 10 can output an initial reset signal to the level conversion unit 20. Among them, the USB interface can be, for example, Figure 1 the interface formed by the first terminal 151 in the power-on controller 15 in

[0034] After the logic control unit 10 is connected to the power supply 40, the microcontroller reset circuit 100 can specifically be as Figure 2The circuit diagram shown. As Figure 2 shown, a unidirectional transistor D1 can also be provided on the connection circuit between the microcontroller MCU and the logic control unit 10 in the microcontroller reset circuit 100 of the present application. The unidirectional transistor D1 can achieve controlled rectification, that is, it allows current to pass through from one direction under specific conditions, similar to a controllable rectifier diode, so as to ensure that the pulse signal output by the WDI pin of the microcontroller MCU can be unidirectionally input into the logic control unit 10, and the WDI pin of the microcontroller MCU will not receive the electrical signal sent by the logic control unit 10, which can avoid interfering with the normal operation of the microcontroller MCU.

[0035] The level conversion unit 20 then converts the initial reset signal into a recognizable reset signal. After the reset unit 30 receives the recognizable reset signal, it then performs a hardware reset on the microcontroller MCU, enabling the microcontroller MCU to return to its normal state without the need to operate with a dedicated tool, which is convenient and fast.

[0036] That is to say, the level conversion unit 20 can convert an electrical signal that cannot be directly recognized by the reset unit 30 into a reset signal that can be recognized by the reset unit 30, so that the reset unit 30 can accurately and timely control the hardware reset of the microcontroller MCU according to the recognizable reset signal, thereby controlling the microcontroller MCU to return from an abnormal state to a normal working state.

[0037] In this way, in the microcontroller reset circuit 100 of the present application, since the logic control unit 10 is connected to the power supply 40, the logic control unit 10 can be kept in the powered-on state. When the microcontroller MCU is abnormal, the logic control unit 10 can output an initial reset signal according to the abnormal state of the microcontroller MCU, thereby controlling the microcontroller MCU to return to normal, without affecting the internal structure of the atomization device containing the microcontroller reset circuit 100, and it is convenient and fast.

[0038] In some embodiments, after the logic control unit 10 is powered on, if it receives a pulse signal sent by the monitoring pin WDI within a preset time and determines that the microcontroller MCU is in a normal state, the logic control unit 10 does not generate an initial reset signal.

[0039] Among them, the preset time can be, for example, 2S, 3S, 3.1S, 3.2S, 3.3S, 3.4S, 3.5S, 3.6S, 3.7S or 4S, and there is no limitation here.

[0040] That is to say, when the microcontroller MCU is normal, even if the USB interface of the logic control unit 10 is connected to the power supply 40 through a charging cable, the logic control unit 10 can continuously receive the pulse signal sent by the monitoring pin WDI of the microcontroller MCU, so as to determine that the microcontroller MCU is in a normal state and will not generate an initial reset signal, which will affect the normal operation of the microcontroller MCU and will not have an adverse impact on the overall atomization device system.

[0041] In some embodiments, the monitoring pin WDI of the microcontroller MCU can continuously send pulse signals to the logic control unit 10 at a preset speed and a preset time interval.

[0042] The preset speed can be, for example, 1 time / second, 2 times / second or other values, which are not limited here.

[0043] The preset time interval can be, for example, 1 second, 1.1 seconds, 1.2 seconds, 1.3 seconds, 1.4 seconds, 1.5 seconds, 1.6 seconds, 1.7 seconds, 1.8 seconds or 1.9 seconds, which are not limited here.

[0044] That is to say, the microcontroller MCU of the present application can continuously send pulse signals to the logic control unit 10 through the monitoring pin WDI at a preset speed and a preset time interval. If the microcontroller MCU suddenly stops sending pulse signals, the logic control unit 10 can react in time and control the microcontroller MCU to return to normal.

[0045] When the monitoring pin WDI stops sending pulse signals to the logic control unit 10 and the logic control unit 10 does not receive the pulse signal sent by the monitoring pin WDI within a preset time, it is determined that the microcontroller MCU is in an abnormal state, and an initial reset signal is output to the level conversion unit 20.

[0046] It can be understood that since the microcontroller MCU can continuously send pulse signals to the logic control unit 10 through the monitoring pin WDI at a preset speed and a preset time interval when it is in a normal operation state, the logic control unit 10 will also continuously receive the pulse signal. Therefore, when it does not receive the pulse signal, it can accurately determine that the microcontroller MCU is in an abnormal state at this time.

[0047] Please refer to again Figure 1, in some embodiments, the logic control unit 10 includes an operation monitor 14, a power-on controller 15, and a signal generator 16. The first end 141 of the operation monitor 14 is connected to the monitoring pin WDI, and the second end 142 of the operation monitor 14 is connected to the signal generator 16. The first end 151 of the power-on controller 15 is connected to the power supply 40. The second end 152 of the power-on controller 15 is connected between the operation monitor 14 and the signal generator 16. The power-on controller 15 is used to control the logic control unit 10 to be in the power-on state. The first end 161 of the signal generator 16 is connected to the power supply 40, the second end 162 of the signal generator 16 is connected to the level conversion unit 20, and the third end 333 of the signal generator 16 is grounded.

[0048] When the microcontroller MCU is abnormal, the operation monitor 14 issues a trigger reset signal to the signal generator 16. The signal generator 16 receives the trigger reset signal and issues an initial reset signal to the level conversion unit 20.

[0049] Specifically, the operation monitor 14 can be a hardware watchdog. The working principle of the hardware watchdog is to use a dedicated hardware circuit to implement the watchdog function, and the hardware circuit can be, for example, a reset chip.

[0050] The internal circuit of the hardware watchdog usually includes a timer and a reset signal output terminal. Under normal circumstances, the timer is cleared by the watchdog signal sent by the monitoring pin WDI of the microcontroller MCU. The watchdog signal is usually a periodic signal used to reset the timer.

[0051] That is to say, the pulse signal in this application is the watchdog signal. When the timer times out and does not receive the watchdog signal and never receives the watchdog signal, the reset signal output terminal can output a trigger reset signal to trigger the reset operation of the microcontroller MCU.

[0052] In detail, when the microcontroller MCU is working properly, after inserting a charging cable at the first end 151 of the power-on controller 15 of the logic control unit 10 and then connecting it to the power supply 40 through the charging cable, the logic control unit 10 is powered on. The WDI pin of the microcontroller MCU outputs a watchdog signal to clear the timer in the hardware watchdog inside the logic control unit 10 according to the watchdog signal. The timer of the logic control unit 10 never generates a trigger reset signal, which has no impact on the microcontroller MCU, and the atomization device works normally.

[0053] When the microcontroller MCU malfunctions, when a charging cable is inserted into the first terminal 151 of the power-on controller 15 of the logic control unit 10 and connected to the power supply 40, the logic control unit 10 is powered on. The WDI pin of the microcontroller MCU does not output a watchdog signal, and the timer in the hardware watchdog issues a trigger reset signal, that is, the logic control unit 10 generates a trigger reset signal. The trigger reset signal is sent to the level conversion unit 20 and the reset unit 30, which can reset the microcontroller MCU and enable the atomization device to resume normal operation.

[0054] In some embodiments, the reset unit 30 includes a reset power supply 31, a reset resistor 32, and a reset capacitor 33. The first terminal 321 of the reset resistor 32 is connected to the reset power supply 31, and the second terminal 322 of the reset resistor 32 is connected between the monitoring pin WDI and the level conversion unit 20. The first terminal 331 of the reset capacitor 33 is connected between the monitoring pin WDI and the level conversion unit 20, and the second terminal 332 of the reset capacitor 33 is grounded. The reset power supply 31 can be an external power supply represented by VCC in Figure 1 the present application.

[0055] It can be understood that since the first terminal 321 of the reset resistor 32 is connected to the reset power supply 31, the second terminal 322 of the reset resistor 32 is connected between the monitoring pin WDI and the level conversion unit 20, and the second terminal 332 of the reset capacitor 33 in the reset unit 30 is grounded. Therefore, when the microcontroller MCU is operating normally, when the reset unit 30 does not receive the recognizable reset signal sent by the level conversion unit 20, the microcontroller MCU can also be normally reset according to the reset unit 30, without affecting the normal reset of the microcontroller MCU.

[0056] The power supply 40 of the present application can be a USB interface power supply. That is to say, the logic control unit 10 of the present application can always be externally connected to the USB interface power supply through a charging cable, so that the logic control unit 10 is always in a powered-on state, facilitating timely handling of abnormal conditions of the microcontroller MCU at any time, thereby triggering a reset in a timely manner and enabling the microcontroller MCU to resume normal operation.

[0057] It can be understood that when it is necessary to monitor in real time whether the microcontroller MCU malfunctions, the logic control unit 10 can be always connected to the power supply 40 through a charging cable. In addition, the logic control unit 10 can also be not connected to the power supply 40, that is, the power supply 40 is disconnected from the logic control unit 10. When the reset unit 30 connected to the microcontroller MCU cannot reset the microcontroller MCU normally, then the logic control unit 10 is connected to the power supply 40 through a charging cable, so as to reset the microcontroller MCU and restore it to a normal working state.

[0058] Specifically, when the logic control unit 10 is not connected to the power supply 40, the reset unit 30 can enable the microcontroller MCU to be normally reset, and the logic control unit 10, the level conversion unit 20, and the reset unit 30 are in an inoperative state.

[0059] That is to say, in the microcontroller reset circuit 100 of the present application, the logic control unit 10 may not be connected to the power supply 40. At this time, the microcontroller MCU can be normally reset only through the reset unit 30, while the logic control unit 10, the level conversion unit 20, and the reset unit 30 are all in an inoperative state. That is, at this time, there is no need to monitor the operating state of the microcontroller MCU, which can save energy consumption.

[0060] If it is found that the reset unit 30 cannot enable the microcontroller MCU to be normally reset, it can be determined that the microcontroller MCU has an abnormal situation. At this time, a charging line can be inserted into the first end 151 of the power-on controller 15 of the logic control unit 10 and connected to the power supply 40 to generate a trigger reset signal, so as to enable the microcontroller MCU to resume normal reset.

[0061] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
