In order to facilitate the understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the understanding of the present disclosure will be more fully understood.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning meaning meaning The terminology used herein is for the purpose of describing the particular embodiments, The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

An embodiment provides an atomization circuit. Specifically, the atomizing circuit can be applied to the electronic cigarette, and the atomizing circuit can be a tobacco rod. The atomizer is detachably connected to the voltage output of the atomizing circuit. Among them, the atomizer is used to atomize the liquid smoke. The voltage output end of the atomization circuit refers to the interface of the tobacco rod in the conventional electronic cigarette for connecting the atomizer, for example, the 510 interface. Moreover, the voltage output end of the atomizing circuit can also detachably mount the adapter to charge the external device. Specifically, the adapter can be a USB (Universal Serial Bus) adapter, that is, the voltage output end of the atomization circuit (for example, the 510 interface) is converted into a USB interface, and then, when the voltage output terminal of the atomization circuit is installed, After the USB adapter, the atomizing circuit can charge the external device through the USB interface.

In addition, referring to FIG. 1, the atomizing circuit includes a battery assembly (not shown), a control circuit 100, and a current detecting circuit 200. The battery packs are electrically connected to the control circuit 100 and the current detecting circuit 200, respectively. The control circuit 100 and the current detecting circuit 200 are respectively configured to electrically connect the load 300 of the atomizing circuit through the voltage output terminal. The current detecting circuit 200 is also electrically connected to the control circuit 100. In an embodiment of the invention, the battery assembly can be used as part of an atomizing circuit or separately from the atomizing circuit, but the battery assembly is always used to power the atomizing circuit.

In the embodiment of the present invention, the load 300 of the atomization circuit may be an atomizer or an external device, or the atomization circuit may also be in an open state (ie, no voltage is connected to the voltage output end of the atomization circuit). Among them, the external device can be a mobile phone, a tablet computer, and a wearable electronic device. When the load 300 of the atomization circuit is an atomizer, the atomization circuit can realize the smoking function. At this time, the operation mode of the atomization circuit is the cigarette light mode; when the load 300 of the atomization circuit is an external device, the atomization circuit can Charging the external device, the working mode of the atomizing circuit is the charging mode; when the atomizing circuit is in an open state, that is, when the atomizing circuit is not loaded, the working mode of the atomizing circuit is an open mode, that is, an atomizing circuit The voltage output does not output a voltage.

The battery pack is used to supply power. Specifically, the battery assembly may include a battery and a charging circuit. The current detecting circuit 200 is for detecting a current value of the load 300 flowing into the atomizing circuit and feeding back the current value to the control circuit 100. The control circuit 100 is configured to control the atomizing circuit to operate in an operating mode corresponding to the load 300 of the atomizing circuit based on the current value. Further, the control circuit 100 can start the process of acquiring the current value of the load 300 flowing into the atomizing circuit as long as it detects that the atomizing circuit starts operating.

Specifically, the control circuit 100 may first output a detection voltage to the load 300 of the atomization circuit, and identify the load 300 of the atomization circuit as an atomizer according to the current value of the load 300 flowing into the atomization circuit under the detection voltage, or The external device, or the atomizing circuit is in an open state, thereby controlling the atomizing circuit to enter a corresponding working mode; or directly controlling the atomizing circuit to enter the working mode corresponding to the load 300 according to the current value. It can be understood that the detection voltage can also be input to the load 300 of the atomization circuit by other devices. For example, the control circuit 100 can control the battery component to input the detection voltage to the load 300 of the atomization circuit.

Since the load 300 of the atomization circuit is different, the current value of the load 300 flowing through the atomization circuit after applying a certain detection voltage will be different (for example, when the detection voltage is 3V, if the load 300 of the atomization circuit is atomized) The output circuit has a current, that is, the current value of the load 300 flowing into the atomizing circuit is greater than zero, and if the load 300 of the atomizing circuit is an external device such as a mobile phone, a tablet computer, or a wearable electronic device, the output circuit does not have The current, that is, the current flowing into the load 300 of the atomizing circuit is zero. In addition, if the atomizing circuit is not connected to the load, the output circuit also has no current, that is, the current is zero, so after the detection voltage is applied, the atomizing circuit is detected. The current value of the load 300 can identify that the load 300 of the atomizing circuit is an atomizer, an external device, or an atomizing circuit is in an open state. Further, the control circuit 100 can first output a smaller first detecting voltage (for example, 3V). In order to identify whether the load 300 of the atomizing circuit is an atomizer, if the current value of the load 300 flowing into the atomizing circuit is greater than zero, it is determined that the load 300 of the atomizing circuit is If the current flowing into the load 300 of the atomizing circuit is zero, it is determined that the load 300 of the atomizing circuit is not the atomizer. Thereafter, the control circuit 100 increases the output voltage to the second detecting voltage (for example, to 5V) To identify whether the load 300 of the atomizing circuit is an external device or no load, and if the current value of the load 300 flowing into the atomizing circuit is greater than zero, it is determined that the load 300 of the atomizing circuit is an external device; if there is no current, it is determined as No load.

When the control circuit 100 recognizes that the load 300 of the atomization circuit is an external device, then the atomization circuit is controlled to enter the charging mode, at which time the control circuit 100 can convert the output voltage of the battery component to 5V voltage and input to the external device through the adapter. To charge the external device. When the control circuit 100 recognizes that the load 300 of the atomization circuit is an atomizer, then the atomization circuit is controlled to enter a cigarette light mode, at which time the control circuit 100 can convert the output voltage of the battery assembly into a voltage suitable for the operation of the atomizer. (for example, 3V voltage) and input to the atomizer to atomize the smoke liquid through the atomizer. When the control circuit 100 recognizes that the atomizing circuit is unloaded, it controls the atomizing circuit to stop operating, for example, cutting off the power supply circuit of the battery pack. Optionally, the control circuit 100 can also control the atomizing circuit to emit prompt information such as an audible or visual reminder or a vibration reminder.

In summary, the atomization circuit provided by the embodiment of the present invention can identify the load 300 of the atomization circuit, thereby ensuring that the atomization circuit can operate normally regardless of whether the cigarette light function or the charging function is applied to the electronic cigarette. In the middle, the use value of the electronic cigarette can be improved. At the same time, in the case that the working mode of the atomizing circuit does not match the load connected to the atomizing circuit, the battery component still outputs a voltage and may cause damage to the load, and the use of the atomizing circuit is prolonged to some extent. time.

In one embodiment, referring to FIG. 2, the control circuit 100 includes a controller 110 and an output control unit 120. The controller 110 is electrically connected to the output control unit 120 and the current detecting circuit 200, respectively. Specifically, the output of the controller 110 is electrically connected to the input of the output control unit 120, the first input of the controller 110 is electrically connected to the output of the current detecting circuit 200, and the first input of the controller 110 is used. The current value fed back by the current detecting circuit 200 is received. The output control unit 120 is also used to electrically connect the load 300 of the atomizing circuit.

The output control unit 120 is configured to adjust the voltage output by the battery component under the control of the controller 110. For example, the output control unit 120 can be a voltage converter, and the controller 110 controls the output voltage of the output control unit 120 through a PWM (Pulse Width Modulation) signal, and then the controller 110 can change by adjusting the duty ratio of the PWM signal. The output voltage of the control unit 120 is output. In addition, the output control unit 120 is not limited to having the above functions, and may further include functions such as filtering, overcurrent protection, overvoltage protection, and short circuit protection to improve the reliability of the atomization circuit.

The controller 110 is configured to control the output control unit 120 to output a detection voltage to the load 300 of the atomization circuit, and control the load corresponding to the load 300 of the atomization circuit in the atomization circuit according to the current value of the load 300 of the atomization circuit under the detection voltage. Work in working mode. Wherein, after the controller 110 outputs a corresponding control signal such that the control control unit 120 outputs the detected voltage, the current detecting circuit 200 detects the current value of the load 300 flowing into the atomizing circuit and feeds back to the controller 110. The controller 110 can determine whether the load 300 of the atomization circuit is an atomizer or an external device or the atomization circuit is in an open state according to the feedback current value. Optionally, the controller 110 directly determines the operating mode corresponding to the load 300 of the atomizing circuit according to the feedback current value.

In one of the embodiments, please continue to refer to FIG. 2, and the voltage detecting circuit 400 is further included in the atomizing circuit. The voltage detecting circuit 400 is for electrically connecting the load 300 of the atomizing circuit, and the voltage detecting circuit 400 is also electrically connected to the control circuit 100. Specifically, the voltage detection circuit 400 is electrically coupled to the second input of the controller 110 within the control circuit 100, and the second input of the controller 110 is configured to receive the voltage value detected by the voltage detection circuit 400.

The voltage detecting circuit 400 is for detecting a voltage value of the load 300 input to the atomizing circuit and feeding back the voltage value to the control circuit 100. The control circuit 100 is further configured to adjust the voltage of the load 300 input to the atomization circuit according to the voltage value fed back by the voltage detecting circuit 400 to ensure that the voltage output to the load 300 of the atomizing circuit is the above-mentioned detection voltage, thereby improving detection. The accuracy. For example, if the controller 110 finds that the voltage value fed back by the voltage detecting circuit 400 is lower than the detection voltage, the controller 110 increases the output voltage of the output control unit 120 by increasing the duty ratio of the PWM signal, thereby inputting to the atomizing circuit. The voltage of the load 300 reaches the detection voltage.

In one of the embodiments, with continued reference to FIG. 2, the atomizing circuit is provided with an interaction device 500. The interaction device 500 is electrically coupled to the control circuit 100. Specifically, the interaction device 500 is electrically connected to the controller 110.

The interaction device 500 is configured to receive an operation signal for switching an operation mode of the atomization circuit. Specifically, the interaction device 500 may include at least one of a button, a toggle switch, or a touch screen, which is not limited in this embodiment. Therefore, the user can switch the operation mode of the atomizing circuit by means of a button, a toggle switch or a touch screen. For example, taking a button as an example, two different buttons (defined as a first button and a second button) can be separately set, wherein the first button represents a charging mode, and the second button represents a cigarette mode, when the user presses the first button When the button is pressed, the atomization circuit is expected to switch to the charging mode. When the user presses the second button, the atomization circuit is expected to switch to the cigarette light mode. When the first button and the second button are not pressed, the atomization circuit is expected. In an open state. Moreover, the touch screen can also display the working mode of the atomizing circuit in real time for the user to view.

The control circuit 100 is further configured to control the atomization circuit to switch to an operation mode corresponding to the operation signal according to the operation signal received by the interaction device 500 for switching the operation mode of the atomization circuit. The operation signal for switching the working mode is, for example, a pressing operation signal of the user to the button; an operation signal of the user dialing the toggle switch; or an operation signal for the user to click or slide the touch screen.

Therefore, the atomization circuit provided by the embodiment of the present invention can automatically switch between the working mode and the working mode according to the user's selection. For example, as long as the control circuit 100 detects that the atomization circuit starts to work, it begins to recognize the load loaded at the voltage output end of the atomization circuit, and controls the atomization circuit to enter the corresponding working mode according to the recognized result; during the operation, If the control circuit 100 receives an operation signal from the interaction device 500 for switching the operation mode of the atomization circuit, the control circuit 100 controls the atomization circuit to switch to an operation mode corresponding to the operation signal.

It can be understood that, in other embodiments, there are other ways of switching the operation mode of the atomization circuit. For example, the atomization circuit may further include a wireless module to wirelessly receive the operation mode of the switching atomization circuit sent by the user through the smart device. The signal is sent to the control circuit 100.

The control circuit and the current detecting circuit are respectively configured to electrically connect the load of the atomizing circuit through the voltage output end, and the load of the atomizing circuit is the external device or the atomizer. The current detecting circuit is also electrically connected to the control circuit. In an embodiment of the invention, the battery assembly can be used as part of an atomizing circuit or separately from the atomizing circuit, but the battery assembly is always used to power the atomizing circuit.

The battery assembly is used for power supply. The current detecting circuit is configured to detect a current value of a load flowing into the atomizing circuit and feed back the current value to the control circuit. The control circuit is configured to control the atomization circuit to operate in an operation mode corresponding to a load of the atomization circuit according to the current value.

It should be noted that the atomization circuit in the atomization device provided by the embodiment of the present invention is the same as the atomization circuit provided in the above embodiments, and details are not described herein again.

In another embodiment, an atomization circuit control method is provided that can be performed by the control circuit 100 of the previous embodiment. Specifically, the atomization circuit control method can be performed by the controller 110. Referring to FIG. 3, the atomization circuit control method includes the following.

Step S100. Output a detection voltage to the load 300 of the atomization circuit, and acquire a current value of the load 300 passing through the atomization circuit at the detection voltage. Wherein, the atomization circuit is provided with a voltage output end, and the voltage output end can be connected to the atomizer for atomization or detachably mounting the adapter to charge the external device.

The working mode corresponding to the load is an operating mode corresponding to the load type, such as an operating mode corresponding to the atomizer, a working mode corresponding to the mobile phone, and the like. The working mode can be a cigarette light mode, a charging mode or an open circuit mode. Since the load 300 of the atomization circuit is different, the current value of the load 300 flowing through the atomization circuit after applying a certain detection voltage will be different (for example, when the detection voltage is 3V, if the load 300 of the atomization circuit is atomized) The output circuit has a current, that is, the current value of the load 300 flowing into the atomizing circuit is greater than zero, and if the load 300 of the atomizing circuit is an external device such as a mobile phone, a tablet computer, or a wearable electronic device, the output circuit does not have The current, that is, the current flowing into the load 300 of the atomizing circuit is zero. Further, if the atomizing circuit is not connected to the load, the output circuit also has no current), and therefore, after the detection voltage is applied, the load 300 of the atomizing circuit is detected. The current value identifies that the load 300 of the atomizing circuit is an atomizer, an external device, or an atomizing circuit that is in an open state.

Step S200. According to the current value, the atomizing circuit is controlled to operate in an operation mode corresponding to the load 300 of the atomizing circuit. The working mode includes at least a cigarette light mode and a charging mode.

When the control circuit 100 recognizes that the load 300 of the atomizing circuit is an external device, then the atomizing circuit is controlled to enter a charging mode, at which time the control circuit 100 can convert the output voltage of the battery component to a voltage of 5 V and output it, thereby being supplied through the adapter. External device charging. When the control circuit 100 recognizes that the load 300 of the atomization circuit is an atomizer, then the atomization circuit is controlled to enter a cigarette light mode, at which time the control circuit 100 can convert the output voltage of the battery assembly into a voltage suitable for the operation of the atomizer. (for example, 3V voltage) and output, so that the smoke liquid is atomized by the atomizer. When the control circuit 100 recognizes that the atomizing circuit is unloaded, it controls the atomizing circuit to stop operating, for example, cutting off the power supply circuit of the battery pack. Optionally, the control circuit 100 can also control the atomizing circuit to emit prompt information such as an audible or visual reminder or a vibration reminder. In the embodiment of the present invention, the atomization circuit first determines the type of the load 300 of the atomization circuit according to the current value, and then determines the operation mode corresponding to the load 300 of the atomization circuit according to the type of the load 300 of the atomization circuit. Optionally, the atomizing circuit can also directly determine the working mode corresponding to the load 300 of the atomizing circuit according to the current value.

Further, after the control circuit 100 controls the atomization circuit to enter the charging mode, during the charging process, the control circuit 100 can also monitor in real time whether the output voltage of the battery component is lower than a threshold that can be normally charged, and if so, cut off the charging of the battery component. Circuit. In addition, the control circuit 100 can detect whether an overcurrent phenomenon has occurred in real time by the current value fed back by the current detecting circuit 200, and if so, the charging circuit of the battery pack is also cut off.

In one embodiment, step S100 includes the following content, please refer to FIG. 4.

Step S110. Input a first detection voltage corresponding to the cigarette light mode to the load 300 of the atomization circuit.

Wherein, when the load 300 of the atomizing circuit is an atomizer, the atomizing circuit can realize the smoking function, and the working mode of the atomizing circuit is the cigarette light mode. The first detection voltage is a voltage input to the atomizer when the atomization circuit is able to operate normally in the cigarette light mode. Specifically, the first detection voltage may be between 2.5V and 3.5V, for example, 3V. Therefore, the first detection voltage is applied in order to detect whether the load 300 of the atomization circuit is an atomizer.

Since the operating voltage of the atomizer is lower than the operating voltage when the external device is charging, in other words, the output voltage of the atomizing circuit in the cigarette light mode is smaller than the output voltage of the atomizing circuit in the charging mode, the embodiment of the present invention first passes The first detection voltage detects whether the load 300 of the atomizing circuit is an atomizer, which can improve safety.

Step S120. Receive a first current value of the load 300 of the atomizing circuit at the first detection voltage.

When the first detection voltage is output, the current detecting circuit 200 can detect the first current value of the load 300 flowing into the atomizing circuit and transmit the first current value to the control circuit 100.

In one embodiment, step S200 includes the following content, please refer to FIG. 5.

Step S201. Determine whether the first current value is in the first current range. If yes, execute step S202; otherwise, execute step S130.

In the embodiment of the present invention, the first detection voltage is applied, in order to detect whether the load 300 of the atomization circuit is an atomizer, and if not, continue to apply other voltages to detect whether the load 300 of the atomization circuit is an external device or The atomizing circuit is in an open state.

Step S202 determines that the load 300 of the atomizing circuit is an atomizer, and the control atomizing circuit operates in an operating mode when the load 300 of the atomizing circuit is an atomizer.

Wherein, the first current range is a current range flowing through the atomizer when the atomizing circuit is in normal operation in the cigarette light mode. Since the first detection voltage corresponds to the cigarette light mode, the atomization circuit can operate normally only when the load 300 of the atomization circuit is the atomizer, and the first current value is in the first current range; The load 300 of the circuit is in an open state of the external device or the atomizing circuit, and the atomizing circuit cannot operate normally, and the first current value is outside the first current range.

Specifically, the first current range may be greater than zero. In other words, after the first detection voltage is applied, if it is determined that the first current value is greater than zero, it represents that there is current in the output circuit, and then it can be determined that the load 300 of the atomization circuit is an atomizer; if it is determined that the first current value is zero , there is no current in the output loop. At this time, it can be determined that the load 300 of the atomizing circuit is an external device or no load.

When the first current value is not in the first current range, step 100 further includes step 130, and step 130 is performed.

Step S130. Adjust the voltage output to the load 300 of the atomizing circuit until reaching the second detection voltage corresponding to the charging mode.

The second detection voltage is a voltage input to the external device through the adapter when the atomization circuit can work normally in the charging mode. Specifically, the step may be: increasing the voltage output to the load 300 of the atomizing circuit until reaching the second detection voltage corresponding to the charging mode. The second detection voltage can be between 4.5V and 5.5V, for example 5V. Therefore, the second detection voltage is applied in order to detect whether the load 300 of the atomization circuit is an external device.

Step S140 receives a second current value of the load 300 of the atomizing circuit at the second detection voltage.

After outputting the second detection voltage, the current detecting circuit 200 can detect the second current value flowing into the load 300 of the atomizing circuit and transmit the second current value to the control circuit 100.

After step S140, step S200 further includes step S203 and step S204.

Step S203. If the second current value is in the second current range, it is determined that the load 300 of the atomization circuit is an external device, and the control atomization circuit operates in an operation mode when the load 300 of the atomization circuit is an external device.

The second current range is a current range flowing into the external device when the atomizing circuit is in normal operation in the charging mode. Since the second detection voltage corresponds to the charging mode, the atomizing circuit can operate normally only when the load 300 of the atomizing circuit is an external device, and the second current value is in the second current range; and if the atomizing circuit is When the load 300 is an atomizer or the atomization circuit is in an open state, the atomization circuit cannot operate normally, and the second current value is outside the second current range.

Specifically, if the external device connected to the adapter is a mobile phone, the second current range may be a current range between 500 mA and 1000 mA. At this time, after the second detection voltage is applied, if it is determined that the second current value is between 500 mA and 1000 mA, it can be determined that the load 300 of the atomization circuit is a mobile phone.

Specifically, step S204 includes determining that the atomizing circuit is in an open state if the second current value is zero.

Wherein, the atomization circuit is in an open state, in other words, the interface of the atomization circuit is not connected to any load. Therefore, the embodiment of the present invention can separately identify whether the load 300 of the atomization circuit is an atomizer, an external device, or an empty load by the above implementation manner.

In one embodiment, before the step S100, the atomization circuit control method further includes: determining whether an operation signal for switching the operation mode is received, and if so, switching the atomization circuit to the operation according to the operation signal The working mode corresponding to the signal; otherwise, step S100 is performed.

The operation signal for switching the operation mode may be a signal transmitted by the interaction device 500 to the control circuit 100. Therefore, the atomization circuit control method provided by the embodiment of the present invention can switch the atomization circuit to the user's desired working mode according to the user's wishes, and can also identify the load 300 of the atomization circuit and switch to the atomization circuit. The working mode corresponding to the load 300.

In addition, in the embodiment of the present invention, the atomizing circuit first determines the type of the load 300 of the atomizing circuit according to the current value, and then determines the working mode corresponding to the load 300 of the atomizing circuit according to the type of the load 300 of the atomizing circuit. For example, the load 300 is obtained as an atomizer according to the first current value in the first current range, and the operation mode is determined to be the cigarette mode according to the load 300.

Optionally, the atomizing circuit can also directly determine the working mode corresponding to the load 300 of the atomizing circuit according to the current value. The corresponding relationship between the current value and the working mode may be pre-stored in the atomizing circuit, for example, the first current range, the second current range, and the current value are zero corresponding to the cigarette light mode, the charging mode, and the open circuit, respectively. When the first detection voltage is output to the load 300, if the first current value is in the first current range, the operation mode of the atomization circuit is directly switched to the cigarette light mode. If not in the first current range, outputting a second detection voltage to the load 300; if the second current value is in the second current range, directly switching the operation mode of the atomization circuit to the charging mode; if the second current value is zero , is the open circuit mode.
