The terms used in the description of the utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the utility model. As used herein, the term "and/or" 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 electronic cigarettes, and in this case, the atomizing circuit can be a cigarette rod. The atomizer is detachably connected to the voltage output end of the atomization circuit. Among them, the atomizer is used to atomize the smoke liquid. The voltage output terminal of the atomization circuit refers to the interface used by the cigarette rod in the traditional electronic cigarette to connect to the atomizer, such as the 510 interface. Moreover, the voltage output end of the atomization circuit can also be detachably installed with an adapter to charge external devices. Specifically, the adapter can be a USB (Universal Serial Bus, universal serial bus) adapter, that is, to convert the voltage output terminal (for example, 510 interface) of the atomization circuit into a USB interface. Then, when the voltage output terminal of the atomization circuit is installed After installing the USB adapter, the atomization circuit can charge external devices through the USB interface.

In addition, please refer to FIG. 1 , the atomization circuit includes a battery assembly (not shown in the figure), a control circuit 100 and a current detection circuit 200 . The battery pack is electrically connected to the control circuit 100 and the current detection circuit 200 respectively. The control circuit 100 and the current detection circuit 200 are respectively used to electrically connect the load 300 of the atomization circuit through the voltage output terminal. The current detection circuit 200 is also electrically connected to the control circuit 100 .

In the embodiment of the utility model, the load 300 of the atomization circuit may be an atomizer or an external device, or the atomization circuit may be in an open state (that is, the voltage output terminal of the atomization circuit is not connected to any load). Wherein, the external device may be a mobile phone, a tablet computer, a wearable electronic device, and the like. When the load 300 of the atomization circuit is an atomizer, the atomization circuit can realize the smoking function. At this time, the working mode of the atomization circuit is the cigarette lighting mode; when the load 300 of the atomization circuit is an external device, the atomization circuit can When charging external devices, the working mode of the atomizing circuit is charging mode; when the atomizing circuit is in an open state, that is, when the atomizing circuit has no load installed, the working mode of the atomizing circuit is open mode.

The battery pack is used for power supply. Specifically, the battery pack may include a battery and a charging circuit. The current detection circuit 200 is used to detect the current value of the load 300 flowing into the atomization circuit, and feed back the current value to the control circuit 100 .

Moreover, as long as the control circuit 100 detects that the atomization circuit starts to work, it can start to execute the process of identifying the load 300 of the atomization circuit.

Specifically, the control circuit 100 can first output a detection voltage to the load 300 of the atomization circuit, and identify that the load 300 of the atomization circuit is an atomizer according to the current value flowing into the load 300 of the atomization circuit under the detection voltage, or External equipment, or the atomization circuit is in an open state, and then the atomization circuit is controlled to enter the corresponding working mode.

Since the load 300 of the atomization circuit is different, the current value flowing through the load 300 of the atomization circuit will be different after a certain detection voltage is applied (for example: when the detection voltage is 3V, if the load 300 of the atomization circuit is an atomization device, then there is current in the output circuit, that is, the current value flowing into the load 300 of the atomization circuit is greater than zero, and if the load 300 of the atomization circuit is an external device such as a mobile phone, a tablet computer or a wearable electronic device, the output circuit has no current. The current, that is, the current flowing into the load 300 of the atomization circuit is zero. In addition, if the atomization circuit is not connected to the load, the output circuit has no current, that is, the current is zero. Therefore, after the detection voltage is applied, the detection voltage of the atomization circuit The current value of the load 300 can identify that the load 300 of the atomization circuit is an atomizer, an external device or the atomization circuit is in an open circuit state. Further, the control circuit 100 can first output a small first detection voltage (such as 3V ), to identify whether the load 300 of the atomization circuit is an atomizer, if the current value flowing into the load 300 of the atomization circuit is greater than zero, then it is determined that the load 300 of the atomization circuit is an atomizer; if the load 300 flowing into the atomization circuit If the current of 300 is zero, it is determined that the load 300 of the atomization circuit is not an atomizer. After that, the control circuit 100 increases the output voltage to the second detection voltage (for example, increased to 5V) to identify whether the load 300 of the atomization circuit is If it is an external device or no load, if the current value flowing into the load 300 of the atomization circuit is greater than zero, it is determined that the load 300 of the atomization 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, it controls the atomization circuit to enter the charging mode. At this time, the control circuit 100 can convert the output voltage of the battery pack into 5V and input it to the external device through the adapter , so as to charge the external device. When the control circuit 100 recognizes that the load 300 of the atomization circuit is an atomizer, it controls the atomization circuit to enter the cigarette lighting mode. At this time, the control circuit 100 can convert the output voltage of the battery pack into a voltage suitable for the operation of the atomizer. (such as 3V voltage) and input to the atomizer, so that the smoke liquid is atomized through the atomizer. When the control circuit 100 recognizes that the atomization circuit is empty, it controls the atomization circuit to stop running, such as cutting off the power supply circuit of the battery pack. Optionally, the control circuit 100 can also control the atomization circuit to send out prompt information such as sound and light reminders or vibration reminders.

To sum up, the above-mentioned atomization circuit provided by the embodiment of the utility model can identify the load 300 of the atomization circuit through the current detection circuit 200 and the control circuit 100, so as to ensure that the atomization circuit does not matter whether it is a cigarette lighting function or a charging function.

At the same time, when the working mode of the atomization circuit does not match the load of the atomization circuit, the battery module still outputs voltage and may cause damage to the load, which prolongs the use time of the atomization circuit to a certain extent. .

In one embodiment, please refer 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 detection circuit 200 respectively. Specifically, the output terminal of the controller 110 is electrically connected to the input terminal of the output control unit 120, the first input terminal of the controller 110 is electrically connected to the output terminal of the current detection circuit 200, and the first input terminal of the controller 110 is used for The current value fed back by the current detection circuit 200 is received.

In addition, the output control unit 120 is not limited to having the above-mentioned functions, for example, it may also have functions such as filtering, over-current protection, over-voltage protection, and short-circuit protection, so as to improve the reliability of the atomization circuit.

The controller 110 is used to control the operation of the battery assembly, the load 300 of the atomization circuit and the output control unit 120 according to the current value of the load 300 of the atomization circuit. Specifically, the controller 110 can output the detection voltage to the load 300 of the atomization circuit through the output control unit 120, and identify the load 300 of the atomization circuit according to the current value of the load 300 of the atomization circuit under the detection voltage, so as to enter The working mode corresponding to the load 300 of the atomization circuit. Wherein, after the controller 110 outputs a corresponding control signal to make the control unit 120 output a detection voltage, the current detection circuit 200 detects the current value of the load 300 flowing into the atomization circuit, and feeds back to the controller 110 . The controller 110 can judge whether the load 300 of the atomization circuit is an atomizer or an external device or the atomization circuit is in an open circuit state according to the fed-back current value.

In one embodiment, please continue to refer to FIG. 2 , the atomization circuit further includes a voltage detection circuit 400 .

Specifically, the voltage detection circuit 400 is electrically connected to the second input terminal of the controller 110 in the control circuit 100 , and the second input terminal of the controller 110 is used to receive the voltage value detected by the voltage detection circuit 400 .

The voltage detection circuit 400 is used to detect the voltage value input to the load 300 of the atomization circuit, and feed back the voltage value to the control circuit 100 . The control circuit 100 is also used to adjust the voltage input to the load 300 of the atomization circuit according to the voltage value fed back by the voltage detection circuit 400, so as to ensure that the output voltage to the load 300 of the atomization 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 detection 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 cycle of the PWM signal, so that the output voltage input to the atomization circuit The voltage of the load 300 reaches the detection voltage.

In one embodiment, please continue to refer to FIG. 2 , the atomization circuit is provided with an interaction device 500 . The interaction device 500 is electrically connected with the control circuit 100 . Specifically, the interaction device 500 is electrically connected to the controller 110 .

Wherein, the interaction device 500 is used for receiving an operation signal for switching the working mode of the atomization circuit, and sending the operation signal to the control circuit 100 . Specifically, the interaction device 500 may include a button, a toggle switch or a touch screen, which is not limited in this embodiment. Therefore, the user can switch the working mode of the atomization circuit through buttons, toggle switches or touch screen. For example: taking buttons as an example, two different buttons (defined as the first button and the second button) can be set respectively, wherein the first button represents the charging mode, and the second button represents the cigarette lighting mode. When the user presses the first button, it is expected that the atomization circuit will switch to charging mode; when the user presses the second button, it is expected that the atomization circuit will switch to cigarette lighting mode; when neither the first button nor the second button is pressed, it is expected that the atomization circuit is open circuit. Moreover, the touch screen can also display the working mode of the atomization circuit in real time, so that the user can check it.

The control circuit 100 is also used for controlling the atomization circuit to switch to the 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.

Therefore, the atomization circuit provided by the embodiment of the utility model can switch the working mode automatically, and can also switch the working mode according to the user's choice.

It should be noted that the atomization circuit included in the above atomization device provided in this embodiment corresponds to the atomization circuit provided in the above embodiment, and will not be repeated here.

In another embodiment, a method for controlling an atomization circuit is provided, which can be executed by the control circuit 100 of the previous embodiment. Specifically, the atomization circuit control method can be executed by the controller 110 . Please refer to Figure 3, the atomization circuit control method includes the following contents.

Step S100. Output the detection voltage to the load 300 of the atomization circuit, obtain the current value passing through the load 300 of the atomization circuit under the detection voltage, and determine the corresponding working mode of the load 300 of the atomization circuit according to the current value.

Wherein, the working mode can be cigarette lighting mode, charging mode or open circuit mode. Since the load 300 of the atomization circuit is different, the current value flowing through the load 300 of the atomization circuit will be different after a certain detection voltage is applied (for example: when the detection voltage is 3V, if the load 300 of the atomization circuit is an atomization device, then there is current in the output circuit, that is, the current value flowing into the load 300 of the atomization circuit is greater than zero, and if the load 300 of the atomization circuit is an external device such as a mobile phone, a tablet computer or a wearable electronic device, the output circuit has no current. Current, that is, the current flowing into the load 300 of the atomization circuit is zero. In addition, if the atomization circuit is not connected to the load, the output circuit has no current), so after the detection voltage is applied, by detecting the load 300 of the atomization circuit The current value can identify that the load 300 of the atomization circuit is an atomizer, an external device or the atomization circuit is in an open state.

Step S200. Switch the atomization circuit to the working mode corresponding to the load 300 of the atomization circuit. The working modes include at least a cigarette lighting mode and a charging mode. .

When the control circuit 100 recognizes that the load 300 of the atomization circuit is an external device, it controls the atomization circuit to enter the charging mode. At this time, the control circuit 100 can convert the output voltage of the battery pack into 5V and output it, so as to supply power through the adapter. Charging external devices. When the control circuit 100 recognizes that the load 300 of the atomization circuit is an atomizer, it controls the atomization circuit to enter the cigarette lighting mode. At this time, the control circuit 100 can convert the output voltage of the battery pack into a voltage suitable for the operation of the atomizer. (such as 3V voltage) and output, so as to atomize the smoke liquid through the atomizer. When the control circuit 100 recognizes that the atomization circuit is empty, it controls the atomization circuit to stop running, such as cutting off the power supply circuit of the battery pack. Optionally, the control circuit 100 can also control the atomization circuit to send out prompt information such as sound and light reminders or vibration reminders.

In addition, the control circuit 100 can also use the current value fed back by the current detection circuit 200 to detect in real time whether an over-current phenomenon occurs, and if so, also cut off the charging circuit of the battery pack.

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

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

Wherein, when the load 300 of the atomization circuit is an atomizer, the atomization circuit can realize the smoking function, and the working mode of the atomization circuit at this time is the cigarette lighting mode. The first detection voltage is the voltage input to the atomizer when the atomization circuit can work normally in the cigarette lighting mode. Specifically, the first detection voltage may be between 2.5V and 3.5V, such as 3V. Therefore, the purpose of applying the first detection voltage is to detect whether the load 300 of the atomization circuit is an atomizer.

Since the working voltage of the atomizer is lower than the working voltage of the external device when charging, in other words, the output voltage of the atomizing circuit in the cigarette lighting mode is lower than the output voltage of the atomizing circuit in the charging mode, so the embodiment of the utility model first Whether the load 300 of the atomization circuit is an atomizer is detected through the first detection voltage, which can improve safety.

Step S120. Receive the first current value of the load 300 of the atomization circuit under the first detection voltage.

Step S130. If the first current value is within the first current range, it is determined that the load 300 of the atomization circuit is an atomizer.

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

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

Step S132. Determine that the load 300 of the atomization circuit is an atomizer.

Step S133. Adjust the output voltage to the load 300 of the atomization circuit until reaching the second detection voltage corresponding to the charging mode.

Wherein, the second detection voltage is the voltage input to the external device through the adapter when the atomization circuit can work normally in the charging mode. Specifically, this step may be: increasing the output voltage to the load 300 of the atomization circuit until reaching the second detection voltage corresponding to the charging mode. The second detection voltage can be between 4.5V and 5.5V, such as 5V. Therefore, the purpose of applying the second detection voltage is to detect whether the load 300 of the atomization circuit is an external device.

Step S134. Receive the second current value of the load 300 of the atomization circuit under the second detection voltage.

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

Step S135. If the second current value is within the second current range, it is determined that the load 300 of the atomization circuit is an external device.

Wherein, the second current range is the current range flowing into the external device when the atomization circuit operates normally in the charging mode. Since the second detection voltage corresponds to the charging mode, only when the load 300 of the atomization circuit is an external device, the atomization circuit can operate normally, and at this time the second current value is in the second current range; The load 300 is an atomizer or the atomization circuit is in an open state, and the atomization circuit cannot operate normally. At this time, 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 500mA and 1000mA. At this time, after the second detection voltage is applied, if it is determined that the second current value is between 500mA and 1000mA, it can be determined that the load 300 of the atomization circuit is a mobile phone.

Specifically, step S135 includes: judging whether the second current value is greater than the second threshold, if so, then judging that the load 300 of the atomizing circuit is an external device; otherwise, if the second current value is zero, judging that the atomizing circuit is in open state.

Wherein, the atomization circuit is in an open circuit state, in other words, the interface of the atomization circuit is not connected to any load. Therefore, the embodiment of the present utility model can respectively identify whether the load 300 of the atomization circuit is an atomizer, an external device or no load through the above implementation.

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

Wherein, the operation signal for switching the working mode may be a signal sent from the interaction device 500 to the control circuit 100 . Therefore, the atomization circuit control method provided by the embodiment of the utility model can not only switch the atomization circuit to the user's desired working mode according to the user's wishes, but also can identify the load 300 of the atomization circuit by itself, and switch to the atomization circuit. The working mode corresponding to the load 300.
