[0001] This application relates to the field of electronic cigarette technology, and in particular to a start-up control circuit, method, and electronic cigarette. Background Technology

[0002] Electronic cigarettes, also known as e-cigarettes, are electronic products used to replace traditional cigarettes. Electronic cigarettes mainly consist of a battery, microphone, e-liquid, atomizer coil, and controller. In electronic cigarettes, the atomizer typically uses a heating coil unit made of metal materials with different temperature properties to heat and atomize the e-liquid. The microphone senses changes in the inhaled airflow; when the airflow pressure reaches a certain threshold, it guides the heating of the e-liquid.

[0003] Currently, most disposable e-cigarettes use an integrated cotton core as the atomizer, storing e-liquid via pre-filling or post-filling. During storage and transportation, pre-filled or post-filled e-cigarettes may spontaneously activate due to vibrations and pressure, causing e-liquid leakage, which can burn the cotton core, producing a burnt taste and harming the user.

Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0061] Figure 1 This is one of the structural block diagrams of a startup control circuit according to an embodiment, referencing... Figure 1 As shown, the start-up control circuit of this embodiment includes: microphone circuit 100, switch module 200, output module 300 and control module 400.

[0062] The microphone circuit 100 generates a microphone signal based on the inhalation state of the electronic cigarette when it is in working condition; the switch module 200 outputs a power-on signal according to the power-on command; the output module 300 is connected to the load and supplies power to the load when a drive signal is received; the control module 400 is connected to the microphone circuit 100, the switch module 200, and the output module 300 respectively, and controls the microphone circuit 100 to be in working condition when the received power-on signal meets the first preset condition, and outputs a drive signal when the received microphone signal meets the second preset condition.

[0063] The power-on command can be a command generated after the soft switch or physical button of the electronic cigarette is touched. When the switch module 200 receives the command, it outputs a circuit power-on signal to the control module 400 to instruct the control module 400 to make a preliminary power-on judgment.

[0064] The control module 400 has a first terminal connected to the switch module 200 to power on the circuit when the circuit power-on signal output by the switch module 200 meets a first preset condition. The control module 400's second terminal is connected to the microphone circuit 100 to trigger the microphone circuit 100 to operate and generate a microphone signal based on the electronic cigarette's inhalation state when the circuit is powered on. When the microphone signal received by the control module 400 meets a second preset condition, it outputs a drive signal. Optionally, the microphone signal can be a signal with different level states. The first preset condition can be three low-level signals triggered by the electronic cigarette switch, and the second preset condition can be a low-level signal output after three consecutive inhalations of the electronic cigarette.

[0065] The first end of the output module 300 is connected to the third end of the control module 400, and the second end of the output module 300 is connected to the load, so that when the control module 400 outputs a drive signal, the connection between the power supply and the load is turned on, thereby controlling the output module 300 to supply power to the load.

[0066] Therefore, the start-up control circuit provided in this embodiment outputs a start-up signal from the switch module 200 according to the start-up command. When the start-up signal meets the first preset condition, the control module 400 controls the microphone circuit 100 to be in working state and generates a microphone signal according to the inhalation state of the electronic cigarette. When the microphone signal meets the second preset condition, the control module 400 controls the output module 300 to supply power to the load, thereby realizing the start-up control of the electronic cigarette and avoiding the burnt smell produced after the electronic cigarette is turned on, which may cause harm to the human body.

[0067] Figure 2 This is a second block diagram of the start-up control circuit according to one embodiment, referencing... Figure 2In this embodiment, the microphone circuit 100 includes a microphone activation unit 110 and a microphone 120. The microphone activation unit 110 is connected to the control module 400 and is used to output an activation control signal under the control of the control module 400. The microphone 120 is connected to both the microphone activation unit 110 and the control module 400 and is used to detect the inhalation state of the electronic cigarette when the activation control signal is received and to output a microphone signal to the control module 400.

[0068] The microphone activation unit 110 is used to output an activation control signal to the microphone 120 under the control of the control module 400, triggering the microphone 120 to detect the inhalation state of the electronic cigarette, and the microphone 120 feeds back the detected inhalation state to the control module 400.

[0069] In one embodiment, such as Figure 3 As shown, the microphone start unit 110 includes resistor R14, resistor R9 and capacitor C2.

[0070] The first terminal of resistor R14 is connected to the positive terminal of the battery cell, the second terminal of resistor R14 is connected to the first terminal of capacitor C2, the second terminal of capacitor C2 is grounded to the first terminal of resistor R9, the second terminal of resistor R9 is connected to the first terminal of microphone 120, and the second terminal of microphone 120 is connected to control module 400.

[0071] When the circuit is powered on, the microphone 120 receives the start control signal from the microphone start unit 110 to detect the electronic cigarette inhalation status and outputs a microphone signal to the control module 400 so that the control module 400 outputs a drive signal according to the received microphone signal.

[0072] Among them, the microphone 120 can be a three-line oil-proof and anti-backflow microphone.

[0073] In one embodiment, such as Figure 4 As shown, the switch module 200 includes a resistor R2, the first end of which is connected to the positive terminal of the battery cell, and the second end of which is connected to the control module 400.

[0074] In one embodiment, such as Figure 5 As shown, the output module 300 includes a battery unit 310 and a switch unit 320.

[0075] Battery unit 310; switch unit 320, for connection to load, for connecting the battery unit 310 to the load upon receiving a drive signal, so that the battery unit 310 supplies power to the load.

[0076] Alternatively, please continue to refer to Figure 5The switching unit 320 includes resistors R13 and R15 and a MOSFET Q1. The first terminal of the switching unit 320 is connected to the load, and the second terminal of the switching unit 320 is connected to the control module 400 so that when the third terminal of the switching unit 320 is connected to the battery cell, power is supplied to the load. Resistor R17 is used to increase the input impedance.

[0077] In one embodiment, such as Figure 6 As shown, the control module 400 includes a control unit 410 and a power supply unit 420. The control unit 410 is connected to the microphone circuit 100, the switch module 200, and the output module 300, and is used to output a drive signal when a power-on signal is received; the power supply unit 420 is connected to the control unit 410 and is used to supply power to the control unit 410.

[0078] When the power supply unit 420 is connected to the power supply, it continuously supplies power to the control unit 410 to ensure that the control unit 410 works normally. When the control unit 410 is in operation, it outputs a drive signal according to the received power-on signal.

[0079] The control unit 410 can be an MCU control chip, which has a software programming port for writing MCU programs through software programming.

[0080] The power supply unit 420 includes a power supply terminal and a filter circuit connected to each other. The filter circuit may include a resistor R20 and a capacitor C3 to filter the signal output from the power supply terminal before outputting it.

[0081] Optionally, the power supply unit 420 may also include a resistor R21, which is equivalent to a resistor fuse to prevent overcurrent input during circuit power supply and to protect the circuit.

[0082] In one embodiment, such as Figure 7 As shown, the start-up control circuit also includes a charging module 500.

[0083] The charging module 500 is connected to the control module 400 and the battery unit 310, and is used to charge the battery unit 310 according to the power supply signal from the external power source under the control of the control module 400.

[0084] The charging module 500 includes: an interface unit 510 for connecting to an external power source; a feedback unit 520 for outputting a connection feedback signal to the control module 400 when the interface unit 510 is connected to an external power source, so that the control module 400 outputs a charging enable signal; and a charging unit 530 for charging the battery unit 310 according to the power supply signal of the external power source under the control of the charging enable signal.

[0085] The charging interface of the interface unit 510 can be a TYPE-C USB connector; the feedback unit 520 can be a circuit composed of two sets of voltage-reducing resistors; and the charging component of the charging unit 530 can be a micro-source lithium battery charging chip.

[0086] In one embodiment, such as Figure 8 As shown, the start-up control circuit also includes a power detection module 600.

[0087] A power detection module 600 is connected to the battery unit 310 and outputs a charging feedback signal to the control module 400 when the power of the battery unit 310 is lower than a threshold. The control module 400 controls the charging module 500 to charge the battery unit 310 according to the charging feedback signal.

[0088] The threshold can be set according to actual needs. When the battery cell 310's power level is below the threshold, its power may be insufficient to supply power to other modules, thus requiring timely charging. By detecting the battery cell 310's power level through the power detection module 600, the control module 400 can promptly control the charging module 500 to charge the battery cell 310, ensuring normal power supply to other modules.

[0089] Optionally, the power detection module 600 can detect the power level of the battery unit 310 when the electronic cigarette is in standby mode, and promptly report the current power level information to the control module 400 when the power level is lower than the threshold. This allows the control module 400 to control the charging module 500 to charge the battery unit 310 while in standby mode, thereby avoiding charging during the user's smoking process and improving the safety, reliability, and user experience of the electronic cigarette.

[0090] In one embodiment, such as Figure 9 As shown, the start-up control circuit also includes a load detection module 700.

[0091] The load detection module 700 is used to connect to the load and detect the working status of the load. When the load is in an abnormal working state, it outputs an abnormal feedback signal to the control module 400. The control module 400 is used to control the output module 300 to stop supplying power to the load according to the abnormal feedback signal.

[0092] The abnormal feedback signal can be, for example, a low-level signal. Abnormal operating states can include, for example, a short circuit in the load, a timeout (e.g., a timeout during inhalation), or insufficient battery power preventing the load from functioning properly. When the load detection module 700 detects an abnormal operating state, it outputs a low-level signal to the control module 400. This allows the control module 400 to promptly control the output module 300 to stop supplying power to the load. This prevents abnormal temperature fluctuations in the electronic cigarette caused by continuous power supply during an abnormal operating state, thus improving the safety and reliability of the electronic cigarette.

[0093] Alternatively, please continue to refer to Figure 9 The load detection module 700 may include resistors R22, R23, R24, and R25 and MOSFET Q2. Resistors R22, R23 and MOSFET Q2 can form a constant current source circuit to detect whether the output module 300 is connected to a load, the resistance value of the load, and whether the load is short-circuited.

[0094] This application also provides an electronic cigarette, including: a load; and a start-up control circuit as described in the above embodiment. The electronic cigarette of this embodiment can be start-up controlled to prevent it from automatically starting during storage and transportation, thereby burning the wick and producing a burnt taste, which could harm the human body.

[0095] The load can be a heating wire, which is an important component of the atomizing core in an electronic cigarette, responsible for heating and atomizing the e-liquid. It will not be specifically described or limited here.

[0096] In one embodiment, such as Figure 10 As shown, the electronic cigarette also includes a display module 800.

[0097] The display module 800 is connected to the control module 400. The control module 400 controls the display module 800 to output a first display signal upon receiving a circuit power-on signal. The first display signal indicates at least one of the following states: power-on, power-off, standby, short circuit, and battery level. Optionally, the first display signal can be an audible / visual prompt signal. The display module 800 can output different audible / visual prompt signals for different states. For example, when indicating power-on, the display module 800 can output a visual prompt signal lasting one second; when indicating power-off, the display module 800 can output a visual prompt signal five times consecutively; when the microphone 120 is activated, the display module 800 can output a visual prompt signal lasting one second.

[0098] The display module 800 includes several light-emitting units 810 connected in parallel.

[0099] Figure 11 Here is a flowchart of a startup control method according to one embodiment, with reference to... Figure 11 The activation control method is applied to electronic cigarettes and includes steps 112 to 116.

[0100] Step 112: Receive the circuit power-on signal output by the switch module according to the power-on command.

[0101] Step 114: When the power-on signal meets the first preset condition, control the microphone circuit to be in working state, wherein the microphone circuit is used to generate a microphone signal according to the inhalation state of the electronic cigarette when in working state.

[0102] Step 116: When the microphone signal meets the second preset condition, output a drive signal to control the output module to supply power to the load.

[0103] Steps 112 to 116 can be executed by the control module in the above embodiments. For relevant features, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0104] The startup control method provided in this embodiment receives a circuit startup signal output by the switch module according to the startup command. When the startup signal meets the first preset condition, the microphone circuit is controlled to be in working state. When the microphone circuit is in working state, a microphone signal is generated according to the inhalation state of the electronic cigarette. When the microphone signal meets the second preset condition, a drive signal is output to control the output module to supply power to the load. This can realize the startup control of the electronic cigarette and avoid the burnt smell produced after the electronic cigarette is self-started from causing harm to the human body.

[0105] In one embodiment, the microphone circuit includes a microphone activation unit and a microphone; step 114 includes:

[0106] Upon receiving a start control signal, the microphone is activated and a microphone signal is generated based on the inhalation state of the electronic cigarette. If no signal is input, the circuit enters a sleep state.

[0107] In one embodiment, the output module includes a battery unit and a switching unit; step 116 includes: upon receiving a drive signal, controlling the switching unit to connect the battery unit to the load, so that the battery unit supplies power to the load.

[0108] In one embodiment, reference Figure 12 The start-up control method also includes steps 122-124.

[0109] Step 122: When the battery cell's charge level is below a threshold, control the charging module to charge the battery cell.

[0110] Step 124: Detect the operating status of the load. If the load is in an abnormal operating state, control the output to stop supplying power to the load.

[0111] Optionally, the load will be in an abnormal operating state when smoking exceeds the time limit, the load is short-circuited, or the battery cell is low on power.

[0112] Figure 13 Here is a flowchart of step 122 in one embodiment, see reference. Figure 13 Step 122 includes sub-steps 132 to 134.

[0113] Step 132: Detect the battery cell's charge level. When the battery cell's charge level is below a threshold, control the charging module to charge the battery cell.

[0114] Step 134: When the battery cell's charge reaches the threshold, the charging module is released from its charging task, and the circuit enters a smoking standby state.

[0115] In one embodiment, based on a combination of the above embodiments, the activation control method may include:

[0116] When the e-cigarette is in standby mode, if the switch module receives a power-on command, it outputs a power-on signal. At this time, the display module can be controlled to display a prompt indicating that the device has entered unlock and power-on mode. If the power-on signal satisfies three low-level states, the microphone circuit is controlled to operate, allowing the microphone circuit to detect whether the user is smoking. When the user smokes, a microphone signal is generated. If the microphone signal satisfies three low-level states, a drive signal is output to control the output module to supply power to the load, thus putting the e-cigarette into operation and controlling the display module to display a power-on status prompt. Otherwise, the e-cigarette is controlled to switch to sleep mode, and the display module is controlled to display a sleep mode prompt.

[0117] Specifically, when the e-cigarette is in standby or sleep mode, the battery level is detected. When the battery level is below a threshold, the charging module is controlled to charge the battery and the display module is controlled to output a charging status prompt. When the battery level is above the threshold or the e-cigarette switches to working mode, the charging module is controlled to stop charging the battery.

[0118] Specifically, when the electronic cigarette is in operation, the operating status of the load is detected. When the load is in an overdue operating state, the control output module stops supplying power to the load and the control display module outputs an overdue operating prompt.

[0119] Therefore, the start-up control method, through the above steps, can control the electronic cigarette to start up and standby, and control whether the electronic cigarette performs charging or smoking tasks in the standby state. When the electronic cigarette is in working state, it detects the working status of the load. When the load times out, it controls the output module to stop supplying power to the load and controls the display module to output a timeout prompt. At the same time, it can make users more intuitively understand the current status of the electronic cigarette, thereby improving the user experience.

[0120] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0121] The start control device is used to execute the start control method in the above embodiments. For relevant features, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0122] This application embodiment also provides a start-up control device for receiving a circuit power-on signal output by a switch module according to a power-on command; controlling the microphone circuit to be in working state when the power-on signal meets a first preset condition, wherein the microphone circuit is used to generate a microphone signal according to the inhalation state of the electronic cigarette when in working state; and outputting a drive signal to control the output module to supply power to the load when the microphone signal meets a second preset condition.

[0123] The start-up control device provided in this embodiment outputs a power-on signal to the circuit according to the power-on command through the switch module. When the power-on signal meets the first preset condition, the microphone circuit is controlled to be in working state. When the microphone circuit is in working state, a microphone signal is generated according to the inhalation state of the electronic cigarette.
