Description

Technical Field

[0001] This application relates to the field of heating control technology, and in particular to an electronic atomizing device. Background Technology

[0002] With the development of science and technology and the increase in user demand, the functions of heat-generating devices are becoming increasingly diverse. For example, heat-generating devices not only include a heating element for heating, but also other communication devices for signal transmission with connected components, enabling more functions.

[0003] In traditional heat-generating devices, the heating element and the communication device are connected in parallel. This connection method simplifies the structural design and allows for communication without distinguishing between the correct and reverse orientation of the heat-generating device.

[0004] However, in practical applications, because the heating element and the communicating device are connected in parallel, current also flows through the heating wire while the communicating device is sending or receiving signals, causing the heating element to heat up and the temperature to rise. However, this type of heating is not what users need and may even pose certain safety hazards, resulting in low reliability of traditional heating devices. Utility Model Content

[0013] In one embodiment, the heating control circuit includes a controller, a first push-pull circuit, and a second push-pull circuit. The control terminals of the first push-pull circuit and the second push-pull circuit are both connected to the controller. The output terminal of the first push-pull circuit serves as the first terminal of the heating control circuit, and the output terminal of the second push-pull circuit serves as the second terminal of the heating control circuit.

[0014] In one embodiment, the heating control circuit further includes a demodulation circuit, and the controller is connected to the output of the first push-pull circuit through the demodulation circuit.

[0015] In one embodiment, the first push-pull circuit includes a first switch and a second switch with opposite polarities, and the second push-pull circuit includes a third switch and a fourth switch with opposite polarities.

[0016] The control terminals of the first and second switches are both connected to the controller. The first terminal of the first switch is used to connect to the power supply. The second terminal of the first switch is connected to the second terminal of the second switch and serves as the output terminal of the first push-pull circuit. The first terminal of the second switch is grounded.

[0017] The control terminals of the third and fourth switches are both connected to the controller. The first terminal of the third switch is used to connect to the power supply. The second terminal of the third switch is connected to the second terminal of the fourth switch and serves as the output terminal of the second push-pull circuit. The first terminal of the third switch is grounded.

[0018] In one embodiment, the heating control circuit further includes a first control switch and a second control switch. The control terminals of the first control switch and the second control switch are both connected to the controller. The first terminal of the first control switch is connected to the output terminal of the first push-pull circuit. The second terminal of the first control switch is connected to the second terminal of the second control switch and is connected to the end of the demodulation circuit away from the controller.

When heating is required, the heating control switch can be turned on to power on the heating element and generate heat to meet the heating demand. This electronic atomizing device can control the heating element to remain off while communicating, resulting in high reliability. Attached Figure Description

[0033] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0036] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0037] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0038] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0039] The electronic atomizing device provided in this application includes various devices that can be used to generate aerosols through atomization, and the specific type is not limited. In one embodiment, an electronic atomizing device is provided, which includes an atomizing device body and an atomizer. The atomizing device body and the atomizer are detachably connected. The atomizing device body is provided with a heating control circuit, and the atomizer is provided with a heating circuit.

[0040] The atomizing device body and the atomizer are detachably connected. When needed, the atomizer can be connected to the atomizing device body, allowing the heating circuit inside the atomizer to connect with the heating control circuit inside the atomizing device body. When the atomizer needs to be replaced or is no longer needed, it can be removed from the atomizing device body for convenient use. For example, the atomizing device body can be detachably connected to the atomizer via a pin.

[0041] Furthermore, when the atomizer is connected in the correct orientation to the atomizing device body, the heating circuit inside the atomizer is connected in the correct orientation to the heating control circuit inside the atomizing device body. When the atomizer is connected in the reverse orientation to the atomizing device body, the heating circuit inside the atomizer is connected in the reverse orientation to the heating control circuit inside the atomizing device body. It can be understood that correct and reverse orientation are two connection methods with opposite directions. For example, if the first end of the heating circuit is connected to the first end of the heating control circuit and the second end of the heating circuit is connected to the second end of the heating control circuit (correct orientation), then the first end of the heating circuit is connected to the second end of the heating control circuit and the second end of the heating circuit is connected to the first end of the heating control circuit (reverse orientation).

[0042] The electronic atomizing device also includes an atomizing medium. When the heating element in the heating circuit is working, its temperature rises, which can heat the atomizing medium, causing it to atomize and produce an aerosol for the user.

[0043] For example, such as Figure 1 and Figure 2As shown, the heating circuit 100 includes a communication device 102, a heating control switch Q5, and a heating element 104. The first terminal of the heating control switch Q5 is connected to the first terminal of the heating element 104, the control terminal of the heating control switch Q5 is connected to the second terminal of the heating element 104 and the second terminal of the communication device 102, and the second terminal of the heating control switch Q5 is connected to the first terminal of the communication device 102. Figure 1 As shown, when the heating circuit 100 and the heating control circuit 200 are directly connected, the first end of the communication device 102 is connected to the first end of the heating control circuit 200, and the second end of the communication device 102 is connected to the second end of the heating control circuit 200. Figure 2 As shown, when the heating circuit 100 and the heating control circuit 200 are reversed, the first end of the communication device 102 is connected to the second end of the heating control circuit 200, and the second end of the communication device 102 is connected to the first end of the heating control circuit 200.

[0044] The communication device 102 is used for signal transmission with the heating control circuit 200. The heating element 104 is used to generate heat when the heating control switch Q5 is turned on, and also to stop generating heat when the heating control switch Q5 is turned off.

[0045] The communication device 102 includes a device with communication functionality, namely a chip capable of signal transmission, which can both receive and output signals. Both the first and second ends of the communication device 102 are used to connect to the heating control circuit 200 for signal transmission. For example, when a loop is formed between the communication device 102 and the heating control circuit 200, the communication device 102 can output signals to the heating control circuit 200 and also receive signals from the heating control circuit 200.

[0046] For example, the communication device 102 stores the default operating parameters of the heating circuit 100. The communication device 102 can output the default operating parameters to the heating control circuit 200, so that the heating control circuit 200 controls the operating state of the heating circuit 100 according to the default operating parameters, and the heating circuit 100 operates according to the default operating parameters. The type of communication device 102 is not unique. For example, the communication device 102 is a communication chip, and a communication chip can integrate various devices to achieve richer functions.

[0047] The heating element 104 is disposed in the circuit. Upon energization, the heating element 104 operates and generates heat, causing its temperature to rise. The heating element 104 is used to heat the atomizing medium, causing it to atomize and generate an aerosol. The heating element 104 ceases operation and heating or stops generating heat after power is de-energized. The structure of the heating element 104 is not unique. For example, the heating element 104 can be a heating wire. When energized, the heating wire, due to its internal resistance, can convert electrical energy into heat energy, thus generating heat. Optionally, the heating wire can be a coil, which can be connected in the circuit and generates heat upon energization. The heating power of the coil can also be adjusted by adjusting the number of turns, etc., providing flexibility in its use.

[0048] The first terminal of the heating control switch Q5 is connected to the first terminal of the heating element 104. The control terminal of the heating control switch Q5 is connected to the second terminal of the heating element 104 and the second terminal of the communication device 102, and is also connected to the heating control circuit 200. The second terminal of the heating control switch Q5 is connected to the first terminal of the communication device 102, and is also connected to the heating control circuit 200. The heating control switch Q5 is in a conducting or turning-off state based on the voltage applied to its control terminal. Furthermore, the heating control switch Q5 is in a conducting or turning-off state based on the voltage difference between the voltage applied to its control terminal and the voltage applied to its first terminal. That is, the heating control switch Q5 is in a conducting or turning-off state based on the voltage difference across the heating element 104.

[0049] When the heating control switch Q5 is turned on, the first end of the heating element 104 can be connected to the heating control circuit 200 through the turned-on heating control switch Q5, and the second end of the heating element 104 is also connected to the heating control circuit 200. In this case, the heating element 104 can receive electrical energy from the heating control circuit 200, and the heating element 104 generates heat. Furthermore, in this case, the first and second ends of the communication device 102 are also connected to the heating control circuit 200, enabling signal transmission with the heating control circuit 200.

[0050] When the heating control switch Q5 is turned off, the first end of the heating element 104 cannot be connected to the heating control circuit 200, and the heating element 104 does not heat up. In this case, the first and second ends of the communication device 102 are connected to the heating control circuit 200, enabling signal transmission with the heating control circuit 200.

[0051] In this embodiment, the heating circuit 100 includes a communication device 102, a heating control switch Q5, and a heating element 104. The first end of the heating control switch Q5 is connected to the first end of the heating element 104. The control end of the heating control switch Q5 is connected to the second end of the heating element 104 and the second end of the communication device 102. The second end of the heating control switch Q5 is connected to the first end of the communication device 102. Both the first and second ends of the communication device 102 are used to connect to the heating control circuit 200. The communication device 102 is used for signal transmission with the heating control circuit 200. The heating element 104 is used to generate heat when the heating control switch Q5 is turned on, and to stop generating heat when the heating control switch Q5 is turned off. Therefore, when signal transmission is required, the heating element 104 can be turned off by controlling the heating control switch Q5 to stop working and generating heat, at which point only the communication device 102 transmits the signal. When heating is required, the heating element 104 can be turned on by controlling the heating control switch Q5 to generate heat and meet the heating requirements. The heating circuit 100 can control the heating element 104 to not heat up while communicating, and has high reliability.

[0052] For example, in one embodiment, the communication device 102 is an anti-counterfeiting chip. The anti-counterfeiting chip can send encrypted information to the heating control circuit 200. The encrypted information may include information identifying the heating circuit 100. After processing the received encrypted information, the heating control circuit 200 can identify whether the currently connected heating circuit 100 meets preset conditions, such as whether it is a heating circuit 100 with a binding relationship. Therefore, based on the identification result, the connection state between the heating control circuit 200 and the heating circuit 100 can be controlled to control whether the heating control circuit 200 interacts with or does not interact with the heating circuit 100. For example, when the heating control circuit 200 identifies the currently connected heating circuit 100 as meeting preset conditions based on the received encrypted information, it indicates that the current heating circuit 100 is an authorized circuit with a binding relationship. Then, the heating control circuit 200 connects to the heating circuit 100 and controls the heating circuit 100 to operate according to preset requirements. It is understood that in other embodiments, the anti-counterfeiting chip can also interact with the heating control circuit 200 using other types of signals.

[0053] In this embodiment, the communication device 102 is an anti-counterfeiting chip. The anti-counterfeiting chip can transmit encrypted information, which helps to improve the security performance of the heating circuit 100.

[0054] The type of heating control switch Q5 is not unique. For example, in one embodiment, the heating control switch Q5 is an NMOS transistor. The gate of the NMOS transistor serves as the control terminal of the heating control switch Q5, connected to the second terminal of the heating element 104 and the second terminal of the communication device 102, and also connected to the heating control circuit 200. The source of the NMOS transistor serves as the first terminal of the heating control switch Q5, connected to the first terminal of the heating element 104. The drain of the NMOS transistor serves as the second terminal of the heating control switch Q5, connected to the first terminal of the communication device 102, and also connected to the heating control circuit 200.

[0055] The NMOS transistor is turned on when its gate voltage is higher than its source voltage, and turned off when its gate voltage is lower than its source voltage. Therefore, the on-state of the NMOS transistor can be controlled by adjusting its gate and source voltages. It is understood that in other embodiments, the type of the heating control switch Q5 can also be other, as long as those skilled in the art deem it feasible.

[0056] In this embodiment, the heating control switch Q5 is an NMOS transistor. The heating state of the heating element 104 is controlled by the on or off state of the NMOS transistor. The NMOS transistor has low on-resistance and strong transient response capability, which is beneficial to improving the working performance of the heating circuit 100.

[0057] In addition, the heating control circuit 200 is connected to the heating circuit 100. For example, the heating control circuit 200 may be connected to the first and second terminals of the communication device 102 in the heating circuit 100.

[0058] Among them, such as Figure 3 As shown, the heating control circuit 200 includes a controller 202, a first push-pull circuit 204, and a second push-pull circuit 206. The control terminals of both the first push-pull circuit 204 and the second push-pull circuit 206 are connected to the controller 202. The output terminal of the first push-pull circuit 204 serves as the first terminal of the heating control circuit 200. When the heating circuit 100 and the heating control circuit 200 are connected in the correct orientation, it is connected to the first terminal of the communication device 102. When the heating circuit 100 and the heating control circuit 200 are connected in reverse orientation, it is connected to the second terminal of the communication device 102. The output terminal of the second push-pull circuit 206 serves as the second terminal of the heating control circuit 200. When the heating circuit 100 and the heating control circuit 200 are connected in the correct orientation, it is connected to the second terminal of the communication device 102. When the heating circuit 100 and the heating control circuit 200 are connected in reverse orientation, it is connected to the first terminal of the communication device 102. Figure 3 Only the case where the heating circuit 100 and the heating control circuit 200 are connected in the correct orientation is shown.

[0059] The controller 202 is connected to the control terminals of the first push-pull circuit 204 and the second push-pull circuit 206, and is used to control the operating states of the first push-pull circuit 204 and the second push-pull circuit 206 by sending signals to them. Furthermore, the controller 202 can be connected to the control terminals of the first push-pull circuit 204 and the second push-pull circuit 206 through different ports, so that the signals sent to the control terminals of the first push-pull circuit 204 and the second push-pull circuit 206 are independent of each other, ensuring that the operating states of the first push-pull circuit 204 and the second push-pull circuit 206 do not affect each other, allowing for more possible combinations.

[0060] The output terminals of the first push-pull circuit 204 and the second push-pull circuit 206 are respectively used to connect to the two ends of the communication device 102. Because the first push-pull circuit 204 and the second push-pull circuit 206 operate in different states, the voltage output from the first push-pull circuit 204 to the first or second end of the communication device 102 is different, and the voltage output from the second push-pull circuit 206 to the second or first end of the communication device 102 is different. Therefore, the control terminal of the heating control switch Q5 in the heating circuit 100, the second end of the heating element 104, and the third end of the heating control switch Q5 can have different voltage states, so that the heating switch is in a conducting or turning-off state, thereby controlling whether the heating element 104 heats up.

[0061] In this embodiment, the heating control circuit 200 includes a controller 202, a first push-pull circuit 204, and a second push-pull circuit 206. The control terminals of both the first and second push-pull circuits 204 and 206 are connected to the controller 202. The output terminal of the first push-pull circuit 204 is connected to either the first or second terminal of the communication device 102, and the output terminal of the second push-pull circuit 206 is connected to either the second or first terminal of the communication device 102. The controller 202 can control the on / off state of the heating control switch Q5 by controlling the operating states of the first and second push-pull circuits 204 and 206, thereby controlling whether the heating element 104 heats up. This ensures that the heating element 104 does not heat up during signal transmission with the heating circuit 100, improving the reliability of the heating circuit 100.

[0062] Exemplarily, in one embodiment, such as Figure 4 As shown, the heating control circuit 200 also includes a demodulation circuit 208, and the controller 202 is connected to the output terminal of the first push-pull circuit 204 through the demodulation circuit 208. Figure 4 Only the case where the heating circuit 100 and the heating control circuit 200 are connected in the correct orientation is shown.

[0063] The input terminal of the demodulation circuit 208 is connected to the output terminal of the first push-pull circuit 204, which in turn connects to the communication device 102 of the heating circuit 100. The output terminal of the demodulation circuit 208 is connected to the controller 202. After the signal transmitted by the communication device 102 reaches the demodulation circuit 208, the demodulation circuit 208 performs demodulation and shaping processing on the signal, and then transmits the processed signal to the controller 202, enabling the controller 202 to recognize the signal transmitted from the communication device 102. The structure of the demodulation circuit 208 is not unique; for example, the demodulation circuit 208 can be a demodulation chip, which integrates multiple functions and can improve the performance of the heating control circuit 200.

[0064] In this embodiment, the heating control circuit 200 further includes a demodulation circuit 208, and the controller 202 is connected to the output terminal of the first push-pull circuit 204 through the demodulation circuit 208. The demodulation circuit 208 can process the signal from the communication device 102, obtain a signal that can be recognized by the controller 202, and then transmit it to the controller 202, which helps to improve the effectiveness and accuracy of the signal transmitted between the heating control circuit 200 and the heating circuit 100.

[0065] Furthermore, in one embodiment, the first push-pull circuit 204 and the second push-pull circuit 206 have identical structures. This means that the types and numbers of components in the first push-pull circuit 204 and the second push-pull circuit 206 are the same, and the connection relationships between these components are also identical. The identical structures of the first push-pull circuit 204 and the second push-pull circuit 206 improve the symmetry of the heating control circuit 200 structure and also minimize the voltage difference between the first push-pull circuit 204 and the second push-pull circuit 206 when switching between different operating states. This helps ensure the performance of the communication device 102, the heating control switch Q5, and the heating element 104.

[0066] Exemplarily, in one embodiment, such as Figure 5As shown, the first push-pull circuit 204 includes a first switch Q3 and a second switch Q4 with opposite polarities, and the second push-pull circuit 206 includes a third switch Q6 and a fourth switch Q7 with opposite polarities. The control terminals of both the first and second switches Q3 and Q4 are connected to the controller 202. The first terminal of the first switch Q3 is connected to a power source, and its second terminal is connected to the second terminal of the second switch Q4, serving as the output terminal of the first push-pull circuit 204. The first terminal of the second switch Q4 is grounded. Similarly, the control terminals of the third and fourth switches Q6 and Q7 are connected to the controller 202. The first terminal of the third switch Q6 is connected to a power source, and its second terminal is connected to the second terminal of the fourth switch Q7, serving as the output terminal of the second push-pull circuit 206. The first terminal of the third switch Q6 is grounded.

[0067] The controller 202 is connected to the control terminals of the first switch Q3, the second switch Q4, the third switch Q6, and the fourth switch Q7. It controls the operating states of these switches by sending signals to them. The first and second switches Q3 and Q4 do not conduct simultaneously, nor do the third and fourth switches Q6 and Q7. Furthermore, the controller 202 can be connected to different ports to the control terminals of these switches, ensuring that the signals sent to their control terminals are independent and that their operating states do not affect each other, allowing for more possible combinations.

[0068] Furthermore, the first switch Q3 and the third switch Q6 have the same polarity, and the second switch Q4 and the fourth switch Q7 have the same structure to improve the symmetry of the first push-pull circuit 204 and the second push-pull circuit 206. The first switch Q3, the second switch Q4, the third switch Q6, and the fourth switch Q7 are not unique; for example, the first switch Q3 and the third switch Q6 can be PMOS transistors, and the second switch Q4 and the fourth switch Q7 can be NMOS transistors.

[0069] For example, when the first switch Q3 and the fourth switch Q7 are turned on, and the second switch Q4 and the third switch Q6 are turned off, the voltage at the control terminal of the heating control switch Q5 is pulled low. Taking the heating control switch Q5 as an NMOS transistor, the NMOS transistor is turned off at this time, and the heating element 104 does not heat up. When the first switch Q3 and the fourth switch Q7 are turned off, and the second switch Q4 and the third switch Q6 are turned on, there is a voltage drop in the heating element 104, and the voltage at the control terminal of the heating control switch Q5 is greater than the voltage at the first terminal of the heating control switch Q5. Taking the heating control switch Q5 as an NMOS transistor, the NMOS transistor is turned on at this time, and the heating element 104 heats up.

[0070] In this embodiment, the first push-pull circuit 204 includes a first switch Q3 and a second switch Q4 with opposite polarities, and the second push-pull circuit 206 includes a third switch Q6 and a fourth switch Q7 with opposite polarities. The voltage control of the first terminal of the communication device 102 is achieved through the coordinated operation of the first switch Q3 and the second switch Q4, and the voltage control of the second terminal of the communication device 102 is achieved through the coordinated operation of the third switch Q6 and the fourth switch Q7. This enables the control of the conduction state of the heating control switch Q5 and the control of the working state of the heating element 104. The structure is simple and the control is convenient.

[0071] Exemplarily, in one embodiment, such as Figure 6 As shown, the heating control circuit 200 also includes a first control switch Q8 and a second control switch Q9. The control terminals of the first control switch Q8 and the second control switch Q9 are both connected to the controller 202. The first terminal of the first control switch Q8 is connected to the output terminal of the first push-pull circuit 204. The second terminal of the first control switch Q8 is connected to the second terminal of the second control switch Q9 and is also connected to the end of the demodulation circuit 208 away from the controller 202. The first terminal of the second control switch Q9 is connected to the output terminal of the second push-pull circuit 206.

[0072] The controller 202 is connected to the control terminals of the first control switch Q8 and the second control switch Q9, and is used to control the operating states of the first control switch Q8 and the second control switch Q9 by sending signals to their respective control terminals. Furthermore, the controller 202 can be connected to the control terminals of the first control switch Q8 and the second control switch Q9 through different ports, so that the signals sent to the first control switch Q8 and the second control switch Q9 are independent of each other, ensuring that the operating states of the first control switch Q8 and the second control switch Q9 do not affect each other, allowing for more possible combinations.

[0073] By controlling the conduction states of the first control switch Q8 and the second control switch Q9, the conduction state between the communication device 102 and the demodulation circuit 208 can be controlled. Furthermore, when the communication device 102 is positively connected, the conduction state between the first terminal of the communication device 102 and the demodulation circuit 208 can be controlled by controlling the conduction state of the first control switch Q8. When the communication device 102 is positively connected, if the first control switch Q8 is on, the first terminal of the communication device 102 is connected to the demodulation circuit 208, and the signal output by the communication device 102 can be transmitted to the demodulation circuit 208 through the on-state first control switch Q8.

[0074] When the communication device 102 is reverse-connected, the conduction state between the first terminal of the communication device 102 and the demodulation circuit 208 can be controlled by controlling the conduction state of the second control switch Q9. When the communication device 102 is reverse-connected, if the second control switch Q9 is on, the first terminal of the communication device 102 is connected to the demodulation circuit 208, and the signal output by the communication device 102 can be transmitted to the demodulation circuit 208 through the on-state second control switch Q9.

[0075] In this embodiment, the heating control circuit 200 further includes a first control switch Q8 and a second control switch Q9. The control terminals of both the first and second control switches Q8 and Q9 are connected to the controller 202. The first terminal of the first control switch Q8 is connected to the output terminal of the first push-pull circuit 204, and the second terminal of the first control switch Q8 is connected to the second terminal of the second control switch Q9 and to the end of the demodulation circuit 208 furthest from the controller 202. The first terminal of the second control switch Q9 is connected to the output terminal of the second push-pull circuit 206. By controlling the conduction states of the first and second control switches Q8 and Q9, the conduction state between the communication device 102 and the demodulation circuit 208 can be controlled whether the heating circuit 100 is connected in the forward or reverse direction, which helps improve the performance of the heating control circuit 200.

[0076] Exemplarily, in one embodiment, such as Figure 6 As shown, the heating control circuit 200 also includes a pull-up resistor R. The first end of the pull-up resistor R is used to connect to the power supply, and the second end of the pull-up resistor R is connected to the controller 202 and the output terminal of the second push-pull circuit 206.

[0077] Alternatively, in one embodiment, the heating control circuit 200 further includes a pull-up resistor R, the first end of which is connected to a power source, and the second end of which is connected to the controller 202 and the output of the first push-pull circuit 204.

[0078] The second end of the pull-up resistor R is connected to the controller 202, specifically to the sampling port of the controller 202, so that the sampling port of the controller 202 can obtain the voltage at the second end of the pull-up resistor R. When the heating circuit 100 is connected in the correct orientation and in the reverse orientation, the conducting devices of the heating circuit 100 and the heating control circuit 200 are different, and therefore the devices connected to the pull-up resistor R are also different, resulting in different voltages at the second end of the pull-up resistor R. Thus, the controller 202 can identify whether the heating circuit 100 is connected in the correct orientation, in the reverse orientation, or not connected based on the voltage at the second end of the pull-up resistor R. The specific resistance value of the pull-up resistor R is not limited and can be determined according to actual needs. For example, the resistance value of the pull-up resistor R can be 1 megohm.

[0079] For example, with controller 202 controlling the second switch Q4 to conduct, heating circuit 100 and heating control circuit 200 are connected in the positive direction. The second end of pull-up resistor R is connected to the output terminal of controller 202 and the second push-pull circuit 206. Taking heating control switch Q5 as an NMOS transistor as an example, due to the presence of pull-up resistor R, the gate voltage of heating control switch Q5 is higher than the source voltage, so heating control switch Q5 conducts. At this time, the voltage at the second end of pull-up resistor R is equal to the voltage division between pull-up resistor R and heating element 104. Controller 202 can obtain this voltage value and identify that heating circuit 100 is connected in the positive direction. When heating circuit 100 is reversed, the gate voltage of heating control switch Q5 is pulled low and it does not conduct. At this time, the voltage at the second end of pull-up resistor R is equal to the voltage division between pull-up resistor R and the equivalent resistance of communication device 102. Controller 202 can obtain this voltage value and identify that heating circuit 100 is connected in the reverse direction. When the heating circuit 100 is not connected, the voltage at the second end of the pull-up resistor R is the connected power supply voltage. The controller 202 can obtain the voltage value at this point and identify that the heating circuit 100 is not connected.

[0080] In this embodiment, the heating control circuit 200 further includes a pull-up resistor R. The first end of the pull-up resistor R is used to connect to the power supply, and the second end of the pull-up resistor R is connected to the controller 202 and to the output terminal of the first push-pull circuit 204 or the output terminal of the second push-pull circuit 206. The controller 202 can determine the connection status of the heating circuit 100 by the voltage at the second end of the pull-up resistor R, and realize positive and negative connection identification through circuit design, thereby eliminating the need for specific hardware structures for foolproofing.

[0081] Further, in one embodiment, the control terminals of the first control switch Q8 and the second switch Q4 are connected to the same port of the controller 202, and the control terminals of the second control switch Q9 and the fourth switch Q7 are connected to the same port of the controller 202. Thus, the control terminals of the first control switch Q8 and the second switch Q4 receive the same signal from the controller 202, and when the control terminals of the first control switch Q8 and the second switch Q4 are of the same type, their conduction states are the same. The control terminals of the second control switch Q9 and the fourth switch Q7 are connected to the same port of the controller 202. Thus, the control terminals of the second control switch Q9 and the fourth switch Q7 receive the same signal from the controller 202, and when the control terminals of the second control switch Q9 and the fourth switch Q7 are of the same type, their conduction states are the same.

[0082] In this embodiment, the control terminals of the first control switch Q8 and the second switch Q4 are connected to the same port of the controller 202, and the control terminals of the second control switch Q9 and the fourth switch Q7 are connected to the same port of the controller 202. By sharing a port between the first control switch Q8 and the second switch Q4, and between the second control switch Q9 and the fourth switch Q7, port resources of the controller 202 can be saved.

[0083] To better understand the above embodiments, a specific embodiment will be provided for detailed explanation below. In one embodiment, an electronic atomizing device is provided, such as... Figure 7 As shown, it includes an atomizing device body 10 and an atomizer 20. The atomizing device body is provided with a heating control circuit 200, and the atomizer is provided with a heating circuit 100.

[0084] The heating circuit 100 includes a communication device 102, a heating control switch Q5, and a heating element 104. The communication device 102 is an anti-counterfeiting chip, the heating control switch Q5 is an NMOS transistor, and the heating element 104 is a heating wire. The heating control circuit 200 includes a controller 202, a first push-pull circuit 204, a second push-pull circuit 206, and a demodulation circuit 208. The first push-pull circuit 204 includes a first switch Q3 and a second switch Q4 with opposite polarities. The second push-pull circuit 206 includes a third switch Q6 and a fourth switch Q7 with opposite polarities. The controller 202 is an MCU.

[0085] Specifically, the atomizer retains the parallel design of the anti-counterfeiting chip. An NMOS transistor is connected in series at the top of the heating wire, with its gate connected to the bottom of the heating wire, its source connected to the top of the heating wire, and its drain connected to the top of the anti-counterfeiting chip. The bottom of the anti-counterfeiting chip is connected to the bottom of the heating wire. A matching heating control circuit 200 is provided in the atomizer body. Two push-pull circuits are added to the atomizer body, with their outputs connected to the pins at both ends. The demodulation circuit 208 is connected to the top pin.

[0086] When the MCU wants to send a signal, it controls Q3 and Q7 to turn on and Q4 and Q6 to turn off. At this time, Q5 is turned off because its gate is pulled low. The MCU sends the signal by controlling the on and off of Q3 or Q7.

[0087] When the anti-counterfeiting chip needs to return a signal, it can send a signal sending request command to the MCU. After receiving the signal sending request command, the MCU controls Q3 and Q7 to turn on and Q4 and Q6 to turn off. At this time, Q5 is turned off because its gate is pulled low. The anti-counterfeiting chip causes voltage fluctuations through its own circuit (including but not limited to a constant current source), which are then shaped by the demodulation circuit 208 and input to the MCU.

[0088] When heating and atomization are needed, the MCU controls Q4 and Q6 to turn on and Q3 and Q7 to turn off. At this time, because there is a voltage drop in the heating wire, the gate voltage of Q5 is higher than the source voltage, so Q5 turns on and the heating wire heats normally.

[0089] In this embodiment, the electronic atomizing device eliminates the risk of the heating wire heating simultaneously during communication. However, the atomizer needs to be reversible, requiring a foolproof design in its structure.

[0090] Furthermore, in one embodiment, such as Figure 8 and Figure 9 As shown, the heating control circuit 200 also includes a first control switch Q8, a second control switch Q9, and a pull-up resistor R.

[0091] Specifically, the drains of Q8 and Q9 are connected to the input terminal of the demodulation circuit 208, the sources of Q8 and Q9 are connected to the pins at the top and bottom ends of the atomizing device body, the gate of Q8 is connected to the gate of Q4, and the gate of Q9 is connected to the gate of Q7.

[0092] Accordingly, the atomizer body needs to identify whether the atomizer is inserted correctly or incorrectly in order to match the corresponding control logic. Generally, this can be achieved by connecting a 1-megohm pull-up resistor R to either the connection point of the atomizer body or the atomizer. One end of the pull-up resistor R is connected to the power supply, and the other end is connected to any pin and the ADC channel of the MCU.

[0093] When identifying the correct orientation of the atomizer insertion, the corresponding MOSFET needs to be turned on (according to...). Figure 8For the correct connection method, Q4 needs to be controlled to conduct. When the atomizer is inserted correctly, due to the pull-up resistor R, the gate voltage of Q5 is higher than the source voltage, so Q5 conducts. At this time, the voltage at this terminal is equal to the voltage division of 1 megohm and the heating coil. The MCU can obtain the voltage value at this point through ADC sampling and identify that the atomizer is inserted correctly. When the atomizer is inserted incorrectly, the gate of Q5 is pulled low and does not conduct. At this time, the voltage at this terminal is equal to the voltage division of 1 megohm and the equivalent resistance (approximately 10K) of the anti-counterfeiting IC (anti-counterfeiting chip). The MCU can obtain the voltage value at this point through ADC sampling and identify that the atomizer is inserted incorrectly. When the atomizer is not inserted, the voltage at this terminal is the circuit's supply voltage. The MCU can obtain the voltage at this point through ADC sampling and identify that the atomizer is not inserted.

[0094] like Figure 8 As shown, when the atomizer is connected correctly (i.e., the heating circuit and the heating control circuit are connected correctly):

[0095] When the MCU wants to send a signal, it controls Q3, Q8, and Q7 to be turned on, and Q4, Q9, and Q6 to be turned off. At this time, Q5 is turned off because its gate is pulled low. The MCU sends the signal by controlling the on and off states of Q3 or Q7.

[0096] When the anti-counterfeiting chip needs to return a signal, the MCU controls Q3, Q8, and Q7 to turn on and Q4, Q9, and Q6 to turn off. At this time, Q5 is turned off because its gate is pulled low. The anti-counterfeiting chip causes voltage fluctuations through its own circuit (including but not limited to a constant current source), which are then shaped by the demodulation circuit 208 and input to the MCU.

[0097] When heating and atomization are required, the MCU controls Q4, Q9, and Q6 to turn on and Q3, Q8, and Q7 to turn off. At this time, because there is a voltage drop in the heating wire, the gate voltage of Q5 is higher than the source voltage, so Q5 turns on and the heating wire heats normally.

[0098] like Figure 9 As shown, when the atomizer is reversed (i.e., the heating circuit and heating control circuit are connected in reverse):

[0099] When the MCU wants to send a signal, it controls Q4, Q9, and Q6 to be turned on, and Q3, Q8, and Q7 to be turned off. At this time, Q5 is turned off because its gate is pulled low. The MCU sends the signal by controlling the on and off states of Q4 or Q6.

[0100] When the anti-counterfeiting chip needs to return a signal, the MCU controls Q4, Q9, and Q6 to turn on and Q3, Q8, and Q7 to turn off. At this time, Q5 is turned off because its gate is pulled low. The anti-counterfeiting chip causes voltage fluctuations through its own circuit (including but not limited to a constant current source), which are then shaped by the demodulation circuit 208 and input to the MCU.

[0101] When heating and atomization are required, the MCU controls Q3, Q8, and Q7 to turn on and Q4, Q9, and Q6 to turn off. At this time, because there is a voltage drop in the heating wire, the gate voltage of Q5 is higher than the source voltage, so Q5 turns on and the heating wire heats normally.

[0102] Based on the structure of this embodiment, the structure does not require foolproofing, and the atomizer can be inserted without distinguishing the direction, which improves the reliability of the electronic atomization device.
