TECHNICAL FIELD
[0001] The present application relates to the technical field of atomization, in particular to an electronic atomization device. BACKGROUND
[0002] An electronic atomization device is usually composed of an atomizer storing an aerosol generating substrate and a battery rod. In use, the atomizer is plugged into the battery rod, and the battery rod provides heating power for the atomizer to heat the aerosol generating substrate to convert it into an aerosol for use by a user. When the aerosol generating substrate in the atomizer is used up, the user can replace a new atomizer for continued use.
[0003] However, in recent years, a large number of counterfeit atomizer products have appeared on the market. These counterfeit products are highly similar to genuine products in terms of appearance design and interface specifications, making it difficult for ordinary users to distinguish between genuine and counterfeit products from appearance. To address this problem, manufacturers usually set anti-counterfeiting information in the atomizer, and the battery rod identifies whether the atomizer is a matching genuine product by reading the anti-counterfeiting information of the atomizer.
[0004] However, in related electronic atomization devices, the battery rod can only read the anti-counterfeiting information of the atomizer when the atomizer is correctly plugged into the battery rod in a specified connection manner (i.e., the atomizer is plugged in). If the user plugs the atomizer into the battery rod in a manner different from the specified connection manner (i.e., the atomizer is plugged in reversely), anti-counterfeiting identification cannot be performed. This requires the user to carefully confirm whether the insertion manner is correct before use, undoubtedly increasing the complexity of operation and resulting in low convenience of use of the electronic atomization device.

[0032] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.
[0033] In one embodiment, an electronic atomization device is provided. As shown in the figure, the electronic atomization device includes a battery rod 100 and an atomizer 200. Figure 1
[0034] The atomizer 200 includes a first heating assembly 221 and a second heating assembly 222. The two ends of the first heating assembly 221 are connected to a first connection end 211 and a second connection end 212, respectively. The two ends of the second heating assembly 222 are connected to a third connection end 213 and the second connection end 212, respectively.
[0035] It can be understood that in actual implementation, the atomizer 200 is also provided with a liquid storage cavity and an atomization cavity, and the liquid storage cavity is used to accommodate the aerosol generating substrate. When one of the first heating assembly 221 and the second heating assembly 222 is powered on, or both of the first heating assembly 221 and the second heating assembly 222 are powered on, the heat released by the heating assembly can atomize the aerosol generating substrate in the atomization cavity into aerosol.
[0036] Exemplarily, the first heating assembly 221 and the second heating assembly 222 can adopt a heating body, such as a heating wire. During the power-on process of the heating wire, the aerosol generating substrate is effectively atomized by means of resistance heating.
[0037] The atomizer 200 also includes a first connection end 211, a second connection end 212 and a third connection end 213. The first connection end 211, the second connection end 212 and the third connection end 213 are used to access the battery rod 100.
[0038] In the case where the first connection end 211, the second connection end 212 and the third connection end 213 access the battery rod 100, when the atomization function is implemented, the battery rod 100 can provide power to the first heating assembly 221 and the second heating assembly 222 through the first connection end 211, the second connection end 212 and the third connection end 213, so that the first heating assembly 221 and the second heating assembly 222 are powered on.
[0039] When the battery stick 100 is accessed, the power supply polarities of the first connection end 211 and the third connection end 213 are the same, and the power supply polarities of the second connection end 212 and the first connection end 211 are opposite, which can be set according to actual conditions. Exemplarily, the first connection end 211 and the third connection end 213 can be directly or indirectly (through other circuits such as a switch module) connected to the positive electrode end of the power supply of the battery stick 100, and the second connection end 212 is connected to the negative electrode end of the power supply of the battery stick 100. The first connection end 211 and the third connection end 213 can also be connected to the negative electrode end of the power supply of the battery stick 100, and the second connection end 212 is directly or indirectly connected to the positive electrode end of the power supply of the battery stick 100.
[0040] It can be understood that a battery is arranged in the battery stick 100, the positive electrode of the battery is connected to the positive electrode end of the power supply of the battery stick 100, and is used to provide a positive voltage to drive the heating assembly in the atomizer 200 and the like to work. The negative electrode of the battery is connected to the negative electrode end of the power supply, and is usually grounded to ensure the safety and stability of the circuit.
[0041] The atomizer 200 further comprises an anti-counterfeiting device 223, and the two ends of the anti-counterfeiting device 223 are respectively connected to the first connection end 211 and the third connection end 213.
[0042] When the battery stick 100 is connected to the atomizer 200, the battery stick 100 can output a verification signal (such as a signal with a specific waveform) to the atomizer 200, and the anti-counterfeiting device 223 returns a feedback signal (such as a signal with a specific waveform) to the battery stick 100 after receiving the verification signal. The battery stick 100 judges whether the atomizer 200 is matched according to the feedback signal, so as to realize anti-counterfeiting identification.
[0043] The specific scene of the battery stick 100 outputting a verification signal to the atomizer 200 for anti-counterfeiting identification does not need to be limited. For example, the battery stick 100 can output a verification signal for anti-counterfeiting identification when detecting that a new atomizer 200 is connected, or the user can start the electronic atomization device (such as triggering a specified key, issuing a specified action, etc.) to perform anti-counterfeiting identification.
[0044] When the battery stick 100 outputs a verification signal to the atomizer 200, and receives a feedback signal returned by the atomizer 200, one of the first connection end 211 and the third connection end 213 and the second connection end 212 can be used.
[0045] In actual implementation, the battery stick 100 can comprise a first access end 111 and a second access end 112, so as to communicate with the atomizer 200 through the first access end 111 and the second access end 112.
[0046] The communication information between the battery rod 100 and the atomizer 200 can include the verification signal output by the battery rod 100 to the atomizer 200 and the feedback signal output by the atomizer 200. It can also include other signals output by the atomizer 200 or other signals returned by the atomizer 200, such as the aerosol generating substrate remaining amount inquiry signal output by the battery rod 100 to the atomizer 200, the remaining amount information returned by the atomizer 200, and the like.
[0047] When the atomizer 200 is connected to the battery rod 100, the first connection end 211 or the third connection end 213 of the atomizer 200 is connected to the first access end 111, and the second connection end 212 is connected to the second access end 112.
[0048] When the anti-counterfeiting identification function is implemented, the battery rod 100 outputs the verification signal to the atomizer 200 through the first access end 111 and the second access end 112. In the case where the first connection end 211 is connected to the first access end 111 and the second connection end 212 is connected to the second access end 112, the anti-counterfeiting device 223 is connected in series between the first connection end 211 and the second connection end 212 with the second heating assembly 222. Since the resistance of the anti-counterfeiting device 223 is much larger than the resistance of the second heating assembly 222, the voltage drop of the verification signal is basically at both ends of the anti-counterfeiting device 223, so that the anti-counterfeiting device 223 can effectively receive the verification signal. Further, the anti-counterfeiting device 223 can cause a specific waveform voltage drop between the first connection end 211 and the second connection end 212, so that the battery rod 100 receives the feedback signal through the first access end 111 and the second access end 112.
[0049] In the case where the first connection end 211 is connected to the third connection end 213 and the second connection end 212 is connected to the second access end 112, the anti-counterfeiting device 223 is connected in series between the third connection end 213 and the second connection end 212 with the first heating assembly 221 to receive the verification signal. Further, the anti-counterfeiting device 223 can cause a specific waveform voltage drop between the third connection end 213 and the second connection end 212, so that the battery rod 100 receives the feedback signal through the first access end 111 and the second access end 112.
[0050] It can be understood that in the battery rod 100, the first access end 111 and the second access end 112 are arranged in specified positions. Correspondingly, in the atomizer 200, the first connection end 211, the second connection end 212 and the third connection end 213 are also arranged in specified positions. When the atomizer 200 is accessed to the battery rod 100, the second connection end 212 is docked with the second access end 112, and any one of the first connection end 211 and the third connection end 213 is docked with the first access end 111, which can achieve effective electrical connection and anti-counterfeiting identification function. Therefore, the user does not need to worry about the insertion direction when accessing the atomizer 200 to the battery rod 100, and does not need to identify and distinguish the positive and negative insertion, thereby simplifying the operation steps.
[0051] The above-mentioned electronic atomization device includes the battery rod 100 and the atomizer 200, wherein the atomizer 200 includes the first connection end 211, the second connection end 212, the third connection end 213, the first heating assembly 221, the second heating assembly 222 and the anti-counterfeiting device 223. The two ends of the first heating assembly 221 are respectively connected with the first connection end 211 and the second connection end 212; the two ends of the second heating assembly 222 are respectively connected with the third connection end 213 and the second connection end 212; the two ends of the anti-counterfeiting device 223 are respectively connected with the first connection end 211 and the third connection end 213. The battery rod 100 includes the first access end 111 and the second access end 112; the first access end 111 is used for connecting the first connection end 211 or the third connection end 213; the second access end 112 is connected with the negative electrode end of the power supply and is also used for connecting the second connection end 212. The battery rod 100 communicates with the atomizer 200 through the first access end 111 and the second access end 112. Therefore, when the user uses the electronic atomization device, whether the first connection end 211 or the third connection end 213 is connected to the specified connection end (i.e. the first access end 111) of the battery rod 100, the battery rod 100 can communicate with the anti-counterfeiting device 223 to read the information of the anti-counterfeiting device 223, thereby achieving anti-counterfeiting identification. Therefore, the user does not need to distinguish the positive insertion and the negative insertion again, thereby simplifying the operation process and improving the use convenience of the electronic atomization device.
[0052] In actual implementation, the anti-counterfeiting device 223 can be an anti-counterfeiting chip. The anti-counterfeiting chip has high integration and high stability, and occupies small volume, which is more conducive to the design of small and exquisite atomizer 200.
[0053] In one embodiment, as shown in Figure 2 the battery rod 100 further includes a first switch module 121. The first end of the first switch module 121 is accessed to the positive electrode end of the power supply, and the second end of the first switch module 121 is connected with the first access end 111.
[0054] When the first switch module 121 is in the on state, the power provided by the positive electrode end of the power supply can be provided to the atomizer 200 through the first switch module 121. When the first switch module 121 is in the off state, it can cut off the power supply of the atomizer 200 to prevent possible safety hazards and save power.
[0055] The battery rod 100 further comprises a controller 122. The controller 122 is connected to the controlled end of the first switch module 121.
[0056] When it is necessary to realize the anti-counterfeiting identification function, the controller 122 is configured to control the switching state of the first switch module 121 to generate a verification signal, and the verification signal is transmitted to the anti-counterfeiting device 223 through the first access end 111 and the first connection end 211.
[0057] The verification signal is a signal with a specific waveform set based on the anti-counterfeiting device 223. The process of the controller 122 controlling the switching state of the first switch module 121 to generate the verification signal can be combined with the specific waveform setting of the verification signal, which is not limited in the embodiment.
[0058] It can be understood that when the atomizer 200 needs to realize the atomization function, the controller 122 will also control the switching state of the first switch module 121 to provide stable power for the heating assembly in the atomizer 200.
[0059] The battery rod 100 further comprises a demodulation circuit 123. The demodulation circuit 123 is connected to the controller 122 and the first access end 111, respectively.
[0060] The demodulation circuit 123 is configured to demodulate the received feedback signal and transmit the demodulated feedback signal to the controller 122, and the controller 122 determines whether the atomizer 200 is matched according to the demodulated feedback signal. The feedback signal is a signal transmitted by the anti-counterfeiting device 223 according to the verification signal.
[0061] The demodulation circuit 123 can convert the feedback signal with a specific waveform received by the first access end 111 into a signal that can be recognized by the controller 122, so that the controller 122 can more efficiently process the feedback signal and realize rapid matching judgment of the atomizer 200.
[0062] The demodulation circuit 123 can be set according to specific conditions. In one embodiment, the demodulation circuit 123 comprises an amplifier and a comparator; the input end of the amplifier is connected to the first access end 111, the output end of the amplifier is connected to the input end of the comparator, and the output end of the comparator is connected to the controller 122.
[0063] The amplifier is configured to amplify the received feedback signal and transmit it to the comparator; the comparator is configured to shape the amplified feedback signal, and the shaping result is transmitted to the controller as a demodulation result.
[0064] In a specific implementation, the amplifier can be a same-phase proportional amplifier or other amplification circuit. The comparison threshold of the comparator can be set according to specific conditions.
[0065] In this embodiment, the amplifier can enhance the strength of the feedback signal, provide a clear signal source for subsequent comparator processing, and thus improve the reliability of the shaping result. The comparator performs threshold comparison on the amplified feedback signal, shapes the feedback signal to meet the recognition and processing requirements of the controller 122, so that the controller 122 can quickly identify whether the atomizer 200 is matched.
[0066] In other embodiments, the demodulation circuit 123 can use a professional decoding chip, and the model of the decoding chip does not need to be limited, and a person skilled in the art can select it according to specific conditions.
[0067] In one embodiment, as shown in Figure 3 The third access end 113 is used to connect one of the third connection end 213 and the first connection end 211. The one of the third connection end 213 and the first connection end 211, which is not connected with the third access end 113, is used to connect the first access end 111.
[0068] It can be understood that when the atomizer 200 is connected to the battery rod 100, the first connection end 211 can be connected to the first access end 111, the second connection end 212 can be connected to the second access end 112, and the third connection end 213 can be connected to the third access end 113. Alternatively, the first connection end 211 can be connected to the third access end 113, the second connection end 212 can be connected to the second access end 112, and the third connection end 213 can be connected to the first access end 111.
[0069] When the atomization function is implemented, the third connection end 213 is used to provide electric energy. Thus, the first connection end 211 and the third connection end 213 can provide electric energy to the first heating assembly 221 and the second heating assembly 222, respectively.
[0070] It can be understood that when the anti-counterfeiting identification function is implemented, the third connection end 213 stops providing electric energy, so as to avoid the electric energy of the third connection end 213 from interfering with the signal between the first connection end 211 and the second connection end 212.
[0071] The battery rod 100 further includes a second switch module 124. A first end of the second switch module 124 is connected to the positive electrode end of the power supply, a controlled end of the second switch module 124 is connected to the controller 122, and a second end of the second switch module 124 is connected to the third access end 113.
[0072] Thus, the controller 122 can control the switching state of the second switch module 124 to provide or stop providing electric energy to the third access end 113, thereby providing power to the atomizer 200 or disconnecting the power supply of the atomizer 200. Thus, by providing the second switch module 124, reliable control of the power supply state of the third access end 113 can be achieved.
[0073] In actual application, when the atomization function is implemented, the controller 122 can control the switching state of the first switch module 121 and the second switch module 124 to provide atomization electric energy to the atomizer 200.
[0074] When providing atomization electric energy to the atomizer 200, the controller 122 can control the first switch module 121 and the second switch module 124 to be conductive at the same time, or control the first switch module 121 and the second switch module 124 to be conductive alternately. The specific control mode can be set according to the structure of the atomization cavity, the characteristics of the aerosol generating substrate, and other specific conditions, which are not limited in the present embodiment.
[0075] Since the resistance of the anti-counterfeiting device 223 is very large, during the power-on working process of the first heating assembly 221 and the second heating assembly 222, the anti-counterfeiting device 223 is equivalent to an open circuit state, and thus will not affect the heating effect of the first heating assembly 221 and the second heating assembly 222.
[0076] In some embodiments, the controller 122 is further configured to control the first switch module 121 to be conductive and the second switch module 124 to be disconnected, so as to send a verification signal to the anti-counterfeiting device 223 through the first switch module 121, and receive a feedback signal sent by the anti-counterfeiting device 223 through the first switch module 121.
[0077] The controller 122 determines whether the atomizer 200 is matched according to the feedback signal, thereby achieving anti-counterfeiting identification. When the anti-counterfeiting identification function is implemented, by controlling the second switch module 124 to be in a disconnected state, the electric energy of the third connection end 213 can be avoided to interfere with the anti-counterfeiting identification result.
[0078] The circuit structure of the first switch module 121 and the second switch module 124 can be set according to specific conditions. In one embodiment, as shown in Figure 4 The first switch module 121 includes a first switch tube Q1. The first end of the first switch tube Q1 is connected to the positive electrode end of the power supply, the controlled end of the first switch tube Q1 is connected to the controller 122, and the second end of the first switch tube Q1 is connected to the first access end 111.
[0079] In the embodiment, the first switch tube Q1 is connected between the positive terminal of the power supply and the first access terminal 111 and is controlled by the controller 122. When the first switch tube Q1 is turned on, the first access terminal 111 receives the authentication signal or the atomization power; when the first switch tube Q1 is turned off, the first access terminal 111 stops receiving the authentication signal or the atomization power.
[0080] The type of the first switch tube Q1 is not limited and can be a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) tube or a transistor that can be used for switch control. The first end, the second end and the controlled end of the first switch tube Q1 are set according to the type thereof. For example, the first switch tube Q1 is a PMOS tube, the gate thereof is the controlled end, the source thereof is the first end, and the drain thereof is the second end.
[0081] Since the first switch tube Q1 has reliable turn-on and turn-off capabilities and the circuit structure thereof is simple, the first switch tube Q1 is selected in the first switch module 121, the voltage state of the first access terminal 111 can be reliably controlled, and the entire module occupies a small volume, thereby facilitating the miniaturization of the battery rod 100.
[0082] Further, in some embodiments, the first switch module 121 can further include a first resistor R1; the first end of the first resistor R1 is connected to the first end of the first switch tube Q1, and the second end of the first resistor R1 is connected to the controlled end of the first switch tube Q1.
[0083] The first resistor R1 serves as a pull-up resistor and can provide a determined high level for the controlled end of the first switch tube Q1, so that the turn-on or turn-off state of the first switch tube Q1 is more stable, thereby improving the reliability and stability of the circuit.
[0084] In one embodiment, the second switch module 124 can include a second switch tube Q2; the first end of the second switch tube Q2 is connected to the positive terminal of the power supply, the controlled end of the second switch tube Q2 is connected to the controller 122, and the second end of the second switch tube Q2 is connected to the third access terminal 113.
[0085] In the embodiment, the second switch tube Q2 is connected between the positive terminal of the power supply and the third access terminal 113 and is controlled by the controller 122. When the second switch tube Q2 is turned on, the third access terminal 113 receives the atomization power; when the second switch tube Q2 is turned off, the third access terminal 113 stops receiving the atomization power.
[0086] The type of the second switch tube Q2 is not limited, and can be a MOS tube or a transistor capable of being used for switch control. The first end, the second end and the controlled end of the second switch tube Q2 need to be set according to the type. For example, the second switch tube Q2 is a PMOS tube, the gate thereof is the controlled end, the source thereof is the first end, and the drain thereof is the second end.
[0087] Since the second switch tube Q2 has reliable conduction and turn-off capabilities, and the circuit structure thereof is simple, the second switch tube Q2 is selected in the second switch module 124, so that the voltage state of the third connection end 113 can be reliably controlled, and the entire module occupies a small volume, thereby facilitating the miniaturization of the battery rod 100.
[0088] Further, in some embodiments, the second switch module 124 can further include a second resistor R2; the first end of the second resistor R2 is connected to the first end of the second switch tube Q2, and the second end of the second resistor R2 is connected to the controlled end of the second switch tube Q2.
[0089] The second resistor R2 serves as a pull-up resistor, and can provide a determined high level for the controlled end of the second switch tube Q2, so that the conduction or turn-off state of the second switch tube Q2 is more stable, thereby improving the reliability and stability of the circuit.
[0090] In order to better understand the above embodiments, the following detailed explanation is made in combination with the embodiments. Figure 4 In an optional embodiment, the electronic atomization device 10 includes a battery rod 100 and an atomizer 200.
[0091] The atomizer 200 includes a first connection end 211, a second connection end 212, a third connection end 213, a first heating assembly 221, a second heating assembly 222 and an anti-counterfeiting device 223. The two ends of the first heating assembly 221 are respectively connected to the first connection end 211 and the second connection end 212, the two ends of the second heating assembly 222 are respectively connected to the third connection end 213 and the second connection end 212, and the two ends of the anti-counterfeiting device 223 are respectively connected to the first connection end 211 and the third connection end 213.
[0092] The anti-counterfeiting device 223 can be an anti-counterfeiting chip. For example, the anti-counterfeiting chip is an AES128NEMC, which can return a specific waveform signal after receiving a specific waveform signal at both ends. The resistance of the anti-counterfeiting chip is about 10KΩ (ohm). The first heating assembly 221 and the second heating assembly 222 can both be heating bodies, and the resistance of the heating bodies is about 1Ω.
[0093] The battery rod 100 comprises a first access end 111, a second access end 112, a third access end 113, a first switch module 121, a second switch module 124, a demodulation circuit 123 and a controller 122. The controller 122 can be an MCU (MicroController Unit). The first switch module 121 comprises a first switch tube Q1 and a first resistor R1. The first end of the first switch tube Q1 is connected to the positive terminal of the power supply, the second end is connected to the first access end 111, and the controlled end is connected to the controller 122. The second switch module 124 comprises a second switch tube Q2 and a second resistor R2. The first end of the second switch tube Q2 is connected to the positive terminal of the power supply, the second end is connected to the third access end 113, and the controlled end is connected to the controller 122. The demodulation circuit 123 is connected to the first access end 111 and the controller 122 respectively.
[0094] In actual implementation, the electronic atomization device can further comprise a needle. The first connection end 211, the second connection end 212 and the third connection end 213 are all connected to the battery rod 100 through the needle.
[0095] After the atomizer 200 is connected to the battery rod 100, the first connection end 211 is connected to the first access end 111 through the needle, the second connection end 212 is connected to the second access end 112 through the needle, and the third connection end 213 is connected to the third access end 113 through the needle. After the above connection, the electronic atomization device can at least realize the anti-counterfeiting identification function and the atomization function.
[0096] In the implementation of the anti-counterfeiting identification function, the battery rod 100 needs to communicate with the atomizer 200. At this time, the controller 122 transmits the verification signal to the anti-counterfeiting chip (illustrated as an anti-counterfeiting IC) by controlling the conduction of the first switch tube Q1, while controlling the second switch tube Q2 to be in an open state. At this time, the equivalent circuit is that the anti-counterfeiting chip is connected in series with one of the heating bodies and then connected in parallel with the other heating body. Since the equivalent resistance of the anti-counterfeiting chip is about 10KΩ when receiving signals, the voltage drop across the anti-counterfeiting chip is basically when the heating body (with a resistance of about 1Ω) is connected in series, so it does not affect the anti-counterfeiting chip to receive signals. When the anti-counterfeiting chip wants to return a signal, the controller 122 controls the first switch tube Q1 to be conductive, and the anti-counterfeiting chip makes the voltage of the first connection end 211 fluctuate through its own circuit (including but not limited to a constant current source). After being amplified and shaped by the demodulation circuit 123, it is input to the controller 122. Since the resistance of the heating body is small, its influence on the two ends of the anti-counterfeiting chip can be ignored, and it does not affect the communication.
[0097] Further, the controller 122 judges whether the atomizer 200 is a matching genuine product according to the received shaped signal. In this way, the anti-counterfeiting detection of the double-heating-body atomizer 200 is realized.
[0098] When the controller 122 detects that the atomizer 200 is a non-matching counterfeit product, it can take corresponding measures, such as issuing a reminder signal to remind the user, or controlling the first switch tube Q1 and the second switch tube Q2 to be in an off state continuously, to stop outputting power to the atomizer 200, preventing the counterfeit product from causing potential harm to the user during use, thereby improving the use safety of the electronic atomization device.
[0099] When implementing the atomization function, the controller 122 controls the conduction state of the first switch tube Q1 and the second switch tube Q2 to supply power to the two heating bodies in the atomizer 200, so that the two heating bodies heat up, heat the aerosol generating substrate in the atomization cavity, and atomize it into an aerosol.
[0100] The above electronic atomization device realizes anti-counterfeiting detection of the double-heating-body atomizer 200, thereby improving the use safety of the electronic atomization device. Moreover, the user does not need to distinguish between normal insertion and reverse insertion, the operation process is simple, and the electronic atomization device is convenient to use.
