Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to a power control circuit and a method for changing an electronic cigarette system using a transmitting device. Background Art

[0002] E-cigarettes are non-combustion cigarettes that offer similar benefits to traditional burning cigarettes, helping users experience a sense of euphoria and relaxation. Compared to traditional burning cigarettes, they also have a relatively minimal impact on the health of others and the user themselves, leading to their widespread adoption and rapid growth.

[0003] Due to cost constraints, current e-cigarette products on the market typically use OTP (One Time Programmable) chips, meaning they can only be programmed once, preventing future modifications to the product parameters. If e-cigarette product parameters, such as output voltage and operating power, fail to meet user requirements, the device must be disassembled and the internal chip replaced, resulting in wasted time and material losses. Summary of the Invention

[0014] Optionally, in the process of determining the power control information according to the signal sampling sequence, the main control chip sequentially determines whether each bit of the boot code meets the preset digital password. If they all meet, the confirmation adjustment code is changed; otherwise, the power adjustment operation is terminated.

[0015] Optionally, the atomizer core has multiple power output gears, and the target power value corresponds to each power output gear. When the atomizer core adjusts the working power of the electronic cigarette in response to the power control signal, the power output gear is determined according to the target power value.

[0016] Optionally, the atomizer core has multiple power output gears, and the target power value corresponds to each power output gear. When the atomizer core adjusts the working power of the electronic cigarette in response to the power control signal, the power output gear is determined according to the target power value.

[0019] In a second aspect, the present application also provides a method for changing an electronic cigarette system using a transmitting device, comprising the following steps:

[0020] A transmitting device is provided for transmitting a charging pulse sequence, wherein the transmitting device has a transmitting interface;

[0021] An electronic cigarette is provided. The electronic cigarette is equipped with a main control chip, a charging interface, a current sampling circuit, and an atomization output port. The charging interface is connected to the voltage sampling circuit, the voltage sampling circuit is connected to the main control chip, and the main control chip is also connected to the atomization output port.

[0022] Connecting the transmitting interface to the charging interface, the charging interface receives the charging pulse sequence sent by the transmitting device, the charging pulse sequence including the guidance sequence and the correction sequence;

[0023] The current sampling circuit collects the guide sequence and the correction sequence, obtains the signal sampling sequence and sends it to the main control chip;

[0024] If the signal sampling sequence matches the information pre-stored in the main control chip, the main control chip starts to adjust the output power of the atomization output port; otherwise, the main control chip refuses to adjust the output power of the atomization output port.

[0041] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0042] It should be noted that, if there is no conflict, the various features in the embodiments of the present application can be combined with each other and are all within the scope of protection of the present application. In addition, although the functional modules are divided in the device schematic and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than the module division in the device or the order in the flow chart. Furthermore, the words "first", "second", "third", etc. used in this application do not limit the data and execution order, but only distinguish between the same items or similar items with basically the same functions and effects.

[0043] First, the application environment of the electronic cigarette power control method in the embodiment of the present application is introduced.

[0044] See also Figure 1 , Figure 1 Schematic diagram of the application environment of the electronic cigarette power control method provided in one embodiment of the present application. In this application environment, the electronic cigarette product 10 needs to change the operating power of its atomizer core due to the specific needs of the user, so that the electronic cigarette 10 can form different smoke effects based on the smoke liquid. In this process, an external signal transmitting device 20 is inserted into the charging port of the electronic cigarette 10 product to send a specific charging pulse sequence carrying power control information. The electronic cigarette 10 can change the operating power of the atomizer core according to the power control information carried by the charging pulse sequence, and then change the amount of smoke produced by the electronic cigarette 10, so that the operating power of the electronic cigarette meets the user's requirements.

[0045] See also Figure 2 , Figure 2This is a schematic diagram of the electronic cigarette architecture module provided in one embodiment of the present application. The electronic cigarette 20 includes a housing 21, an atomizer assembly 23, a control assembly 22, and a power supply assembly 24. The housing 21 serves as the supporting structure for the electronic cigarette 20, while the other components are housed within the housing to protect them. The atomizer assembly 23 includes an atomizer core, which heats the drawn-in e-liquid until it boils, atomizing the e-liquid to produce smoke flavor. The power supply assembly 24 includes a battery, which provides energy to the atomizer assembly for heating. The control assembly 22 includes a charging management chip and a main control chip. A charging circuit is externally provided on the charging management chip, which is connected to a charging port for connecting to an external power source to supply power to the power supply assembly. The charging management chip controls and regulates input voltage, current, and power. The charging circuit also includes a branch of a current sampling circuit, which is connected between the charging management chip and the main control chip. This circuit monitors the magnitude and frequency of the input current, voltage, and other factors to prevent excessive current or voltage from damaging internal components or overcharging the battery. The main control chip is the main control element of the electronic cigarette. Compared with the OTP chip in the prior art, the main control chip in this embodiment can not only control the start and shut down of the electronic cigarette, but also control and adjust the working power of the electronic cigarette atomization core. The main control chip is provided with a pin, which is connected to the current sampling circuit, for obtaining the charging status of the electronic cigarette and adjusting the power of the atomization core according to the power control information carried by the charging pulse sequence. In some embodiments, the customer of the electronic cigarette product is a foreign customer. During the stage of sending the electronic cigarette product for testing, the customer finds that the amount of smoke generated by the electronic cigarette is too large or too small due to inappropriate power. There is no need to re-burn the OTP chip in China to re-produce the electronic cigarette sample. It is only necessary to connect the electronic cigarette to a modulated power supply and send a specific charging pulse sequence carrying power control information to the electronic cigarette through the modulated power supply to modify the working power parameters of the electronic cigarette, so that the amount of smoke produced by the electronic cigarette meets the customer's requirements.

[0046] Based on the above exemplary scenario description, the electronic cigarette power control method provided by the embodiment of the present application is introduced below.

[0047] See also Figure 3 , Figure 3 This is a flow chart of an electronic cigarette power control method provided in one embodiment of the present application. The method includes the following steps:

[0048] S31. Receive a charging pulse sequence.

[0049] In this step, the charging pulse sequence is the current connected to the charging interface of the electronic cigarette. The charging pulse sequence carries power control information, which is used to transmit the power control information to the control component of the electronic cigarette to adjust the working power of the electronic cigarette. Specifically, the charging pulse sequence in the embodiment of the present application transmits power control information through the on and off states of the current. For example, the charging pulse sequence is a current that is on for 20ms, off for 10ms, then on for 40ms, and then off for 10ms. The power control information can be transmitted through some parameters of the charging pulse sequence (such as the on time and the off time). Unlike the conventional continuously on charging pulse sequence, the power replenishment capacity of the electronic cigarette battery is quite limited due to frequent shutdowns. By receiving the charging pulse sequence to obtain power control information, compared with the existing technology, there is no need to add additional hardware equipment, and the power control information can be received using the existing charging interface.

[0050] In this step, the charging pulse sequence can be understood as an electrical signal consisting of alternating current signals: an on-signal and an off-signal. By reading some characteristic parameters of the on-signal and the off-signal and comparing them with pre-set parameters, the electronic cigarette can retrieve the corresponding information and perform the corresponding power adjustment operation. For example, if the duration of one on-signal in the charging pulse sequence is 3ms, it means that the operating power represented by the charging pulse sequence is 3V. The electronic cigarette adjusts the operating power of the electronic cigarette to 3V based on the 3ms on-signal duration. It is understood that in other embodiments, the power control information can be represented in other forms, such as the voltage of the charging pulse sequence. When the charging voltage is 3V, it represents one type of information, when the charging voltage is 2.5V, it represents another type of information, and when the charging voltage is 2V, it represents another type of information. This allows the charging pulse sequence to convey richer information and reduces the data required to transmit power control information.

[0051] S32: Sampling according to the charging pulse sequence to obtain a signal sampling sequence.

[0052] In this step, since the charging pulse sequence only includes an on-signal and an off-signal, the charging pulse sequence is sampled to obtain a signal sampling sequence. Specifically, the charging pulse sequence may contain noise and may not be in a standard format, so it is necessary to sample it to obtain an accurate signal sampling sequence. In some embodiments, while sampling to obtain the signal sampling sequence, some data processing steps are also included, such as filtering the charging pulse sequence. Specifically in this embodiment, this step can be completed by the charging management chip, or a separate charging detection module can be set in the main control chip to directly read the charging status of the charging pulse sequence and convert it into a pulse signal.

[0053] In this step, the method of obtaining the signal sampling sequence based on the charging pulse sequence sampling can be specifically performed as follows, that is, the on-state signal is converted into the high-level voltage of the pulse signal, and the off-state signal is converted into the low-level voltage of the pulse signal. Since the on-state and the off-state signal of the charging pulse sequence must appear alternately, a high-level voltage time and a low-level voltage time can be combined into a pulse signal. The on-time of the pulse signal is the high-level voltage time, and the off-time is the low-level voltage time. For details in the embodiment, please refer to Figure 4 , Figure 4 A schematic diagram illustrating a pulse signal provided for an embodiment of the present application. The high-level voltage time and the low-level voltage time of the pulse signal represent different digital passwords, respectively. For example, a high-level voltage time of 50ms represents the number 5, and a low-level voltage time of 30ms represents the number 3. During the sampling process, a certain error is allowed in the charging pulse sequence. For example, a high-level voltage time of 54ms is 50ms after sampling, which still represents the number 5, while a high-level voltage time of 56ms is 60ms after sampling, which represents the number 6. It can be understood that in some embodiments, the high-level voltage time can also represent an alphabetic password. For example, a high-level voltage time of 10ms represents the English letter a, or represents the Roman letter I. There is no limitation on this, as long as the high-level voltage time and the low-level voltage time can represent characters with different meanings.

[0054] S33. Determine power control information according to the signal sampling sequence.

[0055] In this step, the numbers represented by the high-level voltage duration and low-level voltage duration of the pulse signal must match the pre-set numbers for the electronic cigarette. If a match is successful, the corresponding power control signal is generated. For example, if the charging pulse sequence is 50ms on, 20ms off, 60ms on, and 30ms off, then the corresponding signal sampling sequence is 50ms high-level voltage duration, 20ms low-level voltage duration, 60ms high-level voltage duration, and 30ms low-level voltage duration, representing the numbers 5-2-6-3. If the digital password built into the electronic cigarette is also 5-2-6-3, then this charging pulse sequence carries power control information. It will be understood that in other embodiments, the signal sampling sequence is represented only by the pulse signal of the on state, while the pulse signal of the off state is only used to distinguish different on states. For example, the charging pulse sequence is 50ms on, 20ms off, 60ms on, 20ms off, 30ms on, 20ms off, 40ms on, and 20ms off. The numbers obtained are 5-6-3-4, which are only related to the on-state time. It can be understood that if the numbers obtained based on the pulse signal do not match the built-in digital password, the power adjustment process will be automatically terminated. The electronic cigarette generates power control information for the electronic cigarette based on the digital password. The specific conversion method is shown below and will not be explained here.

[0056] In this step, the power control information is used to determine the operating power of the atomizer core. After the main control chip generates the power control information, it adjusts the operating power of the atomizer core according to the power control information. For example, if the power control information includes a target operating power, the main control chip directly adjusts the operating power of the atomizer core to the target operating power.

[0057] S34. Adjust the operating power of the atomizer core according to the power control information.

[0058] In this step, the electronic cigarette's power control signal is generated by the main control chip and output to the atomizer core to adjust the electronic cigarette's operating power. Specifically, the greater the atomizer core's operating power, the stronger the heating effect. Corresponding to different types of e-liquid, the larger the amount of smoke produced, and vice versa. Customers can use the power control signal to change the atomizer core's operating power based on the type of e-liquid and their preferred smoke volume, thereby adjusting the amount of smoke produced by the electronic cigarette. Compared to re-burning the chip, this saves the time and material costs of removing and replacing the chip. Compared to using other methods such as receiving electromagnetic signals or mechanical switches to adjust the operating power, using the charging port for adjustment reduces manufacturing costs.

[0059] In summary, the electronic cigarette power control method provided in this application transmits power control information to the electronic cigarette by using a charging pulse sequence that carries power control information. After the electronic cigarette converts the charging pulse sequence into a signal sampling sequence in the form of a pulse signal, the main control chip generates a power control signal according to the pulse signal sampling sequence, and adjusts the working power of the atomization core according to the power control signal, thereby achieving the effect of adjusting the amount of smoke of the electronic cigarette.

[0060] The electronic cigarette power control circuit provided by the embodiments of the present application is described in detail below.

[0061] See also Figure 5 , Figure 5 This is a schematic diagram of the architecture of an electronic cigarette charging circuit provided in one embodiment of the present application. The electronic cigarette power control circuit includes a charging interface 51, a charging management chip 52, a main control chip 53, and an atomizer core (not shown). The charging interface is used to receive a charging pulse sequence sent by a transmitting device, the charging management chip is used to monitor the charging pulse sequence input by the charging interface, and the main control chip is used to generate and output a power control signal based on the power control information carried by the charging pulse sequence. After receiving the power control signal, the atomizer core adjusts its operating power according to the power control signal.

[0062] The charging interface includes multiple input lines 511 for grounding, receiving input current, receiving data, receiving clock signals, and receiving control signals. Among them, the line 511 for receiving input current is a power output pin for connecting to the charging management chip 52.

[0063] The charging management chip 52 is electrically connected to the charging interface 51 . A power input pin 521 is provided outside the charging management chip 52 for connecting to the power output pin 511 , so that the charging management chip 52 can obtain the input current status of the charging interface 51 .

[0064] The current sampling circuit 54 includes a sampling resistor 542 and a current sampling pin 541 . One end of the sampling resistor 542 is connected to a node between the power output pin 511 and the power input pin 521 .

[0065] The main control chip 53 is connected to the current sampling pin 541 and the atomizer core output port. The main control chip 53 determines and generates power control information according to the current signal transmitted by the current sampling pin 541, and then controls the working power of the atomizer core according to the power control information.

[0066] See also Figure 6 , Figure 6This is a schematic diagram of the architecture of an electronic cigarette main control chip provided in one embodiment of the present application. The main control chip 53 is connected to the current sampling circuit 541 to obtain the on and off states of the charging pulse sequence and sample them as a signal sampling sequence. The signal sampling sequence includes multiple pulse signals arranged in sequence, and the period of each pulse signal corresponds to a digital code. For example, for the signal sampling sequence 50ms-60ms-30ms-40ms, dividing the high-level voltage duration by 10ms will yield the corresponding pulse signal number. For example, a high-level voltage duration of 50ms corresponds to digital code 5, a high-level voltage duration of 60ms corresponds to digital code 6, and so on, resulting in digital codes 5-6-3-4. This digital code can form the power control information. The pulse signal includes multiple digital codes, and adjacent digital codes are distinguished by low-level voltages. For example, if the low-level voltage duration is uniformly set to 20ms, then when the main control chip 53 detects a falling edge of a pulse, it will detect a rising edge of the pulse again every 20ms. At this time, the high-level voltage duration is read to determine the next digital code, thereby distinguishing multiple different digital codes. It should be noted that adjacent digital passwords should be set to different numbers as much as possible to improve the distinction of the digital passwords.

[0067] Furthermore, the periods of two adjacent pulse signals can be set to different times. For example, the high-level voltage period corresponding to the first digit of the digital password is 50ms, and the high-level voltage period corresponding to the second digit of the digital password is 60ms. This can improve the distinction between adjacent passwords and avoid interference from other signals. It is understood that the more pulse signal groups there are and the longer the number of digits in the digital password, the less likely other signals will interfere with the actual power control information. It is understood that in some other embodiments, the digital password can also be determined based on the low-level voltage period of the pulse signal. For example, if the low-level voltage period is 30ms, the corresponding digital password is determined to be 3. In other embodiments, the digital password can also be determined based on both the high-level voltage period and the low-level voltage period of the pulse signal. For example, for a signal sampling sequence of: high-level voltage 50ms - low-level voltage 20ms - high-level voltage 60ms - low-level voltage 10ms - high-level voltage 30ms - low-level voltage 40ms, the corresponding digital password is 5-2-6-1-3-4. The above methods can be selected and implemented by those skilled in the art according to actual circumstances and are not limited to this.

[0068] The digital code for the pulse signal consists of a guide code and an adjustment code. The guide code confirms that the pulse signal carries power control information, while the adjustment code represents the target power control value to be adjusted. Specifically, the guide code is located in the front portion of the pulse signal, while the adjustment code is located in the back portion. Only after the main control chip confirms the guide code is correct will it generate a power control signal based on the adjustment code and send it to the atomizer coil. For example, if the digital code is 5-6-3-4, where the first three digits 5-6-3 are the guide code, if the main control chip also has the same pre-stored digital code 5-6-3, the two match, and the fourth digit 4 is identified as the adjustment code. If the first three digits do not match, the fourth digit is not identified as the adjustment code, and the power adjustment process is terminated. The adjustment code typically does not directly represent the target power to be adjusted, but rather the power level of the atomizer coil. For example, 4 represents the fourth power level, corresponding to an operating power of 3.4V. Based on the adjustment code 4, the main control chip will issue a 3.4V operating power command to the atomizer coil.

[0069] The atomizer core is used to heat the e-liquid so that it boils and produces smoke. In some embodiments, the heating structure of the atomizer core is a resistance wire. The heating effect of the resistance wire varies depending on the operating power, and the amount of smoke produced by the e-liquid also varies accordingly. If the user needs to adjust the amount of smoke, a charging pulse sequence carrying the corresponding power control information can be sent to the electronic cigarette. Specifically, the atomizer core is pre-set with 6 gears of operating power, namely 3.1V, 3.2V, 3.3V, 3.4V, 3.5V and 3.6V. When the main control chip receives the digital password 5-6-3-4, it generates a power control signal for the fourth gear operating power of 3.4V. When the main control chip receives the digital password 5-6-3-1, it generates a power control signal for the first gear operating power of 3.1V. In this way, the user can increase or decrease the operating power of the atomizer core to adjust the amount of smoke produced by the electronic cigarette to an appropriate level.

[0070] In summary, the electronic cigarette power control circuit provided by the present application receives a charging pulse sequence through a charging interface, and then samples the charging pulse sequence to obtain a sampling signal sequence. The sampling signal sequence is then parsed by the main control signal, and the digital password therein is verified to generate power control information. The main control chip controls the atomizer core to adjust the working power according to the power control information, thereby adjusting the amount of smoke emitted by the electronic cigarette. Using this method for power control can effectively alleviate the problem that the original electronic cigarette cannot adjust the working power due to the one-time burning chip, and effectively utilizes the original charging interface of the electronic cigarette, reducing the additional cost incurred by adding the power control function.

[0071] An embodiment of the present application also provides a transmitting device, which is used to transmit a charging pulse sequence and has a transmitting interface. The transmitting interface is used to connect to the charging interface of an electronic cigarette, so that the power control circuit of the electronic cigarette determines power control information according to the transmitted charging pulse sequence, thereby adjusting the working power of the atomizer core.

[0072] Specifically, see Figure 7 , Figure 7 Schematic diagram of the circuit architecture of a transmitter device provided in one embodiment of the present application. The transmitter device includes a power input port 72 for configuring an input current signal, a pulse output port 73 for electrically connecting to a power control circuit, a pulse rectifier circuit 74 electrically connected to the power input port 72 and the pulse output port 73, respectively, and a control chip 71 electrically connected to the pulse rectifier circuit 74. The control chip 71 is electrically connected to the pulse rectifier circuit 74 to control the pulse rectifier circuit 74 to shape the current signal into a charging pulse sequence, and to send the charging pulse sequence to the power control circuit through the pulse output port 73, so that the power control circuit determines power control information based on the charging pulse sequence and adjusts the operating power of the atomizer core based on the power control information.

[0073] In one embodiment, the pulse rectifier circuit 74 includes an N-type transistor 741 and a P-type transistor 742, the base of the N-type transistor 741 is connected to the control chip 71, the emitter of the N-type transistor 741 is grounded, the collector of the N-type transistor 741 is connected to the base of the P-type transistor 742, the emitter of the P-type transistor 742 is connected to the power input port 72, and the collector of the P-type transistor 742 is connected to the pulse output port 73. The pulse rectifier circuit 74 shapes the direct current transmitted from the power input port 72 into a pulse current according to the control signal transmitted by the control chip 71.

[0074] The present application also provides an electronic cigarette, including a charging module, a computing module, a matching module, and an execution module. Specifically, the electronic cigarette includes:

[0075] A charging module, used for obtaining a charging pulse sequence;

[0076] A monitoring module is used to respond to a charging pulse sequence inputted by the charging interface and output a pulse signal according to the power control information carried by the charging pulse sequence;

[0077] A control module, configured to respond to the pulse signal output by the monitoring module and generate a power control signal according to the pulse signal;

[0078] The power module is used to adjust the working power of the electronic cigarette in response to the power control signal.
