[0046] The embodiment of the present application provides an electronic atomization device and a charging method thereof. By setting an interface shared by fast charging and conventional charging on the electronic atomization device, there is no need to embed a fast charging protocol in the first control chip, and there is no need to set a fast charging circuit. It is then possible to switch between direct fast charging and conventional charging. The circuit structure is simple, charging is fast, miniaturized production can be achieved, the manufacturing cost is low, a variety of charging methods are available, and the use is flexible and diverse.

[0047] The charging technology commonly used in the electronic atomization devices currently in circulation on the market is the conventional charging method, which uses a low voltage and low power charging method, which is the so-called slow charging. This charging method is to install a conventional charging control chip in the electronic atomization device, and set a current limiting and voltage limiting circuit on the chip. The function of the current limiting and voltage limiting circuit during charging is that no matter how large the voltage and power of the external power supply are, the rechargeable battery in the electronic atomization device can only be charged within the current limiting and voltage limiting voltage range.

[0048] In recent years, a fast charging technology has emerged in electronic atomization devices, which uses a high-voltage and high-power charging method. This charging method requires the use of a globally common fast charging protocol, and requires the setting of a charging protection circuit to quickly charge the rechargeable battery. Currently, the electronic atomization device products on the market need to embed the fast charging protocol in the control chip of the electronic atomization device, and at the same time set up a charging protection circuit for fast charging in the electronic atomization device, so as to achieve fast charging of the rechargeable battery in the electronic atomization device.

[0049] The electronic atomization device provided in the embodiment of the present application removes the fast charging protocol and the fast charging protection circuit in the electronic atomization device, and only retains an integrated charging interface that can perform fast charging and conventional charging, thereby achieving miniaturization and low cost of the electronic atomization device.

[0050] Please refer to the following Figure 1The electronic atomization device 100 shown in the embodiment of the present application includes a charging interface 101, a voltage detection device 102, a first control chip 103, a fast charging switch device 104, a conventional charging switch device 105, a conventional charging circuit 106 and a rechargeable battery 107, wherein:

[0051] Four terminals of the charging interface 101 are respectively connected to the voltage detection circuit 102, the first control chip 103, the conventional charging switch device 105, and the first terminal of the fast charging switch device 105, that is, the first terminal to the fourth terminal of the charging interface 101 are respectively electrically connected to the first terminal of the voltage detection circuit 102, the first terminal of the first control chip 103, the first terminal of the conventional charging switch device 105, and the first terminal of the fast charging switch device 105. In addition, the fifth terminal of the charging interface 101 is grounded.

[0052] The other end of the voltage detection circuit 102 is connected to one end of the first control chip 103 .

[0053] The other two ends of the first control chip 103 are respectively connected to the second end of the conventional charging switch device 105 and the second end of the fast charging switch device 104, that is, the second end and the third end of the first control chip 103 are respectively electrically connected to the second end of the conventional charging switch device 105 and the second end of the fast charging switch device 104.

[0054] A third terminal of the conventional charging switch device 105 is connected to a first terminal of the conventional charging circuit 106 .

[0055] A second terminal of the conventional charging circuit 106 is connected to a first terminal of the rechargeable battery 107 .

[0056] The third terminal of the fast charging switch device 104 is connected to the second terminal of the rechargeable battery 107 .

[0057] A third terminal of the rechargeable battery 107 is grounded.

[0058] In the embodiment of the present application, the first control chip 103 of the electronic atomization device 100 does not have a fast charging protocol embedded in it, nor is a charging protection circuit for protecting the rechargeable battery installed in the electronic atomization device 100. When the electronic atomization device 100 is electrically connected to an external charging device for fast charging, the external charging device needs to have a fast charging protocol embedded in it, and a charging protection circuit is provided inside the charging device.

[0059] In this way, when the electronic atomization device needs to be quickly charged, there is no need to embed a fast charging protocol for quickly charging the rechargeable battery 107 in the first control chip 103, nor is there a need to install a charging protection circuit in the electronic atomization device 100 to protect the rechargeable battery. Instead, the charging interface 101 only needs to be electrically connected to the charging interface of an external charging device with a fast charging technology, and the rechargeable battery 107 can be directly quickly charged. Therefore, the circuit structure of the fast charging part in the electronic atomization device 100 is simplified, the charging is fast, and the production can be miniaturized in advance, and the production cost is low. When the electronic atomization device 100 needs to be conventionally charged, the charging interface 101 is electrically connected to the charging interface of an external charging device with a conventional charging technology, and then the rechargeable battery 107 is conventionally charged. In this way, the same electronic atomization device 100 can realize multiple charging methods of fast charging and conventional charging through only one charging interface, and the user can have more choices of charging methods. The charging methods are flexible and diverse, which brings greater convenience to the user, not only saving the utilization of resources, but also making the product more environmentally friendly.

[0060] Specifically, to help readers fully understand the technical solution of this application, please refer to Figure 2 , Figure 2 The charging device 200 includes a second control chip 201, a charging structure 202, a charging protection structure 203, a fast charging interface 204 and a conventional charging interface 205. The second control chip 201 is electrically connected to one end of the charging structure 202, the fast charging interface 204 and the conventional charging interface 205 respectively, one end of the charging protection structure 203 is electrically connected to the other end of the charging structure 202, and the other end of the charging protection structure 203 is electrically connected to the fast charging interface 204 and the conventional charging interface 205 respectively.

[0061] In the charging device 200, the charging protection structure 203 is a charging protection circuit, which is used to protect the rechargeable battery 107 in the electronic atomization device 100 when the electronic atomization device 100 is fast charged or normally charged, so as to prevent the rechargeable battery 107 from being damaged. In other words, the charging protection structure 203 in the charging device 200 is provided with both a fast charging protection circuit and a normal charging protection circuit.

[0062] Depend on Figure 2It can be seen that the charging protection structure 203, i.e., the charging protection circuit, which is usually set in the electronic atomization device 100, is removed and set in the charging device 200. In addition, the fast charging protocol is also embedded in the second control chip 201 of the charging device 200. In this way, when fast charging is performed, the fast charging protocol matches the charging protection structure 203, and the electronic atomization device 100 is fast charged through the fast charging interface 204 of the charging device 200. After the charging interface 101 of the electronic atomization device 100 is electrically connected to the fast charging interface 204 in the charging device 200, the working principle of the electronic atomization device 100 is as follows.

[0063] First, the charging interface 101 is used to access the charging voltage of the external charging device 200 , and transmit the charging voltage from the charging device 200 to the voltage detection circuit 102 and the first control chip 103 respectively.

[0064] Next, the voltage detection circuit 102 is used to detect the voltage value of the charging voltage from the external charging device 200 and send the voltage value to the first control chip 103 .

[0065] Since the charging interface 101 of the electronic atomization device 100 is connected to the fast charging interface 204 of the charging device 200 at this time, the voltage detection circuit 102 will detect the large charging voltage and large charging current required for fast charging, and then send the detection result to the first control chip 103.

[0066] The first control chip 103 is used to determine whether the voltage value is greater than or equal to a preset voltage threshold value preset in the electronic atomization device 100. When the first control chip 103 determines that the voltage value is greater than or equal to the preset voltage threshold value, the fast charging switch device 104 is turned on, while the conventional charging switch device 105 remains disconnected. It should be noted that the preset voltage threshold value is usually preset in a memory (not shown) of the electronic atomization device.

[0067] When the fast charging switch device 104 is in the on state, the charging interface 101 is used to directly and quickly transmit the fast charging voltage to the rechargeable battery 107 .

[0068] As can be seen from the above, the electronic atomization device 100 of the embodiment of the present application has a simple circuit structure, and since the fast charging protocol and the fast charging protection circuit are removed therein, charging is also faster.

[0069] from Figure 2It can also be seen that the fifth end of the charging interface 101 is grounded, and the third end of the rechargeable battery 107 is also grounded. Therefore, when the charging interface of the electronic atomization device 100 is electrically connected to the fast charging interface 204 of the charging device 200, the charging device 200, the charging interface 101 of the electronic atomization device 100, the fast charging switch device 104 and the rechargeable battery 107 form an electrical circuit, and the rechargeable battery 107 is charged through the control of the first control chip 103.

[0070] On the side of the charging device 200, since the second control chip 201 of the charging device 200 is embedded with a fast charging handshake protocol, and the fast charging handshake protocol is compatible with the fast charging interface 204, the large charging voltage of the fast charging will be transmitted from the fast charging interface of the charging device 200 to the charging interface 101 of the electronic atomization device through the fast charging interface 204, thereby realizing fast charging of the rechargeable battery 107 in the electronic atomization device 100.

[0071] In the embodiment of the present application, the fast charging voltage value can be 9 volts, 12 volts or 22 volts, which is not limited here.

[0072] When the electronic atomization device 100 needs to be charged conventionally, the charging interface 101 can be electrically connected to the conventional charging interface 205 of the charging device 200, so that the conventional charging interface 205 of the charging device 200, the charging interface of the electronic atomization device 100, the conventional charging switch device 105, the conventional charging circuit 105 and the rechargeable battery 107 form an electrical circuit.

[0073] The working principle of conventional charging is as follows:

[0074] First, the voltage detection circuit 102 detects the normal charging voltage transmitted from the charging device 200, and then sends the detected voltage value to the first control chip 103. Next, the first control chip 103 also determines whether the voltage value is greater than or equal to the preset voltage threshold based on the voltage value sent by the voltage detection circuit 102.

[0075] When the first control chip 103 determines that the voltage value is less than the preset voltage threshold, the first control chip 103 is further configured to turn on the normal charging switch device 105 and keep the fast charging switch device 104 turned off.

[0076] Next, the conventional charging circuit is used to transmit the charging voltage transmitted from the charging interface 101 to the rechargeable battery 107 when the conventional charging switch device 105 is in the on state.

[0077] It should be noted that the conventional charging circuit 105 limits current and voltage, and only allows a voltage of no more than 5 volts to pass through to charge the rechargeable battery 107 .

[0078] On the side of the charging device 200, when the second control chip 201 receives the information that the electronic atomization device 100 is electrically connected to the conventional charging interface 205 of the charging device 200, the second control chip 201 will control its own internal charging structure 202 and charging protection structure 203, and transmit conventional voltage to the electronic atomization device 100 through the conventional charging interface 205, thereby realizing conventional charging of the rechargeable battery 107 of the electronic atomization device 100.

[0079] It should be noted that the threshold range of the preset voltage threshold is greater than 5 volts and less than 9 volts. Preferably, the preset voltage threshold is 7.5 volts.

[0080] In the embodiment of the present application, the charging interface 101 may be a TYPE-A interface, a TYPE-B interface, a TYPE-C interface, or a dual-contact interface, which is not specifically limited here.

[0081] In the embodiment of the present application, the electronic atomization device 100 may be an electronic cigarette, an earphone, an electronic bracelet or a mobile phone, which is not specifically limited here.

[0082] In the embodiment of the present application, not only the fast charging protocol and the charging protection circuit are removed from the electronic atomization device 100, but also the fast charging interface and the conventional charging interface are integrated into one interface, thereby further simplifying the structure of the electronic atomization device and achieving miniaturization and low price of the product.

[0083] In order to further understand the technical solution of the present application, an application scenario of a specific embodiment is described below.

[0084] See also Figure 3 , Figure 3 In the illustrated embodiment, the charging device is a charging cable with a fast charging function, including a first main control chip, a charging module, a charging protection circuit, a second charging interface, a fast charging interface J1, a control switch K1, and an input interface. Among them, the second charging interface is an interface for conventional charging, J1 is an interface for fast charging, K1 is a control switch used by the first main control chip to control fast charging or conventional charging, and the input interface is used to connect to an external power source.

[0085] It should be noted that the conventional charging in this embodiment is the so-called slow charging.

[0086] In this embodiment, the electronic atomization device is an electronic cigarette, including a second main control chip, a charging interface, a voltage detection circuit, a control switch K2, an inverter U1, a control switch K3, a conventional charging circuit, and a rechargeable battery BAT. Among them, the control switch K2 is used to disconnect the circuit for fast charging, the control switch K3 is used to switch the circuit for conventional charging, and the inverter U1 is used to switch on the control switch K2 or the control switch K3 according to the voltage value detected by the voltage detection circuit through the control of the second main control chip. When the voltage value is a large voltage for fast charging, the second main control chip controls the inverter U1 to be electrically connected to the control switch K2, and controls the inverter U1 to disconnect the electrical connection with the control switch K3. When the voltage value is a small voltage for conventional charging, the second main control chip controls the electrical connection between the inverter U1 and the control switch K3, and controls the inverter to be electrically connected to the control switch K2.

[0087] When the electronic cigarette needs to be quickly charged, the charging interface of the electronic cigarette is electrically connected to the fast charging interface J1 of the charging line with integrated fast charging function for fast charging. When the electronic cigarette only needs conventional charging, the charging interface of the electronic cigarette is electrically connected to the second charging interface of the charging line for conventional charging.

[0088] The electronic atomization device in the embodiment of the present application is described in detail above. The charging method of the electronic atomization device in the embodiment of the present application is specifically described below.

[0089] Reference Figures 2 to 4 The present application embodiment provides a charging method for an electronic atomization device, the electronic atomization device is the electronic atomization device in all the above embodiments, and the charging method may include the following steps:

[0090] 401. The charging interface is connected to a charging voltage of an external charging device, and the charging voltage from the charging device is transmitted to the voltage detection circuit and the first control chip respectively;

[0091] In an embodiment of the present application, when the electronic atomization device 100 needs to be charged, the charging interface 101 of the electronic atomization device 100 is electrically connected to the fast charging interface 204 or the conventional charging interface 205 of the external charging device 200, and then the charging interface 101 can receive the charging information sent by the charging device 200 through one of the charging interfaces.

[0092] 402. The voltage detection circuit detects a voltage value of a charging voltage from a charging device, and sends the voltage value to a first control chip;

[0093] After receiving the charging voltage transmitted from the charging interface 101 , the voltage detection circuit 102 detects the voltage value of the charging voltage and then sends the measured voltage value to the first control chip 103 .

[0094] 403. The first control chip determines whether the voltage value is greater than or equal to a preset voltage threshold;

[0095] Then, the first control chip 103 determines whether the voltage value is greater than or equal to a preset voltage threshold value according to the voltage value detected by the voltage detection circuit 102 . The preset voltage threshold value is preset in a memory (not shown) of the electronic atomization device 100 .

[0096] If yes, execute step 404.

[0097] 404. The first control chip turns on the fast charging switch device and keeps the conventional charging device disconnected;

[0098] When the first control chip 103 determines that the voltage value is greater than or equal to the preset voltage threshold, it indicates that a high charging voltage for fast charging is connected, so the first control chip 103 turns on the fast charging switch device 104 and keeps the conventional charging device 105 disconnected.

[0099] 405. The charging interface directly transmits the charging voltage to the rechargeable battery.

[0100] When the fast charging switch device 104 is in the on state, the charging interface 101 can directly transmit the fast charging voltage to the rechargeable battery.

[0101] by Figure 3 Taking the specific example of the electronic cigarette, when the first main control chip controls the charging switch K1 to be turned on, the input interface on the charging line can directly transmit the electrically connected external power supply to the fast charging interface J1 on the charging line, and the high charging voltage for fast charging is transmitted to the charging interface of the electronic cigarette. When the second main control chip controls the fast charging switch K2 to be turned on, the fast charging voltage will be directly transmitted to the rechargeable battery, thereby charging the rechargeable battery.

[0102] In the present application, refer again to Figure 4When the electronic atomization device 100 needs to be quickly charged, the charging interface 101 of the electronic atomization device 100 is electrically connected to the fast charging interface 204 of the charging device 200, so as to access the charging voltage of the external charging device 200. According to the voltage value detected by the voltage detection circuit 102, the first control chip 103 determines whether the voltage value is greater than or equal to the preset voltage threshold. Once it is determined that the voltage value is greater than or equal to the preset voltage threshold, the first control chip 103 turns on the fast charging switch device 104, so that the large charging voltage of the fast charging is directly transmitted from the charging interface 101 to the rechargeable battery 107 through the fast charging switch device 104. Since the electronic atomization device 100 does not have a fast charging charging protection circuit, nor is it embedded with a fast charging protocol, but is directly fast charged by electrically connecting the charging protection circuit provided with a fast charging and the charging device 200 embedded with a fast charging protocol, the circuit structure in the electronic atomization device 100 is simplified, the charging is fast, and miniaturization production can be achieved, and the manufacturing cost is low.

[0103] Reference Figure 5 In another embodiment of the charging method of the electronic atomization device of the present application, the following steps may be included:

[0104] 501. The charging interface is connected to a charging voltage of an external charging device, and the charging voltage from the charging device is transmitted to the voltage detection circuit and the first control chip respectively;

[0105] 502. The voltage detection circuit detects a voltage value of a charging voltage from a charging device, and sends the voltage value to a first control chip;

[0106] 503. The first control chip determines whether the voltage value is greater than or equal to a preset voltage threshold;

[0107] After the first control chip 103 receives the voltage value of the charging voltage of the charging device 200 detected by the voltage detection circuit 102, the first control chip 103 determines whether the voltage value of the charging voltage is greater than or equal to the preset voltage threshold. If so, execute step 504; if not, execute step 505.

[0108] 504. The first control chip turns on the fast charging switch device and keeps the conventional charging switch device turned off;

[0109] In this embodiment, steps 501 to 504 are the same as those described above. Figure 4 Steps 401 to 404 in the illustrated embodiment are similar and will not be described in detail herein.

[0110] 505. The first control chip turns on the conventional charging switch device and keeps the fast charging switch device turned off;

[0111] When the first control chip 103 determines that the voltage value of the charging voltage detected by the voltage detection circuit 102 is less than a preset voltage threshold preset in the memory (not shown) of the electronic atomization device 100 , the conventional charging switch device 105 is turned on while the fast charging switch device 104 remains disconnected.

[0112] 506. The charging interface transmits the charging voltage to the rechargeable battery through a conventional charging switch device.

[0113] In this embodiment, after the first control chip 103 turns on the conventional charging switch device 105 , the charging interface 101 can transmit a low-voltage charging voltage to the conventional charging switch device 105 , and then transmit it to the rechargeable battery 107 , thereby realizing conventional charging of the rechargeable battery 107 .

[0114] It should be noted that the threshold range of the preset voltage threshold may be greater than 5 volts and less than 9 volts. Preferably, the preset voltage threshold is 7.5 volts.

[0115] In this embodiment, the fast charging interface and the conventional charging interface are integrated into one charging interface. When charging, the user only needs to select the fast charging interface 204 or the conventional charging interface 205 connected to the external charging device 200 according to the needs of the user to achieve fast charging or conventional charging. This not only simplifies the design of the charging interface, but also because the fast charging protocol and circuit structure are not set in the electronic atomization device 100, it greatly simplifies the internal structural design of the electronic atomization device, reduces production costs, and can also reduce pollution to the environment when it is discarded.

[0116] An embodiment of the present application also provides a computer storage medium, which is used to store computer software instructions used for the aforementioned electronic atomization device, including instructions for executing a program designed for the electronic atomization device.

[0117] The embodiment of the present application also provides a computer program product, which includes computer software instructions, which can be loaded by a first control chip to implement the aforementioned Figure 4 and Figure 5 The method flow of the embodiment shown.
