[0034] The embodiment of the present application provides an electronic atomization device and a charging method thereof. By arranging a first fast charging interface and a first conventional charging interface on the electronic atomization device, it can be directly electrically connected to an external charging device for fast charging or conventional charging. The circuit structure is simple, the 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.

[0035] 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.

[0036] Recently, a fast charging technology has emerged for electronic atomization devices, which uses a high-voltage and high-power charging method. This charging method requires the use of a universal 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.

[0037] 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 the fast charging interface, thereby achieving miniaturization and low cost of the electronic atomization device.

[0038] Please refer to the following Figure 1 The electronic atomization device 200 shown in the embodiment of the present application includes a first fast charging interface 201, a first conventional charging interface 202, a rechargeable battery 203 and a conventional charging control chip 204. The rechargeable battery 203 is electrically connected to one end of the conventional charging control chip 204 and the first fast charging interface 201, respectively, and the first conventional charging interface 201 is electrically connected to the other end of the conventional charging control chip 204. As mentioned above, the conventional charging control chip 204 is used to control the rechargeable battery 203 to perform conventional charging.

[0039] related Figure 1 The charging device 100 shown will be described later.

[0040] In the embodiment of the present application, when the electronic atomization device 200 needs to be quickly charged, there is no need to embed a fast charging protocol for quickly charging the rechargeable battery 203 in the control chip of the electronic atomization device 200, nor is there a need to install a charging protection circuit in the electronic atomization device 200 to protect the rechargeable battery 203 and charge the rechargeable battery 203 by limiting voltage and current. Instead, it is only necessary to electrically connect the first fast charging interface 201 to an external charging device 100 equipped with fast charging technology to directly charge the rechargeable battery 203 quickly. This simplifies the circuit structure in the electronic atomization device 200, makes charging fast, and enables miniaturized production with low manufacturing costs. When the electronic atomization device 200 needs to be charged conventionally, the first conventional charging interface 202 is electrically connected to an external charging device 100 equipped with conventional charging technology, and then the rechargeable battery 203 is charged conventionally. In this way, the same electronic atomization device 200 can realize multiple charging methods of fast charging and conventional charging. The user can have more choices of charging methods, and the charging methods are flexible and diverse, which brings greater convenience to the user. It not only saves the utilization of resources, but also makes the product more environmentally friendly.

[0041] like Figure 1 As shown, the charging device 100 includes a first control chip 101, a first charging structure 102, a charging protection structure 103, a second fast charging interface 104 and a second conventional charging interface 105. The first control chip 101 is electrically connected to one end of the first charging structure 102, the second fast charging interface 104 and the second conventional charging interface 105 respectively, one end of the charging protection structure 103 is electrically connected to the other end of the first charging structure 102, and the other end of the charging protection structure 103 is electrically connected to the second fast charging interface 104 and the second conventional charging interface 105 respectively.

[0042] In the charging device 100, the charging protection structure 103 is a charging protection circuit, which is used to protect the rechargeable battery 203 in the electronic atomization device 200 when the electronic atomization device 200 is fast charged or normally charged, so as to prevent the rechargeable battery 203 from being damaged. In other words, the charging protection structure 103 in the charging device 100 is provided with both a fast charging protection circuit and a normal charging protection circuit.

[0043] Depend on Figure 1It can be seen that the charging protection structure 103, that is, the charging protection circuit, which is usually set in the electronic atomization device 200, is removed and set in the charging device 100. In addition, the fast charging protocol is also embedded in the first control chip 101 of the charging device 100. In this way, when fast charging is performed, the fast charging protocol and the charging protection structure 103 are matched, and the electronic atomization device 200 is fast charged through the second fast charging interface 104 of the charging device 100. After the first fast charging interface 201 of the electronic atomization device 200 is electrically connected to the second fast charging interface 104 of the charging device 100, the large charging voltage and large charging current can be directly and quickly transmitted to the rechargeable battery 203. The circuit structure is simple, and because the fast charging protocol and the fast charging protection circuit are removed from it, the charging will be faster.

[0044] from Figure 1 It can be seen that during fast charging, the first fast charging interface 201 of the electronic atomization device 200 can be electrically connected to the second fast charging interface 104 of the charging device 100; during conventional charging, the first conventional charging interface of the electronic atomization device 200 can be electrically connected to the second conventional charging interface 105 of the charging device 100. At this time, the first control chip 101 of the charging device 100 controls the charging protection structure 103 to perform conventional charging protection on the rechargeable battery 203 of the electronic atomization device 200.

[0045] Specifically, by Figure 1 It can also be seen that in the electronic atomization device 200 of the embodiment of the present application, one end of the rechargeable battery 203 is electrically connected to one end of the first fast charging interface 201, the other end of the rechargeable battery 203 and the other end of the first fast charging interface 201 are both grounded, one end of the first conventional charging interface 202 is electrically connected to the other end of the conventional charging control chip 204, and the other end of the first conventional charging interface 202 is grounded.

[0046] When the first fast charging interface 201 of the electronic atomization device 200 is electrically connected to the second fast charging interface 104 of the charging device 100, the first fast charging interface 201, the rechargeable battery 203 and the charging device 100 form an electrical circuit, and the first control chip 101 in the charging device 100 will control the charging device 100 to charge the rechargeable battery 203 of the electronic atomization device 200 through the charging protection structure 103, the second fast charging interface, and the first fast charging interface 201 of the electronic atomization device 200.

[0047] When the first conventional charging interface 202 of the electronic atomization device 200 is electrically connected to the second conventional charging interface 105 of the charging device 100, the first conventional charging interface 202, the conventional charging control chip 204, the rechargeable battery 203 and the charging device 100 form an electrical circuit, and the conventional charging voltage control chip limits the current and voltage, allowing only a maximum voltage of 5 volts to pass through to charge the rechargeable battery 203. In this way, the first control chip 101 in the charging device 100 will control the charging device 100 to charge the rechargeable battery 203 of the electronic atomization device 200 through the charging protection structure 103, the second conventional charging interface 105, the first conventional charging interface 202 of the electronic atomization device and the conventional charging control chip 204.

[0048] Furthermore, in the embodiment of the present application, the types of the first fast charging interface 201 and the first regular charging interface 202 of the electronic atomization device 200 can be different, so that the user can ensure that the first regular charging interface 202 and the first fast charging interface 201 are not confused when charging, and prevent the wrong insertion into different types of interfaces of the external charging device 100. In other words, since the two interface types are obviously different from the naked eye, it will not happen that the first fast charging interface 201 of the electronic atomization device 200 is mistakenly inserted into the second regular charging interface of the charging device 100, nor will it happen that the first regular charging interface 202 of the electronic atomization device 200 is mistakenly inserted into the second fast charging interface 104 of the charging device 100, thereby avoiding the situation where normal charging cannot occur.

[0049] Furthermore, the interface type of one of the first fast charging interface 201 and the first conventional charging interface 202 of the electronic atomization device 200 can be a two-contact interface, and the interface type of the other can be a TYPE-A interface, a TYPE-B interface or a TYPE-C interface, which is not specifically limited here.

[0050] For example, the first fast charging interface 201 can be set as a two-contact interface, and the first regular charging interface 202 can be set as a TYPE-C interface. Alternatively, the first fast charging interface 201 can be set as a TYPE-C interface, and the first regular charging interface 202 can be set as a two-contact interface.

[0051] Of course, in this case, the external charging device 100 that can be used also needs to be set with at least two different charging interfaces to match the two different charging interfaces of the electronic atomization device 200. For example, when the first fast charging interface 201 of the electronic atomization device 200 is set as a two-contact interface, the second fast charging interface 104 of the charging device 100 also needs to be set as a two-contact interface so that the first fast charging interface 201 and the second fast charging interface 104 can be electrically connected. At the same time, the first conventional charging interface 202 of the electronic atomization device 200 and the second conventional charging interface 105 of the charging device 100 can be set as TYPE-C interfaces so that the first conventional charging interface 202 and the second conventional charging interface 105 can be electrically connected.

[0052] In the embodiment of the present application, the working principle of the conventional charging control chip 204 in the electronic atomization device 200 is that after the first conventional charging interface 202 is electrically connected to the second conventional charging interface 105 of the external charging device 100, it is first determined whether the voltage to be charged transmitted from the second conventional charging interface 105 to the first conventional charging interface 202 is less than the preset slow charging voltage threshold preset in the electronic atomization device 200. If so, after determining that the voltage to be charged is less than the preset slow charging voltage threshold, the first conventional charging interface 202 is controlled to transmit the voltage to be charged to the rechargeable battery 203 through the conventional charging control chip 204 itself, thereby performing conventional charging on the rechargeable battery 203. On the contrary, when the conventional charging control chip 204 determines that the voltage to be charged is greater than or equal to the preset slow charging voltage threshold, the voltage to be charged is prohibited from being transmitted to the rechargeable battery 203 through the conventional charging control chip 204 itself.

[0053] When the electronic atomization device 200 needs to be quickly charged, the first fast charging interface 202 of the electronic atomization device 200 is electrically connected to the second fast charging interface 105 of the external charging device 100, and then the fast charging voltage transmitted from the second fast charging interface 105 is directly transmitted to the rechargeable battery 203, thereby quickly charging the rechargeable battery 203.

[0054] Specifically, after the first fast charging interface 202 of the electronic atomization device 200 is electrically connected to the second fast charging interface 105 of the charging device 100, the first control chip 101 of the charging device 100 will immediately receive the electrical connection information transmitted from the second fast charging interface 104, so the first control chip 101 will send a fast charging instruction to the first charging structure 102, commanding the first charging structure 102 to transmit the fast charging voltage to the second fast charging interface 104 via the charging protection structure 103. The charging protection structure 103 may include a boost circuit required for fast charging, and may also include a buck circuit required for fast charging, and of course, may also include a boost circuit and a buck circuit required for fast charging at the same time. Then, the second fast charging interface 104 of the charging device 100 transmits the fast charging voltage to the first fast charging interface 201 of the electronic atomization device 200, and then the first fast charging interface 201 transmits the fast charging voltage to the rechargeable battery 203.

[0055] In the embodiment of the present application, the fast charging voltage value may be 9 volts, 12 volts or 22 volts, which is not specifically limited here. In addition, the slow charging voltage threshold is preset to be ≤5 volts.

[0056] In the embodiment of the present application, the electronic atomization device can be an electronic cigarette, an earphone, an electronic bracelet or a mobile phone, which is not specifically limited here.

[0057] 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.

[0058] Reference Figure 2 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:

[0059] 201. After the first fast charging interface is electrically connected to the second fast charging interface of the external charging device, receiving fast charging information sent by the charging device;

[0060] In an embodiment of the present application, when the electronic atomization device 200 needs to be quickly charged, the first fast charging interface 202 of the electronic atomization device 200 is electrically connected to the second fast charging interface 105 of the external charging device 100, and then the first fast charging interface 201 can receive the fast charging information sent by the charging device 100 through the second fast charging interface 105.

[0061] 202. The first fast charging interface transmits the fast charging voltage transmitted by the second fast charging interface to the rechargeable battery for direct fast charging.

[0062] At the same time or after the first fast charging interface 201 receives the fast charging information sent by the second fast charging interface 105 of the charging device 100, the first fast charging interface 201 will receive the fast charging voltage transmitted by the second fast charging interface 105, and then the first fast charging interface 201 can directly transmit the fast charging voltage to the rechargeable battery 203, thereby quickly charging the rechargeable battery 203.

[0063] 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.

[0064] It should be noted that Figure 2 In the charging method of the electronic atomization device 200 in the illustrated embodiment, step 201 and step 202 may be performed simultaneously, or step 202 may be performed after step 201 is performed, and the specific details are not limited here.

[0065] Reference Figure 3 In the embodiment of the present application, the charging method of the electronic atomization device 200 may perform the following steps:

[0066] 301. After the first fast charging interface is electrically connected to the second fast charging interface of the external charging device, receiving fast charging information sent by the charging device;

[0067] 302. The first fast charging interface transmits the fast charging voltage transmitted by the second fast charging interface to the rechargeable battery for direct fast charging;

[0068] In the embodiment of the present application, step 301 and step 302 are the same as the above Figure 2 Step 201 and step 202 in the illustrated embodiment are similar and are not specifically limited here.

[0069] 303. When the first conventional charging interface is electrically connected to the second conventional charging interface of the external charging device, the conventional charging control chip determines whether the charging voltage transmitted from the second conventional charging interface to the first conventional charging interface is less than a preset slow charging voltage threshold preset in the electronic atomization device;

[0070] In the embodiment of the present application, if there is sufficient charging time, slow charging can be used for charging. In this step, after the first conventional charging interface 202 of the electronic atomization device 200 is electrically connected to the second conventional charging interface of the charging device 100, the conventional charging control chip 204 can determine whether the charging voltage transmitted from the second conventional charging interface 105 of the external charging device 100 to the first conventional charging interface 202 of the electronic atomization device 200 is less than the preset slow charging voltage threshold preset in the electronic atomization device 200. If so, step 304 is executed; if not, step 305 is executed.

[0071] 304. The conventional charging control chip controls the first conventional charging interface to transmit the conventional charging voltage transmitted from the charging device to the rechargeable battery, thereby performing conventional charging on the rechargeable battery;

[0072] After the conventional charging control chip 204 determines that the voltage to be charged from the second conventional charging interface 105 of the charging device 100 is less than the preset slow charging voltage threshold preset in the electronic atomization device 200, the first control chip 101 in the charging device 100 can control the first charging structure 102 to output the conventional charging voltage as the voltage to be charged to the second conventional charging interface 105 through the charging protection structure 103. The second conventional charging interface 105 then transmits the conventional charging voltage to the conventional charging control chip 204, and then transmits it to the rechargeable battery 203 through the conventional charging control chip 204.

[0073] It should be noted that in the embodiment of the present application, steps 301 and 302 may be performed first, and then steps 303 and 304, or steps 303 and 304 may be performed first, and then steps 301 and 302, and the specific details are not limited here.

[0074] 305. The conventional charging control chip prohibits the voltage to be charged from being transmitted to the rechargeable battery through the conventional charging control chip itself.

[0075] After the conventional charging control chip 204 determines that the voltage to be charged transmitted from the second conventional charging interface 105 of the charging device 100 to the first conventional charging interface 202 of the electronic atomization device 200 is greater than or equal to the preset slow charging voltage threshold, the conventional charging control chip 204 can prohibit the voltage to be charged from being transmitted to the rechargeable battery 203 through the conventional charging control chip 204 itself.

[0076] In the embodiment of the present application, when the electronic atomization device 200 needs to be fast charged, the first fast charging interface 201 of the electronic atomization device 200 is electrically connected to the second fast charging interface 104 of the external charging device 100, and then the second fast charging interface 104 sends the fast charging information to the first fast charging interface 201, and transmits the fast charging voltage to the first fast charging interface 201. After receiving the fast charging information and the fast charging voltage, the first fast charging interface 201 directly transmits the fast charging voltage to the rechargeable battery 203 for fast charging. Since the electronic atomization device 200 is not provided with a fast charging charging protection circuit, nor is a fast charging protocol embedded, but is directly fast charged by electrically connecting the charging protection circuit provided with a fast charging and the charging device 100 embedded with a fast charging protocol, the circuit structure in the electronic atomization device 200 is simplified, charging is fast, and miniaturization production can be achieved, and the manufacturing cost is low. When the electronic atomization device 200 needs to be charged conventionally, the first conventional charging interface 201 is electrically connected to the second conventional charging interface 105 of the external charging device 100. The conventional charging control chip 204 in the electronic atomization device 200 first determines whether the voltage to be charged from the second conventional charging interface 105 is less than the preset slow charging voltage threshold preset in the electronic atomization device 200. If so, the conventional charging control chip 204 controls the first conventional charging interface 202 to transmit the conventional charging voltage transmitted from the charging device 100 to the rechargeable battery 203, thereby performing conventional charging on the rechargeable battery 203. If not, the conventional charging control chip 204 prohibits the voltage to be charged from being transmitted to the rechargeable battery 203 through the conventional charging control chip 204 itself. In this way, the same electronic atomization device 200 can realize multiple charging methods of fast charging and conventional charging according to the needs of fast charging or slow charging, providing users with more choices of charging methods. The charging methods are flexible and diverse, bringing greater convenience to users, not only saving the utilization of resources, but also making the product more environmentally friendly.

[0077] Reference Figure 4 In this embodiment, the charging method of the electronic atomization device 200 can also only perform the following steps:

[0078] 401. When the first conventional charging interface is electrically connected to the second conventional charging interface of the external charging device, the conventional charging control chip determines whether the charging voltage transmitted from the second conventional charging interface to the first conventional charging interface is less than a preset slow charging voltage threshold preset in the electronic atomization device;

[0079] If yes, execute step 402; if no, execute step 403.

[0080] 402. The conventional charging control chip controls the first conventional charging interface to transmit the conventional charging voltage transmitted by the charging device to the rechargeable battery, thereby performing conventional charging on the rechargeable battery;
