Specifically, for the reader to fully understand the technical solution of the present application, please refer to fig. 2, in which the charging device 200 in fig. 2 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, 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.
In the charging apparatus 200, the charging protection structure 203 is a charging protection circuit for protecting the rechargeable battery 107 in the electronic atomizing device 100 from damage during rapid charging or regular charging of the electronic atomizing device 100. That is, the charging protection structure 203 in the charging apparatus 200 is provided with both a protection circuit for quick charging and a protection circuit for normal charging.
As can be seen from fig. 2, the charging protection structure 203, i.e., the charging protection circuit, which is originally typically provided in the electronic atomizing device 100, is removed and provided in the charging apparatus 200. And, the quick charge protocol is also embedded in the second control chip 201 of the charging device 200. In this way, when the fast charging is performed, the fast charging protocol is matched with the charging protection structure 203, and the fast charging of the electronic atomizing apparatus 100 is performed through the fast charging interface 204 of the charging device 200. Whereas, after the charging interface 101 is electrically connected to the quick charging interface 204 in the charging apparatus 200, the electronic atomizing device 100 operates as follows.
First, the charging interface 101 is used to access a 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.
Next, the voltage detection circuit 102 is configured to detect a voltage value of the charging voltage from the external charging device 200, and transmit the voltage value to the first control chip 103.
Since the charging interface 101 of the electronic atomization device 100 is connected to the quick charging interface 204 of the charging apparatus 200 at this time, the voltage detection circuit 102 detects a large charging voltage and a large charging current required for quick charging, and then sends the detection results to the first control chip 103.
The first control chip 103 is configured to determine whether the voltage value is greater than or equal to a preset voltage threshold preset in the electronic atomizing device 100. When the first control chip 103 determines that the voltage value is greater than or equal to the preset voltage threshold, the quick charge switch device 104 is turned on while the conventional charge switch device 105 is kept turned off. The preset voltage threshold is usually preset in a memory (not shown) of the electronic atomizing device.
When the quick charge switching device 104 is in the on state, the charging interface 101 is configured to directly and quickly transmit the quick charge charging voltage to the rechargeable battery 107.
As can be seen from the above, the electronic atomization device 100 according to the embodiment of the application has a simple circuit structure, and the fast charging protocol and the fast charging protection circuit are removed, so that the charging is faster.
As can be seen from fig. 2, the fifth terminal of the charging interface 101 is grounded, and the third terminal of the rechargeable battery 107 is also grounded, so that when the charging interface of the electronic atomizing device 100 is electrically connected to the quick charging interface 204 of the charging apparatus 200, the charging interface 101 of the electronic atomizing device 100, the quick charging switch 104 and the rechargeable battery 107 form an electrical circuit, and the rechargeable battery 107 is charged under the control of the first control chip 103.
On the side of the charging device 200, since the handshake protocol of the fast charging is embedded in the second control chip 201 of the charging device 200, and the handshake protocol of the fast charging is adapted to the fast charging interface 204, the fast charging voltage of the fast charging is 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, so as to realize fast charging of the rechargeable battery 107 in the electronic atomization device 100.
In the embodiment of the present application, the fast charge voltage may be 9 v, 12 v or 22 v, which is not limited herein.
When the electronic atomizing apparatus 100 needs to be charged conventionally, the charging interface 101 may 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 atomizing apparatus 100, the conventional charging switch apparatus 105, the conventional charging circuit 105 and the rechargeable battery 107 form a circuit.
The working principle during conventional charging is as follows:
First, the voltage detection circuit 102 detects a normal charging voltage transmitted from the charging device 200, and then transmits 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 according to the voltage value sent by the voltage detection circuit 102.
When the first control chip 103 determines that the voltage value is smaller than the preset voltage threshold, the first control chip 103 is further configured to turn on the conventional charge switch device 105 while keeping the quick charge switch device 104 turned off.
Then, the normal charging circuit is used at this time to transmit the charging voltage transmitted from the charging interface 101 to the rechargeable battery 107 when the normal charging switch device 105 is in the on state.
The conventional charging circuit 105 limits current and voltage, and only allows a voltage of not more than 5 v to pass through, thereby charging the rechargeable battery 107.
On the charging device 200 side, when the second control chip 201 receives the information that the electronic atomization device 100 is electrically connected with the conventional charging interface 205 of the charging device 200, the second control chip 201 controls the charging structure 202 and the charging protection structure 203 inside the second control chip 201 to transmit the conventional voltage to the electronic atomization device 100 through the conventional charging interface 205, so as to realize conventional charging of the rechargeable battery 107 of the electronic atomization device 100.
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.
In the embodiment of the present application, the charging interface 101 may be a TYPE-a interface, a TYPE-B interface or a TYPE-C interface, or may be a dual-contact interface, which is not limited herein.
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 limited herein.
In the embodiment of the application, the rapid charging protocol and the charging protection circuit are removed from the electronic atomization device 100, and the rapid charging interface and the conventional charging interface are integrated into one interface, so that the structure of the electronic atomization device is further simplified, and the miniaturization and the low price of products are realized.

When the voltage value is the large voltage for quick charge, the second main control chip controls the inverter U1 to be electrically connected with the control switch K2, and the control inverter U1 is disconnected from the control switch K3. When the voltage value is a small voltage for normal charging, the second main control chip controls the electric connection of the inverter U1 and the control switch K3, and the control inverter is electrically connected with the control switch K2.
