[0134] Third embodiment

[0135] See Figure 14 , Figure 14 It is a circuit module diagram of the electronic device of the third embodiment of the present application. This embodiment is similar to the first, second embodiment, and thus the portion not described in this embodiment can refer to the foregoing embodiment, the embodiment and the first, and first, The main difference between the second embodiment is that the battery protection module 2100 also includes a first ship to exit end QC1.

[0136] Please refer to Figure 14 and Figure 15 In this embodiment, the second ship's exit end QC2 does not directly connect the system end VM. Specifically, the battery protection module 2100 also includes a first ship to exit end QC1, and the first ship running end QC1 is electrically connected to the second ship's exit end Qc2, and the first ship is running QC1 to connect the first non-door 2121. The input terminal, the output of the first non-door 2121 connects the input terminal of the ...

Abstract

The invention provides a battery protection circuit which comprises a battery protection module and a first switch unit, the battery protection module comprises an over-discharge voltage protection unit, a discharge over-current protection unit, a reference voltage generation unit and a logic control unit, and a first power supply end and a first power supply grounding end are respectively used for being electrically connected with a battery. The logic control unit is electrically connected with the first switch unit for controlling on or off of the first switch unit, and the first switch unit is used for controlling the battery to supply power to the system circuit; the battery protection circuit further comprises an approach detection module, the approach detection module is used for being electrically connected with the approach unit, the approach detection module is further electrically connected with the battery protection module, the battery protection module has a shipping mode, and in the shipping mode, the first switch unit is switched off and the battery protection module is in a zero-power-consumption mode. When the battery protection module is in the shipping mode, the proximity detection module is in the normal working mode. The invention further provides a battery assembly and an electronic cigarette.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery protection circuit, a battery assembly and an electronic cigarette. Background technique [0002] Existing electronic cigarettes usually consist of two parts: a device and a pod with an atomizer. The pod stores e-liquid, and the atomizer atomizes the e-liquid when the atomizer is working; the device is equipped with a battery, a system circuit, and an airflow sensor. (such as a microphone), the battery is electrically connected to the system circuit, and the system circuit is electrically connected to the atomizer and the air flow sensor respectively. When the air flow sensor detects the air flow caused by the user smoking, the system circuit judges that the user has a smoking action, and the system The circuit controls the output power of the atomizer, and the atomizer heats and atomizes the e-liquid to achieve smoke. [0003] The inventors of the present ...
