Document Type and Number:
WIPO Patent Application WO/2018/129979
Kind Code:
A1
Abstract:
An electronic cigarette and a battery protection circuit thereof. The battery protection circuit (10) is used for connecting with a battery (90). The battery protection circuit (10) has a first connecting end (101) and a second connecting end (102), the first connecting end (101) being connected with one end of a battery (90) and the second connecting end (102) being connected with the other end of the battery (90). The battery protection circuit (10) further comprises a third connecting end (103), a fourth connecting end (104), a fifth connecting end (105), and a sixth connecting end (106), the third connecting end (103) and the fourth connecting end (104) being both used for connecting with a positive voltage network, and the fifth connecting end (105) and the sixth connecting end (106) being both used for connecting with a ground network. When the first connecting end (101) is connected with the positive electrode of the battery and the second connecting end (102) is connected with the negative electrode of the battery, the third connecting end (103) is in communication with the first connecting end (101) and the fifth connecting end (105) is in communication with the second connecting end (102). When the first connecting end (101) is connected with the negative electrode of the battery and the second connecting end (102) is connected with the positive electrode of the battery, the sixth connecting end (106) is in communication with the first connecting end (101) and the fourth connecting end (104) is in communication with the second connecting end (102). The electronic cigarette and the battery protection circuit can prevent inverse connection with a battery.
