Beschreibung
Zusammenfassung:An air flow sensor (100) and an electronic cigarette (1000), the air flow sensor (100) comprising a sensing circuit module (1), a first sealing member (2), and a second sealing member (3), the sensing circuit module (1) comprising a circuit board (11) and a sensing device (12), the circuit board (11) comprising a first surface (111) and a second surface (112) arranged in opposite positions, the first sealing member (2) covering at least part of the first surface (111), and the second sealing member (3) covering at least part of the second surface (112). The first sealing member (2) and the circuit board (11) define a first accommodating cavity (a1), the sensing device (12) being accommodated in the first accommodating cavity (a1), and the first sealing member (2) comprising a first waterproof air-permeable part (p1). A connecting solder pad (114) electrically connected to the sensing device (12) is arranged on the circuit board (11), the air flow sensor (100) being connected to other circuit devices by means of the connecting solder pad (114), and the connecting solder pad (114) not being covered by the first sealing member (2) or the second sealing member (3). The present air flow sensor (100) can better block fluids such as water and e-liquid from flowing into the air flow sensor (100), being convenient to manufacture and having good sealing performance.
