Disclosed is a smoking habit corrector having a liquid inflow preventing member. According to an embodiment of the present invention, the smoking habit corrector comprises: a pipe having open both ends, and having a space formed therein； a lighting unit including a light emitting diode accommodated in the pipe and exposed to one end of the pipe, and a control circuit； a battery accommodated in the pipe, and connected to the lighting unit to supply power； a smoke suction pipe having a passage formed therein, having an open hole penetrating a passage at one end thereof, and having a cut groove formed on an outer circumferential surface thereof； a heating member accommodated inside the pipe, coupled to penetrate the smoke suction pipe, and heated by the power of the battery； a cartridge accommodated inside the pipe, wound around the outside of the heating member and the smoke suction pipe, and containing liquid； a sealing member for blocking and sealing a gap between an outer circumferential surface of the smoke suction pipe and an inner circumferential surface of the cartridge； and a liquid inflow preventing member inserted into the opening hole of the smoke suction pipe, and coupled to an opening of the other end of the pipe to allow a mouth to be in contact therewith. According to the present invention, the smoking habit corrector is hygienic and has no repulsion so a pleasant texture can be provided since internal liquid is prevented from being leaked during suction, and has a benefit for health since a vitamin component included in smoke can be sucked.COPYRIGHT KIPO 2018액상 유입 방지부재를 구비한 흡연습관 교정기가 개시된다. 실시예에 따르면, 양단이 개구되고 내부에 공간이 형성된 관체； 관체의 내부에 수용되며 관체의 일단에 노출되는 발광다이오드와 제어회로로 구성되는 점등부； 관체의 내부에 수용되며, 점등부에 연결되어 전원을 공급하는 배터리； 내부에 통로가 형성되며, 일단에는 통로에 통하는 개구공이 형성되고, 외주면에 절개홈이 형성된 연기흡입관； 관체의 내부에 수용되며, 연기흡입관을 관통하여 결합되며, 배터리의 전원에 의해 가열되는 발열부재； 관체의 내부에 수용되며, 발열부재 및 연기흡입관의 외측에 권취되고, 액체가 함유된 카트리지；를 포함하고, 연기흡입관의 외주면과 카트리지의 내주면 사이의 틈새를 막아 밀봉시키는 밀봉부재；를 포함하는 흡연습관 교정기에 있어서, 연기흡입관의
