Electronic cigarette cartridge with closed system

Abstract

The invention discloses an electronic cigarette cartridge with a closed system. The electronic cigarette cartridge is characterized in that a through hole is axially formed in the center of a housing, and a cavity is formed by the peripheral wall of the through hole and the outer wall of the housing; an inner wall cavity is arranged in the opening in the left end part of the cavity, and the left end of the inner wall cavity is in close fit with the outer wall; a first air hole is formed in the right end of the inner wall cavity, and a liquid outlet hole is formed in the middle wall of the inner wall cavity; a pressure spring is arranged at the combination part of the middle part and the right end part of the inner wall cavity in a propping manner, an inner core is arranged on the left end of the pressure spring in a propping manner, and a second air hole is axially formed in the inner core; the inner core and the inner wall cavity are in close fit; sealing covers are arranged on the left ends of the inner core and the inner wall cavity in a buckling manner; the sealing covers and the housing are in interference fit; a third air hole is formed in the sealing holes; the first air hole, the second air hole and the third air hole are communicated with the through hole. The electronic cigarette cartridge has the advantages of 1) closure of liquid smoke: liquid smoke is closed in a container, related personnel cannot be contacted with the liquid smoke neither in use process or in storage process, so that the use and storage safety can be guaranteed; and 2) strong replicability: different tastes of electronic cigarette cartridges can be conveniently changed under the condition of not influencing the whole quality of an electronic cigarette.

Description
