AI Technical Summary

Technical Problem

The existing connection method between the cigarette cartridge and the cigarette rod has the problems of high cost and low disassembly and assembly efficiency, especially the magnet connection is easy to fall off, the threaded structure is easy to damage, and the snap-on structure is complicated, which leads to increased parts cost and assembly cost.

Method used

A sealing ring is set on the cigarette rod body to form a groove. The cigarette cartridge body is pressed against the sealing ring and forms a sealed cavity with the groove. The air pressure in the sealed cavity is reduced by the decompression component, and the external air pressure is used to achieve a firm connection between the cigarette rod and the cigarette cartridge. The air pressure difference is used to separate them during disassembly.

Benefits of technology

It achieves low-cost connection without the need for additional magnetic structures, improves disassembly and assembly efficiency, simplifies the operating process, and reduces parts costs and assembly complexity.

Abstract

The present invention relates to the technical field of electronic cigarettes, and specifically discloses a connection structure between a cigarette cartridge and a cigarette rod, an electronic cigarette, and a method for connecting a cigarette cartridge and a cigarette rod. The connection structure between the cigarette cartridge and the cigarette rod includes a cigarette rod body, a cigarette cartridge body, and a decompression assembly. A sealing ring is provided on the first surface of the cigarette rod body, and the first surface of the cigarette rod body and the sealing ring are arranged to form a groove; the cigarette cartridge body can be pressed against the sealing ring, and the second surface of the cigarette cartridge body is sealed at the opening of the groove, and the second surface and the groove form a sealed cavity; the decompression assembly is used to reduce the air pressure in the sealed cavity. With the help of the above arrangement, the external air pressure is greater than the air pressure in the sealed cavity. Under the action of the external air pressure, the cigarette rod body and the cigarette cartridge body are firmly connected, without the need for an additional magnetic structure, and the cost is low. When disassembling, it is directly pulled with force. When the pulling force between the cigarette rod body and the cigarette cartridge body is greater than the adsorption force generated by the pressure difference between the inside and outside of the sealed cavity, the cigarette rod body can separate the cigarette rod body and the cigarette cartridge body, and the disassembly and assembly efficiency is high.
