Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a multiple sealing structure between a cigarette cartridge and a main unit plug-in cavity, and an electronic cigarette provided with the multiple sealing structure. Background Art

[0002] Electronic cigarettes are electronic products that replace traditional cigarettes. They mainly use electric heating core components to heat the smoke oil into aerosol vapor for users to consume. Existing electronic cigarettes mainly include two types of electronic cigarettes: integrated and split. The integrated electronic cigarette is composed of the suction mouth, oil tank, atomizer core, control panel, sensor microphone and battery assembled in the shell. The airflow channel of the integrated electronic cigarette enters from the air inlet of the shell and exits from the suction mouth. It is relatively closed, and the consistency of suction resistance and taste is high. As for the split electronic cigarette, it mainly includes an electronic cigarette host and a cigarette cartridge. The electronic cigarette host is provided with a plug-in cavity, and the cigarette cartridge is plugged into the plug-in cavity. The bottom of the cigarette cartridge is connected to the bottom of the plug-in cavity through a contact electrode terminal to realize the connection of the atomizer core with the control panel and the battery power supply. The working airway of the split cartridge electronic cigarette is provided with an air inlet hole in the main body shell. The gas enters the main body shell from the air inlet hole to trigger the sensor microphone, and then the gas enters the atomizer core in the cigarette cartridge from the air outlet hole at the bottom of the plug-in cavity to realize atomization output. Due to the production tolerances of the cartridge shell and the main body shell, there are errors in the processed plane, and there will be a gap between the outer wall of the cartridge shell and the inner wall of the plug-in cavity. When the electronic cigarette is in use, air will enter the bottom of the cartridge from the gap and then enter the atomization core, thus affecting the inhalation resistance of the electronic cigarette. The amount of gas entering the main body shell to trigger the sensor microphone will also change, which will affect the sensitivity of the sensor microphone, thereby affecting the atomization effect and the taste of the smoke. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this solution proposes a multiple sealing structure between the cigarette cartridge and the main unit plug-in cavity. The multiple sealing structure is arranged on the plug-in cavity of the electronic cigarette main unit of the split electronic cigarette for plugging the cigarette cartridge, so that when the cigarette cartridge is plugged into the plug-in cavity of the electronic cigarette main unit for use, the external air is blocked from entering the interior of the cigarette cartridge through the gap between the outer wall of the cigarette cartridge and the inner wall of the plug-in cavity.

[0004] The technical solution adopted by the utility model is: a multiple sealing structure between a cigarette cartridge and a main unit plug-in cavity, comprising a soft rubber sealing sleeve, the soft rubber sealing sleeve being in the shape of a ring with upper and lower openings as a whole, the upper port of the soft rubber sealing sleeve being provided with a triple sealing structure, the triple sealing structure comprising a first edge portion extending horizontally inwardly along the upper port, a second edge portion extending obliquely upward inwardly along the upper port, and a third edge portion extending obliquely upward outwardly along the upper end of the second edge portion, a groove ring portion being formed on the outer sides of the second edge portion and the third edge portion, and an inner convex ridge ring portion being formed on the inner sides of the second edge portion and the third edge portion.

[0005] Furthermore, the included angle between the second edge portion and the first edge portion is 30 degrees to 60 degrees, and the included angle between the third edge portion and the second edge portion is 60 degrees to 90 degrees.

[0006] Furthermore, the outer wall of the soft rubber sealing sleeve is provided with at least one raised sealing ring portion along the circumference of the soft rubber sealing sleeve.

[0007] Furthermore, the soft rubber sealing sleeve is made of silicone material and is integrally injection-molded.

[0008] An electronic cigarette is a split electronic cigarette, comprising a cartridge and an electronic cigarette host, the electronic cigarette host is provided with an electronic cigarette cartridge plug-in cavity, a cartridge connecting seat is provided in the electronic cigarette cartridge plug-in cavity, the cartridge connecting seat is provided with a multiple sealing structure between the cartridge and the host plug-in cavity as described in the above technical solution, the bottom edge of the cartridge forms a step position, and the bottom of the cartridge and the step position are connected to the multiple sealing structure.

[0009] When in use, the cigarette cartridge is inserted into the electronic cigarette cartridge insertion cavity, the bottom edge of the cigarette cartridge and the first edge portion form a first seal, the side wall of the step position at the bottom of the cigarette cartridge and the inner convex ridge ring portion form a second seal, and the bottom wall of the step position at the bottom of the cigarette cartridge and the upper end of the third edge portion form a third seal.

[0010] The beneficial effects of the utility model are as follows: since the actual height of the electronic cigarette cartridges produced will have a deviation of 0.2mm, and the height position of the cartridge connection seat of the host will also have a deviation of 0.2mm. In order to achieve the same sealing effect between the cartridges and the cartridge plug-in cavity of the electronic cigarettes produced in large quantities, a step is formed at the bottom edge of the cartridge. When the cartridges and the cartridge connection seat are connected by magnet adsorption, the third edge and the second edge of the upper port of the soft rubber sealing sleeve of the multiple sealing structure designed in this scheme provide sufficient elasticity, while ensuring the reliable connection between the cartridge electrode and the electrode of the connection seat, as well as the structure of the first edge, the second edge, and the third edge of the upper port of the soft rubber sealing sleeve designed in this scheme, realize the triple sealing connection between the bottom edge of the cartridge and the upper port of the soft rubber sealing sleeve. This solves the problem that the existing bottom of the cartridge and the plug-in cavity have poor sealing effect, which affects the suction resistance, the sensitivity of the microphone head and the taste. While achieving the seal between the bottom of the cigarette cartridge and the plug-in cavity, it also solves the problem of height deviation between the cigarette cartridge and the cigarette cartridge connecting seat after production. The sealing structure of the upper port of the soft rubber sealing sleeve has sufficient elasticity, which can achieve both sealing and sufficient elasticity to achieve reliable connection between the cigarette cartridge electrode and the electrode of the connecting seat.
