Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette with a visible oil tank and no central column. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes and have the same appearance as cigarettes. Electronic cigarettes can vaporize liquid containing nicotine through an atomizer for users to inhale. In existing electronic cigarettes, the atomizer core and airway are mostly set in the center of the oil cup. In order to fix the heating mesh and oil-guiding cotton, the heating wire bracket needs to be set in the center. It can not only act as an airway but also connect and fix the atomizer core. This cannot avoid the long-term immersion and contact between the metal heating wire bracket and the tobacco oil.

[0003] It can be seen that the metal heating wire bracket in the existing electronic cigarettes is in long-term contact with the smoke oil, and the long-term contact between the metal bracket and the weakly acidic smoke oil will cause the smoke oil to change color. After inhaling, the taste will become lighter and have an odor, which results in a poor user experience. On the other hand, most of the existing electronic cigarettes use a closed oil tank, and users cannot check the amount of smoke oil in the oil tank, which makes users prone to smoke oil anxiety when using electronic cigarettes, especially when they need to carry electronic cigarettes out.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] like Figure 1-4As shown, a center column-free visible oil tank electronic cigarette includes a shell 1, a suction nozzle 2 is installed at one end of the shell 1, an oil cup 3 is fixedly installed in the shell 1, an oil storage chamber 31 is arranged in the oil cup 3, the oil storage chamber 31 is used to store smoke oil, and a starting airway 32 and a suction airway 33 are respectively provided on both sides of the oil storage chamber 31, the starting airway 32 and the suction airway 33 are respectively separated from the oil storage chamber 31, so that the smoke oil in the oil storage chamber 31 will not flow into the starting airway 32 and the suction airway 33, and the starting airway 32 and the suction airway 33 are respectively connected to the suction nozzle 2. A heating core 4 is installed in the oil storage chamber 31. The heating core 4 is used to heat the tobacco oil and atomize it into an aerosol. The heating core 4 is sealed and abutted against the inner wall of the oil storage chamber 31, thereby preventing the tobacco oil from leaking from the installation position of the heating core 4. An oil cup lower seal 5 is provided at the end of the oil cup 3 away from the suction nozzle 2. The oil cup lower seal 5 abuts against the heating core 4. The heating core 4 is limited and fixed in the oil storage chamber 31 by the oil cup lower seal 5 to prevent the heating core 4 from shifting and reduce the possibility of oil leakage. A suction air groove 51 and a start-up air groove 52 are provided in the oil cup lower seal 5. The suction air groove 51 is connected to the heating core 4 and the suction airway 33 respectively, and the start-up air groove 52 is connected to the start-up airway 32.

[0025] During the electronic cigarette inhalation process, the user inhales through the mouthpiece 2, so that negative pressure is generated inside the shell 1, and external air will enter the shell 1. Part of the airflow flows through the start switch 9 to trigger the start signal, so that the heating core 4 works to heat the tobacco oil into aerosol. After the start airflow flows out of the start switch 9, it will flow into the start air groove 52, and then into the start air duct 32, and finally be inhaled by the user; another part of the airflow will flow through the suction air groove 51, thereby mixing with the atomized aerosol, and then flow into the suction air duct 33, and finally be inhaled by the user from the mouthpiece 2, completing the electronic cigarette inhalation process.

[0026] The electronic cigarette sets the suction airway 33 and the starting airway 32 on the side of the oil storage chamber 31 respectively, and installs the heating core 4 into the oil storage chamber 31, so that it is not necessary to install a central column bracket to fix the heating core 4, avoiding the problem of poor suction taste caused by long-term contact between the metal bracket and the smoke oil, and improving the user's usage experience.

[0027] In order to enable the user to know the amount of oil in the oil storage chamber 31 in real time, an observation hole 101 is provided on the side wall of the housing 1, and a visual window 34 is provided on the side wall of the oil cup 3 at a position corresponding to the observation hole 101. During use, the user can check the amount of oil in the oil storage chamber 31 through the observation hole 101 and the visual window 34, thereby solving the problem of oil anxiety when carrying the device outside, improving practicality, and greatly improving the user's use experience.

[0028] In this embodiment, the oil cup 3 is made of a transparent material, so that the user can check the amount of oil in the oil storage chamber 31. The visual window 34 protrudes from the outer wall of the oil cup 3, and the visual window 34 is limitedly abutted against the observation hole 101; by setting the visual window 34 as an outward convex structure, and by the cooperation between the visual window 34 and the observation hole 101, the oil cup 3 and the housing 1 can be installed and limited, so that the two are connected and fixed, and the user can check the amount of oil in the oil storage chamber 31 more conveniently, thereby improving the stability of the structure and the practicality of use.

[0029] There are two observation holes 101, and the two observation holes 101 are symmetrically arranged on the front and rear side walls of the housing 1, and the visual windows 34 are arranged one-to-one corresponding to the observation holes 101. By setting two observation holes 101, the user can check the amount of oil in the oil storage chamber 31 from the front or the back, and the symmetrical arrangement also makes the appearance of the electronic cigarette more beautiful.

[0030] The heating core 4 includes a heating core seal 41 and a ceramic heating element 42. The heating core seal 41 is wrapped around the periphery of the ceramic heating element 42, and the heating core seal 41 is sealed against the inner wall of the oil storage cavity 31. The heating core seal 41 is abutted against the lower seal 5 of the oil cup. By setting the heating core seal 41, the ceramic heating element 42 is limited and fixed in the oil storage cavity 31, which improves the structural stability of the electronic cigarette and can also reduce the possibility of oil leakage.

[0031] An oil cup upper seal 6 is provided at one end of the oil cup 3 near the suction nozzle 2. An oil filling hole 35 is provided on the oil cup 3. The oil filling hole 35 is connected to the oil storage chamber 31. The oil filling hole 35 is used to easily inject tobacco oil into the oil storage chamber 31. The oil cup upper seal 6 is sealed and connected to the oil filling hole 35. The oil cup upper seal 6 blocks the oil filling hole 35 to prevent oil leakage during use. Ventilation holes 36 are provided on the oil cup upper seal 6 at positions corresponding to the starting airway 32 and the suction airway 33. The vents 36 are provided to enable both the starting airway 32 and the suction airway 33 to be connected to the suction nozzle 2, thereby ensuring the stability of the electronic cigarette suction.
