[0002] Electronic cigarettes are a new type of electronic product that looks similar to ordinary cigarettes and has the same taste as cigarettes. Since electronic cigarettes heat the oil through the core to produce smoke, compared with traditional cigarettes, electronic cigarettes do not require combustion when inhaled, so electronic cigarettes are safer than traditional cigarettes.

[0003] During the use of electronic cigarettes, the outside air enters the electronic cigarette and mixes with the hot e-liquid heated and atomized by the atomizer, so that the airflow entering the electronic cigarette cartridge is maintained at a high temperature. When these high-temperature airflows encounter the lower-temperature components in the suction airway, part of the mist in the high-temperature airflow condenses to form condensate. The airway of existing electronic cigarettes lacks a device that can absorb condensate. As the condensate accumulates, the condensate may fall into the electronic cigarette, causing a short circuit in the internal circuit of the electronic cigarette and burning the circuit board. Moreover, the condensate attached to the airway is also easily inhaled into the mouth of the user during the user's inhalation process, affecting the inhalation taste of the electronic cigarette and giving the user a very bad user experience.

[0022] 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.

[0023] like Figure 1-3As shown, an electronic cigarette cartridge includes a cartridge housing 1 and an end cap 2, the end cap 2 is fixedly connected to one end of the cartridge housing 1, an oil filling cavity 3 is arranged in the cartridge housing 1, the oil filling cavity 3 is composed of a sealed cavity formed by the cartridge housing 1 and the end cap 2 after being installed and fixed, an atomizing core is arranged in the cartridge housing 1, the atomizing core is fixedly connected to the cartridge housing 1 and the end cap 2 respectively, and the atomizing core is used to heat the atomized cigarette oil. A mouthpiece 4 is arranged at one end of the cartridge housing 1, and the mouthpiece 4 is connected to the atomizing core. When assembling the electronic cigarette cartridge, first install the atomizer core into the cartridge shell 1, then inject the oil into the oil filling cavity 3, and then seal and fix the end cover 2 to the cartridge shell 1 to prevent the oil from leaking. When the electronic cigarette is in use, install the electronic cigarette cartridge on the power supply rod of the electronic cigarette. When inhaling, the user inhales through the mouthpiece 4, and the oil in the oil filling cavity 3 flows into the atomizer core. The atomizer core heats the oil and atomizes it into an aerosol. The atomized aerosol flows out to the mouthpiece 4 with the user's inhalation airflow and is finally inhaled by the user, completing the inhalation process of the electronic cigarette.

[0024] The atomizer core includes a mounting bracket 5, one end of which is fixedly connected to the cartridge housing 1, and the other end is fixedly connected to the end cap 2. The mounting bracket 5 is a hollow tubular structure, one end of which is connected to the mouthpiece 4, and the other end is connected to the air inlet on the end cap 2. A heating core is arranged in the mounting bracket 5, and the heating core is used to heat the atomized tobacco oil and atomize the liquid tobacco oil into an aerosol. A liquid absorbent cotton 6 is arranged above the heating core, and the liquid absorbent cotton 6 is fixedly connected to the mounting bracket 5. The liquid absorbent cotton 6 is used to absorb the condensed liquid generated in the airway during the suction process; the liquid absorbent cotton 6 is provided with a penetrating airway hole 61, and the airway hole 61 is connected to the inner hole of the mounting bracket 5, so that when suction is taken, the aerosol atomized by the heating core can flow out through the airway hole 61, and then flow out of the mouthpiece 4 to be sucked out by the user. By arranging the absorbent cotton 6 above the heating core, the condensed liquid generated in the airway during the suction process can be absorbed, thereby preventing the user from inhaling the condensed liquid during the suction, improving the suction taste of the electronic cigarette and enhancing the user's usage experience.

[0025] In order to prevent the condensate on the absorbent cotton 6 from dripping onto the heating core, a spacer 7 is provided between the absorbent cotton 6 and the heating core. The spacer 7 is fixedly connected to the mounting bracket 5, and the upper end surface of the spacer 7 is in contact with the absorbent cotton 6. The spacer 7 is used to prevent the condensate in the absorbent cotton 6 from flowing onto the heating core. Through holes are provided at the corresponding positions of the spacer 7 and the airway hole 61, so as to facilitate the passage of the atomized aerosol and realize the suction function of the electronic cigarette. In this embodiment, the spacer 7 is made of heat-conducting metal material; when the electronic cigarette is working, the spacer 7 can transfer the heat on the heating core to the absorbent cotton 6, thereby promoting the evaporation of the condensate in the absorbent cotton 6, increasing its cyclic absorption of the condensate, and extending the service life of the electronic cigarette. In other embodiments, the spacer 7 can also be made of other materials, as long as it can be ensured that the condensate on the absorbent cotton 6 can be blocked from flowing downward.

[0026] The heating core includes a first oil-absorbing cotton 8 and a heating element 9. The first oil-absorbing cotton 8 is limitedly connected to the inner wall of the mounting bracket 5, and the first oil-absorbing cotton 8 is connected to the oil filling cavity 3, so that the tobacco oil in the oil filling cavity 3 can enter the interior of the mounting bracket 5. The heating element 9 is limitedly installed in the first oil-absorbing cotton 8, and the heating element 9 is used to heat the atomized tobacco oil. In this embodiment, the heating element 9 is a heating wire made of metal material. In other embodiments, the heating element 9 can also use other devices that can achieve electric heating, such as: ceramic heating element, etc.; when inhaling, the tobacco oil enters the interior of the mounting bracket 5 from the oil filling cavity 3 through the first oil-absorbing cotton 8, and then flows to the heating element 9. The heating element 9 works to heat the tobacco oil and atomize it into an aerosol, so that the tobacco oil changes from liquid to gas, so that the user can inhale it.

[0027] Two contact electrodes 10 are installed on the end cover 2, and the two contact electrodes 10 are electrically connected to the heating element 9 respectively. The contact electrodes 10 are used to connect to the power supply on the electronic cigarette rod, so that the heating element 9 can be energized, so that the heating element 9 can generate heat to atomize the tobacco oil into aerosol during the inhalation process.

[0028] In order to limit the installation of the heating element 9 in the first oil-absorbing cotton 8, an installation limit ring 11 is installed in the installation bracket 5. The installation limit ring 11 is inserted into the installation bracket 5 and is fixedly connected to the inner wall of the installation bracket 5. The installation limit ring 11 is fixedly connected to the heating element 9. The installation limit ring 11 is used to limit and fix the heating element 9 in the first oil-absorbing cotton 8, thereby improving the stability of the structure and ensuring that the heating element 9 can heat the tobacco oil on the first oil-absorbing cotton 8 and atomize it into aerosol when working.

[0029] The second oil-absorbing cotton 12 is sleeved on the outer wall of the mounting bracket 5. The second oil-absorbing cotton 12 is connected to the first oil-absorbing cotton 8. The outer side of the second oil-absorbing cotton 12 extends into the oil filling cavity 3 and directly contacts the smoke oil. The second oil-absorbing cotton 12 absorbs the smoke oil and then conducts it to the first oil-absorbing cotton 8, thereby introducing the smoke oil into the interior of the mounting bracket 5. The two ends of the second oil-absorbing cotton 12 are respectively installed with oil-absorbing cotton fixing rings 13. The two oil-absorbing cotton fixing rings 13 are respectively sleeved on the periphery of the mounting bracket 5 and fixedly connected to the mounting bracket 5. The oil-absorbing cotton fixing rings 13 are respectively abutted against the two ends of the second oil-absorbing cotton 12. By installing the oil-absorbing cotton fixing rings 13 on the two ends of the second oil-absorbing cotton 12, the second oil-absorbing cotton 12 is limitedly fixed on the mounting bracket 5, thereby improving the stability of the structure and ensuring that the smoke oil can smoothly enter the interior of the mounting bracket 5.

[0030] The outer periphery of the second oil-absorbing cotton 12 is sleeved with an atomizer core housing 14, and an oil-passing hole 15 is provided on the atomizer core housing 14. Both ends of the atomizer core housing 14 are respectively connected to the oil-absorbing cotton fixing ring 13. By providing the atomizer core housing 14, on the one hand, the second oil-absorbing cotton 12 can be limited and fixed, and the tobacco oil in the oil filling cavity 3 can flow into the second oil-absorbing cotton 12 through the oil-passing hole 15; on the other hand, by providing the atomizer core housing 14, the second oil-absorbing cotton 12 can be prevented from being in contact with the tobacco oil in the oil storage cavity as a whole, thereby achieving the purpose of controlling the oil guide rate, avoiding excessive consumption of tobacco oil, and extending the service life of the electronic cigarette.

[0031] Working principle:

[0032] Before use, the electronic cigarette cartridge is installed on the cigarette rod, and the contact electrode 10 is electrically connected to the power supply in the cigarette rod. When inhaling, the user inhales through the cigarette holder 4, thereby triggering the start signal; the tobacco oil flows from the oil filling cavity 3 into the oil hole 15 and then flows into the second oil-absorbing cotton 12; then flows into the first oil-absorbing cotton 8 and enters the inside of the mounting bracket 5; the heating element 9 is powered on to heat the tobacco oil on the first oil-absorbing cotton 8 and atomize it into an aerosol. The atomized aerosol will flow toward the cigarette holder 4 along with the user's inhalation airflow, thereby flowing into the airway hole 61, and then flows out of the mounting bracket 5, and finally flows out of the cigarette holder 4 to be inhaled by the user, completing the inhalation process of the electronic cigarette. During the inhalation process, when the aerosol with a higher temperature encounters the mounting bracket 5 with a lower temperature, condensate will be generated and attached to the mounting bracket 5. As the use time increases, the condensate attached to the inner wall of the mounting bracket 5 will flow in the direction of the heating core, and then fall onto the absorbent cotton 6 and be adsorbed, thereby preventing the condensate from dripping onto the heating core, and also preventing the user from inhaling the condensate, thereby ensuring the smoking taste of the electronic cigarette and improving the user's usage experience.

[0033] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
