[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0020] like Figures 1-4 As shown, an interchangeable single / dual-electrode cartridge structure includes a cigarette holder 1, an oil cup 2, and a metal casing 12 for the smoke duct. The oil cup 2 is mounted on the upper side of the cigarette holder 1, and a dust plug 3 is provided on the upper middle part of the oil cup 2. A fiberglass tube 4 is mounted on the lower side of the dust plug 3, and an oil-absorbing cotton 5 is provided on the outer side between the dust plug 3 and the fiberglass tube 4. A silicone plug 7 with air vents is mounted on the lower outer side of the finished core 9, and air vents are provided on both sides above the silicone plug 7. A cartridge bottom cover 8 is provided on the lower side of the silicone plug 7, and the center of symmetry of the silicone plug 7 is aligned with the center of symmetry of the cartridge bottom cover 8. The center coincides, and the inner sides of the bottom cover 8 of the e-cigarette cartridge are provided with oil-filling silicone plugs 10, and the position of the oil-filling silicone plugs 10 corresponds to the position of the air hole of the air hole silicone plug 7; there are two oil-filling silicone plugs 10 inside the oil cup 2. The single and dual e-cigarette cartridges are designed with a single set of finished cores 9 and electrode nails 11. The finished core 9 has oil seepage holes that penetrate its inner and outer walls. E-liquid flows into the inner cavity of the finished core 9 through the oil seepage holes. When the user smokes, the heating wire 14 is controlled to heat up, so that the e-liquid inside the finished core 9 is atomized into smoke at high temperature and then discharged.
[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a flue metal cover 12 is installed at the bottom of the oil cup 2, and an electrode nail 11 is fixed on the upper side of the inside of the flue metal cover 12. A lead wire hole 13 is opened on the bottom surface of the flue metal cover 12, and a lower sealing plug is filled inside the lead wire hole 13. The diameter of the lead wire hole 13 is 1.4±0.05mm. An upper silicone 6 is installed on the lower outer side of the fiberglass tube 4, and a finished core 9 is connected to the lower side of the fiberglass tube 4. The finished core 9 has an oil seepage hole that penetrates its inner and outer walls. The device is internally equipped with a heating wire 14, and the conductive pin of the heating wire 14 passes through the lower sealing plug and is electrically connected to the electrode pin 11. The conductive lead of the heating wire 14 is inserted through the pin hole 13 of the metal casing 12 of the flue. The lower sealing plug can enhance the sealing performance and form a negative electrode in contact with the metal casing of the tobacco cartridge. The tobacco stick 1 is equipped with spring pins on both sides to realize the interchangeability of single and dual tobacco cartridges. The integration of single and dual tobacco cartridges and the unified negative electrode design allow different tobacco cartridges to be used in the same tobacco stick 1, simplifying the usage.
[0022] In summary, as Figures 1-4As shown, the interchangeable single and dual-electrode cartridges have a structure where, during use, the inside of the oil cup 2 forms a sealed oil storage space. Two silicone oil-filling plugs 10 are used for oil filling. The conductive lead of the heating wire 14 passes through the pin hole 13 of the metal casing 12 of the smoke duct. The lower sealing plug enhances the sealing performance and forms a negative electrode in contact with the metal casing of the cartridge. The interchangeability of single and dual-electrode cartridges is achieved by setting spring pins on both sides of the smoke rod 1. The integration of single and dual-electrode cartridges, through a unified negative electrode design, allows different cartridges to be used in the same smoke rod 1. When smoking, the finished core 9 has an oil seepage hole that runs through its inner and outer walls. The e-liquid flows into the inner cavity of the finished core 9 through the oil seepage hole. Then, the heating wire 14 is controlled to heat up, so that the e-liquid inside the finished core 9 is atomized into smoke at high temperature and then discharged. At this time, the single-electrode and dual-electrode cartridges can be interchanged, which simplifies the use. By optimizing the conductive electrode nail 11 of the cartridge, the usage restrictions of single and dual-electrode cartridges are simplified, and production efficiency and product flexibility are improved. In this way, the use process of the interchangeable single and dual-electrode cartridge structure is completed.
