Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to an electronic cigarette with a highly efficient sealing structure. Background Technology

[0002] An electronic cigarette is an electronic product that mimics the effects of a cigarette. It uses an atomizing component to vaporize a liquid containing nicotine for the user to inhale. Electronic cigarettes typically consist of a cartridge and a device. The cartridge contains a reservoir to store the nicotine, and the atomizing component, powered by a battery within the device, transforms the liquid nicotine in the cartridge into vapor, giving the user a sensation similar to smoking, allowing them to "exhale clouds of smoke."

[0003] Before using an e-cigarette, the cartridge needs to be installed on the device. The air intake of the e-cigarette is located on the device. Airflow enters the device through the air intake and then flows into the cartridge. Because there is no sealing structure between the cartridge and the device, air leakage is easy to occur, which cannot meet the user experience and is not conducive to improving the competitiveness of the product.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, this utility model discloses an electronic cigarette with a highly efficient sealing structure, including a cigarette rod 1 and a cartridge 2. The cigarette rod 1 includes a cigarette rod shell 11, a power supply control component, a cigarette rod inner support 12, and an elastic sealing element 13. The cigarette rod shell 11 is sleeved on the cigarette rod inner support 12, the power supply control component is installed on the cigarette rod inner support 12, and the elastic sealing element 13 is sleeved on the upper end of the cigarette rod inner support 12. A sealing wall 130 is provided on the upper end of the elastic sealing element 13, and the sealing wall 130 is inclined outward from bottom to top. The sealing wall 130 can cooperate with the lower end face of the cartridge 2 to improve the sealing between the cigarette rod 1 and the cartridge 2.

[0020] By setting the sealing wall 130, it can fit tightly with the lower end face of the cartridge 2, improving the sealing performance between the cigarette rod 1 and the cartridge 2. Furthermore, by tilting it outward, the sealing wall 130 can be easily deformed when squeezed by the lower end face of the cartridge 2, thereby better fitting the sealing wall 130 to the lower end face of the cartridge 2, meeting the user's needs and effectively improving the product's competitiveness.

[0021] The sealing wall 130 has a funnel-shaped cross-section. Due to its inclined design, it can easily deform when squeezed by the cartridge 2, based on its elastic properties, thereby improving the sealing between the cartridge 2 and the cigarette rod 1.

[0022] The upper periphery of the inner support 12 of the cigarette rod is provided with a sealing installation step 120 that cooperates with the elastic seal 13, and the elastic seal 13 is provided on the sealing installation step 120.

[0023] By setting the sealing installation step 120, the stability of the position of the elastic seal 13 can be improved.

[0024] The inner support 12 of the cigarette holder and the elastic seal 13 are integrally molded. This integral molding improves the positional stability between the inner support 12 and the elastic seal 13, and also increases the matching degree. When the inner support of the cartridge 2 is installed into the outer shell 11 of the cigarette holder, there will be no friction between the elastic seal 13 and the inner wall of the outer shell 11, which would cause the elastic seal 13 to curl and deform, thus affecting the sealing performance.

[0025] A sealing protrusion ring 131 is provided around the elastic seal 13. The sealing protrusion ring 131 can cooperate with the inner wall of the cigarette rod shell 11 to improve the sealing performance between the elastic seal 13 and the cigarette rod shell 11.

[0026] The cartridge 2 is provided with an atomizing airflow channel, the outer shell 11 of the cigarette rod is provided with an air inlet 110, and the outer periphery of the elastic seal 13 is provided with an airflow groove 132. The airflow groove 132 can cooperate with the inner wall of the outer shell 11 of the cigarette rod to form an airflow channel. An airflow hole 133 communicating with the atomizing airflow channel is provided in the airflow groove 132.

[0027] There are two air inlets 110 and two air outlets 133, which are symmetrically arranged on both sides of the air outlet groove 132.

[0028] The two air inlets 110 effectively improve the user's suction experience.

[0029] The inner support 12 of the cigarette rod is provided with an electrode connecting pin 14 and a lower connecting magnet 15, and the cigarette cartridge 2 is provided with a connecting electrode and an upper connecting magnet.

[0030] The electrical connection between the cigarette rod 1 and the cartridge 2 is achieved by the cooperation of the electrode connecting pin 14 and the connecting electrode. The stability of the connection between the cartridge 2 and the cigarette rod 1 is improved by the cooperation of the upper connecting magnet and the lower connecting magnet 15.

[0031] The power supply control component includes a power supply battery 16, a main control board 17, and a charging interface 18. The charging interface 18 and the power supply battery 16 are both electrically connected to the main control board 17.

[0032] As can be seen from the above, the beneficial effects of this utility model are: by adopting its structure, it can effectively solve the problem of poor sealing between the cartridge 2 and the e-cigarette 1 in the prior art. Through the setting of the sealing wall 130, it can be tightly fitted with the lower end face of the cartridge 2, improving the sealing between the e-cigarette 1 and the cartridge 2. Furthermore, by being set outwardly, the sealing wall 130 can be more easily deformed after being squeezed by the lower end face of the cartridge 2, thereby better fitting the sealing wall 130 to the lower end face of the cartridge 2, meeting the user's needs and effectively improving the product's competitiveness.

[0033] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
