Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette leak prevention technology, and in particular to a dustproof and leak-proof electronic cigarette. Background Technology

[0002] Currently, e-cigarettes are gaining popularity due to their ease of use and smoking cessation functions. Existing e-cigarettes mainly consist of two parts: an atomizer and a base. The atomizer includes a mouthpiece and an e-liquid cup. To prevent e-liquid leakage, a mouthpiece plug is often inserted into the mouthpiece channel at the end of the atomizer during shipping. However, this design has the following problems: First, the mouthpiece plug primarily prevents dust from entering the mouthpiece channel, but it does not protect the overall hygiene of the mouthpiece, resulting in a limited function and poor user experience. Second, the seal between the mouthpiece plug and the mouthpiece is poor, easily leading to e-liquid leakage and affecting user safety. Third, the mouthpiece plug needs to be removed during atomizer use; after removal, due to its small size and lack of connection to the atomizer, it is easily lost and cannot be reused.

[0003] In view of the existing related technologies, the existing e-cigarettes have problems such as the mouthpiece plug having a single function, failing to protect the overall hygiene of the mouthpiece, poor sealing between the mouthpiece plug and the mouthpiece leading to e-liquid leakage, and the mouthpiece plug being easy to lose. No effective solution has yet been proposed. Utility Model Content

[0004] In view of this, it is necessary to provide a dustproof and leak-proof electronic cigarette and electronic cigarette, so as to at least solve the problems of existing electronic cigarettes having a single function of the mouthpiece plug, which cannot protect the overall hygiene of the mouthpiece, poor sealing between the mouthpiece plug and the mouthpiece, which leads to e-liquid leakage, and easy loss of the mouthpiece plug.

[0005] This utility model provides a dustproof and leak-proof electronic cigarette, including a mouthpiece cover, a mouthpiece, and an oil cup.

When the mouthpiece cap is closed on the top of the mouthpiece, the mouthpiece plug is embedded in the upper end of the mouthpiece channel. A first oil seal structure is formed between the inner sidewall of the mouthpiece cap and the outer peripheral sidewall of the mouthpiece, and a second oil seal structure is formed between the outer peripheral sidewall of the mouthpiece plug and the inner peripheral sidewall of the mouthpiece channel. The first oil seal structure and the second oil seal structure are used to prevent e-liquid from leaking from the mouthpiece channel.

[0006] In some embodiments, the connecting structure includes a T-shaped buckle at one end of the connecting rod and a T-shaped groove on one side of the outer peripheral sidewall of the oil cup; wherein the connecting rod is engaged with the T-shaped groove of the oil cup by the T-shaped buckle, so that the connecting rod is fixedly connected to the oil cup.

[0007] In some embodiments, the outer peripheral sidewall of the nozzle plug is provided with a sealing ring protruding outward; when the nozzle cap is closed and fixed to the top of the nozzle, the inner sidewall of the nozzle cap forms the first oil seal structure in close contact with the outer peripheral sidewall of the nozzle, and the sealing ring forms the second oil seal structure in close contact with the inner peripheral sidewall of the nozzle channel.

[0008] In some embodiments, a base is also included, and a snap-fit ​​structure is provided between the base and the oil cup. The snap-fit ​​structure includes an inverted platform on the outer peripheral sidewall of the oil cup and an inner snap groove on the inner sidewall of the base; wherein the oil cup is connected and fixed to the inner snap groove of the base through the inverted platform.

[0009] In some embodiments, the device further includes an atomizing device, a power supply device, and a control board. The oil cup contains an integrated container with an atomizing channel in the center that communicates with the mouthpiece channel. The atomizing device, the power supply device, and the control board are all housed within the hollow cavity of the base. The integrated container, the atomizing device, the power supply device, and the integrated container are electrically connected to each other. The integrated container stores e-liquid; the atomizing device atomizes the e-liquid in the integrated container and discharges it through the atomizing channel and the mouthpiece channel; the power supply device provides power to the atomizing device; and the control board controls the start and stop of the atomizing device.

[0010] In some embodiments, an oil inlet is provided on one side of the oil cup, and an oil plug is provided at the oil inlet. The oil inlet is connected to the integrated barrel, and the oil plug can be opened or sealed at the oil inlet.

[0011] In some embodiments, the bottom of the base is provided with a charging port, which is electrically connected to the control motherboard; the charging port is used to charge the power supply device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The embodiments of this application provide a dustproof and leak-proof electronic cigarette and electronic cigarette with a novel structure and reasonable design. By covering the mouthpiece cap on the mouthpiece, the mouthpiece plug seals the mouthpiece channel to prevent dust, while the mouthpiece cap covers the outer surface of the mouthpiece to protect the overall hygiene of the mouthpiece, achieving the purpose of double sealing protection. It has strong functionality. Moreover, the mouthpiece cap and mouthpiece plug are fixedly connected to the oil cup through a connecting rod to prevent the mouthpiece plug from being lost when the atomizer is used. It can be covered and used again next time, which enhances the user experience and the safety and hygiene environment of the atomizer. It is highly practical. Attached Figure Description
