[0026] In the figures: 10: Cap, 11: Inner cap, 111: Rubber ring, 20: Leak-proof component, 30: Oil guiding component, 31: Clamping head, 32: First end, 40: Body of the bottle, 41: Oil outlet hole, 42: Groove, 43: Clamping structure.
[0027] The following description illustrates the preferred embodiments of the invention using the accompanying figures. It should be understood that these examples are provided for explanation and clarification of the invention and are not intended to limit the invention.
[0028] The applicant's research has revealed that traditional e-liquid bottles have several significant shortcomings. First, manually dripping e-liquid increases the likelihood of user errors, which may lead to leakage, wastage, and damage to the e-cigarette device. Additionally, this process is cumbersome and negatively affects the user experience. Furthermore, some e-liquid bottles are poorly sealed, increasing the risk of leakage or contamination, which can affect the health and safety of users.
[0029] As shown in Figures 1-5, the invention provides a bottle mouth structure and an e-liquid bottle that includes an oil guiding component (30) and a leak-proof component (20). The oil guiding component (30) is equipped with an oil guide tube and a protruding part. The oil guide tube includes a first end (32) and a second end, with the second end connected to the body (40) of the bottle. The protruding part of the oil guiding component (30) is also connected to the body (40) of the bottle. The leak-proof component (20) is sleeved onto the first end (32) of the oil guide tube. The oil guide tube facilitates the flow of e-liquid through its connection to the body (40) of the bottle.
[0030] As shown in Figure 3, the oil guide tube is designed with a specialized interface for e-cigarette devices. The first end of the oil guide tube (32) is designed to match the heating element of the e-cigarette device, allowing for direct connection and delivery of e-liquid into the device without the need for manual refilling. During use, users can easily unscrew the cap (10) to open the e-liquid bottle. Align the bottle mouth with the e-cigarette device's interface and insert it securely. Pressing the bottle lightly causes the e-liquid to flow from the bottle into the device. This e-liquid bottle is suitable for use with both open-system e-cigarettes and disposable e-cigarettes.
[0031] The leak-proof component (20) has a circular cross-section. The bottom and bottom edges are also circular, matching the opening of the oil guide tube. This design ensures a tight fit between the leak-proof component (20) and the oil guide tube, improving sealing performance. When the leak-proof component (20) is connected to the oil guide tube, the circular cross-section ensures uniform contact on the sealing surface, reducing the risk of leakage from the bottom and effectively preventing e-liquid leakage.
[0032] The top surface of the leak-proof component (20) is equipped with several serrated membranes. These can also be describes as a plurality of slits in the top surface of the leak-proof component (20). These serrated membranes are evenly distributed around the centre of the cross-section, with the serrated tips pointing towards the centre. In its normal state, the serrated membranes remain closed. At this point, the leak-proof component (20) forms a fully sealed state, preventing e-liquid leakage. When external force is applied to the leak-proof component (20), such as when the e-cigarette's refill port is inserted into the oil guide tube, the serrated membranes automatically open to form a passage, allowing e-liquid to flow smoothly into the e-cigarette.
[0033] This design reduces the likelihood of leakage when liquid flow is not required. The leak-proof component (20) effectively prevents e-liquid leakage in non-use situations, while quickly opening the passage when needed, making it easier for users to replace the e-liquid bottle or perform other operations. This improves the overall user experience.
[0034] The bottle mouth structure is connected to a cap (10), and the cap (10) is connected to the oil guide tube. The cap (10) consists of an outer cap and an inner cap (11). The inner cap (11) is housed inside the outer cap, providing an additional protective layer that effectively prevents dust, foreign objects, or contaminants from entering the bottle mouth, ensuring the purity of the e-liquid.
[0035] The inner side wall of the inner cap (11) is threaded. The threaded structure of the inner cap (11) provides a better sealing effect. When the inner cap (11) is tightly screwed, the threads ensure that the inner cap (11) is securely sealed within the outer cap, effectively preventing e-liquid leakage or contamination from external sources.
[0036] The outer side wall of the oil guide tube is also threaded, and the oil guide tube is threadedly connected to the inner cap (11) of the cap (10). The threaded connection ensures that the oil guide tube and the cap (10)'s inner cap (11) are securely connected, preventing accidental loosening. When users refill the e-liquid, the threaded connection between the oil guide tube and the cap (10) ensures easy tightening and loosening, improving the user experience.
[0037] This design improves the overall sealing performance of the cap (10) and oil guide tube, effectively preventing e-liquid leakage while improving the convenience and safety of the user's experience. The combination of the inner and outer caps, the threaded design, and the threaded connection all contribute to improving the product's overall reliability and user-friendliness.
[0038] The inner cap (11) is fitted with a rubber ring (111), whose inner diameter is larger than that of the leak-proof component (20). The design of the rubber ring (111) further enhances the sealing performance of the cap (10). When the inner cap (11) is screwed tight, the rubber ring (111) compresses, forming a tighter seal that effectively prevents e-liquid leakage. The rubber material has good elasticity and sealing performance. Because of its flexibility, the rubber ring (111) can better adapt to the shape of the leak-proof component (20), filling potential gaps and ensuring complete sealing of the bottle mouth during use. This prevents e-liquid leakage or external contamination, ensuring that users have a better experience when using the e-liquid.
[0039] An e-liquid bottle, wherein the e-liquid bottle includes a body (40), and the body (40) is connected to the bottle mouth structure.
[0041] The oil outlet hole (41) is connected to the second end of the oil guide tube, and the groove (42) is nested with the protruding part of the oil guiding component (30).
[0043] The clamping structure (43) is a recessed part on the inner wall of the body (40) that matches the shape and size of the clamping head (31). The clamping structure (43) includes a plane perpendicular to the inner wall of the body (40) and an inclined surface. The plane and the inclined surface intersect at an acute angle, with the opening facing downwards.
[0044] The outer side wall of the protruding part of the oil guiding component (30) is provided with a clamping head (31), and the clamping head (31) engages with the clamping structure (43). The clamping head (31) and the clamping structure (43) provide a secure connection, ensuring that the protruding part of the oil guiding component (30) is securely attached to the clamping structure (43) of the body (40). The user only needs to insert the clamping head (31) of the oil guiding component (30) into the clamping structure (43) of the body (40) to complete the assembly, improving the product's ease of use.
[0045] At the same time, due to the design of the clamping structure (43), the oil guiding component (30) can be easily inserted into the body (40) but is not easily removed, preventing the oil guiding component (30) from falling off.
[0046] The leak-proof component (20) is made of silicone. The use of silicone for the leak-proof component (20) increases its sealing performance, ensuring that the bottle mouth remains sealed during use, effectively preventing e-liquid leakage. The silicone material is softer, making it easier to use and reducing the likelihood of wear or damage that may occur with harder materials.
[0047] Additionally, the body (40) is made from transparent, eco-friendly material, allowing users to observe the remaining e-liquid and clearly display the colour and quality of the e-liquid. The pull-and-plug design, combined with optimized material selection, balances user convenience and environmental protection, addressing some of the issues faced with traditional bottles during the refilling process, while providing users with a more convenient, safe, and eco-friendly e-liquid experience.
[0048] The working principle of the bottle mouth structure and e-liquid bottle described in this invention is as follows:
The bottle mouth structure and e-liquid bottle include an oil guiding component and a leak-proof component. The oil guiding component is provided with an oil guide tube and a protruding part. The oil guide tube includes a first end and a second end, with the second end connected to the body of the e-liquid bottle. The protruding part of the oil guiding component is connected to the body of the e-liquid bottle. The leak-proof component is sleeved onto the first end of the oil guide tube. The bottle mouth structure is connected to a cap, and the cap is connected to the oil guide tube.
[0049] The inner cap of the bottle cap is threaded. The user can simply unscrew the outer cap to open the bottle cap. The user inserts the necessary part of the e-cigarette device into the bottle cap, and the oil guide tube connects with the oil outlet hole of the bottle. The protruding part of the oil guiding component engages with the clamping structure of the bottle body, ensuring that the oil guide tube is securely connected to the bottle cap. The leak-proof component, made of silicone, is soft and provides effective sealing. When needed, it opens a passage to ensure that the e-liquid flows smoothly into the e-cigarette device. The e-liquid bottle can be used for both open-system and disposable e-cigarettes. When the user needs to refill e-liquid while using the e-cigarette, they simply insert or remove the bottle without manual refilling, which is quick and convenient. This design eliminates the complexity, operational risks, and issues associated with traditional manual refilling methods.
