Description

a smoke oil bottle

【Technical field】

The invention relates to a device for containing smoke oil, in particular to a smoke oil bottle with good sealing performance, suitable for various structures, simple production process, improved production efficiency, no safety hazard and simple structure.

【Background technique】

Based on the volatility of e-liquid, the storage and transportation of e-liquid has always been an important issue that manufacturers of e-liquid and e-cigarettes need to consider. The e-liquid bottle with good sealing performance, easy to use, and simple structure has always been the main choice of e-liquid. The pursuit of manufacturers and e-cigarette manufacturers and smokers.

Commonly used e-liquid bottles include two parts, one part is the bottle body and the other is the bottle cap. The bottle body and the bottle cap are fixed by screwing or plugging. Due to technical limitations, the caliber cannot be made too small, but the diameter of e-cigarettes is generally around 0.8mm. Therefore, e-liquid bottles that are screwed with threads usually cannot be directly injected into e-cigarettes. When injecting e-liquid, other injection tools are needed to assist, which is very inconvenient to use. There is an important problem with the e-liquid bottle with a direct plug-in structure. The cap of the e-liquid bottle is very easy to fall off, and the e-liquid bottle is easy to leak. For smokers, the e-liquid needs to be carried with them, and the environment where it is placed is also It is not fixed, and there is no strict clamping structure. If the e-juice bottle is turned upside down or slightly squeezed, the e-juice oil will easily leak out. Therefore, the structure of the e-liquid bottle with a plug-in structure cannot be adopted of course.

At present, there are also e-liquid bottles that include three parts, one is the bottle body, the other is the bottle mouth, and the third is the bottle cap. The bottle body and the bottle cap are fixed by screwing or plugging. The same problem exists in the two-part e-liquid bottle, so this connection method between the bottle cap and the bottle mouth cannot be adopted. The bottle body and the bottle mouth adopt a threaded screw connection structure or a structure made by integrally forming the bottle body and the bottle mouth. When the threaded connection structure is used between the bottle body and the bottle mouth, the connecting part between the bottle body and the bottle mouth can only adopt a single circular structure. The connection structure will be subject to many restrictions; in addition, the threaded connection structure is easy to age during long-term use, resulting in the outflow of e-liquid, which is of course what we do not want to see. In the process of producing and assembling the e-juice bottle with the structure, a large amount of labor is consumed, which greatly reduces the production efficiency. In addition, if the manufacturer adopts the method of integrally forming the bottle body and the bottle mouth to make the e-liquid bottle, the processing technology of the e-liquid bottle is subject to many restrictions, especially when making the e-liquid bottle with a small capacity. Many processes cannot meet the designer's requirements, or the processing technology is very complicated and the production cost is too high. Designing a new matching bottle body and bottle mouth structure has always been the expectation of manufacturers.

Whether it is a plug-in connection or a screw-on e-liquid bottle, there is a problem: the opening method is very simple, even children can easily open the e-liquid bottle, and smokers usually keep the e-liquid at home. Therefore, it is easy for children to get the e-juice bottle. Today, when accidental ingestion incidents occur frequently, we should be aware that there are certain safety hazards in the e-juice bottle with this structure. Therefore, both e-liquid manufacturers and smokers hope to design new e-liquid bottles that can overcome the above-mentioned shortcomings.

Defined by the card slot and the hook provided on the mouth of the bottle, there are three clamping structures between the upper cover and the lower cover, two of which are a pair of clamping strips and bayonets that cooperate with each other, and the other A clamping structure is an arc-shaped strip and an arc-shaped groove that cooperate with each other, and a bottle mouth is arranged on the lower cover, and the e-liquid in the bottle flows out through the bottle mouth, and the diameter of the bottle mouth is 0.2mm-1.5mm.

Compared with the prior art, the e-liquid bottle of the present invention is designed in three sections, and any shape of the e-liquid bottle can be realized by using the structure described in the present invention and the modified embodiment of the present invention. Since the e-liquid bottle is made separately, its Not only can the model structure of the e-liquid bottle be simplified, but also the process of making the e-liquid bottle can be simplified. Further, manufacturers can standardize the parameters of the upper end of the bottle body and the lower end of the lower cover of the e-liquid bottle, and the bottles of different shapes produced by using the standardized parameters can be engaged with different shapes of the lower cover, which enhances the The commonality between the cap and the bottle body simplifies the production process of various types of e-liquid bottles. In industrial production, we first put the e-liquid into the bottle, then gently press the lower cover, the seal between the bottle body and the lower cover is snapped, and then the upper cover is fastened, the operation is simple and fast, The smooth assembling time of the existing vape juice bottle is about 8 seconds, while the assembling time of the vape juice bottle disclosed by the present invention is about 2 seconds, which greatly shortens the time spent in assembling the vape juice bottle. The structure of the upper end of the bottle body and the lower end of the lower cover match each other, especially the combination of the liquid blocking strip and the liquid blocking ring, which can make the e-liquid bottle achieve a very good sealing effect. The hook structures cooperate with each other to form the first clamping structure between the bottle body and the lower cover. After the locking groove and the hook are engaged and engaged, the hook is fixed on the arc between the liquid blocking ring and the locking piece in the vertical direction. In the horizontal direction, it is clamped by two locking pieces between the shaped protrusions, so the bottle body is firmly clamped on the lower cover, and the bottle body and the lower cover are tightly clamped. The structure of the bottle is equipped with a frustum structure, which increases the capacity of the e-liquid bottle. Taking the 30ml e-liquid bottle as an example, the capacity of the e-liquid bottle is 5%-30% larger than that of the e-liquid bottle of the same volume. % capacity. The bottom of the truncated cone also includes a groove, which is used to clamp the bottom of the lower cover to form a second clamping structure between the bottle body and the lower cover. Thus, a double clip connection is formed between the bottle body and the lower cover from inside to outside, and the fixed connection between the bottle body and the lower cover is stable. The structure between the upper cover and the lower cover is matched, and the matching snap-in structure between the upper cover and the lower cover is arranged on the sides perpendicular or parallel to each other of the upper cover and the lower cover. The arc-shaped strips and arc-shaped grooves are located on the three sides of the upper cover and the lower cover, which make the clamping between the upper cover and the lower cover stable. In addition, a matching bottle mouth is also set in the center of the upper cover and the lower cover. and the bottle mouth groove, thus, a full range of clamping and bonding is realized between the upper cover and the lower cover. To open the upper cover, there must be three forces acting on the upper cover at the same time, and the three forces are located on two planes perpendicular to each other. Specifically, two of the opposite forces parallel to each other correspond to the clamping strips, and the force direction is toward the upper cover. Inside, the direction of another force is tangential to the side of the upper cover and acts on the concave curved surface between the upper cover and the lower cover, and the direction of the force is upward of the upper cover. The extrusion of the object causes the lower cover to fall off, which avoids the problem that the upper cover of the existing e-liquid bottle is easy to fall off and causes the e-liquid to flow out, and also prevents children from easily opening the e-liquid bottle, thereby pouring out the e-liquid or even eating it by mistake. The e-liquid bottle of the present invention adopts a square structure, which is convenient to carry and has high space utilization rate. The outside of the e-liquid bottle adopts a rounded or chamfered structure, so that the e-liquid bottle has a beautiful appearance and a comfortable hand feel. There is also a fingerprint slot on one side, and the inner wall of the fingerprint slot is matched with a snap-fit structure. The fingerprint slot adopts an ergonomic design, which is convenient for opening the e-liquid bottle, and its operation is comfortable and convenient. To sum up, the e-liquid bottle disclosed by the present invention not only has good sealing performance and is suitable for e-liquid bottles of various structures, but also has the advantages of simple production process, high production efficiency, and no potential safety hazard.
