Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomization device that can be filled with oil, vented, and sealed. Background Technology

[0002] Currently, existing atomizing devices all have an oil hole on the main body that connects to the oil storage chamber, and then an oil plug is placed on the main body to seal the oil hole. When filling, the oil plug must be opened first, and then oil is poured into the oil storage chamber through the oil hole. After filling, the oil plug must be installed back in place to seal the oil hole. This method of filling is not only cumbersome, but the oil bottle will also block the oil hole during the filling process, preventing the air in the oil storage chamber from being expelled quickly. This causes the e-liquid to enter the oil storage chamber slowly, affecting the filling efficiency. In addition, the oil plug is exposed and can be easily opened by children and get contaminated with dust, which can cause the e-liquid in the storage chamber to leak out and be ingested by children. The dust can then enter the oil storage chamber and contaminate the e-liquid. Utility Model Content

It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0024] It should be noted that the specification of this utility model contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features of the utility model described above, the various technical features of the utility model in the following embodiments and examples, and the various technical features of the utility model in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, in one example, feature A+B+C is described, and in another example, feature A+B+D+E is described. Features C and D are equivalent technical means that serve the same function; technically, only one needs to be used, and they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0025] In this utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing and understanding the technology of this utility model, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1-5 As shown, this utility model provides an atomizing device that can be injected with oil, vented, and sealed. It includes an oil storage body 13, an oil storage chamber 703, and an exhaust channel 701 communicating with the oil storage chamber 703. It also includes an oil-injectable and oil-sealing structure 1301 disposed in the exhaust channel 701. The oil-injectable and oil-sealing structure 1301 has an oil injection part 305 that can inject oil into the oil storage chamber 703, a sealing member 5 that can seal the bottom end of the exhaust channel 701, and an elastic member 4 that can move the oil injection part 305 and the sealing member 5 to the oil storage chamber 703 when pressure is applied and can reset the oil injection part 305 and the sealing member 5 when pressure is released. It should be noted that by designing the oil-filling and sealing structure 1301, oil can be injected into the oil storage chamber 703 through the oil filling part 305 after pressure is applied, making the oil storage operation more convenient. At the same time as oil filling, air in the oil storage chamber 703 can be discharged through the exhaust channel 701, which can speed up the oil filling efficiency. After oil filling, the pressure is released and the bottom end of the exhaust channel 701 can be sealed by the sealing element 5. The oil filling part 305 can be moved into the exhaust channel 701 and isolated from the oil storage chamber 703, which can prevent the e-liquid in the oil storage chamber 703 from flowing out and dust from entering the oil storage chamber 703 and contaminating the e-liquid. Among them, the elastic element 4 is a spiral spring, and the sealing element 5 is made of silicone material.

[0027] In some embodiments, the e-liquid filling section 305 is formed by an e-liquid filling hole 304 and / or an e-liquid filling channel 303. In this embodiment, the e-liquid filling section 305 is formed by an e-liquid filling hole 304 and an e-liquid filling channel 303, wherein the e-liquid is used to pass through during e-liquid filling, and the e-liquid filling hole 304 is used to allow the e-liquid to enter the e-liquid storage chamber 703.

[0028] In some embodiments, the oil-fillable sealing structure 1301 includes a pressing member 3, the lower end of which is necked to form a telescopic member 301. An elastic member 4 is sleeved on the upper end of the telescopic member 301, and the top end of the elastic member 4 abuts against the bottom end of the pressing member 3. The top end of the pressing member 3 is flush with the top end of the venting channel 701. It should be noted that when oil is injected, pressing the pressing member 3 at the top end of the venting channel 701 can deform the elastic member 4, thereby causing the telescopic member 301 to move from the venting channel 701 into the oil storage cavity 703, and causing the oil injection part 305 and the sealing member 5 to move into the oil storage cavity 703.

[0029] In some embodiments, the oil-sealing structure 1301 further includes a limiting member 6. The limiting member 6 has a groove 601 at its top end. The lower end of the sealing member 5 is inserted into the groove 601, and the top end of the sealing member 5 abuts against the lower end of the exhaust channel 701. The lower end of the telescopic member 301 is inserted into the limiting member 6 and the sealing member 5. The groove 601 is used to accommodate the lower end of the sealing member 5. The top end of the sealing member 5 abuts against the bottom end of the exhaust channel 701 to seal the bottom end of the exhaust channel 701. The lower end of the telescopic member 301 is inserted into the limiting member 6 and the sealing member 5 to fix the limiting member 6 and the sealing member 5 at the lower end. The limiting member 6 is made of metal and is used to limit the position of the sealing member 5 at the lower end of the telescopic member 301, preventing the sealing member 5 from deforming or shifting under pressure after it abuts against the bottom end of the exhaust channel 701, thus preventing poor sealing performance.

[0030] In some embodiments, the exhaust channel 701 has a limiting step 704, and the bottom end of the elastic member 4 abuts against the limiting step 704; the top end of the pressing member 3 is provided with an oil injection groove 302, the oil injection groove 302 is conical, the bottom wall of the oil injection groove 302 is provided with an oil injection channel 303, the oil injection channel 303 extends into the telescopic member 301, the upper end of the telescopic member 301 is provided with a plurality of oil injection holes 304 communicating with the oil injection channel 303, and the oil injection channel 303 and the oil injection holes 304 constitute an oil injection part 305. The limiting step 704 provides support to the elastic element 4, preventing it from moving downwards. The oil filling groove 302 accommodates the oil filling tube of the e-liquid bottle. When filling, the oil filling tube is inserted into the oil filling groove 302 and the pressing member 3 is pressed down. The deformation of the elastic element 4 allows the telescopic member 301 to move from the exhaust channel 701 into the oil storage chamber 703. At the same time, the sealing member 5 and the oil filling hole 304 also move into the oil storage chamber 703, and the exhaust channel 701 can be opened. When the e-liquid bottle is squeezed, e-liquid can flow through the oil filling channel 303 and out of the oil filling hole. 304 enters the oil storage chamber 703. While filling the oil, the air in the oil storage chamber 703 can be discharged through the exhaust channel 701. After filling the oil, the e-liquid bottle is removed. At this time, under the elastic force of the elastic element 4, the telescopic element 301 will move upward. At this time, the oil filling hole 304 will move into the exhaust channel 701 and be isolated from the oil storage chamber 703. The sealing element 5 will move to abut against the bottom of the exhaust channel 701 to seal the exhaust channel 701, thereby preventing the e-liquid from flowing out of the oil storage chamber 703 and dust from entering the oil storage chamber 703 through the exhaust channel 701.
