Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette that is leak-proof in terms of gas and liquid. Background Technology

[0002] Currently, existing electronic cigarettes use a sealing element on the outer wall of the main frame to seal the bottom of the adapter cavity, preventing air and liquid leakage due to poor sealing at the bottom of the adapter cavity. This element abuts against the inner wall of the outer shell. During the assembly of the main frame into the outer shell, the sealing element is often displaced and deformed due to pressure and scraping from the inner wall of the outer shell. This creates gaps between the outer wall of the main frame and the inner wall of the outer shell that go unnoticed. Condensate produced by the atomizer's e-liquid can enter the main frame through these gaps in the adapter cavity, causing a short circuit in the power board. Furthermore, when smoking, the atomized airflow enters the adapter cavity through the ventilation channel and leaks out through these gaps, resulting in less airflow and vapor production. Utility Model Content

[0003] The purpose of this invention is to provide an electronic cigarette that prevents air and liquid leakage. By designing a fixed structure and a raised edge on the sealing element, it solves the problems in the prior art of electronic cigarettes where gaps are not detected after the sealing element shifts or deforms during the assembly of the main frame into the shell, allowing condensate to enter the main frame through the gaps and cause a short circuit in the power board, and where the atomized airflow leaks through the gaps during smoking, resulting in insufficient airflow and smoke volume.

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.

[0025] 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.

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.

[0026] In this utility model, the terms "upper", "lower", "side", "top", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing and understanding the technology of this utility model. They are not intended to limit the device or component to a specific orientation or to be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0027] like Figure 1-8 As shown, this utility model provides an electronic cigarette that prevents air and liquid leakage, including an atomizer 1, a housing 10, a main unit 11 disposed inside the housing 10, and a sealing member 2 sleeved on the main unit 11. An adapter cavity 1001 is formed inside the housing 10, and the atomizer 1 is disposed inside the adapter cavity 1001. The sealing member 2 is provided with a plurality of protrusions 201 that abut against the inner wall of the housing 10 for sealing the adapter cavity 1001. A fixing structure 1103 is provided between the main unit 11 and the sealing member 2, and the sealing member 2 is fixed to the main unit 11 by the fixing structure 1103. The main unit 11 is provided with a power supply assembly 1102 for supplying power to the atomizer 1, and a ventilation section 1101 that communicates with the adapter cavity 1001 for providing atomized airflow to the atomizer 1. It should be noted that by designing the fixing structure 1103 and the protruding edge 201 on the sealing element 2, the problem of existing electronic cigarettes being caused by the sealing element 2 shifting and deforming when the main unit 11 is installed in the outer shell 10 due to the pressure of the outer shell 10, resulting in the condensate produced by the atomizer 1 atomizing e-liquid entering the main unit 11 from the adapter cavity 1001, causing a short circuit in the power component 1102, and air leakage after the atomized airflow enters the adapter cavity 1001 from the ventilation section 1101.

[0028] In some embodiments, each protruding edge 201 surrounds the outer peripheral wall of the seal 2, and each protruding edge 201 is arranged sequentially from top to bottom on the outer peripheral wall of the seal 2, with a gap 203 between each protruding edge 201 and its adjacent protruding edge 201. The fact that each protruding edge 201 surrounds the outer peripheral wall of the seal 2 allows for a tighter seal between the outer wall of the seal 2 and the inner wall of the housing 10. When the main unit 11 is installed inside the housing 10, the gap 203 releases the pressure exerted on the protruding edge 201 and the seal 2 by the inner wall of the housing 10, preventing the protruding edge 201 and the seal 2 from failing to recover after being subjected to pressure.

[0029] In some embodiments, the seal 2 is made of silicone, rubber, or latex, and each protrusion 201 is integrally formed with the seal 2. In this embodiment, the seal 2 is preferably made of silicone, which is soft, easy to assemble, has a large deformation coefficient, and provides good sealing performance. The seal 2 and the protrusion 201 are integrally formed using liquid silicone in-mold injection molding.

The upper end of the ventilation channel 703 communicates with the adapter cavity 1001, and the lower end of the ventilation channel 703 communicates with the ventilation groove 702. The ventilation groove 702 and the ventilation channel 703 constitute a ventilation part 1101. An air inlet 1002 communicating with the air inlet 704 is provided on the outer wall of the outer shell 10. Among them, the sealing plate 6 is used to seal the ventilation groove 702 to prevent external airflow from entering the ventilation groove 702 through the air inlet 1002 and the air inlet 704 and causing air leakage. When smoking, the external airflow enters the ventilation groove 702 through the air inlet 1002 and the air inlet 704 in sequence, and then enters the adapter cavity 1001 through the ventilation channel 703.

The sealing element 2 has four insertion holes 202 on its outer peripheral wall. The sealing element 2 is sleeved on the upper end of the main frame 7 of the host 11. Each pin 701 corresponds to an insertion hole 202. Each pin 701 is inserted into the corresponding insertion hole 202. The sealing element 2 is fixed to the upper outer wall of the main frame 7 by each pin 701 inserted into the corresponding insertion hole 202, so as to prevent the main frame 7 of the host 11 from being squeezed by the inner wall of the outer shell 10 when it is inserted into the outer shell 10, which would cause displacement and deformation, thus resulting in liquid and air leakage.

[0040] The main frame 7 of the main unit 11 is inserted into the lower end of the outer shell 10. Each protrusion 201 abuts against the inner wall of the lower end of the outer shell 10 to seal the gap between the outer shell 10 and the sealing element 2.

The heating core 105 will heat the e-liquid to produce smoke. The smoke can be inhaled through the mist outlet 101 at the top of the mouth-to-lung atomizer 1. External airflow can enter the ventilation groove 702 through the air inlet 1002 and the air inlet 704, and then enter the adapter cavity 1001 through the ventilation channel 703. The airflow can then enter the mist channel 104 through the air guide channel 107, and then drive the smoke produced by the heating core 105 heating the e-liquid to enter the user's mouth through the mist outlet 101 and be inhaled.
