Description

Technical Field

[0001] This utility model relates to the technical field of electronic cigarettes, and in particular to an oil-core separated electronic cigarette structure. Background Technology

[0002] Electronic cigarettes are atomizers powered by rechargeable lithium polymer batteries. They heat e-liquid in a tank to produce vapor for users to inhale, and have a similar appearance, smoke, taste, and feel to cigarettes.

[0003] Currently, existing e-cigarettes use an integrated design for both the e-liquid and the atomizer core. As a result, the atomizer core and e-liquid are in constant contact. Under these conditions, the e-liquid is in a state of relative motion, which can easily lead to deterioration. Therefore, we have designed an e-cigarette structure that separates the e-liquid and the atomizer core, allowing the e-liquid to remain relatively still and clearly visible. This enables plug-and-play functionality and enhances the user experience. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an oil-core separation electronic cigarette structure.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An e-cigarette structure with a separate oil and core includes: a mouthpiece, an oil tank, and an atomizing core base; the mouthpiece is disposed on the top of the oil tank, and the atomizing core base is disposed at the bottom of the inner cavity of the oil tank; an inner ring is movably disposed in the center of the inner cavity of the oil tank, and an inner ring silicone is disposed in the inner cavity at the top of the inner ring, and inner ring air holes are evenly spaced around the bottom of the inner ring; the atomizing core base includes a base, and an atomizing core assembly is disposed in the center of the top of the base, and atomizing core air holes are evenly spaced around the center of the atomizing core assembly near the top, and the diameter of the top view of the atomizing core assembly matches the diameter of the top view of the inner ring.

[0007] In one embodiment, a top silicone is provided at the bottom of the inner cavity of the suction nozzle, and the central opening of the top silicone is perpendicular to the through hole in the center of the suction nozzle.

[0008] In one embodiment, the inner ring body is divided into two rings with different diameters, with the lower ring having a smaller diameter than the upper ring. The internal ring vent is located on the lower ring, and two silicone rings are provided at the connection between the lower and upper rings.

[0009] In one embodiment, an oil-absorbing cotton is provided in the central slot of the inner cavity of the atomizing core base, and the oil-absorbing cotton has through holes. The center of the atomizing core base is connected to the central column of the atomizing core assembly.

[0010] In one embodiment, the bottom of the oil tank is provided with a bottom silicone sealant, and an iron sheet is fitted onto the top of the bottom silicone sealant. Several protrusions are provided on the top of the side of the bottom silicone sealant near the inner cavity of the oil tank. The protrusions correspond to the circular holes opened on the iron sheet and are interference-fitted together.

[0011] In one embodiment, a groove is provided on one side of the inner ring, and a protrusion is provided on the column of the inner wall of the oil tank near the inner ring, which is engaged with the groove.

[0012] In one embodiment, both the iron sheet and the bottom silicone have a central hole, and the ring body at the bottom of the inner ring is inserted into the central hole.

[0013] In one embodiment, the number of air holes in the atomizing core is the same as the number of internal annular air holes, and their positions correspond one-to-one. The shape and size of the top view of the base are the same as the shape and size of the insertion port on the bottom top view of the atomizing core base.

[0014] In one embodiment, two electrodes and two magnets are disposed in the inner cavity at the bottom of the base, and the two electrodes and magnets are arranged in a left-right mirror image.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This utility model discloses an e-cigarette structure with a separate oil core. An internal ring is movable within the oil tank, containing an inner ring silicone pad, an inner ring air hole, and a silicone ring. These components, along with a bottom silicone pad and metal plate on the atomizer core base, restrict the internal ring's movement, limiting it to the center of the oil tank. Simultaneously, the atomizer core assembly on the base allows the internal ring to move upwards when the base is inserted. Furthermore, the design between the atomizer core air hole and the inner ring air hole ensures alignment, opening the oil path for immediate vaping. When not inserted into the base, the atomizer core and e-liquid do not come into contact, keeping the e-liquid in a static state and preventing deterioration. Attached Figure Description

[0024] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0025] like Figure 1-5 As shown, an electronic cigarette structure with a separate oil core includes: a mouthpiece 1, an oil tank 2, and an atomizing core base 3; the mouthpiece 1 is located at the top of the oil tank 2, and the atomizing core base 3 is located at the bottom of the inner cavity of the oil tank 2; an inner ring 21 is movably disposed in the center of the inner cavity of the oil tank 2, and an inner ring silicone 22 is disposed in the inner cavity at the top of the inner ring 21, and inner ring air holes 23 are evenly spaced around the bottom of the inner ring 21; the atomizing core base 3 includes a base 35, and an atomizing core assembly 31 is disposed in the center of the top of the base 35, and atomizing core air holes 36 are evenly spaced around the center of the atomizing core assembly 31 near the top, and the diameter of the top view of the atomizing core assembly 31 matches the diameter of the top view of the inner ring 21. It should be noted that the mouthpiece 1 and the top silicone 11 are connected to each other by a threaded structure at their respective center points, and the shape of the top view of the oil tank 2 is triangular;

[0026] When in use, the user needs to insert the base 35 into the atomizer core base 3, so that the atomizer core assembly 31 can be inserted into the inner cavity of the inner ring 21. At the same time, the central column at the top of the atomizer core assembly 31 will press against the silicone ring 24 in the inner ring 21, so that the inner ring 21 moves upward. Each inner ring air hole 23 will be aligned with each atomizer core air hole 36, thus connecting them. After the inner ring is lifted, it will enter the oil tank 2 from the bottom silicone 33, so that the e-liquid can enter the atomizer core air hole 36 from the inner ring air hole 23. At this time, you can inhale the mouthpiece 1 to atomize the e-liquid.

[0027] like Figure 1-5 As shown in one embodiment, a top silicone rubber 11 is provided at the bottom of the inner cavity of the suction nozzle 1. The top silicone rubber 11 has a central opening, which is perpendicular to the through hole in the center of the suction nozzle 1. It should be noted that the side of the top silicone rubber 11 near the top of the oil tank 2 is joined together by an interference fit between a guide post and a guide post hole.

[0028] like Figure 1-5 As shown in one embodiment, the inner ring 21 is divided into two rings with different diameters, with the lower ring having a smaller diameter than the upper ring. An internal vent 23 is located on the lower ring, and two silicone rings 24 are provided at the connection between the lower and upper rings. It should be noted that the upper ring is longer than the lower ring, and there is a certain amount of space between the internal vent 23 and the top silicone ring 11.

[0029] like Figure 1-5 As shown in one embodiment, an oil-absorbing cotton 32 is disposed in the central slot of the inner cavity of the atomizing core base 3. The oil-absorbing cotton 32 has through holes, and the center of the atomizing core base 3 is connected to the central column of the atomizing core assembly 31. It should be noted that a circular hole is provided in the center of the bottom of the base 35, and this hole is interconnected with the circular hole on the oil-absorbing cotton 32.

[0030] like Figure 1-5 As shown in one embodiment, the bottom of the oil tank 2 is provided with a bottom silicone rubber 33, and the top of the bottom silicone rubber 33 is fitted with an iron plate 34. Several protrusions are provided on the top of the side of the bottom silicone rubber 33 closest to the inner cavity of the oil tank 2. These protrusions correspond to the circular holes on the iron plate 34 and are press-fitted together. Both the iron plate 34 and the bottom silicone rubber 33 have a central circular hole, and the ring body at the bottom of the inner ring 21 is inserted into this circular hole. It should be noted that when the base 35 is not inserted into the atomizer coil base 3, the inner ring 21 will move into the bottom silicone rubber 33 under natural gravity, blocking the internal ring air holes 23 around the inner ring 21, thus preventing oil from entering the inner ring 21, and keeping the e-liquid in a relatively static state.

[0031] like Figure 1-5As shown in one embodiment, a groove is provided on one side of the inner ring 21, and a protrusion is provided on the column of the inner wall of the oil tank 2 near the inner ring 21. The protrusion and the groove are engaged with each other. It should be noted that this design can restrict the movement of the inner ring 21, so that it can only move up and down in the center of the oil tank 2.

[0032] like Figure 1-5 As shown, in one embodiment, the number of atomizer core air holes 36 is the same as the number of internal ring air holes 23, and their positions correspond one-to-one. The shape and size of the top view of the base 35 are the same as the shape and size of the insertion port on the bottom top view of the atomizer core base 3. It should be noted that this design allows the atomizer core air holes 36 and the internal ring air holes 23 to communicate with each other when the atomizer core assembly 31 is inserted into the internal ring 21.

[0033] like Figure 1-5 As shown, in one embodiment, two electrodes 37 and two magnets 38 are disposed in the inner cavity at the bottom of the base 35, with the two electrodes 37 and the magnets 38 arranged in a left-right mirror image. It should be noted that this design can power the heater in the atomizing core assembly 31.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
