Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and particularly to an oil inlet structure of an open oil electronic cigarette. Background Art

[0002] Generally, an open oil electronic cigarette forms a storage space for e-liquid through an oil cup and an atomizing tube inside the oil cup; the e-liquid enters the cotton for storing oil in the atomizing tube through an oil inlet hole on the atomizing tube to supply oil to the atomizing core; and then is atomized by the atomizing core to form smoke for the smoker to inhale. Since the atomizing core is placed in the axial smoke channel formed by the cotton for storing oil, and the smoke channel communicates with the outside through a mouthpiece; a channel communicating the atomizing core with the outside is thus formed. Therefore, the existing open oil electronic cigarettes are prone to oil leakage problems. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide an oil inlet structure for an open oil electronic cigarette; through the improved oil inlet structure, it is ensured that the electronic cigarette will not leak oil no matter how it is placed when not in use.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0005] The oil inlet structure includes an oil cup, an atomizing tube, and a silicone rubber under the oil cup; a mouthpiece is formed at the top of the oil cup, and an atomizing tube is connected to the mouthpiece inside the oil cup; the silicone rubber under the oil cup is arranged at the bottom of the oil cup; the lower end of the atomizing tube is inserted into the silicone rubber under the oil cup; a spiral groove is arranged on the outer surface of the lower end of the atomizing tube inserted into the silicone rubber under the oil cup; an open oil inlet is arranged at the top of the spiral groove in the axial direction, and an oil inlet hole is arranged at the bottom in the axial direction.

[0006] The top of the spiral groove is a circular ring part; an open oil inlet is arranged on the circular ring part; starting from the open oil inlet, a spiral groove part is formed below the circular ring part; the end of the spiral groove part forms an open oil outlet; a circular ring groove part is arranged below the spiral groove part; the circular ring groove part communicates with the open oil outlet, and an oil inlet hole is arranged at the bottom of the groove.

[0007] The length of the spiral groove part is half a circle around the outer circle of the atomizing tube.

[0008] An oil inlet hole is arranged at the bottom of the circular ring groove part corresponding to the open oil outlet; oil inlet holes are also arranged at the bottoms of the circular ring groove parts that are symmetrically arranged in the circumferential direction.

[0009] The oil inlet hole is composed of three small holes arranged side by side.

[0010] The oil inlet structure of the present invention can ensure that after a part of the e-liquid is sucked, no matter what posture the electronic cigarette is placed flat; either the oil inlet hole is higher than the plane of the oil to form a partition and no oil enters, or the open oil outlet is higher than the plane of the oil to form a partition and no oil enters; protecting the electronic cigarette from leaking oil when placed flat. And the oil inlet channel formed by the spiral groove can also adjust the oil pressure of the oil inlet hole; reducing the occurrence of oil leakage problems. Brief Description of the Drawings

[0016] Figure 5 is the schematic diagram of the flat state of the electronic cigarette of the present invention. Detailed implementation manners

[0017] As Figures 1-5 shown, the oil inlet structure of the electronic cigarette of the present invention includes an oil cup 1, an atomizing tube 2, and a silicone rubber under the oil cup 3. A mouthpiece 11 is formed at the top of the oil cup 1, and the atomizing tube 2 is connected corresponding to the mouthpiece 11 inside the oil cup 1; the silicone rubber under the oil cup 3 is arranged at the bottom of the oil cup 1.

[0018] The lower end of the atomizing tube 2 is inserted into the silicone rubber under the oil cup 3; a spiral groove is arranged on the outer surface of the lower end of the atomizing tube 2 inserted into the silicone rubber under the oil cup 3.

[0019] Specifically, the top of the spiral groove is a circular ring portion 21; an oil showing inlet 22 is arranged on the circular ring portion 21; starting from the oil showing inlet 22, a spiral groove portion 23 is formed below the circular ring portion 21; the end of the spiral groove portion 23 forms an oil showing outlet 24; a circular ring groove portion 25 is arranged below the spiral groove portion 23; the circular ring groove portion 25 communicates with the oil showing outlet 24, and an oil inlet hole 26 is arranged at the bottom of the groove.

[0020] The length of the spiral groove portion 23 is half a circle around the outer circle of the atomizing tube. An oil inlet hole 26 is arranged at the bottom of the circular ring groove portion 25 corresponding to the oil showing outlet 24; meanwhile, oil inlet holes 26 are also arranged at the bottom of the circular ring groove portion 25 symmetrically around the circumference. The oil inlet hole 26 is composed of three small holes arranged side by side.

[0021] See Figure 1 shown, the silicone rubber under the oil cup 3 is in close fit with the outer surface of the atomizing tube 2 below the circular ring portion 21, the spiral groove portion 23, and the circular ring groove portion 25. The e-liquid above the circular ring portion 21 can only flow into from the circular ring portion 21, and then flow out from the oil showing outlet 24 along the spiral groove portion 23; then, it flows to the circular ring groove portion 25 and then to the oil inlet hole 26; and flows into the atomizing tube 2 through the oil inlet hole 26.

[0022] See Figure 5As shown, the cross-section of the electronic cigarette is generally flat. Rotate the atomizing tube 2 so that the oil inlet hole 26 faces the relatively wider two sides of the electronic cigarette. After a part of the e-liquid is sucked (for example, one-fourth or more), when the electronic cigarette is placed flat (including two directions), the e-liquid cannot enter the inside of the atomizing tube. When it is placed flat with the right desktop A as the support, the oil inlet hole is higher than the plane of the e-liquid, forming a partition and preventing the e-liquid from entering. When it is placed flat with the left desktop B as the support, the visible oil outlet 24 is higher than the plane of the e-liquid, forming a partition and preventing the e-liquid from entering. This protects against leakage when placed flat.

[0023] The remaining structures of the electronic cigarette not described in detail above are not related to the technical solution of the present invention, and those skilled in the art can understand them in detail through the drawings; they will not be elaborated here.

[0024] The above embodiments are descriptions of the specific implementation manners of the present invention, not limitations on the present invention; all equivalent transformations obtained according to the above descriptions should be within the protection scope of the present invention.
