[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0032] This invention provides an oil-coil separation and leak-proof structure for electronic cigarettes, such as... Figure 1 As shown, the oil-coil separation and leak-proof structure includes an oil cup assembly 100 and an atomizer base assembly 200. The oil cup assembly 100 and the atomizer base assembly 200 are kept separate when stored and assembled together when in use. The oil cup assembly 100 has an oil reservoir for storing e-liquid, and the atomizer base assembly 200 has an atomizing coil for atomizing e-liquid. When the atomizer base assembly 200 is assembled with the oil cup assembly 100, the atomizing coil on the atomizer base assembly 200 can be inserted into the oil reservoir so that the e-liquid in the oil reservoir can enter the atomizing coil to achieve normal use of the electronic cigarette.

[0033] This structure, which separates the atomizer core for storage and assembles it together for use, can prevent problems such as e-liquid deterioration and reduced flavor caused by prolonged immersion of the atomizer core in e-liquid.

[0034] Figures 2-3 The specific structure of the oil cup assembly 100 is given. The oil cup assembly 100 includes an oil cup shell 110 with a hollow inner cavity. The oil cup shell 110 has a downward-opening assembly port and an upward-facing suction port.

[0035] The hollow inner cavity of the oil cup shell 110 is provided with an upper sealing structure 120 and a lower sealing structure 150 at a certain distance apart from each other, the outer peripheral edges of the upper sealing structure 120 and the lower sealing structure 150 are sealed with the inner wall of the oil cup shell 110, and the center of the upper sealing structure 120 and the lower sealing structure 150 is provided with a hollow mounting hole, and a gas guide pipe 130 is arranged between the two mounting holes, the two ends of the gas guide pipe 130 are inserted into the two mounting holes respectively, and the part of the gas guide pipe 130 in the mounting hole is sealed with the inner wall of the mounting hole. In this way, the oil storage cavity 160 is formed between the upper sealing structure 120 and the lower sealing structure 150, and between the inner wall of the oil cup shell 110 and the outer wall of the gas guide pipe 130. As a preferred, the upper sealing structure 120 and the lower sealing structure 150 are both silica gel seats.

[0036] The oil storage cavity 160 is used to store tobacco tar. In order to inject tobacco tar into the oil storage cavity, the lower sealing structure 150 is provided with an oil injection hole, tobacco tar is injected into the oil storage cavity 160 through the oil injection hole, and after the oil storage cavity 160 is filled with tobacco tar, the oil injection hole of the lower sealing structure 150 is closed by a silica gel plug 151. Before the product is shipped, the oil storage cavity 160 has been filled with tobacco tar through the oil injection hole. Due to the upper and lower sealing structures, the tobacco tar in the oil storage cavity 160 will not leak.

[0037] When the oil cup assembly 100 and the atomizer assembly base 200 are assembled together, it is necessary to enable the tobacco tar to enter the atomizing core, so the sealed oil storage cavity needs to be unsealed to form communication with the atomizing core during assembly.

[0038] In order to achieve the above purpose, the gas guide pipe 130 is arranged to be pushed upward from the bottom by the atomizing core, after the gas guide pipe 130 moves upward relative to the oil storage cavity 160, the lower end of the gas guide pipe 130 is replaced by the atomizing core pushed in, at this time the atomizing core enters the inside of the oil storage cavity 160, so as to realize the communication between the oil storage cavity and the atomizing core.

[0039] As shown in Figures 4-5 The atomizer base assembly 200 includes a base 210 and an atomizing core arranged in the center of the base 210, the atomizing core includes a cylindrical heating wire support 230 and a heating wire 220 arranged in the inside of the heating wire support 230, the upper part of the cylindrical outer wall of the heating wire support 230 is provided with an oil inlet 233, when the atomizer base assembly 200 and the oil cup assembly 100 are assembled together, the heating wire support 230 pushes into the gas guide pipe 130 upward, so that the oil inlet 233 enters the oil storage cavity 160 with the upward movement of the heating wire support 230, so that the tobacco tar in the oil storage cavity 160 can enter the heating wire support 230 through the oil inlet 233 and be atomized into smoke after being heated by the heating wire 220.

[0040] In order to facilitate the upward pushing of the atomizing core into the air guide pipe 130, the air guide pipe 130 is divided into two sections, the lower section has a larger diameter than the upper section, so that a step is formed between the two sections, which serves as the force receiving surface for the upward pushing of the atomizing core. The top of the heating wire support 230 is provided with a sealing pushing part 231, which has an outer diameter slightly smaller than the inner diameter of the lower section of the air guide pipe 130, so that when assembled, the sealing pushing part 231 can be inserted into the lower section of the air guide pipe 130 and the top abuts against the step, thereby pushing the air guide pipe 130 upward.

[0041] In order to maintain the sealing, a plurality of sealing rings 232 are sleeved on the outer wall of the sealing pushing part 231.

[0042] Figures 6-8 The state diagram when the oil core separation oil leakage prevention structure is assembled is shown, when the user needs to use the electronic cigarette, as shown in Figure 6 The sealing pushing part 231 on the atomizer base assembly 200 is inserted into the opening of the lower section of the air guide pipe 130 of the oil cup assembly 100, at this time it is in a pre-assembled state; then as shown in Figure 7 The atomizer base 200 is pushed upward, the upper end surface of the sealing pushing part 231 abuts against the step at the variable diameter of the air guide pipe 130, and the air guide pipe 130 is moved upward, in this process the oil inlet 233 on the heating wire support 230 gradually enters the oil storage cavity 160; as shown in Figure 8 When the oil inlet 233 is completely inserted into the oil storage cavity 160, the base 210 and the assembly opening at the bottom of the oil cup shell 110 are assembled together by a clamping member. At this time, the oil cup assembly 100 and the atomizer base assembly 200 are assembled in place, at this time the oil inlet and the air passage are in an open state, and after the battery rod is assembled, the suction can be performed.

[0043] The above is only the preferred embodiment of the present application, which is only illustrative but not limiting. Those skilled in the art understand that many changes, modifications and even equivalents can be made within the spirit and scope of the invention defined in the claims, but all will fall within the protection scope of the present application.
