Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette with an oil-core separation structure. Background Technology

[0002] Electronic cigarettes work by atomizing e-liquid into vapor using an atomizer core, which is then powered by the device. If e-liquid isn't supplied to the atomizer core promptly while the device is powered, it can easily become damaged due to dry burning. Similarly, if the atomizer core isn't used for an extended period after being supplied with e-liquid, leakage can also occur. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an electronic cigarette with an oil-core separation structure, which can avoid problems such as dry burning and oil leakage.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes an oil cup, an atomizing tube, an oil reservoir, and an atomizing core. A mouthpiece is formed at the top of the oil cup, and the atomizing tube is connected below the mouthpiece inside the oil cup. The atomizing tube contains an oil reservoir. The oil reservoir is hollow and houses the atomizing core. An oil inlet is located at the lower end of the atomizing tube. The cigarette also includes an oil cup support, a lower support, and an airway support. The bottom end of the atomizing tube is connected to the airway support via the lower support. The oil cup support is sealed at the bottom of the oil cup. The lower support and the bottom ends of the atomizing tube pass through the oil cup support. The airway support allows the atomizing tube to move axially. When the atomizing tube is moved to the top of its stroke, the oil inlet is open above the oil cup support; when the atomizing tube is moved to the bottom of its stroke, the oil inlet is closed inside the oil cup support.

[0006] It also includes a cartridge bottom cover; the cartridge bottom cover is connected to the bottom of the oil cup; when the airway support moves the atomizing tube to the bottom of the stroke, the bottom end of the airway support is exposed at the bottom of the cartridge bottom cover.

[0007] It also includes a cigarette rod assembly; the cigarette rod assembly is assembled with the oil cup and the bottom cover of the cartridge in a left-right manner; a mating part protrudes from the bottom of the cigarette rod assembly corresponding to the bottom cover of the cartridge; when the mating part is exposed at the bottom end of the airway support and is in a state of structural interference with the airway support, the cigarette rod assembly cannot be mated with the bottom cover of the cartridge.

[0008] The oil cup support is in the shape of an inverted cup; the upper part of the lower support and the airway support are located inside the oil cup support; the airway support drives the lower support to move axially within the oil cup support, and simultaneously drives the bottom end of the atomizing tube to be located inside the oil cup support or exposed outside the oil cup support.

[0009] This invention uses an airflow support to drive the atomizing tube axially; thus, the oil cup support sealed at the bottom of the oil cup allows the oil inlet of the atomizing tube to be open or closed. Simultaneously, when the airflow support moves the atomizing tube downwards and the oil inlet is closed, the e-cigarette cannot be assembled with the oil cup and cartridge bottom cover, and power cannot be supplied to the atomizing core; thus ensuring that dry burning does not occur. The airflow support controls the opening and closing of the oil inlet, and can also close the oil inlet when not in use; preventing oil leakage from the atomizing channel.

[0014] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0015] like Figures 1 to 3 As shown, the electronic cigarette of this utility model includes a cartridge assembly and a cigarette rod assembly 02. The cartridge assembly includes an oil cup 1, an atomizing tube 2, an oil storage cotton 3, an atomizing core 4, an oil cup support 5, a lower support 6, an airway support 7, and a cartridge bottom cover 8.

[0016] The top of the oil cup 1 forms a mouthpiece 11, and the bottom is connected to the cartridge bottom cover 8. The mouthpiece 11 inside the oil cup 1 is connected to the atomizing tube 2 below, and the atomizing tube 2 is equipped with an oil storage cotton 3; the oil storage cotton 3 is hollow and has an atomizing core 4; the lower end of the atomizing tube 2 is provided with an oil inlet 21.

[0017] The bottom end of the atomizing tube 2 is connected to the airway support 7 via the lower bracket 6.

[0018] The oil cup support 5 is sealed at the bottom of the oil cup 1. The oil cup support 5 is in the shape of an inverted cup; the upper parts of the lower support 6 and the airway support 7 are located inside the oil cup support 5; the bottom end of the atomizing tube 2 passes through the oil cup support 5. The airway support 7 can drive the atomizing tube 2 to move axially; when the atomizing tube 2 is moved to the top of its stroke, the oil inlet 21 is located above the oil cup support 5 and is in the open state. When the atomizing tube 2 is moved to the bottom of its stroke, the oil inlet 21 is located inside the oil cup support 5, and the position of the oil inlet 21 corresponds to the position of the oil cup support 5 forming the bottom of the oil cup support 5, and is in the closed state; at this time, the bottom end of the airway support 7 is exposed at the bottom of the cartridge bottom cover 8.

[0019] The cigarette rod assembly 02 is assembled with the oil cup 1 and the cartridge bottom cover 8 in a left-right manner; a mating part 021 protrudes from the bottom of the cigarette rod assembly 02 corresponding to the cartridge bottom cover; when the mating part 021 is exposed at the bottom end of the airway support 7 at the bottom of the cartridge bottom cover 8, it is in a state of structural interference with the airway support 7, and the cigarette rod assembly 02 cannot be mated with the cartridge bottom cover 8.

[0020] like Figure 1 As shown, the airway support 7 is pressed inward so that its bottom is flush with the bottom cover 8 of the e-liquid cartridge; at this time, the oil inlet 21 is in the open state, and there is no structural interference between the e-liquid assembly 02 and the e-liquid cartridge assembly, so they can be fully assembled; the atomizing core 4 can obtain power supply to atomize the e-liquid.

[0021] like Figure 2 As shown, the bottom of the airway support 7 is pulled out; the axial movement of the airway support 7 synchronously drives the lower support 6, the atomizing tube 2, and the oil storage cotton 3 and atomizing core 4 inside the atomizing tube 2 to be moved to the bottom of the stroke; at this time, the oil inlet 21 of the atomizing tube 2 enters into the oil cup support 5 and is sealed by the oil cup support 5. In this state, the e-liquid in the oil cup 1 cannot enter the oil storage cotton 3, preventing oil leakage from the atomizing channel. However, there is also structural interference between the e-cigarette assembly 02 and the cartridge assembly, preventing the atomizing core 4 from receiving power.

[0022] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining parts are not related to the implementation of the aforementioned scheme; they will not be described in detail here.
