Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to an oil-leakage-proof atomizing device. Background Technology

[0002] Because e-cigarette products contain liquid e-liquid, and the e-liquid tank and atomizer core are connected, the liquid e-liquid can easily leak out during transportation and storage when the tank encounters negative pressure or changes in ambient temperature, affecting the user experience.

[0003] To address this issue, the common leak-proof solution used in e-cigarette devices on the market is to install external sealing silicone and fill the inside with absorbent cotton. However, this measure only delays or reduces the possibility of leakage to a certain extent, and is still a passive protection. The external silicone seal can only cope with negative pressure environments, but under high temperatures, e-liquid can still leak inside the device. The internal absorbent cotton cannot completely absorb the seeping e-liquid, and the external silicone must be removed during use, causing the temporarily accumulated e-liquid to eventually flow out, seriously affecting the user experience and failing to fundamentally prevent leakage.

Detailed Implementation

[0018] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0019] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] like Figures 1 to 9As shown, this utility model discloses an oil leakage-proof atomizing device, including a housing 1, an oil tank located at the upper end of the housing 1, an atomizing chamber located at the lower end of the oil tank, an atomizing core 6 located in the atomizing chamber, and an oil seal assembly. The lower side wall of the atomizing core 6 has an oil inlet hole 11. The oil seal assembly includes a lifting sleeve 15, an oil seal silicone sleeve 7, a transmission gear 8, a drive gear 9, and a drive motor 10. The oil seal silicone sleeve 7 is fixedly connected to the upper end of the lifting sleeve 15 and fits around the lower end of the atomizing core 6. Two horizontally arranged positioning cylinders 16 are symmetrically arranged on the outer wall of the lower end of the lifting sleeve 15. A fixing tube capable of fixing the lower end of the atomizing core 6 is provided inside the atomizing chamber. 18 and a limiting tube 19 located around the fixed tube 18. The lower end of the lifting sleeve 15 is installed between the fixed tube 18 and the limiting tube 19. The limiting tube 19 is provided with a longitudinal sliding groove 20 that is adapted to the two positioning cylinders 16. The transmission gear 8 is sleeved on the limiting tube 19 and has a lifting inclined groove 17 on its inner wall that is adapted to the two positioning cylinders 16 respectively. The drive motor 10 is fixed on one side of the atomizing chamber. The drive gear 9 is connected to the drive motor 10 and meshes with the transmission gear 8. When the transmission gear 8 rotates, it can drive the lifting sleeve 15 and the oil seal silicone sleeve 7 to move up and down to control the opening and closing of the oil inlet 11.

[0022] When in transport mode, the drive motor 10 drives the drive gear 9 to rotate, which in turn drives the transmission gear 8 to rotate in one direction. At this time, the lifting groove 17 of the transmission gear 8 will drive the positioning cylinder 16 to move upward along the longitudinal slide groove 20, which in turn drives the lifting sleeve 15 and the oil seal silicone sleeve 7 to move upward. At this time, the oil seal silicone sleeve 7 can block the oil inlet hole 11 of the atomizing core 6, thereby closing the oil inlet channel and preventing oil leakage. When it is needed, the drive motor 10 reverses, which drives the oil seal silicone sleeve 7 to move downward, exposing its oil inlet hole 11. At this time, the oil in the oil tank can enter the atomizing core 6 for atomization.

[0023] This invention, by setting a liftable oil seal assembly, can control the opening and closing of the oil inlet channel between the atomizing core 6 and the oil tank, thereby preventing oil leakage when not in use and greatly improving the user experience.

[0024] In this utility model, the housing 1 includes an upper shell 2, an oil tank bottom cover 4, a bracket 5, and a lower shell 3. The oil tank bottom cover 4 is sealed to the lower end of the upper shell 2 to form the oil tank. One end of the oil tank bottom cover 4 is provided with a communicating channel 13 that communicates with the atomizing chamber and is fitted onto the oil seal silicone sleeve 7. The lower shell 3 is snapped to the upper shell 2. The bracket 5 is installed between the lower shell 3 and the oil tank bottom cover 4. The atomizing chamber is located on the bracket 5. The drive motor 10 is fixed on the bracket 5.

[0025] In this utility model, the upper end of the upper shell 2 is provided with a mouthpiece, and the upper end of the atomizing core 6 passes through the oil tank and is connected to the lower end of the mouthpiece through the upper sealing silicone 12 to form an air outlet channel.

[0026] In this invention, the fixed tube 18 is provided with a lower sealing silicone 21, and the lower sealing silicone 21 has an air inlet hole in the center for air intake.

[0027] In this utility model, the other end of the oil tank bottom cover 4 is provided with an oil inlet 14, and the oil inlet 14 is provided with an oil plug 22 to facilitate oil filling of the oil tank.

[0028] In this invention, the oil tank bottom cover 4 is snapped together with the bracket 5 for easy assembly.

[0029] In this utility model, the oil leakage prevention atomizing device also includes a power supply component disposed in the lower shell 3. The power supply component includes a battery and a circuit board, and the drive motor 10 and the battery are electrically connected to the circuit board.

[0030] In this utility model, the lower shell 3 is also provided with a control switch for controlling the operation of the drive motor 10, which is used to control the lifting and lowering of the oil seal assembly.

[0031] In this invention, the transmission gear 8 has a half-tooth structure, which can satisfy the meshing with the drive gear 9 without taking up too much space.

[0032] In this invention, the atomizing core 6 is provided with oil-absorbing cotton.

[0033] In the transportation state, the drive motor 10 drives the oil seal assembly to seal the oil inlet 11 of the atomizing core 6, physically isolating the e-liquid passage and ensuring that there is no risk of oil leakage under various environmental conditions. During use, the motor can be precisely adjusted to open and close the oil inlet 11 through a preset program. It is only opened when needed to ensure normal use of the product, and the oil inlet 11 is closed immediately after the product is no longer used, thereby fundamentally eliminating the possibility of oil leakage under any working condition.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
