Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more specifically to an atomizer. Background Technology

[0002] The working principle of an atomizer is generally to deliver e-liquid stored in the reservoir to the atomizer coil through capillary action of the reservoir cotton. The coil then heats and atomizes the e-liquid into an aerosol for the user to inhale. Currently, most mainstream atomizers on the market use a single reservoir structure, meaning all e-liquid is stored in one reservoir. This makes it difficult to increase capacity and results in shorter battery life. Furthermore, in a single reservoir structure, e-liquid flows back into the reservoir after the user inhales, causing the inhaled e-liquid to mix with the uninhaled e-liquid, leading to a decline in flavor. For example, in the patent document with publication number CN222707589U, two reservoirs are used for refilling to improve battery life, but the overall structure is more complex. During inhalation, the atomizer needs to be inverted multiple times to refill, resulting in a poor user experience. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one object of this invention is to provide an atomizer comprising: A housing, wherein the housing contains a main oil tank; A secondary oil tank is located inside and connected to the main oil tank. When the shell is operated to be inverted and then upright, the e-liquid stored in the main oil tank flows into the secondary oil tank. An atomizing component is disposed within and connected to the auxiliary oil tank, so that the e-liquid in the auxiliary oil tank enters the atomizing component.

[0004] Preferably, the atomizing component includes: Atomizing tube, which is fixed in the main oil tank and connected to the auxiliary oil tank through the first oil inlet; Oil-retaining cotton is disposed inside the atomizing tube and covers the first oil inlet hole; The atomizing core is disposed inside the oil storage cotton and is connected to the oil storage cotton through a second oil inlet hole.

[0005] Preferably, the housing also includes a battery compartment for installing batteries, the main oil tank surrounds the auxiliary oil tank and the battery compartment, and the battery compartment is sealed to the bottom of the auxiliary oil tank.

[0006] Preferably, the auxiliary oil tank includes: A sleeve portion is fitted onto the circumferential surface of the atomizing tube and is sealed to the battery compartment. The liquid storage section has its bottom connected to the sleeve portion and is spaced around the outer periphery of the atomizing tube. The top of the liquid storage section has an opening for the e-liquid to flow in.

[0007] Preferably, the liquid storage section includes a first curved section and a second curved section connected to each other, wherein the first curved section is located on one side of the atomizing tube in the radial direction and abuts against the peripheral wall of the main oil tank, and the second curved section is located on the other side of the atomizing tube in the radial direction and is spaced apart from the peripheral wall of the main oil tank.

[0008] Preferably, the liquid storage section further includes a fan-shaped bottom connected to the first curved section, the inner edge of the fan-shaped bottom abutting against the atomizing tube, and the outer edge of the fan-shaped bottom connected to the first curved section.

[0009] Preferably, one end of the oil storage cotton is provided with a first sealing ring, which extends to abut against the inner wall of the main oil chamber, and the other end of the oil storage cotton is provided with a second sealing ring, which is sleeved on the circumferential surface of the atomizing core.

[0010] Preferably, the sleeve portion has a fitting portion on the side opposite to the oil storage portion, the fitting portion is embedded in the battery compartment, and a third sealing ring is fitted on the outer peripheral surface of the fitting portion, the third sealing ring abutting against the inner peripheral surface of the battery compartment.

[0011] Preferably, the inner circumferential surface of the fitting part is provided with oil-absorbing cotton, and the oil-absorbing cotton is in close contact with the battery compartment.

[0012] Preferably, the housing is further provided with an atomizing channel, which extends from the outside of the housing to communicate with the atomizing core.

[0013] The above-described solution of the present invention has at least the following beneficial effects: The atomizer provided by this invention stores e-liquid in the main tank. During use, the user can invert and then upright the atomizer, allowing the secondary tank to receive some of the e-liquid flowing from the main tank. This e-liquid can then enter the atomization assembly from the secondary tank. This ensures that the atomizer's battery life is maintained by the main tank during vaping, while also preventing e-liquid from flowing back into the main tank after vaping. This prevents vaped and unvaped e-liquid from mixing, improving the vaping experience. Furthermore, it eliminates the need for frequent inversion of the atomizer to refill e-liquid during vaping, resulting in a better user experience.

[0023] The atomizer of this invention, according to an embodiment of the present invention, will now be described in detail with reference to the accompanying drawings.

[0024] Reference Figures 1 to 3As shown, the atomizer provided in this embodiment of the invention includes: a housing 10, a secondary oil tank 20, and an atomizing component 30. The housing 10 has a main oil tank 11 with a capacity of 10ml or more. The secondary oil tank 20 is located inside the main oil tank 11 and is interconnected with it. The capacity of the secondary oil tank 20 is 2ml or more. In use, by flipping the housing 10, e-liquid can flow into the opening 226 of the secondary oil tank 20 from the main oil tank 11. When the housing 10 is turned upright again, the e-liquid stored in the main oil tank 11 can flow into the secondary oil tank 20 from the opening 226. The atomizing component 30 is located inside the secondary oil tank 20 and is interconnected with it, so that the e-liquid in the secondary oil tank 20 can enter the atomizing component 30.

[0025] Reference Figure 2 and Figure 3 As shown, the atomizing component 30 includes: an atomizing tube 31, an oil-retaining cotton 32, and an atomizing core 33. The atomizing tube 31 is fixed inside the main oil tank 11 and connected to the secondary oil tank 20 through a first oil inlet 311. The oil-retaining cotton 32 is disposed inside the atomizing tube 31 and covers the first oil inlet 311. The secondary oil tank 20 and the oil-retaining cotton 32 are connected through the first oil inlet 311, so that the e-liquid in the secondary oil tank 20 can enter the oil-retaining cotton 32 through the first oil inlet 311 and be absorbed by the oil-retaining cotton 32 into the atomizing core 33 for atomization. Preferably, the first oil inlet 311 should be located at the lower end of the atomizing tube 31 and close to the secondary oil tank 20. The bottom position ensures that the e-liquid in the auxiliary oil tank 20 can completely enter the oil reservoir 32, ensuring that the e-liquid in each vape is completely absorbed by the oil reservoir 32. Since the atomizer core 33 is located inside the oil reservoir 32 and is connected to the oil reservoir 32 through the second oil inlet 331, the e-liquid can enter the atomizer core 33 from the oil reservoir 32 and be atomized for the user to vape. Optionally, the oil reservoir 32 can absorb more than 2ml of oil, ensuring that the amount of oil stored in the oil reservoir 32 and the auxiliary oil tank 20 can increase the number of vape strokes during vaping, avoiding frequent inversion operations and providing a better user experience.

[0026] Furthermore, the housing 10 also has a battery compartment 12 for installing the battery 40. The main oil compartment 11 is arranged around the auxiliary oil compartment 20 and the battery compartment 12, and the battery compartment 12 is sealed to the bottom of the auxiliary oil compartment 20. By electrically connecting the battery 40 to the atomizer core 33, the atomizer core 33 can be powered by the battery 40 when heating and atomizing the e-liquid. The overall structure is more compact and simple, avoiding e-liquid leakage caused by the separate structure. Reference Figure 4 and Figure 5As shown, the auxiliary oil tank 20 includes a sleeve part 21 and a liquid storage part 22. The sleeve part 21 is fitted onto the circumferential surface of the atomizing tube 31 and is sealed to the battery compartment 12. The bottom of the liquid storage part 22 is connected to the sleeve part 21 and is spaced around the outer periphery of the atomizing tube 31. An opening 226 is formed at the top of the liquid storage part 22 for the e-liquid to flow in.

[0027] In this embodiment, the auxiliary oil tank 20 can be made of materials such as silicone. By connecting and fixing the sleeve 21 to the atomizing tube 31 and placing them together in the main oil tank 11 of the atomizer, the auxiliary oil tank 20 can be tightly assembled with the atomizing tube 31. When the atomizer is inverted and then upright so that the e-liquid enters the auxiliary oil tank 20 from the main oil tank 11, the e-liquid can be stored in the liquid storage section 22. Furthermore, the sleeve 21 and the atomizing tube 31 can be sealed to prevent the e-liquid from leaking out of the auxiliary oil tank 20.

[0028] In a preferred embodiment, the liquid reservoir 22 includes a first curved portion 221 and a second curved portion 222 connected to each other. The first curved portion 221 is located on one side of the atomizing tube 31 in the radial direction, and the second curved portion 222 is located on the other side of the atomizing tube 31 in the radial direction. The outer diameter of the first curved portion 221 is larger than the outer diameter of the second curved portion 222, so that the first curved portion 221 can abut against the inner wall of the main oil tank 11. The second curved portion 222 is spaced apart from the inner wall of the main oil tank 11, thereby allowing the liquid to be absorbed during the atomizer inversion process. In this configuration, e-liquid can flow from the gap between the second curved section 222 and the main oil tank 11 into the opening 226 of the auxiliary oil tank 20. When the atomizer is upright, since the first curved section 221 abuts against the inner wall of the main oil tank 11, the e-liquid can flow into the auxiliary oil tank 20 from the opening 226 of the first curved section 221, ensuring that more e-liquid enters the auxiliary oil tank 20. It can be understood that the outer diameter of the first curved section 221 can be equal to the inner diameter of the main oil tank 11, and the outer diameter of the second curved section 222 is smaller than the inner diameter of the main oil tank 11.

[0029] More preferably, the liquid storage section 22 further includes a fan-shaped bottom 223 connected to the first curved section 221. The inner edge of the fan-shaped bottom 223 abuts against the atomizing tube 31, and the outer edge of the fan-shaped bottom 223 is connected to the first curved section 221. By providing the first curved section 221 and the fan-shaped bottom 223, a first transition oil cavity 224 is defined between the first curved section 221, the atomizing tube 31, and the fan-shaped bottom 223. This allows the oil storage capacity of the auxiliary oil cavity 20 to be increased while ensuring that the first curved section 221 abuts against the inner wall of the main oil chamber 11. It is understood that the bottom of the second curved section 222 is connected to the sleeve section 21, and the diameter of the second curved section 222 is slightly larger than the diameter of the sleeve section 21, thus defining a second transition oil cavity 225 between the second curved section 222 and the atomizing tube 31. After the e-liquid enters the first transition oil chamber 224 from the opening 226 of the first curved portion 221, since the first transition oil chamber 224 and the second transition oil chamber 225 are interconnected, the e-liquid can flow from the first transition oil chamber 224 into the second transition oil chamber 225, and wrap the atomizing tube 31 so that it enters the oil storage cotton 32 from the first oil inlet 311. This ensures that more e-liquid can be stored in the auxiliary oil tank 20 during the vaping operation, ensuring that there are more vaping ports. In some other embodiments, when the atomizer adopts a cuboid structure and the main oil tank 11 is a cuboid structure, the auxiliary oil tank 20 can adopt a corresponding cuboid structure, and can achieve the above function by adopting a structure in which the first curved portion 221 is attached to the inner wall of the main oil tank 11, and the second curved portion 222 is spaced apart from the inner wall of the main oil tank 11.

[0030] Reference Figures 2 to 4 As shown, one end of the oil-collecting cotton 32 is provided with a first sealing ring 50, which extends to abut against the inner wall of the main oil chamber 11. This allows the e-liquid to be sealed within the main oil chamber 11 by the first sealing ring 50 after the atomizer is inverted, preventing leakage from the gap between the main oil chamber 11 and the oil-collecting cotton 32, thus improving the sealing performance. The other end of the oil-collecting cotton 32 is provided with a second sealing ring 60, which is fitted onto the circumferential surface of the atomizing core 33. This allows the e-liquid absorbed by the oil-collecting cotton 32 to be sealed within the atomizing tube 31 by the second sealing ring 60. To prevent e-liquid from leaking from the atomizing tube 31 into the battery compartment 12, a more preferred embodiment is provided with a fitting part 23 on the side of the sleeve part away from the oil storage part. The fitting part 23 is embedded in the battery compartment 12, and a third sealing ring 70 is fitted on the outer peripheral surface of the fitting part 23. The third sealing ring 70 abuts against the inner peripheral surface of the battery compartment 12, so that when the main oil compartment 11 is filled with e-liquid, the gap between the battery compartment 12 and the auxiliary oil compartment 20 can be sealed by the third sealing ring 70, preventing e-liquid from entering the battery compartment 12 from the main oil compartment 11, resulting in a better sealing effect.

[0031] Furthermore, the inner circumferential surface of the fitting part 23 is provided with oil-absorbing cotton 80, and the oil-absorbing cotton 80 is in close contact with the battery compartment 12. The battery 40 passes through the oil-absorbing cotton 80 and the auxiliary oil compartment 20 and is connected to the atomizing core 33. Thus, the e-liquid can be absorbed by the oil-absorbing cotton 80, preventing the e-liquid from leaking from the atomizing core 33 into the battery compartment 12, which is safer.

[0032] Furthermore, the housing 10 is also provided with an atomization channel 12, which extends from the outside of the housing 10 to communicate with the atomizing core 33. The atomization channel 12 is connected to the suction hole of the housing 10, so that during the user's inhalation, the e-liquid atomized by the atomizing core 33 can be drawn out through the atomization channel 12, making the overall structure simpler.

[0033] The atomizer provided by this invention stores e-liquid in the main tank 11. During use, the user can invert and then upright the atomizer, allowing the secondary tank 20 to receive and hold some of the e-liquid flowing into the main tank 11. This e-liquid can then enter the atomization assembly 30 from the secondary tank 20. This ensures the atomizer's battery life during vaping while preventing e-liquid from flowing back into the main tank 11 after vaping. It also prevents vaped e-liquid from mixing with unvaped e-liquid, improving the vaping experience. Furthermore, it eliminates the need for frequent inversion of the atomizer to refill e-liquid during vaping, resulting in a better user experience.
