Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, and in particular to a split-type atomization device and its electronic cigarette. Background Technology

[0002] Electronic cigarettes (also known as "electronic cigarette packs") are electronic delivery systems that use an atomizing matrix to generate an aerosol for a user to inhale. The atomizing matrix can be a liquid (e.g., e-liquid) or a solid or gel (e.g., e-cream paste).

[0003] Electronic cigarettes include an atomizer and a power supply device electrically connected to the atomizer. The atomizer includes a liquid storage component for storing e-liquid and an atomizing component for heating the e-liquid and generating vapor. Normally, the liquid storage chamber on the liquid storage component and the atomizing chamber on the atomizing component are always in liquid communication and are manufactured as a single unit. This cannot meet the need for separate transportation of the liquid storage component and the atomizing component, limiting the user's freedom of choice. It is necessary to provide an electronic cigarette that can be stored and transported separately and can be used normally when combined. Summary of the Invention

An atomizing channel is formed inside the atomizing tube. A smoke guide channel is provided inside the smoke guide tube. The two ends of the smoke guide channel are respectively connected to the atomizing channel and the smoking port. The heating core includes an oil-absorbing component and a heating element. An oil-passing area is formed on the tube wall of the atomizing tube. The oil-absorbing component extends into the receiving cavity or is exposed in the receiving cavity from the oil-passing area. The oil-absorbing component abuts against the oil storage component.

[0014] In one embodiment, the atomizing assembly further includes a base and a sealing plug. The first housing has an opening at one end away from the mouthpiece and the sealing plug is installed therein. The base is located on the side of the sealing plug away from the mouthpiece. The base and the sealing plug are respectively provided with a first air hole and a second air hole that communicate with the atomizing channel.

This detachable modular structure design facilitates separate transportation of accessories. Different flavored oil tanks and atomizing components can be used, offering greater variety and allowing users to try more flavors. Simultaneously, both the receiving cavity and the oil storage cavity store e-liquid, resulting in a larger storage capacity. Once the e-liquid is depleted, only the oil tank needs to be replaced, reducing user costs. The through-hole design on the oil tank, combined with the atomizing component assembly, ensures a more stable structural connection. Compared to simply placing the oil tank at the corners, this increases its volume, allowing for more e-liquid storage. Furthermore, the first sealing cap, second sealing cap, and sealing plug ensure airtightness during separate transportation of the accessories. The filled e-liquid can also be stored for a long time. Assembly of the oil tank and atomizing component is simple and quick, offering high playability. Finally, the mouthpiece is located on the atomizing component, resulting in a more novel structure.

The oil tank body 1 has a first oil passage hole 14 communicating with the oil storage cavity 111. Specifically, the first oil passage hole 14 is formed on the oil tank seat 13 and the sealing element 12. E-liquid is stored in the oil storage cavity 111, and the first oil passage hole 14 is sealed during transportation. In some examples, the first oil passage hole 14 is provided with a removable first sealing cover 142, which seals the first oil passage hole 14. The first sealing cover 142 can be detachably connected to the oil tank seat 13 by means of snap-fit, plug-in, interference fit or magnetic attraction. In other examples, the first sealing cap 142 may be fixedly installed at the first oil passage 14 and fixedly connected to the oil tank 13. The first sealing cap 142 is made so that it can be easily pierced to open the first oil passage. For example, the first sealing cap 142 may be made of silicone film or kraft paper, etc. When the user uses it, after opening the first sealing cap 142 and assembling the atomizing component 2 with the oil tank 1, the e-liquid will flow out from the first oil passage 14 and be transferred to the atomizing component 2.

[0050] Reference Figure 4 , 5 7. In some embodiments, the atomizing component 2 includes a first housing 21, which has a main body 211 and a protrusion 212. The protrusion 212 protrudes from one end of the main body 211. During assembly, the through hole 112 is adapted to the protrusion 212. A receiving cavity 213 for receiving the atomizing matrix is ​​formed inside the first housing 21. Specifically, the receiving cavity 213 is distributed within the main body 211 and the protrusion 212, and the atomizing core 22 is installed inside the protrusion 212. The first housing 21 is provided with a second oil passage 24 communicating with the receiving cavity 213. When the oil tank 1 and the atomizing component 2 are assembled and connected, the oil tank 1 is sleeved on the outer periphery of the protrusion 212 through the through hole 112. The first oil passage 14 is connected to the second oil passage 24. The receiving cavity 213 is provided with an atomizing core 22 for heating the atomizing matrix. The atomizing component 2 and the oil tank 1 of this application can be stored or transported separately. When in use, the two are assembled together.

[0054] In some embodiments, the oil storage chamber 111 of the oil tank 1 and the receiving chamber 213 of the atomizing component 2 are both used to store the atomizing matrix, resulting in a larger oil storage capacity. At the same time, the oil storage component 25 fills the receiving chamber 213 completely. Filling it completely can maximize the use of the space in the receiving chamber 213 and increase the oil storage capacity. Of course, it can also be left unfilled, as long as the function of oil storage is achieved.

[0055] In some embodiments, the oil reservoir 25 and the oil guide 141 are made of cotton or fiber, respectively.

The two ends of the smoke guide channel 301 are respectively connected to the atomizing channel 223 and the smoking port 231. The heating element 222 includes an oil-absorbing component 224 and a heating element 225. An oil-passing area 226 is formed on the wall of the atomizing tube 221. The oil-absorbing component 224 extends at least partially into or is exposed within the receiving cavity 213 from the oil-passing area 226. The oil-absorbing component 224 abuts against the oil-storing component 25. The e-liquid stored in the oil-storing component 25 is transferred to the oil-absorbing component 224. The heating element 225 heats the e-liquid on the atomizing oil-absorbing component 224, and the resulting vapor passes through the atomizing channel 223 and is finally discharged from the inhalation port 231 for the user to inhale.

[0058] The oil-passing area 226 can be a hole or notch opened in the wall of the atomizing tube 221. The oil-absorbing element 224 is installed inside the atomizing tube 221. In some examples, the oil-absorbing element 224 can be cotton or fiber, extending from the oil-passing area 226 and abutting against the oil storage element 25, or the oil-absorbing element 224 can be partially exposed relative to the receiving cavity 213 through the oil-passing area 226. In other examples, the oil-absorbing element 224 can be a rigid oil-absorbing body, such as ceramic, microporous glass, quartz, or mica, with the portion of the oil-absorbing element 224 exposed relative to the receiving cavity 213 through the oil-passing area 226. The heating element 225 is made of a conductive material that can generate heat when energized, such as conductive metal, graphite, graphene, or carbon-containing nanotube materials.

[0059] In some embodiments, the atomizing assembly 2 further includes a base 27 and a sealing plug 26. The first housing 21 has an opening at one end away from the mouthpiece 23 and the sealing plug 26 is installed therein.

The base 27 and the sealing plug 26 are respectively provided with a first air hole 271 and a second air hole 261 communicating with the atomizing channel 223. The sealing plug 26 is provided to prevent the e-liquid in the receiving cavity 213 from leaking and contaminating the internal space of the electronic cigarette. The first air hole 271 and the second air hole 261 are used for air intake.

[0060] In some embodiments, an upper absorbent cotton 28 is provided around the connection between the smoke guide tube 30 and the mouthpiece portion 23 to absorb condensed e-liquid produced by the mouthpiece portion 23. Preferably, the upper absorbent cotton 28 wraps around one end of the smoke guide tube 30 to better catch condensed e-liquid flowing back from the mouthpiece portion 23. In other embodiments, the upper absorbent cotton 28 may also wrap around the end of the mouthpiece portion 23, or simultaneously surround both the smoke guide tube 30 and the mouthpiece portion 23.

[0061] In some embodiments, a lower oil-absorbing cotton 29 for preventing oil leakage is provided between the sealing plug 26 and the base 27. The lower oil-absorbing cotton 29 is located around the lower end of the atomizing tube 221. The lower oil-absorbing cotton 29 mainly works with the sealing plug 26 to jointly prevent oil leakage.

[0062] In some embodiments, the oil tank 1 and the atomizing component 2 are detachably connected by means of snap-fit, plug-in, interference fit or magnetic attraction.

The third housing 31 is provided with an air inlet 311 that communicates with the atomization channel 223 in the atomizing assembly 2. A battery cell 34 and a control board 33 are installed inside the third housing 31. The control board 33 is electrically connected to the battery cell 34. The base 32 is provided with electrodes. The battery cell 34 is electrically connected to the atomizing core 22 through the electrodes. The control board 33 is provided with a microphone assembly (not shown in the figure). When the user smokes, airflow enters the electronic cigarette through the air inlet 311. The microphone assembly senses the airflow, and then the control board 33 controls the battery cell 34 to supply power to the atomizing core 22. After the atomizing core 22 is powered on, it heats the e-liquid to produce smoke. The produced smoke passes through the atomization channel 223 and is finally discharged from the smoking port 231 for the user to inhale.
