[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, Figure 1 is a schematic diagram of the three-dimensional structure of the atomizer 10 provided in an embodiment of the present application, Figure 2 is an exploded schematic diagram of the atomizer 10 provided in an embodiment of the present application, Figure 3 yes Figure 1 The schematic diagram of the cross-sectional structure of the atomizer 10 along the AA direction is shown. Figure 4 yes Figure 1The schematic diagram of the cross-sectional structure of the atomizer 10 along the AA direction is shown. Figure 5 yes Figure 1 The cross-sectional structure diagram of the atomizer 10 along the BB direction is shown.

[0039] The present application discloses an atomizer 10, which includes an oil tank shell 11, a heating core 12, a seal 15, a base 16, a first conductive electrode 163, and a second conductive electrode 18, wherein the heating core 12 and the seal 15 are at least partially accommodated in the oil tank shell 11, an opening is provided on one side of the oil tank shell 11, and the seal 15 is provided at the open end of the oil tank shell 11.

[0040] The oil storage space 51 for accommodating the atomized matrix is ​​defined in the oil storage housing 11. Specifically, Figure 4 as well as Figure 5 As shown, the oil tank housing 11 includes an integrally formed outer tube 112, an inner tube 111 and a connecting wall 114, wherein the inner tube 111 is located inside the outer tube 112, one end of the inner tube 111 and the outer tube 112 is connected by a connecting wall 114, and the other end is open, and the seal 15 is sealed at the open end with an opening, and the outer tube 112, the inner tube 111, the inner wall surface of the connecting wall 114 and the seal 15 cooperate to form an oil storage space 51, and an atomization channel 52 is formed in the inner tube 111. The inner tube 111 is used to divide the oil tank shell 11 into an oil storage space 51 and an atomization channel 52. The inner tube 111 is provided with an oil inlet hole 1111 for connecting the oil storage space 51 and the atomization channel 52. The heating core 12 is arranged in the atomization channel 52 and at least partially opposite to the oil inlet hole 1111. The heating core 12 is used to atomize the oil storage space 51 and conduct the atomization matrix in the atomization space through the oil inlet hole 1111 to generate an aerosol. The aerosol flows along the atomization channel 52.

[0041] The heating core 12 includes a second oil-absorbing member 122 and an electric heating element 123. The second oil-absorbing member 122 is made of cotton, fiber, woven fabric or porous ceramics, and the electric heating element 123 is made of conductive metal, graphene or carbon nanotubes. The second oil-absorbing member 122 is used to absorb the atomized matrix in the oil storage space 51 from the oil inlet hole 1111, and the electric heating element 123 is used to heat the atomized matrix absorbed by the second oil-absorbing member 122 to generate aerosol. The electric heating element 123 is wrapped around the outer periphery of the second oil-absorbing member 122, or the electric heating element 123 is wrapped inside the second oil-absorbing member 122. For example, the electric heating element 123 is printed, deposited, sintered or physically embedded on the inner wall of the ceramic tube, or a heating wire is wrapped around the oil-absorbing cotton. In some other examples, the heating core 12 further includes a first oil absorbing member 121, wherein the first oil absorbing member 121 is sleeved on the outer periphery of the second oil absorbing member 122, and the electric heating element 123 is arranged inside the second oil absorbing member 122. Usually, the first oil absorbing member 121 is oil absorbing cotton or fiber, and the second oil absorbing member 122 is ceramic. The oil absorbing cotton or fiber has the advantages of good taste and stable oil conduction, and the porous ceramic has the advantage of stable chemical properties. The first oil absorbing member 121 and the second oil absorbing member 122 are combined with cotton or fiber materials and porous ceramics, so that the oil conduction is more stable and the stability of the heating core 12 is improved.

[0042] Compared with the prior art in which the heating core 12 is assembled in a separate metal tube, which is then installed in the oil tank shell and connected to the smoking nozzle, the present application does not require a sealing ring. An integrally formed oil tank shell 11 is provided, and a cavity is formed between the outer tube 112, the inner tube 111 and the connecting wall 114 of the oil tank shell 11, which completely separates the oil storage space 51 from the atomization channel 52, so that the atomized matrix can only be guided into the atomization channel 52 through the oil inlet hole 1111, thereby avoiding the prior art in which the smoke oil penetrates into the atomization channel 52 from the connection between the metal tube and the smoking nozzle due to assembly errors, causing the unatomized atomized matrix to be directly inhaled by the user, resulting in an uncomfortable taste.

[0043] refer to Figure 4 as well as Figure 5 As shown, the inner tube 111 and the outer tube 112 of the oil tank shell 11 are cylindrical, and the inner tube 111 and the outer tube 112 are arranged around the same central axis (not shown in the figure), and the connecting wall 114 extends from one end of the inner tube 111 to one end of the outer tube 112. The connecting wall 114 is arranged perpendicular to the central axis, which facilitates processing and reduces the scrap rate.

[0044] In some examples, the oil tank housing 11 further includes a mouthpiece 113, which is arranged on the side of the connecting wall 114 away from the inner tube 111 of the outer tube 112. The mouthpiece 113 is provided with a through-smoking hole 53 corresponding to the atomization channel 52, and the smoking hole 53 is communicated with the atomization channel 52. The aerosol formed by heating the heating core 12 flows along the atomization channel 52 to the smoking hole 53 to be inhaled by the user. Furthermore, the mouthpiece 113 is integrally formed with the outer tube 112, the inner tube 111, and the connecting wall 114, which has the advantages of convenient processing and better integrity. In other examples, the mouthpiece 113 can also be made of different materials from the outer tube 112 and the inner tube 111, and they are assembled with each other.

[0045] It should be noted that the one-piece molding process includes but is not limited to injection molding, extrusion molding, hot pressing molding, stamping molding, sintering molding or CNC one-piece molding, etc. Technical personnel in this field can select the processing technology according to the material of the oil tank shell 11, and this application does not make specific limitations.

[0046] In some instances, the oil tank shell 11 is made of a transparent material or a translucent material, and the transparent or translucent material allows users to observe the amount of atomized matrix in the oil tank space. Exemplarily, the oil tank shell 11 is made of glass, quartz, agate, jade or ceramic, preferably glass, which has the advantages of stable chemical properties, mature sintering technology, and low production cost. This avoids the problem in the prior art that the metal tube undergoes a long-term chemical reaction with the atomized matrix, contaminating the atomized matrix and causing adverse effects on the user's health.

[0047] In some instances, such as Figure 4 and Figure 6 As shown, the heating core 12 is arranged in the atomization channel 52 and close to one end of the sealing member 15, and the inner tube 111 is provided with at least one oil inlet hole 1111 corresponding to the heating core 12, and the oil inlet hole 1111 is used to make the oil storage space 51 communicate with the atomization channel 52 so that the heating core 12 can be filled with oil, and the oil inlet hole 1111 can be set as one or more windows, or one or more holes, or a combination of the two, etc., and the present disclosure is not limited thereto. The number and size of the oil inlet holes 1111 can be set as needed, for example, according to a predetermined atomization substrate flow rate.

[0048] like Figure 4 , Figure 5 as well as Figure 8 As shown, the atomizer 10 further includes a sealing member 15, which seals the opening end of the oil tank housing 11 away from the smoking nozzle 113, referring to Figure 4 and Fig. 9As shown, the end face of the seal 15 facing the oil storage space 51 is arranged with a descending slope, that is, the surface of the seal 15 facing the oil storage space 51 gradually decreases from the outer peripheral end to the center in an inclined slope. After the seal 15 is inserted into the end of the oil storage space 51, the oil inlet hole 1111 is located at the junction of the surface of the seal 15 facing the oil storage space and the oil storage space 51. The oil inlet hole 1111 can be partially extended into the seal 15 and blocked, and the oil inlet hole can also be flush with the surface of the seal along the lowest point of the inner tube and the outer tube axial direction, so that when the amount of atomized matrix is ​​small, it can be absorbed by the heating core 12 through the oil inlet hole 1111 along the inclined slope, which helps to make full use of the atomized matrix in the oil storage space 51. A first through hole 15a is opened in the middle of the seal 15, and the first through hole 15a is connected to the atomization channel 52 of the inner tube 111.

[0049] refer to Figure 7 as well as Figure 8 As shown, the atomizer 10 includes a base 16 , and the base 16 is provided with at least one air flow channel 16 a , and the air flow channel 16 e is communicated with the atomization channel 52 .

[0050] In some instances, the seal 15 is made of a sealing rubber plug that can be punctured and can restore itself to its original shape after puncture. The base 16 is provided with at least one oil filling hole 16d, and each oil filling hole 16d corresponds to the sealing rubber plug. The specific thickness of the seal 15 is between 3.0 mm and 3.5 mm, for example, 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, and 3.5 mm. Those skilled in the art can adjust it according to the volume of the oil storage space 51 to ensure good sealing performance after easy puncture and recovery without oil leakage.

[0051] In some embodiments, Figure 7 As shown, the base 16 includes a bottom wall 161 and a side wall 162, and a accommodating space 16b is defined in the base 16. One end of the outer tube 112 away from the smoking nozzle 113 extends into the accommodating space 16b. The bottom wall 161 of the base 16 corresponding to the accommodating space 16b is provided with a second through hole 16a corresponding to the first through hole 15a of the seal 15, and the second through hole 16a is communicated with the first through hole 15a. At least one air hole 16c is provided on the side wall 162 of the base 16 corresponding to the accommodating space 16b. The airflow channel 16e is defined on the bottom wall 161 of the base 16 corresponding to the accommodating space 16b and extends from the air hole 16c to the second through hole 16a. The oil filling hole 16d is provided on the bottom wall 161 of the base 16 corresponding to the accommodating space 16b.
