It is evident that this type of atomizer has a large number of components, a complex assembly process, and high production costs. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an electronic atomizer that can replace the steel tube for installing the atomizer core by lengthening the internal conduit of the oil cup, thereby reducing the number of parts, simplifying the assembly process, and reducing production costs.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] This application provides an electronic atomizer, the electronic atomizer comprising:

[0007] An oil cup includes an integrally molded outer shell and a conduit. The outer shell has a suction nozzle end and an open end arranged longitudinally opposite each other. The conduit is located inside the outer shell and one end is connected to the suction nozzle end, while the other end extends toward the open end. A liquid storage cavity is defined between the outer wall of the conduit and the inner wall of the outer shell.

[0009] A heating element is disposed in the portion of the first oil guide body located within the conduit; and

[0010] The base is at least partially fixed to the open end to seal the liquid storage cavity.

[0011] In one possible implementation, the first oil guide body is located in the internal through hole of the conduit, and the internal through hole is provided with a limiting part that can axially limit the first oil guide body.

[0012] In one possible implementation, a stepped hole is provided at the end of the internal through-hole of the conduit away from the nozzle end, the stepped hole including a first hole segment away from the nozzle end and a second hole segment close to the nozzle end;

[0013] The diameter of the first hole segment is larger than the diameter of the second hole segment;

[0014] The shoulder surface at the junction of the first hole segment and the second hole segment constitutes the limiting part.

[0015] In one possible implementation, the sidewall of the conduit is provided with an oil guide port, and the first oil guide body communicates with the liquid in the reservoir through the oil guide port.

[0016] In one possible implementation, the oil guide port extends longitudinally and passes through the end of the conduit away from the nozzle end.

[0017] In one possible implementation, the first oil guide body includes:

[0018] The main body is cylindrical and is fitted inside the end of the guide tube away from the nozzle.

[0019] An oil-absorbing part is connected to the main body and is at least partially located in the oil guide port;

[0020] The heating element is disposed on the main body.

[0021] In one possible implementation, the base is provided with an air intake channel and a mounting cavity communicating with the air intake channel; one end of the conduit away from the nozzle end is inserted into the mounting cavity.

[0022] In one possible implementation, a second oil guide body is provided outside the conduit. The second oil guide body is located at one end of the base facing the liquid storage cavity and is in liquid communication with the liquid storage cavity to guide the liquid in the liquid storage cavity to the first oil guide body.

[0023] In one possible implementation, the end of the base facing the liquid storage cavity is located inside the housing and is provided with a receiving groove; the mounting cavity is located at the bottom of the receiving groove and extends away from the nozzle end;

Detailed Implementation

[0036] This application provides an electronic atomizer with a novel structure. By optimizing the oil cup structure, the atomizer core can be installed using the oil cup itself instead of a steel tube, thereby reducing the number of parts, simplifying the assembly process, and lowering production costs.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Please see Figure 1 as well as Figures 3 to 5 This application provides an electronic atomizer. The atomizer core includes an oil cup 1, a first oil guide body 6, a heating element 7, and a base 3. The oil cup 1 includes an integrally formed outer shell 13 and a conduit 11. The outer shell 13 has a mouthpiece end and an open end arranged longitudinally opposite each other. The open end has a relatively larger cross-sectional area, and the mouthpiece end has a relatively smaller cross-sectional area. The mouthpiece end is provided with a suction port 10. The conduit 11 is located inside the outer shell 13. One end of the conduit 11 is located inside the suction port 10 and integrally formed therewith. The other end of the conduit 11 extends towards the open end of the outer shell 13, connects to the base 3, and communicates with the air intake channel 30 in the base 3. A liquid storage chamber 12 is defined between the inner wall of the outer shell 13 and the outer wall of the conduit 11 for storing a liquid medium (i.e., an electric liquid). The sub-atomizer contains an e-liquid or e-liquid used to generate vapor or a specific flavor; the base 3 is at least partially fixed to the open end of the outer casing 13 to seal the liquid reservoir 12; the first oil guide 6 is at least partially sleeved inside the end of the conduit 11 away from the suction port 10 and is in liquid communication with the liquid reservoir 12, meaning that the liquid medium in the liquid reservoir 12 can automatically immerse itself in the first oil guide 6; the heating element 7 is disposed in the portion of the first oil guide 6 located inside the conduit 11 to heat the first oil guide 6 and its internal liquid, so that at least a portion of the liquid medium is converted into a gaseous state. When airflow passes through the air intake channel 30 in the base 3, then through the conduit 11, and is output from the suction port 10, the gaseous medium formed by the heating of the liquid medium in the first oil guide 6 by the heating element 7 can mix with the airflow in the conduit 11 and be output from the suction port 10. As can be seen, in this electronic atomizer, since the first oil guide body 6 is directly installed in the conduit 11 inside the oil cup, there is no need for a steel pipe, which can reduce the number of parts, save materials, reduce production costs, and also simplify the user's maintenance work.

[0039] In some embodiments, the first oil guide 6 is located in the internal through-hole of the conduit 11, and the internal through-hole of the conduit 11 is provided with a limiting part that can axially limit the first oil guide 6. The end of the first oil guide 6 near the suction port 10 abuts against the limiting part. The limiting part can easily control the insertion of the first oil guide 6 into the conduit 11 to a suitable position, avoiding the first oil guide 6 from being inserted too deeply or too shallowly into the conduit 11. For example, please refer to Figure 2 and Figure 4 The internal through-hole of the conduit 11, away from the suction port 10, is provided with a stepped hole. This stepped hole includes a first section 111 away from the suction port 10 and a second section 112 near the suction port 10. The diameter of the first section 111 is larger than the diameter of the second section 112. The shoulder surface 113 at the junction of the first section 111 and the second section 112 constitutes the aforementioned limiting portion capable of axially limiting the first oil guide body 6. In other words, the first oil guide body 6 is installed inside the conduit 11 through the stepped hole, and the first oil guide body 6 is axially limited by the shoulder surface 113 of the stepped hole. Specifically, the stepped hole includes a first hole segment 111, a shoulder surface 113, and a second hole segment 112 connected in sequence. The first hole segment 111 is located at the end of the conduit 11 away from the suction port 10. The second hole segment 112 is closer to the suction port 10 than the first hole segment 111, and the diameter of the second hole segment 112 is larger than the diameter of the first hole segment 111. The inner ring side of the shoulder surface 113 is connected to the first hole segment 111, and the outer ring side of the shoulder surface 113 is connected to the second hole segment 112. However, it is not limited to this. In other embodiments, the first oil guide body 6 can also be limited by protrusions of other shapes or other methods. For example, a semi-circular boss or a columnar boss can be provided on the side wall of the internal through hole of the conduit 11, or the first oil guide body 6 can be limited by a protruding part outside the conduit 11. Thus, when the first oil guide body 6 is installed into the conduit 11, it is only necessary to insert the first oil guide body 6 into the conduit 11 until the first oil guide body 6 abuts against the limiting part.

[0040] In practice, it is recommended that the material of oil cup 1 be a food-grade material that is non-toxic and harmless to the human body, and that it has sufficient rigidity and thickness to ensure its structural stability and resistance to deformation.

[0041] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the heating element 7 in the first oil guide body 6 can be a mesh-like cylindrical heating wire, and the heating element 7 is attached to the cylindrical inner wall of the first oil guide body 6. Alternatively, in other embodiments, the heating element 7 can be embedded inside the first oil guide body 6. In specific implementation, it is sufficient to ensure that the heating element 7 can heat the first oil guide body 6 so that the liquid medium adsorbed inside it is vaporized by heat to form an aerosol for the user to inhale.

[0042] Please see Figure 2 In some embodiments, an oil guide port 110 is provided on the side wall of the conduit 11 away from the suction port 10. The first oil guide body 6 located inside the conduit 11 communicates with the liquid storage chamber 12 through the oil guide port 110, that is, the liquid medium in the liquid storage chamber 12 enters the first oil guide body 6 through the oil guide port 110 on the conduit 11. Specifically, the oil guide port 110 is located on the end side wall of the conduit 11 away from the suction port 10, extending from the side of the end opening of the conduit 11 towards the suction port 10 to a predetermined length, that is, the oil guide port 110 extends longitudinally (i.e., in a direction parallel to the conduit axis) and penetrates the end of the conduit 11 away from the suction nozzle end. Correspondingly, please refer to Figure 1 The first oil guide body 6 includes a main body 61 and an oil suction part 62. The main body 61 is cylindrical and sleeved inside the end of the conduit 11 away from the suction port 10, and is provided with a heating element 7. The oil suction part 62 is connected to the main body 61, and the oil suction part 62 is at least partially filled in the oil guide port 110 for absorbing liquid medium and transferring it to the main body 61. When the user inhales through the suction port 10, airflow passes through the internal through hole of the conduit 11. At this time, the gaseous medium formed by heating by the heating element 7 mixes with the airflow and is output to the user's mouth through the oil guide port 110.

[0043] Please see Figures 3 to 5 In the electronic atomizer provided in this application embodiment, a base 3 and an end cap 2 are provided at the end away from the inhalation port. The base 3 is located inside the outer shell 13 of the oil cup 1 and is used to seal the liquid storage chamber 12. The end cap 2 is connected to the open end of the outer shell 13 and fixes the base 3 inside the open end of the outer shell 13. Specifically, the base 3 is provided with an air inlet channel 30 and an installation cavity 311 communicating with the air inlet channel 30. The end of the conduit 11 away from the mouthpiece is inserted into the installation cavity 311 and communicates with the air inlet channel 30. Further, a sealing element 4 is provided between the outer periphery of the base 3 and the inner wall of the outer shell 13. That is, the sealing element 4 and the base 3 are sequentially fitted inside the open end of the outer shell 13 of the oil cup 1 and are limited and installed in the outer shell 13 of the oil cup 1 by the end cap 2. The base 3 is located within the seal 4. The interior of the base 3 and / or the space between the base 3 and the seal 4 form an air intake channel 30. One end of the air intake channel 30 opens to the external environment through a vent on the end cap 2, and the other end opens to the end of the conduit 11 furthest from the suction port 10. Thus, the air intake channel 30, the conduit 11, and the suction port 10 are sequentially connected to form an airflow path for the user to inhale. A circumferential air passage extending around the base 3 is formed between the base 3 and the seal 4. This circumferential air passage is part of the air intake channel 30, allowing the airflow entering the electronic atomizer to first rotate around one end of the base 3 before entering the conduit 11. This not only facilitates airflow filtration but also helps control airflow speed, improving the user experience.

[0044] Furthermore, the electronic atomizer also includes a second oil guide 5, which is sleeved outside the conduit 11 and in contact with the first oil guide 6. The second oil guide 5 is located at the end of the base 3 facing the liquid reservoir 12, communicating with the liquid in the reservoir 12 to guide the liquid within the reservoir 12 to the first oil guide 6. Specifically, as... Figure 4 As shown, the inner ring of the second oil guide 5 contacts the oil-absorbing portion 62 of the first oil guide 6 located in the oil outlet 110 of the conduit 11; the top of the second oil guide 5 contacts the liquid in the storage chamber 12. Thus, the second oil guide 5 can absorb the liquid in the storage chamber 12 and transfer it to the first oil guide 6. When the user inhales through the suction port 10, the airflow passes sequentially through the airflow channel in the base 3, the central through hole of the first oil guide 6, the internal through hole of the conduit 11, and the suction port 10. At this time, the liquid medium (usually called e-liquid or e-liquid) in the first oil guide 6 is heated by the heating element 7 to form a gaseous medium, which mixes with the airflow when the airflow passes through the central through hole of the first oil guide 6 to form an aerosol for the user to inhale, and then is output to the user's mouth through the oil outlet 110.

[0045] Please see Figure 4 and Figure 6 In some embodiments, the top of the base 3 is provided with a stepped countersunk hole 31 for installing the second oil guide body 5 and for inserting the conduit 11. Specifically, the end of the base 3 facing the liquid storage cavity 12 is located inside the outer shell 13 and is provided with a receiving groove 312; the bottom surface of the receiving groove 312 has an installation cavity 311 for inserting the conduit 11. The installation cavity 311 extends from the bottom of the receiving groove 312 in a direction away from the suction port 110 and communicates with the air intake channel 30 in the base 3. After the conduit 11 is inserted into the installation cavity 311, the oil guide port 110 on the conduit 11 communicates with the receiving groove 312 located outside the installation cavity 311. At this time, the second oil guide body 5 is located in the receiving groove 312 and between the oil guide port 110 and the liquid storage cavity 12.

[0046] Furthermore, in some embodiments, the end of the seal 4 away from the end cap 2 is provided with an annular protrusion 41 that engages and limits the top of the base 3. One end of the inner ring of the annular protrusion 41 is connected to the second oil guide body 5, and the other end is connected to the liquid storage cavity 12. Moreover, the cross-section of the inner ring of the annular protrusion 41 gradually increases along the direction close to the liquid storage cavity 12, so that the base 3 can be axially limited by the annular protrusion 41, and the area communicating with the outlet area of ​​the liquid storage cavity 12 can be expanded, so that the liquid in the liquid storage cavity 12 can smoothly enter the second oil guide body 5.

[0047] In practice, both the first oil guide body 6 and the second oil guide body 5 can be made of oil-absorbing cotton or other materials that can absorb and transfer liquid.
