In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0041] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.
[0042] The following will describe in detail an atomization host 100 provided in an embodiment of the present application through specific embodiments in conjunction with all the accompanying drawings of the specification.
[0043] Please refer to Figure 1 、 Figure 2 and Figure 3 , in one embodiment of the present utility model, an atomization host 100 is disclosed, which includes a mouthpiece 10 and an atomization assembly 20. The mouthpiece 10 is provided with an air suction cavity 102; the mouthpiece 10 is installed on the atomization assembly 20, and the atomization host 100 is provided with an oil storage cavity 30. The atomization assembly 20 includes a heating assembly 21, an inserted oil sealing part 23 and an oil sealing member 25. The atomization assembly 20 is provided with an atomization cavity 202 and an oil inlet hole 204. The oil sealing member 25 seals the opening of the oil storage cavity 30, and the oil sealing member 25 is provided with an oil injection hole 206. The oil injection hole 206 is a blind hole. The atomization cavity 202 is communicated with the air suction cavity 102, and the oil storage cavity 30 is communicated with the atomization cavity 202 through the oil inlet hole 204. The heating assembly 21 is installed in the atomization cavity 202, and the heating assembly 21 is located at the oil inlet hole 204.
[0044] The sealing oil component 25 is located at one end of the oil injection hole 206 (i.e., the bottom wall of the oil injection hole 206) and can be penetrated by the oil injection device. The oil injection device pierces the bottom wall of the oil injection hole 206 and extends into the oil storage cavity 30 to inject oil into the oil storage cavity 30. After the oil injection operation is completed, the oil injection device is pulled out from the oil injection hole 206. The penetration hole formed by piercing can be reset and seal the oil storage cavity 30. The inserted sealing part 23 is inserted into the oil injection hole 206 from the opposite end of the oil injection hole 206 and blocks the oil injection hole 206.
[0045] With the above structure, during the assembly process of the atomization host 100, first, the atomization component 20 is installed into the sealing oil component 25 to block the oil storage cavity 30. Then, the oil injection device is inserted into the oil injection hole 206 and pierces the sealing oil component 25 to inject e-liquid into the oil storage cavity 30, making it easier for the oil injection device to inject e-liquid into the oil storage cavity 30, and thus making it easier to produce the atomization host 100.
[0046] After the oil injection device is pulled out, the penetration hole formed by piercing can be reset and seal the oil storage cavity 30. Then, the inserted sealing part 23 is inserted into the oil injection hole 206. The inserted sealing part 23 blocks the oil injection hole 206, which can further prevent the e-liquid in the oil storage cavity 30 from leaking. Thus, while it is easy to inject e-liquid into the atomization host 100, the tightness of the oil storage cavity 30 is improved.
[0047] Specifically, in this embodiment, an air suction cavity 102 is formed at one end of the mouthpiece 10, and an oil storage cavity 30 is provided at the other end; one end of the oil storage cavity 30 away from the air suction cavity 102 is an opening, and the sealing oil component 25 seals the opening of the oil storage cavity 30. In other embodiments, the oil storage cavity 30 can also be formed between the mouthpiece 10 and the atomization component 20.
[0048] In this embodiment, the air suction cavity 102 is formed on the side of the mouthpiece 10 facing away from the atomization component 20. The sealing oil component 25 is made of silica gel material; under its own elastic action, after the oil injection device is pulled out, the penetration hole formed by piercing the oil injection device can close itself, so that the oil storage cavity 30 is sealed again.
[0049] The inserted sealing part 23 has a structure similar to a cylinder. One end of the inserted sealing part 23 is inserted into the oil injection hole 206, and the side surface of the inserted sealing part 23 abuts against the hole wall of the oil injection hole 206. Thus, the inserted sealing part 23 can play a role in secondary sealing of the oil injection hole 206, improving the tightness of the atomization host 100 after oil injection and further preventing the e-liquid in the oil storage cavity 30 from leaking.
[0050] In other embodiments, the inserted sealing part 23 can also be of other structures, such as a cuboid block structure; the inserted sealing part 23 can be in contact with the bottom wall of the oil injection hole 206, or there can be a gap between the inserted sealing part 23 and the bottom wall of the oil injection hole 206.
[0051] Please refer to Figure 4 and Figure 5 , in some embodiments, an annular protrusion 24 is provided on the hole wall of the fuel injection hole 206. The annular protrusion 24 abuts against the inserted oil sealing part 23, and the annular protrusion 24 seals the gap between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206.
[0052] With the above structure, the annular protrusion 24 abuts against the inserted oil sealing part 23, and the annular protrusion 24 seals the gap between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206; under the action of the annular protrusion 24, a gap can exist between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206. Thus, even if part of the e-liquid penetrates through the oil sealing component 25 and seeps into the fuel injection hole 206, the inserted oil sealing part 23 will prevent the e-liquid from flowing out of the fuel inlet hole 204, and the seeped e-liquid can be stored in the gap between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206, ultimately reducing the possibility of the e-liquid flowing out of the fuel injection hole 206 through the oil sealing component 25.
[0053] Specifically, the annular protrusion 24 is made of silica gel material, and the annular protrusion 24 is integrally formed with the oil sealing component 25. In this embodiment, the annular protrusion 24 is in a circular ring shape, and the cross-section of the annular protrusion 24 is semi-circular. In other embodiments, the annular protrusion 24 can also be in other shapes adapted to the side wall of the fuel injection hole 206, such as a frame shape; the cross-section of the annular protrusion 24 can also be in other shapes, such as a rectangle.
[0054] In other embodiments, the annular protrusion 24 can also be provided on the outer surface of the inserted oil sealing part 23, so that when the inserted oil sealing part 23 is inserted into the fuel injection hole 206, the annular protrusion 24 abuts against the inner wall of the fuel injection hole 206, thereby sealing the gap between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206.
[0055] In some embodiments, the central axis of the annular protrusion 24, the central axis of the fuel injection hole 206, and the central axis of the inserted oil sealing part 23 are collinear. The number of the annular protrusions 24 is multiple, and in the direction from the fuel injection hole 206 to the oil storage cavity 30, all the annular protrusions 24 are arranged in a row.
[0056] With the above structure, the central axis of the annular protrusion 24, the central axis of the fuel injection hole 206, and the central axis of the inserted oil sealing part 23 are collinear; thus, after the fuel injection is completed, the inserted oil sealing part 23 is more easily inserted into the fuel injection hole 206, making the assembly of the atomization main unit 100 more convenient; in addition, multiple annular protrusions 24 can achieve a better sealing effect on the gap between the inserted oil sealing part 23 and the hole wall of the fuel injection hole 206; when multiple annular protrusions 24 are arranged in a row, the oil sealing component 25 is more easily formed as a whole.
[0057] Specifically, in this embodiment, the number of the annular protrusions 24 is three. In other embodiments, the number of the annular protrusions 24 may also be other numbers, such as two or four.
[0058] In some embodiments, the oil sealing component 25 includes a main body 252 and an elastic oil sealing part 253 which are connected to each other. The elastic oil sealing part 253 is inserted into the oil storage cavity 30 and abuts against the cavity wall of the oil storage cavity 30; the elastic oil sealing part 253 can be penetrated by an oil injection device, and after the oil injection device is pulled out from the oil injection hole 206, the elastic oil sealing part 253 can reset and seal the oil storage cavity 30. There is a gap between the elastic oil sealing part 253 and the inserted oil sealing part 23 (that is, the gap between the top end of the inserted oil sealing part 23 and the bottom wall of the oil injection hole 206).
[0059] With the above structure, on the one hand, there is a buffer space between the elastic oil sealing part 253 and the inserted oil sealing part 23, and the inserted oil sealing part 23 will not contact and press the elastic oil sealing part 253. Furthermore, after the oil injection is completed, the elastic oil sealing part 253 will not deform, so as to avoid the leakage of the e-liquid in the oil storage cavity 30 during the assembly process of the atomization main unit 100.
[0060] On the other hand, the gap between the elastic oil sealing part 253 and the inserted oil sealing part 23 can store a small amount of e-liquid. Even if part of the e-liquid oozes out through the elastic oil sealing part 253, the gap between the elastic oil sealing part 253 and the inserted oil sealing part 23 can also play a buffering role for the oozed e-liquid.
[0061] Specifically, in this embodiment, the oil injection hole 206 includes a first section 2062 and a second section 2064 which are coaxially arranged. The aperture of the first section 2062 is smaller than that of the second section 2064. The first section 2062 is closer to the oil storage cavity 30 than the second section 2064. The elastic oil sealing part 253 is connected to the hole wall at the first section 2062, the annular protrusion 24 is connected to the hole wall at the second section 2064, and the inserted oil sealing part 23 extends into the second section 2064. In other embodiments, the oil injection hole 206 may also have other structures, such as a cylinder.
[0062] Please refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , in some embodiments, the atomization main unit 100 further includes a mounting bracket 26, an air duct 27 and a housing 28. The mounting bracket 26 is mounted on the oil sealing component 25, and the housing 28 is sleeved on the mouthpiece 10, the oil sealing component 25 and the mounting bracket 26 (see Figure 2 ).
[0063] The nozzle 10 is provided with an oil storage cavity 30. The air duct 27 is located inside the oil storage cavity 30. The air duct 27 includes a first end 272 and a second end 274. The first end 272 is installed on the nozzle 10, and the second end 274 is installed on the oil sealing component 25. An atomization cavity 202 is arranged inside the air duct 27, and the heating component 21 is located in the atomization cavity 202. An oil inlet hole 204 is arranged on the outer wall of the air duct 27. The e-liquid in the oil storage cavity 30 is transmitted to the heating component 21 through the oil inlet hole 204. The inserted oil sealing part 23 and the mounting bracket 26 are integrally formed (during the production process, the inserted oil sealing part 23 and the mounting bracket 26 are manufactured by the same production equipment at the same time).
[0064] With the above structure, during the assembly process of the atomization main unit 100, first, the heating component 21 is assembled into the air duct 27, and the second end 274 of the air duct 27 is fixed on the oil sealing component 25. Then, the fixed air duct 27 and the oil sealing component 25 are inserted into the oil storage cavity 30, and the first end 272 of the air duct 27 is inserted and fixed to the nozzle 10. At the same time, the oil sealing component 25 seals the opening of the oil storage cavity 30. So that the nozzle 10, the oil sealing component 25 and the air duct 27 are connected to each other, and the air duct 27 is placed inside the oil storage cavity 30. The suction cavity 102 is communicated with the atomization cavity 202 through the first end 272 of the air duct 27.
[0065] Subsequently, the outer shell 28 is sleeved on the connection part of the nozzle 10 and the oil sealing component 25. Then, the oil injection device passes through the oil injection hole 206, pierces the elastic oil sealing part 253, and the oil injection device injects e-liquid into the oil storage cavity 30. After the oil injection is completed, the pierced hole at the elastic oil sealing part 253 resets under its own elastic force and seals the pierced hole. The mounting bracket 26 is installed on the oil sealing component 25, so that the inserted oil sealing part 23 is inserted into the oil injection hole 206 and further plugs and seals the oil injection hole 206. Thus, the assembly process of the atomization main unit 100 is very convenient and there will be no oil leakage.
[0066] At the same time, the inserted oil sealing part 23 and the mounting bracket 26 are integrally formed, reducing the number of components and the assembly steps. During the assembly process, the inserted oil sealing part 23 also plays a role in positioning and fixing the mounting bracket 26, so that no additional fixing structure is required between the mounting bracket 26 and the oil sealing component 25, and it is easy to install.
[0067] Specifically, in this embodiment, the oil sealing component 25 is snap-fitted to the nozzle 10, and the outer shell 28 is also snap-fitted to the oil sealing component 25, so that the oil sealing component 25, the nozzle 10 and the outer shell 28 can be tightly connected. The first end 272 is inserted into the nozzle 10, and the second end 274 is inserted into the oil sealing component 25. The oil inlet hole 204 is a circular through hole, and the oil inlet hole 204 is opened on the pipe wall of the air duct 27. The inserted oil sealing part 23 protrudes from one end face of the mounting bracket 26.
[0068] In other embodiments, the oil sealing member 25 and the nozzle 10 can also be connected in other ways, such as by adhesion; the housing 28 and the oil sealing member 25 can also be connected in other ways, such as by interference fit; the oil inlet hole 204 can be of other shapes, such as kidney-shaped or diamond-shaped.
[0069] In some embodiments, the air guide tube 27 includes a thick tube section 276 and a thin tube section 278 that are connected to each other. The first end 272 is located at one end of the thin tube section 278 away from the thick tube section 276, and the second end 274 is located at one end of the thick tube section 276 away from the thin tube section 278. The atomization chamber 202 and the oil inlet hole 204 are both opened in the thick tube section 276. The nozzle 10 assembly includes an annular wall 12. The annular wall 12 extends into the oil storage chamber 30, and the first end 272 is inserted into the annular wall 12. The inner surface of the annular wall 12 abuts against the outer surface of the thin tube section 278.
[0070] With the above structure, the atomization chamber 202 is opened in the thick tube section 276 so that the atomization chamber 202 can have a larger volume. Thus, within the same time, a larger amount of e-liquid can be atomized in the atomization chamber 202. In addition, the annular wall 12 is used for the first end 272 to be inserted, and the outer surface of the thin tube section 278 abuts against the inner surface of the annular wall 12 to separate the oil storage chamber 30 from the internal space of the air guide tube 27, so as to prevent the e-liquid from flowing into the atomization chamber 202 through the connection between the first end 272 and the nozzle 10.
[0071] Specifically, the annular wall 12 is circular, and there is an interference fit between the annular wall 12 and the thin tube section 278. The thick tube section 276 and the thin tube section 278 are connected by a tube section similar to a frustum of a cone so that the entire air guide tube 27 can be integrally formed.
[0072] In some embodiments, four mounting cavities 2504 are opened at one end of the oil sealing member 25 away from the nozzle 10. The four mounting cavities 2504 are respectively located at the four corners of the oil sealing member 25, and the mounting cavities 2504 are cylinders; an electrical connector 29 is provided in the mounting cavities 2504; the electrical connector 29 is electrically connected between the heating component 21 and the power source so that the power source can supply power to the heating component 21. The number of the second air inlet holes 2602 is also four, and each second air inlet hole 2602 corresponds to one mounting cavity 2504, and the first air inlet hole 2502 is offset from the second air inlet hole 2602.
[0073] A groove 2505 is also opened on one end of the oil sealing member 25 away from the nozzle 10. There is a groove 2505 between the mounting cavity 2504 and the first air inlet hole 2502 on the same side.
