Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to an electronic cigarette atomizer and an electronic cigarette. Background Technology

[0002] Currently, some electronic cigarettes on the market use ceramic atomizing cores (hereinafter referred to as ceramic cores). The ceramic cores have microporous structures to allow the atomizing liquid to pass through. By heating the ceramic cores, the atomizing liquid can be atomized for users to inhale.

[0003] Patent No. 201420266716.1 discloses an atomizer for electronic cigarettes and an electronic cigarette. The ceramic core is cylindrical in shape and the internal atomization channel is conical. This results in uneven wall thickness of the ceramic core on the outside of the atomization channel. The thicker the part, the worse the oil conductivity. The uneven oil conductivity of the ceramic core also results in uneven heating speed of the ceramic core, leading to uneven atomization effect. Utility Model Content

[0043] Specifically, the atomizing liquid cup 1 is used to hold the atomizing liquid, and the atomizing core assembly 2 is located below to seal the liquid chamber 11. The atomizing liquid is placed in the liquid chamber 11 and passes through the ceramic core 21. The heating element 221 heats the ceramic core 21, causing the atomizing liquid to be atomized into an aerosol in the atomization channel 211. The user inhales the vapor through the air tube 12. The ceramic core 21 is generally shaped with inner and outer double cone surfaces. The ceramic core 21 has a uniform thickness and high oil conductivity, which facilitates the rapid and uniform heating of the ceramic core 21 to atomize the atomizing liquid.

[0044] It should be noted that the heating element 221 is attached to the surface of the atomizing channel 211. Under the same projected area, the heating area of ​​the atomizing core assembly 2 is larger, which makes the ceramic core 21 heat up faster and atomize quickly, thus improving the user experience. In addition, the conical structure makes it easier to observe the setting of the heating element 221 with the naked eye and makes it easier to control product quality.

[0045] Furthermore, in some embodiments, the atomizing channel 211 further includes a flat hole section 2112, which is located above the conical hole section 2111 and is connected to the air pipe 12; the outer wall of the flat hole section 2112 is cylindrical; and the upper end surface of the ceramic core 21 is planar.

[0046] Specifically, the outer wall of the flat hole section 2112 is cylindrical; the upper end surface of the ceramic core 21 is flat, which makes it easier to seal the upper end of the ceramic core 21.

[0049] In some embodiments, a sealing groove is provided around the base support 232, and a sealing silicone 236 is provided in the sealing groove to seal the base support 232 and the atomizing liquid cup 1; a sealing frame silicone 235 is provided on the sealing support 231, which seals the sealing support 231 and the atomizing liquid cup 1, and a through hole 2351 is provided on the sealing frame silicone 235 to connect the leakage hole 2311 and the liquid tank 11.

[0050] Furthermore, in some embodiments, the base support 232 is provided with an air hole 2322 communicating with the conical hole section 2111 and a conical protrusion 2321 inserted into the conical hole section 2111; a gas flow cavity is formed between the outer wall of the conical protrusion 2321 and the inner wall of the conical hole section 2111.

[0051] Specifically, the air vent 2322, the gas flow chamber, and the air tube 12 form the air path of the electronic smoke atomizer; compared with the natural air path, the gas flow in the gas flow chamber flows more evenly over the atomizing surface, which can better collect smoke and improve the heat dissipation efficiency of the atomizing surface.

[0052] Furthermore, in some embodiments, the outer wall of the conical protrusion 2321 is parallel to the inner wall of the conical hole section 2111, so that the gas flow cavity is a smooth cavity; multiple air holes 2322 are provided, and the air holes 2322 are evenly distributed along the lower end of the gas flow cavity.

[0053] Specifically, the gas flow chamber is a smooth cavity, and the air holes 2322 are evenly distributed along the lower end of the gas flow chamber, which can make the gas flow more evenly in the gas flow chamber and can more evenly collect the atomized smoke.

[0057] Specifically, the positioning blind hole 2323 not only reduces the material required for the base bracket 232, but also serves to guide the installation of the electronic cigarette atomizer during installation and use; the guiding slope makes it easier for the protrusion to be inserted into the positioning blind hole 2323; in some embodiments, the upper end of the positioning blind hole 2323 is located in the conical protrusion 2321.

[0058] Furthermore, in some embodiments, the heating element 221 includes a contact 2211 and a heating area 2212, with the contact 2211 located at the bottom of the ceramic core 21 and the heating area 2212 located on the surface of the tapered hole section 2111.

[0059] Specifically, contact 2211 is used to electrically connect with conductive electrode 222. In some embodiments, conductive electrode 222 abuts against contact 2211. Heating area 2212 is curved, which can control the spatial distribution of temperature field on atomized surface and achieve better heating effect.

[0060] Furthermore, in some embodiments, the heating zone 2212 is provided with one or more; the heating zone 2212 is installed on the surface of the tapered hole section 2111 using an embedded metal mesh process or a thick film printing process.

[0061] Specifically, in some embodiments, multiple heating zones 2212 can be connected in parallel or in series; the conical design of the atomization channel 211 of the ceramic core 21 makes it easier to implement the embedded metal mesh process and thick film printing process, making it easier to connect the ceramic core 21 and the heating component 22.

The atomizing core assembly 2 is located below and encloses the liquid chamber 11. The atomizing liquid is placed in the liquid chamber 11 and passes through the ceramic core 21.
