Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette with a simple assembly process and good atomization effect. Background Art
[0002] The atomizer core structure of existing atomizers often uses layers of cotton cloth wrapped around a ceramic heating element, which is then inserted into the atomizer sleeve. The electronic atomizer liquid is fed into the oil hole in the center of the atomizer sleeve. The cotton rolling process is often done manually, with uncontrollable force, which can easily lead to inconsistent overall outer diameter dimensions after wrapping. After rolling, the outer diameter of the cotton body is larger, making it difficult to insert into the atomizer sleeve. After rolling, the outer diameter of the cotton body is smaller, which can cause leakage. In addition, the electrical connections of the power supply circuit of existing e-cigarettes are often made by welding, which is a complex welding process and prone to the risk of false welding and poor solder joints.

[0032] See also Figures 1 to 9 This embodiment provides an electronic cigarette, which includes an atomizer 100 and a battery rod assembly 200 , wherein the battery rod assembly 200 supplies power to the atomizer 100 .
[0033] First, see Figures 2 to 6 , the structure of the atomizer 100 is introduced in detail. The atomizer 100 includes: a first tube body 11, an atomizing liquid tube body 12 sleeved on the inner wall of the first tube body 11, wherein the length of the atomizing liquid tube body 12 is slightly smaller than the length of the first tube body 11, a suction nozzle 13 is fixed on the upper end of the first tube body 11, and the bottom of the suction nozzle 13 is connected to the ventilation pipe 14, which is located inside the first tube body 11. The bottom of the suction nozzle 13 is also provided with oil-absorbing cotton, and the other end of the ventilation pipe 14 is connected to the atomizer core assembly 10 of the atomizer, and a first connector 19 is fixed on the lower end of the first tube body 11. The first connector 19 is electrically connected to the negative electrode of the atomizer core assembly 10 of the atomizer 100. A conductive column 18 is also provided in the middle of the lower connecting seat 17, and the conductive column 18 is electrically connected to the positive electrode of the atomizer core assembly 10 of the atomizer 100.
[0034] Please refer again to Figure 3 The atomizer core assembly 10 of the atomizer 100 includes: an atomizer core 16, an upper connecting seat 15 connected to the upper end of the atomizer core 16, and a lower connecting seat 17 connected to the lower end of the atomizer core 16. In this embodiment, the upper connecting seat 15 and the lower connecting seat 17 are both made of silicone.
[0035] Please refer again Figure 8 The atomizer core 16 includes: an electric heating element 160, and an oil-conducting medium 163 surrounding the outer wall of the electric heating element 160. The oil-conducting medium 163 is composed of several layers of oil-conducting layers with through holes in the middle. The oil-conducting layers are sleeved on the outer wall of the electric heating element 160 through the through holes in the middle. When the electric heating element 160 is powered on and heated, the oil-conducting medium evenly supplies the atomized liquid to the electric heating element, atomizing the atomized liquid in the electric heating element. Please combine again Figure 5The upper end surface of the oil-guiding medium 163 is attached to the upper connecting seat 15, and the lower end surface is attached to the lower connecting seat 17. The outer wall of the oil-guiding medium 163 is attached to the inner wall of the atomizing liquid tube body 12. At the same time, the outer walls of the upper connecting seat 15 and the lower connecting seat 17 are in contact with the inner wall of the atomizing liquid tube body 12.
[0036] Specifically, the electric heating element 160 includes a ceramic component 161 and a heating wire 162 embedded in the ceramic component 161 . A through cavity 1611 is provided in the middle of the ceramic component 161 .
[0037] In this embodiment, the ceramic member 161 is a cylindrical ceramic having the through cavity 1611 defined in the middle thereof. The heating wire 162 is a spiral heating wire embedded in the sidewall of the cylindrical ceramic. Both the positive and negative ends of the spiral heating wire extend from the surface of the cylindrical ceramic. The positive end is electrically connected to the conductive post 18, and the negative end is electrically connected to the first connector 19. In other embodiments, the ceramic member 161 may be of any shape, such as a cube or a cone, and the corresponding heating wire 162 may also be of any shape.
[0038] Preferably, the oil-conducting layer of the oil-conducting medium 163 is an oil-conducting cotton sheet. The oil-conducting cotton sheet is circular, oval, or square, with a through-hole in the center. During assembly, the oil-conducting cotton sheets simply need to be stacked and placed on the outer wall of the cylindrical ceramic. This provides simple operation, stable process, uniform thickness, and even infiltration of the atomized liquid, thereby improving the atomization effect. In other embodiments, the oil-conducting layer can also be made of materials such as fiber and ceramic.
[0039] Please refer again Figure 7 The upper connector 15 includes a tapered portion 151 and a tubular body 152 extending from the upper end of the tapered portion 151. A communicating atomization hole 153 is formed in the middle of the tapered portion 151 and the tubular body 152. The tapered portion 152 is also provided with a plurality of longitudinal liquid holes 1511. The atomization hole 153 and the liquid holes 1511 can be circular, square, or any other shape, with no particular diameter. The vent tube 14 is inserted into the tubular body 152.
[0040] Please refer again Figure 2 and Figure 5 The annular cavity formed between the exterior of the vent tube 14 and the atomized liquid pipe body 12 serves as a liquid storage chamber for storing atomized liquid during use. This liquid storage chamber is connected to a liquid through-hole 1511 on the upper connecting seat 15, through which the atomized liquid flows to the oil-conducting medium 163. The upper connecting seat 15 and the lower connecting seat 17 are both fixed within the atomized liquid pipe body 12, and the atomizer core 16 of the atomizer 100 is located between the upper connecting seat 15 and the lower connecting seat 17.
[0041] Please refer again Figure 2 and Figure 6 , the battery rod assembly 200 includes a second connector 20 that is screwed to the first connector 19. The first connector 19 is provided with an internal thread, and the second connector 20 is provided with an external thread, and the two are screwed together by threads. In other embodiments, the two can also be connected by magnetic attraction, snap-on connection or other methods. The second connector 20 is clamped on the outside of the second tube body 21, and a battery 22 is provided in the second tube body 21. The lower end of the battery 22 is provided with a microphone switch group fixing sleeve 23. The second tube body 21 is also provided with a microphone switch assembly 24. A light guide seat 26 is provided below the microphone switch assembly 24. A charging connector is provided in the light guide seat 26. Specifically, the charging connector includes a charging positive pole 28 and a charging negative pole ring 27 fixed in the light guide seat 26. The charging positive pole 28 is electrically connected to the microphone switch assembly 24, and the charging negative pole ring 27 is electrically connected to the negative pole of the battery 22. As Figure 6 As shown, the light guide base 26 is provided with a post hole for securing the positive charging pole 28 and an annular groove for the negative conductive ring 27. The microphone switch assembly 24 is connected to the positive charging pole 28 via a wire 25. Specifically, one end of the wire 25 is electrically connected to the microphone switch assembly 24, while the other end extends and bends at the bottom of the post hole. When the positive charging pole 28 is inserted into the post hole, it is crimped onto the end of the wire 25, thereby achieving electrical contact between the two. This electrical connection method differs from welding and other methods used in the prior art, making assembly simpler and avoiding potential welding hazards such as false solder joints. The second tube body 21 is connected to the negative charging pole ring 27 and electrically conductive. The second tube body 21 is also electrically conductive to the second connector 20. The positive electrode of the battery is also electrically connected to the conductive pole 18. Therefore, when the first connector 19 is connected to the second connector 20, the battery 22 forms a switch control circuit with the electric heater 160 through the microphone switch assembly 24 to control whether the electric heater 160 is powered on or off. When the user inhales from the mouthpiece 13 , the microphone switch assembly 24 turns on the circuit of the electric heater 160 , causing the electric heater 160 to heat up and atomize the atomized liquid. The atomized smoke is then output from the mouthpiece 13 to the user through the vent pipe 14 .
[0042] See also Figure 9 The light guide base 26 includes a tubular body 261. A positive electrode fixing post 263 is axially disposed within the tubular body 261. The positive electrode fixing post 263 is provided with a fixing hole 266. The bottom end of the positive electrode fixing post 263 is connected to the inner wall of the tubular body 261 via a plurality of connecting ribs 264. An annular groove 265 is formed between the positive electrode fixing post 263 and the tubular body 261. The negative electrode terminal 27 is fixed in the annular groove 265. The lower end surface of the tubular body 261 forms an annular light-guiding surface 262 for displaying the operating status of the microphone switch assembly 24, that is, the operating status of the electronic cigarette.
[0043] like Figure 6As shown, the negative terminal 27 includes: a tubular portion 271, and a plug-in portion 272 extending outward from the outer wall of the tubular portion 271. The tubular body 261 of the light guide seat 26 is provided with a plug-in hole 267 corresponding to the plug-in portion 272. The negative terminal 27 is inserted into the plug-in hole 267 through the plug-in portion 272 to make electrical contact with the tube body 21 without welding, thereby forming an electrical connection with the negative pole of the battery 22.
[0044] Among them, a wire hole 268 is also provided at the bottom of the fixing hole 266. The wire 25 is passed through the wire hole 268 to form a bent portion. After the positive terminal 28 is installed in the fixing hole 266, the bent portion is pressed and fixed to the bottom of the fixing hole 266, thereby realizing a solder-free electrical connection between the positive terminal 28 and the microphone switch assembly 24.
[0045] Compared to existing technologies, the electronic cigarette of this embodiment improves upon the existing method of wrapping a ceramic core with layers of cotton to a multi-layered structure of oil-conducting cotton sheets. This effectively solves the problems of uneven thickness of the oil-conducting medium, inconvenient assembly, and poor atomization caused by manually rolling the cotton. Furthermore, the electronic cigarette further connects the positive and negative charging poles to the leads leading from the positive and negative electrodes of the battery through a clamping connection with the light guide base, effectively eliminating the hidden dangers of false and poor solder joints caused by existing welding processes. This makes product assembly and subsequent maintenance more convenient.
