Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and more specifically, to an electronic cigarette atomizer. Background Art

[0002] The existing atomizer core mainly includes porous ceramics and heating wires. The heating wire in the ceramic atomizer core heats the smoke liquid to achieve atomization. The prior art discloses that a temperature sensor is used to detect the heating temperature of the heating wire, and a control unit controls the heating power of the heating wire through a temperature signal transmitted by the temperature sensor, so that the heating power of the heating wire is within a control threshold range, thereby achieving control and regulation of the heating temperature of the heating wire.

[0003] This method relies on the sensitivity of the temperature sensor. If the atomization temperature is slightly higher by 10-50℃, the atomization effect will be greatly affected, especially for users who are sensitive to the smell of atomization. Improving the sensitivity of the temperature sensor will undoubtedly increase the production cost of e-cigarettes. E-cigarette products themselves are fast-moving consumer goods, which reduces the profit margin for manufacturers.

[0004] On the other hand, the heating wire is a linear heating method, so a temperature transfer process is bound to occur. When the heating temperature of the heating wire is too high, the local temperature is too high, and the surrounding temperature may not reach the atomization temperature requirement, so the atomization effect is not good.

[0008] Preferably, a liquid guiding hole is provided on the side wall of the liquid guiding tube on the side of the groove.

[0009] Preferably, the liquid guiding hole is a rectangular structure.

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0047] The utility model provides an electronic cigarette 10, see Figure 1 The electronic cigarette 10 includes a first shell 11 and a second shell 12 connected to the first shell 11. The first shell 11 and the second shell 12 form a containing space for accommodating a cigarette cartridge unit and a control unit. The first shell 11 and the second shell 12 have a front end 110 and a rear end 120 along the longitudinal x direction. The front end 110 is provided with an air outlet, which is connected to the suction nozzle 13. The rear end 120 is provided with an air inlet. It can be known that the first shell 11 and the second shell 12 can be an integrally formed structure.

[0048] The cartridge unit includes a liquid storage tube, liquid storage cotton, an atomizer tube 14 and an atomizer 20. The liquid storage tube is provided with liquid storage cotton for storing smoke liquid or smoke oil. The smoke liquid in the liquid storage cotton penetrates into the atomizer 20. Under the heating condition of the atomizer, the smoke liquid is atomized and enters the suction nozzle 13 through the atomizer tube 14.

[0049] For details, see Figure 2 , Figure 3 and Figure 4 The atomizing tube 14 is a cylindrical structure, one end of which is connected to the suction nozzle 13, and the other end is connected to the atomizer 20. The atomizing tube 14 and the atomizer 20 are arranged on the liquid storage cotton ( Figure 2In the middle dotted frame), the material of the atomizer tube 14 is selected from one of stainless steel, ceramic, and glass fiber, which has the functions of anti-corrosion and anti-adhesion of smoke oil.

[0050] like Figure 5 As shown, the atomizer 20 includes a liquid guiding tube 21 , a liquid guiding medium 22 is arranged in the liquid guiding tube 21 , a heating unit 23 is arranged inside the liquid guiding medium 22 , and a sealing head 24 is also arranged in the liquid guiding tube 21 .

[0051] For example, see Figure 6-Figure 9 The liquid guide tube 21 has a front port 211 and a rear port 212. The outer diameter of the liquid guide tube 21 is slightly smaller than the inner diameter of the atomizing tube 14. Figure 4 As shown, the atomizer tube 14 can be sleeved on the outside of the liquid guide tube 21 in the atomizer 20. Preferably, the atomizer tube 14 and the liquid guide tube 21 are tightly matched. It can be understood that the gap between the atomizer tube 14 and the liquid guide tube 21 is as small as possible to prevent the smoke liquid in the atomizer 20 from being discharged through the gap after being atomized. At the same time, it is prevented that the smoke liquid in the liquid storage cotton enters the atomizer tube 14 through the gap to affect the atomized taste.

[0052] The front end 211 of the liquid guide tube 21 is provided with a groove 2111, and the groove 2111 extends along the axial direction of the liquid guide tube 21. Preferably, the length of the groove 2111 extending along the axial direction of the liquid guide tube 21 is 2 / 3 of the axial length of the liquid guide tube 21, and more preferably, it is 4 / 5 of the axial length of the liquid guide tube 21. When the axial length of the groove 2111 along the liquid guide tube 21 is large, the machining accuracy of the outer diameter of the liquid guide tube 21 can be reduced. In one embodiment, the outer diameter of the liquid guide tube 21 is slightly larger than the inner diameter of the atomizer tube 14, and the liquid guide tube 21 can be tightly matched with the atomizer tube 14 except for the groove 2111 by squeezing the front end 211 of the liquid guide tube 21.

[0053] The groove 2111 is used to accommodate the liquid guiding medium 22 , and a liquid guiding hole 2122 is provided on the side wall of the liquid guiding tube 21 on the side of the groove 2111 , so that the smoke liquid in the liquid storage cotton can penetrate into the liquid guiding medium 22 in the liquid guiding tube 21 through the liquid guiding hole 2122 .

[0054] In the above embodiment, the liquid guide hole 2122 extends axially along the liquid guide tube 21 to form a rectangular window structure. Figure 6 As shown, the liquid guiding holes 2122 are arranged at intervals along the circumference of the liquid guiding tube 21 , which is conducive to the penetration of smoke liquid into the liquid guiding medium 22 in the liquid guiding tube 21 .

[0055] In one embodiment, the liquid guide hole 2123 is configured as a square or small rectangular window structure, such as Figure 7As shown, the liquid guide holes 2123 are arranged at intervals along the circumference of the liquid guide tube 21. For smoke liquids with different densities, the smaller liquid guide holes 2123 effectively prevent excessive smoke liquid from penetrating into the liquid guide medium 22 in the liquid guide tube 21, causing "oil explosion" or "oil leakage".

[0056] In one embodiment, the liquid guide hole 2124 is configured as a circular hole. Figure 8 As shown, the liquid guide holes 2124 are arranged at intervals along the circumference of the liquid guide tube 21. Similarly, the smaller liquid guide holes 2124 effectively prevent excessive smoke liquid from penetrating into the liquid guide medium 22 in the liquid guide tube 21, causing "oil explosion" or "oil leakage".

[0057] In one embodiment, the liquid guide hole 2125 is configured to have an arc groove, such as Fig. 9 As shown, the liquid guide hole 2125 has an inclined angle. When the smoke liquid in the liquid storage cotton decreases, the smoke liquid can gradually accumulate along the liquid guide hole 2125 and finally penetrate into the liquid guide medium 22 in the liquid guide tube 21.

[0058] The liquid-conducting medium 22 contained in the liquid-conducting tube 21 includes a medium body 221 and a protruding portion 222. Fig.10 As shown, the medium body 221 is cylindrical, and a protrusion 222 is provided along the generatrix of the medium body 221. The outer diameter of the medium body 221 matches the inner diameter of the liquid guide tube 21, and the protrusion 222 matches the groove 2111 of the liquid guide tube 21. The protrusion 222 protrudes outward, and when the atomizing tube 14 is sleeved with the liquid guide tube 21, the end of the atomizing tube 14 abuts against the top of the protrusion 222 ( Figure 4 ). The material of the liquid conducting medium 22 is selected from one of ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, and PET fiber.

[0059] In one embodiment, the medium body 221 in the liquid-conducting medium 22 is symmetrically provided with a protrusion 222 and a protrusion 222a ( Fig.11 ), it can be known that the front port 211 of the corresponding liquid guide tube 21 symmetrically opens the groove 2111 and the groove 2111a ( Fig.12 ), the liquid guiding medium 22 is inserted into the liquid guiding tube 21, the medium body 221 is accommodated in the liquid guiding tube 21, the protrusion 222 matches the groove 2111, and the protrusion 222a matches the groove 2111a ( Fig.13 ).

[0060] The protrusion 222 and the protrusion 222a in the above embodiment extend outward (toward the liquid storage cotton), and the medium body 221 at the liquid guide hole 2122 can contact the liquid storage cotton. The tobacco oil in the liquid storage cotton can penetrate through the protrusion 222 (222a) and the liquid guide hole 2122 to the medium body 221 of the liquid guide medium 22.

[0061] It should be noted that in the above embodiment, the medium body 221 extends axially along the liquid guide tube 21. Specifically, the medium body 221 extends a certain distance along both ends of the axial direction of the liquid guide tube 21 and completely blocks the liquid guide hole 2122. More specifically, the medium body 221 can completely cover the liquid guide hole 2122 to prevent the smoke oil in the liquid storage cotton from penetrating into the atomization tube 14.

[0062] In other embodiments, see Fig.14 The raised portion 222 in the liquid-conducting medium 22 is arranged in the middle area of ​​the medium body 221. Specifically, the top of the raised portion 222 is at a certain distance from the top of the medium body 221, and the bottom of the raised portion 222 is at a certain distance from the bottom of the medium body 221. The medium body 221 can be filled into the liquid-conducting tube 21, and the atomizing tube 14 is sleeved with the liquid-conducting tube 21. At the same time, the atomizing tube 14 abuts against the top of the raised portion 222, and the medium body 221 is inserted into the atomizing tube 14 for a certain distance, which effectively solves the problem that the e-liquid in the liquid storage cotton penetrates into the atomizing tube 14 through the gap at the abutment or the gap at the liquid-conducting hole 2122.

[0063] The liquid-conducting medium 22 in the above embodiment has a central through hole for arranging the heating unit 23 , and the smoke liquid enters the atomizing tube 14 through the through hole after being atomized.

[0064] The heating unit 23 disposed in the liquid-conducting medium 22 includes a heating body 231 and electrodes 231a and 231b disposed on the heating body 231. Fig.15 As shown, the heating body 231 is an arc surface, and the two ends of one side of the arc surface are respectively connected to the electrode 231a and the electrode 232b, and the other ends of the electrode 231a and the electrode 232b are electrically connected to the control unit, and the heating unit 23 is powered by the control unit. The heating body 231 is an arc surface, and the heating source is a surface heating source. The smoke liquid is evenly heated on the surface of the heating body 231 to avoid a large temperature gradient.

[0065] In one embodiment, the heating body 231 is provided with a guide groove 232 along an arc. Fig.15 ), the guide groove 232 may be provided in plurality, and spaced apart along the axial direction of the liquid guiding tube 21 ( Fig.16 ), the guide groove 232 ensures that the smoke liquid that penetrates into the liquid-conducting medium 22 can be atomized through the guide groove 232 and the atomized smoke liquid enters the atomization tube 14 through the guide groove 232.

[0066] The sealing head 24 is disposed at the rear end port 212 of the liquid guiding tube 21 and is used to fix the heating unit 23 and the electrodes 231a and 231b of the heating unit 23. Fig.17The sealing head 24 has a central through hole 241 for passing the electrode 231a and the electrode 231b; the front end of the sealing head 24 is provided with a chamfer 242 to facilitate insertion into the tail port 212 of the catheter 21; the sealing head 24 has a straight section 243, and the straight section 243 is provided with a circular groove 244 along the circumferential direction, see Fig.18 The straight section 243 of the sealing head 24 contacts the inner wall of the liquid guiding tube 21 , and a small air gap exists between the central through hole 241 of the sealing head 24 and the circular groove 244 on the straight section 243 for air to enter.

[0067] The atomization effect of the electronic cigarette atomizer determines the quality of the electronics. The structure in the present application can solve the problem of uneven heating of the heating wire in the traditional atomizer, which causes burning in the high temperature area and "oil frying" due to the accumulation of smoke liquid in the low temperature area.
