Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a liquid-conducting cotton atomization unit. Background Art

[0002] With the continuous development of electronic cigarettes, the continuous innovation and progress of technology, the experience of electronic cigarettes is getting better and better, and more and more people are accepting it. In some existing electronic cigarettes, the atomization core formed by inserting liquid-conducting cotton in the heating body as the liquid-conducting medium is increasingly popular among consumers due to its advantages such as being pure natural, low cost, and good atomization taste. However, there are also many problems in the process of mass production using liquid-conducting cotton as the liquid-conducting medium, as follows:

[0003] 1. The atomization core formed by inserting liquid guide cotton in the heating element generally has liquid entering from both ends and heat in the middle. The path for liquid to enter the middle of the heating element is long, and the liquid supply in the middle is prone to insufficient, and the temperature in the middle of the heating element is prone to be too high. The liquid guide cotton is easily carbonized and affects its life when it is exposed to high temperature for a long time.

[0004] 2. Since the liquid-conducting cotton is inserted into the heating element, in order to ensure good contact between the liquid-conducting cotton and the heating element, the outer diameter of the liquid-conducting cotton needs to be larger. However, if the liquid-conducting cotton is too large, it is easy to cause deformation of the heating element. The heating element is easy to compress the cotton, resulting in insufficient oil supply and easy burning. Therefore, the size of the liquid-conducting cotton is difficult to control.

[0005] 3. When the outer diameter of the liquid-conducting cotton is thinner, it is easier for the liquid-conducting cotton to penetrate into the middle of the heating element, and the liquid-conducting cotton and the heating element are likely to have poor local contact. If the local part of the heating element is not in contact with the liquid-conducting cotton, it is easy to cause the problem of local high temperature burning of the heating element, affecting the user experience. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a liquid-conducting cotton atomization unit for improving the heating condition of a heating body.

[0007] The technical solution adopted by the present invention to solve the technical problem is: to provide a liquid-conducting cotton atomization unit, comprising a heating element, liquid-conducting cotton and at least one liquid-conducting support tube; the liquid-conducting cotton is axially arranged in the heating element, and the liquid-conducting support tube is parallel to the axial direction of the liquid-conducting cotton and is arranged in the liquid-conducting cotton;

[0013] Preferably, the end of the liquid-conducting support tube extending out of the liquid-conducting cotton is in a flared shape.

[0014] Preferably, the outer diameter of the liquid-conducting cotton is smaller than the inner diameter of the heating element; the liquid-conducting support tube is passed through the liquid-conducting cotton to expand the liquid-conducting cotton so that it is in full contact with the heating element.

[0015] Preferably, the outer diameter of the liquid-conducting cotton is larger than the inner diameter of the heating element, and a channel extending axially and penetrating opposite ends thereof is provided in the liquid-conducting cotton; the liquid-conducting support tube is arranged in the channel.

[0016] Preferably, the heating portion is a spiral structure formed by spirally winding a heating wire; two electrode portions are formed at both ends of the heating wire respectively.

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown, the liquid-conducting cotton atomizing unit of the first embodiment of the present invention comprises a heating element 10, liquid-conducting cotton 20 and a liquid-conducting support tube 30. The liquid-conducting cotton 20 is axially arranged in the heating element 10; the liquid-conducting support tube 30 is parallel to the axial direction of the liquid-conducting cotton 20 and is arranged in the liquid-conducting cotton 20. After the heating element 10 is powered on and heated, the smoke liquid adsorbed on the liquid-conducting cotton 20 in contact with it is heated and atomized to form smoke.

[0034] The heating element 10 includes a heating portion 11 and two electrode portions 12 respectively connected to both ends of the heating portion 11. The electrode portion 12 is mainly used as a positive and negative external power source, and the heating portion 11 is mainly used to generate heat to heat and atomize the smoke liquid after being powered on.

[0035] The outer diameter of the liquid-conducting cotton 20 is smaller than the inner diameter of the heating element 10, so that the liquid-conducting cotton 20 can easily and completely penetrate into the heating element 10 without causing deformation of the heating element 10. The liquid-conducting support tube 30 is inserted into the liquid-conducting cotton 20 to expand the outer diameter of the liquid-conducting cotton 20 so that it can fully contact with the heating element 10.

[0036] In this embodiment, the heating element 10 is made of a heating wire. The heating portion 11 is a spiral structure formed by spirally winding the heating wire; two electrode portions 12 are formed at both ends of the heating wire. The two electrode portions 12 are at opposite ends of the heating portion 11 and extend outward perpendicularly to the axial direction of the heating portion 11. According to the installation requirements in the electronic cigarette, the electrode portion 12 can also extend outward parallel to the axial direction of the heating portion 11.

[0037] The corresponding heating element 10 is a structure made of heating wire, and the length of the liquid-conducting cotton 20 is greater than the length of the heating part 11 (ie, the spiral structure), so that the opposite ends of the liquid-conducting cotton 20 extend out of the two ends of the heating part 11 respectively, so as to facilitate the absorption of smoke liquid.

[0038] Furthermore, in this embodiment, the length of the liquid guide support tube 30 is greater than the length of the heating part 11, which enlarges the liquid guide cotton 20 so that its outer diameter is increased to fully contact the inner surface of the heating part 11, avoiding the problem that part of the heating part 11 cannot contact the liquid guide cotton 20. At the same time, the structural strength of the liquid guide cotton 20 is improved, and then the structural strength of the entire atomization unit is improved, which is beneficial to assembly and fixation in the electronic cigarette.

[0039] The overall length of the liquid guide support tube 30 is less than that of the liquid guide cotton 20, and the whole is buried therein. The liquid guide support tube 30 is provided with at least one liquid outlet 31 corresponding to the heating part 11. Due to the hollow structure of the liquid guide support tube 30, the opposite ends are open to form ports, and the smoke liquid can enter from the two opposite ports of the tube, and after coming out from the liquid outlet 31, it is conducted to the heating part 11 through the liquid guide cotton 20 for heating and atomization.

[0040] The liquid outlet hole 31 may be disposed on at least one side of the side wall of the liquid guide support tube 30 . There may be one or more liquid outlet holes 31 on each side, and the shape of the liquid outlet holes 31 is not limited.

[0041] like Figure 4 As shown, in the liquid-conducting cotton atomization unit of the second embodiment of the present invention, at least one liquid inlet hole 32 is further provided on at least one end of the liquid-conducting support tube 30 as required. In the axial direction of the liquid-conducting support tube 30, the liquid inlet hole 32 is located at least on one side of the liquid outlet hole 31 and is spaced apart from the liquid outlet hole 31. The provision of the liquid inlet hole 32 allows the smoke liquid adsorbed by the liquid-conducting cotton 20 to enter the liquid-conducting support tube 30 through the port of the liquid-conducting support tube 30 and the liquid inlet hole 32, and then flow out from the liquid outlet hole 31 to be adsorbed by the corresponding liquid-conducting cotton part, and then heated and atomized by the heating part.

[0042] like Figure 5 As shown, the liquid-conducting cotton atomizing unit of the third embodiment of the present invention comprises a heating element 10, liquid-conducting cotton 20 and a liquid-conducting support tube 30. The liquid-conducting cotton 20 is axially arranged in the heating element 10; the liquid-conducting support tube 30 is parallel to the axial direction of the liquid-conducting cotton 20 and is arranged in the liquid-conducting cotton 20, so as to expand the liquid-conducting cotton 20 so as to make it fully contact with the heating element 10. After the heating element 10 is powered on and heated, the smoke liquid adsorbed on the liquid-conducting cotton 20 in contact with it is heated and atomized to form smoke.

[0043] In this embodiment, the heating element 10 is made of a heating wire. The liquid outlet 31 on the liquid guide support tube 30 is provided with a liquid inlet hole as required. The specific configuration of the heating element 10, the liquid guide support tube 30 and the liquid guide cotton 20 is referred to the first and second embodiments above, and will not be repeated here.

[0044] This embodiment is different from the first and second embodiments in that the end surface of at least one end of the liquid guide support tube 30 is provided with an inclined surface to form a pointed structure 33, which is conducive to the insertion of the liquid guide support tube 30 into the liquid guide cotton 20 and can also enhance the introduction of smoke liquid.

[0045] like Figure 6 As shown, the liquid-conducting cotton atomization unit of the fourth embodiment of the present invention includes a heating body 10, a liquid-conducting cotton 20 and a liquid-conducting support tube 30. The liquid-conducting cotton 20 is axially arranged in the heating body 10; the liquid-conducting support tube 30 is parallel to the axial direction of the liquid-conducting cotton 20 and is arranged in the liquid-conducting cotton 20, so as to expand the liquid-conducting cotton 20 so that it is in full contact with the heating body 10. After the heating body 10 is powered on and heated, the smoke liquid adsorbed on the liquid-conducting cotton 20 in contact with it is heated and atomized to form smoke. The electrode part 12 is mainly used as a positive and negative external power source, and the heating part 11 is mainly used to generate heat after power is turned on to heat and atomize the smoke liquid.

[0046] The heating element 10 includes a heating part 11 and two electrode parts 12 respectively connected to the two ends of the heating part 11. The electrode part 12 is mainly used as a positive and negative external power source, and the heating part 11 is mainly used to generate heat after power is turned on to heat and atomize the smoke liquid. The liquid guide support tube 30 is provided with at least one liquid outlet 31 corresponding to the heating part 11. The smoke liquid can enter from the two opposite ports of the liquid guide support tube 30, and after coming out of the liquid outlet 31, it is conducted to the heating part 11 through the liquid guide cotton 20 for heating and atomization.

[0047] In this embodiment, the heating element 10 is made of a heating wire. The length of the liquid guide support tube 30 is greater than the length of the heating portion 11, which enlarges the outer diameter of the liquid guide cotton 20 to fully contact the inner surface of the heating portion 11, and at the same time improves the structural strength of the liquid guide cotton 20, thereby improving the structural strength of the entire atomization unit, which is conducive to assembly and fixation in the electronic cigarette.

[0048] The liquid outlet hole 31 on the liquid guide support tube 30 is provided, and the liquid inlet hole is provided as needed. The specific arrangements of the heating element 10, the liquid guide support tube 30 and the liquid guide cotton 20 refer to the first and second embodiments above, and will not be repeated here.

[0049] Furthermore, the present embodiment is different from the first and second embodiments described above in that the length of the liquid guide support tube 30 is greater than the length of the liquid guide cotton 20. At least one end of the liquid guide support tube 30 extends axially and extends out of the end surface of the liquid guide cotton 20, so that the end of the liquid guide support tube 30 is outside the liquid guide cotton 20, which helps to guide the smoke liquid, and the smoke liquid is then adsorbed by the liquid guide cotton 20 through the liquid outlet hole 31 on the liquid guide support tube 30, and finally conducted to the heating part 11 for heating and atomization.

[0050] In addition, the end 34 of the liquid guiding support tube 30 extending outside the liquid guiding cotton 20 also facilitates the cooperation of a fixing member, etc., to fix the entire atomization unit, etc.

[0051] like Figure 7 As shown, in the liquid-conducting cotton atomization unit of the fifth embodiment of the present invention, the end 34 of the liquid-conducting support tube 30 extending out of the liquid-conducting cotton 20 is expanded as needed to form an expanded shape, so that the smoke liquid can enter the liquid-conducting support tube 30 more smoothly.

[0052] like Figure 8 , 9 As shown, the liquid-conducting cotton atomizing unit of the sixth embodiment of the present invention comprises a heating element 10, liquid-conducting cotton 20 and a liquid-conducting support tube 30. The liquid-conducting cotton 20 is axially arranged in the heating element 10; the liquid-conducting support tube 30 is parallel to the axial direction of the liquid-conducting cotton 20 and is arranged in the liquid-conducting cotton 20, so as to expand the liquid-conducting cotton 20 so that it is in full contact with the heating element 10. After the heating element 10 is powered on and heated, the smoke liquid adsorbed on the liquid-conducting cotton 20 in contact with it is heated and atomized to form smoke.

[0053] The heating element 10 includes a heating part 11 and two electrode parts 12 connected to both ends of the heating part 11. The electrode part 12 is mainly used as a positive and negative external power source, and the heating part 11 is mainly used to generate heat after power is turned on to heat and atomize the smoke liquid. The liquid guide support tube 30 is provided with at least one liquid outlet 31 corresponding to the heating part 11. The smoke liquid entering the liquid guide support tube 30 can be conducted from the liquid outlet 31 to the heating part 11 through the liquid guide cotton 20 for heating and atomization.

[0054] In this embodiment, the heating element 10 is a heating tube, the middle section of the heating tube is hollowed out to form a heating portion 11, and two opposite ends of the heating tube form two electrode portions 12. The hollowing out of the heating portion 11 allows it to form a structure in which multiple heating rings are connected in sequence, such as Figure 8 The structure shown in ; the heating portion 11 can also be a hollow shape with multiple through holes distributed therein, etc.

[0055] The outer diameter of the liquid-conducting cotton 20 is smaller than the inner diameter of the heating element 10 , so that the liquid-conducting cotton 20 can easily and completely penetrate into the heating element 10 without causing deformation of the heating element 10 .

[0056] The length of the liquid-conducting cotton 20 is greater than that of the heating tube, and the opposite ends of the liquid-conducting cotton 20 extend out of the electrode part 12 respectively, so as to facilitate the absorption of smoke liquid. The liquid-conducting support tube 30 is arranged in the liquid-conducting cotton 20, and the liquid-conducting cotton 20 is enlarged to increase its outer diameter so as to fully contact with the inner surface of the heating part 11, and at the same time, the structural strength of the liquid-conducting cotton 20 is improved, and then the structural strength of the entire atomization core is improved, which is more conducive to assembly and fixation in the electronic cigarette. Among them, the length of the liquid-conducting support tube 30 is greater than the length of the heating part 11, and can also be greater than the length of the entire heating tube.

[0057] Furthermore, the structure of the liquid-conducting support tube 30 in this embodiment can refer to the liquid-conducting support tubes 30 in the first to fifth embodiments, which will not be described in detail here.

[0058] The support rod in the first embodiment has an overall length less than that of the liquid-conducting cotton 20, is buried in the liquid-conducting cotton 20, and has a pointed head at one end to facilitate insertion into the liquid-conducting cotton 20. Referring also to the support rod in the second embodiment, at least one end extends out of the end of the liquid-conducting cotton 20 and is bent to form a positioning portion, which effectively prevents the support rod from falling out of the liquid-conducting cotton 20.

[0059] like Fig.10 As shown, the liquid-conducting cotton atomizing unit of the seventh embodiment of the present invention is different from the sixth embodiment described above, and includes a plurality of liquid-conducting support tubes 30. The plurality of liquid-conducting support tubes 30 are arranged parallel to each other in the axial direction and penetrate the liquid-conducting cotton 20.

[0060] like Fig.11 As shown, the liquid-conducting cotton atomizing unit of the eighth embodiment of the present invention comprises a heating element 10, liquid-conducting cotton 20 and a liquid-conducting support tube 30. The liquid-conducting cotton 20 is axially arranged in the heating element 10; the liquid-conducting support tube 30 is parallel to the axial direction of the liquid-conducting cotton 20 and is arranged in the liquid-conducting cotton 20, so as to expand the liquid-conducting cotton 20 so that it is in full contact with the heating element 10. After the heating element 10 is powered on and heated, the smoke liquid adsorbed on the liquid-conducting cotton 20 in contact with it is heated and atomized to form smoke.

[0061] The heating element 10 includes a heating portion 11 and two electrode portions 12 respectively connected to both ends of the heating portion 11. The electrode portion 12 is mainly used as a positive and negative external power source, and the heating portion 11 is mainly used to generate heat to heat and atomize the smoke liquid after being powered on.

[0062] The heating element 10 may be a spiral structure made of heating wires, or a heating tube. For details, please refer to the related description of the first embodiment or the seventh embodiment.

[0063] In this embodiment, the outer diameter of the liquid-conducting cotton 20 is greater than the inner diameter of the heating element 10. In order to allow the liquid-conducting cotton 20 to easily and completely penetrate the heating element 10 without causing deformation of the heating element 10, a channel 21 extending axially and passing through opposite ends of the liquid-conducting cotton 20 is provided. The provision of the channel 21 provides sufficient compression space for the liquid-conducting cotton 20 so that it can be compressed into the heating element 10.

[0064] The liquid guide support tube 30 is inserted into the channel 21 of the liquid guide cotton 20 to appropriately expand the compressed liquid guide cotton 20 so that it can fully contact the inner surface of the heating element 10, ensuring the continuous conduction of smoke and liquid in various parts of the heating element 10 for heating and atomization.

[0065] The liquid-conducting cotton atomization unit of the present invention is applied to products such as electronic cigarettes, has a long service life, and improves the atomization effect and user experience effect.
