Description

Technical Field

[0001] The present invention relates to the field of electronic smoking devices, and in particular to an aerosol generating assembly installed in an atomizer, an assembling method, and an atomizer and an electronic cigarette using the aerosol generating assembly. Background Art

[0002] In the reusable electronic cigarette atomizers currently on the market, the atomizer cores mostly adopt a detachable and replaceable connection method. The atomizer core in the prior art generally includes a heating element and a liquid guide layer surrounding the heating element. The liquid guide layer usually uses fiber cotton, but the fiber cotton is wrapped in a full circle multiple times, that is, a single layer of fiber cotton is wrapped with multiple layers to form a liquid guide layer. During manual operation, the tightness of each winding operation will vary to varying degrees, thereby affecting the consistency of the atomizer product and the atomization effect. When the fiber cotton is wound too tightly, the smoke liquid penetration efficiency of the atomizer core will be too low, and the heating element cannot obtain sufficient smoke liquid. In addition, the atomizer in the prior art is not suitable for the structure of multiple atomizer cores, and the product is not flexible in use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an aerosol generating component and an assembly method thereof, as well as an atomizer and an electronic cigarette with high smoke liquid penetration efficiency and high product consistency.

[0004] In order to solve the above technical problems, the present invention provides an aerosol generating assembly, comprising an outer sleeve and at least one atomizing core located in the outer sleeve, the atomizing core comprising a heating element for atomizing smoke liquid and a first liquid conducting layer coated around the heating element, a bracket for fixing the atomizing core is also provided in the outer sleeve, the bracket has a accommodating cavity for placing the atomizing core and at least one notch opened on the side wall, a second liquid conducting layer is also coated around the bracket, the second liquid conducting layer is in contact with the first liquid conducting layer through the notch, thereby conducting the smoke liquid into the first liquid conducting layer.

[0005] Furthermore, a plurality of liquid inlet holes are provided on the side wall of the outer sleeve, and at least a portion of the liquid inlet holes are aligned with the notches on the bracket.

[0006] Furthermore, a cross section formed by the first liquid-conducting layer covering the periphery of the heating element is located within the notch and directly faces the liquid inlet hole aligned with the notch.

[0007] Preferably, the heating element is a spiral heating wire, a cylindrical heating net or a cylindrical heating sheet, and the first liquid guiding layer is a fiber cotton layer, which is wrapped around the outer periphery of the heating element, thereby forming an aerosol channel on the inner side of the heating element.

[0008] As one of the specific implementations, the first liquid-conducting layer is formed by a fiber cotton layer surrounding the periphery of the heating element, and the cross section formed by closing two ends of the fiber cotton layer is located in the notch.

[0009] As another specific implementation, the first liquid-conducting layer is formed by two fiber cotton layers surrounding the periphery of the heating element, and two cross sections formed by closing two ends of the two fiber cotton layers are located in the two symmetrically arranged notches.

[0010] As one of the specific implementations, the aerosol generating assembly includes more than two atomizing cores, and more than two spaced-apart accommodating cavities are correspondingly opened on the bracket, and a side of each accommodating cavity is connected to one of the notches.

[0011] Furthermore, both ends of the heating element are provided with connecting wires, wherein the connecting wire on one end is located outside the first liquid-conducting layer, and the connecting wire on the other end is located inside the first liquid-conducting layer.

[0012] Preferably, the thickness of the second liquid-conducting layer is smaller than the thickness of the first liquid-conducting layer.

[0013] The present invention also provides a method for assembling an aerosol generating assembly, comprising the following steps:

[0014] The first liquid guide layer is wrapped around the periphery of the heating element to form a predetermined number of atomizing cores;

[0015] Then, the atomizer core is placed in the corresponding accommodation cavity on the bracket;

[0016] Then, the second liquid-conducting layer is coated on the periphery of the support and is loaded into the outer sleeve together with the support loaded with the atomizing core.

[0017] Furthermore, the first liquid guide layer is formed by enclosing the heating element in a single layer using one or two fiber cotton layers. After the atomizer core is placed in the corresponding accommodating cavity on the bracket, the excess fiber cotton layer extending outside the notch is cut off so that the end of the fiber cotton layer is basically flush with the notch.

[0018] Furthermore, when the bracket loaded with the atomizer core is installed into the outer sleeve, the notch is aligned with the liquid inlet hole on the outer sleeve.

[0019] The present invention also provides an atomizer, comprising a shell assembly and an aerosol generating assembly installed inside the shell assembly, wherein a liquid storage chamber for storing smoke liquid is also formed inside the shell assembly, and the aerosol generating assembly may be the aerosol generating assembly described in each of the above-mentioned optimization schemes, and the aerosol generating assembly is suitable for heating the smoke liquid to generate aerosol for human inhalation.

[0020] The present invention also provides an electronic cigarette, comprising the above-mentioned atomizer and a power supply component connected to the atomizer.

[0021] The beneficial effect of the present invention is that compared with the wrapping method of multi-layer winding of fiber cotton in the prior art, the aerosol generating assembly in the present invention adopts a new assembly method, which includes a first liquid guide layer and a second liquid guide layer, both of which are single-layer structures in the form of enclosure, which can avoid the difference in tightness caused by artificial wrapping of multiple circles of fiber cotton, thereby affecting the liquid guide efficiency. At the same time, the second liquid guide layer is coated on the periphery of the above-mentioned bracket, and the second liquid guide layer can guide the smoke liquid to penetrate inward from each notch on the bracket, which is suitable for multiple atomization cores to heat at the same time; and the section on the first liquid guide layer is located in the notch, which is further conducive to the infiltration of the smoke liquid inward, ensuring that the smoke liquid provided to the heating element is sufficient.

[0030] The structure and use principle of the aerosol generating assembly, atomizer and electronic cigarette involved in the present invention are further described below through specific embodiments.

[0031] See also Figure 1As shown, this embodiment provides an atomizer 10 with a liquid injection function, including a shell assembly 100, an end cap assembly 200 and a base assembly 400 respectively connected to the upper and lower ends of the shell assembly, and an aerosol generating component 300 installed inside the shell assembly 100. A liquid storage chamber 101 for loading smoke liquid is formed inside the shell assembly 100, and the upper and lower ends of the liquid storage chamber 101 are respectively sealed by the end cap assembly 200 and the base assembly 400. When the user removes the end cap assembly 200, smoke liquid can be added to the liquid storage chamber 101. The aerosol generating component 300 is connected to the power supply assembly through the base assembly 400, and when the user removes the base assembly 400, the internal aerosol generating component 300 can be replaced. In addition, a nozzle 103 is installed on the end cover assembly 200 . The interior of the nozzle 103 is connected to the interior of the aerosol generating component 300 . The aerosol generating component 300 is used to atomize the tobacco liquid in the liquid storage chamber 101 to generate aerosol. The user inhales the generated aerosol through the nozzle 103 .

[0032] See also Figure 2 As shown, the housing assembly 100 has a liquid injection end 104, and at least one liquid injection port 107 connected to the liquid storage chamber 101 is provided on the liquid injection end 104. Specifically in this embodiment, the liquid injection end 104 has an end face 105 abutting against the end cover assembly 200, and two symmetrical liquid injection ports 107 are provided on the end face 105. A ventilation pipe 102 is also provided at the center of the end face 105, and the ventilation pipe 102 is connected to the interior of the above-mentioned aerosol generating assembly 300.

[0033] The end cap assembly 200 is detachably connected to the liquid injection end 104, and is used to open or close the liquid injection port 107. When the user removes the end cap assembly 200, the user can add tobacco liquid to the liquid injection port 107 through the liquid injection container. The end cap assembly 200 and the liquid injection end 104 are provided with corresponding buckle structures. The liquid injection end 104 is suitable for rotating a predetermined angle after being inserted into the end cap assembly 200, so as to form a buckle connection with the end cap assembly 200. Compared with the threaded connection method in the prior art, the buckle connection method has a simple structure, can reduce product costs, and only needs to rotate a small angle to remove the end cap assembly 200, which is relatively convenient to operate.

[0034] As one of the specific snap-fit ​​structures in the present invention, at least one convex card 106 protruding outward is provided on the injection end 104. In this embodiment, two symmetrical arrangements are provided. A slot 203 for inserting the convex card 106 and an arc groove 204 provided along the circumferential direction are axially provided on the inner side of the end cover assembly 200. When the end cover assembly 200 is connected to the housing assembly 100, the convex card 106 enters the arc groove 204 along the slot 203, and can be buckled with the arc groove 204 by horizontally rotating a certain angle. Preferably, a limiting structure is provided in the arc groove 204, and the limiting structure is used to limit the rotation angle of the injection end 104. For example, the snap-fit ​​connection can be completed by rotating 120 degrees. On the contrary, when the injection end 104 is rotated back 120 degrees along the arc groove 204, it can be separated from the end cover assembly 200. The above-mentioned limiting structure includes a pair of limiting posts 209 . The limiting posts 209 protrude from the inner wall of the arc-shaped groove 204 to prevent the convex clamp 106 from further rotating.

[0035] Recombination Figure 2 and Figure 3 As shown, a sealing portion 205 is provided at the bottom of the end cap assembly 200, and the sealing portion 205 is configured to seal the injection port 107 when the end cap assembly 200 is buckled with the injection end 104. Specifically, the end cap assembly 200 includes a cover body 201 covered on the injection end 104 and a fixing seat 202 connected to the cover body 201, and the sealing portion 205 is installed on the fixing seat 202. The cover body 201 and the fixing seat 202 are nested and fixedly assembled, and a gap is formed between the two, so that the injection end 104 can be inserted. The fixing seat 202 has a hollow cavity 206 that penetrates therethrough. When the sealing portion 205 abuts against the end face 105 on the injection end 104, the lower end of the hollow cavity 206 is connected to the ventilation pipe 102, and the suction nozzle 103 is inserted into the upper end of the hollow cavity 206, so that the suction nozzle 103 and the ventilation pipe 102 are connected through the hollow cavity 206.

[0036] As a preferred solution in this embodiment, the end cap assembly 200 further includes an elastic component, and when the end cap assembly 200 is buckled with the liquid injection end 104, the elastic component elastically abuts against the liquid injection end 104. The elastic component includes a spring 208 and a lap joint 207 abutting against the spring 208. When the end cap assembly 200 and the liquid injection end 104 are in a connected state, the spring 208 is compressed, and elastic force can be provided to make the lap joint 207 overlap the liquid injection end 104, so that the rotational friction between the end cap assembly 200 and the liquid injection end 104 can be increased, thereby preventing the end cap assembly 200 from falling off due to misoperation, thereby causing liquid smoke to leak.

[0037] See also Figure 4As shown, the present invention also provides an embodiment of an electronic cigarette 30. The electronic cigarette 30 includes the above-mentioned atomizer 10 and a power supply assembly 20 connected to the atomizer 10, and the power supply assembly 20 is electrically connected to the above-mentioned base assembly 400 to supply power to the internal aerosol generating assembly 300.

[0038] See also Figures 5A to 5F As shown, the present invention provides an embodiment of an aerosol generating assembly 300 having only one atomizing core and an assembly process of the aerosol generating assembly 300 .

[0039] The above-mentioned aerosol generating assembly 300 includes an outer sleeve 301 and an atomizing core 302 located in the outer sleeve 301, the atomizing core 302 includes a heating element 306 for atomizing smoke liquid and a first liquid-conducting layer 304 wrapped around the outer periphery of the heating element 306, and a bracket 303 for fixing the atomizing core 302 is also arranged in the outer sleeve 301, the bracket 303 has a receiving cavity 3031 for placing the atomizing core 302 and at least one notch 3032 opened on the side wall, specifically two symmetrically arranged in this embodiment. A second liquid-conducting layer 305 is also wrapped around the outer periphery of the bracket 303, and the second liquid-conducting layer 305 contacts the first liquid-conducting layer 304 through the notch 3032, thereby conducting the smoke liquid into the first liquid-conducting layer 304 for heating and atomization by the heating element 306.

[0040] In this embodiment, the thickness of the second liquid-conducting layer 305 is less than that of the first liquid-conducting layer 304, which can accelerate the penetration of the smoke liquid from the liquid storage cavity 102 into the first liquid-conducting layer 304, and the first liquid-conducting layer 304 with a larger thickness can absorb more smoke liquid, ensuring that the smoke liquid supply to the heating element 306 is sufficient. In addition, the second liquid-conducting layer 305 is located in the gap between the outer sleeve 301 and the bracket 303, avoiding the situation that the liquid storage cavity 102 leaks from the assembly space between the outer sleeve 301 and the bracket 303.

[0041] Furthermore, a plurality of liquid inlet holes 3011 are provided on the side wall of the outer sleeve 301, and at least a part of the liquid inlet holes 3011 are aligned with the notch 3032 on the bracket 303. Moreover, the section 3041 formed by the first liquid guide layer 304 covering the outer periphery of the heating element 306 is located in the notch 3032 and directly faces the liquid inlet hole 3011 aligned with the notch 3032. Specifically in this embodiment, four evenly distributed liquid inlet holes 3011 are provided on the side wall of the outer sleeve 301, wherein two opposite liquid inlet holes 3011 are aligned with the symmetrical notches 3032 on the bracket 303, which is conducive to the smoke liquid to penetrate the second liquid guide layer 305 and the first liquid guide layer 304 in sequence in a faster path and be conducted to the heating element 306. The section 3041 formed by the first liquid guide layer 304 is located in the notch 3032, which can further facilitate the smoke liquid to penetrate inwards and ensure sufficient liquid supply.

[0042] As a preferred solution, the heating element 306 in this embodiment adopts a spiral heating wire, and the first liquid guide layer 304 adopts a fiber cotton layer, which is wrapped around the outer periphery of the heating element 306, thereby forming an aerosol channel 307 on the inner side of the heating element, and the aerosol generated by the atomization of the smoke liquid is guided to the upper ventilation pipe 102 through the aerosol channel 307. Of course, the heating element 306 can also adopt common heating element forms such as a cylindrical heating net or a cylindrical heating sheet.

[0043] like Figure 5A and Figure 5B The first liquid conducting layer 304 is formed by two fiber cotton layers 3042 and 3043 surrounding the periphery of the heating element 306 , and two cross sections 3041 formed by closing the two ends of the two fiber cotton layers 3042 and 3043 are located in the two symmetrically arranged notches 3032 .

[0044] As a specific implementation measure, both ends of the heating element 306 have connecting wires, wherein the connecting wire 3061 on one end is located outside the first liquid-conducting layer 304, and the connecting wire on the other end is located inside the first liquid-conducting layer 304 (not shown), so as to prevent the connecting wires at both ends of the heating element 306 from short-circuiting. The connecting wire 3061 located outside contacts with the outer sleeve 301 as a negative electrode, and the connecting wire located inside contacts with the electrode ring 310 installed at the bottom of the outer sleeve 301 as a positive electrode.

[0045] The following follows FIG. 5A to FIG. 5F The assembly method of the aerosol generating assembly 300 is described in detail with reference to the assembly sequence shown.

[0046] like Figure 5AFirst, the atomizer core 302 is made, and two pre-pressed fiber cotton layers 3042 and 3043 are sandwiched around the heating element 306 and surrounded on the periphery of the heating element 306 to form a single-layer structure first liquid guide layer 304, and the two ends of the fiber cotton layers 3042 and 3043 are closed and combined. At the same time, the connecting wire 3061 on one end of the heating element 306 passes over the first liquid guide layer 304 and extends downward from the outside, and the connecting wire on the other end is located on the inside of the first liquid guide layer 304.

[0047] like Figure 5B , then put the manufactured atomizer core 302 into the corresponding accommodating cavity 3031 on the bracket 303, and close the ends of the fiber cotton layers 3042 and 3043 so that the excess fiber cotton layer 3044 extends outward from the notches 3032 on both sides of the bracket 303; the thickness of the fiber cotton layers 3042 and 3043 is preset and can fit closely with the inner wall of the bracket 303.

[0048] like Figure 5C Then, the excess fiber cotton layer 3044 extending to the outside of the notch 3032 is cut off, so that the ends of the two fiber cotton layers 3042 and 3043 are basically flush with the notch 3032, or slightly protrude from the notch 3032.

[0049] like Figure 5D , and then another fiber cotton layer with a smaller thickness is wrapped around the outer periphery of the bracket 303, and only one layer is wrapped to form a second liquid-conducting layer 305. It can be understood that the second liquid-conducting layer 305 can also be made of non-woven fabrics or other polymer foamed fiber layer materials.

[0050] like Figure 5E Then, the support 303 wrapped with the second liquid guide layer 305 and the internal atomizer core 302 are installed into the outer sleeve 301. During assembly, it should be noted that the two notches 3032 on the support 303 are aligned with the two liquid inlet holes 3011 on the outer sleeve 301.

[0051] like Fig. 5F Finally, the insulating ring 308, the sealing ring 309 and the electrode ring 310 are respectively assembled at the lower end of the outer sleeve 301, and the insulating ring 308 insulates the electrode ring 310 from the outer sleeve 301 and the bracket 303. At the same time, the two ends of the outer sleeve 301 are respectively provided with threaded parts 3012 and 3013 in advance, wherein the threaded part 3012 is used to connect with the above-mentioned ventilation pipe 102, and the threaded part 3013 is used to connect with the above-mentioned base assembly 400. The sealing ring 309 is also sleeved on the lower end of the outer sleeve 301 to prevent the leakage of smoke liquid between the aerosol generating assembly 300 and the base assembly 400.

[0052] See also FIG. 6A to FIG. 6DAs shown, the present invention also provides an aerosol generating assembly 300a having two atomizing cores. The aerosol generating assembly 300a includes two atomizing cores 302a, and the two atomizing cores 302a are assembled together inside the accommodating cavity 3031a in the bracket 303a. As an alternative design, the two atomizing cores 302a can also be placed in two spaced accommodating cavities opened in the bracket 303a.

[0053] During the assembly process, two atomizer cores 302a are first made, and a single fiber cotton layer 3041a is used to surround the outer periphery of the heating element 306a, and the ends of the fiber cotton layer 3041a are closed to form a first liquid guide layer 304a on the outer periphery of the heating element 306a. Then, two fiber cotton layers 3042a are clamped on both sides of the two atomizer cores 302a to fix the two atomizer cores 302a, and then placed in the accommodating cavity 3031a on the bracket 303a, and the excess part of the fiber cotton layer 3041a protruding from the notch 3032a at the closed position of the ends of the fiber cotton layer 3041a is cut off; then the second liquid guide layer 305a is wrapped around the outside of the bracket 303a, and is installed in the outer sleeve 301a, and finally the electrode ring and other components are installed to assemble and form the aerosol generating assembly 300a.

[0054] The first liquid-conducting layers 304a in the two atomizer cores 302a are in contact with each other in the accommodating cavity 3031a, so as to form liquid conduction, thereby preventing a lack of smoke liquid in one of the atomizer cores 302a from causing dry burning and producing a burnt smell.

[0055] See also 7A to 7E As shown, the present invention also provides an aerosol generating assembly 300b with three atomizing cores. Specifically, the aerosol generating assembly 300b includes an outer sleeve 301b and three atomizing cores 302b located in the outer sleeve 301b, the atomizing core 302b includes a heating element 306b for atomizing smoke liquid and a first liquid guide layer 304b wrapped around the outer heating element 306b, and a bracket 303b for fixing the three atomizing cores 302b is also provided in the outer sleeve 301b, and three axial accommodating cavities 3031b for placing the atomizing cores 302 are provided at intervals on the bracket 303b, and each accommodating cavity 3031b is connected to a notch 303b on the side, so that the smoke liquid on the outer second liquid guide layer 305b can penetrate into each atomizing core 302b.

[0056] Combination Fig. 7A and Figure 7BAs shown, as a preferred solution in this embodiment, in order to optimize the path of the smoke liquid entering the atomizer core 302b, a smoke liquid channel 3033b for the flow of smoke liquid is opened between every two adjacent accommodating chambers 3031b. The purpose of opening the smoke liquid channel 3033b is to allow the smoke liquid to flow and penetrate each other between the three atomizer cores 302b through the smoke liquid channel 3033b, thereby preventing too little smoke liquid in a certain atomizer core 302b from causing dry burning and producing a burnt smell.

[0057] In order to further improve the efficiency of the smoke liquid flowing into each atomizer core 302b, a smoke liquid penetration hole 3034b connected to the smoke liquid channel 3033b is provided between two adjacent notches 3031b on the side wall of the bracket 303b, and the smoke liquid penetration hole 3034b can be connected to the two receiving chambers 3031b corresponding to the notches 3031b on both sides through the smoke liquid channel 3033b. In addition to entering the inside and outside of the atomizer core 302 through the notches 3032 on each receiving chamber 3031b, the smoke liquid on the second liquid guide layer 305b can also penetrate into the two adjacent atomizer cores 302b through the smoke liquid penetration hole 3034b, thereby improving the smoke liquid entry efficiency and ensuring sufficient smoke liquid supply.

[0058] Correspondingly, a first liquid inlet hole 3011b and a second liquid inlet hole 3012b are provided on the side wall of the outer sleeve 301b, and the first liquid inlet hole 3011b is square, rectangular or elliptical, and is aligned with the notch 3031b. At the same time, the cross-section formed by the first liquid conductive layer 304b in the notch 3031b is also aligned with the first liquid inlet hole 3011b; and the second liquid inlet hole 3012b is aligned with the smoke liquid penetration hole 3034b.

[0059] In addition, different from the above-mentioned aerosol generating component 300, in the structure of the aerosol generating component 300b, the threaded portion 3013b connected to the ventilation pipe 102 is arranged at the upper end of the outer sleeve 301, while the threaded portion 3035b connected to the base component 400 is arranged at the lower end of the bracket 303b.

[0060] The production of the aerosol generating assembly 300b is similar to the assembly process of the aerosol generating assembly 300a with two atomizing cores. First, three atomizing cores 302b are produced, that is, a fiber cotton layer 3041b is respectively used to surround the outer periphery of the heating element 306b, so that the ends of the fiber cotton layer 3041b are closed to form a first liquid guide layer 304b on the outer periphery of the heating element 306b. Then, the three atomizing cores 302b are respectively placed in three different accommodating cavities 3031b on the bracket 303b, and the excess part of the fiber cotton layer 3041b protruding from the notch 3032b at the closed position of the ends of the fiber cotton layer 3041b is cut off; then, the second liquid guide layer 305b is wrapped around the outside of the bracket 303b, and is installed in the outer sleeve 301b; finally, the electrode ring and other components are installed to assemble and form the aerosol generating assembly 300b.

[0061] See also FIG. 8A to FIG. 8D As shown, the present invention also provides an aerosol generating assembly 300c having four atomizing cores, the aerosol generating assembly 300c includes an outer sleeve 301c, a bracket 303c, and four atomizing cores 302c installed in the bracket 303c, and four axial accommodating cavities 3031c are provided on the bracket 303c. Similarly, the atomizing core 302c also includes a heating element 306c and a first liquid guiding layer 304c on the periphery, and a second liquid guiding layer 305c is coated on the periphery of the bracket 303c.

[0062] Similar to the above-mentioned aerosol generating assembly 300b with three atomizing cores, in the structure of the aerosol generating assembly 300c, the four first liquid guiding layers 304c are also formed by only one fiber cotton layer 3041c surrounding the heating element 306c, closing the ends and then cutting off the excess parts. Similarly, a smoke liquid channel 3033c is provided between adjacent accommodating cavities 3031c, and a smoke liquid penetration hole 3034c is also provided between adjacent notches 3032c on the bracket 303c. The assembly method of the aerosol generating assembly 300c is in accordance with FIG. 8A to FIG. 8D The assembly process of the aerosol generating assembly 300b having three atomizing cores can be referred to in the order shown, and will not be described in detail here.

[0063] Finally, it should be noted that the above embodiments sequentially introduce aerosol generating assemblies with one to four atomizing cores, but it does not exclude that the aerosol generating assembly can also have more atomizing cores. Aerosol generating assemblies with different numbers of atomizing cores can be replaced with each other, and users can choose to replace aerosol generating assemblies with different atomizing cores according to the amount of smoke required and the taste requirements when smoking.

[0064] The above embodiments are only some implementation methods listed in this specification for the convenience of understanding the content of the invention. They are not any limitation to the technical solution of the present invention, nor are they an exhaustive list of all feasible implementation plans. Therefore, any minor improvements or equivalent substitutions made to the structure, process or steps of the present invention should be included in the scope of protection.
