Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generation, in particular to an atomization module, an aerosol generation device and an atomization kit. Background Art

[0002] Aerosol generating devices are also known as virtual cigarettes, electronic cigarettes, steam cigarettes, etc. They are mainly used for quitting smoking or replacing cigarettes. Aerosol generating devices heat the smoke oil to atomize it, and the atomized smoke oil flows out from the mouthpiece for the user to inhale.

[0003] Some aerosol generating devices include a cigarette cartridge and a cigarette rod, wherein the cigarette cartridge is provided with an oil storage bin for storing the smoke oil. During the manufacturing and use of the cigarette cartridge, the cigarette cartridge often needs to be filled with oil. In some cases, after the sealing silicone is sealed and connected to the oil storage bin, the smoke oil is injected into the oil storage bin by injection, that is, the needle of the syringe passes through the sealing silicone and injects the smoke oil into the oil storage bin. When the needle of the syringe is pulled out of the sealing silicone, the sealing silicone automatically heals to avoid oil leakage.

[0004] However, after the sealing silicone is pierced by the needle of the syringe, it may stretch too quickly and fail to heal. When the sealing silicone cannot heal after being pierced, a gap will appear on the sealing silicone, and the e-liquid will easily flow out from the gap, posing a risk of oil leakage.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] Please also read Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a structural schematic diagram of an atomization module provided in one embodiment of the utility model; Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the atomization module; Figure 3 yes Figure 1 Schematic diagram of the oil injection method of the atomization module.

[0034] An atomization module 100 provided in one embodiment of the present invention comprises: a suction nozzle 10, an oil storage tank 20, an oil sealing member 30 and an atomization assembly 40, wherein the suction nozzle 10 is connected to the oil storage tank 20, the oil storage tank 20 is provided with an oil storage cavity 21, the oil storage cavity 21 comprises an oil filling port 211, the oil filling port 211 is located on a side of the oil storage tank 20 close to the suction nozzle 10, and the oil filling port 211 faces the suction nozzle 10;

[0035] The oil sealing member 30 seals the oil filling port 211. The oil sealing member 30 includes a sealing layer 31 and an extended film layer 32. The extended film layer 32 is connected between the sealing layer 31 and the oil storage tank 20. The sealing layer 31 and the extended film layer 32 are an integrated structure.

[0036] The atomizing assembly 40 includes an atomizing chamber 41 and an atomizing core 42 installed in the atomizing chamber 41 . One end of the atomizing chamber 41 is connected to the suction nozzle 10 , and the other end of the atomizing chamber 41 is arranged in the oil storage tank 20 away from the suction nozzle and connected to the oil storage tank 20 .

[0037] Here, it should be noted that the above-mentioned atomization module 100 can be used as part of a separate cigarette cartridge, that is, the product is a cigarette cartridge, and the cigarette cartridge can be independently filled with oil. It can also be used as part of the aerosol generating device 300, that is, the product is an electronic cigarette, and the electronic cigarette can be filled with oil. But it is not limited to the above two embodiments. Here, the atomization module 100 is taken as an example of a cigarette cartridge. In addition, in this embodiment, the oil storage tank 20 is a separate part, and in some other embodiments, the oil storage tank 20 can be formed by enclosing the shell of the atomization module 100.

[0038] The stretch film layer 32 is in the form of a film, and the thickness of the sealing layer 31 is greater than that of the stretch film layer 32. The stretch film layer 32 is manufactured integrally with the sealing layer 31. In the specific manufacturing process, it means that a film treatment (chemical method) is performed on one side of the sealing layer 31. The sealing layer 31 has strong ductility before the film treatment, that is, the sealing layer 31 is easily torn directly after puncture. After the film treatment, the sealing layer 31 can be uniformly extended under the action of the stretch film layer 32, thereby improving the tensile and tearing resistance and avoiding the direct tearing of the sealing layer 31. Both the sealing layer 31 and the stretch film layer 32 can be punctured. After the sealing layer 31 is punctured, the stretch film layer 32 can be restored to its original state, and the sealing layer 31 can be extended under the action of the stretch film layer 32 to restore the sealing layer to its original state.

[0039] In the actual oil filling process, oil is filled into the oil storage chamber 21 through an injection device. The injection device generally adopts a needle syringe, which can be a single needle syringe or multiple needle syringes. The needle syringe pierces the sealing layer 31 and the stretch film layer 32 to fill the oil storage chamber 21 with oil. After the needle syringe is withdrawn from the oil storage chamber 21, a needle hole will be left on the sealing layer 31 and the stretch film layer 32. If the stretch film layer 32 is not provided, the needle hole on the sealing layer 31 may be unable to heal itself due to the rapid tearing of the sealing layer 31, that is, the sealing layer 31 has undergone plastic deformation. At this time, the needle hole still remains, and the oil storage chamber 21 cannot be closed, resulting in poor sealing effect and oil leakage.

[0040] By providing the stretchable film layer 32, the sealing layer 31 can be prevented from being directly torn. In other words, the sealing layer 31 is uniformly stretched under the action of the stretchable film layer 32, thereby improving the tear resistance. After the needle syringe is withdrawn from the oil storage cavity 21, the sealing layer 31 and the stretchable film layer 32 quickly self-heal due to their own high ductility, that is, the sealing layer 31 and the stretchable film layer 32 block the oil filling port 211 again to achieve the oil sealing effect and avoid oil leakage. After the sealing layer 31 is combined with the stretchable film layer 32, the mechanical strength and wear resistance of the entire oil sealing component 30 can also be improved, thereby extending its service life.

[0041] It is understandable that the sealing layer 31 is usually made of a relatively soft elastic material to improve its sealing performance, and the stretch film layer 32 is usually made of a relatively hard film material. After the sealing layer 31 and the stretch film layer 32 are integrally formed, on the one hand, the stretch film layer 32 can provide better support for the sealing layer 31, can better maintain the overall shape of the sealing layer 31, and reduce the deformation scale of the sealing layer 31 during the puncture process. On the other hand, after the needle syringe is pulled out, the stretch film layer 32 can disperse the stress, promote the elastic recovery of the sealing layer 31, and guide the sealing layer 31 to return to a state close to its original state to avoid oil leakage.

[0042] In the present embodiment, the atomization assembly 40 further includes an air duct 43, and the atomization chamber 41 is opened in the air duct 43. In some other embodiments, the atomization chamber 41 may be enclosed by the inner wall of the oil storage tank 20. The air duct 43 is provided with an oil inlet 431, and the oil inlet 431 is located on the side wall of the air duct 43 at one end away from the suction nozzle 10. The atomization core 42 is installed in the air duct 43. Here, it is necessary to briefly explain that the atomization core 42 adopts a heating wire and oil-conducting cotton. In some other embodiments, the atomization core 42 may adopt other structures such as a ceramic heating core. When the user uses the suction nozzle to draw, the smoke oil enters the air duct 43 from the oil inlet 431, and the atomization core 42 heats the smoke oil to form smoke. The smoke flows to the suction nozzle 10 through the atomization chamber 41 of the air duct 43 for the user to draw.

[0043] It should be further explained that the oil inlet 431 is opened on the side wall of the atomization chamber 41 away from the suction nozzle 10. When the oil storage tank 20 is filled with oil, the entire oil storage tank 20 can be inverted. In other words, when the atomization module 100 is filled with oil, the suction nozzle 10 is located below the oil storage tank 20, and the injection equipment pierces and fills the oil filling cavity 21 with oil from bottom to top, that is, from the suction nozzle 10 to the oil storage tank 20.

[0044] See also Figure 3 When injecting oil in the manner shown in the figure, the oil will first accumulate on the side of the oil storage bin 20 close to the stretch film layer 32, and the air pressure in the oil storage chamber 21 will increase, and the gas will enter the atomization chamber 41 from the oil inlet 431. As the oil in the oil storage chamber 21 continues to increase, the gas will be continuously discharged until the injection is completed, and the air pressure in the oil storage chamber 21 is not much different from the external atmospheric pressure. After the oil injection is completed, the atomization device can be placed upright.

[0045] In one embodiment, the sealing layer 31 is a silicone sealing layer, and the stretch film layer 32 is one of a nylon film layer, a Teflon film layer or a PET film layer (polyethylene terephthalate film layer).

[0046] Specifically, the sealing layer 31 is made of silicone material, which has good elasticity and shrinkage properties, and is convenient for the rapid healing of the sealing layer 31. The stretchable film layer 32 can be made of materials such as nylon, Teflon or PET, which are relatively hard and can help the sealing layer 31 to recover to its original state more quickly and avoid oil leakage. Preferably, the stretchable film layer 32 is made of Teflon material.

[0047] See also Figure 4 and Figure 5 , Figure 4 yes Figure 1 Schematic diagram of the explosion structure of the atomization module; Figure 5 yes Figure 2 Enlarged view of part A in .

[0048] In one embodiment, the atomization module 100 also includes a snap-fit ​​component 50, which includes a first snap-fit ​​portion 51 and a snap-fit ​​groove 52. The first snap-fit ​​portion 51 is snap-fitted with the circumferential outer wall of the oil storage tank 20, the sealing layer 31 and the stretch film layer 32 are accommodated in the snap-fit ​​groove 52, and the snap-fit ​​component 50 is against the surface of the sealing layer 31 that is away from the stretch film layer 32. The snap-fit ​​component 50 also includes a puncture hole 53, which is arranged corresponding to the position of the oil filling port 211.

[0049] Specifically, after the buckle 50 is matched with the oil storage bin 20, the sealing layer 31 and the stretch film layer 32 are accommodated in the buckle groove 52. In other words, the bottom of the buckle groove 52 abuts against the surface of the sealing layer 31 on the side away from the stretch film layer 32. The purpose of this arrangement is that the buckle 50 and the oil storage bin 20 form a clamping method to fix the position of the sealing layer 31 and the stretch film layer 32, so as to ensure the oil sealing effect of the sealing layer 31 and the stretch film layer 32 and prevent oil leakage.

[0050] It can be understood that after the fastener 50 is fastened with the oil storage bin 20, the upper and lower side surfaces of the oil sealing member 30 are respectively abutted against the oil storage bin fastener 50 and the oil storage bin 20, so that the oil sealing member 30 is clamped between the fastener 50 and the oil storage bin 20, thereby ensuring the assembly stability of the oil sealing member 30.

[0051] In this embodiment, the snap fastener 50 and the oil storage bin 20 have an extrusion effect on the oil sealing member 30, thereby improving the sealing effect of the oil sealing member 30 on the oil storage bin 20 and enabling the oil sealing member 30 (sealing layer 31 and stretch film layer 32) to heal more quickly to avoid oil leakage. In addition, since the upper surface of the oil storage bin 20 abuts against the lower surface of the oil sealing member 30, the oil storage bin 20 has a bearing and supporting effect on the oil sealing member 30 to prevent the oil sealing member 30 from sinking.

[0052] Moreover, after the fastener 50 is matched with the oil storage bin 20, the puncture hole 53 corresponds to the oil filling port 211, so that the injection device passes through the puncture hole 53 and punctures the sealing layer 31 within the projection range of the puncture hole 53 directly opposite the sealing layer 31 to fill the oil. In the specific implementation process, the fastener 50 and the oil storage bin 20 can be assembled in advance and then transported; and the oil can be filled at the end to avoid oil leakage during transportation.

[0053] See also Figure 6 , Figure 6 yes Figure 1 Schematic diagram of the structure of the snap-on parts in the atomization module.

[0054] In addition, it should be noted that the buckle 50 is generally in the shape of a cover. During the assembly process, the buckle 50 is buckled with the oil storage bin 20 along the direction from the suction nozzle 10 to the oil storage bin 20, and the first buckle portion 51 is buckled with the circumferential outer wall of the oil storage bin 20. In this embodiment, a buckle groove 52 is provided on the first buckle portion 51, and the oil storage bin 20 includes a protrusion 22, which is located on the circumferential outer wall of the oil storage bin 20. When the first buckle portion 51 is matched with the oil storage bin 20, the protrusion 22 extends into the buckle groove 52 to complete the buckle connection between the buckle 50 and the oil storage bin 20.

[0055] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 7 yes Figure 1 A schematic diagram of the explosion structure of the snap-fit ​​parts and the oil storage tank in the atomization module; Figure 8 yes Figure 5 Schematic diagram of the cross-sectional structure of the fastener in FIG.

[0056] In one embodiment, the buckle 50 also includes a buckle body 54 and a second buckle portion 55, the first buckle portion 51 and the second buckle portion 55 are both connected to the buckle body 54, the second buckle portion 55 is arranged along the edge of the puncture hole 53, and the second buckle portion 55 is extended from the suction nozzle 10 to the oil storage tank 20. The second buckle portion 55 abuts against the sealing layer 31, and part of the surface of the sealing layer 31 is recessed along the direction from the suction nozzle 10 to the oil storage tank 20.

[0057] Specifically, after the buckle 50 is matched with the oil storage bin 20, the second buckle portion 55 abuts against the sealing layer 31, and the sealing layer 31 is elastic. The second buckle portion 55 causes the sealing layer 31 to deform in the direction close to the oil storage bin 20, that is, the sealing layer 31 and the stretch film layer 32 are recessed in the direction close to the oil storage bin 20. The purpose of such a setting is to stretch the surfaces of the sealing layer 31 and the stretch film layer 32 to form tension. When the injection device punctures the sealing layer 31 and the stretch film layer 32 and is withdrawn, the sealing layer 31 and the stretch film layer 32 will quickly self-heal due to the surface tension.

[0058] Moreover, after the surface tension of the sealing layer 31 and the stretch film layer 32 is generated, it can prevent the sealing layer 31 and the stretch film layer 32 from wrinkling due to their own gravity, and the thickness of the wrinkled part is uneven. For example, when the injection device punctures the thicker part, it may be impossible to puncture, resulting in poor oil injection effect.

[0059] It should be noted that the buckle body 54 , the first buckle portion 51 and the second buckle portion 55 are manufactured integrally, the first buckle portion 51 and the buckle body 54 are combined to form a buckle groove 52 , and the second buckle portion 55 and the first buckle portion 51 extend in the same direction.

[0060] See also Figure 4 In one embodiment, an adjustment gap 60 is provided between the orthographic projection of the second buckle portion 55 along the direction from the suction nozzle 10 to the oil storage tank 20 and the edge side wall of the oil filling port 211, and the adjustment gap 60 is ≥ 0.1 mm and ≤ 0.5 mm.

[0061] Specifically, the second buckle portion 55 is arranged along the puncture hole 53, and the puncture hole 53 and the oil filling port 211 are both roughly circular openings, and the puncture hole 53 and the oil filling port 211 are arranged correspondingly. It can be understood that the center of the puncture hole 53 and the center of the oil filling port 211 are roughly located on the same axis, and the radius of the puncture hole 53 is smaller than the radius of the oil filling port 211. Preferably, the difference in radius between the oil filling port 211 and the puncture hole 53 is between 0.1mm and 0.5mm. In this embodiment, 0.35mm is preferably used to achieve the best effect. The purpose of such a setting is that the buckle body 54 is clamped with the oil seal 30 of the oil storage bin 20, and the oil seal 30 extends in the horizontal direction, that is, the sealing layer 31 and the stretch film layer 31 extend in the horizontal direction; the second buckle portion 55 abuts against the sealing layer 31, so that the sealing layer 31 and the stretch film layer 32 are recessed toward the oil storage cavity 21. In other words, the stretch film layer 32 is recessed toward the oil storage cavity 21 during the horizontal extension process until the stretch film layer 32 abuts against the side wall of the oil filling port 211. The setting of the adjustment gap 60 can prevent the stretch film layer 32 from excessive displacement and can also provide the oil seal 30 with a suitable range of motion. When the oil seal 30 abuts against the side wall of the oil filling port 211, a better sealing effect can be achieved.

[0062] In addition, if the radius difference between the oil filling port 211 and the puncture port 53 is too small, such as less than 0.1 mm, the range of movement of the oil seal 30 is too small, and wrinkles may be generated on the surface of the sealing layer 31 and the stretch film layer 32, that is, the thickness of the sealing layer 31 and the stretch film layer 32 increases, and it is not easy to be punctured by the injection device. If the radius difference between the oil filling port 211 and the puncture port 53 is too large, such as greater than 0.5 mm, the range of movement of the oil seal 30 is too large, and when the oil seal 30 is against the side wall of the oil filling port 211, a large tension is generated on the surface of the sealing layer 31 and the stretch film layer 32, and it is easy to form a tear after the injection device punctures, that is, the sealing layer 31 and the stretch film layer 32 cannot return to their original state, and it is not easy for the sealing layer 31 and the stretch film layer 32 to quickly self-heal.

[0063] In one embodiment, the thickness of the oil seal 30 is ≥0.5 mm and ≤2.0 mm.

[0064] Specifically, the thickness of the oil seal 30 is in the range of 0.5 mm to 2.0 mm. Preferably, the integrated structure of the sealing layer 31 and the stretch film layer 32 is a finished sheet material with a thickness of 0.15 mm.

[0065] See also Figure 2 In one embodiment, the suction nozzle 10 includes a suction port 11 , and the puncture port 53 is arranged opposite to the suction port 11 .

[0066] Specifically, the suction port 11 is roughly circular, and may also be elliptical, but is not limited thereto. The puncture port 53 is arranged opposite to the suction port 11. When filling oil, the needle of the syringe can pass through the suction port 11 and the puncture port 53 in sequence to achieve oil filling. In this way, there is no need to disassemble the suction nozzle 10 during the oil filling process, which is convenient and quick. The purpose of such arrangement is that the above-mentioned atomization module 100 can be filled with oil after the suction nozzle 10 is matched with the oil storage tank 20. In short, the finished product of the atomization module 100 can be transported first, and after the transportation is completed, the suction port 11 and the puncture port 53 are passed through the injection device for oil filling. In addition, the atomization module 100 can also be filled with oil when the snap fastener 50 is matched with the oil storage tank 20, and then matched with the suction nozzle 10 after the oil storage tank 20 is filled with oil. In other words, the atomizer module 100 in the present invention can be filled with oil in two ways, one is to fill the oil during the matching process of the atomizer module 100; the other is to fill the oil after the atomizer module 100 is matched. The operator can adjust the actual steps of filling the oil according to the actual situation. For example: the atomizer module 100 may leak oil due to bumps during transportation. Then, after the atomizer module 100 is transported, the injection device can be used to puncture the puncture port 53 through the suction port 11 to fill the oil to avoid oil leakage during transportation.

[0069] Here, it should be noted that the aerosol generating device 200 can be manufactured in the form of a cartridge and a cigarette rod, or in an integrated manner (not a splicing method of a cartridge and a cigarette rod), wherein the aerosol generating device 200 manufactured in either manner includes the above-mentioned atomization module 100. That is, the aerosol generating device 200 also includes the technical effects of the above-mentioned atomization module 100, which will not be described in detail here.

[0070] See also Figure 3 , Fig.10 and Fig.11 , Fig.10 is a schematic cross-sectional structure diagram of an atomization kit provided by another embodiment of the utility model; Fig.11 yes Fig.10 Enlarged view of part B in .

[0071] The utility model also provides an atomization kit 300, the atomization kit 300 includes the above-mentioned atomization module 100; the atomization kit 300 also includes a syringe 310, the syringe 310 includes a needle head 3101, a needle tube part 3102 and a liquid storage part 3103, the needle tube part 3102 is connected between the needle head 3101 and the liquid storage part 3103, the needle tube part 3102 is provided with a liquid outlet 31021 on one side of the needle head 3101, the liquid storage part 3103 can store corresponding liquid (in this embodiment, the liquid is smoke oil), the needle head 3101 can puncture along the direction from the sealing layer 31 to the stretch film layer 32, and the liquid in the liquid storage part 3103 can be injected into the oil storage cavity 21 through the liquid outlet 31021.

[0072] It should be noted here that the atomization kit 300 includes the atomization module 100 and the syringe 310. In a specific product, the atomization kit 300 can be sold separately as an independent product, that is, the customer can complete the oil filling process of the atomization module 100 through independent operation.

[0073] During the puncture process, the needle head 3101 plays the role of piercing the sealing layer 31 and the stretch film layer 32. As the needle head 3101 pierces, the needle tube 3102 enters the oil filling chamber until the oil storage chamber 21 is connected with the liquid outlet 31021, and then the liquid storage part 3103 injects the tobacco oil into the oil filling chamber through the liquid outlet 31021. The purpose of this arrangement is that during the puncture process of the needle head 3101, the sealing layer 31 and the stretch film layer 32 will produce debris. If the liquid outlet 31021 is opened on the needle head 3101, then the debris will block the liquid outlet 31021, resulting in poor oil filling effect of the syringe 310.

[0074] In addition, it should be noted that the injection device mentioned above can be composed of multiple injectors 310 to facilitate industrial oil injection.

[0075] In one embodiment, the needle head 3101 is a conical structure.

[0076] Here, it is necessary to further explain that the needle head 3101 is a conical structure, wherein a cone refers to a geometric body formed by a curved surface formed by rotating the other two sides of a right triangle 360 ​​degrees with the straight line where the right angle side is located as the rotation axis; it is not an oblique cone. The purpose of adopting a conical structure is to avoid the situation where an ordinary oblique-mouth needle or an oblique-cut needle directly tears the sealing layer 31 and the stretch film layer 32 and cannot be directly healed.
