[0002] With the increasing concern about physical health, people have realized the harm of tobacco to the body, and thus electronic cigarettes have been invented. Electronic cigarettes have similar appearance and taste to cigarettes, but generally do not contain tar, suspended particles and other harmful components in cigarettes, greatly reducing the harm to the user's body, and thus are often used as a substitute for cigarettes for smoking cessation.

[0003] However, many electronic cigarettes have a difference in taste after being used for a period of time, and the consistency of smoking is poor, which affects the user experience. SUMMARY

[0004] Therefore, it is necessary to provide an atomization structure, an atomizer and an atomization device to solve the problem that the taste of a traditional electronic cigarette is easy to differ after being used for a period of time.

[0038] In an embodiment of the present application, an atomization device, such as an electronic cigarette or a medical atomization instrument, is provided for heating and atomizing a liquid.

[0039] Referring to Figure 1 , the atomization device comprises an atomizer 200 and an electric core (not shown in the figure), the electric core being used to supply power to the atomizer 200, and the atomizer 200 being used to heat and atomize a liquid, such as heating and atomizing tobacco tar.

[0040] Referring to Figures 1-4 , the atomizer 200 comprises a cartridge shell 210, a heating element 250 and an atomization structure 100, the atomization structure 100 being sleeved in the cartridge shell 210 and comprising a receiving part 10 and a flow guide part 30, the receiving part 10 having a receiving cavity 11 accommodating the heating element 250, the flow guide part 30 being connected with the receiving part 10, the flow guide part 30 being formed with a liquid guide through hole 31 communicating with the receiving cavity 11, and the flow guide part 30 having a flow guide section 341, the entire outer circumferential surface of the flow guide section 341 being reserved with a flow guide gap 35 with the cartridge shell 210. The flow guide gap 35 communicates with the receiving cavity 11, and the flow guide part 30 is formed with an air outlet hole 33 communicating with the flow guide gap 35. When the atomizer 200 works, the atomization structure 100 guides the tobacco tar into the receiving cavity through the liquid guide through hole 31, so that the heating element 250 in the receiving cavity absorbs the tobacco tar and heats and atomizes the tobacco tar. At the same time, when a user sucks the atomization device, the external airflow is guided to the atomization cavity and mixed with the atomized tobacco tar, and the airflow mixed with the atomized tobacco tar can flow to the air outlet hole 33 through the flow guide gap 35 between the flow guide section 341 and the cartridge shell 210, and then flow to the outside for the user to suck.

[0041] The flow guide portion 30 is spaced apart from the entire outer circumferential surface of the cartridge shell 210, and the entire outer circumferential surface of the flow guide portion 30 is formed with a flow guide gap 35, which allows airflow to flow to the air outlet hole 33 from each direction of the outer circumferential surface of the flow guide portion 30. If one side of the flow guide portion 30 is blocked, airflow can still flow to the air outlet hole 33 through the other side of the flow guide portion 30, which effectively ensures smooth airflow and prevents the electronic cigarette from affecting the smoking taste after being used for a period of time due to airway blockage. The smoking taste can be kept consistent, and the use experience can be improved.

[0042] The cartridge shell 210 is formed with an air outlet channel 212 and a liquid storage cavity 214, and the heating element 250 is arranged in the receiving cavity 11. The air outlet channel 212 is in communication with the liquid storage hole, and the liquid storage cavity 214 is in communication with the liquid guide through hole 31. The liquid storage cavity 214 of the cartridge shell 210 is used to store tobacco tar, and the tobacco tar in the liquid storage cavity 214 can enter the receiving cavity 11 and contact the heating element 250 through the liquid guide through hole 31, and then the heating element 250 can be used to heat and atomize the tobacco tar. At the same time, the air outlet channel 212 is in communication with the air outlet hole 33 of the atomization structure 100, and the airflow mixed with the atomized tobacco tar can flow to the air outlet channel 212 through the air outlet hole 33, and then flow to the user's mouth.

[0043] The atomizer 200 further comprises a base 230 having a first connecting end 232 and a second connecting end 234 connected to each other. The first connecting end 232 is connected to the cartridge shell 210, and the second connecting end 234 is spaced apart from the cartridge shell 210 to form an air passage 235 in communication with the flow guide gap 35. The receiving portion 10 is connected to the second connecting end 234. The first connecting end 232 is provided with an air inlet hole 233 in communication with the receiving cavity 11, and the second connecting end 234 is provided with an air passage 236 in communication with the air passage 235 and the receiving cavity 11. In this way, the atomization structure 100 is assembled in the cartridge shell 210 through the base 230. When the user inhales the atomization device, the external airflow can enter the receiving cavity 11 through the air inlet hole 233 on the base 230, mix with the atomized tobacco tar formed by heating in the receiving cavity 11, then enter the air passage 235 through the air passage 236 on the first connecting end 232, flow to the flow guide gap 35, and finally flow to the user's mouth from the air outlet hole 33 and the air outlet channel 212.

[0044] Optionally, the receiving cavity 11 formed on the receiving portion 10 has an opening facing the first connecting end 232, and the air inlet hole 233 on the first connecting end 232 communicates with the receiving cavity 11 through the opening of the receiving cavity 11. Moreover, the heating element 250 is loaded into the receiving cavity 11 through the opening of the receiving cavity 11, and after the heating element 250 absorbs the tobacco tar, the heating element 250 heats the absorbed tobacco tar, so that the atomized tobacco tar flows to the air passage 236 through the opening of the receiving cavity 11. Further optionally, the atomizer 200 further comprises a sealing sleeve 252, which is sleeved outside the heating element 250 and sealingly abuts between the heating element 250 and the inner wall 32 of the receiving cavity 11, so as to seal the heating element 250 and prevent liquid leakage of the heating element 250.

[0045] In addition, in order to enable the receiving portion 10 to be connected with the second connecting end 234 and enable the air passage 236 of the second connecting end 234 to communicate with the receiving cavity 11 and the air passage 235, a buckle is arranged on the receiving portion 10, the buckle abuts against the top wall of the air passage 236, and a space is reserved between the buckle and the bottom wall of the air passage 236 to allow the air passage 236 to remain unobstructed.

[0046] The flow guide portion 30 of the atomization structure 100 comprises an outer wall 34 and an inner wall 32, the inner wall 32 is sleeved in the outer wall 34, the inner wall 32 and the outer wall 34 form a liquid guide through hole 31 therebetween, and the inner wall 32 forms an air outlet hole 33 therearound. The flow guide portion 30 is arranged in a double-layer structure, which is ventilated in the middle and liquid-pervious on the outside, so as to guide the tobacco tar into the receiving cavity 11 and allow airflow to pass through. Specifically, the outer wall 34 has a flow guide section 341 and an assembly section 343, the assembly section 343 is arranged at one end of the flow guide section 341 away from the receiving portion 10, and the entire outer peripheral surface of the assembly section 343 is sealingly assembled with the cartridge shell 210, so as to sealingly assemble the atomization structure 100 in the cartridge shell 210 through the assembly section 343, seal the gap between the atomization structure 100 and the cartridge shell 210, and prevent the tobacco tar in the liquid storage cavity 214 of the cartridge shell 210 from leaking through the gap between the atomization structure 100 and the cartridge shell 210. Optionally, a sealing ring 50 is assembled between the assembly section 343 and the cartridge shell 210 to further improve the sealing effect.

[0047] After the flow guide portion 30 is arranged in a double-layer structure, in order to enable the air outlet hole 33 in the middle to communicate with the flow guide gap 35 on the outside of the outer wall 34, an air passage opening 342 is formed on the flow guide section 341 of the outer wall 34 and communicates with the air outlet hole 33, so that the air outlet hole 33 formed by the inner wall 32 communicates with the flow guide gap 35 through the air passage opening 342 on the outer wall 34. Optionally, the number of air passage openings 342 is two, and the two air passage openings 342 are oppositely arranged in a direction perpendicular to the circumferential direction of the air outlet hole 33.

[0048] Further, in order to conveniently guide the airflow to flow to the airflow hole, the width of the inner circumferential surface of the flow guide section 341 gradually decreases along the radial direction of the air outlet hole 33, that is, the closer the flow guide section 30 is to the base 230, the narrower the width of the outer circumferential surface of the flow guide section 30, and the larger the flow guide gap 35, so that in the direction in which the base 230 points to the air outlet passage 212, the flow guide gap 35 is in the shape of a downward-widening and upward-narrowing horn, and the airflow is conveniently guided to flow from the base 230 to the air outlet passage 212.

[0049] Optionally, in order to conveniently guide the tobacco tar in the liquid storage cavity 214 to flow to the storage cavity 11, the width of the inner circumferential surface of the flow guide section 341 gradually decreases along the radial direction of the air outlet hole 33, so that the liquid guide through hole 31 formed between the inner circumferential surface of the flow guide section 341 and the inner wall 32 is in the shape of a funnel, and the tobacco tar in the liquid storage cavity 214 is conveniently guided to flow to the storage cavity 11 through the liquid guide through hole 31.

[0050] Specifically, the outer wall 34 includes two oppositely arranged first sub-outer walls 34 and two second sub-outer walls 34 oppositely arranged and connected between the two first sub-outer walls 34, and the two first sub-outer walls 34 and the two second sub-outer walls 34 are both spaced apart from the cartridge shell 210 to form the flow guide gap 35. The two first sub-outer walls 34 are both provided with air passing openings 342 to communicate the flow guide gap 35 with the air outlet hole 33, and the two second sub-outer walls 34 are both arranged to incline toward each other in the direction in which the flow guide section 30 points to the storage section 10 to form the inclined inner circumferential surface of the flow guide section 341 and the outer circumferential surface of the flow guide section 341, thereby facilitating the flow of the tobacco tar and the airflow.

[0051] The storage section 10 includes a storage body 12 and a flow limiting lug 14, the storage body 12 is provided with the storage cavity 11, and the flow limiting lug 14 is arranged on the storage body 12. The flow limiting lug 14 is arranged on the storage body 12, and at least part of the outer circumferential surface of the flow limiting lug 14 abuts against the cartridge shell 210 to adjust the airflow flowing from the air passing passage 235 to the flow guide gap 35 through the length of the flow limiting lug 14 protruding outward, thereby preventing the airflow from being too large or too small when the aerosolization device is smoked.

[0052] Referring to Figures 1-4 In some embodiments, part of the outer circumferential surface of the flow limiting lug 14 abuts against the cartridge shell 210, and the remaining outer circumferential surface of the flow limiting lug 14 is spaced apart from the cartridge shell 210 to form an air passing gap 13, so that the airflow in the air passing passage 235 is allowed to flow to the flow guide gap 35 through the air passing gap 13 between the flow limiting lug 14 and the cartridge shell 210. Moreover, the length of the flow limiting lug 14 protruding outward is designed to make the airflow in the air passing gap 13 appropriate.

[0053] Specifically, the flow-limiting lugs 14 include two opposite first sub-outer circumferential surfaces and two opposite second sub-outer circumferential surfaces, both of the second sub-outer circumferential surfaces are connected with the two first sub-outer circumferential surfaces, both of the first sub-outer circumferential surfaces are in abutment with the cartridge shell 210, and both of the second sub-outer circumferential surfaces are provided with the air passage gap 13 in abutment with the cartridge shell 210.

[0054] Referring to Figures 5-7 In some other embodiments, all of the outer circumferential surfaces of the flow-limiting lugs 14 are in abutment with the cartridge shell 210, which means that no gap is provided between the flow-limiting lugs 14 and the cartridge shell 210, and the air passage holes 15 are formed on the flow-limiting lugs 14 to allow the airflow in the airflow passage 235 to flow to the flow-guiding gap 35 through the air passage holes 15. The diameter and number of the air passage holes 15 can be adjusted to adjust the airflow, so as to design an atomizer with a suitable flow rate. Alternatively, one air passage hole 15 can be formed on the flow-limiting lug 14, or two air passage holes 15 or other numbers of air passage holes 15 can be formed, and the air passage holes 15 with different numbers and sizes can be designed according to the demand of the airflow.

[0055] Referring to Figures 3-4 In addition, after the external airflow enters the atomizer 200, the airflow is heated by the heating element 250, and after the airflow with a high temperature contacts the airflow passage inner wall 32 with a low temperature, condensate is formed in the airflow passage. In order to prevent the condensate from flowing out and affecting the normal use, the condensate collection groove 17 is formed on the side of the flow-limiting lug 14 facing the flow-guiding section 341, so as to collect the condensate in the airflow passage through the condensate collection groove 17.

[0056] Further, the atomization structure 100 further includes a liquid absorbing element 20, which is arranged in the condensate collection groove 17 and is used to absorb the condensate in the condensate collection groove 17, so as to store the condensate in the liquid absorbing element and prevent the condensate from flowing randomly and causing leakage. Alternatively, the liquid absorbing element 20 is a porous structure, such as a sponge, which has the ability to absorb liquid.

[0057] In addition, the first fitting end 232 of the base 230 is formed with a condensate storage cavity 237, the condensate storage cavity 237 is located on the airflow path from the air inlet hole 233 to the air outlet 236, and the condensate storage cavity 237 is in communication with the airflow passage and can also be used to collect the condensate formed in the airflow passage.

[0058] Based on the same concept, in an embodiment of the present application, there is also provided an atomizer 200 as described above, which comprises a cartridge shell 210, a heating element 250, and an atomization structure 100, the atomization structure 100 is sleeved in the cartridge shell 210 and comprises a receiving part 10 and a flow guide part 30, the receiving part 10 has a receiving cavity 11 for accommodating the heating element 250, the flow guide part 30 is connected with the receiving part 10, the flow guide part 30 is formed with a liquid guide through hole 31 communicating with the receiving cavity 11, and the flow guide part 30 has a flow guide section 341, and the entire outer periphery of the flow guide section 341 is spaced apart from the cartridge shell 210 to form a flow guide gap 35. The flow guide gap 35 communicates with the receiving cavity 11, and the flow guide part 30 is formed with an air outlet hole 33 communicating with the flow guide gap 35. When the atomizer 200 is working, the atomization structure 100 guides the tobacco tar into the receiving cavity through the liquid guide through hole 31, so that the heating element 250 in the receiving cavity absorbs the tobacco tar and heats and atomizes the tobacco tar. At the same time, when a user sucks the atomization device, the external airflow is guided to the atomization cavity and mixed with the atomized tobacco tar, and the airflow mixed with the atomized tobacco tar can flow to the air outlet hole 33 through the flow guide gap 35 between the flow guide section 341 and the cartridge shell 210, and then flow to the outside for the user to suck.

[0059] The entire outer periphery of the flow guide part 30 is formed with the flow guide gap 35, which can allow the airflow to flow to the air outlet hole 33 from each direction of the outer periphery of the flow guide part 30. If one side of the flow guide part 30 is blocked, the airflow can still flow to the air outlet hole 33 through the other side of the flow guide part 30, which can effectively ensure the smooth flow of the airflow, prevent the electronic cigarette from affecting the suction taste after being used for a period of time due to airway blockage, keep the suction taste consistent, and improve the use experience.
