[0002] With the rapid development of science and technology and the economy, it is inevitable that electronic atomizing devices will gradually replace cigarettes. Electronic atomizing devices have a similar appearance and taste to cigarettes, and can produce smoke just like real cigarettes. Moreover, electronic atomizing devices do not contain harmful components such as tar and particulate matter, and do not produce lingering secondhand smoke. They do not affect the health of smokers or those around them, and are therefore very popular.

[0003] Existing electronic atomizing devices typically include an atomizing component and a battery component that powers the atomizing component. During user operation, the e-liquid within the atomizing component can easily leak into the battery component. To address this technical problem, those skilled in the art have employed various techniques to prevent e-liquid leakage. For example, Chinese patent application CN202223238865.0 discloses a leak-proof atomizing component, comprising a housing with an open end, a sealing element disposed at the open end of the housing, a bottom cover disposed outside the sealing element and fixed to the open end of the housing, and an atomizing core disposed within the housing. A liquid storage chamber is formed between the housing, the atomizing core, and the sealing element, and a recovery chamber is formed between the bottom cover and the sealing element, communicating with the lower end of the atomizing core for collecting leaked e-liquid. However, the aforementioned existing atomizing components suffer from drawbacks such as complex structure and high cost. Utility Model Content

[0005] To achieve the above objectives, in a first aspect, this application provides an atomizing assembly, comprising a liquid storage sleeve, a porous liquid suction element, an atomizing core, and a fixing base. The liquid storage sleeve is provided with a liquid storage cavity, and a first concave-convex portion is provided on the cavity wall of the liquid storage cavity. The porous liquid suction element is located inside the liquid storage cavity and is used to absorb e-liquid.

[0009] In one embodiment, both the liquid storage sleeve and the fixing base are made of plastic material.

[0010] In one embodiment, a limiting protrusion is provided on the wall of the liquid storage cavity, the porous liquid suction member is located between the limiting protrusion and the fixed base, the first end face of the porous liquid suction member is disposed facing the limiting protrusion, and the second end face of the porous liquid suction member is disposed facing the fixed base.

[0011] In one embodiment, the porous liquid-absorbing element is either a fiber column or a ceramic column.

[0012] In one embodiment, the atomizing assembly further includes a fiberglass tube located inside the liquid storage sleeve, and the porous liquid-absorbing element is at least partially sleeved on the fiberglass tube to contact the fiberglass tube; the liquid storage sleeve is provided with a smoke outlet, a first end of the fiberglass tube is connected to the atomizing core, and a second end of the fiberglass tube is connected to the liquid storage sleeve and communicates with the smoke outlet to discharge the smoke formed by the atomized liquid of the atomizing core to the smoke outlet.

[0013] In one embodiment, the atomizing core includes a fixing tube, a liquid guiding component, and a heating element. A first end of the fixing tube is inserted into the fixing base, and a second end of the fixing tube is inserted into the porous liquid-absorbing component and connected to the glass fiber tube. The liquid guiding component is located inside the fixing tube and is in contact with the porous liquid-absorbing component. The heating element is located inside the fixing tube and is in contact with the liquid guiding component, and is used to atomize the e-liquid at the liquid guiding component.

[0014] Secondly, this utility model also discloses an electronic atomizing device, including an atomizing component and a battery component connected to the atomizing component, wherein the battery component is used to power the atomizing component, and the atomizing component is the atomizing component described in any of the first aspects above.

[0021] Please refer to Figures 1-5 One embodiment of this application provides an atomizing component 100 for use in combination with a battery component 200 to form an electronic atomizing device. It includes a liquid storage sleeve 11, a porous liquid suction element 12, a fiberglass tube 13, an atomizing core 14, a fixing base 15, a magnetic suction element 16, an elastic sealing plug 17, and a first electrode 18. The liquid storage sleeve 11 is provided with a suction part 111 and a liquid storage chamber 112. The suction part 111 is located at one end of the liquid storage sleeve 11 and is provided with a smoke outlet 113 for discharging smoke. The liquid storage chamber 112 is used to store e-liquid, wherein the e-liquid can be made of propylene glycol, glycerol, and flavorings, etc. It is understood that as long as it can be atomized to form smoke, the material composition of the e-liquid is not specifically limited here.

[0022] The wall of the liquid storage chamber 112 is provided with a limiting protrusion 114 and a first concave-convex portion 115. The limiting protrusion 114 is arranged adjacent to the smoke outlet 113. There are multiple limiting protrusions 114, which are spaced apart and all located at the same radial position in the liquid storage chamber 112. The end of the liquid storage chamber 112 facing away from the smoke outlet 113 is provided with a cavity opening 116. The first concave-convex portion 115 is located inside the end of the liquid storage chamber 112 facing away from the smoke outlet 113 and is arranged adjacent to the cavity opening 116. There are two first concave-convex portions 115, which are spaced apart from each other.

[0023] The porous liquid-absorbing element 12 is located within the liquid storage chamber 112 and is used to absorb e-liquid. It can be made of materials such as fibers or ceramics, for example, fibers made from polypropylene, polyethylene, polyethylene terephthalate, polyamide, etc. These materials have good chemical stability and physical properties, such as high temperature resistance and corrosion resistance, making them suitable for environments where e-liquid is in contact for extended periods. It is understood that the ceramic is a porous ceramic, which absorbs e-liquid through its pores to lock in the e-liquid and prevent it from flowing freely. It is understood that as long as it can absorb e-liquid, the material of the porous liquid-absorbing element 12 is not specifically limited. The porous liquid-absorbing element 12 is located between the limiting protrusion 114 and the fixing base 15. The first end face of the porous liquid-absorbing element 12 faces the limiting protrusion 114, and the second end face faces the fixing base 15, thus ensuring reliable positioning. In one embodiment, the porous liquid-absorbing element 12 is either a fiber column or a ceramic column.

[0024] A fiberglass tube 13 is located inside the liquid storage sleeve 11. One end of the porous liquid suction element 12 is fitted onto the fiberglass tube 13 to contact it. The first end of the fiberglass tube 13 is connected to the atomizing core 14, and the second end is connected to the liquid storage sleeve 11 and communicates with the smoke outlet 113 to discharge the smoke formed by the atomized e-liquid from the atomizing core 14 to the smoke outlet 113. It is understood that the fiberglass tube 13 is a tube formed by braiding glass fiber threads. Conducting smoke through the fiberglass tube 13 not only reduces smoke condensation, but also allows the condensed e-liquid from the smoke outlet 113 to flow back into the porous liquid suction element 12, reducing the probability of the user inhaling condensed e-liquid.

[0025] The atomizing core 14 is located within the liquid storage chamber 112 and connected to the mounting base 15, meaning the atomizing core is mounted on the mounting base 15. The atomizing core 14 is in contact with the porous liquid suction member 12 and is used to atomize the e-liquid. The atomizing core 14 includes a fixing tube 141, a liquid guide 142, and a heating element 143. The first end of the fixing tube 141 is inserted into the mounting base 15, and the second end of the fixing tube 141 is inserted into the porous liquid suction member 12 and connected to the fiberglass tube 13. The liquid guide 142 is located within the fixing tube 141 and is in contact with the porous liquid suction member 12, used to conduct the e-liquid at the porous liquid suction member 12 to the heating element 143. The liquid guide 142 can be made of materials such as cotton or ceramic. The heating element 143 is located within the fixing tube 141 and is in contact with the liquid guide 142, used to atomize the e-liquid at the liquid guide 142. The heating element 143 can be a heating wire or a heating plate, etc. After the heating element 143 is energized and heats up, when the temperature of the liquid in the heating element 143 reaches its boiling point, the liquid in the heating element 143 can be atomized into smoke.

[0026] One end of the fixing seat 15 is inserted into the opening 116 of the liquid storage chamber 112, and the other end extends outside the liquid storage chamber 112 to seal the opening 116 of the liquid storage chamber 112. The fixing seat 15 is provided with a second protrusion 151 and a liquid injection hole 152. The second protrusion 151 is interference-fitted with the first protrusion 115 to prevent the liquid from leaking out between the fixing seat 15 and the wall of the liquid storage chamber 112. The first protrusion 115 and the second protrusion 151 are provided in a one-to-one correspondence. By using two or more first protrusions 115 and second protrusions 151 to cooperate, the sealing performance can be improved.

[0027] In this embodiment, the first concave-convex portion 115 is an annular connecting groove, coaxially arranged with the liquid storage chamber 112, and the second concave-convex portion 151 is an annular connecting protrusion embedded in the connecting groove. This structure facilitates assembly and provides good sealing. Both the liquid storage sleeve 11 and the fixing seat 15 are made of plastic material, thus ensuring a more stable and reliable connection and reducing the probability of detachment due to external forces. It is understood that in one embodiment, the first concave-convex portion 115 is an annular connecting protrusion, and the second concave-convex portion 151 is an annular connecting groove.

[0028] The injection hole 152 penetrates the two opposite ends of the fixing base 15 and communicates with the porous liquid suction member 12, allowing liquid to be injected into the porous liquid suction member 12. A magnetic suction member 16 is inserted into the injection hole 152 to seal it and is used for magnetic attraction with the battery assembly 200. The magnetic suction member 16 can be made of iron or ferromagnetic materials, as long as it can magnetically attract the battery assembly 200; the material composition is not specifically limited here. By fixing the magnetic suction member 16 inside the injection hole 152, not only is the sealing performance of the injection hole 152 improved, the manufacturing process simplified, and production efficiency increased, but the problem of adding a groove to fix the magnetic suction member 16, thus avoiding interference with the injection hole 152, is also avoided.

[0029] An elastic sealing plug 17 is inserted into the injection hole 152 and located between the porous liquid-absorbing member 12 and the magnetic suction member 16. The outer peripheral surface of the elastic sealing plug 17 elastically abuts against the wall of the injection hole 152, thereby further reducing the probability of liquid leakage. The cross-sectional area of ​​the end of the elastic sealing plug 17 facing away from the porous liquid-absorbing member 12 is larger than the cross-sectional area of ​​the end of the elastic sealing plug 17 facing the porous liquid-absorbing member 12, thus facilitating assembly and further improving sealing performance. The first electrode 18 is fixed on the mounting base 15 and electrically connected to the heating element 143. The first electrode 18 is used to electrically connect to the battery assembly 200 to obtain electrical energy from the battery assembly 200.

[0030] During production, the fiberglass tube 13 is first connected to the atomizing core 14 and the first electrode 18 is connected to the fixing base 15. Then, the porous liquid suction component 12 is put on the atomizing core 14 and the atomizing core 14 is fixed on the fixing base 15. Then, the fixing base 15, which is connected to the atomizing core 14 and the porous liquid suction component 12, is inserted into the liquid storage chamber 112. Then, the e-liquid is injected through the liquid injection hole 152. Finally, the elastic sealing plug 17 and the magnetic suction component 16 are installed.

[0031] Furthermore, this utility model also discloses an electronic atomizing device, including an atomizing component 100 and a battery component 200 connected to the atomizing component 100. The battery component 200 is used to supply power to the atomizing component 100, wherein the atomizing component 100 is the atomizing component 100 of the above embodiment. Since the atomizing component 100 of this electronic atomizing device has the same structure as the atomizing component 100 of the above embodiment, it also has the same technical effects, and its structure will not be described in detail here.

[0032] The battery assembly 200 of the electronic atomizing device includes a battery sleeve 21, an end cap 22, a bracket 23, a battery 24, a second electrode 25, a magnetic post 26, and a controller 27. The end cap 22 covers the first end of the battery sleeve 21, and the atomizing assembly 100 is detachably inserted into the second end of the battery sleeve 21. The bracket 23 is located inside the battery sleeve 21 and between the atomizing assembly 100 and the end cap 22. The battery 24 is mounted on the bracket 23 and electrically connected to the controller 27. The second electrode 25 and the magnetic post 26 are both fixed to the end of the bracket 23 facing the atomizing assembly 100. The second electrode 25 is in contact with the first electrode 18 and electrically connected to the controller 27 to transfer electrical energy from the battery 24 to the heating element 143 during operation.

[0033] The magnetic post 26 corresponds to the magnetic attractor 16 of the atomizing assembly 100 and they are magnetically attracted to each other, thereby reliably connecting the atomizing assembly 100 and the battery assembly 200 together. It is understood that the magnetic post 26 can be made of ferromagnetic material, as long as it can magnetically attract the magnetic attractor 16; its material is not specifically limited here. The controller 27 may include a microcontroller and an airflow sensor electrically connected to the microcontroller, as long as it can control the battery 24 to supply power to the heating element 143 when the user inhales the electronic atomizing device; its structure is not specifically limited here.

[0034] In summary, this utility model utilizes the cooperation between the liquid storage sleeve 11, the porous liquid suction member 12, and the fixing seat 15. The liquid storage sleeve 11 is provided with a liquid storage cavity 112, and a first concave-convex portion 115 is provided on the cavity wall of the liquid storage cavity 112. The porous liquid suction member 12 is located inside the liquid storage cavity 112 and is used to absorb e-liquid. The fixing seat 15 is at least partially inserted into the cavity opening 116 of the liquid storage cavity 112 to seal the cavity opening 116 of the liquid storage cavity 112. The fixing seat 15 is provided with a second concave-convex portion 151, which is interference-fitted with the first concave-convex portion 115. That is, the porous liquid suction member 12 locks in the e-liquid, and the interference fit between the second concave-convex portion 151 and the first concave-convex portion 115 seals the e-liquid and prevents leakage. In other words, the porous liquid suction member 12, the first concave-convex portion 115, and the second concave-convex portion 151 work together to seal the e-liquid. Therefore, compared with the prior art, the present invention does not require other sealing components to seal the fixed seat 15, thus the structure is simple and the cost is low.
