[0002] In the structural design of traditional electronic atomization devices, atomized liquid often leaks due to various factors (such as vibration, temperature changes, etc.), resulting in a decline in user experience and damage to the equipment. Therefore, the industry has invented an isolation structure that separates the oil core from the atomization device, so that the electronic atomization device is in a state where the atomized liquid and the atomization core are separated before use, thereby effectively preventing the penetration and leakage of the atomized liquid.

[0003] However, during the heating process of existing electronic atomization device products, condensation often occurs due to the temperature difference between the internal heating components and the external environment. If the condensation is not properly handled, it may flow out from some air flow channels that are not completely sealed, affecting device performance and user satisfaction. In addition, improperly designed air flow channels will still cause the atomized liquid to leak during inhalation, affecting user experience and service life. [Utility Model Content]

[0004] In order to solve the technical problem of condensate leaking from the air flow channel inside the existing electronic atomization device, the utility model provides an electronic atomization device.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] Please combine Figures 1-4The utility model embodiment provides an electronic atomization device 100, including casing 1 and setting in the atomization core subassembly 2 of casing 1, casing 1 is set up suction nozzle hole 11 on, atomization core subassembly 2 includes atomization pipe 21, and atomization pipe 21 includes the atomization part 211 of one side close to suction nozzle hole 11 and the liquid collection part 212 of one side away from suction nozzle hole 11, and the bottom wall of liquid collection part 212 is set up liquid collection groove 213, and the lateral wall of liquid collection part 212 is set up air inlet hole 214, and air inlet hole 214 is spaced apart with the bottom wall of liquid collection groove 213.

[0038] Understandably, atomization pipe 21 includes atomization part 211 and liquid collection part 212, atomization part 211 carries out atomization action, and the liquid collection groove 213 set up in the bottom of liquid collection part 212 collects condensed water that meets cold liquefaction in atomization pipe 21 and part of liquid that is not atomized, and air inlet hole 214 ensures that gas-liquid mixing is sufficient, improves atomization efficiency, and liquid collection groove 213 avoids liquid flow in atomization core subassembly 2.

[0039] Understandably, air inlet hole 214 is spaced apart with the bottom wall of liquid collection groove 213, keeps a certain distance between air inlet hole 214 and the bottom wall of liquid collection groove 213, prevents liquid from flowing back from air inlet hole 214, reduces liquid overflow, compared with the atomization channel 9 and air inlet hole setting of prior art upper and lower interval and axial parallel, air inlet hole 214 is set up in the side of atomization pipe 21 and is set up higher than the bottom wall of liquid collection groove 213, can effectively prevent liquid leakage, and air flows smoothly into atomization pipe 21, and air flow is optimized.

[0040] Specifically, air inlet hole 214 avoids directly facing the bottom wall of liquid collection groove 213, can form a certain inclination angle with the plane where the bottom wall of liquid collection groove 213 is located, reduces the possibility of condensate being sucked in, and improves atomization efficiency; the depth of liquid collection groove 213 is less than the lowest point height of air inlet hole 214, accommodates condensate while avoiding affecting air flow.

[0041] Optionally, a plurality of air inlet holes 214 spaced apart from the bottom wall of liquid collection groove 213 can be provided, as long as the smoothness of the air inlet channel can be ensured, and in the embodiment, the number of air inlet holes 214 is not specifically limited.

[0042] Further, the bottom of liquid collection groove 213 can be designed as an inclined surface to accommodate more condensate, and in some implementable schemes, the bottom of liquid collection groove 213 can also be provided with a liquid guide groove to facilitate the discharge of excess condensate and prevent condensate from flowing back.

[0043] Further, the atomization core subassembly 2 also includes absorbing cotton 22.

[0044] Further, please refer to Figure 3The outer surface of the side wall of the liquid receiving portion 212 is provided with an air inlet groove 215, and the air inlet groove 215 is provided with a notch 216 connected to the air inlet hole 214. The height H of the notch 216 (such as Figure 3 The height H) is higher than the lowest point of the air inlet 214 (as shown in FIG. Figure 3 As shown in h).

[0045] It can be understood that the height of the notch 216 is higher than the height of the lowest point of the air inlet 214. When the condensed water in the liquid collecting groove 213 overflows due to excessive or shaking, it will first flow to the absorbent cotton 22 through the low point of the air inlet 214, and will not flow into the air inlet groove 215 from the notch 216, thereby preventing the liquid from entering the air flow channel during inhalation and affecting the air intake, while reducing leakage.

[0046] Specifically, the air inlet groove 215 has an opening facing one side of the absorbent cotton 22. The air inlet groove 215 is set at the position corresponding to the air inlet hole 214. It can be set on the left and right sides of the air inlet hole 214 and connected to the air inlet hole 214 through the notch 216. The notch 216 is set at the top of the air inlet groove 215.

[0047] The length of the air inlet groove 215 corresponds to the height setting of the air inlet hole 214. It is necessary to ensure that the height of the top of the air inlet groove 215, that is, the notch 216, is higher than the lowest point of the air inlet hole 214. The shape of the air inlet groove 215 can be linear, curved or other suitable shapes, depending on the design requirements and aesthetic considerations, and is not specifically limited in this embodiment.

[0048] Furthermore, the absorbent cotton 22 is arranged close to the liquid receiving portion 212 , and a gap 23 is left between the absorbent cotton 22 and the liquid receiving portion 212 along the bottom wall surface of the liquid receiving portion 212 , and the gap 23 is connected to the air inlet 214 .

[0049] It can be understood that the gap 23 creates a space that allows the absorbent cotton 22 to have a certain buffer zone when it is subjected to external pressure, preventing the liquid in the absorbent cotton 22 (such as condensed water, un-atomized atomized liquid) from overflowing when squeezed, keeping the atomizing tube 21 dry and not soaked by liquid; at the same time, the gap 23 also plays the role of air guide, so that the air flow between the atomizing tube 21 and the absorbent cotton 22 is smoother, thereby improving the atomization efficiency; at the same time, the gap 23 also plays the role of air guide, so that the air flow between the atomizing tube 21 and the absorbent cotton 22 is smoother, thereby improving the atomization efficiency.

[0050] Specifically, the width of the gap 23 is sufficient to allow air to flow smoothly while preventing the liquid absorbed by the absorbent cotton 22 from flowing directly into the air inlet 214 through the gap 23; the gap 23 is formed by the space between the bottom wall of the liquid collecting part 212 and the absorbent cotton 22, and has a shape that matches the bottom wall of the liquid collecting part 212 and the top wall of the absorbent cotton 22.

[0051] Optionally, in one embodiment, the gap 23 is connected to the air inlet 214, but a certain degree of sealing must be ensured to prevent the infiltration of the atomized liquid. A sealing strip can be set around the gap 23 or other sealing measures can be adopted to ensure the airflow guiding function of the gap 23.

[0052] Further, see Figure 5 The absorbent cotton 22 is provided with an air intake opening 221 corresponding to the air intake groove 215 and connected to the air intake groove 215.

[0053] It can be understood that the air intake clearance port 221 provides a direct air guide channel to guide the air between the absorbent cotton 22 and the atomizing tube 21 to the air intake groove 215, thereby optimizing the air flow. By opening the corresponding air intake clearance port 221 on the absorbent cotton 22, it can also prevent the formation of negative pressure inside the absorbent cotton 22.

[0054] The absorbent cotton 22 is elastic and will deform to a certain extent when subjected to negative pressure, causing liquid to overflow. The air inlet 221 reduces the impact of negative pressure, provides an additional air channel, balances the air pressure inside the absorbent cotton 22, ensures a smoother and more uniform suction process, and reduces potential leakage problems.

[0055] Specifically, the air inlet opening 221 is arranged at a position corresponding to the air inlet groove 215 to ensure that air can flow unimpeded between the air inlet opening 221 and the air inlet groove 215 and enter the interior of the atomizer tube 21 through the air inlet hole 214; the shape of the air inlet opening 221 matches that of the air inlet groove 215 to maximize the air circulation area.

[0056] Further, see Figure 6 The bottom wall of the liquid collecting portion 212 is hollowed out with a wire post 217, which is spaced apart from the liquid collecting tank 213, and the height H1 of the wire post 217 (eg Figure 6 H1 shown in FIG) is higher than the height h1 of the liquid collecting tank 213 (as shown in FIG). Figure 6 h1).

[0057] It can be understood that the wire post 217 is spaced apart from the liquid collecting tank 213 to prevent the liquid in the liquid collecting tank 213 from overflowing or flowing to the wire post 217 for other reasons, and to prevent the wire post 217 from being in contact with the liquid for a long time. The wire post 217 is higher than the liquid collecting tank 213. The height difference promotes the upward flow of air, provides more guidance and support for the airflow inside the device, and improves the overall atomization performance.

[0058] Specifically, the wire post 217 is arranged on the bottom wall of the liquid collecting portion 212 and is sufficiently spaced apart from the liquid collecting tank 213 to avoid mutual influence. There can be multiple wire posts 217, each of which is provided with a wire for electrically connecting to the electronic components inside the atomizer tube 21.

[0059] Furthermore, the electronic atomization device 100 also includes a seal 3 and a microphone assembly 4 arranged on the side of the seal 3 away from the atomization core assembly 2. The seal 3 is provided with an air guide column 31 connected to the microphone assembly 4, and the air guide column 31 is connected to the air inlet 214.

[0060] It can be understood that the air guide column 31 is connected to the air inlet 214, which effectively prevents the liquid from flowing back to the microphone assembly 4 due to negative pressure changes or other reasons. Combined with the seal 3, the air guide column 31 can better maintain the internal air tightness and prevent leakage; and ensure smooth airflow, guide the air to better mix with the atomized liquid during the atomization process, adjust the inhalation resistance of the electronic atomization device 100, and increase the concentration and taste of the smoke.

[0061] Specifically, the diameter of the air guide column 31 is slightly smaller than the diameter of the air inlet 214 to prevent negative pressure from being generated during inhalation and to guide more air into the atomizer tube 21 from the air inlet 214. The air guide column 31 is arranged corresponding to the microphone assembly 4 and connects the microphone assembly 4 with the air inlet 214. The inner wall of the air guide column 31 has a smooth surface to reduce turbulence and airflow resistance.

[0062] The sealing member 3 is generally made of a soft material with good sealing performance, such as silicone or rubber, which can effectively prevent the leakage of the atomized liquid and fit tightly with the housing 1.

[0063] Furthermore, the electronic atomization device 100 further includes an isolation assembly 5 , which is movably mounted outside the atomization core assembly 2 . A liquid storage chamber 6 is formed between the isolation assembly 5 and the housing 1 , and the atomization portion 211 at least partially extends into the liquid storage chamber 6 .

[0064] It can be understood that the isolation component 5 controls the flow of the atomized liquid when subjected to force, effectively preventing leakage. When the isolation component 5 is forced to move toward the side away from the atomizer core component 2, at least a portion of the atomizing portion 211 is exposed, and the atomized liquid can enter the atomizer tube 21 for atomization.

[0065] Furthermore, the atomizing portion 211 partially extends into one side of the liquid storage chamber 6 , and a liquid inlet hole 2111 is provided on the atomizing portion 211 .

[0066] Specifically, the isolation assembly 5 includes an isolation piece 51 sleeved on the atomizer core assembly 2 and a lifting rod 52 connected to the breakpoint of the isolation piece 51. The lifting rod 52 extends from the nozzle hole 11, allowing the user to conveniently operate the lifting rod 52. Before use, the isolation piece 51 isolates the atomizer core assembly 2 from the liquid storage chamber 6 to prevent liquid from entering. When it is needed, the lifting rod 52 is pulled to drive the isolation piece 51 away from the original position, exposing the liquid inlet hole 2111 and communicating with the liquid storage chamber 6.

[0067] When the lifting rod 52 is subjected to excessive force, the breaking point will cause it to break at a preset breaking point, thereby preventing the isolation member 51 from being taken away from the interior of the electronic atomization device 100. At this time, the liquid inlet hole 2111 remains connected to the liquid storage chamber 6.

[0068] Furthermore, the electronic atomization device 100 further includes an oil seal 7 , which is disposed near the liquid storage chamber 6 . The oil seal 7 partially extends into the liquid storage chamber 6 and partially extends into the sealing member 3 to separate the liquid storage chamber 6 from the liquid receiving portion 212 .

[0069] It can be understood that the oil seal 7 seals the liquid storage chamber 6, isolates the liquid storage chamber 6 and the air inlet 214 on the liquid receiving portion 212, prevents the atomized liquid from entering the air inlet 214 from the liquid storage chamber 6, and reduces the risk of leakage. The oil seal 7 cooperates with the seal 3 to isolate the atomized liquid on the outside of the seal 3, effectively reducing the risk of leakage or spontaneous combustion; prevents the atomized liquid from entering the air inlet 214 from the liquid storage chamber 6, reduces the risk of leakage, enhances the air tightness of the equipment, prevents air from entering the liquid storage chamber 6 from places other than the atomizer core assembly 2, maintains the purity of the inhaled gas, and improves the overall smoke quality.

[0070] Specifically, the height of the portion of the oil seal 7 extending into the liquid storage chamber 6 is less than the height of the liquid inlet hole 2111, and the height of the portion extending into the seal 3 is greater than the height of the air inlet hole 214. This can effectively block the flow of liquid between the liquid storage chamber 6 and the liquid receiving portion 212 to avoid leakage, without hindering the atomized liquid from entering the atomizing portion 211 for atomization and the entry of air from the air inlet hole 214.

[0071] The oil seal 7 has a certain elasticity and thermal expansion adaptability, which improves the sealing performance and adapts to changes in air pressure and temperature to a certain extent.

[0072] Further, see Figure 7 The absorbent cotton 22 is arranged at the bottom of the sealing member 3, the air guide column 31 is arranged through the absorbent cotton 22, and the height H of the opening of the air guide column 31 toward the side of the atomizing core assembly 2 is 2( like Figure 7 As shown in H 2) Height h higher than the highest point of the absorbent cotton 22 2( like Figure 7 As shown in h 2) .

[0073] It can be understood that when the height of the air guide column 31 is higher than the highest point of the absorbent cotton 22, it can effectively prevent the liquid from flowing back from the absorbent cotton 22 to the air guide column 31. The air flow can pass through the air guide column 31 smoothly without being blocked by the absorbent cotton 22, and the absorption is evenly laid at the bottom of the seal 3 to ensure that the absorption capacity of condensed water is maximized.

[0074] Furthermore, an air guide channel 8 is formed between the seal 3 and the outer wall of the liquid receiving portion 212 . The atomizer core assembly 2 includes an atomization channel 9 connecting the atomization portion 211 and the liquid receiving portion 212 . The air guide channel 8 is in communication with the atomization channel 9 .

[0075] It can be understood that the air guide channel 8 is formed around the outer wall of the liquid receiving portion 212. When the user sucks through the mouthpiece hole 11, the surrounding air guide channel 8 helps to form a negative pressure in the atomization channel 9, thereby prompting the atomized liquid in the liquid storage chamber 6 to enter the atomization core assembly 2 through the liquid inlet hole 2111 faster, thereby promoting liquid supply.

[0076] Specifically, the air guide channel 8 is formed by the inner wall of the seal 3 and the outer wall of the liquid collecting part 212, and is a circular space. At this time, the air guide channel 8 can cover all ventilated places in the seal 3, including the air inlet port 221, the gap 23, and the connecting channel between the air guide column 31 and the air inlet hole 214. The air guide channel 8 in the seal 3 helps to optimize the airflow path and reduce the resistance of air adsorption while maintaining good sealing performance. The air guide channel 8 is connected with the atomization channel 9 to ensure that the airflow flows smoothly to the atomization part 211 to avoid airflow blockage. A sealing ring or silicone gasket can be used at the connection between the air guide channel 8 and the atomization channel 9 to prevent air leakage or liquid leakage.

[0077] Compared with the prior art, the electronic atomization device provided by the present invention has the following advantages:

[0078] The electronic atomization device provided in the embodiment of the present invention comprises an atomization tube comprising an atomization part and a liquid collecting part. The atomization part performs atomization, and a liquid collecting tank opened at the bottom of the liquid collecting part collects condensed water liquefied by cooling in the atomization tube and some un-atomized liquid. The air inlet hole ensures sufficient mixing of gas and liquid, thereby improving the atomization efficiency. The liquid collecting tank prevents the liquid from flowing in the atomization core assembly. At the same time, the air inlet hole and the bottom wall of the liquid collecting tank are spaced apart, and a certain distance is maintained between the air inlet hole and the bottom wall of the liquid collecting tank to prevent the liquid from flowing back from the air inlet hole and reduce liquid overflow. Compared with the existing atomization channel and air inlet hole settings that are spaced apart and parallel to the axis, the air inlet hole is opened on the side of the atomization tube and is higher than the bottom wall of the liquid collecting tank, which can effectively prevent liquid leakage. At the same time, air smoothly enters the atomization tube, thereby optimizing air flow.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
