[0035] The present utility model provides an electronic atomization device. Figure 1 It is a three-dimensional schematic diagram of an embodiment of the atomizer of the utility model. Figure 2 It is a cross-sectional schematic diagram of an embodiment of the atomizer of the utility model. Figure 3 for Figure 2 A magnified schematic diagram of center A.

[0036] The atomizer 100 includes an oil cup 110 and an atomizer assembly 120 located in the oil cup 110, the atomizer assembly 120 includes an outer tube 121 with an atomizer chamber 130 formed on the inner side, the oil cup 110 has an oil storage chamber 112 located outside the outer tube 121, the first end 1211 of the outer tube 121 is provided with a seal 140 for sealing the atomizer chamber 130 and the oil storage chamber 112, wherein the seal 140 includes a spacer 141 extending into the oil storage chamber 112 and forming a gap 190 with the outer wall of the outer tube 121, and the aerosol generating matrix in the oil storage chamber 112 enters the gap 190 under capillary action to form a liquid film layer.

[0037] In this embodiment, along the axial direction of the outer tube 121, an inlet 180 communicating with the gap 190 is formed between one end of the spacer 141 and the outer wall of the outer tube 121, and the size of the gap 190 does not change in the direction away from the inlet 180. For example, the length of the gap 190 along the axial direction of the smoke guide tube 111 is 1 mm, and the width is 0.15 mm. The spacer 141 with a constant size is relatively simple in design, low in manufacturing cost, and easy to implement.

[0038] Optionally, in some other embodiments, along the axial direction of the outer tube 121, an inlet communicated with the gap 190 is formed between one end of the spacer 141 and the outer wall of the outer tube 121, and the gap 190 gradually narrows in the direction away from the inlet. The gap 190 gradually narrows in the direction away from the inlet, and the flow of the aerosol generating substrate can be effectively controlled. As the gap 190 narrows, the flow velocity of the aerosol generating substrate therein slows down, so that the speed and amount of the aerosol generating substrate entering the atomizing chamber 130 can be better adjusted, and the stability and performance of the atomizer 100 are improved. As the gap 190 narrows, the surface tension of the aerosol generating substrate therein will increase. This helps to prevent the aerosol generating substrate from excessively entering the atomizing chamber 130, thereby reducing the leakage inside the atomizing chamber 130.

[0039] The oil storage chamber 112 stores an aerosol generating matrix, and a portion of the aerosol generating matrix enters the gap 190 under the capillary action. When the attraction of the inner wall of the gap 190 to the aerosol generating matrix in the gap 190 and the gravity of the aerosol generating matrix reach a balance, a stable liquid film layer structure is formed in the gap 190. The stable liquid film layer seals the gap 190 at the gap 190, which can prevent the aerosol generating matrix in the oil storage chamber 112 from entering the atomizing chamber 130 from the first end 1211 of the outer tube 121 and leaking outward, reducing the possibility of atomizer leakage, and can also help maintain the stability of the aerosol generating matrix supply in the atomizing assembly 120.

[0040] In some embodiments, the oil cup 110 includes a smoke guide tube 111 extending from the outer surface to the first end 1211 of the outer tube 121, and the seal 140 also includes a connecting portion 142 clamped between the inner wall of the outer tube 121 and the outer wall of the smoke guide tube 111, and the end of the connecting portion 142 facing the outside of the outer tube 121 is connected to the spacer 141.

[0041] In some embodiments, at least one first sealing unit 1421 is arranged on the outer circumferential surface of the connecting portion 142 along the axial direction of the outer tube 121, and each first sealing unit 1421 is interference fit with the inner wall of the outer tube 121. At least one second sealing unit 1422 is arranged on the inner circumferential surface of the connecting portion 142 along the axial direction of the smoke guide tube 111, and each second sealing unit 1422 is interference fit with the outer wall of the smoke guide tube 111. Such a double sealing structure can enhance the sealing inside the atomizer 100, reduce liquid leakage and gas escape, and ensure the stable operation of the atomizer 100. With the double sealing design, the structure of the atomizer 100 is more stable and can provide consistent performance under various conditions of use. It helps to prevent liquid leakage, reduce failure rate, and improve reliability and durability.

[0042] The first sealing unit 1421 and the second sealing unit 1422 are, for example, annular protrusion structures, or other structures as long as a better sealing effect can be achieved.

[0043] In some embodiments, at least part of the second sealing unit 1422 is staggered with the first sealing unit 1421. By staggering the second sealing unit 1422 and the first sealing unit 1421, a better advantage in the sealing effect can be obtained. This staggered setting can make the sealed part area larger, thereby improving the sealing performance of liquid and gas and reducing the possibility of leakage. The staggered sealing unit can effectively reduce the risk of air leakage and seepage. Under different use environment conditions, the staggered setting can provide a better sealing effect and stronger adaptability.

[0044] In some embodiments, the sealing member 140 further includes an abutting portion 143 connected between the spacer portion 141 and the connecting portion 142 , and the abutting portion 143 abuts against an end surface of the first end portion 1211 of the outer tube 121 .

[0045] In some embodiments, a conical structure 1431 is provided at one end of the abutment portion 143 axially away from the first end portion 1211 of the outer tube 121 . During the mutual insertion of the seal 140 and the smoke guide tube 111 , the conical structure 1431 guides the smoke guide tube 111 to the inside of the abutment portion 143 .

[0046] In some embodiments, the atomizer 100 further includes a sealing rod 150, which is inserted into the smoke guide tube 111 and extends into the atomization chamber 130, and the sealing member 140 further includes a protrusion 144 protruding toward the central axis of the outer tube 121 relative to the connecting portion 142, and the protrusion 144 is interference-fitted with the outer peripheral surface of the sealing rod 150. The sealing rod 150 is inserted into the smoke guide tube 111 and extends into the atomization chamber 130, and the protrusion 144 is interference-fitted with the outer peripheral surface of the sealing rod 150, which can effectively enhance the sealing performance. This structure can reduce the leakage of the aerosol generating substrate and ensure the stable operation of the atomizer 100.

[0047] The embodiment of the utility model also provides an electronic atomization device, which includes a power supply device and an atomizer 100 as any of the above embodiments, and the atomizer 100 is installed on the power supply device. The atomizer 100 includes an oil cup 110 and an atomization assembly 120 located in the oil cup 110, the atomization assembly 120 includes an outer tube 121 with an atomization cavity 130 formed inside, the atomization assembly 120 also includes an inner tube 123 and an atomization core 124, the atomization core 124 includes an oil guide and a heating element, the heated aerosol generation matrix is ​​mixed with air in the atomization cavity 130 to form an inhalable aerosol, the inner tube 123 and the outer tube 121 are also provided with an oil guide hole 125, the oil cup 110 has an oil storage cavity 112 located outside the outer tube 121, and the first end 1211 of the outer tube 121 is provided with a sealing member 140 for sealing the atomization cavity 130 and the oil storage cavity 112. The oil storage chamber 112 is also provided with a base 160 and a connector 170, and an air inlet 161 is also provided on the base 160. The sealing rod 150 cooperates with the connector 170 to seal the air inlet 161. In use, gas enters from the air inlet 161, mixes with the aerosol in the atomizing chamber 130, and is then sucked out from the smoke guide pipe 111.

[0048] According to the electronic atomization device of the embodiment of the utility model, the atomizer includes a seal 140 provided at the first end of the outer tube 121, and the seal 140 seals and separates the atomization chamber 130 from the oil storage chamber 112. The seal 140 includes a spacer 141 extending in the oil storage chamber 112 and forming a gap 190 with the outer wall of the outer tube 121. The oil storage chamber 112 stores an aerosol generating matrix, and a part of the aerosol generating matrix is ​​in the gap 190 under the capillary action. When the attraction of the inner wall of the gap 190 to the aerosol generating matrix in the gap 190 reaches a balance with the gravity of the aerosol generating matrix, a stable liquid film layer structure is formed in the gap 190. The stable liquid film layer seals the gap 190 at the above-mentioned gap 190, which can prevent the aerosol generating matrix in the oil storage chamber 112 from entering the atomization chamber 130 from the first end of the outer tube 121 and leaking outward, thereby reducing the possibility of atomizer leakage and helping to maintain the stability of the aerosol generating matrix supply in the atomization assembly 120.
