[0042] In order to have a clearer understanding of the technical features, objects and effects of the application, the specific embodiments of the application will be described in detail with reference to the drawings.

[0043] Figure 1Some preferred embodiments of the electronic atomization device of the present application are shown. The electronic atomization device can be used to heat and atomize liquid atomization medium to generate atomized gas for a user to inhale. In some embodiments, the electronic atomization device has the advantages of being not easy to leak liquid, simple structure, and good atomization taste.

[0044] As shown in Figure 1 some embodiments, the electronic atomization device includes an atomizer A and a power supply assembly B; the atomizer A can be used to atomize atomization medium, and the atomizer A has a straight-through air outlet structure. The power supply assembly B can be mechanically and electrically connected with the atomizer A, and can be used to supply power to the atomizer A.

[0045] As shown in Figures 2-3 some embodiments, further, the atomizer A includes an atomization shell 10 and an atomization assembly 20. The atomization shell 10 is sleeved on the periphery of the atomization assembly 20, and is used to accommodate the atomization assembly 20 and store liquid atomization medium. The atomization assembly 20 can be accommodated in the atomization shell 10, and is used to heat and atomize liquid atomization medium.

[0046] Further, in some embodiments, the atomization shell 10 can include a shell body 11 and an air outlet tube 12 arranged in the shell body 11. The air outlet tube 12 can be located at the central axis of the shell body 11, and the gap between the air outlet tube 12 and the inner side wall of the shell body 11 can form a liquid storage cavity 13 for storing liquid atomization medium. The air outlet tube 12 is a hollow structure with both ends penetrating through, and the inner side can form an air outlet channel 121. The air outlet channel 121 is arranged at the central axis of the atomization shell 10, extends along the axial direction of the atomization shell 10, and communicates with the cavity 2271. The air outlet channel 121 is straight through the cavity 2271.

[0047] As shown in Figure 4 and Figure 5 some embodiments, further, the atomization assembly 20 includes an atomization base 21, an atomization seat 22, and a heating assembly 23. The atomization base 21 can be used to support the heating assembly 23, and in other embodiments, the atomization base 21 can be omitted. The atomization seat 22 is sleeved on the atomization base 21 and detachably assembled with the atomization base 21. The heating assembly 23 is accommodated in the atomization seat 22, and is used to heat liquid atomization medium transmitted from the liquid storage cavity 13.

[0048] As shown in Figure 6As shown, further, in some embodiments, the atomizing base 21 comprises a base body 211, an air inlet column 212, and an annular cavity 213. In some embodiments, the base body 211 is configured to cooperate with the atomizing seat 22 and can seal the opening 111 at the lower portion of the atomizing shell 10. The air inlet column 212 can be protrudingly arranged in the base body 211 and configured to allow external air to enter the atomizing assembly 20. The annular cavity 213 is arranged in the base body 211 and located at the outer periphery of the air inlet column 212.

[0049] In some embodiments, the base body 211 comprises a bottom wall 2111 and a peripheral wall 2112. The bottom wall 2111 can be substantially elliptical. The peripheral wall 2112 can be arranged on the bottom wall 2111 and configured to surround the bottom wall 2111 along the circumferential direction of the bottom wall 2111 to form the annular cavity 213. The peripheral wall 2112 can be provided with an extension protrusion 2113. There can be two extension protrusions 2113 arranged at two opposite sides of the peripheral wall 2112. Specifically, the two extension protrusions 2113 can be located at the two ends of the major axis of the bottom wall 2111. Each extension protrusion 2113 can be configured to be clamped with the atomizing seat 22. Specifically, each extension protrusion 2113 can be provided with a clamping hole 2114, and the extension protrusion 2113 can be clamped with the atomizing seat 22 through the clamping hole 2114.

[0050] In some embodiments, the air inlet column 212 is protrudingly arranged on the bottom wall 2111 towards the inner side of the seat body 211 and is located at the center of the seat body 211. The air inlet column 212 is a hollow structure and an air inlet channel 2120 can be formed inside. The atomization base 21 is provided with an air inlet hole 2121, which is arranged on the air inlet column 212, located at one end of the air inlet column 212 and in communication with the air inlet channel 2120. The air inlet hole 212 can be arranged towards the heating assembly 23 for external gas to enter the atomization cavity 220. In some embodiments, the height of the air inlet hole 2121 is higher than the height of the bottom wall 2111, and the air inlet hole 2121 can be one or more. When the liquid in the atomization seat 22 flows downward, if the liquid leaks from the bottom end of the heating assembly 23, it will flow into the liquid storage groove 215 in the ring cavity 213 due to the surface tension of the liquid. In some embodiments, the air inlet hole 2121 can be arranged directly opposite to the heating assembly 23 and is spaced apart from the heating assembly 23, and the space therebetween can form a cavity. By spacing the air inlet hole 2121 and the heating assembly 23, the liquid can be prevented from leaking directly from the air inlet hole 2121. In some embodiments, the distance D between the air inlet hole 2121 and the heating assembly 23 can be 0.5mm-8mm. Due to the surface tension of the liquid, the liquid cannot leak directly from the air inlet hole 2121 but flows into the liquid storage groove 215 along the side wall of the air inlet column 212. If the distance between the air inlet hole 2121 and the heating assembly 23 is less than 0.5mm, the liquid will leak directly from the air inlet hole. If the distance between the air inlet hole 2121 and the heating assembly 23 is greater than 8mm, the gravity can be greater than the surface tension, and the liquid will also leak directly from the air inlet hole 2121. In some embodiments, the liquid can be condensed liquid formed after heating and atomization or atomized liquid (liquid atomized medium) leaked from the liquid storage cavity 13.

[0051] Further, the atomization seat 22 further comprises mounting columns 214, which can be protrudingly arranged on the bottom wall 2111, and the mounting columns 214 are two, which are arranged on the two opposite sides of the air inlet column 212. In some embodiments, the height of the mounting column 214 can be higher than that of the air inlet column 212 for mounting the conductive member 26, which is arranged one by one with the conductive member 26. By arranging the height of the mounting column 214 to be higher than that of the air inlet column 212, the conductive member 26 in the mounting column 214 can support the heating assembly 23 and space the heating assembly 23 and the air inlet hole 2121.

[0052] Furthermore, in some embodiments, the atomizing base 21 is provided with a liquid storage tank 215; the liquid storage tank 215 is disposed on the inner side of the bottom wall 2111 and the peripheral wall 2112. In some embodiments, the liquid storage tank 215 may also be disposed on the outer side of the mounting column 214 and the air intake column 212. In some embodiments, there are multiple liquid storage tanks 215 on the bottom wall 2111, which can be arranged side by side along the long axis of the bottom wall 2111, and each liquid storage tank 215 can extend along the short axis parallel to the bottom wall 2111. There can also be multiple liquid storage tanks 215 on the peripheral wall 2112, which can be arranged circumferentially at intervals along the peripheral wall 2112 and extend longitudinally to the bottom wall 2111. There are also multiple liquid storage tanks 215 on the mounting column 214 and the air intake column 212, which can be arranged at circumferential intervals along the mounting column 214 and the air intake column 212, and each liquid storage tank 215 can extend axially to the bottom wall 2111. In some embodiments, the liquid storage tank 215 can absorb and store leaked liquid through capillary adsorption.

[0053] like Figure 7 and Figure 8 As shown, further, in some embodiments, the atomizing base 22 is a cylindrical structure. Specifically, in some embodiments, the atomizing base 22 is a cylindrical structure with an approximately elliptical cross-section. The atomizing base 22 includes an atomizing cavity 220, an end wall 229, a side wall 221, and a positioning portion 222. One end of the side wall 221 is connected to the end wall 229 and extends downward, and the lower part of the side wall 221 can surround and form the atomizing cavity 220. The side wall 221 may include an extension portion 2211; the extension portion 2211 can be used to cooperate with the atomizing base 21 for installation. In some embodiments, the outer wall surface of the extension portion 2211 may be provided with a hook 2212, and the extension portion 2211 can be engaged with the atomizing base 21 through the hook 2212. Specifically, it can be engaged with the snap hole 2114 on the atomizing base 21. The atomizing cavity 220 can be provided for the heating element 23, providing an atomization space for the heating element 23 to atomize the liquid atomizing medium. The positioning part 222 can be connected to the end wall 229 and extends downward into the atomizing chamber 220 for positioning and installing the heating element 23. In some embodiments, the positioning part 222 includes a positioning groove 2221, a top wall 2222, and an atomizing hole 2223. The opening of the positioning groove 2221 can face the atomizing base 21 and communicate with the atomizing chamber 220. During installation, the heating element 23 can be partially inserted into the positioning groove 2221. The top wall 2222 is located above the positioning groove 2221. The atomizing hole 2223 can be disposed on the top wall 2222 and communicate with the positioning groove 2221, and thus communicate with the atomizing chamber 220.

[0054] Further, in some embodiments, the atomization seat 22 further comprises an inner sleeve 223, which can be mounted at the lower portion of the atomization cavity 220 and is a through-cylindrical structure. The inner sleeve 223 can be coaxially arranged with the positioning portion 222 and oppositely arranged with the positioning portion 222. The inner sleeve 223 can be connected with the inner wall surface of the side wall 221 and integrally formed with the side wall 221. The inner sleeve 223 is spaced apart from the positioning portion 222, and the space can form a liquid inlet hole 2231 for the liquid in the liquid outlet hole 225 to flow onto the heating assembly 23.

[0055] Further, in some embodiments, the atomization seat 22 further comprises an airflow through hole 224, which is arranged on the end wall 229 and located at the central axis of the end wall 229, and oppositely arranged with the atomization hole 2223. The center of the airflow through hole 224 can be coaxially arranged with the center of the atomization hole 2223, and the aperture of the airflow through hole 224 is larger than the aperture of the atomization hole 2223. In turn, the atomized gas formed by the atomization cavity 223 can be output to the air outlet channel 121 from the airflow through hole 224. In some embodiments, one end of the airflow through hole 224 can be in communication with the air outlet channel 121; the other end can be in communication with the cavity 2271 of the liquid leakage prevention structure 227. Specifically, one end of the air outlet tube 12 is inserted into the airflow through hole 224, so that the air outlet channel 121 and the airflow through hole 224 are in communication, and a straight-through air outlet structure is formed.

[0056] Further, in some embodiments, the atomization seat 22 further comprises a liquid outlet hole 225, which can be two. The two liquid outlet holes 225 can be arranged at two opposite sides of the airflow through hole 224 and arranged side by side with the airflow through hole 224. The liquid outlet hole 225 can extend downward along the axial direction of the atomization seat 22 and be in communication with the liquid inlet hole 2231. The liquid outlet hole 225 can be in communication with the liquid storage cavity 13 for outputting the liquid atomization medium in the liquid storage cavity 13 to the heating assembly 23.

[0057] Further, in some embodiments, the atomizing seat 22 further comprises a gas-liquid balance structure 226, which can be arranged on the side wall 221 and used for absorbing liquid and balancing the air pressure of the liquid storage cavity 13. In some embodiments, the gas-liquid balance structure 226 can comprise liquid-absorbing and air-exchanging grooves 2261, air-exchanging holes 2263 and a communication hole 2262. The liquid-absorbing and air-exchanging grooves 2261 can be arranged side by side along the axial direction of the atomizing seat 22, and each of the liquid-absorbing and air-exchanging grooves 2261 can extend along the circumferential direction of the atomizing seat 22. Two adjacent liquid-absorbing and air-exchanging grooves 2261 are arranged in communication with each other. The liquid-absorbing and air-exchanging grooves 2261 can absorb liquid by capillary action, and at the same time, can allow air to flow through, so as to exchange air for the liquid storage cavity 13, thereby balancing the air pressure of the liquid storage cavity 13, facilitating the liquid atomizing medium in the liquid storage cavity 13 to flow out from the liquid outlet hole 225. In some embodiments, the liquid-absorbing and air-exchanging grooves 2261 can be one, and can be limited to be multiple. The communication hole 2262 is arranged on the side wall 221 and located at the upper portion of the side wall 221, and used for communicating the air-exchanging hole 2263 and the liquid-absorbing and air-exchanging grooves 2261. In some embodiments, the air-exchanging hole 2263 is arranged on the end wall 229 and arranged along the axial direction, one end of which is in communication with the liquid storage cavity 13, and the other end is in communication with the communication hole 2262.

[0058] Further, in some embodiments, the atomizer further comprises a liquid leakage prevention structure 227, which can be arranged on the atomizing seat 22 and located between the heating assembly 23 and the air outlet channel 121, and used for preventing liquid from flowing out of the atomizing shell 10. In some embodiments, the liquid can be condensate formed by heating and atomizing the atomizing gas or atomizing liquid (liquid atomizing medium) leaked from the liquid storage cavity 13.

[0059] Further, in some embodiments, the liquid leakage prevention structure 227 includes a cavity 2271, a liquid output channel 2272, and a liquid absorbing member 2273. The cavity 2271 is arranged in the atomization seat 22 and is located at an end of the airflow passage hole 224 away from the air outlet channel 121 and directly communicates with the air outlet channel 121, so that the cavity 2271 is arranged between the heating assembly 23 and the air outlet channel 121. Specifically, the cavity 2271 can be arranged between the airflow passage hole 224 and the atomization hole 2223. The cavity 2271 can communicate with the airflow passage hole 224 and the atomization hole 2223. The liquid output channel 2272 is arranged on the atomization seat 22, specifically, it can be arranged on the side wall 221 and communicates with the cavity 2271 and the air-liquid balance structure 226, for outputting the liquid leakage in the cavity 2271 to the air-liquid balance structure 226. The liquid absorbing member 2273 is arranged on at least one side of the cavity 2271 and absorbs and stores liquid through capillary adsorption. Specifically, the liquid absorbing member 2273 can be arranged on the bottom surface of the cavity 2271 (i.e., arranged on the side of the top wall 2222 opposite to the positioning groove 2221), of course, it can be understood that in other embodiments, the liquid absorbing member 2273 is not limited to be arranged on the bottom surface of the cavity 2271, it can be arranged on other surfaces of the cavity 2271, and the cavity 2271 can not be limited to have only one surface arranged with the liquid absorbing member 2273. In some embodiments, the liquid absorbing member 2273 can be omitted.

[0060] Further, in some embodiments, the cavity 2271 is located at the central axis of the atomization seat 22, and the height H of the cavity 2271 can be between 0.5 mm and 5 mm. If the height of the cavity 2271 is less than 0.5 mm, a through groove cannot be formed to communicate the airflow passage 228 and the airflow passage hole 224, and if the height is greater than 5 mm, the atomization gas cannot be concentrated, reducing the smoking experience.

[0061] Further, in some embodiments, the liquid output channel 2272 includes a through hole 227a which is opened on the side wall 221 and communicates with the liquid absorbing and air exchanging groove 2261, so that the liquid in the cavity 2271 can flow out to the liquid absorbing and air exchanging groove 2261 through the through hole 227a and be stored on the liquid absorbing and air exchanging groove 2261. It can be understood that in some embodiments, the liquid output channel 2272 is not limited to be a through hole 227a. In some embodiments, the through hole 227a can be two, which can be symmetrically arranged on two opposite sides of the cavity 2271, specifically, it can be located at the two ends of the short axis of the atomization seat 22, of course, it can be understood that in other embodiments, the through hole 227a can not be limited to two.

[0062] Further, in some embodiments, the liquid absorption member 2273 can include a plurality of liquid absorption grooves 2274 arranged side by side, which can be capillary grooves capable of absorbing liquid by capillary action so that a liquid film is formed thereon, thereby achieving the effect of storing liquid and preventing liquid leakage. In some embodiments, the liquid absorption grooves 2274 can not be limited to a plurality, and in other embodiments, the liquid absorption grooves 2274 can also be one.

[0063] Further, in some embodiments, the atomizing seat 22 further includes an airflow channel 228 arranged on the sidewall 221 in the axial direction of the atomizing seat 22 and in communication with the cavity 2271 and the atomizing base 21, in particular, in communication with the liquid output channel 2272, thereby in communication with the cavity 2271, so that the air pressure at the cavity 2271 is greater than the pressure of the atomizing base 21, and the leaked liquid is more likely to flow from the cavity 2271 to the atomizing base 21, thereby being present in the liquid absorption groove 2274.

[0064] When the user stops inhaling, the negative pressure in the air outlet channel 121 is removed, and the condensed liquid in the air outlet channel 121 flows downward along the air outlet channel 121. Since the cavity 2271 is present and the cavity 2271 has a through hole, the condensed liquid can be stored in the atomizing seat 22 through the cavity 2271; preferably, stored in the liquid absorption and air exchange groove 2261 of the atomizing seat 22; the condensed liquid can be absorbed by the liquid absorption and air exchange groove 2261 of the atomizing seat 22 by capillary force, thereby preventing the condensed liquid from flowing out of the atomizing shell 10.

[0065] During transportation and storage, due to the temperature, air pressure and mechanical vibration of the outside world, the atomizing liquid can leak from the porous pores of the porous body 231 to the atomizing hole 2223 through the liquid outlet hole 225, and the atomizing liquid stored in the atomizing hole 2223 can also be stored in the liquid absorption and air exchange groove 2261 of the atomizing seat 22 through the cavity 2271 when flowing upward.

[0066] Again Figure 5As shown, further, in some embodiments, the heating assembly 23 can include a porous body 231, which can be a ceramic porous body. Understandably, in other embodiments, the porous body 231 is not limited to be a ceramic porous body, but can be liquid-absorbing cotton or the like. The porous body 231 can be in a columnar shape, and the porous body 231 is provided with a central through hole 2311 in the axial direction, which is in communication with the atomizing hole 2223 and the air inlet hole 2121, i.e., the central through hole 2311 can be straight through the air outlet channel 121 for the gas in the air inlet hole 2121 to carry out the atomized gas formed by atomizing the liquid atomizing medium by the heating body 232 from the atomizing hole 2223. In some embodiments, the liquid leakage prevention structure 227 can be arranged at one end of the central through hole 2311 opposite to the air outlet channel 121, i.e., at the atomizing hole 2223. The heating body 232 can be a sheet-shaped heating body, which can be arranged in the central through hole 2311 and fixed to the inner wall of the porous body 231 for heating the liquid atomizing medium on the porous body 231. In other embodiments, the heating assembly 23 is not limited to include the porous body 231, and in this embodiment, the heating body 232 can be a mesh heating net; the heating assembly 23 further includes a heating seat, which can be detachably assembled with the atomizing seat 22, and the heating seat can be clamped into the atomizing seat 22 from one side of the atomizing seat 22 and is provided with a central through hole for the gas flow to pass through. In this embodiment, the liquid leakage prevention structure 227 is arranged on the heating seat and the atomizing seat 22 and located between the heating assembly 23 and the air outlet channel 121, and specifically, the cavity 2271 is located on the heating seat and the atomizing seat 22 and at one end of the gas flow through hole 224.

[0067] Further, in some embodiments, the atomizing assembly 20 further includes a first sealing sleeve 24, which can be sleeved on the heating assembly 23 and can be partially mounted into the positioning groove 2221 and the inner sleeve 223 for fixing the heating assembly 23 and sealing the gap between the positioning groove 2221, the inner sleeve 223 and the heating assembly 23. The first sealing sleeve 24 includes a sleeve body 241, which is a hollow structure, and the side surface of the sleeve body 241 is provided with a first avoiding hole 242 corresponding to the liquid inlet hole 2231 so as to facilitate the liquid in the liquid outlet hole 225 to enter the liquid inlet hole 2231. The top of the sleeve body 241 can be provided with a second avoiding hole 243, which can be arranged in the axial direction and corresponds to the atomizing hole 2223 so as to facilitate the atomized gas formed by atomizing the liquid atomizing medium by the heating assembly 23 to be output from the atomizing hole 2223.
