Description

Technical Field

[0001] The present invention relates to an atomization device, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] Electronic cigarettes, also known as virtual cigarettes or electronic atomizing devices, are used as an alternative to cigarettes, often for smoking cessation. They resemble cigarettes in appearance and flavor, but generally do not contain the tar, particulate matter, and other harmful ingredients found in cigarettes.

[0003] In current electronic atomization devices, if the e-liquid is not completely atomized during heating, during the process of inhalation, as the number of puffs increases, some condensed droplets or liquid surface will be produced on the side walls of the airflow channel. The produced droplets can easily be carried out with subsequent puffs, thus giving consumers a bad user experience, and the formed liquid surface will block the output of smoke. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that, in view of the defect that the smoke liquid in the electronic atomization device in the prior art is not completely atomized when heated, condensation occurs during use due to condensation, which easily causes leakage during suction, an atomizer and an electronic atomization device are provided.

[0023] The liquid absorption structure is arranged in the air outlet channel and has a plurality of liquid storage tanks arranged circumferentially.

[0028] Preferably, in the electronic atomization device described in the present invention, the liquid absorption structure is arranged directly above the atomization component.

[0029] By implementing the present invention, the following beneficial effects are achieved:

[0030] The present invention provides a liquid absorption structure in the air outlet channel, and a plurality of liquid storage tanks are arranged around the liquid absorption structure. The liquid storage tanks can absorb the condensed liquid in the air outlet channel through capillary force, so that the condensed liquid and / or the smoke liquid that is not completely atomized generated during the suction process are retained in the liquid storage tank, forming a liquid film in the liquid storage tank, and then can be stored in the liquid storage tank, thereby preventing the user from sucking and leaking during the suction process, and improving the user experience.

[0031] Moreover, the liquid absorption structure includes a plurality of fins, which are arranged in parallel and spaced apart in the longitudinal direction. A liquid storage tank can be formed between each two adjacent fins. The smoke generated during the suction process will be retained in the liquid storage tank due to the liquid droplets brought out by the fin structure.

The reflux groove is used to allow the liquid to flow back to the atomizer core along the reflux groove to be atomized again when excessive liquid is accumulated in the liquid storage tank.

[0033] In order to allow the refluxed smoke liquid to be better absorbed by the atomizer core and re-atomized, the length of the fin at the bottom of the liquid absorption structure extending to the central axis of the liquid absorption structure is shorter than the length of the adjacent fin extending to the central axis.

[0034] In addition, when the e-cigarette is heated, due to the presence of oil film in the atomization, the bubbles generated during the atomization process can easily bring out the incompletely atomized smoke liquid. When the smoke rises, the liquid absorption structure directly above the atomization core absorbs the droplets carried in the smoke and stores them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0053] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0054] Orientation Definitions: The orientations shown in the accompanying drawings are the upper, lower, top, and bottom orientations of the present invention. It should be understood that the orientations or positional relationships indicated by "upper" and "lower" are based on the orientations or positional relationships shown in the accompanying drawings and are constructed and operated in specific orientations. They are merely for the purpose of facilitating the description of the present technical solution and do not require the devices or components indicated to have specific orientations. Therefore, they should not be construed as limitations on the present invention.

[0055] Figures 1 to 4 The first embodiment of the electronic atomization device of the present invention is shown. The electronic atomization device is used for atomizing liquid media such as atomized cigarette liquid and medicine, and includes an atomizer and a power supply device mechanically and electrically connected to the atomizer. The atomizer is used to heat and atomize the liquid medium, and the power supply device is used to supply power to the atomizer. Preferably, the atomizer and the power supply device are detachably connected. The power supply device includes a power supply housing, a battery arranged in the power supply housing, a conductive contact arranged in the power supply housing and connected to the battery and the atomizer, and a control circuit arranged in the power supply housing and electrically connected to the battery and the atomizer.

[0056] like Figures 3 to 7As shown, in this embodiment, the atomizer includes a shell 10; a base 20, an atomizer assembly 30, a first sealing member 40, a gas-liquid balance element 50, and a liquid guide element 60. The shell 10 is sleeved on the periphery of the atomizer assembly 30, and its inner side is used to form a liquid storage chamber 111 for accommodating a liquid medium. In this embodiment, the liquid medium is tobacco oil. The base 20 is for mounting the atomizer assembly 30, and the shell 10 is sleeved on the base 20. The atomizer assembly 30 is arranged in the shell 10 and is located on the base 20. The first sealing member 40 is arranged on the base 20, and is used to seal the connection between the atomizer assembly 30 and the base 20. The gas-liquid balance element 50 is arranged in the body 11 and is located at the lower part of the liquid storage chamber 111. It is sleeved on the periphery of the atomizer assembly 30 and is located on the base 20. The gas-liquid balancing element 50 connects the liquid storage chamber 111 with the outside world, thereby balancing the gas pressure in the liquid storage chamber 111. There may be two liquid-guiding elements 60. It is understood that in other embodiments, there may be one or more liquid-guiding elements 60. The liquid-guiding element 60 is disposed in the gas-liquid balancing element 50 and is used to connect the liquid storage chamber 111 with the atomizing assembly 30 through liquid conduction, thereby supplying liquid medium to the atomizing assembly 30. It is understood that in other embodiments, both the gas-liquid balancing element 50 and the liquid-guiding element 60 may be omitted.

[0057] Furthermore, in this embodiment, the housing 10 includes a main body 11 and an air outlet pipe 12; the main body 11 and the air outlet pipe 12 are integrally formed by injection molding. It is understandable that in some other embodiments, the air outlet pipe 12 and the main body 11 form a split structure. The main body 11 is sleeved on the base 20 and the atomizer assembly 30, and a space is left between it and the upper part of the atomizer assembly 30, and the space is used to form the liquid storage chamber 111. The air outlet pipe 12 is arranged in the main body 11 along the longitudinal direction, and is connected to the atomizer assembly 30. The air outlet pipe 12 is located at the central axis of the main body 11. It is understandable that in some other embodiments, the air outlet pipe 12 is arranged on one side of the main body 11, not limited to the central axis, and the air outlet pipe 12 can also be arranged at an angle. The inner side of the air outlet pipe 12 forms an air outlet channel 121, and the air outlet channel 121 is arranged along the axial direction of the air outlet pipe 12, and its side wall is integrally formed with the housing. When the user inhales, the atomized gas can reach the user's mouth through the air outlet channel 121. The second end 1212 of the air outlet channel 121 is inserted into the atomizer assembly 30, and its first end 1211 forms a mouthpiece for the user to inhale the atomized gas. At least one first liquid absorption groove 122 is provided on the inner side wall of the air outlet channel 121; in this embodiment, the at least one first liquid absorption groove 122 can be a plurality of first liquid absorption grooves 122; it can be understood that in some other embodiments, the number of the first liquid absorption groove 121 is not limited to a plurality, and it can also be one. The first liquid absorption groove 122 has a capillary effect, which is used to absorb the condensate formed by condensation on the side wall of the air outlet channel 121, and the condensate flows to the atomizer assembly 30 under the action of gravity, and the atomizer assembly 30 re-atomizes the condensate flowing down the first liquid absorption groove 122, thereby improving the utilization rate of the liquid medium.

[0058] Furthermore, in this embodiment, the plurality of first liquid absorption grooves 122 are disposed on the inner sidewall of the outlet pipe 12 and are spaced apart circumferentially along the outlet channel 121. When the atomized gas passes through the outlet channel 121 and reaches the outlet, the airflow around the outlet channel 121 condenses against the inner sidewall of the outlet pipe 12, forming condensate. At this time, the first liquid absorption grooves 122 can absorb the condensate into the grooves through capillary action. In this embodiment, the first liquid suction groove 122 is arranged along the longitudinal direction of the air outlet channel 121 and extends from the second end 1212 of the air outlet channel 121 toward the first end 1211 of the air outlet channel 121. It is parallel to the central axis of the air outlet channel 121 and is connected to the atomizing assembly 30 in the atomizing assembly 30 so that the condensed liquid flows along the direction of the first liquid suction groove 122 to the top of the atomizing assembly 30 under the action of gravity, and drips onto the atomizing assembly 30 to be atomized again, thereby improving the utilization rate of the liquid medium and preventing the liquid medium from being sucked into the user's mouth, thereby improving the user experience. In this embodiment, the first liquid suction groove is not limited to being arranged longitudinally, and it can be arranged in a spiral or inclined manner.

[0059] In this embodiment, an outlet 1221 is provided on the end surface of the first end 1211 of the air outlet channel 121. The outlet 1221 is connected to the first liquid suction groove 122 and to the atomization component 30. Through the outlet 1221, the liquid in the first liquid suction groove 122 can drip onto the atomization component 30.

[0060] In this embodiment, the depth of the first liquid absorption trough 122 gradually decreases as it moves away from the outlet 1221, and the bottom surface of the first liquid absorption trough 122 is a sloped surface inclined toward the outlet 1221. This results in a smaller amount of liquid being stored in the upper portion of the first liquid absorption trough 122 and a larger amount in the lower portion, thereby preventing the liquid in the upper portion of the first liquid absorption trough 122 from being aspirated into the user's mouth. By configuring the bottom surface of the first liquid absorption trough 122 as a sloped surface inclined toward the outlet 1221, the resistance to aspiration of the lower portion of the liquid is increased, thereby preventing the liquid from being aspirated into the user's mouth. Specifically, in this embodiment, the depth of each first liquid absorption trough 122 may be greater than or equal to 0.1 mm. In this embodiment, the width of each first liquid absorption trough 122 gradually increases along the opening direction of the first liquid absorption trough 122, resulting in the first liquid absorption trough 122 having a narrow interior and a wide opening, thereby facilitating the flow of liquid along the first liquid absorption trough 122 to the atomizer assembly 30. In this embodiment, the width of each first liquid suction groove 122 may be 0.05-1 mm.

[0061] like Figures 4 to 8 As shown, further, in this embodiment, the base 20 includes a base body 21, a support assembly 22 provided on the base body 21, and a liquid storage structure 23; the shape and size of the cross section of the base body 21 are adapted to the shape and size of the open end of the housing 10, and is used to block the opening of the housing 10. A groove 211 is provided on the base 20; specifically, the groove 211 is provided on a side of the base body 21 opposite to the atomizing chamber 311 of the atomizing assembly 30, and facilitates the formation of the liquid storage structure 23 at the bottom of the atomizing chamber 311; the support assembly 22 includes two groups of support columns arranged at intervals; the two groups of support columns are respectively located on two opposite sides of the groove 211, and are used to support the atomizing element 32 in the atomizing assembly 30. The liquid storage structure 23 is provided in the groove 211 and is connected to the atomizing chamber 311 of the atomizing assembly 30, and is used to store liquid medium to prevent the liquid medium from leaking.

[0062] Furthermore, in the present embodiment, the liquid storage structure 23 includes a plurality of second liquid absorption grooves 231, a diverter groove 232, and a plurality of guide grooves 233. The plurality of second liquid absorption grooves 231 are arranged side by side and at intervals at the bottom of the groove 211, and the second liquid absorption groove 231 is arranged relative to the atomizing chamber 311, and has a capillary action, which can absorb the liquid medium dripping from the atomizing chamber 311 or from the air outlet channel 121. The number of the second liquid absorption grooves 231 is not limited to multiple, and it can be one. The diverter groove 232 is located on the bottom surface of the groove 211, and it is intersected with the plurality of second liquid absorption grooves 231, cross-cutting the second liquid absorption groove 231, and communicating with the second liquid absorption groove 231, and is used for diversion, so as to facilitate faster absorption of the liquid medium. The multiple guide grooves 233 are arranged at intervals on the side wall of the groove 211. They are arranged corresponding to the second liquid suction groove 231 and the diversion groove 232, and are connected to the second liquid suction groove 231 and the diversion groove 232. They have a capillary effect and are used to pour liquid into the second liquid suction groove 231.

[0063] Furthermore, in this embodiment, each second liquid absorption groove 231 is arranged to extend laterally along the bottom surface of the groove 211, that is, to extend laterally along the atomization chamber 311, which controls the flow direction of the liquid medium, thereby effectively preventing leakage. In this embodiment, the groove width of the second liquid absorption groove 231 is 0.05-1mm, and in this embodiment, the groove depth of each second liquid absorption groove 231 is greater than 0.1mm. It can be understood that in some other embodiments, the groove depth of the second liquid absorption groove 231 is also equal to 0.1mm.

[0064] Furthermore, in this embodiment, the diverter 232 is arranged perpendicular to each second liquid absorption trough 231, and it divides the second liquid absorption trough 231 into two sections. The width of the diverter 232 is greater than the width of the second liquid absorption trough 231, thereby facilitating the improvement of the liquid absorption rate and preventing the liquid medium from penetrating from the electrode pores to the outside.

[0065] Further, in the present embodiment, the guide groove 233 is arranged on the side wall of the groove 211 and extends longitudinally along the base 20, and each second liquid suction groove 231 and each diverter groove 232 are correspondingly connected, which is used to guide the liquid medium into the second liquid suction groove 231 and the diverter groove 232. In the present embodiment, the opening of the guide groove 233 at one end away from the second liquid suction groove 231 and the diverter groove 232 is arranged on the outside of the atomizing chamber 311, which is used to absorb the leakage outside the atomizing chamber 311. In the present embodiment, a step 2111 is provided on the inner side wall of the groove 211, which is used to cooperate with the atomizing shell 31 of the atomizing assembly 30 to improve the tightness of the assembly. In the present embodiment, the guide groove 233 has a capillary force, which is used to absorb the leakage and cause the leakage to be caused to the second liquid suction groove 231. In this embodiment, the width of the guide groove 233 may be 0.05-1 mm. It is understandable that in other embodiments, the width of the guide groove 233 is not limited to 0.05-1 mm.

[0066] Furthermore, in this embodiment, the atomizer assembly 30 includes an atomizer shell 31 and an atomizer element 32; the atomizer shell 31 is sleeved on the base 20 and inserted into the groove 211. The atomizer shell 31 is used for mounting the atomizer element 32 to fix the atomizer element 32; the inner side of the atomizer shell 31 forms an atomizer chamber 311; the atomizer chamber 311 is located at the upper portion of the base 20 and is directly connected to the first liquid suction groove 122. The contact area between the atomizer shell 31 and the atomizer element 32 is prone to leakage, and the liquid medium is prone to leaking from the connection between the first seal 40 and the atomizer shell 31. By disposing the opening of the guide groove 233 away from the second liquid suction groove 231 and one end of the diverter groove 232 relative to the connection between the atomizer shell 31 and the first seal 40, specifically, facing the connection, the guide groove 233 absorbs the leaked liquid there by capillary force. The atomizing element 32 is disposed transversely within the atomizing shell 31 and includes an atomizing core 321 disposed within the atomizing shell 31 and a heating element 322 wound around the atomizing core 321. The atomizing core 321 may be a cotton wick, with both ends of the atomizing core 321 positioned on two sets of support columns on the base 21 and connected to the liquid-conducting element 60. The conductive connection portion of the heating element 322 penetrates the base 20 and connects to the electrode 90. In this embodiment, the heating element 322 may be a heating wire.

[0067] Furthermore, in this embodiment, the first sealing member 40 is sleeved on the base 20 and sleeved around the outer periphery of the atomizing housing 31. Specifically, the first sealing member 40 may be a sealing sleeve. The sealing sleeve may be a silicone sleeve or a rubber sleeve. It is understood that in other embodiments, the sealing sleeve is not limited to a silicone sleeve or a rubber sleeve.

[0068] Furthermore, in this embodiment, the gas-liquid balancing element 50 is cylindrical, specifically, it is a cylindrical shape with an elliptical or rectangular cross-section, and its outer periphery is combined with the inner wall surface of the shell 10 by an interference fit to seal the liquid storage cavity 111. In this embodiment, the gas-liquid balancing element 50 includes two first through holes 51, a liquid storage and ventilation structure 52 located outside the first through holes 51, and an air flow channel 53 located between the two first through holes 51. The first through holes 51 are provided for the liquid guide element 60 to pass through. The liquid storage and ventilation structure 52 is used to connect the liquid storage cavity 111 with the outside world to balance the air pressure in the liquid storage cavity 111. It includes a plurality of liquid storage grooves 521 arranged side by side to generate capillary force on the liquid medium and two return air grooves, which are used to store liquid to prevent leakage. The return air groove is arranged longitudinally, transversely intersecting the liquid storage tank 521, and connecting the liquid storage tank 521 with the liquid storage chamber 111. The return air groove facilitates the supply of gas into the liquid storage chamber 111. The air flow channel 53 is connected to the air outlet channel 121, so as to facilitate the connection between the air outlet channel 121 and the atomization chamber 311. By providing the gas-liquid balance element 50, a temperature ventilation process is formed to prevent the occurrence of oil frying and burnt odor caused by long-term lack of ventilation (insufficient liquid supply), and to prevent large particle droplets and leakage caused by sudden large-scale ventilation (excessive liquid supply). By forming an independent ventilation channel, the structural gap is sealed to prevent leakage caused by capillary force in the gap and environmental changes, and to prevent suction leakage and condensed liquid from being sucked out, thereby improving product yield.

[0069] Furthermore, in this embodiment, the liquid-conducting element 60 is disposed corresponding to the first through hole 51 on the gas-liquid balance element 50. The liquid-conducting element 60 is disposed in the first through hole 51 and is located at both ends of the atomizer core 321, thereby conducting liquid to the atomizer core 321. The liquid-conducting element 60 may be a cotton wick. It is understood that in other embodiments, the liquid-conducting element 60 is not limited to a cotton wick.

[0070] Furthermore, in this embodiment, the atomizer also includes a fixing sleeve 70; the fixing sleeve 70 facilitates fixing the conductive connection portion of the heating element 322, thereby facilitating the positioning of the conductive connection portion of the heating element 322. The conductive connection portion of the heating element 322 is inserted into the fixing sleeve 70. A second through hole 71 communicating with the atomizing chamber 311 is provided on the fixing sleeve 70. The second through hole 71 is arranged longitudinally and is connected to the air outlet channel 121 to facilitate gas circulation. In this embodiment, the fixing sleeve 70 can be a silicone sleeve. It is understandable that in some other embodiments, the fixing sleeve 70 can be omitted.

[0071] Furthermore, in this embodiment, the atomizer further includes a second sealing member 80. The second sealing member 80 may be a sealing sleeve that is sleeved over the gas-liquid balance element 50 and has clearance holes formed thereon corresponding to the liquid guide element 60 and the gas outlet channel 121. The second sealing member 80 may be a silicone sleeve or a rubber sleeve.

[0072] Furthermore, in this embodiment, the atomizer also includes an electrode 90, which includes two electrode columns, namely a positive electrode column and a negative electrode column, which are arranged side by side on the base 21, one end of which is connected to the conductive connection part of the heating element 322 through a lead, and the other end is conductively connected to the power supply device.

[0073] Figure 9-12 The second embodiment of the atomizer of the present invention is shown. The present invention constructs an atomizer comprising: a base 20; a housing 10 mounted on the base 20 and sealedly connected to the base 20 to form a liquid storage chamber 111; an electrode 90 disposed on the bottom of the base 20; an injection assembly 109 mounted on the base 20 to inject liquid into the liquid storage chamber 111; an atomizer body disposed on the base 20; an airflow channel extending throughout the atomizer; and a liquid absorption structure 101. The atomizer body includes an atomization assembly 30; the airflow channel includes an air inlet channel 131, an atomization chamber 311, and an air outlet channel 121. The liquid absorption structure 101 is disposed within the air outlet channel 121 and is circumferentially provided with multiple liquid storage grooves 105. These grooves 105 absorb condensed liquid in the air outlet channel 121 and / or incompletely atomized liquid carried over during inhalation through capillary action. In this embodiment, the liquid absorption structure 101 is made of one or more of PETG, PCTG, and PC.

[0074] Specifically, the liquid absorption structure 101 includes a plurality of fins 104, which are arranged in parallel and spaced apart in the longitudinal direction. A liquid storage tank 105 is formed between each two adjacent fins 104. The width of the liquid storage tank 105 is small enough to generate a capillary force on the condensed liquid, so that the smoke generated during the suction process will be retained in the liquid storage tank 105 due to the droplets brought out by the fin 104 structure, forming a liquid film in the liquid storage tank 105, and then stored in the liquid storage tank 105 to prevent leakage during suction.

[0075] The atomizer assembly 30 includes a cylindrical atomizer core 321, a liquid-conducting cotton 323 surrounding the atomizer core 321, and a heating element 322 wound around the atomizer core 321. The conductive connection portion of the heating element 322 penetrates the base 20 and connects to the electrode 90. In some embodiments, the heating element 322 may be a heating wire. During use, the atomizer core 321 absorbs the smoke liquid in the liquid storage chamber 111. The heating element 322 is energized and heated, causing the smoke liquid in the atomizer core 321 to be atomized. The user inhales through the suction port on the top cover of the atomizer. Under the action of suction, air enters the atomizer core 321 from the air inlet channel 131, mixes with the atomized smoke liquid in the atomizer core 321, and is discharged from the suction port on the top cover of the atomizer after passing through the air outlet channel 121.

[0076] In this embodiment, the liquid absorbing structure 101 includes a plurality of fins 104, which are arranged longitudinally in parallel or non-parallel intervals. A liquid reservoir 105 is formed between each adjacent fin 104. The width of the liquid reservoir 105 is small enough to generate a capillary force on the condensed liquid. As a result, the smoke generated during the inhalation process will be retained in the liquid reservoir 105 due to the passage of the fin 104 structure, forming a liquid film in the liquid reservoir 105, which is then stored in the liquid reservoir 105 to prevent leakage during the inhalation. The thickness of the fin 104 and the width of the liquid reservoir 105 are 0.1-0.5 mm, and preferably 0.15-0.3 mm.

[0077] To prevent excessive smoke liquid from being drawn out during inhalation when the liquid storage tank 105 in the liquid absorption structure 101 accumulates too much smoke liquid, in this embodiment, the liquid absorption structure 101 includes: at least one reflux groove 106 extending longitudinally, at least one reflux groove 106 longitudinally cutting at least a portion of the liquid storage tank 105. The reflux groove 106 is used to prevent the smoke liquid from flowing back to the atomizer core 321 along the reflux groove 106 to be atomized again when the liquid storage tank 105 accumulates too much smoke liquid. Specifically, two reflux grooves 106 with the same diameter are provided on the inner wall of the liquid absorption structure 101. The reflux grooves 106 longitudinally cut from the fin 104 below the top fin 104 of the liquid absorption structure 101 to the bottom fin 104. The top fin 104 of the liquid absorption structure 101 is used to prevent condensed liquid in the reflux groove 106 from flowing toward the air outlet channel 121.

[0078] Further, if Figure 12 As shown, in order to allow the refluxed smoke to be better absorbed by the atomizer core 321 and re-atomized, the length of the fin 104 at the bottom of the liquid absorbing structure 101 extending to the central axis of the liquid absorbing structure 101 is shorter than the length of the adjacent fin 104 extending to the central axis.

[0079] In some embodiments, the air outlet channel 121 and the atomizing assembly 30 are arranged adjacent to each other, and the liquid suction structure 101 and the air outlet channel 121 are an integrated structure, and the liquid storage tank 105 is provided on the inner wall surface of the air outlet channel 121. In this embodiment, Figure 12 As shown, the liquid absorption structure 101 and the air outlet channel 121 are separate structures. The liquid absorption structure 101 includes a cylindrical body, which is arranged directly above the atomization component 30. The shell 10 includes a body and an air outlet pipe 12 longitudinally arranged in the inner cavity of the body. The air inlet channel 131, the atomization cavity 311, the inner cavity of the liquid absorption structure 101, and the air outlet pipe 12 form a complete airflow channel.

[0080] The liquid absorption structure 101 is arranged directly above and close to the atomizer core 321 because: when the electronic cigarette is heated, due to the presence of an oil film in the atomization, bubbles generated during the atomization process can easily carry out incompletely atomized smoke liquid. When the smoke rises, the liquid absorption structure directly above the atomizer core 321 absorbs the droplets carried in the smoke and stores them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0081] A plurality of fins 104 are provided on the inner wall surface of the cylindrical body. Figure 12 As shown, the cylindrical body includes a first portion 102 and a second portion (not shown) that are detachably enclosed together. The inner wall surface of the first portion 102 is provided with a plurality of first fins, and the inner wall surface of the second portion is provided with a plurality of second fins. Specifically, the liquid-absorbing structure is cylindrical and can be composed of two semi-cylinders, and the fins are fan-shaped.

[0082] The atomizer assembly 30 and the liquid absorption structure 101 can also be arranged in the same sleeve 107, and the liquid absorption structure 101 is arranged adjacent to the atomizer assembly 30. At least one liquid inlet 110 is provided at the sleeve 107 corresponding to the atomizer assembly 30, for allowing the smoke liquid in the liquid storage chamber 111 to enter the atomizer core 321.

[0083] Furthermore, in order to fix the atomizing assembly 30 and the liquid absorbing structure 101 and facilitate installation, the outer wall of the liquid absorbing structure 101 is closely attached to the inner wall of the sleeve 107. In some embodiments, the liquid absorbing structure 101 and the sleeve 107 can be an integral structure.

[0084] In order to seal the connection between the sleeve 107 and the air outlet channel 121, a sealing member 108 is provided at the top of the liquid-absorbing structure 101 corresponding to the sleeve 107, which is sealed with the air outlet channel 121. The sealing member can be a silicone sleeve or a rubber sleeve. It is understood that in other embodiments, it is not limited to a silicone sleeve or a rubber sleeve.

[0085] The present invention also constructs an electronic atomization device, such as Figure 9-12As shown, it comprises: a base 20, a housing 10 mounted on the base 20 and sealed to the base 20 to form a liquid storage chamber 111, an electrode 90 disposed on the bottom of the base 20, a liquid injection assembly 109 mounted on the base 20 to inject liquid into the liquid storage chamber 111, an atomizer body disposed on the base 20, an airflow channel extending throughout the atomizer, and a liquid absorption structure 101. The atomizer body includes an atomization assembly 30, and the airflow channel includes an air inlet channel 131, an atomization chamber 311, and an air outlet channel 121. The liquid absorption structure 101 is disposed within the air outlet channel 121 and is circumferentially provided with multiple liquid storage grooves 105. The liquid storage grooves 105 absorb condensed liquid in the air outlet channel 121 and / or incompletely atomized liquid carried over during inhalation through capillary action. In this embodiment, the liquid absorption structure 101 is made of one or more of PETG, PCTG, and PC. The electronic atomization device is a disposable atomization device with a base, a shell and an atomizer body as an integrated structure, and can also be an atomization device with a base, a shell and an atomizer body as a separate structure.

[0086] Specifically, the liquid absorption structure 101 includes a plurality of fins 104, which are arranged in parallel and spaced apart in the longitudinal direction. A liquid storage tank 105 is formed between each two adjacent fins 104. The width of the liquid storage tank 105 is small enough to generate a capillary force on the condensed liquid, so that the smoke generated during the suction process will be retained in the liquid storage tank 105 due to the droplets brought out by the fin 104 structure, forming a liquid film in the liquid storage tank 105, and then stored in the liquid storage tank 105 to prevent leakage during suction.

[0087] The atomizer assembly 30 includes a cylindrical atomizer core 321, a liquid-conducting cotton 323 surrounding the atomizer core 321, and a heating element 322 wound around the atomizer core 321. The conductive connection portion of the heating element 322 penetrates the base 20 and connects to the electrode 90. In some embodiments, the heating element 322 may be a heating wire. During use, the atomizer core 321 absorbs the smoke liquid in the liquid storage chamber 111. The heating element 322 is energized and heated, causing the smoke liquid in the atomizer core 321 to be atomized. The user inhales through the suction port on the top cover of the atomizer. Under the action of suction, air enters the atomizer core 321 from the air inlet channel 131, mixes with the atomized smoke liquid in the atomizer core 321, and is discharged from the suction port on the top cover of the atomizer after passing through the air outlet channel 121.

[0088] In this embodiment, the liquid absorbing structure 101 includes a plurality of fins 104, which are arranged longitudinally in parallel or non-parallel intervals. A liquid reservoir 105 is formed between each adjacent fin 104. The width of the liquid reservoir 105 is small enough to generate a capillary force on the condensed liquid. As a result, the smoke generated during the inhalation process will be retained in the liquid reservoir 105 due to the passage of the fin 104 structure, forming a liquid film in the liquid reservoir 105, which is then stored in the liquid reservoir 105 to prevent leakage during the inhalation. The thickness of the fin 104 and the width of the liquid reservoir 105 are 0.1-0.5 mm, and preferably 0.15-0.3 mm.

[0089] To prevent excessive smoke liquid from being drawn out during inhalation when the liquid storage tank 105 in the liquid absorption structure 101 accumulates too much smoke liquid, in this embodiment, the liquid absorption structure 101 includes: at least one reflux groove 106 extending longitudinally, at least one reflux groove 106 longitudinally cutting at least a portion of the liquid storage tank 105. The reflux groove 106 is used to prevent the smoke liquid from flowing back to the atomizer core 321 along the reflux groove 106 to be atomized again when the liquid storage tank 105 accumulates too much smoke liquid. Specifically, two reflux grooves 106 with the same diameter are provided on the inner wall of the liquid absorption structure 101. The reflux grooves 106 longitudinally cut from the fin 104 below the top fin 104 of the liquid absorption structure 101 to the bottom fin 104. The top fin 104 of the liquid absorption structure 101 is used to prevent condensed liquid in the reflux groove 106 from flowing toward the air outlet channel 121.

[0090] Further, if Figure 12 As shown, in order to allow the refluxed smoke to be better absorbed by the atomizer core 321 and re-atomized, the length of the fin 104 at the bottom of the liquid absorbing structure 101 extending to the central axis of the liquid absorbing structure 101 is shorter than the length of the adjacent fin 104 extending to the central axis.

[0091] In some embodiments, the air outlet channel 121 and the atomizing assembly 30 are arranged adjacent to each other, and the liquid suction structure 101 and the air outlet channel 121 are an integrated structure, and the liquid storage tank 105 is provided on the inner wall surface of the air outlet channel 121. In this embodiment, Figure 12 As shown, the liquid absorption structure 101 and the air outlet channel 121 are separate structures. The liquid absorption structure 101 includes a cylindrical body, which is arranged directly above the atomization component 30. The shell 10 includes a body and an air outlet pipe 12 longitudinally arranged in the inner cavity of the body. The air inlet channel 131, the atomization cavity 311, the inner cavity of the liquid absorption structure 101, and the air outlet pipe 12 form a complete airflow channel.

[0092] The liquid absorption structure 101 is arranged directly above and close to the atomizer core 321 because: when the electronic cigarette is heated, due to the presence of an oil film in the atomization, bubbles generated during the atomization process can easily carry out incompletely atomized smoke liquid. When the smoke rises, the liquid absorption structure directly above the atomizer core 321 absorbs the droplets carried in the smoke and stores them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0093] A plurality of fins 104 are provided on the inner wall surface of the cylindrical body. Figure 12 As shown, the cylindrical body includes a first portion 102 and a second portion (not shown) that are detachably enclosed together. The inner wall surface of the first portion 102 is provided with a plurality of first fins, and the inner wall surface of the second portion is provided with a plurality of second fins. Specifically, the liquid-absorbing structure is cylindrical and can be composed of two semi-cylinders, and the fins are fan-shaped.

[0094] The atomizer assembly 30 and the liquid absorption structure 101 can also be arranged in the same sleeve 107, and the liquid absorption structure 101 is arranged adjacent to the atomizer assembly 30. At least one liquid inlet 110 is provided at the sleeve 107 corresponding to the atomizer assembly 30, for allowing the smoke liquid in the liquid storage chamber 111 to enter the atomizer core 321.

[0095] Furthermore, in order to fix the atomizing assembly 30 and the liquid absorbing structure 101 and facilitate installation, the outer wall of the liquid absorbing structure 101 is closely attached to the inner wall of the sleeve 107. In some embodiments, the liquid absorbing structure 101 and the sleeve 107 can be an integral structure.

[0096] In order to seal the connection between the sleeve 107 and the air outlet channel 121, a sealing member 108 is provided at the top of the liquid suction structure 101 corresponding to the sleeve 107, which is sealed to the air outlet channel 121. The sealing member can be a silicone sleeve or a rubber sleeve. It is understood that in other embodiments, it is not limited to a silicone sleeve or a rubber sleeve. By implementing the second embodiment, the following beneficial effects are achieved:

[0097] The present invention provides a liquid absorption structure in the air outlet channel, and the liquid absorption structure is circumferentially provided with multiple liquid storage tanks. The liquid storage tanks absorb condensed liquid in the air outlet channel through capillary force, so that the condensed liquid and / or the smoke liquid that is not completely atomized generated during the suction process are retained in the liquid storage tank, forming a liquid film in the liquid storage tank, and then stored in the liquid storage tank, thereby preventing the user from sucking and leaking during the suction process, and improving the user experience.

[0098] Moreover, the liquid absorption structure includes a plurality of fins, which are arranged in parallel and spaced apart in the longitudinal direction, and a liquid storage tank is formed between each two adjacent fins. The smoke generated during the suction process will be retained in the liquid storage tank due to the liquid droplets brought out by the fin structure.

[0099] In order to further prevent excessive liquid from being drawn out during inhalation when the liquid storage tank in the liquid absorption structure accumulates too much, the liquid absorption structure of the present invention includes at least one reflux groove extending longitudinally, and the at least one reflux groove longitudinally cuts through at least a portion of the liquid storage tank. The reflux groove is used to allow the liquid to flow back to the atomizer core along the reflux groove to be atomized again when excessive liquid is accumulated in the liquid storage tank.

[0100] In order to allow the refluxed smoke liquid to be better absorbed by the atomizer core and re-atomized, the length of the fin at the bottom of the liquid absorption structure extending to the central axis of the liquid absorption structure is shorter than the length of the adjacent fin extending to the central axis.

[0101] In addition, when the electronic cigarette is heated, due to the presence of an oil film in the atomization, the bubbles generated during the atomization process can easily carry out the incompletely atomized smoke liquid. When the smoke rises, the liquid absorption structure directly above the atomization core 321 absorbs the droplets carried in the smoke and stores them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0102] Figure 9 、 10 , 11, 13-17 show a third embodiment of the atomizer of the present invention, as shown in FIG. Figure 9 、 10 As shown in Figure 11, the present invention constructs an atomizer, including a base 20, a shell 10 that is mounted on the base 20 and is sealed with the base 20 to form a liquid storage chamber 111, an electrode 90 provided on the bottom of the base 20, a liquid injection component 109 installed on the base 20 to inject liquid into the liquid storage chamber 111, an atomizer body provided on the base 20, an air flow channel that runs through the entire atomizer, and a first liquid absorption structure and a second liquid absorption structure. Among them, the atomizer body includes an atomizing component 30, the air flow channel includes an air inlet channel 131, an atomizing chamber 311 and an air outlet channel 121, and the first liquid absorption structure and the second liquid absorption structure are connected on the air outlet channel 121 for guiding liquid. The first liquid absorption structure and the second liquid absorption structure absorb the condensation formed on the air outlet channel 121 by capillary force. The second liquid absorption structure is located between the atomizing component 30 and the first liquid absorption structure, and the capillary force of the second liquid absorption structure is greater than that of the first liquid absorption structure. The second liquid absorbent structure is provided with a liquid storage tank 105 for absorbing and storing condensed liquid by capillary force. The condensed liquid in the first liquid absorbent structure reaches the second liquid absorbent structure under the capillary force of the liquid storage tank 105 and is absorbed and stored.

[0103] In this embodiment, the second liquid absorbing structure has an inner wall with a depression forming a liquid storage tank 105. The inner wall of the second liquid absorbing structure encloses a portion of the air outlet channel 121. The first liquid absorbing structure is a liquid absorbing tank 122 extending longitudinally along the inner wall of the air outlet channel 121, with one end of the liquid absorbing tank 122 docking with the liquid storage tank 105.

[0104] In this embodiment, the air outlet channel 121 includes a detachable first airway wall and a second airway wall, the first liquid absorbing structure is formed on the first airway wall, and the second airway wall is the inner wall of the second liquid absorbing structure. Figure 11 As shown, the shell 10 includes a main body and an air outlet pipe 12 longitudinally arranged in the inner cavity of the main body, and the second liquid suction structure is arranged below the air outlet pipe 12. The first airway wall is the air outlet pipe 12, and the second airway wall is the inner wall of the second liquid suction structure. A complete air outlet channel 121 is formed by the air outlet pipe 12 and the inner cavity of the second liquid suction structure.

[0105] In other embodiments, the second liquid suction structure can be formed on a single integral component, for example, the outlet pipe 12 and the atomizing assembly 30 are arranged adjacent to each other, and the second liquid suction structure and the outlet pipe 12 can be an integral structure, with the liquid storage tank 105 provided on the inner wall of the outlet pipe 12. In this embodiment, the second liquid suction structure and the outlet pipe 12 are separate structures. The second liquid suction structure includes a cylindrical body, which is arranged directly above the atomizing assembly 30. The air inlet channel 131, the atomizing chamber 311, the inner cavity of the second liquid suction structure, and the outlet pipe 12 form a complete airflow channel.

[0106] like Figure 13 and 14 As shown, the air outlet pipe 12 includes a first end 1211 close to the atomizing assembly 30 and a second end 1212 away from the atomizing assembly 30. The liquid suction groove 122 extends longitudinally from the first end 1211 of the air outlet pipe 12 toward the second end 1212 of the air outlet pipe 12. There are several liquid suction grooves 122, which are evenly distributed along the peripheral wall of the air outlet channel 121 and are parallel to the central axis of the air outlet channel 121. The first liquid suction structure can be detachably connected or fixedly connected to the inner side wall of the air outlet pipe 12. In this embodiment, the first liquid suction structure is fixedly connected to the inner side wall of the air outlet pipe 12, that is, it is an integral structure with the air outlet pipe 12. At least one longitudinally extending liquid suction groove 122 is provided on the inner side wall of the air outlet pipe 12. The liquid suction groove 122 is not limited to a longitudinal arrangement. It can be spirally arranged, or inclined, or the inner side wall surface can be set to a rough surface texture to increase the wettability of the surface of the condensate. In other embodiments, the liquid leakage guide member is detachably fixed to the inner wall of the air outlet pipe 12 by means of gluing, snapping, or the like.

[0107] like Figure 11As shown, the atomizer assembly 30 includes a cylindrical atomizer core 321, a liquid-guiding cotton 323 surrounding the atomizer core 321, and a heating element 322 wound around the atomizer core 321. The conductive connection portion of the heating element 322 penetrates the base 20 and is connected to the electrode 90. In some embodiments, the heating element 322 can be a heating wire. When in use, the liquid-guiding cotton 323 absorbs the tobacco oil in the liquid storage chamber 111, and the heating element 322 is energized and heated, so that the tobacco oil in the atomizer core 321 is atomized. The user inhales through the suction port of the atomizer top cover. Under the action of suction, the air enters the atomizer core 321 from the air inlet channel, mixes with the atomized tobacco oil in the atomization chamber 311 of the atomizer core 321, and is discharged from the suction port of the atomizer top cover after passing through the air outlet channel 121.

[0108] When the atomized gas reaches the air outlet through the air outlet channel 121, the airflow around the air outlet channel 121 condenses against the inner wall of the air outlet pipe 12 to form e-liquid condensate. At this time, the liquid absorption groove 122 absorbs the condensate into the groove through capillary action. Since the capillary force of the liquid storage tank 105 is greater than the capillary force of the liquid absorption groove 122, the condensate in the liquid absorption groove 122 reaches the second liquid absorption structure under the capillary force of the liquid storage tank 105 and is absorbed and stored.

[0109] In order to allow the condensed liquid absorbed into the liquid absorption groove 122 to better flow back to the second liquid absorption structure under the capillary force of the liquid storage tank 105 and be absorbed and stored by the second liquid absorption structure, the groove depth of the liquid absorption groove 122 is set to gradually increase toward the liquid storage tank 105, that is, gradually increase from the second end 1212 to the first end 1211, and preferably, the groove depth of the liquid absorption groove 122 is greater than or equal to 0.1 mm.

[0110] The width of the liquid suction groove 122 can also be set to gradually increase toward the liquid storage tank 105, that is, gradually increase from the second end 1212 to the first end 1211, and the width of the liquid suction groove 122 can be set to gradually increase from its bottom to its opening. Preferably, the width of the liquid suction groove 122 is 0.05-1mm.

[0111] Based on the above embodiment of the first liquid absorbing structure, the bottom of the second liquid absorbing structure abuts against the liquid-guiding cotton 323 of the atomizing assembly 30. A reflux structure is provided at the bottom of the second liquid absorbing structure to connect the liquid reservoir 105 and the liquid-guiding cotton 323, allowing the condensed liquid in the liquid reservoir 105 to flow back into the liquid-guiding cotton 323 for absorption and reuse. The reflux structure can be a reflux groove, a liquid outlet, or a stepped structure.

[0112] like Figure 15As shown, in some embodiments, the liquid storage tank 105 is a horizontal liquid storage tank. Specifically, a plurality of first fins 104 are provided on the inner wall of the second liquid absorption structure. The first fins 104 are arranged in parallel and spaced apart in the longitudinal direction. A horizontal liquid storage tank is formed between each two adjacent first fins 104. The width of the liquid storage tank 105 is small enough to generate a capillary force on the condensate, so that the smoke generated during the suction process will be retained in the liquid storage tank 105 due to the droplets brought out by the first fin 104 structure, forming a liquid film in the liquid storage tank 105, and then stored in the liquid storage tank 105 to prevent leakage during suction.

[0113] To prevent excessive e-liquid from being drawn out during inhalation in the liquid reservoir 105 of the second liquid absorption structure and to enable the reuse of condensed liquid, in this embodiment, the second liquid absorption structure includes: at least one longitudinally extending reflux groove 106, which longitudinally cuts through at least a portion of the liquid reservoir 105. The reflux groove 106 is used to prevent excessive e-liquid from flowing back along the reflux groove 106 to the liquid guide cotton 323 for reabsorption and atomization when the liquid reservoir 105 accumulates excessive e-liquid. Preferably, two reflux grooves 106 of the same diameter are provided on the inner wall of the second liquid absorption structure. The reflux grooves 106 longitudinally cut through the first fin 104 at the bottom of the second liquid absorption structure. The first fin 104 at the top of the second liquid absorption structure is used to prevent condensed liquid in the reflux groove 106 from flowing toward the air outlet channel 121.

[0114] In order to allow the refluxed e-liquid to be better absorbed by the liquid-guiding cotton 323 and re-atomized, the length of the first fin 104 at the bottom of the second liquid-absorbing structure extending to the central axis of the second liquid-absorbing structure is shorter than the length of the adjacent first fin 104 extending to the central axis.

[0115] Because the condensed liquid in the liquid absorption groove 122 will reach the second liquid absorption structure for absorption and storage under the capillary force of the liquid storage tank 105, a first liquid guide port 117 corresponding to the liquid absorption groove 122 is provided on the first fin 104 at the top of the second liquid absorption structure. This is used to guide the condensed liquid in the liquid absorption groove 122 to the liquid storage tank 105 for better absorption and storage by the second liquid absorption structure. Specifically, in this embodiment, the second liquid absorption structure is cylindrical, the first fin 104 at the top is annular, and the other fins are fan-shaped. The first liquid guide port 117 is a recessed notch provided on the inner edge of the circle.

[0116] A plurality of first fins 104 are provided on the inner wall surface of the cylindrical body. Figure 15 As shown, the cylindrical body includes a first portion 102 and a second portion (not shown) that are detachably enclosed together. The inner walls of the first portion 102 and the second portion are provided with a plurality of first fins. Specifically, the second liquid-absorbing structure is cylindrical, and can be composed of two semi-cylinders. The top first fin 104 is semi-circular, and the other fins are fan-shaped.

[0117] like Figure 16 and 17 As shown, in some embodiments, the liquid storage tank 105 is a longitudinal liquid storage tank. Specifically, the second liquid absorption structure is a hollow structure with a top wall 113 on the top. A plurality of liquid storage plates 114 are provided longitudinally from the top wall 113 to the bottom. The liquid storage plates 114 are arranged at intervals, and a liquid storage tank 105 is formed between each two adjacent liquid storage plates 114.

[0118] To achieve better flow diversion and liquid aspiration, in this embodiment, the second liquid aspiration structure further includes at least one liquid guide groove 115 communicating with a portion of the liquid reservoir 105 for diverting condensate. Liquid guide groove 115 transversely intersects at least a portion of the middle portion of the liquid reservoir plate 114. In some embodiments, liquid guide groove 115 does not necessarily need to be parallel or perpendicular to the liquid reservoir 105; as long as cross-flow diversion is achieved, it is sufficient.

[0119] In order to achieve diversion at the bottom of the second wicking structure, the second wicking structure further comprises: at least one first step 116 for diverting condensate by transversely cutting the bottom of at least part of the liquid storage plates 114. In this embodiment, the bottoms of all the liquid storage plates 114 are transversely cut.

[0120] To allow the diverted condensate to flow back to the atomizer core for re-atomization, a second step 125 is provided on at least one of the first steps 116. In this embodiment, a second step 125 is provided on two first steps 116, and the first steps 116, the second steps 125, and the liquid storage tank 105 form a stepped structure.

[0121] Similarly, because the condensed liquid in the liquid absorbing groove 122 is absorbed and stored in the second liquid absorbing structure under the capillary force of the liquid storage tank 105, a second liquid guide port 118 is formed on the top wall 113 of the second liquid absorbing structure, corresponding to the liquid absorbing groove 122. Specifically, in this embodiment, the second liquid absorbing structure is cylindrical, the top wall 113 is annular, and the second liquid guide port 118 is a recess formed on the inner edge.

[0122] The plurality of liquid storage plates 114 are provided on the inner wall surface of the cylindrical body, which includes a first part and a second part that are detachably enclosed together, and the inner wall surfaces of the first part and the second part are provided with a plurality of liquid storage plates 114. Specifically, the second liquid absorption structure is cylindrical and can be composed of two semi-cylinders.

[0123] In some embodiments, the liquid storage tank 105 is a threaded liquid storage tank, including: second fins 120 spirally arranged on the inner wall to form the liquid storage tank 105 with a threaded structure.

[0124] In order to allow the condensed liquid in the liquid storage tank 105 to flow back to the atomizer core and be re-atomized, the second liquid suction structure includes at least one liquid outlet, which longitudinally cuts the second fin 120 at the bottom portion.

[0125] The second fins 120 are provided on the inner wall of the cylindrical body, which includes a first portion and a second portion that are detachably enclosed together, and the inner walls of the first portion and the second portion are provided with a plurality of second fins 120. Specifically, the second liquid absorbing structure is cylindrical and can be composed of two semi-cylinders.

[0126] In the above embodiment, the second liquid absorption structure is arranged directly above the atomizer core 321 and is arranged close to the atomizer core 321 because: when the electronic cigarette is heated and atomized, the mist passes through the air outlet channel and easily forms condensation on the airway wall. The second liquid absorption structure arranged directly above the atomizer assembly of the present invention can absorb the droplets carried in the smoke and store them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0127] Alternatively, the depth of the liquid storage tank 105 is greater than or equal to 0.1 mm, and the width of the liquid storage tank 105 is 0.05-1 mm. The material of the second liquid absorbing structure can also be one or more of PETG, PCTG and PC.

[0128] Furthermore, in this embodiment, if Figure 11 As shown, the atomizer assembly 30 and the second liquid absorption structure are also arranged in the same sleeve 107, and the second liquid absorption structure is arranged adjacent to the atomizer assembly 30. At least one liquid inlet 110 is provided at the sleeve 107 corresponding to the atomizer assembly 30, which is used to allow the smoke oil in the liquid storage chamber 111 to be absorbed by the liquid guide cotton 323.

[0129] In order to fix the atomizing assembly 30 and the second liquid absorbing structure and facilitate installation, the outer wall of the second liquid absorbing structure is closely attached to the inner wall of the sleeve 107. In some embodiments, the second liquid absorbing structure and the sleeve 107 can be an integral structure.

[0130] In order to seal the connection between the sleeve 107 and the air outlet channel 121, a sealing member 108 is provided at the sleeve 107 corresponding to the top of the second liquid-absorbing structure, which is sealed with the air outlet channel 121. The sealing member can be a silicone sleeve or a rubber sleeve. It is understood that in other embodiments, it is not limited to the silicone sleeve or the rubber sleeve.

[0131] The present invention also constructs an electronic atomization device, such as Figure 9 、 10As shown in Figure 11, it includes a base 20, a shell 10 that is mounted on the base 20 and is sealed to the base 20 to form a liquid storage chamber 111, an electrode 90 provided on the bottom of the base 20, a liquid injection assembly 109 installed on the base 20 to inject liquid into the liquid storage chamber 111, an atomizer body provided on the base 20, an air flow channel that runs through the entire atomizer, and a first liquid absorption structure and a second liquid absorption structure. Among them, the atomizer body includes an atomization assembly 30, the air flow channel includes an air inlet channel 131, an atomization chamber 311 and an air outlet channel 121, and the first liquid absorption structure and the second liquid absorption structure are connected in a liquid-conducting manner on the air outlet channel 121. The first liquid absorption structure and the second liquid absorption structure absorb condensation formed on the air outlet channel 121 through capillary force. The second liquid absorption structure is located between the atomization assembly 30 and the first liquid absorption structure, and the capillary force of the second liquid absorption structure is greater than that of the first liquid absorption structure. The second liquid absorption structure is provided with a liquid storage tank 105 that absorbs and stores condensation through capillary force. The condensed liquid in the first liquid absorption structure reaches the second liquid absorption structure under the capillary force of the liquid storage tank 105 and is absorbed and stored. In this embodiment, the electronic atomization device is a disposable atomization device with a base, a housing, and an atomizer body as an integrated structure, and can also be an atomization device with a base, a housing, and an atomizer body as separate structures.

[0132] In this embodiment, the second liquid absorbing structure has an inner wall with a depression forming a liquid storage tank 105. The inner wall of the second liquid absorbing structure encloses a portion of the air outlet channel 121. The first liquid absorbing structure is a liquid absorbing tank 122 extending longitudinally along the inner wall of the air outlet channel 121, with one end of the liquid absorbing tank 122 docking with the liquid storage tank 105.

[0133] In this embodiment, the air outlet channel 121 includes a detachable first airway wall and a second airway wall, the first liquid absorbing structure is formed on the first airway wall, and the second airway wall is the inner wall of the second liquid absorbing structure. Figure 11 As shown, the shell 10 includes a main body and an air outlet pipe 12 longitudinally arranged in the inner cavity of the main body, and the second liquid suction structure is arranged below the air outlet pipe 12. The first airway wall is the air outlet pipe 12, and the second airway wall is the inner wall of the second liquid suction structure. A complete air outlet channel 121 is formed by the air outlet pipe 12 and the inner cavity of the second liquid suction structure.

[0134] In other embodiments, the second liquid suction structure is formed on a single, integrally formed component, for example, the outlet pipe 12 and the atomizer assembly 30 are disposed adjacent to each other vertically, and the second liquid suction structure and the outlet pipe 12 may be an integral structure, with the liquid storage tank 105 disposed on the inner wall of the outlet pipe 12. In this embodiment, the second liquid suction structure and the outlet pipe 12 are separate structures. The second liquid suction structure includes a cylindrical body disposed directly above the atomizer assembly 30. The air inlet channel 131, the atomizer chamber 311, the inner cavity of the second liquid suction structure, and the outlet pipe 12 form a complete airflow channel.

[0135] like Figure 13 and 14 As shown, the air outlet pipe 12 includes a first end 1211 close to the atomizing assembly 30 and a second end 1212 away from the atomizing assembly 30. The liquid suction groove 122 extends longitudinally from the first end 1211 of the air outlet pipe 12 toward the second end 1212 of the air outlet pipe 12. There are several liquid suction grooves 122, which are evenly distributed along the peripheral wall of the air outlet channel 121 and are parallel to the central axis of the air outlet channel 121. The first liquid suction structure can be detachably connected or fixedly connected to the inner side wall of the air outlet pipe 12. In this embodiment, the first liquid suction structure is fixedly connected to the inner side wall of the air outlet pipe 12, that is, it is an integral structure with the air outlet pipe 12. At least one longitudinally extending liquid suction groove 122 is provided on the inner side wall of the air outlet pipe 12. The liquid suction groove 122 is not limited to a longitudinal arrangement. It can be spirally arranged, or inclined, or the inner side wall surface can be set to a rough surface texture to increase the wettability of the surface of the condensate. In other embodiments, the liquid leakage guide member is detachably fixed to the inner wall of the air outlet pipe 12 by means of gluing, snapping, or the like.

[0136] like Figure 11 As shown, the atomizer assembly 30 includes a cylindrical atomizer core 321, a liquid-guiding cotton 323 surrounding the atomizer core 321, and a heating element 322 wound around the atomizer core 321. The conductive connection portion of the heating element 322 penetrates the base 20 and is connected to the electrode 90. In some embodiments, the heating element 322 can be a heating wire. When in use, the liquid-guiding cotton 323 absorbs the tobacco oil in the liquid storage chamber 111, and the heating element 322 is energized and heated, so that the tobacco oil in the atomizer core 321 is atomized. The user inhales through the suction port of the atomizer top cover. Under the action of suction, the air enters the atomizer core 321 from the air inlet channel, mixes with the atomized tobacco oil in the atomization chamber 311 of the atomizer core 321, and is discharged from the suction port of the atomizer top cover after passing through the air outlet channel 121.

[0137] When the atomized gas reaches the air outlet through the air outlet channel 121, the airflow around the air outlet channel 121 condenses against the inner wall of the air outlet pipe 12 to form e-liquid condensate. At this time, the liquid absorption groove 122 absorbs the condensate into the groove through capillary action. Since the capillary force of the liquid storage tank 105 is greater than the capillary force of the liquid absorption groove 122, the condensate in the liquid absorption groove 122 reaches the second liquid absorption structure under the capillary force of the liquid storage tank 105 and is absorbed and stored.

[0138] In order to allow the condensed liquid absorbed into the liquid absorption groove 122 to better flow back to the second liquid absorption structure under the capillary force of the liquid storage tank 105 and be absorbed and stored by the second liquid absorption structure, the groove depth of the liquid absorption groove 122 is set to gradually increase toward the liquid storage tank 105, that is, gradually increase from the second end 1212 to the first end 1211, and preferably, the groove depth of the liquid absorption groove 122 is greater than or equal to 0.1 mm.

[0139] The width of the liquid suction groove 122 can also be set to gradually increase toward the liquid storage tank 105, that is, gradually increase from the second end 1212 to the first end 1211, and the width of the liquid suction groove 122 can be set to gradually increase from its bottom to its opening. Preferably, the width of the liquid suction groove 122 is 0.05-1mm.

[0140] Based on the above embodiment of the first liquid absorbing structure, the bottom of the second liquid absorbing structure abuts against the liquid-guiding cotton 323 of the atomizing assembly 30. A reflux structure is provided at the bottom of the second liquid absorbing structure to connect the liquid reservoir 105 and the liquid-guiding cotton 323, allowing the condensed liquid in the liquid reservoir 105 to flow back into the liquid-guiding cotton 323 for absorption and reuse. The reflux structure can be a reflux groove, a liquid outlet, or a stepped structure.

[0141] like Figure 15 As shown, in some embodiments, the liquid storage tank 105 is a horizontal liquid storage tank. Specifically, a plurality of first fins 104 are provided on the inner wall of the second liquid absorption structure. The first fins 104 are arranged in parallel and spaced apart in the longitudinal direction. A horizontal liquid storage tank is formed between each two adjacent first fins 104. The width of the liquid storage tank 105 is small enough to generate a capillary force on the condensate, so that the smoke generated during the suction process will be retained in the liquid storage tank 105 due to the droplets brought out by the first fin 104 structure, forming a liquid film in the liquid storage tank 105, and then stored in the liquid storage tank 105 to prevent leakage during suction.

[0142] To prevent excessive e-liquid from being drawn out during inhalation in the liquid reservoir 105 of the second liquid absorption structure and to enable the reuse of condensed liquid, in this embodiment, the second liquid absorption structure includes: at least one longitudinally extending reflux groove 106, which longitudinally cuts through at least a portion of the liquid reservoir 105. The reflux groove 106 is used to prevent excessive e-liquid from flowing back along the reflux groove 106 to the liquid guide cotton 323 for reabsorption and atomization when the liquid reservoir 105 accumulates excessive e-liquid. Preferably, two reflux grooves 106 of the same diameter are provided on the inner wall of the second liquid absorption structure. The reflux grooves 106 longitudinally cut through the first fin 104 at the bottom of the second liquid absorption structure. The first fin 104 at the top of the second liquid absorption structure is used to prevent condensed liquid in the reflux groove 106 from flowing toward the air outlet channel 121.

[0143] In order to allow the refluxed e-liquid to be better absorbed by the liquid-guiding cotton 323 and re-atomized, the length of the first fin 104 at the bottom of the second liquid-absorbing structure extending to the central axis of the second liquid-absorbing structure is shorter than the length of the adjacent first fin 104 extending to the central axis.

[0144] Because the condensed liquid in the liquid absorption groove 122 will reach the second liquid absorption structure for absorption and storage under the capillary force of the liquid storage tank 105, a first liquid guide port 117 corresponding to the liquid absorption groove 122 is provided on the first fin 104 at the top of the second liquid absorption structure. This is used to guide the condensed liquid in the liquid absorption groove 122 to the liquid storage tank 105 for better absorption and storage by the second liquid absorption structure. Specifically, in this embodiment, the second liquid absorption structure is cylindrical, the first fin 104 at the top is annular, and the other fins are fan-shaped. The first liquid guide port 117 is a recessed notch provided on the inner edge of the circle.

[0145] A plurality of first fins 104 are provided on the inner wall surface of the cylindrical body. Figure 15 As shown, the cylindrical body includes a first portion 102 and a second portion (not shown) that are detachably enclosed together. The inner walls of the first portion 102 and the second portion are provided with a plurality of first fins. Specifically, the second liquid-absorbing structure is cylindrical, and can be composed of two semi-cylinders. The top first fin 104 is semi-circular, and the other fins are fan-shaped.

[0146] like Figure 16 and 17 As shown, in some embodiments, the liquid storage tank 105 is a longitudinal liquid storage tank. Specifically, the second liquid absorption structure is a hollow structure with a top wall 113 on the top. A plurality of liquid storage plates 114 are provided longitudinally from the top wall 113 to the bottom. The liquid storage plates 114 are arranged at intervals, and a liquid storage tank 105 is formed between each two adjacent liquid storage plates 114.

[0147] To achieve better flow diversion and liquid aspiration, in this embodiment, the second liquid aspiration structure further includes at least one liquid guide groove 115 communicating with a portion of the liquid reservoir 105 for diverting condensate. Liquid guide groove 115 transversely intersects at least a portion of the middle portion of the liquid reservoir plate 114. In some embodiments, liquid guide groove 115 does not necessarily need to be parallel or perpendicular to the liquid reservoir 105; as long as cross-flow diversion is achieved, it is sufficient.

[0148] In order to achieve diversion at the bottom of the second wicking structure, the second wicking structure further comprises: at least one first step 116 for diverting condensate by transversely cutting the bottom of at least part of the liquid storage plates 114. In this embodiment, the bottoms of all the liquid storage plates 114 are transversely cut.

[0149] To allow the diverted condensate to flow back to the atomizer core for re-atomization, a second step 125 is provided on at least one of the first steps 116. In this embodiment, a second step 125 is provided on two first steps 116, and the first steps 116, the second steps 125, and the liquid storage tank 105 form a stepped structure.

[0150] Similarly, because the condensed liquid in the liquid absorbing groove 122 is absorbed and stored in the second liquid absorbing structure under the capillary force of the liquid storage tank 105, a second liquid guide port 118 is formed on the top wall 113 of the second liquid absorbing structure, corresponding to the liquid absorbing groove 122. Specifically, in this embodiment, the second liquid absorbing structure is cylindrical, the top wall 113 is annular, and the second liquid guide port 118 is a recess formed on the inner edge.

[0151] The plurality of liquid storage plates 114 are provided on the inner wall surface of the cylindrical body, which includes a first part and a second part that are detachably enclosed together, and the inner wall surfaces of the first part and the second part are provided with a plurality of liquid storage plates 114. Specifically, the second liquid absorption structure is cylindrical and can be composed of two semi-cylinders.

[0152] In some embodiments, the liquid storage tank 105 is a threaded liquid storage tank, including: second fins 120 spirally arranged on the inner wall to form the liquid storage tank 105 with a threaded structure.

[0153] In order to allow the condensed liquid in the liquid storage tank 105 to flow back to the atomizer core and be re-atomized, the second liquid suction structure includes at least one liquid outlet, which longitudinally cuts the second fin 120 at the bottom portion.

[0154] The second fins 120 are provided on the inner wall of the cylindrical body, which includes a first portion and a second portion that are detachably enclosed together, and the inner walls of the first portion and the second portion are provided with a plurality of second fins 120. Specifically, the second liquid absorbing structure is cylindrical and can be composed of two semi-cylinders.

[0155] In the above embodiment, the second liquid absorption structure is arranged directly above the atomizer core 321 and is arranged close to the atomizer core 321 because: when the electronic cigarette is heated and atomized, the mist passes through the air outlet channel and easily forms condensation on the airway wall. The second liquid absorption structure arranged directly above the atomizer assembly of the present invention can absorb the droplets carried in the smoke and store them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0156] Alternatively, the depth of the liquid storage tank 105 is greater than or equal to 0.1 mm, and the width of the liquid storage tank 105 is 0.05-1 mm. The material of the second liquid absorbing structure can also be one or more of PETG, PCTG and PC.

[0157] Furthermore, in this embodiment, if Figure 11 As shown, the atomizer assembly 30 and the second liquid absorption structure are also arranged in the same sleeve 107, and the second liquid absorption structure is arranged adjacent to the atomizer assembly 30. At least one liquid inlet 110 is provided at the sleeve 107 corresponding to the atomizer assembly 30, which is used to allow the smoke oil in the liquid storage chamber 111 to be absorbed by the liquid guide cotton 323.

[0158] In order to fix the atomizing assembly 30 and the second liquid absorbing structure and facilitate installation, the outer wall of the second liquid absorbing structure is closely attached to the inner wall of the sleeve 107. In some embodiments, the second liquid absorbing structure and the sleeve 107 can be an integral structure.

[0159] In order to seal the connection between the sleeve 107 and the air outlet channel 121, a sealing member 108 is provided at the sleeve 107 corresponding to the top of the second liquid-absorbing structure, which is sealed with the air outlet channel 121. The sealing member can be a silicone sleeve or a rubber sleeve. It is understood that in other embodiments, it is not limited to the silicone sleeve or the rubber sleeve.

[0160] By implementing the third embodiment, the following beneficial effects are achieved:

[0161] The present invention provides a first liquid absorption structure and a second liquid absorption structure connected to a liquid guide on the air outlet channel. The first liquid absorption structure and the second liquid absorption structure absorb condensed liquid formed on the air outlet channel through capillary force. The second liquid absorption structure is located between the atomization component and the first liquid absorption structure, and the capillary force of the second liquid absorption structure is greater than that of the first liquid absorption structure. The second liquid absorption structure is provided with a liquid storage tank for absorbing and storing condensed liquid through capillary force. The condensed liquid in the first liquid absorption structure reaches the second liquid absorption structure under the capillary force of the liquid storage tank and is absorbed and stored, so that the smoke oil that is not completely atomized during the puffing process and the condensed liquid generated on the air outlet channel can be absorbed and stored, thereby preventing the user from leaking during the puffing process and improving the user experience.

[0162] In addition, the bottom of the second liquid absorption structure of the present invention is in contact with the liquid-conducting cotton 323. A reflux structure is provided at the bottom of the second liquid absorption structure to connect the liquid storage tank and the liquid-conducting cotton 323, so that the condensed liquid in the liquid storage tank is recovered into the liquid-conducting cotton 323 to be re-atomized, thereby improving the utilization rate of the smoke oil.

[0163] When the electronic cigarette is heated and atomized, the mist passes through the air outlet channel and easily forms condensation on the airway wall. The second liquid absorption structure arranged directly above the atomization component of the present invention can absorb the droplets carried in the smoke and store them in the liquid storage tank, greatly reducing the possibility of leakage during suction.

[0164] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
