[0052] See also Figure 1 The present application provides an electronic atomization device 300, which can be used for atomization of an aerosol-generating substrate. The electronic atomization device 300 includes an atomizer 100 and a power supply assembly 200, and the atomizer 100 and the power supply assembly 200 are electrically connected.

[0053] The atomizer 100 is used to store and atomize the aerosol-generating matrix to form an aerosol for the user to inhale.

[0054] The specific structure and function of the atomizer 100 may refer to the specific structure and function of the atomizer 100 involved in the following embodiments, and the same or similar technical effects can be achieved, which will not be repeated here.

[0057] See also Figures 4 to 9 , Figure 4 yes Figure 3 A schematic cross-sectional view of the atomizer is provided. Figure 5 yes Figure 4 A partial enlarged schematic diagram of area A of the atomizer is provided, Figure 6 yes Figure 4 A schematic diagram of the structure of a first sealing member of the atomizer at an angle is provided, Figure 7 yes Figure 6 A schematic structural diagram of the first sealing member provided from another angle, Figure 8 yes Figure 6 A schematic cross-sectional view of a first seal is provided, Fig. 9 yes Figure 4 A schematic structural diagram of a first liquid suction component of a nebulizer is provided.

[0058] See also Figure 3 and Figure 4, the atomizer 100 includes a shell 1, a liquid storage part 2, an atomizing core 3, a first sealing part 4 and a first liquid absorbing part 5. Among them, the shell 1 has a liquid storage space 11 and a gas flow path (not shown in the figure), and the liquid storage part 2 is arranged in the liquid storage space 11. Specifically, the liquid storage part 2 has pores (not shown in the figure) for storing aerosol generating substrates. The atomizing core 3 is arranged in the shell 1, and the atomizing core 3 is fluidly connected with the liquid storage part 2 and the gas flow path, so that the aerosol generating substrate stored in the liquid storage part 2 can flow to the atomizing core 3, so that the atomizing core 3 heats the atomized aerosol generating substrate under power-on conditions to generate aerosol. The first sealing part 4 is arranged on one side of the liquid storage part 2, and the first liquid absorbing part 5 has an air outlet 51, which is a part of the gas flow path. The first sealing part 4 is provided with at least one back-inhalation channel (not shown in the figure), and the back-inhalation channel fluid is connected to the liquid storage part 2 and the first liquid absorbing part 5.

[0059] It can be understood that by providing a first sealing member 4 on one side of the liquid storage member 2 and providing a back-suction channel on the first sealing member 4, the liquid storage member 2 and the first liquid absorbing member 5 are connected by the back-suction channel fluid, so that the first liquid absorbing member 5 can absorb part of the condensate gathered at the position of the air outlet 51, thereby reducing the risk of the condensate flowing out of the atomizer 100. At the same time, when the first liquid absorbing member 5 absorbs the condensate to a saturated state and can no longer absorb the condensate, or when the first liquid absorbing member 5 absorbs the condensate at a speed that cannot keep up with the speed at which the aerosol generated by the atomization core 3 is condensed to form the condensate, the condensate absorbed in the first liquid absorbing member 5 and the condensate gathered at the position of the air outlet 51 can be directly sucked back into the liquid storage member 2 through the back-suction channel, which can effectively solve the problem of leakage caused by the large atomization amount of the high-power atomization core 3 and the untimely back-suction of the condensate, thereby preventing the user from sucking in the condensate during the suction process.

[0060] Specifically, in some embodiments, the gas flow path includes an outlet channel 12 and an air flow channel 21, the first sealing member 4 is disposed on a side of the liquid storage member 2 close to the outlet channel 12, and has a first vent 41 connected to the air flow channel 21, the first vent 41 is a part of the gas flow path, and the first liquid absorbing member 5 is disposed on a surface of the first sealing member 4 away from the liquid storage member 2, and has an outlet hole 51, and the outlet hole 51 connects the outlet channel 12 and the first vent 41. That is, the outlet channel 12 is spaced from the air flow channel 21 and the first vent 41, and the outlet channel 12 is connected to the air flow channel 21 through the outlet hole 51 and the first vent 41 in sequence.

[0061] In a specific embodiment, the air outlet channel 12 is formed on the housing 1, and an air flow channel 21 is formed inside the liquid storage part 2. The atomizer core 3 is arranged in the air flow channel 21 formed by the liquid storage part 2, and the air outlet channel 12 is located downstream of the atomizer core 3. The air flow channel 21, the first air vent 41, the air outlet hole 51 and the air outlet channel 12 are connected in sequence to form a partial gas flow path. In other embodiments, the air flow channel 21 may not be arranged inside the liquid storage part 2, and an air flow channel 21 independent of the liquid storage part 2 may be provided, as long as the air flow channel 21 can be connected to the air outlet channel 12, and it can be designed as needed.

[0062] In some embodiments, see Figures 4 to 8 The back-suction channel includes a first back-suction groove 42, a connecting groove 44, and a second back-suction groove 43 that are connected in sequence. Specifically, the surface of the first sealing member 4 close to the first liquid absorbing member 5 has at least one first back-suction groove 42, the surface of the first sealing member 4 close to the liquid storage member 2 has at least one second back-suction groove 43, and the side wall of the first vent hole 41 has at least one connecting groove 44 that connects the first back-suction groove 42 with the second back-suction groove 43.

[0063] Specifically, at least one first back-absorption groove 42 is provided on the surface of the first sealing member 4 close to the first liquid absorbent member 5, at least one second back-absorption groove 43 is provided on the surface of the first sealing member 4 away from the first liquid absorbent member 5, that is, on the surface close to the liquid storage member 2, and at least one connecting groove 44 is provided on the side wall of the first vent hole 41, and the connecting groove 44 connects the first back-absorption groove 42 and the second back-absorption groove 43 to form a back-absorption channel. When the first liquid absorbent member 5 absorbs condensed liquid to a saturated state and cannot absorb condensed liquid anymore, or when the first liquid absorbent member 5 absorbs liquid at a speed that cannot keep up with the speed at which the aerosol generated by atomization of the atomization core 3 condenses to form condensed liquid, the back-absorption groove structure of the first liquid absorbent member 5 can be connected to the first liquid absorbent member 5. The condensate and the condensate gathered at the position of the first vent hole 41 or in the air outlet channel 12 can be directly sucked back into the liquid storage part 2 through the first back-absorption groove 42, the connecting groove 44 and the second back-absorption groove 43, which can effectively solve the leakage problem caused by the large atomization amount of the high-power atomization core 3 and the untimely back-absorption of the condensate, which causes the condensate to flow out of the atomizer 100 from the air outlet channel 12 when the atomizer 100 is inverted, and prevent the user from sucking the condensate at the port position of the air outlet channel 12 during the suction process, and can also effectively avoid the gurgling sound caused by excessive accumulation of condensate in the air outlet channel 12, the first vent hole 41 and the air flow channel 21 of the atomizer 100, thereby improving the user experience.

[0064] In other embodiments, the back-suction channel can also be set as a through hole penetrating the first sealing member 4, and the through hole is spaced apart from the first ventilation hole 41 of the first sealing member 4. By setting at least one through hole penetrating the first sealing member 4 on the first sealing member 4, the first liquid absorption member 5 and the liquid storage member 2 can be directly fluidically connected through the through hole, and the condensed liquid absorbed by the first liquid absorption member 5 can be sucked back into the liquid storage member 2, thereby avoiding the problem of leakage caused by the condensed liquid flowing out of the atomizer 100 from the air outlet channel 12 when the condensed liquid absorbed by the first liquid absorption member 5 reaches a saturated state.

[0065] In other embodiments, the back-suction channel may only include a first back-suction groove 42 and a connecting groove 44 that are interconnected, that is, the back-suction channel may not include the second back-suction groove 43, the first back-suction groove 42 is arranged on the surface of the first sealing member 4 close to the first liquid absorbent member 5, the connecting groove 44 is arranged on the side wall of the first vent hole 41, and the end of the connecting groove 44 away from the first back-suction groove 42 is fluidly connected to the liquid storage member 2, so that the first liquid absorbent member 5 is fluidly connected to the liquid storage member 2 through the back-suction channel, so as to suck the condensed liquid absorbed by the first liquid absorbent member 5 back into the liquid storage member 2.

[0066] In other embodiments, the back-suction channel may only include a connecting groove 44 and a second back-suction groove 43 that are interconnected, the second back-suction groove 43 is arranged on the surface of the first sealing member 4 close to the liquid storage member 2, the connecting groove 44 is arranged on the side wall of the first vent hole 41, and the end of the connecting groove 44 away from the second back-suction groove 43 is fluidically connected to the first liquid absorption member 5 to absorb the condensed liquid absorbed by the first liquid absorption member 5 back into the liquid storage member 2.

[0067] In other embodiments, the back-suction channel may only include a connecting groove 44, which is disposed on the side wall of the first vent hole 41, one end of the connecting groove 44 is fluidly connected to the liquid storage member 2, and the other end of the connecting groove 44 is fluidly connected to the first liquid absorbent member 5, so as to suck the condensed liquid absorbed by the first liquid absorbent member 5 back into the liquid storage member 2.

[0068] The back-suction channel may be arranged in any of the above-mentioned ways, or in other ways, as long as the first liquid-absorbing component 5 and the liquid-storing component 2 can be fluidically connected through the back-suction channel so as to be able to suck the condensed liquid absorbed by the first liquid-absorbing component 5 back into the liquid-storing component 2. The design may be based on actual needs, and the present application does not impose any limitation thereto.

[0069] Specifically, in one embodiment, the power of the atomizer core 3 of the atomizer 100 of the electronic atomization device 300 is 14 to 30W, and the atomization amount of the atomizer core 3 of the user's single-mouth inhalation is 10 to 24 mg / puff. It can be understood that when the power of the atomizer core 3 is set to the above range, the atomization amount of the user's single-mouth inhalation is within the above range, the power of the atomizer core 3 is relatively large, and the amount of aerosol generated by atomization per unit time is relatively large. The first liquid absorption part 5 of the atomizer 100 of the present application and the first reabsorption groove 42, the connecting groove 44, and the second reabsorption groove 43 of the first sealing part 4 have more obvious reabsorption effects and higher efficiency, and the structural superiority of the present application is stronger.

[0070] See also Figures 4 to 9 In some embodiments, the diameter of the air flow channel 21 of the atomizer 100 is larger than the diameter of the air outlet channel 12, and along the direction from the liquid storage component 2 to the first liquid absorption component 5, the aperture of the first vent hole 41 of the first sealing component 4 gradually decreases, and the aperture of the first vent hole 41 near the air flow channel 21 is larger than the aperture near the air outlet channel 12. Specifically, the aperture of the first air vent 41 near the end of the air outlet channel 12 is equal to the diameter of the air outlet channel 12, and the aperture of the first air vent 41 near the end of the air flow channel 21 is greater than or equal to the diameter of the air flow channel 21. Preferably, the aperture of the first air vent 41 near the end of the air flow channel 21 is greater than the diameter of the air flow channel 21, so as to ensure that the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 can be better connected, and the condensate gathered at the position of the air outlet channel 12 and the first air vent 41 can flow more smoothly through the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 to the liquid storage component 2, so as to avoid the condensate flowing directly from the first air vent 41 to the air flow channel 21 without passing through the second back-suction groove 43, which causes the condensate to not be back-suctioned by the liquid storage component 2.

[0071] Specifically, Figure 4 As shown, the atomizer 100 further includes a vent pipe 6, which is disposed in the liquid storage member 2, and the inner wall surface of the vent pipe 6 defines an air flow channel 21. Specifically, as shown in FIG. Figure 4 As shown, the vent pipe 6 is a round pipe. In other embodiments, the vent pipe 6 can be set to any other shape. The outer wall surface of the vent pipe 6 and the inner wall surface of the housing 1 define a liquid storage space 11, and the liquid storage member 2 is arranged in the liquid storage space 11.

[0072] The atomization core 3 includes a liquid guide (not shown) and a heating element (not shown), the liquid guide is in fluid communication with the liquid storage part 2, the heating element is arranged on the atomization surface (not shown) of the liquid guide, and the heating element is electrically connected to the power supply assembly 200 of the electronic atomization device 300 to heat the aerosol generating matrix in the atomization liquid guide under heating conditions to generate an aerosol. The liquid guide of the atomization core 3 is enclosed inside to form an atomization cavity (not shown), and the atomization cavity is connected to the airflow channel 21. The heating element can be any element such as a heating net, a heating film or a heating wire. The liquid guide can be a porous structure such as a liquid guide cotton or porous ceramics, porous glass, etc.

[0073] The atomizer core 3 can be arranged in the ventilation tube 6, and the atomizer core 3 is fluidly connected to the liquid storage component 2. Specifically, a liquid inlet hole (not marked in the figure) can be arranged on the tube wall of the ventilation tube 6, so that the liquid guide component of the atomizer core 3 is fluidly connected to the liquid storage component 2, and the atomization cavity of the atomizer core 3 is connected to the air flow channel 21; or, the atomizer core 3 can be directly arranged in the liquid storage component 2, so that the atomization cavity of the atomizer core 3 is connected to the air flow channel 21.

[0074] In some embodiments, the atomizer core 3 may include two heating elements that are spaced apart. For example, the atomizer core 3 includes two heating nets that are spaced apart in the extension direction of the airflow channel 21. The two heating nets are electrically connected to the power supply assembly 200, respectively, to form a high-power atomizer core 3, thereby improving the heating efficiency and atomization efficiency of the atomizer core 3.

[0075] In some embodiments, Figure 4 As shown, one end of the vent tube 6 protrudes from the surface of the liquid storage member 2 close to the first sealing member 4, and the portion of the vent tube 6 protruding from the liquid storage member 2 is inserted into the end of the first vent hole 41 close to the liquid storage member 2. Specifically, the end of the vent tube 6 close to the air outlet channel 12 is spaced apart from the end of the first vent hole 41 close to the air outlet channel 12, that is, the vent tube 6 is connected to the air outlet hole 51 by means of the first vent hole 41, and is not directly connected to the air outlet hole 51 or the air outlet channel 12. This arrangement can ensure that the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 of the first sealing member 4 can fully exert their back-suction effect, and avoid the problem that the vent tube 6 is directly connected to the air outlet channel 12, resulting in the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 being unable to achieve the back-suction effect, thereby causing the condensate to still flow out of the atomizer 100.

[0076] In some embodiments, a convex ring (not marked in the figure) can be provided on the surface of the first sealing member 4 close to the liquid storage member 2 at a position corresponding to the first ventilation hole 41 and the ventilation tube 6. The convex ring is provided around the first ventilation hole 41, and the portion of the ventilation tube 6 protruding from the liquid storage member 2 is inserted into the convex ring, and the outer side surface of the ventilation tube 6 is spaced apart from the inner side surface of the convex ring. The height of the portion of the ventilation tube 6 protruding from the liquid storage member 2 is equal to the height of the protrusion, so as to further ensure the back-suction effect of the connecting groove 44, the first back-suction groove 42 and the second back-suction groove 43.

[0077] Most of the aerosol generated by atomization of the atomizing core 3 flows into the air flow channel 21 through the atomizing chamber, and then flows to the air outlet channel 12 through the air flow channel 21, the first air hole 41, and the air outlet hole 51 in sequence, and is finally inhaled at the port position of the air outlet channel 12 away from the air outlet hole 51. A small part of the aerosol is inhaled in the air flow channel 21 and the air outlet hole 51. Figure 4 Specifically, a small amount of aerosol gathers at the first vent hole 41 and the outlet hole 51, and condenses to form condensate. It can be understood that since the diameter of the airflow channel 21 of the atomizer 100 is larger than the diameter of the outlet channel 12, and the aperture of the first vent hole 41 of the first sealing member 4 gradually decreases along the direction from the liquid storage member 2 to the first liquid absorbing member 5, Figure 4 The position of region B in the figure is the connection position where the large-aperture air flow channel 21 is converted to the small-aperture air outlet channel 12. Therefore, the aperture change at this position makes it easier for the condensate to gather at the first vent hole 41 and the air outlet hole 51 to form condensate. By providing the first liquid absorbing member 5 and the first reabsorption groove 42, the connecting groove 44 and the second reabsorption groove 43 that are interconnected, the condensate at this position can be effectively reabsorbed into the liquid storage member 2. Specifically, as Figure 5 As shown, the flow path S of the back-absorbed condensate is to pass through the first back-absorbed groove 42 and the connecting groove 44 in sequence, and part of it directly enters the liquid storage part 2, and part of it flows into the liquid storage part 2 in the process of flowing through the second back-absorbed groove 43, thereby realizing the absorption of the condensate by the liquid storage part 2.

[0078] See also Figures 6 to 8In some embodiments, the surface of the first seal 4 close to the first liquid absorbing member 5 has a plurality of first re-absorption grooves 42, and the plurality of first re-absorption grooves 42 are arranged at intervals along the circumference of the first seal 4, and each first re-absorption groove 42 extends radially along the first seal 4. Specifically, the plurality of first re-absorption grooves 42 radiate outward from the first vent 41, that is, along the position from the first vent 41 of the first seal 4 to the edge of the first seal 4, the distance between two adjacent first re-absorption grooves 42 gradually increases. It can be understood that since the condensate is easier to gather closer to the first vent 41, the distance between two adjacent first re-absorption grooves 42 is set so that the end close to the first vent 41 is greater than the end away from the first vent 41, which can ensure that the first re-absorption groove 42 has a stronger re-absorption ability and higher efficiency at the position close to the first vent 41. Among them, the first re-absorption groove 42 can extend in any manner such as a straight line, a curve, or a broken line. Preferably, one end of the first back-suction groove 42 away from the first vent hole 41 extends to the side of the first sealing member 4 to increase the length of the first back-suction groove 42 and improve the capacity of the first back-suction groove 42 .

[0079] In other embodiments, only one first back-suction groove 42 may be provided, the first back-suction groove 42 may extend in any other direction, and the first back-suction groove 42 may be provided in any shape such as annular or arcuate, as long as one end of the first back-suction groove 42 can be connected to the connecting groove 44. The end of the first back-suction groove 42 away from the first vent hole 41 may not extend to the side of the first sealing member 4, that is, the end of the first back-suction groove 42 away from the first vent hole 41 is spaced from the side of the first sealing member 4, and the design can be performed as needed.

[0080] See also Figures 6 to 8 In some embodiments, the side wall of the first vent hole 41 has a plurality of connecting grooves 44, and the plurality of connecting grooves 44 are arranged at intervals along the circumference of the first vent hole 41. Specifically, the connecting groove 44 extends from the surface of the first sealing member 4 close to the first liquid absorbent member 5 to the surface of the first sealing member 4 away from the first liquid absorbent member 5, so as to connect the first back-suction groove 42 with the second back-suction groove 43. In other embodiments, only one connecting groove 44 may be provided, as long as the first back-suction groove 42 and the second back-suction groove 43 can be connected.

[0081] See also Figures 6 to 8In some embodiments, the surface of the first seal 4 close to the liquid storage part 2 has a plurality of second back-suction grooves 43, and the plurality of second back-suction grooves 43 are arranged at intervals along the circumference of the first seal 4. Specifically, each second back-suction groove 43 also extends radially along the first seal 4. Specifically, the plurality of second back-suction grooves 43 radiate outward from the first vent 41, that is, along the position from the first vent 41 of the first seal 4 to the edge of the first seal 4, the distance between two adjacent second back-suction grooves 43 gradually increases. Similarly, setting the distance between two adjacent second back-suction grooves 43 so that the end close to the first vent 41 is greater than the end away from the first vent 41 can ensure that the second back-suction groove 43 has a stronger back-suction ability and higher efficiency at the position close to the first vent 41. Among them, the second back-suction groove 43 can extend in any manner such as a straight line, a curve, a broken line, etc. Preferably, one end of the second back-suction groove 43 away from the first vent hole 41 extends to the side of the first sealing member 4 to increase the length of the second back-suction groove 43 and improve the capacity of the second back-suction groove 43 .

[0082] In other embodiments, only one second back-suction groove 43 may be provided, the second back-suction groove 43 may extend in any other direction, and the second back-suction groove 43 may be provided in any shape such as annular or arcuate, as long as one end of the second back-suction groove 43 can be connected to the connecting groove 44. The end of the second back-suction groove 43 away from the first vent hole 41 may not extend to the side of the first sealing member 4, that is, the end of the second back-suction groove 43 away from the first vent hole 41 is spaced from the side of the first sealing member 4, and the design can be performed as needed.

The third back-suction groove 45 is connected with the plurality of first back-suction grooves 42, that is, the plurality of first back-suction grooves 42 are connected with each other through the annular third back-suction groove 45. When the first back-suction groove 42 is connected with the connecting groove 44, only one first back-suction groove 42 needs to be connected with the connecting groove 44 to realize fluid connection between all the first back-suction grooves 42 and the connecting groove 44.

[0084] In other embodiments, a plurality of third back-suction grooves 45 may be provided, for example, two, three or four, each of which may be annular, and a plurality of third back-suction grooves 45 may be spaced apart from each other in the radial direction of the first seal 4, and each third back-suction groove 45 may be connected to only part of the first back-suction grooves 42, or may be connected to all of the first back-suction grooves 42; or, the third back-suction groove 45 may be provided as one, and one third back-suction groove 45 may not be annular, for example, it may be in any shape such as arc, straight line, etc., and one third back-suction groove 45 may be connected to only part of the first back-suction grooves 42; or, the third back-suction groove 45 may be provided as a straight line or a curved structure, and each third back-suction groove 45 may be connected to part of the first back-suction grooves 42, or may be connected to all of the first back-suction grooves 42, and a plurality of third back-suction grooves 45 may be arbitrarily distributed along any direction.

[0089] Specifically, in some embodiments, the number of the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 is equal. For example, the first back-suction groove 42, the connecting groove 44 and the second back-suction groove 43 are all provided in multiple and equal numbers.

[0091] In some embodiments, the number of the first back-suction grooves 42 may be less than the number of the connecting grooves 44, or may be equal to the number of the connecting grooves 44.

Preferably, the density of the liquid storage cotton is 0.07±0.02g / cm3, and / or the density of the liquid absorbent cotton is 0.175±0.02g / cm3, so as to ensure that the liquid conduction rate of the liquid storage member 2 is greater than the liquid conduction rate of the first liquid absorbent member 5, and ensure that the condensed liquid in the first liquid absorbent member 5 or the condensed liquid in the first vent 41 and the air outlet 51 can be smoothly sucked back into the liquid storage cotton via the first re-absorption groove 42, the connecting groove 44 and the second re-absorption groove 43.

[0095] In some embodiments, the liquid injection amount of the liquid storage part 2 accounts for less than 75% of the total amount of the aerosol generating matrix that the liquid storage part 2 can accommodate, so as to ensure that the liquid storage part 2 has sufficient ability to absorb condensed liquid, and avoid the problem that the liquid storage part 2 cannot absorb the condensed liquid in time during the atomization process due to excessive liquid injection or the liquid storage part 2 being close to saturation, causing the condensed liquid to flow out of the atomizer 100.

Specifically, the base 9 has an air inlet 91 and an electrode hole 92. The electrode hole 92 and the air inlet 91 are correspondingly located in the space formed by the avoidance hole 81, and the avoidance hole 81 connects the air inlet 91 and the air flow channel 21, so that the external airflow can enter the air flow channel 21 through the air inlet 91, the avoidance hole 81 and the second air hole 71 in sequence, and then carry the aerosol generated by atomization to the position of the air outlet channel 12, and flow through the entire gas flow path.

In some embodiments, the width of the seventh re-absorption groove 73 is 0.1-2 mm, and the depth of the seventh re-absorption groove 73 is 0.1-2 mm.
