Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] The present application provides an electronic atomization device 100, referring to Figure 1 , Figure 1 is a structural schematic diagram of an embodiment of the electronic atomization device provided by the present application.

[0032] The electronic atomization device 100 includes an atomizer 10 and a flavor enhancer 20. The atomizer 10 has an aerosol passage 12, and is used to atomize an aerosol substrate and generate an aerosol into the aerosol passage 12. The flavor enhancer 20 is connected with the atomizer 10. The flavor enhancer 20 has a containing cavity 201, a second air hole 202 and a first air hole 203 in communication with the containing cavity 201. The containing cavity 201 is used to contain a flavor enhancing substrate. The second air hole 202 is also in communication with the aerosol passage 12. The first air hole 203 is in communication with the outside atmosphere, and the flavor enhancing airway for supplying air to the aerosol passage 12 is formed by the first air hole 203, the containing cavity 201 and the second air hole 202.

[0033] The atomizer 10 can include a housing 11 and an atomizing core 13 connected in the housing 11, the housing 11 and the atomizing core 13 can define a liquid storage cavity 101, the liquid storage cavity 101 can store an aerosol substrate, or the liquid storage cavity 101 is provided with a liquid storage piece 15 to store the aerosol substrate in a storage mode, thereby reducing the volatility of the aerosol substrate; the atomizing core 13 can atomize the aerosol substrate and generate an aerosol into the gas mist passage 12, the atomizing core 13 can be directly provided in the gas mist passage 12 and atomize the aerosol substrate to generate the aerosol, or the atomizing core 13 atomizes the aerosol substrate to generate the aerosol, and then the aerosol enters the gas mist passage 12, and the aerosol can be guided to the suction nozzle of the atomizer 10 along the gas mist passage 12; wherein the atomizing core 13 can be a ceramic atomizing core or a liquid-absorbing cotton atomizing core, etc.

[0034] The connection mode between the flavor enhancer 20 and the atomizer 10 includes abutment, clamping, screwing or gluing, etc., for example, the flavor enhancer 20 and the atomizer 10 are installed in the same shell and abut each other and make the second air hole 202 communicate with the gas mist passage 12; or the end portions of the flavor enhancer 20 and the atomizer 10 are clamped.

[0035] Further, the atomizer 10 and the flavor enhancer 20 are connected and form an isolation cavity 102, the isolation cavity 102 is located between the gas mist passage 12 and the second air hole 202, the isolation tube 103 surrounding the second air hole 202 is formed on the wall surface of the bottom wall of the isolation cavity 102, the height of the isolation tube 103 extending to the atomizer 10 is higher than the bottom wall of the isolation cavity 102, and the isolation tube 103 is spaced apart from the gas mist passage 12, so that the isolation cavity 102 can store a part of the condensate or other substances brought out from the flavor enhancer 20, so that the user can inhale more pure aerosol or flavored aerosol, and the user experience is improved.

[0036] The isolation cavity 102 is used to isolate the condensate generated in the gas mist passage 12, to prevent the condensate from flowing back into the flavor enhancer 20 and polluting the flavoring substrate in the containing cavity 201; wherein the isolation tube 103 is used to block the liquid in the isolation cavity 102 from entering the second air hole 202.

[0037] Further, the second air hole 202 can also be disposed in a staggered manner with the gas mist passage 12 to avoid the condensate formed in the gas mist passage 12 from dropping into the second air hole 202.

[0038] The flavor enhancer 20 is provided with a flavoring air channel for supplying gas to the gas mist passage 12 of the atomizer 10, wherein the gas flow flowing into the atomizer 10 must pass through the flavoring air channel, so that the gas flow contacts or impacts the flavoring substrate in the flavor enhancer 20 to stir the flavoring substrate, thereby carrying the smell of the flavoring substrate, or carrying the flavoring substrate smell emitted by the flavoring substrate, and the flavoring substrate smell is finally mixed with the aerosol, thereby improving the taste of the aerosol.

[0039] The flavoring substrate can be a liquid flavoring substrate, a solid flavoring substrate, or a gelatinous flavoring substrate, etc.

[0040] For example, the flavoring substrate is in a granular structure, and the gaps between the granular flavoring substrates form flavoring air channels, so there is at least one flavoring air channel in the flavoring device 20, and there can also be 3, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, etc. flavoring air channels, which are not limited here; when the airflow passes through the containing cavity 201, it will cause the granular flavoring substrates to collide and stir with each other, thereby generating the flavoring substrate odor.

[0041] Alternatively, for example, the flavoring substrate is in a paste or gelatinous state, and the airflow can pass through the flavoring air channels formed on the surface of the paste or gelatinous flavoring substrate, or the airflow can pass through the flavoring air channels formed inside the paste or gelatinous flavoring substrate, which is triggered by the airflow, and the volatilization speed of the flavoring substrate is accelerated, thereby generating a stronger flavoring substrate odor.

[0042] Alternatively, for example, the flavoring substrate is a solid-liquid mixture, such as a granular flavoring substrate placed in a solvent, when the airflow flows from the first air hole 203 and passes through the granular flavoring substrate placed in the solvent, a flavoring air channel is formed in the solvent, i.e. a gas bubble is generated in the solvent, which can also produce a stronger flavoring substrate odor under the agitation of the gas bubble.

[0043] The present application sets the flavoring device 20 in the air inlet path of the atomizer 10, so that the air flow in the air mist channel 12 leading to the atomizer 10 must pass through the flavoring air channel of the flavoring device 20, so that the flavoring substrate in the containing cavity 201 of the flavoring device 20 is constantly impacted under the agitation of the airflow, and the airflow carries the flavoring substrate odor, the airflow with the flavoring substrate odor enters the atomizer 10 and mixes with the generated aerosol, thereby improving the taste of the aerosol, and avoiding the problem of easy burning caused by the interaction between the atomizing core 13 in the atomizer 10 and the flavoring substrate.

[0044] For reference Figure 1 and Figure 2 , Figure 2 is as Figure 1 shown in the cross-sectional structure of an embodiment of the flavoring device in the electronic atomization device. Figure 1 The path line with an arrow in the figure is the flow path of the airflow in the flavoring device 20 and the atomizer 10.

[0045] The fragrance enhancer 20 comprises a cavity 21 and a first leakage prevention member 22. The cavity 21 has a containing cavity 201 and is provided with a second air hole 202 and a first air hole 203 at two ends respectively. The first leakage prevention member 22 is connected to the first air hole 203. The first leakage prevention member 22 forms a first through hole 204 and a second through hole 205 with a height difference. When the electronic atomization device 100 is placed on a horizontal plane, the distance between the first through hole 204 and the horizontal plane is higher than the distance between the second through hole 205 and the horizontal plane. The first air hole 203 is communicated with the containing cavity 201 through the first through hole 204 and the second through hole 205 in sequence. That is, the airflow passes through the first air hole 203, the first through hole 204, and the second through hole 205 in sequence to enter the containing cavity 201. Thus, the height difference between the first through hole 204 and the second through hole 205 can form a leakage prevention protection, avoiding the leakage of the fragrance base in the containing cavity 201 from the first air hole 203, especially for the liquid, granular or powder forms of the fragrance base. At the same time, the airflow enters the containing cavity 201 from the second through hole 205 and contacts the fragrance base to form a fragrance airway, so as to bring the fragrance in the fragrance base into the aerosol channel 12 to mix with the aerosol for the user to smoke.

[0046] The distance between the second through hole 205 and the bottom wall of the cavity 21 is 0-10 mm, for example, the second through hole 205 is flush with the bottom wall of the containing cavity 201, or the distance between the second through hole 205 and the bottom wall of the containing cavity 201 is 0.1-10 mm, preferably 0.3-5 mm. Thus, the airflow passing through the second through hole 205 into the containing cavity 201 can contact the fragrance base in the containing cavity 201 more fully, and the carried-out fragrance is more sufficient, improving the user experience.

[0047] The first leakage prevention member 22 is connected to the first air hole 203 at least, so that the airflow flowing in through the first air hole 203 must pass through the first leakage prevention member 22. The flow track of the airflow in the first leakage prevention member 22 is similar to an N-shaped track, so as to guide the airflow to the bottom of the containing cavity 201, that is, to make the airflow flow upward from the bottom of the containing cavity 201, pass through the entire containing cavity 201, and then flow from the second air hole 202 to the aerosol channel of the atomizer 10, so as to make the airflow contact the fragrance base more fully, and thus the smell of the fragrance base emitted is carried into the atomizer 10 to mix with the aerosol, enhancing the taste performance of the aerosol.

[0048] Further, the fragrance base itself can also block the second through hole 205, so as to block most of the fragrance base from leaking from the first air hole 203. For example, if the fragrance base is in a liquid state, it can seal the second through hole 205; if the fragrance base is in a solid or gel state, it is more difficult to leak from the first air hole 203.

[0049] In the embodiment, the first leakage prevention member 22 includes a first leakage prevention tube 221 and a second leakage prevention tube 222, the first leakage prevention tube 221 is sleeved in the second leakage prevention tube 222, the first leakage prevention tube 221 is connected to the first air hole 203, a leakage prevention cavity 206 is formed between the first leakage prevention tube 221 and the second leakage prevention tube 222, the first leakage prevention tube 221 is provided with a first through hole 204 communicating with the leakage prevention cavity 206, the second leakage prevention tube 222 is provided with a second through hole 205 communicating with the leakage prevention cavity 206 and the accommodating cavity 201, and the first through hole 204 is higher than the second through hole 205 in the direction from the bottom wall of the cavity 21 to the top wall of the cavity 21.

[0050] The bottom of the second leakage prevention tube 222 is provided with a plurality of second through holes 205, and the top side wall of the first leakage prevention tube 221 is provided with a plurality of first through holes 204, so that a height difference is formed between the first through hole 204 and the second through hole 205, the second through hole 205 is located at the bottom of the accommodating cavity 201, and when the airflow enters the accommodating cavity 201 from the second through hole 205, the airflow can be more fully contacted with the flavoring substrate in the accommodating cavity 201, and when the electronic atomization device 100 is used, even if the flavoring substrate enters the leakage prevention cavity 206 from the second through hole 205, the part of the flavoring substrate still needs to overcome the height difference to leak from the first through hole 204 to the first air hole 203 and outside, so that the first leakage prevention member 22 provided by the application can greatly increase the aerosol aroma while reducing the risk of leakage of the flavoring substrate and improving the user experience.

[0051] The bottom of the second leakage prevention tube 222 is provided with a plurality of second through holes 205 in the circumferential direction, and in the process of changing the electronic atomization device 100 from the upright position to the inverted position, the plurality of second through holes 205 can facilitate the flavoring substrate entering the leakage prevention cavity 206 to flow back to the accommodating cavity 201, so as to avoid the phenomenon that too much flavoring substrate accumulates in the accommodating cavity 201 and is missed.

[0052] Optionally, as shown in Figure 2 One end of the first leakage prevention tube 221 is connected to the first air hole 203, the other end of the first leakage prevention tube 221 away from the first air hole 203 is connected to the second leakage prevention tube 222, and the end of the second leakage prevention tube 222 away from the second air hole 202 abuts against the bottom wall of the cavity 21. The first through hole 204 is arranged on the side wall of the first leakage prevention tube 221 and is flush with the connection position of the second leakage prevention tube 222, so that the first through hole 204 communicates with the leakage prevention cavity 206, and when the electronic atomization device 100 is vertically placed on the horizontal plane, the first through hole 204 is located at the top end of the leakage prevention cavity 206.

[0053] The first leakage prevention pipe 221 can be inserted into the first air hole 203. The first leakage prevention pipe 221 and the second leakage prevention pipe 222 can also be inserted into each other. One end of the second leakage prevention pipe 222 can abut against the bottom wall of the cavity 21. The distance between the second air hole 205 and the bottom wall of the cavity 21 is 0-10 mm, preferably 0-5 mm, so that the airflow enters the containing cavity 201 from the second air hole 205 or flows into the containing cavity 201 close to the bottom wall of the containing cavity 201, thereby increasing the contact area between the airflow and the flavoring substrate in the containing cavity 201.

[0054] Referring to Figure 3 , Figure 3 is a cross-sectional structure schematic diagram of another embodiment of the flavoring device in the electronic atomization device shown in Figure 1 . Alternatively, the first leakage prevention pipe 221 and the second leakage prevention pipe 222 are spaced apart. The second leakage prevention pipe 222 is connected to the bottom wall of the cavity 21. One end of the first leakage prevention pipe 221, which is away from the first air hole 203, is located in the second leakage prevention pipe 222, and a buffer cavity 207 is formed between the corresponding end of the first leakage prevention pipe 221 and the corresponding end of the second leakage prevention pipe 222. The buffer cavity 207 communicates with the leakage prevention cavity 206. During the process of the electronic atomization device 100 from upright to upside down, the buffer cavity 207 can store part of the flavoring substrate that enters the leakage prevention cavity 206, thereby avoiding the phenomenon that the part of the flavoring substrate is immersed in the first air hole 204 after being upside down and leaks from the first air hole 204 again when being upright again.

[0055] It can also be understood that the top end of the first leakage prevention pipe 221 is spaced apart from the top end of the leakage prevention cavity 206, and the distance therebetween is 1-20 mm, preferably 5-10 mm, so as to avoid the flavoring substrate in the leakage prevention cavity 206 from leaking from the first air hole 204.

[0056] In the above embodiment, the end of the first leakage prevention pipe 221 is connected to the first air hole 203, and the end of the second leakage prevention pipe 222 is connected to the boss on the bottom wall of the cavity 21.

[0057] The flavoring device 20 further comprises a second leakage prevention member 23 and a shielding member 24. The second leakage prevention member 23 is connected to the top wall of the cavity 21. The shielding member 24 is arranged between the first leakage prevention member 22 and the second leakage prevention member 23. The shielding member 24 separates the first leakage prevention member 22 and the second leakage prevention member 23. The first leakage prevention member 22 communicates the outside atmosphere and the containing cavity 201. The second leakage prevention member 23 connects the aerosol passage 12 and the containing cavity 201.

[0058] In some embodiments, the second leakage prevention member 23 has the same structure as the first leakage prevention member 22, i.e., the structure of the second leakage prevention member 23 is the same as that of the first leakage prevention member 22 described above. The second leakage prevention member 23 adopts the same leakage prevention mode as the first leakage prevention member 22, and thus the description is omitted.

[0059] In the above embodiment, referring to Figures 1 to 3The second leakage prevention piece 23 is a third leakage prevention pipe 23 connected to the second air hole 202. The third leakage prevention pipe 23 extends towards the first leakage prevention piece 22 and has a gap with the first leakage prevention piece 22. By arranging the third leakage prevention pipe 23 on the second air hole 202, the risk of leakage of the flavoring substrate from the second air hole 202 is reduced.

[0060] In daily use, the electronic atomization device 100 is often used or placed in various postures. Therefore, there is a high risk of leakage of the flavoring substrate from the second air hole 202 when the electronic atomization device 100 is inverted. In the embodiment, the third leakage prevention pipe 23 extending towards the first leakage prevention piece 22 is connected to the second air hole 202 and is spaced apart from the top end of the first leakage prevention piece 22. In another embodiment, the port of the second air hole 202 can extend towards the first leakage prevention piece 22 and be spaced apart from the top end of the first leakage prevention piece 22. In another embodiment, the third leakage prevention pipe 23 or the port of the second air hole 202 extends towards the middle of the containing cavity 201. When the electronic atomization device 100 is inverted, the flavoring substrate is more likely to be stored in the space between the outer wall surface of the third leakage prevention pipe 23 and the inner wall surface of the cavity 21. The third leakage prevention pipe 23 can block the leakage of the flavoring substrate from the second air hole 202.

[0061] Specifically, the third leakage prevention pipe 23 and the first leakage prevention piece 22 further divide the containing cavity 201 into an upper cavity 208 and a lower cavity 209 with the inner wall surface of the cavity 21. Due to the restriction of the third leakage prevention pipe 23 and the first leakage prevention piece 22, the flavoring substrate is more likely to flow between the upper cavity 208 and the lower cavity 209 due to the change in the posture of the electronic atomization device 100. That is, in different use states or different placement states, the flavoring substrate flows between the upper cavity 208 and the lower cavity 209, thereby greatly reducing the risk of leakage of the flavoring substrate from the second air hole 202 and the first air hole 203.

[0062] The shielding piece 24 is arranged between the first leakage prevention piece 22 and the second leakage prevention piece 23. The shielding piece 24 separates the first leakage prevention piece 22 and the second leakage prevention piece 23. The main function of the shielding piece 24 is to change the flow direction of the flavoring substrate during the change in the use posture of the electronic atomization device 100, so as to prevent the flavoring substrate from flowing into the pipe port of the first leakage prevention piece 22 and / or the second leakage prevention piece 23 towards the shielding piece 24.

[0063] Optionally, the first leakage prevention piece 22 and the second leakage prevention piece 23 can be single leakage prevention pipes, and the pipe ports of the two leakage prevention pipes can face the shielding piece 24. One of the first leakage prevention piece 22 and the second leakage prevention piece 23 is a single leakage prevention pipe, and the pipe port of the leakage prevention pipe faces the shielding piece 24.

[0064] Optionally, the shielding member 24 is connected to the end of the first leakproof member 22 facing the second leakproof member 23; or the shielding member 24 is connected to the end of the second leakproof member 23 facing the first leakproof member 22; or the shielding member 24 is spaced apart from the first leakproof member 22 and the second leakproof member 23.

[0065] In other words, the shielding member 24 can be connected to any end of the first leakproof member 22 and the second leakproof member 23 facing each other, or the shielding member 24 is connected to the side wall of the cavity 21 and spaced apart from the first leakproof member 22 and the second leakproof member 23, wherein the edge of the shielding member 24 has a gap with the side wall of the cavity 21, and the gap allows the flavoring substrate to pass through.

[0066] In the embodiment, as shown in Figure 2 and Figure 3 The second leakproof tube 222 includes a tube body 223, and the shielding member 24 is arranged on one end of the tube body 223 facing the third leakproof tube 23. The area of the shielding member 24 projected to the bottom wall of the cavity 21 is larger than the area of the tube body 223 projected to the bottom wall of the cavity 21. In other words, the distance between the edge of the shielding member 24 and the side wall of the cavity 21 is smaller than the distance between the outer wall of the tube body 223 and the side wall of the cavity 21. During the process of being upside down, the flavoring substrate can be prevented from flowing into the third leakproof tube 23, thereby affecting the taste of the aerosol for the user to smoke.

[0067] In the embodiment, the shielding member 24 and the tube body 223 can be integrally formed, which is convenient for assembly and reduces the cost.

[0068] In other embodiments, the shielding member 24 and the tube body 223 form two separate components, which is convenient for maintenance and saves the use cost.

[0069] In other words, the shielding member 24 can shield the pipe opening of the third leakproof tube 23, and further block the flavoring substrate from directly flowing into the pipe opening of the third leakproof tube 23 during the process of flowing from the lower cavity 209 to the upper cavity 208. Therefore, the shielding member 24 can promote the flavoring substrate to flow along the inner wall of the cavity 21 to the upper cavity 208.

[0070] In the embodiment, the first leakproof tube 221, the tube body 223 and the third leakproof tube 23 are coaxially arranged. The shielding member 24 extends to the outside of the tube body 223, so that the shielding member 24 not only shields the pipe opening of the third leakproof tube 23, but also guides the flavoring substrate in liquid state, granular state or solid-liquid mixed state to flow along the inner wall of the cavity 21, thereby avoiding the leakage from the second air hole 202.

[0071] The side of the shielding member 24 facing the second air hole 202 is an arc surface protruding outward, so as to guide the flavoring substrate to fall back to the accommodating cavity 201, and avoid the flavoring substrate from gathering on the side of the shielding member 24 facing the second air hole 202. Figure 2As shown, the side of the shielding member 24 facing the first air hole 203 is a concave arc surface, thereby forming a storage space. When the electronic atomization device 100 is inverted, this storage space can serve as a storage space for a portion of the fragrance matrix. When the storage space is filled with the fragrance matrix, the fragrance matrix overflows from the edge of the shielding member 24, forming a parabolic shape that falls away from the shielding member 24. When the electronic atomization device 100 is placed upright, the concave arc surface also serves to reflect airflow. The reflected airflow contacts the fragrance matrix again in the lower cavity 209, allowing the airflow to more fully agitate the fragrance matrix and further produce fragrance.

[0072] Alternatively, as Figure 3 As shown, the side of the shielding member 24 facing the first air hole 203 can also be an outwardly convex arc surface. The outwardly convex arc surface can further guide the dispersed flavoring matrix to flow toward the space outside the edge of the shielding member 24 when the electronic atomization device 100 is inverted, thereby preventing the flavoring matrix from flowing toward the tube mouth of the third leak-proof tube 23.

[0073] The tube body 223 can be a straight tube or a tapered tube. Figure 2 and Figure 3 As shown, the leakage-proof cavity 206 formed between the straight tube and the first leakage-proof tube 221 is relatively small. In the process of being placed upright, the state passed through includes an inclined state and a lying state. In the process of being placed upright to the lying state, the fragrance-enhancing matrix in the leakage-proof cavity 206 can be discharged from the second through hole 205 to the accommodating cavity 201. Therefore, the fragrance-enhancing matrix in the straight tube increases and then decreases, which is beneficial to reducing the risk of leakage of the fragrance-enhancing matrix. Figure 4 As shown, the wall of the conical tube has a slope, which is more conducive to the flavoring matrix in the leakage-proof cavity 206 being guided out from the second through hole 205, thereby avoiding the increased risk of leakage caused by excessive accumulation of flavoring matrix in the leakage-proof cavity 206.

[0074] like Figure 1 As shown, the electronic atomization device 100 further includes a power supply component 30 , which is used to supply power to the atomizer 10 . The flavor enhancer 20 can be disposed between the atomizer 10 and the power supply component 30 .

[0075] Different from the prior art, the application discloses an electronic atomization device. The application sets a flavoring device in the air inlet path of the atomizer, so that the air flow in the air mist channel leading to the atomizer must pass through the flavoring air channel of the flavoring device. Therefore, under the stirring of the air flow, the flavoring substrate in the accommodating cavity of the flavoring device is continuously impacted, and the air flow carries the flavoring substrate odor. The air flow with the flavoring substrate odor enters the atomizer and is mixed with the generated aerosol, so that the taste of the aerosol can be improved, and the phenomenon that the atomization core in the atomizer is easily burned due to the interaction with the flavoring substrate can be avoided. Further, the bottom wall and the top wall of the cavity of the flavoring device are respectively provided with a first leakage prevention member and a second leakage prevention member, and a shielding member is arranged between the first leakage prevention member and the second leakage prevention member. The first leakage prevention member and the second leakage prevention member have a leakage prevention effect, and the shielding member isolates the first leakage prevention member and the second leakage prevention member, thereby being capable of changing the flow direction of the flavoring substrate in the use posture change of the electronic atomization device, avoiding the flow of the flavoring substrate into the pipe opening of the first leakage prevention member and / or the second leakage prevention member towards the shielding member, and further reducing the leakage risk of the flavoring substrate in the flavoring device.

[0076] The above is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the application.
