[0013] In some embodiments, a liquid storage element is disposed in the first liquid storage cavity, and the liquid storage element is used to store the liquid matrix in the first liquid storage cavity and transfer the liquid matrix to the first liquid conducting element.

[0014] In some embodiments, a first outlet channel for the first aerosol to flow through is provided between the first atomization chamber and the air outlet hole, and a second outlet channel for the second aerosol to flow through is provided between the second atomization chamber and the air outlet hole.

[0015] In some embodiments, a fiber absorption element is further included, which is arranged adjacent to the suction nozzle. The fiber absorption element has a first through hole corresponding to the first air outlet channel and a second through hole corresponding to the second air outlet channel.

[0016] In some embodiments, at least a portion of the first air outlet channel and the second air outlet channel comprises a tubular body for aerosol to flow through.

[0017] In some embodiments, the liquid storage member has a first end and a second end oppositely arranged along the length direction of the electronic atomization device, and a side surface extending between the first end and the second end. The liquid storage member also includes a first through hole connecting the first end and the second end, and the first atomization assembly is installed in the first through hole.

[0018] In some embodiments, the first atomization chamber is defined by the first through hole, external air enters the first through hole from the first end and escapes the first through hole from the second end, the first heating element is adjacent to the first end, and the liquid storage member further includes a slit extending from the hole wall of the first through hole to the side, and the slit passes through the end surface of the first end.

[0019] In some embodiments, the liquid storage member further includes a groove disposed on the side surface and extending from the first end to the second end, wherein the groove is in communication with external air.

[0020] In some embodiments, the electronic atomization device also includes a second seal for sealing the first liquid storage chamber and the second liquid storage chamber, and the second seal forms a first air inlet for guiding external air into the first atomization chamber, and a second air inlet for guiding external air into the second atomization chamber.

[0024] In the electronic atomization device provided in the above embodiment, since the first liquid-conducting element is made of a fiber material and the second liquid-conducting element is made of a porous ceramic, the speed at which the first liquid-conducting element transfers the liquid matrix is ​​greater than the speed at which the second liquid-conducting element transfers the matrix. Consequently, under the same power, the amount of smoke in the first aerosol generated by heating and atomizing the first heating element will be larger. Since the second liquid-conducting element transfers the liquid matrix more slowly, the second liquid-conducting element can provide the liquid matrix with a suitable transfer speed to the second heating element for heating and atomizing. This makes the second aerosol generated after heating and atomizing the second heating element more delicate, with a more uniform particle size distribution, a multi-layered taste, and a better degree of flavor restoration of the liquid matrix. Furthermore, the first aerosol and the second aerosol will mix at the air outlet of the mouthpiece, and the user will inhale the mixed aerosol.

[0051] An embodiment of the present application provides an electronic atomization device 100 for atomizing a liquid matrix to generate an aerosol. As shown in Figures 1 and 2, the electronic atomization device 100 includes a nozzle 10, a main shell 20 and a base 30. The main shell 20 has a first end and a second end that are relatively arranged along the length direction of the electronic atomization device 100. The nozzle 10 is installed at the first end and the base 30 is installed at the second end. The nozzle 10 is provided with an air outlet 11 for the aerosol to escape from the electronic atomization device 100. The user can inhale the aerosol by suctioning on the air outlet 11. At least a portion of the base 30 extends into the main shell 20 to provide support for the parts in the main shell 20. The base 30 is also provided with an air inlet 31 for the outside to enter the electronic atomization device 100.

[0052] As shown in Figures 3 and 4, a liquid storage portion 21 is provided in the main housing 20. The liquid storage portion 21 includes a housing 22. The housing 22 has a first end 221 and a second end 222 that are oppositely disposed, and a chamber 223 extending between the first end 221 and the second end 222. The housing 22 also includes a first partition plate 224 extending between the first end 221 and the second end 222. The first partition plate 224 further divides the chamber 223 into a first chamber 2231 and a second chamber 2232 that are spaced apart. The first chamber 2231 serves as a first liquid storage chamber for storing a portion of the liquid matrix of the electronic atomization device 100, and the second chamber 2232 serves as a second liquid storage chamber for storing another portion of the liquid matrix of the electronic atomization device 100. When the liquid matrix stored in the electronic atomization device 100 is liquid medicine, the electronic atomization device 100 can be used as a medical atomizer for treating respiratory diseases; and when the liquid matrix stored in the electronic atomization device 100 is electronic cigarette atomizing liquid, the electronic atomization device 100 can be used as an electronic cigarette.

[0053] Please continue to refer to Figure 3. A liquid storage member 231 is provided in the first liquid storage chamber 2231. The liquid storage member 231 is used to absorb and store the liquid matrix in the first liquid storage chamber 2231. A first atomization assembly is provided in the liquid storage member 231. The first atomization assembly includes a first liquid guiding element 232 and a first heating element 233. The first liquid guiding element 232 is a hollow cylindrical body. The first heating element 233 is combined with the inner wall of the first liquid guiding element 232. The first liquid guiding element 232 is in contact with the liquid storage member 231, so that the liquid matrix in the liquid storage member 231 can be transferred to the first liquid guiding element 232, and then transferred from the first liquid guiding element 232 to the first heating element 233 for heating and atomization to generate a first aerosol.

[0054] The liquid storage member 231 and the second liquid guiding member 232 are both made of fiber materials. Suitable fiber materials can be any one of cotton fibers, non-woven fabrics, or glass fiber ropes. The fiber material has a large number of voids or microporous structures inside, which enables it to absorb the liquid matrix and transfer the liquid matrix. Since the liquid storage member 231 is in contact with the first liquid guiding member 232, the liquid matrix stored in the liquid storage member 231 can be transferred to the first liquid guiding member 232 through the voids or microporous structures inside it, and the first heating element 233 is combined with the first liquid guiding member 232, and then the first liquid guiding member 232 can transfer the liquid matrix to the first heating element 233 through the voids or microporous structures inside it. The first heating element 233 can heat and atomize the liquid matrix to produce a first aerosol.

[0055] As shown in Figures 3 and 6, the liquid storage member 231 has a first through hole 2311 that axially extends through the body thereof. The first atomization assembly is disposed in the first through hole 2311. Specifically, the first heating element 233 utilizes a meshed resistance heating wire, which is formed into a cylindrical shape that matches the first liquid-guiding element 232, thereby facilitating the integration of the meshed resistance heating wire into the inner wall of the first liquid-guiding element 232. The first aerosol generated by atomization by the first heating element 233 is released into the first through hole 2311. In other words, the first through hole 2311 serves as a first atomization chamber for receiving the first aerosol generated by the first heating element 233 heating the atomized liquid matrix.

[0056] In some embodiments, as shown in Figure 12, the first liquid-conducting element 232 is constructed into a cylindrical shape with open ends and a hollow interior. The first liquid-conducting element 232 has a hollow area 2321, and the first heating element 233 is assembled in the hollow area 2321 of the first liquid-conducting element 232 to be combined with the inner wall of the first liquid-conducting element 232.

[0057] A first air outlet channel is defined between the first atomization chamber and the air outlet hole 11. The first air outlet channel is configured to transmit the first aerosol generated by atomization of the first atomization assembly to the air outlet hole 11. Specifically, as shown in Figures 3 and 12, the first air outlet channel includes a first tubular body 2312, at least a portion of which extends into the first through hole 2311. The first tubular body 2312 is hollow, and the first atomization assembly is retained within the first tubular body 2312. A second through hole 23121 is provided in the wall of the first tubular body 2312, so that the first liquid-guiding element 232 in the first atomizing assembly can pass through the second through hole 23121 and contact the liquid storage element 2321 to receive the liquid matrix in the first liquid storage chamber. The first aerosol generated by atomization of the first atomizing assembly is released into the tubular body 2312, and then the tubular body 2312 can transmit the first aerosol. The tubular body 2312 is connected to the air outlet 11, and the first aerosol can be transmitted to the air outlet 11 through the tubular body 2312.

[0058] In some embodiments, as shown in FIG. 12 , the first tubular body 2312 has a hollow area 23122 , and the first atomizing assembly is assembled in the hollow area 23122 of the first tubular body 2312 .

[0059] As shown in Figures 7, 8 and 10, a first sealing member 225 is provided in the second chamber 2232. The first sealing member 225 is made of a flexible material such as silicone or rubber. The first sealing member 225 has an interference fit with the inner wall of the second chamber 2232, so that the remaining part of the second chamber 2232 forms a second liquid storage chamber 2233. The first sealing member 225 then seals the second liquid storage chamber 2233. The first sealing member 225 includes an end face 2251 facing the second liquid storage chamber 2233 and a side wall 2252 extending from the end face 2251 away from the second liquid storage chamber 2233. The end face 2251 and the side wall 2252 define a receiving chamber 2253. The receiving chamber 2253 receives and holds a liquid guide bracket 228. The second atomization assembly 226 is assembled on the liquid guide bracket 228. A liquid guide hole 22511 is formed on the end face 2251 for the liquid matrix in the second liquid storage chamber 2233 to flow through. A liquid guide channel 2281 is formed on the liquid guide bracket 228. The liquid matrix in the second liquid storage chamber 2233 can flow to the second atomization assembly 226 through the liquid guide hole 22511 and the liquid guide channel 2281 to be atomized to form a second aerosol, as shown by the arrow route R3 in Figure 10.

[0060] As further shown in Figure 11, the second atomization component 226 includes a second liquid-conducting element 2261 and a second heating element 2262 coupled to the second liquid-conducting element 2261. The second liquid-conducting element 2261 is made of porous ceramic and has a large number of microporous structures inside. The second liquid-conducting element 2261 may be roughly but not limited to a block structure in an embodiment. Depending on the usage scenario, it includes a liquid absorption surface 22611 and an atomization surface 22612 relatively arranged along the length direction of the electronic atomization device 100, that is, the upper and lower surfaces of the block-shaped second liquid-conducting element 2261 in Figure 11. The liquid absorption surface 22611 faces the second liquid storage chamber 2233 for absorbing the liquid matrix. The second heating element 2262 is coupled to the atomization surface 22612 for heating the atomized liquid matrix to generate a second aerosol. The liquid matrix can flow to the liquid absorption surface 22611 through the liquid-conducting channel 2281, and flow to the atomization surface 22612 through the internal microporous structure of the second liquid-conducting element 2261.

[0061] The second heating element 2262 is preferably formed on the atomizing surface 22612 by mixing conductive raw material powder with a printing aid into a slurry, printing it according to a suitable pattern, and then sintering it, so that all or most of its surface is tightly bonded to the atomizing surface 22612, with high atomization efficiency, low heat loss, and anti-dry burning or greatly reduced dry burning. In some embodiments, the second heating element 2262 can adopt a variety of other structural forms. For example, the second heating element 2262 can be a sheet heating element with a specific pattern attached to the atomizing surface 22612, or a heating mesh, a disc-shaped heating element formed by a heating wire spiral, a heating film, or other forms; in some examples, the specific pattern can be a serpentine shape. In some embodiments, suitable materials that can be used for the second heating element 2262 include nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium. Therefore, after the liquid matrix is ​​transferred to the atomizing surface 22612 , the second heating element 2262 of the atomizing surface 22612 can heat and atomize the liquid matrix, and release the second aerosol generated after the atomization from the atomizing surface 22612 .

[0062] Continuing with FIG10 , the second chamber 2232 is further provided with a first support seat 227 opposite the atomizing surface 22612. The first support seat 227 is fixedly connected to the liquid guide bracket 228 to support the liquid guide bracket 228. A second atomizing chamber 2271 is defined between the first support seat 227 and the atomizing surface 22612, where the second aerosol generated by the second heating element 2262 heating the liquid matrix is ​​released. The first support seat 227 is also provided with an electrode hole, into which a conductive electrode 2272 is inserted. The conductive electrode 2272 extends longitudinally and abuts the atomizing surface 22612 to electrically connect with the second heating element 2262 on the atomizing surface 22612.

[0063] A second air outlet channel is provided between the second atomizing chamber 2271 and the air outlet hole 11, and the second air outlet channel is used to transmit the second aerosol generated by atomization of the second atomizing assembly 226 to the air outlet hole 11. Specifically, as shown in Figures 3 and 7, the liquid storage portion 21 further includes a second tubular body 229 extending longitudinally in the second liquid storage chamber, and an air vent 22512 is further formed on the end surface 2251 of the first sealing member 225. The air vent 22512 is in fluid communication with the second atomizing chamber 2271. One end of the second tubular body 229 is connected to the air outlet hole 11, and the other end extends into the air vent 22512. Thus, the second aerosol generated by atomization of the second atomizing assembly 226 can be transmitted to the air outlet hole 11 through the second tubular body 229, and then the first aerosol and the second aerosol are mixed at the air outlet hole 11, and the user can inhale the mixed aerosol when inhaling. In summary, the electronic atomization device 100 provided in this embodiment has a first liquid-conducting element 232 made of fiber material and a second liquid-conducting element 2261 made of porous ceramics. The internal micropore structure in the porous ceramics is denser than that of the fiber material. Therefore, the speed at which the first liquid-conducting element 232 transfers the liquid matrix is ​​greater than the speed at which the second liquid-conducting element 2261 transfers the liquid matrix. Therefore, under the same power, the amount of smoke in the first aerosol generated by heating and atomization by the first heating element 233 is larger. Since the second liquid-conducting element 2261 transfers the liquid matrix at a slower speed, the second liquid-conducting element 2261 can provide a liquid matrix with a suitable transfer speed to the second heating element 2262 for heating and atomization, so that the second aerosol generated after the second heating element 2262 is heated and atomized is relatively delicate, the particle size distribution of the second aerosol is relatively uniform, it has a multi-layered taste, and the taste restoration of the liquid matrix is ​​better.

[0064] Moreover, since the first aerosol and the second aerosol will mix at the air outlet 11 of the mouthpiece 10, the mixed aerosol can have the advantages of the large amount of smoke of the first aerosol and the uniform particle size distribution and delicate taste of the second aerosol, and when the user inhales at the air outlet 11, the user's suction taste can be effectively improved. It should be noted that the composition of the liquid matrix stored in the first liquid storage chamber 2231 and the second liquid storage chamber 2233 can be the same, so that the composition of the first aerosol and the second aerosol generated are also the same. In some embodiments, as shown in Figures 3 and 4, the second end 222 of the liquid storage portion 21 is open, and the electronic atomization device 100 also includes a second sealing member 25 installed on the second end 222 and sealing the opening of the second end 222. The second sealing member 25 can also be made of a flexible material such as silicone or rubber. The second sealing member 25 can extend into the chamber 223 through the open portion of the second end 222 and have an interference fit with the inner wall of the housing 22, thereby sealing the opening of the second end 222. The sealing of the second sealing member 25 can prevent the liquid matrix stored in the first chamber 2231 and the second chamber 2232 from leaking out of the liquid storage portion 21.

[0065] In some embodiments, as shown in FIG3 , a first air inlet 251 and a second air inlet 252 are provided on the second sealing member 25. The first air inlet 251 is used to guide external air into the first atomization chamber 2311, and the second air inlet 252 is used to guide external air into the second atomization chamber 2271. When the user inhales at the air outlet 11, external air enters the electronic atomization device 100. A portion of the air enters the first atomization chamber 2311 through the first air inlet 251 to carry the first aerosol in the first atomization chamber 2311 and then transmit it to the air outlet 11 for the user to inhale, as shown by the arrow route R1 in FIG3 ; another portion of the air can enter the second atomization chamber 2271 through the second air inlet 252 to carry the second aerosol in the second atomization chamber 2271 and then transmit it to the air outlet 11 for the user to inhale, as shown by the arrow route R2 in FIG3 . By providing the first air inlet 251 and the second air inlet 252 , sufficient external air can enter both the first atomizing chamber 2311 and the second atomizing chamber 2271 .

[0066] Furthermore, in some embodiments, the first air inlet 251 and the second air inlet 252 have the same diameter, so that external air can evenly enter the first atomization chamber 2311 and the second atomization chamber 2271, which is beneficial to improving the taste of aerosol inhalation.

[0067] In some embodiments, when the user inhales at the air outlet 11, external air enters the electronic atomization device 100 through the air inlet 31, and then part of the external air enters the first atomization chamber 2311 through the first air inlet 251, and another part of the external air enters the second atomization chamber 2271 through the second air inlet 252, that is, the first atomization chamber 2311 and the second atomization chamber 2271 share one air inlet 31.

[0068] In some embodiments, as shown in FIG3 , a second support seat 40 is fixedly provided on the base 30 and is arranged opposite to the second sealing member 25. The second support seat 40 is used to support the battery cell 50 of the electronic atomization device 100. A receiving chamber 41 is defined between the second support seat 40 and the second sealing member 25. The battery cell 50 extends laterally into the receiving chamber 41 to save space occupied by the battery cell 50. Since the speed at which the first liquid-conducting element 232 transfers the liquid matrix is ​​greater than the speed at which the second liquid-conducting element 2261 transfers the liquid matrix, and since the first heating element 233 uses a meshed resistance heating wire to heat the liquid matrix, its heating power is greater than the heating power of the second heating element 2262 under the same voltage input, the liquid matrix in the first liquid storage chamber 2231 is consumed at a faster rate than the liquid matrix in the second liquid storage chamber 2233. In order to prevent the liquid matrix in the first liquid storage chamber 2231 from being consumed prematurely, resulting in a lack of liquid matrix supply to the first heating element 233, and thus causing the first heating element 233 to dry out, in some embodiments, as shown in Figure 3, the volume of the first liquid storage chamber 2231 is larger than the volume of the second liquid storage chamber 2233.

[0069] In some embodiments, as shown in FIG6 , the liquid reservoir 231 has a first end 2313 and a second end 2314 disposed opposite each other in the longitudinal direction, and a side surface 2315 extending between the first end 2313 and the second end 2314. A first through hole 2311 connects the first end 2313 and the second end 2314, thereby longitudinally penetrating the liquid reservoir 231. External air enters the first through hole 2311 from the first end 2313 and escapes from the first through hole 2311 from the second end 2314. A first atomizer assembly is mounted in the first through hole 2311 from the first end 2313. A slit 2316 is provided in the wall of the first through hole 2311, passing through the end surface of the first end 2313 and extending to the side surface 2315. When the first atomizer assembly is mounted in the first through hole 2311, the slit 2316 allows the first through hole 2311 to expand outward, thereby facilitating assembly of the first atomizer assembly into the first through hole 2311.

[0070] In some embodiments, the slit 2316 extends to the end surface of the second end 2314, thereby dividing the liquid reservoir 231 into two parts. In other words, the liquid reservoir 231 is formed by closing the two parts. When the first atomizer assembly needs to be assembled into the liquid reservoir 231, the two parts of the liquid reservoir 231 can be separated, then the first atomizer assembly is assembled into the first through hole 2311, and finally the two parts of the liquid reservoir 231 are closed.

[0071] Furthermore, in some embodiments, as shown in Figures 3 and 7, the liquid storage member 231 further includes a groove 2317 provided on the side surface 2315 and extending from the first end 2313 and the second end 2314 bracket. When the liquid storage member 231 is installed in the first chamber 2231, the groove 2317 and the inner wall of the first chamber 2231 define an air channel, so that the air channel connects the air cavity of the first end 2313 and the second end 2314 of the liquid storage member 231. At the same time, the air channel is connected to the outside air, thereby keeping the air cavity of the first end 2313 and the second end 2314 of the liquid storage member 231 consistent with the external air pressure, thereby preventing the liquid matrix from being consumed in the liquid storage member 231. The negative pressure may cause the liquid matrix in the liquid storage member 231 to be unable to flow smoothly downward to the first heating element 233, thereby causing insufficient liquid supply to the first heating element 233 and causing dry heating.

[0072] Specifically, as shown in FIG9 , a vent hole 2211 is provided on the end surface of the first end 221 of the housing 22, connected to the first chamber 2231. A third sealing member 60 is provided between the nozzle 10 and the liquid storage portion 21 for sealing the first and second air outlet channels. The third sealing member 60 includes a first air hole 61 connected to the vent hole 2211, and a groove 62 connecting the first air hole 61 and the air outlet 11 or the first tubular body 2312. External air can enter the first liquid storage chamber 2231 through the groove 62, the first air hole 61, and the vent hole 2211 to replenish the first liquid storage chamber 2231, as indicated by arrow R4 in FIG9 . It will be readily understood that in other embodiments, the air channel may also be connected to the external air through other structural means.

[0073] In some embodiments, the third seal 60 is disposed adjacent to the air inlet 11 to prevent the first aerosol and the second aerosol from leaking before entering the air outlet 11. In some embodiments, the electronic atomization device 100 further includes a fiber absorption element 70, which is disposed adjacent to the suction nozzle 10. The fiber absorption element 70 is provided with a first through hole 71 and a second through hole 72. The first through hole 71 corresponds to the first air outlet channel for allowing the first aerosol to flow through; the second through hole 72 corresponds to the second air outlet channel for allowing the second aerosol to flow through. When the first aerosol and the second aerosol flow through the fiber absorption element 70, the fiber absorption element 70 can absorb the condensate formed after the high-temperature aerosol in the first air outlet channel and the second air outlet channel condenses, so as to prevent the user from inhaling the condensate when inhaling. Suitable materials for the fiber absorption element 70 can be any one of cotton fiber, non-woven fabric or glass fiber rope.

[0074] In some embodiments, the electronic atomization device 100 may not be provided with the above-mentioned liquid storage component 231. The liquid matrix is ​​directly stored in the first liquid storage chamber, and the liquid matrix contacts the first liquid guiding element 232. The first liquid guiding element 232 absorbs the liquid matrix and transfers it to the first heating element 233. The first heating element 233 heats and atomizes the liquid matrix to produce a first aerosol.

[0075] As shown in FIG. 13 to FIG. 20 , a schematic diagram of an electronic atomization device 100 according to another variation embodiment is shown.

[0076] In some embodiments, the electronic atomization device 100 further includes a second air outlet channel connecting the atomizing surface 226a12 and the air outlet 11a, as shown by the arrow route R2a in Figure 15, so that the second aerosol released from the atomizing surface 226a12 can be delivered to the air outlet 11a through the second air outlet channel. Since the first aerosol generated by the first atomization component is delivered to the air outlet 11a through the first air outlet channel, the air outlet 11a can obtain an aerosol mixed with the first aerosol and the second aerosol. The user can inhale the mixed aerosol by inhaling on the air outlet 11a to improve the taste of the suction.

[0077] In some embodiments, referring again to FIG. 15 , the first air outlet channel includes a first inclined section R1a1, and the second air outlet channel includes a second inclined section R2a1. Both the first and second inclined sections R1a1 and R2a1 are positioned adjacent to the air outlet 11a, extending toward the air outlet 11a and gradually approaching each other. The provision of the first and second inclined sections R1a1 and R2a1 allows for thorough mixing of the first and second aerosols at the air outlet, resulting in a smoother, more refined aerosol and an improved puffing experience.

[0078] It should be noted that the first atomization component and the second atomization component 226a are not limited to the methods in this embodiment. In some other embodiments, the first atomization component and the second atomization component 226a can both be in the form of porous ceramics, or the first atomization component and the second atomization component 226a can both be in the form of fiber materials; or, in some embodiments, the first atomization component and the second atomization component 226a are ultrasonic atomization methods.

[0079] In some embodiments, as shown in FIG15 , the first air outlet passage includes a first straight section R1a2 extending from the first inclined section R1a1 toward the first atomizer assembly. This first straight section R1a2 is the hollow region of the first tubular body 231a2. The second air outlet passage includes a second straight section R2a2 extending from the second inclined section R2a1 toward the second atomizer assembly 226a. The arrangement of the first and second straight sections R1a2 and R2a2 allows the first and second aerosols to flow rapidly toward the air outlet 11a. Furthermore, in some embodiments, the first and second straight sections R1a2 and R2a2 are substantially parallel, and the distance between their central axes is no less than the maximum aperture of the air outlet 11a, thereby reducing the aperture of the air outlet 11a and allowing the first and second aerosols to mix thoroughly within the air outlet 11a.

[0080] In some embodiments, as shown in FIG15 , the nozzle 10a includes a housing 12a , within which is formed a third tubular body 13a extending toward the first inclined section R1a1 and the second inclined section 21 . The third tubular body 13a is hollow and defines the aforementioned air outlet 11a. By disposing the third tubular body 13a within the housing 12a and defining the air outlet 11a by the third tubular body 13a, the diameter of the air outlet 11a can be reduced, thereby allowing the first aerosol and the second aerosol to be fully mixed within the air outlet 11a. Furthermore, the third tubular body 13a includes an air inlet end 13a1 for the first and second aerosols to enter. At least a portion of the inner wall of the third tubular body 13a near the air inlet end 13a1 is curved to guide the first and second aerosols into the third tubular body 13a.

[0081] In some embodiments, as shown in FIG. 15 , the first inclined section R1 a 1 and the second inclined section R2 a 1 are formed by a third seal 60 a .

[0082] Specifically, as shown in FIG20 , the third seal 60a includes first vent holes 63a for the first aerosol to flow through, and second vent holes 64a for the second aerosol to flow through, and the first vent holes 63a and the second vent holes 64a both extend obliquely to form a first inclined section R1a1 and a second inclined section R2a1.

[0083] In some embodiments, as shown in Figures 15 and 17 , the liquid storage portion 21a includes a second tubular body 22a9 that defines a portion of the second air outlet channel. The second tubular body 22a9 is bonded to the first partition plate 223, specifically, the second tubular body 22a9 is connected to the first partition plate 22a4. The second tubular body 22a9 extends longitudinally and defines a portion of the second linear segment R2a2. Because the second tubular body 22a9 is bonded to the first partition plate 22a4, the second linear segment R2a2 and the first linear segment R1a2 are positioned adjacent to each other, thereby bringing the first and second air outlet channels closer together. This allows for sufficient mixing of the first and second aerosols after they respectively escape from the first and second air outlet channels. Furthermore, the bonding of the second tubular body 22a9 to the first partition plate 22a4 also enhances the strength of the second tubular body 22a9.

[0084] Further in some embodiments, as shown in Figures 15 and 17, the liquid storage portion 21a also includes a second partition plate 22a0 spaced apart from the first partition plate 22a4, the first partition plate 22a4 and the second partition plate 22a0 define a accommodating chamber 22aa, the first liquid storage chamber 224 and the second liquid storage chamber 225 are distributed on both sides of the accommodating chamber 22aa, the second tubular body 22a9 extends into the accommodating chamber 22aa, and the second tubular body 22a9 is respectively connected to the first partition plate 22a4 and the second partition plate 22a0, so as to further increase the strength of the second tubular body 22a9, so that the second tubular body 22a9 extends firmly in the accommodating chamber 22aa.

[0085] In some embodiments, as shown in FIG15 , the first straight section R1a1 extends in the first liquid storage chamber 22a31, and the second straight section R2a1 extends between the first liquid storage chamber 22a31 and the second liquid storage chamber 22a32, thereby bringing the first air outlet channel and the second air outlet channel close to each other so that the first aerosol and the second aerosol can be fully mixed after escaping from the first air outlet channel and the second air outlet channel, respectively.

[0086] In some embodiments, as shown in Figure 16, the electronic atomization device 100 includes a bracket 27a, which is used to hold the second atomization component 226a. An arc-shaped airflow channel 27a1 is formed in the bracket 27a. One end of the airflow channel 27a1 is connected to the second straight line segment R2a2, and the other end is connected to the atomization surface 226a12. The second aerosol released from the atomization surface 226a12 can be transmitted to the second straight line segment R2a2 through the arc-shaped airflow channel 27a1, and then transmitted from the second straight line segment R2a2 to the air outlet 11a through the second inclined segment R2a1.

[0087] Specifically, the bracket 27a includes a first bracket 27a2 and a second bracket 27a3 arranged opposite to each other. A holding space (not shown) for holding the second atomization assembly 226a is formed in the first bracket 27a2, and an electrode hole (not shown) is formed in the second bracket 27a3. The electrode hole holds a conductive electrode 227a2 extending longitudinally to the atomization surface 226a12. The conductive electrode 227a2 is electrically connected to the second heating element 226a2 of the atomization surface 226a12 to provide electrical energy to the second heating element 226a2. The second bracket 27a3 provides support for the first bracket 27a2, thereby keeping the first bracket 27a2 fixed. The airflow channel 27a1 is jointly defined by the first bracket 27a2 and the second bracket 27a3.

[0088] In some embodiments, as shown in Figure 15, the first straight section R1a2 extends to the first atomization assembly, and the second atomization assembly 226a is connected to the second straight section R2a1 through the arc-shaped air flow channel 27a1. In order to maintain the air flow rate in the first air outlet channel and the second air outlet channel basically consistent, the aperture of the second air inlet 251a is larger than the aperture of the first air inlet 252a.

[0089] In some embodiments, as shown in FIG15 , the first air outlet channel is located longitudinally above the first atomizer assembly, while the second air outlet channel deviates from the longitudinal above the second atomizer assembly 226 a so that the second air outlet channel is close to the first air outlet channel, thereby facilitating sufficient mixing of the first aerosol and the second aerosol after escaping from the first air outlet channel and the second air outlet channel.

[0090] The electronic atomization device 100 further includes a fiber absorption element 70a, which is located between the first inclined section R1a1, the second inclined section R1a2, and the air outlet 11a. The fiber absorption element 70a has a third through hole 70a3, which connects the first air outlet channel and the air outlet 11a, and the second air outlet channel and the air outlet 11a. Thus, the first aerosol and the second aerosol can flow into the air outlet 11a through the third through hole 70a3.

[0091] In some embodiments, the electronic atomization device 100 includes a main board 80a, on which a controller of the electronic atomization device 100 is disposed. The first atomization component, the second atomization component and the battery cell 50a are all electrically connected to the controller, so that the controller controls the battery cell 50a to provide the first atomization component and the second atomization component with the electrical energy required for atomization.

[0092] Alternatively, in some embodiments, the electronic atomization device 100 may not include the battery cell 50a, but a separate power supply mechanism (not shown) may provide power to the electronic atomization device 100. The electronic atomization device 100 and the power supply mechanism may be connected by a detachable connection method such as a magnetic connection, a snap connection, etc. When the electronic atomization device 100 needs to be used, the electronic atomization device 100 can be connected to the power supply mechanism.
