[0050] See also Figures 2 to 7 , Figure 2 yes Figure 1 A schematic diagram of the structure of the atomizer of the electronic atomization device provided, Figure 3 yes Figure 2 A cross-sectional schematic diagram of the atomizer provided, Figure 4 yes Figure 2 Another cross-sectional schematic diagram of the atomizer provided, Figure 5 yes Figure 2 A schematic diagram of the structure of the atomizer assembly of the provided atomizer, Figure 6 yes Figure 5 A cross-sectional schematic diagram of the atomizer assembly provided, Figure 7 yes Figure 5 Another cross-sectional schematic diagram of an atomizer assembly is provided.

[0051] See also Figures 2 to 4The atomizer 100 includes a housing 1, a mounting base 2 and an atomizing assembly 3. The housing 1 has an air outlet pipe 11 inside. The mounting base 2 is at least partially disposed inside the housing 1 and cooperates with the housing 1 to form a liquid storage chamber 12, which is used to store an aerosol-generating matrix. The mounting base 2 has a receiving chamber 21 inside. The end of the mounting base 2 close to the air outlet pipe 11 has a liquid inlet hole 22 and an air outlet hole 23 spaced apart from each other. The air outlet hole 23 is connected to the air outlet pipe 11, and the liquid inlet hole 22 is connected to the liquid storage chamber 12. The end of the mounting base 2 away from the air outlet pipe 11 has at least one air inlet hole 24 and two electrode holes 25 spaced apart from each other.

[0052] The atomizing assembly 3 is disposed in the accommodating chamber 21 and is in fluid communication with the liquid inlet hole 22. The atomizing assembly 3 cooperates with the side wall of the accommodating chamber 21 to form an atomizing chamber 30. One end of the atomizing chamber 30 is in communication with the air inlet hole 24, and the other end is in communication with the air outlet hole 23. The aerosol-generating substrate in the liquid storage chamber 12 flows to the atomizing assembly 3 through the liquid inlet hole 22, is absorbed and heated by the atomizing assembly 3 to be atomized to generate an aerosol, and the external air enters the inside of the atomizer 100 through the air inlet hole 24, flows to the atomizing chamber 30 and carries the aerosol to the position of the air outlet hole 23, and finally flows to the air outlet pipe 11 to be inhaled by the user.

[0053] For details, see Figures 5 to 7 , the atomization assembly 3 includes a porous matrix 31 and a heating element 32, the porous matrix 31 includes a top surface 311, a bottom surface 312 disposed opposite to the top surface 311, and a circumferential outer side surface between the top surface 311 and the bottom surface 312, and the circumferential outer side surface connects the top surface 311 and the bottom surface 312. The porous matrix 31 can be a porous structure made of porous materials such as porous metal, porous ceramics or porous glass, or a porous structure formed by punching dense materials such as dense ceramics. In the present embodiment, the porous matrix 31 also includes a liquid storage tank 314 recessed from the top surface 311. The porous substrate 31 is in fluid communication with the liquid inlet hole 22, and the aerosol-generating matrix in the liquid storage cavity 12 flows into the porous substrate 31 through the liquid inlet hole 22. Specifically, the aerosol-generating matrix flows into the liquid storage tank 314 of the porous substrate 31, and the aerosol-generating matrix in the liquid storage tank 314 penetrates through the pores inside the porous substrate 31 to the circumferential outer side of the porous substrate 31, so as to be heated and atomized. It can be understood that the liquid storage tank 314 is provided on the top surface 311 of the porous substrate 31, so that the aerosol-generating matrix can penetrate from the liquid storage tank 314 to various surfaces of the porous substrate 31 more quickly, which is more conducive to improving the atomization efficiency.

[0054] The heating element 32 is at least partially disposed on the circumferential outer surface of the porous substrate 31. Specifically, the heating element 32 includes a first portion, which is annular and combined with the circumferential outer surface of the porous substrate 31. The first portion includes a first electrical connection portion 33 and a second electrical connection portion 34 located on two opposite outer surfaces of the porous substrate 31 and spaced from each other, and a first heating portion 35 and a second heating portion 36 located on the other two opposite outer surfaces and spaced from each other, the two ends of the first heating portion 35 are correspondingly connected to the first electrical connection portion 33 and the second electrical connection portion 34, and the two ends of the second heating portion 36 are correspondingly connected to the first electrical connection portion 33 and the second electrical connection portion 34. The heating element 32 can be formed on the porous substrate 31 by printing, vapor deposition, etching or patch technology.

[0055] It can be understood that in this embodiment, by arranging the heating element 32 on the circumferential outer surface of the porous matrix 31, the heating element 32 on the circumferential outer surface of the porous matrix 31 can directly heat the atomized aerosol to generate the matrix, that is, the atomization surface is on the circumferential outer surface of the porous matrix 31. When the external air enters the inside of the atomizer 100, it will directly carry the aerosol generated by heating and atomization by the heating element 32 on the circumferential outer surface of the porous matrix 31 to the position of the air outlet 23. The aerosol does not need to be dispersed to the left and right sides and directly flows to the position of the air outlet 23, reducing the loss of aerosol and avoiding the problem that when the heating element 32 is arranged on the bottom surface 312 of the porous matrix 31, the external air directly vertically impacts the heating element 32, and the aerosol is dispersed to the left and right with the external air and then hits the side wall of the atomizer 100 and then flows to the air outlet 23, resulting in aerosol loss and affecting the atomization taste. At the same time, the first part of the heating element 32 is set to a ring structure, and both ends of the first heating part 35 and the second heating part 36 are respectively connected to the first electrical connection part 33 and the second electrical connection part 34, so that the first heating part 35 and the second heating part 36 are arranged in parallel, which increases the heating area of ​​the heating element 32 and is more conducive to improving the heating efficiency of the heating element 32, thereby improving the atomization efficiency.

[0056] In some embodiments, the first heating portion 35 and the second heating portion 36 can be symmetrically arranged, or randomly spaced along the extension direction of the circumferential outer side surface of the porous matrix 31; the first electrical connection portion 33 and the second electrical connection portion 34 can also be symmetrically arranged, or the first electrical connection portion 33 and the second electrical connection portion 34 can also be randomly spaced along the extension direction of the circumferential outer side surface of the porous matrix 31. As long as the two ends of the first heating portion 35 can achieve stable electrical connection with the first electrical connection portion 33 and the second electrical connection portion 34, respectively, and the two ends of the second heating portion 36 can achieve stable electrical connection with the first electrical connection portion 33 and the second electrical connection portion 34, respectively, so that the first heating portion 35 and the second heating portion 36 are arranged in parallel. In other examples, at least part of the first electrical connection portion 33 and at least part of the second electrical connection portion 34 extend from the outer side surface of the porous matrix 31 to the bottom surface 312 or the top surface 311, thereby providing a contact area abutting against the electrode 4.

[0057] In some embodiments, the porous matrix 31 is a rectangular parallelepiped, and the circumferential outer side of the porous matrix 31 includes a first side 315 and a second side 316 arranged opposite to each other along the first direction, and a third side 317 and a fourth side 318 arranged opposite to each other along the second direction. The first electrical connection portion 33 and the second electrical connection portion 34 are correspondingly attached to the first side 315 and the second side 316 of the porous matrix 31, and the first heat generating portion 35 and the second heat generating portion 36 are correspondingly attached to the third side 317 and the fourth side 318 of the porous matrix 31. By respectively arranging the first heating part 35 and the second heating part 36 on two opposite side surfaces, and respectively arranging the first electrical connection part 33 and the second electrical connection part 34 on the other two opposite side surfaces, the third side surface 317 and the fourth side surface 318 of the porous matrix 31 are atomizing surfaces, and the atomizing surfaces heat the atomized aerosol to generate a matrix. The third side surface 317 and the fourth side surface 318 of the porous matrix 31 and the side wall of the accommodating cavity 21 form an atomizing cavity 30. The aerosol generated by atomization is carried by the external air and directly flows to the position of the air outlet 23 through the gap between the third side surface 317 and the fourth side surface 318 and the side wall of the accommodating cavity 21, thereby reducing the loss of aerosol and improving the atomized taste.

[0058] In some embodiments, the first heating portion 35 and the second heating portion 36 are symmetrically arranged, and the first electrical connection portion 33 and the second electrical connection portion 34 are symmetrically arranged, so that the current flowing through the first heating portion 35 and the second heating portion 36 can be more uniform, and the heating atomization efficiency of the third side 317 and the fourth side 318 of the porous matrix 31 is more consistent, so that the atomization effect of the atomization component 3 is more uniform, which is more conducive to improving the atomization taste, thereby improving the atomization performance of the atomizer 100.

[0059] In other embodiments, the porous matrix 31 can also be set to other shapes, for example, the porous matrix 31 can be set to any shape such as a cylinder, an elliptical cylinder, a prism, a pentagonal prism, a hexagonal prism, a heptagonal prism, etc., and the first part of the annular heating element 32 is set on the circumferential outer surface of the porous matrix 31, so that the atomization surface of the atomization assembly 3 is on the circumferential outer surface of the porous matrix 31 to reduce the loss of aerosol. The first heating portion 35 and the second heating portion 36 can also be set asymmetrically, and the first electrical connection portion 33 and the second electrical connection portion 34 can also be set asymmetrically. For example, the first heating portion 35 and the first electrical connection portion 33 can be set on the third side 317 at the same time, the second electrical connection portion 34 is still set on the second side 316, and the second heating portion 36 is still set on the fourth side 318, as long as the heating element 32 can heat the atomized aerosol generating matrix to generate aerosol when electrically connected to the power supply assembly 200.

[0060] In some embodiments, in the direction from the bottom surface 312 to the top surface 311 of the porous substrate 31, the width of the first heating portion 35 and the second heating portion 36 are both smaller than the width of the first electrical connection portion 33 and the second electrical connection portion 34. It can be understood that the first electrical connection portion 33 and the second electrical connection portion 34 are used to achieve electrical connection with the power supply assembly 200, so that the atomization assembly 3 can be electrically connected to the power supply assembly 200. The first heating portion 35 and the second heating portion 36 are used to heat the aerosol-generating matrix in the atomized porous substrate 31. The width of the first heating portion 35 and the second heating portion 36 are both smaller than the width of the first electrical connection portion 33 and the second electrical connection portion 34, so that when the current flows from the first electrical connection portion 33 to the second electrical connection portion 34, heat is generated at the positions of the first heating portion 35 and the second heating portion 36. The third side surface 317 and the fourth side surface 318 of the porous substrate 31 are atomization surfaces, thereby heating the atomized aerosol-generating matrix. In other embodiments, the width of the first heating portion 35 and the second heating portion 36 may also be greater than the width of the first electrical connection portion 33 and the second electrical connection portion 34, so that when the heating element 32 is electrically connected to the power supply assembly 200, the current can generate heat at the positions of the first electrical connection portion 33 and the second electrical connection portion 34 when passing through the heating element 32, so that the first side surface 315 and the second side surface 316 of the porous matrix 31 can serve as the atomization surface to heat the atomized aerosol to generate the matrix.

[0061] In some embodiments, see Figure 5 and Figure 7, the first heating portion 35 includes a first heating area 351 and two first connecting areas 352, and the two first connecting areas 352 are respectively connected to the two ends of the first heating area 351. The first heating area 351 includes a plurality of first sub-heating areas 353, and the plurality of first sub-heating areas 353 are arranged at intervals in the direction from the bottom surface 312 to the top surface 311 of the porous substrate 31, and the two ends of the plurality of first sub-heating areas 353 are respectively connected to the two first connecting areas 352. It can be understood that the first heating portion 35 is configured to include the first heating area 351 and the two first connecting areas 352, and the first heating area 351 is connected between the two first connecting areas 352, so that the heating area of ​​the first heating portion 35 of the heating element 32 can be more concentrated, forming a better temperature field distribution, and the atomization efficiency is higher. Moreover, the first heating zone 351 is configured to include a plurality of first sub-heating zones 353 spaced apart in a direction from the bottom surface 312 to the top surface 311 of the porous matrix 31, so that a plurality of parallel current paths are formed in the first heating zone 351, thereby effectively increasing the heating area of ​​the first heating zone 351 and further improving the heating efficiency and atomization efficiency of the heating element 32.

[0062] The second heating portion 36 also includes a second heating area 361 and two second connection areas (not shown), the two second connection areas are respectively connected to the two ends of the second heating area 361, and the second heating area 361 includes a plurality of second sub-heating areas 362, the plurality of second sub-heating areas 362 are arranged at intervals in the direction from the bottom surface 312 to the top surface 311 of the porous matrix 31, and the two ends of the plurality of second sub-heating areas 362 are respectively connected to the two second connection areas. Similarly, the above arrangement can also make the heating area of ​​the second heating portion 36 of the heating element 32 more concentrated, forming a better temperature field distribution and a higher atomization efficiency; moreover, the second heating area 361 is arranged to include a plurality of second sub-heating areas 362 arranged at intervals in the direction from the bottom surface 312 to the top surface 311 of the porous matrix 31, so that a plurality of parallel current paths are formed in the second heating area 361, which effectively increases the heating area of ​​the second heating area 361, and further improves the heating efficiency and atomization efficiency of the heating element 32.

[0063] In some embodiments, Figure 5 and Figure 7As shown, the first heating zone 351 includes two mutually spaced first sub-heating zones 353, both of which extend in an arc shape along the first side surface 315 toward the second side surface 316, and the two first sub-heating zones 353 are symmetrically arranged. The second heating zone 361 includes two mutually spaced second sub-heating zones 362, both of which extend in an arc shape along the extension direction of the first side surface 315 toward the second side surface 316, and the two second sub-heating zones 362 are symmetrically arranged. The first heating zone 351 and the second heating zone 361 have the same shape. Preferably, the first heating zone 351 and the second heating zone 361 are symmetrically arranged, so that the atomization efficiency of the third side surface 317 and the fourth side surface 318 of the porous matrix 31 is more consistent and the atomization is more uniform.

[0064] In other embodiments, the first heating zone 351 may include other numbers of first sub-heating zones 353, and the second heating zone 361 may include other numbers of second sub-heating zones 362, for example, three, four, five, or any other number, and the number of first sub-heating zones 353 may be inconsistent with the number of second sub-heating zones 362. The first sub-heating zones 353 and the second sub-heating zones 362 may also be set in any other shape, for example, a Z shape, an S shape, or any other shape, and the shapes of the first sub-heating zones 353 and the second sub-heating zones 362 may also be inconsistent, and the first heating zone 351 and the second heating zone 361 may also be set asymmetrically. Alternatively, only the first heating part 35 may include the first heating zone 351, and the first heating zone 351 may include multiple first sub-heating zones 353; or, only the second heating part 36 may include the second heating zone 361, and the second heating zone 361 may include multiple second sub-heating zones 362; or, the first heating zone 351 may include only one first sub-heating zone 353, and the second heating zone 361 may include only one second sub-heating zone 362; or, the first connecting zone 352 and / or the second connecting zone may not be provided, and both ends of the multiple first sub-heating zones 353 may be directly connected to the first electrical connecting part 33 and the second electrical connecting part 34, respectively, and both ends of the multiple second sub-heating zones 362 may be directly connected to the first electrical connecting part 33 and the second electrical connecting part 34, respectively.

[0065] In some embodiments, see Figures 5 to 7The porous matrix 31 is a rectangular parallelepiped, and the liquid reservoir 314 is a rectangular groove arranged on the top surface 311 of the porous matrix 31. The distance between the inner wall surface of the liquid reservoir 314 and the circumferential outer side surface corresponding to the first heating portion 35 and the second heating portion 36 is substantially equal, that is, the distance between the inner wall surface of the liquid reservoir 314 and the third side surface 317 and the fourth side surface 318 is substantially equal. It can be understood that substantially equal means that the error is within a certain range, for example, the error is within a range of 10%. In one embodiment, the rectangular groove has four inner wall surfaces, and the distances between the four inner wall surfaces of the rectangular groove and the circumferential outer side surface of the porous matrix 31 corresponding thereto are substantially equal, that is, the rectangular groove is coaxially arranged with the porous matrix 31. It can be understood that the liquid storage tank 314 is set as a rectangular groove, and the distances between the four inner wall surfaces of the rectangular groove and the corresponding circumferential outer side surfaces of the porous matrix 31 are basically equal, so that the aerosol generating matrix flowing into the liquid storage tank 314 can flow more evenly to the four outer side surfaces of the porous matrix 31, thereby making the atomization rates of the third side 317 and the fourth side 318 of the porous matrix 31 more consistent, making the atomization of the atomization component 3 more uniform, and being more conducive to improving the atomization taste.

[0066] In some embodiments, the heating element 32 may further include a second portion, the second portion of the heating element 32 includes a third heating portion (not shown), the third heating portion is arranged on the bottom surface 312 of the porous matrix 31, and the two ends of the third heating portion are respectively connected to the first electrical connection portion 33 and the second electrical connection portion 34. By further arranging the third heating portion on the bottom surface 312 of the porous matrix 31, when the first electrical connection portion 33 and the second electrical connection portion 34 are electrically connected to the power supply assembly 200, the third heating portion generates heat, which can make the heating area of ​​the heating element 32 larger, and further improve the atomization efficiency of the atomization assembly 3. The distance between the bottom wall of the rectangular groove and the bottom surface 312 of the porous matrix 31 can be equal to the distance between the inner wall surface of the rectangular groove and the circumferential outer side surface of the corresponding porous matrix 31, so as to make the atomization more uniform. The third heating part may also include a third heating zone and two third connecting zones. The third heating zone may include multiple third sub-heating zones. The multiple third sub-heating zones are spaced apart along the direction of the third side surface 317 toward the fourth side surface 318, and both ends of the multiple third sub-heating zones are electrically connected to the two third connecting zones respectively. Alternatively, the third connecting zone may not be set, and both ends of the multiple third sub-heating zones are directly electrically connected to the first electrical connecting part 33 and the second electrical connecting part 34 respectively.

[0067] In other embodiments, the heating element 32 may not include the second part, that is, the heating element 32 does not include the third heating part, and the heating element 32 may only include the annular first part, and the atomized aerosol generating matrix is ​​heated only by the heating element 32 on the circumferential outer surface of the porous matrix 31.

Figure 8 and Fig. 9 As shown, the liquid inlet 22 and the air outlet 23 are arranged on the top seat 26, the air inlet 24 and the electrode hole 25 are arranged on the base 27, and the top seat 26 and the base 27 cooperate to form a receiving chamber 21, wherein the top seat 26 and the base 27 can be connected by snap connection, welding, etc. The atomizer assembly 3 is arranged in the receiving chamber 21, and a plurality of support columns 271 are arranged on the surface of the base 27 close to the top seat 26, and the porous matrix 31 of the atomizer assembly 3 is arranged in contact with the support column 271 at one end close to the base 27, so that the support column 271 of the base 27 supports and fixes the porous matrix 31 of the atomizer assembly 3.

[0070] like Fig. 9 As shown, the surface of the base 27 near the top seat 26 is provided with four support columns 271, and the four support columns 271 are arranged corresponding to the four vertex angles of the porous matrix 31 near one end of the base 27, and the end of the porous matrix 31 near the base 27 is contacted with the four support columns 271, so that the porous matrix 31 is supported by the four support columns 271. Specifically, the surface of the four support columns 271 near the top seat 26 is provided with limiting grooves 272, and the four vertex angles of the porous matrix 31 near one end of the base 27 are arranged in the limiting grooves 272 of the four support columns 271 in a one-to-one correspondence, and the surface of the porous matrix 31 near the base 27 is contacted with the bottom wall of the limiting groove 272, and the four limiting grooves 272 limit the four vertex angles of the porous matrix 31, and the bottom wall of the limiting groove 272 supports the porous matrix 31, and the base 27 completes the fixing of the atomizing assembly 3, which is more convenient to realize the assembly connection with the atomizing assembly 3.

[0071] The atomizer 100 further includes two electrodes 4. The base 27 is provided with two electrode holes 25 spaced apart from each other. The two electrodes 4 are respectively and correspondingly arranged in the two electrode holes 25. One electrode 4 is electrically connected to the first electrical connection portion 33 of the heating element 32 of the atomizer assembly 3, and the other electrode 4 is electrically connected to the second electrical connection portion 34 of the heating element 32 of the atomizer assembly 3, so that the power supply assembly 200 and the atomizer assembly 3 can be electrically connected. Specifically, as Figure 3 and Fig. 9 As shown, the two electrode holes 25 are arranged at intervals along the extension direction from the first side 315 of the porous matrix 31 to the second side 316, and the two electrode holes 25 are arranged at intervals along the width direction of the atomizer 100, thereby providing sufficient space for the horizontal installation of the porous matrix 31. One of the electrode holes 25 is arranged adjacent to the first side 315 of the porous matrix 31, and the other electrode hole 25 is arranged adjacent to the second side 316 of the porous matrix 31. The two electrodes 4 are respectively arranged in the two electrode holes 25. In this embodiment, the side of one electrode 4 abuts the first electrical connection portion 33 of the first side 315, and the side of the other electrode 4 abuts the second electrical connection portion 34 of the second side 316, so that the electrode 4 is stably electrically connected to the atomizer assembly 3, forming a closed circuit. In other embodiments, the electrical connection between the power supply assembly 200 and the atomizer assembly 3 can also be achieved by other structural members or methods.

[0072] like Figure 8 As shown, the air outlet 23 and the liquid inlet 22 are spaced apart at one end of the top seat 26 close to the air outlet pipe 11, the top seat 26 is provided with two liquid inlet holes 22, and the two liquid inlet holes 22 are spaced apart on both sides of the air outlet 23. The side wall of the top seat 26 is provided with a notch 261 at the position corresponding to the third side 317 and the fourth side 318 of the porous substrate 31, and the atomization chamber 30 is connected with the air outlet 23 through the notch 261. In this embodiment, the end of the base 27 away from the top seat 26 is provided with two air inlet holes 24, and the two air inlet holes 24 are spaced apart. Specifically, as shown in FIG. Figure 4 and 9 As shown, the two air inlet holes 24 are respectively arranged corresponding to the positions of the third side surface 317 and the fourth side surface 318 of the porous substrate 31. The third side surface 317 and the fourth side surface 318 of the porous substrate 31 are set as atomization surfaces, and the aerosol generated by heating and atomization by the first heating portion 35 of the third side surface 317 and the second heating portion 36 of the fourth side surface 318 overflows into the atomization chamber 30, and the external air enters the inside of the atomizer 100 through the two air inlet holes 24, and carries the aerosol in the atomization chamber 30 along a direction substantially parallel to the third side surface 317 and the fourth side surface 318, flows through the notch 261 of the side wall of the top seat 26, and then flows to the position of the air outlet hole 23, and finally flows through the air outlet pipe 11 to be inhaled by the user.

[0073] In this embodiment, the aerosol generated by atomization will immediately flow to the position of the air outlet 23 along with the external air, avoiding the problem of aerosol loss and affecting the taste caused by the collision of the aerosol with the side wall of the mounting seat 2 or the inner surface of the housing 1, thereby improving the aerosol utilization rate and ensuring the atomization taste. It can be understood that setting two liquid inlet holes 22 can speed up the liquid drop rate of the aerosol generating matrix, setting two air inlet holes 24, and the two air inlet holes 24 are respectively set corresponding to the third side 317 and the fourth side 318, which can also speed up the air intake rate, thereby speeding up the flow speed of the aerosol, more effectively reducing the loss of the aerosol, and at the same time, it is also conducive to more uniform atomization.

[0074] In other embodiments, the liquid inlet hole 22 may be set to any number such as one, three, or the like, the air inlet hole 24 may be set to any number such as one, three, or four, and the position of the air inlet hole 24 may not correspond to the third side surface 317 and the fourth side surface 318, as long as the liquid inlet hole 22 is connected to the atomization assembly 3 and the air inlet hole 24 is connected to the atomization chamber 30.

The atomizer assembly 3 further includes a second seal 6, which is annular and correspondingly arranged on one side of the top surface 311 of the porous matrix 31 close to the top seat 26, and the second seal 6 is arranged around the liquid storage tank 314 of the porous matrix 31. The second seal 6 can seal between the porous matrix 31 and the top seat 26, so as to prevent the aerosol generating matrix in the liquid storage chamber 12 from leaking when flowing to the liquid storage tank 314 of the porous matrix 31, and also prevent the aerosol generating matrix in the liquid storage tank 314 from leaking.
