[0046] For ease of understanding the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions used in this specification are for illustrative purposes only.

[0047] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0048] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] An embodiment of the present invention provides an electronic atomization device 300, the structure of which is shown in Figure 1 and includes: an atomizer 100 that stores a liquid matrix and vaporizes it to generate an aerosol; and a power supply assembly 200 that powers the atomizer 100. The liquid matrix can be, for example, a liquid such as e-liquid or a medicine solution; herein, the liquid matrix can also be referred to as a liquid, vaporization can also be referred to as atomization, and the aerosol can also be referred to as smoke, aerosol or atomized gas.

[0050] In an alternative embodiment, for example Figure 1As shown, the power supply component 200 includes a receiving cavity 270 disposed at one end along the longitudinal direction for receiving and accommodating at least a portion of the atomizer 100, and a first electrical contact 230 at least partially exposed on the inner surface of the bottom of the receiving cavity 270, which is used to form an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply component 200, thereby powering the atomizer 100.

[0051] According to Figure 1 In the preferred embodiment shown, a second electrical contact 64 is provided at the end of the atomizer 100 opposite to the power supply component 200 along the longitudinal direction. Thus, when at least a portion of the atomizer 100 is received within the receiving cavity 270, the second electrical contact 64 forms electrical conduction by contacting and abutting against the first electrical contact 230.

[0052] A seal 260 may be provided within the power supply component 200, and at least a portion of the internal space of the power supply component 200 is separated by this seal 260 to form the above-mentioned receiving cavity 270. Figure 1 In the preferred embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply component 200 and is made of a flexible material, thereby preventing the liquid matrix seeping from the atomizer 100 into the receiving cavity 270 from flowing towards components such as the controller 220 and the sensor 250 inside the power supply component 200.

[0053] In Figure 1 In the preferred embodiment shown, the power supply component 200 may further include a battery cell 210 near the other end relative to the receiving cavity 270 along the longitudinal direction for power supply; and a controller 220 disposed between the battery cell 210 and the receiving cavity. The controller 220 can operably direct current between the battery cell 210 and the first electrical contact 230.

[0054] The power supply component 200 may further include a sensor 250 for sensing the suction airflow generated when the atomizer 100 is being puffed. Thus, the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of this sensor 250.

[0055] Furthermore, in Figure 1 In the preferred embodiment shown, the power supply component 200 is provided with a charging interface 240 at the other end opposite to the receiving cavity 270 for charging the battery cell 210 after connecting to an external charging device.

[0056] Furthermore, in Figure 1 In the embodiment shown, the atomizer 100 mainly may include: a liquid storage space 91 for storing the liquid matrix; an atomization core assembly 10A for sucking the liquid matrix from the liquid storage space 91 by capillary infiltration and heating the liquid matrix to vaporize and generate an aerosol for inhalation.

[0057] Further referring to Figures 2 to 4 as shown, it shows Figure 1 the structure of a preferred embodiment of the atomizer 100 in. As shown in the figure, the atomizer 100 has a proximal end 110 and a distal end 120 facing away from each other in the longitudinal direction; in use, the proximal end 110 is the end used by the user for suction, and the distal end 120 is the end received into the receiving cavity 270. Specifically, in terms of the external structure, the atomizer 100 includes a main housing 90, and the main housing 90 is generally configured as a hollow cylindrical shape and has an inhalation port 94 at the proximal end 110; it has an open end at the distal end 120, so as to facilitate the assembly of various functional components inside the main housing 90 through the open end.

[0058] In some embodiments, as Figures 4 to 7 shown, the atomizer 100 may include the main housing 90 and the atomization core assembly 10A. The atomization core assembly 10A and the main housing 90 may be connected in cooperation through a buckle 573 and a clamping groove 93. The buckle 573 may be provided on two opposite outer sides of the atomization core assembly 10A, and the clamping groove 93 may be provided on two opposite inner sides of the main housing 90, so that each buckle 573 can be clamped in each corresponding clamping groove 93 during assembly, realizing the installation connection between the atomization core assembly 10A and the main housing 90. Alternatively, the atomization core assembly 10A and the main housing 90 may be connected by an adhesive, and may also be set as a detachable connection method.

[0059] Wherein, the main housing 90 defines a liquid receiving space 91 and has a smoke output channel 92 located inside the main housing 90. For example, the liquid receiving space 91 may be surrounded by the inner surface of the main housing 90, the outer surface of the smoke output channel 92 and the upper surface of the atomization core assembly 10A. Since the main housing 90 defines the liquid receiving space 91, the main housing 90 may also be referred to as an atomization chamber, an oil chamber, etc. The smoke output channel 92 may be a smoke output pipe.

[0060] The flue gas output channel 92 can be formed at the center of the main housing 90 and extend longitudinally, and it can be integrally prepared with the main housing 90 through a mold; the second end 923, which is the upper end of the flue gas output channel 92, forms an air inlet 94, and further outputs the aerosol generated inside the atomizer 100 to the air inlet 94. The end of the first end 921, which is the lower end of the flue gas output channel 92, can have a slotted opening 922, which is opened on the pipe wall of the flue gas output channel 92 and can have a square projection profile; the number of the slotted openings 922 can be two and they can be arranged oppositely. The second end 923 of the flue gas output channel 92 opposite to the first end 921 forms the air inlet 94. The flue gas output channel 92 can be provided with a stop portion 924 at a position adjacent to the first end 921; the stop portion 924 can be an annular stepped surface, which can be a transition surface between a section with a larger diameter of the flue gas output channel 92 and the first end 921 with a smaller diameter; the section with the larger diameter can extend to the second end 923. The stop portion 924 is used for stop cooperation with the upper surface of the second seal 70 (see Figure 8 ) to define the insertion depth of the flue gas output channel 92 into the second seal 70.

[0061] Again, Figures 7 to 9 as shown, the atomization core assembly 10A can include a liquid guiding element 10, a heating element 20, a first seal 30, a support seat 40A, etc. The support seat 40A can be a rigid structure, which is used to house and support the liquid guiding element 10, the heating element 20 and the first seal 30, so that the atomization core formed by the liquid guiding element 10 and the heating element 20 is stably held in the main housing 90. Since the support seat 40A is mainly used to support the atomization core, the support seat 40A can also be called an atomization core support assembly.

[0062] Among them, as shown in combination with Figure 10 , the liquid guiding element 10 can include an atomization surface 11 and a liquid suction surface 12 opposite to the atomization surface 11. The liquid guiding element 10 can be prepared from a material with capillary channels or pores, such as hard or rigid capillary structures made of fiber cotton, porous ceramic body, glass fiber rope, porous glass ceramic, porous glass, etc. The liquid guiding element 10 is in fluid communication with the liquid storage space 91 to absorb the liquid matrix transported from the liquid storage space 91. The atomization surface 11 of the liquid guiding element 10 can be its upper surface facing the flue gas output channel 92, and this upper surface is preferably a plane extending along the cross-section of the main housing 90.

[0063] The heating element 20 is disposed on the atomization surface 11 and is used to heat at least a part of the liquid matrix absorbed by the liquid guiding element 10 when powered on to generate an aerosol, which escapes from the atomization surface 11 and is released into the smoke output channel 92. For example, the heating element 20 can be formed on the atomization surface 11 of the liquid guiding element 10 by means of mounting, printing, deposition, etc. The heating element 20 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, and metal titanium in some embodiments. According to Figure 8 As shown, the heating element 20 is a patterned conductive track in a meandering, circuitous pattern, etc., and can include conductive terminals 21 at both ends; the conductive terminals 21 can be in the form of gaskets, which can have shapes such as square, circular, oval, etc.

[0064] Combined with Figure 11 As shown, the first seal 30 can be located between the liquid guiding element 10 and the bracket side wall 44 of the support base 40A, and is used to seal and isolate the atomization surface 11 and the liquid absorption surface 12, that is, to make the liquid provided by the liquid storage space 91 only enter the liquid guiding element 10 through the liquid absorption surface 12 and then be transported to the atomization surface 11. The first seal 30 can be generally cup-shaped, so that the liquid guiding element 10 can be accommodated in the recess of the cup-shaped first seal 30. The first seal 30 can have a second open end 31, a first closed end 32 opposite to the second open end 31, and a seal side wall 33 extending from the first closed end 32 to the second open end 31; the number of the seal side walls 33 can be multiple. For example, for the first seal 30 with a generally cubic shape, it can include four seal side walls 33. The first seal 30 encloses a storage space through the seal side wall 33 and the first closed end 32 for accommodating the liquid guiding element 10 and exposing the atomization surface 11; for example, the atomization surface 11 can be substantially flush with the second open end 31 and thus exposed to the outside of the first seal 30. The first seal 30 also has a liquid inlet 34 opened on the seal side wall 33, so that the liquid absorption surface 12 is communicated with the outside through the liquid inlet 34 and is further communicated with the liquid storage space 91 during assembly. In some embodiments, the liquid guiding element 10 can be generally flat and is supported and disposed in the first seal 30 through a support structure, so that the liquid absorption surface 12 of the liquid guiding element 10 is communicated with the outside through the liquid inlet 34. The first seal 30 can be made of a sealing silicone material.

[0065] Combined with Figure 10 and Figure 11As shown, after the liquid guiding element 10 is placed inside the first seal 30, the other five surfaces of the liquid guiding element 10 except the atomizing surface 11 will be wrapped by the first seal 30, which can prevent the liquid absorbed by the liquid guiding element 10 from leaking from these surfaces. Therefore, the liquid leakage prevention effect is better. It should be noted here that although the side wall 33 of the seal 30 of the first seal 30 is provided with a liquid inlet 34, the part of these side walls 33 of the seal 30 except the liquid inlet 34 can still play a sealing role, and thus has a liquid leakage prevention effect.

[0066] Further, the number of the liquid inlets 34 can be two; for example, each of the two opposite side walls 33 of the first seal 30 is provided with a liquid inlet 34. This can promote the constant supply of liquid to the liquid guiding element 10.

[0067] In addition, the side walls 33 of the first seal 30 that are not provided with the liquid inlets 34 completely cover the corresponding sides of the liquid guiding element 10. This can achieve the sealing of gas and liquid. For example, it can prevent liquid leakage from these corresponding sides and absorption of external water vapor, etc. The first seal 30 can be in the shape of a cuboid, and the two liquid inlets 34 can be provided in the two opposite side walls 33 of the first seal 30 in the length direction; correspondingly, the two opposite side walls 33 of the first seal 30 in the width direction remain intact without holes.

[0068] In some embodiments, as shown in Figure 11 As shown, a closed annular rib 37 can be provided on the side wall 33 of the first seal 30 that circumferentially surrounds the first seal 30. This can enable the convex rib 37 to be in close contact with the inner wall of the support seat 40A when the first seal 30 containing the liquid guiding element 10 is assembled with the support seat 40A, so as to stably seal the gap between the first seal 30 and the support seat 40A and prevent liquid leakage.

[0069] In some embodiments, as shown in Figure 11 As shown, the second open end 31 of the first seal 30 can be located in a plane, for example, can be aligned with the atomizing surface 11; correspondingly, the convex rib 37 can be provided adjacent to the second open end 31. Alternatively, the second open end 31 of the first seal 30 can have a concave end face, for example, the tops of the two opposite side walls 33 of the first seal 30 in the width direction each have a concave notch, which can facilitate the exposure of a part of the two sides of the liquid guiding element 10 received in the first seal 30, and thus facilitate the removal of the liquid guiding element 10 from the first seal 30; similarly, the convex rib 37 can be provided adjacent to the second open end 31 with such a concave end face, so that the convex rib 37 is no longer in the same plane.

[0070] As shown in Figure 5As shown, the support base 40A can accommodate the liquid guiding element 10, the heating element 20 and the first seal 30; and the support base 40A is cooperatively connected with the main housing 90 such that the atomization surface 11 of the liquid guiding element 10 faces the smoke output channel 92.

[0071] When the atomization surface 11 of the liquid guiding element 10 is arranged to face the smoke output channel 92, since the atomization surface 11 is arranged to face the suction port 94 with its back to the power supply assembly 200, the heating element 20 on the atomization surface 11 generates heat, causing the liquid on the atomization surface 11 to absorb heat and atomize. The generated smoke does not need to bypass the liquid guiding element 10 itself, but directly enters the suction channel of the smoke output channel 92 and reaches the suction port 94 for the user to inhale. This reduces the loss generated when the smoke bypasses the atomization core itself, ensures that there is enough smoke volume to be effectively absorbed by the user per unit time, and thus increases the effective smoke volume generated by the electronic atomization device 300 per unit time. Moreover, the distance from the atomization surface 11 to the suction port 94 is relatively small, making the path that the smoke flows through to the suction port 94 the shortest, which can also reduce the loss of the smoke in the suction channel and further ensure the effective smoke volume generated by the electronic atomization device 300 per unit time.

[0072] In some embodiments, as shown in combination with Figure 10 As shown, the liquid guiding element 10 may include a first wall portion 13 where the atomization surface 11 is located and two second wall portions 14 respectively extending away from the atomization surface 11 from both sides of the first wall portion 13. The surface of the first wall portion 13 located between the two second wall portions 14 forms at least a part of the liquid absorption surface 12. The two second wall portions 14 can be simply support structures; or they can be structures made of the same material as the liquid guiding element 10, such that they can not only support the liquid guiding element 10 in the first seal 30 but also play a liquid guiding role; that is to say, the opposite inner surfaces of the two second wall portions 14 can also be used as a part of the liquid absorption surface 12. It is easy to understand that a laterally extending liquid channel 17 is defined between the two second wall portions 14; after assembly, the liquid channel 17 extends from one liquid inlet 34 of the first seal 30 towards the other liquid inlet 34 and is in communication with the liquid inlet 34; during use, the liquid matrix flowing in through the liquid inlet channel 41 opened in the side wall of the support base 40A enters the liquid channel 17 and is absorbed by the capillary pores in the liquid guiding element 10.

[0073] Furthermore, as shown in combination with Figure 10As shown, the two second wall portions 14 can be connected at their ends away from the first wall portion 13 by a connecting wall 15. By adopting the connecting wall 15, the structural strength of the entire liquid guiding element 10 can be enhanced; moreover, when the connecting wall 15 and the two second wall portions 14 are made of the same porous material as the first wall portion 13, the connecting wall 15 can also play a role in guiding liquid. It can absorb the liquid and transport it to the first wall portion 13 through the second wall portions 14. Additionally, as Figure 10 shown, the connecting wall 15 can only connect a part of the ends of the two second wall portions 14. For example, the length of the connecting wall 15 can be about one-third of the length of the first wall portion 13. Alternatively, the connecting wall 15 can connect all of the ends of the two second wall portions 14. For example, the connecting wall 15 can extend in the length direction and connect all of the ends of the two second wall portions 14 located in the extending direction of the connecting wall 15. It is easy to understand that by providing a through hole extending along its length direction below the atomizing surface 11 of the liquid guiding element 10, the wall surface of such a through hole can be used as the liquid absorbing surface 12. Additionally, such a through hole can be a hole penetrating through the liquid guiding element 10 along its length direction, or a blind hole starting from both ends of the liquid guiding element 10 and ending at the middle position of the liquid guiding element 10.

[0074] Furthermore, in combination with Figure 10 shown, the connecting wall 15 can be arranged parallel to the first wall portion 13. Additionally, both sides of each second wall portion 14 can be transitioned to the ends of the second wall portion 14 through arc surfaces 16; that is to say, chamfered shapes can be provided on both sides of each second wall portion 14, which facilitates the assembly of the liquid guiding element 10 into the first seal 30.

[0075] In some embodiments, in combination with Figure 11 shown, the first seal 30 can be provided with a guiding groove 35 extending from the liquid inlet 34 into the first seal 30. By providing the guiding groove 35, it is beneficial to guide the liquid in the liquid receiving space 91 into the first seal 30 through, for example, capillary action, and avoid the liquid from stagnating at the liquid inlet 34; more specifically, since the liquid guiding element 10 has air exchange performance, external gas may enter the liquid passage 17 under the action of the air pressure difference and flow through the liquid inlet 34 to the liquid receiving space 91, which will meet the liquid input through the liquid receiving space 91 at the liquid inlet 34, thus causing the liquid to stagnate at the liquid inlet 34; while the guiding groove 35 can avoid such stagnation. Further, the guiding groove 35 can be defined by two strip-shaped bodies 36 protruding upward from the first closed end 32 of the first seal 30. The two strip-shaped bodies 36 can extend to abut against the connecting wall 15 of the liquid guiding element 10 assembled in the first seal 30. Additionally, the number of the strip-shaped bodies 36 can also be more than three, such that each adjacent two strip-shaped bodies 36 define a guiding groove.

[0076] In some embodiments, in combination with Figure 5 and Figure 8 as shown, a liquid inlet channel 41 may be provided on the side wall of the support base 40A. The liquid inlet channel 41 is respectively communicated with the liquid storage space 91 and the liquid absorption surface 12 of the liquid guiding element 10. The liquid inlet channel 41 may include a first part extending in the longitudinal direction and communicated with the liquid storage space 91, and a second part communicated with the liquid guiding element 10. Wherein, the second part may be horizontal, or may be inclined downward from the first part towards the liquid guiding element 10. This inclined second part is more conducive to guiding the liquid matrix to flow towards the liquid guiding element 10. In addition, the number of the liquid inlet channels 41 may be two, and they may be respectively arranged on both sides of the support base 40A. It should be noted here that the cross-section of the support base 40A may be square, circular, elliptical, etc. Moreover, even if the cross-section of the support base 40A is circular or elliptical, it can still be divided into, for example, four side parts. For example, for Figure 8 the elliptical support base 40A shown, the two side edges in the length direction may be regarded as two opposite side parts, the two side edges in the width direction may be regarded as the other two opposite side parts, and the two liquid inlet channels 41 are respectively arranged in the two opposite side parts in the length direction.

[0077] In the above embodiment, by providing the liquid inlet channel 41, a liquid such as e-liquid can enter the liquid guiding element 10 through the liquid inlet channel 41, and is upwardly introduced into the atomization surface 11 of the liquid guiding element 10 through capillary action for atomization. The atomization amount of the e-liquid is completely supplied through capillary action, and the liquid will not leak downward during the intermediate process, and the anti-leakage effect is good.

[0078] In some embodiments, in combination with Figure 8 and Figure 16 as shown, a conductive element 60 may be provided on the support base 40A. The number of the conductive elements 60 may be two. Each conductive element 60 may include a first part 61 at least partially extending inside the support base 40A and a second part 62 bent relative to the first part 61 towards the heating element 20 on the liquid guiding element 10 inside the support base 40A. The second part 62 is used for electrically connecting with the conductive terminal 21 of the heating element 20, for example, by abutting contact. At least the second part 62 of the conductive element 60 extends or is exposed outside the support base 40A, and forms an electrical contact 63 for supplying power to the heating element 20. The first part 61 of the conductive element 60 may further include the second electrical contact 64. The part of the first part 61 in the vertical direction and the second part 62 may have the same width, and the part of the first part 61 in the horizontal direction (that is, the part where the second electrical contact 64 is provided) may have a slightly wider width.

[0079] At least a part of the first portion 61 of the conductive element 60 can be molded within the support base 40A such that the second electrical contact 64 is exposed from the bottom of the support base 40A, thereby facilitating electrical connection with the power supply assembly 200. For example, at least a part of the conductive element 60 is buried or embedded within the support base 40A; the conductive element 60 and the support base 40A can be integrally prepared by mold-injection molding or hot pressing and other moldable methods; additionally, the conductive element 60 can be formed by bending a sheet-shaped metal substrate.

[0080] In some embodiments, the conductive element 60 can be made of a metal or alloy material with low resistivity and high conductivity such as gold, silver, copper, etc., and is used to conduct current between the power supply assembly 200 and the heating element 20 during use to supply power to the heating element 20. At least a part of the lower end of the conductive element 60 forms the second electrical contact 64 through, for example, stamping deformation, and at least a part of the upper end can be in a bent shape to form the elastic first electrical contact 63 for electrical connection with the heating element 20, thereby ensuring stable electrical contact with the heating element 20. The surface of the second electrical contact 64 can be flush with the surface of the distal end 120 forming the atomizer 100. The elastic first electrical contact 63 can include a bent V-shaped or U-shaped shape in the figure.

[0081] In some embodiments, in combination Figure 5 and Figure 8 As shown, the support base 40A can define a first receiving space 45 and a second receiving space 51 separated by a partition 431; wherein, an air intake path is formed between the first receiving space 45 and the second receiving space 51, and the air intake path is configured to guide and convey the airflow in the second receiving space 51 to the vicinity of the atomization surface 11 located in the first receiving space 45. During assembly, the first receiving space 45 receives the liquid guiding element 10 such that the atomization surface 11 faces away from the second receiving space 51 and towards the smoke output channel 92. Wherein, the support base 40A can have an open end, and the side wall of the support base 40A and the atomization surface 11 between the atomization surface 11 and the open end define an atomization chamber. Additionally, the air intake path can be at least partially defined by the air intake groove 47 on the support base 40A, and the air intake groove 47 can end at the air intake port 471. The airflow can flow through the second receiving space 51 and the air intake groove 47 in sequence and be conveyed to the atomization surface 11 of the liquid guiding element 10 within the support base 40A through the air intake port 471. The support base 40A can be made into an integral structure or can also be formed by combining split structures.

[0082] In some embodiments, in combination Figure 5 、Figure 8 and Figure 14 As shown, the support base 40A may further be provided with an intake pipe 52, and the intake pipe 52 communicates with the second accommodation space 51 through a plurality of through holes 53. For example, the intake pipe 52 may extend upward from the bottom of the support base 40A toward the second accommodation space 51; the plurality of through holes 53 may be formed in the end wall 54 of the intake pipe 52; in the depth direction of the second accommodation space 51, the end wall 54 is higher than the bottommost part of the second accommodation space 51 and lower than the partition plate 431. In this way, this part of the second accommodation space 51 in the outer direction of the intake pipe 52 actually forms a non-leaking container; thus, even if liquid leaks from the liquid accommodation space 91 or the liquid guiding element 10 into the second accommodation space 51, it will be contained in the second accommodation space 51 and will not leak to the outside of the atomizer 100.

[0083] In addition, as Figure 8 and Figure 14 shown, a plurality of liquid leakage storage grooves 55 may be formed on at least one of the bottom surface and the side surface of the second accommodation space 51. These liquid leakage storage grooves 55 may be recessed from the bottom surface and / or the side surface of the second accommodation space 51, or may be defined by a plurality of ridges provided on the bottom surface and / or the side surface of the second accommodation space 51. By forming these liquid leakage storage grooves 55, the liquid leaking into the second accommodation space 51 can be absorbed and stored by these liquid leakage storage grooves 55, for example, by means of capillary action, and further, the flow of these leaked liquids can be restricted.

[0084] In some embodiments, as combined Figure 8 shown, the support base 40A may include a first bracket 40 and a second bracket 50 that are cooperatively connected. Among them, the partition plate 431, the air inlet 471, and the first accommodation space 45 are formed on the first bracket 40; the second accommodation space 51 is formed on the second bracket 50.

[0085] In some embodiments, as combined Figure 8 , Figure 12 and Figure 13As shown, the first bracket 40 may have a first open end 42, a second closed end 43 opposite to the first open end 42, and a bracket side wall 44. The bracket side wall 44 and the second closed end 43 at least define a first accommodation space 45. During assembly, the liquid guiding element 10 is configured to be able to be placed into the first accommodation space 45 from top to bottom through the first open end 42, so as to be accommodated by the first accommodation space 45, and the atomization surface 11 faces the first open end 42; and the bracket side wall 44 and the atomization surface 11 located between the atomization surface 11 and the first open end 42 of the first accommodation space 45 define an atomization chamber; the atomization chamber is the chamber where the heating element 20 on the atomization surface 11 is located. When the heating element 20 works, the aerosol formed by heating the liquid is directly generated in the atomization chamber, and then is output through the smoke output channel.

[0086] Combined with Figure 8 and Figure 12 As shown, after the liquid guiding element 10 is placed in the first bracket 40, the second closed end 43 of the first bracket 40 can prevent the liquid absorbed by the liquid guiding element 10 from leaking downward, so the liquid leakage prevention effect is better.

[0087] In some embodiments, combined with Figure 12 and Figure 13 As shown, the bracket side wall 44 is provided with the liquid inlet channel 41. The liquid inlet channel 41 is used to communicate with the liquid inlet 34 opened by the first seal 30, and then communicate with the liquid absorption surface 12 of the liquid guiding element 10; for example, one liquid inlet channel 41 may be opened on each of the two opposite bracket side walls 44 of the first bracket 40. Further, a guiding groove 46 may be provided on the channel surface of each liquid inlet channel 41, and the guiding groove 46 is recessed with respect to the adjacent channel surface. The guiding groove 46 is used to align and communicate with the guiding groove 35 of the first seal 30 installed in the first bracket 40, so as to guide the liquid in the liquid accommodation space 91 into the first seal 30 through, for example, capillary action, and then be absorbed by the liquid guiding element 10 by infiltration. The guiding groove 46 may be opened on the channel surface in any direction of the liquid inlet channel 41, and is preferably opened on the channel surface at the bottom, so that the liquid can flow into the first seal 30 through the bottom first under the action of gravity. In addition, combined with Figure 5 As shown, the liquid inlet channel 41 of the bracket side wall 44 may start from the first open end 42 and extend towards the second closed end 43 to a position lower than the atomization surface 11 of the liquid guiding element 10.

[0088] Correspondingly, combined with Figure 9 , Figure 12 and Figure 13As shown, the aforementioned air inlet groove 47 can be provided on the first bracket 40, for example, on the outer surface of the bracket side wall 44. The air inlet groove 47 can start from the second closed end 43 and end at the air inlet 471. On the bracket side wall 44, the air inlet 471 can be formed to penetrate from the outer surface of the bracket side wall 44 to the atomization chamber. Among them, the atomization surface 11 of the liquid guiding element 10 received in the first accommodation space 45 is farther from the first opening end 42 than the air inlet 471; that is to say, when taking the first opening end 42 as a reference, the atomization surface 11 is farther from the first opening end 42 than the air inlet 471, so that the air inlet 471 is higher than the atomization surface 11 of the liquid guiding element 10 received in the first accommodation space 45. Alternatively, the air inlet 471 can be located between the atomization surface 11 and the first opening end 42 and closer to the atomization surface 11, so that the air inlet 471 can be above the atomization surface 11 of the liquid guiding element 10 received in the first accommodation space 45 (including: the air inlet 471 is higher than the atomization surface 11; and, the lowest part of the air inlet 471 is flush with the atomization surface 11). The air inlet groove 47 is used to transport the air flow through the air inlet 471 to the space above the atomization surface 11, that is, to the atomization chamber. In this embodiment, by setting the air inlet 471 higher than the atomization surface 11 of the liquid guiding element 10 received in the first accommodation space 45, liquid leakage from the atomization surface 11 to the air inlet groove 47 through the air inlet 471 can be prevented.

[0089] In some embodiments, the air inlet 471 can be provided with an air flow guiding structure, and the air flow guiding structure is used to guide the air flow from the air inlet path to blow towards the atomization surface 11. For example, in combination with Figure 9 and Figure 13 As shown, the air flow guiding structure can include an inclined surface 472 formed on the first bracket 40 of the support seat 40A and inclined relative to the atomization surface 11. In the direction from the outer surface to the inner surface of the bracket side wall 44, the inclined surface 472 can gradually slope downward to get closer and closer to the atomization surface 11; thus, when the air flow is transported from the air inlet groove 47 to the air inlet 471, it can be guided by the inclined surface 472 towards the atomization surface 11.

[0090] In some embodiments, in combination with Figure 7 , Figure 12 and Figure 13 As shown, a liquid storage buffer groove 48 can be provided on the outer surface of the bracket side wall 44, and the liquid storage buffer groove 48 communicates with the atomization chamber. For example, the liquid storage buffer groove 48 can communicate with the space above the atomization surface 11, that is, with the atomization chamber, through an overflow port 481 opened in the bracket side wall 44.

[0091] In some embodiments, on the first side of the first bracket 40, there is provided a first air inlet groove 47 and two first buffer liquid storage grooves 48; the first air inlet groove 47 is located between the two first buffer liquid storage grooves 48, and the air inlet 471 of the first air inlet groove 47 is located between the overflow ports 481 of the two first buffer liquid storage grooves 48. The first side of the first bracket 40 can be a half side of the first bracket 40, and the half side is located on one side of the central plane passing through the two opposite liquid inlet channels 41.

[0092] Further, on the second side of the first bracket 40, there can also be provided a second air inlet groove 47 and two second buffer liquid storage grooves 48; the second air inlet groove 47 is located between the two second buffer liquid storage grooves 48, and the air inlet 471 of the second air inlet groove 47 is located between the overflow ports 481 of the two second buffer liquid storage grooves 48. Additionally, one of the two first buffer liquid storage grooves 48 can be communicated with one of the two second buffer liquid storage grooves 48; the other of the two first buffer liquid storage grooves 48 can be communicated with the other of the two second buffer liquid storage grooves 48. The second side of the first bracket 40 can be the other half side of the first bracket 40, and the other half side is located on the other side of the central plane passing through the two opposite liquid inlet channels 41.

[0093] Further, in combination with Figure 5 and Figure 12 as shown, the part of the first bracket 40 below the air inlet 471 or the atomization surface 11 actually forms a container that does not leak liquid. Thus, the downward leakage of the liquid therein can be prevented, and therefore the liquid leakage prevention effect is better.

[0094] In some embodiments, in combination with Figure 7 、 Figure 12 and Figure 13As shown, the intake groove 47 and the buffer liquid storage groove 48 can be separated by a partition portion 442, so as to prevent the liquid in the buffer liquid storage groove 48 from entering the intake groove 47. The buffer liquid storage groove 48 can be a capillary groove. By providing the buffer liquid storage groove 48, excessive liquid on the atomization surface 11 can flow through the overflow port 481 into the buffer liquid storage groove 48, so that it can absorb and store these overflowing liquids through, for example, capillary action, thereby avoiding liquid leakage to other parts of the atomizer 100; that is, the buffer liquid storage groove 48 can adsorb and hold the condensate of the aerosol generated by the atomizer 100 to prevent them from seeping outwards. In particular, when the intake groove 47 is located between two buffer liquid storage grooves 48, gas enters the atomization surface 11 of the liquid guiding element 10 from the middle intake groove 47. When there is too much condensate on the atomization surface 11 of the liquid guiding element 10, it can be pushed by the incoming gas to the overflow ports 481 on both sides and enter the buffer liquid storage grooves 48 from the overflow ports 481 on both sides, thereby effectively preventing the condensate from flowing from the intake groove 47 into the second bracket 50 and flowing outside.

[0095] Further, the length of the buffer liquid storage groove 48 can be set to be greater than the circumference of the first bracket 40. For example, the buffer liquid storage groove 48 can adopt a circuitous and connected slot structure, so as to form a longer buffer liquid storage groove 48 on the outer surface of the first bracket 40; in particular, the buffer liquid storage groove 48 can include a plurality of horizontal slots, and two adjacent slots can be connected by a vertical slot; in addition, these vertical slots can be set not to be aligned in the vertical direction, so that the liquid preferably flows from the overflow port 481 from the relatively close horizontal slot to the relatively far horizontal slot in sequence. In addition, the overflow port 481 can be set to be higher than the atomization surface 11 of the liquid guiding element 10 received in the first accommodation space 45.

[0096] In addition, in combination with Figure 5 、 Figure 12 and Figure 13 As shown, the first bracket 40 can be cooperatively connected with the main housing 90, so that the atomization surface 11 of the liquid guiding element 10 received in the first bracket 40 faces the smoke output channel 92, and the atomization surface 11 is in gas flow communication with the first end 921, which is the lower end, of the smoke output channel 92. During assembly, the first bracket 40 can be completely located inside the main housing 90, and the outermost contour surface of the first bracket 40 is basically in fitting contact with the inner surface of the main housing 90; thus, the inner surface of the main housing 90 can be used to seal the lateral openings of the intake groove 47 and the buffer liquid storage groove 48 on the first side of the first bracket 40, and can also seal the lateral openings of the buffer liquid storage groove 48 on the second side of the first bracket 40. In addition, the lateral opening of the intake groove 47 on the second side of the first bracket 40 can be sealed by the second bracket 50.

[0097] In addition, in embodiments including the first bracket 40 and the second bracket 50, the aforementioned conductive element 60 may be disposed on the second bracket 50; for example, the conductive element 60 may be molded on the second bracket 50; more specifically, most of the first portion 61 of the conductive element 60 may be molded within the second bracket 50; and, after the first bracket 40 and the second bracket 50 are assembled, the second portion 62 may be suspended within the first bracket 40. Additionally, as Figure 13 shown, a first mating surface 443 may be provided on the bracket sidewall 44 of the first bracket 40. The first mating surface 443 may be used for stop mating with the second bracket 50.

[0098] In some embodiments, in combination with Figure 8 and Figure 14 shown, the second bracket 50 may include a main body portion 57 and a retaining wall 56, and the retaining wall 56 may be higher than the main body portion 57 and the second receiving space 51 defined by the main body portion 57. The retaining wall 56 is disposed on one side of the second bracket 50. The retaining wall 56 is used for mating connection with the first bracket 40. Additionally, the partition 431 of the first bracket 40 may cover the second receiving space 51. Further in combination with Figure 13 and Figure 14 shown, the top surface 571 of the main body portion 57 and the bottom surface 432 of the second closed end 43 of the first bracket 40 can slide relative to each other, such that the first mating surface 443 and the retaining wall 56 are in stop mating. In this way, the first bracket 40 can be assembled onto the second bracket 50 by lateral movement.

[0099] In some embodiments, in combination with Figure 5 、 Figure 8 and Figure 14 shown, an annular groove 572 may be provided on the main body portion 57 of the second bracket 50, and a sealing ring 59 is disposed within the annular groove 572. The sealing ring 59 may be made of a sealing silicone material. During assembly, the sealing ring 59 is used to form a seal between the main body portion 57 and the main housing 90 to prevent liquid from passing through. Additionally, a magnetic attraction component 58 may be provided in the second bracket 50. The magnetic attraction component 58 may be prepared from a ferromagnetic material such as stainless steel, and thus, after the atomizer 100 is received within the receiving cavity 270, it can be magnetically attracted to the magnetic attraction element provided on the power supply assembly 200, so that the atomizer 100 is stably received within the receiving cavity 270. The magnetic attraction component 58 may be inserted into the mounting hole 581 on the second bracket 50, and the lower end of the magnetic attraction component 58 is flush with the lower end of the second bracket 50.

[0100] In some embodiments, in combination with Figure 13As shown, the bracket side wall 44 of the first bracket 40 may have a vacancy 444, and the vacancy 444 forms the first mating surface 443. For example, among the two opposite sides of the bracket side wall 44, the thickness of one side may be thinner than that of the other side, so as to form the vacancy 444, and the vacancy 444 can be used to accommodate the retaining wall 56 of the second bracket 50.

[0101] In addition, the first mating surface 443 may further include a positioning groove 445, and a positioning block 561 may be provided on the retaining wall 56; the positioning block 561 is used to be inserted into the positioning groove 445 to limit the movement of the first bracket 40 in the direction away from the second bracket 50. The positioning groove 445 may be a groove horizontally extending on the first mating surface 443; correspondingly, the positioning block 561 is also horizontally arranged.

[0102] In some embodiments, in combination Figure 14 As shown, the cross-section of the retaining wall 56 may be semi-circular. That is to say, the cross-section of the main body portion 57 may be an annular shape such as circular, oval, etc., and the retaining wall 56 may be a part extending upward from one side of the central axis plane of the main body portion 57; thus, the semi-circular retaining wall 56 can form a semi-surrounding structure for cooperating with the bracket side wall 44 of the first bracket 40.

[0103] One of the aforementioned air intake grooves 47 may be defined between the first bracket 40 and the second bracket 50, for example, may be at least formed between the retaining wall 56 of the second bracket 50 and the first bracket 40. For another example, the air intake groove 47 may be provided on the outer surface of the bracket side wall 44 of the first bracket 40, and the position of the retaining wall 56 corresponding to the air intake groove 47 may be a surface capable of covering the side opening of the air intake groove 47; thus, when the first bracket 40 and the second bracket 50 are cooperatively connected to each other, the side opening of the air intake groove 47 is covered by the retaining wall 56, so that the gas can only flow from the bottom opening of the air intake groove 47 to the air inlet 471 of the air intake groove 47, and will not flow outwards in the middle part of the air intake groove 47.

[0104] In some embodiments, in combination Figure 8 、 Figure 14 and Figure 16 As shown, the conductive element 60 extends out through the retaining wall 56, so that the retaining wall 56 plays a supporting role on the conductive element 60. Since the conductive element 60 can be made of sheet metal, when its own length is relatively long, it will have a large movement amplitude due to insufficient strength. Therefore, through the support of the retaining wall 56, the first part 61 of the conductive element 60 can be fixed, and further, excessive lateral movement of the second part 62 during assembly can be prevented, and at the same time, sufficient pressing force between the first electrical contact 63 of the second part 62 and the conductive terminal 21 can be ensured.

[0105] In another embodiment, the second bracket 50 may include a stop wall (not shown in the figures) higher than the main body portion 57 and a reinforcing wall (not shown in the figures) higher than the main body portion 57. The conductive element 60 may extend out through the reinforcing wall, such that the reinforcing wall supports the conductive element 60. At this time, the stop wall may be a member separated from the reinforcing wall, and it may only function to stop and cooperate with the bracket side wall 44 of the first bracket 40. In other words, the stop wall 56 shown in, for example, Figure 14 may be divided into at least two separated parts, one part serving as the reinforcing wall and the other part serving as the stop wall in this other embodiment.

[0106] In some embodiments, in combination with Figure 12 and Figure 13 shown, the overflow port 481 formed on the side of the first bracket 40 having the vacant portion 444 may also serve as a through hole 481A. The through hole 481A is arranged higher than the first mating surface 443 and is used for the second part 62 of the conductive element 60 to be inserted and pass through. In combination with Figure 16 shown, the second part 62 of the conductive element 60 is bent towards the through hole 481A relative to the first part 61. The second part 62 may extend into the first bracket 40 through the through hole 481A, and then be electrically connected to the heating element 20 provided on the liquid guiding element 10. As mentioned above, the number of the through hole 481A and the conductive element 60 may both be two. It should be noted here that the overflow port 481 and the through hole 481A described herein may actually be the same through hole, which can not only allow the second part 62 of the conductive element 60 to be inserted and pass through, but also serve as an overflow port for the excessive liquid on the atomizing surface 11 to flow out therefrom. Additionally, in the assembly structure, the second part 62 of the conductive element 60 may only pass through the through hole 481A without contacting the through hole 481A, especially without contacting the lower surface of the through hole 481A. This can prevent the liquid from leaking out along the second part 62 through the through hole 481A.

[0107] In some embodiments, in combination with Figure 8 and Figure 15As shown, the atomization core assembly 10A of the atomizer 100 may further include a second seal 70. The second seal 70 may include a base portion 76 and a skirt portion 71 extending from the periphery of the base portion 76 to one side. A liquid guiding hole 72, a plugging hole 73, and a mounting hole 77 located between the liquid guiding hole 72 and the plugging hole 73 may be provided on the base portion 76. The second seal 70 may be made of sealing silica gel material. The second seal 70 is used to be sleeved on the first bracket 40 of the support seat 40A. At least a part of the first bracket 40 of the support seat 40A is inserted into the main housing 90, so that the skirt portion 71 of the second seal 70 is clamped between the first bracket 40 of the support seat 40A and the main housing 90 to form a seal, and the first end 921 of the smoke output channel 92 is used to be inserted into the plugging hole 73.

[0108] Further, a one-way valve 80A may be provided on the second seal 70. The one-way valve 80A is used to open under the action of a pressure difference. Thus, in the assembled atomizer 100, air can enter the liquid storage space 91 through the one-way valve 80A to avoid a large negative pressure in the liquid storage space 91 due to insufficient liquid, and further enable the liquid to smoothly output from the liquid storage space 91 to the liquid guiding element 10. The one-way valve 80A may be, for example, a duckbill valve or other structures that only allow air to enter the liquid storage space 91 from the outside. In addition, since the atomization surface 11 of the liquid guiding element 10 can be set to face upward, even if the liquid in the liquid storage space 91 leaks through the one-way valve 80A, the leaked liquid will flow onto the atomization surface 11 and will be absorbed by the liquid guiding element 10 or be heated and atomized on the atomization surface 11.

[0109] Further, a drainage portion 75 protruding from the hole wall may be provided in the plugging hole 73 for cooperating with the slot 922 at the end of the smoke output channel 92. For example, the drainage portion 75 may be provided at one end of the plugging hole 73 far from the smoke output channel 92; the drainage portion 75 may include two bumps 751, and a drainage groove 752 is formed between the two bumps 751. When the smoke output channel 92 is inserted into the plugging hole 73, the drainage groove 752 extends into the smoke output channel 92 from outside the smoke output channel 92 for a certain distance. Thus, when the user uses the atomizer 100, if there is condensate in the smoke output channel 92, the condensate can be guided downward by the drainage groove 752 towards the atomization surface 11, avoiding the condensate from dripping onto the atomization surface 11 after condensing into large pieces and having an adverse effect on the atomization quality.

[0110] In some embodiments, in combination with Figure 8 and Figure 15As shown, a valve plate 78 may be provided on the other side of the base portion 76 away from the skirt portion 71, and the valve plate 78 corresponds to the mounting hole 77. A ventilation bracket 80 may be installed in the mounting hole 77; wherein, the ventilation bracket 80 may be a rigid structure and have a ventilation hole 81 (see Figure 5 ); The ventilation bracket 80 is installed in the mounting hole 77 such that the valve plate 78 covers a port 82 of the ventilation hole 81; The valve plate 78 is used to seal or open the port 82 under the action of a pressure difference, thereby acting as a check valve. It is pointed out here that the second seal 70 and the ventilation bracket 80 may form an atomizer seal assembly, which is used to form a seal between the first bracket 40 and the main housing 90; At the same time, the ventilation bracket 80 can strengthen the second seal 70 to prevent the second seal 70 from deforming due to insufficient strength when the first end 921 of the flue gas output channel 92 is inserted into the insertion hole 73.

[0111] In some embodiments, in combination with Figure 8 As shown, the first end 781 of the valve plate 78 is connected to the base portion 76, and the other parts of the valve plate 78 are separated from the base portion 76. In this way, the valve plate 78 can have more flexibility and is convenient to move according to the action of the pressure difference.

[0112] Furthermore, a connecting block 761 and a recess 762 may be provided on the base portion 76. The first end 781 of the valve plate 78 is connected to the connecting block 761, and the recess 762 is located on the side of the connecting block 761 away from the first end 781 of the valve plate 78. By providing the recess 762, the strength of the connecting block 761 connected to the first end 781 can be weakened, so that the valve plate 78 is more easily movable under the action of the pressure difference and is not overly restricted by the base portion 76.

[0113] Furthermore, in combination with Figure 5 and Figure 8 As shown, the ventilation hole 81 may be eccentrically provided on the ventilation bracket 80 such that the ventilation hole 81 is closer to the second end 782 opposite to the first end 781 of the valve plate 78. This setting can make the free end of the valve plate 78 that is easy to move cooperate with the ventilation hole 81.

[0114] In addition, the part of the ventilation bracket 80 in contact with the valve plate 78 may be a boss 83, and the ventilation hole 81 penetrates through the boss 83. Again, as Figure 5 shown, the ventilation hole 81 may have a first section and a second section connected to each other. The first section is close to the valve plate 78, and the cross-sectional dimension of the first section is smaller than that of the second section.

[0115] In addition, in combination with Figure 8 as shown, the ventilation bracket 80 may include a base portion 84 and an annular flange 85 protruding from a side portion of the base portion 84. The base portion 84 may be a column extending uniformly from bottom to top, and its cross-section may be square, circular, elliptical, and similar shapes, especially a rectangle with four arc chamfers. Accordingly, in combination with Figure 14 as shown, the mounting hole 77 may include a first portion 771 for receiving the base portion 84 and a second portion 772 for receiving the annular flange 85. By the stop fit between the annular flange 85 and the second portion 772, the ventilation bracket 80 can be prevented from falling off the second seal 70. At the same time, the mating surface between the annular flange 85 and the second portion 772 also forms a zigzag path in the up and down directions, which can better prevent liquid from leaking therefrom.

[0116] In addition, the number of the mounting holes 77 may be two, the insertion hole 73 may be disposed at the central position of the base portion 76, and one mounting hole 77 is provided between each liquid guiding hole 72 and the insertion hole 73.

[0117] Furthermore, as Figure 15 shown, the two mounting holes 77 may be symmetrically disposed with respect to the insertion hole 73. In addition, as Figure 8 shown, the two connecting blocks 761, the two recesses 762, and the two valve pieces 78 may all be rotationally symmetrically disposed with respect to the insertion hole 73.

[0118] In some embodiments, as Figure 15 shown, the thickness of the base portion 76 where the liquid guiding hole 72 is located may be smaller than the thickness of the base portion 76 where the mounting hole 77 is located. In addition, the upper surface of the base portion 76 may be located in a plane.

[0119] In addition, a stop portion 79 may further be provided at one end of the insertion hole 73 away from the valve piece 78, and the stop portion 79 protrudes inward from the insertion hole 73 so as to abut against the flue gas output channel 92 in the main housing 90. The inner surface of the stop portion 79 may be aligned with the inner surface of the flue gas output channel 92, that is, they may be located in the same cylindrical surface such as a cylindrical surface. In addition, the two convex blocks 751 of the drainage portion 75 may extend upward from the end of the stop portion 79. The inner surfaces of the two convex blocks 751 may also be aligned with the inner surface of the flue gas output channel 92, that is, they may be located in the same cylindrical surface such as a cylindrical surface.

[0120] In some embodiments, as Figure 15As shown, a ridge portion 763 may also be provided on the other side of the base portion 76 away from the valve piece 78, and the ridge portion 763 is located between the insertion hole 73 and the mounting hole 77. For example, the ridge portion 763 may be an arc-shaped structure adjacent to the insertion hole 73; the number of the ridge portions 763 may be two, and they may be oppositely arranged with respect to the insertion hole 73. When the second seal 70 is sleeved on the first bracket 40, the two ends of each ridge portion 763 abut against the inner surface of the first bracket 40. In this way, a step is formed between the ridge portion 763 and the lower surface of the base portion 76, and this step can prevent the formation of a vortex when the atomizer 100 is sucked; in addition, since a receiving space is formed between this step and the first bracket 40, it can be used to receive the condensate accumulated in the atomization chamber when the atomizer 100 is inverted, so as to prevent the condensate from flowing out of the smoke output channel 92 when the atomizer 100 is inverted.

[0121] In some embodiments, in combination Figure 8 and Figure 15 As shown, a step portion 441 may be provided on the side wall of the first bracket 40 of the support seat 40A that defines the first receiving space 45, and the step portion 441 is used to support the portion of the second seal 70 inserted into the first receiving space 45. Thus, when the first end 921 of the smoke output channel 92 is inserted into the insertion hole 73, the second seal 70 can also be supported by the step portion 441 to prevent the second seal 70 from deforming due to loss of support.

[0122] See Figure 17 , which shows a cross-sectional schematic view of an atomizer 100' provided by another embodiment of the present invention. In Figure 17 the embodiment shown, the atomizer 100' and Figures 2 to 16 the atomizer 100 shown in Figures 2 to 16 differ only in terms of the second seal 70, and other structures may be exactly the same. For example, the atomizer 100' may include the same liquid guiding element 10, heating element 20, first seal 30, first bracket 40, second bracket 50, conductive element 60 and main housing 90. However, the second seal 70' in the atomizer 100' may be different from Figure 18As shown, the second seal 70' may be different from the second seal 70 in the ventilation mode. Among them, the second seal 70' may have a ventilation groove 74, and the ventilation groove 74 is used to communicate the atmosphere with the liquid storage space 91 in the main housing 90, and is used to introduce air into the liquid storage space 91 under the action of a pressure difference. When the second seal 70' is sleeved on the first bracket 40, the opening of the ventilation groove 74 facing the first bracket 40 is covered by the inner surface of the first bracket 40, so as to form a gas channel extending from the bottom side to the top side of the second seal 70'. The ventilation groove 74 may be a capillary groove, which may be a groove extending uniformly up and down on one side of the second seal 70'. Further, a plurality of concave portions 741 such as squares or triangles may be provided on two opposite groove surfaces of such a uniformly extending groove up and down. Due to capillary action, the liquid from the liquid storage space 91 can be held in the ventilation groove 74, and only when the negative pressure in the liquid storage space 91 reaches a certain level, the external air can enter the liquid storage space 91 under the action of a pressure difference.

[0123] See Figure 19 , which shows a perspective schematic view of the second bracket 50' provided by another embodiment of the present invention. In Figure 19 the embodiment shown, the second bracket 50' and Figures 2 to 18 the second bracket 50 shown in Figures 2 to 18 are only different in terms of the baffle 56, and other structures may be exactly the same; and, the second bracket 50' can also be applied to Figure 19 the atomizer 100 shown in Figure 13 . Specifically, as Figures 2 to 18When referring to the atomizer 100 shown in the figure, a first air inlet groove 47 formed on the first side of the first bracket 40 forms a first air inlet passage, and the first air inlet passage communicates with the atomizing surface 11 of the liquid guiding element 10 received by the first bracket 40; the groove 562 and the second air inlet groove 47 together form a second air inlet passage, and the second air inlet passage also communicates with the atomizing surface 11. Wherein, the first air inlet passage and the second air inlet passage may have the same passage size; for example, the first air inlet passage and the second air inlet passage may have substantially the same shape, so as to make the air intake on both sides of the first bracket 40 consistent, in order to obtain a better atomizing effect; or, the first air inlet passage and the second air inlet passage may only ensure that the areas of their respective minimum passage cross-sections are the same, which can also make the air intake on both sides of the first bracket 40 consistent.

[0124] See Figure 20 and Figure 21 , which shows a three-dimensional schematic diagram of an atomization core assembly 10B provided by another embodiment of the present invention. In Figure 20 and Figure 21 In the shown embodiment, the atomization core assembly 10B and Figures 2 to 18 The atomization core assembly 10A shown in only differs in the first bracket 40, the second bracket 50 and the conductive element 60, and other structures can be exactly the same. Specifically, as Figure 20 shown, on the first side of the first bracket 40, there is a first air inlet groove 47; the first air inlet groove 47 is used to form a first air inlet passage, and the first air inlet passage communicates with the atomizing surface 11 of the liquid guiding element 10 received by the first bracket 40. As Figure 21 shown, on the second side of the first bracket 40, there is a second air inlet groove 47; a groove 562 is formed in a part of the retaining wall 56 of the second bracket 50 corresponding to the second air inlet groove 47, and the groove 562 and the second air inlet groove 47 together form a second air inlet passage, and the second air inlet passage also communicates with the atomizing surface 11. Similarly, the first air inlet passage and the second air inlet passage may have the same passage size, so as to make the air intake on both sides of the first bracket 40 consistent, thereby obtaining a better atomizing effect. Among them, compared with Figure 19 the second bracket 50'shown, Figure 21 the retaining wall 56 of the second bracket 50 shown has a lower height; correspondingly, the side wall part of the first bracket 40 that defines the slow storage liquid tank 48 on the second side may have a higher height, so as to form a complementary structure with the retaining wall 56. In addition, because Figure 21The shown retaining wall 56 has a relatively low height, and a part of the first portion 61 of the conductive element 60 on the second bracket 50 in the vertical direction can be set to have a wider width than the second portion 62, so that the first portion 61 itself also plays a certain supporting role to prevent the second portion 62 from having excessive lateral movement during assembly. It should be noted here that it is not necessary to set all the vertical portions of the first portion 61 of the conductive element 60 to have a wider width, as long as it is ensured that a part extending from the retaining wall 56 and another part adjacent to this part and embedded in the retaining wall 56 have a wider width. The above has introduced various components of the electronic atomization device 300 and its atomizer 100 of the present invention. When it is necessary to use the electronic atomization device 300 for suction, the power switch of the power supply assembly 200 can be turned on first, so that the power supply assembly 200 supplies power to the atomizer 100; then, when the user inhales the mouthpiece where the air inlet 94 of the atomizer 100 is located, the controller 220 of the electronic atomization device 300 can start the atomizer 100 to work according to the inhalation action, and finally generate the aerosol for the user to inhale. Among them, the liquid from the liquid receiving space 91 is heated and atomized by the heating element 20 to form an aerosol, and the external air can flow through the air inlet pipe 52, the second receiving space 51 and the air inlet groove 47 in sequence, and is delivered to the upper part of the atomization surface 11 of the liquid guiding element 10 in the first bracket 40 through the air inlet 471, and then carry the formed aerosol out of the smoke output channel 92.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
