Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning articles by creating products that release compounds without combustion.

[0003] An example of such a product is a heating device that releases compounds by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol providing products, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or a fragrance and / or an aerosol-generating substance (e.g., glycerol). Known electronic atomization devices generate aerosols by absorbing liquid through a sheet-like porous body and heating the liquid matrix in the porous body by a heating element attached to the surface of the porous body. Chinese patent CN221128829U proposes arranging the sheet-like porous body obliquely so that the airflow is smoother when flowing through the heating element; and a conductive electrical contact is longitudinally pressed against the heating element on the inclined surface of the porous body to guide current on the heating element. During assembly, the rigid contact of the electrical contacts against the heating element can easily lead to damage or breakage of the porous body. Therefore, alleviating the damage of the electrical contacts to the porous body and improving the reliability of the conductive contact between the two during the assembly process are issues that need to be paid attention to and resolved.

Based on typical usage requirements, the proximal end 110 is configured as the end through which the user inhales the aerosol. An air outlet 113 is provided at the proximal end 110 for the user to inhale. The distal end 120 of the housing 10 is open, sealed by an end cap 20. This open structure is used to install various functional components within the housing 10.

Furthermore, the first housing portion 11 is exposed outside the receiving cavity 2170, and the step defined between the first housing portion 11 and the second housing portion 12 abuts against the end of the power supply mechanism 200, thereby securing the atomizer 100 when received in the receiving cavity 2170.

The space between the outer surface of the aerosol output tube 111 and the inner surface of the housing 10 forms a liquid storage chamber 112 for storing a liquid matrix. The end of the aerosol output tube 111 close to the proximal end 110 is connected to the air outlet 113, thereby transmitting the generated aerosol to the air outlet 113 for inhalation by the user. Figure 5 and Figure 6 As shown in FIG, the aerosol output tube 111 and the housing 10 are integrally molded using a moldable material, and the liquid storage chamber 112 formed therefrom is closed on the proximal end 110 side and open on the distal end 120 side.

Specifically, the atomizing assembly 30 includes a porous body 31 and a heating element 32 at least partially surrounding the porous body 31.

[0100] In some embodiments, the porous body 31 is generally configured to be in a sheet-like shape. In some embodiments, the porous body 31 has a first side 311 and a second side 312 opposite to each other. The first side 311 is in fluid communication with the liquid storage chamber 112; for example, Figure 5 and Figure 6 The first side 311 shown by the middle arrow R1 is fluidically connected to the liquid storage chamber 112 through the liquid channel 41 defined in the bracket 40 to receive the liquid matrix; the surface of the second side 312 of the porous body 31 is configured as an atomizing surface, and the heating element 32 is combined with the atomizing surface / the surface of the second side 312 of the porous body 31.

Figure 5 and Figure 6 As shown by the arrow R2.

[0103] In accordance with Figures 2 to 6 、 Figure 19 and Figure 20In the illustration, the porous body 31 is square in shape; alternatively, in some alternative embodiments, the porous body 31 may be substantially circular, oval, polygonal, or other shapes with side notches.

[0107] In some embodiments, the plurality of liquid conducting holes 312 in the porous body 31 extend straight along the thickness direction of the porous body 31; alternatively, the liquid conducting holes 313 penetrate the porous body 31 along the thickness direction of the porous body 31. Furthermore, in some embodiments, the plurality of liquid conducting holes 313 are arranged in an orderly manner within the porous body 31. The plurality of liquid conducting holes 313 extend in a predetermined direction, rather than in a disordered manner. Furthermore, in some embodiments, the plurality of liquid conducting holes 313 are arranged in an array within the porous body 31; furthermore, in some embodiments, the plurality of liquid conducting holes 313 can transfer a liquid matrix from the first side 311 to the second side 312 at a predetermined rate. In some embodiments, the arrangement of the plurality of liquid conducting holes 313 within the porous body 31 gives the porous body 31 a honeycomb structure.

[0114] In some embodiments, the diameter of the liquid-conducting hole 313 in the porous body 31 ranges from 10 to 120 μm. The diameter of the liquid-conducting hole 313 can represent the distance between the radial center and two points on the edge of the substantially circular liquid-conducting hole 313. For liquid-conducting holes 313 that are not perfectly circular, the diameter of the liquid-conducting hole 313 can be represented by the maximum radial width of the liquid-conducting hole 313. More preferably, the diameter of the liquid-conducting hole 313 ranges from 40 to 100 μm.

[0115] Or in some other variations, the liquid guide hole 313 can be a triangle, a quadrilateral, a pentagon or other more shapes; then the diameter of such a non-circular liquid guide hole 313 can be represented as twice the distance from the geometric center of the liquid guide hole 313 to one of its vertices.

[0116] In some embodiments, the shortest distance between adjacent liquid-conducting holes 313 in the porous body 31 is between 5 μm and 35 μm. Figure 19 and Figure 20As shown in , the shortest distance between adjacent liquid guiding holes 313 can be understood as the distance between them along a virtual straight line passing through the centers of the two adjacent liquid guiding holes 313. For non-circular liquid guiding holes 313 such as triangles, quadrilaterals, and pentagons, the shortest distance between two adjacent liquid guiding holes 313 can be understood as the spacing distance along a virtual straight line passing through the geometric centers of the two adjacent liquid guiding holes 313.

[0144] In the adapted structure, a positioning groove 431 is arranged on the bracket 40; the positioning groove 431 is a concave structure located on the bracket 40. For example, Figure 7 During assembly of the bracket 40 and the first sealing element 50, as indicated by arrow P12, the positioning protrusion 514 of the end wall 510 extends or is inserted into the positioning groove 431, thereby providing positioning for the first sealing element 50 and the bracket 40 during assembly.

[0149] After assembly, the first sealing rib 521 and / or the second sealing rib 522 are at least partially squeezed or compressed by the bracket 40 and the housing 10 .

[0150] according to Figures 3 to 14 As shown, the bracket 40 is arranged with:

[0151] The retaining wall 48 is arranged at an angle to retain or support the atomizing assembly 30. After assembly, the atomizing assembly 30 is also arranged at an angle. The retaining wall 48 has a relief hole 481. After assembly, at least a portion of the surface of the first side 311 of the porous body 31 is facing or exposed to the relief hole 481.

[0152] according to Figures 3 to 14 As shown, the liquid channel 41 of the bracket 40 extends from the first end 410 to the avoidance hole 481 of the retaining wall 48. The liquid channel 41 is arranged substantially longitudinally. A plurality of longitudinally extending ridges 411 are arranged on the inner surface of the liquid channel 41. The ridges 411 are used to guide the liquid channel 41 to flow toward the avoidance hole 481.

[0153] according to Figures 3 to 14 As shown, the bracket 40 is provided with:

[0154] An insertion opening 42 is disposed at the first end 410 of the bracket 40. The insertion opening 42 is used to insert the aerosol delivery tube 111 to establish a connection.

[0155] according to Figures 3 to 14 As shown, the bracket 40 is provided with:

[0156] The positioning groove 431 is adapted to fit with the positioning protrusion 514 of the first sealing element 50. The positioning groove 431 is arranged around the fence 43; or, the positioning groove 431 is defined between the fence 43 and the outer surface of the bracket 40. Figures 3 to 14 As shown, a retaining edge 432 is provided between the positioning groove 431 and the liquid channel 41 , and a notch 433 is arranged on the retaining edge 432 ; when the first sealing element 50 is coupled to the bracket 40 , the liquid guiding groove 513 is communicated with the liquid channel 41 via the notch 433 .

When the aerosol delivery tube 111 is inserted into the insertion port 42, a capillary gap is formed between the aerosol delivery tube 111 and the drainage protrusion 436. The capillary gap can be, for example, 0.1 to 1 mm. The capillary gap generates a capillary attraction force that guides aerosol condensate falling from the inner surface of the aerosol delivery tube 111 toward the partition wall 434, thereby preventing aerosol condensate from flowing with the airflow toward the air outlet 113 during inhalation. Alternatively, in some alternative embodiments, when the aerosol delivery tube 111 is inserted into the insertion port 42, the aerosol delivery tube 111 longitudinally abuts against the drainage protrusion 436.

[0159] In the embodiment, the retaining wall 48 is located between the partition wall 434 and the second end 420. The retaining wall 48 extends from the partition wall 434 away from the first end 410. The retaining wall 48 and the partition wall 434 form an angle therebetween; more preferably, the angle therebetween is an obtuse angle.

[0160] according to Figures 3 to 14 As shown, the bracket 40 is also arranged with:

[0161] The condensate collection chamber 437 is used to collect or retain aerosol condensate directed onto the partition wall 434 via the drainage protrusion 436. A communication opening 425 is provided on the inner surface of the insertion port 42, through which the condensate collection chamber 437 communicates with the insertion port 42. In an embodiment, the condensate collection chamber 437 extends radially along the support 40; specifically, the condensate collection chamber 437 extends radially outward from the inner surface of the insertion port 42. The condensate collection chamber 437 extends from the inner surface of the insertion port 42 to the outer surface of the support 40.

In an embodiment, there are two positioning grooves 431. The condensate collection chamber 437 is located between the two positioning grooves 431.

[0162] according to Figures 3 to 14 As shown, the condensate collecting chamber 437 is closer to the first end 410 and / or the proximal end 110 than the cavity 49 to prevent condensate from leaking from the air outlet 113 when the nebulizer 100 is in an inverted state during transportation or environmental testing. Figures 3 to 14 As shown, in the longitudinal direction of the atomizer 100 , the communication port 425 and / or the condensate collection chamber 437 are staggered with respect to the aerosol output tube 111 ; after assembly, the communication port 425 is not blocked or covered by the aerosol output tube 111 .

[0164] according to Figures 3 to 14 As shown, the bracket 40 is also arranged with:

[0165] Cavity 49 is at least partially defined by retaining wall 48 and partition wall 434. Cavity 49 is located on one side of retaining wall 48, and liquid passage 41 is located on the other side of retaining wall 48. Atomizer assembly 30 is accommodated in cavity 49 and rests against retaining wall 48 and / or partition wall 434. In an embodiment, cavity 49 is at least partially located between insertion port 42 and second end 420.

[0166] In an embodiment, the cavity 49 is configured to provide an assembly passage for assembling or coupling the atomizer assembly 30 to the retaining wall 48 and / or the dividing wall 434. Specifically, the cavity 49 is formed or defined with a side opening 491 on the outer surface of the bracket 40. The side opening 491 is radially opposite the retaining wall 48. During assembly, the atomizer assembly 30 is assembled into the cavity 49 of the bracket 40 through the side opening 491 and abuts against the retaining wall 48 and / or the dividing wall 434.

[0167] In this embodiment, after assembly, the second side 312 of the porous body 31 of the atomizer assembly 30 faces or is exposed to the cavity 49. At least a portion of the cavity 49 forms or defines an atomization chamber 340 for releasing the aerosol generated by the atomizer assembly 30. Accordingly, the partition wall 434 is provided with airflow holes 435 for discharging the aerosol from the cavity 49 and / or the atomization chamber 340 to the aerosol output tube 111. After assembly, the airflow holes 435 are longitudinally aligned with the aerosol output tube 111.

[0168] according to Figures 3 to 14 As shown, the atomizer 100 further includes:

[0169] The blocking element 70 is made of flexible silicone or thermoplastic elastomer. The blocking element 70 is used to close or block the side opening 491 of the cavity 49. In one aspect, the side opening 491 of the cavity 49 is closed by the blocking element 70, thereby preventing the aerosol from being released or escaping from the side opening 491. In another aspect, the blocking element 70 extends into the cavity 49 from the side opening 491, and the atomization chamber 340 is formed or defined between the blocking element 70 and the second side 312 of the porous body 31; the blocking element 70 can limit or define the spatial volume of the atomization chamber 340, which is beneficial for maintaining the aerosol heated and released into the atomization chamber 340 at a suitable concentration. Specifically, a groove 71 is arranged on the surface of the blocking element 70 facing the porous body 31. The groove 71 is arranged to extend in the longitudinal direction; or, the groove 71 extends through the blocking element 70 in the longitudinal direction. The groove 71 is opposite to the second side 312 of the porous body 31 , and at least partially defines the atomization chamber 340 .

[0170] After assembly, the obstructing element 70 is spaced from the second side 312 of the porous body 31 .

[0171] according to Figure 13 and Figure 14 As shown, the outer surface of the blocking element 70 is provided with a plurality of capillary grooves for adsorbing or transferring aerosol condensate within the atomization chamber 340. For example, a first capillary groove 72 is provided on the outer surface of the blocking element 70 facing away from the porous body 31; a second capillary groove 73 is provided on the upper surface of the blocking element 70 facing the first end 410; and a third capillary groove 74 is provided on both sides of the width of the blocking element 70.

The second adsorption grooves 46 extend to or communicate with the side opening 491 . After assembly, the second adsorption grooves 46 communicate with the capillary grooves of the blocking element 70 ; alternatively, the second adsorption grooves 46 communicate with the atomization chamber 340 via the capillary grooves on the surface of the blocking element 70 , thereby adsorbing and retaining aerosol condensate through capillary action. The second adsorption grooves 46 are isolated from the first adsorption groove 438 .

[0173] according to Figures 3 to 14 As shown, the bracket 40 is also arranged with:

[0174] The ventilation channel 44 is formed on the outer surface of the bracket 40. The ventilation channel 44 is used to form or provide an air passage connecting the liquid storage chamber 112 and the atomization chamber 340, thereby balancing the pressure in the liquid storage chamber 112. Alternatively, the ventilation channel 44 is used to provide a passage path for air to enter the liquid storage chamber 112.

[0175] according to Figures 3 to 14 As shown, the ventilation channel 44 is configured as a ventilation groove or recess formed on the outer surface of the bracket 40. The ventilation channel 44 extends substantially longitudinally. In an embodiment, at least a portion of the ventilation channel 44 is configured as a Tesla valve structure; the Tesla valve structure has multiple branches that diverge and converge. With the Tesla valve structure, the resistance to air passing through the ventilation channel 44 into the liquid reservoir 112 is less than the resistance to the liquid medium within the liquid reservoir 112 flowing out through the ventilation channel 44. This is advantageous for preventing or reducing the outflow of the liquid medium within the liquid reservoir 112.

[0176] For example, according to Figure 10 As shown by the middle arrow R3 , when the negative pressure in the liquid storage chamber 112 reaches or exceeds the threshold, the air in the cavity 49 can enter the liquid storage chamber 112 through the ventilation channel 44 to relieve or eliminate the negative pressure in the liquid storage chamber 112 .

[0177] according to Figure 10 As shown in FIG, the ventilation channel 44 is formed or defined with a communication gap 441 at the first end 441 of the bracket 40. The communication gap 441 is used to connect the ventilation channel 44 to the liquid channel 41, and then to communicate with the liquid storage chamber 112.

[0178] according to Figure 10 As shown in , the outer surface of the bracket 40 is also arranged with:

[0179] At least one ventilation compartment, such as the first ventilation compartment 45 and the second ventilation compartment 47. The at least one ventilation compartment is in communication with the liquid storage chamber 112 through the ventilation channel 44.

[0180] During use, for example, during high-altitude flight transportation or product environmental testing, when the pressure in the liquid storage chamber 112 is greater than the external pressure, the liquid matrix in the liquid storage chamber 112 and / or the liquid channel 41 flows to the at least one ventilation compartment for storage via the ventilation channel 44. When the pressure in the liquid storage chamber 112 is less than the external pressure, the liquid matrix that has seeped into the at least one ventilation compartment can flow back to the liquid channel 41 and / or the liquid storage chamber 112 via the ventilation channel 44. Furthermore, the at least one ventilation compartment is further configured to provide air communication between the cavity 49 and the ventilation channel 44.

[0181] according to Figure 10 As shown in , at least one ventilation compartment comprises:

[0182] The first ventilation compartment 45 and the second ventilation compartment 47 are arranged sequentially along the circumference of the bracket 40. The first ventilation compartment 45 and the second ventilation compartment 47 are separated by a retaining edge 452. Furthermore, a notch 453 is provided on the retaining edge 452 to allow air to flow between the first ventilation compartment 45 and the second ventilation compartment 47.

[0183] according to Figure 10 As shown in FIG, there are two first ventilation compartments 45 and one second ventilation compartment 47. The two first ventilation compartments 45 are located on both sides of the second ventilation compartment 47 respectively.

[0184] according to Figure 10 As shown in FIG, the ventilation channel 44 is substantially longitudinally extending. The ventilation channel 44 extends from the second ventilation compartment 47 to the first end 410. The ventilation channel 44 is connected to the second ventilation compartment 47. The first ventilation compartment 45 is substantially staggered with the ventilation channel 44 in the longitudinal direction.

[0185] according to Figure 10 As shown in FIG, the first ventilation compartment 45 is connected to the cavity 49 via the air hole 451. Alternatively, the air hole 451 extends from the first ventilation compartment 45 to the cavity 49. During use, when the pressure in the liquid storage chamber 112 is lower than the external pressure, the air in the cavity 49 enters the first ventilation compartment 45 through the air hole 451, and then passes through the second ventilation compartment 47 and the ventilation channel 44 before entering the liquid storage chamber 112.

[0186] according to Figure 10 As shown in FIG, a plurality of ridges 471 are arranged in the second ventilation compartment 47; the ridges 471 are arranged to extend longitudinally, and adsorption grooves 471 are defined between adjacent ridges 471 for adsorbing or retaining the liquid matrix flowing from the ventilation channel 44 into the second ventilation compartment 47.

[0187] according to Figure 10 As shown in FIG, the second adsorption groove 46 extends from the first ventilation compartment 45 to the side opening 491. The second adsorption groove 46 is in communication with the first ventilation compartment 45.

[0188] according to Figures 3 to 13 As shown, the bracket 40 is also provided with:

[0189] The air inlet channel 423 is used to connect the air inlet 21 with the cavity 49 and / or the atomization chamber 340 , thereby supplying air from the air inlet 21 to enter the cavity 49 and / or the atomization chamber 340 .

[0190] according to Figure 11As shown, at least a portion of the cross-sectional area of ​​the air inlet passage 423 varies. The air inlet passage 423 is tapered. At least a portion of the inner surface of the air inlet passage 423 is arranged at an angle. Specifically, at least a portion of the cross-sectional area of ​​the air inlet passage 423 decreases as it approaches the cavity 49 and / or the atomizing chamber 340. The port of the air inlet passage 423 facing the cavity 49 and / or the atomizing chamber 340 is staggered or offset from the porous body 31 and / or the atomizing assembly 30. Specifically, after assembly, the port of the air inlet passage 423 facing the cavity 49 and / or the atomizing chamber 340 is opposite to the blocking element 70.

[0191] according to Figures 3 to 13 As shown, the bracket 40 is also provided with:

[0192] The accommodating chamber 422 is located at the second end 420 . The air inlet passage 423 passes through the accommodating chamber 422 to the cavity 49 and / or the atomizing chamber 340 .

[0193] according to Figures 3 to 13 As shown, the atomizer 100 further includes:

[0194] At least one absorption element 23 is housed or assembled within the accommodating cavity 422. The at least one absorption element 23 is porous. The at least one absorption element 23 is made of a porous material, such as a porous capillary material. For example, the at least one absorption element 23 can be made of cotton fiber, sponge, non-woven fabric, etc. The at least one absorption element 23 is configured to absorb aerosol condensate flowing out of the air inlet passage 423, thereby preventing the aerosol condensate from flowing out to the air inlet 21 of the end cap 20.

[0195] In an embodiment, an airflow channel within the atomizer 100 is formed or defined between the air inlet 21 and the air outlet 113 to provide an airflow path for air from the air inlet 21 through the atomization assembly 30 and / or the atomization chamber 340 to the air outlet 113, thereby delivering the aerosol to the air outlet 113. The complete airflow channel is defined by multiple components. Furthermore, the airflow channel passes through at least one absorption element 23. Furthermore, the airflow channel passes through the bracket 40.

[0196] Specifically based on Figure 5 As shown by the middle arrow R2, air enters from the air inlet 21 of the end cover 20, then passes through at least one absorption element 23 and enters the cavity 49 and / or the atomization chamber 340 via the air inlet channel 423, and then carries the aerosol in the atomization chamber 340 through the air flow through-hole 435 and the aerosol output tube 111 to be output to the air outlet 113.

[0197] In an embodiment, at least a portion of the airflow path passes through the bracket 40 .

[0198] according to Figures 15 to 18As shown, the electrical contact 22 extends from the second end 420 of the bracket 40 into the cavity 49. The electrical contact 22 abuts against the surface of the second side 312 of the porous body 31, providing a supporting force F to the porous body 31 at least partially from the second side 312. After assembly, the porous body 31 and / or the atomization assembly 30 are at least partially supported by the electrical contact 22. In this embodiment, the electrical contact 22 abuts against the electrode portions of the heating element 32, namely the first electrode portion 321 and the second electrode portion 322.

[0199] according to Figures 15 to 18 As shown, the electrical contact 22 is longitudinally extended and has an abutting portion 221 ; after assembly, the electrical contact 22 abuts against the heating element 32 and / or the porous body 31 via the abutting portion 221 .

[0200] according to Figures 15 to 18 As shown, the electrical contact 22 has a front end and a rear end facing each other. The abutting portion 221 is located at the front end.

[0201] according to Figures 15 to 18 As shown, the outer surface of the abutment portion 221 is a curved surface. Figures 15 to 18 In the embodiment, the abutment portion 221 is conical in shape, and the outer surface of the abutment portion 221 is a conical curved surface. The length of the abutment portion 221 is approximately 1 to 4 mm. The diameter of the abutment portion 221 gradually decreases; specifically, the diameter of the abutment portion 221 decreases as it approaches the front end. The outer surface of the abutment portion 221 is inclined. Specifically, the angle α between the outer surface of the abutment portion 221 and the axial direction is approximately 5° to 45°; the angle α is the angle between the outer surface of the abutment portion 221 and its central axis. In an embodiment, the angle α between the outer surface of the electrical contact 22 extending longitudinally along the atomizer 100 and the axial direction is also the angle between the outer surface of the abutment portion 221 and the longitudinal direction of the atomizer 100. Alternatively, in more alternative embodiments, the abutment portion 221 has a pyramidal shape such as a triangular pyramid or a quadrangular pyramid.

[0202] Or in more variations, the outer surface of the abutting portion 221 is a curved arc surface, a spherical surface, etc.

[0203] according to Figures 15 to 18 As shown, the tilted atomizing assembly 30 and / or the porous body 31 have an inclination angle β with the longitudinal direction of the atomizer 100. Alternatively, the atomizing surface of the porous body 31 and / or the surface of the second side 312 are tilted; and the atomizing surface of the porous body 31 and / or the surface of the second side 312 have an inclination angle β with the longitudinal direction of the atomizer 100. In an embodiment, the angle of the inclination β is the same as the angle α. Correspondingly, the angle of the inclination α of the outer surface of the abutment portion 221 is the same as the angle of the inclination angle β of the atomizing assembly 30 and / or the porous body 31. Figure 17 As shown by the middle arrow P11 , when the electrical contact 22 is assembled into the bracket 40 , it is advantageous for the abutting portion 221 and the atomizing assembly 30 to have the same inclination angle to form good contact and abutment.

[0204] In some preferred embodiments, the inclination angle α of the outer surface of the abutting portion 221 is approximately 15° to 25°; or in a specific embodiment, the inclination angle α of the outer surface of the abutting portion 221 is approximately 20°.

[0206] After assembly, the abutment portion 221 and the porous body 31, each having an outer surface with the same inclination angle, are in line contact, not point or surface contact. The electrical contact 22 is in rigid contact with the porous body 31 and / or the atomizing assembly 30; the electrical contact 22 is in non-elastic contact with the porous body 31 and / or the atomizing assembly 30.

[0207] according to Figures 15 to 18 As shown, the electrical contact 22 is made of a low-resistance metal or alloy, such as gold, silver, copper, or other electrode materials. The electrical contact 22 is rigid and non-elastic. Therefore, the electrical contact 22 and the heating element 32 are in rigid, non-elastic contact.

[0208] Or in some other variations of the embodiments, the abutment 221 of the electrical contact 22 has an inclined flat surface; after assembly, the inclined flat surface of the abutment 221 abuts against the surface of the second side 312 and / or the atomizing surface of the porous body 31. In an embodiment, the inclined flat surface of the abutment 221 is arranged obliquely. In an embodiment, the inclined flat surface of the abutment 221 is parallel to the surface of the second side 312 and / or the atomizing surface of the porous body 31. After assembly, the abutment 221 of the electrical contact 22 is in planar contact with the porous body 31. In an embodiment, an angle α is formed between the flat surface of the abutment 221 and the longitudinal direction of the atomizer 100; and the angle α is the same as the angle of the inclination angle β.

[0209] according to Figures 15 to 18 As shown, the electrical contact 22 further has a base 222 at the end. After assembly, the base 222 is firmly coupled to the bracket 40. When the atomizer 100 is received in the power supply mechanism 200, the base 222 contacts and abuts against the electrical contact 2130 of the power supply mechanism 200 to establish a conductive connection. Figures 15 to 18As shown, the base 222 is arranged in a sheet or plate shape perpendicular to the longitudinal direction.

[0210] according to Figures 3 to 18 As shown, the atomizer 100 further includes:

[0211] The second sealing element 60 is made of flexible silicone, thermoplastic elastomer, etc. The second sealing element 60 is arranged between the atomizing assembly 30 and the bracket 40 to provide a seal therebetween.

[0212] Specifically in the embodiment, the second sealing element 60 abuts against the retaining wall 48 and the partition wall 434 .

[0213] In an embodiment, the second sealing element 60 is substantially annular in shape. The second sealing element 60 has a central hole 61; the atomizing assembly 30 and / or the porous body 31 are at least partially located within the central hole 61. The second sealing element 60 also has an abutment step 62 located within the central hole 61, and the atomizing assembly 30 and / or the porous body 31 abut against the abutment step 62.

[0214] In an embodiment, the second sealing element 60 at least partially surrounds or encloses the atomizing assembly 30 / the porous body 31. In an embodiment, the second sealing element 60 is coupled to the dense portion 315 of the porous body 31 and avoids the porous liquid-conducting portion 314.

[0215] according to Figures 3 to 18 As shown, after assembly, the flexible second sealing element 60 can also be used to provide elastic or resilient support to the first side 310 of the atomizing assembly 30 / porous body 31; the direction of the elastic force is the same as Figure 18 The direction of the supporting force F of the middle electrical contact 22 is opposite. The elastic force of the second sealing element 60 causes the porous body 31 / heating element 32 to abut against the abutting portion 221 of the electrical contact 22 stably, which is beneficial for improving the contact stability between the heating element 32 and the electrical contact 22.

[0216] according to Figures 3 to 18 As shown, a groove 482 is arranged on the surface of the retaining wall 48 ; when the second sealing element 60 abuts against or is coupled to the retaining wall 48 , a gap is formed between the second sealing element 60 and the retaining wall 48 due to the groove 482 .
