As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the technical features mentioned in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

Fig. 1 to fig. 3 are a schematic perspective view and a schematic cross-sectional view of an electronic atomizer 100 according to an embodiment of the present invention. The electronic atomizing device 100 may generally include a solid substrate heating assembly 10, an atomizing assembly 20, a housing assembly 30, and a power supply assembly 40. The housing assembly 30 houses the solid substrate heating assembly 10, the atomizing assembly 20, and the power supply assembly 40, the power supply assembly 40 including portions for providing electrical power required for operation of the solid substrate heating assembly 10 and the atomizing assembly 20, and further including portions that can control operation of the solid substrate heating assembly 10 and the atomizing assembly 20.

As shown in fig. 3 and fig. 5, the electronic atomization device 100 includes a containing chamber 111, where the containing chamber 111 is used for containing a solid first substrate 201. The cartridge 111 may be defined by a housing member of the electronic atomizer device 100. The solid substrate heating assembly 10 is used to heat a solid first substrate 201 and generate a first aerosol. The first substrate 201 may also be referred to as an aerosol-generating article, which may be in the form of a cigarette, for example, having an internal airflow path; the holding chamber 111 may also be referred to as a heating chamber. The atomizing assembly 20 is used for atomizing a liquid second substrate 202, such as tobacco tar, liquid medicine, etc., and generating a second aerosol, and the second substrate 202 may also be a solid substrate as long as the aerosol is generated when heated. Wherein the solid substrate heating assembly 10 may be positioned above the atomizing assembly 20. The atomizing assembly 20 has a first air outlet 213 a. A second channel 152 may be disposed between the first air outlet 213a and the accommodating chamber 111, and the second channel 152 has a first air inlet 152a and a second air outlet 152 b; the first air outlet 213a is directly or indirectly communicated with the first air inlet 152a, the second air outlet 152b is communicated with the accommodating chamber 111, and the second aerosol enters the accommodating chamber 111 through the second passage 152. The cross-sectional area of the second channel 152 varies uniformly, e.g., may gradually decrease or gradually increase, in a direction away from the atomizing assembly 20. In addition, the cross-sectional area of the second channel 152 may gradually decrease and then gradually increase, or gradually increase and then gradually decrease, etc. in a direction away from the atomizing assembly 20. It is noted that a gradual transition as referred to herein means that the surface changes in a gentle manner, so that the surface as a whole is relatively smooth, with no or few kinked portions; additionally, the tapered surface may comprise one or more cylindrical surfaces. As shown, whether the cross-sectional area of the second channel 152 increases or decreases in a direction away from the atomizing assembly 20, the cross-sectional dimension of the second channel 152 is at least greater than the opening dimension of the first air outlet 213a, which makes the second channel 152 larger in size and less prone to block the transport of aerosol.

It is noted that when the first substrate 201 and the second substrate 202 are atomized to form a product having a respiratory tract therapeutic effect, the electronic atomization device 100 can be referred to as a respiratory tract electronic atomizer; when the first substrate 201 and the second substrate 202 are atomized to form a product similar to cigarette smoke, the electronic atomization device 100 can be called an electronic smoking set.

In the electronic atomizing device 100 of this embodiment, the outlet of the second aerosol generated by the atomizing assembly 20 is the first air outlet 213a, the second channel 152 is disposed between the accommodating chamber 111 accommodating the first substrate 201 and the first air outlet 213a, and the cross-sectional area of the second channel 152 is designed to be uniformly changed in a direction away from the atomizing assembly 20, so as to provide a smooth transmission channel, and further, the second aerosol can be smoothly transmitted to the accommodating chamber through the second channel 152, thereby reducing the generation of condensate.

In some embodiments, as shown in fig. 3, the center of the orthographic projection of the second air outlet 152b on the first plane is offset from the center of the orthographic projection of the first air outlet 213a on the first plane, wherein the first plane is a plane perpendicular to the up-down direction a 1. For example, the central axis of the second air outlet 152b is not aligned with the central axis of the first air outlet 213 a. In some embodiments, an orthographic projection of the second air outlet 152b on a plane perpendicular to the up-down direction a1 does not overlap with an orthographic projection of the first air outlet 213a on the plane. Therefore, by arranging the first air outlet 213a eccentrically with respect to the second air outlet 152b, the impurities such as smoke oil condensate and smoke residue generated by the solid matrix heating assembly 10 in the accommodating chamber 111 are prevented from directly dropping into the airflow channel of the atomizing assembly 20, and the atomizing effect of the liquid atomizing assembly is prevented from being affected, so as to provide better overall suction experience.

In some embodiments, as shown in connection with fig. 3, the atomizing assembly 20 and the holding chamber 111 can also be in fluid communication such that a second aerosol can enter the holding chamber 111; accordingly, when a first substrate 201, such as a cigarette, is placed in the holding chamber 111, a second aerosol can enter the interior of the first substrate 201 as drawn by the user. Furthermore, when, for example, the first substrate 201 of the cigarette and the outer peripheral side of the cartridge 111 have a gap or flow channel, the second aerosol can also enter such a gap or flow channel.

In some embodiments, the solid substrate heating assembly 10 may be a center heating type structure, for example, it may include a heat generating body for inserting inside the first substrate 201 and for generating heat for heating the first substrate 201, and further may be radiatively heated by means of infrared rays. At this time, a space defined in the electronic atomization device 100 for receiving the first substrate 201 may be defined as a receiving chamber. The heating body can be in the form of a heating sheet or a heating needle.

In some embodiments, as shown in connection with fig. 3, 5, 14-16, the solid substrate heating assembly 10 is in the form of circumferential heating. For example, the solid substrate heating assembly 10 may include a tubular heating element 10a, the tubular heating element 10a may include a heating base 11 and a lower end cap 151, the heating base 11 may be hollow, and the inside thereof forms the housing chamber 111. The lower end cap 151 defines at least part of the second channel 152. The lower end of the heating base 11 is connected to the lower end cap 151, and the lower end cap 151 and the heating base 11 are in fluid communication. The tubular heating element 10a can bake heat the first substrate 201 by electromagnetic heating, resistance heating, infrared heating, or the like.

In a further embodiment, as shown in fig. 3 and 5, a first orthographic projection of the inner side surface of the second channel 152 on a first plane, which is a plane perpendicular to the up-down direction, and a second orthographic projection of the first air outlet 213a on the first plane may overlap by at least 50%. The overlap may be, for example, 60%, 70%, 80%, 90%, 100%, etc. It will be readily appreciated that the higher the degree of overlap, i.e., the more interior sides of the second channels 152 cover the first air outlet openings 213a, the better the prevention of impurities from falling directly into the first air flow channels 213 of the atomizing assembly 20.

In other embodiments, the second air outlet 152b and the first air outlet 213a may be disposed in a state of no or little front-to-front opposition in the up-down direction a1, which may also better prevent impurities from directly falling into the first air flow channel 213 of the atomizing assembly 20. For example, the first air outlet 213a may be located below the second air outlet 152b, but the first air outlet 213a is disposed to face the left or right side, rather than facing the second air outlet 152b upward. Alternatively, the first air outlet 213a may be opened outside the second channel 152 and then communicated with the inner side surface of the second channel 152.

In a further embodiment, as shown in fig. 3 and 5, the cross-sectional area of the second channel 152 gradually decreases in a direction away from the atomizing assembly 20, and the first air outlet 213a is disposed near the side of the first air inlet 152 a.

In a further embodiment, as shown in conjunction with fig. 3, 5 and 21, the lower end cap 151 further defines a mounting groove 153, the mounting groove 153 is provided with the airflow sensor 44 therein, and the airflow sensor 44 is in airflow communication with the second channel 152 through a communication groove 154. A sealing member may be further disposed between the lower cover 151 and the air flow sensor 44 to prevent air leakage through the mounting groove 153. The airflow sensor 44 may be a microphone. In addition, the communication groove 154 may be disposed adjacent to the first air outlet 213a, so that the air flow sensor 44 may rapidly sense a change in air flow pressure near the first air outlet 213 a.

In some embodiments, as shown in conjunction with fig. 14-16, the tubular heating element 10a is configured to bake heat the first substrate 201 in an infrared heating manner. The solid substrate heating assembly 10 may further include an infrared electrocaloric coating 12, a first electrode 13, and a second electrode 13 a. The infrared electrothermal coating 12 is coated on the outer side of the heating substrate 11. The first electrode 13 is arranged on the outer side of the heating substrate 11 and is in contact with the infrared electrothermal coating 12, the second electrode 13a is arranged on the outer side of the heating substrate 11 and is in contact with the infrared electrothermal coating 12, and at least one part of the infrared electrothermal coating 12 is positioned between the first electrode 13 and the second electrode 13 a. The first electrode 13 and the second electrode 13a are electrically connected to the power supply assembly 40, so that at least a portion of the infrared electrothermal coating 12 receives heat generated by electric power, thereby generating infrared rays for radiatively heating the solid first substrate 201.

In the electronic atomization device 100 of the above embodiment, since the infrared light generated by the solid substrate heating element 10 has strong penetrability, the infrared light can penetrate through the surrounding first substrate 201 into the inside, so that the first substrate 201 can be heated more uniformly. Furthermore, it is easy to understand that since the second aerosol also has a higher temperature, the second aerosol can also heat and bake the first substrate 201 when passing through the inside of the first substrate 201.

In some embodiments, the infrared electrothermal coating 12 is used for receiving electric power to generate heat, and then generating infrared rays with certain wavelength, such as far infrared rays with a wavelength of 8 μm to 15 μm. When the wavelength of the infrared ray matches the absorption wavelength of the first substrate 201, the energy of the infrared ray is easily absorbed by the first substrate 201. In this example, the wavelength of the infrared ray is not limited, and may be an infrared ray of 0.75 to 1000 μm, and further may be a far infrared ray of 1.5 to 400 μm.

The infrared electric heating coating 12 can be formed by fully and uniformly stirring far infrared electric heating ink, ceramic powder and an inorganic adhesive, then coating, drying and curing for a certain time, and the thickness of the infrared electric heating coating can be 30-50 mu m; certainly, the infrared electric heating coating can also be formed by mixing and stirring tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride and anhydrous copper sulfate according to a certain proportion and then coating; or one of a silicon carbide ceramic layer, a carbon fiber composite layer, a zirconium-titanium oxide ceramic layer, a zirconium-titanium nitride ceramic layer, a zirconium-titanium boride ceramic layer, a zirconium-titanium carbide ceramic layer, an iron-based oxide ceramic layer, an iron-based nitride ceramic layer, an iron-based boride ceramic layer, an iron-based carbide ceramic layer, a rare earth oxide ceramic layer, a rare earth nitride ceramic layer, a rare earth boride ceramic layer, a rare earth carbide ceramic layer, a nickel-cobalt oxide ceramic layer, a nickel-cobalt nitride ceramic layer, a nickel-cobalt boride ceramic layer, a nickel-cobalt carbide ceramic layer or a high-silicon molecular sieve ceramic layer; the infrared electrothermal coating can also be other existing material coatings.

In other embodiments, the solid substrate heating assembly 10 may be a combination of central heating and circumferential heating. For example, the solid substrate heating assembly 10 may include the above-described heating element for insertion inside the first substrate 201, and the tubular heating element 10a for receiving the first substrate 201. Further, at least one of the central heating and the circumferential heating may be infrared heating.

In some embodiments, as shown in conjunction with fig. 3, 6, and 10-13, the atomizing assembly 20 is a liquid atomizing assembly for atomizing a liquid second substrate 202 and generating the second aerosol.

In some embodiments, as shown in conjunction with fig. 3, 6, and 10-13, the atomization assembly 20 includes a reservoir housing 21, a liquid directing element 22, and a heating element 23. The liquid storage case 21 defines a liquid receiving space 211 therein for receiving the liquid second substrate 202. The liquid guiding element 22 is in fluid communication with the liquid receiving space 211 for absorbing the second substrate 202 from the liquid receiving space 211. The heating element 23 is disposed adjacent to the wicking element 22 and is configured to heat at least a portion of the second substrate 202 absorbed by the wicking element 22 when energized to generate a second aerosol. It is noted that the proximity of heating element 23 to fluid-conducting element 22 may include both the case where heating element 23 is in direct contact with fluid-conducting element 22 and the case where heating element 23 is in indirect contact with fluid-conducting element 22; the fluid communication between the liquid guide member 22 and the liquid accommodation space 211 may be direct communication or indirect communication.

The wicking element 22 may be made of a material having capillary channels or pores, such as a hard or rigid capillary structure of cellucotton, a porous ceramic body, a glass fiber rope, a porous glass ceramic, a porous glass, or the like. The liquid guiding member 22 is in fluid communication with the liquid receiving space 211 to suck the liquid second substrate 202 delivered from the liquid receiving space 211 and to deliver the second substrate 202 to the vicinity of the heating member 23.

In a further embodiment, as shown in fig. 6 and 13, the liquid guiding member 22 includes an atomizing surface 221 and a liquid absorbing surface 222, and the liquid absorbing surface 222 is in fluid communication with the liquid accommodating space 211.

For example, the heating element 23 may be formed on the atomizing surface 221 of the liquid guiding element 22 by mounting, printing, depositing, or the like. The heating element 23 may be made of stainless steel, nichrome, ferrochromium alloy, titanium metal, etc. in some embodiments. As shown in fig. 13, the heating element 23 is a conductive track patterned in a meandering, circuitous, etc., and may include conductive terminals at both ends; the conductive terminals may be in the form of pads, which may have a square, circular, oval, etc. shape. The heating element 23 may also be a heating net, a heating sheet, or the like. The atomization surface 221 of the liquid guiding element 22 can be opposite to the liquid suction surface 222; alternatively, the side surface of the liquid guide member 22 may be a liquid suction surface.

In other embodiments, the liquid guiding element 22 may be an oil absorbent cotton, and the heating element 23 may be a heating wire, so that the heating wire can be energized to generate heat according to the heating principle of the resistance wire. The liquid accommodating space 211 is used for accommodating tobacco tar; the oil absorption cotton is used for absorbing the smoke oil in the liquid accommodating space 211 and providing the smoke oil for the heating wire; the heating wire is attached to the oil absorption cotton and used for heating the tobacco tar on the oil absorption cotton to generate corresponding tobacco tar smoke.

The above-described liquid guiding element 22 and heating element 23 may be implemented as two separate elements. However, in other embodiments, liquid conducting element 22 and heating element 23 may also be implemented as an integrated structure; for example, a heating net can be used for conducting and heating, that is, the heating net generates heat when being electrified, and filaments in the heating net form a capillary structure to conduct liquid; in addition, the ceramic heating element can be used for conducting liquid and heating, namely, the ceramic part of the ceramic heating element has a capillary action, so that liquid can be conducted, and the heating element is embedded in the ceramic part and can generate heat when electrified. In summary, wicking element 22 and heating element 23 of the present application may also be collectively referred to as a wicking heating element.

In still other embodiments, the atomizing assembly 20 may be used for ultrasonic atomization or molecular resonance atomization; this is not described in detail herein.

In some embodiments, as shown in conjunction with fig. 3, 6 and 10-13, the reservoir 21 further defines a first mounting space 212 and a first air flow channel 213, and the atomizing assembly 20 further includes a mounting assembly for mounting the aforementioned liquid-conducting heating element. For example, the mounting assembly may include a first mounting member 24.

The first mounting part 24 is disposed in the first mounting space 212, and the liquid guide member 22 is mounted on the first mounting part 24. The liquid receiving space 211 is in fluid communication with the liquid guiding member 22 through the liquid passage 241 of the first mounting part 24. The second aerosol generated by the atomizing assembly 20 is for delivery to the solid substrate heating assembly 10 via the first airflow channel 213. In addition, a second sealing member 26 may be disposed between the first mounting member 24 and the liquid storage case 21 to seal a gap therebetween. A third sealing member 26a may be disposed between the liquid guiding element 22 and the first mounting part 24, and the third sealing member 26a may be located between the liquid guiding element 22 and the bracket side wall of the first mounting part 24, for sealing and isolating the atomizing surface 221 from the liquid absorbing surface 222, that is, the liquid provided by the liquid accommodating space 211 can only enter the liquid guiding element 22 through the liquid absorbing surface 222 and then be delivered to the atomizing surface 221. The third seal 26a may be generally cup-shaped such that the fluid-conducting element 22 may be received within a recess of the cup-shaped third seal 26 a.

Further, the first air flow channel 213 may extend in the up-down direction a1 so as to be disposed in parallel with the housing bin 111 and directly communicate with the first air inlet 152a (see fig. 5) of the solid substrate heating assembly 10; in this way, the second aerosol can be smoothly output from the linear first airflow channel 213 and further conveyed toward the accommodating chamber 111; in addition, the straight first air flow channel 213 is also convenient for molding. In other embodiments, the first air flow channel 213 may not be limited to be parallel to the accommodating chamber 111, but may have various shapes such as bending, and the like.

Further, the first air flow channel 213 communicates with the accommodating chamber 111, and the first air flow channel 213 may be configured as the only air intake source of the accommodating chamber 111. Since the first air flow channel 213 is in direct and exclusive communication with the first air inlet 152a of the solid substrate heating assembly 10, the atomized second aerosol can enter the first substrate 201 as air for the solid substrate heating assembly 10, thereby allowing the first aerosol to be sufficiently expelled and producing a mixed-flavor smoke. For example, the first air flow channel 213 and the accommodating chamber 111 may be both vertically disposed, and the first air flow channel 213 is disposed eccentrically from the accommodating chamber 111.

In a further embodiment, as shown in fig. 6, 12 and 13, a check valve 246 is connected to the first mounting member 24, and the check valve 246 is used for introducing air into the liquid accommodating space 211. The check valve 246 is adapted to open under the influence of a pressure differential; accordingly, in the assembled electronic atomizing device 100, the check valve 246 allows air to be introduced into the liquid accommodating space 211, so that a large negative pressure caused by insufficient liquid in the liquid accommodating space 211 is prevented, and the liquid is smoothly discharged from the liquid accommodating space 211 to the liquid guide member 22. The check valve 246 may be, for example, a duckbill valve or the like that allows only air to enter the liquid housing space 211 from the outside.

In some embodiments, as shown in fig. 3, 5, 10 and 12, a smoke residue containing cavity 214 may be further provided on a side of the liquid storage shell 21 facing the containing bin 111. The slag receiving chamber 214 is disposed below, e.g., directly below or slightly offset from, the second outlet 152 b. The slag receiving chamber 214 may be mounted on the liquid storage case 21 by a separate member, or the slag receiving chamber 214 may be directly formed by the liquid storage case 21. The communication between the opening of the slag receiving chamber 214 and the first air inlet 152a is achieved by disposing the slag receiving chamber 214 opposite to the first air inlet 152 a. By providing the slag accommodating chamber 214, the slag, condensate, and the like generated thereabove can fall into the slag accommodating chamber 214, and thus prevented from falling into the first air flow passage 213 of the liquid storage case 21; additionally, the left side of the slag receiving cavity 214 may also be positioned adjacent to or in alignment with the left side wall of the second channel 152 so that condensate on the left side wall may flow into the slag receiving cavity 214. Further, by providing the atomization assembly 20 as a replaceable unit, the collected slag, condensate, etc. within the slag-receiving chamber 214 may be removed as the atomization assembly 20 is replaced; the slag receiving cavity 214 of the replaced atomization assembly 20 may continue to be used to collect slag, condensate, and the like. In addition, as shown in fig. 5, 10 and 12, the first air outlet 213a of the first air flow channel 213 is located at one side of the smoke residue containing chamber 214; further, the first outlet port 213a may be flush with, i.e., in the same plane as, the opening of the clinker accommodating chamber 214.

In some embodiments, as shown in conjunction with fig. 3 and 5, the first gas flow channel 213 of the atomizing assembly 20 has the first gas outlet 213a, and the lower end cap 151 of the solid substrate heating assembly 10 has the first gas inlet 152 a; the first air outlet 213a is in direct fluid communication with the first air inlet 152a such that the second aerosol can enter the solid substrate heating assembly 10 and mix with the first aerosol.

In some embodiments, as shown in conjunction with fig. 3-5 and 14, the solid substrate heating assembly 10 may further include an upper end cap 141, the upper end cap 141 defining a first channel 142. The two ends of the heating substrate 11 are respectively connected with the upper end cover 141 and the lower end cover 151 in a sealing manner. For example, the upper end of the heating base 11 may be inserted into the lower end of the upper cap 141, and the first sealing member 19 is disposed therebetween; the lower end of the heating base 11 is inserted outside the upper end of the lower end cap 151, and a first sealing ring 17 is disposed therebetween. The lower end cover 151, the heating substrate 11 and the upper end cover 141 are communicated in sequence; that is, the gas may flow through the second channel 152, the receiving bin 111, and the first channel 142 in sequence.

In a further embodiment, as shown in fig. 3, 5 and 21, a third orthographic projection of the second air outlet 152b on a first plane, which is a plane perpendicular to the up-down direction, overlaps at least 50% with a fourth orthographic projection of the slag accommodating chamber 214 on the first plane. The overlap may be, for example, 60%, 70%, 80%, 90%, 100%, etc. It will be readily appreciated that the greater this degree of overlap means that the more the slag receiving chamber 214 corresponds to the second air outlet 152b, so that the better the collection of impurities such as soot and ash that fall downwardly through the second air outlet 152 b.

Further, as shown in connection with fig. 3 and 5, the solid substrate heating assembly 10 may have a transition section located at least between the first air inlet 152a and the lower end of the holding bin 111, which defines the second channel 152. The second channel 152 is located at least between the first air outlet 213a and the holding chamber 111, and is used for conveying the second aerosol output through the first air outlet 213a to the holding chamber 111. The second channel 152 has a smooth transition inner surface; the accommodating chamber 111, the second passage 152 and the first air flow passage 213 are directly communicated in this order from top to bottom. By providing the second channel 152 with a smooth transition inner surface, for example, a smooth transition inner surface from the first air inlet 152a to the second air outlet 152b, the second aerosol output through the first air flow channel 213 can be smoothly transported within the second channel 152 and thus into the first substrate 201. In addition, the length of the second channel 152 in the axial direction may be greater than the diameter of the accommodating chamber 111, so that the cross-sectional area of the second channel 152 may gradually change along the axial direction, thereby providing a smooth transition inner surface. For example, the length of the second channel 152 in the axial direction may be between 1.1 and 2 times the diameter of the cartridge 111. In addition, when the second passage 152 is defined by the lower end cap 151, the length of the lower end cap 151 in the axial direction may be greater than the diameter of the cartridge 111.

In a further embodiment, as shown in connection with fig. 15 and 16, the outside of the heated substrate 11 includes coated regions 115 and uncoated regions 116. For example, the heated substrate 11 includes a proximal end 112 and a distal end 113 and a first surface 114 extending between the proximal end 112 and the distal end 113, the first surface 114 including a coated region 115 and a non-coated region 116 disposed proximate the distal end 113. The infrared electrothermal coating 12 is formed within the coating region 115. The first electrode 13 and the second electrode 13a each include a coupling electrode 131 disposed in the non-coated region 116 and a strip electrode 132 extending from the coupling electrode 131 toward the other end of the heating substrate 11 (e.g., the proximal end 112). The strip-shaped electrodes 132 of the first electrode 13 and the strip-shaped electrodes 132 of the second electrode 13a are both located at least partially within the coating region 115 to form an electrical connection with the infrared electrothermal coating 12. The non-coated region 116 is disposed proximate the distal end 113 of the heated substrate 11. Typically, the length of the uncoated region 116 in the axial direction may be in the range of 0.5mm to 7mm, for example, 0.5mm, 0.9mm, 1mm, 1.5mm, 2mm, 3mm, 3.5mm, 4mm, 5mm, 7mm, and the like. As shown in fig. 14, the proximal end 112 may be an end of the heating substrate 11 near the upper end cap 141, that is, an upper end of the heating substrate 11; the distal end 113 is the opposite end, i.e., the lower end of the heating substrate 11. In other cases, the proximal end 112 may also be defined as the lower end of the heated substrate 11; the distal end 113 is the upper end of the heated substrate 11.

In addition, the width of the stripe-shaped electrode 132 may be in the range of 0.5 to 7mm, for example, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 3mm, 3.5mm, 4mm, 6mm, 7mm, etc. Further, the strip-shaped electrodes 132 may be made to have a wide width, for example, a width of 1.5mm or more; through setting up the width of broad, can reduce the resistance of tubulose heating member 10a, can increase the ability that the electrode can bear the heavy current, avoid the risk that the electrode line burns out in the heating process, still can reduce the resistance of electrode line, make electric current distribution more even on the axis direction, it is more even to reach the thermal field that generates heat. It is noted that if the width of the strip-shaped electrodes 132 is too wide, it is liable to cause a reduction in the heat emitting surface, i.e., a reduction in the heating area, so that the infrared radiation may be reduced. Therefore, a preferable width range may be 2 to 4mm, which can reduce the resistance value of the tubular heating element 10a without reducing the heating area.

The first electrode 13 and the second electrode 13a are at least partially electrically connected with the infrared electrothermal coating 12, so that current can flow from one electrode to the other electrode through the infrared electrothermal coating 12. The first electrode 13 and the second electrode 13a are opposite in polarity, for example: the first electrode 13 is a positive electrode, and the second electrode 13a is a negative electrode; alternatively, the first electrode 13 is a negative electrode and the second electrode 13a is a positive electrode. In some examples, the first electrode 13 and the second electrode 13a are conductive coatings, the conductive coatings may be metal coatings or conductive tapes, and the like, and the metal coatings may include silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or metal alloy materials thereof. In one example, the first electrode 13 and the second electrode 13a are symmetrically disposed along a central axis of the heating substrate 11.

In other embodiments, the first electrode 13 and the second electrode 13a may be conductive coatings respectively coated on the upper and lower sides of the heating substrate 11, and the infrared electrothermal coating 12 is located between the two conductive coatings. The conductive coating can be made of silver powder coating, and the conductive coating is in contact with the infrared electrothermal coating 12.

The heating substrate 11 may have a cylindrical shape, a prismatic shape, or another cylindrical shape. When the heating substrate 11 is cylindrical, the accommodating chamber 111 is a cylindrical hole penetrating through the middle of the heating substrate 11, and the inner diameter of the hole can be slightly larger than the outer diameter of the aerosol-forming product, so that the aerosol-forming product can be conveniently placed in the cavity to be heated. The heating substrate 11 may be made of a transparent material such as quartz glass, ceramic, or mica, which is resistant to high temperature, or may be made of other materials having a high external light transmittance, for example: the high temperature resistant material having an infrared transmittance of 95% or more is not particularly limited.

It is easy to understand that, through coating infrared electric heat coating 12 outside heating base member 11, infrared electric heat coating 12 after the circular telegram sends the infrared light, and the infrared light pierces through heating base member 11 and comes radiant heating to be located in heating base member 11 first substrate 201 of for example smoking substance, because the infrared light has stronger penetrability, can pierce through peripheral smoking substance and get into inside for the heating to smoking substance is comparatively even.

In addition, as shown in fig. 3, 9 and 14, the solid substrate heating assembly 10 may further include a Temperature sensor 10b, such as an NTC (Negative Temperature Coefficient) Temperature sensor, for detecting a real-time Temperature of the heating substrate 11 and transmitting the detected real-time Temperature to the circuit board 41, wherein the circuit board 41 may adjust the magnitude of the current flowing through the infrared electrothermal coating 12 according to the real-time Temperature. The temperature sensor 10b may be connected to the circuit board 41 through a wire 16 b.

In addition, as shown in fig. 6, 12 and 13, the mounting assembly of the atomizing assembly 20 may further include a second mounting member 27. The second mounting member 27 is disposed in the first mounting space 212 and can be snap-fitted to the reservoir housing 21 to support and fix the first mounting member 24 and the liquid guiding member 22.

In some embodiments, as shown in fig. 3 and fig. 7 to 9, the housing assembly 30 of the electronic atomization device 100 may include a housing case 31, a detachable bottom cover 32, a sliding cover structure 33, and the like. The sliding cover structure 33 can be installed on the top of the housing case 31 to open or close the cigarette insertion opening of the electronic atomization device 100, i.e. the top socket 311, by sliding back and forth. The power supply assembly 40 of the electronic atomization device 100 can include a circuit board 41, a battery 42 and the like. The solid substrate heating assembly 10, atomizing assembly 20, circuit board 41 and battery 42 may all be disposed within the housing shell 31. The solid substrate heating assembly 10 is positioned above the atomizing assembly 20, and the circuit board 41 and battery 42 are positioned on one side of the solid substrate heating assembly 10 and the atomizing assembly 20. For example, the circuit board 41 and battery 42 may each be vertically positioned and located to the right of the entirety formed by the solid substrate heating assembly 10 and the atomizing assembly 20; the circuit board 41 may be located between the entirety of the solid substrate heating assembly 10 and the atomizing assembly 20 and the battery 42, and may be perpendicular to the plane of the solid substrate heating assembly 10 and the atomizing assembly 20 and the battery 42. With such an arrangement, the electronic atomization device 100 has a compact structure and a reasonable layout, and the whole device can be substantially in a flat rectangular parallelepiped shape.

In a further embodiment, as shown in connection with fig. 3, 7 and 8, the receptacle housing 31 defines a top receptacle 311 and a bottom receptacle 312. The top socket 311 is in communication with the receiving cavity 111 of the solid substrate heating assembly 10 for inserting the first substrate 201 in solid state into the receiving cavity 111 via the top socket 311. The atomizing assembly 20 is disposed to be able to be placed in the housing case 31 through the bottom socket 312. So configured, it is convenient to insert the solid first substrate 201 and the atomizing assembly 20 from two different directions, one above the other.

In addition, as shown in fig. 7 and 8, the detachable bottom cover 32 can be attached to the bottom of the housing case 31 and hold the atomizing assembly 20 in the housing case 31. For example, one end of the detachable bottom cover 32 may have a snap structure 323 such as a snap, and the other end may have a magnetic member 324; therefore, the detachable bottom cover 32 can be mounted on the bottom of the housing case 31 by engaging the engaging structure 323 at one end of the detachable bottom cover 32 with, for example, a slot of the housing case 31 and magnetically fixing the magnetic member 324 at the other end with the magnetic member mounted on the housing case 31. In this manner, the atomizing assembly 20 in the form of an atomized cartridge is accessible by opening and closing the bottom removable cover 32; for example, the first substrate 201 of the cigarette is taken from the top of the electronic atomization device 100, and the two substrates are not interfered with each other, so that the electronic atomization device 100 is simple and convenient in layout and more suitable for man-machine operation.

In a further embodiment, as shown in fig. 10 and 13, the atomizing assembly 20 further includes a first electrode tip 25, and the first electrode tip 25 is electrically connected to the heating element 23 of the atomizing assembly 20. The number of the first electrode needles 25 may be two, so as to be connected to two electrodes of the heating element 23, respectively. As shown in fig. 7, the battery 42 may also be electrically connected to the second electrode thimble 43, for example, the second electrode thimble 43 is mounted on the circuit board 41 and connected to the battery 42 through the circuit board 41; the number of the second electrode pins 43 may be two, so as to be connected to two electrodes of the battery 42, respectively. The detachable bottom cover 32 is provided with a conductive converting element 321, the conductive converting element 321 may be a conductive strip fixed on the upper side of the detachable bottom cover 32, and the number of the conductive strips may be two. Wherein, when the detachable bottom cover 32 holds the atomizing assembly 20 in the receiving case 31, the conductive converting element 321 is in conductive contact with the first electrode tip 25 and the second electrode tip 43. The first electrode pin 25 and the second electrode pin 43 may be elastic pins to enhance the contact effect with the conductive adaptor 321.

In other embodiments, the two electrodes of the heating element 23 in the atomizing assembly 20 can also be directly connected to the circuit board 41 through wires, for example, the two electrodes of the heating element 23 can be connected to the circuit board 41 by soldering. This case can be applied to a product which does not require replacement of the atomizing assembly 20, thereby simplifying the wiring structure and reducing the cost.

In a further embodiment, as shown in fig. 2 and 7, the detachable bottom cover 32 is provided with one or more air inlet holes 322, and the number of the air inlet holes 322 may be one or more. When the bottom cover 32 holds the atomizing assembly 20 in the housing case 31, the air inlet hole 322 is in gas communication with the atomizing assembly 20. That is, by providing the air inlet hole 322, the external air can enter the inside of the electronic atomization device 100 through the air inlet hole 322 and flow through the atomization assembly 20, the solid substrate heating assembly 10 and the top socket 311 in sequence. Since the solid substrate heating assembly 10 and the atomizing assembly 20 share one air inlet 322, it is ensured that most of the liquid atomized smoke can enter the first substrate 201, such as a cigarette, heated by the solid substrate heating assembly 10, which can improve TPM (Total particulate matter) and smoking taste of the mixed smoke.

In some embodiments, as shown in conjunction with fig. 14 and 17-19, the solid substrate heating assembly 10 may further include a clamping member 146, and the upper end cap 141 and the clamping member 146 form a clamping structure 14. Wherein the clamping member 146 comprises an elastic body 147 and at least one abutment 148 connected to the elastic body 147; the resilient body 147 can fit over the outside of the upper end cap 141 and each abutment 148 can be disposed on the inside of the resilient body 147 that can pass through the side wall of the upper end cap 141 and serve to abut the first substrate 201, e.g., in the form of a cigarette, within the first channel 142. For example, the number of the abutting portions 148 may be one or more, and may be three as shown in fig. 17, and the three abutting portions 148 may be evenly distributed in the circumferential direction along the elastic body 147.

In the electronic atomization device 100 of this embodiment, the clamping member 146 is assembled with the upper end cap 141 by sleeving the elastic body 147 on the outer side of the upper end cap 141 and passing the abutting portion 148 through the sidewall of the upper end cap 141, so that the clamping of the first substrate 201 is realized by a two-piece assembly structure; moreover, when the first substrates 201 of different hardness are inserted, the elastic force of the abutment portion 148 is adjusted in accordance with the outward deformation of the outer elastic body 147, thereby preventing the deformation of the first substrate 201 due to an excessive clamping force of the abutment portion 148.

In some embodiments, as shown in fig. 14 and 17 to 19, at least one bracket through hole 143 is formed on a sidewall of the upper end cap 141, and each bracket through hole 143 is used for passing through one abutting portion 148. Each holder through hole 143 may be provided to guide the abutment 148 therein to move in a radial direction of the first channel 142. The number and positions of the holder through holes 143 correspond to the abutment portions 148. Further, the holder through hole 143 may extend in a circumferential direction of the upper cover 141. Each bracket through-hole 143 may have opposite upper and lower surfaces 143a and 143 b. The upper and lower surfaces 143a and 143b may be parallel to each other, or may gradually approach each other as approaching the inside of the upper cap 141. The bracket through hole 143 and the abutment 148 may be loosely fitted to allow the abutment 148 to move freely in a radial direction.

In some embodiments, as shown in fig. 18 to 19, the inner side of the upper end cap 141 includes a first inner surface portion 144a and a second inner surface portion 144b, and the first inner surface portion 144a and the second inner surface portion 144b are connected in the circumferential direction of the upper end cap 141. The first inner surface portion 144a may be located within a first cylinder having a first diameter and the second inner surface portion 144b may be located within a second cylinder having a second diameter, the first diameter being greater than the second diameter. The end of the abutment 148 projects beyond the first inner surface portion 144a and projects radially inwardly of the first channel 142 beyond the second inner surface portion 144 b. Thus, the ends of the abutment 148 can be used to grip the first substrate 201 and facilitate insertion and extraction of the first substrate 201 into and from the holding structure 14.

In another embodiment, as shown in fig. 18 to 19, the inner side of the upper end cap 141 may include a second inner surface portion 144b, and the second inner surface portion 144b is located in a second cylindrical surface having a second diameter, which is the minimum diameter of the inner side of the upper end cap 141. The tip of the abutment portion 148 protrudes beyond the second inner surface portion 144b in the free state. Upon insertion of a first substrate 201, such as a cigarette, the resilient body 147 is resiliently deformable by movement of the abutment 148 and, upon resilient deformation, allows the end of the abutment 148 to move radially outwardly of the first channel 142 into at least alignment with the second inner surface portion 144 b. Thus, the abutment 148 may have a greater range of radial movement.

In some embodiments, as shown in fig. 17 and 19, the outer side of the upper cover 141 is provided with a bracket groove 145 extending along the circumferential direction of the upper cover 141. The bracket recess 145 receives the elastic body 147 and allows the elastic body 147 to move in a direction away from the first passage 142. In this way, while the holder groove 145 receives the elastic body 147, the elastic body 147 is prevented from moving in the axial direction of the upper end cap 141, which is equivalent to mounting the elastic body 147 on the upper end cap 141 through the holder groove 145.

In some embodiments, as shown in connection with fig. 17-19, the upper end cap 141 is hollow cylindrical and defines a first passageway 142. Additionally, the resilient body 147 may be resilient annular, such as an O-ring. Further, the abutting portion 148 may be an elastic material or a hard material, for example, the elastic material may be an elastic rubber, especially a silicon rubber, so as to clamp the first substrate 201 of, for example, a cigarette by the friction force generated by the flexible deformation of the abutting portion 148; the rigid material may be metal or rigid plastic. Further, the abutment 148 may extend in the circumferential direction of the elastic body 147, that is, the abutment 148 may have a flat shape in order to increase a contact area and a frictional force to the first substrate 201.

In some embodiments, as shown in conjunction with fig. 17, the resilient body 147 and the abutment 148 can be an integrally formed structure. For example, the holding member 146 may be formed by injection molding a silicone material at one time. In addition, when the abutment portion 148 is made of a hard material, the clamping member 146 may be manufactured by a process such as overmolding or insert molding. The integral structure can simplify the manufacturing process, and the manufactured clamping component 146 has a better clamping effect.

In some embodiments, as shown in conjunction with fig. 14 and 17, the clamping member 146 is disposed adjacent to the heating substrate 11 of the tubular heating element 10 a. That is, the clamping member 146 may be disposed at a lower position of the upper cap 141, thereby more effectively clamping the first substrate 201.

In some embodiments, as shown in conjunction with fig. 14 and 20-22, the solid substrate heating assembly 10 may further include a removable first sleeve 156, and the lower end cap 151 and the removable first sleeve 156 form an end cap structure 15. Wherein, the lower end cover 151 is used for matching and connecting with the tubular heating element 10 a; for example, the lower end of the tubular heating element 10a may be supported by the top surface of the lower cap 151, and a sealing member may be disposed therebetween. The detachable first sleeve 156 is sleeved on the lower end cap 151, and forms a gap with the lower end cap 151. The first sleeve 156 serves to clamp the electrode contact spring 16 to the lower end cap 151 and to bring the electrode contact spring 16 into electrically conductive contact with the tubular heating element 10 a.

In the electronic atomization device 100 of this embodiment, the electrode contact spring 16 may be first installed on the lower end cap 151, and then the first sleeve 156 is sleeved on the lower end cap 151, so as to clamp the electrode contact spring 16 between the first sleeve 156 and the lower end cap 151. This configuration further facilitates electrically connecting the electrode contact spring 16 and the lead 16a by welding or clamping, and then clamping the electrode contact spring 16 in the end cap structure 15.

In some embodiments, as shown in fig. 20 to 21, the lower cover 151 may include an insertion end 151a, and the insertion end 151a is configured to be inserted into the tubular heating element 10 a. Further, the insertion end 151a is provided with a first circumferential groove 151b, the first circumferential groove 151b being adapted to receive the first sealing ring 17. Thus, when the lower end of the heating base 11 is inserted outside the insertion end 151a of the lower cap 151, sealing is achieved by the first packing 17 provided, preventing gas from leaking through the gap between the insertion end 151a and the heating base 11. Moreover, through setting up the first circumferential groove 151b that can receive first sealing washer 17, can overcome the difficult problem that realizes of mould, the storehouse 111 that holds of heating base member 11 like this can seal through the circumference compression of the first sealing washer 17 of silica gel for example completely for the assembly is more reliable, simple, stable, has also avoided because of the sealed problem that assembly error brought.

Further, as shown in fig. 14 and 21, the lower end cap 151 further includes a middle section 151c, and the middle section 151c is connected to the insertion end 151 a; the intermediate section 151c is configured to have a cross-sectional dimension greater than the insertion end 151 a. The middle section 151c has a first supporting surface 151d extending radially outward from the insertion end 151a, and the first supporting surface 151d is used for supporting an end surface of the tubular heating element 10a, that is, a lower end surface of the tubular heating element 10 a. In addition, the gap between the first bushing 156 and the middle section 151c is used to receive a portion of the electrode contact spring 16, i.e., a lower end portion of the electrode contact spring 16; thus, the lower end portion of the electrode contact spring 16 can be held stationary, while the upper end portion of the electrode contact spring 16 can be used for electrically conductive contact with the tubular heating member 10 a.

As shown in fig. 21 and 22, a first protrusion 151e is disposed on an outer peripheral side of the middle section 151c, and the first protrusion 151e is configured to be in stop fit with the first groove 162 in the electrode contact spring 16, so as to prevent the electrode contact spring 16 from axially separating from the middle section 151 c. In addition, the outer circumference of the middle section 151c may be provided with a first recess 151f, and the first recess 151f may receive the lead connection portion 167 of the electrode contact spring 16. As shown in fig. 20, the lead connection portion 167 may be electrically connected to the lead 16a by soldering or clamping.

In some embodiments, as shown in conjunction with fig. 14 and 21, the bottom cap 151 further includes a base end 151g opposite the insertion end 151 a. The base end 151g has a second support surface 151h extending radially outward from the lower end cap 151, and the second support surface 151h is configured to support an end surface of the first sleeve 156, i.e., a lower end surface of the first sleeve 156.

Further, as shown in fig. 14 and 21, the base end 151g further has a third supporting surface 151i extending radially outward from the lower end cap 151, and the third supporting surface 151i is used for supporting an end surface, i.e., a lower end surface, of the insulating tube 18. As shown in fig. 3, the heat insulation pipe 18 is disposed in the housing case 31 of the housing assembly 30, is disposed outside the tubular heating element 10a, and is connected to the lower end cap 151; the insulated duct 18 may prevent a significant amount of heat from being transferred to the housing assembly 30 and causing the user to feel hot. The insulating tube 18 comprises an insulating material which may be an insulating gel, aerogel blanket, asbestos, aluminum silicate, calcium silicate, diatomaceous earth, zirconia, or the like. The heat insulation pipe may be a vacuum heat insulation pipe. An infrared reflective coating may also be formed in the heat insulation pipe 18 to reflect infrared rays emitted from the infrared electrothermal coating on the heating substrate 11 back to the infrared electrothermal coating 12, thereby improving heating efficiency.

In addition, as shown in fig. 20 and 21, the base end 151g is further provided with a second circumferential groove 151j, the second circumferential groove 151j being configured to receive the second seal ring 17 a. For example, the lower end of the insulating tube 18 may be fitted over the base end 151g such that the third supporting surface 151i supports the end surface of the insulating tube 18. Thus, the second gasket 17a may function to seal the gap between the insulated pipe 18 and the base end 151g for better insulation.

Further, the base end 151g may be further provided with a lead groove 151k, and the lead groove 151k is recessed inward from an outer surface of the base end 151 g. As shown in fig. 14 and 20, the lead groove 151k communicates with the first recess 151f, and is used for receiving the connection end of the lead 16a, and guiding the received lead 16a to bend and change the direction toward the base end 151g, so as to be connected to the circuit board 41 of the power supply module 40.

In some embodiments, as shown in connection with fig. 14 and 21, the lower end cap 151 is hollow and defines a second channel 152. The second channel 152 is adapted to be in air flow communication with the holding bin 111 and the first channel 142.

In some embodiments, as shown in fig. 22, the electrode contact spring 16 may include a spring body 161 and a lead connection portion 167. The spring plate main body 161 is used for electrically contacting with the electrode; for example, the dome body 161 of one electrode contact dome 16 may be in electrically conductive contact with the first electrode 13 on the heating substrate 11 of the solid substrate heating assembly 10, and the dome body 161 of the other electrode contact dome 16 may be in electrically conductive contact with the second electrode 13a on the heating substrate 11 of the solid substrate heating assembly 10. The lead connecting portion 167 is connected to the spring main body 161, and the lead connecting portion 167 is configured to clamp a lead 16a by deformation.

In the electronic atomizer 100 of this embodiment, by arranging the lead connecting portion 167 to be deformable to clamp the lead 16a, one end of the lead 16a may be inserted into the groove of the lead connecting portion 167 first during the assembly process, and then the lead connecting portion 167 may be pressed down by a jig to be deformed to fix the lead 16 a. The assembling mode can be completely processed outside a production line, and can be completely used as a part during assembling and disassembling, so that a complicated welding process is avoided.

In some embodiments, as shown in fig. 22, the clip body 161 may define two first grooves 162 and have a first connecting bar 163 located between the two first grooves 162, and the lead connection 167 is connected to the first connecting bar 163. For example, the first recess 162 may be punched to form two portions of the lead connecting portion 167, and then the two portions are bent to form the lead connecting portion 167 as shown in fig. 22.

In some embodiments, as shown in fig. 22, the lead connection portion 167 includes a first bending portion 168 and a second bending portion 168a, and the first bending portion 168 and the second bending portion 168a enclose a lead receiving space.

Further, the end of the first bent portion 168 and the end of the second bent portion 168a may be disposed to face each other. Therefore, when fixedly connected to the lead 16a, the first bent portion 168 and the second bent portion 168a are crushed, and the lead 16a is clamped in the lead housing space and electrically contacted to the lead connecting portion 167.

Alternatively, the end of the first bent portion 168 and the end of the second bent portion 168a may be disposed close to each other, and both the end of the first bent portion 168 and the end of the second bent portion 168a face the lead wire receiving space. Therefore, when the lead 16a is fixedly connected, the first bending portion 168 and the second bending portion 168a can be pressed down by a jig to be deformed, so that the end of the first bending portion 168 and the end of the second bending portion 168a are forced to be pressed on the lead 16a, and the lead 16a can be more firmly fixed.

In some embodiments, as shown in fig. 22, the spring body 161 is provided with a flexible cantilever 164 at an end away from the lead connection 167, and a conductive contact 164a is formed near an end of the flexible cantilever 164. The number of the elastic cantilever 164 may be one or more, and may be formed by punching. The conductive contact 164a is for making conductive contact with the electrode. In addition, the conductive contact 164a and the lead connection portion 167 are located on the same side of the spring main body 161. Further, the spring main body 161 may be curved as a whole so as to match the structure of the tubular first sleeve 156 and the tubular heating element 10 a.
