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 invention 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 atomizer device 100 may generally include an infrared heating assembly 10, a liquid atomizer assembly 20, a housing assembly 30, and a power supply assembly 40. The housing assembly 30 houses the infrared heating assembly 10, the liquid atomizing assembly 20 and the power supply assembly 40, the power supply assembly 40 including portions for providing electrical power to the infrared heating assembly 10 and the liquid atomizing assembly 20 as needed for operation thereof, and further including portions for controlling operation of the infrared heating assembly 10 and the liquid atomizing assembly 20.

The infrared heating assembly 10 is used for generating infrared rays to radiatively heat the solid first substrate 201 and generate the first aerosol. The first substrate 201, which may also be referred to as an aerosol-generating article, may be in the form of a cigarette, for example, having an internal airflow path. The liquid atomizing assembly 20 is used to atomize a liquid second substrate 202, such as tobacco tar, liquid medicine, etc., and generate a second aerosol. The liquid atomizing assembly 20 and the infrared heating assembly 10 are in fluid communication such that the second aerosol can enter and pass over the first substrate 201 and mix with the first aerosol. When the nebulized product of the first substrate 201 and the second substrate 202 has a respiratory tract therapeutic effect, the electronic nebulizing device 100 may be referred to as a respiratory tract electronic nebulizer; 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 atomization device 100 of this embodiment, by using the liquid atomization assembly 20 and the infrared heating assembly 10, the second substrate 202 such as tobacco tar and the first substrate 201 such as tobacco rod can be atomized simultaneously; moreover, the liquid atomizing assembly 20 is in fluid communication with the infrared heating assembly 10, so that the second aerosol generated after the liquid second substrate 202 is atomized enters the first substrate 201 heated by the infrared heating assembly 10 along the communicating air passage, and is mixed with the first aerosol generated after the first substrate 201 is heated by the infrared radiation and output. In addition, since the infrared heating element 10 generates infrared light with high transmittance during operation, the infrared light can penetrate through the peripheral first substrate 201 and enter the interior, so that the first substrate 201 is heated more uniformly.

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

In some embodiments, as shown in conjunction with fig. 3, the electronic atomizing device 100 defines a thermal chamber 111, and the thermal chamber 111 is configured to receive the first substrate 201. The heated cartridge 111 may be defined by a housing member of the electronic atomization device 100. The liquid atomization assembly 20 is in fluid communication with the heating chamber 111. Because the liquid atomization assembly 20 is in fluid communication with the heating chamber 111, a second aerosol can enter the heating chamber 111; accordingly, when a first substrate 201, such as a cigarette, is placed within the heating chamber 111, a second aerosol can enter the interior of the first substrate 201 as the user draws. Since the heating chamber 111 is used to house the first substrate 201, it may be also referred to as a housing chamber.

Furthermore, when there is a gap or flow channel between, for example, the first substrate 201 of a cigarette and the peripheral side of the cartridge 111, the second aerosol can also enter such a gap or flow channel.

In other embodiments, the first aerosol generated by the infrared heating assembly 10 and the second aerosol generated by the liquid atomizing assembly 20 may be delivered in parallel and may be mixed prior to entering the mouthpiece of the electronic atomizing device 100. For example, the electronic atomization device 100 can be configured to include a mouthpiece for a user to draw and a mixing channel; the mixing channel is in communication with the suction nozzle. The mixing channel may also be in direct or indirect communication with the infrared heating assembly 10 and the liquid atomizing assembly 20, such that the second aerosol and the first aerosol can enter the mixing channel separately and mix. Further, the infrared heating assembly 10 may be in communication with the external atmosphere through a first air inlet channel, and the liquid atomization assembly 20 may be in communication with the external atmosphere through a second air inlet channel. The first and second intake passages may have the same or different intake ports.

In some embodiments, as shown in conjunction with fig. 3, the liquid atomization assembly 20 defines a first air flow channel 213, and the second aerosol generated by the liquid atomization assembly 20 is delivered to the heating chamber 111 of the infrared heating assembly 10 through the first air flow channel 213. Wherein the first air flow channel 213 extends along the up-down direction A1 so as to be disposed in parallel with the heating chamber 111 and directly communicates with the first air inlet 152a (see fig. 5) of the infrared heating assembly 10; in this way, the second aerosol can be smoothly output from the first linear airflow channel 213 and then conveyed toward the heating 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 heating chamber 111, but may have various shapes such as bending, curving, and the like.

Further, the first air flow channel 213 is in communication with a heating cartridge 111, and the first air flow channel 213 may be configured as the sole source of air intake for the heating cartridge 111. Since the first air flow channel 213 is directly and exclusively communicated with the first air inlet 152a of the infrared heating assembly 10, the atomized second aerosol can enter the first substrate 201 as air of the infrared heating assembly 10, so that the first aerosol is sufficiently discharged and mixed-flavor smoke is generated.

Further, as shown in connection with fig. 3 and 5, the infrared heating assembly 10 may have a transition section at least between the first inlet 152a and the lower end of the heating chamber 111, which defines at least part of the second channel 152, the second channel 152 having a smooth transition inner surface; the heating chamber 111, the second channel 152 and the first air flow channel 213 are sequentially connected, for example, may be directly connected from top to bottom. By providing the second channel 152 with a smooth transition inner surface, the second aerosol output through the first aerosol flow channel 213 can be smoothly transported within the second channel 152 and thus into the first substrate 201. In some embodiments, the length of the second channel 152 in the axial direction may be greater than the diameter of the heating cartridge 111. 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 heating chamber 111.

In some embodiments, as shown in conjunction with fig. 3 and 14-16, the infrared heating assembly 10 is in the form of circumferential heating. For example, the infrared heating assembly 10 defines the heating chamber 111, and the heating chamber 111 is a hollow space for accommodating the first substrate 201 in a solid state. The solid first substrate 201 may be in the form of a cigarette, for example. The infrared heating assembly 10 includes an infrared electrocaloric coating 12, the infrared electrocaloric coating 12 configured to receive heat generated by electrical power to generate infrared light for radiative heating of the solid first substrate 201.

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 8-15 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 oxide ceramic layer, an iron nitride ceramic layer, an iron boride ceramic layer, an iron 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 some embodiments, as shown in conjunction with fig. 14-16, the infrared heating assembly 10 can include a tubular heating element 10a, and the tubular heating element 10a can include a heating substrate 11, an infrared electrothermal coating 12, a first electrode 13, and a second electrode 13a. The heating base 11 may be hollow, and a heating chamber 111 for receiving the first substrate 201 is formed therein. 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 13a. 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 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 in 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 stripe-shaped electrode 132 extending from the coupling electrode 131 toward the other end (e.g., the proximal end 112) of the heating substrate 11. 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 range from 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 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 heating 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 heat the aerosol-forming product. 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 heats the first substrate 201 such as the smoking substance that is located in heating base member 11 by radiation, because the infrared light has stronger penetrability, can pierce through peripheral smoking substance and get into inside for the heating to the smoking substance is comparatively even.

In addition, as shown in fig. 3, 9 and 14, the infrared 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 some embodiments, as shown in fig. 3-5 and 14, the infrared heating assembly 10 further comprises an upper end cap 141 and a lower end cap 151, the upper end cap 141 defining at least part of the first channel 142, and the lower end cap 151 defining at least part of the second channel 152. 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 passage 152, the heating chamber 111, and the first passage 142 in sequence.

In other embodiments, the infrared heating assembly may be a combination of center heating and circumferential heating. For example, the infrared heating unit may include the above-described heating element for insertion into the first substrate 201, and the tubular heating element 10a for housing 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 liquid atomization assembly 20 includes a reservoir 21, a wicking 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-conducting 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. The heating element 23 is disposed on the atomization surface 221, and is configured to heat at least a portion of the second substrate 202 absorbed by the liquid guide element 22 when the electric current is applied to generate aerosol, and the aerosol is released after escaping from the atomization surface 221. 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 containing 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. As mentioned above, 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 liquid atomizing assembly 20 may be ultrasonically atomized and associated structures, or molecularly resonant atomized and associated structures; 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 liquid atomization assembly 20 further includes a mounting assembly for mounting the aforementioned wicking 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 liquid atomizing assembly 20 is used to be conveyed to the infrared heating assembly 10 through 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.

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 and 5, the first air flow channel 213 of the liquid atomizing assembly 20 has a first air outlet 213a, and the lower end cap 151 of the infrared heating assembly 10 has a first air inlet 152a; the first air outlet 213a is in direct fluid communication with the first air inlet 152a such that the second aerosol can enter the infrared heating assembly 10 and mix with the first aerosol; and, the first air outlet 213a is eccentrically disposed with respect to the heating compartment 111. For example, the first air flow channel 213 and the heating chamber 111 can be both vertically disposed, and the first air flow channel 213 is disposed eccentrically to the heating chamber 111.

In the electronic atomizing device 100 of this embodiment, the infrared heating assembly 10 is located above the liquid atomizing assembly 20, so that the first air outlet 213a is directly in fluid communication with the first air inlet 152a, and the first air outlet 213a is eccentrically disposed with respect to the heating chamber 111, so as to avoid a problem that impurities such as smoke oil condensate and smoke residues generated in the air flow channel of the infrared heating assembly 10 directly fall into the air flow channel of the liquid atomizing assembly 20. Thus, the electronic atomization device 100 of this embodiment can provide a better smoking experience.

In a further embodiment, as shown in fig. 3 and 5, when projected along the up-down direction A1, a first orthographic projection of the inner side surface of the second channel 152 may overlap with a second orthographic projection of the first air outlet 213a by at least 50%, for example, by 60%, 70%, 80%, 90%, 100%, and so on. It will be readily appreciated that the higher the degree of overlap, i.e., the more interior side of the second channel 152 covers the first air outlet 213a, the better the prevention of impurities from falling directly into the first air flow channel 213 of the liquid atomization assembly 20.

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

In addition, as shown in fig. 6, 12 and 13, the mounting assembly of the liquid atomization assembly 20 can 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, 10 and 12, a smoke residue containing cavity 214 may be further provided on a side of the liquid storage case 21 facing the infrared heating assembly 10. The slag receiving chamber 214 may be installed 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 slag receiving cavity 214 is in direct fluid communication with 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 be prevented from falling into the first air flow passage 213 of the liquid storage case 21. Further, by providing the liquid atomization assembly 20 as a replaceable unit, the collected slag, condensate, etc. within the slag-receiving chamber 214 may be removed as the liquid atomization assembly 20 is replaced; the slag receiving cavity 214 of the replaced liquid atomizing assembly 20 may continue to be used to collect slag, condensate, etc. 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 a further embodiment, as shown in connection with fig. 3, 5 and 21, the second channel 152 also has a second air outlet 152b. The third orthographic projection of the second air outlet 152b overlaps at least 50% of the fourth orthographic projection of the slag containing cavity 214, such as 60%, 70%, 80%, 90%, 100% and the like, by projecting along the vertical direction A1. 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 152b.

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 infrared heating module 10, the liquid atomizing module 20, the circuit board 41 and the battery 42 may be disposed in the accommodating case 31. The infrared heating assembly 10 is positioned above the liquid atomizing assembly 20, and the circuit board 41 and the battery 42 are positioned on one side of the infrared heating assembly 10 and the liquid atomizing assembly 20. For example, the circuit board 41 and the battery 42 may each be vertically disposed and located on the right side of the assembly formed by the infrared heating assembly 10 and the liquid atomizing assembly 20; the circuit board 41 may be located between the entirety of the infrared heating assembly 10 and the liquid atomizing assembly 20 and the battery 42, and may be perpendicular to the plane in which the infrared heating assembly 10 and the liquid atomizing assembly 20 and the battery 42 are located. By such 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 heating chamber 111 of the infrared heating assembly 10 for inserting the first substrate 201 in a solid state into the heating chamber 111 through the top socket 311. The liquid atomization assembly 20 is configured to be placed in the containment housing 31 through the bottom socket 312. So configured, the insertion of the solid first substrate 201 and the liquid atomizing assembly 20 from two different directions, respectively, may be facilitated.

In addition, as shown in fig. 7 and 8, the detachable bottom cover 32 can be attached to the bottom of the accommodating case 31 and hold the liquid atomizing assembly 20 in the accommodating 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 liquid atomization 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 liquid atomizing assembly 20 further includes a first electrode needle 25, and the first electrode needle 25 is electrically connected to the heating element 23 of the liquid atomizing assembly 20. The number of the first electrode pins 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 the conductive conversion member 321 is in conductive contact with the first electrode needle 25 and the second electrode needle 43 when the detachable bottom cover 32 holds the liquid atomizing assembly 20 in the accommodating case 31. 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 of the liquid 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 with wires. This case can be applied to a product which does not require replacement of the liquid atomizing assembly 20, so that the wiring structure can be simplified and the cost can be reduced.

In a further embodiment, as shown in fig. 2 and 7, the detachable bottom cover 32 is provided with one or more air inlets 322, and the number of the air inlets 322 can be one or more. When the detachable bottom cover 32 holds the liquid atomization assembly 20 in the containing shell 31, the air inlet holes 322 are in gas communication with the liquid atomization 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 liquid atomization assembly 20, the infrared heating assembly 10 and the top socket 311 in sequence. Because infrared heating element 10 shares an inlet hole 322 with liquid atomizing component 20, guaranteed that the flue gas of liquid atomizing can mostly enter into infrared heating element 10 heated for example in the first substrate 201 of cigarette, this can promote the TPM (Total particulate matter) and the suction taste of mixing the flue gas.

In some embodiments, as shown in fig. 14 and 17-19, the infrared heating assembly 10 may further include a clamping member 146, and the upper cover 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 through hole 143 is provided on a sidewall of the upper end cap 141, and each 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 bracket through holes 143 correspond to the abutment 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 143b. The upper and lower surfaces 143a and 143b may be parallel to each other, or may gradually approach each other as approaching the inner side 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 connection with fig. 18-19, 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 144b. 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 connection with fig. 18 to 19, the inner side of the upper end cap 141 may include a second inner surface portion 144b, the second inner surface portion 144b being located within a second cylindrical surface having a second diameter, which is the smallest diameter of the inner side of the upper end cap 141. The tip of the abutment 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 144b. 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 proximate to the heating substrate 11 of the tubular heating element 10a. 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 fig. 14 and 20-22 in combination, the infrared 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 10a.

In the electronic atomization device 100 of this embodiment, the electrode contact spring 16 may be first mounted 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 10a. 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 heated warehouses 111 that heats base member 11 like this can seal through the circumference compression of the first sealing washer 17 of silica gel for example completely, make the assembly more reliable, simple, stable, also avoided because of the sealed problem that assembly error brought.

Further, as shown in fig. 14 and 21, the lower 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 10a. 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 10a.

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 151c. 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 reflection coating can be formed in the heat insulation pipe 18 to reflect infrared rays emitted by the infrared electrothermal coating on the heating substrate 11 back to the infrared electrothermal coating 12, so that the heating efficiency is improved.

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 17a. 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 151g. 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 passageway 152 is adapted to be in airflow communication with the heating chamber 111 and the first passageway 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 conductive contact with the first electrode 13 on the heating substrate 11 of the infrared heating assembly 10, and the dome body 161 of the other electrode contact dome 16 may be in conductive contact with the second electrode 13a on the heating substrate 11 of the infrared 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 16a. 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 10a.
