Description

Technical Field

[0001] This invention relates to the technical field of aerosol generating devices, and more particularly to a clamping structure and an electronic atomizing device employing such a clamping structure. Background Technology

[0002] An electronic atomizing device is an electronic product that atomizes liquids such as e-liquid or medicinal liquids, or atomizable substrates such as cigarettes, into an aerosol for inhalation.

[0003] When the atomizable matrix takes the form of a cigarette stick, the corresponding electronic atomizing device needs to have a clamping structure to hold the cigarette stick inserted into the electronic atomizing device.

[0004] However, current clamping structures still have some drawbacks. Some clamping structures have limited elastic deformation, making them unable to simultaneously accommodate various cigarette sizes. Furthermore, the clamping structure itself needs to be fixed within the electronic atomizing device; inappropriate fixing methods can also limit its elastic deformation. For example, situations requiring upper and lower fixing components to secure the clamping structure involve numerous assembly parts and significant cumulative tolerances during assembly, easily leading to misalignment of the clamping structure and making cigarette insertion difficult. Moreover, this fixing method, which fixes the clamping structure vertically, greatly restricts the range of elastic deformation adjustment, making it difficult to adapt to different cigarette sizes and potentially causing excessively tight clamping. Summary of the Invention

[0005] The present invention aims to provide a clamping structure and an electronic atomizing device, so as to provide a solution that can increase the elastic deformation of the clamping structure in the electronic atomizing device.

[0006] The present invention employs the following technical solution: a clamping structure comprising: a first support defining a first channel for receiving an aerosol-generated article; and a clamping component comprising an elastic body and at least one abutment portion connected to the elastic body. The elastic body is sleeved on the outside of the first support, and each abutment portion passes through the sidewall of the first support and abuts against the aerosol-generated article within the first channel.

[0012] As a further improvement to the above technical solution, the second diameter defines the maximum diameter of the aerosol-generated article.

[0013] As a further improvement to the above technical solution, the outer side of the first bracket is provided with a bracket groove extending circumferentially along the first bracket; the bracket groove accommodates the elastic body.

[0014] As a further improvement to the above technical solution, the elastic body is ring-shaped, and the abutting portion is evenly distributed along the elastic body.

[0015] As a further improvement to the above technical solution, the abutting part is made of an elastic material or a rigid material.

[0016] As a further improvement to the above technical solution, the abutting part also has at least one of the following features: the thickness of the abutting part gradually decreases inward in the radial direction of the first channel; the width of the abutting part gradually decreases inward in the radial direction of the first channel; or, the end of the abutting part has an arc-shaped surface.

[0017] As a further improvement to the above technical solution, the elastic body and the abutting part are integrally formed.

[0018] The present invention also employs the following technical solution: a clamping structure comprising: a first support defining a first channel for receiving an aerosol-generated article; and a clamping component, the clamping component being annular and comprising a first segment and a second segment connected to the first segment. The first segment is fixedly connected to the first support, the second segment abuts against the aerosol-generated article within the first channel, and the second segment is capable of elastic deformation to move radially outward within the first channel.

[0019] As a further improvement to the above technical solution, the second section includes an abutting part for abutting the aerosol-generated product in the first channel.

[0020] As a further improvement to the above technical solution, there are multiple first sections and multiple second sections, and the multiple first sections and multiple second sections are alternately arranged in the circumferential direction of the clamping component.

[0021] As a further improvement to the above technical solution, the first bracket is provided with a protruding portion that protrudes into the first channel, and the bracket through hole passes through the protruding portion.

[0022] As a further improvement to the above technical solution, the protruding portion includes a groove, and the through hole of the bracket passes through the groove.

[0023] As a further improvement to the above technical solution, in some cases during its elastic deformation, the second segment is further away from the first channel than the first segment.

[0024] The present invention also adopts the following technical solution: an electronic atomizing device, which defines a heating chamber and includes a clamping structure as described in any of the preceding claims, the clamping structure being disposed within the electronic atomizing device, and the first support being in communication with the heating chamber.

[0025] As a further improvement to the above technical solution, the electronic atomization device further includes: a solid matrix heating component for heating the aerosol-generating product and generating a first aerosol; and a liquid atomization component for atomizing a liquid second matrix and generating a second aerosol.

[0026] The beneficial effects of this invention are as follows: In the clamping structure and electronic atomizing device of this embodiment, the clamping component is assembled with the first support by sleeved elastic body on the outside of the first support and the abutment portion passing through the side wall of the first support. This allows the abutment portion to move different distances away from the first channel due to the elastic deformation of the elastic body, thereby adapting to the clamping needs of different cigarette sizes. Furthermore, by sleeved the clamping structure on the first support, the difficulty of component assembly is reduced, and the position of the clamping structure will not shift.

[0050] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0051] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0052] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Please see Figure 1 The diagram shows an exploded perspective view of a clamping structure 14 according to an embodiment of the present invention. The clamping structure 14 mainly includes a first support 141 and a clamping component 146. The first support 141 defines a first channel 142 for receiving an aerosol-generating article, such as a cigarette. The clamping component 146 includes an elastic body 147 and at least one abutment portion 148 connected to the elastic body 147. The elastic body 147 can be fitted onto the outside of the first support 141, and each abutment portion 148 can be disposed inside the elastic body 147, passing through the sidewall of the first support 141 and abutting against the aerosol-generating article within the first channel 142. For example, the number of abutment portions 148 can be one or more, and they can be as follows: Figure 1 The three shown are abutting portions 148 that can be evenly distributed circumferentially along the elastic body 147.

[0054] In the clamping structure 14 of this embodiment, the clamping member 146 is assembled with the first support 141 by sleeved elastic body 147 on the outside of the first support 141 and abutment portion 148 passing through the side wall of the first support 141. This allows the abutment portion 146 to move different distances away from the first channel 142 by means of the elastic deformation of elastic body 147. In particular, the end of the abutment portion can move to align with the inner wall of the first channel, thus accommodating various types of cigarettes. Furthermore, the clamping of aerosol-generating articles through the sleeved assembly structure reduces the number of assembly parts. For example, when aerosol-generating articles 201 of different diameters are inserted, the abutment portion 148 moves with the outward deformation of the outer elastic body 147, thereby providing a greater range of motion.

[0055] In some embodiments, combined with Figures 1 to 3As shown, the first bracket 141 has at least one bracket through hole 143 on its side wall, and one bracket through hole 143 is used for one abutment 148 to pass through. For example, each bracket through hole 143 can be configured to guide the abutment 148 therein to move radially along the first channel 142. The number and position of the bracket through holes 143 correspond to the abutment 148.

[0056] Furthermore, the bracket through-hole 143 may extend circumferentially along the first bracket 141; that is, the bracket through-hole 143 has an appropriate length in the circumferential direction. Each bracket through-hole 143 may have opposing upper surfaces 143a and lower surfaces 143b. The upper surfaces 143a and lower surfaces 143b may be parallel to each other, or may gradually approach each other as they approach the inner side of the first bracket 141. The bracket through-hole 143 and the abutment portion 148 may be loosely fitted to allow the abutment portion 148 to move freely in the radial direction.

[0057] In some embodiments, combined with Figures 2 to 3 As shown, the first bracket 141 has a protruding portion that protrudes into the first channel 142, and the bracket through hole 143 passes through the protruding portion. The protruding portion may protrude further inward than other parts of the inner side of the first bracket 141, and the protruding portion may be arranged in a ring shape within the first channel 142, with the bracket through hole 143 formed therein; thus, the protruding portion can increase the wall thickness of the portion where the bracket through hole 143 is located, thereby increasing the structural strength.

[0058] Furthermore, the protruding portion may include a groove through which the support through-hole 143 passes. The groove may be an axially formed groove on the protruding portion, or it may be a groove formed around the support through-hole 143. By providing the groove, the structural support in the vertical direction of the end portion of the abutment 148 can be reduced, thereby increasing the cantilever length of the abutment 148 and making the abutment 148, made of elastic material, easier to deform.

[0059] In some embodiments, combined with Figures 2 to 3As shown, the inner side of the first support 141 may include a second inner surface 144b, which is located within a second cylindrical surface having a second diameter. The second inner surface 144b may be the inner surface of the aforementioned protruding portion. Depending on the structural design requirements, the inner side of the first support 141 may also include surface portions of various other shapes, such as a stepped surface portion in the axial direction. The second diameter may be set as the minimum diameter of the inner side of the first support 141. The end of the abutment portion 148 protrudes beyond the second inner surface 144b in the free state. When an aerosol-generating article, such as a cigarette, is inserted, the elastic body 147 can be moved and elastically deformed by the abutment portion 148, and during elastic deformation, the end of the abutment portion 148 is allowed to move radially outward in the first channel 142 to at least align with the second inner surface 144b. Thus, the abutment portion 148 may have a large radial movement range.

[0060] In other embodiments, combined with Figures 2 to 3 As shown, the inner side of the first support 141 includes a first inner surface 144a and a second inner surface 144b, which are connected circumferentially to the first support 141. The first inner surface 144a may be located within a first cylindrical surface having a first diameter, and the second inner surface 144b may be located within a second cylindrical surface having a second diameter, wherein the first diameter is larger than the second diameter. The first inner surface 144a may be the inner surface of the groove of the aforementioned protruding portion. The end of the abutment portion 148 protrudes beyond the first inner surface 144a and radially inward beyond the second inner surface 144b of the first channel 142. Thus, the end of the abutment portion 148 can be used to clamp the aerosol generating article 201, and facilitates insertion and removal of the aerosol generating article from the clamping structure 14.

[0061] Furthermore, the second diameter can be used to define the maximum diameter of the aerosol-generated article.

[0062] In some embodiments, combined with Figure 1 and Figure 3 As shown, the outer side of the first bracket 141 is provided with a bracket groove 145 extending circumferentially along the first bracket 141. The bracket groove 145 accommodates the elastic body 147. In addition, the bracket groove 145 allows the elastic body 147 to move in a direction away from the first channel 142. In this way, while accommodating the elastic body 147, the bracket groove 145 also prevents the elastic body 147 from moving in the axial direction of the first bracket 141, which is equivalent to mounting the elastic body 147 on the first bracket 141 through the bracket groove 145.

[0063] In some embodiments, combined with Figures 1 to 3 As shown, the first support 141 is a hollow cylindrical shape and defines the first channel 142. Additionally, the elastic body 147 may be annular, such as an O-ring. Further, the abutment portion 148 may be made of an elastic or rigid material; for example, the elastic material may be elastic rubber, especially silicone, to clamp an aerosol-generating article, such as a cigarette, through frictional force generated by the flexible deformation of the abutment portion 148; the rigid material may be metal or rigid plastic. Furthermore, the abutment portion 148 may be evenly distributed along the elastic body 147. Additionally, the abutment portion 148 may have a flat shape to increase the contact area and frictional force with the aerosol-generating article.

[0064] In some embodiments, combined with Figures 1 to 3 As shown, the thickness of the abutment portion 148 can gradually decrease radially inward from the first channel 142, and the width of the abutment portion 148 can also gradually decrease radially inward from the first channel 142; the end of the abutment portion 148 can have an arc-shaped surface. These features facilitate the deformation of the abutment portion 148 made of an elastic material. Furthermore, even if the abutment portion 148 is made of a rigid material, it can still possess the aforementioned features.

[0065] In some embodiments, combined with Figure 1 As shown, the elastic body 147 and the abutment portion 148 can be a single-piece molded structure. For example, the clamping component 146 can be injection molded from silicone material in one step. Alternatively, when the abutment portion 148 is made of a rigid material, the clamping component 146 can be manufactured using processes such as overmolding or insert molding. Using a single-piece molded structure simplifies the manufacturing process, and the resulting clamping component 146 can have a better clamping effect.

[0066] In other embodiments, combined with Figure 1As shown, the clamping component 146 is generally annular and includes a first segment 146a and a second segment 146b connected to the first segment 146a. The first segment 146a is fixedly connected to the first support 141, and the second segment 146b abuts against the aerosol-generated product within the first channel 142. The second segment 146b is capable of elastic deformation and can move outward relative to the first segment 146a in the radial direction of the first channel 142. It is readily understood that the first segment 146a may or may not be elastic, while the second segment 146b is configured to be elastically deformable; thus, under the elastic action of the second segment 146b, the first segment 146a can be fixedly mounted on the first support 141. For example, the first segment 146a may be the portion of the aforementioned elastic body 147 located between two adjacent abutment portions 148; the second segment 146b may include the abutment portion 148 and a portion of the elastic body 147 directly connected to it. In some other embodiments, the second segment 146b can elastically deform to move part or all of the first segment 146a outward in the radial direction of the first channel 142.

[0067] Furthermore, there can be multiple first segments 146a and multiple second segments 146b, and these multiple first segments 146a and multiple second segments 146b are alternately arranged in the circumferential direction of the clamping member 146. For example, there can be 3 or 4 first segments 146a and multiple second segments 146b, etc. The first segments 146a and multiple second segments 146b can be evenly arranged in the circumferential direction of the clamping member 146.

[0068] Furthermore, in some cases of its elastic deformation (e.g., when it is close to or at its maximum deformation), the second segment 146b may be further away from the first channel 142 relative to the first segment 146a.

[0069] The clamping structure 14 of these embodiments can be applied to various electronic atomizing devices that require clamping of aerosol-generating products such as cigarettes. Some examples of electronic atomizing devices are described below.

[0070] Please refer to the following: Figures 4 to 6The diagrams show two three-dimensional assembly schematics and a cross-sectional schematic of an electronic atomizing device 100 provided in an embodiment of the present invention. The electronic atomizing device 100 mainly includes a solid-state substrate heating component 10, a housing component 30, and a power supply component 40, and may further include a liquid atomizing component 20. The housing component 30 houses the solid-state substrate heating component 10, the liquid atomizing component 20, and the power supply component 40. The power supply component 40 provides the electrical power required for the operation of the solid-state substrate heating component 10 and the liquid atomizing component 20, and can control the operation of the solid-state substrate heating component 10 and the liquid atomizing component 20.

[0071] The electronic atomizing device 100 defines a heating chamber 111 and includes the aforementioned clamping structure 14. The clamping structure 14 may be disposed within the electronic atomizing device 100, and its first support 141 communicates with the heating chamber 111. Additionally, the electronic atomizing device 100 may define a top insertion port 311, and the clamping structure 14 may be disposed within the electronic atomizing device 100 and located below the top insertion port 311; alternatively, the clamping structure 14 may directly serve as the top insertion port 311 or be disposed within the top insertion port 311.

[0072] In addition, combined Figure 6 and Figure 8 As shown, the heating chamber 111 defined by the electronic atomizing device 100 is used to house the aerosol generating product 201. The heating chamber 111 can be defined by the housing component of the electronic atomizing device 100. The solid matrix heating assembly 10 is used to heat the solid aerosol generating product 201 and generate a first aerosol. The aerosol generating product 201 can also be referred to herein as the solid first matrix, which may be, for example, in the form of a cigarette and has an internal airflow path; since the heating chamber 111 is used to house the aerosol generating product 201, it can also be referred to as a housing chamber. The liquid atomizing assembly 20 is used to atomize the liquid second matrix 202, such as e-liquid or liquid medicine, and generate a second aerosol. The solid matrix heating assembly 10 is located above the liquid atomizing assembly 20. The liquid atomizing component 20 has a first air outlet 213a, and the solid matrix heating component 10 has a first air inlet 152a; the first air outlet 213a and the first air inlet 152a are in direct fluid communication, so that the second aerosol can enter the heating chamber 111 and mix with the first aerosol; and the first air outlet 213a is eccentrically positioned relative to the heating chamber 111.

[0073] It should be noted that when the aerosol generating product 201 and the second matrix 202 atomize the product and have a respiratory therapeutic effect, the electronic atomizing device 100 can be called a respiratory electronic atomizer; when the atomized product of the aerosol generating product 201 and the second matrix 202 is similar to cigarette smoke, the electronic atomizing device 100 can be called an electronic smoking device.

[0074] In the electronic atomizing device 100 of this embodiment, by positioning the solid matrix heating component 10 above the liquid atomizing component 20, and ensuring direct fluid communication between the first air outlet 213a and the first air inlet 152a, and by setting the first air outlet 213a off-center relative to the heating chamber 111, the problem of e-liquid condensate and tobacco residue generated in the airflow channel of the solid matrix heating component 10 falling directly into the airflow channel of the liquid atomizing component 20 can be avoided. Therefore, the electronic atomizing device 100 of this embodiment provides a better vaping experience.

[0075] In some embodiments, combined with Figure 6 As shown, the liquid atomizing component 20 and the heating chamber 111 are also fluidly connected, allowing the second aerosol to enter the heating chamber 111. Correspondingly, when an aerosol generating article 201, such as a cigarette, is placed inside the heating chamber 111, the second aerosol can enter the interior of the aerosol generating article 201 as the user inhales. Furthermore, when there is a gap or flow channel on the outer periphery of the aerosol generating article 201, such as a cigarette, and the heating chamber 111, the second aerosol can also enter such a gap or flow channel.

[0076] In some embodiments, the solid matrix heating assembly 10 may be a center-heating structure, for example, it may include a heating element for insertion into the aerosol generating article 201 and for generating heat to heat the aerosol generating article 201, and may further employ infrared radiation heating. In this case, the space defined within the electronic atomizing device 100 for accommodating the aerosol generating article 201 can be defined as a heating chamber. The heating element may be in the form of a heating plate or a heating needle.

[0077] In some embodiments, combined with Figure 6 , Figure 8 , Figures 17 to 19As shown, the solid matrix heating assembly 10 is in the form of circumferential heating. For example, the solid matrix heating assembly 10 may include a tubular heating element 10a, which may include a heating base 11 and a first end cap 151. The heating base 11 may be hollow, with the heating chamber 111 formed inside. The first end cap 151 defines a second channel 152, which has a first air inlet 152a. The lower end of the heating base 11 is connected to the first end cap 151, and the first end cap 151 and the heating base 11 are in fluid communication. The tubular heating element 10a can bake and heat the aerosol-generating product 201 by electromagnetic heating, resistance heating, infrared heating, etc.

[0078] In a further embodiment, combined with Figure 6 and Figure 8 As shown, when projected along the vertical direction A1, the first orthographic projection of the inner side of the second channel 152 and the second orthographic projection of the first air outlet 213a can overlap by at least 50%, for example, by 60%, 70%, 80%, 90%, 100%, etc. It is easy to understand that the higher this degree of overlap, the more of the inner side of the second channel 152 covers the first air outlet 213a, thereby better preventing impurities from falling directly into the first airflow channel 213 of the liquid atomizing component 20.

[0079] In a further embodiment, combined with Figure 6 and Figure 8 As shown, the cross-sectional area of ​​the second channel 152 gradually decreases in the direction away from the liquid atomizing component 20, and the first air outlet 213a is disposed on the side close to the first air inlet 152a.

[0080] In a further embodiment, combined with Figure 6 , Figure 8 and Figure 21 As shown, the first end cap 151 further defines a mounting groove 153, in which an airflow sensor 44 is disposed, and the airflow sensor 44 is in airflow communication with the second channel 152 through a connecting groove 154. A sealing element may also be provided between the first end cap 151 and the airflow sensor 44 to prevent air leakage through the mounting groove 153. The airflow sensor 44 may be a microphone. In addition, the connecting groove 154 may be disposed adjacent to the first air outlet 213a.

[0081] In some embodiments, combined with Figures 17 to 19As shown, the tubular heating element 10a is configured to bake and heat the aerosol-generating product 201 using infrared heating. The solid substrate heating assembly 10 may further include an infrared electrothermal coating 12, a first electrode 13, and a second electrode 13a. The infrared electrothermal coating 12 is coated on the outer side of the heating substrate 11. The first electrode 13 is located outside the heating substrate 11 and in contact with the infrared electrothermal coating 12, and the second electrode 13a is located outside the heating substrate 11 and in contact with the infrared electrothermal coating 12. At least a portion of the infrared electrothermal coating 12 is located 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 electrical power, thereby generating infrared radiation for radiative heating of the solid aerosol-generating product 201.

[0082] In the electronic atomization device 100 of the above embodiment, since the infrared light generated when the solid matrix heating component 10 is working has strong penetrability, it can penetrate the outer aerosol generating product 201 and enter the interior, resulting in more uniform heating of the aerosol generating product 201. Furthermore, it is easy to understand that since the second aerosol also has a high temperature, when the second aerosol passes through the interior of the aerosol generating product 201, it can also heat and bake the aerosol generating product 201.

[0083] In some embodiments, the infrared electrothermal coating 12 is used to receive electrical power to generate heat, thereby generating infrared rays of a certain wavelength, such as far-infrared rays of 8μm to 15μm. When the wavelength of the infrared rays matches the absorption wavelength of the aerosol generating article 201, the energy of the infrared rays is easily absorbed by the aerosol generating article 201. In this example, the wavelength of the infrared rays is not limited and can be infrared rays of 0.75μm to 1000μm, or more specifically, far-infrared rays of 1.5μm to 400μm.

[0084] The infrared electrothermal coating 12 can be applied by thoroughly mixing far-infrared electrothermal ink, ceramic powder, and inorganic binder, followed by drying and curing for a certain period of time. The thickness of the infrared electrothermal coating can be 30μm-50μm. Alternatively, the infrared electrothermal coating can also be applied by mixing tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride, and anhydrous copper sulfate in a certain proportion; or it can be a silicon carbide ceramic layer, a carbon fiber composite layer, a zirconium-titanium oxide ceramic layer, a zirconium-titanium nitride ceramic layer, or a zirconium-titanium... The coating is one of the following: boride ceramic layer, zirconium-titanium carbide ceramic layer, iron oxide ceramic layer, iron nitride ceramic layer, iron boride ceramic layer, iron carbide ceramic layer, rare earth oxide ceramic layer, rare earth nitride ceramic layer, rare earth boride ceramic layer, rare earth carbide ceramic layer, nickel-cobalt oxide ceramic layer, nickel-cobalt nitride ceramic layer, nickel-cobalt boride ceramic layer, nickel-cobalt carbide ceramic layer, or high-silicon molecular sieve ceramic layer; the infrared electrothermal coating can also be other existing material coatings.

[0085] In some embodiments, combined with Figure 6 , Figure 9 and Figures 13 to 16 As shown, the liquid atomizing assembly 20 includes a liquid reservoir 21, a liquid guiding element 22, and a heating element 23. The liquid reservoir 21 defines a liquid containing space 211 for containing a liquid second matrix 202. The liquid guiding element 22 is in fluid communication with the liquid containing space 211 and is used to absorb the second matrix 202 from the liquid containing space 211. The heating element 23 is disposed adjacent to the liquid guiding element 22 and is used to heat at least a portion of the second matrix 202 absorbed by the liquid guiding element 22 when energized to generate a second aerosol. It should be noted that the proximity of the heating element 23 to the liquid guiding element 22 may include direct contact between the heating element 23 and the liquid guiding element 22, or indirect contact between the heating element and the liquid guiding element; furthermore, the fluid communication between the liquid guiding element 22 and the liquid containing space 211 may be direct or indirect.

[0086] The liquid guiding element 22 can be made of a material with capillary channels or pores, such as fiber cotton, porous ceramic body, glass fiber rope, porous glass ceramic, porous glass, or other hard or rigid capillary structures. The liquid guiding element 22 is in fluid communication with the liquid containing space 211 to absorb the liquid second substrate 202 delivered from the liquid containing space 211 and to deliver the second substrate 202 to the vicinity of the heating element 23.

[0087] In a further embodiment, combined with Figure 9 and Figure 16As shown, the liquid guiding element 22 includes an atomizing surface 221 and a liquid-absorbing surface 222, the liquid-absorbing surface 222 being in fluid communication with the liquid containing space 211. The heating element 23 is disposed on the atomizing surface 221 and is used to heat at least a portion of the second matrix 202 absorbed by the liquid guiding element 22 when energized, generating an aerosol that escapes from the atomizing surface 221 and is released. For example, the heating element 23 can be formed on the atomizing surface 221 of the liquid guiding element 22 by means of mounting, printing, deposition, etc. In some embodiments, the heating element 23 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium. Figure 16 As shown, the heating element 23 has a patterned conductive trajectory, such as a meandering or circuitous path, and may include conductive terminals at both ends; the conductive terminals may be in the form of gaskets, and may have shapes such as square, round, or elliptical. The heating element 23 may also be a heating mesh, heating plate, etc. The atomizing surface 221 of the liquid guiding element 22 may be opposite to the liquid absorbing surface 222; or, the side of the liquid guiding element 22 may also serve as the liquid absorbing surface.

[0088] In some other embodiments, the liquid guiding element 22 may be an oil-absorbing cotton, and the heating element 23 may be a heating wire, thereby generating heat by applying electricity according to the heating principle of resistance wire. The liquid containing space 211 is used to collect e-liquid; the oil-absorbing cotton is used to absorb the e-liquid in the liquid containing space 211 and supply it to the heating wire; the heating wire is attached to the oil-absorbing cotton to heat the e-liquid on the oil-absorbing cotton to generate corresponding e-liquid vapor.

[0089] In some other embodiments, the liquid atomizing component 20 may employ ultrasonic atomization and related structures, or molecular resonance atomization and related structures; these will not be elaborated further here.

[0090] In some embodiments, combined with Figure 6 , Figure 9 and Figures 13 to 16As shown, the liquid storage shell 21 further defines a first mounting space 212 and a first airflow channel 213, and the liquid atomizing assembly 20 also includes a first mounting component 24. The second aerosol generated by the liquid atomizing assembly 20 is transported to the solid matrix heating assembly 10 via the first airflow channel 213. The first mounting component 24 is disposed within the first mounting space 212, and the liquid guiding element 22 is mounted on the first mounting component 24. The liquid containing space 211 is in fluid communication with the liquid guiding element 22 through the liquid channel 241 of the first mounting component 24. The second aerosol generated by the liquid atomizing assembly 20 is transported to the solid matrix heating assembly 10 via the first airflow channel 213. In addition, a second sealing element 26 may be provided between the first mounting component 24 and the liquid storage shell 21 to seal the gap therebetween. A third seal 26a may be provided between the liquid guiding element 22 and the first mounting component 24. The third seal 26a may be located between the support sidewall of the liquid guiding element 22 and the first mounting component 24, and is used to seal and isolate the atomizing surface 221 and the liquid absorbing surface 222. That is, the liquid provided by the liquid receiving space 211 can only enter the liquid guiding element 22 through the liquid absorbing surface 222 and then be transported to the atomizing surface 221. The third seal 26a may be generally cup-shaped, so that the liquid guiding element 22 can be accommodated in the recess of the cup-shaped third seal 26a.

[0091] Furthermore, the first airflow channel 213 may be arranged parallel to the heating chamber 111 and connected to the first air inlet 152a of the solid matrix heating assembly 10 (see...). Figure 8 The first airflow channel 213 is directly connected to the first air inlet 152a of the solid matrix heating component 10. Therefore, the atomized second aerosol can enter the aerosol generating product 201 as air from the solid matrix heating component 10, thereby generating mixed-flavor smoke. For example, both the first airflow channel 213 and the heating chamber 111 can be vertically arranged, and the first airflow channel 213 and the heating chamber 111 are eccentrically arranged. In some other embodiments, the first airflow channel 213 is not limited to being parallel to the heating chamber 111, but can have various shapes such as bends or curves.

[0092] In a further embodiment, combined with Figure 9 , Figure 15 and Figure 16As shown, a one-way valve 246 is connected to the first mounting component 24, which is used to allow air to enter the liquid containing space 211. The one-way valve 246 is opened under the action of a pressure difference; thus, in the assembled electronic atomizing device 100, air can enter the liquid containing space 211 through the one-way valve 246 to avoid a large negative pressure in the liquid containing space 211 due to insufficient liquid, thereby allowing the liquid to be smoothly output from the liquid containing space 211 to the liquid guiding element 22. The one-way valve 246 can be, for example, a duckbill valve or other structure that only allows air to enter the liquid containing space 211 from the outside.

[0093] In some embodiments, combined with Figure 6 , Figure 13 and Figure 15 As shown, the liquid storage shell 21 may also be provided with a slag collection cavity 214 on the side facing the solid matrix heating assembly 10. The slag collection cavity 214 can be installed on the liquid storage shell 21 by a separate component, or it can be directly formed by the liquid storage shell 21. The slag collection cavity 214 is in direct fluid communication with the first air inlet 152a. By providing the slag collection cavity 214, slag, condensate, etc. generated above it can fall into the slag collection cavity 214, thereby preventing them from falling into the first airflow channel 213 of the liquid storage shell 21. In addition, by making the liquid atomizing assembly 20 a replaceable unit, the slag, condensate, etc. collected in the slag collection cavity 214 can be removed when the liquid atomizing assembly 20 is replaced; the slag collection cavity 214 of the replaced liquid atomizing assembly 20 can continue to be used to collect slag, condensate, etc. In addition, as Figure 8 , Figure 13 and Figure 15 As shown, the first air outlet 213a of the first airflow channel 213 is located on one side of the tobacco residue receiving cavity 214; furthermore, the first air outlet 213a can be flush with the opening of the tobacco residue receiving cavity 214, that is, located in the same plane.

[0094] In some embodiments, combined with Figure 6 and Figure 8 As shown, the first airflow channel 213 of the liquid atomizing component 20 has a first air outlet 213a, and the first end cap 151 of the solid matrix heating component 10 has a first air inlet 152a; the first air outlet 213a and the first air inlet 152a are directly in fluid communication, so that the second aerosol can enter the solid matrix heating component 10 and mix with the first aerosol.

[0095] In some embodiments, combined with Figures 6 to 8 as well as Figure 17As shown, the solid substrate heating assembly 10 may further include the first support 141, which defines the first channel 142. The two ends of the heating substrate 11 are respectively sealed to the first support 141 and the first end cap 151. For example, the upper end of the heating substrate 11 may be inserted into the lower end of the first support 141, with a first sealing element 19 disposed therebetween; the lower end of the heating substrate 11 may be inserted outside the upper end of the first end cap 151, with a first sealing ring 17 disposed therebetween. The first end cap 151, the heating substrate 11, and the first support 141 are sequentially connected; that is, gas can flow sequentially through the second channel 152, the heating chamber 111, and the first channel 142.

[0096] In a further embodiment, combined with Figure 6 , Figure 8 and Figure 21 As shown, the second channel 152 also has a second air outlet 152b. Projected along the vertical direction A1, the third orthographic projection of the second air outlet 152b overlaps with the fourth orthographic projection of the tobacco residue receiving cavity 214 by at least 50%, for example, 60%, 70%, 80%, 90%, 100%, etc. It is easy to understand that the greater this overlap, the more the tobacco residue receiving cavity 214 corresponds to the second air outlet 152b, thus better collecting the e-liquid and tobacco residue impurities falling downwards through the second air outlet 152b.

[0097] Furthermore, combined Figure 6 and Figure 8 As shown, the solid matrix heating assembly 10 may have a transition section located at least between the first air inlet 152a and the lower end of the heating chamber 111, defining a second channel 152. The second channel 152 is located at least between the first air outlet 213a and the heating chamber 111, and is used to transport the second aerosol output through the first air outlet 213a to the heating chamber 111. The second channel 152 has a smoothly transitioned inner surface; the heating chamber 111, the second channel 152, and the first airflow channel 213 are directly connected sequentially from top to bottom. By configuring the second channel 152 with a smoothly transitioned inner surface, for example, an inner surface that smoothly transitions from the first air inlet 152a to the heating chamber 111, the second aerosol output through the first airflow channel 213 can be smoothly transported within the second channel 152, thereby entering the aerosol generating article 201. Furthermore, the axial length of the second channel 152 may be greater than the diameter of the heating chamber 111. For example, the length of the second channel 152 in the axial direction can be between 1.1 and 2 times the diameter of the heating chamber 111.

[0098] In a further embodiment, combined with Figure 18 and Figure 19 As shown, the heating 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 includes a coated region 115 and an uncoated region 116 adjacent to the distal end 113. The infrared electrothermal coating 12 is formed within the coated region 115. Both the first electrode 13 and the second electrode 13a include a coupling electrode 131 disposed within the uncoated region 116 and a strip electrode 132 extending from the coupling electrode 131 toward the proximal end 112. The strip electrode 132 of both the first electrode 13 and the second electrode 13a is at least partially located within the coated region 115 to form an electrical connection with the infrared electrothermal coating 12. The uncoated region 116 is disposed adjacent to the distal end 113 of the heating substrate 11. Typically, the axial length of the uncoated region 116 can range from 0.5mm to 7mm, for example, it can be 0.5mm, 0.9mm, 1mm, 1.5mm, 2mm, 3mm, 3.5mm, 4mm, 5mm, 7mm, etc. Combined with Figure 17 As shown, the proximal end 112 can be the end of the heating substrate 11 near the upper end cap 141, that is, the upper end of the heating substrate 11; the distal end 113 is the opposite end, that is, the lower end of the heating substrate 11. In some other cases, the proximal end 112 can also be defined as the lower end of the heating substrate 11; and the distal end 113 is the upper end of the heating substrate 11.

[0099] Furthermore, the width of the strip electrode 132 can be in the range of 0.5 to 7 mm, for example, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 3.5 mm, 4 mm, 6 mm, 7 mm, etc. Further, the strip electrode 132 can have a wider width, for example, more than 1.5 mm. By setting a wider width, the resistance of the tubular heating element 10a can be reduced, increasing the electrode's ability to withstand large currents, avoiding the risk of the electrode wire burning out during heating, and also reducing the resistance of the electrode wire, resulting in a more uniform current distribution in the axial direction and a more uniform heating temperature field. It should be noted that if the width of the strip electrode 132 is too wide, it can easily lead to a reduction in the heating surface area, which may reduce infrared radiation. Therefore, a preferred width range is 2 to 4 mm, which reduces the resistance of the tubular heating element 10a without reducing the heating area.

[0100] The first electrode 13 and the second electrode 13a are both at least partially electrically connected to the infrared electrothermal coating 12, allowing current to flow from one electrode to the other via the infrared electrothermal coating 12. The first electrode 13 and the second electrode 13a have opposite polarities; for example, the first electrode 13 is positive and the second electrode 13a is negative; or, the first electrode 13 is negative and the second electrode 13a is positive. In some examples, the first electrode 13 and the second electrode 13a are conductive coatings, which can be metal coatings or conductive tapes, etc. The metal coatings can include silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or alloys of the above metals. In one example, the first electrode 13 and the second electrode 13a are symmetrically arranged along the central axis of the heating substrate 11.

[0101] In some 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, with the infrared electrothermal coating 12 located between the two conductive coatings. The conductive coating may be made of silver powder coating, and the conductive coating is in contact with the infrared electrothermal coating 12.

[0102] Furthermore, the heating substrate 11 can be cylindrical, prismatic, or other cylindrical in shape. When the heating substrate 11 is cylindrical, the heating chamber 111 is a cylindrical hole penetrating the middle of the heating substrate 11. The inner diameter of the hole can be slightly larger than the outer diameter of the aerosol-formed product, facilitating the placement of the aerosol-formed product within the chamber for heating. The heating substrate 11 can be made of high-temperature resistant and transparent materials such as quartz glass, ceramics, or mica, or it can be made of other materials with high infrared transmittance, such as high-temperature resistant materials with infrared transmittance of over 95%, without specific limitations.

[0103] It is easy to understand that by coating the heating substrate 11 with an infrared electrothermal coating 12, the infrared electrothermal coating 12 emits infrared light after being energized. The infrared light penetrates the heating substrate 11 to radiate and heat the aerosol generating product 201, such as a smoking substance, located inside the heating substrate 11. Since infrared light has strong penetrability, it can penetrate the outer smoking substance and enter the interior, making the heating of the smoking substance more uniform.

[0104] In addition, combined Figure 6 , Figure 12 and Figure 17As shown, the solid substrate heating assembly 10 may further include a temperature sensor 10b, such as an NTC (Negative Temperature Coefficient) temperature sensor, for detecting the real-time temperature of the heated substrate 11 and transmitting the detected real-time temperature to the circuit board 41. The circuit board 41 can adjust the magnitude of the current flowing through the infrared electrothermal coating 12 according to the real-time temperature. The temperature sensor 10b can be connected to the circuit board 41 via a wire 16b.

[0105] In addition, combined Figure 9 , Figure 15 and Figure 16 As shown, the liquid atomizing assembly 20 may further include a second mounting component 27. The second mounting component 27 is disposed within the first mounting space 212 and can be snapped into the liquid storage shell 21 to support and fix the first mounting component 24 and the liquid guiding element 22.

[0106] In some embodiments, combined with Figure 6 and Figures 10 to 12 As shown, the outer casing assembly 30 of the electronic atomizing device 100 may include a housing 31, a removable bottom cover 32, and a sliding cover structure 33. The sliding cover structure 33 can be installed on the top of the housing 31 to open or close the cigarette inlet of the electronic atomizing device 100, i.e., the top inlet 311, by sliding back and forth. The power supply assembly 40 of the electronic atomizing device 100 may include a circuit board 41 and a battery 42. The solid matrix heating assembly 10, the liquid atomizing assembly 20, the circuit board 41, and the battery 42 can all be disposed within the housing 31. The solid matrix heating assembly 10 is located above the liquid atomizing assembly 20, and the circuit board 41 and the battery 42 are located on one side of the solid matrix heating assembly 10 and the liquid atomizing assembly 20. For example, the circuit board 41 and the battery 42 can each be placed vertically and located on the right side of the whole formed by the solid matrix heating component 10 and the liquid atomizing component 20; the circuit board 41 can be located between the whole formed by the solid matrix heating component 10 and the liquid atomizing component 20 and the battery 42, and can be perpendicular to the plane where the solid matrix heating component 10, the liquid atomizing component 20 and the battery 42 are located. This arrangement allows the electronic atomizing device 100 to have a compact structure and reasonable layout, and the overall shape can be roughly a flat cuboid.

[0107] In a further embodiment, combined with Figure 6 , Figure 10 and Figure 11As shown, the housing 31 defines a top inlet 311 and a bottom inlet 312. The top inlet 311 communicates with the heating chamber 111 of the solid matrix heating assembly 10, and is used to insert the solid aerosol generating product 201 into the heating chamber 111 through the top inlet 311. The liquid atomizing assembly 20 is configured to be placed inside the housing 31 through the bottom inlet 312. This configuration allows for convenient insertion of the solid aerosol generating product 201 and the liquid atomizing assembly 20 from two different directions, top and bottom, respectively.

[0108] In addition, combined Figure 10 and Figure 11 As shown, the detachable bottom cover 32 can be connected to the bottom of the housing 31 and holds the liquid atomizing component 20 inside the housing 31. For example, one end of the detachable bottom cover 32 may have a snap-fit ​​structure 323, and the other end may have a magnetic suction component 324; thus, by engaging the snap-fit ​​structure 323 at one end of the detachable bottom cover 32 with a slot, for example, in the housing 31, and magnetically attaching the magnetic suction component 324 at the other end to a magnetic suction component mounted on the housing 31, the detachable bottom cover 32 can be installed at the bottom of the housing 31. In this way, the liquid atomizing component 20 in the form of an atomizing cartridge can be opened and closed for removal and placement; while the aerosol generating product 201, for example, a cigarette stick, is removed and placed from above the electronic atomizing device 100, and the two do not interfere with each other. This makes the layout of the electronic atomizing device 100 simple, convenient, and more ergonomic.

[0109] In a further embodiment, combined with Figure 13 and Figure 16 As shown, the liquid atomizing assembly 20 further includes a first electrode pin 25, which is electrically connected to the heating element 23 of the liquid atomizing assembly 20. There can be two first electrode pins 25, each connected to one of the two electrodes of the heating element 23. Furthermore... Figure 10As shown, the battery 42 can also be electrically connected to the second electrode pin 43. For example, the second electrode pin 43 is mounted on the circuit board 41 and connected to the battery 42 through the circuit board 41. There can be two second electrode pins 43, which are respectively connected to the two electrodes of the battery 42. The removable bottom cover 32 is provided with a conductive conversion element 321. The conductive conversion element 321 can be a conductive strip fixed on the upper side of the removable bottom cover 32, and there can be two of them. When the removable bottom cover 32 holds the liquid atomizing component 20 in the housing 31, the conductive conversion element 321 is in conductive contact with the first electrode pin 25 and the second electrode pin 43. Both the first electrode pin 25 and the second electrode pin 43 can be elastic pin structures to enhance the contact effect with the conductive conversion element 321.

[0110] In some other embodiments, the two electrodes of the heating element 23 in the liquid atomizing assembly 20 can also be directly connected to the circuit board 41 via wires, for example, by soldering wires between the electrodes of the heating element 23 and the circuit board 41. This approach is suitable for products that do not require replacement of the liquid atomizing assembly 20, thereby simplifying the wiring structure and reducing costs.

[0111] In a further embodiment, combined with Figure 5 and Figure 10 As shown, the removable bottom cover 32 is provided with an air inlet 322, and the number of air inlets 322 can be one or more. When the removable bottom cover 32 holds the liquid atomizing component 20 inside the housing 31, the air inlet 322 is in gas communication with the liquid atomizing component 20. That is, by providing the air inlet 322, external air can enter the interior of the electronic atomizing device 100 through the air inlet 322 and flow sequentially through the liquid atomizing component 20, the solid matrix heating component 10, and the top inlet 311. Since the solid matrix heating component 10 and the liquid atomizing component 20 share a single air inlet 322, it ensures that most of the liquid atomized smoke can enter the aerosol generating product 201 of the cigarette, which is heated by the solid matrix heating component 10. This can improve the TPM (Total Particulate Matter) of the mixed smoke and the smoking experience.

[0112] In some embodiments, combined with Figure 1 , Figure 6 and Figure 17 As shown, relative to the top socket 311, the clamping member 146 is positioned closer to the heating base 11 of the tubular heating element 10a. That is, in the axial direction of the first support 141, the clamping member 146 can be positioned at a lower position on the first support 141, thereby enabling more effective clamping of the aerosol generating article 201.

[0113] In some embodiments, combined with Figure 17 and Figures 20 to 22 As shown, the solid matrix heating assembly 10 may further include a detachable first sleeve 156, and the first end cap 151 and the detachable first sleeve 156 form an end cap structure 15. The first end cap 151 is used to connect with the tubular heating element 10a; for example, the lower end of the tubular heating element 10a may be supported by the top surface of the first end cap 151, and a sealing element may be provided therebetween. The detachable first sleeve 156 is fitted onto the first end cap 151, forming a gap between them. The first sleeve 156 is used to clamp the electrode contact spring 16 onto the first end cap 151, and to make the electrode contact spring 16 electrically contact the tubular heating element 10a.

[0114] In the electronic atomizing device 100 of this embodiment, the electrode contact spring 16 can be first installed on the first end cap 151, and then the first sleeve 156 can be sleeved on the first end cap 151, thereby clamping the electrode contact spring 16 between the first sleeve 156 and the first end cap 151. This structure further facilitates first connecting the electrode contact spring 16 and the lead wire 16a to conduct electricity by welding or clamping, and then clamping the electrode contact spring 16 in the end cap structure 15.

[0115] In some embodiments, combined with Figures 20 to 21 As shown, the first end cap 151 may include an insertion end 151a, which is used to insert into the tubular heating element 10a. Further, the insertion end 151a is provided with a first circumferential groove 151b, which is used to receive a first sealing ring 17. Thus, when the lower end of the heating base 11 is inserted outside the insertion end 151a of the first end cap 151, a seal can be achieved through the provided first sealing ring 17, preventing gas leakage through the gap between the insertion end 151a and the heating base 11. Moreover, by providing a first circumferential groove 151b that can receive the first sealing ring 17, the problem of difficult mold implementation can be overcome. In this way, the heating chamber 111 of the heating base 11 can be completely sealed by the circumferential compression of the first sealing ring 17, such as silicone, making the assembly more reliable, simple, and stable, and avoiding sealing problems caused by assembly errors.

[0116] Furthermore, combined Figure 17 and Figure 21As shown, the first end cap 151 further includes an intermediate section 151c, which is connected to the insertion end 151a. The intermediate section 151c is configured to have a cross-sectional dimension larger than that of the insertion end 151a. The intermediate section 151c has a first support surface 151d extending radially outward from the insertion end 151a. The first support surface 151d is used to support the end face of the tubular heating element 10a, that is, the lower end face of the tubular heating element 10a. In addition, the gap between the first sleeve 156 and the intermediate section 151c is used to receive a portion of the electrode contact spring 16, that is, the lower end portion of the electrode contact spring 16. Thus, the lower end portion of the electrode contact spring 16 can be clamped and fixed, while the upper end portion of the electrode contact spring 16 can be used to make conductive contact with the tubular heating element 10a.

[0117] For example Figure 21 and Figure 22 As shown, the outer periphery of the intermediate section 151c is provided with a first protrusion 151e, which is used to stop and cooperate with the first groove 162 in the electrode contact spring 16 to prevent the electrode contact spring 16 from axially disengaging from the intermediate section 151c. Additionally, the outer periphery of the intermediate section 151c may be provided with a first recess 151f, which is used to receive the lead wire connection portion 167 of the electrode contact spring 16. Figure 20 As shown, the lead wire connection portion 167 can be electrically connected to the lead wire 16a by welding or clamping.

[0118] In some embodiments, combined with Figure 17 and Figure 21 As shown, the first end cap 151 also includes a base end 151g opposite to the insertion end 151a. The base end 151g has a second support surface 151h extending radially outward from the first end cap 151. The second support surface 151h is used to support the end face of the first sleeve 156, that is, the lower end face of the first sleeve 156.

[0119] Furthermore, combined Figure 17 and Figure 21 As shown, the base end 151g also has a third support surface 151i extending radially outward from the first end cap 151. The third support surface 151i is used to support the end face of the heat insulation tube 18, i.e., the lower end face. Combined with... Figure 6As shown, the heat insulation tube 18 is disposed within the housing 31 of the outer casing assembly 30 and on the outside of the tubular heating element 10a, and is also connected to the first end cap 151. The heat insulation tube 18 can prevent a large amount of heat from being transferred to the outer casing assembly 30, thus avoiding the user feeling hot to the touch. The heat insulation tube 18 includes heat insulation material, which can be heat insulation adhesive, aerogel, aerogel felt, asbestos, aluminum silicate, calcium silicate, diatomaceous earth, zirconium oxide, etc. The heat insulation tube can also be a vacuum heat insulation tube. An infrared reflective coating can also be formed inside the heat insulation tube 18 to reflect the infrared rays emitted by the infrared electrothermal coating on the heating substrate 11 back to the infrared electrothermal coating 12, thereby improving heating efficiency.

[0120] In addition, combined Figure 20 and Figure 21 As shown, the base end 151g is also provided with a second circumferential groove 151j, which is used to receive the second sealing ring 17a. For example, the lower end of the heat insulation tube 18 can be sleeved on the base end 151g, so that the third support surface 151i supports the end face of the heat insulation tube 18. Thus, the second sealing ring 17a can seal the gap between the heat insulation tube 18 and the base end 151g for better heat insulation.

[0121] Furthermore, the base end 151g may also be provided with a lead wire groove 151k, the lead wire groove 151k being recessed inward from the outer surface of the base end 151g. Combined with Figure 17 and Figure 20 As shown, the lead groove 151k communicates with the first recess 151f and is used to accommodate the connection end of the lead 16a, and to guide the lead 16a to bend outward toward the base end 151g and change direction, so as to connect with the circuit board 41 of the power supply component 40.

[0122] In some embodiments, combined with Figure 17 and Figure 21 As shown, the first end cap 151 is hollow and defines a second channel 152. The second channel 152 is used for airflow communication with the heating chamber 111 and the first channel 142.

[0123] In some embodiments, combined with Figure 22As shown, the electrode contact spring 16 may include a spring body 161 and a lead wire connection portion 167. The spring body 161 is used for conductive contact with an electrode; for example, the spring body 161 of one electrode contact spring 16 may be in conductive contact with a first electrode 13 on the heating substrate 11 of the solid matrix heating assembly 10, and the spring body 161 of another electrode contact spring 16 may be in conductive contact with a second electrode 13a on the heating substrate 11 of the solid matrix heating assembly 10. The lead wire connection portion 167 is connected to the spring body 161, and the lead wire connection portion 167 is configured to clamp a lead wire 16a by deformation.

[0124] In the electronic atomizing device 100 of this embodiment, by configuring the lead wire connector 167 to clamp the lead wire 16a through deformation, one end of the lead wire 16a can be inserted into the groove of the lead wire connector 167 during assembly. Then, a jig is used to press down on the lead wire connector 167 to deform it and fix the lead wire 16a. This assembly method can be processed outside the production line, and it can be used as a single part during assembly and disassembly, avoiding the cumbersome welding process.

[0125] In some embodiments, combined with Figure 22 As shown, the spring body 161 may define two first grooves 162 and has a first connecting strip 163 located between the two first grooves 162, and the lead wire connecting portion 167 is connected to the first connecting strip 163. For example, the first grooves 162 may be punched to form two parts of the lead wire connecting portion 167, and then these two parts may be bent to form a shape as shown. Figure 22 The lead wire connection part 167 is shown.

[0126] In some embodiments, combined with Figure 22 As shown, the lead wire connection portion 167 includes a first bent portion 168 and a second bent portion 168a, which together form a lead wire receiving space.

[0127] Furthermore, the ends of the first bent portion 168 and the second bent portion 168a can be arranged facing each other. Thus, when fixedly connected with the lead wire 16a, the first bent portion 168 and the second bent portion 168a can be flattened, thereby clamping the lead wire 16a within the lead wire receiving space, while simultaneously making contact with the lead wire connection portion 167 for electrical conduction.

[0128] Alternatively, the ends of the first bend 168 and the second bend 168a can be positioned close to each other, with both ends facing the lead wire receiving space. Thus, when fixedly connected to the lead wire 16a, a jig can be used to press down on the first bend 168 and the second bend 168a to deform them, thereby forcing both ends of the first bend 168 and the second bend 168a to press firmly onto the lead wire 16a, thereby more securely fixing the lead wire 16a.

[0129] In some embodiments, combined with Figure 22 As shown, the spring body 161 has an elastic cantilever 164 at one end away from the lead wire connection portion 167, and a conductive contact 164a is formed near the end of the elastic cantilever 164. The number of elastic cantilever 164 can be one or more, and they can be formed by stamping. The conductive contact 164a is used for conductive contact with the electrode. Furthermore, the conductive contact 164a and the lead wire connection portion 167 are located on the same side of the spring body 161. Further, the spring body 161 can be curved in shape to match structures such as the tubular first sleeve 156 and the tubular heating element 10a.
