Description

Technical Field

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

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

[0003] An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol-providing products, such as so-called electronic atomization devices. These electronic atomization devices typically contain a liquid, and the liquid is drawn through a porous ceramic body and heated by a heating element attached to the surface of the porous ceramic body to produce an inhalable aerosol. During use, since the heating element is attached to the surface of the porous ceramic body, the rigid contact between them affects the sufficient wetting of the liquid matrix on the heating element. Furthermore, in Chinese patent CN 202310644262.0, the applicant arranges a flexible capillary element between the rigid porous ceramic body and the heating element to enhance the wetting of the liquid matrix on the heating element. During assembly, the lack of mechanical connection and fixation of multiple parts is not conducive to the overall stable assembly, and gaps are easily formed between the components after assembly. For example, the loose contact between the flexible capillary element and the thin heating element can cause the heating element to burn dry. Utility Model Content

[0056] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0057] One embodiment of the present application provides an electronic atomization device, which can be found in Figure 1 As shown, it includes a nebulizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply body 200 that supplies power to the nebulizer 100. Figure 1In the illustrated embodiment, the atomizer 100 and the power supply body 200 of the electronic atomization device are detachable relative to each other; an electronic atomization device having such an atomizer 100 and a power supply body 200 that are detachable relative to each other is, for example, a so-called "replaceable cartridge" electronic atomization device. Or in some other variations, the atomizer 100 and the power supply body 200 of the electronic atomization device are tightly wrapped and fixed by the outer shell component of the electronic atomization device, so that the atomizer 100 and the power supply body 200 cannot be detachable relative to each other from the inside of the outer shell component. An electronic atomization device having such an atomizer 100 and a power supply body 200 that are not detachable relative to each other is, for example, a so-called "integrated or disposable" electronic atomization device.

[0058] In some embodiments, the power supply body 200 can receive one nebulizer 100 and supply power to the nebulizer 100. Alternatively, in other embodiments, the power supply body 200 can simultaneously receive at least two or more nebulizers 100; and during each use, the power supply body 200 can selectively supply power to one of the at least two or more nebulizers 100 received simultaneously, so that the one nebulizer 100 atomizes the liquid matrix to generate an aerosol.

[0059] In an alternative embodiment, such as Figure 1 As shown, the power supply body 200 includes a receiving cavity 270 for receiving and accommodating at least a portion of the atomizer 100 , and the receiving cavity 270 is disposed at one end along the longitudinal direction.

[0060] according to Figure 1 In the exemplary embodiment shown, the power supply body 200 further includes an electrical contact 230 at least partially exposed on the surface of the receiving cavity 270, for supplying power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply body 200. Figure 1 In the exemplary embodiment shown, the atomizer 100 is provided with an electrical contact 21 , and when at least a portion of the atomizer 100 is received in the receiving cavity 270 , the electrical contact 21 contacts and abuts against the electrical contact 230 to thereby form electrical conduction.

[0061] exist Figure 1 In the embodiment of the present invention, a sealing member 260 is provided in the power supply body 200, and the sealing member 260 separates at least a portion of the internal space of the power supply body 200 to form the above receiving cavity 270. Figure 1 In the exemplary embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply body 200 and is preferably made of a flexible material, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing to the controller 220, sensor 250 and other components inside the power supply body 200.

[0062] exist Figure 1 In the exemplary embodiment shown, the power supply body 200 also includes a battery cell 210 for power supply at the other end away from the receiving cavity 270 in the longitudinal direction; and a controller 220 arranged between the battery cell 210 and the receiving cavity 270, which is operable to guide current between the battery cell 210 and the electrical contact 230.

[0063] During use, the power supply body 200 includes a sensor 250 for sensing the suction airflow generated by the atomizer 100 during inhalation, and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250 .

[0064] exist Figure 1 In the exemplary embodiment shown, the power supply body 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210 .

[0065] Figure 2 Shown Figure 1 A schematic structural diagram of an embodiment of the atomizer 100 includes:

[0066] The proximal end 110 and the distal end 120 are opposite to each other in the longitudinal direction; the proximal end 110 is configured as the end for the user to inhale the aerosol, and an air outlet 111 for the user to inhale is provided at the proximal end 110; and the distal end 120 is used as the end combined with the power supply body 200.

[0067] See also Figure 2 As shown, the nebulizer 100 includes a housing 10 extending between a proximal end 110 and a distal end 120; and the proximal end 110 and the distal end 120 are formed or defined by the housing 10. Figure 2 As shown, the housing 10 is generally in the shape of a longitudinal cylinder. Of course, the interior of the housing 10 is hollow and is a necessary functional component for storing and atomizing the liquid matrix.

[0068] See also Figure 2 As shown, the housing 10 is provided with a liquid storage chamber 12 for storing a liquid matrix, and an atomizing assembly 30 for drawing the liquid matrix from the liquid storage chamber 12 and heating and atomizing the liquid matrix. Figure 2 In the schematic diagram shown, an aerosol transmission tube 11 is provided in the housing 10 along the axial direction. The space between the aerosol transmission tube 11 and the inner wall of the housing 10 forms a liquid storage chamber 12 for storing a liquid matrix. The aerosol transmission tube 11 extends to or terminates at an air outlet 111, thereby transmitting the generated aerosol to the air outlet 111 for inhalation.

[0069] In some optional embodiments, the aerosol transmission tube 11 and the housing 10 are integrally molded using a moldable material, thereby defining a liquid storage chamber 12 between the aerosol transmission tube 11 and the housing 10, and the liquid storage chamber 12 has an opening open toward the distal end 120.

[0070] See also Figure 2 and Figure 3 As shown, the nebulizer 100 further includes an atomizing assembly 30 for atomizing at least a portion of the liquid matrix to generate an aerosol. Figure 2 As shown, the atomizer assembly 30 is housed or held within the flexible sealing base 20. Furthermore, the sealing base 20 substantially surrounds the atomizer assembly 30, and at least a portion of the sealing base 20 is also used to provide a seal between the housing 10 and the atomizer assembly 30. The flexible sealing base 20 is made of a flexible material such as silicone or a thermoplastic elastomer.

[0071] In the embodiment, the atomizer assembly 30 is housed and held in the sealing base 20, and the atomizer assembly 30 is in fluid communication with the liquid storage chamber 12 through the liquid channel 13 defined by the sealing base 20 to receive the liquid matrix. Figure 2 As shown by the arrow R1, the liquid in the liquid storage chamber 12 flows through the liquid channel 13 to the atomizer assembly 30 and is absorbed and heated; the aerosol generated is then output to the air outlet 111 through the aerosol transmission tube 11 and inhaled by the user. Figure 2 As shown by the arrow R2.

[0072] according to Figure 2 As shown, the atomizer assembly 30 is arranged substantially perpendicular to the longitudinal direction of the housing 10. An atomizer chamber 340 is defined between the atomizer assembly 30 and the distal end 120 of the housing 10. The atomizer chamber 340 is located on the side of the atomizer assembly 30 facing away from the liquid storage chamber 12. The atomizer chamber 340 is used to contain the released aerosol. During inhalation, external air enters the atomizer chamber 340 through the air inlet 22 of the distal end 120, carrying the aerosol in the atomizer chamber 340 to the aerosol transmission tube 11, and is then inhaled by the user at the air outlet 111.

[0073] See also Figures 2 to 5 As shown, the specific structure of the atomizing assembly 30 includes:

[0074] The rigid porous body 32 is generally configured in a plate-like or sheet-like shape; and the porous body 32 has a first surface 322 and a second surface 323 that are separated from each other; the first surface 322 is arranged toward the liquid storage chamber 12 and is in fluid communication with the liquid storage chamber 12 through the liquid channel 13 to absorb the liquid matrix;

[0075] The flexible capillary fiber element 33 is generally configured in the shape of a sheet or a thin layer; the flexible capillary fiber element 33 can be laminated and bonded to the second surface 323 of the porous body 32 and can absorb the liquid matrix from the porous body 32;

[0076] The heating element 40 is arranged as a substantially planar heating element; and the heating element 40 includes a first electrode portion 41 and a second electrode portion 42 facing each other in a longitudinal direction, and a heating portion 43 extending between the first electrode portion 41 and the second electrode portion 42;

[0077] The heating portion 43 is coupled to the side of the capillary fiber element 33 facing away from the porous body 32 and is used to heat the liquid matrix to generate an aerosol. The first electrode portion 41 and the second electrode portion 42 are used to conduct current to the heating portion 43. After assembly, the electrical contact 21 extends from the distal end 120 into the atomizer 100 and abuts against the first electrode portion 41 and the second electrode portion 42, thereby powering the heating element 40.

[0078] After assembly, the flexible capillary fiber element 33 is clamped between the heating element 40 and the second surface 323 of the porous body 32. Furthermore, the clamped flexible capillary fiber element 33 is at least partially compressed or squeezed, which is beneficial for liquid locking.

[0079] In some embodiments, the capillary fiber element 33 and / or the heating element 40 are sheet-like, meaning that their thickness may be substantially smaller than their length and width, and they are essentially configured as sheets.

[0080] In yet other variations, the porous body 32 may have other regular or irregular shapes, such as an arched shape. In some embodiments, the first surface 322 and / or the second surface 323 of the porous body 32 are flat, extended planes; or in yet other variations, the first surface 322 and the second surface 323 are curved surfaces, such as concave or convex surfaces.

[0081] In some embodiments, the rigid porous body 32 includes a plurality of liquid-conducting channels 321 arranged on a dense matrix material; the plurality of liquid-conducting channels 321 extend straight along the thickness of the porous body 32. Furthermore, the liquid-conducting channels 321 penetrate the porous body 32 along its thickness. The liquid-conducting channels 321 penetrate or extend from a first surface 322 to a second surface 323. During use, liquid substrate is transferred from the first surface 322 to the second surface 323 by capillary infiltration of the liquid-conducting channels 321 and absorbed by the capillary fiber elements 33. Furthermore, in some embodiments, the plurality of liquid-conducting channels 321 are arranged in an orderly manner within the porous body 32. The plurality of liquid-conducting channels 321 extend in a predetermined direction, rather than in a random manner. Furthermore, in some embodiments, the plurality of liquid-conducting channels 321 are arranged in an array within the porous body 32. Furthermore, in some embodiments, the plurality of liquid-conducting channels 321 can transfer liquid substrate from the first surface 322 to the second surface 323 at a predetermined rate.

[0082] In some embodiments, the diameter of the liquid-conducting channel 321 is between 15 μm and 60 μm. In some embodiments, the spacing between adjacent liquid-conducting channels 32 is between 5 μm and 40 μm.

[0083] In some embodiments, the porous body 32 is fabricated by forming a plurality of liquid-conducting channels 321 in a dense matrix material by laser pore formation, mechanical drilling, or etching. In some embodiments, the dense matrix material may be made of, for example, at least one of dense glass, ceramic, carbon, metal, or a high-temperature-resistant polymer plastic. The high-temperature-resistant polymer plastic may include at least one of polyamide, polysulfone, polyphenylene sulfide, polyetherimide, polyimide, polyaryletherketone, polyarylate, polysulfone, liquid crystal polymer, polytetrafluoroethylene, and polyvinylidene fluoride. Furthermore, in some embodiments, the dense matrix material may be produced by methods such as hot die casting, dry pressing, tape casting, or chemical synthesis.

[0084] In some embodiments, the porous body 32 has a thickness of 0.1 mm to 3 mm; more preferably, the porous body 32 has a thickness of 0.2 mm to 2 mm. Furthermore, the porous body 32 has a length of 8 to 12 mm and a width of approximately 2.5 to 4 mm. In some embodiments, the arrangement of the plurality of liquid-conducting channels 321 within the porous body 32 gives the porous body 32 a honeycomb structure. In some embodiments, the diameter of the liquid-conducting channels 321 ranges from 0.002 to 0.5 mm.

[0085] Alternatively, in some alternative embodiments, the porous body 32 includes conventional porous materials, such as rigid foam metal, porous ceramics, porous glass, etc., which are formed by mixing the raw materials of the matrix with a pore-forming agent and then sintering; and a large number of disordered micropores arranged inside the porous body 32 defined by sintering of the pore-forming agent absorb and transfer the liquid matrix.

[0086] Alternatively, in some other variations, the porous body 32 includes further mechanical drilling or laser punching on a porous material having a plurality of disordered micropores inside to form a plurality of ordered liquid-conducting channels 321; the porous body 32 includes both a plurality of orderly arranged liquid-conducting channels 321 and a plurality of disorderedly arranged micropores inside.

[0087] In some embodiments, the flexible capillary fiber element 33 comprises at least one of cotton fiber, cellulose fiber, hemp fiber, Tencel fiber, and chemical synthetic fiber, such as a non-woven fabric made from viscose fiber. Preferably, the capillary fiber element 33 comprises natural fiber rather than synthetic fiber. As a suitable example, the sheet-like capillary fiber element 33 has a thickness of approximately 0.5 to 2 mm.

[0088] In some embodiments, the heating element 40 is made of a resistive material, such as a metal material, metal alloy, graphite, carbon, conductive ceramic, or other ceramic and metal composite material with appropriate resistance. Suitable metal or alloy materials include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium alloys, iron-chromium-aluminum alloys, iron-manganese-aluminum alloys, or stainless steel. Furthermore, in some embodiments, the heating element 40 is made from a sheet-like precursor by etching, stamping, or cutting to remove excess portions. Furthermore, the metal or alloy heating element 40 has a thickness of approximately 0.05 to 0.5 mm.

[0089] according to Figure 3 and Figure 4 As shown, the length of the flexible capillary fiber element 33 is slightly larger than the length of the porous body 32. For example, in some embodiments, the flexible capillary fiber element 33 has a length of approximately 6 to 10 mm. After assembly, the flexible capillary fiber element 33 substantially completely covers the second surface 323 of the porous body 32, thereby absorbing the liquid matrix from the liquid conducting channel 321. Furthermore, the flexible capillary fiber element 33 covers the entirety of the liquid conducting channel 321 on the second surface 323. In embodiments, the porous body 32 is formed by punching holes in a dense matrix material to form the liquid conducting channel 321. In this case, the capillary fiber element 33 absorbs the liquid matrix only through the liquid conducting channel 321. Alternatively, in further variations, the porous body 32 is formed by punching holes in a foam matrix material having micropores to form the liquid conducting channel 321. Areas outside the liquid conducting channel 321 can still conduct the liquid matrix through the micropores, and the capillary fiber element 33 can also absorb the liquid matrix through portions outside the liquid conducting channel 321.

[0090] according to Figure 3 and Figure 4As shown, the length of the heating element 40 is greater than the length of the flexible capillary fiber element 33. For example, in some specific embodiments, the length of the heating element 40 is approximately 7 to 12 mm. Therefore, after assembly, the heating element 40 extends across the length of the flexible capillary fiber element 33 along the atomizer assembly 30.

[0091] according to Figure 3 and Figure 4 As shown, the heating portion 43 of the heating element 40 is fluid permeable; as used herein, "fluid permeable" means that an aerosol in the gas phase can easily pass through the heating portion 43. For example, in Figure 4 As shown in FIG, the heating portion 43 is a tortuous shape so as to define a hollow, thereby allowing fluid to permeate. Figure 3 and Figure 4 In the embodiment, the first electrode portion 41 and the second electrode portion 42 are dense.

[0092] according to Figures 2 to 5 As shown, the atomizing assembly 30 further includes:

[0093] The holding element 31 is used to hold and fix the porous body 32, the capillary fiber element 33 and the heating element 40. The holding element 31 holds and fixes the porous body 32, the capillary fiber element 33 and the heating element 40 so that they can be tightly mounted and combined without loosening or creating gaps, which is beneficial for the convenience of batch production and improving the yield rate. In some embodiments, the holding element 31 is rigid. In some embodiments, the holding element 31 is dense. In some embodiments, the holding element 31 is electrically insulating. In some embodiments, the holding element 31 is made of glass, ceramic, surface-insulated metal, or an organic polymer that can withstand temperatures of at least 350°C.

[0094] according to Figures 2 to 5 As shown, the holding element 31 is basically constructed in the shape of a frame. The porous body 32 and the capillary fiber element 33 are accommodated and held in the holding element 31. After assembly, the atomizer 100 / electronic atomization device is combined with the holding element 31, thereby providing support for the porous body 32, the capillary fiber element 33 and the heating element 40. Specifically, the holding element 31 includes:

[0095] A first side 311 and a second side 312 are opposite to each other; the first side 311 faces the liquid storage chamber 12;

[0096] The accommodating cavity 313 extends from the first side 311 to the second side 312 . The accommodating cavity 313 has a section 314 with an increased cross-sectional area on the second side 312 . The section 314 with an increased cross-sectional area defines a step 315 in the accommodating cavity 313 .

[0097] After assembly, the porous body 32 is firmly installed and retained in the accommodating cavity 313; the porous body 32 and the inner surface of the accommodating cavity 313 of the retaining element 31 are connected by laser welding, ultrasonic welding, etc., so that the porous body 32 and the retaining element 31 are firmly connected or combined.

[0098] In some embodiments, for example Figure 3 As shown in FIG, the first surface 322 of the porous body 32 is flush with the surface of the first side 311, which is advantageous for positioning during assembly. Alternatively, in some other embodiments, the first surface 322 of the porous body 32 is recessed relative to the surface of the first side 311. The second surface 323 of the porous body 32 slightly extends into or protrudes from the section 314 with increased cross-sectional area, which is advantageous for providing close contact and abutment for the capillary fiber element 33. For example, the second surface 323 of the porous body 32 can have a protrusion height of 0.2 to 1.0 mm relative to the step 315, or the porous body 32 can extend 0.2 to 1.0 mm into the section 314 with increased cross-sectional area.

[0099] After assembly, the capillary fiber element 33 is accommodated and installed in the section 314 with increased cross-sectional area and is closely attached to the second surface 323 of the porous body 32. After assembly, the capillary fiber element 33 may slightly protrude from the surface of the second side 312. The heating element 40 is firmly bonded to the surface of the second side 312 of the retaining element 31 and squeezes or clamps the capillary fiber element 33. As a result, the capillary fiber element 33 is in good contact or fit with the heating element 40 and / or the porous body 32 without any gaps.
