Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and a porous element. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning a material. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing articles, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol; the liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices produce an aerosol by drawing in and delivering a liquid matrix through a multilayered, parallel, cross-linked network of channels formed within a ceramic matrix, and by heating the liquid matrix delivered through the multilayered, parallel, cross-linked network of channels by a heating element bonded to the ceramic matrix.

[0087] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0088] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100. Figure 1 In the illustrated embodiment, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are separable or detachable relative to each other; an electronic atomizing device having such a separable or detachable atomizer 100 and power supply mechanism 200 is, for example, a so-called "refillable" electronic atomizing device. Alternatively, in some further variations, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are securely enclosed and fixed by the housing components of the electronic atomizing device, thereby preventing the atomizer 100 and power supply mechanism 200 from being detachable relative to each other; an electronic atomizing device having such a non-detachable atomizer 100 and power supply mechanism 200 relative to each other is, for example, a so-called "integrated or disposable" electronic atomizing device.

[0089] In an alternative embodiment, for example Figure 1 As shown, the power supply mechanism 200 includes a receiving cavity 270 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and 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 within the power supply mechanism 200.

[0090] according to Figure 1In the exemplary embodiment shown, an electrical contact 21 is provided at one end of the atomizer 100 along the length direction, so that when at least a portion of the atomizer 100 is received in the receiving cavity 270, the electrical contact 21 forms an electrical conductivity by contacting and abutting against the electrical contact 230.

[0091] exist Figure 1 In the exemplary embodiment shown, a sealing member 260 is provided inside the power supply mechanism 200, and the sealing member 260 divides at least a portion of the internal space of the power supply mechanism 200 to form the 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 mechanism 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 into components such as the controller 220 and sensor 250 inside the power supply mechanism 200.

[0092] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 further includes a battery cell 210 for power supply located at the other end of the receiving cavity 270 along the length direction; and a controller 220 disposed between the battery cell 210 and the receiving cavity 270, the controller 220 being operable to guide current between the battery cell 210 and the electrical contact 230.

[0093] In use, the power supply mechanism 200 includes a sensor 250 for sensing the suction airflow generated when the atomizer 100 is inhaled, 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.

[0094] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210.

[0095] Figure 2 It shows Figure 1 A schematic diagram of one embodiment of the atomizer 100 includes:

[0096] The housing 10 defines at least a portion of the outer surface of the atomizer 100. According to Figure 2 As shown, the outer casing 10 is generally longitudinally elongated cylindrical in shape, with a hollow interior for accommodating essential functional components for storing and atomizing the liquid matrix; the outer casing 10 has a proximal end 110 and a distal end 120 that are opposite to each other along its length. The proximal end 110 is configured as the end where the user inhales the aerosol, and has an outlet 111 for the user to inhale; while the distal end 120 is configured as the end that is connected to the power supply mechanism 200.

[0097] See Figure 2As shown, the housing 10 has a liquid storage chamber 12 for storing a liquid matrix, and an atomizing assembly for drawing the liquid matrix from the liquid storage chamber 12 and heating and atomizing the liquid matrix. Among these, in... Figure 2 In the schematic diagram shown, the outer shell 10 is provided with an aerosol transmission tube 11 arranged along the axial direction. The space between the aerosol transmission tube 11 and the inner wall of the outer shell 10 forms a liquid storage chamber 12 for storing liquid matrix. The aerosol transmission tube 11 extends to or terminates at the air outlet 111, thereby transmitting the generated aerosol to the air outlet 111 for inhalation.

[0098] In some alternative embodiments, the aerosol delivery tube 11 and the housing 10 are integrally molded from a moldable material, thereby defining a liquid reservoir 12 between the aerosol delivery tube 11 and the housing 10, and the liquid reservoir 12 has an opening that opens toward the distal end 120.

[0099] See Figures 2 to 3 As shown, the atomizer 100 further includes an atomizing component for drawing and atomizing the liquid matrix from the liquid reservoir 12 to generate an aerosol; specifically, the atomizing component includes:

[0100] The rigid porous element 30 is generally configured to be plate-shaped, sheet-shaped, or block-shaped; and the porous element 30 has a first side 310 and a second side 320 facing away from each other; the first side 310 is arranged toward the liquid storage cavity 12 and is in fluid communication with the liquid storage cavity 12.

[0101] Heating element 40, attached to the surface of the second side 320 of porous element 30, is used to heat at least a portion of the liquid matrix transferred by porous element 30 to generate an aerosol.

[0102] See Figure 2 In the embodiment shown, the atomizer 100 further includes:

[0103] The rigid support 20 is made of, for example, organic polymer plastic or ceramic; the support 20 is used to house and support the atomizing assembly, especially to house the porous element 30;

[0104] The sealing element 50 is made of a flexible material, such as silicone or a thermoplastic elastomer; the sealing element 50 is at least partially located within the support 20 and partially surrounds or encloses the porous element 30; the sealing element 50 is used to provide a seal between the support 20 and the porous element 30.

[0105] See Figures 2 to 3As shown, the porous element 30 is configured to extend longitudinally perpendicular to the atomizer 100; the first side 310 and the second side 320 of the porous element 30 are arranged opposite to each other along the longitudinal direction of the atomizer 100. The first side 310 of the porous element 30 is arranged towards the liquid reservoir 12 and is in fluid communication with the liquid reservoir 12, for example in... Figure 2 The first side 310, indicated by the middle arrow R1, is in fluid communication with the liquid storage chamber 12 through the liquid transfer channel 13 defined within the support 20 to receive the liquid matrix; the surface of the second side 320 of the porous element 30 is configured as an atomizing surface, and the heating element 40 is attached to the atomizing surface / the surface of the second side 320 of the porous element 30.

[0106] according to Figure 2 As shown, an atomizing chamber 340 is defined between the second side 320 of the porous element 30 and the distal end 120 of the housing 10. This atomizing chamber 340 is located on the side of the porous element 30 opposite to the liquid reservoir 12; the atomizing chamber 340 provides space for releasing aerosol from the atomizing surface of the porous element 30. At least a portion of the heating element 40 is exposed in the atomizing chamber 340. During suction, external air enters the atomizing chamber 340 through the air inlet 22 of the distal end 120, carrying the aerosol within the atomizing chamber 340 to the aerosol delivery tube 11, and is then drawn in by the user at the air outlet 111. Figure 2 As indicated by the middle arrow R2.

[0107] Alternatively, in some variations, the atomizer 100 includes a transverse direction perpendicular to the longitudinal direction; for example, the transverse direction can be either the width direction or the thickness direction of the atomizer 100. Alternatively, for a cylindrical or similar polygonal atomizer 100, the transverse direction can be radial. In an embodiment, the porous element 30 is configured to extend longitudinally along the atomizer 100; the first side 310 and the second side 320 of the porous element 30 are arranged opposite to each other along the transverse direction of the atomizer 100. Thus, the surfaces of the first side 310 and / or the second side 320 of the porous element 30 both extend longitudinally along the atomizer 100; for example, a so-called "side-atomizing" atomizing assembly.

[0108] In some embodiments, the porous element 30 is a flat sheet or plate; and the surface of the first side 310 and / or the surface / atomizing surface of the second side 320 are flat, extended planes. Alternatively, in some other variations, the porous element 30 is a curved, arcuate sheet; and the surface of the first side 310 and / or the surface / atomizing surface of the second side 320 are curved surfaces.

[0109] exist Figures 2 to 3In this embodiment, the porous element 30 is square in shape; or in some other variations, the porous element 30 may be generally circular, elliptical, polygonal, or other shapes with side notches. The porous element 30 may include at least one of glass, ceramic, carbon, metal, and high-temperature resistant polymer plastics.

[0110] In some embodiments, the heating element 40 is a sheet-like heating element that is cut or etched from a sheet substrate and then mounted on the second side 320. In some embodiments, the heating element 40 may be made of a sheet of resistive metal or alloy. In some embodiments, the heating element 40 may include at least one sheet of stainless steel, iron-chromium-aluminum, nickel-chromium alloy, titanium alloy, etc. In embodiments, the sheet-like heating element 40 may be bonded to the porous element 30 by means of glass enamel bonding or surface mounting.

[0111] In some embodiments, the heating element 40 is formed on the second side 320 of the porous element 30 by printing, deposition, spraying, or other methods, thereby achieving close bonding with the porous element 30. Alternatively, in other variations, the heating element 40 includes a thin layer or conductive trace formed on the second side 320 by printing, deposition, or other methods. Specifically, the heating element 40 includes printed, meandering, or meandering conductive traces. In some embodiments, the coating-type heating element 40 may be prepared from one or more of gold, platinum, tantalum, zirconium, niobium, molybdenum, tungsten, tantalum nitride, tungsten carbide, titanium nitride, stainless steel, gold-silver alloys, TiAlN alloys, silver-palladium alloys, nickel-based alloys, nickel-chromium alloys, etc. In some embodiments, the thickness of the coating-type heating element 40 is 0.5–5 μm.

[0112] In some embodiments, a transition layer is further provided between the heating element 40 and the surface of the second side 320 of the porous element 30. The transition layer is advantageous for reducing or suppressing deformation of the heating element 40 caused by thermal cycling during use and for providing stress compensation, thus preventing the heating element 40 from loosening.

[0113] In some embodiments, the transition layer comprises one or more of Ti, Cr, Ni, Mo, Ta, and their oxides or alloys. The coefficient of thermal expansion of the transition layer material is preferably between that of the porous element 30 and the heating element 40; this is advantageous for providing stress compensation and reducing thermal deformation and shedding of the heating element 40. In some embodiments, the thickness of the transition layer is 50–200 μm; in some embodiments, the transition layer is formed between the heating element 40 and the surface of the second side 320 of the porous element 30 by vapor deposition or thermal spraying.

[0114] Alternatively, in some other embodiments, a protective layer may be deposited, sprayed, or covered on the surface of the heating element 40; the protective layer may include one or more of gold, platinum, titanium nitride, tantalum nitride, tungsten carbide, titanium aluminum nitride, chromium aluminum nitride, silicon oxide, silicon nitride, silicon nitride, and stainless steel.

[0115] according to Figure 2 , Figure 27 and Figure 28 As shown, the heating element 40 includes:

[0116] A first electrode portion 41 and a second electrode portion 42 are arranged at intervals along the length direction, and a heating portion 43 extends between the first electrode portion 41 and the second electrode portion 42. The heating portion 43 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 guide current on the heating portion 43. After assembly, an 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 to supply power to the heating element 40.

[0117] exist Figure 27 and Figure 28 In the illustrated embodiment, the first electrode portion 41 and the second electrode portion 42 define the electrical connection region of the heating element 40. Additionally, the heating portion 43 defines the resistance heating region of the heating element 40.

[0118] In some embodiments, electrodes are further arranged on the first electrode portion 41 and / or the second electrode portion 42. For example, the first electrode is arranged by welding, mounting, or sintering after applying silver paste to the first electrode portion 41, and the second electrode is arranged by welding, mounting, or sintering after applying silver paste to the second electrode portion 42. The material of the electrodes may include metals or alloys with low resistivity such as gold, silver, and copper.

[0119] Alternatively, in some other embodiments, the first electrode portion 41 and / or the second electrode portion 42 are connected to the circuit / power supply mechanism 200 by welding conductive leads or the like, so as to enable the controller 220 / power supply mechanism 200 to provide power to the heating element 40.

[0120] In some embodiments, the heating element 40 is fluid-permeable; as used herein, "fluid-permeable" means that aerosols in the gas phase can easily pass through the heating element 40. For example, in Figure 3 As shown, the heating element 40 formed or incorporated on the surface / atomizing surface of the second side 320 of the porous element 30 can be in a mesh shape with pores 431, thereby creating a fluid-permeable environment. For example, in Figure 27In the illustrated embodiment, the heating portion 43 is a mesh shape with openings 431, through which aerosols can pass through the heating portion 43 and / or the heating element 40, thereby making the heating portion 43 and / or the heating element 40 fluid-permeable. Alternatively, in... Figure 28 In the illustrated embodiment, the heating portion 43 is arranged to meander or meander along the length of the heating element 40. Several slits or gaps are formed on the heating portion 43, through which aerosol can pass through the heating portion 43 and / or the heating element 40, thereby making the heating portion 43 and / or the heating element 40 fluid-permeable.

[0121] according to Figures 2 to 7 As shown, the basic sheet-like or block-like porous element 30 may have a first direction, a second direction, and a third direction; any two of the first direction, the second direction, and the third direction are perpendicular to each other. For example, in Figure 3 and Figure 4 As shown, the first direction can be the length direction of the porous element 30, the second direction can be the width direction of the porous element 30, and the third direction can be the height direction of the porous element 30. Figures 2 to 5 In the embodiment shown, the first side 310 and the second side 320 of the porous element 30 may be arranged opposite each other along a third direction.

[0122] exist Figures 3 to 5 As shown, the length of the porous element 30 may be greater than its width, and the width may be greater than its height. In some embodiments, the length of the porous element 30 is approximately between 6 and 15 mm; the width of the porous element 30 is approximately between 3 and 6 mm; and the thickness of the porous element 30 is approximately between 0.8 and 3 mm.

[0123] exist Figures 3 to 7 As shown, the porous element 30 may include:

[0124] At least two or more liquid-conducting layers are stacked for absorbing and transferring a liquid matrix. The at least two or more liquid-conducting layers are stacked along a third direction.

[0156] Alternatively, in some other embodiments, the surface of the liquid-conducting layer in the porous element 30 facing the second side 320 is a rough surface with a liquid-retaining groove.

Specifically, the liquid matrix can only be transferred within the porous element 30 along a first direction, a second direction, and a third direction. Furthermore, the porous element 30 does not contain disordered capillary pores, such as those formed by sintering a pore-forming agent.

[0158] For example Figure 8 and Figure 9In another embodiment shown, the first liquid-conducting layer 31a of the porous element 30a has cross-linked mesh-like liquid-retaining grooves on a surface 314a facing away from the first side 310a; the liquid-retaining grooves may include a first liquid-retaining groove 315a extending in a first direction and a second liquid-retaining groove 316a extending in a second direction. Similarly, at least one third liquid-conducting layer 33a has liquid-retaining grooves arranged on a surface facing the second side 320a; the liquid-retaining grooves may be a first liquid-retaining groove extending in a first direction and a second liquid-retaining groove 336a extending in a second direction.

[0159] or Figures 10 to 12 A schematic diagram of a porous element 30b according to another embodiment is shown; in this porous element 30b, the cross-linked network of liquid storage channels between two adjacent liquid guiding layers can be defined by a first liquid storage groove on the surface of one liquid guiding layer and a second liquid storage groove on the surface of the other liquid guiding layer. Specifically, for example in Figures 10 to 12 In the illustrated embodiment, a plurality of second liquid storage grooves 316b extending in a second direction are arranged on the surface 314b of the first liquid guiding layer 31b facing away from the first side 310b; a plurality of first liquid storage grooves 331b extending in a first direction are arranged on the surface of the third liquid guiding layer 33b facing the first side 310b; and the first liquid storage grooves 331b on the surface of the third liquid guiding layer 33b and the second liquid storage grooves 316b on the surface 314b of the first liquid guiding layer 31b together define the liquid storage channel between the adjacent first liquid guiding layer 31b and the third liquid guiding layer 33b.

[0161] Alternatively, in some other embodiments, one surface of at least one liquid-conducting layer of the porous element 30 has a square liquid-retention groove, and a liquid-conducting hole extends from the liquid-retention groove to the opposite surface; thus, within the porous element 30, the liquid-retention groove can provide a liquid-retention channel between another liquid-conducting layer adjacent to the liquid-conducting layer. For example Figure 13 A schematic diagram of a third liquid-guiding layer 33c with a liquid-retaining groove 331c on its surface is shown in another embodiment. The liquid-retaining groove 331c is square, rather than a cross-linked mesh. The ports of the third liquid-guiding holes 333c are all located within the liquid-retaining groove 331c. Thus, within the porous element 30, the liquid-retaining groove 331c can provide a liquid-retaining channel between the liquid-guiding layers adjacent to the third liquid-guiding layer 33c.

[0162] Alternatively, in some other embodiments, at least one liquid-conducting layer of the porous element 30 is in the shape of a frame.
