Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an atomizer and electronic atomization device. 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 materials. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid matrix that is heated to vaporize, thereby producing an inhalable aerosol. The liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices include a reservoir for storing the liquid matrix and an atomizing component for atomizing the liquid matrix to generate an aerosol; and the electronic atomizing device is also arranged with a ventilation channel communicating the reservoir with external air to regulate the pressure in the reservoir; the ventilation channel is typically located near the liquid outlet of the reservoir, where air entering the reservoir through the ventilation channel during use can easily form bubbles that block the liquid outlet.

[0073] 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.

[0074] 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 1In the illustrated embodiment, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are detachable from each other; electronic atomizing devices with such detachable atomizer 100 and power supply mechanism 200 are, for example, so-called "refillable" electronic atomizing devices. Alternatively, in some further variations, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are securely enclosed and fixed by a housing component of the electronic atomizing device, thereby preventing the atomizer 100 and power supply mechanism 200 from being detachable from each other within the housing component. Electronic atomizing devices with such non-detachable atomizer 100 and power supply mechanism 200 are, for example, so-called "integrated or disposable" electronic atomizing devices.

[0075] See Figure 1 The electronic atomizing device shown includes an atomizer 100 that stores a liquid matrix and heats and vaporizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100.

[0076] In an alternative implementation, such as Figure 1 As shown, the atomizer 100 and the power supply mechanism 200 are removably coupled to each other; and when coupled, the power supply mechanism 200 can be used to supply power to the atomizer 100, thereby causing the atomizer 100 to vaporize the liquid matrix and generate an aerosol. Specifically, the atomizer 100 is removably coupled to the power supply mechanism 200 including one end along its length; the power supply mechanism 200 includes an electrode contact 230; the electrode contact 230 is used to form an electrical connection with the atomizer 100 when the atomizer 100 is coupled to the power supply mechanism 200, thereby supplying power to the atomizer 100.

[0077] according to Figure 1 In one embodiment, the atomizer 100 is at least partially protruding, and in connection with the power supply mechanism 200, the protruding portion of the atomizer 100 extends into the power supply mechanism 200, thereby forming a detachable connection.

[0078] A seal 260 is provided within the power supply mechanism 200 to provide a seal when the atomizer 100 is engaged with the power supply mechanism 200. Figure 1 In the preferred 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 such as silicone, thereby preventing the liquid matrix that seeps out of the atomizer 100 from flowing into components such as the circuit board 220 and the airflow sensor 250 inside the power supply mechanism 200.

[0079] exist Figure 1In the illustrated embodiment, the power supply mechanism 200 further includes a battery cell 210 for power supply; and a circuit board 220 disposed between the battery cell 210 and the electrode contact 230, the circuit board 220 being operable to guide current between the battery cell 210 and the electrode contact 230.

[0080] The power supply mechanism 200 includes an airflow sensor 250, such as a microphone or air pressure sensor, for sensing the airflow generated when the user inhales into the atomizer 100. Then, the circuit board 220 controls the battery cell 210 to output power to the atomizer 100 based on the detection signal from the airflow sensor 250.

[0081] exist Figure 1 In the preferred embodiment shown, the power supply mechanism 200 is provided with a charging interface 240 at the other end away from the atomizer 100 for charging the battery cell 210.

[0082] Figures 2 to 5 The embodiments are shown Figure 1 A schematic diagram of one embodiment of the atomizer 100 shows several components within an outer body or housing 10 (which may be referred to as a shell). The overall design of the outer body or housing 10 is variable, and the type or configuration of the outer body that defines the overall size and shape of the atomizer 100 can vary. Typically, the elongated body may be formed from a single, integral shell, or the elongated shell may be formed from two or more separable bodies. In some examples, the outer body or housing 10 may be formed from a metal or alloy such as stainless steel or aluminum. Other suitable materials include various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, etc. Furthermore, the outer body or housing 10 is generally cylindrical. Alternatively, in some other embodiments, the outer body or housing 10 may have a generally cylindrical shape, or a generally elliptical cylindrical shape, or a generally flattened cylindrical shape with a length greater than its width greater than its thickness, or other regular or irregular shapes.

[0083] See Figures 2 to 7 As shown, the atomizer 100 has a proximal end 110 and a distal end 120 that are opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end closest to the user's inhalation, and the distal end 120 is the end used to connect to the power supply mechanism 200. The outer body or shell 10 of the atomizer 100 is defined by a number of components, specifically including: a first housing 11 that is close to and defines the proximal end 110, a first electrode 21 that is close to and defines the distal end 120, and a generally tubular second housing 12 and a third housing 13 that extend longitudinally between the first housing 11 and the first electrode 21. The first housing 11 has an air outlet 111 for the user to inhale on the proximal end 110.

[0084] In one embodiment, the first housing 11 at least partially surrounds and is securely connected to the second housing 12. Specifically, for example, a first connecting structure 121, such as a protrusion, is arranged on the portion of the second housing 12 that extends into the first housing 11, and a second connecting structure, such as a groove, is arranged on the inner surface of the first housing 11; when the second housing 12 is partially inserted into the first housing 11, the first connecting structure 121, such as the protrusion, and the second connecting structure, such as the groove, cooperate to provide a connection between the first housing 11 and the second housing 12.

[0085] In one embodiment, the third housing 13 at least partially surrounds and is securely connected to the second housing 12. Specifically, for example, a tight-fitting structure 122, such as a rib, is arranged on the portion of the second housing 12 that extends into the third housing 13; when the second housing 12 is partially inserted into the third housing 13, an interference fit or tight fit is formed between the tight-fitting structure 122, such as the rib, and the third housing 13, thereby providing a connection between the second housing 12 and the third housing 13.

[0086] See Figures 2 to 10 As shown, the outer body or outer shell 10 contains:

[0087] A reservoir 123 is provided for storing a liquid matrix. In one embodiment, the reservoir 123 is primarily formed within the second housing 12. In one embodiment, the side of the reservoir 123 facing the proximal end 110 is closed by a first sealing element 14. In one embodiment, a liquid outlet 1231 is arranged on the side of the reservoir 123 facing the distal end 120 to allow the liquid matrix to exit the reservoir 123. Figure 10 In the illustrated embodiment, the liquid outlet 1231 is defined by the second housing 12. And in Figure 10 As shown, the liquid outlet 1231 is located between the liquid storage chamber 123 and the holding chamber 129. And in Figure 10 As shown, the liquid storage chamber 123 and the holding chamber 129 are connected by a liquid outlet 1231. In this embodiment, the liquid outlet 1231 of the liquid storage chamber 123 is arranged towards the distal end 120.

[0088] See Figures 2 to 7 As shown, the atomizer 100 establishes a conductive connection with the power supply mechanism 200 via an electrode assembly 20 located near and defining the distal end 120. Specifically, when the atomizer 100 is connected to the power supply mechanism 200, the electrode assembly 20 forms an electrical connection with the electrode contacts 230, thereby supplying power to the atomizer 100. Specifically, the electrode assembly 20 includes:

[0089] First electrode 21 and second electrode 22; in use, one of the first electrode 21 and the second electrode 22 is used as the positive electrode and the other as the negative electrode. In an embodiment, the first electrode 21 and the second electrode 22 are used to supply power to the atomizing assembly 40 or to guide current on the heating element of the atomizing assembly 40.

[0090] In one embodiment, the first electrode 21 is configured as a longitudinally extending annular ring, having a first segment 211 and a second segment 212 with different outer diameters; wherein the second segment 212 is closer to the distal end 120 and defines the distal end 120. In another embodiment, the first segment 211 is a ring arranged substantially perpendicular to the longitudinal direction of the atomizer 100; the first segment 211 has a relatively thin thickness, for example, approximately 0.2 mm to 2.0 mm. The second segment 212 is substantially a cylindrical shape extending longitudinally along the atomizer 100; for example, the second segment 212 has a length of approximately 3 to 8 mm. Furthermore, the surface of the second segment 212 is provided with external threads for forming a detachable connection with an internal thread adapted to the power supply mechanism 200.

[0091] In this embodiment, the second electrode 22 is essentially an annular ring arranged coaxially with the first electrode 21; the second electrode 22 is housed and held within a second segment 212 of the first electrode 21. Both the first electrode 21 and the second electrode 22 are made of a low-resistivity metal or alloy, such as gold, silver, copper, nickel, or alloys containing them.

[0092] After assembly, the surface of the second electrode 22 at its distal end 120 is substantially flush with the second segment 212 of the first electrode 21, thus exposing at least partially the second electrode 22 at its distal end 120. This allows the second segment 212 of the first electrode 21 and the second electrode 22 to form conductive contact with the power supply mechanism 200.

[0093] See Figures 2 to 7 As shown, the electrode assembly 20 also includes:

[0094] A flexible insulating element 23, which is essentially annular, such as a flexible silicone ring, is located within a second segment 212 of the first electrode 21 and surrounds the second electrode 22 to provide insulation between the second segment 212 of the first electrode 21 and the second electrode 22.

[0095] See Figures 2 to 7 As shown, a first air inlet 213 is arranged on the second section 212 of the first electrode 21 to allow external air to enter into the atomizer 100 during suction. In this embodiment, the first air inlet 213 is arranged to avoid the external threads on the outer surface of the second section 212.

[0096] See Figures 2 to 7As shown, the second electrode 22 defines a second air inlet 222 facing the distal end 120 for supplying external air into the atomizer 100 during suction.

[0097] In embodiments, the atomizer 100, which simultaneously has a first air inlet 213 and a second air inlet 222, can be compatible with more power supply mechanisms 200. For example, in some embodiments, when the atomizer 100 is combined with some power supply mechanisms 200, the power supply mechanism 200 can cover and close the first air inlet 213 while keeping the second air inlet 222 open to allow air to enter the atomizer 100 from the second air inlet 222; or in some embodiments, when the atomizer 100 is combined with some power supply mechanisms 200, the power supply mechanism 200 can keep the first air inlet open and cover and close the second air inlet 222 to allow air to enter the atomizer 100 from the first air inlet.

[0098] See Figures 2 to 7 As shown, the outer body or outer casing 10 is provided with multiple components for atomizing and outputting the liquid matrix, specifically including:

[0099] The tubular element 60 has a first portion 61, a second portion 62, and a third portion 63 arranged sequentially along the longitudinal direction; the outer / inner diameters of the first portion 61, the second portion 62, and the third portion 63 increase sequentially. The first portion 61 faces or is close to the proximal end 110, and the third portion 63 faces or is close to the distal end 120. In an embodiment, the tubular element 60 is arranged along the longitudinal central axis of the atomizer 100.

[0100] After assembly, the first portion 61 of the tubular element 60 is at least partially inserted into the first housing 11 and supported or abutted by the first housing 11 to form a stop. In some embodiments, the first housing 11 and the first portion 61 of the tubular element 60 are connected by riveting or interference fit. The third portion 63 of the tubular element 60 abuts against the insertion portion 124 in the second housing 12 to form support or abutment. The third portion 63 of the tubular element 60 and the insertion portion 124 in the second housing 12 are connected by riveting or interference fit.

[0101] After assembly, the tubular element 60 is substantially contained and held within the second housing 12; a reservoir 123 for storing a liquid matrix is ​​defined between the outer surface of the tubular element 60 and the inner surface of the second housing 12.

[0102] according to Figures 2 to 7 As shown, the atomizer 100 also includes:

[0103] The first sealing element 14, made of flexible silicone or thermoplastic elastomer, blocks and seals the side of the reservoir 123 facing the proximal end 110. In an embodiment, the first sealing element 14 is also at least partially configured to provide a seal between the first housing 11 and the first portion 61 of the tubular element 60. In an embodiment, the first portion 61 of the tubular element 60 extends from the second housing 12 through the first sealing element 14 and is inserted into or extends into the first housing 11.

[0105] The atomizing assembly 40 is configured to at least partially receive a liquid matrix originating from the reservoir 123 and heat and atomize it to generate an aerosol for suction. In one embodiment, the atomizing assembly 40 is mounted or arranged between the reservoir 123 and the support 70. In another embodiment, the atomizing assembly 40 is mounted or held within a holding cavity 129 defined by the second housing 12.

[0106] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, the atomizing assembly 40 defines an atomizing surface 432. In this embodiment, the atomizing surface 432 is arranged facing the distal end 120, and the atomizing surface 432 is arranged away from the liquid reservoir 123.

[0107] In an embodiment, a heating element (not shown) is formed or arranged on the atomizing surface 432 of the atomizing assembly 40 for heating the liquid matrix to generate an aerosol. The aerosol generated by the heating element is released or overflows from the atomizing surface 432. In an embodiment, the atomizing surface 432 is a plane arranged substantially perpendicular to the longitudinal direction of the atomizer 100.

[0108] according to Figures 2 to 9 As shown, the atomizer 100 also includes:

[0109] A support 70 is housed or mounted within a third housing 13 and is at least partially located between the second housing 12 and the first electrode 21. In some embodiments, the support 70 is rigid; for example, the support 70 may be made of ceramic, metal, or organic polymer plastic. And in embodiments, the support 70 and the second housing 12 are mechanically connected; for example, in… Figure 3 and Figure 4 As shown, a latching protrusion 76 is arranged on the bracket 70; after assembly, a part of the bracket 70 extends into the second housing 12 and is connected to the latching groove on the inner surface of the second housing 12 through the latching protrusion 76.

[0110] exist Figure 3 and Figure 4In the illustrated embodiment, a first positioning structure 74 is arranged on the bracket 70 for providing positioning during the assembly of the bracket 70 and the second housing 12. Specifically... Figure 3 and Figure 4 In this configuration, the first positioning structure 74 is a protruding ridge extending axially along the bracket 70; correspondingly, the second housing 12 is provided with a second positioning structure adapted to the first positioning structure 74, such as a recess into which the protruding ridge extends. Furthermore, after the bracket 70 and the second housing 12 are assembled, the first positioning structure 74 and the second positioning structure of the second housing 12 cooperate to prevent relative rotation of the bracket 70 and the second housing 12.

[0111] according to Figures 2 to 9 As shown, the atomizer 100 also includes:

[0112] Atomizing chamber 430 is formed or defined between atomizing assembly 40 and support 70; more specifically, a gap exists between support 70 and atomizing assembly 40 / atomizing surface 432, thereby forming or defining atomizing chamber 430. In use, the liquid matrix received by atomizing assembly 40 is heated by a heating element on atomizing surface 432 to generate an aerosol, which is then released or overflows from atomizing surface 432 into atomizing chamber 430.

[0115] In some embodiments, the first electrical contact 51 and / or the second electrical contact 52 extend substantially longitudinally along the atomizer 100; for example, in some embodiments, the first electrical contact 51 and / or the second electrical contact 52 are configured as elongated conductive needles. In embodiments, the first electrical contact 51 and / or the second electrical contact 52 are rigid, rather than spring-loaded. In embodiments, the length / diameter of the first electrical contact 51 is greater than the length / diameter of the second electrical contact 52; the relatively larger volume of the first electrical contact 51 compared to the second electrical contact 52 is advantageous for providing identification of differences in shape during assembly.

[0116] In this embodiment, the first electrical contact 51 and / or the second electrical contact 52 are securely mounted or held on the bracket 70. Specifically... Figure 3 and Figure 4In the bracket 70, a first contact hole 72 and a second contact hole 73 are arranged at intervals. During assembly, the first electrical contact 51 is at least partially accommodated or installed in the first contact hole 72 and is fastened to the bracket 70 by riveting or interference fitting. The second electrical contact 52 is at least partially accommodated or installed in the second contact hole 73 and is fastened to the bracket 70 by riveting or interference fitting. In an embodiment, the first contact hole 72 of the bracket 70 is a through hole, and the first electrical contact 51 penetrates the bracket 70 after assembly. In another embodiment, the second contact hole 73 of the bracket 70 is a blind hole, and the second electrical contact 52 does not penetrate the bracket 70; for example... Figure 7 As shown, the second electrical contact 52 does not extend beyond the surface of the bracket 70 facing the distal end 120.

[0117] In this embodiment, the first electrical contact 51 and / or the second electrical contact 52 longitudinally abut against the atomizing surface 432 of the atomizing assembly 40, thereby forming an electrical connection with the heating element on the atomizing surface 432. Furthermore, after assembly, the first electrical contact 51 and / or the second electrical contact 52 longitudinally abut against the atomizing surface 432 of the atomizing assembly 40, at least partially providing longitudinal support to the atomizing assembly 40.

[0118] In this embodiment, the first electrical contact 51 is electrically connected to the first electrode 21 via a first electrical connection element or a first electrical connection method; the second electrical contact 52 is electrically connected to the second electrode 22 via a second electrical connection element or a second electrical connection method. The first electrical connection element is different from the second electrical connection element; or, the first electrical connection method is different from the second electrical connection method.

[0119] In one embodiment, the first electrical connection element includes or may include a conductive spring 511. In another embodiment, the second electrical connection element is a conductive lead 521.

[0120] In one embodiment, the first electrical connection element is elastic, thereby being elastically arranged between the first electrical contact 51 and the first electrode 21 to provide a conductive connection; after assembly, the first electrical connection element is at least partially compressed between the first electrical contact 51 and the first electrode 21.

[0121] In this embodiment, the second electrical connection element is bendable. During assembly, the second electrical connection element is bent to make conductive connection with the second electrical contact 52 and / or the second electrode 22.

[0122] Specifically, in this embodiment, the first electrical contact 51 is electrically connected to the first electrode 21 via a conductive spring 511. Figures 3 to 9As shown, the first electrical contact 51 extends through the bracket 70. The conductive spring 511 is a longitudinally arranged helical spring. After assembly, the conductive spring 511 at least partially surrounds the first electrical contact 51, with one end of the conductive spring 511 abutting against the first electrical contact 51 and the other end abutting against the first electrode 21, thereby establishing a conductive connection between the first electrode 21 and the first electrical contact 51. More specifically, the conductive spring 511 abuts against a first section 211 of the first electrode 21.

[0123] Specifically, in this embodiment, the second electrical contact 52 is electrically connected to the second electrode 22 via a conductive lead 521. Figures 3 to 9 As shown, a portion of the slender conductive lead 521 extends into the second contact hole 73 and abuts against the outer surface of the second electrical contact 52 to form conductivity, while another portion passes through the bracket 70 and extends into the insulating element 23 to abut against the outer surface of the second electrode 22 to form conductivity, thereby establishing a conductive connection between the second electrical contact 52 and the second electrode 22.

[0124] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, the atomizing component 40 includes:

[0125] A porous element 43 forms or defines an atomizing surface 432; alternatively, the atomizing surface 432 is disposed on the porous element 43. The porous element 43 is rigid. A heating element is formed or incorporated into the atomizing surface 432 of the porous element 43. In some embodiments, the heating element is made of a resistive material, such as a composite material of a metal, metal alloy, graphite, carbon, conductive ceramic, or other ceramic and metal materials with appropriate resistance. In some embodiments, the heating element is arranged as a resistance heating track, coating, or patterned heating pattern, etc., formed on the atomizing surface 432.

[0126] In some embodiments, the porous element 43 is a liquid-permeable porous structure. In some embodiments, the porous element 43 includes a typical porous material, such as a rigid foam metal, porous ceramic, porous glass, etc., formed by sintering a mixture of raw materials of the matrix with a pore-forming agent; and the disordered micropores arranged in large quantities inside the porous element 43, defined by the sintering of the pore-forming agent, absorb and transfer the liquid matrix.

[0127] Alternatively, in some embodiments, the porous element 43 includes a plurality of liquid-guiding holes with predetermined directions formed on a dense matrix material such as dense ceramic or dense glass, thereby forming a porous structure; for example, in some embodiments, the liquid-guiding holes with predetermined directions in the porous element 43 can be formed by mechanical drilling, laser drilling, or chemical etching. In embodiments, the plurality of liquid-guiding holes extend or penetrate along the thickness direction of the porous element 43. The liquid-guiding holes penetrate the porous element 43 along its thickness direction. The liquid-guiding holes penetrate or extend from the first surface 322 to the atomizing surface 432. In use, the liquid matrix is ​​delivered from the liquid-absorbing surface 431 to the atomizing surface 432 through capillary wetting of the liquid-guiding holes and heated and atomized by the heating element. In embodiments, the plurality of liquid-guiding holes are arranged in an orderly manner within the porous element 43. The extension of the plurality of liquid-guiding holes is in a predetermined direction, rather than randomly. In the embodiments, a plurality of liquid guiding holes are arranged in an array within the porous body element 43; and in the embodiments, the plurality of liquid guiding holes are capable of transferring the liquid matrix from the liquid absorption surface 431 to the atomizing surface 432 at a predetermined rate.

[0128] In some embodiments, the porous element 43 is configured as a sheet arranged longitudinally perpendicular to the atomizer 100. The liquid-absorbing surface 431 and the atomizing surface 432 are arranged opposite to each other along the thickness direction of the porous element 43. The liquid-absorbing surface 431 is used to absorb or receive liquid matrix originating from the reservoir 123. In some other variations, the porous element 43 may also be other regular or irregular shapes; for example, an arched shape. In some embodiments, the liquid-absorbing surface 431 and / or the atomizing surface 432 of the porous element 43 are flat, extending planes; or in some other variations, the liquid-absorbing surface 431 and / or the atomizing surface 432 are curved surfaces, such as concave or convex arc surfaces.

[0129] In some embodiments, the thickness of the porous element 43 is 0.1 mm to 2 mm; more preferably, the thickness of the porous element 43 is 0.2 mm to 1 mm; specifically, the thickness of the porous element 43 is 0.5 mm. The length of the porous element 43 is 4 mm to 8 mm; specifically, the length of the porous element 43 may be 6 mm. The width of the porous element 43 is approximately 2 mm to 5 mm; specifically, the length of the porous element 43 may be 3 mm.

[0130] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, the atomizing component 40 also includes:

[0131] A flexible capillary element 42 is used to receive and retain the liquid matrix in the reservoir 123. It includes at least one of cotton fibers, cellulose fibers, hemp fibers, Tencel, and chemically synthesized fibers, such as a nonwoven fabric made from viscose fibers. Preferably, the capillary element 42 comprises natural fibers rather than man-made fibers. As a suitable example, the sheet-like capillary element 42 has a thickness of approximately 0.5 to 2 mm.

[0132] In this embodiment, the flexible capillary element 42 is attached to the liquid-absorbing surface 431 of the porous element 43. In use, the liquid-absorbing surface 431 of the porous element 43 indirectly absorbs the liquid matrix originating from the storage chamber 123 through the capillary element 42. In use, the capillary element 42 is used to buffer or store the liquid matrix on and near the liquid-absorbing surface 431; or the capillary element 42 is configured as a liquid storage layer or a liquid matrix buffer layer. When the heating element attached to the atomizing surface 432 starts heating atomization and rapidly consumes the liquid matrix, the capillary element 42 can quickly replenish the buffered or stored liquid matrix to the atomizing surface 432 to prevent excessive consumption of the liquid matrix on the atomizing surface 432, which could lead to dry burning or pasting.

[0133] In some embodiments, the length and / or width of the capillary element 42 is slightly smaller than the length or width of the porous element 43. After assembly, the capillary element 42 does not completely cover the liquid-absorbing surface 431. In some embodiments, the length of the capillary element 42 is approximately between 3 and 6 mm; specifically, the length of the capillary element 42 may be 5 mm. The width of the capillary element 42 is approximately between 2 and 4 mm; specifically, the width of the capillary element 42 may be 2.4 mm.

[0134] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, the atomizing component 40 also includes:

[0135] A rigid clamping element 41 is attached to the side of the capillary element 42 opposite to the porous element 43. In use, the clamping element 41 restricts or retains the thickness or volume of the capillary element 42 to at least partially reduce the volume expansion caused by the capillary element 42 wetting the liquid matrix, which is advantageous in preventing leakage of the liquid matrix due to expansion. After assembly, the capillary element 42 is clamped between the rigid clamping element 41 and the porous element 43. Alternatively, after assembly, the clamping element 41, the capillary element 42, and the porous element 43 are arranged in a sequentially stacked configuration.

[0136] In one embodiment, the clamping element 41 has at least one or more liquid perforations 411, making the clamping element 41 liquid-permeable. In use, the capillary element 42 draws liquid matrix from the reservoir 123 through the liquid perforations 411 of the clamping element 41.

[0137] In some embodiments, the clamping element 41 may be made of a rigid metal alloy such as stainless steel, ceramic, or glass. In some embodiments, the clamping element 41 is substantially sheet-like. In some embodiments, the clamping element 41 may be generally annular. Alternatively, in some other embodiments, the clamping element 41 may have several or more liquid perforations 411, thereby making the clamping element 41 mesh-like.

[0138] In one embodiment, the clamping element 41, capillary element 42, and porous element 43 of the atomizing assembly 40 are arranged perpendicular to the longitudinal direction of the atomizer 100. Alternatively, in some other variations, the clamping element 41 and / or capillary element 42 and / or porous element 43 and / or atomizing surface 432 are arranged obliquely relative to the longitudinal direction of the atomizer 100. Alternatively, the clamping element 41 and / or capillary element 42 and / or porous element 43 and / or atomizing surface 432 have an angle of 0 to π / 2 with the longitudinal direction of the atomizer 100.

[0139] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, the atomizer 100 also includes:

[0140] A flexible second sealing element 30 is arranged in annular or cylindrical shape, at least partially surrounding or enclosing the atomizing assembly 40; the second sealing element 30 may be made of flexible silicone, thermoplastic elastomer, etc. Upon assembly, the second sealing element 30 is at least partially located within the retaining cavity 129 defined by the second housing 12, and provides a seal between the second housing 12 and the atomizing assembly 40.

[0141] After assembly, the clamping element 41, capillary element 42, and porous element 43 of the atomizing assembly 40 are surrounded or encircled by the second sealing element 30. Figure 12 As shown, an abutment step 32 is arranged within the second sealing element 30; the porous element 43 abuts against the abutment step 32. The abutment step 32 is substantially flush with the capillary element 42. After assembly, the abutment step 32 provides longitudinal cushioning to prevent the porous element 43 from longitudinally squeezing or compressing the capillary element 42, thereby affecting the transfer efficiency of the liquid matrix. Furthermore, in an embodiment, the porous element 43 and / or the clamping element 41 provide at least partial support within the flexible second sealing element 30 to prevent the flexible second sealing element 30 from contracting inward to squeeze the capillary element 42, thereby affecting the transfer efficiency of the liquid matrix.

[0142] exist Figure 12 In the illustration, the second sealing element 30 does not extend to the atomizing surface 432 of the porous element 43; or, the second sealing element 30 avoids the atomizing surface 432; it is advantageous to prevent the second sealing element 30 from being heated by the heat of the atomizing surface 432 / heating element.

[0143] according to Figures 2 to 9 , Figure 11 and Figure 12 As shown, a liquid clearance hole 31 is defined on the second sealing element 30; after assembly, the clearance hole 31 is aligned with the liquid outlet 1231 to avoid obstructing the flow of the liquid matrix from the liquid outlet 1231 to the atomizing assembly 40. Also, after assembly, at least one or more liquid perforations 411 on the clamping element 41 are located within the clearance hole 31. Furthermore, after assembly... Figures 3 to 9 As indicated by the middle arrow R1, the liquid matrix in the storage chamber 123 exits from the liquid outlet 1231 and flows through the liquid clearance hole 31 of the second sealing element 30 to the atomizing assembly 40. During use, the liquid matrix delivered to the atomizing assembly 40 flows sequentially through the liquid perforation 411 of the clamping element 41, the capillary element 42, and the porous element 43 before being heated and atomized by the heating element to generate an aerosol.

[0144] During assembly, the atomizing components 40 are first stacked and then assembled into the second sealing element 30, which surrounds and holds them. Then, the second sealing element 30 and the atomizing components 40 are assembled into the retaining cavity 129 of the second housing 12.

[0145] Alternatively, in some other embodiments, the atomizing assembly 40 may include only the clamping element 41 and the porous element 43, without the capillary element 42; or, the capillary element 42 may be optional.

[0146] To facilitate the assembly of the second sealing element 30 within the retaining cavity 129 of the second housing 12, according to Figure 10 As shown, the second housing 12 is also provided with:

[0147] A guide groove 1291 extends from the retaining cavity 129 toward the distal end 120. Specifically, the guide groove 1291 is aligned with or extends from a corner of the retaining cavity 129. When the second sealing element 30 is assembled into the retaining cavity 129, one corner of the second sealing element 30 can be positioned against or against the guide groove 1291 and then pushed into the retaining cavity 129 to provide guidance and positioning during assembly.

[0148] according to Figure 10As shown, the top wall of the retaining cavity 129 near the liquid storage cavity 123 is also provided with:

[0149] The sealing rib 1232 is arranged as a closed ring around the liquid outlet 1231. When the second sealing element 30 is assembled in the retaining cavity 129, the sealing rib 1232 abuts against the second sealing element 30 to at least partially squeeze or compress the second sealing element 30, thereby promoting a seal between them to prevent leakage of the liquid matrix flowing from the liquid outlet 1231 to the atomizing assembly 40 through the second sealing element 30 and the top wall of the retaining cavity 129 near the liquid storage cavity 123.

[0150] Alternatively, in some variations, the sealing rib 1232 may be arranged on the surface of the second sealing element 30 facing the reservoir 123. The sealing rib 1232 may be arranged as a closed ring around the clearance hole 31.

[0151] according to Figures 2 to 9 As shown, the atomizer 100 also includes:

[0152] The airflow channel defines the airflow path from the first air inlet 213 and / or the second air inlet 222 through the atomizing chamber 430 / atomizing surface 432 to the air outlet 111, thereby outputting the aerosol to the air outlet 111.

[0153] In this embodiment, the complete airflow channel is defined by multiple components.

[0154] according to Figures 2 to 9 Middle arrows R21 and R22 indicate airflow channels including:

[0155] The air intake section provides a path for external air to enter the atomizing chamber 430 from the first air intake 213 and / or the second air intake 222. In an embodiment, the air intake section may include:

[0156] The first air intake section, indicated by arrow R21, allows external air to enter through the first air intake port 213 and then pass through the air hole 71 of the bracket 70 into the atomizing chamber 430.

[0157] And / or, the second air intake section indicated by arrow R22, through which external air enters the second air intake 222 and passes through the air hole 71 of the bracket 70 into the atomizing chamber 430.

[0158] In this embodiment, the second electrode 22 is hollow and defines a connecting hole 221 exposed within the first electrode 21. In this embodiment, as... Figure 8 As indicated by the middle arrow R22, the external air entering through the second air inlet 222 passes through the second electrode 22 and enters the first electrode 21 through the connecting hole 221, and then passes through the air hole 71 of the bracket 70 to enter the atomizing chamber 430.

[0159] In this embodiment, along the longitudinal direction of the atomizer 100, the air vents 71 of the support 70 are aligned with the atomizing surface 432 of the atomizing assembly 40. Alternatively, the projection of the air vents 71 along the longitudinal direction of the atomizer 100 onto the atomizing surface 432 is substantially within the atomizing surface 432.

[0160] according to Figures 2 to 9 The airflow channel, indicated by the middle arrow R3, also includes:

[0161] The aerosol output section provides a path for air to carry the aerosol from the atomizing chamber 430 to the air outlet 111. The aerosol output section includes:

[0162] An air compartment 126 is formed or defined within the second housing 12; the air compartment 126 is in communication with the atomizing chamber 430;

[0163] The hollow space formed or defined within the insertion portion 124;

[0164] The hollow part of the tubular element 60;

[0165] The first shell 11 is hollow.

[0166] according to Figures 2 to 9 As shown by the middle arrow R3, the air in the atomizing chamber 430 carrying the aerosol passes through the air compartment 126, the hollow part of the plug-in part 124, the tubular element 60 and the hollow part of the first housing 11 in sequence before being output to the air outlet 111 and drawn in by the user.

[0167] In this embodiment, the atomizer 100 further includes:

[0168] A porous absorption element 80 is mounted or held between the first electrode 21 and the support 70; the absorption element 80 surrounds or encloses the arrangement of the airflow channel for absorbing aerosol condensate seeping out against the airflow direction. In an embodiment, the absorption element 80 is made of a porous material such as porous fiber cotton. In an embodiment, the absorption element 80 is configured as an annular structure with pores 81; the pores 81 are for allowing air to pass through to avoid obstructing the airflow. In an embodiment, the pores 81 of the absorption element 80 and the pores 71 of the support 70 are partially overlapped and partially offset, rather than completely aligned or overlapping.

[0169] In one embodiment, the portion of the airflow channel surrounded and defined by the insertion portion 124, the tubular element 60, and the first housing 11 is arranged substantially along the longitudinal central axis of the atomizer 100. Alternatively, in another embodiment, the portion of the airflow channel extending within the liquid reservoir 123 is arranged along the longitudinal central axis of the atomizer 100.

[0170] In this embodiment, the atomizing assembly 40 and / or the atomizing surface 432 and / or the porous element 43 and / or the heating element are arranged off-center from the longitudinal central axis of the atomizer 100. In this embodiment, there is only one liquid outlet 1231; and the liquid outlet 1231 is off-center from the longitudinal central axis of the atomizer 100.

[0171] Specifically according to Figures 5 to 10 As shown, the second housing 12 contains:

[0172] A first partition wall 125 is arranged substantially within the second housing 12, extending longitudinally along the second housing 12; the first partition wall 125 at least partially isolates and defines the retaining cavity 129. Upon assembly, the atomizing assembly 40 and / or the retaining cavity 129 are located on a first side of the first partition wall 125, offset from the longitudinal central axis of the atomizer 100. An air chamber 126 is located on a second side of the first partition wall 125, offset from the longitudinal central axis of the atomizer 100. In this embodiment, the first partition wall 125 provides isolation between the retaining cavity 129 and the air chamber 126.

[0173] In an embodiment, the first partition wall 125 and / or the insertion portion 124 are integrally molded with the second housing 12.

[0174] In an embodiment, the area of ​​the atomizing surface 432 is larger than the cross-sectional area of ​​the portion of the airflow channel surrounded and defined by the tubular element 60; this is advantageous for maintaining the degree of dilution of the aerosol generated by the atomizing surface 432 within a predetermined range when it is transferred within the tubular element 60. More preferably, the cross-sectional area of ​​the portion of the airflow channel surrounded and defined by the tubular element 60 is between 0.3 and 0.9 times the area of ​​the atomizing surface 432. For example, in some embodiments, the inner diameter of the tubular element 60 may be between 3 and 4.5 mm.

[0175] In one embodiment, the insertion portion 124 extends from the first partition wall 125 toward the proximal end 110. An airflow communication hole 1251 is provided on the first partition wall 125; the airflow communication hole 1251 provides air communication between the air chamber 126 and the hollow space of the insertion portion 124. In use, air carrying aerosol is output downstream from the air chamber 126 via the airflow communication hole 1251.

[0176] In one embodiment, the airflow communication hole 1251 is closer to the proximal end 110 than the liquid outlet 1231.

[0177] according to Figures 5 to 10 As shown, the second housing 12 contains:

[0178] The second partition wall 127 is located on the second side of the first partition wall 125; alternatively, the second partition wall 127 extends from the first partition wall 125 to the inner surface of the second housing 12. The second partition wall 127 is arranged substantially perpendicular to the longitudinal direction of the atomizer 100. In an embodiment, the second partition wall 127 is located between the air compartment 126 and the liquid reservoir 123 in the longitudinal direction of the atomizer 100.

[0179] In one embodiment, the second partition wall 127 at least partially defines the boundary of the reservoir 123 toward the distal end 120. In another embodiment, the second partition wall 127 is closer to the proximal end 110 than the liquid outlet 1231.

[0180] exist Figures 3 to 10 In the embodiment shown, the second partition wall 127 extends in the circumferential direction of the atomizer 100 by an arc less than or equal to π.

[0181] according to Figures 3 to 9 As shown, the atomizer 100 also includes:

[0182] Ventilation passage R4 provides a pathway to connect the liquid reservoir 123 to the outside or ambient air, thereby balancing the pressure between the liquid reservoir 123 and the outside. More specifically, ventilation passage R4 provides a pathway to connect the liquid reservoir 123 to the air compartment 126 / airflow passage / atomizing chamber 430. According to... Figures 3 to 9 As shown, the ventilation channel R4 passes through the second partition wall 127.

[0183] During use, as the user draws out the liquid matrix in the storage chamber 123 and the negative pressure in the storage chamber 123 gradually increases, the ventilation channel R4 provides a path for air to enter the storage chamber 123 from the air compartment 126, thereby alleviating the negative pressure in the storage chamber 123. Alternatively, when the atomizer 100 is subjected to environmental testing or transported at high altitude and low pressure, if the pressure in the storage chamber 123 is greater than or less than the external pressure, the ventilation channel R4 connects the storage chamber 123 to the external atmosphere, thereby balancing their pressures.

[0184] In some embodiments, the ventilation channel R4 has a width or diameter of approximately 0.2 to 2.0 mm; this is advantageous for preventing leakage of liquid matrix from the ventilation channel R4.

[0185] according to Figures 3 to 10 As shown, the atomizer 100 also includes:

[0186] The air guiding element 90 is basically in the shape of a column or plug and is arranged through the second partition wall 127; the air guiding element 90 can be made of flexible silicone or thermoplastic elastomer, or alternatively, it can be made of polymer plastics, etc.

[0187] After assembly, an air exchange passage R4 is formed or defined between the air guide element 90 and the second partition wall 127. Specifically, in Figure 10 As shown, the second partition wall 127 has a longitudinally penetrating ventilation groove 128 arranged on the inner wall of the mounting hole 1281 for assembling or accommodating the air guide element 90; and when the air guide element 90 is installed through the mounting hole 1281 of the second partition wall 127, the ventilation groove 128 defines and forms a ventilation channel R4 between the air guide element 90 and the second partition wall 127.

[0188] In some embodiments, the airflow path of the aerosol output passes through the air compartment 126, allowing the heated airflow to exchange heat with the air guide element 90. In some embodiments, the air guide element 90 may be made of a material with high thermal conductivity, such as aluminum alloy, copper alloy, or titanium alloy with a thermal conductivity greater than 60 W / mK. The air guide element 90 can be heated by the flowing airflow, which in turn heats the liquid matrix near the ventilation channel R4, thereby reducing the viscosity of the liquid matrix and making ventilation smoother. Alternatively, in some embodiments with other low-viscosity liquid matrices, the air guide element 90 may be made of conventional low-thermal-conductivity polymer plastics, ceramics, or silicone.

[0189] In some embodiments, the width and / or depth of the ventilation groove 128 is between 0.2 and 2.0 mm.

[0190] In this embodiment, the ventilation channel R4 / ventilation groove 128 avoids the liquid outlet 1231 of the liquid storage chamber 123 to prevent air bubbles entering the liquid storage chamber 123 through the ventilation channel R4 from forming bubbles that occupy the liquid outlet 1231 and affect the liquid flow. Specifically, in this embodiment, the liquid outlet 1231 is located on the first side of the first partition wall 125; and the ventilation channel R4 / ventilation groove 128 is located on the second side of the first partition wall 125.

[0191] In one embodiment, the ventilation channel R4 / ventilation groove 128 is closer to the proximal end 110 than the liquid outlet 1231, so that air bubbles formed by air entering the liquid storage chamber 123 through the ventilation channel R4 do not flow through the liquid outlet 1231. Alternatively, the ventilation channel R4 / ventilation groove 128 is located at the air outlet port within the liquid storage chamber 123, avoiding the liquid outlet 1231; and the air outlet port of the ventilation channel R4 / ventilation groove 128 on the inner surface of the liquid storage chamber 123 is closer to the proximal end 110 than the liquid outlet 1231. In a more preferred embodiment, for example... Figure 7 As shown, in the longitudinal direction of the atomizer 100, the air exchange channel R4 / air exchange groove 128 is located at the air outlet port on the inner surface of the liquid storage chamber 123, and has a height difference d11 between it and the liquid outlet 1231. In some embodiments, the height difference d11 is at least greater than 2 mm; for example, in Figure 7As shown, the height difference d11 is approximately 5.3 mm. Alternatively, the first distance between the liquid outlet 1231 and the proximal end 110 is at least 2 mm greater than the second distance between the venting port of the venting channel R4 / venting groove 128 located in the liquid storage chamber 123 and the proximal end 110.

[0192] In this embodiment, the ventilation channel R4 and the liquid outlet 1231 are located on both sides of the tubular element 60.

[0193] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
