Electronic atomizing device and liquid reservoir for electronic atomizing device

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410917907.8, filed on July 9, 2024, entitled “Electronic Atomizing Device and Liquid Reservoir for Electronic Atomizing Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device and a liquid reservoir for the electronic atomization device. Background Technology

[0004] 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.

[0005] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could 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 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 replenish the liquid matrix to a reusable body via a separate, replaceable liquid source.

[0006] Application content

[0007] One embodiment of this application provides an electronic atomizing device, comprising:

[0008] The atomizing body and the liquid reservoir can exist independently, and the liquid reservoir can be combined with the atomizing body by the user.

[0009] The atomizing unit includes:

[0010] The first liquid storage chamber is used to store the liquid matrix;

[0011] An atomizing component is used to receive the liquid matrix in the first liquid storage chamber and atomize it to generate an aerosol;

[0012] The liquid reservoir includes a first module and a second module. The first module defines a second liquid storage chamber for storing a liquid matrix. When the liquid reservoir is attached to the atomizing body, the second module is connected to the atomizing body, and the first module can move relative to the second module between a first position and a second position. When the first module is in the first position, the second module connects the liquid in the second liquid storage chamber with the liquid in the first liquid storage chamber, so that the liquid matrix in the second liquid storage chamber can be replenished to the first liquid storage chamber via the second module. When the first module is in the second position, the second module disconnects the liquid connection between the second liquid storage chamber and the first liquid storage chamber.

[0013] In some embodiments, when the reservoir is attached to the atomizing body, the first module is movable relative to the atomizing body, and the second module is immovable relative to the atomizing body.

[0014] In some embodiments, when the reservoir is attached to the atomizing body, the first module is configured to be movable relative to the second module along the longitudinal direction of the atomizing body by user operation.

[0016] When the first module is in the first position, the second liquid storage chamber is in liquid communication with the liquid buffer chamber. The liquid matrix stored in the second liquid storage chamber is flowed into the liquid buffer chamber for buffering and then delivered to the first liquid storage chamber via the liquid buffer chamber. When the first module is in the second position, the second liquid storage chamber is disconnected from the liquid buffer chamber.

[0027] The sealing area is formed or defined between the first sealing rib and the second sealing rib.

[0028] In some embodiments, the inner and / or outer diameter of the liquid outlet connector gradually decreases towards the free end.

[0029] In some embodiments, the second module is further provided with:

[0032] When the first module is in the first position, the sealing part can be driven by the second module to change from a sealed state to an open state, thereby connecting the ventilation channel with the air in the second liquid storage chamber; when the first module is in the second position, the sealing part can return from the open state to the sealed state, thereby disconnecting the air connection between the ventilation channel and the second liquid storage chamber.

[0033] In some embodiments, the second module is provided with a ventilation connector;

[0035] When the first module is in the second position, the venting connector moves out of the second liquid storage chamber and avoids the sealing part, thereby allowing the sealing part to return from the open state to the sealed state and disconnecting the air communication between the venting channel and the second liquid storage chamber.

[0044] In some embodiments, when the reservoir is attached to the atomizing body, the first connector and / or the second connector are inserted into the second module to prevent the second module from moving along the longitudinal direction of the atomizing body.

[0045] In some embodiments, it also includes:

[0046] The power supply mechanism includes a battery cell; the battery cell is used to provide power to the atomizing body;

[0047] The power supply mechanism also has a receiving cavity for receiving the atomizing body and the liquid reservoir; when the atomizing body and the liquid reservoir are received in the receiving cavity, at least a portion of the first module is located outside the receiving cavity and defines an operating part for user operation; in use, the user can drive the first module to move between a first position and a second position by operating the operating part.

[0048] In some embodiments, when the reservoir is removed from the atomizing body, the first module and the second module of the reservoir can be separated or detached relative to each other.

[0104] 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.

[0105] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0106] According to Figures 1 through 4, an electronic atomizing device in one embodiment 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. In the embodiment shown in Figure 1, the atomizer 100 and the 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 other variations, the atomizer 100 and the power supply mechanism 200 of the electronic atomizing device are securely enclosed and fixed by a housing component of the electronic atomizing device, so that the atomizer 100 and the power supply mechanism 200 cannot be detachable from each other from 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.

[0107] As shown in Figures 1 to 4, the power supply mechanism 200 includes:

[0108] The first end 210 and the second end 220 along the length direction;

[0109] The receiving cavity 211 is located near the first end 210 and is open at the first end 210; the receiving cavity 211 is used to removably receive at least a portion of the atomizer 100 through the open opening.

[0110] A flexible seal 260 is arranged perpendicular to the longitudinal direction of the power supply mechanism 200; the seal 260 divides at least a portion of the internal space of the power supply mechanism 200 to form the receiving cavity 211; 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 211 from flowing into the interior of the power supply mechanism 200; the seal 260 defines at least a portion of the boundary or surface of the receiving cavity 211;

[0111] A rigid support 230, made of ceramic or polymer plastic, is at least partially located between the seal 260 and the second end 220; the support 230 is configured to support and retain the seal 260.

[0112] The battery cell 240 is used to supply power to or output power to the atomizer 100; the battery cell 240 is located between the receiving cavity 211 and the second end 22; the battery cell 240 is supported or held by the bracket 230.

[0113] The first electrical contact 230 is at least partially exposed within the receiving cavity 211; when at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the first electrical contact 230 abuts against the second electrical contact 322 on the atomizer 100 to form a conductive connection for supplying power output from the battery cell 240 to the atomizer 100; the first electrical contact 230 extends from the support 230 into the receiving cavity 211;

[0114] A magnetic element 233 is arranged adjacent to the receiving cavity 211; when at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the magnetic element 233 is magnetically attracted to the magnetic element 323 on the atomizer 100, thereby stably receiving or holding the atomizer 100 within the receiving cavity 211. The magnetic element 233 is arranged on the support 230.

[0115] As shown in Figures 1 to 4, the power supply mechanism 200 also includes:

[0116] The charging interface 221, such as a USB-Type-C interface, is located at the second end 220 and is used to charge the battery cell 240.

[0117] As shown in Figures 1 to 4, the power supply mechanism 200 also includes:

[0118] The first air inlet 234 is located on the outer surface to provide an inlet for external air to enter the receiving cavity 211; the first air inlet 234 is connected to the receiving cavity 211 and is arranged close to the seal 260; the atomizer 100 is provided with a second air inlet 321. When at least a portion of the atomizer 100 is received and contained in the receiving cavity 211, the second air inlet 321 communicates with the first air inlet 234 through the gap between the atomizer 100 and the seal 260, so that the air entering through the first air inlet 234 enters the atomizer 100 through the second air inlet 321, as shown by arrow R1 in Figure 4;

[0119] An airflow sensor 250 is housed and held within a bracket 230; a sensing connection port 251 is also defined on the bracket 230, which is exposed within a receiving cavity 211; when at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the sensing connection port 251 is aligned with and connected to the second air inlet 321 of the atomizer 100; the airflow sensor 250 communicates with the airflow through the second air inlet 321 of the atomizer 100 via the sensing connection port 251, thereby sensing changes in airflow flowing through the atomizer 100 during user inhalation;

[0120] A circuit board (not shown in the figure), such as a PCB board or an FPC board, is arranged with circuitry; the circuitry is configured to control the supply of power from the battery cell 240 to the atomizer 100 based on the sensing result of the airflow sensor 250.

[0121] As shown in Figures 5 to 13, the atomizer 100 includes:

[0122] The proximal end 110 and distal end 120 are opposite in the longitudinal direction, and the first side 130 and the second side 140 are opposite in the width direction; wherein, according to the needs of normal use, the proximal end 110 is configured as the end for the user to inhale aerosol, and an air outlet 111 for the user to inhale is provided at the proximal end 110; while the distal end 120 is configured as the end to be combined with the power supply mechanism 200.

[0123] The atomizing body 30 and the liquid reservoir 40 are arranged sequentially along the width direction; wherein the atomizing body 30 is close to or defines the first side 130, and the liquid reservoir 40 is close to or defines the second side 140.

[0124] In some embodiments, the atomizing body 30 and the reservoir 40 can each exist independently, while also being combined with each other. In some embodiments, the atomizing body 30 is used to atomize a liquid matrix to generate an aerosol, and the reservoir 40, when combined with the atomizing body 30, can replenish the liquid matrix to the atomizing body 30. Before the atomizing body 30 and the reservoir 40 are combined, they exist independently of each other.

[0125] In some embodiments, the reservoir 40 can be attached to the atomizing body 30 along its width from the second side 140, and can also be detached or removed from the atomizing body 30; when the reservoir 40 is attached to the atomizing body 30, it can replenish the atomizing body 30 with liquid matrix; the reservoir 40 is replaceable, while the atomizing body 30 is reusable; after the liquid matrix in the reservoir 40 is replenished, the user can detach and replace it with a new reservoir 40 from the atomizing body 30. Alternatively, in some variations, once the reservoir 40 is attached to the atomizing body 30, it cannot be detached from the atomizing body 30; after the liquid matrix inside is consumed, it is recycled or discarded as a whole.

[0126] As shown in Figures 5 to 13, the atomizing body 30 includes several components disposed within a first housing 31 (which may be referred to as a housing). The overall design of the first housing 31 is variable, and the type or configuration of the first housing 31, which defines the overall size and shape of the atomizing body 30, is also variable. Typically, the first housing 31 may be formed from a single, integral housing, or the first housing 31 may be formed from two or more separable bodies. In some examples, all or only part of the first housing 31 may be formed from a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plated over plastic, ceramics, etc.

[0127] As shown in Figures 5 to 13, the first housing 31 is generally configured in an L-shape; specifically, the first housing 31 includes:

[0128] The first part 316 extends longitudinally and is close to or defines the first side 130; the first part 316 defines the proximal end 110 and defines the air outlet 111 located at the proximal end 110.

[0129] The second part 317 extends from the first part 316 along the width direction to the second side 140; the second part 317 has a gap with the proximal end 110, thereby forming or defining a holding space 150 between the second part 317 and the proximal end 110; the holding space 150 is close to the second side 140, and the exposed liquid reservoir 40 can be attached to the atomizing body 30 from the second side 140 along the width direction of the atomizing body 30, as shown by arrow P1 in FIG5.

[0130] When the reservoir 40 is attached to the atomizing body 30, the reservoir 40 abuts against the first portion 316 in width and against the second portion 317 in length.

[0131] As shown in Figures 5 to 13, the first portion 316 and the second portion 317 of the first housing 31 are open at the distal end 120 to allow for the installation of necessary functional components. The atomizing body 30 also includes:

[0132] End cap 32, arranged vertically to the atomizing body 30, for example in the form of a sheet; end cap 32 is located at the distal end 120 and is attached to the first housing 31, thereby closing the openings of the first part 316 and the second part 317 at the distal end 120. The sealing element 32 is connected to the first housing 31 by means of snaps, screws or fasteners.

[0133] As shown in Figures 5 to 13, the end cap 32 is provided with:

[0134] The second air inlet 321 is used to supply air into the atomizing body 30.

[0135] As shown in Figures 5 to 13, the second magnetic element 323 is mounted or held on the end cap 32 and is exposed at the distal end 120; the second electrical contact 322 extends from the end cap 32 into the atomizing body 30.

[0136] As shown in Figures 5 to 13, the first part 316 of the atomizing body 30 is arranged with:

[0137] An aerosol output tube 112 is arranged from an outlet 111 toward a distal end 120 for delivering aerosol to the outlet 111; in an embodiment, the aerosol output tube 112 is integrally molded with the first housing 31.

[0138] As shown in Figures 5 to 13, the first part 316 of the atomizing body 30 also includes:

[0139] A first tubular element 116 and a second tubular element 115 located within the first tubular element 116; the first tubular element 116 and the second tubular element 115 are arranged coaxially and extend longitudinally along the atomizing body 30; and a first liquid storage cavity is formed or defined between the first tubular element 116 and the second tubular element 115 for storing a liquid matrix;

[0140] A liquid holding element 33 is disposed in a first liquid storage cavity between a first tubular element 116 and a second tubular element 115; the liquid holding element 33 is made of a flexible or rigid porous material or fibrous material to adsorb and retain the liquid matrix stored in the first liquid storage cavity; the liquid holding element 33 and / or the first liquid storage cavity are substantially annular in shape.

[0141] In some embodiments, the first tubular element 116 and the second tubular element 115 are made of rigid ceramic, stainless steel or polymer plastic, etc.

[0142] In some embodiments, the liquid holding element 33 may be made of rigid porous materials such as porous ceramics or porous glass, or it may be made of flexible porous fibers such as porous cotton fibers, porous nonwoven fabrics or porous sponges.

[0143] In some embodiments, the liquid retention element 33 is defined by a single porous fiber element. Alternatively, in some further variations, the liquid retention element 33 includes a first porous fiber material layer and a second porous fiber material layer arranged sequentially in the axial direction. The first porous fiber material layer defines the upper surface of the liquid retention element 33, and the second porous fiber material layer defines the lower surface of the liquid retention element 33. The liquid retention element 33 is formed by stacking the first and second porous fiber material layers on top of each other.

[0144] In some embodiments, the second porous fiber material layer is made of a flexible capillary fiber material, such as natural cotton fiber, nonwoven fiber, etc.

[0145] In some embodiments, the first porous fiber material layer includes rayon, or rigid rayon or artificial foam made of filamentous polyurethane. For example, the first porous fiber material layer uses 138# rigid synthetic organic polymer fiber; or, for another example, the first porous fiber material layer uses 138# rigid synthetic organic polymer fiber with a density of 0.1–0.9 mg / mm². 3The density. The first porous fiber material layer is prepared from oriented fibers arranged substantially along its length, width, or radial direction. The arrangement of the oriented fibers along the length or width of the first porous fiber material layer gives it strong bending resistance and thus a rigid texture. Specifically, for example, the first porous fiber material layer may be rigid rayon comprising oriented polyester fibers, or rigid rayon or artificial foam composed of filamentous polyurethane, etc.

[0146] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0147] The first sealing element 114 is made of a flexible material such as silicone or thermoplastic elastomer; the first sealing element 114 is combined with or arranged at the first end of the first tubular element 116 and the second tubular element 115 toward the proximal end 110 to close or seal the first liquid reservoir at their first ends.

[0148] The flexible second sealing element 325 is made of a material such as flexible silicone or thermoplastic elastomer; the second sealing element 325 is combined with or arranged at the second end of the first tubular element 116 and the second tubular element 115 toward the distal end 120 to close or seal the first liquid reservoir at their second ends.

[0149] In some embodiments, a gap of approximately 0.5 to 2 mm exists between the liquid holding element 33 and the first sealing element 114; the gap between the liquid holding element 33 and the first sealing element 114 communicates with the external atmosphere through the pores of the first absorption element 113. Therefore, during use, as the liquid matrix in the first liquid storage chamber is gradually consumed, external air can enter the gap between the liquid holding element 33 and the first sealing element 114 to alleviate or eliminate the negative pressure in the first liquid storage chamber.

[0150] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0151] A porous first absorbent element 113 is made of a flexible fibrous material, such as suitable fibrous cotton. Upon assembly, the first absorbent element 113 is housed and held within a first sealing element 114. An aerosol outlet tube 112 extends from an outlet 111 to the first absorbent element 113, abuts against, and terminates at the first absorbent element 113, which is located between a second tubular element 115 and the aerosol outlet tube 112. In one aspect, the first absorbent element 113 is used to absorb aerosol condensate generated in the airflow delivered to the aerosol outlet tube 112 during suction; in another aspect, the first absorbent element 113 can also absorb aerosol condensate falling from the inner surface of the aerosol outlet tube 112. As an optional example, the first absorbent element 113 is generally arranged in an annular sheet shape. An airflow channel passes through the first absorbent element 113.

[0152] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0153] An atomizing assembly, located within the second tubular element 115 and in fluid communication with the liquid holding element 33 and / or the first liquid reservoir, is used to draw in a liquid matrix and atomize it to generate an aerosol. Referring to Figures 5 to 13, the atomizing assembly includes:

[0154] Liquid guiding element 36 and heating element 37 attached to liquid guiding element 36.

[0155] In some embodiments, the liquid guiding element 36 is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the liquid guiding element 36 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the first housing 31; the liquid guiding element 36 is coaxial with the liquid holding element 33 and / or the second tubular element 115 and is located within the liquid holding element 33 and / or the second tubular element 115. Alternatively, in some other variations, the liquid guiding element 36 may also include a rigid porous element, such as porous ceramic or porous glass. The outer surface of the liquid guiding element 36 is in fluid communication with the liquid holding element 33 and / or the first liquid reservoir, thereby allowing the outer surface of the liquid guiding element 36 to draw liquid matrix from the liquid holding element 33 and / or the first liquid reservoir, as shown by arrow R2 in FIG11.

[0156] In some embodiments, the liquid guiding element 36 is surrounded and held by the liquid holding element 33 and contacts the liquid holding element 33 to form fluid communication. Alternatively, in some other embodiments, the liquid guiding element 36 is held within a second tubular element 115, which has a plurality of perforations; the liquid guiding element 36 draws liquid matrix from the liquid holding element 33 and / or the first reservoir cavity through the perforations in the second tubular element 115.

[0157] The inner surface of the liquid guiding element 36 in the radial direction is configured as an atomizing surface, which is combined / attached / abutted to the heating element 37; subsequently, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 37 to generate an aerosol and released. Referring to Figures 5 to 13, the heating element 37 is arranged to extend longitudinally along the liquid guiding element 36, and the heating element 37 is coaxially arranged with the liquid guiding element 36. In some optional embodiments, the heating element 37 is a resistance heating mesh, resistance heating coil, etc. In this embodiment, the heating element 37 is a heating element wound from a sheet-like or mesh-like substrate. Conductive leads are welded or arranged at both ends of the heating element 37 and connected to a second electrical contact 322 via conductive leads for guiding current in the heating element 37.

[0158] In some variations, the heating element 37 may be attached to the liquid guiding element 36 by means of printing, deposition, sintering, or physical assembly. In some other variations, the liquid guiding element 36 may have a planar or curved surface for supporting the heating element 37, which is formed on the planar or curved surface of the liquid guiding element 36 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 37 is a conductive trace formed on the surface of the liquid guiding element 36. In some variations, the conductive trace of the heating element 37 may be in the form of printed lines formed by printing. In some variations, the heating element 37 is a patterned conductive trace. In some variations, the heating element 37 is planar. In some variations, the heating element 37 is a tortuous, meandering, reciprocating, or zigzag extended conductive trace.

[0159] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0160] The annular support element 35 extends at least partially from the second end of the second tubular element 115 into the second tubular element 115, and at least partially abuts against and supports the liquid guiding element 36.

[0161] After assembly, the support element 35 is at least partially located on the second tubular element 115 and the second sealing element 325; the second end of the second tubular element 115 abuts against the support element 35.

[0162] In some embodiments, the support element 35 is annular in shape, and a plurality of circumferentially spaced wire grooves are arranged on its outer surface. During assembly, the two conductive leads connected to the heating element 37 are respectively confined in the wire grooves to form isolation, thereby preventing problems such as the two conductive leads connected to the heating element 37 abutting or contacting each other and causing short circuits during assembly.

[0163] As shown in Figure 11, a support flange 117 extending radially inward is also arranged inside the first tubular element 116; after assembly, the second sealing element 325 partially extends into the first tubular element 116 and abuts against the support flange 117.

[0164] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0165] A porous capillary element 34, for example made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge, is located within the first liquid reservoir. The capillary element 34 is configured in an annular shape and is located between the support flange 117 and the liquid holding element 33. The capillary element 34 and the liquid holding element 33 are in contact or abutment, and thus they are in liquid communication.

[0166] As shown in Figures 5 to 13, the capillary element 34 partially surrounds the second tubular element 115, and there is a gap between the capillary element 34 and the second tubular element 115. Specifically, as shown in Figures 5 to 13, the second sealing element 325 partially extends between the capillary element 34 and the second tubular element 115, thereby isolating or separating them.

[0167] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0168] An airflow channel is formed or defined between the second air inlet 321 and the air outlet 111 to define or provide an airflow path from the second air inlet 321 through the heating element 37 to the air outlet 111, thereby outputting the aerosol to the air outlet 111. As shown in Figures 5 to 13, the complete airflow channel is defined by multiple components. Specifically, as shown by arrow R1 in Figures 5 to 13, external air entering from the second air inlet 322 passes sequentially through the second sealing element 325 and the support element 35 before being delivered to the heating element 37; then it passes through the heating element 37 and carries the heated aerosol sequentially through the second tubular element 115, the first sealing element 114, the first absorption element 113, and the aerosol output pipe 112 to the air outlet 111 where it is drawn in by the user.

[0169] As shown in Figures 5 to 13, the atomizing body 30 also includes:

[0170] A porous second absorbent element 326, such as fiber cotton, is arranged adjacent to or around the second air inlet 321 to absorb aerosol condensate flowing towards the second air inlet 321 within the airflow channel. As shown in Figures 5 to 13, the second absorbent element 326 is mounted or held between the end cap 32 and the second portion 317; alternatively, the second absorbent element 326 is between the end cap 32 and the first housing 31; or alternatively, the second absorbent element 326 is between the end cap 32 and the second sealing element 325.

[0171] As shown in Figures 5 to 13, the atomizing body 30 is also equipped with:

[0172] The first connector 1161 and the second connector 1162 extend at least partially through or into the holding space 150 from within the atomizing body 30 / first portion 316.

[0173] As shown in Figures 5 to 13, the first connector 1161 and the second connector 1162 extend from within the first portion 316 toward the second side 140 in the width direction; and the first connector 1161 and the second connector 1162 are at least partially exposed in the retaining space 150. As shown in Figures 5 to 13, the first portion 316 has a window 314 facing the second side 140; the first connector 1161 and the second connector 1162 extend from the window 314 into the retaining space 150.

[0174] In some embodiments, the first connector 1161 and the second connector 1162 are arranged longitudinally at a distance; and the second connector 1162 is closer to the second portion 317 / distal end 120 than the first connector 1161.

[0175] In some embodiments, the first connector 1161 and the second connector 1162 are hollow tubular structures; and the first connector 1161 and the second connector 1162 are in communication with the first liquid reservoir. Specifically, the tubular first connector 1161 and the second connector 1162 are integrally molded with the first tubular element 116; furthermore, the first connector 1161 and the second connector 1162 extend from the first tubular element 116. After assembly, the first connector 1161 and the second connector 1162 are opposite to the porous capillary element 34; furthermore, the first connector 1161 and the second connector 1162 are in fluid communication with the outer surface of the capillary element 34.

[0176] As shown in Figures 5 to 13, the second connector 116 is configured to provide a channel for replenishing the liquid matrix of the reservoir 40 to the first reservoir chamber. In use, as shown by arrow R31 in Figure 11, the liquid matrix in the reservoir 40 flows through the second connector 116 to the capillary element 34, where it is received and then transferred by the capillary element 34 to the liquid holding element 33, thereby allowing the reservoir 40 to replenish the liquid matrix to the first reservoir chamber / liquid holding element 33 through the second connector 116.

[0177] As shown in Figures 5 to 13, the first connector 1161 is configured to provide an air exchange channel that connects the first liquid reservoir to the liquid reservoir 40. When the liquid reservoir 40 replenishes the liquid matrix to the first liquid reservoir / liquid holding element 33 through the second connector 116, the air in the first liquid reservoir / liquid holding element 33 flows into the liquid reservoir 40 through the first connector 1161 to balance or regulate the pressure in the liquid reservoir 40.

[0178] As shown in Figures 5 to 13, a connecting structure is also arranged on the atomizing body 30 and the liquid reservoir 40 to prevent the liquid reservoir 40 from separating from the atomizing body 30 along the width direction when the liquid reservoir 40 is attached to the atomizing body 30. Specifically, the connecting structure includes:

[0179] The first connecting structure 312 is, for example, a latching protrusion formed or arranged on the surface of the first portion 316; the first connecting structure 312 is arranged in a groove 311 on the surface of the first portion 316;

[0180] The second connecting structure 411 is located on the reservoir 40 and is adapted to the first connecting structure 312; for example, the second connecting structure 411 is a connecting arm with a locking hole 412; when the reservoir 40 is attached to the atomizing body 30, the locking protrusion of the first connecting structure 312 extends into the locking hole 412 of the second connecting structure 411, thereby stably attaching the reservoir 40 to the atomizing body 30 to prevent the reservoir 40 from separating from the atomizing body 30 in the width direction.

[0181] As shown in Figures 5 to 13, the connecting structure allows the first module 410 of the reservoir 40 to move longitudinally relative to the atomizing body 30. For example, in Figures 5 to 13, when the reservoir 40 is attached to the atomizing body 30, the second connecting structure 411 extends into the groove 311. The longitudinal dimension of the groove 311 is larger than the longitudinal dimension of the second connecting structure 411; the longitudinal dimension of the locking hole 412 of the second connecting structure 411 is larger than the longitudinal dimension of the locking protrusion of the first connecting structure 312. This allows the first module 410 of the reservoir 40 and the atomizing body 30 to move longitudinally relative to each other when the first connecting structure 312 and the second connecting structure 411 are connected.

[0182] As shown in Figures 5 to 13, a positioning structure is also arranged between the atomizing body 30 and the liquid reservoir 40 to provide positioning when the liquid reservoir 40 is attached to the atomizing body 30. Specifically, the positioning structure includes:

[0183] A first positioning structure 313, such as a positioning hole 313 formed or arranged on the surface of the first portion 316;

[0184] A second positioning structure 413, for example, a positioning protrusion 413 formed or arranged on the surface of the reservoir 40.

[0185] When the reservoir 40 is attached to the atomizing body 30, the second positioning structure 413 can be aligned with the first positioning structure 313 to provide guidance. Accordingly, the longitudinal dimension of the positioning hole 313 is larger than the longitudinal dimension of the positioning protrusion 413, so that the positioning protrusion 413 can move longitudinally within the positioning hole 313, allowing the first module 410 of the reservoir 40 to move longitudinally relative to the atomizing body 30.

[0186] As shown in Figures 5 to 13, the reservoir 40 includes a first module 410 and a second module 420, which is advantageous for the assembly and fabrication of the reservoir 40. As shown in Figures 5 to 13, both the second connecting structure 411 and the second positioning structure 413 are formed or arranged in the first module 410.

[0187] As shown in Figures 5 to 13, the first module 410 of the reservoir 40 includes:

[0188] The second housing 41 at least partially defines the outer body of the reservoir 40; when the reservoir 40 is attached to the atomizing body 30, the second housing 41 of the reservoir 40 and the first housing 31 of the atomizing body 30 together define the complete outer shell of the atomizer 100. Furthermore, when the atomizer 100 is received within the receiving cavity 211 of the power supply mechanism 200, a portion of the outer shell of the atomizer 100 is located outside the power supply mechanism 200.

[0189] As shown in Figures 5 to 13, the second housing 41 has an operating portion 418 on the second side 140; the operating portion 418 is defined by a step, protrusion, or recess on the second side 140 of the second housing 41. In use, the operating portion 418 is configured to be operated by a user's finger, thereby driving the first module 410 of the reservoir 40 to move longitudinally relative to the atomizing body 30.

[0190] When the atomizer 100 is received in the receiving cavity 211 of the power supply mechanism 200, the operating part 418 of the second housing 41 is exposed outside the receiving cavity 211. Specifically, for example, the operating part 418 may abut against the first end of the power supply mechanism 200.

[0191] As shown in Figures 5 to 13, the first module 410 of the reservoir 40 further includes:

[0192] A second liquid reservoir 42 is formed or defined within the second housing 41 for storing a liquid matrix. The side of the second liquid reservoir 42 near the proximal end 110 is closed, and the side of the second liquid reservoir 42 facing the distal end 120 is open. In use, the liquid matrix within the second liquid reservoir 42 exits from the distal end 120.

[0193] As shown in Figures 5 to 13, the first module 410 of the reservoir 40 further includes:

[0194] The sealing element 43 is arranged substantially perpendicular to the longitudinal direction of the second housing 41. The sealing element 43 is positioned on the side of the second liquid reservoir 42 facing the distal end 120 and serves to seal the side of the first liquid reservoir 112 facing the distal end 120. A liquid outlet connector 431 is defined on the sealing element 43 to provide a pathway for the liquid matrix within the second liquid reservoir 42 to exit or exit. After assembly, the liquid matrix within the second liquid reservoir 42 can only exit or exit through the liquid outlet connector 431 of the sealing element 43. The sealing element 43 is rigid, for example, made of rigid polymer plastic. As shown in Figures 5 to 13, the gap between the sealing element 43 and the second housing 41 after assembly is sealed by a sealing ring, such as an O-ring.

[0195] As shown in Figures 5 to 13, a receiving cavity 450 is defined within the second housing 41 for receiving the second module 420 of the reservoir 40. The receiving cavity 450 is defined between the closure element 140 and the distal end 120 of the second housing 41. The receiving cavity 450 is open on the side facing the distal end 120, thereby allowing the second module 420 of the reservoir 40 to be received or joined into the second housing 41 from the side of the distal end 120, and then assembled with the first module 410, as shown by arrow P2 in Figure 8, for example. A first guide structure 416, such as a notch, is also arranged on the second housing 41, and a second guide structure 466 is arranged on the second module 420; when the second module 420 is received or joined into the second housing 41, the first guide structure 416 and the second guide structure 466 cooperate to provide guidance during the assembly of the second module 420 and the first module 410.

[0196] As shown in Figures 5 to 13, at least one or more liquid outlet connectors 431 extending toward the distal end 120 are arranged on the closure element 43; the at least one or more liquid outlet connectors 431 are substantially located within the receiving cavity 450; the liquid outlet connectors 431 are hollow tubular, and the interior of the liquid outlet connectors 431 surrounds or defines a liquid outlet channel. The liquid outlet connectors 431 have a free end located in the receiving cavity 450 or toward the distal end 120, and the free end is closed. The liquid outlet connectors 431 have sidewalls or side surfaces extending longitudinally to the free end, and have liquid outlets 432 located on the sidewalls or side surfaces for the outflow of liquid matrix. In some embodiments, the diameter or width of the liquid outlet 432 can limit the outflow of a large amount of liquid matrix and allow the liquid matrix to flow out only at a predetermined rate. In a specific embodiment, the diameter or width of the liquid outlet 432 is between 0.5 and 1.5 mm; in a more specific embodiment, the diameter or width of the liquid outlet 432 is 0.8 mm. The liquid outlet 432 is arranged near the free end of the liquid outlet connector 431.

[0197] As shown in Figures 5 to 13, the first module 410 of the reservoir 40 further includes:

[0198] A deformable sealing valve 44 is mounted or arranged on and held by a sealing element 43. The sealing valve 44 is substantially annular in shape; it has a sealing portion 441 arranged perpendicular to the axial direction; the sealing portion 441 is provided with slits or cutouts 442, etc., to make it deformable, thereby allowing the venting connector 462 of the second module 420 to pass through the sealing portion 441 into the second liquid storage chamber 42. Furthermore, when the venting connector 462 of the second module 420 passes through the sealing portion 441 into the second liquid storage chamber 42, the sealing valve 44 provides a seal between the venting connector 462 of the second module 420 and the sealing element 43. And, when the venting connector 462 of the second module 420 is removed from the second liquid storage chamber 42, the sealing portion 441 can return to the initial state shown in FIG. 9, thereby closing the air communication between the second liquid storage chamber 42 and the venting connector 462. As shown in Figure 9, the slit or cut 442 on the sealing part 441 is a cross shape.

[0199] As shown in Figures 5 to 13, the second module 420 of the reservoir 40 includes:

[0200] The rigid base 46 is hollow inside; when the second module 420 is assembled or combined with the first module 410, the base 46 extends from the distal end 120 into the second housing 41 of the first module 410 and closes the opening of the receiving cavity 450 toward the distal end 120.

[0201] As shown in Figures 5 to 13, a liquid buffer chamber 461 is arranged within the base 46 to buffer or store the liquid matrix flowing out from the second liquid storage chamber 42 of the first module 410. The side of the liquid buffer chamber 461 facing the proximal end 110 is open and is shielded or closed by a flexible third sealing element 45 arranged on the base 46. The flexible third sealing element 45 is provided with a insertion hole 451 through which a liquid output connector 431 passes into the liquid buffer chamber 461. When the second module 420 is assembled or combined with the first module 410, the liquid output connector 431 passes through the insertion hole 451 of the third sealing element 45 into the liquid buffer chamber 461. Furthermore, when the second module 420 is assembled or combined with the first module 410, the flexible third sealing element 45 elastically abuts against the base 46 and the sealing element 43, thereby providing a seal between them. On the one hand, the liquid buffer chamber 461 buffers a certain amount of liquid matrix, shortening the path length for the liquid matrix to be replenished from the second liquid storage chamber 42 to the first liquid storage chamber. This is more advantageous when the liquid matrix in the first liquid storage chamber is scarce, allowing for faster replenishment. On the other hand, the liquid buffer chamber 461 maintains a certain hydraulic pressure by buffering a certain amount of liquid matrix, which helps to balance the delivery rate of the liquid matrix between the second liquid storage chamber 42 and the first liquid storage chamber, ensuring that the delivery of the liquid matrix is ​​neither too rapid nor too slow.

[0202] As shown in Figures 5 to 13, the outer diameter and / or inner diameter of the liquid output connector 431 gradually decreases, which is advantageous for inserting the liquid output connector 431 into the insertion hole 451; specifically, the outer diameter and / or inner diameter of the liquid output connector 431 gradually decreases in the direction close to the free end.

[0203] As shown in Figures 5 to 13, a removable injection plug 49 is also arranged on the side of the base 46 facing the distal end 120; when the injection plug 49 is removed, the injection port is opened to allow the liquid matrix to be filled into the liquid buffer chamber 461 through the injection port by an injection device such as an injector. As shown in Figures 5 to 13, the insertion hole 451 and the injection plug 49 / injection port are arranged opposite each other in the longitudinal direction of the second module 420 and are substantially longitudinally aligned.

[0204] As shown in Figures 5 to 13, the second module 420 of the reservoir 40 includes:

[0205] The first connection port 481 and the second connection port 482 are arranged facing the first side 130; the first connection port 481 and the second connection port 482 are arranged at intervals in the longitudinal direction. When the liquid reservoir 40 is attached to the atomizing body 30, the first connector 1161 of the atomizing body 31 is inserted into the first connection port 481, and the second connector 1162 is inserted into the second connection port 482.

[0206] As shown in Figures 5 to 13, the first connection port 481 and the second connection port 482 are defined by a flexible fourth sealing element 48 housed or arranged within the base 46 for providing a seal when the reservoir 40 is attached to the atomizing body 30.

[0207] As shown in Figures 5 to 13, a liquid connection channel 4611 is defined within the base 46 between the second connection port 482 and the liquid buffer chamber 461, thereby enabling liquid communication between the second connection port 482 and the liquid buffer chamber 461. When the reservoir 40 is attached to the atomizing body 30, the liquid connection channel 4611 provides at least a partial liquid connection between the second connector 1162 and the liquid buffer chamber 461. For example, as indicated by arrow R32 in Figure 10, the liquid matrix in the second reservoir 42 is first output from the liquid outlet 432 of the liquid output connector 431 to the liquid buffer chamber 461, and then delivered to the second connection port 482 via the liquid connection channel 4611. In use, the second connection port 482 serves as a liquid output interface for outputting or replenishing the liquid matrix from the reservoir 40 / second reservoir 42 to the first reservoir / atomizing body.

[0208] As shown in Figures 5 through 13, the second module 420 is further provided with a venting connector 462 extending from the base 46 toward the proximal end 110; the venting connector 462 is protruding relative to the rest of the second module 420. The venting connector 462 passes through a flexible third sealing element 45. The venting connector 462 is a hollow tube. Correspondingly, the fourth sealing element 48 also defines a venting passage 483 communicating between the venting connector 462 and the first connection port 481. When the reservoir 40 is attached to the atomizing body 30, air communication between the first connector 1161 and the venting connector 462 is provided at least partially by the venting passage 483. For example, as shown by arrow R41 in Figure 10, when the reservoir 40 is attached to the atomizing body 30, the air in the first reservoir / capillary element 34 flows into the first connection port 481 through the first connector 1161, and then is delivered to the air exchange connector 462 through the air exchange channel 483, and finally escapes into the second reservoir 42 in the form of bubbles to relieve or balance the pressure in the second reservoir 42.

[0209] As shown in Figures 5 to 13, a flexible covering element 17 is also arranged on the second module 420, covering at least a portion of the surface of the base 46 facing the first side 130; and when the reservoir 40 is attached to the atomizing body 30, the covering element 17 provides a seal between them at least partially. The covering element 17 is provided with a clearance opening 471 through which the first connection port 481 is exposed, allowing the first connector 1161 to pass through the clearance opening 471 into the second module 420 to align and connect with the first connection port 481. Similarly, the second connection port 482 is exposed through the clearance opening 471, allowing the second connector 1162 to pass through the clearance opening 471 into the second module 420 to align and connect with the second connection port 482.

[0210] As shown in Figures 5 to 13, a window 415 is also arranged on the second housing 41 of the first module 410; when the second module 420 is accommodated or combined within the first module 410, the covering element 17 extends out of the window 415 and is thus exposed, thereby allowing the first connector 1161 and the second connector 1162 to extend into the second module 420 for connection.

[0211] In Figures 5 to 13, when the second module 420 and the first module 410 are assembled longitudinally, there is no tight mechanical connection between them; thus, after assembly, the second module 420 and the first module 410 can move or separate longitudinally relative to each other.

[0212] As shown in Figures 4, 12, and 13, when the reservoir 40 is attached to the atomizing body 30, the first connector 1161 and the second connector 1162 extend into and connect to the second module 420, making the second module 420 immovable from the atomizing body 30 in the longitudinal direction. The first module 410, however, can be moved longitudinally relative to the atomizing body 30 between a first position and a second position by user operation. During movement, the first module 410 is limited by the cooperation of the first connecting structure 312 and the second connecting structure 411 at the first and / or second positions. Similarly, during movement, the first module 410 is also limited by the cooperation of the first positioning structure 313 and the second positioning structure 413 at the first and / or second positions.

[0213] As shown in Figures 4, 12, and 13, when the reservoir 40 is attached to the atomizing body 30, the first module 410 can be moved by the user between a first position and a second position relative to the atomizing body 30 via the operating part 418. In Figure 4, the first module 410 is in the first position, and in Figures 12 and 13, the first module 410 is in the second position. Specifically, the user moves the operating part 418 along the proximal end 110, as shown by arrow P3 in Figure 10, thereby moving the first module 410 from the first position in Figure 4 to the second position in Figures 12 and 13.

[0214] In the first position, the sealing element 43 and the flexible third sealing element 45 are longitudinally abutted and fitted; and the liquid output connector 431 passes through the insertion hole 451 of the third sealing element 45, and the liquid output connector 431 extends at least partially into the liquid buffer chamber 461, thereby enabling liquid communication between the second liquid storage chamber 42 and the liquid buffer chamber 461 / first liquid storage chamber; at this time, the liquid matrix in the second liquid storage chamber 42 can be replenished to the liquid buffer chamber 461 via the liquid outlet 432 of the liquid output connector 431, and finally replenished to the first liquid storage chamber. In the second position, the sealing element 43 and the flexible third sealing element 45 are longitudinally separated and have a distance d1; and the liquid outlet 432 of the liquid output connector 431 is located within the insertion hole 451 of the third sealing element 45; and the liquid outlet 432 is located within the sealing area defined between the first sealing rib 4511 and the second sealing rib 4512 on the inner surface of the insertion hole 451, so that the liquid outlet 432 is closed or shut off. At this time, the liquid matrix in the second liquid storage chamber 42 cannot be replenished to the liquid buffer chamber 461 / first liquid storage chamber.

[0215] In the first position, the venting connector 462 of the second module 420 passes through the sealing part 441 of the sealing valve 44 of the first module 410 and extends into the second liquid storage chamber 42, thereby making the second liquid storage chamber 42 and the first liquid storage chamber / capillary element 34 in air communication, so as to allow the air in the first liquid storage chamber / capillary element 34 to enter the second liquid storage chamber 42 to relieve or balance the pressure difference between the first liquid storage chamber and the second liquid storage chamber 42. In the second position, the ventilation connector 462 of the second module 420 extends into the sealing valve 44 but does not penetrate the sealing part 441. The sealing part 441 of the sealing valve 44 then abuts against the free end of the ventilation connector 462 to close the air communication between the ventilation connector 462 and the second liquid storage chamber 42. At this time, the second liquid storage chamber 42 and the first liquid storage chamber / capillary element 34 are not in air communication to prevent air from the first liquid storage chamber / capillary element 34 from entering the second liquid storage chamber 42 to alleviate or balance their pressure difference.

[0216] As shown in Figures 4, 12, and 13, in the first position, the surface of the second housing 41 of the first module 410 at its proximal end 110 is flush with the surface of the first housing 31 of the atomizing body 30. In the second position, the surface of the second housing 41 of the first module 410 protrudes further at its proximal end 110 than in the first position, thus forming a non-flat contact with the surface of the first housing 31 of the atomizing body 30.

[0217] In some embodiments, the first module 410 and the second module 420 of the reservoir 40 are movable relative to each other between a first position and a second position. Furthermore, a connecting or retaining structure is arranged between the first module 410 and the second module 420, such as a groove or snap-fit ​​structure, etc., arranged between the first module 410 and the second module 420; the connecting or retaining structure is used to provide connection, retention, or limitation for the first module 410 and the second module 420 of the reservoir 40 in the first and second positions.

[0218] In some embodiments, such as as shown in FIG5, when the first module 410 and the second module 420 of the reservoir 40 are in a first position or in a second position, the reservoir 40 can be attached to or detached from the atomizing body 30 along the width direction.

[0219] In some embodiments, for example, before sale or consumer use, the first module 410 and the second module 420 of the reservoir 40 are pre-assembled in a first position and then packaged or sold; during product sales, production, or packaging, a sealing plug or sealing film or other sealing component or sealing structure is arranged at the clearance opening 471 on the covering element 17 to close and seal the clearance opening 471. When used by the consumer, the sealing plug or sealing film or other sealing component or sealing structure is removed or torn off, thereby reattaching the reservoir 40 to the atomizing body 30.

[0220] For example, in some embodiments, the first module 410 and the second module 420 of the reservoir 40 are pre-assembled in the second position before being packaged or sold, for instance, before being sold or used by the consumer; in this case, the second reservoir 42 is closed, and the above-mentioned sealing plug or sealing film or other sealing components may not be arranged at the clearance opening 471 on the covering element 17. Of course, sealing plugs or sealing films or other sealing components can also be arranged in the same way to achieve multiple seals.

[0221] Figures 14 to 23 show schematic diagrams of an electronic atomizing device according to another embodiment; in this embodiment, the electronic atomizing device includes: an atomizing body 200a and a liquid reservoir 100a; the atomizing body 200a and the liquid reservoir 100a can each exist independently, while also being combined with each other.

[0222] In one embodiment, the reservoir 100a can store more liquid matrix than the atomizing body 200a for replenishing the liquid matrix to the atomizing body 200a during use. The atomizing body 200a can store a relatively small amount of liquid matrix and atomize the liquid matrix to produce an aerosol. Before the reservoir 100a and the atomizing body 200a are combined, they exist independently of each other; and after the reservoir 100a is combined with the atomizing body 200a, they together define a complete electronic atomization device for use or inhalation of aerosol by a user.

[0223] In some embodiments, when the reservoir 100a and the atomizing body 200a exist separately or independently, they cannot be used or inhaled independently by the user. For example, as shown in Figures 1 to 4, the reservoir 100a at least partially defines the mouthpiece for user use or inhalation; the atomizing body 200a atomizes the liquid matrix to produce an aerosol. When the reservoir 100a is removed or separated from the atomizing body 200a, the reservoir 100a cannot atomize the liquid matrix to produce an aerosol independently, and the atomizing body 200a cannot be inhaled independently by the user. In some embodiments, the reservoir 100a and the atomizing body 200a can only be used by the user when combined to define a complete electronic atomization device, and are recycled as a whole after the liquid matrix inside them is consumed.

[0224] Alternatively, in some other embodiments, the atomizing body 200a is used to atomize a liquid matrix to generate an aerosol; the reservoir 100a is removably attached to the atomizing body 200a; the reservoir 100a is used as a consumable and thus can be replaced, and the atomizing body 200a is reusable; when the liquid matrix in the reservoir 100a is consumed, the user can remove and replace the reservoir 100a from the atomizing body 200a with a new one.

[0225] As shown in Figures 14 to 23, the atomizing body 200a includes:

[0226] The first end 210a and the second end 220a are opposite to each other in the longitudinal direction;

[0227] The receiving cavity 211a is located near the first end 210a and is open at the first end 210a; thus, when the reservoir 100a is received by the atomizing body 200a, the receiving cavity 211a is used to receive a portion of the reservoir 100a.

[0228] The partition wall 214a is arranged perpendicular to the longitudinal direction; and the partition wall 214a divides and defines at least a portion of the space within the atomizing body 200a to form a receiving cavity 211a; when the liquid reservoir 100a is received in the receiving cavity 211a of the atomizing body 200a, the liquid reservoir 100a at least partially abuts against the partition wall 214a to provide support.

[0229] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0230] The bracket 240a is used to house, support, or retain the various functional components used for liquid matrix atomization. As shown in Figures 14 to 23, the bracket 240a is securely installed or retained within the atomizing body 200a by means of riveting or snap-fitting; for example, the bracket 240a is connected to the partition wall 214a by snap-fitting.

[0231] As shown in Figures 14 to 23, the support 240a is annular in shape, and the following are defined or arranged within the support 240a:

[0232] The first liquid storage chamber is defined by a portion of the space within the support 240a; the first liquid storage chamber forms a liquid matrix storage space located in the atomizing body 200a for storing the liquid matrix;

[0233] The liquid holding element 271a is made of a flexible or rigid porous material or fibrous material to adsorb and retain the liquid matrix stored in the first liquid storage chamber; the liquid holding element 271a and / or the first liquid storage chamber are substantially annular in shape. In some embodiments, the liquid holding element 271a may also be made of a rigid porous material such as porous ceramic or porous glass, or may also be made of flexible porous fibers such as porous cotton fibers, porous nonwoven fabric or porous sponge.

[0234] As shown in Figures 14 to 23, the bracket 240a contains:

[0235] A tubular element 260a is housed or held within a support 240a; the tubular element 260a extends axially along the support 240a; the tubular element 260a penetrates the liquid holding element 271a; after assembly, a portion of the upper end of the tubular element 260a is tightly fitted to the support 240a by means of riveting or interference fitting, and thus fixed.

[0236] The atomizing assembly is located within the tubular element 260a and is in fluid communication with the liquid holding element 271a and / or the first liquid storage chamber, thereby being used to draw in a liquid matrix and atomize it to generate an aerosol; as shown in Figures 14 to 23, the atomizing assembly includes: a liquid guiding element 270a and a heating element 280a combined with the liquid guiding element 270a.

[0237] In some embodiments, the liquid guiding element 270a is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the liquid guiding element 270a is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the support 240a; the liquid guiding element 270a is coaxial with the liquid holding element 271a and / or the tubular element 260a, and is located within the liquid holding element 271a and / or the tubular element 260a. Alternatively, in some other variations, the liquid guiding element 270a may also include a rigid porous element, such as porous ceramic or porous glass. The outer surface of the liquid guiding element 270a is in fluid communication with the liquid holding element 271a and / or the first liquid reservoir, thereby allowing the outer surface of the liquid guiding element 270a to draw liquid matrix from the liquid holding element 271a and / or the first liquid reservoir, as shown by arrow R2 in FIG22.

[0238] In some embodiments, the liquid guiding element 270a is surrounded and held by the liquid holding element 271a, and contacts the liquid holding element 271a to form fluid communication. Alternatively, in some other embodiments, the liquid guiding element 270a is held within a tubular element 260a, which has a plurality of liquid perforations; the liquid guiding element 270a draws liquid matrix from the liquid holding element 271a and / or the first liquid reservoir through the liquid perforations on the tubular element 260a.

[0239] In some alternative embodiments, the heating element 280a is a resistance heating mesh, a resistance heating coil, etc. In this embodiment, the heating element 280a is a heating element wound from a sheet-like or mesh-like substrate.

[0240] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0241] Battery cell 230a is used for power supply; battery cell 230a is arranged between bracket 240a and second end 220a.

[0242] A circuit board (not shown), such as a PCB or FPC board, is arranged between the bracket 240a and the second end 220a for controlling the supply of power to the heating element 280a. In some embodiments, the heating element 280a is connected to the circuit board by soldering conductive leads, thereby electrically connecting to the circuit board.

[0243] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0244] The flexible base 340a is at least partially located within the support 240a, thereby closing the opening of the support 240a and / or the first liquid reservoir 324 toward the second end 220a, and supporting the liquid holding element 271a and the tubular element 260a.

[0245] Specifically, the base 340a is provided with a insertion slot for inserting and installing the tubular element 260a; after assembly, the lower end of the tubular element 260a is inserted into the insertion slot of the base 340a for installation and fixation. After assembly, the liquid holding element 271a and / or the tubular element 260a are longitudinally clamped or held between the bracket 240a and the base 340a.

[0246] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0247] An air inlet 221a, located at the second end 220a, is used to allow outside air to enter during suction.

[0248] The air intake channel, defined by multiple components or assembly gaps between components, provides a flow path for delivering air entering through the air intake 221a to the atomizing assembly. As shown by arrow R1 in Figure 20, the air intake channel is at least partially formed or defined between the battery cell 230a and the housing of the atomizing body 200a.

[0249] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0250] An airflow sensor 320a is connected to the airflow in the intake channel and is used to sense changes in airflow through the intake channel when the user inhales. In an embodiment, the airflow sensor 320a is mounted or held between the base 340a and the battery cell 230a.

[0251] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0252] An annular support element 290a extends at least partially from the second end of the tubular element 260a into the tubular element 260a and at least partially supports the tubular element 260a. In some embodiments, the support element 290a is annular in shape and has a plurality of circumferentially spaced wire grooves arranged on its outer surface. During assembly, the two conductive leads connected to the heating element 280a are respectively confined in the wire grooves to form isolation, thereby preventing problems such as short circuits caused by the two conductive leads connected to the heating element 280a coming into contact with each other during assembly.

[0253] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0254] At least one or more liquid inlet connectors 241a extend from the support 240a into the receiving cavity 211a; and the free end of the liquid inlet connector 241a is located and exposed within the receiving cavity 211a. The liquid inlet connector 241a is arranged to extend longitudinally; and the liquid inlet connector 241a penetrates the partition wall 214a. The liquid inlet connector 241a is a hollow tube with a closed free end; a liquid inlet 2411a is arranged on the sidewall or outer surface of the liquid inlet connector 241a for allowing the liquid matrix to enter. When the reservoir 100a is received in the receiving cavity 211a, the liquid inlet connector 241a can be inserted into the reservoir 100a, thereby establishing fluid communication with the reservoir 100a, so that the liquid matrix in the reservoir 100a is replenished to the first reservoir / liquid holding element 271a via the liquid inlet connector 241a.

[0255] In some embodiments, the number of liquid inlets 2411a on each liquid inlet connector 241a is at least two; the at least two liquid inlets 2411a are arranged radially opposite to each other on the liquid inlet connector 241a.

[0256] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0257] At least one or more capillary elements 250a are filled or arranged within the liquid inlet connector 241a and extend from the liquid holding element 271a to the liquid inlet 2411a, thereby providing liquid transfer between the liquid inlet 2411a and the liquid holding element 271a. This allows the liquid matrix entering from the liquid inlet 2411a to be transferred or replenished to the liquid holding element 271a / first reservoir via capillary action of the capillary elements 250a.

[0258] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0259] Flexible first sealing element 242a and second sealing element 243a, such as O-rings, are longitudinally spaced on and around the liquid inlet connector 241a. A liquid inlet 2411a is located between the first sealing element 242a and the second sealing element 243a. The first sealing element 242a and the second sealing element 243a are located within and exposed in the receiving cavity 211a.

[0260] As shown in Figures 14 to 23, the atomizing body 200a also includes:

[0261] A flexible third sealing element 244a, such as an O-ring, is installed or retained between the liquid inlet connector 241a and the partition wall 214a to provide a seal between them.

[0262] As shown in Figures 14 to 23, a flexible covering element 245a is also arranged on the support 240a, forming or being attached to the surface of the support 240a facing the receiving cavity 211a. The covering element 245a is located between the two liquid inlet connectors 241a and surrounds or defines an endotracheal inlet 2451a for insertion of the aerosol outlet tube 112a of the reservoir 100a.

[0263] As shown in Figures 14 to 23, the reservoir 100a includes several components disposed within a second housing 10a (which may be referred to as the housing). The second housing 10a may contain one or more reusable components; the second housing 10a has a proximal end 110a and a distal end 120a opposite each other in the longitudinal direction; in use, the proximal end 110a is the end closer to the user for aspiration; the distal end 120a is the end farther from the user; in some examples, all or only part of the second housing 10a may be formed of a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, etc.

[0264] As shown in Figures 14 to 23, the side of the second housing 10a facing the distal end 120a is open and is provided with a removable end cap 20a to close the opening of the second housing 10a facing the distal end 120a.

[0265] As shown in Figures 14 to 23, when the reservoir 100a is received in the atomizing body 200a during use, the second housing 10a partially extends into the receiving cavity 211a of the atomizing body 200a, and partially lies outside the receiving cavity 211a of the atomizing body 200a; this is advantageous for the user to move the reservoir 100a relative to the atomizing body 200a by operating the exposed part of the second housing 10a with their fingers.

[0266] As shown in Figures 14 to 23, the reservoir 100a further includes:

[0267] The air outlet 111a is located near the proximal end 110a and is used for user suction.

[0268] An aerosol output tube 112a extends from an outlet 111a toward a distal end 120a for delivering aerosol to the outlet 111a; in an embodiment, the aerosol output tube 111 is integrally molded with the second housing 10a.

[0269] A second liquid storage chamber 42a is used to store a liquid matrix; at least a portion of the second liquid storage chamber 42a is defined between the aerosol output tube 112a and the second housing 10a. The side of the second liquid storage chamber 42a near the proximal end 110a is closed, and the boundary of the second liquid storage chamber 42a facing the distal end 120a is closed or defined by a sealing element 43a. In use, the liquid matrix within the second liquid storage chamber 42a exits from the sealing element 43a. In some embodiments, the second liquid storage chamber 42a is primarily defined between the second housing 10a and the aerosol output tube 112a.

[0270] As shown in Figures 14 to 23, the reservoir 100a further includes:

[0271] A sealing element 43a, arranged substantially perpendicular to the longitudinal direction of the reservoir 100a, is used to close the opening of the second reservoir 42a toward the distal end 120a. After assembly, the sealing element 43a is covered by the end cap 20a. The sealing element 43a has at least one or more liquid outlet ports 431a arranged through the end cap 20a and extending to the distal end 120a. In this embodiment, the distal end 120a is terminated by and defined by at least one or more liquid outlet ports 431a.

[0272] In this embodiment, the liquid output interface 431a is a hollow tubular shape. The interior of the liquid output interface 431a surrounds or defines a liquid output channel 432a; the liquid output channel 432a serves to provide a pathway for the liquid matrix within the second reservoir 42a to exit or be output.

[0273] As shown in Figures 14 to 23, after assembly, the aerosol output tube 112a passes at least partially through the sealing element 43a and the end cap 20a, and is at least partially exposed outside the end cap 20a, thereby facilitating connection to the air tube connector 2451a on the atomizing body 200a.

[0274] As shown in Figures 14 to 23, the reservoir 100a further includes:

[0275] A flexible fourth sealing element 44a is at least partially disposed between the sealing element 43a and the second housing 10a to provide a seal between them. Additionally, at least a portion of the fourth sealing element 44a is also positioned between the sealing element 43a and the aerosol outlet tube 112a to provide a seal between them.

[0276] As shown in Figures 20 to 23, when the reservoir 100a is attached to or received in the receiving cavity 211a, it can move longitudinally between a first position and a second position relative to the atomizing body 100a.

[0277] The second housing 10a has a first locking protrusion 11a and a second locking protrusion 12a arranged longitudinally on its surface; the receiving cavity 211a has a first locking groove 212a and a second locking groove 213a arranged longitudinally on its inner surface.

[0278] As shown in Figure 20, the reservoir 100a is in a first position relative to the atomizing body 200a; in the first position, the first locking protrusion 11a extends into the first locking groove 212a, and the second locking protrusion 12a extends into the second locking groove 213a, thereby keeping the reservoir 100a stably in the first position.

[0279] As shown in Figure 22, the reservoir 100a is in a second position relative to the atomizing body 200a. In the second position, the first latching protrusion 11a extends into the second latching groove 213a, and the second latching protrusion 12a is located in the receiving cavity 211a and is in a non-connected structure, thereby making the reservoir 100a stably maintained in the second position.

[0280] As shown in Figures 20 to 23, in the first position, the end cap 20 of the reservoir 100a abuts against the inner bottom wall / partition wall 214a of the receiving cavity 211a. In the second position, the reservoir 100a has a gap d11 between the end cap 20 and the inner bottom wall / partition wall 214a of the receiving cavity 211a.

[0281] As shown in Figures 20 and 21, in the first position, the liquid input connector 241a of the atomizing body 200a passes through the liquid output interface 431a and extends at least partially into the second liquid storage chamber 42a. As shown in Figures 20 and 21, the liquid inlet 2411a on the liquid input connector 241a extends at least partially into the second liquid storage chamber 42a, thus achieving fluid communication with the second liquid storage chamber 42a. At this time, the first sealing element 242a also passes through the liquid output interface 431a and extends into the second liquid storage chamber 42a. In this first position, the liquid matrix of the second liquid storage chamber 42a can flow from the liquid inlet 2411a into the liquid input connector 241a, and then be absorbed by the capillary element 250a and transferred to the first liquid storage chamber / liquid holding element 271a, as indicated by arrow R2 in Figures 20 and 21.

[0282] In this first position, the reservoir 100a and the atomizing body 200a together define the airflow channel of the electronic atomizing device. The airflow channel provides a flow path from the air inlet 221a through the atomizing component / heating element 280a to the air outlet 111a, so as to output the aerosol generated by the atomizing component / heating element 280a to the air outlet 111a. In the embodiment, the airflow path of the complete airflow channel is shown by arrow R1 in FIG20. The air entering from the air inlet 221a passes through the air inlet channel to the atomizing component / heating element 280a, and carries the aerosol generated by the heating element 280a through the air tube inlet 2451a of the sealing element 310 and enters the aerosol output tube 112a, and finally outputs to the air outlet 111a for inhalation by the user.

[0283] As shown in Figures 22 and 23, the user moves the second housing 10a, specifically by pulling, as indicated by arrow P12 in Figure 22, thereby moving the reservoir 100a from the first position in Figures 20 and 21 to the second position in Figures 22 and 23. In the second position, the liquid inlet connector 241a of the atomizing body 200a extends only into the liquid outlet port 431a and not into the second reservoir chamber 42a. As shown in Figures 22 and 23, the first sealing element 242a and the second sealing element 243a on the liquid inlet connector 241a elastically abut against the inner surface of the liquid outlet port 431a to form a seal, thereby closing the liquid inlet 2411a. At this time, the liquid matrix in the second reservoir chamber 42a cannot be replenished to the atomizing body 200a through the liquid inlet 2411a.

[0284] As shown in Figures 14 to 23, the atomizing body 200a has at least two liquid inlet connectors 241a, which may include a first connector and a second connector arranged side by side. Correspondingly, the reservoir 100a also has at least two liquid outlet ports 431a, which may include a first port and a second port arranged side by side. The first connector and the second connector are respectively arranged on both sides of the atomizing assembly, and the first port and the second port are respectively arranged on both sides of the atomizing assembly. In some embodiments, the free ends of the first connector and the second connector are flush. Furthermore, the distance between the liquid inlet 2411a on the first connector and its free end is equal to the distance between the liquid inlet 2411a on the second connector and its free end.

[0285] In use, when the liquid matrix in the second liquid storage chamber 42a of the liquid reservoir 100a flows into the first liquid storage chamber / atomizing body 200a from at least one of the liquid inlets 2411a on the plurality of liquid inlet connectors 241a, the liquid inlet 2411a of at least another liquid inlet connector 241a is used as an air inlet to provide air from the first liquid storage chamber / atomizing body 200a into the second liquid storage chamber 42a of the liquid reservoir 100a, so as to maintain the pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0286] Alternatively, in one embodiment, each liquid inlet 2411a has two liquid inlets 2411a arranged on its sidewall in a radially opposite direction; when one of the liquid inlets 2411a provides liquid matrix to replenish the first liquid storage chamber, air in the first liquid storage chamber is provided to enter the liquid storage 100a from the other liquid inlet 2411a to maintain pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0287] In a more preferred embodiment, for example as shown in Figures 14 to 23, the inner surface of the liquid inlet connector 241a is provided with:

[0288] The ventilation channel 2412a is arranged to extend longitudinally. Located between the first liquid storage chamber / liquid holding element 271a and the liquid inlet 2411a, the ventilation channel 2412a forms a ventilation passage between the capillary element 250a and the inner surface of the liquid inlet connector 241a. When the liquid matrix in the reservoir 100a is transferred to the first liquid storage chamber / liquid holding element 271a through the capillary element 250a, air in the first liquid storage chamber / liquid holding element 271a flows from the ventilation channel 2412a to the liquid inlet 2411a, and then escapes from the liquid inlet 2411a into the second liquid storage chamber 112a to balance the pressure of the second liquid storage chamber 112a and the first liquid storage chamber.

[0289] In some embodiments, the ventilation channel 2412a extends to and is connected to the liquid inlet 2411a. The ventilation channel 2412a has a depth of approximately 0.5 to 2.0 mm and a width of approximately 0.5 to 2.0 mm.

[0290] In this embodiment, the ventilation channel provided by the ventilation slot 2412a allows air exchange between the first liquid storage chamber and the second liquid storage chamber 42a to bypass the liquid matrix transmitted by the capillary element 250, which is beneficial for maintaining unobstructed ventilation.

[0291] In some embodiments, the first liquid storage cavity is further defined by a plurality of spacers, such as the spacer between the base 340a and the lower surface of the liquid holding element 271a, the spacer between the outer surface of the liquid holding element 271a and the inner surface of the support 240a, or the spacer between the upper surface of the liquid holding element 271a and the support 240a.

[0292] Specifically, the support 240a is also provided with an annular protrusion 2413a extending from the liquid inlet connector 241a toward the first liquid storage chamber. The upper surface of the liquid holding element 271a abuts against the annular protrusion 2413a, so that the ventilation channel can only communicate with the airflow of the first liquid storage chamber through the micropores in the portion of the liquid holding element 271a near the upper surface, thereby preventing or avoiding the air in the liquid inlet connector 241a from directly communicating with the outside air through the gap or opening between the liquid holding element 330 and the support 240a. When the liquid matrix in the first liquid storage chamber is consumed, the portion of the liquid holding element 271a near the upper surface is without liquid matrix. The porous structure in this portion provides a channel for transmitting negative pressure between the liquid inlet connector 241a and the first liquid storage chamber, so that the liquid inlet connector 241a can maintain balance with the negative pressure or pressure in the first liquid storage chamber.

[0293] In some embodiments, in the first position, when the liquid matrix absorbed and held by the liquid holding element 271a in the first reservoir is consumed, causing the negative pressure in the first reservoir to exceed a predetermined threshold, the reservoir 100a replenishes the first reservoir with liquid matrix under the drive of the negative pressure, as shown by arrow R2 in FIG21. When a predetermined amount of liquid matrix is ​​replenished into the first reservoir, causing the negative pressure in the first reservoir to fall below the predetermined threshold again, the pressure difference between the first reservoir and the second reservoir 42a reaches equilibrium, preventing further replenishment of liquid matrix into the first reservoir. Therefore, in use, the liquid matrix can be replenished to the first reservoir only in a predetermined amount each time, depending on the user's inhalation or usage control. Specifically, the electronic atomizing device can respond to the user's inhalation and automatically replenish the liquid matrix in the reservoir 100a to the atomizing body 200a in a predetermined amount during each inhalation or during the lag period after inhalation.

[0294] In some embodiments, in the first position, a gap exists between the outer surface of the liquid inlet connector 241a and the inner surface of the liquid outlet connector 431a, defining a capillary channel between the liquid inlet connector 241a and the liquid outlet connector 431a. This capillary channel adsorbs and retains the liquid matrix flowing from the liquid outlet connector 431a, preventing excessive replenishment of the liquid matrix from the second reservoir 42a into the liquid inlet connector 241a. In use, the capillary channel allows for controlled replenishment of the liquid matrix from the second reservoir 42a into the first reservoir by a predetermined amount through capillary action, which is advantageous for preventing oversaturation of the liquid matrix within the first reservoir. Specifically, in use, the liquid matrix within the capillary channel forms a liquid film to seal the liquid inlet 2411a of the liquid inlet connector 241a, thereby preventing excessive replenishment of the liquid matrix into the first reservoir.

[0295] In this embodiment, the volume of the first liquid storage chamber is smaller than the volume of the second liquid storage chamber 42 / 42a. The amount of liquid matrix that the second liquid storage chamber 42 / 42a can absorb and store is greater than the amount of liquid matrix that the first liquid storage chamber can absorb and store. For example, in some specific embodiments, the second liquid storage chamber 42 / 42a can absorb and store 5 to 20 mL of liquid matrix, more specifically, for example, 10 mL; the first liquid storage chamber can store 5 to 20 mL of 0.5 to 3 mL of liquid matrix, more specifically, for example, 2 mL.

[0296] 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.
