[0030] This application provides an atomizer that can solve the problem of liquid leakage caused by improper placement of the atomizer, such as when it is placed upside down or flat, or alleviate the situation where the user inhales liquid matrix during vaping. (See also...) Figures 1-4 , Figure 1 This is a cross-sectional schematic diagram of an atomizer according to one or more embodiments of this application; Figure 2 This is a cross-sectional schematic diagram of the first housing according to one or more embodiments of this application; Figure 3 This is a cross-sectional schematic diagram of the exploded structure of the first shell and the first tube according to one or more embodiments of this application; Figure 4 This is a cross-sectional schematic diagram of the first housing and the first tube body according to one or more embodiments of this application. The atomizer 100 provided in this application includes a first housing, an atomizing core 130, a liquid storage component 140, and a first tube body 120.

[0031] The first housing includes a cavity portion 112 and a base 111 connected to the cavity portion 112. The cavity portion 112 forms a chamber 113 for storing a liquid matrix (not shown). An atomizing core 130 is disposed within the cavity portion 112 for atomizing the liquid matrix to generate an aerosol. A liquid storage element 140 is disposed within the cavity portion 112 and around the atomizing core 130. The liquid storage element 140 absorbs the liquid matrix in the chamber 113 and guides at least a portion of the absorbed liquid matrix to the atomizing core 130. A first tube 120 is disposed within the base 111 and communicates with the atomizing core 130 to discharge the aerosol. A collection chamber 116 is provided between the base 111 and the outer wall of the first tube 120. The collection chamber 116 communicates with the liquid storage element 140 to collect liquid matrix leaking through the liquid storage element 140.

[0032] Understandably, the liquid storage device 140 can absorb the liquid matrix in the chamber 113. If the wettability of the liquid storage device 140 is in a supersaturated state, the liquid matrix may leak out. If the atomizer 100 is placed upside down or flat, the leaked liquid matrix can enter the collection chamber 116 connected to the liquid storage device 140, thereby avoiding the problem of liquid matrix leakage caused by the leaked liquid matrix entering the first tube 120. Furthermore, the leaked liquid matrix cannot enter the first tube 120, so the user will not draw in the liquid matrix when aspirating, which can improve the user experience.

[0033] The liquid matrix comprises tobacco-containing materials, which include volatile tobacco flavor compounds released from the liquid matrix upon heating. Alternatively or additionally, the liquid matrix may comprise non-tobacco materials. The liquid matrix may include water, ethanol or other solvents, plant extracts, nicotine solutions, and natural or artificial flavorings. Preferably, the liquid matrix further comprises an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0034] In one embodiment, the radial width of the collection chamber 116 is between 0.1 mm and 2 mm. For example, the radial width of the collection chamber 116 can be 0.1 mm, 0.5 mm, 0.9 mm, 1.1 mm, 1.6 mm, 1.9 mm, 2 mm, etc., and is not limited here. In this embodiment, the radial width of the collection chamber 116 is between 0.1 mm and 2 mm, which can prevent the liquid matrix from forming adhesion between the substrate 111 and the first tube 120, thereby ensuring that the liquid matrix can smoothly enter the collection chamber 116. At the same time, the radial width of the collection chamber 116 is not too large, so that the atomizer 100 can maintain a small size.

[0035] In one embodiment, the axial depth of the collecting chamber 116 is between 0.2 mm and 20 mm. For example, the axial depth of the collecting chamber 116 can be 0.2 mm, 0.9 mm, 1.9 mm, 5.1 mm, 6.4 mm, 7.8 mm, 20 mm, etc., and is not limited here. In this embodiment, the axial depth of the collecting chamber 116 is between 0.2 mm and 20 mm, which ensures that the collecting chamber 116 can collect more liquid matrix seeping from the liquid storage device 140, thereby improving the leakage prevention threshold of the collecting chamber 116. At the same time, the axial depth of the collecting chamber 116 is not too large, which facilitates the return of the liquid matrix in the collecting chamber 116 to the liquid storage device 140.

[0036] In one embodiment, the radial width of the collecting cavity 116 is between 0.1 mm and 2 mm, while the axial depth of the collecting cavity 116 is between 0.2 mm and 20 mm.

[0037] In one embodiment, the opening of the collection chamber 116 is disposed facing the liquid storage component 140, and the projection of the liquid storage component 140 covers the opening of the collection chamber 116. When the atomizer 100 is placed upside down or flat, the liquid matrix overflowing from the liquid storage component 140 can more easily enter the collection chamber 116, thereby accelerating the speed at which the seeping liquid matrix enters the collection chamber 116 and reducing the probability of the liquid matrix entering the first tube 120.

[0038] In one embodiment, the atomizer 100 further includes a support 160, a second tube 150, and a third tube 170.

[0039] A support 160 is connected to the cavity portion 112, and the cavity 113 is located between the base 111 and the support 160. A second tube 150 is sleeved around the liquid storage component 140, with one end of the second tube 150 connected to the base 111 and the other end connected to the support 160. A through hole is provided on the second tube 150, through which the liquid storage component 140 absorbs the liquid matrix in the cavity 113. A third tube 170 is disposed inside the liquid storage component 140 and can guide the aerosol flow to the first tube 120.

[0040] It is understood that the second tube 150 and the third tube 170 are spaced apart, and the liquid reservoir 140 is held in the space between the second tube 150 and the third tube 170. The liquid matrix can surround the second tube 150 and thus be stored in the receiving chamber 113. The atomizing core 130 can be connected to the third tube 170 or can be embedded inside the third tube 170. The liquid matrix in the liquid reservoir 140 can pass through the gap between the third tube 170 and the atomizing core 130 or can pass through the wall of the third tube 170 to be transferred to the atomizing core 130, and then be atomized by the atomizing core 130 to produce an aerosol.

[0041] In one embodiment, the through hole is located near the support 160, which facilitates the absorption of the liquid matrix in the chamber 113 by the liquid storage component 140, thereby reducing the residue of the liquid matrix in the chamber 113.

[0042] In one embodiment, a suction nozzle 114 is provided on one side of the base 111, and a protruding tube 115 is provided on the other side. The protruding tube 115 is embedded in the second tube body 150, and the end of the protruding tube 115 abuts against the liquid storage device 140 to guide the liquid leaking from the liquid storage device 140 to the collection chamber 116. Furthermore, the axial distance a between the end of the protruding tube 115 away from the suction nozzle 114 and the end of the first tube body 120 away from the suction nozzle 114 is greater than or equal to 1 mm.

[0043] The protruding tube 115 is interference-fitted into the second tube body 150, making installation of the second tube body 150 and the base 111 simple and convenient. The inner wall of the protruding tube 115 is configured to extend to the boundary of the connecting collection chamber 116, and the inner wall of the protruding tube 115 may be flush with the boundary of the collection chamber 116, with no obvious dividing line between the inner wall of the protruding tube 115 and the boundary of the collection chamber 116. This facilitates the flow of liquid matrix leaking from the reservoir 140 from the end of the protruding tube 115 along the inner wall of the protruding tube 115 to the collection chamber 116.

[0044] The axial distance 'a' between the end of the protruding tube 115 facing away from the nozzle 114 and the end of the first tube body 120 facing away from the nozzle 114 is greater than or equal to 1 mm, such that the end of the protruding tube 115 facing away from the nozzle 114 and the end of the first tube body 120 facing away from the nozzle 114 are located on different radial planes. In other words, the radial plane containing the end of the protruding tube 115 facing away from the nozzle 114 is at least 1 mm closer to the support 160 than the radial plane containing the end of the first tube body 120 facing away from the nozzle 114. Therefore, when the end of the convex tube 115 away from the nozzle 114 abuts against the liquid storage device 140, it can prevent the end of the first tube body 120 away from the nozzle 114 from also abutting against the liquid storage device 140. This helps to form an axial gap between the end of the first tube body 120 away from the nozzle 114 and the liquid storage device 140, which in turn facilitates the entry of gas or liquid on the inner wall of the first tube body 120 into the collection chamber 116 through the axial gap between the end of the first tube body 120 away from the nozzle 114 and the liquid storage device 140.

[0045] The axial spacing a is greater than or equal to 1 mm, which can prevent the liquid matrix from sticking together between the end of the convex tube 115 away from the nozzle 114 and the end of the first tube 120 away from the nozzle 114, thereby ensuring that the gas or liquid can smoothly enter the collection chamber 116.

[0046] In one embodiment, the distance b between the end of the first tube 120 away from the nozzle 114 and the end face of the liquid storage device 140 is greater than 0.5 mm. That is, there is an axial gap between the end of the first tube 120 away from the nozzle 114 and the liquid storage device 140, which facilitates the entry of gas or liquid on the inner wall of the first tube 120 into the collection chamber 116 through the axial gap between the end of the first tube 120 away from the nozzle 114 and the liquid storage device 140.

[0047] In one embodiment, there is a gap between the third tube 170 and the first tube 120. This gap provides an inlet for the aerosol condensate in the first tube 120 to flow into the collection chamber 116 for storage, so that the collection chamber 116 can also collect the condensate formed by the aerosol. The condensate can finally flow back to the liquid storage unit 140 and be re-atomized into aerosol by the atomizing core 130, thereby improving the utilization rate of the liquid matrix and reducing the waste of the liquid matrix.

[0048] In one embodiment, the inner diameter of the third tube 170 is equal to the inner diameter of the first tube 120. This is beneficial in preventing the liquid in the collection chamber 116 from dripping down the outer wall of the first tube 120 onto the inner side of the third tube 170 and thus not being absorbed by the liquid storage device 140. It also prevents the liquid leaking from the liquid storage device 140 when the atomizer is inverted from dripping down the outer wall of the third tube 170 into the inner side of the first tube 120 or into the mouthpiece 114, and then leaking to the outside through the first tube 120 and / or the mouthpiece 114.

[0049] In one embodiment, the axial distance c between the third tube 170 and the first tube 120 is greater than 0.5 mm. Understandably, the axial distance between the third tube 170 and the first tube 120 is greater than 0.5 mm, preventing the liquid matrix from forming an adhesion between the third tube 170 and the first tube 120. This facilitates the entry of gas or liquid on the inner wall of the first tube 120 into the collection chamber 116 through the axial gap between the third tube 170 and the first tube 120.

[0050] In one embodiment, the axial distance d between the third tube 170 and the liquid storage element 140 is greater than 0.5 mm. The distance between the end face of the third tube 170 near the first tube 120 and the end face of the liquid storage element 140 near the first tube 120 is greater than 0.5 mm, or in other words, the distance by which the end of the third tube 170 near the first tube 120 protrudes from the end of the liquid storage element 140 near the first tube 120 is greater than 0.5 mm.

[0051] In one embodiment, the wall thickness of the first tube 120 is relatively thin. For example, the wall thickness of the first tube 120 is less than or equal to 0.5 mm. For example, the wall thickness of the first tube 120 can be 0.08 mm, 0.1 mm, 0.15 mm, 0.17 mm, 0.2 mm, 0.24 mm, 0.4 mm, 0.47 mm, 0.5 mm, etc.

[0052] The atomizing core 130 is an electrically heated element that releases heat to cause the liquid matrix to evaporate and generate an aerosol. The aerosol formed in the atomizing core 130 has a certain temperature. As the aerosol moves away from the atomizing core 130, the temperature of the aerosol gradually decreases. When the aerosol flows through the first tube 120, if there is a large temperature difference between the aerosol and the first tube 120, the aerosol will release a large amount of heat to the first tube 120, which will cause the aerosol to condense on the inner wall of the first tube 120 to form aerosol condensate. In this embodiment, the wall thickness of the first tube 120 is relatively thin, which allows the first tube 120 to heat up quickly after absorbing less heat. This prevents the subsequent aerosol from continuing to condense on the inner wall of the first tube 120 to form aerosol condensate, which helps to reduce the amount of condensate. When the user draws into the nozzle 114, it helps to prevent the user from drawing the condensate formed on the inner wall of the first tube 120 into their mouth. It also helps to prevent the condensate from flowing along the inner wall of the first tube 120 to the nozzle 114 and then leaking through the nozzle 114 when the atomizer is inverted.

[0053] In one embodiment, the first tube 120 includes a metal tube. Further, the first tube 120 may be made of metal. On the one hand, it is easy to process the wall of the metal tube to a very thin thickness, for example, the wall thickness of the metal tube is less than or equal to 0.1 mm; on the other hand, metal tubes are easier to heat up and have a faster heating rate compared to plastic products.

[0054] In one embodiment, the first tube 120 and the first housing are integrally formed. For example, the first tube 120 and the first housing can be integrally formed by conventional methods such as injection molding or 3D printing, and are not limited thereto.

[0055] In one embodiment, the first tube 120 is an independent tube assembled within the first housing. That is, the first tube 120 and the first housing are both independent structures, and the first tube 120 and the first housing are assembled by means of insertion, embedding, riveting, welding, bonding, etc. Of course, the first tube 120 and the first housing can also be assembled by insert injection molding.

[0056] In one embodiment, a dividing rib 117 is provided between the outer wall of the first tube 120 and the base 111, dividing the collection chamber 116 into multiple compartments. The dividing rib 117 can enhance the strength of the first tube 120, providing a certain degree of protection for the first tube 120 and reducing the probability of damage to the first tube 120. In addition, the dividing rib 117 divides the collection chamber 116 into multiple compartments, which helps to lock the liquid collected in the collection chamber 116 in the collection chamber 116, preventing the liquid collected in the collection chamber 116 from flowing out when the atomizer is laid flat.

[0057] The dividing ribs 117 can be evenly distributed on the outer side wall of the first pipe body 120, or symmetrically distributed on the outer side wall of the first pipe body 120, which is not limited here. The number of dividing ribs 117 can be 2, 3, 4, etc., which is not limited here.

[0058] In one embodiment, the first housing is provided with an exhaust port 118 and an injection port 119. The exhaust port 118 is used to discharge gas from the chamber 113, and the liquid matrix can be injected into the chamber 113 through the injection port 119. That is to say, by providing the exhaust port 118 and the injection port 119, the first housing in this embodiment allows the liquid matrix in the chamber 113 to be replenished from the outside, enabling the atomizer 100 to be reused and making the atomizer 100 more environmentally friendly.

[0059] In one embodiment, the first distance from the end of the first tube 120 facing the liquid storage device 140 to the liquid storage device 140 is greater than the second distance from the end of the base 111 facing the liquid storage device 140 to the liquid storage device 140, so as to prevent the seeping liquid matrix from sticking to the first tube 120, and to prevent the e-liquid from rising from the inner airway to the user's mouth when the user inhales, thereby improving the user's experience.

[0060] In one embodiment, the difference between the second distance and the first distance is greater than or equal to 0.5 mm, or in other words, the distance between the end of the first tube 120 facing the liquid storage component 140 and the end of the base 111 facing the liquid storage component 140 is greater than or equal to 0.5 mm.

[0061] This application provides an electronic atomizing device, see reference. Figure 5 , Figure 5 This is a cross-sectional schematic diagram of an electronic atomizing device 10 according to one or more embodiments of this application. The electronic atomizing device 10 includes an atomizer 100 and a power supply component 200. The power supply component 200 can provide electrical energy to the atomizer 100 to enable the atomizer 100 to atomize a liquid matrix into an aerosol. The atomizer 100 can be any of the atomizer 100 embodiments described above, and is not limited herein.

[0062] In one embodiment, the power supply assembly 200 includes a power supply adapter (not shown) and an electrode assembly (not shown). The atomizing core 130 includes a heating element (not shown). One end of the electrode assembly is electrically connected to the heating element, and the other end of the electrode assembly is electrically connected to the power supply adapter. The power supply adapter is configured to transfer electrical energy from outside the electronic atomizing device 10 to the electrode assembly to power the heating element. That is, the electronic atomizing device 10 in this embodiment is a battery-free electronic atomizing device 10. By setting the power supply adapter, the power supply assembly 200 realizes the on-demand charging function of the electronic atomizing device 10 using external power supply. In addition, the setting of the power supply adapter makes the electronic atomizing device 10 not require a battery, making the electronic atomizing device 10 more environmentally friendly.

[0063] In one embodiment, the power supply assembly 200 includes a battery cell 300 and an electrode assembly (not shown), and the atomizing core 130 includes a heating element (not shown). One end of the electrode assembly is electrically connected to the heating element, and the other end of the electrode assembly is electrically connected to the battery cell 300. That is, the electronic atomizing device 10 of this embodiment is an electronic atomizing device 10 with a battery cell 300, allowing users to use it at any time without needing an external power source.

[0064] It is worth noting that the power supply assembly 200 also includes circuitry for maintaining the normal operation of the electronic atomizing device 10, which can be found in a conventional electronic atomizing device 10 and will not be described in detail here.

[0065] In one embodiment, the battery cell 300 provides power for operating the electronic atomizing device 10. The battery cell 300 may be a rechargeable battery cell 300 or a disposable battery cell 300.

[0066] In one embodiment, the atomizer 100 is detachably or removably connected to the power supply assembly 200, including but not limited to snap-fit, magnetic, threaded connections, etc.

[0067] In one embodiment, the power supply assembly 200 includes circuitry (not shown) and a magnetic field generator (not shown), and the atomizing core 130 includes a sensor (not shown). The circuitry can control the overall operation of the electronic atomizing device 10. The circuitry controls not only the operation of the battery core 300 and the magnetic field generator, but also the operation of other components in the electronic atomizing device 10. The circuitry includes at least one processor. The processor may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing programs executable in the microprocessor. Furthermore, those skilled in the art will understand that the circuitry may include another type of hardware.

[0068] A magnetic field generator produces a changing magnetic field under alternating current. The magnetic field generator includes, but is not limited to, an induction coil. The magnetic field generator is electrically connected to the battery cell 300. The magnetic field generated by the generator can substantially cover the sensor; this reduces the coupling distance between the sensor and the generator, thereby improving the heating efficiency of the atomizer 100. In a preferred embodiment, the sensor and the magnetic field generator are coaxial, both extending along the axial direction of the electronic atomizing device 10, which is advantageous for improving the heating efficiency of the atomizer 100.

[0069] The receptor is configured to be inductively coupled to a magnetic field generator, and heats up when penetrated by a changing magnetic field, thereby heating the liquid matrix to generate an aerosol for inhalation.

[0070] In one embodiment, the liquid reservoir 140 absorbs the liquid matrix in the absorption chamber 113 through the through hole and delivers the absorbed liquid matrix to the sensor. The liquid reservoir 140 can surround the sensor to form an aerosol escape channel inside.

[0071] The reservoir 140 has the ability to retain liquid and can have any suitable capillary and porosity to be used in combination with different physical properties of liquid matrices, such as density, viscosity, surface tension and vapor pressure.

[0072] In one embodiment, the liquid storage element 140 may be made of ceramic or graphite materials or porous metals in the form of fibers or sintered powders, such as porous ceramics, porous glass, ceramic fibers, metal fibers, etc.

[0073] In one embodiment, the liquid reservoir 140 may be made of natural or man-made fiber materials, such as natural cotton fiber, glass fiber, sponge, non-woven fabric, etc. For example, the liquid reservoir 140 may be made of fibrous material made of spun or extruded fibers, such as cellulose acetate, polyester fiber, bonded polyolefin, polyethylene fiber, polypropylene fiber, nylon fiber, etc.

[0074] In one embodiment, the reservoir 140 includes a reservoir 140 made of high-density polyethylene (HDPE) or polyethylene terephthalate (PET).

[0075] In one embodiment, the reservoir 140 includes multiple layers of fiber pads. For example, the reservoir 140 is formed by stacking or winding at least two layers of fiber pads, each fiber pad comprising fiber bundles extending in a substantially one direction, with adjacent fiber pads having different directions of extension of the fiber bundles.

[0076] In one embodiment, the liquid storage component 140 is made of porous ceramic, the material of which includes at least one selected from alumina, zirconium oxide, kaolin, diatomaceous earth, and montmorillonite. The porosity of the porous ceramic can be adjusted within the range of 10% to 90%, and the average pore size can be adjusted within the range of 10 μm to 150 μm. In some embodiments, the adjustment can be made, for example, by selecting the amount and particle size of the pore-forming agent added.

[0077] In one embodiment, the liquid storage component 140 is a hollow cylinder or tube. The hollow cylindrical liquid storage component 140 has an inner wall that defines or forms the atomizing surface of the atomizing core 130, an outer wall that defines or forms the liquid absorption surface for absorbing the liquid matrix, and a hollow portion that defines a partial airflow channel. The atomized aerosol can flow together with the air to the nozzle of the electronic atomizing device 10.

[0078] The receptor may be made of at least one of the following materials: aluminum, iron, nickel, copper, bronze, cobalt, ordinary carbon steel, stainless steel, ferritic stainless steel, martensitic stainless steel, or austenitic stainless steel.

[0079] The receptor is a hollow cylinder or tube. Its outer diameter ranges from 0.5 mm to 20 mm; its wall thickness from 0.1 mm to 2 mm; and its height (axial length) from 1 mm to 50 mm. The receptor has multiple spaced-apart through-holes with a diameter of 0.1 mm to 0.5 mm. The through-holes can be circular, elliptical, triangular, rhomboid, or other regular or irregular shapes.

[0080] The sensor can be placed on the inner surface of the liquid storage component 140 or embedded in the liquid storage component 140.

[0081] In one embodiment, the receptor is configured as a closed loop or a non-closed loop tubular shape, and the receptor is a sheet-like metal mesh wound and supported on the inner surface of the reservoir 140.

[0082] In one embodiment, the sensor is embedded within the liquid reservoir 140 and is integrally formed with the liquid reservoir 140 by co-firing. In this way, the liquid matrix does not need to be conducted to the surface of the sensor before atomization, but begins to be heated and atomized near the sensor. On the one hand, this prevents dry burning when there is thermal contact between the sensor and the liquid reservoir 140, and on the other hand, most of the liquid matrix does not come into direct contact with the sensor during atomization, thus avoiding metal contamination from the sensor.

[0083] In one embodiment, the sensor may include multiple spaced closed loops, each loop comprising the same or different metallic materials, for example, the Curie temperature points of the materials of different closed loops are different.

[0084] In one embodiment, the electronic atomizing device 10 further includes a liquid supply device 400 and a pump device 500. When the pump device 500 is running, the liquid supply device 400 injects a liquid matrix into the chamber 113 through the injection port 119, and the atomizer 100 discharges gas into the liquid supply device 400 through the exhaust port 118. More specifically, when the pump device 500 is running, it first draws gas from the chamber 113 through the exhaust port 118, causing the gas pressure in the chamber 113 to drop below the gas pressure of the liquid supply device 400. Based on the pressure difference, the liquid supply device 400 automatically injects a liquid matrix into the chamber 113. Furthermore, as the pump device 500 operates, it injects the gas it draws from the chamber 113 into the liquid supply device 400 to prevent the liquid supply device 400 from being blocked from supplying liquid to the chamber 113 due to the decrease in gas pressure caused by the reduction in the liquid matrix.
