The following embodiments of the present application describe exemplary structures of the electronic atomizing device 1000.

Fig. 1 is a schematic perspective view of an embodiment of an electronic atomization device according to the present application. The electronic atomizing device 1000 provided herein includes an atomizer 100, and a power supply mechanism 200 for supplying power to the atomizer. The electronic atomizing device 1000 may be used for medical or other + applications. Wherein the atomizer 100 may be part of a split electronic atomizer 1000 for atomizing a liquid matrix stored therein. The power supply mechanism 200 is electrically connected to the atomizer 100, and may be internally loaded with a detachable battery for easy replacement by a user.

The following embodiments of the present application describe exemplary structures of the nebulizer 100.

As shown in fig. 2 and 3, fig. 2 is a schematic perspective view of an atomizer of the electronic atomizing apparatus shown in fig. 1; fig. 3 is a schematic cross-sectional structure of the atomizer shown in fig. 2. The atomizer 100 comprises a proximal end 1 and a distal end 2 facing away from each other in a longitudinal direction, an air suction opening 3, a liquid reservoir 4, a porous body 5, a heating element 6, a first receiving element 7. The atomizer 100 further comprises a second receiving member 8, an air inlet 9, a tubular member 10, a nozzle assembly 11, a housing 12, a base assembly 13, an air flow channel 14.

Wherein the suction opening 3 is located at the proximal end 1. An air inlet 9 is located at the distal end 2. The nozzle assembly 11 is adapted to define the proximal end 1 of the atomizer 100. The base assembly 13 is used to define the distal end 2 of the nebulizer 100. The interior of the suction nozzle assembly 11 is provided with a cavity, which is defined as the suction opening 3. The interior of the suction nozzle assembly 11 is likewise provided with a cavity, which is delimited by an air inlet 9. The housing 12 is connected to the end of the nozzle assembly 11 remote from the proximal end 1, and the base assembly 13 is closely connected to the other end of the housing 12 remote from the nozzle assembly 11.

The reservoir 4 is used for storing a liquid matrix. The liquid matrix may be a drug-containing liquid or other liquid matrix, typically of different physical and chemical shapes. For example, some liquid matrices have a higher viscosity, while others have a lower viscosity.

The tubular element 10 is disposed inside the housing 12, and has one end accommodated inside the suction nozzle assembly 11 and the other end accommodated inside the base assembly 13. The inner wall of the tubular element 10 serves to define an air flow channel 14. An air flow passage 14 is located between the air inlet 9 and the air suction opening 3.

The inner wall of the housing 12 and the outer wall of the tubular element 10 define the reservoir 4. A sealing ring 111 is provided inside the suction nozzle assembly 11. The sealing ring 111 is disposed around the outer periphery of the tubular element 10, and has one end accommodated at one end of the suction nozzle assembly 11 far away from the proximal end 1, and the other end extends into the housing 12 and abuts against the inner wall of the housing 12, so that the upper end 101 of the tubular element 10 is abutted against, and unnecessary displacement is prevented. The bottom end of the housing 12 is bent, and the edge extends to the lower end 102 of the tubular element 10, thereby supporting the outer periphery of the lower end 102 of the tubular element 10 to be fixed. Thus, the outer wall of the tubular element 10 and the inner wall of the housing 12 form a closed reservoir 4. The housing 12 may be made of transparent glass or resin, so as to facilitate the user to observe the content of the liquid matrix therein, and to be replenished after the liquid matrix is consumed.

As shown in fig. 2 and 3, the porous body 5 is in fluid communication with the reservoir 4 to receive or aspirate the liquid matrix and defines a through hole 51 through the porous body 5. The through hole 51 has a first end 511 facing the proximal end 1 and a second end 512 facing the distal end 2. The through-hole 51 further includes a first section 513 proximate the first end 511, and a second section 514 proximate the second end 512. Wherein the cross-sectional area of the second section 514 at least partially decreases in a direction approaching the first section 513. In this way, the condensate formed by the aerosol formed after the liquid matrix is atomized after the temperature is reduced is beneficial to flowing out along the direction of the outer Zhou Chaoyuan end 2 of the second section 514, so that the porous body 5 is prevented from being blocked by the condensate to influence the further atomization effect.

The air inlet 9, the air inlet 3 and the air flow channel 14 are arranged to define an air flow path from the air inlet 9 to the air inlet 3 via the through hole 51 to deliver aerosol to the air inlet 3.

The porous body 5 may be a structure made of ceramic, glass fiber, or other different materials having a certain porosity. For example, the porous ceramic material with the open pore diameter and the high open porosity is prepared by taking high-quality raw materials such as corundum sand, silicon carbide, cordierite and the like as main materials through molding and special high-temperature sintering processes, and has the advantages of high temperature resistance, high pressure resistance, acid resistance, alkali resistance, organic medium corrosion resistance, good biological inertia, controllable pore structure, high open porosity, long service life, good product regeneration performance and the like.

Fig. 4 is a schematic cross-sectional view of the porous body of the atomizer shown in fig. 3. Further, the porous body 5 may include a first portion 52 and a second portion 53. Wherein the first portion 52 surrounds or defines a first section 513 of the through-hole 51; the second portion 53 surrounds or defines a second section 514 of the through-hole 51.

As shown in fig. 3 and 4, in the present embodiment, a heating element 6 is coupled to the porous body 5 and disposed adjacent to the through-holes 51 for heating at least a portion of the liquid matrix within the porous body 5 to generate an aerosol. The heating element 6 may specifically include a heating wire 61, and a first lead wire 62 and a second lead wire 63 connected to both ends of the heating wire 61, respectively. The heating wire 61 is spirally wound on the inner wall of the porous body 5, which is favorable for sufficiently atomizing the liquid matrix absorbed by the porous body 5. In other embodiments, the heating wires 61 may be disposed in different forms such as a grid shape, so as to facilitate the full heating and atomization of the liquid substrates with different physicochemical properties. In the present embodiment, the heating wire 61 is embedded in the inner wall of the first portion 52 of the porous body 5 and avoids the second portion 53. In other embodiments, the heating wires 61 may be mesh-shaped and embedded in the first portion 52 and the second portion 53 of the porous body 5. The heating element 6 generates heat in an energized state to atomize the liquid matrix infiltrated from the outside of the porous body 5, and is typically made of a metal alloy such as nickel-chromium. The heating element 6 may be embedded in the porous body 5 by sintering or the like and integrally formed with the porous body 5. For example, the heating element 6 is fixed to a mold in advance by using ceramic powder or the like as a raw material of the porous body 5 to prepare a slurry, and the porous body 5 is implanted with the heating element 6 after press molding. The heating element 6 is arranged in the porous body 5, so that generated heat can be kept in the porous body, the heat energy can not be dissipated and can be fully utilized, the porous structure of the porous body 5 enables the liquid matrix to permeate into the porous body 5, and a good atomization effect is generated under the heating effect of the heating element 6.

With continued reference to fig. 5 and 6, fig. 5 is an enlarged schematic view of a portion of the atomizer shown in fig. 3; fig. 6 is a schematic perspective view of a first receiving member of the atomizer shown in fig. 3. A first receiving element 7 is located between the porous body 5 and the distal end 2 for receiving aerosol condensate from the through bore 51. The first receiving element 7 is provided with at least one flow guiding structure 71. The aerosol formed after the liquid matrix is atomized is liable to form condensate on the outer periphery of the porous body 5 after the temperature is lowered. The flow guiding structure 71 is arranged to extend from the first carrier element 7 towards the through hole 51 for guiding aerosol condensate within the through hole 51 towards the first carrier element 7. In the present embodiment, the first socket element 7 is provided in particular on the inner wall of the tubular element 10 near the lower end 102. In other embodiments, the first receiving element 7 may also be disposed inside the base assembly 13. In the present embodiment, the number of at least one flow guiding structure 71 is one. When the condensate has a low viscosity and high fluidity, it is possible to selectively provide only one flow guiding structure 71. In other embodiments, the number of one less flow directing structure 71 may be multiple, such as two, three, four, etc. The plurality of flow guiding structures 71 are arranged at intervals in the longitudinal direction of the first carrier element 7. When the condensate has a large viscosity and poor fluidity, a plurality of guide structures 71 may be optionally provided to improve the guiding efficiency.

The flow guiding structure 71 is configured to be a column extending from the first receiving member 7 toward the through hole 51. For example, the shape of the flow guiding structure 71 may be square column, cylinder, elliptic column, etc. In some embodiments, the cross-sectional area of the flow directing structure 71 may remain uniform. In other embodiments, the cross-sectional area of the flow guiding structure 71 may be configured to taper in the direction of the through hole 51 to facilitate guiding the condensate to flow rapidly. In this embodiment, the flow guiding structure 71 is in the shape of a square column with a uniform cross-sectional area.

The projected portion of the flow guiding structure 71 in the longitudinal direction of the atomizer 100 is located in the through hole 51. Since the condensate is partially suspended in the through-hole 51 while flowing along the inner wall of the porous body 5, arranging the flow guiding structure 71 such that the projected portion in the longitudinal direction of the atomizer 100 is located in the through-hole 51 facilitates receiving the condensate extending to the through-hole 51.

In the present embodiment, the flow guiding structure 71 is not in contact with the porous body 5 to form a gap. Along the longitudinal direction of the atomizer 100, a gap is maintained between the flow guide structure 71 and the second end 512 of the through hole 51 to define a capillary channel for adsorbing aerosol condensate by capillary action from the second end 512 of the through hole 51 onto the flow guide structure 71. The gap between the flow guiding structure 71 and the second end 512 of the through hole 51 is 0.2-2 mm. For example, the distance of the gap is 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 1.8mm, 2.0mm. In other embodiments, the flow guiding structure 71 may be arranged in direct contact with the porous body 5, i.e. no gap between the flow guiding structure 71 and the porous body 5. In this way, condensate may flow directly along the flow guiding structure 71. For example, when the viscosity of the liquid matrix is large, it may be selected to arrange the flow guiding structure 71 in direct contact with the porous body 5.

The surface of the first receiving member 7 adjacent the porous body 5 defines a recess 72 for receiving or retaining aerosol condensate. The condensate formed by the aerosol flows out along the direction towards the distal end 2, flows into the groove 72 under the guidance of the flow guiding structure 71, and prevents the porous body 5 from being blocked by the condensate to influence the further atomization effect.

The first receiving element 7 is provided with a first air hole 73 arranged substantially coaxially with the through hole 51; and the diameter of at least a portion of the first air holes 73 is smaller than the diameter of at least a portion of the through holes 51. The first air holes 73 provide for air to enter through the first air holes 73 into the through holes 51 in use. In this way, when the condensate in the groove 72 overflows too much, it can flow down the first air holes 73, preventing the first air holes 73 of the first receiving element 7 from being blocked. The cross-sectional area of the first air holes 73 becomes gradually larger in a direction away from the porous body 5. For example, the shape of the first air hole 73 may be a bell mouth shape, a cone shape, or the like. The horn mouth shape or the cone shape and the like are beneficial to accelerating the flow velocity of condensate.

The first receiving element 7 is further provided with two avoidance grooves, through which the first lead 62 and the second lead 63 extend into the base assembly 13, respectively.

With continued reference to fig. 3, 5 and 7, fig. 7 is a schematic perspective view of a second receiving member of the atomizer shown in fig. 3. A second receiving element 8 is located between the first receiving element 7 and the distal end 2 for receiving aerosol condensate flowing out of the first air aperture 73. The second receiving element 8 is spaced apart from the first receiving element 7 in the longitudinal direction of the atomizer 100. In the present embodiment, the second receiving element 8 is arranged in particular inside the base assembly 13. In other embodiments, the second socket element 8 may also be provided on the inner wall of the tubular element 10 near the lower end 102. In other words, the first receiving element 7 and the second receiving element 8 are both disposed on the inner wall of the tubular element 10 near the lower end 102, or the first receiving element 7 and the second receiving element 8 are both disposed inside the base assembly 13.

Optionally, the surface of the second receiving element 8 adjacent to the first receiving element 7 defines a cavity 81 for receiving or retaining aerosol condensate. The aerosol-forming condensate flows out in a direction towards the distal end 2, flows into the groove 72 under the guidance of the flow guiding structure 71, and continues to flow in the circumferential direction of the first air holes 73 when condensate in the groove 72 overflows. The cavity 81 is arranged in alignment with the distally facing side of the first receiving element 7, so that condensate flowing out of the first air holes 73 is received by the cavity 81, which serves as a double safeguard against clogging of the porous body 5 with condensate.

The second receiving element 8 is provided with a second air hole 82 arranged substantially coaxially with the first air hole 73; and the second air holes 82 have at least a portion of a smaller diameter than at least a portion of the first air holes 73. The second air holes 82 provide for air to enter through the second air holes 82 into the first air holes 73 and into the through holes 51 in use. In this way, when the condensate in the groove 72 overflows too much, it can flow down the first air holes 73 to the cavity 81, preventing the first air holes 73 of the first receiving element 7 from being blocked. The cross-sectional area of the second air hole 82 becomes gradually larger in a direction away from the first receiving member 7. For example, the shape of the second air hole 82 may be a bell mouth shape, a cone shape, or the like. The horn mouth shape or the cone shape and the like are beneficial to accelerating the flow of condensate.

The second receiving element 8 is also provided with two avoidance portions, the two avoidance portions are aligned with the two avoidance grooves formed in the first receiving element 7 one by one, and the first lead 62 and the second lead 63 extend into the base assembly 13 through the two avoidance grooves and the two avoidance portions respectively.

As shown in fig. 3 and 5, an insulating ring 131 is disposed on the inner wall of the base assembly 13, and an electrode 132 is sleeved on the inner wall of the insulating ring 131. Wherein the first and second leads 62 and 63 may be connected to the electrode 132 and the conductive base assembly 13, respectively, to generate heat upon energization to atomize the liquid matrix to form an aerosol. The electrode 132 and the base assembly 13 are used to electrically connect the positive and negative poles of the power mechanism, and the insulating ring 131 is used to insulate the electrode 132 from the base assembly 13 to prevent short circuits.

In summary, the present application provides the atomizer 100 with the first receiving member 7 to receive the aerosol condensate in the through hole 51. And the first receiving element 7 is provided with at least one flow guiding structure 71, which flow guiding structure 71 is arranged to extend from the first receiving element 7 towards the through hole 51, enabling to guide aerosol condensate in the through hole 51 towards the first receiving element 7, thereby avoiding that the through hole is blocked.

The foregoing description is only exemplary embodiments of the present application and is not intended to limit the scope of the present application, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present application, or direct or indirect application in other related technical fields are included in the scope of the present application.
