As shown in fig. 1-10, the atomizing device 10 includes a mouthpiece 11, a housing 12, a base 13, a first seal 14, a second seal 15, a third seal 16, an atomizing core 17, a support 18, a fourth seal 19, a fifth seal 20, a sixth seal 21, a seventh seal 22, a base 23, an insulator 24, and a conductor 25. The sealing members can be made of soft materials, such as silica gel.

The mouthpiece 11 is held at the upper end of the housing 12, and a portion of the mouthpiece 11 is located between the base 13 and the housing 12. The mouthpiece 11 is a hollow structure with two open ends. The interior hollow defines part of an aerosol passage through which a user may inhale aerosol from an opening in the upper end of the mouthpiece 11. The inside of the mouthpiece 11 is provided with a connection portion by which it is connected to the base 13. In a preferred embodiment, the connection is a threaded connection to achieve a threaded connection with the threaded connection of the base 13.

The first seal 14 is configured to provide a seal between an end face of the upper end of the housing 12 and the mouthpiece 11. Specifically, the first seal 14 comprises a tubular body, a flange extending radially outwardly from the tubular body, the body being sleeved over the mouthpiece 11; the tubular body is able to constrain the radially extending flange so as to avoid horizontal deflection during longitudinal assembly of the mouthpiece 11, ensuring that the flange provides good tightness. After assembly, the body of the first seal 14 is clamped at least partially between the outer surface of the mouthpiece 11 and the inner surface of the housing 12, and the flange of the first seal 14 is clamped between the mouthpiece 11 and the end face of the upper end of the housing 12, thereby effecting a seal against liquid matrix flowing out of the gap between the mouthpiece 11 and the end face of the upper end of the housing 12.

The second seal 15 and the third seal 16 are both annular and circular in cross-section. The second seal 15 and the third seal 16 are sleeved on the base 13 at intervals along the axial direction of the atomizing device 10. After assembly, the second seal 15 and the third seal 16 remain between the mouth 11 and the outer surface of the base 13, thereby achieving a seal.

The housing 12 has a tubular structure with two open ends. A liquid storage cavity A is arranged in the shell 12. Specifically, the reservoir A is defined at least in part by a gap between the inner surface of the housing 12 and the outer surface of the base 13. The liquid storage cavity A is used for storing liquid matrix. The liquid matrix may be injected into the reservoir A through an opening in the upper end of the housing 12. The housing 12 may be made of a transparent material so that the liquid matrix stored in the liquid reservoir A may be observed by a user. The housing 12 may also be made of a non-transparent material.

The base 13 is of generally tubular configuration. An opening is formed between the outer surface of the base 13 and the inner surface of the housing 12, within which opening a portion of the mouthpiece 11 is removably received. The base 13 may be integrally drawn from a metal base material. The base 13 includes a connection section 131, a transmission section 132, and a receiving section 133, which are sequentially connected.

One end of the connecting section 131 is connected with the transmitting section 132, and the other end extends out of the housing 12 to be connected with the mouthpiece 11. In a preferred embodiment, the connecting section 131 has a threaded connection. Grooves are also provided in the connecting section 131 at intervals to accommodate at least part of the second and third seals 15, 16.

The transfer section 132 is disposed within the housing 12. The conveying section 132 is mainly used for conveying the aerosol heated and atomized by the atomizing core 17 in the accommodating section 133 to the connecting section 131.

The lower end of the accommodating section 133 extends out of the housing 12 and is accommodated in the base 23. The inside and outside diameters of the receiving section 133 are larger than the inside and outside diameters of the transmitting section 132. The atomizing core 17, the support 18, the fourth seal 19, and the fifth seal 20 are all housed in the housing section 133. The receiving section 133 has through holes 133a and 133b, and the shape and number of the through holes 133a and 133b are not limited. The liquid matrix stored in the liquid storage chamber a can be transferred to the atomizing core 17 through the through holes 133a and 133 b.

The base 13 further includes an extension 134 extending radially from the receiving section 133 toward the inner surface of the housing 12, the extension 134 being abuttable against the inner surface of the housing 12. The sixth sealing member 21 is annular and has a circular cross section, the sixth sealing member 21 is sleeved on the accommodating section 133 and is located below the extension 134, and after assembly, the sixth sealing member 21 is maintained between the outer surface of the accommodating section 133 and the inner surface of the housing 12, so that sealing is achieved. The seventh seal 22 is annular and square in cross section, and the seventh seal 22 is configured to seal between an end face of the lower end of the housing 12 and an end face of the upper end of the base 23.

The atomizing core 17 includes a porous body 171 and a heating element 172.

The porous body 171 may be made of metal, ceramic, glass, or the like. In a preferred embodiment, the porous body 171 is a porous ceramic, and the porous ceramic is made of at least one of alumina, zirconia, kaolin, diatomaceous earth, and montmorillonite. The porosity of the porous ceramic can be adjusted within the range of 10% -90%, and the average pore diameter can be adjusted within the range of 10-150 mu m. In some implementations, the adjustment can be made, for example, by the amount of pore former addition and pore former particle size selection.

The porous body 171 includes a first partial porous body 171a, and a second partial porous body 171b protruding from the first partial porous body 171 a.

The first partial porous body 171a has a cylindrical shape with an outer diameter slightly smaller than the inner diameter of the receiving section 133, so that when the porous body 171 is received in the receiving section 133, the peripheral side surface of the first partial porous body 171a is in close proximity to the inner surface of the receiving section 133. The first partially porous body 171a has an upper surface facing the reservoir a and a lower surface facing away from the reservoir a. The heating element 172 is provided on the lower surface of the first partially porous body 171a, and thus the lower surface may also be referred to as an atomizing surface.

The cross-sectional area of the second partially porous body 171b is smaller than the cross-sectional area of the first partially porous body 171 a. The second partially porous body 171b extends from a part of the upper surface of the first partially porous body 171a toward the reservoir a or to an end surface of the upper end of the second partially porous body 171 b. The other part of the upper surface of the first part of porous body 171a and/or the peripheral side surface of the second part of porous body 171b define a liquid suction surface, and the liquid medium transferred to the atomizing core 17 through the through holes 133a and 133b can be transferred toward the atomizing surface after being sucked by the liquid suction surface.

The porous body 171 further includes a first air flow hole 171c and a second air flow hole 171d, and the first air flow hole 171c and the second air flow hole 171d each penetrate through the first partially porous body 171a and the second partially porous body 171b. The air inlet ends of the first air flow holes 171c and the second air flow holes 171d are provided on the atomizing face, and the air outlet ends of the first air flow holes 171c and the second air flow holes 171d are provided on the end face of the upper end of the second partially porous body 171b. The heating element 172 heats the atomized aerosol, which may flow into the transport section 132 through the first air flow holes 171c and/or the second air flow holes 171 d.

In an example, the air inlet ends and the air outlet ends of the first air flow holes 171c and the second air flow holes 171d are spaced apart, i.e., the first air flow holes 171c and the second air flow holes 171d form air flow channels independent of each other. The shortest distance between the inlet ends of the two is between 1mm and 2mm, and in a specific example, the distance between the inlet ends of the two is about 1.5mm. The cross sections of the first air flow holes 171c and the second air flow holes 171d are circular, and the inner diameter of the first air flow holes 171c or the second air flow holes 171d is 1mm to 3mm, and in a specific example, the inner diameter is 2mm. The distance d between the center of the first air flow hole 171c and the center of the second air flow hole 171d is 3mm to 4mm, and in a specific example, the distance d is 3.5mm.

In one example, as shown in fig. 5-6, the air inlet ends of the first air flow holes 171c and the second air flow holes 171d are spaced apart, and the air outlet ends are in communication to form an air flow merging chamber in the second partially porous body 171b, the air flow merging chamber being defined at an end face of the second partially porous body 171b, the air flow merging chamber being in fluid communication with the transfer section 132.

It is understood that the number of the airflow through holes may be three or more. By providing a plurality of airflow through holes in the porous body 171, the risk of clogging of the airflow through holes due to condensate can be reduced, enhancing the user's suction experience. In a further implementation, a ventilation tube may be disposed in the first air flow hole 171c or the second air flow hole 171d, where the ventilation tube is made of a material that is not permeable to the liquid matrix, for example: metal, plastic, dense ceramic, glass, and the like. In this way, the risk of clogging can be further avoided.

The materials of the first partial porous body 171a and the second partial porous body 171b may be the same or different. In one example, the first portion of the porous body 171a may be made of a material with better liquid matrix transfer efficiency, so as to facilitate the transfer of the liquid matrix to the atomizing surface; the second partially porous body 171b may be made of a general material, so as to prevent excessive liquid matrix from penetrating toward the first air flow holes 171c or the second air flow holes 171d without being atomized by heating.

The heating element 172 avoids the air inlet ends of the first and second air flow holes 171c and 171d for heating the liquid matrix to generate aerosol. The heating element 172 includes a heating circuit 172a, a first electrode 172b, and a second electrode 172c.

The first electrode 172b and the second electrode 172c are formed in a circular shape, or may be formed in a square shape, an oval shape, or the like in other examples, and gold, silver, or the like having a low resistivity and high conductivity is preferably used as the first electrode 172b and the second electrode 172 c.

The first electrode 172b and the second electrode 172c are symmetrically disposed on both sides of the air inlet ends of the first air flow hole 171c and the second air flow hole 171 d. In a preferred embodiment, as shown in fig. 7, a line B1B2 between the center of the first electrode 172B and the center of the second electrode 172c is substantially perpendicular to a line A1A2 between the center of the first air flow hole 171c and the center of the second air flow hole 171 d; in this way, the arrangement of the heating line 172a is facilitated.

The heating circuit 172a is formed in a serpentine manner on the atomizing face, which may be printed, deposited, sintered, or physically assembled. The heating circuit 172a is typically made of a resistive metal material, a metal alloy material with suitable resistance, based on the functional requirements for heating atomization; for example, suitable metals or alloy materials include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nichrome, nickel-iron alloys, iron-chromium alloys, titanium alloys, iron-manganese-aluminum based alloys, or stainless steel, among others.

As will be understood from fig. 8, the heating line 172a includes an extension 172a1 extending from the first electrode 172b toward the air inlet end of the first air flow hole 171c, a curved section 172a2 curved from the extension 172a1 with a predetermined curvature portion around the air inlet end of the first air flow hole 171c, an extension 172a3 extending from the curved section 172a2 toward the air inlet end of the second air flow hole 171d, a curved section 172a4 curved from the extension 172a3 with a predetermined curvature portion around the air inlet end of the second air flow hole 171d, and an extension 172a5 extending from the curved section 172a4 toward the second electrode 172 c. Wherein the air inlet end of the first air flow hole 171c is located between the extending section 172a1 and the extending section 172a3, the air inlet end of the second air flow hole 171d is located between the extending section 172a3 and the extending section 172a5, and the air inlet ends of the first air flow hole 171c and the second air flow hole 171d are located at both sides of the extending section 172a 3; the curvature or radius of curvature of the curved segment 172a2 may be the same or different than the curvature or radius of curvature of the curved segment 172a 4. The curved sections 172a2 and 172a4 are reversely curved. The above arrangement of the heating line 172a can enhance the atomization efficiency of the liquid matrix.

The fourth sealing member 19 is provided between the end face of the upper end of the second partially porous body 171b and the inner surface of the receiving section 133, thereby achieving sealing. In further implementation, an air pressure balancing channel may be provided between the end surface of the upper end of the second partially porous body 171b and the fourth sealing member 19 to balance the air pressure inside and outside the liquid storage chamber a so that the liquid medium can be smoothly transferred toward the porous body 171. In this example, the air pressure balancing passage is realized by a groove 171e opened at the end face of the upper end of the second partial porous body 171b, so that the air in the first air flow hole 171c or the second air flow hole 171d can flow to the liquid storage chamber a through the groove 171 e. The groove 171e spans an end face of the upper end of the second partially porous body 171b, and may extend along a peripheral side face of the second partially porous body 171 b.

The support 18 is generally tubular. The support 18 is disposed below the atomizing core 17, and the lower end of the support 18 may be flush with the lower end of the receiving section 133. A part of the fifth seal 20 is provided between the outer surface of the support member 18 and the inner surface of the receiving section 133, and another part of the fifth seal 20 is provided between the atomizing face and the end face of the upper end of the support member 18, thereby achieving sealing. The hollow portion of the interior of the support 18 defines an atomising chamber.

The support 18 further has a support portion 181, a support portion 182, and a receiving groove 183. The supporting portion 181 is used for supporting the first electrode connector D1, and the supporting portion 182 is used for supporting the second electrode connector D2. One end of the first electrode connecting member D1 contacts the first electrode 172b to form an electrical connection, and the other end contacts the conductive member 25 to form an electrical connection; one end of the second electrode connector D2 contacts the second electrode 172c to form an electrical connection, and the other end contacts the base 23 and/or the receiving section 133 to form an electrical connection. The base 23 is insulated from the conductive member 25 by an insulating member 24. The receiving groove 183 can be used to receive the condensed liquid matrix, and prevent the liquid matrix from flowing to the power supply assembly.

The base 23 includes an integrally formed receiving portion and a connecting portion (not shown). The partial accommodating section 133 is accommodated in the accommodating portion, and an end surface of the lower end of the base 13 can abut against the bottom wall of the accommodating portion. The connection part is used for being detachably connected with the power supply assembly, and preferably adopts threaded connection. An insulating member 24 and a conductive member 25 are provided in the connection portion.

The lower end of the conductive member 25 has an opening, the upper end is closed, and the peripheral side surface has one or more air flow outlets; thus, the liquid matrix or the condensed liquid matrix cannot flow in through the upper end of the conductive member 25 and flow out from the lower end opening thereof to the power supply assembly; the external air flows in from the lower end opening of the conductive member 25 and flows out from the air flow outlet of the peripheral side surface thereof, sequentially passes through the atomizing chamber, the first air flow hole 171c or the second air flow hole 171d, the transfer section 132, and the connection section 131, then flows in to the mouthpiece 11, and finally flows out from the opening of the upper end of the mouthpiece 11.

It should be noted that while the present application has been illustrated in the drawings and described in connection with the preferred embodiments thereof, it is to be understood that the application may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but are to be construed as providing a full breadth of the disclosure. The above-described features are further combined with each other to form various embodiments not listed above, and are considered to be the scope of the present application described in the specification; further, modifications and variations of the present application may be apparent to those skilled in the art in light of the foregoing teachings, and all such modifications and variations are intended to be included within the scope of this application as defined in the appended claims.
