In other examples, the atomizing device may also be an integrally formed device including a power supply assembly, an atomizer, and the like.
As shown in fig. 1-2, an atomizing device 10 according to an embodiment of the present application includes a mouthpiece 11, a connector 12, an extension 13, a seal 14, a seal 15, a housing 16, a base 17, an atomizing core 18, a vent pipe 19, a seal 20, a seal 21, a seal 22, a seal 23, a base 24, an insulator 25, and a conductive member 26. 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 16. 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 connecting member 12, and is connected to a base 17 via the connecting member 12. In a preferred embodiment, the connector 12 is snap-fitted to the base 17. One end of the extension 13 protrudes into the mouthpiece 11 and is held between the inner wall of the mouthpiece 11 and the connector 12, and the other end of the extension 13 protrudes into the housing 16 and is held between the base 17 and the housing 16.
The seal 14 is configured to provide a seal between the end face of the upper end of the housing 16 and the mouthpiece 11. Specifically, the seal 14 comprises a tubular body, a flange extending radially outward from the tubular body, the body being sleeved on the extension 13; 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 seal 14 is clamped at least partially between the outer surface of the extension 13 and the inner surface of the housing 16, and the flange of the seal 14 is clamped between the mouth piece 11 and the end face of the upper end of the housing 16, thereby effecting a seal.
The seal 15 is annular and circular in cross-section. The extension 13 has a recess in which the seal 15 is at least partially received. After assembly, the seal 15 is held between the extension 13 and the outer surface of the base 17, thereby effecting a seal.
The housing 16 is a tubular structure open at both ends. A liquid storage cavity a is provided in the housing 16. Specifically, the reservoir A is defined at least in part by a gap between the inner surface of the housing 16 and the outer surface of the base 17. 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 16. The housing 16 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 16 may also be made of a non-transparent material.
As shown in fig. 3, the base 17 has a substantially tubular structure. An opening is formed between the outer surface of the base 17 and the inner surface of the housing 16. The susceptor 17 may be integrally drawn from a metal substrate. The base 17 includes a connection section 171, a transmission section 172, and a receiving section 173 connected in this order, and the inner and outer diameters of the connection section 171 are smaller than the inner and outer diameters of the transmission section 172, and the inner and outer diameters of the transmission section 172 are smaller than the inner and outer diameters of the receiving section 173.
One end of the connecting section 171 is connected with the transmitting section 172, and the other end extends out of the housing 16 to be connected with the mouthpiece 11 and the connecting member 12, specifically, a fastener can be sleeved on the connecting section 171 to be connected with the connecting member 12.
A delivery section 172 is positioned within the housing 16, the delivery section 172 being primarily configured to deliver heated atomized aerosol from the atomizing core 18 in the receiving section 173 to the connecting section 171. The extension 13 remains in contact or abutting contact with the outer surface of the transfer segment 172 but is spaced from the attachment segment 171.
The accommodating section 173 is used for accommodating the atomizing core 18, and a via hole 1731 is further formed on a side wall of the accommodating section 173, and the liquid matrix stored in the liquid storage cavity a can be transferred to the atomizing core 18 through the via hole 1731. Also between the through hole 1731 and the end of the lower end of the base 17 is an extension 1732 extending radially toward the inner surface of the housing 16, and the extension 1732 may abut against the inner surface of the housing 16.
The seal 22 is annular and circular in cross-section, the seal 22 is sleeved on the receiving section 173 below the extension 1732, and after assembly, the seal 22 is retained between the outer surface of the receiving section 173 and the inner surface of the housing 16, thereby achieving a seal. The seal member 23 is annular and square in cross section, and the seal member 23 is configured to seal between an end face of the lower end of the housing 16 and an end face of the upper end of the base 24.
As shown in fig. 4-5, the atomizing core 18 includes a porous body 181, a heating element 182, a first lead 183, and a second lead 184.
The porous body 181 may be made of metal, ceramic, glass, or the like. In a preferred embodiment, the porous body 181 is a porous ceramic, and the porous ceramic material includes 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 181 is substantially tubular. The porous body 181 includes a first portion 181a, and a second portion 181b protruding on the first portion 181a in the axial direction of the porous body 181 or the atomizing device 10.
The outer surface of the first portion 181a defines a liquid suction surface and is in fluid communication with the liquid reservoir A, and the liquid matrix delivered to the atomizing wick 18 through the via 1731, when sucked by the liquid suction surface, may be delivered toward the atomizing surface. The outer diameter of the first portion 181a is slightly smaller than the inner diameter of the housing section 173, so that when the porous body 181 is housed in the housing section 173, the peripheral side surface of the first portion 181a is in close proximity to the inner surface of the housing section 173.
The second portion 181b extends from the first portion 181a in a direction away from the reservoir a. The second portion 181b has a smaller cross-sectional area than the first portion 181a (the second portion 181b has an outer diameter smaller than the first portion 181 a), thereby forming a step between the first portion 181a and the second portion 181 b. The heating element 182 may be disposed on the outer surface of the second portion 181b, or partially embedded within the second portion 181b, or embedded within the second portion 181b and disposed adjacent to the outer surface of the second portion 181 b. The outer surface of the second portion 181b defines an atomizing face, and the gap between the outer surface of the second portion 181b and the inner surface of the receiving section 173 forms an atomizing chamber. Aerosol generated by heating by the heating element 182 may spill over into the aerosolization chamber through the aerosolization surface.
The hollow portion inside the tubular porous body 181 forms an airflow through hole B. The air inlet end of the air flow hole B is arranged on the end face of the second part 181B, and the air outlet end is arranged on the end face of the first part 181a, namely the air flow hole B penetrates through the first part 181a and the second part 181B. Because the atomizing chamber is in communication with and disposed adjacent the inlet end of the airflow aperture B, the heating element 182 heats the atomized aerosol to flow into the atomizing chamber, and then through the vent tube 19 or the airflow aperture B into the transfer section 172.
The breather tube 19 is made of a material that is impermeable to a liquid matrix, such as: metal, plastic, dense ceramic, glass, and the like.
In an example, the vent pipe 19 is a separate component, and the vent pipe 19 may be inserted in the airflow through hole B. The outer diameter of the vent pipe 19 may be slightly larger than the inner diameter of the airflow through hole B, so that the outer surface of the vent pipe 19 is in close contact with the surface of the airflow through hole B, i.e., the vent pipe 19 is held in the airflow through hole B; an adhesive material may also be provided between the outer surface of the breather pipe 19 and the surface of the air flow hole B so that the breather pipe 19 is held in the air flow hole B. The axial extension length of the vent pipe 19 is greater than that of the airflow through hole B, so that the upper end and/or the lower end of the vent pipe 19 can extend out of the airflow through hole B, and the heated and atomized aerosol is prevented from flowing to the surface of the airflow through hole B. Through the above-mentioned breather pipe 19, can reduce the air current through-hole B and because the jam risk that the condensate leads to, promote user's suction experience.
In an example, the breather pipe 19 may be a film layer formed on the inner surface of the air flow hole B, and the axial extension length of the film layer may be the same as the axial extension length of the air flow hole B.
The heating element 182 is configured as a spiral coil extending in the axial direction of the porous body 181 or the atomizing device 10, with an axial extension that is smaller than or equal to the axial extension of the second portion 181 b. One end of the first lead 183 is connected to the spiral coil, for example, welded, and the other end extends in a direction away from the porous body 181 to be coupled to the battery cell; the second lead 184 is similar thereto. The heating element 182 is typically a resistive metal material, 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. The first lead 183 and the second lead 184 are preferably made of gold, silver, or the like having a low resistivity and high conductivity.
The seal 20 is used to seal the gap between the first portion 181a and the inner surface of the receiving section 173, preventing the liquid matrix from flowing out of the gap between the first portion 181a and the inner surface of the receiving section 173. In this example, the seal 20 is sleeved on a portion of the ventilation pipe 19 extending out of the airflow through hole B, the peripheral side surface of the seal 20 is abutted against the inner surface of the accommodation section 173 by the convex ring, and the end surface of the bottom end of the seal 20 is abutted against the end surface of the first portion 181 a. By means of the seal 20, a gas-tight separation between the suction surface and the atomizing surface is achieved.
The seal 21 is sleeved on the second portion 181b, the peripheral side surface of the seal 21 is abutted against the inner surface of the accommodating section 173 through the convex ring, and the end surface of the top end of the seal 21 is abutted against the step in the porous body 181, thereby forming a seal. Via 1731 is interposed between seal 20 and seal 21.
The base 24 includes an integrally formed receiving portion and a connecting portion (not shown). The partial housing section 173 is housed in the housing portion, and the end surface of the lower end of the base 17 can abut against the bottom wall of the housing portion. The connection part is used for being detachably connected with the power supply assembly, and preferably adopts threaded connection. The base 24 is insulated from the conductive member 26 by an insulating member 25, and the insulating member 25 and the conductive member 26 are provided in the connection portion.
The conductive member 26 has an opening at a lower end thereof, a closed upper end thereof, and one or more air flow outlets at a peripheral side surface thereof; thus, the liquid matrix or condensed liquid matrix cannot flow in through the upper end of the conductive member 26 and out through the lower end opening thereof to the power supply assembly; the external air flows in from the lower end opening of the conductive member 26 and flows out from the air flow outlet on the peripheral side surface thereof, sequentially passes through the atomizing chamber, the air pipe 19, the transfer section 172 and the connection section 171, flows into the mouthpiece 11, and finally flows out from the opening on the upper end of the mouthpiece 11.
Fig. 6-7 illustrate an atomization device according to another embodiment of the present application. Unlike the examples of fig. 1-5, the following are: the second portion 181b extends from the first portion 181a in a direction toward the reservoir a, i.e., the atomizing core 18 in the examples of fig. 6-7 is inverted for use with respect to the atomizing core 18 in the examples of fig. 1-5. Because the atomizing chamber is in communication with and adjacent to the outlet end of the airflow aperture B, the heating element 182 heats the atomized aerosol to flow into the atomizing chamber and then into the transfer section 172 without passing through the vent tube 19 or the airflow aperture B, shortening the path between the atomizing chamber and the opening in 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.
