Description

Technical Field

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. People have attempted to replace these tobacco-burning articles by creating products that release compounds without combustion.

[0003] An example of such a product is a heating device that releases compounds by heating rather than burning materials. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol-providing products, such as so-called electronic atomization devices. These devices typically include a liquid matrix that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid matrix may include nicotine and / or fragrances and / or aerosol-generating substances (e.g., glycerol). Known electronic atomization devices replenish the liquid matrix to a reusable body through an independently replaceable liquid source. Utility Model Content

[0048] In one embodiment, the first body 100 can store more liquid matrix than the second body 200, so as to replenish the liquid matrix to the second body 200 during use. The second body 200 can store relatively less liquid matrix and atomize the liquid matrix to produce an aerosol. Before the first body 100 and the second body 200 are combined, they exist independently of each other; and after the first body 100 is combined with the second body 200, they jointly define a complete electronic atomization device for use or aerosol inhalation by the user. Or in some embodiments, the first body 100 is mainly used as a liquid source for storing more liquid matrix; the second body 200 defines the atomization function part for storing relatively less liquid matrix and atomizing to produce an aerosol.

[0049] In some embodiments, when the first body 100 and the second body 200 are separated or exist independently, they cannot be used or sucked by the user independently. Figures 1 to 4 As shown in the figure, the first body 100 at least partially defines a mouthpiece for a user to use or inhale; the second body 200 can atomize a liquid matrix to generate an aerosol. When the first body 100 is removed or separated from the second body 200, the first body 100 cannot atomize the liquid matrix to generate an aerosol alone, and the second body 200 cannot be inhaled by a user alone.

[0050] In some embodiments, the first body 100 and the second body 200 can only be used by the user when they are combined to define a complete electronic atomization device, and the liquid matrix inside them is completely recycled after being consumed. In some embodiments, after the first body 100 is combined with the second body 200 to define a complete electronic atomization device, the first body 100 cannot be disassembled or replaced from the second body 200.

[0051] Alternatively, in some other embodiments, the first body 100 is removably coupled to the second body 200; in use, the first body 100 is used as a consumable and can be replaced, while the second body 200 is reusable; when the liquid matrix in the first body 100 is consumed, the user can remove the consumed first body 100 from the second body 200 and replace it with a new first body 100.

[0105] See also Figures 7 to 12 As shown, the second body 200 further includes:

[0106] The flexible base 370 is arranged between the third support portion 3230 of the bracket 320 and the second end 220; the flexible base 370 is at least partially inserted into the third support portion 3230, thereby closing the opening of the third support portion 3230 and / or the second liquid storage chamber 324 toward the second end 220, and supporting the liquid holding element 330 and the atomization assembly. The flexible base 370 is made of, for example, flexible silicone, thermoplastic elastomer, etc.

[0107] Specifically, the base 370 is provided with a plug-in groove 372 for inserting and installing the tubular element 340; after assembly, the lower end of the tubular element 340 is inserted into the plug-in groove 372 of the base 370 for installation and fixation. After assembly, the liquid retaining element 330 and / or the tubular element 340 are longitudinally clamped or retained between the supporting inner wall 321 and the base 370.

[0108] according to Figures 7 to 12 As shown, the second body 200 further includes:

[0109] An air inlet 221, located at the second end 220, for allowing external air to enter during suction;

[0110] The air inlet passage 371 , defined by the base 370 , provides a flow path for delivering air entering through the air inlet 221 to the atomizing assembly.

[0111] according to Fig.11 and Fig.12 As shown, when the first body 100 is combined with the second body 200, the electronic atomization device defined includes:

[0112] The air flow channel provides a flow path from the air inlet 221 to the air outlet 113 via the atomizer assembly / heating element 360 to output the aerosol generated by the atomizer assembly / heating element 360 to the air outlet 113. In an embodiment, the complete air flow channel is partially defined by the second body 200 and partially defined by the first body 100.

[0113] Specifically, the complete airflow path during suction is as follows Fig.11 As shown by the middle arrow R2, the air entering from the air inlet 221 passes through the air inlet channel 371 to the atomizer assembly / heating element 360, and carries the aerosol generated by the heating element 360, passes through the annular insertion portion 313 of the sealing element 310 in turn, and then enters the aerosol output tube 111, and is finally output to the air outlet 113 to be inhaled by the user.

[0114] In some embodiments, the liquid retaining element 330 has an upper surface and a lower surface opposite to each other in the axial direction. The upper surface of the liquid retaining element 330 abuts against the port of the liquid input interface 322 connected to the second liquid storage chamber 324. In some other specific embodiments, the base 370 is provided with a plurality of protrusions extending toward the liquid retaining element 330; after assembly, the lower surface of the liquid retaining element 330 abuts against the protrusions and a gap is maintained between the base 370 and the liquid retaining element 330.

[0115] In some embodiments, the liquid retaining element 330 is prepared or formed from a single porous fibrous element.

[0116] Or in some other variations of the embodiment, the liquid retaining element 330 is formed by a plurality of porous fiber elements. For example, the liquid retaining element 330 includes a first porous fiber material layer and a second porous fiber material layer arranged in sequence along the axial direction. The upper surface of the liquid retaining element 330 is defined by the first porous fiber material layer; and the lower surface of the liquid retaining element 330 is defined by the second porous fiber material layer. The liquid retaining element 330 is formed by arranging the first porous fiber material layer and the second porous fiber material layer in layers on top of each other. In some embodiments, the second porous fiber material layer is made of a flexible capillary fiber material, such as natural cotton fiber, non-woven fiber, etc. In some embodiments, the first porous fiber material layer includes artificial cotton, or hard artificial cotton or artificial foam made of filamentous polyurethane. For example, the first porous fiber material layer uses 138# hard synthetic organic polymer fiber; for another example, the first porous fiber material layer uses 138# hard synthetic organic polymer fiber with a density of 0.1 to 0.9 mg / mm 3 The first porous fiber material layer is made of oriented fibers that are basically arranged along the length direction, width direction or radial direction. The oriented fibers are arranged in the length direction or width direction of the first porous fiber material layer, so that the first porous fiber material layer has a strong bending resistance and thus has a hard characteristic. Specifically, for example, the first porous fiber material layer is hard artificial cotton including oriented polyester fibers, or hard artificial cotton or artificial foam made of filamentous polyurethane.

[0117] according to Figures 7 to 12 As shown, after assembly, the upper surface of the liquid retaining element 330 abuts against the port of the liquid input interface 322 defined by the support element 320, and covers the port of the liquid input interface 322, so as to prevent or avoid the air in the liquid input interface 322 from communicating with the outside air through the gap or clearance between the liquid retaining element 330 and the third support portion 3230. When the liquid matrix in the second liquid storage chamber 324 is consumed, the portion of the liquid retaining element 330 close to the upper surface is free of liquid matrix, and the porous pores in this portion provide a capillary channel / channel for transmitting negative pressure between the liquid input interface 322 and the second liquid storage chamber 324, so that the liquid input interface 322 can maintain the same negative pressure or pressure as that in the second liquid storage chamber 324.

[0118] according to Fig.11 and Fig.12As shown, when the first body 100 is combined with the second body 200, the liquid output connector 144 passes through the avoidance hole 312 of the sealing element 310 and is inserted into the liquid input interface 322, thereby connecting the first liquid storage chamber 112 of the first body 100 and the second liquid storage chamber 324 of the second body 200. And, when the first body 100 is combined with the second body 200, the sealing element 310 at least partially provides a seal between the second body 200 and / or the bracket 320 and the liquid output connector 144. And according to Fig.11 and Fig.12 As shown, when the first body 100 is combined with the second body 200 , the liquid outlet 145 is inside the liquid input interface 322 and exposed to form conduction.

[0119] according to Fig.11 and Fig.12 As shown, when the first body 100 is combined with the second body 200, the liquid outlet 145 of the liquid output connector 144 is oriented toward the second liquid storage chamber 324 / liquid retaining element 330; and the liquid outlet 145 of the liquid output connector 144 is spaced apart from the liquid retaining element 330. Fig.11 and Fig.12 In the embodiment, the free end of the liquid output connector 144 inserted into the liquid input interface 322 is in non-contact with the liquid retaining element 330 located in the second liquid storage chamber 324 .

[0120] In an embodiment, a first spacing d11 is maintained between the liquid outlet 145 and the second liquid storage chamber 324 / liquid retaining element 330. In some embodiments, the first spacing d11 is approximately between 0.2 and 1.2 mm. In some further specific embodiments, the first spacing d11 is approximately 0.6 mm. In use, by maintaining the diameter and width of the liquid outlet 145 of the liquid output connector 144 at the capillary pore diameter, and / or having a first spacing d11 between the liquid outlet 145 and the second liquid storage chamber 324 / liquid retaining element 330, the liquid matrix flowing out of the liquid outlet 145 is prevented from being directly sucked away by the porous liquid retaining element 330.

[0121] according to Fig.11 and Fig.12As shown, the outer surface of the liquid output connector 144 is not in contact with the inner surface of the liquid input interface 322, and a second distance d12 is defined between the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322. In an embodiment, the second distance d12 is smaller than the first distance d11; thus, the capillary space between the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322 is defined by the second distance d12 to absorb the liquid matrix flowing out from the liquid outlet 145 to the first distance d11, so as to prevent the liquid matrix flowing out from the liquid outlet 145 from being directly sucked away by the porous liquid retaining element 330. In some embodiments, the second distance d12 is approximately between 0.1 and 0.8 mm; more specifically, the second distance d12 is approximately 0.3 mm.

[0122] In use, when the amount of liquid matrix absorbed and retained by the liquid retaining element 330 in the second liquid storage chamber 324 is sufficient, the negative pressure in the second liquid storage chamber 324 is lower than the preset threshold value, such as Fig.12 As shown by the middle arrow R11, the liquid matrix flowing out of the liquid outlet 145 is capillary-adsorbed on the surface of the liquid outlet 145 or the free end of the liquid output connector 144, thereby preventing the liquid matrix flowing out of the liquid outlet 145 from being directly delivered to the second liquid storage chamber 324; and further, as the liquid matrix in the liquid retaining element 330 is gradually consumed, the negative pressure in the second liquid storage chamber 324 increases, causing the pressure difference between the second liquid storage chamber 324 and the first liquid storage chamber 112 to reach a predetermined threshold value, the liquid matrix adsorbed in the liquid outlet 145 or the free end of the liquid output connector 144 flows to the liquid retaining element 330 under the pressure difference and is absorbed, as shown in FIG. Fig.12 As shown by the arrow R12 in the middle. When a predetermined amount of liquid matrix is ​​added to the second liquid storage chamber 324 so that the negative pressure of the second liquid storage chamber 324 is lower than the predetermined threshold again, the liquid matrix will no longer continue to flow out of the liquid outlet 145 and reach a balance to prevent the liquid matrix from being added to the second liquid storage chamber 324. In use, the liquid matrix can be added to the second liquid storage chamber 324 only according to the predetermined amount each time as the user's suction control; specifically, the electronic atomization device can respond to the user's suction, and automatically add the liquid matrix of the first body 100 to the second body 200 according to the predetermined amount during each suction process or during the lag period after the suction is completed.

[0123] according to Figures 3 to 12As shown, the number of the liquid output connectors 144 of the first body 100 may include multiple ones; for example, in the embodiment, the number of the liquid output connectors 144 of the first body 100 is two. And, the number of the liquid outlets 145 on each liquid output connector 144 may also include multiple ones. Then, in use, when the liquid matrix in the first liquid storage chamber 112 flows out from at least one of the liquid outlets 145 on the multiple liquid output connectors 144, at least another liquid outlet 145 is used as an air inlet for providing air to enter the liquid output connector 144 and then to the first liquid storage chamber 112, so as to maintain the pressure balance in the first liquid storage chamber 112.

[0124] according to Figures 3 to 12 As shown, the number of liquid output connectors 144 of the first body 100 is at least two, for example, the liquid output connector 144 may include a first connector and a second connector arranged in parallel; accordingly, the number of liquid input interfaces 322 on the second body 200 is also at least two, for example, the liquid input interface 322 may include a first interface and a second interface arranged in parallel. The first connector and the second connector are respectively arranged on both sides of the atomization assembly, and the first interface and the second interface are respectively arranged on both sides of the atomization assembly. In some embodiments, the free end of the first connector and the free end of the second connector are flush.

[0125] according to Figures 3 to 12 As shown, the first body 100 has two liquid output connectors 144, and each liquid output connector 144 is provided with a liquid outlet 145 at the free end; in use, when the liquid matrix in the first liquid storage chamber 112 is discharged from the liquid outlet 145 of one of the liquid output connectors 144, air enters the first liquid storage chamber 112 from the liquid outlet 145 of the other liquid output connector 144 to maintain the pressure balance in the first liquid storage chamber 112.

[0126] In an embodiment, the volume of the first liquid storage chamber 112 in the first body 100 is greater than the volume of the second liquid storage chamber 324 in the second body 200. The amount of liquid matrix that can be absorbed and stored by the first liquid storage chamber 112 is greater than the amount of liquid matrix that can be absorbed and stored by the second liquid storage chamber 324 in the second body 200. For example, in some specific embodiments, the first liquid storage chamber 112 in the first body 100 can absorb and store 5 to 20 mL of liquid matrix, more specifically, for example, 10 mL; the second liquid storage chamber 324 in the second body 200 can store 5 to 20 mL of 0.5 to 3 mL of liquid matrix, more specifically, for example, 2 mL.
