Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic atomization technology, and in particular to an electronic atomization device and a liquid storage device for the electronic atomization device. Background Art

[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 a material. 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 contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or a fragrance and / or an aerosol-generating substance (e.g., glycerol). Known electronic atomization devices replenish a liquid matrix to a reusable body by an independently replaceable liquid source. Utility Model Content

[0128] 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 generate 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, so that the user can use or inhale the aerosol.

[0129] 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 nozzle for the user to use or inhale; the second body 200 can atomize the 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 the user alone. 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 they are recycled as a whole after the liquid matrix inside them is consumed.

[0130] Or in some other embodiments, the second body 200 is used to atomize the liquid matrix to generate an aerosol; the first body 100 is removably coupled to the second body 200; the first body 100 is used as a consumable and can be replaced, and the second body 200 is reusable; when the liquid matrix in the first body 100 is consumed, the user can disassemble and replace the second body 200 with a new first body 100.

Therefore, in use, the liquid matrix in the first liquid storage chamber 112 in the first part 11 is visible through the exposed first part 11 of the first shell 10, which is beneficial for the user to observe the consumption or surplus of the liquid matrix in the first liquid storage chamber 112.

When the first body 100 is combined with the second body 200, the first guide structure 121 and the second guide structure 211 cooperate to provide guidance. Figures 1 to 7 As shown in FIG. 1 , the first guide structure 121 comprises ridges on the outer surface of the second portion 12 ; the ridges of the first guide structure 121 are substantially longitudinally extending.

A liquid output channel 143 is defined on the closing element 140 to provide a channel path for the liquid matrix in the first liquid storage chamber 112 to leave or be output. After assembly, the liquid matrix in the first liquid storage chamber 112 can only be output or leave from the liquid output channel 143 of the closing element 140. The closing element 140 is rigid, for example, made of a rigid polymer plastic.

[0145] In an embodiment, the cross-sectional area or diameter of the first section 1431 is greater than the cross-sectional area or diameter of the second section 1432. For example, in some specific embodiments, the diameter of the first section 1431 is 2.5-4.0 mm; the diameter of the second section 1432 is 1.5-3.0 mm.

[0146] according to Figures 1 to 7As shown, the closure element 140 is arranged in a substantially annular shape; the closure element 140 has a first flange 141 extending toward the proximal end 110; the first flange 141 surrounds and defines a first section 1431 of the liquid output channel 143. The first flange 141 also surrounds and defines a first tracheal insertion hole 142; in assembly, the aerosol output tube 111 passes through the first tracheal insertion hole 142 of the closure element 140. After the aerosol output tube 111 passes through the closure element 140, it is at least partially located between the closure element 140 and the distal end 120.

When the first body 100 is combined with the second body 200, the liquid output connector 144 is inserted or extended into the liquid input interface 322 of the second body 200, so that the liquid matrix in the first liquid storage chamber 112 is replenished to the second body 200. In some embodiments, the axial length of the liquid output connector 144 and / or the second section 1432 of the liquid output channel 143 is between 4 and 8 mm; for example, in a specific embodiment, the axial length of the second section 1432 of the liquid output channel 143 is 4.8 mm.

Furthermore, after assembly, in the longitudinal direction of the atomization module 300, a first spacing space 331 is defined between the liquid holding element 330 and the support element 320; and a second spacing space 332 is defined between the liquid holding element 330 and the base 370. And after assembly, the first spacing space 331 and the second spacing space 332 are connected through the gap between adjacent convex ridges 326. Alternatively, the second liquid storage chamber 328 has a first inner wall near the first end 210, which is defined by the support element 320; after assembly, the first spacing space 331 is formed between the upper surface of the liquid holding element 330 and the first inner wall. Alternatively, the second liquid storage chamber 328 has a second inner wall near the first end 210, which is defined by the base 370; after assembly, the second spacing space 332 is formed between the lower surface of the liquid holding element 330 and the second inner wall. Alternatively, the second liquid storage chamber 328 has an inner wall surrounding the second liquid storage chamber 328, and the inner wall is defined by the inner surface of the second liquid storage chamber 328; the ridges 326 are located on the inner wall of the second liquid storage chamber 328, and the gaps between the ridges 326 on the inner wall provide fluid connection between the first partition space 331 and the second partition space 332.

[0233] In some embodiments, the liquid retaining element 330 is defined by a single porous fiber element. Or in some other variations, 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 composed of the first porous fiber material layer and the second porous fiber material layer arranged in layers on top of each other.

[0234] In some embodiments, the second porous fiber material layer is made of a flexible capillary fiber material, such as natural cotton fiber, non-woven fabric fiber, and the like.

[0235] 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 0.1-0.9 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.

[0236] according to Figures 8 to 21 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 supporting element 320, so as to prevent or avoid the air in the liquid input interface 322 from communicating with the outside air through the first spacing space 331 and the ventilation channel 40. When the liquid matrix in the second liquid storage chamber 328 is consumed, the portion of the liquid retaining element 330 near the port of the liquid input interface 322 is free of liquid matrix, and the porous pores in this portion provide a channel for transmitting negative pressure between the capillary channel / liquid input interface 322 and the second liquid storage chamber 328, so that the capillary channel / liquid input interface 322 can maintain balance with the negative pressure or pressure in the second liquid storage chamber 328.

[0237] according to Fig.14 and Fig.15 As shown, when the first body 100 is combined with the second body 200, the liquid output connector 144 of the closing element 140 of the first body 100 at least partially extends into or penetrates the liquid input interface 322, thereby connecting the first liquid storage chamber 112 of the first body 100 and the second liquid storage chamber 328 of the second body 200.

[0238] according to Fig.14 and Fig.15As shown, when the first body 100 is combined with the second body 200, the liquid outlet 145 on the liquid output connector 144 of the closing element 140 is located in the liquid input interface 322. Also, 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 first distance d11 is defined between the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322. Also, the free end of the liquid output connector 144 inserted into the liquid input interface 322 is not in contact with the liquid retaining element 330 located in the second liquid storage chamber 328, and a second distance d12 is defined between the liquid output connector 144 and the liquid retaining element 330.

[0239] In an embodiment, the first spacing d11 and / or the second spacing d12 is approximately between 0.1 and 1.5 mm; for example, in a specific embodiment, the first spacing d11 and / or the second spacing d12 is 0.25 mm. In use, the capillary channel between the liquid output connector 144 and the liquid input interface 322 is defined by the first spacing d11; and the capillary channel defined by the first spacing d11 adsorbs and retains the liquid matrix flowing out of the liquid outlet 145 on the liquid output connector 144, so as to prevent the liquid matrix in the first liquid storage chamber 112 from being replenished in large quantities to the second liquid storage chamber 328.

[0240] In use, the capillary channel defined by the first distance d11 can control the liquid matrix in the first liquid storage chamber 112 to be replenished to the second liquid storage chamber 328 according to a predetermined amount through capillary action, which is beneficial for preventing the second liquid storage chamber 328 from being oversaturated with liquid matrix.

[0241] Specifically, in use, when the amount of liquid matrix absorbed and retained by the liquid retaining element 330 in the second liquid storage chamber 328 is relatively sufficient, the negative pressure or pressure in the second liquid storage chamber 328 and / or the first interval space 331 is lower than the preset threshold value, and at this time, the liquid matrix flowing out of the liquid outlet 145 on the liquid output connector 144 is adsorbed and retained in the capillary channel defined by the first spacing d11 and forms a liquid film to close the liquid outlet 145, thereby preventing the liquid matrix in the first liquid storage chamber 112 from being replenished in large quantities to the second liquid storage chamber 328. When the liquid matrix absorbed and retained by the liquid retaining element 330 in the second liquid storage chamber 328 and / or the first interval space 331 is consumed so that the negative pressure in the second liquid storage chamber 328 and / or the first interval space 331 exceeds the preset threshold value, the liquid matrix retained in the capillary channel defined by the first spacing d11 under the drive of the negative pressure flows into and is replenished in the second liquid storage chamber 328 along the inner surface of the liquid input interface 322, as shown in FIG. Fig.14 and Fig.15As shown by the arrow R12 in the middle. When a predetermined amount of liquid matrix is ​​added to the second liquid storage chamber 328 so that the negative pressure of the second liquid storage chamber 328 and / or the first compartment 331 is lower than the predetermined threshold again, the liquid matrix flowing out of the liquid outlet 145 on the liquid output connector 144 is adsorbed in the capillary channel defined by the first spacing d11 to reach equilibrium and prevent the liquid matrix from being further added to the second liquid storage chamber 328. Furthermore, by maintaining the capillary channel defined by the first spacing d11 between the liquid output connector 144 and the liquid input interface 322, the first liquid storage chamber 112 can be controlled to only add the liquid matrix to the second liquid storage chamber 328 according to the predetermined amount each time as the user draws or uses.

[0242] Or in some other variant embodiments, the capillary channel defined by the first distance d11 can also be variably replaced by a capillary groove on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322. In this variant embodiment, when the liquid output connector 144 is inserted into the liquid input interface 322, the outer surface of the liquid output connector 144 can be against or in contact with the inner surface of the liquid input interface 322, and the capillary channel is defined between them by the capillary groove on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322.

[0243] Or in some other embodiments, a plurality of ridges extending in the longitudinal direction are arranged on the outer surface of the liquid output connector 144, and the plurality of ridges are arranged at intervals around the liquid output connector 144 in the circumferential direction. When the liquid output connector 144 is inserted into the liquid input interface 322, a capillary channel between the liquid output connector 144 and the liquid input interface 322 is defined by the gaps between the plurality of ridges.

[0244] exist Fig.14 and Fig.15 As shown, the second distance d12 defined between the liquid output connector 144 and the liquid retaining element 330 can prevent the liquid matrix in the capillary channel defined by the first distance d11 from being absorbed by the porous liquid retaining element 330 .

[0245] In an embodiment, the diameter of the second section 1432 of the liquid output channel 143 defined in the liquid output connector 144 is greater than the diameter of the liquid outlet 145 on the side wall of the liquid output connector 144; and the diameter of the liquid outlet 145 is greater than the first distance d11. Through such an arrangement, the area of ​​the channel during the outflow of the liquid matrix is ​​gradually reduced, which is beneficial for gradually reducing the flow rate and improving the lock liquid to achieve a predetermined amount of liquid matrix supply.

[0246] according to Figures 3 to 15As 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.

[0247] according to Figures 3 to 15 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. And, the distance between the liquid outlet 145 on the first connector and the free end is equal to the distance between the liquid outlet 145 on the second connector and the free end.

[0248] For example, in the embodiment, two liquid outlets 145 opposite to each other in the radial direction are arranged on the side wall of each liquid output connector 144; when the liquid matrix in the liquid output connector 144 flows out from one of the two liquid outlets 145, the air in the second liquid storage chamber 328 and / or the first partition space 331 enters the liquid output connector 144 from the other of the two liquid outlets 145.

[0249] according to Figures 10 to 21As shown by the middle arrow R3, the atomization module 300 further defines a ventilation channel 40 for connecting the second liquid storage chamber 328 and / or the first compartment 331 with the air flow channel passing through the atomization module 300. The ventilation channel 40 is used to balance the pressure in the second liquid storage chamber 328 and / or the first compartment 331; for example, when the negative pressure in the second liquid storage chamber 328 and / or the first compartment 331 exceeds a predetermined threshold, the ventilation channel 40 provides a channel path for air to enter the second liquid storage chamber 328 and / or the first compartment 331 to relieve the pressure in the second liquid storage chamber 328 and / or the first compartment 331; for another example, when the liquid holding element 330 of the second liquid storage chamber 328 adsorbs the liquid matrix supersaturatedly, causing the internal pressure to exceed the predetermined threshold, the air in the second liquid storage chamber 328 and / or the first compartment 331 is discharged to the outside through the ventilation channel 40 to relieve the pressure in the second liquid storage chamber 328 and / or the first compartment 331.

[0250] according to Figures 10 to 21 As indicated by the middle arrow R3 , the ventilation channel 40 is formed or defined between the supporting element 320 and the second sealing element 310 .

[0251] The ventilation channel 40 includes a first ventilation groove 316 arranged on the outer surface of the extension wall 315. Specifically, the second sealing element 310 is provided with an extension wall 315 that at least partially extends from the connection hole 321 of the support element 320 into the tubular element 340; and when the extension wall 315 partially extends into the tubular element 340, the extension wall 315 and the liquid guide element 350 are arranged at intervals, for example, there is a spacing of 0.2 to 2.0 mm between them. And, the extension wall 315 is annular in shape, partially extends from the connection hole 321 of the support element 320 into the tubular element 340, at least partially surrounds or defines the airflow channel passing through the atomization module 300. After assembly, a gap is maintained between the extension wall 315 and the tubular element 340 through the ventilation groove 316, so that the ventilation channel 40 is connected with the airflow channel through the ventilation groove 316.

[0252] The ventilation channel 40 further includes a second ventilation groove 324 arranged on the surface of the supporting element 320, and a ventilation hole 325 extending from the second ventilation groove 324 to the second liquid storage chamber 328 and / or the first spacing space 331. After assembly, the second ventilation groove 324 is at least partially opposite to, aligned with, or overlapped with the first ventilation groove 316, and then after assembly, the second ventilation groove 324 is connected to the first ventilation groove 316; thus, the ventilation hole 325, the second ventilation groove 324, and the first ventilation groove 316 jointly define the ventilation channel 40 that connects the second liquid storage chamber 328 and / or the first spacing space 331 with the airflow channel.

[0253] In the embodiment, the second ventilation groove 324 is arranged on the bottom wall of the first accommodating cavity 327. And, the ventilation hole 325 and the first ventilation groove 316 are respectively connected to the two sides of the second ventilation groove 324. Alternatively, the second ventilation groove 324 extends from the ventilation hole 325 to the first ventilation groove 316. Alternatively, in some other variant embodiments, the second ventilation groove 324 can also be arranged on the surface of the second sealing element 310 facing the supporting element 320.

[0254] In the embodiment, the diameter or width of the ventilation channel 40 is between 0.2 and 2.0 mm; for example, the diameter or width of the ventilation hole 325 / the second ventilation groove 324 / the first ventilation groove 316 is between 0.2 and 2.0 mm.

[0255] In use, when the user does not draw suction, the first distance d11 between the liquid output connector 144 of the first body 100 and the liquid input interface 322 of the second body 200 absorbs the liquid matrix flowing out of the liquid outlet 145, and is in a balanced state with the pressure of the second liquid storage chamber 328; when the user draws suction, as the liquid matrix is ​​consumed and the negative pressure in the air flow channel increases, the negative pressure of the second liquid storage chamber 328 increases to exceed a predetermined threshold, thereby destroying the balance, and the negative pressure of the second liquid storage chamber 328 can be transmitted to the liquid input interface 322 through the material gap of the liquid retaining element 330. The liquid matrix adsorbed in the first interval d11 then seeps downward into the second liquid storage chamber 328 and is absorbed by the liquid retaining element 330; until the user stops inhaling, air enters the second liquid storage chamber 328 from the ventilation channel 40, and the amount of liquid matrix added to the second liquid storage chamber 328 jointly relieves the negative pressure in the second liquid storage chamber 328 to a predetermined range, the liquid matrix adsorbed in the first interval d11 forms a liquid film to close the liquid outlet 145, and balance is reached again so that the liquid matrix in the first body 100 no longer continues to be added to the second liquid storage chamber 328. In use, the electronic atomization device can respond to the user's inhalation, and automatically add the liquid matrix of the first body 100 to the second body 200 according to a predetermined amount during each inhalation process or during the lag period after the inhalation is completed.

[0256] 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 328 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 328 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 328 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.

Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
