Description

Technical Field

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 electronic atomization devices generally contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. Known electronic atomization devices, such as the CN202220773164.8 patent technology, separate the liquid storage chamber by a tubular element arranged in the liquid storage chamber, and absorb the liquid matrix by an annular liquid-conducting element arranged in the tubular element, and heat the liquid matrix by a cylindrical heating net wrapped from the outside by the annular liquid-conducting element to generate an aerosol.

[0149] The outer diameter of the second support portion 220 is smaller than the outer diameters of the first support portion 210 and the third support portion 230 ; thus, the second support portion 220 is recessed relative to the first support portion 210 and the third support portion 230 .

[0150] After assembly, the first support portion 210 abuts against and supports the first liquid-conducting element 50. The second support portion 220 is wrapped or surrounded by the absorption element 60, and the absorption element 60 is supported from the inside by the second support portion 220. The third support portion 230 establishes a mechanical connection and interference fit with the housing 10 near the distal end 120; specifically, a connection structure 232 such as a card slot or a card protrusion can be arranged on the third support portion 230 to establish a mechanical connection with the housing 10.

[0151] according to Figures 4 to 7 , Figures 9 to 12 As shown, the first support portion 210 of the bracket 20 is adjacent to or supports the upper end surface of the first liquid-conducting element 50 and is provided with a plurality of recessed structures 271; the recessed structures 271 define a buffer space between the first support portion 210 and the second surface 520 of the first liquid-conducting element 50, so as to buffer the liquid matrix that seeps out from the second surface 520 of the first liquid-conducting element 50. The buffer space defined by the plurality of recessed structures 271 prevents a large amount of liquid matrix from leaking from between the first liquid-conducting element 50 and the first support portion 210, and on the other hand, helps to regulate the rate of transferring the liquid matrix from the first liquid-conducting element 50 to the atomizing assembly in the tubular element 14 to be stable.

[0152] according to Figures 4 to 7 , Figures 9 to 12 As shown, the bracket 20 also defines:

[0153] The accommodating cavity 250 extends from the first supporting portion 210 to the second supporting portion 220; the accommodating cavity 250 is used to accommodate and install at least part of the tubular element 14 and / or the atomizing assembly. Specifically, after assembly, at least part of the tubular element 14 is inserted into the accommodating cavity 250 of the bracket 20; and the tubular element 14 and the bracket 20 are sealed by interference fit. In addition, there is no flexible sealing element between the tubular element 14 and the bracket 20.

[0154] according to Fig.13 As shown, after assembly, the tubular element 14 partially extends into the bracket 20 and partially is located outside the bracket 20; and the portion of the tubular element 14 located outside the bracket 20 is inserted into the aerosol output tube 11 to form a tight fit.

[0155] exist Figure 7 and Fig.13 In the illustrated embodiment, at least a portion of the through hole 142 and / or the notch 141 of the tubular element 14 is located outside the support 20 after assembly; and the first liquid-conducting element 50 surrounds and covers at least a portion of the through hole 142 and / or the notch 141 of the tubular element 14, so that the liquid matrix is ​​transferred from the inner surface of the insertion hole 51 of the first liquid-conducting element 50 to the atomizing assembly located in the tubular element 14. In some embodiments, the through hole 142 may have a diameter of about 2 to 8 mm.

[0156] according to Figures 4 to 7 , Figures 9 to 12 As shown, in the sealing arrangement between the bracket 20 and the housing 10, a first sealing element installation groove 211 is arranged on the first support part 210 along the circumferential direction surrounding the first support part 210; the second support part 220 is wrapped with a flexible absorption element 60; and a second sealing element installation groove 231 is arranged on the third support part 230 along the circumferential direction surrounding the third support part 210; and then the sealing element such as an O-ring installed in the first sealing element installation groove 211, the absorption element 60, and the sealing element such as an O-ring installed in the second sealing element installation groove 231 gradually prevent the liquid matrix from seeping out of the gap between the housing 10 and the bracket 20, thereby achieving a sealing effect of preventing the liquid matrix from flowing out.

[0157] In some embodiments, the absorption element 60 is flexible; and, the absorption element 60 is porous, for example, the absorption element 60 is made of a flexible porous capillary fiber material; for example, a sponge or fiber cotton having microporous pores inside.

[0158] according to Figures 4 to 7 , Figures 9 to 12 As shown, the second support portion 220 of the bracket 20 is further provided with a plurality of air grooves 221 circumferentially surrounding the second support portion 220, and flanges 222 located between adjacent air grooves 221. After assembly, the flanges 222 abut against and support the absorption element 60; and the air grooves 221 maintain a spacing or gap between the absorption element 60 and the second support portion 220, so as to retain the excessively absorbed liquid matrix on the absorption element 60.

[0159] according to Figures 4 to 7 , Figures 9 to 12As shown, an air inlet passage is arranged on the bracket 20 to provide a passage for the air from the air inlet 22 to enter the accommodating cavity 250. The complete air inlet passage includes:

[0160] The first channel portion 23 extends from the air inlet 22 along the longitudinal direction of the bracket 20 or penetrates into the air groove 221 on the surface of the second support portion 220; the first channel portion 23 also defines a first communication port 24 located in the air groove 221 on the surface of the second support portion 220; the external air entering from the air inlet 22 passes through the first channel portion 23 and is released from the first communication port 24 into the air groove 221;

[0161] Air groove 221;

[0162] The second channel portion 25 extends from the air groove 221 on the surface of the second support portion 220 to or penetrates the accommodating chamber 250, so as to deliver air to the atomizing assembly in the accommodating chamber 250; the second channel portion 25 may include a plurality of bent sections, for example, Fig.11 The second channel portion 25 includes a first section 252 radially extending from the surface of the second support portion 220 to the inside of the second support portion 220 from the second connecting port 251, and a second section 253 extending longitudinally from the first section 252 to the accommodating cavity 250; the second channel portion 25 has a second connecting port 251 located in the air groove 221 on the surface of the second support portion 220.

[0163] During suction, the airflow path is shown in Figures 7 to 12 As shown by the middle arrow R2, the external air entering from the air inlet 22 flows into the air groove 221 on the surface of the second support part 220 through the first channel part 23, and then flows to the second channel part 25 through the second groove 22; finally, it enters the tubular element 14 from the second channel part 25, and carries the aerosol generated by the atomization component to be delivered from the aerosol output tube 11 to the air outlet 113.

[0164] according to Fig.11 As shown, along the radial direction of the bracket 20, the first communication opening 24 of the first channel portion 23 is arranged opposite to the second communication opening 251 of the second channel portion 25; and along the longitudinal direction of the bracket 20, the first communication opening 24 of the first channel portion 23 and the second communication opening 251 of the second channel portion 25 are at different longitudinal heights. Fig.11 In the embodiment, the longitudinal distance d1 between the first communication port 24 and the lower end of the bracket 20 is greater than the longitudinal distance d2 between the second communication port 251 and the lower end of the bracket 20, which is beneficial for preventing the aerosol condensate in the accommodating chamber 250 from flowing against the air flow path toward the air inlet 22. Alternatively, the first communication port 24 is closer to the upper end of the bracket 20 and / or the first liquid guiding element 50 and / or the liquid storage chamber 12 than the second communication port 251.

[0165] according to Figures 7 to 12 As shown, the bracket 20 is also defined by:

[0166] The ventilation channel is used to provide a flow path for air to enter the liquid storage chamber 12; so that when the liquid matrix in the liquid storage chamber 12 is gradually consumed and the negative pressure in the liquid storage chamber 12 is lower than a preset threshold, air can enter the liquid storage chamber 12 through the ventilation channel to relieve or eliminate the negative pressure in the liquid storage chamber 12. Specifically, the ventilation channel includes:

[0167] The vent hole 261 penetrates the first support portion 210 in the longitudinal direction; specifically, the vent hole 261 avoids the second support portion 220;

[0168] The ventilation groove 262 is arranged on the upper surface of the first supporting portion 210 adjacent to the first liquid guiding element 50 ; and the ventilation groove 262 extends from the ventilation hole 261 to the edge of the first supporting portion 210 .

[0169] In an embodiment, the vent hole 261 has a diameter of about 0.3 to 2.0 mm; and the vent groove 262 has a width and / or depth of about 0.3 to 2.0 mm. When the negative pressure in the liquid storage chamber 12 is lower than a preset threshold, such as Figure 7 and Fig.11 As shown by the middle arrow R3 , air passes through the vent hole 261 and the vent groove 262 in sequence, and then enters the liquid storage chamber 12 through the gap between the first liquid guiding element 50 and the housing 10 , thereby eliminating or relieving the negative pressure in the liquid storage chamber 12 .

[0170] according to Figures 4 to 12 As shown, the absorption element 60 is non-closed in the circumferential direction; the absorption element 60 that wraps or surrounds the second support portion 220 has a gap 61 that passes through the absorption element 60 longitudinally; and the entrance of the vent 261 is opposite to the gap 61, so that the air in the gap 61 enters the liquid storage chamber 12.

[0171] according to Figures 4 to 12 As shown, the bracket 20 is also provided with:

[0172] The contact hole 241 penetrates from the exposed surface in the third support part 230 to the inside of the third support part 230, so as to accommodate and hold the electric contact 21. Accordingly, the bracket 20 is also provided with a wire hole 281 penetrating from the accommodating cavity 250 to the contact hole 241; after assembly, the conductive pins 41 and 42 of the heating element 40 penetrate the wire hole 281 and then extend into the contact hole 241, and then contact or weld with the electric contact 21 to form electrical conduction.

[0173] according to Figure 4 , Figure 7 and Fig.13As shown, the atomizer 100 having the above structure is advantageous for modular assembly; specifically, in the modular preparation and assembly, the absorption element 60 can be first wrapped and combined with the bracket 20, and then the tubular element 14 containing the atomization component inside is inserted into the accommodating cavity 250 of the bracket 20 to obtain Fig.13 The assembly state shown; then Fig.13 As shown by the middle arrow P2, the first liquid-conducting element 50 passes through the tubular element 14 and abuts against the upper surface of the bracket 20 to obtain Figure 4 Finally, according to the module 300 Figure 4 As shown by the arrow P1, the module 300 is inserted into the housing 10 from the distal end 120 of the housing 10, and the tubular element 14 is tightly coupled to the aerosol output tube 11 in the housing 10, thereby obtaining Figure 7 The assembled atomizer 100 is shown in FIG.

[0174] In some embodiments, the aerosol delivery tube 11 is integrally molded with the housing 10 from a moldable material; and in an embodiment, the aerosol delivery tube 11 and the housing 10 are molded from a transparent polymer material, thereby making the aerosol delivery tube 11 and the housing 10 both transparent. And during or after assembly, after the tubular element 14 is inserted into the aerosol delivery tube 11, the portion 14a of the tubular element 14 extending out of the first liquid guiding element 50 is visible through the surface of the housing 10. Therefore, during assembly, it is advantageous to check or monitor whether the tubular element 14 is correctly inserted into the aerosol delivery tube 11 and is securely connected.

[0175] And according to Figure 4 and Fig.13 As shown, the notch 141 and the through hole 142 of the tubular element 14 are not exposed outside the first liquid-conducting element 50. After assembly, the notch 141 and the through hole 142 of the tubular element 14 are substantially covered by the first liquid-conducting element 50.

[0176] In some embodiments, the notch 141 of the tubular element 14 is an operating space for installing the atomizing assembly in the tubular element 14 during preparation. Specifically, Fig.14 and Fig.15 A schematic diagram of installing and assembling the atomizing assembly in the tubular element 14; Fig.14 As shown by the middle arrow P3, the sheet precursor for preparing the second liquid conducting element 30, for example, the sheet fiber material precursor 30a, is firstly wound around the heating element 40 to form a Fig.15 In the state shown in FIG. 1 , the wound precursor 30a still has an excess portion 310a. Fig.15As shown by the middle arrow P4, the precursor 30a wrapped with the heating element 40 after being rolled is inserted into the tubular element 14, and the excess portion 310a is aligned with the notch 141 of the tubular element 14 so that the excess portion 310a extends out of the tubular element 14 from the notch 141; finally, the excess portion 310a is cut off with a tool such as scissors, thereby forming an atomization component that is completely contained and assembled in the tubular element 14.
