Description

Atomizer and electronic atomization device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an atomizer and an electronic atomization device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release the compounds without burning.

An example of such a product is a heating device that releases a compound 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 provision articles, for example, so-called electronic atomizing devices. These electronic atomizing devices typically contain a liquid that is heated to vaporize it, producing an inhalable aerosol. Known electronic atomizing devices, such as the one described in the CN202220773164.8 patent, are characterized in that the liquid storage chamber is partitioned by a tubular member disposed in the liquid storage chamber, and the liquid substrate is sucked up by an annular liquid guiding member disposed in the tubular member, and the liquid substrate is heated by a cylindrical heating net externally wrapped by the annular liquid guiding member to generate aerosol.

The buffer space defined by the plurality of recessed features 271 prevents substantial leakage of liquid matrix from between the first liquid guiding element 50 and the first support portion 210, and on the other hand helps to regulate the rate of delivery of liquid matrix via the first liquid guiding element 50 to the atomizing assembly within the tubular member 14.

As shown in fig. 4 to 7 and 9 to 12, the bracket 20 further defines therein:

A receiving chamber 250 extending from the first support portion 210 to the second support portion 220; the receiving cavity 250 is used to receive and mount at least a portion of the tubular member 14 and/or atomizing assembly.

And, there is no flexible sealing element between the tubular element 14 and the stent 20.

According to fig. 13, the tubular element 14, after assembly, extends partly into the support 20 and partly outside the support 20; and is inserted into the aerosol delivery tube 11 by the portion of the tubular element 14 located outside the holder 20 to form a tight fit connection.

In the embodiment shown in fig. 7 and 13, at least part of the perforations 142 and/or indentations 141 of the assembled tubular element 14 are located outside the stent 20; and, the first liquid guiding element 50 surrounds and covers at least part of the perforations 142 and/or indentations 141 of the tubular element 14, thereby transferring the liquid matrix from the inner surface of the plug aperture 51 of the first liquid guiding element 50 to the atomizing assembly located within the tubular element 14. In some embodiments, perforations 142 may have a diameter of approximately 2-8 mm.

As shown in fig. 4 to 7 and 9 to 12, on the sealing arrangement between the bracket 20 and the housing 10, a first sealing member mounting groove 211 is arranged on the first support portion 210 circumferentially surrounding the first support portion 210; the second support portion 220 is wrapped with a flexible absorbent element 60; and, the third support portion 230 has a second sealing member mounting groove 231 thereon circumferentially surrounding the third support portion 210; further, the liquid matrix oozing out from the gap between the housing 10 and the holder 20 is gradually blocked by the installation of the sealing member such as an O-ring in the first sealing member installation groove 211, the absorption member 60, and the installation of the sealing member such as an O-ring in the second sealing member installation groove 231, thereby achieving a sealing effect against the outflow of the liquid matrix.

In some embodiments, the absorbent element 60 is flexible; and, the absorbent element 60 is porous, e.g., the absorbent element 60 is made of a flexible porous capillary fiber material; such as a sponge with microporous pores therein, cellocotton, etc.

As shown in fig. 4 to 7 and 9 to 12, a plurality of air grooves 221 circumferentially surrounding the second support portion 220 and flanges 222 between the adjacent air grooves 221 are further arranged in addition to the second support portion 220 of the bracket 20. After assembly, the absorbent element 60 is abutted and supported by the flange 222; and a space or gap is maintained between the absorbent member 60 and the second support section 220 by the air grooves 221 to maintain an excessively absorbed liquid matrix on the absorbent member 60.

As shown in fig. 4 to 7 and 9 to 12, an air intake passage is arranged on the bracket 20 to provide a passage for air of the air inlet 22 into the accommodating chamber 250. The complete intake passage includes:

a first channel portion 23 extending from the air inlet 22 in the longitudinal direction of the bracket 20 or penetrating into an air groove 221 of the surface of the second support portion 220; the first channel portion 23 further defines a first communication port 24 of an air groove 221 located at the surface of the second support portion 220; the outside air taken in from the air inlet 22 is released from the first communication port 24 into the air groove 221 after passing through the first passage portion 23;

an air groove 221;

a second channel portion 25 extending from the air groove 221 of the surface of the second support portion 220 to or through to the receiving chamber 250 for delivering air to the atomizing assembly within the receiving chamber 250; the second channel portion 25 may include a plurality of bent sections, for example, in fig. 11 the second channel portion 25 includes a first section 252 penetrating from the second communication port 251 radially from the surface of the second support portion 220 into the second support portion 220, and a second section 253 extending longitudinally from the first section 252 to the receiving cavity 250; the second passage portion 25 has a second communication port 251 located in the air groove 221 of the surface of the second support portion 220.

In the suction, as shown by an arrow R2 in fig. 7 to 12, the outside air taken in from the air inlet 22 flows into the air groove 221 of the surface of the second supporting portion 220 through the first passage portion 23, and then flows to the second passage portion 25 through the second groove 22; finally, from the second channel portion 25, into the tubular element 14 and carries the aerosol generated by the atomizing assembly from the aerosol delivery tube 11 to the air outlet 113.

According to fig. 11, the first communication ports 24 of the first passage portion 23 are arranged opposite to the second communication ports 251 of the second passage portion 25 in the radial direction of the bracket 20; and, in the longitudinal direction of the bracket 20, the first communication port 24 of the first channel portion 23 and the second communication port 251 of the second channel portion 25 are at different longitudinal heights. In particular in fig. 11, a longitudinal distance d1 of the first communication port 24 from the lower end of the holder 20 that is greater than a longitudinal distance d2 of the second communication port 251 from the lower end of the holder 20 is advantageous for preventing aerosol condensate of the receiving chamber 250 from flowing against the airflow path toward the air intake port 22. Alternatively, the first communication port 24 is closer to the upper end of the holder 20 and/or the first fluid conducting element 50 and/or the fluid reservoir 12 than the second communication port 251.

As shown in fig. 7 to 12, the bracket 20 further defines:

a ventilation channel for providing a flow path for air into the reservoir 12; so that air can enter the reservoir 12 via the ventilation channel to relieve or eliminate the negative pressure in the reservoir 12 when the liquid matrix in the reservoir 12 gradually depletes such that the negative pressure in the reservoir 12 is below a preset threshold. Specifically, the ventilation channel includes:

a ventilation hole 261 penetrating the first support portion 210 in the longitudinal direction; specifically, the through hole 261 is left off the second support portion 220;

a ventilation groove 262 disposed on the upper surface of the first support portion 210 adjacent to the first liquid guiding member 50; and, the ventilation groove 262 extends from the ventilation hole 261 to an edge of the first support portion 210.

In an embodiment, the vent 261 has a diameter of about 0.3-2.0 mm; and, vent slots 262 have a width and/or depth of approximately 0.3-2.0 mm. When the negative pressure in the liquid storage cavity 12 is lower than the preset threshold value, as shown by an arrow R3 in fig. 7 and 11, air enters the liquid storage cavity 12 through the gap between the first liquid guiding element 50 and the housing 10 after passing through the vent hole 261 and the vent groove 262 in sequence, so that the negative pressure in the liquid storage cavity 12 is eliminated or relieved.

As shown in fig. 4 to 12, the absorbent element 60 is non-closed in the circumferential direction; the absorbent member 60, which in turn wraps or surrounds the second support portion 220, has a notch 61 extending longitudinally through the absorbent member 60; and, the inlet of the vent 261 is opposite to the notch 61, so that the air of the notch 61 enters the liquid storage chamber 12.

As shown in fig. 4 to 12, the bracket 20 is further provided with:

contact holes 241 extend through from the exposed surface in the third support portion 230 into the third support portion 230 for receiving and retaining the electrical contacts 21. Correspondingly, a wire guide 281 is also arranged in the holder 20, which extends from the receiving chamber 250 to the contact hole 241; after assembly, the conductive pins 41 and 42 of the heating element 40 extend through the wire guide 281 and into the contact holes 241, thereby making contact with the electrical contacts 21 or soldering or the like.

As shown in fig. 4, 7 and 13, the atomizer 100 having the above structure is advantageous for modular assembly; specifically, in the modular preparation and assembly, the absorbent member 60 can be wrapped around and bonded to the support frame 20, and then the tubular member 14 with the atomizing assembly contained therein can be inserted into the receiving chamber 250 of the support frame 20 to obtain the assembled state shown in fig. 13; then, as indicated by arrow P2 in fig. 13, the first liquid guiding element 50 passes through the tubular element 14 and abuts against the upper surface of the support 20, so as to obtain the module 300 shown in fig. 4. Finally, the module 300 is inserted into the housing 10 from the distal end 120 of the housing 10, as indicated by arrow P1 in fig. 4, and the tubular element 14 is tightly coupled to the aerosol output tube 11 in the housing 10, thereby obtaining the assembled atomizer 100 in fig. 7.

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 polymeric material, such that both the aerosol delivery tube 11 and the housing 10 are transparent. And the portion 14a of the tubular element 14 that protrudes outside the first liquid guiding element 50 is visible through the surface of the housing 10 after insertion of the tubular element 14 into the aerosol delivery tube 11 during or after assembly. In turn, it is advantageous to check or monitor whether the tubular element 14 is inserted correctly into the aerosol delivery tube 11 and connected securely during assembly.

And as shown in figures 4 and 13, the indentations 141 and perforations 142 of the tubular member 14 are not exposed outside the first liquid guiding element 50. The indentations 141 and perforations 142 of the tubular element 14 are substantially covered by the first liquid guiding element 50 after assembly.

In some embodiments, the notch 141 of the tubular member 14 is an operating space for installing an atomizing assembly within the tubular member 14 during manufacture. In particular, fig. 14 and 15 are schematic illustrations of the installation and assembly of an atomizing assembly within the tubular member 14; in fig. 14, as indicated by arrow P3, a sheet-like precursor, such as a sheet-like fibrous material precursor 30a, prepared to form the second liquid guiding element 30 is first wound around the heating element 40 to form the state shown in fig. 15, the wound precursor 30a also having an excess portion 310a. Then, as indicated by arrow P4 in fig. 15, the precursor 30a wrapped around the heating element 40 is inserted into the tubular member 14, and the excess portion 310a is fitted in alignment with the notch 141 of the tubular member 14 so that the excess portion 310a protrudes from the notch 141 to the outside of the tubular member 14; finally, the excess portion 310a is cut off by a tool such as scissors, thereby forming an atomizing assembly that is fully received and assembled within the tubular member 14.

It should be noted that the description and drawings of the present application show preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the appended claims.
