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. 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 electronic atomization devices typically contain a liquid that is heated by an atomization component to vaporize it, thereby producing an inhalable aerosol. Known electronic atomization devices surround and support the atomization component by a bracket; when the pressure in the liquid storage chamber is greater than the external pressure, the liquid matrix adsorbed and retained by the atomization component will leak outward or into the airflow channel.

In this embodiment, the extension dimension of the sealing sleeve 94 in the axial direction is greater than the thickness in the radial direction.

[0152] In the embodiment, the sealing sleeve 94 is molded and combined with the base 90; specifically, in the embodiment, the sealing sleeve 94 and the base 90 are directly prepared and combined by two-color injection molding.

[0156] according to Fig. 9 , Fig.12 and Fig.13 As shown, the bracket 60 also includes:

[0157] At least one or more connecting holes 624 extend from the second section 612 of the first accommodating cavity 610 to the storage space 622 , so as to connect at least a portion of the surface of the first liquid-conducting element 52 accommodated in the second section 612 with the storage space 622 .

[0158] In the embodiment, the connecting hole 624 connects only the second section 612 of the first accommodating cavity 610 to the storage space 622. The connecting hole 624 avoids the first section 611 of the first accommodating cavity 610 and the third liquid guiding element 51. Also, the connecting hole 624 avoids the third section 613 of the first accommodating cavity 610.

[0159] When the first liquid guiding element 52 is accommodated in the second section 612 of the first accommodation cavity 610 , the outer surface of the first liquid guiding element 52 abuts against and fits the inner surface of the second section 612 . Also, the outer surface of the first liquid guiding element 52 shields and covers the communication hole 624 .

[0160] In the embodiments, Figures 9 to 13As shown by the middle arrow R4, when the pressure in the liquid storage cavity 112 is greater than the external pressure, the liquid matrix absorbed and retained in the first liquid guiding element 52 can flow through the connecting hole 624 to the storage space 622, and be adsorbed and retained in the storage space 622; and in use, the storage space 622 can buffer the liquid matrix supersaturatedly adsorbed by the first liquid guiding element 52. And when the pressure in the liquid storage cavity 112 is less than the external pressure, the liquid matrix that has seeped into the storage space 622 flows back through the connecting hole 624 and is reabsorbed by the first liquid guiding element 52. The storage space 622 has a width of about 0.5 mm to 3.0 mm.

[0161] according to Figures 9 to 13 As shown in , the communicating holes 624 include a plurality of communicating holes; at least two communicating holes 624 are spaced apart in the longitudinal direction of the bracket 60.

Specifically, for example, the communicating holes 624 include a first communicating hole and a second communicating hole; the two different storage spaces 622 include a first air groove and a second air groove. The first communicating hole and the second communicating hole are at different heights in the longitudinal direction of the bracket 60, and the first air groove and the second air groove are at different heights in the longitudinal direction of the bracket 60; the first communicating hole penetrates to the first air groove, and the second communicating hole penetrates to the second air groove.

[0162] according to Figures 9 to 13 As shown, the bracket 60 is also defined by:

[0163] The ventilation channel 67 is used to provide a flow path for air to enter the liquid storage chamber 112 when the negative pressure in the liquid storage chamber 112 exceeds a predetermined threshold. Specifically, the ventilation channel 67 includes:

[0164] The ventilation compartment 673 located on the outer surface of the bracket 60 is surrounded and defined by partition walls 674 arranged at intervals along the circumference of the bracket 60; the ventilation compartment 673 is defined between the partition flange 621 closest to the first end and the first end of the bracket 60;

[0165] A first ventilation slot 671 extending from the ventilation compartment 673 to a first end of the bracket 60;

[0166] The second ventilation groove 672 is located on the surface of the first end of the bracket 60 and extends radially from the first ventilation groove 671 to the first section 611 of the first accommodating chamber 610. When the negative pressure in the liquid storage chamber 112 exceeds a predetermined threshold, the air in the ventilation compartment 673 passes through the first ventilation groove 671 and the second ventilation groove 672 in sequence and then enters the liquid storage chamber 112. Figures 9 to 12 As shown by the arrow R3.

[0167] In this embodiment, the depth or width of the first ventilation groove 671 is between 0.2 mm and 1.5 mm; the width or depth of the second ventilation groove 672 is greater than the depth or width of the first ventilation groove 671, for example, the width or depth of the first ventilation groove 671 is between 2 mm and 4 mm. The width of the ventilation compartment 673 is greater than the width of the second ventilation groove 672, for example, the width of the ventilation compartment 673 is between 4 mm and 8 mm. The increased width of the ventilation compartment 673 can make the ventilation compartment 673 have a spatial volume greater than the first ventilation groove 671 and / or the second ventilation groove 672, and can be used to store the liquid matrix that seeps out from the liquid storage chamber 112 through the ventilation channel 67.

[0168] according to Figures 9 to 13 As shown in the figure, the ventilation compartment 673 is connected to the air compartment 97 in the base 90 through the plurality of storage spaces 622; and because the plurality of storage spaces 622 are connected through the notch 623 on the partition flange 621, the communication path between the ventilation compartment 673 and the air compartment 97 extends in a circuitous or tortuous manner in the plurality of storage spaces 622, for example Fig.12 As shown by the arrow R5.

[0169] In an embodiment, the ventilation compartment 673 of the ventilation channel 67 is in airflow communication with the air compartment 97 of the base 90 , and further in airflow communication with a portion of the airflow channel passing through the base 90 , so that external air is replenished into the liquid storage chamber 112 .

[0170] In some embodiments, when the pressure in the liquid storage chamber 112 is greater than the external pressure, part of the liquid matrix in the liquid storage chamber 112 flows outwardly through the ventilation channel 67 to the ventilation compartment 673 and / or the storage space 622. Also, when the pressure in the liquid storage chamber 112 is less than the external pressure, for example, during air transportation or product testing, the liquid matrix overflowing from the ventilation channel 67 and buffered in the ventilation compartment 673 and / or the storage space 622 can flow back through the connecting hole 624 and be absorbed by the first liquid guiding element 52 again.

[0171] according to Figures 9 to 11 As shown, when the bracket 60 is accommodated and installed in the base 90, in order to maintain the airflow communication between the storage space 622 of the bracket 60 and the air compartment 97 of the base 90, at least one or more supporting protrusions 921 are arranged on the inner bottom wall of the second accommodating cavity 92 of the base 90; when the bracket 60 is accommodated and installed in the second accommodating cavity 92, it abuts against the supporting protrusions 921 in the longitudinal direction, and then maintains a gap d11 between the inner bottom wall of the second accommodating cavity 92, and forms airflow communication with the air compartment 97 through the gap d11 therebetween. The gap d11 is about 1 mm to 3 mm.
