Description

Atomizer, electronic atomization device and atomization assembly

Technical Field

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

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 compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning the material. For example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. As another example, there are aerosol-providing articles, e.g. so-called electronic nebulizing devices. These devices typically contain a liquid that is heated to vaporize it, thereby generating an inhalable aerosol.

For the known electronic atomization device, when the volume of air in the liquid storage cavity is gradually increased along with the gradual consumption reduction of liquid in the liquid storage cavity in use, the liquid in the liquid storage cavity is difficult to maintain at a proper negative pressure; leakage of the liquid matrix is likely to occur when the internal pressure of the reservoir chamber increases above the external air pressure or the external air pressure decreases below the internal pressure of the reservoir chamber.

After installation, the complete suction airflow path is shown by an arrow R2 in fig. 3 and 4, the external air enters into the atomizing chamber 340 through the first air inlet 23 on the end cap 20, and then the generated aerosol is carried to the second jack 62 from the aerosol output channel 63, and then is output to the smoke transmission tube 11 through the first jack 72.

As further shown in fig. 6 and 7, the porous body 30 is configured in a square tube shape substantially perpendicular to the longitudinal direction of the main casing 10; comprising:

first and second walls 32 and 31 facing away from each other in the longitudinal direction of the main casing 10;

a suction surface 320 formed by at least a portion of the outer surface of the first wall 32; the liquid absorbing surface 320 is at least partially opposite to the third liquid guiding hole 51, and further absorbs the liquid substrate flowing down from the liquid channel indicated by the arrow R1;

the atomizing surface 310 is formed by at least part of the outer surface of the second wall 31; the atomizing surface 310 forms a heating element 40 for heating the liquid substrate;

a liquid buffer chamber 33 between the first wall 32 and the second wall 31 in the longitudinal direction of the main housing 10 for storing the liquid medium. Structurally, the liquid-buffering chamber 33 penetrates the porous body 30 in the axial direction of the porous body 30.

Of course, as shown in FIG. 7, the porous body 30 also has opposing front and rear sidewalls 38, 39; and the liquid buffer chamber 33 is defined by the front side wall 38, the rear side wall 39, the first wall 32 and the second wall 31.

In an alternative embodiment, the thickness of the front and/or rear side walls 38, 39 and/or the first and/or second walls 32, 31 is between about 0.5 mm and about 2 mm; the extension length of the front side wall 38 and/or the rear side wall 39 and/or the first wall 32 and/or the second wall 31 in the axial direction of the porous body 30 is about 6 to 10 mm.

In a further alternative embodiment, the liquid-absorbing surface 320 and atomizing surface 310 have a width d1 of about 3-6 mm, such as 3.2mm for the width d1 in FIG. 7; the width d2 of the front 38 and/or rear 39 side walls is approximately 3-7 mm, for example 3.65mm for the width d2 in FIG. 7.

The cross-sectional shape of the liquid cache chamber 33 is also roughly square in fig. 7; of course, in other alternative embodiments, the cross-sectional shape of the liquid buffer chamber 33 may be circular, elliptical, etc. The width or height of the liquid buffer chamber 33 is larger than 1.5-2 mm.

As further shown in fig. 6 and 8, after the porous body 30 is assembled with the second sealing member 50, the openings of both sides of the liquid buffer chamber 33 in the axial direction are wrapped and closed by the second sealing member 50.

According to the arrow R1 in fig. 8, in use, the liquid medium in the liquid storage chamber 12 flows from the third liquid guiding hole 51 of the second sealing member 50 to the liquid absorbing surface 320 and is absorbed by the porous body 30; then the liquid medium gradually permeates the first wall 32 through the pores in the porous body 30 and flows into the liquid buffer chamber 33, and the liquid medium is heated and atomized on the atomization surface 310 after gradually permeating the second wall 31 from the liquid buffer chamber 33.

The adoption of the porous body 30 can relieve or at least partially eliminate the influence of negative pressure change in the liquid storage cavity 12 so as to prevent the leakage of the liquid matrix through the porous body 30; referring specifically to fig. 8, when the liquid medium in the reservoir 12 is driven by the pressure difference and gravity to permeate through the porous body 30 to the atomizing chamber 340, the liquid medium is required to gradually overcome the resistance DP1 of the first wall 32 and the resistance DP2 of the second wall 31, regardless of the pressure difference generated by the liquid level height. The liquid matrix infiltrates or infiltrates into the atomizing surface 310 after passing through the first wall 32 and the second wall 31 in sequence, and the barrier provided by the first wall 32 and the second wall 31 is beneficial to reducing or eliminating the leakage of the liquid matrix, thereby improving the liquid locking capability.

A storage space for buffering the liquid medium is provided by the first liquid buffering cavity 33a and the second liquid buffering cavity 35a in use; the resistance DP11 of the first wall 32a, the resistance DP12 of the third wall 34a, and the resistance DP13 of the second wall 31a can gradually slow the leakage of the liquid matrix due to the pressure change, improving the liquid locking capability of the porous body 30 a.

In still other alternate implementations, there may be more third walls 34a, such as two, three, etc., within the porous body 30/30a to define more liquid-caching chambers within the porous body 30/30a in a spaced apart manner to prevent leakage of liquid matrix.

Alternatively, in other variations, the porous body 30/30a may have other cross-sectional shapes, such as trapezoidal, polygonal, etc.

FIG. 11 shows a schematic structural view of a porous body 30b of yet another embodiment; the porous body 30b includes a first wall 32b and a second wall 31b opposed to each other in the longitudinal direction of the main casing 10, and connecting portions 36b extending between the first wall 32b and the second wall 31b on both sides in the width direction; the first wall 32b and the second wall 31b are connected and supported by the connecting portion 36 b. In use, the upper surface of first wall 32b faces reservoir 12 and communicates with reservoir 12 to draw in liquid substrate; the lower surface of the second wall 31b acts as an atomising surface to which the heating element 40 is coupled to atomise the liquid substrate. Meanwhile, the liquid buffer chamber 33b is formed between the first wall 32b and the second wall 31b after being sealed from the surroundings by the second sealing member 50 after assembly.

Or fig. 12 shows a case where the main casing 10 is made of a first porous body 30c and a second porous body 80c in the form of a sheet arranged in this order in the longitudinal direction of the main casing 10; they are kept at a certain distance and are respectively kept fixed and sealed by the second sealing element 50; eventually with the space therebetween forming the liquid buffer chamber 33 c.
