Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and particularly to an electronic atomization device. Background Art

[0002] During use, tobacco products (such as cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke. People have tried to replace these tobacco-burning products by creating products that release compounds without burning.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material can be tobacco or other non-tobacco products, which may or may not contain nicotine.

These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol.

Known electronic atomization devices generate an aerosol by atomizing the liquid received from a first liquid storage chamber by an atomization assembly, and gradually replenish the liquid in the first liquid storage chamber with a smaller liquid storage capacity from a second liquid storage chamber with a larger liquid storage capacity.

In use, a biasing force is provided by the elastic restoring force of the elastic element 53, enabling the container 52 to move from the second position to the first position and / or biasing the container 52 towards the first position.

[0155] According to Figures 2 to 7 shown in [reference document], a abutting step 1191 is arranged on the inner surface of the cavity 119; when the container 52 and / or the second liquid storage chamber 520 are in the first position, the second part 522 of the container 52 longitudinally abuts against the abutting step 1191 to provide a limit.

[0157] In the embodiment, the second liquid storage chamber 520 is movable. The second liquid storage chamber 520 is closer to the proximal end 110 in the first position than in the second position.

[0158] According to Figure 8 and Figure 9 shown in [reference document], the second part 522 of the container 52 has a flat surface 5221. After assembly, the flat surface 5221 of the second part 522 faces or abuts against the partition wall 116. The liquid inlet 523 and the liquid outlet 524 penetrate from the second liquid storage chamber 520 to the flat surface 5221.

[0159] According to Figure 8 and Figure 9 shown in [reference document], the following are also arranged on the second part 522 of the container 52:

[0160] Sealing elements 526 and 527 arranged at intervals along the longitudinal direction; the sealing elements 526 and / or the sealing element 527 are, for example, O-rings. The sealing elements 526 and 527 are annular and arranged around the second part 522. The liquid inlet 523 and the liquid outlet 524 are located between the sealing element 526 and the sealing element 527.

[0163] In the above embodiment, the diameter of the liquid outlet 524 is smaller than the diameter of the liquid inlet 523. The number of the liquid outlets 524 is at least two. When the liquid matrix in the second liquid storage chamber 520 flows out from at least one of the liquid outlets 524 to the atomization assembly 30 / capillary element 31, at least one other liquid outlet 524 allows air to enter the second liquid storage chamber 520 to relieve or balance the pressure in the second liquid storage chamber 520.

[0164] According to Figures 2 to 5 As shown, there is a spacing space between the support element 117 and the bracket 130; the aerosol output pipe 115 extends into this spacing space. Thus, in use, the aerosol condensate falling from the aerosol output pipe 115 can be collected or received by the spacing space between the support element 117 and the bracket 130.

[0165] In the embodiment, the volume of the first liquid storage chamber 114 is larger than the volume of the second liquid storage chamber 520. The amount of the liquid matrix that the first liquid storage chamber 114 can absorb and store is larger than the amount of the liquid matrix that the second liquid storage chamber 520 can absorb and store. For example, in some specific embodiments, the first liquid storage chamber 114 can store 5 to 20 mL of the liquid matrix, more specifically, for example, 10 mL; the second liquid storage chamber 520 can store 0.5 to 3 mL of the liquid matrix, more specifically, for example, 2 mL.

[0166] In use, the user can press the operating element 51 to supplement a certain amount of the liquid matrix from the second liquid storage chamber 520 to the capillary element 31 each time an operation is performed.
