Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device, a first body, and a second body. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made 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 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 providing products, for example, so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or a fragrance and / or an aerosol-generating substance (e.g., glycerol). Known electronic atomization devices replenish a liquid matrix to a reusable main body through an independently replaceable liquid source. Utility Model Content

[0245] In some embodiments, the second module 400b can be pre-assembled with the container 500, which is advantageous for assembly within the first body 100. For example, the second module 400b and the container 500 are first assembled and inserted into the closure member 18 from the lower side of the closure member 18 toward the distal end 120 for installation; then, the first module 400a is inserted through the assembly hole 161 on the base 16 and into the second module 400b.

[0247] in, Figure 15 This is a schematic diagram of the liquid pumping mechanism 400 in its initial state when the user does not press the liquid pumping mechanism 400. In the initial state, the shielding element 47 is in a closed position. In the initial state, the shielding element 47 is longitudinally held between the flange 44 and the flange 462 of the piston 46. The shielding element 47 simultaneously blocks or closes the ventilation hole 456 and the second liquid inlet 463. In the initial state, the shielding element 47 is spaced apart from the connecting element 42; the connecting element 42 is not inserted into the insertion port 473 of the shielding element 47. In the initial state, the elastic element 43 is in an extended state. In the initial state, the operating element 41 protrudes from the first shell 10 at the proximal end 110. In the initial state, the valve body portion 492 of the valve element 49 is in a closed state.

Figure 16 As shown, the shielding element 47 is still in the closed position. Figure 16 As shown in FIG, the connecting element 42 moves the first stroke P11 and is inserted into the insertion port 473 of the shielding element 47, and abuts against the shielding element 47. Figure 16As shown in , after the piston 46 moves the first stroke P11 toward the liquid cache chamber 510, the flange 462 of the piston 46 separates from the shielding element 47, and a first distance d11 is generated between them; and the second liquid inlet 463 of the piston 46 moves to be offset from the shielding element 47 and extends into the liquid cache chamber 510 to be exposed. At this time, the second liquid inlet 463 of the piston 46 is in an open state; part of the volume of the liquid cache chamber 510 is compressed or occupied by the piston 46, and part of the liquid matrix in the liquid cache chamber 510 can enter the piston 46 through the second liquid inlet 463. Figure 16 In the state shown, the ventilation hole 456 / ventilation channel is still blocked or closed by the blocking element 47. Figure 16 In the state shown, the valve body portion 492 of the valve element 49 is in a closed state. Figure 16 As shown, the elastic element 43 is in a first compressed state. The length L1 of the elastic element 43 in the first compressed state = L0 - first stroke P11 , wherein L0 is the length of the elastic element 43 in the extended state or the original length.

[0249] in, Figure 17 Is the user Figure 16 Schematic diagram of the operation element 41 which has moved the first stroke P11 further being pressed to move it to the second stroke P12; Figure 17 As shown in , due to the user's further pressing operation, the piston 46 further moves the second stroke P12 in the liquid cache chamber 510 toward the distal end 120, so that the volume of the liquid cache chamber 510 is further compressed or occupied by the piston 46. Then, more liquid matrix in the liquid cache chamber 510 can enter the piston 46 through the second liquid inlet 463, and pass through the piston 46 and then be discharged or pumped out from the liquid outlet 411 into the first liquid storage chamber 14, as shown in FIG. Figure 17 As shown by arrow R3. Figure 17 As shown, when the user continues to press the operating element 41 to move it to the second stroke P12, the connecting element 42 abuts against and drives the shielding element 47 to move toward the distal end 120, thereby opening the ventilation hole 456 / ventilation channel.

Of course, in the embodiment, the power for pumping or transferring the liquid matrix in the liquid buffer chamber 510 to the liquid outlet 411 is generated by the piston 46 compressing or occupying the volume of the liquid buffer chamber 510.

[0252] In an embodiment, the liquid pumping channel is separated or isolated from the ventilation hole 456 / ventilation channel. In an embodiment, the liquid pumping channel is defined by multiple components. In an embodiment, the liquid pumping channel is from the second liquid inlet 463 of the piston 46 to the liquid outlet 411. Specifically, in an embodiment, the liquid pumping channel includes the inner hollow of the piston 46, the partial hollow of the connecting element 42, and the partial hollow of the operating element 41. Or in this embodiment, the liquid pumping channel is at least partially defined by the piston 46. Or in some other embodiments, a longitudinally extending groove structure can also be formed or defined on the outer surface of the piston 46, and the liquid pumping channel is at least partially formed or provided by these groove structures.

When the elastic element 43 is in the second compressed state, it is Figure 16 The first compressed state is further compressed. The length L2 of the elastic element 43 in the second compressed state is equal to L1 - the second stroke P12.

Figure 18 As shown in the figure, the connecting element 42 is moved by the third stroke P13 toward the proximal end 110, and after the movement, the connecting element 42 is removed from the shielding element 47 and separated from the shielding element 47; and, the piston 46 is moved by the third stroke P13 toward the proximal end 110, and after the movement, the flange 462 of the piston 46 abuts against the shielding element 47; and, the second liquid inlet 463 of the piston 46 is again blocked and closed by the shielding element 47.

[0256] exist Figure 18During the movement shown, due to the movement of the piston 46, the volume of the liquid cache chamber 510 occupied by the piston 46 is released again, thereby forming a negative pressure in the liquid cache chamber 510; thereby, a pressure difference is generated between the liquid cache chamber 510 and the second liquid storage chamber 510, causing the valve body portion 492 of the valve element 49 to bend or deform toward the liquid cache chamber 510 to open the first liquid inlet 455; then, part of the liquid matrix in the second liquid storage chamber 510 is replenished or enters the liquid cache chamber 510 through the extension tube 48 and the first liquid inlet 455, as shown in FIG. Figure 18 At the same time, the ventilation hole 456 / ventilation channel is opened by the shielding element 47. When part of the liquid matrix of the second liquid storage chamber 510 is added to the liquid buffer chamber 510, the air in the first liquid storage chamber 14 enters the container 500 / second liquid storage chamber 510 through the ventilation hole 456 / ventilation channel. Figure 18 As shown by the arrow R5, the pressures are adjusted or balanced. Figure 18 In the embodiment of the present invention, the movement of the piston 46 toward the proximal end 110 forms a negative pressure in the liquid cache chamber 510; when the pressure difference between the liquid cache chamber 510 and the second liquid storage chamber 510 exceeds a predetermined threshold, the valve body portion 492 of the valve element 49 bends or deforms toward the liquid cache chamber 510 to open the first liquid inlet 455, so that part of the liquid matrix of the second liquid storage chamber 510 is replenished into the liquid cache chamber 510, as shown in FIG. Figure 18 As shown by arrow R4 , when the pressure difference between the liquid buffer chamber 510 and the second liquid storage chamber 510 is balanced or lower than the predetermined threshold again, the valve body portion 492 of the valve element 49 returns to the state before bending or deformation to close the first liquid inlet 455 .

[0257] when Figure 18 The distance of the third stroke P13 is substantially equal to the first distance d11 / first stroke P11. At this point, the elastic element 43 is at least partially released from the second compressed state to the third compressed state. The length of the elastic element 43 in the third compressed state is longer than in the second compressed state; alternatively, the second compressed state is more compressed than the third compressed state. The length L3 of the elastic element 43 in the third compressed state = L2 + third stroke P13.

When the elastic element 43 drives the piston 46 to move from the second position to the first position, the liquid pumping channel and / or the second liquid inlet 463 of the piston 46 are closed earlier than the ventilation channel / ventilation hole 456.

[0260] In an embodiment, the elastic element 43 is arranged to move the movable operating element 41 and / or the connecting element 42 and / or the piston 46 and / or the shielding element 47 toward Figure 15 Alternatively, the resilient element 43 is arranged to bias the piston 46 and / or the connecting element 42 towards the first position.
