With further reference to fig. 3-5, the interior of the main housing 10 is provided with a liquid reservoir 12 for storing a liquid matrix, and an atomizing assembly for drawing the liquid matrix from the liquid reservoir 12 and heating the atomized liquid matrix. In the schematic cross-sectional view shown in fig. 5, an aerosol output tube 11 is disposed in the main housing 10 along the axial direction, and a space between the outer wall of the aerosol output tube 11 and the inner wall of the main housing 10 forms a liquid storage cavity 12 for storing a liquid matrix; the first end of the aerosol delivery tube 11 opposite the proximal end 110 communicates with the inhalation port 111 so as to deliver the aerosol generated to the inhalation port 111 for inhalation.

The atomizing assembly is shown in fig. 3 to 5 as comprising: a second liquid guiding element 30, and a heating element 40 for heating and vaporizing the liquid matrix sucked by the second liquid guiding element 30. In particular, the second liquid guiding member 30 is made of a flexible strip or rod-like fibrous material, such as cotton fibers, nonwoven fibers, sponge, etc.; the second liquid guiding member 30 is configured in a U-shape in assembly, including a portion 31 extending in the width direction of the main casing 10, and portions 32 extending from both end sides of the portion 31 toward the liquid storage chamber 12.

When the first liquid guiding element 50a is assembled and accommodated in the accommodating portion 78a, a space is defined between the first liquid guiding element 50a and the inner surface of the holder 70a defining the holding cavity 752a, so that the portion 32 of the second liquid guiding element 30 can pass through the space to the outside of the upper side surface 510a of the first liquid guiding element 50a to define the exposed section 321, and the liquid substrate in the liquid storage cavity 12 can be directly sucked through the exposed section 321.

And as shown in fig. 11 to 13, the peripheral side wall of the first liquid guiding member 50a has a flat portion 53a; and the straight portion 53a is disposed on at least one side in the longitudinal direction of the first liquid-guiding member 50 a. In the practice of this utility model, the above gap is defined between the flat portion 53a and the inner surface of the holder 70a defining the holding cavity 752 a. And, after assembly, the portion 32 of the second liquid guiding member 30 is at least partially compressed or compressed by the flat portion 53a and is in contact with the flat portion 53a, thereby being capable of drawing the liquid matrix from the first liquid guiding member 50 a.

Further figures 14-16 show schematic views of a first liquid directing element 50b, atomizing assembly, and bracket 70b of yet another alternative embodiment; in this embodiment, end 710b of bracket 70b is open, and has a receiving cavity 78b defined by a step 77 b; in assembly, the first liquid guiding element 50b can be received or accommodated through the opening in the accommodating chamber 78b and form a stop against the step 77 b. And, the bracket 70b defines an air groove 79b on the inner surface of the receiving chamber 78b for defining an air passage with the peripheral side wall of the first liquid guiding element 50b when the first liquid guiding element 50b is received in the receiving chamber 78b to provide a flow path for air within the bracket 70b into the liquid storage chamber 12.

And in fig. 14 to 16, the holding chamber 752b defines a side opening 712b located on at least one side of the width direction of the holder 70 b; and the side opening 712b is clear of or away from the first liquid guiding element 50b and/or the receiving cavity 78 b. After assembly, the portion 32b of the second liquid guiding element 30b extends at least partially from the side opening 712b to the outside of the bracket 70b and/or the first liquid guiding element 50b, thereby forming an exposed section 321b for directly sucking up the liquid matrix of the liquid storage chamber 12.

And in the implementation shown in fig. 14 to 16, the holding chamber 752b is disposed adjacent to at least a portion of the side opening 712b to be inclined and bent outward in the width direction of the bracket 70 b; so that a partial region of the portion 32b is also inclined or curved. After the assembly, the assembly is completed, the exposed section 321b that extends beyond the support 70b is defined in part by the curved region of the portion 32 b. And in fig. 15, the exposed section 321b is in an oblique arrangement with a non-perpendicular angle to the first liquid guiding element 50 b. And, the included angle α between the exposed section 321b and the first liquid guiding element 50b is 45 ° to 85 °.

And as shown in fig. 14-16, side opening 712b is near or disposed at end 710 b; the side opening 712b or the end face 711b defining the side opening 712b is arranged obliquely toward the direction 50b approaching the liquid guiding member. And, the first liquid guiding member 50b also covers and presses the portion 32b to stably hold the portion 32b while also being able to transfer the liquid matrix to the portion 32b through contact.

Or FIGS. 17 and 18 illustrate schematic views of a first liquid directing element 50c, atomizing assembly, and a carrier 70c of yet another alternative embodiment; likewise, the holding cavity of the bracket 70c for receiving or holding the portion 32c is at least partially curved, thereby bending the portion 32c at least outwardly of the bracket 70 c.

And in figures 17 and 18 of the drawings, the bracket 70c has disposed thereon:

cut-outs or slits 711c are disposed obliquely outward from the end 710c in the width direction of the bracket 70 c; the cuts or slits 711c are formed by cutting with a blade, molding, or the like;

the movable shielding portion 712c is defined by a cutout or slit 711 c; the movable shielding portion 712c may be folded or movable in the width direction of the bracket 70c as indicated by an arrow R4 in fig. 17 and 18.

During assembly, the movable shielding portion 712c is folded outwardly to facilitate the insertion of the exposed section 321c of the portion 32c into the cutout or slit 711 c; the first liquid guiding element 50c is then received in the receiving cavity 78c of the bracket 70c such that the first liquid guiding element 50c covers or abuts the portion 32c of the second liquid guiding element 30 c. After assembly, the movable shielding portion 712c is then folded inwardly to cover at least a portion of the exposed section 321 c. And after assembly, the movable shielding portion 712c does not completely cover the exposed section 321c, thereby leaving a portion of the exposed section 321c exposed at the end 710c of the bracket 70c to directly draw the liquid matrix of the liquid reservoir 12.

And in some implementations, the width of the cuts or slits 711c is approximately between 0.5 and 2mm.

In the embodiment shown in fig. 17 and 18, the movable shielding section 712c is defined by a cut-out or slit 711c, which is advantageous for the assembly of the first liquid guiding element 50c and the atomizing assembly. And that, after assembly, the exposed section 321c is clamped and exposed between the movable shielding portion 712c and the flat portion 53c of the peripheral side wall of the first liquid guiding element 50c, which is advantageous for production and assembly.

And a movable shielding portion 712c also serves to provide shielding or blocking between the exposed section 321c of the portion 32c and the inner wall surface of the main housing 10 after assembly to prevent the flexible exposed section 321c from extending into or being sandwiched between the inner wall surface of the main housing 10 and the bracket 70c during assembly.

Or in yet other variations, the air grooves 79a/79b/79c defining the air passages are defined or formed in the peripheral side wall of the first liquid guiding element 50a/50b/50 c.
