Further in accordance with the preferred embodiment shown in fig. 3 and 4, in order to stably retain and assemble the atomizing assembly 30; the main casing 10 is provided therein with:
a silicone sleeve 50 for accommodating and wrapping the liquid guiding member 310;

On the stable holding of the liquid guiding element 310, the silicone sleeve 50 has a first accommodating space 51, and the liquid guiding element 310 is accommodated and held in the first accommodating space 51; the rigid support 60 has a second accommodation space 61, and the silicone sleeve 50 and the liquid guiding member 310 are integrally fitted in the second accommodation space 61.
With further reference to fig. 3 to 5, in the structural design of the liquid flow channel formed in a matching manner, the sealing element 80 is provided with a first liquid guiding hole 81, the rigid support 60 is provided with a second liquid guiding hole 62, and the silica gel sleeve 50 is provided with a third liquid guiding hole 52; in use, the liquid medium in reservoir chamber 12 flows through first drainage hole 81, second drainage hole 62 and third drainage hole 52 in sequence, and then flows onto drainage element 310 to be absorbed, as shown by arrow R1 in fig. 4 and 5; and finally, the atomized liquid is released into the atomization chamber after being atomized on the atomization surface of the liquid guide element 310.
With further reference to fig. 3, in the configuration of forming the suction airflow, the atomization chamber defined by the silicone receiving element 42 and the liquid guiding element 310 is communicated with the air inlet 22 provided on the end cap 20. Meanwhile, the sealing element 80 is provided with a first inserting hole 82 for inserting the flue gas output pipe 11; the rigid bracket 60 is provided with a second insertion hole 66 opposed to the first insertion hole 82, and an output passage 63 on one side in the thickness direction. After the external air enters the atomizing chamber from the air inlet hole 22 on the end cap 20, the generated aerosol is output from the output channel 63 to the smoke output tube 11 connected to the second insertion hole 66 until the aerosol is sucked through the air suction opening a, as shown by the arrow R2 in fig. 3.
With further reference to fig. 4 and 6, in order to replenish the reservoir 12 with air to minimize the negative pressure within the reservoir 12, the rigid support 60 is provided with a first air passage 64 and a second air passage 65; in use, both the first air passage 64 and the second air passage 65 are used to replenish air within the reservoir chamber 12. Wherein the content of the first and second substances,
a first air passage 64 extends through the rigid carrier 60 in the longitudinal direction;
the second air passage 65 is formed by a space such as a groove/opening on the outer side wall in the width direction of the rigid bracket 60.
In other alternative implementations, the first air passage 64 and the second air passage 65 may not be present at the same time, and only one of them may be implemented.
In cooperation with the above structure, the sealing member 80 is provided with a shielding portion 83 for covering and sealing the air outlet end of the first air passage 64. According to fig. 6, the shielding portion 83 is formed by being surrounded by a U-shaped groove or slit 831, and the shielding portion 83 is suspended from the other portion of the sealing member 80. In a normal case, the shielding portion 83 covers the air outlet end of the first air passage 64; when the negative pressure in the reservoir 12 increases beyond the threshold, the shielding portion 83 can bend or tilt in the reservoir 12 in response to the change in the negative pressure as shown in fig. 7, and further open the air outlet end of the first air passage 64, so that the external air enters the reservoir 12 to relieve the negative pressure.
With further reference to the embodiment shown in fig. 6, the shielding portion 83 of the sealing member 80 is configured to extend in the width direction; of course, in a variable implementation, there may be some oblique angle to the width direction. The angle of the preferable implementation included angle can be between-90 degrees and 90 degrees.
With further reference to the implementation shown in fig. 6, the sealing element 80 is shaped to have an end wall 810, and a sidewall 820 extending from the end wall 810 and covering the carrier 60. The above shielding portion 83 is formed on the end wall 810. The sealing element 80 simultaneously has an edge position 85 closest to the front end free end 831 of the shielding portion 83. In the sealing member 80 of the shape and size of fig. 6, the edge position 85 is a position where the edge position in the width direction is near the free end 831; the distance d1 between the edge position 85 and the free end is 4.2 mm. The distance d2 between the shielding portion 83 and the side edge of the sealing member 80 in the thickness direction of the atomizer 100 was 4.8 mm. The connecting end 834 of the shielding portion 83, which is away from the free end 831, is relatively far away from the edge position 85, so that during the assembling process, the edge position is subjected to friction or deformation tension and the like during the assembling process and is not transmitted to the connecting end 834 of the shielding portion 83, and is separated by the slit defining the free end 831, thereby keeping the connecting end 834 from being deformed to open the first air passage 64.
As further shown in fig. 6, the shielding portion 83 has a free end 832, the free end 832 being defined by a U-shaped slot or slit 831; the free end 832 is formed to be deformable, such as to bend or tilt, relative to the sealing member 80. Meanwhile, the U-shaped groove or slit 831 forming the shielding portion 83 is formed to extend in the width direction of the sealing member 80, and the shielding portion 83 also extends in the width direction of the sealing member 80. And, the bending direction of the U-shaped groove or slit 831 is toward the center of the sealing member 80; when the sealing member 80 is fitted into the main casing 10 upward from the open end of the main casing 10 during the fitting process, the shielding portion 83, which is substantially isolated from the width edge of the sealing member 80, does not bend or tilt as the edge portion is rubbed by the inner wall of the main casing 10 when the width edge of the sealing member 80 rubs against the inner wall of the main casing 10; the shield portion 83 remains substantially flush or sealed against the port of the first air passage 64 after assembly.
The sealing member 80 is provided with a through hole 84 opposite to the air outlet end of the second air channel 65, and the air in the second air channel 65 enters the liquid storage chamber 12 through the through hole 84. To prevent the liquid medium in the reservoir chamber 12 from flowing out of the through-hole 84 directly into the second air passage 65 in a large amount, first, the inside of the second air passage 65 near the air outlet end is filled with the porous material 70. In practice, the porous material 70 is preferably flexible, and may be a sponge, a fiber cotton, a porous foam, or the like; the exuded liquid matrix may be locked when filled in the second air passage 65.
And in the preferred embodiment shown in fig. 6, the inner diameter of the air outlet end of the second air passage 65 is larger than that of the first air passage 64;
the inner diameter of the through hole 84 is about 3 to 5mm, which is smaller than the inner diameter of the second air passage 65, and prevents the liquid medium from largely seeping out to the second air passage 65. Meanwhile, in the preferred embodiment shown in fig. 6, the second air passage 65 is a groove formed in a side wall of the rigid bracket 60 in a portion thereof near the widthwise edge of the rigid bracket 60.
Referring to fig. 6, the outer walls of both sides of the rigid bracket 60 have recessed structures 67 at least partially surrounding the rigid bracket 60 in the circumferential direction, and the second air passage 65 communicates with the outside air by communicating with the recessed structures 67. Further, a plurality of capillary grooves 68 are formed in the outer wall of the rigid support 60 and are in air flow communication with the atomization chamber and the recessed structure 67, so that external air can enter the recessed structure 67 through the capillary grooves 68. At the same time, the capillary groove 68 is also capable of wicking and retaining aerosol condensate generated within the aerosolizing chamber.
In a more preferred embodiment, the air inlet ends of the first air passage 64 and the second air passage 65 are directly communicated with the external atmosphere through the rigid support 60 or the through hole on the wall of the main housing 10, and the other air inlet ends are the same as the atmospheric pressure, so that the external air directly enters the reservoir chamber 12 when the negative pressure in the reservoir chamber 12 is too high.
As further shown in fig. 7, the inner diameter of the first air passage 64 is varied, for example, gradually or stepwise; preferably with a decreasing inner diameter in a direction closer to the reservoir 12. For example, in fig. 7, the first air channel 64 includes a first portion 641, a second portion 642 and a third portion 643 with different inner diameter sizes sequentially along the direction approaching the reservoir 12; the inner diameters of the first, second and third portions 641, 642, 643 are tapered.
As shown in fig. 6, the upper surface of the rigid bracket 60 is further provided with a ledge 641 surrounding the port of the first air passage 64, and the shielding portion 83 abuts and abuts against the ledge 641 after assembly.
Further fig. 8 and 9 show a schematic structural view of a further embodiment of a sealing element 80a sealing the first air passage 60a of the rigid carrier 60 a; wherein the content of the first and second substances,
the inner diameter of the third portion 643a of the first air passage 60a is conically decreasing in shape and has a notch at the air outlet end; the shielding portion 83 of the corresponding sealing element 80a has a protrusion 832a capable of extending into the recess, so that the vent end of the third portion 643a is sealed by the protrusion 832 a.
While further facilitating the bending deformation of the shielding portion 83, it is advantageous to provide the recessed structures 833a on the surface of the shielding portion 83a facing the rigid bracket 60a to reduce the thickness and strength of the shielding portion 83 so that it can more sensitively respond to the change in negative pressure to generate the deformation of bending or tilting.
It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
