Likewise, the outer surface of the flexible sealing member 70 also has a second rib 74 surrounding the flexible sealing member 70 for being tightly clamped by the inner wall of the main housing 10 and the bracket 60 by the inner and outer sides against the second rib 74 after assembly, forming an area of interference fit to effectively seal the reservoir 12. Of course, the third path portion 321 defined by the second avoiding groove 73 avoids the interference area formed by the second rib 74.
In a preferred embodiment, the air inlet port of the first air hole 65 and/or the second air hole 66 are in air flow communication with the nebulizing chamber 340 through the gap between the support frame 60 and the main housing 10, so that in use, air from the nebulizing chamber 340 enters the reservoir 12 through the first air hole 65 and/or the second air hole 66. In other variations, the inlet port of the first and/or second air holes 65, 66 may be in direct communication with the outside atmosphere.
Further in a more preferred implementation, referring to fig. 9 and 10 in combination with fig. 6, the porous body 30 is shaped in an arcuate shape and has first and second side walls 31 and 32 opposed in the thickness direction and a base portion 34 extending between the first and second side walls 31 and 32; the lower surface of the base portion 34 is configured as a fogging surface 310. And the first side wall 31 and the second side wall 32 are extended along the length direction of the porous body 30, thereby defining a liquid channel 33 extended along the length direction of the porous body 30 between the first side wall 31 and the second side wall 32, and guiding and receiving the liquid substrate flowing down from the first liquid guiding hole 71, the second liquid guiding hole 61 and the third liquid guiding hole 51 through the liquid channel 33.
As further shown in fig. 9, the first air holes 65 are configured to extend in the width direction of the atomizer 100, and are opposed to the liquid passage 33 of the porous body 30 in the width direction. Meanwhile, the first avoiding groove 52 formed in the side wall of the flexible sealing boot 50 is formed in the outer surface of the side wall of the porous body 30 corresponding to the liquid passage 33 in the longitudinal direction thereof.
In other variant implementations, the above first avoidance groove 52 and/or the second avoidance groove 73 may also be formed on the bracket 60. For example, FIG. 11 shows a schematic view of a bracket 60a of yet another embodiment; the surface of the bracket 60a surrounded by the flexible sealing member 70 has a second avoiding groove 67a extending in the longitudinal direction, which provides the third path portion 321 shown in fig. 11 on the one hand, and keeps the air inlet port of the second air hole 66a from being closely adhered or sealed by the sealing member 70 on the other hand, so as to keep air smoothly entering the second air hole 66 a.
Likewise, the first avoidance groove 52 may be formed on the inner surface of the holding space 64 of the bracket 60 to form the second path portion R312 of the first air passage with the outer surface of the flexible sealing boot 50.
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.
