In this embodiment, by providing the first and second flow guide surfaces 50611 and 50621 as slopes on the mounting top cover 500, the air flow from the atomizing core 700 can be made to flow toward the converging air passage 508 along the first and second flow guide surfaces 50611 and 50621, and the first and second flow guide surfaces 50611 and 50621 guide the air flow from the atomizing core 700 to the converging air passage 508 along a shorter path. The area enclosed by the dotted line in fig. 10 is an area where aerosol is likely to remain in the mounting top cap 500, and through the arrangement of the first flow guide surface 50611 and the second flow guide surface 50621, the flow of the air flow in the first flow guide air passage and the second flow guide air passage is smoother, so that the residue of the aerosol in the cavities of the first flow guide air passage and the second flow guide air passage is greatly reduced, and the output of the aerosol in the atomizer 100 is facilitated.
In this embodiment, the first flow guiding surface 50611 and the second flow guiding surface 50621 form an "inverted V" shape, and an intersection line between the first flow guiding surface 50611 and the second flow guiding surface 50621 and any one of the two sidewalls of the first flow guiding groove 5061 and the second flow guiding groove 5062 is also an "inverted V" shape, so that most of the condensed liquid can be guided by the first flow guiding surface 50611 and the second flow guiding surface 50621 and flows from the collecting air duct 508 to the sidewall of the atomizing core 700. In one embodiment, the first flow guiding surface 50611 and the second flow guiding surface 50621 are both planar, and the first flow guiding surface 50611 and the second flow guiding surface 50621 are configured to be planar to facilitate the flow of condensate along the first flow guiding surface 50611 and the second flow guiding surface 50621. In other embodiments, the first flow-guiding surface 50611 and the second flow-guiding surface 50621 may also be curved surfaces.
The intersection line of the bottom surface (i.e., the first flow guide surface 50611) and the side surface of the first flow guide groove 5061 forms an included angle of 30-70 degrees with the central axis O of the mounting top cover 500; similarly, the intersection line of the bottom surface (i.e., the second flow guide surface 50621) and the side surface of the second flow guide groove 5062 forms an angle of 30-70 degrees with the central axis O of the mounting top cover 500. Fig. 10 illustrates an included angle α between the second flow guiding surface 50621 and the central axis O, and the included angle α is set to adjust the slopes of the first flow guiding surface 50611 and the second flow guiding surface 50621 relative to the radial direction, so that the slopes of the first flow guiding surface 50611 and the second flow guiding surface 50621 are not too large or too small. When the slopes of the first and second flow guide surfaces 50611 and 50621 are too large or too small, the air flow is difficult to flow from the second and third openings to the air outlet passage 508 along a short path, and the air flow is easily collected inside the first and second flow guide grooves 5061 and 5062. The path of the air flow with the included angle between 30 degrees and 70 degrees is short, and the air flow can circulate more smoothly in the first flow guide groove 5061 and the second flow guide groove 5062. In other embodiments, the included angle may be other angles, and may be designed to have a reasonable value according to the internal configuration of the atomizer 100.
Referring to fig. 5 to 8, in the present embodiment, a third flow guiding surface 510 is further disposed at the intersection of the first flow guiding air passage and the second flow guiding air passage, two ends of the third flow guiding surface 510 are respectively connected to the first flow guiding surface 50611 and the second flow guiding surface 50621, and the third flow guiding surface 510 faces the converging air passage 508 and is spaced from the converging air passage 508. The first flow guiding surface 50611 and the second flow guiding surface 50621 are directly connected only near two ends of the same side wall of the first flow guiding groove 5061 and the second flow guiding groove 5062, and two ends of the third flow guiding surface 510 near the side walls of the first flow guiding groove 5061 and the second flow guiding groove 5062 extend to the direct connection position of the first flow guiding surface 50611 and the second flow guiding surface 50621. The width of the third guide surface 510 near the central axis O of the mounting top cover 500 is greater than the width of the third guide surface 510 near the sidewalls of the first and second guide grooves 5061 and 5062, and the width of the third guide surface 510 at the connection with the sidewalls of the first and second guide grooves 5061 and 5062 may be zero, i.e., a tip is formed. In one embodiment, the first flow guide surface 50611, the second flow guide surface 50621, and the third flow guide surface 510 have a common intersection point, and the common focus is located at a junction of a sidewall of the first flow guide channel 5061 and a sidewall of the second flow guide channel 5062. The third flow guiding surface 510 may be concave, that is, both sides of the third flow guiding surface 510 close to the side wall of the first flow guiding groove 5061 and the side wall of the second flow guiding groove 5062 are higher than the height of the third flow guiding surface 510 close to the central axis O, that is, both sides of the third flow guiding surface 510 close to the side wall of the first flow guiding groove 5061 and the side wall of the second flow guiding groove 5062 are closer to the converging air passage 508 than the middle of the third flow guiding surface 510 close to the central axis O.
Further, the third guiding surface 510 is also provided with a first guiding groove 509. The first liquid guiding groove 509 is disposed at the lowest position of the concave surface of the third flow guiding surface 510. The first liquid guiding groove 509 of the third flow guiding surface 510 extends along the thickness direction of the mounting top cover 500, and both ends of the first liquid guiding groove extend to the first flow guiding surface 50611 and the second flow guiding surface 50621 respectively.
The third flow guiding surface 510 is a concave surface, and the first liquid guiding groove 509 is disposed at the lowest position of the concave surface, so that a part of the condensate flowing to the third flow guiding surface 501 can be gathered in the first liquid guiding groove 509 of the third flow guiding surface 510 along the third flow guiding surface 510, and further guided to the first liquid guiding groove 509 of the first flow guiding surface 50611 and the second flow guiding surface 50621 by the first liquid guiding groove 509 of the third flow guiding surface 510. Therefore, most of the condensate can flow into the first liquid guiding groove 509 of the first flow guiding surface 50611, the second flow guiding surface 50621 and the third flow guiding surface 510, and the effect of converging and guiding the condensate in the first liquid guiding groove 509 can be effectively realized, so that the condensate can be guided more smoothly.
The first guiding grooves 509 disposed on the first guiding surface 50611, the second guiding surface 50621, and the third guiding surface 510 may be connected to each other or disconnected from each other. In this embodiment, the number of the first liquid guiding grooves 509 is three, and the three first liquid guiding grooves 509 are respectively disposed on the first flow guiding surface 50611, the second flow guiding surface 50621 and the third flow guiding surface 510, and are communicated with each other.
In this embodiment, the first liquid guiding groove 509 of the first flow guiding surface 50611 extends from one end of the first liquid guiding groove 509 of the third flow guiding surface 510 to one end of the first flow guiding surface 50611 far away from the converging air channel 508; the first liquid guiding groove 509 of the second flow guiding surface 50621 extends from one end of the first liquid guiding groove 509 of the third flow guiding surface 510 to one end of the second flow guiding surface 50621 away from the converging air passage 508. Specifically, the first liquid guiding groove 509 of the first flow guiding surface 50611 extends from one end of the first liquid guiding groove 509 of the third flow guiding surface 510 to a position where one end of the first flow guiding surface 50611 far away from the converging air passage 508 intersects with a side surface of the first flow guiding groove 5061; the first liquid guiding groove 509 of the second flow guiding surface 50621 extends from one end of the first liquid guiding groove 509 of the third flow guiding surface 510 to a position where one end of the second flow guiding surface 50621 far from the converging air passage 508 intersects with a side surface of the second flow guiding groove 5062. The condensate in the first diversion trench 509 on the first diversion surface 50611 and the second diversion surface 50621 is finally diverted to the positions of the first diversion surface 50611 and the second diversion surface 50621 close to the side wall of the atomizing core 700, so that the reflux and drainage of the condensate by the first diversion trench 509 are realized, and the risk of suction and leakage of a user is reduced.

One end of each of two or more sub-guiding grooves on the first guiding surface 50611 is communicated with one end of the first guiding groove 509 of the third guiding surface 510, and the other end of each of the two or more sub-guiding grooves extends to a position where one end of the first guiding surface 50611 far away from the converging air passage 508 intersects with two side surfaces of the first guiding groove 5061; one end of each of the two sub-fluid guiding grooves on the second fluid guiding surface 50621 is communicated with one end of the first fluid guiding groove 509 of the third fluid guiding surface 510, and the other end of each of the two sub-fluid guiding grooves extends to a position where one end of the second fluid guiding surface 50621, which is far away from the converging air passage 508, intersects with the side surface of the second fluid guiding groove 5062. The sub liquid guide groove divides the condensate on the first flow guide surface 50611 and the second flow guide surface 50621, so that the flowing speed of the condensate is higher, and the risk of liquid leakage suction of a user is further reduced. In this embodiment, the number of the sub liquid guiding grooves is four, and in other embodiments, the number of the sub liquid guiding grooves can be set to other numbers according to needs.
The mounting top cover 500 further comprises a liquid guide part 511, one end of the liquid guide part 511 is arranged on one side of the top wall 501 close to the atomizing core 700 and is connected with the first liquid guide groove 509 on the first flow guide surface 50611 and/or the second flow guide surface 50621; the other end of the liquid guide portion 511 extends to the side wall of the atomizing core 700 and contacts the side wall of the atomizing core 700.

In this embodiment, the number of the liquid guiding portions 511 is four, and the four liquid guiding portions are respectively connected to the four sub-liquid guiding grooves, so that the condensate is divided from the first liquid guiding groove 509 of the third flow guiding surface 510 to flow to the four sub-liquid guiding grooves of the first flow guiding surface 50611 and the second flow guiding surface 50621, and finally guided to the side wall of the atomizing core 700 along the liquid guiding portions 511, thereby realizing the reutilization of the condensate. In other embodiments, the number of the liquid guiding portions 511 may be one or more, and may be set according to the number of the sub liquid guiding grooves.
Further, the surface of the liquid guiding part 511 close to the atomizing core 700 is provided with a second liquid guiding groove 512, one end of the second liquid guiding groove 512 is communicated with the first liquid guiding groove 509, and the other end extends to one end of the liquid guiding part 511 far away from the converging air passage.
