Thus, the atomized liquid can be guaranteed to better conduct oil to the bottom and the part of the oil guiding body 1 where the heating body 2 is located.

It should be understood that the larger the number of the flow guide grooves 111, the smaller the size of the flow guide grooves 111 in the extending direction of the atomizing tank 10. For example: when the oil guide body 1 is provided with one guide groove 111, the size of the guide groove 111 is 0.6-0.7 times of the size of the oil guide body 1 in the extending direction of the atomizing groove 10; when the oil guide body 1 is provided with two guide grooves 111, the size of the guide grooves 111 is 0.4-0.6 times of the size of the oil guide body 1 in the extending direction of the atomizing groove 10; when the oil guide body 1 is provided with three guide grooves 111, the size of the guide grooves 111 is 0.3 to 0.4 times the size of the oil guide body 1 in the extending direction of the atomizing tank 10.

Specifically, the first direction is perpendicular to the second direction, and because the thicknesses of the two side walls 12 in the second direction are equal, in this embodiment, the first direction and the second direction are both oil inlet directions, and because the thicknesses of the two side walls 12 in the second direction are equal, the oil inlet amounts of the two side walls 12 of the oil guide body 1 in the first direction are more uniform. In some embodiments, the thickness of the two sidewalls 12 in the second direction may also be unequal. In some embodiments, the thickness of the sidewall 12 in the second direction may also be greater than or equal to the thickness of the body 11 in the first direction, which may allow for a larger volume of the nebulization chamber, thereby increasing the aerosol containment.

Further, the atomizing groove 10 penetrates through two ends of the oil guiding body 1, and the cross section of the atomizing groove 10 is one of C-shaped, U-shaped and folded line-shaped.

In some embodiments, the cross-section of the nebulization channel 10 can also be C-shaped, U-shaped, etc.

In some embodiments, the cross section of the atomizing tank 10 may be different throughout the length direction, for example, in the case of the same cross section shape, the cross section of the atomizing tank 10 near the middle is smaller than the cross section near the ends, so that the airflow has a larger flow velocity at the middle of the atomizing chamber, and the aerosol formed in the middle of the heating body 2 can be driven to flow away quickly, thereby improving the aerosol generation rate. It should be understood that the cross-sectional shape and size of the atomizing tank 10 in the longitudinal direction can be adaptively adjusted according to actual needs, and is not limited herein.
