Meanwhile, the air inlet group 2 is provided with an adjusting component 3 for adjusting the oil smoke pumping rate, and the oil smoke flow is automatically controlled by changing the size of the area of the air inlet group 2 into which the oil smoke can be introduced.
The shell 11 of cigarette machine main part 1 is spherical, and adjusting part 3 includes spherical cover 31, and spherical cover 31 rotates and assembles in cigarette machine main part 1 outside, and a plurality of regulation holes 32 have been seted up to spherical cover 31, and flux is the biggest when adjusting hole 32 and air intake group 2 totally match, and flux is minimum until can close air intake group 2 when adjusting hole 32 and air intake group 2 totally do not match.
In this embodiment, the outer shell 11 of the cigarette maker body 1 is designed to be spherical in shape in order to facilitate the assembly and use of the spherical cap 31.
When the device is static, the adjusting holes 32 correspond to the air inlet groups 2 one by one, and after the device is started, the area of an oil smoke inlet surface communicated with the adjusting holes 31 and the air inlet groups 32 is gradually reduced due to the fact that the adjusting holes rotate along with the spherical cover 31, and therefore the purpose of reducing oil smoke flux is achieved.
Specifically, when the adjusting hole 32 of the spherical cap 31 is completely aligned with the air inlet set 2, the oil smoke circulation at the air inlet set 2 is maximum.
After the spherical cover 31 is rotated, the spherical cover 31 partially covers the air inlet set 2, so that the oil smoke circulation of the air inlet set 2 is reduced, and the purpose of adjusting the oil smoke circulation at the air inlet set 2 is achieved.
In order to assemble the spherical cover 31 without affecting the overall aesthetic appearance, the cigarette maker body 1 is assembled with the motor 33, and the rotor of the motor 33 is rotatably connected to the central portion of the inner surface of the spherical cover 31.

According to the principle of aerodynamics, the housing 11 is designed to be of an uncovered area structure, and in the process of absorbing oil smoke, the oil smoke flows along the surface of the housing 11 and is finally sucked by the air inlet group 2.
The embodiment is a structure with multiple air inlet sets 2, the multiple air inlet sets 2 absorb oil smoke, a rolling absorption effect is formed on the surface of the shell 11, and the oil smoke absorption capacity is enhanced.
According to different oil fume adsorption capacities of the air inlet group 2, the air inlet group 2 comprises an upper air inlet group 22 and a lower air inlet group 22.
The air inlet group 2 positioned at the middle upper part absorbs less oil smoke to be used as the clean air inlet group 2, and the air inlet group 2 positioned at the middle lower part absorbs more oil smoke.
Specifically, the opening of the upper intake port group 21 is directed directly or obliquely upward. The opening of the lower air inlet set 22 faces to the right lower direction, the oblique lower direction or the horizontal direction.
The middle lower part of the shell 11 is a lampblack contact area, and the lower air inlet group 22 is assembled in the lampblack contact area.

When the two shifting sheets 34 are completely closed, the air inlet set 2 is in a closed state, and no oil smoke is sucked.
When the shifting pieces 34 are gradually opened, the gaps between the shifting pieces 34 are gradually reduced and increased, the smoke passing area is also gradually reduced, the oil smoke adsorption quantity is gradually increased, and otherwise, the operation is performed even if the smoke passing adsorption quantity is reduced.
When the two shifting pieces 34 are completely opened, the smoke passing area of the air inlet group 2 is the largest, the smoke passing area is the same as the maximum adsorption area of the air inlet group 2, and the oil smoke adsorption capacity is the largest.
In order to ensure that the poking pieces 34 can realize the complete opening and closing of the smoke ventilation at the air inlet group 2, the total surface area of the spliced two poking pieces 34 is not less than the surface area of the section of the air inlet group 2.
