That is, the suction device 1 mainly depends on the mechanical vibration of the vibrating member 120, so that the liquid entering the atomizing chamber 12 is vibrated and passes through the screen 121 (as shown by the vertical solid line arrow in fig. 1) along the vibration direction (as shown by the X direction in fig. 1) to form the aerosol (as shown by the vertical dotted line arrow in fig. 1). Specifically, be equipped with first through-hole 142 between liquid storage cavity 10 and the atomizing chamber 12, liquid in the liquid storage cavity 10 can get into atomizing chamber 12 through first through-hole 142 (as shown by the solid arrow in the horizontal line in fig. 1), and vibrating member 120 is surrounded by the liquid in the atomizing chamber 12, and the part is soaked in liquid, but vibrating member 120 is whole incompletely by liquid submergence to make vibrating member 120 can effectually vibrate liquid, and liquid is got up by vibrating member 120 vibration back, can pass screen cloth 121, forms aerial fog.

As used herein, a "liquid" may be a tobacco tar or a tobacco liquid, which refers to a liquid comprising one or more of glycerin and propylene glycol, which may or may not further comprise one or more of nicotine or a nicotine salt.

By adopting the technical scheme, the liquid can be atomized in the environment of not more than 100 ℃ by utilizing the mechanical energy of the screen and the vibrating piece, the complex chemical reaction can not be generated, the generation of harmful substances is avoided, and better use experience is provided for users.

It should be noted that, the specific structures of the vibrating member and the screen mesh are not limited in the present invention, and may be appropriately selected and designed according to actual needs, as long as the liquid can be effectively atomized.

In order to enable the liquid passing through the mesh 121 to be sufficiently atomized, in the present embodiment, the mesh diameter of the mesh 121 is in the range of 0.3 μm to 10 μm, and preferably, the mesh diameter of the mesh 121 is in the range of 1 μm to 3 μm. As used herein, "mesh diameter" refers to the minimum pore diameter for a non-uniform axial cross-section of the mesh, e.g., the diameter of the pore at the tip is defined as the diameter of the mesh. In other embodiments, the mesh diameter of the screen may have other values, and the invention is not limited in this regard as long as it is ensured that the liquid passing through the screen can be atomized.

Meanwhile, referring to fig. 1, in the present embodiment, the vibrating member 120 has a cylindrical structure, the diameter of the upper protruding portion of the vibrating member 120 is smaller than that of the main body, and the piezoelectric element is integrally encapsulated in the main body, and can vibrate when energized. In this embodiment, the vibration frequency range of the vibrating element 120 is 80KHz to 2.5MHz, preferably, the vibration frequency range of the vibrating element 120 is 180KHz to 200KHz, the vibration frequency of the vibrating element 120 can be adjusted as required, different power gears can be adjusted by key operation to adapt to liquids with different viscosities, and different amounts of smoke can be generated by adjusting different power gears.
