Referring to fig. 1 to 4, fig. 1 is a block diagram illustrating a vaporizing apparatus 1000 of smokable material according to an embodiment of the present utility model; FIG. 2 is a top view of the vaporizing device 1000 of smokable material shown in FIG. 1; FIG. 3 is a front view of the vaporizing device 1000 of smokable material shown in FIG. 1; fig. 4 is a bottom view of the vaporizing device 1000 of smokable material shown in fig. 1. As shown in fig. 1 to 4, the vaporizing device 1000 of the smokable material includes a fluid transport element 100 and a heating element 200; the fluid transfer element 100 has a liquid inlet surface 10 and an atomizing surface 20 arranged opposite to each other, and a microporous structure for transferring liquid smokable material to the atomizing surface 20 by capillary action, the fluid transfer element 100 having at least one side surface 30 adjacent to the atomizing surface 20, each side surface 30 being configured with at least one liquid guide slot 31, each liquid guide slot 31 extending vertically between the liquid inlet surface 10 and the atomizing surface 20; the heating element 200 is disposed on the atomizing surface 20, and is used for heating and atomizing the liquid smokable material to form aerosol for sucking.

Specifically, the vaporizing device 1000 of smokable material includes a fluid transfer element 100 and a heating element 200 disposed on an atomizing face 20 of the fluid transfer element 100. The fluid transfer element 100 includes a liquid inlet surface 10 and an atomizing surface 20 disposed opposite each other, for example, for a fluid transfer element 100 of rectangular configuration, the top surface of the rectangular configuration is the liquid inlet surface 10 and the bottom surface is the atomizing surface 20. Meanwhile, a microporous structure (not shown in the drawings) for transferring a liquid smokable material, which may be tobacco tar, is provided on the surface of the entire fluid transfer element 100.

At least one liquid guide groove 31 is formed on each side 30, each liquid guide groove 31 extending vertically between the liquid inlet surface 10 and the atomizing surface 20, the liquid guide groove 31 serving to accelerate the flow of liquid smokable material from the liquid inlet surface 10 to the atomizing surface 20. In use, liquid smokable material flows from the liquid inlet surface 10 to the microporous structure of the side surface 30 and from the microporous structure to the liquid guide groove 31, or alternatively, from the liquid inlet surface 10 directly to the liquid guide groove 31 at the side surface 30, and finally flows through the liquid guide groove 31 and the microporous structure to the atomizing surface 20, and the smokable material is heated by the heating element 200 at the atomizing surface 20 and atomized to form aerosol for inhalation. Due to the existence of the liquid guide groove 31, part of liquid smokable material flowing through the liquid guide groove 31 can be accelerated to enter the atomization surface 20, so that paste cores caused by insufficient liquid smokable material of the atomization surface 20 can be avoided, and the atomization effect is improved.

The reservoir 11 is primarily used to store liquid smokable material, reducing the time for the liquid smokable material to flow from the storage location to the liquid inlet level 10.

Alternatively, the liquid guiding groove 31 may be disposed on the inner wall of the liquid storage groove 11, may be disposed on the outer wall of the liquid storage groove 11, and may be disposed on both the inner wall and the outer wall of the liquid storage groove 11, which may be designed by those skilled in the art according to practical situations.
