Cut tobacco heating device

Abstract

A cut tobacco heating device includes a tobacco mouthpiece; a tobacco rod including a heating cup disposed therein for holding cut tobacco; at least one sliding part disposed on the tobacco mouthpiece or the tobacco rod; and at least one connecting part, the tobacco mouthpiece and the tobacco rod being in rotatable connection through the at least one connecting part. By providing a connecting part and a sliding part between the tobacco rod and the tobacco mouthpiece, when in use, the sliding part and the connecting part are used to slide and rotate the tobacco mouthpiece to open the cut tobacco heating device. The cut tobacco can directly be put into the heating cup, then the tobacco mouthpiece is returned to its original position, and the cut tobacco in the cut tobacco heating device is heated to produce the smokes for being inhaled, which is convenient for operation.

What is claimed is:

         2 . The cut tobacco heating device of  claim 1 , further comprising an upper housing, the upper housing being provided with a tobacco cavity, and the tobacco mouthpiece being detachably disposed on the upper housing and communicated with the tobacco cavity. 
     
     
         3 . The cut tobacco heating device of  claim 1 , further comprising at least one first limiting member for limiting a position of the rotating shaft, the at least one first limiting member being disposed on an inner wall of the sliding groove and located at an upper end of the sliding groove. 
     
     
         4 . The cut tobacco heating device of  claim 2 , further comprising at least one first limiting member for limiting a position of the rotating shaft, the at least one first limiting member being disposed on an inner wall of the sliding groove and located at an upper end of the sliding groove. 
     
     
         5 . The cut tobacco heating device of  claim 3 , wherein a shape of the at least one first limiting member is semi-circular, the at least one first limiting member is provided with two in total, and the two first limiting members are symmetrically disposed on both sides of the sliding groove. 
     
     
         6 . The cut tobacco heating device of  claim 3 , further comprising at least one second limiting member for limiting a position of the rotating shaft, the at least one second limiting member being disposed on the inner wall of the sliding groove and located at a lower end of the sliding groove. 
     
     
         7 . The cut tobacco heating device of  claim 6 , wherein a shape of the at least one second limiting member is semi-circular, the at least one second limiting member is provided with two in total, and the two second limiting members are symmetrically disposed on both sides of the sliding groove. 
     
     
         8 . The cut tobacco heating device of  claim 4 , wherein a shape of the at least one first limiting member is semi-circular, the at least one first limiting member is provided with two in total, and the two first limiting members are symmetrically disposed on both sides of the sliding groove. 
     
     
         9 . The cut tobacco heating device of  claim 4 , further comprising at least one second limiting member for limiting a position of the rotating shaft, the at least one second limiting member being disposed on the inner wall of the sliding groove and located at a lower end of the sliding groove. 
     
     
         10 . The cut tobacco heating device of  claim 9 , wherein a shape of the at least one second limiting member is semi-circular, the at least one second limiting member is provided with two in total, and the two second limiting members are symmetrically disposed on both sides of the sliding groove. 
     
     
         11 . The cut tobacco heating device of  claim 2 , further comprising a tobacco pipe, the tobacco pipe being disposed in the tobacco cavity, one end of the tobacco pipe being communicated with the tobacco mouthpiece, and another end of the tobacco pipe being communicated with the material feeding and discharging opening of the heating cup. 
     
     
         12 . The cut tobacco heating device of  claim 11 , further comprising a blocking screen for blocking the cut tobacco or tobacco ash, and the blocking screen being mounted on the tobacco pipe and located at an end of the tobacco pipe which is away from the tobacco mouthpiece.
