Heating device comprising heating element and high-frequency heating assembly

Abstract

A heating device includes a heating element and a high-frequency heating assembly. In a power-on state, the heating element and the high-frequency heating assembly operate to generate heat and heat tobacco materials in the heating device to produce smoke or vapor.

What is claimed is: 
     
         1 . A heating device, comprising a heating element and a high-frequency heating assembly; wherein in a power-on state, the heating element and the high-frequency heating assembly operate to generate heat and heat tobacco materials in the heating device to produce smoke or vapor. 
     
     
         2 . The heating device of  claim 1 , wherein the high-frequency heating assembly comprises an induction coil and a container for holding the tobacco materials, and the container is disposed in the induction coil. 
     
     
         3 . The heating device of  claim 2 , wherein the high-frequency heating assembly further comprises a variable-frequency power supply; an output terminal of the variable-frequency power supply is connected to an input terminal of the induction coil; when the variable-frequency power supply is energized, an alternating current is produced and passes through the induction coil, whereby an alternating magnetic field is produced; and the container in the alternating filed is heated and transfers the heat to the tobacco materials. 
     
     
         4 . The heating device of  claim 1 , wherein the heating element is disposed on the container so that the tobacco materials are covered in the container. 
     
     
         5 . The heating device of  claim 1 , wherein the heating element comprises a main body provided with a plurality of through holes. 
     
     
         6 . The heating device of  claim 5 , wherein the heating element further comprises a plurality of heating wires disposed in the plurality of through holes, respectively. 
     
     
         7 . The heating device of  claim 6 , wherein the heating device further comprises a power supply board for supplying power to the heating element; the plurality of heating wires each comprises a lead wire connected to the power supply board; and the power supply board is electrically connected to the variable-frequency power supply. 
     
     
         8 . The heating device of  claim 7 , wherein the heating device further comprises a temperature probe; the temperature probe comprises a lead wire connected to the power supply board and a body disposed in the container. 
     
     
         9 . The heating device of  claim 2 , wherein the container comprises a metal, or a non-metal comprising an embedded metal; and the container is circular, square, quadrilateral, or polygonal in shape. 
     
     
         10 . The heating device of  claim 6 , wherein the heating element is circular, and the plurality of heating wires is disposed on the heating element. 
     
     
         11 . The heating device of  claim 1 , wherein the heating device further comprises a socket. 
     
     
         12 . The heating device of  claim 6 , wherein the heating device further comprises a top panel. 
     
     
         13 . A hookah, comprising the heating device of  claim 1  and a smoke filter connected to the heating device; when in use, the smoke produced by the heating device passes through the smoke filter and is inhaled by a smoker. 
     
     
         14 . The heating device of  claim 13 , wherein the smoke filter comprises a water container, a smoke guide pipe, and an exhaust pipe; the smoke guide pipe comprises a first end connected to the heating device and a second end disposed below a liquid level of the water container; the exhaust pipe comprises a first end part communicating with a mouthpiece, and a second end part disposed above liquid level of the water container; when in use, the smoke flows through the smoke guide pipe, is filtered by water, flows out of the exhaust pipe, and enters into the mouthpiece.
