  5. The tobacco roaster of any one of claims 1-2, wherein the high frequency heating module further comprises an upper thermal insulation gasket (5), a sleeve (11) and a lower thermal insulation gasket (12); the sleeve (11) is disposed in the magnetic induction coil (9) to prevent the deformation of the magnetic induction coil (9); the metal cup (7) is disposed in the sleeve (11); and the upper thermal insulation gasket (5) and the lower thermal insulation gasket (12) are disposed on two ends of the magnetic induction coil (9) respectively for thermal insulation.

Description

The invention relates to a tobacco roaster. Conventionally, a tobacco roaster comprises a fixedly disposed metal cup for accommodating a tobacco material. The tobacco material directly contacts the metal cup and is heated in the metal cup. Thus, the metal cup is easily stained and cannot be taken out of the tobacco roaster for cleaning. WO2019/178834A1 recites a tobacco roaster including a heating module, and a push rod that is disposed below the metal cup; in which the push rod is movable to push the metal cup out of the tobacco roaster. In addition, CN111406980A recites a cup for heating smoke material, in which the conductive metal is insulated from the smoke material. CN111165875A recites a smoke device, in which the conductive heater is disposed within a magnetic induction coil and used to generate an inductive current to heat the smoke material. The invention provides a tobacco roaster, comprising a high frequency heating module and a pushing assembly; the high frequency heating module comprises a metal cup and a magnetic induction coil; the metal cup is disposed in the magnetic induction coil; when an alternating current flows through the magnetic induction coil, an eddy current effect is formed in the metal cup and the metal cup is heated; the pushing assembly comprises a push rod disposed below the metal cup; the push rod is movable to push the metal cup out of the tobacco roaster. According to the invention, the pushing assembly further comprises a fixed rod; the push rod is disposed around the fixed rod and is movable up and down with respect to the fixed rod. In a class of this embodiment, the pushing assembly further comprises a press button; the push rod comprises a lateral beam; one end of the lateral beam extends out of the tobacco roaster; the press button is disposed on the one end of the lateral beam; the press button controls the push rod to move up and down. In a class of this embodiment, the high frequency heating module further comprises a glass cup disposed in the metal cup for accommodating a tobacco material. In a class of this embodiment, the high frequency heating module further comprises a glass cover disposed on an opening of the metal cup; and the glass cover comprises a top surface comprising a plurality of through holes for air circulation. In a class of this embodiment, the high frequency heating module further comprises an upper thermal insulation gasket, a sleeve and a lower thermal insulation gasket; the sleeve is disposed in the magnetic induction coil to prevent the deformation of the magnetic induction coil; the metal cup is disposed in the sleeve; and the upper thermal insulation gasket and the lower thermal insulation gasket are disposed on two ends of the magnetic induction coil respectively for thermal insulation. The following advantages are associated with the tobacco roaster of the disclosure: 1. The tobacco roaster comprises a pushing assembly which is movable to push the metal cup and glass cup out of the tobacco roaster for replacement and cleaning.2. The tobacco roaster comprises a glass cup disposed in the metal cup for accommodating the tobacco material. The tobacco material does not directly contact the metal cup. The design is environmentally friendly.3. The tobacco roaster comprises a glass cover comprising a plurality of through holes which can filter smoke and remove granulates, thus preventing the granulates from being inhaled. FIG. 1 is an exploded view of a tobacco roaster in accordance with one embodiment of the disclosure;FIG. 2 is a schematic diagram of a tobacco roaster in accordance with one embodiment of the disclosure; andFIG. 3 is a sectional view of a tobacco roaster in accordance with one embodiment of the disclosure. To further illustrate, embodiments detailing a tobacco roaster are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure. Principle of high frequency heating: when an alternating current is introduced to a magnetic induction coil, an alternating magnetic field will be generated.
