Abstract

A press puffing device includes a piston support, a nozzle holder, and a sealing fixer. In the press puffing device, a power supply start button is pressed to produce an aroma gas, and the aroma gas is contained in the cylindrical inner cavity. By pressing the piston support, the contained smoke is compressed and flows to the air outlet through the lateral gas channel to spurt out.

First claim

What is claimed is:

1. A press puffing device, comprising:
a piston support, comprising a left cylindrical cavity, a right cylindrical cavity, and a connection portion between the left cylindrical cavity and the right cylindrical cavity, wherein an upper end and a lower end of the left cylindrical cavity and an upper end and a lower end of the right cylindrical cavity are open;
a nozzle holder, comprising a cylindrical inner cavity with a roof, wherein a lateral gas channel is provided on a side wall of the cylindrical inner cavity; the lateral gas channel is connected to an air outlet for air to pass through; and a nozzle holder guide slot penetrating the side wall of the cylindrical inner cavity is provided on the side wall of the cylindrical inner cavity;
a sealing fixer, comprising a left cavity, a right cavity and a partition wall between the left cavity and the right cavity, wherein a sealing fixer sliding slot is provided on the partition wall; and an inner shape of the left cavity is matched with an outer shape of the nozzle holder; and
a roasting-type heating device, comprising a cigarette heating tube, a heating element, and a thermal insulation pipe, wherein the heating element is disposed on an outer side of the cigarette heating tube; the thermal insulation pipe is sleeved on an outer side of the heating element; a porous thermal insulation material is disposed between the heating element and the thermal insulation pipe; and a shape of the porous thermal insulation material is cylindrical; and wherein a solid tobacco material is heated by roasting and subjected to a pyrolysis to produce an aroma material, and the solid tobacco material is formulated and processed into a cylindrical cigarette, and the cigarette is placed in the cigarette heating tube;
wherein, the nozzle holder is contained in the left cavity of the sealing fixer; the right cylindrical cavity of the piston support is contained in the right cavity; the sealing fixer sliding slot and the nozzle holder guide slot are configured to overlap each other; the connection portion of the piston support is allowed to pass through and slide upwards and downwards in the sealing fixer sliding slot and the nozzle holder guide slot; the left cylindrical cavity of the piston support is contained in the cylindrical inner cavity of the nozzle holder; a top end of the left cylindrical cavity is appressed or not appressed with the roof of the cylindrical inner cavity; the lateral gas channel is closed when the top end of the left cylindrical cavity is appressed with the roof, and the lateral gas channel is opened when the top end of the left cylindrical cavity is not appressed with the roof.

2. The press puffing device according to claim 1 , wherein a sealing ring is sleeved between the left cylindrical cavity of the piston support and the cylindrical inner cavity of the nozzle holder.

3. The press puffing device according to claim 1 , wherein a spring is contained in the right cavity of the sealing fixer; a first end of the spring abuts against a lower end wall of the right cylindrical cavity of the piston support; and a second end of the spring abuts against a bottom wall of the sealing fixer.

4. The press puffing device according to claim 1 , wherein a radial inner edge is provided in a top opening of the left cylindrical cavity of the piston support.
