Abstract

A press-type and nasal-inhaling-type smoking paraphernalia for heating cigarettes includes a roasting-type heating device and a press puffing device, wherein the roasting-type heating device heats the cigarette in the radiated manner; and the press puffing device drives the relevant mechanism to compress the smoke by the user pressing the piston support, and the compressed smoke spurts out from the air outlet for snorting by the user, which avoids the design of the complicated gas channel in the traditional electric heating smoking paraphernalia, the local overheating of the cigarette, and the direct contact of the mouth with the cigarette filter.

First claim

What is claimed is:

1. A press and snorting type smoking paraphernalia for heating cigarettes, comprising:
a roasting-type heating device, comprising:
a cigarette heating tube, wherein a plurality of wall holes are provided on a side wall of the cigarette heating tube;
a heating element, wherein the heating element is arranged on an outer side of the cigarette heating tube and is not in contact with the cigarette heating tube; and
a thermal insulation pipe, wherein the thermal insulation pipe is sleeved on an outer side of the heating element and is not in contact with the heating element, and 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

a press puffing device, comprising:
a piston support, composed of 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; and
a sealing fixer, composed of 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;
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; a side wall of the left cylindrical cavity blocks the lateral gas channel 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 and snorting type smoking paraphernalia for heating the cigarettes 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 and snorting type smoking paraphernalia for heating the cigarettes 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 and snorting type smoking paraphernalia for heating the cigarettes according to claim 1 , wherein a radial inner edge is provided at a top end opening of the left cylindrical cavity of the piston support.

5. The press and snorting type smoking paraphernalia for heating the cigarettes according to claim 1 , wherein a power supply start button and a switch control board are contained in the right cylindrical cavity of the piston support, and are configured to be contactable mutually by contact points between the power supply start button and the switch control board.

6. The press and snorting type smoking paraphernalia for heating the cigarettes according to claim 1 , wherein the heating element is spiral in shape.
