Description

Non-combustion heated smoking apparatus and its heating assembly

FIELD OF THE INVENTION The present invention relates to air heating techniques, and more particularly to non-combustion heating type smoking devices and heating assemblies thereof.

Currently, the hazard of tobacco is one of the most serious public health problems in the world. According to a number of scientific evidences, smoking and secondary smoking exposure (secondhand smoke) have been shown to seriously harm human health. According to statistics from the World Health Organization (WHO), the number of deaths caused by smoking worldwide can be as high as six million people per year, that is, one person per 6 seconds will die from smoking related illnesses, and among smokers Half can die prematurely due to smoking, and the annual number of deaths from non-smokers caused by secondary smoking exposure is about 600,000.

Due to the significant human dependence on tobacco products and the double pressures of health faced by cancer and disease, what is required in the tobacco market is not only to give the smoker the same excitement and joy as traditional cigarettes, To provide a product which can be protected from the above. Non-fired heated tobacco products directly heat the cigarette through a smoking device without generating smoke, so that it can achieve a similar feeling of satisfaction to a conventional cigarette, as well as reduce the generation and ingestion of toxic substances during the combustion process And as a result, it is the most innovative product that can disturb cigarettes.

Generally, smoking devices using non-combustion heating techniques include a heating assembly, which is used to heat the inhaled cold air, and the heated air is the primary energy for drying the tobacco product. However, the conventional heating assembly can not sufficiently heat the inhaled cold air.

Therefore, there is a need to provide a non-burning, heated smoking device and a heating assembly therefor that is capable of sufficiently heating the sucked cold air.

As a heating assembly,

A pipe body having an air inlet at its end;

A heat conducting rod received in the pipe body; And

And a heating wire spirally surrounding the outer side wall of the thermally conductive rod, wherein the outer side wall of the heat ray and the heat conducting rod and the inner wall of the pipe body cooperatively form a guiding passageway.

A non-burning heated smoking device includes the heating assembly described above; And a heating pipe, wherein the heating pipe defines a receiving hole for receiving the tobacco product and is connected to the pipe body.

According to the above-mentioned non-combustion heating type smoking device and its heating assembly, the spiral heat wire, the outer side wall of the heat conducting rod and the inner wall of the pipe body cooperatively form a guiding passage, and therefore the guiding passage is also helical. Cool air is drawn through the air inlet into the pipe body and then flows along the helical guiding passageway. By utilizing the rapid heating characteristics of the hot wire, the hot wire heats the air flow and the heat conducting rod in the guiding passage. After the thermally conductive rod is heated, the heated thermally conductive rod and hot wire heat the cold air sucked through the air inlet, increasing the contact time and contact area between the cold air and the hot and thermally conductive rods, Thereby allowing sufficient heating of the inhaled cold air.

The side wall of the air inflow pipe 200 is hermetically closed. The outlet end (220) communicates with the air inlet (1231). Cold air enters the air inlet tube 200 through the inlet end 210 and is discharged through the air inlet 1231 after being discharged from the outlet end 220 to the pipe body 110 ). Since the side wall of the air inflow pipe 200 is hermetically closed, only the cold air can flow into the pipe body 110 through the outflow end 220 after the cold air enters the inflow end 210 have. During the air conduction process, no air escapes and no other air is mixed, thereby ensuring a clean, non-polluting source of airflow.

The inflow end 210 is provided with a one-way airflow sensor 230, which is used to sense airflow when an inhalation action occurs to record a valid suction count. For example, the one-way airflow sensor 230 may be a unidirectional microphone.

The pipe body 110 may be made of an insulating and thermally conductive material so that the pipe body 110 itself does not generate heat but conducts heat generated by the heat ray 130.

For example, the temperature sensor 150 may be a thermistor such as an NTC (negative temperature coefficient) thermistor. The temperature sensor 150 senses the temperature of the thermally conductive rod 120 and then feedbacks the temperature to a control system (for example, a microcontroller unit). The control system continuously adjusts the supply current according to the program command so that the temperature of the heat conducting rod 120 is always within the controllable range.

The outer side wall of the thermally conductive rod 120 defines a spiral groove 121 and the thermal line 130 extends along the spiral groove 121 to the outside of the thermally conductive rod 120 Spirals around the side wall. The heating wire 130, the outer side wall of the heat conduction rod 120, the spiral groove 121, and the inner wall of the pipe body 110 form a guiding passage 110a. In order to secure the size of the guiding passage 110a, the height of the spiral groove 121 is larger than the diameter of the heat ray 130. [ Since the hot wire 130 is spirally wound around the outer side wall of the thermally conductive rod 120 along the spiral groove 121, the hot wire 130 not only directly heats the airflow, May further increase the temperature of the heat conducting rod 120 and the heated heat conducting rod 120 may also heat the air flow.
