Non-combustible type tobacco aspirator based on PTC (Positive Temperature Coefficient) ceramic heating

Abstract

The invention discloses a non-combustible tobacco aspirator based on PTC ceramic heating, which comprises a housing, PTC ceramic and a power source arranged at the rear part of the housing, wherein a tobacco heating cavity is formed in the center of the ceramic; airflow passages are indwelled between the power source and the housing; a fan and an airflow control component are arranged between the power source and the heating cavity; the tobacco heating cavity and the fan are simultaneously controlled through the component; a filter tip is arranged at the front end of the tobacco heating cavity; a net orifice plate is arranged between the filter tip and the tobacco heating cavity; air intake net holes are formed in the bottom of the device. During use, a tobacco products is put in the tobacco heating cavity, heating of the tobacco product is controlled through the airflow control component, and the tobacco product is conveyed through the fan; volatile matters generated by the tobacco product get into the oral cavity via the filter tip to enable the smoker to obtain the feeling of satisfaction. The device has the maximal characteristics of constant temperature heating, no naked fire, safety, zero contamination, high heat conversion rate and long natural service life. The device conforms to smoking and consumption habits of people, can avoid naked fire caused by burning of tobacco, can reduce the harm of passive smoking, and has potential market competitiveness.

Description

technical field [0001] The invention relates to an appliance used in the field of heating non-combustion tobacco, in particular to a non-combustion tobacco smoking device based on PTC ceramic heating. Background technique [0002] PTC ceramic heating is a common heating method in industry and people's daily life. Constant temperature heating PTC thermistor has constant temperature heating characteristics. The surface temperature of the PTC thermistor will maintain a constant value, which is only related to the Curie temperature of the PTC thermistor and the applied voltage, but has nothing to do with the ambient temperature. [0003] PTC heater is a heating device designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In small and medium power heating occasions, PTC heater has constant temperature heating, no open flame, high heat conversion rate, minimal influence by power supply voltage, and long natural life. The advan...
