Description

An atomization system and a tobacco rod

Technical field

The invention relates to the field of electronic cigarettes, and in particular to an atomization system and a tobacco rod.

Background technique

Traditional smoking is done by igniting tobacco with an open flame that produces smoke for smokers to smoke. The smoke produced by the burning of tobacco usually contains thousands of harmful substances. Therefore, traditional tobacco not only causes serious respiratory diseases to smokers, but also easily causes second-hand smoke.

In order to solve the technical problem that traditional tobacco combustion produces more harmful substances, the technicians developed atomized electronic cigarettes and electronic flue-cured tobacco. However, the atomized electronic cigarettes form aerosols by atomizing the smoke liquid for smoking by smokers, atomizing Although e-cigarette overcomes the above deficiencies of traditional cigarettes, it can satisfy consumer's dependence on tobacco to a certain extent, but the smoke liquid of e-cigarette is made up of flavor and fragrance, which is not a real cigarette product, and its smoke is light. Lack of tobacco aroma, and can not be widely accepted by consumers. The existing low-temperature electronic flue-cured tobacco uses a low temperature (about 100 degrees Celsius) non-combustion method to heat the shredded tobacco. Since the heating temperature is low, the amount of harmful substances generated by heating is small, but the amount of smoke is obviously insufficient. However, if the tobacco is heated at a high temperature, the tobacco is easily blackened, carbonized, and the heat distribution is uneven, and it is easy to cause a problem that some of the tobacco has been carbonized and the other portion is insufficient in temperature, thereby causing more harmful. substance. How to absorb the aromatic smell of tobacco and to reduce harmful substances to a large extent has become an urgent problem for the tobacco industry.

The atomizing assembly 200 shown in this embodiment is internally provided with a receiving cavity 201, and the inside of the receiving cavity 201 is inserted and fixed with an induction coil assembly 202, wherein the induction coil assembly 202 is made of a conductive material.

In order to enable the atomizing assembly 200 shown in this embodiment to heat the tobacco rod 100 to form smoke, the outer peripheral wall of the end of the tobacco rod 100 is provided with a heating member 101, and the heating member 101 is composed of Made of ferromagnetic material with electrical conductivity.

The specific material of the heating element 101 is not limited in this embodiment. For example, the heating element 101 shown in this embodiment may be a ferromagnetic metal material, such as iron, cobalt, nickel, or the like. For example, the heating element 101 shown in this embodiment may also be a non-metal material, as long as the heating element 101 has ferromagnetism and has certain electrical conductivity, and the resistance value of the heating element 101 is within a preset range. Therefore, the heating member 101 can heat the tobacco rod 100 under the action of electromagnetic heating.

Optionally, when the tobacco rod 100 is produced, the heating element 101 is disposed at an end of the tobacco rod 100, so that the user can set the heating element 101 when the smoke is needed. The tobacco rod 100 is inserted into the atomizing assembly 200 to perform smoking of smoke.
