Heat-not-burn device based on heat compensation system and heating method thereof

Abstract

The invention provides a heat-not-burn device based on a heat compensation system, comprising: a tobacco heating chamber having a first heating temperature; a heat compensation chamber in which a pressure sensor and a temperature sensor are arranged, wherein the pressure sensor is used for detecting a pressure change in the heat compensation chamber, the temperature sensor is used for detecting atemperature change in the heat compensation chamber, the heat compensation chamber has a heater, and the heater produces heat delta T; a connector that connects the heat compensation chamber and the tobacco heating chamber, wherein the connector is used for transmitting the heat delta T produced in the heat compensation chamber into the tobacco heating chamber; under the joint action of the firstheating temperature and the heat delta T, tobacco in the tobacco heating chamber produces aerosol. A heating method herein is a compensation heat supply mode, enabling tobacco to produce aerosol quickly; it can be effectively prevented that tobacco is scorched.

Description

technical field [0001] The invention relates to a heat-not-burn device based on a thermal energy compensation system and a heating method thereof. Background technique [0002] A heat-not-burn device currently used for low-temperature tobacco includes a heating chamber, a power supply, and a circuit board. The circuit board is connected to the power supply, and a pin is arranged in the heating chamber. The circuit board controls the heating power of the pins. When in use, put the tobacco (cigarette) into the heating chamber, insert the pins into the center of the tobacco, and heat the pins when they are energized to heat the tobacco. Through heat transfer, The heat is transmitted from the pin to the tobacco, and spreads slowly outward from the center of the tobacco. Since the pin is located in the center of the tobacco, the temperature at the center of the tobacco is the highest, which can easily cause the tobacco at the center of the tobacco to burn. But the surrounding to...

[0002] A heat-not-burn device currently used for low-temperature tobacco includes a heating chamber, a power supply, and a circuit board. The circuit board is connected to the power supply, and a pin is arranged in the heating chamber. The circuit board controls the heating power of the pins. When in use, put the tobacco (cigarette) into the heating chamber, insert the pins into the center of the tobacco, and heat the pins when they are energized to heat the tobacco. Through heat transfer, The heat is transmitted from the pin to the tobacco, and spreads slowly outward from the center of the tobacco. Since the pin is located in the center of the tobacco, the temperature at the center of the tobacco is the highest, which can easily cause the tobacco at the center of the tobacco to burn. But the surrounding tobacco has not been heated and atomized

[0003] As an example to solve the above problems, there is also a heat-not-burn device for low-temperature tobacco. The difference between it and the above is that a heating layer is arranged on the inner wall of the heating chamber. At that time, the outer wall of the tobacco has been in close contact with the inner wall of the heating layer, because it is convenient for the heat generated by the heating layer to transfer to the outer wall of the tobacco, and it is convenient to transfer heat from the outside to the inside, and the pin at the center of the heating cavity and the heating layer are Together, the pins heat the tobacco from the inside to the outside. This internal and external heating method has the following problems. Since the temperature of the pins is transmitted from the inside to the outside in the tobacco, when the temperature reaches the outer surface of the tobacco, The tobacco (and the tobacco wrapping paper) located on the outer surface will be pushed outwards, and the tobacco and the wrapping paper on the outer surface will be tightly attached to the inner wall of the heating layer, which will cause the outer surface of the tobacco to be burnt by the heating layer , and the center of the tobacco will inevitably be burnt by the pins. This way of burning the tobacco inside and outside is not advisable
