Description

Technical Field

[0001] This invention relates to a heating non-combustion device based on a thermal energy compensation system and its heating method. Background Technology

[0002] A currently used low-temperature heated tobacco device includes a heating chamber, a power supply, and a circuit board. The circuit board is connected to the power supply. A pin is installed inside the heating chamber. The pin is a resistive heating element and is connected to the circuit board. The circuit board controls the heating power of the pin. In use, tobacco (cigarette) is placed in the heating chamber, and the pin is inserted into the center of the tobacco. The pin is energized and heats up, heating the tobacco. The heat is transferred from the pin to the tobacco and slowly diffuses outward from the center of the tobacco. Because the pin is located in the center of the tobacco, the temperature in the center of the tobacco is the highest, which can easily cause the tobacco in the center to burn, while the surrounding tobacco has not yet been heated and atomized.

[0003] To address the aforementioned issues, another type of heat-not-burning device for low-temperature tobacco differs from the one described above in that a heating layer is installed on the inner wall of the heating chamber. This design ensures that when the tobacco is inserted into the heating layer within the heating chamber, the outer wall of the tobacco is already in close contact with the inner wall of the heating layer. This facilitates the transfer of heat generated by the heating layer to the outer wall of the tobacco, allowing heat to be transferred from the outside in. The pin at the center of the heating chamber heats up together with the heating layer, heating the tobacco from the inside out. This internal-external heating method has the following problems: because the temperature of the pin is transferred from the inside to the outside of the tobacco, when the temperature reaches the outer surface of the tobacco, the tobacco (and its packaging paper) on the outer surface will be pushed outward, pressing the tobacco and packaging paper tightly against the inner wall of the heating layer. This will cause the heating layer to scorch the outer surface of the tobacco, and the center of the tobacco will inevitably be scorched by the pin as well. This method of scorching the tobacco from the inside out is unacceptable. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a heating non-combustible device and its heating method based on a thermal energy compensation system, which has the characteristics of heat compensation supply, low-temperature rapid heating of tobacco, and prevention of scorching.

[0005] This invention is implemented as follows: a heating non-combustion device based on a thermal energy compensation system, comprising:

[0006] A tobacco heating chamber having a first heating temperature;

[0007] A thermal energy compensation cavity is provided with a pressure sensor and a temperature sensor. The pressure sensor is used to detect pressure changes in the thermal energy compensation cavity, and the temperature sensor is used to detect temperature changes in the thermal energy compensation cavity. The thermal energy compensation cavity has a heating element, and the heat generated by the heating element is ΔT.

[0008] A connector connects the thermal energy compensation chamber and the tobacco heating chamber. The connector is used to transfer the heat energy ΔT generated in the thermal energy compensation chamber to the tobacco heating chamber. Under the combined action of the first heating temperature and the heat energy ΔT, the tobacco in the tobacco heating chamber produces aerosol.

[0009] Furthermore, a connecting mesh is provided in the connecting body, and multiple mesh holes are provided in the connecting mesh, through which the heat energy of ΔT enters the tobacco heating chamber.

[0010] Furthermore, the thermal compensation cavity includes multiple preheating cavities, each of which has a heating element, a pressure sensor, a temperature sensor, and a flow sensor.

[0011] Furthermore, the tobacco heating chamber is an electromagnetic induction heating chamber, which includes a heat insulation layer, an induction layer, an induction coil, and a temperature sensor. The induction coil is sleeved around the heat insulation layer, and the heat insulation layer is sleeved around the induction layer. The induction coil and the temperature sensor are connected to a circuit board. The heating element of the thermal compensation chamber is a heating wire, and the heating wire is connected to a control board.

[0012] Furthermore, the tobacco heating cavity is an electromagnetic induction heating cavity, which includes a first heat insulation layer, a first induction layer, and a first induction coil. The first induction coil is sleeved around the first heat insulation layer, and the first heat insulation layer is sleeved around the first induction layer. The first induction coil is connected to a first circuit board. The heating element of the heat compensation cavity is also an electromagnetic induction heating cavity, which includes a second heat insulation layer, a second induction layer, and a second induction coil. The second induction coil is sleeved around the second heat insulation layer, and the second heat insulation layer is sleeved around the second induction layer. The second induction coil is connected to a second circuit board.

[0013] A heating method for a non-combustible heating device based on a thermal energy compensation system includes the following steps:

[0014] a. The pressure sensor and temperature sensor respectively detect the initial pressure P1 and initial temperature T1 in the thermal energy compensation cavity, and the volume of the thermal energy compensation cavity is defined as V;

[0015] b. Based on the required heat energy ΔT to be generated by the heating element, calculate the preheating pressure P2 and preheating temperature T2 that the heating element needs to heat the air in the heat energy compensation cavity.

[0016] c. Calculate the compensation energy ΔW1 required for the air pressure in the thermal compensation cavity to increase from P1 to P2 and the air temperature to increase from T1 to T2. Use this to determine the heating time Δt1 of the heating element in the thermal compensation cavity. Δt1 = f(P1, P2, T1, T2, V, ΔW). After heating for Δt1 time, stop heating.

[0017] Furthermore, after the air pressure and temperature in the thermal compensation cavity change, the pressure sensor and temperature sensor continue to detect the pressure P3 and temperature T3 in the thermal compensation cavity, respectively. Based on the heat energy required by the heating element to generate ΔT, the preheating pressure P4 and preheating temperature T4 that the heating element needs to heat the air in the thermal compensation cavity to again are calculated. The compensation electrical energy ΔW2 required for the air pressure in the thermal compensation cavity to change from P3 to P4 and the air temperature to change from T3 to T4 is calculated. Based on this, the heating time Δt2 of the heating element in the thermal compensation cavity is determined, Δt2 = f(P3, P4, T3, T4, V, ΔW2). After heating for Δt2 time, heating is stopped.

[0018] This invention relates to a tobacco heating chamber with a first heating temperature; a heat compensation chamber containing a pressure sensor and a temperature sensor. The pressure sensor detects pressure changes within the heat compensation chamber, and the temperature sensor detects temperature changes within the heat compensation chamber. The heat compensation chamber includes a heating element that generates heat ΔT; and a connector connecting the heat compensation chamber and the tobacco heating chamber. The connector transfers the heat ΔT generated in the heat compensation chamber to the tobacco heating chamber. Under the combined action of the first heating temperature and the heat ΔT, the tobacco in the tobacco heating chamber atomizes. The heat ΔT generated by the heat compensation chamber is compensated for by the connector and transferred to the tobacco heating chamber. In the tobacco heating chamber, under the combined action of the first heating temperature and the heat ΔT, the tobacco atomizes. The two heat sources generate heat in parallel, enabling rapid atomization (fragrance) of the tobacco. The heat ΔT enters the tobacco along a direction parallel to the tobacco, effectively preventing the outer surface of the tobacco from being scorched. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 A perspective view provided for this invention;

[0021] Figure 2 A cross-sectional view provided for this invention. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-2 This invention provides a heat-not-burning device based on a thermal energy compensation system, comprising: a tobacco heating chamber 1 having a first heating temperature; a thermal energy compensation chamber 2 having a pressure sensor and a temperature sensor installed therein, the pressure sensor being used to detect pressure changes in the thermal energy compensation chamber 2, and the temperature sensor being used to detect temperature changes in the thermal energy compensation chamber 2, the thermal energy compensation chamber 2 having a heating element 21, the heat generated by the heating element 21 being ΔT; and a connector 3 connecting the thermal energy compensation chamber 2 and the tobacco heating chamber 1, the connector 3 being used to transfer the heat energy ΔT generated in the thermal energy compensation chamber 2 to the tobacco heating chamber 1, under the combined action of the first heating temperature and the heat energy ΔT, causing the tobacco 5 in the tobacco heating chamber 1 to produce aerosol.

[0024] A connecting mesh 4 is provided in the connecting body 3, with multiple mesh openings. Heat energy ΔT enters the tobacco heating chamber 1 through these openings. The multiple mesh openings in the connecting mesh 4 compensate for the heat energy passing through the chamber 2, specifically manifested as a hot airflow passing through the mesh openings. The hot airflow moves from bottom to top, entering the tobacco heating chamber 1 through the multiple mesh openings. The effective area for the hot airflow in the connecting mesh 4 matches the cross-sectional size of the tobacco 5 (cigarette stick). This effectively prevents the outer part of the tobacco 5 from scorching against the inner wall of the tobacco heating chamber 1, because the hot airflow in the connecting mesh 4 flows directly upwards. The heat generated at the point where the inner wall of the tobacco heating chamber 1 contacts the tobacco 5 is transferred inwards horizontally, preventing outward expansion that could compress the outer part of the tobacco 5 against the inner wall of the tobacco heating chamber 1, thus avoiding scorching of the outer part of the tobacco 5. Simultaneously, it also effectively prevents scorching at the center of the tobacco 5.

[0025] The thermal energy compensation cavity 2 includes multiple preheating cavities. Each preheating cavity has a heating element 21, a pressure sensor, a temperature sensor, and a flow sensor, which facilitates the separate operation of the heating element 21 to generate heat, thereby improving the heat generation efficiency and shortening the time required to generate ΔT of thermal energy.

[0026] The tobacco heating chamber 1 is an electromagnetic induction heating chamber, which includes a heat insulation layer 11, an induction layer 12, an induction coil 13, and a temperature sensor. The induction coil 13 is sleeved around the heat insulation layer 11, and the heat insulation layer 11 is sleeved around the induction layer 12. The induction coil 13 and the temperature sensor are connected to a circuit board. The heating element 21 of the thermal energy compensation chamber 2 is a heating wire, which is connected to a control board. The upper tobacco heating chamber 1 adopts electromagnetic induction heating, which has a fast heating speed and is convenient for quickly heating the tobacco. It is convenient for the tobacco heating chamber 1 to maintain a first heating temperature. The first heating temperature is lower than the combustion temperature of the tobacco, so the tobacco cannot be ignited. The tobacco can be kept in a high-fidelity state, which is only missing the heat energy ΔT in the thermal energy compensation chamber 2. When the heat energy ΔT in the thermal energy compensation chamber 2 enters the tobacco heating chamber 1, the heat energy ΔT and the heat energy generated by the first heating temperature are mixed together to evaporate the aroma in the tobacco for human consumption.

[0027] Furthermore, the tobacco heating cavity 1 is an electromagnetic induction heating cavity, which includes a first heat insulation layer, a first induction layer, and a first induction coil. The first induction coil is sleeved around the first heat insulation layer, and the first heat insulation layer is sleeved around the first induction layer. The first induction coil is connected to a first circuit board. The heating element of the heat compensation cavity 2 is also an electromagnetic induction heating cavity, which includes a second heat insulation layer, a second induction layer, and a second induction coil. The second induction coil is sleeved around the second heat insulation layer, and the second heat insulation layer is sleeved around the second induction layer. The second induction coil is connected to a second circuit board. The working principle of this design is the same as above.

[0028] A heating method for a non-combustible heating device based on a thermal energy compensation system includes the following steps:

[0029] a. The pressure sensor and temperature sensor respectively detect the initial pressure P1 and initial temperature T1 in the thermal energy compensation cavity 2. The volume of the thermal energy compensation cavity 2 is defined as V (initial pressure P1 and initial temperature T1 are also the pressure and temperature at room temperature).

[0030] b. Based on the required heat energy ΔT to be generated by the heating element, calculate the preheating pressure P2 and preheating temperature T2 that the heating element 21 needs to heat the air in the heat energy compensation cavity 2. The preheating pressure P2 and preheating temperature T2 are the pressure and temperature that need to be reached by heating, also known as the target pressure and target temperature.

[0031] c. Calculate the air pressure in the thermal compensation cavity 2 from P1 to P2. The values ​​of P1 and P2 can be equal or unequal. We will describe the two cases separately. If the thermal compensation cavity is open, the values ​​of P1 and P2 are equal. If the thermal compensation cavity is closed, that is, it is open when air is introduced and closed when air is introduced, the values ​​of P1 and P2 are unequal. The compensation electrical energy ΔW1 required for the air temperature to change from T1 to T2 is used to determine the heating time Δt1 of the heating element 21 in the thermal compensation cavity 2. Δt1 = f(P1, P2, T1, T2, V, ΔW). After heating for Δt1, heating is stopped.

[0032] After the air pressure and temperature in the thermal compensation cavity 2 change, the pressure sensor and temperature sensor continue to detect the pressure P3 and temperature T3 in the thermal compensation cavity 2, respectively. Based on the heat energy required by the heating element ΔT, the preheating pressure P4 that the heating element 21 needs to heat the air in the thermal compensation cavity 2 to is calculated. The values ​​of P3 and P4 may be equal or unequal, depending on whether the thermal compensation cavity 2 is open or closed. The values ​​of P1 and P2 can be used as a reference. The preheating temperature is T4. The compensation energy ΔW2 required for the air pressure in the thermal compensation cavity 2 to change from P3 to P4 and the air temperature to change from T3 to T4 is calculated. The heating time Δt2 of the heating element 21 in the thermal compensation cavity 2 is determined in this way. Δt2 = f(P3, P4, T3, T4, V, ΔW2). After heating for Δt2 time, heating is stopped. P4 and T4 are equal to the preheating pressure P2 and the preheating temperature T2, respectively. This cycle continues. The amount of heat energy ΔT required by the heating element each time may be the same or different, because the amount of heat absorbed from the heat compensation chamber 2 is different each time. This requires that after each inhalation, air is replenished into the heat compensation chamber. The pressure sensor and temperature sensor continue to detect the pressure Pn and temperature Tn inside the heat compensation chamber 2, respectively, to determine the temperature Tn+1 and the pressure Pn+1 that need to be raised. In principle, the temperature Tn+1 and the pressure Pn+1 that need to be raised are equal to the preheating temperature T2 and the preheating pressure P2, respectively, to achieve cyclical heat compensation and ensure that the heat energy reached after each compensation is equal, thus ensuring the consistency of the tobacco flavor in each subsequent inhalation.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
