The application begins below.

First, please refer to the overall structural diagram of the heating unit assembly 100 shown in FIG. 1, and a perspective structural view of the heating unit assembly 100 shown in FIG. 2.

As shown in FIG. 1 , the heating unit assembly 100 is tubular, and the housing of the heating unit assembly 100 includes an insulating layer 101 and a heating layer 102 from the outside to the inside. The heat insulating layer 101 can be made of a heat insulating material, and the heating layer 102 is provided. There is a heating circuit, which can generate heat when energized, and performs heating work. The hollow cavity formed by the heating layer 102 is used for inserting a flue-cured tobacco, and the hollow cavity is generally cylindrically shaped to fit the rod-shaped flue-cured tobacco.

It can be understood that the heating unit assembly 100 is used in a flue-cured tobacco device, and the flue-cured tobacco device is provided with a battery assembly and a control circuit. The positive and negative electrodes of the battery assembly can pass through the positive electrode lead, the negative electrode lead and the positive electrode lead 103 of the heating layer 102, and the negative electrode lead 104, respectively. Forming an electrical connection, under the control of the control circuit, the battery assembly provides the required working power to the heating layer 102, so that when the user inserts the flue-cured tobacco in the flue-cured tobacco, the flue-cured tobacco is inserted into the heating unit assembly 100, and is heated. The layer 102 is energized and heated to heat the flue-cured tobacco in the heating layer 102, and the heat insulating layer blocks the heat radiated from the heating layer 102 from being transmitted to the periphery of the heating unit assembly 100.

The positive electrode lead 103 and the negative electrode lead 104 of the heating layer 102 may pass through the layer body of the heat insulating layer 101 as shown in FIG. 1 and FIG. 2, or may be heated from the axial direction of the heating unit assembly 100. Either one end of the layer 102 is taken out together or the two ends are respectively taken out, which is not limited herein.

It is apparent that the heating unit assembly 100 is provided with a heat insulating layer 101 outside the heating layer 102 by the above arrangement. Therefore, while the heating layer 102 heats the tobacco smoke, the heating unit assembly 100 can effectively block the heating layer 102 from being emitted. The heat is transferred to the periphery of the heating unit assembly 100, so that the toaster does not need to be provided with a heat insulating material around the heating unit assembly 100, so that the heating unit assembly 101 itself can transmit heat to the outside.

It can be understood that the heating part assembly 100 does not need to be matched with the heat insulating material in this arrangement, further facilitates the assembly of the heating part assembly 100 on the tobacco hood, and also saves the arrangement space required for the heat insulating material, thereby facilitating the tobacco hood. The arrangement of the components around the heating assembly 100, such as the structural design of the structural design of the flue-cured casing, and the like.

It is worth mentioning that in the heating unit assembly 100 provided by the present application, the heating layer 102 heats the flue-cured tobacco branch from the peripheral wall of the flue-cured tobacco branch and heats the flue-cured tobacco from the outside to the inside, compared to heating in the existing flue-curing device. The heating part assembly in the form of a sheet is inserted into the flue-cured tobacco branch, and the heating method of heating the flue-cured tobacco branch from the inside to the outside, in this manner, the heating area of the flue-cured tobacco branch of the heating unit assembly 100 can be greatly improved, and the flue-cured tobacco branch can also be The heating is more uniform, not only the burning power of the flue-cured tobacco is not easy to be burned under the same heating power, but also the heating efficiency of the flue-cured tobacco branch is improved, and the heating of the flue-cured tobacco branch is more fully and deeply penetrated to generate more rich and fragrant smoke. For users to use, therefore, the user's experience is higher.

In a practical application, the heating unit assembly 100 can further perform various optimizations, such as:

In one possible implementation, along the axial direction of the heating unit assembly 100, the heating layer 102 includes at least two sub heating layers 1021, another overall structural view of the heating unit assembly 100 as shown in FIGS. 3 and 4, respectively. And the schematic view of the perspective structure, the heating unit assembly 100 is provided with four heating regions S1, S2, S3 and S4, correspondingly, the heating layer 102 is respectively provided with four sub heating layers 1021, the sub heating layer 1021 can be separately from the battery assembly of the flue-cured tobacco The working power source is obtained, so that the heat can be separately energized, and the heating heating of the flue-cured tobacco branch by the heating layer 102 and the adjustment of the heating efficiency are realized.

The number of the heating regions, correspondingly, the sub-heating layer 1021 can also be set to two, three, five, and the like, which is not limited herein.

As mentioned above, the heating unit assembly 100 provided by the present application, the heating layer 102 can achieve higher heating efficiency for the flue-cured tobacco, and therefore, this means that the smoke generation time of the flue-cured tobacco will be shortened. The smoke generation time of the flue-cured tobacco can be shortened. After the heating layer 102 is set as the plurality of sub-heating layers 1021, the battery assembly supplies power to the sub-heating layer 102 according to a preset power supply mode under the control of the control circuit. Therefore, the segmented heating of the flue-cured tobacco branch can not only maintain the full and deep heating of the flue-cured tobacco, but also prolong the smoke generation time of the flue-cured tobacco, so as to provide a longer smoke output time for the user to smoke. More smoke for a longer time.

Moreover, under this setting, the flue-cured tobacco branch can also be arranged with different flavors of tobacco material, so that when the sub-heating layer 1021 heats the flue-cured tobacco branch in stages, the flue-cured tobacco can also output different flavors of smoke for the user to smoke. To further enhance the user experience.

In another possible implementation manner, the sub-heating layer 1021 may further include at least two sets of sub-heating circuits 10211, and each group of sub-heating circuits 10211 can separately obtain working power from the battery components of the flue-curing device, thereby respectively energizing and heating.

In a further possible implementation, in the axial direction of the heating unit assembly 100, similar to the positive electrode lead 103 and the negative electrode lead 104 of the heating layer 102, the sub heating layer 1021 is respectively provided with a positive electrode lead 103 and a negative electrode at both ends. The lead wire 104, the positive electrode lead 103 and the negative electrode lead 104 pass through the layer body of the heat insulating layer 101 and are taken out. With this arrangement, the power supply lead of the sub heating layer 1021 is more easily arranged separately, and the independent heating between the sub heating layers 1021 is ensured. jobs.

It can be understood that the positive and negative electrodes of the sub-heating layer 1021 lead to the positive electrode lead 103 and the negative electrode lead 104, and the soldering points/welding holes reserved in the heat insulating layer 101 can be realized by welding, which can greatly ensure the positive electrode lead 103 in practical applications.

Alternatively, the positive electrode lead 103 and the negative electrode lead 104 may be respectively disposed at the positive electrode and the negative electrode of the sub heating layer 1021 by using a soldering method, and then the high temperature condition in the subsequent sintering process is utilized to make the positive electrode of the sub heating layer 1021 be naturally electrically connected. The positive electrode lead 103 and the negative electrode are naturally electrically connected to the negative electrode lead 104.

Of course, if the sub-heating layer 1021 is not provided in the heating layer 102, the positive electrode lead 103 and the negative electrode lead 104 may be electrically connected in the above manner, and details are not described herein.

Further, on the basis of the above, in order to facilitate reducing the occupied space of the power lead of the sub-heating layer 1021, as shown in an expanded view of the heating unit assembly 100 shown in FIG. 6, the adjacent sub-heating layer 1021 may also share a positive electrode. Lead 103 or negative lead 104.

In another possible implementation manner, the heating layer 102 may specifically be a printed resistor. It can be understood that the printed resistor can be realized by printing a circuit with a higher resistivity on a printed circuit board (PCB), thereby When the current is flowing, a large amount of heat energy can be generated to heat the flue-cured tobacco.

The advantages of power saving and safety, especially in terms of safety performance, the PTC heating element will not cause "redness" in any application, thus avoiding the safety hazard of scalding users.

In another possible implementation manner, the heat insulation layer 101 can be made of a ceramic material or a heat insulating material such as a steel material. It can be understood that the ceramic material and the steel material have a low heat transfer coefficient, thereby effectively blocking the heating layer. The excess heat, particularly the ceramic material, is transferred to the periphery of the heating unit assembly 100. The heat transfer coefficient can be greatly reduced by different formulations or processing techniques, thereby ensuring that excess heat is not transmitted from the insulating layer 101 to the surroundings.

Further, the heat insulation layer 101 is from the outside to the inside, and may further include at least two sub-insulation layers, and the insulation materials used in the adjacent sub-insulation layers may be different from each other, thereby forming the thermal insulation layer 101 of the composite structure. Or, the adjacent sub-insulation layer can also use the same heat insulating material to increase the thickness of the heat insulation layer 101, thereby enhancing the heat insulation effect of the heat insulation layer 101, that is, the sub-insulation layer can be made of ceramic material or steel. Any one of insulating materials such as materials is used.
