[0003] Currently, heated tobacco devices primarily use a needle-type heating element inserted into the cigarette to heat it, starting from the center of the cigarette and working its way outward. This inner-core heating method concentrates heat within the tobacco, resulting in insufficient heating of the outer tobacco. Furthermore, due to direct contact with the tobacco, the inner-core heating element tends to stick to the tobacco after heating. This causes carbonized tobacco scale to fall into the heating device when the cigarette is removed. The industry urgently needs to develop a new type of heated tobacco device.

[0032] The present invention will be described in detail below with reference to the accompanying drawings:

[0033] As shown in Figures 1-2, the present application provides a heating smoking device, comprising a base 1, a tube 2, and a heating body 3; one end of the base has a mounting surface; the tube is disposed on the mounting surface; and the heating body is mounted in the tube;

[0034] The interior of the heating body 3 is of honeycomb design, with an air inlet at the lower end and an air outlet 33 at the upper end. The tube at the upper end of the heating body forms a receiving cavity for placing cigarettes.

[0035] In the above scheme, the heated tobacco device of the present application heats the tobacco material by heating the air through the heating body to form a hot air flow. The hot air flow has good fluidity, increases the heated area of ​​the tobacco material, and heats the tobacco material more evenly and fully, thereby alleviating the problem of tobacco material fouling and difficulty in cleaning. In addition, compared with straight tubes and S-shaped spiral heating air ducts, the honeycomb structure design inside the heating body of the smoking device of the present application has a better heating effect on the inflowing air. The inflowing air can be diffused and heated in the honeycomb pores. The amount of heated air is large and the heating efficiency is high, so that the air flowing into the air inlet is heated to a hot air flow of the required temperature when it flows out of the honeycomb pore structure inside the heating body. As the user draws, the hot air flow flows from the air outlet to the tobacco section of the cigarette to heat the tobacco material. Preferably, a heat-insulating gap is also reserved between the tube body and the base.

[0036] As a preferred embodiment, the tube body 2 is a sandwich tube body, and the heating body 3 is installed in the tube body 2. The interlayer 21 of the tube body serves as an airflow channel, and the airflow channel is connected to the air inlet at the lower end of the heating body. Specifically, the lower end surface (air inlet end) of the heating body is spaced apart from the mounting surface of the base, and a gap channel for air intake is formed between the two surfaces; that is, the tube body at the lower end of the heating body is formed with a gap channel for air intake, and the airflow channel of the tube body interlayer is connected to the gap channel. The hollow interlayer of the tube body serves as an air intake channel, which does not affect the overall structure of the smoking device. At the same time, it cooperates with the gap channel design at the lower end of the heating body to optimize the air flow path of the air flow, making the air flow and heating more unobstructed.

[0037] As a preferred embodiment, the heating body 3 comprises: a columnar heat-conducting base 31, and a heating plate 32 attached to the side wall of the heat-conducting base. The heating plate can be located on the outer wall of the heat-conducting base or on the inner wall of the heat-conducting base. In this embodiment, it is preferably located on the outer wall of the heat-conducting base to avoid occupying the internal space of the heat-conducting base. The heat-conducting base is made of a high-thermal-conductivity material, including but not limited to ceramic materials such as aluminum oxide and zirconium oxide. The interior of the heat-conducting base has a honeycomb design, with honeycomb channels designed based on the honeycomb structure. The lower end surface of the heat-conducting base is evenly distributed with multiple air inlet holes, and the upper end surface of the heat-conducting base is evenly distributed with multiple air outlet holes 33. Both the air inlet holes and the air outlet holes are connected to the honeycomb structure inside the heat-conducting base. The multiple air inlet holes on the lower end surface of the heat-conducting base serve as the air inlet of the heat-conducting base, and the multiple air outlet holes on the upper end surface of the heat-conducting base serve as the air outlet of the heat-conducting base.

[0038] The electrical system of the smoking device is connected to the heating plate, and the heating plate generates heat when it is powered on. Specifically: the heating plate and the heating circuit in the electrical system are powered on and generate heat. Since the substrate is made of highly thermally conductive material, the substrate temperature rises when the heating plate is continuously powered on and heated, thereby heating the air in the internal honeycomb holes; as the user draws in, the hot air flows through the tobacco section of the cigarette to heat the tobacco material.

[0039] As a preferred embodiment, the upper end surface of the heat-conducting base is further provided with a plurality of thorn blocks 4, which are used to abut against and support the cigarette 6; the thorn blocks are preferably arranged on the side of the air outlet holes, and the thorn blocks are arranged at intervals between the plurality of air outlet holes. The provision of the thorn blocks forms a gap between the tobacco segment end of the cigarette and the air outlet end surface of the heating body, which can better optimize the air path of the hot air flow through the cigarette, make the air flow more smoothly flow into the cigarette for heating, and increase the amount of smoke heated by the cigarette. In this embodiment, the thorn block is a conical structure. When the cigarette abuts against the thorn block, it is easily penetrated by the tip of the upper part of the cone. The increase in the diameter of the lower part of the cone increases the difficulty of continuing to insert the cigarette, limits the amount of cigarette inserted, and naturally forms a gap between the end of the cigarette and the air outlet end surface of the heating body.

[0040] More preferably, the protruding block is a heat-conducting tooth block. Preferably, it is a heat-conducting tooth block with a conical structure. The heat-conducting tooth block is also made of ceramic materials with high thermal conductivity such as alumina and zirconia; multiple heat-conducting tooth blocks form a serrated structure at the air outlet end of the heating body. When the cigarette is inserted, the serrated structure can be partially inserted into the tobacco section of the cigarette, and can directly conduct the heat of the heating body to the tobacco section for heat compensation of the cigarette, accelerate the heating rate of the tobacco section of the cigarette, so as to achieve a better cigarette heating effect, increase the amount of smoke heated by the cigarette, and make up for the problem of insufficient smoke volume in the initial smoking of the cigarette.

[0041] Furthermore, a heat-insulating layer 5 is provided on the inner wall of the tube at the upper end of the heating body. Preferably, the heat-insulating layer is a heat-insulating sleeve, which has a heat-insulating effect and a certain sealing effect on the hot air flow of the heated cigarette.

[0042] The base is equipped with an electrical system 11, which is connected to the heating element and controls the heating of the heating element. Specifically, the electrical system includes a heating circuit, which is electrically connected to the heating plate on the side wall of the heat-conducting base. The smoking device of this application also includes a power supply 12 disposed in the base, which is connected to the electrical system and powers the smoking device. Alternatively, the electrical system is equipped with a power socket for connecting to an external power source.

[0043] It should be noted that the electrical system is existing technology and is set up with reference to existing electric heating devices.

[0044] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
