Description

Technical Field

[0001] This application relates to the field of smoker's products technology, specifically to a multi-segment heating element. Background Technology

[0002] Currently, the structure of heating devices for cigarette heating typically involves winding a heating wire around the outer wall of a heat-conducting tube. The cigarette is inserted into the heat-conducting tube, and the heat generated by the heating wire after being energized is transferred to the heat-conducting tube. For example, the cigarette heating device described in patent application CN109222248A, when heating the cigarette without combustion, transfers heat to the heat-conducting tube before acting on the cigarette. This heating effect requires transmission through the heat-conducting tube, resulting in low heating efficiency and slow heating speed. Summary of the Invention

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components.

[0017] Reference Figure 1-2 The present application proposes an embodiment of the multi-segment heating tube, which includes a tube body 10. The inner cavity of the tube body 10 matches the shape of a cigarette. The tube body 10 includes a plurality of connecting parts 20 spaced apart along its axial direction. A heating part 30 is provided between each two adjacent connecting parts 20.

[0018] The cigarette is inserted into the tube 10, and the heating element 30 heats the cigarette inside the tube 10. The heating element 30 is in direct contact with the cigarette for heating, resulting in higher heating efficiency and faster heating speed.

[0019] Based on the above, the connecting part 20 is made of conductive material. The connecting part 20 at one end of the tube body 10 is connected to the first pin, and the connecting part 20 between two adjacent heating parts 30 is connected to the second pin respectively. The first pin and the second pin are used to connect to electrodes with opposite polarities respectively.

[0020] Through the above connection method, multiple heating elements 30 are connected in parallel so that multiple heating elements 30 can be controlled independently, so that each heating element 30 can heat up individually, and two or more heating elements 30 can be controlled to heat up simultaneously.

[0021] For example, the multi-segment heating element can be controlled to start heating from the heating part 30 at one end of the tube body 10. The heating part 30 heats one end of the cigarette. As time goes by, the heat generated by the heating part 30 is gradually transferred to its adjacent connecting part 20, so that the connecting part 20 continues to heat the cigarette. Then, the adjacent heating parts 30 are controlled to heat the cigarette in the same way until the gradual heating from one end of the cigarette to the other end is completed, maintaining the smoking process and improving the user's smoking experience.

[0022] Specifically, the heating element 30 is provided with a hollow structure 40 so that the heating element 30 has a heating circuit structure, which is conducive to generating more heat.

[0023] Referring to the accompanying drawings, the hollow structure 40 in this embodiment includes multiple hollow slots.

[0024] In this embodiment, the heating element 30 uses resistance heating. In another embodiment, the heating element 30 is made of magnetic heating material, including ferromagnetic alloy. Correspondingly, a magnetic coil needs to be set around each heating element 30 on the periphery of the tube body 10. When any magnetic coil is energized, it generates an alternating magnetic field. The magnetic heating material of the heating element 30 corresponding to the magnetic coil heats up under the action of the alternating magnetic field.

[0025] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
