The heating assembly (heating body) is the core component of the low-temperature cigarette smoking set and is the main determining factor of the endurance and service life of the smoking set. The existing heating assembly generally has the problems of easy breakage or high energy consumption. This is because in order to ensure that it is not broken during use, the heating element needs to have a certain volume or mass. This results in the heating element absorbing part of the heat when heating the cartridge, which increases the energy consumption and increases the preheating time. The existing heating body is generally of a solid structure, and the strength / mass ratio is relatively low, and the mechanical properties of the material are not fully utilized. SUMMARY

[0003] Therefore, the primary object of the present application is to provide a sleeve type heating assembly and a heat-not-burn atomizer, in which the heating tubes and the insulators are alternately nested, thereby improving the problem of easy breakage of the sheet type heating body due to the large change in bending strength with direction, and achieving good results.

It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

The terms "horizontal", "vertical", "overhanging" and the like do not mean that the parts must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The sleeve-type heating assembly of this invention includes multiple heating tubes, an insulator, a fixed base, and a head component. The diameter of each heating tube varies from large to small, and the heating tubes are installed on the fixed base in a nested manner from large to small. The heating tubes are connected in series and / or in parallel. An insulator is provided between two adjacent heating tubes. The head component is located at the end of each heating tube away from the fixed base and is used to guide the outermost heating tube into the aerosol matrix. The heating tubes in this invention adopt a sleeve-type structure, and the heating tube components are encapsulated into one piece by the insulator. This allows the heating assembly to have both low mass and high strength, thus having the advantages of low heat absorption and resistance to deformation, which can improve the endurance and lifespan of the smoking device.

[0032] The heating element can be either a heating circuit or a heating coil.

[0033] The insulator is made of heat-resistant adhesives such as inorganic glue, glass glaze, and ceramic glaze.

[0034] The head component is made of any one of ceramic, glass, or metal.

[0035] To improve heating efficiency, the center lines of all the heating elements are aligned on the same straight line. Typically, the heating elements are made using heating coils. An insulating material is plated around the outer periphery of each heating element to form an insulator, and gaps are left between the heating elements, which are filled with insulating material to form the insulator.

[0036] The two adjacent heating elements are electrically connected and fixed together by solder joints.

[0037] Two leads are extended from the heating element to connect to the circuit. One end of one lead is electrically connected to the innermost heating element, and the other end extends out of the fixed base. One end of the other lead is electrically connected to the outermost heating element, and the other end extends out of the fixed base.

[0038] The head component includes a pointed cone and a rod-shaped body, one end of which is connected to the straight end of the pointed cone. The rod-shaped body is used to insert into the heating tube or the insulator, and the pointed cone is used to guide the aerosol matrix into the heating tube.

[0039] The outer edge of the straight end of the cone is flush with the surface of the outermost heating tube.

[0040] The heated non-combustible atomizer of the present invention includes a main unit, a cigarette holder, and the aforementioned sleeve-type heating element. The cigarette holder has a receiving cavity for accommodating the aerosol matrix. The fixed base is mounted on the cigarette holder and causes the heating element to extend into the receiving cavity. The battery on the main unit is used to electrically connect to the heating element.

[0041] For components such as the main unit and the cigarette holder, existing parts can be used. The main unit and the cigarette holder can be made using existing technology, so they will not be elaborated on here.

[0042] The present invention will now be described in detail with reference to specific implementations.

[0043] Combination Figures 1-3 As shown, the sleeve-type heating assembly implemented by the present invention includes a support frame 1, an insulating film 2, a heating tube 3, and a wire 4. The support frame 1 has a pointed tip 11 and a rod-shaped rod 12. The pointed tip 11 is exposed, while the rod 12 is covered by the insulating film 2 and the heating tube 3. The heating tube 3 has multiple layers, and each layer of heating tube 3 is a tube with a circular cross-section. Multiple heating tubes 3 are sleeved on the outside of the rod 12 of the support frame below the pointed tip 11. The heating tubes 3 are arranged in layers around the rod 12 of the support frame. At the same time, the adjacent heating tubes 3 and the heating tubes 3 and the support frame 1 are separated by the insulating film 2.

[0044] The heating element 3 and the insulating film 2 are nested alternately, which improves the problem that the plate heating element is prone to breakage due to the large change in bending strength with direction, and has a better effect.

[0045] In this way, the insulating film 2 (or an insulating tube) fixes multiple heating tubes 3 and the support frame 1 into a whole, and the heating tubes 3 are connected to wires 4.

[0046] like Figure 3 As shown, adjacent heating tubes 3 are connected at the top or bottom by solder joints 5 (e.g., Figure 4 As shown in the figure, all heating tubes 3 can be connected in series to facilitate their combined heating function.

[0047] Therefore, it can be seen that the present invention is a heating assembly composed of alternating nested heating elements and insulating films. In the heating assembly, the pointed end 11 of the support frame is welded to the outermost heating element 3 or connected to the heating element in other ways.

[0048] Two wires 4 are respectively electrically connected with different heating pipes 3, and the heating pipes 3 are in series between each other.

[0049] Generally, the pipe is made of conductive ceramic or heating wire material, and the resistivity ranges from 0.1 μΩcm to 10 μΩcm. The insulating film between the multi-layer pipes can be filled with high-temperature-resistant materials (such as inorganic glue, glass glaze).

[0050] As shown in the figure, in the embodiment, the cross section of the pipe is circular, and in other embodiments, the cross section of the pipe is triangular, quadrilateral, oval, pentagonal or hexagonal, and the specific cross section shape is set as needed.

[0051] As for the realized heating non-combustion atomizer, in addition to the above-mentioned sleeve pipe type heating assembly, it also includes existing main machine, smoke support and other components, wherein the smoke support has a containing cavity for containing aerosol substrate, the fixed base is installed on the smoke support and makes the heating pipe extend into the containing cavity, and the battery on the main machine is used to be electrically connected with the heating pipe.

[0052] The main machine, smoke support and other components are prior art, and will not be described here.

[0053] In summary, the advantages of the present application are as follows:

[0054] 1. The heating assembly realized by the present application adopts a sleeve pipe type structure, and the heating pipe is packaged into an integrated body through an insulator, so that the structure is compact and simple, the manufacturing is convenient, and the manufacturing cost is low.

[0055] 2. The heating assembly with a sleeve pipe type structure can have a lower mass while having a higher strength, and the heating assembly has a higher strength / mass ratio, which can reduce the mass while ensuring the strength, and is beneficial to improve the heating speed and reduce the energy consumption.

[0056] 3. The heating assembly with a sleeve pipe type structure has the advantages of less heat absorption and less deformation, which can improve the endurance and service life of the smoking device.

[0057] 4. The heating assembly has a sleeve pipe type structure, and the structure is compact, so that the overall mass of the heating assembly is small, which is beneficial to improve the heating speed and reduce the energy consumption.

[0058] 5. Moreover, the heating assembly can use the TCR effect of the heating element or the thermocouple welded on the heating element to control the temperature, so that the temperature control has no delay and the temperature control precision is high.

[0059] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
