The web 212, which is typically 0.2-0.8mm thick, is formed by stamping or wire cutting at a relatively low cost. The upper relief portion 211 of the metal sheet-like base material 212 can be formed by stamping, thereby further saving the cost. The length, width and other dimensions of the heating element 21 are matched with the diameter and length of the cigarette matched with the heating element, which is beneficial to the sufficient heating of the tobacco.

Preferably, the first end a of the web 212 is provided with a pointed tip 215 facilitating the insertion of the rod 3, the pointed tip 215 guiding the insertion of the heating element 21 and reducing the resistance to insertion.
In order to meet the process requirement of printing the conductive path 214 on the sheet-like substrate 212, the sheet-like substrate 212 includes a flat surface (not shown) between the relief portions 211 at two opposite sides of the heat generating sheet, and the conductive path 214 is printed and formed in the flat surface area. The relief portions 211 are disposed outward from two opposite sides in the width direction of the flat surface.
The insulating layer 213 is formed by covering the surface of the substrate 212 with a glass paste containing silicon oxide, calcium oxide, and aluminum oxide and then sintering at 400-1000 deg.C, and the insulating layer 213 can prevent short circuit between the substrate 212 and the conductive via 214 due to the conductivity of the substrate 212 made of metal or alloy.

In order to prevent the metal sheet substrate 212 from being oxidized during high temperature use, both sides of the sheet substrate 212 are preferably covered with the insulating layer 213. The conductive paths 214 are formed on the insulating layer 213 on one side, the insulating layer 213 may be formed only on one side of the sheet-like substrate 212 for the conductive paths 214, and the insulating layer 213 may be eliminated when the substrate of the heating member 21 is made of a non-metallic non-conductive material.
The conductive path 214 functions as a resistance heater, and may be a conductive layer formed on the insulating layer 213 by physical vapor deposition, or plating or printing.
Preferably, the conductive path 214 includes a heating resistor 2141 and an electrical connection portion electrically connected to the heating resistor 2141, the heating resistor 2141 and the electrical connection portion are arranged along the length direction of the substrate 212, and the conductive electrode 2142 is connected to an external circuit. Preferably, the electrical connection portion includes two conductive electrodes 2142 electrically connected to the heat-generating resistor 2141.
The lead 22 is connected to the conductive electrode 2142 and led out along one end of the heating element 21 away from the heating resistor 2141 in the length direction, that is, the heating resistor 2141 and the conductive electrode 2142 are arranged from the first end a to the second end B, and the lead 22 is led out from the second end B.
The heating resistor 2141 may be formed by printing any one of silver-palladium resistor paste, ruthenium-palladium resistor paste, platinum paste, and nickel-based paste, and then sintering the printed paste. The pattern of the heating resistor 2141 can be flexibly set, and a suitable resistance value required for the heating element 21 can be obtained by matching the characteristics of the paste and the thickness of the heating resistor 2141, and the resistance value of the heating element 21 is generally between 0.3 and 2.0 Ω; the firing resistor 2141 is generally less than 0.1mm thick, preferably less than 20um thick.

When the lead 22 is electrified with an external power supply, the heating resistor 2141 can be electrified to heat, and the lead 22 can be connected with the conductive electrode 2142 in a high-temperature soldering manner under the protective atmosphere of 600-; the lead 22 is connected to the conductive electrode 2142 by soldering with a high temperature solder paste at a use temperature of greater than 300 c.
Since the metal sheet substrate 212 has better thermal conductivity, in order to prevent heat loss, the through hole 2122 is disposed in a length direction section of the sheet substrate 212 where the conductive electrode 2142 is located, and the through hole 2122 can isolate heat, thereby reducing heat transferred to the second end B.
Due to the lower temperature of the corresponding section of the conductive electrode 2142, the tobacco is not sufficiently atomized, where the tobacco shred may store and absorb a certain amount of tobacco tar, thereby preventing or reducing the leakage of tobacco tar therefrom.
The section corresponding to the heating resistor 2141 with the heating element 21 inserted into the tobacco and the section corresponding to the conductive electrode 2142 have a large temperature gradient, the temperature of the section corresponding to the conductive electrode 2142 is relatively low, the heat dissipation is small, and the effective utilization of energy is facilitated.
In order to isolate the heating resistor 2141 from the outside air and further improve the life and stability thereof, the heating element 21 further includes an isolation layer 216 covering the outside of the conductive path 214.
The spacer layer 216 is a layer of glaze fired from a glass glaze and typically has a thickness of less than 0.1 mm. The web 212 is covered on both sides with a release layer 216. The glaze layer makes the surface of the heating element 21 smooth and has smaller roughness, reduces the adhesion of smoke spots and tobacco tar after the tobacco is baked and is convenient to scrub. In other embodiments, the isolation layer 216 may cover only the side of the conductive via 214.
Preferably, as shown in fig. 6, in order to facilitate the insertion of the heating element 21 into the cigarette 3, the width from the first end a to the second end B of the heating element 21 gradually widens, so that the heating element 21 is in a sword shape, the first end a is narrow, and in combination with the thinning structure of the avoiding portion 211, the resistance when the heating element 21 is inserted is small, thereby facilitating the insertion and effectively reducing the tobacco gathered on the side edge of the heating element 21; the widening of heating member bottom is favorable to increasing heating member 21's intensity, prevents that a lot of plug cigarette from leading to the heating member rupture.
Generally, the angle between the widthwise opposite sides of the cusp 215 is greater than the angle between the widthwise opposite sides of the second end B of the heating element 21. In other embodiments, the heating member 21 may also have a triangular shape.
As shown in fig. 2, the mounting seat 23 is disposed on the second end B of the heating member 21, i.e. on the end of the heating member 21 from which the lead 22 is led out, and is disposed on the electrical connection portion. In other embodiments, the mounting base 23 may be a separate component that is separately mounted to the heating member 21.
The prong 215 is located at one end of the heating element 21 away from the mounting seat 23, the mounting seat 23 and the prong 215 are respectively located at two opposite ends of the heating element 21, and after the one end of the prong 215 of the heating element 21 is inserted into the cigarette tube 1, the mounting seat 23 will abut against the outer end of the cigarette tube 1 to limit the insertion depth of the heating element 21.
Since the through hole 2122 is formed in the length-direction section of the sheet-like substrate 212 where the conductive electrode 2142 is located, heat transfer to the second end B is reduced, and the over-temperature of the mounting seat 23 can be prevented.
Since no heating region is disposed between the end portion of the second end B where the mounting seat 23 is located and the conductive electrode 2142, the possibility of generating harmful gas is reduced, the material selection range of the mounting seat 23 is wider, and the cost is reduced. Usually, the mounting seat is injection molded by high molecular polymer, and commonly used materials include polyetheretherketone, high temperature nylon, and the like.
It is to be understood that the above-described respective technical features may be used in any combination without limitation.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
