Abstract
Description
technical field
[0001] The invention relates to the technical field of heat-not-burn low-temperature cigarettes, in particular to an yttrium-doped zirconia heating element for heat-not-burn low-temperature cigarettes and a manufacturing method thereof. Background technique
[0002] Heat-not-burn low-temperature cigarettes are cigarettes that heat tobacco through a heat source without igniting the tobacco to produce tobacco-flavored gases. Compared with ordinary combustion cigarettes, heat-not-burn low-temperature cigarettes only produce nicotine in the heated state to adapt and satisfy smoking. The physiological needs and psychological needs of consumers avoid the generation of a large number of harmful compounds such as tar, carbon monoxide, nitrosamines, and some radioactive substances produced when burning cigarettes are burned. In addition, heat-not-burn low-temperature cigarettes have no static sidestream smoke (static sidestream smoke refers to the smoke produced in th...
Examples
Embodiment 1
[0038] A heating element of yttrium-doped zirconia in a heat-not-burn low-temperature cigarette in this embodiment, such as figure 1 As shown, it includes a yttrium-doped zirconia ceramic substrate 1, and an insulating film layer 2 is printed on one surface of the yttrium-doped zirconia ceramic substrate 1 to reduce the friction between the yttrium-doped zirconia ceramic substrate 1 and cigarettes and other parts. One board surface is printed with a wire pad film 3 and a heating power resistance film 4, the heating power resistance film 4 is connected to the wire on the wire pad film 3, and also includes an insulating protection layer 5, and the insulation protection layer 5 covers the heating power resistance film 4. The wire pad film 3 is welded with a lead pin 6 that can be electrically connected to an external power supply, wherein, as figure 2 As shown, the length of the insulating protective layer 5 is shorter than that of the yttrium-doped zirconia ceramic substrate 1 ...
Embodiment 2
[0042] A method for manufacturing a heat-not-burn low-temperature cigarette heating element of yttrium-doped zirconia in this embodiment includes the following steps:
[0043] Step 1, such as image 3As shown, the yttrium-doped zirconia ceramic plate 7 is used, and the yttrium-doped zirconia ceramic substrate 1 is cut on the yttrium-doped zirconia ceramic plate 7, so that the front end of the yttrium-doped zirconia ceramic substrate 1 is sharp; the specific cutting The method is as follows: on the yttrium-doped zirconia ceramic plate 7, the scribed groove 8 is formed to form several yttrium-doped zirconia ceramic substrates 1 and margins 9, and the scribed groove is helpful for subsequent processes to make the yttrium-doped zirconia ceramic plate 7 It is divided into small units, and a single yttrium-doped zirconia ceramic substrate 1 is obtained by splitting the cutting groove 8 .
[0044] Step two, such as Figure 4 As shown, using the thick film film forming technology, a...
