Problems solved by technology

[0004] The existing ceramic heating elements have the following problems: the heating effect of the alumina ceramic heating element is good, but due to the poor toughness of the alumina ceramic, and in practical applications, the thickness of the heating element should be controlled within 0.5mm and the width is less than 4.9mm ( smaller than the diameter of a cigarette) and the front end of the heating element is sharp, so in actual operation, the existing alumina ceramic element is easy to break and easy to crack when heated; in addition, MCH is used as a cermet heating element today, but it includes tungsten or Molybdenum manganese base metal, when heated, MCH will increase with the increase of temperature, and the resistance value will also increase, which is not conducive to the normal heating of the heating element, so that it will affect the smoker's experience
[0005] Therefore, it is necessary to improve the existing ceramic heating elements to retain the heating efficiency of ceramics and overcome the problems that the existing ceramic heating elements are easy to break and crack

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...

The heating power resistance film is connected with a lead on the lead pad film.The yttrium-doped zirconia heating element further comprises an insulating protecting layer which packages the heating power resistance film. The lead pad film is provided with lead pins which can beelectrically connected with an outer power supply. The yttrium-doped zirconia heating element has advantages of high temperature increase speed, high thermal compensation speed and high thermal response speed. Furthermore, the yttrium-doped zirconia heating element for heating the incombustible low-temperature cigarette has an advantage of easy operation.

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...
