Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0030] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be connected, or it can be specifically connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected between two groups. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0031] The specific embodiments of the utility model will be described in detail below in combination with the drawings.

[0032] As shown in Figs. 1-3 The utility model provides a novel heating ring, which comprises two conductive bodies 100, a base body 200, a first dielectric layer 300, a heating layer 500 and a second dielectric layer 600 arranged on the base body 200 in sequence, the second dielectric layer 600 is provided with two hole positions 601, and the two conductive bodies 100 pass through the two hole positions 601 respectively and are electrically connected with the heating layer 500 respectively.

[0033] Specifically, the base body 200 is in a cylindrical structure, and the base body 200 can be selected as a hot nozzle, a copper pipe or an alloy pipe structure. The first medium layer 300, the heating layer 500 and the second medium layer 600 are sequentially wrapped on the outer surface of the base body 200. The first medium layer 300 and the second medium layer 600 are both insulating medium layers, and the first medium layer 300 and the second medium layer 600 each include three insulating medium layers. Since the heating layer 500 needs to generate heat by itself, it needs to be powered. The heating layer 500 is sandwiched between the first medium layer 300 and the second medium layer 600, so that when the heating layer 500 is powered, the base body 200 itself will not have a leakage problem. Compared with the traditional method of embedding a heating ring in a groove, this arrangement does not damage the base body 200 and ensures that the overall thickness of the new heating ring is small.

[0034] Further, the heating layer 500 includes a conductor layer 400, the conductor layer 400 is printed on the first medium layer 300 and is electrically connected with the heating layer 500, and the conductor layer 400 is electrically connected with the two conductive bodies 100.

[0035] The conductor layer 400 is provided with two polarity pieces 401, two hole positions 601 are respectively arranged at the two polarity pieces 401, and the two conductive bodies 100 respectively pass through the corresponding two hole positions 601 and are respectively connected with the two polarity pieces 401.

[0036] Specifically, the heating layer 500 is only used for heating, and it needs to be connected to an external power supply to obtain electric energy for heating work. Therefore, the conductor layer 400 and the heating layer 500 need to use a conductive medium. The conductor layer 400 and the heating layer 500 are both printed by thick film technology, so the conductor layer 400 is not directly connected with the external power supply. Here, the two conductive bodies 100 are used as the conductive medium for connecting the conductor layer 400 with the external power supply. In order to further reduce the overall thickness of the new heating ring, the heating layer 500 and the conductor layer 400 are in the same layer, i.e. the first medium layer 300. Of course, the heating layer 500 and the conductor layer 400 can be combined to form the same structure, such as a heating layer structure with a conductor.

[0037] Further, the heating layer 500 includes a plurality of heating resistance pieces 501, and the conductor layer 400 further includes a plurality of connection lead pieces 402. The plurality of heating resistance pieces 501 are connected with the plurality of connection lead pieces 402 to form a heating resistance long strip in series. The first end and the second end of the heating resistance long strip are respectively electrically connected with the two polarity pieces 401. The two polarity pieces 401 are respectively a positive electrode and a negative electrode.

[0038] Specifically, the heating layer 500 and the conductor layer 400 are both printed and sintered sheet structures, which can reduce the thickness of the structure arrangement as much as possible under the premise of realizing the function, and the polar sheet 401, the connecting conductor sheet 402, and the heating resistor sheet 501 are directly printed on the first dielectric layer 300. The structure design and layout of the polar sheet 401, the connecting conductor sheet 402, and the heating resistor sheet 501 can be determined according to user needs. In this embodiment, the heating resistor long strip is connected in series to be wound on the outer surface of the base body 200 to cover the entire base body 200 as much as possible to ensure that the base body 200 is evenly heated at each position. Compared with the traditional inlaid heating ring method, the heating area of the heating ring is difficult to distribute evenly on the base body 200. The arrangement of the heating layer 500 and the conductor layer 400 in this embodiment is simpler and can better ensure that the base body 200 is evenly heated at each position.

[0039] Further, the new heating ring further includes an encapsulation layer 700, which covers the heating layer 500.

[0040] Specifically, the encapsulation layer 700 includes but is not limited to a heat insulation film, which is specifically used to cover the heating layer 500 to retain as much heat generated by the heating layer 500 as possible in the base body 200 to ensure that not too much heat is spilled out, thereby improving the utilization rate of the heat of the heating layer 500.

[0041] Further, the new heating ring further includes a conductor layer 400, which is printed on the encapsulation layer 700 and electrically connected with the heating layer 500.

[0042] Specifically, in another embodiment, the conductor layer 400 can also be arranged on a different layer from the heating layer 500, and conductors are led out from the heating layer 500 or the conductor layer 400 to connect each other. However, in this embodiment, the conductor layer 400 and the heating layer 500 are still in the same layer to reduce the overall thickness of the new heating ring.

[0043] Further, the first dielectric layer 300, the conductor layer 400, the heating layer 500, the encapsulation layer 700, and the second dielectric layer 600 are arranged on the base body 200 by the printed and sintered method in the thick film process, and the total thickness of the first dielectric layer 300, the conductor layer 400, the heating layer 500, the encapsulation layer 700, and the second dielectric layer 600 is less than 0.1 mm.

[0044] The reason is that in the present embodiment, the printing and sintering method in the thick film process is adopted, and the thick film process has a significant cost advantage compared with other high-precision processes. This is mainly due to the relatively simple process steps, lower equipment investment and more economical material cost. Therefore, in large-scale production applications, the thick film process can significantly reduce production costs, improve economic benefits, and more importantly, can control the thickness of the film layer according to actual needs. By controlling the deposition time, temperature, solution concentration and other parameters, the thickness of the film layer can be accurately controlled, and different functional film layers can be prepared, such as corrosion resistance, oxidation resistance, wear resistance, and enhanced adhesion, etc. The overall thickness of the new heating ring can be controlled to be small, and the manufacturing cost can be controlled to be low.

[0045] The above is one or more embodiments provided in combination with specific content, and the specific implementation of the utility model is not limited to these descriptions. Any approximation, similarity or replacement of the method and structure of the utility model, or any technical deduction or replacement under the concept of the utility model, should be considered as the protection scope of the utility model.
