[0002] A quartz heating tube is a common electrothermal element, which is widely used in industrial and household heating equipment. Its main structure includes a quartz glass tube and a heating wire inside. The heating wire usually has a spiral structure. After the heating wire is electrified, electrical energy can be converted into heat energy and conducted to the outside of the quartz tube, so as to achieve heating.
[0003] In the prior art, the spiral pitch of the heating wire inside the traditional quartz heating tube is often fixed, resulting in the same amount of heat generated in each part of the heating wire. However, in actual applications, the two ends of the quartz heating tube usually absorb more heat due to being close to the metal parts of the equipment, resulting in a lower temperature in the area of the end of the heating wire, so that the heat radiated from both ends of the heating tube is insufficient, while the heating intensity in the middle area of the heating wire is relatively too high, causing uneven heat distribution of the heating tube and affecting the heating effect.
[0004] Therefore, there are defects in the prior art and improvement is needed. Summary of the Utility Model

[0008] Wherein, the length of the first winding section is 0.5 - 0.75 of the length of the heating wire body, and the length of one of the second winding sections is 0.1 - 0.25 of the length of the heating wire body.
[0009] Adopting the above technical solutions, in the heating wire structure applied to a quartz heating tube, the wire diameter of the heating wire body is 0.2 - 0.8 mm.
[0010] Adopting each of the above technical solutions, in the heating wire structure applied to a quartz heating tube, the spiral pitch of the first winding section is 0.6 - 1 mm;
[0011] The spiral pitch of the second winding section is 0.2 - 0.6 mm.

[0025] Embodiment 1
[0026] As Figure 1 and Figure 2 shown, the embodiment of the present utility model provides a heating wire structure applied to a quartz heating tube, including a heating wire body 10 in a spiral structure. The heating wire body 10 has a first winding section 101 and a second winding section 102. The second winding section 102 is located on both sides of the first winding section 101. The spiral pitch D1 of the first winding section 101 is greater than the spiral pitch D2 of the second winding section 102. In this embodiment, the spiral pitch D1 of the first winding section 101 is 0.6 mm, and the spiral pitch D2 of the second winding section 102 is 0.4 mm; the spiral pitch D1 of the first winding section 101 is larger, that is, the heating density in this area is lower and the generated heat is relatively less; the spiral pitch D2 of the second winding section 102 is smaller, the heating density is higher, and the generated heat is more. By adjusting the spiral pitch of the heating wire body 10, the heating tube can generate different amounts of heat in different areas, so as to achieve the effect of balanced heat distribution, and avoid the heat at both ends of the heating wire body 10 being absorbed by the metal components in the heating tube, resulting in local temperature differences, thereby improving the heating uniformity of the quartz heating tube.
[0027] Among them, the length of the first wire-winding section 101 is 0.75 times the length of the heating wire body 10, and the length of one of the second wire-winding sections 102 is 0.125 times the length of the heating wire body 10. In this embodiment, the length of the first wire-winding section 101 is 240 mm, and the length of the second wire-winding section 102 is 40 mm. The first wire-winding section 101 is the main heat-generating area of the heating wire body 10. By increasing the length of the first wire-winding section 101, the phenomenon of local overheating can be effectively reduced, and the quartz heating tube can maintain a uniform temperature distribution.
[0028] Further, the wire diameter of the heating wire body 10 is 0.4 mm. With this setting, while the heating wire body 10 generates more heat, it also has sufficient mechanical strength to prevent the heating wire body 10 from breaking during the stretching process.
[0029] Further, a connection pin 100 is provided at the side end of the second wire-winding section 102 away from the first wire-winding section 101. With this setting, it is convenient to achieve electrical connection with an external power source or a conductive terminal.
[0030] Further, the heating wire body 10 is made of carbon fiber wire. Carbon fiber wire not only has high electrical conductivity but also has high tensile strength. During the winding process, different-sized spiral pitches can be wound and stretched according to actual needs, and it is not easy to break or be damaged, effectively improving the service life of the heating wire body 10.
[0031] Embodiment 2
[0032] As Figure 1 and Figure 2 shown, the embodiment of the present utility model provides a heating wire structure applied to a quartz heating tube, including a heating wire body 10 in a spiral structure. The heating wire body 10 has a first wire-winding section 101 and a second wire-winding section 102. The second wire-winding section 102 is located on both sides of the first wire-winding section 101. The spiral pitch D1 of the first wire-winding section 101 is greater than the spiral pitch D2 of the second wire-winding section 102. In this embodiment, the spiral pitch D1 of the first wire-winding section 101 is 1 mm, and the spiral pitch D2 of the second wire-winding section 102 is 0.6 mm. The spiral pitch D1 of the first wire-winding section 101 is larger, that is, the heat generation density in this area is lower and the generated heat is relatively less. The spiral pitch D2 of the second wire-winding section 102 is smaller, the heat generation density is higher, and more heat is generated. By adjusting the spiral pitch of the heating wire body 10, different amounts of heat can be generated in different areas of the heating tube, so as to achieve the effect of balanced heat distribution, avoid the heat at both ends of the heating wire body 10 being absorbed by the metal components in the heating tube, resulting in local temperature differences, and thus improve the heating uniformity of the quartz heating tube.
[0033] Among them, the length of the first wire winding section 101 is 0.5 of the length of the heating wire body 10, and the length of one of the second wire winding sections 102 is 0.25 of the length of the heating wire body 10. In this embodiment, the length of the first wire winding section 101 is 400 mm, and the length of the second wire winding section 102 is 60 mm. The first wire winding section 101 is the main heating area of the heating wire body 10. By increasing the length of the first wire winding section 101, the phenomenon of local overheating can be effectively reduced, and the quartz heating tube can maintain a uniform temperature distribution.
[0034] Furthermore, the wire diameter of the heating wire body 10 is 0.8 mm. With this setting, while the heating wire body 10 generates more heat, it also has sufficient mechanical strength to prevent the heating wire body 10 from breaking during the stretching process.
[0035] Furthermore, a connection pin 100 is provided at the side end of the second wire winding section 102 away from the first wire winding section 101. With this setting, it is convenient to achieve electrical connection with an external power supply or a conductive terminal.
[0036] Furthermore, the heating wire body 10 is made of a metal wire. In this embodiment, the heating wire body 10 is made of an iron-chromium-aluminum alloy.
[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
