Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating tube technology, and in particular to a heating tube with a fully covered and stable heating layer. Background Technology
[0002] In existing heating element technology, the uniformity and stability of heating have always been difficult problems to solve. The layout of heating elements in traditional heating elements is often unreasonable, leading to uneven heat distribution and affecting heating performance. At the same time, there are also defects in the connection structure and trigger control. For example, improper placement of the thermistors makes it impossible to accurately sense temperature and effectively control the heating process; unreasonable design of short contact points results in poor heat dissipation and may even lead to localized overheating, seriously affecting the service life and safety of the heating element. Therefore, a new type of heating element is needed to solve these problems. Utility Model Content

[0018] Reference Figure 1-4This invention proposes a heating tube with a fully covered and stable heating layer, comprising a heating tube body 1. An insulating layer 2 is uniformly coated on the outer surface of the heating tube body 1. Heating elements 3 and solder pad conductors 5 are disposed on the outer surface of the insulating layer 2 on the heating tube body 1. The heating elements 3 uniformly cover the heating tube body 1 and are electrically connected to a thermistor 6. A thermistor contact 4 corresponding to the thermistor 6 is provided on one side of the solder pad conductor 5. The thermistor contact 4 is located in the middle of the heating tube body 1. When the thermistor 6 triggers heating, the heating elements 3, starting from the thermistor contact 4, cover and heat the heating tube body 1 along its axial direction. The insulating layer 2 has good insulation and thermal conductivity, effectively ensuring the safe operation of the heating tube and assisting in heat conduction. The heating elements 3 and solder pad conductors 5 are disposed on the outer surface of the insulating layer 2, and the heating elements 3 uniformly cover the heating tube body 1, achieving comprehensive heating of the heating tube body 1 and ensuring heating uniformity. The heating element 3 is electrically connected to a thermistor 6. When the temperature changes, the thermistor 6 can detect the change in time and trigger the corresponding heating action. The heating element 3 covers the heating element 1 along the axial direction of the heating element body 1. This unique layout ensures that heat is evenly diffused from the middle of the heating element to both ends, effectively avoiding local overheating or overcooling, and greatly improving the uniformity and stability of heating.
[0019] In this embodiment, the thermistor contact 4 is located in the middle of the heating tube body 1. When there is surrounding resistance to assist heating, the thermistor absorbs heat more quickly and the heat transfer speed is faster.
[0020] Specifically, such as Figure 1 and Figure 2 As shown, the heating element 3 is specifically a heating resistance wire, which is evenly distributed on the heating tube body 1, and has multiple short contact points 31 for heat dissipation. This design effectively enhances heat dissipation, avoids damage to the heating tube due to excessively high local temperatures, and improves the service life and safety of the heating tube.
[0021] Specifically, such as Figure 2-4 As shown, multiple short contact points 31 are arrayed on the outer surface of the heating tube body 1.
[0022] Specifically, positive and negative power contacts are provided on the other side of the pad conductor 5, and the positive and negative power contacts are electrically connected to the power supply.
[0023] Specifically, such as Figure 1-3As shown, the heating element 3 is connected in series with the pad conductor 5. The end of the pad conductor 5 is respectively provided with a neutral wire terminal 51, a first live wire terminal 52, and a second live wire terminal 53. The neutral wire terminal 51, the first live wire terminal 52, and the second live wire terminal 53 are connected with the corresponding neutral wire and live wire to form a heating circuit, ensuring that the heating tube can work normally and achieve a stable heating function.
[0024] Specifically, the insulation layer 2 is a magnesium oxide powder insulating dielectric layer, and the heating resistance wire is a nickel-chromium alloy wire.
[0025] In the specific operation of a heating tube with a fully covered and stable heating layer in this embodiment, when the thermistor 6 triggers heating, the heating element 3 covers and heats the heating tube body 1 along the axial direction of the heating tube body 1, starting from the thermistor contact 4, thereby achieving full heating of the heating tube.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
