Its core structure consists of a metal tube as the outer shell, with an alloy heating wire encapsulated inside as the heating element. The space between the heating wire and the metal tube is filled with a dense insulating medium such as magnesium oxide powder to fix the heating element and block current leakage. Lead rods are provided at both ends as conductive connectors to allow the element to form a circuit with the power supply. It generates heat by passing electricity through the heating element, which is conducted to the metal shell through the insulating medium, and then heats the target medium such as air, water, and oil. It is widely used in household appliances, industrial heating equipment and other scenarios.

[0003] The pins of existing electric heating elements are mostly directly exposed to the external environment or simply connected by terminals, lacking a targeted protective structure, making them extremely prone to damage. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example 1, byFigure 1 The present invention relates to an electric heating tube with multiple protections, comprising a tube body 1, a mounting base 4 fixedly connected to the top end of the tube body 1, pins 3 provided on the mounting base 4, and a protective mechanism 2 provided on the top of the mounting base 4.

[0017] Specifically, by Figure 2 The protective mechanism 2 includes a protective cylinder 201 located on top of the mounting base 4. A handle 2013 is fixedly connected to the top of the protective cylinder 201, and a sealing ring 202 is fixedly connected to the bottom of the protective cylinder 201. The sealing ring 202 fits against the top of the mounting base 4, ensuring the airtightness between the protective cylinder 201 and the mounting base 4. A support shaft 204 is rotatably connected to the top of the mounting base 4. A U-shaped round rod 2010 is fixedly connected to the top of the support shaft 204. A lifting plate 208 is movably sleeved on the outside of the U-shaped round rod 2010. The lifting plate 208 is fixed to the outside of the protective cylinder 201. Two springs 207 are symmetrically fixedly connected between the lifting plate 208 and the support shaft 204. Both springs 207 are sleeved on the outside of the U-shaped round rod 2010, facilitating the longitudinal movement and rotation of the protective cylinder 201. The top of the mounting base 4 is fixedly connected to a first upright plate 2011 and a second upright plate 205. The outer sides of the first upright plate 2011 and the second upright plate 205 are respectively fixedly connected to abutting posts 2012 and 209. The lifting plate 208 abuts against the first abutting post 2012. The outer sides of the first upright plate 2011 and the second upright plate 205 are respectively fixedly connected to a first limiting rod 203 and a second limiting rod 206. The lifting plate 208 is sleeved on the outer side of the first limiting rod 203. When the lifting plate 208 abuts against the first abutting post 2012 and descends, it is convenient for the lifting plate 208 to be sleeved on the outer side of the first limiting rod 203, so that the protective cylinder 201 can be removed from the outer side of the pin 3. When the lifting plate 208 abuts against the second abutting post 209 and descends, it is convenient for the lifting plate 208 to be sleeved on the outer side of the second limiting rod 206, so that the protective cylinder 201 can cover the pin 3. In use, first pull the handle 2013 upwards, causing the protective cylinder 201 to move upwards and the lifting plate 208 to slide upwards along the U-shaped rod 2010. At this time, both springs 207 are stretched until the lifting plate 208 disengages from the outside of the first limiting rod 203. Then, rotate the protective cylinder 201, causing the lifting plate 208 and the support shaft 204 to rotate until the lifting plate 208 abuts against the second abutment post 209. At this time, the protective cylinder 201 is directly above the pin 3. Then, release the handle 2013. At this time, both springs 207 reset and cause the lifting plate 208 to slide downwards along the U-shaped rod 2010, so that the lifting plate 208 is fitted onto the outside of the second limiting rod 206. At the same time, the protective cylinder 201 descends until the sealing ring 202 fits against the mounting base 4, sealing and protecting the pin 3 and preventing damage to the pin 3.

[0018] Specifically, by Figure 3The tube body 1 includes a quartz tube 101 fixed to the bottom of the mounting base 4. A heating wire 102 is provided on the inner side of the quartz tube 101, and the pin 3 is connected to the heating wire 102. A metal tube 105 is provided on the outer side of the quartz tube 101. An insulating layer 104 is filled between the metal tube 105 and the quartz tube 101. The insulating layer 104 and the metal tube 105 form double insulation to enhance the prevention of leakage. A metal isolation cover 103 is provided on the outer side of the metal tube 105. By setting the metal isolation cover 103, it is prevented that fragments or liquids will leak out after breakage. The insulating layer 104 is made of magnesium sand.
