[0002] Electric heating tubes are generally made of high-quality imported stainless steel tubes, imported high-temperature magnesium oxide powder, and high-quality heating wires to form the heating element. Other structural parts are made of stainless steel. They have excellent overall performance, ultra-long lifespan, and are easy to maintain. In many fields such as industrial production and daily life, electric heating tubes are commonly used heating equipment, and their performance directly affects heating efficiency and user experience.

[0003] However, electric heating elements are often fixed with screws during installation. This not only makes the installation process cumbersome, requiring tools such as screwdrivers, which is time-consuming and labor-intensive, but also the repeated disassembly and reassembly of screws can easily damage the components, affecting the service life and installation stability of the electric heating element. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapidly heating electric heating tube. This tube is equipped with a guide rod, a sliding plate, and a spring. The electric heating tube is installed and fixed by inserting a limiting block into a limiting groove. In this way, the electric heating tube can be easily and simply installed and removed without the need for external tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric heating element capable of rapid heating includes a mounting plate, a fixing plate below the mounting plate, an electric heating element body mounted on the lower end of the fixing plate, two heat-conducting inner liners inside the electric heating element body, two spiral heating wires installed inside the electric heating element body, the lower ends of the two spiral heating wires being fixed to each other by a bent heating wire, multiple outer cylinders on the outer wall of the electric heating element body, an inner cylinder fixedly connected to the inner wall of each outer cylinder, and a heat sink fixedly connected to the outer wall of each inner cylinder, a mounting block fixedly connected to the upper end of the fixing plate, and a mounting groove for cooperating with the mounting block being opened at the lower end of the mounting plate, with a limit mechanism provided inside the mounting block.

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1-6 An electric heating element capable of rapid heating includes a mounting plate 1, a fixing plate 2 below the mounting plate 1, and an electric heating element body 3 mounted on the lower end of the fixing plate 2. The electric heating element body 3 contains two heat-conducting liners 4 and two spiral heating wires 5. Both heat-conducting liners 4 are made of graphene. Utilizing the ultra-high thermal conductivity of graphene, the heat generated by the spiral heating wires 5 can be rapidly conducted to the surface of the electric heating element body 3. The lower ends of the two spiral heating wires 5 are fixed together by a bent heating wire 6. The bent heating wire 6 and the two spiral heating wires 5... Together, they generate heat, increasing the heating area of ​​the electric heating tube body 3 and further improving the heating speed. During use, the spiral heating wire 5 and the bent heating wire 6 are connected to the external power supply through high-temperature resistant wires. The wires are protected by double insulation, with the inner layer being a high-temperature resistant insulating material and the outer layer being a fire-retardant material to ensure the safety of the electrical connection. Terminals are provided on the electric heating tube body 3, and the high-temperature resistant wires are reliably connected to the spiral heating wire 5 and the bent heating wire 6 through the terminals. The terminals are designed to be waterproof and dustproof to prevent external environmental factors from affecting the stability of the electrical connection.

[0024] The outer wall of the electric heating tube body 3 is provided with multiple outer cylinders 7. Each outer cylinder 7 is fixedly connected to an inner cylinder 8. Each inner cylinder 8 is fixedly connected to a heat sink 9. Each heat sink 9 is annular and made of aluminum alloy with good thermal conductivity to accelerate the dissipation of heat to the outside. Each inner cylinder 8 is sleeved on the electric heating tube body 3. One end of each outer cylinder 7 abuts against one end of the corresponding inner cylinder 8. An annular groove and a locking block structure are provided at the abutment of the outer cylinder 7 and the inner cylinder 8. A locking block is provided at the end of the inner cylinder 8. A corresponding groove is opened on the outer cylinder 7. When installing, the locking block is embedded into the groove to improve the stability of the connection between the outer cylinder 7 and the inner cylinder 8. An installation block 10 is fixedly connected to the upper end of the fixing plate 2. An installation groove 11 that cooperates with the installation block 10 is opened at the lower end of the mounting plate 1. A limiting mechanism is provided in the mounting block 10. The limiting mechanism includes a sliding groove 12 opened inside the mounting block 10.

[0025] In this system, guide rods 13 are fixedly connected between the inner walls of both sides of the slide groove 12. Two sliding plates 14 are slidably connected to the guide rods 13. Both sliding plates 14 are slidably connected to the inner walls of the slide groove 12. The two sliding plates 14 are elastically connected by two springs 15. Limiting blocks 16 are fixedly connected to the opposite sides of the two sliding plates 14. The opposite ends of the two limiting blocks 16 penetrate the mounting block 10. Limiting grooves 17 that mate with the corresponding limiting blocks 16 are opened on the inner walls of both sides of the mounting groove 11. Connecting plates 18 are fixedly connected to the opposite sides of the two sliding plates 14. Both sides of the connecting plates 18 penetrate the mounting block 10 and extend to the outside. Both connecting plates 18 are provided with a protective layer. Both protective layers are made of rubber. The protective layer can prevent the connecting plates 18 from being worn during frequent operation, and at the same time avoid accidental electric shock to the operator, thus improving the safety of use. When the connecting plate 18 is pressed, the sliding plate 14 compresses the spring 15, and the limiting block 16 retracts into the mounting block 10. After the mounting block 10 is inserted into the mounting groove 11, the connecting plate 18 is released, and the spring 15 returns to its original position, pushing the limiting block 16 into the limiting groove 17. The installation can be completed without the need for screws.

[0026] In this invention, when the electric heating tube body 3 is connected to an external power source, the current is transmitted to the spiral heating wire 5 and the bent heating wire 6 through a high-temperature resistant wire. The current will generate heat. Since both heat-conducting liners 4 are made of graphene, they can quickly conduct the heat generated by the spiral heating wire 5 and the bent heating wire 6 to the surface of the electric heating tube body 3. At the same time, the spiral heating wire 5 and the bent heating wire 6 form a three-dimensional heating structure, which increases the heating area and thus achieves rapid heating.

[0027] When heat is generated on the surface of the electric heating tube body 3, it will be transferred to the inner cylinder 8 through heat conduction. At this time, the heat sink 9 will absorb the heat. The heat sink 9 is arranged at a certain interval to ensure smooth airflow between the heat sink 9. The heat is dissipated to the external environment through air convection. The outer cylinder 7 and the inner cylinder 8 are tightly connected by an annular groove and a locking block structure to ensure the stable operation of the heat dissipation channel.

[0028] When the electric heating element body 3 needs to be installed, press the connecting plate 18. The connecting plate 18 drives the sliding plate 14 to slide on the guide rod 13. At this time, the spring 15 is in a compressed state, causing the limiting block 16 to retract into the mounting block 10. Without releasing the spring, align the mounting block 10 with the mounting groove 11 of the mounting plate 1 and insert it. Then, release the connecting plate 18, the spring 15 returns to its original position, and pushes the sliding plate 14 and the limiting block 16 outward. The limiting block 16 is engaged in the limiting groove 17, thus quickly fixing the mounting block 10 to the mounting groove 11. With this installation method, there is no need to use screwdrivers or other tools to tighten screws. Installation can be completed with simple pressing, inserting and releasing operations, which shortens the installation time.

[0029] 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.
