Description

Technical Field

[0001] This utility model relates to the field of electric heating coil technology, and in particular to an energy-saving electric heating coil. Background Technology

[0002] Electric heating coils, as important components commonly used in heating applications, are widely used in industrial processing, home heating, and electric heating equipment. Traditional electric heating coils generally use resistive materials such as nickel-chromium wire as heating elements, combined with a casing structure to achieve heat concentration and conduction. However, in practical applications, existing technologies still have the following significant shortcomings:

[0003] Firstly, most existing electric heating coils adopt a simple enclosed structure with a housing, lacking an effective heat reflection mechanism inside. This results in most of the heat generated by the heating element being passively dissipated, leading to low heat utilization efficiency, which does not conform to the current technological development trend of energy conservation and emission reduction.

[0004] Secondly, the heating wire in the heating coil is usually encapsulated in a glass tube to improve stability and safety. However, during use, the surface of the glass tube is prone to adsorbing dust, particulate matter and other impurities, especially in dusty environments. Although these deposits do not directly affect the heating element, they can hinder the normal transfer of heat radiation, indirectly reduce heating efficiency, and may lead to increased energy consumption.

[0005] Furthermore, we disclose an energy-saving electric heating coil to meet the practical needs of existing technologies, such as low heat energy reflection utilization and difficulty in cleaning dust accumulation on internal components. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose an energy-saving electric heating coil to solve the problems of low heat energy reflection utilization and difficulty in cleaning dust accumulation in internal components in the existing technology.

[0007] To achieve the above objectives, this utility model provides an energy-saving electric heating coil, comprising an upper cover and a lower cover, which are rotatably connected to each other via a rotating shaft mounted on one side. Multiple nickel-chromium wires are arranged inside both the upper and lower covers, and glass tubes are sleeved around the nickel-chromium wires. A reflective layer is provided on the inner wall of both the upper and lower covers. A dust-cleaning assembly is provided inside both the upper and lower covers for cleaning dust from the surface of the internal glass tubes.

[0008] Preferably, both ends of the outer wall of the upper cover and the lower cover are fixedly connected to fixing blocks, and locking bolts are provided in the two fixing blocks on the same side.

[0009] Preferably, the nickel-chromium wires are spaced evenly inside the upper and lower covers, and the reflective layer is made of aluminum foil.

[0010] Preferably, the dust removal assembly includes two fixing plates, both of which are semi-circular and respectively disposed in the upper cover and the lower cover. Multiple glass tubes inside the upper cover and the lower cover are respectively fixedly connected to the fixing plates on the same side.

[0011] Preferably, a connecting block is fixedly connected to one side of the outer wall of each of the two fixed disks. The two connecting blocks are slidably connected inside the upper cover and the lower cover, respectively. A cam is provided on one side of each of the two connecting blocks. The outer wall of each of the two cams is in contact with one side end face of each of the two connecting blocks. A miniature high-frequency motor is installed at the lower end of each of the two cams. The two miniature high-frequency motors are respectively located inside the upper cover and the lower cover.

[0012] Preferably, a return spring is fixedly connected to the end face of each of the two connecting blocks away from the cam, and the end of each of the two return springs away from the connecting block is fixedly connected to the upper cover and the lower cover, respectively.

[0013] Preferably, both ends of the glass tube are fixedly connected to connecting plates, one end of each connecting plate is fixedly connected to a buffer spring at even intervals, both ends of the upper cover and the lower cover are fixedly connected to baffles, and the end of the buffer spring away from the connecting plate is fixedly connected to the baffle.

[0014] The beneficial effects of this utility model are:

[0015] 1. This energy-saving electric heating coil forms a closed or semi-closed heat reflection space structure by setting a reflective layer made of aluminum foil on the inner walls of both the upper and lower covers. This effectively reflects the heat radiation energy released by the nickel-chromium wire back into the cover, thereby preventing heat from being directly lost to the outside and improving the utilization efficiency of heat energy. As a high reflectivity material, aluminum foil has a strong ability to reflect infrared heat radiation, which can significantly enhance the heat accumulation effect inside the cover, so that the heat released by the nickel-chromium wire during operation can be fully utilized. On this basis, the nickel-chromium wire is arranged at a uniform spacing inside the cover to further ensure that the entire heating space is heated evenly, avoiding local overheating or heat waste, and reducing the overall working energy consumption of the electric heating coil.

[0016] 2. This energy-saving electric heating coil is equipped with a dust removal component. This component includes multiple cooperating structural units such as a fixed plate, a connecting block, a cam, a micro high-frequency motor, and a return spring. During operation, the micro high-frequency motor drives the cam to rotate, thereby pushing the connecting block in contact with it to reciprocate and slide. This causes the semi-annular fixed plate, which is fixedly connected to the connecting block, to drive the connected glass tube to generate slight mechanical vibration. This vibration is sufficient to dislodge dust particles adhering to the outer surface of the glass tube, realizing the function of automatically cleaning the surface of the glass tube without disassembly. Through periodic automatic dust removal, the surface of the glass tube can be kept clean, avoiding dust accumulation that would hinder heat radiation, thus ensuring that the heat transfer efficiency is not affected and that the device still has stable and efficient heating performance during long-term operation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 4 As shown, an energy-saving electric heating coil includes an upper cover 1 and a lower cover 2, which are rotatably connected to each other by a rotating shaft installed on one side. Multiple nickel-chromium wires 7 are provided inside the upper cover 1 and the lower cover 2. Glass tubes 8 are sleeved on the outside of the nickel-chromium wires 7. Reflective layers 9 are provided on the inner walls of the upper cover 1 and the lower cover 2. Dust removal components are provided inside the upper cover 1 and the lower cover 2. The dust removal components are used to clean the dust on the surface of the internal glass tubes 8.

[0027] This device is a reasonably structured, energy-efficient electric heating coil. It mainly consists of an upper cover 1, a fixing block 3, and a lower cover 2 forming a closed or semi-closed heating structure. The interior is uniformly equipped with nickel-chromium wires 7 covering glass tubes 8 as heating elements. The inner wall of the cover is provided with a high-reflectivity aluminum foil reflective layer 9 to improve the heat energy utilization rate. The device is also equipped with a dust removal component. The cam 13 mechanism driven by a micro high-frequency motor 14 drives the fixing plate 10 of the fixed glass tube 8 to vibrate, thereby periodically removing dust from the surface of the glass tube 8. At the same time, the buffer and reset structures at both ends improve the overall stability and durability of the device, making it suitable for various occasions that require a high-efficiency heat source.

[0028] Furthermore, such as Figure 1 As shown, both ends of the outer wall of the upper cover 1 and the lower cover 2 are fixedly connected to a fixing block 3, and a locking bolt 4 is provided in each of the two fixing blocks 3 on the same side.

[0029] Both ends of the outer wall of the upper cover 1 and the lower cover 2 are fixedly connected to fixing blocks 3, and locking bolts 4 are provided in the two fixing blocks 3 on the same side. The design of this structure is mainly used to realize the closing and locking function and structural stability of the entire device during use. By setting the lower cover 2 at both ends of the upper cover 1 and the fixing blocks 3, and cooperating with the locking bolts 4 to fix it mechanically, a reliable clamping force can be provided after the cover is closed, preventing the cover from loosening or shifting due to thermal expansion and contraction or external vibration during the heating process. This ensures that the heating structure of the internal nickel-chromium wire 7 and glass tube 8 is always in a stable and sealed working state. This structure not only improves the overall strength and durability of the device, but also facilitates users to quickly disassemble and maintain it, improving the practicality and convenience of the equipment while ensuring safety.

[0030] Furthermore, such as Figure 2 As shown, the nickel-chromium wire 7 maintains a uniform spacing inside the upper cover 1 and the lower cover 2, and the reflective layer 9 is made of aluminum foil material;

[0031] The nickel-chromium wires 7 are spaced evenly inside the upper cover 1 and the lower cover 2, and the reflective layer 9 is made of aluminum foil. This structural design aims to achieve the goals of heating uniformity and efficient utilization of thermal energy. By evenly distributing the nickel-chromium wires 7 inside the cover, the heat distribution of each heating element can be consistent during operation, avoiding local overheating or heating blind spots, and improving the stability of the overall heating effect. At the same time, the aluminum foil reflective layer 9 set on the inner wall of the cover has good infrared reflection performance, which can reflect the heat radiation released by the nickel-chromium wires 7 back to the internal space, effectively reducing heat loss to the outside and enhancing the heat energy accumulation effect. This structure not only improves heating efficiency and reduces energy consumption, but also helps the device achieve the technical effects of energy saving and rapid heating.

[0032] Furthermore, such as Figures 1 to 4As shown, the dust removal assembly includes two fixed disks 10, both of which are semi-circular and respectively disposed within the upper cover 1 and the lower cover 2. Multiple glass tubes 8 inside the upper cover 1 and the lower cover 2 are fixedly connected to the fixed disks 10 on the same side. Connecting blocks 15 are fixedly connected to one side of the outer wall of each of the two fixed disks 10. The two connecting blocks 15 are slidably connected inside the upper cover 1 and the lower cover 2. A cam 13 is provided on one side of each connecting block 15, and the outer wall of each cam 13 contacts one end face of each connecting block 15. The lower ends of each cam 13 are mounted with… There are two miniature high-frequency motors 14, which are respectively installed inside the upper cover 1 and the lower cover 2. The two connecting blocks 15 are fixedly connected to the end face away from the cam 13. The two return springs 6 are fixedly connected to the upper cover 1 and the lower cover 2 respectively. The two ends of the glass tube 8 are fixedly connected to the connecting plate 11. The end of the connecting plate 11 is fixedly connected to the buffer spring 12 at even intervals. The two ends of the upper cover 1 and the lower cover 2 are fixedly connected to the baffle 5. The end of the buffer spring 12 away from the connecting plate 11 is fixedly connected to the baffle 5.

[0033] This structure achieves automatic dust cleaning of the glass tubes 8 by setting up a dust removal assembly consisting of a fixed disk 10, a connecting block 15, a cam 13, a miniature high-frequency motor 14, and a return spring 6. Specifically, multiple glass tubes 8 are fixedly connected to the semi-circular fixed disk 10. The fixed disk 10 is slidably installed inside the cover via the connecting block 15 and is driven to slide by the cam 13 on one side. The cam 13 is linked with the miniature high-frequency motor 14, and through periodic rotation, it drives the connecting block 15 to reciprocate or oscillate slightly, thereby causing the glass tubes 8 fixed on it to vibrate mechanically and shake off. The dust and impurities adhering to its surface are removed. The end of the connecting block 15 away from the cam 13 is connected to a return spring 6, which can quickly restore it to its initial position after the dust removal is completed, ensuring structural stability and accurate positioning. At the same time, the two ends of the glass tube 8 are connected to the buffer spring 12 through the connecting plate 11. The spring is fixed to the baffle 5 at both ends of the cover, thus playing a buffering and protective role during vibration, preventing the glass tube 8 from being damaged by resonance. This structure uses mechanical vibration to achieve automatic dust removal without disassembly, which not only effectively improves heating efficiency and heat radiation effect, but also significantly reduces the frequency of manual maintenance, enhancing the energy efficiency and ease of use of the device.
