[0002] Infrared radiation heating devices with stainless steel substrates use stainless steel as the supporting substrate and integrate heating elements, such as thick-film resistors and coating materials, on its surface. They convert electrical energy into heat energy using the principle of infrared radiation. Current passes through the heating elements to generate heat. The stainless steel substrate and surface coatings, such as silicon carbide, graphene, and high-entropy oxides, work together to efficiently transfer heat in the form of infrared radiation. Infrared radiation heating devices have numerous advantages and are widely used in industrial manufacturing, daily life, and other fields.

[0003] Infrared radiation heating devices based on stainless steel substrates are used in a variety of complex environments, sometimes in high humidity or acid / alkali environments. These harsh and complex working environments can easily damage the heating devices and shorten their lifespan. In particular, after use, the heating devices are in direct and continuous contact with the environment, which may cause irreversible corrosion to the heating device body and reduce its lifespan.

[0024] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-8 As shown, the infrared radiation heating device based on a stainless steel substrate provided in this embodiment includes a housing 1, protective doors 4, a mounting plate 5, and a pushing component 7. Specifically, the housing 1 has an internal mounting cavity 2 and an opening 3 on one side. The housing 1 has mounting holes 111 for easy installation and fixing, facilitating the overall fixing of the device to a suitable base structure. There are two protective doors 4, each located at the opening 3 of the housing 1. The housing 1 has a switch for synchronously moving the protective doors 4. A heating element 6 is mounted on the side of the mounting plate 5 near the opening 3 of the housing 1. The pushing component 7 is used to adjust the distance between the mounting plate 5 and the opening 3 of the housing 1.

[0026] During use, the heating element 6 can be pushed out of the housing 1 and retracted into the housing 1 by the pusher 7. When the heating element 6 is in use, it can be pushed out to better transfer the heat radiated by the heating element 6 to the environment. When the heating element 6 is not in use, it can be retracted into the housing 1, and the opening 3 of the housing 1 can be sealed by the two protective doors 4 to protect the heating element 6 inside the housing 1. In this process, without affecting the use of the heating element 6, the corrosion and damage of the surrounding environment to the heating element 6 is reduced, and the service life of the heating element 6 is improved.

[0027] Among them, such as Figure 1 , Figure 6 As shown, the switch includes two parallel sliding rails 8 and two sliding blocks 9 sliding within the sliding rails 8; wherein, the two sliding blocks 9 are symmetrically arranged within the sliding rails 8, and the two sliding rails 8 are respectively connected to the top wall and bottom wall of the housing 1; the protective door 4 is a foldable structure or other foldable structure, which is not limited in this application. Regarding the material selection of the protective door 4, it is preferably a high-temperature resistant and corrosion-resistant material, which are all existing technologies and will not be described in detail; if the protective door 4 is a foldable structure, one end of it is fixed to the housing 1. On the side wall, two protective doors 4 are connected to opposite ends of a moving rod 10. The two ends of the moving rod 10 are respectively connected to corresponding sliding blocks 9. By moving the sliding blocks 9 on the sliding track 8, the moving rod 10 can be moved synchronously, thereby moving one end of the protective door 4. When the two symmetrically arranged sliding blocks 9 move towards each other, the protective door 4 can be moved to close the opening 3 of the box 1. When the two symmetrically arranged sliding blocks 9 move away from each other, the protective door 4 can be moved to open the opening 3 of the box 1, so that the box 1 is in a state of internal and external communication.

[0028] To facilitate the opening and closing of the two protective doors 4, the switching device also includes a drive rail 11 located on one side of the sliding rail 8, a drive block 12 symmetrically sliding within the drive rail 11, and a bidirectional threaded rod 13 rotatably connected within the drive rail 11. A motor 14 is installed inside the housing 1, and the output end of the motor 14 is connected to a drive pulley 15. A driven pulley 16 is connected to one end of the bidirectional threaded rod 13, and a transmission belt 17 is fitted onto the drive pulley 15 and the driven pulley 16. The two drive blocks 12 are threadedly connected to both ends of the bidirectional threaded rod 13. The drive blocks 12 are connected to the moving rod 10. The motor 14 drives the bidirectional threaded rod 13 to rotate, causing the two drive blocks 12 threadedly connected to it to move synchronously, thereby driving the moving rod 10 to move, so that the protective doors 4 fold and open, completing the opening and closing of the two protective doors 4.

[0029] Furthermore, the pusher 7 includes two transverse rods 18 symmetrically mounted on the inner walls of both sides of the housing 1. A rack 19 is connected to the transverse rods 18. A shaft bracket 20 corresponding to the transverse rods 18 is connected to the side of the mounting plate 5 away from the opening 3 of the housing 1. A rotating shaft 21 is rotatably connected to the shaft bracket 20. A rotating gear 22 is connected to the rotating shaft 21. The rotating gear 22 meshes with the rack 19. A second motor 23 is mounted on the mounting plate 5. The output end of the second motor 23 is connected to the end of one of the rotating shafts 21. In use, the second motor 23 drives the rotating shaft 21 to rotate, causing the rotating gear 22 to rotate. Since the rack 19 is fixed, the rotating gear 22 drives the mounting plate 5 to move along the extension direction of the rack 19.

[0030] like Figure 4 as well as Figure 5 As shown, the pusher 7 also includes two gear assemblies 25 respectively located on the ends of two rotating shafts 21. A transmission shaft 24 is provided between the two gear assemblies 25, and the transmission shaft 24 is rotatably connected to the mounting plate 5. The gear assembly 25 includes a bevel gear 26 connected to the end of the rotating shaft 21 and a bevel gear 27 connected to the end of the rotating shaft 21, which facilitates the use of a single power source to drive the rotating gears 22 on both sides to rotate. The movement of the mounting plate 5 can be stably driven by the two rotating gears 22. Specifically, the rotating shaft 21 connected to the output end of the second motor 23 drives the gear assembly 25 connected to it to move, that is, the rotating shaft 21 drives the bevel gear 26 to rotate, which in turn drives the bevel gear 27 to rotate. The transmission shaft 24 drives the other gear assembly 25 to run, specifically, the bevel gear 27 drives the bevel gear 26 to rotate, which in turn drives the other rotating gear 22 to rotate. At this time, the two rotating gears 22 rotate synchronously.

[0031] like Figure 7 As shown, two parallel limiting rails 28 are connected to the inner walls on both sides of the housing 1. The mounting plate 5 slides on the limiting rails 28 via the sliding member 29, ensuring the stability of the mounting plate 5 when it moves.

[0032] like Figure 3 As shown, a device box 222 is connected to the mounting plate 5 near the opening 3 of the housing 1, and the heating element 6 is located inside the device box 222.

[0033] like Figure 8As shown, the heating element 6 mentioned above includes a stainless steel substrate 61, an insulating layer 62, an electrode layer 63, an infrared radiation coating 64, and a sealing layer 65. The stainless steel substrate 61 is connected inside the device housing 222. On one side of the stainless steel substrate 61, the insulating layer 62, the electrode layer 63, the infrared radiation coating 64, and the sealing layer 65 are sequentially installed. Preferably, the stainless steel substrate 61 is made of 304 or 316L stainless steel plate, and the surface is sandblasted to form a micron-level roughness to enhance the adhesion of the coating. The insulating layer 62 serves to isolate and insulate the electrode from the stainless steel substrate 61. Silver paste is applied to the insulating layer 62 as the electrode layer 63, preferably through an insulating ceramic sleeve. Fixed and connected to an external power source (existing technology, not shown in the figure); the infrared radiation coating 64 is mainly composed of composite powder of infrared radiation material, silicon carbide, zirconium oxide, and titanium dioxide, with the preferred ratio of the three being 5:3:2. It also preferably includes a binder of silica sol or aluminum phosphate, and auxiliary additives such as graphene and rare earth oxides to enhance thermal conductivity; the sealing layer 65 mainly serves as a protective layer for the above layers. Its working principle is that current flows through the silver paste through the infrared radiation coating 64, and the coating emits infrared rays of a specific wavelength after being heated, achieving efficient thermal energy radiation. At the same time, the good mechanical properties of the stainless steel substrate 61 ensure that the device can work stably for a long time in harsh production environments.

[0034] By configuring the materials and structure described above, the humidity resistance and corrosion resistance of the heating element 6 can be increased, thereby further improving the service life of the heating element 6.

[0035] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
