Description

Technical Field

[0001] This utility model relates to the field of thick film heating tube technology, specifically a stainless steel thick film heating tube. Background Technology

[0002] Stainless steel thick-film heating elements are high-performance heating elements with rapid heating rates of 80-150℃ / second, high thermal efficiency (typically ≥97%), long service life (generally ≥6000 hours), high power density, compact size (power density can reach 40-100w / cm²), multiple insulation design for strong safety protection, and use of food-grade stainless steel (such as 304 stainless steel), making them healthy and environmentally friendly. Due to their high power density, rapid heating, and high thermal efficiency, stainless steel thick-film heating elements are widely used in household appliances such as water purifiers, dishwashers, steam ovens, and coffee machines, as well as in industrial circulating water heating and automotive fields.

[0003] However, the existing stainless steel thick film heating tubes have poor overall applicability because the threaded tube and the stainless steel tube are welded together as one piece. This is because the threaded tube cannot be adjusted or replaced according to the needs during use. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel thick film heating tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stainless steel thick film heating tube includes a threaded cylinder, an assembly mechanism at the bottom of the threaded cylinder, a connecting steel cylinder, external threads on the outer side of the connecting steel cylinder, a limit plate fixedly installed at the top of the connecting steel cylinder, a threaded cylinder fixedly installed at the top of the limit plate, and a tube body mechanism at the bottom of the limit plate.

[0007] Preferably, the assembly mechanism further includes a connecting plate, which is fixedly installed on both sides of the limiting plate away from the threaded cylinder, and the connecting plate is provided with connecting holes.

[0008] Preferably, the tube body structure includes a steel heating tube, a limiting plate is fixedly installed at the top end of the steel heating tube, and a large sealing gasket is fixedly installed between the steel heating tube and the limiting plate.

[0009] Preferably, a limiting block is fixedly installed inside the steel heating tube, a connecting steel cylinder is fixedly installed on the limiting block, and a small sealing gasket is fixedly installed between the limiting block and the connecting steel cylinder.

[0010] Preferably, the steel heating tube has an internal thread on the side near the limiting block, and an external thread is fixedly installed on the outside of the internal thread.

[0011] Preferably, a thick film heating material is fixedly installed on the outside of the steel heating tube, and a welding plate is fixedly installed on the thick film heating material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This stainless steel thick film heating tube allows the connecting steel cylinder and threaded cylinder to be disassembled through screwing, and different threaded cylinders can be replaced after disassembly, thus making the overall applicability higher.

[0014] 2. This stainless steel thick film heating tube has a separable tube body structure from the assembly structure, so it does not need to be replaced as a whole when any structure is damaged, thus reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 As shown, this utility model provides a technical solution:

[0021] A stainless steel thick film heating tube includes a threaded cylinder 101. An assembly mechanism 102 is provided at the bottom end of the threaded cylinder 101. The assembly mechanism 102 includes a connecting steel cylinder 103. An external thread 104 is provided on the outer side of the connecting steel cylinder 103. A limiting plate 105 is fixedly installed at the top end of the connecting steel cylinder 103. The threaded cylinder 101 is fixedly installed at the top end of the limiting plate 105. A tube body mechanism 106 is provided at the bottom end of the limiting plate 105.

[0022] The above solution allows the entire assembly to be connected to the water pipe via a threaded cylinder, enables the external threaded steel cylinder to be installed by screwing, and provides a limiting plate for positioning.

[0023] In this embodiment, preferably, the assembly mechanism 102 further includes a connecting plate 201, which is fixedly installed on the limiting plate 105 on both sides away from the threaded cylinder 101, and the connecting plate 201 is provided with connecting holes 202.

[0024] The above solution allows the connecting plates to be connected and fixed through the connecting holes, thereby securing the entire assembly.

[0025] In this embodiment, preferably, the tube body mechanism 106 includes a steel heating tube 203, a limiting plate 105 is fixedly installed at the top end of the steel heating tube 203, and a large sealing gasket 204 is fixedly installed between the steel heating tube 203 and the limiting plate 105.

[0026] The above method allows for sealing between the steel heating pipe and the limiting plate using a large sealing gasket.

[0027] In this embodiment, preferably, a limiting block 205 is fixedly installed inside the steel heating tube 203, a connecting steel cylinder 103 is fixedly installed on the limiting block 205, and a small sealing gasket 206 is fixedly installed between the limiting block 205 and the connecting steel cylinder 103.

[0028] The above scheme allows for the limiting of the connecting steel cylinder by using a limiting block, and the small sealing gasket allows for sealing between the connecting steel cylinder and the limiting block.

[0029] In this embodiment, preferably, the steel heating tube 203 has an internal thread 301 on the side near the limiting block 205, and an external thread 104 is fixedly installed on the outside of the internal thread 301.

[0030] The above solution allows for the connection of internal and external threads, enabling the connecting steel cylinder to be disassembled and reassembled via screwing, thus allowing the connecting steel cylinder to be replaced along with the threaded cylinder.

[0031] In this embodiment, preferably, a thick film heating material 302 is fixedly installed on the outside of the steel heating tube 203, and a welding piece 303 is fixedly installed on the thick film heating material 302.

[0032] The above scheme allows the steel heating tube to be heated using a thick-film heating material, and the electrode tabs can be welded using welding plates to connect the wires.

[0033] In this embodiment, a stainless steel thick-film heating tube is used by the user to weld the tabs using welding piece 303 and then connect the tabs to the wires. Subsequently, the external thread 104 and internal thread 301 are connected to assemble the connecting steel cylinder 103 and the steel heating tube 203. During assembly, the small sealing gasket 206 is clamped by the limiting block 205, and simultaneously, the limiting plate 105 and the steel heating tube 203 are in contact, clamping the large sealing gasket 204. The large sealing gasket 204, in conjunction with the small sealing gasket 206, ensures that the connecting steel cylinder 103 will not leak after assembly. Therefore, the user can then use the threaded cylinder... 101 connects and traverses the water flow pipeline, and fixes the connecting plate 201 and the limiting plate 105 through the connecting hole 202. After fixing, the thick film heating material 302 is heated by the wire and heated to heat the water flow inside the steel heating pipe 203. When the threaded cylinder 101 needs to be adjusted, the user can remove the connecting steel cylinder 103 and the threaded cylinder 101 by screwing. After removal, different threaded cylinders 101 can be replaced. Since the pipe structure and the assembly structure can be separated, it is not necessary to replace the whole structure when any structure is damaged, which reduces the maintenance cost.
