Description of reference numerals: the electric heating tube comprises an electric heating tube 1, a leading-out rod 1-1, a tube body 1-2, magnesium oxide powder 1-3, a resistance wire 1-4, a spiral water tube 2, a spiral groove 2-1, a water tube body 2-2, a water tube body A2-3, a water tube body B2-4, a water inlet tube 3 and a water outlet tube 4.
Detailed Description
The utility model will be described in detail below with reference to the following drawings:
example 1: as shown in figures 2-6, the spiral water inlet electric heating pipe structure mainly comprises an electric heating pipe 1 and a spiral water pipe 2, wherein the electric heating pipe 1 comprises a leading-out rod 1-1, a pipe body 1-2, magnesium oxide powder 1-3 and a resistance wire 1-4, the spiral water pipe 2 mainly comprises a cylindrical water pipe body 2-2, and the water pipe body 2-2 is of an integrally formed structure and is manufactured by adopting methods such as water expansion forming and 3D printing. The inner wall of the water pipe body 2-2 is provided with a spiral groove 2-1, and two ends of the water pipe body 2-2 are respectively communicated with a water inlet pipe 3 and a water outlet pipe 4; the water pipe body 2-2 is sleeved on the pipe body 1-2, the surface of the pipe body 1-2 is provided with an anti-scaling coating, and water in the spiral groove 2-1 is directly contacted with the surface of the pipe body 1-2.
The spiral water pipe 2 is assembled with the electric heating pipe 1 in an integral structure, and is in clearance fit, so that the problem that the electric heating pipe generates heat and expands when heating is avoided, and the spiral water pipe needs to be in interference fit is solved. The spiral water pipe 2 can be integrally structured, a temperature controller and a fuse isothermal control device can be arranged on the water pipe body 2-2, and a temperature control device can be arranged in the electrothermal pipe 1, so that the installation of the temperature control device on the water pipe is simpler. Water enters the spiral groove 2-1 from the water inlet pipe 3, heat is transferred to the spiral water pipe 2 through the electric heating pipe 1, the integrated structure heats water, the temperature control device controls temperature in a dry heating mode, and water is discharged from the water outlet pipe 4.
Example 2: as shown in fig. 7 to 8, the difference from embodiment 1 is that: the water pipe body 2-2 comprises a water pipe body A2-3 and a water pipe body B2-4, wherein the water pipe body A2-3 and the water pipe body B2-4 are provided with half spiral grooves, and the water pipe body A2-3 and the water pipe body B2-4 are spliced together through welding to form the spiral groove 2-1.
