Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in figure 1, the thick/thin film heating tube type electric water heating device comprises a thick/thin film heating tube 1, an inner seat 2, an upper fixed seat plate 3, a lower fixed seat plate 4 and a shell 5,

the inner housing 2 includes a body 21 having upper and lower openings, a flange 22 provided at a lower end of the body, and a spiral plate 23 surrounding the body at an upper portion of the flange,

the upper fixing seat plate 3 comprises an upper fixing hole arranged in the center and an upper interface 31 surrounding the upper fixing hole, and the lower fixing seat plate 4 comprises a lower fixing hole arranged in the center and a lower interface 41 surrounding the upper fixing hole;

the shell 5 is provided with a lower opening, a top plate of the shell 5 is provided with a central hole 51 and a water outlet interface tube 52 which are positioned on the axis, the shell is also provided with a water inlet tube 53 which is integrally formed with the shell, and the lower end of the water inlet tube 53 is communicated with the lower end of the shell 5;

the inner seat 2 is inserted into the shell 5, the upper end of the tube body part 51 is embedded with the central hole 51, the flange 22 is embedded with the lower end of the shell 5 and is in liquid seal, the spiral plate 23 is attached to the inner wall of the shell 5 to form a spiral water channel, the lower end of the spiral water channel is communicated with the water inlet tube 52, the upper end of the spiral water channel is communicated with the water outlet interface tube 52, and the water outlet interface tube 52 is communicated with the thick/thin film heating tube 1; the thick/thin heating tube 1 extends out from two ends of the tube body part 21, the upper interface 31 of the upper fixing seat plate 3 is inserted into the upper end of the tube body part 21, the lower interface 41 of the lower fixing seat plate 4 is inserted into the lower end of the tube body part 21, and the thick/thin heating tube 1 is fixed with the upper fixing hole and the lower fixing hole; the gap between the thick/thin film heating tube 1 and the tube body 21 between the upper fixing seat plate 3 and the lower fixing seat plate 4 forms a heat radiation and heat conduction cavity.
