The regenerated gas and air can generate water when being combusted, high-temperature water vapor can be condensed into water when exchanging heat with the spiral heat exchange tube 3 and the first spiral sheet 21, and as the temperature in the supporting cylinder 2 is higher than the temperature between the supporting cylinder 2 and the annular water tank 4, more condensed water is on the first spiral sheet 21, the downward inclination of one side of the first spiral sheet 21 close to the spiral heat exchange tube 3 is beneficial to the condensed water to drop down on the installation disc 1, and finally the condensed water can be converged on the installation disc 1.

The regenerated gas and air burn and form high-pressure high-temperature gas in the pressurizing cylinder 8, the air flow flowing out of the air outlet port 5 not only carries huge heat but also has high speed, so that the air flow can push the turbofan 12 to rotate, the turbofan 12 rotates to drive the supporting tube 11 to rotate, the supporting tube 11 drives the water absorbing mechanism 17 and the arc-shaped scraping plate 16 to rotate through the mounting frame, the water collecting pipe 23 and the arc-shaped scraping plate 16 are distributed in an obtuse angle shape, and therefore, water on the mounting disc 1 can be collected at the joint of the water collecting pipe 23 and the arc-shaped scraping plate 16 when the water collecting pipe 23 and the arc-shaped scraping plate 16 rotate, namely, the water is collected at the water absorbing port 26.

The principle of the water absorbing mechanism 17 is the same as that of the hand sanitizer pressing principle, when the supporting tube 11 drives the water collecting tube 23 to move to the inclined wedge 13, the hollow ball head 31 is contacted with the inclined wedge 13, along with the rotation of the water collecting tube 23, the hollow ball head 31 moves away from the supporting tube 11 under the action of the inclined wedge 13, the hollow ball head 31 pushes the water conveying tube 28 to move close to the first end cover 24, the water conveying tube 28 drives the limiting ring 34 to move close to the first end cover 24, the spring 29 is extruded, the limiting ring 34 contacts with the piston 36 after a certain distance of movement and pushes the piston 36 to move close to the first end cover 24, the water inlet through groove 32 covered by the piston 36 is exposed when the limiting ring 34 contacts with the piston 36, the distance between the piston 36 and the first end cover 24 is reduced, and water between the piston 36 and the first end cover 24 can enter the water conveying tube 28 through the water inlet through groove 32.

When the hollow ball 31 slides over the wedge 13, the compressed spring 29 pushes the water supply pipe 28 to move away from the first end cover 24 through the cylinder 30, the piston 36 is separated from the limiting ring 34, the cylinder 30 moves a certain distance and then contacts with the piston 36, and pushes the piston 36 to move away from the first end cover 24, at the moment, the piston 36 covers water, at the moment, negative pressure is formed between the first end cover 24 and the piston 36, the steel ball 27 moves towards the direction approaching the water supply pipe 28 to expose the water suction port 26 due to the negative pressure, at the moment, water accumulated in the water suction port 26 is sucked between the first end cover 24 and the piston 36, and at the moment, the negative pressure is recovered to be normal due to the fact that external water enters the water collection pipe 23, at the moment, the spring 29 pushes the ball to block the water suction port 26, and water between the first end cover 24 and the piston 36 cannot flow out.

Because the water is continuously sucked into the water delivery pipe 28, the water is delivered into the evaporation pipe 14 through the hollow ball head 31 and the connecting pipe, the turbofan 12 drives the evaporation pipe 14 to rotate, and the spiral water delivery pipe 28 is fixed, so that the relative rotation of the evaporation pipe 14 and the spiral water delivery rod 15 can still convey the water upwards, the evaporation pipe 14 is directly contacted with high-temperature air flow, when the spiral water delivery rod 15 conveys the water upwards, the water is contacted with the high-temperature evaporation pipe 14 to absorb heat and evaporate to form water vapor, and the water vapor is discharged out of the evaporation pipe 14 upwards.

The support cylinder 2 can increase the time that the air flow stays in the support cylinder 2, thereby increasing the time that the air flow contacts the spiral heat exchange tube 3, and because the opening end of the support cylinder 2 is vertically downward, the air flow can only flow from the lower end of the support cylinder 2 to the annular water tank 4, so that the air flow in the support cylinder 2 will be convected with the air flow coming out of the air outlet hole 9.
