The other end of the exhaust pipe 3 can be connected to the inside of the heat exchange box 2. The waste gas generated during the use of the tank body 1 is discharged through the exhaust pipe 3 and enters the inside of the heat exchange box 2. The heat exchange box 2 can recycle the heat in the waste gas for reuse.
[0027] like Figure 1-Figure 4 As shown, a first connecting assembly is provided between the heat exchange box 2 and the exhaust pipe 3, and the first connecting assembly consists of a threaded tube 4, a top tube 5, a through groove 6, a lifting plate 7, a first cover plate 8, a lifting rod 9, a first spring 10 and a threaded groove 11. The end of the exhaust pipe 3 away from the tank body 1 is connected with the threaded tube 4, and the other end of the threaded tube 4 is connected with the top tube 5.

[0028] Specifically, when connecting the heat exchange box 2 and the exhaust pipe 3, the top pipe 5 is inserted into the thread groove 11 and moved upward along the thread groove 11 until the top surface of the top pipe 5 contacts the first cover plate 8. At this time, the outer side of the threaded pipe 4 just contacts the thread groove 11. The threaded pipe 4 is rotated to drive the threaded pipe 4 to move upward along the thread groove 11. The movement of the threaded pipe 4 drives the top pipe 5 to move upward. The movement of the top pipe 5 pushes the first cover plate 8 upward. The movement of the first cover plate 8 drives the lifting plate 7 and the lifting rod 9 to move upward. The first spring 10 is stretched until the top pipe 5 completely enters the heat exchange box 2 and the lifting rod 9 During the movement, the slide groove is never separated, and the exhaust gas inside the exhaust pipe 3 enters the heat exchange box 2 through the threaded pipe 4, the top pipe 5 and the through groove 6. The width of the lifting rod 9 is much smaller than the through groove 6, and the lifting rod 9 has a small blocking range of the through groove 6. When the exhaust pipe 3 is disassembled, the threaded pipe 4 is rotated in the reverse direction to drive the threaded pipe 4 to move downward, and the first spring 10 pulls the first cover plate 8 to move downward until the threaded pipe 4 is separated from the thread groove 11. The exhaust pipe 3 can be disassembled, and the first cover plate 8 covers the thread groove 11, thereby preventing the exhaust gas in the heat exchange box 2 from being discharged to the outside and reducing heat loss.

The bottom surface of the heat exchange box 2 is fixedly provided with a push rod 16 and a retaining cylinder 19 adapted to the groove 17. The plug plate 14 is slidably connected to the U-shaped plate 12 through the groove 17, the top rod 16 penetrates the U-shaped plate 12 and is slidably connected to the U-shaped plate 12, and the second connecting component can facilitate the connection and disassembly of the tank body 1 and the heat exchange box 2. A bolt 13 is arranged on the top of the tank body 1, and the bolt 13 penetrates the U-shaped plate 12 and is threadedly connected to the U-shaped plate 12. A threaded hole 15 is arranged on the outside of the plug plate 14 that penetrates to the inside, and the bolt 13 is threadedly connected to the plug plate 14 through the threaded hole 15. The bolt 13 is threadedly connected to the U-shaped plate 12 and the plug plate 14 respectively, which can improve the limiting effect of the tank body 1 on the heat exchange box 2.
[0030] Specifically, when connecting the tank body 1 and the heat exchange box 2, align the plug plate 14 with the groove 17 and move the heat exchange box 2 downward until the plug plate 14 is engaged in the groove 17. At this time, the bottom surface of the heat exchange box 2 is close to the bottom surface of the U-shaped plate 12, so that the heat exchange box 2 is installed above the tank body 1. The heat exchange box 2 moves downward to drive the push rod 16 to move downward. The push rod 16 moves and contacts the second cover plate 20 to drive the second cover plate 20 to move downward. The second spring 18 is extended, and the second cover plate 20 moves to drive the retaining cylinder 19 to move downward. During the downward movement of the retaining cylinder 19, it never separates from the tank body 1. The second cover plate 20 cooperates with the retaining cylinder 19 to cover the top of the tank body 1. Turn the screw The grooved holes 15 make the threaded holes 15 threadedly connected with the U-shaped plate 12 and the plug plate 14 respectively, so as to fix the position of the heat exchange box 2 relative to the tank body 1 and improve the limiting effect of the tank body 1 on the heat exchange box 2. When disassembling the heat exchange box 2, the threaded holes 15 are rotated in the opposite direction to make the threaded holes 15 disengage from the plug plate 14, and the heat exchange box 2 is moved upward to drive the plug plate 14 and the top rod 16 to move upward.

[0031] Specific working principle:
[0032] When the device connects the heat exchange box 2 and the exhaust pipe 3, the jacking pipe 5 is inserted into the thread groove 11 and moved upward along the thread groove 11 until the top surface of the jacking pipe 5 contacts the first cover plate 8. At this time, the outer side of the threaded pipe 4 just contacts the thread groove 11. The threaded pipe 4 is rotated to drive the threaded pipe 4 to move upward along the thread groove 11. The movement of the threaded pipe 4 drives the jacking pipe 5 to move upward. The movement of the jacking pipe 5 pushes the first cover plate 8 upward. The movement of the first cover plate 8 drives the lifting plate 7 and the lifting rod 9 to move upward. The first spring 10 is stretched until the jacking pipe 5 completely enters the heat exchange box 2 and the lifting rod 9 During the movement, the slide groove is never separated, and the exhaust gas inside the exhaust pipe 3 enters the heat exchange box 2 through the threaded pipe 4, the top pipe 5 and the through groove 6. The width of the lifting rod 9 is much smaller than the through groove 6, and the lifting rod 9 has a small blocking range of the through groove 6. When the exhaust pipe 3 is disassembled, the threaded pipe 4 is rotated in the reverse direction to drive the threaded pipe 4 to move downward, and the first spring 10 pulls the first cover plate 8 to move downward until the threaded pipe 4 is separated from the thread groove 11. The exhaust pipe 3 can be disassembled, and the first cover plate 8 covers the thread groove 11, thereby preventing the exhaust gas in the heat exchange box 2 from being discharged to the outside and reducing heat loss.
[0033] When the device connects the tank body 1 and the heat exchange box 2, the plug plate 14 is aligned with the groove 17 and the heat exchange box 2 is moved downward until the plug plate 14 is engaged in the groove 17. At this time, the bottom surface of the heat exchange box 2 is close to the bottom surface of the U-shaped plate 12, so that the heat exchange box 2 is installed above the tank body 1. The heat exchange box 2 moves downward to drive the push rod 16 to move downward. The push rod 16 moves and contacts the second cover plate 20 to drive the second cover plate 20 to move downward. The second spring 18 is extended, and the second cover plate 20 moves to drive the retaining cylinder 19 to move downward. During the downward movement of the retaining cylinder 19, it never leaves the tank body 1. The second cover plate 20 cooperates with the retaining cylinder 19 to cover the top of the tank body 1, and the threaded hole 15 is rotated to make the threaded hole 15 respectively aligned with the U-shaped plate 12 and the plug plate The plate 14 is threadedly connected to fix the position of the heat exchange box 2 relative to the tank body 1, thereby improving the limiting effect of the tank body 1 on the heat exchange box 2. When disassembling the heat exchange box 2, the threaded hole 15 is rotated in the opposite direction to disengage the threaded hole 15 from the plug plate 14, and the heat exchange box 2 is moved upward to drive the plug plate 14 and the top rod 16 to move upward. The second spring 18 pulls the second cover plate 20 and the retaining cylinder 19 to move upward until the top rod 16 is disengaged from the U-shaped plate 12, thereby realizing the disassembly of the heat exchange box 2. The second cover plate 20 cooperates with the retaining cylinder 19 to cover the top of the tank body 1, thereby preventing the exhaust gas in the tank body 1 from being discharged to the outside and reducing heat loss. The first connecting component and the second connecting component can be easily connected and disassembled, and the operation is simple, which is suitable for promotion.
