[0031] The first switch is also electrically connected to the water pump 15. The water pump 15 is controlled to work by the first switch. When the first switch is turned on, the semiconductor cooling sheet 18 and the water pump 15 work simultaneously, thereby cooling the seat cushion.

[0032] like Figure 4 As shown, a water inlet pipe 17 is provided on the side wall of the first water tank 2, the hose 16 is connected to one end of the water inlet pipe 17, the other end of the water inlet pipe 17 extends to the inside of the first water tank 2, the first water tank 2 is rotatably connected with a first rotating shaft 20, the outside of the first rotating shaft 20 is fixedly connected with a first water baffle plate 21 and a pressure rod 22, the pressure rod 22 is located below the first water baffle plate 21, and one end of the first water baffle plate 21 away from the first rotating shaft 20 is in contact with the water inlet pipe 17. Under normal conditions, the first water baffle plate 21 can completely block the end of the water inlet pipe 17, and a first spring 23 is fixed on the inner wall of the first water tank 2, one end of the first spring 23 is connected to the first water baffle plate 21, and the water inlet pipe 17 is blocked by the elastic force of the first spring 23 and the first water baffle plate 21.

[0033] A first support plate 25 is fixedly provided on the inner wall of the first water tank 2, and a second rotating shaft 26 is rotatably connected to the bottom plate of the first water tank 2. The axis of the second rotating shaft 26 is parallel to the axis of the first rotating shaft 20. The second rotating shaft 26 passes through the first support plate 25 and is rotatably connected to the first support plate 25, so that the second rotating shaft 26 is supported by the first support plate 25. A water wheel 27 is fixedly connected to the second rotating shaft 26, and the water wheel 27 is located between the first support plate 25 and the bottom plate of the first water tank 2. A fan blade 28 is fixedly connected to the top of the second rotating shaft 26. When the water wheel 27 rotates, the fan blade 28 can be driven to rotate through the second rotating shaft 26.

[0034] A water trough plate 24 is arranged below the water inlet pipe 17 . The water trough plate 24 is arranged at an angle, one end of which is fixedly connected to the inner wall of the first water tank 2 , and the other end of the water trough plate 24 is arranged opposite to the water wheel 27 .

[0035] A third rotating shaft 29 is also provided in the first water tank 2, and both ends of the third rotating shaft 29 are rotatably connected to the inner walls on both sides of the first water tank 2 respectively, and the axis of the third rotating shaft 29 is perpendicular to the axis of the second rotating shaft 26. A second water baffle 31 is fixedly connected to the third rotating shaft 29, and a second support plate 30 is provided on the side wall of the first water tank 2. The second support plate 30 is arranged parallel to the first support plate 25, and one end of the second support plate 30 away from the side wall of the first water tank 2 extends to directly above the second water baffle 31. A second spring 32 is provided between the second support plate 30 and the second water baffle 31, and one end of the second spring 32 is fixedly connected to the second support plate 30, and the other end is fixedly connected to the second water baffle 31.

[0036] A first opening 33 is provided at the bottom of the first water tank 2, and a second opening 34 is provided at the top of the second water tank 3. The second opening 34 is arranged corresponding to the first opening 33. The first opening 33 and the second opening 34 are arranged so that the interior of the first water tank 2 and the interior of the second water tank 3 are connected. The second water baffle plate 31 covers the first opening 33, so that the first opening 33 is blocked by the second water baffle plate 31.

[0037] The pressure rod 22 on the first rotating shaft 20 is located directly above one end of the second water baffle plate 31. When the first rotating shaft 20 rotates, the pressure rod 22 rotates with the first rotating shaft 20 and contacts the top surface of the second water baffle plate 31, pressing the second water baffle plate 31, thereby using the second water baffle plate 31 to block the first opening 33. When the first rotating shaft 20 is reset, the pressure rod 22 leaves the second water baffle plate 31, and the second water baffle plate 31 is lifted up under the action of the second spring 32, thereby opening the first opening 33.

[0038] The cooling water in the second water tank 3 enters the water inlet pipe 17 through the water pump 15 and the hose 16. Under the action of the water pump 15, the cooling water impacts the first water baffle 21 to rotate the first rotating shaft 20 and the pressure rod 22 and compress the first spring 23. When the pressure rod 22 rotates, it presses the second water baffle 31 and stretches the second spring 32, so that the second water baffle 31 is used to block the first opening 33 to prevent the cooling water in the first water tank 2 from flowing back to the second water tank 3. The water impacting the first water baffle 21 falls from the water trough plate 24. Since the water trough plate 24 is arranged at an angle, the discharged water will generate an impact potential energy, which is used to impact the water wheel 27 to drive the second rotating shaft 26 and the fan blade 28 to rotate.

[0039] A plurality of exhaust holes 19 are provided on the top of the first water tank 2, and the fan blades 28 are arranged opposite to the exhaust holes 19. After the cooling water enters the first water tank 2, the cold air generated is discharged from the exhaust holes 19 into the bottom of the cushion mechanism to cool the cushion 4. The rotation of the fan blades 28 can improve the circulation of air, so that each exhaust hole 19 has cold air discharged, which is conducive to uniformly cooling the cushion 4 and preventing the cushion 4 from being hot in one area and cold in another. When the water in the second water tank 3 is exhausted, the first water baffle 21 is no longer impacted, and then the first spring 23 is reset to make the first water baffle 21 move the water inlet pipe 17 is blocked to prevent impurities from entering. When the first spring 23 is reset, it will drive the pressure rod 22 to rotate in the opposite direction through the first rotating shaft 20 to reset. At this time, the pressure of the pressure rod 22 on the second water baffle 31 disappears, and then the second spring 32 is reset to drive the second water baffle 31 to reset and open the first opening 33. At this time, the water in the first water tank 2 enters the interior of the second water tank 3 through the first opening 33 and the second opening 34, and then the semiconductor refrigeration plate 18 cools the water in the second water tank 3 again, and then it is discharged to the interior of the first water tank 2 through the water pump 15, which is conducive to this reciprocating operation to complete the cycle cooling.

[0040] The cushion mechanism includes a cushion 4 and a disassembly mechanism, and the cushion 4 is fixed above the first water tank 2 by the disassembly mechanism. Figure 5 As shown, the disassembly and assembly mechanism includes a hollow column 6 and an insertion rod 7, a hard plate 5 is provided at the bottom of the cushion body, four insertion rods 7 are provided, and the four insertion rods 7 are symmetrically arranged at the four corners of the hard plate 5, four hollow columns 6 are provided, which are respectively located at the four corners of the first water tank 2, and the top of the hollow column 6 extends out of the outside of the first water tank 2, and the top end of the hollow column 6 is opened, and a plug 8 is provided at the end of the insertion rod 7 away from the hard plate 5, and the plug 8 is a conical structure, and a groove 9 is provided at the connection between the plug 8 and the insertion rod 7.

[0041] A first circular groove 10 and a second circular groove 11 are provided inside the hollow column 6. A limit block 12 is provided inside the first circular groove 10. An electromagnet 14 is installed on the inner wall of the first circular groove 10. The limit block 12 is made of iron material and is elastic and can be adsorbed by the electromagnet 14. The electromagnet 14 is electrically connected to the battery and can supply power to the electromagnet 14.

[0042] The handles on both sides of the seat cushion 4 are provided with second switches, which are electrically connected to the battery and the electromagnet 14 respectively, and the electromagnet 14 is energized by the second switch.

[0043] Specifically, the limit block 12 includes a limit rod 13, and a plurality of limit rods 13 are provided. The plurality of limit rods 13 are located at one end of the limit block 12. When the insertion rod 7 is inserted into the hollow column 6, the limit rod 13 is compressed and opened, and then the plug 8 enters the interior of the second circular groove 11, and the rod body of the insertion rod 7 is located inside the first circular groove 10. Thereafter, the limit rod 13 is reset to press against the groove 9, thereby fixing the insertion rod 7 inside the hollow column 6, realizing the connection between the insertion rod 7 and the hollow column 6, and then realizing the quick installation of the seat cushion 4.

[0044] When the seat cushion becomes concave due to long-term sitting and needs to be replaced with a new one, the button battery in the hollow column 6 is controlled to power the electromagnet 14 to make it energized. The energized electromagnet 14 attracts the limit rod 13, and then the limit rod 13 leaves the position of the groove 9. After that, the seat cushion 4 is lifted and the insertion rod 7 leaves the inside of the hollow column 6 to complete the quick disassembly.
