[0039] A first air slip ring 26 and a second air slip ring 261 are respectively sleeved on both ends of the transmission shaft 21. The first air slip ring 26 is located above the second air slip ring 261. Both the first air slip ring 26 and the second air slip ring 261 are arranged on the desalination cylinder 11. The fixed cylinder 231, the telescopic cylinder 232 and the interior of the transmission shaft 21 are interconnected. The upper end of the transmission shaft 21 is connected to the inlet of the first air slip ring 26 via a pipeline. The outlet of the first air slip ring 26 is connected to a pressure pump (not shown) via a pipeline.

The cleaning liquid enters the inlet of the second air slip ring 261 from the filling port 262 and is then transported to the cleaning ball 23 through the outlet of the second air slip ring 261 and the hose, thereby replenishing the cleaning liquid.

[0041] A first electric ring 24 is provided at the bottom of the desalination cylinder 11 opposite to the transmission shaft 21. The first electric ring 24 is located outside the filling port 262. A second electric ring 241 is provided on the inner wall of the sleeve 115 outside the first electric ring 24. Both the first electric ring 24 and the second electric ring 241 are electrically connected to the control system.

[0042] Several high-temperature plates 25 are provided on the inner wall of the connecting pipe 112, several low-temperature plates 251 are provided on the inner wall of the desalination cylinder 11 above the partition 114, and several refrigeration plates 31 are provided on the cooling plate 3. The high-temperature plate 25, the low-temperature plate 251 and the refrigeration plate 31 are all provided with a connecting plate and two semiconductors of different materials. The connecting plate is made of metal, and one end of the two semiconductors of different materials is connected to the connecting plate. The two semiconductors on the high-temperature plate 25 and the two semiconductors on the low-temperature plate 251 are connected by wires, one of which is connected to the control system, and the two semiconductors on the refrigeration plate 31 are electrically connected to the control system through wires.

[0043] Solenoid valves and flow meters are installed in the liquid inlet pipe 113, the liquid outlet pipe 111, the connecting pipe 112 and the sewage pipe 119, and the solenoid valves and the flow meter are electrically connected to the control system; a cooling chamber is formed between the upper side of the partition 114 and the desalination cylinder 11, and a distillation chamber is formed between the lower side of the partition 114 and the desalination cylinder 11. The connecting pipe 112 connects the cooling chamber and the distillation chamber, the liquid inlet pipe 113 and the sewage pipe 119 are connected to the distillation chamber, and the liquid outlet pipe 111 is connected to the cooling chamber.

[0044] Working principle: Press the start button on the control panel 1, the control system opens the solenoid valve in the liquid inlet pipe 113, and transports the seawater to be desalinated into the liquid inlet pipe 113 through the liquid supply system. The seawater enters the distillation chamber through the liquid inlet pipe 113, and the liquid supply system feeds back the flow data of the seawater to the control system. The control system drives the transmission shaft 21 to rotate through the drive motor 2, and energizes the coil 116 between the several first stirring plates 22, so that the metal material in the several first stirring plates 22 is located in the magnetic field of the coil 116, while the metal plate 234 in the cleaning ball 23 is not located in the magnetic field of the coil 116. The transmission shaft 21 drives the cross bar 211 and the rotating cylinder 212 to revolve, and the rotating cylinder 212 drives the follower gear 213 and the first stirring plate 22 to follow the revolution. While the follower gear 213 revolves, it alternately meshes with the first arc rack 117 and the second arc rack 118;

[0045] When the follower gear 213 is meshed with the first arc rack 117, the follower gear 213 rotates in the forward direction, and the follower gear 213 drives the first stirring plate 22 to rotate in the forward direction via the rotating cylinder 212; when the follower gear 213 is meshed with the second arc rack 118, the follower gear 213 rotates in the reverse direction, and the follower gear 213 drives the first stirring plate 22 to rotate in the reverse direction via the rotating cylinder 212;

[0046] The follower gear 213 is alternately engaged with the first arc rack 117 and the second arc rack 118, thereby realizing the revolution and rotation of the first stirring plate 22. The rotating and self-rotating first stirring plate 22 cuts the magnetic flux lines in the magnetic field of the coil 116, and the metal material in the first stirring plate 22 generates current and generates heat. While the first stirring plate 22 stirs the seawater through the revolution and rotation, it also heats and distills the seawater through the metal material, making the seawater mixed more evenly, reducing the time and energy required for heating, making the seawater heated more evenly, and reducing energy waste. In addition, stirring can also improve water quality. During the stirring process, the flow and mixing of seawater help to remove impurities and pollutants therein, making the final fresh water purer. Stirring can promote the uniform distribution of suspended matter and dissolved matter in the water, and reduce the possibility of local accumulation of impurities.

[0047] While the first stirring plate 22 is distilling the seawater, the driving motor 2 also drives the fixed cylinder 231 to revolve through the transmission shaft 21. The fixed cylinder 231 drives the telescopic cylinder 232, the cleaning ball 23 and the expansion ball 233 to revolve, and the telescopic cylinder 232 drives the second stirring plate 235 to revolve. The encoder inside the driving motor 2 feeds back data to the control system. The control system pressurizes the external air through the pressure pump and then transmits it to the inside of the transmission shaft 21 through the pipeline and the first air slip ring 26. The pressurized air passes through the inside of the transmission shaft 21 and enters the inside of the fixed cylinder 231 and the telescopic cylinder 232. The pressurized air pushes the telescopic cylinder 232 to move away from the fixed cylinder 231. The telescopic cylinder 232 simultaneously stretches the reset spring, and the telescopic cylinder 232 drives the second stirring plate 235 to move away from the fixed cylinder 231, so that the distance between the second stirring plate 235 and the center of the transmission shaft 21 increases.

[0048] When the second stirring plate 235 moves to the outermost side, the pressure pump feeds back the air pressure signal to the control system, and the control system reverses the pressure pump operation. At this time, the reset spring is released, and the reset spring pulls the telescopic cylinder 232 to move closer to the fixed cylinder 231. The air between the telescopic cylinder 232 and the fixed cylinder 231 is extracted into the atmosphere through the transmission shaft 21, the first air slip ring 26 and the pressure pump. The telescopic cylinder 232 drives the second stirring plate 235 to move closer to the fixed cylinder 231, so that the distance between the second stirring plate 235 and the center of the transmission shaft 21 becomes smaller.

[0049] Through the forward and reverse operation of the pressure pump and in cooperation with the reset spring, the second stirring plate 235 is moved back and forth along the axial direction of the fixed cylinder 231, driving the seawater at different positions at the bottom of the distillation chamber to move upward, so that the seawater at different positions is in contact with the first stirring plate 22 for distillation treatment, so as to generate more water vapor and improve the distillation efficiency and seawater desalination efficiency.

[0050] The distilled seawater generates water vapor and is transported to the cooling chamber of the desalination cylinder 11 through the connecting pipe 112. The flow meter in the connecting pipe 112 feeds back the flow data of the water vapor to the control system. The high-temperature plate 25 in the connecting pipe 112 first contacts the high-temperature steam. Then, the high-temperature steam contacts the refrigeration plate 31 on the cooling disk 3. The control system connects the two semiconductors on the refrigeration plate 31 to the circuit. The two semiconductors and the connecting plate on the refrigeration plate 31 are the refrigeration ends of the Peltier effect. The high-temperature steam is cooled by the refrigeration end, so that the cooled water vapor becomes liquid and is discharged from the liquid outlet pipe 111. The staff automatically samples the desalinated seawater from the liquid outlet pipe 111.

[0051] When the flow meter in the connecting pipe 112 detects the flow of high-temperature water vapor, the two semiconductors and the connecting plate on the high-temperature plate 25 are the hot ends of the Seebeck effect, and the two semiconductors and the connecting plate on the low-temperature plate 251 are the cold ends of the Seebeck effect. The hot end temperature is higher than the cold end. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system processes the current and uses it to cool the refrigeration end.

[0052] After long-term distillation and cooling of seawater, a large amount of impurities (mainly scale) will be deposited at the bottom of the desalination cylinder 11. The inside of the desalination cylinder 11 needs to be cleaned so that it can be used again. The control system connects the coil 116 outside the fixed cylinder 231 to the circuit, so that the metal plate 234 inside the cleaning ball 23 is located in the magnetic field of the coil 116, and drives the transmission shaft 21 to rotate through the driving motor 2. The transmission shaft 21 drives several fixed cylinders 231 to rotate, and several fixed cylinders 231 drive the telescopic cylinder 232 to rotate. The telescopic cylinder 232 drives the cleaning ball 23 to rotate. The brush on the cleaning ball 23 cleans the desalination cylinder 11 at the same time, and the cleaning ball 23 drives the expansion ball 2 33 and the metal plate 234 rotate accordingly, so that the metal plate 234 cuts the magnetic flux lines in the magnetic field of the coil 116, while the metal material in the first stirring plate 22 is not in the magnetic field of the coil 116. Current is generated in the metal plate 234 and heat is generated. The metal plate 234 conducts heat to the heat-conducting medium. The heat-conducting medium expands due to heat, and the heat-conducting medium squeezes the expansion ball 233, so that the diameter of the expansion ball 233 gradually increases, and the pressure of the cleaning liquid between the expansion ball 233 and the cleaning ball 23 gradually increases. At this time, the cleaning liquid pushes open the one-way valve in the spray hole, and the cleaning liquid is sprayed from the spray port on the bottom of the desalination cylinder 11, and cooperates with the brush on the cleaning ball 23 to achieve cleaning of the bottom of the desalination cylinder 11.

[0053] After the desalination cylinder 11 is brushed with a brush and cleaned with cleaning liquid, most of the impurities in the desalination cylinder 11 are gathered in the cleaning liquid, while a small number of impurities that are difficult to clean will need further cleaning; the control system connects the first electric ring 24 and the second electric ring 241 to the positive pole and the negative pole of the power supply respectively, so that current flows through the cleaning liquid between the first electric ring 24 and the second electric ring 241, prompting the bicarbonate ions in the cleaning liquid or impurities to react with the first electric ring 24 and the second electric ring 241, thereby dissolving the scale. Afterwards, the control system opens the solenoid valve in the drain pipe 119 to discharge the dissolved scale from the drain pipe 119.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
