A heater 3 is provided on the outside of the temperature control pipe mechanism 2, which can be heated by the heater 3 to form steam. The temperature control pipe mechanism 2 circulates and heats the steam that has not reached the specified temperature until the steam reaches the specified temperature and is discharged, thereby effectively improving the overall intelligence level.

[0028] The temperature control piping mechanism 2 includes a coil 201, one end of which is provided with an inlet pipe 202, and the other end of the coil 201 is provided with an outlet pipe 204. The end of the coil 201 is connected to an external water source through the inlet pipe 202, and the end of the coil 201 is connected to an external steam-using device through the outlet pipe 204, so that water can enter the coil 201 and steam is discharged from the outlet pipe 204. A temperature sensor 205 is fixedly installed on the coil 201. The temperature sensor 205 is configured as a platinum resistance temperature sensor, model JY-PT100-4W. The PT100 platinum resistance temperature sensor has a measurement range of -200°C to 850°C, an accuracy of ±0.15% (error ≤0.45°C at 300°C), and uses a 316L stainless steel sheath and IP67 protection, suitable for high-temperature steam environments. Four-wire wiring eliminates the influence of wire resistance. The PID controller 209 is model azbil C1M, uses RS-485 (ModbusRTU protocol) for communication, PID+fuzzy control composite algorithm: coarse adjustment stage: fuzzy control accelerates temperature rise (0-250℃), fine adjustment stage: PID adaptive adjustment (250-300℃), integral separation prevents overshoot, parameter setting example: P=120, I=240s, D=30s, the input end of the PID controller 209 is connected to the temperature sensor 205, and the output end of the PID controller 209 is connected to the heater 3, so that the PID controller 209 can receive the detection signal of the temperature sensor 205 and control the heater 3 according to the detection signal. A first electric regulating valve 206 is installed on the exhaust pipe 204, and a circulation pipe 207 is installed between the top of the rear surface of the coil 201 and the inlet pipe 202. A second electric regulating valve 208 is installed at both ends of the circulation pipe 207, and the output end of the temperature sensor 205 is connected to the PID controller 209. The first electric regulating valve 206 is connected to the output end of the PID controller 209. The first electric regulating valve 206 is detachably connected to the discharge pipe 204 through a flange, so that the first electric regulating valve 206 can be easily installed and removed, and maintenance is convenient. The second electric regulating valve 208 is connected to the output end of the PID controller 209. The second electric regulating valve 208 is detachably connected to the circulation pipe 207 through a flange, so that the second electric regulating valve 208 can be easily installed and removed, and maintenance is convenient. The connection end of the PID controller 209 is connected to the touch screen 203. The touch screen 203 can set the required temperature, which is convenient for automatic temperature control. The temperature curve and fault code are displayed in real time on the touch screen 203, and a pressure sensor can be added to monitor the pressure inside the pipeline in real time. At the same time, the pressure trend is displayed on the touch screen 203, and a solenoid valve for emergency shut-off can be added to improve safety.

[0029] The heater 3 includes a surrounding portion 302, the end of which is connected to an access portion 301. The surrounding portion 302 is arranged around the outside of the coil 201, and the access portion 301 is arranged to penetrate the generator body 1, so that the coil 201 can be fully heated and the surrounding portion 302 can be easily energized. The heating method of the heater 3 adopts resistance wire heating or induction coil heating, so that the coil 201 can be quickly heated, thereby heating the water inside the coil 201 to form steam.

[0030] See also Figure 1 and Figure 6 The coil 201 includes a plurality of first tube bodies 2011 and second tube bodies 2012. The ends of the adjacent first tube bodies 2011 and second tube bodies 2012 are fixedly connected with a first fixing flange 2013. A sealing ring 2014 is installed between the first tube body 2011 and the second tube body 2012 to increase the sealing performance and facilitate the installation of the water guide sleeve 401. The anti-scaling mechanism 4 includes a water guide sleeve 401. The shape of the water guide sleeve 401 is set to be trumpet-shaped. According to the continuity equation (mass conservation), when the cross-sectional area of ​​the pipe decreases, the flow The flow velocity increases (A1v1=A2v2), and the trumpet-shaped tapered section forces the fluid to accelerate by shrinking the cross section. A small drain port 403 is provided at one end of the water guide sleeve 401. The trumpet-shaped water guide sleeve 401 gradually reduces its cross-sectional area, forcing the water flow to accelerate and compensating for the water flow that has been decelerated by the high-entropy alloy chip 404. A second fixing flange 402 is fixedly connected to the water guide sleeve 401. The high-entropy alloy chip 404 is fixedly connected to the inside of the water guide sleeve 401 and can be fixed by welding or bolts. It is made of copper (Cu) and zinc (Zn). n), nickel (Ni), tin (Sn), lead (Pb) and other multi-metal combinations form a high entropy solid solution structure. Through the 3D columnar crystal layered structure, independent yin and yang poles are formed to enhance the electron release efficiency. The surface oxide layer of the alloy is stable and the service life can reach more than 10 years. When the water flow impacts, the alloy surface releases free electrons, inducing the polarization of water molecules to form dipoles, wrapping calcium and magnesium ions (Ca²⁺, Mg²⁺), preventing them from combining with carbonate (CO3²⁻) to form scale (CaCO3, MgCO3), and the micro-current field interferes with the crystal The growth direction is such that the scale exists in the form of loose flocculent precipitation rather than hard agglomerates. A plurality of water holes 405 are provided on the high-entropy alloy chip 404, so that the water flow can fully contact the high-entropy alloy chip 404. The first fixing flange 2013 and the second fixing flange 402 can be fixed together, and the water guide sleeve 401 can be installed on the coil 201. The high-entropy alloy chip 404 inside the coil 201 releases electrons after contacting with water, preventing calcium and magnesium ions in the water from combining with carbonate to produce scale, thereby playing a good anti-scaling role.

[0031] During use, the user sets the temperature through the touch screen 203, the heater 3 heats the water inside the coil 201, the temperature sensor 205 monitors the steam temperature in real time, and transmits the detected temperature signal to the PID controller 209. The PID controller 209 compares the detected temperature signal with the set temperature. When the temperature is insufficient, the first electric regulating valve 206 is closed to close the discharge pipe 204, and the second electric regulating valve 208 is opened to open the circulation pipe 207. The steam enters the circulation pipe 207 from the top of the coil 201 and then enters the bottom of the coil 201 from the circulation pipe 207. The heating cycle is continuously performed until the temperature reaches the set temperature. The two second electric regulating valves 208 are then closed again, the first electric regulating valve 206 is opened to close the circulation pipe 207, and the discharge pipe 204 is opened to discharge the steam. Steam of the required temperature is intelligently generated, effectively improving the overall intelligence level.

[0032] The first fixing flange 2013 and the second fixing flange 402 are fixed together, and the water guide sleeve 401 is installed on the coil 201. The high entropy alloy chip 404 inside the coil 201 releases electrons after contacting water, preventing calcium and magnesium ions in the water from combining with carbonate to produce scale, thereby playing a good anti-scaling role. The electric field of the water environment is changed by physical means to avoid secondary pollution. The cross-sectional area of ​​the trumpet-shaped water guide sleeve 401 is gradually reduced, forcing the water flow to accelerate, and the water flow that is decelerated after passing through the high entropy alloy chip 404 is accelerated to compensate, preventing the fluid flow rate inside the coil 201 from being too slow, ensuring that the fluid has a certain flow rate.
