[0023] The outer shell 1 is made of stainless steel, and the iron core column 2 is made of stacked cold-rolled oriented silicon steel sheets with high magnetic permeability. This material can efficiently conduct magnetic fields. After the primary winding 3 is energized with alternating current, an alternating magnetic field is generated in the iron core column 2 based on the principle of electromagnetic induction.
[0024] Among them, the overload protection switch 7 is a thermal-magnetic overload protector with automatic reset function. When an abnormal situation occurs in the circuit, causing the current to exceed the rated value, the thermal element in the overload protection switch 7 will heat up and deform due to excessive current, pushing the tripping mechanism to act and quickly cut off the circuit in a short time to prevent the transformer and other electrical components from being damaged due to excessive current.

[0026] As shown in the figure, Figure 5 Temperature detection assembly 5 includes temperature sensor 51 and probe 52, temperature sensor 51 is arranged at the back side of shell 1, the back end of probe 52 extends to the outlet of outlet pipe 43, the inner end of probe 52 is fixedly connected to the side wall of temperature sensor 51, the temperature of liquid at the outlet of outlet pipe 43 is sensed through probe 52, the back end of probe 52 extends to the outlet of outlet pipe 43, liquid temperature information can be accurately obtained in real time and transmitted to temperature sensor 51;
[0027] As shown in the figure, Figure 3 Control assembly 6 includes microcontroller 61 and wire 62, the top end of wire 62 is fixedly connected to the side wall of microcontroller 61, the bottom end of wire 62 is connected to the side wall of primary winding 3, microcontroller 61 controls primary winding 3 through wire 62, maintains or increases current input, so that winding pipe 41 generates more heat and improves liquid heating temperature.
[0028] Working principle: as shown in the figure, Figures 1-5 When external power supply is connected to the system through power input end 8 arranged at the left end of shell 1, current flows into primary winding 3 wound on the side wall of core column 2, since core column 2 is made of cold-rolled oriented silicon steel sheet with high magnetic permeability, this material can efficiently conduct magnetic field, after alternating current is input into primary winding 3, based on electromagnetic induction principle, alternating magnetic field is generated in core column 2;
[0029] Winding pipe 41 as secondary winding 4 directly acts as a short-circuit coil, according to electromagnetic induction law, when alternating magnetic field passes through winding pipe 41, induced current is generated in it, since winding pipe 41 is made of material with certain resistance, heat is generated in winding pipe 41 according to Joule's law Q=I²Rt when current passes through, that is, the heating element is the pipe itself;
[0030] Liquid flows in from the water inlet pipe 42, which is coiled around the right end of the side wall of the shell 1 and is fixedly connected to the top end of the winding pipe 41. The liquid enters the winding pipe 41 and forms a current loop through the short-circuit wire 43 in the winding pipe 41. The liquid fully absorbs the heat generated by the induced current in the pipe, thereby realizing the heating process.

The temperature sensor 51 in the temperature detection assembly 5 is located on the rear side of the shell 1. It senses the temperature of the liquid at the outlet of the water outlet pipe 43 through the probe 52. The rear end of the probe 52 extends to the outlet of the water outlet pipe 43, which can accurately obtain the temperature information of the liquid in real time and transmit the signal to the temperature sensor 51.
[0032] The microcontroller 61 receives the temperature signal transmitted by the temperature sensor 51 and compares it with the preset temperature value. If the detected temperature is lower than the preset value, the microcontroller 61 will control the primary winding 3 to maintain or increase the current input, so that the winding pipe 41 generates more heat and increases the heating temperature of the liquid. If the detected temperature reaches or exceeds the preset value, the microcontroller 61 will control the primary winding 3 to reduce the current input or even cut off the power supply, thereby reducing the heat generated by the winding pipe 41, so as to realize accurate control of the heating temperature of the liquid.
[0033] At the same time, an overload protection switch 7 is connected in series in the circuit of the primary winding 3. It is a thermal magnetic overload protector with automatic reset function. When abnormal conditions occur in the circuit, causing the current to exceed the rated value, the thermal element in the overload protection switch 7 will deform due to excessive heat caused by excessive current, pushing the tripping mechanism to act quickly and cut off the circuit in a short time to prevent damage to the transformer and other electrical components caused by excessive current. When the fault is eliminated and the current returns to normal, the overload protection switch 7 can automatically reset and the circuit returns to normal operation.
