A high-voltage coil is provided on the outside of the low-voltage coil and the copper tube, and an insulating part is provided between the copper tube and the high-voltage coil. The insulating part is tightly crimped through the high-voltage coil. A circulating water pump is provided on one side of the shell, and the circulating water pump is provided with a liquid inlet valve and a liquid outlet valve.

[0038] 2. Since the present invention is provided with an arc seat, after the two arc seats are closed, the inner wall thereof forms an annular cavity for accommodating the first spherical arc member and the second spherical arc member, and the first spherical arc member and the second spherical arc member are movably installed in the annular cavity. Therefore, the present invention has a certain tilting ability, can better cope with the interference of external forces, etc., and improves the practicality.

[0039] 3. The present invention can play a limiting role by providing structures such as arc-shaped limiting convex strips, thereby preventing the second spherical arc-shaped member from deflecting too much in the annular cavity of the arc-shaped seat, thereby ensuring the protection effect on the pipeline and improving reliability.

[0040] 4. The present invention can facilitate the adjustment of the position of the arc seat by providing structures such as a guide frame and a slide cylinder, thereby improving practicality; by providing structures such as a fixing portion, after adjusting the position of the arc seat, the tooth plate can be moved toward the direction close to the positioning tooth by turning the adjusting knob, thereby making the locking tooth engage with the positioning tooth, thereby fixing the position of the arc seat.

[0042] 6. The present invention provides a self-cleaning structure. When the transformer is placed outdoors, the sealing head can maintain the same height as the drain outlet based on the support of the spring and seal the drain outlet. The liquid collecting box can collect rainwater. As the collected amount increases, the liquid collecting box eventually overcomes the friction between the sealing head and the drain outlet and the elastic force of the spring, causing the liquid collecting box to fall, during which the cleaning part can clean the heat sink. During the falling process, since the drain outlet loses its seal, water can be continuously discharged from the drain outlet and finally reset based on the elastic force of the spring.

[0043] 7. The present invention provides a conical head whose diameter gradually decreases in the vertical downward direction, and an annular elastic sleeve. Under normal conditions, the annular elastic sleeve can be used to block the drain outlet. When the liquid collecting box is reset after being lowered, the conical head can play a reliable guiding role, so that the liquid collecting box is reset based on the spring rebound force, and moves upward based on inertia to overcome the friction force of the annular elastic sleeve, so that the drain outlet stays in the middle of the annular elastic sleeve to achieve reset.

[0044] 8. The present invention provides a rotating wheel and a cleaning brush, so that the surface of the heat sink can be cleaned during the lowering of the liquid collecting box, thereby improving practicality; by providing structures such as a guide groove and a cotton sleeve, when water is discharged from the drain outlet, the guide groove can be used to receive the water, and the water flows to the cotton sleeve after being guided by the guide groove. The cotton sleeve plays a certain drainage role, making it easier to wet the cleaning brush, thereby ensuring the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
