AI Technical Summary

Technical Problem

In existing water heaters, the rotation of the metal parts relative to the plastic screw head causes the metal parts to separate from the plastic screw head, creating a gap that poses a safety hazard of water leakage and electric shock.

Method used

The structure employs a combination of an insulating substrate and an insert. The insert has a locking plane and a limiting groove. When subjected to torque, the locking plane presses against the insulating substrate to prevent the insert from rotating relative to the insulating substrate, thereby enhancing structural strength and preventing the formation of gaps.

Benefits of technology

It effectively prevents rotation and movement between the insert and the insulating substrate, avoids water leakage and ensures safe use, thus improving the safety and reliability of the water heater.

Abstract

The utility model discloses a water pipe connecting structure for water heater and water heater, and belongs to water heater technical field, water pipe connecting structure for water heater includes insulating base body and embedded part, and at least partial embedded part is embedded insulating base body and is connected as a whole with insulating base body, and embedded part has the locking plane with insulating base body contact, and the locking plane is used for when embedded part is subjected to torque, and the insulating base body is pressed tightly. The water heater includes the inner bag, is provided with the inner bag joint on the inner bag, and the water pipe connecting structure for water heater is connected on the inner bag joint. When embedded part is subjected to torque, embedded part has the movement tendency of rotating around its own axis, because the locking plane is contacted with the insulating base body, the locking plane is pressed tightly the insulating base body, prevents embedded part from rotating relative to the insulating base body while increasing the structural strength, avoids the gap between embedded part and the insulating base body, prevents water leakage and prevents electric shock, and guarantees the use safety.
