AI Technical Summary

Technical Problem

The existing root canal preparatory machine head design is prone to corrosion of circuit boards and solder joints due to water vapor during steaming and disinfection, resulting in a shortening of the service life of the equipment. The existing sealing solution increases the diameter of the head or is difficult to repair.

Method used

The casing assembly is used to form a cavity with the gear box, and the water vapor is isolated through the first seal. The circuit board is arranged in the cavity. The light-transmissive structure is connected to the light-guiding fiber. The second seal further isolates the water vapor, ensuring that the circuit board and the light-emitting part are not affected, and the design is compact and easy to repair.

Benefits of technology

Effectively prevent water vapor corrosion, extend the equipment life, while keeping the head compact, not increasing the diameter, reducing processing difficulty and cost, and improving product qualification rate.

Abstract

The invention discloses a root canal preparation machine bending machine head which comprises a shell assembly, a gear box, a circuit board and a light-emitting part, and the shell assembly is provided with an assembling groove. The gearbox is assembled in the assembling groove, a cavity is formed by the outer surface of the gearbox and the inner surface of the shell assembly, and the cavity is provided with a first sealing piece so that the cavity can be isolated from external water vapor. The circuit board is arranged in the cavity. The light-emitting part is electrically connected with the circuit board. When the gearbox is assembled on the shell assembly, a cavity is formed between the gearbox and the shell assembly, the first sealing pieces are arranged at the two ends of the cavity, the cavity between the two first sealing pieces is isolated from external water vapor, the circuit board is arranged in the cavity, and therefore isolation protection of the circuit board is achieved; and corrosion of external water vapor to the circuit board and welding spots in the cooking disinfection process is avoided, so that the service life of the equipment is prolonged. And the two ends of the cavity are sealed through the first sealing piece and the second sealing piece, and free disassembly of the gearbox and the circuit board is not affected.
