Spittoon rotation device

Abstract

The invention discloses a spittoon rotation device. The device comprises a fixing base, a rotating cylinder, an electric disk which fixedly sleeves the rotating cylinder and an electric motor mountedon the fixing base, a rotating hole is formed in the fixing base, the rotating cylinderrotatably sleeves in the rotating hole, the rotating cylinderrotatably sleevesa driven gear, a magnet ring is arranged between the driven gear and the electric disk, the magnet ring is fixedly connected with the driven gear, when the electric disk is energized, the electric disk can magnetically attract the magnet ring, the output shaft of the electric motoris connected with a driving gear which is meshed with the driven gear, a spittoon is mounted on the rotating cylinder, when the spittoon is manually rotated, the electric disk and the motor are simultaneously de-energized, the electric disk does not generate a magnetic force,the output shaft of the electric motor does not follow the rotation of the spittoon, the deceleration of the electric motor itself is eliminated, so that in the case of manual adjustment, the spittoon can be rotated without much effort, and the operation is convenient. The device is used for the installation of the spittoon on a dental comprehensive treatment machine.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a spittoon rotating device. Background technique [0002] Dental comprehensive treatment machine is usually used for the examination and treatment of oral diseases, and it is the main diagnosis and treatment equipment of stomatology. The comprehensive dental treatment machine is mainly composed of the main box, spittoon, instrument arm, instrument tray, assistant frame, dental light and matching dental chair, and the rotation of the spittoon is for patients to obtain better The spitting position or the medical staff can obtain a larger operating space. The existing spittoon rotation structure includes manual rotation, electric rotation, or manual and electric integrated rotation. The more advanced one is the manual and electric integrated rotation, but this Integrated rotation, when switching to manual mode, often because the transmission mechanism is connected with th...

Problems solved by technology

The comprehensive dental treatment machine is mainly composed of the main box, spittoon, instrument arm, instrument tray, assistant frame, dental light and matching dental chair, and the rotation of the spittoon is for patients to obtain better The spitting position or the medical staff can obtain a larger operating space. The existing spittoon rotation structure includes manual rotation, electric rotation, or manual and electric integrated rotation. The more advanced one is the manual and electric integrated rotation, but this Integrated rotation, when switching to manual mode, often because the transmission mechanism is connected with the motor, the motor itself has a deceleration effect, and the deceleration ratio is relatively large, so that in the case of manual adjustment, it takes a lot of effort to rotate It also greatly increases the labor intensity of doctors and reduces the efficiency of the entire oral diagnosis and treatment, and because the rotation of the spittoon is used in the process of oral treatment, if the force is too large, the entire dental comprehensive treatment machine will shake, which is easy to damage the equipment. And serious cases can lead to medical malpractice
