Problems solved by technology

However, because the universal arm adopts a hollow tube, which is used as a support and as a channel, when the mist and dirt generated during dental operations enter the universal arm tube, they will accumulate in the universal arm tube. In the middle, after a long time, it is necessary to replace the entire universal arm and waste materials; it may even stick the joint of the universal arm so that it cannot rotate and damage the entire dust collection device
And because both the universal support arm and the dust collection hood have weight, they all need to be supported by other pillars, resulting in a complex structure

Description

technical field [0001] The invention relates to a dental dust suction device. Background technique [0002] Chinese patent document CN2277763Y discloses a dust suction device for a dentist workbench, which is composed of a universal support arm, a ventilation pipe arranged inside the universal support arm, and a cover body and a vacuum cleaner respectively combined at both ends of the ventilation pipe, which can be flexed and stretched freely. The universal support arm is composed of multiple hollow pipes pivoted together. The front end of the support arm is equipped with a flexible body, which is connected with the cover body. The universal support arm can be pivoted on the fulcrum of the lamp or erected on the working side of the stage. However, because the universal arm adopts a hollow tube, which is used as a support and as a channel, when the mist and dirt generated during dental operations enter the universal arm tube, they will accumulate in the universal arm tube. ...
