Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides dental treatment by blowing out pressurized air from a tip nozzle and a dental handpiece that completely cuts teeth, etc. by rotating an air turbine or air motor driven by pressurized air. A chair equipped with multiple dental treatment instruments operated by pressurized air, such as a dental syringe, is used in a dental unit, etc. Even when one treatment instrument is in use, it is possible to easily move the parts of other treatment instruments, such as the hand. This relates to a pressurized air "1τj control device for dental treatment instruments that allows for the replacement of cutting bars, etc. of pieces, and repair of defective parts. Normally, dental units, etc. are equipped with a technician The pressurized air from the handpiece and the tip nozzle is moved by pressurized air of different numbers of rice grains with different rotational speeds and rotational torques so that they can be selected according to the treatment mode.

Water or fog k'! It is equipped with dental treatment instruments such as syringes that are used to dry and clean the affected area, and pressurized air is supplied to all the hangers that hang on the treatment instruments. e-controlled air signal switches (iii

Therefore, according to the conventional configuration, when a technician is performing dental treatment using a treatment instrument that has been removed from the hanger, an assistant may remove the bunker from the bunker to replace the cutting bar on another handpiece, for example. When the handpiece is removed, the handpiece is also driven by the supply of pressurized air from the air signal switch, so when performing dental treatment with one treatment instrument, the handpiece can be operated with the help of pressurized air. This has the inconvenience of not being able to perform tasks such as replacing parts of treatment equipment.
There was a flaw in that treatment efficiency was also impaired by Katsone.

Therefore, we provide a pressurized air signal system for treatment instruments that eliminates these drawbacks.The embodiments of the present application will be described below in detail with reference to the drawings. , -i solid lines indicate the control (g-phase pressurized nitrogen air passages).The Caro pressure air source fi+ includes a filter (2), residual pressure iP+3+ [iii'a: A normally closed hood controller (4) that controls the hood is connected to the output side of this foot controller/troller, and the dental number 1/dobies t51a, which has a mantissa with a different rotational speed and rotating torque controller, is connected to the output side of this foot controller/troller. 51b

Figure 3 shows a cross-sectional view 2 of a part of the dental unit's sleeve, which extends horizontally and has a diagonal notch at the tip.

A pressing piece 09 extending inside the folding plate 31 is fixed, and the L is aligned along the front surface of the pressing piece 09 of the cutter and the lower surface of the mounting plate 06).
The eyebrows are bent in the shape of a letter A and a reinforcing member is provided, and the mounting plate (+6) is always urged between the upper parts by a spring (21). t121 cuts off the pressurized air cartridge signal by pressing the rJfl This is a member that operates the Ail hanger switch by following the pressurized air signal, and supplies pressurized air to the cylindrical body (fixed to the lower surface of the inner side of the cylindrical body 1z1); j Eri hold/ :')
