Pressure control system.
Background technology
Toothwash, dental filling, grind one's teeth in sleep increasingly common in our daily lifes, people are in this way making up tooth
Different defects, meet beauty and reparation to tooth.In the middle of dentist mechanism, a kind of the most commonly used dental appliance is exactly dentistry
Mobile phone, the modal species of dental handpiece are divided into mobile phone at a slow speed and high speed handpiece, and mobile phone is mainly used to carry out clearly tooth at a slow speed
Wash, polish, high speed handpiece is clinically for incisal grinding tooth.
The get on the bus rotating speed of pin of mobile phone or high speed handpiece its dental handpiece heads is all very high at a slow speed, and car pin turns
Dynamic power resources are converted in the high pressure draught that dental handpiece is accessed, thus in mobile phone air pressure stability to dental handpiece
Speed stability plays conclusive impact, and air pressure crosses conference causes the car pin rotating speed on head excessive, if the normal excess loads of Jing
Rotation will affect the service life of dental handpiece, also have influence on the safety in utilization of dental handpiece, jeopardize the peace of dental care
Entirely.
Therefore it is very crucial for the air pressure in dental handpiece carries out Isobarically Control, can also effectively improves dental handpiece
Stability in use energy so that dental handpiece is safer in use, it is to avoid the fortuitous event during use send out
Raw, the service life of dental handpiece also becomes more permanent therewith.
Utility model content
The purpose of this utility model is to provide a kind of automatic constant pressure control system of dental handpiece, by Isobarically Control system
System carries out Isobarically Control to the air pressure inside dental handpiece interior tracheae, it is ensured that the air pressure in dental handpiece can keep constant pressure shape
State, improves the speed stability of dental handpiece, extends the service life of dental handpiece.
For achieving the above object, technical solution of the present utility model is：A kind of automatic constant pressure control of dental handpiece
System, including：Conduit, spring, overflow air-casing, pressure release set, it is characterised in that：Overflow air-casing and spring, institute are cased with described conduit
Excessive gas port is provided with the conduit stated, described conduit and spring are placed on conduit by pressure release set；Described pressure release puts and sets
It is equipped with exhaust outlet.
Further, described tube at one end is connected with extension tube attached；
To reach more preferably implementation result, further：
Described conduit connects external pipe end and is provided with O-ring seal；
Described pressure release puts and is provided with 5 exhaust outlets；
Described pressure release puts and is provided with O-ring seal；
Described pressure release puts and is provided with airflow orifice；
Spring screens is provided with described pressure release set.
The beneficial effects of the utility model are：A kind of automatic constant pressure control system of dental handpiece, is installed on tooth during use
It is connected with dental handpiece interior tracheae in section's mobile phone, the gas pressure overflowed by supravasal excessive gas port, to air-casing and the spring of overflowing
Production squeezing action power, produces active force push the spring to the air-casing that overflows when gas pressure is excessive, when excessive air-casing exceedes pressure release set
On vent position when, excessive partial gas pressure is discharged by exhaust outlet, so as to stablize endotracheal air pressure, reaches constant pressure standard,
The tracheae for guaranteeing dental handpiece will not be excessive and cause dental handpiece rotating speed too fast, dental handpiece is caused to damage, it is to avoid because of tooth
Section's mobile phone using when failure and cause malpractice.Dentistry is improved by the automatic constant pressure control system of this practical dental handpiece
The speed stability of mobile phone, extends the service life of dental handpiece, also ensures that dental handpiece security in use.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail, it is therein schematic
Embodiment and explanation are only used for explaining the utility model, but are not intended as to restriction of the present utility model.
Referring to accompanying drawing 1-2, the utility model：A kind of automatic constant pressure control system of dental handpiece, including：Conduit, spring,
Excessive air-casing, pressure release set, its tube at one end are connected with extension tube attached, and extension tube attached is used to connect air pressure incoming end, conduit connection extension tube attached
End is provided with O-ring seal, it is ensured that sealing when air pressure is accessed, and is cased with overflow air-casing and spring, is provided with conduit on conduit
Excessive gas port, the gas port that overflows are communicated with the air pressure in conduit, and its excessive air-casing and spring are placed on conduit by pressure release set, are set in pressure release set
Spring screens is equipped with, spring screens namely arranges the less raised circular hole of diameter in pressure release set, by spring screens pair
Spring one end carries out stuck positioning, on the other hand entangles conduit and is fixed, and pressure release puts and is provided with O-ring seal, its pressure release
When set one end connects the tracheae of dental handpiece（The tracheae insertion pressure release of dental handpiece is covered in one end）, it is O-shaped close that pressure release puts
Seal can ensure that the sealing of pressure release set, and pressure release puts and is provided with airflow orifice, and airflow orifice guarantees that excessive air-casing and spring are being led
At pipe overflow gas port during the extruding of air pressure, the active force of back draught in pressure release set, pressure release will not be subject to put and be provided with exhaust
Mouthful, when air pressure crosses the excessive air-casing of senior general is depressed beyond the exhaust outlet that pressure release puts, excessive partial gas pressure is discharged by exhaust outlet,
So as to stablize endotracheal air pressure, pressure release puts and is provided with 5 exhaust outlets, simply preferably embodiment, the quantity of exhaust outlet
Depending on the demand of air pressure is mediated according to practicality, this does not constitute to the utility model and limits.
Use principle：The utility model using when be installed in dental handpiece, the connection of tracheae in dental handpiece is lost heart set,
When extension tube attached accesses air pressure, air pressure is normally run into the tracheae of dental handpiece through conduit, and supravasal excessive gas port overflows
Go out normal gas pressure, to air-casing and the spring production squeezing action power of overflowing（The air-casing that now overflows will not produce mobile change, spring
Pressure can carry out presetting customization according to the normal barometric pressure of dental handpiece）, the air-casing that overflows is produced when gas pressure is excessive
Active force push the spring, when excessive air-casing is more than the vent position that pressure release puts, excessive partial gas pressure is discharged by exhaust outlet, from
And stablize endotracheal air pressure, reach constant pressure standard, it is ensured that the tracheae of dental handpiece will not be excessive and causes dental handpiece rotating speed
It is too fast, to dental handpiece cause damage, it is to avoid because dental handpiece using when failure cause malpractice.By this practical tooth
The automatic constant pressure control system of section's mobile phone improves the speed stability of dental handpiece.
The above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
Construction, the equivalence changes done of feature and principle or modification, be included in the utility model patent claim.
