The cross reference of related application
This application claims the U.S. Provisional Patent Application in 2 months Application No. 62/120,685 submitted for 25th in 2015
Rights and interests, entire contents are incorporated herein by reference.
The content of the invention
Dental handpiece may include head and rotating part.Head may include turbine and be oriented to guide light attached in turbine
The nearly light guide portion for leaving head.Rotating part may include to be oriented to the light emitting diode incidented light in light guide portion
(LED) detachable battery and for LED powered.
The supplementary features and advantage of the present invention will illustrate in the description that follows, and part will be apparent from description
Or can be known by the practice of the present invention.The features and advantages of the present invention can be by particularly pointing out in appended claims
Instrument and combination realize and obtain.These and other features of the invention will become from the following description and the appended claims
It must become apparent from, or can be known by the practice of the invention being set forth below.
Brief description of the drawings
The mode of advantages and features of the invention can be obtained for description, by by referring to specific illustrative shown in accompanying drawing
Embodiment is next, and present invention is described.Understanding, these accompanying drawings only describe the typical embodiment of the present invention, therefore not
It is considered as restriction on its scope, the present invention will be described and explained by using accompanying drawing.
Fig. 1 shows the exploded view of dental handpiece according to an embodiment of the invention.
Fig. 2 shows the cross-sectional view of Fig. 1 dental handpiece.
Embodiment
Fig. 1 shows the exploded view of dental handpiece 10 according to an embodiment of the invention.Dental handpiece 10 includes the He of head 12
Rotating part 14.Head 12 could attach to rotating part 14 and detachable from rotating part 14, and when being attached to rotating part 14, head
12 can rotate freely relative to rotating part 14.Rotating part 14 can be configured to be attached to conventional air and water source.
The head 12 of dental handpiece 10 may include turbine 16 at one end, and light guide portion outlet 18 can be positioned
Into close to turbine 16 so that working surface can be bright by the illumination from the transmitting of light guide portion outlet 18.The main body 20 on head can be by
The material that autoclaved such as stainless steel, aluminium or such as heat resistance polymer of polyether-ether-ketone (PEEK) can be born is made.
The rotating part 14 of dental handpiece 10 may include to be oriented at first end to inject light into when with head 12 coupling
To the light emitting diode (LED) 22 in the light guide portion 24 (referring to Fig. 2) on head 12.Second end of rotating part 14 may include to be used for
Air and water source are attached to the connection part 26 of dental handpiece 10.
The cavity (cavity) 28 formed in rotating part 14 is designed to accommodate the size of battery unit 30 wherein
And it is configured to accommodate battery unit 30 wherein.For electrical contacts corresponding with battery unit 30 electrical connection
Multiple electrical contacts 32 can be located in cavity 28.In addition, cavity 28 may include for accommodating the corresponding protrusion on battery unit 30
The hole 34 in portion, this can help to the rotating part 14 that battery unit 30 is fixed to dental handpiece 10.
As shown in Fig. 2 battery unit 30 may include rechargeable battery 36 wherein and for starting battery unit
30 starting switch 38.When battery unit 30 is installed in the cavity 28 of rotating part 14, it is positioned in rotating part 14
Magnet 40 can magnetic attachment be located at metallic plate 42 in battery unit 30, battery unit 30 is maintained in cavity 28 until enough
Power be applied to battery unit 30 to overcome magnetic force and remove battery unit 30.
Control circuit 44 can be between battery 36 and LED 22.As illustrated, control circuit 44 can be located at battery unit
In 30, it can be located in rotating part 14 or a part can be located in battery unit 30 and a part can be located in rotating part 14.
Control circuit 44 may include starting switch 38, timer, accelerometer, second switch and capacitor.When startup is opened
When pass 38 and second switch close, electric power will be directed into capacitor, be then guided to LED 22.Starting switch 38 can lead to
Operator's pressing is crossed to be located at the button 46 on battery unit 30 and close.Starting switch 38 will not sense fortune in accelerometer
Remained closed in special time after dynamic, timer will open starting switch afterwards.Second switch will be responsive to by accelerating
Degree is counted the motion of sensing and closed, and if accelerometer does not sense motion, then it will be opened.In starting switch 38
And/or after second switch is opened, LED 22 will no longer receive the electric power from battery, but it will receive and within a period of time
The electric power of sufficient power from capacitor is completed until capacitor discharge.
Therefore, after operator presses button 46 to close starting switch 38, LED 22 will use dentistry in operator
It is powered during mobile phone 10 and illumination is provided.After mobile phone 10 has been laid down and is continued for some time and is not moved, LED 22
It will turn off, it slowly extinguishes due to capacitor.
As shown in Fig. 2 LED 22 and light guide portion 24 can be positioned in head 12 relative to hand close to LED 22 one end
At the rotation axis of the rotating part 14 of machine 10.No matter head 12 rotates in which direction relative to rotating part 14, this configuration
All LED 22 is allowed to emit light into light guide portion 24.Position, be guided through at rotation axis in order to facilitate LED 22
The air of passage 48 in rotating part 14 at the rotation axis is radially outward directed across the of LED 22 and rotating part 14
The opening 50 of opening position between two ends, and be directed into and to be formed in the toroidal cavity between rotating part 14 and head 12.So
Afterwards, air is directed into turbine 16 from toroidal cavity by the passage in the head 12 away from rotation axis positioning.
The present invention can be implemented in the form of other are specific.Described embodiment is to be considered merely as illustrative in all respects
And it is nonrestrictive.Therefore, the description of the scope of the present invention by appended claims rather than above indicates.In claim
All changes in equivalent implication and scope are included within the scope of claim.
