Specific embodiment
Invention is described further with reference to the accompanying drawing:
As shown in Figure 1, disposable dental handpiece, including handle 1, the head being connect with handle 12, the vehicle needle being set on head 2
3 and it is set to turbine 4 in head 2 for driving vehicle needle 3 to rotate.Handle 1 includes hollow handle housing 11 and setting
In the inner core 12 in handle housing 11.Wherein the air blowing road 13 of inner core 12 being internally provided with for blowing to turbine 4, for arranging
The exhaust duct 14 of gas extra in head 2, the water channel 15 for spraying water to vehicle needle 3 and the water mist for making in water channel 15 out
Change and spray to the atomization air flue 16 of vehicle needle 3.Wherein one end of inner core 12 is connected with head 2, and the other end of inner core 12 passes through connection
Part 17 is connected with tail connection-peg.It is provided with the gas hole 22 communicated with air blowing road 13 in head 2 and is communicated with exhaust duct 14
Gas vent 23, the length direction of the length direction of gas hole 22 and gas vent 23 perpendicular to turbine 4.The structure can guarantee gas
Body acts perpendicularly on turbine 4, improves the torque effect that turbine 4 is subject to.Mold insert hole 21, mold insert hole are set on the side wall of head 2
Setting is for being passed through water channel 15 and being atomized the mold insert 5 of air flue 16 in 21.Since general head 2 is using integrally formed work
Skill, and when needing to manufacture the hole for water spray, it is easy to produce the case where contracting hole.Both can effectively it be prevented by the setting of mold insert 5
Only the case where contracting hole, be conducive to the quality control in production process, and can freely control water channel 15 and be atomized the hole of air flue 16
Diameter size, and then water yield is controlled, it avoids water flow in oral cavity excessive, influences doctor's accurate operation, and can be to avoid disease
People frequently gets up spitting ptysis, saves treatment time.
Embodiment one
As shown in Fig. 2, be provided with the horizontal pipe 51 being connected to water channel 15 in mold insert 5, the lower section of horizontal pipe 51 be provided with
It is atomized the tilted tube 52 that air flue 16 is connected to, and horizontal pipe 51 and tilted tube 52 are not communicated with.The length side of tilted tube 52
The extended line of upward central axis intersects with the central axis on the length direction of vehicle needle 3.The structure can make gas and water
It comes into full contact with, to guarantee best atomizing spray effect, while can also prevent the gas in the water and atomization air flue 16 in water channel 15
Body directly contacts, and leads to not the case where being discharged since air pressure is excessively high.
As shown in figure 3, the projected area of the cross section of the corresponding turbine 4 of gas hole 22 is less than the corresponding turbine 4 of gas vent 23
The projected area of cross section.The projection of shape of the cross section of the specific corresponding turbine 4 of gas hole 22 is semicircle, and gas vent 23 is right
Answer the projection of shape of the cross section of turbine 4 for circle.The structure can provide the effect of optimal blowing effect and Quick air-discharge
Fruit, makes all gas all act on the blade tip of turbine 4, and the kinetic energy of air maximizes the machinery for being converted into the rotation of turbine 4
Can, and then the torque that is subject to of turbine 4 is improved, to guarantee vehicle needle 3 can be made to generate in the case that 4 revolving speed of turbine is low enough
Cutting force can extend the bearing service life for installing turbine 4, and plain bearing can also be selected to be produced into lower
This.
As shown in figure 4, inner core 12 includes the preceding core 121 being fixedly connected with handle housing 11 and matches with preceding 1211 grafting of core
The rear core 122 closed.Specifically, preceding core 121 is fixed with handle housing 11 by being integrally formed.Wherein preceding core 121 is close to machine
Air blowing road 13 and water channel 15 its end face of protrusion of first 2 side are simultaneously mating with head 2.On the one hand the structure can increase gas
On the other hand close property can prevent the water in water channel 15 from revealing to improve the efficiency that the gas in head 2 is converted into kinetic energy,
To guarantee there is atomized water to spray to vehicle needle 3 always.
As seen in figs. 5-6, rear core 122 is T-type structure, including horizontal part 1221 and vertical portion 1222, on horizontal part 1221
It is provided with air blowing road 13 and exhaust duct 14, water channel 15 and atomization air flue 16 are provided on vertical portion 1222.Afterwards by nearby on core 122
Air blowing road 13, water channel 15 and the atomization air flue 16 of 121 side of core protrude its end face, and mating with preceding core 121.The structure
Not only material can be saved, but also can guarantee air-tightness and prevent the leakage of water, can finally improve atomizing effect.Afterwards on core 122
Exhaust duct 14 is closed channel, and opening 151 is provided with above connector 18.The structure can slow down the speed of exhaust,
And then revolving speed when 4 zero load of turbine in head 2 can be reduced, to reduce noise and extension turbine 4 and for installing whirlpool
The service life of the bearing of wheel 4.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
