Description
Technical field
The present invention relates to a kind of dental treatment electro-motor, relate to the dental treatment equipment.
Background technology
The dental drill machine (also claiming dental handpiece) that odontologist uses comprises the mechanical, electrical moving dental drill machine of high speed turbine dental drill.Wherein electromotive dental drill mainly is made up of electro-motor, head, drill point, water system, air supply system, illuminator.Its work is mainly by electrical motor driven, drives treatment operations such as the car pin bores, mills, mill, throwing.
Electro-motor places the handle portion of dental drill, and it is too big that external diameter can not be done, otherwise profile is big, Heavy Weight, and the doctor holds not firm.Because the increase of mobile phone electro-motor diameter is restricted, the existing electro-motor underpower that often seems, when doctor's over-loading operation, the motor speed decay is serious; Over loading works long hours, and motor temperature raises, even scalds one's hand.So, electrical machinery life reduces, and fault increases.
During treatment operations such as the car pin bores on tooth, mills, mill, throwing, cleanings of must spraying water of its cutting face, cooling is cleaned for simultaneously the car pin and is cooled off.Binding one water supply line outside handset that existing method of supplying water has, handset structure is loose like this, and the bodily form increases, and globality is bad, operating difficulties.The water and gas conduit that has places within the mobile phone shell, and outside the motor, this will take pipeline by the space, and phenolphthalein is sent a telegraph the machine diameter and must be reduced thereafter, causes the power of motor deficiency.
When the car pin cuts on tooth, must throw light in its cutting face, so that the doctor in time observes.Now much adopt auxiliary light illumination beyond the mobile phones,, prolonged treatment time, influenced therapeutic effect if, often have the insufficient problem of illumination at treatment backteeth, upper tooth, when the position such as being completely cured.The technology that has provides illuminating lamp lamp line passage for mobile phone, but places within the mobile phone shell, and outside the motor, this will take lamp line by the space, and phenolphthalein is sent a telegraph the machine diameter and must be reduced thereafter, causes the power of motor deficiency.
Summary of the invention

The operation principle of water system is: initial from socket 4, water infeeds water pipe 6 by water-aspirator pressure, the socket 4 of flowing through, through hole 12 on electric motor end cap 3, the motor stator lamination 5 arrives water pipe sealing column 7, and " O " shape rubber seal is housed on the water pipe sealing column 7, it puts in to constitute in the closed hole of termination 2 and connects water seal, current are pressed into termination 2 waterway channels through the annular groove of water pipe sealing column 7, are flowed out by termination 2 one side outlets, 10 pressure at last.If the butt joint of dental drill head is inserted into when needing work on the termination 2, hydraulic pressure is input to the dental drill head then, finally by the ejection of head hole for water spraying, the jet mixing on water spray and the head forms atomized water, can guarantee that enough water sources carry out comprehensive cleaning and cooling to car pin and car pin work surface.
The formation of air supply system:
The structure of air supply system is: trachea 8 passages that trachea 8 constitutes through socket 4, electric motor end cap 3, motor stator lamination 5, when termination 2 and motor case 1 fastening, by trachea sealing column 9, termination 2 and trachea 8 are combined, owing on the trachea sealing column 9 " O " shape rubber seal is housed, in gas circuit connects, guarantee that under the situation of air pressure, air-flow can not leak.
The operation principle of air supply system is: initial from socket 4, gas infeeds trachea 8 by air pump pressure, the socket 4 of flowing through, through hole 12 on electric motor end cap 3, the motor stator lamination 5 arrives trachea sealing column 9, and " O " shape rubber seal is housed on the trachea sealing column 9, it puts in to constitute in the closed hole of termination 2 and connects sealing gland, air-flow is pressed into termination 2 gas channels through the annular groove of trachea sealing column 9, is flowed out by 2 one side gas outlets, termination, 11 pressure at last.If the butt joint of dental drill head is inserted into when needing work on the termination 2, air pressure is input to the dental drill head then, finally by head fumarole ejection, the water spray on the jet and head mixes and forms atomized water, can guarantee that enough sources of the gas carry out comprehensive cleaning and cooling to car pin and car pin work surface.
The formation of high pressure xenon gas lamp electric power system:
The structure of high pressure xenon gas lamp electric power system is: connect electric hole post 13 and lug plate 14 each other screw thread be fixed on the both sides up and down of socket 4, because socket 4 is a plastic material, can effectively insulate, two lamp line 15 solderings are on one side of lug plate 14, lamp line 15 passes the access opening 12 of motor stator lamination 5, the other end soldering of lamp line 15 is in interrupt 16 lower end of spring, the spring 16 1 sections interference of interrupting are installed in lamp socket 17 holes, lamp socket 17 is contained in motor case 1 hole 19, hole 19 and lamp socket 17 external cylindrical surface interference fit, fixed, lamp socket 17 is a plastic material, can effectively insulate, what high pressure xenon gas lamp 18 was very stable is inserted on its lamp socket 17.
The operation principle of high pressure xenon gas lamp electric power system is: initial from socket 4; transmission of electricity is via connecing electric hole post 13; socket 4; lug plate 14 is to lamp line 15; lamp line 15 is by passing through in motor stator lamination 5 holes 12; arrive motor case 1; spring in the lamp socket 17 interrupts 16; what high pressure xenon gas lamp 18 was very stable is inserted on the lamp socket 17; on 2 corresponding positions, termination, have the light source delivery outlet; termination 2 is fastened on the seam of motor case 1; owing to have the common shroud of lamp socket hole 19 on the motor case 1 and termination 2 to give 18 1 reliable protection spaces of high pressure xenon gas lamp, make its safe and reliable work.Because high pressure xenon gas lamp 18 power are big, the temperature height, in lamp socket hole 19, the spy has a cooling pore, and air is lowered the temperature to high pressure xenon gas lamp 18 by the cooling hole through motor case 1 inner chamber via the air pump supercharging.When high pressure xenon gas lamp 18 needs to change, can easily extract from light source delivery outlet pincers tweezer, and plug new bulb.If the butt joint of dental drill head is inserted into when needing work on the termination 2, the light source of high pressure xenon gas lamp 18 is transmitted to the fibre bundle on the head, until the bottom of head front end, the leaded light light beam is concentrated, light is sufficient, no matter anywhere the cutwork face of car pin on tooth, can both obtain competent illumination.
