Abstract
This utility model relates to a kind of dental unit foot control return-air silencing means, belongs to manufacture technology field of medical appliance.Its technical characteristics is to be fixed with microswitch on master control air valve, and microswitch is electrically connected by on-off circuit and electromagnetic valve, on the return-air hole of described electromagnetic valve, is provided with silencing means.Make therapy apparatus pipeline return-air in controllable state, and utilize silencing means to eliminate return-air sound.This utility model is simple in structure, and manufacturing cost is lower, very easy to use, can reduce well the noise that while especially cleaning one's teeth in department of stomatology clinic diagnosis process, foot control return-air produces.
Description
Technical field
When this utility model relates to a kind of department of stomatology clinical diagnosis and treatment, eliminate the electromechanical device of foot control return-air sound, specifically a kind of dental unit foot control return-air silencing means, belongs to manufacture technology field of medical appliance.
Background technology
The normal work of the high low speed mobile phone that dental treating chair uses and tooth-cleaning machine and end are unclamped foot control in a flash, because most of residual air in pipeline needs discharge rapidly via foot control immediately, can produce certain noise.Existing foot control is by mechanical valve control, and its master control air valve gas returning port is open type, and silencing means cannot be installed, and can not control effectively to return-air, makes it can only freely enter atmosphere, and it is ear-piercing that consequent noise especially seems in quiet Dental office.
Utility model content
This utility model is exactly a kind of new technical scheme proposing in order to solve existing dental unit foot control return-air sound greatly.
For achieving the above object, this utility model can be realized by following scheme:
A kind of dental unit foot control return-air silencing means, it is on pedal, to be provided with master control air valve, on master control air valve, be fixed with microswitch, microswitch is electrically connected by on-off circuit and electromagnetic valve, on the return-air hole of described electromagnetic valve, is provided with silencing means.
On the base of master control air valve, be installed with microswitch, electromagnetic valve is three-port structure, adds silencing means at its gas returning port place.
The advantage that this utility model compared with prior art had is: simple in structure, easy for installation, cheap for manufacturing cost, when use, noise is very low.
Brief description of the drawings
Accompanying drawing is a kind of example structure composition of this utility model schematic diagram.
Detailed description of the invention
Now with specific embodiment, this utility model is described in further detail by reference to the accompanying drawings:
A kind of dental unit foot control return-air silencing means, it is that peace is installed with microswitch 2 on the base of the master control air valve 1 of foot control, the electromagnetic valve 5 being provided with in main box is three-port structures, microswitch 2 is electrically connected with electromagnetic valve 5 by the on-off circuit 3 on dental unit, the electromagnetic valve 5 that work gas in dental care machine is changed in main box by mechanical valve control in foot control is controlled, and on the steam vent of electromagnetic valve 5, make to be provided with silencing means 4 and return-air is reached can control, can noise reduction object thereby reach.Microswitch 2 closures while pushing down on the pedal, are controlled and are made electromagnetic valve 5 produce action by on-off circuit 3, and work gas is supplied with therapy apparatus air motor to gas outlet through air inlet.In the time of air motor end-of-job, unclamp pedal, gas outlet and gas returning port are connected, and the silencing means 4 that in pipeline, residual air is installed via exhaust ports enters in atmosphere.Change the main valve position 1 in foot control into electromagnetic valve 4 and control, thus reach can noise reduction object.
Master control air valve 1, microswitch 2, pedal can be installed in foot control, electromagnetic valve 4, silencing means 4, air inlet, gas outlet and air vent are installed in therapy apparatus main box.By the silencing means 4 of installing on the air vent in electromagnetic valve 4, return-air sound is carried out to noise reduction, reach the object that reduces noise.
Microswitch 2 is installed on the position of master control air valve 1 in foot control, control its folding by pedal, electromagnetic valve 5 is installed on therapy apparatus main box inside, by the on-off circuit 3 in dental unit internal control circuit, the two is connected, work gas no longer enters in foot control, but send via electromagnetic valve 5, sent the folding of signal of telecommunication control electromagnetic valve 5 by microswitch 2.Its principle is foot control master control air valve 1 to be replaced by the electromagnetic valve 5 of being controlled by microswitch 2 carry out switch gas circuit, pushes down on the pedal, and electromagnetic valve 5 is opened, work gas is logical, unclamps pedal, and electromagnetic valve 5 closes, by electromagnetic valve 5 return-airs, by electromagnetic valve 5 install silencing means 4 by reducing noise.
Claims (2)
1. a dental unit foot control return-air silencing means, it is on pedal, to be provided with master control air valve, it is characterized in that: on master control air valve (1), be fixed with microswitch (2), microswitch (2) is electrically connected by on-off circuit (3) and electromagnetic valve (5), on the return-air hole of described electromagnetic valve (5), is provided with silencing means (4).
2. a kind of dental unit foot control return-air silencing means according to claim 1, it is characterized in that: on the base of master control air valve (1), be installed with microswitch (2), electromagnetic valve (5) is three-port structure, adds silencing means at its gas returning port place.
