Abstract
The invention provides a gas source passage selection switch. The switch comprises a valve which is provided with an internal chamber. A gas inlet, a first gas outlet and a second gas outlet are formed in one side of the internal chamber, wherein the gas inlet is communicated with the internal chamber, and the first gas outlet and the second gas outlet are disposed in two sides of the gas inlet and communicated with the internal chamber. A valve spool capable of moving in the internal chamber is arranged in the internal chamber and comprises a first valve spool body and a second valve spool body, and a lever for driving the valve spool to move is arranged on one side of the second valve spool body. The gas source passage selection switch is simple in structure, low in cost, convenient to mount and capable of facilitating passage switching during gas blow-out for medical workers.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of source of the gas and select way switch.
Background technique
Along with the raising day by day of national economy and living standard, people occur that the probability of oral problem is more and more higher, and meanwhile oral hygiene and oral health more and more are subject to people's attention.At present, the doctor, in using the dental therapeutic tool working procedure, usually needs to use and treats relevant air-flow and carry out completing of auxiliary curing, such as dry oral cavity etc.But, in existing apparatus, while needing to change the passage of gas ejection, toward contact, can't realize.
In view of this, be necessary to propose a kind of source of the gas that overcomes the problems referred to above and select way switch.
Summary of the invention
The object of the present invention is to provide a kind of source of the gas to select way switch.
For achieving the above object, a kind of source of the gas of the present invention is selected way switch, and it comprises:
Valve body, described valve body has internal chamber, the first air outlet be connected with described internal chamber, the second air outlet that one side of described internal chamber is provided with the suction port be connected with described internal chamber and is positioned at the suction port both sides, be provided with the spool that can move therein in described internal chamber, described spool comprises the first spool and the second spool, and a side of described the second spool is provided with the spanner that drives described valve core movement.
As a further improvement on the present invention, described the second spool closes on described spanner one end and is provided with bearing plate, and described bearing plate and described spanner lean.
As a further improvement on the present invention, described valve body also has second chamber adjacent with described internal chamber, described bearing plate, and part be arranged in described the second chamber.
As a further improvement on the present invention, the interface place of described internal chamber and the second chamber is formed with annular groove, is provided with the spring offseted with described bearing plate in the groove of described annular.
As a further improvement on the present invention, described spanner is movably connected on described valve body by fixing pin.
Compared with prior art, the invention has the beneficial effects as follows: it is simple in structure that source of the gas of the present invention is selected way switch, with low cost, easy for installation, the passage in the time of can making medical care personnel switch easily the gas ejection.
The accompanying drawing explanation
Fig. 1 is the plan cross-section schematic diagram that source of the gas of the present invention is selected an embodiment of way switch.
Embodiment
Below in conjunction with each mode of execution shown in the drawings, the present invention is described in detail; but should be noted that; these mode of executions are not limitation of the present invention; those of ordinary skills are according to these mode of execution institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection scope of the present invention.
As shown in Figure 1, source of the gas of the present invention is selected way switch 100 and is comprised valve body 10, this valve body 10 has internal chamber 101, and a side of internal chamber 101 is provided with coupled logical suction port 20, the both sides of suction port 20 are respectively arranged with the first air outlet 30 of being connected with internal chamber 101, and the second air outlet 40.Also be provided with spool 50 in above-mentioned internal chamber 10, this spool 50 specifically comprises the first spool 501 and the second spool 502, is provided with the O type circle of sealing use between the two.Above-mentioned spool 50 can be slided along internal chamber 101, in order to provide, is the active force that spool 50 slides, and with above-mentioned the second spool 502 1 sides, is provided with the spanner 60 that drives described spool 50 motions.This spanner 60 is flexibly connected by fixing pin and valve body, and can above-mentioned fixing pin be that rotating shaft is rotated.
Further, valve body 10 also has second chamber 102 adjacent with internal chamber 101, and this second chamber 102 is served as reasons from extended the convexing to form of internal chamber 101 1 side margin.Described bearing plate, and part spanner 60 be arranged in described the second chamber 102.The end that above-mentioned the second spool 502 closes on above-mentioned spanner 60 is provided with bearing plate 51, and itself and above-mentioned spanner 60 lean.Thereby, when rotating spanner 60,60 pairs of bearing plates 51 of spanner apply an active force, bearing plate 51 further band movable valve plug 50 moves.The interface place of above-mentioned internal chamber 101 and the second chamber 102 is formed with annular groove, is provided with the spring offseted with described bearing plate in the groove of described annular.Thereby, when spanner 60 returns to initial position, spool 50 can, under the driving of the elastic force of spring, also be got back to initial position.
Thereby, when not pulling spanner, the gas entered from suction port, give vent to anger from the first air outlet, after rotary spanner, spool moves thereupon, and the first air outlet is closed, and the second air outlet is for spraying gas.
It is simple in structure that source of the gas of the present invention is selected way switch, with low cost, easy for installation, the passage in the time of can making medical care personnel switch easily the gas ejection.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.Any reference character in claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
