Description
Technical field
The present invention relates in sprayer, to be used for piston-cylinder mechanism to the liquid pressurization.
Background technology
In the past, known have the pistol-like of a being called as miniaturised nebuliser.Spray pistol has container that keeps liquid and the spray cap group that releasably is installed on the top of container.
The spray cap group has opening via the top of container and falls to pipette and nozzle in the container.Be formed with in the inside of spray cap group and the air connectivity hole of the open communication on the top of container and independent and extend to the fluid path of nozzle from the upper end of pipette, dispose check-valve ball at the cardinal extremity of the aforesaid liquid path adjacent with the pipette upper end with air connectivity hole.
The spray cap group maintains piston-cylinder mechanism.One end of the cylinder of bucket cylinder mechanism and midway being connected of aforesaid liquid path.In the cylinder of bucket cylinder mechanism, take in compression helical spring and maintained piston element.Also dispose the handle of the trigger that is equivalent to pistol on the spray cap group, handle can transmit pushing force to piston element.
In pipette, fluid path and the cylinder of spray cap group, be full of liquid during, the top and the base portion that is installed on the spray cap group on container top that keep container with thumb and palm, and use four fingers except thumb to spur handle, come piston element is applied pushing force via handle, compression helical spring is compressed like this, the liquid pressurization in the piston element countercylinder.Because the upper end of pipette is stopped up by the check-valve ball of the cardinal extremity of fluid path, therefore, pressurized liquid overcomes nozzle group valve closes the pushing force of spring and opens nozzle group valve in the nozzle of elongated end of fluid path, sprays to space outerpace from spray orifice.
After pushing force that handle is applied is eliminated, piston element by compression helical spring reset force effect and get back to initial position with handle, thereby the pressure of the liquid in the cylinder is reduced.Because this pressure reduces, the liquid in the container can be by from the pressure pushing of the atmosphere of air connectivity hole and rise in pipette, thereby the check-valve ball of the cardinal extremity of aforesaid liquid path is pushed to, and flows in the aforesaid liquid path, is full of cylinder.In addition, simultaneously, the pushing force effect that the nozzle group valve in the nozzle cuts out spring because of nozzle group valve is closed, thereby the spraying from the liquid of spray orifice is stopped.
For the spray pistol of selling on the market,, and need provide the spray amount of multiple handle operation and from the sprayer that varies in size of the liquid particles of nozzle spray according to the difference of using object.And the cylinder in above-mentioned spray amount and the piston-cylinder mechanism and the size of piston element have much relations.Promptly, in order to increase above-mentioned spray amount, with regard to the action volume of the piston element in the needs increase cylinder bores.And if reduce the size of liquid particles and dwindle the diameter of spray orifice, then just need to improve piston in the cylinder bores to the plus-pressure of liquid, need make cylinder bores and piston reduced separately.The increase of above-mentioned action volume can cause the displacement of the piston element in the cylinder bores to increase, and/or cylinder bores and piston element diameter increase separately.Yet the displacement of piston element is subjected to the influence of opereating specification of handle very big, is difficult to increase above-mentioned displacement.Therefore, normally increase above-mentioned action volume by the diameter that increases piston element.
Therefore, the producer of spray pistol has made the multiple different spray cap group of having only in the piston-cylinder mechanism of cylinder bores diameter.In addition, also made the piston element of the various diameters corresponding with the cylinder bores of various diameters.The complex structure of spray cap group, it is also very complicated and price is very high to utilize synthetic resin to make the necessary mould of spray cap group.And, in order to make above-mentioned multiple spray cap group, and have no alternative but prepare the mould of multiple high price.
The spray cap group is formed by synthetic resin, and therefore, the cylinder and the piston element of piston-cylinder mechanism are also formed by synthetic resin.The synthetic resin that forms the cylinder of piston-cylinder mechanism and piston element can be because of the kind of the liquid of the spraying kind difference of volume for example, and the swelling along with the growth of service time of sprayer.Cylinder and piston element swelling meeting cause their dimensional accuracy to reduce, thereby can cause liquid to spill from piston-cylinder mechanism, also can make the mobile change difficulty of piston in casing bore.
In order to prevent the mobile situation of difficult casing bore that reduction caused from piston-cylinder mechanism leakage and piston because of the caused dimensional accuracy of swelling of cylinder and piston element, by metal cylinder is embedded cylinder, and the relative metal cylinder of piston element is slided, this speciallys permit in No. 3708002 on the books in Japan.
Metal cylinder is being embedded under the situation of cylinder, also can be rotten because of the different metal cylinder that cause of the kind of the liquid of the kind of the metal material that forms metal cylinder and spraying.Therefore, need will be not can not embed in the cylinder because of the metal cylinder of the rotten metal material of the difference of the kind of the liquid of spraying.
The present invention In view of the foregoing makes, the object of the present invention is to provide following bucket cylinder mechanism, its only need to prepare a kind of spray cap group just can realize the spraying of size of various spray amount or various liquid particles and liquid pressurization easily, make assembling easily.
