Abstract
Abstract A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air, comprising an air inlet-outlet mechanism with a built-up radiator cisterns connected therebelow, having an air diffusion mechanism and an air filtering mechanism set therein to communicate with the air intake conduit so as to provide initial cooling and filtering effect; an exhausting device being made on the bottom of said air filtering mechanism to produce spiral air flow so as to dehumidfy the compressed air; the dehumidified air being to soar upward to pass through said filtering mechanism and the interlocking holes of the flange of said air diffusion mechanism to further be squeezed and diffused to cool down again; said air current being further to pass through said upwardly disposed filtering cylinder for secondary filtration; a water cooling effect being achieved by means of the arrangement of water inlet and outlet on said radiator cisterns to match the communicating pipe formed by the vertical conduits of said radiator cisterns.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
306 words
A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air comprising an air inlet-outlet mechanism, an air diffusion mechanism, an air filtering mechanism, an air exhausting device, an air filtering cylinder and a plurality of radiator cisterns, wherein said radiator cisterns are vertically connected with one another and set below said air inlet-outlet mechanism, having a centrally disposed bore hole to communicate with one another, the first bottom cistern having an enclosed bottom end and a centrally disposed automatic drain valve on the bottom for drainge of water; said air filtering cylinder being secured with said air inlet-outlet mechanism at the bottom there of and being covered with a glass hood to induce filtrated air from said air filtering cylinder toward the air outlet of said air inlet-outlet mechanism; said air diffusion mechanism, air filtering mechanism and an exhausting device being downwardly connected together in proper order by means of series connection to form an assembly, said assembly being further set in the centrally disposed hollow space of said radiator cisterns and attached to the bottom end of an air intake conduit of said air inlet-outlet mechanism by means of said diffusion mechanism through screw joint; said apparatus being characterized in that a double-cooling effect is achieved by means of the double-squeezing and diffusing process through the arrangement of a plurality of air induction slots made in said air diffusion mechanism and a plurality of interlocking holes made on the flanges of the radiator fins of said air filtering mechanism; an air dehumidifying effect being achieved by means of the formation of spiral air flow through the arrangement of a spiral groove made on the water wall of said exhausting device; a water cooling effect being achieved by means of the arrangement of comunicating pipe formed among said radiator cisterns matching with its water inlet and water outlet.
Claim 2
Dependent Claim
306 words
A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air comprising an air inlet-outlet mechanism, an air diffusion mechanism, an air filtering mechanism, an air exhausting device, an air filtering cylinder and a plurality of radiator cisterns, wherein said radiator cisterns are vertically connected with one another and set below said air inlet-outlet mechanism, having a centrally disposed bore hole to communicate with one another, the first bottom cistern having an enclosed bottom end and a centrally disposed automatic drain valve on the bottom for drainge of water; said air filtering cylinder being secured with said air inlet-outlet mechanism at the bottom there of and being covered with a glass hood to induce filtrated air from said air filtering cylinder toward the air outlet of said air inlet-outlet mechanism; said air diffusion mechanism, air filtering mechanism and an exhausting device being downwardly connected together in proper order by means of series connection to form an assembly, said assembly being further set in the centrally disposed hollow space of said radiator cisterns and attached to the bottom end of an air intake conduit of said air inlet-outlet mechanism by means of said diffusion mechanism through screw joint; said apparatus being characterized in that a double-cooling effect is achieved by means of the double-squeezing and diffusing process through the arrangement of a plurality of air induction slots made in said air diffusion mechanism and a plurality of interlocking holes made on the flanges of the radiator fins of said air filtering mechanism; an air dehumidifying effect being achieved by means of the formation of spiral air flow through the arrangement of a spiral groove made on the water wall of said exhausting device; a water cooling effect being achieved by means of the arrangement of comunicating pipe formed among said radiator cisterns matching with its water inlet and water outlet.
Claim 3
Dependent Claim
310 words
A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air according as in claim 1, wherein said air diffusion mechanism includes a hollow head portion, a plurality of air diffusion elements, a fixing screw rod and a plurality of circular blocks having a radiator flange; said hollow head portion including a radially disposed flange around the center, an upper out-threaded fixing end and a lower out-threaded fixing end respectively disposed above and below said flange for connection by screw joint with said air intake conduit and said first circular block respectively, and said lower out-threaded fixing end being arranged to provide a slanting inner wall; said air diffusion elements having a hollow structure, comprising a reduced upper flange and a reduced inner bottom, said reduced upper flange including a radially disposed plurality of air induction slots communicating with the inner wall of said corresponding element at the top end and with the outer wall of said corresponding element at the lower end to match the enclosed bottom of the bottom element so as to let compressed air be induced into the hollow space of said elements and squeezed out of said elements through said induction slots to further be radially diffused outward; said elements being connected together and screwed up with the top fixing plate of said head portion by means of a screw rod; said circular blocks including a radiator flange, an inner or outer threaded circular upper end and an inner or outer threaded circular lower end to let said circular blocks be screwed up with one another; at the time said circular blocks being connected together by means of series connection the connected blocks being further attached to said head portion to let the connected elements be disposed inside said circular blocks; a plurality of circumferentially disposed interlocking holes being made on the radiator flanges of said radiator fins.
Claim 4
Dependent Claim
134 words
A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air as in claim 1, wherein said air filtering mechanism includes an inner threaded head portion, a filtering cylinder and a plurality of circular blocks having a structure same as the said circular blocks of said air diffusion mechanism, said inner threaded head portion being screwed up with the bottom end of said air diffusion mechanism at the top and connected with said circular blocks at the bottom; said filtering cylinder including a bottom disc to bolck up its bottom end and being connected to said head portion at the bottom by means of said screw rod axially penetrating through the central portion of said bottom disc so as to let the diffusion air from the upper air diffusison mechanism be initially filtrated through said filtering cylinder.
Claim 5
Dependent Claim
114 words
A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air as in claim 1, wherein said exhausting device being provided to screw up with the first bottom piece of said circular blocks of said air filtering mechanism, comprised of a annular head portion having a horn-shaped bottom end to define an upwardly expanded central hole for setting therein of a cone block having a spiral groove on its outer wall to let the air current from said filtering mechanism be exhausted through said exhausting device to form spiral air flow for drying process; said exhausting device also including a plurality of piercing holes on its horn-shaped bottom end for the exhausted air to upwardly penetrate therethrough.
