The specific embodiment

Embodiment: as Figure 1-3, the utility model provides a kind of specific embodiment of Wet-dry dust catcher of tool guiding gutter, it comprises the dirt tube 1 for one-level whirlwind and upper end open, be arranged on the filtering screen 2 in the dirt tube 1, be set in the filter assemblies 3 in the filtering screen 2, be arranged on filter assemblies 3 downstreams and have the motor base 4 on float hurdle 40, be arranged on the float 5 in the float hurdle 40, be arranged on the motor 6 on the motor base 4, and be arranged on draining valve 7 in the filter assemblies 3, float hurdle 40 at least part of being inserted in the filtering screen 2 of motor base 5 wherein, to reduce the complete machine height, and make the internal gas flow passage more compact, reduce wind loss.Float 5 is preferably ball float.

Dirt tube 1 is cylinder barrel shaped and convenient mobile, and height is greater than its diameter, and wherein dirt tube 1 includes and allows air inlet 10 that dust catcher master suction pipe passes and be connected with air inlet 10 and be used for accommodating the dirt tube chamber 12 of filtering screen 2.

Filtering screen 2 is a removable body member, it comprises the base portion 20 that fixes with motor base 4, by extending downwards and the filter house 22 of some mesh is arranged and by filter house 22 bottoms and the cover portion 24 that extends radially outwardly, wherein filter house 22 inside have a cavity 220 in base portion 20 bottoms.The sectional area of base portion 20 is greater than the sectional area of filter house 20, and less than cover portion 22 maximum secting areas.

Filter assemblies 3 comprises that the four sides is around linking to each other and the filter 30 of inner hollow and be used for supporting filter 30 and the brace table 32 of inner chamber 320 is arranged, the sectional area of its middle filtrator 30 is greater than the sectional area of inner chamber 320, and brace table 32 parts are inserted in the cavity 220 of filtering screen 2.Filter 30 is preferably extra large handkerchief structure.

Motor base 4 comprises float hurdle 40 and is one-body molded and be used for installing the platform 41 that there is motor fresh air inlet 410 at motor 6 and center with float hurdle 40.Float hurdle 40 comprises gap 44 that several circumferential spaced railings 42, adjacent handrails 42 formed and be used for air-flow at interval and pass through, be positioned at the bottom and with railing 42 radially spaced partition walls 46 be formed on the partition wall 46 and at least one guiding gutter 48 that is connected with float cavity 460.The annular that its mid-board 46 connects for integral type joins end to end, height be greater than the height of float 5, and innerly be provided with the float cavity 460 of accommodating float 5, covers float 5 thus, with prevent air-flow from around scurry into the bottom of float 5.In like manner partition wall can be some segmental arcs that circumferencial direction links to each other at interval, and forms a guiding gutter between the two adjacent segmental arcs, and segmental arc and railing 42 are crisscross arranged to stop from the gap 44 air-flow.Guiding gutter 48 directly 44 does not arrange towards the gap, but the railing 42 that is interlocked covers, and namely the center line of guiding gutter 48 does not pass gap 44 but passes railing 42, causes float 5 come-ups in order to avoid the air-flow in gap 44 directly rushes at guiding gutter 48.For strengthening the intensity of railing 42, each railing 42 inboard further is provided with a convex tendon that links to each other with partition wall 46.

During work, owing in the upstream of filter assemblies 3 filtering screen 2 has been installed, make the dust that sucks carry out primary separation by filtering screen 2, guarantee that most of dust has been filtered, make the dust that is attached at last on the filter 30 significantly reduce, thereby improve the service time of filter 30, reduce the cleaning frequency of filter 30.Because making, motor suction draining valve 7 sealing osculums can not leak out and leak at this moment simultaneously.When in case the addle in the dirt tube 1 reaches a certain amount of, force the motor fresh air inlet 410 of float 5 risings and sealing motor 6, to quit work, this moment is owing to the gravity of water in self gravitation and the inner chamber 320, make draining valve 7 open osculum, the water that inner chamber 320 accumulates flow in the dirt tube chamber 12 through the mesh of filter house 22 downwards naturally.

Because filtering screen 2 is demountable structure, after filtering screen 2 is dismantled, be Wet-dry dust catcher commonly used from the utility model structure in addition, realize thus exchanging, also make things convenient for the user to select.

Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spiritual essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
