Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described further.
Be the present embodiment motor of dust collector and downstream configurations schematic diagram thereof as Figure 1-4, dust catcher of the present invention comprises motor 1, exhaust air filter 2, switching valve 3 and exhausting plate 4, dust catcher outer gas stream sucks in dust catcher by motor 1, air-flow is along gas channel flowing in dust catcher, and described gas channel refers to air-flow flow path in dust catcher.Described exhaust air filter 2 is positioned at motor 1 downstream, namely the air-flow in dust catcher passes through exhaust air filter 2 by motor 1 behind motor row air port 12, the Main Function of exhaust air filter 2 is by through air-flow that main filtration system (being such as arranged on the filter in vacuum cleaner dust bucket) is filtered, fine solid particle particle filtering particularly by being mingled with in the air-flow after motor falls, thus makes the air-flow of discharge dust catcher cause secondary pollution.Exhaust air filter 2 can be HEPA or sponge.Exhaust air filter 2 downstream is provided with blowing mouth, air outlet and switching valve.Blowing mouth is positioned at the axial direction in motor row air port, namely blowing mouth is on the axis direction of motor row air port, on electrical axis or near electrical axis, be arranged so that the air-out in the wind that blowing mouth blows out and motor row air port is in same direction, decreases the loss of air-flow like this.Described air outlet is positioned at blowing mouth side, and described switching valve 3 is arranged on exhausting plate 4, and dust catcher can be made at blowing state and non-blowing state auto-switching.Described exhausting plate 4 is one piece of dismountable cover plate at motor of dust collector exhaust outlet rear portion, and exhausting plate 4 is provided with sidewall 45, and sidewall 45 surrounds wind chamber 46, described wind chamber 46 roughly squarely, and the air-flow after exhaust air filter 2 filters enters wind chamber 46.Described switching valve 3 comprises valve body 31 and an elastic component, and in the present embodiment, described elastic component is spring 32, and described switching valve 3 is positioned at the axial direction in motor row air port 12.Be provided with spring 32 between valve body 31 and exhausting plate 4, spring 32 makes valve body 31 can automatically reset when drying and non-blowing state switches.Described exhausting plate 4 is provided with blowing mouth 44 and air outlet 41, and described air outlet is located on sidewall 45, and air outlet 41 is the breach on sidewall 45.Described air outlet 41 place axis 410 is perpendicular to electrical axis 10.Described blowing mouth 44 is positioned on electrical axis 10 direction, and namely the air-flow that namely motor row air port 12 is discharged blows out by blowing mouth without conversion direction.Blowing mouth 44 is the through hole connecting vented cavity 46.Described blowing mouth 44 is roughly circular, and be divided into three chambers by rib 47, comprise the first air guide hole 441, second air guide hole 442 and the 3rd air guide hole 443, described valve body 31 is provided with groove 316 and coordinates with rib 47, valve body 31 can be moved in electrical axis direction, and rib 47 pairs of valve bodies 31 play position-limiting action simultaneously, and rib 47 is between butting section 445 and blowing mouth 44 annular wall 444, its one end is fixed in blowing mouth 44 annular wall 444, and the other end is fixed on butting section 445.Described spring 32 is between butting section 445 and valve body 31, and namely spring 32 one end is resisted against on butting section 445, and the other end is resisted against on valve body 31.Described first, second, and third air guide hole is identical air guide hole, and air-flow is imported to blowing mouth 44 by air guide hole.Described exhausting plate 4 is also provided with screen 43, and then air-flow is distributed to outside by screen 43 through air outlet 41, and arranging screen is to have guide effect to the air-flow of discharging.Described valve body 31 is positioned at blowing mouth 44, and valve body comprises the first baffle plate 311, second baffle 312 and third gear plate 313, and described three baffle plates are baffle plates that shape is identical, corresponds respectively to the first air guide hole 441, second air guide hole 442 and the 3rd air guide hole 443.Described valve body 31 also comprises side plate 315, and described side plate 315 in third gear plate 313 side, and is one with third gear plate 313, and the effect of side plate 315 is to open and close air outlet 41.Because side plate 315 and third gear plate 313 are one, therefore the 3rd air guide hole 443 is closed, and be no matter also non-blowing state in blowing state, air-flow all can not flow through the 3rd air guide hole 443.Described spring 32 one end is arranged on butting section 445 place in the middle of blowing mouth 44, valve body 31 is arranged in blowing mouth 44, and Compress Spring 32, snap fit 314 on valve body 31 is stuck in the annular wall 444 of blowing mouth 44, therefore valve body 31 can not be ejected blowing mouth by spring, and valve body 31 can slide in blowing mouth simultaneously.
As the schematic diagram that Fig. 5-7 is the present embodiment dust catchers when non-blowing operation, in figure, the direction of arrow represents air current flow direction.After dust catcher starts, electric machine rotation forms negative pressure in dust catcher, dust catcher outer gas stream enters dust catcher inside by air inlet (not shown), air-flow carries various dust or foul usually, the air-flow entering dust catcher passes through motor after filtering, again filtered out the dust carried in air-flow through exhaust air filter 2 by the air-flow after motor, prevent the air-flow of discharging dust catcher from causing secondary pollution, the air-flow after exhaust air filter 2 filters enters wind chamber 46.When non-blowing state, due to the effect of spring 32 restoring force, snap fit 314 is stuck in annular wall 444, first air guide hole 441, second air guide hole 442 and the 3rd air guide hole 443 block by the first baffle plate 311 of switching valve 3, second baffle 312 and third gear plate 313, air outlet 41 is opened simultaneously, air-flow in wind chamber 46 discharges wind chamber 46 from air outlet 41, and air-flow discharges dust catcher through screen 43 after flowing out from wind chamber 46.When non-blowing state, air-flow is disperseed to discharge dust catcher.
If Fig. 8-10 is the present embodiment dust catcher schematic diagrames when drying operation, when user will utilize dust catcher blowing function, hose coupling of suction cleaner 6 is inserted blowing mouth 44, the tube wall 62 of hose coupling 6 front end promotes switching valve 3, and spring 32 is compressed further until the draw-in groove 48 on exhausting plate 4 engages with the projection 61 on hose coupling 6.Now the first baffle plate 311 of switching valve 3, second baffle 312 and third gear plate 313 are open, side plate 315 is boosted blocks air outlet 41, now the first air guide hole 441 and the second air guide hole 442 are opened, air outlet 41 is closed, air-flow in wind chamber 46 is pooled to blowing mouth 44 by the first air guide hole and the second air guide hole, air-flow in blowing mouth 44 utilizes blowing to sweep through hose coupling 6 by flexible pipe or other accessories, described hose coupling refers to and the joint that flexible pipe one end is connected, for with the Interference fit on dust catcher, hose coupling can be and flexible pipe one or separable joint.
Above-described embodiment is the preferred embodiment of the present invention, blowing and air-out is switched by the switching valve being arranged on motor of dust collector downstream, switching valve is enable automatically to slide and reset by arranging elastic component (spring as in embodiment), do not need user's manual operation switching valve, only need to insert or extract the conversion that hose coupling just can realize blowing or air-out, convenient for users, switching valve structure is simple simultaneously, small volume, low cost of manufacture.
