Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In a kind of, air intake is without blade fan, and comprise dismountable wind-tunnel 2 and main frame 1, wind-tunnel is arranged on the top of main frame.Be provided with control panel in main frame 1, control panel is connected with the knob 3 on panel and display screen 4.Air booster is arranged on the support of main frame inside, and air booster comprises brushless motor and impeller, and its one end is air intlet, and one end is air outlet slit.Selecting of air booster is identical without the air booster in blade fan with existing.
For improving the air-out efficiency without blade fan, intake grill is arranged on the inwall of wind-tunnel by embodiment.Herein using the air supply direction of wind-tunnel and the front of control panel as front, using the air intake direction of wind-tunnel as rear, hereinafter identical.
As shown in Figure 1 to Figure 3, the inwall of wind-tunnel is provided with slot-shaped high pressure outlet air mouth 5, high pressure outlet air mouth 5 is between 1/1 to two/4th of wind-tunnel total length.Relative to the opposite side of exhaust outlet; be provided with suction port 6; suction port 6 is domatic; suction port 6 is provided with filter screen; filter screen is the reticular structure of porous, or the slot-shaped structure of multiple tracks, and it is except the dust in filtered air; reducing large particle dust enters into outside main frame inside, also plays the auxiliary airflow direction changed in wind-tunnel and uses.It makes a small amount of air under effect of inertia, along the surface of filter screen, crosses the domatic of suction port 6 and high pressure outlet air mouth 5, guides the air flowing in wind-tunnel.
Be provided with air inlet internal channel below suction port, be provided with internal channel of giving vent to anger below high pressure outlet air mouth 5, air inlet internal channel communicates through the air intlet of suction tude and air booster, and internal channel of giving vent to anger communicates through the air outlet slit of air outlet tube and air booster.
For simplified structure, be horizontally placed in main frame in embodiment by air booster rotor shaft direction, such air intake pipe 9, air booster 10 and air outlet tube 11 constitute U-shaped structure, and elbow is less, and air-flow is comparatively unobstructed.
In order to the air draught efficiency of suction port is best, ensures that all air draughts all come from the intake grill of wind-tunnel, in embodiment, between suction port and the edge of wind-tunnel, be provided with air guide ring 7.The width of air guide ring is 1cm to 3cm.After air guide ring is set, is equivalent to and suction port has been inside contracted back 1cm to 3cm to wind-tunnel, just sucked by intake grill after only having air to enter wind-tunnel completely, avoid a small amount of air and flow away from the outside of wind-tunnel.
For when realizing sweeping wind, main frame 1 does not turn, only that wind-tunnel rotates, in embodiment, the junction of wind-tunnel and main frame is provided with a guide plate 8 be rotationally connected relative to main frame 1, guide plate is provided with steer motor and steering equipment, and about driving wind-tunnel part, 150 degree of rotations are blown.
For ensureing that air intake road in wind-tunnel and the air booster gone out in wind path and main frame communicate all the time, guide plate 8 is designed to two-layer, and it at the middle and upper levels guide plate is provided with the waist shaped hole 81 of a symmetry, communicates respectively with air inlet internal channel, internal channel of giving vent to anger.The air intake pipe and the air outlet tube that are fixed on the air booster in main frame communicate with this pair waist shaped hole respectively.Lower floor's guide plate is fixedly connected with the air intake pipe 9 of air booster, air outlet tube 11 respectively.
Steer motor is arranged on guide plate center, drives upper strata guide plate and wind-tunnel to rotate.When this structure makes to sweep wind without blade fan, main frame can not be followed wind-tunnel and be rotated, and is only that guide plate drives wind-tunnel to rotate.Therefore the control panel be arranged on main frame can not rotate, and is user-friendly to the knob on main frame and observes display screen.
Core of the present invention is that a kind of air making full use of air intake suction strengthens equipment, it should be pointed out that its using scope is not only confined to without blade fan, also comprises other as on the blast device of the products such as air-conditioning, air cleaner, humidifier.
