Embodiment

For making the utility model clear and definite more full and accurate, enumerate preferred embodiment now and cooperate following diagram, structure of the present utility model and technical characteristics thereof are described in detail as the back:

Please refer to shown in Fig. 1-3, it is respectively the utility model one embodiment's three-dimensional combination figure, three-dimensional exploded view and partial sectional view, the utility model blower 1 is to comprise a cylindrical housing 10, centre on the front-end face 11 of described shell 10 is provided with a wind inlet 12, on one week circle side 13, an exhaust outlet 14 being set again, and the caliber size of described exhaust outlet 14 is to cooperate the bore of a tapering type nozzle 80 and set up; Described again wind inlet 12 places are covered with a filter protection net 30; utilize a ring-like plate 20 to be fitted in the outer side surface of filter protection net 30; and it is relative sealed with the front-end face 11 of shell 10; described filter protection net 30 can hexsteel or grid-like stainless steel spot welding net make; to prevent that foreign matter from entering in the blower 1, protect effect and form.

Wind inlet 12 inboards are connected air-ducting ring 40 again, described air-ducting ring 40 is disc funnel-like bodies, and be provided with bell inlet 41, the inboard of the bell of air-ducting ring 40 inlet 41 is provided with a hypsokinesis air-foiled impeller 50 again, and the bell of described air-ducting ring 40 inlet 41 is to be set in the peristoma of arcuation funnel form air sucking mouth 51 of described hypsokinesis air-foiled impeller 50, make described bell inlet 41 stretch into a segment distance in the peristoma limit of arcuation funnel form air sucking mouth 51 of impeller 50, make between bell inlet 41 and the air sucking mouth 51 and form a bit of overlap region, it is more smooth and easy so can to make air-flow enter impeller 50, and the air-flow that is sucked by air-ducting ring 40 all enters in the impeller 50, and can outwards not release by the space between impeller 50 air sucking mouths 51 and the air-ducting ring 40 bells inlet 41, to increase fan efficiency.Described again hypsokinesis air-foiled impeller 50 is meant that its blade 52 is the air-foiled moulding, the cross section that is described blade 52 is that shape as a wing cross section (Aerofoil-section) is shown in Fig. 2,3, have the thin and streamline Blade Design of intermediate section broad of two tail ends, and so design can increase the fan efficiency of impeller 50; Described again hypsokinesis air-foiled impeller 50 is to rely on a motor 70 to drive, described motor 70 be arranged on impeller 50 centers and with impeller 50 same running shafts; Described motor 70 is to lock in the central position of end plate 60 outer side surfaces, and described end plate 60 ear end face 15 lockings of opposite shell 10 again engages, and operation is maintained in assembling and the dismounting of using the screw closure Placement to be beneficial to described blower 1.
