Abstract
The utility model discloses a kind of Wind Volume and subtract sound blower fan, comprise housing, in described housing, be provided with fan and motor, described motor comprises the rotating shaft that connects fan, described fan comprises blade, in described housing, be provided with an inner sleeve, inside put with motor and fan corresponding part and form an annular recess, the internal diameter of inner sleeve is first reduced to increase gradually to two ends by annular recess gradually again; The two ends of the described housing flange plate that is respectively threaded, described motor periphery is evenly equipped with guide vane, and the end of guide vane bends to sickleshaped to air-out direction.Inner sleeve increases air output and air output, and recess makes wind when fan is gone out, have larger buffer space, avoids impacting motor and housing and produces noise; Described sickle-shaped guide vane is conducive to collecting of wind, and air-out effect is good, has further increased defeated air quantity; The method of the replaceable different mounting holes of housing connects dish to adapt to different connecting tubes, and connection more closely, firmly, makes the Applicable scope of blower fan wider.
Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of Wind Volume and subtracts sound blower fan.
Background technique
Existing blower fan easily produces inclined to one side wind in defeated wind process, and then causes its efficiency of transmission low, and existing wind-guiding device guiding air quantity is little, wind effect is poor, the inefficiency that causes blower fan, and blower fan wind can impact housing blade and motor and produce noise, also can affect the normal work of blower fan; The flange plate structure of blower fan end is fixed, and cannot realize the connection to different mounting hole pipelines, causes its applicable narrow range.
Model utility content
The utility model is in order to overcome the deficiencies in the prior art, and providing a kind of can be connected from different pipelines, and the Wind Volume that connects close and firm subtracts sound blower fan.
To achieve these goals, the utility model is by the following technical solutions: a kind of Wind Volume subtracts sound blower fan, comprise housing, the left end of described housing is air intake, and the right-hand member of housing is outlet air end, in housing, be provided with fan and motor, motor comprises the rotating shaft that connects fan, and described fan comprises blade, is provided with an inner sleeve in described housing, inside put with motor and fan corresponding part and form an annular recess, the internal diameter of inner sleeve is first reduced to increase gradually to two ends by annular recess gradually again; The two ends of the described housing flange plate that is respectively threaded, described motor periphery is evenly equipped with guide vane, and the end of guide vane bends to sickleshaped to air-out direction.
Further, in the flange plate at described housing two ends, ring surface forms respectively the bulge loop that can block inner sleeve.
Further, ring surface is provided with at least 2 projections that can block inner sleeve in the flange plate at described housing two ends.
Further, described case top two ends are equipped with the convenient handle of installing near flange plate place.
In sum, the utlity model has following advantage: described inner sleeve has increased air output and the air output of blower fan, recess makes wind when fan is gone out, have larger buffer space, avoids impacting motor and housing and produces noise; Described sickle-shaped guide vane is conducive to collecting of wind, and air-out effect is good, has further increased defeated air quantity; The method of the replaceable different mounting holes of housing connects dish to adapt to different connecting tubes, makes the Applicable scope of blower fan wider, connects more tight, firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of Wind Volume subtracts sound blower fan, comprise columnar housing 1, the left end of described housing 1 is air intake 11, the right-hand member of housing 1 is outlet air end 12, in described housing 1, be provided with fan 2 and motor 3, described motor 3 comprises the rotating shaft that connects fan 2, described fan 2 comprises blade 21, in described housing 1, be provided with an inner sleeve 4, the size and shape of inner sleeve 4 all adapts with housing 1, and the internal surface of inner sleeve 4 and motor 3 and fan 2 corresponding parts form an annular recess 5, and the internal diameter of inner sleeve 4 is first reduced to increase gradually to two ends by annular recess 5 gradually again; Described motor 3 is outer has been arranged with guide vane 7, and guide vane is four, and the periphery of uniform and motor, and the end of guide vane 7 bends to sickleshaped to air-out direction; Inner sleeve 4 increases air output and air output, good guiding guiding function has been played to wind in the formed air channel of inner sleeve 4, increased air quantity, annular recess 5 is set, wind has larger buffer space when fan 2 is gone out, then wind can move from outlet air end and discharge along inner sleeve 4 arc inner wall, avoids impacting motor 3 and housing 1 generation noise; Described sickle-shaped guide vane 7 can make wind move along sickleshaped guide vane, and sickle-shaped end is conducive to collecting of wind, and air-out effect is good, has further increased defeated air quantity.The two ends of described housing 1 flange plate 6 that is respectively threaded, flange plate 6 is many groups, and the size of its mounting hole is different, and the method for housing 1 replaceable different mounting holes connects dish to adapt to different connecting tubes, make the Applicable scope of blower fan wider, connect more tight, firm; In order to strengthen sealing effect, on described flange plate 6, be provided with sealing gasket with housing 1 joint.
Concrete, the interior ring surface of flange plate 6 at described housing 1 two ends forms respectively two bulge loops, and this two bulge loop can be arranged in inner sleeve 4 in housing 1, is enclosed within housing mobile in avoiding.And in other embodiments, the interior ring surface of flange plate 6 that also can be arranged in described housing 1 two ends is respectively equipped with 2 projections, projection acting in conjunction on two flange plate 6 can be stuck in inner sleeve 4 in housing 1 firmly, and described projection can also be more than 2 certainly, and its effect reaching is identical.
In order to facilitate the installation and removal of flange plate, described housing 1 top, two ends is provided with the convenient handle 8 of installing near flange plate 6 places, and handle 8 is for being welded in the draw ring on housing 1; When the flange plate of dismounting air intake, handle that can pull-up outlet air end; And during the flange plate of dismounting outlet air end, handle that can pull-up air intake, dismounting is more prone to.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all should belong to the scope of the utility model protection.
