The wind wheel part and the motor part of the fan can be conveniently and quickly maintained, repaired, inspected, cleaned and the like under the condition that the outer casing does not need to be dismounted, thereby being capable of effectively improving working efficiency and reducing burden of workers.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of openable blower fan.
Background technique
Blower fan is a kind of common device that is used for exhausting smoke evacuation, ventilation, and the application of blower fan is all arranged in the place that needs such as manufacturing shop, coating-spraying environment, laboratory, kitchen, hotel, building in time ventilate.Common blower fan comprises the constituent elements such as shell, blower fan wind wheel and motor with inlets and putlets of ventilation.The driven by motor wind wheel rotates, and flows thereby air is produced, and in the intake grill entering blower fan of blower fan, discharges from exhaust outlet again.Can select the intake grill of blower fan and the mounting type of exhaust outlet according to actual needs, realize indoor exhausting or air-supply.
The shell of this blower fan is in order to guarantee the exhausting effect; Generally all be designed to integrated type; Its installation and removal are cumbersome, especially in use need partly carry out maintaining to wind wheel, repair clean and during operation such as safety inspection, pull down whole casing and just can carry out.Because the volume of shell own is big, and is connected with the pipeline of upstream and downstream, its dismounting is pretty troublesome, not only require technical merit high to the attendant, and workload is also big.Therefore, need to occur a kind ofly being convenient to safeguard, the blower fan of safety check and repairing.
The model utility content
The utility model is in order to overcome above-mentioned defective of the prior art, a kind of openable blower fan to be provided.Staff's burden can be effectively increased work efficiency, alleviated in operations such as the wind wheel of this blower fan and motor part can be safeguarded under the situation that need not dismantle shell quickly and easily, repairing, safety check and cleaning.
For realizing above-mentioned purpose, the openly following technological scheme of the utility model:
A kind of openable blower fan; Comprise shell, motor and wind wheel; Also comprise the cover plate that flexibly connects with said shell; Said wind wheel is arranged on the side of this cover plate towards the blower fan cavity, and said motor is installed in the opposite side of this cover plate, and the output terminal of motor shaft passes this cover plate and is connected with said wind wheel.
Further, said shell comprises front side plate, reverse side side plate and the spiral case that is connected said positive and negative side plate, and wherein, said front side plate is provided with and is used to connect the fixed support of said cover plate and the through hole that matches with said cover plate; Have intake grill on the said reverse side side plate.
Further, also be fixedly connected with at least one movable support on the said cover plate, this movable support and said fixed support flexibly connect.Preferably, said fixed support and said movable support link together through screw.
Further, be provided with seal ring between said cover plate and the said shell.
Compared with prior art, the utlity model has following beneficial effect:
1, cover plate and front side plate flexibly connect, and when proper functioning, cover plate and front side plate are fit together, and tighten with screw and to get final product; When needing maintenance, repairing or safety check; Can unclamp screw; Open cover plate, thereby the wind wheel of blower fan is exposed from cavity, and need not carry out any dismounting the housing and the external pipe of blower fan; Easy-to-operat, and can avoid degradation defective under the device damage that dismounting caused, installation precision to Blower Housing and external pipe.
2, cover plate is provided with seal ring with the position that the front side plate matches, and the blower fan cavity when making work can not leak out.
Description of drawings
Fig. 1 is the front view of the wind wheel full open position of the utility model;
Fig. 2 is the front view of the semi-open state of wind wheel of the utility model;
Fig. 3 is the wind wheel front view of open mode not of the utility model.
In conjunction with the accompanying drawing following reference character of mark above that:
The 1-spiral case, 2-front side plate, 3-reverse side side plate, 4-fixed support, the movable support of 5-, 6-motor, 7-cover plate, 8-wind wheel, 9-screw, 10-intake grill, 11-exhaust outlet.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
A kind of openable blower fan; Shown in Fig. 1 to 3; Comprise shell, motor 6 and wind wheel 8, also comprise the cover plate 7 that flexibly connects with said shell, said wind wheel 8 is arranged on the side of this cover plate 7 towards the blower fan cavity; Said motor 6 is installed in the opposite side of this cover plate 7, and the output terminal of motor shaft passes this cover plate 7 and is connected with said wind wheel 8.Said shell comprises front side plate 2, reverse side side plate 3 and is connected the spiral case 1 of said positive and negative side plate 2,3.Wherein, Said front side plate 2 is provided with and is used to connect the fixed support 4 of said cover plate 7 and the through hole that matches with said cover plate 7; The diameter of this through hole is slightly less than the diameter of cover plate 7; Thereby assurance wind wheel 8 can not be run on the front side plate 2 when folding cover plate 7, and the edge of cover plate 7 can also be pressed on this through hole side plate on every side.Have intake grill 10 on the said reverse side side plate 3.On shell, also be provided with exhaust outlet 12.Be fixedly connected with a movable support 5 on the said cover plate 7, this movable support 5 links together through screw 9 with said fixed support 4.Be provided with seal ring (not shown) between said cover plate 7 and the said front side plate 2, can not produce during with assurance work and leak out in the edge of cover plate 7.
During work, cover plate 7 is closed, as shown in Figure 3.At this moment; Tightening the screw 9, make between movable support 5 and the fixed support 4 fastening, simultaneously; Can also strengthen fastening with screw or pressing plate in the junction of cover plate 7 and front side plate 2; So that wind wheel 8 rotates under the drive of motor 6, air is sucked from intake grill 10, discharge from exhaust outlet 12 again.
When needs repairing, safety check are perhaps safeguarded; The cover plate 7 of blower fan is unclamped with front side plate 2, open cover plate 7 then, shown in Fig. 2 and 3; Wind wheel 8 is exposed from the cavity of blower fan; Avoided spiral case 1, front side plate 2, reverse side side plate 3 that has fixed and the external pipe (not shown) that links to each other with inlets and putlets of ventilation 10,11 are dismantled, can greatly reduce staff's working strength and workload, increased work efficiency.
More than the disclosed more excellent specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
