Abstract

The utility model discloses a roof electric aspirator, which comprises an air cylinder and a top cover which is located on the upper portion of the air cylinder, wherein a holdfast is installed in the air cylinder, a motor is installed on the holdfast, an exhausting impeller is installed on the shaft of the motor, and a cone air-dispersing device is installed on the top cover. Air flow disperses towards all around along the walls of the cone air-dispersing device when warm air in the room is exhausted to the top cover from bottom to top, which avoids from flowing downwards after obstructed when air flow reaches to the top cover, avoiding the disturbing phenomenon which is caused by the interference of upwards warm air when air flow moves downwards, and reducing dynamic cost. Simultaneously the aspirator fast cools down roof around an air outlet through air which is aspirated, and the cooling effect is accelerated. The roof electric aspirator of the utility model is suitable to be used on steel structure, star sheds and iron sheet plants and the like, can aspirates large amount of warm air, steam, moldy air and dust which are gathered under the irradiating of the sun to the outside, and provides favorable working and storage environment for workers and goods under cold ventilation.

Description

The electronic aspirator of roofing

Technical field

The utility model relates to a kind of roofing aspirator, the electronic aspirator of particularly a kind of structure improved roofing.

Background technology

Present electronic roofing aspirator, its structure is shown in the combination section of Fig. 1, comprise that mainly can be laid an air duct body that is fixed on the roof, above the air duct body, be provided with overhead guard, in the air duct body, be provided with support, establishing a motor body with exhausting leaf in support middle position group makes progress upright, the running of motor body can drain into indoor hot gas outdoor when electric power starting, but its shortcoming is when the motor body turns round, shown in Fig. 1 arrow, being blocked reverse below when indoor hot gas is evacuated to overhead guard from bottom to top flows, hot gas flows and must cause producing interference and disturbing phenomenon taking place with the hot gas that makes progress downwards the time, the effect that causes discharging hot gas is bad, causes the increase of power cost.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of electronic aspirator of roofing low, that result of use is good that consumes energy.

The technical scheme that its technical problem that solves the utility model adopts is:

The electronic aspirator of roofing comprises air duct body and the overhead guard that is positioned at air duct body top, in the air duct body support is installed, and motor is installed on the support, on the axle of motor the exhausting impeller is installed, and the diffusing wind device of a cone also is installed in the described overhead guard.

The beneficial effects of the utility model are: the diffusing wind device of a cone is installed in overhead guard, has changed the direction of air-out.When indoor hot gas is evacuated to overhead guard from bottom to top, air-flow along cone loose the wind wall to around scatter, having avoided the arrival overhead guard to be blocked reverse below flows, produce with the hot gas that makes progress downwards and interfere and the generation disturbing phenomenon, also utilized the wind of extracting out that roofing around the air outlet is cooled off rapidly simultaneously, accelerate the effect of cooling, reduced power cost.The flabellum of extraction fan is a flanging formula flabellum, has increased air quantity, has reduced noise.Advantages such as that the electronic aspirator of roofing of the present utility model also has is stable, leakproof, be applicable to steel construction, Xing Peng, iron sheet factory building etc., can shine upon a large amount of hot gas, steam, stale and the dust assembled down at burning sun extracts out outside the room rapidly, and the air-flow that makes full use of extraction cools off near roofing rapidly, can work under refrigerant ventilation and the environment that provides is provided to workman and goods.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is present aspirator air-flow schematic diagram;

Fig. 2 is the utility model aspirator air-flow schematic diagram;

Fig. 3 is the three-dimensional broken away view of the utility model;

Fig. 4 is the utility model profile.

The specific embodiment

With reference to Fig. 2, Fig. 3, Fig. 4, the electronic aspirator of roofing, comprise the overhead guard 1 that is installed on air duct body 3 and is installed on air duct body 3 tops, support 9 is installed in the air duct body 3, motor 8 is installed on the support 9, on the axle of motor 8 exhausting impeller 7 is installed, the diffusing wind device 2 of a cone also is installed in the described overhead guard 1.

Cone in the utility model overhead guard 1 wind device that looses has changed the direction of air-out.When indoor hot gas is evacuated to overhead guard from bottom to top, air-flow along cone loose the wind wall to around scatter, avoided the arrival overhead guard to be blocked reverse below and flowed, produce with the hot gas that makes progress downwards and interfere and the generation disturbing phenomenon.

Air duct body 3 is installed on the roof 10 by collection air port 4, splash guard 20 and bracing frame 21.

The edge and the overhead guard 1 of the diffusing wind device 2 of cone are provided with the through hole that matches, and the diffusing wind device 2 of cone is installed on the overhead guard 1 by bolt 11, can certainly adopt additive method as being welded on the overhead guard 1.Collect air port 4 and be fixed on the air duct body 3, can adjust according to the roofing gradient during installation by bolt.Be provided with the through hole that matches with overhead guard 2 on the air duct body 3, overhead guard 1 is fixed on the air duct body 3 by support column 5.

Exhausting impeller 7 is flanging formula impellers, can shine upon a large amount of hot gas, steam, stale and the dust assembled down at burning sun and extract out outside the room rapidly.

Bracing frame 21 is provided with anti-fall net 22, falls within doors with the object that prevents the roof, causes unnecessary trouble.

In addition, overhead guard 1 edge is provided with Rain-proof skirt 23 and splash guard 20, has prevented that rainwater from entering within doors by the slit of extraction fan or fan and roofing.
