Description

Multifunctional strong exhaust fan

The utility model---multifunctional powerful ventilation fan is to belong to ventilation equipment technical fields such as vehicle, boats and ships.It generally is used for being contained in envelope ceilings such as car, ship, links up in the railway carriage or compartment and atmosphere outside.It both can utilize blowing or the air draft outside the compartment automatically in the compartment of the travelling speed of car and boat own, and the electric fan blowing or the outwards air draft in the compartment by force that can utilize this device to be provided with again used when this is more suitable for vehicle lay-off.Certainly in when driving if start electric fan simultaneously, then more can strengthen the power of this device.

Passenger vehicle (or passenger boat) is the public place in the compartment, and air is contaminated easily, must take a breath in good time.Prior art generally puts in a skylight at car body top, takes a breath by opening the skylight.Develop the motorcar electric ventilation fan in recent years abroad, domesticly in this kind of import equipment, also copy, be used to be equipped with domestic motor bus.Because this electric fan price is too high, air quantity is too little again, and except that the air-conditioning motor bus must be adorned usefulness, common motor bus and minibus etc. were difficult for accepting extensively.Work out the utility model in person in order to replace above-mentioned air interchanger for this reason.

The utility model has adopted inverted dustpan shape outer cover, an opening, and having keeps watch gathers the effect that is pressed in the railway carriage or compartment, and this just can make wind-force strengthen greatly, and prior art electric fan outer cover does not have the effect of gathering to wind, so wind-force is too little.The utility model general configuration as shown in drawings.Wherein the parts general configuration is as follows in addition:

1---closing cap: be that garden shape steel plate is made, some limits of all edge breaks to increase the intensity of in-plane, keep moulding rigidity.

2---seal ring: be the about 5 millimeters rubber product of thickness, be pasted on the inner surface edge of other part (1).Has elasticity.

3---the air channel: be that thick about 1 millimeter steel plate encloses volume and is welded, the several millimeter of top periphery outward flanging, the intensity of increase own increases the area of contact with other part (2) on the other hand on the one hand.

4---screw: adopt Stainless Steel Products, other part (10) is fixed on other part (16);

5---filler strip: be that a kind of cross section is the rubber or the soft goods of moulding of hollow garden tubulose, (being commonly called as " 9 " font rubber bar) has elasticity, and it can regulate the tightness degree that contacts of other part (10) and compartment ceiling.

6---miniature deceleration lift structure: though its volume is little, about 60 * 50 * 40 millimeters dimension, but it is easily controlled, and can export very big moment, even can lift several kilograms of weights, by being connected in the spring bearer plate on other part (1), other position of part (1) is controlled, other was raise by part (1), be closely attached on the internal surface of other part (10), can be pressed in again on the actinal surface of other part (3).The control of its action very easily realizes by switching circuit.

7---fan guard: be connected in other part (3) bottom, be close to the compartment internal surface, play protection fans and attractive, decorative effect.

8---fans: be the duroplasts goods, diameter is between the 200-450 millimeter.

9---pad: be the wool felt goods, thick several approximately millimeter is pasted on the upper surface of other part (1), plays and cushions and the effect of reducing friction.

10---outer cover: be thick about 1 millimeter steel plate goods, also can be with making such as plastic shaping or glass fibre reinforced plastics.It roughly resembles a shape of falling the dustpan, and an end that seals certainly is a garden arc interim form, and is more attractive in appearance on the one hand, conforms with fluid mechanics principle in addition.

11---fan electromotor: its radial length is suitable littler, can not be subjected to the restriction of ceiling thickness, and its verticity should be able to rotate and reverse, and reaches the purpose of air intake or air draft.

12---weather shield: be lamellar article, its cross section is anchored on other part (10) from the horizontal by 20-60 degree angle, and it can stop that outside rainwater invades other part (3), does not influence air intake again.

13---outer cover mouth net: be metal or plastic web, retaining stops that at the opening end of other part (10) leaf, waste paper fly into other part (10) inside.

14---outer cover mouth circle: be fixed in the opening end of other part (10), rise and reinforce other part (10) and decorating action.It can be the steel plate goods, also can with the compound duroplasts goods of making of other part (13).

15---damping washer: sticking on other part (16) and other part (3) on every side, is a kind of rubber product, and the cross section is a rectangle.When with screw with other part (16) when being fixed on roof, part (15) is compacted in addition, plays damping and seal action.

16---the rib circle: it makes the body of circular fold shape with thick about 2 millimeters steel plate, be welded on the waistline place of other part (3), play a part on the one hand to strengthen, support other part (3), on the other hand by the screw effect, it is fastened onto the bicycle shed top, and part (10) is also fixed by it in addition.

17---car body ceiling interlayer: its thickness determines the height of other part (3).

The principle of work and power of the present utility model is roughly as follows:

As shown in drawings, if vehicle travels to right-hand, the wind-force that is formed by the speed of a motor vehicle blows in other part (10).When other part (1) was in position in the accompanying drawing (depressing), wind can't enter in other part (3), and this moment, the compartment was sealed by this device.After starting electrical switch, then parts (6) drive other part (1) and upwards are close to other part (10) internal surface, and part (3) actinal surface is opened in addition, and then wind directly blows in the compartment after can gathering by other part (3) inside, the formation large wind.This moment, then wind-force more strengthened if start other part (11) simultaneously.

General bigger vehicle needs two above the utility model of device.With two is example, should make headstock part one entablature towards preceding during assembling, behind the car entablature towards after, during vehicle driving, open the in addition part (1) of two table apparatus, one of front is with regard to air intake, and one of back is because of fluid negative-pressure effect air draft, form the wind-force distribution channel, rapidly the car body top vitiated air is discharged.Therefore, the per car device is this device more than two, more can give full play to air intake, air draft effectiveness.

The utility model manufacturing process is simpler than prior art motorcar electric ventilation fan, but because it has the inaccessiable ventilation power of the latter, so it has bigger use value, from its structure, also have novelty and aesthetic property, very practical concerning the way-train of higher class.
