Abstract
The invention relates to a projector. The projector comprises a bulb, a housing, a wind shield, an air inlet, wherein the bulb possesses a first end and a second end which are opposite to each other in a vertical direction; the housing is provided with an opening at the position of the bulb; the wind shield is arranged in the opening and possesses two lateral margins which are opposite to each other, and the two lateral margins are slidingly arranged on the housing; the air inlet is arranged on the wind shield and is located between the two lateral margins, and the air inlet successively possesses a first opening width, a second opening width and the third opening width in the vertical direction. The first opening width and the third opening width are greater than the second opening width. When the first end of the bulb is higher than the second end, the position of the first opening width corresponds to the first end and the position of the second opening width corresponds to the second end. When the second end of the bulb is higher than the first end, the wind shield slides under an effect of gravity so that the position of the third opening width corresponds to the second end and the position of the second opening width corresponds to the first end. The projector can simultaneously satisfy different demands to airflow when the projector is placed and is inversely placed.
Description
Technical field
The present invention refers to a kind of projector that utilizes action of gravity adjustment air channel especially about a kind of projection arrangement.
Background technology
Please refer to Fig. 1, Fig. 1 is the structural representation of convention projector 10.Projector 10 can produce great amount of heat energy under in working order, mainly by 1 generation of bulb, so all indispensable lamp bulb cooling mechanism of projector 10, with the temperature of bulb 1 in the reduction work, avoid Yin Gaowen and damage and prolong serviceable life of bulb 1.As shown in Figure 1, the projector 10 of convention comprises the opening 4 on bulb 1, housing 2, abat-vent 3, the housing, and this opening 4 is provided with corresponding to bulb 1; These opening 4 places are provided with flange 21; This abat-vent 3 is provided with air inlet 33, first lateral margin, 31, the second lateral margins 32, and this abat-vent 3 is attached on this flange 21 through screw 22; Air communication is crossed air inlet 33 and is blowed to bulb 1, makes its cooling.Please refer to Fig. 2, Fig. 2 is air inlet in the convention projector 10 33 and bulb 1 relative position synoptic diagram.Bulb 1 has the first end A1 and the second end B1; Because the occurring in nature hot-air can upwards flow; When producing heat energy, heat energy can upwards be driven by hot-air when bulb 1 is luminous, makes that the first end A1 of the bulb 1 in the work is high compared to the temperature of the second end B1.In the situation of reality, the temperature spread of the first end A1 and the second end B1 even can surpass 200 degree or more than 300 degree.If air inlet 3 is sent to air-flow the temperature difference still excessive (more than the Baidu) of bulb 1, the first end A1 and the second end B1 equably, significantly influence the life-span of bulb 1.In addition, just put and be inverted two states because of the use of projector has, first end of bulb is different with the temperature distribution state of second end in the two states; When first end of bulb is higher than second end, promptly projection arrangement is when just putting state, and the temperature of first end is higher than the temperature of second end; When second end of bulb is higher than first end; Be projection arrangement when inversion state, the temperature of second end is higher than the temperature of first end, so; First end of bulb is different with the airflow requirement amount of second end in this two states, needs a kind of abat-vent of changeable different conditions.
Summary of the invention
The object of the present invention is to provide a kind of projection function steering current major part to blow to the higher end of temperature in the bulb; Reduce the temperature difference between bulb first end and second end; And can make projector all can realize reducing of upper and lower temperature difference, prolong the serviceable life of bulb in just being put on the table and hanging upside down in pushing up last time.
For achieving the above object, the present invention proposes a kind of projection arrangement, it is characterized in that comprising: bulb has the first relative end and second end on vertical direction; Housing is arranged at this bulb periphery, and is provided with opening corresponding to the position of this bulb; Abat-vent, vicinity is arranged at this opening part, and this abat-vent has the first relative lateral margin and second lateral margin, and this first lateral margin and this second lateral margin are mounted slidably on this housing; Be used to cool off the air inlet of this bulb; Be opened on this abat-vent and between this first lateral margin and this second lateral margin; This air inlet has first A/F, second A/F and the 3rd A/F successively on this vertical direction, this first A/F and the 3rd A/F are all greater than this second A/F; Wherein, When this first end of this bulb was higher than this second end, this first A/F place was corresponding to this first end, and this second A/F place is corresponding to this second end; When this second end of this bulb is higher than this first end; This abat-vent makes the 3rd A/F place corresponding to this second end in the action of gravity lower slider, and this second A/F place is corresponding to this first end.
As optional technical scheme, this of this bulb first end be higher than this second end corresponding to this projection arrangement in just putting state, this of this bulb second end be higher than this first end corresponding to this projection arrangement in inversion state.
As optional technical scheme, this of this abat-vent first lateral margin and this second lateral margin protrudes out and perpendicular to the plane of this air inlet, and this first lateral margin and this second lateral margin all have chute.
As optional technical scheme; This housing also comprises flange; Be arranged at the left and right sides of this opening; This chute place that this flange corresponds to this first lateral margin and this second lateral margin is provided with screw, and this screw is fixed in this flange and is arranged in this chute, and this chute is moved up and down in this screw place on this vertical direction.
As optional technical scheme; This air inlet has first air inlet separated from one another and second air inlet; This second air inlet be arranged at this first air inlet under; This first air inlet has the first long limit and first minor face on vertical direction, this second air inlet has second minor face and the second long limit on vertical direction.
As optional technical scheme, this projection arrangement is when just putting state, and this first air inlet is corresponding to this bulb, and this first long limit is corresponding to this first end of this bulb at this moment, and this first minor face is corresponding to this second end of this bulb; This projection arrangement is when the reversal of the natural order of things state, and this second air inlet is corresponding to this bulb, and this second long limit is corresponding to this second end of this bulb at this moment, and this second minor face is corresponding to this first end of this bulb.
As optional technical scheme, just putting when changing between state and the reversal of the natural order of things state in this when this projection arrangement, under action of gravity, this abat-vent slides on this vertical direction by this screw and this chute.
As optional technical scheme, this projection arrangement is provided with blasting unit, is connected in this abat-vent and in order to produce air-flow, this air communication is crossed this air inlet and blowed to this bulb.
The projection arrangement that the present invention disclosed can slide up and down abat-vent in a side setting of bulb; Changeable air inlet; Make no matter projection arrangement is just being put state or inversion state, the air inlet that is used all is higher ends of temperature in the corresponding bulb of longer sides, and than the lower end of temperature in the corresponding bulb of minor face; Blow to the higher end of bulb temperature with steering current most ofly; Thereby can reduce the temperature difference between bulb first end and second end, prolong the serviceable life of bulb, and can satisfy projection arrangement simultaneously and just putting and be inverted the different demands of two states air-flow.
