Rotary inductive module 168 comprises control circuit 1682 and is fixed on the optical sensor 1684 on control circuit 1682, and optical sensor 1684 has sensitive surface 1684a.Rotary inductive module 168 is fixed on fixed mount 1644, makes sensitive surface 1684a towards surface of revolution 1622a, and then can respond to the rotation of surface of revolution 1622a.In the present embodiment, fixed mount 1644 has a through hole 1644a, control circuit 1682 (such as but not limited to circuit board module) is upwards fixed on fixed mount 1644 from the below of Fig. 4, optical sensor 1684 is made to be fixed on fixed mount 1644 by control circuit 1682 and to be placed in through hole 1644a, sensitive surface 1684a exposes via through hole 1644a with facing to surface of revolution 1622a, makes the rotation of optical sensor 1684 energy sensing rotation surface 1622a (or tumbler 1622) via sensitive surface 1684a.Referring to the front elevation that Fig. 6, Fig. 6 are colour wheel module 16; Wherein, fixed mount 1644 illustrates in the mode of part section.Arc-shaped curved surface 16462 and sensitive surface 1684a are according to sense of rotation 1622b (being shown in Fig. 6 with arrow) sequential.With the visual angle of Fig. 6, the space between dustproof construction 1646 and surface of revolution 1622a is aforementioned narrow passage.The air-flow caused because surface of revolution 1622a rotates is subject to the restriction of this slype, and only a fraction of air-flow is able to by this slype and can arrives sensitive surface 1684a, and the amount of dust be therefore deposited on sensitive surface 1684a can be effectively suppressed.What remark additionally is, in the present embodiment, sensitive surface 1684a is lower than the extension line (as shown in phantom in Figure 6) of arc-shaped curved surface 16462, this arranges to help avoid and directly impacts sensitive surface 1684a by the air-flow of this slype, also contributes to the amount of dust suppressing to be deposited on sensitive surface 1684a.
Be that colour wheel module 16 is in the schematic diagram at another visual angle referring to Fig. 7, Fig. 7; Wherein, whirligig 162 and colour wheel 166 are not all illustrated in figure.Furthermore, in the present embodiment, the groove bottom of guide groove 16464 and the spacing of surface of revolution 1622a are greater than the spacing of arc-shaped curved surface 16462 and surface of revolution 1622a, the resistance to flow of air-flow between guide groove 16464 and surface of revolution 1622a is less, after making air-flow enter the slype formed between surface of revolution 1622a and arc-shaped curved surface 16462 and guide groove 16464, tendency enters between guide groove 16464 and surface of revolution 1622a and flows.Again, the extension path of guide groove 16464 extension line (as in Fig. 7 with shown in the thick dashed line of arrow) the sensitive surface 1684a of logical optical sensor 1684.Therefore, with sense of rotation 1622b or show greatly the air-flow that sense of rotation 1622b (being shown in Fig. 7 with thick-line arrow) flows can not flow through sensitive surface 1684a in principle after departing from slype between guide groove 16464 and surface of revolution 1622a, the dust be suspended in the air-flow of this part can not be deposited on sensitive surface 1684a; In other words, by guide groove 16464 to the guide function of air-flow entering slype (being formed between surface of revolution 1622a and arc-shaped curved surface 16462 and guide groove 16464), the air-flow entering slype not all can flow through sensitive surface 1684a, therefore can suppress the dust deposit amount on sensitive surface 1684a further.By the setting of guide groove 16464, solve stop block structure in prior art and cannot suppress the problem of dust deposit to the air-flow entered between stop block structure and motor shaft further.
In the present embodiment, arc-shaped curved surface 16462 sequentially has the first section 16462a and the second section 16462b (in Fig. 7 according to sense of rotation 1622b, all with its scope of empty wire frame representation), the first distance 16463a is formed between the first section 16462a and surface of revolution 1622a, form second distance 16463b between the second section 16462b and surface of revolution 1622a, the first distance 16463a is greater than second distance 16463b.In practical operation, arc-shaped curved surface 16462 is parallel or be roughly parallel to surface of revolution 1622a and arrange, and the distance between arc-shaped curved surface 16462 and surface of revolution 1622a can be asymptotic change, produces to reduce flow-disturbing.Now aforementioned first distance 16463a can be considered the distance average between the first section 16462a and surface of revolution 1622a, and aforementioned second distance 16463b can be considered the distance average between the second section 16462b and surface of revolution 1622a; But the present invention is not as limit.Only to consider arc-shaped curved surface 16462, because the first distance 16463a is greater than second distance 16463b, the air-flow flowed between arc-shaped curved surface 16462 and surface of revolution 1622a produces than resistance larger when flowing through the first section 16462a in time flowing through the second section 16462b, and this orders about tendency when air-flow flow to the second section 16462b and flows out from the second section 16462b both sides; In other words, only wherein the air-flow of a part can flow out this slype (being formed between arc-shaped curved surface 16462 and surface of revolution 1622a) from the second section 16462b with sense of rotation 1622b, and then can reach sensitive surface 1684a.Therefore, changed by the distance convergent between arc-shaped curved surface 16462 and surface of revolution 1622a, the air-flow entering this slype not all can flow through sensitive surface 1684a, therefore can suppress the dust deposit amount on sensitive surface 1684a further.Therefore, change by the distance convergent between arc-shaped curved surface 16462 and surface of revolution 1622a, also can solve stop block structure in prior art and cannot suppress the problem of dust deposit to the air-flow entered between stop block structure and motor shaft further.
In the present embodiment, dustproof construction 1646 has the architectural feature that the setting of guide groove 16464 and the distance convergent between arc-shaped curved surface 16462 and surface of revolution 1622a change concurrently, dustproof construction 1646 provides the effect that in double inhibition air-flow, dust deposits in sensitive surface 1684a, but the present invention is not as limit.In practical operation, on dustproof construction, select an architectural feature (arranging guide groove or arc-shaped curved surface and surface of revolution spacing to change) arrange, can realize to the air-flow entered between dustproof construction and surface of revolution the deposition suppressing dust in sensitive surface further.In addition, in practical operation, the length that the slype formed when between surface of revolution 1622a and arc-shaped curved surface 16462 and guide groove 16464 extends in sense of rotation 1622b is longer, more contributes to the aforementioned performance (that is reduce directly flow to the air-flow of sensitive surface 1684a) of guide function to entering air-flow in slype.In the present embodiment, arc-shaped curved surface 16462 extends at least 45 degree along sense of rotation 1622b, or arc-shaped curved surface 16462 hides the surface of revolution 1622a anglec of rotation more than 45 degree along sense of rotation 1622b; But the present invention is not as limit.In addition, in the present embodiment, all adjacent arc-shaped curved surface 16462 of whole guide groove 16464 arranges and communicates, but the present invention is not as limit.As shown in Figure 8, in another embodiment, the guide groove 16474 of dustproof construction 1647 the adjacent arc-shaped curved surface 16462 of non-integral homogeneous phase are arranged, a guide groove 16474 only part is disposed adjacent with the first section 16462a and communicates, other parts of guide groove 16474 then can depart from sense of rotation 1622b and extend, even depart from surface of revolution 1622a, namely no longer just to surface of revolution 1622a, this structural allocation contributes to departing from the air-flow of dustproof construction 1647 further from sensitive surface 1684a via guide groove 16474, that is more reduce the impact (such as this air-flow in dust deposit in sensitive surface 1684a on) of this air-flow on sensitive surface 1684a.
