Problems solved by technology

[0009] First, if the light beam diverges, it will irradiate the baby's eyes, causing the baby to wake up from a deep sleep, making it impossible to pick boogers;
[0010] Second, the baby's nostrils are very small. If the light beam diverges, the lighting intensity may not be enough, and it will also bring difficulties to the nose picking work.
[0012] However, whether it is a daily lighting lamp or a flashlight, the light beams are divergent, and the function of convergent lighting cannot be achieved.

specific Embodiment 1

[0034] The infant nostril illuminating device of this embodiment, the structural schematic diagram is as follows figure 1 shown. The baby's nostril illuminating device, in the housing 6, is coaxially arranged with the objective lens 1, the pinhole 2, the first shading plate 3, the second shading plate 4 and the ellipsoid reflector 5 successively along the light propagation direction; The position coincides with the position of the far focus of the ellipsoidal reflector 5, and a pinhole 2 is arranged at the coincident place; the parallel light beam irradiates the objective lens 1 along the optical axis, and a point light source is formed at the position of the pinhole 2, and then reflected to the near focus position by the ellipsoidal reflector 5, Converge into a point spot; the first baffle plate 3 and the second baffle plate 4 are coaxially arranged, the first baffle plate 3 is ring-shaped, the second baffle plate 4 is circular, and the diameter of the inner circle of the fir...

specific Embodiment 2

[0035] The nostril illuminating device for infants in this embodiment, on the basis of the first embodiment, further defines that the first shielding plate 3 can move along the optical axis between the pinhole 2 and the ellipsoidal reflector 5, and is realized by the following structure:

[0036] The side wall of the first shielding plate 3 is provided with a plurality of gaps and a protruding end 31 perpendicular to the optical axis, and the inner wall of the housing 6 is provided with a slideway and a first through groove, and the gaps and the slideway are matched so that The first shielding plate 3 can move along the direction of the optical axis, the protruding end 31 protrudes from the first through groove, and the position of the first shielding plate 3 in the housing 6 is controlled by adjusting the position of the protruding end 31;

[0037] The connection relationship between the extending end 31 and the first shielding plate 3 is: the extending end 31 is connected wit...

specific Embodiment 3

[0041] The nostril illuminating device for infants in this embodiment, on the basis of the specific embodiment 1, further defines that the second shielding plate 4 can move along the optical axis between the pinhole 2 and the ellipsoidal reflector 5, and is realized by the following structure:

[0042] The side wall of the second shielding plate 4 is symmetrically provided with two supporting ends 41, and the casing 6 is symmetrically provided with two second through grooves, and the supporting ends 41 protrude from the second through grooves; There are threads, and the annular rotating end 42 moves back and forth by threading on the outer wall of the housing 6. On the end face of the annular rotating end 42, a notch is provided, and the inner surface of the notch is installed with an interference fit with the outer ring of the bearing 43. The inner ring is fitted with an annular connection end 44 with an interference fit, and the annular connection end 44 is connected to the s...

Abstract

The invention provides a first baffle and a nostril lighting device with the same and belongs to the fields, such as infant products, pediatric medical instruments, and optical lighting. The nostril lighting device is arranged in a housing; an objective, a pinhole, the first baffle, a second baffle and an ellipsoidal reflector are arranged coaxially and sequentially along a light propagation direction; a focus of the objective and a far focus of the ellipsoidal reflector are positionally overlaid, and the pinhole is arranged in the overlay; parallel beams irradiate the objective along the optical axis, forming a point source at the pinhole; the point source is reflected by the ellipsoidal reflector to a close focus, condensing into a light spot; the first baffle and the second baffle are coaxially arranged; the first baffle is in ring shape; the second baffle is circular; the inner circle diameter of the first baffle is greater than the diameter of the second baffle; both the first baffle and the second baffle can move along the optical axis between the pinhole and the ellipsoidal reflector. The nostril lighting device for babies can provide high-quality condensed lighting beams with very simple structure.

Description

[0001] This application is a divisional application of the invention patent application "Nostril Lighting Device for Babies". [0002] The original filing date: 2017-01-11. [0003] Original application number: 2017100199593. [0004] Title of the original invention: Nostril lighting device for infants. technical field [0005] The first shading plate and the nostril lighting device with the first shading plate of the present invention belong to the fields of baby products, pediatric medical equipment, optical lighting and the like. Background technique [0006] Boogers obstruct breathing and can be uncomfortable. When adults have boogers in their nostrils, they can pick out the boogers by themselves. However, for babies, due to their underdeveloped limbs, they cannot dig out the boogers independently, so they need the help of their parents. [0007] However, because the baby does not know how to cooperate with the parents, it will instinctively resist when digging the no...
