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 structure diagram of the infant nostril lighting device of this embodiment is as figure 1 Shown. In the infant nostril lighting device, an objective lens 1, a pinhole 2, a first shielding plate 3, a second shielding plate 4, and an ellipsoidal reflector 5 are coaxially arranged in a housing 6 along the light propagation direction; the focal point of the objective lens 1 The position coincides with the far focus position of the ellipsoidal reflector 5, and a pinhole 2 is set at the coincidence; the parallel beam illuminates the objective lens 1 along the optical axis, forming a point light source at the pinhole 2, and then is reflected by the ellipsoidal reflector 5 to the near focus position. Converges into a spot light spot; the first shielding plate 3 and the second shielding plate 4 are coaxially arranged, the first shielding plate 3 is annular, the second shielding plate 4 is circular, and the inner diameter of the first shielding plate 3 is larger than the second...

specific Embodiment 2

[0035] The infant nostril lighting device of this embodiment, on the basis of specific embodiment 1, further restricts that the first shielding plate 3 can move along the optical axis between the pinhole 2 and the ellipsoidal reflector 5, which is realized by the following structure:

[0036] The side wall of the first shielding plate 3 is provided with a plurality of notches 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. The notches and the slideway cooperate to make The first shielding plate 3 can move along the optical axis, and the protruding end 31 protrudes from the first through slot. By adjusting the position of the protruding end 31, the position of the first shielding plate 3 in the housing 6 is controlled;

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

specific Embodiment 3

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

[0042] The side walls of the second shielding plate 4 are symmetrically provided with two supporting ends 41, and the housing 6 is symmetrically provided with two second through grooves, and the supporting ends 41 extend from the second through grooves; There are threads. The ring-shaped rotating end 42 moves forward and backward by threading the outer wall of the housing 6. On the end surface of the ring-shaped rotating end 42, a notch is provided. The inner surface of the notch is installed in an interference fit with the outer ring of the bearing 43. In the inner ring, an annular connecting end 44 is installed with an interference fit, and the annular connecting end 44 is connected...

Abstract

The invention provides a second 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 nostrillighting device is arranged in a housing; an objective, a pinhole, a first baffle, the 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 arecoaxially 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 Infants". [0002] Original application date: 2017-01-11. [0003] Original application number: 2017100199593. [0004] Original invention name: Nostril lighting device for infants. Technical field [0005] The second shielding plate and the nostril lighting device with the second shielding plate of the present invention belong to the fields of baby products, pediatric medical equipment, optical lighting and the like. Background technique [0006] Booger obstructs breathing and causes uncomfortable feelings. When an adult has booger in his nostril, he can pull out the booger by himself. However, for infants, they cannot dig their booger on their own due to underdeveloped limbs, so parents’ help is needed. [0007] However, because babies do not know how to cooperate with their parents, they will instinctively resist when they pick their noses, which can easily cause dama...
