Nostril Lighting Device for Babies

Abstract

The invention discloses a nostril illumination device for a baby, and belongs to the fields of baby products, pediatric medical equipment, optical illumination and the like. An object lens, a pinhole, a first baffle plate, a second baffle plate and an elliptical reflector are coaxially arranged in sequence in a housing of the illumination device along a light propagation direction, wherein the focus position of the object lens is overlapped with the far focus position of the elliptical reflector, and the pinhole is formed in the overlapping part; parallel beams irradiate the object lens along the direction of the optical axis, form a point light source at the position of the pinhole, and are reflected to the close focus position through the elliptical reflector, and are converged into a point light spot; the first and second baffle plates are coaxially arranged, the first baffle plate is annular, the second baffle plate is circular, the diameter of the inner circle of the first baffle plate is larger than the diameter of the second baffle plate, and both the first and second baffle plates can move along the direction of the optical axis between the pinhole and the elliptical reflector. According to the nostril illumination device for the baby, a high-quality convergent illumination beam can be provided with a very simple structure.

Description

technical field [0001] The nostril illuminating device for babies of the present invention belongs to the fields of baby products, pediatric medical equipment, optical lighting and the like. Background technique [0002] 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. [0003] However, because the baby does not know how to cooperate with the parents, it will instinctively resist when digging the nose, which may easily cause damage to the nasal mucosa and bring difficulties to the work of picking the nose. Booger picking for babies. [0004] Because boogers are hidden inside the nostrils, it is necessary to illuminate the baby's nostrils, which has high requirements on the converging characteristics of the lighting beam, for the following re...

AI Technical Summary

Problems solved by technology

[0005] 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;

[0006] 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.

[0008] 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.
