技术领域technical field
本发明第二遮挡板和具有第二遮挡板的鼻孔照明装置属于婴儿用品、儿科医疗器械和光学照明等领域。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 instruments, optical lighting and the like.
背景技术Background technique
鼻屎会阻碍呼吸,给人带来不舒服的感觉。成年人在鼻孔中有鼻屎的时候,能够自己将鼻屎抠出,然而,对于婴儿,由于肢体发育不全,无法自主挖鼻屎,因此需要家长的帮助。Booger can obstruct breathing and cause discomfort. When adults have boogers in their nostrils, they can pull out the boogers by themselves. However, for infants, due to underdeveloped limbs, they cannot dig the boogers on their own, so they need the help of parents.
但是,由于婴儿不懂得配合家长,因此会在挖鼻屎的时候进行本能反抗,容易造成鼻粘膜破损,给挖鼻屎工作的开展带来困难,解决这个问题的方法就是在婴儿熟睡后,再给婴儿挖鼻屎。However, because babies do not know how to cooperate with their parents, they will instinctively resist when picking boogers, which will easily cause damage to the nasal mucosa and bring difficulties to the development of booger picking. Pick up baby's booger.
由于鼻屎藏在鼻孔内部,因此需要对婴儿的鼻孔进行照明,这对照明光束的会聚特性有着很高的要求,原因如下:Since the boogers are hidden inside the nostrils, the baby's nostrils need to be illuminated, which has high requirements on the converging characteristics of the illumination beam for the following reasons:
第一、如果光束发散,会照射到婴儿眼睛,使婴儿从熟睡中清醒过来,造成挖鼻屎工作无法进行;First, if the light beam diverges, it will irradiate the baby's eyes, so that the baby wakes up from a deep sleep, making it impossible to pick the nose;
第二、婴儿的鼻孔很小,如果光束发散,可能造成照明强度不够,也会给挖鼻屎工作的开展带来困难。Second, the baby's nostrils are very small. If the beam is divergent, it may cause insufficient lighting intensity, which will also bring difficulties to the development of booger picking.
可见,一个具有良好会聚功能的照明装置,是顺利开展婴儿挖鼻屎工作的关键辅助设备。It can be seen that a lighting device with a good convergence function is a key auxiliary device for the smooth development of the baby's nose picking work.
然而,无论是日常照明灯、手电,光束都是发散的,无法实现会聚照明的作用。However, whether it is a daily lighting lamp or a flashlight, the light beam is divergent and cannot achieve the effect of convergent lighting.

有益效果:Beneficial effects:
第一、在本发明婴儿用鼻孔照明装置中,由于在外壳内,仅包含沿光线传播方向依次同轴设置物镜、针孔、第一遮挡板、第二遮挡板和椭球面反射镜,元件数量少,因此具有结构简单的技术优势;First, in the baby nostril lighting device of the present invention, because in the housing, only the objective lens, the pinhole, the first shielding plate, the second shielding plate and the ellipsoid reflector are arranged coaxially along the light propagation direction in sequence, and the number of components. Therefore, it has the technical advantage of simple structure;
第二、在本发明婴儿用鼻孔照明装置中,由于设置有第一遮挡板和第二遮挡板,因此提供的是环形照明光,只照射鼻孔侧壁,而不照射鼻孔内部,同圆形照明光束相比,除了同样具有给鼻孔侧壁照明的技术效果外,还具有保护鼻孔内部鼻粘膜的作用;Second, in the infant nostril lighting device of the present invention, since the first shielding plate and the second shielding plate are provided, the annular illumination light is provided, which only illuminates the side walls of the nostrils and does not illuminate the interior of the nostrils, which is the same as the circular illumination. Compared with the light beam, in addition to the technical effect of illuminating the side walls of the nostrils, it also has the effect of protecting the nasal mucosa inside the nostrils;
第三、在本发明婴儿用鼻孔照明装置中,由于第一遮挡板和第二遮挡板均能够在针孔和椭球面反射镜之间沿光轴方向移动,因此能够通过第一遮挡板和第二遮挡板的移动,调整环形照明光束的内外圈直径,照射角度,照射强度,使其能够适用于不同鼻子形状、大小的婴儿,增加了鼻孔照明装置的适用范围;Third, in the baby nostril lighting device of the present invention, since both the first shielding plate and the second shielding plate can move in the direction of the optical axis between the pinhole and the ellipsoid reflector, they can pass through the first shielding plate and the second shielding plate.
