the name of the original invention is: a nostril lighting device for infants.
Technical Field
The invention discloses a first shielding plate and a nostril illuminating device with the same, and belongs to the fields of infant products, pediatric medical instruments, optical illumination and the like.
Background
The nasal discharge can obstruct breathing and bring uncomfortable feeling to people. Adult can pick out the nasal shit by himself when having the nasal shit in the nostril, however, for baby, because limbs are developed incompletely, can't dig the nasal shit voluntarily, therefore needs parental help.
However, since the baby does not understand the cooperation with parents, the baby can perform instinct resistance when digging the nasal discharge, the nasal mucosa is easily damaged, and the difficulty is brought to the development of the nasal discharge digging work.
Since the nasal discharge is hidden inside the nostril, the nostril of the infant needs to be illuminated, which puts high demands on the convergence properties of the illuminating light beams for the following reasons:
firstly, if the light beam is dispersed, the light beam can irradiate the eyes of the baby, so that the baby can wake from sound sleep, and the nose and feces digging work can not be carried out;
secondly, the nostrils of the baby are small, and if the light beam is diffused, the illumination intensity is possibly insufficient, and the difficulty in the operation of removing the nasal discharge is brought.
Therefore, the illuminating device with a good convergence function is a key auxiliary device for smoothly carrying out the nasal discharge digging work of the baby.
However, the light beams are divergent regardless of the daily lighting lamp and the flashlight, and the function of convergent lighting cannot be realized.
Disclosure of Invention
The invention provides a nostril illuminating device for infants, which can provide high-quality convergent illuminating light beams with a very simple structure aiming at meeting the requirement of illuminating nostrils in the operation of removing the nasal discharge of the infants.
The purpose of the invention is realized as follows:
the nostril illuminating device for the baby is characterized in that an objective lens, a pinhole, a first shielding plate, a second shielding plate and an ellipsoidal reflector are coaxially arranged in sequence in a shell along a light propagation direction; the focal position of the objective lens is superposed with the far focal position of the ellipsoidal reflector, and a pinhole is arranged at the superposed position; the parallel light beams irradiate the objective lens along the direction of the optical axis to form a point light source at the position of the pinhole, and the point light source is reflected to a near-focus position by an ellipsoidal reflector and converged into a point light spot; first shielding plate and the coaxial setting of second shielding plate, first shielding plate are the annular, and the second shielding plate is circular, and circle diameter is greater than the second shielding plate diameter in the first shielding plate, and first shielding plate and second shielding plate homoenergetic are followed the optical axis direction and are removed between pinhole and ellipsoidal reflector.
Above-mentioned nostril lighting device for baby, first shielding plate can remove along the optical axis direction between pinhole and ellipsoid speculum, realizes through following structure:
the side wall of the first shielding plate is provided with a plurality of openings and an extending end perpendicular to the optical axis, the inner wall of the shell is provided with a slide way and a first through groove, the openings are matched with the slide way, so that the first shielding plate can move along the optical axis direction, the extending end extends out of the first through groove, and the position of the first shielding plate in the shell is controlled by adjusting the position of the extending end;
the connection relation between the extension end and the first shielding plate is as follows: the extension end is connected with the first shielding plate through a rotating shaft, a spring is further installed between the extension end and the first shielding plate, and the extension end has a tendency of deviating from the first through groove under the action of the spring;
the side wall of the first through groove is in a sawtooth shape, the extending end can be clamped in each sawtooth, the extending end is positioned, and therefore the first shielding plate is positioned.
Above-mentioned nostril lighting device for baby, the second shielding plate can remove along the optical axis direction between pinhole and ellipsoid speculum, realizes through following structure:
the side wall of the second shielding plate is symmetrically provided with two supporting ends, the shell is symmetrically provided with two second through grooves, and the supporting ends extend out of the second through grooves; the outer shell is sleeved with threads, the annular rotating end moves back and forth through threaded rotation on the outer wall of the outer shell, a notch is formed in the end face of the annular rotating end, the inner surface of the notch is in interference fit with the outer ring of the bearing, an annular connecting end is installed on the inner ring of the bearing in interference fit, and the annular connecting end is connected with the supporting end.
Has the advantages that:
firstly, in the nostril illuminating device for the infant, the objective, the needle hole, the first shielding plate, the second shielding plate and the ellipsoidal reflector are coaxially arranged in the shell along the light propagation direction, so that the nostril illuminating device has the technical advantage of simple structure;
secondly, in the nostril illuminating device for the baby, because the first shielding plate and the second shielding plate are arranged, the annular illuminating light is provided, only irradiates the side wall of the nostril, but not irradiates the inside of the nostril, and compared with a circular illuminating light beam, the nostril illuminating device has the technical effect of illuminating the side wall of the nostril and also has the effect of protecting the nasal mucosa inside the nostril;
thirdly, in the nostril illuminating device for the baby, because the first shielding plate and the second shielding plate can move between the needle hole and the ellipsoidal reflector along the optical axis direction, the diameters, the illumination angles and the illumination intensity of the inner ring and the outer ring of the annular illumination light beam can be adjusted through the movement of the first shielding plate and the second shielding plate, so that the nostril illuminating device can be suitable for babies with different nose shapes and sizes, and the application range of the nostril illuminating device is enlarged;
fourthly, in the nostril illuminating device for the baby, as the ellipsoidal reflector is adopted for converging the light beams, compared with the traditional lens converging mode, the reflector can solve the aberration problem of the lens in principle, realize that no stray light irradiates the eyes of the baby, and effectively avoid the problem that the nasal shit digging work cannot be carried out because the baby is awake from a deep sleep due to the divergent light beams or the convergent light beams with aberration;
fifthly, in the nostril illuminating device for the infant, the bifocal conjugate property of the ellipsoidal reflector is fully utilized, namely, the property that light beams incident from a far focus can also be emitted from the far focus is utilized, and compared with a lens structure or a plane reflector or a spherical reflector, the nostril illuminating device has the beneficial effect of large-angle illumination, so that the illuminating light beams are cut off on the side wall of the nostril, and the nasal mucosa in the nostril is further protected.
