Technical field
First shutter of the invention and the nostril lighting device with the first shutter belong to articles for babies, paediatrics Medical treatment device
The fields such as tool and illumination optical.
Background technique
Nose dung can hinder to breathe, and bring uncomfortable feeling to people.It, can be certainly when adult has nose dung in nostril
Oneself plucks out nose dung, however, since limb development is not complete, can not independently dig nose dung, it is therefore desirable to the side of parent for baby
It helps.
But since baby does not understand cooperation parent, instinct resistance can be carried out when digging nose dung, is be easy to cause
Schneiderian membrane is damaged, brings difficulty to the development that nose dung works is dug, and solves the method for this problem exactly after baby sleep soundly, then give
Baby digs nose dung.
Since nose dung is ensconced inside nostril, it is therefore desirable to be illuminated to the nostril of baby, this convergence to illuminating bundle
Characteristic has very high requirement, the reason is as follows that:
If first, beam divergence, baby's eyes can be irradiated to, wake up baby from sleeping soundly, cause to dig the work of nose dung
Can not carry out；
The second, the nostril very little of baby, if beam divergence, it is inadequate to may cause illumination intensity, also can be to digging the work of nose dung
Development brings difficulty.
As it can be seen that a lighting device with good convergence function, is the key that smooth development baby digging nose dung work is auxiliary
Help equipment.
However, either normal lighting lamp, flashlight, light beam are all divergings, the effect for assembling illumination cannot achieve.
Summary of the invention
The demand illuminated in the work of nose dung to nostril is dug for baby is carried out, the present invention devises a kind of nostril photograph for baby
Bright device, the device can provide the convergence illuminating bundle of high quality with very simple structure.
The object of the present invention is achieved like this:
Nostril lighting device for baby is sequentially coaxially arranged object lens along the light direction of propagation, pin hole, first blocks inside the shell
Plate, the second shutter and ellipsoidal mirror；The objective focus positions and ellipsoidal mirror over focus position are overlapped, and are overlapped
Place's setting pin hole；Collimated light beam forms point light source along optical axis direction illumination objective, in pin hole position, using ellipsoidal mirror
Perifocus position is reflexed to, a hot spot is converged to；First shutter and the coaxial arrangement of the second shutter, the first shutter are
Annular, the second shutter are circle, and circular diameter blocks board diameter greater than second in the first shutter, and the first shutter and second hide
Baffle can move between pin hole and ellipsoidal mirror along optical axis direction.
Above-mentioned nostril lighting device for baby, first shutter can be between pin hole and ellipsoidal mirrors along light
Axis direction is mobile, by being realized with flowering structure:
The side wall of first shutter is provided with the extension end of multiple gap and a vertical optical axis, and the inner wall of shell is provided with
Slideway and the first through slot, the gap and slideway match, and the first shutter is enable to move along optical axis direction, the extension end
It is stretched out from the first through slot, by adjusting the position of extension end, controls the position of the first shutter in the shell；
Connection relationship between the extension end and the first shutter are as follows: extension end is connect by shaft with the first shutter,
Between extension end and the first shutter, it is also equipped with spring, under the action of the spring, extension end, which has, deviates becoming for the first through slot
Gesture；
The first through slot side wall is zigzag, and extension end can be stuck in each sawtooth, realizes the positioning to extension end, in turn
Realize the positioning to the first shutter.
Above-mentioned nostril lighting device for baby, second shutter can be between pin hole and ellipsoidal mirrors along light
Axis direction is mobile, by being realized with flowering structure:
There are two support ends for the sidewall symmetry setting of second shutter, and shell is arranged symmetrically, and there are two the second through slots, described
Support end is stretched out from the second through slot；It is cased with screw thread on the shell, ring rotation end is realized by rotating in shell outer wall thread
It is moved forward and backward, on the end face at ring rotation end, is provided with recess, the recess inner surface and bearing outer ring interference fit are pacified
Dress, in bearing inner race, interference fit installs annular connecting pin, and the annular connecting pin connects support end.
The utility model has the advantages that
The first, in present invention nostril lighting device for baby, due to inside the shell, only including successively same along the light direction of propagation
Object lens, pin hole, the first shutter, the second shutter and ellipsoidal mirror is arranged in axis, and number of elements is few, therefore has structure letter
Single technical advantage；
The second, it in present invention nostril lighting device for baby, due to being provided with the first shutter and the second shutter, mentions
What is supplied is ring illumination light, only irradiates nostril side wall, without irradiating inside nostril, compared with circular illumination light beam, in addition to same
Outside with the technical effect illuminated to nostril side wall, also have the function of protecting schneiderian membrane inside nostril；
Third, in present invention nostril lighting device for baby, since the first shutter and the second shutter can be in pin holes
It moves, therefore can be adjusted by the movement of the first shutter and the second shutter along optical axis direction between ellipsoidal mirror
The inside and outside loop diameter of domain shape illuminating bundle, irradiating angle, exposure intensity can be suitable for different nose shapes, size
Baby, increase the scope of application of nostril lighting device；
4th, in present invention nostril lighting device for baby, due to carrying out light beam convergence using ellipsoidal mirror, with tradition
Lens are assembled mode and are compared, and reflecting mirror can solve the Aberration Problem of lens from principle, realize and irradiate baby eyes without stray light
Eyeball effectively avoids divergent beams or has aberration convergent beam to wake up baby from sleeping soundly, and causes digging nose dung work can not
Progress the problem of；
5th, in present invention nostril lighting device for baby, make full use of ellipsoidal mirror bifocus conjugated nature, i.e., it is sharp
The property that can also be emitted from over focus with the light beam from over focus incidence, with lens arrangement or plane mirror or spherical reflector
It compares, the beneficial effect with large angle illumination, so that illuminating bundle ends in nostril side wall, further protects inside nostril
Schneiderian membrane.
