Abstract

The utility model relates to a lighting earpick which is provided with a transparent light guide rod (1) at the front end; the tail end of the light guide rod (1) is fixed with a microscler hand grip (9) to form a whole, and the front end of the light guide rod is a circular arc shaped earpick; the lighting earpick is characterized in that: the hand grip (9) is a hollow box body, a high brightness photod (2) facing to the light guide rod (1) and a photoresistance (6) embedded inside a shell of the hand grip (9) are arranged at the joint of the hand grip and the light guide rod (1); a photosurface of the photoresistance (6) is arranged towards the outer side, and the shell is provided with holes; the outer surface in the middle part of the hand grip (9) is fixed with a metal touch button (3), and the tail of the hand grip is provided with a cell box of a built-in button cell (5). When the touch button (3) of the earpick is pinched by hand and the front end of the earpick stretches into the meatus acusticus, the light guide rod (1) at the front end automatically lights, and the light guide rod automatically extinguishes when being taken out, so that the lighting earpick has the advantages of convenient use, small volume without other auxiliary equipment and automatic power saving.

Description

The illumination earpick

Technical field

This utility model relates to articles for daily use, is the illumination earpick that a kind of front end energy is luminous and can economize on electricity automatically specifically.

Background technology

Common earpick is simple in structure, oneself use also very convenient, but when needing others to help, because the auditory meatus the inside is black, how the doctor cooperates bulb aiming auditory meatus inside to operate with wearing condenser lens, and it is many to relate to equipment, also inconvenient, and individual's use can not be equipped with these equipment usually.

Summary of the invention

The purpose of this utility model provide a kind of convenience small and exquisite can be after entering auditory meatus, front end is luminous illumination earpick automatically.

Described illumination earpick, its front end is transparent leaded light bar 1, leaded light bar 1 tail end and microscler handle 9 are fixed as one, front end is the circular arc earpick, it is characterized in that: handle 9 is a hollow box, the junction of itself and leaded light bar 1 is provided with a high-luminance light electric diode 2 in the face of leaded light bar 1, with a photoconductive resistance 6 that embeds in handle 9 shells, photoconductive resistance 6 photosurfaces toward the outer side, this place's shell has the hole, handle 9 middle part outer surfaces are fixed a nugget genus touch button 3, and afterbody is provided with the battery case of a built-in button cell 5.

A printed circuit board 7 is equipped with in handle 9 inside of described illumination earpick, be welded with light-operated touch circuit 10 on the printed circuit board (PCB) 7, button cell 5 just, negative pole respectively with light-operated touch circuit 10 just, the negative supply input links to each other, the negative electrode of photodiode 2 links to each other with the outfan of light-operated touch circuit 10, anode is connected by the positive pole of current-limiting resistance with button cell 5, touch button 3 is connected with the touch signal input 11 of light-operated touch circuit 10, and the two ends of photoconductive resistance 6 are connected with the photoconductive resistance input 12 of light-operated touch circuit 10 and the negative pole of button cell 5 respectively.

This utility model just can make photodiode luminous by two conditions of touch of lower illuminance and hands are satisfied simultaneously, and direct light into the front end earpick by the leaded light bar, illuminate auditory meatus inside by the leaded light bar simultaneously, no longer need other equipment, photodiode extinguished automatically when the illumination earpick took out, to play the effect of economize on electricity, need only hands when the individual uses and do not touch touch button, can not make photodiode luminous yet, owing to used the very high COMS integrated circuit CD4011 of input resistance, the noise signal of experiencing human body that can be quick, make circuit itself can discern the touch of human body, simultaneously cmos circuit and the power consumption of highlighted photodiode own are extremely low, by photoconductive resistance with the lighting change luminance, reach power saving and the luminous effect of control automatically.

Therefore, the utlity model has easy to usely, volume is small and exquisite, does not need miscellaneous equipment auxiliary, automatically the advantage of economize on electricity.

Description of drawings

Fig. 1 is this utility model structural representation,

Fig. 2 is the left view of Fig. 1,

Fig. 3 is circuit theory diagrams of the present utility model.

Among the figure: 1-leaded light bar, 2-photodiode, 3-touch button, 4-battery case, the 5-button cell, 6-photoconductive resistance, 7-printed circuit board (PCB), 8-CD4011 four NAND gate circuits, the 9-handle, the light-operated touch circuit of 10-, 11-touch signal input, 12-photoconductive resistance input.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further specified: as Fig. 1, it shown in 2 the structure of this utility model appearance, its front end has a leaded light bar 1 made from transparent material, the front end of leaded light bar 1 is made the shape of earpick, there is the photodiode 2 of a light-emitting area towards leaded light bar 1 rear end of leaded light bar 1, near the photodiode 2 aperture is arranged simultaneously, a photoconductive resistance 6 is housed in the hole, the middle part of handle 9 is embedded with a metal touch button 3, afterbody is a battery case 4, correctly pack in the battery case 4 behind the button cell 5, the illumination earpick just can have been worked, when forward photoconductive resistance 6 places illumination deficiency, when hands was touched touch button 3 simultaneously, photodiode 2 just can be luminous, and light will illuminate on every side by the leaded light bar 1 of front end.

Printed circuit board (PCB) 7 is installed in handle 9 inside, its circuit theory diagrams as shown in Figure 3, using cheap CMOS integrated circuit CD4011 four NAND gate circuits 8 is the core of light-operated touch circuit 10, a printed circuit board 7 is equipped with in handle 9 inside of illumination earpick, be welded with light-operated touch circuit 10 on the printed circuit board (PCB) 7, button cell 5 just, negative pole respectively with light-operated touch circuit 10 just, the negative supply input links to each other, the negative electrode of photodiode 2 links to each other with the outfan of light-operated touch circuit 10, anode is connected by the positive pole of current-limiting resistance with button cell 5, touch button 3 is connected with the touch signal input 11 of light-operated touch circuit 10, and the two ends of photoconductive resistance 6 are connected with the photoconductive resistance input 12 of light-operated touch circuit 10 and the negative pole of button cell 5 respectively.

Need not external light source during use, operator's hands pinches metal touch button 3, and the earpick front end is stretched in ear, and its front end leaded light bar 1 promptly can send light, can conveniently operate, and its photodiode extinguished automatically when earpick was taken out.When oneself uses, as long as hands does not touch touch button 3, can be used as common earpick and use, its photodiode 2 can be not luminous.Because overall power is extremely low, time spent power consumption is not minimum at ordinary times.
