Abstract
The utility model discloses a noise-proof earplug which mainly comprises a casing (1), an umbrella crown (2), a gas guide hole (3) and a damping material (4). The shape of the casing is tally with the human ear canal and external ear, the casing is filled with damping material, and the inner end is provided with the umbrella crown. The existing earplugs in markets have the disadvantages that after long-time wearing, the ear feels swell, causing the feeling of dizziness and nausea, and the existing earplugs can be easily dropped off and lost. The utility model skillfully makes use of the physiologic tendency of the human ear, so the utility model overcomes the existing disadvantages of earplugs and earmuffs. The utility model has the advantage of convenient carryover. The utility model can be an ideal tool for preventing noise.
Description
This utility model belongs to its anti-noise field of tool, and what relate generally to is a kind of novel ear plug.
At present, its anti-noise instrument of selling on the market mainly contains earmuff and noise reduction earplug.Earmuff and noise reduction earplug are in the effect that truly has aspect the protection audition, but in use there are many weak points in it: earmuff needs whole auricle is encased, and in the workshop of temperature height, high humidity, wears very uncomfortable for a long time, and, carry extremely inconvenient because its volume is big; Though noise reduction earplug volume is little, it is to utilize earplug filled in to play sound insulation and fixation in the external auditory meatus, and Ruo Saidetai is tight, after the long periods of wear, in ear is swollen, and causes people's dizziness, dim eyesight, and with nauseating symptom, Ruo Saide is not tight, does not then have noiseproof effect, and easily comes off, loses.
In view of the deficiency that above-mentioned its anti-noise instrument exists, the purpose of this utility model is to provide a kind of comfortable wearing, volume is little, soundproof effect good, and novel ear plug without any side effects.
For achieving the above object, this utility model is achieved through the following technical solutions: it is made up of shell, umbrella crown, gas port and filling damping material in the enclosure, the shape of shell matches with ears screen, ears wheel, tragus, the external auditory meatus of human body from outside to inside successively, inner end at shell is provided with umbrella crown, and umbrella crown and the housing parts of filling in the external auditory meatus are provided with gas port.
This utility model structural design is joined wonderful, and it has following technological merit:
1, outward appearance novelty: this utility model is by normal person's external ear shaped design, wears attractive in appearance, itself and external ear and fits closely, not only stoped the intrusion of noise, and difficult drop-off is lost.On shell, establish hook, can fasten the chain thing so that carry.
2, gas port rationally is set, makes earplug when the Serb in ear, the part air of in ear can be derived, avoid making ear wall and tympanum to be under the compressing for a long time.
3, the setting of umbrella crown can not only well stop the intrusion of noise, and has overcome the existing earplug big drawback that takes up room in auditory meatus.
4, charge damping material in the housing, thereby more effectively subdue sound wave, also can be mixed with various color, to satisfy requirements of different users.
By above advantage, but about 35 decibels of this utility model noise attenuation.
This utility model accompanying drawing is a structural representation.
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model;
As shown in the figure: this utility model is by shell 1, umbrella crown 2, gas port 3 and the damping material 4 that is filled in the shell 1 constitute, shell 1 is according to the structural design of people's ear, be to shield from outside to inside successively with ears, the ears wheel, tragus, the identical housing preferably of external auditory meatus, carry out the transition in the external auditory meatus then, be provided with umbrella crown 2 (umbrella crown can have one or more) in its end, umbrella crown 2 can be designed to laminated structure, the effect of shell 1 is fixing earplug, stop noise to invade in ear, it is by latex, rubber or plastics are made, the material that other and contact skin are felt good also can, it should be noted that this material can not with shell 1 in dash the damping material 4 of irritating (as glycerol etc.) and chemical reaction take place or skin is had harmful effect.Umbrella crown 2 is fitted with the external auditory meatus wall, stops noise to invade in ear.In the middle of umbrella crown 2, establish the gas port 3 of the about 2mm of a diameter, this gas port 3 passes to the changeover portion of earplug, its effect is when earplug inserts, and the part air of in ear can be flowed out along passage, keeps tympanum pressure at both sides balance, like this, wear for a long time, can not make the people that uncomfortable sensation is arranged, when noise is invaded people's ear, most of process damping material is subdued to people's ear acceptable stage, and the noise that small part is invaded from the slit is stoped effectively by umbrella crown 2.Effect is more remarkable like this, compares with earmuff, and volume is much smaller, thereby makes it more extensive in industrial purposes.
