Abstract
The utility model relates to an ear protector for aircraft passengers in which the airflow entering ears is utilized to keep basic balance of internal pressure and external pressure of ear drums. The utility model can reduce and eliminate effectively the pain and the tinnitus which the passengers feel when an aircraft takes off and lands. The utility model is characterized in that the ear protector is composed of a minisize electric blower 1, a ventilation rubber pipe 2, a ventilation switch 3, and earphones or earplugs 4. The ventilation switch 3 is arranged on the ventilation rubber pipe 2; one end of the ventilation rubber pipe is connected with the minisize electric blower 1, and the other end is connected with the earphones or the earplugs 4. The ear protector for the aircraft passengers has simple structure, low cost and easy application and is suitable for the fields, such as the aviation for civil use, the spaceflight, the high speed train, etc.
Description
This utility model relates to a kind of safety device in the aviation field, and it can alleviate and eliminate aircraft passenger's ear is done not feel like oneself when taking off and land protects (relaxing) ear device.
Aircraft is one of human maximum vehicles, yet take advantage of one of aircraft blemish in an otherwise perfect thing to be: aircraft is when taking off and landing, because the rapid variation of cabin internal gas pressure causes most of passenger's ear pain and tinnitus.Especially for the people who goes by air for the first time, the sense of this discomfort is even more serious.
Understand according to the retrieval of international and domestic relevant document and to aviation industry present situation in this regard, still do not have effective way and measure to alleviate at present and eliminate passenger's ear pain and tinnitus.By chewing gum, rub way such as ear with hands little through facts have proved its effect.State-of-the art passenger plane, as the airbus 320 in Europe, Boeing 757 grades of the U.S. increase the ways such as seal of cabin by the air conveying capacity in the increasing machine, have alleviated passenger's ear pain and tinnitus to a certain extent.For old-fashioned aircraft, especially former aircraft made in CCCP does not have effective way and measure to alleviate at present at all and eliminates passenger's ear pain and tinnitus.
The purpose of this utility model is to provide a kind of birdman's ear protector at the deficiencies in the prior art, be characterized in utilizing air-flow flowing in ear to keep the in a basic balance of pressure inside and outside the tympanum of ear, this balance guarantees that tympanum big distortion can not take place when taking off and land, thereby ear can not felt pain and tinnitus.And, in the ear throughput flow can also make the people feel relief, comfortable.
The purpose of this utility model is realized by following technical measures.
Birdman's ear protector are by miniature electric hair-dryer 1, ventilating glue tube 2, and ventilation switch 3 and earphone or earplug 4 are formed.Ventilating glue tube 2 is provided with ventilation switch 3, the continuous miniature electric hair-dryer 1 of ventilating glue tube one end, and the other end connects earphone or earplug 4.
Miniature electric hair-dryer 1 is by power-supply battery 5, and on and off switch 6 and fan 7 are formed.Power-supply battery 5 is by on and off switch 6 and fan 7 conductings or cut-out.
Miniature electric hair-dryer 1 can be crossed the automatic feed of music pipeline with the air communication on the aircraft, perhaps replaces with hand ear washing bulb 8 delivery airs.
When miniature electric hair-dryer 1 usefulness hand ear washing bulb 8 replaced, the ear washing bulb portion of chewing connected ventilating glue tube 2, ear washing bulb afterbody installing breather cheek valve 9.
The utlity model has following advantage:
Birdman's ear protector can alleviate effectively and eliminate and take off and ear is felt when landing pain and tinnitus, can also make the people feel relief, comfortable.And have simple in structure, easily manufactured, with low cost, those of ordinary skill and can both implement.It can not only be used for Aeronautics and Astronautics, can also be used for bullet train, crosses tunnel to eliminate train, and snub etc. are to similar discomfort that the passenger produced.
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
