Abstract

The utility model relates to an earplug for protecting ears during flying. The earplug adopts a drum-like structure with the middle part thicker and two ends tapering off, comprises an in-ear part, a handle part and a cavity part, and is integrally made of flexible materials, four ring-shaped projected parts are arranged in the in-ear part along the periphery of a drum wall and are increased in sequence from inside to outside. Threads are formed on the outer ring of the handle part to increase the friction force caused by gripping. The cavity part is a cavity channel allowing air to pass, and has a porous dense structure in the middle, so that the airflow can be blocked, and when an airplane flies away and falls, the internal and external pressure difference of an ear canal can be relieved through the porous dense structure.

Description

A kind of flight earflap earplug

Technical field

This utility model belongs to a kind of health care products, relates in particular to a kind of being used at the device of taking off, the landing process is protected ear.

Background technology

Airplane is taken off or when descending, ear produce feel bad feel it is universal phenomenon.Feeling in ear discomfort or pain during airplane, is that middle ear inner and outer air pressure disequilibrium causes.Some pilot and stewardess suffer from " aerotitis ", because long-term flight causes.By the tympanum sealing, the middle ear chamber communicates with pharyngeal by pharyngotympanic tube between people's middle ear and the external auditory meatus, and the pressure of middle ear room air is to keep equilibrated by pharyngotympanic tube and atmospheric pressure.Thereby pharyngotympanic tube itself is very not unobstructed, is potential pipeline at ordinary times, when catch cold, when illness such as pharyngitis or nasopharynx part have the inflammation edema, pharyngotympanic tube is just more obstructed.When aircraft rises, ambient atmosphere pressure reduces with height, middle ear are intrinsic pressure higher relatively, tympanum expands to external auditory meatus, therefore can cause not accommodate pain that fly at certain altitude up to aircraft, intratympanic gas is discharged a part by pharyngotympanic tube, after the middle ear internal pressure and the external world reached balance, sense of discomfort and pain just can disappear.During aircraft landing, external and internal pressure occurs oppositely unbalance again, the pressure height of outside, and intratympanic pressure is low, tympanum is pressed towards middle ear, otopiesis occurs, can cause sense of discomfort and pain equally, up to air through pharyngotympanic tube enter middle ear a little, external and internal pressure reaches balance, symptom just can disappear.

In order to alleviate the discomfort of ear, adopt usually and do swallowing act, motion soft palate, motion lower jaw or pinch action such as nasal respiration, impel pharyngotympanic tube open, unimpeded, make the middle ear inside and outside air pressure balance as early as possible.

But airplane, the Overweight and Zero Gravity when taking off landing still can be brought frightened sensation to the people, makes man-hour regular meeting forget what this does.

Summary of the invention

This utility model provides a kind of earplug, and it is simple in structure, and is practical, by air, by plane the time, its plug in ear, can be alleviated the discomfort of ear effectively.

To achieve these goals, this utility model has adopted such technical scheme: it is that a centre is thick, to the structure of the tapered similar drum type in two ends.Be divided in ear part, handle portion, chamber portion, three ingredients.Its integral body all is to be made by softish material.The part that the in ear part has four annulars to protrude all around along the drum wall from inside to outside, increases successively.There is spiral lamination the handle portion outer ring, the frictional force during in order to the increase grasping.Chamber portion is the tract that air passes through, and at mid portion a porous compact texture is arranged, and it can block air-flow, and alleviation is taken off, the auditory meatus external and internal pressure when landing is poor.

The beneficial effects of the utility model are, it plays the blocking-up air-flow by the special construction in the earplug, alleviate take off, the auditory meatus external and internal pressure when landing is poor.

Description of drawings

Fig. 1 is a generalized section of the present utility model.

1 porous compact texture wherein, 2 in ear parts, 3 chamber portions, 4 handle portions.

The specific embodiment

Be described further below in conjunction with accompanying drawing.

As shown in the figure, it is that a centre is thick, to the structure of the tapered similar drum type in two ends.Be divided in ear part 2,

handle portion

4,3, three ingredients of chamber portion.Its integral body all is to be made by softish material.The part that the in ear part has four annulars to protrude all around along the drum wall from inside to outside, increases successively.There is spiral lamination the handle portion outer ring, the frictional force during in order to the increase grasping.Chamber portion is the tract that air passes through, and at mid portion a porous compact texture 1 is arranged, and it can block air-flow, and alleviation is taken off, the auditory meatus external and internal pressure when landing is poor.

The above only is this utility model preferred embodiment, is not this utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, and equivalent variations and modification still belong in the scope of technical solutions of the utility model.

Claims

1. flight earflap earplug, it is divided in ear part, handle portion, chamber portion, and three ingredients is characterized in that it is that a centre is thick, and to the structure of the tapered similar drum type in two ends, integral body all is to be made by softish material.

2. a kind of flight earflap earplug according to claim 1 is characterized in that the part that the in ear part has four annulars to protrude along the drum wall all around, from inside to outside, increases successively.

3. a kind of flight earflap earplug according to claim 1 is characterized in that there is spiral lamination the handle portion outer ring.

4. a kind of flight earflap earplug according to claim 1 is characterized in that chamber portion is the tract that air passes through, and has a porous compact texture at mid portion.
