Abstract
The utility model relates to the technical field of flying supplies, in particular to decompression earplugs. The decompression earplugs comprise earplug bodies and are characterized in that small holes are arranged at two ends of the earplug bodies, and hollow air chambers are arranged in the earplug bodies. The decompression earplugs have the advantages that when the earplug bodies are put into ears, the air pressure flow changing rapidly cannot enter ears directly, and only a small amount of air is allowed to enter the air chambers through the small holes at inlets of the earplug bodies, so that the air flow is slowed, and the outside and inside air pressure difference of ears is reduced; and as only a small amount of air is allowed to reach eardrums, so that the insides of ears can balance pressure at high altitudes, too much pressure produced due to the rapidly-changing air pressure can be prevented from being exerted on functions of ear eustachian tubes, the eustachian tubes can perform normal functions, and symptoms such as discomfort of ears, tinnitus and otalgia caused by changes of the air pressure and the air flow are relieved.
Description
This utility model relates to flight articles for use technical field, is specifically related to a kind of decompression earplug
Background technology
Ubiquitous earplug in the market, it is the earplug of spongy body, just be used for clogging ear, ear can not be breathed freely, basically just play the effect of sound insulation, the eustachian tube function of ear is because fast-changing air pressure produces too big pressure, the function that pharyngotympanic tube can not be brought into normal play, thereby symptoms such as the ear discomfort that causes, tinnitus, otalgia.The spongy body earplug is short service life simultaneously, is difficult for reusing, and Ben Ersai is reusable, and service time is long.
The utility model content
The purpose of this utility model is to provide a kind of decompression earplug in order to overcome shortcoming of the prior art, can effectively releive because of the air pressure variations in flow, tympanum is produced the technical problem of uncomfortable influence.
For realizing that to state purpose this utility model adopts following technical scheme:
A kind of decompression earplug comprises earplug, it is characterized in that, the two ends of described earplug are provided with aperture, and the inside of earplug is provided with hollow air chamber.
The beneficial effects of the utility model are: earplug is worn into ear, allow fast-changing air pressure stream can directly not enter ear, aperture by the earplug porch only allows a spot of air admission air chamber, air-flow slows down, outside and inner ear air pressure difference have been reduced, by allowing a spot of air to reach tympanum, make ear inside at high-altitude energy equalizing pressure, thereby make the eustachian tube function of ear can not produce too big pressure because of fast-changing air pressure, the function that pharyngotympanic tube can be brought into normal play reaches the ear discomfort of releiving and causing because of the air pressure variations in flow, tinnitus, symptoms such as otalgia.Have the function that reduces noise simultaneously.
Description of drawings
Figure 1 shows that the front view of a kind of earplug that reduces pressure that this utility model provides;
Figure 2 shows that the left view of a kind of earplug that reduces pressure that this utility model provides;
Figure 3 shows that the right view of a kind of earplug that reduces pressure that this utility model provides.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is further elaborated.
To Fig. 3, the figure shows the structure of a kind of earplug that reduces pressure that this utility model provides referring to Fig. 1.For convenience of explanation, only show the relevant part of this utility model.
A kind of decompression earplug comprises earplug 1, it is characterized in that, the two ends of described earplug 1 are respectively equipped with aperture 2A and 2B, and the inside of earplug 1 is provided with hollow air chamber 3.
The beneficial effects of the utility model are: earplug is worn into ear, allow fast-changing air pressure stream can directly not enter ear, aperture by the earplug porch only allows a spot of air admission air chamber, air-flow slows down, outside and inner ear air pressure difference have been reduced, by allowing a spot of air to reach tympanum, make ear inside at high-altitude energy equalizing pressure, thereby make the eustachian tube function of ear can not produce too big pressure because of fast-changing air pressure, the function that pharyngotympanic tube can be brought into normal play reaches the ear discomfort of releiving and causing because of the air pressure variations in flow, tinnitus, symptoms such as otalgia.
