Abstract
A vacuum earplug belongs to a sound-proof device and mainly solves the problem that the traditional earplug is not adjustable in size and uncomfortable to wear. The vacuum earplug comprises an earplug body and is characterized in that the earplug body consists of a plug, a barrel and a piston, wherein the plug is a hollow elliptic air bag with one open end; one end of the barrel is inserted into the plug; and the piston is arranged inside the barrel. When the vacuum earplug is in use, the air in the plug is evacuated by the piston to reduce the volume of the plug; and after the plug is put into an ear canal, the piston is slowly pushed to aerate the plug to obtain a proper size. The vacuum earplug is convenient to adjust in volume and size, comfortable to wear and good in noise-resistance effect.
Description
Technical field
This utility model relates to a kind of sound arrester, specifically a kind of vacuum earplug.
Background technology
Noiseproof earplug is generally made by silica gel or low pressure bubble mould material, high resiliency polyester material.Closely contact with external auditory meatus after inserting auditory meatus, enter middle ear and internal ear, reach sound damping purpose with isolated sound, thus protection people's audition, but traditional earplug is harder, has worn tangible distending pain sense, is not suitable for sleep and uses.
The utility model content
The purpose of this utility model is to provide a kind of vacuum earplug, and this earplug has wears the function that comfortable, big I is regulated arbitrarily.
The technical scheme in the invention for solving the technical problem is: a kind of vacuum earplug, comprise earplug body, it is characterized in that, described earplug body is made of stopper, cylindrical shell and piston, described stopper is the hollow ellipse shape air bag of an end opening, described cylindrical shell one end inserts in the stopper, and described piston is located in the cylindrical shell.
The beneficial effects of the utility model are: stopper volume size adjustment is convenient, and is safe and reliable, wears comfortablely, and noise resistance is effective, can effectively improve sleep, protection audition etc.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 stopper, 2 cylindrical shells, 3 pistons.
The specific embodiment
As shown in Figure 1.A kind of vacuum earplug comprises earplug body, and described earplug body is made of stopper 1, cylindrical shell 2 and piston 3, the hollow ellipse shape air bag that described stopper 1 is an end opening, and described cylindrical shell 2 one ends insert in the stopper 1, and described piston 3 is located in the cylindrical shell 2.
During use, the air in the stopper 1 is extracted out, made stopper 1 smaller volume, put into after the auditory meatus piston 3 slowly advanced and make stopper 1 be inflated to suitable size by piston 3.This utility model stopper 1 volume size adjustment is convenient, wears comfortablely, and noise resistance is effective.
