Abstract

The utility model relates to an ear plug. The ear plug comprises a stopping piece part and a hollow tubular part, wherein the stopping piece part is made of elastic materials such as tuber in a uniform mode, and the hollow tubular part comprises a spiral line on the outer surface and is used for being inserted in to an ear. Due to the flexibility and light weight, the ear plug can be used comfortably, and the hollow tubular part has the advantage that a user can hear words of other people when wearing the ear plug, so that the user can communicate with other people without the need of taking out the ear plug.

Description

Earplug

Technical field

This utility model relates to a kind of earplug, and particularly a kind of have stop part partly and the earplug of hollow tubular portion, and this hollow tubular portion has helix along its outer surface.

Background technology

Earplug makes it avoid excessive noise for the protection of people's ear, and can prevent that sealing or other liquid and solid enter auditory meatus.But conventional earplug can be formed by the Cotton Gossypii that is impregnated with the waxy substance with forming characteristic, cotton-wool or cotton fiber.These routines have the tendency that easily comes off from ear based on the earplug of cloth.

Other conventional earplug can be formed by rubber and the rubber-like substance that can carry out strain.Such rubber earplug can reside in the ear than the earplug based on cloth better, but comfortableness is relatively poor for wearing for a long time, this is because these rubber earplugs elastically deformable only, and be configured as may be not identical with ear canal shapes circular cross section, therefore be not the cooperation of custom.

And some conventional earplug is by Unitarily molded and made by foam or silicone, and is solid.These earplugs can comprise the part that diameter is more smaller than auditory meatus, in order to be inserted in the ear.Such part is solid and abundant, and very hard, therefore, can hurt the tympanum of user.And user can not hear that when wearing these earplugs other people speak, and therefore are not easy to exchange with other people when wearing earplug.

The utility model content

Therefore, a purpose of the present utility model (technical problem to be solved) is to propose a kind ofly to wear comfortable and do not injure the earplug of user tympanum.

Another purpose of the present utility model (technical problem to be solved) is to propose a kind of earplug that can keep user can hear when wearing earplug.

In addition, another purpose of the present utility model (technical problem to be solved) is to propose a kind of earplug of producing with single size, in order to correctly and cosily cooperate the tympanum size of most of user.

To achieve these goals, in preferred embodiments, comprise stop part part and hollow tubular portion according to earplug of the present utility model.Described stop part partly forms its diameter greater than auditory meatus, in order to the auditory meatus entrance is sealed fully, and enters ear or leaves ear to handle described earplug as handle.Described hollow tubular portion forms that to have a sealing most advanced and sophisticated and along the helix of its outer surface, and described hollow tubular portion has the length that is enough to extend in the auditory meatus when user is worn described earplug.Described stop part part and described hollow tubular portion are made in heterogeneity by the synthetic rubber of the synthetic resin of natural rubber or any abundant softness.

In other words, this utility model provides a kind of earplug, comprising:

Stop part part, described stop part partly form its diameter greater than auditory meatus, and

Hollow tubular portion, described hollow tubular portion form that to have a sealing most advanced and sophisticated and along the helix of its outer surface, and when user is worn described earplug, described hollow tubular portion has is enough to extend to the interior length of auditory meatus.

In above-mentioned earplug, preferably, described stop part part and described hollow tubular portion form in heterogeneity.

In above-mentioned earplug, preferably, described earplug is made by the synthetic rubber of the synthetic resin of natural rubber or any abundant softness.

In above-mentioned earplug, preferably, the diameter of described hollow tubular portion is wider than be used to the diameter that extends to the user auditory meatus in the auditory meatus.

Pass through said structure, this utility model can be achieved as follows useful technique effect: earplug of the present utility model is worn comfortable and is not injured the user tympanum, perhaps can also keep user can hear that when wearing earplug other people speak, thereby can under the condition of not pulling out earplug, exchange with other people, perhaps can also single size production and be fit to the tympanum size of most of user.

The specific embodiment

With reference to figure 1-4, earplug comprises stop part part 1 and hollow tubular portion 2.Stop part part 1 forms to be had round-shapedly, and this round-shaped diameter is greater than auditory meatus, in order to the auditory meatus entrance is sealed fully, and enters or leave ear as handle to handle earplug.Tubular portion 2 forms cephalocaudal hollow hole 3 with sealing most advanced and sophisticated 4 and along the helix 5 of its outer surface, and when user is worn earplug, and tubular portion 2 has and is long enough to extend to the interior length of auditory meatus.Described stop part part 1 and hollow tubular portion 2 consists of earplug of the present utility model, and made in heterogeneity by the synthetic rubber of the synthetic resin of natural rubber or any abundant softness.

Below with reference to Fig. 5, it has shown according to earplug of the present utility model and has been worn in the auditory meatus.Hollow tubular portion 2 with its helix 5 is received within the common auditory meatus of auditory meatus (ordinary canal of the ear canal), thereby anti-sealing or other liquid or solid enter in the auditory meatus.Earplug of the present utility model be lightweight and can produce in batches.

Claims

1. an earplug is characterized in that, comprising:

2. earplug according to claim 1 is characterized in that, described stop part part and described hollow tubular portion form in heterogeneity.

3. earplug according to claim 1 and 2 is characterized in that, described earplug is made by the synthetic rubber of the synthetic resin of natural rubber or any abundant softness.

4. earplug according to claim 1 and 2 is characterized in that, the diameter of described hollow tubular portion is wider than be used to the diameter that extends to the user auditory meatus in the auditory meatus.

5. earplug according to claim 3 is characterized in that, the diameter of described hollow tubular portion is wider than be used to the diameter that extends to the user auditory meatus in the auditory meatus.
