Description

Water sound insulation earplug

Technical Field

The utility model relates to an earplug technical field especially relates to a water sound insulation earplug.

Background

Earplug on the existing market is noise control earplug, generally by silica gel or low pressure bubble mould material, high elasticity polyester material is made, insert behind the duct with external auditory canal in close contact with, get into well ear and inner ear with isolated sound, reach syllable-dividing effect, but the bending of duct inner wall is soft, the rebound effect of ordinary earplug rule can make the ear appear that the duct is red and swollen and earplug gas leakage even pain in sleeping, the oppression of sleeping on one's side, can not reach long-term comfortable and quiet effect, and use for a long time the rebound effect weaken so that can't use repeatedly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving and having the crooked softness of duct inner wall among the prior art, the rebound effect of ordinary earplug rule can make the ear appear that the duct is red and swollen and earplug gas leakage even pain in sleeping, and the oppression of sleeping on one's side can not reach long-term comfortable and quiet effect, and uses the shortcoming that the rebound effect weakens so that can't use repeatedly of being of a specified duration, and the earplug that gives sound insulation of a water that provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a water sound insulation earplug, includes the inner shoe, the upper and lower both ends of inner shoe are the arc setting, the outside cover of inner shoe is equipped with the outer protective layer, and isolated each other between the outside of inner shoe and outer protective layer, be provided with the gap between outer protective layer and the inner shoe, this the gap intussuseption is filled with the water, the outside lower extreme of outer protective layer is provided with coupling mechanism, the outer protective layer includes the polyester fiber layer, the internal surface complex of polyester fiber layer bonds and has the rete that blocks water, the surface complex of polyester fiber layer bonds and has the natural latex layer, the thickness proportion between natural latex layer, polyester fiber layer and the rete that blocks water is 1: 1: 2.

preferably, the connecting mechanism comprises an elastic ring fixedly installed on the outer surface of the natural latex layer, an elastic belt is fastened on the inner side of the elastic ring, and a pull ring is fastened at one end of the elastic belt far away from the elastic ring.

Preferably, a silica gel layer is compositely bonded on the outer surface of the inner supporting block.

Preferably, the sum of the thicknesses of the natural latex layer, the polyester fiber layer and the water blocking film layer is 0.9 mm.

The utility model provides a pair of water sound insulation earplug, beneficial effect lies in: this water gives sound insulation in earplug water sound insulation effect is superior to silica gel far away, and water does not have the shape, gets into the duct after, both can closely laminate with anomalous duct, can not produce the swelling again and feel, can relapse a lot of and be utilized, consequently is favorable to promoting.

Drawings

Fig. 1 is a schematic structural view of a water sound insulation earplug according to the present invention.

Fig. 2 is a schematic structural view of a water sound insulation earplug according to the present invention.

In the figure: the water body 1, the silica gel layer 2, the outer protective layer 3, the natural latex layer 31, the polyester fiber layer 32, the water blocking film layer 33, the inner support block 4, the elastic ring 5, the elastic belt 6 and the pull ring 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-2, a water sound insulation earplug, including interior supporting shoe 4, the upper and lower both ends of interior supporting shoe 4 are the arc setting, the outside cover of interior supporting shoe 4 is equipped with outer protective layer 3, and isolated each other between the outside of interior supporting shoe 4 and outer protective layer 3, be provided with the gap between outer protective layer 3 and the interior supporting shoe 4, this gap intussuseption is filled with water 1, outer protective layer 3 includes polyester fiber layer 32, polyester fiber layer 32's the compound rete 33 that blocks water that bonds of internal surface, polyester fiber layer 32's the compound bonding of external surface has natural emulsion layer 31, polyester fiber layer 32 and the thickness proportion that blocks water between the rete 33 are 1: 1: 2, this earplug prevents in the duct, because the mobility of water and outer protective layer 3 have fine deformation effect, the sound insulation effect of utilization water is superior to silica gel far away, and water does not have the shape, gets into behind the duct, both can closely laminate with anomalous duct, can not produce the swelling again and feel, can relapse a lot of and be utilized, and the smooth injury to interior duct in natural latex surface reduces simultaneously.

The sum of the thicknesses of the natural latex layer 31, the polyester fiber layer 32 and the water blocking film layer 33 is 0.9 mm, the thickness is 0.9 mm, and the natural latex layer can effectively realize water insulation and can be well attached to the inner wall of the auditory canal.

Example 2

Referring to fig. 1-2, the difference between this embodiment and embodiment 1 is that the outer lower end of the outer protection layer 3 is provided with a connection mechanism, the connection mechanism includes an elastic ring 5 fixedly mounted on the outer surface of the natural latex layer 31, an elastic band 6 is fastened to the inner side of the elastic ring 5, and a pull ring 7 is fastened to one end of the elastic band 6 far away from the elastic ring 5, when the earplug is taken down, the earplug can be taken out from the ear canal by applying external force to the elastic band 6 by the pull ring 7 held by a wearer, so as to avoid the problem that the ear canal is damaged due to the contact between fingers and the ear canal.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
