, so as to enable a person to obtain quiet rest or working environment.The noise-proofing ear with elastic umbrella-shaped structure of the prior art
Plug, is made using the preferable elastic material of pliability, but it is solid construction, and elastic deformability is small, is worn for a long time
Dai Hou, ear have stronger constriction, cause ear's distending pain, and use is uncomfortable.
Utility model content
The technical problems to be solved in the utility model is：In order to overcome it is above-mentioned present in earplug elastic deformability is small asks
Topic, there is provided a kind of hollow earplug, has good soundproof effect, elasticity is good, using comfortable.
Technical solution is used by the utility model solves its technical problem：A kind of hollow earplug, including using flexible
Property earplug body made of preferable elastic material, the earplug body is provided with the hollow structure of cavity for middle part, including
Pleasant stem, be arranged on pleasant stem top head, be arranged on pleasant stem outer at least one layer of umbrella leaf and setting
In the plunger of pleasant stem tail end；The tail end of the pleasant stem is provided with the opening connected with cavity；The plunger installation
In opening.
Preferably, the plunger includes the cylinder being adapted to opening and the Handheld Division for being arranged on cylinder tail end.Should
Handheld Division is spherical structure, its good appearance, convenient and practical.
Preferably, the head is pyramidal structure.Facilitate pleasant, increase comfort level.
Preferably, the head is spherical structure.Facilitate pleasant, increase comfort level.
Preferably, the thickness of the umbrella leaf is gradually thinned from middle part to edge.Closely it is affixed with ear, reduces anti-make
Firmly, using comfortable.
Preferably, the umbrella leaf is 2~3 layers.Multi-layer umbrella leaf, improves soundproof effect.
Preferably, the earplug body is made of silica gel.Silicone elastomer is good, easy to clean.
The beneficial effects of the utility model are：A kind of hollow earplug, during earplug body is integrally formed by silica gel material and is
Hollow structure, its elasticity greatly enhance, and deformability is big, facilitate pleasant, have multiple umbrella leaves, the thickness of umbrella leaf from middle part to edge by
It is decrescence thin, closely it is affixed with ear, reduces reaction force, using comfortable；Live to be open by plunger seal, improve the bullet of earplug body
Property.
