Embodiment Construction

[0026] The invention provides a liquid-injection sound-reducing earplug, which comprises a plug body and an earplug main body 1, the plug body is connected with the earplug main body 1, and the plug body is a cavity structure filled with liquid.

[0027] The main body of the earplug is an integrated structure, and a connected cavity is formed inside, the front end is a hollow straight channel 16, the rear end is a cylindrical cavity, and the front end and the rear end are smooth arc structures;

[0028] The plug body includes a plug head 20 and a plug body 2 , the plug body 2 is embedded in the cavity of the earplug body 1 , and the plug head 20 is set on the head of the earplug body 1 through the hollow straight channel 16 on the earplug body 1 .

[0029] Two sets of buckles are arranged on the inner wall of the cylindrical cavity of the earplug main body 1, and the two sets of buckles are symmetrical through the center of the circle. Each set of buckles includes a first buckl...

Abstract

The invention, which belongs to the field of articles of daily use, provides a liquid injection type silencing earplug comprising a plug body and a main earplug body. The plug body and the main earplug body are connected. The plug body has a cavity structure filled with liquid. The plug body is filled with liquid, so that the good sound insulation effect is realized. A silicone ring is arranged and enables the earplug to be fixed in the auditory meatus by extruded deformation; and the sound insulation effect can be enhanced by using the silicone ring. Because of cooperation of buckles and clamping edges, a T-shaped pressing plate rotates based on the comfortable level of the user to adjust the embedding tightness degree of the plug body into the auditory meatus. With an elastic sleeve ring and a cylindrical rubber band, resilience can be provided by the elastic sleeve ring and the cylindrical rubber band when the T-shaped pressing plate rotates to realize buckling or releasing, so that the buckling or releasing process becomes convenient. Besides, for the sake of convenience, the invention also provides a rotating and pressing block cooperating with the T-shaped pressing plate.

Description

technical field [0001] The invention belongs to the field of daily necessities, and relates to an earplug, in particular to a liquid injection type sound-reducing earplug. Background technique [0002] The existing sound-proof earplugs mainly use the sound-proof effect of the sponge, and then shape the shape of the sponge according to the structural characteristics of the ear canal, and then improve the material and type of the sponge according to the needs of expansion and deformation, so that the sponge has elastic recovery performance. Or use elastic materials such as silica gel in combination with sponges, but there are still defects. Specifically, these raw materials are not easy to clean, and the recovery and deformation durability is not good. The most important point is that the sound insulation and sound reduction effect is still not ideal. [0003] The patent "sound-proof earplug" (notification number: 201330365063.3) disclosed in the prior art uses sponge as a raw...
