Abstract
The utility model discloses a waterproof and dustproof sound-transmission earplug. An ePTFE expanded politef waterproof and dustproof air permeable film is filled in a flexible cavity body. One to nine column holes are evenly distributed in the flexible cavity body which is of a bullet head shape and provided with elastic rubber, plastic or silica gel materials, a sealing layer which is formed by bonding materials through solidification is arranged between the flexible cavity body and the ePTFE expanded politef waterproof and dustproof air permeable film, and the length of a whole plug body is larger than the length of the auditory meatus. According to the waterproof and dustproof sound-transmission earplug, the auditory meatus waterproof and dustproof problems produced when people wash hair, have a bath and swim and even produced in the daily life are solved, and the normal auditory sense is guaranteed not to be influenced.
Description
Technical field
This utility model relates to earplug, especially a kind of water proof and dust proof entrant sound earplug.
Background technology
People are in hair washing, when taking a shower and swimming, and auditory meatus is usually intake.Can produce sense of discomfort after the auditory meatus water inlet, serious problem is to cause ear disease such as otitis media easily, and ear disorder persons such as otitis media suffer untold misery in the face of hair washing, shower and swimming.In the daily life, auditory meatus can enter a large amount of dusts, also has foreign bodies such as small worm once in a while.
Existing for preventing that the earplug that auditory meatus is intake from adopting common material to process, reach by sealing means to prevent the into purpose of water.There is design defect in actual applications in this earplug, and is not ideal enough to the effect that prevents the auditory meatus water inlet; More since auditory meatus sealed after, audition almost loses, and causes new all inconvenience that do not accommodate.Owing to have a strong impact on audition, can't use in daily life at all.
The utility model content
Problem to be solved in the utility model is the deficiencies in the prior art parts, namely adopt common material and design sealed ear canal, user can't be heard outside sound, a kind of water proof and dust proof entrant sound earplug is proposed, in flexible cavity, fill ePTFE varicosity politef water proof and dust proof ventilated membrane, add with the flexible cavity with special tectonic and combine closely, just can be implemented in strictness and prevent hair washing, auditory meatus water inlet when taking a shower and swimming, keep the normal unobstructed auditory meatus that enters of sound and pure air simultaneously, foreign bodies such as the dust in the daily life and small worm are effectively stoped.
This utility model is by realizing by the following technical solutions:
Manufacture and design water proof and dust proof entrant sound earplug, comprising: fill ePTFE varicosity politef water proof and dust proof ventilated membrane in the flexible cavity; 1～9 post hole evenly distributes in rubber-like rubber, plastic cement or silica gel material, the bullet-headed flexible cavity; Be provided with the sealant that is solidify to form by bonding material between flexible cavity and the ePTFE varicosity politef water proof and dust proof ventilated membrane; The length of whole cock body is given prominence to auditory meatus.
This utility model is owing to select for use existing functions of waterproof and dustproof that the ePTFE varicosity politef water proof and dust proof ventilated membrane of ventilative effect is arranged again, be equipped with corresponding flexible cavity and reasonably structure and compound measure thereof, just can make earplug strictness prevent auditory meatus water inlet, effectively stop foreign bodies such as dust and small worm in, keep auditory meatus entrant sound and ventilative.
This water proof and dust proof entrant sound earplug is changed the method that past pure relies on physics to stop up, the rubber that water proofing property is strong, plastic cement or silica gel material are as flexible cavity, the superpower water proof and dust proof and the airing function that utilize the ePTFE varicosity politef of effective diameter 0.10～7.00um to have, when realizing thoroughly preventing the auditory meatus water inlet, the blocking-up diameter is greater than the floating dust more than 0.10～7.00um, the more important thing is, ePTFE varicosity politef air permeability and good has guaranteed the auditory meatus inside and outside air pressure balance, does not influence the normal propagation of sound.Even 1～9 the post hole that distributes helps the rational deployment of water proof and dust proof ventilated membrane in the flexible cavity.The bullet-headed flexible cavity of rubber-like can be according to the size of auditory meatus, the insertion length that the depth is grasped earplug flexibly, and strengthen its sealing effectiveness.The sealant that is solidify to form by bonding material between flexible cavity and the ePTFE varicosity politef water proof and dust proof ventilated membrane makes has splendid composite effect between the earplug member.The outstanding auditory meatus of the length of whole cock body makes it and can insert easily and extract.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the axonometric chart according to a kind of concrete structure that the utility model proposes.
Fig. 2 is the cross-sectional view according to a kind of concrete structure that the utility model proposes.
Fig. 3 is the sketch map that shows substantial connection between this utility model and the auditory meatus.
(1) is flexible cavity among the figure, and (2) are ePTFE varicosity politef water proof and dust proof ventilated membrane, and (3) are the post hole, and (5) are sealant.
The specific embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
Water proof and dust proof entrant sound earplug is formed (5) by flexible cavity (1), ePTFE varicosity politef water proof and dust proof ventilated membrane (2) and sealant; EPTFE varicosity politef water proof and dust proof ventilated membrane (2) is filled in the flexible cavity (1); 5 post holes (3) evenly distribute in rubber-like rubber, plastic cement or silica gel material, the bullet-headed flexible cavity (1); Be provided with the sealant (5) that is solidify to form by resene between flexible cavity (1) and the ePTFE varicosity politef water proof and dust proof ventilated membrane (2); The length of whole cock body is given prominence to the about 0.5cm of auditory meatus.
People hair washing, take a shower and swimming before, even in daily life, all can use water proof and dust proof entrant sound earplug.During use, pinch the afterbody of water proof and dust proof entrant sound earplug, its front end is inserted auditory meatus slowly to the appropriate degree of depth.After the use, the afterbody that pinches cock body is extracted gently and is got final product.
Water proof and dust proof entrant sound earplug had both solved the auditory meatus water proof and dust proof problem in people's hair washings, shower and swimming even the daily life, and guaranteeing does not again influence normal audition, simple in structure, also economical and practical.
