Abstract
The utility model discloses a waterproof earplug, comprising a sealing gas bag connected with an air-storage gas bag through a linkage unit, wherein, a breather hole is arranged at the middle of the linkage unit; the breather hole is communicated with the gas paths of the sealing gas bag and the air-storage gas bag; a groove is arranged at one end of the breather hole facing the air-storage gas bag; a core bar passes through the breather hole; two ends of the breather hole respectively extend into the sealing gas bag and the air-storage gas bag; the gap is available between the breather hole and the core bar; a flange is arranged at one end of the core bar penetrated into the sealing gas bag; a post rod is arranged at the external end of the flange; a packing ring is arranged between the internal end of the flange and the breather hole; a spring base is arranged at one end of the core bar facing the air-storage gas bag; a spring is arranged on the spring base; the other end of the spring is propped on the groove. As the utility model adopts a high elasticity air bag actively attached on the meatus auditorius inwall, thereby realizing complete sealing, preventing water from entering into internal ears, and simultaneously providing convenience for users to adjust comfortable degree according to the feeling, and avoiding discomfortable feeling brought by the earplug made of the traditional material.
Description
Technical field
This utility model belongs to the health protection technical field, relates to a kind of waterproof earplug.
Background technology
The people is when contacting with water, and sordid water enters auditory meatus, can cause external ear, middle ear inflammation, produces obvious pain, and severe patient can cause that ear is suppurated, temporary dysaudia etc.In order to prevent that water enters auditory meatus when swimming, diving or the bathing, the earplug that is used for waterproof now generally adopts soft material to make the column integral structure, fill in external auditory meatus during use, utilize the elastic compensating earplug of earplug self and the slit between the ear canal wall, reach the purpose that anti-sealing enters auditory meatus.
But existing waterproof earplug has tangible disadvantage, and at first this earplug size specification is few, and different crowd is poor for applicability, the part user can produce sense of discomfort in use, cause the auditory meatus distortion, cause ear that foreign body sensation is arranged, may damage ear canal wall and tympanum; Secondly,, still have low amounts of water once in a while and enter, do not reach thorough good waterproof effect owing to can not guarantee to fit fully with external auditory meatus.
Summary of the invention
The purpose of this utility model is, a kind of waterproof earplug is provided, the sense of discomfort when solving existing earplug and using, and earplug seals halfway problem.
The technical solution of the utility model is, a kind of waterproof earplug, characteristics are that pressure bladder is connected with the gas storage air bag by connector, the centre of connector has valve vertically, the gas circuit of valve communication seals air bag and gas storage air bag, valve is provided with groove towards an end of gas storage air bag, one core bar passes valve, the two ends of core bar are stretched into respectively in pressure bladder and the gas storage air bag, leave the space between valve and the core bar, the end that core bar gos deep into pressure bladder is provided with flange, the outer end of flange is provided with push rod, is provided with sealing ring between the inner of flange and the valve, and core bar is provided with spring base towards an end of gas storage air bag, spring is installed on the spring base, and the other end of spring withstands on the groove.
Described spring base is located by pin,
Described spring base also can be by the end generation deformation location of core bar.
The beneficial effects of the utility model are, use when swimming, diving or bathing, can prevent that thoroughly sealing enters auditory meatus, and feel comfortable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure 1, pressure bladder, 2, push rod, 3, sealing ring, 4, valve, 5, core bar, 6, spring, 7, spring base, 8, the gas storage air bag, 9, connector, 10, flange, 11, groove, 12, pin.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described further.
As shown in FIG., pressure bladder 1 is connected with gas storage air bag 8 by connector 9, the centre of connector 9 has valve 4 vertically, the gas circuit of valve 4 communication seals air bags 1 and gas storage air bag 8, valve 4 is provided with groove 11 towards an end of gas storage air bag 8, one core bar 5 passes valve 4, the two ends of core bar 5 are stretched into respectively in pressure bladder 1 and the gas storage air bag 8, leave the space between valve 4 and the core bar 5, the end that core bar 5 gos deep into pressure bladder 1 is provided with flange 10, the outer end of flange 10 is provided with push rod 2, be provided with sealing ring 3 between the inner of flange 10 and the valve 4, core bar 5 is provided with spring base 7 towards an end of gas storage air bag 8, and spring 6 is installed on the spring base 7, and the other end of spring 6 withstands on the groove 11.
This utility model in use, pressure bladder 1 is filled in the external auditory meatus appropriate depth, with hands extruding gas storage air bag 8, pressure in the gas storage air bag 8 increases, during pressure in having surpassed pressure bladder 1, because the effect of draught head, the gas of gas storage air bag 8 promotes core bar 5 to pressure bladder 1 one lateral movements, make and produce the slit between sealing ring 3 and the valve 4, gas flow in the pressure bladder 1 by the gap of core bar 5 with valve 4 inwalls, make it to expand, thereby make pressure bladder 1 ear canal wall of can tightly fitting, play the effect of sealed ear canal.The big I of the pressure of pressure bladder 1 is adjusted voluntarily according to the comfort level of user.After realizing sealing, unclamp gas storage air bag 8, core bar 5 under the responsive to axial force that spring 6 produces to 8 one lateral movements of gas storage air bag, slit closure between sealing ring 3 and the valve 4, stop gas to flow out pressure bladder 1, and keep pressure bladder 1 to be swelling state all the time, and tightly fit with ear canal wall, realize waterproof completely.After use finishing, extract earplug, pinch push rod 2 in the pressure bladder 1 with hands, to the pulling of pressure bladder 1 one ends, drive core bar 5 and move, make between sealing ring 3 and the valve 4 and produce the slit, the gas of pressure bladder 1 flow in the gas storage air bag 8, reach the pressure at two ends balance after, get final product.This utility model has overcome the deficiency of conventional waterproof earplug, adopts the air sac sealing auditory meatus, the high resiliency air bag ear canal wall of initiatively fitting, thus realize sealing completely, reached the purpose that anti-sealing enters into internal ear.The present invention simultaneously meets the ergonomics principle, and user can be adjusted comfort level, the sense of discomfort of having avoided traditional earplug to cause according to sensation.This utility model not only waterproof effect is remarkable, can also be applied in noiseproof occasion.
