Preferably, earplug body 11 includes two opposite inner ends and outer end, each ring packing arranged from outer end to inner end
The outer diameter of piece 12 is sequentially reduced.12 outer diameter of ring packing piece of 11 inner end of earplug body is small, is easily inserted into ear canal, reduces ear
Road be inserted by earplug after distending pain sense, moreover it is possible to guarantee sealing effect.
Preferably, each ring packing piece 12 is structure as a whole with earplug body 11, allows ring packing piece 12 and earplug body
It is fully sealed between 11, lift-off seal effect.Further, close to inner end annular closed piece and earplug body 11 it is interior
The end face smooth transition at end can be conducive to inner end one end and be inserted into ear canal, will not damage to ear canal.
The quantity of ring packing piece 12 outside earplug body 11 is not less than four, and multiple sealing can be formed in ear canal,
Guarantee the sealing effect having had.
The inner ring side of part or all of ring packing piece 12 is equipped with the deformation slot 14 being arranged along the border of earplug body 11,
There is deformation slot 14, can be convenient the inclination and distortion outward of ring packing piece 12, convenient for filling in ear canal, and reduces to ear canal wall
Constriction.
Preferably, the bottom surface section for deforming slot 14 is arc-shaped, and deformation slot 14 is located at corresponding ring packing piece 12 close to outer end
Side, be conducive to the inclination and distortion outward of ring packing piece 12.In other embodiments, deformation slot 14 may be alternatively located at corresponding annular
Side of the diaphragm seal 12 close to inner end.
In order to be conducive in earphone heads insertion earplug body 11, the inner ring of 11 outer end of earplug body is convenient for being equipped with chamfering.Earplug
The inner wall of ontology 11 is equipped with the card slot 13 being caught in for earphone heads or hearing aid head, allows between earphone heads and earplug body 11
It is fixedly connected.Preferably, card slot 13 is arranged along the border of 11 inner wall of earplug body, and allowing earplug to turn to each angle can be inserted into
Earphone heads.
In axial two adjacent ring packing pieces 12, close to 11 inner end of earplug body ring packing piece 12 it is radially-wide
Axial spacing between the degree ring packing piece 12 adjacent not less than corresponding position two, after earplug is filled in ear canal, annular is close
Mounting 12 can topple over outward, be pressed on adjacent ring packing piece 12 after toppling over, with the adjacent formation of ring packing piece 12
Sealing.
Preferably, each ring packing piece 12 equidistantly tilts in arrangement, the outer ring of each ring packing piece 12 outward, is formed oblique
Face, it is possible to reduce sense is scratched to ear canal when being inserted into ear canal.
In some embodiments, the section of each ring packing piece 12 is arc-shaped, and arches upward to inner end side, is further promoted
It is inserted into comfort when ear canal, is also conducive to after being inserted into ear canal form sealing with ear canal side wall, the earplug ring packing after insertion
Piece pours out, and multilayer, which is toppled over, to be formed opposition and prevent earphone or hearing aid from falling off.
In other embodiments, totally-enclosed earplug 1 is equally applicable on hearing aid, and totally-enclosed earplug 1, which can cover to be set to, to be helped
Listen in the earphone heads of device, promote leakproofness between ear canal after the earphone heads insertion ear canal of hearing aid, reach be completely closed every
The purpose of exhausted ambient noise.
Certainly, in other embodiments, earplug body 11 can also be solid construction, allow totally-enclosed earplug 1 is simple to be used to
It fills in ear canal and is sealed.
As shown in connection with fig. 3, in some embodiments, the molding die 2 of totally-enclosed earplug 1 includes cope plate 21, lower template
22 and the muti-piece sandwich plate 23 that is folded between cope plate 21, lower template 22.
Cope plate 21, lower template 22 two opposite faces on be respectively provided with molding 1 both ends of the surface of totally-enclosed earplug at
Type face 211, lower forming surface 221, and lower forming surface 221 is equipped with the lug boss for forming the inner hole of the earplug body 11 of tubular
222.In other embodiments, lug boss 222 can also be formed in forming surface 211, can also be in upper forming surface 211, lower molding
One section of lug boss 222 is respectively set on face 221, to form the inner hole of earplug body 11.
Sandwich plate 23 is equipped with the molding hole 231 being set in outside lug boss 222, and molding hole 231 is set in lug boss 222
Outside, and between lug boss 222 it is spaced, slot milling forms the side wall of earplug body 11.
The border of molding hole 231 is formed with the matrix band 232 of annular, and upper forming surface 211, lower forming surface 221, molding
Piece 232 is respectively separated setting, is separately formed ring packing piece 12 with slot milling.
Matrix band 232 can be in the thickness range of sandwich plate 23, and matrix band 232 can also be outwardly away from sandwich plate 23, energy
Two adjacent matrix bands 232 and matrix band 232 and upper forming surface 211, lower forming surface 221 are allowed to form annular diaphragm seal 12.
Smaller generally, due to earplug size, the matrix band 232 of each sandwich plate 23 will form a two adjacent ring packings
Clearance space between piece 12, the thickness of sandwich plate 23 also can be relatively thin.
Since sandwich plate 23 is relatively thin, but the interval width being generally thicker than between two adjacent ring packing pieces 12, it is preferable that
In muti-piece sandwich plate 23 in the present embodiment, positioned at middle layer one to three piece of sandwich plate 23 matrix band 232 place folder
In the thickness range of laminate 23, the matrix band 232 of other sandwich plates 23 is respectively to the direction of the sandwich plate 23 far from middle layer
Offset, allows two adjacent sandwich plates 23 that can form an annular closed piece 12, both ensure that molding, and also ensured mould strength.
According to the quantity of annular closed piece, the quantity of sandwich plate 23 can also be the other quantity of one or more than one.
For shaping and deformation slot 14, inner ring one end of matrix band 232 is equipped with the annular flange to central protuberance along border.
In addition, in some embodiments, upper forming surface 211, matrix band 232, lower forming surface 221 outer ring form downwards
Face 221 tilts, and molding annular closed piece 12 is allowed also to tilt to the outer end of earplug body 11.Upper forming surface 211, matrix band 232,
Lower forming surface 221 can also be parallel with sandwich plate 23.
It is as follows to form die sinking process:
When molding, the sandwich plate 23 of cope plate 21, lower template 22 and centre is laminated, and forms forming cavity in inside.It will molding
Raw material is injected into forming cavity, becomes earplug after intracavitary raw material cooling and shaping to be formed, then by cope plate 21, lower template 22 and
Intermediate 23 compartment of sandwich plate separates, and can deviate from from earplug, earplug can be removed.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
