Description
Technical field
This utility model relates to a kind of ear muff, is specifically related to a kind of vacuum sound insulation ear muff.
Background technology
At present, the ear protection device great majority that people use in noisy environment are rubber earplugs, these earplug good springiness, and can insert the external auditory meatus of people well, this earplug can weaken sound wave to a certain extent, protection tympanum.But this earplug exists a lot of problem, wear earplug for a long time and external auditory meatus can be made uncomfortable, even injure external auditory meatus.When external sound intensity reaches high-decibel, necessary jam-pack earplug, can increase like this, and soundproof effect can be very low to the injury of external auditory meatus.
Utility model content
(1) technical problem that will solve
In order to overcome prior art deficiency, a kind of vacuum sound insulation ear muff is now proposed, not only effective under low decibel environment, under superelevation decibel environment, still there is good soundproof effect, ear muff parts discord external auditory meatus contact simultaneously, so can not damage external auditory meatus, structure is simple, convenient manufacture and use.
(2) technical scheme
Of the present utility modelly to be achieved through the following technical solutions: the utility model discloses a kind of vacuum sound insulation ear muff, comprise Earcap supporter, ear muff connector, vacuum chamber housing body and vacuum chamber inner housing, described ear muff connector is flexibly connected with Earcap supporter, described vacuum chamber housing body and vacuum chamber inner housing are nest shape and are adhesively fixed in the same way and form a vacuum chamber between, the external side of described vacuum chamber housing is provided with an annular protrusion and the both sides of annular protrusion is provided with installing hole, described ear muff connector bottom is provided with one and is nested in retainer ring on annular protrusion, the stopple corresponding with position of mounting hole is provided with inside described retainer ring, the middle part of described annular protrusion is provided with the through hole that is communicated to vacuum chamber, an extraction valve is adhesively fixed with in described through hole, a self-sealed rubber exhaust tube is bonded with in the middle part of extraction valve.
Improve as one, described Earcap supporter both sides are respectively provided with an intercalation groove, and described ear muff connector can front and back pull activity in intercalation groove.
As further improvement, described vacuum chamber inner housing oral area is provided with overlap, and described vacuum chamber inner housing is adhesively fixed by overlap and vacuum chamber housing body.
As further improvement, the outside of described overlap is adhesively fixed with a rubber seal.
(3) beneficial effect
This utility model, relative to prior art, has following beneficial effect:
Utility model provides a kind of vacuum sound insulation ear muff, at human body outside ear, a region of no pressure is manufactured around auricle, utilize the principle of vacuum not conduct acoustic waves, the sound wave propagated in air is blocked outside external auditory meatus, not only effective under low decibel environment, under superelevation decibel environment, still there is good soundproof effect, simultaneously, the vacuum area of ear muff is enough large, and the contact of parts discord external auditory meatus, so ear muff both can play the effect of noise elimination, can not feel bad because using for a long time again and even injure ear.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As Fig. 1, a kind of vacuum sound insulation ear muff shown in Fig. 2 and Fig. 3, comprise Earcap supporter 1, ear muff connector 2, vacuum chamber housing body 3 and vacuum chamber inner housing 4, described ear muff connector 2 is flexibly connected with Earcap supporter 1, described vacuum chamber housing body 3 and vacuum chamber inner housing 4 are nest shape and are adhesively fixed in the same way and form a vacuum chamber 5 between, described vacuum chamber housing body 3 arranged outside has an annular protrusion 31 and the both sides of annular protrusion 31 is provided with installing hole 32, described ear muff connector 2 bottom is provided with one and is nested in retainer ring 21 on annular protrusion 31, the stopple 22 corresponding with installing hole 32 position is provided with inside described retainer ring 21, the middle part of described annular protrusion 31 is provided with the through hole 33 that is communicated to vacuum chamber 5, an extraction valve 6 is adhesively fixed with in described through hole 33, a self-sealed rubber exhaust tube 7 is bonded with in the middle part of extraction valve 6.
Wherein, described Earcap supporter 1 both sides are respectively provided with an intercalation groove 11, described ear muff connector 2 can in intercalation groove 11 before and after pull movable, suitably can regulate the size of ear muff according to the size of different head; Described vacuum chamber inner housing 4 oral area is provided with overlap 41, and described vacuum chamber inner housing 4 is adhesively fixed by overlap 41 and vacuum chamber housing body 3; The outside of described overlap 41 is adhesively fixed with a rubber seal 8.
A kind of vacuum sound insulation ear muff that above specific embodiment is mentioned, according to assemble method, the physical build-up of ear muff is assembled, be configured on head by the same with common headphones for ear muff, suitably adjust ear muff simultaneously, rubber seal 8 is reached with skin and contacts preferably.With bleeding, pin inserts vacuum chamber 5 from self-sealed rubber exhaust tube 7, note, bleeding the external diameter of pin should be slightly larger than the internal diameter of self-sealed rubber exhaust tube 7, self-sealed rubber exhaust tube 7 should have suitable elasticity and surface viscosity, self-sealed rubber exhaust tube 7 can automatic-sealed better when extracting self-sealed rubber exhaust tube 7 for pin can to prevent air return and guarantee in pumping process from bleeding like this, prevents air return.After having bled, pin of bleeding is extracted with suitable speed, when pin of bleeding is about to and exhaust tube departs from, self-sealed rubber exhaust tube 7 is identical with vacuum chamber 5, air pressure inside is 0, and external pressure is an atmospheric pressure, and such atmospheric pressure can the inwall of self-sealed rubber exhaust tube 7 forcing together tightly, because tube wall has viscosity, realize the automatic-sealed of self-sealed rubber exhaust tube 7.After extracting pin of bleeding, by suitable method, secondary seal is carried out to extraction valve 6.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from this utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of this utility model request protection, all records in detail in the claims.
