The specific embodiment
A kind of noise reduction dust removal by ventilation glass that the utility model provides, utilize noise-cancelling theory to eliminate the noise, wherein, noise-cancelling theory comprises: the noise elimination of expanding, sound wave interference are eliminated the noise, reflection is eliminated the noise etc., described expansion noise-cancelling theory is that two silencing cavity of design are big more many than air intake, eliminates the noise by twice expansion; Described sound wave interference noise-cancelling theory is a sound wave when passing through two noise elimination cavities, is subjected to resident sound wave interference in the chamber and eliminates the noise; Described reflection noise-cancelling theory is by design two-layer at least retaining wall (also being sound-proof wall), reflects noise reduction.
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below the utility model is described in further details with reference to the accompanying drawing embodiment that develops simultaneously.
A kind of noise reduction dust removal by ventilation glass that the utility model embodiment is provided, its outward appearance as shown in Figure 1, comprise glass outer 210 and inner layer glass 220 that mutual applying is set together, as shown in Figure 3, between described glass outer 210 and inner layer glass 220, be combined to form several anechoic chambers 100 by depression.Certainly, described glass outer and inner layer glass can one-body moldedly be an integral body also.Utilize and expand, interfere, reflect noise-cancelling theory, each described anechoic chamber 100 setting is formed by connecting by the logical silencing cavity 110 and 120 of upper and lower two gas phases, like this, the sound that enters anechoic chamber 100 can be eliminated the noise by twice expansion through the logical silencing cavity 110 and 120 of upper and lower two gas phases.Wherein, the shape of described silencing cavity can be set to multiple shape, as circle, ellipse or circular arc, can certainly be other irregular shapes such as square, palm shaped, cosmos, shell-like.This enforcement is the circle that is made as of described upper and lower silencing cavity 110 and 120, and internal diameter is made as 1-2cm.
Further, described upper and lower two silencing cavity 110 and 120 are connected merging in the position less than its internal diameter and form first sound-proof wall 131, as shown in Figures 2 and 3, the design of described first sound-proof wall is to utilize the reflection noise-cancelling theory, described noise can be reflected noise elimination; And first gravity vent 121 is arranged in the bottom arranged outside of described down silencing cavity 120, be used for communicating with outdoor air; Silencing cavity 110 is provided with second gravity vent 122 on described, is used for communicating with the indoor air.Wherein, described first gravity vent 121, second gravity vent 122 and upper and lower silencing cavity connecting hole 130 not on same axis, are convenient to carry out sound wave interference noise elimination and reflection and are eliminated the noise; As shown in Figure 2, and the interior diameter of described first gravity vent 121 and second gravity vent 122 is set to 0.2-0.4cm, can play ventilation, dedusting and mosquito-proof function.In addition,, generally first gravity vent of air intake is made as little more a lot, silencing cavity preferably is set is the integral multiple of gravity vent internal diameter separately preferably, help expanding, interfering noise elimination more than described silencing cavity internal diameter according to the expansion noise-cancelling theory.
Further, as shown in Figure 3, described second gravity vent, 122 inside walls protrude in silencing cavity 110 inwalls and establish, and form second sound-proof wall 132 in the position relative with described first sound-proof wall 131.Substantially can reach noise requirement by first sound- proof wall 131 and 132 liang of secondary reflections noise eliminations of second sound-proof wall.
Operating principle of the present utility model, as shown in Figure 3, when the noise and the air of outside are come in from first gravity vent 121, eliminate the noise through first sound- proof wall 131 and 132 liang of secondary reflections of second sound-proof wall, eliminate the noise in conjunction with expansion, the sound wave interference of two silencing cavity 110 and 120 again and can eliminate outdoor noise substantially, and the air of the anechoic chamber 100 that flows through was by two silencing cavity 110 and 120 o'clock, flow velocity slows down, dust in air is deposited in down the bottom of silencing cavity 120, and the new air after filtering flows into by second gravity vent 122 indoor.So glass of the present utility model can not only reach the requirement of sound insulation and noise reduction, and have good ventilation effect, can guarantee indoor, outdoor circulation of air, and have dedusting function.
And noise reduction dust removal by ventilation glass of the present utility model, also very convenient when cleaning, only need at chamber side direction second gravity vent 122 water sprays, just the dust that is deposited in down silencing cavity 120 bottoms can be cleared out by first gravity vent 121, to reach the purpose of cleaning, so noise reduction dust removal by ventilation glass of the present utility model is very practical, be preferably described first gravity vent 121 is connected with the lower edge of following silencing cavity 120, be convenient to the dedusting cleaning.
The utility model provides a kind of noise reduction dust removal by ventilation glass, owing to adopt it to comprise glass outer and inner layer glass that mutual applying is provided with, between described glass outer and the inner layer glass, be combined to form several anechoic chambers by depression, each described anechoic chamber comprises last silencing cavity and the following silencing cavity that two gas phases are logical, and the described silencing cavity that goes up is connected merging formation first sound-proof wall with following silencing cavity in the position less than its internal diameter; In the described bottom arranged outside of silencing cavity down first gravity vent is arranged, be used for communicating with outdoor air; Silencing cavity is provided with second gravity vent on described, is used for communicating with the indoor air; The described second gravity vent inside wall protrudes in the silencing cavity inwall and establishes, and forms second sound-proof wall in the position relative with described first sound-proof wall; It can not only reach the requirement of sound insulation and noise reduction, and has good ventilation effect, can guarantee indoor, outdoor circulation of air, and has dedusting, mosquito-proof function.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
