Description

A kind of air exchange case

The utility model relates to air exchanging apparatus, particularly a kind of sound insulation, dustproof air exchange case.

Existing air exchange equipment is more, and as the air-conditioning interchanger, it installs trouble, and expense is expensive, and another kind is mounted in indoor air cleaner, and it takes out, arranges filtration by crossing filter core to room air, for than a little less than its filtration of big room,

It is better that the purpose of this utility model provides a kind of soundproof effect, be not subjected to the fabricating yard restriction, guarantee the air exchange case that room air circulates.

The utility model comprises casing, is provided with air inlet and exhaust outlet, blower fan in the casing, is separated into two independently air intake Sound Attenuator and air draft Sound Attenuators in the casing, between two Sound Attenuators in the top or middle part of casing or the bottom be provided with the telescopic extension body; The ennation inwall has quieter material

Independently air draft Sound Attenuator and air intake Sound Attenuator are arranged in the above casing, and shape is changeed Wei rotation in its air channel, and the air channel inwall is coated with the noise reduction cotton; The air inlet of air intake Sound Attenuator is provided with blower fan; Be fixed with wind guiding louver on a casing and the indoor side of joining; Wind guiding louver is divided into the upper and lower, upper blade up, lower blade is down; The exhaust outlet end of the air inlet end of air intake Sound Attenuator and air opening end and air draft Sound Attenuator is equipped with filter screen; Air intake Sound Attenuator and the indoor wind passage mouth end that joins are provided with a cavity, and this cavity can be placed health medicine or freshener, and this cavity and Nei Dao and indoor being connected.

The utility model has adopted technique scheme, owing on the casing telescopic extension body is arranged, this ennation can make that casing is fastened on the window, on the door, be not subjected to the restriction of frame size, installs more convenient; Air inlet duct and exhausting duct are separate in the casing, do not disturb mutually, have kept wind speed, air channel Wei rotation shape road, and the noise reduction cotton is arranged in the air channel surface coverage, can reach soundproof effect effectively; The filter screen of the air inlet end of air intake Sound Attenuator and the filter screen of air opening end can completely cut off external sand and dust preferably, and the filter screen of air draft Sound Attenuator exhaust outlet end can stop effectively that then external winged insect enters the air channel; Wind guiding louver can make room air form a closed circuit, accelerate the exchange of room air, the cavity of the placement health medicine that the air outlet place of air intake Sound Attenuator is provided with is brought into the smell in the cavity indoor by the air intake of blower fan suction, make medicine be full of the room, play pure and fresh function of health care.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the cross-sectional view of another enforcement of the utility model;

Fig. 3 is the utility model cross-sectional view of implementing again;

Fig. 4 is that the utility model is installed in generalized section on the forms;

Fig. 5 is that the utility model is installed in the structural representation on the forms;

As shown in Figure 1: the utility model comprises casing 1, independently air intake Sound Attenuator 3 and air draft Sound Attenuator 2 are arranged in the casing 1, shape is changeed Wei rotation in air channel in the Sound Attenuator, and the air channel inwall is coated with the noise reduction cotton, play soundproof effect preferably, one ennation 4 is arranged between two Sound Attenuators, these ennation 4 inwalls are coated with the noise reduction cotton, and can be according to setting height(from bottom) free adjustment length, to make things convenient for the fixing of casing 1, a blower fan 7 is all fixed at the air inlet place of air intake Sound Attenuator 3 and the exhaust outlet place of air draft Sound Attenuator 2, and blower fan can be drawn into air or discharge rapidly, to accelerate the circulation of room air, be fixed with wind guiding louver 5 on a casing 1 and the indoor side that joins, this wind guiding louver 5 is divided into the upper and lower, and the wind blade on top makes wind direction up up, the wind blade of bottom down, the wind direction that is drawn into is discharged down, thereby, make room air and outdoor air reach the purpose of exchange at air circulation loop of indoor formation; The air inlet end and the air opening end of air intake Sound Attenuator 3 are equipped with filter screen 8 respectively, and in the outer sand and dust inlet chamber of air lock, the exhaust outlet end of air draft Sound Attenuator 2 also is equipped with filter screen 8 effectively, and this filter screen can stop that outdoor winged insect etc. is by in the inlet chamber of air channel; Air intake Sound Attenuator 3 is provided with a cavity 6 with the indoor wind passage mouth place that joins, this cavity 6 and air channel and indoor linking to each other, and when can place health medicine or freshener in cavity 6 after, the wind in the air channel is brought the smell in the cavity 6 into indoor, reaches health-care effect.

The operation principle of Fig. 2 is identical with Fig. 1, and described telescopic extension body 4 is fixed on the top of casing 1.

The operation principle of Fig. 3 is identical with Fig. 1, and described telescopic extension body 4 is fixed on the bottom of casing 1.

As Fig. 4, shown in Figure 5: the utility model is combined on the sash lock of double-deck sound insulation forms 10 by hasp 9 movable buttons of casing 1 side, and can make things convenient for installation or removal, ennation 4 is equipped with on the middle part of casing 1 and top respectively, ennation 4 inwalls are coated with the noise reduction cotton, the ennation 4 on top can be combined closely with forms 10, prevent entering of noise, the ennation 4 at casing 1 middle part can be according to the height free adjustment of forms 10, to be fit to the demand of different size; During use, open blower fan 7, wind is drawn into air intake Sound Attenuator 3, after filtering the duct attenuation of sand and dust, rotation commentaries on classics shape, filter 8 discharges from the bottom of wind guiding louver 5, if in cavity 6, placed freshener etc., it is indoor that the wind of discharging can be with pure and fresh fragrance to spill into, when room air constantly increases the formation negative pressure, air can enter air draft Sound Attenuator 2 from the air inlet on wind guiding louver 5 tops, and, so constantly back and forth, indoor air can be discharged by the exhaust outlet discharge, extract outdoor air, make indoor remain with fresh air, clean.
