Abstract

The utility model relates to a wind supplier blowing wind towards indoor and refining the air, being a negative wind supplying device for the central fresh air system, and is used for shifting the air indoor in the buildings. The utility model has a wave shape tube body, an end cover is arranged on both ends, an outside wall wind inlet is arranged on the outer end cover, an inner wall wind outlet is arranged on the inner end cover, cylinder sponge filter net and active charcoal filter net core are arranged inside the tube orderly from the outside end to the inside, an extendable outwards raining prevention hood is arranged at the outside end, and the wind outlet size of the inner wall end can be adjusted. When installing the wall wind supplier, the wave shape tube body is through the wall, the outdoor air enters the tube and the dust is filtered out by the sponge filter net, the harmful parts inside the air is absorbed and expelled by the active charcoal filter net, and the air indoor is kept fresh and clean.

Description

Wall air intaker

Technical field

The utility model relates to a kind of to indoor air inlet and the wall air intaker that makes it to purify, is the part of central VMC.

Background technology

Because a large amount of harmful substances that upholster and daily life produce can cause health hazard, therefore must make room air obtain upgrading.On the other hand, along with the quickening of rapid economy development and urbanization process, the air pollution in city is on the rise, and can not guarantee air quality with the way of the ventilation of windowing.From the indoor environment laws and regulations of present domestic promulgation and the importance of " IAQ standard " visible interior air.Therefore, improving IAQ is just to become a kind of tangible demand, the new wind of central authorities is exactly the air exchange system that meets this demand, it is made up of central aspirator and indoor air-intaker, extract each indoor foul atmosphere of building under the system by central aspirator, while to the new wind of indoor feeding, reaches the purpose of indoor air-changing by air-intaker.At present, this central VMC in some hotel, commercial and residential building and some novel buildings be used.But, the air-intaker of existing VMC mostly is and is installed in the flat of door and window top, can only enter from the door and window top, and be plate, be unfavorable for installing, and sealing is relatively poor, easily loosening, be unfavorable for intercepting rainwater and pollutant, easily stop up, the filter effect of filter core is not remarkable yet, and the inner room air-out is also inhomogeneous.

Summary of the invention

The purpose of this utility model provides a kind of wall air intaker that body of wall is installed that is suitable for, and overcomes the shortcoming of existing flat formula air-intaker, and is easy for installation and clean-up effect is remarkable.

This wall air intaker has a body, and the two ends of body are provided with end cap, and wherein outer end cap is provided with the exterior wall air inlet, and inner end cap is provided with the interior wall air outlet, and sponge screen pack and activated charcoal strainer are housed to the inner successively from the outer end in the pipe.

Said tube wall is corrugated.

Said exterior wall air inlet is grid-like, and the inboard of exterior wall air inlet is provided with dust screen.

Said outer end cap contains outwardly directed rain cover, and the downside of rain cover or while are provided with air intlet at side.

Said inner end cap by holder and can regulate the air port size valve form.

Said sponge screen pack and activated charcoal strainer are the cylindrical filter cores that contains cellular aperture.

One end of said activated charcoal strainer is compounded with pore sponge screen pack, and the two forms composite filter element.

The utility model wall air intaker is used for being furnished with the passive air intake of building such as apartment, villa, the commercial affairs building, hotel of the new blower fan of way flow.When installation is put, with the waveform body through body of wall, outdoor air enters in the pipe through sponge screen pack elimination dust, with removing harmful components in the air after activated charcoal strainer is adsorbed, for example multiple organic gas and foul gas etc., purify air to indoor input by air outlet at last, protect indoor fresh air.This device air flows unobstructed, and ventilation effect is good; It is little to take up room, noiselessness; Air inlet can be prevented rainwater and dirt; Adopt the PVC bellows reliably to be connected with body of wall.

Description of drawings

Fig. 1 is the structural representation of wall air intaker.

Fig. 2 and Fig. 3 be respectively the B of Fig. 1 to view and A to view.

Among the figure, 1-inner end cap, 1-1-end cap valve handle, 1-2-air outlet, 2-activated charcoal strainer, 3-bellows, 4-sponge screen pack, 5-outer end cap, 5-1-dust screen, 5-2-grating type air inlet, 5-3-rain cover, 5-31-rain cover air intlet.

The specific embodiment

Shown in Fig. 1 embodiment, the right-hand member of bellows 3 is the wall outside, is provided with outer end cap 5, and left end is side within the walls, is provided with inner end cap 1.Outer end cap 5 is provided with grating type air inlet 5-2, and the inboard of air inlet is fixed with dust screen 5-1, and individual side is provided with rain cover 5-3, in the rain cover, the bottom has air intlet 5-31.Two sponge screen packs 4 and an activated charcoal strainer 2 are housed in the bellows, and each screen pack is even makes columniform filter core, and is provided with multiple aperture specification, can be according to bellows length and definite filter core quantity and the aperture specification of using of outdoor air quality.

Selected two sponge screen pack filter cores 4 in this example for use, wherein the sponge screen pack aperture specification selected for use of front side (by inlet side) is greater than rear side; Activated charcoal strainer filter core 2 is composite filter elements, and promptly first half is an activated charcoal strainer, the latter half of littler sponge screen pack in sector hole footpath, the tiny dirt particle of elimination of being compounded with.

In this example, outer end cap 5 fuses with dust screen 5-1, grating type air inlet 5-2 and rain cover 5-3, and rain cover 5-3 can avoid rainwater to pour into indoor along air inlet.Dust screen 5-1 stops big dust and solid impurity.Inner end cap 1 is made up of holder and the valve that can regulate the air port size, can change the size of air outlet among the figure by handle 1-1 governor valve aperture.
