Description

Simple nature fresh-air admitting-into-room device

Technical field

The utility model relates to a kind of nature fresh-air admitting-into-room device.

Background technology

The quality of indoor environment is more and more received people's attention, keeps good room air that the health of the person is played an important role.Yet growth in the living standard along with people, the finishing in house is superior day by day, ornament materials and furniture discharge a large amount of pernicious gases on the one hand, on the other hand, the structure seal of door and window is become better and better, and does not generally have ventilating mechanisms, and just necessary door and window if desired ventilates, very inconvenient, and frequent door and window.Cause room ventilation bad like this, indoor air quality seriously descends, and influences the healthy of inhabitation personnel.

Summary of the invention

The purpose of this utility model just provides a kind of simple nature fresh-air admitting-into-room device, to solve the problem of the room ventilation that prior art exists.

The technical solution of the utility model is: comprise ventilation duct, shutter and airstrainer, shutter is installed in the outer end of ventilation duct, and airstrainer is loaded on the interior cross section of ventilation duct.

Described airstrainer is attached to described shutter inboard.

Go back at least one airstrainer on the cross section in described ventilation duct.

Described airstrainer is a drawer-type structure, one or connect at interval and slide more than one airstrainer and insert in the described ventilation duct.

Described a plurality of airstrainer is by tubular housing, framework, and single connecting rod or multi-link bar are connected in series.

On the connecting rod between the described adjacent airstrainer, be with supporting sleeve.

Edge at the airstrainer of outermost end is provided with upholstery border.

Be provided with handle at the airstrainer of described outermost end or the outside of upholstery border.

The utility model passes house sidings with ventilation duct when using, its shutter is positioned at outdoor, has advantages such as simple in structure, easy for installation, good filtration effect, replacing screen pack convenience.

The specific embodiment

Referring to Fig. 1～Figure 15, basic structure of the present utility model comprises ventilation duct 1, shutter 2 and airstrainer 3, and shutter 2 is installed in the outer end of ventilation duct 1, and airstrainer 3 is loaded on the cross section in the ventilation duct 1.Also can handle (not shown) be set, with conveniently assemble and disassemble airstrainer 3 in an indoor side of the airstrainer 3 that is positioned at ventilation duct 1 the inner.

Fig. 1 is the vertical sectional structure of embodiment that the utlity model has the drawer type screen pack, and a plurality of airstrainers 3 are by tubular housing or framework 4 series connection at interval, and slip is inserted in the described ventilation duct 1.Also can be provided with upholstery border 5 (referring to Fig. 2) at the edge of the airstrainer 3 of low order end, the also promising airstrainer 3 of upholstery border 5 inserts the effect of location in the ventilation ducts 1.

Handle 6 also can be set in upholstery border 5 outsides.

Ventilation duct 1 of the present utility model can be rectangle (comprising square), circular or other shape, and airstrainer 3 and upholstery border 5 are corresponding shape (circle square and shown in Figure 6 as shown in Figure 3).

When the utility model is a plurality of airstrainer 3, can pass through tubular housing 4 (as shown in Figure 5), framework 4 (as shown in Figure 6), single connecting rod 7 (as Fig. 8, Fig. 9, shown in Figure 12) or multi-link bar 7 (Figure 10 and Figure 11) are connected in series.When adopting single connecting rod or multi-link bar 7 to be connected in series, can pass through housing (frame) 4 between the adjacent airstrainer 3 and support, perhaps adopt supporting sleeve shown in Figure 12 8 to support, to keep the distance between the airstrainer 3.The indoor end of connecting rod 7 can stretch out certain distance as handle.

Referring to Fig. 7, described airstrainer 3 also can be attached to described shutter 2 inboards.Other airstrainer also can be set in ventilation duct 1 in this case.

Screen pack of the present utility model also can directly be fixed in the ventilation duct 1 or in the single insertion ventilation duct 1.

The utility model also can be installed ventilation adjustment doors 10 in the inner of ventilation duct 1, and shown in Figure 14 is push-pull structure, and shown in Figure 15 is by pivotally connected swing door.Be provided with handle 12 in the outside of ventilation adjustment doors 10, be provided with bayonet lock 11 in the inboard.The structure of ventilation adjustment doors 10 is not limited to said structure, regulates ventilation such as the coincidence that can adopt double-deck rotary type gate open via hole and dislocation, and other structure that can regulate ventilation (area).

The utility model when using (referring to Figure 13) passes house sidings 9 with ventilation duct 1, and its shutter 2 is positioned at outdoor, has advantages such as simple in structure, easy for installation, good filtration effect, replacing screen pack convenience.
