Air strainers are arranged in length direction inside the ventilation hose. Vent holes are reserved in corresponding area on the internal cover divided by strainers as well as the corresponding area on the other area divided by the strainers. In application, the ventilation hose of the utility model shall drill through building walls, after which the internal and external covers shall be positioned. The utility model has the advantages of simple structure, convenient installation, large strainer effective area and convenient strainer replacement, etc.
Description
Technical field
The utility model relates to a kind of fresh-air entering-room exchanging device, is mainly used in the gravity-flow ventilation of indoor and outdoor.
Background technology
The quality of indoor environment more and more is subject to people's attention, and 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 fresh-air entering-room exchanging device, to solve the problem of the room ventilation that prior art exists.
The technical solution of the utility model is: comprise ventilation duct and the inner cap and the enclosing cover that are connected its two ends, in described ventilation duct, be provided with the airstrainer that is provided with along its length direction, leave ventilating opening at described inner cap corresponding to being filtered the part that net cuts apart, also leave ventilating opening corresponding to being filtered another part that net cuts apart at described enclosing cover.
Be provided with relative screen pack guide rail in the middle of the top and bottom of described ventilation duct inboard or two sides, insert in this guide rail on the both sides of described airstrainer.
Half of described enclosing cover is described ventilating opening, and this ventilating opening is a louver structure.
Half of described inner cap is described ventilating opening, and described screen pack guide rail is exposed in this ventilating opening, is provided with in this ventilating opening in the transverse slipway in sliding door and the slip insertion ventilating opening.
Adopt screw, grafting, clamping or bonded structure to be connected between described ventilation duct and inner cap and the enclosing cover.
The utility model passes house sidings with ventilation duct when using, exterior and interior cover is installed again, has simple in structurely, easy for installation, and the screen pack effective area is big, changes advantages such as screen pack is convenient.
