A kind of ventilator

Technical field

The utility model relates to a kind of ventilation unit of house, specifically is a kind of ventilator.

Background technology

Existing ventilation unit is equipped with weather-proof device in the outer end of ventilation duct, and its shortcoming is the complex structure that has, and the weather-proof poor effect that has also influences attractive in appearance.

Summary of the invention

The purpose of this utility model just provides a kind of ventilator, solving that prior art exists or complex structure, or weather-proof poor effect, influence problem attractive in appearance.

The technical solution of the utility model is: comprise ventilation duct, blinds and wind and rain cover, blinds is loaded on the outer end of ventilation duct, in the outside of blinds the wind and rain cover is installed, and the top of this wind and rain cover and both sides are provided with the retaining edge of arc.

Described blinds comprises frame, louvre blade and plug-in connection, and louvre blade is located in the frame, and an end of this frame inserts the outer end of described ventilation duct, is respectively equipped with the plug-in connection that mutual correspondence is coincide in the outer end of this frame and the corresponding end of wind and rain cover.

Described plug-in connection comprises projection and the jack that coincide mutually.

Be provided with concavo-convex detent mechanism at the outer peripheral face of described blinds frame and the adjacent surface of ventilation duct.

Described concavo-convex detent mechanism is located at bottom, is made of axial fin that is located at the ventilation duct inboard and the groove that is located at blinds frame outer peripheral face, is provided with rhone or hole at the center of this fin; Ring flange at described blinds frame is provided with osculum corresponding to described groove.

The utility model has the advantages that: be provided with blinds and the dual protector of wind and rain cover, strengthened weather-proof effect; Whole device is pegged graft by three parts and combined, and is simple in structure, easy to assembly; Profile is streamlined, is not easy retain dust, and is elegant in appearance.

The specific embodiment

Referring to Fig. 1～Fig. 8, the utility model comprises ventilation duct 1, blinds 3 and wind and rain cover 2, and blinds 3 is loaded on the outer end (being positioned at an outdoor end during use) of ventilation duct 1, in the outside of blinds 3 wind and rain cover 2 is installed.

Described blinds 3 comprises flange form frame 33, louvre blade 31 and as the jack 32 of plug-in connection, louvre blade 31 is located in the frame 33, and both are integrative-structures.One end of this frame 33 inserts the outer end of described ventilation duct 1, is provided with several jacks that is uniformly distributed along the circumference 32 in the outer end of this frame 33 (ring flange), referring to Fig. 3～Fig. 5.

Described wind and rain cover 2 is made of along 21 annulus limit 22 and the retaining that is located at the arc on its top and both sides, is provided with projection 24 in the inboard on annulus limit 22, the jack 32 mutual corresponding grafting of projection 24 and blinds frame 33 corresponding sides.Be provided with the stile 23 that extends to blinds 3 one sides in the outer on annulus limit 22, be used to be enclosed in the outer of the flange form frame 33 of blinds, sealed the seam between blinds 3 and the wind and rain cover 2, prevent that rainwater from entering inside.

Also can be provided with concavo-convex

detent mechanism

34 and 11 at a place of the adjacent surface of the outer peripheral face of described blinds frame 33 and ventilation duct 1.The concavo-convex detent mechanism 34 of the foregoing description and 11 can be located at any position along circumference, and shape is not limit.

Referring to Fig. 9～Figure 13, this embodiment is the different of described concavo-convex detent mechanism with the difference of a last embodiment, and other structure is identical.Described concavo-convex detent mechanism is located at bottom, is made of axial fin 11 that is located at ventilation duct 1 inboard and the groove 34 that is located at blinds frame 33 outer peripheral faces, is provided with rhone or hole 12 at the center of this fin 11; Ring flange at described blinds frame is provided with osculum 35 corresponding to described groove 34 places.Rhone or hole 12 are corresponding with osculum 35, are used to discharge water in the ventilation duct 1 (rainwater that is blown into as condensed water or driving rain weather).
