In order to overcome the drawbacks of the prior art, referring to Figure 1 and Fig. 2, the ventilation with flapper of the utility model Device includes cabinet 10 and wind wheel 20；The two sides of the cabinet 10 are respectively arranged with main ventilation mouth 11 and side ventilation opening 12, institute It states main ventilation mouth 11 and side ventilation opening 12 is interconnected；The wind wheel 20 is rotatably arranged at the main ventilation mouth 11 of the cabinet； The ventilation device further includes 4 flappers 31,32,33,34；The flapper 31,32,33,34 is rotatably mounted On the bottom surface where the main ventilation mouth；Successively head and the tail splicing is trapped among the main ventilation mouth to 4 flappers 31,32,33,34 11 surroundings.

The main ventilation mouth 11 is located at the bottom surface of the cabinet 10, and the side ventilation opening 12 is located at the side of the cabinet 10 Face, the main ventilation mouth 11 are air inlet, and the side ventilation opening 12 is air outlet.

In one embodiment, the flapper 31,32,33,34 and being hinged at where the main ventilation mouth 11. Specifically, rotary sleeve a can be set in the side where the main ventilation mouth 11, and the rotary sleeve a is in prism-frustum-shaped, on lower width Narrow, centre is equipped with groove；The flapper includes shaft b, and the shaft b is placed in groove, and the rotary sleeve a covers residence State shaft b.Side where the main ventilation mouth 11 can also be connected with the flapper 31,32,33,34 by hinge It connects.

Further, the side where the main ventilation mouth 11 is provided with moving fastening 40, when the flapper 31, 32,33,34 when turning to the state for the side being close to where the main ventilation mouth 11, and the moving fastening 40 is withheld in the work Dynamic 31,32,33,34 side far from shaft of baffle, is not unfolded so that 31,32,33,34 folding of the flapper is got up, and fits For being mounted on traditional furred ceiling.

Preferably, the flapper 31,32,33,34 is rectangular slab.

In order to enable the flapper 31,32,33,34 that folding is got up occupies less space, ventilation device good integrity, with And the usage quantity of moving fastening 40 is reduced, the both ends of two opposite flappers 31,33 include recess；Another two is opposite The both ends of flapper 32,34 include projection, and recess and projection refer to that the centre of flapper and the baffle plate body at both ends do not exist Same plane, recess refer to the baffle plate body at both ends lower than intermediate baffle plate body, during projection refers to that the baffle plate body at both ends is higher than Between baffle plate body；The formation of recess and projection can be the difference in height that flapper is bent to form, and be also possible to centre and two The different formation difference in height of the baffle plate body thickness at end.Lead to when the flapper 31,32,33,34 turns to the abutting master When the state of the bottom surface where air port, the projection lid is located on recess namely the both ends of flapper 32,34 are pressing against active catch The both ends of plate 31,33 are played by the effect of the fixed flapper 31,33 of flapper 32,34.At this moment, the moving fastening 40 The flapper 32,34 including projection can be set and between main ventilation mouth only with two.

The utility model is also provided with multiple mounting holes 50 at four angles of the bottom surface where the main ventilation mouth.The peace It fills hole to be used to use screw and nut mounting fixing parts 60, the fixing piece 60 is for fixing the ventilation device of the utility model On roof keel.

The ventilation device with flapper of the utility model further includes chimney fan 70, and the chimney fan 70 is arranged in institute It states on the side ventilation opening 12 on cabinet.

Further, the chimney fan 70 is oval chimney fan, and the exit of the ellipse chimney fan is provided with a plurality of grid The rib 71 of trellis.

Fig. 3 and Fig. 4 are please referred to, is the usage state diagram of the ventilation device with flapper of the utility model.

When being installed on traditional furred ceiling, 31,32,33,34 folding of flapper is got up, two side pressures of flapper 32,34 The both ends of flapper 31,33, moving fastening 40 withhold flapper 32,34, thus flapper 31,32,33,34 formed One entirety not loose or dislocation.Main ventilation mouth 11 is slightly below ceiling gypsum board or wooden splint, can directly pacify outside main ventilation mouth 11 Wind outlet panel is filled, the flapper 31,32,33,34 that folding is got up does not influence the assembly and fixation of wind outlet panel.

When being installed on Integral ceiling, the expansion of flapper 31,32,33,34 is erected to form a frame-shaped construction, will be led Outside the roof keel of the wind guiding Integral ceiling of ventilation opening 11, it effectively prevent taking out the effect of interlayer wind, the work so that indoor environment is taken a breath Make efficiency maximization, at this time main ventilation mouth 11 plus flapper 31,32,33,34 height after it is concordant with roof keel, then will Wind outlet panel is installed to aluminum-pinch.The open angle of flapper 31,32,33,34 can according to need setting, so that this is practical The novel Integral ceiling installation keel level that can be adapted to different size, versatility are good.

Compared to the prior art, the ventilation device with flapper of the utility model passes through the rotatable activity of setting Flapper folding is got up to be mounted directly wind outlet panel by baffle when ventilation device is mounted on traditional furred ceiling；Work as ventilation device When being mounted on Integral ceiling, flapper standing is come, then wind outlet panel is installed, the wind of main ventilation mouth is exported into Integral ceiling Outside, it prevents from taking out interlayer wind；Biography is just common to which the ventilation device with flapper of the utility model may not need dismounting System furred ceiling and Integral ceiling, increase the scope of application.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.
