Pipeline regulating valve 111 is provided with wind branch pipe 11, the air draught which is passed through house unit for adjusting is big
It is small.Bearing 5 by rod piece weld holder in ventilation duct 1 (such as Fig. 2).1 top open part of ventilation duct stretches into shaft 3, and shaft 3 is installed
On several bearings 5 in ventilation duct 1,3 axis rotate shaft 3 around the shaft.In order to obtain more stable connection effect, shaft
3 two bearings 5 being installed in ventilation duct 1 are rotatably connected.
3 inserting end of shaft is fixedly connected with the fan leaf 4, the fan leaf 4 rotated with shaft 3 and be ventilation duct 1 blow or
Exhausting.Shaft 3 stretches out end side surface and is fixedly connected described by aerofoil 2, is connected to shaft 3 by rod piece by aerofoil 2 and stretches out end side surface,
It is parallel with 3 axis of shaft (such as Fig. 2) by 2 plane of aerofoil；Preferably, it is axis with shaft 3 by aerofoil 2, uniform circular is provided with
3-6 pieces.
At 11 port of branch vent connect air cleaning unit 13, air cleaning unit 13 include the first filtration 131,
Second filtration 132 and ultraviolet generater 133 (such as Fig. 3).
First filtration 131 includes first chamber 1311 and second chamber 1312, first chamber 1311 and second chamber
1312 lower parts connect to form connected region, which is used to store a little liquid-state filter medium, such as fluid or clear
Water.First chamber 1311 or 1312 side of second chamber are equipped with blow-off pipe 1313, which is used to discharge, replace connection
Liquid-state filter medium in region, is provided with switch valve on blow-off pipe 1313.In the present embodiment, the connected region bottom is deposited
Put clear water.Preferably, first filtration 131 makes of transparent material, and people, which can with the naked eye see, is stored in connection
Liquid-state filter medium in region.
Second filtration 132 includes filter chamber 1321 and filter layer 1322；Filter layer 1322 is by solid-state mistake by mesh sheet
Filter medium is packaged into flat and forms, and the filter layer 1322 of flat is placed in filter chamber 1321 and is divided into filter chamber 1321
Two chambers, further, filter chamber 1321 are equipped with switch gate, and filter layer 1322 can be easily replaced by switch gate.At this
In embodiment, solid-state filter medium is activated carbon.
Ultraviolet generater 133 includes generator chamber 1331 and quartz burner 1332；Quartz burner 1332 is placed in
In generator chamber 1331, and to output ultraviolet.
11 port of branch vent connects the top of first chamber 1311 of the first filtration 131, second chamber top 1312
Draw the one chamber in the filter chamber 1321 of a connecting tube and the second filtration 132 of connection, another chamber of filter chamber 1321
Draw another connecting tube and connect the generator chamber 1331 of ultraviolet generater 133, the opposite side of generator chamber 1331 in room
Draw a pipeline and be used to access house unit space air in face.7 headspace air-flows are built successively via ventilation duct 1, ventilation branch
Pipe 11, the first filtration 131, the second filtration 132 and ultraviolet generater 133, finally with building the house list in 7
The air draught of member swaps circulation.First filtration 131 is to the dust particles in air filtering excessively, the second filtration
132 to the fine grained or odour in adsorption filtration air, and ultraviolet generater 133 is to air progress sterilizing.
In order to avoid exterior debris enters house unit from ventilation duct 1, set in 1 opening of ventilation duct of construction ceiling
There is the conical filter cover 6 that filtering surface is convex, the opening of ventilation duct 1 is threadedly coupled with conical filter cover 6.
If the pipeline regulating valve 111 of branch vent 11 is all in closed mode, the strong wind by aerofoil 2 by building top
Blow so that 1 air pressure inside pressure of ventilation duct increases, and is difficult to 3 rotation around the shaft by aerofoil 2, so as to cause by aerofoil 2 by big wind
It is bad.It is against damages by aerofoil 2 in order to protect, in ventilation duct 1 part connection one protection branch pipe 12 of the fan leaf below 4；The protection
Branch pipe 12 includes big pipe fitting 121, small pipe fitting 122, valve ball 123 and elastic component 124 (such as Fig. 4).Big pipe fitting 121 and small pipe fitting 122
Smooth connection, big 121 internal diameter of pipe fitting is bigger than 123 diameter of valve ball, and 123 diameter of valve ball is bigger than 124 internal diameter of small pipe fitting, and valve ball 123 exists
Activity in big pipe fitting 121, and it is stuck in the junction of big pipe fitting 121 and small pipe fitting 122.124 one end of elastic component is fixed on small pipe fitting
In 122, the other end is fixed on 123 surface of valve ball, and valve ball 123 is held by elastic component 124, and 123 ball face sealing of valve ball blocks tubule
122 mouth of pipe of part.In the present embodiment, the elastic component 124 is spring.
The opening of small pipe fitting 122 in protection branch pipe 12 is connected with ventilation duct 1, the big opening of pipe fitting 121 and 7 extraneous airs of building
Airflow connection.In use, the inside of ventilation duct 1 is more than elastic component 124 with the draught head outside building 7 to the thrust of valve ball 123
During to the pulling force of valve ball 123, valve ball 123 is promoted, and the air-flow in ventilation duct 1 is flowed out from the protection branch pipe 12, inside ventilation duct 1
Air pressure is lowered.The protection branch pipe 12 has antihypertensive effect to ventilation duct 1；When protecting in branch pipe 12 elastic component 124 to valve ball 123
Pulling force when being more than in ventilation duct 1 with 7 external pressure differences of building to the active force of valve ball 123, ball valve 123 is held, ball valve 123
The small pipe fitting 122 in protection branch pipe 12 is blocked again.
Further, when 1 air pressure inside too little pressure of ventilation duct, be difficult to 3 rotation around the shaft by aerofoil 2, thus cause by
Aerofoil 2 is bad by big wind.It is against damages by aerofoil 2 in order to protect, connect another guarantor in ventilation duct 1 part of the fan leaf below 4
Branch pipe 12 is protected, the opening of big pipe fitting 121 in the protection branch pipe 12 is connected with ventilation duct 1, and the opening of small pipe fitting 122 is with building outside 7
Air draught connects.
