The most clearly mark).Motor drives flabellum to extract air the row from ventilating fan 2 from the air inlet side of ventilating fan 2
Air is discharged by gas side.In FIG, ventilating fan 1 is from outdoor (air inlet side) extraction air, and is discharged by air
To indoor (exhaust side).
Ventilating fan 1 also includes multiple guide blades 3.According to the embodiment shown in Fig. 1-4, multiple guide blades 3 set
Put the exhaust side at ventilating fan 2, i.e. near indoor side.According to other embodiments, multiple guide blades 3 are also
The air inlet side of ventilating fan 2 can be arranged on.
Multiple guide blades 3 are pivotally disposed on blower housing 2.For example, it is possible at each guide blades 3
Two ends, are installed to guide blades 3 on blower housing 2 by pivoting device.Typically, multiple guide blades 3
It is located in parallel to one another.
According to the embodiment shown in Fig. 1-4, ventilating fan 1 also includes driving transposition 6, and driving means 6 can drive many
Individual guide blades 3 rotates.Multiple guide blades 3 can be by the driving of driving means 6 in closed position and opening
Rotate between position.When multiple guide blades 3 are in the closed position, multiple its places of guide blades 3 base closed
The cross section of the blower housing 2 of position so that air inlet side and the exhaust side of ventilating fan 1 separate substantially.So, when
When outside air temperature is the lowest or pollutes bigger, driving means 6 can drive multiple guide blades 3 to close stance
Put, with by ventilating fan 2 base closed.When multiple guide blades 3 are in deployed position, multiple guide blades 3
The most minimum to the resistance of air inlet, the air inflow of ventilating fan 2 is maximum.
According to preferred embodiment of the present utility model, by driving means 6, multiple guide blades 3 can be in closed position
And move between deployed position, and rest on the optional position between closed position and deployed position as required.When many
During the position that individual guide blades 3 is between deployed position and closed position, multiple guide blades 3 resistance to air inlet
Gradually changing, the air inflow of ventilating fan 2 gradually changes.By suitably controlling the position of multiple guide blades 3, can
Correspondingly to control the air inflow of ventilating fan 2.
According to an embodiment of the present utility model, ventilating fan 2 also includes being respectively connected with multiple guide blades 3
Attachment means 9, attachment means 9 is connected with driving means 6, thus drives multiple guide blades 3.Preferably, connect
Device 9 can be connecting rod, and connecting rod is connected with each in multiple guide blades 3.Such as, connecting rod is passed through
Privot mechanism is connected with the top of guide blades 3, such as with reference to Fig. 3, such that it is able to drive guide blades 3 to rotate and not
It can be interfered to rotate.
Attachment means 9 such as can be connected with driving means 6 by drag-line 4, thus by driving means 6 drive connection
Device 9, and then drive multiple guide blades 3.When attachment means 9 being connected with driving means 6 by drag-line 4,
Biasing device can be arranged be connected with attachment means, such as biasing spring 10.Biasing spring 10 can be with one end and connecting rod
Being connected, the other end is connected with blower housing 2.Alternatively, biasing spring 10 can with one end and multiple guide blades 3 it
One (preferably, the suitable guide blades at end position) is connected, and the other end is connected with blower housing 2.
In the embodiment of Fig. 1-4, biasing spring 10 such as can apply downward pulling force, by multiple guide blades 3
Pull to deployed position.When driving means 6 operates, it can apply pulling force upwards, thus by multiple guide blades 3
Drive towards closed position.The direction of such installation site and applying power is merely exemplary, if biasing spring
10 and driving means 6 can be fitted to each other, to drive multiple guide blades 3 to move between deployed position and closed position
Dynamic, and it is the most permissible to rest on optional position.Such as, biasing spring 10 can apply pulling force by multiple guide blades
3 towards closed position, and driving means 6 applies rightabout power and drives multiple guide blades 3 to deployed position.
In the embodiment shown in Fig. 1-4, driving means 6 includes motor and push-pull bar, and motor drives push-pull bar push-and-pull
Bar stretches out or retracts.Push-pull bar can be such as rackwork, changes, by rotating of motor, the length stretched out.Push away
Pull bar is connected to drag-line 4.Such as, push-pull bar is connected with drag-line 4 by pulley mechanism 8.Other connected modes are also can
Row.
In other embodiments, driving means 6 is connected with above-mentioned attachment means 9 by conducting wire rigid-connecting device, thus can
Directly to control the position of multiple guide blades 3, and without arranging biasing device.Such as, by adjusting orientation, will
Push-pull bar is directly connected with above-mentioned attachment means 9, thus is formed just between driving means 6 and above-mentioned attachment means 9
Property connect.So driving means 6 can directly control the position of multiple guide blades 3, and without arranging bias dress
Put.
According to preferred embodiment of the present utility model, when multiple guide blades 3 are arranged on the exhaust side of ventilating fan 1
Time, multiple guide blades 3 can guide discharge air-flow.Such as, the shape of multiple guide blades 3 is designed as arc
Shape, regulates the position of multiple guide blades 3 by driving means 6, preferably can guide discharging air-flow to required
Orientation.
According to preferred embodiment of the present utility model, when multiple guide blades 3 are arranged on the exhaust side of ventilating fan 1
Time, blower housing 2 can include the quadra 7 being arranged on exhaust side, and multiple guide blades 3 are arranged on quadra
On 7.
