Such as Chinese patent literature CN1176368 " air flow controller of air conditioner and controlling method thereof ", a kind of air flow controller of air conditioner is disclosed, it comes whole room is carried out air conditioning by control airflow direction and predetermined temperature, this device comprises the operation device, and it is used for providing air-supply by the zone that operated key carries out air conditioning to selected need; Control gear, it is used for airflow direction, flow and the predetermined temperature of control exhaust, to respond selected key to this zone air-supply; Be used for regulating the device of exhaust airstream direction, this device response control apparatus is with the angle of control blade; And compressor drive apparatus, it is used for the temperature-driven compressor predetermined according to control gear, to regulate room temperature.This device can only be regulated the direction through gas between two adjacent fan blades equally, can't control accurately the flow of gas.
Summary of the invention
The objective of the invention is prior art is improved, a kind of gas flow control device is provided, can control accurately the flow of gas, the technological scheme of employing is as follows:
A kind of gas flow control device of the present invention, comprise air door, the fan blade controlling mechanism, at least two fan blades, the two ends of described fan blade are equipped with rotating shaft, the rotating shaft at fan blade two ends is rotating being fixed on the air door respectively, it is characterized in that: described fan blade controlling mechanism comprises fan blade adjusting driving mechanism and at least two driving gears, the number of driving gear is identical with the number of fan blade, each driving gear is installed in the rotating shaft of corresponding fan blade the same side, the driving gear of adjacent fan blade is intermeshing, and fan blade is regulated the driving gear of a fan blade of output terminal connection of driving mechanism.Driving gear is intermeshing in the rotating shaft of two adjacent fan blade the same sides, so two adjacent fan blades, a fan blade clockwise rotates an angle, another then rotates counterclockwise an angle, the variation of gas flow is linear between two adjacent fan blades, and the direction of gas can not change, and therefore can control accurately gas flow.
For can more accurate adjusting through the flow of the gas between two adjacent fan blades, above-mentioned each driving gear is all identical, that is to say that the physical dimensions such as the number of teeth of each driving gear are all identical.Like this, two adjacent fan blades, a fan blade clockwise rotates an angle, and another then rotates counterclockwise an identical angle, the angular dimension that each fan blade rotates is the same, so can calculate accurately the flow through the gas between two adjacent fan blades.
A kind of scheme, the output terminal that described fan blade is regulated driving mechanism is output gear, the driving gear engagement of output gear and a fan blade.
The end that another kind of scheme, fan blade are provided with the rotating shaft of driving gear is provided with middle shaftgear, and the output terminal that fan blade is regulated driving mechanism is output gear, and output gear meshes with middle shaftgear.
A kind of scheme, it is actuating motor that described fan blade is regulated driving mechanism.
Another kind of scheme, it is double-action pinion and-rack pneumatic actuator that described fan blade is regulated driving mechanism.
A kind of more excellent scheme, the number of described fan blade are even number.
In order to limit the angular range of fan blade rotation, the driving gear of a described fan blade is provided with collision block, and air door is provided with the adjustable limit piece corresponding with collision block.
In time understand the angle that fan blade rotates for the ease of the user, the driving gear of a described fan blade is provided with pointer, and air door is provided with dial, and the pointer end is positioned at the dial top.
The present invention's beneficial effect against existing technologies is owing to be provided with the fan blade controlling mechanism, therefore can regulate accurately the flow through gas between two adjacent fan blades; Collision block, adjustable limit piece can limit the angular range that fan blade rotates; And pointer, dial can allow the user in time understand the angle that fan blade rotates.
