One end of air piping 1 spirally extends to the other end of ventilation shaft 1.The helicoidal structure of filter 2 of the invention is similar
In the double-spiral structure of DNA, filter 2 spirally extends to ventilation from one end of ventilation shaft 1 along the axis of ventilation shaft 1
The other end of pipeline 1, increases filter area;According to the relational expression between air quantity (Q), wind speed (V) and area (A): Q=VA,
Under identical air quantity, wind speed (V) and area (A) are inverse relation, and the area of filter is bigger, when air-flow passes through filter
Speed is smaller;Under identical air quantity, filter 2 of the invention increases filter area by helicoidal structure, to reduce
Air-flow passes through speed when filter 2, and then reduces filter 2 resistance, reduces filter 2 and damages, extends making for filter 2
Use the service life.
In addition, there are guide functions to air-flow since filter 2 is helicoidal structure, so that passing through the gas of filter 2
Flow distribution is uniform;There are delay losses (when fluid motion, due to itself stickiness and tracheid shape properties in ventilation shaft 1 for air-flow
Influence frictional force, this friction that fluid motion is hampered along process will be generated between fluid and wall surface and between fluid particle
Power is known as on-way resistance;Moving fluid overcomes on-way resistance and the energy loss that generates, referred to as linear loss), help to reduce
Air-flow passes through the filtering velocity of filter 2, reduces 2 resistance of filter, reduces the drag losses of filter 2, so as to reduce operation
Cost.Further, pass through the filtering velocity of filter 2 due to reducing air-flow, moreover it is possible to reduce noise.

The circular cross-section of air piping 1.Air-flow enters ventilation shaft 1 from air intake surface 3, after the filtering of filter 2, is discharged from outlet air surface 5;
For air-flow when passing through air intake surface 3, air inlet baffle 4 has barrier effect to air-flow, and there are local losses for air-flow, can reduce
The speed of air-flow, to reduce by 2 resistance of filter when by filter 2.
Preferably, the inner space of ventilation shaft 1 is separated into air inlet runner 7 and outlet air runner 8, air intake by filter 2
Road 7 is connected to air intake surface 3, and outlet air runner 8 is connected to outlet air surface 5.Since filter 2 is helicoidal structure, enters the wind runner 7 and go out
Distinguished and admirable road 8 is eddy channel, has guide functions to air-flow, so that air-flow also reduces filter uniformly across filter 2
2 resistances.
As the preferred embodiment of the present invention, baffle 4,6 semicircular in shape of air outlet guard board are entered the wind, air intake surface 3, outlet air surface 5 are in
Swivel pin 9 is respectively equipped on semicircle, air inlet baffle 4 and air outlet guard board 6, air inlet baffle 4 can be rotating around right with air outlet guard board 6
The rotation of swivel pin 9 or overturning answered, can by air intake surface 3 and air inlet 4 location swap of baffle, by outlet air surface 5 and air outlet guard board 6
Set exchange;;Further, the both ends of filter 2 respectively correspond at the diameter of air inlet baffle 4 and air outlet guard board 6, air inlet baffle 4,
Air outlet guard board 6 is played a supporting role at the both ends of filter 2, is reduced filter 2 and is deformed.In a preferred embodiment of the invention,
Swivel pin 9 is respectively arranged on the center point of air inlet baffle 4, air outlet guard board 6, and still, the present invention is not limited thereto, of the invention
In other embodiments, swivel pin 9 be can be set at other positions of air inlet baffle 4, air outlet guard board 6, as long as the setting of swivel pin 9
It can be realized air intake surface 3 and air inlet 4 location swap of baffle, by the function of outlet air surface 5 and 6 location swap of air outlet guard board.When
When deposited enough dust granules on filter 2 and being cleaned, baffle 4 need to will be only entered the wind around corresponding hinged
Pin 9 turns to the position of air intake surface 3, air outlet guard board 6 is turned to the position of outlet air surface 5 around corresponding swivel pin 9, i.e., will
Air intake surface 3 exchanges with air inlet baffle 4, exchanges outlet air surface 5 and air outlet guard board 6, can to the filter 2 in ventilation shaft 1 into
