The downward magnet warehouse first of end opening, magnet warehouse first is interior to be equipped with columnar magnet first, which is equipped with upper friction
Pan Jia is equipped with fan blade in the shaft between magnet warehouse first and linear bearing；The lower part of magnet warehouse first be equipped with opening to
On magnet warehouse second, magnet warehouse second is internally provided with columnar magnet second, and magnet warehouse second is connected to air hose body by supporting rack
Inside；Columnar magnet first lower end is identical as the pole orientation of columnar magnet second upper end；The upper end of magnet warehouse second is equipped with friction
Disk second.
Preferably, the lower end of the columnar magnet second is connected with adjusting screw rod, which is mounted on magnet warehouse
On the lower face of second.
Preferably, the lower end of the vertical air hose body is additionally provided with lateral level and enters the room tube body, which enters the market pipe
Body is inserted into indoor part and is equipped with flow control valve and inlet non return check valve；
Preferably, the flow control valve includes entering the room matched outer barrel and disc-type baffle plate between tube body with level,
The nut that center in outer barrel is equipped with, the nut circumference are connected and fixed by the inner wall of supporting leg and outer barrel, the circle
The center of dish baffle is extended with adjusting screw rod, which is screwed into the nut.
Preferably, the inlet non return check valve includes the valve of the lid and flexible material that are covered in outside locking flow control valve
The middle part of limb, the lid is grid screen, and the upper edge of valve flap is fixed on the upper edge of the inside of lid.
The technique effect of the utility model
1. this is unpowered, the controllable magnetic of rotating speed floats ventilation device, using the floating structure of linear bearing and magnetic, significantly drops
The rotary resistance of fan blade and unpowered blast cap when low low speed natural exhaust；
2. when external wind pressure super large, unpowered blast cap will produce the rotation of bigger, and rotating in same direction for fan blade also carries at this time
Speed will produce downward thrust in such shaft and the frictional disk first in shaft driven to rub with following frictional disk second, shape
At the resistance of shaft, it is thus avoided that the rotation at full speed of shaft, to avoid the damage of component.
