Abstract
The utility model provides a draught fan air door device of an itinerant blowing and adsorbing cleaning machine, which comprises an air door, an air door seat, an air door shaft and a matching block, wherein a strong magnet is arranged in the matching block, which is welded on the air door, and is screwed on the draught fan casing with the air door seat and the air door shaft through a screw. Magnetic force of the magnet leads the air door to be restored and closed after the air door is opened and after utilizing the weight of the matching block to lead the air door to sag a certain angle, the operation is portable, and the restoring of the air door is fast.
Description
Technical field
The utility model relates to a kind of air door of fan, the automatically reset air door of fan device on especially a kind of touring pressure-vaccum cleaning machine that is used on the Weaving device.
Background technique
The spring that all is to use of the throttle structure that on touring pressure-vaccum cleaning machine, uses in the market, reset after utilizing the elasticity of spring to open, the common drawback of its existence is: a. because of touring cleaning machine operate as 24 hours do not shut down running, the unlatching of air door is frequent, opened once in average per 4 minutes, and split so the fatigue strength of spring is short easily inadequately; B. because is inhaling on the cotton passage mounting point of spring, and be difficult to cleaning, wounded easily; C. maintenance cost height.
The model utility content
The utility model provides a kind of air door of fan device of touring pressure-vaccum cleaning machine.
For solving above technical problem, a kind of air door of fan device of touring pressure-vaccum cleaning machine, be fixed into one by air door by axle of the air door and the activity of air door seat after, be fastened on the Blower Housing by screw, its innovative point is: also comprise counter weight device on the described air door.
Described counter weight device is the fixing balancing weight of hollow shape on air door, and the built-in strong magnet of empty therein part.
Described balancing weight can also can connect with machinery type for welding.
Described balancing weight device can be fixed weight piece on air door.
Described balancing weight device can be on air door fixing strong magnet.
The balancing weight of described built-in strong magnet or balancing weight or strong magnet are fixed on the end of air door away from the air door seat.
Described balancing weight can be arbitrary shape.
Described strong magnet can be arbitrary shape.
The advantage of above structure is: this device adopts the balancing weight fix built-in strong magnet on air door, behind door opening, utilizes the magnetic force of the gravity of balancing weight and strong magnet that air door is hung down into to automatically reset behind the several angle and closes.Its simple operation can not occur forgetting the phenomenon that resets after air door is opened.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, air door 3 is fastened on the Blower Housing 7 by screw 6 after being fixed into one by axle of the air door 5 and 4 activities of air door seat.
The balancing weight 1 of assembly welding hollow shape below air door 3, and the built-in strong magnet 2 of empty therein part, above-mentioned balancing weight 1 and strong magnet 2 are arbitrary shape.The effect of its balancing weight 1 and strong magnet 2 is: after air door 3 is opened, utilize the magnetic force of the gravity of balancing weight 1 and strong magnet 2 to make air door 3 hang down into behind the several angle effect by magnetic force earlier again and automatically reset and close.
Sometimes, for convenience balancing weight or strong magnet can be installed on air door directly.
