Abstract
The utility model relates to an air blowing device with adjustable air volume, which is composed of a motor, blades, a start device and a blade angle changing mechanism, and the blade angle changing mechanism is composed of a rotor 1, a controlling motor 2, a rotating disk 3, a tooth ring 4 and a gearwheel 5. The rotor 1 is fixed on the rotary shaft of the motor, and the controlling motor 2 is fixed in the rotor 1. The rotating disk 3 is fixed on the rotary shaft of the controlling motor 2, the tooth ring 4 is fixed on the rotating disk 3, and the tooth ring 4 is engaged and connected with the gearwheel 5 on the blade bottom. The blade angle can be changed in the process of air blowing at any time via the controlling motor 2 for adjusting the air blowing volume, and the utility model can be used as various air blowing and adjusting devices on fans, blower fans, fume extractors, etc.
Description
The utility model belongs to the technical field of blast device, is specifically related to the adjustable blast device of a kind of air quantity.
The air quantity of existing blast device is regulated, generally be to regulate the height of supplying with the blast device electric moter voltage by electric apparatus control apparatus to realize with the control rotating speed, but because this electric apparatus control apparatus has elements such as induction reactance, resistance, waste energy, and for some blast device by synchronous machine drives, because rotating speed is constant, so its exhaust air rate also is constant, unadjustable.In order to overcome the above problems, Chinese patent CN2094633 discloses the wheeled air quantity controlling mechanism of a kind of micro ceiling fan, it connects annular rolling disc in the bottom of fan drum, on the annular rolling disc tooth bar is arranged, the blade link arm is installed on top at fan drum, on the blade link arm gear is arranged, wheel and rack matches, and blade link arm outer end links to each other with fan blade.After rotating annular rolling disc by hand, the rack drives gear rotates, the blade link arm is rotation and then, thereby the fan blade angle is changed, reach the purpose of regulating air quantity, because this air quantity controlling mechanism rotates annular rolling disc change fan blade angle by hand and regulates air quantity, can not regulate air quantity in the using process at any time and regulate inconvenient shortcoming so exist.
The purpose of this utility model is: a kind of quantity-adjustable at any time in use that overcomes the prior art shortcoming is provided, and need rotate the adjustable air quantity blast device that annular rolling disc is regulated air quantity by hand.
The purpose of this utility model is to realize like this, the blast device that the utility model air quantity is adjustable is by motor, flabellum, starting arrangement and fan blade angles change mechanism and form, fan blade angles changes mechanism by rotor, the control motor, gear, rolling disc and ring gear are formed, rotor is fixed on the rotatingshaft of motor, the control motor is fixed on the inside of rotor, fixing rolling disc on the rotatingshaft of control motor, fixing ring gear on the rolling disc, ring gear is connected with the gear engagement of flabellum bottom again, during use, the control motor is regulated fan blade angles by gear and ring gear, thereby reaches the purpose that the utility model blast device is regulated air quantity.
Advantage of the present utility model is that the adjustable blast device of air quantity that provides can change fan blade angles at any time and regulate air output and do not have danger in the air-supply process.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing, the structural drawing of the blast device that the utility model air quantity is adjustable.
With reference to accompanying drawing, the blast device that the utility model air quantity is adjustable changes mechanism by motor, flabellum, starting arrangement and fan blade angles and forms, fan blade angles changes mechanism and is made up of rotor (1), control motor (2), rolling disc (3), ring gear (4) and gear (5), rotor (1) is fixed on the rotatingshaft of motor, control motor (2) is fixed on the inside of rotor (1), fixing rolling disc (3) on the rotatingshaft of control motor (2), rolling disc (3) is gone up fixedly ring gear (4), and ring gear (4) gear (5) bottom flabellum again is connected with a joggle.When the blast device that this air quantity is adjustable in use need be regulated air quantity, driving rolling disc (3) by control motor (2) rotates, rolling disc (3) drives ring gear (4) and rotates, ring gear (4) driven gear (5) rotation again changes the fan blade angles angle, thereby reaches the purpose of regulating air quantity.
In order to make fan blade angles change the evenly stressed and raising stability of parts of mechanism, the ring gear (4 ') identical with ring gear (4) can be fixedly mounted on the inside and the corresponding position of ring gear (4) of rotor (1), ring gear (4 ') also meshes with gear (5).
Claims (2)
1, the adjustable blast device of a kind of air quantity, changing mechanism by motor, flabellum, starting arrangement and fan blade angles forms, it is characterized in that fan blade angles changes mechanism and is made up of rotor (1), control motor (2), rolling disc (3), ring gear (4) and gear (5), rotor (1) is fixed on the rotatingshaft of motor, control motor (2) is fixed on the inside of rotor (1), fixing rolling disc (3) on the rotatingshaft of control motor (2), rolling disc (3) is gone up fixedly ring gear (4), and ring gear (4) gear (5) bottom flabellum again is connected with a joggle.
2, the adjustable blast device of air quantity according to claim 1, it is characterized in that fan blade angles changes mechanism and also comprises ring gear (4 '), ring gear (4 ') be fixedly mounted on the inside of rotor (1) corresponding with ring gear (4) and with gear (5) position engaged on.
