The blade 2 is pivotally disposed on the body 1, the blade 2 has a retracted position and an extended position, and it should be noted that, in a plane parallel to the body 1, when the blade 2 is located at the retracted position, the blade 2 rotates towards the center of the body 1, and when the blade 2 is located at the extended position, the blade 2 rotates towards a direction away from the body 1, so that the blade 2 is extended. The body 1 has a first drive member 9 (i.e. an electric motor) by which the body 1 is driven to rotate to move the blade 2 from the retracted position to the extended position under the influence of centrifugal force against the weight of the blade 2 and the second drive member 3.
The receiving portion is connected to the blade 2, the receiving portion is used for driving the blade 2 to move from the extending position to the retracting position, the receiving portion has a second driving member 3, the second driving member 3 is connected to the blade 2, it should be noted that the second driving member 3 is not limited to be directly connected to the blade 2, the second driving member 3 may be indirectly connected to the blade 2, the second driving member 3 drives the blade 2 to move from the extending position to the retracting position, and the second driving member 3 is suitable for driving the blade 2 to move from the extending position to the retracting position through gravity.
Wherein, blade 2 has blade rotating part 21 and the rope body 5, and blade rotating part 21 rotationally sets up in body 1, and second driving piece 3 is connected with blade rotating part 21 through the rope body 5, and the first end of the rope body 5 links to each other with second driving piece 3, and the second end of the rope body 5 links to each other with blade rotating part, and it needs to explain that, the upper end and the blade rotating part 21 of the rope body 5 are connected, and the lower extreme and the second driving piece 3 of the rope body 5 are connected. The lower surface of the body 1 may be provided with a roller 6, the roller 6 may be supported below the rope body 5,
in particular, the second driving member 3 is adapted to drive the blade 2 by gravity from the extended position to the retracted position, while the second driving member 3 is adapted to hold the blade 2 in the retracted position by gravity, it being explained that when the blade 2 is in the retracted position, the second driving member 3 can hold the blade 2 in the retracted position by gravity, and the blade 2 can be made to overcome the gravity of the second driving member 3 and the blade 2 by rotating the body 1 under the centrifugal force, thereby causing the blade 2 to move from the retracted position to the extended position.
Wherein, when needing air supply arrangement 10 to blow, air supply arrangement 10's motor 9 drive body 1 rotates, body 1 slew velocity reaches the predetermined value after, overcome the gravity of second driving piece 3 and blade 2 under the effect of centrifugal force and make blade rotating part 21 take blade 2 to rotate relative to body 1, rope body 5 is pulling second driving piece 3 and is ascending this moment, thereby make blade 2 throw away, after blade 2 stretches out completely (namely blade 2 is located the extension position back), blade rotating part 21 takes blade 2 and follows body 1 and rotate with the same speed together, realize air supply arrangement 10's the blowing. When the air supply device 10 is required to stop working, the motor 9 stops working, after the rotating speed of the body 1 is smaller than a preset value, the gravity of the second driving piece 3 is larger than the centrifugal force, the second driving piece 3 moves downwards, the second driving piece 3 pulls the blade rotating part 21 through the rope body 5 to drive the blade 2 to rotate from the extending position to the withdrawing position, and therefore the blade 2 is kept at the withdrawing position. When blades 2 of air supply device 10 do not work, set up like this and can contract blade 2 to the position of withdrawing, can avoid gathering the dust on the blade 2 to can reduce user's clean blade 2 number of times, and, also can reduce air supply device 10's volume, can reduce air supply device 10 and occupy the indoor space, also can make air supply device 10 more pleasing to the eye. Meanwhile, compared with the prior art, after the air supply device 10 is used for a long time, the blades 2 can be guaranteed to be normally contracted to the withdrawing position, so that the working reliability of the air supply device 10 can be guaranteed, and the problem that the blades of the existing air supply device are difficult to normally return can be solved. In addition, the blower device 10 of the present application has a simple structure, and can reduce the manufacturing cost of the blower device 10 and improve the operation stability of the blower device 10.
In addition, support in the rope body 5 below through cylinder 6, can make the rotary motion of blade rotating part 21 convert the upward motion of second driving piece 3 into, also can make the downward motion of second driving piece 3 convert the rotary motion of blade rotating part 21 into, when second driving piece 3 moves along the up-and-down direction, cylinder 6 can play the guide effect to rope body 5, can make things convenient for the removal of rope body 5, thereby can promote the removal speed that second driving piece 3 rises and descends, and then can promote the opening and the speed of withdrawing of blade 2, and, also, can reduce the wearing and tearing of rope body 5, can prolong the life of rope body 5.
