Embodiment 1

[0016] Referring to Fig. 2, this is an embodiment in which the connecting rod and the swing rod are connected by hinges according to the present invention. In this embodiment, the swing fan is mainly composed of a motor 1 , a transmission III, a linkage mechanism I, a balance device II, a casing, a base 4 and a fan blade 3 . The motor 1 is fixed on the shell and the base 4, the transmission III can be fixed with the motor 1, and can also be fixed with the shell and the base 4, the balance device II is installed on the linkage mechanism I, and the fan blade 3 is connected with the linkage mechanism I connected.

[0017] Link mechanism 1 of the present invention can be made up of crankshaft 8, connecting rod 12 and fork 14, and one end of connecting rod 12 links to each other with crankshaft 8 by hinge support 11, and the other end links to each other with fork 14 by fork hinge support 15, and swing link 14 and shell are hingedly connected with base 4.

Embodiment 2

[0023] Referring to Fig. 4, this is an embodiment in which the connecting rod and the swing rod are connected through a slider in the present invention. In this embodiment, the swing fan is also made up of a motor 1, a speed changer III, a link mechanism I, a balancing device II, a casing, a base 4, and a fan blade 3, and the composition of the link mechanism I and the balancing device II are the same as those of the balancing device II. Embodiment 1 is the same. Only one end of the connecting rod 12 is connected with the crankshaft 8 through the hinged support 11 of the crankshaft, and the other end is connected with the fork 14 through the slide block 18 . With the swing shaft 13 of the swing link 14 as the boundary, the slider 18 can be on the same side of the fan blade 3 (see Figure 5 ), of course it can also be on the other side of the fan blade

[0024] Referring to Fig. 2 or Fig. 4, during use, when motor 1 rotates and forms required rotating speed by speed changer I...

Abstract

The oscillating fan without vibration is provided with a balancing mechanism installed on a link rod mechanism, so the weight center of the moving mechanism is shifted onto the oscillating shaft or rotating shaft to balance the inertial force and realize the dynamic balance. The present invention has inertial force moment automatically balancing the motor input moment, bearing resistance moment and working resistance moment and it has reasonable and novel design, small volume and low noise.

Description

technical field [0001] The invention relates to an electric fan, in particular to a vibration-eliminating oscillating fan, which simulates the swaying action of an artificial hand-operated fan, is suitable for cooling the human body and flowing air, and is especially suitable for the elderly, children and other infirm people to cool off. Background technique [0002] The structure of the swing fan in the prior art is as follows: figure 1 As shown, it mainly consists of a motor 1', a rotation-swing conversion mechanism 2', a fan blade 3', and a housing and a base 4'. The rotation-swing conversion mechanism 2' can be variable speed, and the swing of the fan blade 3' The direction can be vertical plane or horizontal plane or inclined plane swing. However, in practical applications, there is a large imbalance in the motion mechanism, especially when the fan blade 3' is added. When the fan blade 3' swings back and forth, a large inertial force and moment of inertia are periodica...
