Example one
With reference to fig. 1 and fig. 2, a fan oscillating apparatus according to an embodiment of the present invention includes a driving member 1, a rotating member 2 and a fixing member 3, the driving member 1 is connected to a head 14 of a fan, the fixing member 3 is connected to a body of the fan, the driving member 1 includes a driving member body (not shown in the figure) and a driving shaft 4, the driving member body is fixedly connected to the rotating member 2, and the head 14 swings relative to the body of the fan through the driving of the driving member 1; the driving shaft 4 is fixedly connected with the fixing part 3; the rotating part 2 is sleeved on the fixing part 3 and rotates relative to the fixing part 3 under the driving of the driving part 1.
Because the motions are relative, after the fixing member 3 is fixed (because the fixing member 3 is connected to the body of the fan, and the body of the fan is usually fixed), the rotating member 2 rotates relative to the fixing member 3 (because the driving member 1 is connected to the head 14 of the fan, and the driving member body is connected to the rotating member 2), so that the purpose of driving the rotating member 2 and the head 14 to rotate relative to the base 15 when the driving shaft 4 rotates can be achieved. The body of the fan can be a base 15 of the fan or a column 16 of the fan, preferably the base 15 of the fan, and it should be noted that in this embodiment, the fan includes a body of the fan and a head 14, and an air supply assembly is disposed in the head 14. Through the fan oscillating device in the embodiment, the head 14 can swing relative to the body of the fan, thereby expanding the air supply range of the air supply device.
The embodiment of the utility model provides a fan device of shaking head, through drive shaft 4 with driving piece 1 and 3 fixed connection of mounting, with driving piece body and rotation 2 fixed connection to rotate 2 covers and establish in 3 peripheries of mounting, with the fixed back of the body of mounting 3 with the fan, and just can realize driving through the drive of driving piece 1 and rotate 2 for 3 pivoted purposes of mounting, and then can realize the function that the drive fan shaken the head. The fan oscillating device is applied to the fan, so that the structure of the fan oscillating device in the prior art can be greatly simplified. In addition, the fan oscillating device directly uses the driving part 1 to drive the rotating part 2 to rotate relative to the fixing part 3, so the fan oscillating device also has the advantages of high transmission stability, high controllability and the like.
Particularly, because the embodiment of the present invention provides a fan oscillating device, which directly uses the driving element 1 to drive the rotating element 2 to rotate relative to the fixing element 3, so that a motor with relatively smaller torque can be used as the driving element 1, and thus, the purposes of reducing cost and reducing energy consumption can be achieved.
In this embodiment, the driving member 1 is a motor, the motor is fixedly connected to the rotating member 2, and an output shaft of the motor (i.e., a driving shaft 4 of the driving member 1) is connected to the fixing member 3. The rotating part 2 may be a tubular structure, and likewise the stationary part 3 may be a tubular structure. Generally, the output shaft of the motor has a smaller diameter than the motor itself, so the rotating member 2 in this embodiment is sleeved on the outer periphery of the fixing member 3. Thus, when the fixed part 3 is fixed, the driving part 1 is started again to rotate the driving shaft 4 of the driving part 1 relative to the driving part body, so that the purpose that the driving part 1 drives the rotating part 2 to rotate relative to the fixed part 3 can be achieved.
Therefore, when the fan oscillating device is applied to the electric fan, the oscillating function of the electric fan can be realized, the structure of the electric fan oscillating device is greatly simplified, and the transmission stability of the electric fan oscillating device is also improved. In addition, because the driving member 1 directly drives the rotating member 2 to rotate, the controllability is greatly improved compared with the prior art.
As shown in fig. 1 and 2, in order to further improve the stability of the connection between the driving shaft 4 and the fixing member 3, in a preferred embodiment, an intermediate connecting member 5 is further connected between the driving shaft 4 and the fixing member 3. In this embodiment, the intermediate link 5 may be a crank or other member capable of performing the above-described function.
In this way, since the intermediate link 5 is provided, in the present embodiment, one end of the intermediate link 5 is fixedly connected to one end of the fixing member 3, and the other end of the intermediate link 5 is fixedly connected to the drive shaft 4. As shown in fig. 1 and 2, taking a crank as an example, the lower end of the crank can be directly sleeved on the upper end of the fixing member 3 and fixedly connected therewith, and the upper end of the driving can be fixedly connected with the driving shaft 4 by key connection or the like.
When the driving shaft 4 rotates, since the middle connecting member 5 is fixedly connected to the fixed member 3 and the fixed member 3 is fixed, the relative positions of the driving shaft 4, the middle connecting member 5 and the fixed member 3 are all kept unchanged, and the driving member 1 drives the rotating member 2 to rotate relative to the fixed member 3.
In addition, the intermediate coupling member 5 is provided to prevent the rotation member 2 from being separated from the fixed member 3. For example, an annular step surface may be provided on the inner side surface of the rotating member 2, and the lower end surface of the crank may be pressed against the annular step surface.
Further, a bearing 8 is provided between the fixed member 3 and the rotating member 2. Sliding friction between the fixing part 3 and the rotating part 2 can be converted into rolling friction by arranging the bearing 8, so that the friction force between the fixing part and the rotating part is smaller, and the rotating noise is reduced. In addition, the friction force between the rotating part 2 and the fixing part 3 is reduced by the bearing 8, so that the driving force of the driving rotating part 2 relative to the fixing part 3 is further reduced, and the aim of driving the rotating part and the fixing part to rotate relative to each other by selecting a motor with smaller torque is further ensured.
In addition, in order to prevent the bearing 8 from being detached from the fixing member 3, the crank may be used to press the bearing 8 to prevent it from being detached; a plurality of sets of bearings 8 can be arranged between the rotating member 2 and the fixed member 3 according to actual use requirements.
Further, a bottom plate 9 is arranged at the bottom end of the fixing member 3, and a first supporting seat 10 is connected to the bottom plate 9. Specifically, referring to fig. 1, the stability of the fixing member 3 in the fixed state can be further improved by providing the bottom plate 9; the first support 10 provided on the base plate 9 may serve as a weight to further improve the stability of the fixing member 3, and the base plate 9 may serve as a base 15 of the fan. Wherein the bottom plate 9 may be circular, rectangular, etc., preferably circular. The first supporting seat 10 can be fixedly connected with the bottom plate 9 or detachably connected with the bottom plate.
Furthermore, since the first supporting seat 10 is provided, it is equivalent to increase the radial fixing dimension of the rotation member 2, that is, the stability of the rotation member 2 can be improved by the first supporting seat 10. Therefore, the structure for fixing the rotating part 2 can be relatively small along the axial size of the rotating part 2, so that the axial thickness space of the fixing rotating part 2 is saved, and the industrial design is convenient for manufacturing the base 15 of the fan.
Accordingly, in order to ensure the coaxiality of the rotating member 2 with the fixed member 3 in the rotating state, a second support seat 11 is provided at a position opposite to the first support seat 10 on the rotating member 2. In this way, the rotation of the rotation element 2 is not only dependent on its cooperation with the fixing element 3 in the vertical plane, but also on the cooperation of the second support seat 11 with the first support seat 10 in the horizontal plane. That is, the relative positions of the rotation member 2 and the fixed member 3 can be defined from two planes, thereby improving the stability when the rotation member 2 rotates. The second supporting seat 11 may be directly integrated into the lower end of the rotating member 2, or may be fixedly connected to the rotating member 2 in other manners.
In the present embodiment, the outer diameter of the first support base 10 is equal to or different from the outer diameter of the bottom plate 9. The following three cases can be roughly classified:
firstly, as shown in fig. 3, the outer diameter of the first supporting seat 10 is equal to the outer diameter of the bottom plate 9;
secondly, as shown in fig. 4, the outer diameter of the first supporting seat 10 is larger than that of the bottom plate 9; in this case, when the bottom plate 9 is used as a base of the fan, the appearance effect of the concealed base can be achieved;
thirdly, as shown in fig. 5, the first supporting seat 10 and the bottom plate 9 can be made into an integral structure, so as to simplify the design of the base 15 of the fan, and the head 14 of the fan is directly inserted on the base 15 by the upright post 16, and the function of shaking the head on the base 15 (including the first supporting seat 10 and the bottom plate 9) is realized.
Preferably, the rolling friction member 12 disposed between the first support seat 10 and the second support seat 11 converts sliding friction therebetween into rolling friction, so that friction force therebetween is smaller, and rotation noise is further reduced. Wherein the rolling friction member 12 may be a steel ball or the like.
In a preferred embodiment, the rotary part 2 is provided with a detection element 6 on the side facing the fixed part 3, and the fixed part 3 and/or the intermediate connecting part 5 is provided with a detected element 7.
The detecting member 6 may be a hall sensor, and the detecting member 7 may be a magnetic member such as a magnet. Of course, other elements such as a displacement sensor and a photoelectric sensor that can perform the above functions may be used for the detecting member 6 and the detected member 7. And the positions of the detecting part 6 and the detected part 7 can be interchanged.
Referring to fig. 1 and 2, the magnet may be mounted on the crank, the hall sensor may be mounted on the rotating member 2, and the hall sensor and the magnet may sense within a specific distance range, so that the rotating member 2 may be precisely positioned at any position through a program, and thus the fan may be precisely positioned at any rotating position in a rotating state or a stationary state.
Furthermore, the rotating part 2 and/or the fixing part 3 and/or the middle connecting part 5 are/is provided with a threading hole 13, so that a power supply cable or a signal cable can be conveniently threaded up and down.

As shown in fig. 3 to 5, the second embodiment of the present invention provides a fan, which includes a fan body and a head 14 installed on the fan body, wherein an air supply device is disposed in the head 14, and the second embodiment of the present invention further includes a head shaking device of the fan, the head 14 is fixedly connected to a driving member body, and the fan body is fixedly connected to a fixing member 3.
In this embodiment, the driving member body can be fixed in the head 14, the base 15 of the fan is fixedly connected with the fixing member 3, and the rotating member 2 of the oscillating device of the fan in the first embodiment can be arranged in the upright post 16 of the fan, or the rotating member 2 can be directly used as the upright post 16 of the fan.
Thus, when the driving member 1 rotates, the base 15 of the fan is fixed, and the base 15 is fixedly connected with the fixing member 3, and the driving member body is arranged in the machine head 14, so that the purpose of driving the machine head 14 to rotate relative to the base 15 or the upright post 16 can be achieved. The head 14 can swing relative to the body of the fan, thereby enlarging the air supply range of the air supply device. Moreover, since the fan in the second embodiment uses the fan oscillating device in the first embodiment, the structure of the oscillating device of the fan in the prior art can be greatly simplified. In addition, the fan also has the advantages of high transmission stability, high controllability and the like.
