[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] The following Figures 1 to 14 The present invention specifically describes an oscillating head device and a household appliance.

[0043] In the prior art, the driving device for shaking the head to realize the shaking head function is divided into a DC motor 10 and an AC motor 7. The AC motor 7 can only rotate in one direction and cannot be controlled, so the AC motor 7 can only use the four-bar linkage 3 mechanism to realize the reciprocating shaking head. In the current technology, it can only be realized by the four-bar linkage 3. The DC motor 10 can be controlled by the main board and can perform self-commutation and realize reciprocating shaking head.

[0044] The present invention provides an oscillating head device, which can be applied to any household appliance with an oscillating head function. Specifically, the household appliance can be configured as a fan. The fan is taken as an example for specific description herein, and other household appliances are also within the protection scope of the present invention.

[0045] An oscillating head device provided in an embodiment of the present invention is mainly used in fans. Existing fans are mainly driven by DC motors 10 or AC motors 7. However, in specific production practices, two fans with different structures are usually designed according to the two fans driven by AC motors 7 or DC motors 10, and the R&D cost and production cost are relatively high. The purpose of the present invention is to propose an oscillating head device that can be driven by both AC motor 7 and DC motor 10. In the same structural space, the oscillating head drive mode can be switched according to the power supply mode of the whole machine, thereby reducing the product development cost.

The rotating shaft 23 and the rotating hole 51 are plugged, and the driving member can drive the rotating shaft 5 to rotate, so that the rotating shaft 5 moves along the circumferential direction of the connecting plate 2.

[0049] Furthermore, a limiting rib 55 is provided on the rotating shaft 5 , and a limiting boss 24 is provided on the connecting plate 2 . The limiting boss 24 cooperates with the limiting rib 55 to limit the rotational position of the rotating shaft 5 and the connecting plate 2 .

[0050] Furthermore, a positioning hole 21 is provided on the connecting plate 2, a matching hole 61 is provided on the chassis 6, and a screw hole 11 is provided on the bottom plate 1. The screw hole 11, the positioning hole 21 and the matching hole 61 are concentrically positioned, and the bottom plate 1, the connecting plate 2 and the chassis 6 are fixedly connected by screws.

[0051] Some embodiments of the present invention provide an oscillating head device, in which the driving member is electrically connected to the wire 9, and the wiring design of the wire 9 in the oscillating head device is also particularly important. The driving member is electrically connected to the wire 9, the bracket 8 is provided with a first wiring groove 82, the rotating shaft 5 is provided with a second wiring groove 54, the connecting plate 2 is provided with a third wiring groove 27 and a fourth wiring groove 28, and the chassis 6 is provided with a buckle 62.

[0052] The structure and connection relationship provided in the above embodiment are the main connection structures in the oscillating device. The driving member is respectively a DC motor 10 or an AC motor 7 to be described below.

[0053] The driving member is an AC motor 7, which includes a first motor body. The first motor body is connected to a first main shaft 72, which is connected to a rotating structure. The rotating structure is connected to a connecting shaft 25 provided on the connecting member.

[0054] Further, the rotating structure includes a crank 4 and a connecting rod 3, the crank 4 is connected to the first main shaft 72, the connecting rod 3 is connected to the connecting shaft 25, the first main shaft 72 drives the rotation, and the connecting rod 3 is connected to the crank 4, so that the connecting rod 3 drives the connecting plate 2 to rotate, thereby realizing the rotation of the rotating shaft 5 relative to the connecting plate 2.

[0055] Furthermore, the driving member is a DC motor 10, which includes a second motor body and a second main shaft 101. The motor body and the bracket 8 are fixedly connected, and the second main shaft 101 and the first shaft hole 22 set on the rotating shaft 23 are plugged and fixed.

[0056] The DC motor 10 and the AC motor 7 are adapted through different connection structures. The DC motor 10 (direct drive solution): the motor can directly drive the connecting plate 2. The components used are the connecting plate 2, the rotating shaft 5, the chassis 6, the bottom plate 1 and other components. The AC motor 7 (four-link 3 drive solution): the AC motor 7 can use all the above DC parts, but it needs to add the crank 4 and the connecting rod 3 to reduce the production cost to a certain extent. Under the condition that the size of the same product remains unchanged and the form of the reciprocating shaking motion remains unchanged, the DC mode (direct drive) and the AC mode (four-link 3 drive) can be adapted.

[0057] The two driving modes of the DC motor 10 and the AC motor 7 are described in detail below.

[0058] Assembly under AC power supply mode: First, assemble the chassis 6 and the bracket 8 concentrically, install the second mounting hole 71 of the AC motor 7 corresponding to the position of the fixing hole 81 of the bracket 8, then install the mounting portion 83 of the bracket 8 shown in the rotating shaft 5 with the mounting portion 83 on the bracket 8, and align the first mounting hole 53 on the rotating shaft 5 with the bracket 8 and the second mounting hole 71 of the AC motor 7 and screw them in to fix. At this time, the bracket 8 and its fan head, rotating shaft 5, and AC motor 7 are fixed without relative displacement. Then assemble the D-type shaft hole 31 shown in the crank 4 concentrically with the D-type main shaft shown in the AC motor 7. Then assemble the rotating shaft 23 of the connecting plate 2 concentrically with the rotating hole 51 of the rotating shaft 5 to perform circumferential motion friction, and make the slide rail 52 of the rotating shaft 5 cooperate with the slide groove 26 of the connecting plate 2 to perform axial motion friction. And make the positioning hole 21 shown in the connecting plate 2 and the matching hole 61 shown in the chassis 6 concentrically positioned. Then, one end of the shaft hole 31 of the connecting rod 3 is concentrically assembled with the mounting shaft 41 of the crank 4, and the other end is concentrically assembled with the connecting shaft 25 of the connecting plate 2. Finally, the wiring arrangement is completed, and finally, the screw hole 11 of the bottom plate 1 is concentrically positioned with the matching hole 61 of the chassis 6 and the positioning hole 21 on the connecting plate 2, and screws are driven in to fix them. At this time, the bottom plate 1, the chassis 6, and the connecting plate 2 are fixed without relative movement.

[0059] Working principle of AC motor 7: AC motor 7 is fixed on bracket 8 (machine head), the motor drives crank 4, connecting rod 3 is fixed to the base (chassis 6), and bracket 8 is driven by four-link 3 mechanism to perform reciprocating shaking motion with the rotating shaft 23 and the rotating hole 51 at the matching position of rotating shaft 5 and connecting plate 2 as the center of rotation.

[0060] Under the DC power supply mode, the chassis 6 and the bracket 8 are assembled as above, and the third mounting hole 102 shown in the DC motor 10 is concentrically positioned with the fixing hole 81 on the bracket 8, and then the matching portion 56 shown in the rotating shaft 5 is installed with the mounting portion 83 of the bracket 8, and the first mounting hole 53 on the rotating shaft 5 is aligned with the bracket 8 and the third mounting hole 102 on the DC motor 10, and screwed in to fix. At this time, the bracket 8 and the fan head thereon (not included in the plan, not described), the rotating shaft 5, and the AC motor 7 are fixed without relative displacement. Then the double D-shaped shaft shown in the DC motor 10 is concentrically matched with the double D-shaped shaft shown in the connecting plate 2, and then the rotating shaft 23 of the connecting plate 2 is concentrically assembled with the rotating hole 51 shown in the rotating shaft 5 for circumferential motion friction, and the slide rail 52 of the rotating shaft 5 is matched with the slide groove 26 of the connecting plate 2 for axial motion friction. The subsequent assembly is the same as the above-mentioned AC power supply mode.

[0061] Working principle of DC motor 10: AC motor 7 is fixed on bracket 8 (machine head), and the motor main shaft drives connecting plate 2. Further, bracket 8 is driven to perform reciprocating shaking motion with rotating shaft 23 and rotating hole 51 at the matching position of rotating shaft 5 and connecting plate 2 as the center of rotation.

[0062] The invention also discloses a household appliance, which comprises the shaking head device as described above.

[0063] The shaking device of the present invention uses only two main moving parts to realize the left and right shaking structure of the fan, and the assembly is simple and the transmission is stable. The design adopts both the AC four-link 3 driving mode and the DC direct driving mode, so that the same reciprocating shaking motion can be achieved under different power supply conditions (different driving modes) of the same product, reducing the development cost. A universal chassis 6 structure and wiring method are designed along with the structure.
