Referring to FIGS. 1-9 , an oscillating mechanism 100 of a household appliance according to an embodiment of the present invention includes an oscillating bracket 10 , a driving device 20 , a gear cover 30 , a driving gear 40 and a base 50 . The driving device 20 is installed on the oscillating head bracket 10 . The gear cover 30 is fixedly connected with the oscillating head bracket 10 . The drive gear 40 is connected to the drive device 20 . The swing bracket 10 is rotatably connected to the base 50 . The driving device 20 is used to drive the driving gear 40 to rotate relative to the base 50 so as to drive the oscillating head bracket 10 to rotate to a predetermined position relative to the base 50 . When in a predetermined position, the gear cover 30 is used to limit the rotation of the oscillating head bracket 10 so that the oscillating head bracket 10 can rotate in reverse.

In the oscillating head mechanism 100 of the household appliance in the embodiment of the present invention, when the oscillating head bracket 10 rotates to a predetermined position, the gear cover 30 can limit the rotation of the oscillating head bracket 10 and make the oscillating head bracket 10 rotate in reverse, thereby effectively preventing the oscillating head bracket 10 from suddenly appearing. Stopping causes the shaking head mechanism 100 of the household appliance to vibrate, which realizes the stable operation of the shaking head mechanism 100 of the household appliance.

In one embodiment, the gear cover 30 includes a gear cover stopper 31 . The base 50 includes a base stopper 51 . When in the predetermined position, the gear cover stopper 31 elastically resists the base stopper 51 .

In this way, when the oscillating head bracket 10 rotates to a predetermined position, the gear cover stopper 31 elastically resists the base stopper 51, which can cause the oscillating head bracket 10 to buffer and stop rotating at the predetermined position and then reverse rotation, thereby effectively preventing the oscillating head bracket from 10, the emergency stop causes the oscillating mechanism 100 of the household appliance to vibrate, thereby improving the running stability of the oscillating mechanism 100 of the household appliance.

Specifically, the design of the predetermined position determines the setting positions of the gear cover limiting member 31 and the base limiting member 51 . When the predetermined positions are different, the setting positions of the gear cover limiter 31 and the base limiter 51 are also different. In this way, the oscillating mechanism 100 of the household appliance can realize different angles of rotation.

In the embodiment of the present invention, the limiter 31 of the gear cover includes a first limiter 31 a and a second limiter (not shown in the figure, which is blocked on the other side of the gear cover 30 ). The base limiting member 51 includes a third elastic limiting member 51a and a fourth elastic limiting member 51b. The predetermined positions include a first position and a second position. When in the first position, the first limiting member 31a elastically resists the third limiting member 51a.

Specifically, in the embodiment of the present invention, the first limiting member 31 a and the second limiting member are ribs formed on the gear cover 30 . The third limiting member 51 a and the fourth limiting member 51 b are elastic pieces formed on the base 50 , and both the third limiting member 51 a and the fourth limiting member 51 b are substantially J-shaped.

When in the first position, the first limiting member 31a elastically resists the third limiting member 51a. Thus, the oscillating bracket 10 buffers and stops rotating, and then reverses and rotates toward the second position. In the second position, the second limiting member elastically resists the fourth limiting member 51b, so that the oscillating head bracket 10 buffers and stops rotating, and then reverses to rotate toward the first position. In this way, the oscillating head bracket 10 can rotate back and forth between the first position and the second position.

In this way, when the oscillating head bracket 10 is turned to the first position and the second position, the oscillating head bracket 10 can be buffered to stop rotating and then reversed to rotate, thereby preventing the oscillating head bracket 10 from suddenly stopping and causing the oscillating head mechanism 100 of the household appliance to vibrate. phenomenon, thereby realizing the stable operation of the shaking head mechanism 100 of the household appliance.

Specifically, in the embodiment of the present invention, the angle between the first position and the second position can be set according to specific actual conditions. For example, the angle between the first position and the second position can be set to 60 degrees, so that the oscillating head bracket 10 can be rotated back and forth within an angle range of 60 degrees.

In one embodiment, the gear cover 30 includes a gear cover stop 32 . The base 50 includes a base stop 52 . When at the predetermined position, the interference between the gear cover stopper 31 and the base stopper 51 fails, the gear cover stopper 32 abuts against the base stopper 52 to stop the rotation of the oscillating head bracket 10 .

In this way, in one example, when the base stopper 51 breaks and the swing head bracket 10 rotates to a predetermined position, the gear cover stopper 31 cannot interfere with the base stopper 51, so that the gear cover stopper 31 and the base stopper 51 The interference of the base stopper 51 is invalid, and the gear cover stopper 32 can abut against the base stopper 52 to stop the rotation of the oscillating head bracket 10, so as to prevent the oscillating head stand 10 from moving between the gear cover stopper 31 and the base stopper 51.
