Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be described in further detail with reference to the accompanying drawing 1:

as shown in fig. 1, the utility model provides a wall fan of shaking head, include:

the fan head comprises a fan head 1, a base 2 and a shaking head structure 3, wherein the rear cover of the fan head 1 is fixedly connected with a shaking head rod 5, the base 2 comprises a rear shell 22 and a panel 21, the shaking head structure 3 is positioned in the rear shell 22, and the shaking head rod 5 penetrates through the panel 21 and is rotatably connected with the shaking head structure 3;

referring to fig. 2, the oscillating structure 3 includes a motor 31, a connecting rod 33 and an eccentric block 32, one end of the eccentric block 32 is provided with a first protruding rod, the other end is provided with a groove connected with an output shaft of the motor 31, two opposite ends of the connecting rod 33 are provided with connecting holes, and the oscillating rod 5 and the first protruding rod are respectively connected with the connecting holes.

Wherein, structure 3 of shaking head still includes bearing 36 and with bearing 36 range upon range of fixed bolster 35 that sets up, the fixed bolster 35 center is equipped with the first through-hole that the pole of shaking the head passed that supplies, and fixed bolster 35 and panel 21 fixed connection are equipped with the second through-hole that the pole of shaking the head passed that supplies on the panel 21, and bearing 36 is located second through-hole department. The bearing plays a role in lubrication, plays a role in connection of bearing up and down, and is more convenient for force transmission.

Referring to fig. 3, the head shaking structure 3 further includes a head shaking support 34, the head shaking support 34 is in a shape of a circular disc 341, a protruding block 342 connected with the head shaking rod 5 in a matching manner is arranged at the center of one end of the head shaking support 34, and a second protruding rod 343 connected with the connecting hole in a matching manner is arranged at the edge of the other end.
