[0027] 1. The fan provided by the present invention can drive the blades to rotate when the main motor is working, so as to realize the normal blowing function of the fan. When the head needs to be pitched, the pitch angle of the head can be adjusted manually. When the head is adjusting the pitch angle, since the shaking motor is connected to the cover, it will move along an arc track in the vertical plane with the head relative to the base structure. When the pitch angle of the head is less than 90 degrees, the shaking motor drives the head to shake left and right. When the pitch angle of the head is equal to 90 degrees, the shaking motor drives the head to pitch and shake in the vertical plane. The head can swing at any pitch angle, so as to realize stepless pitch angle adjustment and shaking. Therefore, only one shaking motor needs to be set, so as to realize left and right shaking and up and down pitch shaking. The structure is simple and the cost is low.

[0028] 2. The fan provided by the present invention also includes a slide rail bracket, which can be swung on the base structure in a vertical plane, the slide rail bracket is arc-shaped, the shaking motor is fixed on the slide rail bracket, and the locking assembly is used to lock the position of the slide rail bracket. The user can adjust the pitch angle of the machine head by swinging the slide rail bracket relative to the base structure, which makes the operation safer. The pitch angle can also be adjusted during the operation and left and right swinging of the machine head, which is convenient for users to operate and use. The machine head can swing left and right at any pitch angle, realizing stepless pitch angle adjustment and shaking.

[0029] 3. The fan provided by the present invention, the locking assembly includes an arc-shaped rack and a spring bead. The arc-shaped rack is arranged on the side of the slide rail bracket facing the base structure; the spring bead is arranged on the base structure, and the spring bead is suitable for being inserted into the tooth groove of the arc-shaped rack. The spring bead specifically includes a spring and a bead body connected to the spring. When the slide rail bracket is manually moved to swing, the slide rail bracket will overcome the elastic force of the spring to swing. When the machine head is adjusted to a suitable pitch angle, the bead body automatically inserts into the corresponding tooth groove on the arc-shaped rack, thereby limiting the slide rail bracket to this position. The structure of the locking assembly is simple, and no additional operation is required by the user. The locking assembly will automatically lock, which is convenient for the user to use.

[0043] Example 1

[0044] Currently on the market, most fans use a single shaking motor to achieve a single shaking motion. Since a shaking motor can only control left and right shaking or up and down shaking motion, when the fan needs to shake left and right and up and down simultaneously, two shaking motors are required, the structural design is complex and the product cost is high.

[0045] For this reason, Figures 1 to 5 As shown, this embodiment provides a fan that can achieve both left and right shaking and up and down pitching and has low cost. In one embodiment, the fan includes a head, a base structure, a shaking motor 6, and a locking component.

[0047] The housing specifically includes a front net 1 and a rear net 2 , and a main motor 4 is disposed in a motor housing 5 .

[0048] The fan provided in this embodiment can drive the fan blades 3 to rotate when the main motor 4 is working, so as to realize the normal blowing function of the fan. When the head needs to be pitched, the pitch angle of the head can be adjusted manually. When the head is adjusting the pitch angle, since the shaking motor 6 is connected to the cover, it will move along an arc track in the vertical plane with the head relative to the base structure. When the shaking motor 6 is working, when the pitch angle of the head is less than 90 degrees, the shaking motor 6 drives the head to shake left and right. When the pitch angle of the head is equal to 90 degrees, the shaking motor 6 drives the head to pitch and shake in the vertical plane. The head can swing at any pitch angle, so as to realize stepless pitch angle adjustment and shaking. Therefore, the fan provided in this embodiment only needs to be provided with one shaking motor 6, which can realize left and right shaking and up and down pitching, and has a simple structure and low cost.
