Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a circulation fan. Background Art

[0002] A circulation fan is a device for generating airflow, including a support mechanism, a chassis mechanism and a head mechanism. The chassis mechanism is installed at the bottom of the support mechanism, and the head mechanism is installed at the top of the support mechanism. The head mechanism includes a fan blade and a motor for driving the fan blade to rotate. When the motor drives the fan blade to rotate, the fan blade compresses the air to generate airflow. Most existing circulation fans set the head mechanism as a whole. When the circulation fan starts the shaking function, the entire head mechanism shakes together, that is, the wind shield, the fan blade and the motor rotate together. This design method has some inconveniences in actual life. The left-right swinging fan shield is easy to cause bumps, and the left-right swinging fan shield needs to occupy more space than the static fan shield. For example, compared with the static fan shield, the left-right swinging fan shield obviously cannot be placed close to the corner of the wall. Summary of the invention

[0003] In view of this, the present invention discloses a circulation fan which can avoid collision and reduce occupied space.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A circulation fan, comprising:

[0006] Support mechanism;

[0007] A chassis mechanism, the chassis mechanism being mounted on the bottom of the support mechanism;

[0008] A head mechanism, which is mounted on the top of the support mechanism and is used to drive air flow;

[0009] Wherein, the head mechanism comprises:

[0010] Wind shield assembly;

[0011] A wind driving component, the wind driving component is arranged in the wind shield component, and the wind driving component includes a fan blade and a fan blade motor connected to the fan blade;

[0012] A driving mechanism is installed in the wind shield assembly and connected to the wind driving assembly, and is used to drive the fan motor to shake left and right and / or up and down relative to the wind shield assembly.

[0013] It can be seen from the above technical solution that the circulation fan disclosed in the present invention drives the fan blade motor to shake its head left and right and / or up and down relative to the fan cover assembly by arranging a driving mechanism in the fan cover assembly. In this way, the fan cover assembly can remain stationary during the process of the fan blade motor shaking its head left and right and / or up and down. In actual use, not only can the bumps caused by the rotation of the fan cover assembly be avoided, but also the space occupied by the circulation fan can be reduced.

[0032] After adopting the above technical solution, by setting the support mechanism 10 to adopt the telescopic frame 11, when the height of the head mechanism 30 needs to be adjusted, it is only necessary to grasp the head mechanism 30 and lift or press it down to a preset height, which is very convenient. Moreover, by setting the support mechanism 10 to adopt the telescopic frame 11, the height of the circulation fan 100 can be pressed down to a lower level as a whole, which is convenient for transportation.
