Description

Technical Field

[0001] The present application relates to the technical field of small desktop fans, and in particular to a desktop fan. Background Art

[0002] In summer or hot and humid seasons, fans are essential electrical appliances in daily life. By driving the rotation of fan blades, the air circulation around is accelerated, which is used to relieve the heat and make people feel cool. However, most traditional fans are large in size, heavy in weight, occupy a large space, and are inconvenient to carry, which will be subject to certain restrictions in use.

[0003] Then the desktop fan has become a new type of small appliance that is gradually becoming popular in offices. The desktop fan has a simple structure and can be used by directly connecting it to the computer host through a power cord. Related prior art, such as the Chinese patent application "A desktop fan", application number: CN201820081986.3; discloses a fan head, a base and a bracket, wherein a rotating connection mechanism is provided at the connection between the fan head and the bracket, wherein the rotating connection mechanism includes a clamping groove fixedly connected to the fan head, a connector and a spring seat arranged at the end of the bracket, wherein the two clamping surfaces of the clamping groove are arranged in parallel, the connector is in the shape of a flat column and the thickness is consistent with the distance between the two clamping surfaces of the clamping groove, a spring through hole is provided on one clamping surface of the clamping groove, and a spring slot is provided on one side surface of the connector adjacent to the spring through hole, and the spring seat passes through the spring through hole and is embedded in the spring slot. In the above patent application, the direction adjustment of the fan head is mainly realized by the combination of the clamping groove, the connector and the spring seat.

[0004] The above patent application only provides for adjustable pitch angle of the fan head, but does not provide for left-right adjustment of the fan head. Although desktop fans are small in size, users can directly move and adjust their direction. However, if users want to make the fan head shake during use to provide a circulating airflow, this is not possible. Utility Model Content
