Description

A fan with a left and right shaking head mechanism

technical field

The application relates to a fan with a left and right oscillating mechanism, which is suitable for the technical field of air conditioning equipment.

Background technique

Small table fans have technical advantages such as small size, easy to carry, and easy to operate, and have been used more and more. As shown in Figure 1, it shows a table fan that can manually adjust the blowing angle. The net cover is installed on the bracket, and the bracket and the bottom clamping assembly are connected by a shaking head mechanism. When it is necessary to adjust the blowing angle from left to right, manually rotate the bracket to make the bracket rotate relative to the upper splint, then rotate to the desired blowing angle and then stand still. Among them, between the head shaking mechanism and the upper splint, a silica gel pad or steel ball is generally arranged on the contact surface to achieve the head shaking effect. The setting of the silicone pad will increase the friction between the bracket and the upper splint, which will cause inconvenience in operation. Using steel balls will generate a lot of noise when shaking the head manually, and the positioning of the swinging head angle may not be achieved due to the wear of the steel balls after multiple swings.
