Abstract

The invention provides a bedside fan. The bedside fan comprises a support body capable of rotating up and down and swinging left and right, wherein the upper end of the support body is connected witha fan head; the lower end of the support body is detachably connected with a base used for being installed on a bedside; the support body is composed of a manual up-down head shaking mechanism and anelectric left-right swinging mechanism; the manual up-down head shaking mechanism comprises a fan fixing frame and a first connecting piece which are hinged to each other; a first hinge base is arranged at the rear end of the fan fixing frame and provided with a first pivot hole and an arc track groove; the electric left-right swinging mechanism comprises a second connecting piece and a motor support which are hinged to each other; the motor support is provided with a crank-link mechanism; and one end of the crank-link mechanism is connected to the motor support, and the other end of the crank-link mechanism is connected to the first connecting piece. The bedside fan achieves the left-right swinging air sweeping function through the crank-link mechanism, and compared with traditional circumferential rotation air sweeping, left-right swinging air sweeping can continuously aim at a user to supply air within one period, and effective cooling is achieved.

Description

technical field [0001] The invention relates to the field of electric fans, in particular to a bedside fan. Background technique [0002] There are many small fans suitable for bedside use on the market. In summary, they are divided into two categories, one is small desk fans and the other is small ceiling fans. Small desk fans can generally only be used in the work area, and some desk fans with fixtures can only be adapted to the surface of the desktop, not to the round tube guardrail on the bed. The function of shaking the head of the existing small fan is to do circular motion periodically, which has a disadvantage that everyone in the dormitory can only blow the wind when the fan head is aimed at the student in a cycle, which is very important for each student. , the sustained cooling effect is poor. [0003] Small ceiling fans are used in dormitory beds, and are generally installed on the top of the bed mosquito net, or hung up by pulling a rope through the mosquito n...
