Description

A clip fan with good fixing effect and stable shaking head

technical field

The utility model relates to the technical field of fans, in particular to a clip fan with good fixing effect and stable shaking head.

Background technique

A fan refers to a device used to generate wind and cool in hot weather. An electric fan is a device that uses electricity to generate airflow. The fan inside is energized and then turned into natural wind to achieve the effect of cooling. Today, as air conditioners are gradually popularized, fans are still irreplaceable as a device for cooling in summer, because after years of development, the styles of fans have been varied, and fans are developing in the direction of small size, speed block, large air volume, and portability, especially In summer, when the electricity consumption peak is prone to power outages, the rechargeable fan is irreplaceable for the air conditioner.

Compared with ceiling fans, desk fans have the advantage of being easy to move, but they also have the disadvantage of fixed blowing direction. If the desk fan cannot swing its head during operation, it can only blow air directly in front of it, and it will cause the temperature in front of it. When the temperature is too low and the temperature on the side and rear is too high, a single fan can serve a larger area through the swinging motion of the fan, and there will not be too much difference in local temperature, so the table fan is basically With the shaking head function, the shaking method is basically swinging from side to side. It mainly uses the synchronous motor with its own reducer to make the fan swing its head. The synchronous motor rotates randomly, and automatically changes the direction of rotation when it is resisted, thus realizing the round-trip swing. Traditional In the process of shaking the head, the shaking table fan is prone to the problems of jamming, pulley sliding teeth, loud noise and abnormal noise, and the shaking angle is small. In order to solve the above problems, many enterprises have carried out the shaking mechanism and shaking characteristics to a great extent. , such as the use of a swing follower cam mechanism, the design of artificial control of the left and right shaking angles, the design of a three-dimensional shaking mechanism, etc. However, this complication of the mechanism does solve the problem of a small shaking angle and makes the shaking more stable, but the structure with more crossover adds more contact points, and the risk of loud noise and abnormal noise will also increase with time. Increase. And the table fan can only be placed on a fixed plane. If the plane position is small, its practicality is greatly reduced, so there are many fans with clips on the market, but the clamping effect of such fans is not good, and most of the transmission clip fans can only be used. Only by clamping the object can it be stably fixed, and the function has certain limitations, which is not conducive to the use of customers. Therefore, a clamping fan with good fixing effect and stable shaking of the head is proposed to solve the above problems.
