Abstract

The invention relates to an energy-saving desk fan with adjustable air volume. The energy-saving desk fan comprises a desk fan main body and a sealing cover plate, fan blades and a fan cover are arranged on the desk fan body, the fan blades are rotationally arranged on the desk fan body, and the fan cover surrounds the fan blades; first ventilation holes are formed in the side surface and the end surface of the fan cover; the sealing cover plate is rotationally arranged in the center of the end face of the fan cover, and a second ventilation hole is formed in the sealing cover plate; the sealing cover plate can cover the first ventilation hole. The sealing cover plate shields the first ventilation hole, the second ventilation hole can communicate with the first ventilation hole, the range of the first ventilation hole covered by the sealing cover plate can be adjusted by rotating the sealing cover plate, then the actual opening size of the first ventilation hole is adjusted, and the air volume of the fan is continuously adjusted; a step speed regulation mechanism or a stepless speed regulation mechanism is not arranged, electric energy is saved, air volume can be regulated through the sealing cover plate, the internal structure of the desk fan is simplified, resources and energy are saved, and the desk fan has the advantages of energy conservation and environmental protection; the method is easy to adjust and low in production cost, and has popularization significance.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an energy-saving desk fan with adjustable air volume. Background technique [0002] The fan is a device driven by electricity to generate airflow. After the fan is powered on, the blades rotate to form natural wind to achieve the effect of heat dissipation. In order to be convenient for users to use, fans are derived into table fans. [0003] Desk fan is a household appliance that people often use in summer. It is easy to carry and use; traditional fans generally adjust the speed of the fan blades by adjusting the speed of the motor to adjust the air volume of the fan, but the speed adjustment consumes energy and does not have energy-saving features. The advantages of environmental protection. The speed regulation of the motor is generally divided into step regulation and stepless regulation. The stepless adjustment method cannot well adapt to the body feeling of each user, and u...
