Double-channel bladeless fan

Abstract

The double-channel bladeless fan comprises a fan supporting frame, supporting legs, an upper air outlet frame body, air guide barrels and a lower air outlet frame body, a driving base is movably installed in an installation groove through a rotating shaft, and the upper air outlet frame body and the lower air outlet frame body are fixedly installed at one ends of the two sets of air guide barrels correspondingly; a second air duct is formed between the first air deflector and the second air deflector; the movable driving seat is arranged in the mounting groove in the fan supporting frame, the upper air outlet frame body and the lower air outlet frame body are arranged on the upper portion and the lower portion of the driving seat correspondingly, the double-air-outlet-frame-body structural design is adopted, the air outlet area can be effectively increased, the fan is suitable for being used by multiple persons in a large scene, and the upper air outlet frame body and the lower air outlet frame body are pulled by the pull wire, so that the fan is more convenient to use. The upper air outlet frame body and the lower air outlet frame body can rotate towards the two sides, then the air outlet position is adjusted, air is supplied to users at different positions, the air volume of the upper air outlet frame body and the air volume of the lower air outlet frame body can be independently adjusted, and therefore a double-area air supply area is formed and meets the use requirements of different crowds.

Description

Technical field [0001] The present invention relates to an unemployed fan, particularly to a dual-channel bladeless fan, belonging to the field of fan technology. Background [0002] The traditional fan is usually composed of a motor, fan blade, base, etc., turn on the power supply, the motor rotates, drives the fan blade on the motor shaft to rotate and produce air flow, the air volume it produces blows to the human body, which can accelerate the evaporation of sweat moisture on the body surface, absorb a lot of heat through the evaporation of the body surface water, so that people feel cool, but when enjoying the coolness and comfort brought by the traditional fan, the high-speed rotating fan blade is also easy to cut the human finger, bringing safety hazards. The buzzing noise reduces the user's experience, and the removal and cleaning of the fan is also very convenient, which is a headache. [0003] In order to overcome the above shortcomings, the development of a leafless fa...

AI Technical Summary

Problems solved by technology

[0004] Existing bladeless fans all use a single fixed air outlet frame for air outlet design, and the air outlet angle and position are fixed, which cannot be used in a large scene with multiple people, nor can it be used for dual-zone control for different users , so that different air volume controls are used at different locations, and the existing bladeless fans all adopt a single oriented air outlet design, and the air outlet is designed to blow directly. Long-term blowing is likely to cause colds, colds, abdominal pain, diarrhea and other diseases, and high-speed blowing will cause The "sweating" situation
