Problems solved by technology

[0002] The existing fan drives the blades to rotate through the motor, and the air is pressurized and accelerated by the blades and then blows to the user. Be careful that it will cause injury, although most fans use outer covers to surround the blades to reduce danger; second, the blades and outer covers are difficult to clean; third, noise will be generated during the rotation of the blades, which will disturb users; Because the airflow changes when passing through the surface of the blade, the wind blown out is not uniform, and the user will feel a burst of strong wind like a pulse

Abstract

The invention discloses a blade-free fan. The blade-free fan is mainly composed of a base and an annular airflow jetting device which is located on the base, wherein a power device is arranged in the base, an impeller is arranged in the airflow jetting device, an air inlet is formed in the position where the airflow jetting device is connected with the base, air is blown out through an air jet hole after being pressurized by the impeller, in this way, high air pressure is guaranteed, and a large amount of air can be sucked in an entrainment mode and blown out forwards.

Description

technical field [0001] The invention relates to a bladeless fan, which belongs to the optimization technology of the fan. Background technique [0002] The existing fan drives the blades to rotate through the motor, and the air is pressurized and accelerated by the blades and then blows to the user. Be careful that it will cause injury, although most fans use outer covers to surround the blades to reduce danger; second, the blades and outer covers are difficult to clean; third, noise will be generated during the rotation of the blades, which will disturb users; Because the airflow changes when passing through the surface of the blade, the wind blown out is not uniform, and the user will feel a burst of strong wind like a pulse. [0003] In the patent documents with the application number 200810177843.3 and the application number 200810177844.8, a fan is disclosed, which consists of a base and an annular exhaust port installed on the base. The inner channel of the airflow a...
