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, so most fans use outer covers to surround the blades to reduce danger; second, it is difficult to clean the blades and outer covers; third, there will be noise during the rotation of the blades, which will disturb users; Fourth, because the airflow changes when passing through

Abstract

The invention relates to a bladeless fan with double air nozzles. The fan consists of a base, an air flow injection device and an air supercharging device, wherein the air flow injection device is positioned above the base; the air supercharging device is of a water drop shape which is large in middle and small in two ends, is installed at the axial position of the air flow injection device, and is communicated with an air channel on the air flow injection device through an air pipe; a circle of annular first air injection openings are arranged surrounding the air channel; the middle part of the air supercharging device is provided with a shell; one end of the shell is connected with an intake cover, and the other end of the shell is connected with a dust-proof shell; and the shell is provided with a second air injection opening. Through the first air injection openings and the second air injection opening arranged coaxially, the weaker air force phenomenon at the middle part of a fanis avoided effectively.

Description

technical field [0001] The invention relates to a bladeless fan with double air jets, 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, so most fans use outer covers to surround the blades to reduce danger; second, it is difficult to clean the blades and outer covers; third, noises are produced during the rotation of the blades, which disturbs users; The 4th, because air-flow changes when passing through blade surface, the wind that blows out is not uniform, and the user can feel the strong wind of bursts like 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 ...
