Detailed Description

The technical solution of the present invention will be clearly and completely described by the following detailed description. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-9, the bladeless fan includes an air inlet (1), an inner casing (2), an outer casing (1), (3), a round casing (1), (4), an outer casing (2), (5), a round casing (2), (6), and a round casing (3), (7); the inlet channel (1) has one port fixed with a round shell (2), (6), one end of the round shell (2), (6) has a ring surface fixed with the outer ring surface of the round shell (3), (7), the inner wall of the round shell (3), (7) is provided with an inner shell (2), the other end of the round shell (2), (6) has a ring surface fixed with the outer ring surface of the outer shell (2), (5), the inner ring surface of the outer shell (2), (5) has a ring surface fixed with the round shell (1), (4), and the other ring surface of the round shell (1), (4) has an outer shell.

Preferably, the round shell 3(7) is a circular tube flat-cut concave ring body, the inner wall of the concave ring body is provided with an inner shell (2), and the inner shell (2) annularly penetrates through the inner wall of the concave ring body to be provided with an air outlet.

Preferably, the housing 1(3) is an annular body in the upper funnel portion.

Preferably, the housing 2(5) is an annular body in the upper funnel portion.

Preferably, the shell 1(3) is sleeved on the inner ring of the round shell 2 (6).

In this embodiment, through the design of circular arc, can realize that its atress is even under extreme operating mode, prevent the condition of stress concentration, realize pressure gradual change in internally mounted inner shell, reduce bladeless fan's vibration amplitude and vibration frequency. The requirement for the heat dissipation capacity of the motor and the bladeless fan under the high-power condition is met by taking the external air compressor as a power source. The fixing mode of the invention has the advantages that the internal space is enlarged, more gas can be gathered and then flows out from the gap, and the fluid speed and the flow rate are improved. The self-contained motor is not used as a power source, and the external air compressor is used as a power source, so that the problems of high requirements on the motor and high heat generation quantity of the device under the condition of high power are solved. The inner shell is arranged in the inner part, so that the pressure can be gradually changed when the internal gas is discharged outwards, the vibration amplitude and the frequency of the internal gas are reduced, and the structure of the bladeless fan is optimized. All the shells are in arc shapes, so that under the impact of high-speed gas, the stress condition is more uniform, and stress concentration cannot occur.
