Embodiment Construction

[0025] In order to better understand the purpose, structure and function of the present invention, an air supply assembly and a bladeless fan of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1 to Figure 3 As shown, the air supply assembly of the present invention, driven by the centrifugal fan, enters air from the air inlet 11 along the air duct and discharges it from the air outlet 42 .

[0027] Specifically, the air supply assembly includes a volute 1 . The volute 1 is generally cylindrical in shape, and air inlets 11 are formed at both ends of the volute 1 . The volute 1 is provided with a wind wheel 12 as a driver, and the wind wheel 12 is a centrifugal wind wheel 12, so that the wind wheel 12 rotates, sucks air from the air inlet 11, and discharges it to the outside. Generally, the wind wheel 12 is a centrifugal wind wheel 12. By acting on the fluid, the velocity energy and pressur...

Abstract

The invention discloses an air supply assembly and a bladeless fan. The air supply assembly comprises a volute, and a rear air duct arranged in the tangential direction is arranged on the side face of the volute; the end of the rear air duct communicates with the volute, and an air guide wall and a front air duct are respectively arranged on two sides of the end part of the rear air duct; the front air duct is located on the side, away from the volute, of the end of the rear air duct and forms an air outlet; and the air guide wall is located on the side, close to the volute, of the end of the rear air duct so as to guide air sucked by the volute to the air outlet. According to the air supply assembly, the distance between the air outlet and the air guide wall is increased, and the noise of a cavity is reduced; and high-speed air flow enters the rear air duct and hits the air guide wall, and the air flow extruded by a narrow air duct uniformly flows out of the air outlet.

Description

technical field [0001] The invention belongs to the field of air supply, in particular to an air supply assembly and a bladeless fan. Background technique [0002] Bladeless fan is also called air doubling machine, it can generate natural and continuous cool wind, by forcing the air to be discharged through the air outlet of the air duct, thereby increasing the flow of air, because of its safety, cleanliness, beauty and other characteristics, it is popular among consumers favor. [0003] The existing bladeless fan includes a base, the base is connected with an air duct, and a rotatable wind wheel is arranged in the base. When the wind wheel rotates, the air enters from the air inlet on the side of the base, and is discharged from the air outlet of the air duct. Discharge, so as to achieve the effect of "leafless" wind. [0004] However, the high noise and low air volume have always been criticized by users, seriously affecting the user experience. This is due to the exist...
