Referring to fig. 1 to 4, a flow guide mechanism of a fan includes a flow guide cover 100 and a centrifugal impeller 200 driven by a motor to rotate in the flow guide cover 100, the flow guide cover 100 includes a cover body in a bowl shape, an air inlet 101 is formed in the bottom of the cover body, a side wall 102 of the cover body is in a circular ring shape, a plurality of flow guide portions 110 are uniformly distributed on an inner side surface of the side wall 102, an arc surface 111 is arranged on one side of the flow guide portion 110 close to the centrifugal impeller 200, one end of the arc surface 111 is connected with the inner side surface of the side wall 102, and a boss 112 protruding towards the inside is arranged at the connection. After the motor drives the centrifugal impeller 200 to rotate, the centrifugal impeller 200 extracts air from the air inlet 101 to the inside of the air guide sleeve 100 and pushes the air to the side wall 102 of the air guide sleeve, when the air flows, the air guide part 110 enables the air to flow from one end of the boss 112 on the inner surface of the side wall 102 to one end of the inner surface of the connecting side wall 102 (as shown by an arrow in fig. 4) along the arc surface 111, the air is compressed on the side of the boss 112 of the adjacent air guide part 110, the compressed air flows along the axial direction of the air guide sleeve 100, the air flow in the air guide sleeve 100 is smooth, the obstruction of chaotic air flow to the centrifugal impeller 200 is reduced, the air flow rate of the air inlet 101 entering the air guide sleeve 100 is improved, and noise is reduced.
Furthermore, the arc surface 111, the inner side surface of the side wall 102, and the boss 112 form a compression air duct 120, and the compression air duct 120 extends axially from the bottom of the air guide sleeve 100 along the side wall 102 and is communicated with the air inlet 101. The compressed air flows upward along the compressed air duct 120, so that the air forms a fixed flow path, thereby reducing the turbulence of the air flow in the air guide sleeve 100 and smoothing the air flow in the air guide sleeve 100.
Further, the bottom of the centrifugal impeller 200 faces the air inlet 101, and a plurality of blades 201 radiating outwards are uniformly distributed on the centrifugal impeller 200. By the rotation of the centrifugal impeller 200, air can be drawn into the air guide sleeve 100 from the outside of the air inlet 101, and the air flows towards the side wall 102 of the air guide sleeve 100 through the radial blades 201, so that the effects of stabilizing air flow and reducing noise are achieved.
Further, in order to facilitate installation of the motor, a plurality of installation parts 130 for installing the motor are uniformly distributed on the side part of the air guide sleeve 100, an installation sleeve 300 for fixing the motor is arranged on the air guide sleeve 100, and the installation sleeve 300 is installed on the installation parts 130 through bolts. It can be understood that the body of the motor is embedded and installed, the centrifugal impeller 200 is installed on the rotating shaft of the motor, and the installation cover 300 is installed on the air guide cover 100 through bolts, so that the installation is simple and convenient, and the subsequent maintenance is performed.
Further, in order to facilitate the installation of the air guide sleeve 100 on the air purifier, an installation groove 140 for installing a bolt is opened on the boss 112 on the inner surface of the side wall 102 of the air guide sleeve 100, and a threaded hole is provided at the bottom of the installation groove 140.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
