[0021] A fan mesh hoop of the utility model is described in conjunction with the accompanying drawings.

[0022] like Figures 1 to 6 The fan mesh hoop shown in the figure comprises an integrated ring body 1. Since the main body of the mesh hoop adopts an integrated ring body 1 structure, the mesh hoop of the present application can be installed and removed without the help of tools; the inner side wall of the ring body 1 is provided with an annular limiting groove 11, and the ring body 1 is provided with a plurality of hollow holes 12 at least on one side of the limiting groove 11. The hollow holes 12 can increase the elasticity of the ring body 1 and make the mesh hoop easier to install and remove with the mesh cover 2; the fan comprises a mesh cover 2, the limiting groove 11 is provided with a plurality of hollow holes 12, and the hollow holes 12 can increase the elasticity of the ring body 1 and make the mesh hoop easier to install and remove with the mesh cover 2; the fan comprises a mesh cover 2, the limiting groove 11 is provided with a plurality of hollow holes 12, and the hollow holes 12 can increase the elasticity of the ring body 1 and make the mesh hoop easier to install and remove with the mesh cover 2; the fan comprises a mesh cover 2, the limiting groove 11 is provided with a plurality of hollow holes 12, and the hollow holes 12 are ... The groove 11 includes a limiting bottom surface 111, a limiting side surface 112 and a limiting bevel block 113. The limiting side surface 112 and the limiting bevel block 113 are arranged on the limiting bottom surface 111, and the limiting side surface 112 and the limiting bevel block 113 are arranged relatively to each other. The edge 23 of the mesh cover 2 slides along the limiting bevel block 113 and is limitedly installed in the limiting groove 11. In this way, when the mesh hoop is installed on the mesh cover 2 of the fan, the mesh cover 2 and the ring body 1 are buckled together so that the edge 23 of the mesh cover 2 slides into the limiting groove 11.

[0023] like Figures 1 to 6 As shown, the mesh cover 2 includes a front mesh cover 21 and a rear mesh cover 22, the edge 23 of the front mesh cover 21 slides into the limiting groove 11 along the limiting bevel 113, and the edge 23 of the rear mesh cover 22 slides into the limiting groove 11 along the limiting bevel 113, and the front mesh cover 21 and the rear mesh cover 22 are relatively arranged in the limiting groove 11, and the limiting groove 11 also includes a spacer block 114, and the spacer block 114 is arranged on the limiting bottom surface 111 between the limiting side surface 112 and the limiting bevel 113. After the edges 23 of the front mesh cover 21 and the rear mesh cover 22 are installed in the limiting groove 11, they are spaced apart by the spacer block 114, and the spacer block 114 can prevent the front mesh cover 21 and the rear mesh cover 22 from colliding with each other and making noise.

[0024] like Figures 1 to 3 As shown, the front mesh cover 21 is the air outlet surface of the fan, the rear mesh cover 22 is the air inlet surface of the fan, and the hollow hole 12 is arranged on the ring body 1 on one side of the front mesh cover 21. The hollow hole 12 also serves as an air duct, which can prevent the ring body 1 from obstructing the air outlet surface.

[0025] like Figure 1 and Figure 2As shown, the hollow holes 12 are evenly arranged in a ring shape along the direction of the limiting groove 11. The evenly arranged hollow holes 12 can make the physical properties of the ring body 1 more excellent. The hollow holes 12 can also serve as air ducts to prevent the mesh hoop from affecting the blowing effect of the fan, and the evenly arranged hollow holes 12 have a better effect as air ducts.

[0026] In addition, the present application provides another implementation of the hollow holes 12 , where the ring body 1 is provided with a plurality of hollow holes 12 on both sides of the limiting groove 11 .

[0027] like Figure 3 and Figure 6 As shown, the surface of the limiting bevel block 113 facing away from the limiting side surface 112 is set as an inclined surface 1131, and the edge 23 of the mesh cover 2 slides into the limiting groove 11 along the inclined surface 1131. The inclined surface 1131 can make the mesh cover 2 and / or the mesh hoop more easily produce elastic deformation, so that the edge 23 of the mesh cover 2 can slide into the limiting groove 11 more easily.

[0028] like Figure 3 and Figure 4 As shown, it also includes a movable limiting member 3, which includes a hinge shaft 31, a buckle 32 and a first limiting block 33. A mounting position 13 is provided on the ring body 1, and one end of the movable limiting member 3 is hingedly installed on the mounting position 13 through the hinge shaft 31, and the other end of the movable limiting member 3 is buckled on the mounting position 13 through the buckle 32, and the first limiting block 33 passes through the mounting position 13 and extends into the mesh cover 2. When the movable limiting member 3 is buckled in the mounting position 13, the first limiting block 33 passes through the mounting position 13 and extends into the mesh cover 2 to form a rotation limit between the ring body 1 and the mesh cover 2, thereby avoiding rotation and other actions between the ring body 1 and the mesh cover 2 to generate noise. The movable limiting member 3 is configured to be rotatable, so that the installation and disassembly of the mesh hoop is more convenient.

[0029] like Figure 3 and Figure 5 As shown, the ring body 1 is also provided with a second limit block 14, and the second limit block 14 extends into the mesh cover 2. The setting position of the second limit block 14 is opposite to the position of the first limit block 33, and cooperates with each other to form a rotation limit between the mesh cover 2 and the ring body 1. The rotation limit formed by the cooperation of the first limit block 33 and the second limit block 14 can make the rotation limit between the ring body 1 and the mesh cover 2 more sufficient.

[0030] like Figure 4 As shown, the first limiting block 33 is further provided with an extending block 331 extending toward the edge 23 of the mesh cover 2 , so that the first limiting block 33 can also be used to limit the edge 23 of the mesh cover 2 .
