In the figure: 1. a housing; 2. reinforcing ribs; 3. a sleeve; 4. a blade; 5. reinforcing edges; 6. reinforcing ribs; 7. a cavity.
Detailed Description
The present utility model will be described in detail below with reference to the accompanying drawings and examples.
Examples: the utility model provides a fan of stable operation, as shown in fig. 1, fig. 2, including housing 1, pivot and with pivot fixed connection's impeller, the impeller includes sleeve 3 and with sleeve 3 fixed connection's blade 4, housing 1 includes air outlet and air intake, the edge fixedly connected with reinforcing bead 5 that blade 4 is close to air outlet one side, fixedly connected with strengthening rib 6 on the blade face of blade 4, the one end and the reinforcing bead 5 fixed connection of strengthening bead 6, the other end of strengthening rib 6 extends to the edge that blade 4 is close to air intake one side.
Specifically, five blades 4 are integrally formed on the impeller, the blades 4 are arranged on the outer circumferential array of the impeller, a reinforcing edge 5 and five reinforcing ribs 6 are integrally formed on each blade 4, the length of each reinforcing edge 5 is identical to the length of the edge of each blade 4 close to the air outlet, the cross section of each reinforcing edge 5 is circular, the cross section of each reinforcing rib 6 is square, the strength of the edge of each blade 4 is improved by the reinforcing edge 5, the strength of the blade surfaces of the blades 4 is improved by the reinforcing ribs 6, meanwhile, the reinforcing ribs 6 also transmit the force born by part of the blade surfaces of the blades 4 to the reinforcing edges 5, and the reinforcing edges 5 bear torsion force, so that the load born by the blade surfaces of the blades 4 is reduced, the deformation of the blades 4 is avoided, and the stability of a fan is improved.
As shown in fig. 1 and 2, the reinforcing ribs 6 are positioned on the surface of the blade 4 near the air inlet, the reinforcing ribs 6 are perpendicular to the reinforcing edge 5, and the density of the reinforcing ribs 6 is smaller as the reinforcing ribs are closer to the sleeve 3.
Specifically, the stiffener 6 carries out the gradual change array of route along stiffener 5, the more is from sleeve 3, the interval between the stiffener 6 is less, stiffener 6 is concentrated at the terminal that sleeve 3 was kept away from to blade 4, the terminal intensity of blade 4 has been guaranteed, because the air-out direction of fan is from the air intake to the air outlet, so the atress direction of blade 4 is from the air outlet to the air intake, set up stiffener 6 on the blade face that blade 4 is close to the air intake, when blade 4 has the deformation trend, stiffener 6 receives the extrusion and hinder blade 4 deformation, stiffener 6 perpendicular to stiffener 5 has reduced stiffener 6's windward area, the windage of stiffener 6 has been reduced, the energy efficiency loss of fan has been reduced promptly.
As shown in fig. 1 and 2, the thickness of the side, close to the sleeve 3, of the blade 4 is greater than the thickness of the side, away from the sleeve 3, of the blade 4, a cavity 7 is formed in each blade 4, two side walls of the cavity 7 arch outwards, and reinforcing ribs 2 are fixedly connected between the two side walls of the cavity 7.
