The utility model belongs to a novel motor amortization structure, including amortization overhead guard, amortization inner tube, direction inner tube and amortization urceolus, amortization overhead guard one end opening, the left end of amortization inner tube is located the amortization overhead guard, the right -hand member of amortization inner tube and the left end intercommunication of direction inner tube, the right -hand member and the amortization urceolus intercommunication of direction inner tube, be fixed with the metal mesh on the left end face of amortization inner tube, the left end of amortization inner tube passes through the bracing piece and fixes the bottom at the amortization overhead guard, the direction inner tube is provided with air suction mouth with the junction of amortization inner tube, and air suction mouth is the loudspeaker form, and air suction mouth's right -hand member opening is greater than the left end. Through amortization overhead guard, amortization inner tube, direction inner tube and amortization urceolus constitution amortization route, it spreads the route to change the ventilation noise many times for the ventilation noise is energy greatly reduced in propagating process, left end through the amortization inner tube lies in the amortization overhead guard, has effectively avoided the problem of the air inlet water of motor edgewise, has realized falling and has solved when making an uproar with waterproof problem.
