Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides an embodiment:
a motor with good noise reduction effect for air ventilation and purification comprises a shell 1, wherein a vacuum groove 2 is formed in the inner wall of the shell 1, the vacuum groove 2 is vacuum, after working noise of the motor in the shell 1 is transmitted to the inner wall of the shell 1, the vacuum groove 2 is in a vacuum state, and no air is used as a sound wave transmission medium, so that noise sound waves are isolated and weakened, the noise reduction capability of the device is improved, soundproof cotton 3 is paved on the inner wall of the shell 1, the thickness of the soundproof cotton 3 is 2CM, the soundproof cotton 3 is made of fiber porous materials, the motor works and vibrates to generate sound, the sound waves are transmitted to the soundproof cotton 3 through the air in the shell 1, and when passing through the soundproof cotton 3, the sound waves enter numerous fiber holes in the soundproof cotton 3 to be reflected, mutually superposed and collide, so that the sound wave energy can be converted into heat energy, and the sound wave strength;
four groups of first slots 4 are uniformly welded on the inner wall of the right side of the shell 1, first inserting blocks 5 are inserted into the left ends of the first slots 4, a first fixing plate 6 is arranged on the right side inside the shell 1, the left ends of the first inserting blocks 5 are welded and fixed with the first fixing plate 6, a rear cover 8 is arranged on the left side of the shell 1, four groups of second slots 9 are uniformly arranged in the middle of the right side of the rear cover 8, second inserting blocks 10 are inserted into the second slots 9, a second fixing plate 11 is arranged on the left side inside the shell 1, the right ends of the second inserting blocks 10 are welded and fixed with the second fixing plate 11, first springs 7 are sleeved outside the first inserting blocks 5, second springs 12 are sleeved outside the second inserting blocks 10, small-amplitude displacement is generated by motor vibration, the first fixing plate 6 and the second fixing plate 11 support the two sides of the motor through resilience forces of the first springs 7 and the second springs 12, because the first spring 7 and the second spring 12 have good elasticity, the vibration strength of the motor can be greatly reduced, the internal elements of the motor are protected, and the stability of the device is improved, the outer side of the left end of the shell 1 is welded with the fixing ring 13, six groups of screws 14 are uniformly inserted at the edge of the left side of the rear cover 8, the right ends of the screws 14 all penetrate through the rear cover 8 and the fixing ring 13 and extend to the right side of the fixing ring 13, the inner wall of the fixing ring 13 is provided with internal threads, the fixing ring 13 is connected with the screws 14 through a thread structure, a user screws the screws 14 into the screws 14 through the rear cover 8, so that the rear cover 8 is fixed at the left side of the shell 1, four groups of copper plates 15 are uniformly arranged inside the shell 1, four groups of copper bars 16 are uniformly arranged outside the shell 1, two ends of the copper bars 16 all penetrate through the outer wall of the shell 1 and extend into the shell 1, and, the outer sides of the middle parts of the copper strips 16 are uniformly welded with the radiating fins 17, the radiating fins 17 are rectangular sheets, and the multiple groups of radiating fins 17 improve the contact area of the device and air and improve the radiating capacity of the device.
