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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a amortization cam rotor pump, which comprises a housin 1, two cams 2 and motor 3, motor 3's the outside is equipped with sound-proof housing 4, sound-proof housing 4 and 1 fixed connection of casing, and the interior table wall fixedly connected with amortization layer 5 of sound-proof housing 4, amortization layer 5 is formed by the concatenation of a plurality of acoustical panels 6, the bloop 7 of a plurality of loudspeaker forms is seted up on acoustical panel 6's surface, the noise is through the design of bloop 7 and reflect at its inside repetition in broadcasting, and then consume a large amount of energy, thereby the energy of sound wave has been reduced, thereby the effect of amortization has been played.

Specifically, as shown in fig. 2, two driving gears 9 are rotatably connected to a side end surface of the housing 1, one of the two driving gears 9 is in transmission connection with an output shaft of the motor 3, the two driving gears 9 are in meshing connection and are respectively fixedly connected with the two cams 2, and the motor 3 drives the driving gears 9 to drive the cams 2 to rotate.

Specifically, as shown in fig. 1, protective layers 8 are laid on the outer surface walls of the two cams 2 and the inner surface wall of the shell 1, the protective layers 8 are made of rubber, the shell 1 and the protective layers 8 of the cams 2 can be attached to each other and are in sliding connection, a feed port 10 and a discharge port 11 are respectively arranged on two sides of the shell 1, and the protective layers 8 are beneficial to reducing collision noise of materials.

Specifically, as shown in fig. 3, the sound-absorbing plate 6 is made of a foam material, and the foam material has a good cushioning effect, and can absorb most of sound waves in a vibration manner, so as to further play a role in sound attenuation.
