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. 2 to 4, in an embodiment of the present invention, an air suction muffler for a mobile refrigeration compressor at least includes a lower chamber 100, an upper cover 200 and a duct 300, the upper cover 200 is disposed on the top of the lower chamber 100, the upper cover 200 is disposed with two air inlet pipes 210 and an air suction pipe 220 corresponding to each other, a sound-deadening chamber 110 is disposed inside the lower chamber 100, sound-deadening chamber partition slots 111 are disposed on the upper cover 200 and the lower chamber 100, a cross sound-deadening chamber partition 112 is disposed between the two sound-deadening chamber partition slots 111, the sound-deadening chamber partition 112 divides the sound-deadening chamber 110 into four sub sound-deadening chambers 113 with different sizes, a U-shaped duct 300 is disposed on the sound-deadening chamber partition 112, the duct 300 at least includes a sub-duct a310 and a sub-duct B320 that are spliced with each other, an air suction end of the duct 300 is communicated with the air, the inlet end of the flow guide pipe 300 and the inlet pipe 210 are arranged in the same sub-silencing cavity 113 in a staggered manner, the bottom surface of the lower cavity 100 is provided with an oil dripping hole 120 which penetrates through the lower cavity 100 and the outside, and the outer side of the lower cavity 100 is provided with an oil dripping hole 130 communicated with the oil dripping hole 120.
