In order to achieve the above object, the utility model provides an air condition compressor refrigerant muffler, including hollow first hush pipe and second hush pipe and set up the intake pipe of hush hole group, the one end shrink of first hush pipe forms the stiff end, and other end shrink forms the baffle end, the intake pipe stretches into in the first hush pipe and its outer wall with stiff end welded fastening together, the one end shrink of second hush pipe forms the exit end, the other end with first hush pipe welded fastening makes the baffle end be located the inner chamber of second hush pipe.

Preferably, the baffle end is tapered by the contraction of the first silencing pipe, and a plurality of second silencing holes are formed in the side wall of the baffle end.

Preferably, one end of the air inlet pipe extending into the first silencing pipe is closed.

Preferably, a reflecting portion protruding toward the intake pipe is provided at a tip end of the baffle end, and a radius of the baffle end is gradually reduced from the first muffler pipe to the second muffler pipe.

Preferably, the center line of the silencing hole group and the axis of the air inlet pipe are arranged in an inclined mode.

Preferably, the first silencing pipe is positioned above the end of the partition plate and shrinks towards the central axis to form a step, and the second silencing pipe is welded on the step and is connected with the first silencing pipe in a sealing mode.

The utility model has the advantages that: the utility model discloses utilize first hush pipe integrated into one piece baffle end, change the structure that current baffle carries out welded fastening, through making the baffle end be located cavity with first hush pipe and the welding of second hush pipe together, improve the shaping efficiency of product, promoted the noise reduction effect.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.

[ description of the drawings ]

Fig. 1 is a schematic structural diagram of the present invention;

in the figure: 1-a first silencing pipe, 2-a second silencing pipe, 3-a silencing hole group, 4-an air inlet pipe, 5-a baffle end, 6-an outlet end, 7-a second silencing hole, 8-a reflection part and 9-a step.

[ detailed description ] embodiments

Referring to fig. 1, the utility model discloses a hollow first hush pipe 1 and second hush pipe 2 and set up intake pipe 4 of hush hole group 3, the one end shrink of first hush pipe 1 forms the stiff end, and the other end shrink forms baffle end 5, intake pipe 4 stretches into in the first hush pipe 1 and its outer wall with stiff end welded fastening together, the one end shrink of second hush pipe 2 forms exit end 6, the other end with 1 welded fastening of first hush pipe makes baffle end 5 be located the inner chamber of second hush pipe 2. Utilize 1 one end of first hush pipe for being used for the stiff end of fixed intake pipe 4, the other end is baffle end 5, stiff end and

baffle end

5 and 1 integrated into one piece of first hush pipe, change the mode that current baffle needs the production alone, overcome current baffle and need carry out welded fastening's defect, through make the baffle end be located

first hush pipe

1 and 2 formation cavities of second hush pipe with the welding of second muffler on first hush pipe, change among the prior art, need weld the mode at its inner chamber with the baffle before hush pipe shrink processing, make the production shaping of product more convenient, improve product production efficiency.

Specifically, the baffle end 5 is contracted into a conical shape by the first silencing pipe 1, and a plurality of second silencing holes 7 are formed in the side wall of the baffle end 5. The baffle end 5 adopts a conical structural design, and the second silencing holes 7 in the baffle end 5 can diffuse the refrigerant collected by the baffle end 5 to the side wall of the second silencing pipe 2, so that the flowing pressure of the refrigerant is reduced, and the silencing effect is improved.
