Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1 to 4, an idle call muffler, including muffler cavity 1, intake pipe 2, outlet duct 3 and anti-shake piece 4, the lower extreme of muffler cavity 1 is sealed setting, and the upper end spinning of muffler cavity 1 has air inlet throat 5, in air inlet throat 5 was arranged in to intake pipe 2, turn-ups hole 6 had been seted up to the side of muffler cavity 1, in turn-ups hole 6 was arranged in to outlet duct 3, the flaring end of outlet duct 3 was put in the muffler outside, the one end of anti-shake piece 4 sets up in the other end of outlet duct 3, and the other end butt of anti-shake piece 4 is on the lateral wall of intake pipe 2, in the inside diameter of muffler cavity 1 on the outlet duct 3 to the air vent 7 of seting up a plurality of equipartition, be provided with spacing bump 8 in the outside of muffler cavity 1 on the outlet duct 3.
In the present embodiment, the lower port of the intake pipe 2 is lower than the level of the burring hole 6.
In this embodiment, the lower end of the muffler cavity 1 is bottomed by spinning.
In this embodiment, the limit protrusions 8 are abutted to the outward flanges of the flanged holes 6, and the number of the limit protrusions is even.
It is worth noting that anti-shake piece 4 is solid construction, and the one end of anti-shake piece 4, which is far away from air inlet pipe 2, is set up as the boss, and matches with the inner wall of air outlet pipe 3.
Further, the diameter of the anti-shake member 4 is not larger than the diameter of the burring hole 6.
The working process and principle are as follows: in the use process of the utility model, firstly, the refrigerant enters the muffler cavity 1 through the air inlet pipe 2, because the lower end of the air inlet pipe 2 extends into the silencer cavity 1 for a long time and is lower than the height of the flanging hole 6, the air-cooling medium can be fed for enough buffering time, the air inlet pipe 2 can be stably and does not vibrate under the abutting of the anti-vibration piece 4, after buffering and silencing, the refrigerant is discharged from the vent hole 7 through the air outlet pipe 3, the diameter of the anti-shake part 4 is not more than that of the flanging hole 6, and the limit salient point 8 on the air outlet pipe 3 is arranged, can ensure that the process of welding the air outlet pipe 3 to the flanging hole 6 can be smoothly realized, and when the limit salient point 8 is butted against the side end of the flanging hole 6, anti-shake 4 just butts with the lateral wall of intake pipe 2, can not produce invalid clearance, has avoided simultaneously because put into too deeply, leads to intake pipe 2 to take place bending deformation.
Based on the above, the anti-shake device 4 is arranged to abut against the outer wall of the air inlet pipe 2, so that the air inlet pipe 2 with a longer pipe body embedding part tends to be stable, and even if the flow velocity of the refrigerant is higher, resonance with the air inlet pipe 2 is avoided, and secondary noise is avoided; through the lower extreme spinning at muffler cavity 1 and seal to set up flanging hole 6 by the side of muffler cavity 1, the refrigerant is through the inside amortization back of cavity, discharges from outlet duct 3 through air vent 7, forms the route that can effectively reduce the noise, has cancelled the installation setting of apron structure, greatly reduced manufacturing cost.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
