DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Refer to Figures 1-4, the exhaust pipe assembly for an air conditioner with a dual-compressor system provided by the present utility model: includes a housing 1, two symmetrically distributed intake pipes 2 are fixedly connected to the top of the housing 1, an outlet pipe 3 is fixedly connected to the center of the top of the housing 1, the intake end of the intake pipe 2 is fixedly installed at the discharge end of the compressor, the outlet end of the intake pipe 2 is fixedly installed at the intake end of the condenser, and an inner cylinder 4 is fixedly installed inside the housing 1; check valves 5 are fixedly installed inside both intake pipes 2, and the check valves 5 are used to prevent gas backflow; a filtering assembly 6 is fixedly installed inside the inner cylinder 4, and the filtering assembly 6 is used to filter impurities in the gas.

[0022] First, install the two intake pipes 2 on the two compressors, then install the outlet pipe 3 on the condenser. Then, during use, the high-pressure and high-temperature gas generated by the compressor enters the intake pipe 2, and then after passing through the check valve 5, it enters the inside of the housing 1. At this time, the impurities in the gas are filtered by the filtering assembly 6. After the filtering is completed, it enters the outlet pipe 3, and finally the gas is transported to the condenser through the outlet pipe 3.

[0023] The check valve 5 includes a first baffle 501, a second baffle 502, a spring 503 and a plug 504. The inner wall of the intake pipe 2 is fixedly connected with the first baffle 501. The second baffle 502 is fixedly connected to the bottom of the first baffle 501 and is movably located inside the intake pipe 2. The spring 503 is fixedly connected to the bottom of the first baffle 501, and the plug 504 is fixedly connected to the bottom of the spring 503.

[0024] When there is no gas passing through, the plug 504 is pushed by the spring 503 to fit on the top of the second baffle 502, so as to achieve the sealing inside the intake pipe 2. When the gas enters from the bottom of the intake pipe 2, the gas pushes the plug 504 to move upward, compressing the spring 503. At this time, the gas can pass through the second baffle 502, the plug 504 and the first baffle 501 in sequence and enter the inside of the housing 1; if there is gas backflow at the top of the intake pipe 2, there will no longer be a thrust at the bottom of the plug 504. At this time, the plug 504 is pushed downward by the elastic force of the spring 503 to fit on the top of the second baffle 502, so as to prevent gas backflow.

[0025] A plurality of air holes 505 are opened inside the plug 504, and the air holes 505 are located on the top of the second baffle 502.

[0026] When the plug 504 moves upward, there is a gap between the plug 504 and the second baffle 502. At this time, the gas can pass through the air holes 505 and pass through the plug 504.

[0027] The filtering component 6 includes a support frame 601, a mounting cylinder 602, a filter net 603, and an activated carbon filter block 604. A plurality of support frames 601 are fixedly connected to the inner wall of the inner cylinder 4. The inner part of the support frame 601 is fixedly connected with a mounting cylinder 602. An activated carbon filter block 604 is fixedly installed inside the mounting cylinder 602. A filter net 603 is fixedly installed between the inner cylinder 4 and the mounting cylinder 602. There is a gap for gas to pass through between the bottom of the mounting cylinder 602 and the inner cylinder 4.

[0028] During use, the gas inlet pipe 2 enters the space between the inner cylinder 4 and the mounting cylinder 602, then moves downward. When passing through the filter net 603, metal debris in the gas is filtered out. Then it continues to move downward, passes through the gap at the bottom of the mounting cylinder 602 and enters the inside of the mounting cylinder 602, and then the activated carbon filter block 604 filters out tiny particles in the gas.

[0029] External threads 101 are provided at the bottom of the outer wall of the outer shell 1, and internal threads 401 corresponding to the external threads 101 are provided at the bottom of the inner wall of the inner cylinder 4.

[0030] During use, the inner cylinder 4 can be fixedly installed inside the outer shell 1 through the external threads 101 and the internal threads 401.

[0031] A plurality of anti-slip grooves 402 are provided on the outer wall of the inner cylinder 4.

[0032] When installing and disassembling the inner cylinder 4, the anti-slip grooves 402 can play an anti-slip role.

[0033] Working principle: First, install the two inlet pipes 2 on two compressors, then install the outlet pipe 3 on the condenser, and then threadedly install the inner cylinder 4 inside the outer shell 1.

[0034] Then, during use, the high-pressure and high-temperature gas generated by the compressor enters the inlet pipe 2. The gas pushes the plug 504 upward, compressing the spring 503. At this time, the gas can sequentially pass through the second baffle 502, the plug 504, and the first baffle 501 and enter the inside of the outer shell 1.

[0035] Then, the gas inlet pipe 2 enters the space between the inner cylinder 4 and the mounting cylinder 602, then moves downward. When passing through the filter net 603, metal debris in the gas is filtered out. Then it continues to move downward, passes through the gap at the bottom of the mounting cylinder 602 and enters the inside of the mounting cylinder 602, and then the activated carbon filter block 604 filters out tiny particles in the gas. Then the gas moves upward and is transported to the condenser through the outlet pipe 3.

[0036] Finally, after use, remove the inner cylinder 4 and clean the impurities inside.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
