[0003] The existing compressor exhaust structure consists of an elastic exhaust valve plate and a rigid baffle. One end of the valve plate is fixed to the compressor pump body by screws. During the high-pressure gas discharge process, the exhaust valve plate repeatedly and violently collides between the exhaust baffle and the pump body, which can easily cause fatigue fracture of the exhaust valve plate and noise and vibration problems. Therefore, a compressor exhaust structure is provided. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, referring to Figure 1-4 A compressor exhaust structure includes a connecting cover plate 1, an exhaust structure in the middle of the connecting cover plate 1, a sealing ring 5 fixed at the lower end of the connecting cover plate 1 to ensure the sealing of the connection of the connecting cover plate 1, fixing holes 6 at the four corners of the connecting cover plate 1, a one-way valve assembly for use with the exhaust structure connected to the upper end of the connecting cover plate 1, a fixing cover 2 fixed to the upper end of the connecting cover plate 1, an exhaust pipe 3 at the upper end of the fixing cover 2, the exhaust structure and the one-way valve assembly are both located inside the fixing cover 2, and a sound-absorbing structure is fixed to the inner wall of the fixing cover 2.
[0023] The sound-absorbing structure includes two L-shaped plates 7 fixed to the inner wall of the fixed cover 2, with sound-absorbing cotton 8 inserted between the two L-shaped plates 7, and sound-absorbing holes 10 opened on both L-shaped plates 7.
[0024] The inner walls of the opposite sides of the fixed cover 2 are provided with sound-absorbing structures. There are at least ten sound-absorbing structures, which are evenly distributed on the inner walls of the fixed cover 2.
[0025] The air outlet structure includes a through hole 4 opened in the middle of the connecting cover plate 1, and a pipe 12 is fixed at the upper end of the through hole 4;
[0026] The one-way valve assembly includes a U-shaped plate 9 fixed to the upper end of the connecting cover plate 1, and the U-shaped plate 9 is located outside the pipe 12. A connecting rod 11 is slidably inserted into the horizontal section of the U-shaped plate 9. A T-shaped plug 13 is connected to the lower end of the connecting rod 11. The bottom of the T-shaped plug 13 is engaged with the upper end of the pipe 12. A stop block 14 is connected to the upper end of the connecting rod 11. A spring 15 is sleeved on the part of the connecting rod 11 located between the T-shaped plug 13 and the horizontal section of the U-shaped plate 9.
[0027] Two arc-shaped plates 16 are symmetrically fixed on the outer wall of the pipe 12. The upper ends of the two arc-shaped plates 16 extend above the T-shaped plug 13 and are connected to baffles.
[0028] Working principle: The connecting cover plate 1 is connected to the exhaust end of the compressor through the fixing hole 6 using bolts. When the compressor exhausts, high-pressure gas enters the pipe 12 and pushes the T-shaped plug 13 and the connecting rod 11 upward, which compresses the spring 15. The high-pressure gas enters the fixed cover 2 from the pipe 12 and finally exits from the exhaust pipe 3. When the pressure of the high-pressure gas is insufficient, the rebound action of the spring 15 pushes the T-shaped plug 13 down to seal the upper end of the pipe 12. The structure has good strength and a longer service life. The noise generated by the movement of the T-shaped plug 13 can be absorbed through the sound-absorbing holes 10 of the L-shaped card plate 7 and the sound-absorbing cotton 8, which effectively reduces noise vibration.
[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
