[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-4 The present invention provides a technical solution: an intake and exhaust buffer structure for a compressor, including a buffer tank 1, on which two air guides 3 are provided, the two air guides 3 are symmetrically arranged, and a connecting component 2 is connected to one of the non-adjacent ends of the two air guides 3, the two connecting components 2 are symmetrically arranged.

[0029] The buffer tank 1 includes two symmetrically arranged conical portions 102, with a middle portion 101 connecting the two conical portions 102. The ends of the two conical portions 102 away from the middle portion 101 are respectively connected to end portions 103. The small end of the conical portion 102 is connected to the middle portion 101, and the large end of the conical portion 102 is connected to the end portion 103. Meanwhile, the first conical portion 102 has a conical cylindrical structure, the middle portion 101 has a cylindrical structure, and the conical portion 102 and the middle portion 101 are coaxial.

[0030] The air guide 3 is composed of a straight cylindrical part 301 and a conical part 302. The straight cylindrical part 301 and the conical part 302 are coaxial. The conical part 302 is located inside the conical part 102 and is coaxial with the conical part 102. The large end of the conical part 302 is connected to the straight cylindrical part 301. The straight cylindrical part 301 passes through the end 103 and is fixedly connected to the end 103. Specifically, the end 103 is provided with a hole that is adapted to the straight cylindrical part 301.

[0031] In addition, multiple openings 303 are provided at the joint between the straight cylindrical part 301 and the conical part 302, and the multiple openings 303 are evenly distributed around the axis of the straight cylindrical part 301.

[0032] The connecting assembly 2 includes a connecting ring 201, which is fixedly sleeved on the outside of the straight cylindrical part 301, and a connecting flange 202 is fixed at one end of the connecting ring 201.

[0033] In this embodiment, the compressor's inlet or outlet can be connected via a connecting flange 202. When connecting the compressor's inlet, the airflow passes through another connecting component 2 and enters the corresponding conical section 302. Since the conical section 302 is tapered, the airflow impacts the inner wall of the conical section 302, which facilitates changing the airflow direction and reduces gas impact. At the same time, a portion of the airflow is discharged through the opening 303 on the conical section 302. This portion of gas impacts the inner wall of the corresponding conical section 102, which also has a buffering effect on the gas discharged through the opening 303. In addition, a portion is directly discharged into the buffer tank 1 through the end of the conical section 102 away from the straight section 301. Since there are two air guides 3, which are symmetrically arranged, and the left and right parts of the entire buffer tank 1 are symmetrically arranged, the airflow can be dispersed through the above arrangement, which facilitates the airflow to change its flow direction multiple times, thereby reducing airflow pulsation, stabilizing the airflow entering the compressor, and helping to improve the compressor's suction efficiency.

[0034] Similarly, when the compressor exhaust port is connected through a connecting flange 202, the pressure impact on the downstream equipment connected to the other connecting flange 202 can be reduced.

[0035] Example 2

[0036] Please see Figure 2 and Figure 5 This embodiment, based on Embodiment 1, further includes two support blocks 4, which are symmetrically arranged and fixed to the inner walls of the two end portions 103 respectively. Each support block 4 is fixedly connected to a conical spiral rod 5, which is symmetrically arranged and sleeved on the outside of the two conical cylinder portions 302. Each conical spiral rod 5 is fixedly provided with a matching spiral plate 6, which has multiple second through holes 601 evenly distributed on it. At the same time, the small ends of the two conical spiral rods 5 are close to each other, and the large ends of the two conical spiral rods 5 are close to the two end portions 103 respectively. The two spiral plates 6 are sleeved on the outside of the two conical cylinder portions 302 respectively.

[0037] In this embodiment, by adding a spiral plate 6 to the outside of the cone section 302, when the airflow flows through the first cone section 302, the airflow discharged from the corresponding opening 303 of the cone section 302 passes through the spiral plate 6 outside the cone section 102. Since the spiral plate 6 has a spiral structure and multiple second through holes 601 are evenly distributed on the spiral plate 6, the spiral plate 6 has a dispersing effect on the airflow. Since there are two spiral plates 6, when the airflow flows through the spiral plate 6, it can have a dispersing effect on the airflow, which can further reduce the airflow pulsation in the buffer tank 1 and improve the stability of the airflow discharged by the buffer structure.

[0038] Example 3

[0039] Please see Figure 2 , Figure 5 , Figure 6 as well as Figure 7 Based on Embodiment 2, this embodiment further includes two support rings 8, which are fixed to the inner walls of the two conical portions 102 respectively. Each of the two support rings 8 is provided with a conical sleeve 7. The two conical sleeves 7 are respectively sleeved on the outside of the two conical portions 302. The conical sleeves 7 are coaxial with the conical portions 302, and the portions of the conical portions 302 corresponding to the conical sleeves 7 are evenly distributed with a plurality of first through holes 304. Each conical sleeve 7 is sleeved on the outside of a portion of the corresponding conical spiral rod 5, and the conical sleeve 7 does not contact the conical spiral rod 5.

[0040] In this embodiment, two conical sleeves 7 are symmetrically arranged. By setting the conical sleeves 7 and providing multiple first through holes 304 on the conical part 302, the dispersion effect of the airflow in the buffer tank 1 is further improved, making the airflow discharged from the buffer structure more stable.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
