DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. The described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0040] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0041] Embodiment 1

[0042] Reference Figures 2 to 4The pump structure provided by the embodiment comprises a first support 1 and a first muffler 2. The first support 1 comprises a first plate body 11. The edge of the first plate body 11 extends in a direction away from the first plate body 11 to form a groove 12. The first muffler 2 comprises a second plate body 21. The middle part of the second plate body 21 is recessed in a direction away from the second plate body 21 to form a cover body 22. The edge of the first plate body 11 is connected with the edge of the second plate body 21. The groove 12 and the cover body 22 form a flow-through cavity 3 therebetween.

[0043] It can be understood that the edge of the first plate body 11 extends towards the second plate body 21, so that the first support 1 is formed with the groove 12. The groove 12 and the cover body 22 form the flow-through cavity 3, which increases the space between the first support 1 and the first muffler 2, thereby effectively increasing the minimum flow-through area between the first support 1 and the first muffler 2. Without changing the height of the pump structure, the space utilization of the pump structure is effectively improved. The increase of the minimum flow-through area between the first support 1 and the first muffler 2 reduces the resistance when the fluid flows. On the one hand, the flow loss of the fluid is reduced, the energy consumption is reduced, and the suction performance of the compressor is improved, thereby improving the energy efficiency of the compressor. On the other hand, the airflow noise and the pulse pressure are reduced, the sound attenuation effect is enhanced, and the noise generated by the compressor is reduced.

[0044] In the embodiment, the second plate body 21 is circular, the cover body 22 is flower-shaped, and the minimum cross section of the flow-through cavity 3 is L-shaped. It can be understood that the formation of the groove 12 makes the flow-through cavity 3 have a partial transverse spatial extension, thereby increasing the area of the minimum cross section of the flow-through cavity 3, and thereby increasing the minimum flow-through area of the fluid, which is more conducive to improving the energy efficiency of the compressor and reducing the noise.

[0045] The pump structure of the embodiment increases the minimum flow-through area between the first support and the first muffler by providing the groove. Without changing the height of the pump structure, the space utilization of the pump structure is effectively improved, the flow loss is reduced, the energy consumption is reduced, the energy efficiency of the compressor is improved, and the sound attenuation effect is enhanced. Since the minimum cross section of the flow-through cavity is L-shaped, the flow-through cavity has a partial transverse spatial extension, the area of the minimum cross section of the flow-through cavity is increased, and thereby the minimum flow-through area of the fluid is increased, which is conducive to improving the energy efficiency of the compressor and reducing the noise.

[0046] Embodiment 2

[0047] As a further optimization of embodiment 1, reference is made to Figures 5 to 7 The groove 12 is provided with a first through hole 121 and a second through hole 122. The first through hole 121 and the second through hole 122 are respectively located on the two sides of the axis of the first plate body 11. The first through hole 121 is used for allowing the fluid to enter the flow-through cavity 3. The second through hole 122 is used for allowing the fluid to flow out of the flow-through cavity 3.

[0048] In some embodiments, the first through hole 121 has a larger aperture than the second through hole 122. Since the fluid flowing into the flow cavity 3 is compressed fluid, the fluid will flow into the first through hole 121 under pressure. The large aperture of the first through hole 121 is more conducive to the passage of fluid, thereby improving the smoothness of fluid flow.

[0049] As a further optimization, the first guide piece 123 is arranged in the groove 12. One end of the first guide piece 123 is fixedly connected to the inner wall of the groove 12, and the other end is in a suspended state and covers the first through hole 121. It should be noted that one end of the first guide piece 123 covering the first through hole 121 is in a curved state. The first guide piece 123 covers the first through hole 121 but does not close the first through hole 121. The arrangement of the first guide piece 123 can ensure that the fluid flows smoothly into the flow cavity 3 and prevent the fluid in the flow cavity 3 from flowing back from the first through hole 121, thereby improving the stability of the compressor operation.

[0050] In some embodiments, the pump structure further comprises a first fastener 4. The edge of the first plate body 11 is provided with a third through hole 111, and the edge of the second plate body 21 is provided with a fourth through hole 211 corresponding to the position of the third through hole 111. The first fastener 4 is arranged in the third through hole 111 and the fourth through hole 211. In this embodiment, the first fastener 4 is a screw. The connection of the first fastener 4 makes the edge of the first plate body 11 tightly fit with the edge of the second plate body 21, thereby improving the air tightness of the flow cavity 3, preventing the loss of fluid, and further improving the energy efficiency of the compressor.

[0051] Embodiment 3

[0052] Reference Figures 8 to 13 The compressor pump provided in this embodiment comprises a cylinder assembly 100, a rotating shaft 200, a second support 300, a second muffler 400, and the pump structure 500 of Embodiment 1 or 2. The pump structure 500, the cylinder assembly 100, the second support 300, and the second muffler 400 are sequentially arranged on the rotating shaft 200 from bottom to top. The rotating shaft 200 is provided with an eccentric structure corresponding to the position of the cylinder assembly 100. The cylinder assembly 100 comprises a cylinder, a ring, and a blade. The ring is arranged on the eccentric structure of the rotating shaft 200, and the blade is arranged on the cylinder and abuts against the ring. In some embodiments, the second support 300 can also be provided with the same groove 12 as the first support 1 to further improve the energy efficiency of the compressor.

[0053] The cylinder body of the cylinder assembly 100 is formed with a compression cavity 101 and a flow passage 102, the flow passage 102 is located at one side of the compression cavity 101, the compression cavity 101 is communicated with the flow cavity 3 through a first through hole 121, and the flow passage 102 is communicated with the flow cavity 3 through a second through hole 122. The second sound insulation cover 400 is provided with an air inlet 401 and an air outlet 402, and the second support 300 is provided with a fifth through hole 301 and a sixth through hole 302, the fifth through hole 301 corresponds to the position of the compression cavity 101, and the sixth through hole 302 corresponds to the position of the flow passage 102.

[0054] It can be understood that the fluid enters the compressor pump from the air inlet 401, enters the flow cavity 3 after being compressed in the compression cavity 101, and then passes through the flow passage 102 and is discharged from the air outlet 402. By arranging the flow passage 102, the path of the fluid discharged from the compressor pump can be lengthened, the sound insulation effect can be enhanced, and the noise generated by the compressor can be further reduced.

[0055] In some embodiments, the flow passage 102 can be multiple, and the number of the second through hole 122 and the sixth through hole 302 matches the number of the flow passage 102. In this embodiment, the number of the flow passage 102 is two, which can play a role in dispersing the fluid and further enhance the sound insulation effect.

[0056] As a further optimization, the second support 300 is provided with a second guide piece 303, and the end of the second guide piece 303 covers the fifth through hole 301. In this embodiment, the structure and arrangement of the second guide piece 303 are the same as those of the first guide piece 123, and will not be repeated here. By arranging the second guide piece 303, the fluid can smoothly enter the compression cavity 101, and at the same time, the fluid in the compression cavity 101 is prevented from flowing out of the fifth through hole 301, which plays a role in preventing backflow and is beneficial to improve the energy efficiency of the compressor.

[0057] In some embodiments, the compressor pump further comprises a second fastener 600, and the second support 300 and the second sound insulation cover 400 are connected and fixed by the second fastener 600. In this embodiment, the second fastener 600 is a screw. The locking effect of the second fastener 600 can make the connection of the second support 300 and the second sound insulation cover 400 more closely, thereby improving the overall air tightness of the compressor pump, preventing fluid loss during compression, and thus being beneficial to improve the energy efficiency of the compressor.

[0058] In some embodiments, the first sleeve body 112 is formed at the axial position of the first plate body 11, and the second sleeve body 304 is formed at the axial position of the second support 300, and the first sleeve body 112 and the second sleeve body 304 are sleeved on the rotating shaft 200.

[0059] The compressor pump of the embodiment reduces the resistance of fluid flow in the compressor pump by setting the pump structure, reduces flow loss, thereby reduces energy consumption, effectively improves the energy efficiency of the compressor, and further enhances the sound attenuation effect of the first sound attenuation cover, effectively reduces the noise generated by the compressor pump.
