[0065] The present application provides an air intake structure and a compressor.

[0066] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0067] like Figure 1-Figure 10 As shown, an embodiment of the present application provides an air intake structure, which includes a volute 1, and the volute 1 includes an air inlet 11. A first installation area 12 is reserved on the circumferential surface of the volute 1 near the air inlet 11. The first installation area 12 can be processed or not processed to adapt to the installation of the guide vane adjustment component 3 or not to the installation of the guide vane adjustment component 3.

[0068] Please refer to the attached Figure 1-4 9. When the air intake structure needs to be used for a compressor without an IGV configuration, it is chosen not to process the first installation area 12; the air intake sealing can be ensured by directly using the volute 1.

[0069] Please refer to the attached Figure 5-8 10. When the air intake structure needs to be used for a compressor with an IGV configuration, the first installation area 12 is selected to be processed so as to form the first installation area 12 with structures such as various installation holes that can adaptably assemble the guide vane adjustment assembly 3.

[0070] It should be noted that the angle of the guide vane of the guide vane adjustment assembly 3, that is, the opening, can be adjusted, so that the air flow rate flowing into the intake structure can be adjusted by adjusting the angle of the guide vane.

[0071] As described above, the same set of volute molds can be used to produce compressors with IGV configurations as well as compressors without IGV configurations. Specifically, the volute 1 of the present application takes into account the structural commonalities and differences between compressors with IGV configurations and compressors without IGV configurations, and reserves a specific processing area, namely the first installation area 12, so that during the processing, different processing parameters, tool paths, or adding / omitting specific processing steps can be selected to meet the manufacturing requirements of the volutes for compressors with IGV configurations and compressors without IGV configurations, respectively. Through the optimized design of the volute 1 structure, compressors with IGV configurations and compressors without IGV configurations can share a set of volute molds, which not only maximizes the utilization of resources and reduces mold costs, but also significantly shortens the production cycle, and improves the flexibility of the production line and the ability to respond to market changes.
