DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0027] Embodiment 1: Refer to Figs. 1-3 An air compressor with self-adaptive air intake volume is applied in the technical field of air compressors, which comprises an air compressor body 1 and an air inlet pipe 2 fixed in the air compressor body 1. The design of the air inlet pipe 2 aims to optimize the process of air entering the compressor body and ensure the controllability of air quality and air intake volume.

[0028] An connecting cylinder 13 is arranged inside the air inlet pipe 2, and the surface of the connecting cylinder 13 is distributed with a plurality of filter holes 14. These filter holes 14 are used to preliminarily filter the entering air to remove impurities and particulate matter, so as to protect the precision components inside the compressor.

[0029] In order to stably fix the connecting cylinder 13 in the air inlet pipe 2, a set of extrusion assemblies is designed. The set of assemblies comprises a connecting ring 7 which is threadedly connected with the surface of the air inlet pipe 2 through external threads. An extrusion ring 8 is fixed to the inner wall of the connecting ring 7. When the connecting ring 7 is tightened, the extrusion ring 8 tightly extrudes the side ring of the connecting cylinder 13, thereby achieving fixation.

[0030] In order to ensure the accuracy of the connecting cylinder 13 during installation, a positioning assembly is also designed. The assembly includes a matching slot 10 opened in the side end of the air inlet pipe 2, and a side ring and four positioning blocks 11 on the connecting cylinder 13. The four positioning blocks 11 are fixed in the matching slot 10, and the side ring is provided with four matching positioning slots 12. During installation, the positioning blocks 11 will slide into the positioning slots 12 to provide accurate guidance and positioning for the connecting cylinder 13.

[0031] In order to adjust the air intake of the air inlet pipe 2, an adjusting assembly is designed, which includes a micro ball valve 6 fixedly installed in the air inlet pipe 2. By adjusting the opening of the micro ball valve 6, the air amount entering the compressor body can be accurately controlled, thereby realizing the function of self-adaptive air intake.

[0032] In order to facilitate the operation of the connecting ring 7, a screw ring 9 is also fixed on the surface to increase the torque during operation, making the tightening and loosening process more easy.

[0033] In order to further enhance the stability of the connecting cylinder 13, a pull rod 15 is also fixed inside the connecting cylinder 13, which can further prevent the connecting cylinder 13 from deforming or displacing when subjected to pressure.

[0034] Example 2: Reference Figs. 1-3 On the basis of example 1, improvements are made: in order to facilitate the movement of the air compressor, the lower side of the air compressor body 1 is fixed with a fixed frame 3, and the both ends of the fixed frame 3 are rotatably provided with moving wheels 4. In addition, in order to provide stable support when not moving, the lower side of the air compressor body 1 is also fixed with two placing frames 5.

[0035] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
