DETAILED DESCRIPTION

[0023] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in connection with the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0024] Referring to Figs. 1-3 The air compressor energy-saving air inlet device is characterized in that the device body 1 is provided with an air inlet pipe 2, the air inlet pipe 2 is fixedly provided with an outer shell 3, the inner top and the inner bottom of the outer shell 3 are fixedly connected with a positioning block 11, the side of the positioning block 11 away from the air inlet pipe 2 is provided with a filter screen plate 20, the outer shell 3 is provided with an adjusting mechanism, the adjusting mechanism comprises a first guide rod 9 fixedly installed between the inner walls of the two sides of the outer shell 3, a bidirectional threaded rod 8 rotationally connected between the inner walls of the two sides of the outer shell 3, two symmetrical adjusting blocks 10 threadedly sleeved on the bidirectional threaded rod 8, and the end of the bidirectional threaded rod 8 penetrating through the outer shell 3 and fixedly provided with a second hand wheel 7 outside the outer shell 3, and the two adjusting blocks 10 are slidably sleeved on the first guide rod 9.

[0025] The outer shell 3 is provided with two symmetrical installation mechanisms, the installation mechanism comprises an installation box 4 fixedly installed on the outer wall of the outer shell 3, a unidirectional threaded rod 6 threadedly connected and penetratingly arranged on one side of the outer wall of the installation box 4, an upper pressing block 16 rotationally connected to the end of the unidirectional threaded rod 6 in the installation box 4, one end of a spring 18 fixedly connected to the outer wall of the outer shell 3, the other end of the spring 18 fixedly connected with a lower pressing block 17 abutting against the upper pressing block 16, an insertion rod 13 fixedly installed on the side wall of the lower pressing block 17 away from the upper pressing block 16, a through hole 19 formed in the outer wall of the outer shell 3, an installation hole 12 formed in the side wall of the filter screen plate 20, a second guide rod 14 fixedly connected between the inner walls of the two sides of the installation box 4, a sliding block 15 slidably sleeved on the second guide rod 14, the sliding block 15 fixedly connected with the upper pressing block 16, the vertical sections of the upper pressing block 16 and the lower pressing block 17 are all right-angled trapezoidal, the insertion rod 13 is matched with the through hole 19 and the installation hole 12, the insertion rod 13 is square, and the end of the unidirectional threaded rod 6 outside the installation box 4 is fixedly provided with a first hand wheel 5.

[0026] The air compressor comprises the above energy-saving air inlet device.

[0027] In use, the filter plate 20 is positioned inside the outer casing 3 and abuts against the positioning block 11, thereby aligning the mounting hole 12 with the through hole 19. Then, rotating the first handwheel 5 causes the one-way threaded rod 6 to rotate forward. Since the one-way threaded rod 6 is rotatably connected to the upper pressure block 16, and is guided by the second guide rod 14 and the sliding block 15, the upper pressure block 16 can move horizontally forward. During this horizontal forward movement, the inclined surface on the upper pressure block 16 engages with the inclined surface on the lower pressure block 17, allowing the lower pressure block 17 to move horizontally forward. The insertion rod 13 moves towards the filter plate 20, and the spring 18 is compressed, allowing the insertion rod 13 to be inserted into the mounting hole 12 for positioning and fixation. By setting the filter plate 20, the incoming gas can be filtered. By rotating the one-way threaded rod 6 in the opposite direction, the upper pressure block 16 can move horizontally backward. The elastic force generated by the compression of the spring 18 can move the insertion rod 13 away from the mounting hole 12, thereby enabling the filter plate 20 to be disassembled for easy maintenance and replacement, thus reducing energy loss caused by the clogging of the filter plate 20, which is energy-saving and environmentally friendly.

[0028] Rotating the second handwheel 7 allows the bidirectional threaded rod 8 to rotate. The first guide rod 9 guides the adjusting block 10, enabling the two adjusting blocks 10 to move closer or further apart. By moving the two adjusting blocks 10 closer or further apart, one end of the air intake pipe 2 can be blocked, thereby adjusting the air intake area. This meets the usage requirements under different conditions and allows the gas flow rate to be adjusted according to actual needs, avoiding unnecessary energy consumption.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
