[0021] Please refer to Figures 1-6The utility model provides a kind of small general gasoline generator air cleaner, including closure plate 1, upper cover 2, first frame body 3, second frame body 4 and base 5, the upper cover 2 has guide groove 6, the guide groove 6 is provided with the frame 7 of resistance, the upper cover 2 and the one side of the base 5 have side air port 8, the first frame body 3 is provided with filter core 9, the second frame body 4 is provided with filter sponge 10, the base 5 has recess 11, the middle part of the recess 11 is provided with L-shaped baffle 12, the upper of the base 5 has mounting groove 13, the inner side of the mounting groove 13 has fixed groove 14, the upper of the fixed groove 14 is provided with knob bolt 15, the other inner side of the mounting groove 13 has through-hole 16, the end surface of the base 5 has end surface air port 17, the closure plate 1 is slidably connected with the base 5, and is located between the fixed groove 14, mounting groove 13 and through-hole 16, and is just above the first frame body 3 and the second frame body 4, the knob bolt 15 is just above one end of the closure plate 1, the upper cover 2 is fixedly connected with the base 5 by bolt, and is covered on the base 5, the first frame body 3 and the second frame body 4 are slidably arranged between the recess 11, and are just above the L-shaped baffle 12, and are also located between the guide groove 6 and the end surface air port 17, the frame 7 of resistance and the second frame body 4 mutually resist, by the closure plate 1, the upper cover 2, the first frame body 3, the second frame body 4 and the base 5, these components jointly constitute a complete air cleaner structure, can effectively filter the air entering the gasoline generator;The design of the guide groove 6 helps to guide air flow, and ensures that air is filtered through the filter core 9 and the filter sponge 10, and simultaneously, the mutual resistance of the frame 7 of resistance and the second frame body 4 can maintain the stability of structure.
[0022] Among them, the end surface air port 17, the recess 11, the guide groove 6 and the side air port 8 are all in communication state arrangement, through this design, it is ensured that air can smoothly enter from the side air port 8, pass through the guide groove 6, the recess 11, and finally pass through the end surface air port 17 and enter the generator, which helps to improve the filtering efficiency and performance of air cleaner.
[0023] Secondly, the inner bottom of the recess 11 is provided with a plurality of springs 18, the upper of the spring 18 is provided with top sheet 19, and the top sheet 19 and the first frame body 3 and the second frame body 4 mutually resist, and penetrate the L-shaped baffle 12, by the design of the spring 18 and the top sheet 19, the first frame body 3 and the second frame body 4 are provided with thrust, so that when the first frame body 3 and the second frame body 4 are replaced, the first frame body 3 and the second frame body 4 can automatically pop out the recess 11.
[0024] Again, the inner bottom of the guide groove 6 is provided with a guide block 20, and the guide block 20 extends to the side air port 8, and the design of the guide block 20 helps to further guide the air flow, ensuring that the air can accurately enter the filter core 9 and the filter sponge 10, and at the same time, the guide block 20 extends to the side air port 8, which can more effectively utilize the internal space of the air cleaner.
[0025] In addition, the small universal gasoline generator air cleaner further comprises a sealing gasket 21 arranged between the upper cover 2 and the base 5, and a plurality of positioning rods 22 fixedly connected with the base 5 and located at the inner bottom of the groove 11, and the spring 18 is further sleeved on the corresponding positioning rod 22. The sealing gasket 21 ensures the sealing between the upper cover 2 and the base 5, preventing unfiltered air from directly entering the generator, which helps to improve the filtering efficiency and performance of the air cleaner. The design of the positioning rod 22 provides stable support for the spring 18 and ensures the correct position of the first frame 3 and the second frame 4 in the mounting groove 13, which helps to maintain the stability and filtering efficiency of the air cleaner structure.
[0026] When the filter core 9 is replaced using the utility model, the knob bolt 15 is rotated so as not to abut against one end of the closure plate 1, and then the closure plate 1 is slid to be taken out from between the fixing groove 14, the mounting groove 13 and the through hole 16. After the closure plate 1 is removed, it can be seen that the first frame 3 and the second frame 4 abut against the L-shaped partition plate 12. At this time, the two frames can be carefully taken out from the L-shaped partition plate 12 and separated from the position between the guide groove 6 and the end face air port 17. Then, the new first frame 3 and the second frame 4 are prepared and installed in sequence. The new frames are abutted and sent to the L-shaped partition plate 12 and ensured to be correctly located between the guide groove 6 and the end face air port 17. Then, the closure plate 1 is reinstalled in place, and the knob bolt 15 is rotated to fix the closure plate 1. In this way, the technical problem that the filter core and the upper cover 2 are both fixedly installed on the base 5 by a plurality of bolts, so that when the filter core is replaced, the plurality of bolts need to be removed first and then the filter core can be replaced, is solved.
[0027] The above only discloses a preferred embodiment of the utility model, and of course cannot limit the scope of the utility model. Those skilled in the art can understand that all or part of the above-mentioned processes can be implemented, and equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
