Moreover, the filter replacement operation is cumbersome and usually needs to be done by professionals. This not only increases the difficulty of daily maintenance of the equipment, but also significantly increases the time and labor costs of maintenance. Therefore, it is necessary to improve them.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6As shown, this utility model provides an air generator with a filter structure, including a mounting box 1. An air generator body 2 is fixedly connected to the top of the mounting box 1. A first filter chamber 3 and a second filter chamber 4 are fixedly installed inside the air generator body 2. A protective shell 5 is fixedly connected to the back of the mounting box 1. A drive motor 6 is fixedly connected to the outside of the protective shell 5. A lead screw 7 is fixedly sleeved at the other end of the output shaft of the drive motor 6. The other end of the lead screw 7 passes through the protective shell 5 and extends into the interior of the protective shell 5, with a toothed plate 8 threaded onto its outer surface. A gear 9 is meshed with the bottom of the toothed plate 8. The toothed plate 8 and the gear 9 are connected to each other. All surfaces are movably connected to the back of the mounting box 1. A movable shaft 10 is fixedly sleeved on the inner surface of the gear 9. One end of the movable shaft 10 passes through the mounting box 1 and extends into the interior of the mounting box 1, and a rotating rod 11 is fixedly sleeved thereon. A round shaft 12 is fixedly sleeved inside the other end of the rotating rod 11. A lifting plate 13 is movably connected to the outer surface of the round shaft 12. A piston rod 14 is fixedly connected to the top of the lifting plate 13. There are two piston rods 14. The tops of the two piston rods 14 pass through the first filter chamber 3 and the second filter chamber 4 respectively and extend into the interior of the first filter chamber 3 and the second filter chamber 4, and a piston head 15 is fixedly connected thereon.

[0018] When the drive motor 6 is running, the lead screw 7 will rotate, causing the gear plate 8 to move horizontally. This causes the gear plate 8 to mesh with the gear 9, which in turn causes the gear 9 and the rotating rod 11 to rotate around the movable shaft 10. This causes the round shaft 12 to rotate, causing the lifting plate 13 to move upward. This, in turn, causes the two piston rods 14 and the two piston heads 15 to move upward, pushing the filter elements inside the first filter chamber 3 and the second filter chamber 4 to the outside, thus facilitating replacement. The first filter chamber 3 and the second filter chamber 4 are filled with activated carbon and color-changing silica gel, respectively. The activated carbon adsorbs impurities such as oil stains in the air, while the color-changing silica gel adsorbs moisture in the air.

[0019] Among them, the bottom of the inner cavity of the mounting box 1 is fixedly connected with a limiting rod 16. There are two limiting rods 16. The top of the two limiting rods 16 is fixedly connected to the bottom of the mounting box 1, and the outer surface of the two limiting rods 16 is movably sleeved with the inner surface of the lifting plate 13.

[0020] The design of the two limit rods 16 serves to limit the lifting plate 13, ensuring the stability of the lifting movement of the lifting plate 13.

[0021] Among them, the back of the mounting box 1 is fixedly connected to the limiting block 17, and the outer surface of the limiting block 17 is movably connected to the inner surface of the toothed plate 8.

[0022] The design of the limit block 17 serves to limit the movement of the toothed plate 8, ensuring the stability of the horizontal movement of the toothed plate 8.

[0023] Among them, a support frame 18 is movably sleeved on the outer surface of the movable shaft 10, the bottom of the support frame 18 is fixedly connected to the bottom of the inner cavity of the mounting box 1, and a sealing ring 19 is movably installed on the outer surface of the piston head 15.

[0024] The support frame 18 is designed to support the movable shaft 10, and the sealing ring 19 is designed to ensure the airtightness of the first filter chamber 3 and the second filter chamber 4.

[0025] The first filter chamber 3 is fixedly connected to an air inlet pipe 20, which penetrates the air generator body 2 and extends to the outside of the air generator body 2. A connecting pipe 21 is fixedly connected between the first filter chamber 3 and the second filter chamber 4. An exhaust pipe 22 is fixedly connected to the outer surface of the second filter chamber 4, which penetrates the air generator body 2 and extends to the outside of the air generator body 2.

[0026] Air enters the first filter chamber 3 through the intake pipe 20 for filtration and adsorption, then enters the second filter chamber 4 through the connecting pipe 21 for further purification, and is then discharged to the outside through the exhaust pipe 22.

[0027] The air generator body 2 has a drive motor 23 fixedly connected to the back side. The other end of the output shaft of the drive motor 23 is fixedly sleeved with a drive shaft 24. The outer surface of the drive shaft 24 is fixedly sleeved with a rotating rod 25. The inner surface of the rotating rod 25 is movably connected with a cylindrical block 26. The bottom of the cylindrical block 26 is fixedly connected with a connecting plate 27. The bottom of the connecting plate 27 is fixedly connected with a sealing plate 28. There are two sealing plates 28. The outer surfaces of the two sealing plates 28 are movably connected to the inner wall of the top of the air generator body 2.

[0028] When the drive motor 23 is running, the drive shaft 24 will drive the rotating rod 25 to rotate. The rotation of the rotating rod 25 will squeeze and push the cylindrical block 26 to move horizontally, which in turn will cause the connecting plate 27 to drive the two sealing plates 28 to move horizontally to release the sealing effect on the top of the first filter chamber 3 and the second filter chamber 4, further improving the convenience of replacing the filter elements inside the first filter chamber 3 and the second filter chamber 4.

[0029] In this process, the top of the first filter chamber 3 and the second filter chamber 4 are fixedly connected with two sealing gaskets 29, and the top of the two sealing gaskets 29 are movably connected to the bottom of the two sealing plates 28 respectively.

[0030] The design of the two sealing gaskets 29 ensures the airtightness of the first filter chamber 3 and the second filter chamber 4.

[0031] Working principle and usage process of this utility model: When purifying the air, the air delivery pipe is first connected to the air inlet pipe 20. Then the air enters the first filter chamber 3 through the air inlet pipe 20. The air is filtered and adsorbed inside the first filter chamber 3 through the air inlet pipe 20. Then it enters the second filter chamber 4 through the connecting pipe 21 for further purification and adsorption. Finally, it is discharged to the outside through the discharge pipe 22.

[0032] After a period of use, the adsorption capacity of the filter elements inside the first filter chamber 3 and the second filter chamber 4 will gradually weaken, requiring replacement. First, start the drive motor 23, which will cause the drive shaft 24 to drive the rotating rod 25 to rotate. The rotation of the rotating rod 25 will squeeze and push the cylindrical block 26 to move horizontally, thereby causing the connecting plate 27 to drive the two sealing plates 28 to move horizontally and release the sealing effect on the top of the first filter chamber 3 and the second filter chamber 4. Then, start the drive motor 6, which will cause the lead screw 7 to rotate and drive the toothed plate 8 to move horizontally. This will cause the toothed plate 8 to mesh with the gear 9, driving the gear 9 and the rotating rod 11 to rotate around the movable shaft 10. This will cause the round shaft 12 to rotate and drive the lifting plate 13 to move upward, further driving the two piston rods 14 and the two piston heads 15 to move upward, respectively pushing the filter elements inside the first filter chamber 3 and the second filter chamber 4 to the outside, thus facilitating filter element replacement.
