DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, an air filter that is easy to replace activated carbon includes a mounting plate 1. The mounting plate 1 is hollow. Through the setting of the hollow type, the connecting mechanism 6 and the activated carbon plate 7 can stably enter the interior of the frame 2, so that the disassembly and assembly of the connecting mechanism 6 and the activated carbon plate 7 can be more stable. The top of the mounting plate 1 is provided with a mounting groove for the connecting plate 601 to be installed. The mounting groove is connected to a slide groove provided on the mounting plate 1. The slide groove is slidably connected to the positioning plate 5. Through the setting of the slide groove, when the spring 4 drives the positioning plate 5 to move, the movement of the positioning plate 5 can be improved. The stability during operation is improved, so that the rebound component can be more stable during operation. A connecting hole is provided on the mounting plate 1, and a threaded strip is fixed inside the connecting hole. Through the setting of the connecting hole, the air filter can be installed on the equipment as a whole to prevent the air filter from being unable to be used normally when the equipment is running. A frame 2 is fixed to the bottom of the mounting plate 1, and two filter screens 3 are movably installed inside the frame 2. Four rebound components are arranged inside the mounting plate 1, and a connecting mechanism 6 is arranged inside the mounting plate 1. A plurality of activated carbon plates 7 are fixed to the bottom of the connecting mechanism 6.

[0022] In this embodiment, the rebound assembly is composed of a spring 4 and a positioning plate 5. The spring 4 is fixed to the inside of the mounting plate 1, the positioning plate 5 is fixed to the top of the spring 4, and the positioning plate 5 is slidably connected to the inside of the mounting plate 1.

[0023] It should be noted that when there is no connection between the connecting mechanism 6 and the mounting plate 1, the pressure on the spring 4 will disappear. At this time, due to the characteristics of the spring 4 itself, the positioning plate 5 will be driven to rebound, so that the positioning plate 5 can drive the connecting mechanism 6 and the activated carbon plate 7 to rise, making it easier to take the connecting mechanism 6 and the activated carbon plate 7.

[0024] See also Figure 4In order to facilitate the replacement of activated carbon, the connecting mechanism 6 in this embodiment includes a connecting plate 601, two supporting plates 602, a rotating rod 603, a rotating disk 604, a first gear 605 and two telescopic components. The left and right sides of the connecting plate 601 are provided with connecting holes, and the connecting holes are adapted to the telescopic cylinder 608. Through the setting of the connecting holes, the operation of the telescopic cylinder 608 can be more stable, thereby improving the stability of the connecting mechanism 6 during operation. The connecting plate 601 is movably connected to the inside of the mounting plate 1, and the two supporting plates 602 are fixed to the inside of the connecting plate 601. The rotating rod 603 is rotatably connected to the top of the connecting plate 601, and the rotating rod 603 passes through the inside of the connecting plate 601. The rotating disk 604 is fixed to the top of the rotating rod 603, and the first gear 605 is fixed to the bottom of the rotating rod 603. The two telescopic components are respectively engaged with the left and right sides of the first gear 605, and the two telescopic components are respectively passed through the left and right sides of the connecting plate 601.

[0025] In this embodiment, the telescopic assembly includes a second gear 606, a threaded rod 607 and a telescopic cylinder 608. The mounting groove is connected to a limiting hole provided on the mounting plate 1, and the limiting hole is adapted to the telescopic cylinder 608. Through the setting of the limiting hole, when the telescopic cylinder 608 is separated from the limiting hole, the connecting mechanism 6 and the mounting plate 1 are in an active state, and then through the action of the rebound assembly, the connecting mechanism 6 can drive the activated carbon plate 7 to rise, thereby making the replacement of the activated carbon plate 7 more convenient. The two second gears 606 are respectively engaged with the left and right sides of the first gear 605, and the two threaded rods 607 are respectively fixed to the opposite side of the two second gears 606, and the two threaded rods 607 respectively penetrate the two support plates 602, and the telescopic cylinder 608 is threadedly connected to the outer surface of the threaded rod 607, and the telescopic cylinder 608 penetrates to the outside of the connecting plate 601.

[0026] It should be noted that, by rotating the turntable 604, the rotating rod 603 can drive the first gear 605 to rotate, and through the engagement of the first gear 605 and the second gear 606, the second gear 606 can drive the threaded rod 607 to rotate, so that the telescopic cylinder 608 threadedly connected to the threaded rod 607 can be extended and retracted, and through the extension and retraction of the telescopic cylinder 608, the connecting mechanism 6 can be fixed and separated from the mounting plate 1, so that the activated carbon plate 7 can be removed from the inside of the air filter more quickly.

[0027] The working principle of the above embodiment is:

[0028] When there is a lot of dust adsorbed on the activated carbon plate 7, the rotating rod 603 can be rotated by rotating the turntable 604, so that the rotating rod 603 can drive the first gear 605 to rotate, and the second gear 606 is meshed with the first gear 605. When the first gear 605 rotates, the second gear 606 will be driven to rotate, so that the second gear 606 can drive the threaded rod 607 to rotate, and the threaded rod 607 is threadedly connected to the telescopic cylinder 608, when the threaded rod 607 rotates, it will drive the telescopic cylinder 608 to be extended and retracted, so that the telescopic cylinder 608 can be separated from the mounting plate 1, and then through the action of the spring 4, the spring 4 can drive the positioning plate 5 to rebound, so that the positioning plate 5 can drive the connecting plate 601 to move upward, so that the connecting mechanism 6 can drive the activated carbon plate 7 to move upward, so that the connecting mechanism 6 and the activated carbon plate 7 can be taken out more quickly, thereby achieving the purpose of facilitating the replacement of the activated carbon plate 7 and improving the efficiency of replacement.
