There are five types: pre-filters, medium-efficiency filters, high-medium-efficiency filters, sub-high-efficiency filters, and high-efficiency filters. Each type has different standards and performance levels.

[0003] Utility model CN212548759U discloses an air intake volume regulating device for a high-efficiency air filter, including a magnetic ring, a transition sleeve, an air intake cylinder, an air intake plate, and an adjusting plate. A transition sleeve is threaded onto one side of the air intake cylinder, and a magnetic ring is fixedly fitted onto the outer side of the transition sleeve. A first internal thread is formed on one side of the transition sleeve, and a second internal thread is formed on the other side.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An air intake volume regulating device for a high-efficiency air filter includes an air intake duct 1, a rotating ring 2 on the air intake duct 1, a plurality of arc-shaped grooves 3 on the rotating ring 2, a plurality of movable rods 4 slidably connected to the air intake duct 1, a connecting shaft 5 installed on each of the movable rods 4, the plurality of connecting shafts 5 slidably connected in the corresponding arc-shaped grooves 3, and a plurality of grippers 6 are provided at the ends of the plurality of movable rods 4 that are far apart from each other.

[0022] When using this device, it needs to be connected to the air inlet flange on the filter first. During connection, move the device so that the air inlet flange is between several grippers 6. Then, control the rotation of the rotating ring 2, which causes the connecting shaft 5 connected to it via the arc groove 3 to rotate synchronously. The connecting shaft 5 then drives the grippers 6 to move closer together until they contact the air inlet flange, thus achieving the purpose of connecting the device to the filter. The device is simple to use. By controlling the distance between the grippers 6, the device can be connected to filters of different specifications, further improving its practicality and effectively expanding its application range.

[0023] Specifically, in this embodiment, the air inlet duct 1 is provided with a plurality of movable slots 7. The size of the movable slots 7 is adapted to the movable rods 4, so that the plurality of movable rods 4 can be slidably connected to the air inlet duct 1 through the corresponding movable slots 7, thereby restricting the movement direction of the movable rods 4, so that the plurality of movable rods 4 always move around the center of the air inlet duct 1.

[0024] Specifically, in this embodiment, a connecting ring 8 is installed on the side of the air inlet duct 1 near the gripper 6. The outer side of the connecting ring 8 is provided with an internal thread, and the rotating ring 2 is provided with an external thread. This allows the rotating ring 2 to be connected to the connecting ring 8 through the matching of the internal and external threads, thereby facilitating the control of the rotating ring 2 to rotate and drive the moving rod 4 to move. The matching of the internal and external threads provides a locking effect between the rotating ring 2 and the connecting ring 8, preventing the position of the moving rod 4 from shifting.

[0025] Specifically, in this embodiment, a connecting pipe 9 is installed inside the air inlet duct 1. The connecting pipe 9 has a frustum-shaped design and is made of elastic material. When in use, the frustum side of the connecting pipe 9 is inserted into the air inlet flange. The frustum design allows the connecting pipe 9 to be stably connected to air inlet flanges of different specifications, further ensuring the sealing of the connection between the device and the filter.

[0026] Specifically, in this embodiment, each of the several moving rods 4 has an elastic component at one end that is far apart from each other, and several grippers 6 are mounted on the corresponding moving rods 4 through the elastic components. When the length of the connecting pipe 9 in the air inlet flange is different, the elastic connection between the moving rods 4 and the grippers 6 allows the grippers 6 to adapt to the connection requirements of different distances between them and the air inlet flange.

[0027] Specifically, in this embodiment, rubber pads are provided on the side of several grippers 6 that are close to the air inlet flange, so that when the grippers 6 move toward the air inlet flange, the rubber pads first come into contact with the air inlet flange, thereby increasing the friction between the grippers 6 and the air inlet flange and making the connection more stable.

[0028] Specifically, in this embodiment, an air inlet plate 10 is installed inside the air inlet duct 1, and an adjusting plate 11 is rotatably installed. The air inlet plate 10 and the adjusting plate 11 have the same air inlet grooves 13 distributed around their circumference. A lever 12 is installed on the adjusting plate 11. By rotating the lever 12, the adjusting plate 11 is driven to rotate, thereby controlling the coverage area of ​​the air inlet grooves 13 on the air inlet plate 10 and the adjusting plate 11, thereby achieving the purpose of controlling the air intake volume.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
