Detailed Implementation

[0026] 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.

[0027] Example

[0028] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0029] An opening and closing mechanism for a weather conversion device for a shielded door includes: a mounting frame 1, with multiple rotating shafts 2 rotatably connected to both sides of the mounting frame 1; two adjusting fan blades 3 fixedly connected to the inner side of the rotating shafts 2; connecting arms 4 fixedly attached to the surface of the adjusting fan blades 3; connecting plates 5 provided on the surface of the multiple connecting arms 4; an adjusting component 6 for moving the connecting plates 5 on one side of the mounting frame 1; and a dust removal component 7 installed at the bottom of the mounting frame 1. The adjusting component 6 activates the connecting plates 5, which, under the action of the connecting arms 4, causes the rotating shafts 2 and adjusting fan blades 3 to adjust their angles, thereby opening and closing the door. Subsequently, negative ions are blown out by the dust removal component 7, which can bind with air pollutants, making them heavier and causing them to settle to the ground, thus reducing the harm of pollutants to the human body and increasing the practicality of the mechanism.

[0030] Specifically, two adjustable fan blades 3 are installed in a rhomboid shape on the surface of the rotating shaft 2. The adjustable fan blades 3 include a base material layer, a heat insulation layer, a surface treatment layer, and a conductive coating from the inside out. The base material layer is made of aluminum alloy, which makes the adjustable fan blades 3 lightweight, high-strength, and corrosion-resistant. The heat insulation layer is made of aerogel, which increases the heat insulation effect of the adjustable fan blades 3. The surface treatment layer is an anodized electroplated chromium layer, which can improve wear resistance and corrosion resistance, while enhancing the surface gloss and rust prevention. The conductive coating is a carbon fiber coating, which provides an electrostatic discharge function to prevent safety problems caused by static electricity accumulation.

[0031] In a specific embodiment of this utility model, by adjusting the shape of the fan blade 3, it is convenient to seal the inner side of the mounting frame 1, and at the same time, it is convenient to guide the airflow.

[0032] Specifically, the adjustment component 6 includes a mounting base 601 and a mounting plate 606 mounted on the surface of the mounting frame 1. A first threaded rod 602 is rotatably connected to the surface of the mounting base 601. A first internal threaded block 603 is threadedly connected to the surface of the first threaded rod 602. A movable plate 604 is fixed to the surface of the first internal threaded block 603. A movable column 605 is provided on the surface of the movable plate 604, and the movable column 605 is rotatably connected to the connecting plate 5. A first servo motor 608 is mounted on the surface of the mounting frame 1 on one side of the first threaded rod 602, and the output shaft of the first servo motor 608 is fixedly connected to the first threaded rod 602. A second sliding groove 609 is opened on the surface of the movable plate 604, and the movable column 605 is slidably connected to the surface of the second sliding groove 609. A first sliding groove 607 is opened on the surface of the mounting plate 606, and the movable column 605 is slidably connected to the surface of the first sliding groove 607.

[0033] In a specific embodiment of this utility model, when it is necessary to open the adjusting fan blade 3, the first servo motor 608 is activated. The output shaft of the first servo motor 608 drives the first threaded rod 602 to rotate. The rotation of the first threaded rod 602 drives the first internal threaded block 603 and the moving plate 604 to move. The movement of the moving plate 604 drives the moving column 605 to move on the surface of the moving plate 604 under the action of the second slide groove 609. At the same time, the moving column 605 moves on the surface of the mounting plate 606 under the action of the first slide groove 607, thereby driving the connecting plate 5 to move.

[0034] Specifically, the dust removal component 7 includes a support frame 701 installed on one side of the bottom of the mounting frame 1. A second threaded rod 702 is rotatably connected to the surface of the support frame 701. A second internal threaded block 703 is threadedly connected to the surface of the second threaded rod 702. A negative ion generator 704 is installed on the surface of the second internal threaded block 703. A second servo motor 706 is installed on one side of the support frame 701. A pulley 707 is fixedly connected to one end of the output shaft of the second servo motor 706 and the outer side of the second threaded rod 702. The two pulleys 707 are rotatably connected through a transmission belt 708.

[0035] In a specific embodiment of this utility model, the second servo motor 706 starts its output shaft, which drives the second threaded rod 702 to rotate under the action of the pulley 707 and the transmission belt 708. The rotation of the second threaded rod 702 drives the second internal threaded block 703 and the negative ion generator 704 to move, and negative ions can be generated by the negative ion generator 704.

[0036] Specifically, the dust removal component 7 also includes a guide rail 705 installed on the other side of the bottom of the mounting frame 1, and the negative ion generator 704 is slidably connected to the surface of the guide rail 705.

[0037] In a specific embodiment of this utility model, the negative ion generator 704 moves on the surface of the guide rail 705 when it moves, thereby increasing the stability of the negative ion generator 704 when it moves.

[0038] Working principle: By starting the first servo motor 608, the output shaft of the first servo motor 608 drives the first threaded rod 602 to rotate. The rotation of the first threaded rod 602 drives the first internal threaded block 603 and the moving plate 604 to move. The movement of the moving plate 604 drives the moving column 605 to move on the surface of the moving plate 604 under the action of the second slide groove 609. At the same time, the moving column 605 moves on the surface of the mounting plate 606 under the action of the first slide groove 607, thereby driving the connecting plate 5 to move. Under the action of the rotating shaft 2 and the adjusting fan blade 3, the angle is adjusted to achieve opening and closing. Then, the second servo motor 706 starts and its output shaft drives the second threaded rod 702 to rotate under the action of the pulley 707 and the transmission belt 708. The rotation of the second threaded rod 702 drives the second internal thread block 703 and the negative ion generator 704 to move. At this time, negative ions can be generated by the negative ion generator 704, which can combine with pollutants in the air, make them heavier and settle to the ground, thereby reducing the harm of pollutants to the human body and increasing the practicality of the mechanism.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
