Detailed Implementation

[0017] 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. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-5 An adjustable PVC louvered air vent for central air conditioning includes a housing 2, which is the outer shell of the air outlet blades of the central air conditioning unit. The housing 2 is installed at the bottom of the air conditioning unit housing 1. A through groove 8 is provided inside the air conditioning unit housing 1, and the housing 2 is located inside the through groove 8. In particular, the top outer wall of the housing 2 is integrally formed with two sliders 4, and the top inner wall of the air conditioner housing 1 is provided with two first sliding grooves 3, and the sliders 4 are slidably connected to the first sliding grooves 3. Through the cooperation of the sliders 4 and the first sliding grooves 3, the housing 2 is guided, which facilitates its positioning and installation. Multiple air outlets 9 are provided on one side of the housing 2. Each air outlet 9 is rotatably connected to a rotating shaft 16. A blade 7 is fixed on the outside of the rotating shaft 16. The blade 7 is a curved blade type with an arc groove at its bottom. The blade 7 is made of PVC, which makes the blade 7 durable, not easy to fade or change color, and its surface is smooth, making it difficult for dust to adhere and easy to clean and maintain. The blade 7 can cover the air outlets 9. One end of each of the multiple rotating shafts 16 passes through the housing 2 and is keyed to a synchronous pulley 15. The multiple synchronous pulleys 15 are connected to each other by a synchronous belt 18. A power assembly for driving the rotating shafts 16 to rotate is provided on one side of the outer wall of the housing 2. The power assembly includes a motor 14. The motor 14 and one end of one of the rotating shafts 16 are fixedly connected by a coupling. The rotation of the motor 14 causes the rotating shaft 16 to drive the blades 7 to rotate, thereby adjusting the size of the blades 7 blocking the air outlet 9.

[0019] A dust cover 6 is fixed to one side of the outer wall of the housing 2 by bolts. The dust cover 6 has threaded holes, and the motor 14 is fixed inside the dust cover 6 by installing bolts from the outside. The dust cover 6 is located inside the through groove 8, and the motor 14 and the synchronous pulley 15 are also located inside the dust cover 6. A filter hole is provided on one side of the dust cover 6, which not only protects the inside of the dust cover 6, but also provides heat dissipation and auxiliary dust prevention. The motor 14 is a stepper motor, model MP24GA 24BYJ48-C01. The motor 14 can be electrically connected to the control panel on the central air conditioner through an external encoder and control module. The opening and rotation angle of the motor 14 can be controlled by operating the control panel.

[0020] Place housing 2 into air conditioner housing 1, and move slider 4 along the first slide groove 3 until it is completely inside air conditioner housing 1. At this time, the exposed outer side of housing 2 is on the same horizontal plane as air conditioner housing 1. like Figure 4 As shown, the top of the housing 2 has two mounting slots 19, and a spring telescopic rod 17 is fixed in each of the two mounting slots 19 by bolts. The extended end of the spring telescopic rod 17 is fixed with a bevel block 11 by bolts. like Figure 5 As shown, two inclined slots 13 are formed on the top inner wall of the air conditioner housing 1, and the inclined block 11 is inserted into the inclined slot 13 at the corresponding position. As the housing 2 enters the air conditioner housing 1, the inclined surface at the top of the inclined block 11 contacts the inner top wall of the air conditioner housing 1 and is compressed, causing the spring telescopic rod 17 to retract. At this time, the spring in the spring telescopic rod 17 retracts, and the housing 2 moves toward the interior of the air conditioner housing 1 until the inclined block 11 and the inclined groove 13 are vertically aligned. At this time, the spring in the spring telescopic rod 17 rebounds, causing the spring telescopic rod 17 to extend, thereby allowing the inclined block 11 to be inserted into the inclined groove 13, thus achieving the positioning and installation of the housing 2.

[0021] It should be noted that two second sliding grooves 12 are provided on the top of the side of the housing 2, and the second sliding grooves 12 are connected to the adjacent mounting grooves 19. An L-shaped plate 5 is welded to one side of the inclined block 11, and the L-shaped plate 5 is slidably connected to the second sliding grooves 12. When it is necessary to remove the housing 2 from the air conditioner housing 1, press down on the L-shaped plate 5 to make it move down along the second slide groove 12, so that the inclined block 11 moves down and separates from the inclined groove 13, and the housing 2 can be pulled out from the air conditioner housing 1 to achieve separation. Working principle: During installation, the housing 2 is placed into the air conditioner housing 1, and the slider 4 moves along the first slide groove 3 until it is completely inside the air conditioner housing 1. At this time, the unobstructed outer side of the housing 2 is at the same level as the end of the air conditioner housing 1. Simultaneously, as the housing 2 enters the air conditioner housing 1, the inclined surface at the top of the inclined block 11 contacts the inner top wall of the air conditioner housing 1 and is compressed, causing the spring telescopic rod 17 to retract. At this time, the spring in the spring telescopic rod 17 retracts, and the housing 2 moves towards the interior of the air conditioner housing 1 until the inclined block 11 and the inclined groove 13 are vertically aligned. At this time, the spring in the spring telescopic rod 17 rebounds, causing the spring telescopic rod 17 to extend, thereby allowing the inclined block 11 to be inserted into the inclined groove 13, realizing the positioning and installation of the housing 2, and then installing the air conditioner housing 1 in the predetermined position.

[0022] When the angle of the blade 7 needs to be adjusted, the motor 14 is started. The rotation of the motor 14 causes the shaft 16 to rotate the blade 7, thereby adjusting the size of the blade 7 blocking the air outlet 9.

[0023] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
