Description

Technical Field

[0001] This utility model relates to the field of air supply device technology, and in particular to a refrigeration air supply mechanism based on central air conditioning. Background Technology

[0002] Central air conditioning is a system that centrally handles indoor air conditioning loads, achieving indoor air conditioning through the transfer of cooling (heating) media. It is suitable for large spaces such as homes and office buildings, offering convenience and comfort. Residential central air conditioning systems can be divided into three types: duct systems, chilled (heated) water systems, and refrigerant systems.

[0003] The outdoor unit of an air conditioner generates airflow, which is then delivered to various rooms through ducts. However, this has certain limitations. On the one hand, when there are many rooms and a large area, the airflow power of the outdoor unit is limited, and rooms located further away receive less airflow, affecting the air supply effect. On the other hand, the ducts are equipped with filters to ensure the air quality delivered to the rooms, but over time, the filters will become clogged, reducing the airflow. To solve these problems, a refrigeration and air delivery mechanism based on central air conditioning is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a refrigeration and air supply mechanism based on central air conditioning.

The spur gear 13 meshes with the toothed arc plate 21. A brush plate 18 is fixedly connected to the surface of the linkage shaft 10. The lower surface of the brush plate 18 is in contact with the upper surface of the first filter screen 8.

[0027] In this invention, air is filtered by setting a first filter screen 8 and a second filter screen 7. A motor 9 drives the fan blades 19 to rotate, which in turn transports air and enhances the air transport effect. A support column 20 provides rotational support for the toothed arc plate 21. A U-shaped plate 22 drives the swing plate 24 to swing. A linkage shaft 10 keeps the spur gear 13 stable, allowing the spur gear 13 to drive the linkage shaft 10 to swing back and forth. A brush plate 18 removes dust and impurities from the first filter screen 8 to prevent clogging and ensure the air transport of the air conditioner.

[0028] The top end of the linkage shaft 10 is fixedly connected to the first bevel gear 14, the inner wall of the housing 1 is rotatably connected to the rotating shaft 17, and one end of the rotating shaft 17 is fixedly connected to the second bevel gear 15.

[0029] In this invention, a second bevel gear 15 is provided to drive the rotating shaft 17 to rotate.

[0030] A sweeping plate 16 is fixedly connected to the surface of the rotating shaft 17, and the first bevel gear 14 meshes with the second bevel gear 15.

[0031] In this invention, a sweeping plate 16 is provided to sweep the dust and debris attached to the brush plate 18 into the collection bucket 6 for collection.

[0032] A fixing plate 11 is fixedly connected to the surface of the box 1, a positioning pin 12 is slidably connected to the inner wall of the fixing plate 11, and a collection bucket 6 is inserted into the inner wall of the box 1.

[0033] In this utility model, by setting a fixing plate 11, the sliding stability of the positioning pin 12 is maintained, and by setting the positioning pin 12, the collection bucket 6 is positioned and fixed.

[0034] The surface of the collection bucket 6 is provided with a positioning groove 26, and the inner wall of the positioning groove 26 is adapted to the positioning pin 12.

[0038] Working principle: In use, after the housing 1 is installed and fixed, air generated by the air conditioner is introduced into the housing 1. At the same time, the motor 9 is started. The motor 9 drives the U-shaped plate 22 to rotate. The rotation of the U-shaped plate 22 drives the fan blade 19 to rotate through the drive shaft 23. The rotation of the fan blade 19 enhances the delivery of air in the housing 1, ensuring that the air can be delivered to a greater distance through the housing 1. The movement of the U-shaped plate 22 causes the mounting hole 25 to be stressed, causing the toothed arc plate 21 to swing around the support column 20. When the toothed arc plate 21 moves, it drives the spur gear 13 to rotate reciprocally. The reciprocating rotation of the spur gear 13 drives the linkage shaft 10 and the first bevel gear 1 4. Reciprocating motion: The linkage shaft 10 rotates through the brush plate 18 to remove the sticky objects adhering to the surface of the first filter screen 8. The first bevel gear 14 drives the rotating shaft 17 to rotate through the second bevel gear 15. The rotation of the rotating shaft 17 drives the sweeping plate 16 to rotate. The sweeping plate 16 sweeps the dust adhering to the surface of the first filter screen 8 into the collection bucket 6 for collection. When processing the dust, the positioning pin 12 is pulled out to release the limit on the collection bucket 6, and the collection bucket 6 is pulled out to process the dust. With the above structure, it is ensured that air can be delivered to a longer distance in the pipeline, while preventing the filter screen from becoming clogged and affecting the air flow due to long-term use.
