Description

Technical Field

[0001] This application relates to the technical field of air-conditioning components, and particularly to an air-conditioning duct structure with multiple protections. Background Art

[0002] An air-conditioning duct is a pipe used to convey air in an air-conditioning system, usually made of metal (such as galvanized steel sheet, stainless steel, etc.), plastic (such as PVC, PE, etc.) or composite materials. These materials have certain strength and durability and can withstand the pressure and vibration generated by air flow. The shape of the pipe is generally circular or rectangular and is selected according to different installation spaces and air flow requirements.

[0003] In a ground central air-conditioning system, the air-conditioning air outlet set on the ground is more likely to let in external dust and sundries, which will affect the air circulation. In addition, moisture or mosquitoes may also enter the air-conditioning system through the duct, damaging the internal components of the air-conditioning system and bringing troubles to people.

[0004] Therefore, it is necessary to provide an air-conditioning duct structure with multiple protections, which adopts a combination of a grille, a mosquito net and a water-avoiding elbow to effectively avoid the above problems, ensure the stability of the internal components of the air-conditioning, and make the air-conditioning system operate stably.

[0031] Embodiment 1:

[0032] Combined with Figures 1-4 , the embodiment of this application discloses an air-conditioning duct structure with multiple protections, including an air outlet plate 1. A water-avoiding elbow 2 is connected to the bottom of the air outlet plate 1. A air supply duct 3 is connected to the right side of the water-avoiding elbow 2. A grille plate 6 is clamped in the inner cavity of the air outlet plate 1. An inner support column 7 is fixedly connected to the inner cavity of the grille plate 6. A support column 8 is fixedly connected to the inner cavity of the air outlet plate 1. The bottom of the inner support column 7 is in contact with the top of the support column 8. A locking structure 9 is arranged between the inner support column 7 and the support column 8. Rectangular slots 10 are opened at both ends on the front side of the inner support column 7. A dense mesh 11 is inserted into the inner cavity of the rectangular slot 10. A drain pipe 4 connected to it is fixedly connected to the left side of the bottom of the inner cavity of the water-avoiding elbow 2. A sealing cover 5 is threadedly connected to the left end of the drain pipe 4. Through the cooperation of the drain pipe 4 and the sealing cover 5, it is convenient for the user to clean the water or dust that may enter the inner cavity of the water-avoiding elbow 2, thereby preventing long-term accumulation and affecting the air output volume of the water-avoiding elbow 2 and the air supply duct 3. A balance bracket 12 is welded to the bottom of the water-avoiding elbow 2.

[0033] Embodiment 2:

[0034] Combined with Figure 3 and Figure 4, the locking structure 9 includes circular grooves 91 formed on the front and rear sides of the top of the inner support column 7. The inner cavity of the circular groove 91 is rotatably connected with a limit pin 92. The front and rear sides of the top of the support column 8 are fixedly connected with fixed tubes 93 respectively. The bottom end of the limit pin 92 is inserted into the inner cavity of the fixed tube 93. Limit convex buttons 94 are fixedly connected to the bottom of the front and rear sides of the limit pin 92. Limit card slots 95 adapted to the limit convex buttons 94 are provided on both sides of the top of the fixed tube 93. A spring 96 is sleeved on the surface of the limit pin 92. The top and bottom ends of the spring 96 are welded to the limit pin 92 and the circular groove 91 respectively. Through the setting of the locking structure 9, the cooperation of the limit pin 92, the fixed tube 93, the limit convex button 94 and the limit card slot 95 plays a role in connecting and fixing the inner support column 7 and the support column 8, enabling the grille plate 6 to stably cover the inner cavity of the air outlet plate 1. At the same time, it is convenient for the user to disassemble the inner support column 7 and the grille plate 6, facilitating the user to repair and maintain the inside of the air outlet plate 1.

[0035] Working principle: When the utility model is in use, the user first inserts the dense mesh 11 into the inner cavity of the rectangular slot 10 and covers the grille plate 6 on the inner cavity of the air outlet plate 1, so that the limit pin 92 is inserted into the inner cavity of the fixed tube 93, and at the same time the limit convex button 94 enters the inner cavity of the limit card slot 95. Subsequently, the user presses down the limit pin 92 to compress the spring 96, and rotates the limit pin 92 to drive the limit convex button 94 to rotate in the inner cavity of the limit card slot 95. Then the limit pin 92 is released, and the spring 96 rebounds and drives the limit pin 92 to reset upward, so that the limit convex button 94 moves upward and stably engages with the top of the inner cavity of the limit card slot 95. During the use process, air is supplied through the air supply pipe 3 and passes through the inner cavity of the water avoidance elbow 2, and is discharged from the top of the air outlet plate 1. The inner support column 7 isolates foreign objects from the outside to prevent foreign objects from entering the inner cavities of the water avoidance elbow 2 and the air supply pipe 3. At the same time, the dense mesh 11 isolates mosquitoes to avoid mosquitoes from entering. Through the shape design of the inner cavity of the water avoidance elbow 2, the entering moisture is isolated to prevent moisture from entering the inner cavity of the air supply pipe 3. During regular maintenance and inspection, the user can rotate the sealing cover 5 to make the sealing cover 5 separate from the surface of the drain pipe 4, and drain the possible accumulated water in the inner cavity of the water avoidance elbow 2 through the drain pipe 4.

[0036] In summary: For this air duct structure with multiple protections, through the setting of the locking structure 9, the grille plate 6 can be quickly installed in the inner cavity of the air outlet plate 1. Through the cooperation of the grille plate 6, the water avoidance elbow 2 and the dense mesh 11, foreign objects, moisture and mosquitoes from the outside are isolated respectively, enabling the air outlet plate 1 and the air supply pipe 3 to maintain stable air volume operation, and thus achieving the purpose of effectively protecting against the influence of multiple external factors on stable operation.

[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
