Description

Technical Field

[0001] The utility model relates to the technical field of cold air pipe cleaning, in particular to a circulating cold air pipe with a self-cleaning function. Background Art

[0002] The circulating air conditioning pipe is a pipeline that transfers the refrigerant from the evaporator to the compressor. It is an important part of the refrigeration cycle. The refrigerant flows in the air pipe to complete the evaporation and condensation process, thereby achieving a cooling effect. When the air conditioning pipe is used for a long time, the internal temperature will be too low, which will cause frost to form on the inner wall of the air conditioning pipe. Therefore, it is necessary to use tools to scrape it off to ensure the normal transmission of the internal cold air.

[0003] Currently, most methods of cleaning the frost inside the air conditioning pipe are to shut down the machine to allow the internal frost to melt, or to use tools to scrape it off. The inner wall of the air conditioning pipe cannot be automatically cleaned and scraped off the frost on the inner wall, which will lead to a decrease in the working efficiency of the machine. Therefore, we propose a circulating air conditioning pipe with a self-cleaning function. Utility Model Content

[0006] By adopting the above technical solution, when the cold air pipe is used, the flowing cold air blows the power fan to rotate, and then the power fan drives the rotating shaft to rotate. When the rotating shaft rotates, it will drive the fixed rod and the connecting rod to rotate. The fixed rod will drive the brush rod to rotate along the inner wall of the first pipe for cleaning. At the same time, the annular tooth groove of the brush rod will push the rotating gear to rotate, and then drive the rotating rod and the brush rod to rotate, so that the brush rod can rotate and clean along the inner wall of the first pipe, thereby achieving the effect of cleaning the inner wall of the first pipe.

[0007] Furthermore, one side of the first pipeline fixedly connected to the limiting pipe is fixedly connected to the limiting block, the other side of the first pipeline is provided with a limiting groove, and one side of the first pipeline provided with the limiting groove is fixedly connected to a rubber ring.

[0008] By adopting the above technical solution, when installing the cold air pipe, the limiting effect can be achieved by inserting the limiting block into the limiting groove, and the sealing effect can be achieved by the rubber ring arranged on one side of the fixing rod. Then, the first pipe and the second pipe are fixed by inserting the bolts into the installation hole, thereby facilitating the installation.

[0009] Furthermore, mounting holes are provided at both ends of the first pipe, and the first pipe and the second pipe have the same internal structure.

[0010] By adopting the above technical solution, the cold air pipe can be installed through the initial installation hole, which can facilitate installation.

[0011] Furthermore, the rotating rod is rotatably connected to the inside of the rotating ring, the connecting rod is fixedly connected to the rotating ring, the rotating shaft is rotatably connected to the inside of the first limit frame and the second limit frame, and the power fan is arranged between the first limit frame and the second limit frame.

[0012] By adopting the above technical solution, the rotation of the connecting rod will drive the rotating ring to rotate, so that the rotating ring can drive the rotating rod and the brush rod to rotate along the inner wall of the first pipe. The first limit frame and the second limit frame can achieve the effect of limiting the rotating shaft and the power fan.

[0013] Furthermore, the rotating gear is meshingly connected with the annular tooth groove, and the annular tooth groove is arranged inside the rotating ring.

[0014] By adopting the above technical solution, the meshing connection between the rotating gear and the annular tooth groove can achieve the effect that when the rotating ring rotates, the annular tooth groove will push the rotating gear to rotate.

[0015] Furthermore, the sizes of the limiting blocks and the limiting grooves are adapted to each other, and there are four of them both. The rubber ring is made of rubber material, and the first pipe and the second pipe are connected by bolts.

[0016] By adopting the above technical solution, the limiting block can be inserted into the limiting groove to achieve the limiting effect, and when the first pipe is connected to the second pipe, the rubber ring can achieve the sealing effect.
