Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning pipe technology, and in particular to an anti-clogging mechanism for automotive air conditioning pipes. Background Technology

[0002] After prolonged use, automotive air conditioning piping systems are prone to blockages due to the accumulation of impurities and aging of the refrigerant. For example, long-term use can lead to clogged filters and desiccant failure, preventing the interception of moisture and impurities in the refrigerant. This results in sludge-like deposits forming in subsequent pipes. Using inferior refrigerants or mixing different types of refrigerants can trigger chemical reactions that produce corrosive substances that adhere to the inner walls of the pipes and gradually obstruct refrigerant flow. Therefore, when pipes become blocked, the air conditioning system needs to be disassembled, including removing the pipes, replacing the dryer filter, and cleaning the evaporator and condenser. This process is not only cumbersome and time-consuming, resulting in high repair costs, but also fails to provide preventative cleaning. It only addresses the problem passively after symptoms appear, which can easily lead to compressor overload and damage, further increasing repair costs. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an anti-clogging mechanism for automotive air conditioning pipes, which facilitates quick and easy unclogging of the pipe interior, reduces the risk of blockage, and has a simple and convenient structure.

[0004] This utility model also provides an anti-clogging mechanism for an automotive air conditioning pipe as described above, comprising: a conduit, which is the main flow channel of the automotive air conditioning pipe; two side pipes, which are respectively fixed at both ends of the conduit; two electric winding boxes, which are respectively disposed on the side of the two side pipes away from the conduit; a thin rope, the two ends of which pass through the conduit and are fixed inside the electric winding box with the side pipes; and a silicone block, which is fixed to the thin rope and has multiple through holes on its surface.

[0005] According to the present invention, an anti-clogging mechanism for automotive air conditioning pipes includes a sealing cap on the surface of the side pipe, through which a thin rope is threaded. This improves the sealing performance of the side pipe.

[0006] According to the present invention, an anti-clogging mechanism for automotive air conditioning pipes includes two dirt collection grooves on the surface of the silicone block, and the edge of the silicone block has an arc-shaped cut surface. This facilitates the collection of impurities scraped off the silicone block.

[0007] According to the present invention, an anti-clogging mechanism for automotive air conditioning pipes is provided, wherein the inner diameter of the side pipe and the conduit are the same, and the silicone block is in contact with the inner wall of the side pipe and the conduit. This improves the effectiveness of the silicone block.

[0008] According to the present invention, an anti-clogging mechanism for automotive air conditioning pipes includes a polyurethane foam pad fixedly connected inside the sealing cover, which contacts a silicone block. This seals and separates impurities pushed by the silicone block.

[0009] According to the present invention, an anti-clogging mechanism for an automotive air conditioning pipe includes a PTFE coating on the surface of the thin rope, and the length of the thin rope is greater than the length of the conduit. This reduces the friction experienced by the rope.

[0010] According to the present invention, an anti-clogging mechanism for automotive air conditioning pipes includes an electrically operated winding box located at the side pipe contact point, and the electrically operated winding box is equipped with a control module connected to the automotive in-vehicle central control system. This improves the convenience of using the electrically operated winding box. Beneficial effects

[0011] This technical solution provides an anti-clogging mechanism for automotive air conditioning pipes. It involves adding a side plate to the side of the pipe and using an electric winding box to wind up a thin rope arranged inside the pipe. During winding, the rope pulls on a silicone block that is tightly attached to the inner wall of the pipe, scraping away impurities. The through-holes on the surface of the silicone block allow it to move freely within the pipe during air conditioning use. Combined with the freely openable electric winding box, this achieves real-time pipe clearing, improving the anti-clogging performance of the curved sections of the air conditioning pipe.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-4 This utility model provides an anti-clogging mechanism for an automotive air conditioning pipe, comprising: a conduit 1, which is the main flow channel of the automotive air conditioning pipe; two side pipes 2, which are fixed at both ends of the conduit 1; two electric winding boxes 3, which are respectively located on the side of the two side pipes away from the conduit 1; a thin rope 4, whose two ends pass through the conduit 1 and are fixed inside the electric winding boxes 3 with the side pipes 2; and a silicone block 5, which is fixed to the thin rope 4 and has multiple through holes 8 on its surface.

[0016] A sealing cap 6 is provided on the surface of the side tube 2. The sealing cap 6 is pierced by a thin rope 4. The side tube 2 is used to close the side tube 2 under normal conditions to improve the overall sealing of the catheter 1.

[0017] The surface of the silicone block 5 is provided with two dirt collection grooves 7, and the edge of the silicone block 5 is provided with an arc-shaped cut surface. The dirt collection grooves 7 are used to collect the impurities scraped off by the silicone block 5.

[0018] The inner diameter of the side tube 2 is the same as that of the conduit 1. The silicone block 5 is in contact with the inner wall of the side tube 2 and the conduit 1. The relationship between the silicone block 5 and the inner wall of the side tube 2 and the conduit 1 improves the smoothness of the silicone block 5 entering the conduit 1 and moving inside the conduit 1.

[0019] A polyurethane foam pad 9 is fixedly connected inside the sealing cover 6. The polyurethane foam pad 9 is in contact with the silicone block 5. The polyurethane foam pad 9 uses its own pores and adsorption properties to separate the sludge scraped off by the silicone block 5 from the silicone block 5.

[0020] The surface of the string 4 is coated with PTFE, and the length of the string 4 is greater than the length of the conduit 1. The length of the string 4 and the coating treatment extend the service life of the string 4, while ensuring that the silicone block 5 can stably pass through the two side tubes 2.

[0021] The electrically operated winding box 3 is located at the contact point of the side pipe 2, and is equipped with a control module connected to the vehicle's central control system. The electrically operated winding box 3 is controlled to start and stop via wireless commands sent from the vehicle's central control system, ensuring that users can freely use the silicone block 5 to manage the air conditioning pipes.

[0022] Working principle: Under normal conditions, the silicone block 5 is located inside one of the side tubes 2 (the following description assumes that the silicone block 5 is located in the upper side tube 2 of the conduit 1 under normal conditions). Both side tubes 2 are closed by the sealing cover 6. When the air conditioner is in use, the electric winding box 3 corresponding to the lower side tube 2 is opened to wind up the thin rope 4. Since the silicone block 5 is directly fixed to the thin rope 4, the thin rope 4 is directly pulled to move the silicone block 5 to the position of the lower side tube 2 after being wound up. During the movement of the silicone block 5, the impurities on the inner wall of the conduit 1 are pushed closer to the lower side tube 2. During this process, the airflow in the air conditioning pipe passes through the through hole 8, and the impurities attached to the inner wall of the pipe are directly scraped off by the silicone block 5. Since the edge of the silicone block 5 is a rounded tang, it achieves the effect of shoveling the impurities into the collection tank 7. Therefore, the silicone block 5 carries the impurities into the other side tube 2 and comes into contact with the polyurethane foam pad 9. Since the core blockage of the air conditioning pipe is sludge and gel deposits, which are highly adhesive, and the surface of the silicone block 5 is smoother than the surface of the polyurethane foam pad 9, the impurities are transferred to the polyurethane foam pad 9.

[0023] The electric winding box 3 can be directly controlled by the vehicle's hollow system. Therefore, the electric winding box 3 can be opened at will to drive the silicone block 5 to slide and comb the pipe inside the pipe, thereby avoiding the accumulation of large areas of impurities in the pipe. When performing car maintenance or when regularly cleaning the polyurethane foam pad 9, the sealing cover 6 can be removed from the side pipe 2 to completely remove the silicone block 5 and clean the impurities concentrated in the silicone block 5.

[0024] In the automotive air conditioning system, different types of ducts 1 are adapted to different materials of thin ropes 4. For example, for high-temperature ducts near the compressor (such as exhaust pipes), aramid fibers or PTFE fibers are preferred to ensure high-temperature resistance; for low-temperature ducts from the evaporator to the compressor (such as intake pipes), ultra-high molecular weight polyethylene fibers can be selected; for duct areas with more bends, ultra-high molecular weight polyethylene fibers or PTFE fiber braided ropes with better flexibility are preferred.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
