Description

Technical Field

[0001] The utility model relates to the technical field of hoses, in particular to a replaceable split hose. Background Art

[0002] A hose is a flexible tubular object usually made of plastic, rubber or other flexible materials, used to transport fluids such as gas, liquid, etc.

[0003] A Chinese patent application with the publication number CN208169736U discloses a hose made of food-grade PVC material. The hose is odorless, hygienic, and environmentally friendly. It can be used normally in a low-temperature environment of -40°C without cracking and has excellent low-temperature resistance. Both the inner and outer tubes are made of PVC material, which is soft, elastic, and corrosion-resistant. The braided cloth tube has a protective effect and can effectively improve wear resistance. The joint and the hose body are firmly connected and can withstand high-strength tensile forces.

[0004] When using the above patent, we found that the device is not convenient for filtering the liquid flowing inside the hose, which causes impurities and particles to easily flow through the hose, thereby easily causing damage to downstream equipment and systems. Therefore, we proposed a replaceable split hose. Utility Model Content
