[0002] Blow-molded hose is a hose product made by blow molding process, and blow-molded hose is commonly used in vacuum cleaners.

[0003] When the blow-molded hose is used on a vacuum cleaner, one end of the blow-molded hose is connected to the vacuum head, and the other end of the blow-molded hose is connected to the dirty bucket. During cleaning, garbage passes through the vacuum head and along the blow-molded hose into the dirty bucket for collection.

[0004] When the blow-molded hose is connected to the vacuum cleaner head, a long elbow is required to be used as an intermediary to avoid the connection between the blow-molded hose and the vacuum cleaner head from breaking due to bending. However, with long-term use, there is a phenomenon of blockage inside the long elbow. However, it is inconvenient to disassemble the long elbow from the vacuum cleaner head, which makes it inconvenient to clean the long elbow. For this reason, we propose a blow-molded hose with a long elbow. Utility Model Content

Only when the extrusion sleeve 301 moves downward, so that the give way groove 401 moves to the position of the positioning ball 202 along with the extrusion sleeve 301, the give way groove 401 will give way to the positioning ball 202, so that the positioning ball 202 cannot be tightly against the inner wall of the slot 201, and the external tube 103 can be pulled out from the long elbow body 102.

[0027] Among them, the connecting mechanism includes a fixing ring 502, which is fixedly sleeved on the outer wall of the long elbow body 102, and an annular groove 501 is provided on the inner wall of the extrusion sleeve 301.
