DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The moving part 4 can make the upper end bracket 3 move upward along the slide rail 101 to straighten the filling hose 01; the knocking bracket 5 is slidably connected to the slide rail 101 and is located between the lower end bracket 2 and the upper end bracket 3. The knocking part 6 is arranged on the knocking bracket 5, and the knocking part 6 can knock the filling hose 01. The knocking bracket moving part 7 is arranged on the main bracket 1, and the knocking bracket moving part 7 can make the knocking bracket 5 move up and down along the slide rail 101 to drive the knocking part 6 to knock the filling hose 01 along its extension direction, so as to make the impurities in the filling hose 01 fall off.

[0029] It should be noted that since the filling hose 01 is usually a corrugated hose, the corrugated structure inside the filling hose 01 is prone to retain some impurities, which is the main factor affecting the cleanliness of the filling hose. Therefore, the present device is used to straighten the filling hose 01 and perform full coverage and no-dead-angle knocking. By observing the impurities that fall from the bottom of the filling hose 01 when knocking (a pull-out plate can be set under the lower end bracket 2, and a clean white cloth strip can be placed on the pull-out plate to catch the impurities that fall from the filling hose 01 when knocking, which is convenient for observation), the cleanliness of the filling hose can be judged, thereby realizing automatic detection of the cleanliness of the filling hose, improving detection efficiency, and saving manpower labor.

[0030] In this embodiment, the main bracket 1 is preferably a rectangular structure with a length of 800 mm, a width of 500 mm, and a height of 3500 mm.
