As shown in fig. 2 and 3, specifically, the flushing device 4 is installed at one end of the transparent cylinder 1, and comprises: the washing pipe 41, the nozzle 42 and the water inlet connector 43 are installed on the washing pipe 41, and the nozzle 42 is disposed toward the inside of the transparent cylinder 1.

Wherein, the water inlet joint 43 is used for connecting external pressure water to introduce the external pressure water into the washing pipeline 41, and further spraying the external pressure water onto the wall of the periphery of the transparent cylinder 1 through the nozzle 42 to clean stains. Preferably, the pressure requirement is 3.5-4kg/cm²The flow rate needs 3.0-3.5 m/h. The material of the nozzle 42 is SUS316L, and the height of the spray head and the washing device 4 is controlled to be less than or equal to 0.9mm after installation.

The flushing pipe 41 is composed of a base 411 and a cover plate 412, and the base 411 and the cover plate 412 are fixed by screw connection. In other embodiments, the flushing pipe 41 may be integrally formed. Preferably, the flushing pipe 41 is made of a corrosion/weather resistant material.

In order to facilitate the screw connection between the fixed base 411 and the cover plate 412, the two sides and the end of the flushing pipe 41 are provided with mounting holes 413 suitable for the screw assembly, wherein the mounting holes 413 on the two sides protrude from the sides of the base 411 and the cover plate 412. According to the length requirement of the flushing pipe 41, one or more mounting holes can be arranged on any side, and when the mounting holes 413 are multiple, the mounting holes 413 on two sides are symmetrically arranged.
