For example, the Chinese utility model patent with application number CN202121403718.7 discloses "A fiberglass storage tank with multi-layer insulation". In this device, the second connecting pipe allows the user to connect the number of second tank bodies required by the user end to end, and the first connecting pipe and the second connecting pipe allow the first tank body and the second tank body to be connected end to end with the second tank body after length adjustment, so that the device can adjust the length of the device according to user needs, thereby achieving the effect of increasing the use range of the device.

[0004] Although the above-mentioned multi-layer insulated storage tank has certain advantages in making the insulated storage tank more flexible and enabling it to adjust its footprint, it still has certain disadvantages: each layer of the multi-layer insulated storage tank is made of a material with good thermal insulation effect and has thermal insulation capacity, and the multi-layer insulated storage tank is prone to dirt on the inner wall surface after use. If the inner wall of the storage tank is not cleaned in time, the dirt will accumulate, resulting in the insulation effect being hindered. Utility Model Content
