[0005] However, the above patent still has some problems in actual use. The most obvious one is that it is not convenient to filter impurities in the water during the process of filling water into the water tank, resulting in impurities being injected into the water tank along with the water. In the subsequent use process, impurities enter the water pump and cause damage to the water pump.

[0006] For this reason, we propose a water tank for fire trucks to solve the above-mentioned drawbacks. Utility Model Content
