This disclosure provides a water tank assembly, a cleaning device, and a cleaning system. The water tank assembly is installed on the cleaning device and includes a water tank and an overflow structure. The water tank includes a receiving cavity. The overflow structure includes an overflow pipe and a first overflow port and a second overflow port respectively disposed at both ends of the overflow pipe. The first overflow port and at least a portion of the overflow pipe are disposed within the receiving cavity, and the first overflow port is located at a predetermined overflow height within the receiving cavity. The second overflow port is positioned below the first overflow port and connects to the outside of the receiving cavity.

This invention provides a method for preparing porous interconnected hollow carbon nanofiber membranes, belonging to the field of nanomaterial preparation technology. The method first uses a mixture of MOF and a polymer as a shell precursor solution, and SAN resin or PMMA as a core layer precursor solution. A mixed matrix membrane material is prepared through coaxial electrospinning and subsequent carbonization. In the mixed matrix membrane, the SAN resin or PMMA acts as a self-sacrificial template, undergoing carbonization and volatilization to induce the formation of hollow carbon nanofibers. Meanwhile, the MOF induces the formation of porous structures on the hollow carbon nanofibers through interfaces, interconnecting them via hollow channels. This method is simple to operate, streamlined, and can be mass-produced, possessing significant practical application value in the fields of energy catalysis and environmental protection.
