Cleaning apparatus

A cleaning device, comprising:

• a main body, a cleaning assembly, and a connection mechanism;
• a cleaning liquid supply system comprising a cleaning liquid reservoir and a cleaning liquid output pipeline, wherein the cleaning liquid reservoir is connected to the cleaning liquid output pipeline;
• and
• a dirt recovery system comprising a dirt reservoir, a dirt suction pipeline, and a fan assembly, wherein the dirt reservoir is communicated with the dirt suction pipeline and further in fluid communication with the fan assembly, wherein;
• the connection mechanism is configured to connect the main body and the cleaning assembly, and comprises at least two rotational connection portions, rotation axes of which not being parallel to each other;
• the at least two rotational connection portions are configured to enable the main body to rotate relative to the cleaning assembly about the rotation axis of each of the at least two rotational connection portions;
• the at least two rotational connection portions comprise a first rotational connection portion and a second rotational connection portion, and the first rotational connection portion is configured to enable the main body to rotate relative to the cleaning assembly about a first rotation axis of the first rotational connection portion;
• the first rotational connection portion comprises a first connection member, a second connection member and at least one first pivoting member;
• the first connection member and the second connection member in the first rotational connection portion are further provided with a first passage for arrangement of a circuit and the cleaning liquid output pipeline, and a second passage for arrangement of the dirt suction pipeline;
• and
• the second connection member is rotatably connected to the first connection member via the at least one first pivoting member, the first passage is on the outside of the first pivoting member, and the second passage is between two first pivoting members.
