Therefore, the inlet blocker 1130 in the wastewater tank 1100 is used to stop the incoming airflow at first and then make the airflow enter the bottom of the wastewater tank 1100.
  • the inlet blocker 1130 can adopt to any structural form to cooperate with the inner wall of the wastewater tank 1100, thereby forming an inlet drainage channel 1131 for airflow.
  • the inlet blocker 1130 can also be formed to cooperate with the location (for example, top or side) of the fluid inlet 1110 on the wastewater tank 1100 in order to make the inlet blocker 1130 play a role in blocking the airflow when the airflow enters the wastewater tank 1100 through the fluid inlet 1110.
  • the inlet blocker 1130 blocks the airflow.
  • the inlet blocker 1130 can be laterally configured in the inner cavity of the wastewater tank 1100.

  • the inlet blocker 1130 may be longitudinally configured in the inner cavity of the wastewatertank 1100.
  • two inlet drainage channels 1131 in opposite directions are formed between the inlet blocker 1130 and the inner walls on opposite sides of the wastewater tank 1100.
  • the airflow can pass through the inlet blocker 1130 into two symmetrical bundles and enter the interior of the wastewater tank 1100.
  • those skilled in the art can also set the position of the inlet blocker 1130 according to actual requirements, which is not limited here.
  • the inner wall of the wastewater tank 1100 is an arc-shaped inner wall surface, such as a circular inner wall surface, or the cross-section of the inner wall of the wastewater tank 1100 is annular.
  • the air stream of the accommodation cavity flows to the wastewater tank 1100 and, after entering through the fluid inlet 1110 of the wastewater tank 1100, when the inner wall of the wastewater tank 1100 is an arc-shaped inner wall or the cross-section of the inner wall is annular, the two or more streams divided by the inlet blocker 1130 can move along the circular or annular inner wall of the wastewater tank 1100, then the inlet blocker 1130 makes the multiple air streams collide in the wastewater tank 1100 so as to avoid the air continuing to fall and mix with the wastewater and waste to stir up the wastewater and waste.
  • this can effectively prevent the wastewater and waste in the wastewater tank 1100 from being sucked into the negative pressure source 1500, and not only can it avoid damage to the negative pressure source 1500 but also prevent wastewater and waste from being blown to the outside of the cleaning equipment so that the space utilization rate of the wastewater tank 1100 is increased. If the inner wall of the wastewater tank 1100 is not annular or circular, but other shapes, the collision of two or more air streams divided by the inlet blocker 1130 will be reduced, and the deposition of dirt cannot be achieved after the air streams enter the wastewater tank 1100.
  • the cleaning equipment includes the main body, a rotating device 2500, and a locking mechanism 2510.
  • the main body includes a machine body 1000 and a base 2000.

  • the adjustment of the rotation angle of the machine body 1000 can facilitate the extension of the base 2000 into a narrow space for cleaning operations and improve the cleaning efficiency in the narrow space.
  • the rotating device 2500 can form a fixed rotating axis through a structure such as a rotating shaft to make the machine body 1000 be rotatably assembled on the base 2000 through the rotating device 2500.
  • a rotating groove 2520 is defined on the base 2000, and the rotating device 2500 is rotatably assembled in the rotating groove 2520 through the rotation shaft.
  • the locking mechanism 2510 can lock the rotating device 2500 when the rotating device 2500 rotates to a preset rotation angle, so that the rotating device 2500 cannot continue to rotate at this rotation angle.
