Description

Workstation with outward-drawable sewage tank

Technical Field

The utility model relates to the field of manufacturing of mobile cleaning equipment, in particular to a workstation matched with a mobile terminal, and particularly relates to a workstation with a sewage tank.

Background

In recent years, with the development of economy and the improvement of living standard, the cleaning mode of families and public places (such as markets, airports and high-speed rail stations) is gradually changed from manual to mechanical and intelligent. The advent of mobile cleaning equipment (e.g., hand-propelled sweeper/scrubber, automatic sweeper/scrubber, multi-functional automatic cleaning robots) may partially or fully free up human labor. Existing mobile cleaning devices generally include a mobile end and a workstation. The workstation has the functions of automatically charging, automatically adding water, automatically discharging sewage and the like for the mobile terminal.

Some common workstations have a tank secured in an outer housing (i.e., a stationary tank) for storing the sewage collected by the mobile terminal. After the sewage in the sewage tank is accumulated to a certain amount, the sewage is discharged once by adopting a pipeline (for example, the sewage in the sewage tank is pumped out once by adopting a pump and a drain pipe). The sewage can be stored in the sewage tank for a period of time, which is easy to cause the problems of precipitation of dirt, odor generation and the like. However, the fixed type sewage tank is difficult to clean, and a user needs to disassemble the outer shell of the whole workstation first, detach the sewage tank for cleaning and then replace the sewage tank, which is time-consuming and laborious.

Wherein the sewage tank 20 and the limiting part 30 are disposed in the housing 10. The bottom of the sewage tank 20 has a recessed area 20a. The stopper 30 is movable between a first position and a second position within the housing 10. When the stopper 30 is in the first position, at least a part of itself is positioned in the recessed area 20a, and the sewage tank 20 cannot move from the opening to the outside of the housing 10. When the stopper 30 is in the second position, it is separated from the recess area 20a, and the sewage tank 20 can move from the opening to the outside of the housing 10.

It should be understood by those skilled in the art that in the automatic sewage discharging mode, sewage in the sewage tank 20 may be automatically discharged through another pump and a drain line (e.g., a water pump 50 and a first drain line 50a described later), and the residual sewage generally stays in the recessed area 20a, thereby ensuring that the residual sewage is minimized, and sewage sediment is concentrated in the recessed area 20a even if the sewage tank 20 is not cleaned for a long time, so that the sewage tank 20 is conveniently pulled out for washing and discharging. In addition, the limiting part 30 is matched with the concave area 20a to limit the movement of the sewage tank 20, so that the situation that the sewage tank 20 is pulled out by misoperation of an operator, and the movable end of the movable cleaning device spills to the ground when the sewage is discharged to the workstation 100 can be prevented. Furthermore, after the sewage tank 20 moves from the opening to the outside of the casing 10, the sewage tank 20 can be cleaned (for example, a water gun equipped in a workstation or an externally connected water pipe or water gun is adopted for flushing), so that bacterial proliferation in the sewage tank 20 is effectively inhibited, and odor is prevented.

Further, the workstation 100 includes a pressing portion 40 disposed on the housing 10, the pressing portion 40 is associated with the limiting portion 30, and touching the pressing portion 40 can switch the limiting portion 30 between the first position and the second position.

In the present embodiment, the pressing portion 40 is represented as a handle-shaped member provided outside the housing 10, and the switching of the stopper portion 30 between the first position and the second position can be achieved by pressing (pushing and pulling) downward (or upward). Wherein the first position is represented by the low position shown in fig. 2 and the second position is represented by the high position shown in fig. 4.

Further, the workstation 100 includes a water pump 50 and a first drain pipeline 50a disposed on the limiting portion 30, and when the limiting portion 30 is at the first position, the water pump 50 is located in the recessed area 20a.

Further, the workstation 100 includes a liquid level sensor 60 (or a liquid level switch) disposed on the limiting portion 30, and after the liquid level sensor 60 obtains the liquid level in the sewage tank 20 to reach the preset height, the water pump 50 is turned on, and the sewage in the sewage tank 20 is discharged outwards through the first drainage pipeline 50 a. In this embodiment, the limiting portion 30 is a sheet metal frame that can move up and down, and the water pump 50, the first drain pipeline 50a, and the liquid level sensor 60 can all be disposed on the sheet metal frame. Wherein, the water pump 50 is located at the lowest end of the sheet metal frame, the liquid level sensor 60 is vertically arranged along the height direction of the sheet metal frame, and when the liquid level in the sewage tank 20 reaches the preset height, the control system receives the electric signal sent by the liquid level sensor 60 and controls the water pump 50 to be started, and the sewage is pumped out through the first drainage pipeline 50 a.

It should be understood by those skilled in the art that by providing the water pump 50 and the liquid level sensor 60 (or liquid level switch), the workstation 100 provided by the utility model can automatically identify the sewage level in the sewage tank 20, thereby controlling the water pump 50 to work, realizing automatic sewage discharge, and freeing up human resources occupied in the sewage discharge process. The water pump 50, the first drain line 50a, and the liquid level sensor 60 are integrally provided on the stopper 30. When the stopper 30 is in the first position, at least a part of itself is positioned in the recessed area 20a, and the sewage tank 20 cannot move from the opening to the outside of the housing 10 (the movement of the sewage tank 20 is further restricted by the presence of the water pump 50). At this time, the water pump 50 is also disposed in the recess area 20a in order to discharge sewage as much as possible during the automatic sewage discharge of the workstation 100, thereby minimizing the residual sewage in the sewage tank 20.

Further, the recess area 20a is located at a side of the sewage tank 20 adjacent to the opening.

Further, when the limiting part 30 is at the second position, the whole recessed area 20a of the sewage tank 20 can be moved to the outside of the housing 10 from the opening.

It should be understood by those skilled in the art that the entire recessed area 20a of the sewage tank 20 can be moved to the outside of the housing 10 through the opening, which is more advantageous for thoroughly cleaning the recessed area 20a in the case of direct visual observation, and whether it is completely washed or not is also clear.

Further, a drain port is provided in the recessed area 20a.

Further, a second drain pipe 20b is connected to the outside of the drain port.
