Description

Technical Field

[0001] The utility model relates to a water tank for a cleaning robot, mainly relating to the field of cleaning tools. Background Art

[0002] With the development of technology and the improvement of living standards, the role played by restaurant service robots is becoming increasingly important. When a restaurant service robot cleans the garbage on the table, it often encounters large stains that are difficult to remove. At this time, the robot needs to issue a cleaning instruction to let the clear water pipe spray a certain amount of clear water onto the table first, and then let the sewage pipe recycle the sewage into the sewage tank.

[0003] In the prior art, after the restaurant service robot finishes working, the sewage in the sewage tank needs to be cleaned manually, which takes extra time and effort for maintenance. However, the sewage tank of this design can realize the self-cleaning function and can regularly clean the sewage tank, effectively reducing the growth of bacteria. Summary of the Utility Model

[0004] In view of the above deficiencies of the prior art, the utility model provides a water tank for a cleaning robot. A spray cavity is arranged at the inner top of the sewage tank, spray openings are arranged on the periphery of the spray cavity, and clear water is discharged from the spray openings, so that the inside of the sewage tank can be cleaned after cleaning the outer wall, avoiding the accumulation of stains in the sewage tank.

[0005] To achieve the above object, the technical solution of the utility model is: including a sewage tank, a suction fan and a clear water tank;

[0006] The upper part of the sewage tank is communicated with the cleaning device through a sewage inlet pipe, and the bottom of the sewage tank is communicated with the outside through a sewage discharge pipe;

[0007] The air inlet of the suction fan is communicated with the top of the sewage tank;

[0008] A spray cavity is arranged at the inner top of the sewage tank, spray openings are arranged on the periphery of the spray cavity, the spray cavity is communicated with the clear water tank through a clear water pipe, and a water pump is arranged on the clear water pipe.

[0009] The technical principle and beneficial effects of the utility model are as follows:

[0010] When in use, the suction fan provides negative pressure power for the sewage in the sewage pipe to enter the sewage tank. The sewage enters from the top of the sewage tank to avoid backflow. The air inlet of the suction fan is located at the top, which can also prevent water from entering the suction fan. The sewage discharge pipe is arranged at the bottom of the sewage tank to facilitate the complete discharge of stains. Among them, a spray cavity is arranged at the inner top of the sewage tank, spray openings are arranged on the periphery of the spray cavity, and clear water is discharged from the spray openings, so that the inside of the sewage tank can be cleaned after cleaning the outer wall, avoiding the accumulation of stains in the sewage tank.

[0011] Preferably, a lid is provided at the upper port of the sewage tank, and the suction fan is arranged on the lid. This can better fix the suction fan.

[0012] Preferably, a water baffle is provided in the sewage tank corresponding to the air inlet of the suction fan, and an air inlet window is arranged on the side of the air inlet of the suction fan and the water baffle. Through the water baffle, the air inlet is made more tortuous, which can prevent stains or large-volume impurities from entering the suction fan.

[0013] Preferably, a filtering device is arranged at the air inlet of the suction fan. This can prevent impurities from entering the suction fan.

[0014] Preferably, the spray chamber is fixed below the water baffle. This makes the spatial layout more reasonable and prevents the water coming out of the spray nozzles from entering the suction fan.

[0015] Preferably, the spray chamber includes an inner cavity and an annular outer cavity. The annular outer cavity is located on the periphery of the inner cavity, and communication holes are provided between the annular outer cavity and the inner cavity. The clear water pipe is connected to the inner cavity, and spray nozzles are arranged on the periphery of the annular outer cavity. Through the cooperation of the inner cavity and the annular outer cavity, water can be sprayed more evenly around.

[0016] Preferably, an air pressure balance pipe communicating with the outside is arranged in the sewage tank, and a valve is arranged on the air pressure balance pipe. This makes the internal and external pressures balanced and facilitates drainage more conveniently.

[0017] Preferably, the air pressure balance pipe is provided with a valve and extends upward from the bottom of the sewage tank to the upper part of the sewage tank. The air pressure balance pipe can also serve as a stress structure member of the sewage tank, and the overall strength is higher. BRIEF DESCRIPTION OF THE DRAWINGS
