Description

Base station for sewage system and floor scrubber

Technical Field

The utility model relates to the technical field of floor washing systems, in particular to a sewage discharge system and a base station of a floor washing machine.

Background technique

A floor scrubber is a device for cleaning the floor. When the floor scrubber is working, clean water is supplied from the clean water tank to the roller brush. The roller brush rotates and wipes the floor under the action of the motor, so that the dirt is quickly separated from the floor and mixed with clean water to become sewage. At this time, the first sewage tank becomes a vacuum state under the operation of the vacuum motor, allowing the sewage to be recovered to the first sewage tank through the sewage suction pipe. After the floor scrubber completes the cleaning work and returns to the base station, the retractable trigger part set on the base station is used to discharge the sewage in the sewage barrel to achieve sewage discharge.

However, since sewage may contain a certain volume of dirt, the existing floor scrubber base station may easily clog the pipe after discharging sewage.

In order to solve the above problems, it is urgent to provide a sewage discharge system and a base station of a floor scrubber to solve the problem of pipe blockage during the sewage discharge process.

Embodiment 1

As shown in FIG1 , the present embodiment provides a base station of a floor scrubber 3000. At present, the commonly used floor scrubber 3000 includes a cleaning part, a battery pack 3600, a main fan 3500, and a handle 3700. When working, the user operates the handle 3700, the battery pack 3600 is electrically connected to the main fan 3500, the cleaning part is connected to the main fan 3500, the battery pack 3600 provides power to the main fan 3500, and the main fan 3500 drives the cleaning part to rotate and wipe the ground after the movement, so that the dirt is quickly separated from the ground. Further, the floor scrubber 3000 also includes a clean water outlet 3300, a sewage outlet 3100, a clean water tank 3400, and a second sewage tank 3200. Before the floor scrubber 3000 works, clean water needs to be injected into the clean water tank 3400 connected to the clean water interface, and the clean water can be transported to the cleaning part when the floor scrubber 3000 works, so that the cleaning part works in a wet state, which is conducive to improving the cleaning effect. The garbage separated from the ground by the cleaning element is mixed with clean water to form sewage. Under the operation of the vacuum motor, the second sewage tank 3200 becomes a vacuum state, allowing the sewage to be recovered to the second sewage tank 3200 through the sewage suction pipe and can be recovered in the second sewage tank 3200.

The floor scrubber 3000 that has completed its work is placed on the base station of the floor scrubber 3000, and the clean water outlet 3300 of the floor scrubber 3000 can be connected to a faucet or a box on the base station for containing clean water, so that the floor scrubber 3000 is replenished with clean water in time for the next use.

Please continue to refer to FIG. 1 . Meanwhile, the present embodiment further provides a sewage discharge system 1000 disposed on the base station. When the floor scrubber 3000 is placed on the base station, the sewage discharge system 1000 is connected between the sewer pipe 2000 and the sewage outlet 3100 of the floor scrubber 3000. The sewage discharge system 1000 includes a sewage discharge mechanism 100 and a pressure mechanism 200. The sewage discharge mechanism 100 can discharge the sewage in the floor scrubber 3000 into the first sewage tank 110 of the sewage discharge mechanism 100 or the sewer pipe 2000. The pressure mechanism 200 can be connected to the sewer pipe 2000. The pressure mechanism 200 is used to release high-pressure gas into the sewer pipe 2000. The pressure mechanism 200 discharges sewage at high pressure or clears the sewer pipe 2000 at high pressure. Even if there are large particles of garbage in the first sewage tank 110, the pressure mechanism 200 can still flush them out to avoid blockage of the sewer pipe 2000. The sewage discharge system 1000 is helpful to improve the user experience of using the base station.

Optionally, the pressure mechanism 200 includes a pressure assembly 210 and a first valve body 220. The pressure assembly 210 is used to generate high-pressure gas, the first valve body 220 is signal-connected to the pressure assembly 210, and the first valve body 220 is connected between the pressure assembly 210 and the sewer pipe 2000. When the air pressure in the pressure assembly 210 reaches a preset threshold, the first valve body 220 opens to release the high-pressure gas to dredge the sewer pipe 2000.

The pressure assembly 210 includes a pressure fan 211 and a pressure chamber 212. The pressure fan 211 is provided with an air inlet 2111, and the pressure chamber 212 is connected to the pressure fan 211. The pressure fan 211 can rush the gas entering from the air inlet 2111 into the pressure chamber 212, so that the gas converges in the pressure chamber 212 to reach a preset threshold.

The pressure assembly 210 further includes a detection member 213 , which is used to detect the air pressure in the pressure chamber 212 , so that the base station can timely monitor the air pressure in the pressure chamber 212 , which is beneficial to ensuring the safety of the pressure assembly 210 .

The sewage discharge mechanism 100 includes a first sewage tank 110, a sewage discharge fan 120 and a second valve body 130. The first sewage tank 110 is arranged above the sewer pipe 2000, and the first sewage tank 110 is connected to the sewer pipe 2000. The sewage discharge fan 120 is located on one side of the first sewage tank 110. The second valve body 130 is arranged between the sewage discharge fan 120 and the first sewage tank 110. The second valve body 130 controls the sewage discharge fan 120 and the first sewage tank 110 to be connected or disconnected. When the second solenoid valve is opened, the sewage discharge fan 120 moves to generate negative pressure, thereby sucking the sewage and large particles of garbage in the second sewage tank 3200 of the scrubber 3000 into the first sewage tank 110 of the base station. At this time, under the action of gravity and water flow, the garbage will be flushed into the sewer pipe 2000.

At this time, large particles of garbage may block the sewer pipe 2000. In order to avoid this situation, the pressure fan 211 is started to allow gas to enter the pressure chamber 212 from the air inlet 2111. When the detection member 213 detects that the pressure value in the pressure chamber 212 reaches a preset threshold, the first valve body 220 opens to release the high-pressure gas in the pressure chamber 212, and the high-pressure gas is filled into the sewer pipe 2000, thereby transporting the garbage still remaining in the sewer pipe 2000 to avoid blockage of the sewer pipe 2000.

Furthermore, in order to prevent the sewage or odor in the first sewage tank 110 or the sewer pipe 2000 from flowing back, a one-way valve 300 is provided at the inlet where the base station communicates with the sewage outlet 3100 of the floor scrubber 3000 .

Embodiment 2

This embodiment provides a sewage system 1000, and the structure of the sewage system 1000 is basically the same as that of the sewage system 1000 in the first embodiment. In order to avoid redundancy, this embodiment only describes the differences.

As shown in Fig. 2 and Fig. 3, in this embodiment, the pressure mechanism 200 is further provided with a driving assembly 230 on the basis of the pressure assembly 210 and the first valve body 220. The driving assembly 230 is connected to the pressure assembly 210, and the driving assembly 230 is configured to make the pressure assembly 210 and the sewer pipe 2000 sealed or non-sealed. The first valve body 220 is connected to the pressure assembly 210 by signal, and the first valve body 220 is arranged between the pressure assembly 210 and the driving assembly 230. When the driving assembly 230 is sealed and connected to the sewer pipe 2000, if the air pressure in the pressure assembly 210 reaches a preset threshold, the first valve body 220 opens to release the high-pressure gas. The pressure mechanism 200 directly connects the pressure assembly 210 and the sewer pipe 2000 through the driving assembly 230, which is conducive to transporting the high-pressure gas of the pressure assembly 210 to the sewer pipe 2000 as much as possible, thereby increasing the pressure of the gas released into the sewer pipe 2000.

The structures of the pressure fan 211, the pressure chamber 212 and the detection member 213 of the pressure assembly 210 in this embodiment are the same as those in the first embodiment and will not be described again here.

Optionally, in this embodiment, the sewage discharge mechanism 100 only includes the sewage discharge fan 120, and the second valve body 130 and the first sewage tank 110 may not be provided, thereby simplifying the structure of the sewage discharge mechanism 100. As shown in FIG2, when the floor scrubber 3000 is connected to the base station, the movable pipe 232 is located away from the sewer pipe 2000, and the sewage discharge fan 120 moves to generate negative pressure, thereby sucking the sewage and large particles of garbage in the second sewage tank 3200 of the floor scrubber 3000 into the base station, and directly flushing into the sewer pipe 2000 under the action of gravity and water flow. Of course, if the sewage discharge mechanism 100 can also be provided with the first sewage tank 110 and the second valve body 130, the structure is the same as that of the sewage discharge mechanism 100 in the first embodiment, and it will not be repeated here.

Furthermore, the driving assembly 230 includes a connecting pipe 231, a movable pipe 232 and a driving member 233. One end of the connecting pipe 231 is connected to the pressure assembly 210, and the first valve body 220 is located between the pressure assembly 210 and the connecting pipe 231, so as to control the communication between the pressure chamber 212 and the connecting pipe 231 by using the first valve body 220. The movable pipe 232 is sleeved on the connecting pipe 231, and the end of the movable pipe 232 away from the pressure assembly 210 can be sealed or non-sealed connected to the sewer pipe 2000. Since the gas is transported from the pressure chamber 212 to the connecting pipe 231, the movable pipe 232 is sleeved on the connecting pipe 231, which can reduce the leakage of the gas in the connecting pipe 231 and the movable pipe 232, thereby further ensuring that a higher proportion of the gas enters the sewer pipe 2000. The driving member 233 is used to drive the movable pipe 232 to reciprocate along its axial direction, so that the movable pipe 232 is sealedly connected or unsealedly connected to the sewer pipe 2000.

As shown in FIG2 , since sewage and large particles of garbage are directly discharged into the sewer pipe 2000, the sewer pipe 2000 may be blocked. In order to avoid this situation, after the sewage discharge mechanism 100 discharges sewage, the pressure fan 211 is started, so that the gas enters the pressure chamber 212 from the air inlet 2111 and accumulates. At the same time, as shown in FIG3 , the driving member 233 drives the movable pipe 232 to approach the sewer pipe 2000, so that the movable pipe 232 is sealed and connected with the sewer pipe 2000. At this time, one end of the movable pipe 232 close to the sewer pipe 2000 abuts against the inner wall or end face of the sewer pipe 2000. When the detection member 213 detects that the pressure value in the pressure chamber 212 reaches a preset threshold, the first valve body 220 opens to release the high-pressure gas in the pressure chamber 212, and the high-pressure gas is filled into the sewer pipe 2000, thereby transporting the garbage still remaining in the sewer pipe 2000 and avoiding the blockage of the sewer pipe 2000.

In addition, when the pressure component 210 is non-sealedly connected to the sewer pipe 2000, the end of the driving component 230 away from the pressure component 210 is away from the sewer pipe 2000 to connect the sewage mechanism 100 with the sewer pipe 2000, so as to ensure that the sewer pipe 2000 can be connected with the sewage outlet of the floor scrubber 3000, so as to facilitate the next sewage discharge operation.

As an optional solution, the movable tube 232 includes a tube body 2321 and a rack 2322. The rack 2322 is arranged on the outer wall of the tube body 2321 along the axial direction of the tube body 2321. The driving member 233 is a gear, which meshes with the rack 2322, thereby driving the tube body 2321 to move in a direction close to or away from the sewer pipe 2000. The structure is simple and easy to implement.

In addition, in order to ensure the sealing effect of the movable tube 232 abutting against the inner wall or end face of the sewer pipe 2000, the movable tube 232 also includes a sealing portion 2323 arranged at one end of the tube body 2321 away from the pressure assembly 210. When the movable tube 232 is sealed and connected to the sewer pipe 2000, the sealing portion 2323 abuts against the inner wall or end face of the sewer pipe 2000. Further, the sealing portion 2323 is trumpet-shaped, so that when the diameter of the movable tube 232 is smaller than that of the sewer pipe 2000, it can still be sealed and connected to the sewer pipe 2000. Through the arrangement of the above-mentioned sealing portion 2323, the diameter of the movable tube 232 in this embodiment is smaller than that of the sewer pipe 2000. The use of the movable tube 232 with a small diameter is conducive to further gathering the pressure released from the pressure chamber 212, so as to increase the pressure when the high-pressure gas is released into the sewer pipe 2000, thereby improving the effect of clearing the sewer pipe 2000.

Note that the above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected, and the scope of protection of the utility model is defined by the attached claims and their equivalents.
