I.e. when the valve is in an open state, the valve may communicate the blocking means 3 to the outside atmosphere, thereby communicating the pipe system 2 to the outside atmosphere, whereby the siphon effect between the pipe system 2 and the tank 1 may be cut off. When the valve is in the closed state, the scrubber 100 can work normally, and the liquid in the tank 1 can be led via the pipe system 2 to the cleaning cloth 9 in the scrubber 100 or to the surface to be cleaned for cleaning, i.e. when the scrubber 100 is in the floor washing state, the valve of the blocking device 3 is in the closed state. It will be appreciated that the valve may be a gas valve, a solenoid valve or other motor or non-motor driven valve, etc., so long as it is operable to communicate the pipe system 2 with the outside atmosphere.

In some embodiments, scrubber 100 further comprises a vent pipe 5, and vent pipe 5 is in communication with pipe system 2 and blocking device 3. Wherein, the communication position of the vent pipe 5 and the pipeline system 2 is a collecting position 4, and the blocking device 3 is arranged on the vent pipe 5 and is higher than the collecting position 4.

For example, the blocking device 3 may be a three-way valve, two ports of which are respectively connected to the first communicating pipe 21 and the second communicating pipe 22, and the other port of which is used for communicating with the external atmosphere. At this time, the convergence position 4 is a communication position between the first communication pipe 21 and the second communication pipe 22, and the position of the valve element at the other port is higher than the connection position between the first communication pipe 21 and the second communication pipe 22, that is, the height of the communication port of the valve element with the external atmosphere is higher than the height of the convergence position 4.

Referring to fig. 2 and 4, fig. 4 is a partially enlarged schematic structural diagram of a portion of fig. 2.

In some embodiments, the scrubber 100 further comprises a power unit 6 and a cleaning cloth 9, wherein the power unit 6 is connected to the pipe system 2 for providing power for the flow of the liquid, continuously absorbing the water, and pressurizing the water, so that the liquid in the tank 1 can flow out under the action of the power unit 6 and be delivered to the cleaning cloth 9 through the pipe system 2.

It will be appreciated that the power plant 6 may be located downstream of the collection location 4, and that the power plant 6 may be in communication with the pipe system 2 via a second communication pipe 22. The power device 6 may be a pump, and may be disposed at the end of the second communication pipe 22 or in the middle of the second communication pipe 22.

In some specific embodiments, the power means 6 is located below the tank 1. I.e. when the scrubber 100 is placed vertically, the height of the power unit 6 in the vertical direction is lower than the height of the tank 1, the height of the power unit 6 is lower than the height of the collecting position 4 and the height of the blocking device 3. Therefore, the power device 6 at the low position not only can provide power for the liquid in the pipeline system 2 to facilitate the extraction of the liquid, but also can reduce the energy consumption of the power device 6 by utilizing the height difference.

In some more specific embodiments, the blocking device 3, the reservoir 1, and the power device 6 are linearly arranged. Namely, the blocking device 3, the liquid storage tank 1 and the power device 6 are sequentially arranged from high to low in the vertical direction. Thereby, the size of the scrubber 100 can be reduced in a lateral direction.

To facilitate the arrangement of the power plant 6 throughout the scrubber 100, in some more specific embodiments the scrubber 100 further comprises a third communicating pipe 7 for conveying liquid conveyed by the pipe system 2 to the cleaning cloth 9 in the scrubber 100.

The third communicating pipe 7 is connected with the power device 6, and the power device 6 is connected with the pipeline system 2. Therefore, the water in the pipeline system 2 is pumped to the cleaning cloth 9 in the floor cleaning machine 100 by the power device 6 and the third communicating pipe 7, and liquid is conveyed by the third communicating pipe 7, so that the arrangement of the power device 6 in the floor cleaning machine 100 is facilitated, and the structure arrangement of the cleaning cloth 9 and the replacement of pipelines are facilitated. Referring to fig. 1, it can be understood that, in order to facilitate the liquid in the third communicating pipe 7 to be uniformly distributed on the cleaning cloth 9, a plurality of water outlets 8 may be further disposed between the third communicating pipe 7 and the cleaning cloth 9, the water outlets 8 are communicated with the third communicating pipe 7, the water outlets 8 are disposed in plurality, the plurality of water outlets 8 are axially spaced along the cleaning cloth 9, and the liquid in the third communicating pipe 7 can be uniformly distributed on the cleaning cloth 9 through the water outlets 8 to fully wet the cleaning cloth 9.

In order to facilitate the operation of the cut-off device 3 to be controlled intelligently by the operator, either manually or by the scrubber based on the detection signal, the scrubber 100 in some embodiments further comprises a control device for controlling the operation of the cut-off device 3.

In some specific embodiments, the control means are arranged for controlling the power means 6 to be closed and for controlling the shut-off means 3 to be opened simultaneously with or after controlling the power means 6 to be closed, in order to vent the pipe system 2 to the outside atmosphere. In an application scenario, after the floor washing machine 100 works in a floor washing mode, the control device can control the power device 6 to be closed and simultaneously or later control the blocking device 3 to be opened after receiving a control command of an operator; it is also possible to control the opening of the blocking device 3 according to a sensing device provided in the floor washing machine 100 after detecting that the floor washing machine 100 has finished and stopped working for a certain period of time. This allows the siphon effect between the pipe system 2 and the tank 1 to be blocked after opening the blocking device 3. It will be appreciated that after the shut-off device 3 is opened, liquid remaining in the first communication pipe 21 may flow into the tank 1 under the influence of atmospheric pressure after the shut-off device 3 is in communication with the outside atmosphere.

In a more specific embodiment the control means are further arranged to re-activate the power means 6 after opening of the control blocking means 3, so that the control means not only control the activation of the blocking means 3 but also re-activate the power means 6 when blocking the siphon effect between the pipe system 2 and the tank 1. That is to say, the control device is used to control the shut-off device 3 to open in order to vent the pipe system 2 to the outside atmosphere, and the control device is also used to control the power device 6 to deliver the liquid in the pipe system 2 downstream of the collection point 4 to the cleaning cloth 9 after the shut-off device 3 has been opened. It can be understood that the starting of the power device 6 is after the blocking device 3 is started, water remaining in the pipeline system 2 is extracted by the power device 6, so that liquid leakage caused by liquid remaining in the pipeline system 2 can be avoided, and liquid in the pipeline can be prevented from being frozen when bacteria grow or the temperature is too low. And the use of the power means 6 also saves the time for the discharge of residual liquid. It will be appreciated that the power of the power plant 6 when performing a floor wash is greater than the power of the power plant 6 when performing a siphon break.

In order to allow the operator to know whether the water remaining in the pipe system 2 has been completely discharged or to allow more control of the operation time when the liquid remaining in the pipe system 2 is discharged, in some embodiments, a flow meter is further provided on the third communicating pipe 7. Wherein the flow meter is connectable to the control device. It will be appreciated that the volume of the flow path through which liquid from the reservoir 1 is drawn into the cleaning cloth 9 can be calculated and therefore a flow value can be preset in the control means which automatically controls the shut-off of the power means 6 and the shut-off of the shut-off means 3 when the power means 6 is operating in the process of breaking the siphon effect after receiving the preset value for the liquid drawn by the power means 6.
