The elastic device 323 can be a spring, a spring sheet, etc., and can drive the valve core 322 to close the valve cavity 320 by its own elastic action. During the process that the dirt in the slop pail 11 flows to the waste sink assembly 22 through the waste port 210, the valve core 322 closes the valve cavity 320 under the action of the elastic device 323, so that the dirt can be prevented from entering the valve cavity 320.

The opening and closing of the head assembly 32 is controlled by the water pressure in the water spray pipe 31. For example, when a water pump supplying liquid to the water discharge pipe 31 is turned on, the head assembly 32 is turned on by water pressure, and the head assembly 32 is turned off after the water pump is turned off.

In some embodiments of the present disclosure, the spout 31 has a first position extending into the interior of the dirt cup 11, a second position retracted within the base 2, and a third position between the first and second positions. The first position refers to a position where the water spray pipe 31 moves to the top dead center, that is, the water spray pipe 31 moves upward to the maximum stroke position, and the top end of the water spray pipe 31 is located at the top of the slop pail 11. For example, referring to the orientation of the view of FIG. 5, the spout 31 is at top dead center, where the spout 31 can no longer continue to extend upward. The second position refers to the position of the spout 31 moving to the bottom dead center, where the spout 31 cannot be further retracted downward, and the top end of the spout 31 is retracted into the waste port 210 and below the top edge of the waste port 210. By arranging the upper dead point and the lower dead point, the phenomenon that the movement range of the water spraying pipeline 31 is too large and the water spraying pipeline collides with the sewage bucket 11 or the structure of the base 2 can be prevented, and the water spraying pipeline 31, the sewage bucket 11 or the base 2 is prevented from being damaged.

The water jet pipe 31 also has a third position arranged between the first position and the second position, which third position refers to a position located at a distance above the second position, for example the third position may be 5mm higher than the second position. In one embodiment of the present disclosure, when the spout 31 is in the third position, the top end of the spout 31 is still below the top edge of the waste outlet 210.

In one embodiment of the present application, when the water spray pipe 31 is located at the second position, the top surface of the water spray pipe 31 is flush with the wall surface of the sewage chamber 220, and it can also be said that the top surface of the water spray pipe 31 forms a part of the wall surface of the sewage chamber 220.

Referring to fig. 16, a first detecting element 271 and a second detecting element 272 are provided in the base, and the first detecting element 271 is configured to be triggered when the water spray pipe 31 moves to the first position. The water spraying pipe 31 may be provided with a trigger portion for triggering the first detecting element 271 and the second detecting element 272, and the trigger portion may be a flange structure or a lever structure. The position of first sensing element 271 within the base is such that when spout 31 is moved to the first position, first sensing element 271 is triggered to issue a control signal which is sent to a control unit which can be used to signal that spout 31 reaches the first position, and based on the control signal, the control unit can control spout 31 to stop moving or perform other corresponding controls to prevent damage to base station 2 caused by continued extension.

The position of the second detecting element 272 in the base 2 is such that when the water spray pipe 31 is moved to the second position, the second detecting element 272 is triggered to send out a control signal. When second sensing element 272 is triggered, a signal indicating that sprinkler pipe 31 reaches the second position may be sent to the control unit, and the control unit may control sprinkler pipe 31 to stop moving or perform other corresponding control based on the signal. The first and second detecting

elements

271 and 272 of the present disclosure may be switches for detecting a stroke, such as a micro switch and a limit switch, or may be a switch type known to those skilled in the art, which is not limited thereto.

In one embodiment of the present disclosure, the control unit is configured to control the sprinkler pipe 31 to move in reverse to the third position for docking based on an electrical signal triggering the second detection element when the sprinkler pipe 31 moves to the second position. In the disclosed embodiment, the spout 31 needs to be retracted into the base 2 after it is washed in the waste tub 11. In this case, the control unit controls the movement of the water jet pipe 31 from the first position in the direction of the second position. After the sprinkler pipe 31 moves to the second position and triggers the second detecting element 272, the control unit may control the sprinkler pipe 31 to move reversely to the third position to stop based on the electric signal triggered by the second detecting element 272. That is, the spout 31 will be oriented in the first position until it is moved to a third position for docking.

This is because the second position of the present disclosure is the trigger position of the second detection element 272, and when a pressure-triggered switch such as a micro switch or a limit switch is used, if the switch is in a pressed state for a long time, the switch may be out of order, and therefore, the water spray pipe 31 needs to be stopped at a third position higher than the second position to protect the second detection element 272.

Referring to fig. 17, when the water spray pipe 31 moves to point B, the second detecting element 272 triggers an electrical signal indicating that the water spray pipe 31 moves to the second position, where the first position is denoted as a, the second position is denoted as B, and the third position is denoted as C, as indicated by D1 in fig. 17. Referring to the schematic position of D2, the control unit controls the sprinkler pipe 31 to move reversely to point C based on the electrical signal triggered by the second detecting element 272, so that the bottom of the sprinkler pipe 31 is away from the second detecting element 272. Thereby, the second detection element 272 is kept in an unfired state.

In the cleaning system of the present disclosure, the water jet 31 is always stopped in the third position C. In some embodiments of the present disclosure, before the triggering mechanism 23 opens the sealing assembly 111, the control unit is configured to control the water spraying pipe 31 to move from the third position to the second position, and then the second detecting element 272 triggers the electric signal of the water spraying pipe 31 moving to the second position, and the control unit controls the water spraying pipe 31 to stay at the second position according to the electric signal of the second detecting element 272. This application scenario is where the trigger mechanism 23 needs to open the sealing assembly 111 to discharge the waste water from the waste tub 11, and since the water spray pipe 31 is moved upward relative to the second position by a predetermined distance to reach the third position, the dirt in the waste tub 11 may adhere to or wrap around the top area of the water spray pipe 31. Based on this, in the process of opening the sealing assembly 111 to discharge the sewage, the water spraying pipe 31 needs to be lowered and moved to the second position. In the process, after the water spraying pipe 31 moves to the second position and triggers the second detecting element 272, the electric signal triggered by the second detecting element 272 can be used as a control signal for stopping the movement of the water spraying pipe 31.

After the sewage in the slop pail 11 is discharged, the inner cavity of the slop pail 11 needs to be cleaned. With continued reference to fig. 17, in some embodiments of the present disclosure, the control unit is configured to control the movement of spout pipe 31 from the second position to the first position to spray liquid against the inner wall of slop pail 11 based on the wash instruction. For example, referring to the schematic positions D1 to D3 in fig. 17, the top end of the water spraying pipe 31 starts to move from the second position B to the first position a, at this time, the first detecting element 271 triggers and sends out an electric signal for indicating that the water spraying pipe 31 moves to the start cleaning position, and the control unit controls the water spraying pipe 31 to start spraying water based on the electric signal sent by the first detecting element 271. During the spraying of water, the control unit may control the reciprocating motion of the water spray pipe 31 in the inner cavity of the slop pail 11 based on time or other parameters to achieve full cleaning of the slop pail 11.

When the washing of the waste water tank is finished, the water spraying pipe 31 moves from the first position a to the second position B, and after the second detecting element 272 is triggered, the control unit controls the water spraying pipe 31 to move reversely to the third position C based on the triggered electric signal and stay at the third position C.

The present disclosure also provides a base station for placing a cleaning device, which may be a hand-held floor washing machine, a cleaning robot, or the like. The base station comprises a base 20 and a docking platform 21 arranged on the base 20, wherein a sewage outlet 210 for docking with the sewage outlet 110 of the cleaning device 1 is arranged on the docking platform 21. The base 20 is provided with a washing mechanism 3, and the washing mechanism 3 comprises a water spraying pipeline 31; the flushing mechanism 3 is configured to be able to extend the water jet pipe 31 through the sewage outlet 110 into the sewage bucket 11 of the cleaning device 1; the liquid in the water spray pipe 31 is configured to be sprayed to the inner wall of the slop pail 11 through the water outlet provided on the water spray pipe 31, so as to clean the inner wall of the slop pail 11, without the need for the user to manually clean the slop pail 11, thereby improving the user experience. The specific structure, principle, etc. of the base station can be referred to the above cleaning system, and therefore, the detailed description thereof is omitted in this disclosure.

The disclosure also provides a control method of the cleaning system, and the cleaning system comprises the following steps:

step one, the cleaning device 1 is placed on the base station 2, and the sewage outlet 110 of the sewage bucket 11 in the cleaning device 1 is butted with the sewage outlet 210 on the butting platform 21.

A trigger mechanism 23 on the base 20 can control the sealing assembly 111 to open or close the waste outlet 110. When the sealing assembly 111 is opened, the dirt in the inner cavity of the slop pail 11 can be discharged through the dirt discharge opening 110 and the dirt discharge opening 210 into the dirt discharge chute assembly 22 of the base 20.

And step two, controlling the water spraying pipeline 31 in the flushing mechanism 3 to extend into the inner cavity of the sewage bucket 11 through the sewage port 210 and the sewage outlet 110.

The flushing mechanism 3 is disposed in the base 20 and includes a water jetting pipe 31 and a moving mechanism 34 that drives the water jetting pipe 31 to extend or retract. When the cleaning device 1 is docked with the base station 2, the water spraying pipe 31 is located below the sewage outlet 110, the water spraying pipe 31 is driven by the moving mechanism 34 to extend upwards, the water spraying pipe 31 can extend out of the sewage port 210, and then the water can enter the inner cavity of the sewage bucket 11 through the sewage outlet 110 docked with the sewage port 210.

And step three, controlling the water spraying pipeline 31 to spray water to the inner wall of the sewage bucket 11 so as to clean the inner wall of the sewage bucket 11.

The water spraying pipe 31 is connected with a hose for supplying water, and the water outlet of the water spraying pipe 31 is positioned at one end extending into the slop pail 11 and can spray water to the slop pail 11. The nozzle assembly 32 is arranged at the water outlet, and the valve core 322 of the nozzle assembly 32 is in a closed state under the action of the spring, so that the dirt discharged from the sewage bucket through the sewage outlet 110 and the sewage outlet 210 is prevented from entering the nozzle assembly 32. The valve element 322 of the spray head assembly 32 can be opened under the hydraulic pressure to spray water to the inner wall of the slop pail 11, so as to wash away the dirt attached to the inner wall of the slop pail 11. The cleaned liquid can enter the sewage port 210 through a gap between the sewage drain 110 and the water spray pipe 31.

In detail, the above control method is controlled by a control unit of the cleaning system. When the cleaning device 1 is placed on the base station 2, the control unit can control the trigger mechanism 23 on the base 20 to open the sealing assembly 111 on the sewage discharge outlet 110 based on the self-cleaning instruction, so that the sewage in the sewage bucket 11 enters the sewage discharge tank assembly 22 through the sewage discharge outlet 110 and the sewage outlet 210.
