Taking the base station as an example, in order to facilitate the use of a user, the base station is often matched with the use of the cleaning robot, the base station can be used for charging the cleaning robot, and when the electric quantity of the cleaning robot is less than a preset electric quantity threshold value in the cleaning process, the cleaning robot can move to the base station for charging. For the cleaning robot, the base station can also clean the mopping piece (such as a mop), and after the mopping piece of the cleaning robot mops the floor, the mopping piece often becomes dirty and needs to be cleaned. For this purpose, the base station can be used for cleaning the mop of the cleaning robot. Specifically, the cleaning robot may be moved to the base station so that the cleaning mechanism on the base station automatically cleans the cleaning robot's mop. Besides the functions, the base station can also be used for maintaining and managing the cleaning robot, so that the cleaning robot can be controlled more intelligently in the process of executing the cleaning task, and the working intelligence of the robot is improved.
In order to realize cleaning of the cleaning robot's cleaning elements, a waterway system is arranged in the base station, the waterway system comprises a clear water tank, and water at an external water supply end can be connected through a water inlet of the clear water tank, so that automatic water supplementing of the base station is realized; the water of the clean water tank can be transmitted to the area needing water through the waterway channel, for example, when the cleaning of the cleaning piece is needed, the clean water of the clean water tank can be transmitted to the cleaning area, and the cleaning area supplies water for the cleaning piece so as to clean the cleaning piece. The base station can perform maintenance and management such as mop washing and the like for the cleaning robot and can perform self-cleaning tasks, and the base station can perform self-cleaning on an internal cleaning area so as to clean stains accumulated in the cleaning area.

In practical application, if overflow condition takes place for water route or water tank in waterway system, then can influence cleaning equipment's influence, can cause the result of bubble water to cleaning equipment place even, consequently, this scheme is through taking the measure of tertiary anti-overflow to promote waterway system anti-overflow stability and reliability.
The invention provides an anti-overflow method of cleaning equipment, which is applied to the cleaning equipment, such as a base station, a cleaning robot, a handheld cleaning equipment and the like, wherein the cleaning equipment comprises a water tank and a waterway, and the waterway is respectively communicated with a water inlet of the water tank and an external water source, so that the external water source can flow into the water tank under the condition that the waterway and the water inlet are communicated, and the automatic water injection of the water tank is realized.
Wherein be equipped with the solenoid valve that is used for controlling the water route break-make on the water route, cleaning device is equipped with ball cock and first water level detection spare, and the ball cock is used for closing the water inlet when the water level in the water tank reaches first default, and first water level detection spare is used for triggering the overflow signal when the water level in the water tank reaches the second default, and the second default is greater than first default, also: the liquid level height when the float valve closes the water inlet is lower than the liquid level height when the first water level detection piece triggers the overflow signal.
Optionally, a pressure reducing valve is further arranged on the waterway, and the water pressure in the waterway is reduced through the pressure reducing valve, so that the pressure born by the waterway is reduced. Simultaneously, the solenoid valve is only opened when the water injection, when not the water injection, outside water source is cut off by the solenoid valve for the water route need not to bear the water pressure under this circumstances, thereby avoids the water route to bear the water pressure for a long time, can prolong the life of water route to a certain extent.
Further, the positions of the electromagnetic valve and the pressure reducing valve can be changed, and the electromagnetic valve can be arranged at the front end of the pressure reducing valve or at the rear end of the pressure reducing valve. When the electromagnetic valve is arranged at the front end of the pressure reducing valve, the electromagnetic valve is controlled to be opened first, so that an external water source is communicated with the waterway, and then the external water source is reduced in pressure through the pressure reducing valve. When the electromagnetic valve is arranged at the rear end of the pressure reducing valve, the external water source is firstly reduced in pressure through the pressure reducing valve, and then the electromagnetic valve is controlled to be opened, so that the reduced external water source flows into the water tank through the waterway and the water inlet in sequence.
Further, the solenoid valve and the pressure reducing valve may be integrated to form a pressure reducing solenoid valve.

In some embodiments, the float valve provided by the invention comprises a float ball, a pivot rotating shaft and a water stop valve, wherein the float ball and the water stop valve are respectively connected with the pivot rotating shaft, and the float ball drives the pivot rotating shaft to rotate through the buoyancy of water in the water tank, so that the water stop valve acts to close a water inlet of the water tank.
Referring to fig. 1, the cleaning device overflow prevention method provided by the invention includes:
step S10, after receiving the water injection signal, controlling the electromagnetic valve to be opened so that an external water source flows into the water tank through the waterway and the water inlet;
step S20, detecting whether the float valve closes the water inlet or not through a first water level detection part;
step S30, if not, closing the electromagnetic valve to end the water injection operation; and/or performing a water injection abnormality prompting operation.
In this embodiment, when the water injection signal is not received, the solenoid valve is in a normally closed state to intercept the external water source from the source, preventing the external water source from flowing into the water tank through the waterway and the water inlet. When the water injection signal is received, the electromagnetic valve is in an open state, so that an external water source flows into the water tank through the waterway and the water inlet, and automatic water injection of the water tank is realized.
When the float valve closes the water inlet of the water tank, the water tank is filled with water, but the condition that the float valve is abnormal is considered, so that whether the float valve closes the water inlet of the water tank is detected by the first water level detecting piece. If the first water level detecting piece detects that the floating ball valve does not close the water inlet, the floating ball valve can be confirmed to be abnormal, and in the case, the electromagnetic valve is controlled to be closed so as to cut off an external water source from the source, and the external water source is prevented from continuously flowing into the water tank, so that the water injection operation of the water tank is finished. According to the overflow prevention method for the cleaning equipment, which is provided by the invention, three-level overflow prevention protection for the water tank is realized through the electromagnetic valve, the ball float valve and the first water level detection part, so that the overflow condition of the water tank can be effectively avoided, and the functional reliability of the cleaning equipment can be greatly improved.
Optionally, when the first water level detecting member detects that the float valve does not close the water inlet, a water injection abnormality prompting operation may be performed, such as sending an audible and visual alarm signal to the outside to prompt the user of water injection abnormality. When the first water level detection part detects that the float valve does not close the water inlet, the electromagnetic valve can be controlled to be closed and water injection abnormality prompting operation can be executed at the same time, so that overflow situation can be avoided more reliably.
Wherein, the first water level detecting member may be at least one of: detection electrodes (e.g. anti-spill needle), time of flight TOF sensors, capacitive sensors, ultrasonic sensors, etc., by means of which at least one of the above mentioned sensors water level detection in the water tank can be performed.

and S22, if the first water level detection piece does not trigger the overflow signal within the preset duration range, determining that the float valve successfully closes the water inlet.
In this embodiment, when the water tank is filled with water, if the first water level detecting member triggers the overflow signal within the preset duration range, it indicates that the water level in the water tank reaches the second preset value, so that it can be determined that the float valve is abnormal. Namely: when the water level in the water tank reaches a first preset value, the ball float valve does not close the water inlet of the water tank, and after the water level in the water tank reaches the first preset value, an external water source still flows into the water tank through the waterway and the water inlet, so that water in the water tank overflows from the water inlet. Otherwise, if the first water level detection part does not trigger the overflow signal within the preset duration range, the normal operation of the float valve can be determined, and the water inlet of the water tank is successfully closed.
In some embodiments, the invention further comprises the steps of:
if the first water level detection part does not trigger the overflow signal within the preset duration range, but the first water level detection part triggers after the target time passes, the electromagnetic valve is closed to finish the water injection operation; and/or performing a water injection abnormality prompting operation.
In specific implementation, considering that the overflow exists but the overflow is slower, the first water level detection part is triggered after the overflow is longer than the preset time range, so if the first water level detection part does not trigger the overflow signal in the preset time range, but the first water level detection part triggers after the target time, the float valve and the electromagnetic valve are still determined to be failed at the same time or the first water level detection part fails to report by mistake. Wherein, to the condition that ball float valve and solenoid valve were lost efficacy simultaneously, the unusual suggestion operation of water injection can be carried out. For the fault condition of the water level sensor, the electromagnetic valve can be closed, and water injection abnormality prompting operation is executed; alternatively, the water injection abnormality prompting operation may be performed.
