Based on the above setting: under the condition that the valve element 32 is communicated with the first water inlet pipe nozzle 322 and the water stored in the water storage component 21 is introduced into the water using component 22, the sweeping robot 2 presses the first press switch 331 to trigger a first press condition, so that the first electromagnetic structure 326 is electrified and magnetized, and the magnetic valve core 325 is attracted to slide leftwards to a first on position; in the case that the valve element 32 is communicated with the second water inlet pipe 323 and water from the external water source is introduced into the water using member 22, the sweeping robot 2 presses the second push switch 332 to trigger the second pressing condition, and the second electromagnetic structure 327 is energized to be magnetized and attracts the magnetic valve core 325 to slide rightward to the second on position.

Further, the closing manner of the valve element 32 after being triggered to be in the on state is not limited, for example, in the case that the valve element 32 is triggered to be in the on state of the first water inlet nozzle 322 or the second water inlet nozzle 323, the valve element 32 may be closed by powering off and demagnetizing the first electromagnetic structure 326 or the second electromagnetic structure 327 after the water member 22 reaches the set water inlet time/set water inlet amount, or the valve element 32 may be closed by powering off and demagnetizing the first electromagnetic structure 326 or the second electromagnetic structure 327 after the floor scrubbing member is cleaned to the desired cleaning effect (for example, in the case that the floor scrubbing member is cleaned while sewage is being supplied with water, the degree of contamination of the discharged sewage may be detected, and it is determined that the floor scrubbing member reaches the desired cleaning effect when the turbidity of the sewage is not higher than the set standard).

In the first preferred embodiment, the electromagnetic device and the pressing structure are divided into two sets of triggering systems so as to correspond to different on-states of the triggering valve 32, so that the first pressing state and the second pressing state can be respectively simplified into the same pressing triggering action, different pressing states are limited only by different pressing objects, the sweeping robot 2 has low execution difficulty when executing the triggering action, and the triggering, on-off and other control logics of each set of triggering components are simple.

Preferably, the pressing ends of the first pressing switch 331 and the second pressing switch 332 are both provided with a rotatable roller 333, and the sweeping robot 2 can apply pressure to the first pressing switch 331 or the second pressing switch 332 through the pressing roller 333, so that the form of the friction force between the sweeping robot 2 and the pressing switches is converted from sliding friction to rolling friction, the friction force is reduced, and the robot 2 is prevented from being scratched and damaged when the first pressing switch 331 or the second pressing switch 332 is pressed.

Under the condition that the magnetic valve core 325 is in the first connection position and the water through hole 3251 connects the first water inlet pipe 322 and the water outlet pipe 324, the left end of the magnetic valve core 325 is clamped in the limit step 3212 at the left end of the water through cavity 3211 and abuts against the left side of the hole section with smaller radial dimension, so that the left sliding is continued limited by the limit step 3212, the magnetic valve core 325 is prevented from excessively extruding a spring at the left side, and meanwhile, the situation that the water through hole 3251 cannot reliably align the first water inlet pipe 322 and the water outlet pipe 324 due to the fact that the magnetic valve core 325 moves over is also avoided. Based on the similar situation, under the condition that the magnetic valve core 325 is in the second on position and the water through hole 3251 connects the second water inlet pipe 323 and the water outlet pipe 324, the right end of the magnetic valve core 325 is clamped in the limit step 3212 at the right end of the water through cavity 3211.

The water using member 22 includes at least one wash tank provided at the bottom of the receiving compartment 111 and a contaminated water collecting tank 23 communicated with the wash tank, and as an example, in case that the number of the floor wiping members is two, the number of the wash tanks is two, each of which can receive one floor wiping member. The two cleaning tanks are respectively communicated to the sewage water collecting tank 23 through the water guide tank, the combined cleaning equipment further comprises a sewage discharge pipe 24 communicated with the sewage water collecting tank 23, a sewage discharge pump 25 is arranged on the sewage discharge pipe 24, and the water outlet end of the sewage discharge pipe is communicated with the outside, so that sewage of the cleaning and floor scrubbing component in the cleaning tanks can be discharged.

Of course, the overall pipeline layout scheme of the washing device 1 and the sweeping robot 2 of the combined cleaning device is not limited to the above example, for example, the drain pipe 24 may also be combined with the downstream drain pipe of the washing device 1 (i.e., the pipe section part of the washing device 1 communicated to the floor drain), or the water inlet branch pipe 13 may be independently arranged with the water inlet pipeline of the washing device 1 so as to independently control the water inlet of the washing device 1 and the sweeping robot 2, so that the three-way valves on the water inlet pipelines of the washing device 1 and the sweeping robot 2 do not depend on the power supply of the washing device 1, the control is simpler and more convenient, and the pipeline layout scheme provided may meet the water inlet and outlet requirements of the washing device 1 and the sweeping robot 2.

In the second preferred embodiment of the present invention, different from the first preferred embodiment, the magnetic permeable valve core 325 is provided with or is a magnetic structure, the electromagnetic device includes only one electromagnetic structure, the electromagnetic structure is provided near the left end or the right end of the water passing cavity 3211, the pressing structure includes a first pressing switch 331 capable of making the electromagnetic structure in a first energized state and a second pressing switch 332 capable of making the electromagnetic structure in a second energized state, wherein the current directions of the first energized state and the second energized state are opposite, so that the magnetic poles on the side of the electromagnetic structure near the magnetic permeable valve core 325 are opposite in the two energized states. The first pressing state is a state in which the first pressing switch 331 is pressed, the first power-on state is a state in which the magnetic attraction (or repulsion) of the electromagnetic structure is enabled to bring the magnetic valve core 325 close to the first water inlet nozzle 322 to slide, the second pressing state is a state in which the second pressing switch 332 is pressed, and the second power-on state is a state in which the magnetic repulsion (or attraction) of the electromagnetic device is enabled to bring the magnetic structure and the magnetic valve core 325 close to the second water inlet nozzle 323 to slide. Based on the structure, the sweeping robot 2 can selectively trigger any one of two water inlet situations of the water using component 22 through two push switches, and the magnetic valve core 325 can be driven to move along the left and right directions through only one electromagnetic structure.

Based on the combined cleaning device of any one of the above embodiments, the present invention also provides a control method of a combined cleaning device, the control method including:

the sweeping robot 2 triggers the first pressing condition or the second pressing condition of the pressing structure according to the water inlet requirement so that the valve element 32 is communicated with the first water inlet pipe orifice 322 or the second water inlet pipe orifice 323;

the floor sweeping robot 2 moves the floor wiping component into the water component 22;

when water exists in the water member 22 or the water level reaches a set water level, the sweeping robot 2 rotates the floor wiping member and starts the sewage pump 25, so that the floor wiping member is cleaned;

acquiring the turbidity of the water discharged by the water member 22 in the process of cleaning the floor wiping member;

if the obtained turbidity is not higher than the set turbidity, the electromagnetic device is powered off, and the cleaning robot 2 is enabled to finish cleaning;

the dredge pump 25 is turned off after the draining is finished.

In the above step, the turbidity of the washing water may be acquired by a turbidity sensor provided in the water using member 22 or the soil discharging pipe 24. Based on the above steps, the sweeping robot 2 can automatically return to the receiving compartment 111 and selectively trigger a connection state of the valve 32 when the floor cleaning member needs to be cleaned, so as to use the tap water or the rinsing water in the water member 22 and rotate the floor cleaning member to perform agitation cleaning when the water inflow in the water member 22 is sufficient. In the process, the cleaning progress of the scrubbing component is determined by monitoring the turbidity of the water discharged by the water component 22, and when the turbidity of the water discharged by the water component 22 is not higher than the set turbidity and the dirt and dust on the scrubbing component can not be separated basically, the cleaning work of the scrubbing component is determined to be completed basically, at the moment, the control electromagnetic device is powered off, so that the valve 32 is closed, no water is fed into the water component 22, the sweeping robot 2 is controlled to exit from the accommodating cabin 111, and the cleaning work of the scrubbing component is finished completely. The water inlet demand can be determined by the current water storage amount in the water storage member 21 or a water inlet requirement set by a user, for example, when the water storage amount in the water storage member 21 is not lower than a set water level, the sweeping robot 2 is controlled to always trigger the first pressing condition, and the rinsing water stored in the water storage member 21 is introduced into the water member 22.

As shown in fig. 6A-6C, fig. 6A shows a route when the floor sweeping robot 2 does not need to clean the floor components, and directly moves to the front of the opening of the accommodating compartment 111 and moves into the accommodating compartment 111 for charging, fig. 6B shows a route when the floor sweeping robot 2 needs to clean the floor components, and moves to the floor cleaning components above the water member 22 after triggering the first push switch 331 and charges, fig. 6C shows a route when the floor sweeping robot 2 needs to clean the floor components, and moves to the floor cleaning components above the water member 22 after triggering the second push switch 332 and charges. As an example, the bottom of the housing 11 of the laundry device 1 is provided with a receiving compartment 111, the water member 22 is disposed at the bottom of the receiving compartment 111, the pressing structure comprises a first pressing switch 331 and a second pressing switch 332 which can be respectively disposed at the left and right side walls of the receiving compartment 111, a first pressing condition which can trigger the valve member 32 to switch on the first water inlet pipe opening 322 is that the first pressing switch 331 is pressed, a second pressing condition which can trigger the valve member 32 to switch on the second water inlet pipe opening 323 is that the second pressing switch 332 is pressed, a positioning device which can enable the sweeping robot 2 to face the opening of the receiving compartment 111 is disposed at the middle position of the receiving compartment 111,

the step of "making the robot 2 of sweeping the floor trigger the first state of pressing or the second state of pressing the structure according to the demand of intaking" includes specifically:

the sweeping robot 2 is moved to a position opposite to the opening of the accommodating cabin 111 through the positioning device;

acquiring an actual distance between the current position of the sweeping robot 2 and the first press switch 331 or the second press switch 332 in the longitudinal direction;

enabling the sweeping robot 2 to move leftwards or rightwards by a first set distance according to a triggering requirement and move the actual distance along the longitudinal direction to trigger a first pressing situation or a second pressing situation;

the step of moving the floor sweeping member into the water member 22 by the floor sweeping robot 2 specifically comprises the following steps:

the sweeping robot 2 is moved above the water usage member 22, wherein,

the first set distance is the distance in the lateral direction between the intermediate position of the housing compartment 111 and the position where it is able to trigger the first pressing situation or the second pressing situation of the sweeping robot 2.

In the above steps, the manner of moving the sweeping robot 2 to the position facing the opening of the accommodating compartment 111 through the positioning device may be any known positioning manner, for example, an environment map positioning method, a beacon positioning method, a laser positioning method, an infrared positioning method, or the like can be used to control the sweeping robot 2 to move to the front of the opening of the accommodating compartment 111 in combination with the positioning coordinate point of the positioning device, so that the sweeping robot 2 faces the position of the positioning device. If the sweeping robot 2 is located in the front area opposite to the opening of the accommodating cabin 111, the sweeping robot 2 is controlled to directly and transversely move to the position opposite to the opening of the accommodating cabin 111. If the sweeping robot 2 is located behind or beside the accommodating compartment 111, the sweeping robot 2 may be controlled to move to the front area of the accommodating compartment 111, and then the sweeping robot 2 is controlled to move to a position facing the opening of the accommodating compartment 111 along the transverse direction.

The "actual distance in the longitudinal direction between the current position of the sweeping robot 2 and the first push switch 331 or the second push switch 332" is a projected distance in the longitudinal direction between the current position of the sweeping robot 2 and the position of the first push switch 331 or the second push switch 332, which is calculated from the positioning coordinate points of the positioning device, for example, when the positioning means is provided at the rear-side midpoint position of the accommodation compartment 111 (if the calculation simplicity is not taken into consideration, the positioning means may be provided at virtually any position in the accommodation compartment 111), and the projected distance in the longitudinal direction between the positioning means and the first push switch 331 or the second push switch 332 is a meters, if the projection distance between the sweeping robot 2 and the positioning device in the longitudinal direction is B meters, the projection distance between the sweeping robot 2 and the push switch to be triggered in the longitudinal direction is (B-A) meters.

Considering that the distance between the middle of the accommodating compartment 111 and the first push switch 331 or the second push switch 332 is fixed, assuming that the distance is C meters, if the radius of the sweeping robot 2 is R meters, and the pressing depth is L meters, the first set distance is (C-R-L) meters.

Under the condition that the press switch which needs to be triggered by the sweeping robot 2 is determined, the sweeping robot 2 is controlled to move leftwards or rightwards for a first set distance according to the water inlet requirement, then the sweeping robot 2 is controlled to move along the longitudinal direction (B-A) meter, the sweeping robot 2 can be moved to the triggering position to press the corresponding press switch, and the corresponding pressing condition is triggered (the execution sequence of the steps of transverse movement and longitudinal movement can be exchanged).

Further, the positioning device is a positioning module of the charging device 34 of the sweeping robot 2, the charging device 34 is disposed at a middle position of a rear side wall of the accommodating compartment 111, and when the sweeping robot 2 contacts the charging device 34 for charging, the sweeping robot 2 is located above the water member 22 (i.e. the water member 22 is located on a central axis of the bottom of the accommodating compartment 111), and the step of "moving the sweeping robot 2 to above the water member 22" specifically includes:

the sweeping robot 2 moves a second set distance to the middle part along the transverse direction;

the sweeping robot 2 is moved in the longitudinal direction and the charging device 34 is switched on.

In the above steps, since the lateral distance (i.e. the second set distance) and the longitudinal distance between the position for triggering the first push switch 331 or the position for triggering the second push switch 332 relative to the position of the water using member 22 are fixed, such as X meters and Y meters, after the sweeping robot 2 presses the first push switch 331 or the second push switch 332, the sweeping robot 2 moves X meters in the lateral direction and Y meters in the longitudinal direction to the middle position in the accommodating compartment 111, that is, the sweeping robot 2 moves to the position directly above the water using member 22 and the charging device 34 starts to charge. The charging device 34 may be any device that can be contacted or connected to the charging device 34 by the sweeping robot 2 to charge the sweeping robot 2, such as an induction charging socket or a plug-in charging socket.

Through the arrangement, the sweeping robot 2 can be charged above the water using component 22 through the charging device 34, so that the sweeping robot 2 can supplement the consumed electric energy while washing the floor wiping component, the original electric energy of the sweeping robot 2 before the floor wiping component is cleaned cannot be consumed due to the cleaning work of the floor wiping component, and the cruising ability is strong.
