The suction source 420 is connected to the recovery path to provide a negative pressure to the recovery path; in a particular embodiment, the suction source 420 may be connected to the recovery tank 410 to indirectly apply negative pressure to the recovery path through the recovery tank 410 and further to the suction inlet.

The cleaning base 600 according to an embodiment of the present disclosure may further include: the connector module 640 is installed and by connecting the connector module 640 to the connection portion 500, the cleaning base 600 can be connected to the main body portion 200 such that at least a portion of the cleaning module 610 of the cleaning base 600 can be brought into contact with a surface to be cleaned when the wet surface cleaning apparatus is operated, thereby enabling cleaning of the surface to be cleaned.

The cleaning base 600 further includes a housing module 650, the mounting adapter module 640 being rotatably disposed within the housing module 650, the housing module 650 being formed to clean at least a portion of an outer surface of the base 600 and being capable of providing support for the cleaning module 610 and the fluid distribution module 620 as described above.

Wherein the cleaning module 610 may be disposed at the front of the housing module 650 and received in the brush chamber formed by the housing module 650.

The cleaning base 600 may further include a moving wheel module 660, the moving wheel module 660 being coupled to the housing module 650, the moving wheel module 660 being in contact with and rolling over the surface to be cleaned when the wet surface cleaning apparatus is in operation to reduce the power required to move the wet surface cleaning apparatus and also to effectively prevent the cleaning base 600 from contaminating the surface that has been cleaned.

The moving wheel module 660 is disposed at the housing module 650 such that the lowest point of the moving wheel module 660 is located below the lowest point of the housing module 650, such that when the wet surface cleaning apparatus is in operation, the moving wheel module 660 contacts and rolls on the surface to be cleaned, thereby reducing the power required for movement of the wet surface cleaning apparatus; the moving wheel module 660 is located at the rear side of the housing module 650 to be able to effectively prevent the cleaning base 600 from contaminating the surface after cleaning has been performed.

The moving wheel module 660 includes a moving wheel frame 661 and a moving wheel 662. Wherein the moving wheel housing 661 is formed separately from the case module 650, and the case module 650 is connected to the moving wheel housing 661 such that the case module 650 can move with respect to the moving wheel housing 661. For example, the housing module 650 has at least one degree of freedom of rotation with respect to the moving truck 661, and preferably, the housing module 650 has two degrees of freedom of rotation with respect to the moving truck 661, i.e., a pitch degree of freedom (Y-axis) and a roll degree of freedom (X-axis).

The housing module 650 is formed with a connection neck 652, and in the present disclosure, an axis of the connection neck 652 is disposed in a front-rear direction, and a rotation ring 663 is disposed outside the connection neck 652, and the connection neck 652 is allowed to rotate within the rotation ring 663, so that the housing module 650 has a tumbling degree of freedom. Also, the rotating ring 663 is rotatably provided to the connecting portion 6612, wherein the axis of rotation of the rotating ring 663 with respect to the connecting portion 6612 is parallel to the axis of rotation of the moving wheel 662 and is not collinear, so that the housing module 650 has a degree of freedom in pitch. The connecting portion 6612 is used to connect two mounting portions 6611, and each mounting portion 6611 may have a moving wheel 662 mounted thereon.

When the cleaning base 600 is used, since the area to be cleaned by the flexible annular band portion is large, if the unevenness of the ground at home is encountered, one surface is determined by three points, which inevitably results in the moving wheel 662 or the flexible annular band portion not being able to contact the ground at the same time, if only one end of the flexible annular band portion is contacted with the ground, the other end inevitably is not able to well contact the ground, resulting in an unsatisfactory cleaning effect.

The wet surface cleaning apparatus of the present disclosure may further comprise a controller for controlling the operation of the suction source 420, the drive 611 of the cleaning module 610 and/or the fluid pump 621.

Specifically, the controller is configured to perform a post-cleaning operation in which the controller controls the fluid pump 621 to apply a negative pressure to the fluid dispenser 622, and the controller controls the suction source 420 to remain activated.

Thus, after the user completes the cleaning operation of the surface to be cleaned, a signal for stopping the cleaning operation is input through the control section 111; upon receiving the signal to stop the cleaning operation, the controller performs a post-cleaning operation in which the controller controls the fluid pump 621 to apply a negative pressure to the fluid dispenser 622, and draws back the cleaning liquid in the fluid dispenser 622 and the cleaning liquid in the dispensing path into the cleaning liquid storage 300, thereby making it possible to prevent the dispensing path and the fluid dispenser 622 from dripping onto the floor.

Also, in the post-cleaning operation, the controller controls the suction source 420 to remain activated, and thus, even if there is some of the fluid dispenser 622 and the cleaning liquid in the dispensing path to drip on the surface to be cleaned, it can be sucked into the recovery storage part 400 through the suction port, thereby further ensuring that there is no cleaning liquid on the surface to be cleaned.

In another aspect, the controller may be configured to perform at least one of a cleaning operation and a post-cleaning operation. For example, when a user cleans a surface to be cleaned using a wet surface cleaning apparatus, the controller may be configured to perform a cleaning operation by inputting a signal to start a cleaning job through the control section 111 or APP; accordingly, when the cleaning job is ended, the user inputs a signal to end the cleaning job through the control part 111 or APP, and the controller may be configured to perform the post-cleaning operation.

Specifically, the controller is configured to control the fluid pump 621 to flow the cleaning liquid in a first direction during the cleaning operation is performed, whereby the cleaning liquid is delivered to the fluid dispenser 622; and controls the fluid pump 621 so that the cleaning liquid flows in a second direction opposite to the first direction during the post-cleaning operation, whereby the cleaning liquid is delivered from the fluid dispenser 622 to the cleaning liquid storage 300.

Preferably, the fluid pump 621 may be a peristaltic pump, which has the advantages of high precision, good self-priming capability, idling, reversible fluid, and the like, so that when the fluid pump 621 rotates in a first direction, the cleaning liquid flows in the first direction; accordingly, the fluid pump 621 rotates in the second direction, so that the cleaning liquid flows in the second direction. Specifically, the fluid pump 621 rotates in a forward direction to allow the cleaning liquid to flow in a first direction, and the fluid pump 621 rotates in a reverse direction to allow the cleaning liquid to flow in a second direction.

In one embodiment, the fluid pump 621 is for pressurizing cleaning liquid within the dispensing path, and the controller is configured to: performing a cleaning operation: and after the controller receives an instruction for cleaning the surface to be cleaned triggered by a user, executing the cleaning operation. In performing a cleaning operation, the suction source 420, the fluid pump 621 and the drive 611 of the cleaning module are activated, wherein the fluid pump 621 operates in a first direction for a first time at a first flow rate.

Specifically, the first flow rate may be 200ml/min, thereby enabling the cleaning liquid to quickly fill the distribution path by supplying a large amount of the cleaning liquid, and the cleaning module 610 is supplied with the cleaning liquid such that the cleaning module 610 is more quickly in a wet state, thereby enabling wet cleaning of the floor.

Accordingly, the first time may be 5-6 seconds, that is, the cleaning module 610 is in a wet state by supplying about 20ml of the cleaning liquid.

The controller may be further configured to: performing post-cleaning operations: when the cleaning of the surface to be cleaned is finished, or the cleaning of the surface to be cleaned needs to be suspended or stopped due to other situations, the user triggers the control part 111 or sends an instruction to stop cleaning the surface to be cleaned to the controller through the APP, and after the controller receives the instruction to stop cleaning the surface to be cleaned triggered by the user, the post-cleaning operation is performed. The fluid pump 621 is activated when a post-cleaning operation is performed, wherein the fluid pump 621 operates in a second direction at a second flow rate for a second time.

In the present disclosure, when the post-cleaning operation is performed, the fluid pump 621 is immediately controlled to operate in the second direction at the second flow rate for the second time upon receiving an instruction to pause or stop cleaning the surface to be cleaned.

Specifically, in the present disclosure, the second flow rate is equal to or greater than the first flow rate, for example, the second flow rate may be 200ml/min, so that the cleaning liquid in the fluid dispenser 622 can be quickly pumped back to the cleaning liquid storage 300, and the cleaning liquid in the dispensing path can also be pumped back to the cleaning liquid storage 300.

Accordingly, the second time may be 5-15 seconds, thereby enabling the cleaning liquid within the fluid dispenser 622 to be completely pumped back to the cleaning liquid storage 300.

In the present disclosure, when the cleaning operation is performed, if the cleaning module 610 is in the wet state, the flow rate of the cleaning liquid supplied to the cleaning module 610 may be reduced. In particular, the controller is configured to activate the fluid pump 621 to provide cleaning liquid in a first flow direction and at a third flow rate when performing a cleaning operation, wherein the third flow rate is less than the first flow rate, thereby enabling a more economical usage of cleaning liquid, resulting in a wet surface cleaning device with a larger cleaning area in a single use. Preferably, the third flow rate may be 40-100 ml/min.

In one implementation, the wet surface cleaning apparatus further comprises a user interaction assembly through which a user can interact with the wet surface cleaning apparatus, wherein the controller is operatively coupled with the user interaction assembly to receive input from the user, and the controller is configured to perform a post-cleaning operation when a user selects to end a cleaning operation. As a preferred implementation form, the user interaction component may be a touch screen.

The wet surface cleaning apparatus may further comprise a rechargeable battery 800, the rechargeable battery 800 being at least used for powering the suction source 420, the suction source 420 and the driving means 611 of the cleaning module. Accordingly, the wet surface cleaning apparatus may further comprise a battery charging circuit 700, the battery charging circuit 700 being for controlling charging of the rechargeable battery 800; wherein the performing a post-cleaning operation includes a charge-hold phase including maintaining at least one time the battery charging circuit 700 is active during self-cleaning. That is, the rechargeable battery 800 can be charged during self-cleaning as well.

In a preferred embodiment, the post-cleaning operation includes intermittently applying power to the drive 611 to incrementally rotate the cleaning module and also to enable cleaning of water stains on the surface to be cleaned by rotation of the cleaning module 610.

In the present disclosure, the wet surface cleaning apparatus is dockable with a base station, wherein the base station comprises a heater and an evacuation motor capable of generating a forced airflow over the base station;

the controller is configured to activate the heater and the vacuum motor to heat the forced airflow by the heater and cause the heated forced airflow to pass only through the cleaning module during the post-cleaning operation, thereby enabling drying of the cleaning module by the forced airflow.

Providing a first power to the suction source 420 while performing the cleaning operation; the second power is provided to the suction source 420 during the post-cleaning operation, wherein the first power is greater than the second power, thereby enabling power savings during the post-cleaning operation.

According to another aspect of the present disclosure, as shown in fig. 8, there is provided a method of operating a wet surface cleaning apparatus, wherein the wet surface cleaning apparatus is the wet surface cleaning apparatus described above, the method comprising:

wherein performing post-cleaning operations comprises: to power a fluid pump 621 in communication with a fluid dispenser 622; and a fluid pump 621 applies negative pressure to the fluid dispenser 622.

More preferably, the suction source 420 may be controlled to remain activated when the fluid pump 621 applies a negative pressure to the fluid dispenser 622.

Also, in the post-cleaning operation, the controller controls the suction source 420 to remain activated, and thus, even if there is a portion of the fluid dispenser 622 and the cleaning liquid in the dispensing path drips on the surface to be cleaned, it can be sucked into the recovery storage part 400 through the suction port, thereby further ensuring that there is no cleaning liquid on the surface to be cleaned.

Preferably, the fluid pump 621 may be selected to be a peristaltic pump, such that when the fluid pump 621 rotates in a first direction, the cleaning liquid flows in the first direction; accordingly, the fluid pump 621 rotates in the second direction, so that the cleaning liquid flows in the second direction. Specifically, the fluid pump 621 rotates in a forward direction to allow the cleaning liquid to flow in a first direction, and the fluid pump 621 rotates in a reverse direction to allow the cleaning liquid to flow in a second direction.

In one embodiment, the fluid pump 621 is for pressurizing cleaning liquid within the dispensing path, and the controller is configured to: performing a cleaning operation: and after the controller receives an instruction for cleaning the surface to be cleaned triggered by a user, performing a cleaning operation. In performing a cleaning operation, the suction source 420, the fluid pump 621 and the drive 611 of the cleaning module are activated, wherein the fluid pump 621 operates in a first direction for a first time at a first flow rate.

In particular, the first flow rate may be 200ml/min, thereby enabling wet cleaning of the floor by providing a large amount of cleaning liquid such that the cleaning module 610 is more quickly in a wet state.

The controller may be further configured to: performing a post-cleaning operation: when the cleaning of the surface to be cleaned is finished, or when the cleaning of the surface to be cleaned needs to be suspended or stopped due to other situations, the user triggers the control part 111 or sends an instruction to stop cleaning of the surface to be cleaned to the controller through the APP, and after the controller receives the instruction to stop cleaning of the surface to be cleaned triggered by the user, the post-cleaning operation is performed. The fluid pump 621 is activated when a post-cleaning operation is performed, wherein the fluid pump 621 operates in a second direction at a second flow rate for a second time.

Specifically, the second flow rate may be 200ml/min, thereby enabling the cleaning liquid within the fluid dispenser 622 to be drawn back to the cleaning liquid reservoir 300 as quickly as possible.

In the present disclosure, when the cleaning operation is performed, if the cleaning module 610 is in the wet state, the flow rate of the cleaning liquid supplied to the cleaning module 610 may be reduced. In particular, the controller is configured to activate the fluid pump 621 to provide cleaning liquid in a first flow direction and at a third flow rate when performing a cleaning operation, wherein the third flow rate is less than the first flow rate, thereby enabling a more economical usage of cleaning liquid, resulting in a wet surface cleaning device with a larger cleaning area in a single use.
