[0006] Existing cleaning systems (such as sweepers, floor scrubbers, etc.) are usually composed of two parts: a cleaning host and a base station. The cleaning host and the base station use a dual-fan structure for waste treatment.

[0007] More specifically, the cleaning host is equipped with a recycling box and a first negative pressure device, and the base station is equipped with a second negative pressure device. When the cleaning host is performing cleaning work or self-cleaning, the first negative pressure device is activated to generate negative pressure in the recycling box, thereby sucking dirt generated by cleaning components (such as roller brushes, mopping turntables, etc.) into the recycling box. When the cleaning host is docked with the base station, the second negative pressure device is activated to generate negative pressure in the base station, thereby sucking dirt in the recycling box into the base station, thereby achieving automatic cleaning of dirt in the cleaning host. However, the above-mentioned dual-fan structure is relatively complex and not conducive to installation and maintenance.

DETAILED DESCRIPTION

[0077] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0078] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0079] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0080] Referring to Figures 1 and 2 , the present application provides a cleaning system, which can be a sweeper, a scrubber, a vacuum cleaner, etc. The cleaning system includes a cleaning host 100, a base station 200, and a circulation mechanism 300. The cleaning host 100 includes a negative pressure device 110, which is specifically an airflow generating structure such as a fan. The circulation mechanism 300 has a first working state that connects the negative pressure device 110 and the base station 200. When the base station 200 is docked with the cleaning host 100, the circulation mechanism 300 switches to the first working state, allowing the negative pressure device 110 to act on the base station 200 to suck dirt from the cleaning host 100 into the base station 200.

[0081] With the above structure, when the cleaning host 100 needs to discharge sewage, the cleaning host 100 can be docked to the base station 200, and at the same time the circulation mechanism 300 is switched to the first working state to connect the base station 200 and the negative pressure device 110. The negative pressure device 110 can drive the base station 200 to generate negative pressure so that the dirt on the cleaning host 100 is drawn into the base station 200, thereby realizing self-cleaning of the cleaning host 100; there is no need to set an additional negative pressure device 110 on the base station 200, the structure is simple, the base station 200 is easy to assemble and maintain, and the production cost is effectively reduced.

[0082] Furthermore, in one embodiment, the dirt on the cleaning host 100 may specifically be dirt attached to cleaning components (such as a roller brush, a mopping turntable, etc.), and the base station 200 is used to clean and suck the dirt on the cleaning components.

[0083] A sewage discharge pipeline can be provided inside the base station 200, and the negative pressure device 110 acts on the sewage discharge pipeline to receive waste from the cleaning host 100 through the sewage discharge pipeline and discharge it away from the base station 200. Alternatively, a sewage collection chamber can be provided inside the base station 200 to collect waste in the sewage collection chamber. The sewage collection chamber can be connected to the sewage discharge pipeline.

[0084] Specifically, in one embodiment, as shown in FIG12 , a dirt collection container 210 is detachably provided on the base station 200. A dirt collection cavity is formed on the dirt collection container 210, and the dirt collection container 210 is connected to a sewage discharge pipeline, so that the base station 200 can temporarily store dirt, thereby improving the installation adaptability of the base station 200. When the dirt collection cavity needs to be cleaned, the dirt collection container 210 only needs to be removed from the base station 200. In addition, a clean water container 220 is also detachably provided on the base station 200. The clean water container 220 is used to temporarily store cleaning liquid, which is then drawn out through the clean water pipeline within the base station 200 to replenish or clean the cleaning host 100.

[0085] Of course, in another embodiment, as shown in Figure 13 , the waste collection container 210 may not be provided on the base station 200. Instead, the waste drainage pipeline may extend beyond the base station 200 and connect to an external waste drainage pipeline. Waste drawn into the base station 200 can be automatically discharged to the external waste drainage pipeline, thereby eliminating manual dumping and improving the user experience. Alternatively, the clean water container 220 may not be provided on the base station 200. The clean water pipeline within the base station 200 may be directly connected to an external water source, enabling automatic refilling.

[0086] Preferably, in this embodiment, the cleaning host 100 also includes a recycling box 120, and the circulation mechanism 300 also has a second working state for connecting the negative pressure device 110 and the recycling box 120. When the cleaning host 100 needs to perform a sewage suction task, such as performing a cleaning task (such as cleaning dirt on the floor, walls, etc.), a self-cleaning task, etc., the circulation mechanism 300 switches to the second working state, so that the negative pressure device 110 can act on the recycling box 120 to suck external dirt into the recycling box 120, and when the cleaning host 100 is docked with the base station 200, the recycling box 120 can be connected to the base station 200. At this time, the circulation mechanism 300 switches to the first working state to draw the dirt in the recycling box 120 into the base station 200.

[0087] With the above structure, when the cleaning components are dirty, the recycling box 120 can suck external dirt in real time. The base station 200 does not need to frequently dock with the cleaning host 100 to suck the dirt on the cleaning components. It is only necessary to wait until the recycling box 120 is full of dirt before docking the cleaning host 100 to the base station 200, and the dirt in the recycling box 120 is centrally extracted through the base station 200, which significantly improves the cleaning efficiency of the cleaning host 100.

[0088] Furthermore, in one embodiment, the circulation mechanism 300 can switch between states manually. For example, a handle is provided on the circulation mechanism 300, and a user can operate the handle to make the circulation mechanism 300 present the first working state or the second working state.

[0089] Preferably, as shown in Figures 1 to 3, in this embodiment, the cleaning system further includes a state adjustment unit 400 connected to the circulation mechanism 300 by signal. The state adjustment unit 400 is adapted to detect and switch the position state of the circulation mechanism 300. When the base station 200 is docked with the cleaning host 100, the state adjustment unit 400 can control the circulation mechanism 300 to be in the first working state according to the position state.

[0090] With the above structure, the state adjustment unit 400 can automatically switch the position state of the circulation mechanism 300, thereby improving the degree of intelligence and ease of operation, and the state adjustment unit 400 can also detect the position state of the circulation mechanism 300 in real time. When the cleaning host 100 and the base station 200 are docked, the state adjustment unit 400 can control the circulation mechanism 300 to switch to the first working state according to the position state, thereby improving the reliability and accuracy of the state switching.

[0091] In addition, when a recovery box 120 is provided on the cleaning host 100, the circulation mechanism 300 also has a second working state. When the cleaning host 100 performs the sewage suction task, the state adjustment unit 400 can also control the circulation mechanism 300 to be in the second working state according to the position state to connect the negative pressure device 110 and the recovery box 120, so that the negative pressure device 110 can reliably act on the recovery box 120.

[0092] Furthermore, in one embodiment, the state adjustment unit 400 may obtain the position state of the circulation mechanism 300 in real time through an encoder to control the circulation mechanism 300 to switch between the first working state and the second working state.

[0093] In this embodiment, the state adjustment unit 400 includes a position sensor 410 and a controller 420. The position sensor 410 is used to detect the position state of the circulation mechanism 300. The controller 420 is signal-connected to the position sensor 410 and the circulation mechanism 300 respectively. The controller 420 is suitable for controlling the circulation mechanism 300 to switch between the first working state and the second working state according to the position state detected by the position sensor 410, thereby reducing costs and improving detection accuracy and reliability.

[0094] Specifically, as shown in Figures 4 and 5 , the position sensor 410 can be a Hall switch. The circulation mechanism 300 includes a trigger member 310. The position sensor 410 detects the position of the trigger member 310 to obtain the position state of the circulation mechanism 300. The controller 420 is adapted to control the circulation mechanism 300 to switch between the first operating state and the second operating state based on the trigger state between the trigger member 310 and the position sensor 410.

[0095] In one embodiment, the position sensor 410 includes a first position sensor 412 and a second position sensor 413. When the trigger member 310 triggers the first position sensor 412, the circulation mechanism 300 is in the first operating state. When the trigger member 310 triggers the second position sensor 413, the circulation mechanism 300 is in the second operating state. This structure facilitates the controller 420 to receive detection signals from different position sensors 410, thereby quickly determining the position state of the circulation mechanism 300.

[0096] Of course, in another embodiment, the trigger member 310 includes a first trigger member and a second trigger member. When the first trigger member triggers the position sensor 410, the circulation mechanism 300 is in the first operating state. When the second trigger member triggers the position sensor 410, the circulation mechanism 300 is in the second operating state. This structure can reduce the number of position sensors 410, simplify the structure, and reduce costs.

[0097] Furthermore, the circulation mechanism 300 is set on the cleaning host 100 or the base station 200, or is set independently of the cleaning host 100 and the base station 200, that is, it is sufficient to ensure that the circulation mechanism 300 can achieve conductivity between the recycling box 120 and the negative pressure device 110 and conductivity between the base station 200 and the negative pressure device 110.

[0098] Since the negative pressure device 110 is located on the cleaning host 100, when the cleaning host 100 performs cleaning operations, it will separate from the base station 200 and move freely. In this embodiment, the circulation mechanism 300 is preferably set on the cleaning host 100. Compared with being set on the base station 200 or being set independently, the circulation mechanism 300 in this embodiment can move synchronously with the cleaning host 100 to avoid restricting the movement of the cleaning host 100, so as to reliably maintain the connection between the negative pressure device 110 and the recovery box 120, and the circulation mechanism 300 is closer to the negative pressure device 110, thereby reducing power loss, improving the suction force of the cleaning operation of the cleaning host 100 and / or the sewage discharge operation of the base station 200, and improving the cleaning effect and sewage discharge effect.

[0099] Furthermore, as a preferred embodiment, in the first working state, the circulation mechanism 300 blocks the flow path between the negative pressure device 110 and the recovery box 120; in the second working state, the circulation mechanism 300 blocks the flow path between the negative pressure device 110 and the base station 200.

[0100] By adopting the above-mentioned method, the circulation mechanism 300 only has a first working state and a second working state, thereby avoiding the situation where the circulation mechanism 300 has two working states at the same time. When the cleaning host 100 performs the sewage suction task, the negative pressure device 110 and the base station 200 can be prevented from being connected, so that the suction force of the negative pressure device 110 is concentrated on the cleaning host 100, ensuring the suction effect of the recovery box 120 on external sewage, and avoiding the situation where the sewage is driven to remain in the sewage pipeline of the base station 200 due to the partial suction force of the base station 200, thereby ensuring the cleanliness of the sewage pipeline; when the cleaning host 100 is docked with the base station 200, the negative pressure device 110 and the cleaning host 100 can be prevented from being connected, so that the suction force of the negative pressure device 110 is concentrated on the base station 200, ensuring the suction effect of the base station 200 on sewage, and also avoiding the external sewage being continuously sucked into the recovery box 120 and affecting the normal sewage discharge effect.

[0101] Specifically, the circulation mechanism 300 includes an air cavity structure 320, a switching structure, and a driving member 330. The air cavity structure 320 is used to communicate with the recovery box 120, the negative pressure device 110, and the base station 200. The switching structure is movably installed in the air cavity structure 320. The driving member 330 is transmission-connected to the switching structure and is signal-connected to the controller 420. The driving member 330 is adapted to drive the switching structure to move under the control of the controller 420 to drive the air cavity structure 320 to a first working state or a second working state. When the air cavity structure 320 is in the first working state, the air cavity structure 320 can communicate with the negative pressure device 110 and the base station 200, while the switching structure blocks the recovery box 120 and the negative pressure device 110. When the air cavity structure 320 is in the second working state, the air cavity structure 320 can communicate with the negative pressure device 110 and the recovery box 120, while the switching structure blocks the base station 200 and the negative pressure device 110.

[0102] Furthermore, the air cavity structure 320 is a hollow shell having a closed inner cavity. The air cavity structure 320 is provided with a first connection port 321, a second connection port 322 and a third connection port 323 connected to the inner cavity. The first connection port 321 can be connected to the negative pressure device 110, the second connection port 322 can be connected to the base station 200, and the third connection port 323 can be connected to the recycling box 120.

[0103] When in the first working state, the first connection port 321 and the second connection port 322 are connected to form a first air duct 324. At the same time, the switching structure blocks the third connection port 323. The negative pressure device 110 and the base station 200 are connected through the first air duct 324, so that the base station 200 generates negative pressure, thereby enabling the base station 200 to clean the recycling box 120, and avoiding the recycling box 120 and the negative pressure device 110 being in a conductive state, causing air flow diversion and affecting the sewage discharge effect. When in the second working state, the first connection port 321 and the third connection port 323 are connected to form a second air duct 325. At the same time, the switching structure blocks the second connection port 322. The negative pressure device 110 and the recycling box 120 are connected through the second air duct 325, so that the recycling box 120 generates negative pressure, thereby enabling the recycling box 120 to suck external dirt, and avoiding the base station 200 and the negative pressure device 110 being in a conductive state when the cleaning system does not need to discharge dirt, causing air flow diversion and affecting the suction effect of the recycling box 120.

[0104] Furthermore, the switching structure can use rotational motion and / or translational motion to switch the air ducts. In this embodiment, the switching structure is preferably rotationally connected to the air cavity structure 320. In response to the rotational operation, the switching structure drives the air cavity structure 320 to present the first air duct 324 or the second air duct 325, thereby facilitating the operation of the switching structure and simplifying the connection structure between the switching structure and the air cavity structure 320. Accordingly, the driving member 330 can be a rotary motor, directly or indirectly connected to the switching structure and driving its rotation; or the driving member 330 can be a linear motor, with a transmission structure connected between the driving member 330 and the switching structure to convert linear motion into rotational motion to achieve rotation of the switching structure.

[0105] Preferably, the driving member 330 is arranged outside the wind cavity structure 320, and the switching structure part extends from the inside of the wind cavity structure 320 to the outside of the wind cavity structure 320 to be connected to the driving member 330 for transmission, thereby facilitating the installation of the driving member 330 and reducing the obstruction of the air flow inside the wind cavity structure 320.

[0106] The position sensor 410 can be arranged inside the wind cavity structure 320 or outside the wind cavity structure 320. The position sensor 410 is fixedly connected to one of the wind cavity structure 320 or the switching structure. The trigger member 310 is fixedly connected to the other of the wind cavity structure 320 or the switching structure. When the switching structure blocks the second connection port 322 or the third connection port 323, the trigger member 310 can trigger the position sensor 410.

[0107] As a preferred embodiment, the position sensor 410 is located outside the wind cavity structure 320 to avoid obstructing the flow of air inside the wind cavity structure 320, and the position adjustment of the position sensor 410 is more convenient, ensuring that the wind cavity structure 320 is reliably in the first working state or the second working state.

[0108] The trigger member 310 is at least partially located outside the wind cavity structure 320 and is fixedly connected to the switching structure so as to move synchronously with the switching structure. The position sensor 410 is fixedly connected to the wind cavity structure 320 and is located on the movement path of the trigger member 310, thereby avoiding the position sensor 410 from moving synchronously with the switching structure and reducing the risk of damage to the position sensor 410.

[0109] Furthermore, in one embodiment, as shown in Figures 4 to 7, the switching structure can adopt a switching cylinder 340, which includes a switching cylinder body 341 and a first rotating shaft portion 342 coaxially connected to the switching cylinder body 341. The air chamber structure 320 is roughly cylindrical in shape, and the inner cavity of the air chamber structure 320 is adapted to the outer contour of the switching cylinder 340. The inner peripheral wall of the inner cavity of the air chamber structure 320 is in contact with the outer peripheral wall of the switching cylinder body 341. The switching cylinder body 341 can rotate around its axis under the guidance of the inner peripheral wall of the inner cavity of the air chamber structure 320. The first rotating shaft portion 342 partially extends out of the air chamber structure 320 through the inner cavity of the air chamber structure 320 to be connected to the driving member 330. With the above structure, the rotation of the switching cylinder 340 is more reliable, and when installing the switching cylinder 340, it only needs to be directly installed into the air chamber structure 320, without the need for an additional rotating connection structure between the two, further simplifying the overall structure.

[0110] The switching cylinder body 341 also has a closed inner cavity, and a number of openings 3411 connected to its inner cavity are provided on the outer wall of the switching cylinder body 341. During the rotation of the switching cylinder body 341, the outer wall of the switching cylinder body 341 can block the third connection port 323 and drive its opening 3411 to correspond to the first connection port 321 and the second connection port 322 to form a conductive first air duct 324 between the first connection port 321 and the second connection port 322, or the outer wall of the switching cylinder body 341 can block the second connection port 322 and drive its opening 3411 to correspond to the first connection port 321 and the third connection port 323 to form a conductive second air duct 325 between the first connection port 321 and the third connection port 323.

[0111] The above-mentioned docking port can be arranged on the axial and / or radial side walls of the wind cavity structure 320. In the present embodiment, it is preferably arranged on the radial side walls of the wind cavity structure 320 to shorten the path of the air duct and improve the suction efficiency. The wind cavity structure 320 has sufficient space to open the docking port and adjust the position of the docking port to improve the adaptability with the recycling box 120 and the base station 200. At the same time, it can also avoid the driving member 330 from obstructing the docking port and the components connected to the docking port.

[0112] Since the switching cylinder 340 is matched with the air cavity structure 320, the internal installation space of the air cavity structure 320 is small, and the position sensor 410 is inconvenient to install. Preferably, the position sensor 410 is located outside the air cavity structure 320 and is arranged on the axial side wall of the air cavity structure 320 away from the driving member 330, so that there is sufficient installation space to install the position sensor 410 and adjust the position of the position sensor 410. The trigger member 310 is arranged on the axial side wall of the switching cylinder 340 away from the first rotating shaft portion 342, and an avoidance hole 326 is provided on the axial side wall of the air cavity structure 320 away from the driving member 330. A portion of the trigger member 310 extends to the outside through the avoidance hole 326 to cooperate with the position sensor 410. The avoidance hole 326 is an arc-shaped hole extending along the movement path of the trigger member 310 to avoid obstructing the movement of the trigger member 310.

[0113] In this embodiment, the position sensor 410 includes a first position sensor 412 and a second position sensor 413. The first position sensor 412 and the second position sensor 413 are respectively arranged at the two ends of the avoidance hole 326 in the extension direction. The trigger member 310 is located between the first position sensor 412 and the second position sensor 413. When the trigger member 310 rotates along the first working direction by a first preset angle with the switching cylinder 340, it can trigger the first position sensor 412, and the circulation mechanism 300 is in the first working state. When the trigger member 310 rotates along the second working direction by a second preset angle with the switching cylinder 340, it can trigger the second position sensor 413, and the circulation mechanism 300 is in the second working state.

[0114] The first working direction and the second working direction may be opposite. For example, if the first working direction is clockwise, the second working direction is counterclockwise; and if the first working direction is counterclockwise, the second working direction is clockwise. Of course, the first working direction and the second working direction may also be the same. For example, if the first working direction is clockwise, the second working direction is also clockwise; and if the first working direction is counterclockwise, the second working direction is also counterclockwise.

[0115] The first preset angle and the second preset angle may be the same or different. Preferably, the first preset angle and the second preset angle are the same and may be set to an obtuse angle, for example, any angle such as 100° or 105°, or an acute angle, for example, 72° or 80°, or 90°.

[0116] Preferably, a plurality of positioning pins 327 are protruding from the axial sidewalls of the air cavity structure 320, and the position sensor 410 is provided with positioning holes 411 adapted to the positioning pins 327. The position sensor 410 can be sleeved onto the positioning pins 327 through the positioning holes 411, facilitating the positioning and installation of the position sensor 410. Each position sensor 410 is provided with at least two positioning holes 411, and the positioning holes 411 correspond one-to-one with the positioning pins 327 to prevent angular deviation of the position sensor 410. The position sensor 410 and the air cavity structure 320 can be fixed by a threaded connection, or the positioning holes 411 and the positioning pins 327 can be interference fit to achieve the fixation of the position sensor 410.

[0117] Furthermore, in another embodiment, as shown in Figures 8 to 11, the switching structure may also employ a baffle member 350. The baffle member 350 includes a baffle body 351 and a second rotating shaft portion 352 fixedly connected to the baffle body 351. The baffle body 351 and the second rotating shaft portion 352 may be integrally formed or separately formed and then assembled together. The second rotating shaft portion 352 is rotatably connected to the air cavity structure 320 and partially extends outside the air cavity structure 320. The driving member 330 is drivingly connected to the baffle body 351. The second rotating shaft portion 352, driven by the driving member 330, can drive the baffle body 351 to rotate to block the second connection port 322 or the third connection port 323. The above structure can make the circulation mechanism 300 compact, require less installation space, have good adaptability, shorten the air duct path, and effectively reduce losses during operation of the negative pressure device 110.

[0118] Due to the use of the baffle member 350, the internal space of the wind cavity structure 320 is larger. In one embodiment, the position sensor 410 can be fixed inside the wind cavity structure 320, and the trigger member 310 is located in the wind cavity structure 320 and is fixedly connected to the baffle body 351 and / or the second rotating shaft portion 352. The trigger member 310 can move with the baffle member 350 to trigger the position sensor 410 when in the first working state or the second working state.

[0119] Indeed, in another embodiment, the position sensor 410 is fixed outside the wind cavity structure 320, the trigger member 310 is at least partially located outside the wind cavity structure 320, and is fixedly connected to the second rotating shaft portion 352 so as to cooperate with the position sensor 410 to obtain the position state of the baffle member 350.

[0120] Furthermore, as shown in FIG14 , the present application also provides a control method for a cleaning system. The cleaning system includes a cleaning host 100 , a base station 200 , and a circulation mechanism 300 . The cleaning host 100 includes a negative pressure device 110 . The control method includes the following steps:

[0121] S100, in response to a sewage extraction signal, obtaining a position state of the circulation mechanism 300;

[0122] S200, controlling the circulation mechanism 300 to be in a first working state according to the position state, so that the circulation mechanism 300 conducts electricity between the base station 200 and the negative pressure device 110;

[0123] S300 , controlling the negative pressure device 110 to act on the base station 200 to suck the dirt from the cleaning host 100 to the base station 200 .

[0124] In one embodiment, the cleaning system is equipped with a sewage pumping button, which can be located on the cleaning host 100 or the base station 200. The sewage pumping button can trigger a sewage pumping signal to suck out sewage, thereby issuing a sewage pumping instruction. In another embodiment, when the cleaning host 100 and the base station 200 are docked, the sewage pumping instruction can be triggered and the sewage pumping signal can be issued, causing the cleaning system to automatically enter the sewage pumping state, simplifying operation.

[0125] After receiving the sewage extraction signal sent by the sewage extraction button or the sewage extraction signal automatically issued during docking, the current position state of the circulation mechanism 300 is obtained in response to the signal, and the circulation mechanism 300 is controlled to switch to the first working state according to the current position state. The base station 200 and the negative pressure device 110 are connected, so that the negative pressure device 110 can act on the base station 200, and then the dirt in the cleaning host 100 is sucked into the base station 200.

[0126] The control method of the cleaning system provided in the present application is that after receiving the sewage extraction signal, the cleaning system first obtains the position status of the circulation mechanism 300, and controls the circulation mechanism 300 to be in the first working state according to the position status, thereby improving the degree of intelligence, operational convenience and reliability of state switching; and the base station 200 provides suction force through the negative pressure device 110 on the cleaning host 100. There is no need to set up an additional negative pressure device 110 on the base station 200. The structure is simple, the base station 200 is easy to assemble and maintain, and the production cost is effectively reduced.

[0127] Furthermore, the position state includes a first position, and the first position is used to indicate that the circulation mechanism 300 is in the first working state. The above step S200 specifically includes:

[0128] S210, when it is determined that the position state is the first position, controlling the circulation mechanism 300 to remain stationary;

[0129] S220 , when the position state is not the first position, controlling the circulation mechanism 300 to move until the position state changes to the first position.

[0130] In this embodiment, the circulation mechanism 300 includes an air cavity structure 320 and a switching structure movably connected to the air cavity structure 320. The switching structure can move to a first position relative to the air cavity structure 320. The switch structure determines whether it needs to move based on the detected position of the switching structure. When the switching structure is in the first position, the circulation mechanism 300 is determined to be in the first working state, and the switching structure is controlled to remain stationary, and the sewage extraction process is then executed. When the switching structure is not in the first position, the circulation mechanism 300 is determined to be not in the first working state, and the switching structure is controlled to move along a predetermined path until it moves to the first position, where it remains stationary, and the sewage extraction process is then executed.

[0131] The position state can be detected by a detection device, for example, a position sensor 410 is set on one of the first position or switching structure, and a trigger member 310 is set on the other, so as to trigger the position sensor 410 when the switching structure moves to the first position, thereby obtaining a detection signal.

[0132] Preferably, the cleaning host 100 further includes a recycling box 120. As shown in FIG15 , the control method further includes:

[0133] S400, in response to the dirt suction signal, obtaining the position state of the circulation mechanism 300;

[0134] S500, controlling the circulation mechanism 300 to be in the second working state according to the position state, so that the circulation mechanism 300 conducts the recovery box 120 and the negative pressure device 110;

[0135] S600 , controlling the negative pressure device 110 to act on the recovery box 120 to suck the external dirt of the cleaning host 100 into the recovery box 120 .

[0136] In this embodiment, the cleaning system is equipped with a dirt suction button, which is preferably set on the cleaning host 100 to facilitate real-time operation by the user during the use of the cleaning host 100. The dirt suction button can trigger a dirt suction signal for the recovery box 120 to suck the dirt to issue a dirt suction instruction.

[0137] After receiving the suction signal sent by the suction button, the current position state of the circulation mechanism 300 is obtained in response to the signal, and the circulation mechanism 300 is controlled to switch to the second working state according to the current position state. The negative pressure device 110 and the recovery box 120 are connected, so that the negative pressure device 110 can act on the recovery box 120, and then the external dirt generated during the operation of the cleaning host 100 is sucked into the recovery box 120.

[0138] Furthermore, the position state further includes a second position, and the second position is used to indicate that the circulation mechanism 300 is in the second working state. The above step S500 specifically includes:

[0139] S510, when it is determined that the position state is the second position, controlling the circulation mechanism 300 to remain stationary;

[0140] S520 : When the position state is not the second position, control the circulation mechanism 300 to move until the position state changes to the second position.

[0141] In this embodiment, the switching structure can move relative to the air cavity structure 320 to a second position. The detected position of the switching structure determines whether it needs to move. When the switching structure is in the second position, it is determined that the circulation mechanism 300 is in the second operating state. The switching structure is controlled to remain stationary, and the sewage suction process is then executed. When the switching structure is not in the second position, it is determined that the circulation mechanism 300 is not in the second operating state. The switching structure is controlled to move along a predetermined path until it reaches the second position, remains stationary, and the sewage suction process is then executed.

[0142] Furthermore, the detection method of the second position is the same as the detection method of the first position. For example, when the trigger member 310 is set on the switching structure, another position sensor 410 can be set at the second position, or when a trigger member 310 is set at the first position, another trigger member 310 can be set at the second position, so that when the switching structure moves to the second position, the position sensor 410 can trigger another trigger member 310 to obtain a detection signal.

[0143] Preferably, after issuing a suction command or a pumping command, a corresponding voice reminder message can be issued, and when the circulation mechanism 300 completes the switching of the working state, a corresponding voice reminder message can also be issued to remind the user of the current working mode of the cleaning system, thereby improving the user's experience.

[0144] To achieve the above-mentioned purpose, as shown in FIG16 , the present application further provides a control device for a cleaning system, comprising an acquisition module 510, a position control module 520, and a negative pressure control module 530. The acquisition module 510 is used to acquire the position state of the circulation mechanism 300 in response to the sewage extraction signal. The acquisition module 510 may adopt a position sensor 410 to directly detect the position state of the switching structure of the circulation mechanism 300; alternatively, the acquisition module 510 may adopt an encoder connected to the signal of the driving member 330 of the circulation mechanism 300 to indirectly acquire the position state of the switching structure by acquiring the forward and reverse rotation and rotation angle of the driving member 330.

[0145] The position control module 520 is a controller structure that is signal-connected to the acquisition module 510 and the circulation mechanism 300. The position control module 520 is used to control the circulation mechanism 300 to be in the first operating state based on the position state, so that the circulation mechanism 300 is connected to the base station 200 and the negative pressure device 110. The negative pressure control module 530 is a controller structure that is signal-connected to the negative pressure device 110 and the position control module 520. When the position control module 520 controls the circulation mechanism 300 to be in the first operating state, the negative pressure control module 530 receives the signal and is used to control the negative pressure device 110 to act on the base station 200, thereby sucking dirt from the cleaning host 100 to the base station 200.

[0146] In addition, the acquisition module 510 can also be used to respond to the dirt suction signal to obtain the position status of the circulation mechanism 300. The position control module 520 is used to control the circulation mechanism 300 to be in the second working state according to the position status, so that the circulation mechanism 300 is connected to the negative pressure device 110 and the recovery box 120. The negative pressure control module 530 is used to control the negative pressure device 110 to act on the recovery box 120 to suck external dirt into the recovery box 120.

[0147] Preferably, the control device further comprises a voice playing module for playing voice reminder information, for playing voice reminder messages to remind the user of the current working mode of the cleaning system.

[0148] In order to achieve the above-mentioned purpose, the present application provides a computer-readable storage medium storing a computer program, which includes a self-cleaning program and a sewage discharge program. The computer program is loaded and executed by the processor of the control device to implement the control method of the above-mentioned cleaning system.

[0149] The processor can be provided independently of the cleaning host 100 and the base station 200, or can be provided in the cleaning host 100 and / or the base station 200. In other words, the control device can be a control structure in the cleaning host 100 or the base station 200, or a control structure coordinated by the cleaning host 100 and the base station 200, or a terminal independent of the cleaning host 100 and the base station 200, which can be, but is not limited to, a mobile phone, a tablet computer, a portable wearable device, etc.

[0150] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
