[0006] The present disclosure relates to the technical field of cleaning tools, and in particular to a cleaning system and a control method and a control device thereof. Background Art

[0007] At present, the cleaning system usually includes cleaning equipment (such as scrubbers and sweepers) and a base station. The cleaning equipment and the base station can use a dual-fan structure for sewage treatment.

[0008] More specifically, the cleaning device may be provided with a first fan and a first sewage tank, and the base station may be provided with a second fan and a second sewage tank. While the cleaning device is mopping or performing self-cleaning operations, the first fan on the cleaning device is turned on, creating a negative pressure in the first sewage tank through the first fan, thereby sucking sewage generated by cleaning components (such as a roller brush, mopping turntable, etc.) into the first sewage tank. After the cleaning device is docked to the base station, the second fan on the base station is turned on, creating a negative pressure in the second sewage tank through the second fan, thereby sucking sewage from the first sewage tank into the second sewage tank, thereby automatically cleaning the first sewage tank on the cleaning device. However, the above-mentioned dual-fan structure is relatively complex, costly, and inconvenient to install and maintain.

In one embodiment, a connecting air duct can be provided between the suction device 3 and the base station 200, for example, by providing an external connecting pipe to connect the suction device 3 and the base station 200; or, alternatively, by providing corresponding docking components on the base station 200 and the cleaning apparatus 100. The connection and blocking of the connecting air duct between the suction device 3 and the base station 200 can be achieved.

[0157] Preferably, as shown in Figures 2, 5, 12, and 14, the cleaning system 1000 further includes a state switching structure 4 / 4', which has a first operating state that connects the base station 200 and the suction device 3. After the cleaning device 100 is connected to the base station 200, the state switching structure 4 / 4' adjusts its state to enter the first operating state, thereby connecting the suction device 3 and the base station 200. The suction force generated by the suction device 3 can enter the base station 200 through the state switching structure 4 / 4', creating a negative pressure inside the base station 200.

[0158] Specifically, the base station 200 may include a storage chamber, or the base station 200 may have at least a sewage discharge channel for sewage discharge, through which the sewage in the sewage collecting chamber 2 of the cleaning device 100 can be conducted to be transferred to the storage chamber or directly transferred to a sewage treatment site (such as a sewer). When the cleaning device 100 is in the sewage discharge state, the suction device 2 can be connected to the base station 200 so that the sewage in the cleaning device 100 can be sucked into the storage chamber or sewage discharge channel. Specifically, the state switching structure 4 / 4' can be adjusted to the first working state, and the suction device 3 can form a negative pressure in the storage chamber or sewage discharge channel of the base station 200. The sewage in the sewage collecting chamber 2 of the cleaning device 100 can enter the sewage discharge channel under the action of the suction force, and then enter the storage chamber or sewer. Among them, the storage chamber of the base station can store 1.5 liters to 2 liters of water. The large water storage capacity prevents the sewage in the storage chamber from being blocked when it is discharged into the sewer.

[0159] Among them, the storage chamber and the sewage collecting chamber 2 are connected through the first sewage outlet on the base station 200 and the second sewage outlet on the cleaning equipment 100. The second sewage outlet is connected to the sewage collecting chamber 2. The second sewage outlet can be set on the outer surface of the cleaning equipment 100, and a cover is provided at the second sewage outlet. When the cleaning equipment 100 is in a non-sewage discharge state, the cover is pressed at the second sewage outlet by a torsion spring to prevent the sewage in the sewage collecting chamber 2 from overflowing. When the cleaning equipment 100 is docked with the base station 200 for sewage discharge, the cover can be sucked open under the action of the suction force of the suction device 3, so that the sewage in the sewage collecting chamber 2 can enter the first sewage outlet from the second sewage outlet and enter the storage chamber.

[0160] Alternatively, a cleaning tank may be provided on the base station 200, which can be used to clean the cleaning parts (such as roller brushes, rags, etc.) on the cleaning device 100. The sewage, debris, and other dirt generated during the cleaning process will remain in the cleaning tank. The cleaning tank is connected to the sewage discharge channel of the base station 200. When the cleaning device 100 is placed on the base station 200 and the sewage collecting chamber 2 is cleaned, the cleaning parts can be cleaned at the same time, so that the dirt in the sewage collecting chamber 2 and the dirt in the cleaning tank can be sucked into the sewage discharge channel. There is no need to set up an additional device to provide suction power on the base station 200. While the functions of the base station 200 can be more diversified, the structure of the base station 200 is simpler, the cost is lower, and it is more convenient to use.

[0161] It can be understood that the state switching structure 4 / 4' can be set on the cleaning device 100, or can be set on the base station 200, or the state switching structure 4 / 4' can be an independent structure to be set independently of the cleaning device 100 and the base station 200, or the state switching structure 4 / 4' can be provided with multiple sets, which are respectively located on the cleaning device 100 and the base station 200, so as to ensure that the suction device 3 and the base station 200 can be connected through the state switching structure 4 / 4'.

[0162] Preferably, again in conjunction with Figures 2, 5, 12, and 14, the state switching structure 4 / 4' is disposed on the cleaning device 100, and the state switching structure 4 / 4' is disposed closer to the suction device 3. The suction force generated by the suction device 3 can better enter the state switching structure 4 / 4', resulting in less power loss, greater suction force provided, and greater suction force generated within the base station 200, thereby improving the sewage discharge effect. The following will use the state switching structure 4 / 4' disposed on the cleaning device 100 as an example to specifically describe the specific structure of the cleaning system 1000. Other embodiments can be implemented with reference to the adaptability and will not be described one by one here.

[0163] It can be understood that the cleaning device 100 also has a cleaning state in which cleaning work can be performed normally. For example, the cleaning device 100 can be used to clean dirt on the ground, walls or glass. Specifically, as shown in Figures 5 to 7, the cleaning device 100 includes a dirt collecting chamber 2, and the above-mentioned state switching structure 4 / 4' also has a second working state in which the suction device 3 and the dirt collecting chamber 2 are connected. When the state switching structure 4 / 4' is in the second working state, the state switching structure 4 / 4' can connect the suction device 3 and the dirt collecting chamber 2, and the suction force generated by the suction device 3 causes a negative pressure to be formed in the dirt collecting chamber 2. Moreover, the dirt collecting chamber 2 is also connected to the dirt suction port on the cleaning device 100. When a negative pressure is formed in the dirt collecting chamber 2, external dirt can be sucked into the cleaning device 100 through the dirt suction port and enter the dirt collecting chamber 2 for storage. After the cleaning device 100 has finished cleaning, the cleaning device 100 is connected to the base station 200, so that the state switching structure 4 / 4' enters the first working state to connect the suction device 3 and the base station 200. Under the action of the suction device 3 of the cleaning device 100, the dirt in the dirt collecting chamber 2 can be sucked into the base station 200 to complete the cleaning of the dirt collecting chamber 2 of the cleaning device 100. The entire cleaning and sewage discharge process does not require the user to manually clean the dirt, which is more labor-saving, not easy to dirty the user's hands, and the user experience is also better.

[0164] Specifically, the suction device 3 may include a fan and a fan housing. The fan may be configured as an axial flow fan or a centrifugal fan. The fan housing has a receiving cavity, and the fan is disposed within the receiving cavity. The fan housing is in communication with the device body 1. The fan housing has an air inlet connected to the air inlet end of the fan, and an air outlet connected to the air outlet end of the fan. When the suction device 3 is connected to the base station 200, the air inlet on the fan housing is connected to the base station 200 and the sewage collecting chamber 2, so as to facilitate the fixing of the fan and facilitate the establishment of electrical connection between the base station 200 and the sewage collecting chamber 2.

[0165] Of course, the state switching structure 4 / 4' may also have other states, such as a waiting state or an initial state, so as to be in a transition or preparation position for entering the first working state or the second working state. Among them, when the state switching structure 4 / 4' is in the first working state, the suction device 3 and the base station 200 are in a conductive state. When the state switching structure 4 / 4' is not in the first working state, and the state switching structure 4 / 4' is in the second working state or other states, the suction device 3 and the base station 200 may be in a blocked state. When the cleaning device 100 is not performing sewage treatment, the communication path between the suction device 3 and the base station 200 is blocked. On the one hand, it can avoid the outflow of dirt from the sewage collecting chamber 2 of the cleaning device 100 when sewage is not discharged, causing blockage or secondary pollution of the pipeline. On the other hand, it can avoid the diversion of airflow caused by part of the airflow entering the base station 200 when the cleaning device 100 is performing cleaning work, thereby affecting the cleaning effect of the cleaning device 100.

[0166] Preferably, in combination with Figures 2 to 4, the state switching structure 4 / 4' includes a first opening structure and a first shielding structure 424. When the state switching structure 4 / 4' is in the first working state, the first opening structure connects the base station 200 and the suction device 3. When it is in the second working state, the first shielding structure 424 blocks the base station 200 and the suction device 3. The base station 200 and the suction device 3 can be connected through the first opening structure, and the base station 200 and the suction device 3 can be blocked through the first shielding structure 424, so that the connection path between the base station 200 and the suction device 3 can be better adjusted and controlled to ensure better sewage discharge effect.

[0167] Furthermore, in combination with FIG3 and FIG13 , the first opening structure includes a first opening 4111 / 4111' and a second opening 4112 / 4112'. When in the first working state, the first opening 4111 / 4111' is connected to the suction device 3, and the second opening 4112 / 4112' is connected to the base station 200. The suction device 3 and the base station 200 are connected through the first opening 4111 / 4111' and the second opening 4112 / 4112'. Under the action of the suction device 3, the suction airflow can enter the base station 200 through the sewage collecting chamber 2, and then flow to the first opening 4111 / 4111' through the second opening 4112 / 4112' to enter the suction device 3, thereby achieving the cleaning of the sewage collecting chamber 2 by the base station 200. The airflow path is simpler, the wind resistance is smaller, and the efficiency is higher. In the second operating state, the first shielding structure 424 blocks the second opening 4112 / 4112' from communicating with the base station 200, thereby forming a blockage between the base station 200 and the suction device 3. This prevents the base station 200 and the suction device 3 from remaining in communication when the cleaning device 100 does not need to discharge waste, thereby causing airflow diversion and affecting the cleaning effect of the cleaning device 100. In the second operating state, blocking the passage between the base station 200 and the suction device 3 can better protect the communication path between the base station 200 and the suction device 3, allowing the cleaning system 1000 to maintain an optimal cleaning state.

[0168] It can be understood that the method of achieving the connection between the base station 200 and the suction device 3 and the blockage between the base station 200 and the suction device 3 through the state switching structure 4 / 4' is not limited to the above-mentioned one. In another embodiment, the state switching structure 4 / 4' may include at least one first barrier, and at least one first barrier is arranged on the communication path between the base station 200 and the suction device 3. Each first barrier may be movably arranged to open and close the communication path between the suction device 3 and the base station 200. When each first barrier is in the open state, the communication path between the base station 200 and the suction device 3 is in the conductive state, and when each first barrier is in the closed state, the communication path between the base station 200 and the suction device 3 is in the blocked state. By controlling the state of each first barrier, the conduction and blockage of the communication path between the base station 200 and the suction device 3 can be controlled. One first barrier can be provided, which is convenient to control and simple to operate. Alternatively, multiple first barriers may be provided. These multiple barriers form multiple blockages on the communication path between the base station 200 and the suction device 3, resulting in a better sealing effect. The first barrier may be configured as a movable barrier plate, a mechanical valve, or a solenoid valve. The first barrier may be manually moved or driven by a driver.

[0169] When the state switching structure 4 / 4' is in the second working state, the suction device 3 and the dirt collecting chamber 2 are in a conducting state. When the state switching structure 4 / 4' is not in the second working state, for example, when the state switching structure 4 / 4' is in the first working state or other states (such as waiting state, or initial state), the suction device 3 and the dirt collecting chamber 2 may be in a blocked state. When the cleaning device 100 is not performing cleaning work, the connecting path between the suction device 3 and the dirt collecting chamber 2 is blocked to prevent the cleaning device 100 from continuously sucking dirt into the dirt collecting chamber 2 when performing sewage treatment, causing the sewage discharge work to continue for too long, and part of the airflow will enter the sewage collecting chamber 2 and cause the airflow to be diverted, so that the suction force of the base station 200 is reduced, thereby affecting the sewage discharge effect.

[0170] Preferably, in combination with Figures 6 to 9, the state switching structure 4 / 4' includes a second opening structure and a second shielding structure 425. When the state switching structure 4 / 4' is in the second working state, the second opening structure connects the dirt collecting chamber 2 and the suction device 3. When it is in the first working state, the second shielding structure 425 blocks the dirt collecting chamber 2 and the suction device 3. The connection between the dirt collecting chamber 2 and the suction device 3 can be achieved through the second opening structure, and the blocking of the dirt collecting chamber 2 and the suction device 3 can be achieved through the second shielding structure 425. The connecting path between the dirt collecting chamber 2 and the suction device 3 can be better adjusted and controlled to realize the cleaning function of the cleaning equipment 100.

[0171] Further, in combination with Figures 7 and 15, the second opening structure includes a third opening 4113 / 4113' and a fourth opening. When in the second working state, the fourth opening is connected to the suction device 3, and the third opening 4113 / 4113' is connected to the sewage collecting chamber 2. The third opening 4113 / 4113' and the fourth opening are connected to conduct the suction device 3 and the sewage collecting chamber 2. Under the action of the suction device 3, the suction airflow can enter the sewage collecting chamber 2 through the sewage suction port of the cleaning equipment 100, and the clean airflow after filtration can enter the suction device 3, thereby realizing the cleaning work of the cleaning equipment 100. When in the first working state, the second shielding structure 425 can block the third opening 4113 / 4113' and the dirt collecting chamber 2 from being connected, so that a blockage is formed between the dirt collecting chamber 2 and the suction device 3, thereby preventing the dirt collecting chamber 2 and the suction device 3 from being in a connected state when the cleaning equipment 100 stops cleaning, causing air flow diversion and affecting the self-cleaning of the dirt collecting chamber 2 of the cleaning equipment 100.

[0172] Similarly, the manner in which the connection between the dirt collecting chamber 2 and the suction device 3 and the blockage between the dirt collecting chamber 2 and the suction device 3 are achieved through the state switching structure 4 / 4' is not limited to the one described above. In another embodiment, the state switching structure 4 / 4' may include at least one second barrier, and at least one second barrier is provided on the connection path between the dirt collecting chamber 2 and the suction device 3. Wherein, each second barrier may be movably provided to open and close the connection path between the suction device 3 and the dirt collecting chamber 2. When each second barrier is in the open state, the connection path between the dirt collecting chamber 2 and the suction device 3 is in the conducting state, and when each second barrier is in the closed state, the connection path between the dirt collecting chamber 2 and the suction device 3 is in the blocked state. By controlling the state of each second barrier to control the connection and blockage of the connection path between the dirt collecting chamber 2 and the suction device 3, one second barrier may be provided, which is convenient to control and simple to operate. Alternatively, multiple second barriers may be provided. These multiple barriers form multiple blockages on the communication path between the dirt collection chamber 2 and the suction device 3, resulting in a better sealing effect. The second barrier may be configured as a movable barrier plate, a mechanical valve, or a solenoid valve. The second barrier may be manually moved or driven by a driver.

[0173] Optionally, the first barrier member and the second barrier member may be the same.

[0174] Optionally, the first barrier on the communication path between the base station 200 and the suction device 3 and the second barrier on the communication path between the dirt collecting chamber 2 and the suction device 3 can block one of the two paths through an external driving device, thereby making the other path conductive.

[0175] In addition, under certain circumstances, when one of the communication path between the suction device 3 and the base station 200 and the communication path between the suction device 3 and the sewage collecting chamber 2 is in a conductive state, the other one may also be in a conductive state, that is, the suction device 3 is conductive to the base station 200 and the sewage collecting chamber 2. Specifically, if the suction force of the suction device 3 is large enough, and the suction force formed in the communication path between the suction device 3 and the sewage collecting chamber 2 is equal to the suction force formed in the communication path between the suction device 3 and the sewage collecting chamber 2, the cleaning device 100 can be in two working states at the same time. While the suction force for sucking external dirt can be formed in the sewage collecting chamber 2, the dirt in the sewage collecting chamber 2 can be sucked out in the base station 200, so that the cleaning device 100 can suck dirt and discharge dirt at the same time.

[0176] Specifically, when there is a lot of external dirt and it is heavy, if the cleaning work is performed by the cleaning device 100, since the volume of the cleaning device 100 is relatively small, the volume of the dirt collecting chamber 2 is also relatively small. If the normal cleaning method is used, the dirt collecting chamber 2 of the cleaning device 100 is easy to fill up. When in use, the cleaning device 100 needs to be placed on the base station 200 for self-cleaning many times, and each time the cleaning device 100 performs self-cleaning, it is necessary to wait for a certain period of time, which makes the operation time-consuming and labor-intensive. Therefore, by connecting the cleaning device 100 to the base station 200, and making the suction device 3 connected to the base station 200 and the dirt collecting chamber 2, the dirt sucked into the dirt collecting chamber 2 by the cleaning device 100 can be sucked out in time through the base station 200, without the need to frequently move the cleaning device 100, and without waiting for the cleaning device 100 to perform self-cleaning. Obviously, the operation is more time-saving and labor-saving. Preferably, the air outlet connecting the sewage collecting chamber 2 and the suction device 3 and the sewage outlet connecting the sewage collecting chamber 2 and the base station 200 can be set on the same side of the sewage collecting chamber 2. Therefore, the airflow entering the sewage collecting chamber 2 can flow in the same direction. A filter component can be provided at the air outlet, and the airflow can be filtered by the filter component so that the clean airflow can be discharged through the air outlet to enter the suction device 3, while the dirt can be discharged through the sewage outlet to enter the base station 200, thereby achieving sewage suction and discharge at the same time.

[0177] In this case, the base station 200 can be configured to be movable so that it can be moved along with the cleaning device 100, thereby extending the cleaning range. Alternatively, a longer telescopic connecting pipe can be provided between the base station 200 and the cleaning device 100 to better connect the base station 200 and the cleaning device 100, making it easier to clean when the amount of dirt is large. However, this configuration requires strict control of the suction air flow generated by the suction device 3 to ensure a more balanced air flow entering the base station 200 and the dirt collection chamber 2, thereby achieving a working state of simultaneously sucking and discharging dirt.

[0178] In a normal household cleaning environment, preferably, the state switching structure 4 / 4' can make the cleaning device 100 work in only one of the working states. Among them, when the state switching structure 4 / 4' is in the first working state, the state switching structure 4 / 4' blocks the flow path between the suction device 3 and the dirt collecting chamber 2; when the state switching structure 4 / 4' is in the second working state, the state switching structure 4 / 4' blocks the flow path between the suction device 3 and the base station 200. The state switching structure 4 / 4' can simultaneously realize the conduction of one flow path and the blocking of another flow path, making the conduction and blocking operations simpler, and such a setting method makes the two working states of the cleaning device 100 not appear at the same time, which can better protect the cleaning device 100. The suction device 3 can selectively connect the base station 200 and the dirt collecting chamber 2, so that the suction force is more concentrated, so the cleaning effect and self-cleaning effect of the cleaning device 100 will be better. Moreover, in a normal household cleaning environment, the power requirement of the suction device 3 is lower than that in a specific environment, so the cost of the suction device 3 is lower, and the structure of the entire cleaning device 100 can be simpler and the cost is also lower.

[0179] Furthermore, in conjunction with Figures 3 and 13 , when in the first working state, the first opening 4111 / 4111' is connected to the suction device 3, the second opening 4112 / 4112' is connected to the base station 200, and the first shielding structure 424 blocks the communication path between the third opening 4113 / 4113' and the dirt collecting chamber 2. At this time, the suction force generated by the suction device 3 enables the base station 200 to suck out the dirt in the dirt collecting chamber 2 of the cleaning device 100, thereby achieving self-cleaning of the cleaning device 100. In the second working state, in conjunction with Figures 3 and 4 , the fourth opening is connected to the suction device 3, the third opening 4113 / 4113' is connected to the dirt collecting chamber 2, and the second shielding structure 425 blocks the communication path between the second opening 4112 / 4112' and the base station 200. At this time, the suction force generated by the suction device 3 enables the cleaning device 100 to suck external dirt into the dirt collecting chamber 2, thereby achieving the cleaning work of the cleaning device 100 on the outside. The switching between the two working states of the cleaning device 100 is achieved by converting the state of the state switching structure 4 / 4'. The cleaning device 100 can perform the cleaning work normally while also providing cleaning power for its own self-cleaning work. The function of the cleaning device 100 is more powerful, and the structure of the base station 200 is simpler and the cost is lower, thereby lowering the cost of the entire cleaning system 1000.

[0180] It can be understood that, corresponding to each setting mode of the above-mentioned state switching structure 4 / 4', the state switching structure 4 / 4' can be correspondingly provided with a plurality of movement modes. For example, when the state switching structure 4 / 4' includes a first barrier, the first barrier may have a linear reciprocating stroke, or a rotation stroke, or an arc movement stroke, or a combination of two of these movement modes, etc. Thus, the various setting forms and the various movement modes of the state switching structure 4 / 4' can be implemented in combination with each other, including but not limited to the embodiments listed in the present disclosure. Specifically, it can be reasonably set according to the specific structure and size of the cleaning system 1000, which will not be described in detail here. The preferred implementation of the state switching structure 4 / 4' will be described below in conjunction with specific embodiments.

[0181] Preferably, the state switching structure 4 / 4' is rotatably provided on the cleaning device 100, and the state switching structure 4 / 4' is rotated to switch between the first working state and the second working state, which makes state adjustment more convenient and easy to control.

[0182] Specifically, in one embodiment, the first opening 4111 / 4111', the second opening 4112 / 4112', the third opening 4113 / 4113' and the fourth opening may be arranged on the same circumferential surface so that the channel between the first opening 4111 / 4111' and the second opening 4112 / 4112' and the channel between the third opening 4113 / 4113' and the fourth opening are non-intersecting. When the first opening 4111 / 4111' is connected to the suction device 3 and the second opening 4112 / 4112' is connected to the base station 200, the third opening 4113 / 4113' is offset from the sewage collecting chamber 2, and the fourth opening is offset from the suction device 3; when the third opening 4113 / 4113' is connected to the sewage collecting chamber 2 and the fourth opening is connected to the suction device 3, the first opening 4111 / 4111' is offset from the suction device 3, and the second opening 4112 / 4112' is offset from the base station 200. By switching between different openings, one of the channels is in a connected state with the suction device 3.

[0183] In another embodiment, at least one of the first opening 4111 / 4111', the second opening 4112 / 4112', the third opening 4113 / 4113', and the fourth opening is spaced apart from the other openings along the axial direction of the circumferential surface, such that one channel is disposed radially along the circumferential surface, while another channel is disposed axially along the circumferential surface. Specifically, the channel between the first opening 4111 / 4111' and the second opening 4112 / 4112' and the channel between the third opening 4113 / 4113' and the fourth opening can be arranged in an intersecting manner, thereby reducing the diameter of the circumferential surface and achieving a more compact structure.

[0184] Preferably, the first opening 4111 / 4111 ′ and the fourth opening may be provided integrally to reduce the number of openings communicating with the suction device 3 , thereby making the structure of the state switching structure 4 / 4 ′ simpler.

[0185] Furthermore, the first opening 4111, the third opening 4113, the second shielding structure 425, the first shielding structure 424, and the second opening 4112 are sequentially arranged at intervals along the circumference. When in the first working state, the first opening 4111 and the suction device 3 are in a relative connection state, the third opening 4113 is staggered with the sewage collecting chamber 2, and the second shielding structure 425 is arranged to block the connection between the sewage collecting chamber 2 and the state switching structure 4 / 4', the second opening 4112 is in a relative connection state with the base station 200, and the cleaning device 100 is in a sewage discharge state; when in the second working state, the first opening 4111 can be rotated to be staggered with the suction device 3, the second opening 4112 is in relative connection with the suction device 3, the third opening 4113 is in relative connection with the sewage collecting chamber 2, the first shielding structure 424 blocks the connection between the base station 200 and the state switching structure 4 / 4', and the cleaning device 100 enters the cleaning working state. By rotating the state switching structure 4 / 4', different openings are adjusted to be connected with the base station 200 and the sewage collecting chamber 2, thereby realizing the switching between the two working states, and the adjustment is simple and convenient.

[0186] Moreover, the cleaning system 1000 further includes a switching drive component 43 / 43', which is connected to the state switching structure 4 / 4' and is used to drive the state switching structure 4 / 4' to rotate, making the state switching of the state switching structure 4 / 4' more labor-saving and the operation of the cleaning device 100 more intelligent.

[0187] The switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate, and when the state switching structure 4 / 4' rotates by a first preset angle, it can enter the first working state. Specifically, the switching drive component 43 / 43' can have an initial position or a waiting position, and the switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate by a first preset angle, so that the state switching structure 4 / 4' can rotate from the initial position or the waiting position to the first working state. Alternatively, the state switching structure 4 / 4' only rotates between the first working state and the second working state, and the switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate, so that the state switching structure 4 / 4' can switch from the second working state to the first working state after rotating by the first preset angle.

[0188] Similarly, by driving the state switching structure 4 / 4' to rotate by the switching drive component 43 / 43', the state switching structure 4 / 4' can enter the second working state when it rotates by a second preset angle. The switching drive component 43 / 43' can have an initial position or a waiting position, and by driving the state switching structure 4 / 4' by the switching drive component 43 / 43', the state switching structure 4 / 4' can rotate from the initial position or the waiting position to the second working state when it rotates by the second preset angle. Alternatively, the state switching structure 4 / 4' only moves between the first working state and the second working state, and by driving the state switching structure 4 / 4' by the switching drive component 43 / 43', the state switching structure 4 / 4' can switch from the first working state to the second working state after rotating by the second preset angle.

[0189] Preferably, the switching drive component 43 / 43' can drive the state switching structure 4 / 4' to rotate, so that the state switching structure 4 / 4' can switch between the first working state and the second working state, with a smaller rotation stroke and a simpler structure.

[0190] In which, the state switching structure 4 / 4' may have a rotation stroke along the first direction and / or a rotation stroke along the second direction, wherein the first direction and the second direction are arranged in opposite directions, that is, when the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. Under the drive of the switching drive component 43 / 43', the state switching structure 4 / 4' can continuously rotate in one direction to be in the first working state and the second working state respectively. Alternatively, when the switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate in the first direction, the state switching structure 4 / 4' can switch from the first working state to the second working state, and when the switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate in the second direction, the state switching structure 4 / 4' switches from the second working state to the first working state.

[0191] It is understood that the first preset angle and the second preset angle may be the same or different. When the state switching structure 4 / 4' has a rotational travel in the first direction and the second direction, it reciprocates between the first working state and the second working state. Preferably, the first preset angle and the second preset angle are the same. They can be set to obtuse angles, such as 100°, 105°, or any other angle, or to acute angles, such as 72°, 80°, or 90°.

[0192] When the switching drive component 43 / 43' drives the state switching structure 4 / 4' to rotate continuously in the same direction, the first preset angle and the second preset angle can be set to be equal or different. That is, the first position of the state switching structure 4 / 4' in the first working state and the second position of the state switching structure 4 / 4' in the second working state are on the same circumferential surface. When the first position and the second position are set relative to each other along the radial direction of the circumferential surface, the first preset angle and the second preset angle are equal and can both be 180°. When the angle between the first position and the second position is less than 180°, such as when the first preset angle is θ, the second preset angle is 360°-θ, so as to ensure that the state switching structure 4 / 4' can rotate continuously in the same direction to be in the first working state and the second working state respectively. Among them, the rotation direction and rotation angle of the state switching structure 4 / 4' are not specifically limited and can be reasonably set according to the internal structure of different cleaning equipment 100.

[0193] As for the state switching structure 4 / 4', in one embodiment, in combination with Figures 8, 9, 16 and 18, the state switching structure 4 / 4' includes a reversing shell 41 / 41' and a reversing body, wherein the reversing shell 41 / 41' has a first air duct connecting the suction device 3 and the base station 200, and a second air duct connecting the suction device 3 and the sewage collecting chamber 2; the reversing body is rotatably arranged in the reversing shell 41 / 41' and is driven and connected to the switching drive component 43 / 43'; the switching drive component 43 / 43' drives the reversing body to rotate, so that the reversing body can conduct the first air duct and block the second air duct to be in the first working state, and the reversing body can conduct the second air duct and block the first air duct to be in the second working state, and the switching between the first working state and the second working state is realized by the rotation of the reversing body.

[0194] Among them, the reversing body can be integrated with the fan housing, so that there are fewer assembly parts and the assembly is more convenient, so that the suction device 3 and the state switching structure 4 / 4' can be fixed together in the equipment body 1, the assembly accuracy is higher, and it is not easy to produce abnormal noise when the cleaning equipment 100 is working.

[0195] Alternatively, the reversing body and the fan housing are detachably arranged so that when the fan is assembled with the fan housing, the state switching structure 4 / 4' can be assembled at the same time, which increases the overall assembly efficiency and facilitates maintenance.

[0196] Specifically, as shown in Figures 9 and 18, the first opening 4111 / 4111', the second opening 4112 / 4112' and the third opening 4113 / 4113' are provided on the reversing housing 41 / 41', the first opening 4111 / 4111' is communicated with the suction device 3, the second opening 4112 / 4112' is communicated with the base station 200, and the third opening 4113 / 4113' is communicated with the sewage collecting chamber 2; the first channel and the second channel, as well as the third opening 4113 / 4113' are formed on the reversing body. A shielding structure 424 and a second shielding structure 425; when in the first working state, the first channel connects the first opening 4111 / 4111' and the second opening 4112 / 4112', and the second shielding structure 425 blocks the third opening 4113 / 4113'; when in the second working state, the second channel connects the first opening 4111 / 4111' and the third opening 4113 / 4113', and the first shielding structure 424 blocks the second opening 4112 / 4112'. By rotating the reversing body relative to the reversing housing 41, the first channel on the reversing body connects to the first opening 4111 / 4111' and the second opening 4112 / 4112', allowing the suction device 3 to communicate with the base station 200, and a negative pressure can be formed in the base station 200 to suck out the dirt in the dirt collecting chamber 2 of the cleaning device 100. By rotating the reversing body relative to the reversing housing 41 / 41', the second channel on the reversing body connects to the first opening 4111 / 4111' and the third opening 4113 / 4113', allowing the suction device 3 to communicate with the dirt collecting chamber 2, and external dirt can enter the dirt collecting chamber 2 through the dirt suction port of the cleaning device 100, thereby completing the cleaning of external dirt. Switching between the first working state and the second working state is more convenient, and there will be no state where the suction device 3 is connected to or blocked with both the base station 200 and the dirt collecting chamber 2, which can better protect the suction device 3 and the cleaning device 100.

[0197] Furthermore, as shown in Figure 9, the reversing body includes a reversing cylinder 42, and a first guide port 421, a second guide port 422 and a third guide port 423 arranged on the peripheral side wall of the reversing cylinder 42, and the above-mentioned first shielding structure 424 and the second shielding structure 425 are also arranged on the peripheral side wall of the reversing cylinder 42.

[0198] In one embodiment, the first guide port 421 , the second guide port 422 and the third guide port 423 are spaced apart along the circumference of the reversing cylinder 42 , and the first opening 4111 , the second opening 4112 and the third opening 4113 are spaced apart along the circumference of the reversing body. Moreover, the first guide interface 421, the first shielding structure 424, the second guide interface 422, the second shielding structure 425 and the third guide interface 423 are arranged in sequence along one direction on the circumference of the reversing cylinder 42. Looking in the cross-sectional direction toward the reversing body, when in the first working state, the first opening 4111 and the first guide interface 421 are opposite, the second opening 4112 and the second guide interface 422 are opposite, the third opening 4113 and the third guide interface 423 are staggered, and the second shielding structure 425 is arranged to block the third opening 4113, so that the first opening 4111 and the second opening 4112 are connected through the first guide interface 421 and the second guide interface 422, so that the suction device 3 is connected to the base station 200, and the cleaning equipment 100 enters the sewage discharge state. When the reversing cylinder 42 is driven to rotate, causing the first guide port 421 to rotate to face the portion between the first opening 4111 and the second opening 4112, the third guide port 423 to rotate to face the first opening 4111, the second guide port 422 to rotate to face the third opening 4113, and the first blocking structure 424 to block the second opening 4112, the first opening 4111 and the third opening 4113 are connected through the second guide port 422 and the third guide port 423, that is, the suction device 3 is connected to the sewage collecting chamber 2, and the state switching structure 4 enters the second working state. By rotating the reversing cylinder 42, different guide ports on the reversing cylinder 42 are connected to the corresponding openings on the reversing housing 41 to adjust the working state of the state switching structure 4. The two channels are isolated from each other, which is more convenient for flexible control.

[0199] Preferably, the angle between the first guide opening 421 and the third guide opening 423 is 72°, and the angle between the first guide opening 421 and the second guide opening 422 is 144°. In the radial direction of the reversing cylinder 42, the centerline of the first shielding structure 424 coincides with the bisector of the angle between the first guide opening 421 and the second guide opening 422, and the centerline of the second shielding structure 425 coincides with the bisector of the angle between the second guide opening 422 and the third guide opening 423.

[0200] In another embodiment of the state switching structure 4, as shown in Figures 9 and 10, the first guide port 421 and the third guide port 423 are arranged at intervals along the circumference of the reversing cylinder 42, and the first guide port 421 and the second guide port 422 are arranged at intervals along the axial direction of the reversing cylinder 42; correspondingly, the first opening 4111 and the third opening 4113 are arranged at intervals along the circumference of the reversing body, and the first opening 4111 and the second opening 4112 are arranged at intervals along the axial direction of the reversing body, so that the spacing between the first opening 4111, the second opening 4112 and the third opening 4113 can be larger, and a gap can be formed in the axial direction of the reversing body, so that each opening can be better connected to other structures. Specifically, the second opening 4112 can be more conveniently connected to the base station 200, so that the third opening 4113 can be more conveniently connected to the sewage collection chamber 2, so that there is enough space to arrange the connecting structure, which can better meet the docking requirements of different devices.

[0201] At this time, in the first working state, the first opening 4111 is opposite to the first guide port 421, the second opening 4112 is opposite to the second guide port 422, and the second shielding structure 425 blocks the third opening 4113, forming a first channel between the first guide port 421 and the second guide port 422. Therefore, when the first opening 4111 is connected to the first guide port 421 and the second opening 4112 is connected to the second guide port 422, the suction device 3 can be connected to the base station 200, and the third opening 4113 connected to the sewage collecting chamber 2 is closed by the second shielding structure 425. When the suction device 3 is turned on, a negative pressure can be formed in the base station 200, so that the sewage in the sewage collecting chamber 2 can be sucked out through the base station 200. In the second operating state, the first opening 4111 and the third guide port 423 are opposite each other, the third opening 4113 is opposite the first guide port 421, and the first shielding structure 424 blocks the second guide port 422. The first guide port 421 and the third guide port 423 are connected to form the aforementioned second channel. When the first opening 4111 and the third guide port 423 are connected and connected, and the third opening 4113 and the first guide port 421 are connected and connected, the suction device 3 can be connected to the sewage collection chamber 2, and the third guide port 423, which is connected to the base station 200, is in a closed state under the action of the first shielding structure 424. Therefore, when the suction device 3 is turned on, a negative pressure can be formed in the sewage collection chamber 2, allowing external waste to be sucked into the sewage collection chamber 2. By switching the drive component 43 / 43' to drive the reversing cylinder 42 to rotate, different air ducts are connected to the suction device 3, thereby achieving switching between the first and second operating states. The operation is simple and easy to control.

[0202] 9 , the second shielding structure 425 is formed between the first guide opening 421 and the third guide opening 423, and the first shielding structure 424 and the second guide opening 422 are arranged along the circumference of the reversing cylinder 42. The first shielding structure 424 and the second shielding structure 425 can be part of the circumferential sidewall of the reversing cylinder 42, or alternatively, can be fixed to the outer side of the circumferential sidewall of the reversing cylinder 42.

[0203] Furthermore, as shown in Figure 9, the reversing body can be composed of two parts, the reversing body includes a first shell and a second shell that are detachably connected, the first shell and the second shell are connected and arranged along the axial direction, the first shell and the second shell are both roughly cylindrical, and one end is open, the open end of the first shell and the open end of the second shell are connected to each other, the above-mentioned first opening 4111 and the third opening 4113 are provided on the first shell, and the above-mentioned second opening 4112 is provided on the second shell, so that after the reversing cylinder 42 is installed in the reversing body, the first shell and the second shell can be completely fixed.

[0204] Furthermore, the reversing cylinder 42 is also constructed in two parts, comprising a first and second connected cylinder segments. The first and second cylinder segments form a circumferentially fixed engagement, allowing rotation of one to drive the other. The first and third guide ports 421, 423 are located on the first cylinder segment, while the second guide port 422 is located on the second cylinder segment. The first cylinder segment is rotatably mounted within the first housing, while the second cylinder segment is rotatably mounted within the second housing. This facilitates assembly and allows for individual cylinder segment replacement during maintenance, reducing maintenance costs.

[0205] Preferably, a sealing sheet or a flexible sealing piece may be provided on the side of the first shielding structure 424 and the second shielding structure 425 facing the reversing body, and the sealing sheet or the flexible sealing piece may be used to seal between the opening and the corresponding guide interface, thereby ensuring a more reliable seal and making the suction force generated by the suction device 3 more efficient, thereby improving work efficiency.

[0206] Preferably, as shown in FIG9 , the switching drive component 43 includes a reversing drive 431, a drive worm 432, and a drive worm gear 433. The reversing drive 431 is connected to the drive worm 432, which meshes with the drive worm gear 433, and the drive worm gear 433 is connected to the reversing cylinder 42. The reversing drive 431 may be provided with a reversing drive motor, which drives the drive worm 432 to rotate, thereby driving the drive worm gear 433 to rotate, thereby driving the reversing cylinder 42 to rotate. Specifically, the rotation shaft of the drive worm gear 433 is connected to the bottom of the first cylinder section. The rotation of the drive worm gear 433 drives the first cylinder section to rotate, and the second cylinder section to rotate as well, thereby causing the guide interface on the reversing cylinder 42 to shift to connect with the corresponding opening, thereby achieving switching between the first working state and the second working state. By driving the worm wheel 433 and the worm 432 in coordination with each other, the transmission accuracy is higher and the working noise is lower, so that the working noise of the entire cleaning device 100 is lower.

[0207] In addition, the state switching structure 4 may further include a detection component and a control device 10000. The control device 10000 is electrically connected to the detection component and the switching drive component 43. The detection component is used to detect the position state of the reversing body, and the control device 10000 is used to control the working state of the switching drive component 43 based on the detection result of the detection component. This allows the working state of the state switching structure 4 to be monitored in real time, thereby further ensuring the accuracy of the working state of the cleaning device 100.

[0208] Specifically, the detection component includes a position sensor. Preferably, the position sensor includes a Hall element and a detection block. The detection block is sensed by the Hall element, thereby sending different detection signals to the control device. The control device controls the state switching structure 4 to work according to the detection signal.

[0209] The Hall element can be disposed on the commutation body, corresponding to the second opening 4112 and / or the third opening 4113, and the detection block can be disposed on the commutation cylinder 42, corresponding to the second conductive interface 422 and / or the third conductive interface 423. For example, when the Hall element is located at the second opening 4112 and detects the detection block, it indicates that the second opening 4112 and the second conductive interface 422 are conductively connected. At this point, the Hall element can emit a first detection signal, and the control device can determine that the state switching structure 4 / 4' is in the first operating state based on the first detection signal. Alternatively, a Hall element can also be disposed at the third opening 4113, and a detection block can be disposed at the third conductive interface 423. When the Hall element located at the third opening 4113 detects the detection block located at the third conductive interface 423, a second detection signal can be emitted. Based on the second detection signal, the control device can determine that the state switching structure 4 is in the second operating state, and can then control whether the switching drive component 43 is in operation as required. There are many different configurations and locations for the detection components, which are not described in detail here.

[0210] The arrangement of the reversing housing 41 / 41' and the reversing body is not limited to the above-described arrangement. In another embodiment, as shown in Figures 16 to 19, the second opening 4112' and the third opening 4113' may be arranged at intervals along the circumference of the reversing housing 41'. In this case, the reversing body may include a reversing shaft 44 and a reversing baffle 45 disposed on one side of the reversing shaft 44. The switching drive component 43' is connected to the reversing shaft 44 and is used to drive the reversing shaft 44 to rotate, so that the reversing baffle 45 can rotate along with the reversing shaft 44 as a rotation axis. The reversing baffle 45 can respectively block the second opening 4112' and the third opening 4113', so that the first opening 4111' can communicate with the third opening 4113' and the second opening 4112', respectively, to be in the second working state and the first working state, respectively, resulting in a simpler structure.

[0211] It is understandable that, in one embodiment, the second opening 4112' and the third opening 4113' can be located on both sides of the first opening 4111', respectively. By rotating the reversing body, the reversing body can pass through the second opening 4112', the first opening 4111' and the third opening 4113' in sequence, or the reversing body can pass through the third opening 4113', the first opening 4111' and the second opening 4112' in sequence, so as to realize the switching between the first working state and the second working state. For example, when the cleaning device 100 is in the sewage discharge state, the reversing baffle 45 is at the third opening 4113'. By switching the driving component 43' to drive the reversing shaft 44 to rotate, the reversing baffle 45 can be rotated from the third opening 4113' through the first opening 4111' to the second opening 4112', thereby blocking the second opening 4112', so as to enter the sewage suction state in which the suction device 3 is connected to the sewage collecting chamber 2. The reversing body can sequentially pass through the second opening 4112 ′, the first opening 4111 ′ and the third opening 4113 ′, and can achieve blocking of any opening, which is more flexible and diverse.

[0212] Preferably, in combination with Figures 16 to 19, the second opening 4112' and the third opening 4113' may be located on the same side of the first opening 4111'. By rotating the reversing body, the reversing body can be reciprocated and switched between the second opening 4112' and the third opening 4113'. For example, when the cleaning device 100 is in a cleaning state of sucking dirt, the reversing body is set to block the second opening 4112'. After cleaning is completed, the reversing body can be driven to rotate a first preset angle in a clockwise direction so that the reversing body is rotated to block the third opening 4113', so as to enter a sewage discharge state in which the suction device 3 is connected to the base station 200. The reversing body only switches between the second opening 4112' and the third opening 4113', and does not pass through the first opening 4111'. The rotation path is shorter, and the switching speed is faster.

[0213] Correspondingly, the switching drive component 43' is also configured differently. As shown in Figures 16 and 17 , the switching drive component 43' is disposed outside the reversing housing 41' and connected to one end of the reversing shaft 44. The switching drive component 43' may include a blocking driver 46, which drives the reversing shaft 44 to rotate, thereby achieving automatic movement of the reversing baffle 45.

[0214] Specifically, the reversing baffle 45 has a shielding portion extending along the circumference of the reversing shaft 44. Driven by the shielding driver 46, the shielding portion can respectively shield the second opening 4112' and the third opening 4113'. The shielding portion forms the aforementioned first shielding structure 424 and second shielding structure 425, enabling switching between the first operating state and the second operating state. The shielding portion can be a portion of the reversing baffle 45, or it can be detachably connected to the reversing baffle 45, and the shielding portion is respectively engaged at the second opening 4112' and the third opening 4113' to form a blockage thereon.

[0215] Furthermore, the state switching structure 4' may also include a drive handle, wherein an adjustment groove is provided on one of the drive handle and the reversing shaft 44, and an adjustment protrusion is provided on the other that plugs into the adjustment groove. When the drive handle is rotated by an external force, the adjustment groove and the adjustment protrusion cooperate to drive the reversing shaft 44 to rotate, thereby forming a non-rotating fit between the drive handle and the reversing shaft 44. When the switching drive component 43' fails to operate normally, the drive handle can be manually rotated, thereby driving the reversing shaft 44 and the reversing baffle 45 to rotate together, thereby switching the state switching structure 4' between the first working state and the second working state. The state switching structure 4' can be driven by both manual drive and drive motor drive. When the switching drive component 43' fails to operate normally, the working state can be switched manually, which makes the operation more flexible and thus adaptable to a wider range of situations.

[0216] 17 , the reversing shell 41 ' comprises a cavity body 411 and an extension portion 412. The cavity body 411 is a roughly fan-shaped columnar body with a hollow interior. The extension portion 412 protrudes from one side of the cavity body 411. The first opening 4111 ', the second opening 4112 ' and the third opening 4113 ' are arranged in sequence along the circumference of the cavity body 411. The extension portion 412 extends outward from the circumference of the first opening 4111 ', thereby forming an interface suitable for docking with the suction device 3. The reversing baffle 45 is provided on the inner side of the cavity body 411, and a through hole is provided on the reversing baffle 45 that passes through the circumference of the reversing shell 41 '. When the reversing baffle 45 is in the second working state, the first opening 4111 ' and the third opening 4113 ' can be connected through the through hole to ensure that the suction device 3 is connected to the dirt collecting chamber 2 of the cleaning equipment 100.

[0217] Further, as shown in Figure 19, the cavity body 411 has a first inner wall 4114, a second inner wall 4115, and a transition wall 4116 connecting the first inner wall 4114 and the second inner wall 4115. The first inner wall 4114 and the third inner wall form two side walls of a fan shape respectively. The transition wall 4116 is an arc-shaped fan-shaped wall. The first opening 4111' is provided on the first inner wall 4114, and the second opening 4112' and the third opening 4113' are provided on the transition wall 4116. The shape of the shielding portion is adapted to the shape of the transition wall 4116, that is, the shielding portion is also provided in an arc shape, so as to better block the second opening 4112' and the third opening 4113' provided in an arc shape.

[0218] Furthermore, the cavity body 411 has a bottom wall connected to the first inner wall 4114, the second inner wall 4115, and one end of the transition wall 4116, and also has a top wall that is detachably mounted to the first inner wall 4114, the second inner wall 4115, and the transition wall 4116. The reversing shaft 44 is rotatably mounted on the top wall. A guide cylinder is provided on the cavity body 411. After the reversing shaft 44 is rotatably mounted on the top wall, the top wall cover with the reversing body installed is then mounted on the first inner wall 4114, the second inner wall 4115, and the transition wall 4116, and the reversing shaft 44 is rotatably mounted on the guide cylinder, thereby sealing the cavity body 411. The assembly of the reversing body is not limited to the internal space of the cavity body 411, making assembly more convenient, and subsequent disassembly is also convenient for maintenance, resulting in lower maintenance costs.

[0219] Furthermore, the state switching structure 4 / 4' also includes a limiting structure. This limiting structure limits the rotational direction of the reversing cylinder 42, preventing incorrect rotational direction from causing communication failure. For example, when the reversing cylinder 42 is in the first operating state, rotating it clockwise to switch to the second operating state. In the counterclockwise direction, the limiting structure forms a stop against the reversing cylinder 42, preventing the reversing cylinder 42 from rotating counterclockwise. When the reversing cylinder 42 is in the second operating state, rotating it counterclockwise resets the state switching structure 4' to the first operating state. The limiting structure forms a clockwise stop against the reversing cylinder 42, preventing the reversing cylinder 42 from further clockwise rotation in the first operating state, thereby ensuring the adjustment stability of the reversing cylinder 42. The limiting structure can be configured as a stop protrusion, which engages with the sidewall of the reversing cylinder 42 to form a stop.

[0220] Specifically, for the reversing baffle 45, as shown in Figures 21 and 22, the reversing baffle 45 has a first stop wall 451 and a second stop wall 452 that are arranged in opposite directions along the circumference of the reversing shaft 44. When the reversing body is in the first working state, the second stop wall 452 forms a stop fit with the second inner wall 4115 to prevent the reversing baffle 45 from continuing to rotate along the second opening 4112' toward the third opening 4113', thereby preventing the reversing baffle 45 from rotating too much and failing to completely close the third opening 4113'. At the same time, it can indicate that the reversing baffle 45 has rotated to the position and can stop rotating. When the reversing body is in the second working state, the first stop wall 451 forms a stop fit with the first inner wall 4114 to prevent the reversing baffle 45 from continuing to rotate along the third opening 4113' toward the second opening 4112', thereby preventing the reversing baffle 45 from rotating too much and failing to completely close the second opening 4112'. At the same time, it can indicate that the reversing baffle 45 has rotated to the right position and can stop rotating.

[0221] Furthermore, the end of the reversing baffle 45 facing away from the reversing shaft 44, i.e., the end of the reversing baffle 45 that seals the second opening 4112' and the third opening 4113', is made of an elastic material. This elastic material allows the reversing baffle 45 to more closely contact the second opening 4112' and the third opening 4113', thereby achieving a better sealing effect. Alternatively, a sealing member is bonded to the end of the reversing baffle 45 facing away from the reversing shaft 44. This sealing member can seal the gap between the reversing baffle 45 and the second opening 4112' and the third opening 4113', thereby ensuring a better sealing effect. The sealing member can be a sealing gasket or a sealing ring, and can be made of an elastic material such as rubber or sponge.

[0222] A Hall element may be provided on the first inner wall 4114 and / or the second inner wall 4115, and a detection block may be provided on the first stop wall 451 and / or the second stop wall 452. When the first stop wall 451 is rotated into position, the Hall element on the first inner wall 4114 detects the detection on the first stop wall 451, thereby sending a second detection signal to the control device, indicating that the state switching structure 4' is in the second operating state. When the second stop wall 452 is rotated into position, the Hall element on the second inner wall 4115 detects the detection on the second stop wall 452, thereby sending a first detection signal to the control device, indicating that the state switching structure 4' is in the first operating state. Alternatively, the Hall elements may be provided corresponding to the second opening 4112' and / or the third opening 4113', and the detection block may be provided on the reversing baffle 45. Similarly, the Hall elements may emit different detection signals to indicate that the state switching structure 4' is in different operating states. Then, the control device controls the switching drive component 43' to work according to different detection signals, so that the switching drive component 43' can be stopped in time after the reversing baffle 45 rotates to the right position and continues to work, which is more energy-saving and more intelligent.

[0223] In addition, as shown in Figures 16 to 18, an air duct docking structure 5 is further provided in the cleaning device 100, through which the second opening 4112' and the base station 200 can be connected. Specifically, the air duct docking structure 5 is provided with a first air guide port 51 connected to the second opening 4112', and a second air guide port 52 connected to the first air guide port 51. The second air guide port 52 can be provided on the outside of the cleaning device 100. When the cleaning device 100 is docked with the base station 200, the second air guide port 52 can be connected to the sewage discharge channel on the base station 200.

[0224] In one embodiment, when the cleaning device 100 is also provided with a clean water tank, a guide port 53 may be further provided on the air duct docking structure 5, the guide port 53 being connected to the clean water tank, and preferably, the guide port 53 is located on the same side as the second air guide port 52. When the cleaning device 100 is docked with the base station 200, the guide port 53 may be connected to a water supply device on the base station 200 (such as a base station clean water tank or a tap water pipe docking joint), so that the clean water tank on the cleaning device 100 can be automatically supplied with water through the base station 200. The air duct docking structure 5 makes the structure of the air duct and water supply channel in the entire cleaning device 100 more compact and the layout more optimized, thereby taking up less space.

[0225] Furthermore, the base station 200 can be provided with only a storage chamber for waste, eliminating the need for a base station fresh water tank, resulting in a simpler structure. When water is needed, fresh water is directly supplied to the fresh water tank of the cleaning equipment from the tap water pipe through a three-way valve, resulting in a simpler structure and a lighter base station 200.

[0226] The present disclosure also provides a control device of a cleaning system 1000. It should be noted that, referring to Figure 24, the control device 10000 of the cleaning system 1000 may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein, the communication bus 1002 is used to realize the connection communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and a button. The optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0227] Those skilled in the art will understand that the structure of the control device 10000 shown in FIG24 does not constitute a limitation on the control device 10000 , and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0228] As shown in FIG. 24 , the memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a control program of the cleaning system 1000 .

[0229] In the control device 10000 shown in FIG24 , the processor 1001 calls the control program of the cleaning system 1000 stored in the memory 1005 and performs the following operations:

[0230] In response to the sewage discharge signal, the suction device 3 is controlled to communicate with the base station 200;

[0231] When the base station 200 and the cleaning device 100 are in a sewage discharge state in which they are connected, the suction device 3 is controlled to act on the base station 200 to suck the sewage from the cleaning device 100 into the base station 200 .

[0232] Furthermore, when the cleaning system 1000 further includes a state switching structure 4 / 4', and the state switching structure 4 / 4' has a first working state of connecting the base station 200 and the suction device 3, the processor 1001 calls the control program of the cleaning system 1000 stored in the memory 1005, and further performs the following operations:

[0233] In response to the sewage discharge signal, the state switching structure 4 / 4 ′ is controlled to switch to the first working state, so that the suction device 3 is connected to the base station 200 through the state switching structure 4 / 4 ′.

[0234] Furthermore, when the base station 200 includes a storage chamber and the cleaning device 100 includes a dirt collecting chamber 2, the processor 1001 calls the control program of the cleaning system 1000 stored in the memory 1005 and further performs the following operations:

[0235] When the base station 200 and the cleaning device 100 are in a relative sewage discharge state, the storage chamber is connected to the sewage collecting chamber 2, and the suction device 3 is controlled to act on the base station 200, so that the sewage in the sewage collecting chamber 2 is sucked into the storage chamber.

[0236] In combination with the above hardware facilities, the present disclosure further provides a control method for a cleaning system 1000. As shown in FIG23 , the control method for the cleaning system 1000 includes the following steps:

[0237] S100, in response to the sewage discharge signal, controlling the suction device 3 to communicate with the base station 200;

[0238] Specifically, in response to the sewage discharge signal, it refers to the sewage discharge signal corresponding to the sewage discharge instruction issued by the user, or the sewage discharge signal triggered by the cleaning system 1000 when it is in a certain state. For example, a sewage discharge button may be provided on the cleaning device 100 or the base station 200, and the user issues a sewage discharge instruction by triggering the sewage discharge button. Among them, the sewage discharge button can be set to a button type, a touch type, or a remote control type to realize a trigger switch in multiple modes. Alternatively, when the cleaning device 100 is placed on the base station 200, the sewage discharge instruction can be triggered and the sewage discharge signal can be issued through the contact and docking of the cleaning device 100 and the base station 200, so that the cleaning system 1000 can automatically enter the sewage discharge state, thereby controlling the suction device 3 to be connected to the base station 200. Of course, there are many ways to form a sewage discharge signal, which can be reasonably set according to usage habits or the specific structure of the cleaning device 100.

[0239] S200 , when the base station 200 and the cleaning device 100 are in a connected sewage discharge state, control the suction device 3 to act on the base station 200 to suck the sewage from the cleaning device 100 to the base station 200 .

[0240] After the base station 200 is docked with the cleaning device 100, the suction device 3 can be controlled to start working, so that a negative pressure can be formed in the base station 200 under the action of the suction device 3, and then the dirt in the cleaning device 100 is sucked out by the negative pressure in the base station 200, thereby cleaning the cleaning device 100.

[0241] It can be understood that when the base station 200 and the cleaning equipment 100 are in the sewage discharge state, it means that there is a communication path between the base station 200 and the cleaning equipment 100, and the communication path is in a conductive state, so that when the suction device 3 is turned on, the suction force formed by the suction device 3 can enter the base station 200, so that negative pressure is formed in the base station 200 to suck out the dirt at the cleaning equipment 100.

[0242] The control method of the cleaning system 1000 provided in the present disclosure enables the cleaning system 1000 to connect the suction device 3 with the base station 200 after receiving the sewage discharge signal, and to act on the base station 200 through the suction device 3 on the cleaning device 100, so that the dirt in the cleaning device 100 can be sucked out by the base station 200, that is, the treatment of the dirt in the cleaning device 100 can be provided by the suction device 3 of its own to provide suction power, and there is no need to set up an additional suction device 3 for sewage discharge on the base station 200, so that the structure of the base station 200 can be simpler, the cost is lower, and it is more conducive to the optimization of the structure of the base station 200.

[0243] It is understood that there are numerous ways to control the communication between the suction device 3 and the base station 200. In one embodiment, when a communication duct, such as an external connecting pipe, is provided between the suction device 3 and the base station 200, the communication between the suction device 3 and the base station 200 can be controlled by controlling the opening of the connecting pipe. For example, a valve structure can be provided within the connecting pipe, and the opening of the valve structure can be controlled to control the opening of the connecting pipe.

[0244] Preferably, the cleaning system 1000 includes a state switching structure 4 / 4', and when the state switching structure 4 / 4' is in the first working state of connecting the base station 200 and the suction device 3, the above step S100 specifically includes:

[0245] S110 , in response to the sewage discharge signal, controlling the state switching structure 4 / 4 ′ to switch to the first working state, so that the suction device 3 is connected to the base station 200 through the state switching structure 4 / 4 ′.

[0246] After receiving the sewage discharge signal, the state switching structure 4 / 4' is controlled to move so that the state switching structure 4 / 4' is in the first working state. Then, the suction device 3 and the base station 200 can be connected through the state switching structure 4 / 4', so that the suction device 3 can act on the base station 200, thereby cleaning the dirt of the cleaning equipment 100.

[0247] Moreover, in one embodiment, the cleaning device 100 may further include a dirt collecting chamber 2, and the state switching structure 4 / 4' may further have a second working state in which the suction device 3 and the dirt collecting chamber 2 are connected. When the cleaning device 100 is performing cleaning work normally, the suction device 3 and the dirt collecting chamber 2 can be connected through the state switching structure 4 / 4', so that under the action of the suction device 3, a negative pressure is formed in the dirt collecting chamber 2 of the cleaning device 100, and external dirt can enter the interior of the cleaning device 100 from the dirt suction port of the cleaning device 100 and flow into the dirt collecting chamber 2, and the dirt is stored in the dirt collecting chamber 2. After the cleaning device 100 is finished cleaning, the cleaning device 100 can be connected to the base station 200, and a sewage discharge signal is sent, so that the state switching structure 4 / 4' can be switched to the first working state to remove the dirt in the dirt collecting chamber 2 through the base station 200. The suction device 3 of the cleaning device 100 can provide power for the suction of external dirt, and can also provide power for the base station 200 to clean the dirt collecting chamber 2, so the functions are more diverse.

[0248] Furthermore, the cleaning system 1000 further includes a detection component for detecting the working state of the state switching structure 4 / 4'; the above step S110 specifically includes:

[0249] After receiving the sewage discharge signal, the detection information of the detection component is obtained, and it is determined whether the state switching structure 4 / 4' needs to be moved according to the detection information;

[0250] If the detection component detects that the state switching structure 4 / 4' is not in the first working state, the state switching structure 4 / 4' is controlled to move so that the state switching structure 4 / 4' is in the first working state;

[0251] If the detection component detects that the state switching structure 4 / 4' is in the first working state, the state switching structure 4 / 4' is controlled to remain stationary.

[0252] Specifically, the detection component can be configured as a position sensor, and the state switching structure 4 / 4' can include a reversing housing 41 / 41' and a reversing body that can move relative to the reversing housing 41 / 41'. The position of the reversing body can be detected by the position sensor. For example, the position sensor can be configured as a Hall switch, by providing a Hall element at the first position of the reversing housing 41 / 41' and providing a detection block on the reversing body. When the detection block is within the detection area of ​​the Hall element, the Hall element can send a first detection signal to the control device, indicating that the state switching structure 4 / 4' is in the first working state; when the detection block is outside the detection range of the Hall element, the Hall element can send a second detection signal to the control device, indicating that the state switching structure 4 / 4' enters the second working state. There are many ways to set up the detection component, and there are also many corresponding detection methods, but the detection principles are generally the same. They are not listed here one by one for description. The above-mentioned cleaning system 1000 can be referred to for implementation.

[0253] Furthermore, when cleaning system 1000 includes a switching drive component 43 / 43', position information detected by the detection component is fed back to the control device, which then controls the operation of the switching drive component 43 / 43' to adjust the operating state of the state switching structure 4 / 4'. The detection component allows for better monitoring of the operating state of the state switching structure 4 / 4', thereby enabling better control of the operation of the state switching structure 4 / 4', making the operation of the entire cleaning system 1000 more intelligent.

[0254] When the cleaning device 100 is provided with a dirt collecting chamber 2, the base station 200 may include a storage chamber, which can store the dirt sucked out from the dirt collecting chamber 2. In this case, the above step S200 specifically includes:

[0255] S210: When the base station 200 and the cleaning device 100 are in a relative sewage discharge state, the storage chamber is connected to the sewage collecting chamber 2, and the suction device 3 is controlled to act on the base station 200, so that the sewage in the sewage collecting chamber 2 is sucked into the storage chamber.

[0256] When the base station 200 is connected to the cleaning equipment 100, the suction device 3 can be connected to the storage chamber, and the storage chamber can be connected to the dirt collecting chamber 2. When the suction device 3 is turned on, the suction airflow can flow from the dirt collecting chamber 2 to the storage chamber of the base station 200, and then the clean airflow can flow to the suction device 3 for discharge. The dirt enters the storage chamber for storage, and the clean airflow can flow to the suction device 3.

[0257] The storage chamber can be configured as a storage box or a storage bag to accommodate the waste in the waste collecting chamber 2. Furthermore, in conjunction with the previous embodiment, when the base station 200 is connected to the cleaning device 100, the state switching structure 4 / 4' can connect the suction device 3 to the storage chamber, thereby forming a negative pressure in the storage chamber and sucking out the waste in the waste collecting chamber 2.

[0258] In another embodiment, the base station 200 may further include a cleaning tank, which can be used to clean the cleaning components of the cleaning device 100. Dirt generated during the cleaning process will be retained in the cleaning tank. The cleaning tank can be connected to a storage chamber. When the cleaning device 100 and the base station 200 are connected, and the state switching structure 4 / 4' connects the suction device 3 and the storage chamber, a negative pressure is generated in the storage chamber, thereby sucking out the dirt in the cleaning tank, thereby cleaning the cleaning tank.

[0259] Alternatively, there is no need to set up a storage chamber on the base station 200. A sewage discharge channel is formed on the base station 200, and the sewage discharge channel can be connected to a sewage treatment site (such as a sewer). After the cleaning device 100 is connected to the base station 200, when it is in the first working state, the suction device 3 on the cleaning device 100 is connected to the sewage discharge channel, so that a negative pressure can be formed in the sewage discharge channel. The dirt in the cleaning device 100 can be directly sucked into the sewer without the need to clean the base station 200. The operation is more convenient and less worrying.

[0260] The present disclosure provides a cleaning system 1000. As shown in Figures 1, 2 and 11, the cleaning system 1000 includes a cleaning device 100 and a base station 200. The cleaning device 100 includes an equipment body 1 and a suction device 3 provided on the equipment body 1. When the base station 200 and the cleaning device 100 are docked, a first air duct may be connected between the suction device 3 and the base station 200, and the suction airflow of the suction device 3 enters the base station 200 through the first air duct.

[0261] In this embodiment, when the cleaning device 100 is connected to the base station 200, a first air duct may be provided between the suction device 3 and the base station 200. The suction device 3 allows the suction airflow of the suction device 3 to enter the base station 200 through the first air duct, so that a negative pressure is formed in the base station 200. The base station 200 can then be connected to the dirt collecting chamber 2 of the cleaning device 100 or the cleaning tank of the base station 200 itself, so that the dirt in the dirt collecting chamber 2 or the cleaning tank can be sucked into the base station 200, thereby achieving automatic cleaning. The setting method of the cleaning system 1000 makes it unnecessary to set up a power device to provide power for dirt removal on the base station 200, and fully utilizes the suction device 3 on the cleaning device 100. Obviously, the cost is lower, and the assembly and maintenance are more convenient with fewer parts, which can effectively reduce the cost of the entire cleaning system 1000 and enhance the user experience.

[0262] In this embodiment, when the suction device 3 is connected to the base station 200, the base station 200 can be located between the suction side of the suction device 3 and the sewage collecting chamber 2 along the path of the suction airflow. The base station 200 is located upstream of the suction side of the suction device 3, and the sewage collecting chamber 2 is located upstream of the base station 200. The suction device 3 is used to form a negative pressure in the base station 200, and the sewage in the sewage collecting chamber 2 enters the base station 200 under the action of the suction airflow.

[0263] In one embodiment, the first air duct can be configured as a connecting pipe to connect the suction device 3 and the base station 200; or, the first air duct includes a first air duct section and a second air duct section, the first air duct section is formed on the base station 200 to form an airflow channel, the second air duct section is formed on the cleaning device 100, and a docking port is provided on the cleaning device 100, and the suction device 3 and the docking port are connected through the second air duct section. When the cleaning device 100 is placed on the base station 200, the docking port is connected to the airflow channel of the base station 200, and then the suction device 3 and the base station 200 are connected through the first air duct section, the docking port and the second air duct section.

[0264] It can be understood that the cleaning device 100 also has a cleaning state in which cleaning work can be performed normally. For example, the cleaning device 100 can be used to clean dirt on the ground, walls or glass. Specifically, the cleaning device 100 also includes a dirt collecting chamber 2, which is connected to the dirt suction port of the cleaning device 100; a second air duct may be connected between the suction device 3 and the dirt collecting chamber 2, and the suction airflow of the suction device 3 enters the dirt collecting chamber 2 through the second air duct. Under the action of the negative pressure in the dirt collecting chamber 2, external dirt can be sucked into the cleaning device 100 through the dirt suction port and flow toward the dirt collecting chamber 2. The dirt is stored in the dirt collecting chamber 2, and the cleaning device 100 performs cleaning work in this way.

[0265] The suction device 3 may include a fan and a fan housing. The fan may be configured as an axial flow fan or a centrifugal fan. The fan housing has a receiving chamber, and the fan is disposed within the receiving chamber. The fan housing is in communication with the device body 1. The fan housing has an air inlet connected to the air inlet end of the fan and an air outlet connected to the air outlet end of the fan. When the suction device 3 is connected to the base station 200, the air inlet on the fan housing is connected to the base station 200 and the sewage collecting chamber 2, so as to facilitate the fixing of the fan and facilitate the establishment of electrical connection between the base station 200 and the sewage collecting chamber 2.

[0266] Preferably, as shown in Figures 2, 5, 12, and 14, the cleaning system 1000 further includes a state switching structure 4 / 4', which has a first operating state in which the first air duct is open and the second air duct is blocked. After the cleaning device 100 is connected to the base station 200, the state switching structure 4 / 4' opens the first air duct and blocks the second air duct to enter the first operating state, thereby connecting the suction device 3 and the base station 200. The suction force generated by the suction device 3 can enter the base station 200 through the state switching structure 4 / 4', creating a negative pressure inside the base station 200.

[0267] Specifically, the base station 200 may include a storage chamber, or the base station 200 may have at least a sewage discharge channel for sewage discharge, through which the sewage in the sewage collecting chamber 2 of the cleaning device 100 can be conducted to the storage chamber or directly to a sewage treatment site (such as a sewer). When the base station 200 is docked with the cleaning device 100, a first air duct is connected between the suction device 3 and the storage chamber or sewage discharge channel, and the suction airflow enters the storage chamber or sewage discharge channel through the first air duct, thereby connecting the base station 200 and the suction device 3. The suction device 3 forms a negative pressure in the storage chamber or sewage discharge channel of the base station 200, and the sewage in the sewage collecting chamber 2 of the cleaning device 100 can enter the sewage discharge channel under the action of the suction force, and then enter the storage chamber or sewer. Among them, the storage chamber of the base station can store 1.5 liters to 2 liters of water. The large water storage capacity prevents the sewage in the storage chamber from being blocked when it is discharged to the sewer.

[0268] Among them, the storage chamber and the sewage collecting chamber 2 are connected through the first sewage outlet on the base station 200 and the second sewage outlet on the cleaning equipment 100. The second sewage outlet is connected to the sewage collecting chamber 2. The second sewage outlet can be set on the outer surface of the cleaning equipment 100, and a cover is provided at the second sewage outlet. When the cleaning equipment 100 is in a non-sewage discharge state, the cover is pressed at the second sewage outlet by a torsion spring to prevent the sewage in the sewage collecting chamber 2 from overflowing. When the cleaning equipment 100 is docked with the base station 200 for sewage discharge, the cover can be sucked open under the action of the suction force of the suction device 3, so that the sewage in the sewage collecting chamber 2 can enter the first sewage outlet from the second sewage outlet and enter the storage chamber.

[0269] Alternatively, a cleaning tank may be provided on the base station 200, which can be used to clean the cleaning parts (such as roller brushes, rags, etc.) on the cleaning device 100. The sewage, debris, and other dirt generated during the cleaning process will remain in the cleaning tank. The cleaning tank is connected to the sewage discharge channel. When the cleaning device 100 is placed on the base station 200 and the sewage collecting chamber 2 is cleaned, the cleaning parts can be cleaned at the same time, so that the dirt in the sewage collecting chamber 2 and the dirt in the cleaning tank can be sucked into the sewage discharge channel. There is no need to set up an additional device to provide suction power on the base station 200. While the functions of the base station 200 can be more diversified, the structure of the base station 200 is simpler, the cost is lower, and it is more convenient to use.

[0270] Furthermore, as shown in Figures 5 to 7 , the state switching structure 4 / 4' further has a second operating state in which the second air duct is open and the first air duct is blocked. By connecting the second air duct through the state switching structure 4 / 4', the suction device 3 and the dirt collecting chamber 2 are connected, so that the dirt collecting chamber 2 can form a negative pressure under the action of the suction device 3, thereby sucking in external dirt. Furthermore, blocking the first air duct prevents some airflow from entering the base station 200, increasing the suction force within the dirt collecting chamber 2 and thus improving the cleaning effect.

[0271] It can be understood that the state switching structure 4 / 4' can be set on the cleaning device 100, or can be set on the base station 200, or the state switching structure 4 / 4' can be an independent structure to be set independently of the cleaning device 100 and the base station 200, or the state switching structure 4 / 4' can be provided with multiple sets, which are respectively located on the cleaning device 100 and the base station 200, so as to ensure that the suction device 3 and the base station 200 can be connected through the state switching structure 4 / 4'.

[0272] Preferably, again in conjunction with Figures 2, 5, 12, and 14, the state switching structure 4 / 4' is disposed on the cleaning device 100, and the state switching structure 4 / 4' is disposed closer to the suction device 3. The suction force generated by the suction device 3 can better enter the state switching structure 4 / 4', resulting in less power loss, greater suction force provided, and greater suction force generated within the base station 200, thereby improving the sewage discharge effect. The following will use the state switching structure 4 / 4' disposed on the cleaning device 100 as an example to specifically describe the specific structure of the cleaning system 1000. Other embodiments can be implemented with reference to the adaptability and will not be described one by one here.

[0273] Of course, the state switching structure 4 / 4' may also have other states, such as a waiting state or an initial state, so as to be in a transition or preparation position for entering the first working state or the second working state. Among them, when the state switching structure 4 / 4' is in the first working state, the first air duct is connected to connect the suction device 3 and the base station 200. When the state switching structure 4 / 4' is not in the first working state, and the state switching structure 4 / 4' is in the second working state or other states, the suction device 3 and the base station 200 may be in a blocked state. When the cleaning device 100 is not performing sewage treatment, the communication path between the suction device 3 and the base station 200 is blocked. On the one hand, it can prevent the sewage from flowing out of the sewage collecting chamber 2 of the cleaning device 100 when sewage is not discharged, causing blockage or secondary pollution of the pipeline. On the other hand, it can prevent part of the airflow from entering the base station 200 when the cleaning device 100 is performing cleaning work, causing the airflow to be diverted, affecting the cleaning effect of the cleaning device 100.

[0274] In a normal household cleaning environment, preferably, the state switching structure 4 / 4' can be used to make the cleaning device 100 work in only one of the working states. Among them, when the state switching structure 4 / 4' is in the first working state, the state switching structure 4 / 4' conducts the first air duct and blocks the second air duct; when the state switching structure 4 / 4' is in the second working state, the state switching structure 4 / 4' conducts the second air duct and blocks the first air duct. The state switching structure 4 / 4' can simultaneously achieve the conduction of one of the air ducts and the blocking of the other air duct, making the conduction and blocking operations simpler, and such a setting method prevents the two working states of the cleaning device 100 from appearing at the same time, which can better protect the cleaning device 100. The suction device 3 can selectively connect the base station 200 and the dirt collecting chamber 2, so that the suction force is more concentrated, so the cleaning effect and self-cleaning effect of the cleaning device 100 will be better. Moreover, in a normal household cleaning environment, the power requirement of the suction device 3 is lower than that in a specific environment, so the cost of the suction device 3 is lower, and the structure of the entire cleaning device 100 can be simpler and the cost is also lower.

[0275] At this time, preferably, in combination with Figures 2 to 4, the state switching structure 4 / 4' includes a first opening structure, a second opening structure, a first shielding structure 424 and a second shielding structure 425. In the first working state, the first opening structure connects to the first air duct, and the second shielding structure 425 blocks the second air duct; in the second working state, the second opening structure connects to the second air duct, and the first shielding structure 424 blocks the first air duct to ensure that the suction device 3 is connected to either the first air duct or the second air duct to ensure better sewage discharge effect or cleaning effect.

[0276] Further, in combination with Figures 3 and 13, the first opening structure includes a first opening 4111 / 4111' and a second opening 4112 / 4112', the second opening structure includes a third opening 4113 / 4113' and a fourth docking interface, the first opening 4111 / 4111' is suitable for communicating with the suction device 3, the second opening 4112 / 4112' is suitable for communicating with the base station 200, the third opening 4113 / 4113' is suitable for communicating with the sewage collecting chamber 2, and the fourth docking interface is suitable for communicating with the suction device 3. When in the first working state, the first opening 4111 / 4111' is connected to the second opening 4112 / 4112', so that the first air duct is in a conducting state, and the second shielding structure 425 is arranged to block the third opening 4113 / 4113' to block the second air duct, thereby connecting the suction device 3 and the base station 200. Under the action of the suction device 3, the suction airflow can enter the base station 200, the flow path of the airflow is simpler, the wind resistance is smaller, and the efficiency is higher. When in the second working state, the third opening 4113 / 4113' and the fourth docking interface are connected to conduct the second air duct, and the first shielding structure 424 is set to block the second opening 4112 / 4112' to block the first air duct, so that the suction device 3 and the sewage collecting chamber 2 are connected, and a blockage is formed between the base station 200 and the suction device 3. The suction airflow can enter the sewage collecting chamber 2 through the sewage suction port of the cleaning equipment 100, and the clean airflow after filtration can enter the suction device 3, thereby realizing the cleaning work of the cleaning equipment 100.

[0277] It is understood that the method for achieving blocking and opening of the first and second air ducts is not limited to the above-described method. In another embodiment, the state switching structure 4 / 4' may include at least one first barrier and at least one second barrier, with the at least one first barrier positioned on the first air duct and the at least one second barrier positioned on the second air duct. Each first barrier and each second barrier may be movable, each possessing an open state for opening the air duct and a closed state for blocking the air duct. When each first barrier is in the open state, the first air duct is open; when each first barrier is in the closed state, the first air duct is blocked. By controlling the state of each first barrier, the opening and closing of the communication path between the base station 200 and the suction device 3 are controlled. A single first barrier may be provided for convenient control and simple operation. Alternatively, multiple first barriers may be provided, forming multiple blocks on the communication path between the base station 200 and the suction device 3, resulting in a more effective seal. The first barrier member may be configured as a movable barrier plate, a mechanical valve, a solenoid valve, etc. The first barrier member may be manually moved or driven by a driver.

[0278] Similarly, when each second barrier is in the open state, the second air duct is in the conductive state, and when each second barrier is in the closed state, the second air duct is in the blocked state. By controlling the state of each second barrier to control the conduction and blocking of the communication path between the sewage collecting chamber 2 and the suction device 3, one second barrier can be provided, which is convenient to control and simple to operate. Alternatively, a plurality of second barrier members can be provided, and the plurality of second barrier members form multiple blockages on the communication path between the sewage collecting chamber 2 and the suction device 3, which has a better sealing effect. Among them, the second barrier can be set as a movable barrier plate, a mechanical valve or a solenoid valve. The movement of the second barrier can be manually moved or driven by a driver.

[0279] Optionally, the first barrier member and the second barrier member may be the same.

[0280] Optionally, the first barrier on the first air duct between the base station 200 and the suction device 3 and the second barrier on the second air duct between the sewage collecting chamber 2 and the suction device 3 can block one of the two paths through an external driving device, thereby making the other path conductive.

[0281] In certain circumstances, when one of the first and second air ducts is in a conductive state, the other can also be in a conductive state, that is, the suction device 3 is conductive to the base station 200 and the sewage collection chamber 2. Specifically, if the suction force of the suction device 3 is large enough, and the suction force formed in the first air duct is equal to the suction force formed in the second air duct, the cleaning device 100 can be in two working states at the same time. This allows the sewage collection chamber 2 to form a suction force to suck in external dirt, while the base station 200 can also form a suction force to suck out dirt from the sewage collection chamber 2. The cleaning device 100 can simultaneously suck in dirt and discharge it.

[0282] Specifically, when there is a lot of external dirt and it is heavy, if the cleaning work is performed by the cleaning device 100, since the volume of the cleaning device 100 is relatively small, the volume of the dirt collecting chamber 2 is also relatively small. If the normal cleaning method is used, the dirt collecting chamber 2 of the cleaning device 100 is easy to fill up. When in use, the cleaning device 100 needs to be placed on the base station 200 for self-cleaning many times, and each time the cleaning device 100 performs self-cleaning, it is necessary to wait for a certain period of time, which makes the operation time-consuming and labor-intensive. Therefore, by connecting the cleaning device 100 to the base station 200, and making the suction device 3 connected to the base station 200 and the dirt collecting chamber 2, the dirt sucked into the dirt collecting chamber 2 by the cleaning device 100 can be sucked out in time through the base station 200, without the need to frequently move the cleaning device 100, and without waiting for the cleaning device 100 to perform self-cleaning. Obviously, the operation is more time-saving and labor-saving. Preferably, the air outlet connecting the sewage collecting chamber 2 and the suction device 3 and the sewage outlet connecting the sewage collecting chamber 2 and the base station 200 can be set on the same side of the sewage collecting chamber 2. Therefore, the airflow entering the sewage collecting chamber 2 can flow in the same direction. A filter component can be provided at the air outlet, and the airflow can be filtered by the filter component so that the clean airflow can be discharged through the air outlet to enter the suction device 3, while the dirt can be discharged through the sewage outlet to enter the base station 200, thereby achieving sewage suction and discharge at the same time.

[0283] In this case, the base station 200 can be configured to be movable so that it can be moved along with the cleaning device 100, thereby extending the cleaning range. Alternatively, a longer telescopic connecting pipe can be provided between the base station 200 and the cleaning device 100 to better connect the base station 200 and the cleaning device 100, making it easier to clean when the amount of dirt is large. However, this configuration requires strict control of the suction air flow generated by the suction device 3 to ensure a more balanced air flow entering the base station 200 and the dirt collection chamber 2, thereby achieving a working state of simultaneously sucking and discharging dirt.

[0284] Obviously, the embodiments described above are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, ordinary technicians in this field can make other different forms of changes or modifications without making any creative work, which should fall within the scope of protection of the present disclosure.
