Technical Field

[0004] The cleaning system usually includes a cleaning device and a base station. The cleaning parts and the dirt collecting chamber of the cleaning device can be cleaned through the base station to ensure that the cleaning device is cleaner and has a better cleaning effect when it is used again. Specifically, when the base station is performing self-cleaning of the cleaning device, the dirt removal channel on the base station is connected to the sewage discharge channel on the cleaning device, and the fan on the base station is turned on to form a negative pressure in the dirt removal channel, thereby sucking out the dirty liquid in the sewage collecting chamber of the cleaning device to clean the sewage collecting chamber of the cleaning device.

DETAILED DESCRIPTION

[0074] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0075] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0076] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0077] The utility model provides a cleaning system 1000, combined with Figure 1 , Figure 2 and Fig.11 As shown, the cleaning system 1000 includes a cleaning device 100 and a base station 200, wherein the cleaning device 100 includes an equipment body 1, and a suction device 3 arranged on the equipment body 1; wherein, when the base station 200 and the cleaning device 100 are docked, a first air duct connected between the suction device 3 and the base station 200 may be provided, and the suction airflow of the suction device 3 enters the base station 200 through the first air duct.

[0078] In this embodiment, when the cleaning device 100 is connected to the base station 200, there may be a first air duct connected between the suction device 3 and the base station 200, and 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; and then the base station 200 can 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, and automatic cleaning is achieved. The setting method of the cleaning system 1000 makes it unnecessary to set 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, which is obviously lower in cost, and has fewer parts, and is more convenient to assemble and maintain, which can effectively reduce the cost of the entire cleaning system 1000 and improve the user experience.

[0079] 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 dirt 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 dirt 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 then the dirt in the dirt collecting chamber 2 enters the base station 200 under the action of the suction airflow.

[0080] The cleaning device 100 is preferably configured as a floor scrubber, a sweeper, a vacuum cleaner, or the like.

[0081] In one embodiment, the first air duct may be configured as a connecting pipe fitting 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, 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.

[0082] 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 to flow into the dirt collecting chamber 2, and the dirt is stored through the dirt collecting chamber 2. The cleaning device 100 achieves cleaning work in this way.

[0083] The suction device 3 may include a fan and a fan housing. The fan may be an axial flow fan or a centrifugal fan. The fan housing has a receiving cavity. The fan is arranged in the receiving cavity. The fan housing is connected to 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 that the fan can be fixed and the base station 200 and the sewage collecting chamber 2 can be connected more easily.

[0084] Preferably, combined Figure 2 , Figure 5 , Fig.12 and Fig.14 As shown, the cleaning system 1000 further includes an air duct switching structure 4 / 4', which has a first working state in which the first air duct is in conduction and the second air duct is in blockage. After the cleaning device 100 is connected to the base station 200, the first air duct is conducted and the second air duct is blocked through the air duct switching structure 4 / 4' to enter the first working state, thereby conducting the suction device 3 and the base station 200, and the suction force formed by the suction device 3 can enter the base station 200 through the air duct switching structure 4 / 4', so that negative pressure is formed in the base station 200.

[0085] Specifically, the base station 200 may include a storage chamber, or the base station 200 at least has a sewage discharge channel for sewage discharge, through which the sewage in the sewage collection chamber 2 of the cleaning device 100 can be conducted to be transferred to the storage chamber or directly transferred to the sewage treatment site (such as the sewer). When the base station 200 is docked with the cleaning device 100, there is a first air duct connected between the suction device 3 and the storage chamber or the sewage discharge channel, and the suction airflow enters the storage chamber or the sewage discharge channel through the first air duct, thereby connecting the base station 200 and the suction device 3, and the suction device 3 forms a negative pressure in the storage chamber or the sewage discharge channel of the base station 200, and the sewage in the sewage collection chamber 2 of the cleaning device 100 can enter the sewage discharge channel under the action of the suction force, so as to enter the storage chamber or the 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 can prevent the sewage in the storage chamber from being blocked when it is discharged to the sewer.

[0086] 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 device 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 device 100, and a cover plate is set at the second sewage outlet. When the cleaning device 100 is in a non-discharge state, the cover plate 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 device 100 is connected to the base station 200 for sewage discharge, the cover plate 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.

[0087] Alternatively, a cleaning tank may be provided on the base station 200, and the cleaning tank may be used to clean the cleaning parts (such as roller brushes, rags, etc.) on the cleaning device 100, and the sewage, debris, and other dirt generated during the cleaning process will be retained in the cleaning tank. The cleaning tank is connected to the sewage discharge channel, and when the cleaning device 100 is placed on the base station 200 and the sewage collection chamber 2 is cleaned, the cleaning parts can be cleaned at the same time, so that the dirt in the sewage collection 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, and the functions of the base station 200 can be more diversified. At the same time, the structure of the base station 200 is simpler, the cost is lower, and it is more convenient to use.

[0088] Moreover, combined with Figures 5 to 7 As shown, the air duct switching structure 4 / 4' also has a second working state in which the second air duct is in conduction and the first air duct is in blockage. The second air duct is conducted through the air duct switching structure 4 / 4', and then the suction device 3 and the dirt collecting chamber 2 are conducted, so that the dirt collecting chamber 2 can form a negative pressure under the action of the suction device 3 to absorb external dirt. In addition, blocking the first air duct can prevent part of the airflow from entering the base station 200, so that the suction force in the dirt collecting chamber 2 is greater, thereby achieving a better cleaning effect.

[0089] It can be understood that the air duct switching structure 4 / 4' can be arranged on the cleaning device 100, or can be arranged on the base station 200, or the air duct switching structure 4 / 4' can be an independent structure to be independently arranged from 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 air duct switching structure 4 / 4'.

[0090] Preferably, again combined Figure 2 , Figure 5 , Fig.12 and Fig.14 As shown, the air duct switching structure 4 / 4' is arranged on the cleaning device 100, and the air duct switching structure 4 / 4' is arranged closer to the suction device 3. The suction force generated by the suction device 3 can better enter the air duct switching structure 4 / 4', so that the power loss is smaller, the suction force provided is greater, and the suction force formed in the base station 200 is also greater, so that the sewage discharge effect is better. The following will take the air duct switching structure 4 / 4' arranged on the cleaning device 100 as an example to specifically describe the specific structure of the cleaning system 1000. Other implementations can refer to the adaptive implementation, and will not be described one by one here.

[0091] Of course, the air duct 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 air duct switching structure 4 / 4' is in the first working state, the first air duct is conducted to conduct the suction device 3 and the base station 200. When the air duct switching structure 4 / 4' is not in the first working state, and the air duct 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 collection 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 that when the cleaning device 100 is performing cleaning work, part of the airflow enters the base station 200 and causes the diversion of the airflow, affecting the cleaning effect of the cleaning device 100.

[0092] In a normal household cleaning environment, preferably, the air duct switching structure 4 / 4' can make the cleaning device 100 work in only one of the working states. Among them, when the air duct switching structure 4 / 4' is in the first working state, the air duct switching structure 4 / 4' conducts the first air duct and blocks the second air duct; when the air duct switching structure 4 / 4' is in the second working state, the air duct switching structure 4 / 4' conducts the second air duct and blocks the first air duct. The air duct switching structure 4 / 4' can simultaneously realize the conduction of one of the air ducts and the blocking of another air duct, 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. And 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.

[0093] At this time, preferably, combined with Figures 2 to 4 As shown, the air duct 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 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 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 one of the first air duct and the second air duct to ensure better sewage discharge effect or cleaning effect.

[0094] Furthermore, combined with Figure 3 and Fig.13As shown, the first opening structure includes a first pair of interfaces 411 / 411' and a second pair of interfaces 412 / 412', and the second opening structure includes a third pair of interfaces 413 / 413' and a fourth pair of interfaces. The first pair of interfaces 411 / 411' is suitable for communicating with the suction device 3, the second pair of interfaces 412 / 412' is suitable for communicating with the base station 200, the third pair of interfaces 413 / 413' is suitable for communicating with the dirt collecting chamber 2, and the fourth pair of interfaces is suitable for communicating with the suction device 3. When in the first working state, the first pair of interfaces 411 / 411' is connected with the second pair of interfaces 412 / 412', so that the first air duct is in a conducting state, and the second shielding structure 425 is arranged to block the third pair of interfaces 413 / 413' to block the second air duct, thereby conducting 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, and 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 pair of interfaces 413 / 413' and the fourth pair of interfaces are connected to conduct the second air duct, and the first shielding structure 424 is arranged to block the second pair of interfaces 412 / 412' to block the first air duct, so that the suction device 3 and the dirt collecting chamber 2 are connected, and a blockage is formed between the base station 200 and the suction device 3, and the suction airflow can enter the dirt collecting chamber 2 through the dirt 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.

[0095] It can be understood that the way to achieve the blocking and conduction of the first air duct and the second air duct is not limited to the above one. In another embodiment, the air duct switching structure 4 / 4' may include at least one first barrier and at least one second barrier, at least one first barrier is arranged on the first air duct, and at least one second barrier is arranged on the second air duct. Wherein, each first barrier and each second barrier can be movably arranged to have an open state of the guide air duct and a closed state of the blocked air duct. When each first barrier is in an open state, the first air duct is in a conducting state, and when each first barrier is in a closed state, the first air duct is in a blocked state. By controlling the state of each first barrier to control the conduction and blockage of the communication path between the base station 200 and the suction device 3, one first barrier can be provided, which is convenient to control and simple to operate. Alternatively, multiple first barriers can be provided, and multiple first barriers form multiple blockages on the communication path between the base station 200 and the suction device 3, and the sealing effect is better. The first barrier member may be configured as a movable barrier plate, a mechanical valve or a solenoid valve, etc. The first barrier member may be moved manually or driven by a driver.

[0096] Similarly, when each second barrier is in an open state, the second air duct is in a conducting state, and when each second barrier is in a closed state, the second air duct is in a blocked state. By controlling the state of each second barrier to control the conduction and blocking of the communication 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, a plurality of second barrier members may be provided, and the plurality of second barrier members form multiple blockages on the communication path between the dirt collecting chamber 2 and the suction device 3, and the sealing effect is better. Among them, the second barrier member may be set as a movable barrier plate, a mechanical valve or a solenoid valve. The movement of the second barrier member may be manually moved or driven by a driver.

[0097] Optionally, the first barrier member and the second barrier member may be the same.

[0098] 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 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.

[0099] Among them, under certain circumstances, when one of the first air duct and the second air duct is in a conducting state, the other one can also be in a conducting state, that is, the suction device 3 is connected to the base station 200 and the dirt collecting 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. While the suction force for sucking external dirt can be formed in the dirt collecting chamber 2, the suction force for sucking out the dirt in the dirt collecting chamber 2 can also be formed in the base station 200, and the cleaning device 100 can suck dirt while discharging dirt.

[0100] Specifically, when there are 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 needs to wait for a certain period of time, which makes the operation time-consuming and labor-intensive. Therefore, by connecting the cleaning device 100 with the base station 200, and making the suction device 3 connected with 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, and there is no need to frequently move the cleaning device 100, and there is no need to wait 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 dirt collecting chamber 2 and the suction device 3 and the dirt outlet connecting the dirt collecting chamber 2 and the base station 200 can be arranged on the same side of the dirt collecting chamber 2. Therefore, the airflow entering the dirt collecting chamber 2 can flow in the same direction. A filter component can be arranged at the air outlet. 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 dirt outlet to enter the base station 200, thereby achieving dirt suction and dirt discharge at the same time.

[0101] At this time, the base station 200 can be set to be movable so that it can be moved together with the cleaning device 100 to make the cleaning range wider; or, a longer telescopic connecting pipe can be set between the base station 200 and the cleaning device 100 to better connect the base station 200 and the cleaning device 100, which is more convenient for cleaning when the amount of dirt is large. However, this setting method requires strict control of the suction air flow formed by the suction device 3 to ensure that the air flow entering the base station 200 and the dirt collecting chamber 2 is more balanced, so as to meet the working state of sucking and discharging dirt at the same time.

[0102] It can be understood that, corresponding to each setting mode of the above-mentioned air duct switching structure 4 / 4', the air duct switching structure 4 / 4' can be correspondingly provided with a plurality of movement modes. For example, when the air duct 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 the movement modes, etc. Therefore, the various setting forms and the various movement modes of the air duct switching structure 4 / 4' can be implemented in combination with each other, including but not limited to the implementation modes listed in the present utility model. 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 mode of the air duct switching structure 4 / 4' will be described below in conjunction with specific embodiments.

[0103] Preferably, the air duct switching structure 4 / 4' is rotatably provided on the cleaning device 100, and the air duct switching structure 4 / 4' is rotated to realize the switching between the first working state and the second working state, so that the state adjustment is more convenient and easy to control.

[0104] Specifically, in one embodiment, the first docking port 411 / 411', the second docking port 412 / 412', the third docking port 413 / 413' and the fourth docking port may be arranged on the same circumferential surface so that the channel between the first docking port 411 / 411' and the second docking port 412 / 412' and the channel between the third docking port 413 / 413' and the fourth docking port are non-intersectingly arranged. When the first pair of interfaces 411 / 411' is connected to the suction device 3 and the second pair of interfaces 412 / 412' is connected to the base station 200, the third pair of interfaces 413 / 413' is misaligned with the sewage collecting chamber 2, and the fourth pair of interfaces is misaligned with the suction device 3; when the third pair of interfaces 413 / 413' is connected to the sewage collecting chamber 2 and the fourth pair of interfaces is connected to the suction device 3, the first pair of interfaces 411 / 411' is misaligned with the suction device 3, and the second pair of interfaces 412 / 412' is misaligned with the base station 200. By switching different openings, one of the air ducts is in a connected state with the suction device 3.

[0105] In another embodiment, among the first docking interface 411 / 411', the second docking interface 412 / 412', the third docking interface 413 / 413' and the fourth docking interface, at least one docking interface is arranged at intervals with the other docking interfaces along the axial direction of the circumferential surface, so that one channel is arranged in the radial direction along the circumferential surface, and the other channel is arranged in the axial direction along the circumferential surface. Specifically, the channel between the first docking interface 411 / 411' and the second docking interface 412 / 412' and the channel between the third docking interface 413 / 413' and the fourth docking interface can be arranged in a cross-arrangement, so that the diameter of the circumferential surface can be smaller, so that the structure can be more compact.

[0106] Preferably, the first pairing port 411 / 411 ′ and the fourth pairing port may be integrally provided to reduce the number of openings communicating with the suction device 3 , so that the structure of the air duct switching structure 4 / 4 ′ may be simpler.

[0107] Furthermore, the first mating interface 411 / 411 ′, the third mating interface 413 / 413 ′, the second shielding structure 425 , the first shielding structure 424 and the second mating interface 412 / 412 ′ are sequentially arranged at intervals along the circumferential direction. When in the first working state, the first pair of interfaces 411 and the suction device 3 are in a relative connection state, the third pair of interfaces 413 is offset from the dirt collecting chamber 2, and the second shielding structure 425 is arranged to block the connection between the dirt collecting chamber 2 and the air duct switching structure 4 / 4', the second pair of interfaces 412 / 412' and the base station 200 are in a relative connection state, and the cleaning device 100 is in a sewage discharge state; when in the second working state, the first pair of interfaces 411 / 411' can be rotated to be offset from the suction device 3, the second pair of interfaces 412 / 412' and the suction device 3 are relative connection and conduction, the third pair of interfaces 413 / 413' and the dirt collecting chamber 2 are relative connection and conduction, the first shielding structure 424 blocks the connection between the base station 200 and the air duct switching structure 4 / 4', and the cleaning device 100 enters the cleaning working state. By rotating the air duct switching structure 4 / 4', different openings are adjusted to be connected with the base station 200 and the dirt collecting chamber 2, so as to realize the switching of two working states, and the adjustment is simple and convenient.

[0108] Moreover, the cleaning system 1000 further includes a reversing drive component 43 / 43', which is connected to the air duct switching structure 4 / 4' and is used to drive the air duct switching structure 4 / 4' to rotate, making the state switching of the air duct switching structure 4 / 4' more labor-saving and the operation of the cleaning device 100 more intelligent.

[0109] The air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43', and the air duct switching structure 4 / 4' can enter the first working state when it rotates by a first preset angle. Specifically, the reversing drive component 43 / 43' can have an initial position or a waiting position, and the air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43' by the first preset angle, so that the air duct switching structure 4 / 4' can rotate from the initial position or the waiting position to the first working state. Alternatively, the air duct switching structure 4 / 4' only rotates between the first working state and the second working state, and the air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43', so that the air duct switching structure 4 / 4' can switch from the second working state to the first working state after rotating by the first preset angle.

[0110] Similarly, the air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43', and the air duct switching structure 4 / 4' can enter the second working state when it rotates to the second preset angle. The reversing drive component 43 / 43' can have an initial position or a waiting position, and the air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43', so that when it rotates to the second preset angle, the air duct switching structure 4 / 4' can rotate from the initial position or the waiting position to the second working state. Alternatively, the air duct switching structure 4 / 4' only moves between the first working state and the second working state, and the air duct switching structure 4 / 4' is driven to rotate by the reversing drive component 43 / 43', so that the air duct switching structure 4 / 4' can switch from the first working state to the second working state after rotating to the second preset angle.

[0111] Preferably, the reversing driving component 43 / 43' can drive the air duct switching structure 4 / 4' to rotate, so that the air duct switching structure 4 / 4' only switches between the first working state and the second working state, the rotation stroke is smaller, and the structure can be simpler.

[0112] Wherein, the air duct 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 oppositely arranged, that is, when the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. Driven by the reversing drive component 43 / 43', the air duct switching structure 4 / 4' can be continuously rotated in one direction to be in the first working state and the second working state respectively. Alternatively, when the reversing drive component 43 / 43' drives the air duct switching structure 4 / 4' to rotate in the first direction, the air duct switching structure 4 / 4' can switch from the first working state to the second working state, and when the reversing drive component 43 / 43' drives the air duct switching structure 4 / 4' to rotate in the second direction, the air duct switching structure 4 / 4' switches from the second working state to the first working state.

[0113] It can be understood that the first preset angle and the second preset angle can be the same or different. When the air duct switching structure 4 / 4' has a rotation stroke along the first direction and along 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, and can be set to an obtuse angle, for example, any angle such as 100°, 105°, etc., or an acute angle, for example, 72°, 80°, etc.; or 90°.

[0114] When the reversing driving component 43 / 43' drives the air duct 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 air duct switching structure 4 / 4' in the first working state and the second position of the air duct switching structure 4 / 4' in the second working state are on the same circumferential surface. When the first position and the second position are relatively set along the radial direction of the circumferential surface, the first preset angle and the second preset angle are equal and can 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 air duct switching structure 4 / 4' can rotate continuously in the same direction, so as to be in the first working state and the second working state respectively. Among them, the rotation direction and rotation angle of the air duct switching structure 4 / 4' are not specifically limited, and can be reasonably set according to the internal structure of different cleaning devices 100.

[0115] For the air duct switching structure 4 / 4', in one embodiment, combined with Figure 8 , Fig. 9 , Fig.16 and Fig.18 As shown, the air duct switching structure 4 / 4' includes a reversing shell 41 / 41' and a reversing body, wherein the reversing body is rotatably arranged in the reversing shell 41 / 41' and is drivingly connected to the reversing drive component 43 / 43'; the reversing 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 a first working state, and the reversing body can conduct the second air duct and block the first air duct to be in a 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.

[0116] 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 air duct switching structure 4 / 4' can be fixed in the equipment body 1 together, the assembly accuracy is higher, and it is not easy to produce abnormal noise when the cleaning equipment 100 is working.

[0117] Alternatively, the reversing body and the fan housing are detachably arranged, so that when the fan is assembled with the fan housing, the air duct switching structure 4 / 4' can be assembled at the same time, which increases the overall assembly efficiency and facilitates maintenance.

[0118] Specifically, combined Fig. 9 and Fig.18As shown, the first pair of interfaces 411 / 411', the second pair of interfaces 412 / 412' and the third pair of interfaces 413 / 413' are arranged on the reversing shell 41 / 41', the first pair of interfaces 411 / 411' is connected to the suction device 3, the second pair of interfaces 412 / 412' is connected to the base station 200, and the third pair of interfaces 413 / 413' is connected to the sewage collecting chamber 2; a first channel and a second channel, as well as a first shielding structure 424 and a second shielding structure 425 are formed on the reversing body; when in the first working state, the first channel connects the first pair of interfaces 411 / 411' and the second pair of interfaces 412 / 412', and the second shielding structure 425 blocks the third pair of interfaces 413 / 413'; when in the second working state, the second channel connects the first pair of interfaces 411 / 411' and the third pair of interfaces 413 / 413', and the first shielding structure 424 blocks the second pair of interfaces 412 / 412'. By rotating the reversing body relative to the reversing shell 41 / 41', the first channel on the reversing body is connected to the first docking port 411 / 411' and the second docking port 412 / 412', so that the suction device 3 can be connected to 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 shell 41 / 41', the second channel on the reversing body can be connected to the first docking port 411 / 411' and the third docking port 413 / 413', so that the suction device 3 is connected to 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 achieving the cleaning of external dirt. The switching between the first working state and the second working state is more convenient, and there will be no state in which the suction device 3 is connected to or blocked with the base station 200 and the dirt collecting chamber 2, which can better protect the suction device 3 and the cleaning device 100.

[0119] Furthermore, if Fig. 9 As shown in the figure, the reversing body includes a reversing cylinder 42, and a first opening 421, a second opening 422 and a third opening 423 arranged on the peripheral side wall of the reversing cylinder 42. The first shielding structure 424 and the second shielding structure 425 are also arranged on the peripheral side wall of the reversing cylinder 42.

[0120] In one embodiment, the first opening 421 , the second opening 422 and the third opening 423 are arranged at intervals along the circumference of the reversing cylinder 42 , and the first docking port 411 , the second docking port 412 and the third docking port 413 are arranged at intervals along the circumference of the reversing body. Moreover, the first opening 421, the first shielding structure 424, the second opening 422, the second shielding structure 425 and the third opening 423 are arranged in sequence along a 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 pair of interfaces 411 and the first opening 421 are opposite, the second pair of interfaces 412 and the second opening 422 are opposite, the third pair of interfaces 413 and the third opening 423 are misaligned, and the second shielding structure 425 is arranged to block the third pair of interfaces 413, so that the first pair of interfaces 411 and the second pair of interfaces 412 are connected through the first opening 421 and the second opening 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, the first opening 421 rotates to be opposite to the part between the first docking port 411 and the second docking port 412, the third opening 423 rotates to be opposite to the first docking port 411, the second opening 422 rotates to be opposite to the third docking port 413, and the first shielding structure 424 is set to block the second docking port 412, so that the first docking port 411 and the third docking port 413 are connected through the second opening 422 and the third opening 423, the second air duct is connected, that is, the suction device 3 is connected to the dirt collecting chamber 2, and the air duct switching structure 4 enters the second working state. By rotating the reversing cylinder 42, different openings on the reversing cylinder 42 are relatively connected with the docking ports on the corresponding reversing housing 41 to adjust the working state of the air duct switching structure 4, and the two channels are isolated from each other, which is more convenient for flexible control.

[0121] Preferably, the angle between the first opening 421 and the third opening 423 is 72°, and the angle between the first opening 421 and the second opening 422 is 144°. In the radial direction along the reversing cylinder 42, the center line of the first shielding structure 424 coincides with the bisector of the angle between the first opening 421 and the second opening 422, and the center line of the second shielding structure 425 coincides with the bisector of the angle between the second opening 422 and the third opening 423.

[0122] In another embodiment of the air duct switching structure 4, combined with Fig. 9 and Fig.10As shown, the first opening 421 and the third opening 423 are arranged at intervals along the circumference of the reversing cylinder 42, and the first opening 421 and the second opening 422 are arranged at intervals along the axial direction of the reversing cylinder 42; correspondingly, the first docking port 411 and the third docking port 413 are arranged at intervals along the circumference of the reversing body, and the first docking port 411 and the second docking port 412 are arranged at intervals along the axial direction of the reversing body, so that the spacing between the first docking port 411, the second docking port 412 and the third docking port 413 can be larger, and intervals can be formed along the axial direction of the reversing body, so that each docking port can be better connected with other structures. Specifically, the second docking port 412 can be more conveniently connected to the base station 200, so that the third docking port 413 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.

[0123] At this time, when in the first working state, the first docking port 411 is opposite to the first opening 421, the second docking port 412 is opposite to the second opening 422, and the second shielding structure 425 blocks the third docking port 413, and a first channel is formed between the first opening 421 and the second opening 422, so that when the first docking port 411 is connected to the first opening 421 and the second docking port 412 is connected to the second opening 422, the suction device 3 can be connected to the base station 200, and the third docking port 413 connected to the dirt collecting chamber 2 is closed by the second shielding structure 425. When the suction device 3 is turned on, negative pressure can be formed in the base station 200, so that the dirt in the dirt collecting chamber 2 can be sucked out through the base station 200. When in the second working state, the first pairing port 411 and the third opening 423 are opposite, the third pairing port 413 and the first opening 421 are opposite, and the first shielding structure 424 blocks the second pairing port 412, the first opening 421 and the third opening 423 are connected to form the above-mentioned second channel, when the first pairing port 411 and the third opening 423 are connected and connected, and the third pairing port 413 and the first opening 421 are connected and connected, the suction device 3 can be connected to the dirt collecting chamber 2, and the third opening 423 connected to the base station 200 is in a closed state under the action of the first shielding structure 424, so when the suction device 3 is turned on, negative pressure can be formed in the dirt collecting chamber 2, so that external dirt can be sucked into the dirt collecting chamber 2. The reversing drive component 43 drives the reversing cylinder 42 to rotate, so that different air ducts are connected to the suction device 3, thereby realizing the switching between the first working state and the second working state, which is simple to operate and easy to control.

[0124] Among them, Fig. 9As shown in the figure, the second shielding structure 425 is formed based on the portion between the first opening 421 and the third opening 423, and the first shielding structure 424 and the second 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 a part of the peripheral side wall of the reversing cylinder 42, or alternatively, fixed on the outer side of the peripheral side wall of the reversing cylinder 42.

[0125] Furthermore, if Fig. 9 As shown in , the reversing body can be composed of two parts, and 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 open at one end. The open end of the first shell and the open end of the second shell are connected to each other. The first docking port 411 and the third docking port 413 are arranged on the first shell, and the second docking port 412 is arranged 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.

[0126] Moreover, the reversing cylinder 42 is also provided in two parts, and the reversing cylinder 42 includes a first cylinder section and a second cylinder section connected to each other, and the first cylinder section and the second cylinder section form a rotation-stopping fit in the circumferential direction, so that when one of them rotates, the other can be driven to rotate together. The first opening 421 and the third opening 423 are provided on the first cylinder section, and the second opening 422 is provided on the second cylinder section, and the first cylinder section is rotatably provided in the first shell, and the second cylinder section is rotatably provided in the second shell, so that the assembly is more convenient, and a single cylinder section can be replaced during maintenance, so that the maintenance cost is lower.

[0127] 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 can be sealed between the docking interface and the corresponding opening, thereby ensuring a more reliable seal, making the suction force generated by the suction device 3 more efficient, and thus improving work efficiency.

[0128] Preferably, if Fig. 9As shown in the figure, the reversing drive component 43 includes a reversing driver 431, a driving worm 432 and a driving worm wheel 433, wherein the reversing driver 431 is connected to the driving worm 432, the driving worm 432 is meshed with the driving worm wheel 433, and the driving worm wheel 433 is connected to the reversing cylinder 42. The reversing driver 431 can be provided with a reversing driving motor, which drives the worm 432 to rotate and drives the driving worm wheel 433 to rotate, thereby driving the reversing cylinder 42 to rotate. Specifically, the rotating shaft of the driving worm wheel 433 is connected to the bottom of the first barrel section, and the first barrel section is driven to rotate by the rotation of the driving worm wheel 433, and the second barrel section is driven to rotate together, so that the opening on the reversing cylinder 42 can be shifted to be connected with the corresponding docking port, so as to realize the 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.

[0129] In addition, the air duct switching structure 4 may also include a detection component and a control device, the control device is electrically connected to the detection component and the reversing drive component 43, the detection component is used to detect the position state of the reversing body, and the control device is used to control the working state of the reversing drive component 43 according to the detection result of the detection component. The working state of the air duct switching structure 4 can be monitored in real time, thereby ensuring the accuracy of the working state of the cleaning device 100.

[0130] 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 operation of the air duct switching structure 4 according to the detection signal.

[0131] Among them, the Hall element can be arranged on the reversing body and corresponding to the second docking interface 412 and / or the third docking interface 413, and the detection block is arranged on the reversing cylinder 42 and corresponding to the second opening 422 and / or the third opening 423. For example, when the Hall element is located at the second docking interface 412 and the detection block is detected, it means that the second docking interface 412 is connected to the second opening 422. At this time, the Hall element can send a first detection signal, and the control device determines that the air duct switching structure 4 / 4' is in the first working state at this time according to the first detection signal. Alternatively, a Hall element is also arranged at the third docking interface 413, and a detection block is arranged at the third opening 423. When the Hall element located at the third docking interface 413 detects the detection block located at the third opening 423, a second detection signal can be sent, and the control device can determine that the air duct switching structure 4 is in the second working state at this time according to the second detection signal, and then can control whether the reversing drive component 43 is working according to the demand. There are many settings and positions of the detection component, which are not described in detail here.

[0132] The arrangement of the reversing housing 41' and the reversing body is not limited to the above-mentioned one. In another embodiment, Figures 16 to 19 As shown, the second docking port 412' and the third docking port 413' can be arranged at intervals along the circumference of the reversing housing 41'. At this time, the reversing body may include a reversing shaft 44 and a reversing baffle 45 arranged on one side of the reversing shaft 44. The reversing drive component 43' is connected to the reversing shaft 44 to drive the reversing shaft 44 to rotate, so that the reversing baffle 45 can rotate with the reversing shaft 44 as the rotating shaft. The reversing baffle 45 can respectively block the second docking port 412' and the third docking port 413', so that the first docking port 411' can be connected to the third docking port 413' and the second docking port 412', so as to be in the second working state and the first working state respectively, and the structure is simpler.

[0133] It is understandable that, in one embodiment, the second docking port 412' and the third docking port 413' may be located on both sides of the first docking port 411', respectively. By rotating the reversing body, the reversing body may sequentially pass through the second docking port 412', the first docking port 411' and the third docking port 413', or the reversing body may sequentially pass through the third docking port 413', the first docking port 411' and the second docking port 412', 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 docking port 413', and the reversing shaft 44 is driven to rotate by the reversing drive component 43 / 43' to drive the reversing baffle 45 to rotate from the third opening 423 through the first docking port 411' to the second docking port 412', thereby blocking the second docking port 412', 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 pass through the second pair of ports 412', the first pair of ports 411' and the third pair of ports 413' in sequence, and can achieve blocking of any pair of ports, which is more flexible and diverse.

[0134] Preferably, combined Figures 16 to 19As shown, the second docking port 412' and the third docking port 413' may be located on the same side of the first docking port 411'. By rotating the reversing body, the reversing body can be reciprocated and switched between the second docking port 412' and the third docking port 413'. For example, when the cleaning device 100 is in a cleaning state of sucking dirt, the reversing body is arranged to block the second docking port 412'. After cleaning, 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 docking port 413' 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 docking port 412' and the third docking port 413', and does not pass through the first docking port 411'. The rotation path is shorter, so the switching speed is faster.

[0135] Correspondingly, the arrangement of the reversing drive component 43' is also different. Fig.16 and Fig.17 As shown in the figure, the reversing drive component 43' is arranged outside the reversing housing 41' and connected to one end of the reversing shaft 44. The reversing drive component 43' may include a shielding driver 46, which drives the reversing shaft 44 to rotate to realize the automatic movement of the reversing baffle 45.

[0136] Specifically, the reversing baffle 45 has a shielding portion extending along the circumference of the reversing shaft 44. The shielding portion can shield the second opening 422 and the third opening 423 respectively under the drive of the shielding driver 46. The shielding portion forms the above-mentioned first shielding structure 424 and the second shielding structure 425 to achieve the switching between the first working state and the second working state. The shielding portion can be a part of the reversing baffle 45, or the shielding portion can be detachably connected to the reversing baffle 45, and the shielding portion is respectively clamped at the second opening 422 and the third opening 423 to form a blockage for the second opening 422 and the third opening 423.

[0137] Moreover, the air duct switching structure 4' also includes a driving handle, wherein an adjustment groove is provided on one of the driving handle and the reversing shaft 44, wherein an adjustment protrusion which is plugged and matched with the adjustment groove is provided on the other. When the driving handle is rotated by an external force, the reversing rotation can be driven to rotate together under the cooperation of the adjustment groove and the adjustment protrusion, so that a stop fit is formed between the driving handle and the reversing shaft 44. When the reversing driving component 43' fails to work normally, the driving handle 5 can be rotated manually, thereby driving the reversing shaft 44 and the reversing baffle 45 to rotate together, so as to realize the switching of the air duct switching structure 4' between the first working state and the second working state. The air duct switching structure 4' can be driven by two driving modes: manual drive and drive motor drive. When the reversing driving component 43' fails to work normally, the working state can be switched by manual operation, which is more flexible and has a wider range of adaptability.

[0138] In this embodiment, the combination Fig.17 As shown, the reversing shell 41' includes a cavity body and an extension part. The cavity body is roughly fan-shaped and cylindrical, and the interior is hollow. The extension part protrudes on one side of the cavity body. The first docking port 411', the second docking port 412' and the third docking port 413' are arranged in sequence along the circumference of the cavity body, and the extension part extends outward from the circumference of the first docking port 411' to form an interface suitable for docking with the suction device 3. The reversing baffle 45 is arranged on the inner side of the cavity body, and the reversing baffle 45 is provided with a through hole that runs through the circumference of the reversing shell 41'. When the reversing baffle 45 is in the second working state, the first docking port 411' and the third docking port 413' 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.

[0139] Furthermore, if Fig.19 As shown in the figure, the cavity body has a first inner wall 414, a second inner wall 415, and a transition wall 416 connecting the first inner wall 414 and the second inner wall 415, the first inner wall 414 and the third inner wall respectively form two side walls of a fan shape, the transition wall 416 is an arc-shaped fan-shaped wall, the first docking port 411' is arranged on the first inner wall 414, the second docking port 412' and the third docking port 413' are arranged on the transition wall 416, and the shape of the shielding portion is adapted to the shape of the transition wall 416, that is, the shielding portion is also arranged in an arc shape, so as to better block the second docking port 412' and the third docking port 413' arranged in an arc shape.

[0140] Moreover, the cavity body has a bottom wall connected to the first inner wall 414, the second inner wall 415 and one end of the transition wall 416, and also has a top wall detachably arranged with the first inner wall 414, the second inner wall 415 and the transition wall 416, the reversing shaft 44 is rotatably arranged on the top wall, and a guide cylinder is arranged on the cavity body. After the reversing shaft 44 is rotatably arranged on the top wall, the top wall cover with the reversing body installed is arranged on the first inner wall 414, the second inner wall 415 and the transition wall 416, and the reversing shaft 44 is rotatably arranged in the guide cylinder, so as to close the cavity body. The assembly of the reversing body is not limited to the internal space of the cavity body, the assembly is more convenient, and the subsequent maintenance is also convenient to disassemble, and the maintenance cost is also lower.

[0141] Further, the air duct switching structure 4' also includes a limiting structure. In the rotation direction, the limiting structure can limit the rotation direction of the reversing cylinder 42 to avoid the wrong rotation direction, which leads to the failure of the connection. For example, when the reversing cylinder 42 is in the first working state, it can be switched to the second working state by rotating in the clockwise direction. In the counterclockwise direction, the limiting structure can form a stop fit with the reversing cylinder 42 to prevent the reversing cylinder 42 from rotating in the counterclockwise direction. When the reversing cylinder 42 is in the second working state, rotating the reversing cylinder 42 in the counterclockwise direction can make the air duct switching structure 4 / 4' reset to the first working state. The limiting structure forms a stop fit with the reversing cylinder 42 in the clockwise direction, thereby preventing the reversing cylinder 42 from continuing to rotate in the clockwise direction when it is in the first working state, so as to ensure the adjustment stability of the reversing cylinder 42. Among them, the limiting structure can be set as a stop protrusion, and the stop protrusion cooperates with the side wall of the reversing cylinder 42 to form a stop.

[0142] Specifically, for the reversing baffle 45, in combination with Fig.21 and Fig. 22 As shown, the reversing baffle 45 has a first stop wall 451 and a second stop wall 452 which are arranged in a divergent manner 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 415 to prevent the reversing baffle 45 from continuing to rotate in the direction from the second docking port 412' to the third docking port 413', to prevent the reversing baffle 45 from rotating too much and failing to completely close the third docking port 413', and to indicate that the reversing baffle 45 has rotated to the right 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 414 to prevent the reversing baffle 45 from continuing to rotate in the direction from the third docking port 413' to the second docking port 412', to prevent the reversing baffle 45 from rotating too much and failing to completely close the second docking port 412', and to indicate that the reversing baffle 45 has rotated to the right position and can stop rotating.

[0143] Moreover, the material of the end of the reversing baffle 45 facing away from the reversing shaft 44, that is, the end of the reversing baffle 45 that closes the second docking interface 412' and the third docking interface 413' is an elastic material, and the elastic material allows the reversing baffle 45 to be in closer contact with the second docking interface 412' and the third docking interface 413', and the sealing effect is better. Alternatively, a sealing member is bonded to the end of the reversing baffle 45 facing away from the reversing shaft 44, and the gap between the reversing baffle 45 and the second docking interface 412' and the third docking interface 413' can be closed by the sealing member to ensure a better sealing effect. Among them, the sealing member can be set as a sealing pad or a sealing ring, and the material of the sealing member can be an elastic material such as rubber or sponge.

[0144] Wherein, a Hall element may be provided on the first inner wall 414 and / or the second inner wall 415, 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 place, the Hall element on the first inner wall 414 can detect the detection on the first stop wall 451, thereby sending a second detection signal to the control device to indicate that the air duct switching structure 4' is in the second working state. When the second stop wall 452 is rotated into place, the Hall element on the second inner wall 415 can detect the detection on the second stop wall 452, thereby sending a first detection signal to the control device to indicate that the air duct switching structure 4' is in the first working state. Alternatively, the above-mentioned Hall element is provided corresponding to the second docking interface 412' and / or the third docking interface 413', and the detection block is provided on the reversing baffle 45. Similarly, the Hall element sends different detection signals to indicate that the air duct switching structure 4' is in different working states. Then, the control device controls the reversing drive component 43 / 43' to work according to different detection signals, so that the reversing drive component 43' can be stopped in time after the reversing baffle 45 rotates to the right position, which is more energy-saving and intelligent.

[0145] In addition, combined Figures 16 to 18 As shown, the cleaning device 100 is also provided with an air duct docking structure 5, through which the second docking interface 412' 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 docking interface 412', 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 outer surface of the cleaning device 100. When the cleaning device 100 is docked with the base station 200, the second air guide port 42 can be connected to the airflow duct on the base station 200, so that the suction device 3 on the cleaning device 100 can be connected to the second docking interface 412' and the second air guide port 52, and thus connected to the base station 200. When the suction device 3 is working, negative pressure can be formed in the base station 200.

[0146] 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 is connected to the clean water tank, and preferably, the guide port 53 and the second air guide port 52 are located on the same side. When the cleaning device 100 is docked with the base station 200, the guide port 53 may be connected to a water supply device (such as a base station clean water tank or a tap water pipe docking joint) on the base station 200, so that the base station 200 can realize automatic water supply to the clean water tank on the cleaning device 100, and 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 occupying less space.

[0147] Moreover, the base station 200 can be provided with only a storage cavity for storing waste, without providing a base station clean water tank, which makes the structure simpler. When water replenishment is needed, clean water is directly replenished to the clean water tank of the cleaning device from the tap water pipe through the three-way valve, which makes the structure simpler and the base station 200 lighter.

[0148] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
