[0050] Example 1

[0051] The present application provides a cleaning system 1000, please refer to Figures 1 to 3, the cleaning system 1000 includes a base station 200, a cleaning device 100, an air duct switching structure 4 / 4' and a reversing drive structure 43 / 43', wherein the cleaning device 100 includes a suction device 3, the air duct switching structure 4 / 4' is movably arranged on the base station 200 or the cleaning device 100, and the reversing drive structure 43 / 43' is connected to the air duct switching structure 4 / 4' to drive the air duct switching structure 4 / 4' to move; when the cleaning device 100 is docked with the base station 200, the air duct switching structure 4 / 4' can connect the suction device 3 and the base station 200, so that the suction force generated by the suction device 3 enters the base station 200 to suck the dirt into the base station 200.

[0052] In this embodiment, the reversing drive structure 43 / 43' is an electric drive structure. The reversing drive structure 43 / 43' drives the air duct switching structure 4 / 4' to move, so that when the cleaning device 100 is connected to the base station 200, the air duct switching structure 4 / 4' can connect the suction device 3 and the base station 200, so that a negative pressure is formed in the base station 200 to suck out the dirt in the dirt collection chamber 2 of the cleaning device 100, thereby achieving self-cleaning of the dirt collection chamber 2 on the cleaning device 100; or, the suction device 3 is connected to the cleaning tank on the base station 200 to remove dirt formed by the cleaning parts of the cleaning device 100 during the cleaning process; or, the suction device 3 is connected to the dirt storage chamber on the base station 200 to suck and compress the garbage in the dirt storage chamber. Therefore, there is no need to set up a separate fan on the base station 200 to clean the cleaning device 100, which is more cost-effective, and the structure of the base station 200 can also be simpler, making it more convenient to install and maintain the base station 200.

[0053] Among them, there is a first air duct connected between the suction device 3 and the base station 200, and the first air duct can be set 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 air flow channel, and the second air duct section is formed on the cleaning equipment 100, and a docking port is provided on the cleaning equipment 100, and the suction device 3 and the docking port are connected through the second air duct section. When the cleaning equipment 100 is placed on the base station 200, the docking port is connected to the air flow channel of the base station 200, and the air duct switching structure 4 / 4' is driven to move by the reversing driving structure 43 / 43' to connect the first air duct section and the second air duct section, thereby connecting the suction device 3 and the base station 200. The suction force generated by the suction device 3 forms a negative pressure in the air flow channel of the base station 200, and then the negative pressure can form a suction force in the place to be cleaned or to be treated that is connected to the air flow channel, so that the dirt in the place to be cleaned can be sucked into the air flow channel or the dirt in the place to be treated can be deformed and compressed under the action of the suction force, etc., making the functions of the base station 200 more diverse, and the base station 200 does not need to provide additional power for dirt treatment, which is more energy-saving and the structure of the base station 200 is also simpler.

[0054] For the cleaning device 100, as shown in Figures 2 and 3, the cleaning device 100 also includes a dirt collecting chamber 2. The reversing driving structure 43 / 43' drives the air duct switching structure 4 / 4' to move, so that the air duct switching structure 4 / 4' can connect the suction device 3 and the dirt collecting chamber 2, so that when the suction device 3 is working, the suction device 3 can form a negative pressure in the dirt collecting chamber 2, and the external dirt can be temporarily stored in the dirt collecting chamber 2 to achieve the cleaning work of the cleaning device 100.

[0055] Moreover, as shown in FIG3 , a second air duct is connected between the suction device 3 and the dirt collecting chamber 2 , and the air duct switching structure 4 / 4' is driven to move by the reversing driving structure 43 / 43', so that the air duct switching structure 4 / 4' has a second connected state in which the second air duct is kept connected. It can be understood that a dirt suction port is also provided on the cleaning device 100, and the dirt suction port can be oriented toward the bottom surface, such as the location to be cleaned (such as the ground) or the cleaning tank of the base station. The dirt suction port is connected to the dirt collecting chamber 2, so that under the action of the suction device 3, external dirt can enter the dirt collecting chamber 2 from the dirt suction port of the cleaning device 100.

[0056] It can be understood that the air duct switching structure 4 / 4' can be set on the cleaning equipment 100, or can be set on the base station 200, or the air duct switching structure 4 / 4' can be an independent structure to be set independently of the cleaning equipment 100 and the base station 200; or, the air duct switching structure 4 / 4' is provided with multiple sets, so that at least one set of air duct switching structure 4 / 4' is respectively provided on the base station 200 and the cleaning equipment 100 to ensure that the air duct switching structure 4 / 4' can connect the suction device 3 and the base station 200.

[0057] Preferably, the air duct switching structure 4 / 4' is provided on the cleaning device 100, so that the air duct switching structure 4 / 4' can connect the suction device 3 and the base station 200, and can also connect the suction device 3 and the dirt collecting chamber 2 on the cleaning device 100. The air duct switching structure 4 / 4' can realize the switching between the two working states of the cleaning device 100. The following description will be based on the example of the air duct switching structure 4 / 4' provided on the cleaning device 100. Other embodiments can be implemented adaptively with reference to this.

[0058] In one embodiment, the operating states of the first and second air ducts are independent of each other and do not affect each other. That is, when the air duct switching structure 4 / 4' opens the first air duct, the second air duct can be opened or blocked; and when the air duct switching structure 4 / 4' blocks the first air duct, the second air duct can be opened or blocked. The air duct switching structure 4 / 4' can control the states of the first and second air ducts separately, making the state adjustment of each air duct more flexible and thus providing more diverse connection methods.

[0059] Specifically, the air duct switching structure 4 / 4' may include multiple blocking plates, with at least one blocking plate being provided at each air duct opening or within the air duct. The blocking plates are opened and closed to open and close the air ducts. When switching the operating state of the cleaning device 100, the positions of the blocking plates can be controlled to control the states of the first and second air ducts, making adjustment simple and convenient.

[0060] Preferably, in the first connected state, the reversing driving structure 43 / 43' can drive the air duct switching structure 4 / 4' to move to block the second air duct, so that when the suction device 3 is connected to the base station 200, the second air duct remains in a blocked state to avoid causing the air flow to be diverted and affecting the suction effect of the base station 200.

[0061] Similarly, in the second connected state, the reversing driving structure 43 / 43' can drive the air duct switching structure 4 / 4' to move to block the first air duct, so that when the suction device 3 is connected to the sewage collecting chamber 2, the first air duct remains in a blocked state, avoiding the formation of airflow imbalance in the sewage collecting chamber 2, which affects the sewage suction effect.

[0062] The switching speeds of the first and second air ducts can be set differently. That is, after the first air duct is in the open state, the second air duct is switched to the blocked state, or after the second air duct is in the blocked state, the first air duct is controlled to be in the open state, so as to better control each air duct.

[0063] Preferably, the switching speeds of the first and second air ducts are synchronized. That is, when the first air duct is in the open state, the second air duct is simultaneously blocked; when the first air duct is in the blocked state, the second air duct is simultaneously opened, thereby preventing the two air ducts from being opened or blocked simultaneously, thereby preventing damage to the suction device 3 and affecting the normal operation of the entire cleaning device 100.

[0064] Specifically, as shown in Figures 2 and 3 , the air duct switching structure 4 / 4' has a first connected state in which it connects to the first air duct and blocks the second air duct, and a second connected state in which it connects to the second air duct and blocks the first air duct. The reversing drive structure 43 / 43' drives the air duct switching structure 4 / 4' to move to switch between the first connected state and the second connected state. The reversing drive structure 43 / 43' drives the air duct switching structure 4 / 4' to move, so that when the suction device 3 is connected to the base station 200, the suction device 3 and the dirt collecting chamber 2 are kept in a blocked state, thereby increasing the suction force within the base station 200 and achieving a better cleaning effect. Furthermore, when the suction device 3 is connected to the dirt collecting chamber 2, the suction device 3 and the base station 200 are kept in a blocked state, so that the suction force generated by the suction device 3 can be fully used to suck dirt from the cleaning device 100, thereby increasing the cleaning efficiency of the cleaning device 100 and achieving a better cleaning effect.

[0065] The air duct switching structure 4 / 4' can move in a variety of ways. For example, the air duct switching structure 4 / 4' can reciprocate in a straight line, or in an arc, or in a circular trajectory. The movement of the air duct switching structure 4 / 4' switches between the first and second connected states, thereby switching between the two operating states of the cleaning device 100.

[0066] Preferably, the air duct switching structure 4 / 4' is rotatably arranged. The reversing drive structure 43 / 43' drives the air duct switching structure 4 / 4' to rotate in a first direction by a first preset angle, so that the air duct switching structure 4 / 4' can switch from the first connected state to the second connected state. The reversing drive structure 43 / 43' drives the air duct switching structure 4 / 4' to rotate in a second direction by a second preset angle to switch from the second connected state to the first connected state. This makes the state switching of the air duct switching structure 4 / 4' more flexible and convenient, thereby achieving faster switching speed and higher efficiency.

[0067] The first direction and the second direction may be in the same direction or in opposite directions. For example, on a circumferential surface along which the air duct switching structure 4 / 4' rotates, when in the first connected state, the air duct switching structure 4 / 4' is in the first position of the circumferential surface, and when in the second connected state, the air duct switching structure 4 / 4' is in the second position of the circumferential surface. The first direction is clockwise. When the air duct switching structure 4 / 4' rotates clockwise by a first preset angle, it reaches the second position, thereby entering the second connected state. Then, when the air duct switching structure 4 / 4' continues to rotate clockwise by a second preset angle, it rotates from the second position to the first position, thereby restoring from the second connected state to the first connected state. Alternatively, when the air duct switching structure 4 / 4' rotates clockwise by a first preset angle, it reaches the second position, thereby entering the second connected state. Then, when the air duct switching structure 4 / 4' continues to rotate counterclockwise by a second preset angle, it rotates from the second position to the first position, thereby restoring from the second connected state to the first connected state. It can be seen that through the two rotation methods, the air duct switching structure 4 / 4' can realize the switching between the first connection state and the second connection state, but when the first direction and the second direction are opposite, the rotation path of the air duct switching structure 4 / 4' can be set shorter, so that the volume of the entire air duct switching structure 4 / 4' can be set smaller, saving more space.

[0068] It will be appreciated that the first preset angle and the second preset angle may be the same or different. When the first direction and the second direction are opposite to each other, the first preset angle and the second preset angle may be equal. When the first direction and the second direction are the same, if the first position and the second position are opposite to each other along the radial direction of the circumferential surface, the first preset angle and the second preset angle may both be 180°. When the angle between the first position and the second position is less than 180° and the first preset angle is θ, the second preset angle is 360°-θ.

[0069] As for the air duct switching structure 4 / 4', in one embodiment, in combination with Figures 4 and 8, the air duct switching structure 4 / 4' includes a reversing shell 41 / 41' and a switching member 42 / 42', wherein the switching member 42 / 42' is rotatably arranged in the reversing shell 41 / 41' and is connected to the reversing driving structure 43 / 43'; the reversing driving structure 43 / 43' drives the switching member 42 / 42' to rotate, so that the switching member 42 / 42' can conduct the first air duct and block the second air duct to be in a first connected state, and the switching member 42 / 42' can conduct the second air duct and block the first air duct to be in a second connected state, and the switching between the first connected state and the second connected state is realized by the rotation of the switching member 42 / 42'.

[0070] Preferably, a first docking port 411 / 411', a second docking port 412 / 412' and a third docking port 413 / 413' are provided on the reversing housing 41 / 41'. The first docking port 411 / 411' is connected to the suction device 3, the second docking port 412 / 412' is connected to the base station 200, and the third docking port 413 / 413' is connected to the sewage collecting chamber 2; a first channel and a second channel, as well as a first shielding member 42 / 42' are formed on the switching member 42 / 42'. Structure 424 and the second shielding structure 425; when in the first connected state, the first channel connects the first docking interface 411 / 411' and the second docking interface 412 / 412', and the second shielding structure 425 blocks the third docking interface 413 / 413'; when in the second connected state, the second channel connects the first docking interface 411 / 411' and the third docking interface 413 / 413', and the first shielding structure 424 blocks the second docking interface 412 / 412'. By rotating the switching member 42 / 42' relative to the reversing shell 41 / 41', the first channel on the switching member 42 / 42' can be 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 negative pressure can be formed in the base station 200 to suck out the dirt in the dirt collecting chamber 2 of the cleaning equipment 100; by rotating the switching member 42 / 42' relative to the reversing shell 41 / 41', the second channel on the switching member 42 / 42' 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 suction port of the cleaning equipment 100, thereby realizing the cleaning of external dirt. The switching between the first connection state and the second connection 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.

[0071] In one embodiment, a first opening 421 , a second opening 422 and a third opening 423 are provided on the peripheral sidewall of the switching member 42 / 42 ′. The first shielding structure 424 and the second shielding structure 425 are also provided on the peripheral sidewall of the switching member 42 / 42 ′.

[0072] In one embodiment, the first opening 421, the second opening 422 and the third opening 423 are spaced apart along the circumference of the switching member 42 / 42', and the first docking port 411 / 411', the second docking port 412 / 412' and the third docking port 413 / 413' are spaced apart along the circumference of the reversing housing 41 / 41'. 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 one direction on the circumference of the switching member 42 / 42'. Looking in the cross-sectional direction toward the reversing shell 41 / 41', when in the first connected state, the first docking interface 411 / 411' is opposite to the first opening 421, the second docking interface 412 / 412' is opposite to the second opening 422, the third docking interface 413 / 413' is staggered with the third opening 423, and the second shielding structure 425 is arranged to block the third docking interface 413 / 413', so that the first docking interface 411 / 411' and the second docking interface 412 / 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 switching member 42 / 42' is driven to rotate, the first opening 421 is rotated to be opposite to the part between the first docking port 411 / 411' and the second docking port 412 / 412', the third opening 423 is rotated to be opposite to the first docking port 411 / 411', the second opening 422 is rotated to be opposite to the third docking port 413 / 413', and the first shielding structure 424 is set to block the second docking port 412 / 412', so that the first docking port 411 / 411' and the third docking port 413 / 413' are connected through the second opening 422 and the third opening 423, and the second air duct is connected, that is, the suction device 3 is connected to the sewage collecting chamber 2, and the air duct switching structure 4 / 4' enters the second connected state. By rotating the switching member 42 / 42', different openings on the switching member 42 / 42' are relatively connected to the corresponding docking ports on the reversing housing 41 / 41' to adjust the working state of the air duct switching structure 4 / 4'. The two channels are isolated from each other, which is more convenient for flexible control.

[0073] 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 switching member 42 / 42 ′, the centerline 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 centerline of the second shielding structure 425 coincides with the bisector of the angle between the second opening 422 and the third opening 423.

[0074] In another embodiment of the air duct switching structure 4, as shown in Figures 4 and 5, the first opening 421 and the third opening 423 are arranged at intervals along the circumference of the switching member 42, and the first opening 421 and the second opening 422 are arranged at intervals along the axial direction of the switching member 42; correspondingly, the first docking port 411 and the third docking port 413 are arranged at intervals along the circumference of the reversing shell 41, and the first docking port 411 and the second docking port 412 are arranged at intervals along the axial direction of the reversing shell 41, 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 a gap can be formed in the axial direction of the reversing shell 41, 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 collecting chamber 2, so that there is enough space to arrange the connecting structure, which can better meet the docking requirements of different devices.

[0075] At this time, when in the first connected state, as shown in Figures 2, 5, and 7, 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, forming a first channel between the first opening 421 and the second opening 422. Therefore, 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, which is 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 connection state, as shown in Figures 3, 5, and 6, the first docking port 411 and the third opening 423 are opposite each other, the third docking port 413 is opposite the first opening 421, and the first shielding structure 424 blocks the second docking port. The first opening 421 and the third opening 423 are connected to form the aforementioned second channel. When the first docking port 411 and the third opening 423 are connected and connected, and the third docking port 413 and the first opening 421 are connected and connected, the suction device 3 can be connected to the sewage collecting chamber 2, and the third opening 423 connected to the base station 200 is in a closed state due to 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 collecting chamber 2, allowing external waste to be sucked into the sewage collecting chamber 2. The reversing drive structure 43 drives the switching member 42 to rotate, so that different air ducts are connected to the suction device 3, thereby achieving switching between the first connection state and the second connection state. The operation is simple and easy to control.

[0076] 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 switching member 42. The first shielding structure 424 and the second shielding structure 425 can be part of the peripheral sidewall of the switching member 42, or alternatively, the first shielding structure 424 and the second shielding structure 425 can be sheet-like structures fixed to the outer side of the peripheral sidewall of the switching member 42.

[0077] Furthermore, as shown in Figure 5, the reversing housing 41 can be composed of two parts. The reversing housing 41 includes a first housing and a second housing that are detachably connected. The first housing and the second housing are connected and arranged along the axial direction. The first housing and the second housing are both roughly cylindrical and open at one end. The open end of the first housing and the open end of the second housing are connected to each other. The above-mentioned first docking port 411 and the third docking port 413 are provided on the first housing, and the above-mentioned second docking port 412 is provided on the second housing, so that after the switching member 42 is installed in the reversing housing 41, the first housing and the second housing can be completely fixed.

[0078] Furthermore, the switching member 42 is also configured in two parts. The switching member 42 is generally cylindrical and includes a first barrel section and a second barrel section that are connected. The first barrel section and the second barrel section form a circumferentially fixed engagement, so that when one barrel section rotates, the other barrel section can also rotate. The first opening 421 and the third opening 423 are provided on the first barrel section, while the second opening 422 is provided on the second barrel section. The first barrel section is rotatably mounted within the first housing, while the second barrel section is rotatably mounted within the second housing. This makes assembly more convenient and allows for individual barrel section replacement during maintenance, thereby reducing maintenance costs.

[0079] 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 shell 41, and the sealing sheet or the flexible sealing piece may 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.

[0080] Preferably, as shown in FIG5 , the reversing drive structure 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 switching member 42. The reversing driver 431 can be provided with a reversing drive motor, which drives the driving worm 432 to rotate, thereby driving the driving worm wheel 433 to rotate, thereby driving the switching member 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 rotation of the driving worm wheel 433 drives the first barrel section to rotate, and drives the second barrel section to rotate together, so that the opening on the switching member 42 can be shifted to connect with the corresponding docking port, thereby realizing the switching between the first connection state and the second connection 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.

[0081] In addition, the air duct switching structure 4 may further include a detection component and a control device. The control device is electrically connected to the detection component and the reversing drive structure 43. The detection component is used to detect the position of the switching member 42, and the control device is used to control the working state of the reversing drive structure 43 based on the detection result of the detection component. This allows the working state of the air duct switching structure 4 to be monitored in real time, thereby further ensuring the accuracy of the working state of the cleaning device 100.

[0082] 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.

[0083] Among them, the Hall element can be set on the reversing housing 41 and corresponding to the second docking port 412 and / or the third docking port 413, and the detection block is set on the switching member 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 port 412 and detects the detection block, it means that the second docking port 412 and the second opening 422 are connected. 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 connection state based on the first detection signal. Alternatively, a Hall element is also provided at the third docking port 413, and a detection block is provided at the third opening 423. When the Hall element located at the third docking port 413 detects the detection block located at the third opening 423, a second detection signal can be sent. The control device can determine that the air duct switching structure 4 is in the second connection state based on the second detection signal, and then can control whether the reversing drive structure 43 is working according to demand. There are many ways and positions of setting the detection components, which are not described in detail here.

[0084] The arrangement of the reversing housing 41 / 41' and the switching member 42 / 42' is not limited to the above-described arrangement. In another embodiment, as shown in FIG8 and FIG9 , the second docking port 412' and the third docking port 413' can be arranged at intervals along the circumference of the reversing housing 41'. In this case, the switching member 42' can include a reversing shaft 44 and a reversing baffle 45 disposed on one side of the reversing shaft 44. The reversing driving structure 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 docking port 412' and the third docking port 413', so that the first docking port 411' can communicate with the third docking port 413' and the second docking port 412', respectively, to be in the second communication state and the first communication state, respectively. The structure is simpler, and the reversing baffle 45 forms the above-mentioned first shielding structure 424 and second shielding structure 425.

[0085] It is understandable that, in one embodiment, the second docking port 412' and the third docking port 413' can be located on both sides of the first docking port 411', respectively. By rotating the switching member 42', the switching member 42' can pass through the second docking port 412', the first docking port 411' and the third docking port 413' in sequence, or the switching member 42' can pass through the third docking port 413', the first docking port 411' and the second docking port 412' in sequence to achieve switching between the first connection state and the second connection 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 driving structure 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 switching member 42 ′ can sequentially pass through the second pair of interfaces 412 ′, the first pair of interfaces 411 ′ and the third pair of interfaces 413 ′, and can achieve blocking of any pair of interfaces, which is more flexible and diverse.

[0086] Preferably, in combination with Figures 9 and 10, 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 switching member 42', the switching member 42' can be moved back and forth 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 switching member 42' is set to block the second docking port 412'. After cleaning is completed, the switching member 42' can be driven to rotate the first preset angle in a clockwise direction so that the switching member 42' is rotated to block the third docking port 413' to enter the sewage discharge state in which the suction device 3 is connected to the base station 200. The switching member 42' 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, and the switching speed is faster.

[0087] Correspondingly, the configuration of the aforementioned reversing drive structure 43' is also different. As shown in FIG9 , the reversing drive structure 43' is disposed outside the reversing housing 41' and connected to one end of the reversing shaft 44. The reversing drive structure 43' may include a blocking actuator 46, which drives the reversing shaft 44 to rotate, thereby achieving automatic movement of the reversing baffle 45.

[0088] Furthermore, the air duct 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 rotation, thereby forming a rotation-stopping fit between the drive handle and the reversing shaft 44. When the reversing drive structure 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 air duct switching structure 4' between the first connection state and the second connection state. The air duct switching structure 4' can be driven by both manual drive and drive motor drive. When the reversing drive structure 43' fails to operate normally, the operating state can be switched manually, which provides greater flexibility and a wider range of adaptability.

[0089] In this embodiment, as shown in Figure 8, 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 provided on the inner side of the cavity body, and a through hole is provided on the reversing baffle 45 along the circumference of the reversing shell 41'. When the reversing baffle 45 is in the second connected 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.

[0090] 9 and 10 , 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, and the transition wall 416 is an arc-shaped fan-shaped wall. The first docking port 411 is provided on the first inner wall 414, and the second docking port 412' and the third docking port 413' are provided on the transition wall 416. The shape of the end face of the reversing baffle 45 facing away from the reversing shaft 44 is adapted to the shape of the transition wall 416, that is, the end face of the reversing baffle 45 facing the transition wall 416 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.

[0091] Furthermore, 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 that is detachably mounted on the first inner wall 414, the second inner wall 415, and the transition wall 416. The reversing shaft 44 is rotatably mounted on the top wall. A guide cylinder is provided on the cavity body. After the reversing shaft 44 is rotated and passed through the top wall, the top wall cover with the switching member 42' installed is then mounted on the first inner wall 414, the second inner wall 415, and the transition wall 416, and the reversing shaft 44 is rotated and passed through the guide cylinder, thereby sealing the cavity body. The assembly of the switching member 42' is not limited to the internal space of the cavity body, making assembly more convenient. It is also easy to disassemble for subsequent maintenance, resulting in lower maintenance costs.

[0092] Furthermore, 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 switching member 42' to avoid incorrect rotation direction and failure of connection. For example, when the switching member 42' is in the first connection state, it can be switched to the second connection state by rotating it in the clockwise direction. In the counterclockwise direction, the limiting structure can form a stop fit with the switching member 42' to prevent the switching member 42' from rotating in the counterclockwise direction. When the switching member 42' is in the second connection state, rotating the switching member 42' in the counterclockwise direction can reset the air duct switching structure 4' to the first connection state. The limiting structure and the switching member 42' form a stop fit in the clockwise direction, thereby preventing the switching member 42' from continuing to rotate in the clockwise direction when in the first connection state, thereby ensuring the adjustment stability of the switching member 42'. The limiting structure can be configured as a stop protrusion, and the stop protrusion cooperates with the side wall of the switching member 42' to form a stop.

[0093] Specifically, the reversing baffle 45 has a first stop wall and a second stop wall disposed in opposite directions along the circumference of the reversing shaft 44. When the switching member 42' is in the first connected state, the second stop wall forms a stop fit with the second inner wall 415 to prevent the reversing baffle 45 from continuing to rotate along the second docking port 412' toward the third docking port 413', thereby preventing the reversing baffle 45 from rotating too far and failing to completely close the third docking port 413'. This also indicates that the reversing baffle 45 has reached its final position and can be stopped. When the switching member 42' is in the second connected state, the first stop wall forms a stop fit with the first inner wall 414 to prevent the reversing baffle 45 from continuing to rotate along the third docking port 413' toward the second docking port 412'. This prevents the reversing baffle 45 from rotating too far and failing to completely close the second docking port 412'. This also indicates that the reversing baffle 45 has reached its final position and can be stopped.

[0094] 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 and third docking ports 412 and 413, is made of an elastic material. This elastic material allows the reversing baffle 45 to more closely contact the second and third docking ports 412' and 413', resulting in a better sealing effect. Alternatively, a sealing member is adhered to the end of the reversing baffle 45 facing away from the reversing shaft 44. The sealing member is annular and can seal the gap between the reversing baffle 45 and the second and third docking ports 412' and 413' to ensure a better sealing effect. The sealing member can be a sealing gasket or a sealing ring, etc., and the material of the sealing member can be an elastic material such as rubber or sponge.

[0095] Moreover, 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 and / or the second stop wall. When the first stop wall is rotated into place, the Hall element on the first inner wall 414 can detect the detection on the first stop wall, thereby sending a second detection signal to the control device to indicate that the air duct switching structure 4' is in the second connected state. When the second stop wall is rotated into place, the Hall element on the second inner wall 415 can detect the detection on the second stop wall, thereby sending a first detection signal to the control device to indicate that the air duct switching structure 4' is in the first connected 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 driving structure 43' to work according to different detection signals, so that the reversing driving structure 43' can be stopped in time after the reversing baffle 45 rotates to the right position, which is more energy-saving and intelligent.

[0096] In addition, as shown in Figures 8 and 9, the cleaning device 100 is further 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 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 air duct on the base station 200.

[0097] In one embodiment, when the cleaning device 100 is also provided with a clean water tank, a guide port 53 may also be provided on the air duct docking structure 5, and 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 can be connected to the water supply device on the base station 200 (such as the base station clean water tank or the tap water pipe docking joint), so that the base station 200 can realize automatic water supply to the clean water tank on the cleaning device 100. 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. Moreover, the base station 200 can be provided with only a storage cavity for storing dirt, without the need to provide a base station clean water tank, which makes the structure simpler.

[0098] Example 2

[0099] In this embodiment, the reversing drive structure is a non-electric drive structure.

[0100] In one embodiment, the reversing drive structure can be a handle outside the extension device body 1, and the handle can be a knob structure. The air duct switching structure switches between the first connection state and the second connection state in response to the user's force on the handle.

[0101] In another example, the reversing drive structure may be a movable part, which may be a mechanical structure with a reciprocating motion state such as a connecting rod or a paddle. The movable part is arranged in the device body 1, or extends to the outside of the device body 1. When the cleaning device 100 is docked with the base station 200, the movable part abuts against the base station 200, and presents a first state under the action of the abutting force. In the first state, the air duct switching structure is driven to present a first connected state, so that the suction device 3 can act on the base station 200. When the cleaning device 100 is separated from the base station 200, the abutting force disappears, and the movable part is reset to the second state under the influence of the reset spring and / or its own gravity, and in the second state, the air duct switching structure is driven to present a second connected state, so that the suction device 3 can act on the dirt collecting chamber 2.

[0102] In this embodiment, the cleaning device is equipped with an air duct switching mechanism, allowing the suction device of the cleaning device to communicate with both the cleaning device's collection chamber and the base station. This allows both suction and discharge to be achieved with a single motor, greatly simplifying the structure of the cleaning system and reducing production costs. Furthermore, the air duct switching mechanism can be adjusted without electrical drive, offering the advantages of convenient operation and reduced costs.

[0103] Obviously, the embodiments described above are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, 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 this application.
