Further, as shown in fig. 1, the first frame 11 is provided with a rotatable rolling brush 16. The rolling brush 16 is rotated to clean the area to be cleaned, and the dust and solid garbage swept by the rolling brush 16 are sucked into the dust collecting box 13 by the suction force generated by the dust suction fan. Specifically, as shown in fig. 1, the first frame 11 is provided with drive wheels 18 and universal wheels 19 at intervals in the front-rear direction. The driving wheel 18 is used to drive the first frame 11 to move and change the traveling direction of the first frame 11. The universal wheels 19 are used to assist in supporting the first frame 11. The roller brush 16 is located between the drive wheel 18 and the universal wheel 19. The rolling brush 16 can rotate relative to the area to be cleaned when the first frame 11 moves in the area to be cleaned, so as to clean the area to be cleaned.

Further, a dust discharge port is provided at the bottom of the dust box 13. A cover plate for covering the dust discharge port is provided in the dust collecting box 13. The cover plate can rotate relative to the dust collecting box 13, and then the dust discharging opening is opened, so that the foreign matters 99 in the dust collecting box 13 can be transferred out from the dust collecting box 13 through the dust discharging opening.

Further, the cleaning member 15 is used to wipe the cleaning region. The cleaning element 15 can be, for example, a substantially rectangular mop which can be washed with water. Of course, the cleaning element 15 is not limited to a mop, but may be another material, such as a sponge, etc., which is not specified in this application. The cleaning member 15 is not limited to a rectangular shape, but may have other shapes, such as a triangular shape, and the like, and this is not limited to this. Further, as shown in fig. 2, the cleaning member 15 is disposed at the bottom of the first housing 11. The cleaning elements 15 are thus wiped clean the area to be cleaned under a certain ground pressure.

Further, as shown in fig. 2 and 7, the second frame 21 has a hollow structure as a whole, and the hollow portion forms an inner cavity. Further, the second chassis 21 includes a main body portion 23 and an extension portion 25 provided at one side of the main body portion 23. As shown in fig. 2, for example, the body portion 23 has a substantially rectangular parallelepiped shape. The extension portion 25 is located at one side of the main body portion 23. And the extension portion 25 has a slope 28 inclined toward the main body portion 23. Further, an inlet port 26 opened outward is provided in the second housing 21. The inlet port 26 communicates with the interior chamber. The access opening 26 is used for the passage of the cleaning robot so that the cleaning robot can enter the inner cavity of the second chassis 21. As shown in fig. 2, for example, the inlet 26 is provided on the right side of the main body 23. And the inlet port 26 is open toward the inclined surface 28 of the extension 25. So that the cleaning robot can enter the second chassis 21 through the entrance 26 through the inclined surface 28 of the extension 25.

Further, a parking portion 29 is further provided on the second frame 21. The rest portion 29 has an upwardly facing rest surface 31. The parking surface 31 is used for parking the cleaning robot. For example, as shown in fig. 2, the parking portion 29 is provided at a lower portion of the second frame 21. And the access opening 26 is opened toward the parking surface 31 so that the cleaning robot can be parked on the parking surface 31 through the access opening 26.

In the present embodiment, the second frame 21 is provided with a cleaning tank 33 for cleaning the cleaning material 15. Specifically, for example, as shown in fig. 2, the parking surface 31 is recessed downward to form a wash bowl 33 with an upward notch. That is, the notch of the wash bowl 33 is opened upward. And the cleaning robot can be stopped above the cleaning bath 33. In this way, on the one hand, when the cleaning robot is parked on the parking surface 31, the cleaning elements 15 on the first frame 11 can be placed in the cleaning tank 33; on the other hand, the cleaning robot is located above the cleaning tank 33, so that the space in the second frame 21 can be saved, and the operation is convenient. Further, a cleaning device is provided in the cleaning tank 33. The cleaning device comprises a rotatable cleaning working head 35 and a dirt scraping piece 37 arranged on the cleaning working head 35. The scraping member 37 is used to scrape the cleaning member 15. Specifically, the scraping member 37 may be a scraper or a wiper. When cleaning is required, first, the cleaning member 15 is placed in the cleaning bath 33. The wash head 35 is then rotated so that the scraping member 37 can scrape the surface of the cleaning member 15 that is in contact with the area to be cleaned.

Further, a clean water tank 39 is also provided on the second frame 21. For example, as shown in fig. 2, the parking portion 29 is located below the clean water tank 39. When the cleaning robot is thus parked on the parking part 29, the cleaning robot is located below the clean water tank 39. Thereby saving space within the second housing 21. Further, the clean water tank 39 is used for conveying clean water into the cleaning tank 33. The clean water is used for washing and cleaning stains on the surfaces of the working head 35, the dirt scraping part 37 and the cleaning part 15 and washing the stains into the cleaning groove 33.

Further, a clean water pipe 41 for communicating the clean water tank 39 and the cleaning tank 33 is provided on the second frame 21. The clean water pipe 41 is provided with a water supply pump 44. The water supply pump 44 is thus turned on, and fresh water can flow from the fresh water tank 39 into the wash bowl 33 through the fresh water pipe 41. Specifically, as shown in fig. 2, for example, a clean water pipe 41 is connected at an upper end thereof to the clean water tank 39 and at a lower end thereof to the wash bowl 33. Further, a clean water pipe 41 is located below the clean water tank 39. The clean water pipe 41 has a third opening 46 opened upward. The clean water tank 39 has a fourth opening 47 opened downward. The third opening 46 can be butted against the fourth opening 47 in the up-down direction. So that the clean water tank 39 can be taken out upwardly from the second housing 21 when the clean water in the clean water tank 39 is less and the addition of clean water is required, as shown in fig. 2. After adding clear water. The clean water tank 39 may be placed in the second housing 21 such that the fourth opening 47 of the clean water tank 39 is butted against the third opening 46 of the clean water pipe 41 in the up-and-down direction, thus simplifying the water exchange operation for the user.

Further, a first valve 49 for opening and closing the fourth opening 47 is provided in the clean water tank 39. For example, as shown in fig. 2, a first valve 49 is provided at the bottom of the clean water tank 39. The first valve 49 is used to control the outflow of fresh water from the fresh water tank 39. The first valve 49 can thus be closed before the clean water tank 39 is removed from the second housing 21, to prevent clean water from flowing out of the fourth opening 47. When the clean water tank 39 is connected to the clean water pipe 41, the first valve 49 may be opened to allow clean water to flow into the clean water pipe 41 from the fourth opening 47.

In the present embodiment, the second frame 21 is provided with a recovery device. The recovery device comprises at least one recovery tank 55. The at least one may be 1 or more. As shown in fig. 7, for example, the recovery device includes a recovery tank 55. As shown in fig. 3, for example, the recovery device includes two recovery tanks 55. Further, the recovery tank 55 is used to communicate with the cleaning tank 33 and/or the dust box 13, so that the recovery tank 55 can recover the sewage 98 in the cleaning tank 33 and/or the foreign matters 99 in the dust box 13. That is, as shown in fig. 7, the recovery tank 55 is used to communicate with the cleaning tank 33 and the dust box 13 so that the recovery tank 55 can recover the sewage 98 in the cleaning tank 33 and the foreign matter 99 in the dust box 13. Alternatively, as shown in fig. 3, the recovery box 55 is used to communicate with the cleaning tank 33 or the dust box 13, so that the recovery box 55 can recover the sewage 98 in the cleaning tank 33 or the foreign matters 99 in the dust box 13. In this way, the cleaning robot system according to the embodiment of the present invention can clean the mop by the cleaning tank 33 and recover the sewage 98 in the cleaning tank 33 by the recovery tank 55; and the dust collecting box 13 can be automatically collected by the recovery box 55.

Further, the parking portion 29 is located below the recovery tank 55, for example, as shown in fig. 2. When the cleaning robot is parked on the parking part 29, the cleaning robot is located below the recovery tank 55. Thereby saving space within the second housing 21.

Further, fig. 3 shows a first example of the master base station provided in the embodiment of the present application. This first embodiment is described in detail below with reference to fig. 3.

Specifically, in the present embodiment, the recovery device includes two recovery tanks 55 that are not communicated with each other. For example, as shown in fig. 3, the two recovery tanks 55 are a first tank 51 on the left side and a second tank 53 on the right side. Further, the two recovery tanks 55 are respectively communicated with the cleaning tank 33 and the dust box 13, so that the two recovery tanks 55 can respectively recover the sewage 98 and the foreign matters 99. For example, as shown in fig. 3, the first case 51 is used to communicate with the dust box 13 so that the first case 51 can collect the foreign materials 99. The second tank 53 is adapted to communicate with the wash tank 33 so that the second tank 53 can recover the sewage 98. In this way, since the first tank 51 and the second tank 53 are not communicated with each other, that is, the first tank 51 and the second tank 53 are independent from each other, the first tank 51 may recover the foreign matters 99 in parallel with the second tank 53 and recover the sewage 98, or may recover the foreign matters in sequence. That is, the first tank 51 recovers the foreign matter 99 while the second tank 53 recovers the sewage 98. Or the first tank 51 recovers the foreign matters 99 before or after the second tank 53 recovers the sewage 98.

Further, as shown in fig. 3, two recovery tanks 55 are provided above the parking portion 29. When the cleaning robot is thus parked on the parking section 29, the cleaning robot is located below the two recovery boxes 55. Thereby saving space within the second housing 21.

Further, two recovery pipelines are further arranged on the second frame 21. Specifically, the two recovery ducts are a first recovery duct 57 on the left side and a second recovery duct 59 on the right side, respectively. Further, two recovery pipes correspond to the two recovery tanks 55. The correspondence may be that the position of the recovery tank 55 coincides with the position of the recovery duct. For example, as shown in fig. 3, two recovery pipes are located below the two recovery tanks 55, respectively. Further, the recovery pipes communicate with the corresponding recovery tanks 55 so that the recovery tanks 55 can recover the sewage 98 in the cleaning tank 33 or the foreign matters 99 in the dust box 13 through the corresponding recovery pipes. Specifically, as shown in fig. 3, the first recycling duct 57 is communicated with the first box 51, so that the first box 51 can recycle the foreign matters 99 in the dust box 13 through the first recycling duct 57. The second recovery duct 59 is in communication with the second tank 53 so that the second tank 53 can recover the contaminated water 98 in the cleaning tank 33 through the second recovery duct 59.

Further, the recovery pipes are located below the corresponding recovery tanks 55. For example, as shown in fig. 4, the first recovery duct 57 is located below the first tank 51. The second recovery duct 59 is located below the second tank 53. Further, the recovery duct has a first opening 63 opened upward. As shown in fig. 4, for example, the upper ends of the first and

second recovery ducts

57 and 59 each have a first opening 63 opened upward. Further, the recovery tank 55 has a second open mouth 45 opened downward. For example, as shown in fig. 4, the bottom of each of the first and

second cases

51 and 53 has a second opening 45 opened downward. Further, the second opening 45 can be butted against the corresponding first opening 63 in the up-down direction. Specifically, as shown in fig. 4, the second opening 45 of the first casing 51 can be butted against the first opening 63 of the first recovery duct 57 in the up-down direction. Thus, when the first casing 51 contains a large amount of foreign matter 99, the first casing 51 can be taken out upward from the second housing 21. After the foreign matter 99 is removed. The first casing 51 may be placed in the second housing 21 such that the second opening 45 of the first casing 51 is butted against the first opening 63 of the first recovery duct 57 in the up-down direction, thus simplifying the operation of the user for removing the foreign matter 99 in the first casing 51. As shown in fig. 4, the second opening 45 of the second casing 53 can be butted against the first opening 63 of the second recovery duct 59 in the up-down direction. Thus, when the amount of the contaminated water 98 in the second tank 53 is large, the second tank 53 can be taken out upward from the second frame 21. After the sewage 98 is removed. The second casing 53 may be placed in the second housing 21 such that the second opening 45 of the second casing 53 is butted against the first opening 63 of the second recovery duct 59 in the up-down direction, thus simplifying the operation of removing the contaminated water 98 in the second casing 53 by the user.

Further, the centers of gravity of the clean water tank 39 and the recovery tank 55 are on a straight line. Specifically, in the present embodiment, the recovery tank 55 is two. The centers of gravity of the three tanks 39 and 55 are aligned. For example, as shown in fig. 5, the clear water tank 39 and the two recovery tanks 55 are arranged in parallel with each other in a straight line extending in the left-right direction. As shown in fig. 6, the clear water tank 39 and the two recovery tanks 55 are arranged in parallel with each other along a straight line extending in the left-right direction between the clear water tank 39 and the one recovery tank 55. Thus, when a user needs to take out or put in the clean water tank 39 and/or the recovery tank 55 from or to the second frame 21, the clean water tank 39 and/or the recovery tank 55 are arranged in a manner that is convenient for the user to take and put in.

In the present embodiment, the second frame 21 is provided with an access opening 101 which is open upward, and the clean water tank 39 and the recovery tank 55 can be taken out or put in through the access opening 101. Thus, when a user needs to take out or put in the clean water tank 39, the first box 51 and the second box 53 from or to the second frame 21, the clean water tank 39 and the two recycling tanks 55 are arranged in a manner that facilitates the user's taking and putting operations without increasing the space volume of the second frame 21. Specifically, as shown in fig. 4, an access opening 101 opened upward is provided in the top wall of the second frame 21, and at least one of the clean water tank 39 and the recovery tank 55 faces the access opening 101. More specifically, as shown in fig. 4, the clean water tank 39 faces the access opening 101. Therefore, the clean water tank 39 and the recovery tank 55 on the second frame 21 can be taken out upwards or put in downwards through the access opening 101, and the access opening 101 is convenient for a user to take and put operations and does not increase the space volume of the second frame 21. Further, the clear water tank 39 and the recovery tank 55 are at least partially overlapped with each other in the height direction of the second frame 21.

As shown in fig. 3 and 4, the second frame 21 is rotatably provided with a cover 30. The cover 30 is used to open and close the access opening 101. For example, as shown in fig. 3, the cover 30 closes the access opening 101, and the clean water tank 39 cannot be taken out upward through the access opening 101. For example, as shown in fig. 4, the cover 30 opens the access opening 101, and the clean water tank 39 is taken out upward through the access opening 101.

Further, the second frame 21 is provided with an airflow generator 43 and a power mechanism 69 which are respectively connected with the two recycling boxes 55. For example, as shown in fig. 3, the airflow generator 43 is disposed on the upper left side of the main body portion 23. The power mechanism 69 is disposed on the second recovery duct 59. Further, the airflow generator 43 is used for generating the suction force of the airflow into the recovery tank 55 so as to suck the foreign matters 99 into the recovery tank 55; the power mechanism 69 is used to allow the sewage 98 to enter the recovery tank 55. In particular, the airflow generator 43 may be a first fan. The power mechanism 69 may be a suction pump.

Further, a second valve 71 for opening and closing the second opening 45 is provided in the first tank 51. For example, as shown in fig. 3, the second valve 71 is disposed at the bottom of the first tank 51. The second valve 71 controls the outflow of the foreign matter 99 in the first tank 51. So that the second valve 71 can be closed before the first container 51 is taken out of the second frame 21 to prevent the foreign matter 99 from flowing out of the second opening 45. When the first tank 51 is connected to the first recovery pipe 57, the second valve 71 may be opened to allow the foreign substances 99 to flow into the first tank 51 from the second opening 45.

Further, a third valve 73 for opening and closing the second opening 45 is provided in the second tank 53. For example, as shown in fig. 3, the third valve 73 is provided at the bottom of the second tank 53. The third valve 73 is used to control the outflow of the contaminated water 98 in the second tank 53. So that the third valve 73 can be closed before the second casing 53 is taken out of the second frame 21 to prevent the sewage 98 from flowing out of the second opening 45. When the second tank 53 is connected to the second recovery pipe 59, the third valve 73 may be opened to allow the contaminated water 98 to flow into the second tank 53 from the second open port 45.

Further, the second frame 21 is provided with a dust collecting box 13 for communicating with; and the foreign matter 99 is collected into the opening in the collection box 55. The opening is provided on the resting surface, as shown in fig. 3, for example. And the opening communicates with the lower end of the first recovery pipe 57. Further, the opening is opened upward so that the cleaning robot can be parked above the cleaning bath 33. Specifically, when the cleaning robot is parked on the parking surface, the opening communicates with the dust box 13 of the cleaning robot, so that the foreign substances 99 in the dust box 13 can enter the first recovery duct 57 through the opening and finally enter the first container body 51. So on the one hand, when the cleaning robot is parked on the parking surface 31, the dust collecting box 13 on the first frame 11 can be communicated with the opening; on the other hand, the space in the second frame 21 can be saved, and the operation is convenient.

Further, fig. 7 shows a second example of the master base station provided in the embodiment of the present application. This second embodiment is described in detail below with reference to fig. 7.

Specifically, in the present embodiment, the recovery means includes one recovery tank 55 and a three-way valve 75 communicating with the recovery tank 55. The three-way valve 75 is used to communicate the recovery tank 55 with the cleaning tank 33 and the dust box 13 by turns, so that the recovery tank 55 can recover the sewage 98 and the foreign matters 99 by turns. That is, the recovery box 55 is used for recovering the sewage 98 in the cleaning tank 33 and the foreign matters 99 in the dust box 13. In particular, the second housing 21 is provided with an airflow generator 43 connected to the recovery tank 55. For example, as shown in fig. 7, the airflow generator 43 is disposed on the upper left side of the main body portion 23. And the airflow generator 43 is in communication with the recovery tank 55. Further, the airflow generator 43 is used to generate an airflow suction force into the recovery tank 55 so as to suck the foreign matters 99 and the contaminated water 98 into the recovery tank 55. In particular, the airflow generator 43 may be a second fan.

Further, in order to ensure the efficiency of the air flow generator 43 in sucking the contaminated water 98 and the foreign matters 99, the air flow generator 43 cannot suck the foreign matters 99 in the dust box 13 and the contaminated water 98 in the cleaning tank 33 in parallel, but should suck them one after another. That is, the recovery tank 55 alternately recovers the foreign matters 99 and the contaminated water 98.

Further, the three-way valve 75 includes a valve body and a spool provided in the valve body. The valve body has a first flow passage 83, a second flow passage 85, and a third flow passage 87. As shown in fig. 8 and 9, for example, the valve body includes a first extension 77, a second extension 79, and a third extension 81 that extend vertically. The first extension 77 is located between the second extension 79 and the third extension 81. The second extension 79 is located to the right of the third extension 81. The first flow channel 83, the second flow channel 85, and the third flow channel 87 are disposed in the first extension 77, the second extension 79, and the third extension 81, respectively. Further, the valve body has a circular arc-shaped connecting pipe 89. The valve body has a first operating state in which the first flow passage 83 and the second flow passage 85 are communicated through the connection pipe 89, and a second operating state in which the first flow passage 83 and the third flow passage 87 are communicated through the connection pipe 89. For example, as shown in fig. 8, the spool is in a first operating state. The first flow passage 83 communicates with the second flow passage 85 via a connection pipe 89 having a circular arc shape. Therefore, the airflow generated by the airflow generator 43 has almost no energy loss when circulating in the first flow passage 83 and the second flow passage 85, so as to ensure smooth operation of the airflow and improve the efficiency of the recovery box 55 for recovering the foreign matters 99. As shown in fig. 9, the spool is in the second operating state. The first flow passage 83 communicates with the third flow passage 87 through a connection pipe 89 having a circular arc shape. Therefore, when the airflow generated by the airflow generator 43 circulates in the first flow channel 83 and the third flow channel 87, almost no energy loss exists, so that the smooth operation of the airflow is ensured, and the efficiency of recycling the sewage 98 of the recycling tank 55 is improved.

Further, the upper end of the first extension 77 is adapted to communicate with the recovery tank 55. The left end of the third extension section 81 is used for communicating with the cleaning tank 33. The right end of the second extension 79 is for communication with the dust box 13. Thus, when the valve core is in the first working state, the recovery tank 55 can be communicated with the dust collection box 13 through the three-way valve 75, and the recovery tank 55 can recover the foreign matters 99 in the dust collection box 13. When the valve core is in the second working state, the recovery tank 55 can be communicated with the cleaning tank 33 through the three-way valve 75, and the recovery tank 55 can recover the sewage 98 in the cleaning tank 33. That is, the recovery tank 55 alternately recovers the foreign matters 99 and the sewage 98 by the three-way valve 75.

Further, two recovery pipelines are further arranged on the second frame 21. As shown in fig. 7, for example, the two recovery ducts are a first recovery duct 57 on the left side and a second recovery duct 59 on the right side, respectively. Further, one ends of the two recovery ducts are respectively used for communicating with the dust box 13 and the cleaning tank 33. For example, as shown in fig. 7, the lower end of the first recovery duct 57 communicates with the dust box 13. The lower end of the second recovery duct 59 communicates with the cleaning tank 33. Further, the other ends of the two recovery pipes are used for being respectively communicated with the second flow passage 85 and the third flow passage 87; so that the first flow passage 83 can alternately recover the sewage 98 in the cleaning tank 33 and the foreign matters 99 in the dust box 13. For example, as shown in fig. 7, the upper end of the first recovery duct 57 is adapted to communicate with the second flow path 85. The upper end of the second recovery conduit 59 is adapted to communicate with the third flow passage 87.

Further, the three-way valve 75 is located below the recovery tank 55. As shown in fig. 8 and 9, the first flow passage 83 has a first connection port 91 that opens upward. The recovery tank 55 has a second connection port 93 that opens downward. For example, as shown in fig. 7, the bottom of the recovery tank 55 has a second connection port 93 that opens downward. Further, the second connection port 93 is capable of being butted against the first connection port 91 in the up-down direction. Thus, when the amount of foreign matter 99 and/or contaminated water 98 in the recovery tank 55 is large, the recovery tank 55 can be taken out upward from the second housing 21. After the foreign substances 99 and/or the contaminated water 98 are removed, the recovery tank 55 may be put into the second housing 21 such that the second connection port 93 of the recovery tank 55 is in up-down abutment with the first connection port 91 of the first flow path 83, thus simplifying the user's operation of removing the foreign substances 99 and/or the contaminated water 98 from the recovery tank 55.

Further, the centers of gravity of the clean water tank 39 and the recovery tank 55 are on a straight line. Specifically, in the present embodiment, the number of the recovery tanks 55 is 1. So that the centers of gravity of both the clean water tank 39 and the 1 recovery tank 55 are on a straight line. For example, as shown in fig. 7, the clean water tank 39 and the recovery tank 55 are arranged in parallel with each other in a straight line extending in the left-right direction. Thus, when a user needs to take out or put in the clean water tank 39 and/or the recovery tank 55 from or to the second frame 21, the clean water tank 39 and/or the recovery tank 55 are arranged in a manner that is convenient for the user to take and put in.

In the present embodiment, the second frame 21 is provided with an access opening 101 which is open upward, and the clean water tank 39 and the recovery tank 55 can be taken out or put in through the access opening 101. Thus, when a user needs to take out or put in the clean water tank 39, the first box 51 and the second box 53 from or to the second frame 21, the clean water tank 39 and the two recycling tanks 55 are arranged in a manner that facilitates the user's taking and putting operations without increasing the space volume of the second frame 21. Specifically, the top wall of the second frame 21 is provided with an access opening 101 which is open upward, and at least one of the clean water tank 39 and the recovery tank 55 faces the access opening 101. Therefore, the clean water tank 39 and the recovery tank 55 on the second frame 21 can be taken out upwards or put in downwards through the access opening 101, and the access opening 101 is convenient for a user to take and put operations and does not increase the space volume of the second frame 21. Further, there is a partial overlap between the clean water tank 39 and the recovery tank 55 in the height direction of the second frame 21.

Further, as shown in fig. 7, a cover 30 is rotatably provided on the second frame 21. The cover 30 is used to open and close the access opening 101. For example, as shown in fig. 7, the cover 30 closes the access opening 101, and the clean water tank 39 cannot be taken out upward through the access opening 101.

Further, the second frame 21 is provided with a dust collecting box 13 for communicating with; and the foreign matter 99 is collected into the opening in the collection box 55. The opening is provided on the resting surface, as shown in fig. 7, for example. And the opening communicates with the lower end of the first recovery pipe 57. Further, the opening is opened upward so that the cleaning robot can be parked above the cleaning bath 33. Specifically, when the cleaning robot is parked on the parking surface, the opening communicates with the dust box 13 of the cleaning robot, so that the foreign substances 99 in the dust box 13 can enter the first recovery duct 57 through the opening and finally enter the first container body 51. So on the one hand, when the cleaning robot is parked on the parking surface 31, the dust collecting box 13 on the first frame 11 can be communicated with the opening; on the other hand, the space in the second frame 21 can be saved, and the operation is convenient.

Further, as shown in fig. 7, 1 recovery tank 55 is provided above the parking portion 29. When the cleaning robot is parked on the parking section 29 in this way, the cleaning robot is located below 1 recycle bin 55. Thereby saving space within the second housing 21.

Further, a separation device 27 is provided in the recovery tank 55. The separating apparatus 27 is located downstream of the airflow generator 43 in the direction of flow of the airflow. For example, as shown in fig. 7, the separator 27 is located within the recovery tank 55. The airflow generator 43 is located outside the recovery tank 55. The air flow moves from bottom to top through the recovery tank 55 toward the outside of the recovery tank 55. Further, the separation device 27 serves to separate gas from the sewage 98 and the foreign matter 99. In particular, the separation device 27 may be a water gas separation device 27. The water-gas separator 27 operates on the principle that a mixture of air, water and solids collides with a flow barrier provided in a flow passage of the separator, the moving speed of the mixture of air, water and solids after collision varies due to the difference in the mass of the mixture, and the separated water and solids are retained in the recovery tank 55, and the gas flows toward the outside of the recovery tank 55.

Further, a safety shut-off valve 97 is provided in the recovery tank 55. As shown in fig. 7, for example, a safety shut-off valve 97 is provided above the separator 27. The safety shut-off valve 97 is adapted to send a control signal after a predetermined amount of waste water 98 is reached, so that the air flow generator 43 can be shut off in response to the control signal. Specifically, in order to prevent the filter from being contaminated by the excessive amount of the sewage 98 in the recovery tank 55, a safety shut-off valve 97 is further provided in the recovery tank 55. So that a control signal can be sent after the predetermined amount of sewage 98 is reached; and the airflow generator 43 is closed, so that the airflow generator 43 is prevented from sucking the dust collection box 13 and the cleaning tank 33. More specifically, the safety cut-off valve 97 may be a float valve. When the sewage 98 amount reaches a certain height, the float valve floats upwards under the action of buoyancy to block the gas path, and the sensor is triggered to send out a control signal. Of course, the safety cut-off valve 97 is not limited to a float valve, and may be a float sensor. When the sewage 98 amount reaches a certain height, the float sensor floats up to a stop position under the action of buoyancy and sends a control signal.

Further, still include: and a controller electrically connected to the safety cut-off valve 97. The controller is adapted to receive the control signal and to control the closing of the airflow generator 43 in dependence on the control signal.
