Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning base station. Background Art

[0002] Cleaning robots are used to remove dust, trash, and stains from floors, glass, or walls. They include autonomous cleaning devices such as sweeping robots, window cleaning robots, floor scrubbers, and sweeper-mop robots. These robots, such as sweeping robots and sweeper-mop robots, have a mop or cleaning roller on their bottoms for cleaning the floor. The mop needs to be cleaned after cleaning.

[0003] After cleaning, the cleaning robot automatically enters the accompanying cleaning base station, where it automatically cleans the mop and wiper. The cleaning base station has a cleaning tray that collects dirt generated during cleaning of the mop and wiper. This easily leaves dirt on the cleaning tray. Related art uses water spray holes on the cleaning tray to spray water into the cleaning tray for cleaning. However, the water spray holes are fixed in position and have a limited spray range, requiring more water spray holes and a larger amount of water for cleaning. Utility Model Content

[0007] The cleaning base station further includes a driving structure disposed on the base station base, and the driving structure is configured to drive at least one of the nozzles to rotate so as to spray water into the cleaning tray.

[0010] In some embodiments, the water spraying structure is disposed above the cleaning tray, and the driving structure drives the water spraying port of the nozzle to rotate along a circular trajectory.

[0011] In some embodiments, the cleaning disc is provided with the drain trough between both ends in the length direction thereof;

[0013] In some embodiments, the water jet drive structure includes a mounting seat provided on the base of the base station, and a spherical cavity is formed on the mounting seat;

[0014] The nozzle is arranged obliquely in the vertical direction relative to the cleaning base station, and the nozzle is provided with a ball head accommodated in the spherical cavity;

[0015] The driving structure also includes a driving member and a circular ring member. One end of the nozzle in its extension direction is passed through the center hole of the circular ring member and is connected to the circular ring member. The other end has a water outlet.

[0020] In some embodiments, a sealing strip is provided on the edge of the cleaning tray, and the sealing strip is pressed against the cavity wall of the base station cavity.

[0021] The technical solution provided by the embodiments of the present application has the following advantages compared with the prior art:

[0022] 1. This cleaning base station comprises a cleaning tray, an extraction structure, and a water spraying structure. The cleaning tray is disposed within the base station cavity and has a drainage trough. The extraction structure is used to extract dirt from the drainage trough. The water spraying structure is movably disposed on the base station base, capable of spraying water into the cleaning tray and forming a water spraying trajectory within the cleaning tray. This can increase the cleaning range of the cleaning tray, reduce water consumption, and reduce or even eliminate blind spots in the cleaning process, thereby improving cleaning effectiveness. Furthermore, the movable water spraying structure enables a relatively small number of water spraying structures to complete a wide cleaning range, thereby reducing costs and space usage, and facilitating a miniaturized design of the cleaning base station.

[0055] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0057] like Figures 1 to 5 As shown, an embodiment of the present application provides a cleaning base station, which includes a base station base 1, a cleaning tray 2 and a sewage extraction structure. The base station base 1 has a base station cavity 100 for the cleaning robot to enter, and the cleaning tray 2 is arranged in the base station cavity 100. The cleaning tray 2 has a sewage trough 21, and the sewage extraction structure is arranged on the base station base 1 for extracting dirt in the sewage trough 21.

[0058] The cleaning base station further comprises a water spraying structure 3 , which is movably arranged on the base station base 1 . The water spraying structure 3 can spray water into the cleaning tray 2 and form a water spraying movement track in the cleaning tray 2 to clean the cleaning tray 2 .

[0059] It should be noted that the water spray structure 3 is movably arranged on the base station base 1, which means that the water spray structure 3 can be moved relative to the cleaning disc 2, so that the water flow sprayed by the water spray structure 3 forms a specific trajectory on the cleaning disc 2 as the water spray structure 3 moves, thereby increasing the cleaning range. In this way, the water flow sprayed by the water spray structure 3 can flush the cleaning disc 2, which is conducive to allowing dirt to quickly enter the sewage trough 21, rather than only spraying water to a specific position of the cleaning disc 2.

[0060] The water spray structure 3 can move in a linear manner, rotate about an axis, or move in an arc, etc. For example, when the water spray structure 3 moves in a linear manner, the water spray structure 3 can reciprocate along a straight line parallel to the width of the washing tray 2, along a straight line parallel to the length of the washing tray 2, or along a straight line parallel to any diagonal line of the washing tray 2 to spray water into the washing tray 2.

[0061] In addition, the water spraying structure 3 sprays water into the cleaning plate 2 so that the dirt enters the drain tank 21 in two ways. One is that the water flow sprayed by the water spraying structure 3 drives the dirt on the cleaning plate 2 into the drain tank 21 during the flow to the drain tank 21, such as referring to Figure 1 In this case, the water spray structure 3 can be located above the washing tray 2, spraying water downwardly, and the speed of the water flow sprayed by the water spray structure 3 can be relatively low. Another option is that the water flow sprayed by the water spray structure 3 can directly push the dirt on the washing tray 2 into the sewage trough 21. For example, in this case, the water spray structure 3 is located on one side of the washing tray 2 in the longitudinal direction, and can spray water to the other side of the washing tray 2 in the longitudinal direction. The speed of the water flow sprayed by the water spray structure 3 can be relatively high.

[0062] It is understandable that by providing a water spray structure 3, the water spray structure 3 is movably provided on the base station base 1, and can spray water into the cleaning tray 2 and form a water spraying trajectory in the cleaning tray 2 to clean the cleaning tray 2. This can increase the cleaning range of the cleaning tray 2, reduce water consumption, and reduce or even avoid the existence of cleaning dead corners, thereby improving the cleaning effect. In addition, the movably provided water spray structure 3 can enable the water spray structure 3 to complete a large range of cleaning with a small number of water spray structures 3, thereby reducing costs and space occupation, and facilitating the miniaturization design of the cleaning base station. When the flow rate of the water sprayed by the water spray structure 3 is high, the water flow can push dirt into the drain trough 21, thereby improving the cleaning effect of the cleaning tray 2.

[0063] In addition, by setting up a water spray structure 3, the water spray structure 3 can be controlled by the controller of the cleaning base station to clean the cleaning disc 2 after the cleaning robot exits the base station cavity 100. In this way, the dirt in a wet state can be cleaned in time to avoid the dirt sticking to the cleaning disc 2 after drying, thereby increasing the difficulty of cleaning the cleaning disc 2.

[0064] The water spray structure 3 can be configured to include a nozzle 31, a water pump (not shown), and a water supply pipe 9 connected to the water pump. The water supply pipe 9 is connected to the nozzle 31. The water pump can draw clean water from the clean water tank and transport it to the nozzle 31 through the water supply pipe 9 for spraying, thereby cleaning the cleaning disc 2. The water pump can also be replaced with a magnetic pump, a pneumatic diaphragm pump, a centrifugal pump, etc. Of course, a pipeline connected to the cleaning liquid tank (not shown) of the cleaning base station can also be connected to the water supply pipe 9, so that water containing cleaning liquid can be sprayed into the cleaning disc 2 to clean the cleaning disc 2.

[0065] In some embodiments, reference Figure 2 and Figure 3 A door body 5 is provided on the base station base 1 , and the door body 5 is slidably provided on the base station base 1 in the up and down directions of the cleaning base station. The door body 5 can close the opening of the base station cavity 100 .

[0066] It can be understood that by setting up the door body 5, when the water spraying structure 3 sprays water into the cleaning tray 2 to clean the cleaning tray 2, the opening of the base station cavity 100 can be closed by the door body 5, so as to prevent the water from splashing out of the opening of the base station cavity 100 to the outside of the base station cavity 100 when the water spraying structure 3 sprays water into the cleaning tray 2.

[0067] The door body 5 is driven by the driving assembly 6 to enable the door body 5 to slide in the up and down directions of the cleaning base station.

[0068] For example, in a specific implementation, referring to Figure 3 The drive assembly 6 can be selected to be a motor 61, a transmission gear 62 and a rack 63. The motor 61 is fixed to the base station base 1, the transmission gear 62 is connected to the output shaft of the motor 61, and the rack 63 is arranged along the vertical direction of the cleaning base station and fixed to the door body 5. The transmission gear 62 and the rack 63 are meshed. In this way, the motor 61 drives the transmission gear 62 to rotate and drives the rack 63 to move in the vertical direction of the cleaning base station, thereby realizing the sliding of the door body 5 in the vertical direction of the cleaning base station to open or close the opening of the base station cavity 100. Of course, the above-mentioned drive assembly can also be selected as a structure such as an electric push rod, a cylinder, etc. that can drive the door body to move linearly.

[0069] The rack 63 can be provided separately from the door body 5 and fixed on the door body 5. The rack 63 can also be provided integrally with the door body 5.

[0070] For example, in a specific implementation, referring to Figure 4 A door body groove 22 is provided on the cleaning disc 2, and the door body groove 22 is used to accommodate the lower end of the door body 5 in the up and down direction of the cleaning base station.

[0071] It is understandable that by providing the door body groove 22, not only can the door body 5 be positioned and limited when the door body 5 closes the opening of the base station cavity 100, but the door body groove 22 and the door body 5 can also cooperate to prevent the water in the cleaning tray 2 from being flushed into the water spray structure 3 and flowing out through the lower end of the door body 5, thereby improving the sealing performance. In addition, considering that the cleaning tray 2 can be detachably mounted on the base station base 1, when the cleaning tray 2 is removed for cleaning after the cleaning base station has been working for a period of time, the door body groove 22 can also be cleaned to prevent a lot of dust from accumulating in the door body groove 22.

[0072] In addition, in order to improve the sealing performance of the door body 5, sealing strips can be provided on the lower side, left side and right side of the door body 5. The sealing strips located on the left and right sides of the door body 5 are placed on the cavity wall of the base station cavity 100, and the sealing strip located on the lower side of the door body 5 can be pressed between the door body 5 and the bottom wall of the door body groove 22, thereby improving the sealing performance of the door body 5 when closing the opening of the base station cavity 100.

[0073] Of course, in another specific implementation, the above-mentioned door groove can also be set on the base station base.

[0074] In some embodiments, reference Figure 4 A sealing strip 8 is provided on the edge of the cleaning disk 2 , and the sealing strip 8 is pressed against the cavity wall of the base station cavity 100 .

[0075] It can be understood that by setting the sealing strip 8, after the cleaning tray 2 is placed in the base station cavity 100, the sealing strip 8 can seal the gap between the cleaning tray 2 and the cavity wall of the base station cavity 100, thereby preventing water from splashing into the interior of the cleaning base station when the water spraying structure 3 sprays water into the cleaning tray 2.

[0076] It should be noted that, in this case, the cleaning tray 2 can be detachably placed in the base station cavity 100 , so that the cleaning tray 2 can be taken out for cleaning after being used for a period of time, thereby avoiding stubborn dirt remaining in the cleaning tray 2 .

[0077] The base station base may also be provided with a setting platform in the base station cavity, and the edge of the cleaning plate is set on the setting platform, and the sealing strip is set on the setting platform to achieve sealing.

[0078] In some embodiments, reference Figure 5 The water spray structure 3 includes at least one nozzle 31, one end of which passes through the cavity wall of the base station cavity 100 and extends into the base station cavity 100. A sealing member 7 is provided on the nozzle 31 to seal the gap between the nozzle 31 and the cavity wall of the base station cavity 100.

[0079] It can be understood that by setting the sealing member 7, the gap between the nozzle 31 and the cavity wall of the base station cavity 100 can be sealed to prevent water vapor and water sprayed from the nozzle 31 from splashing into other parts of the base station base 1, especially to prevent water from splashing into the cavity where the electronic control components are installed on the base station base 1 and causing a short circuit.

[0080] For example, in a specific implementation, the nozzle 31 can swing to spray water onto the cleaning tray 2. In this case, the sealing member 7 can be a rubber sleeve that is mounted on the nozzle 31 and can swing with the nozzle 31 to ensure a sealing effect. Of course, if the nozzle is fixed to the base of the base station, the sealing member can also be a sealing ring or formed by curing a sealant.

[0081] For example, in a specific implementation, two water spray structures 3 are provided, and the two water spray structures 3 are respectively located on both sides of the cleaning tray 2 in the length or width direction. In this case, each water spray structure 3 includes a nozzle 31.

[0082] In some embodiments, reference Figures 6 to 13 The water spraying structure 3 includes at least one nozzle 31 . The cleaning base station further includes a driving structure 4 disposed on the base station base 1 , and the driving structure 4 drives the at least one nozzle 31 to rotate so as to spray water into the cleaning tray 2 .

[0083] It is understandable that each driving structure 4 may drive one nozzle 31 to rotate, or each driving structure 4 may drive multiple nozzles 31 to rotate synchronously.

[0084] Further, refer to Figures 6 to 9 The water spraying structure 3 is arranged above the cleaning plate 2, and the driving structure 4 drives the water spraying port of the nozzle 31 to rotate along a circular trajectory.

[0085] It can be understood that the water spray structure 3 is arranged above the cleaning disc 2, so that the nozzle 31 sprays water into the cleaning disc 2 below to clean the cleaning disc 2, and the nozzle 31 is driven by the driving structure 4 to rotate the water spray port along a circular trajectory, which can increase the coverage range of the water flow sprayed by the nozzle 31, thereby increasing the cleaning range of the cleaning disc 2, so that the dirt in the cleaning disc 2 can enter the drain trough 21 driven by the water flow and be extracted by the sewage extraction structure, thereby improving the cleaning effect of the cleaning disc 2.

[0086] It should be noted that the plane where the circular trajectory is located can be a plane inclined relative to the horizontal plane, such as Figure 7 As shown, the angle of inclination can be reasonably set according to actual needs so that the nozzle 31 can spray water toward the cleaning dish 2. Alternatively, the plane where the circular trajectory is located can also be a horizontal plane.

[0087] For example, in a specific implementation, referring to Figures 6 to 8 There are two water spray structures 3, which are respectively located on both sides of the cleaning disc 2 in the length direction. A sewage trough 21 is provided between the two ends of the cleaning disc 2 in the length direction.

[0088] Understandably, in this manner, the two water spray structures 3 can respectively rinse the areas of the cleaning pan 2 on both sides of the drain trough 21 along its own length direction, and the coverage areas of the nozzles 31 of the two water spray structures 3 can partially overlap, thereby improving the cleaning effect of the cleaning pan 2 and minimizing blind spots in the cleaning process. Of course, the number of the above-mentioned water spray structures 3 can be reasonably set to one, three, or more according to actual needs.

[0089] Specifically, refer to Figure 9 The sidewall of the cleaning pan 2 includes a first groove side surface 201 and two arcuate second groove side surfaces 202. The first groove side surface 201 extends along the length of the cleaning pan 2. The two second groove side surfaces 202 are located on either side of the drainage trough 21 in the length direction of the cleaning pan 2. The drainage trough 21 is located on one side in the width direction of the cleaning pan 2. The second groove side surfaces 202 are configured to guide water into the drainage trough 21.

[0090] It is understood that by providing the curved second groove side surface 202, the water flow sprayed into the cleaning pan 2 by the nozzle 31 can be directed so that the water flow enters the drainage trough 21, thereby carrying the dirt on the cleaning pan 2 into the drainage trough 21 and being extracted by the sewage extraction mechanism. In this case, when the nozzle 31 rotates, it rotates along the second groove side surface 202 and in a direction close to the drainage trough 21, so that the water flow enters the drainage trough 21 and carries the dirt into the drainage trough 21.

[0091] For example, referring to Figure 9 The above-mentioned sewage trough 21 may be provided with a sewage outlet 211, and the sewage outlet 211 is connected to the sewage extraction structure. For example, a silencer cavity (not shown in the figure) connected to the sewage outlet 211 is provided on the base of the base station, and the cleaning base station also includes a sewage tank (not shown in the figure) provided on the base of the base station. The sewage tank is connected to the silencer cavity through a sewage extraction pipe. The sewage extraction structure can vacuum the sewage tank so that the dirt enters the sewage tank through the sewage outlet 211, the silencer cavity and the sewage extraction pipe. Among them, the sewage extraction structure can be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc. to achieve vacuuming of the sewage tank. Of course, the above-mentioned sewage trough may also not be provided with a sewage outlet, but the sewage extraction pipe connected to the sewage tank directly extends into the sewage trough, and the dirt in the sewage trough can also be extracted.

[0092] For example, in a specific implementation, referring to Figures 10 to 13The driving structure 4 includes a mounting seat 43 provided on the base station base 1, and a spherical cavity 431 is formed on the mounting seat 43. The nozzle 31 is tilted relative to the vertical direction of the cleaning base station, and a ball head 311 is provided on the nozzle 31 to be accommodated in the spherical cavity 431.

[0093] The above-mentioned driving structure 4 also includes a driving member 41 and a circular ring member 42. One end of the nozzle 31 in its extension direction is passed through the center hole of the circular ring member 42, and the end is connected to the circular ring member 42. The other end has a water outlet. The driving member 41 can drive the circular ring member 42 to rotate around its own central axis to drive the nozzle 31 to rotate relative to the mounting seat 43.

[0094] It can be understood that the driving member 41 drives the annular member 42 to rotate around its own central axis, and the nozzle 31 is connected to the annular member 42. Then, one end of the nozzle 31 connected to the annular member 42 rotates around the central axis of the annular member 42 under the drive of the annular member 42. Since the ball head 311 on the nozzle 31 is accommodated in the spherical cavity 431 of the mounting seat 43, the ball head 311 rolls in the spherical cavity 431, so that the end of the nozzle 31 with the water outlet rotates along a circular trajectory. This not only allows the nozzle 31 to rotate to spray water to increase the coverage range, but also facilitates the water supply pipe 9 connected to the end of the nozzle 31 away from the water outlet to not be entangled due to the rotation of the nozzle 31, thereby avoiding the situation where the water supply pipe 9 is squeezed due to entanglement and cannot supply water.

[0095] In addition, in this case, each nozzle 31 is correspondingly provided with a driving member 41, a circular member 42 and a mounting seat 43. Therefore, it is preferred that each water spraying structure 3 includes a nozzle 31, but the number of water spraying structures 3 can be one or more.

[0096] It should be noted that whether the circular paths formed by the end of the nozzle 31 connected to the annular member 42 and the end with the water spout are the same or different in size depends on the position of the ball head 311 in the direction of extension of the nozzle 31. If the ball head 311 is located in the middle of the direction of extension of the nozzle 31, the circular paths formed by the rotation of the two ends of the nozzle 31 are the same in size. If the ball head is relatively close to one end of the nozzle 31 in the direction of extension, the circular paths formed by the rotation of the two ends of the nozzle 31 are different in size.

[0097] For example, referring to Figure 10When the driving member 41 drives the annular member 42 to rotate forward, the end of the nozzle 31 with the water outlet rotates counterclockwise, and the water jetted from the nozzle 31 moves counterclockwise within the cleaning dish 2. When the driving member 41 drives the annular member 42 to rotate backward, the end of the nozzle 31 with the water outlet rotates clockwise, and the water jetted from the nozzle 31 moves clockwise within the cleaning dish 2. The directions of the annular member 42 in forward and reverse rotation are opposite. For example, if the annular member 42 rotates counterclockwise during forward rotation, it will rotate clockwise during reverse rotation, or if the annular member 42 rotates clockwise during forward rotation, it will rotate counterclockwise during reverse rotation.

[0098] For example, referring to Figures 10 to 13 The above-mentioned annular member 42 can be selected as a face gear, and the driving member 41 drives the face gear to rotate through the transmission member 44. Among them, the driving member 41 can be selected as a motor, and the transmission member 44 can be selected as a gear. The motor drives the face gear to rotate around its own central axis through the gear meshing with the face gear, thereby driving the nozzle 31. Alternatively, the above-mentioned annular member can also be selected as a bevel gear, and the driving member can be selected as a motor. The motor drives the annular member through another bevel gear meshing with the annular member. Alternatively, the rotation of the above-mentioned annular member can also be achieved through a transmission member, and the transmission member is driven by the driving member. For example, the transmission member is a transmission belt wound around the annular member, and the driving member can drive the transmission belt to drive the annular member to rotate. The driving member can be selected as a motor, and the motor drives the transmission belt to rotate through a driving wheel.

[0099] Furthermore, the mounting seat 43 may be composed of two detachably connected parts, each part being provided with a hemispherical cavity. After the two parts are connected, the two hemispherical cavities form a spherical cavity 431 , which facilitates the installation and removal of the nozzle 31 .

[0100] For example, referring to Figure 10 and Figure 11 The central axis of the annular member 42 is tilted relative to the vertical direction of the cleaning base station, so that the plane where the circular trajectory formed by the end of the nozzle 31 with the water outlet is located is tilted relative to the horizontal plane, which can further increase the coverage of the nozzle 31. Of course, the central axis of the annular member can also be set to extend along the vertical direction of the cleaning base station, so that the plane where the circular trajectory formed by the end of the nozzle with the water outlet is located is a horizontal plane.

[0101] Furthermore, the annular member 42 is rotatably mounted on the mounting seat 43. For example, the annular member 42 can be mounted on the mounting seat 43 via a plane bearing 45, which supports the annular member 42 and enables the annular member 42 to rotate smoothly.

[0102] For example, referring to Figures 11 to 13The driving structure 4 further includes a mounting bracket 46 , on which the driving member 41 and the mounting seat 43 are both arranged, and the mounting bracket 46 is mounted on the base station base 1 .

[0103] Alternatively, in another specific implementation, the spherical cavity and ball head can be omitted. In this case, the drive structure includes a drive member and a circular ring member. One end of the nozzle in its extension direction is inserted into the center hole of the circular ring member and connected to the circular ring member. The other end has a water spray outlet. The drive member can drive the circular ring member to rotate about its own central axis to drive the nozzle. In this case, the circular trajectory formed by the nozzle at both ends of its extension direction is the same size.

[0104] In this case, the annular member can be a face gear, and the driving member can be a motor. The motor drives the face gear to rotate around its own central axis through a transmission gear meshing with the face gear, thereby driving the nozzle. Alternatively, the annular member can be a bevel gear, and the driving member can be a motor. The motor drives the annular member through another bevel gear meshing with the annular member. Alternatively, the rotation of the annular member can be achieved by friction between the transmission member and the annular member, and the transmission member is driven by the driving member. For example, the transmission member is a transmission belt wound around the annular member, and the driving member can drive the transmission belt to drive the annular member to rotate. The driving member can be a motor, and the motor drives the transmission belt to rotate through a drive wheel.

[0105] In some embodiments, reference Figures 14 to 18 The water spraying structure 3 includes at least one nozzle 31 , and the driving structure 4 drives the at least one nozzle 31 to rotate to spray water into the cleaning tray 2 .

[0106] It is understandable that the water spraying structure 3 may include one or more nozzles 31 , which rotate under the drive of the driving structure 4 to spray water into the cleaning disk 2 , thereby increasing the water spraying range of the nozzle 31 and better cleaning the cleaning disk 2 .

[0107] Each driving structure 4 may drive one nozzle 31 to rotate, or each driving structure 4 may drive multiple nozzles 31 to rotate synchronously.

[0108] For example, in a specific implementation, referring to Figure 14 A drain trough 21 is provided on one side of the cleaning disc 2 in the first direction, a water spray structure 3 is provided on the other side of the cleaning disc 2 in the first direction, and a driving structure 4 drives the nozzle 31 to rotate around a central axis extending along the second direction. One of the first direction and the second direction is the width direction of the cleaning disc 2, and the other is the length direction of the cleaning disc 2.

[0109] Taking the first direction as the length direction of the cleaning disc 2 as an example, the driving structure 4 can drive the nozzle 31 to rotate so that the water flow gradually moves from the side of the cleaning disc 2 away from the drain trough 21 in the length direction to the direction close to the drain trough 21, thereby directly pushing the dirt on the cleaning disc 2 into the drain trough 21. At this time, the movement trajectory of the end of the nozzle 31 with the water outlet is an arc. Figure 14 The X direction shown in the second direction is Figure 14 Y direction shown in .

[0110] In addition, the water spraying structure 3 includes a plurality of nozzles 31 , and the plurality of nozzles 31 are arranged at intervals in the second direction of the cleaning tray 2 . At this time, the driving structure 4 drives the plurality of nozzles 31 to rotate simultaneously.

[0111] It should be noted that at this time, the pressure of the water sprayed from the nozzle 31 can be increased to increase the impact force of the water flow, which can increase the driving force on the dirt on the cleaning plate 2, which is conducive to the dirt quickly entering the drain tank 21 and being extracted by the sewage extraction structure.

[0112] For example, referring to Figure 14 The cleaning base station also includes a sewage tank (not shown in the figure) arranged on the base station base 1. The sewage pumping pipe 10 connected to the sewage tank extends into the sewage tank 21. The sewage pumping structure can vacuum the sewage tank so that the dirt enters the sewage tank through the sewage pumping pipe 10. Among them, the sewage pumping structure can be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc. to achieve vacuuming of the sewage tank. Of course, the above-mentioned sewage tank can be provided with a sewage outlet, and the sewage outlet is connected to the sewage pumping structure. For example, a silencer cavity connected to the sewage outlet is provided on the base of the base station, and the sewage tank is connected to the silencer cavity through the sewage pumping pipe. The sewage pumping structure can vacuum the sewage tank so that the dirt enters the sewage tank through the sewage outlet, the silencer cavity and the sewage pumping pipe.

[0113] Reference Figure 15 and Figure 16 The driving structure 4 includes a driving member 41 and a mounting bracket 46 . The nozzle 31 is disposed on the mounting bracket 46 . The driving member 41 drives the mounting bracket 46 to rotate to drive the nozzle 31 .

[0114] The mounting bracket 46 is rotatably mounted on the base station base 1 and can rotate around an axis extending along the second direction under the drive of the driving member 41. The nozzle 31 is mounted on the mounting bracket 46 and can rotate synchronously with the mounting bracket 46.

[0115] Furthermore, the driving structure 4 further includes a transmission member 44 , which connects the driving member 41 and the mounting bracket 46 . The driving member 41 drives the mounting bracket 46 to rotate via the transmission member 44 .

[0116] Specifically, refer to Figures 15 to 18The mounting bracket 46 has a first position and a second position within the rotation range. When the mounting bracket 46 is in the first position, the nozzle 31 can spray water vertically downward. At this time, the section of the nozzle 31 with the water outlet extends in the vertical direction or extends approximately in the vertical direction, such as Figure 15 As shown, the state of the nozzle 31 at this time is as follows Figure 18 The nozzle 31 is indicated by the dotted line. When the mounting bracket 46 is in the second position, the extension direction of the section of the nozzle 31 having the water outlet is close to horizontal. Figure 16 As shown, the state of the nozzle 31 at this time is as follows Figure 18 The nozzle 31 is indicated by the solid line. As the mounting bracket 46 rotates from the first position to the second position, the water jet from the nozzle 31 gradually approaches the side of the cleaning tray 2 having the drain trough 21, thereby pushing the dirt in the cleaning tray 2 into the drain trough.

[0117] It is understandable that when the mounting bracket 46 rotates from the second position to the first position, the nozzle 31 can be controlled to stop spraying water to prevent the dirt in the cleaning tray 2 from moving away from the drain tank 21 under the action of the water flow, causing secondary pollution.
