[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] See also Figure 1 and Figure 2 A cleaning device provided in one embodiment of the present application includes a body 10, a cleaning roller 20, a scraping member 30 and a sewage collecting assembly 40.

[0031] See also Figure 1 and Figure 2 The cleaning roller 20 is rotatably mounted on the bottom of the body 10, and the cleaning roller 20 can rotate around its central axis to clean the surface to be cleaned.

[0032] See also Figure 2 and Figure 3 The scraping member 30 is extended along the axial direction of the cleaning roller 20 , and the scraping member 30 contacts the outer peripheral surface of the cleaning roller 20 . When the cleaning roller 20 rotates around its central axis, the scraping member 30 can scrape the cleaning roller 20 .

[0033] It is understandable that there is a certain amount of interference between the scraping member 30 and the outer circumference of the cleaning roller 20. When the cleaning roller 20 rotates clockwise around its central axis, the scraping member 30 scrapes the sewage on the outer surface of the cleaning roller 20 in a counterclockwise direction.

[0034] Optionally, the scraping member 30 is a scraping bar whose length is greater than or equal to the axial length of the cleaning roller 20 , so that the scraping bar can contact all positions of the cleaning roller 20 along the axial direction, thereby scraping off all the sewage on the cleaning roller 20 .

[0035] See also Figure 2 , Figure 3 and Figure 5 The sewage collecting assembly 40 is mounted on the body 10, and is disposed on one side of the cleaning roller 20 along the axial direction of the cleaning roller 20. The sewage collecting assembly 40 includes a sewage tank 41, and the sewage tank 41 is provided with a sewage collecting groove 4112, a sewage inlet hole 4113, and a sewage cavity 4111. The sewage collecting groove 4112 is disposed on the side of the sewage tank 41 facing the cleaning roller 20, and the sewage collecting groove 4112 is used to receive the sewage scraped off the cleaning roller 20 by the scraping member 30. The sewage collecting groove 4112 is connected to the sewage cavity 4111 through the sewage inlet hole 4113.

[0036] When the cleaning device performs the cleaning task, the cleaning device moves forward, and the cleaning drum 20 rotates around its central axis to remove dirt such as mud, sand, and dust from the surface to be cleaned, resulting in sewage containing mud, sand, and dust adhering to the outer peripheral surface of the cleaning drum 20. During the rotation of the cleaning drum 20 around its central axis, the scraper 30 scrapes the cleaning drum 20 to separate the sewage from the cleaning drum 20. The separated sewage falls into the sewage collecting tank 4112 under the action of its own gravity, and the sewage in the sewage collecting tank 4112 flows into the sewage chamber 4111 through the sewage inlet hole 4113.

[0037] It should be noted that since sewage contains silt, etc., in order to prevent the silt from blocking the sewage inlet hole 4113, the diameter of the sewage inlet hole 4113 can be increased to ensure that the sewage can flow into the sewage tank 41. Among them, the diameter of the sewage inlet hole 4113 can be set according to actual needs and is not specifically limited here.

[0038] In one embodiment, see Figure 5 The cleaning device also includes a self-cleaning component 50. Optionally, the self-cleaning component 50 is installed on the fuselage 10, the sewage tank 41 or the base station. The self-cleaning component 50 is used to clean the dirt in the sewage trough 4112. After the cleaning device is used for a long time, the mud and sand in the sewage will be deposited in the sewage trough 4112. Therefore, in this embodiment, by providing the self-cleaning component 50, the self-cleaning component 50 can clean the mud and sand and other dirt deposited in the sewage trough 4112, realize the self-cleaning of the sewage trough 4112, and ensure that the sewage trough 4112 can receive the sewage scraped off the cleaning roller 20 by the scraper 30.

[0039] In one embodiment, see Figure 5The self-cleaning component 50 includes a self-cleaning nozzle 51 and an air pump. The self-cleaning nozzle 51 is installed on the fuselage 10 or the sewage tank 41, and the self-cleaning nozzle 51 extends into the sewage collecting tank 4112. The air pump is installed on the fuselage 10, and the air pump has an air outlet, and the air outlet is connected to an air pipe, and the end of the air pipe away from the air pump is connected to the self-cleaning nozzle 51. After the cleaning equipment completes a periodic cleaning task, the air pump pumps gas to the self-cleaning nozzle 51, and the self-cleaning nozzle 51 blows air into the sewage collecting tank 4112 to blow dirt such as mud and sand in the sewage collecting tank 4112 to the sewage inlet hole 4113, thereby realizing self-cleaning of the sewage collecting tank 4112.

[0040] In another embodiment, the cleaning device further includes a dust collecting fan, which is installed on the body 10 .

[0041] Furthermore, the self-cleaning component 50 also includes a self-cleaning nozzle 51, which is installed on the fuselage 10 or the sewage tank 41, and the self-cleaning nozzle 51 extends into the sewage collecting tank 4112. The self-cleaning nozzle 51 is connected to an air pipe, and the end of the air pipe away from the self-cleaning nozzle 51 is arranged at the location of the dust collecting fan. After the cleaning equipment completes a periodic cleaning task, the dust collecting fan is started, and the gas generated by the dust collecting fan reaches the self-cleaning nozzle 51 through the air pipe. The self-cleaning nozzle 51 blows air into the sewage collecting tank 4112 to blow the dirt such as mud and sand in the sewage collecting tank 4112 to the sewage inlet hole 4113, thereby realizing the self-cleaning of the sewage collecting tank 4112. In this way, by rationally utilizing the gas generated by the dust collecting fan, there is no need to add additional components.

[0042] In another embodiment, see Figure 5 The cleaning device also includes a clean water tank, which is installed on the fuselage 10.

[0043] Furthermore, the self-cleaning component 50 includes a self-cleaning nozzle 51 and a suction piece. The self-cleaning nozzle 51 is installed on the fuselage 10 or the sewage tank 41, and the self-cleaning nozzle 51 extends into the sewage trough 4112. The suction piece is installed on the fuselage 10, and optionally, the suction piece is a water pump. The suction piece has a water inlet and a water outlet connected to the water inlet, the water inlet is connected to the clean water tank through a water pipe, and the water outlet is connected to the self-cleaning nozzle 51 through a water pipe. After the equipment to be cleaned completes a periodic cleaning task, the suction piece is started, and the suction piece pumps the water in the clean water tank to the self-cleaning nozzle 51, and the self-cleaning nozzle 51 sprays water into the sewage trough 4112 to flush dirt such as mud and sand in the sewage trough 4112 to the sewage inlet hole 4113, thereby realizing self-cleaning of the sewage trough 4112.

[0044] Of course, in other embodiments, the self-cleaning nozzle 51 can also be set on the base station. Specifically, the base station includes a clean water bucket and a delivery pump, the delivery pump has a water inlet and a water outlet connected to the water inlet, the water inlet is connected to the clean water bucket through a water pipe, and the water outlet is connected to the self-cleaning nozzle 51 through a water pipe. When the cleaning device completes a periodic cleaning task and docks at the base station, the self-cleaning nozzle 51 extends into the sewage collection tank 4112, the delivery pump pumps the water in the clean water bucket to the self-cleaning nozzle 51, and the self-cleaning nozzle 51 sprays water into the sewage collection tank 4112 to flush the dirt such as mud and sand in the sewage collection tank 4112 to the sewage inlet hole 4113, thereby realizing the self-cleaning of the sewage collection tank 4112.

[0045] Furthermore, the base station also includes a sensor and a controller. The sensor is used to detect whether the cleaning device is docked at the base station. The controller is electrically connected to the sensor and the delivery pump. When the sensor detects that the cleaning device is docked at the base station, the sensor sends a signal to the controller, and the controller controls the delivery pump to start, and the delivery pump pumps the water in the clean water bucket to the self-cleaning nozzle 51.

[0046] In another embodiment, the self-cleaning assembly 50 includes a screw conveyor installed in the dirt collection tank 4112, and the screw conveyor is used to convey the dirt in the dirt collection tank 4112 to the dirt inlet hole 4113. When the cleaning device performs a cleaning task or after the cleaning device completes a periodic cleaning task, the screw conveyor rotates to convey dirt such as mud and sand in the dirt collection tank 4112 to the dirt inlet hole 4113.

[0047] In another embodiment, the self-cleaning component 50 further includes a driving member and a cleaning brush. The driving member is mounted on the body 10 or the sewage tank 41, and optionally, the driving member is a motor. The cleaning brush is arranged in the dirt collecting tank 4112, and the cleaning brush includes a connecting shaft and bristles. The connecting shaft is arranged along the length direction of the dirt collecting tank 4112, and the connecting shaft is connected to the driving member, and the bristles are evenly distributed in the axial direction and circumferential direction of the connecting shaft. Driven by the driving member, the connecting shaft rotates around its own axis to drive the bristles to scrub the wall and bottom of the dirt collecting tank 4112, thereby realizing the self-cleaning of the dirt collecting tank 4112.

[0048] It can be understood that the length direction of the dirt collecting groove 4112 is parallel to the axial direction of the cleaning roller 20.

[0049] In another embodiment, the self-cleaning component 50 includes a linear module and a scraper. The linear module is installed on the body 10 or the sewage tank 41. Optionally, the linear module is a screw module, a transmission belt module, etc. The scraper is arranged in the sewage collecting tank 4112, and the scraper is connected to the linear module. The linear module is used to drive the scraper to move along the length direction of the sewage collecting tank 4112. After the cleaning equipment completes a periodic cleaning task, the linear module drives the scraper to move along the length direction of the sewage collecting tank to scrape off the dirt in the sewage collecting tank 4112 and push the scraped dirt to the sewage inlet hole 4113, thereby realizing the self-cleaning of the sewage collecting tank 4112.

[0050] In one embodiment, see Figure 5 The wall of the sewage collecting tank 4112 includes a first wall 41121 and a second wall 41122. The first wall 41121 is arranged close to the cleaning roller 20, and the second wall 41122 is arranged away from the cleaning roller 20. The sewage inlet hole 4113 is arranged in the second wall 41122, and optionally, the sewage inlet hole 4113 is arranged close to the bottom of the tank. In this way, by arranging the sewage inlet hole 4113 in the second wall 41122, the sewage inlet hole 4113 is arranged close to the sewage chamber 4111, which can simplify the structure connecting the sewage collecting tank 4112 and the filter chamber 421, and at the same time, it is conducive to the sewage in the sewage collecting tank 4112 to flow quickly into the filter chamber 421.

[0051] In one embodiment, see Figure 4 and Figure 5 The bottom of the sewage collecting groove 4112 is inclined or curved from the first groove wall 41121 to the second groove wall 41122 in a direction away from the groove opening. When in use, the sewage separated from the cleaning roller 20 falls into the sewage collecting groove 4112, and under the guidance of the groove bottom, the sewage flows toward the direction close to the second groove wall 41122, and then flows into the sewage tank 41 from the sewage inlet hole 4113 on the second groove wall 41122, so that the flow speed of the sewage can be increased.

[0052] In one embodiment, see Figure 5 The sewage inlet hole 4113 is arranged in the middle of the length direction of the second groove wall 41122.

[0053] Further, see Figure 5 At least two self-cleaning nozzles 51 are provided, and all the self-cleaning nozzles 51 are respectively provided at both ends of the length direction of the sewage collecting tank 4112. In this way, the self-cleaning nozzles 51 at both ends of the sewage collecting tank 4112 blow air or spray water in opposite directions, so that the dirt such as mud and sand at both ends of the sewage collecting tank 4112 can be quickly flushed to the sewage inlet hole 4113.

[0054] Of course, in other embodiments, the sewage inlet hole 4113 may also be disposed at one end of the second groove wall 41122 in the length direction, and the self-cleaning nozzle 51 is disposed at one end of the sewage collecting groove 4112 away from the sewage inlet hole 4113. In this way, the self-cleaning nozzle 51 blows air or sprays water in the direction of the sewage inlet hole 4113, and the sewage in the sewage collecting groove 4112 can be sent to the sewage inlet hole 4113, so as to realize the self-cleaning of the sewage collecting groove 4112.

[0055] In one embodiment, see Figure 3 , the sewage collection component 40 also includes a filter 42. The filter 42 is arranged in the sewage cavity 4111, and the filter 42 is used to filter the sewage flowing into the sewage tank 41 through the sewage inlet hole 4113. When the cleaning device performs the cleaning task, the sewage in the sewage collection tank 4112 flows into the sewage tank 41 through the sewage inlet hole 4113. Since the sewage cavity 4111 is equipped with the filter 42, the filter 42 filters the sewage, and the filtered sewage falls into the sewage cavity 4111 under its own gravity for storage. With this arrangement, even if the sewage contains dirt such as mud and sand, the sewage can flow into the sewage tank 41, avoiding functional errors of the cleaning device and ensuring that the user can use the cleaning device normally.

[0056] In one embodiment, see Figure 6 The filter element 42 is a filter screen. The filter screen is provided with a filter cavity 421 and filter holes. The filter cavity 421 is connected with the sewage inlet hole 4113 , and the filter holes are connected with the filter cavity 421 and the sewage cavity 4111 .

[0057] Of course, in other embodiments, the filter element 42 may also be a filter screen, which is transversely disposed in the sewage tank 41 , and the filter screen and the sewage tank 41 are surrounded to form a filter cavity, and the space above the filter screen is the filter cavity 421 .

[0058] In one embodiment, see Figure 6 The filter element 42 is provided with a plug hole 423, and the plug hole 423 is connected to the filter cavity 421. The sewage collection component 40 also includes a sewage pipe 43. One end of the sewage pipe 43 is connected to the sewage inlet hole 4113, and the other end of the sewage pipe 43 is arranged in the plug hole 423 and connected to the filter cavity 421.

[0059] Optionally, see Figure 6 The bottom of the sewage tank 41 is integrally formed with a sewage pipe 43, which is arranged along the height direction of the sewage tank 41. One end of the sewage pipe 43 is arranged in the plug hole 423, and the side of the other end of the sewage pipe 43 is provided with a communication hole, which is connected to the sewage inlet hole 4113.

[0060] In one embodiment, see Figure 5 and Figure 6The sewage tank 41 includes a box body 411 and a cover body 412. The top of the box body 411 is provided with an opening 4114, and the cover body 412 is openably arranged at the opening 4114. Optionally, one side of the cover body 412 is hinged to the box body 411. When in use, the cover body 412 is opened to clean the dirt on the filter element 42.

[0061] In one embodiment, the inner wall of the box body 411 is provided with a first overlap portion. The side of the filter element 42 is provided with a second overlap portion, and the second overlap portion overlaps the first overlap portion. When in use, the second overlap portion overlaps the first overlap portion, so that the filter element 42 can be detachably installed on the box body 411, which is convenient for disassembly and assembly of the filter element 42.

[0062] In one embodiment, see Figure 4 The cover 412 is provided with a neck 4121 on one side facing the filter element 42. When the cover 412 is covered on the opening 4114, the neck 4121 is pressed against the second overlap portion on the side away from the cover 412. When sewage flows into the sewage cavity 4111, the sewage will generate an impact force on the filter element 42. Since the neck 4121 is pressed against the second overlap portion, the filter element 42 can be prevented from moving, thereby improving the stability of the installation of the filter element 42.

[0063] Further, see Figure 4 The neck 4121 is sleeved with a sealing member 4122, and the outer peripheral surface of the sealing member 4122 abuts against the inner wall of the sewage tank 41. In this way, the sealing member 4122 can play a sealing role to prevent the sewage in the sewage tank 41 from flowing out from the gap between the box body 411 and the cover body 412. At the same time, the sealing member 4122 also plays a role in preventing loosening, so that the cover body 412 is stably and reliably arranged at the position of the opening 4114, and the cover body 412 is prevented from opening under the impact of sewage.
