[0023] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0024] refer to Figure 1 , Figure 1 The schematic diagram of the structure of a sweeping robot is shown in FIG. Figure 2 The figure is a side view of a sweeping robot, which comprises at least:

[0025] Ontology 1.

[0026] The first cleaning assembly 2 is located at the bottom 101 of the main body 1 and is used for mopping the floor; wherein the first cleaning assembly 2 is a roller-type cleaning assembly.

[0027] The second cleaning component 3 is located at the bottom 101 and behind the first cleaning component 2 in a preset direction, and is at least used to remove moisture remaining on the ground after mopping by the first cleaning component 2; wherein the preset direction is the moving direction of the sweeping robot when mopping the ground.

[0028] The body 1 is the main part of the sweeping robot, which may include at least a shell and some internal components, and can realize some functions of the sweeping robot.

[0029] The structure, shape and size of the body 1 can be determined according to actual usage and are not limited here. The bottom of the body 1 can be the part facing the ground.

[0030] The first cleaning assembly 2 is located at the bottom 101 of the body 1. The first cleaning assembly 2 is a drum-type cleaning assembly used for mopping the floor. Since the first cleaning assembly 2 is a drum-type cleaning assembly, when the sweeping robot cleans the floor through the first cleaning assembly 2, the first cleaning assembly 2 is in contact with the floor and is in a rotating state, and the floor can be cleaned during the rotation of the first cleaning assembly 2.

[0031] Exemplarily, the first cleaning assembly 2 may include a drum and a mop, wherein the mop is located on the surface of the drum and wraps around the surface of the drum. When the drum rotates, the mop is driven to rotate, thereby cleaning the floor with the mop.

[0032] For example, the material and type of the mop are not limited and can be determined according to actual needs. For example, the mop can be made of cotton, linen or other materials.

[0033] Exemplarily, the mop cloth may be replaced with other alternative parts having the same function.

[0034] The first cleaning component 2 may be a component with humidity, and the first cleaning component 2 contains a certain amount of moisture. When the sweeping robot cleans the floor through the first cleaning component 2, the first cleaning component 2 may moisten the floor and clean the floor. This process may be called a mopping process.

[0035] Exemplarily, the first cleaning component 2 can be a water spray component in the sweeping robot that transports water in the water tank to the first cleaning component 2 during the cleaning process of the sweeping robot, or the water spray component sprays the water in the water tank onto the ground, and the first cleaning component 2 cleans the ground in combination with the water sprayed onto the ground.

[0036] Exemplarily, the objects to be cleaned on the ground cleaned by the first cleaning component 2 may at least include: dust, hair, oil stains or other dirt on the ground.

[0037] The second cleaning component 3 can be a component for removing moisture remaining on the ground after the first cleaning component 2 mops the ground, and any component that can achieve this function can be regarded as the second cleaning component 3. The structure, size, material, etc. of the second cleaning component 3 can be determined according to actual needs.

[0038] When the robot vacuum cleaner is mopping the floor, the robot vacuum cleaner will move in a preset direction, which may be the direction in which the robot vacuum cleaner moves toward the area to be cleaned when mopping the floor, and the moving direction may include the front, i.e., the forward direction. In the preset direction, the second cleaning component 3 is located behind the first cleaning component 2.

[0039] In the process of moving in the moving direction, the sweeping robot will first clean the ground with the first cleaning component 2. Since water stains will be left on the ground after the first cleaning component 2 cleans the ground, the second cleaning component 3 will clean the area cleaned by the first cleaning component 2 again, and the second cleaning component 3 can absorb and wipe the water stains left by the first cleaning component 2, so as to wipe the ground clean.

[0040] The mopping assembly in the sweeping robot is a drum-type cleaning assembly. After mopping the floor with the drum-type mopping assembly, the problem of poor cleaning effect between the two discs after mopping the floor with the double-disc mopping assembly is reduced, and the situation of incomplete cleaning caused by the relatively poor cleaning force of the flat-plate mopping assembly is also reduced. In addition, the second cleaning assembly can clean the moisture left on the ground after mopping the floor by the first cleaning assembly, and the ground can be cleaned by combining with the first cleaning assembly, which reduces the moisture left on the ground after mopping the floor, improves the cleaning effect, and improves the user experience.

[0041] In one embodiment, reference Figure 3 , is another schematic diagram of a sweeping robot, the bottom 101 of the body 1 has:

[0042] The groove 1011 is used to accommodate the first cleaning component 2, and has a first side wall 10111 and a second side wall (not shown in the figure) opposite to each other. The first cleaning component 2 is rotatably connected to the body 1 through the first side wall 10111 and the second side wall.

[0043] When the first cleaning component 2 is located in the groove 1011 , the first cleaning component 2 can rotate, and the floor surface can be cleaned by the rotation of the first cleaning component 2 .

[0044] When the first cleaning component 2 is located in the groove 1011 , a portion of the first cleaning component 2 is located in the groove 1011 , and the remaining portion is located outside the groove 1011 and protrudes from the bottom surface 102 of the body 1 .

[0045] Since the first cleaning component 2 is a roller-type cleaning component with a corresponding thickness, and the first cleaning component 2 needs to be installed on the main body 1, the groove 1011 on the bottom 101 of the main body 1 can provide an installation space for the first cleaning component 2, and the groove 1011 can accommodate the first cleaning component 2.

[0046] Illustratively, the thickness of the roller may be greater than or equal to the diameter of the roller.

[0047] like Figure 1 As shown, a portion of the first cleaning component 2 is located in the groove 1011, and the remaining portion is located outside the groove 1011 and protrudes from the bottom surface 102 of the body 1. The portion of the first cleaning component 2 protruding from the bottom surface 102 of the body 1 can be referred to Figure 1 102 shown.

[0048] refer to Figure 4 , is a schematic diagram of a first cleaning component 2. The first cleaning component 2 may include:

[0049] The roller 201 and the rotating shaft 202, the rotating shaft 202 is fixed on the axis of the roller 201, the rotating shaft 202 is used to fix the roller 201 on the body 1, and is also connected to the driving assembly in the sweeping robot, for transmitting the driving force of the driving assembly to the roller 201, so that the driving assembly drives the roller 201 to rotate. The driving assembly is not shown, and the connection relationship between the driving assembly and the first cleaning assembly 2 is not limited. The way in which the driving assembly can drive the first cleaning assembly 2 to rotate is within the protection scope of this embodiment. For example, the rotating shaft 202 and the driving assembly are connected by gears or transmission shafts. For another example, the driving assembly is a motor, and the rotating shaft 202 is directly connected to the rotor of the motor.

[0050] In one embodiment, the rotating shaft 202 may be inserted into the drum 201 .

[0051] In one embodiment, there are two rotating shafts 202, which are respectively located at the center of the top surface and the center of the bottom surface of the drum 201, and the rotating shafts 202 are perpendicular to the top surface and the bottom surface. The top surface and the bottom surface of the drum 201 are parallel.

[0052] In one embodiment, reference Figure 2 The groove 1011 has through holes 10112 on the first side wall and the second side wall in the extension direction of the roller 201, respectively, for installing the rotating shaft 202, that is, the rotating shaft 202 is penetrated into the through hole 10112, so as to fix the first cleaning component 2 on the body 1 and realize the connection between the driving component and the rotating shaft 202 in the sweeping robot.

[0053] In one embodiment, reference Figure 1 Since the first cleaning component 2 is a roller type, the direction of the axis of the roller is the extension direction of the first cleaning component 2. In the extension direction of the first cleaning component 2, the length of the second cleaning component 3 is greater than or equal to the length of the first cleaning component 2.

[0054] After the first cleaning component 2 cleans the floor, the second cleaning component 3 can wipe off the water remaining on the floor after the first cleaning component 2 cleans, thereby reducing the residual moisture in the first cleaning component 2, improving the cleaning efficiency, and improving the user experience.

[0055] In one embodiment, the second cleaning component 3 is a dry compressible cleaning component, and the second cleaning component 3 is water-absorbent. In this way, the second cleaning component 3 can absorb the moisture remaining after the first cleaning component cleans the ground, and when encountering some fixed objects on the ground, the thickness of the second cleaning component 3 can be compressed, so that the sweeping robot can pass through the fixed objects.

[0056] Exemplarily, the second cleaning component 3 may include at least: a dry sponge and / or a cotton cloth.

[0057] In one embodiment, the fixing method of the second cleaning component 3 and the main body 1 is not limited, and can be snap-fitting or bonding.

[0058] In one embodiment, the cleaning robot further includes:

[0059] The third cleaning component 4 is located between the first cleaning component 2 and the second cleaning component 3 and close to the opening of the groove 1011, and is used to collect the moisture remaining on the ground after the first cleaning component 2 mops the ground into the opening.

[0060] The air suction port (not shown in the figure) is located on the preset inner wall of the groove 1011 and is used to absorb the moisture collected by the third cleaning component 4; wherein the preset inner wall is the inner wall close to the second cleaning component 3.

[0061] During the cleaning process, the first cleaning component 2 first mops the floor, and moisture will remain on the floor. Then the third cleaning component 4 can contact the floor and collect the moisture remaining on the floor near the opening of the groove 1011. Then the airflow at the air suction port sucks away the moisture collected by the third cleaning component 4 and sucks it into the sewage tank of the sweeping robot.

[0062] Exemplarily, the sweeping robot further includes: a fan, wherein an air duct of the fan is connected to the air suction port, and is used to generate an airflow for absorbing moisture;

[0063] The sewage tank is used to store the water sucked in through the air inlet and collected from the third cleaning component 4 to the opening.

[0064] In one embodiment, the distance that the third cleaning component 4 protrudes from the bottom surface 102 is the same as the distance that the first cleaning component 2 protrudes from the bottom surface 102. This makes it easier for the third cleaning component 4 to collect the moisture left on the ground by the first cleaning component 2.

[0065] In one embodiment, the third cleaning component 4 includes a scraper bar. The length of the scraper bar is greater than or equal to the length of the first cleaning component 2. This can facilitate the collection of moisture remaining on the ground and reduce the situation of missing the collection of some moisture remaining on the ground.

[0066] For example, the material and shape of the scraper strip are not limited and can be determined according to actual needs. For example, the scraper strip can be made of rubber or plastic, or can be a long strip.

[0067] In one embodiment, the fixing method of the third cleaning component 4 and the main body 1 is not limited, and can be snap-fitting or bonding.

[0068] In one embodiment, reference Figure 1 and Figure 3 , the sweeping robot also includes:

[0069] The fourth cleaning assembly 5 is located at the bottom 101 of the main body 1 and at a side of the first cleaning assembly 2 away from the second cleaning assembly 3 , and is used for sweeping the floor.

[0070] The fourth cleaning component 5 may include a roller brush 501 and a baffle 502. The roller brush 501 is used to clean the objects to be cleaned on the ground, and the baffle 502 is used to collect or gather the objects to be cleaned that are not cleaned by the roller brush 501, so as to facilitate the roller brush 501 to clean these objects to be cleaned again.

[0071] The roller brush 501 and the baffle 502 are arranged adjacent to each other. The baffle 502 can be located between the roller brush 501 and the first cleaning component 2 and close to the roller brush 501 .

[0072] The first cleaning component 2 is located between the second cleaning component 3 and the fourth cleaning component 5. During the cleaning process of the sweeping robot, the fourth cleaning component 5 first cleans the floor and removes the debris on the floor. Then, the first cleaning component 2 cleans the floor, the fourth cleaning component 5 can be used as sweeping, the first cleaning component 2 can be used as mopping, and finally, the second cleaning component 3 wipes the floor dry. The combination of the three cleaning components improves the cleaning effect and the user experience.

[0073] Exemplarily, the roller brush 501 also has an air suction port for absorbing the debris cleaned by the fourth cleaning component 5 into the storage space inside the sweeping robot.

[0074] The air suction port located on the preset inner wall of the groove 1011 can be recorded as the first air suction port, and the air suction port at the roller brush 501 can be recorded as the second air suction port. The two air suction ports can share a fan and each has an air duct.

[0075] Exemplarily, the baffle 502 may include a scraper strip, which may be a strip-shaped structure. The material and size are not limited and may be determined according to actual usage requirements.

[0076] Exemplarily, the cleaning robot further includes a garbage storage box for storing objects cleaned by the fourth cleaning component 5 .

[0077] In one embodiment, the cleaning robot further includes:

[0078] A water tank, located inside the body 1, for storing water used by the first cleaning assembly 2 to mop the floor;

[0079] The water spraying assembly is connected to the water tank and is used to spray the water in the water tank onto the ground or the first cleaning assembly 2 .

[0080] The water tank and the water spray assembly are not shown in the figure, but are located inside the body 1. The positional relationship and connection relationship of the water tank and the water spray assembly inside the body 1 can be determined according to actual use. The sweeping robot in this embodiment only needs to have a water tank and a water spray assembly.

[0081] In another embodiment, an example of a sweeping robot is also provided.

[0082] Most sweepers use a sweeping roller brush with a double-disc mop or a flat mop. As usage requirements increase, the shortcomings of these two solutions are gradually exposed. Double-disc mops often leave gaps in the middle that are difficult to clean, and flat mops have relatively poor cleaning power. Both types of mops leave a lot of residual water after mopping.

[0083] The sweeping robot provided in this embodiment includes: a body 1 (e.g., a sweeping machine body), a roller brush 501 (e.g., a middle sweeping roller brush), a baffle 502 (e.g., a middle sweeping scraper), a first cleaning component 2 (e.g., a roller mop), a third cleaning component 4 (e.g., a mopping scraper), and a second cleaning component 3 (e.g., a flat wiping cloth). The positional relationship and connection relationship can be referred to in Figures 1 to 4 .

[0084] This embodiment adopts a middle sweeping roller brush for strong cleaning, and with the suction of the fan, the garbage and dust passing by can be cleaned into the dust box. After cleaning, the roller mop is used to mop the floor, and the mopping strip can clean some water. At the same time, the fan generates suction to suck the dirty water into the sewage tank. Even so, there are still water marks on the ground, which are wiped dry with a flat wiping cloth, so that the ground after cleaning is free of dust, dirt and water stains, and is cleaned once.

[0085] This technical solution is applied in the cleaning process of the sweeper. The cleaning part mainly includes a middle sweeping roller brush, a roller mop, and a flat cloth for wiping. When in use, the front middle sweeping roller brush cooperates with the suction of the fan to sweep the solid garbage and dust on the ground into the dust box. The middle roller mop is wetted with water for mopping the floor. The built-in scraper can scrape the dirty water off and suck it into the sewage tank through the suction port. If there is water remaining on the ground after sweeping and mopping, the flat dry cloth at the rear is used to wipe it dry.

[0086] The middle sweep roller brush and the middle sweep scraper can be made into floating type, which can improve the cleaning effect. The roller mop and the mopping scraper can also be made into floating type, so that the floor is cleaned with constant pressure. The flat wiping cloth is made of highly absorbent material and has a certain thickness. The water after wiping the floor can soak upwards, and the wiping effect is more obvious.

[0087] This technical solution can clean the floor in one go, without any debris, dirt or water residue on the floor. It can clean the floor in one go, which is more efficient, comprehensive and leaves no gaps. It can wipe away the water residue after mopping the floor, and clean the floor quickly in one go. This technical solution uses a middle sweeping roller brush with a roller mop and a flat plate to wipe away the residual water after mopping the floor, and there will be no uncleaned parts after cleaning, achieving the effect of strong cleaning and no water residue after cleaning.

[0088] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the utility model disclosed herein. The present invention is intended to cover any variation, use or adaptation of the present invention, which follows the general principles of the present invention and includes common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
