In addition, the specific location of the second external port 2032 depends on the layout of the components inside the robot main body 100; in other embodiments of the invention, the second external port 2032 may also be provided in a side wall 2112 of the cassette 211.

Next, a detailed description will be given of the cap plate assembly 220.

Referring to fig. 5 and 6, in conjunction with other figures, the cover plate assembly 220 includes a cover plate 221, the cover plate 221 is a flat plate-shaped structure and is accommodated in the accommodating cavity 201, and the cover plate 221 is movable between a sealing position and an unsealing position to seal or unseal the air suction channel 202 and the air outlet channel 203. Specifically, referring to fig. 12, the cleaning robot 1 further includes a blower assembly 700 having an air inlet 710 connected to the second external port 2032, preferably, a sealing ring is disposed at a connection between the second external port 2032 and the air inlet 710 to prevent air leakage; at the sealing position, the cover plate 221 integrally covers and seals the first inner port 2021 and the second inner port 2031, and at this time, the sewage in the accommodating cavity 201 cannot overflow to the outside of the box body 210 through the air suction channel 202 and the air outlet channel 203, so that safety accidents caused by overflow of the sewage are avoided; in the unsealing position, the cover plate 221 unseals the first inner port 2021 and the second inner port 2031, and the fan assembly 700 can exhaust air from the box 210, so that the first outer port 2022 is in a negative pressure state, which is convenient for sucking dirt on the ground and the cleaning roller 300.

In this embodiment, the cover 221 is rotatably coupled to the housing 210, i.e., the cover 221 is rotatable between a sealed position and an unsealed position. Specifically, the bottom wall and the sidewall of the box 211 are recessed to form a boss 2115, one end of the cover 221 is rotatably connected to the upper surface of the boss 2115, and the other end can pivot around the end to seal or unseal the first inner port 2021 and the second inner port 2031. Alternatively, the direction of the first inner port 2021 pointing to the second inner port 2031 is parallel to the rotation axis X of the cover 221, so that the free end of the cover 221 can move up and down along the direction shown in the figure to synchronously seal or unseal the first inner port 2021 and the second inner port 2031. It is understood that in other embodiments of the present invention, the cover plate 221 may be designed to rotate about the illustrated Y-axis, Z-axis, or other directions. Preferably, the first inner port 2021 is flush with the second inner port 2031, such that when the cover 221 is in the sealed position, one end is carried by the boss 2115 and the other end is carried by the first inner port 2021 and the second inner port 2031. Preferably, in order to enhance the sealing effect of the cover plate 221 on the first inner port 2021 and the second inner port 2031, an elastic sealing element (not shown), such as a rubber sheet or a sealing ring, is fixedly disposed at an end of the cover plate 221 facing the first inner port 2021 and the second inner port 2031, so as to seal the connection between the cover plate 221 and the first inner port 2021 and the second inner port 2031. It should be understood that, in other embodiments of the present invention, the cover 221 may be connected to the box 210 by other means, such as sliding connection, only by ensuring that it can move back and forth between the sealing position and the unsealing position to seal or unseal the air suction channel 202 and the air outlet channel 203, but is not limited to the rotating connection in this embodiment.

Further, in order to avoid that in the process of exhausting air from the storage box 200 by the fan assembly 700, the sewage, garbage and other contaminants entering the storage cavity 201 from the air suction channel 202 directly enter the air outlet channel 203 and move to the inside of the robot main body 100 through the second external port 2032, thereby causing a safety accident to occur to the floor cleaning robot 1, the cover plate assembly 220 further includes a partition plate 222. Specifically, with continued reference to fig. 5 and other figures, one end of the partition 222 is fixed to the cover 221, and the other end extends toward the bottom 2111 of the box 211, and the partition 222 is at least partially located between the first inner port 2021 and the second inner port 2031; dirt such as sewage and garbage entering the receiving cavity 201 from the air suction channel 202 falls into the bottom of the receiving cavity 201 under the blocking action of the partition 222, and the air flow passes over the edge (e.g. bottom and side) of the partition 222 and flows to the fan assembly 700 through the air outlet channel 203. It should be noted that the partition 222 not only can block dirt, but also can accelerate the airflow in the storage cavity 201, thereby enhancing the adsorption force of the storage box 200 on the dirt on the floor and the dirt on the cleaning roller. Preferably, the air outlet channel 203 is further provided with a filter for preventing passage of dirt, while it allows passage of an air flow, preferably a filter cotton.

The scraping part 270 is a convex structure, and is configured to at least partially embed into the cleaning roller 300 when at least a portion of the cleaning roller 300 is received in the receiving slot 204, so as to scrape dirt on the cleaning roller 300, and the dirt is sucked into the receiving cavity 201 through the suction channel 202 under the suction action of the fan assembly 700; at the same time, the scraping portion 270 also functions to separate the first outer port 2022 from the first fluid channel 205, so as to prevent the dirt entering the suction channel 202 from passing through the scraping portion 270 and covering the blocking liquid outlet portion 206.

Further, referring to fig. 6 in combination with other figures, the storage box 200 further has a second liquid passage 207 located in the storage cavity 201 and isolated from the storage cavity 201, the second liquid passage 207 having a liquid inlet 2071 and a liquid outlet 2072; the liquid inlet 2071 is disposed on the box 210 and is used for communicating with the liquid supply mechanism, and the liquid outlet 2072 is communicated with the first liquid channel 205. Then, the cleaning liquid delivered from the liquid outlet end of the liquid supply mechanism will flow to the cleaning roller 300 through the second liquid channel 207, the first liquid channel 205 and the liquid outlet portion 206 in sequence. Preferably, the second fluid passage 207 is gradually far from the top wall of the tank 210 from the fluid inlet 2071 to the fluid outlet 2072. Thus, a height difference is formed between the liquid inlet 2071 and the first liquid channel 205, which can increase the flow rate of the cleaning liquid entering the first liquid channel 205, and further increase the traveling distance of the cleaning liquid along the first liquid channel 205, so that the cleaning roller 300 is more uniformly wetted; this arrangement also avoids water accumulation inside the second fluid passage 207.

Further, in some embodiments, in order to facilitate the floor washing robot 1 to timely acquire the liquid level in the storage box 200 and further guide a user to timely clean up dirt when the liquid level is high, the storage box 200 further includes a float and a first magnet mounted on the float; correspondingly, the housing 110 is provided with a hall element module and a controller, the hall element module includes a first hall element used with the first magnet, and the controller is electrically connected to the first hall element.

In this embodiment, the box body 210 is formed with a surrounding wall 2116 in the receiving cavity 201, the surrounding wall 2116 extends from the bottom wall 211 of the box body toward the top wall, and the surrounding wall 2116 and the bottom wall 2111 and the side wall 2112 of the box body together form the guide groove 208; and the surrounding wall 2116 is opened with a notch extending from the bottom to the top of the receiving chamber 201, and the notch communicates the guide groove 208 and the receiving chamber 201, so that the guide groove 208 communicates with the receiving chamber 201. The float 280 is accommodated in the guide groove 208, and can be lifted and lowered along with the liquid level in the guide groove 208 and the liquid level in the accommodating chamber 201, so as to drive the first magnet 281 mounted thereon to lift and lower together. Optionally, the float 280 is foam; it is understood that in other embodiments of the present invention, the float 280 may be a plastic other than foam, or other material that is less dense than and chemically inert to the wastewater. Further optionally, the box 210 further has a limiting structure (not shown in the drawings), which is accommodated in the accommodating cavity 201 and located at the top end of the guide groove 208, and is used for preventing the float 280 from leaving the guide groove 208 from the top of the guide groove 208; in this embodiment, the stop structure extends at least partially into the channel 208. A first hall element (not shown) is installed at the housing 110 and disposed near the top of the guide groove 208, and is used to cooperate with the first magnet 281 to detect whether the float 280 floats to a predetermined position; the preset position is a position close to the top of the storage cavity 201, when the float 280 floats to the preset position, the first hall element detects that the float is in place, and then a signal is transmitted to the controller, and the controller performs related operations according to the signal so as to guide a user to clean dirt in time.

Specifically, the output module 140 is installed on the top of the housing 110, electrically connected to the controller, and configured to output a warning signal; when the float 280 floats to the preset position, the first hall element detects that the float 280 is in place and sends a signal to the controller, and the controller controls the output module 140 to output a warning signal according to the signal. Optionally, the output module 140 includes a display panel for displaying visual warning signals such as images and texts to prompt the user to clean the dirt in the storage box 200; in addition, in some of other embodiments, the output module 140 may further include an audio output device, where the audio output device is a device capable of outputting sound, such as a speaker, a buzzer, etc., and the audio output device is used for outputting an audible warning signal of a set audio frequency, so as to prompt a user to clean the accommodating box 200; of course, in other embodiments, the output module 140 may also include both a display panel and an audio output device.

Further, in some embodiments, in order to enable the controller to know in time whether the storage box 200 is accommodated in the first groove 101 and is installed in place, so as to facilitate the subsequent cleaning operation, the storage box 200 further includes a second magnet (not shown in the drawings); correspondingly, the hall element module further includes a second hall element (not shown) used in cooperation with the second magnet, and the second hall element is electrically connected to the controller. Specifically, the second magnet is mounted on the box 210, and in this embodiment, the second magnet is disposed in the wall of the box 210 and near the bottom of the box 210 by insert molding; it is understood that in other embodiments of the present invention, the second magnet may be fixed to the box 210 by other means, such as adhesion, screwing, clipping, etc., which are not described in detail herein. A second hall element (not shown) is installed at the housing 110, and is disposed near the bottom of the case 210, and is used for cooperating with a second magnet to detect whether the storage box 200 is installed in place; when the storage box 200 is installed in place, the second hall element detects that the storage box is in place, and then a signal is transmitted to the controller, and the controller controls the floor cleaning robot to be switched to a mode state capable of performing cleaning operation according to the signal, and otherwise, the floor cleaning robot is switched to a mode state incapable of performing cleaning operation.

Further, in some embodiments, to facilitate user access to the receptacle 200, the receptacle 200 further includes a handle. Specifically, referring to fig. 3 and fig. 6 in combination with other figures, the handle 290 is generally arcuate, and both ends of the handle 290 are rotatably mounted on the top or top wall of the side wall 2112 of the box 210, respectively, and can be rotated to be perpendicular or parallel to the top wall of the box 210, so that a user can take the storage box 200 by picking up the middle area of the handle 290. Preferably, the outer surface of the top wall of the box 210 is provided with a handle receiving groove (not shown in the figure) adapted to the handle 290, so that when the storage box 200 is received in the first groove 101, the handle 290 can rotate into the handle receiving groove, so as to avoid the effect of the first flip-open cover 120 covering the opening of the first groove 101 due to the protrusion of the handle 290 on the surface of the box 210.

Furthermore, the present invention further improves the structure of the handle 290 to enhance the fixing effect of the storage box 200 relative to the robot body 100 in the height direction when the storage box is accommodated in the first groove 101. Specifically, referring to fig. 14, which shows a partially enlarged schematic view at B in fig. 6, in combination with other figures, an end of the handle 290 is provided with a limiting groove 291 at an end surface away from the center thereof, the limiting groove 291 extends along a predetermined direction, a first end 2911 of the limiting groove 291 is closed, and a second end 2912 of the limiting groove 291 penetrates through the end of the handle 290 from the first end 2911 along the predetermined direction. Accordingly, the robot body 100 is provided with a limit post (not shown) at a position facing the limit groove 291, and the limit post is used to cooperate with the limit groove 291 to restrict the freedom of movement of the storage box 200 in the height direction of the cleaning robot 1. Specifically, when the storage box 200 is received in the first groove 101 and the handle 290 rotates from the first preset position to the second preset position, the limiting column slides from the second end 2912 of the limiting groove 291 to the first end 2911 relative to the handle 290, and restricts the freedom of movement of the storage box 200 along the height direction of the cleaning robot 1; in the process that the handle 290 rotates from the second predetermined position to the first predetermined position, the position-limiting post is separated from the position-limiting groove 271 from the second end 2912, and the user can freely take out the storage box 200. The first preset position is a position where the handle 290 is vertical to the top wall of the box 210, the second preset position is a position where the handle 290 is parallel to the top wall of the box 210, and at this time, the handle 290 is accommodated in the handle accommodating groove. In this embodiment, the first end 2911 has an axis collinear with the axis of rotation of the handle 290, and the second end 2912 extends in a predetermined direction through the end of the handle. In other embodiments of the present invention, the axis of the first end 2911 may be offset from the rotation axis of the handle 290, and accordingly, the second end 2912 extends along the predetermined direction and penetrates through the end portion, in which the predetermined direction is the rotation direction of the handle 290 from the first predetermined position to the second predetermined position. It is worth mentioning that the arrangement of the limiting groove 291 and the limiting column can remind the user that the containing box 200 can be put forward only by rotating the handle to the vertical position, so as to ensure that the containing box 200 is separated from the overall balance of the first groove 101.

Further, considering that the cleaning roller 300 contacts the ground and the robot main body 100 is higher than the ground when the cleaning robot 1 lands on the ground, during the traveling of the cleaning robot 1, there is no obstruction behind the cleaning roller 300, and the air behind the cleaning roller 300 enters the air suction channel 202 through the gap between the cleaning roller 300 and the robot main body 100, which will reduce the suction effect of the fan assembly 700 on the dirt on the ground, and to overcome this deficiency, the cleaning robot 1 further includes a scraper bar 800. Specifically, referring to fig. 15, which shows a partially enlarged schematic view at C in fig. 4, in combination with other figures, the wiper strip 800 extends in a direction parallel to the axial direction of the cleaning roller 300, is mounted at the bottom of the robot main body 100 and is disposed close to the cleaning roller 300, when the cleaning robot 1 lands, the wiper strip 800 is in interference contact with the ground, and the wiper strip 800 is located behind the cleaning roller 300 in the advancing direction of the cleaning robot 1. The scraper bar 800 is used to form a shelter behind the cleaning roller 300, so as to form a nearly closed negative pressure space together with the cleaning roller 300 and the robot main body 100, and further prevent the outside air from entering the space, thereby improving the negative pressure adsorption effect of the cleaning robot on the floor dirt and the dirt on the cleaning roller 300. The scraper bar 800 is also used for recycling the dirt which is not timely cleaned in the first turnover of the cleaning roller 300 and the dirt which is not timely absorbed to the accommodating cavity 201 by the fan assembly 700, so that the cleaning roller 300 can continuously turnover and the dirt which is recycled by the scraper bar 800 can be continuously absorbed by the fan assembly 700 to be accommodated in the accommodating cavity 201. Optionally, the wiper strip 800 includes a fixing portion 810 and a connecting portion 820; the fixing portion 810 is installed at the bottom of the robot main body 100, one end of the connecting portion 820 is fixed to the fixing portion 810, and the other end extends in a direction away from the robot main body 100. Preferably, the connection part 820 is in interference contact with the floor surface when the cleaning robot 1 is landed. Preferably, the fixing part 820 is at least partially attached to the outer end of the lint 320 of the cleaning roller 300, that is: at least a portion of the wiper strip 800 conforms to the circumferential surface of the scrub roller 300; so, reduced the clearance between scrubbing strip 800 and the cleaning roller 300 on the one hand, reduced the volume in above-mentioned negative pressure space promptly, and then helped promoting fan assembly 700's negative pressure adsorption effect, on the other hand still helps making the great rubbish of volume suitably increase at the frictional force between cleaning roller 300 and scrubbing strip 800, and then the climbing of the great rubbish of volume of being convenient for.

The cleaning robot 1 provided by the embodiment of the invention comprises a robot main body 100, a containing box 200, a cleaning roller 300, a roller power assembly 400, a fan assembly 700, a liquid storage box 500, a liquid supply mechanism and a driving wheel assembly 600. The storage box 200 includes a box 210, a cover assembly 220, a cover driving assembly 230, and a locking assembly 240.

The case 210 includes a case 211, a case cover 212, and a case packing 213. The case cover 212 covers the case 211 and encloses a receiving chamber 201 with the case 211, and the case packing 213 is disposed at a joint between the case cover 212 and the case 211 to seal the joint. Even if the cleaning robot 1 is tilted or turned upside down, the liquid in the storage chamber 201 is prevented from leaking out by the housing packing 213. Therefore, the containing box 200 can effectively avoid the defect that the liquid in the containing cavity 201 seeps outwards; similarly, the cleaning robot 1 including the storage box 200 can also effectively avoid the disadvantage that the liquid in the storage cavity 201 seeps outwards.

The box 210 is provided with a suction channel 202 communicating with the external environments of the storage cavity 201 and the box 210, respectively, and an outlet channel 203 communicating with the external environments of the storage cavity 201 and the box 210, respectively. The cover plate assembly 220 comprises a cover plate 221, wherein the cover plate 221 is accommodated in the accommodating cavity 201 and can move between a sealing position and an unsealing position; in sealed position, the apron seals induced draft passageway and air-out passageway, and in the deblocking position, the apron deblocking induced draft passageway and air-out passageway. Therefore, after the cleaning robot 1 provided by the invention stops working, the storage box 200 can cover the air suction channel 202 and the air outlet channel 203 by enabling the cover plate 221 to be in the sealing position, so as to prevent sewage from overflowing from the air suction channel and the air outlet channel, thereby avoiding the defect that the sewage overflows from the air suction channel 202 and/or the air outlet channel 203 because the cleaning robot 1 is slightly inclined when a user takes the cleaning robot 1.

The cleaning robot 1 utilizes the feature that the wheel arm 610 rotates relative to the robot main body 100 when the cleaning robot is lifted off or landed, and the protrusion 613 disposed on the wheel arm 610 drives the push rod 231 in the cover driving assembly 230 to move between the first position and the second position, and further drives the cover 221 to move between the sealing position and the unsealing position, so as to open and close the first inner port 2021 and the second inner port 2031. When the cleaning robot falls to the ground, the convex part moves to the matching position along with the wheel arm, the cover plate 221 is located at the unsealing position, and the cleaning robot can carry out normal ground washing operation; when the cleaning robot lifts off the ground, the protrusion 613 moves to the separated position along with the wheel arm 610, and the cover 221 is in the sealing position, thereby preventing the sewage from overflowing from the suction channel 202 and the air outlet channel 203. Therefore, the cleaning robot 1 provided by the present invention is very convenient to switch the cover plate 221 between the sealing position and the unsealing position.

At least a portion of the bottom wall of the box 210 is recessed to form a receiving slot 204. The first outer port 2022 of the air suction channel 202 is disposed on the wall of the receiving slot 204 and the receiving slot 204 is connected, and the first inner port 2021 of the air suction channel 202 is connected to the receiving cavity 201. The second inner port 2031 of the air outlet channel 203 is communicated with the accommodating chamber 201, and the second outer port 2032 of the air outlet channel 203 is communicated with the external environment. A sealing ring 250 is disposed around the periphery of the receiving groove 204 and has a closed shape. When the storage box 200 is mounted in the first groove 101, the sealing ring 250 abuts against the mounting surface of the first groove 101 to seal the gap between the storage box 200 and the mounting surface of the first groove 101, so as to reduce the amount of air in the external environment entering the housing groove 204, thereby improving the effect of the fan assembly on sucking dirt; that is, the effect of sucking the contaminants by the cleaning robot 1 can be improved.

The storage box 200 further has a first liquid channel 205 and a liquid outlet portion 206 respectively communicating the first liquid channel 205 with the external environment, the first liquid channel 205 is isolated from the storage cavity 201, and the first liquid channel 205 is used for communicating with the liquid supply mechanism. The containing box 200 is integrated with a first liquid channel 205 which can be communicated with the liquid supply mechanism and can output liquid to the outside through a liquid outlet 206; that is, the storage box 200 is integrated with a function of receiving and spraying the cleaning liquid, so that the cleaning robot 1 provided by the present invention does not need to be additionally provided with a spray pipe, which is advantageous for miniaturization of the cleaning robot.

In addition, the cleaning robot 1 provided by the embodiment of the present invention further includes a wiper strip 800. The wiper strip 800 is installed at the bottom of the robot main body 100 and disposed near the cleaning roller 300, and the wiper strip 800 is in interference contact with the floor surface when the cleaning robot 1 falls to the floor. Then, an almost airtight negative pressure space is enclosed among the wiper strip 800, the cleaning roller 300 and the robot main body 100, and in the process that the cleaning robot 1 advances towards the side of the cleaning roller 300 departing from the wiper strip 800, the wiper strip 800 forms a shelter behind the cleaning roller 300, which can prevent the outside air from entering the space, thereby improving the negative pressure adsorption effect of the cleaning robot 1 on the ground dirt.
