The sealing member 232 is embedded between the outer wall of the push rod 231 and the inner wall of the through hole, and is used for sealing the connection between the push rod 231 and the tank 210, so as to avoid overflow of sewage from the connection. In other embodiments of the present invention, the push rod 231 may be disposed on a side of the first inner port (or the second inner port) facing away from the boss 2115, but in this embodiment, the push rod 231 is preferably disposed between the boss 2115, i.e., the connecting end and the first inner port 2021, by a smaller pushing distance when the push rod 231 is disposed between the connecting end of the cover plate 221 (the connecting end of the cover plate and the case) and the first inner port 2021 (or the second inner port). Preferably, the push rod 231 is disposed near the connection end of the cover plate, and it is more effective to lift the other end of the cover plate 221. In addition, it should be noted that the through hole penetrates the boss 2115 and the bottom wall of the case 210, and the boss 2115 is formed by the concave bottom wall of the case 211 in the present embodiment, so that the through hole actually penetrates the bottom wall of the case 210 in the present embodiment, and of course, in other embodiments of the present invention, the boss 2115 may not be formed by the concave bottom wall of the case 210, but be a solid structure, and in this case, the boss 2115 and the bottom wall of the case 210 are independent, and the through hole actually penetrates the boss 2115 and the bottom wall of the case 210 respectively.

In the present embodiment, the cleaning robot 1 implements driving of the push rod 231 from the first position to the second position by the driving wheel assembly 600. For ease of understanding, the specific structure of the drive wheel assembly 600 will be described. Referring specifically to fig. 4, in conjunction with other figures, the drive wheel assembly 600 includes a wheel arm 610 rotatably mounted to the robot body 100 and extending at least partially out of the bottom of the robot body 100. Specifically, the wheel arm 610 includes a base arm 611 and a drive wheel 612 rotatably mounted to the base arm 611. One end of the base arm 611, which is far from the driving wheel 612, is rotatably mounted inside the robot body 100 through a rotating shaft, and two ends of a tension spring, not shown, are respectively connected with the base arm 611 and the robot body 100, so that the wheel arm 610 can be kept stable relative to the robot body 100 in a stationary state. The bottom of the robot body 100 is disposed at a position corresponding to the driving wheel 612 in a clearance manner, so that the bottom of the driving wheel 612 at least partially extends out of the robot body 100. When the cleaning robot 1 is landed, the free end of the wheel arm 610 rotates clockwise in the drawing with respect to the robot body 100, that is, the robot body 100 sinks a set distance with respect to the free end of the wheel arm 610, whereas when the cleaning robot 1 is separated from the floor, the free end of the wheel arm 610 rotates counterclockwise in the drawing with respect to the robot body 100, that is, the robot body 100 lifts a set distance with respect to the free end of the wheel arm 610.

The free end of the arm 610 is provided with a protruding part 613, and the protruding part 613 is specifically provided on the base arm 611 and can have a separated position and a matched position along with the movement of the arm 610, wherein the push rod 231 is in the first position in the separated position, and the protruding part 613 drives the push rod 231 to the second position by driving the bottom of the push rod 231 in the matched position. Wherein the state of the wheel arm 610 when the protruding portion 613 is located at the separated position is more protruded from the bottom of the robot body 100 than the state of the wheel arm 610 when the protruding portion 613 is located at the engaged position.

Further, to facilitate the installation of the wheel arm 610, the driving wheel assembly 600 further includes a wheel bracket 620, wherein the wheel bracket 620 is fixed inside the housing 110 and accommodates the base arm 611 and the top portion of the driving wheel 612, so as to avoid the rotation of the driving wheel 612 from interfering with the circuits, the pipes, etc. in the robot main body 100. One end of the arm 610 is rotatably mounted on the wheel bracket 620, and the wheel bracket 620 is provided with a clearance portion through which the protrusion 613 travels, so that the protrusion 613 can have the engaging position and the disengaging position according to the movement of the arm 610.

Further, in consideration of a certain gap between the wheel arm 610 and the push rod 231, if the push rod 231 is pushed by the protrusion 613, the protrusion 613 needs to be designed to be long enough, which makes the removal and installation of the driving wheel assembly 600 very difficult, and the cover driving assembly 230 further includes the rotating member 233 to overcome the defect. Specifically, referring to fig. 4, the rotating member 233 has a plate-like structure, which is disposed below the push rod 231 and the through hole, and one end of the rotating member 233 is rotatably mounted in the robot main body 100, and the other end is supported on the protruding portion 613. When the protruding portion 613 is located at the mating position, the protruding portion 613 drives the rotating member 233 to rotate, so that the rotating member 233 pushes the push rod 231 to the second position, and the cover 221 is driven to move to the unsealing position. It should be noted that the connection relationship between the push rod 231 and the rotating member 233 and the protruding portion 613 is not particularly limited when the push rod 231 is located at the first position, the push rod 231 may be supported by the case 210, for example, a supporting groove is formed on the boss 2115, a supporting flange is formed on the outer wall of the push rod 231, and is supported by the supporting groove, at this time, the push rod 231 and the rotating member 233 may be connected, at this time, the push rod 231 may be supported by the sealing member 232, at this time, the push rod 231 and the rotating member 233 may be connected, at this time, the push rod 231 and the rotating member 233 may be supported by each other, and in this case, there is always a physical connection relationship, such as abutting, hinging, sliding connection, etc., between the push rod 231 and the rotating member 233.

A second hall element (not shown) is mounted to the housing 110 and is disposed near the bottom of the case 210, and is used to cooperate with the second magnet to detect whether the storage box 200 is in place, and when the storage box 200 is in place, the second hall element detects that it is in place and then sends a signal to the controller, and the controller controls the floor cleaning robot to switch to a mode state in which cleaning operation is possible according to the signal, otherwise, to switch to a mode state in which cleaning operation is impossible.

Further, in some embodiments, to facilitate the user to extract the storage box 200, the storage box 200 further includes a handle. Specifically, referring to fig. 3 and 6, in conjunction with other figures, the handle 290 is generally arcuate, and two ends thereof are rotatably mounted on top of or on top of the side walls 2112 of the case 210, respectively, and are rotatable to be perpendicular or parallel to the top wall of the case 210, so that a user can take the storage case 200 by extracting the middle region of the handle 290. Preferably, a handle accommodating groove (not shown) adapted to the handle 290 is provided on the outer surface of the top wall of the case 210, so that when the accommodating case 200 is accommodated in the first groove 101, the handle 290 can be rotated into the handle accommodating groove, so as to avoid the effect that the opening of the first flip cover 120 covers the first groove 101 due to the protrusion of the handle 290 from the surface of the case 210.

Further, the structure of the handle 290 is further improved to enhance the fixing effect of the storage box 200 in the height direction relative to the robot main body 100 when the storage box is accommodated in the first groove 101. Specifically, referring to fig. 14, which is a partially enlarged schematic view of fig. 6B, in combination with other drawings, an end of the handle 290 is provided with a limiting groove 291 on an end surface facing away from the center of the end, the limiting groove 291 extends along a preset direction, a first end 2911 of the limiting groove 291 is closed, and a second end 2912 of the limiting groove 291 starts from the first end 2911 and penetrates through the end of the handle 290 along the preset direction. Accordingly, the robot main body 100 is provided with a stopper column (not shown) at a position facing the stopper groove 291, the stopper column being adapted to cooperate with the stopper groove 291 to restrict the degree of freedom of movement of the storage box 200 in the height direction of the cleaning robot 1. Specifically, in the process that 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 post slides from the second end 2912 to the first end 2911 of the limiting groove 291 relative to the handle 290 and constrains the freedom of movement of the storage box 200 along the height direction of the cleaning robot 1, and in the process that the handle 290 rotates from the second preset position to the first preset position, the limiting post is separated from the limiting groove 271 from the second end 2912, so that the user can freely extract the storage box 200. The first preset position is a position where the handle 290 is perpendicular to the top wall of the box 210, and 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 axis of the first end 2911 is collinear with the axis of rotation of the handle 290, and the second end 2912 extends in a predetermined direction and extends 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 the end, where the predetermined direction is a rotation direction of the handle 290 from the first predetermined position to the second predetermined position. It should be noted that, the setting of the limiting groove 291 and the limiting post can also remind the user that the holding box 200 can be lifted only by rotating the lifting handle to the vertical position, so as to ensure the overall balance of the holding box 200 in the process of separating from the first groove 101.

Further, considering that the cleaning roller 300 is in contact with the floor while the cleaning robot 1 is landed and the robot body 100 is higher than the floor, during the traveling of the cleaning robot 1, the rear of the cleaning roller 300 is free from the shielding, and the air behind the cleaning roller 300 enters the suction channel 202 through the gap between the cleaning roller 300 and the robot body 100, which reduces the suction effect of the fan assembly 700 on the floor dirt, the cleaning robot 1 further includes the scraping bar 800 to overcome the disadvantage. Specifically, referring to fig. 15, which is a partially enlarged schematic view of fig. 4C, and in combination with other drawings, the wiper strip 800 extends in a direction parallel to the axial direction of the cleaning roller 300 as a whole, is mounted at the bottom of the robot body 100 and is disposed near the cleaning roller 300, and when the cleaning robot 1 lands, the wiper strip 800 contacts the ground, and the wiper strip 800 is located behind the cleaning roller 300 in the advancing direction of the cleaning robot 1. The scraping strip 800 is used for forming a shielding object 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 outside air from entering the space, thereby improving the negative pressure adsorption effect of the cleaning robot on ground dirt and dirt on the cleaning roller 300. The scraping bar 800 is also used for recycling dirt which is not cleaned in time due to the first turnover of the cleaning roller 300 and dirt which is not adsorbed to the accommodating cavity 201 due to the fan assembly 700 in time, so that the cleaning roller 300 can collect the dirt recycled by the scraping bar 800 into the accommodating cavity 201 through continuous turnover and continuous adsorption of the fan assembly 700.

Further, the scraping strip 800 includes a fixing portion 810 and a connecting portion 820, wherein the fixing portion 810 is mounted 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 contact with the floor surface when the cleaning robot 1 is landed.

Further, at least part of the scraping strip 800 contacts with the cleaning roller 300, preferably, the fixing portion 810 is at least partially attached to the outer end of the lint 320 of the cleaning roller 300, that is, at least part of the scraping strip 800 is attached to the circumferential surface of the cleaning roller 300, so that, on one hand, the gap between the scraping strip 800 and the cleaning roller 300 is reduced, that is, the volume of the negative pressure space is reduced, and thus the negative pressure adsorption effect of the fan assembly 700 is improved, and on the other hand, the friction force of the garbage with larger volume between the cleaning roller 300 and the scraping strip 800 is properly increased, and thus the garbage with larger volume is facilitated to climb.

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

The box 210 includes a box 211, a box cover 212 and a box sealing ring 213. The case cover 212 is covered on the case 211 and encloses a containing cavity 201 with the case 211, and the case sealing ring 213 is arranged at the junction of the case cover 212 and the case 211 and seals the junction of the case cover 212 and the case 211. Then, even if the cleaning robot 1 is tilted or inverted, the liquid in the receiving chamber 201 is prevented from leaking out by the case seal 213. The accommodating box 200 can effectively avoid the disadvantage that the liquid in the accommodating cavity 201 seeps outwards, and the cleaning robot 1 comprising the accommodating box 200 can effectively avoid the disadvantage that the liquid in the accommodating cavity 201 seeps outwards.

The box 210 is provided with an air suction channel 202 respectively communicating with the storage cavity 201 and the external environment of the box 210, and an air outlet channel 203 respectively communicating with the storage cavity 201 and the external environment of the box 210. 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, the cover plate seals the air suction channel and the air outlet channel in the sealing position, and the cover plate unseals the air suction channel and the air outlet channel in the unsealing position. Therefore, after the cleaning robot 1 provided by the invention stops working, the accommodating box 200 can cover the air suction channel 202 and the air outlet channel 203 by making the cover plate 221 at the sealing position, thereby preventing sewage from overflowing from the air suction channel and the air outlet channel, and avoiding the defect that sewage overflows from the air suction channel 202 and/or the air outlet channel 203 due to slight inclination of the cleaning robot 1 when a user takes the cleaning robot 1.

The cleaning robot 1 uses the characteristic that the wheel arm 610 rotates relatively to the robot main body 100 when the cleaning robot is lifted off or falls to the ground, and the protruding portion 613 provided on the wheel arm 610 drives the push rod 231 in the cover plate driving assembly 230 to move between the first position and the second position, so as to drive the cover plate 221 to move between the sealing position and the unsealing position, thereby realizing the opening and closing of the first inner end 2021 and the second inner end 2031. When the cleaning robot lands, the protruding part moves to the matching position along with the wheel arm, the cover plate 221 is in the unsealing position, the cleaning robot can perform normal land washing operation, and when the cleaning robot leaves the ground, the protruding part 613 moves to the separating position along with the wheel arm 610, the cover plate 221 is in the sealing position, so that sewage is prevented from overflowing from the air suction channel 202 and the air outlet channel 203. The cleaning robot 1 provided by the invention is very convenient in the process of switching the cover plate 221 between the sealing position and the unsealing position.

Wherein, the bottom wall of the case 210 is at least partially concave to form a receiving groove 204. The first outer port 2022 of the air suction channel 202 is disposed on the groove wall of the accommodating groove 204 and is communicated with the accommodating groove 204, and the first inner port 2021 of the air suction channel 202 is communicated with the accommodating cavity 201. The second inner port 2031 of the air outlet channel 203 communicates with the storage cavity 201, and the second outer port 2032 of the air outlet channel 203 communicates with the external environment. A sealing ring 250 is provided at the periphery of the receiving groove 204 to have a closed shape. When the accommodating box 200 is mounted in the first groove 101, the sealing ring 250 will abut against the mounting surface of the first groove 101 to seal the gap between the accommodating box 200 and the mounting surface of the first groove 101, so as to reduce the amount of air entering the accommodating groove 204 in the external environment, thereby improving the dirt sucking effect of the fan assembly, that is, the dirt sucking effect of the cleaning robot 1.

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

In addition, the cleaning robot 1 provided by the embodiment of the invention further comprises a scraping bar 800. The wiper strip 800 is installed at the bottom of the robot body 100 and is disposed near the cleaning roller 300, and the wiper strip 800 contacts the floor when the cleaning robot 1 lands. Then, a nearly airtight negative pressure space is defined between the scraping strip 800, the cleaning roller 300 and the robot main body 100, and in the process that the cleaning robot 1 advances towards one side of the cleaning roller 300 away from the scraping strip 800, the scraping strip 800 forms a shielding object behind the cleaning roller 300, which can prevent the outside air from entering the space, so as to further promote the negative pressure adsorption effect of the cleaning robot 1 on the ground dirt.

Based on the same inventive concept, the present invention also provides a storage box having the same structure as the storage box 200 in the above embodiment. The specific structure and beneficial effects of the storage box are the same as those of the storage box 200 in the above embodiment, and will not be described herein.
