When the third snap-fit ​​portion disengages from the fourth snap-fit ​​portion, the second flip cover 130 opens the opening, allowing the user to remove the liquid storage tank 500 from the second groove 102. Optionally, the first flip cover 120 and the second flip cover 130 open in opposite directions, and during their opening process, the first flip cover 120 and the second flip cover 130 gradually move towards the center of the top of the housing 110.

[0059] For the aforementioned storage box 200, please refer to Figures 5 to 7The diagram shows perspective views of the storage box 200 in two directions with the lid open, and in one direction with the lid closed. The storage box 200 includes a box body 210, a lid assembly 220, a lid drive assembly 230, and a locking assembly 240. The box body 210 has a storage cavity 201 for storing waste. The box body 210 also has a suction channel 202 and an exhaust channel 203. The suction channel 202 communicates with both the external environment of the box body 210 and the storage cavity 201, while the exhaust channel 203 communicates with both the storage cavity 201 and the external environment of the box body 210. The cover assembly 220 is housed in the receiving cavity 201 and is movable between a sealed position and an unsealed position. In the sealed position, it seals the air intake channel 202 and the air outlet channel 203; in the unsealed position, it unseales the air intake channel 202 and the air outlet channel 203. The cover drive assembly 230 drives the cover assembly 220 from the sealed position to the unsealed position. The locking assembly 240 is connected to both the cover assembly 220 and the housing 210, and is used to maintain the cover assembly 220 in the sealed position. For ease of understanding, the specific structures of the housing 210, the cover assembly 220, the cover drive assembly 230, and the locking assembly 240 will be described in detail below. Next, the specific structure of the housing 210 will be described in detail.

[0060] For details regarding the aforementioned housing 210, please refer to [link / reference needed]. Figure 5 and Figure 6 The box body 210 includes a box 211 and a lid 212. The box 211 is a box-shaped structure without a top, including a bottom wall 2111 and side walls 2112 extending from the edge of the bottom wall 2111. The lid 212 covers the opening of the box 211 and together with the box 211, forms the aforementioned storage cavity 201. That is, the bottom wall 2111 constitutes the bottom wall of the box body 210, the side walls 2112 constitute the side walls of the box body 210, and the lid 212 constitutes the top wall of the box body 210. In this embodiment, the lid 212 has a first connecting part 2121 and a second connecting part 2122. The first connecting part 2121 is rotatably connected to the box 211, and the second connecting part 2122 is connected to the box 211 by a snap-fit ​​connection, so that the lid 212 tightly covers the box 211. Users can open the storage cavity 201 by separating the second connecting part 2122 from the box 211, and then clean the dirt in the storage cavity 201. Optionally, the box lid 212 is a flat cuboid shape, and the first connecting part 2121 and the second connecting part 2122 are respectively disposed on opposite side surfaces of the box lid 212; it is understood that in other embodiments of the present invention, the first connecting part 2121 and the second connecting part 2122 may also be disposed on adjacent side surfaces of the box lid 212.

[0061] Furthermore, to enhance the sealing effect between the lid 212 and the box 211, thereby preventing sewage in the storage cavity 201 from overflowing from the connection between the lid 212 and the box 211, the storage box 200 also includes a box body sealing ring 213. This sealing ring 213 is located at the connection between the lid 212 and the box 211 and seals the connection. It should be noted that the sealing ring 213 can be a sealing rubber ring or a sealing layer formed by sealing adhesive, such as UV-cured adhesive.

[0062] For details, please continue reading Figure 5 The lid 212 has a mounting groove 2123 formed on the side facing the box 211, which is adapted to the top of the box 211. The top of the box 211 is inserted into the mounting groove 2123, and the box sealing ring 213 is embedded between the top of the box 211 and the groove wall of the mounting groove 2123. In this embodiment, the box sealing ring 213 is fixed to the top surface of the box 211, that is, the side facing the lid 212, and extends along the contour of the top surface of the box 211 in a closed ring shape; when the lid 212 covers the box 211, the box sealing ring 213 seals the connection between the two. It is understood that the location of the box sealing ring 213 is not limited to the top surface of the box 211; it can also be located in other positions, as long as it can seal the connection between the box 211 and the lid 212. For example, in some other embodiments of the present invention, the box sealing ring 213 is fixed to the outer surface of the top of the box 211 and extends along the contour of the top surface of the box 211 in a closed ring shape. For another example, in some other embodiments of the present invention, the box sealing ring 213 is fixed to the inner surface of the top of the box 211 and extends along the contour of the top surface of the box 211 in a closed ring shape. For yet another example, in some other embodiments of the present invention, the box sealing ring 213 is fixed to the groove wall of the mounting groove 2123 and extends along the contour of the top surface of the box 211 in a closed ring shape.

[0063] Please combine Figure 6 and Figure 7The housing 210 is also provided with an air intake channel 202 and an air outlet channel 203. The air intake channel 202 has a first outer port 2022 and a first inner port 2021. The first outer port 2022 penetrates the bottom wall 2111 of the housing 211 and communicates with the external environment. This first outer port 2022 is the suction end of the housing 210 during the process of collecting dirt, and it corresponds to the cleaning roller 300 mentioned above. The first inner port 2021 is located between the bottom wall of the housing 211 and the lid 212 and communicates with the storage cavity 201. The air outlet channel 203 has a second inner port 2031 and a second outer port 2032. The second inner port 2031 is located between the bottom wall 2111 of the housing 211 and the lid 212 and communicates with the storage cavity 201. The second outer port 2032 communicates with the external environment and is the outlet for the airflow within the storage cavity 201. In this embodiment, the box 211 is formed with a suction section 2113 and a discharge section 2114 housed in the storage cavity 201. The suction section 2113 is fixed to the bottom wall of the box 211. One end of the suction channel 202 passes through the end of the suction section 2113 away from the bottom wall 2111, forming the aforementioned first inner port 2021, and the other end passes through the bottom wall 2111, forming the first outer port 2022. The discharge section 2114 is also fixed to the bottom wall 2111 of the box 211. One end of the discharge channel 203 passes through the end of the discharge section 2114 away from the bottom wall 2111, forming the second inner port 2031, and the other end passes through the bottom wall 2111, forming the second outer port 2032. Optionally, the second inner port 2031 includes a plurality of small ventilation holes to allow airflow while preventing larger debris from passing through. Optionally, both the first inner port 2021 and the second inner port 2031 protrude from the bottom wall 2111 of the box 211 and are flush with each other. Preferably, the cross-sectional profile of the suction channel 202 gradually narrows from the first outer port 2022 to the first inner port 2021; thus, the portion of the suction channel 202 near the first outer port relative to the bottom wall of the box 210 will form an obtuse angle, which can, to a certain extent, allow airflow to enter the suction channel 202 more smoothly from the outside of the box 210, reducing airflow loss caused by excessive turning (i.e., excessive turning angle). In addition, the specific location of the second outer port 2032 depends on the layout of the components inside the robot body 100; in other embodiments of the present invention, the second outer port 2032 may also be located on the side wall 2112 of the box 211.

[0064] Next, the cover plate assembly 220 will be described in detail.

[0065] For cover plate assembly 220, please refer to the following document. Figure 5 and Figure 6In conjunction with other accompanying drawings, the cover assembly 220 includes a cover 221, which is a flat, plate-like structure housed in a receiving cavity 201. The cover 221 is movable between a sealed position and an unsealed position to seal or unseal the aforementioned air intake channel 202 and air outlet channel 203. Specifically, in conjunction with... Figure 12 The cleaning robot 1 also includes a fan assembly 700, whose air inlet 710 is connected to the second external port 2032. Preferably, a sealing ring is provided at the connection between the second external port 2032 and the air inlet 710 to prevent air leakage. At the sealed position, the cover plate 221 completely covers and seals the first inner port 2021 and the second inner port 2031. At this time, the sewage in the receiving cavity 201 will not overflow to the outside of the box 210 through the suction channel 202 and the air outlet channel 203, thereby avoiding safety accidents caused by sewage overflow. At the unsealed position, the cover plate 221 unseals the first inner port 2021 and the second inner port 2031, and the fan assembly 700 can draw air from the box 210 to make the first external port 2022 a negative pressure state, which is convenient for sucking up dirt on the ground and the cleaning roller 300.

[0066] In this embodiment, the cover plate 221 is rotatably connected to the box body 210, meaning that the cover plate 221 can rotate between a sealed position and an unsealed position. Specifically, the bottom wall and side wall portions of the box 211 are recessed to form a boss 2115. One end of the cover plate 221 is rotatably connected to the upper surface of the boss 2115, and the other end can pivot around this end to seal or unseal the first inner port 2021 and the second inner port 2031. Optionally, if the direction from the first inner port 2021 to the second inner port 2031 is parallel to the rotation axis X of the cover plate 221, then the free end of the cover plate 221 can move up and down along the direction shown in the figure to simultaneously 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 can also be designed to rotate around the Y-axis, Z-axis, or other directions shown in the figure. Preferably, the first inner port 2021 and the second inner port 2031 are flush, so that when the cover plate 221 is in the sealed position, one end of it is supported by the boss 2115, and the other end is supported 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 in the figure), such as a rubber sheet or a sealing ring, is fixed to one end of the cover plate 221 facing the first inner port 2021 and the second inner port 2031, to seal the connection between the cover plate 221 and the first inner port 2021 and the second inner port 2031 respectively. It is understood that in other embodiments of the present invention, the cover plate 221 may also be connected to the housing 210 in other ways, such as a sliding connection, as long as it can move back and forth between the sealed position and the unsealed position to seal or unseal the air intake channel 202 and the air outlet channel 203, and is not limited to the rotational connection in this embodiment.

[0067] Furthermore, to prevent sewage, garbage, and other contaminants from entering the storage cavity 201 directly from the suction channel 202 during the process of the fan assembly 700 drawing air from the storage box 200, and from moving into the robot body 100 via the second external port 2032, thereby causing a safety accident to the floor cleaning robot 1, the aforementioned cover assembly 220 also includes a partition 222. Specifically, please refer to Figure 5 and other accompanying drawings. One end of the partition 222 is fixed to the cover plate 221, and the other end extends towards the bottom wall 2111 of the box 211. The partition 222 is at least partially located between the first inner port 2021 and the second inner port 2031. Sewage, garbage, and other contaminants entering the storage cavity 201 from the suction channel 202 will fall into the bottom of the storage cavity 201 due to the obstruction of the partition 222. The airflow will pass over the edge (such as the bottom or side) of the partition 222 and flow to the fan assembly 700 via the exhaust channel 203. It is worth mentioning that, in addition to blocking contaminants, the partition 222 can also accelerate the airflow within the storage cavity 201, thereby enhancing the adsorption force of the storage box 200 on ground contaminants and contaminants on the cleaning roller. Preferably, the exhaust channel 203 is also provided with a filter element to prevent contaminants from passing through while allowing airflow; this element is preferably filter cotton.

[0068] The cover plate drive assembly 230 will now be described in detail.

[0069] For cover plate drive assembly 230, please refer to Figure 5 In conjunction with other accompanying drawings, the cover plate drive assembly 230 is mounted on the housing 211 of the enclosure, and is used to drive the cover plate 221 to move from the self-sealing position (not shown in the figure) to... Figure 5The unsealing position is shown. Specifically, the cover drive assembly 230 includes a push rod 231 and a seal 232. The push rod 231 is located below the cover 221, with its other end extending through the bottom wall of the housing and out of the housing. The push rod is movable relative to the housing and can move between a first position and a second position. In the first position, the cover 221 is in a sealed position, i.e., the free end of the cover 221 is supported by the first inner port 2021 and the second inner port 2031. In the second position, the push rod 231 pushes the cover 221 to the unsealing position, and the push rod 231 is closer to the top wall of the housing 210 in the second position than in the first position. In this embodiment, the housing 210 is formed with a through boss 2115 and a bottom wall 2111 of the box 211, and a through hole (not shown in the figure) communicating with the storage cavity 201. The push rod 231 is disposed in the through hole and can pass through the through hole at least partially to move between a first position and a second position, thereby pushing the cover plate 221. It is understood that the installation method of the push rod 231 is not limited to the above method. For example, in some other embodiments of the present invention, it can also be rotatably installed on the housing 210, ensuring that it can push the cover plate 221 to the unsealed position. It is worth mentioning that the process of the cover plate 221 moving from the unsealed position to the sealed position can be reset under the action of gravity; or it can be reset by the pulling action of the push rod 231. In this case, the push rod 231 and the cover plate 221 have an actual connection relationship. The present invention does not specifically limit how the cover plate 221 is reset. A sealing element 232 is embedded between the outer wall of the push rod 231 and the inner wall of the through hole, and is used to seal the connection between the push rod 231 and the housing 210, thereby preventing sewage from overflowing from the connection. In some other embodiments of the present invention, the push rod 231 can also be disposed on the side of the first inner port (or second inner port) away from the boss 2115; however, compared with this, disposing the push rod 231 between the connecting end of the cover plate 221 (the end where the cover plate connects to the housing, hereinafter referred to as the connecting end) and the first inner port 2021 (or the second inner port) allows the push rod 231 to push the cover plate 221 open to a larger angle with a smaller pushing distance. Therefore, in this embodiment, it is preferable to dispose of the push rod 231 on the boss 2115, that is, between the connecting end and the first inner port 2021. Preferably, the push rod 231 is disposed close to the connecting end of the cover plate, which has a better effect on lifting the other end of the cover plate 221. Furthermore, it is worth mentioning that the aforementioned through hole penetrates the boss 2115 and the bottom wall of the housing 210. Since the boss 2115 is formed by the indentation of the bottom wall of the housing 211 in this embodiment, the through hole actually penetrates the bottom wall of the housing 210 in this embodiment. Of course, in other embodiments of the present invention, the boss 2115 may not be formed by the indentation of the bottom wall of the housing 210, but may be a solid structure. In this case, the boss 2115 and the bottom wall of the housing 210 are independent of each other, and the aforementioned through hole actually penetrates the boss 2115 and the bottom wall of the housing 210 respectively.

[0070] In this embodiment, the cleaning robot 1 drives the push rod 231 from the first position to the second position via the drive wheel assembly 600. For ease of understanding, the specific structure of the drive wheel assembly 600 will be described below. Please refer to the following for details. Figure 4 In conjunction with other accompanying drawings, the drive wheel assembly 600 includes a wheel arm 610, which is rotatably mounted to the robot body 100 and at least partially extends 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 on the base arm 611. The end of the base arm 611 away from the drive wheel 612 is rotatably mounted inside the robot body 100 via a pivot. A tension spring (not shown) is connected at both ends to the base arm 611 and the robot body 100, thereby allowing the wheel arm 610 to remain stable relative to the robot body 100 when stationary. The bottom of the robot body 100 is provided with an opening at the corresponding drive wheel 612, allowing at least a partial extension of the bottom of the drive wheel 612 out of the robot body 100. When the cleaning robot 1 lands, the free end of the wheel arm 610 rotates clockwise relative to the robot body 100 as shown in the figure, which means that the robot body 100 sinks a set distance relative to the free end of the wheel arm 610; conversely, when the cleaning robot 1 leaves the ground, the free end of the wheel arm 610 rotates counterclockwise relative to the robot body 100 as shown in the figure, which means that the robot body 100 rises a set distance relative to the free end of the wheel arm 610.

[0071] The free end of the wheel arm 610 is provided with a protrusion 613, which is specifically provided on the base arm 611 and can have a separated position and an engaged position as the wheel arm 610 moves. In the separated position, the push rod 231 is in the first position mentioned above. In the engaged position, the protrusion 613 drives the push rod 231 to the second position by driving the bottom of the push rod 231. In the state where the protrusion 613 is in the separated position, the wheel arm 610 extends further out of the bottom of the robot body 100 than the state where the protrusion 613 is in the engaged position.

[0072] Furthermore, to facilitate the installation of the wheel arm 610, the drive wheel assembly 600 also includes a wheel bracket 620. The wheel bracket 620 is fixed inside the housing 110 and accommodates the top portion of the base arm 611 and the drive wheel 612 to prevent the rotation of the drive wheel 612 from interfering with the wiring, pipes, etc., inside the robot body 100. One end of the aforementioned wheel arm 610 is rotatably mounted on the wheel bracket 620. The wheel bracket 620 is provided with a clearance portion for the aforementioned protrusion 613 to pass through, so that the protrusion 613 can have the aforementioned mating position and disengagement position as the wheel arm 610 moves.

[0073] Furthermore, considering the certain gap between the wheel arm 610 and the push rod 231, if the protrusion 613 directly contacts and pushes the push rod 231, the protrusion 613 needs to be designed to be long enough. This would make the disassembly and installation of the drive wheel assembly 600 extremely difficult. To overcome this drawback, the aforementioned cover plate drive assembly 230 also includes a rotating component 233. For details, please refer to [further details]. Figure 4 The rotating component 233 is a plate-shaped structure located below the push rod 231 and the through hole. One end of the rotating component 233 is rotatably mounted in the robot body 100, and the other end is supported by the protrusion 613. When the protrusion 613 is in the mating position, the protrusion 613 drives the rotating component 233 to rotate, thereby causing the rotating component 233 to push the push rod 231 to the second position, thus driving the cover plate 221 to move to the unsealed position. It is worth mentioning that the present invention does not specifically limit the connection relationship between the push rod 231, the rotating member 233, and the protrusion 613 when the push rod 231 is in the first position. When the push rod 231 is in the first position, the push rod 231 can be supported by the housing 210, such as the boss 2115 forming a support groove, and the outer wall of the push rod 231 forming a support flange, which supports the support groove. In this case, the push rod 231 and the rotating member 233 can be connected or not. The push rod 231 can also be supported by the aforementioned sealing member 232. In this case, the push rod 231 and the rotating member 233 can be connected or not. The push rod 231 can also be supported by the rotating member 233. In this case, there is always a physical connection between the push rod 231 and the rotating member 233, such as abutment, hinge, sliding connection, etc.

[0074] The locking component 240 will now be described in detail.

[0075] For the aforementioned locking component 240, please refer to... Figure 5 and Figure 6The locking assembly 240 is connected to both the cover assembly 220 and the housing 210, and is used to maintain the cover 221 in the aforementioned sealed position. In this embodiment, the locking assembly 240 includes a first magnetic element 241 and a second magnetic element 242. The first magnetic element 241 is mounted on the cover 221, and the second magnetic element 242 is mounted on the housing 210 and disposed near the first inner port 2021 or the second inner port 2031; the first magnetic element 241 and the second magnetic element 242 are used to attract each other to maintain the cover 221 in the sealed position. Of course, the first magnetic element 241 can also be disposed on the partition 222. Furthermore, it should be understood that in other embodiments of the present invention, the locking assembly 240 may also have other structural forms, as long as it can maintain the cover plate 221 in a sealed position; for example, in some other embodiments of the present invention, the locking assembly 240 includes a compression spring disposed between the cover plate 221 and the top wall of the housing 210, with one end abutting against the cover plate 221 and the other end abutting against the top wall of the housing 210; as another example, in some other embodiments of the present invention, the locking assembly 240 includes a torsion spring sleeved on the connecting link of the pivotally connected cover plate 221. On the pivot of the connector and housing 210, one end abuts against the cover plate 221 and the other end abuts against the housing 210; for example, in other embodiments of the present invention, the locking assembly 240 may also include at least two of the above-mentioned paired first magnetic element 241 and second magnetic element 242, compression spring and torsion spring, thereby enhancing the reset effect of the cover plate 221 during the process of moving from the unsealed position to the sealed position, so as to overcome the deficiency that the cover plate 221 cannot be smoothly reset to the sealed position in some cases due to the push rod 231 getting stuck during the downward movement.

[0076] For the cleaning roller 300 mentioned above, please refer to Figure 11 It shows an exploded view of the cleaning roller 300, and in conjunction with Figures 4 to 6 The cleaning roller 300 is mounted on the housing 110, which is located below the storage box 200. The bottom wall of the first groove 101 has a through-hole groove at the position corresponding to the cleaning roller 300. The cleaning roller 300 passes through the through-hole groove at least partially and extends into the first groove 101. The bottom wall 2111 of the box 210 is at least partially recessed to form a receiving groove 204 extending along a set direction P. The top of the circumferential surface of the cleaning roller 300 is received in the receiving groove 204 and is disposed close to the groove wall of the receiving groove 204. Optionally, the set direction P is parallel to the axial direction of the cleaning roller 300; preferably, the groove wall of the receiving groove 204 is arc-shaped in a section perpendicular to the set direction P, and the circumferential surface of the cleaning roller 300 is in contact with the groove wall of the receiving groove 204. In this embodiment, the cleaning roller 300 includes a rotating shaft 310 and a velvet cloth 320 sleeved on the rotating shaft 310; wherein the rotating shaft 310 is rotatably mounted on the robot body 100.

[0077] For the aforementioned roller power assembly, please refer to Figure 12 and Figure 13 The diagram shows a three-dimensional view of the cleaning robot 1 after concealing the storage box 200, liquid tank 500, and part of the shell 110, as well as a partially exploded view of the roller power assembly 400. The roller power assembly 400 includes a base 410, a rotating mechanism 420, and an output terminal 430. The base 410 is installed inside the robot body 100 and is used to mount the rotating mechanism 420. The rotating mechanism 420 provides rotational output through an output shaft (not shown). The output terminal 430 is fixed to the output shaft and engages with a mating part (not shown) on the end of the rotating shaft 310 of the cleaning roller 300 to achieve circumferential fixation, thereby driving the cleaning roller 300 to rotate and clean the floor. In this embodiment, the output terminal 430 is cross-shaped, and the mating part on the rotating shaft 310 is a cross-shaped groove.

[0078] Furthermore, to facilitate user assembly and disassembly of the cleaning roller 300 without direct hand contact, the cleaning robot 1 also includes a roller handle 330. For details, please refer back to the previous section. Figure 11 and Figure 12 In conjunction with other accompanying drawings, the roller handle 330 is located at the end of the cleaning roller 300 furthest from the output terminal 430 and is snapped into place with the robot body 100. The end of the cleaning roller 300 furthest from the output terminal 430 is rotatably mounted to the roller handle 330 via a bearing 340. Therefore, users can easily install or remove the cleaning roller 300 using only the roller handle 330, avoiding the inconvenience of contact with wastewater on the cleaning roller 300.

[0079] Furthermore, to improve the sealing of the airflow path of the cleaning robot 1, thereby enhancing its ability to adsorb dirt from the ground, the aforementioned storage box 200 also includes a sealing ring 250. In addition, the cleaning robot 1 also includes several sealing rubber rings 350. For details, please refer to [link / reference needed]. Figure 7 The sealing ring 250 is located on the periphery of the receiving groove 204 and is in a closed shape. The first groove 101 has a mounting surface corresponding to the sealing ring 250. When the storage box 200 is received in the first groove 101, the sealing ring 250 abuts against the mounting surface of the first groove 101, thereby achieving a sealed connection between the periphery of the receiving groove 204 of the storage box 200 and the mounting point of the first groove 101. This prevents external air from entering the receiving groove 204 from the gap at the contact point between the storage box 200 and the mounting surface of the first groove 101. In other words, it prevents the airflow provided by the fan assembly 700 from being dispersed to adsorb objects in the first groove 101, thereby improving the adsorption effect of the cleaning robot 1 on ground dirt.

[0080] Specifically, the sealing ring 250 has a first side rubber segment, a second side rubber segment, and two arc-shaped rubber segments connecting the two ends of the first side rubber segment and the second side rubber segment respectively around the periphery of the receiving groove 204. Correspondingly, the mounting surface of the first groove 101 has a first side bearing surface, a second side bearing surface, and two arc-shaped bearing surfaces connecting the two ends of the first side bearing surface and the second side bearing surface. The first side rubber segment bears and abuts against the first side bearing surface, the second side rubber segment bears and abuts against the second side bearing surface, and the two arc-shaped rubber segments bear and abut against the two arc-shaped bearing surfaces respectively, thereby ensuring the airtightness around the receiving groove 204 and thus improving the suction force of the suction channel on the receiving groove 204.

[0081] The aforementioned sealing rings 350 include a first sealing ring 351 and a second sealing ring 352.

[0082] In order to install the roller handle 330 in the first groove 101, the side wall of the first groove 101 is provided with a slot, the slot penetrates the mounting surface, that is, the slot penetrates a part of the arc-shaped bearing surface. In order to avoid the slot from compromising the airtightness, one end of the roller handle 330 is provided with a first sealing ring 351, which is inserted into the slot, so that one end of the cleaning roller can be rotatably supported on the side wall of the first groove 101. The first sealing ring 351 seals the mounting connection between the end and the slot, thereby ensuring airtightness by sealing the slot part connected to the arc-shaped bearing surface.

[0083] Furthermore, the first sealing ring 351 has a splicing surface, which is arc-shaped. The splicing surface and the arc-shaped bearing surface are spliced ​​together to form a complete arc. An arc-shaped rubber segment of the sealing ring 250 is adapted to and abuts against the splicing surface, which further improves the airtightness.

[0084] The other end of the aforementioned roller handle 330 forms a handle portion; please refer to the details. Figure 11 The handle allows users to easily lift the end of the cleaning roller and remove it.

[0085] Furthermore, the roller handle 330 is V-shaped overall, with the first sealing ring 351 nested and covering its small end, and the handle portion located at its large end. The slot is provided corresponding to the roller handle 330.

[0086] Please refer to the following for details. Figure 13In conjunction with other accompanying drawings, the second sealing ring 352 is installed on the base 410 of the roller power assembly 400. Specifically, the base 410 includes an output ring wall 411 surrounding the output terminal 430. The second sealing ring 352 is fitted onto the output ring wall 411. The output terminal 430 penetrates the groove wall of the first groove 101 and extends into the first groove 101, connecting to the other end of the cleaning roller. The second sealing ring 352 is used to seal the connection between the output terminal 430 and the robot body, preventing moisture from entering the robot body through the groove wall penetration of the output terminal 430. Furthermore, the output terminal 430 is located below an arc-shaped bearing surface to avoid affecting the airtightness around the receiving groove 204.

[0087] Of course, in other embodiments of the present invention, the second sealing ring 352 may also be disposed below the storage box 200 and at least partially abut against the wall of the receiving groove 204, which can also prevent external air from entering the receiving groove 204 from the end of the receiving groove 204.

[0088] For the aforementioned liquid storage tank 500, please refer to Figure 3 The storage tank 500 is used to contain cleaning fluid, which is applied to the cleaning roller 300 via a supply mechanism (not shown). Specifically, the storage chamber 500 has a storage cavity (not shown in the figure), and the storage box 200 has a first liquid channel and an outlet section that connects the first liquid channel to the external environment of the box body 210; wherein, the first liquid channel is isolated from the storage cavity 201. The supply mechanism includes an inlet end communicating with the storage cavity and an outlet end communicating with the first liquid channel. The cleaning fluid flowing out of the storage cavity passes sequentially through the inlet end of the supply mechanism, the outlet end of the supply mechanism, the first liquid channel, and the outlet section, and then flows to the cloth 320 of the cleaning roller 300, wetting the cloth 320.

[0089] Regarding the aforementioned first fluid channel, please refer to Figures 8 to 10The diagram shows cross-sectional views of the storage box 200 from two directions and a partially enlarged schematic diagram at point A. In conjunction with other accompanying drawings, a first liquid channel 205 is disposed in the receiving tank 204, along the forward direction of the cleaning robot 1. This first liquid channel 205 is located in front of the axis of the cleaning roller 300, while the aforementioned first external port 2022 is located behind the axis of the cleaning roller 300. In this embodiment, the first liquid channel 205 is formed by an enclosing member 260 and the tank wall of the receiving tank 204. Specifically, the wall of the receiving groove 204 is recessed to form a strip-shaped groove structure extending axially along the cleaning roller 300; the enclosing member 260 includes opposing side portions 261 and a bottom 262 connecting the side portions 261. Both the side portions 261 and the bottom 262 are arranged axially along the cleaning roller 300. The end of the side portion 261 away from the bottom 262 extends into the strip-shaped groove structure and is fixed to the wall of the receiving groove 204, so that the enclosing member 260 and the wall of the receiving groove 204 together form the first liquid channel 205. Optionally, the wall of the receiving groove 204 is provided with two opposing guide grooves 2041 within the strip-shaped groove structure. The guide grooves 2041 extend axially along the cleaning roller 300; correspondingly, the end of the side portion 261 away from the bottom 262 has a guide bar 2611 adapted to the guide groove 2041, and each guide bar 2611 is inserted into a guide groove 2041. A liquid outlet 206 is disposed on the enclosure 260, which is connected to the first liquid channel 205 and the receiving tank 204 respectively, so that the cleaning liquid in the first liquid channel 205 can enter the receiving tank 204 to wet the cleaning roller 300. In this embodiment, the liquid outlet 206 is disposed on one of the two sides 261 away from the suction channel 202, that is, the liquid outlet 206 is disposed on the side of the first liquid channel 205 away from the first outer port 2022. Correspondingly, the side 261 away from the suction channel 202 is recessed inward towards the other side 261, so that there is a gap between the side 261 away from the suction channel 202 and the side wall of the receiving tank 204 for the cleaning liquid to pass through. It is worth mentioning that the purpose of disposing of the liquid outlet 206 on the side away from the suction channel 202 is to minimize the probability of the liquid outlet 206 being blocked by dirt on the cleaning roller 300. It is understood that in other embodiments of the present invention, the liquid outlet 206 may also be disposed on the side 261 near the suction channel 202, or on the bottom 262. Optionally, the liquid outlet 206 includes a plurality of liquid outlet holes, which are spaced apart along the direction of extension of the cleaning roller 300; it is understood that in other embodiments of the present invention, the liquid outlet 206 may also be a narrow channel or other structure. In addition, the first liquid channel 205 may also be a hollow channel formed inside the bottom wall 2111 of the housing, or a pipe fixed to the wall of the receiving groove 204, as long as it is isolated from the receiving cavity 201.

[0090] Optionally, to accommodate the layout of the components within the housing 110, the receiving groove 204 has a first side 2042 and a second side 2043 extending axially along the cleaning roller 300 and at different heights. The first side 2042 and the second side 2043 are arranged opposite each other along the traveling direction of the cleaning robot 1, with the first side 2042 extending outward relative to the second side 2043. Along the traveling direction of the cleaning robot 1, the first side 2042 is located behind the second side 2043. The aforementioned first external port 2022 is located between the first side 2042 and directly above the axis of the cleaning roller 300, that is, between the first side 2042 and the top of the receiving groove 204. Since the first side 2042 is closer to the ground, and the first external port 2022 is close to the first side 2042, it is easier for dirt to climb up the groove wall of the receiving groove 204 from this side and enter the suction channel 202. The first liquid channel 205 is located between the second side 2043 and the top of the receiving tank 204. That is, the first external port 2022 is located between the first side 2042 and the first liquid channel 205.

[0091] Furthermore, to ensure that as much contaminant as possible is drawn into the collection cavity 201 from the circumferential surface of the cleaning roller 300, and to further reduce the probability of blockage of the liquid outlet 206, the collection box 200 also includes a scraping section. For details, please refer to [link to relevant documentation]. Figure 10 In conjunction with other accompanying drawings, the scraping part 270 is fixed to the wall of the receiving tank 204, located near the first outer port 2022 and between the first outer port 2022 and the first liquid channel 205. The scraping part 270 has a protruding structure, which is used to at least partially embed itself into the cleaning roller 300 when the receiving tank 204 contains at least a portion of the cleaning roller 300, so as to scrape off the dirt on the cleaning roller 300, and allow the dirt to be sucked into the receiving cavity 201 through the suction channel 202 under the adsorption of the fan assembly 700; at the same time, the scraping part 270 also serves to separate the first outer port 2022 and the first liquid channel 205, so as to prevent the dirt that is about to enter the suction channel 202 from passing over the scraping part 270 and covering and blocking the liquid outlet 206.

[0092] Further, please refer to Figure 6In conjunction with other accompanying drawings, the storage box 200 also includes a second liquid channel 207 located within and isolated from the storage cavity 201. This second liquid channel 207 has an inlet 2071 and an outlet 2072. The inlet 2071 is located on the box body 210 and communicates with the aforementioned liquid supply mechanism, while the outlet 2072 communicates with the first liquid channel 205. The cleaning fluid supplied from the outlet end of the liquid supply mechanism will flow sequentially through the second liquid channel 207, the first liquid channel 205, and the outlet section 206 to the cleaning roller 300. Preferably, from the inlet 2071 to the outlet 2072, the second liquid channel 207 gradually moves away from the top wall of the box body 210. Thus, a height difference is formed between the liquid inlet 2071 and the first liquid channel 205. This arrangement can, on the one hand, increase the flow rate of the cleaning liquid into the first liquid channel 205, thereby increasing the distance the cleaning liquid travels along the first liquid channel 205, so that the cleaning roller 300 is more evenly wetted; on the other hand, this arrangement can also prevent water from accumulating inside the second liquid channel 207.

[0093] Furthermore, in some embodiments, in order to facilitate the floor cleaning robot 1 to obtain the liquid level in the storage box 200 in a timely manner, and thus guide the user to clean up the dirt in a timely manner when the liquid level is high, the storage box 200 also includes a buoy and a first magnet installed on the buoy; correspondingly, the housing 110 is provided with a Hall element module and a controller, the Hall element module includes a first Hall element used in conjunction with the first magnet, and the controller is electrically connected to the first Hall element.

[0094] Specifically, please refer to Figure 9 and Figure 6In conjunction with other accompanying drawings, the housing 210 also includes a guide groove 208. This guide groove 208 extends from the bottom of the receiving cavity 201 to the top of the receiving cavity 201 and communicates with the receiving cavity 201, allowing the liquid level in the guide groove 208 to rise and fall together with the liquid level in the receiving cavity 201. In this embodiment, the housing 210 forms an enclosing wall 2116 within the receiving cavity 201. This enclosing wall 2116 starts from the bottom wall 211 of the housing and extends towards the top wall. The enclosing wall 2116, together with the bottom wall 2111 and side wall 2112 of the housing, forms the guide groove 208. Furthermore, the enclosing wall 2116 has a notch extending from the bottom to the top of the receiving cavity 201, which connects the guide groove 208 and the receiving cavity 201, allowing the guide groove 208 to communicate with the receiving cavity 201. The buoy 280 is housed within the guide channel 208 and rises and falls with the liquid level in the guide channel 208 and the receiving cavity 201, thereby causing the first magnet 281 mounted thereon to rise and fall together. Optionally, the buoy 280 is foam; it is understood that in other embodiments of the present invention, the buoy 280 may also be other plastics besides foam, or other materials with a density lower than that of sewage and that do not chemically react with sewage. Further optionally, the housing 210 is also provided with a limiting structure (not shown in the figure), which is housed in the receiving cavity 201 and located at the top of the guide channel 208, and is used to prevent the buoy 280 from leaving the guide channel 208 from the top of the guide channel 208; in this embodiment, the limiting structure at least partially extends into the guide channel 208. The first Hall element (not shown in the figure) is installed on the housing 110 and positioned near the top of the guide groove 208. It works in conjunction with the first magnet 281 to detect whether the float 280 has floated to a preset position. The preset position is a position near the top of the storage cavity 201. When the float 280 floats to the preset position, the first Hall element detects that it has reached the position and then sends a signal to the controller. The controller performs relevant operations based on the signal to guide the user to clean up the dirt in a timely manner.

[0095] Furthermore, please refer back to [link / reference]. Figure 3In conjunction with other accompanying drawings, the robot body 100 also includes an output module 140. The floor cleaning robot 1 uses this output module 140 to interact with the user, guiding the user to promptly clean up dirt when the liquid level in the receiving cavity 201 reaches a preset value. Specifically, the output module 140 is installed on the top of the housing 110 and electrically connected to the controller. It is used to output warning signals. When the float 280 floats to a preset position, the first Hall element detects that the float 280 is in position and sends a signal to the controller. The controller then controls the output module 140 to output a warning signal based on this signal. Optionally, the output module 140 includes a display panel for displaying visual warning signals such as images and text, thereby prompting the user to clean the storage box 200 of dirt. In addition, in some other embodiments, the output module 140 may also include an audio output device, which is a device capable of outputting sound, such as a speaker or buzzer. The audio output device is used to output a set audio audible warning signal, thereby prompting the user to clean the storage box 200 of dirt. Of course, in other embodiments, the output module 140 may also include both a display panel and an audio output device.

[0096] Furthermore, in some embodiments, to enable the controller to promptly determine whether the storage box 200 is accommodated within the first groove 101 and properly installed, thereby facilitating subsequent cleaning operations, the storage box 200 also includes a second magnet (not shown in the figure); correspondingly, the aforementioned Hall element module also includes a second Hall element (not shown in the figure) used in conjunction with the second magnet, and the second Hall element is electrically connected to the aforementioned controller. Specifically, the second magnet is installed in the box 210. In this embodiment, the second magnet is disposed within the wall of the box 210 and near the bottom of the box 210 by means of insert molding; it is understood that in other embodiments of the present invention, the second magnet can also be fixed to the box 210 by other means such as bonding, screwing, or snap-fitting, which will not be detailed here. The second Hall element (not shown in the figure) is installed in the housing 110 and located near the bottom of the box 210. It is used to cooperate with the 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 it is in place and then sends a signal to the controller. The controller controls the floor cleaning robot to switch to a mode state in which cleaning operations can be performed according to the signal. Otherwise, it switches to a mode state in which cleaning operations cannot be performed.

[0097] Furthermore, in some embodiments, the storage box 200 also includes a handle to facilitate user retrieval. For details, please refer to the relevant documentation. Figure 3 and Figure 6In conjunction with other accompanying drawings, the handle 290 is generally arc-shaped, with its two ends rotatably mounted on the top or top wall of the side wall 2112 of the box body 210. It can be rotated to be perpendicular or parallel to the top wall of the box body 210. The user can take out the storage box 200 by lifting the middle area of ​​the handle 290. Preferably, the outer surface of the top wall of the box body 210 is provided with a handle storage groove (not shown in the figure) that is adapted to the handle 290. When the storage box 200 is received in the first groove 101, the handle 290 can be rotated into the handle storage groove to avoid the handle 290 protruding from the surface of the box body 210 and affecting the effect of the first flap 120 covering the opening of the first groove 101.

[0098] Furthermore, the present invention further improves the structure of the handle 290 to enhance the fixation effect of the storage box 200 relative to the robot body 100 in the height direction when it is housed in the first groove 101. For details, please refer to... Figure 14 It shows Figure 6The enlarged view at point B, along with other accompanying drawings, shows that the end of the handle 290 has a limiting groove 291 on its end face away from its center. The limiting groove 291 extends along a predetermined direction, with its first end 2911 closed and its second end 2912 extending through the end of the handle 290 from the first end 2911 along the aforementioned predetermined direction. Correspondingly, the robot body 100 has a limiting post (not shown in the figure) facing the limiting groove 291. This limiting post works in conjunction with the limiting groove 291 to constrain the degree of freedom of movement of the storage box 200 along the height direction of the cleaning robot 1. Specifically, during the process of the storage box 200 being received into the first groove 101 and the handle 290 rotating from the first preset position to the second preset position, the aforementioned limiting post slides from the second end 2912 of the limiting groove 291 to the first end 2911 relative to the handle 290, thus restricting the degree of freedom of movement of the storage box 200 along the height direction of the cleaning robot 1; during the process of the handle 290 rotating from the second preset position to the first preset position, the limiting post disengages from the second end 2912 from the limiting groove 271, allowing the user to freely lift the storage box 200. The first preset position is a position where the handle 290 is perpendicular to the top wall of the box body 210, and the second preset position is a position where the handle 290 is parallel to the top wall of the box body 210. At this time, the handle 290 is received in the aforementioned handle storage groove. In this embodiment, the axis of the first end 2911 is collinear with the rotation axis of the handle 290, and the second end 2912 extends along a preset direction and passes through the end of the handle. In other embodiments of the present invention, the axis of the first end 2911 may also be offset from the rotation axis of the handle 290. Correspondingly, the second end 2912 extends along the aforementioned preset direction and passes through the end. In this case, the aforementioned preset direction is the rotation direction of the handle 290 from the first preset position to the second preset position. It is worth mentioning that the setting of the limiting groove 291 and the limiting post can also remind the user that the storage box 200 can only be lifted out when the handle is rotated to the vertical position, so as to ensure the overall balance of the storage box 200 during the process of detaching from the first groove 101.

[0099] Furthermore, considering that when the cleaning robot 1 lands, the cleaning roller 300 is in contact with the ground, while the robot body 100 is above the ground, and that there is no obstruction behind the cleaning roller 300 during the movement of the cleaning robot 1, the air behind the cleaning roller 300 will enter the aforementioned suction channel 202 through the gap between the cleaning roller 300 and the robot body 100. This will reduce the adsorption effect of the fan assembly 700 on ground dirt. To overcome this deficiency, the cleaning robot 1 also includes a scraper 800. For details, please refer to... Figure 15 It shows Figure 4The enlarged view at point C, along with other accompanying drawings, shows that the scraper 800 extends parallel to the axial direction of the cleaning roller 300. It is mounted on the bottom of the robot body 100 and positioned close to the cleaning roller 300. When the cleaning robot 1 lands, the scraper 800 makes interference contact with the ground. Along the forward direction of the cleaning robot 1, the scraper 800 is located behind the cleaning roller 300. The scraper 800 serves two purposes: firstly, it acts as a barrier behind the cleaning roller 300, forming a nearly enclosed negative pressure space together with the cleaning roller 300 and the robot body 100. This prevents outside air from entering the space, thereby enhancing the negative pressure adsorption effect of the cleaning robot on ground dirt and dirt on the cleaning roller 300. The scraper 800 also serves to collect dirt that was not promptly removed during the initial rotation of the cleaning roller 300 and dirt that was not promptly absorbed into the collection cavity 201 by the fan assembly 700. This allows the cleaning roller 300 to continuously rotate and the fan assembly 700 to continuously absorb the dirt collected by the scraper 800 into the collection cavity 201. Optionally, the scraper 800 includes a fixing part 810 and a connecting part 820; wherein the fixing part 810 is installed on the bottom of the robot body 100, one end of the connecting part 820 is fixed to the fixing part 810, and the other end extends in a direction away from the robot body 100. Preferably, when the cleaning robot 1 lands, the connecting part 820 makes interference contact with the ground. Preferably, the fixing part 820 is at least partially attached to the outer end of the cloth 320 of the cleaning roller 300, that is, at least part of the scraper 800 is attached to the circumferential surface of the cleaning roller 300. In this way, on the one hand, the gap between the scraper 800 and the cleaning roller 300 is reduced, that is, the volume of the negative pressure space is reduced, which helps to improve the negative pressure adsorption effect of the blower assembly 700. On the other hand, it also helps to appropriately increase the friction between the cleaning roller 300 and the scraper 800 for larger waste, which makes it easier for larger waste to climb.

[0100] The cleaning robot 1 provided in this embodiment of the invention includes a robot 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 drive wheel assembly 600. The storage box 200 includes a box body 210, a cover assembly 220, a cover drive assembly 230, and a locking assembly 240.

[0101] The housing 210 includes a box 211, a lid 212, and a sealing ring 213. The lid 212 covers the box 211 and forms a storage cavity 201. The sealing ring 213 is located at the connection between the lid 212 and the box 211 and seals the connection. Therefore, even if the cleaning robot 1 tilts or is inverted, the liquid in the storage cavity 201 will be prevented from leaking out due to the sealing ring 213. Thus, the storage box 200 effectively prevents the liquid in the storage cavity 201 from leaking out; similarly, the cleaning robot 1, including the storage box 200, can also effectively prevent the liquid in the storage cavity 201 from leaking out.

[0102] The housing 210 is provided with an air intake channel 202 that connects the storage cavity 201 and the external environment of the housing 210, and an air outlet channel 203 that connects the storage cavity 201 and the external environment of the housing 210. The cover assembly 220 includes a cover 221, which is housed in the storage cavity 201 and can move between a sealed position and an unsealed position. In the sealed position, the cover seals the air intake channel and the air outlet channel; in the unsealed position, the cover unseales the air intake channel and the air outlet channel. Therefore, after the cleaning robot 1 provided by the present invention stops working, the storage box 200 can cover and seal the air intake channel 202 and the air outlet channel 203 by placing the cover 221 in the sealed position, thereby preventing sewage from overflowing from the air intake channel and the air outlet channel. This avoids the disadvantage that sewage may overflow from the air intake channel 202 and / or the air outlet channel 203 when the user picks up the cleaning robot 1 due to the slight tilt of the cleaning robot 1.

[0103] The cleaning robot 1 utilizes the characteristic that its wheel arm 610 rotates relative to the robot body 100 when it leaves or lands. A protrusion 613 on the wheel arm 610 drives a push rod 231 in the cover drive assembly 230 to move between a first position and a second position, thereby driving the cover 221 to move between a sealed position and an unsealed position, thus opening and closing the first inner port 2021 and the second inner port 2031. When the cleaning robot lands, the protrusion moves with the wheel arm to the mating position, and the cover 221 is in the unsealed position, allowing the cleaning robot to perform normal floor cleaning operations. When the cleaning robot leaves the ground, the protrusion 613 moves with the wheel arm 610 to the separation position, and the cover 221 is in the sealed position, preventing wastewater from overflowing from the suction channel 202 and the exhaust channel 203. Therefore, the cleaning robot 1 provided by this invention makes the process of switching the cover 221 between the sealed and unsealed positions extremely convenient.

[0104] The bottom wall of the housing 210 is at least partially recessed to form a receiving groove 204. The first outer port 2022 of the suction channel 202 is located on the groove wall of the receiving groove 204 and communicates with the receiving groove 204. The first inner port 2021 of the suction channel 202 communicates with the storage cavity 201. The second inner port 2031 of the exhaust channel 203 communicates with the storage cavity 201, and the second outer port 2032 of the exhaust channel 203 communicates with the external environment. A sealing ring 250 is located around the periphery of the receiving groove 204 and is in a closed shape. Therefore, when the receiving box 200 is installed 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 receiving box 200 and the mounting surface of the first groove 101, thereby reducing the amount of air from the external environment entering the receiving groove 204. This improves the efficiency of the fan assembly in removing dirt; that is, it improves the dirt-removing efficiency of the cleaning robot 1.

[0105] The storage box 200 is further provided with a first liquid channel 205 and a liquid outlet 206 that connects the first liquid channel 205 to the external environment. The first liquid channel 205 is isolated from the storage cavity 201 and is used to communicate with the liquid supply mechanism. Thus, the storage box 200 integrates a first liquid channel 205 that can communicate with the liquid supply mechanism and output liquid to the outside through the liquid outlet 206; that is, the storage box 200 integrates the function of receiving and spraying cleaning liquid. Therefore, the cleaning robot 1 provided by the present invention does not need to be equipped with a separate spray pipe, which is conducive to the miniaturization of the cleaning robot.

[0106] Furthermore, the cleaning robot 1 provided in this embodiment of the invention also includes a scraper 800. The scraper 800 is installed at the bottom of the robot body 100 and is positioned near the cleaning roller 300. When the cleaning robot 1 lands, the scraper 800 makes interference contact with the ground. Thus, the scraper 800, the cleaning roller 300, and the robot body 100 form a nearly sealed negative pressure space. As the cleaning robot 1 moves towards the side of the cleaning roller 300 away from the scraper 800, the scraper 800 acts as a barrier behind the cleaning roller 300, preventing outside air from entering the aforementioned space, thereby enhancing the negative pressure adsorption effect of the cleaning robot 1 on ground dirt.

[0107] Based on the same inventive concept, the present invention also provides a storage box, which has the same structure as the storage box 200 in the above embodiments. The specific structure and beneficial effects of this storage box are the same as those of the storage box 200 in the above embodiments, and will not be described again here.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
