[0022] The present invention provides an embodiment of a cleaning robot, see Figure 1 and Figure 2The cleaning robot 1 includes a housing 2, a storage box 3 and a liquid storage tank 4. The housing 2 is provided with a first groove 20 and a second groove 22. The storage box 3 is located in the first groove 20 and is used to store dirt, including but not limited to sewage, debris, dust, dirt and hair. The liquid storage tank 4 is located in the second groove 22 and is used to store cleaning liquid, including but not limited to clean water, detergent, cleaning liquid and a combination thereof.

[0023] The cleaning robot 1 of this embodiment is provided with a first groove 20 and a second groove 22 spaced apart on the shell 2. The first groove 20 accommodates the storage box 3, and the second groove 22 accommodates the liquid storage tank 4. The storage box 3 and the liquid storage tank 4 are spaced apart and arranged separately, thereby increasing the volume of the liquid storage tank 4 and improving the cleaning area of ​​the cleaning robot 1 for storing liquid at one time. At the same time, compared with the water tank integrating the sewage chamber and the clean water chamber, the structure of the liquid storage tank 4 is simplified.

[0024] In this embodiment, the storage box 3 and the liquid storage tank 4 are both located in the forward direction of the cleaning robot 1, and the storage box 3 is located in the front and the liquid storage tank 4 is located in the rear. However, in other embodiments, the storage box 3 can be located in the rear and the liquid storage tank 4 can be located in the front; in addition, the storage box 3 and the liquid storage tank 4 can also be located separately in the same groove.

[0025] In this embodiment, the cleaning robot 1 further includes a cleaning roller 5 and a liquid supply mechanism (not shown). The cleaning roller 5 is arranged in the housing 2 and is located below the storage box 3. The first groove 20 corresponding to the cleaning roller 5 and the bottom of the housing 2 corresponding to the cleaning roller 5 are both arranged to avoid interference with the cleaning of the ground by the cleaning roller 5. The liquid supply mechanism is arranged in the housing 2 and has a liquid inlet end (not shown) and a liquid outlet end (not shown). The liquid inlet end is used to connect to the liquid storage tank 4, and the liquid outlet end outputs cleaning liquid to the cleaning roller 5 through the storage box 3.

[0026] Since the cleaning roller 5 is arranged below the storage box 3, and the liquid supply mechanism supplies the cleaning liquid in the liquid storage tank 4 to the cleaning roller 5 through the storage box 3, that is, the cleaning liquid is directly sprayed and dripped from the storage box 3 onto the cleaning roller 5 below it, and the cleaning roller 5 is fully wetted, thereby improving the cleaning effect of the cleaning robot 1 and avoiding the situation that the water amount on the ground is uneven and the ground is not wetted locally when the cleaning liquid is directly sprayed on the ground. However, in other embodiments, a liquid channel can be arranged in the roller shaft of the cleaning roller 5, and the liquid supply mechanism inputs the cleaning liquid into the liquid channel to directly wet the cleaning roller 5.

[0027] In this embodiment, the housing 2 includes a chassis 24 and a surface shell 26, a first groove 20 and a second groove 22 are provided on the surface shell 26, and the liquid supply mechanism is located between the chassis 24 and the surface shell 26, and is fixed on the surface shell 26. A connecting portion 60 is provided at the bottom of the second groove 22 of the surface shell 26, one end of the connecting portion 60 is inserted into the liquid storage tank 4, and the other end is connected to the liquid inlet end of the liquid supply mechanism, thereby connecting the liquid storage tank 4 and the liquid supply mechanism, and the liquid supply mechanism is preferably a water pump mechanism. The roller drive assembly of the cleaning robot 1 is installed between the chassis 24 and the surface shell 26, and the chassis 24 is arranged to avoid the part of the cleaning roller 5 corresponding to the air, and the two ends of the cleaning roller 5 are installed in the housing 2, and one end thereof is connected to the roller drive assembly (not shown), and the roller drive assembly drives the cleaning roller 5 to rotate.

[0028] In this embodiment, the cleaning robot 1 further includes a fan (not shown) and a battery (not shown) disposed between the surface shell 26 and the chassis 24 . The fan and the battery are located in the interval between the first groove 20 and the second groove 22 .

[0029] See also Figure 4 and Figure 5 In this embodiment, the storage box 3 includes a box body 30 and a first liquid channel 34. The box body 30 is provided with a suction port 300 for sucking in dirt and an air extraction port 302 for exhausting gas. The air extraction port 302 is connected to the fan, and a receiving groove 32 for receiving at least part of the cleaning roller 5 is provided at the bottom of the box body 30. The receiving groove 32 is connected to the suction port 300. The first liquid channel 34 is located in the receiving groove 32, is arranged along the axial direction of the cleaning roller 5, and has a liquid outlet for outputting the cleaning liquid. The liquid outlet is preferably a plurality of liquid outlet holes 340. However, in other embodiments, the liquid outlet can be a narrow liquid outlet gap or other structures.

[0030] The storage box 3 is provided with a receiving groove 32 for receiving the cleaning roller 5 at the bottom of the box body 30, and the first liquid channel 34 is located in the receiving groove 32, and then the first liquid channel 34 directly outputs the cleaning liquid to the cleaning roller 5, so that the cleaning roller 5 is fully moistened, and the cleaning effect is further improved. In addition, the suction port 300 of the box body 30 is connected with the receiving groove 32. When the cleaning roller 5 of the cleaning robot 1 is working, the cleaning roller 5 rotates in the receiving groove 32, which can accelerate the moistening of the cleaning roller 5 and at the same time can lift up sewage, debris, etc. At this time, the fan exhausts air, and the gas in the storage box 3 is discharged through the exhaust port 302, thereby forming a negative pressure in the suction port 300. The suction port 300 can easily suck the sewage and debris into the storage box 3 without increasing the suction force of the cleaning robot 1.

[0031] In this embodiment, preferably, the plurality of liquid outlet holes 340 are spaced apart and distributed along the axial direction of the cleaning roller 5 , so that the cleaning liquid can be evenly distributed on the entire cleaning roller 5 , and the cleaning roller 5 can be quickly wetted.

[0032] See also Figure 3 and Figure 4 In this embodiment, the first liquid channel 34 includes an enclosure 342, and the enclosure 342 and the groove wall of the receiving groove 32 are enclosed to form the first liquid channel 34. Specifically, the enclosure 342 is fixed to the groove wall of the receiving groove 32 by gluing, and has good sealing performance and is convenient for assembly. However, in other embodiments, the first liquid channel 34 can be formed in the groove wall of the receiving groove 32, that is, a hollow channel is formed in the groove wall, and a plurality of liquid outlet holes 340 are provided on the groove wall; the first liquid channel 34 can also be a pipe directly fixed on the groove wall of the receiving groove 32, and a plurality of liquid outlet holes 340 are provided on the pipe.

[0033] See also Figure 2 and Figure 3 In this embodiment, the enclosure 342 has two opposite side portions 344, which are arranged along the axial direction of the cleaning roller 5. Two opposite guide grooves 346 are formed on the groove wall of the receiving groove 32, and each side portion 344 is located in a guide groove 346. Through the cooperation between the side portions 344 and the guide grooves 346, positioning and assembly are easy, and the glue bonding and sealing effects are better.

[0034] See also Figure 3 In this embodiment, the enclosure 342 has a bottom surface 348 and a side surface, the bottom surface 348 faces the cleaning roller 5, the side surface is connected to the bottom surface 348 and is arranged along the axial direction of the cleaning roller 5, and a plurality of liquid outlet holes 340 are opened on the bottom surface 348. The side surface is the outer surface of the side portion 344. However, in other embodiments, the enclosure 342 protrudes from the groove wall of the receiving groove 32, that is, the side surface of the enclosure 342 is not embedded in the guide groove 346 of the groove wall, and a plurality of liquid outlet holes 340 can be opened on the side surface. Since the plurality of liquid outlet holes 340 are opened on the side surface of the enclosure 342, the dirt rolled up by the cleaning roller 5 is not easy to contact the liquid outlet holes 340, thereby preventing the liquid outlet holes 340 from being blocked. It can be understood that the enclosure 342 can be in the shape of a square bar or a round bar. When the enclosure 342 is in the shape of a round bar, the side surface can be understood as the surface of the enclosure 342 other than the part closest to the cleaning roller 5.

[0035] See also Figure 5 In this embodiment, the storage box 3 also includes a second liquid channel 35, which is arranged in the box body 30 and has a liquid inlet 350 and a liquid outlet 352. The liquid inlet 350 is opened on the box body 30, and the liquid outlet 352 is connected to the first liquid channel 34.

[0036] The liquid outlet of the liquid supply mechanism inputs the cleaning liquid from the liquid inlet 350 of the second liquid channel 35, and the cleaning liquid flows through the second liquid channel 35 and is output from the liquid outlet 352 and enters the first liquid channel 34. Since the second liquid channel 35 is arranged in the box body 30, it is isolated from the storage space in the box body 30, and the sewage in the box body 30 will not affect the cleaning liquid in the second liquid channel 35. However, in other embodiments, the second liquid channel 35 can be arranged outside the box body 30 and can be connected to the first liquid channel 34 through the side wall of the box body 30.

[0037] In this embodiment, the second liquid channel 35 may be, but is not limited to, a soft rubber tube or a plastic part with a hollow channel.

[0038] In this embodiment, the receiving groove 32 is arc-shaped, and has a first side 320 and a second side 322 in the axial direction of the cleaning roller 5. The suction port 300 is provided on the groove wall of the receiving groove 32 between the first side 320 and the first liquid channel 34, and the first side 320 is extended relative to the second side 322. Since the first side 320 is extended relative to the second side 322, that is, the first side 320 of the receiving groove 32 is closer to the ground, and the suction port 300 is close to the first side 320, so that the sewage can more easily pass through the first side 320 and enter the suction port 300 along the groove wall.

[0039] In this embodiment, the first liquid channel 34 is located at the top of the receiving groove 32 , which is located directly above the cleaning roller 5 , and the cleaning liquid can be completely sprayed or dripped on the cleaning roller 5 .

[0040] See also Figure 4 and Figure 5 In this embodiment, the storage box 3 further includes a bracket 36, a push rod assembly 37 and a sealing structure 38. The bracket 36 has a first end 360 and a second end 362. The first end 360 is hinged to the inside of the box body 30, and the second end 362 is used to open or seal the suction port 300 and the air extraction port 302. The sealing structure 38 is used to keep the second end 362 sealed at the suction port 300 and the air extraction port 302. The push rod assembly 37 is arranged in the box body 30 and can be retracted outside the box body 30, and has a first position and a second position:

[0041] When located at the first position, the push rod assembly 37 abuts against the bracket 36, and the second end 362 opens the suction port 300 and the air extraction port 302;

[0042] When located at the second position, the push rod assembly 37 is away from the bracket 36 , and the second end 362 seals the suction port 300 and the air extraction port 302 .

[0043] By arranging the bracket 36 and the push rod assembly 37 in the storage box 3, wherein the bracket 36 can be rotatably connected to the inside of the box body 30, and the push rod assembly 37 can be movably arranged relative to the box body 30. When the push rod assembly 37 is located at the first position, the push rod assembly 37 abuts against the bracket 36, and the second end 362 of the bracket 36 opens the suction port 300 and the air extraction port 302, and the air is sucked away by the fan through the air extraction port 302, and a negative pressure is formed at the suction port 300, and the sewage is sucked into the box body 30 under the action of the negative pressure; when the push rod assembly 37 is located at the second position, the push rod assembly 37 is away from the bracket 36, and the second end 362 of the bracket 36 seals the suction port 300 and the air extraction port 302 under the action of the sealing structure 38, which can ensure the sealing performance, prevent sewage leakage, and improve the sealing performance of the storage box 3.

[0044] In this embodiment, the box body 30 includes a box 304 and a box cover 306 disposed on the box 304, and a bracket 36 and a push rod assembly 37 are disposed in the box 304. The suction port 300 and the air extraction port 302 are opened on the box 304. A boss 308 is disposed in the box 304, and the push rod assembly 37 is disposed on the boss 308 and is located under the bracket 36. Since the push rod assembly 37 is located on the boss 308, the position of the push rod assembly 37 is raised to prevent sewage from overflowing from the push rod assembly 37. At the same time, since the push rod assembly 37 is located below the bracket 36, the push rod assembly 37 can lift or lower the bracket 36 through lifting and lowering activities, so that the suction port 300 and the air extraction port 302 can be easily opened or sealed.

[0045] In this embodiment, the top rod assembly 37 includes a top shaft 370 and a seal 372. The seal 372 is located in the box 304. The top shaft 370 passes through the boss 308 and the seal 372 and moves up and down. The top shaft 370 can move up and down to lift and lower the bracket 36. The seal 372 plays a sealing role to prevent sewage from overflowing from the connection of the top shaft 370. The seal 372 is preferably a sealing rubber pad.

[0046] In this embodiment, the first end 360 of the bracket 36 is disposed on the boss 308, and the push rod assembly 37 also located on the boss 308 can more conveniently lift or lower the bracket 36. However, in other embodiments, the first end 360 of the bracket 36 can be disposed on the side wall of the box 304 or on the inner surface of the box cover 306. Since the hinged connection of the first end 360 of the bracket 36 is a conventional structure, it will not be described in detail here.

[0047] In this embodiment, the sealing structure 38 is a push rod assembly, which is arranged on the box cover 306 and pushes against the bracket 36 in the direction of sealing the suction port 300 and the air outlet 302. Specifically, the push rod assembly has a retractable push rod, which always pushes down against the second end 362 of the bracket 36 to seal the suction port 300 and the air outlet 302.

[0048] The push rod assembly can always keep the bracket 36 sealing the suction port 300 and the air outlet 302 when the push rod assembly 37 does not abut the bracket 36 to prevent leakage; when the push rod assembly 37 abuts the bracket 36, the upward force applied by the push rod assembly 37 is greater than the downward force applied by the push rod assembly, thereby opening the suction port 300 and the air outlet 302. However, in other embodiments, the sealing structure 38 can be a magnetic adsorption structure, for example, a first magnetic adsorption member is provided on the suction port 300 and / or the air outlet 302, and a second magnetic adsorption member is provided on the bracket 36, and the first magnetic adsorption member and the second magnetic adsorption member are magnetically adsorbed; the sealing structure 38 can also be a torsion spring, which is provided at the hinge of the first end 360 of the bracket 36, and the elastic force of the torsion spring always forces the bracket 36 to rotate in the direction of sealing the suction port 300 and the air outlet 302.

[0049] In this embodiment, the suction port 300 and the air extraction port 302 are channel-shaped and have an outer end and an inner end, the inner end of the suction port 300 and the inner end of the air extraction port 302 are arranged flush, and the second end 362 of the bracket 36 is flat and matches the inner end of the suction port 300 and the inner end of the air extraction port 302. Since the second end 362 of the bracket 36 is flat, it is convenient for the bracket 36 to seal and open the suction port 300 and the air extraction port 302 at the same time, and the matching effect is good, and the sealing effect is good.

[0050] In this embodiment, a first sealing ring is provided between the second end 362 of the bracket 36 and the suction port 300, and a second sealing ring is provided between the second end 362 of the bracket 36 and the air suction port 302. The first sealing ring and the second sealing ring further improve the sealing effect.

[0051] See also Figure 2 and Figure 5 In this embodiment, the cleaning robot 1 further includes a driving wheel assembly 7, which is disposed in the housing 2 and mounted on the chassis 24. The driving wheel assembly 7 includes a wheel bracket 70 and a wheel arm 72, the wheel bracket 70 is fixed in the housing 2, and the wheel arm 72 is rotatably connected to the wheel bracket 70. The wheel arm 72 is provided with a protrusion 720 corresponding to the push rod assembly 37, and the wheel bracket 70 is provided with a clearance portion corresponding to the protrusion 720, so that the protrusion 720 can have a mating position and a separation position with the movement of the wheel arm 72:

[0052] When the protrusion 720 is located at the matching position, the protrusion 720 matches with the push rod assembly 37, the push rod assembly 37 moves to the first position, the push rod assembly 37 abuts against the bracket 36, and the second end 362 opens the suction port 300 and the air extraction port 302;

[0053] When the protrusion 720 is located at the separation position, the protrusion 720 is separated from the push rod assembly 37, the push rod assembly 37 moves to the second position, the push rod assembly 37 is away from the bracket 36, and the second end 362 seals the suction port 300 and the exhaust port 302.

[0054] The cleaning robot 1 of this embodiment utilizes the characteristic that the wheel arm 72 rotates relative to the wheel bracket 70 when it leaves the ground or lands, and a protrusion 720 is added to the wheel arm 72, and a clearance portion is provided on the wheel bracket 70 to prevent interference with the rotation of the protrusion 720. As the protrusion 720 rotates, it cooperates with the push rod assembly 37, thereby opening or sealing the suction port 300 and the air extraction port 302. When the cleaning robot 1 lands, under the action of the body's own weight, the wheel arm 72 rotates upward relative to the body and drives the protrusion 720 to move to the matching position, the protrusion 720 lifts the push rod assembly 37, and the push rod assembly 37 moves to the first position, thereby opening the suction port 300 and the air extraction port 302; when the cleaning robot 1 leaves the ground or takes out the storage box 3, the protrusion 720 of the wheel arm 72 separates from the push rod assembly 37, and under the action of the push rod assembly, the bracket 36 seals the suction port 300 and the air extraction port 302 to prevent sewage leakage.

[0055] In this embodiment, the cleaning robot 1 further includes a rotating member 8, which is rotatably mounted in the housing 2 and is located between the protruding portion 720 and the push rod assembly 37. When the protruding portion 720 is in the mating position, the protruding portion 720 is mated with the push rod assembly 37 through the rotating member 8; when the protruding portion 720 is in the separation position, the rotating member 8 is separated from the push rod assembly 37. The specific working mode of the rotating member 8 is as follows:

[0056] When the cleaning robot 1 lands, the wheel arm 72 rotates, and the linkage protrusion 720 moves to the matching position. At the same time, the protrusion 720 drives the rotating member 8 to rotate upward, and the rotating member 8 cooperates with the push rod assembly 37 to push the push rod assembly 37 to move to the first position.

[0057] When the cleaning robot 1 leaves the ground, the wheel arm 72 rotates, and the linkage protrusion 720 moves to the separation position, the protrusion 720 separates from the rotating member 8, the rotating member 8 separates from the push rod assembly 37, and the push rod assembly 37 moves to the second position; when the cleaning robot 1 takes out the storage box 3, the push rod assembly 37 separates from the rotating member 8, and under the action of the push rod assembly, the bracket 36 seals the suction port 300 and the exhaust port 302 to prevent sewage leakage.

[0058] The rotating member 8 of this embodiment is conducive to transmitting the rotation of the protrusion 720 to the top rod assembly 37, so that it works stably and has reliable performance. The rotating member 8 is preferably a rotating plate, which is hinged in the housing 2.

[0059] The present invention also provides another embodiment of the cleaning robot. Figure 4 and Figure 5 The cleaning robot 1 of this embodiment is different from the cleaning robot 1 of the above embodiment as follows:

[0060] The storage box 3 of the cleaning robot 1 of this embodiment also includes a driving mechanism (not shown), which is arranged outside the box body 30 and connected to the push rod assembly 37. The driving mechanism is used to drive the push rod assembly 37 to move to open or seal the suction port 300 and the exhaust port 302.

[0061] In this embodiment, the driving mechanism may be a cylinder driving mechanism, a motor driving mechanism or other driving mechanisms, which has a telescopic shaft that can move up and down, and the telescopic shaft is connected to the push rod assembly 37 to drive the push rod assembly 37 to move up and down.
