The installation positions of the left and right driving wheels 21 and the omnidirectional wheels 22 are distributed in a triangular shape to improve the walking stability of the cleaning robot during operation.

[0052] The main body 100 may be provided with a groove 110, the cleaning assembly 30 is installed in the groove 110, and the cleaning assembly 30 is connected to the first suction port 101 to clean dirt on the surface to be cleaned. The cleaning robot may also include a side brush 24, the side brush 24 is installed at the edge of the main body 100, and the side brush 24 extends out of the outer edge of the main body 100 to clean corners or low spaces that the cleaning robot cannot enter.

[0053] The storage device 40 is installed in the middle of the main body 100 and is connected to the first suction port 101 of the main body 100. The fan 50 is attached to the main body 100 to suck the dirt on the surface to be cleaned into the storage device 40 through the first suction port 101. It is conceivable that the cleaning robot may further include a controller 23 for controlling the cleaning robot to perform cleaning work and other components such as a power supply battery.

[0054] See also Figure 4 and Figure 4A , Figure 4 yes Figure 3 The cross-sectional view along the AA line. Figure 4A yes Figure 4 The main body 100 is also provided with a scraper 105 and a baffle 106, the first suction port 101 is sandwiched between the scraper 105 and the baffle 106, the scraper 105 extends from the main body toward the cleaning component 30, and at least partially contacts the surface of the cleaning component 30, so that during the operation of the cleaning robot, the scraper 105 scrapes the dirt attached to the cleaning component 30 to the surface to be cleaned, and the fan 50 sucks the dirt on the surface to be cleaned into the storage device 40 through the first suction port 101. The dirt may include debris or sewage, etc.

[0055] In this embodiment, the cleaning component 30 includes a first cleaning component 31, which is installed at the first suction port 101, and is configured to clean the sewage on the surface to be cleaned to the first suction port 101. The first cleaning component 31 is a rotary mopping component, which includes a first rotating shaft 310, a mopping connector 311 and a mopping component 312 arranged outside the first rotating shaft 310, and the mopping component 312 is covered on the outside of the mopping connector 311, and the mopping component 312 and the mopping connector 311 can be bonded by Velcro, or the mopping connector 311 is provided with a groove, and the mopping component 312 is stuck in the groove for fixed connection. The mopping component 312 can be a mop, a sponge or other components that can clean the sewage on the surface to be cleaned, and the mopping connector 311 can also be made of elastic material.

[0056] The first scraper 1051 is provided at the groove 110 where the first cleaning component 31 is installed. The first suction port 101 is sandwiched between the first scraper 1051 and the first baffle 1061. The first baffle 1061 is provided on the rear wall surface of the first suction port 101. The length of the first baffle 1061 is longer than that of the first scraper 1051. The first baffle 1061 is inclined toward the first cleaning component 31. The first baffle 1061 contacts the surface to be cleaned, further blocking the sewage at the first suction port 101. The first scraper 1051 includes a curved portion 105a and a scraping portion 105b. The curved portion 105a and the groove 110 together form a position for installing the first cleaning component 31. The curved portion 105b and the first baffle 1061 are sandwiched to form the first suction port 101. The diameter of the first suction port 101 from the surface to be cleaned to the height position of the first rotating shaft 310 changes from large to small. The first suction port 101 can cover a larger suction area when it is close to the surface to be cleaned, and the first suction port 101 is clamped between the first scraper 1051 and the first baffle 1061, so that the first suction port 101 has good air tightness, reducing the wind loss of the fan 50, and ensuring that the suction force of the fan sucks the sewage at the first suction port 101 into the storage device 40.

[0057] For other embodiments, see Figure 4B and Figure 4C , Figure 4B is a partial cross-sectional view of the installation position of the second scraper 1052 in one embodiment of the present invention, Figure 4CIt is a schematic diagram of the structure of the second scraper 1052 in an embodiment of the present invention. The cleaning component also includes a second cleaning component 32. The main body 100 is also provided with a second suction port 102. The second cleaning component 32 is attached to the second suction port 102. The second cleaning component 32 is configured to clean the debris on the surface to be cleaned to the second suction port 102. The second cleaning component 32 is a roller brush. The second cleaning component 32 includes a second rotating shaft 320, a brush body 321 and bristles 322 arranged outside the second rotating shaft 320. The brush body 321 and the bristles 322 are both made of elastic material. The outer surface of the brush body 321 is provided with a plurality of slots. The bristles 322 are plugged into the slots. In other embodiments, the bristles 322 can be integrally formed with the brush body 321. The second rotating shaft 320 is connected to a motor installed inside the main body 100. The motor drives the second rotating shaft 320 to rotate, so that the second cleaning component 32 rotates. The bristles 322 clean the debris on the surface to be cleaned to the second suction port 102, and the fan 50 sucks the dirt on the surface to be cleaned into the storage device 40 through the second suction port 102. In order to enable the second cleaning component 32 to better clean the debris to the second suction port 102, the bristles 322 are arranged in a V shape from both ends of the second cleaning component 32 to the middle, and the second suction port 102 is correspondingly arranged at the middle position of the second cleaning component 32. During the rotation and cleaning process of the second cleaning component 32, the debris gathers at the second suction port 102.

[0058] A second scraper 1052 may be provided at the groove 110 where the second cleaning component 32 is installed, and a second baffle 1062 is provided on the rear wall of the second suction port 102. The second baffle 1062 is longer than the second scraper 1052, and the second baffle 1062 is inclined toward the second cleaning component 32. The second baffle 1062 contacts the surface to be cleaned, and further blocks the debris at the second suction port 102. The second scraper 1052 is provided on the front wall of the second suction port 102, and the second scraper 1052 is serrated, and the length of the serrations extends to the bristles 322 and has a certain gap with the brush body 321, so that the second scraper 1052 can comb the bristles 322 on the one hand to prevent the bristles 322 from condensing into lumps, and on the other hand, the second scraper 1052 can push out or cut off the hair or thread-like objects entangled with the bristles 322, so as to improve the cleaning effect of the second cleaning component 32. In other embodiments, the second scraper 1052 can be disposed at other positions of the groove 110 where the second cleaning assembly 32 is installed, and can extend to the bristles 322. It is conceivable that the first cleaning assembly 31 can also be a roller brush to clean debris and other dirt on the surface to be cleaned to the first suction port 101.

[0059] In another embodiment, the cleaning component 30 may include a first cleaning component 31 and a second cleaning component 32 at the same time, wherein the first cleaning component 31 is a rotary mopping component, and the second cleaning component 32 is a roller brush. The first cleaning component 31 is installed on the rear side of the second cleaning component 32, so that when the cleaning robot cleans the surface to be cleaned, it can first sweep the surface to be cleaned, collect debris, and then mop the surface to be cleaned. Of course, in other embodiments, the first cleaning component 31 may be a roller brush, and the second cleaning component 32 may be a rotary mopping component, and the second cleaning component 32 is installed on the front side of the first cleaning component 31.

[0060] The advantage of such a configuration is that the diameter of the first suction port 101 from the ground to the height position of the first rotating shaft 310 changes from large to small, and the first suction port 101 can cover a larger suction area when it is close to the ground, and the first suction port 101 is sandwiched between the first scraper 1051 and the first baffle 1061, which improves the air tightness at the first suction port 101, reduces the wind loss of the fan 50, and ensures that the suction force sucks the sewage at the first suction port 101 into the storage device 40. The scraping portion 105b of the first scraper 1051 at least partially extends to the wiping member 311. During the operation of the cleaning robot, the motor drives the first rotating shaft 310 to rotate, and the first cleaning component 31 rotates to wipe the surface to be cleaned. The first scraper 1051 scrapes the dirt attached to the first cleaning component 31 to the surface to be cleaned. Further, the fan 50 sucks the sewage on the surface to be cleaned into the storage device 40 through the first suction port 101. When the first cleaning component 31 is a roller brush, the bristles of the roller brush can also be combed while cleaning the debris on the surface to be cleaned to prevent the bristles from agglomerating into clumps or being entangled, so as to improve the cleaning effect.

[0061] In other embodiments, the scraper 105 can be configured as a swingable component, which periodically swings to a position in which it is at least partially in contact with the wiping member 312 and / or the bristles 322 to scrape the first cleaning component 31. For example, when the scraper 105 is not in operation, it is in a first position, where the first position is a position in which it is not in contact with the first cleaning component 31. At every time interval, the scraper 105 moves to a second position, where the second position is a position in which the scraper 105 is at least partially in contact with the first cleaning component 31. In another embodiment, the scraper 105 can be controlled to move from the first position to the second position according to the number of revolutions of the first cleaning component 31.

[0062] In another embodiment, the cleaning assembly 30 may include a mounting bracket, which is detachably mounted on the groove 110 of the main body 100, and the scraper 105 is disposed on the mounting bracket. Preferably, the scraper 105 is detachably connected to the mounting bracket, so that after long-term scraping of the cleaning assembly, the scraper 105 is worn and the scraper 105 can be replaced, saving costs while ensuring the cleaning effect of the cleaning assembly 30. The mounting bracket may be provided with a plug interface, and the scraper 105 is provided with a plug-in portion, and the plug-in portion is inserted into the plug interface to fix the scraper 105 on the mounting bracket; of course, the scraper 105 can be integrally formed with the mounting bracket. It is conceivable that the cleaning assembly 30 may only include the first cleaning assembly 31 or the second cleaning assembly 32.

[0063] Second embodiment

[0064] See also Figure 4 , Figure 5 and Figure 6 , Figure 4 yes Figure 3 The cross-sectional view along the AA line. Figure 5 yes Figure 3 The cross-sectional view of the BB line. Figure 6 A cross-sectional view of the positional relationship between the dust box 420, the sewage chamber 412 and the clear liquid chamber 411 in one embodiment of the present invention. The structure and function of the cleaning robot provided in the second embodiment are basically the same as the structure and function of the cleaning robot described in the first embodiment. The difference is that the storage device 40 is installed on the main body 100 and is connected to the first suction port 101 of the main body 100. The storage device 40 may include a bottom shell 43, a middle shell 42 arranged on the upper side of the bottom shell 43, and an upper shell 41 arranged on the upper side of the middle shell 42. The bottom shell 43 and the middle shell 42 are covered to form a dust box 420, and the middle shell 42 and the upper shell 41 are covered to form a water circulation device 410. The water circulation device 410 includes a sewage chamber 411 and a clear liquid chamber 412, and the sewage chamber 411 and the clear liquid chamber 412 are connected through a filter assembly 413, so that the sewage in the sewage chamber 411 is purified by the filter assembly 413 and stored in the clear liquid chamber 412.

[0065] A partition 415 is horizontally arranged in the middle of the water circulation device 410, and the partition 415 is integrally formed with the water circulation device 410 to separate the water circulation device 410 into a sewage chamber 411 and a clear liquid chamber 412, and the sewage chamber 411 is located on the upper side of the clear water chamber 412. In other embodiments, the partition 415 can be arranged in the vertical direction to divide the sewage chamber 411 and the clear liquid chamber 412 in the front-to-back direction, and the partition 415 can be snapped onto the inner wall of the water circulation device 410. The partition 415 is provided with a through opening, and the filter assembly 413 is a filter screen installed at the bottom of the sewage chamber 411, and the filter assembly 413 covers the through opening. In other embodiments, the filter assembly 413 can be snapped onto the through opening at one end and extend to the clear liquid chamber 412 at the other end, and the filter assembly 413 is a mesh-shaped component. The filter assembly 413 may also be provided with a nylon mesh at the opening, and filled with graphene or activated carbon or other materials that can efficiently purify water. The nylon mesh filters the dirt precipitated in the sewage chamber 411, and the turbid water after preliminary filtration enters the filter assembly 413, and after being filtered by the graphene or other filtering components in the filter assembly 413, it becomes clear water and infiltrates into the clear liquid chamber 412. A handle structure may also be provided on the top of the filter assembly 413, so that it can be directly taken out for cleaning.

[0066] The second suction port 102 is a dust suction port, and the second suction port 102 is connected to the dust box 420 through the dust suction channel 421. The first suction port 101 is a sewage suction port, and the first suction port 101 is connected to the sewage chamber 411 through the sewage suction channel 414. The dust suction channel 421 extends obliquely upward from the second suction port 102 to the dust box 420. One end of the sewage suction channel 414 is connected to the first suction port 101, and the other end passes through the clean liquid chamber 412 and communicates with the sewage chamber 411. In order to prevent the sewage in the sewage chamber 411 from seeping out along the sewage suction channel 414 and causing secondary contamination of the surface to be cleaned, the sewage suction channel 414 extends to the upper half of the sewage chamber 411, and a cover body 4110 is provided at the top of the sewage chamber 411 toward the clean liquid chamber 412. The cover body 4110 at least partially extends to the middle of the sewage chamber 411, and the sewage suction channel 414 extends into the cover body 4110. In other embodiments, the cover body 4110 can extend to the bottom of the sewage chamber 411 , and openings are arranged around the cover body 4110 , which can preliminarily filter the sucked sewage so that the sewage is further filtered by the filter component 413 and then stored in the clear liquid chamber 412 .

[0067] In this embodiment, a drain port 512 is provided at the bottom of the clear liquid chamber 412, and the first cleaning component 31 is installed at the lower side of the drain port 512 so as to guide the liquid in the clear liquid chamber 412 to the first cleaning component 31. In other embodiments, a water spray component may be provided at the bottom rear side wall of the clear liquid chamber 412 to spray the liquid in the cleaning chamber 412 onto the surface to be cleaned, and the water spray component may be provided between the first cleaning component 31 and the second suction port 102. The clear liquid chamber 412 may store clean water or cleaning liquid, or the clear liquid chamber 412 may be divided into two independent liquid storage chambers, storing clean water and cleaning liquid respectively. In other embodiments, the storage device 40 may further include a water injection port 416, which is attached to the clear liquid chamber 412 for manually adding clean water or cleaning liquid to the clear liquid chamber 412. The water injection port 416 is disposed at the top of the storage device 40 . The water injection port 416 can be connected to the clear liquid chamber 412 by providing a water injection channel. The water injection port 416 can also be disposed on the side wall of the clear liquid chamber 412 .

[0068] During the operation of the cleaning robot, the second cleaning component 32 rotates to clean the debris on the surface to be cleaned to the second suction port 102, and the fan 50 sucks the debris on the surface to be cleaned into the dust box 420 through the second suction port 102. The first cleaning component 31 is installed on the rear side of the second cleaning component 32, and the first cleaning component 31 further mops and rubs the surface to be cleaned to clean the sewage or fine dust on the surface to be cleaned to the first suction port 101. The fine dust on the surface to be cleaned is very easy to adhere to the surface of the first cleaning component 31. If too much sewage adheres to the first cleaning component 31, its cleaning effect will be affected. The first scraper 1051 scrapes the dirt attached to the first cleaning component 31 to the surface to be cleaned, and can also squeeze the sewage on the first cleaning component 31 and drip it onto the surface to be cleaned. The fan 50 sucks the sewage on the surface to be cleaned into the sewage tank 411 through the first suction port 101. The sewage is filtered by the filter assembly 413 and stored in the clean liquid chamber 412 , and then the clean water in the clean liquid chamber 412 is guided to the first cleaning assembly 31 through the drain port 512 .

[0069] The advantages of such a configuration are: on the one hand, the sewage on the surface to be cleaned can be collected and clean water can be injected into the first cleaning component 31 during the working process, and the first cleaning component 31 can be scraped by the first scraper 1051 in time. While cleaning the surface to be cleaned, the first cleaning component 31 can be cleaned. When working for a long time, the first cleaning component 31 is still relatively clean to ensure the cleaning effect of the surface to be cleaned; on the other hand, the first suction port 101 is clamped between the first scraper 1051 and the first baffle 1061, so that the first suction port 101 has good air tightness, and the fan can more easily collect the debris and sewage on the surface to be cleaned into the dust box 420 and the sewage chamber 411 respectively, and can further filter and purify the sewage collected in the sewage chamber 411 into clean water and store it in the clean liquid chamber 412, and guide the clean water to the first cleaning component 31, so as to realize the recycling of sewage, and there is no need to manually add clean water to the clean liquid chamber 412 in real time.

[0070] Third embodiment

[0071] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 , Figure 6 4 is a cross-sectional view of the positional relationship among the dust collecting box 420, the sewage chamber 412 and the clear liquid chamber 411 in one embodiment of the present invention. Figure 7 is a partial cross-sectional view of a storage device in a transverse direction according to an embodiment of the present invention, Figure 8 is a schematic diagram of the structure of a fan in one embodiment of the present invention, Fig. 9 yes Figure 8 Front view of the fan. The structure and function of the cleaning robot provided in the third embodiment are basically the same as the structure and function of the cleaning robot described in the aforementioned embodiment. The difference is that the fan 50 is attached to the main body 100 and is connected to the storage device 40 through an air duct, and the air duct includes a first air duct 51 connected to the sewage chamber 411 and a second air duct 52 connected to the dust box 420, and the first air duct 51 and the second channel 52 converge at the fan. The main body 100 is also provided with an air outlet 520, and the air outlet 520 is arranged on the side wall of the main body 100. The fan 50 is operable to guide the airflow from the second suction port 102 and the first suction port 101 to the air outlet 520, so as to suck the debris on the surface to be cleaned into the dust box 420 and the sewage on the surface to be cleaned into the sewage chamber 411.

[0072] A first filter 417 is provided at the connection between the sewage chamber 411 and the first air duct 51. When the sewage from the surface to be cleaned is sucked from the first suction port 101 through the sewage suction channel 414 into the sewage chamber 411, the first filter 417 filters the moisture contained in the airflow entering the first air duct 51 to prevent water vapor from entering the fan 50 and damaging the fan motor or other internal components, thereby affecting the air extraction performance of the fan 50. The first filter 417 is to be arranged at a higher position in the sewage chamber 411. The bottom or lower half of the first filter 417 is an airtight entity, and the upper half is an air outlet wrapped with a nylon net.

[0073] A second filter 422 is provided at the connection between the dust box 420 and the second air duct 52. In the process of sucking the debris on the surface to be cleaned from the second suction port 102 into the dust box 420 through the dust suction channel 421, the second filter 422 filters the fine dust or fine ash and other debris contained in the airflow entering the second air duct 52 to prevent the fine dust or fine ash and other debris raised in the dust box 420 from entering the fan 50. The fine dust or fine ash and other debris are very easy to adhere to the fan 53 of the fan 50. The second filter 422 is effectively provided to block the fine dust or fine ash and other debris guided from the second suction port 102 to the air outlet 520, so as to reduce the corrosion of the internal components of the fan 50 and reduce the impact on the air extraction performance of the fan 50. The second filter 422 is a wrinkle filter or other component that can filter fine ash or fine dust and other debris.

[0074] In other embodiments, see Figure 8 and Fig. 9 In order to reduce the noise during the operation of the fan 50, the structure of the fan 53 can be used. The noise of the fan 53 is usually composed of rotation noise and eddy noise. Rotation noise is caused by the blades of the fan periodically cutting the air, generating aerodynamic pulsation. It has the blade path frequency as the fundamental frequency and is accompanied by higher harmonics. Eddy noise is a broadband aerodynamic noise. The rotation of the blades causes the surrounding air to vortex, forming a Karman vortex street. The laminar layer on the surface of the blade separates when the leeward side of the blade approaches the free end, causing the air to be disturbed, forming a gas compression and dilution process, thereby forming eddy noise.

[0075] The fan 53 includes: an impeller seat 531 with a circular periphery, a hub 532 disposed at the center of the impeller seat 531, a plurality of inner blades 533 and outer blades 534; the plurality of inner blades 533 are evenly distributed on the circumference of the hub 532 in a radial shape, each inner blade 533 is bent in the same direction with a preset arc, and the inner blades 533 do not extend to the circular periphery of the impeller seat 531. The outer blades 534 extend from between two adjacent inner blades 533 to the circular periphery of the impeller seat 531, and are evenly distributed in a radial shape, and each outer blade 534 is bent in the direction toward which the inner blades 533 are directed with a certain arc. The outer blade 534 extending from between two adjacent inner blades 533 means that the outer blade 534 and the inner blade 533 are staggered and have overlapping parts. A more intuitive and vivid way to describe the overlapping parts between the outer blade 534 and the inner blade 533 is that the distance D1 from the center CC of the impeller seat 531 to the top of the inner blade 533 away from the hub 532 is smaller than the distance D2 from the center CC of the impeller seat 531 to the top of the outer blade 534 close to the hub 532. Since the outer blade 534 and the inner blade 533 have overlapping parts, a pressure relief channel 535 is formed between an adjacent outer blade 534 and an inner blade 533. In actual applications, the fan 53 is moved along the inner blade 533. Figure 8 When rotating in the direction indicated by the hollow arrow, a small amount of airflow on the windward side 5331 of the inner blade 533 flows into the leeward side 5342 of the outer blade 534 through the pressure relief channel 535, so that the fluid velocities on the windward side 5341 and the leeward side 5342 of the outer blade 534 approach the same, thereby reducing the generation of Karman vortices and thus reducing eddy noise.

[0076] The advantage of such a configuration is that by providing a fan 50, the airflow at the second suction port 102 and the first suction port 101 can be guided to the air outlet 520, and the debris cleaned by the second cleaning component 32 and the sewage cleaned by the first cleaning component 31 can be further sucked into the dust box 420 and the sewage chamber 411 through the dust suction channel 421 and the sewage suction channel 414 respectively. The first suction port 101 is sandwiched between the scraper 105 and the second baffle 106, and has good air tightness, which reduces the wind loss of the fan 50 and improves the cleaning effect. In addition, the structure of the fan blades of the fan 53 is cleverly arranged, which effectively reduces the noise of the fan 50.

[0077] Fourth embodiment

[0078] See also Fig.10 , Fig. 10A , Fig. 10B and Fig.11 , Fig.10 is a cross-sectional view of the connection relationship between the liquid cleaning chamber 412 and the first cleaning component 31 in one embodiment of the present invention; Fig. 10A yes Fig.10 A partial enlarged view of part II. Fig. 10B is a partial cross-sectional view of the installation position of the cone 5123 in one embodiment of the present invention, Fig.11 Schematic diagram of the drain port 512 in one embodiment of the present invention. The structure and function of the cleaning robot provided in this embodiment are substantially the same as those of the cleaning robot described in the previous embodiment. The difference is that a drain port 512 is further provided at the bottom of the clean liquid chamber 412, and the main body 100 is provided with a drainage channel 104 connecting the drain port 512 and the first cleaning component 31 to guide the cleaning liquid in the clean liquid chamber 412 to the first cleaning component 31.

[0079] The drainage channel 104 includes a first water diversion channel 1041 and a second water diversion channel 1042. The first water diversion channel 1041 is connected to the first water diversion port 5121. The water flowing out of the drainage port 512 flows into the first water diversion channel 1041 through the first water diversion port 5121. The water in the first water diversion channel 1041 flows evenly to the left and right directions and flows into the second water diversion port 5122. From the second water diversion port 5122, it flows into the second water diversion channel 1042. In the second water diversion channel 1042, the water flows evenly to the left and right directions again and flows into the water distribution port 5123. In order to facilitate the collection of sewage, the suction force of the first suction port 101 corresponding to the middle position of the first cleaning component 31 is the largest. In this embodiment, the water distribution port 5123 is set to five. The water output of the water distribution ports 5123 corresponding to the left and right ends of the first cleaning component 31 is half of the water output of the three middle water distribution ports 5123, which can effectively prevent the sewage from overflowing from both ends of the first cleaning component 31 and causing pollution at the edge of the cleaning area.

[0080] In other embodiments, only the first water diversion channel 1041 may be provided, that is, the water flowing out of the drain port 512 flows into the first water diversion channel 1041 through the first water diversion port 5121, and flows evenly to the left and right in the first water diversion channel 1041. The left and right ends of the first water diversion channel 1041 are respectively provided with water distribution ports 5123, and the water flowing out of the drain port 512 is evenly divided into two halves and arranged to the first cleaning component 31. In this solution, the number of water distribution ports 5123 is twice the number of drain ports 512. It can be imagined that in other embodiments, the number of water diversion channels and water distribution ports can be set according to actual conditions.

[0081] In this embodiment, the drain port 512 is circular and made of soft rubber material, with a cross break line 5125 in the middle, so that water cannot leak out when the storage device 40 is not installed in the cleaning robot. After the storage device 40 is installed in the cleaning robot, the first water diversion port 5121 is placed in the drain port 512 to push the cross break line 5125 to open a hole, and the water flowing out of the clean water drain port 512 in the clean liquid chamber 412 flows into the first water diversion channel 1041 through the first water diversion port 5121, and finally distributes the water to the first cleaning component 31 from the water distribution port 5123.

[0082] See also Fig. 10B In order to make the amount of water flowing from the drain port 512 into the water diversion channel 1041 in the left and right directions more uniform, a conical member 5123 may be provided at the position of the drain port 512. When the water in the clean water chamber 412 flows out from the drain port 512, the conical member 5123 evenly divides the outflowing water into two halves, which flow to the left and right directions of the first water diversion channel 1041. Correspondingly, a conical member 5123 may also be provided at the water diversion port 5121.

[0083] For other embodiments, see Fig.12 , Fig.12 4 is a cross-sectional view of the connection between the clean water chamber 412 and the first cleaning assembly 31 in another embodiment of the present invention. A water pump 513 and a one-way valve 514 can be provided to control the amount of clean water in the clean water chamber 412 flowing into the first cleaning assembly 31.

The structure and function of the cleaning robot provided in this embodiment are basically the same as the structure and function of the cleaning robot described in the previous embodiment. The difference is that in this embodiment, the layout of the dust box 420 for collecting debris, the sewage chamber 414 for collecting sewage from the surface to be cleaned, and the clean liquid chamber 412 for storing cleaning liquid included in the storage device 40 is different. Please refer to Fig.10, the sewage chamber 411 is arranged on the upper side of the dust box 420, the clean liquid chamber 412 is arranged on the rear side of the dust box 420, the sewage chamber 411 and the clean liquid chamber 412 are connected by setting a connecting pipe 418, one end of the connecting pipe 418 is connected to the bottom of the sewage chamber 411, and the other end is connected to the side wall of the clean liquid chamber 412, or the other end is connected to the top of the clean liquid chamber 412, and the filter assembly 413 is installed at the connection between the connecting pipe 418 and the sewage chamber 411. The advantage of this arrangement is that no other storage space is set at the top of the clean liquid chamber 412, and the water injection port can be directly opened at the top of the clean liquid chamber 412. When liquid needs to be added to the clean liquid chamber 412, the water injection port can be directly opened to add it, without removing the storage device 40 from the cleaning robot and then adding it. In other embodiments, the dust box 420 can also be arranged on the front side of the water circulation device 40.
