[0070] The present inventors have made a detailed study on the sewage tank or sewage box and other sewage containing devices for containing sewage on the equipment, and found that in order to have a good sewage suction capacity, most of the current sewage containing devices are box bodies with good sealing performance. Although it is beneficial to suck the sewage from the sewage collecting device into the sewage containing device, the sewage containing device cannot balance with the atmospheric pressure outside, so an automatic exhaust structure needs to be installed in the sewage containing device to balance the internal pressure of the sewage containing device with the atmospheric pressure outside, at which time the sewage can flow out of the sewage containing device. The automatic exhaust structure not only occupies the internal space of the sewage containing device, reduces the sewage containing capacity of the sewage containing device, and has a complex structure and high cost. Due to the good sealing performance of the sewage collecting device, it cannot be opened, so it is inevitable that long-term sewage storage will cause dirt inside the sewage containing device. Long-term dirt will breed bacteria and produce odor.

[0071] Based on the above problems, the present inventors try to open a vent hole at the top of the sewage containing device to balance the atmospheric pressure inside and outside the sewage containing device, to ensure good sewage discharge effect, to cancel the automatic exhaust structure, to simplify the structure of the sewage containing device, to expand the internal volume of the sewage containing device, and to reduce the cost. If the vent hole is too large, the sewage in the sewage containing device will overflow through the vent hole during the movement of the cleaning equipment. Therefore, the diameter of the vent hole is set to be relatively small, which can not only balance the air pressure but also avoid the sewage overflow as much as possible. However, the speed of sewage discharge and the volume of air entering the vent hole are the same during the sewage discharge process of the sewage containing device, so the sewage discharge process is relatively slow. At this time, the inventors use the suction device to suck air into the sewage containing device to increase the amount of air entering the sewage containing device and to accelerate the speed of sewage discharge. In addition, the present inventors set the sewage containing device to be openable, so that the user can disassemble the sewage containing device from the body after a period of use to clean the internal structure, to ensure that the sewage containing device does not contain dirt, to avoid bacterial breeding, to avoid odor, etc. The following is a specific embodiment.

[0072] The present utility model will be further described in detail in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, but not to limit the present utility model.

[0076] Please refer to Figure 1 And Figure 5As shown, the present application provides a cleaning robot, which comprises a body 3, a moving assembly and a cleaning assembly. The moving assembly is located at the bottom of the body 3 and can drive the cleaning robot to move autonomously. The cleaning assembly is arranged on the body 3 and abuts against the surface to be cleaned, so as to clean the surface to be cleaned. The cleaning process can be wet cleaning, dry cleaning or a combination of wet cleaning and dry cleaning, so as to ensure good cleaning effect. Here, the wet cleaning refers to a cleaning mode in which a cleaning implement is wetted with liquid, such as mopping or wiping, and the dry cleaning refers to a cleaning mode in which a dry cleaning implement is used to clean the surface to be cleaned, such as dusting or sweeping. In order to ensure good cleaning effect of the cleaning assembly, a scraper and a sewage collecting device 31 are usually arranged on the side of the cleaning implement capable of wet cleaning. The scraper can scrape the sewage on the cleaning implement and drop it into the sewage collecting device 31, so as to ensure the cleanliness of the cleaning implement, ensure that the surface abutting against the surface to be cleaned is always adhered with clean water instead of gradually dirty sewage, and ensure good cleaning effect.

[0077] The cleaning robot of the present application includes but is not limited to a mopping robot, a sweeping and mopping integrated robot, a window wiping robot and the like, as long as it is a robot with wet cleaning function.

[0078] Please refer to Figures 1-6 As shown, it can be understood that the sewage collecting device 31 is only used to collect the sewage scraped from the cleaning implement, and thus is only a temporary storage device for sewage. Therefore, the volume of the sewage collecting device 31 is relatively small, so as to avoid occupying too much space inside the cleaning robot. In order to avoid too much water stains remaining on the surface to be cleaned during the wet cleaning process of the cleaning robot on the surface to be cleaned, so that the surface to be cleaned can dry faster, and to avoid the sewage not being adsorbed in time by the cleaning implement remaining on the surface to be cleaned, an adsorption port is usually arranged on the bottom of the body 3 and faces the surface to be cleaned. The cleaning device further comprises a sewage containing device 1 and a suction device 2. The adsorption port, the sewage collecting device 31 and the suction device 2 are all in communication with the sewage containing device 1 through pipelines. The suction device 2 can provide suction force to the sewage containing device 1, so that negative pressure is generated inside the sewage containing device 1, thereby sucking the liquid or dust on the surface to be cleaned at the adsorption port and the sewage in the sewage collecting device 31 into the sewage containing space 113 in the sewage containing device 1, so as to realize long-time storage of the sewage. Here, the sewage containing device 1 can be a sewage bucket, a sewage box or a sewage tank and the like, as long as it can store sewage for a long time.

[0079] Since the volume of the sewage containing device 1 is limited, a water level detector 14 is usually arranged in the sewage containing device 1. When the water level reaches the highest water level line of the sewage containing device 1, the cleaning robot or the user can be prompted that the sewage containing device 1 is full and needs to be discharged. Please refer to Figures 1-6As shown, in order to facilitate the rapid discharge of sewage, the sewage outlet 111 is usually arranged at the lowest point of the bottom wall of the sewage containing space 113. A sealing plug is arranged at the sewage outlet. The sealing plug can be an electric sealing valve or a plug that needs to be manually inserted and pulled out. If the sealing plug is a plug that needs to be manually inserted and pulled out, the user needs to manually open the plug to pour out the sewage after dismounting the sewage containing device 1 from the body 3. If it is an electric sealing valve, the electric sealing valve can be controlled to be opened to automatically discharge the sewage into the base station or the sewer after the cleaning robot returns to the base station. The sealing plug will not be explained in detail in this application. As long as it can achieve the purpose of plugging the sewage outlet without water leakage or opening the sewage outlet.

[0080] Please refer to Figures 1-6 As shown, the sewage inlet 107 in the sewage containing space 113 which is in communication with the adsorption port and the sewage collecting device 31 pipeline is usually arranged above the highest water level line of the sewage containing device 1 to ensure that the sewage can fall to the inside of the sewage containing space 113 under the action of its own gravity after entering the sewage containing space 113 and prevent the sewage in the sewage containing space 113 from overflowing from the sewage inlet 107. In some embodiments of the present application, the sewage inlet 107 can be arranged at the highest position of the side wall of the sewage containing space 113 and face the sewage containing space 113. Alternatively, a permeable sewage inlet pipe column 114 can be arranged on the bottom wall of the sewage containing space 113 and face the top wall of the sewage containing space 113. The height of the sewage inlet pipe column 114 exceeds the highest water level line, and the sewage inlet 107 is located at the top end of the sewage inlet pipe column 114 and faces the top wall of the sewage containing space 113. When the sewage in the sewage containing device is shaken, the sewage needs to be shaken to a height above the sewage inlet pipe column 114 and fall into the sewage inlet 107 to cause the sewage to overflow from the sewage inlet 107. When the sewage inlet 107 is arranged on the side wall of the sewage containing space 113 and faces the sewage containing space 113, the sewage can easily overflow from the sewage inlet 107 when it is shaken. Therefore, the sewage inlet pipe column 114 is arranged, and the sewage inlet 107 is arranged at the top end of the sewage inlet pipe column 114 and faces the top wall of the sewage containing space 113, which is more difficult for the sewage to overflow from the sewage inlet 107. The structure of the sewage inlet 107 located at the top end of the sewage inlet pipe column 114 will be further described below.

[0081] In order to further prevent the sewage from overflowing from the sewage inlet 107, please refer to Figures 1-6As shown, in some embodiments of the present application, an anti-overflow cap is arranged above the sewage inlet 107. After the sewage passes through the sewage inlet 107, it flows into the sewage containing space 113 through the gap between the anti-overflow cap and the top end of the sewage inlet pipe column 114. The anti-overflow cap not only has the effect of preventing sewage from overflowing from the sewage inlet 107, but also has the function of preventing the upward spatter of sewage, so as to avoid the problem that the spattered sewage encounters the blockage of the top wall of the sewage containing space 113 and spatters around, and to avoid the problem that the spattered sewage enters the pipeline connected with the suction device 2, causing damage to the suction device 2.

[0082] Further, please refer to Figures 1-6 As shown, in some embodiments of the present application, the sewage inlet pipe column 114 is arranged on one side of the sewage containing space 113 along the length direction. A partition plate 123 is arranged on the side of the sewage inlet pipe column 114 away from the space wall of the sewage containing space 113. The partition plate 123 is arranged on the top wall of the containing space, and the bottom end of the partition plate 123 exceeds the sewage inlet 107. The partition plate 123 and the three side walls of the sewage containing space 113 form a frame shape, and surround the circumferential side of the sewage inlet 107, so as to prevent the spatter phenomenon of the sewage entering from the sewage inlet 107 to the surrounding.

[0083] Based on the above structural design of the sewage inlet 107 and the sewage inlet pipe column 114, similarly, the bottom wall of the sewage containing space 113 is provided with a permeable air suction pipe column 112 toward the top wall of the sewage containing space 113. The top end of the air suction pipe column 112 exceeds the highest water level line of the sewage containing space 113, and the air suction port 102 is arranged at the top end of the air suction pipe column 112 toward the top wall of the sewage containing space 113. This can not only meet the requirement of suction of air, but also can place the sewage into the air suction port 102.

[0084] Further, please refer to Figures 1-6 As shown, in order to prevent the sewage from entering the air suction port 102, in some embodiments of the present application, a waterproof air ventilation structure 122 is arranged on the top wall of the sewage containing space 113, and covers the air suction port 102. The waterproof air ventilation structure 122 can block the sewage exceeding the height of the air suction pipe column 112 caused by the shaking of the sewage, so as to avoid the sewage entering the air suction port 102 during the falling process of the sewage. It is explained here that since the waterproof air ventilation structure 122 covers the circumferential side of the air suction port 102, the range is relatively small. Even if there is sewage below the air suction port 102 in the waterproof air ventilation structure 122, when the sewage in the sewage containing space 113 shakes due to the bumping or turning of the sweeping robot, the shaking degree of the sewage in the waterproof air ventilation structure 122 is far less than that of the sewage outside the waterproof air ventilation structure 122. Therefore, the sewage can be prevented from entering the air suction port 102.

[0085] Specifically, in some embodiments of the present application, please refer to Figures 1-6As shown, the waterproof and air ventilation structure 122 includes the fence column 103, the enclosing column 104, the enclosing frame 105, and the air outlet passage 106, wherein the bottom end of the fence column 103 abuts against or contacts the top end of the air suction pipe column 112, and the plurality of fence columns 103 are uniformly and spacedly arranged on the circumference of the air suction port 102, the enclosing column 104 is arranged on the circumference of the air suction pipe column 112, the enclosing frame 105 is arranged on the circumference of the enclosing column 104, the air outlet passage 106 is arranged on one side of the enclosing frame 105 and has an included angle with the enclosing frame 105, and the air outlet passage 106 is in communication with the inside of the enclosing frame 105. The double-layered enclosing of the enclosing column 104 and the enclosing frame 105 can play a double role of resisting the fluctuation of the sewage, so that the sewage on the circumference of the fence column 103 cannot be lifted to the top end of the air suction pipe column 112 due to the fluctuation, and the fence column 103 can prevent the sewage from splashing into the air suction port 102. It can be understood that the more the fence columns 103 are and the smaller the gap between the fence columns 103 is, the less favorable the air flow is, so in some embodiments of the present application, there are two fence columns 103, one on each side of the air suction port 102, which can effectively prevent the sewage from entering and ensure a sufficient gap for the air flow. The air outlet passage 106 is arranged on one side of the enclosing frame 105 and has an angle, such as an acute angle or an obtuse angle, with the enclosing frame 105, which is not only favorable for the air flow, but also can prevent the sewage from flowing into the enclosing frame 105 when the sewage container 1 shakes, and can weaken the impact of the sewage when it flows into the air outlet passage 106 due to the included angle between the air outlet passage 106 and the direction of the sewage fluctuation, thereby preventing splashing.

[0086] Generally, in order to make the sewage more easily enter the sewage containing space 113, the air suction pipe column 112 and the sewage inlet pipe column 114 are generally arranged at two ends along the length direction of the sewage containing space 113, so that a negative pressure can be better formed in the sewage containing space 113 during the sewage suction, and the sewage entering from the sewage inlet port 107 can be prevented from splashing into the air suction port 102, but generally, due to the layout of various parts on the main machine, the suction device 2 is arranged on the side close to the sewage inlet pipe column 114, which can cause the pipeline between the suction device 2 and the air suction pipe column 112 to be relatively long, the pipeline is prone to bending and affecting the suction effect, and the pipeline can be blocked after a long time.

[0087] To solve the above problems, please refer to Figures 1-6As shown, in some embodiments of the present application, the air extraction column 112 is located in the middle of the length direction of the pollution container 1, which not only shortens the distance between the suction device 2 and the air extraction column 112, making the pipeline shorter and less likely to bend, thereby ensuring good suction function, but also because the amplitude of the two ends of the pollution space 113 is greater than the amplitude of the middle in the state of jolting, the sewage in the middle is relatively stable and less likely to impact the waterproof vent structure 122, thereby being less likely to enter the air extraction port 102.

[0088] Although the pollution space 113 is set to be isolated from the outside, which can be beneficial to the suction function of the suction device 2, but it will also cause the atmospheric pressure in the pollution space 113 to be unbalanced with the outside, which will lead to the situation that the sewage cannot flow out of the pollution outlet 111 during the pollution process, therefore, most of the pollution containers 1 currently have an automatic exhaust mechanism, but the automatic exhaust mechanism not only occupies the volume of the pollution space 113, but also leads to the situation that the structure of the pollution container 1 is complex.

[0089] Therefore, in some embodiments of the present application, please refer to Figures 1-6 As shown, the top wall of the pollution space 113 has a vent hole 121 communicating with the outside, the gas flow of the vent hole 121 is less than the gas flow of the air extraction port 102, that is, the diameter of the vent hole 121 is less than the diameter of the air extraction port 102, so that the volume of the gas extracted during the operation of the suction device 2 is still greater than the volume of the air entering from the vent hole 121, which can still apply suction force to the pollution space 113, so that negative pressure is generated in the pollution space 113, and when the sewage is sucked into the pollution space 113, the air pressure in the pollution space 113 can be balanced with the atmospheric pressure outside through the vent hole 121, so that the sewage can be discharged even without an automatic exhaust mechanism.

[0090] Further, the diameter of the vent hole 121 cannot be too large, otherwise it will cause the sewage to overflow from the vent hole 121 during the jolting process of the pollution container 1, therefore, in some embodiments of the present application, the diameter of the air extraction port 102 is greater than or equal to 4 times the diameter of the vent hole 121, which has little effect on the suction force, so as to balance the air pressure in the pollution space 113 and the outside, and ensure the smooth pollution.

[0091] During the pollution process, due to the action of atmospheric pressure, the volume of the sewage flowing out is consistent with the volume of the air entering the vent hole 121, and the diameter of the vent hole 121 is relatively small, so the speed of the sewage discharging is relatively slow, when fast pollution is needed, the suction device 2 can be fully utilized, the suction device 2 is turned on, and air is sucked into the containing space through the suction port and the sewage collecting device 31, so that the atmospheric pressure in the pollution space 113 is greater than or equal to the atmospheric pressure outside, thereby promoting the effect of sewage discharge.

[0092] Generally, sewage will be discharged through the sewage outlet 111 into the sewer or the sewage tank of the base station, and in the process of cleaning the cleaning robot cleaning the surface to be cleaned, there are not only sewage but also large and small solid waste, hair, etc. If the solid waste is discharged from the sewage outlet 111 along with the sewage, it is likely to block the sewage outlet 111 or the sewer or the sewage pipe connected to the sewage tank of the base station.

[0093] Therefore, in some embodiments of the present application, please refer to Figures 1-6 As shown in the figure, the sewage outlet 111 is located on the side of the air suction pipe column 112 away from the sewage inlet pipe column 114, and the sewage containing space 113 is also provided with a filter assembly 124, which is located between the partition plate 123 and the waterproof ventilation structure 122, or in other words, between the air suction pipe column 112 and the sewage inlet pipe column 114. The filter assembly 124 can block solid particles in the sewage, preventing solid waste or hair from passing through, not only preventing solid waste and hair from flowing out of the sewage outlet 111 along with the sewage, but also preventing solid waste and hair from entering the air suction port 102 due to the shaking of the sewage and causing the air suction port 102 to be blocked.

[0094] Further, in some embodiments of the present application, please refer to Figures 1-6 As shown in the figure, in the direction from the sewage inlet pipe column 114 to the air suction pipe column 112, the filter assembly 124 includes at least two filter grid groups 108 and a detachable filter screen 109. At least one filter grid group 108 is arranged on the bottom wall of the sewage containing space 113, and at least one filter grid group 108 is arranged on the top wall of the sewage containing space 113. The filter size of the filter grid group 108 is larger than that of the filter screen 109. The filter grid group 108 can block the passage of solid waste with a relatively large size, and arranging part of the filter grid group 108 on the bottom wall and the other part on the top wall can achieve the effect of avoiding the passage of solid waste from top to bottom, ensuring good filtering and blocking effect. The filter screen 109 can filter out solid waste or hair with a smaller size, achieving better filtering effect. Double-layer graded filtering not only reduces the situation that the filter assembly 124 is blocked by solid waste and hair, but also achieves better filtering effect, preventing the sewage outlet 111 from being blocked.

[0095] In some embodiments of the present application, please refer to Figures 1-6As shown, the filter grid group 108 includes a plurality of grids uniformly spaced along the width direction of the containing space, and the spacing between two adjacent grids on the filter grid group 108 gradually decreases along the direction from the inlet pipe column 114 to the air outlet pipe column 112, that is, the filter size of the filter grid group gradually decreases along the direction from the inlet pipe column 114 to the air outlet pipe column 112, so as to ensure that the filter grid can gradually filter out more solid waste of different sizes, while slowing down the situation that the filter grid is blocked by solid waste. It can be understood that the more filter grids occupy the space in the sewage containing space 113, the worse the sewage containing capacity of the sewage containing space 113, so in the embodiment of the present application, the number of filter grid groups 108 is only two to ensure greater sewage containing capacity. Of course, in other embodiments, the number of filter grid groups 108 can be more than two, which is not limited in the present application.

[0096] Although the filter grid group 108 and the filter screen 109 can achieve the filtering effect of sewage, they are easy to be blocked if they are planar, so in some embodiments of the present application, the filter grid group 108 and the filter screen 109 are arc-shaped and protrude toward the air outlet pipe column 112, which increases the area of contact with sewage compared with the planar structure, so that the blocking situation is less likely to occur.

[0097] Long-term filtration and containing sewage will inevitably cause dirt to remain in the containing space, which will not only breed bacteria but also cause the filter screen 109 to be blocked over a long period of time. Therefore, in some embodiments of the present application, the sewage containing device 1 includes a box body 11 and a rotatable cover 12 provided at the top end of the box body 11, the box body 11 has a sewage containing space 113, the box cover 12 opens the sewage containing space 113, and the box cover 12 closes the sewage containing space 113. The box cover 12 is the top wall of the sewage containing space 113, and the bottom wall of the box body 11 is the bottom wall of the sewage containing space 113. After the cleaning equipment works for a period of time, the sewage containing device 1 can be removed from the machine body 3, and the box body 11 and the box cover 12 can be cleaned. Not only can it prevent dirt from accumulating in the box cover 12 to breed bacteria and produce odor, but also it can clean the filter assembly 124 blocked by solid waste and hair to ensure good filtering effect.

[0098] Because the filter screen 109 has relatively fine mesh, it is not easy to clean after being blocked, so in some embodiments of the present application, please refer to Figures 1-6 As shown, the filter screen 109 is detachably arranged in the containing space, and the containing space is provided with a sliding groove 116 on both sides along the width direction, and the two side edges of the filter screen 109 are slidably arranged in the sliding groove 116, so that when the filter screen 109 is blocked, the filter screen 109 can be taken off the sewage containing device 1 for separate cleaning, which not only facilitates user operation and cleaning, but also can be cleaned more thoroughly.

[0099] In some embodiments of the present application, in order to prevent the filter screen 109 from moving back and forth in the chute 116 and affecting the filtering effect, the top end of the accommodation space, that is, the box cover 12 is provided with abutting pieces 125, a plurality of abutting pieces 125 are arranged at intervals, and the bottom end of the abutting piece 125 abuts against the top end of the filter screen 109 when the box cover 12 is buckled on the box body 11, so as to limit the position of the filter screen 109 and ensure that the filter screen 109 will not be displaced.

[0100] Generally, the overall rigidity of the filter screen 109 will not be too high, in order to avoid deformation of the filter screen 109, in some embodiments of the present application, please refer to Figures 1-6 As shown in the figure, the bottom end of the dirt containing space 113 is provided with a limiting column 115 towards the top end of the dirt containing space 113, the limiting column 115 is located on the side of the filter screen 109 away from the air suction pipe column 112, and the limiting column 115 is connected with the middle part of the filter screen 109, which can limit the position of the middle part of the filter screen 109 and provide further support for the filter screen 109, so as to ensure that the filter screen 109 is always in the preset arc shape and ensure good filtering effect.

[0101] In some embodiments of the present application, please refer to Figures 1-6 Figures 1-6 As shown in the figure, the dirt containing device 1 further comprises a sealing piece 13, the bottom end of the box cover 12 is provided with a sealing table towards the accommodation space, the sealing piece 13 is arranged around the outer periphery of the sealing table, when the box cover 12 is covered on the box body 11, the side of the sealing piece 13 away from the sealing table abuts against the side wall of the dirt containing space 113, and the sealing piece 13 is in a compressed state. Thus, the sealing property of the dirt containing space 113 is ensured when the box cover 12 is buckled on the box body 11, and good adsorption property is ensured when the sewage is sucked.

[0102] Application scenario one:

[0103] When the water level detector 14 detects that the sewage in the dirt containing space 113 has reached the highest water level line during the cleaning process of the cleaning robot, the dirt containing device 1 is full, at this time, the height of the sewage inlet is higher than the full sewage height of the dirt containing space, the cleaning robot automatically drives back to the base station, after the cleaning robot is docked with the base station, the electric sealing valve is opened, and the sewage is discharged from the dirt containing device 1 to the base station. At this time, since the cleaning robot has not completed the cleaning work on the surface to be cleaned, it is necessary to quickly discharge the sewage, so that the suction device 2 is started at the same time when the electric sealing valve is opened, so as to quickly suck air into the dirt containing space 113 to promote the discharge of the sewage. When the sewage is discharged, the electric sealing valve and the suction device 2 are closed at the same time, and the cleaning robot drives to the last cleaning position to continue the subsequent cleaning work on the surface to be cleaned.

[0104] Application scenario two:

[0105] When the cleaning robot returns to the base station to charge after cleaning the surface to be cleaned, the user finds that the cleaning robot has finished cleaning, and the user has not cleaned the dirt container 1 for a long time, so the user decides to clean the dirt container 1. At this time, the user can remove the dirt container 1 from the body 3 of the cleaning robot, align the drain opening 111 with the sewer opening, open the sealing plug at the drain opening 111, and open the box cover 12. At this time, the sewage in the box body 11 can be quickly discharged from the drain opening 111. Then the user can take out the filter screen 109, and clean the dirt container 1 and the filter screen 109 respectively. When the cleaning of the dirt container 1 and the filter screen 109 is completed, the filter screen 109 is put back into the box body 11, the box cover 12 is buckled, and finally the dirt container 1 is put back into the cleaning robot.
