DETAILED DESCRIPTION

[0119] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0120] Referring to Figures 1 to 6 , a cleaning tank structure 100 according to an embodiment of the present application includes a cleaning tank 10, a water outlet 26, a filter 54, and a rib 14. The water outlet 26 communicates with the cleaning tank 10, and the filter 54 is housed within the water outlet 26 to filter waste. The rib 14 is located within the cleaning tank 10. The cleaning tank structure 100 is configured such that when a mop 11 is placed on the rib 14, the rib 14 scrapes the mop 11 during relative motion between the rib 14 and the mop 11. At least a portion of the inner surface of the cleaning tank 10 is in direct contact with the mop 11. Furthermore, during relative motion between the cleaning tank 10 and the mop 11, the mop 11 applies a cleaning force to the inner surface of the cleaning tank 10, thereby achieving self-cleaning of the cleaning tank 10. The relative motion between the rib 14 and the mop 11 can be either rotational motion of the rib 14 relative to the mop 11 while the mop 11 is stationary, or rotational motion of the mop 11 relative to the rib 14 while the rib 14 is stationary. Alternatively, both the ribs 14 and the mop 11 can rotate, and their rotation directions can be opposite, to improve cleaning efficiency. The relative motion between the cleaning tank 10 and the mop 11 can be either the cleaning tank 10 rotating relative to the mop 11 while the mop 11 is stationary, or the mop 11 rotating relative to the cleaning tank 10 while the cleaning tank 10 is stationary. Alternatively, both the cleaning tank 10 and the mop 11 can rotate, and their rotation directions can be opposite, to improve cleaning efficiency. The inner surface of the cleaning tank 10 includes a bottom surface 101 of the cleaning tank 10 and an inner peripheral surface (i.e., the sidewalls of the cleaning tank 10) surrounding the outer periphery of the bottom surface 101.

[0121] The cleaning force can be the contact force and / or squeezing force applied when the mop 11 is in direct contact with the inner surface of the cleaning tank 10 when the cleaning tank and the mop generate relative motion. The cleaning force can also be the force applied to the inner surface of the cleaning tank 10 during the liquid flow process when the mop 11 stirs the liquid (such as clean water, a mixture of clean water and cleaning liquid), or the cleaning force exerted on the inner surface of the cleaning tank 10 when the mop drives the water flow (such as the water flow driven by the mop when it rotates) to the inner surface of the cleaning tank 10, thereby achieving self-cleaning of the cleaning tank 10 while cleaning the mop 11, avoiding the odor of the cleaning tank structure 100 or reducing the chance of the odor of the cleaning tank structure 100.

[0122] In the above-mentioned cleaning tank structure 100, when the mop 11 is placed on the ridges 14, at least a portion of the inner surface of the cleaning tank 10 is in direct contact with the mop 11. Therefore, when the ridges 14 clean the mop 11, as the cleaning tank 10 and the mop 11 generate relative motion, the mop 11 applies a cleaning force to the inner surface of the cleaning tank 10 to achieve self-cleaning of the cleaning tank 10. That is, the mop 11 can clean the inner surface of the cleaning tank 10, thereby avoiding or reducing the amount of debris remaining on the inner surface of the cleaning tank 10, thereby avoiding or reducing the chance of the cleaning tank structure 100 stinking.

[0123] Specifically, when the mop 11 rotates relative to the washing tank 10, it applies a cleaning force to the inner surface of the washing tank 10, achieving self-cleaning of the washing tank 10. Thus, the rotating mop 11 applies a cleaning force to the inner surface of the washing tank 10, achieving self-cleaning of the washing tank 10. Specifically, the rotating mop 11 cleans the inner surface of the washing tank 10, thereby preventing or reducing debris remaining on the inner surface of the washing tank 10, thereby preventing or reducing the chance of odor in the washing tank structure 100. The mop 11 is driven to rotate by the cleaning robot.

[0124] Specifically, the cleaning robot includes a body and a mop 11, which can be mounted on the bottom of the body. In this embodiment, the mop 11 rotates with its axis of rotation substantially perpendicular to the bottom of the body. It should be understood that when the cleaning robot is operating normally outside the station, the axis of rotation of the mop 11 is substantially perpendicular to the ground. When the cleaning robot is inside the station, the lowest point of the mop 11 is in front of the cleaning tank 10 near the base station 200, and the highest point of the mop 11 is behind the cleaning tank 10 near the base station 200.

[0125] In Figure 4, the cleaning tank 10 is shaped like a circle and can accommodate a circular mop 11, allowing the mop 11 to be cleaned in the cleaning tank 10. A cleaning tank 10 similar to a circle can also accommodate a triangular mop 11. It will be appreciated that in one embodiment, while the center of rotation of the mop 11 remains unchanged, the cleaning tank 10 can be configured to be similar to a circle to accommodate the mop 11, regardless of whether the mop 11 is triangular, quadrilateral, or other polygonal. In another embodiment, while the center of rotation of the mop 11 varies, the cleaning tank 10 can be an irregular shape, but still accommodate the mop 11, allowing the mop 11 to be cleaned in the cleaning tank 10.

[0126] When the cleaning tank structure 100 is provided with a single cleaning tank 10, it can be used in combination with a cleaning robot having a single mop 11. The single mop 11 can rotate in the cleaning tank 10 in a clockwise direction R1 or a counterclockwise direction R2. This application does not make any specific restrictions on this.

[0127] If the cleaning tank structure 100 is provided with two cleaning tanks 10 along the length direction L of the cleaning tank structure 100, it can be used in conjunction with a cleaning robot having two mops 11. The two mops 11 placed in the two cleaning tanks 10 can rotate in the same or different directions during cleaning. For example, in conjunction with Figure 6, in one embodiment, the mop 11 placed in the left cleaning tank 10 can rotate in the clockwise direction R1, and the mop 11 placed in the right cleaning tank 10 can rotate in the counterclockwise direction R2. In one embodiment, the mop 11 placed in the left cleaning tank 10 can rotate in the counterclockwise direction R2, and the mop 11 placed in the right cleaning tank 10 can rotate in the clockwise direction R1. This application does not make any specific restrictions on this. The length direction L includes the left and right directions.

[0128] When the mop 11 of the cleaning robot needs to be cleaned, the cleaning robot can enter the base station 200, and the mop 11 can be placed on the ridges 14. The cleaning robot can drive the mop 11 to rotate, so that the ridges 14 and the mop 11 move relative to each other, and the ridges 14 scrape and clean the mop 11.

[0129] In one embodiment, when the mop 11 is placed on the ridges 14, while the ridges 14 scrape and clean the mop 11, the rotating mop 11 can directly contact the contact area 16 on the inner surface of the cleaning tank 10. In the process of cleaning the mop 11, the rotating mop 11 can also clean the contact area 16, thereby avoiding or reducing the amount of debris remaining on the bottom surface 101 of the cleaning tank 10, thereby avoiding or reducing the chance of the cleaning tank structure 100 stinking.

[0130] In Figure 1 , along the vertical direction H of the cleaning tank structure 100, the vertical direction H of the cleaning tank structure 100 includes the height direction and the up-down direction. Optionally, in one embodiment, the entire bottom surface 101 of the cleaning tank 10 can be the contact area 16, that is, the entire bottom surface 101 of the cleaning tank 10 is in direct contact with the rotating and non-rotating mop 11.

[0131] Optionally, referring to FIG. 4 , the ridges 14 extend radially along the cleaning tank 10 . Thus, the ridges 14 are longer and have a larger contact area with the mop 11 , thereby improving the scraping effect on the mop 11 .

[0132] Optionally, the ridges 14 are connected to the cleaning tank 10 as an integral structure, thereby reducing the cost and increasing the rigidity of the cleaning tank structure 100. For example, the cleaning tank structure 100 can be integrally manufactured using an injection molding process, with the ridges 14 connected to the cleaning tank 10 as an integral structure.

[0133] The illustrated cleaning tank structure 100 is provided with two cleaning tanks 10 and can be adapted to cleaning robots with dual turntable mops. A mop 11 can be provided at the bottom of each turntable mop. Rotating the turntable mop can drive the mop 11 to rotate, and the rotation axis of the mop 11 is substantially perpendicular to the bottom of the body. When the two mops 11 are cleaning, the rotation directions of the two mops 11 can be the same or opposite, which is not specifically limited in this application. During the cleaning process of the cleaning robot, the rotation directions of the two mops 11 can be the same or opposite. It is understood that in other embodiments, the cleaning tank structure 100 can also be provided with a single cleaning tank 10, which can be adapted to cleaning robots with a single turntable mop.

[0134] Optionally, in Figure 1 , the mop 11 may have an opening near the center of the mop 11. Optionally, in other embodiments, the mop 11 may not have an opening near the center of the mop 11.

[0135] Referring to FIG. 1 and FIG. 2 , in some embodiments, the inner surface of the cleaning tank 10 includes a bottom surface 101 , and the bottom surface 101 includes at least one of a contact area 16 and a non-contact area 18 . The cleaning tank structure 100 is configured as follows:

[0136] The contact area 16 is in direct contact with the mop 11 so that the mop 11 applies a cleaning force to the contact area. Specifically, the contact area 16 is in direct contact with the mop 11 when it is rotating or not rotating.

[0137] In the above-mentioned cleaning tank structure 100, when the mop 11 is placed on the ridges 14, the contact area 16 can directly contact the mop 11. Therefore, during the cleaning process of the mop 11, when the cleaning tank 10 and the mop 11 generate relative motion, the mop 11 can clean the contact area 16, thereby avoiding or reducing the amount of debris remaining on the bottom surface 101 of the cleaning tank 10, thereby preventing or reducing the chance of the cleaning tank structure 100 odorizing.

[0138] When the mop 11 is placed on the ridge 14 , the vertical distance between the non-contact area 18 and the plane where the mop 11 is located is in the range of (0, 3] mm.

[0139] In this way, during the process of cleaning the mop 11, when the mop 11 is placed on the ridges 14, the mop 11 can drive the water flow to the non-contact area 18 during rotation to clean the non-contact area 18. At the same time, the non-contact area 18 is increased, and the friction between the mop 11 and the bottom surface 101 of the cleaning tank 10 can be reduced, thereby reducing energy consumption and being adaptable to low-power motors.

[0140] Specifically, in one embodiment, when the mop 11 is placed on the ridges 14, the bottom surface 101 of the cleaning tank 10 further includes a non-contact area 18. While the ridges 14 are scraping the mop 11, the vertical distance W between the non-contact area 18 of the bottom surface 101 of the cleaning tank 10 and the plane on which the mop 11 is located is in the range of (0, 3] mm. During the mop cleaning process, the rotation of the mop can drive water to the non-contact area to clean the non-contact area. For example, the vertical distance W between the non-contact area 18 of the bottom surface 101 of the cleaning tank 10 and the plane on which the mop 11 is located can be 3 mm, 2.8 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, or other values ​​less than or equal to 3 mm. The vertical distance W between the non-contact area 18 of the bottom surface 101 of the cleaning tank 10 and the mop 11 can be determined based on actual needs and is not specifically limited in this application.

[0141] Optionally, in the embodiment shown in Figure 3, the mop 11 includes fluff 12 and a chassis 13, the fluff 12 is arranged at the bottom of the chassis 13, and the vertical distance W between the non-contact area 18 of the bottom surface 101 of the cleaning tank 10 and the plane where the mop 11 is located can be the vertical distance between the non-contact area 18 and the fluff 12.

[0142] Alternatively, in FIG23 , the contact area 16 may be an inclined surface, and the non-contact area 18 may also be an inclined surface, with the slope of the non-contact area 18 being greater than the slope of the contact area 16. In FIG24 , the contact area 16 may be a horizontal surface, and the non-contact area 18 may also be a horizontal surface. In FIG25 , the contact area 16 may be a horizontal surface, and the non-contact area 18 may be an inclined surface. In FIG26 , the contact area 16 may be an inclined surface, and the non-contact area 18 may be a horizontal surface. In FIG27 , the contact area 16 may be an inclined surface, and the non-contact area 18 may also be an inclined surface, with the slope of the non-contact area 18 being equal to the slope of the contact area 16. The contact area 16 may be a curved or arcuate surface, and the non-contact area 18 may also be a curved or arcuate surface.

[0143] Please refer to Figure 33. It can be seen from the effect diagram that when the vertical distance W between the non-contact area 18 and the mop 11 is in the range of (0,3] mm, even in the area where the mop 11 does not contact the bottom surface 101 of the cleaning tank 10, the rotating mop 11 can still have the desired cleaning effect on the non-contact area 18, reducing the chance of the cleaning tank structure 100 stinking.

[0144] Specifically, in Figure 33, y represents the vertical extrusion amount between the mop 11 and the bottom surface 101 of the cleaning tank 10, in mm. When y<0, it means that the mop 11 is isolated from the bottom surface 101 of the cleaning tank 10. At this time, the absolute value of y represents the isolation amount (i.e., the vertical distance W). F represents the cleaning effect of the cleaning robot after one self-cleaning. In each test, 5g of yellow mud is sprinkled on the ground. After the cleaning robot returns to the station and undergoes a self-cleaning, the weight z (in g) of the increased dirt in the cleaning tank 10 is weighed, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0145] Figure 33 shows that when y >= -3 (i.e., when the vertical distance W is in the range of (0, 3] mm), the cleaning effect F >= 90%, meeting the cleaning requirements. When -3 <= y < 0, the rotation of the mop 11 drives the water in the cleaning tank 10, flushing the tank 10 and thus cleaning it. When y > 0, the mop 11 squeezes against the bottom 101 of the tank 10. The friction between the mop 11 and the bottom 101 ensures that the cleaning effect meets the requirements. Because the mop 11 is composed of a base 13 and pile 12, and the base 13 is a hard material that is difficult to squeeze, the vertical squeeze between the mop 11 and the bottom 101 of the tank 10 cannot reach the thickness of the mop 11. The test data is shown in Table 1 below. The smaller the z, the less yellow mud remains in the tank 10, and the better the cleaning effect.

[0146] Table 1

[0147] 4 , 10 , 20 and 31 , in some embodiments, the cleaning tank structure 100 includes a base 20 , in which the cleaning tank 10 is disposed.

[0148] In this way, the base 20 can provide an installation structure for the cleaning tank structure 100 , facilitating the installation of the cleaning tank structure 100 .

[0149] Specifically, in the embodiment shown in FIG4 , the base 20 may be shaped like a long disk. The cleaning tank structure 100 may be mounted on the base station 200 via the base 20. Two cleaning tanks 10 are provided on the base 20. The side walls of the two cleaning tanks 10 may be connected, and the two cleaning tanks 10 are interconnected, thereby allowing the two cleaning tanks 10 to share a water outlet 26. Each cleaning tank 10 may also be provided independently. Two ridges 14 are provided within each cleaning tank 10, and the two ridges 14 are symmetrically arranged. Optionally, the base 20 may be connected to the cleaning tank 10 and the ridges 14 to form an integral structure.

[0150] Please refer to Figure 1a and Figure 22. In some embodiments, the cleaning tank structure 100 includes a water inlet hole 24 and a water outlet hole 26. The bottom surface 101 of the cleaning tank 10 connects the water inlet hole 24 and the water outlet hole 26. The bottom surface 101 of the cleaning tank 10 is inclined along the water inlet hole 24 toward the water outlet hole 26. The bottom surface 101 of the cleaning tank 10 is conical, and the non-contact area 18 includes at least a portion of the circular area T0. The circular area T0 is a circular area formed with the center O of the bottom surface 101 of the cleaning tank 10 as the center of the circle and a preset radius.

[0151] Therefore, the bottom surface 101 of the cleaning tank 10 can be formed in a conical shape, and the cleaning effect requirement of the non-contact area 18 can be met.

[0152] Specifically, the conical bottom surface 101 of the cleaning tank 10 is inclined along the water inlet 24 toward the water outlet 26, and the lowest point of the bottom surface 101 of the cleaning tank 10 is the position connected to the water outlet 26. When the mop 11 is placed in the cleaning tank 10, the mop 11 is separated from at least a portion of the circular area.

[0153] In Figure 1a, the left cleaning tank 10 is used as an example for illustration. Since circular area T0 is a circular area formed with a predetermined radius and centered at the center O of the bottom surface 101 of the cleaning tank 10, and since the bottom surface 101 of the cleaning tank 10 is conical, the circular area T0 in the middle of the bottom surface 101 of the cleaning tank 10 is located lower than the edge of the bottom surface 101 of the cleaning tank 10. Compared to the edge of the bottom surface 101 of the cleaning tank 10, the circular area T0 forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the non-contact area 18 and meeting the cleaning effect requirements. It can be understood that the predetermined radius of the circular area T0 is smaller than the radius of the cleaning tank 10.

[0154] Optionally, in FIG1a , the mop 11 has an opening in the middle, and the bottom surface 101 of the cleaning tank 10 exposed by the opening can also be cleaned by the water flow thrown out by the rotating mop 11 or the fluff 12 of the mop 11, thereby meeting the cleaning effect requirements. Optionally, in other embodiments, the mop 11 may not have an opening in the middle.

[0155] The preset radius can be specifically limited according to needs, and this application does not make any specific limitations on this.

[0156] In some embodiments, the ridges 14 divide the bottom surface 101 of the cleaning tank 10 into a first bottom surface area 101a and a second bottom surface area 101b;

[0157] The non-contact area 18 includes one or a combination of a first non-contact area 181 and a second non-contact area 182. The first non-contact area 181 is a portion of a first circular area T1. The first circular area T1 is a circular area formed with a center O of the first bottom area 101a and a first predetermined radius.

[0158] The second non-contact area 182 is a portion of a second circular region T2 . The second circular region T2 is a circular region formed with the center of the second bottom region 101 b as the center O and with a second predetermined radius.

[0159] Thus, the bottom surface 101 of the cleaning tank 10 can be divided into areas by using the ridges 14 , and the first bottom surface area 101 a and the second bottom surface area 101 b can be configured separately to meet the cleaning effect requirements of the non-contact area 18 .

[0160] Optionally, the ridge 14 may be fixed in the cleaning tank 10 or may be detachably connected to the bottom surface of the cleaning tank 10 .

[0161] Optionally, in Figure 1a, two ridges 14 are provided in the cleaning tank 10, which divide the bottom surface 101 of the cleaning tank 10 into a first bottom surface area 101a and a second bottom surface area 101b. In Figure 1a, the first bottom surface area 101a is the front bottom surface area, and the second bottom surface area 101b is the rear bottom surface area.

[0162] Alternatively, the non-contact area 18 includes a combination of the first non-contact area 181 and the second non-contact area 182. Alternatively, the non-contact area 18 includes the first non-contact area 181 or the second non-contact area 182.

[0163] The first bottom surface area 101a is a portion of the first conical bottom surface, and the second bottom surface area 101b is a portion of the second conical bottom surface. Optionally, in FIG1a , the radius of the circle containing the first bottom surface area 101a is greater than the radius of the circle containing the second bottom surface area 101b. Optionally, the radius of the circle containing the first bottom surface area 101a is less than or equal to the radius of the circle containing the second bottom surface area 101b.

[0164] The first non-contact area 181 is a portion of the first circular area T1. Since the first circular area T1 is a circular area formed with the center O of the first bottom area 101a and a first predetermined radius, and the first bottom area 101a is a portion of a conical bottom surface, the first circular area T1 in the center of the first bottom area 101a is positioned lower than the edge of the first bottom area 101a. Compared to the edge of the first bottom area 101a, the first circular area T1 forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the first non-contact area 181 and meeting the cleaning effect requirements. It can be understood that the first predetermined radius is smaller than the radius of the first bottom area 101a.

[0165] The second non-contact area 182 is a portion of the second circular area T2. Since the second circular area T2 is a circular area formed with the center O of the second bottom area 101b and a second predetermined radius, and the second bottom area 101b is a portion of the conical bottom surface, the second circular area T2 in the middle of the second bottom area 101b is located lower than the edge of the second bottom area 101b. Compared to the edge of the second bottom area 101b, the second circular area T2 forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the second non-contact area 182 and meeting the cleaning effect requirements. It can be understood that the second predetermined radius is smaller than the radius of the second bottom area 101b.

[0166] Optionally, in FIG1a , the first preset radius and the second preset radius are equal, and the center of the first circular area T1 coincides with the center of the second circular area T2 (at the location of the center O in FIG1a ). It will be appreciated that in other embodiments, the first preset radius and the second preset radius may not be equal, and the center of the first circular area T1 may not coincide with the center of the second circular area T2.

[0167] Optionally, the number of the protruding strips 14 in the cleaning tank 10 is not limited to two, and may be a single strip or more than two strips.

[0168] 1 to 3 , in some embodiments, the range of the amount of compression between the mop 11 and the bottom surface 101 of the cleaning tank 10 is [0, T) mm, where T is the thickness of the mop 11 .

[0169] In this way, the amount of squeezing between the mop 11 and the bottom surface 101 of the cleaning tank 10 meets the cleaning effect requirements.

[0170] Specifically, the thickness T of the mop 11 includes the length V2 of the fluff 12 and the thickness V3 of the chassis 13. The range of the amount of compression between the mop 11 and the bottom surface 101 of the cleaning tank 10 is [0, T) mm, where T is the thickness of the mop 11. The greater the amount of compression between the mop 11 and the bottom surface 101 of the cleaning tank 10, the greater the friction between the mop 11 and the bottom surface 101 of the cleaning tank 10, and the better the cleaning effect. It should be noted that when the amount of compression between the mop 11 and the bottom surface 101 of the cleaning tank 10 is close to the thickness T of the mop 11, the friction between the mop 11 and the bottom surface 101 of the cleaning tank 10 is relatively large. At this time, the mop 11 is still within the range of rotation (that is, the motor of the cleaning robot can still drive the mop 11 to rotate), which will not affect the cleaning of the mop 11.

[0171] In some examples, the amount of compression between the mop 11 and the bottom surface 101 of the washing tank 10 can be 0 mm, (1 / T) mm, (2 / T) mm, (3 / T) mm, (4 / T) mm, (5 / T) mm, or other values ​​within the range [0, T), which is not specifically limited in this application. A compression of 0 mm between the mop 11 and the bottom surface 101 of the washing tank 10 indicates that the contact surface between the fluff 12 and the bottom surface 101 of the washing tank 10 is not compressed.

[0172] 1 and 2 , in some embodiments, the cleaning tank structure 100 is configured such that when the mop 11 is placed in the cleaning tank 10 , the horizontal distance between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0, 8] mm.

[0173] In this way, the water carried by the mop 11 is thrown to the side wall of the cleaning tank 10 under the action of centrifugal force, thereby cleaning the side wall of the cleaning tank 10.

[0174] Specifically, when the mop 11 is placed in the cleaning tank 10 and rotated on the ridges 14 for cleaning, the edge of the mop 11 can maintain a certain horizontal distance from a portion of the side wall of the cleaning tank 10 (the front side wall of the cleaning tank 10 as shown in FIG2 ). The horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0, 8] mm. For example, the horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 can be 8 mm, 7.8 mm, 7.5 mm, 6 mm, 5.5 mm, 5 mm, or other values ​​less than 8 mm. The horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 can be determined based on actual needs and is not specifically limited in this application.

[0175] When the horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0,8] mm, when the mop 11 rotates and cleans on the ridges 14, the water carried by the mop 11 is thrown to the side wall of the cleaning tank 10 under the action of centrifugal force, and the water can clean the side wall of the cleaning tank 10, thereby achieving the cleaning of the side wall of the cleaning tank 10. In addition, when the horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0,8] mm, it is also convenient for the cleaning robot to place the mop 11 in the cleaning tank 10, and it is easy to position it.

[0176] Please refer to Figure 34. It can be seen from the effect diagram that when the horizontal distance U between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0,8] mm, even if the edge of the mop 11 does not contact the side wall of the cleaning tank 10, the rotating mop 11 can still have the desired cleaning effect on the non-contact side wall area of ​​the cleaning tank 10, reducing the chance of the cleaning tank structure 100 stinking.

[0177] Specifically, in Figure 34, x represents the horizontal extrusion amount between the edge of the mop 11 and the side wall of the cleaning tank 10 (if there is a baffle 22, it is the side of the baffle 22 facing the cleaning tank 10), and the unit is mm. When x<0, it means that the edge of the mop 11 and the side wall of the cleaning tank 10 are isolated. The absolute value of x represents the isolation amount, that is, the horizontal distance U. F represents the cleaning effect of the cleaning robot after one self-cleaning. Each test is carried out on the ground with 5g of yellow mud. After the cleaning robot returns to the station and undergoes a self-cleaning, it is weighed to see the weight z (in g) of the increased dirt in the cleaning tank 10, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0178] In this test, the y value was fixed, for example, set to y = 1mm. As shown in Figure 34, when -8 <= x <= 10, the cleaning effect F was >= 90%, meeting the cleaning requirements. When x < -8, the distance between the sidewalls of the tank 10 and the edge of the mop 11 was too great. The rotating mop 11, relying on the water flow and the fluff 12, could not reach the sidewalls, resulting in a blind spot and poor cleaning performance. When x > 10, the mop 11 was excessively squeezed against the sidewalls, causing it to bulge, partially separating from the bottom 101 of the tank 10. This significant separation affected the cleaning effect. The test data is shown in Table 2 below.

[0179] Table 2 (y = 1 mm (1 / 6.5 of the mop thickness))

[0180] 2 , in some embodiments, the cleaning tank structure 100 is configured such that when the mop 11 is placed in the cleaning tank 10 , the amount of extrusion between the edge of the mop 11 and the sidewall of the cleaning tank 10 is in the range of (0,10] mm.

[0181] In this way, the amount of pressure between the edge of the mop 11 and the side wall of the cleaning tank 10 can achieve the desired cleaning effect.

[0182] Specifically, when the mop 11 is placed in the cleaning tank 10 and rotated on the ridges 14 for cleaning, the edge of the mop 11 may be pressed against a portion of the side wall of the cleaning tank 10 (the rear side wall of the cleaning tank 10 as shown in FIG2 ). Optionally, the amount of pressure between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0, 10] mm. For example, the amount of pressure between the edge of the mop 11 and the side wall of the cleaning tank 10 can be 10 mm, 9.8 mm, 9.5 mm, 9 mm, 8.5 mm, 8 mm, or other values ​​less than 10 mm. The amount of pressure between the edge of the mop 11 and the side wall of the cleaning tank 10 can be determined based on actual needs and is not specifically limited in this application.

[0183] The range of the amount of extrusion between the edge of the mop 11 and the side wall of the cleaning tank 10 is (0, 10] mm. When the extrusion between the mop 11 and the side wall of the cleaning tank 10 reaches the maximum amount, the friction between the mop 11 and the side wall of the cleaning tank 10 is the largest, which is conducive to the mutual cleaning between the edge of the mop 11 and the side wall of the cleaning tank 10. It should be noted that when the maximum extrusion between the edge of the mop 11 and the side wall of the cleaning tank 10 is in the range of (0, 10] mm, the mop 11 can still rotate (that is, the motor of the cleaning robot can still drive the mop 11 to rotate), and will not cause the motor to overload and will not affect the cleaning of the mop 11.

[0184] Optionally, the vertical squeezing amount of the mop 11 is fixed, and the maximum compression amount and the maximum isolation amount between the mop 11 and the side wall of the cleaning tank 10 in the horizontal direction are explored.

[0185] Please refer to Figure 35. Since the vertical extrusion of the mop 11 is more important for the cleaning effect, when the vertical extrusion of the mop 11 is relatively large (close to the critical value, y = 6.0mm, the extrusion is equal to the thickness of the mop 11 6.0 / 6.5), when the mop 11 meets the cleaning requirements, the horizontal x range is explored, and whether the y value has an impact on the x range that meets the cleaning requirements is explored.

[0186] Figure 35 shows that when y = 6.0 mm, the cleaning effect F is >= 90% when -8 <= x <= 10, meeting the cleaning requirements. Comparing this with Table 1, we find that the y value has no significant effect on the x range that meets the cleaning requirements. Because the y value primarily affects the vertical cleaning effect, once the y value meets the cleaning requirements, it has no significant impact on the effective x value. The test data is shown in Table 3 below.

[0187] Table 3 (y=6.0 mm) (mop thickness 6.0 / 6.5)

[0188] Optionally, when the mop 11 and the side wall of the cleaning tank 10 reach the maximum squeezing amount, and the mop 11 and the bottom surface 101 of the cleaning tank 10 reach the maximum squeezing amount, the mop 11 can still rotate (that is, the motor of the cleaning robot can still drive the mop 11 to rotate), and will not cause the motor to overload and will not affect the cleaning of the mop 11 rotation.

[0189] It should be noted that the test data is the data obtained by taking the average value after multiple tests in which the thickness of the mop 11 is 6.5 mm.

[0190] In some embodiments, the cleaning tank structure 100 includes a barrier bar 22 , which surrounds the cleaning tank 10 , and the distance between the edge of the mop 11 and the side wall of the cleaning tank 10 is the distance between the edge of the mop 11 and the barrier bar 22 .

[0191] In this way, the cleaning tank 10 can be enclosed by the blocking bars 22, and the structure is simple.

[0192] Specifically, the cleaning tank structure 100 can be provided with multiple baffles 22, and the multiple baffles 22 can surround the cleaning tank 10, so that when the mop 11 is placed in the cleaning tank 10 for cleaning, the baffles 22 can block water in the cleaning tank 10 and prevent water from flowing out to other areas outside the cleaning tank 10.

[0193] Optionally, the blocking strip 22 may be made of hard rubber (such as ABS, PC and other materials) or soft rubber (such as TPU, silicone and other materials).

[0194] Optionally, referring to FIG. 10 , the cleaning tank 10 may be formed by a first recess 130 provided on the top surface of the base 20 , and the sidewalls of the cleaning tank 10 may be the sidewalls of the first recess 130 .

[0195] Please refer to Figures 4 and 5. In some embodiments, the cleaning tank structure 100 includes a water inlet hole 24 and a water outlet hole 26. A plurality of protrusions 14 are provided in the cleaning tank 10. The plurality of protrusions 14 and the bottom surface of the cleaning tank 10 form a water supply channel 28. The water supply channel 28 connects the water inlet hole 24 and the water outlet hole 26.

[0196] In this way, the water inlet 24 can deliver clean water through the water supply channel 28 , and at the same time, the sewage after cleaning can be discharged from the water outlet 26 through the water supply channel 28 .

[0197] Specifically, in FIG4 , along the width direction D of the washing tank structure 100, the water inlet 24 can be located on one side of the width and near the rear side of the base 20. The water outlet 26 can be located near the front side of the base 20 in the width direction D. The width direction includes the front-to-back direction. Compared to the water supply channel 28, the water inlet 24 is located higher, while the water outlet 26 is located lower. Water entering from the water inlet 24 can flow to the water outlet 26 through the water supply channel 28 under the action of gravity.

[0198] In Figure 4 , two ridges 14 and the bottom surface of the cleaning tank 10 form a water channel 28. In one embodiment, the mop 11 can rotate on the ridges 14. During rotation, the mop 11 is soaked with clean water in the water channel 28. The ridges 14 scrape and clean the soaked mop 11. After scraping, dirty water, stains, and other debris can flow through the water channel 28 into the water outlet 26, allowing the dirty water to be drained through the water outlet 26. It is understood that in other embodiments, the water channel 28 can be formed not only by two ridges 14 and the bottom surface of the cleaning tank 10, but also by three, four, or another number of ridges 14 and the bottom surface of the cleaning tank 10, without specific limitation herein.

[0199] Furthermore, in Figure 4 , along direction D, the water supply channel 28 can separate the cleaning tank 10 into a front tank 30 and a rear tank 34. The front tank 30 is located near the front side of the base 20, and the rear tank 34 is located near the rear side of the base 20. The bottom surface of the front tank 30 is a first bottom surface area 101a, and the bottom surface of the rear tank 34 is a second bottom surface area 101b. The front tank 30 and the protrusions 14 near the front tank 30 form a first opening 32. The bottom surface of the front tank 30 can connect to the top of the water outlet 26. The protrusions 14 near the front tank 30 scrape the mop 11. After scraping, dirty water and other debris can fall into the front tank 30 and finally flow into the water outlet 26 through the first opening 32. The bottom surface of the rear groove 34 can be connected to the top of the water outlet 26, and the protrusion 14 close to the rear groove 34 scrapes the mop 11. After scraping, sewage and other debris can fall into the rear groove 34 and finally flow into the water outlet 26.

[0200] 19 and 20 , in some embodiments, at least one of the two ridges 14 that enclose the water supply channel 28 has a first notch 36 , and the first notch 36 connects the water supply channel 28 and the cleaning tank 10 .

[0201] In this way, sewage and other debris in the cleaning tank 10 can enter the water supply channel 28 through the first gap 36 and then flow into the water outlet 26 for discharge.

[0202] Specifically, in Figure 19, two ridges 14 are symmetrically arranged in the cleaning trough 10, and a first notch 36 is provided in the middle of each ridge 14. When the mop 11 rotates and cleans in the cleaning trough 10, wastewater and other debris may fall into the cleaning trough 10 on both sides of the water supply channel 28. By providing the first notch 36, the first notch 36 is connected to the water supply channel 28, allowing wastewater and other debris in the cleaning trough 10 to enter the water supply channel 28 through the first notch 36 and then flow to the water outlet 26 for drainage, thereby preventing accumulation in the cleaning trough 10.

[0203] 19 , in some embodiments, among the two ridges 14 that enclose the water supply channel 28 , at least one ridge 14 has a through hole 38 at one end near the water outlet 26 , and the through hole 38 connects the water supply channel 28 and the cleaning tank 10 .

[0204] In this way, sewage and other debris in the cleaning tank 10 can be further discharged into the water supply channel 28 through the through hole 38 .

[0205] Specifically, each of the two ridges 14 has a through-hole 38 at one end near the water outlet 26. The through-hole 38 can be provided along the direction of the water supply channel 28 and can be rectangular in shape. When the mop 11 rotates and washes in the cleaning tank 10, wastewater and other debris can fall into the cleaning tank 10 on both sides of the water supply channel 28. By providing the through-hole 38, the through-hole 38 is connected to the water supply channel 28, thereby further allowing wastewater and other debris in the cleaning tank 10 to enter the water supply channel 28 through the through-hole 38 and then flow to the water outlet 26 for drainage, thereby preventing accumulation in the cleaning tank 10.

[0206] The shape and number of the through holes 38 on the convex strip 14 are not specifically limited. In other embodiments, the shape of the through holes 38 can be set to other shapes, and the number can also be set to multiple.

[0207] In some embodiments, the ridges 14 are inclined toward the water supply channel 28 .

[0208] In this way, the angle formed between the protrusion 14 and the bottom surface of the cleaning tank 10 outside the water supply channel 28 can be made larger, thereby avoiding debris remaining at the angle due to a smaller angle.

[0209] Specifically, in FIG4 , the two protrusions 14 can be tilted toward the water supply channel 28, and the angle θ formed between the protrusions 14 and the bottom surface of the cleaning tank 10 can be an obtuse angle. When the mop 11 is cleaning in the cleaning tank 10, debris after cleaning may remain at the angle formed by the protrusions 14 and the bottom surface of the cleaning tank 10. By tilting the two protrusions 14 toward the water supply channel 28, the angle formed between the protrusions 14 and the bottom surface of the cleaning tank 10 outside the water supply channel 28 can be larger, thereby avoiding debris remaining at the angle due to a smaller angle.

[0210] Please refer to Figures 14 to 16. In some embodiments, the water supply channel 28 includes a first section channel 40 and a second section channel 42. The first section channel 40 and the second section channel 42 are connected in sequence along the direction from the water inlet hole 24 to the water outlet hole 26. Compared with the water inlet hole 24, the depth of the second section channel 42 is greater than or equal to the depth of the first section channel 40.

[0211] In this way, the depth of the second channel 42 is relatively deep, thereby preventing the mop 11 from causing secondary contamination in the second channel 42 .

[0212] Specifically, the water supply channel 28 includes a connecting channel section 44, which is arranged obliquely between the first channel section 40 and the second channel section 42. The first channel section 40, the connecting channel section 44, and the second channel section 42 are sequentially connected along the direction from the water inlet 24 to the water outlet 26. The depth of the connecting channel section 44 along the direction from the water inlet 24 to the water outlet 26 can be greater than or equal to the depth of the first channel section 40, and the depth of the second channel section 42 can be greater than or equal to the depth of the connecting channel section 44.

[0213] Alternatively, in one embodiment, the connecting section channel 44 may be omitted, and the first section channel 40 may be directly connected to the second section channel 42 , as shown in FIG. 16 .

[0214] In one embodiment, when the mop 11 rotates so that the ridges 14 scrape and clean the mop 11, the fluff 12 of the mop 11 can be located in the first section channel 40, and the clean water in the first section channel 40 can clean the fluff 12 of the mop 11. The sewage after cleaning can flow to the second section channel 42 through the connecting section channel 44. The depth of the second section channel 42 is deeper, so that the mop 11 or the fluff 12 of the mop 11 cannot contact the sewage in the second section channel 42, thereby avoiding secondary pollution caused by the mop 11 in the second section channel 42.

[0215] Furthermore, the ridges 14 can scrape debris (solid waste such as particulate matter, thread-like objects, sticky materials, debris, etc.; liquid waste such as sewage) attached to the mop 11 into the water supply channel 28. The water in the water supply channel 28 then flows rapidly out of the water outlet 26 (which is equipped with a filter element 54 to filter out the waste), thereby effectively scraping the waste at high speed and preventing it from being scraped onto other areas of the bottom 101 of the cleaning tank 10. Where the water flow is slower, the waste could accumulate and repeatedly rub against the bottom of the mop 11, damaging it and slowing down the cleaning process, thus reducing cleaning efficiency. By limiting the depth of the second channel 42 to be greater than or equal to the depth of the first channel 40, when the mop 11 is located on the second channel 42, the ridges 14 contact the mop 11, but the water does not, thus preventing secondary contamination of the mop 11.

[0216] The depth of the first channel 40 refers to the vertical distance from a point on the ridge 14 to the bottom of the first channel 40. The depth of the second channel 42 refers to the vertical distance from a point on the ridge 14 to the bottom of the second channel 42.

[0217] Optionally, the first section channel 40 may include multiple first sub-segment channels with different depths and connected end to end, the second section channel 42 may include multiple second sub-segment channels with different depths and connected end to end, the depth of the second section channel 42 may be the average depth of the second sub-segment channels, and the depth of the first section channel 40 may be the average depth of the first sub-segment channels.

[0218] In some embodiments, along the direction from the water inlet 24 to the water outlet 26 , the depth of the first section of the channel 40 gradually increases, and the depth of the second section of the channel 42 gradually increases.

[0219] In this way, along the water inlet to water outlet direction, the mop 11 is less likely to come into contact with the sewage in the channel.

[0220] Specifically, in one embodiment, along the direction from the water inlet hole 24 to the water outlet hole 26, the depth of the first section of the channel 40 at the end away from the water inlet hole 24 is greater than the depth of the end of the first section of the channel 40 near the water inlet hole 24, and the depth of the first section of the channel 40 gradually increases from the end near the water inlet hole 24 to the end away from the water inlet hole 24. In one embodiment, along the direction from the water inlet hole 24 to the water outlet hole 26, the depth of the second section of the channel 42 at the end near the water outlet hole 26 is greater than the depth of the end of the second section of the channel 42 away from the water outlet hole 26, and the depth of the second section of the channel 42 gradually increases from the end away from the water outlet hole 26 to the end near the water outlet hole 26, thereby making it less likely for the mop 11 to come into contact with the sewage in the channel.

[0221] Referring to Figures 14 to 16 , in certain embodiments, first channel section 40 includes a first end 46 and a second end 48, and second channel section 42 includes a third end 50 and a fourth end 52. First end 46 communicates with water inlet 24, second end 48 communicates with third end 50, and fourth end 52 communicates with water outlet 26. A depth H1 of first end 46 ranges from [1, 5] mm, a depth H2 of second end 48 and third end 50 ranges from [2, 8] mm, and a depth H3 of fourth end 52 ranges from [5, 15] mm, with H1 <= H2 <= H3.

[0222] In this way, by determining the depth range of each end of the first section channel 40 and the second section channel 42 , it can be further ensured that the mop 11 is not likely to come into contact with the sewage in the channel.

[0223] Specifically, in one embodiment, the first end 46 is connected to the water inlet 24, the second end 48 is connected to the third end 50, and the fourth end 52 is connected to the water outlet 26, so that water can be discharged into the water outlet 26. Then, by setting the depth H1 of the first end 46 to a range of [1, 5] mm, the depth H2 of the second end 48 and the third end 50 to a range of [2, 8] mm, and the depth H3 of the fourth end 52 to a range of [5, 15] mm, so that H1<=H2<=H3, it is further ensured that the mop 11 is not easily exposed to the sewage in the channel.

[0224] The depth H1 of the first end 46 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or another value between 1 mm and 5 mm.

[0225] The depth H2 of the second end 48 and the third end 50 may be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or another value between 2 mm and 8 mm.

[0226] The depth H3 of the fourth end 52 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, or other values between 5 mm and 15 mm.

[0227] Combined with FIG. 16, the mop 11 from the depth H1 of the first end 46 to the depth H2 of the second end 48 needs to ensure that the mop 11 can contact the water in the water supply channel 28, and the mop 11 cannot completely block the water supply channel 28. The mop 11 at the depth H3 of the fourth end 5 is required to ensure that it does not contact the sewage in the water supply channel 28. The values of H1, H2, and H3 are related to the height L1 of the rib 14, the squeezing amount y of the mop 11 and the bottom surface 101 of the cleaning tank 10 in the vertical direction, and the water flow height M in the water supply channel 28.

[0228] The gap L0 between the mop 11 and the top of the water supply channel 28 = H1 - L1 - y; for H1 = L1 + y + L0, to satisfy that the mop 11 can be wetted by water at H1 and does not block the water supply channel 28, it is necessary to satisfy 0 < L0 < M, that is, L1 + y < H1 < M + L1 + y; similarly for H2, it is necessary to satisfy L1 + y < H2 < M + L1 + y; for H3, it is required that the mop 11 does not contact the sewage in the water supply channel 28, that is, L0 > M, that is, H3 > L1 + y + M, and it is required that H1 < H2 < H3. When L1 = 1, y = 2, M = 3 (unit: millimeter), 3 < H1 < 6, 3 < H2 < 6; H3 > 6. According to different parameters of L1, y, and M, the heights of H1, H2, and H3 can be adjusted.

[0229] In some embodiments, along the direction from the water inlet hole 24 to the water outlet hole 26, the inclination angle of the bottom surface of the first section of the channel 40 with respect to the horizontal plane is smaller than the inclination angle of the bottom surface of the second section of the channel 42 with respect to the horizontal plane.

[0230] In this way, the second section of the channel 42 is more inclined, which is beneficial for the sewage to flow faster and wash away the dirt.

[0231] Specifically, combined with FIG. 21, the inclination angle a of the bottom surface of the first section of the channel 40 with respect to the horizontal plane is smaller than the inclination angle b of the bottom surface of the second section of the channel 42 with respect to the horizontal plane, a < b, which further makes the second section of the channel 42 more inclined, beneficial for the sewage to flow faster and wash away the dirt.

[0232] Optionally, a and b can be acute angles. Optionally, a can be an acute angle and b can be a right angle.

[0233] Please refer to FIG. 4. In some embodiments, the cleaning tank structure 100 includes a water outlet hole 26 and a filter member 54. The water outlet hole 26 is connected to the cleaning tank 10, and the filter member 54 is accommodated in the water outlet hole 26.

[0234] Thus, the filter element 54 can filter the sewage to avoid pipe blockage.

[0235] Specifically, in Figures 4 to 8, the water outlet 26 is provided on the bottom surface of the cleaning tank 10. A filter cavity 56 is provided within the filter element 54, and filter holes 58 are provided on the bottom and / or sidewalls of the filter cavity 56. Sewage can be filtered through the filter holes 58 and then flow out of the cleaning tank 10. Debris in the sewage can be retained in the filter element 54, thus preventing pipe blockage and facilitating the removal of debris.

[0236] In one embodiment, the sewage scraped by the mop 11 can flow into the filter chamber 56. At this time, the debris in the sewage can be blocked by the filter hole 58 and remain in the filter element 54. The filtered sewage can be discharged through the outlet hole 26, thereby filtering the sewage and avoiding pipe blockage.

[0237] Optionally, the filter element 54 is removably disposed within the water outlet 26. Debris accumulated within the filter element 54 can be removed for regular cleaning. After cleaning, the filter element 54 can be reinstalled within the water outlet 26. The number and shape of the filter holes 58 are not specifically limited. The number of filter holes 58 can be multiple, and the shape of the filter holes 58 can be not only circular but also other shapes. Optionally, the filter element 54 is also provided with a handle 60 to facilitate user installation and removal of the filter element 54.

[0238] 4 to 6 , using the left washing trough 10 as an example, while the mop 11 is washing in the washing trough 10, it rotates clockwise. The mop 11 is first moistened with clean water near the water inlet 24. Then, it is squeezed by the ridges 14, which push the scraped garbage and dirty water into the water supply channel 28, where it flows with the water to the water outlet 26. As the mop 11 continues to rotate, it continues to move to the bottom area of ​​the rear trough 34 and the front trough 30, scraping and cleaning the bottom area. Garbage flows into the water outlet 26 along with the water flow. At the same time, because the water outlet 26 is concave, the dirty water on the mop 11 flows into the water outlet 26 due to gravity.

[0239] It can be understood that the mop 11 in the right cleaning tank 10 rotates in a counterclockwise direction. For specific explanations, please refer to the above description.

[0240] Please refer to Figures 10 to 13, 16 and 17. In some embodiments, the cleaning tank structure 100 includes a drain pipe 62, which is connected to the cleaning tank 10 through the water outlet 26. A recess 64 is provided at the bottom of the filter element 54, and the recess 64 is correspondingly connected to the connecting hole 68 formed by the drain pipe 62 on the wall of the water outlet 26.

[0241] Thus, the recessed portion 64 at the bottom of the filter element 54 corresponds to the communicating hole 68 , making it easier for water to flow into the drain pipe 62 .

[0242] Specifically, because recess 64 is connected to communication hole 68, communication hole 68 can communicate with the space enclosed by recess 64. Filter element 54 does not block or only blocks communication hole 68. Sewage flowing from filter element 54 can more easily flow into communication hole 68 and out of cleaning tank structure 100 through drain pipe 62, thereby allowing sewage to be promptly discharged from cleaning tank 10. Filter holes 58 are provided on the sidewalls of recess 64. Corresponding to recess 64, a raised portion 66 is formed within filter chamber 56. Raised portion 66 protrudes from the sidewalls of filter chamber 56 and connects to the bottom of filter chamber 56. Raised portion 66 can block some larger waste.

[0243] Please refer to Figures 9 to 13. In some embodiments, the cleaning tank structure 100 includes a water outlet 26 and a drain pipe 62. The drain pipe 62 is connected to the cleaning tank 10 through the water outlet 26. A accommodating cavity 70 is provided at the bottom of the cleaning tank structure 100, and the drain pipe 62 is located in the accommodating cavity 70.

[0244] Therefore, the drain pipe 62 is located in the accommodating cavity 70 , and the drain pipe 62 is shorter, which can reduce the cost of the cleaning tank structure 100 .

[0245] Specifically, in one embodiment, the cleaning tank structure 100 can be manufactured using a mold. The drain pipe 62 is located within the accommodating cavity 70 and does not extend outside the accommodating cavity 70. The drain pipe 62 is relatively short. On the one hand, the shorter drain pipe 62 can be pushed out of the mold using a shorter push rod, making it easier to open the mold of the cleaning tank structure. On the other hand, the shorter drain pipe 62 can also reduce material usage, thereby reducing the cost of the cleaning tank structure 100. In summary, the cost of the cleaning tank structure 100 can be reduced.

[0246] Optionally, the drain pipe 62 has a water pipe interface 72 , which is located in the accommodating cavity 70 . The pipe can be inserted into the drain through the water pipe interface 72 to guide the water out of the cleaning tank structure 100 .

[0247] Please refer to Figures 2 and 4 to 7. In some embodiments, the cleaning tank structure 100 includes a first side wall 73 and a second side wall 75. The first side wall 73 and the second side wall 75 surround the cleaning tank 10. The cleaning tank structure 100 is provided with a water inlet 24 and an inlet 78. The water inlet 24 is connected to the cleaning tank 10. The first side wall 73 and the second side wall 75 are respectively connected to the two opposite edges of the water inlet 24. Compared with the second side wall 75, the first side wall 73 is closer to the inlet 78; the diameter N1 of the circle where the first side wall 73 is located is greater than the diameter N2 of the circle where the second side wall 75 is located, and the width E1 of the first side wall 73 along the horizontal direction is greater than the width E2 of the second side wall 75 along the horizontal direction.

[0248] This helps to overcome the offset error when the cleaning robot returns to the station.

[0249] Specifically, in Figure 4 , first sidewall 73 is the front sidewall, and second sidewall 75 is the rear sidewall. When the cleaning robot returns to the station, it must step over first sidewall 73 to enter cleaning tank 10. Along direction D, because first sidewall 73 is closer to entrance 78, its horizontal width E1 is greater. This helps cleaning tank structure 100 overcome offset errors when the cleaning robot returns to the station, making it easier for the cleaning robot to enter the station.

[0250] Please refer to Figure 8. In some embodiments, the cleaning tank structure 100 includes a first baffle 74 and a second baffle 76. The first baffle 74 and the second baffle 76 surround the cleaning tank 10. The first side wall 73 is the side wall of the first baffle 74 facing the cleaning tank 10, and the second side wall 75 is the side wall of the second baffle 76 facing the cleaning tank 10. The height D2 of the second baffle 76 is greater than the height D1 of the first baffle 74.

[0251] Thus, on the one hand, it is easier for the cleaning robot to enter the station, and on the other hand, the higher second baffle 76 can also prevent or reduce sewage from splashing out of the cleaning tank 10.

[0252] Specifically, the first bar 74 is the front bar, and the second bar 76 is the rear bar. The first bar 74 is closer to the entrance 78, and the cleaning robot needs to step over it to enter the cleaning tank 10. The first bar 74 has a smaller height D1, so it is positioned lower, reducing resistance when the cleaning robot returns to the station and making it easier for the cleaning robot to enter. The second bar 76 is further away from the entrance 78, allowing the mop 11 to be placed in the cleaning tank 10 after the cleaning robot returns. The higher second bar 76 prevents or reduces the amount of wastewater in the cleaning tank 10 from spilling outside the tank, thus reducing the extra cleaning burden on the user.

[0253] The diameter of the circle in which the first baffle 74 is located is greater than the diameter of the circle in which the second baffle 76 is located. When the mop 11 is located in the portion of the cleaning groove 10 surrounded by the second baffle 76, the edge of the mop 11 is closer to the second baffle 76, and the second baffle 76 exerts a greater amount of pressure on the mop 11, which can better clean the mop 11.

[0254] In FIG8 , the first stop bar 74 and the second stop bar 76 are both arc-shaped to form a substantially circular cleaning tank 10, which can be adapted to accommodate the rotating mop 11. It is understood that the present application does not impose any specific limitation on the shapes of the cleaning tank 10 and the mop 11.

[0255] Optionally, the first stop bar 74 and the second stop bar 76 can both be soft stop bars 22. Optionally, the first stop bar 74 can be soft stop bars 22, and the second stop bar 76 can be hard stop bars 22. Optionally, the first stop bar 74 and the second stop bar 76 can both be hard stop bars 22. Optionally, the soft stop bars 22 can be made of rubber (such as TPU) or silicone. Optionally, the hard stop bars 22 can be made of plastic (such as ABS or PC).

[0256] Optionally, referring to FIG. 10 , the cleaning tank 10 may be formed by a first recess 130 provided on the top surface of the base 20 , and the first side wall 73 and the second side wall 75 may be side walls of the first recess 130 .

[0257] In some embodiments, the junction between the second side wall 75 and the edge of the water inlet hole 24 is closer to the center of the washing tank 10 than the junction between the first side wall 73 and the edge of the water inlet hole 24. Along the rotation direction of the mop 11, the junction between the second side wall 75 and the edge of the water inlet hole 24 is located behind the junction between the first side wall 73 and the edge of the water inlet hole 24.

[0258] Thereby, the cleaning effect of the mop 11 can be improved.

[0259] Specifically, the connection between the second side wall 75 and the edge of the water inlet hole 24 is hereinafter referred to as the second connection 80 , and the connection between the first side wall 73 and the edge of the water inlet hole 24 is hereinafter referred to as the first connection 82 .

[0260] Referring to Figure 4 , the mop 11 located in the left side of the cleaning tank 10 rotates in a clockwise direction R1 during cleaning. Along the clockwise direction R1, the second connection 80 is located behind the first connection 82. During cleaning, the mop 11 on the left side rotates in the clockwise direction R1, moving from the portion of the cleaning tank 10 enclosed by the first sidewall 73 to the portion of the cleaning tank 10 enclosed by the second sidewall 75. The fluff 12 of the mop 11 strikes the second connection 80, which is closer to the center of the cleaning tank 10. This knocks dirty water and debris off the mop 11 and allows it to fall into the cleaning tank 10.

[0261] The mop 11 in the right washing tank 10 rotates counterclockwise R2 during cleaning. In this counterclockwise direction R2, the second connection 80 is located behind the first connection 82. During cleaning, the right mop 11 rotates counterclockwise R2, moving from the portion of the washing tank 10 enclosed by the first sidewall 73 to the portion of the washing tank 10 enclosed by the second sidewall 75. The fluff 12 of the mop 11 strikes the second connection 80, which is closer to the center of the washing tank 10. This knocks dirty water and debris off the mop 11 and allows it to fall into the washing tank 10.

[0262] In summary, the cleaning effects of the two mops 11 can be improved.

[0263] Furthermore, the junction between the second sidewall 75 and the edge of the water inlet hole 24 is closer to the center of the cleaning tank 10 than the junction between the first sidewall 73 and the edge of the water inlet hole 24. Along the rotational direction of the mop 11, the junction between the second sidewall 75 and the edge of the water inlet hole 24 is located behind the junction between the first sidewall 73 and the edge of the water inlet hole 24. This can better squeeze the mop 11 and scrape off the garbage on the mop 11. In particular, large particles of garbage can be collected in the water outlet 26 through the central water supply channel 28. Optionally, since the edges of the mop 11 are likely to be dirty, a corresponding squeezing member can be provided at the edges of the mop 11 to enhance the cleaning effect.

[0264] Please refer to Figures 11 to 13. In some embodiments, the cleaning tank structure 100 includes a first baffle 74, which encloses a portion of the cleaning tank 10. The cleaning tank structure 100 is provided with a water inlet 24 and an entrance 78. The water inlet 24 is connected to the cleaning tank 10. The first baffle 74 includes a first part 88 and a second part 90. The first part 88 connects the edge of the water inlet 24 and the second part 90. The second part 90 is arranged close to the entrance 78. Compared with the bottom surface of the cleaning tank 10, the height F2 of the second part 90 is less than the height F1 of the first part 88.

[0265] Thus, the height F1 of the first portion 88 is higher, which can prevent the mop 11 from splashing water out from the edge of the water inlet 24, and the height F2 of the second portion 90 is lower, which can reduce the resistance of the cleaning robot entering the station.

[0266] Specifically, the first bar 74 can be arc-shaped and can enclose a portion of the cleaning tank 10, forming a sidewall of the cleaning tank 10. The first bar 74 can be located near the front side of the base 20. In one embodiment, when the mop 11 is cleaning in the cleaning tank 10, the mop 11 can rotate to cause water at the edge of the water inlet 24 to be spun. The first portion 88 is connected to the edge of the water inlet 24. The height F1 of the first portion 88 is relatively high, thereby preventing the mop 11 from splashing water out of the edge of the water inlet 24.

[0267] The second part 90 can be set at a position close to the entrance 78, and the double turntable mop of the cleaning robot can enter the cleaning tank 10 from the entrance 78. The height F2 of the second part 90 is relatively low, which can facilitate the double turntable mop of the cleaning robot to enter the cleaning tank 10.

[0268] Optionally, the first baffle 74 is a soft baffle 22 (for example, made of silicone), so that the first baffle 74 has good softness, is easy to deform and can recover deformation, thereby avoiding excessive return resistance to the cleaning robot and protecting the mop 11 of the cleaning robot.

[0269] Please refer to Figures 7 and 11 to 13. In some embodiments, the cleaning tank structure 100 includes a second baffle 76, which surrounds another part of the cleaning tank 10. The first part 88 and the second baffle 76 are respectively connected to the two opposite edges of the water inlet 24. Compared with the bottom surface of the cleaning tank 10, the height D2 of the second baffle 76 is not less than the height F1 of the first part 88. The second baffle 76 is provided with a detection hole 92. The cleaning tank structure 100 includes a water level detection device 94, which is connected to the cleaning tank 10 through the detection hole 92.

[0270] In this way, the height D2 of the second baffle 76 is not less than the height F1 of the first portion 88, which can further prevent the mop 11 from splashing water out of the edge of the water inlet 24. At the same time, by providing a water level detection device 94, the water level in the cleaning tank 10 can be monitored to prevent water from overflowing from the cleaning tank 10.

[0271] Specifically, the second bar 76 can be arc-shaped. The second bar 76 can enclose another portion of the cleaning tank 10 and serve as another sidewall of the cleaning tank 10. The second bar 76 can be positioned near the rear side of the base 20. In one embodiment, when the mop 11 is cleaning in the cleaning tank 10, the mop 11 can rotate to cause water at the edge of the water inlet 24 to swirl. The first portion 88 and the second bar 76 can respectively connect the two opposite edges of the water inlet. The height D2 of the second bar 76 can be substantially equal to the height F1 of the first portion 88, thereby further preventing the mop 11 from splashing water out of the edge of the water inlet 24.

[0272] The second bar 76 may have a detection hole 92 at one end away from the water inlet 24, which is connected to the washing tank 10. When the mop 11 is located in the washing tank 10 and clean water is flowing into the water inlet 24, the mop 11 can rotate within the washing tank 10, thereby moving water to various areas of the washing tank 10. When the water outflow from the water outlet 26 is less than the water inflow from the water inlet 24, the water level within the washing tank 10 will rise. A water level detection device 94 may be installed on one side of the second bar 76 and connected to the washing tank 10 through the detection hole 92. This device can monitor the water level within the washing tank 10 and prevent water from overflowing.

[0273] 4 , in some embodiments, the cleaning tank structure 100 includes a third bar 96 , which connects the first bar 74 and the second bar 76 , and the third bar 96 is surrounded by a water inlet 24 .

[0274] Specifically, in FIG4 , the third bar 96 may be shaped like a U. One end of the third bar 96 may be connected to the first portion 88, and the other end may be connected to the second bar 76. The bottom end of the third bar 96 is connected to the base 20. The third bar 96 is surrounded by a water inlet 24, so that clean water can flow from the water inlet 24 into the water supply channel 28.

[0275] It should be noted that the end surface of the first portion 88 away from the bottom surface 101 of the cleaning tank 10 (i.e., the top surface 128 of the first portion 88), the end surface of the second baffle 76 away from the bottom surface 101 of the cleaning tank 10 (i.e., the top surface 128 of the second baffle 76), and the end surface of the third baffle 96 away from the bottom surface 101 of the cleaning tank 10 (i.e., the top surface 128 of the third baffle 96) are located in the same first horizontal plane.

[0276] 4 , in some embodiments, the cleaning tank structure 100 is provided with an air inlet 102 , the second blocking bar 76 is provided with a second notch 98 , and the air inlet 102 is connected to the cleaning tank 10 through the second notch 98 .

[0277] In this way, wind can enter the cleaning tank 10 and dry the mop 11 after cleaning.

[0278] Specifically, the air inlet 102 can be positioned near the rear side of the base 20. In Figure 4 , the second retaining bar 76 can be provided with a second notch 98 near the air inlet 102. A fan (not shown) can blow hot air into the cleaning tank structure 100 through the air inlet 102. Since the second notch 98 is connected to the air inlet 102, after the mop 11 is cleaned, the hot air can be blown toward the mop 11 while the mop 11 continues to rotate, thereby drying the mop 11.

[0279] Please refer to Figures 28 to 30. In some embodiments, the bottom surface of the cleaning tank 10 includes a spiral surface 104, the spiral surface 104 includes a starting end 106 and an ending end 108 arranged along the spiral direction of the spiral surface 104, and the ridge 14 connects the starting end 106; the cleaning tank structure 100 includes a drainage structure 110, and the drainage structure 110 is connected to the ending end 108; the cleaning tank structure 100 is configured so that when the mop 11 is placed on the ridge 14, the spiral surface 104 contacts the mop 11, and the spiral direction of the spiral surface 104 is consistent with the movement direction of the mop 11.

[0280] In this way, while the ridges 14 are scraping the mop 11, the mop 11 can contact the spiral surface 104. In the process of cleaning the mop 11, the mop 11 can clean the spiral surface 104 from the starting end 106 to the ending end 108, and then discharge the debris into the drainage structure 110, thereby avoiding or reducing the debris from remaining on the spiral surface 104, thereby avoiding or reducing the chance of the cleaning tank structure 100 stinking.

[0281] Specifically, in FIG28 , the bottom surface of the cleaning tank 10 includes a spiral surface 104. Along the spiral direction Y of the spiral surface 104, the spiral surface 104 may have two ends: a starting end 106 and a terminal end 108. Along the H direction, the spiral surface 104 may spirally extend from the upper portion of the cleaning tank 10 to the lower portion of the cleaning tank 10, such that the starting end 106 is near the upper portion of the cleaning tank 10, the terminal end 108 is near the lower portion of the cleaning tank 10, and the starting end 106 is located above the terminal end 108. The ridge 14 may be connected to the starting end 106. The drainage structure 110 may be connected to the terminal end 108.

[0282] In one embodiment, when the mop 11 of the cleaning robot needs to be cleaned, the mop 11 can be placed on the ridges 14. The cleaning robot can rotate the mop 11, causing the ridges 14 to scrape and clean the mop 11. While the ridges 14 are scraping and cleaning the mop 11, the mop 11 can come into contact with the spiral surface 104. During the cleaning process, the mop 11 can clean the spiral surface 104 from the starting end 106 to the ending end 108, thereby draining debris into the drainage structure 110, preventing or reducing debris from remaining on the spiral surface 104. This can prevent or reduce the chance of the cleaning tank structure 100 from odor.

[0283] In Figure 28 , the water outlet 26 can be rectangular in shape. The water outlet 26 can be located on the bottom surface of the drainage structure 110, near the rear side of the washing tank 10. The drainage structure 110 is provided with a drainage channel 112, which is located below the water supply channel 28 along the H direction. The water supply channel 28 connects to the drainage channel 112, which in turn connects to the water outlet 26.

[0284] In one embodiment, the sewage and other debris after cleaning the mop 11 can flow into the drainage channel 112 through the water supply channel 28. The drainage channel 112 is connected to the water outlet 26, so that the sewage flowing into the drainage structure 110 can flow away through the water outlet 26, avoiding the sewage from being blocked in the drainage channel 112.

[0285] Furthermore, the drainage channel 112 may be inclined from an end away from the water outlet 26 toward an end close to the water outlet 26 , so that wastewater and other debris flowing into the drainage channel 112 can flow faster toward the water outlet 26 .

[0286] 28 , the bottom surface of the cleaning trough 10 includes an inclined surface 114. Along the thickness direction Z of the ridges 14, the inclined surface 114 and the spiral surface 104 can be provided on opposite sides of the two ridges 14. The spiral surface 104 and the inclined surface 114 can be provided on opposite sides of the water supply channel 28, respectively. The inclined surface 114 can be connected to a side surface of the cleaning trough 10 on the rear side. In one embodiment, during the rotational cleaning process of the mop 11, the mop 11 can scrape and clean with a ridge 14 near the inclined surface 114, and the scraped debris can fall onto the inclined surface 114. By tilting the inclined surface 114 downward from the side of the cleaning trough 10 toward the drainage structure 110, when the debris cleaned by the mop 11 falls on the inclined surface 114, it can be easily discharged into the drainage structure 110.

[0287] Please refer to Figure 30. In some embodiments, a plurality of protrusions 14 are provided in the cleaning tank 10. The plurality of protrusions 14 and the bottom surface of the cleaning tank 10 form a water supply channel 28. The cleaning tank structure 100 includes a protrusion 116. The protrusion 116 is protruded from the bottom surface of the cleaning tank 10. The protrusion 116 includes a blocking surface 118 facing the water supply channel 28. The blocking surface 118 is spaced opposite to the opening of the water supply channel 28.

[0288] Specifically, in FIG30 , the protrusion 116 can be cylindrical in shape. It can be protruded from the spiral surface 104 along the axis P of the spiral surface 104. The side of the protrusion 116 facing the water supply channel 28 can form a blocking surface 118. The blocking surface 118 is spaced apart from the opening of the water supply channel 28. The lower end of the blocking surface 118 can be connected to the drainage channel 112. The opening of the water supply channel 28 can be connected to the top of the drainage structure 110. In one embodiment, during the cleaning process of the mop 11 in the cleaning tank 10, the cleaned sewage can be discharged through the opening of the water supply channel 28. Since the water supply channel 28 is inclined from the water inlet 24 to the direction of the drainage structure 110, the flow rate of the sewage flowing out of the opening of the water supply channel 28 is relatively large, and there is no obstruction on the opposite side, so the sewage can flow to the spiral surface 104. However, by setting the blocking surface 118, the sewage flowing out of the opening of the water supply channel 28 can be blocked, thereby preventing the sewage from falling on the spiral surface 104 again, avoiding secondary pollution.

[0289] Furthermore, the other side of the protrusion 116 can form a guide surface 120, which can be connected to the spiral surface 104. Sewage and other debris falling on the spiral surface 104 can be guided to flow into the drainage structure 110 through the guide surface 120 to prevent debris from accumulating on the spiral surface 104. The guide surface 120 can be an arc-shaped surface.

[0290] In some embodiments, the cleaning tank structure 100 includes a nano-layer (not shown), which is disposed on at least one of the bottom surface of the cleaning tank 10 and the circumferential side surface of the cleaning tank 10 .

[0291] In this way, the hydrophobic and oleophobic properties of the nano-layer can be utilized to reduce the amount of dirt attached to the bottom surface of the cleaning tank 10 and the circumferential side surfaces of the cleaning tank 10 .

[0292] Specifically, in one embodiment, the nanolayer can be provided on the bottom surface of the cleaning tank 10. In one embodiment, the nanolayer can be provided on the circumferential side surface of the cleaning tank 10, that is, the side surface of the first and second baffles 74, 76 close to the cleaning tank 10. In one embodiment, the nanolayer can be provided on the bottom surface of the cleaning tank 10 and the circumferential side surface of the cleaning tank 10.

[0293] The nanolayer has hydrophobic and oleophobic properties. The nanolayer is disposed on the bottom surface of the cleaning tank 10 or the circumferential side surfaces of the cleaning tank 10, significantly reducing the amount of dirt adhering to the cleaning tank 10, slowing down the odor of the sewage, making the cleaning tank 10 easier to clean, and significantly improving the user experience. The thickness and material of the nanolayer are not specifically limited. Optionally, the nanolayer may include an ultra-thin self-healing hydrophobic coating, the thickness of which may be less than 100 nm (nanometers).

[0294] The nanolayer significantly improves the cleanliness of the cleaning tank 10, offering acid, alkali, and corrosion resistance comparable to the surface properties of the cleaning tank 10's raw materials. Furthermore, the nanolayer coating process is generally cheaper than that of a super-hydrophobic coating, helping to reduce costs. The nanolayer effectively improves the cleanliness of the cleaning tank 10, preventing dirt from adhering to it and bacteria from growing, making it easier to clean and improving the user experience.

[0295] 10 , in some embodiments, the cleaning tank structure 100 includes a base 20 , a first recess 130 is formed on a top surface 128 of the base 20 , and the first recess 130 constitutes the cleaning tank 10 .

[0296] In this way, the cleaning tank 10 can be formed in the base 20 through the first recess 130 , thereby reducing the use of other materials.

[0297] Specifically, the top surface 128 may be recessed downward to form a first recess 130. The first recess 130 may be circular, so that the cleaning tank 10 may be formed on the base 20 through the first recess 130, reducing the use of other materials. Optionally, the first recess 130 may be manufactured through an integrated molding process.

[0298] 10 , in some embodiments, a second recess 132 is formed on the top surface 128 of the base 20 . The second recess 132 constitutes a water inlet 24 , and the water inlet 24 is connected to the cleaning tank 10 .

[0299] In this way, the water inlet 24 can be formed in the base 20 through the second recess 132 , further reducing the use of other materials.

[0300] Specifically, the base 20 can be recessed downward to form a second recess 132, which forms a water inlet 24. The water inlet 24 is connected to the washing tank 10. Thus, the water inlet 24 can be formed in the base 20 through the second recess 132, reducing the use of other materials. Optionally, the water inlet 24 can be in the form of a groove, and the second recess 132 can be manufactured through an integrated molding process.

[0301] Please refer to Figure 5. In some embodiments, the ridge 14 includes a first side surface 17, which faces the side wall of the cleaning tank 10 and is connected to the bottom surface of the cleaning tank 10. The minimum distance from the top of the ridge 14 to the bottom surface 101 of the cleaning tank 10 is greater than or equal to 2 mm.

[0302] In this way, the contact area between the mop 11 and the first side surface 17 of the convex strip 14 can be ensured to be larger, thereby improving the scraping effect of the convex strip 14 on the mop 11.

[0303] Specifically, in Figures 5 and 7, the cleaning tank 10 is substantially circular, and the first side surface 17 of the protrusion 14 faces the circumferential side surface of the cleaning tank 10. The first side surface 17 connects the top of the protrusion 14 and the bottom surface 101 of the cleaning tank 10. The first side surface 17 of the protrusion 14 may be the transition area from the top of the protrusion 14 to the bottom surface 101 of the cleaning tank 10. The minimum distance Q between the first side surface 17 of the protrusion 14 and the bottom surface 101 of the cleaning tank 10 along the top of the protrusion 14 is greater than or equal to 2 mm. For example, the minimum distance Q between the first side surface 17 of the protrusion 14 and the bottom surface 101 of the cleaning tank 10 along the top of the protrusion 14 may be 2.2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, or other values ​​greater than 2 mm. The upper limit of the minimum distance Q between the first side surface 17 of the protrusion 14 and the bottom surface 101 of the cleaning tank 10 along the top of the protrusion 14 can be determined according to actual needs and is not specifically limited in this application. Optionally, along the direction from the water inlet 24 to the water outlet 26, the top of the ridge 14 is not in the same horizontal plane, and the top of the ridge 14 has multiple connecting sections with successively decreasing slopes. Therefore, the distance from the first side surface 17 of the ridge 14 along the top of the ridge 14 to the bottom surface 101 of the cleaning tank 10 may be multiple. In this embodiment, the average distance of the multiple connecting sections to the bottom surface 101 of the cleaning tank 10 can be used for limitation.

[0304] The minimum distance Q between the first side surface 17 of the ridge 14 and the bottom surface 101 of the cleaning tank 10 along the top of the ridge 14 is greater than or equal to 2 mm. This can reduce the inclination angle of the first side surface 17 of the ridge 14 and allow the top of the ridge 14 to transition more smoothly to the bottom surface 101 of the cleaning tank 10. This can increase the contact area between the mop 11 and the first side surface 17 of the ridge 14, thereby improving the scraping effect of the ridge 14 on the rotating mop 11.

[0305] Optionally, the ridge 14 further includes a second side surface 19, and the second side surface 19 of the ridge 14 is connected to the bottom surface of the water supply channel 28. The second side surfaces 19 of the two ridges 14 can form the water supply channel 28 with the bottom surface 101 of the cleaning tank 10.

[0306] In certain embodiments, as shown in FIG36 , the cleaning tank structure 100 further includes a water outlet 26 and a nozzle. The cleaning tank 10 is connected to the water outlet, and the nozzle is disposed above the cleaning tank 10. The nozzle is configured to spray water toward the cleaning tank 10 and / or the water outlet 26. By discharging water from the nozzle to clean the water outlet 26, it is possible to avoid accumulation of stains in the water outlet 26 and prevent the cleaning tank 10 from being blocked from draining. At the same time, cleaning is simple and convenient, and the cleaning tank 10 can be prevented from stinking. The nozzle is rotatably disposed above the cleaning tank 10, so that the nozzle has a wider cleaning range for the cleaning tank 10 and the water outlet 26. The rotation angle of the nozzle ranges from [0°, 60°]. In this way, the cleaning range is wider, and the water sprayed from the nozzle 25 can be prevented from flowing out of the cleaning tank 10. The rotation angle of the nozzle 25 can be 0°, 5°, 10°, 20°, 30°, 35°, 40°, 45°, 50°, or 60°, or any other value within the range of [0°, 60°]. In some embodiments, the nozzle 25 has a nozzle 25a that is fan-shaped. This allows the water sprayed by the nozzle 25 to form a larger spray area, thereby extending the cleaning range.

[0307] As shown in Figure 37, the top of the protrusion 14 includes a first section 141, a second section 142 and a third section 143 connected in sequence along the direction from the water inlet hole 24 to the water outlet hole 26. Relative to the bottom surface of the cleaning tank 10, the height of the first section 141 is greater than the height of the third section 143.

[0308] Therefore, the first section 141 near the water inlet 24 is higher, the contact area between the mop 11 and the ridge 14 is larger, and the clean water entering from the water inlet 24 can more easily wash away the stains on the mop 11. The third section 143 is lower, the contact area between the mop 11 and the ridge 14 is smaller, and the dirty water is not easily stained on the mop 11.

[0309] The cleaning tank structure 100 includes a first baffle 74 and a bottom plate 1001. The first baffle 74 and the bottom plate 1001 together enclose at least a portion of the cleaning tank 10. At least a portion of the first baffle 74 is movably connected to the bottom plate 1001. The cleaning tank 10 has an inlet and outlet 102. At least a portion of the first baffle 74 can move between a first position and a second position. In the first position, at least a portion of the first baffle 74 closes the inlet and outlet 102 (as shown in Figure 38). In the second position, at least a portion of the first baffle 74 opens the inlet and outlet 102 (as shown in Figure 39).

[0310] In the above-mentioned cleaning tank structure 100, at least a portion of the first baffle 74 can be movably connected to the bottom plate 14. At least a portion of the first baffle 74 in the second position opens the inlet and outlet 102 of the cleaning tank 10, thereby facilitating the cleaning robot to enter and exit the cleaning tank 10 through the inlet and outlet 102. At least a portion of the first baffle 74 in the first position closes the inlet and outlet 102 of the cleaning tank 10, facilitating the cleaning robot to clean the mop 11 and other operations.

[0311] In some embodiments, the ribs 14 are rotatably positioned within the cleaning tank 10. The cleaning tank structure 100 is configured such that, when the mop 11 is not rotating, the ribs 14 rotate to cause relative movement between the ribs 14 and the mop 11, thereby cleaning the mop 11. Thus, when the mop 11 is not rotating, the ribs 14 rotate to cause relative movement between the ribs 14 and the mop 11, thereby cleaning the mop 11.

[0312] In certain embodiments, the cleaning tank structure 100 is configured such that, when the mop 11 rotates, the ridges 14 rotate in the same direction as the mop 11, but at a different speed than the mop 11, causing the ridges 14 and the mop 11 to move relative to each other, thereby cleaning the mop 11 and the bottom surface 101 of the cleaning tank 10. Thus, while the ridges 14 rotate in the same direction as the mop 11, the ridges 14 rotate at a different speed than the mop 11, thereby causing relative movement between the ridges 14 and the mop 11.

[0313] In some embodiments, the cleaning tank structure 100 is configured so that when the mop 11 rotates, the ridges 14 rotate in the opposite direction of the mop 11, causing the ridges 14 and the mop 11 to move relative to each other to clean the mop 11 and the bottom surface 101 of the cleaning tank 10. This allows for a higher relative rotational speed between the ridges 14 and the mop 11, resulting in a better cleaning effect of the ridges 14 on the mop 11.

[0314] In some embodiments, the cleaning tank structure 100 is configured so that when the mop 11 rotates, the ridges 14 do not rotate, allowing the ridges 14 and the mop to move relative to each other to clean the mop 11 and the bottom surface 101 of the cleaning tank 10. In this way, the mop 11 and the bottom surface 101 of the cleaning tank 10 can be cleaned simultaneously by simply rotating the mop 11.

[0315] Specifically, the cleaning tank structure 100 may include a driving member 15 and a transmission member (not shown). The driving member may include a motor 152, and the driving member 15 is connected to a driving shaft 151 through a transmission member. The motor 152 can be installed on the back of the cleaning tank 10, that is, the side opposite to the contact surface of the cleaning tank 10 and the mop 11. The driving shaft 151 is connected to the motor 152, passes through the top of the side wall of the water supply channel 28, and is connected to the ridge 14. The motor 152 provides power to the driving shaft 151, and the driving shaft 151 drives the ridge 14 to rotate, so that the ridge 14 and the mop 11 in contact therewith can produce relative motion, thereby achieving the purpose of cleaning the mop 11. The transmission member connects the driving member 15 and the ridge 14, and the transmission member includes but is not limited to a belt, a reduction gear set, a rack, a screw, etc.

[0316] In certain embodiments, the cleaning tank structure 100 includes a water inlet 24 and a water outlet 26. The cleaning tank 10 includes multiple cleaning tanks, with at least two cleaning tanks 10 connected to a common water inlet 24. Each cleaning tank is connected to a water outlet 26. The water inlet 24 is connected to the water outlet 26 through the cleaning tank 10, and the bottom surface 101 of the cleaning tank 10 is inclined from the water inlet 24 toward the water outlet 26. In this application, water is concentrated inflow from at least two cleaning tanks through a single water inlet 24, making it easier to connect the water inlet 24 to an external water source. Water is then diverted through the respective water outlets 26 of the cleaning tanks 10. This improves the efficiency of water inflow and outflow within the cleaning tank 10 and prevents excessive accumulation of solid impurities in a single water outlet 26, which could cause the cleaning tank 10 to stink.

[0317] In some embodiments, the cleaning tank structure 100 includes a cleaning tank 10, a drainage channel 112, and a movable filter element 54. The drainage channel 112 has an installation opening 1120 formed on the top surface of the cleaning tank structure 100. The drainage channel 112 includes a filter section 1121 and a flow channel section 1122 that are interconnected.

[0318] The filter element 54 includes a filter portion 24 and a flow channel portion 26 connected to each other. The filter element 54 can be switched between a first position and a second position via an installation port 1120. In the first position, the filter portion 24 is located in the filter section 1121, and the flow channel portion 26 is located in the flow channel section 1122. The flow channel section 1122 communicates with the cleaning tank 10 through the filter portion 24. In the second position, the filter portion 24 is located outside the filter section 1121, and the flow channel portion 26 is located outside the flow channel section 1122.

[0319] In the above-mentioned cleaning tank structure 100, when the filter element 54 is in the first position, the water in the cleaning tank 10 can flow into the flow channel section 1122 through the filter portion 24, and then the water in the cleaning tank 10 can be filtered. When the filter element 54 is in the second position, the filter portion 24 is located outside the filter section 1121, and the flow channel portion 26 is located outside the flow channel section 1122, so that the user can conveniently clean the drainage channel 112 through the installation port 1120, avoiding the problem of stains remaining in the drainage channel 112 and causing the cleaning tank structure 100 to stink.

[0320] As shown in FIG42 , in some embodiments, a cleaning tank structure 100 includes a cleaning tank 10 and a cleaning member. The cleaning member is located within the cleaning tank 10 and includes a scraping portion and a combing portion 23. The scraping portion and the combing portion 23 are protruding from the bottom surface of the cleaning tank 10. The scraping portion in this application can be a convex strip 14, and the combing portion 23 is provided on one side of the convex strip 14 along its own length to form the cleaning member.

[0321] The cleaning tank structure 10 is configured such that when a mop is placed in the cleaning tank 10 , the mop 11 directly contacts the scraping portion and the combing portion 23 , so that the combing portion 23 combs the mop 11 and the scraping portion scrapes the mop 11 .

[0322] In the aforementioned cleaning tank structure 100, when the mop 11 is cleaning in the cleaning tank 10, the mop 11 directly contacts the scraping and combing sections 23. The combing section 23 combs the mop 11, and the scraping section scrapes the mop 11, thereby making the cleaning tank structure 10 more thorough and efficient in cleaning the mop 11. In one embodiment, the combing section 18 includes a plurality of protrusions, the average height of which is less than or equal to the height of the opposing scraping section.

[0323] The cleaning tank structure 100 includes a cleaning tank 10 and a ridge 14. The ridge 14 is protruding from the bottom surface 101 of the cleaning tank 10. As shown in FIG43 , the ridge includes a first section 141 and a second section 142. Compared to the bottom surface 101 of the cleaning tank 10, the height of the second section 142 is greater than that of the first section 141.

[0324] The cleaning tank structure 100 is configured such that when the mop 11 is placed in the cleaning tank 10 , the mop 11 contacts the first section 141 , the second section 142 and the contact area 16 .

[0325] In the above-mentioned cleaning tank structure 10, the second section 142 is used to clean the mop 11, and the first section 141 can reduce the lifting height of the mop 11, thereby reducing the gap between the mop 11 and the bottom surface 101 of the cleaning tank 10 to a certain extent, thereby enabling the mop 11 to have a good cleaning effect on the bottom surface 102 of the cleaning tank 10 (such as the contact area 16) and reducing the accumulation of stains on the bottom surface 101 of the cleaning tank 10.

A cleaning robot can use the climbing plate 126 to place a mop 11 into the cleaning tank 10. It will be appreciated that the cleaning tank structure 100 can be installed not only in the base station 200 but also in other equipment for cleaning components of other equipment.

[0331] In the embodiment shown in FIG4 , the cleaning tank structure 100 can be used in conjunction with a dual-rotating disc cleaning robot. After cleaning, the cleaning robot returns to the base station 200 and places the mop 11 in the cleaning tank 10 for cleaning. The base station 200 also charges the cleaning robot and collects dust. After the mop 11 is cleaned or the robot is fully charged, the cleaning robot can leave the base station 200 to continue cleaning, or remain at the base station 200 until the next cleaning instruction is received.

[0332] Optionally, the base station 200 and the cleaning tank structure 100 can be integrated, and there is no need to remove the cleaning tank structure 100 for cleaning. Optionally, the cleaning tank structure 100 can also be detachably installed on the base station 200, and the cleaning tank structure 100 can be used as a detachable part, and the user can take it out for cleaning.
