[0003] In related art, the base station is usually used with the sweeping robot. The sweeping robot can return to the base station for mop cleaning, charging and other operations. After long-term use of the base station, the water tank of the base station will be smelly due to the debris of the mop falling into the water tank. SUMMARY

[0004] The utility model embodiment provides a kind of cleaning tank structure and cleaning equipment to solve at least one technical problem existing above.

[0005] The cleaning tank structure of the utility model embodiment comprises:

[0006] The barrier strip encloses the cleaning tank, and the bottom surface of the cleaning tank comprises at least one of a contact area and a non-contact area;

[0007] The convex strip is located in the cleaning tank;

[0008] The cleaning tank structure is configured to:

[0009] When the mop is placed on the convex strip, the contact area directly contacts the mop in rotation and non-rotation, and the non-contact area has a vertical distance between the plane where the mop is located in rotation and non-rotation.

[0010] In some embodiments, the cleaning tank structure is provided with an entrance, and the height of the barrier strip near the entrance is less than the height of the barrier strip away from the entrance along the H direction.

[0011] In some embodiments, the cleaning tank structure is also provided with a second gap, and the second gap is located on the side of the barrier strip away from the entrance along the rotation direction of the mop and is connected to the cleaning tank. The height of the barrier strip near the second gap is greater than the height of the barrier strip near the entrance along the H direction.

[0012] In some embodiments, the barrier strip comprises a first barrier strip and a second barrier strip, and the first barrier strip and the second barrier strip enclose the cleaning tank. The height of the second barrier strip is greater than the height of the first barrier strip along the H direction.

[0013] In some embodiments, the convex strips are connected to the cleaning tank as an integral structure.

[0014] In some embodiments, the cleaning tank structure includes a base, the blocking bar forms two interconnected cleaning tanks on the base, the water outlet is located at the connecting point of the two cleaning tanks, and the base is connected to the cleaning tank and the convex bar to form an integrated structure.

[0015] In some embodiments, the baffle is provided with a detection hole, the cleaning tank structure includes a water level detection device, and the water level detection device is connected to the cleaning tank through the detection hole.

[0016] In some embodiments, the cleaning tank structure is configured so that when the mop is placed in the cleaning tank, the range of the amount of compression between the edge of the mop and the side wall of the cleaning tank is (0, 10] mm.

[0017] In some embodiments, the cleaning tank structure is configured such that when the mop is placed in the cleaning tank, there is a horizontal distance between the edge of the mop and the blocking bar.

[0018] In some embodiments, the horizontal distance between the edge of the mop and the barrier strip is in the range of (0,8] mm; and / or,

[0019] The range of the amount of extrusion between the mop and the bottom surface of the cleaning tank is [0, T) mm, where T is the thickness of the mop.

[0065] Please refer to Figures 1 to 6 The cleaning tank structure 100 of the present embodiment includes a cleaning tank 10 and a convex strip 14. The bottom surface 101 of the cleaning tank 10 includes a contact area 16. The convex strip 14 is located in the cleaning tank 10. The cleaning tank structure 100 is configured such that the contact area 16 is in direct contact with the mop 11 when the mop 11 is placed on the convex strip 14, whether the mop 11 is rotating or not.

[0066] In the cleaning tank structure 100 described above, the contact area 16 can be in direct contact with the mop 11 when the mop 11 is placed on the convex strip 14, whether the mop 11 is rotating or not. Therefore, during the cleaning of the mop 11, the rotating mop 11 can clean the contact area 16, which can avoid or reduce the debris remaining on the bottom surface 101 of the cleaning tank 10, thereby avoiding or reducing the probability of the cleaning tank structure 100 emitting odor.

[0067] Specifically, the cleaning robot includes a body and a mop 11, and the mop 11 can be installed at the bottom of the body. In the present embodiment, the rotational axis of the mop 11 is substantially perpendicular to the bottom of the body when the mop 11 is rotating. It can be understood that the rotational axis of the mop 11 is substantially perpendicular to the ground when the cleaning robot is standing and working normally. When the cleaning robot is in the station, the lowest point of the mop 11 is located at the position of the cleaning tank 10 close to the front of the base station 200, and the highest point of the mop 11 is located at the position of the cleaning tank 10 close to the rear side of the base station 200.

[0068] In Figure 4In some embodiments, the cleaning tank 10 is adapted to a circular mop 11, so that the mop 11 can be cleaned in the cleaning tank 10. The cleaning tank 10 adapted to a triangular mop 11. It is understood that in some embodiments, the cleaning tank 10 is adapted to a triangular, quadrilateral or polygonal mop 11, so that the mop 11 can be cleaned in the cleaning tank 10. In some embodiments, the cleaning tank 10 is irregularly shaped, but is adapted to the mop 11, so that the mop 11 can be cleaned in the cleaning tank 10.

[0069] In some embodiments, the cleaning tank structure 100 is adapted to a cleaning robot with a single mop 11, and the single mop 11 can rotate in the cleaning tank 10 in the clockwise direction R1 or the counterclockwise direction R2. The present application is not limited in this regard.

[0070] In some embodiments, the cleaning tank structure 100 is adapted to a cleaning robot with two mops 11. The two mops 11 placed in the two cleaning tanks 10 can rotate in the same direction or different directions, for example, in combination with Figure 6 In some embodiments, 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 some embodiments, 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. The present application is not limited in this regard. The length direction L includes the left-right direction.

[0071] When the mop 11 of the cleaning robot needs to be cleaned, the cleaning robot can enter the base station 200, the mop 11 can be placed on the convex strip 14, and the cleaning robot can drive the mop 11 to rotate, so that the convex strip 14 moves relative to the mop 11, and the convex strip 14 scrapes the mop 11.

[0072] In some embodiments, when the mop 11 is placed on the convex strip 14, the rotating mop 11 can directly contact the contact area 16 while the convex strip 14 scrapes the mop 11. In this way, the rotating mop 11 can clean the contact area 16 during the cleaning of the mop 11, which can avoid or reduce the dirt remaining on the bottom surface 101 of the cleaning tank 10, and thus can avoid or reduce the odor of the cleaning tank structure 100.

[0073] In some embodiments, the cleaning tank structure 100 is adapted to a cleaning robot with a single mop 11, and the single mop 11 can rotate in the cleaning tank 10 in the clockwise direction R1 or the counterclockwise direction R2. The present application is not limited in this regard. Figure 1In some embodiments, along the vertical direction H of the cleaning tank structure 100, the vertical direction H of the cleaning tank structure 100 includes a height direction and a vertical direction. Alternatively, in one embodiment, the entire cleaning tank 10 bottom surface 101 can be the contact area 16, that is, the entire cleaning tank 10 bottom surface 101 is in direct contact with the rotating and non-rotating mop 11.

[0074] Alternatively, please refer to Figure 4 The convex strip 14 extends along the radial direction of the cleaning tank 10, so that the length of the convex strip 14 is longer, the contact area of the mop 11 is larger, and the scrubbing effect on the mop 11 is improved.

[0075] Alternatively, the convex strip 14 is connected to the cleaning tank 10 as an integral structure, so that the cleaning tank structure 100 has low cost and high rigidity. For example, the cleaning tank structure 100 can be integrally manufactured by injection molding process, so that the convex strip 14 is connected to the cleaning tank 10 as an integral structure.

[0076] The illustrated cleaning tank structure 100 is provided with two cleaning tanks 10, which can be adapted to a cleaning robot with double-disc cleaning elements, and the bottom of each disc cleaning element can be provided with a mop 11. The rotation of the disc cleaning element can drive the mop 11 to rotate, and the rotation axis of the mop 11 is substantially perpendicular to the bottom of the machine body. During cleaning, the rotation directions of the two mops 11 can be the same or opposite, which is not specifically limited by the present application. During the cleaning process of the cleaning robot, the rotation directions of the two mops 11 can be the same or opposite. It can be 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 a cleaning robot with a single-disc cleaning element.

[0077] Alternatively, in Figure 1 In some embodiments, the mop 11 can be provided with an opening near the center of the mop 11. Alternatively, in other embodiments, the mop 11 can also not be provided with an opening near the center of the mop 11.

[0078] Please refer to Figure 1 and Figure 2 In some embodiments, the cleaning tank 10 bottom surface 101 includes a non-contact area 18, and the cleaning tank structure 100 is configured as:

[0079] When the mop 11 is placed on the convex strip 14, the vertical distance between the non-contact area 18 and the plane where the mop 11 is located ranges from (0, 3] mm.

[0080] In this way, in the process of cleaning the mop 11, when the mop 11 is placed on the convex strip 14, the mop 11 can drive the water flow to the non-contact area 18 when rotating to clean the non-contact area 18, and at the same time, the non-contact area 18 can increase the friction between the mop 11 and the bottom surface 101 of the cleaning tank 10, reduce the energy consumption, and adapt to a low-power motor.

[0081] Specifically, in one embodiment, the bottom surface 101 of the cleaning tank 10 further comprises a non-contact area 18 when the mop 11 is placed on the convex strip 14. 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 is in the range of (0, 3] mm, and the mop 11 can drive the water flow to the non-contact area 18 when rotating to clean the non-contact area 18 in the process of cleaning the mop. 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 where 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 according to actual needs, and the utility model does not make specific limitations on this.

[0082] Optionally, in Figure 3 In the embodiment shown, the mop 11 comprises the fluff 12 and the bottom disc 13, the fluff 12 is arranged at the bottom of the bottom disc 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.

[0083] Optionally, in Figure 23 In the embodiment shown, the contact area 16 can be a slope, and the non-contact area 18 can also be a slope, and the slope of the non-contact area 18 is greater than the slope of the contact area 16. In Figure 24 In the embodiment shown, the contact area 16 can be a horizontal plane, and the non-contact area 18 can also be a horizontal plane. In Figure 25 In the embodiment shown, the contact area 16 can be a horizontal plane, and the non-contact area 18 can be a slope. In Figure 26 In the embodiment shown, the contact area 16 can be a slope, and the non-contact area 18 can be a horizontal plane. In Figure 27 In the embodiment shown, the contact area 16 can be a slope, and the non-contact area 18 can also be a slope, and the slope of the non-contact area 18 is equal to the slope of the contact area 16. The contact area 16 can be a curved surface or an arc surface, and the non-contact area 18 can also be a curved surface or an arc surface.

[0084] Please refer to Figure 33As can be seen from the effect diagram, 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 is not in contact with the bottom surface 101 of the cleaning tank 10, the rotating mop 11 can have the desired cleaning effect on the non-contact area 18, reducing the probability of odor of the cleaning tank structure 100.

[0085] Specifically, in Figure 33 , y represents the vertical extrusion amount of the mop 11 and the bottom surface 101 of the cleaning tank 10, and the unit is mm. When y < 0, it means that the mop 11 and the bottom surface 101 of the cleaning tank 10 are isolated, and at this time, the absolute value of y represents the isolation amount (i.e., the vertical distance W). F represents the cleaning effect after the cleaning robot self-cleans once. Each test spreads 5g of yellow mud on the ground, and the cleaning robot cleans after returning once. After self-cleaning, the weight z (unit: g) of the dirt added to the cleaning tank 10 is weighed, and F = 1 - z / 5 x 100%. When self-cleaning once, F >= 90% cleaning effect meets the cleaning requirement.

[0086] From Figure 33 , it can be seen that when y >= -3 (i.e., the vertical distance W is in the range of (0, 3] mm), the cleaning effect F >= 90%, which meets the cleaning requirement. When -3 <= y < 0, the mop 11 will drive the water in the cleaning tank 10 to flow when rotating, thereby washing the cleaning tank 10 through the water flow, so as to achieve the effect of cleaning the cleaning tank 10. When y > 0, the mop 11 is extruded with the bottom surface 101 of the cleaning tank 10, and the friction between the mop 11 and the bottom surface 101 of the cleaning tank 10 makes the cleaning effect meet the requirement. Based on the fact that the mop 11 is composed of the chassis 13 and the fluff 12, the chassis 13 belongs to hard material and is difficult to extrude, so the vertical extrusion amount of the mop 11 and the bottom surface 101 of the cleaning tank 10 cannot be taken as the thickness of the mop 11. The test data is shown in Table 1 below. The smaller z is, the less yellow mud is left in the cleaning tank 10, and the better the cleaning effect on the cleaning tank 10.

[0087] Table 1

[0088]

[0089] Please refer to Figure 4 , Figure 10 , Figure 20 and Figure 31 , in some embodiments, the cleaning tank structure 100 comprises a base 20, and the cleaning tank 10 is arranged in the base 20.

[0090] In this way, the base 20 can provide a mounting structure of the cleaning tank structure 100, facilitating the installation of the cleaning tank structure 100.

[0091] As Figure 8As shown, the cleaning tank structure 100 includes a base 20, a baffle 22 on the base 20 to form two interconnected cleaning tanks 10, and a water outlet 26 is located at the connection point of the two adjacent cleaning tanks 10, that is, the two interconnected cleaning tanks 10 share one water outlet 26. Specifically, Figure 4 In the illustrated embodiment, 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 sidewalls 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. Each cleaning tank 10 is provided with two raised strips 14, which are symmetrically arranged. Optionally, the base 20 may be connected to the cleaning tank 10 and the raised strips 14 to form an integral structure.

[0092] Please combine Figure 1 a and Figure 22 In some embodiments, the structure 100 of the cleaning tank 10 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.

[0093] 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.

[0094] 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.

[0095] exist Figure 1 a In the example, the left cleaning tank 10 is used for illustration. Since the circular area T0 is a circular area formed with the center O of the bottom surface 101 of the cleaning tank 10 and a preset radius, and 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 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 preset radius of the circular area T0 is smaller than the radius of the cleaning tank 10.

[0096] Optionally, in Figure 1 aIn the embodiment, 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.

[0097] The preset radius can be specifically limited according to needs, and the present invention does not make any specific limitations on this.

[0098] 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;

[0099] 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.

[0100] 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.

[0101] 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 .

[0102] 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 .

[0103] Optionally, in Figure 1 a In the embodiment, two ridges 14 are provided in the cleaning tank 10, and the two 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. Figure 1 a In the embodiment, 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.

[0104] 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.

[0105] The first bottom surface area 101a is a part of the first conical bottom surface, and the second bottom surface area 101b is a part of the second conical bottom surface. Figure 1 a, the radius of the circle where the first bottom surface area 101a is located is greater than the radius of the circle where the second bottom surface area 101b is located. Optionally, the radius of the circle where the first bottom surface area 101a is located is less than or equal to the radius of the circle where the second bottom surface area 101b is located.

[0106] 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.

[0107] 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.

[0108] Optionally, in Figure 1 a In the example, the first preset radius is equal to the second preset radius, and the center of the first circular area T1 coincides with the center of the second circular area T2 ( Figure 1 a It is understood 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 and the center of the second circular area T2 may not coincide.

[0109] 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.

[0110] Please combine Figures 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.

[0111] 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.

[0112] 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.

[0113] In some examples, the amount of compression between the mop 11 and the bottom surface 101 of the washing tank 10 may 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 are not specifically limited in the present invention. 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.

[0114] Please combine Figure 1 and Figure 2 In some embodiments, the cleaning tank structure 100 is configured so that when the mop 11 is placed in the cleaning tank 10, there is a horizontal distance between the edge of the mop 11 and the side wall of the cleaning tank 10. The horizontal distance between the edge of the mop 11 and the side wall of the cleaning tank 10 is the horizontal distance between the edge of the mop 11 and the baffle 22, and the range of the horizontal distance between the edge of the mop 11 and the baffle 22 is (0,8] mm.

[0115] 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.

[0116] Specifically, when the mop 11 is placed in the cleaning tank 10 and rotates on the ridges 14 for cleaning, the edge of the mop 11 can contact a portion of the side wall of the cleaning tank 10 (such as Figure 2 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 according to actual needs and is not specifically limited in the present invention.

[0117] 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.

[0118] Please combine Figure 34 As can be seen from the effect diagram, 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 when 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.

[0119] Specifically, in Figure 34 Here, x represents the horizontal distance between the edge of the mop 11 and the sidewall of the trough 10 (or, if a barrier 22 is provided, the side of the barrier 22 facing the trough 10), measured in mm. When x < 0, the edge of the mop 11 is isolated from the sidewall of the trough 10. The absolute value of x represents the distance, or horizontal distance U. F represents the cleaning performance of the robot after a single self-cleaning operation. During each test, 5g of mud was sprinkled on the ground. After the robot returned to its station and performed a self-cleaning operation, the weight of dirt added to the trough 10 (z, in grams) was measured. F = 1 - z / 5 × 100%. After a single self-cleaning operation, F > = 90% of the cleaning performance met the cleaning requirements.

[0120] In this test, the y value is fixed, such as setting y = 1mm. Figure 34 As can be seen, when -8 <= x <= 10, the cleaning effect F >= 90%, meeting the cleaning requirements. When x < -8, the distance between the sidewalls of the cleaning tank 10 and the edge of the mop 11 is too far. The rotating mop 11, relying on the water flow and the fluff 12, cannot clean the sidewalls of the cleaning tank 10, resulting in a blind spot and poor cleaning performance. When x > 10, the mop 11 is excessively squeezed against the sidewalls of the cleaning tank 10, causing it to bulge, partially separating from the bottom surface 101 of the cleaning tank 10. This significant separation affects cleaning performance. The test data is shown in Table 2 below.

[0121] Table 2 (y = 1 mm (1 / 6.5 of the mop thickness))

[0122] x z F -10 1 80％ -8 0.5 90％ -4 0 100％ 0 0 100％ 4 0 100％ 8 0.2 96％ 10 0.48 90.4％ 12 1.2 76％

[0123] Please combine Figure 2In some embodiments, the cleaning tank structure 100 is configured so that when the mop 11 is placed in the cleaning tank 10, 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.

[0124] 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.

[0125] Specifically, when the mop 11 is placed in the cleaning tank 10 and rotates on the ridges 14 for cleaning, the edge of the mop 11 can contact a portion of the side wall of the cleaning tank 10 (such as Figure 2 Optionally, the amount of 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. For example, the amount of extrusion 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 extrusion 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 the present invention.

[0126] 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.

[0127] 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.

[0128] Please combine Figure 35 , because the squeezing amount of the mop 11 in the vertical direction is more important to the cleaning effect, when the squeezing amount of the mop 11 in the vertical direction is relatively large (close to the critical value, y = 6.0mm, the squeezing amount is equal to the thickness of the mop 11 6.0 / 6.5), when the mop 11 meets the cleaning requirements, in the horizontal direction x range, and explore whether the y value has an impact on the x range that meets the cleaning requirements.

[0129] from Figure 35It can be seen that when y = 6.0 mm, -8 < = x < = 10, the cleaning effect F > = 90%, which meets the cleaning requirements. At the same time, compared with Table 1, it is found that the value of y has no obvious effect on the range of x that meets the cleaning requirements. Because the value of y mainly affects the cleaning effect in the vertical direction, when the value of y meets the cleaning requirements, it will not have obvious effect on the effective value of x. The test data is shown in Table 3.

[0130] Table 3 (y = 6.0 mm) (mop thickness 6.0 / 6.5)

[0131] x z F -10 1 80％ -8 0.4 92％ -4 0 100％ 0 0 100％ 4 0 100％ 8 0.1 98％ 10 0.45 91％

[0132] Optionally, when the mop 11 reaches the maximum extrusion amount with the side wall of the cleaning tank 10, and the mop 11 reaches the maximum extrusion amount with the bottom surface 101 of the cleaning tank 10, the mop 11 can still rotate (i.e. the motor of the cleaning robot can still drive the mop 11 to rotate), and will not cause the motor to run overload, and will not affect the cleaning of the rotation of the mop 11.

[0133] It should be pointed out that the test data is the thickness of the mop 11 in the above test, which is 6.5 mm, and the data is obtained by averaging the test data.

[0134] In some embodiments, the cleaning tank structure 100 includes a blocking strip 22, and the blocking strip 22 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 blocking strip 22.

[0135] In this way, the cleaning tank 10 can be surrounded by the blocking strip 22, and the structure is simple.

[0136] Specifically, the cleaning tank structure 100 can be provided with a plurality of blocking strips 22, and the plurality of blocking strips 22 can surround the cleaning tank 10, so that when the mop 11 is placed in the cleaning tank 10 for cleaning, the blocking strip 22 can block the water in the cleaning tank 10, preventing the water from flowing to other areas outside the cleaning tank 10.

[0137] Optionally, the blocking strip 22 can be hard rubber (such as ABS, PC, etc.), or soft rubber (such as TPU, silicone, etc.).

[0138] Optionally, please refer to Figure 10 The cleaning tank 10 can be formed by a first recess 130 provided on the top surface of the base 20, and the side wall of the cleaning tank 10 can be the side wall of the first recess 130.

[0139] Please refer to Figure 4 and Figure 5In some embodiments, the cleaning tank structure 100 includes a water inlet hole 24 and a water outlet hole 26, and the cleaning tank 10 is provided with a plurality of protrusions 14, which form a water delivery channel 28 with the bottom surface of the cleaning tank 10, and the water delivery channel 28 is connected to the water inlet hole 24 and the water outlet hole 26.

[0140] In this way, the water inlet hole 24 can deliver clean water through the water delivery channel 28, and the dirty water after cleaning can be discharged from the water outlet hole 26 through the water delivery channel 28.

[0141] Specifically, in some embodiments, along the width direction D of the cleaning tank structure 100, the water inlet hole 24 can be arranged near one side of the width and near the rear side of the base 20. The water outlet hole 26 can be arranged near the front side of the base 20 in the D direction. The width direction includes the front-rear direction. Compared with the water delivery channel 28, the water inlet hole 24 is located at a higher position, and the water outlet hole 26 is located at a lower position. The water entering from the water inlet hole 24 can flow to the water outlet hole 26 through the water delivery channel 28 under the action of gravity. Figure 4 In some embodiments, along the width direction D of the cleaning tank structure 100, the water inlet hole 24 can be arranged near one side of the width and near the rear side of the base 20. The water outlet hole 26 can be arranged near the front side of the base 20 in the D direction. The width direction includes the front-rear direction. Compared with the water delivery channel 28, the water inlet hole 24 is located at a higher position, and the water outlet hole 26 is located at a lower position. The water entering from the water inlet hole 24 can flow to the water outlet hole 26 through the water delivery channel 28 under the action of gravity.

[0142] Figure 4 In some embodiments, the two protrusions 14 form the water delivery channel 28 with the bottom surface of the cleaning tank 10. In one embodiment, the mop 11 can rotate on the protrusions 14, and in the process of rotation, the mop 11 can be soaked with clean water in the water delivery channel 28, and the soaked mop 11 can be scrubbed by the protrusions 14. The dirty water or dirt after scrubbing can flow into the water outlet hole 26 through the water delivery channel 28, so that the dirty water can be discharged through the water outlet hole 26. It can be understood that in other embodiments, the water delivery channel 28 can be formed by three, four or other number of protrusions 14 with the bottom surface of the cleaning tank 10, which is not specifically limited here.

[0143] Further, in some embodiments, along the D direction, the water delivery channel 28 can separate the cleaning tank 10 into a front tank 30 and a rear tank 34. The front tank 30 is arranged near the front side of the base 20, and the rear tank 34 is arranged 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 can form a first opening 32. The bottom surface of the front tank 30 can be connected to the top of the water outlet hole 26. The protrusions 14 near the front tank 30 can scrub the mop 11, and the dirty water or dirt after scrubbing can fall into the front tank 30 and finally flow into the water outlet hole 26 through the first opening 32. The bottom surface of the rear tank 34 can be connected to the top of the water outlet hole 26. The protrusions 14 near the rear tank 34 can scrub the mop 11, and the dirty water or dirt after scrubbing can fall into the rear tank 34 and finally flow into the water outlet hole 26. Figure 4 Please refer to

[0144] and Figure 19 and Figure 20 ​In some embodiments, at least one of the two protrusions 14 surrounding the water delivery channel 28 is provided with a first gap 36, which is in communication with the water delivery channel 28 and the cleaning tank 10.

[0145] In this way, the dirt and the like in the cleaning tank 10 can flow into the water delivery channel 28 through the first gap 36 and then be discharged through the water outlet hole 26.

[0146] Specifically, in some embodiments, the two protrusions 14 are symmetrically arranged in the cleaning tank 10, and a first gap 36 is arranged at the middle of each protrusion 14. Figure 19 In this way, the dirt and the like in the cleaning tank 10 can flow into the water delivery channel 28 through the first gap 36 and then be discharged through the water outlet hole 26.

[0147] Specifically, in some embodiments, the two protrusions 14 are symmetrically arranged in the cleaning tank 10, and a first gap 36 is arranged at the middle of each protrusion 14. Figure 19 In this way, the dirt and the like in the cleaning tank 10 can flow into the water delivery channel 28 through the first gap 36 and then be discharged through the water outlet hole 26.

[0148] In this way, the dirt and the like in the cleaning tank 10 can flow into the water delivery channel 28 through the first gap 36 and then be discharged through the water outlet hole 26.

[0149] Specifically, in some embodiments, the two protrusions 14 are symmetrically arranged in the cleaning tank 10, and a first gap 36 is arranged at the middle of each protrusion 14.

[0150] In this way, the dirt and the like in the cleaning tank 10 can flow into the water delivery channel 28 through the first gap 36 and then be discharged through the water outlet hole 26.

[0151] In some embodiments, the protrusions 14 are inclinedly arranged towards the water delivery channel 28.

[0152] In this way, the angle between the protrusions 14 and the bottom surface of the cleaning tank 10 outside the water delivery channel 28 can be larger, so that the dirt and the like are less likely to be left at the angle.

[0153] Specifically, in some embodiments, the two protrusions 14 are symmetrically arranged in the cleaning tank 10, and a first gap 36 is arranged at the middle of each protrusion 14.Figure 4 In some embodiments, the two protrusions 14 can be inclinedly arranged towards the water delivery channel 28, and the included angle θ formed between the protrusions 14 and the bottom surface of the cleaning tank 10 can be obtuse. When the mop 11 is cleaned in the cleaning tank 10, the cleaned debris can be left at the included angle formed between the protrusions 14 and the bottom surface of the cleaning tank 10. By incliningly arranging the two protrusions 14 towards the water delivery channel 28, the included angle formed between the protrusions 14 and the bottom surface of the cleaning tank 10 outside the water delivery channel 28 can be larger, so as to avoid the debris left at the included angle due to the smaller included angle.

[0154] Please refer to Figures 14 to 16 In some embodiments, the water delivery channel 28 comprises a first section channel 40 and a second section channel 42, which are sequentially connected in the direction from the water inlet hole 24 to the water outlet hole 26, and the depth of the second section channel 42 is greater than or equal to the depth of the first section channel 40 compared with the water inlet hole 24.

[0155] In this way, the depth of the second section channel 42 is deeper, so as to avoid the secondary pollution of the mop 11 in the second section channel 42.

[0156] Specifically, the water delivery channel 28 comprises a connecting section channel 44, which is inclinedly arranged between the first section channel 40 and the second section channel 42. The first section channel 40, the connecting section channel 44 and the second section channel 42 are sequentially connected in the direction from the water inlet hole 24 to the water outlet hole 26. In the direction from the water inlet hole 24 to the water outlet hole 26, the depth of the connecting section channel 44 can be greater than or equal to the depth of the first section channel 40, and the depth of the second section channel 42 can be greater than or equal to the depth of the connecting section channel 44.

[0157] Optionally, in an embodiment, the connecting section channel 44 can be omitted, and the first section channel 40 can be directly communicated with the second section channel 42, as shown in Figure 16 .

[0158] In an embodiment, when the mop 11 rotates to enable the protrusions 14 to scrape and clean the mop 11, the pile 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 pile 12 of the mop 11. The cleaned sewage can flow to the second section channel 42 through the connecting section channel 44, and the depth of the second section channel 42 is deeper, so that the mop 11 or the pile 12 of the mop 11 cannot contact the sewage in the second section channel 42, thereby avoiding the secondary pollution of the mop 11 in the second section channel 42.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] Please combine Figures 14 to 16In some embodiments, the first section 40 includes a first end 46 and a second end 48, the second section 42 includes a third end 50 and a fourth end 52, the first end 46 is in communication with the water inlet hole 24, the second end 48 is in communication with the third end 50, and the fourth end 52 is in communication with the water outlet hole 26. The depth H1 of the first end 46 is in the range of [1, 5] mm, the depth H2 of the second end 48 and the third end 50 is in the range of [2, 8] mm, and the depth H3 of the fourth end 52 is in the range of [5, 15] mm, and H1 <= H2 <= H3.

[0166] In this way, by determining the depth range of each end of the first section 40 and the second section 42, it is further ensured that the mop 11 is not easily in contact with the sewage in the channel.

[0167] Specifically, in one embodiment, the first end 46 is in communication with the water inlet hole 24, the second end 48 is in communication with the third end 50, and the fourth end 52 is in communication with the water outlet hole 26, so that water can be discharged into the water outlet hole 26. Further, by setting the depth H1 of the first end 46 in the range of [1, 5] mm, the depth H2 of the second end 48 and the third end 50 in the range of [2, 8] mm, and the depth H3 of the fourth end 52 in the range of [5, 15] mm, such that H1 <= H2 <= H3, it is further ensured that the mop 11 is not easily in contact with the sewage in the channel.

[0168] The depth H1 of the first end 46 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or other values between 1 mm and 5 mm.

[0169] The depth H2 of the second end 48 and the third end 50 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or other values between 2 mm and 8 mm.

[0170] 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.

[0171] In combination Figure 16 , the depth H1 of the first end 46 to the depth H2 of the second end 48 of the mop 11 needs to ensure that the mop 11 can be in contact with the water in the water delivery channel 28, and the mop 11 cannot completely block the water delivery channel 28, and the depth H3 of the fourth end 52 of the mop 11 needs to ensure that it is not in contact with the sewage in the water delivery channel 28. The values of H1, H2 and H3 are related to the height L1 of the convex strip 14, the extrusion 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 of the water flow in the water delivery channel 28.

[0172] The gap L0 between the mop 11 and the top of the water delivery channel 28 is H1-L1-y; for H1=L1+y+L0, to satisfy that the mop 11 can wet the water at H1 and not block the water delivery channel 28, 0L0M, i.e. H3>L1+y+M, and H1H2H3. When L1=1, y=2, M=3 (unit: millimeter), 3H1<6, 3H2<6; H3>6. The height of H1, H2, H3 can be adjusted according to the parameters of L1, y, M.

[0173] In some embodiments, the angle of inclination of the bottom surface of the first section 40 relative to the horizontal plane is less than the angle of inclination of the bottom surface of the second section 42 relative to the horizontal plane in the direction from the water inlet hole 24 to the water outlet hole 26.

[0174] In this way, the second section 42 is more inclined, which is conducive to the faster flow of sewage and the flushing away of dirt.

[0175] Specifically, in combination with Figure 21 , the angle of inclination a of the bottom surface of the first section 40 relative to the horizontal plane is less than the angle of inclination b of the bottom surface of the second section 42 relative to the horizontal plane, a

[0176] Optionally, a and b can take acute angles. Optionally, a can take an acute angle and b can take a right angle.

[0177] Please refer to Figure 4 , in some embodiments, the cleaning tank structure 100 includes the water outlet hole 26 and the filter 54, the water outlet hole 26 is communicated with the cleaning tank 10, and the filter 54 is accommodated in the water outlet hole 26.

[0178] In this way, the filter 54 can filter the sewage, avoiding pipe blockage.

[0179] Specifically, in Figures 4 to 8 , the water outlet hole 26 is arranged on the bottom surface 101 of the cleaning tank 10. The filter cavity 56 is arranged in the filter 54, and the filter cavity 56 is provided with a filter hole 58 on the bottom and / or the side wall. The sewage can flow out of the cleaning tank 10 after being filtered through the filter hole 58, and the sundries in the sewage can be left in the filter 54, avoiding pipe blockage, and also facilitating the cleaning of the sundries.

[0180] In one embodiment, the sewage after being scraped and washed by the mop 11 can flow into the filter cavity 56, at which time the sundries in the sewage can be blocked by the filter hole 58 and left in the filter 54, and the filtered sewage can be discharged through the water outlet hole 26, thereby filtering the sewage and avoiding pipe blockage.

[0181] 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.

[0182] Combine Figures 4 to 6 Taking 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. From there, the scraped garbage and dirty water flow along 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 front trough 30, scraping and cleaning the bottom area. The garbage flows into the water outlet 26 along with the water. 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.

[0183] 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.

[0184] Please combine Figures 10 to 13 、 Figure 16 and Figure 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 connected to a connecting hole 68 formed by the drain pipe 62 on the wall of the water outlet 26.

[0185] 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 .

[0186] Specifically, because recess 64 is in corresponding communication with communication hole 68, communication hole 68 can communicate with the space enclosed by recess 64. Filter element 54 does not block or only minimally blocks communication hole 68, allowing sewage flowing from filter element 54 to 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. A convex bump 66 is formed within filter cavity 56 corresponding to recess 64.

[0187] Please combine Figures 9 to 13In some embodiments, the cleaning tank structure 100 comprises a water outlet hole 26 and a drain pipe 62, the drain pipe 62 is connected to the cleaning tank 10 through the water outlet hole 26, and the cleaning tank structure 100 is provided with a receiving cavity 70 at the bottom, and the drain pipe 62 is located in the receiving cavity 70.

[0188] In this way, the drain pipe 62 is located in the receiving cavity 70, and the drain pipe 62 is short, which can reduce the cost of the cleaning tank structure 100.

[0189] Specifically, in one embodiment, the cleaning tank structure 100 can be manufactured by a mold. The drain pipe 62 is located in the receiving cavity 70, and the drain pipe 62 does not protrude out of the receiving cavity 70, the drain pipe 62 is short, on the one hand, the shorter drain pipe 62 can use a shorter push rod to push the drain pipe 62 out of the mold, so that the cleaning tank structure is easier to open the mold, on the other hand, the shorter drain pipe 62 can also reduce the use of materials, so that the cost of the cleaning tank structure 100 is reduced. In summary, the cost of the cleaning tank structure 100 can be reduced.

[0190] Optionally, the drain pipe 62 has a water pipe interface 72, the water pipe interface 72 is located in the receiving cavity 70, and the pipe can be sleeved into the drain pipe through the water pipe interface 72 to guide the water flow out of the cleaning tank structure 100.

[0191] Please refer to Figure 2 , Figures 4 to 7 In some embodiments, the cleaning tank structure 100 comprises 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 hole 24 and an entrance 78, the water inlet hole 24 is connected to the cleaning tank 10, the first side wall 73 and the second side wall 75 are respectively connected to the edges opposite to each other of the water inlet hole 24, and the first side wall 73 is closer to the entrance 78 than the second side wall 75; 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 in the horizontal direction is greater than the width E2 of the second side wall 75 in the horizontal direction.

[0192] In this way, it is beneficial to overcome the deviation error when the cleaning robot returns to the station.

[0193] Specifically, in Figure 4 , the first side wall 73 is a front side wall, and the second side wall 75 is a rear side wall. When the cleaning robot returns to the station, it needs to cross the first side wall 73 and enter the cleaning tank 10. In the D direction, since the first side wall 73 is closer to the entrance 78, and the width E1 of the first side wall 73 in the horizontal direction is greater, it is beneficial for the cleaning tank structure 100 to overcome the deviation error when the cleaning robot returns to the station, so that the cleaning robot is easier to enter the station.

[0194] Please refer to Figure 8In some embodiments, the cleaning tank structure 100 is provided with an entrance 78. Along the H direction, the height of the barrier bar 22 on the side closer to the entrance 78 is lower than the height on the side farther from the entrance 78. Thus, when the mop 11 enters the cleaning tank 10 from the entrance 78 for cleaning, the higher side of the barrier bar 22, farther from the entrance 78, can prevent or reduce the spillage of wastewater from the cleaning tank 10 outside the cleaning tank 10, thereby avoiding an additional cleaning burden on the user. The barrier bar 22 includes a first side wall 73 and a second side wall 75. The cleaning tank structure is provided with an entrance 78. Compared to the second side wall 75, the first side wall 73 is closer to the entrance 78. Along the H direction, the height of the second side wall 75 is higher than the height of the first side wall 73. Thus, on the one hand, the lower first side wall 73 makes it easier for the cleaning robot to enter the station, and on the other hand, the higher second side wall 75 can also prevent or reduce wastewater from splashing out of the cleaning tank 10.

[0195] In some embodiments, the cleaning trough structure further includes a second notch 98. This second notch 98 is located on the side of the barrier bar 22 away from the entrance 78 along the rotation direction of the mop 11 and communicates with the cleaning trough 10. Along the H direction, the height of the barrier bar 22 near the second notch 98 is greater than the height of the barrier bar 22 near the entrance 98. This prevents the mop 11 from splashing water when it rotates to the second notch 98. The mop 11 can rotate clockwise and / or counterclockwise. If the cleaning trough structure 100 is provided with two cleaning troughs 10, the mop 11 placed in the left cleaning trough 10 can rotate in the clockwise direction R1, while the mop 11 placed in the right cleaning trough 10 can rotate in the counterclockwise direction R2.

[0196] When the baffle 22 in this embodiment includes the first baffle 74 and the 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. Along the H direction, the height D2 of the second baffle 76 is greater than the height D1 of the first baffle 74.

[0197] 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.

[0198] 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.

[0199] exist Figure 8 In the embodiment, 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 invention does not specifically limit the shapes of the cleaning tank 10 and the mop 11.

[0200] 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).

[0201] Optionally, see Figure 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 .

[0202] 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.

[0203] Thereby, the cleaning effect of the mop 11 can be improved.

[0204] 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 .

[0205] Please combine Figure 4The mop 11 in the left cleaning trough 10 rotates in a clockwise direction R1 during cleaning. The second connection 80 is located behind the first connection 82 along the clockwise direction R1. When the mop 11 on the left side rotates in the clockwise direction R1, it moves from the portion of the cleaning trough 10 enclosed by the first sidewall 73 to the portion of the cleaning trough 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 trough 10. This knocks dirty water and debris off the mop 11 and allows it to fall into the cleaning trough 10.

[0206] 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.

[0207] In summary, the cleaning effects of the two mops 11 can be improved.

[0208] 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.

[0209] exist Figure 4 In the embodiment, the height of the baffle 22 on the opposite sides of the ridge 14 along its width direction is higher than the height of the baffle 22 on the side close to the station entrance 78. When the baffle 22 includes the first baffle 74 and the second baffle 76, as described above, the first baffle 74 is the front baffle and the second baffle 76 is the rear baffle, and the first baffle 74 is closer to the station entrance 78. The first baffle 74 includes a first portion 88 and a second portion 90. The first portion 88 is located on the side of the ridge 14 along its width direction close to the station entrance 78, and the second portion 90 is located close to the station entrance 78. Compared with the bottom surface of the cleaning tank 10, as shown in FIG. Figure 12As shown, the height F2 of the second portion 90 is less than the height F1 of the first portion 88. The ridge 14 extends along its width direction away from the second stop bar 76 on the other side of the station entrance 78. The height D2 of the second stop bar 76 is not less than the height F1 of the first portion 88 and is greater than the height F2 of the second portion 90.

[0210] Please combine 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 inlet 78. The water inlet 24 is connected to the cleaning tank 10. The first baffle 74 includes a first portion 88 and a second portion 90. The first portion 88 connects the edge of the water inlet 24 and the second portion 90. The second portion 90 is arranged close to the inlet 78. Compared with the bottom surface of the cleaning tank 10, the height F2 of the second portion 90 is less than the height F1 of the first portion 88.

[0211] 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.

[0212] 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.

[0213] The second part 90 can be set at a position close to the entrance 78, and the double turntable cleaning part 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 cleaning part of the cleaning robot to enter the cleaning tank 10.

[0214] 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.

[0215] Please combine Figure 7 、 Figures 11 to 13In some embodiments, the blocking strip 22 is provided with a detection hole 92, and the cleaning tank structure 100 is provided with a water level detection device 94, which is connected to the cleaning tank 10 through the detection hole 92 to monitor the water level in the cleaning tank 10 and prevent water from overflowing from the cleaning tank 10. Specifically, the cleaning tank structure 100 includes a second blocking strip 76, which encloses another part of the cleaning tank 10. The first part 88 and the second blocking strip 76 are respectively connected to the opposite edges of the water inlet hole 24. The height D2 of the second blocking strip 76 is not less than the height F1 of the first part 88 compared with the bottom surface of the cleaning tank 10. The second blocking strip 76 is provided with a detection hole 92, and the cleaning tank structure 100 is provided with a water level detection device 94, which is connected to the cleaning tank 10 through the detection hole 92.

[0216] In this way, the height D2 of the second blocking strip 76 is not less than the height F1 of the first part 88, which can further prevent the mop 11 from splashing water from the edges of the water inlet hole 24. In addition, the water level detection device 94 can be arranged to monitor the water level in the cleaning tank 10 and prevent water from overflowing from the cleaning tank 10.

[0217] Specifically, the second blocking strip 76 can have a circular arc shape. The second blocking strip 76 can enclose another part of the cleaning tank 10 and serve as another side wall of the cleaning tank 10. The second blocking strip 76 can be arranged close to the rear side of the base 20. In one embodiment, when the mop 11 is being cleaned in the cleaning tank 10, the mop 11 can rotate to drive the water at the edges of the water inlet hole 24 to splash. The first part 88 and the second blocking strip 76 can be respectively connected to the opposite edges of the water hole. The height D2 of the second blocking strip 76 can be substantially equal to the height F1 of the first part 88, which can further prevent the mop 11 from splashing water from the edges of the water inlet hole 24.

[0218] The second blocking strip 76 can be provided with a detection hole 92 at the end away from the water inlet hole 24, and the detection hole 92 can be connected to the cleaning tank 10. In the case that the mop 11 is located in the cleaning tank 10 and the water inlet hole 24 is connected to clean water, the mop 11 can rotate in the cleaning tank 10 to drive the water to various areas of the cleaning tank 10. When the water outlet amount of the water outlet hole 26 is less than the water inlet amount of the water inlet hole 24, the water level in the cleaning tank 10 will rise. The water level detection device 94 can be installed on one side of the second blocking strip 76, and the water level detection device 94 can be connected to the cleaning tank 10 through the detection hole 92 to monitor the water level in the cleaning tank 10 and prevent water from overflowing from the cleaning tank 10.

[0219] Please refer to Figure 4 In some embodiments, the cleaning tank structure 100 includes a third blocking strip 96, which is connected to the first blocking strip 74 and the second blocking strip 76, and encloses the water inlet hole 24.

[0220] Specifically, in Figure 4In the embodiment, 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.

[0221] 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.

[0222] Please combine Figure 4 In some embodiments, the cleaning tank structure 100 is provided with an inlet 102 and a second notch 98. The inlet 102 communicates with the cleaning tank 10 through the second notch 98. Air generated by the base station 200 can enter the cleaning tank 10 through the inlet 102, drying the mop 11 after cleaning. Alternatively, cleaning liquid in a cleaning liquid bottle within the base station 200 can enter the second notch 98 through the inlet 102, and then enter the cleaning tank 10 through the second notch 98, improving the cleaning effect of the mop 11 and the cleaning tank 10. Alternatively, if there is a large amount of sewage in the water outlet 26, the sewage overflowing from the water outlet 26 can be discharged into the inlet 102 through the second notch 98, and then discharged through the inlet 102 into a sewage bucket or sewer.

[0223] The second notch 98 can be provided on the second blocking bar 76. In this way, wind can enter the cleaning tank 10 and dry the mop 11 after cleaning.

[0224] Specifically, the inlet 102 may be disposed near the rear side of the base 20. Figure 4 In the embodiment, the second stop bar 76 may be provided with a second notch 98 near the inlet 102. A fan (not shown) may blow hot air into the cleaning tank structure 100 through the inlet 102. Since the second notch 98 is connected to the inlet 102, after the mop 11 is cleaned, the hot air may be blown toward the mop 11 while the mop 11 continues to rotate, thereby drying the mop 11.

[0225] Please combine Figures 28 to 30In 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.

[0226] 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.

[0227] Specifically, in Figure 28 In the figure, 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 close to the upper portion of the cleaning tank 10, the terminal end 108 is close to 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.

[0228] 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.

[0229] exist Figure 28 In the embodiment, 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. Along the H direction, the drainage channel 112 is located below the water supply channel 28. The water supply channel 28 is connected to the drainage channel 112, and the drainage channel 112 is connected to the water outlet 26.

[0230] In one embodiment, the dirt and the like in the water after the mop 11 is cleaned can flow into the drainage passage 112 through the water feeding passage 28, and the drainage passage 112 is communicated with the water outlet hole 26, so that the water flowing to the drainage structure 110 can flow away through the water outlet hole 26, avoiding the water from being blocked in the drainage passage 112.

[0231] Further, the drainage passage 112 can be arranged to be inclined from the end far away from the water outlet hole 26 to the end close to the water outlet hole 26, so that the dirt and the like flowing into the drainage passage 112 can be accelerated to flow to the water outlet hole 26.

[0232] In combination Figure 28 The bottom surface of the cleaning tank 10 includes an inclined surface 114. Along the thickness direction Z of the convex strip 14, the inclined surface 114 and the spiral surface 104 can be arranged on the two sides of the two convex strips 14 opposite to each other. The spiral surface 104 and the inclined surface 114 can be arranged on the two sides of the water feeding passage 28, respectively. The inclined surface 114 can be connected to the side surface of the cleaning tank 10 close to the rear side. In one embodiment, during the rotation cleaning of the mop 11, the mop 11 can be scraped with the convex strip 14 close to the inclined surface 114, and the dirt after the scraping can fall on the inclined surface 114. By arranging the inclined surface 114 to be inclined downward from the side surface of the cleaning tank 10 to the drainage structure 110, the dirt cleaned by the mop 11 can be conveniently fallen into the drainage structure 110.

[0233] In combination Figure 30 In some embodiments, the cleaning tank 10 is provided with a plurality of convex strips 14, and the plurality of convex strips 14 and the bottom surface of the cleaning tank 10 enclose the water feeding passage 28. The cleaning tank structure 100 includes a convex piece 116 protruding from the bottom surface of the cleaning tank 10. The convex piece 116 includes a blocking surface 118 facing the water feeding passage 28, and the blocking surface 118 is spaced apart from the opening of the water feeding passage 28.

[0234] Specifically, in Figure 30In the embodiment, the raised member 116 can be cylindrical in shape. The raised member 116 can be protruding from the spiral surface 104 along the axis P of the spiral surface 104. The side of the raised member 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 washing tank 10, the wastewater discharged from the water supply channel 28 can be discharged through the opening of the water supply channel 28. Because the water supply channel 28 is inclined from the water inlet 24 toward the drainage structure 110, the wastewater flowing out of the opening of the water supply channel 28 has a higher flow rate. Without any obstruction on the opposite side, the wastewater can flow onto the spiral surface 104. However, the blocking surface 118 blocks the wastewater flowing out of the opening of the water supply channel 28, thereby preventing the wastewater from falling back onto the spiral surface 104 and preventing secondary contamination.

[0235] 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.

[0236] 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 .

[0237] 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 .

[0238] 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.

[0239] 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).

[0240] The nano layer can obviously improve the cleaning degree of the cleaning tank 10, and the acid and alkali resistance and corrosion resistance of the nano layer are not inferior to the surface performance of the original material of the cleaning tank 10. Moreover, the plating process of the nano layer is cheaper than the plating process of the super-hydrophobic coating, which is conducive to reducing the cost. The cleaning degree of the cleaning tank 10 can be effectively improved by setting the nano layer, dirt is not easy to adhere to the cleaning tank 10, and bacteria are not easy to breed, so that the cleaning tank 10 is easy to clean and the user experience is improved.

[0241] Please combine Figure 10 In some embodiments, the cleaning tank structure 100 comprises a base 20, and a top surface 128 of the base 20 is formed with a first recess 130, and the first recess 130 constitutes the cleaning tank 10.

[0242] In this way, the cleaning tank 10 can be formed on the base 20 through the first recess 130, and the use of other materials is reduced.

[0243] Specifically, the top surface 128 can be concave downward to form the first recess 130, and the first recess 130 can have a circular shape, so that the cleaning tank 10 can be formed on the base 20 through the first recess 130, and the use of other materials is reduced. Alternatively, the first recess 130 can be manufactured by an integral molding process.

[0244] Please combine Figure 10 In some embodiments, the top surface 128 of the base 20 is formed with a second recess 132, and the second recess 132 constitutes a water inlet hole 24, and the water inlet hole 24 communicates with the cleaning tank 10.

[0245] In this way, the water inlet hole 24 can be formed on the base 20 through the second recess 132, and the use of other materials is further reduced.

[0246] Specifically, the base 20 can be concave downward to form the second recess 132, and the second recess 132 constitutes the water inlet hole 24, and the water inlet hole 24 communicates with the cleaning tank 10, so that the water inlet hole 24 can be formed on the base 20 through the second recess 132, and the use of other materials is reduced. Alternatively, the water inlet hole 24 can be in the form of a groove, and the second recess 132 can be manufactured by an integral molding process.

[0247] Please combine Figure 5 In some embodiments, the convex strip 14 comprises a first side surface 17, the first side surface 17 faces the side wall of the cleaning tank 10 and connects the bottom surface of the cleaning tank 10, and the minimum distance from the top of the convex strip 14 to the bottom surface 101 of the cleaning tank 10 along the first side surface 17 is greater than or equal to 2 mm.

[0248] 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 large, and the scrubbing effect of the convex strip 14 on the mop 11 can be improved.

[0249] Specifically, in Figure 5 andFigure 7 In the embodiment, 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 the present invention. 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.

[0250] 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.

[0251] 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.

[0254] In the above-mentioned base station 200 and cleaning device, when the mop 11 is placed on the ridges 14, the contact area 16 can directly contact the mop 11 when it is rotating or not. Therefore, during the process of cleaning the mop 11, the rotating 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 avoiding or reducing the chance of the cleaning tank structure 100 stinking.

The cleaning robot can use the climbing plate 126 to deliver the mop 11 into the cleaning tank 10. It will be understood 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.
