[0033] For the purpose of the present application, technical solutions and advantages are more clearly and clearly understood, the following will be combined with the drawings and examples, the present application is further described in detail. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

The terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0035] Please refer to Figure 1 and Figure 2 , the present application provides a dust collecting box 100, which is used for cleaning robot (not shown), such as sweeping robot, sweeping and mopping integrated robot, etc. As shown in Figure 2 , the dust collecting box 100 includes a box body 10, the inside of the box body 10 is provided with a dust collecting cavity 13, and as shown in Figure 5 , the box body 10 also has a dust collecting port 101 and a dust discharging port 102 which communicate with the dust collecting cavity 13. When the cleaning robot works (sweeps the ground), the dust collecting port 101 is used for air flow into the dust collecting cavity 13, and the air flow drives the external dust, hair and other garbage into the dust collecting cavity 13, so that the garbage can be collected in the dust collecting cavity 13. The dust collecting cavity 13 is a three-dimensional space, which has a top wall and a bottom wall arranged opposite to each other, and a side wall connected with the top wall and the bottom wall. The cleaning robot can also be docked with a dust collecting base station (not shown) for dust discharging. When discharging dust, the dust collecting base station is specifically docked with the dust discharging port 102, and the air flow flows from the dust collecting port 101 to the dust collecting base station through the dust collecting cavity 13 and the dust discharging port 102 in sequence, and the garbage in the dust collecting cavity 13 is driven to flow to the dust collecting base station, so that the garbage in the dust collecting cavity 13 is cleaned.

[0036] In the present embodiment, as shown inFigure 5 and Figure 6 As shown, the dust collection chamber 13 of the box body 10 is provided with a flow divider 6. The flow divider 6 has two first guide surfaces 61 that extend gradually from the dust collection port 101 toward the opposite sidewalls of the dust collection chamber 13. That is, the distance between the two first guide surfaces 61 increases as they move away from the dust collection port 101, or in other words, the two first guide surfaces 61 gradually move closer to the dust collection port 101 from the opposite sidewalls. See below for further details. Figure 6 As shown, during dust removal, when the airflow (indicated by the dashed arrow) enters from the dust collection port 101, the airflow is guided by the two first guide surfaces 61 to the side walls on both sides of the dust collection chamber 13. The airflow on both sides can clean the edge and corner areas on both sides of the dust collection chamber 13, reducing the "dead corners" in the dust collection chamber 13. The garbage in each area of ​​the dust collection chamber 13 can enter the dust collection base as much as possible, thereby improving the dust removal effect.

[0037] The dust collection box 100 provided in this application embodiment has a diversion component 6 in its dust collection chamber 13. The diversion component 6 has two first guide surfaces 61. The two first guide surfaces 61 gradually separate and extend toward the opposite side walls of the dust collection chamber 13. During dust discharge, the garbage in each area of ​​the dust collection chamber 13 can enter the dust collection base station, reducing cleaning "dead corners", thereby improving the dust discharge effect and improving the user experience.

[0038] When the cleaning robot is working, it conforms to the ground and moves along the ground. Therefore, the dust collection box 100 also has a bottom surface facing the ground and a top surface facing away from the ground. Generally, the direction perpendicular to the ground, that is, the direction from its bottom wall to its top wall, can be understood as the height direction of the dust collection box 100.

[0039] The dust collection chamber 13 of the box body 10 can be opened and closed to allow users to manually empty the dust. Figure 2 As shown, the box body 10 includes a lower box 1 and an upper cover 2, as... Figure 2 and Figure 5 As shown, the lower box 1 includes a base plate 11 and multiple side plates 12. The side plates 12 are connected in sequence and enclose the base plate 11 to form the aforementioned dust collection chamber 13. The upper cover 2 is located at the upper opening of the lower box 1 to close the dust collection chamber 13. Opening the upper cover 2 allows the dust collection chamber 13 to be opened. The inner surface of the base plate 11 is the bottom wall of the dust collection chamber 13, the inner surface of the side plates 12 is the side wall of the dust collection chamber 13, and the lower surface of the upper cover 2 is the top wall of the dust collection chamber 13.

[0040] The shape of the side plate 12 can be set according to the shape requirements of the dust collection chamber 13 and the lower box 1. It can be a generally straight plate or an arc plate, etc.

[0041] The flow dividing member 6 is arranged on the surface of the bottom plate 11 facing the upper cover 2. Specifically, the flow dividing member 6 is recessed from the lower surface of the bottom plate 11 of the lower box 1 towards the upper cover 2, and viewed from the lower surface of the bottom plate 11, the flow dividing member 6 is in the form of a concave cavity, which can reduce the weight of the flow dividing member 6 and the lower box 1, reduce the energy consumption of the cleaning robot, and also reduce the material cost of the flow dividing member 6 and the dust collecting box 100.

[0042] In one embodiment, the upper cover 2 can be connected to the lower box 1 by a pivoting manner, and turning one end of the upper cover 2 can make the upper cover 2 rotate relative to the lower box 1, thereby exposing the dust collecting cavity 13. Of course, in other alternative embodiments, the upper cover 2 and the lower box 1 can be connected together by other manners, such as buckling, and the specific connection manner is not particularly limited.

[0043] As shown in Figure 2 , the dust collecting port 101 is arranged on one of the side plates 12 and is inclined towards the ground, or in other words, the side plate 12 on which the dust collecting port 101 is arranged is inclined towards the ground, so that the dust collecting port 101 can perform the ground cleaning operation at a certain distance from the ground during the movement of the cleaning robot.

[0044] As shown in Figure 5 , the dust discharging port 102 is arranged on the other side plate 12, which can facilitate the docking with the dust collecting base station (it can be understood that the dust discharging port 102 is closed during the operation of the cleaning robot). Alternatively, the dust discharging port 102 is arranged opposite to the dust collecting port 101. The purpose of such arrangement is that, as shown in Figure 6 , the path of the air flow during dust discharging is relatively simple and generally symmetrical, and the situation that the length of the paths on both sides is greatly different and the speed and pressure of the air flow are greatly different does not occur, which can further reduce the formation of "dead corners" in the dust collecting cavity 13.

[0045] Of course, it can be understood that during the operation of the cleaning robot, the air flow enters the dust collecting port 101 and then flows out through the air outlet 103 formed on the dust collecting box 100 to realize the circulation of the air flow. The air outlet 103 can be arranged on the side of the box body 10, because in the cleaning robot, the surface of the upper part of the dust collecting box 100 is usually covered by other structures as a whole to maintain the aesthetic appearance. Specifically, the air outlet 103 can be arranged on the side plate 12 of the lower box 1, or the air outlet 103 is arranged on the side of the upper cover 2, as shown in Figure 2 .

[0046] As shown in Figure 2 and Figure 4As shown, the dust collecting box 100 further comprises a filter assembly 5, which is arranged in the dust collecting cavity 13 before the air outlet 103, so that the garbage and the like carried by the air flow formed when the cleaning robot works is blocked in the dust collecting cavity 13 by the filter assembly 5.

[0047] The specific arrangement position of the filter assembly 5 is arranged according to the shape of the dust collecting cavity 13 and the position and shape of the flow dividing member 6. As shown in Figure 2 and Figure 4 shown in the embodiment, the filter assembly 5 is arranged above the flow dividing member 6 and fixed on the upper cover 2, and the air outlet 103 is arranged on the upper cover 2, so that the garbage and the like entering the dust collecting cavity 13 can reach above the flow dividing member 6 and be further blocked below the filter assembly 5, and the air continues to pass through the upper cover 2 after passing through the filter assembly 5, and finally is discharged through the air outlet 103 of the upper cover 2.

[0048] As shown in Figure 1 , Figure 2 and Figure 3 shown, a cover plate 3 is further arranged above the filter assembly 5, which is connected to the upper cover 2 and covers the filter assembly 5. When the filter assembly 5 needs to be cleaned, the upper cover 2 is opened, and then the filter assembly 5 can be exposed and taken out. The cover plate 3 can be connected to the upper cover 2 by snap connection, pivot connection or the like, which is not particularly limited here.

[0049] As shown in Figures 3 to 5 , the flow dividing member 6 has an upper surface 63 arranged towards the filter assembly 5, which is connected to the upper edges of the two first flow guiding surfaces 61.

[0050] In one embodiment, as shown in Figures 2 to 4 , the upper surface 63 is a plane, and optionally, the upper surface 63 is parallel to the lower surface of the filter assembly 5 or is inclined relative to the lower surface of the filter assembly 5. Alternatively, in other embodiments, the upper surface 63 can be a convex surface to reduce the accumulation of garbage on the upper surface 63.

[0051] As shown in Figure 3 , the upper surface 63 has a gap 104 with the lower surface of the filter assembly 5. According to the foregoing, a part of the garbage will accumulate between the upper surface 63 and the filter assembly 5, and the gap 104 is used to allow the air flow to pass through and take away the garbage accumulated there during dust removal.

[0052] The height D of the gap 104 is in the range of 3mm to 5mm, or in other words, the distance between the filter assembly 5 and the upper surface 63 is in the range of 3mm to 5mm. In this range, it can ensure that there is a large enough air flow pressure to take away the garbage here during dust removal, and it can also avoid that the air flow pressure on both sides of the dust collecting cavity 13 is too small to affect the cleaning of the "dead angle" on both sides.

[0053] As shown in Figure 4 The two first flow guide surfaces 61 are arranged in a gradually expanding manner from top to bottom, that is, in the direction from the filter assembly 5 to the bottom plate 11, the two first flow guide surfaces 61 of the flow distribution piece 6 are both inclined outward, that is, from top to bottom, the two first flow guide surfaces 61 are gradually separated. The purpose of such arrangement is that, during dust removal, the airflow is distributed to both sides by the first flow guide surfaces 61, and at the same time, the airflow can also flow upward along the first flow guide surfaces 61, so that the airflow can reach the upper surface 63 of the flow distribution piece 6, and can carry the garbage and the like accumulated on the upper surface 63 of the flow distribution piece 6 into the dust collection base station.

[0054] As shown in Figure 5 The included angle a between the two first flow guide surfaces 61 is set according to the overall shape of the dust collection cavity 13. Assuming that the direction from the dust collection port 101 to the dust removal port 102 is the width direction, the direction perpendicular to the width direction and the height direction is the length direction, if the length of the dust collection cavity 13 is significantly larger, and the dust collection cavity 13 is in the form of a long strip extending along the length direction, then the included angle between the two first flow guide surfaces 61 can be larger, such as greater than 90°, if the width of the dust collection cavity 13 is significantly larger, and the dust collection cavity 13 is in the form of a long strip extending along the width direction, then the included angle between the two first flow guide surfaces 61 can be smaller, such as less than 90°.

[0055] In the embodiment, the dust collection box 100 is applied to cleaning robots such as floor cleaning robots and sweeping and mopping integrated machines, and the difference between the length and the width of the dust collection box 100 cannot be too large due to the overall shape of the cleaning robot. Therefore, in the embodiment, the included angle a between the two first flow guide surfaces 61 is greater than 90°, specifically 100°-170°. Since the first flow guide surfaces 61 are arranged in an outwardly inclined manner from top to bottom, assuming that the edge of the first flow guide surface 61 connected with the upper surface 63 is the upper edge, and the edge connected with the bottom plate 11 is the lower edge, then the angle between the two first flow guide surfaces 61 of 100°-170° can refer to the included angle between the two upper edges of 100°-170°, or the angle between the two lower edges of 100°-170°, or both the included angle between the two upper edges and the included angle between the two lower edges of 100°-170°. In specific applications, the specific value of the included angle a can be set in combination with the product, which is not particularly limited here.

[0056] Please refer to Figures 3 to 5As shown, in one embodiment, the flow distributor 6 also has two second flow guide surfaces 62, the distance between the two second flow guide surfaces 62 increases away from the dust outlet 102, that is, the two second flow guide surfaces 62 gradually converge towards the dust outlet 102. This makes the garbage in the "dead angle" area of the dust collection cavity 13 swept by the airflow can be smoothly guided to the dust outlet 102, and then into the dust collection base station. The upper edge of the second flow guide surface 62 is also connected with the upper surface 63, and the lower edge of the second flow guide surface 62 is connected with the bottom plate 11.

[0057] As Figure 4 shown, the second flow guide surface 62 is arranged in a gradually expanding manner from top to bottom, that is, in the direction from the filter assembly 5 to the bottom plate 11, both of the two second flow guide surfaces 62 of the flow distributor 6 are inclined outward, that is, from top to bottom, the two second flow guide surfaces 62 are gradually separated. The purpose of such arrangement is that when the dust is discharged, the airflow above the upper surface 63 is inclined to transition to the surface of the bottom plate 11 under the guidance of the second flow guide surface 62, avoiding the formation of "dead angle" at the lower edge of the second flow guide surface 62, and further ensuring the dust discharge effect.

[0058] In the present embodiment, the angle between the two second flow guide surfaces 62 is greater than 90°, specifically 100°-170°. Among them, since the second flow guide surface 62 is arranged in an outwardly inclined manner from top to bottom, assuming that the edge of the second flow guide surface 62 connected with the upper surface 63 is its upper edge, and the edge connected with the bottom plate 11 is its lower edge, then the angle between the two second flow guide surfaces 62 of 100°-170° can refer to the angle between the two upper edges of 100°-170°, or the angle between the two lower edges of 100°-170°, or both the angle between the two upper edges and the angle between the two lower edges are 100°-170°. In specific applications, the specific value of the angle between the two second flow guide surfaces 62 can be set in combination with the product, which is not particularly limited here.

[0059] Optionally, the angle α between the two first flow guide surfaces 61 is equal to the angle between the two second flow guide surfaces 62. Such arrangement can make the overall shape of the flow distributor 6 more regular, facilitating its manufacture.

[0060] The angle β between the first flow guide surface 61 and the adjacent second flow guide surface 62 is calculated according to the formula of the interior angle of a polygon, which will not be repeated here.

[0061] Of course, as Figure 3 and Figure 4As shown, the two first flow guide surfaces 61 are connected by arc-shaped transition surfaces to form smooth transitions; the two second flow guide surfaces 62 are connected by arc-shaped transition surfaces to form smooth transitions; the first flow guide surfaces 61 and the second flow guide surfaces 62 are connected by arc-shaped transition surfaces to form smooth transitions; the first flow guide surfaces 61 and the upper surface 63 are connected by arc-shaped transition surfaces to form smooth transitions; and the second flow guide surfaces 62 and the upper surface 63 form smooth transitions. In this way, the formation of "dead corners" in the dust collection cavity 13 can be further avoided, the dust discharge effect is ensured, and the manufacturing of the box body 10 is facilitated.

[0062] As shown in the drawings, Figure 5 in one embodiment, the ratio of the length L1 of the flow distribution member 6 to the length L of the dust collection cavity 13 is 0.6-0.8. That is, the distance between the two connection points formed by the connection of the first flow guide surfaces 61 and the adjacent second flow guide surfaces 62 accounts for 0.6-0.8 of the length L of the dust collection cavity 13 in the direction perpendicular to the line connecting the dust inlet 101 and the dust outlet 102. Within this range, the length of the flow distribution member 6 is appropriate, neither too small to make the flow distribution effect insignificant nor too large to occupy too much space.

[0063] Similarly, referring to Figure 5 in one embodiment, the ratio of the width W1 of the flow distribution member 6 to the width W of the dust collection cavity 13 is 0.1-0.8. That is, the distance between the connection point of the two first flow guide surfaces 61 and the connection point of the two second flow guide surfaces 62 accounts for 0.1-0.8 of the width W of the dust collection cavity 13 in the direction from the dust inlet 101 to the dust outlet 102. Within this range, the width of the flow distribution member 6 is appropriate, neither too small to make the flow distribution effect insignificant nor too large to occupy too much space.

[0064] Referring to Figure 5 and Figure 6 in one embodiment, a water tank and a water inlet 15 communicating with the water tank are further formed on the dust collection box 100. As shown, Figures 2 to 4 a mop support 4 is fixedly installed on the bottom of the lower box 1, and the mop support 4 is used for detachably connecting with a mop (not shown). The water tank is used for providing clean water to the mop in the mopping mode of the cleaning robot to scrub the ground during movement. Therefore, the cleaning robot is a sweeping and mopping integrated robot.

[0065] In this embodiment, the water tank is defined by the lower box 1 and the mop support 4 below the lower box 1, that is, the space between the lower box 1 and the mop support 4 serves as a water storage cavity 14 of the water tank, as shown. Figure 4 Referring to Figure 5 and Figure 6As shown, the water inlet 15 is arranged on the lower box 1 and opens upward, located at one side of the dust collecting cavity 13, and the water storage cavity 14 extends from the water inlet 15 to below the dust collecting cavity 13.

[0066] The mop support 4 and the lower box 1 can be two independently manufactured structures which are sealingly connected together to form the water tank.

[0067] As shown, the water inlet 15 is provided with a rubber plug 16 for opening and sealing the water inlet 15. Figure 1
