Referring to fig. 1 to 7 in combination, a dirt collecting box 100 is provided in the present utility model, and in an embodiment of the present utility model, the dirt collecting box 100 includes a box body 10 and an air guiding shell 30. The box body 10 is internally provided with a dirt collecting cavity 11, and the box body 10 is also provided with an air inlet 13 and an air outlet 15 which are communicated with the dirt collecting cavity 11; the air guide shell 30 is arranged in the dirt collecting cavity 11, one end of the air guide shell 30 is provided with an air inlet 31, the other end of the air guide shell 30 is provided with an air outlet 33 corresponding to the air outlet 15, and the air guide shell 30 is used for guiding air flow to converge to one end of the air outlet 33.

The dirt collection tank 100 may be used with a cleaning robot, which may activate a blower to drive the airflow within the dirt collection tank 100 to the blower while the cleaning robot is in operation. So that the inside of the dirt collecting chamber 11 of the dirt collecting box 100 can form negative pressure, and then the solid garbage and the liquid garbage on the ground can be sucked and removed by the negative pressure, thereby completing the cleaning work of the cleaning robot on the ground. The dirt collecting box 100 may be disposed at the tail of the robot, and since most cleaning robots are of a circular structure, the dirt collecting box 100 may be substantially semicircular (i.e., the side circumferential surface is formed of a plane and an arc surface connected thereto) to be mounted to the cleaning robot with a better fit. Of course, the present utility model is not limited thereto, and in other embodiments, the dirt collection box 100 may be disposed in the middle or other positions of the robot, and may be square or other shapes. The tank body 10 may serve as a main structure of the dirt collecting tank 100 to form a dirt collecting chamber 11 to accommodate and collect the garbage sucked by the cleaning robot after the blower is started. As described above, the case body 10 may be substantially semicircular (i.e., the side circumferential surface is formed of a plane and an arc surface connected thereto) or other formed structures, and may be provided with the air inlet 13 and the air outlet 15 on one side wall, with the air outlet 15 located above the air inlet 13. The shape of the air inlet 13 and the air outlet 15 may be any shape, that is, square, circular or other shapes. The wind guiding case 30 serves to guide the air flow to converge to one end of the air outlet 33. Specifically, after the external airflow enters the dirt collecting chamber 11 from the air inlet 13, the air inlet 31 of the air guiding housing 30 also forms suction force, so that the airflow in the dirt collecting chamber 11 can be sucked into the air guiding housing 30. Then, the air flow is driven to converge to one end of the air outlet 33 by the guiding action of the air guiding shell 30, so that the air flow is guided to be concentrated to the end of the air guiding shell 30 where the air outlet 33 is formed. When the dirt collecting box 100 is in a normal use state, the dirt collecting box 100 is defined to have an up-down direction, and the air outlet 33 may be disposed on a side surface of the air guiding shell 30 and corresponds to the air outlet 15 of the dirt collecting box 100. At this time, the air outlet 33 of the air guiding case 30 may be connected to the air outlet 15 of the dirt collecting box 100, which includes a case where one end of the air outlet 33 of the air guiding case 30 is directly installed in the air outlet 15 of the dirt collecting box 100. At this time, the air inlet 31 may be provided at the air guiding case 30 adjacent to the other wall surface provided with the air outlet 33. Since the air outlet 15 of the dirt collecting box 100 is generally disposed on the side wall of the box body 10, the air outlet 33 of the air guiding shell 30 may also be disposed on the side wall of the air guiding shell 30 to better adapt to the air outlet 15 of the dirt collecting box 100.

When the dirt collecting box 100 is used, air flow enters the dirt collecting cavity 11 from the air inlet 13 and then enters the air guiding shell 30 and then is discharged from the air outlet 33 of the air guiding shell 30 and/or the air outlet 15 of the box body 10. And, since the air guiding shell 30 can be used to guide the air flow to converge at one end of the air outlet 33, most of the air flow can flow to one end of the air outlet 33 of the air guiding shell 30 after the air flow enters the air guiding shell 30. In other words, it is ensured that most of the air flow can better flow directly to one side of the air outlet 15 of the dirt collecting box 100 after entering the air guiding shell 30, so that the air flow of the dirt collecting box 100 is concentrated, and the smoothness of the air flow is improved, and the cleaning efficiency of the cleaning robot is improved.

Referring to fig. 3, 4 and 6, in an embodiment of the present utility model, the air inlet 31 is disposed on the top wall 30a of the air guiding shell 30.

In the present embodiment, the air inlet 31 is provided on the top wall 30a in the air guide case 30 such that the air flow in the dirt collection box 100 is upward, and then enters from the top into the air guide case 30. At this time, the position of the air inlet 31 of the air guiding shell 30 is relatively higher, so that even if the sewage collected in the sewage collecting box 100 is agitated during the moving process of the cleaning robot, the agitated sewage is not easy to be sucked into the air guiding shell 30 along with the air flow from the air inlet 31, thereby avoiding the sewage from further entering the subsequent fan of the cleaning robot along with the air flow to damage the same. That is, the protection effect of the fan of the cleaning robot is improved, so that the service life of the fan is ensured. Wherein, the number of the air inlets 31 may be one, and the area of the air inlets 31 may be set relatively large at this time, so as to ensure the air passing effect while improving the convenience of the processing and forming thereof. Of course, the number of the air inlets 31 may be at least two, and the area of the air inlets 31 may be set relatively small. Furthermore, it should be noted that, in some embodiments, the air inlet 31 of the air guiding shell 30 may be disposed at the side wall and the bottom wall. In addition, in order to allow the air flow in the dirt collecting chamber 11 to more smoothly enter the air inlet 31, the top wall 30a of the air guide case 30 may be disposed to be inclined upward at a portion where the air inlet 31 is disposed in a direction from an end of the air guide case 30 away from the air outlet 33 to an end close to the air outlet 33, as shown in conjunction with fig. 4 and 6.

Referring to fig. 4 to 6, in an embodiment of the utility model, an inner side of the bottom wall 30b of the air guiding shell 30 is at least partially inclined to inhibit the liquid entrained in the air flow from flowing to one end of the air outlet 33.

In this embodiment, the inner side of at least part of the bottom wall 30b of the air guiding shell 30 is also inclined, so that even if part of the agitated sewage enters the air guiding shell 30 from the air inlet 31 of the air guiding shell 30, the sewage can flow to the end of the air guiding shell 30 away from the air outlet 33 due to the inclined inner side of the bottom wall of the air guiding shell 30, thereby facilitating the sewage to enter the subsequent fan of the cleaning robot, and further improving the protection effect on the fan of the cleaning robot. Note that, the inside of the bottom wall 30b of the air guiding case 30 is at least partially inclined, and the whole inside region of the bottom wall 30b of the air guiding case 30 is inclined, and the inside region of the bottom wall 30b of the air guiding case 30 is also inclined only partially. Secondly, the inclined arrangement comprises an inclined plane, but may of course also comprise the case of an inclined cambered surface.

Referring to fig. 5, in an embodiment of the present utility model, a bottom wall 30b of the air guiding shell 30 is provided with a drain hole 35.

In this embodiment, by the arrangement of the weeping hole 35, even the sewage entering the air guiding shell 30 can be timely discharged from the weeping hole 35, so as to further avoid entering the subsequent fan of the cleaning robot along with the airflow. Wherein, the number of the weeping holes 35 can be one, and the area of the weeping holes 35 can be relatively larger at this time, so as to ensure the liquid passing effect while improving the convenience of processing and forming the same. Of course, the number of the weep holes 35 may be at least two, and the area of the weep holes 35 may be set relatively small.

Referring to fig. 4 and fig. 5 in combination, in an embodiment of the utility model, a bottom wall 30b of the air guiding shell 30 disposed obliquely has a first end and a second end opposite to each other, the first end is lower than the second end, and the liquid leakage hole 35 is disposed at the first end; the bottom wall 30b of the air guiding shell 30 is also provided with a liquid baffle 37, and the liquid baffle 37 is positioned at the second end.

In this embodiment, the liquid baffle 37 can block the sewage entering the air guiding shell 30, so as to further avoid the sewage from entering the subsequent fan of the cleaning robot, thereby being beneficial to further improving the protection effect on the fan of the cleaning robot.

Referring to fig. 3 and 7 in combination, in an embodiment of the utility model, the dirt collection box 100 further includes a filter member 50, and the filter member 50 is disposed at the air outlet 33.

In this embodiment, the filter 50 is disposed at the air outlet 33, and the air flow entering the air guiding shell 30 can be further filtered by the filter 50, so as to reduce the possibility that the dust particles and water vapor accidentally entering the air guiding shell 30 enter the subsequent air duct of the cleaning robot through the air outlet 33, and ensure that the cleaning robot can work normally and stably. The filter 50 may be a steel mesh or a sea paper.

Referring to fig. 7 and 8 in combination, in an embodiment of the present utility model, an abutment rib 39 is disposed in the air guiding shell 30, a side of the filter 50 near the air inlet 31 abuts against the abutment rib 39, the dirt collecting box 100 further includes a mounting plate 70, the mounting plate 70 covers the air outlet 33 of the air guiding shell 30 and cooperates with the abutment rib 39 to clamp and fix the filter 50, and the mounting plate 70 further includes an air passing port 71 communicating with the air outlet 33.

In this embodiment, the abutting ribs 39 and the mounting plate 70 are used for clamping and matching the filter element 50, so that a connecting structure is not required to be arranged on the filter element 50, thereby being beneficial to ensuring that the structure of the filter element 50 is not easily damaged and better filtering operation can be performed. Of course, the mounting plate 70 may also be configured to provide a connection location for connection with the air guide housing 30. That is, in one embodiment, the connection between the air guiding shell 30 and the mounting plate 70 is mounted at the air outlet 15, and the mounting plate 70 and the dirt container 100 are connected by a buckle. At this time, the mounting plate 70 is fastened and fixed to the dirt collecting box 100, so that the components formed by the air guide shell 30, the filter element 50 and the mounting plate 70 can be quickly mounted on the dirt collecting box 100, and the convenience in manufacturing the dirt collecting box 100 is further improved. Of course, the utility model is not limited thereto, and in other embodiments, the mounting plate 70 may be mounted to the dirt collection tank 100 by a screw connection or a magnetic attachment. In order to ensure the tightness between the assembly formed by the air guiding shell 30, the filtering element 50 and the mounting plate 70 and the dirt collecting box 100, in an embodiment, the dirt collecting box 100 may further include a sealing ring 90, where the sealing ring 90 is connected to the mounting plate 70 and sleeved on the outer side of the air guiding shell 30, so as to seal between the air guiding shell 30 and the hole wall of the air outlet 15. The sealing ring 90 and the mounting plate 70 may be integrally formed, so as to improve the strength of connection therebetween and the convenience of mounting thereof. In addition, when the liquid baffle 37 is disposed in the air guiding shell 30, the liquid baffle 37 and the abutment rib 39 may be disposed opposite to each other, so that the side of the filter 50 facing away from the mounting plate 70 may be limited by abutment between the liquid baffle 37 and the abutment rib 39, thereby improving the stability of the installation of the filter 50 in the air guiding shell 30.

The utility model also provides a cleaning robot, which comprises a dirt collecting box, and the specific structure of the dirt collecting box refers to the embodiment, and because the cleaning robot adopts all the technical schemes of all the embodiments, the cleaning robot at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.
