In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0031] This embodiment relates to a dust collection box, referring to Figures 1 to 3 , including a dust box body 100, the dust box body 100 has a dust collection mode and a cleaning mode. When the dust box body 100 is in the dust collection mode, the dust box body 100 is used to store the dust and garbage swept by the sweeping robot. When the dust box body 100 is in the cleaning mode, the interior of the dust box body 100 is cleaned, that is, the dust and garbage in the dust box body 100 are cleaned so that the dust box body 100 can continue to store dust and garbage.

[0032] A dust collecting chamber 101 is provided inside the dust box body 100, and an air inlet 102 for communicating with the dust collecting chamber 101 is also provided on the dust box body 100. A Hepa component 200 for filtering dust and garbage is provided in the dust collecting chamber 101, so that in the dust collecting mode, dust and garbage can be collected in the dust collecting chamber 101 through the Hepa component 200.

[0033] The side wall of the dust box body 100 is provided with a first air outlet 103 and a second air outlet 104, both of which are connected to the dust collecting chamber 101. There are two first air outlets 103, and the first air outlet 103 is located above the HEPA component 200. The second air outlet 104 is located on the side of the dust box body 100 away from the air inlet 102, and the second air outlet 104 is arranged opposite to the air inlet 102.

[0034] In addition, the present embodiment further includes a dust collection assembly (not shown in the figure) cooperating with the dust collecting box, the dust collection assembly includes a suction fan and a dust bag for collecting dust and garbage, and the dust collection assembly is detachable and connected to the second air outlet 104.

[0035] When the dust box body 100 is in the dust collection mode, the air inlet 102 and the first air outlet 103 are both in the open state, and the second air outlet 104 is in the closed state. The dust and garbage adsorbed by the sweeping robot enter the dust collecting chamber 101 through the air inlet 102 under the action of the airflow. At this time, the airflow passes through the HEPA component 200 and flows out from the first air outlet 103, and the dust and garbage entering the dust collecting chamber 101 is filtered by the HEPA component 200 in the dust collecting chamber 101. When the dust box body 100 is in the cleaning mode, the air inlet 102, the first air outlet 103 and the second air outlet 104 are all in the open state. At this time, the dust suction component is connected to the second air outlet 104, and the suction fan is driven to realize the suction of the dust collecting chamber 101, so that the dust and garbage in the dust collecting chamber 101 are sucked into the dust bag through the second air outlet 104.

[0036] Furthermore, a fan blade 300 is rotatably disposed in the dust collecting chamber 101 , the fan blade 300 is disposed along the length direction of the air inlet 102 , and the fan blade 300 is located at the air inlet 102 .

[0037] It can be understood that when the dust box body 100 is in the dust collection mode, the dust suction component generates suction on the inside of the dust collecting chamber 101, so that the external airflow flows into the dust collecting chamber 101 through the air inlet 102 and then flows to the second air outlet 104 (at this time the airflow in the dust collecting chamber 101 is laminar flow). When the airflow passes through the fan blades 300, it drives the fan blades 300 to rotate, so that the laminar flow in the dust collecting chamber 101 changes and local turbulence occurs, so that the airflow can carry away the dust and garbage located in the corners of the dust collecting chamber 101, so as to avoid the situation where the dust and garbage in the corners of the dust collecting chamber 101 are difficult to clean.

[0038] To further improve the cleaning effect of dust and garbage in the dust collection chamber 101, in this embodiment, a driving motor (not shown in the figure) for driving the fan blade 300 to rotate is further provided in the dust collection chamber 101. The output shaft of the driving motor is fixedly connected to the fan blade 300, and the driving motor is used to drive the fan blade 300 to rotate in a direction opposite to the airflow entering the air inlet 102. That is, by driving the fan blade 300 to rotate in a direction opposite to the airflow entering the air inlet 102 through the driving motor, the fan blade 300 can generate greater turbulence, so that the dust and garbage at the corners of the dust collection chamber 101 are more easily blown up, and thus the dust and garbage in the dust collection chamber 101 can be cleaned more thoroughly.

[0039] Further, the first air outlet 103 and the air inlet 102 are located on the same side of the dust box body 100, and the first air outlet 103 is located above the air inlet 102.

[0040] It can be understood that through the above settings, when the dust box body 100 is in the dust collection mode, the airflow carries the dust and garbage and enters the dust collection chamber 101 through the air inlet 102, then flows upward through the Hepa assembly 200 and flows out from the first air outlet 103, so that the flow track of the airflow is a "匸" shape, thereby making the filtering effect of the Hepa assembly 200 on the dust and garbage better, that is, the dust collection effect of the dust collection chamber 101 is better.

[0041] Further, an air inlet cover plate 105 for closing the air inlet 102 is rotatably provided on the dust box body 100. The upper side of the air inlet cover plate 105 is rotatably provided on the upper part of the air inlet 102, and the lower side of the air inlet cover plate 105 freely hangs down to close the air inlet 102.

[0042] Further, an air outlet cover plate 106 for closing the second air outlet 104 is also provided on the dust box body 100. A torsion spring 107 for cooperating with the air outlet cover plate 106 is provided at the air outlet cover plate 104, so that the air outlet cover plate 106 is kept closed in the dust collection mode under the action of the torsion spring 107.

[0043] Further, the dust box body 100 includes a dust box upper cover 108, a dust box base 109 and a dust box bottom cover 110. The dust box upper cover 108, the dust box base 109 and the dust box bottom cover 110 are mutually clamped and matched, and the Hepa assembly 200 is arranged on the dust box upper cover 108.

[0044] It can be understood that through the above settings, when it is necessary to replace the Hepa assembly 200, the dust box body 100 is disassembled into the dust box upper cover 108 and the dust box base 109, and then the Hepa assembly 200 can be disassembled from the dust box upper cover 108, and the operation is simple and convenient.

[0045] In addition, the present embodiment also provides a sweeping robot, including a robot body and a dust box as described above, wherein a accommodating cavity for accommodating the dust box is opened on the robot body, and a pressing component 111 for cooperating with the robot body is provided on the dust box, and the pressing component 111 is located above the second air outlet 104, and the detachable connection between the dust box and the robot body can be achieved through the pressing component 111.

[0046] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
