DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0031] The present application provides a cleaning system and a cleaning robot to solve the problem in the related art that in order to collect garbage in the dust box of the cleaning robot, a fan generally needs to be installed in the base station, and the price of the fan in the base station is relatively high, which increases the cost of the cleaning system.

[0032] In a first aspect, the present application provides a cleaning system, such as Figure 1 As shown, the cleaning system includes a base station 80 and a cleaning robot; the cleaning robot may be a sweeping robot, a sweeping and mopping robot, a mopping robot, etc., and the present application does not specifically limit the type of the cleaning robot. The base station 80 can clean up the garbage in the cleaning robot, which can reduce the number of times the user cleans the garbage in the dust collection chamber 21. Of course, according to actual needs, the base station 80 can also have the function of providing charging, rehydration, mopping and other services for the cleaning robot, and the present application does not specifically limit the type of the base station 80.

[0033] Specifically, the base station 80 has a dust storage chamber 82 and a dust suction port 81 connected to the dust storage chamber 82 ; the cleaning robot includes a body 10 , a dust collection box 20 , a fan 30 and an airflow reversing mechanism 40 .

[0034] The body 10 is the main structure of the cleaning robot, and is used to provide installation space and support for components such as the dust box 20 and the fan 30 .

[0035] The dust box 20 is installed on the body 10, and the dust box 20 has a dust collecting chamber 21, a dust inlet 22 connected to the dust collecting chamber 21, a dust outlet 23 and a first dust box air port 24; the dust box 20 is a device for storing garbage in the cleaning robot. When the cleaning robot performs garbage cleaning work, the collected garbage enters the dust collecting chamber 21 through the dust inlet 22 and is stored in the dust collecting chamber 21.

[0036] The fan 30 is installed on the body 10 and is used to generate airflow. The present application does not impose any specific restrictions on the specific size and model of the fan 30 .

[0037] The airflow reversing mechanism 40 is installed on the machine body 10 , and the airflow reversing mechanism 40 is used to change the flow direction of the airflow generated by the fan 30 .

[0038] Among them, the cleaning robot has a dust collection state (such as Figure 2 and Figure 3 ) and dust removal status (such as Figure 1 ), when the cleaning robot is in the dust collecting state, the airflow reversing mechanism 40 is used to make the airflow generated by the fan 30 drive the garbage into the dust collecting chamber 21 from the dust inlet 22; when the cleaning robot is in the dust discharging state, the dust suction port 81 is connected with the dust collecting chamber 21 through the dust outlet 23, and the airflow reversing mechanism 40 is used to make the airflow generated by the fan 30 discharge the garbage in the dust collecting chamber 21 from the dust outlet 23 to the dust storage chamber 82.

[0039] It should be noted that the airflow reversing mechanism 40 can change the flow direction of the airflow generated by the fan 30, thereby changing the flow direction of the airflow in the dust collecting chamber 21. When the cleaning robot performs cleaning work, it is necessary to collect garbage on the bottom surface and other positions into the dust collecting chamber 21. Therefore, the cleaning robot needs to be in a dust collecting state. At this time, the flow direction of the airflow generated by the fan 30 in the dust collecting chamber 21 can be changed by the airflow reversing mechanism 40, so that the airflow generated by the fan 30 in the dust collecting chamber 21 flows from the dust inlet 22 to the first dust box air outlet 24 (such as Figures 2 to 4 As shown in the figure), the airflow can generate negative pressure at the dust inlet 22, so that the garbage can be sucked into the dust collecting chamber 21 through the dust inlet 22. At this time, the first dust box air port 24 is used as the air outlet of the dust collecting box 20; when it is necessary to use the base station 80 to clean the garbage in the dust collecting chamber 21, it is necessary to transfer the garbage in the dust collecting chamber 21 to the middle dust storage chamber 82 of the cleaning robot. After the cleaning robot is moved to the preset position on the base station 80, the cleaning robot enters the dust exhaust state. At this time, the dust outlet 23 of the cleaning robot is connected with the dust suction port 81, and the dust outlet 23 is connected with the dust storage chamber 82 through the dust suction port 81. At this time, the flow direction of the airflow generated by the fan 30 in the dust collecting chamber 21 can be changed by the airflow reversing mechanism 40 (as shown in the figure). Figure 1 , Figures 5 to 7 As shown), the airflow generated by the fan 30 in the dust collecting chamber 21 flows toward the dust outlet 23, so that the airflow can be used to transfer the garbage in the dust collecting chamber 21 to the dust storage chamber 82 to achieve the cleaning of the dust collecting chamber 21.

[0040] It can be understood that in the present application, by setting an airflow reversing mechanism 40 in the cleaning robot, the fan 30 in the cleaning robot can realize both the dust collection function and the dust discharge function of the cleaning robot. Therefore, there is no need to set an additional fan 30 in the base station 80, which can reduce the cost of the cleaning system.

[0041] It should also be noted that the dust storage chamber 82 in the base station 80 can be a dust bag 83 (such as Figure 1), the dust bag 83 is accommodated in the accommodating cavity of the base station 80, the dust bag 83 is provided with a sewage inlet connected to the dust storage cavity 82, the dust suction port 81 is connected to the sewage inlet, and the dust bag 83 is provided with a plurality of filter holes, the dust storage cavity 82 is connected to the accommodating cavity through the filter holes, when the cleaning robot is in the dust collecting state, the garbage in the dust collection cavity 21 is transferred to the dust storage cavity 82 by the airflow, and the filter holes can realize the gas flow between the dust storage cavity 82 and the accommodating cavity, and at the same time, the filter holes can filter and intercept large-sized garbage such as large-sized dust particles, fruit peels and paper scraps in the dust storage cavity 82, so as to prevent large-sized garbage from being sucked into the fan 30 and causing damage to the fan 30. Taking the dust bag 83 as a soft filter bag as an example, the filter holes are the mesh holes on the filter bag. Of course, the dust bag 83 can also be a dust bag 83 combined with a soft filter bag provided on the outer shell of the supporting skeleton. There are many choices for the material of the dust bag 83, such as water-repellent and oil-proof felt, polyester needle-punched felt, triple-proof polyester needle-punched felt, etc.

[0042] Specifically, Figure 2 , Figure 3 , Figure 4 as well as Fig.12 As shown, the fan 30 has an air inlet 31 and an air outlet 32. When the cleaning robot is in the dust collecting state, the air inlet 31 is connected to the first dust box air port 24, and the air outlet 32 ​​is connected to the atmosphere. As the name implies, the air inlet 31 is an opening for air intake when the fan 30 is working, and the air outlet 32 ​​is an opening for air discharge when the fan 30 is working. When the cleaning robot is in the dust collecting state, the fan 30 is started. At this time, the airflow generated by the fan 30 passes through the dust inlet 22, the dust collecting chamber 21, the first dust box air port 24, the air inlet 31 and the air outlet 32 ​​in sequence. The airflow generates negative pressure in the dust collecting chamber 21, and negative pressure can be generated at the dust inlet 22, so that the garbage in the dust collecting chamber 21 is sucked into the dust collecting chamber 21 through the dust inlet 22. At this time, the first dust box air port 24 is used as the air outlet of the dust collecting box 20.

[0043] like Figures 5 to 7 As shown, it should be noted that when the cleaning robot is in the dust discharge state, the garbage in the dust collecting chamber 21 can be transferred to the dust storage chamber 82 of the base station 80 through a variety of dust discharge methods.

[0044] like Figure 5 , Fig.10 as well as Fig.13As shown, in the first dust exhaust mode, the base station 80 also has a base station air outlet 84 connected to the dust storage chamber 82. When the cleaning robot is in the dust exhaust state, the air inlet 31 is connected to the dust storage chamber 82 through the base station air outlet 84, and the air outlet 32 ​​is connected to the atmosphere; at this time, the airflow generated by the fan 30 passes through the dust collecting chamber 21, the dust outlet 23, the dust suction port 81, the dust storage chamber 82, the base station air outlet 84, the air inlet 31 and the air outlet 32 ​​in sequence, and the air in the dust storage chamber 82 is sucked by the fan 30, so that a negative pressure is formed in the dust storage chamber 82, so that the garbage in the dust collecting chamber 21 is transferred to the dust storage chamber 82 by the airflow.

[0045] like Figure 6 and Fig.11 As shown, in the second dust exhaust mode, when the cleaning robot is in the dust exhaust state, the air inlet 31 is connected to the atmosphere, and the air outlet 32 ​​is connected to the first dust box air port 24; at this time, the airflow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the first dust box air port 24, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81 and the dust storage chamber 82 in sequence, and air is blown into the dust collecting chamber 21 by the fan 30, so that a positive pressure is formed in the dust collecting chamber 21, so that the garbage in the dust collecting chamber 21 is transferred to the dust storage chamber 82 by the airflow, and at this time, the first dust box air port 24 is used as the air inlet of the dust collecting box 20.

[0046] like Figure 6 and Fig.14 As shown, in the second dust discharge mode, the dust box 20 can also be configured to have a second dust box air port 25 connected to the dust collecting chamber 21. When the cleaning robot is in the dust discharge state, the air inlet 31 is connected to the atmosphere, and the air outlet 32 ​​is connected to the second dust box air port 25. At this time, the airflow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the second dust box air port 25, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81 and the dust storage chamber 82 in sequence, and the fan 30 blows air into the dust collecting chamber 21, so that a positive pressure is formed in the dust collecting chamber 21, so that the garbage in the dust collecting chamber 21 is transferred to the dust storage chamber 82 by the airflow. At this time, the second dust box air port 25 is used as the air inlet of the dust box 20. It should be noted that the second dust box air port 25 is an opening in the dust box 20 that is different from the first dust box air port 24, and the second dust box air port 25 and the first dust box air port 24 are arranged at different positions of the dust box 20.

[0047] like Figure 1 and Figure 7As shown, in the third dust exhaust mode, the base station 80 also has a base station air outlet 84 connected to the dust storage chamber 82; when the cleaning robot is in the dust exhaust state, the air inlet 31 is connected to the dust storage chamber 82 through the base station air outlet 84, and the air outlet 32 ​​is connected to the first dust box air inlet 24; at this time, the air flow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the first dust box air inlet 24, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81, the dust storage chamber 82, the base station air outlet 84 and the air inlet 31 in sequence to form an air flow cycle, and the fan 30 forms a positive pressure in the dust collecting chamber 21, and at the same time forms a negative pressure in the dust storage chamber 82, so that the garbage in the dust collecting chamber 21 can be discharged into the dust storage chamber 82 faster. At this time, the first dust box air inlet 24 is used as the air inlet of the dust collecting box 20.

[0048] like Figure 7 and Fig.15 As shown, in the third dust exhaust mode, it can also be set that the dust box 20 also has a second dust box air inlet 25 connected to the dust collecting chamber 21. When the cleaning robot is in the dust exhaust state, the air inlet 31 is connected to the dust storage chamber 82 through the base station air outlet 84, and the air outlet 32 ​​is connected to the second dust box air inlet 25; at this time, the air flow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the second dust box air inlet 25, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81, the dust storage chamber 82, the base station air outlet 84 and the air inlet 31 in sequence to form an air flow cycle. The fan 30 forms a positive pressure in the dust collecting chamber 21 and a negative pressure in the dust storage chamber 82. At this time, the second dust box air inlet 25 is used as the air inlet of the dust box 20.

[0049] In some embodiments of the present application, the first dust box air inlet 24 and / or the second dust box air inlet 25 is provided with a filter element 61, which can intercept garbage in the dust collecting chamber 21 to prevent the garbage in the dust collecting chamber 21 from being sucked out of the first dust box air inlet 24 and the second dust box air inlet 25 by the fan 30. At the same time, the filter element 61 can ensure the gas circulation between the dust collecting chamber 21 and the fan 30. The filter element 61 can be a device such as a filter element.

[0050] In some embodiments of the present application, when the dust box 20 has both the first dust box air inlet 24 and the second dust box air inlet 25, an opening and closing mechanism for opening and closing the first dust box air inlet 24 and the second dust box air inlet 25 can be provided at the first dust box air inlet 24 and the second dust box air inlet 25. The opening and closing mechanism can be a switch 50 valve or a mechanism such as a cover plate as follows for opening and closing the dust inlet 22 and the dust outlet 23. The opening and closing mechanism can enable the first dust box air inlet 24 to be opened and the second dust box air inlet 25 to be closed when the cleaning robot is in the dust collection state, and the first dust box air inlet 24 to be closed and the second dust box air inlet 25 to be opened when the cleaning robot is in the dust discharge state, so as to prevent the second dust box air inlet 25 from leaking when the cleaning robot is in the dust collection state, and also to prevent the first dust box air inlet 24 from leaking when the cleaning robot is in the dust discharge state.

[0051] In some embodiments of the present application, taking the direction in which the cleaning robot enters the base station 80 as the forward direction as an example, the fan 30 can be located in the forward direction of the dust box 20, the first dust box air port 24 is located on the side of the dust box 20 close to the fan 30, and the dust inlet 22 is located on the side of the dust box 20 away from the fan 30. This design allows the garbage to be evenly distributed in the entire space of the dust chamber 21 when the cleaning robot is in the dust collection state, and can prevent the garbage from accumulating only in the corner or one side of the dust chamber 21. Further, the dust outlet 23 is located on the side of the dust box 20 close to the fan 30, and when the cleaning robot is in the dust discharge state, the dust suction port 81 on the base station 80 is arranged opposite to the dust outlet 23, so as to facilitate the docking and communication between the dust outlet 23 and the dust suction port 81.

[0052] In an embodiment of the present application, two dust outlets 23 may be provided, and the two dust outlets 23 are respectively located on both sides of the first dust box air inlet 24 to enhance the dust removal capability of the cleaning robot.

[0053] It should be noted that there are many ways for the airflow reversing mechanism 40 to achieve airflow reversal, such as Figures 1 to 3 as well as Figures 8 to 11 As shown, the airflow reversing mechanism 40 realizes airflow reversal in the first airflow reversing mode, and the fan 30 is rotatably connected to the body 10 .

[0054] The airflow reversing mechanism 40 includes a driving member 41 , which is mounted on the body 10 and is transmission-connected to the fan 30 . The driving member 41 is used to drive the fan 30 to rotate so as to adjust the directions of the air inlet 31 and the air outlet 32 ​​.

[0055] It is understandable that when the cleaning robot is in the dust collecting state (such as Figure 2 and Figure 3 ), the driving member 41 drives the fan 30 to rotate to adjust the directions of the air inlet 31 and the air outlet 32, so that the air inlet 31 of the fan 30 is connected with the first dust box air port 24, and the air outlet 32 ​​is connected with the atmosphere, and the fan 30 starts to extract the air in the dust collecting chamber 21; when the cleaning robot is in the dust exhaust state (such as Figure 1 , Figures 8 to 11 ), the driving member 41 drives the fan 30 to rotate, adjusts the direction of the air inlet 31 and the air outlet 32, and when the air inlet 31 is connected to the base station air outlet 84, and the air outlet 32 ​​is connected to the atmosphere, the cleaning robot performs dust removal in the first dust removal mode (such as Fig.10 ); when the air inlet 31 is connected to the atmosphere, and the air outlet 32 ​​is connected to the first dust box air port 24 or the second dust box air port 25, the cleaning robot discharges dust in the second dust discharge mode (such as Fig.11); when the air inlet 31 is connected to the air outlet 84 of the base station, and the air outlet 32 ​​is connected to the first dust box air outlet 24 or the second dust box air outlet 25, the cleaning robot discharges dust in a third dust discharge manner (such as Figure 1 , Figure 8 and Fig. 9 ).

[0056] It should also be noted that when the cleaning robot is in the dust collection state, the air inlet 31 can be directly connected to and communicated with the first dust box air port 24, and the air inlet 31 can also be connected to the first dust box air port 24 through a pipe channel; when the cleaning robot is in the dust discharge state, the air inlet 31 and the air outlet 32 ​​can be directly connected to and communicated with the corresponding interface on the dust box 20 or / and the base station 80, and the air inlet 31 and the air outlet 32 ​​can also be connected to the corresponding interface on the dust box 20 or / and the base station 80 through a pipe channel. It should also be noted that the driving member 41 can be a motor, and the output shaft of the motor can be directly connected to the housing of the fan 30 to drive the fan 30 to rotate using the motor; of course, it can also be connected through a transmission component 42 (such as a gear component) such as a gear component. Figure 3 ) The output shaft of the motor is connected to the housing of the fan 30, and the motor is used to drive the transmission assembly 42 to move, so as to drive the fan 30 to rotate. The specific model of the motor can be selected according to time requirements, and this application does not make specific limitations.

[0057] In one embodiment of the present application, the cleaning robot also includes a switch 50, which is installed on the body 10 or the dust box 20. The switch 50 is used to detect the position of the fan 30. When the fan 30 rotates to press the switch 50, the cleaning robot is in a dust collection state or a dust discharge state.

[0058] It can be understood that the switch 50 is used to detect the position of the fan 30. When the driving member 41 drives the fan 30 to move to the specified position, the switch 50 will be pressed by the fan 30. At this time, the air inlet 31 and the air outlet 32 ​​are connected to the corresponding interfaces on the dust box 20 and / or the base station 80, and the fan 30 will be started. When the switch 50 is not pressed by the fan 30, the fan 30 will not be started. For example, when the fan 30 moves to the first specified position, the switch 50 will be pressed by the fan 30. At this time, the air inlet 31 is connected to the first dust box air port 24, and the air outlet 32 ​​is connected to the atmosphere, and the cleaning robot is in a dust collecting state; when the fan 30 moves to the second designated position, the air inlet 31 and the air outlet 32 ​​are connected to the corresponding interfaces on the dust collecting box 20 and / or the base station 80, and the switch 50 is also pressed by the fan 30, and the cleaning robot is in a dust exhausting state. The switch 50 can be a switch 50. The specific working principle of the switch 50 has been disclosed in the relevant technology and will not be repeated in this application.

[0059] It should also be noted that only one switch 50 may be provided, and the movement of the fan 30 to the first designated position or the second designated position is determined by the number of times the fan 30 presses the switch 50. For example, when the fan 30 presses the switch 50 for the first time, the fan 30 moves to the first designated position, when the fan 30 presses the switch 50 for the second time, the fan 30 moves to the second designated position, and when the fan 30 presses the switch 50 for the third time, the fan 30 moves to the first designated position, and so on. Two switches 50 may also be provided, and one switch 50 is pressed when the fan 30 moves to the first designated position, and the other switch 50 is pressed when the fan 30 moves to the second designated position.

[0060] It should also be noted that the operation of the drive component 41 and the fan 30 can be controlled by the control module of the cleaning robot or the control module of the base station 80; for example, when the cleaning robot is switched from a dust removal state to a dust collection state, the control center of the cleaning robot or the control center of the base station 80 detects that the state of the cleaning robot has changed from a dust removal state to a dust collection state, and the control center of the cleaning robot or the control center of the base station 80 controls the drive component 41 to start working, and the drive component 41 drives the fan 30 to rotate. When the fan 30 moves to the first specified position, the moment switch 50 is pressed, and the control center of the cleaning robot or the control center of the base station 80 receives the first arrival instruction, and controls the drive component 41 to stop working, and controls the fan 30 to start. When the cleaning robot switches from a dust collection state to a dust discharge state, the control center of the cleaning robot or the control center of the base station 80 detects that the state of the cleaning robot changes from the dust collection state to the dust discharge state, and the control center of the cleaning robot or the control center of the base station 80 controls the driving component 41 to start working, and the driving component 41 drives the fan 30 to rotate. When the fan 30 moves to the second designated position, the moment switch 50 is pressed, and the control center of the cleaning robot or the control center of the base station 80 receives the second arrival instruction, and controls the driving component 41 to stop working, and controls the fan 30 to start.

[0061] In some embodiments of the present application, Figures 12 to 16 As shown, the airflow reversing mechanism 40 includes an air duct structure and an air duct switching assembly.

The airflow in the air duct structure enters and exits the dust collecting chamber 21 through the first dust box air port 24, and generates an airflow of a corresponding direction in the dust collecting chamber 21. By changing the flow direction of the airflow generated by the fan 30 in the air duct structure through the air duct switching component, the flow direction of the airflow generated by the fan 30 in the dust collecting chamber 21 can be changed, thereby enabling the cleaning robot to switch between the dust collection state and the dust exhaust state.

When the cleaning robot is in the dust exhaust state, the air duct switching component connects the first air inlet 431 with the third air inlet 433, while blocking the first air inlet 431 and the second air inlet 432, and the first air outlet 441 is connected to the third air outlet 443, while blocking the first air outlet 441 and the second air outlet 442, so that the air inlet 31 is connected to the atmosphere, and the air outlet 32 ​​is connected to the dust collecting chamber 21. At this time, the airflow generated by the fan 30 passes through the third air inlet 433, the first air inlet 431, the air inlet 31, the air outlet 32, the first air outlet 441, the third air outlet 443, the second dust box air inlet 25, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81 and the dust storage chamber 82 in sequence.

[0072] Among them, when the cleaning robot is in the dust exhaust state, the base station air outlet 84 is connected to the third air inlet 433, the third air outlet 443 is connected to the first dust box air outlet 24, the air duct switching component connects the first air inlet 431 with the third air inlet 433, and blocks the first air inlet 431 from the second air inlet 432, the first air outlet 441 is connected to the third air outlet 443, and blocks the first air outlet 441 from the second air outlet 442, so that The air inlet 31 is connected to the dust storage chamber 82, and the air outlet 32 ​​is connected to the dust collecting chamber 21. At this time, the airflow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the first air outlet 441, the third air outlet 443, the first dust box air inlet 24, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81, the dust storage chamber 82, the base station air outlet 84, the third air inlet 433, the first air inlet 431 and the air inlet 31 in sequence to form an airflow cycle.

[0073] In the third dust exhaust mode, it can also be set that the dust box 20 also has a second dust box air port 25 connected to the dust collecting chamber 21, the base station air outlet 84 is connected to the third air inlet 433, and the third air outlet 443 is connected to the second dust box air port 25. When the cleaning robot is in the dust exhaust state, the air duct switching component connects the first air inlet 431 with the third air inlet 433, and blocks the first air inlet 431 from being connected to the second air inlet 432, and the first air outlet 441 is connected to the third air outlet 443, and blocks the first The air outlet 441 and the second air outlet 442 make the air inlet 31 connected with the dust storage chamber 82, and the air outlet 32 ​​is connected with the dust collecting chamber 21. At this time, the airflow generated by the fan 30 passes through the air inlet 31, the air outlet 32, the first air outlet 441, the third air outlet 443, the second dust box air inlet 25, the dust collecting chamber 21, the dust outlet 23, the dust suction port 81, the dust storage chamber 82, the base station air outlet 84, the third air inlet 433, the first air inlet 431 and the air inlet 31 in sequence to form an airflow cycle.

[0074] Continue to see Fig.15 As shown, in some embodiments of the present application, the air duct switching assembly includes a first driving mechanism, a first switching baffle 45 , a second driving mechanism and a second switching baffle 46 .

[0075] The first switch baffle 45 is disposed in the air intake duct 43, and the first driving mechanism is in transmission connection with the first switch baffle 45 to drive the first switch baffle 45 to move relative to the air intake duct 43, so that the first switch baffle 45 is in a first preset position (such as Fig.12 ) and a second preset position (such as Figures 13 to 15 ), when the first switching baffle 45 is located at the first preset position, the first dust box air inlet 24 is connected to the air inlet 31; when the first switching baffle 45 is located at the second preset position, the first switching baffle 45 blocks the first dust box air inlet 24 and the air inlet 31.

[0076] The second switch baffle 46 is disposed in the outlet air duct 44, and the second driving mechanism is in transmission connection with the second switch baffle 46 to drive the second switch baffle 46 to move relative to the outlet air duct 44, so that the second switch baffle 46 is in a third preset position (such as Fig.12 and Fig.13 ) and the fourth preset position (such as Fig.14 and Fig.15 ), when the second switching baffle 46 is located at the third preset position, the air outlet 32 ​​is connected to the atmosphere; when the second switching baffle 46 is located at the fourth preset position, the second switching baffle 46 blocks the air outlet 32 ​​and the atmosphere.

[0077] It is understandable that by moving the first switching baffle 45, the air inlet 31 and the first dust box air outlet 24 can be switched on and off, so that the direction of the airflow in the air inlet duct can be changed by the first switching baffle 45; by moving the second switching baffle 46, the air outlet 32 ​​and the atmosphere can be switched on and off, so that the direction of the airflow in the air outlet duct can be changed by the second switching baffle 46. The first driving mechanism and the second driving mechanism can be an electrical driving member 41 such as a motor, the first driving mechanism can also be a manual member connected to the first switching baffle 45 and extending to the outside of the machine body 10, and the second driving mechanism can also be a manual member connected to the second switching baffle 46 and extending to the outside of the machine body 10, and the user manually turns the manual member to drive the first switching baffle 45 and the second switching baffle 46 to move.

[0078] Specifically, Fig.12 As shown, when the cleaning robot is in the dust collecting state, the first switching baffle 45 is located at the first preset position, and the second switching baffle 46 is located at the third preset position. At this time, the air inlet 31 is connected to the first dust box air port 24, and the air outlet 32 ​​is connected to the atmosphere.

[0079] like Fig.13 As shown, when the cleaning robot is discharging dust in the first dust discharging method, the first switching baffle 45 is located at the second preset position, and the second switching baffle 46 is located at the third preset position. At this time, the air inlet 31 and the first dust box air port 24 are separated by the first switching baffle 45, and the air inlet 31 is connected to the dust storage chamber 82, and the air outlet 32 ​​is connected to the atmosphere.

[0080] like Fig.14 As shown, when the cleaning robot is discharging dust in the second dust discharging method, the first switching baffle 45 is located at the second preset position, and the second switching baffle 46 is located at the fourth preset position. At this time, the air inlet 31 and the first dust box air port 24 are separated by the first switching baffle 45, and the air inlet 31 is connected to the atmosphere, the air outlet 32 ​​is separated from the atmosphere by the second switching baffle 46, and the air outlet 32 ​​is connected to the dust collecting chamber 21.

[0081] like Fig.15 As shown, when the cleaning robot is discharging dust in the third dust discharging method, the first switching baffle 45 is located at the second preset position, and the second switching baffle 46 is located at the fourth preset position. At this time, the air inlet 31 and the first dust box air port 24 are separated by the first switching baffle 45, and the air inlet 31 is connected to the dust storage chamber 82, the air outlet 32 ​​is separated from the atmosphere by the second switching baffle 46, and the air outlet 32 ​​is connected to the dust collecting chamber 21.

[0082] Specifically, the first end of the first switching baffle 45 is rotatably connected to the body 10, and the second end of the first switching baffle 45 is located at the first air inlet 431. The first driving mechanism can drive the first switching baffle 45 to swing in a direction close to and away from the first dust box air outlet 24, so that the first switching baffle 45 switches between the first preset position and the second preset position; the first end of the second switching baffle 46 is rotatably connected to the body 10, and the second end of the second switching baffle 46 is located at the first air outlet 441. The second driving mechanism can drive the second switching baffle 46 to swing in a direction close to and away from the second dust box air outlet 25, so that the second switching baffle 46 switches between the third preset position and the fourth preset position.

[0083] In one embodiment of the present application, the air inlet 31 and the air outlet 32 ​​can be respectively located at two opposite ends of the fan 30, the air inlet duct is located at the end of the fan 30 having the air inlet 31, and the air outlet duct is located at the end of the fan 30 having the air outlet 32. The first dust box air inlet 24 is arranged corresponding to the air inlet duct, and the second dust box air inlet 25 is arranged corresponding to the air outlet duct. The dust outlet 23 is located between the first dust box air inlet 24 and the second dust box air inlet 25, so as to facilitate the connection between the first dust box air inlet 24 and the air inlet 31 and the air inlet duct, and also facilitate the connection between the second dust box air inlet 25 and the air outlet 32 ​​and the air outlet duct.

[0084] In some embodiments of the present application, Fig.18 As shown, a dust exhaust channel 11 may also be provided on the body 10 , a first end of the dust exhaust channel 11 is a dust outlet 23 , and when the cleaning robot is in a dust exhaust state, a second end of the dust exhaust channel 11 is connected to the dust suction port 81 .

[0085] In some embodiments of the present application, a roller brush 62 may also be installed on the body 10 , and part of the roller brush 62 is exposed from the bottom of the body 10 . When the cleaning robot performs dust collection, the roller brush 62 rotates to collect ground garbage into the dust inlet 22 .

[0086] like Figures 17 to 19As shown, in some embodiments of the present application, the cleaning robot also includes a first cover plate 71 and / or a second cover plate 72. It should be noted that the cleaning robot may be provided with only the first cover plate 71 or only the second cover plate 72, or the cleaning robot may be provided with both the first cover plate 71 and the second cover plate 72.

[0087] The first cover plate 71 is disposed in the dust collection chamber 21 and is movably connected to the dust collection box 20. When the cleaning robot is in the dust collection state, the first cover plate 71 opens the dust inlet 22; when the cleaning robot is in the dust discharge state, the first cover plate 71 closes the dust inlet 22. The opening and closing of the dust inlet 22 can be controlled by the first cover plate 71, so that when the cleaning robot is in the dust collection state, the dust inlet 22 is opened, and the garbage can smoothly enter the dust collection chamber 21 through the dust inlet 22; when the cleaning robot is in the dust discharge state, the dust inlet 22 is closed to prevent the garbage in the dust collection chamber 21 from being discharged through the dust inlet 22.

[0088] The second cover plate 72 is disposed outside the dust collecting chamber 21 and is movably connected to the dust collecting box 20. When the cleaning robot is in the dust collecting state, the second cover plate 72 closes the dust outlet 23; when the cleaning robot is in the dust discharging state, the second cover plate 72 opens the dust outlet 23. The opening and closing of the dust outlet 23 can be controlled by the second cover plate 72, so that when the cleaning robot is in the dust collecting state, the dust outlet 23 is closed to prevent garbage from entering the dust collecting chamber 21 and then being discharged through the dust outlet 23; when the cleaning robot is in the dust discharging state, the dust outlet 23 is opened so that the garbage in the dust collecting chamber 21 can be smoothly transferred to the dust storage chamber 82 through the dust outlet 23.

[0089] In one embodiment of the present application, when the cleaning robot includes a first cover plate 71, the first cover plate 71 has a first connection end 712 and a first movable end 711 arranged opposite to the first connection end 712, and the first connection end 712 is rotatably connected to the dust box 20. When the cleaning robot is in a dust collecting state, the first cover plate 71 rotates relative to the dust box 20 away from the dust inlet 22 under the action of the airflow generated by the fan 30 to open the dust inlet 22; when the cleaning robot is in a dust exhausting state, the first cover plate 71 closes the dust inlet 22.

[0090] In one embodiment of the present application, when the cleaning robot includes a second cover plate 72, the second cover plate 72 has a second connection end 722 and a second movable end 721 arranged opposite to the second connection end 722, and the second connection end 722 is rotatably connected to the dust box 20. When the cleaning robot is in a dust collection state, the second cover plate 72 closes the dust outlet 23; when the cleaning robot is in a dust discharge state, the second cover plate 72 rotates relative to the dust box 20 away from the dust outlet 23 under the action of the airflow generated by the fan 30 to open the dust outlet 23.

[0091] It should also be noted that, taking the case where the first cover plate 71 and the second cover plate 72 are provided at the same time, when the cleaning robot is in the dust collecting state, the fan 30 draws air in the dust collecting chamber 21, forming a negative pressure in the dust collecting chamber 21, so that the first cover plate 71 rotates away from the dust inlet 22 relative to the dust collecting box 20 under the action of suction to open the dust inlet 22, and the second cover plate 72 remains in contact with the outer wall of the dust collecting box 20 under the action of suction, so that the dust outlet 23 remains closed. At this time, ground garbage can smoothly enter the dust collecting chamber 21 through the dust inlet 22, and the garbage in the dust collecting chamber 21 can be prevented from being discharged through the dust outlet 23. When the cleaning robot is in the dust discharge state, the first cover plate 71 contacts the inner wall of the dust collecting chamber 21, so that the dust inlet 22 remains closed, and the second cover plate 72 rotates away from the dust outlet 23 under the suction force of the dust suction port 81 of the base station 80 or the positive pressure in the dust collecting chamber 21 to open the dust outlet 23. The garbage in the dust collecting chamber 21 can smoothly pass through the dust outlet 23 and the dust suction port 81 into the dust storage chamber 82, and the garbage in the dust collecting chamber 21 can be prevented from being discharged through the dust inlet 22.

[0092] In the second aspect, the present application further provides a cleaning robot, which includes a body 10, a dust box 20, a fan 30 and an airflow reversing mechanism 40; the dust box 20 is installed on the body 10, and the dust box 20 has a dust collecting chamber 21, a dust inlet 22 connected to the dust collecting chamber 21, a dust outlet 23 and a first dust box air port 24; the fan 30 is installed on the body 10, and the fan 30 is used to generate an airflow; the airflow reversing mechanism 40 is installed on the body 10, and the airflow reversing mechanism 40 is used to change the flow direction of the airflow generated by the fan 30;

[0093] Among them, the cleaning robot has a dust collection state and a dust exhaust state. When the cleaning robot is in the dust collection state, the airflow reversing mechanism 40 is used to make the airflow generated by the fan 30 drive the garbage into the dust collecting chamber 21 from the dust inlet 22; when the cleaning robot is in the dust exhaust state, the airflow reversing mechanism 40 is used to make the airflow generated by the fan 30 discharge the garbage in the dust collecting chamber 21 from the dust outlet 23.

[0094] It should also be noted that the cleaning robot can cooperate with the base station 80 when performing dust removal. When the cleaning robot is in the dust removal state, the garbage in the dust collecting chamber 21 can be discharged into the dust storage chamber 82 of the base station 80 through the dust discharge port; the cleaning robot can also work independently when performing dust removal without cooperating with the base station 80. For example, when the cleaning robot is in the dust removal state, the garbage in the dust collecting chamber 21 can be directly discharged into a designated area or a designated structure (not the base station 80) through the dust discharge port, and the garbage in the dust collecting chamber 21 can also be discharged into garbage containers such as garbage bags or garbage cans prepared by the user through the dust discharge port.

[0095] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
