[0002] The dust collection device generally comprises a box body, a dust bag assembly which can be taken out of the box body, and a box cover which can cover the box body. Before the dust collection device works, it is necessary to detect whether the dust bag assembly is installed in place. For this purpose, the existing dust collection device generally sets an in-place sensor to detect whether the dust bag assembly is installed in place to prevent the dust bag from not being installed in place when the dust collection device starts. However, the in-place sensor function in the current dust collection device is relatively single, and cannot detect the case that the dust bag assembly is installed in place but the box cover is not covered, which leads to the dust collection device unable to work normally and poor use performance. SUMMARY

[0009] A controller is configured to limit the dust collection device to start a dust collection action when the induction switch generates the second signal.

[0010] In a second aspect, the application also discloses a cleaning robot system, which comprises a cleaning robot and the dust collecting device described above, and the cleaning robot can automatically dock with the dust collecting device so that the dust collecting device can suck the garbage of the cleaning robot into the dust bag assembly.

[0025] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0026] Referring to Figures 1 to 7 An embodiment of the present application provides a dust collecting device 100, comprising:

[0027] A shell 10, wherein a slot 11 is arranged in the shell 10;

[0028] A cover 20, wherein the cover 20 is movably connected to the shell 10 to cover or open an inner cavity of the shell 10, and the cover 20 is provided with a trigger 21;

[0029] A dust bag assembly 30, wherein the dust bag assembly 30 is detachably installed in the shell 10, and the dust bag assembly 30 is provided with a plug plate 31, and the plug plate 31 is plug-in matched with the slot 11;

[0030] The induction switch assembly 40 comprises a movable mechanism 41 and an induction switch 42 installed on the movable mechanism 41, the movable mechanism 41 is movably connected to the shell 10 to drive the induction switch 42 to switch between a first position and a second position; the movable mechanism 41 is provided with a force receiving portion 43, the plug plate 31 can be inserted into the insertion slot 11 to press the force receiving portion 43, so as to drive the induction switch 42 to move to the first position, to allow the trigger 21 to trigger the induction switch 42 to generate a first signal when the cover 20 covers the shell 10; the plug plate 31 can be separated from the insertion slot 11 to cancel the pressing on the force receiving portion 43, so as to allow the induction switch 42 to return to the second position to generate a second signal, wherein the first signal is different from the second signal.

[0031] The controller 50 limits the dust collection device 100 to start the dust collection action when the induction switch 42 generates the second signal.

[0032] Compared with the prior art, the dust collection device 100 of the present application is provided with the force receiving portion 43 of the movable mechanism 41, the plug plate 31 can be inserted into the insertion slot 11 to press the force receiving portion 43, so as to drive the induction switch 42 to move to the first position, to allow the trigger 21 to trigger the induction switch 42 to generate a first signal when the cover 20 covers the shell 10; and the plug plate 31 can be separated from the insertion slot 11 to cancel the pressing on the force receiving portion 43, so as to allow the induction switch 42 to return to the second position to generate a second signal; the controller 50 limits the dust collection device 100 to start the dust collection action when the induction switch 42 generates the second signal, so as to realize the detection of the simultaneous presence of the cover 20 and the dust bag assembly 30, and avoid the situation that the dust collection device 100 still starts the dust collection action when the dust bag assembly 30 is installed in place but the cover is not closed or tightly closed.

[0033] First of all, it needs to be pointed out that when the dust collection device 100 performs the dust collection action, the plug plate 31 of the dust bag assembly 30 is inserted into the insertion slot 11 in the shell 10, and the cover 20 covers the box body, at this time, dust and other impurities can be introduced into the dust bag assembly 30 under the vacuum negative pressure of the dust extraction fan 15; when the dust collection device 100 suspends the dust collection action, the operator can open the cover 20 to take out the dust bag assembly 30 from the shell 10, and can put a new dust bag assembly 30 back into the box body for the dust collection device 100 to work.

[0034] In the embodiment, the controller 50 is electrically connected to the induction switch assembly 40. The controller 50 restricts the dust collection device 100 from performing the dust collection action according to the non-triggered state of the induction switch assembly 40. The controller 50 releases the restriction on the dust collection device 100 from performing the dust collection action according to the triggered state of the induction switch assembly 40.

[0035] Optionally, the controller 50 can be a microcontroller unit (MCU). For example, the controller 50 can be an ARM Cortex-M4-32-bit microcontroller. The present embodiment is not limited in this regard.

[0036] Therefore, before the dust collection device 100 performs the dust collection action, the present embodiment detects whether the dust bag assembly 30 is in place (i.e., whether the plug plate 31 of the dust bag assembly 30 is plugged into the slot 11 in the housing 10) and whether the cover 20 covers the housing 10 by using the induction switch assembly 40, and feeds the detection results to the controller 50. The controller 50 then restricts or releases the restriction on the operation of the dust collection device 100. This can achieve a single sensor dual detection function, which is beneficial for saving the number of sensors, reducing costs, and having a simple structure and high reliability.

[0037] In the embodiment, the housing 10 is the main part of the dust collection device 100. The housing 10 is provided with a dust collection port 12, a dust inlet channel 13, an inner cavity, and an exhaust channel 14. The dust collection port 12 is arranged on the outer side of the housing 10 and is used to be connected to the dust outlet of the cleaning robot 200. The inner cavity is used to accommodate the dust bag assembly 30. The inner cavity has an open end, and the dust bag assembly 30 is detachably installed in the inner cavity of the housing 10 through the open end. The cover 20 is rotationally connected to the housing 10 to cover or open the open end of the inner cavity. One end of the dust inlet channel 13 is connected to the dust collection port 12, and the other end is connected to the inner cavity. One end of the exhaust channel 14 is connected to the dust collection cavity, and the other end is connected to the atmosphere. The dust bag assembly 30 is installed in the dust collection cavity and can be connected to the dust inlet channel 13 and the exhaust channel 14. The dust extraction fan 15 is located in the exhaust channel 14. The dust extraction fan 15 is used to drive the flow of gas. The dust extraction fan 15 can drive the gas in the inner cavity to flow to the exhaust channel 14 to be discharged to the outside, so as to generate a negative pressure in the dust bag assembly 30 and the dust inlet channel 13, thereby sucking the garbage in the cleaning robot 200 to the dust bag assembly 30 under the action of the negative pressure, and thus achieving the dust collection action.

[0038] In the embodiment, the dust bag assembly 30 comprises a bag body 32 and a plug plate 31 connected to the bag body 32. The plug plate 31 is provided with an opening 312 communicating with the inside of the bag body 32. When the plug plate 31 of the dust bag assembly 30 is plugged into the slot 11 in the shell 10, the opening 312 is butted against the port of the dust inlet channel 13, so that the dust inlet channel 13 is in communication with the dust bag assembly 30. The bag body 32 is a filter bag. When the dust extraction fan 15 is in operation, the dust inlet channel 13 can guide air flow to the bag body 32 under the action of vacuum negative pressure, and then the air flow can pass through the bag body 32 and enter the air outlet channel 14 to be discharged, wherein the bag body 32 can play a filtering role to intercept dust and debris carried in the air flow. The material of the bag body 32 can be plastic, paper or composite material, which is not specifically limited here, and can be set according to actual needs by those skilled in the art.

[0039] In the embodiment, the plug plate 31 can be plugged into the slot 11 to press the stress part 43, so as to drive the induction switch 42 to move to the first position, to allow the trigger 21 to trigger the induction switch 42 to generate a first signal when the cover 20 covers the shell 10. The first position corresponds to the position of the trigger 21 relative to the cover 20. The plug plate 31 can be separated from the slot 11 to cancel the pressing on the stress part 43, so as to allow the induction switch 42 to return to the second position to generate a second signal, wherein the first signal is different from the second signal, and the first signal is used to indicate that the dust bag assembly 30 is installed in place and the cover 20 covers the shell 10.

[0040] In the embodiment, the movable mechanism 41 is movably connected to the shell 10. The dust bag assembly 30 is installed in the shell 10 to push the movable mechanism 41 to a first preset position through the plug plate 31, so as to drive the induction switch 42 to move to the first position. The dust bag assembly 30 is detached from the shell 10 to cancel the pushing, so that the movable mechanism 41 automatically returns to a second preset position under the action of the elastic element 412, to drive the induction switch 42 to move to the second position. When the induction switch 42 is in the first position, the trigger 21 can move close to the first position when the cover 20 is closed on the shell 10, to trigger the induction switch 42. When the induction switch assembly 40 is in the second position, the trigger 21 can move close to the first position when the cover 20 is closed on the shell 10, and the trigger 21 is finally arranged away from the induction switch 42, so that the trigger 21 cannot trigger the induction switch 42 in the second position.

[0041] The movable mechanism 41 comprises a movable support 411 movably connected to the shell 10 and an elastic element 412 elastically connecting the movable support 411 and the shell 10, the elastic element 412 being configured to provide an elastic force for driving the movable support 411 to drive the inductive switch 42 to return to the second position, the movable support 411 being provided with the force receiving portion 43 and a bearing portion 44 opposite to the force receiving portion 43, and the inductive switch 42 being mounted on the bearing portion 44.

[0042] The movable support 411 is slidably connected to the shell 10. Alternatively, the movable support 411 is rotatably connected to the shell 10.

[0043] In some embodiments, the movable support 411 is slidably connected to the shell 10, the movable mechanism 41 is arranged to move along a straight line, and the moving direction of the movable mechanism 41 is perpendicular to the moving direction of the plug-in board 31. In this case, the moving direction of the movable mechanism 41 is along the horizontal direction, i.e. the movable mechanism 41 can move horizontally left and right, the force receiving portion 43 can move horizontally left and right, and the inductive switch 42 can move horizontally left and right along with the movable mechanism 41. The plug-in board 31 is arranged to move along the vertical direction.

[0044] In some embodiments, the movable mechanism 41 is rotatably connected to the shell 10, and the rotation axis of the movable mechanism 41 is perpendicular to the plug-in board 31. In this case, the shell 10 is provided with a matching surface 15 located on one side of the insertion slot 11. When the plug-in board 31 is inserted into the insertion slot 11, the plug-in board 31 is arranged to abut against the matching surface 15. The rotation axis of the movable mechanism 41 is perpendicular to the matching surface 15, so that the rotation plane of the movable mechanism 41 is arranged to be substantially parallel to the matching surface 15. When the plug-in board 31 presses the force receiving portion 43, the bearing portion 44 moves towards the side close to the cover 20, so as to finally drive the inductive switch 42 to move to the first position. When the plug-in board 31 is separated from the force receiving portion 43, the bearing portion 44 moves away from the side close to the cover 20, so as to finally drive the inductive switch 42 to move to the second position.

[0045] In some embodiments, the movable mechanism 41 is rotatably connected to the shell 10, and the rotation axis of the movable mechanism 41 is parallel to the plug plate 31. The shell 10 is provided with a matching surface 15 on one side of the plug slot 11. The plug plate 31 is inserted into the plug slot 11 and is in abutment with the matching surface 15. The rotation axis of the movable mechanism 41 is parallel to the matching surface 15, so that the rotation plane of the movable mechanism 41 is perpendicular to the matching surface 15. When the plug plate 31 presses the stress part 43, the bearing part 44 moves towards the side close to the cover 20, so as to finally drive the induction switch 42 to move to the first position. When the plug plate 31 is separated from the stress part 43, the bearing part 44 moves away from the side close to the cover 20, so as to finally drive the induction switch 42 to move to the second position.

[0046] In some embodiments, the induction switch 42 is a photoelectric switch, and the trigger 21 is a light-blocking part arranged on the surface of the cover 20. Alternatively, the induction switch 42 is a Hall switch, and the trigger 21 is a magnetic element. The induction switch 42 is a touch switch, and the trigger 21 is a protruding part arranged on the surface of the cover 20.

[0047] In some embodiments, the induction switch 42 is a photoelectric switch, and the trigger 21 is a light-blocking part arranged on the surface of the cover 20. The induction switch 42 includes a transmitter and a receiver arranged opposite to the transmitter, and a gap is arranged between the transmitter and the receiver. The transmitter emits light signals to the receiver through the gap. The trigger 21 can extend into the gap when the cover 20 is closed on the shell 10, and the trigger 21 can block the light signals, so that the induction switch 42 generates a first signal. The trigger 21 can be separated from the gap when the cover 20 is opened relative to the shell 10, and the receiver can receive the light signals of the transmitter through the gap, so that the induction switch 42 generates a second signal.

[0048] In some embodiments, the induction switch 42 is a Hall switch, and the trigger 21 is a magnetic element. The trigger 21 can be adjacent to the induction switch 42 when the cover 20 is closed on the shell 10, and the induction switch 42 can be triggered by the magnetic field strength of the trigger 21 to generate a first signal. The trigger 21 is away from the induction switch 42 when the cover 20 is opened relative to the shell 10, and the induction switch 42 is in a non-triggered state to generate a second signal.

[0049] In some embodiments, the sensing switch 42 is a microswitch, and the trigger 21 is a protrusion arranged on the surface of the cover 20. When the cover 20 is closed on the shell 10, the trigger 21 can touch the sensing switch 42, so that the sensing switch 42 is triggered to generate a first signal. When the cover 20 is opened relative to the shell 10, the trigger 21 can move away from the sensing switch 42, so that the sensing switch 42 is not triggered to generate a second signal.

[0050] Please refer to Figures 1 to 9 Further, the force receiving part 43 is movably arranged in the slot 11, and the insertion plate 31 can press the force receiving part 43 through the side edge 311. The force receiving part 43 is substantially hidden in the slot 11, so that the shell 10 does not need to be opened on the front side. This is advantageous for reducing the number of openings exposed on the front side of the shell 10, reducing the situation that the openings are blocked by dust, and also reducing the risk that the force receiving part 43 is interfered by garbage particles to move. The risk of damage to the force receiving part 43 is low.

[0051] In the embodiment, the shell 10 is provided with a first cavity 16 and a second cavity 17, and a separation support 18 separates the first cavity 16 and the second cavity 17. The first cavity 16 is used to accommodate the dust bag assembly 30, and the second cavity 17 is used to accommodate the sensing switch assembly 40. The separation support 18 is provided with the slot 11 near one side of the first cavity 16. The separation support 18 is provided with an opening 19 at the side wall corresponding to the slot 11, and the force receiving part 43 extends into the slot 11 through the opening 19.

[0052] The volume of the first cavity 16 is greater than the volume of the second cavity 17, so that the first cavity 16 can provide a larger volume for accommodating the dust bag assembly 30. The first cavity 16 has an open end, through which a user can place the dust bag assembly 30 into the first cavity 16. The cover 20 can cover the open end when the cover 20 is closed on the shell 10. The separation support 18 can be fixed in the shell 10 by screw connection, one-piece injection molding, heat welding, or glue bonding. The first cavity 16 may, unavoidably, have dust residues due to dust collection. The separation support 18 separates the first cavity 16 and the second cavity 17, so that the first cavity 16 and the second cavity 17 are independent of each other. This avoids dust and debris in the first cavity 16 from invading the second cavity 17 and being difficult to clean. Furthermore, this avoids the sensing switch 42 and the movable mechanism 41 in the second cavity 17 from being interfered by dust and debris to work abnormally. For example, the movable mechanism 41 can be hindered by dust and debris to increase the moving resistance, so as to ensure the reliability and service life of the sensing switch assembly 40.

[0053] Since the opening 19 is arranged on the side wall of the slot 11 corresponding to the isolation support 18, the opening 19 is hidden inside the slot 11, and the plug-in plate 31 is inserted into the slot 11 to cover the opening 19, so that the number of exposed openings on the isolation support 18 can be reduced, the first cavity 16 and the second cavity 17 can be isolated from each other, dust and debris in the first cavity 16 cannot enter the second cavity 17 and cannot be cleaned, and the induction switch 42 and the movable mechanism 41 in the second cavity 17 cannot be disturbed by dust and debris and cannot work normally, so that the reliability and service life of the induction switch assembly 40 can be ensured. Moreover, the isolation degree of the first cavity 16 and the second cavity 17 is high, and when the dust collection device 100 generates a vacuum suction effect on the first cavity 16, a negative pressure suction effect on the second cavity 17 can be avoided, and the induction switch assembly 40 can be avoided from being damaged due to the negative pressure suction effect.

[0054] The main body of the movable support 411 is accommodated in the first cavity 16, and the stress receiving portion 43 of the movable support 411 extends into the slot 11 through the opening 19, so that the stress receiving portion 43 can be movably arranged in the slot 11. The plug-in plate 31 has two opposite side edges 311, and the two side edges 311 are parallel to the extension direction of the slot 11. In this embodiment, the plug-in plate 31 presses the stress receiving portion 43 through one of the two side edges 311 to drive the movable mechanism 41 to move laterally as a whole, so as to drive the induction switch 42 to move to the first position.

[0055] Please continue to refer to Figure 7 In some embodiments, the isolation support 18 is provided with an opening 181 corresponding to the first position, and the trigger 21 extends into the opening 181 when the cover 20 covers the shell 10 to trigger the induction switch 42. Since the trigger 21 is protrudingly arranged on the surface of the cover 20, the trigger 21 can extend into the opening 181 to be close enough to the induction switch 42, so as to facilitate sensitive triggering of the induction switch 42.

[0056] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 9Further, the slot 11 has an open notch 111, the plug plate 31 is inserted into the slot 11 through the notch 111, the force receiving part 43 has a force receiving surface 431 facing the side where the notch 111 is located, the force receiving surface 431 is arranged obliquely relative to the length direction of the slot 11, and the plug plate 31 pushes the movable mechanism 41 to move laterally through the force receiving surface 431. The notch 111 faces the open end of the first cavity 16. The force receiving surface 431 can be an oblique plane or a curved surface. When the plug plate 31 is inserted into the slot 11 along the vertical direction, the plug plate 31 can generate a horizontal pushing force on the movable mechanism 41 through the force receiving surface 431, so as to drive the movable mechanism 41 to move laterally as a whole, and drive the induction switch 42 to move to the first position.

[0057] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 9 Further, the shell 10 is provided with two slots 11 arranged oppositely, the two side edges 311 of the plug plate 31 are respectively inserted into the two slots 11, and the two slots 11, the plug plate 31 and the force receiving part 43 are located on the same plane. The shell 10 is further provided with a matching surface 15 located between the two slots 11. When the two side edges 311 of the plug plate 31 are respectively inserted into the two slots 11, the plug plate 31 is arranged in close contact with the matching surface 15, and the two slots 11 and the matching surface 15 have the function of fixing and limiting the plug plate 31, so that the plug plate 31 can move along the length direction of the slot 11 without left-right deviation, and the plug plate 31 is convenient to press against the force receiving part 43 along the vertical direction. Since the two slots 11, the plug plate 31 and the force receiving part 43 are located on the same plane, the reverse pushing force of the force receiving part 43 on the plug plate 31 will not affect the close contact degree of the plug plate 31 and the matching surface 15, and the sealing performance is guaranteed. The matching surface 15 is provided with a dust conveying port, the plug plate 31 is provided with a dust inlet port communicating with the inner cavity of the bag body 32, the plug plate 31 is arranged in close contact with the matching surface 15, and the dust conveying port and the dust inlet port are connected, so as to guide the dust and debris into the bag body 32. In other embodiments, the two slots 11, the plug plate 31 and the force receiving part 43 can not be located on the same plane.

[0058] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 9Further, the two slots 11 include a first slot 112 and a second slot 113, the force receiving portion 43 is elastically movably arranged in the first slot 112 in a direction close to or away from the second slot 113, and when the plug-in board 31 is plugged into the two slots 11, the force receiving portion 43 generates a resisting force on the side edge 311 of the plug-in board 31 in a direction pointing to the second slot 113. In the embodiment, the movable support 411 is in sliding connection with the shell 10, and the sliding direction of the movable support 411 relative to the shell 10 is perpendicular to the extension direction of the two slots 11, so that the force receiving portion 43 can be elastically movably arranged in the first slot 112 in a direction close to or away from the second slot 113.
