[0001] The present invention relates to the technical field of cleaning robots, and in particular to a dust collecting device and a cleaning robot system. Background Art

[0002] The dust collecting device is a device for collecting dust and other foreign matter, and is generally used in cleaning robots. At present, the dust collecting device generally includes a dust collecting bucket, a shell and a cover body. The cover body is closed on the shell to generate a mechanical trigger, thereby controlling the operation of the dust collecting bucket. This dust collecting device has the following defects: 1. The resistance encountered when the cover body is closed on the shell is large. After repeated use, the cover body may not be closed on the shell, causing product damage or failure, affecting the service life of the product; 2. After repeated use, the mechanical trigger structure between the cover body and the shell will accumulate a lot of dust and foreign matter. The dust and foreign matter will affect the function or sensitivity of the mechanical trigger, affect the normal use of the product, and affect the service life of the product; 3. Some mounting holes need to be set to install the mechanical trigger structure, which will affect the firmness and overall aesthetics of the product. Summary of the invention

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0029] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figure 1 to Figure 2 , a dust collecting device 200, comprising:

[0031] Housing 10;

[0032] A dust bag assembly 20, wherein the dust bag assembly 20 is detachably installed in the housing 10;

[0033] A cover body 30, the cover body 30 is used to cover the housing 10;

[0034] A non-contact induction switch assembly 40 is mounted on the housing 10;

[0035] A non-contact trigger 50 is installed on the cover 30;

[0036] A controller (not shown), electrically connected to the non-contact induction switch assembly 40;

[0037] When the dust bag assembly 20 is installed in the housing 10 and the cover 30 is covered on the housing 10, the non-contact trigger member 50 can move with the cover 30 to a position close to the non-contact sensing switch assembly 40, so that the non-contact sensing switch assembly 40 generates a trigger signal;

[0038] When the dust bag assembly 20 is detached from the housing 10, or / and the cover 30 is opened relative to the housing 10, the non-contact induction switch assembly 40 does not generate a trigger signal;

[0039] When the controller determines that the non-contact induction switch assembly 40 does not generate a trigger signal, the dust collecting device 200 is restricted from starting the dust collecting action.

[0040] First of all, it should be explained that when the dust collecting device is performing dust collecting action, the plug plate of the dust bag assembly is inserted into the slot in the shell, and the cover body covers the box body. At this time, dust and other impurities can be introduced into the dust bag assembly through the dust inlet channel under the vacuum negative pressure of the dust extraction fan; and when the dust collecting device suspends the dust collection action, the operator can open the cover body to remove the dust bag assembly from the shell, and then put a new dust bag assembly back into the box body, waiting for the dust collecting device to work.

[0041] In this embodiment, the dust bag assembly includes a bag body and a plug plate connected to the bag body. The plug plate is provided with an opening connected to the inside of the bag body. When the plug plate of the dust bag assembly is plugged into the slot in the shell, the opening docks with the port of the dust inlet channel, so that the dust inlet channel is connected to the dust bag assembly. The bag body is a filter bag. When the dust extraction fan is working, the dust inlet channel can introduce airflow into the bag body under the action of vacuum negative pressure, and then the airflow can pass through the bag body and enter the exhaust channel and be discharged, wherein the bag body can play a filtering role and intercept dust debris carried in the airflow. The material of the bag body can be plastic, paper or a composite material, which is not specifically limited here, and those skilled in the art can set it according to actual needs.

[0042] In this embodiment, the controller is electrically connected to the induction switch assembly. The controller limits the dust collection device from performing dust collection according to the untriggered state of the induction switch assembly. The controller releases the restriction on the dust collection device from starting the dust collection according to the triggered state of the induction switch assembly.

[0043] Optionally, the controller may be a microcontroller unit (MCU), for example, the controller may be an ARM Cortex-M4-32-bit microcontroller, which is not limited in this embodiment.

[0044] Therefore, before the dust collecting device performs dust collecting, this embodiment uses a non-contact sensing switch assembly to detect whether the dust bag assembly is in place (i.e., whether the plug plate of the dust bag assembly is plugged into the slot in the shell) and whether the cover body covers the shell, and feeds back the detection result to the controller, which then limits or releases the limit on the operation of the dust collecting device. This can achieve dual detection functions of a single sensor, which is beneficial to saving the number of sensors, reducing costs, having a simple structure and high reliability.

[0045] By adopting a non-contact sensing control method instead of a mechanical touch method, the resistance when the cover 30 is closed is eliminated, dust can be prevented from obstructing the movement of the mechanical structure, and the cover 30 can be prevented from being difficult to close. The number of holes and grooves on the shell 10 and the cover 30 is reduced, and the product appearance is more complete.

[0046] Please refer to Figure 3 In this embodiment, the housing 10 is the main body of the dust collecting device 200, and the housing 10 is provided with a dust collecting port 12, a dust inlet channel 13, an inner cavity and an exhaust channel 14. The dust collecting port 12 is arranged on the outside of the housing 10, and the dust collecting port 12 is used to dock with the dust exhaust port of the cleaning robot 100. The inner cavity is used to accommodate the dust bag assembly 30, and the inner cavity has an open end. The dust bag assembly 30 can be detachably installed in the inner cavity of the housing 10 through the open end. The cover body 20 is rotatably 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 collecting port 12, and the other end is connected to the inner cavity. One end of the exhaust channel 14 is connected to the dust collecting cavity, and the other end is connected to the atmosphere. The dust bag assembly 30 is installed in the dust collecting 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, and is used to drive the gas flow. 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 negative pressure in the dust bag assembly 30 and the dust inlet channel 13, so as to achieve dust collection by sucking the garbage in the cleaning robot 100 into the dust bag assembly 30 under the action of negative pressure.

[0047] In one embodiment, the non-contact induction switch assembly 40 includes a movable mechanism 42, a barrier 44 and a non-contact induction switch 46, one of the barrier 44 and the non-contact induction switch 46 is fixedly connected to the movable mechanism 42, and the other of the barrier 44 and the non-contact induction switch 46 is fixedly connected to the housing 10, so that the movable mechanism 42 can drive one of the barrier 44 and the non-contact induction switch 46 to move relative to the housing 10;

[0048] When the dust bag assembly 20 is installed in the housing 10 and the cover 30 is covered on the housing 10, the blocking member 44 is in a position where it does not block the non-contact trigger member 50 and the non-contact induction switch 46, so as to allow the non-contact induction switch assembly 40 to generate a trigger signal;

[0049] When the dust bag assembly 20 is detached from the housing 10 and the cover 30 is covered on the housing 10, the blocking member 44 is located between the non-contact trigger member 50 and the non-contact sensing switch 46 to prevent the non-contact sensing switch assembly 40 from generating a trigger signal.

[0050] When the dust bag assembly 20 is installed in the housing 10 and the cover 30 is not covered on the housing 10, the distance between the non-contact trigger 50 and the non-contact sensing switch 46 is too far, and the non-contact trigger 50 will not trigger the non-contact sensing switch 46 to generate a trigger signal.

[0051] Specifically, in one embodiment, the non-contact induction switch 46 is a Hall switch, and the non-contact trigger 50 is a magnetic member. The non-contact induction switch 46 can also be an infrared induction switch, and the non-contact trigger 50 is a structure that can trigger the infrared induction switch. In this embodiment, the non-contact induction switch 46 is a Hall switch, the non-contact trigger 50 is a magnetic member, and the barrier 44 is a magnetic isolation sheet as an example for explanation. When the dust bag assembly 20 is installed in the housing 10, and the cover body 30 is covered on the housing 10, the barrier 44 or the non-contact induction switch 46 is driven to move by the movable mechanism 42. When the barrier 44 is in a position where it does not block the non-contact trigger 50 and the non-contact induction switch 46, the non-contact induction switch assembly 40 can generate a trigger signal, and the controller controls the dust bag assembly 20 to work. For example, the Hall switch is affected by the strength of the magnetic field, and the output voltage of the Hall switch will change. Under normal circumstances, when the Hall switch is not affected by a magnetic field of sufficient strength, the output voltage is 3.3V, otherwise it outputs 0V; and the movable mechanism 42 of this embodiment determines whether to drive the blocking member 44 to move by whether the dust bag assembly 20 is inserted and whether the cover body 30 is closed, so as to associate with the change of the Hall switch voltage, thereby controlling whether the dust bag assembly 20 can enter the working state.

[0052] In one embodiment, the movable mechanism 42 is movably connected to the housing 10, and the dust bag assembly 20 is installed in the housing 10 to push the movable mechanism 42 to the first position, so that the blocking member 44 and the non-contact induction switch 46 are staggered.

[0053] The dust bag assembly 20 is detached from the housing 10 and the push is canceled so that the movable mechanism 42 automatically returns to the second position under the action of the elastic element 424, so that the blocking member 44 blocks the non-contact sensing switch 46. The movable mechanism 42 is in the first position or the second position according to whether the dust bag assembly 20 is installed in the housing 10.

[0054] Please refer to Figures 4 to 6 In one embodiment, the housing 10 is provided with a slot 12, and the movable mechanism 42 is provided with a force-bearing portion 426. When the movable mechanism 42 is located at the second position, the force-bearing portion 426 at least partially extends into the slot 12; the dust bag assembly 20 is provided with a plug plate 22, and the plug plate 22 can be movably inserted into the slot 12 to push the movable mechanism 42 to move to the first position as a whole through the force-bearing portion 426. When the dust bag assembly 20 is installed in the housing 10, the plug plate 22 is inserted into the slot 12. During the plug plate 22 is inserted into the slot 12, the force-bearing portion 426 can be pushed to move, so that the movable mechanism 42 moves from the second position to the first position. When the movable mechanism 42 is located at the first position, the blocking member 44 and the non-contact induction switch 46 are staggered. When the cover body 30 is also covered on the housing 10, the blocking member 44 will not block the non-contact trigger member 50 and the non-contact induction switch 46, and the non-contact induction switch 46 will generate a trigger signal. When the dust bag assembly 20 is not installed in the housing 10, the movable mechanism 42 is located in the second position. At this time, no matter whether the cover body 30 is covered on the housing 10, the non-contact induction switch 46 will not generate a trigger signal. At this time, at least part of the force-bearing portion 426 extends into the slot 12. If the dust bag assembly 20 is installed in the housing 10, the plug plate 22 can push the part of the force-bearing portion 426 located in the slot 12 to move the movable mechanism 42. The dust bag assembly 20 triggers the force-bearing portion 426 through the plug plate 22, and finally controls the non-contact induction switch 46 to send a trigger signal. There is no need to set up an additional control structure. It can be automatically controlled according to whether the dust bag assembly 20 is installed. The resistance to the closing of the cover body 30 will not increase, and the cover body 30 and the housing 10 will not be difficult to close. The plug plate 22 and the force-bearing portion 426 will not be affected by accumulated dust, and the trigger function is stable and reliable.

[0055] Please refer to Figures 6 to 10In one embodiment, the housing 10 is provided with a first cavity 14 and a second cavity 16, and an isolation bracket 146 separating the first cavity 14 and the second cavity 16. The first cavity 14 is used to accommodate the dust bag assembly 20, and the second cavity 16 is used to accommodate the non-contact induction switch assembly 40. The isolation bracket 146 is provided with the slot 12 on one side close to the first cavity 14. The isolation bracket 146 is provided with an opening 1462 at the side wall corresponding to the slot 12, and the force-bearing portion 426 extends into the slot 12 through the opening 1462. The isolation bracket 146 separates the first cavity 14 and the second cavity 16, so that the dust bag assembly 20 and the non-contact induction switch assembly 40 can be independent of each other, do not interfere with each other, and avoid errors. Specifically, the force-bearing portion 426 is a wedge-shaped block, and part of the wedge-shaped block passes through the opening 1462. When the dust bag assembly 20 is installed in the first cavity 14, the dust bag assembly 20 squeezes the wedge-shaped block to move the wedge-shaped block from the opening 1462 toward the second cavity 16, thereby driving the movable mechanism 42 to move from the second position to the first position.

[0056] In one embodiment, the opening 1462 is hidden inside the slot 12 , and the opening 1462 is more concealed, which can prevent the dust bag assembly 20 and the plug board 22 from wearing it, but the force-bearing portion 426 is located at the opening 1462 , which will not affect the triggering function of the plug board 22 on the force-bearing portion 426 .

[0057] Please refer to Figures 6 to 10In one embodiment, the movable mechanism 42 includes a movable bracket 422 and an elastic element 424, the movable bracket 422 is movably connected to the shell 10, and the elastic element 424 elastically connects the movable bracket 422 and the shell 10 to provide an elastic force for the movable bracket 422 to automatically return to the second position, the movable bracket 422 is provided with the force-bearing portion 426 and a bearing portion 428 arranged relative to the force-bearing portion 426, and the blocking member 44 or the non-contact sensing switch 46 is arranged on the bearing portion 428. When the dust bag assembly 20 is not installed in the first cavity 14 of the shell 10, the movable bracket 422 is in the second position under the elastic force of the elastic element 424. When the dust bag assembly 20 is installed in the first cavity 14 of the shell 10, the plug plate 22 of the dust bag assembly 20 can push the force-bearing part 426, so that the movable bracket 422 compresses the elastic element 424, so that the movable bracket 422 is located in the first position, wherein the bearing part 428 is used to install the barrier 44 or the non-contact induction switch 46. The elastic element 424 has the function of resetting and placing the movable bracket 422 in the second position, and does not require manual operation, which is convenient for operation and control. Specifically, the elastic element 424 is a spring, which is arranged between the movable bracket 422 and the side wall of the second cavity 16. Further, one end of the spring is fixed on a side wall of the second cavity 16 close to the first cavity 14, and the other end of the spring is connected to the movable bracket 422.

[0058] Please refer to Figures 6 to 10 In one embodiment, the housing 10 is provided with two slots 12 arranged opposite to each other, and a positioning surface 122 located between the two slots 12. When the plug board 22 is plugged into and matched with the two slots 12, it is arranged to fit the positioning surface 122, and the movable track of the movable bracket 422 is arranged parallel to the positioning surface 122. The two ends of the plug board 22 fit with the two slots 12, and the board surface of the plug board 22 fits with the positioning surface 122. The two slots 12 and the positioning surface 122 have a fixing and limiting effect on the plug board 22, so that the plug board 22 can move along the length direction of the slot 12 without offset.

[0059] Please refer to Figures 6 to 10In one embodiment, the movable bracket 422 is movably arranged along a straight track, and the movable direction of the movable bracket 422 is arranged perpendicular to the length direction of the two slots 12, that is, the movable bracket 422 can move laterally relative to the shell 10, thereby driving the blocking member 44 to move laterally relative to the shell 10. When the cover body 30 is covered on the shell 10 and the movable bracket 422 is in the first position, the blocking member 44 will not be blocked between the non-contact trigger member 50 and the non-contact sensing switch 46; or, the movable bracket 422 is rotatably connected to the shell 10, and the rotation axis of the movable bracket 422 is arranged perpendicular to the positioning surface 122. Specifically, when the cover body 30 is closed on the shell 10, and when the dust bag assembly 20 is placed in the first cavity 14 of the shell 10, the plug plate 22 on the dust bag assembly 20 can push the force-bearing part 426 to rotate, thereby driving the movable bracket 422 to rotate, so that the movable bracket 422 is located in the first position, and the blocking member 44 will not be blocked between the non-contact trigger member 50 and the non-contact sensing switch 46. The movable bracket 422 is easy to control and has a simple structure.

[0060] Please refer to Figures 6 to 10 In one embodiment, when the plug plate 22 is plugged into the slot 12, the plug plate 22 presses the force-bearing portion 426 of the movable bracket 422 through the side edge, and the plug plate 22 and the force-bearing portion 426 are located in the same plane, and the plug plate 22 and the force-bearing portion 426 are not offset. In this way, when the dust bag assembly 20 is installed in the first cavity 14 of the shell 10, it can ensure that the plug plate 22 triggers the force-bearing portion 426 in a timely and accurate manner, and there will be no triggering errors.

[0061] Please refer to Figures 6 to 10 In one embodiment, the slot 12 has an open notch 124, the plug board 22 is inserted into the slot 12 through the notch 124, the force-bearing portion 426 has a force-bearing surface 4262 facing the side where the notch 124 is located, the force-bearing surface 4262 is inclined relative to the lateral movement direction of the movable mechanism 42, and the plug board 22 pushes the movable mechanism 42 to move laterally through the force-bearing surface 4262. The notch 124 has a guiding function, and the plug board 22 can quickly and accurately enter the slot 12 through the notch 124. Through the inclined force-bearing surface 4262, when the plug board 22 contacts the force-bearing surface 4262, it can ensure that the force-bearing portion 426 is pushed by the plug board 22, wherein the inclined force-bearing surface 4262 also has a buffering function, which can avoid excessive collision when the plug board 22 and the force-bearing portion 426 contact. Specifically, when the force-bearing portion is a wedge block, the force-bearing surface 4262 is an inclined surface on the wedge block.

[0062] Please refer to Figures 6 to 10In one embodiment, the housing 10 is provided with a top surface 18, and the top surface 18 is arranged adjacent to the cover 30. The non-contact induction switch 46 is fixedly connected to the housing 10 and is located on the side of the top surface 18 away from the cover 30. A gap is arranged between the non-contact induction switch 46 and the top surface 18. The blocking member 44 is fixedly connected to the movable bracket 422. When the blocking member 44 moves to the gap with the movement of the movable mechanism 42, the blocking member 44 blocks the non-contact induction switch 46. By setting the gap, it can be ensured that when the blocking member 44 moves between the non-contact induction switch 46 and the non-contact trigger member 50, there will be no interference or disturbance. When the cover 30 is covered on the housing 10, the cover 30 will not affect or damage the non-contact induction switch 46 and the non-contact trigger member 50.

[0063] Please refer to Figures 6 to 10 In one embodiment, the housing 10 is provided with a top surface 18, and the top surface 18 is disposed adjacent to the cover 30. The barrier 44 is fixedly connected to the housing 10 and is located on the side of the top surface 18 away from the cover 30. The non-contact induction switch 46 is fixedly connected to the movable bracket 422. When the non-contact induction switch 46 moves to the side of the barrier 44 away from the top surface 18 along with the movement of the movable mechanism 42, the barrier 44 blocks the non-contact induction switch 46. The non-contact trigger 50 can also be fixedly connected to the movable bracket 422, and the non-contact induction switch 46 can be installed on the cover 30 to achieve the same function, which is convenient for maintenance and use in various application scenarios.

[0064] If the distance between the non-contact induction switch 46 and the non-contact trigger member 50 is too far, the non-contact trigger member 50 is not easy to trigger the non-contact induction switch 46, and it is not easy to generate a trigger signal; if the non-contact induction switch 46 and the non-contact trigger member 50 are too close, the barrier member 44 may fail, or may interfere with or interfere with the barrier member 44. Therefore, in one embodiment, when the cover 30 is covered on the housing 10, the distance between the non-contact induction switch 46 and the non-contact trigger member 50 is 5mm to 30mm. When the distance between the non-contact induction switch 46 and the non-contact trigger member 50 is 15mm, the sensing effect is the best, and no interference or interference will occur.

[0065] Based on the combination of the above embodiments, in one embodiment, the non-contact trigger member 50 is a circular magnetic block, the non-contact sensing switch 46 is a Hall switch, the barrier 44 is a magnetic isolation sheet, the movable bracket 422 can move laterally relative to the shell 10, and the initial position of the movable bracket 422 is the second position.

[0066] When the dust bag assembly 20 is placed in the first cavity 14 of the shell 10, but the cover body 30 is not covered on the shell 10, the dust bag assembly 20 will push the inclined force surface 4262 on the force-bearing part 426 to move the movable bracket 422 from the second position to the first position. At this time, since the cover body 30 is not covered on the shell 10, although the movable bracket 422 drives the magnetic isolation plate to be in the first position, the circular magnetic block is too far away from the Hall switch, and the magnetic field of the circular magnetic block cannot affect the Hall switch, the voltage of the Hall switch will not change, and the dust bag assembly 20 will not work. Figure 2 This is a state diagram of the dust collecting device 200 when the dust bag assembly 20 is placed in the first cavity 14 of the housing 10 .

[0067] When the dust bag assembly 20 is not placed in the first cavity 14 of the shell 10, but the cover body 30 is closed on the shell 10, although the circular magnet is close to the Hall switch at this time, since the movable bracket 422 is not triggered, the movable bracket 422 is still in the second position. At this time, the magnetic isolation sheet can isolate the magnetic field of the circular magnet, and the magnetic field of the circular magnet still cannot affect the Hall switch, the voltage of the Hall switch will not change, and the dust bag assembly 20 will not work. Figure 3 This is a state diagram of the dust collecting device 200 when the dust bag assembly 20 is not placed in the first cavity 14 of the housing 10 .

[0068] When the dust bag assembly 20 is not placed in the first cavity 14 of the shell 10 and the cover 30 is not closed on the shell 10, the movable bracket 422 is not triggered, the movable bracket 422 is still in the second position, the magnetic field of the circular magnetic block still cannot affect the Hall switch, the voltage of the Hall switch will not change, and the dust bag assembly 20 will not work.

[0069] When the dust bag assembly 20 is placed in the first cavity 14 of the shell 10, and the cover 30 is also covered on the shell 10, the dust bag assembly 20 will push the inclined force surface 4262 on the force-bearing part 426, so that the movable bracket 422 moves from the second position to the first position, and the magnetic field of the circular magnetic block can affect the Hall switch, and the voltage of the Hall switch will change. The controller controls the dust bag assembly 20 to work according to the voltage change of the Hall switch. Compared with the prior art, the dust collecting device 200 of this embodiment replaces the mechanical triggering method with a contactless triggering method, so that the resistance of the cover 30 covering the shell 10 is eliminated, and the influence of foreign matter such as dust on the cover 30 and the shell 10 is avoided. It also reduces a lot of installation holes, and the structure is simpler and stronger, so that the overall appearance of the dust collecting device 200 is better, and the service life of the dust collecting device 200 can be extended.

[0070] See also Figure 3In this embodiment, a cleaning robot system 1000 is also disclosed, including a cleaning robot 100 and the dust collecting device 200, wherein the cleaning robot 100 can automatically dock with the dust collecting device 200, so that the dust collecting device 200 extracts the garbage of the cleaning robot 100 into the dust bag assembly 20. The cleaning robot system 1000 having the dust collecting device 200 in this embodiment also has the above advantages, which will not be described in detail.
