[0034] For ease of understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on another element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to another element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0035] 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.

[0036] 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.

[0037] Please refer to Figures 1 to 6 , this embodiment discloses a dust collecting device 100, including a housing 10, a cover 20, a dust bag assembly 30, a swing rod 40, a non-contact induction switch 50, a non-contact trigger 60 and a controller (not shown in the figure);

[0038] The cover 20 covers the housing 10, the dust bag assembly 30 is detachably mounted in the housing 10, the swing rod 40 is rotatably mounted on the housing 10, a trigger portion 42 is provided at a first end of the swing rod 40, one of the non-contact induction switch 50 and the non-contact trigger member 60 is mounted at a second end of the swing rod 40, the other of the non-contact induction switch 50 and the non-contact trigger member 60 is mounted on the cover 20, and the non-contact induction switch 50 is electrically connected to the controller;

[0039] When the dust bag assembly 30 is installed in the housing 10, the dust bag assembly 30 can push the trigger portion 42, so that the swing rod 40 rotates to drive one of the non-contact sensing switch 50 and the non-contact trigger member 60 to move from an initial position to a preset position; and when the cover body 20 is covered on the housing 10, the non-contact trigger member 60 can trigger the non-contact sensing switch 50, so that the non-contact sensing switch 50 assembly generates a trigger signal;

[0040] When the controller determines that the non-contact induction switch 50 component generates a trigger signal, the controller controls the dust collecting device 100 to start the dust collecting action.

[0041] In one embodiment, the non-contact induction switch 50 is installed in the housing 10, and the non-contact trigger 60 is installed on the cover 20. When the dust bag assembly 30 is not installed in the housing 10, the non-contact induction switch 50 on the swing rod 40 is in the initial position. When the dust bag assembly 30 is installed in the housing 10, the dust bag assembly 30 pushes the swing rod 40 through the trigger part 42, so that the swing rod 40 pushes the non-contact induction switch 50 from the initial position to the preset position. At this time, if the cover 20 is also covered on the housing 10, the non-contact trigger 60 can trigger the non-contact induction switch 50, so that the non-contact induction switch 50 assembly generates a trigger signal; when the controller determines that the non-contact induction switch 50 assembly generates a trigger signal, it controls the dust collection device 100 to start the dust collection action.

[0042] Therefore, only when the dust bag assembly 30 is installed in the shell 10 and the cover body 20 is covered on the shell 10, the non-contact trigger member 60 can trigger the non-contact sensing switch 50. If only the dust bag assembly 30 is installed in the shell 10 and the cover body 20 is not covered on the shell 10, or only the cover body 20 is covered on the shell 10 and the dust bag assembly 30 is not installed in the shell 10, the non-contact trigger member 60 cannot trigger the non-contact sensing switch 50 to generate a trigger signal, that is, the dust collection device 100 will not operate.

[0043] In the dust collecting device 100 of this embodiment, a non-contact sensing control method is adopted instead of a mechanical triggering method, so that the resistance when the cover body 20 is closed is eliminated, dust can be prevented from obstructing the movement of the mechanical structure, and the cover body 20 can be prevented from being difficult to close. The number of holes and grooves on the shell 10 and the cover body 20 is reduced, and the appearance integrity of the product is better.

[0044] Secondly, the dust bag assembly 30 pushes the swing rod 40 through the trigger part 42, so that the non-contact induction switch 50 on the swing rod 40 swings from the initial position to the preset position. Therefore, the dust bag assembly 30 can move the second end of the swing rod 40 by a large distance by pushing the trigger part 42, so that the second end of the swing rod 40 and the non-contact induction switch 50 have a large stroke. When the non-contact induction switch 50 on the swing rod 40 is at the initial position, if the cover body 20 is covered on the housing 10, since the initial position is far from the preset position, the non-contact trigger 60 will not trigger the non-contact induction switch 50 at the initial position. At this time, there is no need to set a barrier sheet to isolate the influence between the non-contact trigger 60 and the non-contact induction switch 50.

[0045] It is understandable that, according to actual needs, the non-contact induction switch 50 can also be installed on the cover 20, and the non-contact trigger 60 is installed on the second end of the swing rod 40. The controller can be a microcontroller (Microcontroller Unit; MCU), for example, the controller can be an ARM Cortex-M4-32-bit microcontroller, which is not limited in this embodiment.

[0046] Please refer to Figure 6 and Figure 7 The dust bag assembly 30 includes a bag body 32 and a plug board 34 connected to the bag body 32. The bag body 32 is a filter bag. The material of the bag body 32 can be plastic, paper or a composite material, which is not specifically limited here, and can be set by those skilled in the art according to actual needs.

[0047] Please refer to Figures 8 to 11 In one embodiment, the dust collecting device 100 further includes an air inlet channel 70, a dust removal channel (not marked in the figure) and a dust removal fan 80. The dust removal fan 80 is located in the dust removal channel. The air inlet channel 70, the dust bag assembly 30 and the dust removal channel are connected in sequence. When the dust removal fan 80 is working, it provides vacuum negative pressure. Under the action of vacuum negative pressure, the air inlet channel 70 can introduce airflow to the dust bag assembly 30, and then the airflow can pass through the dust bag assembly 30 and enter the dust removal channel for discharge, wherein the dust bag assembly 30 can play a filtering role and intercept dust and debris carried in the airflow. A through hole 342 is provided on the plug plate 34. The air inlet channel 70 is connected to the bag body 32 through the through hole 342, and the bag body 32 is also connected to the dust removal channel. The end of the air inlet channel 70 is a dust suction port 72, and the air inlet channel 70 is connected to the outside through the dust suction port 72.

[0048] In one embodiment, the housing 10 is provided with a first cavity 12, a second cavity 14, and an isolation bracket 16 separating the first cavity 12 from the second cavity 14. The dust bag assembly 30 is detachably mounted in the first cavity 12. The swing arm 40 is rotatably mounted on the isolation bracket 16, and the swing arm 40 is located in the second cavity 14. The isolation bracket 16 is provided with a slot 122 on one side close to the first cavity 12. The isolation bracket 16 is provided with an opening 124 at the side wall corresponding to the slot 122, and the trigger portion 42 extends into the slot 122 through the opening 124. The isolation bracket 16 separates the first cavity 12 from the second cavity 14, so that the dust bag assembly 30 and the non-contact induction switch 50 can be independent of each other, do not interfere with each other, and avoid errors. When the dust bag assembly 30 is placed in the first cavity 12, the plug board 34 of the dust bag assembly 30 is placed along the slot 122, and the dust bag assembly 30 can push the trigger portion 42 out of the opening 124.

[0049] In one embodiment, the isolation bracket 16 is provided with a rotating shaft 162, a connecting portion 164 and a torsion spring 166, the rotating shaft 162 and the connecting portion 164 are located in the second cavity 14, the swing rod 40 and the torsion spring 166 are provided on the rotating shaft 162, one end of the torsion spring 166 is connected to the connecting portion 164, and the other end of the torsion spring 166 is connected to the swing rod 40, so as to push the swing rod 40 to rotate toward the initial position. The connecting portion 164 is used to fix one end of the torsion spring 166, and the main body of the torsion spring 166 is sleeved on the rotating shaft 162. Specifically, the connecting portion 164 is a slot, one end of the torsion spring 166 is clamped in the slot, and the other end of the torsion spring 166 is connected to the swing rod 40, so as to push the swing rod 40 to swing toward the initial position. When the dust bag assembly 30 is not installed in the first cavity 12, the non-contact sensing switch 50 on the swing arm 40 is in the initial position under the push of the torsion spring 166. When the dust bag assembly 30 is placed in the first cavity 12, the swing arm 40 is pushed so that the non-contact sensing switch 50 on the swing arm 40 is in the preset position. However, when the dust bag assembly 30 is taken out again, the non-contact sensing switch 50 on the swing arm 40 automatically returns to the initial position under the action of the torsion spring 166. Therefore, the torsion spring 166 has a resetting function.

[0050] It is understandable that, according to actual needs, other elastic elements may be used instead of the torsion spring 166 .

[0051] In one embodiment, the isolation bracket 16 is provided with two slots 122 arranged opposite to each other, and a positioning surface 126 located between the two slots 122, and the rotation axis 162 is perpendicular to the positioning surface 126; the plug board 34 is plugged into the slots 122. The two slots 122 guide the plug board 34, and the positioning surface 126 positions the plug board 34. The rotation axis 162 is perpendicular to the positioning surface 126, so that the swing plane of the swing rod 40 is parallel to the positioning surface 126, so that the space can be reasonably used, and the swing rod 40 will not interfere with the dust bag assembly 30.

[0052] In one embodiment, the slot 122 has an open notch 1222, the plug plate 34 is inserted into the slot 122 through the notch 1222, the trigger portion 42 has a force-bearing surface 422 facing the side where the notch 1222 is located, the force-bearing surface 422 is inclined relative to the extension direction of the slot 122, and the plug plate 34 pushes the swing rod 40 to rotate toward the preset position through the force-bearing surface 422. When the dust bag assembly 30 is placed in the first cavity 12, the plug plate 34 of the dust bag assembly 30 falls into the slot 122, and the plug plate 34 can push the trigger portion 42 through the force-bearing surface 422, thereby pushing the non-contact induction switch 50 on the swing rod 40 from the initial position to the preset position. The notch 1222 has a guiding function, and the plug plate 34 can quickly and accurately enter the slot 122 through the notch 1222, and the force-bearing surface 422 also has a buffering function.

[0053] In one embodiment, the pendulum rod 40 includes a rotation center portion 44, the first end of the pendulum rod 40 and the second end of the pendulum rod 40 are respectively located on both sides of the rotation center portion 44, the rotation center portion 44 is rotatably connected to the shell 10, there is a first distance between the first end of the pendulum rod 40 and the rotation center portion 44, there is a second distance between the second end of the pendulum rod 40 and the rotation center portion 44, and the second distance is greater than the first distance. The rotating center portion 44 is rotatably connected to the rotating shaft 162. When the second distance is greater than the first distance, when the bag body 32 touches the trigger portion 42, the second end of the rocker arm 40 can move a larger distance, thereby making the second end of the rocker arm 40 have a larger stroke. When the bag body 32 does not touch the trigger portion 42, the second end of the rocker arm 40 and the non-contact sensing switch 50 are in the initial position, and the second end of the rocker arm 40 and the non-contact sensing switch 50 can be far away from the preset position. When the cover body 20 is covered on the shell 10 and the dust bag assembly 30 is not installed in the shell 10, the non-contact trigger member 60 will not trigger the non-contact sensing switch 50 to generate a trigger signal, and will not cause misjudgment. The influence of the non-contact trigger member 60 on the non-contact sensing switch 50 can be completely eliminated, and there is no need to set a barrier sheet.

[0054] In one embodiment, the swing rod 40 further includes a first rod portion 46 and a second rod portion 48, the first rod portion 46 and the second rod portion 48 are respectively connected to the two sides of the rotation center portion 44, the first rod portion 46 is provided with the first end, the second rod portion 48 is provided with the second end, the second rod portion 48 and the first rod portion 46 are arranged at an obtuse angle, when the second end of the swing rod 40 is in the preset position, the second end of the swing rod 40 faces directly above the dust collecting device 100; the swing rod 40 rotates from the initial position to the preset position by a preset angle, wherein the preset angle is an acute angle. Among them, the side of the housing 10 close to the cover body 20 is the front side, and directly above the dust collecting device 100 refers to the direction facing the front side. When the dust bag assembly 30 is placed in the first cavity 12 of the housing 10, that is, when the second end of the swing rod 40 and the non-contact induction switch 50 are located at the preset position, the first rod portion 46 and the slot 122 are parallel, so that the non-contact induction switch 50 located at the first rod portion 46 is closest to the top surface of the housing 10. If at this time, when the cover body 20 is covered on the housing 10, the center of the non-contact induction switch 50 and the center of the non-contact trigger member 60 can basically be opposite, so that the non-contact trigger member 60 can accurately trigger the non-contact induction switch 50, so that the non-contact induction switch 50 generates a trigger signal, so that the dust collection device 100 enters the working state. Therefore, even if the cover body 20 is covered on the housing 10 at this time, the non-contact trigger member 60 will not trigger the non-contact induction switch 50, and will not cause misjudgment. When the dust bag assembly 30 is installed in the first cavity 12 of the housing 10, and the cover body 20 is covered on the housing 10, the non-contact induction switch 50 can be closer to the non-contact trigger member 60. When the dust bag assembly 30 is not placed in the first cavity 12 of the shell 10 , the non-contact sensing switch 50 at the initial position is far away from the preset position. Further preferably, the first end of the first rod portion 46 is provided with a fixing groove 462 , and the non-contact sensing switch 50 is clamped in the fixing groove 462 .

[0055] In one embodiment, the isolation bracket 16 is further provided with a stopper 168, and the stopper 168 is located at the initial position to stop the second end of the swing rod 40 at the initial position. The stopper 168 and the connecting portion 164 are respectively located on both sides of the swing rod 40. When the dust bag assembly 30 is not installed in the housing 10, the torsion spring 166 pushes the swing rod 40 so that the second end of the swing rod 40 is blocked at the initial position, so that the non-contact induction switch 50 can be in the initial position. When the dust bag assembly 30 is not installed in the housing 10, the first rod 46 is tilted, and a preset angle can be formed between the first rod 46 and the slot 122, and the preset angle is an acute angle. The stopper 168 has a limiting effect on the swing rod 40 and the non-contact induction switch 50. Specifically, when the swing rod 40 is pressed against the stopper 168 under the action of the torsion spring 166, the contact surface of the swing rod 40 and the stopper 168 fits. It can prevent the swing rod 40 and the stopper 168 from being damaged when they contact and collide.

[0056] Further preferably, the blocking portion 168 includes a blocking piece 1682 and a reinforcing piece 1684, and the blocking piece 1682 and the reinforcing piece 1684 are respectively erected on the sides of the isolation bracket 16, and the reinforcing piece 1684 is connected below the blocking piece 1682, and the blocking piece 1682 is tilted. When the rocker arm 40 and the non-contact sensing switch 50 are in the initial position, the contact surface of the blocking piece 1682 and the rocker arm 40 fits together, and an angle is formed between the reinforcing piece 1684 and the blocking piece 1682, and the reinforcing piece 1684 has the function of reinforcing support for the blocking piece 1682.

[0057] It is understandable that, according to actual needs, the non-contact induction switch 50 can also be an infrared induction switch, and the non-contact triggering member 60 is a structure that can trigger the infrared induction switch.

[0058] In one embodiment, the non-contact induction switch 50 is a Hall switch, and the non-contact trigger 60 is a magnetic member. 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 the output is 0V; in this embodiment, whether the dust bag assembly 30 is installed in the first cavity 12 of the housing 10, and whether the cover 20 is covered on the housing 10, is associated with the change of the Hall switch voltage, thereby controlling whether the dust bag assembly 30 can enter the working state.

[0059] This embodiment also discloses a cleaning robot system, including a cleaning robot and the dust collecting device 100, wherein the cleaning robot can automatically dock with the dust collecting device 100 so that the dust collecting device 100 extracts the garbage of the cleaning robot into the dust bag assembly 30. The cleaning robot system with the dust collecting device 100 of this embodiment also has the above advantages, which will not be described in detail here.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they may still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
