[0030] The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0031] Embodiment 1

[0032] See also Figure 1 , Figure 3 , Figure 5 The embodiment of the present invention provides a dust collecting device, comprising a housing 100, a dust bag assembly 200 detachably installed in the housing 100, a housing cover 300 capable of covering or opening the housing 100, and a trigger structure 400, a detection switch 500 and a controller (not shown in the figure) all arranged in the housing 100, wherein the trigger structure 400 can be movably moved between an initial position and a trigger position, the trigger structure 400 does not trigger the detection switch 500 in the initial position, and the trigger structure 400 can trigger the detection switch 500 in the trigger position; when the dust bag assembly 200 is installed in the housing 100 and the housing cover 300 covers the housing 100, the dust bag assembly 200 and the housing cover 300 respectively push the trigger structure 400, so that the trigger structure 400 moves from the initial position to the trigger position and triggers the detection switch 500; the controller is electrically connected to the detection switch 500, and the controller limits the operation of the dust collecting device according to the untriggered state of the detection switch 500, and the controller releases the restriction on the operation of the dust collecting device according to the triggered state of the detection switch 500.

[0033] First of all, it should be explained that when the dust collecting device is working, the dust bag assembly 200 is placed in the box body 100, and the box cover 300 covers the box body 100. At this time, dust and other impurities can be introduced into the dust bag assembly 200 through the dust suction pipe 121 of the box body 100; when the dust collecting device is suspended, the operator can open the box cover 300, open the box body 100, and then take the dust bag assembly 200 out of the box body 100, and clean the impurities in the dust bag assembly 200. After cleaning, the dust bag assembly 200 can be put back into the box body 100 to wait for the dust collecting device to work.

[0034] Therefore, before the dust collecting device works, the present embodiment realizes the associated detection of whether the dust bag assembly 200 is in place (i.e., whether the dust bag assembly 200 is put back into the box 100) and whether the box cover 300 covers the box 100 through the trigger structure 400 and the detection switch 500, and feeds back the detection result to the controller, which then limits or releases the limit on the operation of the dust collecting device. The structure is simple and the performance is good.

[0035] Specifically, Figure 3 , Figure 4 , Figure 5 As shown, when the dust bag assembly 200 is first put back into the box body 100 and the box cover 300 is then closed on the box body 100, the trigger structure 400 is pushed successively by the dust bag assembly 200 and the box cover 300 and moves from the initial position to the trigger position. The trigger structure 400 triggers the detection switch 500 at the trigger position. After obtaining the signal that the detection switch 500 is in the triggered state, the controller releases the restriction on the operation of the dust collection device. At this time, the dust collection device is allowed to work or suspend work as needed.

[0036] On the contrary, if Figure 6 As shown, when the box cover 300 opens the box body 100 and / or the dust bag assembly 200 is taken out of the box body 100, the trigger structure 400 cannot be pushed successively by the dust bag assembly 200 and the box cover 300, and thus cannot reach the trigger position, and further cannot trigger the detection switch 500. During this period, the detection switch 500 is in an untriggered state. The controller can continuously restrict the operation of the dust collection device while obtaining a signal that the detection switch 500 is in an untriggered state until the dust bag assembly 200 is put back into the box body 100 and the box cover 300 covers the box body 100.

[0037] In summary, the dust collecting device provided by the embodiment of the present invention, when the box cover 300 is opened and the box body 100 and / or the dust bag assembly 200 is taken out of the box body 100, the detection switch 500 is in an untriggered state, and the dust collecting device is continuously restricted from operating through the controller during the period when the detection switch 500 is in the untriggered state; and when the dust bag assembly 200 is first put back into the box body 100 and the box cover 300 is closed again, the trigger structure 400 is pushed in succession by the dust bag assembly 200 and the box cover 300, so that the trigger structure 400 moves from the initial position to the trigger position and triggers the detection switch 500, and then, after obtaining a signal that the detection switch 500 is in the triggered state, the controller can release the restriction on the operation of the dust collecting device, allowing the dust collecting device to operate or suspend operation as needed. Therefore, the dust collecting device provided in the embodiment of the present invention can realize the associated detection of whether the dust bag assembly 200 is in place and whether the box cover 300 covers the box body 100 through the trigger structure 400 and the detection switch 500, and then based on the state of the detection switch 500, the operation of the dust collecting device is limited or released through the controller. The structure is simple and the detection accuracy is high. The situation that the dust collecting device cannot work normally due to the dust bag assembly 200 being installed in place but the box cover 300 not being covered can be basically avoided, thereby improving the performance.

[0038] 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.

[0039] Optionally, when the trigger structure 400 is in the trigger position, the detection switch 500 is pressed by the trigger structure 400 and switches from the untriggered state to the triggered state. Specifically, when the trigger structure 400 reaches the trigger position, the trigger structure 400 can press the detection switch 500 to switch the detection switch 500 from the untriggered state to the triggered state; conversely, when the trigger structure 400 leaves the trigger position, the detection switch 500 is released from being pressed and switches from the triggered state back to the untriggered state. With such a configuration, the switching of the detection switch 500 between the untriggered state and the triggered state can be realized simply, accurately and instantly, and the sensitivity of the state switching of the detection switch 500 can be improved, thereby improving the detection accuracy.

[0040] Optionally, the detection switch 500 may be a micro switch. With such a configuration, the trigger structure 400 can use a very small force to achieve the state switching of the detection switch 500 between the untriggered state and the triggered state, so that the state switching operation of the detection switch 500 can be sensitive and immediate, thereby improving the detection accuracy and sensitivity of "whether the dust bag assembly 200 is in place" and "whether the box cover 300 covers the box body 100", and can further improve the performance of the dust collection device.

[0041] Of course, in other possible implementations, the detection switch 500 can be switched from the untriggered state to the triggered state by being toggled by the trigger structure 400. The detection switch 500 can be a Hall sensor, a push button switch, a rocker switch, a toggle switch, or a toggle switch, etc., which is not limited in this embodiment.

[0042] See also Figure 3 , Figure 4 , Figure 5 In this embodiment, the trigger structure 400 can move to a preparation position, which is located between the initial position and the trigger position. The trigger structure 400 does not trigger the detection switch 500 at the preparation position; the dust bag assembly 200 is installed in the box body 100 and pushes the trigger structure 400 to move from the initial position to the preparation position, so that the box cover 300 covers the box body 100 and pushes the trigger structure 400 to continue to move from the preparation position to the trigger position.

[0043] Specifically, the dust bag assembly 200 is first put back into the box body 100. At this time, the trigger structure 400 is pushed by the dust bag assembly 200 and moves from the initial position to the preparatory position. Subsequently, the box cover 300 covers the box body 100 again, and the trigger structure 400 is pushed by the box cover 300 and moves from the preparatory position to the trigger position. The trigger structure 400 can trigger the detection switch 500 at the trigger position. After obtaining the signal that the detection switch 500 is in the triggered state, the controller releases the restriction on the operation of the dust collection device, allowing the dust collection device to work or suspend work as needed.

[0044] If the dust bag assembly 200 is not put back into the box body 100, the trigger structure 400 will not be able to reach the ready position. At this time, even if the box cover 300 is closed on the box body 100, the box cover 300 cannot push the trigger structure 400 that is not in the ready position, and thus cannot trigger the detection switch 500 through the trigger structure 400. During this period, the controller maintains the restriction on the operation of the dust collection device based on the untriggered state of the detection switch 500 until the dust bag assembly 200 is first put back into the box body 100 and the box cover 300 is closed on the box body 100.

[0045] Therefore, by adopting the above solution, the detection accuracy of the associated detection of whether the dust bag assembly 200 is in place and whether the box cover 300 covers the box body 100 can be further improved, the risk of misjudgment can be reduced, and the dust collection device can be guaranteed to work normally as required, thereby improving the performance.

[0046] See also Figure 2 , Figure 4 , Figure 5In this embodiment, the trigger structure 400 is provided with a first force-bearing portion 410, and the first force-bearing portion 410 is located on the side of the trigger structure 400 close to the dust bag assembly 200. The dust bag assembly 200 is provided with a card plate 210 detachably connected to the box body 100 and a first thrust portion 211 attached to the card plate 210. The first thrust portion 211 moves to the initial position as the card plate 210 is installed in the box body 100 to push the first force-bearing portion 410 from the initial position to the preparatory position; the trigger structure 400 is provided with a second force-bearing portion 420, and the second force-bearing portion 420 is located on the side of the trigger structure 400 close to the top of the box body 100. The box cover 300 is provided with a second thrust portion 310 on the side close to the top of the box body 100. The second thrust portion 310 moves to the preparatory position as the box cover 300 is closed on the top of the box body 100 to push the second force-bearing portion 420 from the preparatory position to the trigger position.

[0047] Based on the above structure, when the dust bag assembly 200 is put back into the box 100 and the clamping plate 210 is installed in place, the first thrust part 211 can push the first force-bearing part 410 relatively, so that the trigger structure 400 moves from the initial position to the preparatory position; then, the box cover 300 covers the box 100 again, and the second thrust part 310 can push the second force-bearing part 420 relatively, so that the trigger structure 400 moves from the preparatory position to the trigger position, thereby triggering the detection switch 500. Therefore, by adopting the above solution, the activities of the dust bag assembly 200 and the box cover 300 and the trigger structure 400 can be reliably associated, the structure is simple, and the detection accuracy can be further improved, the risk of misjudgment can be reduced, and the use performance can be further improved.

[0048] See also Figure 1 , Figure 4 , Figure 6 In this embodiment, the box body 100 is provided with an installation side wall 122 and a card slot 1221 formed on the installation side wall 122. The first force-bearing portion 410 is arranged through the installation side wall 122 at the initial position. The card plate 210 is detachably installed in the card slot 1221 and fits the installation side wall 122 to push the first force-bearing portion 410 to contract relative to the installation side wall 122.

[0049] By adopting the above solution, the card plate 210 can be quickly and accurately installed in place through the cooperation between the card plate 210 and the card slot 1221, so as to facilitate the dust bag assembly 200 to be placed in place, and facilitate the first thrust part 211 to push the first force-bearing part 410 relatively to move the trigger structure 400 from the initial position to the preparatory position. Therefore, the convenience of assembling the dust bag assembly 200 and the box 100 can be improved, and the reliability of the association between the activities of the dust bag assembly 200 and the trigger structure 400 can be improved.

[0050] See also Figure 3 , Figure 4 , Figure 6In this embodiment, at least one of the first force-bearing portion 410 and the first thrust portion 211 is provided with a first guide surface 411, and the first guide surface 411 is inclined relative to a preset horizontal direction. The first guide surface 411 is used to guide the first thrust portion 211 to apply a first horizontal thrust to the first force-bearing portion 410.

[0051] By adopting the above solution, when the dust bag assembly 200 is placed into the box 100 from top to bottom, the first thrust part 211 can achieve transitional push-fitting with the first force-bearing part 410 along the first guide surface 411, and gradually push the first force-bearing part 410 to shrink relative to the installation side wall 122, so as to move the trigger structure 400 from the initial position to the preparatory position. Therefore, based on the setting of the first guide surface 411, the risk of the first thrust part 211 and the first force-bearing part 410 being stuck can be effectively reduced, the reliability of the association between the dust bag assembly 200 and the trigger structure 400 can be improved, the smoothness of the activity of the trigger structure 400 can be improved, and the use performance can be improved.

[0052] The first guiding surface 411 disposed on the first force-bearing portion 410 is upward and faces the first thrust portion 211 ; and the first guiding surface disposed on the first thrust portion 211 is downward and faces the first force-bearing portion 410 .

[0053] See also Figure 2 , Figure 4 , Figure 5 In this embodiment, at least one of the second force-bearing portion 420 and the second thrust portion 310 is provided with a second guide surface 421, and the second guide surface 421 is inclined relative to a preset horizontal direction. The second guide surface 421 is used to guide the second thrust portion 310 to apply a second horizontal thrust to the second force-bearing portion 420, and the second horizontal thrust is consistent with the direction of the first horizontal thrust.

[0054] Based on the setting of the second guide surface 421, when the dust bag assembly 200 has been placed in the box body 100 and the box cover 300 gradually covers the box body 100, the second thrust portion 310 can achieve a transitional push-fit with the second force-bearing portion 420 along the second guide surface 421, and gradually push the second force-bearing portion 420 from the preparation position to the trigger position. Based on this, the risk of jamming of the cooperation between the second thrust portion 310 and the second force-bearing portion 420 can be effectively reduced, the reliability of the association between the activities of the box cover 300 and the trigger structure 400 can be improved, the smoothness of the activities of the trigger structure 400 can be improved, and the performance of use can be improved.

[0055] By setting the second horizontal thrust in the same direction as the first horizontal thrust, the movement path of the trigger structure 400 from the initial position, the preparation position to the trigger position can be basically in a straight line. Based on this, the smoothness of the movement of the trigger structure 400 can be further improved, especially the resetting of the trigger structure 400 is convenient, which is beneficial to reduce the risk of the trigger structure 400 getting stuck, and can improve reliability and usability.

[0056] See also Figure 1 , Figure 4 , Figure 5 In this embodiment, the first thrust portion 211 is protruded from a side of the clamping plate 210 close to the trigger structure 400 , and / or the second thrust portion 310 is protruded from a side of the box cover 300 close to the trigger structure 400 .

[0057] By adopting the above scheme, the trigger structure 400 can be reliably and conveniently pushed by the protruding first thrust portion 211 and / or the second thrust portion 310. Based on this, the reliability of the association between the activities of the dust bag assembly 200 and / or the box cover 300 and the trigger structure 400 can be further improved, and the activity stroke of the trigger structure 400 can be guaranteed or even extended, thereby further improving the performance.

[0058] See also Figure 3 , Figure 4 , Figure 5 In this embodiment, the first thrust portion 211 pushes the first force-bearing portion 410 from the initial position to the preparatory position along the first direction, and the second thrust portion 310 pushes the second force-bearing portion 420 from the preparatory position to the trigger position along the second direction, wherein the first direction and the second direction are the same preset horizontal direction.

[0059] By adopting the above scheme, the movement path of the trigger structure 400 from the initial position, the preparation position to the trigger position can be made basically in a straight line. Based on this, the smoothness of the movement of the trigger structure 400 can be further improved, especially facilitating the resetting of the trigger structure 400, which is beneficial to reducing the risk of the trigger structure 400 getting stuck and improving reliability and usability.

[0060] See also Figure 2 , Figure 4 , Figure 5 In this embodiment, the trigger structure 400 is provided with a third thrust portion 450 for pressing the detection switch 500 .

[0061] By adopting the above solution, the trigger structure 400 can reliably and continuously press the detection switch 500 through the third thrust portion 450 at the trigger position, so that the detection switch 500 maintains the trigger state, and the use performance is better.

[0062] Optionally, the detection switch 500 is arranged on the side of the trigger structure 400 away from the box cover 300. Such a layout is conducive to compressing the horizontal space occupied by the trigger structure 400 and the detection switch 500, thereby facilitating the miniaturization design of the dust collection device.

[0063] See also Figure 1 , Figure 4 , Figure 5 In this embodiment, the dust collecting device further includes an elastic member 600, which elastically connects the trigger structure 400 and the housing 100 to provide an elastic restoring force for the trigger structure 400 to move toward the direction close to the initial position.

[0064] It should be noted that when the trigger structure 400 moves from the initial position to the preparation position and then from the preparation position to the trigger position, the elastic member 600 generates elastic deformation and stores elastic restoring force that causes the trigger structure 400 to move toward the initial position when the push is released.

[0065] Specifically, the box cover 300 first opens the box body 100, the box cover 300 releases the push trigger structure 400, and the elastic force of the elastic member 600 can cause the trigger structure 400 to reset from the trigger position to the ready position. At this time, the detection switch 500 has switched from the triggered state to the untriggered state. Subsequently, the dust bag assembly 200 is taken out of the box body 100 again, and the dust bag assembly 200 releases the push trigger structure 400, and the elastic force of the elastic member 600 can further cause the trigger structure 400 to reset from the ready position to the initial position. During this period, the detection switch 500 always maintains the untriggered state. The controller maintains the restriction on the dust collection device to work based on the untriggered state of the detection switch 500 until the dust bag assembly 200 is first put back into the box body 100 and the box cover 300 closes the box body 100 again.

[0066] Therefore, by adopting the above scheme, the elastic restoring force of the elastic member 600 can enable the trigger structure 400 to move immediately toward the initial position when the box cover 300 releases the push against the trigger structure 400, thereby immediately releasing the trigger detection switch 500 and causing the detection switch 500 to switch back to the untriggered state immediately, thereby enabling the controller to immediately limit the operation of the dust collection device, thereby improving the performance. The elastic restoring force of the elastic member 600 can also enable the trigger structure 400 to reset to the initial position, thereby facilitating the trigger structure 400 and the detection switch 500 to detect "whether the dust bag assembly 200 is in place" and "whether the box cover 300 covers the box body 100" in association with each other, thereby improving the detection accuracy, ensuring that the dust collection device can work normally as required, and improving the performance.

[0067] See also Figure 1 , Figure 3 , Figure 4In this embodiment, the box body 100 includes a box body 110, a dust bag bracket 120 installed in the box body 110, and a detection bracket 130 connected to the dust bag bracket 120 away from the dust bag assembly 200, and the detection bracket 130 is provided with a limiting hole 131; the trigger structure 400 includes a trigger body 430 and a guide column 440 connected to the trigger body 430 away from the dust bag assembly 200, the guide column 440 is slidably fitted in the limiting hole 131, and the elastic member 600 elastically connects the trigger body 430 and the detection bracket 130.

[0068] First, it should be noted that the dust suction pipe 121 for connecting with the dust bag assembly 200 can be formed integrally with the dust bag bracket 120, and the trigger structure 400, the detection switch 500 and the elastic member 600 can be assembled to the detection bracket 130 accordingly, and then assembled by detachably connecting the detection bracket 130 with the dust bag bracket 120. Therefore, the structural setting of the box 100 of this embodiment can improve the processing convenience and assembly convenience of the box 100 and even the dust collecting device as a whole.

[0069] It should also be noted that this embodiment provides a possible assembly implementation example based on the setting that the movement path of the trigger structure 400 from the initial position, the preparatory position to the trigger position is basically a straight line. Specifically, the elastic member 600 is first sleeved on the outer peripheral side of the guide column 440, and then the end of the guide column 440 is inserted into the limiting hole 131. Based on this, the elastic member 600 will elastically support the side of the detection bracket 130 facing the trigger body 430 and the trigger body 430, and based on the plug-in matching relationship between the guide column 440 and the limiting hole 131, the movement path of the trigger structure 400 will be basically a straight line.

[0070] Therefore, when the dust bag assembly 200 is put back into the box body 100, the first thrust part 211 can push the trigger structure 400, so that the trigger structure 400 moves from the initial position to the preparatory position along the through direction of the limit hole 131. Then, the box cover 300 covers the box body 100 again, and the second thrust part 310 can push the second force-bearing part 420 to continue moving in the same direction, so that the trigger structure 400 further moves from the preparatory position to the trigger position, so that the detection switch 500 can be instantly pressed by the trigger structure 400, so that the detection switch 500 is switched from the untriggered state to the triggered state, and then the restriction on the dust collecting device is instantly released through the controller. During this period, the elastic member 600 produces compressive elastic deformation and accumulates force.

[0071] On the contrary, when the box cover 300 opens the box body 100, the second thrust portion 310 releases the resistance to the second force-bearing portion 420, the elastic member 600 can restore a part of the elastic deformation and prompt the trigger structure 400 to immediately reset from the trigger position to the preparatory position, so as to prompt the detection switch 500 to immediately switch from the triggered state to the untriggered state and restrict the dust collecting device from working. Subsequently, the dust bag assembly 200 is taken out of the box body 100, the first thrust portion 211 releases the resistance to the trigger structure 400, the elastic member 600 can basically restore the elastic deformation and further prompt the trigger structure 400 to reset from the preparatory position to the initial position, so as to facilitate the next associated detection work.

[0072] Therefore, by adopting the above solution, the moving path of the trigger structure 400 can be guided, so as to facilitate the smoothness of the movement of the trigger structure 400, facilitate the resetting of the trigger structure 400, further reduce the risk of the trigger structure 400 getting stuck, and further improve reliability and usability.

[0073] See also Figure 1 , an embodiment of the present invention also provides a cleaning robot system, including a cleaning robot and a dust collecting device.

[0074] Among them, the cleaning robot can be a household or commercial service robot with garbage cleaning and garbage storage functions such as a sweeper, a sweeper and mop, a floor scrubber, and a floor washer. Specifically, when the cleaning robot is working, impurities such as dust, hair, or paper scraps in the cleaning area can be stored in the garbage storage chamber inside the cleaning robot. Therefore, after the cleaning robot has been working for a period of time, the dust discharge port of the cleaning robot can be docked with the dust suction port of the dust collecting device. In this way, when the dust collecting device is working, the impurities originally stored in the garbage storage chamber inside the cleaning robot can be introduced into the dust bag assembly 200 through the dust suction port and the dust suction pipe 121 of the box 100, and the transfer and collection of impurities are completed; and when the dust collecting device is suspended, the operator can open the box cover 300, open the box 100, and then take the dust bag assembly 200 out of the box 100, and clean the impurities in the dust bag assembly 200. After cleaning, the dust bag assembly 200 can be put back into the box 100 to wait for the next work of the dust collecting device.

[0075] Embodiment 2

[0076] The difference between this embodiment and the first embodiment is that:

[0077] Please refer to Figure 4 , Figure 5In this embodiment, the first thrust portion 211 pushes the first force-bearing portion 410 from the initial position to the preparatory position along the first direction, and the second thrust portion 310 pushes the second force-bearing portion 420 from the preparatory position to the trigger position along the second direction, wherein the first direction is a horizontal direction and the second direction is a vertical direction.

[0078] By adopting the above solution, the trigger structure 400 can move from the initial position to the preparatory position along the first direction under the push action of the first thrust portion 211, and then move from the preparatory position to the trigger position along the second direction perpendicular to the first direction under the push action of the second thrust portion 310, and trigger the detection switch 500. Based on the movement path setting of the trigger position of this embodiment, the detection switch 500 can also be reliably triggered and released.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
