[0032] The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0033] Embodiment 1

[0034] See also Figure 2 , Figure 3 , Figure 6 The embodiment of the present invention provides a dust collecting device, including a box body 100 and a dust bag assembly 200 detachably installed in the box body 100, the box body 100 includes a box body (not shown in the figure), a dust bag bracket 110 installed in the box body, and a dust inlet channel 120 fixed to one side of the dust bag bracket 110, the dust bag assembly 200 includes a handle bracket 220 for detachably connecting with the dust bag bracket 110 and a dust collecting bag 210 connected with the handle bracket 220, one of the dust bag bracket 110 and the handle bracket 220 is provided with a vent pipe 111, and the other one is provided with a vent hole 221, the vent pipe 111 and the vent hole 221 can be plugged and matched to connect the dust inlet channel 120 and the dust collecting bag 210.

[0035] Specifically, when the ventilation tube 111 is protrudingly provided on the side of the dust bag bracket 110 away from the dust inlet passage 120, the handle bracket 220 is correspondingly provided with a ventilation hole 221 into which the ventilation tube 111 can be inserted. Conversely, when the ventilation tube 111 is protrudingly provided on the side of the handle bracket 220 away from the dust bag 210, the dust bag bracket 110 is correspondingly provided with a ventilation hole 221 into which the ventilation tube 111 can be inserted.

[0036] Based on this, the dust collecting device provided in the embodiment of the present invention can conveniently achieve the docking between the dust bag bracket 110 and the handle bracket 220 by aligning and plugging the ventilation pipe 111 and the ventilation hole 221 when the dust bag assembly 200 is installed in the box body 100. In this way, during the period when the dust collecting device is collecting dust, the air flow carrying dust and other impurities can be directly entered along the dust inlet channel 120 and the ventilation pipe 111 and penetrate into the dust collecting bag 210, thereby reducing the risk of dust and other impurities leaking from the docking point between the dust bag bracket 110 and the handle bracket 220, that is, reducing the risk of dust leakage, thereby ensuring and improving the dust collection effect of the dust collecting device.

[0037] When the dust collecting device stops working, the box body 100 can be opened, and then the plug-in relationship between the ventilation pipe 111 and the ventilation hole 221 can be released and the dust bag assembly 200 can be taken out from the box body 100 to clean the impurities in the dust bag 210. After cleaning, the dust bag assembly 200 can be installed back into the box body 100 to wait for the dust collection operation.

[0038] See also Figure 2 , Figure 3 , Figure 6 In this embodiment, an elastic sealing ring 222 is provided on the inner edge of the vent hole 221, and the elastic sealing ring 222 is sealed and fitted with the peripheral side of the vent pipe 111; the vent pipe 111 is a non-elastic pipe.

[0039] By adopting the above scheme, when the vent pipe 111 and the vent hole 221 are plugged in, the vent pipe 111 does not need to undergo elastic deformation or rebound, and the elastic sealing ring 222 based on the inner edge of the vent hole 221 is elastically sealed between the vent hole 221 and the vent pipe 111. Based on this, on the one hand, the sealing effect between the vent hole 221 and the vent pipe 111 can be guaranteed and improved to reduce the risk of dust leakage from the gap between the vent hole 221 and the vent pipe 111; on the other hand, the fitting resistance caused by the elastic force of the vent pipe 111 can be omitted, thereby reducing the difficulty of plug-in fitting between the vent hole 221 and the vent pipe 111 accordingly, that is, the plug-in fitting between the vent hole 221 and the vent pipe 111 can be achieved more conveniently and labor-savingly.

[0040] See also Figure 2 , Figure 3 , Figure 6 In this embodiment, a conical pipe section (not shown in the figure) is provided at one end of the vent pipe 111, and the vent hole 221 has a conical hole section (not shown in the figure) matched with the conical pipe section, and an elastic sealing ring 222 is provided on the inner edge of the conical hole section.

[0041] By adopting the above scheme, when the vent pipe 111 and the vent hole 221 are aligned and plugged in, the conical hole section can generate a greater normal pressure on the conical tube section that is perpendicular to the outer tube surface of the conical tube section. Based on this, the elastic sealing ring 222 on the inner edge of the conical hole section can be urged to elastically abut the outer tube surface of the conical tube section more tightly based on the greater normal pressure, thereby forming a more reliable, more effective and more airtight seal, which can further reduce the risk of ash leakage from the gap between the vent hole 221 and the vent pipe 111.

[0042] When the vent pipe 111 is arranged on the fixed bracket 300 and the vent hole 221 is arranged on the handle bracket 220, the cross-sectional dimension of the tapered pipe section perpendicular to the axis thereof is gradually expanded in the direction close to the fixed bracket 300, and the cross-sectional dimension of the tapered hole section perpendicular to the axis thereof is gradually expanded in the direction away from the handle bracket 220. On the contrary, when the vent pipe 111 is arranged on the handle bracket 220 and the vent hole 221 is arranged on the fixed bracket 300, the cross-sectional dimension of the tapered pipe section perpendicular to the axis thereof is gradually contracted in the direction away from the handle bracket 220, and the cross-sectional dimension of the tapered hole section perpendicular to the axis thereof is gradually contracted in the direction close to the fixed bracket 300. Such arrangement can ensure and reduce the difficulty of plugging in the vent pipe 111 and the vent hole 221, and ensure and improve the plugging convenience and plugging efficiency of the vent pipe 111 and the vent hole 221.

[0043] See also Figure 1 , Figure 2 , Figure 3In this embodiment, the dust collecting device further includes a fixing bracket 300 connected to the dust bag bracket 110 , and the fixing bracket 300 is used to fix the handle bracket 220 to the dust bag bracket 110 .

[0044] Specifically, when the dust bag assembly 200 is installed on the box body 100, the handle bracket 220 can be installed on the fixed bracket 300, and then the fixed bracket 300 is connected to the dust bag bracket 110, so that the handle bracket 220 and the dust bag bracket 110 are precisely aligned and precisely docked, and the installation convenience of the handle bracket 220 can be improved to a certain extent, and the installation effect of the handle bracket 220 can be stabilized.

[0045] On the contrary, the connection between the fixing bracket 300 and the dust bag bracket 110 can be released first, and then the handle bracket 220 can be removed from the fixing bracket 300 to facilitate the removal of the dust bag assembly 200 from the box body 100.

[0046] Also, please see Figure 5 , a door lock structure 400 can also be provided. When the fixed bracket 300 is connected to the dust bag bracket 110, the door lock structure 400 can be triggered to restrict the fixed bracket 300 from being disconnected from the dust bag bracket 110; and when the dust bag assembly 200 needs to be disassembled, the door lock structure 400 can be unlocked first, and then the fixed bracket 300 is disconnected from the dust bag bracket 110. Based on this, the installation firmness of the handle bracket 220 after installation can be further guaranteed and improved, and the risk of the dust bag assembly 200 accidentally falling out after being installed in the box 100 can be effectively reduced.

[0047] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, the fixed bracket 300 has a first end 310 rotatably connected to the dust bag bracket 110, and a second end 320 opposite to the first end 310, and the second end 320 is detachably connected to the dust bag bracket 110; the handle bracket 220 is detachably mounted on the fixed bracket 300, and can be switched between a first preset position and a second preset position as the fixed bracket 300 rotates. The handle bracket 220 docks with the dust bag bracket 110 at the first preset position, and enables the ventilation pipe 111 and the ventilation hole 221 to be plugged and matched. The handle bracket 220 is detached from the dust bag bracket 110 at the second preset position, and enables the ventilation pipe 111 and the ventilation hole 221 to be separated.

[0048] Specifically, the second end 320 of the fixed bracket 300 can be disconnected from the dust bag bracket 110, and then the second end 320 of the fixed bracket 300 can be rotated around the first end 310 thereof to the second preset position, so that the handle bracket 220 can be easily assembled and disassembled from the fixed bracket 300 at the second preset position; and when the handle bracket 220 is installed on the fixed bracket 300, the fixed bracket 300 can synchronously drive the handle bracket 220 to rotate from the second preset position to the first preset position, so that the vent pipe 111 and the vent hole 221 can be conveniently and accurately plugged, and the handle bracket 220 and the dust bag bracket 110 can be conveniently and accurately docked. During this period, the fixed bracket 300 does not need to be removed from the dust bag bracket 110, that is, the handle bracket 220 can be conveniently assembled and disassembled, thereby effectively improving the convenience of assembling and disassembling the handle bracket 220 and the dust bag assembly 200.

[0049] The second end 320 of the fixing bracket 300 may be optionally snap-connected to the dust bag bracket 110 .

[0050] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, the dust bag bracket 110 is provided with a mating surface 112, and the dust bag bracket 110 is provided with a vent 111 or a vent hole 221 on the mating surface 112. The handle bracket 220 is in contact with the mating surface 112 at a first preset position, and the handle bracket 220 is arranged at an angle relative to the mating surface 112 at a second preset position.

[0051] By making the handle bracket 220 in the second preset position be arranged at an angle with the matching surface 112 , a certain space can be formed between the handle bracket 220 and the matching surface 112 , so as to make it easier for operators to disassemble and assemble the handle bracket 220 .

[0052] On the contrary, by making the handle bracket 220 in the first preset position fit with the mating surface 112, the handle bracket 220 and the dust bag bracket 110 can be relatively tightly docked, thereby further reducing the risk of dust and other impurities leaking from the docking point between the dust bag bracket 110 and the handle bracket 220, that is, reducing the risk of dust leakage.

[0053] See also Figure 1 , Figure 2 , Figure 3 Please also refer to Figure 6 In this embodiment, the lower end of the fixing bracket 300 is the first end 310 , and the upper end of the fixing bracket 300 is the second end 320 .

[0054] By adopting the above scheme, when the upper end of the fixed bracket 300 is disconnected from the dust bag bracket 110, the fixed bracket 300 can drive the handle bracket 220 to flip downward and switch from the first preset position to the second preset position. In the second preset position, the position of the handle bracket 220 will be adjusted to be set upward or tilted, and correspondingly, the bag opening of the dust bag 210 will also be set upward or tilted. In this way, when the dust bag assembly 200 is detached from the fixed bracket 300 and the box body 100, it can be ensured that the bag opening of the dust bag 210 is facing upward, thereby reducing the risk of dust and other impurities leaking from the bag opening.

[0055] Of course, in other possible implementations, the left end of the fixed bracket 300 can be the first end 310, and the right end of the fixed bracket 300 can be the second end 320; or the right end of the fixed bracket 300 can be the first end 310, and the left end of the fixed bracket 300 can be the second end 320; and so on.

[0056] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, an elastic member (not shown in the figure) is disposed at the connection between the first end 310 of the fixed bracket 300 and the dust bag bracket 110. The elastic member generates elastic compression deformation when the second end 320 of the elastic member is connected to the dust bag bracket 110, so that the elastic member can provide an elastic restoring force for the fixed bracket 300 to rotate and unfold relative to the dust bag bracket 110. The elastic member can be a torsion spring.

[0057] By adopting the above solution, while the fixed bracket 300 drives the dust bag bracket 110 to rotate from the second preset position to the first preset position, the elastic member can gradually generate elastic compression deformation and gradually accumulate force; when the second end 320 of the fixed bracket 300 is connected to the dust bag bracket 110, the elastic member can maintain elastic compression deformation and retain elastic restoring force; when the second end 320 of the fixed bracket 300 is disconnected from the dust bag bracket 110, the elastic restoring force of the elastic member can cause the fixed bracket 300 to rotate and unfold relative to the dust bag bracket 110; the use performance is better.

[0058] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, a sliding groove 301 extending in the up-down direction is formed on the upper side of the fixing bracket 300 , and the handle bracket 220 is detachably installed in the sliding groove 301 .

[0059] By adopting the above scheme, the handle bracket 220 can be detachably installed on the fixed bracket 300 by sliding in the sliding groove 301. Based on this, the disassembly convenience between the handle bracket 220 and the fixed bracket 300 can be guaranteed and improved, and the alignment accuracy of the handle bracket 220 and the fixed bracket 300 after installation can be guaranteed and improved, which can facilitate the handle bracket 220 to be accurately docked with the dust bag bracket 110 when the fixed bracket 300 is connected to the dust bag bracket 110.

[0060] See also Figure 2 , Figure 3 , Figure 4 In this embodiment, a detection sensor 500 is disposed on the dust bag bracket 110 , and a trigger structure 223 for triggering the detection sensor 500 is disposed on the handle bracket 220 .

[0061] In a possible implementation, the detection sensor 500 can be used to detect whether the dust bag assembly 200 is installed in place. Specifically, when the dust bag assembly 200 is not installed in the box 100, or the handle bracket 220 has not reached the first preset position, the trigger structure 223 of the handle bracket 220 will not trigger the detection sensor 500. At this time, the controller (not shown in the figure) can obtain a signal that the detection sensor 500 is in an untriggered state, determine that the dust bag assembly 200 is not installed in place, and continue to limit the dust collection device from working until the dust bag assembly 200 is installed in the box 100 and the fixed bracket 300 drives the handle bracket 220 to rotate to the first preset position. On the contrary, when the dust bag assembly 200 is installed in the box body 100 and the fixed bracket 300 drives the handle bracket 220 to rotate to the first preset position, the trigger structure 223 of the handle bracket 220 can directly trigger the detection sensor 500, or push the push member 600 to move and trigger the detection sensor 500 with the help of the push member 600. At this time, the controller can obtain a signal that the detection sensor 500 is in a triggered state, determine that the dust bag assembly 200 is installed in place, and release the restriction on the operation of the dust collection device, that is, allow the dust collection device to work or suspend work as needed.

[0062] In another possible implementation ( Figure 4In the scheme shown in the figure), the detection sensor 500 can be used to detect whether the dust bag assembly 200 is in place and whether the box cover covers the box body 100. Specifically, when the dust bag assembly 200 is installed on the box body 100 and the fixed bracket 300 drives the handle bracket 220 to rotate to the first preset position, the trigger structure 223 of the handle bracket 220 can push the push member 600 from the initial position to the preparatory position, and then the box cover is closed with the box body 100. At this time, the box cover can continue to push the push member 600 from the preparatory position to the trigger position. The push member 600 can trigger the detection sensor 500 only at the trigger position. Then, the controller can obtain a signal that the detection sensor 500 is in a triggered state, determine that the dust bag assembly 200 is installed in place and the box cover covers the box body 100, and release the restriction on the dust collection device to work, allowing the dust collection device to work or suspend work as needed. On the contrary, when the dust bag assembly 200 is not installed on the box body 100, or the fixed bracket 300 does not drive the handle bracket 220 to rotate to the first preset position, or the box cover is open to the box body 100, the push member 600 cannot trigger the detection sensor 500. At this time, the controller can obtain a signal that the detection sensor 500 is in an untriggered state, and determine that the dust bag assembly 200 is not installed in place or the box cover is not closed, and continue to limit the operation of the dust collection device until the dust bag assembly 200 is installed in place and the box cover is closed to the box body 100.

[0063] The detection sensor 500 may be a Hall sensor, a push button switch, a rocker switch, a toggle switch, or the like, which is not limited in this embodiment.

[0064] See also Figure 3 , Figure 4 , Figure 6 , an embodiment of the present invention also provides a cleaning robot system, including a cleaning robot and a dust collecting device.

[0065] 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, etc. When the cleaning robot is working, it can clean impurities such as dust, hair or paper scraps in the cleaning area and store them in the garbage storage cavity inside it. After working for a period of time, the cleaning robot can move to the dust collection device and dock its dust discharge port with the dust suction port of the dust collection device. Then, the dust collection device works to generate airflow and drive the impurities in the garbage storage cavity along the dust inlet channel 120 and the ventilation pipe 111 into the dust bag 210, thereby completing the transfer and collection of impurities.

[0066] Embodiment 2

[0067] The difference between this embodiment and the first embodiment is that:

[0068] Please refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, the ventilation tube 111 is an elastic tube.

[0069] By adopting the above scheme, when the ventilation pipe 111 and the ventilation hole 221 are aligned and plugged in, the ventilation pipe 111 can seal the gap between the ventilation pipe 111 and the ventilation hole 221 through circumferential rebound. Based on this, the sealing effect between the ventilation hole 221 and the ventilation pipe 111 can be guaranteed and improved to reduce the risk of ash leakage from the gap between the ventilation hole 221 and the ventilation pipe 111.

[0070] Please refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, an elastic sealing ring 222 is provided on the inner edge of the vent hole 221, and the elastic sealing ring 222 is sealed and fitted with the peripheral side of the vent pipe 111; the vent pipe 111 is an elastic tube.

[0071] By adopting the above scheme, when the ventilation pipe 111 and the ventilation hole 221 are aligned and plugged in, the ventilation pipe 111 can be sealed with the ventilation hole 221 through circumferential rebound. At the same time, the elastic sealing ring 222 on the inner edge of the ventilation hole 221 can also elastically press against the circumference of the ventilation pipe 111 to form a seal. Based on this, the two sealing lines can be used to reliably ensure and improve the sealing effect between the ventilation hole 221 and the ventilation pipe 111, so as to reduce the risk of dust leakage from the gap between the ventilation hole 221 and the ventilation pipe 111.

[0072] Embodiment 3

[0073] The difference between this embodiment and the first embodiment is that:

[0074] Please refer to Figure 1 , Figure 2 , Figure 3 In this embodiment, the fixing bracket 300 has a first end 310 and a second end 320 opposite to each other, and the first end 310 and the second end 320 are both detachably connected to the dust bag bracket 110 .

[0075] Specifically, when the dust bag assembly 200 is installed on the box 100, the handle bracket 220 can be installed on the fixed bracket 300, and then the opposite ends of the fixed bracket 300 are connected to the dust bag bracket 110, so that the handle bracket 220 and the dust bag bracket 110 are accurately aligned and docked, and the installation effect of the handle bracket 220 is stabilized.

[0076] On the contrary, the connection between the two opposite ends of the fixing bracket 300 and the dust bag bracket 110 can be released first, and then the handle bracket 220 can be removed from the fixing bracket 300 to facilitate the removal of the dust bag assembly 200 from the box 100.

[0077] The two opposite ends of the fixing bracket 300 may be optionally snap-connected with the dust bag bracket 110 .

[0078] Embodiment 4

[0079] The difference between this embodiment and the first embodiment is that:

[0080] Please refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, a detection sensor 500 is provided on the dust bag bracket 110; a movable trigger structure 223 is provided on the fixed bracket 300. When the handle bracket 220 is installed on the fixed bracket 300, the trigger structure 223 is supported by the handle bracket 220 and moves to a preset protruding position to trigger the detection sensor; when the handle bracket 220 is separated from the fixed bracket 300, the trigger structure 223 loses the support of the handle bracket 220 and automatically returns to a preset retracted position to avoid triggering the detection sensor.

[0081] In a possible implementation, the detection sensor 500 can be used to detect whether the dust bag assembly 200 is installed in place. Specifically, when the dust bag assembly 200 is installed in the box 100 and the handle bracket 220 is installed in the sliding groove 301 of the fixed bracket 300, the trigger structure 223 can be pushed by the handle bracket 220 and move to a preset protruding position. Then, the fixed bracket 300 drives the handle bracket 220 to rotate to the first preset position, and the protruding trigger structure 223 can directly trigger the detection sensor 500, or push the push member 600 to move and trigger the detection sensor 500 with the help of the push member 600. At this time, the controller can obtain a signal that the detection sensor 500 is in a triggered state, determine that the dust bag assembly 200 is installed in place, and release the restriction on the dust collection device, that is, allow the dust collection device to work or suspend work as needed. On the contrary, when the dust bag assembly 200 is not installed on the box body 100, or the dust bag assembly 200 is installed on the box body 100 but the handle bracket 220 is not installed on the sliding groove 301, the trigger structure 223 can automatically return to the preset retracted position. At this time, even if the fixed bracket 300 is rotated to the first preset position, the retracted trigger structure 223 will not trigger the detection sensor 500. At this time, the controller can obtain a signal that the detection sensor 500 is in an untriggered state, determine that the dust bag assembly 200 is not installed in place, and continue to limit the operation of the dust collection device during this period.

[0082] In another possible embodiment, the detection sensor 500 can be used to detect whether the dust bag assembly 200 is in place and whether the box cover covers the box body 100. Specifically, when the dust bag assembly 200 is installed on the box body 100 and the handle bracket 220 is installed in the sliding groove 301 of the fixed bracket 300, the trigger structure 223 is pushed by the handle bracket 220 and moves to a preset protruding position. Then, the fixed bracket 300 drives the handle bracket 220 to rotate to the first preset position, and the extended trigger structure 223 can push the push member 600 from the initial position to the preparatory position. Then, the box cover is closed with the box body 100, and the box cover can continue to push the push member 600 from the preparatory position to the trigger position. The push member 600 can trigger the detection sensor 500 only at the trigger position. At this time, the controller can obtain a signal that the detection sensor 500 is in a triggered state, determine that the dust bag assembly 200 is installed in place and the box cover covers the box body 100, and release the restriction on the dust collection device to work, allowing the dust collection device to work or suspend work as needed. On the contrary, when the dust bag assembly 200 is not installed on the box body 100, or the dust bag assembly 200 is installed on the box body 100 but the handle bracket 220 is not installed in the sliding groove 301, or the fixed bracket 300 does not drive the handle bracket 220 to rotate to the first preset position, or the box cover is open to the box body 100, the push member 600 cannot trigger the detection sensor 500. At this time, the controller can obtain a signal that the detection sensor 500 is in an untriggered state, determine that the dust bag assembly 200 is not installed in place or the box cover is not closed, and continue to limit the operation of the dust collection device until the dust bag assembly 200 is installed in place and the box cover is closed to the box body 100.

[0083] In some implementations, the detection sensor 500 may be a Hall sensor, a push button switch, a rocker switch, a toggle switch, or the like, which is not limited in this embodiment.

[0084] Of course, in other possible embodiments, the dust bag bracket 110 is provided with a detection sensor 500, and the fixed bracket 300 is provided with a trigger structure 223 that is immovable and used to trigger the detection sensor 500. The effect and principle of the trigger structure 223 provided on the fixed bracket 300 of this embodiment can refer to the effect and principle of the trigger structure 223 provided on the handle bracket 220 of the first embodiment, and this embodiment will not be described in detail here.

[0085] Embodiment 5

[0086] The difference between this embodiment and the first embodiment is that:

[0087] Please refer to Figure 2 In this embodiment, the handle bracket 220 is detachably mounted on a side of the fixing bracket 300 facing the dust bag bracket 110 .

[0088] By adopting the above solution, the handle bracket 220 can be first connected to the dust bag bracket 110, and then the handle bracket 220 can be pressed between the fixed bracket 300 and the dust bag bracket 110 through the fixed bracket 300. In this way, the convenience of disassembly and assembly of the handle bracket 220 can be guaranteed and improved, and the stability of the handle bracket 220 after installation can be guaranteed and improved.

[0089] 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.
