Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to a dust box, cleaning equipment, and cleaning system. Background Technology

[0002] As people's living standards improve, cleaning equipment that can automatically clean itself is gradually entering people's homes.

[0003] To reduce manual intervention during the cleaning process, a cleaning equipment base station is installed to clean the equipment. However, during operation, hair, fibers, and other debris can easily clog HEPA (High Efficiency Particulate Air) filters and filter cotton. The base station struggles to remove this debris during automatic cleaning, requiring frequent manual cleaning of the filters. Utility Model Content

[0004] This application provides a dust box, cleaning equipment, and cleaning system to reduce the frequency of manual cleaning of filter elements.

[0005] To address the aforementioned technical problems, the first aspect of this application provides a dust box for cleaning equipment, comprising a box body and a separation structure; the box body has a dust removal inlet and an air duct outlet, the dust removal inlet being connected to the dust suction channel of the cleaning equipment, and the air duct outlet being connected to the first suction mechanism of the cleaning equipment; a dust storage space is formed inside the box body; the separation structure is disposed inside the box body; the separation structure includes a separation inlet, a separation airflow outlet, and a separation debris outlet that are interconnected, the separation inlet being connected to the dust removal inlet, the separation airflow outlet being connected to the air duct outlet, and the separation debris outlet being connected to the dust storage space.

[0006] The beneficial effects of this application are: by rationally setting the internal structure of the dust box, the separation structure is integrated into the dust box. The separation structure can separate air and garbage, greatly reducing the garbage content and particle size in the airflow flowing out of the separation airflow outlet. For example, garbage such as hair and cotton wool will basically not adhere to the surface of the filter element (the filter element is set on the airflow path from the separation airflow outlet to the duct outlet), thereby extending the cycle of garbage clogging the filter element upstream of the duct outlet, reducing the frequency of manual cleaning of the filter element, extending the cleaning cycle, and also helping to increase the service life of the filter element.

[0007] Based on the above technical solution, the following improvements can be made to this application.

[0008] Furthermore, the box body includes a main body and a top cover, with the top cover covering the end of the main body; the air duct outlet is located on the top cover; the separation structure includes a first separation part and a second separation part; the two opposite ends of the first separation part abut against the main body and the top cover respectively; the two opposite ends of the second separation part abut against the main body and the top cover respectively; the first separation part forms an accommodating space; the second separation part is disposed within the accommodating space, and the second separation part is spaced apart from the first separation part; the second separation part surrounds and forms a cavity; an annular space is defined between the first separation part and the second separation part; a debris separation outlet is provided at the end of the first separation part near the top cover; a separation inlet is provided at the end of the first separation part near the main body; a through hole is provided on the side wall of the second separation part; the port of the second separation part near the top cover is a separation airflow outlet.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: By setting a debris separation outlet at the end of the first separation section near the top cover (i.e., a debris separation outlet is set at the top of the first separation section), and a separation inlet at the end of the first separation section near the main body (i.e., a separation inlet is set at the bottom of the first separation section), the airflow carrying debris entering from the separation inlet undergoes a spiral upward circular motion within the space defined between the first and second separation sections. Using inertia, larger and more massive debris in the airflow is thrown out from the debris separation outlet into the ash storage space. The remaining smaller and lighter debris, which cannot be separated, passes through the through-hole of the second separation section along with the airflow into the cavity of the second separation section, and then flows out from the port of the second separation section near the top cover (i.e., the separation airflow outlet). The separation structure uses inertia to separate debris in the airflow, resulting in low resistance. This allows the cleaning equipment to maintain a large suction force and a good separation effect, with a separation efficiency of over 95%.

[0010] Furthermore, the separation structure also includes a guide section, the inner edge of which is connected to the second separation section, and the outer edge of which is connected to the first separation section; and the guide section is spirally arranged along the axial direction of the second separation section starting from the separation inlet.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a guide section, the guide section guides the airflow entering from the separation inlet to spiral upward, which is conducive to the large mass and large volume of garbage in the airflow being thrown out from the separation debris outlet at the top of the first separation section to the ash storage space, thus achieving a good separation effect.

[0012] Furthermore, the end of the guide portion away from the separation inlet is rotated 360°-390° relative to the end of the guide portion near the separation inlet; the end of the guide portion away from the separation inlet covers the separation inlet.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting the guide part as described above, the guide part rotates one or more times, avoiding multiple rotations of the guide part, and forming a relatively small space between adjacent two rotations, which hinders the upward spiraling out of the garbage, and the separation structure can achieve a good separation effect.

[0014] Furthermore, the portion of the second separation section that is higher than the guide section is provided with a through hole.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the above-mentioned arrangement prevents the airflow entering from the separation inlet from directly impacting the through hole of the second separation section, reduces the amount of unseparated airflow that flows directly through the through hole, helps to extend the cycle of the filter element upstream of the garbage blockage air duct outlet, reduces the frequency of manual cleaning of the filter element, and extends the cleaning cycle.

[0016] Furthermore, the first separation part is a cylindrical structure, and the second separation part is a cylindrical structure or a frustum structure, with the first separation part and the second separation part being coaxially arranged.

[0017] The beneficial effects of adopting the above-mentioned further scheme are: through the above setting, the airflow entering from the separation inlet is kept in a spiral upward circular motion between the first separation section and the second separation section, and the garbage in the airflow can be thrown out from the separation debris outlet by using inertia; the resistance of separation by inertia is relatively small, which is conducive to improving the separation efficiency.

[0018] Furthermore, the ash storage space includes multiple sub-ash storage spaces, which are arranged around the separation structure; the separation structure includes multiple separation debris outlets; one sub-ash storage space is connected to at least one separation debris outlet; the box has multiple dust collection inlets and several dust collection outlets; the dust collection inlets are used to allow airflow from outside the box to enter the box, and the dust collection outlets are used to connect to the second suction mechanism of the cleaning equipment base station; one sub-ash storage space is connected to at least one dust collection outlet and at least one dust collection inlet.

[0019] The beneficial effects of adopting the above-mentioned further solution are as follows: By setting the ash storage space to include multiple sub-ash storage spaces, which are arranged around the separation structure, and each sub-ash storage space is connected to at least one separation debris outlet, the ash storage space maintains the collection of waste separated by the separation structure. By setting one sub-ash storage space to be connected to at least one dust collection inlet and at least one dust collection outlet, after the second suction mechanism of the cleaning equipment base station is activated, the airflow passes through each sub-ash storage space, maintaining a good collection effect of waste in each sub-ash storage space.

[0020] Furthermore, the separation structure is located in the middle of the box; the ash storage space includes two sub-ash storage spaces located on opposite sides of the separation structure.

[0021] The beneficial effects of adopting the above-mentioned further solutions are: the dust box has a simple structure and maintains efficient dust collection.

[0022] Furthermore, a first one-way plate is provided at the dust collection outlet, and a second one-way plate is provided at the dust collection inlet. The first and second one-way plates are configured to open when the second suction mechanism is activated.

[0023] The beneficial effect of adopting the above-mentioned further solution is that by setting a first one-way plate at the dust collection outlet and a second one-way plate at the dust collection inlet, the first and second one-way plates are only opened during the dust collection stage. This reduces the leakage of garbage from the dust collection inlet and / or dust collection outlet in the ash storage space after the dust removal stage has ended and before the dust has been collected by the cleaning equipment base station, thus maintaining the effectiveness of the cleaning equipment.

[0024] A second aspect of this application provides a cleaning device, including a body and a dust box; the body includes a first suction mechanism and a dust box mounting slot; the dust box is disposed in the dust box mounting slot; the dust box is the aforementioned dust box, and the air duct outlet of the dust box is connected to the first suction mechanism.

[0025] Cleaning equipment base stations have at least the same advantages as dust boxes.

[0026] A third aspect of this application provides a cleaning system, including a cleaning device and a cleaning device base station; the cleaning device is the aforementioned cleaning device; the cleaning device includes a first connecting part; the cleaning device base station includes a second connecting part and a second suction mechanism; the second connecting part is connected to the first connecting part; the second suction mechanism is connected to the dust collection outlet of the dust box of the cleaning device.

[0027] Cleaning systems offer at least the same advantages as cleaning equipment.

[0028] Furthermore, the cleaning equipment includes a first controller, which controls the second one-way plate of the dust box to open after a preset time has elapsed since the second suction mechanism has started.

[0029] The beneficial effect of adopting the above-mentioned further solution is that the opening and closing of the second one-way plate is controlled by the first controller of the cleaning equipment. Before the second one-way plate is opened, the residual garbage in the separation structure can be quickly sucked into the cleaning equipment base station to maintain a good dust collection effect.

[0030] Furthermore, the cleaning equipment base station includes a second controller, which controls the second suction mechanism to start and gradually increases the power of the second suction mechanism to a preset power; the second one-way plate of the dust box opens under the preset power of the second suction mechanism.

[0031] The beneficial effect of adopting the above-mentioned further solution is that by adjusting the power of the second suction mechanism to control the opening and closing of the second one-way plate, the residual garbage in the separation structure can be quickly sucked into the cleaning equipment base station before the second one-way plate opens, thus maintaining a good dust collection effect.

[0047] With the development of the cleaning equipment industry and the increasing demands of consumers for automation in cleaning equipment, the level of intelligence in cleaning equipment on the market is becoming increasingly higher. For example, cleaning equipment is equipped with a cleaning equipment base station, which is used to clean the equipment, reducing manual intervention during the cleaning process.

[0048] During operation, the HEPA (High Efficiency Particulate Air) filter and filter cotton are easily clogged by small particles, resulting in a significant decrease in the suction power of the cleaning equipment. Furthermore, the cleaning equipment base station cannot automatically clean the debris on the filter, requiring frequent manual cleaning of the filter.

[0049] In view of this, this application provides a dust box, cleaning equipment, and cleaning system to reduce the frequency of manual cleaning of filter elements and extend the cleaning cycle.

[0051] The dust box 1 provided in this embodiment is used for cleaning equipment. The structure of the cleaning equipment other than the dust box 1 can be found in the prior art.

[0052] The dust box 1 provided in this embodiment includes a box body 10 and a separation structure 20.

[0053] The housing 10 has a dust inlet 101, an air duct outlet 102, a dust collection inlet 103, and a dust collection outlet 104. The dust inlet 101 is connected to the suction channel of the cleaning equipment, the air duct outlet 102 is connected to the first suction mechanism of the cleaning equipment, the dust collection inlet 103 allows airflow from outside the housing 10 to enter the housing 10, and the dust collection outlet 104 is connected to the second suction mechanism of the cleaning equipment base station. The housing 10 forms a dust storage space 105; the dust storage space 105 is connected to the dust collection inlet 103 and the dust collection outlet 104. It should be noted that the dust collection inlet 103 and the dust collection outlet 104 on the housing 10 are optional structures, and whether or not to provide the dust collection inlet 103 and the dust collection outlet 104 can be selected as needed.

[0054] The separation structure 20 is disposed inside the housing 10. The separation structure 20 includes a separation inlet 201, a separation airflow outlet 202 and a separation debris outlet 203 that are interconnected. The separation inlet 201 is connected to the dust removal inlet 101, the separation airflow outlet 202 is connected to the air duct outlet 102, and the separation debris outlet 203 is connected to the ash storage space 105.

[0055] When the dust box 1 is applied to the cleaning equipment and the cleaning equipment is in operation (i.e., in the dust removal stage), the first suction mechanism of the cleaning equipment is activated, generating a large suction force to draw the airflow from outside the cleaning equipment, carrying debris (including dust), into the dust collection channel of the cleaning equipment, and then into the dust removal inlet 101 connected to the dust collection channel. The airflow carrying debris entering from the dust removal inlet 101 flows through the separation inlet 201 and enters the separation structure 20. The separation structure 20 is used to separate the airflow carrying debris; the debris separated by the separation structure 20 enters the dust storage space 105 connected to the separation debris outlet 203 from the separation debris outlet 203; the airflow separated by the separation structure 20 enters the air duct outlet 102 connected to the separation airflow outlet 202 from the separation airflow outlet 202. It can be understood that when the cleaning equipment is in operation, the path of the airflow carrying the garbage in the dust box 1 is as follows: the airflow goes from the dust removal inlet 101 to the separation inlet 201 to the separation airflow outlet 202 to the air duct outlet 102; among which, the garbage is thrown out from the separation debris outlet 203 of the separation structure 20 to the ash storage space 105.

[0056] When the cleaning equipment base station is cleaning the cleaning equipment (i.e., the dust collection stage), the second suction mechanism of the cleaning equipment base station is activated, generating a large suction force. The cleaning equipment base station cleans the dust collection space 105, which is connected to the dust collection outlet 104, through the dust collection outlet 104. It can be understood that when the cleaning equipment base station is automatically cleaning the cleaning equipment, the airflow path in the dust box 1 is: airflow from the dust collection inlet 103 - dust collection space 105 - dust collection outlet 104; wherein, during the airflow through the dust collection space 105, the airflow sucks the garbage in the dust collection space 105 into the cleaning equipment base station.

[0057] It should be noted that the dust collection stage is divided into two phases. In the first phase, the dust collection outlet 104 is opened and connected to the second suction mechanism of the cleaning equipment base station. Since the power of the second suction mechanism is relatively large, generally several times or even tens of times that of the first suction mechanism, while sucking up the garbage in the ash storage space 105, the garbage remaining in the separation structure 20 can be sucked into the cleaning equipment base station through the separation debris outlet 203. In the second stage, the dust collection inlet 103 opens, and the airflow has two paths. The first path is from the dust collection inlet 103 to the ash storage space 105 and then to the dust collection outlet 104. The second path is from the dust removal inlet 101 to the separation inlet 201 to the separated debris outlet 203, then back to the ash storage space 105 and finally to the dust collection outlet 104. The second path is more complex and has greater resistance than the first path. Therefore, after the dust collection inlet 103 opens, most of the airflow flows from the first path to the dust collection outlet 104, while a small portion flows from the second path, ensuring that almost all the debris in the ash storage space 105 is sucked into the cleaning equipment base station. The first stage is relatively short.

[0058] In this embodiment of the application, by designing the internal structure of the dust box 1 as described above, a dual air duct is formed inside the dust box 1, which is the airflow path of the dust removal stage and the airflow path of the dust collection stage. The airflow path of the dust removal stage and the airflow path of the dust collection stage do not interfere with each other, and at the same time, the dust collection efficiency is greatly improved.

[0059] In this embodiment, by rationally configuring the internal structure of the dust box 1, the separation structure 20 is integrated within the dust box 1. The separation structure 20 can separate air and waste, greatly reducing the content and particle size of waste in the airflow exiting the separation airflow outlet 202. For example, hair, lint, and other waste will not adhere to the surface of the filter element (the filter element is set on the airflow path from the separation airflow outlet 202 to the duct outlet 102), thereby extending the cycle of waste clogging the filter element upstream of the duct outlet 102, reducing the frequency of manual cleaning of the filter element, extending the cleaning cycle, and also helping to increase the service life of the filter element. At the same time, the cleaning equipment base station can automatically clean the waste in the ash storage space 105 through the dust collection outlet 104, improving the user experience.

[0060] By setting the separation structure 20 inside the box 10, the space utilization rate is high and there are no requirements for the structural layout of the cleaning equipment. By replacing the dust box of the existing cleaning equipment with the dust box 1 provided in this embodiment, the effect of extending the cleaning cycle of the filter can be achieved.

[0061] In one embodiment, a filter element is provided along the flow path between the separated airflow outlet 202 and the duct outlet 102. The filter element further filters lighter and smaller particles of debris from the airflow exiting the separated airflow outlet 202. That is, the airflow exiting the separated airflow outlet 202 flows through the filter element and then through the duct outlet 102. Optionally, the filter element can be a HEPA (High Efficiency Particulate Air) filter.

[0062] In one implementation, such as Figure 1 As shown, the box body 10 includes a main body 110 and a top cover 120, with the top cover 120 covering the end of the main body 110. An air duct outlet 102 is disposed on the top cover 120.

[0063] like Figure 3 , Figure 5As shown, the separation structure 20 includes a first separation portion 210 and a second separation portion 220. The two opposite ends of the first separation portion 210 abut against the main body 110 and the upper cover 120, respectively. The two opposite ends of the second separation portion 220 abut against the main body 110 and the upper cover 120, respectively. The first separation portion 210 forms an accommodating space 210a, and the second separation portion 220 is disposed within the accommodating space 210a, spaced apart from the first separation portion 210. An annular space is defined between the first separation portion 210 and the second separation portion 220. The second separation portion 220 encloses a cavity 220a. A debris separation outlet 203 is provided at the end of the first separation portion 210 near the upper cover 120; a separation inlet 201 is provided at the end of the first separation portion 210 near the main body 110. A through hole 220b is provided on the side wall of the second separation portion 220. The port of the second separation portion 220 near the upper cover is a separation airflow outlet 202.

[0064] By setting a separation outlet 203 at the end of the first separation section 210 near the top cover 120 (i.e., the top of the first separation section 210 has a separation outlet 203), and a separation inlet 201 at the end of the first separation section 210 near the main body 110 (i.e., the bottom of the first separation section 210 has a separation inlet 201), the airflow carrying garbage entering from the separation inlet 201 performs a spiral upward circular motion within the space defined between the first separation section 210 and the second separation section 220. Using inertia, the larger and more massive garbage in the airflow is thrown out from the separation outlet 203 to the ash storage space 105. The remaining smaller and lighter garbage that cannot be separated passes through the through hole 220b of the second separation section 220 along with the airflow and enters the cavity 220a of the second separation section 220, and then flows out from the port of the second separation section 220 near the top cover 120 (i.e., the separation airflow outlet 202). The separation structure 20 utilizes inertia to separate debris from the airflow, resulting in low resistance. This allows the cleaning equipment to maintain a high suction power and excellent separation effect, with a separation efficiency exceeding 95%. Compared to the multi-cone first separation section, the separation resistance of the separation structure 20 is significantly lower.

[0065] In one embodiment, the top cover 120 includes a flow channel and a filter disposed thereon, the flow channel being a channel that connects the separated airflow outlet 202 with the air duct outlet 102. The end of the second separating portion 220 near the top cover 120 abuts against the filter, so that the airflow flowing out from the port of the second separating portion 220 near the top cover 120 (i.e., the separated airflow outlet 202) flows through the filter to the air duct outlet 102.

[0066] In one implementation, such as Figure 3As shown, the first separation part 210 has a cylindrical structure, and the second separation part 220 has a cylindrical structure or a frustum structure. The first separation part 210 and the second separation part 220 are coaxially arranged.

[0067] With the above settings, the airflow entering from the separation inlet 201 is kept in a spiral upward circular motion between the first separation section 210 and the second separation section 220. The inertia can be used to throw the garbage in the airflow out of the separation debris outlet 203. The resistance of separation by inertia is relatively small, which is conducive to improving the separation efficiency.

[0068] Optionally, the second separation section 220 has a frustum structure, with the diameter of the frustum structure gradually decreasing along the direction from the main body 110 to the upper cover 120. With the above arrangement, when it is necessary to remove the upper cover 120 to clean the surface of the tube wall of the second separation section 220 near the first separation section 210, it is convenient to clean the debris on the surface of the first separation section 210.

[0069] In one implementation, such as Figure 3 As shown, a notch is formed on the end face of the first separation section 210 near the upper cover 120, and the notch cooperates with the upper cover 120 to form a separation debris outlet 203. With the above arrangement, the formation structure of the separation debris outlet 203 is simple, which helps to reduce the processing difficulty of the separation structure 20.

[0070] In one implementation, such as Figure 3 As shown, the dust removal inlet 101 is located on the main body 110. Since the separation inlet 201 of the separation structure 20 is located at the end of the first separation part 210 near the main body 110, placing the dust removal inlet 101 on the main body 110 can shorten the path between the dust removal inlet 101 and the separation inlet 201. Optionally, the dust removal inlet 101 is located on the side wall of the main body 110.

[0071] In one implementation, such as Figure 5 As shown, a portion of the side wall of the main body 110 is shared with a portion of the side wall of the first separation section 210 near the end of the main body 110. An opening is provided on this shared side wall, which serves as both a dust collection inlet 101 and a separation inlet 201. With the above arrangement, the structure is simple and the space utilization rate is high.

[0072] In one implementation, such as Figure 5 As shown, the separation structure 20 also includes a guide portion 230, the inner edge of which is connected to the second separation portion 220, and the outer edge of which is connected to the first separation portion 210; and the guide portion 230 is spirally arranged along the axial direction of the second separation portion 220 starting from the separation inlet 201.

[0073] By setting the guide section 230, the guide section 230 guides the airflow entering from the separation inlet 201 to spiral upward, which is conducive to the large mass and large volume of waste in the airflow being thrown out from the separation debris outlet 203 at the top of the first separation section 210 to the ash storage space 105, thus achieving a good separation effect.

[0074] In one implementation, such as Figure 5 As shown, the end of the guide portion 230 away from the separation inlet 201 is rotated 360°-390° relative to the end of the guide portion 230 near the separation inlet 201; the end of the guide portion 230 away from the separation inlet 201 covers the separation inlet 201.

[0075] By configuring the guide section 230 as described above, the guide section 230 rotates one revolution or slightly more than one revolution, avoiding multiple revolutions of the guide section 230. This creates a relatively small space between adjacent revolutions, hindering the upward spiral ejection of waste, and the separation structure 20 can achieve a good separation effect.

[0076] In one implementation, such as Figure 5 As shown, the portion of the second separation section 220 above the guide section 230 is provided with a through hole 220b. This arrangement prevents the airflow entering from the separation inlet 201 from directly impacting the through hole 220b of the second separation section 220, reducing the amount of unseparated airflow flowing directly through the through hole 220b. This helps to extend the cycle of the filter element upstream of the air duct outlet 102, reducing the frequency of manual cleaning of the filter element and extending the cleaning cycle.

[0077] In one implementation, such as Figure 3 and Figure 5 As shown, the ash storage space 105 includes multiple sub-ash storage spaces 105a, which are arranged around the separation structure 20. The separation structure 20 includes multiple separation debris outlets 203; one sub-ash storage space 105a communicates with at least one separation debris outlet 203. The housing 10 has multiple dust collection inlets 103 and several dust collection outlets 104. One sub-ash storage space 105a communicates with at least one dust collection outlet 104 and at least one dust collection inlet 103.

[0078] By configuring the ash storage space 105 to include multiple sub-ash storage spaces 105a, which are arranged around the separation structure 20, and each sub-ash storage space 105a is connected to at least one separated debris outlet 203, the ash storage space 105 maintains the collection of waste separated by the separation structure 20. By configuring each sub-ash storage space 105a to be connected to at least one dust collection inlet 103 and at least one dust collection outlet 104, after the second suction mechanism of the cleaning equipment base station is activated, the airflow passes through each sub-ash storage space 105a, maintaining a good collection effect of waste in each sub-ash storage space 105a.

[0079] In one embodiment, the dust collection inlet 103 and the dust collection outlet 104, which are connected to the sub-ash storage space 105a, are arranged opposite to each other to keep the airflow path from the dust box inlet 101 to the sub-ash storage space 105a to the dust collection outlet 104 short, which is conducive to efficient dust collection.

[0080] For example, such as Figure 3 and Figure 5 As shown, the separation structure 20 is located in the middle of the housing 10. The dust storage space 105 includes two sub-dust storage spaces 105a located on opposite sides of the separation structure 20. The first separation section 210 of the separation structure 20 forms two separation debris outlets 203, one of which communicates with one sub-dust storage space 105a. The housing 10 has two dust collection inlets 103 and one dust collection outlet 104; one dust collection inlet 103 communicates with one sub-dust storage space 105a, and both sub-dust storage spaces 105a communicate with the same dust collection outlet 104. The dust collection inlets 103 and the dust collection outlet 104 are arranged opposite to each other. With the above arrangement, the dust box 1 has a simple structure and maintains efficient dust collection.

[0081] In one embodiment, the dust collection outlet 104 is provided with a first one-way plate 106, and the dust collection inlet 103 is provided with a second one-way plate 107. The first one-way plate 106 and the second one-way plate 107 are configured to open when the second suction mechanism of the cleaning equipment base station is activated.

[0082] By setting a first one-way plate 106 at the dust collection outlet 104 and a second one-way plate 107 at the dust collection inlet 103, the first one-way plate 106 and the second one-way plate 107 are only opened during the dust collection stage. This reduces the leakage of garbage from the dust collection inlet 103 and / or the dust collection outlet 104 after the dust removal stage has ended and before the dust has been collected by the cleaning equipment base station, thus maintaining the effectiveness of the cleaning equipment.

[0083] In one embodiment, the dust collection inlet 101 is in a normally open state, meaning that a baffle is not required at the dust collection inlet 101. Since the airflow carrying the waste in the separation structure 20 is spiral upward, the separation structure 20 will basically not retain any waste, and therefore there will be virtually no waste leaking out from the dust collection inlet 101. Therefore, the dust collection inlet 101 can be in a normally open state.

[0084] In one embodiment, the first separation part 210 is fixedly connected to the main body 110.

[0085] In one embodiment, the second separation portion 220 is fixedly connected to the main body 110.

[0086] In one embodiment, the second separation part 220 can be a nylon mesh, a metal mesh, or a plastic mesh, and the holes in the mesh structure are through holes 220b.

[0087] In one implementation, such as Figure 1 and Figure 2 As shown, the top cover 120 includes a first sub-top cover 120a, a second sub-top cover 120b, and a flow channel structure 120c. The first sub-top cover 120a is connected to the second sub-top cover 120b and is disposed on the surface of the second sub-top cover 120b away from the main body 110. The flow channel structure 120c is disposed on the side of the second sub-top cover 120b closer to the main body 110. The flow channel structure 120c forms a channel that is at least a portion of the flow channel connecting the separated airflow outlet 202 and the air duct outlet 102.

[0088] In one implementation, such as Figure 3 and Figure 4 As shown, a first limiting member 120a-1 and a second limiting member 120a-2 are provided on the surface of the first sub-cover 120a near the main body 110. Both the first limiting member 120a-1 and the second limiting member 120a-2 are annular structures, with the first limiting member 120a-1 disposed inside the second limiting member 120a-2. The first limiting member 120a-1 abuts against the end face of the second separating part 220. The second limiting member 120a-2 abuts against the end face of the first separating part 210. The first sub-cover 120a, the bottom wall of the main body 110, the first separating part 210, and the second separating part 220 cooperate to define an airflow separation space, in which the airflow spirals upward.

[0089] In one implementation, such as Figure 2 As shown, the main body 110 of the dust box 1 includes a first sub-body 110a and a second sub-body 110b connected to each other, and a first separation part 210 is disposed on the first sub-body 110a.

[0090] In one implementation, such as Figure 1 and Figure 2 As shown, the dust box 1 also includes a first sealing element 30, which is disposed between the main body 110 and the upper cover 120. The sealing element 30 is used to seal the connection surface between the main body 110 and the upper cover 120.

[0091] In one implementation, such as Figure 1 and Figure 2 As shown, the dust box 1 also includes a second seal 40, which is disposed between the first sub-upper cover 120a and the second sub-upper cover 120b. The second seal 40 is used to seal the connection surface between the first sub-upper cover 120a and the second sub-upper cover 120b.

[0092] This application embodiment also provides a cleaning device, which includes a body and a dust box 1. The body includes a first suction mechanism and a dust box mounting slot. The dust box 1 is disposed in the dust box mounting slot. The dust box 1 can be the dust box 1 described in the above embodiments. The air duct outlet 102 of the dust box 1 is connected to the first suction mechanism of the cleaning device.

[0093] In one embodiment, the first suction mechanism is a fan.

[0094] This application also provides a cleaning system, which includes a cleaning device and a cleaning device base station. The cleaning device can be the cleaning device described in the above embodiments. The cleaning device includes a first connecting part. The cleaning device base station includes a second connecting part and a second suction mechanism. The second connecting part is connected to the first connecting part to realize the connection between the cleaning device and the cleaning device base station. The second suction mechanism is connected to the dust collection outlet 104 of the dust box 1 of the cleaning device.

[0095] In one embodiment, the cleaning equipment includes a first controller, which controls the second one-way plate 107 of the dust box 1 to open after a preset time has elapsed since the second suction mechanism of the cleaning equipment base station is activated. For example, when the second suction mechanism is activated, the first one-way plate 106 of the dust box 1 opens, and the second one-way plate 107 is closed, allowing residual waste in the separation structure 20 to be sucked into the ash storage space 105, and then into the cleaning equipment base station. After the second suction mechanism has elapsed for a preset time, the first controller controls the second one-way plate 107 to open. Most of the airflow path is from the dust collection inlet 103 to the sub-ash storage space 105a to the dust collection outlet 104, allowing the waste in the ash storage space 105 to be sucked into the cleaning equipment base station with high efficiency. The period from the activation of the second suction mechanism to its closure is the dust collection stage.

[0096] The opening and closing of the second one-way plate 107 is controlled by the first controller of the cleaning equipment. Before the second one-way plate 107 is opened (i.e., the first stage of the dust collection stage described above), the residual garbage in the separation structure 20 can be quickly sucked into the cleaning equipment base station to maintain a good dust collection effect.

[0097] In one embodiment, the cleaning equipment base station includes a second controller, which controls the second suction mechanism to start and gradually increase its power to a preset power; the second one-way plate 107 of the dust box 1 opens under the preset power of the second suction mechanism. For example, when the power of the second suction mechanism is lower than W1, the second one-way plate 107 is in a closed state, which can suck the residual garbage in the separation structure 20 into the ash storage space 105, and then into the cleaning equipment base station; when the power of the second suction mechanism is higher than W1, the second one-way plate 107 opens under the suction force, and most of the airflow path is dust collection inlet 103-sub-ash storage space 105a-dust collection outlet 104, which can suck the garbage in the ash storage space 105 into the cleaning equipment base station with high efficiency.

[0098] The opening and closing of the second one-way plate 107 is controlled by adjusting the power of the second suction mechanism. Before the second one-way plate 107 is opened (i.e., the first stage of the dust collection stage described above), the residual garbage in the separation structure 20 can be quickly sucked into the cleaning equipment base station to maintain a good dust collection effect.

[0099] In one embodiment, the second suction mechanism is a fan.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
