[0043] Regarding the self-propelled cleaning device 1 described in the embodiment of the cleaning system of this application, please refer to the following content for details.

[0044] As shown in Figures 2 to 5, the self-propelled cleaning device 1 includes a drive wheel 125, a device body 100, and a handheld dust suction device 200, which is detachably connected to the device body 100. The drive wheel 125 is mounted on the device body 100 and is used to drive the device body 100 to move on the work surface. The handheld dust suction device 200 includes a handle 241 and a fan 209. The handheld dust suction device 200 is formed with a dust collection chamber 201, an air inlet 202 and a dust removal port 203 connected to the dust collection chamber 201. The device body 100 is provided with a dust collection port 101, which is connected to the air inlet 202. The fan 209 has an air inlet 2091 connected to the dust collection chamber 201. The fan 209 is used to form an air flow from the dust collection port 101 through the air inlet 202 into the dust collection chamber 201. The dust collection chamber 201 is used to receive garbage objects carried by the air flow. The base station 300 is provided with a dust collecting port 301 . The dust collecting port 301 is used to communicate with the dust removal port 203 , so that garbage objects in the dust collecting chamber 201 can enter the base station 300 through the dust removal port 203 and the dust collecting port 301 .

[0045] After the handheld vacuum cleaner 200 is detached from the main body 100, the handheld vacuum cleaner 200 can be used by the user to collect waste. Specifically, after being detached from the main body 100, the handheld vacuum cleaner 200 can generate an airflow into the handheld vacuum cleaner 200 through the air inlet 202 during operation, thereby transporting waste carried by the airflow through the air inlet 202 to the dust collection chamber 201.

[0046] When the handheld vacuum cleaner 200 is mounted on the device body 100, the handheld vacuum cleaner 200 and the device body 100 can cooperate to collect waste. Specifically, when the handheld vacuum cleaner 200 is mounted on the device body 100, the suction port 101 is connected to the air inlet 202. When the handheld vacuum cleaner 200 is in operation, an airflow is generated from the suction port 101 through the air inlet 202 into the handheld vacuum cleaner 200. The airflow then transports waste carried by the airflow through the suction port 101 and the air inlet 202 to the dust collection chamber 201.

[0047] In some embodiments, when the handheld vacuum cleaner 200 and the device body 100 are both in working condition, the formed airflow can enter the interior of the device body 100 from the suction port 101, and then flow into the handheld vacuum cleaner 200 through the air inlet 202 and transport the garbage objects carried by the airflow to the dust collecting chamber 201.

[0048] As shown in Figures 3 to 6, the dust removal port 203 can be spaced apart from the air inlet 202. The dust removal port 203 is used to connect with the dust collection port 301 of the base station 300 when the self-propelled cleaning equipment 1 and the base station 300 are docked, so that garbage objects in the dust collecting chamber 201 can be sucked into the base station 300 through the dust removal port 203 and the dust collection port 301.

[0049] In some embodiments, the dust collection port 301 is connected to the dust removal port 203 by docking.

[0050] Optionally, as shown in Figures 3 to 6, the device body 100 is provided with a dust outlet 102 that is connected to the dust suction port 101. The dust outlet 102 is configured to be connected to the air inlet 202 when the handheld dust suction device 200 is mounted on the device body 100. Furthermore, the dust outlet 102 is configured to dock with and connect to the air inlet 202 when the handheld dust suction device 200 is mounted on the device body 100.

[0051] When the handheld vacuum cleaner 200 is assembled on the device body 100, the airflow generated when the handheld vacuum cleaner 200 is working can enter the interior of the device body 100 from the vacuum port 101, then flow out from the dust outlet 102, and flow into the dust collecting chamber 201 in the handheld vacuum cleaner 200 through the air inlet 202 and transport the garbage objects carried by the airflow to the dust collecting chamber 201 to achieve the cleaning function.

[0052] Optionally, as shown in FIG3 , the device body 100 is provided with a dust exhaust port 103 and a dust inlet 104 that are interconnected. The dust exhaust port 103 is configured to communicate with the dust collection port 301, and the dust inlet 104 is configured to communicate with the dust removal port 203. Furthermore, the dust exhaust port 103 is configured to dock with and communicate with the dust collection port 301, and the dust inlet 104 is configured to dock with and communicate with the dust removal port 203.

[0053] When the handheld vacuum cleaner 200 is mounted on the device body 100 and the base station 300 is collecting dust, the airflow generated by the base station 300 can flow into the dust collection chamber 201 through the dust suction port 101 and the air inlet 202 in sequence, then leave the dust collection chamber 201 through the dust removal port 203 and enter the device body 100 through the dust inlet 104, and then enter the base station 300 through the dust discharge port 103 and the dust collection port 301. The airflow is used to carry the garbage in the dust collection chamber 201 as it flows through the dust collection chamber 201, thereby collecting the garbage in the dust collection chamber 201 into the base station 300.

[0054] By arranging the dust exhaust port 103 on the device body 100 , the compatibility of the base station 300 with different self-propelled cleaning devices 1 can be improved.

[0055] Optionally, as shown in Figures 2 and 4, the handheld dust collection device 200 is provided with a shielding member 210, which is movably provided at the dust removal port 203 so as to be switchable between a closed position and an open position relative to the dust removal port 203. The shielding member 210 is configured to cover the dust removal port 203 in the closed position, and is also configured to be attracted by the dust collection fan 320 and move from the closed position to the open position to open the dust removal port 203.

[0056] When the self-propelled cleaning device 1 is performing cleaning operations or the handheld vacuum cleaner 200 is removed from the device body 100 and held for cleaning operations, the shield 210 can be in the closed position to cover the dust removal port 203. When the self-propelled cleaning device 1 needs to collect dust, the suction force of the dust collection blower 320 can move the shield 210 to the open position to open the dust removal port 203. The airflow generated by the dust collection blower 320 can carry garbage objects from the dust removal port 203 out of the dust collection chamber 201 to the base station 300, thereby achieving the dust collection function.

[0057] Optionally, the handheld vacuum cleaner 200 is provided with an elastic member, and the shielding member 210 is rotatably provided at the dust removal port 203. The elastic member is used to limit the shielding member 210 to the covering position, and the elastic member is in an elastically compressed state when the shielding member 210 is in the open position.

[0058] In some embodiments, the shielding member 210 is configured to be attracted by the fan 209 and move to the closed position. In some embodiments, the shielding member 210 is configured to be moved to the closed position by the combined action of the fan 209 and the elastic recovery of the elastic member. In some embodiments, the elastic member can be omitted, and the shielding member 210 itself can be made of an elastic material, for example, the shielding member 210 can be made of rubber. In some embodiments, the shielding member 210 can also be configured to be driven by a motor to move between the closed position and the open position.

[0065] When the handheld vacuum cleaner 200 is in a separated state from the device main body 100, the second electrical connection part 220 is not electrically connected to the first electrical connection part 110, and when the handheld vacuum cleaner 200 is in a connected state with the device main body 100, the second electrical connection part 220 is electrically connected to the first electrical connection part 110; in these two states, the voltage on the second electrical connection part 220, that is, the above-mentioned transmission voltage will change. In this embodiment, the voltage change of the second electrical connection part 220 can be detected by the insertion detection circuit 125a, and this change can be fed back to the main control circuit 123a. The main control circuit 123a can determine the electrical connection state between the second electrical connection part 220 and the first electrical connection part 110 based on the detection result of the insertion detection circuit 125a, and when the two are electrically connected, control the power supply circuit 121a to supply power to the second electrical connection part 220, so as to supply power to the first electrical connection part 110, thereby supplying power to the power supply circuit 22a of the device main body 100, so that the device main body 100 is powered.

[0071] Among them, R446=R448+R450.

[0072] When the voltage of the detection terminal BASE_DET changes from the first preset voltage value to the second preset voltage value, the main control circuit 123a controls the power supply circuit 121a, i.e., the VBASE1 terminal electrically connects the power supply circuit 22a of the device body 100 to the VBASE2 terminal to supply power to the device body 100.

[0106] Furthermore, as shown in FIG11 , the second electrical connection portion 220 and the first electrical connection portion 110 are electrically connected by plugging or elastically abutting.

[0107] In other embodiments, a power supply component 221 is detachably provided on the device body 100, or, in some embodiments, batteries may be provided on the device body 100 and the handheld vacuum cleaner 200 respectively. When the handheld vacuum cleaner 200 is assembled on the device body 100, the two batteries are connected in series.

[0112] Optionally, as shown in Figures 4 and 6, the limiting column 106 is provided with a hook portion 107, and the groove wall of the limiting groove 204 is provided with a snap groove 205. The hook portion 107 is used to be embedded in the snap groove 205 when the limiting column 106 is inserted into the limiting groove 204, so that the handheld vacuum device 200 is snap-connected to the device body 100.

[0113] Furthermore, the handle 241 forms part of the wall of the limiting groove 204, and the buckle groove 205 is provided on the handle 241. Alternatively, as shown in FIG11 , the device body 240 forms part of the wall of the limiting groove 204, and the buckle groove 205 is provided on the device body 240.

[0114] Optionally, the hook portion 107 protrudes from the side of the limiting column 106. The insertion direction of the hook portion 107 into the buckle slot 205 intersects with the extension direction of the limiting column 106. Further, the limiting column 106 extends along the height direction D4 of the self-propelled cleaning device 1.

[0115] Furthermore, the device body 100 includes an unlocking mechanism 109, which is movably mounted on the limiting post 106 and is exposed to the outside world. The unlocking mechanism 109 is configured to be pressed to disengage the hook portion 107 from the locking groove 205, thereby releasing the locking connection between the handheld vacuum cleaner 200 and the device body 100. Furthermore, the unlocking mechanism 109 is mounted on the upward-facing top surface of the limiting post 106 to facilitate user depressing.

[0116] Alternatively, as shown in Figures 8 and 11, the first electrical connection portion 110 is disposed on the periphery of the limiting column 106, and the second electrical connection portion 220 is disposed adjacent to the snap groove 205. The second electrical connection portion 220 and the first electrical connection portion 110 are plugged into or elastically abutted against each other along the height direction D4 of the self-propelled cleaning device 1. In this way, the stability of the second electrical connection portion 220 and the first electrical connection portion 110 can be improved.

[0119] Specifically, the recessed groove 105 is connected to the outside through the extension opening 1051. Part of the handheld vacuum device 200 can be located in the extension opening 1051. For example, the bottom wall of the recessed groove 105 is provided with the extension opening 1051.

[0120] Furthermore, a portion of the handheld vacuum cleaner 200 can extend outward through the extension opening 1051. Specifically, the travel mechanism supports the device body 100, thereby forming a space at the bottom 122 of the device body 100, thereby separating the device body 100 from a work surface (e.g., the ground). The recessed groove 105 can communicate with the space through the extension opening 1051, and a portion of the handheld vacuum cleaner 200 can extend into the space through the extension opening 1051. This arrangement helps further reduce the height of the self-propelled cleaning device 1. In some embodiments, the extension opening 1051 can also be omitted.

This arrangement makes the center of gravity layout of the device body 100 more compact and reasonable, while also facilitating installation and removal of the handheld vacuum cleaner 200 from the device body 100. The forward direction of the self-propelled cleaning device 1 refers to the direction in which the self-propelled cleaning device 1 moves while cleaning the scene to be cleaned.

[0123] Optionally, the dust outlet 103 is disposed at the tail portion 129. This arrangement helps reduce the distance between the dust outlet 103 and the dust collection chamber 201, shortening the path length of waste objects during dust collection and reducing the risk of blockage. Accordingly, in this embodiment, the dust collection outlet 301 is disposed on the base station body 310. In some embodiments, the dust outlet 103 may also be disposed at the bottom portion 122. Accordingly, in this embodiment, the dust collection outlet 301 is disposed on the base 30.

[0124] Optionally, as shown in FIG9 , the outer shape of the handheld vacuum cleaner 200 matches the contour of the peripheral side 123 of the device body 100. For example, the peripheral contour of the tail portion 129 is arc-shaped, and accordingly, the outer contour of the handheld vacuum cleaner 200 near the peripheral contour of the tail portion 129 is a matching arc-shaped contour to correspond to and match the peripheral contour of the tail portion 129.

[0125] 9 , on a reference plane perpendicular to the height direction D4 of the self-propelled cleaning device 1, the projection of the handheld vacuum device 200 falls within the projection of the device body 100. Specifically, the projection of the handheld vacuum device 200 on the working surface falls within the projection of the device body 100 on the working surface.

[0126] Optionally, as shown in Figure 6, the self-propelled cleaning device 1 also includes an accessory 400a for the handheld vacuum cleaner 200. The accessory 400a is designed to be mounted on the air inlet 202.

The head portion 128 defines a receiving slot 108, into which the accessory 400a is removably received. This arrangement makes the layout of the device body 100 more compact and reasonable.

[0127] 6 , the self-propelled cleaning device 1 further includes an accessory 400a for the handheld dust collecting device 200. At least one accessory 400a is detachably mounted on the device body 100.

For example, the accessory 400a can include a vacuum tube 400 and a brush head 402. The brush head 402 can be used for cleaning sofas, crevices, and other application scenarios.

[0129] Specifically, the suction tube 400 is configured to be detachably mounted to the air inlet 202 when the handheld vacuum device 200 is detached from the device body 100. The suction tube 400 can be used to improve the compatibility of the handheld vacuum device 200 with cleaning scenarios.

[0131] In some embodiments, as shown in Figures 8 and 14 , a suction tube 400 is detachably mounted on the device body 100. The suction tube 400 can function as a suction nozzle. Specifically, the diameter of the end of the suction tube 400 away from the air inlet 202 can be smaller than the diameter of the air inlet 202, thereby facilitating cleaning of narrow gaps and enhancing suction.

[0132] By detachably setting the dust suction tube 400 on the device body 100, the original space of the device body 100 is fully utilized, and the space occupied by the entire cleaning system is reduced. The device body 100 can store the dust suction tube 400, which is also convenient for taking out the dust suction tube 400 when needed.

The first docking port 4001 is used to communicate with the air inlet 202. The second docking port 4002 is used to allow waste objects to enter the extension channel 4005.

[0138] The floor brush assembly 403 is arranged at the second docking interface 4002. The floor brush assembly 403 can be used to clean the work surface. The dust and garbage swept out by the floor brush assembly 403 can be sucked into the extension channel 4005 through the second docking interface 4002 under the suction force of the handheld vacuum cleaner 200, and then pass through the extension channel 4005 and the first docking interface 4001 in turn, and then be sucked into the dust collecting chamber 201 of the handheld vacuum cleaner 200 through the air inlet 202.

[0139] Optionally, the floor brush assembly 403 includes a floor brush body, a driving motor and a brush body. The driving motor is arranged on the floor brush body.

A wire may be provided in the extension tube 404 and connected between the second electrical connection contact 4003 and the third electrical connection contact. In this way, when the extension tube 404 is assembled and connected to the handheld vacuum cleaner 200 and the floor brush assembly 403 respectively, the power supply assembly 221 can supply power to the floor brush assembly 403. By extending the extension tube 404, the suction range of the handheld vacuum cleaner 200 can be extended to a farther distance. Through the floor brush assembly 403, dust and garbage on the work surface can be swept out, thereby enriching the application scenarios of the handheld vacuum cleaner 200 and improving the cleaning effect.

[0146] Optionally, the extension tube 404 and the floor brush assembly 403 are detachably connected via a third and fourth snap-fitting portions. This facilitates a stable connection between the extension tube 404 and the floor brush assembly 403 and helps maintain the electrical connection stability between the third and fourth electrical connection contacts. The configuration of the third and fourth snap-fitting portions can also be similar to that described above for the first and second snap-fitting portions 2022 and 4004.

[0147] Optionally, as shown in FIG. 17 , the cleaning system 10 includes a storage bracket 401 , and the storage bracket 401 is configured to fix an idle accessory 400 a .

[0148] Optionally, the storage bracket 401 is provided with at least two fixing positions, one of which can be used to fix the idle extension tube 404, and the other fixing position can be used to fix the idle brush head 402. The extension tube 404 or the brush head 402 can be removed from the storage bracket 401 when work is needed.

[0149] Optionally, the device body 100 includes a laser radar 127, which is used to draw a three-dimensional map and perform positioning functions. The laser radar 127 is installed in the area between the accommodating groove 108 and the recessed groove 105.

[0150] Optionally, as shown in FIG6 , the handheld vacuum cleaner 200 includes a housing 242 that is detachably connected to the device body 240 to form a dust collection chamber 201. An air inlet 202 is provided on the device body 240, a dust removal port 203 is provided on the housing 242, a fan 209 is provided within the device body 240, and a handle 241 is connected to the device body 240.

[0151] In some embodiments, as shown in FIG. 4 , when the receiving portion 242 is detached from the device body 240 , the separation space 232 is exposed to the outside world, so that garbage objects in the separation space 232 can be dumped to the outside world.

[0152] Optionally, the power supply assembly 221 is disposed adjacent to the accommodating portion 242 .

[0153] Optionally, as shown in Figures 9 and 11 to 13, the handheld vacuum cleaner 200 includes a control button group 2411, and the handle 241 and the air inlet 202 are respectively disposed on opposite sides of the device body 240. The handle 241 has a first end and a second end. The power supply assembly 221 is adjacent to the first end of the handle 241, and the second end of the handle 241 is connected to the device body 240. The control button group 2411 is disposed on the handle 241 and is adjacent to the second end of the handle 241.

[0154] Specifically, as shown in Figures 9 and 11 to 13, the handheld vacuum cleaner 200 has a first direction D1, a second direction D2, and a third direction D3 that are mutually perpendicular. The handle 241 and the air inlet 202 are respectively disposed on either side of the handheld vacuum cleaner 200 along the first direction D1, thereby facilitating the user's grip on the handheld vacuum cleaner 200 for cleaning. The fan 209 and the power supply assembly 221 are respectively disposed on either side of the handheld vacuum cleaner 200 along the second direction D2. Both the fan 209 and the power supply assembly 221 are relatively heavy, thereby facilitating a balanced weight distribution throughout the handheld vacuum cleaner 200, facilitating the user's balance when gripping the handheld vacuum cleaner 200, and making the handheld vacuum cleaner 200 more ergonomically designed.

[0155] Optionally, the handheld vacuum cleaner 200 is provided with an exhaust vent 207 that communicates with the outside world. The fan 209 is connected to the exhaust vent 207. Specifically, the air inlet 2091 is connected to the outside world through the exhaust vent 207. The exhaust vent 207 faces the outside world along a third direction D3. This ensures that when a user holds the handheld vacuum cleaner 200 for cleaning, the exhaust vent 207 is not directly facing the user or the area being cleaned, thereby reducing the impact of the airflow from the exhaust vent 207 on the cleaning process.

[0156] Optionally, when the handheld vacuum cleaner 200 is assembled and connected to the device body 100 , the exhaust port 207 is arranged to face upward, and the device body 100 is arranged to avoid the exhaust port 207 .

[0157] When the handheld vacuum cleaner 200 is assembled and connected to the device body 100, the device body 100 can avoid the exhaust port 207 so that air can be discharged smoothly from the exhaust port 207. For example, when the handheld vacuum cleaner 200 is assembled and connected to the device body 100, the exhaust port 207 can face upward.

[0158] Furthermore, the fan 209 has an air outlet 2092 connected to the air inlet 2091 , and air flows into the fan 209 from the air inlet 2091 and flows out of the fan 209 from the air outlet 2092 . Furthermore, the air outlet 2092 is connected to the exhaust port 207 .

[0159] Optionally, the power supply assembly 221 is located at a corner of the handheld vacuum cleaner 200 near the handle 241. When the user holds the handheld vacuum cleaner 200 for cleaning, the power supply assembly 221 can be located at the bottom and the fan 209 can be located at the top and front. Under the weight of the fan 209 and the power supply assembly 221, the air inlet 202 can be oriented to a position slightly forward and downward, thereby facilitating the user's cleaning activities.

[0160] Optionally, when the handheld vacuum device 200 is assembled to the device body 100 , the third direction D3 is parallel to the height direction D4 of the self-propelled cleaning device 1 .

[0161] Optionally, as shown in FIG9 , a control button group 2411 is provided at the second end of the handle 241 in the second direction D2. The control button group 2411 is used to control the power on / off and gear switching functions of the handheld vacuum cleaner 200. This arrangement facilitates the user to hold the handle 241 with one hand while pressing the control button group 2411 with their thumb, while reducing the risk of accidental touch or pressing of the control button group 2411. When the user removes the handheld vacuum cleaner 200 from the device body 100, they can press the unlocking mechanism 109 with one hand while holding the handle 241, and then press the control button group 2411 to start the handheld vacuum cleaner 200.

[0162] Optionally, as shown in FIG9 , an indicator light 243 is provided on the handheld vacuum cleaner 200 .

[0163] Optionally, as shown in Figures 4, 6, and 12, the handheld vacuum cleaner 200 includes a fan 209 and a filter assembly 230. The filter assembly 230 is disposed on a side of the fan 209 near the dust collection chamber 201. The filter assembly 230 is used to intercept waste objects that enter the dust collection chamber 201 through the air inlet 202 and allow the waste objects to enter the dust collection chamber 201. By providing the filter assembly 230, the airflow and the waste objects can be separated from each other, allowing the dust collection chamber 201 to collect the waste objects.

[0164] For example, the filter assembly 230 includes a centrifugal separation mechanism 231. Since air and garbage objects have different densities, the centrifugal separation mechanism 231 can separate the airflow and garbage objects through the principle of centrifugal separation.

[0165] The centrifugal separation mechanism 231 is connected to the device body 240 and is located in the dust collecting chamber 201. This is beneficial for evenly distributing the overall weight of the handheld vacuum device 200.

[0166] Optionally, the centrifugal separation mechanism 231 is located between the fan 209 and the accommodating portion 242, and the air inlet 202 is located between the fan 209 and the accommodating portion 242. In this way, the air inlet 202 is centered, which facilitates the handheld vacuum cleaner 200 to be used by hand.

[0167] Optionally, as shown in Figures 10 to 12, the centrifugal separation mechanism 231 has a separation space 232 therein, which is in communication with the air inlet 2091 and the dust collection chamber 201, respectively. The airflow generated by the fan 209 flows sequentially through the dust suction port 101, the air inlet 202, the dust collection chamber 201, the separation space 232, and the air inlet 2091. The dust collection chamber 201 is used to receive large particles of waste that are intercepted by the centrifugal separation mechanism 231 outside the separation space 232. The centrifugal separation mechanism 231 is used to centrifugally separate the airflow and waste in the separation space 232, thereby retaining small particles of waste in the separation space 232.

[0168] Optionally, as shown in Figures 10 to 12 , filter assembly 230 includes an interception net 233 disposed at the entrance of separation space 232. Interception net 233 can prevent large waste objects from entering separation space 232, thereby improving the efficiency of separating airflow from waste objects. Specifically, interception net 233 is a metal mesh.

[0169] In some embodiments, as shown in Figures 10 to 12, the centrifugal separation mechanism 231 further includes an air outlet 234 communicating with the separation space 232, and the separation space 232 is communicated with the exhaust port 207 via the air outlet 234. The purified air flow in the separation space 232 can flow toward the air inlet 2091 through the air outlet 234 and finally be discharged to the outside through the exhaust port 207.

[0170] 10 to 12 , a filter element 250 may be provided between the fan 209 and the filter assembly 230 . Furthermore, the filter element 250 is provided between the centrifugal separation mechanism 231 and the fan 209 .

[0171] Optionally, the handheld vacuum cleaner 200 is provided with a communication port 2013, through which the dust collection chamber 201 communicates with the separation space 232. During dust collection by the base station 300, garbage objects in the separation space 232 enter the dust collection chamber 201 through the communication port 2013, then leave the dust collection chamber 201 through the dust removal port 203 and enter the base station 300 through the dust collection port 301.

[0172] Optionally, as shown in Figures 10 to 12, the handheld dust collection device 200 includes a partition 2014, which is movably disposed at the communication port 2013 to open or close the communication port 2013. The base station 300 includes a dust collection fan 320 in communication with the dust collection port 301. The partition 2014 is configured to be attracted by the dust collection fan 320 and move from a position covering the communication port 2013 to a position opening the communication port 2013. In some embodiments, the partition 2014 is configured to be attracted by the fan 209 and move from a position opening the communication port 2013 to a position covering the communication port 2013.

[0173] When the self-propelled cleaning device 1 is performing cleaning work or the handheld vacuum cleaner 200 is removed from the device body 100 and held for cleaning work, the partition 2014 can be in a position covering the communication port 2013. When the self-propelled cleaning device 1 needs to collect dust, the partition 2014 can be in a position opening the communication port 2013 due to the suction force of the dust collection fan 320.

[0174] Optionally, the handheld vacuum cleaner 200 is provided with an elastic reset member, and the partition 2014 is rotatably provided on the communication opening 2013. The elastic reset member is used to limit the partition 2014 to a position covering the communication opening 2013, and the elastic reset member is in an elastically compressed state when the partition 2014 is in a position opening the communication opening 2013.

[0175] In other embodiments, as shown in FIG4 , different from the embodiment shown in FIG12 , in the embodiment shown in FIG4 , the partition 2014 is omitted, and the connecting port 2013 extends to abut against the inner wall of the accommodating portion 242 . In this embodiment, the garbage in the separation space 232 cannot be sucked away by the base station, and the user can pour out the garbage in the separation space 232 by removing the accommodating portion 242 .

[0176] Optionally, as shown in Figure 10, the device body 100 includes a body 130, a roller brush 1011 and comb teeth 1012. The roller brush 1011 is rotatably connected to the body 130 and is arranged at the suction port 101. The comb teeth 1012 are connected to the body 130 and are used to clean the hair wrapped around the roller brush 1011.

[0177] Optionally, as shown in Figures 10 and 12 , the handheld vacuum cleaner 200 includes a blocking member 2023 for blocking the air inlet 202. The blocking member 2023 is movably disposed on the air inlet 202 so as to be switchable between a blocking position and a connecting position relative to the air inlet 202. The blocking member 2023 is configured to cover the air inlet 202 in the blocking position and is further configured to be attracted by the fan 209 or the dust collection fan 320 to move from the blocking position to the connecting position to open the air inlet 202. Furthermore, the blocking member 2023 blocks the air inlet 202 within the handheld vacuum cleaner 200.

[0178] Optionally, the handheld dust suction device 200 includes an elastic pressing member, which is used to keep the blocking member 2023 in the blocking position through elastic action.

[0179] The dust collection process of the base station 300 is described in further detail below.

[0180] The cleaning system 10 described in the embodiment of the cleaning system of the present application includes a self-propelled cleaning device 1 and a base station 300 for docking with the self-propelled cleaning device 1. The self-propelled cleaning device 1 has a dust collecting chamber 201. The self-propelled cleaning device 1 includes a fan 209, which is connected to the dust collecting chamber 201. The fan 209 is used to form an airflow into the dust collecting chamber 201, and the dust collecting chamber 201 is used to accommodate garbage objects carried by the airflow. The base station 300 includes a dust collecting fan 320, and the dust collecting fan 320 is used to suck the garbage objects in the dust collecting chamber 201 into the base station 300. The cleaning system 10 has a dust collection mode. In the dust collection mode: the self-propelled cleaning device 1 and the base station 300 are docked. The dust collecting fan 320 and the fan 209 have an alternating start-up phase. In the alternating start-up phase, the dust collecting fan 320 and the fan 209 are alternately started.

[0181] In some embodiments, the self-propelled cleaning device 1 and the base station 300 cooperate with each other to perform a dust collection method. The dust collection method includes: S100: controlling the self-propelled cleaning device to dock with the base station; S200: controlling the dust collection fan and the fan to operate in sequence; S300: controlling the dust collection fan to operate again.

[0182] When the dust collection fan 320 is operating, it draws waste objects within the dust collection chamber 201 along the suction path into the base station 300. If there is a large amount of waste objects within the dust collection chamber 201, the suction path can easily become clogged with waste objects. For example, waste objects within the dust collection chamber 201 can be drawn into the dust bag of the base station 300 through the dust collection channel 1031. If there is a large amount of waste objects within the dust collection chamber 201, this can easily cause waste objects to clog the dust collection channel 1031 or the entrance to the dust collection channel 1031. The dust collection fan 320 can be controlled to activate at least twice. When the dust collection fan 320 is activated and operating, its operating power and operating time can be controlled to initially draw some of the waste objects within the dust collection chamber 201 into the base station 300, minimizing the risk of waste object blockage. When the dust collection fan 320 is subsequently activated and operating, the remaining waste objects within the dust collection chamber 201 can be drawn into the base station 300.

[0183] During the alternating start-up phase, when the dust collecting fan 320 is controlled to stop working, the fan 209 can be controlled to start. The airflow path formed by the operation of the fan 209 is different from the airflow path formed by the operation of the dust collecting fan 320. Therefore, the operation of the fan 209 can reduce the risk of blockage by garbage objects and improve the dust collection effect.

[0184] In addition, the dust collecting fan 320 and the fan 209 are started alternately, which can reduce the noise generated.

[0185] In some embodiments, in the dust collection mode: in the alternating start-up phase, the fan 209 and the dust collection fan 320 work alternately to reduce the noise generated and to avoid the partial airflow generated by the dust collection fan 320 and the fan 209 from offsetting each other.

[0186] In other embodiments, during the alternating startup phase, the dust collection fan 320 and the fan 209 partially overlap in their operating time. That is, during the alternating startup phase, the dust collection fan 320 and the fan 209 may operate at different times or simultaneously. The simultaneous operation of the dust collection fan 320 and the fan 209 can create a more complex airflow path, further reducing dust collection blind spots and enhancing the suction force on the roller brush 1011, thereby enhancing the cleaning effect of the roller brush 1011.

[0187] In some embodiments, step S200 may be performed once during the dust collection process. In other embodiments, step S200 may be repeated during the dust collection process, and step S200 may be performed at least twice. For example, step S200 may be performed two or three times, and step S300 is performed after step S200 is performed two or three times.

[0188] In some embodiments, during the dust collection process, the dust collection fan 320 may be started continuously for at least two times, after which the dust collection fan 320 stops working and the fan 209 starts.

[0189] In some embodiments, during the dust collection process, the fan 209 may be started continuously for at least two times, after which the fan 209 stops working and the dust collection fan 320 starts.

[0190] Optionally, in the dust collection mode: the dust collection fan 320 is started for the first time before the fan 209 is started for the first time. Further, the dust collection fan 320 works for the first time before the fan 209 works for the first time, that is, the dust collection fan 320 stops working for the first time before the fan 209 is started for the first time.

[0191] With such an arrangement, the garbage objects in the dust collecting chamber 201 can be sucked into the base station 300 as early as possible, which is beneficial to shortening the dust collection time.

[0192] In other embodiments, in the dust collection mode, the fan 209 is started first.

[0193] Optionally, in the dust collection mode: the dust collection fan 320 is last started after the last start of the fan 209. Further, the dust collection fan 320 last works after the fan 209 last works, that is, the dust collection fan 320 last starts after the fan 209 last stops working.

[0194] For example, during the dust collection process, dust collection fan 320 may operate twice and fan 209 may operate once, with the operation of fan 209 occurring between the two operations of dust collection fan 320. For another example, during the dust collection process, dust collection fan 320 may operate three times and fan 209 may operate two times. For example, dust collection fan 320 and fan 209 may operate alternately according to the sequence in Table 1. For another example, dust collection fan 320 and fan 209 may operate alternately according to Tables 2 and 3.

[0195] Table 1 Example of the working sequence of the dust collection fan, blower and roller brush motor in dust collection mode

[0196] Optionally, there is a power increase process in the operation of the dust collecting fan 320. During the power increase process, the operating power of the dust collecting fan 320 in the previous operation process is less than the operating power in the next operation process.

[0197] Furthermore, in the dust collection mode: the dust collection fan 320 is started at least twice, and the working power of the dust collection fan 320 when it is started for the first time is less than the working power when it is started for the second time.

[0198] Such a setting can ensure that during the dust collection process, the working power of the dust collecting fan 320 is relatively small before the power raising process, so that the amount of garbage objects sucked by the dust collecting fan 320 will not be too large, and it is not easy to cause blockage of garbage objects. After the power raising process, the working power of the dust collecting fan 320 is relatively large, which is conducive to fully sucking garbage objects into the base station 300 and improving the dust collection effect.

[0199] In some embodiments, as shown in Table 1, the power boosting process occurs during the first and second operations of the dust collecting fan 320 , and the ratio of the operating power to the rated power of the dust collecting fan 320 increases from 65% to 100%.

[0200] In some embodiments, the power boost process may occur during three or four consecutive operations of the dust collecting fan 320. For example, the ratio of the operating power of the dust collecting fan 320 to the rated power may be increased from 40% during the first operation to 65% during the second operation, and then to 100% during the third operation. The number of operations of the dust collecting fan 320 included in the power boost process may be set based on the capacity of the dust collecting chamber 201 and the cross-section of the suction path. The larger the capacity of the dust collecting chamber 201 and the smaller the cross-section of the suction path, the more times the dust collecting fan 320 will operate during the power boost process, and the lower the operating power of the dust collecting fan 320 in the early stages of the operation.

[0201] Certainly, in other embodiments, the operating power of the dust collecting fan 320 when it is first started may also be equal to the operating power when it is started for the second time. In this embodiment, the operating power of the dust collecting fan 320 when it is started each time may remain consistent.

[0202] In some embodiments, the ratio of the operating power to the rated power of the dust collecting fan 320 may be 30%, 40%, 50% or 70%.

[0203] Optionally, during the power increase process, the ratio of the working power of the dust collecting fan 320 in the previous working process to the working power in the next working process ranges from 50% to 80%.

[0204] For example, the ratio of the working power of the dust collecting fan 320 in the previous working process to the working power in the next working process is in the range of 55%, 65% or 75%.

[0205] Optionally, the operating power of the dust collecting fan 320 after the power raising process is the same as the last operating power during the power raising process.

[0206] Furthermore, in the dust collection mode: the dust collecting fan 320 is started at least three times, and the working power of the dust collecting fan 320 each time after the second start-up is the same as the working power of the second start-up.

[0207] The dust collection fan 320 can be activated at its maximum operating power or another set power level for the second time. For example, if the dust collection fan 320 is activated at 100% of its rated power for the second time, the dust collection fan 320 will be activated at 100% of its rated power after the second activation. This helps to fully draw waste objects into the base station 300, improving dust collection efficiency. For example, after reaching its maximum operating power, the dust collection fan 320 may continue to operate for one, two, or three times.

[0208] Optionally, during the dust collection process, the operating power of the fan 209 can be 80% of the rated power, which helps to increase the service life of the fan 209. The operating power of the fan 209 can also be 80% of the rated power when the self-propelled cleaning device 1 is cleaning the work surface. It is worth mentioning that the rated power of the fan 209 can be less than or equal to the rated power of the dust collection fan 320.

[0209] Optionally, during the power increase process, the operating duration of the dust collecting fan 320 in the next operating process is longer than the operating duration of the previous operating process. For example, as shown in Table 1, during the power increase process, the operating duration of the dust collecting fan 320 in the next operating process is 8 seconds, while the operating duration of the previous operating process is 5 seconds. In other words, during the power increase process, as the operating power of the dust collecting fan 320 increases, the operating duration of each dust collecting fan 320 also increases.

[0210] In other embodiments, if the dust collecting fan 320 operates more than twice during the power raising process, the operating time of the dust collecting fan 320 may be gradually increased. For example, the operating time of the dust collecting fan 320 may be increased from 5 seconds for the first operation to 8 seconds for the second operation, and then to 12 seconds for the third operation. In the later stage of the power raising process, the operating time of the dust collecting fan 320 may be set according to the capacity of the dust collecting chamber 201 and the cross-section of the suction path. The larger the capacity of the dust collecting chamber 201 and the smaller the cross-section of the suction path, the longer the operating time of the dust collecting fan 320 may be in the later stage of the power raising process.

[0211] In some embodiments, the dust collecting fan 320 may work for 3 seconds, 10 seconds, or 15 seconds each time.

[0212] Optionally, the last operating duration of the dust collecting fan 320 during the power boost process is longer than the single operating duration of the dust collecting fan 320 after the power boost process. For example, as shown in Table 1, the last operating duration of the dust collecting fan 320 during the power boost process is 8 seconds, and the single operating duration of the dust collecting fan 320 after the power boost process is 5 seconds. For another example, the last operating duration of the dust collecting fan 320 during the power boost process is 12 seconds, and the single operating duration of the dust collecting fan 320 after the power boost process is 6 seconds.

[0213] When the dust collecting fan 320 works for the last time during the power raising process, its working power and working time reach the maximum, and most of the garbage objects can be sucked into the base station 300. Therefore, when the dust collecting fan 320 works after the power raising process, the single working time is short, which is beneficial to saving suction time and improving time efficiency.

[0214] Optionally, after the dust collecting fan stops working, controlling the fan operation includes:

[0215] S201: Controlling the dust collecting fan to operate after stopping the fan for a preset interval.

[0216] After the fan stops working, controlling the dust collection fan to work again includes:

[0217] S301: Controlling the dust collecting fan to operate after the fan is stopped for a preset interval.

[0218] For example, as shown in Table 1, the preset interval is 1 second. Fan 209 is controlled to start 1 second after dust collection fan 320 is stopped, and dust collection fan 320 is controlled to start 1 second after fan 209 is stopped. In other embodiments, the preset interval can also be set to 0.5 seconds, 2 seconds, or 3 seconds. In addition, the two preset intervals can be the same or different.

[0219] After the dust collecting fan 320 or the fan 209 stops, there will be a lag in stopping the generated airflow. By setting a preset interval time, the situation where part of the airflow generated by the dust collecting fan 320 and the fan 209 offsets each other can be reduced.

[0220] Optionally, in the dust collection mode, the fan 209 has at least a first operating power and a second operating power, wherein the first operating power is less than the second operating power. For example, as shown in Table 2, the first operating power may be 12% of the rated power, and the second operating power may be 80% of the rated power.

[0221] In this way, the fan 209 can change the dust collecting power to achieve different functional effects.

[0222] Furthermore, in the dust collection mode: during at least one continuous operation of the fan 209 , the operating power of the fan 209 is increased from the first operating power to the second operating power.

[0223] Specifically, the fan 209 operates at a first operating power to suck garbage objects into the dust collecting chamber 201 , and operates at a second operating power to move and lift garbage objects in the dust collecting chamber 201 so that they can be fully sucked into the base station 300 .

[0224] Table 2 Another example of the working sequence of the fan in dust collection mode

[0225] Table 3 Another example of the working sequence of the dust collection fan in dust collection mode

[0226] Table 4 Another example of the working sequence of the roller brush motor in dust collection mode

[0227] Optionally, the self-propelled cleaning device 1 further includes a roller brush motor for driving the roller brush 1011 to rotate. In dust collection mode, the roller brush motor drives the roller brush 1011 to rotate alternately between forward and reverse directions. The forward direction is the direction of rotation of the roller brush 1011 when the self-propelled cleaning device 1 is cleaning the work surface.

[0228] As shown in Table 1 and Table 4, when the voltage of the roller brush motor is positive, the roller brush 1011 is controlled to rotate in the forward direction. When the voltage of the roller brush motor is negative, the roller brush 1011 is controlled to rotate in the reverse direction.

[0229] Optionally, in the dust collection mode, after the roller brush motor is first started, the roller brush 1011 is driven to rotate forward. At the beginning of the dust collection process, in order to prevent the roller brush 1011 from spitting out large particles of garbage from the suction port 101, the roller brush motor is driven to rotate forward first after the first start, and then switches to reverse rotation. Of course, in other embodiments, the roller brush motor can also first drive the roller brush 1011 to rotate reversely.

[0230] Optionally, in the dust collection mode: the stopping time of the roller brush 1011 after the last start is earlier than the stopping time of the dust collection fan 320 after the last start.

[0231] The dust collecting fan 320 can suck the garbage objects on the roller brush 1011 into the dust collecting chamber 201 and further suck them into the base station 300. Such an arrangement is conducive to improving the cleaning effect of the dust collecting fan 320 on the roller brush 1011.

[0232] Optionally, in the dust collection mode, the roller brush 1011 switches from forward rotation to reverse rotation at least twice. That is, in the dust collection mode, the roller brush 1011 rotates forward and reverse at least twice. This arrangement is conducive to improving the cleaning effect of the roller brush 1011.

[0233] Specifically, in this embodiment, the dust discharge port 103 is located at the rear portion 129 of the device body 100. Therefore, in dust collection mode, the rear portion of the self-propelled cleaning device 1 docks with the base station 300, that is, the rear portion 129 of the device body 100 docks with the base station 300. As shown in FIG5 , the self-propelled cleaning device 1 also includes a charging electrode 500. The charging electrode 500 is located at the bottom 122 of the device body 100, near the head portion 128. Therefore, in charging mode, the head portion of the self-propelled cleaning device 1 docks with the base station 300, that is, the head portion 128 of the device body 100 docks with the base station 300. That is, when the self-propelled cleaning device 1 needs to perform dust collection, it first moves toward the base station 300 with its rear portion 129 facing the base station 300. After completing the dust collection operation, the self-propelled cleaning device 1 must first leave the base station 300, rotate 180 degrees, and then move its head portion 128 toward the base station 300 to allow the base station 300 to charge the self-propelled cleaning device 1. In this embodiment, setting the charging electrode 500 at the bottom 122 of the device body 100 and close to the head 128 can reduce the weight of the tail 129 of the device body 100, reasonably distribute the center of gravity of the self-propelled cleaning device 1, and avoid the phenomenon of the self-propelled cleaning device 1 tilting during walking.

[0234] In other embodiments, the charging electrode 500 can also be set at the tail 129 of the device body 100. In this way, in the charging mode and the dust collection mode, the docking position of the self-propelled cleaning device 1 and the base station 300 is the same. When the dust collection mode is changed to the charging mode, the self-propelled cleaning device 1 does not need to change its position to improve the overall efficiency.
