Description

Technical Field

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

[0002] Cleaning robots, equipped with functions such as washing, sweeping, and mopping, can perform cleaning tasks like floor cleaning for users, bringing them great convenience and thus gaining widespread application. Cleaning robots are typically equipped with a base station. Currently, traditional base stations on the market usually integrate dust bags inside to collect the dirt collected by the cleaning robot. Due to the limited internal space of the base station, the volume of the dust bag is often small, meaning users often need to replace the dust bag frequently, which is time-consuming and laborious. Summary of the Invention

[0003] This application provides a cleaning system and a dust collection device, which helps to reduce the frequency of maintenance and the cost of use for users.

[0004] This application provides a cleaning system, including: a cleaning device; a base station; and a dust collection device externally connected to the base station; wherein the dust collection device includes: a device body; a negative pressure component disposed on the device body; a dust collection bin detachably connected to the device body and also connected to the negative pressure component, the dust collection bin being used to store dirt; and a dust collection pipe connected to the dust collection bin and also connected to the base station, the negative pressure component being used to create a negative pressure environment inside the dust collection bin, so that the dust collection pipe collects dirt from the cleaning device into the dust collection bin through the base station.

[0005] In one embodiment of this application, the dust collection bin has a locking tongue and a first driving mechanism. The device body has a locking groove. The first driving mechanism is connected to the locking tongue. When the dust collection bin is connected to the device body, the locking tongue is embedded in the locking groove. The first driving mechanism is used to drive the locking tongue to disengage from the locking groove so as to allow the dust collection bin and the device body to separate from each other.

[0006] In one embodiment of this application, the first driving mechanism includes: a handle rotatably disposed in the dust collection bin; a connecting rod, one end of which is rotatably connected to the handle; and a movable member rotatably connected to the other end of the connecting rod. The bin locking tongue is disposed on the movable member, and the connecting rod is driven to move the movable member by rotating the handle. The movable member is used to drive the bin locking tongue to disengage from the locking groove.

[0007] In one embodiment of this application, the bucket locking tongue includes a first bucket locking tongue and a second bucket locking tongue, which are respectively disposed near opposite sides of the dust collection bucket. The moving part includes a first moving part and a second moving part, with the first bucket locking tongue disposed on the first moving part and the second bucket locking tongue disposed on the second moving part.

[0011] In one embodiment of this application, the second driving mechanism includes: a movable member movably disposed on the cover body, the cover latch being located on the movable member, and the movable member being used to drive the cover latch out of the fixed groove.

[0012] In one embodiment of this application, the cover latch includes a first cover latch and a second cover latch; the movable member includes a first movable member and a second movable member, the first cover latch being located on the first movable member and the second cover latch being located on the second movable member, wherein the moving direction of the first movable member is different from the moving direction of the second movable member; the second driving mechanism further includes: a linkage post, disposed on one of the first movable member and the second movable member; and a linkage groove, disposed on the other of the first movable member and the second movable member, the linkage post being movably embedded in the linkage groove; wherein, in the moving direction of the first cover latch disengaging from the fixed groove, the linkage groove extends toward the second cover latch, so that when the first movable member drives the first cover latch to disengage from the fixed groove, the second movable member drives the second cover latch to disengage synchronously from the corresponding fixed groove.

[0013] In one embodiment of this application, the cover has a guide channel, and a movable component is movably embedded in the guide channel. The guide channel is used to guide the movable component to move so as to drive the cover latch out of the fixed channel.

[0014] In one embodiment of this application, the guide channel includes a first channel segment and a second channel segment that are connected. The width of the first channel segment is smaller than the width of the second channel segment, such that the channel wall of the second channel segment adjacent to the first channel segment forms a first limiting surface facing away from the first channel segment. The movable member includes a first movable part and a second movable part that are connected. The first movable part is movably embedded in the first channel segment, and the second movable part is movably embedded in the second channel segment. The cover latch is located at the end of the first movable part away from the second movable part. The outer side wall of the second movable part adjacent to the first movable part has a second limiting surface facing the side where the first movable part is located. The first limiting surface and the second limiting surface cooperate to restrict the movable member from disengaging from the guide channel.

[0015] In one embodiment of this application, the second driving mechanism further includes: a guide member, including a guide portion and a limiting portion, the limiting portion being connected to the cover through the guide portion; and a guide groove, disposed on the movable member, the guide portion being movably embedded in the guide groove, the guide groove extending along the moving direction of the movable member, and the limiting portion being located on the side of the guide groove away from the cover, the limiting portion being used to restrict the movable member from separating from the cover.

[0016] In one embodiment of this application, the second driving mechanism further includes a second elastic member, which is connected to the movable member and the cover respectively. The second elastic member is used to drive the cover locking tongue to re-embed into the fixing groove through the movable member.

[0017] In one embodiment of this application, the movable part is provided with a latching groove. The user latches the movable part through the latching groove, thereby driving the movable part to disengage the cover latch from the fixed groove.

[0018] Accordingly, this application also provides a dust collection device for use as a base station external to a cleaning device. The dust collection device includes: a device body; a negative pressure component disposed on the device body; a dust collection bin detachably connected to the device body and also connected to the negative pressure component, the dust collection bin being used to store dirt; and a dust collection pipe connected to the dust collection bin and also connected to the base station. The negative pressure component is used to create a negative pressure environment inside the dust collection bin, so that the dust collection pipe can collect dirt from the cleaning device into the dust collection bin through the base station.

[0019] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a cleaning system and a dust collection device. The dust collection device includes a negative pressure component, a dust collection bin, and a dust collection pipe. The dust collection bin is used to store dirt and is also connected to the negative pressure component. The dust collection pipe is connected to the dust collection bin and also to the base station. The negative pressure component creates a negative pressure environment inside the dust collection bin, allowing the dust collection pipe to collect dirt from the cleaning device back to the dust collection bin via the base station. In this application, the dust collection device is external to the base station, meaning it is located outside the base station rather than integrated inside. This allows for a larger dust collection bin volume to collect dirt, without being limited by the internal space of the base station. Users no longer need to maintain the dust collection bin frequently (e.g., cleaning the dirt from the bin), thus reducing maintenance frequency and user burden. Furthermore, users can choose whether to equip the base station with a dust collection device based on actual needs, meeting more diverse user requirements.

[0020] Furthermore, the dust collection bin of this application is detachably connected to the main body of the dust collection device. When the dust collection bin needs to be cleaned, the user can remove it from the main body of the device to clean it, and then reinstall the dust collection bin back into the main body after cleaning. Traditional base stations typically use dust bags to collect waste, and dust bags, as consumables, undoubtedly increase the user's operating costs. The dust collection bin of this application, however, is reusable, replacing dust bags and reducing the user's operating costs. Attached Figure Description

[0041] This application provides a cleaning system and a dust collection device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0042] Please see Figures 1a-1c , Figures 1a-1c This is a schematic diagram of an embodiment of the base station and dust collection device of this application.

[0043] In one embodiment, the cleaning system includes a cleaning device and a base station 10. The cleaning device can be a cleaning robot or other cleaning equipment, capable of moving autonomously across the surface to be cleaned and cleaning the areas it passes through. Of course, in other embodiments of this application, the cleaning device can also be a washing machine, floor scrubber, or other cleaning equipment, where the user holds the cleaning device and pushes it across the surface to be cleaned, thus cleaning the areas it passes through. This application uses a cleaning robot as an example for illustration only and is not intended to limit the scope of the application. The cleaning device has cleaning components for performing cleaning work, which can be roller brushes, cloths, brushes, etc. This application uses a roller brush as an example. The cleaning device also has a dust box 30, used to store dirt collected by the cleaning device during the cleaning process. The cleaning device is used in conjunction with the base station 10, which is used for charging the cleaning device and other tasks to assist the cleaning device in its cleaning work.

[0044] The cleaning system also includes a dust collection device 20. As its name suggests, the dust collection device 20 has a dust collection function. The dust collection device 20 is externally connected to the base station 10, and it collects dirt from the cleaning device through the base station 10. In this embodiment, the dust collection device 20 is externally connected to the base station 10, meaning it is located outside the base station 10 rather than integrated inside. This allows for a larger volume of dust collection device 20 to collect dirt, without being limited by the internal space of the base station 10. Users no longer need to maintain the dust collection device 20 frequently (e.g., cleaning the dirt from it), thus reducing maintenance frequency and user burden. The external connection of the dust collection device 20 to the base station 10 should be understood as a detachable connection. Users can connect the dust collection device 20 to the base station 10, and it can then be used to collect dirt from the cleaning device, achieving immediate use. Furthermore, users can choose whether the base station 10 is equipped with the dust collection device 20 according to their actual needs, meeting more diverse user requirements. Of course, the dust collection device 20 and the base station 10 can also be fixedly connected, which is not limited here.

[0045] Please refer to the following: Figure 2 , Figure 2 This is an exploded structural diagram of an embodiment of the dust collection device of this application. The dust collection device 20 of this application embodiment will be described below.

[0046] In one embodiment, the dust collection device 20 includes a device body 21. As the name suggests, the device body 21 serves as the basic carrier of the dust collection device 20, supporting and protecting the other components of the dust collection device 20. The dust collection device 20 also includes a negative pressure component 22, which is disposed within the device body 21. The dust collection device 20 further includes a dust collection component 23, which is disposed within the device body 21 and connected to the negative pressure component 22. The dust collection component 23 is also connected to the base station 10. The negative pressure component 22 creates a negative pressure environment within the dust collection component 23, allowing the dust collection component 23 to collect dirt from the cleaning device via the base station 10.

[0047] Base station 10 includes base station body 11. As its name suggests, base station body 11 is the basic carrier of base station 10, providing support and protection for the remaining components of base station 10. For example... Figure 1a and Figure 1b As shown, the base station 10 also includes a dust collection component 12, which is disposed on the base station body 11 and is used to connect with the dust collection assembly 23. The dust collection component 12 has a dust collection channel inside, and a dust collection port 121 communicating with the dust collection channel is opened on the top of the dust collection component 12. The dust collection port 121 is used to dock with the dust box 30 of the cleaning device when the cleaning device returns to the base station 10. The dirt in the dust box 30 is collected into the dust collection assembly 23 in sequence through the dust collection port 121 and the dust collection channel.

[0048] Since the dust box 30 is usually located near the bottom of the cleaning device, in this embodiment, the dust collection component 12 is located near the bottom of the base station body 11, so that when the cleaning device returns to the base station 10, the dust collection port 121 can easily dock with the dust box 30. An external sheet metal part can also be provided on the main body 21 of the dust collection device 20, and the dust collection device 20 is connected to the base station 10 through the external sheet metal part, so that the dust collection device 20 is externally connected to the base station 10.

[0049] The dust collection assembly 23 includes a dust collection bin 231 and a dust collection pipe 232. The dust collection bin 231 is connected to the negative pressure assembly 22 and is used to store the collected dirt. The dust collection pipe 232 is connected to the dust collection bin 231 and is also used to connect to the base station 10. The negative pressure assembly 22 is used to create a negative pressure environment inside the dust collection bin 231, so that the dust collection pipe 232 can collect dirt from the cleaning device into the dust collection bin 231 through the base station 10.

[0050] The dust collection bin 231 is detachably connected to the main body 21 of the dust collection device 20. When the dust collection bin 231 needs to be cleaned, the user removes it from the main body 21 to clean it. After cleaning, the dust collection bin 231 is reinstalled back into the main body 21. Traditional base stations 10 typically use dust bags to collect waste, which, as consumables, undoubtedly increase the user's operating costs. In this embodiment, the dust collection bin 231 is reusable, replacing the dust bag and reducing the user's operating costs.

[0051] One end of the dust collection pipe 232 is fixed to the main body 21 of the dust collection device 20 via a sheath and clamps to connect to the dust collection bin 231. The other end of the dust collection pipe 232 is used to connect to the dust collection component 12 of the base station 10. The dust collection pipe 232 protrudes from the main body 21, facilitating unblocking and cleaning when the dust collection pipe 232 is clogged. Several elastic clamps are provided on the main body 21, through which the dust collection pipe 232 is fixed to the main body 21. The dust collection pipe 232 can be a corrugated flexible hose, meaning its length is adjustable. When the user needs to use the dust collection device 20, the user extends the dust collection pipe 232 and connects it to the base station 10. After use, the user can easily store the dust collection pipe 232 and re-fix it to the main body 21 of the dust collection device 20. Furthermore, the power cord and signal line of the dust collection device 20 are electrically connected to the base station body 11 via an aviation connector, so that the base station 10 can supply power to the dust collection device 20 and control the dust collection device 20 to operate. The aviation connector enables waterproof and dustproof functions between the power cord and signal line of the dust collection device 20 and the base station body 11.

[0052] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram of an embodiment of the fan and housing of this application. Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the fan and its enclosure.

[0053] In one embodiment, the negative pressure assembly 22 includes a fan 221, which creates a negative pressure environment in the dust collection assembly 23, allowing the dust collection assembly 23 to collect dirt from the cleaning device via the base station 10. The negative pressure assembly 22 also includes a cover 222. The cover 222 has a receiving cavity 2221 and an air intake channel 2222 and an air exhaust channel 2223 communicating with the receiving cavity 2221. The fan 221 is housed in the receiving cavity 2221. The fan 221 is connected to the dust collection assembly 23 via the air intake channel 2222 and connected to the outside of the cover 222 via the air exhaust channel 2223. The fan 221 draws gas from the dust collection assembly 23 through the air intake channel 2222 and discharges it to the outside of the cover 222 via the air exhaust channel 2223, thereby creating a negative pressure environment in the dust collection assembly 23.

[0054] Optionally, the cover 222 includes an upper cover 2225 and a lower cover 2226. The upper cover 2225 and the lower cover 2226 are joined to form a receiving cavity 2221. In this embodiment, the fan 221 can be a centrifugal fan 221 or the like, and the exhaust method of the fan 221 is centrifugal exhaust. The suction channel 2222 is located at the top of the fan 221, and the exhaust channel 2223 surrounds the outer periphery of the fan 221. The fan 221 draws gas from the dust collection assembly 23 through the suction channel 2222 at its top and exhausts the gas centrifugally through the circumferential exhaust channel 2223.

[0055] In one embodiment, the negative pressure assembly 22 further includes a suction seal 223, which surrounds a suction channel 2222 and also serves to seal the area between the fan 221 and the cover 222 at the location of the suction channel 2222, ensuring the airtightness of the suction channel 2222 and improving dust collection efficiency and effect. Specifically, the cover 222 also has a suction port 2224, which communicates with the accommodating cavity 2221. Specifically, the suction port 2224 is located at the top of the cover 222, and the suction seal 223 is also located at the top of the cover 222. The suction seal 223 includes a first sealing part 2231, a second sealing part 2232, and a connecting part 2233. The connecting part 2233 passes through the suction port 2224. The first sealing part 2231 is connected to the end of the connecting part 2233 near the fan 221, and the first sealing part 2231 is sandwiched between the cover 222 and the fan 221 to form a seal. The second sealing part 2232 is connected to the end of the connecting part 2233 away from the fan 221. The second sealing part 2232 extends to the outside of the cover 222. Please refer to the following: Figure 5 , Figure 5A portion of the dust collection device 20 is cut open to reveal its internal structure. The negative pressure assembly 22 also includes a suction pipe 224. The suction pipe 224 is connected to the dust collection assembly 23, specifically to the dust collection bin 231. The suction pipe 224 also abuts against the second sealing part 2232 to form a seal, ensuring the airtightness of the suction pipe 224 and its connection with the second sealing part 2232, which helps improve dust collection efficiency and effect. The fan 221 draws gas from the dust collection assembly 23 through the suction pipe 224.

[0056] Furthermore, please refer to the following: Figure 6 , Figure 6 A portion of the structure is cut open to reveal its internal components. Considering the significant wind noise generated by the exhaust gas from the exhaust duct 2223, the negative pressure assembly 22 in this embodiment also includes a silencer 225. The silencer 225 is connected to the enclosure 222, and the gas exhausted from the exhaust duct 2223 passes through the silencer 225 before being discharged to the outside of the negative pressure assembly 22. In this way, the silencer 225 effectively reduces the wind noise of the gas exhausted from the exhaust duct 2223.

[0057] The silencer 225 is located at the bottom of the enclosure 222. The exhaust duct 2223 includes a first sub-duct 2223a and a second sub-duct 2223b connected together. The first sub-duct 2223a surrounds the outer periphery of the accommodating cavity 2221, and the second sub-duct 2223b extends toward the silencer 225 to connect to it. The gas drawn in by the fan 221 is discharged to the silencer 225 through the first sub-duct 2223a and the second sub-duct 2223b in sequence. The gas centrifugally discharged by the fan 221 enters the first sub-duct 2223a and flows circumferentially along the fan 221 to the second sub-duct 2223b. The gas reaching the second sub-duct 2223b flows along the second sub-duct 2223b to the silencer 225, and is finally discharged to the outside of the enclosure 222 after being reduced in noise by the silencer 225. The main body 21 of the device includes a base 211, a main body 212, and a support 213. The main body 212 and the base 211 are mated to form a mounting cavity, the support 213 is installed in the mounting cavity, and the cover 222 is disposed on the support 213. Please refer to the following: Figure 7 The main body 212 also has an exhaust port 2122. The mounting cavity is connected to the outside through the exhaust port 2122. The gas discharged through the exhaust channel 2223 is discharged to the outside of the mounting cavity through the exhaust port 2122. The gas discharged from the silencer 225 enters the mounting cavity and is then discharged to the outside through the exhaust port 2122. There can be multiple exhaust ports 2122, and each exhaust port 2122 is arranged at intervals on the main body 212. Figure 7 An example is shown where each exhaust vent 2122 is distributed at intervals along the height direction of the main body 212.

[0058] The upper cover 2225 and the lower cover 2226 of the enclosure are joined to form a first sub-channel 2223a, and a second sub-channel 2223b is located in the lower cover 2226. The negative pressure assembly 22 also includes a first exhaust seal 2261, which is sandwiched between the fan 221 and the lower cover 2226, so that a seal is formed between the fan 221 and the lower cover 2226 at the location of the first exhaust seal 2261, ensuring the airtightness of the first sub-channel 2223a and preventing the gas discharged by the fan 221 from wandering around in the enclosure 222. The negative pressure assembly 22 also includes a second exhaust seal 2262, which is sandwiched between the upper cover 2225 and the lower cover 2226 of the enclosure, forming a seal between the upper cover 2225 and the lower cover 2226 at the location of the second exhaust seal 2262. This ensures the airtightness of the first sub-channel 2223a and prevents the gas discharged from the fan 221 from escaping within the enclosure 222. Furthermore, the first exhaust seal 2261 is located on the side of the first sub-channel 2223a closer to the receiving cavity 2221, while the second exhaust seal 2262 is located on the side of the first sub-channel 2223a away from the receiving cavity 2221. The first exhaust seal 2261 and the second exhaust seal 2262 cooperate to seal the first sub-channel 2223a.

[0059] In one embodiment, considering that the fan 221 will generate a large amount of heat during long-term operation and needs to be dissipated in a timely manner to ensure its reliable operation, the cover 222 in this embodiment is also provided with a first heat dissipation air inlet 2227 and a heat dissipation air outlet 2228. The first heat dissipation air inlet 2227 is connected to the accommodating cavity 2221, and the heat dissipation air outlet 2228 is also connected to the accommodating cavity 2221. Under the suction action of the fan 221, the gas outside the cover 222 enters the accommodating cavity 2221 through the first heat dissipation air inlet 2227 to dissipate heat from the fan 221, and then is discharged to the outside of the cover 222 through the heat dissipation air outlet 2228.

[0060] Since the operating temperature of the fan 221 is much higher than the ambient temperature, the lower temperature of the gas in the ambient environment can be used to dissipate heat from the fan 221. In this embodiment, the fan 221 not only has the function of creating a negative pressure environment in the dust collection assembly 23, but also can draw relatively cool gas from outside the cover 222 into the accommodating cavity 2221 through the first heat dissipation air inlet 2227 to dissipate heat from the fan 221. The gas entering from the first heat dissipation air inlet 2227 exchanges heat with the fan 221, and then is discharged to the outside of the cover 222 through the heat dissipation air outlet 2228.

[0061] Specifically, the first heat dissipation air inlet 2227 is located at the bottom of the cover 222. The heat dissipation air outlet 2228 is located on the side wall of the cover 222, and the heat dissipation air outlet 2228 is closer to the first heat dissipation air inlet 2227 than the first sub-channel 2223a. The outer side wall of the fan 221 is spaced apart from the inner side wall of the cover 222 to form a first heat dissipation flow channel 226. The gas entering from the first heat dissipation air inlet 2227 passes through the first heat dissipation flow channel 226 and is discharged through the heat dissipation air outlet 2228. There can be multiple first heat dissipation air inlets 2227, and each first heat dissipation air inlet 2227 is distributed at intervals at the bottom of the cover 222.

[0062] Furthermore, the dust collection device 20 also includes an air inlet seal 26, which is sandwiched between the bottom of the fan 221 and the cover 222 to form a seal. The air inlet seal 26 is used to separate the first heat dissipation air inlet 2227 from the first heat dissipation flow channel 226, so as to ensure that under the suction action of the fan 221, the gas outside the cover 222 flows from the first heat dissipation air inlet 2227 to the fan 221 to dissipate heat from the fan 221, and prevents the gas from bypassing the fan 221 and being discharged directly from the heat dissipation air outlet 2228, which is beneficial to ensuring the heat dissipation effect of the fan 221.

[0063] In one embodiment, the main body 212 of the device body 21 has a second heat dissipation air inlet 2121 communicating with the outside of the mounting cavity. The device body 21 also includes a heat dissipation sealing cover 215, which is connected to the bracket 213 of the device body 21 and is located on the bottom side of the cover 222. The heat dissipation sealing cover 215 and the bracket 213 cooperate to form a heat dissipation air inlet channel 216 and separate the heat dissipation air inlet channel 216 from the rest of the mounting cavity. The heat dissipation air inlet channel 216 communicates with the first heat dissipation air inlet 2227 and the second heat dissipation air inlet 2121 respectively. The heat dissipation sealing cover 215 and the portion of the bracket 213 located on the bottom side of the cover 222 form the heat dissipation air inlet channel 216, and this portion of the heat dissipation sealing cover 215 is away from the cover 222 relative to the bracket 213. The heat dissipation air inlet channel 216 is relatively sealed, so the heat dissipation sealing cover 215 can separate the heat dissipation air inlet channel 216 from the rest of the mounting cavity. Since the gas discharged from the silencer 225 has a high temperature and will be discharged into the installation cavity, the heat dissipation sealing cover 215 in this embodiment can prevent the gas from entering the heat dissipation air intake channel 216, thus ensuring the heat dissipation effect of the fan 221.

[0064] Optionally, there can be multiple second heat dissipation air inlets 2121, and each second heat dissipation air inlet 2121 is distributed sequentially at intervals along the height direction of the body 212. Furthermore, the second heat dissipation air inlets 2121 and the aforementioned exhaust vents 2122 are located on the same side of the body 212, such as... Figure 7 As shown.

[0065] Please refer to the following: Figure 8 and Figure 9 , Figure 8 This is an exploded structural diagram of an embodiment of the negative pressure assembly and support of this application. Figure 9 This is a partial cross-sectional view of another embodiment of the negative pressure component of this application assembled on the bracket.

[0066] In one embodiment, the device body 21 has an assembly cavity 217 for assembling the cover 222. Specifically, the assembly cavity 217 is located on the support 213 of the device body 21. The inner wall of the assembly cavity 217 is provided with a first baffle 2181 and a second baffle 2182, which are spaced apart from each other along the circumference of the cover 222. When the cover 222 is assembled into the assembly cavity 217, the cover 222, the device body 21, the first baffle 2181, and the second baffle 2182 cooperate to form a second heat dissipation channel 228. The second heat dissipation channel 228 and the heat dissipation outlet 2228 are located on the same side of the first baffle 2181 and the second baffle 2182. The first heat dissipation channel 226 is connected to the second heat dissipation channel 228 through the heat dissipation outlet 2228. The high-temperature gas, after being cooled by the fan 221, is discharged sequentially through the first heat dissipation channel 226, the heat dissipation outlet 2228, and the second heat dissipation channel 228. The gas flow direction is as follows: Figure 9 As indicated by the middle arrow M.

[0067] In this embodiment, the first baffle 2181 and the second baffle 2182 form a second heat dissipation channel 228, which forms a separate chamber. The second heat dissipation channel 228 is used to guide the high-temperature gas after the fan 221 has been cooled to discharge, so as to prevent the gas from flowing to other positions of the dust collection device 20.

[0068] Specifically, there are at least two first baffles 2181, and each first baffle 2181 is distributed sequentially at intervals along the circumference of the cover 222. Figure 8 The example illustrates a scenario where two first baffles 2181 are arranged close to each other. A first rib 2229a protrudes from the outer wall of the cover 222, and is embedded in the gap between adjacent first baffles 2181. Because the first baffles 2181 and the first rib 2229a are close to each other, they form a relatively sealed structure to ensure the airtightness of the second heat dissipation channel 228. Of course, in other embodiments of this application, sealing elements such as sealant or sealing rings can be provided between the first baffles 2181 and the first rib 2229a to further improve the airtightness of the second heat dissipation channel 228.

[0069] Similarly, there are at least two second baffles 2182, and each second baffle 2182 is distributed sequentially at intervals along the circumference of the cover 222. Figure 8 The example demonstrates a case where there are two second baffles 2182, which are arranged close to each other. The outer wall of the cover 222 also has a protruding second rib 2229b, which is embedded in the gap between adjacent second baffles 2182. Because the second baffles 2182 and the second rib 2229b are close to each other, they can form a relatively sealed structure to ensure the airtightness of the second heat dissipation channel 228. Of course, in other embodiments of this application, sealing elements such as sealant or sealing rings can be provided between the second baffles 2182 and the second rib 2229b to further improve the airtightness of the second heat dissipation channel 228.

[0070] In one embodiment, the dust collection device 20 further includes a first heat dissipation seal 241 and a second heat dissipation seal 242. The first heat dissipation seal 241 is located near the top of the second heat dissipation channel 228 and is sandwiched between the cover 222 and the device body 21 to seal the top of the second heat dissipation channel 228. The second heat dissipation seal 242 is located near the bottom of the second heat dissipation channel 228 and is sandwiched between the cover 222 and the device body 21 to seal the bottom of the second heat dissipation channel 228. In this way, this embodiment uses the first heat dissipation seal 241 and the second heat dissipation seal 242 to seal the second heat dissipation channel 228, thereby further improving the airtightness of the second heat dissipation channel 228.

[0071] Optionally, the first heat dissipation seal 241 can be a semi-annular structure to match the structure of the second heat dissipation channel 228 enclosed by the first baffle 2181 and the second baffle 2182. The second heat dissipation seal 242 can be a complete annular structure to maximize the airtightness of the second heat dissipation channel 228.

[0072] Please refer to the following: Figures 10 to 13 , Figure 10 This is a schematic diagram of another embodiment of the dust collection device of this application. Figure 11 This is a schematic diagram of the structure of an embodiment of the dust collection bin of this application. Figure 12 yes Figure 11 The diagram shows a bottom view of the dust collection bin. Figure 13 yes Figure 12 The diagram shows another state of the dust collection bin. The following describes the detachable connection between the dust collection bin 231 and the main body 21 of the dust collection device 20 in this embodiment of the application.

[0073] In one embodiment, the dust collection bin 231 includes a bin body 2311, which has a dirt collection chamber 2314 with one end open, used to store dirt. The dust collection bin 231 also includes a cover 2312 connected to the bin body 2311, used to close the opening. When the dust collection bin 231 needs cleaning, the user drives the cover 2312 to open the opening, allowing the dirt stored in the dirt collection chamber 2314 to be discharged through the opening, thus achieving the purpose of cleaning the dust collection bin 231. Figure 13 As shown. After the dust collection bin 231 is cleaned, the user drives the cover 2312 to close the opening, and the dust collection bin 231 can be reused to collect dirt, such as... Figure 12 As shown.

[0074] Optionally, the cover 2312 is rotatably connected to the main body 2311 of the dust collection bin. When the dust collection bin 231 needs to be cleaned, the user drives the cover 2312 to rotate away from the opening to open it. After the dust collection bin 231 is cleaned, the user drives the cover 2312 to rotate towards the opening to close it. Of course, in other embodiments of this application, the cover 2312 can also be detachably connected to the main body 2311 of the bin as a whole. When the cover 2312 is completely removed from the main body 2311 of the bin, the cover 2312 opens the opening, and when the cover 2312 is completely installed on the main body 2311 of the bin, the cover 2312 closes the opening. This is not limited to this embodiment.

[0075] It should be noted that the aforementioned opening is located at the bottom of the sludge collection chamber 2314, and the cover 2312 is connected to the bottom of the main body 2311. Thus, after the cover 2312 opens the opening, the dirt in the sludge collection chamber 2314 can be discharged through the opening under its own weight, making it convenient for the user to clean the dust collection bin 231. Of course, in other embodiments of this application, the opening may also be located at the top or side of the sludge collection chamber 2314, with the cover 2312 corresponding to the opening; this is not limited here.

[0076] Please refer to the following: Figure 14 and Figure 15 , Figure 14 yes Figure 10 A schematic cross-sectional view of the dust collection device shown. Figure 15 yes Figure 10 The diagram shows the rear structure of the dust collection device, in which... Figure 15 The outer casing on the back of the dust collection device 20 is omitted to show the internal structure.

[0077] In one embodiment, the dust collection bin 231 has a locking tongue 233 and a first driving mechanism 234, specifically, the locking tongue 233 and the first driving mechanism 234 are disposed on the bin body 2311 of the dust collection bin 231. The first driving mechanism 234 is kinetically connected to the locking tongue 233. The device body 21 has a locking groove 235. When the dust collection bin 231 is connected to the device body 21, the locking tongue 233 is embedded in the locking groove 235, and the first driving mechanism 234 is used to drive the locking tongue 233 to disengage from the locking groove 235, so as to allow the dust collection bin 231 to separate from the device body 21. When it is necessary to clean the dust collection bin 231, the user drives the locking tongue 233 to disengage from the locking groove 235 through the first driving mechanism 234, so that the user can remove the dust collection bin 231 from the device body 21. After the dust collection bin 231 is cleaned, the user can reinstall the dust collection bin 231 back into the device body 21.

[0078] Specifically, the first drive mechanism 234 includes a handle 2341, a connecting rod 2342, and a movable component 2343. The handle 2341 is rotatably mounted on the dust collection bin 231. One end of the connecting rod 2342 is rotatably connected to the handle 2341, and the movable component 2343 is rotatably connected to the other end of the connecting rod 2342. A bin locking tongue 233 is mounted on the movable component 2343. Rotation of the handle 2341 drives the connecting rod 2342 to move the movable component 2343, which in turn drives the bin locking tongue 233 to disengage from the locking groove 235. When the dust collection bin 231 needs to be cleaned, the user follows... Figure 14 Pull the handle 2341 in the direction indicated by the dashed arrow N to make the handle 2341 rotate relative to the main body 2311 of the dust collection bin. As the handle 2341 rotates, it drives the connecting rod 2342 to rotate and move along the direction in which the bin locking tongue 233 disengages from the locking groove 235. This causes the connecting rod 2342 to drive the moving part 2343 to move along the direction in which the bin locking tongue 233 disengages from the locking groove 235. In turn, the moving part 2343 drives the bin locking tongue 233 to disengage from the locking groove 235. After the bin locking tongue 233 disengages from the locking groove 235, the user can remove the dust collection bin 231 from the main body 21 of the device.

[0079] Furthermore, the bucket locking tongue 233 includes a first bucket locking tongue 2331 and a second bucket locking tongue 2332, which are respectively disposed near opposite sides of the dust collection bucket 231. For example, the first bucket locking tongue 2331 and the second bucket locking tongue 2332 may be disposed near the top side and the bottom side of the dust collection bucket 231, respectively. Of course, in other embodiments of this application, the first bucket locking tongue 2331 and the second bucket locking tongue 2332 may also be disposed near the left side and the right side of the dust collection bucket 231, respectively, which is not limited here. The device body 21 is provided with locking grooves 235 corresponding to the first bucket locking tongue 2331 and the second bucket locking tongue 2332. When the dust collection bucket 231 is connected to the device body 21, the first bucket locking tongue 2331 and the second bucket locking tongue 2332 are respectively embedded in the corresponding locking grooves 235. When the dust collection bin 231 needs to be cleaned, the first bin locking tongue 2331 and the second bin locking tongue 2332 respectively disengage from the corresponding locking groove 235 to allow the dust collection bin 231 to separate from the device body 21.

[0080] The movable component 2343 includes a first movable component 23431 and a second movable component 23432. A first barrel locking tongue 2331 is disposed on the first movable component 23431, and a second barrel locking tongue 2332 is disposed on the second movable component 23432. The first drive mechanism 234 also includes a linkage gear 2344. The first movable component 23431 is rotatably connected to the connecting rod 2342, and the first movable component 23431 is also connected to the second movable component 23432 via the linkage gear 2344. Specifically, both the first movable component 23431 and the second movable component 23432 mesh with the linkage gear 2344. The first movable component 23431 and the second movable component 23432 can move towards each other as the handle 2341 rotates, synchronously driving the first barrel locking tongue 2331 and the second barrel locking tongue 2332 to disengage from their respective locking grooves 235. When the user pulls the handle 2341, the handle 2341 drives the connecting rod 2342 to rotate. The connecting rod 2342 drives the first moving part 23431 and the second moving part 23432 to move towards each other, and simultaneously drives the first locking tongue 2331 and the second locking tongue 2332 to disengage from the corresponding locking groove 235.

[0081] In one embodiment, the first drive mechanism 234 further includes a first elastic element 2345, which is connected to both the dust collection bin 231 and the moving part 2343. The first elastic element 2345 is used to drive the bin locking tongue 233 to re-engage the locking groove 235 via the moving part 2343. Specifically, the first elastic element 2345 can be an elastic element such as a spring. One end of the first elastic element 2345 is fixed to the bin body 2311, and the other end is connected to the first moving part 23431. When the user pulls the handle 2341, causing the first moving part 23431 to move, the first moving part 23431 compresses the first elastic element 2345. When the user releases the handle 2341, the first elastic element 2345, in response to its own elastic restoring force, drives the first moving part 23431 to reset. At the same time, the first moving part 23431 drives the second moving part 23432 to move away from the first moving part 23431 via the linkage gear 2344.

[0082] Please refer to the following: Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the structure of one embodiment of the cover of this application. Figure 17 yes Figure 16 A schematic diagram of the cross-sectional structure of the cover shown.

[0083] In one embodiment, the dust collection bin 231 further includes a lid latch 236 and a second drive mechanism 238. The lid latch 236 is disposed on the lid body 2312, and the bin body 2311 has a fixing groove 237. When the lid body 2312 closes the opening, the lid latch 236 is embedded in the fixing groove 237. The second drive mechanism 238 is disposed on the lid body 2312 and is drively connected to the lid latch 236. The second drive mechanism 238 is used to drive the lid latch 236 to disengage from the fixing groove 237, so as to allow the lid body 2312 to open the opening. When the dust collection bin 231 needs to be cleaned, the user removes the dust collection bin 231 from the device body 21, and the user drives the cover locking tongue 236 to disengage from the fixing groove 237 through the second drive mechanism 238, so that the cover body 2312 rotates away from the opening to open the opening; after the dust collection bin 231 is cleaned, the user drives the cover body 2312 to rotate towards the opening to close the opening, and at the same time, the cover locking tongue 236 on the cover body 2312 re-embeds into the fixing groove 237, and then the user puts the dust collection bin 231 back into the device body 21.

[0084] Specifically, the second drive mechanism 238 includes a movable member 2381. The movable member 2381 is movably disposed on the cover 2312, and the cover latch 236 is located on the movable member 2381. The movable member 2381 is used to disengage the cover latch 236 from the fixing groove 237. The movable member 2381 has a latching groove 23816, which the user uses to latch the movable member 2381, thereby driving the movable member 2381 to disengage the cover latch 236 from the fixing groove 237.

[0085] Furthermore, the lid latch 236 includes a first lid latch 2361 and a second lid latch 2362. The movable member 2381 includes a first movable member 23811 and a second movable member 23812. The first lid latch 2361 is located in the first movable member 23811, and the second lid latch 2362 is located in the second movable member 23812. The bucket body 2311 is provided with fixing grooves 237 corresponding to the first lid latch 2361 and the second lid latch 2362, respectively. When the lid body 2312 closes the opening, the first lid latch 2361 and the second lid latch 2362 are respectively embedded in the corresponding fixing grooves 237. When it is necessary to clean the dust collection bucket 231, the first lid latch 2361 and the second lid latch 2362 are respectively disengaged from the corresponding fixing grooves 237 to allow the lid body 2312 to open the opening. The fixing groove 237 corresponding to the first cover latch 2361 and the fixing groove 237 corresponding to the second cover latch 2362 are located on different sides of the barrel body 2311. The moving direction of the first movable member 23811 is different from that of the second movable member 23812, so that the first movable member 23811 and the second movable member 23812 can be embedded in their respective fixing grooves 237.

[0086] The second drive mechanism 238 also includes a linkage post 2382 and a linkage groove 2383. The linkage post 2382 is disposed on one of the first movable member 23811 and the second movable member 23812, and the linkage groove 2383 is disposed on the other of the first movable member 23811 and the second movable member 23812. The linkage post 2382 is movably embedded in the linkage groove 2383. In the direction of movement of the first cover latch 2361 disengaging from the corresponding fixing groove 237, the linkage groove 2383 extends toward the second cover latch 2362, so that when the first movable member 23811 drives the first cover latch 2361 to disengage from the fixing groove 237, the second movable member 23812 drives the second cover latch 2362 to simultaneously disengage from the corresponding fixing groove 237.

[0087] The latching groove 23816 is provided in the first movable member 23811. When the dust collection bin 231 needs to be cleaned, the user latches the first movable member 23811 through the latching groove 23816, causing the first movable member 23811 to drive the first cover latch 2361 to disengage from the corresponding fixed groove 237; as the first movable member 23811 moves, the linkage column 2382 moves along the linkage groove 2383, driving the second movable member 23812 to move synchronously so that the second cover latch 2362 disengages synchronously from the corresponding fixed groove 237. Figure 16 An exemplary illustration shows a configuration where the linkage groove 2383 is located on the first movable member 23811, and the linkage post 2382 is located on the second movable member 23812. There are two second movable members 23812, each located on opposite sides of the first movable member 23811. Movement of the first movable member 23811 synchronously drives the two second movable members 23812 to move towards each other, causing the first cover latch 2361 and the two second cover latches 2362 to simultaneously disengage from their corresponding fixing grooves 237, achieving a three-sided unlocking function. The movement directions of the first movable member 23811 and the two second movable members 23812 are as follows: Figure 16 As indicated by the dashed arrow.

[0088] In one embodiment, the second driving mechanism 238 further includes a second elastic element 2386. The second elastic element 2386 is connected to the movable element 2381 and the cover 2312 respectively, and is used to drive the cover locking tongue 236 to re-embed into the fixing groove 237 through the movable element 2381. Specifically, the second elastic element 2386 can be an elastic element such as a spring, with one end fixed to the cover 2312 and the other end connected to the movable element 2381. When the user presses the movable element 2381, the movable element 2381 compresses the second elastic element 2386; when the user releases the movable element 2381, the second elastic element 2386 responds to its own elastic restoring force to drive the movable element 2381 to reset. In this embodiment, the dust collection bin 231 is provided with a second elastic element 2386 corresponding to the first movable element 23811 and the second movable element 23812 respectively, so as to drive the first movable element 23811 and the second movable element 23812 to reset.

[0089] In one embodiment, the cover 2312 has a guide channel 2313, and the movable member 2381 is movably embedded in the guide channel 2313. The guide channel 2313 is used to guide the movable member 2381 to move so as to drive the cover latch 236 out of the fixed channel. Specifically, the cover 2312 is provided with guide channels 2313 corresponding to the first movable member 23811 and the second movable member 23812, respectively. The guide channels 2313 corresponding to the first movable member 23811 and the guide channels 2313 corresponding to the second movable member 23812 extend in different directions to guide the first movable member 23811 and the second movable member 23812 to move in different directions, thereby driving the first cover latch 2361 and the second cover latch 2362 out of the corresponding fixed groove 237.

[0090] For the guide channel 2313 corresponding to the first movable member 23811, the guide channel 2313 includes a first channel segment 2313a and a second channel segment 2313b that are connected. The width of the first channel segment 2313a is smaller than the width of the second channel segment 2313b, such that the channel wall of the second channel segment 2313b adjacent to the first channel segment 2313a forms a first limiting surface 2313c facing away from the first channel segment 2313a. The movable member 2381 (i.e., the first movable member 23811) includes a first movable part 23813 and a second movable part 23814 that are connected. The first movable part 23813 is movably embedded in the first channel segment 2313a, and the second movable part 23814 is movably embedded in the second channel segment 2313b. The cover latch 236 (i.e., the first cover latch 2361) is located at the end of the first movable part 23813 away from the second movable part 23814. The outer wall of the second movable part 23814 adjacent to the first movable part 23813 has a second limiting surface 23815 facing the side where the first movable part 23813 is located. The first limiting surface 2313c cooperates with the second limiting surface 23815 to restrict the movable member 2381 from disengaging from the guide channel 2313.

[0091] In one embodiment, the second drive mechanism 238 further includes a guide member 2384, which includes a guide portion 23841 and a limiting portion 23842. The limiting portion 23842 is connected to the cover 2312 via the guide portion 23841. The movable member 2381 is provided with a guide groove 2385, in which the guide portion 23841 is movably embedded. The guide groove 2385 extends along the moving direction of the movable member 2381, and the limiting portion 23842 is located on the side of the guide groove 2385 opposite to the cover 2312, serving to restrict the movable member 2381 from separating from the cover 2312. During the movement of the movable member 2381, the guide portion 23841 of the guide member 2384 moves along the guide groove 2385, thus guiding the movement of the movable member 2381.

[0092] The guide 2384 can be a washer, screw, etc. The screw of the guide 2384 is locked to the cover 2312, and this screw is the guide part 23841. The washer of the guide 2384 is located on the side of the guide groove 2385 away from the cover 2312. The washer limits the movable part 2381 in the direction perpendicular to the cover 2312 (i.e., the up and down direction), preventing the movable part 2381 from tilting up during movement, that is, restricting the movable part 2381 from separating from the cover 2312. In this embodiment, the dust collection bin 231 is provided with the guide 2384 and the guide groove 2385 corresponding to the first movable part 23811 and the second movable part 23812, respectively.

[0093] The technical solutions provided in the embodiments of this application will be described below in conjunction with specific application scenarios.

[0094] Application Scenario 1:

[0095] The cleaning system includes a cleaning device (a cleaning robot) and a base station 10. The system also includes a dust collection device 20. The dust collection device 20 is externally connected to the base station 10 and collects dirt from the cleaning device through the base station 10. In this application scenario, the dust collection device 20 is external to the base station 10, meaning it is located outside the base station 10 rather than integrated inside. This allows for a larger volume of dust collection device 20 to collect dirt, without being limited by the internal space of the base station 10. Users no longer need to maintain the dust collection device 20 frequently (e.g., cleaning the dirt from it), thus reducing maintenance frequency and user burden. Furthermore, because the dust collection device 20 adopts a modular design, it is independent of the base station 10, allowing users to choose whether to equip it based on actual needs.

[0096] The dust collection device 20 includes a main body 21 and a dust collection bin 231, which is used to store and recycle dirt. The dust collection bin 231 is detachably connected to the main body 21 of the dust collection device 20. When the dust collection bin 231 needs to be cleaned, the user removes the dust collection bin 231 from the main body 21 to clean it. After cleaning, the dust collection bin 231 is reinstalled back into the main body 21. Traditional base stations 10 typically use dust bags to collect waste, and dust bags, as consumables, undoubtedly increase the user's operating costs. In this application scenario, the dust collection bin 231 is reusable, replacing the dust bag and reducing the user's operating costs.

[0097] The dust collection bin 231 has a first bin locking tongue 2331 and a second bin locking tongue 2332. The dust collection bin 231 also includes a handle 2341, a connecting rod 2342, a first moving part 23431, and a second moving part 23432. When the dust collection bin 231 needs to be cleaned, the user engages the handle 2341 to rotate relative to the bin body 2311. The handle 2341 drives the connecting rod 2342 to rotate, which in turn drives the first moving part 23431 and the second moving part 23432 to move towards each other. Simultaneously, this causes the first bin locking tongue 2331 and the second bin locking tongue 2332 to disengage from their respective locking slots 235, allowing the user to remove the dust collection bin 231 from the device body 21. The lid 2312 of the dust collection bin 231 is provided with a first lid locking tongue 2361 and a second lid locking tongue 2362. A first lid latch 2361 is provided on the side of the lid 2312 that is not connected to the barrel body 2311, and second lid latches 2362 are provided on the other two sides of the lid 2312 that are not connected to the barrel body 2311, that is, the lid 2312 and the barrel body 2311 are locked together on three sides. The lid 2312 is also provided with a first movable member 23811 and a second movable member 23812. The first lid latch 2361 is located on the first movable member 23811, and the second lid latch 2362 is located on the second movable member 23812. When the dust collection bin 231 needs to be cleaned, the user engages the first movable component 23811 via the latch 23816, causing the first movable component 23811 to disengage the first cover latch 2361 from the corresponding fixing groove 237. As the first movable component 23811 moves, the linkage column 2382 moves along the linkage groove 2383, causing the second movable component 23812 to move synchronously, thereby disengaging the second cover latch 2362 from the corresponding fixing groove 237, achieving three-sided unlocking. At this time, the cover 2312 is allowed to rotate away from the opening to open it, allowing the dirt stored in the collection chamber 2314 of the bin body 2311 to be discharged through the opening, achieving the purpose of cleaning the dust collection bin 231. After the dust collection bin 231 is cleaned, the user drives the cover 2312 to rotate towards the opening to close it, and then the user reinstalls the dust collection bin 231 back into the device body 21.

[0098] Application Scenario 2:

The dust collection device 20 collects dirt from the cleaning device via the base station 10. In this application scenario, the dust collection device 20 is externally connected to the base station 10, meaning it is located outside the base station 10 rather than integrated inside. This allows for a larger volume of dust collection device 20 to collect dirt, without being limited by the internal space of the base station 10. Users no longer need to maintain the dust collection device 20 frequently (e.g., cleaning the dirt from it), thus reducing maintenance frequency and user burden. Furthermore, because the dust collection device 20 adopts a modular design, it is independent of the base station 10, allowing users to choose whether to equip it based on actual needs.

[0100] The dust collection device 20 includes a main body 21 and a dust collection bin 231, which is used to store and recycle dirt. The dust collection bin 231 is detachably connected to the main body 21 of the dust collection device 20. When the dust collection bin 231 needs to be cleaned, the user removes the dust collection bin 231 from the main body 21 to clean it. After cleaning, the dust collection bin 231 is reinstalled back into the main body 21. Traditional base stations 10 typically use dust bags to collect waste, and dust bags, as consumables, undoubtedly increase the user's operating costs. In this application scenario, the dust collection bin 231 is reusable, replacing the dust bag and reducing the user's operating costs.

[0101] The dust collection bin 231 has a first bin locking tongue 2331 and a second bin locking tongue 2332. The dust collection bin 231 also includes a handle 2341, a connecting rod 2342, a first moving part 23431, and a second moving part 23432. When the dust collection bin 231 needs to be cleaned, the user engages the handle 2341 to rotate relative to the bin body 2311. The handle 2341 drives the connecting rod 2342 to rotate, which in turn drives the first moving part 23431 and the second moving part 23432 to move towards each other. Simultaneously, this causes the first bin locking tongue 2331 and the second bin locking tongue 2332 to disengage from their respective locking slots 235, allowing the user to remove the dust collection bin 231 from the device body 21. The lid 2312 of the dust collection bin 231 is provided with a first lid locking tongue 2361 and a second lid locking tongue 2362. A first lid latch 2361 is provided on the side of the lid 2312 that is not connected to the barrel body 2311, and second lid latches 2362 are provided on the other two sides of the lid 2312 that are not connected to the barrel body 2311, that is, the lid 2312 and the barrel body 2311 are locked together on three sides. The lid 2312 is also provided with a first movable member 23811 and a second movable member 23812. The first lid latch 2361 is located on the first movable member 23811, and the second lid latch 2362 is located on the second movable member 23812. When the dust collection bin 231 needs to be cleaned, the user engages the first movable component 23811 via the latch 23816, causing the first movable component 23811 to disengage the first cover latch 2361 from the corresponding fixing groove 237. As the first movable component 23811 moves, the linkage column 2382 moves along the linkage groove 2383, causing the second movable component 23812 to move synchronously, thereby disengaging the second cover latch 2362 from the corresponding fixing groove 237, achieving three-sided unlocking. At this time, the cover 2312 is allowed to rotate away from the opening to open it, allowing the dirt stored in the collection chamber 2314 of the bin body 2311 to be discharged through the opening, achieving the purpose of cleaning the dust collection bin 231. After the dust collection bin 231 is cleaned, the user drives the cover 2312 to rotate towards the opening to close it, and then the user reinstalls the dust collection bin 231 back into the device body 21.
