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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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 2271, 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 2271, 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 2272, 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 2272. 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 2271 is located on the side of the first sub-channel 2223a closer to the receiving cavity 2221, while the second exhaust seal 2272 is located on the side of the first sub-channel 2223a away from the receiving cavity 2221. The first exhaust seal 2271 and the second exhaust seal 2272 cooperate to seal the first sub-channel 2223a.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] The technical solutions provided in the embodiments of this application will be described below in conjunction with specific application scenarios.

[0066] Application Scenario 1:

[0067] 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.

[0068] The dust collection device 20 includes a main body 21. The dust collection device 20 also includes a negative pressure component 22, which is disposed within the main body 21. The dust collection device 20 further includes a dust collection component 23, which is disposed within the main body 21 and connected to the negative pressure component 22.

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 can be reused, replacing the dust bag and reducing the user's operating costs.

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.

[0073] 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 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.
