Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a clean base station and a cleaning system. Background Technology

[0002] With the development of technology and the fast pace of life, using cleaning robots and other cleaning equipment for environmental cleaning not only improves cleaning efficiency but also frees up people's hands. Therefore, cleaning equipment on the market is currently very popular.

[0003] Current cleaning robots and other cleaning equipment can automatically perform functions such as mopping, sweeping, and wiping. Moreover, cleaning equipment is usually equipped with a cleaning base station. During the cleaning process, the cleaning equipment can wash and dry the mop, or return to the cleaning base station to collect dust, charge, and self-clean after completing the cleaning work.

[0004] During operation, cleaning equipment may clean surfaces that are wet, such as when cleaning a restroom. This water-sweeping can cause water to enter the dustbin of the cleaning equipment, resulting in moisture-laden impurities. After the cleaning equipment returns to the cleaning base station, the base station collects dust from the equipment. The impurities in the dustbin are then collected into dust bags in the base station's dust chamber. The moisture in these impurities can cause the dust bags to mold and develop an unpleasant odor, leading to a poor user experience. Utility Model Content

[0067] With the development of technology and the fast pace of life, using cleaning robots and other cleaning equipment for environmental cleaning not only improves cleaning efficiency but also frees up people's hands. Therefore, cleaning equipment on the market is currently very popular.

[0068] Current cleaning robots and other cleaning equipment can automatically perform functions such as mopping, sweeping, and wiping. Moreover, cleaning equipment is usually equipped with a cleaning base station. During the cleaning process, the cleaning equipment can wash and dry the mop, or return to the cleaning base station to collect dust, charge, and self-clean after completing the cleaning work.

[0069] During operation, cleaning equipment may clean surfaces with water, such as when cleaning a bathroom. This sweeping action can easily cause water to enter the dustbin of the cleaning equipment, resulting in moisture-laden impurities. After the cleaning equipment returns to the cleaning base station, the base station collects dust from the equipment. The impurities in the dustbin are then collected into a dust bag in the base station's dust chamber. The moisture in these impurities can cause the dust bag to mold and develop an unpleasant odor, leading to a poor user experience. The cleaning base station and cleaning system provided in this application embodiment can improve the above problems. The cleaning base station and cleaning system provided in this application embodiment can dry the impurities in the dust bag, reducing the possibility of mold and odor, and improving the user experience.

[0070] This application is described below with reference to the accompanying drawings and specific embodiments:

[0071] Figure 1 This paper shows a schematic diagram of the structure of a clean base station 100 provided in an embodiment of this application. Figure 2 This paper shows a first-view structural schematic diagram of the cleaning system 10 provided in an embodiment of this application. Figure 3 It shows Figure 1 The sectional view at point AA is as follows: Figure 1 , Figure 2 and Figure 3 As shown in the illustration, this application provides a cleaning base station 100, which is mainly used to place and accommodate cleaning equipment 200. It can charge, collect dust, clean, and dry the cleaning equipment 200. The cleaning base station 100 provided in this application embodiment can dry impurities in the dust bag 142, reducing the possibility of the dust bag 142 becoming moldy and smelly, and improving the user experience.

[0072] In this embodiment of the application, the cleaning base station 100 includes: a dust bin 110, a dust collecting fan 120, and a drying fan 130. The dust bin 110 has a dust collection chamber 112. The dust collecting fan 120 and the drying fan 130 are both connected to the dust collection chamber 112.

[0073] The dust bin 110 is the basic component for accommodating the dust bag 142. The dust bag 142 can be placed in the dust collection chamber 112 of the dust bin 110. The cleaning base station 100 also includes a dust collection channel 160 and a main body 170. The main body 170 is provided with a receiving chamber 172 for accommodating the cleaning equipment 200. The dust collection channel 160 has a first dust collection port 162 and a second dust collection port 164. The first dust collection port 162 is connected to the dust bin 110, and the dust bag 142 is connected to the first dust collection port 162. The second dust collection port 164 is connected to the receiving chamber 172. After the cleaning equipment 200 returns to the cleaning base station 100, the dust outlet of the dust box of the cleaning equipment 200 is connected to the second dust collection port 164, so that the impurities in the dust box can be recovered into the dust bag 142 through the dust collection channel 160.

[0074] Specifically, after the cleaning device 200 returns to the receiving cavity 172, a trigger unit can be provided in the receiving cavity 172, and a positioning detection element can be provided on the cleaning device 200. Of course, in some other embodiments, a trigger unit can be provided on the cleaning device 200, and a positioning detection element can be provided on the cleaning base station 100. The positions of the trigger unit and the positioning detection element are not limited.

[0075] Regardless of the setup, if the trigger unit activates the detection element, it indicates that the cleaning device 200 has returned to the receiving cavity 172 and the dust outlet of the dust box has successfully connected with the second dust collection port 164. At this point, the dust collection fan 120 can be turned on, creating negative pressure within the dust chamber 110. Impurities in the dust box of the cleaning device 200 are then collected into the dust bag 142 through the dust collection channel 160. For ease of description, the process of turning on the dust collection fan 120 to collect dust can be defined as the dust collection mode. In some embodiments, the user can periodically replace the dust bag 142 or remove the dust bag 142 from the dust chamber 110 to clean the impurities inside.

[0076] In some embodiments, the dust collecting fan 120 and the drying fan 130 can be mounted on the main body 170. The drying fan 130 communicates with the receiving cavity 172 and can guide gas into the receiving cavity 172. In some embodiments, the main body 170 includes a cleaning disc 174 and a main housing 176. The cleaning disc 174 and the main housing 176 are connected and form the receiving cavity 172. The dust collecting fan 120, the drying fan 130, etc., are mounted inside the main housing 176.

[0077] The cleaning device 200 includes cleaning components such as a mop, a roller brush, and side brushes. During the cleaning process, the mop can wash the surface. After the mop becomes dirty, it can return to the cleaning base station 100, where the cleaning tray 174 washes the mop. After washing, the mop can continue cleaning. After the cleaning device 200 completes cleaning and returns to the receiving cavity 172, the cleaning base station 100 can begin washing the mop. After washing, the mop can be dried by the drying fan 130. Specifically, the drying fan 130 is activated, allowing airflow to blow into the receiving cavity 172, which dries the mop and / or the cleaning tray 174.

[0078] In some embodiments, when the drying fan 130 is working, since the drying fan 130 is connected to the dust collection chamber 112, after the drying fan 130 is working, a negative pressure is formed in the dust collection chamber 112, which can form an airflow towards the drying fan 130 in the dust collection chamber 112. The airflow flows towards the mop and / or cleaning tray 174 of the cleaning device 200 under the action of the drying fan 130, thereby drying the mop and cleaning tray 174.

[0079] Since the drying fan 130 is also connected to the dust collection chamber 112, a negative pressure is formed in the dust collection chamber 112 after the drying fan 130 is working. This creates an airflow towards the drying fan 130 within the dust collection chamber 112, allowing the airflow to carry away the moisture in the dust bag 142. This also helps to dry the dust chamber 110 to a certain extent, reducing the problem of mold and odor caused by moisture in the impurities. It should be noted that the dry dust chamber 110 mentioned in this application refers to the dust bag 142 within the dry dust chamber 110 (drying the dust bag 142 and / or the impurities in the dust bag 142). For ease of description, the above mode is defined as the drying mode, which includes at least one of the dry dust chamber 142, the cleaning disc 174, and the mop. In short, the working state when the dust collection fan 120 is turned on is the dust collection mode, and the working state when the drying fan 130 is turned on is the drying mode.

[0080] In some embodiments, the cleaning base station 100 further includes a drying component 150, which is connected to the drying fan 130 and disposed near the receiving cavity 172. When the drying fan 130 is working, if the drying component 150 is turned on, a negative pressure is formed in the dust collection cavity 112, which can form an airflow towards the drying fan 130 in the dust collection cavity 112. The airflow flows to the drying component 150 under the action of the drying fan 130, and after being heated by the drying component 150, it flows to the mop and / or cleaning tray 174 of the cleaning device 200, thereby drying the mop and cleaning tray 174.

[0081] If the drying unit 150 is not turned on, the airflow flows to the drying unit 150 under the action of the drying fan 130. The drying unit 150 does not heat up, and the unheated gas flows to the mop and / or cleaning tray 174 of the cleaning device 200, thereby drying the mop and cleaning tray 174.

[0082] In other words, the cleaning disc 174 and / or the mop have two drying modes: air drying mode and dry drying mode. In air drying mode, only the drying fan 130 is turned on, while in dry drying mode, both the drying fan 130 and the drying component 150 are turned on.

[0083] In addition, a heating element 190 can be installed in the dust collection chamber 112 to dry the dust bag 142. Specifically, the cleaning base station 100 also includes a heating element 190, which is installed in the dust collection chamber 112 to heat the dust bag 142 installed in the dust collection chamber 112. The drying effect of the dust chamber 110 can be improved by the combined action of the heating element 190 and the drying fan 130.

[0084] In other words, the drying modes of dust chamber 110 include air-drying mode and dry-roasting mode. When only the drying fan 130 is turned on, it is in air-drying mode. When both the heating element 190 and the drying fan 130 are turned on, it is in dry-roasting mode.

[0085] Of course, in some other embodiments, the heating element 190 may not be provided in the dust collection chamber 112, and the dust chamber 110 may be dried by air drying alone.

[0086] Figure 4 A schematic diagram of the structure of the heating element 190 and the dust bag 142 is shown, as follows. Figure 4 As shown, in some embodiments, the heating element 190 includes a heating part 192 and a heat-conducting plate 194. The heat-conducting plate 194 has a fixed surface 1942 and a heat-conducting surface 1944 facing away from each other. The heating part 192 is disposed on the heat-conducting surface 1944, and the dust bag 142 is placed on the fixed surface 1942.

[0087] The dust bag 142 can be placed on the fixed surface 1942, and the heating part 192 can be turned on, transferring heat to the dust bag 142 through the heat-conducting plate 194. This arrangement can increase the contact area between the dust bag 142 and the heat-conducting plate 194, thereby improving the drying effect.

[0088] In summary, the drying mode includes four separate modes. Since the drying fan 130 acts on both the dust bin 110 and the receiving cavity 172, several different operating states will be listed below:

[0089] With only the drying fan 130 activated, the dust bin 110 is in air-drying mode, and the mop and / or washing tray 174 is also in air-drying mode. With the drying fan 130 activated and the drying assembly 150 turned on, the dust bin 110 is in air-drying mode, and the mop and / or washing tray 174 is in drying mode. With the drying fan 130 activated and the heating element 190 turned on, the dust bin 110 is in drying mode, and the mop and / or washing tray 174 is in air-drying mode. With the drying fan 130 activated, the heating element 190 turned on, and the drying assembly 150 turned on, the dust bin 110 is in drying mode, and the mop and / or washing tray 174 is also in drying mode.

[0090] In this embodiment, since the drying fan 130 is connected to the dust collection chamber 112, airflow can also be formed in the dust collection chamber 112 after the drying fan 130 is started. There is no need to set up a separate dust chamber 110 drying structure. The dust chamber 110 can be dried by using the cleaning base station 100 and the drying fan 130. This can reduce the number of parts of the entire cleaning base station 100, making the cleaning base station 100 more compact and miniaturized as much as possible. It can also reduce the manufacturing cost of the cleaning base station 100 to a certain extent.

[0091] Regardless of the drying mode, the gas flow direction in the dust collection fan 120 and the drying fan 130 is the same. The following is a detailed introduction to the arrangement, specific structure, and how to achieve different gas flow directions of the dust collection fan 120 and the drying fan 130.

[0092] Figure 5 It shows Figure 3 A magnified view of a section at point I, as shown below. Figure 5 As shown, in some embodiments, the dust collection fan 120 is connected to the dust bin 110, and the drying fan 130 is connected to the dust collection fan 120.

[0093] Since both the dust collecting fan 120 and the drying fan 130 are connected to the dust collection chamber 112 in the dust bin 110, the connection can be direct or indirect. In some embodiments, the dust collecting fan 120 is connected to the dust bin 110, that is, the dust collecting fan 120 is directly connected to the dust collection chamber 112, and the drying fan 130 is connected to the dust collecting fan 120, and the drying fan 130 is connected to the dust collection chamber 112 through the dust collecting fan 120.

[0094] During the dust collection process, the dust box of the cleaning equipment 200 contains impurities. In order to draw these impurities from the dust collection channel 160 into the dust bag 142, the dust collection fan 120 needs to operate at a relatively high speed to create a large negative pressure within the dust chamber 110. Only after the negative pressure reaches a certain threshold can the impurities in the cleaning equipment 200 be recovered. The dust collection fan 120 is directly connected to the dust chamber 110, allowing it to communicate directly with the dust collection cavity 112. The dust collection fan 120 can directly act on the dust collection cavity 110, thereby reducing the air resistance within the dust collection cavity 112 and enabling the impurities in the cleaning equipment 200 to be smoothly recovered into the dust bag 142, thus improving the dust collection efficiency.

[0095] Because the dust collection fan 120 rotates at a relatively high speed in dust collection mode, in order to create a large negative pressure in the dust bin 110, the dust bin 110 should be as closed as possible except for the connection points with the dust collection channel 160 and the dust collection fan 120. The drying fan 130 is connected to the dust collection fan 120 but not directly connected to the dust bin 110. This reduces the number of openings in the dust bin 110 and ensures that a large negative pressure can be created in the dust bin 110 in dust collection mode, thereby enabling impurities to be recovered into the dust bin 110.

[0096] Furthermore, during the drying process in the dust chamber 110 (dust bag 142), if the rotation speed of the drying fan 130 is too high, the airflow will be too fast when passing through the drying assembly 150, resulting in insufficient contact time with the drying assembly 150. This will prevent the airflow from being heated to a high temperature, leading to poor mop drying performance. In drying mode, the drying fan 130 rotates at a lower speed. The drying fan 130 is connected to the dust collection fan 120, so that the airflow in the dust collection chamber 112 first passes through the dust collection fan 120 before entering the drying fan 130. The airflow in the dust collection chamber 112 slows down after passing through the dust collection fan 120, ensuring that airflow passes through the dust bag 142 while allowing the gas to slowly pass through the drying assembly 150, increasing the contact time between the gas and the drying assembly 150, thereby improving the drying effect.

[0097] In some embodiments, the dust collecting fan 120 is disposed between the dust bin 110 and the drying fan 130. In some embodiments, the dust bin 110 and the drying fan 130 may be disposed at opposite ends of the axial direction of the dust collecting fan 120. The fact that the dust bin 110 and the drying fan 130 are disposed at opposite ends of the dust collecting fan 120 allows the gas flow direction within the dust collecting fan 120 to be different in dust collecting mode and drying mode, enabling the dust collecting mode and drying mode to be independent and unaffected by each other.

[0098] Figure 6 An exploded view of the dust collection fan 120 is shown. Figure 7 A schematic diagram of the structure of part of the first housing 121 of the dust collection fan 120 is shown. Figure 8 This diagram shows the structure of the dust collection fan 120 and the drying fan 130 in dust collection mode. Figure 9 It shows Figure 8 Sectional view at point BB. Figure 10 The diagram shows the structure of the dust collection fan 120 and the drying fan 130 in either air-drying or drying mode. Figure 11 It shows Figure 10 A sectional view at point CC, as shown Figures 6-11 As shown, in some embodiments, the dust collection fan 120 includes a first housing 121 and a first fan 123. The first housing 121 is installed in the dust chamber 110, and the first fan 123 is disposed in the first housing 121. The first housing 121 has a first air inlet 1211, a first air outlet 1213 and a connection port 1214. The first air inlet 1211 communicates with the dust collection chamber 112, and the connection port 1214 communicates with the drying fan 130.

[0099] The first fan 123 is disposed in the first housing 121. The first housing 121 is generally cylindrical and has two end faces and a side face connecting the two end faces. The first air inlet 1211 is disposed on one end face, the connection port 1214 is disposed on the other end face of the first housing 121, and the first air outlet 1213 is disposed on the side face of the first housing 121.

[0100] like Figure 7 As shown, in some embodiments, the first housing 121 has a first mounting cavity 1215 and a noise reduction cavity 1216 that are interconnected. The first fan 123 is installed in the first mounting cavity 1215, and the first air outlet 1213 is connected to the noise reduction cavity 1216. The dust collection fan 120 also includes a first noise reduction component 126, which is disposed in the noise reduction cavity 1216.

[0101] In dust collection mode, the first fan 123 will operate at a higher speed, resulting in a larger airflow in the dust bin 110 and the first housing 121. The first noise reduction component 126 is installed in the noise reduction cavity 1216, which can reduce the noise extending from the first air outlet 1213 to a certain extent, thus achieving a noise reduction effect.

[0102] In some embodiments, the first noise reduction element 126 may be disposed between the first mounting cavity 1215 and the first air outlet 1213, so that the gas can pass through the first noise reduction element 126 as much as possible before flowing out of the first air outlet 1213, thereby reducing the noise at the first air outlet 1213 as much as possible and improving the user experience.

[0103] In some embodiments, the first noise reduction element 126 may be noise reduction foam.

[0104] Since a first noise reduction component 126 is provided inside the noise reduction cavity 1216, in order to fix the first noise reduction component 126, a partition 1217 can be provided between the first mounting cavity 1215 and the noise reduction cavity 1216. Multiple connecting holes 1218 are provided on the partition 1217, and the first mounting cavity 1215 and the noise reduction cavity 1216 are connected through the multiple connecting holes 1218.

[0105] In some embodiments, the first fan 123 can be a centrifugal fan, the first air inlet 1211 is located on the air inlet side of the first fan 123, and the connection port 1214 is located on the air outlet side of the first fan 123. After the first fan 123 is turned on, since the first air inlet 1211 is connected to the dust collection chamber 112, the gas in the dust bin 110 will flow to the first air inlet 1211, so that a negative pressure is formed in the dust bin 110. Since the first air outlet 1213 is located on the air outlet side of the first fan 123, after the first fan 123 is started, the gas will preferentially flow out from the first air outlet 1213.

[0106] Of course, if the opening of the first air outlet 1213 is small and the rotation speed of the first fan 123 is high, some gas will also flow out from the first air outlet 1213. In dust collection mode, most or all of the gas still flows out from the first air outlet 1213. That is, in dust collection mode, the gas flow direction inside the dust collection fan 120 is as follows: Figure 9 As shown by the hollow arrow, the air enters the first housing 121 from the dust bin 110 through the first air inlet 1211, and then flows out from the first air outlet 1213 and the connection port 1214 respectively.

[0107] In drying mode, the first fan 123 is stopped and not working. Since the dust collection fan 120 is connected to the connection port 1214, the gas in the dust bin 110 enters the first housing 121 through the first air inlet 1211, and then enters the drying fan 130 through the connection port 1214. That is, in drying mode, the gas flow direction in the dust collection fan 120 is as follows: Figure 11 As shown by the hollow arrow, the air enters the first housing 121 from the dust bin 110 through the first air inlet 1211, and then flows to the drying fan 130 through the connection port 1214.

[0108] Figure 12 An exploded view of the dust collection door 125 and the first housing 121 is shown. Figure 13 It shows Figure 11 A magnified view of a section at point II, as shown below. Figure 12 and Figure 13 As shown, since the first air outlet 1213 is located on the side of the first housing 121, in the drying mode, if the first air outlet 1213 is not closed, air will still enter through the first air outlet 1213, which will reduce the amount of gas entering the first housing 121 from the dust bin 110, which is not conducive to the drying of the dust bin 110. In some embodiments, the dust collecting fan 120 also includes a dust collecting door 125, which is connected to the first housing 121, and the dust collecting door 125 opens or closes the first air outlet 1213.

[0109] In dust collection mode, the dust collection door 125 opens the first air outlet 1213, allowing some or all of the gas to be discharged from the first air outlet 1213. In drying mode, the dust collection door 125 closes the first air outlet 1213, ensuring that all the gas comes from inside the dust chamber 110, thus guaranteeing the drying effect on the dust chamber 110 (dust bag 142).

[0110] In some embodiments, the dust collection door 125 is disposed outside the first housing 121. With the dust collection door 125 disposed outside the first housing 121, in drying mode, the negative pressure of the first housing 121 can be used to close the dust collection door 125. In dust collection mode, since the first air outlet 1213 is located on the air outlet side of the first fan 123, the gas can be used to blow open the dust collection door 125.

[0111] Specifically, in some embodiments, the dust collection door 125 can be an elastic door, with one end connected to the first housing 121. The end of the dust collection door 125 connected to the first housing 121 is a fixed end, and the other end is a free end. In dust collection mode, as the gas inside the first housing 121 flows towards the first air outlet 1213, the free end of the dust collection door 125 moves away from the first housing 121, opening the first air outlet 1213. In drying mode, as the gas in the first housing 121 flows out of the connection port 1214 from the first air inlet 1211, under negative pressure, the free end of the dust collection door 125 moves towards the first housing 121, allowing the dust collection door 125 to fit against the first housing 121, thereby closing the first air outlet 1213.

[0112] In the drying mode, since the dust collection door 125 is closed by the negative pressure inside the first housing 121, the greater the flow rate from the first air inlet 1211 to the connection port 1214, the tighter the dust collection door 125 is pressed, and the better the sealing effect, ensuring that the gas flows from the connection port 1214 to the drying fan 130 and then to the cleaning tray 174 and the mop.

[0113] When neither the dust collection fan 120 nor the drying fan 130 is working, the dust collection door 125 is in a naturally closed state. That is, when neither the dust collection fan 120 nor the drying fan 130 is turned on, the dust collection door 125 can close the first air outlet 1213 under its own elasticity, which can prevent external impurities from entering the first housing 121 and affecting the operation of the first fan 123 to a certain extent.

[0114] Regarding the method of fixing the dust collection door 125 to the first housing 121, a first positioning part 1219 can be provided on the first housing 121, and a second positioning part 1252 can be provided on the dust collection door 125, with the first positioning part 1219 and the second positioning part 1252 fixedly connected. Specifically, the fixing member 127 can be a screw, with a threaded hole provided on the first positioning part 1219 and a through hole provided on the second positioning part 1252, and the fixing member 127 passing through the through hole and the threaded hole. Of course, in some other embodiments, the first positioning part 1219 can be fixed to the second positioning part by snap-fit ​​or other methods, and the specific fixing method is not limited.

[0115] Figure 14 An exploded view of the drying fan 130 is shown, as follows: Figure 14As shown, in some embodiments, the drying fan 130 includes a connecting duct 132 and a second fan 134. The second fan 134 is installed in the connecting duct 132. The connecting duct 132 has a second air inlet 1322 and a second air outlet 1324. The second air inlet 1322 is connected to the dust collection fan 120, and the second air outlet 1324 is connected to the drying assembly 150.

[0116] The second air inlet 1322 is connected to the connection port 1214, and the second air outlet 1324 is connected to the drying component 150. When the second fan 134 is working, the gas in the first housing 121 enters the second fan 134 through the connection port 1214 and the second air inlet 1322, and then flows to the drying module through the connecting air duct 132.

[0117] Figure 15 An exploded view of the dust collection fan 120 and the drying fan 130 is shown, as follows: Figure 15 As shown, in some embodiments, the cleaning base station 100 further includes a second noise reduction component 144, which is disposed between the dust collection fan 120 and the drying fan 130. Specifically, the second noise reduction component 144 is disposed between the connection port 1214 and the second air inlet 1322, which can also reduce noise in the drying mode to a certain extent and improve the user experience.

[0118] To improve the sealing performance of the connecting duct 132 and the first housing 121, a first sealing element 146 can be provided between the connecting duct 132 and the first housing 121 to seal the gap between the connecting duct 132 and the first housing 121.

[0119] It should be noted that in some embodiments, the connecting air duct 132 is generally elongated, and the length direction of the connecting air duct 132 is generally perpendicular to the axis of the first housing 121. The drying group is located below the second fan 134, and the first fan 123 and the second fan 134 are located at the same height, with the first fan 123 located in front of the second fan 134. This arrangement allows for a more compact structural layout of the entire cleaning base station 100.

[0120] Figure 16 A top view of a portion of the structure of the clean base station 100 provided in an embodiment of this application is shown. Figure 17 It shows Figure 16 A sectional view at point DD, as shown Figure 16 and Figure 17As shown, in some embodiments, the dust bin 110 is provided with an air supply port 114, and the cleaning base station 100 also includes an air damper assembly 180, which is connected to the dust bin 110. When the dust collection fan 120 is working, the air damper assembly 180 closes the air supply port 114, and when the drying fan 130 is working, the air damper assembly 180 opens the air supply port 114.

[0121] The damper assembly 180 is located outside the first housing 121. In dust collection mode, the dust collection fan 120 (first fan 123) rotates at a high speed, creating a large negative pressure within the dust chamber 110, thereby recovering impurities from the cleaning equipment 200 into the dust bag 142. In air-drying or drying mode, the dust collection fan 120 is turned off, the drying fan 130 is turned on, and the dust bag 142 is connected to the dust collection channel 160. However, the drying fan 130 rotates at a lower speed, making it difficult for gas to enter the dust chamber 110 from the dust collection channel 160. To ensure sufficient gas can enter the dust chamber 110, a makeup air inlet 114 can be provided on the dust chamber 110. When the dust collection fan 120 is operating (dust collection mode), the makeup air inlet 114 is closed. When the drying fan 130 is working (drying mode), the air inlet 114 is opened, ensuring that there is gas flowing in the dust chamber 110 in the air drying mode or baking mode, so that the airflow can carry away the moisture in the dust chamber 110 and dry the dust chamber 110.

[0122] Figure 18 It shows Figure 14 A magnified view of a section at point II. Figure 19 An exploded view of a portion of the structure of the clean base station 100 is shown, such as... Figure 18 and Figure 19 As shown, regarding the specific structure of the damper assembly 180, in some embodiments, the damper assembly 180 includes a damper 182 and an elastic member 184, with the elastic member 184 connecting the damper 182 and the dust chamber 110. Because the elastic member 184 has a certain degree of elasticity, it can support the damper 182. When neither the integrated fan nor the drying fan 130 is turned on, the elastic member 184 supports the damper 182, creating a certain gap between the damper 182 and the air intake 114, allowing the air intake 114 to open.

[0123] In dust collection mode, due to the very high rotational speed of the dust collection fan 120, the negative pressure generated within the dust chamber 110 exceeds the restoring force of the elastic element, causing the elastic element 184 to compress. This compresses the damper 182, moving it closer to the dust chamber 110 until the damper 182 closes the air intake port 114. In other words, in dust collection mode, the damper 182 is closed by the negative pressure within the dust chamber 110.

[0124] In the drying mode, when the speed of the drying fan 130 is relatively low, the negative pressure formed in the dust chamber 110 is less than the restoring force of the elastic element 184. The elastic element 184 does not deform or deforms slightly, so that the damper 182 and the dust chamber 110 always maintain a certain distance, so that the damper 182 always opens the air supply port 114. The gas can enter the dust chamber 110 through the air supply port 114, and then enter the connecting air duct 132 through the first housing 121.

[0125] In order to improve the stability of the connection between the elastic element 184 and the damper 182, a fixing groove 1821 can be provided on the damper 182, and the elastic element 184 can be placed in the fixing groove 1821.

[0126] In some embodiments, the damper assembly 180 further includes a guide member 186, an elastic member 184 sleeved on the guide member 186, and a damper 182 having a mounting hole 1823, through which the guide member 186 passes. The elastic member 184 can be a spring, sleeved on the guide member 186, which passes through the mounting hole 1823, so that the damper 182 is also sleeved on the guide member 186. The guide member 186 can guide the movement of the damper 182, thereby improving the stability of the damper 182 during movement.

[0127] In some embodiments, the guide member 186 may include a guide portion 1862 and a stop portion 1864. The guide portion 1862 is connected to the dust bin 110 and the stop portion 1864, respectively. Specifically, one end of the guide portion 1862 may be connected to the dust bin 110, and the other end may be connected to the stop portion 1864. The elastic member 184 and the damper 182 are sleeved on the guide portion 1862. The elastic member 184 and the damper 182 are disposed between the stop portion 1864 and the dust bin 110. The damper 182 is disposed between the elastic member 184 and the stop portion 1864. The stop portion 1864 can limit the maximum upward movement distance of the damper 182, reducing the risk of the damper 182 falling off the guide portion 1862.

[0128] In some embodiments, the damper assembly 180 further includes a second seal 187, which is used to seal the gap between the damper 182 and the dust bin 110 when the damper 182 closes the air supply port 114. The second seal 187 can be fixed to the damper 182 or the dust bin 110. The fixed position of the second seal 187 is not limited, as long as it can seal the gap between the damper 182 and the dust bin 110.

[0129] In some embodiments, the stop portion 1864 and the guide portion 1862 can be detachably connected, thereby facilitating the installation and replacement of the damper 182. Regarding the detachable connection method, the stop portion 1864 can be a screw, and a threaded hole is provided on the guide portion 1862, with the screw engaging with the threaded hole.

[0130] The working principle of the cleaning base station 100 provided in this application embodiment is as follows: Since the cleaning base station 100 has a variety of different gas flow directions in different working modes, the gas flow directions in the cleaning base station 100 in the dust collection mode and the drying mode will be described below.

[0131] Figure 20 A schematic diagram of the gas flow direction of the cleaning device 200 in dust collection mode is shown. Figure 20 Hollow arrows indicate the direction of gas flow, such as Figure 20 As shown, in the dust collection mode: the first fan 123 is started and the second fan 134 is turned off. The first fan 123 rotates at a very high speed, and the negative pressure formed in the dust bin 110 is greater than the elastic restoring force, which causes the elastic element 184 to be compressed, driving the damper 182 to move closer to the dust bin 110 until the damper 182 closes the air supply port 114.

[0132] Since the first air inlet 1211 is connected to the dust collection chamber 112, the gas in the dust bin 110 flows to the first air inlet 1211, creating a negative pressure inside the dust bin 110. A negative pressure is also created inside the dust collection channel 160. Impurities in the dust box of the cleaning equipment 200 are collected into the dust bag 142 through the dust collection channel 160. The gas inside the first housing 121 flows out from the first air outlet 1213 and the connection port 1214.

[0133] Figure 21 A schematic diagram of the gas flow direction of the cleaning device 200 in drying mode is shown. Figure 21 The hollow arrows indicate the gas flow direction. As shown in 21, in the drying mode: the first fan 123 is off and the second fan 134 is on, creating a negative pressure in the dust chamber 110. Since the second fan 134 rotates at a lower speed, the damper 182 is opened, and the gas enters the dust chamber 110 through the air inlet 114, then enters the first housing 121, passes through the first housing 121, enters the second fan 134, connects to the air duct 132, and flows to the second air outlet 1324.

[0134] In summary, since the drying fan 130 is connected to the dust collection chamber 112, airflow can also be formed in the dust collection chamber 112 after the drying fan 130 is started. There is no need to set up a separate dust bin 110 drying structure. The dust bin 110 can be dried by using the cleaning base station 100 and the drying fan 130. This can reduce the number of parts in the entire cleaning base station 100, making the cleaning base station 100 more compact and miniaturized as much as possible. It can also reduce the manufacturing cost of the cleaning base station 100 to a certain extent.

[0135] Figure 22 This illustration shows a second-view structural diagram of the cleaning system 10 provided in an embodiment of this application, as shown below. Figure 22 As shown, based on the same inventive concept, this application also provides a cleaning system 10, including a cleaning device 200 and the aforementioned cleaning base station 100. The cleaning base station 100 can house the cleaning device 200 and can charge, collect dust, clean, and dry the cleaning device 200.
