Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more specifically to a cleaning system. Background Technology

[0002] With the development of household cleaning equipment and the increasing demands of home users for cleaning results, floor scrubbers have become increasingly popular among consumers due to their high efficiency, convenience, environmental friendliness, and ability to be used both wet and dry. Floor scrubbers are typically equipped with a base station, which can automatically clean and maintain the machine, such as automatically adding water, charging, rinsing the wastewater tank, and discharging wastewater, thus further freeing up the user's hands.

[0003] In existing base stations, filters are typically installed in the sewage troughs to prevent garbage from entering the sewer system. However, wet garbage trapped in the filters can easily produce odors. To solve this problem, a separate hot air drying system could be added to the base station to dry the garbage in the filters. However, adding an extra hot air drying system to the base station is both costly and complex, and difficult to maintain later. Utility Model Content

[0004] This disclosure provides a cleaning system to address the problems existing in the prior art.

[0005] According to a first aspect of this disclosure, a cleaning system is provided, comprising:

[0006] A cleaning device, comprising a wastewater tank, a main motor, an air duct assembly, a floor brush assembly, and a body that cooperates with the floor brush assembly; the wastewater tank has a drain outlet at the bottom, and the main motor has an air outlet; the air duct assembly has an air duct inlet and an air duct outlet, and the air duct inlet is connected to the air outlet;

[0007] A base station is provided for docking the cleaning equipment; the base station is equipped with a sewage discharge trough, which is configured to connect with the sewage discharge port to discharge the dirt collected by the cleaning equipment.

[0008] When the cleaning equipment is docked at the base station, the air duct outlet is configured to connect to the sewage trough, and the airflow from the air outlet is configured to be blown into the sewage trough through the air duct assembly.

[0009] One beneficial effect of this disclosure is that by setting up an air duct assembly, the air outlet of the main motor can be connected to the sewage tank, thereby enabling drying and sterilization of the sewage tank. This disclosure eliminates the need for an additional drying mechanism on the base station; instead, it utilizes the existing main motor on the cleaning equipment and provides a novel drying air path by adding an air duct assembly, thus improving the utilization rate of the main motor's air outlet. Compared to the solution of adding an additional drying mechanism to the base station, this disclosure offers lower drying costs, lower system complexity, easier maintenance of the added air duct assembly, and better sterilization of the sewage tank.

[0027] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0032] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0033] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0034] refer to Figure 1 and Figure 2 This disclosure provides a cleaning system, including a cleaning device 1 and a cleaning base station 2. For ease of description, the direction of travel of the cleaning device 1 will be referred to as "forward" in the following description, with reference to... Figure 1 The direction of the view, that is, the direction of travel of cleaning equipment 1. Figure 1 The right side. From another perspective, we can also consider the user's perspective, with the side of the cleaning device 1 furthest from the user designated as the front side and the side facing the user designated as the rear side.

[0035] The cleaning device 1 disclosed herein can be a handheld cleaning device, such as a handheld cleaning machine, a handheld wet vacuum cleaner, a handheld floor scrubber, a handheld fabric cleaner, or other handheld cleaning devices well known to those skilled in the art. It can also be a floor cleaning robot, a sweeping and mopping robot, or other self-moving cleaning devices well known to those skilled in the art. This embodiment uses a handheld floor scrubber as an example of the cleaning device 1. Figure 1 As shown, the cleaning equipment includes a floor brush assembly 11 and a body 12 that cooperates with the floor brush assembly 11. The floor brush assembly 11 is configured to clean the work surface. Specifically, the floor brush assembly 11 is rotatably connected to the body 12. When the cleaning equipment 1 is parked on the work surface or cleaning the work surface, the floor brush assembly 11 remains in contact with the work surface. Furthermore, a handheld part 10 can be provided on the top of the body 12. After the cleaning equipment 1 is turned on, the user can hold the handheld part 10 to tilt the body 12 and push and pull it back and forth, causing the floor brush assembly 11 to move on the work surface to clean the dirt on the work surface. When the user holds the handheld part 10 to make the body 12 upright, the cleaning equipment 1 stops working.

[0036] In one embodiment of this disclosure, such as Figure 4As shown, the floor brush assembly 11 includes a floor brush housing 111 and a roller brush 112 rotatably connected to the floor brush housing 111. The roller brush 112 is used to clean the work surface. The outer surface of the roller brush 112 may be provided with cleaning cotton, brush bristles, or other cleaning components, thereby allowing the roller brush 112 to wet-mop the work surface during rotation. The roller brush 112 is rotatably connected to one side of the floor brush housing 111, and a traveling wheel 114 may be provided on the other side. The traveling wheel 114 rotates when the user applies a forward or backward pushing force, or when the cleaning device 1 of this disclosure is a cleaning robot, the traveling wheel 114 rotates under its own driving force, allowing the cleaning device 1 to move on the work surface.

[0037] The cleaning device 1 also includes a wastewater tank 13, which can be mounted on the main body 12. Specifically, the wastewater tank 13 can be positioned at the rear of the main body 12, thereby helping to balance the center of gravity of the cleaning device 1. The wastewater tank 13 can be used to store dirt after cleaning, and a drain outlet 131 is provided at the bottom of the wastewater tank 13. In one embodiment of this disclosure, as... Figure 2 As shown, a suction channel 17 is provided on the cleaning equipment 1, and a suction port 113 communicating with the outside is provided on the floor brush assembly 11. The suction port 113 is configured to connect to the wastewater tank 13 through the suction channel 17. It is understood that the suction channel 17 may include more than one pipe; this disclosure refers to all pipes passing through the suction port 113 to the wastewater tank 13 as the suction channel 17, such as... Figure 2 As shown, in this embodiment, the flexible pipe connecting the floor brush assembly 11 and the body 12, as well as the structural pipe inside the body 12, are collectively referred to as the suction channel 17. In this disclosure, while cleaning with the floor brush assembly 11, the cleaned dirt can be sucked into the wastewater tank 13 through the suction port 113 and stored for subsequent centralized treatment.

[0038] Furthermore, the cleaning equipment 1 also includes a main motor 14, which can be mounted on the body 12 and specifically positioned above the wastewater tank 13. The main motor 14 has an air inlet and an air outlet, with the air inlet configured to communicate with the wastewater tank 13. This allows a negative pressure environment to be created within the wastewater tank 13 during operation of the main motor 14, under which dirt at the suction port 113 can be temporarily sucked into the wastewater tank 13.

[0039] In one specific embodiment of this disclosure, the air inlet of the main motor 14 is connected to the upper end of the sewage tank 13, and a filter device 133 may be provided at the upper end of the sewage tank 13. The gas drawn out from the sewage tank 13 needs to be filtered by the filter device 133 before flowing to the main motor 14. It is understood that the gas entering the sewage tank 13 along with the dirt carries solid and liquid dirt, which will cause pollution and burden to the main motor 14. The filter device 133 can preferably be a HEPA filter element, thereby improving the filtration effect.

[0040] The base station 2 disclosed herein is used to dock the cleaning equipment 1. Specifically, the base station 2 is used to place the cleaning equipment 1 and to perform maintenance on the cleaning equipment 1 docked thereon. For example, after the cleaning equipment 1 has finished cleaning the work surface, the user can dock it on the base station 2. This not only ensures that the cleaning equipment 1 is placed stably, but also allows the base station 2 to perform self-cleaning, charging, sewage discharge, and replenishment of cleaning fluid on the cleaning equipment 1 docked thereon, so that the user can use it next time.

[0041] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 2 The cleaning base station 2 includes a tray 22 extending horizontally and a base 23 extending vertically. The tray 22 supports the floor brush assembly 11, and the base 23 supports the body 12. Figure 2 As shown, a sewage trough 21 is provided in the base 23 of base station 2. The sewage trough 21 is configured to connect with the sewage outlet 131 at the bottom of the sewage tank 13 to discharge the dirt collected by the cleaning equipment 1. When the cleaning equipment 1 is in place, the sewage trough 21 connects with the sewage outlet 131, allowing the dirt in the sewage tank 13 to flow into the sewage trough 21 and be discharged into the sewer through the sewage trough 21. It should be noted that the sewage trough 21 can be a regular sewage pipe or a sewage chamber with a considerable volume, which can serve as a temporary storage function when sewage discharge is not smooth.

[0042] refer to Figure 2 , Figure 7 and Figure 8 The cleaning equipment also includes an air duct assembly 15, which can be installed on the body 12. The air duct assembly 15 has an air duct inlet 151 and an air duct outlet 152. The air duct inlet 151 is connected to the air outlet of the main motor 14, so that the main motor 14 blows air into the air duct assembly 15 while sucking the sewage tank to negative pressure, thereby forming an airflow from the air duct inlet 151 to the air duct outlet 152 in the air duct assembly 15.

[0043] refer to Figure 2 and Figure 3With the cleaning equipment 1 docked at the base station 2, the air duct outlet 152 is configured to connect to the sewage tank 21, and the airflow from the outlet is configured to be blown into the sewage tank 21 through the air duct assembly 15. It is understood that the main motor 14 will naturally generate heat during operation, therefore the airflow it blows out is hot air. The hot air is blown into the sewage tank 21 through the air duct assembly 15, thereby drying and sterilizing the sewage tank 21.

[0044] Specifically, when the main motor 14 is operating, the airflow from the suction port 113 is configured to sequentially pass through the suction channel 17, the sewage tank 13, the main motor 14, and the air duct assembly 15 before being blown into the sewage discharge tank 21. During operation, the main motor 14 can simultaneously perform two functions: self-cleaning suction and drying of the sewage discharge tank 21. The cleaning device 1 can perform self-cleaning on the base station 2, and the sewage generated during self-cleaning can be sucked into the sewage tank 13 through the suction port 113. At the same time as the sewage is sucked in, airflow will inevitably be sucked into the sewage tank 13. Therefore, this airflow can be used to blow the sewage into the sewage discharge tank 21 through the air duct assembly 15 for drying, thereby improving the airflow utilization rate of the main motor 14.

[0045] This disclosure, by setting up an air duct assembly 15, allows the air outlet of the main motor 14 to be connected to the sewage tank 21, thereby enabling drying and sterilization of the sewage tank 21. This disclosure eliminates the need for an additional drying mechanism on the base station 2; instead, it utilizes the existing main motor 14 on the cleaning device 1, providing a novel drying air path by adding the air duct assembly 15, thus improving the airflow utilization rate of the main motor 14. Compared to the solution of adding an additional drying mechanism to the base station 2, this disclosure offers lower drying costs, lower system complexity, easier maintenance of the newly added air duct assembly 15, and better sterilization effect on the sewage tank 21.

[0046] In one embodiment of this disclosure, reference is made to Figure 5 and Figure 6 The ventilation duct outlet 152 is located near the sewage outlet 131, such as Figure 2As shown, the top of the sewage trough 21 has an interface 210. When the cleaning equipment 1 is docked at the base station 2, the interface 210 is configured to simultaneously cover the sewage outlet 131 and the air duct outlet 152. The air duct outlet 152 is used to blow air into the sewage trough 21, and the sewage outlet 131 is used to discharge dirt into the sewage trough 21. Therefore, the air duct outlet 152 and the sewage outlet 131 need to be arranged adjacent to each other to facilitate simultaneous docking with the interface 210 on the top of the sewage trough 21. During docking, the interface 210 can cover both the sewage outlet 131 and the air duct outlet 152. This prevents dirt discharged from the sewage outlet 131 from splashing outside the sewage trough 21, avoiding pollution, and also ensures that the hot air blown out of the air duct outlet 152 basically completely enters the sewage trough 21, improving the air utilization rate.

[0047] In one embodiment of this disclosure, reference is made to Figures 6 to 8 The air duct assembly 15 includes a main air duct 153 and a side air duct 154 that are connected. The main air duct 153 is configured to extend downward from the position where it is connected to the main motor 14, and the side air duct 154 is configured to extend rearward from the lower end of the main air duct 153 to a position adjacent to the drain outlet 131 and form an air duct outlet 152. Further, two side air ducts 154 are provided, and two corresponding air duct outlets 152 are provided; the two side air ducts 154 are provided on both sides of the body 12 and are configured to extend rearward so that the two air duct outlets 152 are respectively located on both sides of the drain outlet 131. It should be noted that in other embodiments of this disclosure, there may be only one side air duct 154, or there may be three, four or more side air ducts 154. In the embodiment where two side air ducts 154 are provided, the two side air ducts 154 may also be asymmetrically arranged according to the actual spatial layout of the cleaning equipment 1. This embodiment only takes the example of setting two symmetrical side air ducts 154 for specific description. This disclosure does not make specific limitations on the number of side air ducts 154 or their layout.

[0048] Figures 6 to 8 The duct assembly 15 shown is an air duct formed by an enclosed air duct housing. In other embodiments of this disclosure, the duct assembly 15 may not include an air duct housing, but may be formed by other existing components on the cleaning device 1. It is understood that any structure that serves to guide air from the air outlet of the main motor 14 to the drain tank 21 can be considered as the duct assembly 15. The duct assembly 15 referred to in this disclosure is not limited to the independent component with a housing shown in the figures.

[0049] Specifically, the upper port of the main air duct 153 is configured as an air duct inlet 151 for connecting with the air outlet of the main motor 14. The main air duct 153 can be located at the front of the body 12 because a wastewater tank 13 is located at the rear of the body 12. If the main air duct 153 is located at the rear, it will conflict with the spatial layout of the wastewater tank 13 and may also result in too much structure at the rear of the body 12, making the center of gravity of the cleaning equipment 1 unstable. The main air duct 153 extends along the axial direction of the body 12, that is, from top to bottom, thereby guiding the airflow from the air outlet of the main motor 14 located above downwards.

[0050] Two side air ducts 154 are symmetrically connected to the lower end of the main air duct 153 and extend from front to back to a position adjacent to the drain outlet 131. The ends of the side air ducts 154 are configured as air duct outlets 152. The side air ducts 154 are used to guide the airflow from the main air duct 153 on the front side of the body 12 to the position adjacent to the drain outlet 131, thereby blowing air onto the drain tank 21. The two side air ducts 154 are symmetrically arranged, thereby making the airflow from the two air duct outlets 152 uniform and ensuring the stability of the cleaning equipment 1 during the airflow process. The main air duct 153 can be integrally formed with the side air ducts 154, thereby forming a top-to-bottom and front-to-back airflow within the body 12, so that the airflow from the air outlet of the main motor 14 can be blown towards the drain tank 21.

[0051] In one embodiment of this disclosure, reference is made to Figures 4 to 6 The main body 12 includes a base 121 configured to support the wastewater tank 13, with the air duct outlet 152 exposed on the bottom surface of the base 121. Specifically, in addition to supporting the wastewater tank 13, the base 121 also has a decorative function, at least covering the side air duct 154, thus preventing the outer wall of the side air duct 154 from being directly exposed and improving the aesthetics of the cleaning equipment 1. Figure 5 As shown, a docking groove 122 is provided on the base 121 at the front side of the air duct outlet 152. When the cleaning device 1 is docked at the base station 2, the interface 210 is configured to partially embed into the docking groove 122 and cover the drain outlet 131 and the air duct outlet 152 to the rear. Specifically, the docking groove 122 is located at the front side of the drain outlet 131 and the air duct outlet 152. When the cleaning device 1 is docked at the base station 2, the front edge of the interface 210 can be embedded in the docking groove 122, thereby improving the accuracy of docking. The size of the interface 210 is sufficient to cover the area on the base 121 behind the docking groove 122, that is, it can cover both the drain outlet 131 and the air duct outlet 152 at the same time.

[0052] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 5The bottom of the sewage tank 13 is provided with a drain cover 132, which is configured to move between an open position and a closed position to open and close the drain outlet 131. When the drain cover 132 moves to the open position, the drain outlet 131 is open, allowing the sewage in the sewage tank 13 to be discharged into the drain trough 21; when the drain cover 132 moves to the closed position, the drain outlet 131 is closed, and the sewage tank 13 is not connected to the drain trough 21. As airflow from the vent is blown into the drain trough 21 through the air outlet 152, the drain cover 132 is configured to remain in the closed position. As mentioned earlier, the inlet of the main motor 14 is connected to the sewage tank 13. If the drain cover 132 is opened during the blowing of air into the sewage trough 21, the sewage tank 13 will leak air from its drain port 131 while being drawn in by the main motor 14. This results in insufficient airflow into the air duct assembly 15 from the air outlet of the main motor 14, leading to a low airflow velocity from the air duct outlet 152 into the sewage trough 21, which fails to achieve a good drying effect. Therefore, the drain cover 132 needs to be closed when the main motor 14 is working. This creates a strong negative pressure in the sewage tank 13, ensuring the airflow and velocity, so that the airflow blown into the sewage trough 21 through the air duct outlet 152 can achieve a good drying and sterilization effect.

[0053] In one embodiment of this disclosure, such as Figure 2 As shown, a filter screen 211 is installed in the sewage tank 21. When the cleaning equipment 1 is docked at the base station 2, and the sewage cover 132 moves to the open position, the dirt in the sewage tank 13 is directed to flow to the filter screen 211. It is understood that the dirt from the sewage tank 13 of the cleaning equipment 1 contains not only liquids such as sewage, but also solid waste such as hair, paper scraps, and debris. During subsequent discharge into the sewer system, this solid waste can easily cause blockages. Therefore, in this embodiment, a filter screen 211 is installed in the sewage tank 21 to filter the dirt entering the sewage tank 21. Solid waste can be filtered out by the filter screen 211, thereby avoiding blockages caused by subsequent discharge.

[0054] Solid waste filtered by filter 211 tends to accumulate on it, which can easily produce odors. To address this issue, the airflow from duct outlet 152 is configured to pass through filter 211 and be blown into drain trough 21. The waste on filter 211 can be dried by the airflow from duct outlet 152, thereby reducing odor generation. Solid waste can remain on filter 211 for a longer period, thus reducing the frequency of cleaning filter 211 and improving the user experience.

[0055] In one embodiment of this disclosure, reference is made to Figure 2 , Figures 9 to 12The main body 12 is provided with a mounting base 161, and the main motor 14 is configured to be installed in the mounting base 161. The mounting base 161 and the bottom of the main motor 14 are configured to form a transfer air duct 162. The air outlet of the main motor 14 is configured to be connected to the air duct inlet 151 through the transfer air duct 162. Furthermore, the main body 12 is provided with an air intake duct 163 connecting the sewage tank 13 and the main motor 14. The air intake duct 163 is configured to extend into the mounting base 161 and be connected to the air intake of the main motor 14. Part of the outer wall of the air intake duct 163 and the inner wall of the mounting base 161 together form an annular transfer air duct 162.

[0056] The air inlet of the main motor 14 is located in its central position, and the air outlet is located on its outer periphery. For example... Figure 12 As shown, the air intake duct 163 includes a first opening 1631 for communicating with the sewage tank 13 and a second opening 1632 for communicating with the air intake of the main motor 14. The main motor 14 can draw gas from the sewage tank 13 through the air intake duct 163. The gas drawn into the main motor 14 can be discharged from the air outlet on its outer peripheral surface and flow into the annular transfer duct 162. The transfer duct 162 is formed at least by a portion of the outer wall of the air intake duct 163 and the inner wall of the mounting base 161, and the main motor 14, located on the mounting base 161, can form an annular airflow within the transfer duct 162. Figure 9 As shown, a transfer air outlet 1621 for connecting with the air inlet 151 is provided on the bottom surface of the transfer air duct 162. Since the air inlet 151 is the upper port of the main air duct 153 and the main air duct 153 is located on the front side of the body 12, the transfer air outlet 1621 can be opened on the front side of the bottom surface of the transfer air duct 162.

[0057] This disclosure provides a structural foundation for installing the main motor 14 by setting up a mounting base 161, a transfer duct 162, and an air intake duct 163. On the other hand, it realizes the air passage connecting the sewage tank 13, the main motor 14, and the air duct assembly 15. During the operation of the main motor 14, the airflow from the sewage tank 13 flows through the air intake duct 163 to the air inlet of the main motor 14, and is discharged from the air outlet of the main motor 14 into the annular transfer duct 162. Then, it flows downward into the air duct assembly 15 through the transfer air outlet 1621. Under the guidance of the air duct assembly 15, it is blown towards the sewage tank 21, which plays a role in drying and sterilization.

[0058] In one embodiment of this disclosure, reference is made to Figure 2The tray 22 is equipped with a drying air duct 223 that communicates with the outside. When the cleaning equipment 1 is docked at the base station 2, the outlet of the drying air duct 223 is configured to face the suction port 113. Specifically, the inlet of the drying air duct 223 is a cold air inlet 221 that communicates with the outside, and the outlet of the drying air duct 223 is a hot air outlet 222 that communicates with the outside. The drying air duct 223 is equipped with a blower motor 225 and a heating element 224, wherein the heating element 224 can be a PTC heater. When the blower motor 225 is working, outside air can enter the drying air duct 223 through the cold air inlet 221. The cold air is heated into hot air by the heating element 224 in the drying air duct 223 and blown out of the tray 22 from the hot air outlet 222.

[0059] With the cleaning device 1 docked at the base station 2, the hot air outlet 222 faces the suction port 113, allowing the suction port 113 to directly draw in high-velocity hot air. When the blower motor 225 and the main motor 14 are operating simultaneously, the airflow from the inlet of the drying duct 223 is configured to sequentially pass through the drying duct 223, the suction port 113, the suction channel 17, the wastewater tank 13, the main motor 14, and the duct assembly 15 before being blown into the drain tank 21. It is understandable that if outside air is directly drawn in through the suction port 113, and the airflow is only heated by the heat generated by the main motor 14, the drying effect of the hot air flow rate and temperature blown into the drain tank 21 is relatively limited. However, this embodiment can provide high-velocity hot air to the suction port 113 through the drying duct 223 within the tray 22, thus giving the hot air blown into the drain tank 21 a higher flow rate and temperature, significantly improving the drying and sterilization effect on the drain tank 21.

[0060] In one embodiment of this disclosure, reference is made to Figure 2 With the cleaning device 1 docked at the base station 2, the roller brush 112 is configured to be located on the air supply path from the outlet of the drying duct 223 to the suction port 113. Specifically, the roller brush 112 is wet after operation or self-cleaning and is prone to bacterial growth. Therefore, the hot air outlet 222 is positioned towards the roller brush 112, so that the hot air blown from the hot air outlet 222 passes through the roller brush 112 before entering the suction port 113, thereby drying and sterilizing the roller brush 112. In this way, the utilization rate of the hot air from the drying duct 223 is improved, and the roller brush 112 is dried while the drain tank 21 is being dried, thus preventing bacterial growth and odor on the roller brush 112 and improving the user experience.

[0061] In one embodiment of this disclosure, reference is made to Figure 3A sewage pipe 232 is provided on the base 23, connecting the sewage trough 21 to the drain outlet. The sewage pipe 232 is constructed for discharging sewage and waste gas. It is understood that in conventional solutions, the sewage pipe 232 is only used for discharging sewage. However, since this disclosure includes a path for blowing air into the sewage trough 21 for drying, the sewage pipe 232 also needs to discharge waste gas from the sewage trough 21. The waste gas should not be discharged into the sewer pipe along with the sewage, but rather needs to be discharged into the atmosphere. Specifically, a drain tee 233 is provided at the end of the sewage pipe 232. The drain tee 233 includes an inlet 2331 for connecting to the sewage pipe 232, a lower outlet 2332 for connecting to the drain outlet, and an upper outlet 2333 for connecting to the atmosphere. A purification device 231 is provided at the upper outlet 2333 to purify the waste gas discharged from the upper outlet 2333. The gas-liquid mixture entering the sewage pipe 232 through the inlet 2331 of the drain tee 233 will naturally separate under gravity. Wastewater will be discharged into the sewer through the lower outlet 2332, while waste gas will be discharged into the atmosphere through the upper outlet 2333. A purification device 231 installed at the upper outlet 2333 can filter the discharged waste gas, thereby removing odors and improving the user experience. Preferably, the purification device 231 can use a HEPA filter element to improve the filtration effect.

[0062] Application scenarios

[0063] In a home cleaning scenario, cleaning device 1 can be a handheld floor scrubber. The user holds the handheld part 10, tilts the body 12, and pushes and pulls it back and forth. The floor brush assembly 11 moves accordingly on the work surface to clean the dirt. After the handheld floor scrubber has finished cleaning the work surface, the user can park it on the cleaning base station 2. This not only ensures the handheld floor scrubber is placed stably, but also allows the cleaning base station 2 to perform self-cleaning, charging, waste discharge, and cleaning fluid replenishment on the handheld floor scrubber parked on it, so that it can be used by the user next time.

[0064] An interface 210 is provided on the top of the sewage tank 21 of base station 2. When the handheld floor scrubber is docked at base station 2, the interface 210 is configured to simultaneously cover the sewage outlet 131 and the air duct outlet 152. After the machine is docked stably, the sewage cover 132 can be opened to open the sewage outlet 131 and pour the dirt collected by the handheld floor scrubber during operation into the sewage tank 21. After the dirt is filtered by the filter screen 211, liquid dirt can be directly discharged through the sewage pipe 232, while solid waste will remain on the filter screen 211.

[0065] After the waste is emptied, the drain cover 132 is closed. Then, the main motor 14 and the blower motor 225 can be started simultaneously. External air can enter the drying duct 223 through the cold air inlet 221. The cold air is heated into hot air by the heating element 224 in the drying duct 223 and blown out of the tray 22 from the hot air outlet 222. The hot air blown out of the hot air outlet 222 passes through the roller brush 112 before entering the suction port 113, thereby drying and sterilizing the roller brush 112.

[0066] The suction port 113 can directly draw in high-velocity hot air, which then passes through the suction channel 17, the wastewater tank 13, and the main motor 14 before entering the air duct assembly 15. The hot air flows downwards along the main air duct 153 within the air duct assembly 15, and then flows rearwards along the side air duct 154 to a position adjacent to the discharge port 131, finally being blown out from the air duct outlet 152. The hot air can blow onto the filter screen 211, drying the debris on the filter screen 211 with the airflow from the air duct outlet 152, thereby reducing odor generation. The gas in the discharge tank 21 can flow through the discharge pipe 232 to the drain tee 233, and then be discharged to the atmosphere through its upper outlet 2333. The purification device 231 installed at the upper outlet 2333 can filter the discharged exhaust gas, thereby removing odors and improving the user experience.
