Description

Technical Field

[0001] This utility model relates to the field of cleaning system technology, and in particular to a recycling bin, cleaning equipment and cleaning system. Background Technology

[0002] In existing carpet cleaning machine technologies, a motor-driven suction device is typically used to generate negative pressure, drawing wastewater and impurities generated during the cleaning process into a collection tank. However, in actual use, hair, fibers, dust, and other impurities on the carpet can easily enter the suction device with the airflow, and may even further penetrate the motor cavity, leading to problems such as blocked suction channels, poor motor heat dissipation, and rotor jamming, thereby affecting the overall lifespan and operational stability of the machine.

[0003] To address this, some existing carpet cleaning machines incorporate filters or baffles in their airflow channels to intercept impurities and prevent them from entering critical components. However, existing filters suffer from insufficient filtration accuracy if the filter holes are too large, allowing hair, fibers, dust, and other impurities from the carpet to easily enter the suction unit with the airflow; conversely, if the filter holes are too small, the filter structure is prone to clogging. Therefore, a well-designed filtration and protection solution that is easy to observe and clean is urgently needed to improve the reliability and practicality of carpet cleaning machines. Utility Model Content

[0004] The main purpose of this invention is to propose a recycling bin, cleaning equipment, and cleaning system, which aims to solve the problem that the accumulation of impurities in the filter structure of the airflow channel of existing cleaning equipment cannot be observed by users in a timely and convenient manner.

[0005] To achieve the above objectives, the present invention proposes a recycling bin for use in cleaning equipment. The recycling bin has an air inlet, an air outlet, and an airflow channel connecting the air inlet and the air outlet. The recycling bin includes:

[0006] The housing has an inner cavity with an opening at the upper end and an air inlet communicating with the inner cavity;

[0007] A cover, detachably fitted onto the opening of the box; and,

[0008] A filter structure is disposed within the airflow channel, the filter structure comprising a first filter structure and a second filter structure arranged sequentially at intervals along the airflow direction from the air inlet to the air outlet;

[0009] The airflow channel includes a first channel formed on the housing, the first channel connecting the air outlet and the inner cavity, and the second filter structure installed between the first channel and the cover.

[0010] Optionally, the airflow channel is at least partially formed on the cover to form a second channel on the cover, and the first filter structure is mounted on the second channel.

[0011] Optionally, the air inlet and air outlet of the second channel are located at the bottom of the cover.

[0012] The air inlet of the second channel is connected to the inner cavity, the air outlet of the second channel is connected to the air inlet of the first channel, and the first filter structure is installed at the air inlet of the second channel.

[0013] Optionally, in the vertical direction, the first filter structure is positioned above the second filter structure, such that airflow passes through the first filter structure from bottom to top and then through the second filter structure from top to bottom.

[0014] Optionally, the first filter structure is provided with a retaining part, and the cover is provided with a mating part that engages with the retaining part.

[0015] Optionally, the second filter structure is detachably installed at the air inlet port of the first channel;

[0016] The second filter structure includes a main body and an overlapping part. The main body is disposed corresponding to the first channel and has a plurality of filter holes. The overlapping part overlaps with the inner peripheral flange of the air inlet port of the first channel.

[0017] Optionally, the main body is recessed towards the inside of the first channel to form a placement groove with the opening facing outward of the first channel, the placement groove being used to place the filter element.

[0018] Optionally, the recycling bin further includes a sealing ring disposed between the air inlet port of the first channel and the air outlet port of the second channel to seal the air inlet port of the first channel and the air outlet port of the second channel.

[0019] Optionally, the sealing ring engages with the outer periphery of the air inlet port of the first channel and abuts against the overlapping portion, so as to press the overlapping portion against the inner peripheral flange of the air inlet port of the first channel.

[0020] The utility model also proposes a cleaning device, which includes:

[0021] The aforementioned recycling bins;

[0022] A base, on which a suction channel and an air inlet channel are provided, wherein the air outlet of the suction channel is connected to the air inlet, and the air inlet port of the air inlet channel is connected to the air outlet; and,

[0023] An electric motor is located within the air intake passage.

[0024] Optionally, the recycling bin is detachably installed on the top of the base, and the air outlet of the suction channel and the air inlet of the air inlet channel are both located on the top of the housing. When the recycling bin is installed on the base, the air outlet of the suction channel is connected to the air inlet, and the air inlet of the air inlet channel is connected to the air outlet.

[0025] The utility model also proposes a cleaning device, which includes:

[0026] The aforementioned cleaning equipment; and,

[0027] A tray for holding the cleaning equipment.

[0028] The technical solution provided by this utility model has at least the following advantages:

[0029] The system employs a first filter structure and a second filter structure arranged sequentially along the airflow direction. The first filter structure, located near the air inlet, intercepts large particles such as hair and fibers. The second filter structure, installed at the air inlet of the first channel, further filters fine dust, achieving dual filtration and improving filtration efficiency. Because the second filter structure is located in the middle to rear section of the airflow channel, in a more stable airflow area, its impurity accumulation more accurately reflects the unobstructed state of the airflow channel. When the cover is open, the user can directly observe its cleanliness, facilitating timely cleaning without disassembling other components, thus improving maintenance convenience.

[0044] Most existing carpet cleaning machines use a motor-driven suction device to generate negative pressure, sucking in wastewater and impurities generated during the cleaning process. However, hair, fibers, and dust can easily enter the suction device and even the motor cavity with the airflow, causing blockages, poor heat dissipation, and rotor jamming, affecting the equipment's lifespan and stability. While some cleaning machines incorporate filters or baffles in the airflow channel to remove impurities, these structures suffer from drawbacks: if the filter holes are too large, the precision is insufficient, allowing impurities to easily enter the fan; if they are too small, blockages are likely. Therefore, there is an urgent need for a well-designed filtration and protection solution that is easy to observe and clean, to improve the reliability and practicality of carpet cleaning machines.

[0045] This utility model provides a wastewater collection bin 100 and a cleaning device 200. The collection bin 100 is suitable for collecting wastewater and impurities generated during the cleaning process. The collection bin 100 can be applied to household and commercial cleaning equipment such as carpet cleaners, vacuum cleaners, floor scrubbers, robotic vacuum cleaners, steam cleaners, and multi-functional cleaning devices. For ease of explanation, the specific structure of the wastewater collection bin 100 will be described below using the application of the wastewater collection bin 100 in the cleaning device 200 as an example. Other devices can be adapted accordingly.

[0046] Please see Figure 1 and Figure 9 In one embodiment of this utility model, the cleaning device 200 includes a recycling bin 100, a base 10, and a motor 20. The recycling bin 100 has an air inlet a, an air outlet b, and an airflow channel connecting the air inlet a and the air outlet b. The base 10 is provided with a suction channel 10a and an air inlet channel 10b. The air outlet of the suction channel 10a is connected to the air inlet a, and the air inlet of the air inlet channel 10b is connected to the air outlet b. The motor 20 is installed on the base 10 and is located inside the air inlet channel 10b.

[0047] Understandably, the suction channel 10a is used to suck impurities or wastewater from the floor cleaning area into the cleaning equipment 200. Its air outlet is connected to the air inlet a of the recovery box 100 so that the sucked airflow and the impurities or wastewater it carries can be guided into the inner cavity 1b of the recovery box 100. The air inlet channel 10b is used to guide the airflow out from the air outlet b of the recovery box 100. Its air inlet port is connected to the air outlet b, thus forming a complete airflow circulation path.

[0048] The motor 20 is mounted on the base 10 and located inside the air intake channel 10b. The motor 20 drives the suction device, generating negative pressure to force airflow into the suction channel 10a, which then passes sequentially through the filter structures 3 and 4 of the recovery box 100, and finally exits through the air intake channel 10b. Because the motor 20 is located in the air intake channel 10b, it is at the end of the airflow path.

[0049] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the recycling bin 100 has an air inlet a, an air outlet b, and an airflow channel connecting the air inlet a and the air outlet b. The recycling bin 100 includes a body 1, a cover 2, and a filter structure. The body 1 has an inner cavity 1b with an opening 1a at the upper end and an air inlet a connected to the inner cavity 1b. The cover 2 is detachably installed on the opening 1a end of the body 1. The filter structure is located in the airflow channel and includes a first filter structure 3 and a second filter structure 4 arranged sequentially at intervals in the airflow direction from the air inlet a to the air outlet b. The airflow channel includes a first channel 1c formed on the body 1, which connects the air outlet b and the inner cavity 1b. The second filter structure 4 is installed between the first channel 1c and the cover 2.

[0050] Understandably, the housing 1 has an inner cavity 1b, the upper end of which has an opening 1a for engaging with the cover 2. The housing 1 has an air inlet a and an air outlet b, which are connected by an airflow channel. Specifically, the airflow channel includes a first channel 1c formed on the housing 1, one end of which communicates with the air outlet b, and the other end extends into the inner cavity 1b.

[0051] Please see Figures 2 to 4 The cover 2 is detachably installed on the opening 1a end of the housing 1 to close or open the inner cavity 1b. During the operation of the cleaning equipment 200, the airflow enters the recovery box 100 from the air inlet a, passes through the filter structure in sequence, and is finally discharged through the air outlet b.

[0052] The filter structure is set in the airflow channel and includes a first filter structure 3 and a second filter structure 4. The first filter structure 3 is located near the air inlet a and is used to intercept larger particles of impurities, such as hair and fibers. The second filter structure 4 is installed at the air inlet of the first channel 1c and is used to further intercept fine dust and other impurities, thus achieving dual filtration.

[0053] Specifically, the first filter structure 3 is located near the air inlet a of the equipment. Its filter pores are relatively large, mainly used to intercept large particulate impurities such as hair and fibers, playing a primary filtration role. While ensuring high flow capacity, it effectively prevents large particles from entering downstream components, avoiding mechanical damage to the fan or ductwork.

[0054] The second filter structure 4 is located downstream of the first filter structure 3. Its filter holes are smaller and are used to perform fine filtration on the airflow after primary filtration, further intercepting fine particles such as dust, improving the overall filtration accuracy, and preventing micro-dust from entering the air suction device and causing pollution or performance degradation.

[0055] By setting the filtration function in stages, this embodiment achieves the step-by-step interception of large and small particles: the first filter structure 3 focuses on flow prevention and anti-clogging, while the second filter structure 4 focuses on precision filtration. While ensuring high filtration efficiency, it reduces the risk of clogging or filtration failure caused by improper selection of pore size in a single filter structure, thus balancing the contradiction between filtration performance and system stability.

[0056] Preferably, the air inlet of the first channel 1c is oriented toward the opening 1a. When the cover 2 is opened, the user can directly observe the second filter structure 4 located at that position and the accumulation of impurities on its surface, and determine whether it is blocked by impurities or has serious dust accumulation, thereby deciding whether it needs to be cleaned. The user can check and clean the filter structure without disassembling other parts of the recycling box 100.

[0057] It should be noted that, compared to the first filter structure 3, the second filter structure 4 is located closer to the middle and rear section of the airflow channel, in an area where the airflow velocity is relatively stable and the distribution is more uniform. Therefore, the accumulation of impurities on its surface can more accurately reflect the overall unobstructedness of the airflow channel. The first filter structure 3, being closer to the air inlet a, primarily intercepts large particles, which can easily lead to localized accumulation while the overall airflow remains unobstructed. Users may not be able to accurately determine whether the system is at risk of blockage simply by observing the first filter structure 3. Therefore, placing the second filter structure 4 in a location easily observable by the user enhances their awareness of the equipment's operating status, facilitating timely maintenance.

[0058] It should be noted that the working process of the recycling bin 100 in the cleaning equipment 200 is as follows:

[0059] When the ground is dry, the suction device of the cleaning equipment 200 is connected to the air outlet of the airflow channel through the air inlet channel 10b, driving the airflow so that impurities can be sucked in from the suction channel 10a of the base 10 and enter the inner cavity 1b of the recycling box 100 through the air inlet a. Larger impurities are deposited at the bottom of the inner cavity 1b of the box 1 under the deceleration effect of the airflow, while smaller impurities and hair are intercepted by the first filter structure 3 and the second filter structure 4 in sequence to prevent them from entering the motor 20, thereby protecting the motor 20 from the influence of impurities.

[0060] When there is sewage on the ground, the sewage enters the inner cavity 1b of the recycling box 100 through the suction channel 10a of the base 10 and the air inlet a. Under the action of gravity, the sewage settles at the bottom of the box 1. Small impurities and hairs carried in the sewage are also intercepted by the first filter structure 3 and the second filter structure 4 in sequence, preventing them from entering the side of the air intake channel 10b where the motor 20 is located, thereby ensuring the safe operation of the motor 20 and improving the stability and service life of the cleaning equipment 200.

[0061] The system employs a first filter structure 3 and a second filter structure 4 arranged sequentially along the airflow direction. The first filter structure 3, located near the air inlet a, intercepts large particles such as hair and fibers. The second filter structure 4, installed at the air inlet of the first channel 1c, further filters fine dust, achieving dual filtration and improving filtration efficiency. Since the second filter structure 4 is located in the middle to rear section of the airflow channel, in a more stable airflow area, its impurity accumulation more accurately reflects the unobstructed state of the airflow channel. Furthermore, its position faces the opening 1a, allowing users to directly observe its cleanliness when the cover 2 is open, facilitating timely cleaning without disassembling other components and enhancing maintenance convenience.

[0062] Specifically, please refer to Figures 5 to 8 In this embodiment, the airflow channel is at least partially formed on the cover 2 so that a second channel 2a is formed on the cover 2, and the first filter structure 3 is installed on the second channel.

[0063] It is understandable that the second channel 2a, as part of the airflow channel, is formed inside or on the surface of the cover 2 and is connected to the first channel 1c on the box 1, thereby constructing a complete airflow path.

[0064] When the cover 2 and the housing 1 are assembled, the second channel 2a on the cover 2 connects with the first channel 1c on the housing 1, forming a complete airflow path. The airflow passes sequentially through the air inlet a, the first filter structure 3 in the second channel 2a, the inner cavity 1b, and the second filter structure 4 in the first channel 1c, finally exiting through the air outlet b. At this time, the air inlet of the first channel 1c faces the opening 1a, exposing the second filter structure 4 to one side of the opening 1a, allowing the user to directly observe the accumulation of impurities on its surface when opening the cover 2.

[0065] When the cover 2 is removed, the airflow channel is disconnected, and the second channel 2a is separated from the overall airflow path. At this time, the air inlet port of the first channel 1c is fully exposed, which further facilitates the user's inspection and cleaning of the second filter structure 4.

[0066] Understandably, if all airflow channels are located on the housing 1, both the first filter structure 3 and the second filter structure 4 would be inside the housing 1, making it difficult for the user to observe and clean the second filter structure 4. Furthermore, if the air inlet of the first channel 1c is entirely inside the housing 1, it would be difficult to position it facing the opening 1a, hindering the user from directly observing the state of the second filter structure 4 when opening the cover 2.

[0067] By incorporating part of the airflow channel into the cover 2, not only is the integrity and functionality of the airflow channel achieved, but the detachable nature of the cover 2 also allows for a complete airflow path during installation and disconnection of the airflow channel during disassembly, exposing the air inlet of the first channel 1c and the second filter structure 4. This ensures that the second filter structure 4 is always easily observable by the user. Therefore, placing part of the airflow channel on the cover 2 not only optimizes the overall airflow path layout but also makes the installation positions of the first filter structure 3 and the second filter structure 4 more reasonable, improving the functionality and maintainability of the recycling bin 100.

[0068] Further, please refer to Figures 6 to 8 In this embodiment, the air inlet and air outlet of the second channel 2a are located at the bottom of the cover 2; the air inlet of the second channel 2a is connected to the inner cavity 1b, the air outlet of the second channel 2a is connected to the air inlet of the first channel 1c, and the first filter structure 3 is installed at the air inlet of the second channel 2a.

[0069] The first filter structure 3 is installed at the air inlet port of the second channel 2a, that is, at the air inlet at the bottom of the cover 2, and is used to intercept large particulate impurities in the airflow entering the second channel 2a from the inner cavity 1b.

[0070] When the cover 2 is removed, the second channel 2a separates from the box 1 along with the cover 2. At this time, the first filter structure 3 is located on the outside of the bottom of the cover 2, within the user's field of vision, making it easy for the user to directly observe the accumulation of impurities on its surface.

[0071] Since the first filter structure 3 is installed at the air inlet of the second channel 2a, impurities are first impacted and accumulated on the outside of the first filter structure 3 by the airflow. Therefore, they will not enter the interior of the second channel 2a or other structures, thus avoiding the difficulty of cleaning impurities inside the cover 2. It also avoids the inconvenience of observation and cleaning caused by placing the first filter structure 3 inside the box 1.

[0072] Further, please refer to Figure 5 In the vertical direction, the first filter structure 3 is positioned above the second filter structure 4, so that the airflow passes through the first filter structure 3 from bottom to top, and then passes through the second filter structure 4 from top to bottom.

[0073] Specifically, the first filter structure 3 is installed at the air inlet port of the second channel 2a at the bottom of the cover 2, while the second filter structure 4 is installed at the air inlet port of the first channel 1c on the housing 1. When the cover 2 is closed on the opening 1a of the housing 1, the two filter structures 3 and 4 are arranged vertically in a staggered manner. The airflow enters from the bottom of the inner cavity 1b, first passing through the first filter structure 3 from bottom to top, then the airflow direction changes, flowing from top to bottom through the second filter structure 4, entering the first channel 1c, and finally being discharged through the air outlet b.

[0074] In this airflow path, the first filter structure 3 is mainly used to intercept larger particulate impurities such as hair and fibers. Since its orientation is from bottom to top, the larger particles carried by the airflow, after passing through the first filter structure 3, lose airflow support and can fall directly to the bottom of the inner cavity 1b of the housing 1 under the action of gravity, thus avoiding them from adhering to the surface of the first filter structure 3 and causing blockage.

[0075] In addition, after passing through the first filter structure 3, the airflow changes direction and flows from top to bottom through the second filter structure 4, which changes the direction of the airflow and facilitates the settling and interception of fine particles in the airflow, thereby improving the filtration efficiency of the second filter structure 4.

[0076] Furthermore, to ensure that the first filter structure 3 does not detach due to its own weight or vibration during equipment operation, please refer to [link / reference needed]. Figure 3 In this embodiment, the first filter structure 3 is provided with a retaining part 31, and the cover 2 is provided with a mating part 21 that engages with the retaining part 31.

[0077] When the first filter structure 3 is assembled onto the cover 2, the holding part 31 and the mating part 21 are aligned and a certain pressure is applied, and the two are locked together and fixed, so that the first filter structure 3 is stably maintained at the air inlet port position of the second channel 2a.

[0078] The snap-fit ​​structure between the retaining part 31 and the mating part 21 can be implemented in various forms. For example, in one embodiment, the retaining part 31 is an elastic buckle provided on the edge of the first filter structure 3, and the mating part 21 is a corresponding snap hole on the cover 2. The elastic buckle is inserted into the snap hole to achieve fixation. In another embodiment, the retaining part 31 is a hook-shaped structure, and the mating part 21 is a limiting protrusion on the cover 2. The two are connected by sliding snap-fit. In yet another embodiment, the retaining part 31 is a magnetic component, and the mating part 21 is a metal sheet embedded in the cover 2. The first filter structure 3 is stably installed through magnetic attraction.

[0079] Thus, the snap-fit ​​between the holding part 31 and the mating part 21 not only enhances the installation reliability of the first filter structure 3, but also prevents airflow leakage or filter failure caused by structural loosening.

[0080] Further, please refer to Figure 6 In this embodiment, the second filter structure 4 is detachably installed at the air inlet port of the first channel 1c; the second filter structure 4 includes a main body 41 and an overlapping part 42. The main body 41 is provided corresponding to the first channel 1c, and a plurality of filter holes 41a are provided on the main body 41. The overlapping part 42 overlaps with the inner peripheral flange of the air inlet port of the first channel 1c.

[0081] Specifically, the second filter structure 4 is detachably installed at the air inlet port of the first channel 1c on the housing 1, so that the user can directly inspect and clean it when the cover 2 is opened. The second filter structure 4 includes a main body 41 and an overlapping part 42. The main body 41 is correspondingly provided with the first channel 1c and has a plurality of filter holes 41a for filtering fine impurities in the airflow, such as dust and lint. The overlapping part 42 is located at the periphery of the main body 41 and is used to form an overlapping fit with the inner peripheral flange at the air inlet port of the first channel 1c to achieve stable structural support and axial limit, so that the second filter structure 4 will not be displaced or fall off due to airflow impact or vibration during use.

[0082] Understandably, when the second filter structure 4 is installed onto the first channel 1c, the overlapping portion 42 extends radially outward and abuts against the inner circumferential flange of the air inlet port of the first channel 1c, thereby achieving stable support and positioning. This design allows for installation without additional fasteners and facilitates quick disassembly by the user through manual application of external force.

[0083] Further, please refer to Figure 6In this embodiment, the main body 41 is recessed towards the inside of the first channel 1c, forming a placement groove 41b with the opening facing the outside of the first channel 1c. The placement groove 41b is used to place the filter element (not shown in the figure).

[0084] Understandably, the main body 41 itself is provided with multiple filter holes 41a to achieve basic filtration function; at the same time, by providing placement grooves 41b in its center or periphery, the main body 41 can not only be used as a filter element itself, but also as a support structure to support other filter materials, thereby achieving a multi-stage filtration effect. After the filter element is placed in the placement groove 41b, it can be fixed by snap-fitting, bonding, or embedding to ensure that it will not fall off or shift under the action of airflow.

[0085] It should be noted that the filter element is made of replaceable or washable filter materials such as filter cotton or non-woven fabric.

[0086] By providing a recessed placement groove 41b on the main body 41 of the second filter structure 4, facing inward towards the first channel 1c, and installing filter elements (such as filter cotton) in the placement groove 41b, a multi-functional integrated design of the main body 41 is achieved. The main body 41 itself performs preliminary filtration of the airflow through the filter holes 41a, while the placement groove 41b it forms can also hold other filter materials, thereby improving the filtration accuracy and adaptability of the second filter structure 4 without adding additional structures.

[0087] It should be noted that since the airflow channel of the recycling bin 100 is partly located on the bin body 1 and partly located on the removable cover 2, manufacturing tolerances or deformation caused by material shrinkage or aging are inevitable during assembly. If it is not sealed, airflow leakage and wind pressure drop will occur, which will affect the overall suction and cleaning efficiency of the cleaning equipment 200.

[0088] Further, please refer to Figure 6 and Figure 7 In this embodiment, the recycling bin 100 also includes a sealing ring 6, which is disposed between the air inlet port of the first channel 1c and the air outlet port of the second channel 2a to seal the air inlet port of the first channel 1c and the air outlet port of the second channel 2a.

[0089] Specifically, the sealing ring 6 is sleeved or embedded on the outer periphery of the air inlet port of the first channel 1c or the inner periphery of the air outlet port of the second channel 2a. When the cover 2 and the box 1 are assembled in place, the sealing ring 6 is compressed and deformed, filling the assembly gap between the two and preventing airflow leakage from the connection. In this way, the stable operation of the recycling box 100 under different usage conditions, even with manufacturing tolerances or slight deformation of materials during use, can maintain good airtightness through the elastic compensation of the sealing ring 6.

[0090] Further, please refer to Figure 6 and Figure 7 In this embodiment, the second filter structure 4 includes a main body 41 corresponding to the first channel 1c and provided with a plurality of filter holes 41a, and an overlapping portion 42 that overlaps with the inner peripheral flange of the air inlet port of the first channel 1c; the sealing ring 6 engages with the outer peripheral edge of the air inlet port of the first channel 1c and abuts against the overlapping portion 42, so as to press the overlapping portion 42 against the inner peripheral flange of the air inlet port of the first channel 1c.

[0091] Understandably, the sealing ring 6 is not only positioned between the air inlet port of the first channel 1c and the air outlet port of the second channel 2a to achieve a sealed connection between them, but also forms a retaining engagement with the outer periphery of the air inlet port of the first channel 1c. When the cover 2 is assembled in place, the sealing ring 6, while being compressed and deformed, also abuts against the overlapping portion 42 of the second filter structure 4, and further presses the overlapping portion 42 against the inner peripheral flange of the air inlet port of the first channel 1c through its elastic restoring force, thereby achieving a sealing function while also playing an auxiliary role in fixing the second filter structure 4.

[0092] In this way, the second filter structure 4 can be stably installed without the need for additional fasteners, improving assembly efficiency and enhancing the stability of the second filter structure 4 under airflow impact or equipment vibration.

[0093] Further, please refer to Figure 9 In this embodiment, the recycling bin 100 is detachably installed on the top of the base 10. The air outlet of the suction channel 10a and the air inlet of the air inlet channel 10b are both located on the top of the housing. When the recycling bin 100 is installed on the base 10, the air outlet of the suction channel 10a is connected to the air inlet a, and the air inlet of the air inlet channel 10b is connected to the air outlet b.

[0094] Understandably, the recycling bin 100 is detachably mounted on top of the base 10, facilitating installation, removal, or cleaning by the user as needed. The base 10 is equipped with a suction channel 10a and an air intake channel 10b. The suction channel 10a is used to transport impurities and wastewater sucked in during the cleaning process to the recycling bin 100, and its air outlet is located at the top of the base 10. The air intake channel 10b is used to guide the airflow filtered by the recycling bin 100 into the area where the motor 20 is located, and its air intake port is also located at the top of the base 10.

[0095] When the recycling bin 100 is installed on top of the base 10, the air inlet a of the recycling bin 100 is connected to the air outlet of the suction channel 10a, and the air outlet b is connected to the air inlet of the air inlet channel 10b, thus forming a complete airflow path. The airflow enters the recycling bin 100 through the suction channel 10a, undergoes double filtration by the first filter structure 3 and the second filter structure 4, is discharged from the air outlet b, enters the motor 20 area through the air inlet channel 10b, and is finally discharged from the equipment exhaust port.

[0096] By detachably mounting the recycling bin 100 to the top of the base 10, and placing both the air outlet of the suction channel 10a and the air inlet of the air inlet channel 10b on the top of the base 10, quick docking and disassembly between the recycling bin 100 and the base 10 are achieved. Furthermore, this makes the airflow path more direct and smooth, reducing increased airflow resistance or leakage problems caused by structural misalignment or loose connections.

[0097] This utility model also proposes a cleaning device, which includes a cleaning device 200 and a tray, the tray being used to place the cleaning device 200.

[0098] Specifically, the tray is used to support and place the cleaning equipment 200, and can serve as a platform for parking, charging, or storing the cleaning equipment 200. In some embodiments, the tray may integrate a charging interface that contacts the electrodes on the bottom of the cleaning equipment 200 to enable automatic charging; it may also be provided with a drainage channel or water collection structure to facilitate the discharge of residual liquid after the cleaning equipment 200 completes wet cleaning operations, thereby improving hygiene and ease of use.

[0099] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
