Description

Technical Field

[0001] This utility model relates to the field of household appliances, specifically to a flow guide component. Based on this, it also relates to a water tank assembly including the flow guide component and a self-moving robot, as well as a base station used in conjunction with the self-moving robot, and a cleaning system comprising the self-moving robot and the base station. Background Technology

[0002] With the widespread adoption of smart home products, automated cleaning equipment, especially robotic vacuum cleaners, has become an integral part of modern family life. Robotic vacuum cleaners, with their autonomous navigation, cleaning path planning, and efficient cleaning functions, greatly simplify household cleaning and reduce the workload for residents.

[0003] However, despite the continuous improvement in the cleaning capabilities of robotic vacuum cleaners, the management of their cleaning components remains a pressing issue. This is especially true for robotic vacuum cleaners with integrated mopping functions; cleaning components such as mops and rollers need to be cleaned and dried promptly after use. Otherwise, bacteria can grow inside these components, significantly impacting the cleaning performance and potentially leading to mold growth and frequent replacement. Most robotic vacuum cleaners lack drying capabilities, requiring manual cleaning and drying of the components, which is time-consuming and labor-intensive. Therefore, a robotic vacuum cleaner with automatic drying capabilities is needed, allowing cleaning components to be reused after drying without the need for manual disassembly, washing, and air-drying, thus saving manpower and improving the user experience.

[0004] To address the inconvenience of manual cleaning of cleaning parts, existing technologies employ airflow duct structures to dry them. These systems typically use simple ducts and outlets facing the cleaning parts, allowing airflow to directly reach and dry them. The problem with this design is that, to accommodate the internal structure of the robotic vacuum cleaner and its base station, the duct structure cannot be designed with a sufficiently wide diameter, making it difficult for the airflow to completely cover the cleaning parts. Therefore, while this design can dry the parts to some extent, the uneven airflow coverage leads to low drying efficiency and poor results. It can even result in areas that are dried but then overheated, accelerating the aging of those areas.

[0005] Therefore, how to ensure that the air duct structure can evenly blow airflow onto the parts to be treated is an urgent problem to be solved. Utility Model Content

[0006] In the air duct structure, airflow is guided by a flow guide to cover the component to be processed, ensuring uniform coverage. Specifically, the flow guide can be connected to the air outlet of the air duct structure and is configured with a flow cross-section larger than that of the air outlet of the air duct. This allows the airflow to have a larger flow cross-section at the flow guide outlet and cover the component to be processed in front of the flow guide outlet. The problem is that when airflow passes through the guide, the airflow enters the guide through a duct structure with a relatively small flow cross-section. When the internal length of the guide is insufficient, the airflow cannot diffuse evenly inside the guide and cannot evenly cover the flow cross-section at the air outlet when it is blown out from the outlet, thus failing to evenly blow onto the component to be treated. When the internal length of the guide is sufficient to allow the airflow to diffuse fully inside the guide, the airflow speed will be reduced due to the excessive length of the guide, thereby reducing the efficiency of airflow treatment. Furthermore, an excessively long guide will occupy the space on the device it is installed on, affecting the design of other components on the device.

[0007] Therefore, how to provide a guide that can direct airflow into a uniform blowing direction onto the component to be treated is an urgent problem to be solved.

[0008] To solve the above-mentioned technical problems, the first aspect of this utility model provides a flow guide, comprising:

[0009] An air inlet and an air outlet with a cross-sectional area larger than the air inlet, wherein the air inlet is configured to be detachably connected to an air supply device and receive airflow generated by the air supply device, and the air outlet faces the component to be processed to deliver airflow to the component to be processed; and

[0010] A flow guide is provided between the air inlet and the air outlet along the flow direction to split the airflow into multiple streams distributed along the length of the component to be treated and guide the airflow toward the surface of the component to be treated.

[0011] In some embodiments, the system further includes a housing, with an air inlet and an air outlet disposed on both sides of the housing to form a channel for airflow.

[0012] In some embodiments, the device further includes a housing, with an air inlet and an air outlet disposed on both sides of the housing. The housing is mounted to the outer surface of the device on which the air guide is mounted, forming a channel for airflow to pass through.

[0013] In some embodiments, the flow guide is configured as a flow guide grille, wherein multiple grille plates in the flow guide grille are configured to extend along the flow direction and form an airflow channel between adjacent grille plates that allows airflow to pass through.

[0014] In some embodiments, the spacing between adjacent grid plates gradually increases along the flow direction to evenly distribute the blown airflow to different surface areas of the component to be treated.

[0015] In some embodiments, the grid plates are radially distributed and extend along the flow direction to guide the airflow uniformly to the surface of the component to be treated.

[0016] In some embodiments, multiple grille plates are radially distributed along the length of the air outlet with the center point of the air inlet as the origin, so as to uniformly guide the airflow to the surface of the component to be treated.

[0017] In some embodiments, the grid sheet includes a proximal first grid sheet and a proximal second grid sheet, wherein the length of the proximal second grid sheet is less than the length of the proximal first grid sheet, and the proximal first grid sheet and the proximal second grid sheet are distributed alternately.

[0018] In some embodiments, the grille has a first end near the air inlet and a second end near the air outlet, and the distance between the first end of the first grille near the air outlet is longer than the distance between the first end of the second grille near the air outlet, so as to split the airflow twice and guide the airflow to the component to be treated.

[0019] In some embodiments, an air inlet is provided, and one end of the air inlet is corresponding to the end of the air outlet in the length direction; the grille is divided into a proximal grille near the center point of the air inlet and a distal grille away from the center point of the air inlet. In the length direction of the air outlet, the proximal grille is radially distributed with the center point of the air inlet as the origin. The proximal grille includes a proximal first grille and a proximal second grille. The plurality of distal grilles have an inclination angle between themselves and the air outlet section of the air outlet, and the inclination angle gradually decreases in the direction away from the air inlet.

[0020] In some embodiments, the grid sheet further includes a distal first grid sheet, wherein the length of the proximal second grid sheet is less than the length of the distal first grid sheet, and the proximal second grid sheet is disposed between the proximal first grid sheets and / or between the proximal first grid sheet and the distal first grid sheet.

[0021] In some embodiments, the distal grid sheet further includes a distal second grid sheet with a length shorter than the distal first grid sheet, and the distal second grid sheet is disposed between the distal first grid sheets.

[0022] In some embodiments, the distance between the first ends of the proximal first grille and the distal first grille and the air outlet is longer than the distance between the first ends of the proximal second grille and the distal second grille and the air outlet, so as to split the airflow twice and guide the airflow to the component to be treated.

[0023] In some embodiments, each grille is configured such that the second end is at the same distance from the air outlet.

[0024] In some embodiments, there are two air inlets, which are respectively provided at both ends of the air outlet along the length direction; two sets of grilles are formed, and in the length direction of the air outlet, each set of grilles is radially distributed with the center point of each air inlet as the origin, so as to uniformly guide the airflow to the surface of the component to be treated.

[0025] In some embodiments, the airflow guide further includes baffle ribs, which surround one side of the air outlet section of the plurality of grilles facing away from the air outlet. The baffle ribs extend along the length of the air outlet and move from both ends toward the middle. The distance between the baffle ribs and the air outlet gradually decreases, so that the airflow in the two sets of grilles is symmetrically distributed.

[0026] In some embodiments, the baffle rib includes a first baffle segment and a second baffle segment connected to each other. The first baffle segment and the second baffle segment are symmetrically arranged and are respectively provided for two sets of grille plates. Among the distances between the baffle rib and the air outlet, the connection point of the first baffle segment and the second baffle segment is closest to the air outlet and is close to the air outlet.

[0027] In some embodiments, the housing extends outward from the air outlet and has an extension section. The extension section has a snap-fit ​​portion, which is adapted to snap onto an assembly connected to the component to be treated, so as to maintain the distance between the air outlet and the component to be treated.

[0028] In some embodiments, the snap-fit ​​portion is adapted to snap-fit ​​with the mating portion on the assembly, and multiple snap-fit ​​portions are provided, which are arranged at intervals along the length direction of the air outlet;

[0029] The extension section and the mating part are spaced apart, so that the airflow from the air outlet can flow through the gap between the extension section and the mating part toward multiple snap-fit ​​parts, and then through the gap between the multiple snap-fit ​​parts toward the component to be processed.

[0030] In some embodiments, each snap-fit ​​portion includes a snap-fit ​​boss protruding from the extension section, each snap-fit ​​boss having a snap-fit ​​surface facing the air outlet, the snap-fit ​​surface being inclined such that the distance between the snap-fit ​​surface and the air outlet gradually increases along the protrusion direction.

[0031] The second aspect of this utility model provides a water tank assembly, comprising:

[0032] Storage cavity;

[0033] The aforementioned flow guide is disposed on the periphery of the storage cavity, such that at least a portion of the airflow delivered to the component to be processed can flow through the outer periphery of the storage cavity.

[0034] In some embodiments, the device further includes a housing body, a storage cavity disposed on the housing body, a flow guide disposed on the outside of the housing body and forming an airflow channel together with the housing body, and an air inlet channel disposed inside the housing body;

[0035] One side of the air guide is open to form an air outlet that connects to the airflow channel. An air inlet is provided on the side of the air guide opposite to the air outlet, and the air inlet connects the air inlet channel and the airflow channel.

[0036] In some embodiments, there are two air inlets; two air inlet channels are formed on the main body of the enclosure, the first end of the two air inlet channels is connected to the two air inlets one by one, and the second end of the two air inlet channels forms two first pairs of interfaces, which are located on the outer surface of the main body of the enclosure and are symmetrically arranged on both sides of the storage cavity.

[0037] A third aspect of this utility model provides a self-moving robot, which includes the water tank assembly described above.

[0038] The fourth aspect of this utility model provides a base station, comprising:

[0039] Base station main body;

[0040] The air supply device is installed on the main body of the base station;

[0041] The second pair of interfaces is connected to the air supply device and is adapted to connect with the first pair of interfaces of the aforementioned self-moving robot.

[0042] The fifth aspect of this utility model provides a cleaning system, including the aforementioned self-moving robot and the aforementioned base station.

[0043] The airflow guide provided by this utility model can guide the airflow through the airflow guide to be evenly distributed on the component to be processed, so that the airflow can process the component to be processed evenly, avoiding the asynchronous processing progress of different parts of the component to be processed caused by uneven airflow, thereby avoiding problems with the component to be processed and improving processing efficiency.

[0044] During use, the air guide is detachably connected to the air supply device via an air inlet, allowing the airflow generated by the air supply device to enter the air guide. This airflow enters the air guide through the air inlet, thus having a relatively small effective range. When this airflow contacts the air guide section, the air guide section can split the airflow with its small effective range into multiple streams distributed along the length of the component to be treated, thereby increasing the effective range of the airflow and uniformly guiding the airflow onto the component to be treated.

[0045] The air supply device can be any device capable of generating airflow and delivering it to a connected guide component, such as a fan. The guide component can be any device capable of splitting and guiding multiple airflow streams, such as a guide plate perpendicular to the flow direction and having multiple through holes to allow the airflow to be split into multiple streams. The through holes on the guide plate are arranged along the length of the component to be processed, so that the airflow can be split into multiple streams along the length of the component, thereby allowing the airflow to be evenly blown from the outlet onto the component to be processed.

[0046] By setting a guide section inside the guide component, the airflow that is fed into the guide component can be guided and diverted by the guide section, so that the airflow after passing through the guide section can be blown evenly from the air outlet to the part to be treated, and the part to be treated can be treated evenly, thereby improving the processing efficiency and preventing damage to the part to be treated due to uneven processing.

[0070] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0071] To solve the above-mentioned technical problems, the first aspect of this utility model provides a flow guide, such as... Figure 1 and Figure 4 As shown, it includes an air inlet 1, an air outlet 2, and a guide section.

[0072] The air inlet 1 is configured to be detachably connected to the air supply device and receive the airflow generated by the air supply device.

[0073] The air outlet 2 is configured with a cross-sectional area larger than that of the air inlet 1 and is directly facing the component 3 to be processed, so as to deliver airflow to the component 3 to be processed.

[0074] The air guide is disposed between the air inlet 1 and the air outlet 2 along the flow direction, so as to split the airflow into multiple streams distributed along the length direction of the component to be treated 3, and guide the airflow to blow onto the surface of the component to be treated 3.

[0075] The airflow guide provided by this utility model can guide the airflow through the airflow guide to be evenly distributed on the component 3 to be processed, so that the airflow can process the component 3 to be processed evenly, avoiding the asynchronous processing progress of different parts of the component 3 to be processed caused by uneven airflow, thereby avoiding problems with the component 3 to be processed and improving processing efficiency.

[0076] During use, the air guide is detachably connected to the air supply device via the air inlet 1 to allow airflow generated by the air supply device to enter the air guide. This airflow enters the air guide through the air inlet 1, thus having a relatively small effective range. When this airflow contacts the air guide, the air guide can divide the airflow with its small effective range into multiple streams distributed along the length of the component 3 to be treated, thereby increasing the effective range of the airflow and uniformly guiding the airflow onto the component 3 to be treated.

[0077] The component to be processed 3 can be any component that needs to be processed by airflow, such as a damp cleaning component. Taking "the component to be processed 3 includes a roller and a cloth covering the outer periphery of the roller" as an example, the airflow is divided into multiple streams distributed along the length direction of the component to be processed 3 by the guide and blown towards the roller to process the wet cloth on the outer periphery of the roller; the length direction of the component to be processed 3 is configured as the axial direction of the roller.

[0078] This airflow treatment method can be any treatment method that can be achieved through airflow, such as drying, heating, or cooling.

[0079] The air supply device can be any device capable of generating airflow and delivering it to a connected guide component, such as a fan. Furthermore, the air supply device can generate different airflows by adding additional modules, thereby achieving different airflow processing methods. For example, when the component 3 to be processed needs to be dried, a heating module can be added to the air supply device to generate airflow with a temperature higher than the ambient temperature through semiconductor heating principles or other methods, and blown onto the component 3 to be processed through the guide component for drying.

[0080] The airflow guide can be any device capable of splitting and guiding multiple airflow streams, such as a baffle plate. This baffle plate is perpendicular to the flow direction and has multiple through-holes to allow the airflow to be split into multiple streams. The through-holes on the baffle plate are arranged along the length of the component 3 to be processed, thus splitting the airflow into multiple streams along the length of the component 3, allowing the airflow to be evenly blown from the outlet 2 onto the component 3.

[0081] In some embodiments, such as Figure 6 and Figure 7 The air guide also includes a housing 4, with an air inlet 1 and an air outlet 2 located on both sides of the housing 4 to form a channel for airflow.

[0082] The housing 4 can be configured in any shape that can form an air duct, depending on the design requirements of the device to which the air guide is installed, such as an upwardly convex arc shape.

[0083] Through the outer casing 4, a channel for airflow can be formed between the air inlet 1 and the air outlet 2. This channel can ensure that the airflow in the guide can be constrained to flow between the air inlet 1 and the air outlet 2, thereby constraining the flow direction of the airflow in the guide. This allows the airflow to be diverted and guided through the guide section between the air inlet 1 and the air outlet 2, and finally blown evenly to the component to be processed.

[0084] Furthermore, the outer casing 4 can be formed as a sealed cavity and connected to the outside through the air inlet 1 and the air outlet 2. The sealed outer casing 4 ensures that the airflow in the channel formed between the air inlet 1 and the air outlet 2 enters only through the air inlet 1 and exits through the air outlet 2, thereby ensuring that the pressure of the airflow in the channel is stable and that all airflow enters from the air inlet 1. This, in turn, allows the airflow blown out of the air outlet 2 to maintain a stable pressure, and ensures that all airflow is supplied by the air supply device, thus guaranteeing a stable airflow processing process.

[0085] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it also includes a housing 4, an air inlet 1 and an air outlet 2 are disposed on both sides of the housing, a guide member has an outer surface that is mounted on the device, and the housing 4 is mounted to the outer surface of the guide member to form a channel for airflow.

[0086] The housing 4 can be configured in any shape that can form an air duct, depending on the design requirements of the device to which the air guide is installed, such as an upwardly convex arc shape.

[0087] The housing utilizes the air guide installed on the outer surface of the device, so that the air guide does not need to have a closed housing to form a channel for airflow. Instead, it forms a channel by cooperating with the outer surface of the device on which the air guide is installed, thereby reducing the space occupied by the air guide and facilitating the design of the device on which the air guide is installed.

[0088] In some embodiments, the flow guide further includes a sealing strip disposed on the portion of the flow guide that fits against the device on which the flow guide is mounted. When the flow guide is installed, the sealing strip is squeezed, thereby ensuring that the contact area between the flow guide and the outer surface of the self-moving robot is sealed when the flow guide and the outer surface of the device on which the flow guide is mounted form a channel. This prevents the contact area from being loose, which would cause the airflow in the channel to leak out from the contact area, resulting in uneven airflow blowing onto the component to be processed.

[0089] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the flow guide is located at the end of the flow guide along the flow direction.

[0090] By placing the guide section at the end of the guide component, the airflow can be directly blown onto the outer surface of the component to be treated after being guided and split by the guide section. This avoids mutual interference between the multiple airflows after splitting and guiding, as well as between the airflow after guidance and the inner wall of the guide component, which would weaken the guiding and splitting effect and thus affect the uniformity of the airflow.

[0091] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flow guide is configured as a flow guide grille, in which the grille plates 5 are configured to extend along the flow direction and form an airflow channel between adjacent grille plates 5 that allows airflow to pass through.

[0092] When the airflow passes through the guide grille, it enters multiple airflow channels and exits from them, thus being split into multiple streams. The flow direction of the airflow within the airflow channel is restricted by the grille 5 forming the channel to point towards the component 3 to be processed. Multiple grille 5 are arranged adjacently to form airflow channels that are adjacent to each other and whose outlets are arranged along the length of the component 3 to be processed. This allows the airflow to be guided into multiple streams distributed along the length of the component 3 to be processed, and to be evenly blown onto the component 3 to process it uniformly.

[0093] In some embodiments, such as Figure 4 and Figure 5 As shown, along the flow direction, the spacing between adjacent grid plates 5 gradually increases to evenly distribute the blown airflow to different surface areas of the component 3 to be treated.

[0094] Because the cross-sectional area of ​​the air inlet 1 is smaller than that of the air outlet 2, when using the existing arrangement of adjacent grille plates 5 arranged in parallel, the effective range of the airflow in contact with the guide section is consistent with the flow cross-section of the air inlet 1. This results in more airflow being guided in the airflow channels formed between the grille plates 5 near the air inlet 1, and less airflow in the airflow channels formed between the grille plates 5 far from the air inlet 1. This leads to uneven airflow blowing onto the component 3 to be processed, causing the part of the component 3 near the air inlet 1 to be processed to be finished while the part far from the air inlet 1 is still not finished. When uneven processing occurs, different consequences will occur to the component 3 to be processed depending on the processing method. For example, during drying, continuing to dry the already dried part may cause the dried part of the component 3 to be overheated, which may lead to damage to that part and a decrease in the efficiency of the component 3. However, if drying is not continued to prevent such a situation from occurring, other parts will not be effectively dried, resulting in low airflow processing efficiency.

[0095] Therefore, a guide section is needed that can evenly distribute the airflow and blow it onto the component 3 to be processed, so that all parts of the component 3 can be processed simultaneously.

[0096] When the airflow comes into contact with the grille 5, the grille 5, positioned in the direction of airflow, collides with and blocks the airflow, thereby slowing down the airflow and directing it towards the component 3 to be processed along both sides of the grille 5. With the above arrangement in this application, the grille 5 is arranged more densely closer to the air inlet 1 and more sparsely further away from the air inlet 1. When the airflow blows from the air inlet 1 to the guide grille in this application, the densely arranged grille 5 near the air inlet 1 causes the airflow blowing towards these grille 5 to be slowed down by colliding with the grille 5 and guided towards both sides of that portion of the grille 5, i.e., away from the air inlet 1. Meanwhile, the grille 5 further away from the air inlet 1 is relatively sparsely arranged, causing the airflow blowing towards that portion to collide less with the grille 5 and thus be slowed down less by the grille 5.

[0097] Therefore, through the above arrangement, the airflow in the airflow channel formed between the grille plates 5 near the air inlet 1 and the airflow in the airflow channel formed between the grille plates 5 away from the air inlet 1 can be balanced in terms of air volume and speed, so that the airflow can be evenly divided into multiple streams by each grille plate 5 and evenly processed by the treatment component 3.

[0098] In some embodiments, such as Figure 5 As shown, the grid plates 5 are radially distributed and extend along the flow direction to guide the airflow to the surface of the component 3 to be treated in a uniform manner.

[0099] By arranging the grille plates 5 in a radial pattern, multiple airflow channels composed of adjacent grille plates 5 can be formed, with relatively dense inlet arrangement and relatively loose outlet arrangement. When the airflow enters the guide section, even if the area of ​​the air inlet 1 is small, the densely arranged airflow channel inlets can ensure that the airflow enters each airflow channel, thereby guiding the airflow into multiple streams distributed along the length of the component 3 to be treated, so that it can be uniformly guided onto the component 3 to be treated.

[0100] In some embodiments, such as Figure 1 and Figure 5 As shown, along the length of the air outlet 2, multiple grille plates 5 are radially distributed with the center point of the air inlet 1 as the origin, so as to uniformly guide the airflow to the surface of the component 3 to be treated. It should be noted that the length direction of the air outlet 2 is configured to be the length direction of the component 3 to be treated.

[0101] When multiple grille plates 5 are radially distributed around the center point of the air inlet 1, and the airflow passes through the air inlet 1 and comes into contact with the grille plates 5, the end of each grille plate 5 closest to the air inlet 1 collides with the airflow, causing the airflow to be guided and blown onto the component 3 to be treated through the airflow channel formed between adjacent grille plates 5. The airflow channel formed by the radially arranged multiple grille plates 5 has a small inlet cross-sectional area and a large outlet cross-sectional area. Therefore, even when the cross-sectional area of ​​the air inlet 1 is smaller than that of the air outlet 2, the airflow entering the guide from the air inlet 1 can be guided to the cross-section of the air outlet 2, which can cover a larger area. This allows the airflow to be evenly blown onto all parts of the component 3 to be treated, achieving uniform treatment.

[0102] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, an air inlet 1 is provided, and one end of the air inlet 1 is corresponding to the end of the air outlet 2 along its length. Multiple grille plates 5 are divided into multiple proximal grille plates 51 near the center point of the air inlet 1 and multiple distal grille plates 52 away from the center point of the air inlet 1. Along the length of the air outlet 2, the multiple proximal grille plates 51 are radially distributed with the center point of the air inlet 1 as the origin, and the multiple distal grille plates 52 have an inclination angle relative to the air outlet cross-section of the air outlet 2, which gradually decreases in the direction away from the air inlet 1.

[0103] The air outlet 2 has a first end and a second end along its length. When there is only one air inlet 1, it is positioned offset from the centerline of the guide section along its length, such that the air inlet 1 is located on the side where the first end of the air outlet 2 is located, or on the side where the second end of the air outlet 2 is located, thus achieving a correspondence between the ends of the air inlet 1 and the air outlet 2 along their length. All the airflow generated by the air supply device is guided between adjacent grille plates 5 through a single air inlet 1. The fewer the number of air inlets 1, the simpler the connection structure between the air inlets 1 and the air supply device, and the easier it is for the air supply device to connect to the air inlet 1.

[0104] The air outlet section refers to the flow passage section of the air outlet 2. When the airflow passes through the air outlet section through the guide, it is blown out from the guide.

[0105] When the air inlet 1 is offset from the center point along the length of the guide section, the two farthest distal grille plates 52 are relatively far from the air inlet 1. If all grille plates 5 are radially distributed with the center point of the air inlet 1 as the origin, the airflow channel formed by the two distal grille plates 52 will be affected by partial obstruction from other distal grille plates 52, resulting in a reduction in the airflow received therein. When all distal grille plates 52 point to the center point of the air inlet 1, the airflow in each airflow channel can only be balanced by adjusting the length of the distal grille plates 52. The distal grille plates 52 configured as described above can adjust their tilt angle within a certain range, thereby enabling those skilled in the art to ensure that the airflow volume and velocity in the airflow channel formed by all adjacent distal grille plates 52 are basically the same by adjusting the tilt angle, thus ensuring that the airflow can be evenly blown onto the component 3 to be processed.

[0106] Although the guide section set in the above manner can guide the airflow evenly to the component 3 to be treated, in some cases, such as when the ratio of the cross-sectional area of ​​the air outlet 2 to the cross-sectional area of ​​the air inlet 1 is large, in order to achieve a uniform effect, a large number of grid plates 5 need to be set and a large number of airflow channels need to be formed. When the airflow moves in the airflow channels, it will be subject to frictional resistance and its speed will be reduced, thereby slowing down the speed of the airflow guided to the component 3 to be treated, resulting in a reduction in the airflow processing efficiency.

[0107] To address the above problems, in some embodiments, such as Figure 5 As shown, the grid plate 5 includes a proximal first grid plate 511, a distal first grid plate 521, and a proximal second grid plate 512, wherein the length of the proximal second grid plate 512 is less than that of the proximal first grid plate 511 and the distal first grid plate 521, and the proximal second grid plate 512 is disposed between the proximal first grid plates 511 and / or between the proximal first grid plates 511 and the distal first grid plate 521.

[0108] The airflow channels formed between adjacent proximal first grid plates 511, between adjacent distal first grid plates 521, and between adjacent proximal first grid plates 511 and distal first grid plates 521 constitute a first airflow channel. A proximal second grid plate 512 is disposed between the aforementioned first airflow channels to form a second airflow channel with the adjacent grid plates 5. Since this second airflow channel includes a proximal second grid plate 512, which is shorter in length than the proximal first grid plates 511 and distal first grid plates 521, the second airflow channel formed by the proximal second grid plate 512 and its adjacent grid plates 5 is shorter in the flow direction than the first airflow channel formed by the proximal first grid plates 511 and distal first grid plates 521. One or more proximal second grid plates 512 can be disposed in a first airflow channel to form one or more second airflow channels within the first airflow channel and with adjacent grid plates 5. Alternatively, the proximal second grid plates 512 may not be disposed in the first airflow channel to form a first airflow channel that does not include a second airflow channel.

[0109] When the airflow enters the guide section and comes into contact with the grid plate 5, the airflow enters the first airflow channel and the second airflow channel. By adjusting the number and position of the proximal second grid plates 512 in each of the first airflow channels, the airflow in the first airflow channel can be finely divided and guided, so that the guide section can uniformly guide the airflow to the component 3 to be processed.

[0110] Compared to setting grid plates 5 of uniform length to form airflow channels of uniform length in the flow direction, the arrangement of the first and second airflow channels in this application, by setting the second airflow channel with a shorter length in the flow direction, can reduce the time of airflow in the airflow channel formed by the grid plates 5 while ensuring the guiding effect, thereby reducing the frictional resistance caused by the airflow channel and increasing the speed of the airflow blown out from the guiding part to improve the processing efficiency.

[0111] In some embodiments, the distal grid plate 52 further includes a distal second grid plate with a length shorter than the distal first grid plate 521, and the distal second grid plate is disposed between the distal first grid plates 521.

[0112] When the airflow volume and velocity of the airflow flowing to the first airflow channel formed between the distal first grille plates 512 are high enough, one or more second airflow channels can be formed between the first airflow channels by setting one or more distal second grille plates.

[0113] Through this second airflow channel, the airflow can be guided and diverted again in the first airflow channel formed by the first grid plate 512 at the far end, so as to blow the airflow evenly to the component 3 to be processed.

[0114] In the first airflow channel, one or more near-end second grid plates 512 or far-end second grid plates may be provided to reduce the wind speed in the first airflow channel by arranging multiple second airflow channels.

[0115] In the first airflow channel where the wind speed is relatively low, the near-end second grid plate 512 or the far-end second grid plate may not be provided to prevent the added near-end second grid plate 512 or the far-end second grid plate from forming a second airflow channel and to reduce the wind speed in the first airflow channel.

[0116] With the above settings, the airflow can be divided by setting up fewer first airflow channels, and then the speed and direction of the airflow in the first airflow channels can be adjusted by arranging multiple second airflow channels.

[0117] Compared to setting an airflow channel that can cover the entire distance from the air inlet 1 to the air outlet 2 along the flow direction, the above setting method reduces the resistance of the airflow channel formed by the grid plate 5 to the airflow by setting a shorter second airflow channel, thereby making the airflow blow on the component to be treated at a higher speed and improving the processing efficiency.

[0118] The simultaneous setting of the first airflow channel and the second airflow channel also provides more adjustment space when designing the airflow guide grille. By adjusting the number and position of the second airflow channel, the wind speed and air volume of the airflow blown out from each airflow channel can be adjusted, so that the airflow can be blown more evenly onto the component 3 to be treated.

[0119] In some embodiments, such as Figure 4 and Figure 5 As shown, the grille 5 has a first end near the air inlet 1 and a second end near the air outlet 2. The distance between the first end of the near-end first grille 511 and the far-end first grille 521 and the air outlet 2 is longer than the distance between the first end of the near-end second grille 512 and the far-end second grille and the air outlet 2, so as to split the airflow twice and guide the airflow to the component 3 to be treated.

[0120] With the above arrangement, the first ends of adjacent proximal first grille 511 and distal first grille 521 form the inlet of a first airflow channel. The first ends of proximal second grille 512 and distal second grille, together with adjacent grille 5, form the inlet of a second airflow channel. Since the first ends of proximal first grille 511 and distal first grille 521 are closer to the air inlet 1 than the first ends of proximal second grille 512 and distal second grille, this first airflow channel has an inlet closer to the air inlet 1.

[0121] During use, airflow enters the first and second airflow channels formed in the guide grille through the air inlet 1, and is guided to be blown onto the component 3 to be treated. Because the first airflow channel has an inlet closer to the air inlet 1, it can receive the airflow from the air inlet 1 first and perform an initial airflow split. The airflow continues to move in its original direction in the first airflow channel and enters the second airflow channel for secondary guidance, finally being blown out from the outlet of the second airflow channel onto the component 3 to be treated.

[0122] The first airflow channel's initial diversion splits the gas as it exits the inlet 1, ensuring even distribution across multiple channels while minimizing the number of grille plates 5 to prevent excessive velocity loss during the initial diversion. The second airflow channel's second diversion further splits the diverted airflow into the first channels, creating channels with identical flow rates and velocities. By adjusting the spacing between the proximal first grille plates 511 and 512 forming the second airflow channels, the proportion of airflow entering each second airflow channel from the first channels, as well as the airflow velocity within the second channels, can be adjusted, ensuring uniform airflow onto the component 3 to be treated.

[0123] In some embodiments, such as Figure 5 and Figure 11 As shown, each grille piece 5 is set to have the same distance between its second end and the air outlet 2.

[0124] The second end of the grille 5, which is equidistant from the air outlet section, forms multiple outlets of the first airflow channel and the second airflow channel, so that the distance between the outlet of each first airflow channel and the air outlet section is equal, so that the airflow blown out from the first airflow channel and the second airflow channel is blown out at the same distance relative to the component to be treated 3.

[0125] By unifying the position of the airflow from the first and second airflow channels, the mutual interference between the airflows from each airflow channel can be reduced, thereby preventing the interference between multiple airflows, which could lead to a decrease in airflow speed or even uneven distribution.

[0126] In some embodiments, such as Figure 5 and Figure 11 As shown, the second end of each grille 5 is configured to extend to the air outlet section.

[0127] With the above configuration, the outlets of the first and second airflow channels coincide with the air outlet cross-section, meaning the airflow through the guide section can directly blow onto the component 3 to be treated. By shortening the distance between the outlets of the first and second airflow channels and the component 3 to be treated, the airflow, after being guided into multiple streams distributed along the length of the component 3, can immediately blow onto the component 3. When the outlets of the first and second airflow channels are too far from the component 3 to be treated, some of the airflow that has already been diverted and guided will blow from the sides of the air outlet 2 to the sides of the component 3 to be treated, instead of onto the component 3, resulting in waste. The above configuration can avoid this problem, thereby improving the utilization rate of airflow and thus improving processing efficiency.

[0128] Normally, the airflow guide provided by the combination of the near-end grille 51 and the far-end grille 52 can effectively guide the airflow evenly to the component 3 to be treated. However, in some special cases, such as when the ratio of the flow cross-sectional area of ​​the air outlet 2 to the flow cross-sectional area of ​​the air inlet 1 is large, since the air inlet 1 is located at one end of the length direction of the air outlet 2, the other end of the length direction of the air outlet 2 is far from the air inlet 1. The airflow may not be guided to this area, or very little airflow may be guided to this area, thus failing to achieve the goal of evenly guiding the airflow to the component 3 to be treated.

[0129] To address the above problems, in some embodiments, such as Figures 10 to 12 As shown, there are two air inlets 1, which are respectively set at both ends of the length direction of the air outlet 2; multiple grille plates 5 form two groups and are set corresponding to the two air inlets 1. In the length direction of the air outlet 2, with the center point of the air inlet 1 as the origin, the multiple grille plates 5 of each group are radially distributed to guide the airflow evenly to the surface of the component 3 to be treated.

[0130] The air outlet 2 has a first end and a second end along its length. When there are two air inlets 1, the two air inlets 1 are symmetrically distributed relative to the central axis of the guide section along the length of the air outlet 2, so that one air inlet 1 is set to the first end of the air outlet 2 and the other air inlet 1 is set to the second end of the air outlet 2; in this way, the airflow input by the air supply device can be symmetrically guided into the two sets of grille plates 5 by the two air inlets 1 respectively.

[0131] By setting two air inlets 1, air can be introduced from both sides, thereby increasing the air intake area and air volume. When the airflow flows in from the two air inlets 1, it will be guided towards the central area of ​​the air outlet 2 by multiple grilles 5 on the corresponding sides. Compared with single-sided air intake, in the scheme of air intake from both sides, the airflow distance along the length of the air outlet 2 is shorter and the flow resistance encountered by the airflow is less. This ensures that the gas flow rate and velocity at both ends of the air outlet 2 are relatively balanced with the central area, and thus ensures that the airflow flows out evenly from all positions of the air outlet 2, so that the airflow is evenly blown onto the component 3 to be processed.

[0132] Furthermore, each set of grille plates 5 corresponds to one air inlet 1. Since the airflow travels a shorter distance along the length of the air outlet 2, the number of grille plates 5 in each set of grille plates 5 can be reduced, resulting in fewer bars required for each set of grille plates 5 and a larger airflow between adjacent grille plates 5. At the same time, the fewer grille plates 5 present less flow resistance to the airflow, further increasing the airflow and velocity from the air outlet 2. Moreover, the airflow and velocity at each point of the air outlet 2 are relatively balanced, thereby improving the processing efficiency of the component 3 to be processed and ensuring that the airflow is evenly blown onto the component 3 to be processed.

[0133] Meanwhile, along the length of the air outlet 2, the two sets of grille plates 5 are symmetrically arranged. Thus, the airflow output from the two air inlets 2 is subjected to equal resistance and guidance during the flow process of passing through the two sets of grille plates 5 respectively. Furthermore, multiple grille plates 5 in each set are evenly arranged along the length of the air outlet 2, thereby further balancing the gas flow rate and velocity at various points of the air outlet 2, and further realizing that the airflow is evenly blown onto the component 3 to be treated.

[0134] In some embodiments, combined with Figures 10 to 12 As shown, the airflow guide also includes a baffle 6. The baffle 6 surrounds one side of the air outlet section of the multiple grille plates 5 facing away from the air outlet 2. The baffle 6 extends along the length of the air outlet 2 and moves from both ends toward the middle. The distance between the baffle 6 and the air outlet 2 gradually decreases.

[0135] When the outer casing 4 is installed onto the outer surface of the device on which the airflow guide is installed, the baffle 6 and the multiple grid plates 5 are located on the same surface of the outer casing 4, or the baffle 6 protrudes from the outer surface of the device on which the airflow guide is installed, abutting against the surface where the multiple grid plates 5 are located. By setting the baffle 6, the space between the outer casing 4 and the device on which the airflow guide is installed is separated into a channel space for airflow and an installation space for the arrangement of other structures. The height of the multiple grid plates 5 protruding from the outer casing 4 is the same as the height of the baffle 6 protruding from the outer casing 4. The multiple grid plates 5 divide the channel space into multiple airflow channels, ensuring the independence of each airflow channel, thereby making the airflow blown onto the component 3 to be treated more uniform.

[0136] Furthermore, the distance between the baffle 6 and the air outlet 2 gradually decreases from both ends toward the middle. The baffle 6 is roughly arc-shaped, with its middle part protruding toward the air outlet 2. The baffle 6 can constrain the airflow entering from the air inlet 1, directing the airflow toward one side of the multiple grille plates 5. Moreover, the baffle 6 can also form an airflow channel with the grille plate 5 located at the farthest position in each group of grille plates 5, guiding the airflow that does not enter the airflow channel between adjacent grille plates 5 toward the middle of the air outlet 2 under the guidance of the baffle 6. This makes the airflow of the grille plates 5 near the air inlet 1 and the grille plates 5 far from the air inlet 1 more uniform, thus ensuring a more uniform airflow at all points of the air outlet 2.

[0137] In some embodiments, please refer to Figures 10 to 12 The baffle 6 includes a first baffle section 61 and a second baffle section 62 connected to each other. The first baffle section 61 and the second baffle section 62 are symmetrically arranged and are respectively set for two sets of grille plates 5. In the distance between the baffle 6 and the air outlet section of the air outlet 2, the connection point of the first baffle section and the second baffle section is closest to the air outlet 2 and is close to the air outlet 2.

[0138] Therefore, along the length of the air outlet 2, the baffle 6 is divided into a first baffle section 61 and a second baffle section 62 from its center position, and is respectively set for the two air inlets 1, so as to guide the airflow entering from the corresponding air inlet 1 to the corresponding set of grille plates 5. Taking the attached figure as an example, the left area is the first baffle section 61, and the right area is the second baffle section 62.

[0139] The first baffle section 61 and the second baffle section 62 have the same shape and are both arc-shaped. Both have connected proximal ends and opposing distal ends. The distance between the first baffle section 61 and the air outlet 2 gradually decreases from its distal end towards its proximal end. Similarly, the distance between the second baffle section 62 and the air outlet 2 gradually decreases from its distal end towards its proximal end. This arrangement allows airflow that does not enter between adjacent grille plates 5 to flow more effectively towards the air outlet 2 under the guidance of the first and second baffle sections. Furthermore, an airflow channel is formed between the baffle rib 6 and the grille plate 5 furthest from the air inlet 1 in the corresponding central area of ​​the air outlet. This balances the airflow into the grille plate 5 near and away from the air inlet 1, ensuring more uniform airflow throughout the air outlet 2.

[0140] Furthermore, the first partition section 61 and the second partition section 62 are symmetrically arranged. The airflow entering from the two air inlets 1 has the same guiding effect at the first partition section 61 and the second partition section 62, so that the airflow enters the two sets of grille plates 5 with the same flow rate and velocity. At the same time, since the two sets of grille plates 5 are also symmetrically distributed, the airflow in the two sets of grille plates 5 will also be symmetrically distributed.

[0141] The connection between the first baffle section 61 and the second baffle section 62 cannot be completely flush with or protrude from the air outlet 2. This may result in the connection between the first baffle section 61 and the second baffle section 62 at least partially blocking the air outlet 2, causing no airflow through the central area of ​​the air outlet 2, creating an air outlet blind zone, and consequently leading to uneven processing of the components 3 to be processed.

[0142] Therefore, in the distance between the baffle 6 and the air outlet 2, the connection between the first baffle section and the second baffle section is closest to the air outlet 2. At this time, there is still a certain gap between the connection between the first baffle section 61 and the second baffle section 62 and the air outlet section, so as to ensure that a part of the airflow entering from the two air inlets 1 can flow to the air outlet 2 through the gap. In other words, the airflow guided by the first baffle section 61 and the second baffle section 62 can partially overlap in the central area of ​​the air outlet 2, so as to ensure that there is airflow output in the central area of ​​the air outlet 2, thereby ensuring that the airflow from the air outlet 2 is uniform.

[0143] However, the gap between the connection between the first baffle section 61 and the second baffle section 62 and the air outlet section should not be too large. When the gap is too large, the air flow output from the central area of ​​the air outlet 2 will be concentrated, resulting in a larger flow in the central area of ​​the air outlet 2 and causing an imbalance in the air flow at various points of the air outlet 2.

[0144] When there are two air inlets 1, the specific arrangement of each set of grille plates 5 is similar to that of the grille plates 5 in a single air inlet 1. In this case, the distal grille plate 52 is not required; the grille plates 5 may only include the aforementioned proximal first grille plate 511 and proximal second grille plate 512. The proximal first grille plate 511 and proximal second grille plate 512 are alternately distributed, with the airflow channel formed between adjacent proximal first grille plates 511 serving as the first airflow channel. The proximal second grille plate 512 is positioned between the first airflow channels to form a second airflow channel with the adjacent grille plates 5. The arrangement method and principle of the proximal first grille plate 511 and proximal second grille plate 512 have been described above and will not be repeated here.

[0145] In some embodiments, combined with Figures 10 to 12 As shown, the outer casing 4 extends outward from the air outlet 2 and is provided with an extension section 41. The extension section 41 is provided with a snap-fit ​​part 42, which is adapted to be snapped onto the fitting connected to the component to be processed 3, so as to maintain the distance between the air outlet 2 and the component to be processed 3.

[0146] The air outlet 2 faces outward relative to the outer casing 4 itself. The inner part of the outer casing 4 is considered the inside, and the edge of the outer casing is considered the outside. The direction from the middle of the outer casing 4 towards its edge is from the inside to the outside. The extension section 41 protrudes from the air outlet 2 and extends outward. The length of the extension section 41 is less than or equal to the length of the air outlet 2 to ensure that the locking part 42 has sufficient installation space and locking strength, while also minimizing the amount of obstruction to the air outlet 2.

[0147] The fitting connected to the component 3 to be treated is any component that can be directly or indirectly connected to the component 3 to be treated, such as a cleaning cover. At least a portion of the fitting can extend into the gap area between the air outlet 2 and the component 3 to be treated, so as to engage with the locking part 42. Since the relative position of the fitting and the component 3 to be treated is fixed, the locking part 42 is used to lock the fitting, thereby ensuring the relative position of the locking part 42 and the component 3 to be treated. This better ensures the relative position of the air outlet 2 and the component 3 to be treated, and thus better prevents the component 3 to be treated from shifting during processing. For example, when the cleaning roller brush is placed on the base station, the cleaning component is easily shifted under the torsional force of the surrounding water pipe or the force of the spring, which causes the airflow blown from the air outlet 2 to not blow onto the component 3 to be treated effectively, thus affecting the processing effect of the airflow blown from the air outlet 2.

[0148] In some embodiments, the snap-fit ​​portion 42 is adapted to snap-fit ​​with the mating portion on the assembly. Multiple snap-fit ​​portions 42 are provided and are spaced apart along the length direction of the air outlet 2. The extension section 41 is spaced apart from the mating portion, so that the airflow from the air outlet 2 can flow toward the multiple snap-fit ​​portions 42 through the gap between the extension section 41 and the mating portion, and flow toward the component to be processed 3 through the gap between the multiple snap-fit ​​portions 42.

[0149] Since the latching part 42 is located between the air outlet 2 and the component to be treated 3, it obstructs the airflow from the air outlet 2, affecting the airflow rate to the component to be treated 3 and thus the treatment effect. By providing multiple latching parts 42, with the spacing between adjacent latching parts 42 forming a channel for airflow, the airflow can flow more effectively to the component to be treated 3. Simultaneously, multiple latching parts 42 can further divert the airflow, and being closer to the component to be treated 3, the airflow can be more evenly distributed onto the component to be treated 3. Furthermore, the aforementioned near-end grille 51 and far-end grille 52 have an angle of inclination with the air outlet section, so the airflow direction from the air outlet 2 is not completely perpendicular to the air outlet section, but rather has an angle of inclination with it. By having multiple snap-fit ​​parts 42 positioned directly on the component 3 to be processed, the airflow can be further diverted and guided, allowing the airflow to blow vertically toward the component 3 to be processed, avoiding excessive concentration of airflow in the middle, and enabling the airflow to blow more evenly onto all parts of the component 3 to be processed, thus achieving uniform processing.

[0150] In some embodiments, among the plurality of snap-fit ​​portions 42, one snap-fit ​​portion 42 may be added at each of the two snap-fit ​​portions 42 located at both ends of the extension section 41 along its length. Since the extension section 41 is cantilevered, the snap-fit ​​strength at both ends along its length is relatively weak. By adding snap-fit ​​portions 41, the snap-fit ​​strength at both ends along its length can be improved, thus better ensuring the relative position of the snap-fit ​​portion 42 and the component 3 to be processed.

[0151] In some embodiments, each latching portion 42 includes a latching boss 421 protruding from the extension section 41. Each latching boss 421 has a latching surface facing the air outlet 2. The latching surface is inclined such that the distance between the latching surface and the air outlet 2 gradually increases along the protrusion direction.

[0152] The multiple snap-fit ​​bosses 421 are all the same in shape and size, which makes it less likely for local shrinkage to occur during the manufacturing process of the outer shell 4, thus affecting the overall strength of the outer shell 4. The mating part on the assembly is configured as a mating arm 31, which extends in an arc shape and has two arc-shaped surfaces. At least a portion of the mating arm 31 extends into the gap between the air outlet 2 and the part to be treated 3, such that the two arc-shaped surfaces face the part to be treated 3 and the air outlet 2, respectively. Multiple snap-fit ​​parts 42 snap onto the arc-shaped surface of the mating arm 31 on the side of the mating arm 31 facing the part to be treated 3 from the end of the mating arm 31. Furthermore, the snap-fit ​​surfaces of the multiple snap-fit ​​protrusions 421 are all inclined, tilting towards the side closer to the component 3 to be processed. When the guide component is assembled with the component 3 to be processed, since the distance between the top of each snap-fit ​​surface in its protruding direction and the air outlet 2 is the largest, it is easier to snap onto the side of the mating arm 31 facing the component 3 to be processed. Then, under the guidance of the multiple snap-fit ​​surfaces, the multiple snap-fit ​​protrusions 421 can enter the side of the mating arm 31 facing the component 3 to be processed more smoothly, making the assembly operation more labor-saving and convenient.

[0153] In summary, the airflow guide provided by this utility model, when connected to an external air supply device, can divert and guide the airflow entering from the air inlet 1 through the internal airflow guide section, so that the airflow is evenly blown onto the component 3 to be treated. The airflow guide section, by being radially distributed and configured with a near-end grid plate 51 and a far-end grid plate 52, ensures that even when the air inlet 1 is deviated from the center of the airflow guide section along its length, the airflow in the air inlet 1 can still be diverted and guided to be evenly blown onto the component 3 to be treated. Alternatively, the airflow guide section can be configured with two sets of grid plates 5, so that the airflow entering from the two symmetrically distributed air inlets 1 can be evenly blown onto the component 3 to be treated under the diversion and guidance of the two sets of grid plates 5. Meanwhile, by setting a first grid plate 511, a second grid plate 512, and / or a first grid plate 521 and a second grid plate 521 at the far end, a first airflow channel and a second airflow channel are formed to reduce the speed loss of airflow through the guide section, thereby achieving a higher speed when blown to the component 3 to be processed, and thus improving the efficiency of airflow processing.

[0154] The second aspect of this utility model provides a water tank assembly, combined with Figure 8 and Figure 9 As shown, it includes the aforementioned flow guide and storage cavity. The flow guide is disposed on the periphery of the storage cavity 71, such that the airflow delivered to the component to be processed 3 can at least partially flow through the outer periphery of the storage cavity 71.

[0155] The storage cavity 71 is a hollow cavity that can be used to store liquids or solids, such as cleaning fluid or cleaning blocks. The shape and size of the storage cavity 71 are not specifically limited and can be specifically designed according to the size and dimensions of the device to be installed.

[0156] The guide can form part of the cavity wall of the storage cavity 71, so that the guide is closer to the stored item in the storage cavity 71, and the effect of the airflow on the stored item is better when it flows through the guide. Alternatively, the guide is at least partially spaced from the storage cavity 71 to form an airflow channel between the guide and the outer wall of the storage cavity 71 for the airflow to be blown toward the component 3 to pass through.

[0157] By placing the airflow guide around the periphery of the storage cavity 71, the airflow generated by the air supply device is transported to the component 3 to be processed via the airflow guide. Since the airflow can pass through the outer periphery of the storage cavity 71, it can act on the storage cavity 71 and the contents within it. For example, when the storage cavity 71 contains clean water, and a heating module is added to the air supply device, making the airflow generated by the air supply device hot, the hot airflow can heat the storage cavity 71 and the clean water stored inside as it passes through the outer periphery of the storage cavity 71. This heated water can then be used for hot water cleaning or other hot water applications. This arrangement eliminates the need for an additional heating module outside the storage cavity 71, simplifying the structure of the water tank assembly and reducing costs.

[0158] In some embodiments, combined with Figure 9 and Figure 13 As shown, the water tank assembly also includes a tank body 7, a storage cavity is disposed on the tank body 7, a flow guide is disposed on the outside of the tank body 7 and together with the tank body 7 forms an airflow channel, and an air inlet channel is disposed inside the tank body 7; one side of the flow guide is open to form an air outlet 2 that connects to the airflow channel, and an air inlet 1 is disposed on the side of the flow guide opposite to the air outlet 2, and the air inlet 1 connects the air inlet channel and the airflow channel.

[0159] The flow guide is installed on the outside of the box body 7, and an outer side wall of the box body 7 forms a mating surface that is spaced apart from the flow guide. For example, when the flow guide is installed at the bottom of the box body 7, the mating surface is the bottom surface of the box body 7. The free ends of each grid plate 5 of the flow guide abut against this mating surface, so that the free ends of adjacent grid plates 5 can be closed through the mating surface, thereby forming an airflow channel between adjacent grid plates 5 that allows airflow to pass through.

[0160] An opening is provided on the mating surface of the main body 7, and an air inlet 1 is connected to this opening. The number of openings corresponds to the number of air inlets 1. When there is one air inlet 1, there is one corresponding opening; when there are two air inlets 1, there are two corresponding openings, and the two air inlets 1 are connected to the two openings in a one-to-one correspondence. The air outlet 2 is located at the lateral edge of the mating surface, and the gap between the guide and the edge of the mating surface forms the air outlet 2.

[0161] Airflow enters at inlet 1 perpendicular to the mating surface. Guided and diverted by the grille 5, it flows parallel to the mating surface towards outlet 2. After entering the guide component, the airflow changes from perpendicular to the mating surface to parallel to it. This arrangement effectively reduces the size of the water tank assembly in the direction perpendicular to the mating surface, saving space. If the airflow direction is not changed, inlet 1 and outlet 2 would be arranged sequentially perpendicular to the airflow, and a guide component would be provided between them. To ensure the guide component effectively diverts the airflow, it needs a certain length in the airflow direction. This would result in a certain distance between inlet 1 and outlet 2, making the size of the water tank body relatively large in the direction perpendicular to the mating surface.

[0162] By changing the airflow direction, the orientation of the air inlet 1 and the air outlet 2 are made to be different, thus reducing the size requirement of the airflow conduction structure perpendicular to the air inlet. Simultaneously, after changing the airflow direction, the air outlet 2 is positioned on the side of the main body 7 with a relatively larger dimension on the plane of the mating surface (referred to as the side along the length direction of the main body 7). This allows the air outlet 2 to extend more effectively along the length direction of the main body 7, corresponding to the length direction of the component to be treated 3. Therefore, the size of the air outlet 2 can be relatively larger, with a larger air outlet area, better covering all parts along the length direction of the component to be treated 3, resulting in a smaller overall water tank assembly and saving more space.

[0163] In some embodiments, combined with Figure 8 and Figure 14 As shown, when there are two air inlets 1, two air inlet channels are formed on the main body 7. The first end of the two air inlet channels is connected to the two air inlets 1 in a one-to-one correspondence. The second end of the two air inlet channels forms two first pairs of interfaces 72. The two first pairs of interfaces 72 are located on the outer surface of the main body 7 and are symmetrically arranged on both sides of the storage cavity 71.

[0164] Each air inlet channel has two openings, located at the first and second ends of each channel. The opening at the first end of each air inlet channel is connected to the air inlet 1, and the opening at the second end of each air inlet channel is configured as a first pair of interfaces 72. The first pair of interfaces 72 are located on the outer surface of the main body 7 to facilitate connection with the air supply device. The airflow generated by the air supply device can enter the corresponding air inlet channel through the first pair of interfaces 72, and then be conveyed to the corresponding air inlet 1. Under the guidance and diversion effect of the grille plates 5, the airflow is finally evenly blown from the outlet 2 onto the component 3 to be treated.

[0165] Furthermore, both first pairs of interfaces 72 are connected to the air supply device, allowing air to enter the two air inlet channels simultaneously. When the airflow passes through the outer periphery of the storage cavity 71, the flow path of the airflow within the guide member is relatively shorter compared to the single-sided air supply configuration, resulting in less airflow loss and a better effect on the storage cavity 71 and the stored items within it. For example, the air supply device generates hot airflow to guide it into each air inlet channel. The airflow entering the two air inlets 1 flows simultaneously towards the guide member. When the airflow flows along the plane of the mating surface, the airflow on both sides flows towards the center simultaneously. The flow path of the airflow along the plane of the mating surface is shorter, resulting in less heat loss. Therefore, the heating effect on the stored items within the storage cavity 71 is better.

[0166] In some embodiments, the water tank assembly is configured such that the flow guide is located at the bottom of the storage chamber 71 during normal use.

[0167] The airflow guide can form a bottom protective element of the main body 7 of the container. In some cases, placing the airflow guide at the bottom of the storage cavity 71 can make the airflow passing through the airflow guide more effective in heating the stored items inside the storage cavity 71. For example, when hot air flows through the airflow guide, the heat of the hot air will be conducted upwards, thus making the heating effect on the stored items more significant.

[0168] In summary, the water tank assembly provided by this utility model, when connected to an external air supply device, can transmit the airflow generated by the air supply device through the air inlet channel to the guide component, and the airflow is diverted and guided by the grid plates 5 on the guide component, so that the airflow is evenly blown onto the component 3 to be treated. At the same time, when the airflow flows through the guide component, the airflow can also act on the stored items in the storage cavity 71. For example, the hot airflow can heat the liquid in the storage cavity 71, so that the water tank assembly can better heat the stored liquid without setting a heating component. Thus, the water tank assembly can provide hot liquid to achieve thermal cleaning or thermal dissolution of solid cleaning materials, thereby achieving multi-functionality of the water tank assembly while simplifying the structure of the water tank assembly. Moreover, by setting two first pair of interfaces 72, the airflow path can be shortened, resulting in less airflow loss, a larger airflow from the air outlet 2, and a better effect on the storage cavity 71 and its stored items.

[0169] A third aspect of this utility model provides a self-moving robot, which includes the water tank assembly described above.

[0170] By incorporating the aforementioned water tank assembly, the self-propelled robot can connect an air supply device to a guide member via the first pair of interfaces 72, directing the airflow evenly onto the component 3 to be processed on the self-propelled robot, thereby treating the component 3 through airflow. Simultaneously, the cleaning fluid required for the self-propelled robot's cleaning process can be stored in the storage chamber 71 of the water tank assembly.

[0171] Among them, the above-mentioned component 3 to be processed can be any component that can be processed by air flow, such as a wet cleaning part. After the cleaning part of the self-moving robot finishes the cleaning work and is cleaned, it can be dried by the air flow blown out from the air outlet 2 of the self-guiding part.

[0172] The treatment by the above-mentioned air flow can be any treatment method that air flow can perform, such as drying the cleaning part.

[0173] In some embodiments, the box body 7 of the water tank assembly can be integrally provided with the housing of the self-moving robot, and the guiding part forms the bottom housing of the self-moving robot. The storage cavity 71 is detachably arranged on the box body 7, which is convenient for taking out and injecting storage items. The air inlet channel on the box body 7 is arranged inside the self-moving robot. One end of the air inlet channel is connected to the air inlet 1 of the guiding part, and the other end is connected to the air supply device arranged outside, so as to transport the air flow generated by the external air supply device to the guiding part and evenly blow it onto the component 3 to be processed on the self-moving robot.

[0174] By setting the built-in air inlet channel, the self-moving robot can automatically receive the air flow when it is connected to the external air supply device, and process the component 3 to be processed on the self-moving robot through the air flow. At the same time, by setting the built-in air inlet channel, the external air supply device does not need to set a duct structure connected to the air inlet 1 of the guiding part, thus saving the floor space of the air supply device.

[0175] To sum up, by setting the water tank assembly, the self-moving robot can make the air flow quickly and evenly process the component 3 to be processed on it through the guiding part of the water tank assembly, and the air flow can conduct heat on the storage items in its storage cavity, so that the storage items do not need to be provided with a separate heating component, which saves more costs. At the same time, through the air inlet channel used in cooperation with the guiding part, the external air supply device used in supporting the self-moving robot can also have a smaller floor area.

[0176] The fourth aspect of the present utility model provides a base station, which is suitable for being used in cooperation with the above-mentioned self-moving robot. The base station includes a base station body, an air supply device, and a second docking interface.

[0177] The air supply device is arranged on the base station body and is used for generating air flow.

[0178] The second docking interface is communicated with the air supply device and is suitable for being docked and communicated with the first docking interface 72 of the self-moving robot.

[0179] The base station provided by this invention enables the first pair of interfaces 72 on the self-mobile robot to connect with the second pair of interfaces on the base station when the self-mobile robot moves to or near the base station. An airflow device generates airflow that flows through the second pair of interfaces to the first pair of interfaces 72, and then enters the air intake channel within the self-mobile robot. The airflow is guided through the air intake channel to the guide components of the self-mobile robot, allowing it to be evenly blown from the air outlet 2 onto the component 3 to be processed. The airflow blowing onto the component 3 is not directly blown out of the base station, but rather enters the self-mobile robot through the air intake channel after the first pair of interfaces 72 and the second pair of interfaces are connected, and then exits from the air outlet 2 on the self-mobile robot. This eliminates the need for a complex airflow guiding structure on the base station body, making the base station structure relatively simpler. Furthermore, since the air outlet 2 is located on the self-mobile robot, it can be positioned closer to the component 3 to be processed, resulting in higher airflow efficiency. Furthermore, the airflow is guided to be evenly distributed onto the component 3 to be processed by the airflow guide, so that the airflow can evenly process the component 3 to be processed and improve the processing efficiency.

[0180] The base station body can be configured in any shape that facilitates the placement of the autonomous mobile robot. The base station body must have at least a placement platform or accommodating cavity for the autonomous mobile robot. The base station body enables functions such as cleaning the components to be processed by the autonomous mobile robot and / or charging the autonomous mobile robot.

[0181] The air supply device can be installed inside the base station body for a more compact structure. Alternatively, the air supply device can be detachably installed on one side of the base station body for easy maintenance. The air supply device can be any device capable of generating airflow and delivering it to a connected guide component, such as a fan or pump. Furthermore, the air supply device can generate different airflows by adding additional modules, thereby achieving different airflow processing methods. For example, when the component 3 to be processed needs to be dried, a heating module can be added to the air supply device to generate airflow at a temperature higher than the ambient temperature through semiconductor heating principles or other methods. This airflow is then guided from the air intake channel inside the mobile robot into the guide component and blown onto the component 3 to be processed for drying.

[0182] The number of the second pair of interfaces is the same as the number of the first pair of interfaces 72. When there is one interface in the first pair of interfaces 72, there is one interface in the second pair of interfaces; when there are two interfaces in the second pair of interfaces 72, there are two interfaces in the second pair of interfaces. When the self-propelled robot docks at the base station, the first pair of interfaces 72 and the second pair of interfaces automatically connect and communicate, ensuring that the airflow generated by the air supply device can flow into the self-propelled robot.

[0183] In some embodiments, sealing rings are provided at the first pair of interfaces 72 and / or the second pair of interfaces. When the first pair of interfaces 72 and the second pair of interfaces are aligned, the first pair of interfaces 72 is fitted over the outside of the second pair of interfaces and presses against the sealing ring located between the first pair of interfaces 72 and the second pair of interfaces; or, the second pair of interfaces is fitted over the outside of the first pair of interfaces 72 and presses against the sealing ring located between the first pair of interfaces 72 and the second pair of interfaces; or, sealing rings are provided at the mating ends of both the first pair of interfaces 72 and the second pair of interfaces, and when they approach each other, the two sealing rings press against each other to form a seal at the mating point. This prevents airflow from leaking out from the mating point of the first pair of interfaces 72 and the second pair of interfaces, which would cause significant airflow loss, affect the airflow volume at the air outlet 2, and consequently affect the processing efficiency of the component 3 to be processed.

[0184] In summary, when the base station provided by this utility model is connected to the self-moving robot, it can automatically connect and communicate with the first pair of interfaces 72 on the self-moving robot through the second pair of interfaces. The air supply device delivers airflow from the second pair of interfaces to the first pair of interfaces 72, so that the airflow can enter the air intake channel inside the self-moving robot from the first pair of interfaces 72. Then, the airflow is diverted and guided by the guide component on the self-moving robot, so that the airflow can be blown evenly to the component 3 to be processed. The processing efficiency of the component 3 to be processed is higher, and the air duct structure inside the base station is simplified, making the overall structure of the base station simpler.

[0185] The fifth aspect of this utility model provides a cleaning system, including the aforementioned self-moving robot and the aforementioned base station.

[0186] The cleaning system provided by this invention features a water tank assembly on the self-moving robot. This assembly not only stores cleaning fluid and other materials, but also uses a guide component to divert and guide airflow, ensuring even distribution of the airflow to the component 3 to be treated, resulting in better processing. Furthermore, the airflow through the guide component can simultaneously heat the stored materials, enhancing their effectiveness, such as through thermal cleaning. This improves the cleaning capability of the self-moving robot without requiring a separate heating module, thus reducing costs. Additionally, the base station can connect to the first pair of interfaces 71 on the self-moving robot via a second pair of interfaces, allowing airflow from the base station's ventilation device to better enter the robot. The airflow is then conducted to the guide component through the robot's internal air intake channel, bringing the air outlet 2 closer to the component 3, improving processing efficiency and simplifying the base station's structure.
