Detailed Implementation

[0051] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0053] In related technologies, to accommodate the limited installation space in cleaning equipment, flow channel components are generally designed as plate-like structures with the internal flow channels extending in basically parallel directions. However, in order to have a larger fluid supply area, the flow direction of some branch channels may be completely opposite to that of the main channel, which makes the flow resistance of the branch channel significantly increase compared to other branch channels, resulting in uneven final flow rates of each branch in the same time period.

[0054] Therefore, this application proposes a flow channel component, a flow supply assembly, a cleaning device, and a cleaning system, aiming to solve, to some extent, the technical problem of uneven flow distribution in flow channel components of related technologies.

[0055] The specific technical solutions of this application will be described in detail below with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all drawings including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0056] Please see Figure 1 and Figure 2 According to a first aspect of this application, a flow channel 110 is provided, which has at least one branch flow channel 111. The branch flow channel 111 may be located inside the flow channel 110, or may be formed by the flow channel 110 being surrounded by surrounding environmental elements, and this application does not impose any limitations.

[0057] Please see Figure 2 The branch channel 111 includes a main channel 1111 and a first branch channel 1112 and a second branch channel 1113, which are respectively connected to the main channel 1111. The fluid flow directions of the first branch channel 1112 and the second branch channel 1113 are different. The fluid flow direction of the first branch channel 1112 has the same flow direction component as the fluid flow direction of the main channel 1111, while the fluid flow direction of the second branch channel 1113 has a flow direction component opposite to the fluid flow direction of the main channel 1111.

[0058] Due to the difference in flow direction, the first branch channel 1112 has relatively low flow resistance, resulting in higher flow velocity and flow rate, while the second branch channel 1113 has relatively high flow resistance, leading to lower flow velocity and flow rate. To address this, this application provides a flow guiding structure 112 at the connection between the second branch channel 1113 and the main channel 1111. The flow guiding structure 112 guides the fluid in the main channel 1111 to the second branch channel 1113, thereby actively guiding the flow direction of the fluid in the main channel 1111 through a mechanical structure. This eliminates the flow resistance difference between the first branch channel 1112 and the second branch channel 1113, ensuring that the fluid in the main channel 1111 is evenly distributed to the first branch channel 1112 and the second branch channel 1113, guaranteeing a uniform final flow rate in both branches within the same timeframe.

[0059] The first branch channel 1112 and the second branch channel 1113 can serve as intermediate channels in the water or air circuits within the cleaning equipment 1000, connecting the output components of the water or air circuits; the first branch channel 1112 and the second branch channel 1113 can also serve as output channels for the water or air circuits. In some embodiments, both the first branch channel 1112 and the second branch channel 1113 are provided with one or more supply ports 113 communicating with the outside. The supply port 113 can be an opening on the flow channel component 110, an outwardly protruding pipe joint, or an inwardly recessed mounting area. The specific structure of the supply port 113 is not limited in this application.

[0060] The connection point between the first branch channel 1112 and the main channel 1111, and the connection point between the second branch channel 1113 and the main channel 1111, can be located at different positions on the main channel 1111. In this case, in order to further balance the flow rates of the first branch channel 1112 and the second branch channel 1113, the connection point between the first branch channel 1112 and the main channel 1111 can be located downstream of the connection point between the second branch channel 1113 and the main channel 1111.

[0061] Please see Figure 3 and Figure 3A In some embodiments, the main channel 1111 is provided with a branch port 11111, and the first branch channel 1112 and the second branch channel 1113 are both connected to the main channel 1111 through the branch port 11111. That is, the branch port 11111 serves as the confluence point of the main channel 1111, the first branch channel 1112, and the second branch channel 1113, and the connection point between the first branch channel 1112 and the main channel 1111 is located at the same position as the connection point between the second branch channel 1113 and the main channel 1111.

[0062] In some embodiments, a notch may be provided on the flow channel wall of the main flow channel 1111, which forms a branch port 11111. The branch port 11111 has two opposing sidewalls. When the fluid in the branch channel flows into the first branch channel 1112 and the second branch channel 1113, it will come into contact with the two sidewalls of the branch port 11111. Therefore, the walls of the two sidewalls have a certain guiding effect on the fluid.

[0063] In some embodiments, the flow guiding structure 112 includes a flow guiding slope 1121 disposed on at least one sidewall of the branch port 11111. The flow guiding slope 1121 is inclined relative to the fluid flow direction of the main channel 1111, and the flow guiding slope 1121 has a projection component opposite to the fluid flow direction of the main channel 1111. In other words, the guide slope 1121 is inclined toward the direction of the second branch channel 1113. Thus, after the fluid comes into contact with the guide slope 1121, the guide slope 1121 applies a force to the fluid toward the direction of the second branch channel 1113, actively guiding the flow of the fluid in the branch port 11111 toward the second branch channel 1113. Since the first branch channel 1112 has a flow direction that is approximately the same as that of the main channel 1111, the fluid will also smoothly enter the first branch channel 1112 even without the guide structure 112, thereby ensuring that the final flow rate of the first branch channel 1112 and the second branch channel 1113 is uniform in the same time.

[0064] Please see Figure 4 and Figure 4A In the diversion port 11111, one of the two sidewalls is further away from the inlet 11113 of the main channel 1111 than the other sidewall. For ease of understanding, the sidewall closer to the inlet 11113 of the main channel 1111 is denoted as C, and the sidewall further away from the inlet 11113 of the main channel 1111 is denoted as D. Therefore, the fluid in the main channel 1111 exerts a greater impact force on sidewall D, and correspondingly, the guiding slope 1121 on sidewall D has a better guiding effect on the fluid. Therefore, it is permissible to provide a guiding slope 1121 on at least sidewall D of the diversion port 11111. Of course, in some embodiments, both sidewalls C and D of the diversion port 11111 may be provided with guiding slopes 1121. The inclination angle of the guide slope 1121 can be adjusted according to factors such as the length of the branch channel path and the size of the inlet 113 in the actual situation, so as to ensure that the final flow rate of the first branch channel 1112 and the second branch channel 1113 is uniform in the same time.

[0065] Please see Figure 4A In some embodiments, the axial direction of the diversion port 11111 (e.g.) Figure 4A (as shown by line d) and the fluid flow direction of the main channel 1111 (as shown by line d) Figure 4AThe included angle α between the two points (indicated by the middle arrow a) is 45° ≤ α < 90°. Because the angle between the branch outlet 11111 and the main channel 1111 is relatively large, please refer to [reference needed] for further reduction of flow resistance. Figure 5 and Figure 5A In some embodiments, the flow guiding structure 112 further includes a flow guiding surface 1122 disposed on the inner wall of the main flow channel 1111. The flow guiding surface 1122 is tangent to the flow guiding slope 1121 of the side wall D. By disposing of the flow guiding surface 1122, it can be ensured that the fluid in the main flow channel 1111 can smoothly enter the branch port 11111.

[0066] The entrance 11113 of the main road 1111 is usually located at the beginning A of the main road 1111. Please refer to [link / reference]. Figure 4 and Figure 5 In some embodiments, the diversion port 11111 and the tail end B of the main channel 1111 are spaced apart, and the portion between the tail end B of the main channel 1111 and the diversion port 11111 forms a buffer zone 11112, such as... Figure 4A As shown. The buffer zone 11112 can temporarily store a certain volume of fluid, serving as a buffer area before the fluid enters the diversion port 11111, thereby reducing the flow resistance when the fluid enters the diversion port 11111.

[0067] The flow channel wall containing the guide surface 1122 occupies a portion of the space in the main flow channel 1111, causing the depth of the buffer zone 11112 to be less than the depth of other areas of the main flow channel 1111. (See also...) Figure 3A In some embodiments, the guide surface 1122 is located above the buffer zone 11112 along the depth direction of the main channel 1111. When the fluid in the main channel 1111 is not completely filled, the fluid converges below the main channel 1111 under the action of gravity. By setting the buffer zone 11112 lower, it can be ensured that the buffer zone 11112 can always play a buffering role.

[0068] Please see Figure 3A and Figure 4A In some embodiments, the flow guiding structure 112 further includes a throttling valve point 1123 located at the boundary between the first branch channel 1112 and the second branch channel 1113. Specifically, the throttling valve point 1123 is located on the inner wall of the channel directly opposite the branch port 11111. The throttling valve point 1123 is a protruding structure extending towards the branch port 11111, and it has a tip 11231, which is the part of the protruding structure closest to the branch port 11111. When the fluid flowing out of the branch port 11111 encounters the tip 11231, it is split into two streams, which flow to the first branch channel 1112 and the second branch channel 1113 respectively.

[0069] Please see Figure 4AIn some embodiments, the tip 11231 is eccentrically positioned relative to the axis of the branch port 11111, specifically, the tip 11231 is closer to the first branch channel 1112 relative to the axis of the branch port 11111. Because the tip 11231 is closer to the first branch channel 1112, the distance between the throttling valve point 1123 and the opposite sidewall of the first branch channel 1112 is smaller than the distance between the throttling valve point 1123 and the opposite sidewall of the second branch channel 1113. This is equivalent to the inlet size of the first branch channel 1112 being smaller than the inlet size of the second branch channel 1113, thereby further compensating for the flow difference caused by the difference in flow direction between the first branch channel 1112 and the second branch channel 1113. The position and size of the throttling valve point 1123 can be adjusted according to factors such as the length of the branch channel path and the size of the supply port 113 in actual circumstances, ensuring that the final flow rate of the first branch channel 1112 and the second branch channel 1113 is uniform within the same time period.

[0070] To further reduce the flow resistance at the inlet 11113 of the first branch channel 1112 and the inlet 11113 of the second branch channel 1113, please refer to [link / reference needed]. Figure 4A In some embodiments, the throttle valve point 1123 is provided with two guide surfaces 11232 that are inclined relative to the axis d of the diversion port 11111. The two guide surfaces 11232 intersect to form a tip 11231, and the entire throttle valve point 1123 is approximately triangular.

[0071] In some embodiments, the two guide surfaces 11232 have different inclination angles. For example, the inclination angle of the guide surface 11232 facing the second branch channel 1113 is greater than the inclination angle of the guide surface 11232 facing the first branch channel 1112, so that the flow resistance at the inlet of the second branch channel 1113 is less than the flow resistance at the inlet of the first branch channel 1112. The guide surface 11232 can be a plane or a curved surface; this application is not limited to this. Please refer to... Figure 4A In some embodiments, both guide surfaces 11232 are concave arc surfaces, and the two guide surfaces 11232 are tangent to the inner walls of the first branch channel 1112 and the second branch channel 1113, respectively, forming a guide structure with a circular arc transition.

[0072] It is understood that the flow guiding structure 112 of the flow channel component 110 may simultaneously include at least one of the above-mentioned flow guiding slope 1121, flow guiding curved surface 1122, and throttling valve point 1123.

[0073] Please see Figure 3A , Figure 4A and Figure 5A In some embodiments, the first branch channel 1112 and the second branch channel 1113 are parallel and collinear. The fluid flow direction of the first branch channel 1112 (e.g., Figure 4A(As shown by arrow b) and the fluid flow direction of the main channel 1111 (as shown by arrow b) Figure 4A The fluid flow direction of the second branch channel 1113 (as shown by the middle arrow a) is the same (it can be basically parallel, for example, the included angle does not exceed 5°; it can also be parallel and collinear); Figure 4A (As indicated by arrow c) The fluid flow direction of the first branch channel 1112 and the second branch channel 1113 is opposite to that of the main channel 1111 (it can be substantially opposite, for example, the included angle is between 175° and 180°). That is, the direction of the first branch channel 1112 and the second branch channel 1113 can be substantially consistent with the main channel 1111, or the direction of the first branch channel 1112 and the second branch channel 1113 can be substantially opposite to that of the main channel 1111. In some embodiments, the first branch channel 1112 and the second branch channel 1113 can be a single channel, divided into the first branch channel 1112 and the second branch channel 1113 by the throttling valve point 1123.

[0074] Please see Figure 3A , Figure 4A and Figure 5A In some embodiments, the first branch channel 1112 is arranged side-by-side with the main channel 1111, and the second branch channel 1113 is also arranged side-by-side with the main channel 1111. The direction of the side-by-side arrangement is perpendicular to the extension direction of the main channel 1111, thereby maximizing the length of the flow channels and expanding the fluid supply area within a limited space. Of course, in other embodiments, when the installation space is relatively ample, the first branch channel 1112 and the second branch channel 1113 can also be arranged at an angle to the main channel 1111, thereby avoiding a 180° change in flow direction.

[0075] The flow channel component 110 can be an independent flow channel plate; it can also be integrated with the equipment that configures the flow channel plate, i.e., the equipment has multiple flow channels, and the component containing these multiple flow channels constitutes the flow channel component 110, and these multiple flow channels constitute the branch flow channel 111. In some embodiments, the flow channel component 110 is an independent part, and the flow channel component 110 is a rigid structure. It is understood that a rigid structure refers to a structure that can maintain its shape and size without significant deformation when subjected to force. The flow channel component 110 is made of rigid materials, such as plastic, carbon fiber, metal, glass, ceramics, etc. In contrast, flexible structures will undergo significant deformation when subjected to force, such as soft plastic tubes like silicone hoses or rubber hoses, or plastic tubes like straws.

[0076] When the flow channel component 110 is an independent part, it can be a one-piece structure, formed by injection molding, machining, 3D printing, etc. Alternatively, the flow channel component 110 can be a modular structure, comprising multiple sub-components sealed together to form multiple flow channels. Using a modular structure reduces the manufacturing difficulty of the flow channel component 110 and allows for the formation of flow channels with multiple curved structures.

[0077] Please see Figure 6 The diagram shows a cross-sectional view of the flow channel component 110 in some embodiments. The flow channel component 110 includes a first sub-component 114 and a second sub-component 115. At least one of the first sub-component 114 and the second sub-component 115 is provided with a groove, and the first sub-component 114 and the second sub-component 115 are sealed together to enclose the groove to form a flow channel 111. As one embodiment, a guide surface 1122 may be provided on the second sub-component 115, and a buffer zone 11112 may be provided on the first sub-component 114, that is, the first sub-component 114 is installed below the second sub-component 115. A guide ramp 1121 may be provided on the first sub-component 114 and / or the second sub-component 115. A throttling valve point 1123 may be provided on the first sub-component 114.

[0078] In some embodiments, only one of the first component 114 and the second component 115 may be provided with a groove, while the other is a cover plate. For example, the first component 114 may have three grooves, and the second component 115 may be a cover plate that covers the first component 114 and is sealed to it, thereby forming a main channel 1111, a first branch channel 1112, and a second branch channel 1113, respectively, through the three grooves. This scheme divides the first component 114 and the second component 115 along the depth of the grooves.

[0079] In other embodiments, both the first component 114 and the second component 115 may be provided with grooves. For example, both the first component 114 and the second component 115 may be provided with three grooves. The three grooves in the first component 114 and the second component 115 have the same shape, length, and distribution position. After the first component 114 and the second component 115 are fastened and sealed together with their groove openings facing each other, the three grooves respectively form the main flow channel 1111, the first branch flow channel 1112, and the second branch flow channel 1113. This scheme also divides the first component 114 and the second component 115 along the depth of the grooves.

[0080] When the groove is divided in half along its depth into a first component 114 and a second component 115, the depth of the groove in the first component 114 is the same as the depth of the groove in the second component 115. In some embodiments, the depth of the groove in the first component 114 is greater than the depth of the groove in the second component 115, and the inlet 113 is located on the first component 114. That is, when the flow channel component 110 is installed, the first component 114 faces downward, and the liquid discharged from the inlet 113 can be smoothly discharged under the action of liquid pressure and its own weight. The greater depth of the groove in the first component 114 ensures that even if leakage occurs at the connection between the first component 114 and the second component 115, the leakage amount can be reduced because the leakage point is relatively high.

[0081] In some other embodiments, both the first component 114 and the second component 115 may be provided with grooves. For example, both the first component 114 and the second component 115 may be provided with inner partitions, thereby forming grooves of different widths on the first component 114 and the second component 115. The inner partitions of the first component 114 and the second component 115 are staggered. After the first component 114 and the second component 115 are fastened and sealed together with their grooves facing each other, the staggered inner partitions form the main flow channel 1111, the first branch flow channel 1112, and the second branch flow channel 1113. This scheme divides the first component 114 and the second component 115 along the width of the groove.

[0082] It is understandable that the flow channel component 110 can also be composed of three, four, or more sub-components. Further sub-component schemes for the flow channel component 110 will not be exhaustively listed here.

[0083] The sealing connection between the various components of the flow channel component 110 can be achieved by adhesive bonding, welding (e.g., ultrasonic welding), hot melting, or by fastening or clamping the sealing ring with fasteners. This application does not limit the specific sealing method.

[0084] Please see Figure 6 and Figure 6A The diagram shows a cross-sectional view of the flow channel component 110 and an enlarged view of the sealing connection in some embodiments. The mating surfaces of the first component 114 and the second component 115 of the flow channel component 110 are provided with a tongue-and-groove sealing structure. For example, please refer to... Figure 6A In some embodiments, the mating surface of the first component 114 is provided with a sealing recess 1141, and the mating surface of the second component 115 is provided with a sealing protrusion 1151. During assembly, the sealing protrusion 1151 is embedded in the sealing recess 1141, and the sealing recess 1141 and the sealing protrusion 1151 are fixed together by adhesive or ultrasonic welding, thereby forming a labyrinthine sealing structure on the mating surfaces of the first component 114 and the second component 115, maintaining good sealing performance. Based on this, the sealing effect of the flow channel component 110 can be guaranteed without using the sealing element 500.

[0085] The flow channel component 110 can be provided with multiple branch flow channels 111, and the main flow channels 1111 of the multiple branch flow channels 111 are respectively connected to different fluid sources. The multiple branch flow channels 111 can be independent of each other; in some embodiments, the main flow channels 1111 of the multiple branch flow channels 111 can be interconnected; in other embodiments, the first branch flow channels 1112 of the multiple branch flow channels 111 can be interconnected; in still other embodiments, the second branch flow channels 1113 of the multiple branch flow channels 111 can be interconnected. The flow channel configuration inside the flow channel component 110 is not limited in this application.

[0086] Figure 3 In the embodiment shown, the flow channel 110 is provided with two independent branch flow channels 111. The main flow channel 1111 of the two branch flow channels 111 is centrally located, and the first branch flow channel 1112 and the second branch flow channel 1113 of the two branch flow channels 111 are respectively located on the two outer sides of the flow channel 110, so that the flow channel 110 has a larger flow supply area.

[0087] To ensure uniform fluid distribution in each branch channel, in some embodiments, the first branch channel 1112 and the second branch channel 1113 are connected to the main channel 1111 at the same location, and the flow path length from the inlet 113 of the first branch channel 1112 and the second branch channel 1113 to the connection point is the same. That is, the flow path length from each inlet 113 to the branch port 11111 is the same, and the liquid in the main channel 1111 can flow out uniformly from each inlet 113.

[0088] Please see Figure 7 According to a second aspect of this application, a flow supply component 100 is provided. The fluid supplied by the flow supply component 100 is a liquid, which may be at least one of water, cleaning agent, disinfectant, polishing agent, floor care agent, deodorizer, and fragrance essential oil. For example, the liquid stored in the flow storage component 130 is water, used to wet the mop 310 to achieve the function of wet mopping, or to wet the vacuum port to reduce floating dust; or, for example, the liquid stored in the flow storage component 130 is a mixture of floor care agent and water, used to wet the mop 310 to achieve the function of floor care after mopping. Therefore, the flow supply component 100 can be applied not only to cleaning equipment 1000 including sweeping robots, mopping robots, sweeping and mopping robots, floor scrubbers, etc., but also to other equipment with flow supply requirements, such as humidifiers and steam irons.

[0089] Please see Figure 7 The flow supply assembly 100 includes a flow storage component 130, a first power component 120, and a flow channel component 110 as described in the first aspect. The flow storage component 130 has a flow storage cavity 131 for storing liquid. The first power component 120 is connected to both the flow storage cavity 131 and the branch flow channel 111 of the flow channel component 110, driving the liquid in the flow storage cavity 131 to flow into the branch flow channel 111 of the flow channel component 110. The liquid stored in the flow storage component 130 is discharged through the flow channel component 110, thus supplying liquid to external components.

[0090] Please see Figure 8 , Figure 9 and Figure 10The diagrams show schematic and cross-sectional views of the storage component 130 from different perspectives. The storage component 130 includes a storage cavity 131 and an injection port 132 communicating with the storage cavity 131. The storage cavity 131 is used to contain liquid, and the liquid contained in the storage cavity 131 can flow out through the injection port 132. The storage component 130 can be an independent water tank; the storage component 130 can also be integrated with the equipment that configures the flow supply assembly 100, i.e., the equipment has an internal cavity that can contain liquid, in which case the component containing the cavity constitutes the storage component 130, and the cavity constitutes the storage cavity 131.

[0091] The injection port 132 can be located at any position on the storage component 130. For example, if the storage component 130 is a cylindrical water tank, the injection port 132 can be located on the cylindrical side, top, or bottom surface of the cylindrical water tank. In some embodiments, the injection port 132 is located at the lower part of the storage component 130, which can be the lower part of the side of the storage component 130 or the bottom surface of the storage component 130. This allows gravity to assist in liquid discharge and enables the liquid in the storage cavity 131 to be drained as completely as possible. The injection port 132 can be an opening on the storage component 130, an outwardly protruding pipe joint, or an inwardly recessed installation area. The specific structure and installation position of the injection port 132 are not limited in this application.

[0092] The first power component 120 is provided with a liquid extraction port (not visible in the figure) and a liquid outlet (not visible in the figure) to provide power for the flow of liquid. The first power component 120 can be a water pump, an electric telescopic cylinder, etc., and this application is not limited thereto. The liquid extraction port and the liquid outlet can be openings made on the first power component 120, or they can be outwardly protruding pipe joints or inwardly recessed mounting areas. This application is not limited in the specific structure of the liquid extraction port and the liquid outlet.

[0093] Please see Figure 10 In some embodiments, the storage device 130 is further provided with an injection port 132 that communicates with the storage cavity 131. The extraction port of the first power device 120 is connected to the injection port 132 of the storage device 130 through the extraction pipe 140. The outlet of the first power device 120 is connected to the main channel 1111 of the flow channel device 110 through the outlet pipe 150.

[0094] Please see Figure 10In some embodiments, the storage component 130 is further provided with an overflow port 133 communicating with the storage cavity 131, and the flow channel component 110 is provided with two branch flow channels 111, which are respectively connected to the injection port 132 and the overflow port 133. Specifically, the branch flow channel 111 connected to the injection port 132 is the injection flow channel 111a, and the branch flow channel 111 connected to the overflow port 133 is the overflow flow channel 111b. The overflow port 133 of the storage component 130 is connected to the main flow channel 1111 of the overflow flow channel 111b through the overflow pipe 160. The outlet of the first power component 120 is connected to the main flow channel 1111 of the injection flow channel 111a through the outlet pipe 150. The injection flow channel 111a and the overflow flow channel 111b are independent of each other.

[0095] By setting the overflow port 133, on the one hand, when the liquid level in the storage cavity 131 exceeds the position of the overflow port 133, the excess liquid will flow out from the overflow port 133 and flow to the overflow channel 111b, thus avoiding excessive liquid in the storage cavity 131, which would increase the water pressure and cause the storage device 130 to open or break unexpectedly; on the other hand, during the process of replenishing liquid to the storage device 130, the air in the storage cavity 131 can be discharged through the overflow port 133 to maintain the air pressure balance in the storage cavity 131, so that the liquid can smoothly enter the storage cavity 131.

[0096] The overflow channel 111b can temporarily store liquid overflowing from the flow cavity 131, or it can discharge liquid overflowing from the storage cavity 131 to the outside of the flow channel component 110. In some embodiments, the injection channel 111a and the overflow channel 111b are connected, and the main channel 1111 of the injection channel 111a and the main channel 1111 of the overflow channel 111b can be integrated into one unit and located in the central region of the flow channel component 110. This can save one main channel 1111 and reduce the volume of the flow channel component 110. In still some embodiments, the flow channel component 110 may have only one branch channel 111, and both the injection port 132 and the overflow port 133 are connected to the main channel 1111 of the branch channel 111.

[0097] Please see Figure 11 According to a third aspect of this application, a flow supply component 100 is provided. The fluid supplied by the flow supply component 100 is gas, and the airflow in the flow channel component 110 can be a suction airflow or a blowing airflow. Therefore, the flow supply component 100 can be applied not only to cleaning equipment 1000 including robotic vacuum cleaners, robotic vacuum and mop, vacuum cleaners, etc., but also to other equipment with flow supply requirements, such as dryers.

[0098] Please see Figure 11The flow supply assembly 100 includes a second power component and the flow channel component 110 described in the first aspect. The second power component is connected to the flow channel 111 of the flow channel component 110, providing power for the flow of air. The second power component can be an air pump, an electric telescopic cylinder, etc., and this application does not impose any restrictions.

[0099] Please see Figure 12 According to a fourth aspect of this application, a cleaning device 1000 is provided. The cleaning device 1000 includes a device body 200 and a flow supply component 100 of any of the embodiments of the second or third aspect described above. The flow supply component 100 is connected to the device body 200. The cleaning device 1000 may be a sweeping robot, a mopping robot, a sweeping and mopping robot, a floor scrubber, a vacuum cleaner, etc., and this application does not impose any limitations.

[0100] Please see Figure 12 In some embodiments, the cleaning device 1000 has a wet floor cleaning function and is equipped with a supply component 100 according to any of the embodiments of the second aspect described above. The cleaning device 1000 also includes a cleaning component 300 connected to the device body 200. The cleaning component 300 can be installed at the bottom of the device body 200 and contacts the surface to be cleaned. The cleaning component 300 can be at least one of a mop 310, a sponge, a roller brush 320, a side brush 330, etc. The supply component 100 is connected to the device body 200. The supply component 100 can be entirely installed inside the device body 200; alternatively, only some components can be installed inside the device body 200, for example, the liquid storage component 130 may be exposed relative to the device body 200, allowing the user to directly add liquid to the liquid storage component 130.

[0101] In some embodiments, the flow channel 110 of the flow supply assembly 100 is provided with a flow port 113, which corresponds to the position of the cleaning component 300 to provide fluid to the cleaning component 300. The correspondence between the flow port 113 and the cleaning component 300 can be such that the flow port 113 is located above the cleaning component 300, or that the cleaning component 300 is located in the path of the liquid supplied by the flow port 113. In short, it is sufficient to ensure that the liquid supplied by the flow port 113 contacts the cleaning component 300. In other embodiments, the flow port 113 of the flow supply assembly 100 can also be positioned to correspond to the position of the suction port or suction pipe of the cleaning device 1000, enabling the spraying of liquid into the suction port or suction pipe to achieve the function of dust suppression through spraying.

[0102] Please see Figure 13 and Figure 14The diagrams show the connection structure of the flow supply component 100 and the device body 200 in certain embodiments of the cleaning device 1000 from different perspectives. The flow supply component 100's storage element 130, flow channel element 110, and first power element 120 are sequentially distributed along the circumference of the device body 200. The storage element 130, flow channel element 110, and first power element 120 are connected to the bottom shell 210 of the device body 200 by fasteners, facilitating installation and disassembly. In some embodiments, the flow channel element 110 is located close to the outer periphery of the device body 200, and its shape can be adaptively designed according to the device body 200. Taking a common circular cleaning robot as an example, where the device body 200 is cylindrical, the flow channel element 110 has a certain curvature.

[0103] Since the flow channel component 110 has a flat flow channel plate structure and a low height, please refer to [reference needed]. Figure 13 In some embodiments, the first power member 120 is stacked above the flow channel member 110. Firstly, this saves circumferential space in the main body 200; secondly, it further shortens the length of the liquid extraction pipe 140 and the liquid outlet pipe 150; and thirdly, it reduces the contact area between the first power member 120 and the main body 200, thereby reducing vibration noise transmitted from the first power member 120 to the main body 200. In some embodiments, a shock-absorbing pad may also be provided between the first power member 120 and the flow channel member 110.

[0104] Please see Figure 14 In some embodiments, the bottom shell 210 of the device body 200 has one or more through holes 211. The number and distribution of the through holes 211 are exactly the same as the flow inlets 113 of the flow channel component 110, and each flow inlet 113 corresponds one-to-one with each through hole 211. The flow inlet 113 can be an opening provided on the flow channel component 110, which is positioned opposite to the through hole 211 to achieve communication. Please refer to [link to relevant documentation]. Figure 14 In some embodiments, the supply port 113 is a plurality of protruding liquid outlets provided on the flow channel 110, and the liquid outlets extend into the corresponding through holes 211, which are closer to the cleaning component 300.

[0105] Please see Figure 14 In some embodiments, a seal 500 is provided between the flow channel 110 and the bottom shell 210. The seal 500 surrounds the outer periphery of the inlet 113 and the through hole 211 to ensure sealing and prevent liquid leakage into the interior of the device body 200. The seal 500 can be a rubber gasket or a silicone gasket, and this application is not limited thereto.

[0106] Please see Figure 13In some embodiments, the bottom shell 210 is provided with a recessed mounting groove 212, the shape and size of which are adapted to the flow channel component 110. The flow channel component 110 is embedded in the mounting groove 212, and each through hole 211 is provided at the bottom of the mounting groove 212. The flow channel component 110 is embedded in the mounting groove 212, which on the one hand reduces the height space occupied by the flow channel component 110, making it convenient to arrange other components (such as the first power component 120) above the flow channel component 110; on the other hand, the mounting groove 212 limits the flow channel component 110, so that the position of the flow channel component 110 and the bottom shell 210 is fixed, preventing the flow channel component 110 from moving and causing the pipe connected to it to become loose.

[0107] Please see Figure 13 In some embodiments, the cleaning device 1000 also has an automatic liquid replenishment function. The main body 200 of the device is provided with a liquid replenishment component 400, which is connected to the storage component 130 and can replenish liquid into the storage component 130 through the liquid replenishment component 400. The liquid replenishment component 400 can be a pipe interface, which is connected to the storage component 130 through a liquid replenishment pipe 410. This pipe interface can be connected to a faucet or a liquid replenishment nozzle of the cleaning base station 2000, thereby filling liquid into the storage cavity 131. In some embodiments, the liquid replenishment component 400, the storage component 130, the flow channel component 110, and the first power component 120 are all connected by soft rubber tubing, that is, the liquid injection pipe, the liquid outlet pipe 150, the overflow pipe 160, and the liquid replenishment pipe 410 are all soft rubber tubing.

[0108] Please see Figure 12 In some embodiments, the cleaning device 1000 is a sweeping and mopping machine, and the cleaning component 300 includes a mop 310 and a roller brush 320, with the inlet 113 corresponding to the position of the mop 310. Please refer to [link / reference]. Figure 13 In some embodiments, the main body 200 of the device is provided with a dust collection chamber 220 and a dust outlet channel 230 communicating with the dust collection chamber 220. The installation area 240 of the roller brush 320 is communicating with the dust collection chamber 220. The dust outlet channel 230 is located between the storage component 130 and the first power component 120, making full use of the area between the storage component 130 and the first power component 120, so that the cleaning device 1000 is more compact inside and smaller in overall size.

[0109] Please see Figure 15 According to a fifth aspect of this application, a cleaning system is provided, including a base station 2000 and a cleaning device 1000 according to any of the embodiments of the fourth aspect described above. The cleaning device 1000 can be docked with or detached from the base station 2000.

[0110] Please see Figure 16 and Figure 17In some embodiments, the base station 2000 includes a base station body 2100 and a cleaning tank 2200 installed in the base station body 2100. When the cleaning equipment 1000 enters the base station body 2100, the mop 310 of the cleaning equipment 1000 is located in the cleaning tank 2200, and the mop 310 is cleaned by the liquid in the cleaning tank 2200.

[0111] In some embodiments, the base station 2000 can not only clean the mop 310 of the cleaning device 1000, but also have at least one of the following functions: charging the cleaning device 1000, drying the mop 310 of the cleaning device 1000, adding cleaning liquid to the cleaning device 1000, and collecting garbage in the dust collection chamber 220 of the cleaning device 1000.

[0112] As one implementation, the base station 2000 may further include a power supply module (not shown in the figure), which is connected to the base station body 2100. The power supply module of the base station 2000 may be a battery capable of storing electrical energy; the battery may be a rechargeable battery or a primary battery, allowing the base station 2000 to be charged or the battery replaced periodically. The power supply module may also include a transformer charger, capable of converting external power into power that the cleaning device 1000 can input, and then conducting it to the charging component 600 of the cleaning device 1000. The power supply module may also be a power cord, serving only a conductive function. The specific structure of the power supply module is not limited in this application.

[0113] Please see Figure 16 and Figure 17 To facilitate charging, in some embodiments, the cleaning device 1000 may further include a charging component 600 and a battery (not shown in the figure), with the charging component 600 electrically connected to the battery. When the power supply module of the base station 2000 is also a battery, the capacity of the base station 2000's battery can be greater than the capacity of the cleaning device 1000's battery, allowing the base station 2000 to power the cleaning device 1000 multiple times on a single charge. Please refer to [link / reference]. Figure 17 When the cleaning equipment 1000 enters the base station body 2100, the power supply module 2300 is electrically connected to the charging component 600 of the cleaning equipment 1000, and the power supply module charges the battery of the cleaning equipment 1000 through the charging component 600.

[0114] Please see Figure 16As another implementation, the base station 2000 may further include a liquid injection module 2400, which is connected to the base station body 2100. The liquid injection module 2400 includes an injection component and an injection nozzle on the equipment body 200. The injection nozzle connects to a replenishment component 400 on the cleaning equipment 1000 to replenish the cleaning liquid in the storage component 130 of the cleaning equipment 1000. When the cleaning equipment 1000 enters the base station body 2100, the liquid injection module 2400 communicates with the replenishment component 400 of the cleaning equipment 1000 to replenish the cleaning liquid in the storage component 130 of the cleaning equipment 1000.

[0115] As another implementation, the base station 2000 may also include a drying module (not shown in the figure), which is connected to the base station body 2100. The drying module includes a fan and a heating element. The fan blows hot air generated by the heating element outward, thereby drying the cleaned mop 310. The mop 310 can be located in or outside the cleaning tank 2200 during drying. When the cleaning equipment 1000 enters the base station body 2100, the mop 310 is first cleaned through the cleaning tank 2200. After the mop 310 is cleaned, the drying module provides hot airflow to the mop 310 to dry it.

[0116] Please see Figure 16 As another implementation, the base station 2000 may further include a dust collection module 2500, which is connected to the base station body 2100. The dust collection module 2500 includes a dust bag and a dust collection channel communicating with the dust bag. The debris swept by the roller brush 320 and side brush 330 of the cleaning equipment 1000 enters the dust collection chamber 220 of the cleaning equipment 1000. When the cleaning equipment 1000 enters the base station body 2100, the dust collection channel of the base station 2000 communicates with the dust outlet channel 230 of the cleaning equipment 1000 to draw dust and debris from the dust collection chamber 220 of the cleaning equipment 1000 into the dust bag.

[0117] It is understood that the base station 2000 may be configured with at least one of the aforementioned cleaning tank 2200, power supply module, liquid injection module 2400, drying module, and dust collection module 2500. Other undescribed structures of the base station 2000 and cleaning equipment 1000 of the cleaning system can be found in the relevant disclosures of the prior art, and this application does not impose any limitations.

[0118] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0119] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0120] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
