Abstract
Description
Technical Field
[0001] This application relates to the field of electrical technology, and in particular to a four-way connector, a drainage system, a cleaning device, and a cleaning system. Background Technology
[0002] With the development of smart homes, various cleaning devices have been widely used in households, alleviating people's cleaning burden. In related technologies, cleaning devices include multiple cleaning modules with different cleaning functions. Each module has its own sewage discharge requirement and is equipped with its own sewage discharge pipe. To achieve unified sewage discharge management, multiple T-joints are generally used to connect the sewage discharge pipes of each module to the main sewage discharge pipe. However, setting multiple T-joints not only increases the complexity of the piping system but also occupies a large installation space, which is detrimental to the internal spatial layout of the cleaning device.

[0005] The four-way connector provided in this application embodiment can connect and merge four pipelines by setting a main pipe and connecting a first branch pipe and a second branch pipe to the main pipe. By setting a partition inside the main pipe to separate the first port of the main pipe and the third port for connecting the branch pipes, it can prevent the fluid in the main pipe from flowing back into the branch pipes and prevent whistling when the fluid flows through the third port. This four-way connector can be applied to drainage systems and cleaning equipment. A single four-way connector can replace multiple traditional connectors to realize complex pipeline connections, thereby reducing the assembly difficulty of pipeline connections, saving assembly space, and optimizing the drainage and noise performance of the product.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0042] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.
[0043] In related technologies, cleaning equipment includes a laundry cleaning module and a base station module. The laundry cleaning module is used to wash or dry clothes, while the base station module houses floor cleaning devices such as sweepers. The laundry cleaning module requires wastewater discharge during operation and is equipped with an independent wastewater discharge pipeline. The base station module requires both wastewater discharge and water replenishment during operation and is equipped with independent wastewater discharge pipelines and overflow protection pipelines. To achieve unified wastewater management, existing technologies generally use multiple T-joints to connect the wastewater discharge pipelines and overflow protection pipelines of each module to the main wastewater discharge pipe. However, this approach has significant drawbacks. First, the design of multiple T-joints increases the complexity of the piping system, and too many connection points may introduce sealing risks, affecting the reliability of the cleaning equipment's drainage system. Second, multiple T-joints occupy a large installation space, hindering the optimal layout of the equipment's internal space and reducing the integration of the cleaning equipment.
[0044] Currently, four-way connectors can be used to replace multiple three-way connectors to connect pipelines. However, existing four-way connectors have shortcomings. During use, they cannot achieve sewage isolation between multiple modules. This can cause whistling noises when each module operates independently due to different sewage discharge needs, which can affect the noise level of the cleaning equipment and thus the user experience.
[0045] Based on the above problems, this application provides a four-way connector, a drainage system, a cleaning device, and a cleaning system, aiming to optimize the drainage pipe connection structure within the cleaning device and improve the structural rationality and product performance of the cleaning device.
[0046] Please refer to Figures 1-4 An embodiment of the first aspect of this application provides a four-way connector 1, including a main pipe 11, a first branch pipe 12, and a second branch pipe 13. Please refer to... Figure 1 and Figure 2 The main pipe 11 includes a first port 111, a second port 112, and a third port 113. The main pipe 11 has an internal partition 114 that separates the first port 111 and the third port 113. A first branch pipe 12 is connected to the main pipe 11 and communicates with the third port 113. A second branch pipe 13 is connected to the main pipe 11 and communicates with the third port 113.
[0047] Main pipe 11 refers to the main pipe of the four-way connector 1. Main pipe 11 can be of various shapes and sizes. For example, main pipe 11 can be cylindrical or prismatic. The cross-sectional shape of the channel inside main pipe 11 can be circular, semi-circular, square or other irregular shapes. Main pipe 11 can also be a straight pipe or a curved pipe. Main pipe 11 can be made of various materials, such as plastic or corrosion-resistant metal.
[0048] The first port 111 is located at one end of the main pipe 11 and can be used to connect the sewage pipe of the independent cleaning module and serve as a sewage inlet; the second port 112 is located at the other end of the main pipe 11 and can be used to connect the main sewage pipe and serve as a sewage outlet; the first port 111 and the second port 112 are connected, and a sewage flow channel is formed between the first port 111 and the second port 112; the third port 113 is located on the pipe wall of the main pipe 11 and can be used to connect the branch pipe so that the branch pipe is connected to the channel in the main pipe 11.
[0049] The dividing section 114 refers to a solid water-blocking rib structure disposed within the main pipe 11. In any case, the dividing section 114 and the pipe wall of the main pipe 11 can be an integral structure, or they can be separate structures assembled together by snap-fit, adhesive, or other methods. The dividing section 114 separates the first port 111 and the third port 113. This separation can be understood as the first port 111 and the third port 113 not being directly connected, and the fluid flow path from the first port 111 to the second port 112 does not pass through the third port 113. Understandably, in some cases, the dividing section 114 extends along the length of the main pipe 11, and can separate independent first channels 115 and second channels 116 within the main pipe 11. The first channels 115 and second channels 116 are used to form independent sewage discharge paths; wherein, the first channel 115 serves as the main channel within the main pipe 11 for sewage discharge, and the second channel 116 serves as a branch channel within the main pipe 11 for sewage discharge from the first branch pipe 12 and the second branch pipe 13.
[0050] The first branch pipe 12 refers to the branch pipe connected to the main pipe 11. The first branch pipe 12 can be of various shapes and sizes. For example, the first branch pipe 12 can be cylindrical or prismatic. The cross-sectional shape of the channel inside the first branch pipe 12 can be circular, semi-circular, square or other irregular shapes. The first branch pipe 12 can also be a straight pipe or a curved pipe. The first branch pipe 12 can be made of various materials, such as plastic or corrosion-resistant metal.
[0051] The second branch pipe 13 refers to a branch pipe installed on the main pipe 11. The second branch pipe 13 can be of various shapes and sizes. For example, the second branch pipe 13 can be cylindrical or prismatic. The cross-sectional shape of the channel inside the second branch pipe 13 can be circular, semi-circular, square or other irregular shapes. The second branch pipe 13 can also be a straight pipe or a curved pipe. The second branch pipe 13 can be made of various materials, such as plastic or corrosion-resistant metal.
[0052] The four-way connector 1 provided in the above embodiment, by setting a main pipe 11 and connecting a first branch pipe 12 and a second branch pipe 13 to the main pipe 11, can realize the connection and convergence of four pipes. By setting a partition 114 inside the main pipe 11 to separate the first port 111 of the main pipe 11 and the third port 113 used to connect the branch pipes, it can prevent the fluid in the main pipe 11 from flowing back into the branch pipes and prevent the whistling when the fluid flows through the third port 113. The above-mentioned four-way connector 1 can be applied to drainage systems and cleaning equipment 1000. A single four-way connector 1 can replace multiple traditional connectors to realize complex pipe connections, thereby reducing the assembly difficulty of pipe connections, saving assembly space, and also optimizing the drainage and noise performance of the product.
[0053] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the edge of the partition 114 is connected to the inner wall of the main pipe 11, the third port 113 is located between the first port 111 and the second port 112, one end of the partition 114 is flush with the second port 112, and the other end of the partition 114 is located between the first port 111 and the third port 113.
[0054] A first channel 115 is formed between the first port 111 and the second port 112, and a second channel 116 is formed between the third port 113 and the second port 112. The cross-sectional dimensions of the first channel 115 and the second channel 116 can be designed according to the actual situation. For example, in some cases, the four-way connector 1 is used in the cleaning equipment 1000, wherein the first channel 115 is used for drainage of the clothes cleaning module 100, and the second channel 116 is used for drainage of the base station module 200. The drainage requirement of the clothes cleaning module 100 is greater than that of the base station module 200, so the cross-sectional dimension of the first channel 115 is required to be no less than the cross-sectional dimension of the second channel 116.
[0055] In the above embodiments, by reasonably designing the partition 114, the spacing effect between the first port 111 and the third port 113 can be improved, thereby effectively reducing the mutual interference between the fluid flowing into the first port 111 and the fluid flowing into the third port 113, and further reducing the risk of whistling.
[0056] Please refer to Figure 1 and Figure 3 In some embodiments, the first branch pipe 12 is disposed on the main pipe 11, and the second branch pipe 13 is disposed on the first branch pipe 12.
[0057] The first branch pipe 12 and the main pipe 11 can be an integral structure, or they can be separate structures assembled together by means of threaded connection, welding, snap-fit, etc. The second branch pipe 13 and the first branch pipe 12 can be an integral structure, or they can be separate structures assembled together by means of threaded connection, welding, snap-fit, etc. As an example, the four-way connector 1 can be made of PVC (Polyvinyl Chloride) and integrally molded by injection molding process.
[0058] In the above embodiment, the first branch pipe 12 is directly connected to the main pipe 11, and the second branch pipe 13 is directly connected to the first branch pipe 12, forming a two-stage confluence structure. When the first branch pipe 12 and the second branch pipe 13 discharge sewage at the same time, they can first mix into the same flow direction before flowing into the main pipe 11. This helps to reduce the impact of fluids when they converge in the main pipe 11, and further reduce noise and vibration problems. At the same time, this structure reduces the number of openings on the main pipe 11 (that is, the joints formed when the branch pipes are connected to the main pipe 11), and also helps to improve the structural strength of the main pipe 11, thereby improving the reliability of the four-way connector 1.
[0059] Understandably, in some other embodiments, the first branch pipe 12 and the second branch pipe 13 can be respectively disposed on the main pipe 11. The first branch pipe 12 / second branch pipe 13 and the main pipe 11 can be an integral structure, or they can be separate structures and assembled together by means of threaded connection, welding, snap-fit, etc.
[0060] Please refer to Figure 1 and Figure 3 In some embodiments, the first branch pipe 12 is vertically disposed on the main pipe 11.
[0061] The perpendicular arrangement of the first branch pipe 12 and the main pipe 11 can be understood as follows: at the connection point, the axes of the first branch pipe 12 and the main pipe 11 are perpendicular. As an example, both the first branch pipe 12 and the main pipe 11 are straight pipes, and the extension directions of the first branch pipe 12 and the main pipe 11 are perpendicular.
[0062] In the above embodiments, the first branch pipe 12 and the main pipe 11 are arranged vertically, which can effectively utilize the space on the side of the main pipe 11 and reduce the space occupied by the four-way connector 1. In addition, in some cases, the four-way connector 1 is used in the cleaning equipment 1000, and the sewage pipe connected to the first branch pipe 12 can be designed with a vertically distributed layout structure with the main pipe 11. This is conducive to improving the rationality of the layout of the sewage pipe in the cleaning equipment 1000 and improving the integration and space utilization efficiency of the components in the cleaning equipment 1000.
[0063] Understandably, in some other embodiments, the first branch pipe 12 may be disposed at an angle on the main pipe 11.
[0064] Please refer to Figure 1 and Figure 3 In some embodiments, the second branch pipe 13 is inclinedly disposed on the first branch pipe 12.
[0065] The inclined arrangement of the second branch pipe 13 and the first branch pipe 12 can be understood as follows: at the connection point, the axes of the second branch pipe 13 and the first branch pipe 12 intersect and form an acute or obtuse angle. As an example, both the second branch pipe 13 and the first branch pipe 12 are straight pipes, and their extension directions are not perpendicular.
[0066] The angle between the axes of the second branch pipe 13 and the first branch pipe 12 at the connection point can be 30°, 45°, or 60°, but is not limited to these.
[0067] In the above embodiments, by connecting the first branch pipe 12 and the second branch pipe 13 at an angle, the resistance and impact of fluid convergence at the connection between the first branch pipe 12 and the second branch pipe 13 can be reduced, thereby helping to further reduce noise and vibration problems during use.
[0068] Understandably, in some other embodiments, the second branch pipe 13 may be vertically disposed on the second branch pipe 13 or the main pipe 11.
[0069] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the four-way connector 1 includes a mounting plate 14 disposed on the main pipe 11, the mounting plate 14 being used to connect external components.
[0070] Mounting plate 14 refers to the connection structure set on the four-way connector 1, mainly used to connect the four-way connector 1 to external components and to fix the position of the four-way connector 1. Mounting plate 14 can be of various shapes and sizes, for example, mounting plate 14 can be a square flat plate; mounting plate 14 and main pipe 11 can be an integral structure, or they can be separate structures and assembled together by fastener connection, welding, snap-fit, etc.
[0071] As an example, external components can be structures such as the back panel, top panel, and mounting bracket in the cleaning equipment 1000.
[0072] In the above embodiments, by setting the mounting plate 14, the connection and fixation between the four-way connector 1 and the external components can be realized, which is beneficial to improving the reliability of the four-way connector 1. At the same time, the mounting plate 14 is directly integrated on the four-way connector 1, which is also beneficial to reduce the number of fixing parts.
[0073] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the mounting plate 14 is disposed on the side of the main pipe 11 facing the first branch pipe 12 and is arranged in parallel with the main pipe 11, with the first branch pipe 12 passing through the mounting plate 14.
[0074] The mounting plate 14 is located on the side of the main pipe 11 facing the first branch pipe 12. This can be understood as follows: with the axis of the main pipe 11 as a reference, the mounting plate 14 and the first branch pipe 12 are located on the same side of the main pipe 11.
[0075] The parallel arrangement of the mounting plate 14 and the main pipe 11 can be understood as the mounting plate 14 and the main pipe 11 being arranged in parallel. As an example, the mounting plate 14 is a flat plate with a certain thickness, the main pipe 11 is a branch pipe, and the normal of the mounting plate 14 is perpendicular to the axis of the main pipe 11.
[0076] The first branch pipe 12 passing through the mounting plate 14 can be understood as follows: the mounting plate 14 is provided with an opening that matches the outer diameter of the first branch pipe 12, and the first branch pipe 12 passes through the opening and is connected to the main pipe 11.
[0077] Regardless of the specific type, the mounting plate 14 can be connected to the first branch pipe 12 and the main pipe 11 via structures such as connecting ribs to enhance the fixing strength of the mounting plate 14 on the main pipe 11.
[0078] In the above embodiments, the mounting plate 14 is located at the position of the main pipe 11 for assembling the first branch pipe 12, which is beneficial to improve the integration of the four-way connector 1, thereby reducing the overall volume and space occupation of the four-way connector 1; at the same time, the mounting plate 14 connects the first branch pipe 12 and the main pipe 11, and can also help fix the first branch pipe 12, thereby improving the overall strength of the four-way connector 1.
[0079] Please refer to Figure 2 and Figure 4 In some embodiments, along the extension direction of the main pipe 11, the first branch pipe 12 and the mounting plate 14 are located in the middle of the main pipe 11.
[0080] As an example, the main pipe 11 is a straight pipe, and the first branch pipe 12 and the mounting plate 14 are connected at the middle position along the length of the main pipe 11.
[0081] Mounting plate 14 is used to connect external components and can fix and support four-way connector 1. In the above embodiment, mounting plate 14 is located in the middle of main pipe 11, which is beneficial to improve the stress on four-way connector 1 and make the supporting force on both ends of main pipe 11 more uniform, thereby improving the fixing effect and reliability of four-way connector 1.
[0082] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the four-way connector 1 includes two mounting plates 14, which are spaced apart and form a clamping gap 141 between them.
[0083] As an example, the four-way connector 1 can be applied in a cleaning device 1000, which includes a housing 3, a back panel 31, and two mounting plates 14 that can be located on the inner and outer sides of the back panel 31 respectively, and the four-way connector 1 is fixed to the back panel 31 by clamping the back panel 31.
[0084] In the above embodiments, by setting the mounting plate 14 and improving the structure of the mounting plate 14, the difficulty of fixing the four-way connector 1 can be reduced and the assembly efficiency can be improved.
[0085] Please refer to Figure 1 and Figure 2 In some embodiments, the two mounting plates 14 are of different sizes, and in a direction perpendicular to the thickness of the mounting plate 14, the mounting plate 14 away from the main pipe 11 protrudes beyond the mounting plate 14 near the main pipe 11. For example, the top of the mounting plate 14 away from the main pipe 11 is higher than the top of the mounting plate 14 near the main pipe 11.
[0086] In some cases, the four-way connector 1 is used in the cleaning equipment 1000 and installed on the rear panel 31 of the cleaning equipment 1000 housing 3. The mounting plate 14 away from the main pipe 11 abuts against the inner side of the rear panel 31, and the mounting plate 14 closer to the main pipe 11 abuts against the outer side of the rear panel 31. The rear panel 31 is provided with a through hole for the first branch pipe 12 to pass through. For ease of installation, the size of the through hole on the rear panel 31 is generally large. After the four-way connector 1 is snapped onto the rear panel 31, there may be an assembly gap between the top of the mounting plate 14 closer to the main pipe 11 and the rear panel 31. By increasing the height of the inner mounting plate 14, this gap can be sealed, reducing the risk of water leakage at the assembly position.
[0087] Please refer to Figure 1 and Figure 4 In some embodiments, at least one mounting plate 14 is provided with mounting holes 142 for mounting fasteners.
[0088] The shape, number, and location of the mounting holes 142 can be varied. For example, the mounting holes 142 can be circular holes or U-shaped holes. There can be one, two, or more mounting holes 142, and the mounting holes 142 can be located in the middle or at the edge of the mounting plate 14. As an example, the four-way connector 1 includes two mounting plates 14, which are spaced apart on the side of the main pipe 11 near the first branch pipe 12. Two mounting holes 142 are provided on the mounting plate 14 near the main pipe 11. The mounting holes 142 are U-shaped holes with openings formed at the edge of the mounting plate 14.
[0089] Fasteners can be, but are not limited to, bolts and pins.
[0090] In the above embodiments, fasteners can be used to connect the mounting plate 14 to external components, thereby assisting in positioning the assembly position of the four-way connector 1 and improving the fixing effect of the four-way connector 1.
[0091] Please refer to Figure 1 and Figure 4 In some implementations, the outer walls of the main pipe 11, the first branch pipe 12, and the second branch pipe 13 can be provided with structures such as ribs to facilitate pipe connection.
