Detailed Implementation
[0055] 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.
[0056] 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.
[0057] In related technologies, cleaning equipment with automatic water replenishment and wet mopping functions typically requires multiple water circuits internally, including but not limited to water replenishment circuits and multiple liquid supply circuits. Some cleaning equipment also has a self-cleaning mop function, requiring a self-cleaning water circuit internally. In these cleaning equipment, the liquid storage unit, power unit, and several liquid supply ports are all connected by water pipes, resulting in a large number and length of water pipes. Using water pipes is costly, and the crisscrossing arrangement of multiple water pipes not only occupies a significant amount of internal installation space, but the messy arrangement of multiple water pipes also makes them prone to pressure or bending, leading to poor liquid flow or even pipe bursts, thus affecting the cleaning performance of the equipment.
[0058] Therefore, this application proposes a liquid supply component and a cleaning device, which aims to solve to some extent the technical problems of numerous water pipes, messy water pipe layout, and easy pipe compression in related cleaning devices.
[0059] 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.
[0060] Please see Figure 1 and Figure 2 According to a first aspect of this application, a liquid supply assembly 100 is provided, including a liquid storage component 110, a power component 120, and a flow channel component 130. The liquid storage component 110 and the power component 120 are connected through the flow channel component 130, and the liquid stored in the liquid storage component 110 is discharged through the flow channel component 130 to supply liquid to external parts. The liquid stored in the liquid storage component 110 can be at least one of water, cleaning agent, disinfectant, polishing agent, floor care agent, and fragrance essential oil. For example, the liquid stored in the liquid storage component 110 is water, used to wet the mop 211 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 liquid storage component 110 is a mixture of floor care agent and water, used to wet the mop 211 to achieve the function of floor care after mopping. Therefore, the liquid 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 liquid supply requirements, such as humidifiers, steam irons, etc.
[0061] Please see Figure 3 , Figure 4 and Figure 4AThe diagrams show schematic and cross-sectional views of the liquid storage component 110 from different perspectives. The liquid storage component 110 includes a liquid storage chamber 111 and an injection port 112 communicating with the liquid storage chamber 111. The liquid storage chamber 111 is used to contain liquid, and the liquid contained in the liquid storage chamber 111 can flow out through the injection port 112. The liquid storage component 110 can be an independent water tank; the liquid storage component 110 can also be integrated with the equipment that configures the liquid 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 liquid storage component 110, and the cavity constitutes the liquid storage chamber 111.
[0062] The injection port 112 can be located at any position on the liquid storage component 110. For example, if the liquid storage component 110 is a cylindrical water tank, the injection port 112 can be located on the cylindrical side, top, or bottom surface of the cylindrical water tank. In some embodiments, the injection port 112 is located at the lower part of the liquid storage component 110, which can be the lower part of the side of the liquid storage component 110 or the bottom surface of the liquid storage component 110. This allows gravity to assist in liquid discharge and can drain the liquid in the liquid storage cavity 111 as completely as possible. The injection port 112 can be an opening on the liquid storage component 110, an outwardly protruding pipe joint, or an inwardly recessed installation area. The specific structure and installation position of the injection port 112 are not limited in this application.
[0063] The power component 120 is provided with a liquid extraction port 121 and a liquid outlet 122 to provide power for the flow of liquid. The power component 120 can be a water pump, an air pump, an electric telescopic cylinder, etc., and this application is not limited thereto. The liquid extraction port 121 and the liquid outlet 122 can be openings made on the 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 121 and the liquid outlet 122.
[0064] The flow channel component 130 is a rigid structure. A rigid structure, as understood, is one that maintains its shape and size without significant deformation under stress. The flow channel component 130 is made of rigid materials, such as plastic, carbon fiber, metal, glass, or ceramic. In contrast, flexible structures undergo significant deformation under stress, such as silicone hoses, rubber hoses, or plastic tubes like straws.
[0065] Please see Figure 5 , Figure 6 and Figure 7The flow channel 130 is provided with a liquid extraction flow channel 132, a liquid injection flow channel 131, and one or more liquid supply ports 136 communicating with the outside. The liquid extraction flow channel 132 and the liquid injection flow channel 131 can be located inside the flow channel 130, or can be formed by the flow channel 130 being enclosed by surrounding environmental elements. The liquid injection port 112 of the liquid storage component 110 and the liquid extraction port 121 of the power component 120 are connected through the liquid extraction flow channel 132. The liquid extraction flow channel 132 of the flow channel 130 is used as a water pipe connecting the liquid storage component 110 and the power component 120 in the prior art, so that the power component 120 can extract the liquid from the liquid storage chamber 111 of the liquid storage component 110. It is understandable that the liquid storage device 110 and the power device 120 can be connected solely through the liquid extraction channel 132, or the liquid injection port 112 of the liquid storage device 110 and the liquid extraction port 121 of the power device 120 can be connected to the liquid extraction channel 132 via water pipes. Regardless of the solution, using the channel 130 to connect the liquid storage device 110 and the power device 120 will inevitably reduce the amount of water pipe used, for example, by shortening the length of the water pipes.
[0066] Please see Figure 6 and Figure 7 The liquid injection channel 131 is provided with a liquid injection inlet 1311, and the liquid outlet 122 of the power component 120 is connected to the liquid injection inlet 1311 to draw liquid from the liquid storage chamber 111 into the liquid injection channel 131 of the channel component 130. The liquid outlet 122 of the power component 120 can be directly connected to the liquid injection inlet 1311, or connected to the liquid injection inlet 1311 through a water pipe. The liquid injection channel 131 is connected to the liquid supply port 136, which is connected to the outside, so that the liquid in the liquid injection channel 131 can be discharged through the liquid supply port 136, for example, it can be discharged to the cleaning component 210 of the cleaning device 1000 to wet the cleaning component 210 and thus achieve wet mopping. The liquid injection inlet 1311 and the liquid supply port 136 can be openings opened on the channel component 130, or outwardly protruding pipe joints, or inwardly recessed installation areas. The specific structure of the injection inlet 1311 and the supply port 136 is not limited in this application.
[0067] Compared to related technologies where the liquid storage component, power component, and multiple liquid supply ports of cleaning equipment are all connected by water pipes, resulting in a large number and length of water pipes, the liquid supply assembly 100 provided in one or more embodiments of this application achieves communication between the liquid storage component 110 and the power component 120, and between the power component 120 and the liquid supply ports 136, through a flow channel component 130 with multiple internal flow channels. This saves on the amount of water pipes used, reducing the cost and space occupied by the liquid supply assembly 100. Furthermore, the flow channels within the flow channel component 130 are clearly arranged, preventing problems such as reduced cross-section or blockage caused by external interference, thus ensuring the liquid supply effect of the liquid supply assembly 100 and improving the cleaning performance of the cleaning equipment 1000 equipped with the liquid supply assembly 100.
[0068] Since the liquid storage component 110 and the power component 120 are connected through the flow channel 130, the liquid storage component 110 and the power component 120 can be installed in different positions without needing to be close to each other. This allows for a more flexible arrangement of the liquid supply assembly 100. Please refer to... Figure 5 and Figure 6 In some embodiments, the flow channel 130 has a first end A and a second end B disposed opposite to each other along the extending direction of the liquid extraction flow channel 132. The position of one end of the liquid extraction flow channel 132 in its extending direction can be designated as the first end A of the flow channel 130, and the position of the other end of the liquid extraction flow channel 132 in its extending direction can be designated as the second end B of the flow channel 130. In this case, the first end A and the second end B can be either the physical ends of the flow channel 130 or any position (not an end position) of the flow channel 130. Of course, in some embodiments, the physical ends of the flow channel 130 in the extending direction of the liquid extraction flow channel 132 can also be designated as the first end A and the second end B, respectively. Regardless of the above structure, it is clear that the first end A and the second end B of the flow channel 130 are separated from each other by a considerable distance in the extending direction of the liquid extraction flow channel 132.
[0069] The liquid reservoir 110 is installed closer to the first end A of the flow channel 130 than the power unit 120, while the power unit 120 is installed closer to the second end B of the flow channel 130 than the liquid reservoir 110. Figure 5 As shown. Since both the liquid storage component 110 and the power component 120 are relatively large components, with the diversification of functions of the cleaning equipment 1000, there may not be enough space in the cleaning equipment 1000 to place the liquid storage component 110 and the power component 120 side by side. However, the liquid supply assembly 100 provided in one or more embodiments of this application separates the liquid storage component 110 and the power component 120 at the first end A and the second end B of the flow channel component 130, thereby separating the installation positions of the liquid storage component 110 and the power component 120 and making it convenient to arrange the liquid storage component 110 and the power component 120 in the available space.
[0070] The liquid storage component 110 and the power component 120 can be directly installed on the flow channel component 130, and the connection between the liquid storage component 110 and the flow channel component 130, and the connection between the power component 120 and the flow channel component 130, can be achieved by aligning the openings together. Alternatively, the liquid storage component 110 and the power component 120 can be installed beside the flow channel component 130 and connected to the flow channel component 130 through a pipe.
[0071] Please see Figure 5 and Figure 6In some embodiments, the liquid extraction channel 132 is provided with a liquid extraction inlet 1321 and a liquid extraction outlet 1322. The liquid extraction inlet 1321 communicates with the injection port 112 of the liquid storage component 110, and the liquid extraction outlet 1322 communicates with the liquid extraction port 121 of the power component 120. In some embodiments, the liquid extraction inlet 1321 is located at the first end A of the channel component 130, and the installation position of the liquid storage component 110 is close to the first end A of the channel component 130. This results in a shorter length of the pipe connecting the injection port 112 of the liquid storage component 110 and the liquid extraction inlet 1321 of the channel component 130 (hereinafter referred to as injection pipe a). Figure 5 As shown.
[0072] Please see Figure 5 and Figure 6 In some embodiments, the injection inlet 1311 and the extraction outlet 1322 are both closer to the second end B of the flow channel 130 than the extraction inlet 1321. The power unit 120 is installed at the second end B of the flow channel 130, thereby making the pipe connecting the extraction port 121 of the power unit 120 to the extraction outlet 1322 of the flow channel 130 (hereinafter referred to as extraction pipe b), and the pipe connecting the outlet 122 of the power unit 120 to the injection inlet 1311 of the flow channel 130 (hereinafter referred to as outlet pipe c) both relatively short. Figure 5 As shown. In addition, because the liquid storage component 110 and the power component 120 are arranged at intervals, the position of the liquid injection pipe a is also spaced apart from the positions of the liquid extraction pipe b and the liquid outlet pipe c. The pipe layout is clear and will not intersect, thereby greatly reducing the incidence of pipe pressure or even pipe bursting.
[0073] Please see Figure 5 , Figure 6 and Figure 7 In some embodiments, the flow channel 130 is further provided with an overflow channel 133. The liquid storage component 110 is also provided with an overflow port 113 communicating with the liquid storage chamber 111, and the overflow port 113 is communicating with the overflow channel 133. By providing the overflow port 113, on the one hand, when the liquid level in the liquid storage chamber 111 exceeds the position of the overflow port 113, the excess liquid will flow out from the overflow port 113 and flow to the overflow channel 133, avoiding excessive liquid in the liquid storage chamber 111, which would lead to increased water pressure and cause the liquid storage component 110 to open or break accidentally; on the other hand, during the process of replenishing liquid to the liquid storage component 110, the air in the liquid storage chamber 111 can be discharged through the overflow port 113 to maintain the air pressure balance in the liquid storage chamber 111, so that the liquid can smoothly enter the liquid storage chamber 111.
[0074] The overflow channel 133 can temporarily store liquid overflowing from the liquid chamber 111, or it can discharge liquid overflowing from the liquid chamber 111 to the outside of the flow channel 130. In some embodiments, at least one of the overflow channel 133 and the injection channel 131 is provided with the aforementioned liquid supply port 136. That is, the liquid supply port 136 of the flow channel 130 is provided on the overflow channel 133 and / or the injection channel 131.
[0075] In one implementation, the overflow channel 133 is connected to the injection channel 131, and the overflow channel 133 is provided with the aforementioned liquid supply port 136. Since the overflow channel 133 is connected to the injection channel 131, the injection channel 131 can be connected to the liquid supply port 136 through the overflow channel 133, and the liquid in both the overflow channel 133 and the injection channel 131 flows out through the liquid supply port 136. The overflow channel 133 can have two or more liquid supply ports 136, and these ports are spaced apart to enable multi-point liquid supply.
[0076] In another embodiment, the overflow channel 133 is connected to the injection channel 131, and the injection channel 131 is provided with the aforementioned supply port 136. Since the overflow channel 133 is connected to the injection channel 131, the overflow channel 133 can connect to the supply port 136 through the injection channel 131, and the liquid in both the overflow channel 133 and the injection channel 131 flows out through the supply port 136. The injection channel 131 can have two or more supply ports 136, and these ports are spaced apart to enable multi-point liquid supply.
[0077] In another embodiment, the overflow channel 133 is connected to the liquid extraction channel 132, and the overflow channel 133 and the liquid extraction channel 132 jointly store the liquid overflowing from the liquid chamber 111. The injection channel 131 is provided with the aforementioned liquid supply port 136. The number of liquid supply ports 136 can be two or more, and the liquid supply ports 136 are distributed at intervals to enable multi-point liquid supply.
[0078] In another embodiment, the overflow channel 133, the liquid extraction channel 132, and the liquid injection channel 131 are independent of each other, and both the overflow channel 133 and the liquid injection channel 131 are provided with the aforementioned liquid supply port 136. That is to say, the liquid in the storage chamber 111 is eventually discharged from the flow channel component 130 through the liquid supply port 136 of the overflow channel 133 and the liquid supply port 136 of the liquid injection channel 131. The flow channel component 130 has a large number of liquid supply ports 136, a large liquid supply area, and a relatively uniform liquid supply.
[0079] In other embodiments, pressure balance within the liquid storage chamber 111 can also be achieved by providing a balancing valve 115 on the liquid storage component 110. See also... Figure 8The liquid storage unit 110 is equipped with a balancing valve 115, which can be an umbrella valve that allows airflow but not liquid. Furthermore, when the overflow channel 133 is connected to the injection channel 131, the balancing valve 115 can also prevent liquid in the injection channel 131 from flowing back into the liquid storage unit 110 through the overflow pipe when the flow channel plate supplies liquid to the outside.
[0080] Please see Figure 9 and Figure 10 In some embodiments, the overflow channel 133, the extraction channel 132, and the injection channel 131 are independent of each other, and the extraction channel 132 is located between the overflow channel 133 and the injection channel 131. That is, the overflow channel 133 and the injection channel 131 are distributed on opposite sides of the extraction channel 132, and the overflow channel 133 and the injection channel 131 are separated by the extraction channel 132 to ensure uniform liquid supply to both sides of the channel component 130.
[0081] Please see Figure 9 and Figure 10 In some embodiments, the overflow channel 133 is provided with an overflow inlet 1331 and at least one overflow outlet 1332 communicating with the outside. The overflow port 113 of the liquid storage component 110 is connected to the overflow inlet 1331 of the overflow channel 133 through an overflow pipe d. In some embodiments, in addition to having an injection inlet 1311, the injection channel 131 is also provided with at least one injection outlet 1312 communicating with the outside. Each overflow outlet 1332 and each injection outlet 1312 can serve as a liquid supply port 136 for the channel component 130.
[0082] The overflow inlet 1331 of the overflow channel 133 and the liquid inlet 1321 of the liquid extraction channel 132 are both directly connected to the liquid storage chamber 111 of the liquid storage member 110. In some embodiments, the overflow inlet 1331 and the liquid inlet 1321 of the liquid extraction channel 132 are both located at one end of the channel member 130 near the liquid storage member 110. For example, the overflow inlet 1331 and the liquid inlet 1321 of the liquid extraction channel 132 can both be arranged at the first end of the channel member 130, thereby making the lengths of the overflow pipe d and the injection pipe a relatively short. Figure 5 As shown.
[0083] Please see Figure 10In some embodiments, the overflow channel 133 includes a connected overflow inlet section 1333 and at least one overflow outlet section 1334. The overflow inlet 1331 is located in the overflow inlet section 1333; each overflow outlet section 1334 is provided with at least one overflow outlet 1332. By providing at least one overflow outlet section 1334, and each overflow outlet section 1334 being provided with at least one overflow outlet 1332, the overflow channel 133 has multiple spaced overflow outlets 1332, thereby expanding the liquid supply area of the overflow channel 133.
[0084] Since the overflow inlet 1331 is located at the end of the flow channel 130 closest to the liquid storage member 110, when there are two or more overflow outlet sections 1334, providing multiple overflow outlet sections 1334 ensures that the end of the flow channel 130 furthest from the liquid storage member 110 can also have an overflow outlet 1332. The overflow inlet section 1333 serves as the main channel of the overflow flow channel 133, and at least one overflow outlet section 1334 serves as a branch channel of the overflow flow channel 133. To ensure uniform distribution of liquid in each branch channel, in some embodiments, each overflow outlet section 1334 is connected to the overflow inlet section 1333 at the same location, and the flow path length of each overflow outlet 1332 from the connection point 1335 between the overflow inlet section 1333 and the overflow outlet section 1334 is the same. In other words, the flow path length between each overflow outlet 1332 and the overflow inlet 1331 is the same, and the liquid in the overflow channel 133 can flow out evenly from each overflow outlet 1332.
[0085] Please see Figure 10 , Figure 10 In the illustrated embodiment, the overflow channel 133 has one overflow inlet section 1333 and two overflow outlet sections 1334. The overflow inlet 1331 is located at the beginning of the overflow inlet section 1333. Both overflow outlet sections 1334 are connected to the end of the overflow inlet section 1333, and the connection point 1335 is a distance away from the end of the overflow inlet section 1333. This part can serve as a buffer area to reduce the flow resistance when the liquid in the overflow inlet section 1333 enters the two overflow outlet sections 1334. The length and outline of the two overflow outlet sections 1334 are basically the same, and each of the two overflow outlet sections 1334 is provided with an overflow outlet 1332 at its end.
[0086] In some embodiments, the flow path length from each injection outlet 1312 of the injection channel 131 to the injection inlet 1311 is the same, allowing the liquid in the injection channel 131 to flow out uniformly from each injection outlet 1312. The injection channel 131 can adopt the structure of an overflow channel 133, having one main channel and multiple branch channels; please refer to [link to relevant documentation]. Figure 10In some embodiments, the injection channel 131 can also be a single channel. By setting the injection inlet 1311 at the midpoint of the single channel and setting an injection outlet 1312 at each end of the single channel, it can be ensured that the flow path length between each injection outlet 1312 and the injection inlet 1311 is the same.
[0087] The channel structures provided on the flow channel component 130, such as the liquid extraction inlet 1321, liquid extraction outlet 1322, liquid injection inlet 1311, liquid injection outlet 1312, overflow inlet 1331, overflow outlet 1332, and liquid supply port 136, can specifically take the form of openings on the flow channel component 130, or protruding pipe fittings or liquid outlets on the flow channel component 130. Please refer to [link / reference]. Figure 6 In some embodiments, the first side of the flow channel component 130 is provided with a plurality of protruding pipe joints, the internal channels of which serve as a liquid inlet 1321, a liquid outlet 1322, a liquid injection inlet 1311, and an overflow inlet 1331, respectively. By setting the liquid inlet 1321, liquid outlet 1322, liquid injection inlet 1311, and overflow inlet 1331 in the form of pipe joints, it is convenient to install pipes between the flow channel component 130 and the liquid storage component 110 and the power component 120. The second side of the flow channel component 130 is provided with a plurality of protruding liquid outlets, the internal channels of which serve as a liquid injection outlet 1312 and an overflow outlet 1332, respectively. By setting the liquid injection outlet 1312 and overflow outlet 1332 in the form of liquid outlets, it is convenient for the liquid supply assembly 100 to be installed inside the equipment, and for the liquid outlets to pass through the outer shell of the equipment to supply liquid to the outside.
[0088] The flow channel component 130 can be an independent flow channel plate; it can also be integrated with the equipment that configures the liquid supply assembly 100, i.e., the equipment has multiple flow channels, and the component containing these multiple flow channels constitutes the flow channel component 130, and these multiple flow channels respectively constitute the liquid extraction flow channel 132, the liquid injection flow channel 131, etc. When the flow channel component 130 is an independent component, it can be a one-piece structure, formed by injection molding, machining, 3D printing, etc. The flow channel component 130 can also be a split structure, including multiple components, which are sealed together to form multiple flow channels. Using a split structure reduces the manufacturing difficulty of the flow channel component 130 and allows for the formation of flow channels with multiple curved structures.
[0089] Please see Figure 11The diagram shows a cross-sectional view of the flow channel 130 in some embodiments. The flow channel 130 includes a first component 134 and a second component 135. At least one of the first component 134 and the second component 135 is provided with a groove, and the first component 134 is sealed to the second component 135 to enclose the groove to form a liquid extraction channel 132 and a liquid injection channel 131. When the flow channel 130 also includes an overflow channel 133, at least one of the first component 134 and the second component 135 is provided with a groove, and the first component 134 is sealed to the second component 135 to enclose the groove to form a liquid extraction channel 132, a liquid injection channel 131, and an overflow channel 133.
[0090] In some embodiments, only one of the first component 134 and the second component 135 may have a groove, while the other may be a cover plate. For example, the first component 134 may have three grooves, and the second component 135 may be a cover plate that covers and seals the first component 134, thereby forming a liquid extraction channel 132, a liquid injection channel 131, and an overflow channel 133, respectively. This design divides the first component 134 and the second component 135 along the depth of the grooves.
[0091] In other embodiments, both the first component 134 and the second component 135 may be provided with grooves. For example, both the first component 134 and the second component 135 may be provided with three grooves. The three grooves in the first component 134 and the second component 135 have the same shape, length, and distribution position. After the first component 134 and the second component 135 are fastened and sealed together with their groove openings facing each other, the three grooves respectively form a liquid extraction channel 132, a liquid injection channel 131, and an overflow channel 133. This scheme also divides the first component 134 and the second component 135 along the depth of the grooves.
[0092] When the groove is divided in half along its depth into a first component 134 and a second component 135, the depth of the groove in the first component 134 is the same as the depth of the groove in the second component 135. In some embodiments, the depth of the groove in the first component 134 is greater than the depth of the groove in the second component 135, and the liquid supply port 136 is located on the first component 134. That is, when the flow channel component 130 is installed, the first component 134 faces downward, and the liquid discharged from the liquid supply port 136 can be smoothly discharged under the action of liquid pressure and its own weight. The greater depth of the groove in the first component 134 ensures that even if leakage occurs at the connection between the first component 134 and the second component 135, the leakage amount can be reduced because the leakage point is relatively high.
[0093] In some embodiments, both the first component 134 and the second component 135 may be provided with grooves. For example, both the first component 134 and the second component 135 may be provided with inner partitions, thereby forming two grooves of different widths on the first component 134 and the second component 135 respectively. The inner partitions of the first component 134 and the second component 135 are staggered. After the first component 134 and the second component 135 are fastened and sealed together with their grooves facing each other, the two staggered inner partitions form a liquid extraction channel 132 located in the middle, and the outer sides of the two inner partitions form an injection channel 131 and an overflow channel 133 respectively. This scheme divides the first component 134 and the second component 135 along the width of the groove.
[0094] It is understandable that the flow channel component 130 can also be composed of three, four, or more sub-components. Further sub-component schemes for the flow channel component 130 will not be exhaustively listed here.
[0095] Please see Figure 9 and Figure 10 In some embodiments, the first component 134 is installed below the second component 135, that is, when the flow channel component 130 is fixed, the first component 134 faces downward and the second component 135 faces upward. The liquid inlet 1321, liquid outlet 1322, liquid injection inlet 1311, and overflow inlet 1331 are all located on the second component 135 for easy connection with the liquid storage component 110 and the power component 120. The liquid injection outlet 1312 and overflow outlet 1332 are both located on the first component 134 to facilitate liquid flowout by gravity.
[0096] The sealing connection between the various components of the flow channel component 130 can be achieved by adhesive bonding, welding (e.g., ultrasonic welding), heat fusion, or by fastening or clamping the sealing ring with fasteners. This application does not limit the specific sealing method.
[0097] Please see Figure 11 and Figure 11A The diagram shows a cross-sectional view of the flow channel component 130 and an enlarged view of the sealing connection in some embodiments. The mating surfaces of the first component 134 and the second component 135 of the flow channel component 130 are provided with a tongue-and-groove sealing structure. For example, please refer to... Figure 11A In some embodiments, the mating surface of the first component 134 is provided with a sealing protrusion 1341, and the mating surface of the second component 135 is provided with a sealing recess 1351. During assembly, the sealing protrusion 1341 is embedded in the sealing recess 1351, and the sealing protrusion 1341 and the sealing recess 1351 are fixed together by adhesive or ultrasonic welding, thereby forming a labyrinthine sealing structure on the mating surfaces of the first component 134 and the second component 135, maintaining good sealing performance. Based on this, the sealing effect of the flow channel component 130 can be guaranteed without using a seal.
[0098] Please see Figure 12 According to a second aspect of this application, a cleaning device 1000 is provided. This cleaning device 1000 can be a sweeping robot, a mopping robot, a combined sweeping and mopping robot, a floor scrubber, etc. The cleaning device 1000 includes a device body 200 and a liquid supply assembly 100 as described in any embodiment of the first aspect. The device body 200 is provided with a cleaning component 210, which can be at least one of a mop 211, a sponge, a roller brush 212, a side brush 213, etc. The cleaning component 210 can be installed at the bottom of the device body 200 and contact the surface to be cleaned.
[0099] The liquid supply assembly 100 is connected to the main body 200. The liquid supply assembly 100 can be installed entirely inside the main body 200; or only some components can be installed inside the main body 200, for example, the liquid storage component 110 is exposed relative to the main body 200, and the user can directly add liquid to the liquid storage component 110.
[0100] In some embodiments, the liquid supply port 136 of the liquid supply assembly 100 corresponds to the position of the cleaning component 210 to supply liquid to the cleaning component 210. The correspondence between the liquid supply port 136 and the cleaning component 210 can be that the liquid supply port 136 is located above the cleaning component 210, or that the cleaning component 210 is located in the path of the liquid supplied by the liquid supply port 136. In short, it is sufficient to ensure that the liquid supplied by the liquid supply port 136 contacts the cleaning component 210. In other embodiments, the liquid supply port 136 of the liquid supply assembly 100 can also be positioned to correspond to the position of the dust suction port or dust suction pipe of the cleaning equipment 1000, enabling the spraying of liquid onto the dust suction port or dust suction pipe to achieve the function of dust suppression through spraying.
[0101] In some embodiments, the flow channel 130 is provided with an overflow channel 133, which is also provided with a liquid supply port 136. The liquid supply port 136 of the overflow channel 133 also corresponds to the position of the cleaning component 210, so that the cleaning component 210 can directly absorb the liquid overflowing from the liquid storage component 110. On the one hand, this improves the utilization rate of the liquid and reduces waste; on the other hand, it avoids the direct discharge of overflowing liquid and the formation of water stains on the surface to be cleaned, thereby improving the user experience.
[0102] Please see Figure 13This diagram illustrates the connection structure between the liquid supply assembly 100 and the main body 200 in a cleaning device 1000 according to certain embodiments. The liquid supply assembly 100's reservoir 110, flow channel 130, and power unit 120 are sequentially distributed along the circumference of the main body 200. The reservoir 110, flow channel 130, and power unit 120 are connected to the bottom shell 220 of the main body 200 via fasteners, facilitating installation and disassembly. In some embodiments, the flow channel 130 is located close to the outer periphery of the main body 200, and its shape can be adaptively designed according to the main body 200. Taking a common circular cleaning robot as an example, where the main body 200 is cylindrical, the flow channel 130 has a certain curvature.
[0103] Based on the fact that flow channel component 130 has a flat flow channel plate structure and a low height, please refer to [link / reference needed]. Figure 13 In some embodiments, the power component 120 is stacked above the flow channel component 130. Firstly, this saves circumferential space in the main body 200; secondly, it further shortens the lengths of the liquid extraction pipe b and the liquid outlet pipe c; and thirdly, it reduces the contact area between the power component 120 and the main body 200, thereby reducing vibration noise transmitted from the power component 120 to the main body 200. In some embodiments, a shock-absorbing pad may also be provided between the power component 120 and the flow channel component 130.
[0104] Please see Figure 14 In some embodiments, the bottom shell 220 of the device body 200 has one or more through holes 221. The number and distribution of the through holes 221 are exactly the same as the liquid supply ports 136 of the flow channel component 130, and each liquid supply port 136 corresponds one-to-one with each through hole 221. The liquid supply port 136 can be an opening provided on the flow channel component 130, which is positioned opposite to the through hole 221 to achieve communication. Please refer to [link to relevant documentation]. Figure 14 In some embodiments, the liquid supply port 136 is a plurality of protruding liquid outlets provided on the flow channel 130, and the liquid outlets extend into the corresponding through holes 221, which are closer to the cleaning component 210.
[0105] Please see Figure 14 In some embodiments, a seal 240 is provided between the flow channel 130 and the bottom shell 220. The seal 240 surrounds the outer periphery of the liquid supply port 136 and the through hole 221 to ensure sealing and prevent liquid leakage into the interior of the device body 200. The seal 240 can be a rubber gasket or a silicone gasket, and this application is not limited thereto.
[0106] Please see Figure 14In some embodiments, the bottom shell 220 is provided with a recessed mounting groove 222. The shape and size of the mounting groove 222 are adapted to the flow channel component 130. The flow channel component 130 is embedded in the mounting groove 222, and each through hole 221 is provided at the bottom of the mounting groove 222. The flow channel component 130 is embedded in the mounting groove 222, which on the one hand reduces the height space occupied by the flow channel component 130, making it convenient to arrange other components (such as the power component 120) above the flow channel component 130; on the other hand, the mounting groove 222 limits the flow channel component 130, so that the flow channel component 130 is fixed in position with the bottom shell 220, preventing the flow channel component 130 from moving and causing the pipe connected to it to become loose.
[0107] Please see Figure 15 In some embodiments, the cleaning device 1000 also has an automatic liquid replenishment function. The main body 200 is provided with a liquid replenishment component 230, which is connected to the liquid storage component 110, allowing liquid to be replenished into the liquid storage component 110. The liquid replenishment component 230 can be a pipe interface, connected to the liquid storage component 110 via a liquid replenishment pipe e. This pipe interface can be connected to a faucet or a liquid replenishment nozzle of a cleaning base station, thereby filling the liquid storage chamber 111 with liquid.
[0108] Please see Figure 16 In some embodiments, the replenishing component 230 is provided with a one-way valve 231 to ensure that the liquid can only flow into the liquid storage chamber 111, and the liquid in the liquid storage chamber 111 will not flow out of the replenishing component 230.
[0109] Please see Figure 17 In some embodiments, the replenishing component 230, the storage component 110, the flow channel component 130, and the power component 120 are all connected by soft rubber tubes, that is, the injection pipe a, the extraction pipe b, the outlet pipe c, the overflow pipe d, and the replenishing pipe e are all soft rubber tubes.
[0110] In some implementations, please refer to Figure 3 The liquid storage device 110 is equipped with three pipe joints: pipe joint 110a, which serves as an injection port 112; pipe joint 110d, which serves as an overflow port 113; and pipe joint 110e, which serves as a replenishment port 114. Of the three pipe joints of the liquid storage device 110, pipe joints 110d and 110e are located at the upper part of the liquid storage device 110 for easy replenishment of liquid to the liquid storage device 110; pipe joint 110a is located at the lower part of the liquid storage device 110 for easy outflow of liquid from the liquid storage chamber 111 under its own weight.
[0111] In some implementations, please refer to Figure 5The power component 120 has two pipe fittings: pipe fitting 120b, serving as a liquid extraction port 121, and pipe fitting 120c, serving as a liquid outlet 122. The flow channel component 130 has four pipe fittings: pipe fitting 130a, serving as a liquid extraction inlet 1321; pipe fitting 130b, serving as a liquid extraction outlet 1322; pipe fitting 130c, serving as a liquid injection inlet 1311; and pipe fitting 130d, serving as an overflow inlet 1331. Please refer to... Figure 16 The fluid replenishment component 230 is equipped with a pipe connector 230e.
[0112] Please combine Figure 5 The two ends of the injection pipe a are respectively fitted onto pipe fittings 110a and 130a; the two ends of the extraction pipe b are respectively fitted onto pipe fittings 120b and 130b; the two ends of the outlet pipe c are respectively fitted onto pipe fittings 120c and 130c; the two ends of the overflow pipe d are respectively fitted onto pipe fittings 110d and 130d. The two ends of the replenishment pipe e are respectively fitted onto pipe fittings 110e and 230e, as shown below. Figure 16 As shown.
[0113] In some embodiments, the replenishing component 230 is closer to the outer periphery of the bottom shell 220 than the flow channel component 130, and the replenishing component 230 is not directly connected to the flow channel component 130. This results in the replenishing pipe e being staggered with the injection pipe a, the extraction pipe b, the outlet pipe c, and the overflow pipe d. The injection pipe a, the extraction pipe b, the outlet pipe c, the overflow pipe d, and the replenishing pipe e will not intersect, thereby greatly reducing the probability of pipe compression or even pipe bursting inside the cleaning equipment 1000.
