Detailed Implementation

[0048] 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.

[0049] 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.

[0050] 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, occupies a significant amount of internal installation space, and affects the overall size of the cleaning equipment. Furthermore, the crisscrossing and disorderly arrangement of multiple water pipes makes them prone to pressure or bending, leading to poor liquid flow or even pipe bursts, thus affecting the cleaning performance of the equipment.

[0051] Therefore, this application proposes a liquid supply component and a cleaning device, which aims to solve to some extent the technical problems of related cleaning devices having many water pipes, occupying a large space, and having messy water pipe layout, which easily leads to pipe compression.

[0052] 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.

[0053] Please see Figure 1 , Figure 2 and Figure 3 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, the power component 120, and the flow channel component 130 are sequentially connected, and the overflow port 113 of the liquid storage component 110 is directly connected to the flow channel component 130. The liquid stored in the liquid storage component 110 is discharged through the flow channel component 130, thereby supplying 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.

[0054] Please see Figure 4 , Figure 5 and Figure 5A The 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, an injection port 112 communicating with the liquid storage chamber 111, and an overflow port 113 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, then the component containing the cavity constitutes the liquid storage component 110, and the cavity constitutes the liquid storage chamber 111.

[0055] 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.

[0056] An overflow port 113 is located at the top of the liquid storage component 110. 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 into the flow channel 131 of the flow channel component 130. This prevents excessive liquid in the liquid storage chamber 111 from increasing water pressure and causing the liquid storage component 110 to open or break unexpectedly. Furthermore, during the process of replenishing liquid into 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, allowing the liquid to smoothly enter the liquid storage chamber 111.

[0057] 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 6 The liquid storage unit 110 is equipped with a balancing valve 115, which can be an umbrella valve that allows airflow but not liquid. Furthermore, by providing a balancing valve 115 on the liquid storage unit 110, it is also possible to prevent the liquid in the flow channel 131 from flowing back into the liquid storage unit 110 through the overflow pipe when the flow channel 131 plate supplies liquid to the outside.

[0058] 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.

[0059] 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.

[0060] Please see Figure 7 The flow channel 130 is provided with a flow channel 131 and at least one liquid supply port 136. The flow channel 131 may be located inside the flow channel 130, or the flow channel 130 may be formed by the flow channel 130 enclosing the surrounding environmental elements. The liquid injection port 112 of the liquid storage component 110 is connected to the liquid extraction port 121 of the power component 120, so that the power component 120 can extract the liquid from the liquid storage chamber 111 of the liquid storage component 110. The liquid outlet 122 of the power component 120 and the overflow port 113 of the liquid storage component 110 are respectively connected to the flow channel 131, so that the power component 120 can extract the liquid from the liquid storage chamber 111 into the flow channel 131 of the flow channel 130, and excess liquid in the liquid storage component 110 can also enter the flow channel 131 of the flow channel 130. The flow channel 131 is connected to the outside through the liquid supply port 136, thereby allowing the liquid in the flow channel 131 to be discharged out 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. There can be two or more liquid supply ports 136, and the liquid supply ports 136 are distributed at intervals to achieve multi-point liquid supply.

[0061] Compared to related technologies where the cleaning equipment 1000's liquid storage component 110, power component 120, and several liquid supply ports 136 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 has a flow channel component 130 that is connected to both the liquid storage component 110 and the power component 120 through an internally provided flow channel 131. The flow channel 131 of the flow channel component 130 functions as a water pipe in the related technologies. It is understood that the liquid storage component 110 and the power component 120 can be directly connected to the flow channel 131, or the liquid injection port 112 of the liquid storage component 110 and the liquid extraction port 121 of the power component 120 can be connected to the flow channel 131 respectively through water pipes. Regardless of the scheme, since the liquid storage component 110 and the power component 120 are respectively connected to the flow channel 131 of the flow channel component 130, and the flow channel 131 is connected to the outside through the liquid supply port 136, the setting of the flow channel component 130 will inevitably reduce the amount of water pipe used, for example, by shortening the length of the water pipe used, thereby reducing the cost and space occupied by the liquid supply component 100.

[0062] Furthermore, in related technologies, the water channel plate has two independent water channels: an overflow water channel and an injection water channel. This results in low space utilization of the water channel plate and a messy layout of the external water pipes. Additionally, the equipment with the water channel plate requires numerous openings to secure it. In contrast, the liquid supply assembly 100 provided in one or more embodiments of this application, because the outlet 122 of the power component 120 and the overflow port 113 of the storage component 110 are respectively connected to the flow channel 131, allows the flow channel component 130 to have only one flow channel 131. This results in a simple internal flow channel 131, high space utilization within the flow channel component 130, and further reduces the volume of the flow channel component 130, making the structure of the cleaning equipment 1000 equipped with this liquid supply assembly 100 more compact.

[0063] Please see Figure 7 and Figure 8 The flow channel 131 is provided with an injection inlet 132 and an overflow inlet 133. The injection inlet 132 is connected to the outlet 122; the overflow inlet 133 is connected to the overflow outlet 113. The outlet 122 of the power component 120 is connected to the injection inlet 132, drawing liquid from the storage chamber 111 into the flow channel 131 of the flow channel component 130. The overflow outlet 113 of the storage component 110 is connected to the overflow inlet 133, allowing excess liquid in the storage component 110 to enter the flow channel 131 of the flow channel component 130. The injection inlet 132, overflow inlet 133, and supply outlet 136 can be openings on the flow channel component 130, outwardly protruding pipe fittings, or inwardly recessed installation areas. The specific structure of the injection inlet 132, overflow inlet 133, and supply outlet 136 is not limited in this application.

[0064] Please see Figure 7 and Figure 8 In some embodiments, the injection inlet 132 and the overflow inlet 133 are located at the same end of the flow channel 130. This makes the pipe connecting the overflow port 113 of the reservoir 110 and the overflow inlet 133 (hereinafter referred to as overflow pipe c), and the pipe connecting the outlet port 122 of the power unit 120 and the injection inlet 132 (hereinafter referred to as outlet pipe b) close to each other, and the overflow pipe c and the outlet pipe b can be fixed at the same time using a constraint (e.g., clamp, strap).

[0065] Please see Figure 8 In some embodiments, the flow channel component 130 has a first end A and a second end B disposed opposite to each other. That is, the ends of the physical structure of the flow channel component 130 in the extension direction of the flow channel 131 are respectively the first end A and the second end B. It is clear that the first end A and the second end B of the flow channel component 130 are separated from each other in the extension direction of the flow channel 131 and are separated by a considerable distance.

[0066] The liquid storage component 110 and the power component 120 can be directly installed on the flow channel component 130, achieving communication between the liquid storage component 110 and the flow channel component 130, and between the power component 120 and the flow channel component 130, by aligning their openings. Alternatively, the liquid storage component 110 and the power component 120 can be installed beside the flow channel component 130 and connected to it via pipes. Since both the liquid storage component 110 and the power component 120 need to be connected to the flow channel component 130, their installation positions can be close to each other. This shortens the connection distance between the liquid storage component 110, the power component 120, and the flow channel component 130, reducing the amount of water pipe used.

[0067] Please see Figure 7 and Figure 8 In some embodiments, both the liquid storage component 110 and the power component 120 are located close to the first end A of the flow channel component 130, and both the injection inlet 132 and the overflow inlet 133 are located at the first end A. This results in the following: the pipe connecting the overflow port 113 and the overflow inlet 133 of the liquid storage component 110 (hereinafter referred to as overflow pipe c), the pipe connecting the injection port 112 of the liquid storage component 110 and the extraction port 121 of the power component 120 (hereinafter referred to as injection pipe a), and the pipe connecting the outlet port 122 of the power component 120 and the injection inlet 132 (hereinafter referred to as outlet pipe b) are all relatively short. Figure 7 As shown. Furthermore, the injection pipe a, the outlet pipe b, and the overflow pipe c are located close to each other. A single restraint device (such as a clamp or strap) can simultaneously fix the injection pipe a, the outlet pipe b, and the overflow pipe c, thereby preventing the pipes from intersecting due to external interference and greatly reducing the incidence of pipe pressure or even pipe bursting.

[0068] Please see Figure 9In some embodiments, the flow channel 131 is provided with a flared portion 1314, the width of which is greater than the width of other locations in the flow channel 131. The outlet 122 of the power unit 120 and the overflow port 113 of the liquid storage unit 110 are respectively connected to the flared portion 1314. The liquid supplied by the power unit 120 and the excess liquid in the liquid storage unit 110 both flow into the flared portion 1314, mix in the flared portion 1314, and then flow together to other locations in the flow channel 131. Since the area of ​​the flared portion 1314 is relatively larger than other locations in the flow channel 131, the flared portion 1314 also helps to mitigate the impact of the liquid entering the flow channel 131 from the power unit 120, reducing the flow resistance when the liquid enters the flow channel 131.

[0069] Please see Figure 9 In some embodiments, the flow channel 131 includes an inlet section 1311 and at least one outlet section 1312 communicating with the inlet section 1311. Each outlet section 1312 is provided with at least one liquid supply port 136. By providing at least one outlet section 1312, and each outlet section 1312 being provided with at least one liquid supply port 136, the flow channel 131 has a plurality of spaced-apart liquid supply ports 136, thereby increasing the liquid supply area of ​​the flow channel component 130.

[0070] In some embodiments, the outlet 122 of the power unit 120 and the overflow port 113 of the storage unit 110 are both connected to the inlet section 1311. The liquid supplied by the power unit 120 and excess liquid in the storage unit 110 both flow into the inlet section 1311 of the flow channel 131, mix in the inlet section 1311, and then flow together to the respective outlet sections 1312. In some embodiments, the installation positions of the power unit 120 and the storage unit 110 are both close to the first end A of the flow channel 130, and the connection points 1313 between the power unit 120 and the storage unit 110 and the inlet section 1311 are both located at the first end A of the flow channel 130. By providing multiple outlet sections 1312, it can be ensured that the second end B of the flow channel 130 can also be provided with a liquid supply port 136. In some embodiments, the flared portion 1314 is connected to the inlet section 1311. In other words, the liquid entering the flow channel 130 flows in the direction of flared section 1314 - inlet section 1311 - outlet section 1312 - supply port 136.

[0071] The inlet section 1311 serves as the main flow channel 131 of the flow channel 131, and at least one outlet section 1312 serves as a branch flow channel 131. To ensure uniform distribution of liquid in each branch flow channel 131, in some embodiments, each outlet section 1312 is connected to the inlet section 1311 at the same location, and the flow path length from each liquid supply port 136 to the connection point 1313 between the inlet section 1311 and the outlet section 1312 is the same. That is, the flow path length from each liquid supply port 136 to the connection point 1313 between the power unit 120 and the liquid storage unit 110 and the inlet section 1311 is the same, and the liquid in the flow channel 131 can flow out uniformly from each liquid supply port 136.

[0072] Please see Figure 9 , Figure 9 In the illustrated embodiment, the flow channel 131 has an inlet section 1311 and two outlet sections 1312. A flared portion 1314 is located at the beginning of the inlet section 1311. Both outlet sections 1312 communicate with the end of the inlet section 1311, and the communication point 1313 is a distance from the end of the inlet section 1311. This portion can serve as a buffer zone, reducing the flow resistance when liquid from the inlet section 1311 enters the two outlet sections 1312. The length and outline of the two outlet sections 1312 are substantially the same, and each outlet section 1312 has a liquid supply port 136 at its end.

[0073] The channel structures such as the injection inlet 132, overflow inlet 133, and supply outlet 136 provided on the flow channel component 130 can be, in specific structural forms, openings on the flow channel component 130, or protruding pipe fittings or outlet nozzles on the flow channel component 130. Please refer to [link / reference]. Figure 8 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 injection inlets 132 and overflow inlets 133, respectively. By setting the injection inlets 132 and overflow inlets 133 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 supply ports 136. By setting the supply ports 136 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.

[0074] The flow channel component 130 can be an independent flow channel 131 plate; it can also be integrated with the equipment that configures the liquid supply assembly 100, i.e., the equipment has flow channels 131 inside, and the component containing the flow channels 131 constitutes the flow channel component 130. 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 modular structure, comprising multiple components sealed together to form multiple flow channels 131. Using a modular structure reduces the manufacturing difficulty of the flow channel component 130 and allows for the formation of flow channels 131 with multiple curved structures.

[0075] Please see Figure 10 and Figure 11 The diagram shows a top view and a cross-sectional view of the flow channel component 130 in some embodiments. The flow channel component 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 and the second component 135 are sealed together to enclose the groove to form a flow channel 131.

[0076] In some embodiments, only one of the first component 134 and the second component 135 may be provided with a groove, while the other is a cover plate. For example, the first component 134 may be provided with one or more interconnected grooves, and the second component 135 may be a cover plate that covers the first component 134 and is sealed to the first component 134, thereby forming a flow channel 131 in the groove.

[0077] 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 a groove. The shape, length and distribution of the grooves in the first component 134 and the second component 135 are the same. After the first component 134 and the second component 135 are fastened and sealed together with their groove openings facing each other, the grooves form a flow channel 131.

[0078] 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.

[0079] 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.

[0080] 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 injection inlet 132 and the overflow inlet 133 are both located on the second component 135 for easy connection with the liquid storage component 110 and the power component 120. Each liquid supply port 136 is located on the first component 134 to facilitate liquid flowout by gravity.

[0081] 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.

[0082] 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 the seal 240.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Please see Figure 13 This 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.

[0087] Based on the fact that flow channel component 130 is a flat flow channel 131 plate structure with a low height, please refer to [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 length of the liquid outlet pipe b; thirdly, the power component 120 and the flow channel component 130 can share fasteners, thereby reducing the number of openings on the bottom shell 220; and fourthly, it reduces the contact area between the power component 120 and the main body 200, reducing vibration noise transmitted from the power component 120 to the main body 200. In some embodiments, a shock-absorbing pad can also be further provided between the power component 120 and the flow channel component 130.

[0088] Please see Figure 14In 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 component 130, with the liquid outlets extending into the corresponding through holes 221 and closer to the cleaning component 210. In some embodiments, the cleaning component 210 includes two mops 211, in which case the number of liquid supply ports 136 and through holes 221 should both be more than two, ensuring that each mop 211 is supplied with liquid through at least one liquid supply port 136.

[0089] Please see Figure 14 In 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.

[0090] Please see Figure 15 and Figure 16 In some embodiments, a seal 240 is provided between the flow channel 130 and the bottom shell 220. The seal 240 may be a rubber gasket or a silicone gasket, and this application is not limited thereto. The seal 240 surrounds at least the outer periphery of the liquid supply port 136 to ensure sealing and prevent liquid leakage into the interior of the device body 200.

[0091] The sealing element 240 can be arranged axially between the flow channel 130 and the bottom shell 220 along the liquid supply port 136. The sealing element 240 surrounds the outer periphery of the liquid supply port 136 and the through hole 221, and is clamped to the bottom shell 220 by the flow channel 130 to achieve a seal at the connection between the liquid supply port 136 and the through hole 221. In some embodiments, the liquid supply port 136 is a protruding liquid outlet, and the sealing element 240 can be embedded in the through hole 221 and wrapped around the outer periphery of the liquid outlet, thereby sealing the annular gap between the liquid outlet and the hole wall of the through hole 221.

[0092] Please see Figure 15 , Figure 16 and Figure 17In 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 d. 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. Please refer to [link to relevant documentation]. 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.

[0093] Please see Figure 15 and Figure 16 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 d being staggered with the injection pipe a, the outlet pipe b, and the overflow pipe c. The injection pipe a, the outlet pipe b, the overflow pipe c, and the replenishing pipe d will not cross each other, thereby greatly reducing the probability of pipe compression or even pipe bursting inside the cleaning equipment 1000.

[0094] Please see Figure 16 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 outlet pipe b, the overflow pipe c, and the replenishing pipe d are all soft rubber tubes.

[0095] Please see Figure 16 In some embodiments, the liquid storage component 110 is provided with three pipe joints: a pipe joint 110a serving as an injection port 112, a pipe joint 110c serving as an overflow port 113, and a pipe joint 110d serving as a replenishment port 114. Of the three pipe joints of the liquid storage component 110, pipe joints 110c and 110d are both located in the upper part of the liquid storage component 110 to facilitate replenishing the liquid storage component 110; pipe joint 110a is located in the lower part of the liquid storage component 110 to facilitate the liquid in the liquid storage chamber 111 to flow out under its own weight.

[0096] In some implementations, please refer to Figure 16 The power component 120 is equipped with two pipe joints: pipe joint 120a, which serves as a liquid extraction port 121, and pipe joint 120b, which serves as a liquid outlet 122. The flow channel component 130 is equipped with two pipe joints: pipe joint 130b, which serves as a liquid injection inlet 132, and pipe joint 130c, which serves as an overflow inlet 133. The replenishment component 230 is equipped with one pipe joint 230d.

[0097] Please combine Figure 16The two ends of the injection pipe a are fitted onto pipe joints 110a and 130a, respectively; the two ends of the outlet pipe b are fitted onto pipe joints 120b and 130b, respectively; the two ends of the overflow pipe c are fitted onto pipe joints 110c and 130c, respectively. The two ends of the replenishment pipe d are fitted onto pipe joints 110d and 230d, respectively.
