[0061] 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.

[0063] 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.

[0064] Please see Figure 1 and Figure 2 According to the first aspect of this application, a cleaning device 100 is provided, which may be a sweeping robot, a mopping robot, a sweeping and mopping robot, a floor scrubber, a vacuum cleaner, etc.

[0065] Please see Figure 3 and Figure 4 The cleaning device 100 includes at least a main body 110, a circuit board 120, a battery 130, a wheel module 140, and cleaning components 150 necessary for cleaning operations, such as a roller brush module 151, a side brush module 152, and a mopping module 153. The main body 110 serves as the mounting base for the circuit board 120, battery 130, wheel module 140, and cleaning components 150, and also defines the appearance of the cleaning device 100. The circuit board 120 and battery 130 are respectively installed in the main body 110, and the wheel module 140 and cleaning components 150 are respectively connected to the main body 110. The circuit board 120 and wheel module 140 can be electrically connected to the battery 130, which provides power.

[0066] The cleaning equipment 100 typically includes several obstacle detection devices, each electrically connected to the circuit board 120. These obstacle detection devices can be distance sensors or machine vision systems, detecting the distance between obstacles and the equipment body 110, as well as the size of the obstacles. For fixed structures such as steps and thresholds, the position and size information of each fixed obstacle can be marked on the cleaning map constructed by the cleaning equipment 100. For movable obstacles such as stools, toys, trash cans, and books, the cleaning equipment 100 needs to automatically detect them during operation.

[0067] The electrical components in the walking wheel module 140 are electrically connected to the circuit board 120 and the battery 130, respectively. Powered by the battery 130 and receiving control commands from the circuit board 120, the walking wheel module 140 guides the movement of the main body 110. During the cleaning process executed by the cleaning equipment 100, the walking wheel module 140 can move forward, backward, or rotate according to commands, enabling the cleaning equipment 100 to move forward, backward, or turn, thus reaching various positions in the area to be cleaned. Typically, two walking wheel modules 140 are provided, symmetrically distributed on both sides of the main body 110, with the axis of symmetry parallel to the direction of travel of the cleaning equipment 100.

[0068] Please see Figure 2 In some embodiments, the main body 110 of the device includes at least a top cover 112 and a bottom shell 111. The top cover 112 at least defines the top surface of the cleaning device 100, and the bottom shell 111 mainly serves a load-bearing function, used to mount the circuit board 120, battery 130, wheel module 140, and cleaning component 150. The top cover 112 and the bottom shell 111 can be configured as an integral structure containing only one part, or as a split structure composed of multiple parts, depending on actual needs. This application does not impose any restrictions.

[0069] Please see Figure 3 and Figure 4The cleaning device 100 also includes a heat reflector 160 and a heat insulation component 170, both of which are disposed within the main body 110 and located between the circuit board 120 and the battery 130. The heat insulation component 170 is located on the side of the heat reflector 160 facing away from the circuit board 120. Because the heat reflector 160 has excellent heat radiation reflection capabilities, its placement between the circuit board 120 and the battery 130 allows it to reflect the heat radiation generated by the circuit board 120 away from the battery 130. The heat insulation component 170, located on the side of the heat reflector 160 facing away from the circuit board 120, blocks heat transfer; heat not reflected by the heat reflector 160 is blocked by the heat insulation component 170. This double-layer protection by the heat reflector 160 and the heat insulation component 170 prevents heat generated by the circuit board 120 from being transferred to the battery 130, thus preventing abnormal temperature increases in the battery 130 and ensuring the operational performance of the cleaning device 100.

[0070] The battery 130 can be installed in the device body 110 using fasteners, or embedded in a cavity or slot provided in the device body 110. When the battery 130 is connected to the device body 110 using fasteners, the battery 130 can be a cell with a large flat surface, such as a square-shell cell, to facilitate fixing the battery 130. When the battery 130 is embedded in a cavity or slot provided in the device body 110, the shape of the battery 130 is not limited.

[0071] Please see Figure 5 In some embodiments, the device body 110 is provided with a battery compartment 114 for accommodating a battery 130, the battery 130 being installed in the battery compartment 114.

[0072] Please see Figure 5 and Figure 6 To facilitate the installation of the battery 130, in some embodiments, the battery compartment 114 is configured as a slot structure with the opening facing downwards (towards the ground). The main body 110 of the device includes a bottom shell 111 and a battery compartment cover 113, with the battery compartment 114 disposed on the bottom shell 111. The battery compartment cover 113 is connected to the bottom shell 111 and covers the opening of the battery compartment 114.

[0073] In other embodiments, the battery compartment 114 may also be a channel structure with openings on both sides. The heat insulation member 170 covers one opening of the battery compartment 114 to form the bottom 1141 of the battery compartment 114. The battery compartment cover 113 covers the opening on the other side of the battery compartment 114, which may be an opening in the battery compartment 114 facing outwards towards the bottom shell 111. The heat insulation member 170, the bottom shell 111, and the battery compartment cover 113 together enclose the closed battery compartment 114, and the battery 130 is installed in the battery compartment 114.

[0074] Please see Figure 7In some embodiments, a seal 115 is provided between the battery compartment cover 113 and the bottom shell 111 to seal the gap between them and prevent water or dust from entering the battery compartment 114. The seal 115 can be a sealing ring, and a sealing groove 116 can be provided on either the battery compartment cover 113 or the bottom shell 111 to install the sealing ring in the groove and prevent displacement. When the battery compartment cover 113 and the bottom shell 111 are connected, the seal is achieved by pressing the sealing ring together. Alternatively, the seal 115 can be a sealant applied to the connection between the battery compartment cover 113 and the bottom shell 111, serving not only a sealing function but also assisting in the bonding of the battery compartment cover 113 and the bottom shell 111 through adhesive bonding.

[0075] With the battery 130 internally installed in the battery compartment 114, the circuit board 120 is located in the main body 110 of the device and near the bottom 1141 of the battery compartment 114. That is, the battery 130 and the circuit board 120 are separated by the wall of the battery compartment 114. When the wall of the battery compartment 114 is made of a poor conductor of heat, the wall of the battery compartment 114 itself can achieve a certain heat insulation effect, acting as a heat insulation element 170.

[0076] In some embodiments, the heat insulation component 170 is a component independent of the main body 110 of the equipment. The specific shape of the heat insulation component 170 can be a heat insulation pad or a heat insulation cover, and this application does not impose any limitations. The heat insulation component 170 is a poor conductor of heat. The heat insulation component 170 can be foam prepared by foaming various organic foaming materials, such as polystyrene foam (EPS, XPS), polyurethane foam (PU), phenolic foam, polyethylene foam, etc. The heat insulation component 170 can be various inorganic heat insulation materials, such as rock wool, glass wool, ceramic fiber, expanded perlite, etc. The heat insulation component 170 can also be a composite heat insulation material, such as vacuum insulation panel (VIP), aerogel composite material, aluminum foil composite heat insulation material composed of aluminum foil and polyethylene foam, glass fiber, etc. The material of the heat insulation component 170 can also be aerogel. This application does not impose any limitations on the specific material of the heat insulation component 170.

[0077] In some embodiments, the heat insulation element 170 is located between the circuit board 120 and the battery 130. The heat insulation element 170 may be disposed outside or inside the battery compartment 114; this application does not impose any limitations. Please refer to [link to relevant documentation]. Figure 8In some embodiments, the heat insulation element 170 is disposed in the battery compartment 114 and at least covers the bottom 1141 of the battery compartment 114. For example, the heat insulation element 170 may only cover the bottom 1141 of the battery compartment 114, or the heat insulation element 170 may cover both the bottom 1141 and the side walls of the battery compartment 114. The provision of the heat insulation element 170 increases the straight-line distance from the circuit board 120 to the battery 130, and since the heat insulation element 170 itself is made of heat-insulating material, it effectively blocks the transfer of heat from the circuit board 120 to the battery 130.

[0078] In some embodiments, the heat insulation element 170 is made of an elastic material that can be compressed to a certain extent, such as an aerogel pad or foam. The heat insulation element 170 is disposed under pressure between the battery 130 and the wall of the battery compartment 114. While providing heat insulation within the battery compartment 114, the heat insulation element 170 also acts as a buffer, ensuring that the battery 130 does not shake due to bumps when the cleaning device 100 moves. When installing the battery compartment cover 113, a certain interference fit is designed, and the battery compartment cover 113 compresses the heat insulation element 170 through the battery 130.

[0079] In some embodiments, the thermal insulation component 170 may be made of pre-oxidized filament aerogel felt (KNTZ). Pre-oxidized filament aerogel felt possesses excellent properties such as high flexibility, low thermal conductivity, wide applicable temperature range, fire resistance, water resistance, non-aging, and long service life, making it an ideal material for thermal insulation and protection. Pre-oxidized filament aerogel felt has an extremely low thermal conductivity, typically not exceeding approximately 0.020 W / (m·K), effectively isolating it from external high and low temperatures. This material is flexible and can be cut to fit the shape of the battery compartment 114 and the battery 130.

[0080] To facilitate the connection of battery 130 with other electrical components (such as circuit board 120), a large wiring hole 1142 needs to be provided on the wall of battery compartment 114. A gap is required between the wiring harness and the wiring hole 1142 to allow for harness movement (some electrical components need to change orientation or position when the cleaning equipment 100 is operating, and the wires need to move accordingly). However, this gap can also cause heat from circuit board 120 to spread to battery compartment 114. Therefore, the heat insulation component 170 can be made of a material with a certain degree of elasticity and flexibility (such as aerogel or foam), covering the wiring hole 1142, and perforations are drilled in the heat insulation component 170 for wiring. The size of these perforations is basically the same as the outer envelope size of the wiring harness, but because the heat insulation component 170 is flexible and has a certain degree of elasticity, even if the heat insulation component 170 tightly wraps around the wiring harness, it will not scratch the wiring harness or hinder its movement. This achieves heat insulation at the wiring hole 1142.

[0081] The device body 110 may have a recessed area for placing the circuit board 120, or it may have mounting posts with screw holes for mounting the circuit board 120. In some embodiments, the circuit board 120 is connected to the bottom shell 111 of the device body 110 by fasteners or a snap-fit ​​structure, and the heat reflector 160 is located between the circuit board 120 and the bottom shell 111. That is, the circuit board 120 and the battery 130 are distributed on opposite sides of the bottom shell 111.

[0082] In some embodiments, the battery 130 is located closer to the outer side of the bottom housing 111 than the circuit board 120. On the one hand, the battery 130 is located further out, which facilitates its replacement or maintenance; on the other hand, the circuit board 120 is located further inward, so the main body of the device 110 can provide good protection for the circuit board 120, preventing foreign objects or liquids from damaging the circuit board 120.

[0083] Circuit board 120 typically houses multiple electronic components, such as capacitors, resistors, and CPUs.

[0084] (Central Processing Unit, etc.) The CPU is one of the most important parts of the control system of the cleaning equipment 100, responsible for executing instructions in the program, performing data processing and calculation tasks. The CPU generates a lot of heat when it is working. In addition, high-power devices such as IGBTs are installed on the circuit board 120.

[0085] (Insulated-Gate-Bipolar-Transistor), capacitors, etc., can also generate heat. These components that generate a lot of heat when they are working are called heat-generating elements 121.

[0086] With the battery 130 located within the battery compartment 114, in some embodiments, the heating element 121 in the circuit board 120 is staggered from the battery compartment 114. This extends the distance for heat radiation between the heating element 121 and the battery 130, reducing the thermal impact of the heating element 121 on the battery 130 to some extent. In some embodiments, the heat reflector 160 may correspond to the position of the heating element 121 in the circuit board 120, effectively reflecting the heat radiation generated by the heating element 121.

[0087] In some embodiments where the battery 130 is located within the battery compartment 114, the heat reflector 160 is located outside the battery compartment 114 and at least covers the bottom 1141 of the battery compartment 114. For example, the heat reflector 160 may only cover the outer side of the bottom 1141 of the battery compartment 114, or the heat reflector 160 may cover both the bottom 1141 and the outer sidewalls of the battery compartment 114, achieving full coverage of the battery compartment 114.

[0088] In some embodiments, the heat reflector 160 can be a metallic material that reflects heat radiation, such as aluminum foil or copper plate. In other embodiments, the heat reflector 160 can also be a heat reflective coating applied to a substrate, which can be a ceramic coating, a silver film, or other metal oxide thin films. In some embodiments, a poor conductor of heat can be used as the substrate to further improve the heat insulation effect of the heat reflector 160. In other embodiments, the heat insulation element 170 can be used as the substrate of the heat reflective coating, that is, the heat reflector 160 and the heat insulation element 170 are an integral structure.

[0089] In some embodiments, the heat reflector 160 is an aluminum foil, which is attached to the outer side of the bottom 1141 of the battery compartment 114. See also... Figure 9 In some embodiments, the outer side of the bottom 1141 of the battery compartment 114 is provided with several support columns 117, and the circuit board 120 contacts the ends of the support columns 117, thereby creating a large gap between the circuit board 120 and the bottom 1141 of the battery compartment 114. Several clearance holes 161 can be correspondingly provided on the aluminum foil to allow the support columns 117 to pass through the clearance holes 161.

[0090] In some embodiments, the device body 110 includes at least a base shell 111, which serves as the main mounting base for the components of the cleaning device 100. A circuit board 120 is connected to the base shell 111, and a gap exists between the circuit board 120 and the base shell 111. The circuit board 120 may be spaced apart from the main body portion of the base shell 111, or it may be spaced apart from the layout of the base shell 111. For example, Figure 9 The bottom shell 111 of the illustrated embodiment is provided with a plurality of support columns 117. The circuit board 120 is connected to the bottom shell 111 by fasteners. The middle part of the circuit board 120 contacts the end of the support column 117, thereby creating a large gap between the circuit board 120 and the bottom 1141 of the battery compartment 114. Furthermore, the support columns 117 support the circuit board 120, which can improve the modal characteristics of the circuit board 120 and ensure that the circuit board 120 will not vibrate due to bumps when the cleaning equipment 100 moves.

[0091] A heat reflector 160 is located between the circuit board 120 and the bottom shell 111. In some embodiments, the heat reflector 160 is aluminum foil. The bottom 1141 of the battery compartment 114 has a large flat surface, and the aluminum foil is attached to the outside of the bottom 1141 of the battery compartment 114 for easy installation. In other embodiments, a heat reflective coating is applied to the bottom shell 111 at the position opposite to the circuit board 120 to form the heat reflector 160. The vertical projection of the circuit board 120 is within the coverage area of ​​the heat reflective coating, enabling more comprehensive reflection of the heat radiation generated by the circuit board 120.

[0092] The heat reflector 160 reflects the heat radiation generated by the circuit board 120 in a direction away from the battery 130. The heat generated by the circuit board 120 needs to be dissipated by other means. Otherwise, the heat on the circuit board 120 will continue to accumulate during operation, still affecting the battery 130. In some embodiments, the cleaning device 100 also includes a fan installed in the device body 110. The airflow generated by the fan carries away the heat generated by the circuit board 120, thereby achieving heat dissipation of the circuit board 120. In other embodiments, a heat-absorbing material can also be used to absorb the heat generated by the circuit board 120, for example, by using a phase change material to absorb heat and thus achieve heat dissipation of the circuit board 120. In other embodiments, the liquid used in the cleaning device 100 to wet the cleaning component 150 can also be used to achieve liquid cooling of the circuit board 120. More heat dissipation solutions for the circuit board 120 are not exhaustive here.

[0093] Please see Figure 10 and Figure 11 In some embodiments, the cleaning device 100 further includes a liquid supply component 180 and a heat-conducting component 190. The liquid supply component 180 is connected to the device body 110 and can supply liquid to the cleaning component 150. The liquid can be at least one of water, detergent, disinfectant, polish, floor care agent, and fragrance oil. The heat-conducting component 190 exchanges heat with the heating element 121 in the circuit board 120 and the liquid in the liquid supply component 180. By providing the heat-conducting component 190, on the one hand, the liquid in the liquid supply component 180 can be used to cool the circuit board 120, so that the circuit board 120 always operates in an optimal state; on the other hand, the heat generated by the circuit board 120 can heat the liquid in the liquid supply component 180 through the heat-conducting component 190. The heated liquid is more conducive to cleaning the surface to be cleaned. For example, hot water is easier to clean dried stains than cold water, thereby improving the cleaning effect.

[0094] The heat-conducting component 190 can directly contact the heating element 121 in the circuit board 120 and the liquid in the liquid supply component 180 to achieve heat exchange, or indirectly exchange heat through the conduction of heat by the heat-conducting material.

[0095] Please see Figure 12In one implementation scheme, the heat-conducting element 190 is made of a thermally conductive material and comes into contact with both the heating element 121 in the circuit board 120 and the liquid in the liquid supply component 180. The heat-conducting element 190 can be made of a metal material with good thermal conductivity, such as aluminum, copper, steel, or silver. The heat-conducting element 190 can directly contact the heating element 121 in the circuit board 120 to achieve heat exchange, or a thermally conductive insulating adhesive can be applied between the heat-conducting element 190 and the heating element 121 in the circuit board 120. To improve the heat exchange efficiency between the heat-conducting element 190 and the heating element 121 in the circuit board 120, the portion of the heat-conducting element 190 in contact with the heating element 121 can be in the form of a thin plate. In some embodiments, several heat dissipation fins can also be provided on the portion of the heat-conducting element 190 in contact with the heating element 121 to assist in heat dissipation.

[0096] Please see Figure 13 , Figure 13A and Figure 13B In another embodiment, the heat-conducting component 190 includes a heat-conducting part 191, which has a heat-conducting channel 1911. The heat-conducting channel 1911 communicates with the liquid storage chamber 1811, allowing liquid in the liquid storage chamber 1811 to enter the heat-conducting channel 1911. The heat-conducting part 191 exchanges heat with the heating element 121 in the circuit board 120, utilizing the cooling effect of the liquid in the heat-conducting channel 1911 to cool the heating element 121 in the circuit board 120. The heat-conducting part 191 can be made of a metal material with good thermal conductivity, such as aluminum, copper, steel, or silver. The heat-conducting part 191 can directly contact the heating element 121 in the circuit board 120 to achieve heat exchange, or thermally conductive insulating adhesive can be applied between the heat-conducting part 191 and the heating element 121 in the circuit board 120.

[0097] The connection between the heat-conducting channel 1911 and the liquid storage chamber 1811 can be located at the bottom of the liquid storage chamber 1811, and the heat-conducting channel 1911 is equivalent to an extension space of the liquid storage chamber 1811. The liquid in the liquid storage chamber 1811 flows into the heat-conducting channel 1911 under its own weight. The heat-conducting channel 1911 can be a cavity provided inside the heat-conducting part 191; please refer to [link / reference]. Figure 13B In some embodiments, the heat-conducting part 191 may also be a pipe, and the cavity of the pipe constitutes a heat-conducting flow channel 1911.

[0098] Please see Figure 13B and Figure 14 In some embodiments, the heat-conducting element 190 includes a heat-conducting portion 191 and a second power portion 192. The heat-conducting portion 191 is provided with a heat-conducting flow channel 1911, and the second power portion 192 guides the liquid in the liquid storage chamber 1811 to circulate between the liquid storage chamber 1811 and the heat-conducting flow channel 1911. The heat-conducting portion 191 exchanges heat with the heating element 121 in the circuit board 120.

[0099] The liquid circulates between the storage chamber 1811 and the heat-conducting channel, carrying away the heat transferred from the heating element 121 in the circuit board 120 to the heat-conducting part 191. After being heated, the liquid enters the storage chamber 1811 and mixes with the cooler liquid in the storage chamber 1811, thereby increasing the temperature of the liquid in the storage chamber 1811 and further improving the cleaning effect of the cleaning device 100.

[0100] The second power unit 192 can be a water pump, which is electrically connected to the circuit board 120. The circuit board 120 can receive the cooling demand signal of the heating element 121 and control the speed of the water pump according to the cooling demand of the heating element 121. When the stains on the surface to be cleaned are difficult to clean (such as dried stains, oil stains, etc.), the operator can also actively turn on the water pump. For example, the cleaning device 100 can be equipped with a switch button to control the start and stop of the water pump, or the start, stop, speed, etc. of the water pump can be controlled by a mobile terminal that communicates with the circuit board 120. The heat from the heating element 121 is used to forcibly heat the liquid in the liquid storage chamber 1811. After the liquid is heated, the effect of dissolving stains is improved, thereby efficiently removing stubborn stains and improving the cleaning effect of the cleaning device 100.

[0101] Please see Figure 12 In some embodiments, the liquid supply component 180 may only include a liquid storage section 181, which has a liquid storage chamber 1811 for storing liquid. By providing a liquid outlet hole 1814 at the bottom of the liquid storage section 181, liquid can seep out from the liquid outlet hole 1814 under its own weight and wet the cleaning component 150.

[0102] Please see Figure 15 and Figure 16 In some embodiments, the liquid supply unit 180 may include a liquid storage section 181, a liquid supply section 182, and a first power section 183. The liquid storage section 181 has a liquid storage chamber 1811 for storing liquid, and the first power section 183 guides the liquid in the liquid storage chamber 1811 into the liquid supply section 182. The liquid supply section 182 communicates with the liquid storage chamber 1811 and supplies liquid to the cleaning unit 150 through the liquid supply section 182. The liquid supply section 182 may be a nozzle, a liquid outlet, or a flow channel plate with a liquid supply port 1822; the specific structure of the liquid supply section 182 is not limited in this application.

[0103] The first power unit 183 can be electrically connected to the circuit board 120 and operated under the control of the circuit board 120. The first power unit 183 can be electrically connected to the battery 130 and powered by the battery 130. In some embodiments, the first power unit 183 can be a water pump. By setting the first power unit 183 to actively guide the liquid to the liquid supply unit 182, normal liquid outflow can be ensured even when the liquid level in the liquid storage chamber 1811 is low, thus wetting the cleaning component 150.

[0104] Please see Figure 15, Figure 16 and Figure 17 In some embodiments, the liquid storage section 181 is provided with an injection port 1812 and an overflow port 1813. The injection port 1812 and the overflow port 1813 are respectively connected to the liquid storage chamber 1811. The overflow port 1813 is located at a higher height than the injection port 1812, allowing excess liquid in the liquid storage section 181 to flow out through the overflow port 1813. The first power section 183 is provided with a suction port 1831 and a discharge port 1832. The liquid supply section 182 is provided with a liquid supply channel 1821 and at least one liquid supply port 1822. The suction port 1831 is connected to the injection port 1812; the discharge port 1832 and the overflow port 1813 are respectively connected to the liquid supply channel 1821; the liquid supply channel 1821 is connected to the outside through the liquid supply port 1822.

[0105] By connecting the injection port 1812 of the liquid storage section 181 to the extraction port 1831 of the first power section 183, the first power section 183 can extract liquid from the liquid storage chamber 1811 of the liquid storage section 181. The outlet port 1832 of the first power section 183 and the overflow port 1813 of the liquid storage section 181 are respectively connected to the supply channel 1821, so that the first power section 183 can extract liquid from the liquid storage chamber 1811 into the supply channel 1821 of the supply section 182, and excess liquid in the liquid storage section 181 can also enter the supply channel 1821 of the supply component 180. The supply channel 1821 is connected to the outside through the supply port 1822, so that the liquid in the supply channel 1821 can be discharged out through the supply port 1822 onto the cleaning component 150, and the cleaning component 150 is moistened to achieve wet mopping.

[0106] Please see Figure 17 The diagram shows a schematic representation of the liquid supply channel 1821 of the liquid supply unit 182 in some embodiments. The liquid supply channel 1821 of the liquid supply unit 182 includes an overflow channel 18211 and an outlet channel 18212, which are independent and not connected. The outlet 1832 of the first power unit 183 is connected to the outlet channel 18212, and the overflow port 1813 of the liquid storage unit 181 is connected to the overflow channel 18211. Since two or more liquid supply ports 1822 are provided in both the overflow channel 18211 and the outlet channel 18212, the total number of liquid supply ports 1822 in the entire liquid supply unit 182 is at least four. The liquid supply ports 1822 are spaced apart to enable multi-point liquid supply.

[0107] Please see Figure 17In some embodiments, both the overflow channel 18211 and the liquid outlet channel 18212 adopt an inlet section plus several outlet sections. In some embodiments, the outlet sections are connected to the inlet sections at the same location, and the flow path length from each liquid supply port 1822 to the connection point between the inlet section and the outlet section is the same. This ensures uniform distribution of liquid in each outlet section, allowing liquid in the channel to flow out evenly from each liquid supply port 1822.

[0108] The liquid supply section 182 can be a pipe or a flow channel plate, and this application is not limited thereto. In some embodiments, the liquid supply section 182 is a rigid structure. It is understood that a rigid structure is a structure that can maintain its shape and size without significant deformation when subjected to force. The liquid supply section 182 is made of rigid materials, such as plastic, carbon fiber, metal, glass, ceramics, etc. In contrast, there are flexible structures that will deform significantly when subjected to force, such as soft plastic tubing like silicone hoses or rubber hoses, or plastic tubing like straws.

[0109] Battery 130 can be a rechargeable battery or a non-rechargeable battery; this application makes no limitation. Please refer to [link / reference needed]. Figure 18 In some embodiments, when the battery 130 is a rechargeable battery, the cleaning device 100 may further include a charging component 118. The charging component 118 is electrically connected to the battery 130 for charging the battery 130. The charging component 118 may be a charging cable with a charging plug, such as a USB plug, Type-C connector, two-prong plug, three-prong plug, etc.; the charging component 118 may also be a conductive element, electrically connected to the battery 130 via a wire. In some embodiments, the charging component 118 is a metal sheet connected to the device body 110. The metal sheet is exposed relative to the device body 110.

[0111] In some embodiments, battery 130 is a rechargeable battery. Base station 200 includes base station body 210 and charging structure 220, with charging structure 220 installed in base station body 210. When cleaning device 100 enters base station 200, charging structure 220 charges battery 130 of cleaning device 100. Charging can be performed wirelessly or via wired charging; the specific charging method is not limited in this application.

[0112] In some embodiments, the battery 130 is a rechargeable battery, and the cleaning device 100 is provided with a charging component 118 made of a metal sheet, which is electrically connected to the battery 130. The charging component 118 is exposed relative to the device body 110, and the charging component 118 may bulge outward, be recessed inward, or be flush with the outer surface of the device body 110.

[0113] Please see Figure 20 In some embodiments, the base station 200 includes a base station body 210, a power supply module (not shown in the figure), and a charging structure 220. The base station body 210 serves as the mounting base, and both the power supply module and the charging structure 220 are mounted on the base station body 210. The charging structure 220 is electrically connected to the power supply module, which is used to conduct external power to the charging structure 220.

[0114] The base station 200 can be equipped with one or more charging structures 220. See also... Figure 20 In some embodiments, the base station 200 is provided with two charging structures 220, one serving as a positive power supply and the other as a negative power supply. The two charging structures 220 are symmetrically distributed on the base station body 210. The charging structures 220 can be located on the side or bottom of the base station 200, and the specific installation position is determined according to the position of the charging component 118 of the cleaning device 100.

[0115] The power supply module of base station 200 can be a battery capable of storing electrical energy. The battery can be a rechargeable battery or a primary battery, allowing base station 200 to be charged or its battery replaced periodically. The capacity of the battery in base station 200 can be greater than the capacity of the battery 130 in cleaning equipment 100, allowing base station 200 to power cleaning equipment 100 multiple times on a single charge. The power supply module can also include a transformer charger, converting external power into power that the device can input before connecting it to the charging structure 220. The power supply module can also be a power cord, serving only a conductive function. The specific structure of the power supply module is not limited in this application. The power supply module can be connected to the housing or to a mounting bracket; the specific installation location and method of the power supply module within the base station body 210 are not limited in this application.

[0116] Please see Figure 20 In some embodiments, at least a portion of the charging structure 220 is exposed relative to the base station body 210 to facilitate contact with the charging component 118 of the cleaning device 100. When the cleaning device 100 moves to the parking area of ​​the base station 200, the conductive contact portion can directly contact the charging component 118 on the side wall of the cleaning device 100. Of course, in other embodiments, the conductive contact portion may be flush with the outer surface of the base station body 210, or the conductive contact portion may be recessed relative to the base station body 210.

[0117] When the power level of the cleaning device 100 is lower than the set value, it automatically returns to the pile according to the instructions of the pile-finding module of the cleaning device 100. When the cleaning device 100 reaches the parking area, the charging component 118 presses the charging structure 220 forward, so that the charging structure 220 and the charging component 118 make conductive contact, and the base station 200 charges the battery 130 of the cleaning device 100.
