Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a cleaning device. Background Technology

[0002] With the development of intelligent cleaning technology, intelligent cleaning equipment is entering more and more places, greatly reducing the labor of cleaning.

[0003] Currently, cleaning equipment is not very effective, especially for stubborn stains, which cannot be removed well and require a lot of time to mop back and forth, resulting in low cleaning efficiency. Utility Model Content

[0004] The main purpose of this application is to provide a cleaning device to improve the cleaning effect and efficiency of the cleaning device.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a cleaning device, which includes a device body, a cleaning component, and a spraying component; the device body includes a drive component for driving the cleaning device forward; the cleaning component is disposed on the device body; the spraying component is disposed on one edge of the device body and avoids the cleaning component, and the spraying component is configured to spray cleaning material in a direction away from the cleaning component and away from the device body.

[0006] The beneficial effects of this application are as follows: The cleaning equipment provided by this application includes a main body, a cleaning component, and a spraying component. The main body is the main structure of the cleaning equipment, and the cleaning component is the part of the cleaning equipment used to clean the surface to be cleaned. When the main body moves, the main body drives the cleaning component to move on the surface to be cleaned, thereby achieving the cleaning component's cleaning of the surface to be cleaned. By setting the spraying component at the edge of the main body and spraying it towards the outside of the cleaning component, the cleaning substance can be directly applied to the area to be cleaned, avoiding interference from the spraying process to the cleaning component. The spraying component can pre-spray the cleaning substance onto the surface to be cleaned outside the cleaning component before the cleaning component cleans, effectively wetting and softening stubborn stains on the surface to be cleaned in advance, reducing the adhesion between the stubborn stains and the surface to be cleaned. The cleaning component then cleans the wetted and softened stains, making it easier to remove stubborn stains, improving the cleaning effect, reducing the number of repeated cleanings, and improving cleaning efficiency.

[0007] In some embodiments, the spraying assembly includes a nozzle seat and at least one nozzle core disposed on the nozzle seat. The nozzle seat has a channel cavity, which includes a communicating inlet and at least one outlet.

[0008] The spray assembly of this solution includes a nozzle seat and at least one nozzle core. The nozzle core is the core component for spraying the cleaning substance, and the nozzle seat is the mounting component for the nozzle core. The channel cavity inside the nozzle seat is used to allow the cleaning substance to flow. The channel cavity design of the nozzle seat allows the cleaning substance to flow from the inlet to each outlet, and then be sprayed out from the corresponding nozzle core at each outlet. The nozzle seat can be connected to an external water pipe, and the water inlet of each nozzle core is distributed by the channel cavity. Therefore, each nozzle core does not need to be connected to a separate water pipe, thus simplifying the external water pipe structure of the spray assembly.

[0009] In some embodiments, at least a portion of a nozzle core is embedded in a water outlet, and the nozzle core communicates with a channel cavity.

[0010] The nozzle seat and nozzle core of this solution adopt an embedded assembly structure, which makes the overall structure of the liquid spraying assembly more compact, reduces the overall height of the liquid spraying assembly, and helps to reduce the ground clearance of the nozzle core outlet.

[0011] In some embodiments, the device body has intersecting front-back and width directions, and the liquid spraying assembly is disposed at one end edge of the device body in the front-back direction; there are multiple nozzle cores, and the multiple nozzle cores are arranged at intervals along the width direction.

[0012] The lateral spacing of multiple nozzle cores in this design increases the coverage width of a single water spray.

[0013] In some embodiments, the axes of two adjacent nozzle cores are set at an angle; the distance between the axes of two adjacent nozzle cores gradually increases in the direction away from the main body of the device.

[0014] The angle between adjacent nozzle cores in this design allows the water spray range to expand laterally, creating a fan-shaped spray effect that distributes the water mist more evenly across the cleaning area. Furthermore, the axial spacing between adjacent nozzle cores increases progressively. This gradually expanding layout allows the water spray range to continuously expand as the equipment moves, avoiding the problem of concentrated water stains caused by fixed-point spraying.

[0015] In some embodiments, the included angle between the axes of two adjacent nozzle cores is 10 to 30 degrees. Exemplarily, the included angle between the axes of two adjacent nozzle cores can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees.

[0016] This embodiment limits the included angle between the axes of two adjacent nozzle cores to between 10 and 30 degrees, which can expand the appropriate water spray coverage area. Furthermore, the cleaning substances sprayed from the two adjacent nozzle cores can overlap each other, forming a more uniform spray surface on the surface to be cleaned. It can also reduce the risk of the cleaning substances sprayed from the nozzle cores onto the main body of the equipment.

[0017] In some embodiments, the angle between the axis of the nozzle core and the horizontal reference plane is 25 to 30 degrees; wherein the horizontal reference plane is a plane formed by the front-to-back direction and the width direction.

[0018] In this design, the nozzle core is tilted, allowing it to spray cleaning material onto the surface to be cleaned. The angle between the nozzle core's axis and the horizontal reference plane is limited to a specific range of 25 to 30 degrees. This makes it easier for the nozzle core to spray cleaning material onto the surface, resulting in a larger and more even coverage area as the device moves. This angle design ensures that the water spray direction and mopping path maintain the optimal working angle, allowing the water mist to penetrate stubborn stains more easily, thus improving the softening effect. It also reduces the risk of cleaning material spraying onto the device itself or other objects on the surface to be cleaned, such as furniture and walls.

[0019] In some embodiments, the device body has a height direction, the device body including a top and a bottom disposed opposite each other along the height direction; the vertical distance between the nozzle core outlet and the bottom is 15 mm to 24 mm.

[0020] In this solution, the vertical distance between the nozzle core outlet and the bottom is limited to a specific range of 15mm to 24mm. This allows the sprayed cleaning material to fully diffuse before reaching the ground, forming a more uniform wet area. This distance range avoids the cleaning material from dripping directly without being fully atomized due to the nozzle core being too low, and also prevents the water mist from dissipating too quickly due to the nozzle core being too high. In addition, this distance range makes the vertical distance between the nozzle core outlet and the surface to be cleaned smaller, so the cleaning material sprayed by the nozzle core is less likely to spray onto other objects on the surface to be cleaned, such as furniture and wall surfaces.

[0021] In some embodiments, the nozzle seat has a plurality of through surfaces corresponding to a plurality of nozzle cores, the through surfaces being located on the side of the outlet away from the inlet, and the through surfaces being perpendicular to the axis of the nozzle cores.

[0022] This structural design allows the cleaning material to be evenly distributed along the vertical direction of the penetrating surface after passing through the nozzle core. This ensures that the cleaning material forms a more stable spray angle when it is sprayed out, reducing the risk of the sprayed cleaning material being blocked by the penetrating surface.

[0023] In some embodiments, the spraying assembly further includes a seal that is fitted onto the nozzle seat and is sealingly connected between the device body and the nozzle seat.

[0024] The spraying assembly of this solution further includes a seal, which can improve the sealing performance between the equipment body and the nozzle seat, effectively preventing the cleaning material from seeping into the equipment body during the spraying process and causing short circuits or corrosion of mechanical parts.

[0025] In some embodiments, the device body has a front-rear direction, and the device body has a front part and a rear part arranged opposite to each other in the front-rear direction, with the liquid spraying assembly disposed at the rear part.

[0026] This solution places the spraying component at the rear of the main body of the equipment in the front-to-back direction, which can spray cleaning material towards the rear of the main body of the equipment as the main body moves forward, reducing the interference of the sprayed cleaning material on the main body of the equipment, especially reducing interference with components such as radar and cameras on the main body of the equipment.

[0027] In some embodiments, the device body has a top and a bottom disposed opposite each other in the height direction; the spraying assembly is located between the top and the bottom, and the spraying assembly is disposed closer to the bottom than the top.

[0028] In this design, the spraying assembly is positioned near the bottom of the main body of the equipment. This structure places the spraying assembly in the lower part of the main body of the equipment in terms of height, allowing it to operate closer to the ground during spraying. The sprayed cleaning material can directly act on the surface to be cleaned, reducing the risk of the cleaning material sprayed by the assembly hitting other objects on the surface to be cleaned. It also reduces the loss of cleaning material during the spraying process and improves spraying efficiency.

[0029] In some embodiments, the main body of the device includes a body portion and a walking wheel disposed on the body portion. In the height direction, the end of the body portion away from the walking wheel is the top, and the end of the walking wheel away from the body portion is the bottom. The body portion includes a base facing the bottom and a side panel located on the side of the base away from the bottom. A cleaning component is disposed on the base, and a spraying component is disposed on the base and / or the side panel.

[0030] In this solution, the main body of the equipment moves on the surface to be cleaned via wheels. The main body includes a base and side panels, which together form a storage space to accommodate other electronic components of the cleaning equipment. The base serves as the main support structure and can be used as a mounting support for the cleaning components. The spraying component sprays cleaning substances through the layout of the base or side panels. When the spraying component is placed on the base, its height from the ground is lower, making it less likely for the cleaning substances sprayed from the component to hit other objects on the surface to be cleaned, such as furniture or walls. When the spraying component is placed on the side panels, its height from the ground is relatively higher, which improves the mist dispersion effect and results in a larger and more even coverage area of ​​the cleaning substances on the surface to be cleaned.

[0031] In some embodiments, the base has a mounting protrusion facing downwards, the mounting protrusion avoids the cleaning component, and the spraying component is embedded in the mounting protrusion; the orthographic projection of the mounting protrusion on the base does not extend beyond the base.

[0032] In this solution, embedding the spraying component into the mounting protrusion lowers the height of the spraying component off the ground and reduces interference and impact of the spraying component on the internal components of the equipment. Furthermore, embedding the spraying component into the mounting protrusion reduces its exposure. The orthographic projection of the mounting protrusion onto the base does not extend beyond the base, which helps reduce the risk of the equipment getting stuck or accidentally hitting obstacles during movement.

[0033] In some embodiments, the device body has intersecting front-to-back and width directions, and the device body has a front part and a rear part arranged opposite to each other in the front-to-back direction, a spraying component is arranged in the rear part, a cleaning component is arranged near the rear part, and two cleaning components are arranged in the width direction; there is one spraying component, and the spraying component is located in the gap area formed by the two cleaning components; or, there are multiple spraying components arranged in the width direction.

[0034] The cleaning components in this solution are positioned near the rear, and the spraying components are located at the rear of the equipment body in the front-to-back direction. This allows the cleaning material to be sprayed towards the rear of the equipment body as it moves forward, reducing interference from the sprayed material on the equipment body, especially reducing interference with components such as radar and cameras on the equipment body. When there is only one spraying component, it is positioned in the gap area between the cleaning components, avoiding waste of cleaning material or spraying onto unclean areas, and ensuring that both cleaning components can remove stains from the sprayed area. When there are multiple spraying components along the width direction, the coverage area of ​​a single spray can be expanded, reducing the number of times the equipment body moves and improving the continuity of cleaning operations.

[0035] In some embodiments, the cleaning equipment further includes a water tank, a water pump, an inlet pipe, and an outlet pipe located within the main body of the equipment. The inlet pipe is connected between the water tank and the water pump, and the outlet pipe is connected between the water pump and the inlet.

[0036] The cleaning equipment in this solution further includes a water tank, a water pump, an inlet pipe, and an outlet pipe. The inlet pipe is used to connect the water tank and the water pump, and the outlet pipe is used to connect the water pump and the inlet of the nozzle seat. The water pump is used to draw out the cleaning material stored in the water tank and pump it into the nozzle seat. Then, the power of the water pump is used to make the cleaning material in the nozzle seat enter the nozzle core and spray it out from the nozzle core, which can make the cleaning material sprayed out by the nozzle core form a fine mist, thereby expanding the spraying area and spraying uniformity.

[0037] In some embodiments, the cleaning device further includes a stain detection mechanism and a main control board; the stain detection mechanism is used to identify stains; the main control board connects the stain detection mechanism and the spraying assembly, and the main control board is used to control the spraying assembly to spray cleaning material onto the stains according to the user's operation instructions or according to the stain identification results of the stain detection mechanism, and to control the cleaning assembly to work immediately after the spraying assembly sprays the cleaning material or after a preset time interval.

[0038] The spraying component of this solution has two activation mechanisms: it can be activated by user specification or by automatic detection by a stain detection agency. By spraying stubborn stains in a targeted manner before the cleaning component, the spraying component can effectively penetrate and soften the stain structure, making subsequent physical cleaning more efficient and reducing the number of cleaning cycles. The delay control function of the main control board allows the cleaning substance sufficient time to act on the stain, while avoiding liquid waste caused by spraying and cleaning actions occurring simultaneously.

[0095] With the development of smart cleaning technology, smart cleaning equipment is entering more and more places, greatly reducing the labor of cleaning. Currently, cleaning equipment typically involves directly sprinkling water onto the mop to wet it before mopping. The drawback of this method is that a wet mop is insufficient for cleaning stubborn, dried stains, resulting in poor cleaning effects, or the cleaning equipment needs to spend more time mopping back and forth to get the floor clean, leading to low efficiency.

[0096] Based on this, this application provides a cleaning device that can spray cleaning substances in advance through a spray component before the cleaning component removes stains, so as to moisten and soften stubborn stains on the surface to be cleaned, aiming to improve the cleaning effect of the cleaning device and reduce the number of times to mop back and forth, thereby improving cleaning efficiency.

[0097] The specific types of cleaning equipment involved in the embodiments of this application include, but are not limited to, cleaning robots. Specifically, they include, but are not limited to, mopping robots, floor washing robots, washing and mopping robots, sweeping and mopping robots, or sweeping and washing robots, etc., capable of cleaning surfaces to be cleaned while in motion, and suitable for various indoor and outdoor environments, such as indoor floors, outdoor roads, parks, hotels, stations, etc. The cleaning equipment may include cleaning components that can be used for washing or mopping, including, but not limited to, roller brushes or mops. More specifically, the cleaning components may include one or more of the following: rotary roller brushes, fluffy rollers, tracked mops, flat mops, and rotary disc mops.

[0098] In some embodiments, the cleaning equipment is described as an indoor mopping or floor washing device. During the operation of the cleaning equipment, as the cleaning equipment moves, the surface to be cleaned is cleaned by the rotation or movement of its cleaning components relative to the ground surface to be cleaned. For example, the roller brush can rotate relative to the surface to be cleaned and the main body of the cleaning equipment, and the mop can contact the surface to be cleaned and move along the surface to be cleaned to achieve cleaning.

[0099] The cleaning equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0100] Please see Figures 1 to 5 , Figure 1 This is a front view schematic diagram of an embodiment of the cleaning equipment provided in this application. Figure 2 yes Figure 1 A top-down view of the three-dimensional structure of the cleaning equipment. Figure 3 yes Figure 1 A three-dimensional structural diagram of the cleaning equipment viewed from below. Figure 4 yes Figure 1 A top view of the cleaning equipment. Figure 5 yes Figure 1The diagram shows a bottom view of the cleaning equipment 1, which includes a main body 10, a cleaning component 20, and a spraying component 30. The main body 10 includes a drive component for driving the cleaning equipment 1. The cleaning component 20 is disposed on the main body 10. The spraying component 30 is disposed on one edge of the main body 10 and avoids the cleaning component 20. The spraying component 30 is configured to spray cleaning material in a direction that is outside the cleaning component 20 and away from the main body 10.

[0101] The main body 10 serves as the main component of the cleaning device 1, housing the cleaning assembly 20, the spraying assembly 30, and other functional components of the cleaning device 1. A drive assembly on the main body 10 propels the cleaning device 1 forward. The main body 10 can be self-moving or controlled by an external remote control. Typically, to facilitate movement, wheels 120 are installed at the bottom of the main body 10. The main body 10 moves by rolling on the ground or cleaning surface using these wheels. The drive assembly propels the main body 10 forward by rotating the wheels 120. There can be two wheels 120, coaxial and spaced apart. As an example, the main body 10 also includes a main control board (not shown). The wheels are configured to execute directional commands from the main control board and guide the main body 10 forward when the cleaning device 1 performs its functions.

[0102] Generally, the main body 10 of the equipment has a front-to-back direction X. The cleaning device 1 moves along this direction. The main body 10 also includes a guide wheel 121. There can be one guide wheel 121, and the guide wheel 121 is located in front of the traveling wheels 120 in the front-to-back direction X of the main body 10. The guide wheel 121 and the two traveling wheels 120 are arranged in a triangle, so that the main body 10 can be placed stably and move on the surface to be cleaned. The two traveling wheels 120 are used as driving wheels, and the guide wheel 121 is used as driven wheels. The guide wheel can be a 360-degree omnidirectional wheel. The traveling wheels 120 are directional driving wheels, driven by a motor inside the main body 10. Straight movement or turning can be achieved by controlling the relative speed difference between the two traveling wheels 120.

[0103] The main body of the device 10 has a front and a rear that are opposite each other in the front-rear direction X. The front of the main body of the device 10 is usually equipped with components such as a camera, lidar, fill light, and signal light.

[0104] The cleaning component 20 is used to remove stains from the surface to be cleaned. The cleaning component 20 may include one or a combination of two or more of the following: a rotary brush, a fluff roller, a belt mop, a flat mop, and a rotary table mop. Figure 3 and Figure 5The cleaning component 20 is shown to have a disc mop structure, and there are two cleaning components 20 side by side. The disc mop can wipe the surface to be cleaned by rotating to achieve a mopping effect, thereby removing stains from the surface to be cleaned.

[0105] The spray assembly 30 is used to spray cleaning material onto the surface to be cleaned outside the cleaning assembly 20. The cleaning material can be, but is not limited to, water, cleaning liquid, or foam-like cleaning material. The spray assembly 30 is located at one edge of the device body 10. The spray assembly 30 can be completely exposed outside the device body 10, partially inside the device body 10 with the other part exposed, or completely inside the device body 10, as long as it can spray cleaning material onto the area outside the device body 10 while avoiding the cleaning assembly 20. When part of the spray assembly 30 is inside the device body 10 and the other part is exposed, an opening can be made in the wall of the device body 10 to allow the cleaning assembly 20 to be installed. When the spray assembly 30 is completely inside the device body 10, an opening can be made in the wall of the device body 10 so that the cleaning assembly 20 can spray cleaning material onto the outside of the device body 10 through the opening.

[0106] The cleaning device 1 provided in this application embodiment includes a device body 10, a cleaning component 20, and a spray component 30. The device body 10 is the main structure of the cleaning device 1, and the cleaning component 20 is a part of the cleaning device 1 used to clean the surface to be cleaned. When the device body 10 moves, the device body 10 drives the cleaning component 20 to move on the surface to be cleaned, thereby achieving the cleaning of the surface to be cleaned by the cleaning component 20. By setting the spray component 30 at the edge of the device body 10 and spraying the cleaning substance towards the outside of the cleaning component 20, the cleaning substance can be directly applied to the area to be cleaned, avoiding interference of the spraying process with the cleaning component 20. The spray component 30 can spray the cleaning substance on the surface to be cleaned outside the cleaning component 20 in advance before the cleaning component 20 cleans, effectively wetting and softening the stubborn stains on the surface to be cleaned in advance, reducing the adhesion between the stubborn stains and the surface to be cleaned. The cleaning component 20 then cleans the wetted and softened stains, making it easier to remove stubborn stains, improving the cleaning effect, reducing the number of repeated cleanings, and improving cleaning efficiency.

[0107] Please see Figures 6 to 11 , Figure 6 yes Figure 1 A three-dimensional structural schematic diagram of an embodiment of the liquid spraying component in a cleaning device. Figure 7 yes Figure 6 An exploded view of the liquid spraying assembly. Figure 8 yes Figure 6 A schematic diagram of the front view of the liquid spraying assembly. Figure 9 yes Figure 6A top-view plan view of the liquid spraying assembly. Figure 10 yes Figure 6 A side view of the liquid spraying assembly. Figure 11 yes Figure 10 A schematic diagram of the AA cross section of the spraying assembly. In some embodiments, the spraying assembly 30 includes a nozzle seat 31 and at least one nozzle core 32 disposed on the nozzle seat 31. The nozzle seat 31 is provided with a channel cavity 310, which includes a water inlet 310A and at least one water outlet 310B that are connected to each other.

[0108] In this embodiment, the spraying assembly 30 includes a nozzle seat 31 and at least one nozzle core 32. The nozzle core 32 is the main functional component for spraying the cleaning substance. The nozzle seat 31 serves as the mounting component for the nozzle core 32. Both the nozzle seat 31 and the nozzle core 32 can be made of corrosion-resistant and wear-resistant brass. The channel cavity 310 in the nozzle seat 31 is used to allow the flow of the cleaning substance. The channel cavity 310 of the nozzle seat 31 is designed so that the cleaning substance can flow from the inlet 310A to each outlet 310B, and then be sprayed out from the nozzle core 32 corresponding to each outlet 310B. The nozzle seat 31 can be connected to an external water pipe through the inlet 310A, and the water inlet of each nozzle core 32 can be distributed by the channel cavity 310. Therefore, each nozzle core 32 does not need to be connected to a separate water pipe, thereby simplifying the external water pipe structure of the spraying assembly 30.

[0109] In some embodiments, at least a portion of a nozzle core 32 is embedded in a water outlet 310B, and the nozzle core 32 is in communication with the channel cavity 310.

[0110] The nozzle seat 31 and nozzle core 32 adopt an embedded assembly structure, which makes the overall structure of the liquid spraying assembly 30 more compact, reduces the overall external size of the liquid spraying assembly 30, and helps to reduce the ground clearance of the nozzle core 32 outlet 320.

[0111] In this embodiment of the application, the nozzle core 32 in the spraying assembly 30 can be one, or two, three, four or more, that is, the spraying assembly 30 can be a single nozzle or a multi-nozzle.

[0112] In some embodiments, the nozzle core 32 can be an atomizing nozzle that can convert liquid cleaning substances into a mist or fine droplets and spray them evenly, thereby improving the dispersion effect of the cleaning substances and obtaining a larger spray area and a more uniform spray effect.

[0113] Atomizing nozzles can be broadly classified into mechanical atomizing nozzles and media atomizing nozzles based on their atomization methods. Mechanical atomization primarily relies on the high-speed jet generated by the liquid under pressure difference to atomize itself. Therefore, the nozzle core 32 can be divided into direct-fire atomizing nozzles, centrifugal atomizing nozzles, and rotary atomizing nozzles. Direct-fire atomization and centrifugal atomization can be collectively referred to as pressure atomization. Media atomizing nozzles mainly utilize air or other media (such as compressed air or steam) to form a high-speed airflow, creating a high relative velocity between the air and water to achieve atomization.

[0114] This application uses a direct-fire atomizing nozzle core 32 as an example for specific illustration. Please refer to [link to relevant documentation]. Figures 12 to 14 ,as well as Figures 15 to 16 , Figure 12 yes Figures 6 to 11 A three-dimensional structural diagram of the nozzle seat in the liquid spraying assembly. Figure 13 yes Figure 12 A side view of the nozzle seat structure. Figure 14 yes Figure 13 Schematic diagram of the BB section. Figure 15 yes Figures 6 to 11 A three-dimensional structural diagram of the nozzle core in the liquid spraying assembly. Figure 16 yes Figure 15 A three-dimensional structural diagram of the nozzle core from another perspective, as shown below. Figures 12 to 16 The mating structure of the nozzle seat 31 and the nozzle core 32, as well as the principle of how the nozzle core 32 atomizes the cleaning substance in the liquid, are explained in detail.

[0115] Specifically, the nozzle seat 31 includes a seat body 312 and a water inlet pipe 311. The seat body 312 and the water inlet pipe 311 are internally connected to form a channel cavity 310 for liquid to pass through. The water inlet pipe 311 is used to connect to an external water pipe to input cleaning substances into the channel cavity 310. The water inlet 310A of the channel cavity 310 is located at the end of the water inlet pipe 311 away from the seat body 312, and each water outlet 310B of the channel cavity 310 is located at the end of the seat body 312 away from the water inlet pipe 311.

[0116] The nozzle seat 31 also includes a protrusion 316 located in the outlet 310B. The outer peripheral surface of the protrusion 316 and the inner peripheral surface of the outlet 310B can both be cylindrical surfaces, and there is an annular gap between the outer peripheral surface of the protrusion 316 and the inner peripheral surface of the outlet 310B to form the outlet 310B.

[0117] The nozzle core 32 is a generally cylindrical groove structure. The inner circumferential surface of the nozzle core 32 includes multiple planes. The cylindrical outer circumferential surface of the protrusion 316 is tangent to each plane of the inner circumferential surface of the nozzle core 32. Therefore, the inner circumferential surface of the nozzle core 32 and the outer circumferential surface of the protrusion 316 can form multiple axial channels for the flow of cleaning substances for liquid. Each axial channel is connected to the outlet 320 of the nozzle core 32, and the outlet 320 of the nozzle core 32 is a hole with a very small diameter.

[0118] A high-pressure pump can be used to give the liquid cleaning substance a high liquid pressure, such as 2 to 20 MPa. The cleaning substance with a certain liquid pressure enters the channel cavity 310 from the inlet 310A, and after being diverted by each outlet 310B, it enters the corresponding nozzle core 32 in each outlet 310B. It flows through the axial channels formed between the nozzle core 32 and the protrusion 316, and finally is ejected from the outlet 320 of the nozzle core 32.

[0119] When a liquid is subjected to high pressure, its kinetic energy increases significantly. Once it passes through the extremely small orifice 320, the liquid is ejected at extremely high speed. During the ejection process, the surface tension, viscosity, and air resistance of the liquid interact with each other, causing the liquid to gradually change from a dripping state and a smooth flow state to a wavy flow state, and finally form a spray flow.

[0120] In some embodiments, the device body 10 has intersecting front-rear direction X and width direction Y. For example, the width direction Y can be perpendicular to the front-rear direction X. The liquid spraying assembly 30 is disposed at one end edge of the device body 10 in the front-rear direction X. There are multiple nozzle cores 32, and the multiple nozzle cores 32 are arranged at intervals along the width direction Y.

[0121] In this context, the axis R of the nozzle core 32 signifies that the nozzle core 32 can be a rotating structure with its own central axis. The flow direction of the cleaning material inside the nozzle core 32 is approximately along the axis of the nozzle core 32. The cleaning material enters from the inlet of the nozzle core 32 and exits from the outlet 320. In this application, the flow of the cleaning material within the nozzle core 32 along the axis R does not mean that the flow trajectory of the cleaning material within the nozzle core 32 is completely coincident with or parallel to the axis R of the nozzle core 32. Rather, it means that the flow trajectory of the cleaning material within the nozzle core 32 has at least a component in the axial direction of the nozzle core 32. The flow trajectory of the cleaning material within the nozzle core 32 can be any combination of one or more of the following: a straight line, a curve, and a broken line. The spray direction of the cleaning material ejected from the outlet 320 of the nozzle core 32 is also along the axis R of the nozzle core 32.

[0122] In some embodiments, the number of nozzle cores 32 in the spray assembly 30 may be two, three, four, or more. Figures 6 to 11 The case where there are two nozzle cores 32 is shown.

[0123] In this embodiment, multiple nozzle cores 32 are arranged along the width direction Y, and the lateral spacing of the multiple nozzle cores 32 expands the coverage width of a single water spray.

[0124] In some embodiments, the axes R of two adjacent nozzle cores 32 are set at an angle; the distance between the axes R of two adjacent nozzle cores 32 gradually increases in the direction away from the device body 10.

[0125] In this embodiment, the axes R of adjacent nozzle cores 32 form an angle α. The angle between adjacent nozzle cores 32 allows the water spray range to expand laterally, producing a fan-shaped spray effect. This makes the water mist more evenly distributed on the cleaning area of ​​the surface to be cleaned. Furthermore, when viewed along the front-back direction X, the axial spacing between adjacent nozzle cores 32 increases in the direction away from the main body 10 of the device. This gradually expanding layout allows the water spray range to continuously expand as the main body 10 of the device moves, avoiding the problem of concentrated water stains caused by fixed-point spraying.

[0126] In some embodiments, the included angle α between the axes R of two adjacent nozzle cores 32 is 10 degrees to 30 degrees. Exemplarily, the included angle α between the axes R of two adjacent nozzle cores 32 can be 10 degrees, 12 degrees, 14 degrees, 16 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, or 30 degrees. In a preferred embodiment, the included angle α between the axes R of two adjacent nozzle cores 32 can be 20 degrees.

[0127] In this design, the included angle of the axis R of adjacent nozzle cores 32 is used to control the water spray coverage range, thereby optimizing the distribution effect of water mist on the ground. If the included angle α between the axes R of two adjacent nozzle cores 32 is too small (e.g., less than 10 degrees), the coverage area of ​​the cleaning material sprayed by the two adjacent nozzle cores 32 on the surface to be cleaned will be too small. If the included angle α between the axes R of two adjacent nozzle cores 32 is too large (e.g., less than 30 degrees), the overlap of the coverage area of ​​the cleaning material sprayed by the two adjacent nozzle cores 32 on the surface to be cleaned will be too small, and the coverage shape formed on the surface to be cleaned will be irregular. As the main body 10 of the equipment moves, the coverage of the cleaning material on the surface to be cleaned will be poor, and the cleaning material sprayed by the nozzle cores 32 will easily spray onto the main body 10 of the equipment.

[0128] In this embodiment, the included angle α between the axes R of two adjacent nozzle cores 32 is limited to between 10 degrees and 30 degrees, which can expand the appropriate water spray coverage area. Furthermore, the water mist cleaning material sprayed by the two adjacent nozzle cores 32 can overlap with each other, forming a more uniform spray surface on the surface to be cleaned. It can also reduce the risk of the cleaning material sprayed by the nozzle cores 32 spraying onto the main body 10 of the equipment.

[0129] When the spray assembly 30 has multiple nozzle cores 32, the arrangement of each nozzle core 32 can be varied. As one example, the nozzle cores 32 can be arranged linearly along the width direction Y; as another example, the nozzle cores 32 can also be arranged in a rectangular array or a circular array to achieve a more uniform spraying effect. When the spray assembly 30 adopts... Figures 6 to 11 When two nozzle cores 32 are used, the two nozzle cores 32 can be arranged side by side along the width direction Y, and the two nozzle cores 32 can be at the same height position in the height direction Z of the cleaning device 1, or they can be staggered along the height direction Z. Among them, the height direction Z of the cleaning device 1 can intersect with the front-back direction X and the width direction Y in pairs, for example, they can be perpendicular to each other. When the cleaning device 1 is moving on the ground waiting to be cleaned, the height direction Z can be a direction perpendicular to the surface to be cleaned.

[0130] In some embodiments, the angle between the axis R of the nozzle core 32 and the horizontal reference plane is 25 to 35 degrees; wherein the horizontal reference plane is a plane formed by the front-to-back direction X and the width direction Y. Exemplarily, the angle between the axis R of the nozzle core 32 and the horizontal reference plane can be 25 degrees, 28 degrees, 30 degrees, 32 degrees, or 35 degrees. In a preferred embodiment, the angle between the axis R of the nozzle core 32 and the horizontal reference plane can be 30 degrees.

[0131] When the main body 10 of the device moves on the surface to be cleaned, the horizontal reference plane can be regarded as a reference plane parallel to the surface to be cleaned.

[0132] In this design, the nozzle core 32 is tilted, allowing it to spray cleaning material downwards toward the surface to be cleaned. If the angle β between the axis R of the nozzle core 32 and the horizontal reference plane is too large, the cleaning material sprayed by the nozzle core 32 will not spread well on the surface to be cleaned. If the angle β between the axis R of the nozzle core 32 and the horizontal reference plane is too small, it will increase the risk of the cleaning material sprayed by the nozzle core 32 hitting other objects on the surface to be cleaned, such as furniture and walls.

[0133] In this embodiment, the angle β between the axis R of the nozzle core 32 and the horizontal reference plane is limited to a specific range of 25 degrees to 35 degrees. The nozzle core 32 can more easily spray cleaning material onto the surface to be cleaned, and the sprayed water mist can form a larger and more uniform coverage area during the movement of the device body 10. This angle design can ensure that the water spray direction and the mopping path maintain the optimal working angle, making it easier for the water mist to penetrate into stubborn stains, thereby improving the softening effect. At the same time, it can reduce the risk of cleaning material being sprayed onto the device body 10 itself and other objects sprayed on the surface to be cleaned, such as furniture, walls and other surfaces.

[0134] In some embodiments, the device body 10 has a height direction Z intersecting the front-rear direction X, and the device body 10 includes a top and a bottom disposed opposite each other along the height direction Z; the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 is 15 mm to 24 mm. Exemplarily, the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 can be 15 mm, 18 mm, 20 mm, 22 mm, or 24 mm. In a preferred embodiment, the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 is 20 mm.

[0135] The height direction Z of the cleaning device 1 can be perpendicular to the front-to-back direction X and the width direction Y. When the cleaning device 1 is moving on the ground waiting to be cleaned, the height direction Z can be perpendicular to the surface to be cleaned. The bottom of the device body 10 is the side closer to the surface to be cleaned in the height direction Z, and conversely, the top of the device body 10 is the side farther away from the surface to be cleaned in the height direction Z. Specifically, the bottom of the device body 10 refers to the position where the device body 10 contacts the surface to be cleaned.

[0136] The vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the equipment body 10 refers to the vertical distance in the height direction Z, that is, the vertical distance H between the outlet 320 of the nozzle core 32 and the surface to be cleaned when the equipment body 10 moves on the surface to be cleaned.

[0137] When the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 is too small (e.g., less than 15 mm), the cleaning material sprayed from the outlet 320 of the nozzle core 32 will not diffuse sufficiently before reaching the surface to be cleaned, resulting in a small and uneven coverage area of ​​the cleaning material on the surface to be cleaned. When the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 is too large (e.g., greater than 24 mm), the water mist sprayed from the outlet 320 of the nozzle core 32 will dissipate too much in the air.

[0138] In this embodiment, the vertical distance H between the outlet 320 of the nozzle core 32 and the bottom of the device body 10 is limited to a specific range of 15mm to 24mm. This allows the sprayed cleaning material to fully diffuse before reaching the ground, forming a larger and more uniform wet area. This distance range avoids the cleaning material from dripping directly without being fully atomized due to the nozzle core 32 being too low, and also prevents the water mist from dissipating too quickly due to the nozzle core 32 being too high. Furthermore, this distance range ensures that the vertical distance between the outlet 320 of the nozzle core 32 and the surface to be cleaned is within a small range, making it less likely for the cleaning material sprayed by the nozzle core 32 to spray onto other objects on the surface to be cleaned, such as furniture or walls.

[0139] In some embodiments, the nozzle seat 31 has a plurality of through surfaces 3120 corresponding to a plurality of nozzle cores 32. The through surfaces 3120 are located on the side of the outlet 310B away from the inlet 310A, and the through surfaces 3120 are perpendicular to the axis R of the nozzle cores 32.

[0140] The through surface 3120 can be the surface of the seat 312 away from the main body 10 in the front-rear direction X. The nozzle core 32 is housed in the corresponding outlet 310B. The nozzle core 32 can be flush with the through surface 3120 or protrude from the through surface 3120. The height of the protrusion from the through surface 3120 should be designed to be small enough to avoid excessive exposure of the nozzle core 32. Alternatively, the nozzle core 32 can be recessed relative to the through surface 3120.

[0141] In this embodiment, the through surface 3120 is perpendicular to the axis R of the nozzle core 32. This structural design allows the cleaning material to be evenly distributed along the vertical direction of the through surface 3120 after passing through the nozzle core 32, ensuring a more stable spray angle when the cleaning material is sprayed out and reducing the risk of the sprayed cleaning material being blocked by the through surface. Of course, this application does not exclude the possibility that the through surface 3120 is inclined relative to the axis R of the nozzle core 32.

[0142] When the nozzle core 32 of the spray assembly 30 in this application embodiment is Figures 6 to 11 When the two nozzle cores 32 are arranged at an angle as shown, correspondingly, there are also two through surfaces 3120 on the nozzle seat 31 of the liquid spraying assembly 30, and the two through surfaces 3120 are also arranged at an angle.

[0143] In some embodiments, see again Figure 6 and Figure 7 The spraying assembly 30 also includes a seal 33, which is sleeved on the nozzle seat 31 and is sealed between the equipment body 10 and the nozzle seat 31.

[0144] The spraying assembly 30 of this solution further includes a seal 33, which can improve the sealing performance between the main body 10 and the nozzle seat 31, and effectively prevent the cleaning material from seeping into the interior of the main body 10 during the spraying process, causing short circuits or corrosion of mechanical parts.

[0145] Specifically, the housing of the device body 10 has a through hole, and the seat 312 of the nozzle seat 31 extends from the inside of the device body 10 through the through hole, so that a part of the seat 312 is exposed outside the device body 10, so that the nozzle core 32 can spray cleaning material. The nozzle seat 31 also includes an abutment ring 315, which is located inside the device body 10. The sealing member 33 can be sleeved on the seat 312 and is located inside the device body 10. The sealing member 33 abuts against the abutment ring 315 and the inner wall of the device body 10, thereby achieving a seal between the nozzle seat 31 and the device body 10. The sealing member 33 can also be snapped into the through hole on the housing of the device body 10 to achieve a seal between the nozzle seat 31 and the device body 10.

[0146] In some embodiments, the nozzle seat 31 further includes a nozzle mounting plate 313. The nozzle mounting plate 313 can be disposed on both sides of the seat body 312 in the width direction Y of the device body 10. The nozzle mounting plate 313 is used to realize the connection and fixation between the nozzle seat 31 and the device body 10. Specifically, the nozzle mounting plate 313 is provided with fixing holes. Fasteners such as bolts are passed through the fixing holes on the nozzle mounting plate 313 and locked to the device body 10. More specifically, it can be locked to the base 111 described below to realize the connection and fixation between the nozzle seat 31 and the device body 10.

[0147] In some embodiments, the nozzle seat 31 further includes a reinforcing portion 314 disposed on the outer surface of the seat body 312 to enhance the structural strength of the seat body 312 and reduce the risk of deformation of the seat body 312.

[0148] In some embodiments, the device body 10 has a front portion and a rear portion disposed opposite each other in the front-rear direction X, and the liquid spraying assembly 30 is disposed on at least one of the front portion and the rear portion.

[0149] The front part of the main body 10 is the side in front of the cleaning equipment 1 when it moves, and the rear part of the main body 10 is the side behind the cleaning equipment 1 when it moves.

[0150] The spraying assembly 30 can be located only at the rear, only at the front, or both at the front and rear.

[0151] By positioning the spraying component 30 on one or both edges in the front-to-back direction, cleaning agents can be sprayed onto stubborn stains during the back-to-back movement of the main body of the device, improving the accuracy of spraying cleaning agents onto stubborn stains.

[0152] In other embodiments, the spraying assembly 30 may also be disposed at the edge in the width direction.

[0153] In some embodiments, the spraying assembly 30 is disposed at the rear of the device body 10.

[0154] In this design, the spraying assembly 30 is positioned at the rear of the device body 10 in the front-to-back direction X. Since the front of the device body 10 typically houses components such as cameras, this design reduces interference from the cleaning material sprayed by the spraying assembly 30 on these components. In some embodiments, the device body 10 has a top and a bottom that are positioned opposite each other in the height direction Z; the spraying assembly 30 is located between the top and the bottom, and is positioned closer to the bottom than the top.

[0155] In this design, the spraying assembly 30 is positioned close to the bottom of the main body 10. This structure places the spraying assembly 30 in the lower region of the main body 10 in the height direction Z, allowing it to be closer to the ground and wait for the surface to be cleaned during spraying. The sprayed cleaning material can directly act on the surface to be cleaned, reducing the risk of the cleaning material sprayed by the spraying assembly 30 hitting the surface of other objects on the surface to be cleaned. It also reduces the loss of cleaning material during the spraying process and improves spraying efficiency.

[0156] In some embodiments, the device body 10 includes a body portion 110 and a traveling wheel 120 disposed on the body portion 110. In the height direction Z of the device body 10, the end of the body portion 110 away from the traveling wheel 120 is the top of the device body 10, and the end of the traveling wheel 120 away from the body portion 110 is the bottom of the device body 10. The body portion 110 includes a base 111 facing the bottom of the device body 10 and a side panel 112 located on the side of the base 111 away from the bottom of the device body 10. The cleaning component 20 is disposed on the base 111, and the spraying component 30 is disposed on the base 111 and / or the side panel 112.

[0157] The base 111 serves as the mounting support for the wheels 120 and the cleaning assembly 20. The base 111 can be a plate-like structure, with side panels 112 surrounding its perimeter. The wheels 120 are typically located in the center of the main body 10 in the front-rear direction X. In some embodiments, the wheels 120 may pass through the base 111, meaning a portion of the wheels 120 is located within the receiving space formed by the base 111 and the side panels 112, while another portion is located outside this space. The motor driving the wheels 120 is arranged within the receiving space formed by the base 111 and the side panels 112. In other embodiments, the base 111 may be recessed corresponding to the position of the wheels 120, with the wheels 120 positioned at this recessed location. The end of the wheels 120 furthest from the base 111 forms the bottom of the main body 10.

[0158] In some embodiments, the device body 10 further includes a top plate located at the end of the side panel 112 away from the base 111. The base 111, the side panel 112 and the top plate together constitute the shell structure of the device body 10.

[0159] In this solution, the main body 10 of the equipment moves on the surface to be cleaned via wheels 120. The main body 10 includes a base 111 and a side panel 112. The base 111 and the side panel 112 together form a receiving space to accommodate other parts of the cleaning equipment 1. The base 111 serves as the main support structure and can be used as a mounting support for the wheels 120 and the cleaning component 20. The spraying component 30 sprays cleaning materials through the arrangement of the base 111 or the side panel 112. When the spraying component 30 is set on the base 111, the spraying component 30 is lower off the ground, and the cleaning material sprayed by the spraying component 30 is less likely to spray onto other objects on the surface to be cleaned, such as furniture or walls. When the spraying component 30 is set on the side panel 112, the spraying component 30 is relatively higher off the ground, and the cleaning material sprayed by the spraying component 30 can improve the water mist dispersion effect, resulting in a larger and more uniform coverage area of ​​the cleaning material on the surface to be cleaned.

[0160] The spraying component 30 can be installed separately on the base 111, separately on the side panel 112, or simultaneously on the side panel 112.

[0161] Please see Figure 17 , Figure 17 yes Figure 3 The enlarged view of the cleaning equipment at the spray component shows that in some embodiments, the base 111 has a mounting protrusion 1111 facing the bottom of the equipment body 10, which is also facing the walking wheel 120. The mounting protrusion 1111 avoids the cleaning component 20, and the spray component 30 is embedded in the mounting protrusion 1111. The orthographic projection of the mounting protrusion 1111 on the base 111 does not exceed the base 111.

[0162] In this design, embedding the spraying component 30 into the mounting protrusion 1111 reduces the ground clearance of the spraying component 30 and also reduces interference and impact of the spraying component 30 on the internal components of the main body 10, thus reducing the space occupied inside the main body 10. Furthermore, embedding the spraying component 30 into the mounting protrusion 1111 reduces the exposure of the spraying component 30. The orthogonal projection of the mounting protrusion 1111 onto the base 111 does not exceed the base 111, which helps reduce the risk of the main body 10 getting stuck or accidentally hitting obstacles during movement.

[0163] In some embodiments, the mounting protrusion 1111 is also provided with an auxiliary wheel 122. The main body 10 of the device moves on the surface to be cleaned by the walking wheel 120, the guide wheel 121 and the auxiliary wheel 122. On the one hand, this can improve the stability of the main body 10 when it moves, and on the other hand, it can reduce the risk of friction between the mounting protrusion 1111 and the surface to be cleaned caused by the mounting protrusion 1111 directly contacting the surface to be cleaned.

[0164] In some embodiments, the device body 10 has a width direction Y intersecting the front-rear direction X, and the device body 10 has a front part and a rear part arranged opposite to each other along the front-rear direction X. The spraying assembly 30 is disposed at the rear part of the device body 10, and the cleaning assembly 20 is disposed near the rear part of the device body 10, and two cleaning assemblies 20 are disposed along the width direction Y; the spraying assembly 30 is one, and the spraying assembly 30 is located in the gap area formed by the two cleaning assemblies 20; or, multiple spraying assemblies 30 are disposed along the width direction Y.

[0165] In this design, the cleaning component 20 is positioned near the rear, and the spraying component 30 is located at the rear of the main body 10 in the front-rear direction X. This allows the cleaning material to be sprayed towards the rear of the main body 10 as it moves forward, reducing interference from the sprayed material, especially from components such as radar and cameras at the front of the main body 10. When there is only one spraying component 30, it is positioned in the gap between two cleaning components 20, preventing waste of cleaning material or spraying onto unclean areas. This also ensures that both cleaning components 20 can clean the area sprayed by the spraying component 30. When there are multiple spraying components 30 along the width direction Y, the coverage area of ​​a single spray can be expanded, reducing the number of times the main body 10 moves and improving the continuity of the cleaning operation.

[0166] Please see Figure 18 , Figure 18 yes Figure 1 The internal three-dimensional structure of the cleaning device 1 is shown in some embodiments. The cleaning device 1 also includes a water tank 41, a water pump 42, an inlet pipe 43 and an outlet pipe 44 located in the main body 10 of the device. The inlet pipe 43 is connected between the water tank 41 and the water pump 42, and the outlet pipe 44 is connected between the water pump 42 and the inlet 310A of the nozzle seat 31.

[0167] The cleaning equipment 1 of this solution further includes a water tank 41, a water pump 42, an inlet pipe 43, and an outlet pipe 44. The water tank 41 is used to store cleaning materials. The water pump 42 draws cleaning materials from the water tank 41 through the inlet pipe 43 and then delivers them to the inlet 310A of the nozzle seat 31 through the outlet pipe 44. The inlet pipe 43 forms a communication path with the water tank 41 and the water pump 42. The outlet pipe 44 connects the water pump 42 to the inlet 310A of the nozzle seat 31, ensuring the continuity of the cleaning material flow. Furthermore, the water pump 42 can provide high liquid pressure for the liquid cleaning material, thereby enabling the liquid cleaning material to be sprayed out through the outlet 320 of the nozzle core 32 to form a fine mist, thereby expanding the spraying area and spray uniformity.

[0168] In some embodiments, the liquid cleaning substance stored in the water tank 41 can also be delivered to the cleaning component 20 to wet the cleaning component 20 itself. When the cleaning component 20 is wetted, it is more effective at removing stains when mopping the floor.

[0169] In some embodiments, the cleaning device 1 further includes a stain detection mechanism (not shown) and a main control board (not shown); the stain detection mechanism is used to identify stains; the main control board connects the stain detection mechanism and the spray assembly 30, and the main control board is used to control the spray assembly 30 to spray cleaning material onto the stains according to the user's operation instructions or according to the stain identification results of the stain detection mechanism, and to control the cleaning assembly 20 to work immediately after the spray assembly 30 sprays the cleaning material or after a preset time interval.

[0170] The stain detection mechanism can be a camera. The camera takes pictures of the surface to be cleaned and transmits the images to the main control board. The main control board analyzes the images to identify stains. Specifically, it can identify whether the stain is a stubborn stain. When a stubborn stain is identified, the main control board controls the spray component 30 to spray cleaning material onto the stubborn stain to moisten and soften it. After the spray component 30 sprays the cleaning material, it immediately controls the cleaning component 20 to work, which can shorten the cleaning time. After a certain preset interval, the cleaning component 20 removes the stain, which provides a certain waiting time for the stubborn stain to soften, thus improving the cleaning effect of the cleaning component 20.

[0171] The spraying component 30 of this solution has two activation mechanisms for spraying. It can be activated by user specification or by automatic detection by a stain detection mechanism. By spraying stubborn stains in a targeted manner before cleaning by the cleaning component 20, the spraying component 30 can effectively penetrate and soften the stains, making subsequent physical cleaning more efficient and reducing the number of cleaning cycles. The delay control function of the main control board allows the cleaning substance sufficient time to act on the stains, while avoiding liquid waste caused by spraying and cleaning actions occurring simultaneously.

[0172] When the main control board controls the spraying component 30 to spray cleaning material according to the user's operation instructions, the user can specify a cleaning area. The cleaning device 1 travels in the specified cleaning area along a predetermined planned path, while the spraying component 30 sprays cleaning material once. During this period, the cleaning component 20 does not mop the floor. After the spraying component 30 finishes spraying the cleaning material, the cleaning device 1 returns to the original path and travels again in the specified cleaning area along the predetermined planned path. At the same time, the cleaning component 20 mops the floor to remove stains. During this period, the spraying component 30 does not spray cleaning material.

[0173] Generally, when a stain detection mechanism is used to automatically detect stubborn stains and activate the spray component 30, the stain detection mechanism, such as the camera, and the spray component 30 are located on opposite sides of the main body 10. For example, the camera is located at the front of the main body 10 in the front-to-back direction, and the spray component 30 is located at the rear of the main body 10 in the front-to-back direction. When the camera detects a stubborn stain, the main body 10 can be rotated 180 degrees, causing the camera and the spray component 30 to turn around. In this way, after the camera detects a stubborn stain, the spray component 30 can be precisely aimed at the stubborn stain and spray the cleaning substance accurately onto it. Of course, this application is not limited to the solution of rotating the main body 10 of the device by 180 degrees. The rotation angle of the main body 10 of the device can be adaptively changed according to the relative position of the camera and the spraying component 30. As long as the camera can detect stubborn stains, the main body 10 of the device can be rotated in place by a certain angle so that the spraying component 30 is exactly in the original position of the camera, the spraying component 30 can accurately spray cleaning substances onto the stubborn stains.

[0174] By using the method of user-specified spray area to start the spraying of the liquid spraying component 30, when the main body of the equipment 10 is moving forward normally, the liquid spraying component 30 only needs to spray the cleaning material backward. This is a large-area spraying, so there is no need to turn the camera and the liquid spraying component 30 around.
