Description

Technical Field

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

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that use artificial intelligence to automatically clean floors in a room. The mop in these devices can wet-clean the floor, and it can swing relative to the casing to reduce cleaning dead spots and improve cleaning effectiveness.

[0003] In existing technologies, when a mop is used for wet cleaning of the floor, the cleaning equipment draws external liquid into a water tank, and then continuously sprays the liquid (such as clean water or water with detergent added) from the tank onto the mop through a water outlet pipe to soak it. However, the current technology results in a slow soaking rate for the mop, leading to low cleaning efficiency and negatively impacting the user experience. Utility Model Content

[0004] The main objective of this application is to provide a cleaning device to solve the problem of slow liquid-soaked mops mentioned in the background art.

[0005] According to one aspect of this application, a cleaning device is provided, comprising:

[0006] main body;

[0007] The cleaning component includes at least two sets, each set of which is located at the bottom of the main body, and each cleaning component is provided with a flow guiding structure.

[0008] A water supply assembly, comprising a water tank and a water supply component, both of which are located on the main body. The water supply component includes an inlet and at least two outlets. The inlet is connected to the water tank. Along the height of the main body, at least two outlets are located at the bottom of the main body and are respectively connected to and correspond to the flow guiding structures of at least two sets of the cleaning components.

[0009] The inlet has a first cross-section along its width direction, the area of ​​the first cross-section being S1, and the outlet has a second cross-section along its width direction, the area of ​​the second cross-section being S2. The sum of the S2 values ​​of at least two outlets is Y, and Y and S1 satisfy the relationship: Y < S1.

[0010] Furthermore, the water supply component also includes:

[0011] A water supply channel is provided with a connecting port, which is connected to the water inlet. At least two water outlets are connected to the connecting port. The distance between the water outlet and the connecting port is L, and the distance L for at least two water outlets is equal.

[0012] Furthermore, the water supply channel includes an inlet channel and at least two outlet channels. The inlet channel is connected to the inlet. The at least two outlet channels are respectively located on opposite sides of the connecting opening and are both connected to the connecting opening. At least two outlets are correspondingly located to the at least two outlet channels and are respectively located on the side of the at least two outlet channels away from each other. The at least two outlet channels are straight channels, and the cross-sectional areas of the at least two outlet channels along the height direction of the main body are equal.

[0013] Furthermore, the areas of the second cross-section of at least two of the outlets are equal.

[0014] Furthermore, the area S1 of the first cross-section satisfies the relationship: 5mm≤S≤11mm.

[0015] Furthermore, the area S2 of the second cross section satisfies the relationship: 0.8mm≤S≤3.5mm.

[0016] Furthermore, the water tank is provided with a storage chamber, an overflow chamber, and a second overflow port. The second overflow port is located on the side wall of the overflow chamber to connect the storage chamber and the overflow chamber. The bottom of the main body is also provided with a first overflow port, which is connected to the overflow chamber. Along the height direction of the main body, there is a first height between the second overflow port and the bottom of the storage chamber. When the water level in the water tank is higher than the first height, the first overflow port is used to discharge water exceeding the first height. The maximum width of the first overflow port is greater than the maximum width of the outlet.

[0017] Furthermore, the water tank is provided with a water injection hole, the maximum width of which is less than the maximum width of the first overflow port.

[0018] Alternatively, the maximum width of the water injection hole is greater than the maximum width of the first overflow port.

[0019] Furthermore, the cleaning component has a first projection area at the bottom of the main body, the first projection area being offset from the first overflow port.

[0020] Furthermore, the maximum width of the first overflow port is D, and D satisfies the relationship: 2mm≤D≤3mm.

[0021] Furthermore, at least one set of the cleaning components has an inward-retracted state and an outward-expanded state, and along the height direction of the main body, the water outlet is at least partially disposed opposite to the flow guiding structure;

[0022] In the inward state, the flow guiding structure has a first projected outer contour on the body along the height direction of the main body; in the outward state, the flow guiding structure has a second projected outer contour on the body along the height direction of the main body; and the outlet is at least partially located within the overlapping area of ​​the first projected outer contour and the second projected outer contour.

[0023] Furthermore, at least one set of the cleaning components has an inward retracted state and an outward expanding state, and the water supply component further includes:

[0024] A liquid outlet is disposed between the main body and the flow guiding structure. The liquid outlet can move relative to the main body as the cleaning component moves. At least one water outlet is disposed on the liquid outlet.

[0025] Furthermore, the main body includes a top shell and a bottom shell. The bottom shell is disposed at the bottom of the top shell and surrounds the top shell to form an installation space. The water tank is disposed within the installation space. The water supply component includes a cover plate. The cover plate covers the bottom shell on the side near the top shell and surrounds the bottom shell to form the water supply channel. The water inlet is disposed on the cover plate.

[0026] Furthermore, the water supply assembly also includes a connecting member and a connecting pipe. The connecting member is disposed at the bottom of the main body and communicates with the water outlet. One end of the connecting pipe is communicated with the water inlet, and the other end of the connecting pipe is communicated with the connecting member.

[0027] Furthermore, at least one of the water outlets is configured to correspond to at least two sets of the cleaning components.

[0028] Furthermore, at least two of the water outlets are configured in a one-to-one correspondence with at least two sets of the cleaning components.

[0029] Furthermore, at least one set of the cleaning components is provided corresponding to at least two of the water outlets.

[0030] In this application, the liquid in the water tank can flow into the inlet and then out of the outlet into the guide structure. The sum of the areas of the second cross-sections of at least two outlets is less than the area of ​​the first cross-section of the outlet. When the liquid flow rate of the water supply component remains constant, the total cross-sectional area of ​​the outlet decreases, the liquid flow rate increases, and the liquid in the water tank can flow into the guide structure more quickly through the outlet. The liquid can more quickly wet the cleaning component, improving the cleaning efficiency of the cleaning component and providing a better user experience. Attached Figure Description

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0049] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0050] like Figures 1 to 13As shown, this application provides a cleaning device. The cleaning device includes a main body 10, a cleaning assembly 20, and a water supply assembly. The cleaning assembly 20 includes at least two sets, each set located at the bottom of the main body 10, and each cleaning assembly 20 is provided with a flow guiding structure 21. The water supply assembly includes a water tank 31 and a water supply component 32. Both the water tank 31 and the water supply component 32 are located on the main body 10. The water supply component 32 includes an inlet 321 and at least two outlets 322. The inlet 321 communicates with the water tank 31 and extends along the height direction of the main body 10 (e.g., along the bottom of the main body 10). Figure 1 (In the direction indicated by the middle arrow X), at least two water outlets 322 are located at the bottom of the main body 10 and are respectively connected to the flow guiding structures 21 of at least two sets of cleaning components 20. The water inlet 321 has a first cross-section along its own width direction with an area of ​​S1, and the water outlet 322 has a second cross-section along its own width direction with an area of ​​S2. The sum of S2 of at least two water outlets 322 is Y, and Y and S1 satisfy the relationship: Y < S1.

[0051] In this embodiment, the liquid in the water tank 31 flows into the inlet 321 and then out through the outlet 322 into the guide structure 21. The sum of the cross-sectional areas of all outlets 322 is less than the cross-sectional area of ​​the inlet 321. According to Bernoulli's principle, when the liquid flow rate of the water supply component remains constant, the sum of the cross-sectional areas of the outlets 322 decreases, the liquid velocity increases, and the liquid in the water tank 31 can flow into the guide structure 21 more quickly through the outlets 322. The liquid can more quickly wet the cleaning component 20, improving the cleaning efficiency of the cleaning component 20 and providing a better user experience. If Y≥S1, the sum of the cross-sectional areas of all outlets 322 is greater than or equal to the cross-sectional area of ​​the inlet 321. When the liquid flow rate of the water supply component remains constant, the total cross-sectional area of ​​the outlets 322 increases, and the liquid velocity decreases. This leads to a decrease in the speed at which the liquid wets the cleaning component 20, a slower water replenishment speed for the cleaning component 20, and lower cleaning efficiency of the cleaning equipment.

[0052] like Figures 1 to 2As shown, the flow guiding structure 21 includes multiple first through holes 211. The cleaning assembly 20 includes a tray 22 and a flexible cleaning element 23. Multiple first through holes 211 are disposed through the tray 22 along the height direction of the main body 10 and are spaced apart circumferentially along the tray 22. The flexible cleaning element 23 is laid on the surface of the tray 22 away from the main body 10. Liquid flowing from the outlet 322 can pass through the first through holes 211 to the flexible cleaning element 23 and wet it, allowing the flexible cleaning element 23 to contact the ground for wet cleaning. The sum of the values ​​of S2 from at least two outlets 322 is less than the area of ​​the first cross-section of the outlet 322, allowing liquid to flow out of the outlet 322 more quickly, pass through the first through holes 211, and fall onto the flexible cleaning element 23. This allows the flexible cleaning element 23 to be wetted more quickly, accelerating the water replenishment speed of the flexible cleaning element 23 and improving the cleaning efficiency of the cleaning equipment. The flexible cleaning component 23 includes mops, cleaning brushes, etc., but this embodiment does not limit it to a single component.

[0053] The outlet 322 and the inlet 321 can be configured as circular holes, square holes, trapezoidal holes, or irregularly shaped holes.

[0054] In one embodiment, the water supply component 32 further includes a water supply channel 323, which has a connecting port 3233 connected to the water inlet 321. At least two water outlets 322 are connected to the connecting port 3233, and the distance between the water outlets 322 and the connecting port 3233 is L. The distance L between the at least two water outlets 322 is equal.

[0055] The water supply channel 323 includes an inlet channel 3231 and at least two outlet channels 3232. The inlet channel 3231 is connected to the inlet 321. The at least two outlet channels 3232 are respectively located on opposite sides of the connecting port 3233 and are both connected to the connecting port 3233. At least two outlets 322 are correspondingly located to the at least two outlet channels 3232 and are respectively located on the side of the at least two outlet channels 3232 away from each other. The at least two outlet channels 3232 are straight channels, and the cross-sectional areas of the at least two outlet channels 3232 along the height direction of the main body 10 are equal. The areas of the second cross-sections of the at least two outlets 322 are equal. The outlet channels 3232 can also be configured with other shapes. The flow state of the liquid in the straight outlet channels 3232 is more similar, which is beneficial to ensuring that the water content of multiple cleaning components is consistent and to improving the cleaning quality of the cleaning equipment.

[0056] During the process of replenishing water to the cleaning component 20, the liquid in the water tank 31 enters the inlet channel 3231 through the inlet 321 and flows to the connecting port 3233. From there, it is distributed through the connecting port 3233 to at least two outlet channels 3232. The liquid then flows from the outlet channels 3232 to the outlets 322 and enters the guide structure 21. The outlet channels 3232, outlets 322, and guide structures 21 on the cleaning component 20 are all configured in a corresponding manner. The distances from the connecting port 3233 to each outlet 322 are equal, ensuring that the liquid reaches the outlets 322 simultaneously and wets the flexible cleaning element 23 of the cleaning component 20 simultaneously. The water replenishment time for the cleaning component 20 is the same, ensuring that the cleaning component 20 receives sufficient water within a preset time and reaches a suitable moisture content, thereby improving the cleaning efficiency of the cleaning equipment.

[0057] Furthermore, during the design and manufacturing of the water supply component 32, ensuring that the lengths (L) of at least two outlets 322 are equal facilitates standardized design and production, improving production efficiency and product quality stability. Simultaneously, during maintenance and repair of the water supply component 32, it also allows staff to quickly locate and troubleshoot problems, reducing maintenance costs and complexity. If the lengths (L) of at least two outlets 322 are unequal, liquid cannot reach the outlets 322 simultaneously, preventing simultaneous replenishment of water to the flexible cleaning component 23. Within the predetermined replenishment time, the replenishment time of the flexible cleaning component 23 will differ, resulting in some flexible cleaning components 23 receiving less water, thus affecting the cleaning effect of the cleaning assembly 20.

[0058] Specifically, when the cleaning assembly 20 includes two sets, both sets of cleaning assemblies 20 are disposed at the bottom of the main body 10. Along the direction perpendicular to the height of the housing, the two sets of cleaning assemblies 20 are located on opposite sides of the connecting port 3233. Liquid flows from the connecting port 3233 to the outlet 322, splitting into two streams of liquid flowing away from each other.

[0059] Furthermore, at least two water outlet channels 3232 have equal cross-sectional areas along the height direction of the main body 10. At least two water outlets 322 have equal areas of their second cross-sections. The equal distances between each water outlet 322 and the connecting port 3233, the equal cross-sectional areas of each water outlet channel 3232 along the height direction of the main body 10, and the equal cross-sectional areas of each water outlet 322 along its own width direction ensure that liquid reaches the water outlet 322 simultaneously and that the flow rate of liquid onto the flexible cleaning element 23 is the same, guaranteeing consistent cleaning ability for each flexible cleaning element 23 and improving the uniformity of the cleaning effect of the cleaning equipment. The liquid can be evenly distributed through the connecting port 3233, ensuring that each flexible cleaning element 23 receives the same amount of water. This balances the pressure and flow rate of the liquid in each water outlet channel 3232, resulting in relatively stable pressure changes when the liquid flows out of the water outlet 322. Stable water pressure allows the liquid to be sprayed more evenly onto the flexible cleaning element 23, improving the wetting efficiency and quality of the flexible cleaning element 23. During the liquid diversion process, this embodiment effectively prevents uneven flow patterns, ensuring a more balanced liquid volume received by each cleaning component 20. This improves the consistency of the overall cleaning effect and avoids issues such as over-wetting of the mop in some areas and under-wetting in others. This design also reduces fluid turbulence and eddies, minimizing energy loss and allowing the liquid to flow more smoothly from the water tank 31 to the mop. This improves the water supply efficiency of the water supply components and reduces noise during operation, enhancing the user experience. Furthermore, the equal cross-sectional areas of all water outlet channels 3232 and water outlets 322 make it easier to determine and adjust the parameters of the water supply components. Engineers can optimize the cross-sectional areas of the water outlet channels 3232 and water outlets 322 according to the overall performance requirements of the cleaning equipment, greatly simplifying the design process, improving efficiency, facilitating subsequent performance upgrades and optimizations, and simplifying the manufacturing of the water outlet channels 3232 and water outlets 322.

[0060] Wherein, the area S1 of the first cross-section is not less than 5 mm². 2 and no more than 11mm 2 The area of ​​the first cross-section can be set to 5mm². 2 6mm 2 7mm 2 8mm 2 9mm 2 10mm 2 11mm 2One of them. The inlet 321 has a suitable flow area, thereby ensuring that the liquid flow rate from the water tank 31 to the water supply component 32 is neither too large nor too small, and that the cleaning component 20 has a suitable water content, ensuring better cleaning effect of the cleaning equipment. This setting also helps to maintain the pressure balance in the water supply component 32. During the process of liquid entering the water supply component 32 from the water tank 31 through the inlet 321, the inlet 321 can ensure that the liquid pressure is appropriate. Stable pressure helps to ensure that the liquid can flow evenly and continuously onto the flexible cleaning component 23, improving the stability and reliability of the wetting of the flexible cleaning component 23. The liquid will not cause additional pressure burden on the water tank 31 and the water supply component 32, affecting the service life of the cleaning equipment. If the area of ​​the first cross section is less than 5mm² 2 If the first cross-sectional area of ​​the water inlet 321 is too small, the liquid will enter the water supply component 32 too slowly, failing to meet the liquid requirements of the cleaning component 20. This results in the flexible cleaning element 23 not being wetted in time, affecting cleaning efficiency. If the area of ​​the first cross-section is greater than 11 mm², the liquid will be insufficient. 2 If the first cross-sectional area of ​​the inlet 321 is too large, too much liquid may rush into the water supply component 32 in a short time, which may exceed the bearing capacity of the outlet channel 3232 and the outlet 322, causing liquid to leak to the ground, etc. It may also cause the liquid in the water tank 31 to be consumed too quickly, requiring frequent water filling.

[0061] The outlet 322 has a second cross-section S2 along its width direction, and at least two outlets 322 have equal second cross-sections, with the area of ​​the second cross-section not less than 0.8 mm². 2 and no more than 3.5mm 2 The area of ​​the second cross-section of the outlet 322 can be set to 0.8 mm². 2 1.0mm 2 1.2mm 2 1.4mm 2 1.6mm 2 1.8mm 2 2.0mm 2 2.2mm 2 2.4mm 2 2.6mm 2 2.8mm 2 3.0mm 2 3.2mm 2 3.4mm 2 3.5mm 2One of them. The second cross-sections of multiple water outlets 322 are equal, ensuring a uniform flow of water from each outlet 322. This allows the flexible cleaning components 23 on each cleaning assembly 20 to be wetted to the same degree, effectively preventing some flexible cleaning components 23 from being too wet and others too dry, ensuring uniform cleaning effect and improving cleaning quality. The area of ​​the second cross-section is not less than 0.8 mm². 2 and no more than 3.5mm 2 The water outlet 322 provides an appropriate amount of water to the flexible cleaning component 23, allowing it to be fully soaked to effectively remove stains from the floor and improve cleaning efficiency. If the area of ​​the second cross-section is less than 0.8 mm²... 2 If the second cross-sectional area of ​​the water outlet 322 is too small, the amount of water flowing out of the water outlet 322 per unit time will be too small, and the flexible cleaning component 23 will not be fully wetted, making it difficult to effectively remove stains from the ground. If the second cross-sectional area of ​​the water outlet 322 is too large, it may result in excessive water flow, excessive moisture content in the flexible cleaning component 23, excessive ground humidity, obvious water stains, affecting cleaning efficiency, and may also cause safety hazards such as slippery ground.

[0062] like Figures 11 to 12 As shown, in one embodiment, the water tank 31 is provided with a liquid storage chamber 01, an overflow chamber 03, and a second overflow port 02. The second overflow port 02 is located on the side wall of the overflow chamber 03 to connect the liquid storage chamber 01 and the overflow chamber 03. The bottom of the main body 10 is also provided with a first overflow port 40, which is connected to the overflow chamber 03. Along the height direction of the main body 10, there is a first height between the second overflow port 02 and the bottom of the liquid storage chamber 01. When the water level in the water tank 31 is higher than the first height, the first overflow port 40 is used to discharge water that exceeds the first height. The maximum value of the width of the first overflow port 40 is greater than the maximum value of the width of the outlet 322.

[0063] When the water level in the water tank 31 exceeds the first height, the first overflow port 40 can promptly discharge the water exceeding the first height, effectively preventing excessive pressure inside the water tank 31 caused by an excessively high water level, which could lead to liquid leakage outside the water tank 31 and damage to the internal circuitry of the cleaning equipment. The first overflow port 40 helps maintain a relatively stable water level in the water tank 31, thereby ensuring the stable operation of the water supply components. When the water level in the water tank 31 is too high, excess water is promptly discharged through the first overflow port 40, avoiding unstable water supply pressure due to excessively high water levels. This allows the outlet 322 to supply water to the flexible cleaning component 23 with a relatively stable pressure and flow rate, ensuring the consistency of the wetting and cleaning effects of the flexible cleaning component 23. The maximum width of the first overflow port 40 is greater than the maximum width of the outlet 322. This design allows the first overflow port 40 to quickly and effectively discharge excess water, ensuring that the drainage speed of the first overflow port 40 is greater than the speed at which liquid flows out from the outlet 322. When the water level in water tank 31 is too high, the first overflow port 40 has a large width, which can ensure that the water flows out quickly and rapidly reduce the water level in water tank 31.

[0064] The cleaning component 20 has a first projection area at the bottom of the main body 10, which is offset from the first overflow port 40. Because the first projection area of ​​the cleaning component 20 at the bottom of the main body 10 is offset from the first overflow port 40, after the cleaning equipment returns to the base station, regardless of whether the base station first fills the water tank of the cleaning equipment or cleans the cleaning component, excess water in the water tank can flow directly into the cleaning tank of the base station through the first overflow port 40. Water coming out of the first overflow port 40 will not drip onto the cleaning component 20, preventing excessive water content in the cleaning equipment when it leaves the base station. During the cleaning process, the cleaning equipment will not leave obvious watermarks on the surface to be cleaned, resulting in a better user experience.

[0065] The water tank 31 is equipped with a water inlet hole 311, the maximum width of which is less than the maximum width of the first overflow port 40. The maximum width of the first overflow port 40 is not less than 2mm and not more than 3mm. The maximum width of the first overflow port 40 can be set to one of the following: 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, or 3mm. When the water level in the water tank 31 exceeds the normal height, the first overflow port 40 provides sufficient passage for excess water to be discharged smoothly and promptly, preventing water from overflowing from the water tank 31. This protects the cleaning equipment from water damage and ensures its normal operation. When the water level is abnormal, and the water level in the water tank 31 is higher than the first height, the drainage rate of the first overflow port 40 is greater than the rate at which water is injected into the water tank 31 through the water inlet 311. The first overflow port 40 can promptly discharge water exceeding the first height, effectively preventing the water level in the water tank 31 from continuing to rise. This prevents excessive pressure inside the water tank 31 due to an excessively high water level, which could cause liquid leakage outside the water tank 31 and damage the internal circuitry of the cleaning equipment. In this embodiment, the maximum width of the water inlet 311 can also be set to be greater than the maximum width of the first overflow port 40. The size of the first overflow port 40 is made smaller than that of the water inlet 311. For example, if the maximum width of the water inlet 311 is 3 mm, the maximum width of the first overflow port 40 can be no less than 2 mm and no more than 3 mm (when the first overflow port 40 is a circular hole, that is, the diameter of the first overflow port 40 is no less than 2 mm and no more than 3 mm). The smaller first overflow port 40 can more accurately control the water level in the water tank 31, avoiding excessive water level fluctuations due to excessive overflow, which would reduce the actual water storage capacity of the water tank 31. This helps to stabilize the water level in the water tank 31 at a predetermined level (such as at the first height level in this embodiment), so that there is enough water to supply the cleaning component 20 during the cleaning process. Secondly, the smaller first overflow port 40 can also reduce the water flow noise generated during overflow, improving the comfort of the user environment. In addition, since the first overflow port 40 is located at the bottom of the main body 10, a smaller first overflow port 40 can save installation space at the bottom of the main body 10, improve the space utilization of the main body 10, and improve the aesthetics of the bottom of the main body 10 (a larger first overflow port 40 will reduce the aesthetics of the main body 10 and appear slightly abrupt).

[0066] Furthermore, at least one set of cleaning components 20 has an inward-facing state and an outward-facing state, and along the height direction of the main body 10, the outlet 322 is at least partially disposed opposite to the flow guiding structure 21. When the cleaning component 20 is in the outward-facing state, the portion outside the edge contour of the main body 10 is larger than the portion outside the edge contour of the main body 10 when the cleaning component 20 is in the inward-facing state.

[0067] The cleaning component 20 can rotate relative to the main body 10 in a first clockwise direction or a second clockwise direction. The first clockwise direction and the second clockwise direction are opposite. In this embodiment, the first clockwise direction is clockwise. Figure 2 The direction indicated by the middle arrow P. The second clockwise direction is counterclockwise, as shown below. Figure 2 The direction indicated by the middle arrow Q. The cleaning equipment is configured such that when the cleaning component 20 rotates in a first clockwise direction and is subjected to a frictional torque in a second clockwise direction, the cleaning component 20 swings to an outward expansion state in the second clockwise direction; when the cleaning component 20 rotates in the second clockwise direction and is subjected to a frictional torque in the first clockwise direction, the cleaning component 20 swings to an inward retraction state in the first clockwise direction. The cleaning component 20 can swing between the inward retraction state and the outward expansion state while rotating under the action of frictional torque. The cleaning component 20 can automatically swing relative to the main body 10 without the need for additional power actuators, reducing the complexity and cost of the cleaning equipment.

[0068] In the retracted state, the flow guiding structure 21 has a first projected outer contour on the body 10 along the height direction. In the expanded state, the flow guiding structure 21 has a second projected outer contour on the body 10 along the height direction. The outlet 322 is at least partially located within the overlapping area of ​​the first and second projected outer contours. When the cleaning component 20 is located in any of the retracted, expanded, or positions between the retracted and expanded states, the liquid flowing from the outlet 322 along the height direction of the body 10 can enter the flow guiding structure 21 to wet the cleaning component 20, ensuring a good water replenishment effect for the cleaning component 20.

[0069] In one embodiment, such as Figure 10As shown, at least one set of cleaning components 20 has an inward retracted state and an outward expanding state, and the water supply component also includes a liquid outlet 33. The liquid outlet 33 is disposed between the main body 10 and the flow guiding structure 21, and the liquid outlet 33 can move relative to the main body 10 as the cleaning components 20 move. At least one water outlet 322 is provided on the liquid outlet 33. The water outlet 322 is located on the liquid outlet 33. Since the liquid outlet 33 can move with the cleaning component 20, and the projected outer contour of the water outlet 322 is located within the projected outer contour of the guide structure 21, the water outlet 322 and the guide structure 21 move synchronously during the swinging process of the cleaning component 20 between the inward and outward states. Along the first direction, the position of the water outlet 322 relative to the guide structure 21 remains unchanged, that is, the water outlet 322 is always corresponding to the guide structure 21. The liquid flowing out of the water outlet 322 can flow directly onto the guide structure 21, and will not be splashed out by the cleaning component 20 due to dripping to other positions of the cleaning component 20. This effectively prevents the liquid from splashing outside the guide structure 21 onto the ground or other cleaning surfaces, or walls or other edge obstacles. Therefore, the liquid supplied to the cleaning component 20 will not fall onto the ground during the swinging process of the cleaning component 20, ensuring that the cleaning equipment can achieve better cleaning results and improving the user experience.

[0070] When the cleaning component 20 cleans along corner areas such as wall corners, the cleaning component 20 is in an outward expansion state, with at least a portion of the cleaning component 20 extending beyond the edge contour of the main body 10. The cleaning component 20 can perform edge cleaning of corner areas such as wall corners, reducing blind spots and dead corners, improving the cleaning rate, achieving ideal cleaning results, and providing a good user experience.

[0071] When the cleaning component 20 is in the retracted state, the cleaning component 20 may be completely within the edge contour of the main body 10 or may partially extend beyond the edge contour of the main body 10.

[0072] like Figures 8 to 9As shown, in one embodiment, the main body 10 includes a top shell 11 and a bottom shell 12. The bottom shell 12 is disposed at the bottom of the top shell 11 and forms an installation space with the top shell 11. The water tank 31 is disposed within the installation space. The water supply component 32 includes a cover plate 34, which covers the bottom shell 12 on the side near the top shell 11 and forms a water supply channel 323 with the bottom shell 12. The water inlet 321 is disposed on the cover plate 34. The water tank 31 is disposed within the installation space, making full use of the internal space of the main body 10, making the placement of the water tank 31 more regular, and also facilitating the fixing and protection of the water tank 31. The cover plate 34 of the water supply component 32 and the bottom shell 12 form a water supply channel 323. This arrangement makes full use of the space of the bottom shell 12, realizes the arrangement of the water supply channel 323, and improves the compactness of the cleaning equipment. The water supply component 32 adopts a method of cooperation between the cover plate 34 and the bottom shell 12, which makes the assembly and disassembly of the water supply component 32 more convenient and improves the convenience of maintenance.

[0073] like Figures 4 to 7 As shown, the water supply component also includes a water pump 35. A water inlet 312 is provided on the water tank 31. The water pump 35 includes a first interface 351 and a second interface 352. The first interface 351 is connected to the water inlet 312. A water supply component 32 is connected between the second interface 352 and the outlet 322. The water pump 35 is used to discharge water from the water tank 31 to the cleaning component 20 through the outlet 322. The water inlet 312 is connected to the first structure 351 via an inlet pipe 3121. Water enters the water tank 31 through the water inlet pipe 3111 and then into the water tank 31 via the water inlet hole 311. The water pump 35 can precisely control the water supply according to cleaning needs. By adjusting the power or running time of the water pump 35, water from the water tank 31 can be precisely discharged to the cleaning component 20 through the outlet 322, ensuring that the cleaning component 20 receives an appropriate amount of water, preventing water accumulation in the cleaning area due to excessive water or poor cleaning effect due to insufficient water. Compared to methods relying on natural gravity for water supply, the water pump 35 can distribute water more stably and evenly to each outlet 322, ensuring that different parts of the cleaning components 20 receive the same amount of water, thus improving the uniformity and consistency of cleaning. The water pump 35 can provide a certain water pressure, causing water to be sprayed out of the outlet 322 at a certain pressure, better wetting the cleaning components 20, such as mops, allowing the cleaning components 20 to more effectively absorb and remove stains, thereby improving the cleaning ability of the cleaning equipment.

[0074] like Figure 13As shown, in another embodiment, the main body 10 is provided with a water outlet 322. The water supply component 30 also includes a connecting member 36 and a connecting pipe 37. The connecting member 36 is disposed at the bottom of the main body 10 and communicates with the water outlet 322. One end of the connecting pipe 37 communicates with the water inlet 321, and the other end of the connecting pipe 37 communicates with the connecting member 36. The end of the connecting pipe 37 near the connecting member 36 can be sleeved on the outside of the connecting member 36, or the connecting pipe 37 can be inserted inside the connecting member 36, or the connecting pipe 37 can at least partially pass through the connecting member 36 to the outside of the water outlet 322. The connecting pipe 37 can be a flexible hose, which has good flexibility and is not easy to break or tear.

[0075] In another embodiment, at least one water outlet 322 is correspondingly arranged to at least two sets of cleaning components 20. At least one water outlet 322 can simultaneously supply water to at least two sets of cleaning components 20, reducing the number of water outlets 322 and thus lowering the processing complexity of the main body 10. In another embodiment, at least two water outlets 322 are corresponding one-to-one to at least two sets of cleaning components 20. In yet another embodiment, at least one set of cleaning components 20 is correspondingly arranged to at least two water outlets 322. The above embodiments can be implemented individually or simultaneously.

[0076] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0077] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0078] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
