[0003] Existing sewage tanks typically only have pumping and discharging functions. After pumping and discharging, a large amount of dirt inevitably remains on the inner walls of the tank. If the tank is not cleaned in time, bacteria can easily grow. However, cleaning the inner walls of existing sewage tanks mainly relies on manual operation by the user, which is cumbersome and results in a poor user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a sludge collection mechanism and cleaning equipment to solve the problem that the cleaning of the inner wall of the sewage tank in the prior art mainly relies on manual operation by the user, which is cumbersome and results in a poor user experience.

[0005] According to one aspect of the present invention, a sludge collection mechanism is provided, comprising: The main body has a receiving cavity; A liquid inlet channel is tangential to and communicates with the peripheral sidewall of the accommodating cavity, so that the liquid transported by the liquid inlet channel flows along the peripheral sidewall of the accommodating cavity, and the first communication position between the liquid inlet channel and the accommodating cavity is located near the top of the main body. A liquid outlet channel, which is connected to the bottom of the accommodating cavity; A sludge extraction channel, which is connected to the receiving cavity.

[0006] Furthermore, the peripheral wall of the accommodating cavity includes an arc-shaped surface, and the liquid inlet channel is tangential to the arc-shaped surface.

[0007] Furthermore, the sludge extraction channel is connected to the top of the accommodating cavity, and the sludge collection mechanism also includes a sludge collection tray, which is connected to the sludge extraction channel. The flow cross-sectional area of ​​the liquid inlet channel is larger than that of the liquid outlet channel.

[0008] Furthermore, the peripheral wall of the accommodating cavity is provided with an annular guide portion, which is arranged around the circumference of the accommodating cavity and close to the top of the accommodating cavity, and the side of the annular guide portion close to the top of the accommodating cavity is connected to the first communication position.

[0009] Furthermore, the top of the main body is provided with an exhaust port communicating with the accommodating cavity, and the sludge collection mechanism also includes a liquid level detection component, which is disposed in the accommodating cavity, and has a first position where the exhaust port is opened by moving away from the top of the accommodating cavity under the action of gravity, and a second position where the exhaust port is blocked by the buoyancy exerted by the liquid in the accommodating cavity.

[0010] Furthermore, the liquid level detection component includes: A float is disposed in the receiving cavity and can swing between the first position and the second position along the height direction of the receiving cavity; A detection component is disposed between the top of the accommodating cavity and the float. The detection component includes a magnet and a Hall switch, with one of the magnet and the Hall switch disposed at the top of the accommodating cavity and the other disposed at the float.

[0011] Furthermore, a sealing element is provided on the side of the liquid level detection component near the top of the accommodating cavity; wherein, when the liquid level detection component is in the second position, the sealing element seals the vent.

[0012] Furthermore, the main body is also provided with an exhaust channel communicating with the accommodating cavity, and the sludge collection mechanism also includes an air extraction component and a sludge collection tray. The exhaust channel has the exhaust port, the air extraction component is communicating with the exhaust channel, and the sludge collection tray is communicating with the air extraction channel.

[0013] Furthermore, the sludge extraction channel is tangent to and communicates with the peripheral sidewall of the accommodating cavity. The second communication position between the sludge extraction channel and the accommodating cavity is located near the top of the main body, and along the height direction of the accommodating cavity, the second communication position is at the same height as the first communication position.

[0014] Furthermore, the sludge collection mechanism also includes a flow guide, which is rotatably disposed on the top of the receiving cavity and extends to the peripheral wall of the receiving cavity. The side of the flow guide away from the bottom of the receiving cavity contacts the top surface of the main body. The flow guide is at least used to guide the liquid conveyed by the liquid inlet channel from the peripheral wall of the receiving cavity to the geometric center of the top of the receiving cavity.

[0015] Furthermore, the flow guide includes a connecting portion and a plurality of flow guide blades. The connecting portion is rotatably disposed at the center of the top of the accommodating cavity. The plurality of flow guide blades are spaced apart along the circumference of the connecting portion, and each flow guide blade extends from the connecting portion to the peripheral wall of the accommodating cavity.

[0016] Furthermore, the main body includes a first shell and a second shell, the second shell being detachably disposed on the first shell and forming the accommodating cavity together with the first shell, and the first shell being provided with the liquid inlet channel and the liquid outlet channel.

[0017] On the other hand, the present invention also provides a cleaning device, which includes the aforementioned dirt collection mechanism.

[0018] In this invention, the inlet channel is tangentially connected to and communicates with the peripheral wall of the receiving cavity. This arrangement allows the liquid transported through the inlet channel to acquire initial kinetic energy along the tangential direction of the sidewall upon entering the receiving cavity. This directional kinetic energy enables the liquid to naturally form a stable circulation along the peripheral wall, thereby cleaning the sidewall surface of the receiving cavity. Simultaneously, because the first communication point between the inlet channel and the receiving cavity is located near the top of the main body, the rotating liquid, under its own gravity and the impetus of continuous liquid injection, will gradually flow from the top to the bottom in a spiral descent. The entire flow process can fully cover the peripheral wall surface of the receiving cavity, leaving no cleaning dead zones. During this rotating flow process, the liquid, through its own impact force and friction with the sidewall, can effectively flush away stains adhering to the sidewall, thereby peeling these stains off the sidewall and carrying them into the flowing liquid. Ultimately, these impurities accumulated at the bottom will be discharged from the container cavity along with the liquid through the liquid outlet channel at the bottom. This achieves automatic cleaning and impurity discharge of the container cavity's perimeter walls without the need for additional cleaning components, relying solely on the liquid's own flow. The entire cleaning process does not require manual operation by the user, improving the user experience. Attached Figure Description

[0021] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] As mentioned in the background section, existing sewage tanks typically only have pumping and discharging functions. After pumping and discharging, a large amount of dirt inevitably remains on the inner wall of the sewage tank. If the tank is not cleaned in time, bacteria can easily grow. However, cleaning the inner wall of existing sewage tanks mainly relies on manual operation by the user, which is cumbersome and results in a poor user experience. To address this, the inventors of this utility model have designed a new dirt collection mechanism. This mechanism can at least solve the problem that cleaning the inner wall of sewage tanks in the prior art mainly relies on manual operation, which is cumbersome and results in a poor user experience. The dirt collection mechanism of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1 to 3 As shown, according to an embodiment of the present invention, a sludge collection mechanism is provided, which includes a main body 10, an inlet channel 20, an outlet channel 30, and a sludge extraction channel 70.

[0026] The main body 10 has a receiving cavity 101; the liquid inlet channel 20 is tangent to and communicates with the peripheral wall of the receiving cavity 101, so that the liquid transported by the liquid inlet channel 20 flows along the peripheral wall of the receiving cavity 101, and the first communication position 201 between the liquid inlet channel 20 and the receiving cavity 101 is located near the top of the main body 10; the liquid outlet channel 30 communicates with the bottom of the receiving cavity 101; and the sludge suction channel 70 communicates with the receiving cavity 101.

[0027] When the dirt collection mechanism of this utility model is installed on a cleaning device 100, such as a sweeping robot, a mopping robot, a sweeping and mopping robot, or a cleaning base station, the water supply component of the cleaning device 100 is connected to the liquid inlet channel 20. The water supply component provides liquid to the liquid inlet channel 20 and allows the liquid to enter the receiving cavity 101. At the same time, the dirt extraction channel 70 is connected to the dirt collection component on the cleaning device 100 to transport the collected dirt to the receiving cavity 101. Meanwhile, since the liquid inlet channel 20 in this embodiment is tangent to and connected to the peripheral wall of the receiving cavity 101, after the liquid enters the receiving cavity 101 through the liquid inlet channel 20, the liquid will form a rotating flow along the peripheral wall. And since the first connection position 201 between the liquid inlet channel 20 and the receiving cavity 101 is close to the top of the main body 10, the rotating liquid can flow from the top to the bottom of the receiving cavity 101, thereby covering a larger area of ​​the inner wall surface. During this process, the rotating liquid washes over the peripheral walls of the cavity 101, removing stains and impurities adhering to the inner walls and reducing residue. Simultaneously, under centrifugal force, impurities carried by the liquid gradually accumulate at the bottom of the cavity 101 and are eventually discharged through the outlet channel 30 connected to the bottom. Thus, the entire cleaning process relies solely on the flow of liquid to achieve self-cleaning of the peripheral walls of the cavity 101, eliminating the need for manual cleaning by the user. This saves on tedious manual operations, maintains the cleanliness of the inner walls, and enhances the user experience.

[0028] In other words, in this embodiment, by making the liquid inlet channel 20 tangential and connected to the peripheral sidewall of the accommodating cavity 101, the liquid transported through the liquid inlet channel 20 gains initial kinetic energy along the tangential direction of the sidewall upon entering the accommodating cavity 101. This directional kinetic energy allows the liquid to naturally form a stable circulation along the peripheral sidewall, thereby cleaning the sidewall surface of the accommodating cavity 101. Simultaneously, since the first connection point 201 between the liquid inlet channel 20 and the accommodating cavity 101 is located near the top of the main body 10, the rotating liquid, under its own gravity and the impetus of continuous liquid injection, will gradually flow from the top to the bottom in a spiral descent. The entire flow process can fully cover the peripheral sidewall surface of the accommodating cavity 101, leaving no cleaning dead zones. During this rotating flow process, the liquid, through its own impact force and friction with the sidewall, can effectively flush away the stains adhering to the sidewall, thereby peeling these stains off the sidewall and carrying them into the flowing liquid. Ultimately, these impurities accumulated at the bottom will be discharged from the container cavity 101 along with the liquid through the liquid outlet channel 30 at the bottom. This achieves automatic cleaning and impurity discharge of the side walls of the container cavity 101 without the need for additional cleaning components, relying solely on the flow of the liquid itself. The entire cleaning process does not require manual operation by the user, thus improving the user experience.

[0029] like Figure 3As shown in the figure, the arrows indicate part of the flow path of the liquid after it enters the accommodating cavity 101 from the inlet channel 20.

[0030] For example, the water supply component in this utility model includes a clean water tank or a water tap; the liquid provided by the water supply component can be clean water, cleaning fluid, or a mixture of clean water and cleaning fluid.

[0031] It should be noted that in this invention, "the liquid inlet channel 20 is tangent to the peripheral wall of the accommodating cavity 101" means that when the end opening of the liquid inlet channel 20 contacts the peripheral wall of the accommodating cavity 101, there is only one point of tangency between them, and the direction of liquid flow inside the liquid inlet channel 20 is completely consistent with the tangent direction of the peripheral wall of the accommodating cavity 101 at that point of tangency. This tangential design is a prerequisite for allowing the liquid to flow along the side wall of the accommodating cavity 101. If the liquid inlet channel 20 is perpendicularly connected to the side wall of the accommodating cavity 101, the liquid will directly impact the side wall when it enters, and most of the kinetic energy will be canceled out, making it difficult to form a stable rotating flow. If there is a crossing angle, the liquid may deviate towards the center of the accommodating cavity 101, and the rotational force will be greatly reduced. The tangential setting allows the liquid to enter the accommodating cavity 101 with minimal energy loss, and naturally conforms to the side wall with its own flow velocity, thereby driving the surrounding liquid to form a circulation, providing the basic power for subsequent spiral descent, comprehensive flushing, and other effects.

[0032] Further, see Figure 3 As shown, the peripheral wall of the accommodating cavity 101 in this embodiment includes an arc-shaped surface, and the liquid inlet channel 20 is tangential to the arc-shaped surface.

[0033] Specifically, since the peripheral wall of the accommodating cavity 101 in this embodiment includes an arc-shaped surface, this design allows the smooth transition characteristics of the arc-shaped surface to work synergistically with the tangential design of the liquid inlet channel 20. After the liquid flows out of the liquid inlet channel 20, it can flow along the tangential direction of the arc-shaped surface, avoiding obstruction at right angles or angular structures, making the rotation trajectory more consistent, and reducing energy loss caused by turbulent flow. This stable rotating flow can continuously apply a uniform impact force to the arc-shaped surface, and combined with the friction between the liquid and the wall, it can efficiently remove stains adhering to the arc-shaped surface, and there will be no cleaning dead corners due to abrupt changes in the wall shape during the flow. At the same time, the smooth arc-shaped surface can reduce the frictional resistance of the liquid flow, reduce the impact wear on the peripheral wall, and extend the service life of the accommodating cavity 101; while the stable flow design can reduce the energy consumption of the water supply component while ensuring the cleaning effect, making the self-cleaning process more efficient.

[0034] Furthermore, in this embodiment, the sludge extraction channel 70 is connected to the top of the receiving cavity 101, and the sludge collection mechanism also includes a sludge collection tray 80, which is connected to the sludge extraction channel 70. The flow cross-sectional area of ​​the liquid inlet channel 20 is larger than that of the liquid outlet channel 30. It should be noted that in this embodiment, the "flow cross-sectional area of ​​the liquid inlet channel 20" refers to the area of ​​the cross-section obtained by cutting the liquid inlet channel 20 along the flow direction of the fluid; similarly, the "flow cross-sectional area of ​​the liquid outlet channel 30" refers to the area of ​​the cross-section obtained by cutting the liquid outlet channel 30 along the flow direction of the fluid. It is worth mentioning that in this embodiment, the sludge collection tray 80 is located near the cleaning component of the cleaning device 100 and is used to collect the debris cleaned by the cleaning component, such as solid debris, liquid debris, or solid-liquid debris.

[0035] Specifically, in this embodiment, the flow cross-sectional area of ​​the inlet channel 20 is larger than that of the outlet channel 30. This design allows the liquid to maintain a high input efficiency when entering the receiving cavity 101, while controlling the liquid discharge speed to form a dynamic balance of fast inflow and slow outflow. When the water supply unit delivers liquid to the inlet channel 20, the larger flow cross-sectional area ensures that the liquid enters the receiving cavity 101 with sufficient flow and pressure, providing stable power support for the formation and maintenance of the rotating flow state. This allows the liquid to quickly fill the receiving cavity 101 and form a rotating water flow with sufficient impact force, thereby covering the peripheral wall surface in a short time and enhancing the flushing effect on stains. The smaller flow cross-sectional area of ​​the outlet channel 30 slows down the liquid discharge speed, allowing the liquid to have a longer residence time in the receiving cavity 101. The rotating liquid can repeatedly flush the wall surface, and even some stains with strong adhesion can be peeled off through continuous impact and friction.

[0036] Meanwhile, because the flow cross-sectional area of ​​the inlet channel 20 is larger than that of the outlet channel 30, the injection rate of liquid in the accommodating cavity 101 is greater than the discharge rate. As a result, the liquid gradually accumulates in the accommodating cavity 101 and overflows to the top. Since the sludge suction channel 70 is connected to the top of the accommodating cavity 101 and also to the sludge collection tray 80, when the liquid overflows to the top of the accommodating cavity 101, it flows out of the sludge suction channel 70 along a path opposite to the conventional sludge suction direction, ultimately flowing to the connected sludge collection tray 80. During this process, the reverse-flowing liquid not only flushes away residual debris at the connection between the sludge collection tray 80 and the sludge suction channel 70, effectively preventing blockage and ensuring the normal operation of subsequent sludge suction, but also simultaneously cleans the inside of the sludge collection tray 80, reducing residual debris accumulation within it, thereby improving the overall cleaning effect and operational stability of the sludge collection mechanism.

[0037] Further, see Figure 3As shown, in this embodiment, the circumferential wall of the accommodating cavity 101 is provided with an annular guide portion 40. The annular guide portion 40 is arranged around the circumference of the accommodating cavity 101 and close to the top of the accommodating cavity 101. The side of the annular guide portion 40 close to the top of the accommodating cavity 101 is connected to the first communication position 201.

[0038] Specifically, the annular guide section 40 precisely guides the rotating liquid entering the receiving cavity 101 from the first connecting position 201. When the liquid enters the receiving cavity 101 from the inlet channel 20 near the top and forms a rotating flow along the peripheral wall, the annular guide section 40, which surrounds the peripheral wall and connects to the first connecting position 201 on the side near the top of the receiving cavity 101, ensures that the rotating liquid contacts the annular guide section 40 first during its downward flow. The protruding annular guide section 40, through its blocking and guiding effect, prevents the liquid from shifting towards the center of the receiving cavity 101 due to kinetic energy dispersion in the initial stage of rotation, ensuring that the liquid always flows in close contact with the peripheral wall and maintaining the stability of the rotating flow. At the same time, the circumferential arrangement of the annular guide section 40 ensures that the rotating liquid receives uniform guidance throughout the entire circumferential range, guaranteeing that the sidewalls of the receiving cavity 101 in all directions are fully flushed by the liquid, and preventing the residue from remaining in local areas due to uneven liquid flow. This design requires no additional power; structural optimization alone can improve the guidance and flushing efficiency of liquid flow, further enhancing the comprehensiveness and reliability of the self-cleaning mechanism of the dirt collection system.

[0039] Further, see Figures 4 to 6 As shown, the top of the main body 10 in this embodiment is provided with an exhaust port 61 that communicates with the accommodating cavity 101. The sludge collection mechanism also includes a liquid level detection component 50. The liquid level detection component 50 is disposed in the accommodating cavity 101, and the liquid level detection component 50 has a first position where it moves away from the top of the accommodating cavity 101 under the action of gravity to open the exhaust port 61, and a second position where it is blocked by the buoyancy exerted by the liquid in the accommodating cavity 101.

[0040] Specifically, when the liquid level in the accommodating cavity 101 is low, the liquid level detection component 50 is in the first position under the influence of gravity, and the vent 61 remains open. At this time, the gas generated during the liquid entry into the accommodating cavity 101, as well as the air originally present in the accommodating cavity 101, can be smoothly discharged through the vent 61, avoiding the formation of air pressure that hinders liquid injection due to gas stagnation, ensuring that the liquid can smoothly enter the accommodating cavity 101 and quickly form a rotating flow. As liquid is continuously injected, the liquid level in the accommodating cavity 101 gradually rises. When the liquid level reaches a certain height, the buoyancy generated by the liquid on the liquid level detection component 50 is greater than its own weight, and the liquid level detection component 50 rises to the second position and blocks the vent 61. During this process, the blocking of the vent 61 can use the pressure of the injected liquid to push the liquid in the accommodating cavity 101 towards the liquid outlet channel 30, accelerating the discharge of impurities with the liquid, while preventing the liquid from overflowing from the vent 61 due to violent shaking during the rotating flow. The liquid level detection component 50 achieves automatic control of the exhaust port 61 by balancing gravity and buoyancy, without the need for additional electrical control devices, which is simple in structure and reduces the risk of failure.

[0041] like Figures 4 to 5 As shown, Figure 4 A schematic diagram is shown when the liquid level detection component 50 is in the first position; Figure 5 A schematic diagram is shown when the liquid level detection component 50 is in the second position.

[0042] Further, see Figures 4 to 5 As shown, the liquid level detection component 50 in this embodiment includes a float 51 and a detection component 52. The float 51 is disposed in the receiving cavity 101 and can swing between a first position and a second position along the height direction of the receiving cavity 101. The detection component 52 is disposed between the top of the receiving cavity 101 and the float 51. The detection component 52 includes a magnet 521 and a Hall switch 522. One of the magnet 521 and the Hall switch 522 is disposed at the top of the receiving cavity 101, and the other is disposed on the float 51. It should be noted that the "height direction of the receiving cavity 101" in this utility model refers to... Figure 4 The direction indicated by the middle arrow X.

[0043] It is understood that in this embodiment, the magnet 521 may be disposed on the top of the receiving cavity 101, and the Hall switch 522 may be disposed on the float 51; alternatively, the magnet 521 may be disposed on the float 51, and the Hall switch 522 may be disposed on the top of the receiving cavity 101. Figure 4 The diagram shows the case where magnet 521 is positioned on float 51 and Hall switch 522 is positioned on top of receiving cavity 101.

[0044] Specifically, the presence of float 51 reflects changes in the liquid level within the receiving cavity 101. When the liquid level is low, float 51 is in its first position under its own weight. As the liquid level rises, buoyancy propels float 51 upwards to its second position. This position switching method, relying on buoyancy and gravity, accurately follows changes in liquid level, and the swinging design reduces interference from liquid rotation and flow on the float 51's position, ensuring switching stability. The cooperation between magnet 521 and Hall switch 522 in the detection component 52 converts the mechanical position change of float 51 into an electrical signal feedback. When float 51 is in the first position, magnet 521 and Hall switch 522 are relatively far apart, and Hall switch 522 is in its initial state. When float 51 swings to the second position, the distance between them shortens, and Hall switch 522 senses the change in magnetic field and triggers a signal. This non-contact detection method avoids wear or jamming that may occur with mechanical contact, extending the service life of detection component 52. Simultaneously, the signal feedback is rapid and accurate, allowing the cleaning equipment 100 to promptly obtain the liquid level status. Furthermore, the combination of the float 51 and the detection component 52 has a simple structure, requiring no complex transmission mechanism. Its installation within the accommodating cavity 101 does not obstruct liquid flow or affect impurity settling. Moreover, the combination of the magnet 521 and the Hall switch 522 achieves the detection function without additional power supply, reducing energy consumption. Overall, this liquid level detection component 50 can reliably sense changes in liquid level to coordinate with the opening and closing of the vent 61, and can also provide feedback via electrical signals to control the liquid supply of the cleaning equipment 100, ensuring stable and reliable operation of the dirt collection mechanism.

[0045] Further, see Figures 4 to 6 As shown, in this embodiment, a sealing element 53 is provided on the side of the liquid level detection component 50 near the top of the accommodating cavity 101; wherein, when the liquid level detection component 50 is in the second position, the sealing element 53 seals the exhaust port 61.

[0046] Specifically, the sealing element 53 ensures a tighter seal between the liquid level detection component 50 and the vent 61 when the liquid level detection component 50 is in the second position. This prevents liquid from leaking from the vent 61 due to the rotational flow or internal pressure of the accommodating cavity 101 caused by gaps between the liquid level detection component 50 and the vent 61. When the liquid level rises and the liquid level detection component 50 swings to the second position, the sealing element 53 will fit tightly against the edge of the vent 61, filling any gaps with its own elasticity or fitting properties to form a reliable sealing structure.

[0047] For example, the "sealant 53" in this embodiment includes silicone sheet, rubber sheet, etc. Any other modifications under the concept of this utility model are within the protection scope of this utility model.

[0048] Further, see Figure 5 and Figure 9As shown, in this embodiment, the main body 10 is also provided with an exhaust channel 60 communicating with the accommodating cavity 101. The sludge collection mechanism also includes an air extraction component 13 and a sludge collection tray 80. The exhaust channel 60 has an exhaust port 61. The air extraction component 13 communicates with the exhaust channel 60, and the sludge collection tray 80 communicates with the sludge extraction channel 70. It is worth mentioning that in this embodiment, the sludge collection tray 80 is located near the cleaning component of the cleaning equipment and is used to collect the waste swept by the cleaning component, such as solid waste, liquid waste, or solid-liquid waste.

[0049] Specifically, when the suction component 13 draws air out of the accommodating cavity 101 through the exhaust port 61, a negative pressure environment is formed inside the accommodating cavity 101. This negative pressure generates suction through the sludge extraction channel 70, thereby drawing the sewage in the sludge collection tray 80 into the accommodating cavity 101 without relying on additional pushing power, making sewage collection more efficient. The sludge collection tray 80 can collect sewage and impurities in a unified manner, facilitating subsequent cleaning or treatment of impurities. In other words, the connection between the suction component 13 and the exhaust port 61 utilizes the original structure of the exhaust port 61 to achieve negative pressure guidance, eliminating the need for additional interfaces on the main body 10, thus simplifying the structural design of the main body 10. The connection between the sludge extraction channel 70 and the accommodating cavity 101 expands the function of the sludge collection mechanism, enabling it to both self-clean the accommodating cavity 101 and actively extract external sewage, improving the integration level of the sludge collection mechanism.

[0050] It is worth mentioning that, since the suction component 13 in this embodiment is connected to the exhaust port 61, when the liquid level detection component 50 is in the second position, the sealing component 53 seals the exhaust port 61, thereby preventing liquid from entering the suction component 13 from the exhaust port 61 and extending the service life of the suction component 13.

[0051] For example, the air extraction component 13 in this embodiment includes a vacuum pump, a fan, an exhaust fan, etc. Any other modifications under the concept of this utility model are within the protection scope of this utility model.

[0052] Further, see Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the sludge extraction channel 70 is tangent to and connected to the peripheral sidewall of the accommodating cavity 101. The second connection position 701 of the sludge extraction channel 70 and the accommodating cavity 101 is located near the top of the main body 10, and along the height direction of the accommodating cavity 101, the second connection position 701 and the first connection position 201 are at the same height.

[0053] Specifically, since the sludge suction channel 70 is tangent to the periphery of the receiving cavity 101 and the second connecting position 701 and the first connecting position 201 are at the same height, when the liquid transported by the liquid inlet channel 20 forms a rotating flow field, it will naturally flow through the inlet of the sludge suction channel 70, and some of the liquid can enter the sludge suction channel 70 by the force of the rotation. This liquid flows in the sludge suction channel 70 with the kinetic energy generated by the rotation, which can flush away residual impurities attached to the inner wall of the channel and prevent impurities from accumulating and clogging the channel. The liquid entering the sludge collection tray 80 will use its own flow to flush the inside of the sludge collection tray 80, removing the stains and residual impurities attached to the sludge collection tray 80, and preventing stains from remaining for a long time, which may lead to bacterial growth or odor. At the same time, this method of cleaning using the liquid inlet channel 20 does not require additional cleaning devices or the addition of cleaning liquid. It can directly rely on the existing liquid flow to complete the cleaning of the sludge suction channel 70 and the sludge collection tray 80, simplifying the overall structure of the sludge collection mechanism.

[0054] Further, see Figure 7 As shown, the sludge collection mechanism in this embodiment also includes a guide member 90. The guide member 90 is rotatably disposed on the top of the receiving cavity 101 and extends to the peripheral wall of the receiving cavity 101. The side of the guide member 90 away from the bottom of the receiving cavity 101 contacts the top surface of the main body 10. The guide member 90 is at least used to guide the liquid conveyed by the liquid inlet channel 20 from the peripheral wall of the receiving cavity 101 to the geometric center of the top of the receiving cavity 101.

[0055] Specifically, since the guide member 90 is rotatably disposed at the top of the receiving cavity 101 and extends to the peripheral wall of the receiving cavity 101, when the liquid conveyed by the liquid inlet channel 20 flows along the peripheral wall of the receiving cavity 101, the liquid will contact the guide member 90 and drive the guide member 90 to rotate. The rotating guide member 90 can guide part of the liquid from the peripheral wall to the top geometric center area. This part of the guided liquid can flush the top center area of ​​the receiving cavity 101, making up for the insufficiency of the top center being difficult to cover by the circumferentially rotating liquid alone, and avoiding the residue of stains in this area due to the weak liquid flow. At the same time, during the rotation of the guide member 90 driven by the liquid, it will also disturb the surrounding liquid, enhance the flow activity of the liquid at the top of the receiving cavity 101, and make the liquid spread downward more evenly, further expanding the cleaning range. In addition, the rotation of the guide member 90 does not require additional power to drive it, but only relies on the kinetic energy of the liquid flow, and will not increase the energy consumption of the dirt collection mechanism. Furthermore, in this embodiment, by positioning the side of the guide member 90 away from the bottom of the receiving cavity 101 in contact with the top surface of the main body 10, dirt on the top surface of the main body 10 can be scraped off during the rotation of the guide member 90.

[0056] Further, see Figures 7 to 8As shown, the flow guide 90 in this embodiment includes a connecting part 91 and a plurality of flow guide blades 92. The connecting part 91 is rotatably disposed at the center of the top of the accommodating cavity 101. The plurality of flow guide blades 92 are disposed at intervals along the circumference of the connecting part 91, and each flow guide blade 92 extends from the connecting part 91 to the peripheral side wall of the accommodating cavity 101.

[0057] Specifically, the connecting part 91 is located at the top center of the accommodating cavity 101 and is rotatable, providing a stable rotation fulcrum for the entire guide member 90, ensuring that the guide vanes 92 can rotate uniformly around the center axis. Multiple guide vanes 92 are distributed circumferentially at intervals and extend from the center to the peripheral sidewall, thus ensuring full contact with the liquid flowing along the peripheral sidewall. When the liquid flows along the sidewall, it acts synchronously on each guide vane 92, propelling the guide member 90 to rotate smoothly as a whole, avoiding rotational jamming due to uneven force. The length of each guide vane 92 extending from the center to the sidewall allows the guide vane 92 to continuously guide the liquid from the peripheral sidewall towards the central area during rotation. Combined with the spaced arrangement, the channels formed between the guide vanes 92 can also guide the liquid to diffuse in different directions, allowing the liquid guided to the center to more evenly cover the top central area, enhancing the flushing effect on that area. Furthermore, the flow guide 90, which consists of a connecting part 91 and multiple guide vanes 92, has a simple structure and reliable strength. It generates little resistance when rotating and can be driven by only the conventional kinetic energy of the liquid flow without consuming additional energy. Moreover, the solid connection between the vanes and the connecting part 91 can withstand the impact of the liquid for a long time, ensuring the service life of the flow guide 90.

[0058] Further, see Figures 6 to 7 As shown, the main body 10 in this embodiment includes a first shell 11 and a second shell 12. The second shell 12 is detachably disposed on the first shell 11 and surrounds the first shell 11 to form a receiving cavity 101. The first shell 11 is provided with a liquid inlet channel 20 and a liquid outlet channel 30.

[0059] Specifically, the detachable connection between the second housing 12 and the first housing 11 allows the internal space of the accommodating cavity 101 to be directly exposed by disassembling the second housing 12 when deep cleaning or component maintenance is required. This facilitates the user's treatment of stubborn stains or residual dirt on the inner wall of the accommodating cavity 101, preventing the long-term accumulation of dirt in cleaning dead corners due to the enclosed structure. The design of the two housings enclosing the accommodating cavity 101 ensures the overall sealing of the accommodating cavity 101, preventing liquid leakage from the housing connection during rotation, flow, or transportation, and ensuring that the liquid can stably act on the sidewalls for flushing and impurity collection.

[0060] Meanwhile, the first housing 11 integrates an inlet channel 20 and an outlet channel 30, which reduces the number of interfaces connecting the pipeline to the housing, lowers the risk of liquid leakage, and makes the inlet and outlet paths more stable. The liquid transported by the inlet channel 20 can enter the receiving cavity 101 along a preset trajectory to form a rotating flow, while the outlet channel 30 can continuously discharge impurities accumulated at the bottom, avoiding the impact of loose interfaces on liquid flow efficiency. In addition, the detachable structure facilitates the replacement or maintenance of individual housings. If a housing is damaged, it is not necessary to replace the entire main body 10; only the corresponding housing needs to be replaced, reducing maintenance costs.

[0061] Optionally, the first housing 11 and the second housing 12 in this embodiment can be connected by screwing, snapping, or magnetic attraction. Any other modifications under the concept of this utility model are within the protection scope of this utility model.

[0062] On the other hand, this embodiment of the invention also provides a cleaning device 100, which includes the aforementioned dirt collection mechanism. Therefore, the cleaning device 100 includes all the technical effects of the aforementioned dirt collection mechanism. Since the technical effects of the dirt collection mechanism have already been described in detail above, they will not be repeated here.

[0063] Optionally, the cleaning equipment in this invention includes at least one of a cleaning robot and a cleaning base station. That is, the cleaning equipment is either a cleaning robot or a cleaning base station, or the cleaning equipment includes both a cleaning robot and a cleaning base station.

[0064] 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.

[0065] 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 utility model.

[0066] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
