Abstract
Description
Technical Field

[0002] Environmental sanitation is a crucial factor affecting the quality of life. Consequently, as people's expectations for quality of life continue to rise, so too do their demands for environmental sanitation. Consequently, a wide range of floor cleaning equipment has emerged, including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that cleans the floor while simultaneously sucking up wastewater and removing it from the site.
[0003] Existing floor scrubbers are generally provided with a solution bucket for storing cleaning solution and a sewage bucket for collecting sewage after cleaning.

[0049] The present disclosure provides a cleaning device, including a body and a sewage bucket, wherein the sewage bucket includes a barrel body, a self-cleaning component and a cover body; wherein the barrel body is constructed to enclose an inner cavity with an opening; the self-cleaning component is constructed to be detachably mounted on the upper part of the barrel body, and is constructed to output cleaning liquid to at least clean the inner wall of the barrel body; a gas pipeline and a gas-liquid separation component are provided on the cover body; the cover body is detachably mounted on the opening of the barrel body, and is located in the disassembly and assembly path of the self-cleaning component.
[0050] In this way, in the cleaning equipment disclosed in the present invention, the inner cavity inside the barrel body can be used to accommodate dirt, and during operation, the gas pipeline on the sewage barrel cover body can be connected to the fan unit, and the fan unit can form a negative pressure in the inner cavity of the barrel body, thereby sucking the dirt on the working surface into the inner cavity. Since the cover body is provided with a gas-liquid separation component, dirty liquid droplets can be prevented from entering the fan unit from the cover body.
[0051] When the cleaning device of the present disclosure is used in conjunction with a cleaning base station capable of automatic sewage discharge, the cleaning device of the present disclosure can be placed on the cleaning base station, and the dirt in the sewage bucket can then be automatically discharged into the cleaning base station. After the dirt is discharged, the self-cleaning component can be used to output cleaning liquid to at least clean the inner wall of the bucket, thereby cleaning the residual dirt on the inner wall of the sewage bucket. This eliminates the need for the user to manually clean the interior of the sewage bucket, which helps to reduce the user's usage burden and greatly improves the user experience.
[0052] Moreover, since the self-cleaning component is detachably mounted on the upper portion of the barrel body, the cover body is detachably mounted on the opening of the barrel body, and is located in the disassembly and assembly path of the self-cleaning component, when assembling the sewage barrel of the present invention, it is only necessary to place the self-cleaning component on the upper portion of the barrel body, and then mount the cover body on the opening of the barrel body.
[0053] When there is stubborn dirt that is difficult to remove in the barrel, the user can remove the sewage barrel from the body, and then remove the cover and self-cleaning component from the barrel in turn, and rinse the barrel, cover and self-cleaning component respectively to remove the stubborn dirt on the inner cavity of the sewage barrel, thereby achieving deep cleaning of all parts of the sewage barrel, preventing bacteria from growing in the sewage barrel, and effectively avoiding hygiene problems.
[0054] For ease of understanding, refer to Figures 1 to 11 , the specific structure and working principle of the cleaning device disclosed in the present invention are explained in detail with reference to an embodiment.
[0055] like Figures 1 to 3 、 Figure 10As shown, the present disclosure provides a cleaning device 10, comprising a body 1 and a sewage bucket 2, wherein the sewage bucket 2 comprises a barrel 21, a self-cleaning assembly 23, and a cover 22; wherein the barrel 21 is configured to enclose an inner cavity 211 having an opening; the self-cleaning assembly 23 is configured to be detachably mounted on the upper portion of the barrel 21 and is configured to output cleaning liquid to at least clean the inner wall of the barrel 21; the cover 22 is provided with a gas pipeline 221 and a gas-liquid separation assembly 222; the cover 22 is detachably mounted on the opening of the barrel 21 and is located in the disassembly and assembly path of the self-cleaning assembly 23. It is understood that the cleaning device 10 of the present disclosure can clean work surfaces such as floors and carpets, and the cleaning device 10 and the cleaning base station 20 can be docked with each other so that the cleaning device 10 discharges sewage into the cleaning base station 20. Moreover, the cleaning base station 20 can also charge the cleaning device 10, replenish cleaning liquid, etc., which will not be described in detail here. The cleaning device 10 may also include a cleaning liquid bucket, a floor brush assembly 3, and a fan unit 4. The cleaning liquid bucket is used to supply cleaning liquid to the cleaning element, or it may also provide cleaning liquid to the self-cleaning assembly 23. The floor brush assembly 3 is disposed at the bottom end of the body 1 and is used to clean work surfaces such as floors, carpets, or furniture surfaces. A rotating shaft may be provided between the floor brush assembly 3 and the body 1, allowing the floor brush assembly 3 to rotate relative to the body 1 via the rotating shaft, thereby facilitating the user to drag the cleaning device 10 back and forth to clean the work surface. When cleaning the work surface, the floor brush assembly 3 remains in contact with the work surface. The floor brush assembly 3 may include a floor brush housing and a cleaning element rotatably connected to the floor brush housing. The cleaning element may rotate relative to the work surface to wipe away stains on the work surface. The cleaning element may be a roller brush. As shown in the figure, a sewage suction pipe is provided within the portion where the body 1 connects to the floor brush assembly 3. The bottom end of the sewage suction pipe is connected to a sewage suction port provided on the floor brush assembly 3, and the sewage suction pipe is connected to the inner cavity 211 of the sewage bucket 2. The fan unit 4 is used to create a negative pressure in the sewage bucket 2, thereby sucking dirt on the working surface into the sewage bucket 2. The gas-liquid separation component 222 can isolate the gas outlet and the liquid inlet in the sewage bucket 2. When dirt on the working surface enters the sewage bucket 2, the liquid will fall to the bottom of the sewage bucket 2 under the action of gravity due to the obstruction of the gas-liquid separation component 222, while the gas will be sucked out of the sewage bucket 2 through the gas outlet on the cover 22, so that the liquid remains in the bucket body 21.
[0056] In this way, in the cleaning device 10 disclosed in the present invention, the inner cavity 211 in the barrel body 21 can be used to accommodate dirt, and during operation, the gas pipeline 221 on the cover body 22 of the sewage bucket 2 can be connected to the fan unit 4, and the fan unit 4 can form a negative pressure in the inner cavity 211 of the barrel body 21, thereby sucking the dirt on the working surface from the sewage suction pipe into the inner cavity 211. Since the gas-liquid separation component 222 is provided on the cover body 22, dirty liquid droplets can be prevented from entering the fan unit 4 from the cover body 22.
[0057] When the cleaning device 10 of the present disclosure is used in conjunction with a cleaning base station 20 capable of automatic sewage discharge, the cleaning device 10 of the present disclosure can be placed on the cleaning base station 20, and then the dirt in the sewage bucket 2 is automatically discharged into the cleaning base station 20. After the dirt is discharged, the cleaning base station 20 can provide cleaning liquid to the self-cleaning component 23 to clean at least the inner wall of the barrel body 21, thereby cleaning the residual dirt on the inner wall of the sewage bucket 2. The user does not need to manually clean the interior of the sewage bucket 2, which helps to reduce the user's usage burden and greatly improves the user experience.
[0058] Moreover, since the self-cleaning component 23 is detachably mounted on the upper portion of the barrel body 21, the cover body 22 is detachably mounted on the opening of the barrel body 21, and is located in the disassembly and assembly path of the self-cleaning component 23, when assembling the sewage barrel 2 of the present disclosure, it is only necessary to place the self-cleaning component 23 on the upper portion of the barrel body 21, and then install the cover body 22 on the opening of the barrel body 21.
[0059] When there is stubborn dirt that is difficult to remove in the barrel body 21, the user can remove the sewage barrel 2 from the body 1, and then remove the cover 22 and the self-cleaning component 23 from the barrel body 21 in turn, and rinse the barrel body 21, the cover 22 and the self-cleaning component 23 respectively to remove the stubborn dirt on the inner cavity 211 of the sewage barrel 2, thereby achieving deep cleaning of the various components of the sewage barrel 2, preventing bacteria from growing in the sewage barrel 2, and effectively avoiding hygiene problems.
[0060] In order to control the operation of the cleaning device 10 of the present disclosure, the cleaning base station 20 of the present disclosure may further include a control unit. The control unit can be connected to various components on the cleaning base station 20 of the present disclosure through signals to control their operating states.
[0061] like Figure 2 、 Figure 11 As shown, in one embodiment of the present disclosure, the top of the self-cleaning assembly 23 is constructed to be adjacent to the bottom of the cover body 22 and abut against the bottom of the cover body 22. When the top of the self-cleaning assembly 23 is adjacent to the bottom of the cover body 22 and abuts against the bottom of the cover body 22, the self-cleaning assembly 23 can be set at a higher position in the inner cavity 211 of the sewage bucket 2, so that the self-cleaning assembly 23 can output the cleaning liquid to a higher position on the inner wall of the barrel body 21, thereby increasing the cleaning area of the inner wall of the barrel body 21 by the cleaning liquid and minimizing the generation of cleaning dead corners. Moreover, when the top of the self-cleaning assembly 23 abuts the bottom of the cover body 22, in addition to enabling the self-cleaning assembly 23 to output the cleaning liquid to a higher position on the inner wall of the barrel body 21, it can also facilitate the barrel body 21 and the cover body 22 to jointly fix the self-cleaning assembly 23, preventing the self-cleaning assembly 23 from shaking up and down in the sewage bucket 2 during use of the cleaning device 10 of the present disclosure.
[0062] In another embodiment of the present disclosure, due to mechanical or manufacturing tolerances, the top of the self-cleaning assembly 23 cannot completely abut the bottom of the cover 22, but rather has a certain gap therebetween, which is understandable to those skilled in the art. That is, the top of the self-cleaning assembly 23 is adjacent to the bottom of the cover 22, and the gap between the top and the bottom of the cover 22 is less than a preset threshold. This also allows the self-cleaning assembly 23 to be positioned at a higher position in the inner cavity 211 of the sewage bucket 2, thereby enabling the self-cleaning assembly 23 to output cleaning liquid to a higher position on the inner wall of the bucket 21, thereby increasing the cleaning area of the inner wall of the bucket 21 by the cleaning liquid and minimizing the generation of cleaning blind spots.
[0063] Specifically, such as Figures 4 to 8 As shown, in one embodiment of the present disclosure, the self-cleaning component 23 includes a component body 231 provided with a guide channel 2311, and at least two first nozzles 232 provided on the component body 231 and connected to the guide channel 2311; the at least two first nozzles 232 are constructed to be distributed in sequence along the circumference of the component body 231, and are constructed to spray cleaning liquid at least onto the inner wall of the barrel body 21.
[0064] In this way, during the operation of the self-cleaning component 23 of the present invention, the guide channel 2311 in the component body 231 can provide cleaning liquid to each first nozzle 232, and at least two first nozzles 232 distributed in sequence along the circumference of the component body 231 can spray cleaning liquid to various circumferential locations of the inner wall of the barrel body 21, thereby cleaning various circumferential locations of the inner wall of the barrel body 21.
[0065] Specifically, such as Figure 4 and Figure 8 As shown, in one embodiment of the present disclosure, the first nozzle 232 has an ejection channel 2321, and the ejection channel 2321 forms a nozzle 2322 at its free end; the cleaning liquid is configured to flow out from the nozzle 2322 along the central axis of the ejection channel 2321; wherein the central axis of the ejection channel 2321 is configured to have an angle of 40° to 50° with the central axis of the barrel body 21.
[0066] During the operation of the self-cleaning component 23 disclosed in the present invention, the cleaning liquid flows out from the nozzle 2322 along the central axis of the ejection channel 2321 to the inner wall of the barrel body 21. Since the angle between the central axis of the ejection channel 2321 and the central axis of the barrel body 21 is 40° to 50°, that is, in the vertical plane, the angle between the flow direction of the cleaning liquid and the inner wall of the barrel body 21 is relatively appropriate, which can ensure that the cleaning liquid can cover most of the area in the height direction of the inner wall of the barrel body 21, and the cleaning liquid will not lose too much kinetic energy when flowing to the inner wall of the barrel body 21. The cleaning liquid still has more kinetic energy in the process of continuing to flow downward along the inner wall of the barrel body 21, thereby effectively improving the cleaning effect of the cleaning liquid on the inner wall of the barrel body 21, and facilitating the cleaning liquid to remove stubborn stains on the inner wall of the barrel body 21.
[0067] In a specific embodiment of the present disclosure, the central axis of the ejection channel 2321 is configured to have an angle of 45° with the central axis of the barrel body 21 , thereby effectively improving the cleaning effect of the cleaning liquid on the inner wall of the barrel body 21 .
[0068] Further, such as Figure 6 and Figure 7 As shown, in one embodiment of the present disclosure, the intersection of the central axis of the ejection channel 2321 and the inner wall of the inner cavity 211 is recorded as point A, and the angle between the projection of the central axis B of the ejection channel 2321 on the cross section of the barrel body 21 and the tangent C at point A on the barrel body 21 is 40° to 50°.
[0069] During the operation of the self-cleaning component 23 disclosed in the present invention, the cleaning liquid flows out from the nozzle 2322 along the central axis of the spray channel 2321 to the inner wall of the barrel body 21. The intersection of the central axis of the spray channel 2321 and the inner wall of the inner cavity 211 is recorded as point A. The positive projection of the central axis of the spray channel 2321 on the cross section of the barrel body 21 and the tangent of point A on the barrel body 21 have an angle of 40° to 50°, that is, in the horizontal plane. The angle between the flow direction of the cleaning liquid and the inner wall of the barrel body 21 is also relatively appropriate. The cleaning liquid will not lose too much kinetic energy when flowing to the inner wall of the barrel body 21, and can continue to rotate along the inner wall of the barrel body 21 during the process of flowing downward along the inner wall of the barrel body 21, thereby increasing the corresponding cleaning area of each first nozzle 232, reducing cleaning dead angles, and improving the cleaning effect. In one embodiment of the present disclosure, the intersection of the central axes of the various ejection channels 2321 on the inner wall of the inner cavity 211 is constructed to be located on the same cross-section of the barrel body 21. Since the intersection of the central axes of the various ejection channels 2321 on the inner wall of the inner cavity 211 is located on the same cross-section of the barrel body 21, the cleaning liquid ejected by each first nozzle 232 can be sprayed to the same height of the inner wall of the inner cavity 211, thereby forming a uniform cleaning liquid water curtain on the inner wall of the inner cavity 211. The kinetic energy of the cleaning liquid ejected by each first nozzle 232 can be evenly superimposed on the inner wall of the barrel body 21, maximizing the utilization of the kinetic energy of the cleaning liquid and improving the cleaning effect. This avoids inconsistent flow rates of the cleaning liquid in some areas of the inner wall of the barrel body 21 due to inconsistent heights of the cleaning liquid ejected by some first nozzles 232, which easily results in large kinetic energy loss when the cleaning liquid is superimposed, and the cleaning liquid in the lower part of the inner wall of the barrel body 21 becomes a relatively weak water flow, resulting in poor cleaning effect.
[0070] like Figure 7 As shown, in one embodiment of the present disclosure, the central axis of each ejection channel 2321 is configured to extend obliquely in the circumferential direction of the barrel body 21 along the same deflection direction. The same deflection direction here refers to the inclination direction of the central axis of each ejection channel 2321 corresponding to its arrangement direction. For example, when a plurality of ejection channels 2321 are arranged at annular intervals, the central axis of each ejection channel 2321 can be inclined in the clockwise or counterclockwise direction of the ring. Furthermore, the deflection angle of the central axis of each ejection channel 2321 extending obliquely in the same deflection direction is the same. It can be understood that, as Figure 7 As shown, the central axis of each ejection channel 2321 can be inclined and extended in the clockwise direction on the circumference of the barrel body 21; the central axis of each ejection channel 2321 can also be inclined and extended in the counterclockwise direction on the circumference of the barrel body 21, which is not limited here.
[0071] Since the central axis of each ejection channel 2321 extends obliquely in the circumferential direction of the barrel body 21 along the same deflection direction, the cleaning liquid ejected by each first nozzle 232 can form a spirally flowing cleaning liquid water curtain on the inner wall of the barrel body 21, so that the cleaning liquid ejected by each first nozzle 232 can cover all circumferential parts of the inner wall of the barrel body 21, avoiding the occurrence of cleaning dead corners on the circumferential direction of the inner wall of the barrel body 21.
[0072] like Figure 8 As shown, in one embodiment of the present disclosure, the end surface of the nozzle 2322 is configured to be perpendicular to the central axis of the ejection channel 2321 and to form an angle with the cross-section of the barrel body 21. This results in the end surface of the nozzle 2322 being an inclined surface, with the inclined surface facing the inner wall of the inner cavity 211. Since the end surface of the nozzle 2322 is perpendicular to the central axis of the ejection channel 2321, the cleaning liquid is uniformly ejected from the nozzle 2322 along the ejection channel 2321. The cleaning liquid is less susceptible to interference from the nozzle 2322, its flow direction remains unchanged, and the kinetic energy attenuation of the cleaning liquid flowing through the ejection point is relatively small. Furthermore, the angle between the end surface of the nozzle 2322 and the cross-section of the barrel body 21, with the inclined surface of the nozzle 2322 facing the wall of the barrel body 21, facilitates the formation of an angle when the cleaning liquid flows onto the inner wall of the barrel body 21, thereby reducing the kinetic energy loss of the cleaning liquid at the inner wall of the barrel body 21.
[0073] Further, such as Figure 8 As shown, in one embodiment of the present disclosure, the first nozzle 232 includes a nozzle body 2323 having a liquid channel. The nozzle body 2323 is configured to extend in the direction of the central axis of the barrel body 21, and the ejection flow channel 2321 is configured to communicate with the liquid channel of the nozzle body 2323. Thus, during the operation of the self-cleaning assembly 23 of the present disclosure, the guide channel 2311 in the component body 231 can provide cleaning liquid into the nozzle body 2323 of each first nozzle 232. The cleaning liquid can flow along the liquid channel of the nozzle body 2323 to the ejection flow channel 2321 and be ejected from the nozzle 2322. Since the nozzle body 2323 of each first nozzle 232 extends in the direction of the central axis of the barrel body 21, the first nozzle 232 can be installed and set up more conveniently. After the self-cleaning component 23 is installed in the barrel body 21, the first nozzle 232 can also be made as close to the inner wall of the barrel body 21 as possible to reduce the kinetic energy loss of the cleaning liquid in the process of being sprayed from the nozzle 2322 to the inner wall of the barrel body 21.
[0074] like Figure 2 and Figure 4As shown, in one embodiment of the present disclosure, a pipe joint 213 for docking with the body 1 is provided on the side of the barrel body 21 facing the main body 1, as well as a first docking portion 214 located in the inner cavity 211 of the barrel body 21 and connected to the pipe joint 213. A second docking portion 234 extending downward and connected to the diversion channel 2311 is provided on the component body 231. The first docking portion 214 is configured to connect and conduct with the second docking portion 234. Thus, during the installation of the sewage bucket 2 of the present disclosure, the pipe joint 213 on the outer side of the barrel body 21 can dock with the water injection head in the installation groove of the body 1. During the operation of the self-cleaning assembly 23, the body 1 can supply cleaning liquid to the diversion channel 2311 of the self-cleaning assembly 23 through the pipe joint 213, the first docking portion 214, and the second docking portion 234. Furthermore, the second docking portion 234 can cooperate with the first docking portion 214 to achieve bottom positioning of the component body 231 . After the cover 22 is installed, the top positioning of the component body 231 is formed to ensure that the self-cleaning assembly 23 can be positioned at a predetermined position.
[0075] Furthermore, in one embodiment of the present disclosure, the top end surfaces of the pipe joint 213 and the cover body 22 are both constructed to extend downwardly at an angle, with the pipe joint 213 and the cover body 22 having the same inclination direction, and the angle of inclination of the pipe joint 213 being greater than or equal to the angle of inclination of the top end surface of the cover body 22. Since the top end surfaces of the pipe joint 213 and the cover body 22 both extend downwardly at an angle, and the top end surfaces of the pipe joint 213 and the cover body 22 have the same inclination direction, during the installation process of the sewage bucket 2 of the present disclosure, the bottom of the sewage bucket 2 can be first placed in the mounting groove of the body 1, and then the sewage bucket 2 can be rotated upward to push the pipe joint 213 into contact with the water injection head in the mounting groove of the body 1, and the top end surface of the cover body 22 then contacts the fan unit 4, thereby completing the installation of the sewage bucket 2. Since the inclination angle of the pipe joint 213 is greater than or equal to the inclination angle of the top end surface of the cover body 22, the pipe joint 213 can be first docked with the water injection head in the installation groove of the fuselage 1, and the top end surface of the cover body 22 can then be docked with the fan unit 4, so as to facilitate the installation process of the sewage bucket 2 and prevent the pipe joint 213 from having a poor docking with the water injection head in the installation groove of the fuselage 1.
[0076] like Figure 1 As shown, in one embodiment of the present disclosure, a sewage inlet pipe 212 is provided on the barrel body 21, and the sewage inlet pipe 212 has a transverse portion 2312 extending in the transverse direction above the barrel body 21. Since the sewage inlet pipe 212 is provided on the barrel body 21 and the transverse portion 2312 extending in the transverse direction above the barrel body 21 is provided, it is convenient for dirt to enter the inner cavity 211 of the sewage barrel 2 along the sewage inlet pipe 212.
[0077] Further, such as Figure 4As shown, in one embodiment of the present disclosure, the component body 231 is constructed as an annular structure extending circumferentially along the barrel body 21, and the component body 231 is provided with a recessed portion 2313 for avoidance at the position of the transverse portion 2312; the first nozzle 232 is arranged at the bottom of the component body 231, so that the recessed portion 2313 for avoidance provided at the position of the transverse portion 2312 of the component body 231 will not affect the overall arrangement of the sewage inlet pipe 212, and the component body 231 is an annular structure extending circumferentially along the barrel body 21, and will not affect the overall structural strength of the component body 231. At the same time, the first nozzle 232 is arranged at the bottom of the component body 231, which can effectively reduce the cleaning dead corners of the inner wall of the barrel body 21.
[0078] Further, such as Figure 4 As shown, in one embodiment of the present disclosure, a downwardly extending positioning portion 235 is provided on the component body 231; a matching portion 215 that matches the positioning portion 235 is provided at a corresponding position in the inner cavity 211 of the barrel body 21; wherein the positioning portion 235 and the second docking portion 234 are configured to be located on both sides of the transverse portion 2312. In this way, the positioning portion 235 on the component body 231 and the matching portion 215 on the inner cavity 211 of the barrel body 21 can cooperate with each other, and the second docking portion 234 cooperates with the first docking portion 214, which can further achieve positioning of the component body 231 from both sides of the transverse portion 2312, ensuring that the self-cleaning assembly 23 can be installed in a predetermined position.
[0079] In one embodiment of the present disclosure, at least two second nozzles 233 are provided on the component body 231, communicating with the guide channel 2311. The at least two second nozzles 233 are configured to spray cleaning liquid at least toward the gas-liquid separation assembly 222. Thus, during operation of the self-cleaning assembly 23 of the present disclosure, the guide channel 2311 can provide cleaning liquid to each of the second nozzles 233, and the at least two second nozzles 233 can spray cleaning liquid at least toward the gas-liquid separation assembly 222, thereby cleaning the gas-liquid separation assembly 222.
[0080] Specifically, such as Figure 4 As shown, in one embodiment of the present disclosure, the component body 231 is configured as an annular structure extending circumferentially along the barrel body 21, and at least two second nozzles 233 are configured to be spaced apart and distributed on the inner circumferential wall of the component body 231. Since the at least two second nozzles 233 are spaced apart and distributed on the inner circumferential wall of the component body 231, the at least two second nozzles 233 spaced apart and distributed on the inner circumferential wall of the component body 231 can spray cleaning liquid to various locations around the circumference of the gas-liquid separation assembly 222, thereby cleaning various locations around the circumference of the gas-liquid separation assembly 222.
[0081] like Figure 4 and Figure 9As shown, in one embodiment of the present disclosure, an X-axis and a Y-axis are defined in the same plane and perpendicular to each other, wherein the X-axis direction is the front-rear direction of the cleaning device 10; a downwardly extending flow partition 2314 is provided on the component body 231, and both sides of the flow partition 2314 are constructed to extend in the Y-axis direction to cooperate with the corresponding inner wall of the barrel body 21. The two sides of the flow divider 2314 extend left and right to abut the corresponding inner walls of the barrel 21, thereby forming a seal with the corresponding inner walls of the barrel 21. When the user is using the cleaning device 10 of the present disclosure, if the entire body 1 is tilted toward the user's rear side or even lying flat, the flow divider 2314 can isolate the upper rear side of the inner cavity 211 of the sewage bucket 2 from the upper front side of the inner cavity 211 where the gas outlet is located. When the user pushes and pulls the cleaning device 10, even if the dirt is repeatedly shaken, it will be blocked by the flow divider 2314, thereby preventing dirt droplets from entering the fan unit 4 through the gas outlet and causing damage to the fan unit 4. Furthermore, the flow divider 2314 is disposed on the main body 231, so that when the main body 231 is disassembled, the flow divider 2314 can be removed simultaneously with the main body 231. Preferably, the flow divider 2314 is arc-shaped, and the distance between the two sides of the flow divider 2314 where it abuts the inner wall of the barrel 21 is smaller than the distance between the middle of the flow divider 2314 and the body 1. Thus, when the body 1 is rotated to the flat position, the end of the barrel 21 away from the body 1 is located at the bottom, and the end of the barrel 21 facing the body 1 is located at the top. The space below the two sides of the flow divider 2314 where it abuts the inner wall of the barrel 21 is larger than the space below the middle of the flow divider 2314. When the body 1 is moved back for cleaning, the larger space on both sides helps reduce surge.
[0082] Further, such as Figure 9 As shown, in another embodiment of the present disclosure, the gas-liquid separation component 222 includes a baffle 223 extending downward from the cover body 22, and two baffles 2314 are provided on the component body 231, which are located on opposite sides of the baffle 223; the baffle 2314 is constructed to extend from the position of the baffle 223 in the Y-axis direction to cooperate with the corresponding inner wall of the barrel body 21. Since the gas-liquid separation component 222 includes a baffle 223 extending downward from the cover body 22, the two baffles 2314 are respectively located on opposite sides of the baffle 223, and extend from the position of the baffle 223 in the Y-axis direction to abut against the corresponding inner wall of the barrel body 21, it can be ensured that the baffle 223 and the baffle 2314 form an integral baffle member in the Y-axis direction, thereby isolating the upper rear side of the inner cavity 211 of the sewage bucket 2 from the upper front side of the inner cavity 211 where the gas outlet and the dirt inlet are located, which can prevent dirty liquid droplets from entering the fan unit 4 through the gas outlet and causing damage to the fan unit 4, and can also ensure that the dirt flows along the baffle 223 into the inner cavity 211 of the sewage bucket 2.
[0083] Application Scenario
[0084] The present disclosure provides a cleaning device 10, including a body 1 and a sewage bucket 2, wherein the sewage bucket 2 includes a barrel body 21, a self-cleaning component 23 and a cover body 22; wherein the barrel body 21 is constructed to enclose an inner cavity 211 with an opening; the self-cleaning component 23 is constructed to be detachably mounted on the upper part of the barrel body 21, and is configured to output cleaning liquid to at least clean the inner wall of the barrel body 21; a gas pipeline 221 and a gas-liquid separation component 222 are provided on the cover body 22; the cover body 22 is detachably mounted on the opening of the barrel body 21, and is located in the disassembly and assembly path of the self-cleaning component 23.
[0085] In this way, in the cleaning device 10 of the present invention, the inner cavity 211 in the barrel body 21 can be used to accommodate dirt, and during operation, the gas pipeline 221 on the cover body 22 of the sewage bucket 2 can be connected to the fan unit 4, and the fan unit 4 can form a negative pressure in the inner cavity 211 of the barrel body 21, thereby sucking the dirt on the working surface into the inner cavity 211. Since the gas-liquid separation component 222 is provided on the cover body 22, it can prevent dirty liquid droplets from entering the fan unit 4 from the cover body 22.
[0086] When the cleaning device 10 of the present disclosure is used in conjunction with a cleaning base station 20 capable of automatic sewage discharge, the cleaning device 10 of the present disclosure can be placed on the cleaning base station 20, and then the dirt in the sewage bucket 2 is automatically discharged into the cleaning base station 20. After the dirt is discharged, the self-cleaning component 23 can be used to output cleaning liquid to at least clean the inner wall of the barrel body 21, thereby cleaning the residual dirt on the inner wall of the sewage bucket 2. The user does not need to manually clean the interior of the sewage bucket 2, which helps to reduce the user's usage burden and greatly improves the user experience.
[0087] Moreover, since the self-cleaning component 23 is detachably mounted on the upper portion of the barrel body 21, the cover body 22 is detachably mounted on the opening of the barrel body 21, and is located in the disassembly and assembly path of the self-cleaning component 23, when assembling the sewage barrel 2 of the present disclosure, it is only necessary to place the self-cleaning component 23 on the upper portion of the barrel body 21, and then install the cover body 22 on the opening of the barrel body 21.
[0088] When there is stubborn dirt that is difficult to remove in the barrel body 21, the user can remove the sewage barrel 2 from the body 1, and then remove the cover body 22 and the self-cleaning component 23 from the barrel body 21 in turn, and rinse the barrel body 21, the cover body 22 and the self-cleaning component 23 respectively to remove the stubborn dirt on the inner cavity 211 of the sewage barrel 2, thereby achieving deep cleaning of the various components of the sewage barrel 2, preventing bacteria from growing in the sewage barrel 2, and effectively avoiding hygiene problems.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
