Description

Technical Field

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

[0002] Cleaning devices in related technologies often require a wastewater tank to collect wastewater discharged from the cleaning drum. However, the traditional external or freestanding design of the wastewater tank often occupies a large space in the cleaning device, hindering its miniaturization and portability. Further analysis reveals that if the wastewater tank is placed inside the cleaning drum, the cleaning drum must rotate relative to the surface to be cleaned. If the wastewater tank rotates with the cleaning drum, the wastewater inside will slosh due to centrifugal force, potentially causing leakage and affecting the performance of the cleaning device. Utility Model Content

[0003] In view of this, this application provides a cleaning device that can be miniaturized and can prevent sewage leakage from the sewage tank.

[0004] This application provides a cleaning device, which includes: a frame, a cleaning component, and a collection component. The cleaning component includes a cleaning roller rotatably connected to the frame and has a receiving cavity. The collection component includes a wastewater tank located within the receiving cavity and connected to the frame. The cleaning roller and the wastewater tank are rotatably connected, and the wastewater tank is used to collect wastewater discharged by the cleaning roller.

[0005] Furthermore, the sewage tank includes a first cylindrical section and a second cylindrical section connected together. The end of the first cylindrical section opposite to the second cylindrical section is rotatably connected to the cleaning roller. The end of the second cylindrical section opposite to the first cylindrical section is connected to the frame. The second cylindrical section is capable of elastic deformation in the axial and / or radial direction of the sewage tank.

[0006] Furthermore, the bottom of the first cylindrical part is provided with a first positioning part, and the bottom wall of the receiving cavity of the cleaning roller is provided with a second positioning part, wherein the first positioning part and the second positioning part are in a concave-convex fit.

[0007] Furthermore, the collecting assembly also includes a rotating support member, which is disposed between the first positioning part and the second positioning part. The rotating support member is connected to the first positioning part, and the second positioning part is detachably connected to the rotating support member.

[0008] Furthermore, the distance between the outer peripheral wall of the sewage tank and the inner peripheral wall of the accommodating cavity of the cleaning roller is greater than zero and less than or equal to a first preset distance, so that the cleaning roller remains spaced apart from the outer peripheral wall of the sewage tank during rotation.

[0009] Furthermore, along the arrangement direction of the first cylindrical portion and the second cylindrical portion, the second positioning portion includes a connected positioning sub-part and a guide sub-part. The positioning sub-part is detachably connected to the rotating support member. The radial dimension of the guide sub-part gradually decreases from one end of the guide sub-part closer to the positioning sub-part toward the end farther from the positioning sub-part.

[0010] Furthermore, the frame includes a main body, a first side, and a second side. The first side and the second side are respectively connected to opposite sides of the main body and bent toward the same side of the main body. The opposite ends of the cleaning roller are rotatably connected to the first side and the second side, respectively. The cleaning device also includes a squeezing strip and a sealing strip. The squeezing strip and the sealing strip are located on the same side of the cleaning roller and are respectively connected to the main body. With the cooperation of the squeezing strip and the sealing strip, the wastewater from the cleaning roller flows to the wastewater cylinder.

[0011] Furthermore, the frame also includes a mounting portion, which is located on the side of the first side facing the second side; the mounting portion has a preset channel, through which the wastewater from the cleaning roller flows to the wastewater cylinder with the cooperation of the squeezing strip and the sealing strip; wherein, the collection assembly also includes a fixing strap, the second cylinder is sleeved on the outer periphery of the mounting portion, and the fixing strap is sleeved on the outer periphery of the second cylinder to fix the relative position of the second cylinder and the frame; or, the second cylinder and the mounting portion are glued together to fix the relative position of the second cylinder and the frame; or, the second cylinder and the mounting portion are threaded together to fix the relative position of the second cylinder and the frame.

[0012] Furthermore, a flow channel is provided on the side of the first side away from the second side, the flow channel is arranged adjacent to the cleaning roller, and the flow channel is used to guide the sewage of the cleaning roller to the preset channel; the cleaning device also includes a cover plate assembly, the cover plate assembly is sealed to the side of the first side away from the second side.

[0013] Furthermore, the cover assembly includes a sealing cover and a flip cover. The sealing cover closes the flow groove and is sealed to the first side. The flip cover is detachably connected to the sealing cover and is configured to correspond to the preset channel.

[0014] In this application, the cleaning roller is rotatably connected to the frame. When the cleaning device is used to clean the surface to be cleaned, the cleaning roller rotates relative to the frame and the surface under the action of friction between the cleaning roller and the surface to be cleaned, thereby achieving the cleaning function. The wastewater tank is located within the receiving cavity of the cleaning roller and is used to collect the wastewater discharged by the cleaning roller. The wastewater tank can collect the wastewater discharged during the rolling process in a timely manner to prevent wastewater from flowing back to the surface to be cleaned and causing secondary pollution, thus improving the cleaning effect of the cleaning device. Furthermore, compared to external or independent designs of the wastewater tank, the wastewater tank in this application makes full use of the internal space of the cleaning roller, without increasing the horizontal or vertical dimensions of the cleaning device. This facilitates the miniaturization of the cleaning device, allowing it to easily maneuver in confined spaces and improving its cleaning coverage. Furthermore, since the wastewater tank is connected to the frame and the cleaning roller is rotatably connected to the wastewater tank, when the cleaning roller rotates relative to the surface to be cleaned, the position of the wastewater tank relative to the frame remains fixed, and the wastewater tank does not rotate synchronously with the cleaning roller. This effectively alleviates the violent shaking of the wastewater inside the tank caused by centrifugal force and reduces the continuous impact of the wastewater on the sealing structure at the opening of the wastewater tank. This allows the sealing structure at the opening of the wastewater tank to maintain its sealing performance, preventing the wastewater from being discharged during the operation of the cleaning device. Once wastewater leaks out, it not only contaminates the already cleaned area, creating a secondary cleaning burden, but may also seep into the core components inside the cleaning device, causing corrosion. The cleaning device provided in this application effectively prevents wastewater from leaking out of the wastewater tank during the cleaning process, resulting in better cleaning effect, longer service life, and better performance.

[0029] Cleaning devices in related technologies often require a wastewater tank to collect wastewater discharged from the cleaning drum. However, the traditional external or freestanding design of the wastewater tank often occupies a large space in the cleaning device, hindering its miniaturization and portability. Further analysis reveals that if the wastewater tank is placed inside the cleaning drum, the cleaning drum must rotate relative to the surface to be cleaned. If the wastewater tank rotates with the cleaning drum, the wastewater inside will experience violent shaking due to centrifugal force; the faster the rotation speed and the larger the wastewater volume, the greater the shaking amplitude. This violent shaking will continuously impact the sealing structure between the wastewater tank and the cleaning drum, potentially leading to accelerated wear of the sealing structure or widening of the sealing gap. Simultaneously, the instantaneous pressure generated by the shaking will disrupt the static equilibrium of the wastewater inside the tank, making it easy for the wastewater to breach the seal and leak out through the gaps. Once sewage leaks out, it will not only contaminate the already cleaned area and create a secondary cleaning burden, but may also seep into the core components of the cleaning device, such as circuits and transmissions, causing rust, short circuits and other malfunctions. Ultimately, this will seriously affect the cleaning effect, service life and operational stability of the cleaning device, and have a significant negative impact on its overall performance.

[0030] Please see Figures 1 to 4This application provides a cleaning device 100, which includes a frame 110, a cleaning component 120, and a collection component 130. The cleaning component 120 includes a cleaning roller 121, which is rotatably connected to the frame 110 and has a receiving cavity 122. The collection component 130 includes a wastewater cylinder 131, which is located within the receiving cavity 122 and connected to the frame 110. The cleaning roller 121 and the wastewater cylinder 131 are rotatably connected, and the wastewater cylinder 131 is used to collect wastewater discharged from the cleaning roller 121.

[0031] Understandably, when the cleaning device 100 is used to clean the surface to be cleaned, the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned in order to clean the surface to be cleaned.

[0032] Understandably, in the terminology of this application, "surface to be cleaned" can be, but is not limited to, floors, countertops, etc.

[0033] Understandably, the cleaning roller 121 has a receiving cavity 122, and the sewage cylinder 131 is located in the receiving cavity 122. Alternatively, the cleaning roller 121 can be arranged around the outer periphery of the sewage cylinder 131.

[0034] Understandably, the connection between the sewage tank 131 and the frame 110 can be such that the relative positions of the sewage tank 131 and the frame 110 are fixed.

[0035] Understandably, the cleaning roller 121 and the sewage cylinder 131 are rotatably connected. Specifically, the sewage cylinder 131 can rotate relative to the cleaning roller 121. Therefore, when the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned, the sewage cylinder 131 does not rotate synchronously with the cleaning roller 121.

[0036] In this embodiment, the cleaning roller 121 is rotatably connected to the frame 110. When the cleaning device 100 is used to clean the surface to be cleaned, the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned under the action of friction between the cleaning roller 121 and the surface to be cleaned, thereby achieving the cleaning function of the surface to be cleaned. The wastewater tank 131 is located within the receiving cavity 122 of the cleaning roller 121, and the wastewater tank 131 is used to collect the wastewater discharged by the cleaning roller 121. The wastewater tank 131 can collect the wastewater discharged by the cleaning roller 121 during its rotation in a timely manner, to avoid wastewater flowing back to the surface to be cleaned and causing secondary pollution, thus improving the cleaning effect of the cleaning device 100 on the surface to be cleaned. Furthermore, compared to the external or independent design of the sewage tank 131, the sewage tank 131 of this application makes full use of the space inside the cleaning roller 121 without increasing the horizontal or vertical dimensions of the cleaning device 100. This is conducive to the miniaturization design of the cleaning device 100, allowing the cleaning device 100 to easily move through narrow spaces and improve the cleaning coverage of the cleaning device 100. Furthermore, since the sewage tank 131 is connected to the frame 110 and the cleaning roller 121 is rotatably connected to the sewage tank 131, when the cleaning roller 121 rotates relative to the surface to be cleaned, the position of the sewage tank 131 and the frame 110 is relatively fixed, and the sewage tank 131 does not rotate synchronously with the cleaning roller 121. This can effectively alleviate the violent shaking of the sewage in the sewage tank 131 caused by centrifugal force, and can also reduce the continuous impact of the sewage in the sewage tank 131 on the sealing structure at the opening of the sewage tank 131. This allows the sealing structure at the opening of the sewage tank 131 to continuously perform its sealing performance, so as to prevent the sewage in the sewage tank 131 from being discharged when the cleaning device 100 is working. Once sewage leaks out, it will not only contaminate the already cleaned area and create a secondary cleaning burden, but may also seep into the core components inside the cleaning device 100, causing corrosion of the components. The cleaning device 100 provided in this application can effectively prevent sewage in the sewage tank 131 from leaking out during the cleaning process, so that the cleaning device 100 has a better cleaning effect, a longer service life and better performance.

[0037] Understandably, the cleaning device 100 in this embodiment of the application achieves rotation through the friction between the cleaning roller 121 and the surface to be cleaned, thereby cleaning the surface without the need for an additional drive motor.

[0038] Optionally, the cleaning device 100 further includes a water tank 170, which is used to inject water into the cleaning roller 121 to wet the cleaning roller 121 in order to clean the surface to be cleaned.

[0039] Please see also Figure 5 and Figure 6 In some embodiments, the sewage tank 131 includes a first cylindrical portion 132 and a second cylindrical portion 137 connected together. The end of the first cylindrical portion 132 opposite to the second cylindrical portion 137 is rotatably connected to the cleaning roller 121. The end of the second cylindrical portion 137 opposite to the first cylindrical portion 132 is connected to the frame 110. The second cylindrical portion 137 is capable of elastic deformation in the axial and / or radial direction of the sewage tank 131.

[0040] Understandably, the second cylindrical portion 137 is capable of elastic deformation in the axial and / or radial direction of the sewage cylinder 131. This can mean that the length of the second cylindrical portion 137 can be extended or shortened in the axial direction of the sewage cylinder 131; and / or, the length of the second cylindrical portion 137 can be extended or shortened in the radial direction of the sewage cylinder 131.

[0041] Understandably, the axial direction of the sewage cylinder 131 is parallel to the arrangement direction of the first cylinder portion 132 and the second cylinder portion 137.

[0042] Understandably, the radial direction of the sewage tank 131 is perpendicular to the axial direction of the sewage tank 131.

[0043] In this embodiment, the second cylindrical portion 137 is capable of elastic deformation in the axial and / or radial direction of the sewage cylinder 131, so that the length of the sewage cylinder 131 can be extended or shortened along the axial and / or radial direction. Furthermore, the end of the second cylindrical portion 137 opposite to the first cylindrical portion 132 is connected to the frame 110. During the installation of the sewage cylinder 131 into the cleaning device 100, the second cylindrical portion 137 of the sewage cylinder 131 is first connected to the frame 110, and then its length is compressed to provide space for the first cylindrical portion 132 to extend into the cleaning roller 121. After the first cylindrical portion 132 extends into the cleaning roller 121, the second cylindrical portion 137 deforms and recovers, so that the end of the first cylindrical portion 132 opposite to the second cylindrical portion 137 is rotatably connected to the cleaning roller 121, thereby placing the sewage cylinder 131 within the receiving cavity 122 of the cleaning roller 121. In this embodiment, through the structural design of the first cylindrical portion 132 and the second cylindrical portion 137, the first cylindrical portion 132, with its better rigidity, can improve the structural stability of the rolling connection between the sewage cylinder 131 and the cleaning roller 121, thereby ensuring the function of the sewage cylinder 131 in containing sewage. The second cylindrical portion 137, which can elastically deform along the axial and / or radial direction of the sewage cylinder 131, can reduce the difficulty of installing the sewage cylinder 131 into the receiving cavity 122 of the cleaning roller 121, thereby simplifying the installation difficulty of the cleaning device 100 and enabling the cleaning device 100 to have better performance.

[0044] Optionally, the second cylindrical portion 137 satisfies any one of the following conditions: the second cylindrical portion 137 is telescopic in the axial and / or radial direction of the sewage cylinder 131; the second cylindrical portion 137 is deformable in the axial and / or radial direction of the sewage cylinder 131; the second cylindrical portion 137 is displaceable in the axial and / or radial direction of the sewage cylinder 131.

[0045] Optionally, in some embodiments, the first cylindrical portion 132 is a rigid cylindrical portion, and the second cylindrical portion 137 is a flexible cylindrical portion. The material of the rigid cylindrical portion includes, but is not limited to, metal, rigid plastic tubing, etc. The material of the flexible cylindrical portion includes, but is not limited to, rubber, flexible plastic tubing, etc.

[0046] Optionally, in some embodiments, the first cylindrical portion 132 and the second cylindrical portion 137 are both rigid cylindrical portions, and the first cylindrical portion 132 and the second cylindrical portion 137 are slidably telescopic.

[0047] Please see also Figure 7 In some embodiments, the bottom of the first cylindrical portion 132 is provided with a first positioning portion 133, and the bottom wall of the receiving cavity 122 of the cleaning roller 121 is provided with a second positioning portion 134, wherein the first positioning portion 133 and the second positioning portion 134 are in a concave-convex fit.

[0048] Understandably, the bottom of the first cylindrical portion 132 is the end of the first cylindrical portion 132 that is opposite to the second cylindrical portion 137.

[0049] Understandably, the first positioning part 133 and the second positioning part 134 are in a concave-convex fit. In some embodiments, the first positioning part 133 is a convex part and the second positioning part 134 is a concave part; in other embodiments, the first positioning part 133 is a concave part and the second positioning part 134 is a convex part.

[0050] In this embodiment, a first positioning part 133 is provided at the bottom of the first cylindrical part 132, and a second positioning part 134 is provided on the bottom wall of the receiving cavity 122 of the cleaning roller 121. When the end of the second cylindrical part 137 opposite to the first cylindrical part 132 is connected to the frame 110, and the first cylindrical part 132 extends into the receiving cavity 122, the first positioning part 133 and the second positioning part 134 engage in a concave-convex fit to secure the sewage cylinder 131 within the cleaning roller 121, thereby improving the stability of the sewage cylinder 131 installed on the cleaning roller 121. When the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned, the sewage cylinder 131 remains securely positioned within the receiving cavity 122, allowing it to collect sewage. The cleaning device 100 thus exhibits good performance.

[0051] In some embodiments, the collecting assembly 130 further includes a rotating support 135, which is disposed between the first positioning part 133 and the second positioning part 134. The rotating support 135 is connected to the first positioning part 133, and the second positioning part 134 is detachably connected to the rotating support 135.

[0052] Optionally, in some embodiments, the rotating support 135 is a bearing; in other embodiments, the rotating support 135 is a shaft assembly.

[0053] Understandably, the rotating support 135 is connected to the first positioning part 133, and the second positioning part 134 is detachably connected to the rotating support 135. Specifically, the rotating support 135 is fixed to the first positioning part 133, and the second positioning part can be detachably inserted into the rotating support 135.

[0054] In the terminology of this application, the second positioning part 134 is detachably connected to the rotating support member 135. This means that when the sewage cylinder 131 is inserted into the receiving cavity 122 of the cleaning roller 121, the second positioning part 134 is inserted into the rotating support member 135 to achieve a rotatable connection between the sewage cylinder 131 and the cleaning roller 121. When the sewage cylinder 131 is withdrawn from the receiving cavity 122 of the cleaning roller 121, the second positioning part 134 separates from the rotating support member 135.

[0055] In this embodiment, the rotating support 135 is located between the first positioning part 133 and the second positioning part 134. The rotating support 135 is connected to the first positioning part 133. In other words, the rotating support 135 is installed on the sewage tank 131. When the sewage tank 131 is placed in the receiving cavity 122 of the cleaning roller 121, the second positioning part is inserted into the rotating support 135 to achieve a rotating connection between the sewage tank 131 and the cleaning roller 121. When the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned, the sewage tank 131 does not rotate synchronously with the cleaning roller 121 to avoid the sewage collected in the sewage tank 131 from leaking out of the sewage tank 131 due to violent shaking caused by centrifugal force, thus giving the cleaning device 100 better performance. Furthermore, the second positioning part 134 is detachably connected to the rotating support member 135. When the sewage cylinder 131 is withdrawn from the receiving cavity 122 of the cleaning roller 121, it facilitates the rapid separation of the second positioning part 134 and the rotating support member 135, thereby separating the sewage cylinder 131 from the cleaning roller 121 and making it easier for users to disassemble and clean the sewage cylinder 131. In this embodiment, the rotating support member 135, the first positioning part 133, and the second positioning part 134 cooperate with each other, making it easy to install and separate the sewage cylinder 131 from the cleaning roller 121, thus improving the performance of the cleaning device 100.

[0056] In some embodiments, the distance between the outer peripheral wall of the sewage cylinder 131 and the inner peripheral wall of the accommodating cavity 122 of the cleaning roller 121 is greater than zero and less than or equal to a first preset distance, so that the cleaning roller 121 remains spaced apart from the outer peripheral wall of the sewage cylinder 131 during rotation.

[0057] Understandably, in the terminology of this application, "first preset distance" is the limit distance between the inner peripheral wall of the cleaning roller 121 and the outer peripheral wall of the sewage tank 131 when the cleaning roller 121 does not contact the sewage tank 131 during rotation and the sewage tank 131 does not shake significantly inside the cleaning roller 121. This application does not limit the specific value of "first preset distance".

[0058] In this embodiment, the distance between the outer peripheral wall of the sewage cylinder 131 and the inner peripheral wall of the receiving cavity 122 of the cleaning roller 121 is greater than zero and less than or equal to a first preset distance. On the one hand, when the cleaning roller 121 rotates relative to the surface to be cleaned and the frame 110, the inner peripheral wall of the receiving cavity 122 and the outer peripheral wall of the sewage cylinder 131 are spaced apart. In other words, when the cleaning roller 121 rotates relative to the sewage cylinder 131, there is a certain distance between the sewage cylinder 131 and the cleaning roller 121, which can prevent the sewage cylinder 131 and the cleaning roller 121 from colliding with each other, avoid wear on the sewage cylinder 131 and / or the cleaning roller 121, and at the same time avoid the excessive sliding friction between the sewage cylinder 131 and the cleaning roller 121 from hindering the rotation of the cleaning roller 121, thereby improving the performance of the cleaning device 100. On the other hand, since the sewage cylinder 131 includes a first cylinder portion 132 and a second cylinder portion 137, and the second cylinder portion 137 is capable of compressive deformation in the axial direction of the sewage cylinder 131, if the distance between the outer peripheral wall of the sewage cylinder 131 and the inner peripheral wall of the receiving cavity 122 of the cleaning roller 121 is too large, the sewage cylinder 131 may violently shake within the receiving cavity 122 during the rotation of the cleaning roller 121, reducing the structural stability of the sewage cylinder 131 disposed within the cleaning roller 121. In this embodiment, the distance between the outer peripheral wall of the sewage cylinder 131 and the inner peripheral wall of the receiving cavity 122 of the cleaning roller 121 is greater than zero and less than or equal to a first preset distance. Therefore, during the rotation of the cleaning roller 121, the violent shaking of the sewage cylinder 131 within the receiving cavity 122 can be effectively alleviated, and the sewage cylinder 131 disposed within the cleaning roller 121 has better structural stability.

[0059] In some embodiments, along the arrangement direction of the first cylindrical portion 132 and the second cylindrical portion 137, the second positioning portion 134 includes a connected positioning sub-portion 1341 and a guide sub-portion 1342. The positioning sub-portion 1341 is detachably connected to the rotating support member 135. The radial dimension of the guide sub-portion 1342 gradually decreases from one end of the guide sub-portion 1341 close to the positioning sub-portion 1341 toward the end away from the positioning sub-portion 1341.

[0060] Understandably, the maximum radial dimension of the guide sub-part 1342 is less than or equal to the radial dimension of the positioning sub-part 1341.

[0061] In this embodiment, the second positioning part 134 includes a connected positioning sub-part 1341 and a guide sub-part 1342, and the guide sub-part 1342 is disposed further away from the bottom wall of the receiving cavity 122 of the cleaning roller 121. When the second cylindrical part 137 of the sewage cylinder 131 is connected to the frame 110 at the end away from the first cylindrical part 132, the first cylindrical part 132 of the sewage cylinder 131 extends into the receiving cavity 122 of the cleaning roller 121. The bottom of the first cylindrical part 132 first contacts the guide sub-part 1342. The end of the guide sub-part 1342 near the positioning sub-part 1341 faces away from the positioning sub-part 1341. The radial dimension of the guide sub-part 1342 gradually decreases. The guide sub-part 1342 can be used to guide the second positioning part 134 to be inserted into the rotating support member 135, thereby improving the efficiency of the connection between the sewage cylinder 131 and the cleaning roller 121. Furthermore, the guide sub-part 1342 is engaged with the rotating support member 135 to improve the stability of the connection between the sewage tank 131 and the cleaning roller 121. This embodiment improves the efficiency and accuracy of the docking between the sewage tank 131 and the cleaning roller 121 through detailed design of the second positioning part 134, which is beneficial to improving the efficiency of installing the sewage tank 131 onto the cleaning roller 121.

[0062] Please see also Figure 8 In some embodiments, the frame 110 includes a main body 111, a first side 112, and a second side 113. The first side 112 and the second side 113 are respectively connected to opposite sides of the main body 111 and bent toward the same side of the main body 111. The opposite ends of the cleaning roller 121 are respectively rotatably connected to the first side 112 and the second side 113. The cleaning device 100 also includes a squeezing strip 140 and a sealing strip 150. The squeezing strip 140 and the sealing strip 150 are located on the same side of the cleaning roller 121. The squeezing strip 140 and the sealing strip 150 are respectively connected to the main body 111. With the cooperation of the squeezing strip 140 and the sealing strip 150, the wastewater of the cleaning roller 121 flows to the wastewater cylinder 131.

[0063] Understandably, the main body 111, the first side portion 112, and the second side portion 113 are arranged in a "C" shape.

[0064] Understandably, the water-squeezing strip 140, the water-sealing strip 150, the cleaning roller 121, and the main body 111 form a water channel 151, which is located on one side of the cleaning roller 121.

[0065] In this embodiment, the first side portion 112 and the second side portion 113 are rotatably connected to opposite ends of the cleaning roller 121, the water-squeezing strip 140 and the water-sealing strip 150 are located on the same side of the cleaning roller 121, and the water-squeezing strip 140 and the water-sealing strip 150 are respectively connected to the body portion 111. The water-squeezing strip 140, the water-sealing strip 150, the cleaning roller 121 and the body portion 111 form a water channel 151, which is located on one side of the cleaning roller 121. As the cleaning roller 121 rotates relative to the frame 110 and the surface to be cleaned, the part of the cleaning roller 121 in contact with the surface to be cleaned cleans the surface. At the same time, under the action of the squeezing strip 140 and the sealing strip 150, the squeezing strip 140 squeezes the sewage in the cleaning roller 121, and the sealing strip 150 blocks the squeezed sewage, so that the sewage in the cleaning roller 121 can flow to the sewage tank 131 through the water channel 151. The sewage tank 131 collects the sewage in time to prevent the sewage from re-entering the surface to be cleaned and causing secondary pollution.

[0066] Understandably, the waterway 151 and the sewage tank 131 are spaced apart, and the sewage in the waterway 151 flows to the sewage tank 131 from at least one of the first side portion 112 and the second side portion 113.

[0067] Optionally, in some embodiments, the opposite ends of the squeezing strip 140 are rotatably connected to the first side 112 and the second side 113, respectively. The squeezing strip 140 abuts against the cleaning roller 121, so that when the cleaning roller 121 rotates, the squeezing strip 140 rotates relative to the cleaning roller 121.

[0068] Specifically, when the cleaning roller 121 rotates clockwise, the dewatering strip 140 rotates counterclockwise; when the cleaning roller 121 rotates counterclockwise, the dewatering strip 140 rotates clockwise.

[0069] In some embodiments, the frame 110 further includes a mounting portion 114, which is disposed on the side of the first side portion 112 facing the second side portion 113; the collection assembly 130 further includes a fixing strap 136, the second cylindrical portion 137 is sleeved on the outer periphery of the mounting portion 114, and the fixing strap 136 is sleeved on the outer periphery of the second cylindrical portion 137 to fix the relative position of the second cylindrical portion 137 and the frame 110; the mounting portion 114 has a preset channel 115, and with the cooperation of the squeezing strip 140 and the sealing strip 150, the wastewater of the cleaning roller 121 flows to the wastewater cylinder 131 through the preset channel 115.

[0070] In this embodiment, the mounting portion 114 protrudes from the side of the first side portion 112 facing the second side portion 113. The mounting portion 114 provides a fulcrum for the installation of the second cylindrical portion 137 of the sewage tank 131. During the installation of the sewage tank 131 onto the cleaning device 100, the end of the second cylindrical portion 137 facing away from the first cylindrical portion 132 is first fitted onto the outer periphery of the mounting portion 114, and then secured to the outer periphery of the second cylindrical portion 137 and the mounting portion 114 by a fixing strap 136, thereby fixing the relative position of the second cylindrical portion 137 and the frame 110 and improving the structural stability of the sewage tank 131 connected to the frame 110. Furthermore, the mounting portion 114 has a preset channel 115. When the second cylindrical portion 137 is fitted onto the outer periphery of the mounting portion 114, the preset channel 115 is at least partially located inside the second cylindrical portion 137, thereby achieving communication between the preset channel 115 and the interior of the sewage tank 131. When the cleaning device 100 performs a cleaning task and the cleaning roller 121 rotates relative to the surface to be cleaned and the frame 110, with the cooperation of the squeezing strip 140 and the sealing strip 150, the wastewater generated by the cleaning roller 121 enters the preset channel 115 from the first side 112 and flows to the wastewater tank 131 to collect the wastewater. This avoids secondary contamination of the surface to be cleaned by the wastewater and improves the performance of the cleaning device 100. Furthermore, in the cleaning device 100 provided in this application, the fixing strap 136 can also seal the gap between the mounting part 114 and the second cylinder part 137 to prevent wastewater in the wastewater tank 131 from flowing out through the gap between the mounting part 114 and the second cylinder part 137. The connection between the wastewater tank 131 and the frame 110 has good sealing performance.

[0071] Optionally, in some embodiments, the second cylinder 137 and the mounting portion 114 are connected by adhesive to fix the relative position of the second cylinder 137 and the frame 110. This connection method is simple, and the connection between the sewage cylinder 131 and the frame 110 has good sealing performance.

[0072] Alternatively, in some other embodiments, the second cylindrical portion 137 and the mounting portion 114 are connected by threads to fix the relative position of the second cylindrical portion 137 and the frame 110. This connection method is simple, and the connection between the sewage cylinder 131 and the frame 110 has good sealing performance.

[0073] Optionally, in some embodiments, the external thread of the second cylindrical portion 137 is threadedly connected to the internal thread of the mounting portion 114, in other words, the mounting portion 114 is sleeved on the outer periphery of the second cylindrical portion 137; in other embodiments, the internal thread of the second cylindrical portion 137 is threadedly connected to the external thread of the mounting portion 114, in other words, the second cylindrical portion 137 is sleeved on the outer periphery of the mounting portion 114.

[0074] In some embodiments, the first side 112 is provided with a flow channel 116 on the side opposite to the second side 113. The flow channel 116 is disposed adjacent to the cleaning roller 121 and is used to guide the wastewater of the cleaning roller 121 to the preset channel 115. The cleaning device 100 also includes a cover plate assembly 160, which is sealed to the side of the first side 112 opposite to the second side 113.

[0075] Understandably, the side of the cleaning roller 121 away from the receiving cavity 122, the flow channel 116, the preset channel 115, and the sewage cylinder 131 are connected in sequence.

[0076] In this embodiment, a flow channel 116 is provided on the side of the first side 112 opposite to the second side 113. The flow channel 116 is arranged adjacent to the cleaning roller 121. When the cleaning device 100 performs a cleaning task and the cleaning roller 121 rotates relative to the surface to be cleaned and the frame 110, the wastewater from the cleaning roller 121 is squeezed out and flows through the flow channel 116 to the preset channel 115 with the cooperation of the squeezing strip 140 and the sealing strip 150. Further, the wastewater enters the wastewater tank 131 through the preset channel 115, and the wastewater tank 131 is used to collect the wastewater. The cleaning device 100 also includes a cover plate assembly 160, which is sealed to the side of the first side 112 opposite to the second side 113 to block the connection between the flow channel 116 and the outside, preventing the wastewater squeezed out from the cleaning roller 121 from directly splashing to the outside and contaminating the surface to be cleaned, thereby improving the performance of the cleaning device 100.

[0077] In some embodiments, the cover assembly 160 includes a sealing cover 161 and a flip cover 162. The sealing cover 161 closes the flow groove 116 and is sealed to the first side portion 112. The flip cover 162 is detachably connected to the sealing cover 161 and is configured to correspond to the preset channel 115.

[0078] In this embodiment, the cover assembly 160 includes a sealing cover 161 and a flip cover 162. The sealing cover 161 closes the flow channel 116 and is sealed to the first side portion 112 to block the connection between the flow channel 116 and the outside, preventing wastewater squeezed out from the cleaning roller 121 from directly splashing to the outside and contaminating the surface to be cleaned. Further, the flip cover 162 is configured corresponding to the preset channel 115. The flip cover 162 is detachably connected to the sealing cover 161, allowing the flip cover 162 to open or close the preset channel 115, thereby opening or closing the wastewater tank 131. Specifically, when it is necessary to pour out the wastewater in the wastewater tank 131, the flip cover 162 is separated from the sealing cover 161 to open the preset channel 115, thus opening the wastewater tank 131 for easy wastewater pouring. When there is no need to empty the sewage, the flip cover 162 is connected to the sealing cover 161 to prevent sewage from leaking from the sewage tank 131 and causing secondary contamination of the surface to be cleaned. Compared to the solution where the sealing cover 161 and the flip cover 162 are integrally formed, in this embodiment, when it is necessary to empty the sewage in the sewage tank 131, only the flip cover 162 needs to be opened to achieve the purpose, without having to remove the sealing cover 161 from the first side 112, which improves the efficiency of emptying the sewage in the sewage tank 131 and is conducive to improving cleaning efficiency.

[0079] Specifically, in some embodiments, one end of the flip cover 162 is rotatably connected to the sealing cover 161, and the other end of the flip cover 162 is detachably connected to the sealing cover 161.

[0080] In this embodiment, one end of the flip cover 162 is rotatably connected to the sealing cover plate 161, and the flip cover 162 is configured corresponding to the preset channel 115. Therefore, the flip cover 162 can be used to open or close the preset channel 115, thereby opening or closing the sewage tank 131. Specifically, when it is necessary to pour out the sewage in the sewage tank 131, the preset channel 115 is opened by rotating the flip cover 162 and the sealing cover plate 161, thus opening the sewage tank 131 for easy sewage pouring. Compared to a solution where the sealing cover plate 161 and the flip cover 162 are integrally formed, in this embodiment, when it is necessary to pour out the sewage in the sewage tank 131, only the flip cover 162 needs to be opened to achieve the purpose, without needing to remove the sealing cover plate 161 from the first side 112, simplifying the efficiency of pouring out the sewage in the sewage tank 131 and improving cleaning efficiency.

[0081] Specifically, in some embodiments, both opposite ends of the flip cover 162 are detachably connected to the sealing cover plate 161. For example, the flip cover 162 is made of a soft material to achieve connection with the sealing cover plate 161.

[0082] Optionally, the cover assembly 160 further includes a sealing element 163, which is connected to the side of the flip cover 162 facing the preset channel 115. The sealing cover 161 has a locking hole (not shown in the figure), and the sealing element 163 is locked in the locking hole. The surface of the flip cover 162 with the sealing element 163 abuts against the surface of the sealing cover 161 facing the flip cover 162. The sealing element 163 is used to achieve a sealed connection between the flip cover 162 and the sealing cover 161.

[0083] Understandably, the locking hole is connected to the preset channel 115.

[0084] When the flip cover 162 is closed relative to the sealing cover 161, the sealing member 163 and the flip cover 162 block the locking hole to prevent sewage flowing into the flow channel 116 from being directly discharged to the outside. When the flip cover 162 is opened relative to the sealing cover 161, the sealing member 163 is connected to the flip cover 162 to open the locking hole and open the preset channel 115, thereby facilitating the user to discharge sewage from the sewage tank 131.

[0085] Optionally, the cleaning device 100 further includes a trash box 180, the two opposite ends of which are rotatably connected to the frame 110, for containing the trash carried by the cleaning roller 121 during the cleaning process.
