Detailed Implementation

[0032] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0033] In view of this, in order to solve the above problems, please refer to the following: Figures 1-9 This embodiment provides a cleaning device 1, which includes a housing 11, a brush roller 12, and a fixing assembly 13. The housing 11 has a receiving space 111; at least a portion of the brush roller 12 is disposed within the receiving space 111, and the brush roller 12 has a hole 1211; the fixing assembly 13 includes a fixing seat 131, a guide shaft 132, and a sliding member 133. One end of the fixing seat 131 abuts against the wall of the hole 1211, and the other end of the fixing seat 131 is slidably connected to the sliding member 133. The guide shaft 132 passes between the fixing seat 131 and the sliding member 133, and the axial direction of the guide shaft 132 is the same as the axial direction of the brush roller 12.

[0034] The sliding member 133 is slidable relative to the fixed base 131 in a first direction, so that the end of the sliding member 133 away from the fixed base 131 is engaged with the inner wall of the housing 11. The sliding member 133 is also slidable relative to the fixed base 131 in a second direction opposite to the first direction, so that the end of the sliding member 133 away from the fixed base 131 is separated from the inner wall of the housing 11. Both the first direction and the second direction coincide with the axial direction of the guide shaft 132.

[0035] The cleaning device 1 provided in this embodiment mainly includes a housing 11, a brush roller 12, and a fixing assembly 13. However, this does not mean that the cleaning device 1 can only include these two structures. The cleaning device 1 may include a flexible cleaning roller, a bracket, a filter element, a cleaning shovel, a garbage box, a motor, a clean water tank, a wastewater tank, a water pump, an air pump, etc.

[0036] The brush roller 12, fixing assembly 13, flexible cleaning roller, support, filter, cleaning shovel, waste box, motor, clean water tank, wastewater tank, water pump, and air pump are all housed within the casing 11. The support and cleaning shovel are located on opposite sides of the flexible cleaning roller. The cleaning shovel and brush roller 12 are located on the side of the flexible cleaning roller away from the support. The cleaning shovel is positioned between the flexible cleaning roller and the waste box. The brush roller 12 is further away from the surface to be cleaned than the cleaning shovel. The support surface facing the flexible cleaning roller has extrusion protrusions, which are used to extrude wastewater from the flexible cleaning roller.

[0037] The flexible cleaning roller is capable of absorbing liquid and is elastic. It is used to sweep away debris and remove dirt from the surface to be cleaned. A support frame is used to seal the flexible cleaning roller and to compress the wastewater. A filter element is used to filter impurities from the wastewater.

[0038] The outer periphery of the brush roller 12 is provided with cleaning bristles 122, and the brush roller 12 is used to sweep away debris from the self-cleaning roller. A cleaning shovel is used to collect and guide the movement of debris, and a debris box is used to store debris; debris removed by the self-cleaning shovel can be stored in the debris box. A motor is used to drive the rotation of the self-cleaning roller and also to drive the rotation of the brush roller 12.

[0039] The clean water tank stores clean water, and the wastewater tank stores wastewater. A water pump draws clean water from the clean water tank and outputs it to the flexible cleaning roller. An air pump evacuates the wastewater tank, creating a negative pressure environment that draws wastewater into it.

[0040] The support frame has a water flow channel for storing and guiding wastewater from the flexible cleaning roller. The housing 11 has a clean water pipe and a wastewater pipe. The clean water pipe connects the clean water tank to one end of the water flow channel, and the wastewater pipe connects the wastewater tank to the other end of the water flow channel. The clean water pipe is used to input clean water, and the wastewater pipe is used to discharge wastewater. When the flexible cleaning roller rotates, the clean water in the clean water tank flows to the flexible cleaning roller through the clean water pipe and the water flow channel. Meanwhile, the wastewater from the flexible cleaning roller is squeezed out by the extrusion protrusions on the support frame, and the wastewater flows to the wastewater tank through the water flow channel and the wastewater pipe, thereby cleaning the flexible cleaning roller.

[0041] Optionally, the cleaning device 1 further includes two seals respectively disposed at opposite ends of the bracket, the two seals being used to seal the water flow channel. A clean water pipe passes through one seal and connects to the water flow channel, while a wastewater pipe passes through the other seal and connects to the water flow channel.

[0042] This application also provides a sweeping and mopping robot 2, which includes a control component and a cleaning device 1. The control component is disposed on the cleaning device 1. The control component includes a controller and a sensor electrically connected to each other. The sensor is used to acquire sensing information and send the sensing information to the controller. The controller is used to receive the sensing information and control the cleaning device 1 to operate according to the sensing information.

[0043] The sweeper-mop combo 2 also includes a moving component, which is located on the cleaning device 1 and is used to move the cleaning device 1 and the control component. Optionally, the moving component includes multiple wheels that can rotate relative to the surface to be cleaned, thereby moving the sweeper-mop combo 2 and the control component.

[0044] When the sweeper and mop combo 2 is sweeping, the motor drives the flexible cleaning roller to rotate in the first cleaning direction, which in turn drives the brush roller 12 to rotate in the same direction. The rotation direction of the moving components is the same as the first cleaning direction. As the flexible cleaning roller sweeps away the debris placed on the surface to be cleaned, the cleaning blades collect and guide the debris, and the brush roller 12 sweeps the debris off the flexible cleaning roller into the debris box. Here, "debris" refers to unwanted or useless solid or liquid substances, which are waste generated by users in production, consumption, daily life, and other activities. Examples include used toilet paper, scattered vegetable roots, and fruit peels.

[0045] When the sweeper and mop combo 2 is mopping, the motor drives the flexible cleaning roller to rotate in a second cleaning direction. The rotating component rotates in the opposite direction to the second cleaning direction to remove dirt from the surface to be cleaned. The second cleaning direction is opposite to the first cleaning direction. Dirt refers to mud, oil stains, or other impurities that have soiled the surface to be cleaned; dirt can adhere to the surface of an object. Examples include dust and oil stains.

[0046] It should be noted that the working order of the various structural components of the sweeping and mopping machine 2 mentioned above is not important and should not be construed as a limitation of this application.

[0047] The inner wall of the housing 11 provided in this embodiment forms a receiving space 111. The brush roller 12, at least a portion of the flexible cleaning roller, at least a portion of the cleaning shovel, and the trash can are disposed within the receiving space 111.

[0048] The brush roller 12 provided in this embodiment includes a cylinder 121 and a plurality of cleaning bristles 122. The plurality of cleaning bristles 122 are disposed on the outer peripheral side of the cylinder 121, and the inner peripheral side of the cylinder 121 forms a hole 1211. The plurality of cleaning bristles 122 are used to sweep the debris on the flexible cleaning roller into the debris box. The motor is disposed on one side of the hole 1211 and is used to drive the brush roller 12 to rotate. The fixing assembly 13 is disposed on the other side of the hole 1211.

[0049] The fixing assembly 13 provided in this embodiment includes a fixing base 131, a guide shaft 132, and a sliding member 133. At least a portion of the fixing base 131 is disposed within the hole 1211, and the outer wall of the fixing base 131 can abut against the hole wall of the hole 1211, so that the fixing assembly 13 connects to the brush roller 12. Optionally, the fixing base 131 is detachably connected to the hole wall of the hole 1211. For example, the fixing base 131 can move into the hole 1211 along the axial direction of the brush roller 12, and can also be moved out of the hole 1211.

[0050] Optionally, the fixing seat 131 is engaged with the wall of the hole 1211. When the brush roller 12 rotates, the fixing seat 131 and the cylinder 121 rotate together relative to the guide shaft 132. Further optionally, the wall of the hole 1211 is provided with a mating protrusion, and the outer peripheral side of the fixing seat 131 is provided with a mating groove for accommodating at least part of the mating protrusion.

[0051] One end of the guide shaft 132 passes through the fixed base 131, and the other end passes through the sliding member 133. Optionally, the guide shaft 132 is fixedly connected to the fixed base 131, or the guide shaft 132 is detachably connected to the fixed base 131. For example, the connection between the guide shaft 132 and the fixed base 131 can be achieved through adhesive bonding, threaded connection, snap-fit, etc. Optionally, the guide shaft 132 is fixedly connected to the sliding member 133, or the guide shaft 132 is detachably connected to the sliding member 133. For example, the connection between the guide shaft 132 and the sliding member 133 can be achieved through adhesive bonding, threaded connection, snap-fit, etc. Optionally, the axial direction of the guide shaft 132 coincides with the axial direction of the brush roller 12.

[0052] The slider 133 is slidable relative to the fixed base 131 along the axial direction of the guide shaft 132. The slider 133 can slide in a first direction, gradually approaching the inner wall of the housing 11, thereby engaging with the inner wall of the housing 11. The slider 133 can also slide in a second direction, gradually moving away from the inner wall of the housing 11, thereby separating from the inner wall of the housing 11. For example, the first direction is left-handed and the second direction is right-handed; or, the first direction is right-handed and the second direction is left-handed. The first direction is as follows: Figure 4 As shown in D1, the second direction is as follows Figure 4 As shown in D2.

[0053] Optionally, the motor is rotatably connected to the inner wall of the housing 11, and the motor can swing relative to the inner wall of the housing 11. When it is necessary to install the brush roller 12 onto the housing 11, the motor is first tilted relative to the inner wall of the housing 11, then the brush roller 12 is fitted onto the motor, and then the motor is returned to its original position, so that the motor swings to be perpendicular to the inner wall of the housing 11. Furthermore, using the fixing component 13 provided on the brush roller 12, the sliding member 133 is slid along the first direction, so that the sliding member 133 contacts and engages with the inner wall of the housing 11, thereby fixing the brush roller 12 inside the housing 11.

[0054] Optionally, when it is necessary to remove the brush roller 12 from the housing 11, the slider 133 is first slid along the second direction to separate the slider 133 from the inner wall of the housing 11. Then, the motor is tilted relative to the inner wall of the housing 11, and the brush roller 12 is removed from the motor to remove the brush roller 12 from the housing 11.

[0055] In summary, the cleaning device 1 provided in this embodiment, by setting the fixing component 13, allows the sliding member 133 to slide relative to the fixing seat 131 in the axial direction of the guide shaft 132. Specifically, when it is necessary to install the brush roller 12, the sliding member 133 is slid along the first direction, so that the sliding member 133 contacts and engages with the inner wall of the housing 11 to fix the brush roller 12 inside the housing 11; when it is necessary to disassemble the brush roller 12, the sliding member 133 is slid along the second direction, so that the sliding member 133 separates from the inner wall of the housing 11 to remove the brush roller 12 from the housing 11.

[0056] Therefore, by setting the fixing component 13, this embodiment reduces the difficulty of disassembling and installing the brush roller 12, making it easier for users to disassemble and install the brush roller 12 and to clean and maintain it.

[0057] Please refer to this as well. Figures 1-7 In one embodiment, the other end of the fixed base 131 is provided with a sliding space 1311, and part of the sliding member 133 and part of the guide shaft 132 are disposed in the sliding space 1311; the inner bottom wall of the sliding space 1311 is provided with a first connecting hole 1312, the end of the sliding member 133 facing the fixed base 131 is provided with a second connecting hole 1331, one end of the guide shaft 132 is disposed in the first connecting hole 1312, and the other end of the guide shaft 132 is disposed in the second connecting hole 1331.

[0058] The sliding space 1311 is provided on the side of the fixed base 131 facing the slider 133. The sliding space 1311 can be a groove or a hole. Part of the slider 133 is provided in the sliding space 1311. It can also be understood that the other end of the fixed base 131 is sleeved on the slider 133, and the slider 133 can slide in the sliding space 1311.

[0059] The sliding space 1311 has a first connecting hole 1312 on its inner bottom wall facing the slider 133. The first connecting hole 1312 is used to accommodate one end of the guide shaft 132. Optionally, one end of the guide shaft 132 abuts against the wall of the first connecting hole 1312, or there is a gap between one end of the guide shaft 132 and the wall of the first connecting hole 1312. Optionally, the guide shaft 132 is fixedly connected to the wall of the first connecting hole 1312, or the guide shaft 132 is detachably connected to the wall of the first connecting hole 1312. For example, the connection method between the guide shaft 132 and the wall of the first connecting hole 1312 can be adhesive connection, threaded connection, snap-fit, etc.

[0060] The end of the slider 133 facing the sliding space 1311 is provided with a second connecting hole 1331. The second connecting hole 1331 is used to accommodate the other end of the guide shaft 132. Optionally, the other end of the guide shaft 132 abuts against the wall of the second connecting hole 1331, or there is a gap between the other end of the guide shaft 132 and the wall of the second connecting hole 1331. Optionally, the guide shaft 132 is fixedly connected to the wall of the second connecting hole 1331, or the guide shaft 132 is detachably connected to the wall of the second connecting hole 1331. For example, the connection method between the guide shaft 132 and the wall of the second connecting hole 1331 is adhesive connection, threaded connection, snap-fit, etc.

[0061] In summary, this embodiment provides a sliding space 1311 on the fixed base 131 to allow the sliding member 133 to slide within the sliding space 1311, thereby achieving engagement and disengagement with the inner wall of the housing 11. Furthermore, by providing a first connecting hole 1312 and a second connecting hole 1331 to facilitate the positioning and limiting of the guide shaft 132, the installation difficulty of the guide shaft 132 is reduced, and the connection performance between the guide shaft 132, the fixed base 131, and the sliding member 133 is improved, thereby enhancing the reliability of the fixing assembly 13.

[0062] Please refer to this as well. Figures 1-7 In one embodiment, the inner sidewall of the sliding space 1311 is provided with a limiting part 1313, and the outer peripheral sidewall of the sliding member 133 located in the sliding space 1311 is provided with a protruding ring 1332, and the limiting part 1313 is used to abut against the protruding ring 1332.

[0063] A limiting part 1313 protrudes from the inner wall of the sliding space 1311, and there is a gap between the limiting part 1313 and the inner bottom wall of the sliding space 1311, allowing the sliding member 133 to slide back and forth between the limiting part 1313 and the inner bottom wall of the sliding space 1311. A protruding ring 1332 is provided on the outer peripheral side wall of the sliding member 133, and the protruding ring 1332 is arranged around the sliding member 133 in the circumferential direction. As the sliding member 133 slides, the protruding ring 1332 can slide back and forth between the limiting part 1313 and the inner bottom wall of the sliding space 1311. When the limiting part 1313 abuts against the protruding ring 1332, the sliding member 133 cannot move relative to the fixed base 131.

[0064] Optionally, the sliding space 1311 is further provided with a through hole, which penetrates the outer peripheral sidewall of the fixing seat 131 and the inner sidewall of the sliding space 1311. Further optionally, the through hole is disposed adjacent to the limiting part 1313.

[0065] In summary, this embodiment provides a limiting part 1313 in the sliding space 1311, which cooperates with the protruding ring 1332 on the sliding member 133 to limit the sliding range of the sliding member 133 relative to the fixed seat 131, thereby preventing the sliding member 133 from falling off the fixed seat 131 and improving the reliability of the fixing component 13.

[0066] Please refer to this as well. Figures 1-7 In one embodiment, the fixing component 13 further includes an elastic element 134, which is sleeved on the guide shaft 132. One end of the elastic element 134 abuts against the fixing seat 131, and the other end of the elastic element 134 abuts against the sliding element 133.

[0067] Optionally, the elastic element 134 can be a spring, torsion spring, leaf spring, silicone element, or other elastic structural component. Optionally, the elastic element 134 is directly connected to the fixed base 131, or indirectly connected to the fixed base 131 through other components. Optionally, the elastic element 134 is directly connected to the sliding element 133, or indirectly connected to the sliding element 133 through other components. Optionally, the connection method between the elastic element 134 and the fixed base 131 can be overlapping, adhesive, threaded, snap-fit, etc. Optionally, the connection method between the elastic element 134 and the sliding element 133 can be overlapping, adhesive, threaded, snap-fit, etc.

[0068] When the slider 133 slides along the second direction to separate from the inner wall of the housing 11, the elastic member 134 is in a compressed state. The compressed elastic member 134 has a rebound force, enabling the slider 133 to slide along the first direction, thereby fixing the slider 133 to the inner wall of the housing 11. Therefore, when the slider 133 separates from the inner wall of the housing 11, the elastic member 134 is in a compressed state; and when the slider 133 is engaged with the inner wall of the housing 11, the elastic member 134 is in a compressed state or a balanced state, which is not limited in this embodiment.

[0069] In summary, this embodiment improves the reliability of the fixing assembly 13 by providing an elastic element 134 and utilizing the rebound force of the elastic element 134 to fix the sliding element 133 to the inner wall of the housing 11.

[0070] Please refer to this as well. Figures 1-7 In one embodiment, one end of the elastic member 134 is disposed in the first connecting hole 1312, and the hole wall of the first connecting hole 1312 is provided with a first stepped surface 1314, which is used to abut one end of the elastic member 134.

[0071] A portion of the elastic element 134 is disposed within the first connecting hole 1312, and the first connecting hole 1312 is provided with a first stepped surface 1314, which can limit the deformation of the elastic element 134. Optionally, the connection method between the elastic element 134 and the first stepped surface 1314 is lap joint, adhesive connection, threaded connection, snap-fit, etc.

[0072] Therefore, by providing a first stepped surface 1314 in the first connecting hole 1312 to facilitate the positioning and limiting of the elastic member 134, this embodiment not only reduces the installation difficulty of the elastic member 134, but also improves the connection performance between the elastic member 134 and the fixed seat 131, thereby improving the reliability of the fixing assembly 13.

[0073] Please refer to this as well. Figures 1-7 In one embodiment, the fixing component 13 further includes a bushing 135, which is sleeved on the guide shaft 132, and the other end of the elastic member 134 abuts against the bushing 135; the bushing 135 is disposed in the second connecting hole 1331, and the hole wall of the second connecting hole 1331 is provided with a second stepped surface 1333, which is used to abut against the bushing 135.

[0074] The elastic element 134 is indirectly connected to the sliding element 133 through the connecting bushing 135. The bushing 135 is sleeved on the guide shaft 132 and is located in the second connecting hole 1331. Therefore, by setting the bushing 135, this embodiment can reduce the friction between the guide shaft 132 and the sliding element 133, improve the reliability of the fixing assembly 13, and also make the rebound force of the elastic element 134 evenly distributed on the sliding element 133, avoid the problem of local rebound force concentration, and extend the service life of the fixing assembly 13.
