Since the second cleaning assembly contacts the surface to be cleaned only when necessary, the cleaning seat body can clean stubborn stains without scratching the surface to be cleaned.

Description

Technical Field

[0001] This application belongs to the field of household appliance technology, and in particular relates to a cleaning seat, cleaning equipment and cleaning system. Background Technology

[0002] Floor scrubbers, which combine dust removal, mopping, and cleaning functions, offer significantly improved cleaning efficiency and are highly practical, leading to their widespread use. However, stubborn stains occasionally accumulate on household floors, and floor scrubbers often struggle to effectively remove these stains, resulting in low cleaning efficiency and requiring manual cleaning by the user in most cases. Utility Model Content

[0003] The purpose of this application is to provide a cleaning seat, cleaning equipment, and cleaning system to solve the technical problem that existing floor scrubbers are not effective at cleaning stubborn stains on the ground.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] The first aspect of this application provides a cleaning seat, comprising:

[0006] Support frame;

[0007] The first cleaning unit includes a first cleaning component connected to the support frame;

[0008] The second cleaning unit includes a second cleaning component and a lifting structure. The second cleaning component has a greater cleaning capacity than the first cleaning component. The lifting structure is supported on a support frame, and the second cleaning component is connected to the lifting structure.

[0009] When the lifting structure moves the second cleaning component to the first position, the second cleaning component is housed in the receiving slot on the support frame. When the lifting structure moves the second cleaning component to the second position, the second cleaning component is located in front of the first cleaning component along the travel direction of the cleaning seat, so that the second cleaning component can contact the surface to be cleaned.

[0010] In some implementations, the lifting structure includes a first drive device and a connecting arm. The first drive device is supported on a support frame, and the two ends of the connecting arm are respectively connected to the first drive device and the second cleaning component. The first drive device can drive the second cleaning component to swing through the connecting arm.

[0011] In some implementations, at least one of the opposite sides of the support frame is connected to a connecting arm along the travel direction perpendicular to the cleaning seat, and a second cleaning component is provided on each connecting arm.

[0012] In some implementations, each connecting arm is connected to a corresponding first drive device. The first drive device and the second cleaning component connected to the connecting arm are located on the side of the connecting arm facing the cleaning seat, and the first drive device is located between the first cleaning component and the receiving groove along the travel direction of the cleaning seat.

[0013] In some implementations, the receiving groove is connected to the top surface of the support frame and to the side of the support frame on which the connecting arm is located. The receiving groove includes a first groove wall and a second groove wall. The first groove wall and the second groove wall are arranged opposite to each other along the traveling direction of the cleaning seat and the first groove wall and the second groove wall are arc-shaped.

[0014] In some implementations, the second cleaning component includes a second driving device and a second cleaning element. The second driving device is connected to the lifting structure, and the second cleaning element is connected to the second driving device. The second driving device can drive the second cleaning element to rotate or move.

[0015] In some implementations, a second cleaning element is formed within a receiving cavity and a mounting hole, the receiving cavity being connected to the mounting hole, the receiving cavity being open to the end face of the second cleaning element that is attached to one end of the lifting structure, and a second driving device being located in the receiving cavity with the shaft of the second driving device inserted into the mounting hole.

[0016] In some implementations, the circumferential outer surface of the second cleaning element is provided with a number of bristles.

[0017] In some implementations, the cleaning seat also includes a controller electrically connected to the lifting structure; when the controller receives a signal for powerful cleaning, the controller can control the lifting structure to move the second cleaning component toward a second position that contacts the surface to be cleaned.

[0018] In some implementations, the cleaning seat also includes a detection device for detecting the current of the first drive device in the lifting structure. The detection device is connected to a controller. When the first drive device is activated, the controller can respond to the current increase signal transmitted by the detection device to control the first drive device to stop operating.

[0019] In some implementations, the second cleaning component is electrically connected to the controller, which can control the operation of the second drive mechanism of the second cleaning component in response to the second cleaning component being in a second position.

[0020] A second aspect of this application provides a cleaning device, including an upright part and a cleaning seat as provided in any of the above technical solutions, wherein the cleaning seat is connected to the upright part.

[0021] A third aspect of this application provides a cleaning system, including a pile and cleaning equipment as provided in any of the above technical solutions, wherein the pile is configured to support the cleaning equipment.

[0022] The beneficial effects of this application are as follows: The cleaning seat provided in this embodiment includes a first cleaning unit and a second cleaning unit, and the second cleaning unit includes a second cleaning component and a lifting structure. When it is necessary to clean stubborn stains on the surface to be cleaned, the lifting structure drives the second cleaning component to a second position in contact with the ground, so that the second cleaning component can clean the stubborn stains on the floor. When the second cleaning component is not needed, the lifting structure drives the second cleaning component to a first position separated from the ground, at which time the surface to be cleaned can be cleaned by the first cleaning unit. Since the second cleaning component only contacts the surface to be cleaned when needed, the cleaning seat can clean stubborn stains without causing scratches or other damage to the surface to be cleaned by the second cleaning component.

[0023] In addition, when the second cleaning component comes into contact with the surface to be cleaned, the second cleaning component is located in front of the first cleaning component, so as not to increase the length of the cleaning seat in the left and right direction. This allows the cleaning seat to pass through narrow floors. When the second cleaning component has finished removing stubborn stains from the surface to be cleaned, the cleaning seat can continue to move forward so that the first cleaning component can clean the original stubborn stains on the surface again, improving the degree of floor cleaning. When the second cleaning component is stored in the receiving slot of the support frame, it does not affect the cleaning of the floor by the first cleaning component, making the structure of the cleaning seat compact.

[0047] Figure 1 Schematic diagram of the structure of the cleaning seat 100 provided in the embodiments of this application Figure 1 , Figure 2 Schematic diagram of the structure of the cleaning seat 100 provided in the embodiments of this application Figure 2 Before describing the cleaning seat 100 provided in this embodiment, the following orientation is defined: the cleaning seat 100 can be calibrated using the following three mutually perpendicular axes: the X-axis, the Y-axis, and the Z-axis. For details, please refer to... Figures 1-2 The Z-axis is along the height of the cleaning seat 100, the Y-axis is the front-to-back direction of the cleaning seat 100, and the X-axis is the left-to-right direction of the cleaning seat 100.

[0048] The cleaning seat 100 provided in this embodiment includes a support frame 10, a first cleaning unit, and a second cleaning unit.

[0049] Please see Figure 1 and Figure 2 The image illustrates the appearance of the cleaning seat 100. In one example, the cleaning seat 100 can be applied to a handheld cleaning device, such as a handheld floor scrubber, to clean the surface to be cleaned as the cleaning seat 100 moves across the floor.

[0050] In this embodiment, the first cleaning unit includes a first cleaning component 20 rotatably connected to the support frame 10. (See also...) Figure 1 and Figure 2 This illustrates that the first cleaning component 20 is supported on the support frame 10. In one example, the two ends of the first cleaning component 20 along its length direction are... Figure 1 Both ends of the first cleaning component 20 are rotatably connected to the support frame 10 in the X-axis direction. When the first cleaning component 20 rotates, it can clean the surface to be cleaned, such as the ground.

[0051] In one example, the first cleaning unit further includes a drive device connected to the first cleaning component 20. The drive device is supported on the support frame 10 and is used to drive the first cleaning component 20 to rotate so that when the cleaning seat 100 moves on the surface to be cleaned, the drive device drives the first cleaning component 20 to rotate to clean the surface to be cleaned.

[0052] In one example, the first cleaning component 20 rotates only relative to the support frame 10 along its own axis; the first cleaning component 20 cannot be adjusted in the height direction relative to the support frame 10, i.e., along... Figure 1 The first cleaning component 20 in the Z-axis direction cannot be adjusted in position.

[0053] In one example, the first cleaning component 20 includes a support roller and a first cleaning element disposed on the support roller. The support roller is rotatably supported on the support frame 10, and the first cleaning element is used to contact and clean the surface to be cleaned. Since the first cleaning component 20 is always in contact with the surface to be cleaned, if the material of the first cleaning element is hard, it may scratch the floor due to prolonged contact. Therefore, to protect the floor from scratches, the material of the first cleaning element is usually soft. Here, "soft material" refers to a material that makes it difficult for the cleaning seat 100 to scratch the floor during long-term use. For example, in a specific example, the material of the first cleaning element can be soft bristles, a cloth, or silicone, etc.

[0054] To protect the floor, the first cleaning element on the first cleaning assembly 20 is made of a soft material. However, stubborn stains may occasionally appear on the floor in the home. When cleaning stubborn stains with the first cleaning assembly 20, the cleaning effect is often poor and the cleaning efficiency is low. In most cases, users need to manually clean the stubborn stains.

[0055] Therefore, the cleaning seat 100 provided in this embodiment also includes a second cleaning unit. The second cleaning unit has a greater cleaning capacity than the first cleaning unit, and can be used to clean stubborn stains on the surface to be cleaned. Specifically, please refer to... Figure 1 and Figure 2The second cleaning unit includes a second cleaning component 30 and a lifting structure 40. The lifting structure 40 is supported on the support frame 10. The second cleaning component 30 is connected to the lifting structure 40. When the lifting structure 40 moves, it can change the position between the second cleaning component 30 and the surface to be cleaned. The cleaning capacity of the second cleaning component 30 is greater than that of the first cleaning component 20. When the lifting structure 40 moves the second cleaning component 30 to a position where the second cleaning component 30 contacts the surface to be cleaned, the second cleaning component 30 can clean stubborn stains on the surface.

[0056] In one example, the number of second cleaning units is one, or the number of second cleaning units is two or more.

[0057] In this embodiment, the cleaning capacity of the second cleaning component 30 is greater than that of the first cleaning component 20. For example, in one implementation scenario, the second cleaning component 30 includes a second cleaning element 32 for contacting and cleaning the ground. The second cleaning element 32 is made of a hard material to clean stubborn stains on the surface to be cleaned. Regarding the hard material, it can be understood that the hardness of the material of the second cleaning element 32 on the second cleaning component 30 is greater than the hardness of the material of the first cleaning element on the first cleaning component 20. Since the second cleaning element 32 is made of a hard material, to avoid damage to the floor due to prolonged contact between the second cleaning element 32 and the floor, a lifting structure 40 is used to connect the second cleaning component 30 and the support frame 10. When the second cleaning component 30 is not needed, it can be moved to a position separated from the ground by the lifting structure 40.

[0058] Regarding the fact that the second cleaning component 30 has a greater cleaning capacity than the first cleaning component 20, for example, in another implementation scenario, when the material of the second cleaning element 32 is the same as the material of the first cleaning element on the first cleaning component 20, the second cleaning component 30 can be moved to a state of compression with the ground by the lifting structure 40, and the cleaning of stubborn stains on the ground can be achieved when the cleaning seat 100 moves. That is, by increasing the friction between the second cleaning component 30 and the floor, the cleaning capacity of the second cleaning component 30 is improved.

[0059] Of course, to make the second cleaning component 30 have a greater cleaning capacity than the first cleaning component 20, the material hardness of the second cleaning element 32 on the second cleaning component 30 is greater than that of the first cleaning element on the first cleaning component 20. At the same time, the friction between the second cleaning component 30 and the floor is also increased to improve the cleaning capacity of the second cleaning component 30, thus making the cleaning capacity of the second cleaning component 30 greater than that of the first cleaning component 20.

[0060] In this embodiment, when the second cleaning component 30 is not required to clean the surface to be cleaned, the lifting structure 40 can move the second cleaning component 30 to the first position. At this time, the second cleaning component 30 is housed in the receiving groove 11 on the support frame 10. Please refer to [link to relevant documentation]. Figure 1 This illustrates that the second cleaning component 30 is housed in the receiving slot 11 on the support frame 10; when the second cleaning component 30 needs to clean the surface to be cleaned, the lifting structure 40 can move the second cleaning component 30 to the second position. At this time, along the traveling direction of the cleaning seat 100, Figure 2 The second cleaning component 30 is located in front of the first cleaning component 20 in the direction indicated by the arrow on the Y-axis. When the second cleaning component 30 is activated, it can clean the surface to be cleaned.

[0061] In this embodiment, when the second cleaning component 30 contacts the surface to be cleaned, the second cleaning component 30 is located in front of the cleaning base 100, so that the cleaning base 100 is not increased in the left and right directions. Figure 2 The length along the X-axis allows the cleaning seat 100 to pass through narrow surfaces; when the second cleaning component 30 has finished removing stubborn stains from the surface to be cleaned, the cleaning seat 100 can continue to move forward so that the first cleaning component 20 can clean the original stubborn stains on the surface again, thus improving the degree of cleaning of the surface.

[0062] In this embodiment, when the second cleaning component 30 is housed in the receiving slot 11 of the support frame 10, it does not affect the first cleaning component 20 from cleaning the floor, making the structure of the cleaning seat 100 compact.

[0063] The cleaning seat 100 provided in this embodiment includes a first cleaning unit and a second cleaning unit. The second cleaning unit includes a second cleaning component 30 and a lifting structure 40. When it is necessary to clean stubborn stains on the surface to be cleaned, the lifting structure 40 drives the second cleaning component 30 to a second position in contact with the ground, so that the second cleaning component 30 can clean the stubborn stains on the surface to be cleaned. When the second cleaning component 30 is not needed, the lifting structure 40 drives the second cleaning component 30 to a first position separated from the ground, at which time the surface to be cleaned can be cleaned by the first cleaning unit. Since the second cleaning component 30 only contacts the surface to be cleaned when needed, the cleaning seat 100 can clean stubborn stains without causing scratches or other damage to the surface to be cleaned by the second cleaning component 30.

[0064] In one embodiment, the cleaning seat 100 further includes a controller electrically connected to the lifting structure 40; when the controller receives a signal for strong cleaning, the controller can control the lifting structure 40 to move the second cleaning component 30 toward a second position that contacts the surface to be cleaned.

[0065] It is worth noting that the controller can be located inside or outside the cleaning seat 100. For example, when the cleaning seat 100 is used on a handheld floor scrubber, the cleaning seat 100 is connected to the upright part of the handheld floor scrubber, and the controller can be located inside the upright part of the handheld floor scrubber.

[0066] When the second cleaning component 30 is in the first position, if the controller receives a strong cleaning signal, the controller can control the lifting structure 40 to move the second cleaning component 30 towards the second position where it contacts the surface to be cleaned. The strong cleaning signal can be generated by the identification device on the cleaning seat 100 detecting stubborn stains on the surface to be cleaned and sending a signal to the controller, which then recognizes the received signal as a strong cleaning signal; or, it can be generated by the user observing stubborn stains on the surface to be cleaned and sending a strong cleaning command to the cleaning seat 100, which the controller then recognizes as a strong cleaning signal.

[0067] In one example, a first operation button is provided on the upright part of the handheld floor scrubber. When the user presses the first operation button, they can send a powerful cleaning command to the cleaning seat 100. It is worth noting that the first operation button can be a mechanical button or a touch button formed on the display screen.

[0068] In one example, a recognition device is provided on the cleaning seat 100. The recognition device includes an image acquisition device and a processor. The image acquisition device is connected to the processor by a signal. The image acquisition device is used to acquire the condition of the surface to be cleaned to form image information. The image acquisition device sends the acquired image information to the processor. The processor determines whether there are stubborn stains. If there are, the processor sends a signal to the controller. The controller recognizes the received signal as a signal for powerful cleaning.

[0069] It is worth noting that the processor of the identification device and the controller of the cleaning base 100 can be integrated into the configuration.

[0070] In one example, the image acquisition device sends the acquired image information to the processor. When the processor determines that there is a lot of garbage on the surface to be cleaned, it can also send a signal to the controller. The controller recognizes the received signal as a signal for powerful cleaning.

[0071] In one example, a waste detection device is installed on the waste collection channel of the cleaning seat 100 or the waste collection channel of the upright part. When the waste detection device detects that there is a lot of waste in the waste collection channel, it can send a signal to the controller. The controller will recognize the received signal as a signal for strong cleaning.

[0072] The above describes how, when the controller receives a signal for powerful cleaning, it can control the lifting structure 40 to move the second cleaning component 30 towards a second position that contacts the surface to be cleaned. It is worth noting that, when the controller receives a signal that stubborn stains have been removed, it can control the lifting structure 40 to move the second cleaning component 30 towards a first position.

[0073] In one example, a second operation button is provided on the upright part of the handheld floor scrubber. When the user presses the second operation button, they can send a command to the cleaning seat 100 that stubborn stains have been removed. It is worth noting that the second operation button can be a mechanical button or a touch button formed on the display screen.

[0074] In one example, the image acquisition device sends the acquired image information to the processor, which determines whether the stubborn stains have been removed. If so, the processor sends a signal to the controller, which recognizes the received signal as a signal that the stubborn stains have been removed.

[0075] Please see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the second cleaning unit provided in an embodiment of this application. Figure 4 An exploded view of the cleaning seat 100 provided in an embodiment of this application.

[0076] In one embodiment, please refer to Figure 3 The lifting structure 40 includes a first driving device 41 and a connecting arm 42. The first driving device 41 is supported on the support frame 10. The two ends of the connecting arm 42 are respectively connected to the first driving device 41 and the second cleaning component 30. The first driving device 41 can drive the second cleaning component 30 to swing through the connecting arm 42.

[0077] In one example, the first driving device 41 is a drive motor, and the first driving device 41 is directly connected to the connecting arm 42; or, in other examples, the first driving device 41 is a drive motor, and the first driving device 41 is indirectly connected to the connecting arm 42, for example, the first driving device 41 is connected to the connecting arm 42 through a transmission mechanism such as a gear transmission structure.

[0078] When the first drive device 41 is a drive motor and the first drive device 41 is directly connected to the connecting arm 42, when the second cleaning component 30 is in the first position, the first drive device 41 is started. The first drive device 41 drives the connecting arm 42 to rotate around the axis of the output shaft of the first drive device 41 until the first drive device 41 drives the connecting arm 42 to move to the second position, and then controls the second drive device 31 to stop.

[0079] In one example, see Figure 1 The first driving device 41 is located inside the support frame 10; or, in other examples, the first driving device 41 is disposed on the top surface of the support frame 10. In this case, the lifting structure 40 can also be provided, including a housing, with the first driving device 41 disposed inside the housing, and the housing disposed on the top surface of the support frame 10 and connected to the support frame 10.

[0080] In one example, see Figure 1 The connecting arm 42 is located on the cleaning seat 100 along the left and right direction. Figure 1 On one side in the X-axis direction; or, in other examples, the connecting arm 42 can be positioned above the support frame 10.

[0081] In one example, the connecting arm 42 is a plate-like structure to simplify its structure; or, in other examples, please refer to [link to relevant documentation]. Figure 3 The connecting arm 42 includes a first housing 421 and a second housing 422. The first housing 421 and the second housing 422 are arranged opposite to each other along the thickness direction of the connecting arm 42. The first housing 421 and the second housing 422 are connected and a cavity is formed inside both of them to reduce the weight of the connecting arm 42.

[0082] In one example, see Figure 3 The two ends of the connecting arm 42 along the length direction are semi-circular to avoid the situation where the two ends of the connecting arm 42 along the length direction are right angles, which could easily scratch the user.

[0083] In this embodiment of the application, by setting the lifting structure 40 to include a first driving device 41 and a connecting arm 42, the lifting structure 40 is simple in structure and stable in operation.

[0084] It is worth noting that the above embodiment describes the lifting structure 40 as including a first driving device 41 and a connecting arm 42, and the first driving device 41 can drive the second cleaning component 30 to swing through the connecting arm 42. In other embodiments, the lifting structure 40 can be a robotic arm structure, and the movement trajectory of the second cleaning component 30 driven by the lifting structure 40 is not limited to swinging. For example, when the second cleaning component 30 is in the first position, the lifting structure 40 can drive the second cleaning component 30 to move upward, then drive the second cleaning component 30 to move horizontally forward, and then drive the second cleaning component 30 to move downward to the second position where it contacts the surface to be cleaned.

[0085] In one embodiment, along the direction of travel perpendicular to the cleaning seat 100 (i.e., along...) Figure 1 At least one of the two opposite sides of the support frame 10 (in the X-axis direction) is connected to a connecting arm 42, and a second cleaning component 30 is provided on each connecting arm 42.

[0086] In this embodiment, a connecting arm 42 can be provided on one of the left or right sides of the support frame 10, or a connecting arm 42 can be provided on each of the left and right sides of the support frame 10, with a second cleaning component 30 provided on each connecting arm 42. Please refer to [link to relevant documentation]. Figure 1 This illustrates that a connecting arm 42 is installed on one of the left or right sides of the support frame 10.

[0087] In one example, a connecting arm 42 is provided on each of the left and right sides of the support frame 10, and both connecting arms 42 are connected to the same first driving device 41. For example, the two connecting arms 42 are connected to the same first driving device 41 through a transmission mechanism. Alternatively, in other examples, a connecting arm 42 is provided on each of the left and right sides of the support frame 10, and the two connecting arms 42 are respectively connected to the corresponding first driving device 41. That is, the number of first driving devices 41 is the same as the number of connecting arms 42, and the two correspond one-to-one.

[0088] In one example, see Figure 1 The length of the second cleaning component 30 along the axial direction is not greater than the length of the first cleaning component 20 along the axial direction. For example, the length of the first cleaning component 20 along the axial direction is 1 to 6 times the length of the second cleaning component 30 along the axial direction.

[0089] In this embodiment, by setting the connecting arm 42 on the side perpendicular to the travel direction of the cleaning seat 100, the first driving device 41 and the second cleaning component 30 can be conveniently set on the connecting arm 42, which is beneficial to the overall aesthetics of the cleaning seat 100.

[0090] In one embodiment, each connecting arm 42 is connected to a corresponding first driving device 41. The first driving device 41 and the second cleaning assembly 30 connected to the connecting arm 42 are located on the side of the connecting arm 42 facing the cleaning seat 100. The first driving device 41 is located inside the support frame 10 and along the travel direction of the cleaning seat 100 (i.e., Figure 1 (In the X-axis direction) The first drive device 41 is located between the first cleaning component 20 and the receiving tank 11.

[0091] In one example, the two ends of the connecting arm 42 along its length are a first end and a second end, respectively. The first driving device 41 is close to the first end of the connecting arm, and the second cleaning component 30 is close to the second end of the connecting arm. Both the first end and the second end of the connecting arm are semi-circular, and the radius of the second end of the connecting arm is larger than the radius of the first end of the connecting arm, so as to facilitate the installation of the second cleaning component 30 on the connecting arm 42 while minimizing the width dimension of the connecting arm 42.

[0092] In one example, see Figure 4The first drive device 41 is close to the first cleaning component 20. For example, the distance between the first drive device 41 and the first cleaning component 20 is in the range of 10mm to 50mm.

[0093] In one example, the cross-section of the output shaft of the first drive device 41 is polygonal, a limiting step is formed on the output shaft, and a mounting member 43 is installed at the free end of the output shaft, such as a nut. The output shaft of the first drive device 41 passes through the connecting arm 42 along the thickness direction, and the two opposite sides of the connecting arm 42 along the thickness direction are limited between the limiting step and the mounting member 43.

[0094] In this embodiment of the application, by setting the first driving device 41 and the second cleaning component 30 on the side of the connecting arm 42 facing the cleaning seat 100, and the first driving device 41 being located between the first cleaning component 20 and the receiving groove 11, the overall structure of the cleaning seat 100 can be made compact.

[0095] In one embodiment, please refer to Figure 4 The receiving groove 11 is connected to the top surface of the support frame 10 and the side of the support frame 10 on the side where the connecting arm 42 is provided. The receiving groove 11 includes a first groove wall 111 and a second groove wall 112. The first groove wall 111 and the second groove wall 112 are arranged opposite to each other along the traveling direction of the cleaning seat 100 and the first groove wall 111 and the second groove wall 112 are arc-shaped.

[0096] It is worth noting that, in the embodiments of this application, the arc shape of the first groove wall 111 and the second groove wall 112 refers to the overall outline shape of the first groove wall 111 and the second groove wall 112, and is not limited to just a smooth arc surface. For example, reinforcing ribs can be formed on the first groove wall 111 and / or the second groove wall 112.

[0097] Please see Figure 4 The receiving tank 11 also includes a third tank wall 113 and a fourth tank wall 114. The fourth tank wall 114 connects the first tank wall 111, the second tank wall 112 and the third tank wall 113, and the fourth tank wall 114 is the bottom surface of the receiving tank 11. When the second cleaning component 30 is in the first position, the second cleaning component 30 is in contact with the fourth tank wall 114.

[0098] It is worth noting that the contact between the second cleaning component 30 and the fourth tank wall 114 can be either a situation where there is no pressure between them, or a situation where there is pressure between them.

[0099] In one example, the length of the second cleaning component 30 along the height direction is not greater than the depth of the receiving groove 11; or, in other examples, the length of the second cleaning component 30 along the height direction is slightly greater than the depth of the receiving groove 11, for example, the difference between the length of the second cleaning component 30 along the height direction and the depth of the receiving groove 11 is in the range of 1 to 10 mm.

[0100] In one example, when the second cleaning component 30 is in the first position, there is a gap between the third tank wall 113 and the second cleaning component 30. For example, the gap between the third tank wall 113 and the second cleaning component 30 is in the range of 1 to 10 mm.

[0101] In this embodiment, the first groove wall 111 and the second groove wall 112 are set to be arc-shaped to match the movement trajectory of the second cleaning component 30. That is, while enabling the second cleaning component 30 to move to the receiving groove 11, the volume of the receiving groove 11 can be minimized to improve the aesthetics of the cleaning seat 100.

[0102] Please see Figures 5-6 , Figure 5 This is a cross-sectional schematic diagram of the second cleaning unit provided in an embodiment of this application. Figure 6 This is a schematic diagram of the structure of the connecting arm 42 and the second driving device 31 provided in the embodiments of this application.

[0103] In one embodiment, please refer to Figure 5 The second cleaning component 30 includes a second driving device 31 and a second cleaning element 32. The second driving device 31 is connected to the lifting structure 40, and the second cleaning element 32 is connected to the second driving device 31. The second driving device 31 can drive the second cleaning element 32 to rotate or move.

[0104] In one example, the second drive device 31 is a drive motor, which can drive the second cleaning element 32 to rotate so that the second cleaning element 32 cleans the surface to be cleaned; or, in other examples, the second drive device 31 is a linear drive device, such as a cylinder, which can drive the second cleaning element 32 to move back and forth in a straight line so that the second cleaning element 32 cleans the surface to be cleaned.

[0105] In one example, see Figure 5 The second cleaning element 32 has a plurality of bristles 3221 on its circumferential outer side; in other examples, the second cleaning element 32 includes a cloth, which may be made of fiber cloth or linen.

[0106] In this embodiment of the application, by setting the second cleaning component 30 to include a second driving device 31 and a second cleaning element 32, the second cleaning component 30 can clean stubborn stains on the surface to be cleaned, while the structure of the second cleaning component 30 is simple.

[0107] It is worth noting that the above embodiments describe the second cleaning component 30 as including the second driving device 31 and the second cleaning element 32. In other embodiments, the second cleaning component 30 may not include the second driving device 31. The second cleaning component 30 is pressed tightly onto the surface to be cleaned by the lifting structure 40, and the cleaning seat 100 moves back and forth on the surface to be cleaned to achieve the cleaning of the second cleaning component 30.

[0108] In one embodiment, please refer to Figure 5 The second cleaning element 32 is formed in the receiving cavity 3211 and the mounting hole 3212. The receiving cavity 3211 is connected to the mounting hole 3212. The receiving cavity 3211 is opened to the end face of the second cleaning element 32 that is attached to one end of the lifting structure 40. The second driving device 31 is located in the receiving cavity 3211 and the shaft of the second driving device 31 is inserted into the mounting hole 3212.

[0109] In one example, see Figure 5 and Figure 6 The connecting arm 42 includes a first housing 421 and a second housing 422. The first housing 421 is located near the support frame 10. (See attached image) Figure 5 and Figure 6 A cylindrical portion 423 is formed on the side of the first housing 421 opposite to the second housing 422. The cylindrical portion 423 is inserted into the receiving cavity 3211 of the second cleaning element 32 and is fixedly connected to the second cleaning element 32. The second driving device 31 is located inside the cylindrical portion 423, and the output shaft of the second driving device 31 passes through the cylindrical portion 423 and is inserted into the mounting hole 3212 on the second cleaning element 32. Alternatively, in other examples, the cylindrical portion 423 is not formed on the first housing 421, and the second driving device 31 is inserted into the receiving cavity 3211 and fixedly connected to the first housing 421.

[0110] In one example, the cylindrical portion 423 is interference-fitted with the second cleaning element 32; or, in other examples, the cylindrical portion 423 is threadedly connected to the second cleaning element 32.

[0111] In one example, the second drive unit 31 is fixed to the cylindrical part 423 by means of connectors such as screws or bolts.

[0112] In one example, see Figure 5One end of the second drive device 31, away from the mounting hole 3212 on the second cleaning element 32, extends into the cavity formed by the first housing 421 and the second housing 422; or, in other examples, one end of the second drive device 31, away from the mounting hole 3212 on the second cleaning element 32, is located inside the cylindrical portion 423.

[0113] In one example, see Figure 5 An annular limiting plate 424 is formed on the circumferential inner side of the cylindrical body 423. The annular limiting plate 424 is disposed away from the first housing 421, and the second driving device 31 abuts against the annular limiting plate 424. The annular limiting plate 424 is provided to position the second driving device 31 within the cylindrical body 423.

[0114] In one example, see Figure 5 The second cleaning element 32 includes a support portion 321 and a cleaning portion 322. The cleaning portion 322 is sleeved on the support portion 321. The support portion 321 has a receiving cavity 3211 and a mounting hole 3212. The outer periphery of the cleaning portion 322 is provided with bristles 3221.

[0115] In this embodiment of the application, by further defining the installation method of the second driving device 31, the structure of the second cleaning component 30 can be made compact while enabling the second driving device 31 to drive the second cleaning element 32 to rotate.

[0116] In one embodiment, the cleaning seat 100 further includes a detection device for detecting the current of the first drive device 41 in the lifting structure 40. The detection device is connected to a controller. When the first drive device 41 is activated, the controller can respond to the current increase signal transmitted by the detection device to control the first drive device 41 to stop activating.

[0117] After the first drive device 41 is connected to the current, the first drive device 41 can operate; when the resistance from the load increases, it will hinder the rotation of the output shaft of the first drive device 41, and thus the current needs to be increased so that the first drive device 41 can continue to operate.

[0118] When the second cleaning component 30 is in the first position, if the controller receives a strong cleaning signal, the controller can control the first driving device 41 to move the second cleaning component 30 towards the second position where it contacts the surface to be cleaned. The detection device detects the current of the first driving device 41 in real time. When the second cleaning component 30 is in the second position, the second cleaning component 30 is in contact with the surface to be cleaned. If the first driving device 41 continues to move the second cleaning component 30, the contact between the second cleaning component 30 and the surface to be cleaned will increase the resistance when the first driving device 41 moves the second cleaning component 30, causing the current of the first driving device 41 to increase. The detection device transmits the detected current signal to the controller. In response to the increased current signal transmitted by the detection device, the controller controls the first driving device 41 to stop moving, so that the second cleaning component 30 stays in the second position.

[0119] When the second cleaning component 30 is in the second position, if the controller receives a signal that the stubborn stains have been removed, the controller can control the first drive device 41 to move the second cleaning component 30 towards the first position. The detection device detects the current of the first drive device 41 in real time. When the second cleaning component 30 is in the first position, the second cleaning component 30 is in contact with the bottom surface (fourth tank wall 114) of the receiving tank 11. If the first drive device 41 continues to move the second cleaning component 30, the contact between the second cleaning component 30 and the fourth tank wall 114 will increase the resistance when the first drive device 41 moves the second cleaning component 30, which will increase the current of the first drive device 41. The detection device will transmit the detected current signal to the controller. In response to the increased current signal transmitted by the detection device, the controller will control the first drive device 41 to stop moving, so that the second cleaning component 30 stays in the first position.

[0120] In this embodiment of the application, by setting a detection device to detect the current of the first driving device 41 in the lifting structure 40, the controller can accurately control the first driving device 41 to stay in the first position or the second position.

[0121] It is worth noting that the above description describes the detection device for detecting the current of the first drive device 41 in the lifting structure 40. In other embodiments, the detection device may also include a first detection unit and a second detection unit. The first detection unit is used to detect that the second cleaning component 30 is located in a first position, and the second sensor is used to detect that the second cleaning component 30 is located in a second position.

[0122] In one example, when the second cleaning component 30 is in the second position, if the controller receives a signal that stubborn stains have been removed, the controller can control the first drive device 41 to move the second cleaning component 30 towards the first position. When the second cleaning component 30 is in the first position, the first detection unit detects that the second cleaning component 30 has been triggered, and sends a signal to the controller, which then controls the first drive device 41 to stop operating. In this example, the first detection unit can be configured as a pressure sensor or a trigger switch.

[0123] In one example, when the second cleaning component 30 is in the second position, if the controller receives a signal that the stubborn stains have been removed, the controller can control the first drive device 41 to move the second cleaning component 30 toward the first position. When the second cleaning component 30 is in the first position, the first detection unit detects the distance between the second cleaning component 30 and the bottom surface of the receiving cavity 3211 and transmits the signal to the controller. When the controller determines that the distance between the second cleaning component 30 and the bottom surface of the receiving cavity 321 is within a preset range, the controller controls the first drive device 41 to stop moving.

[0124] In one example, when the second cleaning component 30 is in the first position, if the controller receives a strong cleaning signal, the controller can control the first driving device 41 to move the second cleaning component 30 to the second position. When the second cleaning component 30 is in the second position, the first detection unit detects the image information of the second cleaning component 30 and the surface to be cleaned and sends the signal to the controller. When the controller determines that the second cleaning component 30 is in contact with the surface to be cleaned, the controller controls the first driving device 41 to stop moving.

[0125] In one embodiment, the second cleaning component 30 is electrically connected to a controller, which can control the operation of the second drive device 31 of the second cleaning component 30 in response to the second cleaning component 30 being located in a second position. That is, in this embodiment, when the controller determines that the second cleaning component 30 is located in the second position, it can control the operation of the second drive device 31 of the second cleaning component 30.

[0126] In one example, when the first driving device 41 moves the second cleaning component 30 to the second position, the detection device transmits the detected current signal to the controller in real time. When the controller determines that the current increases, it determines that the second cleaning component 30 is in the second position. In response to the current increase signal transmitted by the detection device, the controller controls the first driving device 41 to stop moving, so that the second cleaning component 30 stays in the second position. At the same time, in response to the second cleaning component 30 being in the second position, the controller controls the second driving device 31 of the second cleaning component 30 to move, so that the second cleaning component 30 cleans the stubborn stains on the surface to be cleaned.

[0127] In one example, as described above, the detection device includes a first detection unit and a second detection unit. The first detection unit detects the image information of the second cleaning component 30 and the surface to be cleaned and transmits the signal to the controller. When the controller determines that the second cleaning component 30 is in contact with the surface to be cleaned, the controller determines that the second cleaning component 30 is in a second position. The controller controls the first driving device 41 to stop operating and controls the second driving device 31 of the second cleaning component 30 to operate, so that the second cleaning component 30 cleans the stubborn stains on the surface to be cleaned.

[0128] The above embodiments describe a controller that can control the second drive device 31 of the second cleaning component 30 to operate in response to the second cleaning component 30 being in a second position. In one embodiment, the controller can control the second drive device 31 of the second cleaning component 30 to stop operating in response to a signal indicating that stubborn stains have been removed. When the second cleaning component 30 is in the second position, if the controller receives a signal indicating that stubborn stains have been removed, the controller can control the first drive device 41 to operate, thereby driving the second cleaning component 30 to move towards the first position. At the same time, the controller controls the second drive device 31 of the second cleaning component 30 to stop operating.

[0129] This embodiment provides a cleaning device, which is a handheld floor scrubber. The cleaning device includes an upright part and a cleaning seat 100 provided in any of the above embodiments. The cleaning seat 100 is hinged to the upright part.

[0130] The cleaning seat 100 contacts the surface to be cleaned to clean it. The cleaning seat 100 is hinged to the upright part. When the cleaning seat 100 is in operation, the upright part is used to move the cleaning seat 100 to clean the surface. Specifically, the cleaning objects of the cleaning equipment include tiles, floors, cement floors, glass surfaces, etc.

[0131] Regarding the upright section, the end of the upright section away from the cleaning seat 100 is a handle assembly, which is used by the user to operate and hold the device. Additionally, an operating interface is formed on the upright section, allowing the user to control the working status of the cleaning equipment.

[0132] The upright unit also includes a clean water tank and a wastewater tank. The clean water tank contains cleaning fluid, such as cleaning water, which can be supplied to the first cleaning component 20 of the cleaning seat 100 via a clean water pipeline. The wastewater tank is configured to contain recycled wastewater. When cleaning equipment is used to clean the floor, wastewater is generated on the surface being cleaned, and the wastewater can be recycled back to the wastewater tank via a wastewater recycling pipeline.

[0133] The cleaning equipment provided in this embodiment can select different cleaning modes according to different cleaning scenarios. For example, when it is necessary to clean stubborn stains on the ground, the powerful cleaning mode of the cleaning equipment can be activated, and the second cleaning unit will work to clean the surface to be cleaned in a powerful cleaning mode.

[0134] The cleaning device provided in this embodiment, since the second cleaning unit only contacts the floor when needed, allows the cleaning seat 100 to clean stubborn stains without causing scratches or other damage to the floor.

[0135] This embodiment provides a cleaning system, including a pile and the cleaning equipment provided in any of the above embodiments. The pile is configured to support the cleaning equipment. After completing the cleaning operation, the cleaning equipment is typically placed on the pile, which supports and secures the equipment.

[0136] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
