Description

Technical Field

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

[0002] With the improvement of living standards, cleaning equipment has been widely used because it saves time and effort. Cleaning equipment cleans the surface by interfering with the cleaning components. When the surface needs to be mopped, the cleaning components need to be wetted before mopping. Cleaning equipment has a self-cleaning characteristic of "living water cleaning." One of the most important parameters affecting the living water cleaning ability is the wastewater recovery rate. The wastewater recovery rate is the ability to scrape wastewater off the cleaning components. The stronger this ability, the stronger the self-cleaning ability of the cleaning components, and the stronger the corresponding living water cleaning.

[0003] The aforementioned wastewater recovery structure can recover wastewater from unidirectional rotating cleaning components. However, as people's demands for quality of life increase, unidirectional rotating cleaning components can no longer meet their needs. As a result, cleaning components that can rotate in both directions have appeared on the market. For such bidirectional rotating cleaning components, the existing wastewater recovery structure cannot recover wastewater from the cleaning components in both rotation directions at the same time, which seriously affects the user experience. Summary of the Invention

[0004] One of the technical problems that this disclosure aims to solve is that existing wastewater recovery structures cannot simultaneously recover wastewater from cleaning components that rotate in both directions, which seriously affects the user experience.

[0005] To address the aforementioned technical problems, this disclosure provides a cleaning mechanism, comprising: Cleaning support with a receiving cavity; A cleaning component is rotatably disposed within the receiving cavity; A scraping mechanism includes a scraping section and a first wastewater chamber and a second wastewater chamber located on both sides of the scraping section. The scraping section abuts against the surface of the cleaning component. The first wastewater chamber is configured to receive wastewater scraped from the cleaning component by the scraping section when the cleaning component rotates in the reverse direction. The second wastewater chamber is configured to receive wastewater scraped from the cleaning component by the scraping section when the cleaning component rotates in the forward direction.

[0006] On the other hand, this disclosure also provides a cleaning device, wherein the cleaning device includes a body and a cleaning mechanism as described in any of the above embodiments, and the cleaning mechanism is disposed on the body.

[0007] Through the above technical solution, when the cleaning component rotates in the forward and reverse directions, the first and second sewage chambers on both sides of the scraping part can respectively recycle and collect the sewage on the cleaning component, thereby improving the sewage recycling efficiency of the cleaning mechanism and thus improving the user experience.

[0016] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0017] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0018] Existing wastewater recovery structures for cleaning equipment can recover wastewater from cleaning components that rotate in one direction. However, as people's demands for quality of life increase, cleaning components that rotate in one direction can no longer meet their needs. As a result, cleaning components that can rotate in both directions have appeared on the market. For these bidirectional rotating cleaning components, existing wastewater recovery structures cannot recover wastewater from the cleaning components in both rotation directions at the same time, which seriously affects the user experience.

[0019] In view of this, this application provides a cleaning mechanism and cleaning equipment. By providing a first sewage chamber 26 and a second sewage chamber 27 on both sides of the scraping part 29, the first sewage chamber 26 and the second sewage chamber 27 can respectively recycle and collect sewage on the cleaning part 11 when the cleaning part 11 rotates in the forward and reverse directions, thereby improving the sewage recycling efficiency of the cleaning mechanism and improving the user experience.

[0020] The cleaning equipment described in this application can be a self-propelled cleaning robot or a handheld floor scrubber. The self-propelled cleaning robot can be a mopping robot or a combined sweeping and mopping robot, etc.

[0021] In the following embodiments, a self-moving cleaning robot is used as an example to describe some of its components. However, those skilled in the art will understand that other robots that include the cleaning mechanism or scraping mechanism of this application can also have the beneficial effects brought about by the cleaning mechanism or scraping mechanism of this application.

[0022] The cleaning equipment has a main body, which can house various components. The main body can be any shape, such as cylindrical, elliptical, or D-shaped.

[0023] The cleaning equipment also includes a walking system conventionally found on existing cleaning equipment, used to drive the main body of the equipment to move independently across the surface to be cleaned. The walking system includes at least a driver and drive wheels, which rotate under the action of the driver. There are generally two drive wheels, symmetrically located at the bottom of the main body of the equipment. The specific structure of the walking system and the connection structure between the walking system and the main body of the equipment can be found in the relevant structural descriptions of existing cleaning equipment, and will not be repeated here.

[0024] To perform its cleaning function, a cleaning device must include at least a cleaning mechanism. The cleaning mechanism is detachably connected to the main body of the device, and the detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, or the like.

[0025] The cleaning mechanism is configured for wet mopping. The cleaning mechanism includes a cleaning component 11 and a cleaning bracket 30. The cleaning component 11 is mounted on the cleaning bracket 30. The cleaning component 11 includes, but is not limited to, a roller-type cleaning component and a track-type cleaning component to achieve wet cleaning.

[0026] In some embodiments, the cleaning device may further include side brushes and roller brushes, which are located at the bottom of the device body. Along the travel direction of the device body, both the side brushes and roller brushes are positioned in front of the cleaning mechanism. The side brushes may be located at the edge of the device body and can rotate via a rotating mechanism, such as a motor, a combination of a motor and a reducer. When the side brushes rotate, they can gather debris from the edge of the device body towards the inside of the device body, thereby expanding the cleaning range of the cleaning device. The side brushes can be rubber strips or bristles, as long as they can clean the ground; there are no limitations. The roller brushes are rotatably mounted in a roller brush cavity at the bottom of the device body. During rotation, the roller brushes can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; this embodiment does not limit the number.

[0027] The side brushes and roller brushes are positioned in front of the cleaning mechanism along the direction of travel of the main body of the equipment. This facilitates the cleaning operation of dry sweeping followed by wet mopping, and also makes the layout of the internal space of the main body of the equipment easier.

[0028] In addition to the above, the cleaning equipment may also include a sensing system and a control system. The sensing system and the control system are electrically connected. The sensing system includes an LDS located on top of the equipment body, a buffer and vision sensor located at the front of the equipment body, and an edge sensor located on the front side wall of the equipment body. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the equipment body and obstacles. The control system uses this distance to control the cleaning equipment to perform corresponding actions. For example, controlling the cleaning equipment to perform obstacle avoidance, edge cleaning, and returning to the base station.

[0029] Please see Figures 1-4 The cleaning mechanism provided in this application includes a cleaning bracket 30, a cleaning component 11, and a stain scraping mechanism.

[0030] The cleaning bracket 30 provides a mounting carrier for the cleaning component 11 and some parts of the cleaning mechanism to facilitate the assembly of the cleaning mechanism. The cleaning bracket 30 is connected to the main body of the cleaning equipment. The connection methods between the cleaning bracket 30 and the main body of the equipment include, but are not limited to, bolt connection and snap-fit ​​connection, so that the cleaning mechanism can be installed on the main body of the equipment.

[0031] The cleaning bracket 30 is provided with a receiving cavity, in which the cleaning component 11 is rotatably disposed. The receiving cavity provides a protective space for the cleaning component 11, reducing the risk of impact to the cleaning component 11 and limiting the splashing direction of sewage and other dirt on the cleaning component 11. This prevents sewage and other dirt on the cleaning component 11 from splashing onto the main body of the equipment or the area in front of or behind the surface to be cleaned, thereby reducing contamination of the surface to be cleaned and ensuring the cleaning effect.

[0032] The cleaning component 11 is a rotary cleaning component. The cleaning component 11 can rotate in both the forward and reverse directions. The terms "forward" and "reverse" are relative concepts, indicating that the cleaning component 11 can rotate in opposite directions. For example, if forward rotation represents the counterclockwise direction, then reverse rotation represents the clockwise direction; if forward rotation represents the clockwise direction, then reverse rotation represents the counterclockwise direction.

[0033] In one example, the rotary cleaning component 11 is a roller-type cleaning cloth, which is rotatably disposed within the receiving cavity. The drive module of the cleaning component 11 drives the roller-type cleaning cloth to rotate, and the roller-type cleaning cloth interferes with the surface to be cleaned to clean the surface. In other examples, the rotary cleaning component 11 is a tracked cleaning cloth, which is mounted on the cleaning bracket 30 via an inner support bracket 12. When the drive assembly 40 of the cleaning component 11 drives the inner support bracket 12 to rotate, the inner support bracket 12 causes the tracked cleaning cloth to roll along the surface to be cleaned, and the tracked cleaning cloth interferes with the surface to be cleaned to clean the surface.

[0034] Of course, as some alternatives, the cleaning component 11 can also be other wet cleaning components 11, which will not be elaborated in this application.

[0035] The scraping mechanism is rotatably mounted on the side of the cleaning bracket 30 facing the receiving cavity. There are various options for the rotatable mounting method of the scraping mechanism and the cleaning bracket 30. For example, the scraping mechanism and the cleaning bracket 30 can be rotatably connected by a hinge, by a rotating shaft, or by a bearing. Alternatively, one of the scraping mechanism and the cleaning bracket 30 can be provided with an arc-shaped guide, and the other can be provided with a follower that cooperates with the arc-shaped guide. The follower moves along the arc-shaped guide so that the scraping mechanism and the cleaning bracket 30 rotate relative to each other.

[0036] The scraping mechanism is used to interfere with the cleaning component 11 to scrape off dirt from the cleaning component 11 when it moves. The cleaning component 11 moves during the cleaning process of the surface to be cleaned. Due to the interference with the scraping mechanism, dirt such as sewage is scraped off by the scraping mechanism, thereby adjusting the moisture content of the cleaning component 11.

[0037] The scraping mechanism is rotatably mounted on the side of the cleaning bracket 30 facing the receiving cavity. The receiving cavity can prevent sewage on the cleaning component 11 from splashing outside the cleaning mechanism, and can also prevent sewage at the point of interference between the scraping mechanism and the cleaning component 11 from splashing outside the cleaning mechanism, thereby reducing the risk of secondary pollution and improving the cleaning effect.

[0038] The cleaning mechanism also includes a drive mechanism, which is installed on the cleaning bracket 30. The drive mechanism can be fixedly installed on the cleaning bracket 30. The drive mechanism drives the scraping mechanism to rotate relative to the cleaning bracket 30, so as to actively adjust the amount of interference between the scraping mechanism and the cleaning component 11. Different amounts of interference can adjust the moisture content of the cleaning component 11 to meet the usage requirements in different scenarios and improve the cleaning effect on the surface to be cleaned or the self-cleaning effect of the cleaning component 11.

[0039] A larger interference amount can reduce the moisture content of the cleaning component 11. For example, when the cleaning equipment detects a puddle of water on the ground, the moisture content of the cleaning component 11 is about to surge. To ensure the continuous water absorption effect in this area, the interference amount between the scraping mechanism and the cleaning component 11 is adjusted to be larger. Alternatively, when the cleaning equipment is self-cleaning at the base station, to ensure the self-cleaning effect, the wastewater of the cleaning component 11 is scraped off by the scraping mechanism with a larger interference amount, allowing the cleaning component 11 to absorb more clean water for self-cleaning. Or, when the cleaning equipment needs a lower moisture content when it leaves the base station after self-cleaning, the interference amount between the scraping mechanism and the cleaning component 11 is dynamically adjusted to a position with a larger interference amount to reduce the moisture content of the cleaning component 11. Or, when the moisture content of the cleaning component 11 is low, to ensure that the wastewater on the cleaning component 11 is scraped off cleanly, the interference amount between the scraping mechanism and the cleaning component 11 is adjusted to be larger to effectively scrape off the wastewater on the cleaning component 11.

[0040] The moderate interference ensures that the cleaning component 11 has a certain amount of moisture content. For example, during normal mopping, it balances the moisture content with the mopping ability of the surface to be cleaned, while also ensuring a balanced motor load on the cleaning component 11.

[0041] A lower interference level ensures that the cleaning component 11 has a larger amount of water. For example, when the cleaning equipment is soaking water for self-cleaning of the base station, the water content of the cleaning component 11 needs to be increased. The scraping mechanism is dynamically adjusted to a lower interference level position so that the cleaning component 11 can be soaked in more water. Or, if the cleaning equipment detects that the motor current driving the cleaning component 11 is abnormally high during cleaning, which may be due to foreign objects or other issues, the scraping mechanism is dynamically adjusted to a lower interference level position to reduce the friction between the scraping mechanism and the cleaning component 11, reduce the load on the motor driving the cleaning component 11, and reduce the risk of motor overload and burnout.

[0042] Based on the aforementioned large, medium, and low interference levels, users can also manually adjust the interference between the scraping mechanism and the cleaning component 11 according to their desired moisture content. For example, to reduce water stains on the surface to be cleaned, the user can increase the interference level and decrease the moisture content of the cleaning component 11. To improve the cleaning effect, the user can decrease the interference level, allowing the cleaning component 11 to have a higher moisture content and thus improve the cleaning effect. Manual adjustment can be performed via an app on a mobile phone, tablet, or other electronic device. Users can also control the cleaning device or base station directly via voice commands, or by issuing commands through other buttons to adjust the interference between the scraping mechanism and the cleaning component 11.

[0043] Please see Figure 4 In some embodiments, the scraping mechanism includes a scraping part 29 and a first wastewater chamber 26 and a second wastewater chamber 27 located on both sides of the scraping part 29. The scraping part 29 abuts against the surface of the cleaning member 11. The first wastewater chamber 26 is configured to receive wastewater scraped from the cleaning member 11 by the scraping part 29 when the cleaning member 11 rotates in the reverse direction. The second wastewater chamber 27 is configured to receive wastewater scraped from the cleaning member 11 by the scraping part 29 when the cleaning member 11 rotates in the forward direction.

[0044] The first wastewater chamber 26 and the second wastewater chamber 27 are used to collect the dirt scraped by the scraping mechanism. Both the first wastewater chamber 26 and the second wastewater chamber 27 have wastewater inlets, allowing wastewater from the cleaning component 11 to enter the corresponding wastewater chamber. The first wastewater chamber 26 and the second wastewater chamber 27 provide a space for collecting and temporarily storing the wastewater and other dirt scraped by the scraping mechanism from the cleaning component 11. The cleaning equipment only needs to extract the dirt from the first wastewater chamber 26 and the second wastewater chamber 27, making it convenient to extract the dirt into the wastewater tank of the cleaning equipment.

[0045] The scraping part 29 is used to interfere with the cleaning component 11 to scrape off dirt from the cleaning component 11. The scraping part 29 is disposed between the first sewage chamber 26 and the second sewage chamber 27, and is close to the sewage openings of the first sewage chamber 26 and the second sewage chamber 27. When the cleaning component 11 moves relative to the scraping part 29, the scraping part 29 scrapes off sewage and other dirt from the cleaning component 11. The scraped sewage and other dirt enter the corresponding sewage chamber through the corresponding sewage opening, thereby achieving the collection and temporary storage of dirt.

[0046] For example, the scraping part 29 can abut against different positions of the cleaning member 11. For instance, the cleaning member 11 is a tracked cleaning cloth, which includes two straight sections and arc-shaped sections at both ends of the straight sections. The scraping part 29 can abut against the straight sections, the arc-shaped sections, or the parts where the straight sections and the arc-shaped sections meet. When the tracked cleaning cloth moves relative to the scraping part 29, the scraping part 29 can scrape off the sewage and other dirt from the tracked cleaning cloth.

[0047] For example, the end of the scraping part 29 is arc-shaped, for example, the end of the scraping part 29 is rounded to avoid the scraping part 29 from damaging the cleaning part 11.

[0048] Please see Figure 3 and Figure 4 In some embodiments, the scraping mechanism includes a scraping element 20, which includes a base 24, a scraper 23, a first plate 21, and a second plate 22. One side of each of the scraper 23, the first plate 21, and the second plate 22 is fixedly connected to the base 24, and the other side extends away from the base 24. The side of the scraper 23 away from the base 24 is a scraping section 29, and the scraper 23 is located between the first plate 21 and the second plate 22. The base 24, the first plate 21, and the scraper 23 form a first wastewater chamber 26; the base 24, the second plate 22, and the scraper 23 form a second wastewater chamber 27.

[0049] The scraper 23, the first plate 21, and the second plate 22 are fixedly connected to the base 24 by methods including but not limited to integral molding and welding. Preferably, the fixed connection method is integral molding. The scraper 23, the first plate 21, the second plate 22, and the base 24 can be made of plastic. Plastic has strong corrosion resistance and is lightweight, which can reduce the overall weight of the cleaning mechanism. The scraper 23, the first plate 21, the second plate 22, and the base 24 can also be made of metal, such as copper or aluminum. Metal is not easily deformed and can provide constant pressure on the cleaning component 11, thereby improving the scraping effect of the scraping mechanism on the cleaning component 11. The materials of the scraper 23, the first plate 21, the second plate 22, and the base 24 can also be such that some parts are made of plastic and others are made of metal. For example, the first plate 21, the second plate 22, and the base 24 are made of plastic, while the scraper 23 is made of metal. In this way, the metal scraping part 29 is not easily deformed, which can improve the scraping effect of the scraping mechanism on the cleaning part 11. At the same time, the first plate 21, the second plate 22, and the base 24 are made of plastic, which can reduce the overall weight of the cleaning mechanism.

[0050] The scraper 23 and the first plate 21, as well as the scraper 23 and the second plate 22, are spaced apart. The space between the scraper 23 and the first plate 21 forms a first sewage chamber 26, and the space between the scraper 23 and the second plate 22 forms a second sewage chamber 27. The side of the first sewage chamber 26 away from the base 24 is open to form a sewage inlet; the side of the second sewage chamber 27 away from the base 24 is also open to form a sewage inlet. Sewage on the cleaning member 11 can enter the corresponding sewage chamber through the corresponding sewage inlet.

[0051] Furthermore, the scraper 23, excluding the scraping portion 29, is inclined upwards, and the second plate 22 is also inclined upwards. This arrangement allows the bottom walls of both the first sewage chamber 26 and the second sewage chamber 27 to be inclined upwards. When sewage is located in the first sewage chamber 26 and the second sewage chamber 27, the upwardly inclined bottom walls can restrict the outward flow of sewage, thus achieving the effect of temporarily storing sewage. In addition, the scraping portion 29 of the scraper 23 is inclined downwards towards the cleaning component 11, and there is a rounded transition between the scraping portion 29 and the upwardly inclined portion of the scraper 23. This arrangement allows the scraping portion 29 to press downwards against the cleaning component 11, thereby enabling the scraping portion 29 to scrape away the sewage on the cleaning component 11.

[0052] Please see Figure 4 In some embodiments, the scraping portion 29 protrudes from the side of the first plate 21 and the second plate 22 away from the base 24, so that the scraping portion 29 abuts against the cleaning member 11. With this arrangement, on the one hand, the end of the scraper 23 away from the base 24 (i.e., the scraping portion 29) can protrude from the first plate 21 and the second plate 22, so that the scraping portion 29 presses against the cleaning member 11 to scrape the cleaning member 11. On the other hand, the protruding scraping portion 29 can form a distance difference with the first plate 21 and the second plate 22, thereby extending the receiving area of ​​the sewage inlet of the first sewage chamber 26 and the sewage inlet of the second sewage chamber 27. When the sewage on the cleaning member 11 is scraped up by the scraping portion 29, the sewage will splash briefly. The extended receiving area can provide sufficient buffer distance for the splashed sewage, so that the sewage can fall into the corresponding sewage inlet. This allows more sewage scraped from the cleaning member 11 to enter the corresponding sewage chamber, thereby further improving the sewage recovery effect of the scraping mechanism.

[0053] In some embodiments, the scraping member 20 has a rotating part 25, which is rotatably connected to the cleaning bracket 30. The cleaning mechanism also includes a drive assembly 40, which is mounted on the cleaning bracket 30. The drive assembly 40 is used to drive the scraping mechanism to rotate relative to the cleaning bracket 30, so as to actively adjust the interference fit between the scraping member 29 and the cleaning member 11.

[0054] The rotating part 25 is fixed to the base 24 and rotatably connected to the cleaning bracket 30. When the rotating part 25 rotates relative to the cleaning bracket 30, it drives the base 24, scraper 23, first plate 21, and second plate 22 to rotate relative to the cleaning bracket 30, thereby adjusting the relative position of the scraping part 29 and the cleaning part 11, and thus adjusting the amount of interference between the scraping part 29 and the cleaning part 11. There are several options for the rotatable connection between the rotating part 25 and the cleaning bracket 30. For example, the cleaning bracket 30 is provided with a rotating groove 31, and the rotating part 25 is rotatably installed in the rotating groove 31; or, the cleaning bracket 30 is provided with a bearing, and the rotating part 25 is fixed to the inner ring of the bearing, so that the rotating part 25 rotates relative to the cleaning bracket 30; or, the cleaning bracket 30 is provided with a rotating shaft, and the rotating shaft at least partially extends into the rotating part 25 and is rotatably connected to the rotating part, etc.

[0055] In some embodiments, the rotating part 25 is fixedly connected to the lower part of the base 24. The fixed connection method includes, but is not limited to, integral molding, welding, etc. Preferably, the rotating part 25 is integrally molded into the base 24. To facilitate the spatial layout of the cleaning mechanism, the drive component 40 can be set in the upper area of ​​the cleaning mechanism, which can reduce the risk of the drive component 40 being damaged by impact. The rotation axis of the scraping mechanism is far from the drive component 40, which can facilitate the drive component 40 to drive the scraping mechanism to rotate relative to the cleaning bracket 30, reduce the risk of the scraping mechanism getting stuck, reduce the need for manual intervention in maintenance, and improve service life.

[0056] The drive assembly 40 can take various forms. For example, it can be a cylinder, the extension end of which acts on the scraper 20 to drive the scraper 20 to rotate around the rotating part 25. Alternatively, the drive assembly 40 can be a motor, gear, and rack, where the motor drives the gear to rotate, the gear drives the rack to extend and retract, and the extension end of the rack acts on the scraper 20 to drive the scraper 20 to rotate around the rotating part 25. Or, the drive assembly 40 can be a spring, the spring force acting on the scraper blade to drive the scraper 20 to rotate around the rotating part 25.

[0057] Please see Figure 3 , 4 In some embodiments, a rotating groove 31 is provided on the inner wall of the receiving cavity, and a rotating part 25 is located in the rotating groove 31. The rotating part 25 cooperates with the rotating groove 31 so that the rotating part 25 is rotatably connected to the cleaning bracket 30.

[0058] For example, the cleaning bracket 30 includes a support block disposed on the inner wall of the receiving cavity. The support block supports the rotating part 25 and the scraping mechanism. Specifically, the support block is fixedly connected to the bottom of the receiving cavity near the ground. This position provides a larger installation space for the scraping part 20, significantly increasing its volume and thus increasing the capacity of the first sewage chamber 26 and the second sewage chamber 27. Simultaneously, the greater depth of the first and second sewage chambers 26 and 27 reduces the risk of sewage spilling out, improving the cleanliness of the cleaning mechanism and reducing the possibility of secondary contamination of the surface to be cleaned. One or more support blocks can be provided; preferably, multiple support blocks are provided to provide balanced support for the scraping mechanism, ensuring the stability of the relative rotation between the scraping mechanism and the cleaning bracket 30. A rotating groove 31 is formed on the support block, and the rotating part 25 is mounted in the rotating groove 31. The rotating part 25 rotates within the rotating groove 31, allowing it to rotate relative to the cleaning bracket 30.

[0059] For example, the rotating groove 31 is an arc-shaped groove, and the rotating part 25 is installed in the arc-shaped groove and rotates along the inner wall of the arc-shaped groove. The angle of the arc-shaped groove can be selected as needed so that the rotating part 25 does not leave the arc-shaped groove. For example, the central angle of the arc-shaped groove can be a right angle, an obtuse angle, etc., and the central angle of the arc-shaped groove can also be greater than or equal to 180° to ensure that the rotating part 25 does not leave the arc-shaped groove.

[0060] Please see Figure 3 In some embodiments, the scraper 20 is provided with a protrusion 28, and the cleaning bracket 30 is provided with a limiting groove 32 for limiting the movement range of the protrusion 28. The limiting groove 32 is arc-shaped, and the center of the arc of the limiting groove 32 is located on the rotation axis of the rotating part 25. The protrusion 28 and the limiting groove 32 cooperate to limit the rotation range of the scraper 20 relative to the cleaning bracket 30.

[0061] The limiting groove 32 is arc-shaped, with its center located on the rotation axis of the rotating part. The protrusion 28 on the scraper 20 extends into the limiting groove 32 and moves along it. The cooperation between the protrusion 28 and the limiting groove 32 limits the rotation range of the scraper 20, preventing it from detaching from the cleaning bracket 30 or causing damage to the cleaning component 11 due to excessive interference. The arc shape of the limiting groove 32 ensures the stability of the limiting block's movement trajectory and avoids it occupying excessive space, thus improving the space utilization of the scraper 20.

[0062] Furthermore, the protrusion 28 is located on the upper part of the scraper 20 and on the side of the scraper 20 away from the rotating part 25. The support block provides support for the rotating part 25; in other words, the support block restricts the downward movement of the scraper 20. The arc-shaped limiting groove 32 and the protrusion 28 limit the top of the scraper 20, reducing the upward movement space of the scraper 20. By limiting the upper and lower parts of the scraper 20 through the limiting groove 32 and the protrusion 28 respectively, the installation stability of the scraper 20 is ensured, and the scraper 20 is prevented from detaching from the cleaning bracket 30.

[0063] Please see Figure 1 , 2 In some embodiments, the drive assembly 40 includes a drive member and a linkage member. The linkage member is movably disposed on the cleaning bracket 30 and is linked to the scraper member 20. The drive member is configured to drive the linkage member to move so that the scraper member 20 rotates around the rotating part 25 through the linkage member.

[0064] Please see Figure 2 In some embodiments, the linkage includes a swing arm 42, which is rotatably connected to the cleaning bracket 30. The swing arm 42 has a first end and a second end. The first end is linked to the drive member, and the second end abuts against the scraper 20. The drive member is configured to drive the swing arm 42 to swing so that the scraper 20 rotates around the rotating part 25 through the swing arm 42.

[0065] The swing arm 42 is mounted on the upper part of the cleaning bracket 30, which can effectively reduce the occupation of the receiving cavity and reduce the risk of interference between the swing arm 42 and other components of the cleaning mechanism during movement. The cleaning bracket 30 is provided with a through hole, and the second end extends through the through hole into the receiving cavity to abut against the scraper 20. The driving member is used to drive the swing arm 42 to swing. The driving member can be a cylinder or a combination of a motor, gear and rack as described in the above embodiment. The telescopic end of the driving member can act on the first end to drive the second end to swing. Since the second end acts on the scraper 20, the second end can drive the scraper 20 to rotate around the rotating part 25 during movement to adjust the amount of interference between the scraper 29 and the cleaning member 11.

[0066] Please see Figure 2 In some embodiments, the linkage also includes a cam 41, with the first end abutting against the cam 41, and the drive is configured to drive the cam 41 to rotate so that the scraper 20 rotates around the rotating part 25 via the swing arm 42.

[0067] The drive unit can drive the cam 41 to rotate. The cam 41 abuts against the first end of the rocker arm 42. By changing the outer diameter of the cam 41, the second end of the rocker arm 42 can be driven to swing, thereby driving the scraper 20 to rotate around the rotating part 25. The drive unit can take various forms. For example, the drive unit can be a motor, with the motor's output shaft directly fixed to the cam 41. Alternatively, the drive unit can be a combination of a motor and a gearbox, with the motor's output shaft coaxially connected to the gearbox's input shaft, and the gearbox's output shaft connected to the cam 41.

[0068] In other embodiments, the swing arm 42 may be omitted, and the cam 41 may directly abut against the scraper 20, thereby directly driving the scraper 20 to rotate around the rotating part 25 by the change in the outer diameter of the cam 41.

[0069] In some embodiments, the drive unit includes a drive shaft 43 and a drive motor 44. The drive shaft 43 is rotatably connected to the cleaning bracket 30, the cam 41 is fixedly mounted on the drive shaft 43, and the drive motor 44 is used to drive the drive shaft 43 to rotate.

[0070] The drive motor 44 is installed on the cleaning bracket 30. The drive motor 44 can be installed at different positions on the cleaning bracket 30, such as the upper part or the side of the cleaning bracket 30.

[0071] The drive motor 44 is fixedly mounted on the cleaning bracket 30, and the mounting method includes, but is not limited to, bolt connection. The transmission shaft 43 is disposed on the cleaning bracket 30 and is connected to the drive motor 44 so that the drive motor 44 drives the transmission shaft 43 to rotate relative to the cleaning bracket 30.

[0072] The drive shaft 43 is rotatably mounted on the cleaning bracket 30. The relative rotation of the drive shaft 43 and the cleaning bracket 30 can be achieved in several ways. For example, the drive shaft 43 on the cleaning bracket 30 may have a rotating shaft 47 seat with a hole, into which the drive shaft 43 is inserted and rotates relative to the hole, thus achieving relative rotation between the drive shaft 43 and the cleaning bracket 30. Alternatively, the rotating shaft 47 seat may have a bearing, through which the drive shaft 43 passes and is fixed to the inner ring of the bearing, allowing relative rotation between the drive shaft 43 and the cleaning bracket 30. Of course, the drive shaft 43 can also be rotatably mounted on the cleaning bracket 30 in other ways.

[0073] Cam 41 is mounted on drive shaft 43, which drives cam 41 to rotate, thereby causing swing arm 42 to rotate relative to cleaning bracket 30. Cam 41 is fixedly connected to drive shaft 43. The fixed connection method can be selected in various ways. For example, cam 41 is provided with a through hole, and drive shaft 43 is interference-fitted with the through hole to achieve relative fixation between cam 41 and drive shaft 43; or cam 41 and drive shaft 43 are connected by a pin, bolts, etc.

[0074] The cam 41 drives the first end to move, which in turn drives the second end to rotate the swing arm 42 relative to the cleaning bracket 30, thereby driving the scraper 20 to rotate around the rotating part 25. The swing arm 42 forms a lever, which facilitates the cam 41 to adjust the position of the scraper 20. At the same time, the swing arm 42 can also have a large length, which facilitates the contact between the swing arm 42 and the scraper 20 and reduces the size of the cam 41.

[0075] In some embodiments, the outer periphery of the cam 41 is a smoothly transitioning curve, and the amount of interference between the scraping mechanism and the cleaning component 11 can be steplessly adjusted within a certain range by controlling the rotation angle of the drive motor 44. In other embodiments, the outer periphery of the cam 41 may also have multiple endpoints, and the amount of interference between the scraping component 20 and the cleaning component 11 can be precisely adjusted by controlling the rotation of the drive motor 44 to a preset angle.

[0076] Please see Figure 1 , 2 In some embodiments, a shielding part 46 is provided on the drive shaft 43, and an optical coupler 45 is provided on the cleaning bracket 30. The optical coupler 45 can detect whether the shielding part 46 is in the position of the optical coupler 45. When the shielding part 46 is in the position of the optical coupler 45, a specific area of ​​the cam 41 contacts the swing arm 42.

[0077] The optical coupler 45 includes a light emitter and a light receiver spaced apart. The light emitter emits a light beam, and the light receiver receives the light beam. A detection optical path can be formed between the light emitter and the light receiver. The optical coupler 45 is electrically connected to the control system of the cleaning equipment. When the blocking part 46 is in the position of the optical coupler 45, the blocking part 46 is located between the light emitter and the light receiver, blocking the detection optical path. At this time, the optical coupler 45 outputs a first signal to the control system. When the blocking part 46 is not in the position of the optical coupler 45, the light receiver can receive the detection light beam. At this time, the optical coupler 45 outputs a second signal to the control system. The control system of the cleaning equipment determines whether the blocking part 46 is located at the target position (i.e., the position of the optical coupler 45) through the first and second signals, and then determines whether a specific area of ​​the cam 41 abuts against the first end of the swing arm 42.

[0078] It should be noted that the aforementioned specific area can refer to any of the following: 1. When the interference between the scraping part 29 and the cleaning part 11 is at its maximum, the outer peripheral portion corresponding to the first end of the cam 41 and the rocker arm 42. In this way, by determining whether the blocking part 46 is located at the target position, it can be determined whether a specific area of ​​the cam 41 abuts against the first end of the rocker arm 42, and further determined whether the interference between the scraping part 29 and the cleaning part 11 has reached its maximum.

[0079] 2. When the interference between the scraping part 29 and the cleaning part 11 is minimal (the scraping part 29 is about to detach from the cleaning part 11), the outer periphery of the cam 41 and the first end of the rocker arm 42 is located. In this way, by determining whether the blocking part 46 is located at the target position, it can be determined whether a specific area of ​​the cam 41 abuts against the first end of the rocker arm 42, and further determined whether the interference between the scraping part 29 and the cleaning part 11 has reached its minimum.

[0080] Please see Figure 3 , 4 In some embodiments, the side of the second plate 22 facing the cleaning member 11 is the bonding surface. During the rotation of the cleaning member 11, the bonding surface is bonded to the cleaning member 11 to clean the surface of the cleaning member 11.

[0081] For example, the shape of the side of the second plate 22 facing the cleaning member 11 is set to be similar to the surface shape of the cleaning member 11 to form a bonding surface. In this way, the bonding surface can increase the contact area between the second plate 22 and the cleaning member 11. When the bonding surface is attached to the surface of the cleaning member 11, the larger bonding area can enable the second plate 22 to effectively clean the dirt on the surface of the cleaning member 11, reducing the possibility of dirt getting tangled on the cleaning member 11 or embedded inside the cleaning member 11.

[0082] Please see Figure 1 In some embodiments, the cleaning mechanism further includes a sludge suction mechanism, the sludge suction port of which is connected to the first sewage chamber 26 and the second sewage chamber 27, and the sludge suction mechanism is configured to suction sewage from the first sewage chamber 26 and the second sewage chamber 27.

[0083] For example, the sewage suction mechanism has two suction pipes and one discharge pipe. The two suction pipes can be connected to the suction port of the sewage suction mechanism through a pipe, and the discharge pipe can be connected to the discharge port of the sewage suction mechanism. The two suction pipes are respectively connected to the first sewage chamber 26 and the second sewage chamber 27, and the discharge pipe is connected to the sewage tank of the cleaning equipment. In this way, the sewage suction mechanism can pump the sewage in the first sewage chamber 26 and the second sewage chamber 27 into the discharge pipe through the two suction pipes, and after being guided by the discharge pipe, finally discharge it into the sewage tank of the cleaning equipment.

[0084] In some embodiments, the sludge suction mechanism includes a sludge suction member and a first sealing member 51. The first sealing member 51 is sealed to one end of the sludge scraper 20 along its length. The first sealing member 51 has a sludge discharge channel communicating with the first sewage chamber 26 and the second sewage chamber 27. The sludge suction port of the sludge suction member is connected to the sludge discharge channel.

[0085] For example, the sludge suction component can be a pump such as a water pump or a peristaltic pump that can transport liquids. The sludge suction component can be installed in other parts of the cleaning equipment besides the cleaning mechanism, or it can be installed on the cleaning mechanism itself. The sludge suction component has the aforementioned suction port and discharge port. Two suction pipes can be connected to the suction port of the sludge suction component via a single pipe, and a discharge pipe can be connected to the discharge port of the sludge suction component. The first sealing member 51 can have two discharge channels, one of which is connected to the first sewage chamber 26, and the other is connected to the second sewage chamber 27. The two suction pipes can be connected to the two discharge channels in a one-to-one correspondence. In this way, the sludge suction component can draw sewage from the first sewage chamber 26 and the second sewage chamber 27 into the discharge pipe via the two suction pipes, and after being guided by the discharge pipe, finally discharge it into the sewage tank of the cleaning equipment.

[0086] In other examples, the sludge suction component can be a pump such as a water pump or a peristaltic pump that can transport liquids. The sludge suction component has the aforementioned sludge suction port and sludge discharge port. The sludge discharge channel on the first seal 51 connects to both the first sewage chamber 26 and the second sewage chamber 27. The sludge suction port of the sludge suction component is connected to a sludge suction pipe, which is connected to the sludge discharge channel. In addition, the sludge discharge port of the sludge suction component is connected to a sludge discharge pipe. In this way, the sludge suction component can draw sewage from the first sewage chamber 26 and the second sewage chamber 27 into the sludge discharge pipe through the sludge suction pipe, and after being guided by the sludge discharge pipe, finally discharge it into the sewage tank of the cleaning equipment.

[0087] The first sealing element 51 has a sealing effect. The first sealing element 51 is made of flexible rubber and is detachably connected to one end of the scraper 20. For example, the first sealing element 51 has an insertion portion, the number of which corresponds one-to-one with the number of sewage chambers in the scraper 20; that is, there are two insertion portions. The outer contours of the two insertion portions are respectively adapted to the inner cavities of the first sewage chamber 26 and the second sewage chamber 27. The first sealing element 51 can be inserted into the first sewage chamber 26 and the second sewage chamber 27 through the two insertion portions, thereby sealing the first sewage chamber 26 and the second sewage chamber 27. To further improve the sealing effect, the insertion portions are interference-fitted into the corresponding sewage chambers. Furthermore, the first sealing element 51 can achieve a plug-in fit with the scraper 20 through the insertion portions, realizing a detachable connection between the first sealing element 51 and the scraper 20. When blockage occurs in the first sewage chamber 26 and / or the second sewage chamber 27, it is easy to disassemble for cleaning. In other examples, the first seal 51 can also be directly sleeved on the end of the scraper 20, and the port of the scraper 20 can be sealed by the flexibility of the first seal 51.

[0088] Please see Figure 1In some embodiments, the sludge suction mechanism further includes a second seal 52, which is sealed to the end of the sludge scraper 20 away from the first seal 51.

[0089] The connection method between the second seal 52 and the scraper 20 can refer to the connection method between the first seal 51 and the scraper 20 described above, and will not be repeated here. The two ends of the scraper 20 are open structures. The first seal 51 and the second seal 52 achieve a detachable seal on the openings at both ends of the scraper 20 to prevent sewage in the first sewage chamber 26 and the second sewage chamber 27 from leaking outward through the openings at both ends of the scraper 20.
