Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] In the current cleaning equipment field, products such as robotic vacuum cleaners are widely used. Their core cleaning function mainly relies on cleaning components on the cleaning mechanism, such as roller brushes or tracked mops. These cleaning components effectively remove common debris such as dust and crumbs through friction with the ground, thereby achieving basic floor cleaning.

[0003] However, in actual use cases, due to limitations in the structural design, material properties, and operating methods of the cleaning components, the cleaning equipment performs poorly when dealing with mixed solid and liquid waste (such as wet instant noodles, rice porridge, and a mixture of milk and bread crumbs), making it difficult to meet people's needs for efficient and thorough cleaning. Utility Model Content

[0004] This utility model provides a cleaning device to solve the technical problem that cleaning devices have poor cleaning effect when dealing with solid-liquid mixed waste.

[0005] This utility model provides a cleaning device, which includes a body, a lifting mechanism, a cleaning mechanism, and a suction pipe. The lifting mechanism is connected to the body; the cleaning mechanism is connected to the lifting mechanism and moves up and down between a lowering position and a raising position under the drive of the lifting mechanism; the cleaning mechanism includes a cleaning component, which contacts the surface to be cleaned in the lowering position and is lifted away from the surface to be cleaned in the raising position; one end of the suction pipe is provided with a suction port, which is located behind the cleaning component in the cleaning direction and is fixed to the cleaning mechanism; the other end of the suction pipe is fixed to the body; the suction pipe is configured to suck up dirt from the surface to be cleaned through the suction port; wherein, the suction pipe includes a telescopic section, the telescopic direction of which is consistent with the lifting direction of the cleaning mechanism, or the telescopic direction of which has a directional component in the lifting direction of the cleaning mechanism; when the cleaning mechanism is in the lowering position, the telescopic section extends, and when the cleaning mechanism is in the raising position, the telescopic section retracts.

[0006] The beneficial effects of this design are as follows: By incorporating a suction pipe, the suction port can effectively remove dirt from the surface to be cleaned, especially mixed solid-liquid debris such as wet instant noodles, rice porridge, or a mixture of milk and breadcrumbs—dirt that is difficult to remove using conventional cleaning mechanisms like roller or conveyor belt systems. This not only improves the cleaning effect of the equipment when dealing with mixed solid-liquid debris, thus enhancing its cleaning efficiency, but also prevents residual dirt from spreading and contaminating already cleaned areas, thereby increasing the thoroughness of the cleaning. Furthermore, because the suction pipe can promptly remove dirt, it reduces the number of repeated cleaning operations, thereby improving cleaning efficiency.

[0007] Furthermore, because the suction pipe is equipped with a telescopic section, and the extension and retraction direction of this section is consistent with the lifting and lowering direction of the cleaning mechanism, or has a directional component in the lifting and lowering direction of the cleaning mechanism, the telescopic section can extend or retract accordingly during the lifting and lowering process of the cleaning mechanism. This ensures that the suction pipe will not experience loosening, twisting, or interference due to insufficient or excessive length when the cleaning mechanism is at different heights, thus ensuring the stability and reliability of the cleaning equipment. At the same time, the existence of the telescopic section allows the cleaning mechanism to move freely within a large lifting and lowering range, without concern about the length limitation of the suction pipe. This optimizes the range of motion of the cleaning mechanism, improves the flexibility and adaptability of the cleaning equipment, and enables it to better meet cleaning needs at different heights and locations.

[0008] In one embodiment of the present invention, the suction pipe includes a bent pipe section and a vertical pipe section. The vertical pipe section is connected to the suction port through the bent pipe section. The end of the vertical pipe section away from the bent pipe section is connected to the machine body. At least a portion of the vertical pipe section is a telescopic pipe section.

[0009] The beneficial effects of this design are as follows: At least a portion of the vertical pipe section is designed as a telescopic pipe section, allowing the telescopic pipe section to extend in the same direction as the cleaning mechanism's lifting and lowering. This design, on the one hand, ensures that the travel of the telescopic pipe section matches the lifting and lowering travel of the cleaning mechanism more precisely. This simplifies the design calculation process and allows on-site operators to intuitively adjust the length of the telescopic pipe section without complex operating procedures, significantly improving operational convenience. On the other hand, this unidirectional design ensures that the telescopic pipe section only changes in height during extension and retraction, without dynamic changes in bending angle. Therefore, it effectively reduces wear and deformation of the telescopic pipe section during long-term operation, thereby extending its service life.

[0010] In one embodiment of the present invention, the telescopic pipe segment includes multiple ring units, which are connected end to end in sequence along the telescopic direction of the telescopic pipe segment. Adjacent ring units can be unfolded or stacked to realize the extension and retraction of the telescopic pipe segment.

[0011] The advantages of this design are as follows: The expansion or stacking of adjacent ring units allows for the extension or retraction of the telescopic pipe section. This structure achieves a large compression ratio, which helps reduce the installation space occupied by the suction pipe when not in operation, thus contributing to the compact design of the cleaning equipment. Furthermore, the telescopic pipe section has a simple structural design, facilitating production using mature manufacturing processes. Moreover, the connection method between the ring units facilitates sealing and molding, thereby better ensuring the sealing performance of the telescopic pipe section during use.

[0012] In one embodiment of the present invention, the telescopic pipe segment includes a plurality of pipe body units that are sequentially nested together. Adjacent pipe body units can slide relative to each other along the telescopic direction of the telescopic pipe segment to achieve the extension and retraction of the telescopic pipe segment.

[0013] The beneficial effects of this design are as follows: The extension and retraction of the telescopic pipe section can be achieved through the mutual sliding between adjacent pipe units along the expansion and contraction direction. Because the adjacent pipe units employ a nested structure, the telescopic pipe section is less prone to large lateral displacement during expansion and contraction. Therefore, the lateral cross-sectional area of ​​the telescopic pipe section remains stable, resulting in high connection strength and rigidity. This structural design also enhances the pressure resistance of the telescopic pipe section.

[0014] In one embodiment of the present invention, the cleaning equipment further includes a sludge collection box and a negative pressure generating device. Both the sludge collection box and the negative pressure generating device are installed on the machine body. The negative pressure generating device, the sludge collection box, and the suction pipe are connected in sequence to form a suction passage. When the negative pressure generating device is running, a negative pressure is generated in the suction passage to draw the dirt at the suction port into the sludge collection box.

[0015] The beneficial effects of this design are as follows: When the negative pressure generator is running, a stable negative pressure environment can be created in the suction pipe, collection tank, and connecting path, thereby directly sucking up dirt from the suction port and transporting it to the collection tank. This active suction method can effectively improve the efficiency of dirt recovery, and is especially suitable for scenarios where it is difficult to clean, such as crevices and debris. At the same time, the negative pressure generator can form a closed-loop suction path with the collection tank and suction pipe. Therefore, this design can optimize the airflow path and reduce energy loss while meeting cleaning performance requirements.

[0016] In one embodiment of the present invention, the cleaning mechanism further includes: a bracket and a support assembly. The bracket is connected to a lifting mechanism and has a receiving cavity. The receiving cavity has an opening facing the surface to be cleaned. The support assembly is rotatably installed in the receiving cavity. A cleaning component is wound around the outer periphery of the support assembly. The cleaning component is a mop. The suction port is fixedly connected to the bracket and communicates with the receiving cavity. A scraper is provided on the side facing the opening. A suction port communicating with the suction port is formed between the scraper and the cleaning component.

[0017] The beneficial effects of this design are as follows: Since the suction port is connected to the receiving cavity, a closed or semi-closed suction space is formed at the suction port. This design enhances the suction force between the suction port and the surface to be cleaned, thereby improving the suction efficiency of the suction pipe. Furthermore, the presence of a scraper at the suction port, with a suction inlet formed between the scraper and the cleaning component, further reduces airflow diffusion at the suction location, increasing suction force and thus improving the suction efficiency of the suction pipe. Additionally, as the cleaning component moves across the surface, the scraper collects residual dirt at the suction inlet, facilitating its extraction and further enhancing the efficiency of dirt removal.

[0018] In one embodiment of the present invention, the cleaning mechanism further includes a squeegee connected to the bracket. The squeegee overlaps with the edge of the suction port on the side away from the surface to be cleaned and at least partially contacts the cleaning component. During the rotation of the cleaning mechanism, the squeegee can scrape off the sewage on the cleaning component and guide the sewage into the suction port so that the sewage can be sucked out through the suction port.

[0019] The advantages of this design are as follows: During the rotation of the cleaning mechanism, the squeegee removes wastewater from the cleaning components and directs it to the suction port, where it is then pumped out. Therefore, the collection and discharge of wastewater removed from the cleaning components can be achieved through the suction action of the suction pipe, eliminating the need for an additional wastewater collection device. This design simplifies the overall structure of the cleaning equipment and reduces production costs.

[0020] In one embodiment of the present invention, the cleaning equipment further includes a water replenishment mechanism installed on the bracket. The water outlet of the water replenishment mechanism is connected to the cleaning component to replenish the cleaning component with clean water during the cleaning operation. Along the rotation direction of the cleaning component, the water replenishment mechanism is located on the side of the squeegee away from the suction port.

[0021] The beneficial effects of this design are as follows: By incorporating a water replenishment mechanism, clean water is continuously supplied to the cleaning components, enabling real-time self-cleaning and ensuring relative cleanliness, thus improving cleaning effectiveness. Simultaneously, the suction pipe collects and discharges wastewater scraped from the cleaning components. The two mechanisms work together to form a highly efficient cleaning and wastewater collection system: the water replenishment mechanism provides clean water to the cleaning components for efficient stain removal; the suction pipe collects and discharges wastewater, ensuring an efficient and environmentally friendly cleaning process.

[0022] In one embodiment of the present invention, the cleaning device further includes a shield, which is rotatably mounted on the bracket and disposed on the outer periphery of the receiving cavity. The shield has a first rotation position and a second rotation position. In the first rotation position, the shield closes the suction inlet to block the communication between the suction port and the surface to be cleaned. In the second rotation position, the shield opens the suction inlet to allow the suction port to communicate with the surface to be cleaned.

[0023] The beneficial effects of this design are as follows: By installing a shield, the suction inlet can be opened or closed by rotating the shield. When the suction pipe stops operating, the shield can close the suction inlet. This effectively prevents dirt and grime trapped in the suction pipe from being discharged from the suction inlet during the cleaning equipment's movement, even during vibrations or bumps, thus avoiding secondary contamination of the cleaned area.

[0024] In one embodiment of the present invention, the lifting mechanism includes a driving component, a transmission mechanism, and a linkage mechanism. The cleaning mechanism is connected to the machine body through the linkage mechanism. The driving component drives the transmission mechanism to operate, and the transmission mechanism drives the cleaning mechanism to lift and lower through the linkage mechanism.

[0025] The advantages of this design are: the linkage mechanism can achieve complex motion conversions within a limited space, making it easier to convert the rotational motion of the first output end into the lifting motion of the cleaning mechanism. This facilitates a more compact overall design for the lifting mechanism, making it particularly suitable for cleaning equipment in space-constrained environments. Furthermore, the linkage mechanism can be flexibly arranged according to specific structural requirements, making it easier to install in multiple directions such as horizontal, vertical, or inclined, thus better adapting to different installation spaces and motion conversion requirements. In addition, the main components of the linkage mechanism (such as connecting rods and spherical bearings) are easy to replace and maintain. Compared to hydraulic or electric lifting methods, the linkage mechanism experiences less wear and tear, and the maintenance process is simpler.

[0026] In one embodiment of the present invention, both the linkage mechanism and the transmission mechanism are located on the outer side of the cleaning mechanism along its length, and along the length of the cleaning mechanism, the projection area of ​​at least one of the linkage mechanism and the transmission mechanism partially overlaps with the projection area of ​​the cleaning mechanism.

[0027] The advantages of this design are as follows: By placing the linkage and transmission mechanisms on the outer side of the cleaning mechanism along its length, rather than directly above it, the space occupied above the cleaning mechanism is effectively reduced, lowering the overall height of the cleaning equipment. This allows the equipment to better adapt to height-restricted cleaning scenarios, such as cleaning work in narrow passages or low spaces. Simultaneously, placing the linkage and transmission mechanisms on the outer side of the cleaning mechanism helps maintain the equipment's center of gravity balance, reducing swaying or instability caused by a shift in the center of gravity during cleaning operations, thus improving the stability of the cleaning equipment's operation.

[0028] In one embodiment of this utility model, two sets of linkage mechanisms are provided, and the two sets of linkage mechanisms are respectively arranged on both sides of the outer side of the cleaning mechanism along its length direction; the two sets of linkage mechanisms are connected by a synchronization mechanism, and when the transmission mechanism is running, the synchronization mechanism can realize the synchronous operation of the two sets of linkage mechanisms.

[0029] The beneficial effects of this design are as follows: By arranging two sets of linkage mechanisms on the outer sides of the cleaning mechanism along its length, a dual-sided synchronous drive structure can be formed. This structure allows the lifting and lowering motion of the cleaning mechanism to be completed jointly by the linkage mechanisms on both sides, thereby achieving a uniform distribution of force during lifting and lowering. Compared with a single-sided drive scheme, the dual-sided synchronous drive structure can effectively avoid the risk of uneven load distribution and prevent problems such as swaying or movement jamming caused by uneven force distribution, thus improving the smoothness and accuracy of the lifting and lowering operation of the cleaning mechanism. In addition, since the dual-sided synchronous drive structure can form a dual-sided support structure on both sides of the cleaning mechanism along its length, it can enhance the overall rigidity and load-bearing capacity of the cleaning mechanism. This not only helps to enhance the cleaning mechanism's ability to withstand the loads and impacts generated during cleaning operations, but also effectively extends the service life of the cleaning equipment.

Detailed Implementation

[0073] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0074] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0075] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0076] Please see Figures 1 to 39 This utility model provides a cleaning device 100. The cleaning device 100 has a suction pipe 171 installed behind the cleaning component 131 in the cleaning direction. The suction pipe 171 can suck up the dirt remaining on the surface 190 to be cleaned after the cleaning operation of the cleaning component 131, thereby reducing the dirt residue on the surface 190 to be cleaned and improving the overall cleaning effect of the cleaning device 100.

[0077] The cleaning device 100 provided in the embodiments of this utility model can be a self-moving cleaning robot or a handheld floor scrubber. The self-moving cleaning robot can be a mopping robot or a sweeping and mopping robot, etc. In the following embodiments, some components of the cleaning device 100 are described as an example of a self-moving cleaning robot.

[0078] Please see Figure 1 and Figure 2 The cleaning equipment 100 includes: a body 110, a lifting mechanism 120, a cleaning mechanism 130, and a suction pipe 171.

[0079] The interior of the body 110 can accommodate various components of the cleaning equipment 100. The body 110 can be any shape, such as cylindrical, oval, or D-shaped.

[0080] The cleaning equipment 100 also includes a walking system conventionally provided on existing cleaning equipment 100, used to drive the machine body 110 to move independently, thereby achieving a self-moving walking function on the surface to be cleaned. The walking system includes at least a driver and drive wheels, which are driven to rotate under the action of the driver. There are generally two drive wheels, symmetrically arranged at the bottom of the machine body 110. The specific structure of the walking system and the connection structure between the walking system and the machine body 110 can be referred to the relevant structural descriptions in existing cleaning equipment 100, and will not be repeated here.

[0081] The specific structure of the cleaning mechanism 130 is not limited; for example, it can be a disc-shaped mop structure, a roller-shaped mop structure, a conveyor belt mop structure, etc., as long as it can meet the cleaning requirements of the surface 190 to be cleaned. The cleaning mechanism 130 includes a cleaning component 131, which is used to clean the surface 190 to be cleaned. The cleaning component 131 can be configured for dry mopping or wet mopping; this embodiment does not limit this.

[0082] The lifting mechanism 120 is connected to the machine body 110, and the cleaning mechanism 130 is connected to the lifting mechanism 120. Driven by the lifting mechanism 120, the cleaning mechanism 130 moves up and down relative to the machine body 110. It should be noted that the cleaning mechanism 130 has at least a raised position and a lowered position during its lifting operation. When in the raised position, the cleaning mechanism 130 lifts away from the surface to be cleaned 190, and the cleaning component 131 also lifts away from the surface to be cleaned 190, thereby stopping the cleaning operation on the surface to be cleaned 190. When in the lowered position, the cleaning mechanism 130 approaches the surface to be cleaned 190, allowing the cleaning component 131 to contact the surface to be cleaned 190, thus completing the cleaning operation on the surface to be cleaned 190. In this embodiment, the type and structure of the lifting mechanism 120 are not limited, including but not limited to linkage mechanisms, actuators, and pulley lifting assemblies.

[0083] Optionally, in one embodiment, the cleaning device 100 may further include a side brush and a roller brush, both located at the bottom of the body 110. Along the traveling direction of the body 110, both the side brush and the roller brush are positioned in front of the cleaning mechanism 130. The side brush may be located at the edge of the body 110 and can rotate via a rotating mechanism, which may be a combination of a motor and a reducer. When the side brush rotates, it gathers debris from the edge of the body 110 towards the inside of the body 110, thereby increasing the cleaning range of the cleaning device 100. The side brush may be a rubber strip or a bristle brush, as long as it can clean the ground; there are no limitations. The roller brush is rotatably disposed within a roller brush cavity at the bottom of the body 110. During its rotation, the roller brush can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; there are no limitations in this embodiment.

[0084] Along the traveling direction of the machine body 110, the side brush and roller brush are positioned in front of the cleaning mechanism 130. This facilitates the cleaning operation of the cleaning equipment 100, which involves dry sweeping followed by wet mopping. This improves the cleaning effect and efficiency, and also facilitates the layout of the internal space of the machine body 110.

[0085] In addition, the cleaning equipment 100 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 fuselage 110, a buffer and vision sensor located at the front of the fuselage 110, and an edge sensor located on the front side wall of the fuselage 110. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the fuselage 110 and the obstacle. The control system controls the cleaning equipment 100 to perform corresponding actions based on this distance. For example, it controls the cleaning equipment 100 to perform obstacle avoidance, edge cleaning, and return to the base station.

[0086] Please see Figure 2 , Figure 3 and Figure 6 A suction pipe 171 is disposed between the cleaning mechanism 130 and the machine body 110. One end of the suction pipe 171 along its length is fixedly connected to the cleaning mechanism 130 and is provided with a suction port 1711. The suction port 1711 is located in the cleaning direction of the cleaning component 131 (e.g., ...). Figure 6 Behind the center M-axis direction, at least a portion of the suction port 1711 is in communication with the surface to be cleaned 190.

[0087] The cleaning direction of cleaning component 131 refers to the direction of movement of cleaning component 131 relative to the surface 190 to be cleaned during cleaning operation by the cleaning mechanism 130 (such as a tracked wiping structure or a roller wiping structure). For tracked wiping structures or roller wiping structures, the cleaning direction is parallel to the forward direction of the cleaning equipment 100. Specifically, the cleaning direction of cleaning component 131 can be the same as or opposite to the forward direction of the cleaning equipment 100. For example, in this embodiment, such as... Figure 6 As shown, the cleaning mechanism 130 is a roller-type cleaning cloth structure, and the cleaning direction of the cleaning component 131 is the same as the forward direction of the cleaning equipment 100. The other end of the suction pipe 171 is fixedly connected to the machine body 110 along its length. It should be noted that the suction pipe 171 can be directly fixed to the machine body 110, or it can be indirectly fixed to the machine body 110 by connecting to other components fixed to the machine body 110. The method of fixing the suction pipe 171 to the machine body 110 and to the cleaning mechanism 130 is not limited; for example, it can be a bolted connection, a plug-in connection, a flange connection, etc.

[0088] The suction pipe 171 is configured to suck up dirt from the surface 190 to be cleaned through the suction port 1711. In this embodiment, the dirt on the surface 190 to be cleaned can be conventional solid waste, such as paper scraps, animal hair, bread crumbs, fruit peels, etc., which can be cleaned by conventional cleaning mechanisms 130 such as roller wiping structures or conveyor belt wiping structures. It can also be solid-liquid mixed waste on the surface 190 to be cleaned, such as wet instant noodles, rice porridge, milk and bread crumbs mixtures, etc., which are difficult to clean by conventional cleaning mechanisms 130 such as roller wiping structures or conveyor belt wiping structures. The way the suction pipe 171 generates suction force at the suction port 1711 is not limited. For example, the suction pipe 171 can generate negative pressure by the action of a vacuum pump (such as a centrifugal pump), thereby generating suction force at the suction port 1711 to suck up the dirt on the surface 190 to be cleaned. The suction pipe 171 can also generate negative pressure by the action of a fan (such as a centrifugal fan), thereby generating suction force at the suction port 1711 to suck up dirt on the surface 190 to be cleaned.

[0089] Please see Figure 3 The suction pipe 171 includes a telescopic section 1712. The telescopic direction of the telescopic section 1712 is consistent with the lifting direction of the cleaning mechanism 130, or the telescopic direction of the telescopic section 1712 has a directional component in the lifting direction of the cleaning mechanism 130. When the cleaning mechanism 130 is in the lowered position, the telescopic section 1712 extends; when the cleaning mechanism 130 is in the raised position, the telescopic section 1712 retracts. It should be noted that the telescopic section 1712 can be a flexible structure, such as a corrugated rubber structure, or a rigid telescopic structure, such as a sleeve-type telescopic structure. It is important to understand that regardless of whether the telescopic section 1712 is a flexible or rigid structure, its design must meet the suction force requirements of the suction pipe 171 under normal operating conditions to ensure the stability of the suction capacity of the suction pipe 171.

[0090] Specifically, in one embodiment, the suction pipe 171 may be at least partially a vertical pipe section, the extension direction of which is consistent with the lifting direction of the cleaning mechanism 130. A telescopic pipe section 1712 is disposed within the vertical pipe section, and the telescopic direction of the telescopic pipe section 1712 is consistent with the lifting direction of the cleaning mechanism 130. When the cleaning mechanism 130 is in the lowered position, the telescopic pipe section 1712 extends along the lifting direction; when the cleaning mechanism 130 is in the raised position, the telescopic pipe section 1712 retracts along the lifting direction. In this embodiment, the telescopic pipe section 1712 may be a sleeve-type telescopic pipe section 1712, a corrugated pipe-type telescopic pipe section 1712, an elastic telescopic pipe section 1712, or other telescopic structures capable of meeting the suction pressure within the suction pipe 171.

[0091] In another embodiment, the suction pipe 171 includes an inclined pipe section, and a telescopic pipe section 1712 is disposed within the inclined pipe section. The telescopic direction of the telescopic pipe section 1712 has a directional component in the lifting direction of the cleaning mechanism 130. When the cleaning mechanism 130 is in the lowered position, the telescopic pipe section 1712 extends, and when the cleaning mechanism 130 is in the raised position, the telescopic pipe section 1712 retracts.

[0092] The telescopic pipe section 1712 has a directional component in the lifting direction of the cleaning mechanism 130, meaning there is a certain angle between the telescopic pipe section 1712's telescopic direction and the cleaning mechanism 130's lifting direction. Therefore, the telescopic pipe section 1712's telescopic direction will have a projection in the lifting direction; this projection is the directional component. Since the inclined pipe section is inclined, the telescopic pipe section 1712's telescopic direction is consistent with the inclined direction of the inclined pipe section, and is also an inclined direction. This means that the telescopic pipe's telescopic movement not only affects the length of the suction pipe 171, but also produces a certain displacement in the vertical direction (i.e., the lifting direction). Specifically, when the telescopic pipe section 1712 extends, it not only increases the length of the inclined pipe section, but also causes the inclined pipe section to move downward a certain distance in the vertical direction to accommodate the lowering action of the cleaning mechanism 130. When the telescopic pipe section 1712 retracts, it not only shortens the length of the inclined pipe section, but also causes the inclined pipe section to move upward a certain distance in the vertical direction to accommodate the lifting action of the cleaning mechanism 130.

[0093] It should be understood that when the telescopic pipe section 1712 is set in an inclined pipe section, the telescopic pipe section 1712 needs to be set as a flexible structure (such as a rubber corrugated pipe or a similar flexible telescopic pipe structure) in order to adapt to the resulting tilt angle and shape changes during the expansion and contraction process.

[0094] By installing a suction pipe 171, the suction port 1711 of the suction pipe 171 can suck up dirt from the surface to be cleaned, especially solid-liquid mixed waste on the surface to be cleaned 190, such as wet instant noodles, rice porridge, and a mixture of milk and bread crumbs, which are difficult to clean by conventional cleaning mechanisms 130 such as roller cloth structures or conveyor cloth structures. This not only improves the cleaning effect of the cleaning equipment 100 when dealing with solid-liquid mixed waste, thereby enhancing the cleaning performance and overall cleaning effect of the cleaning equipment 100, but also prevents dirt from spreading and contaminating the already cleaned area, thus enhancing the thoroughness of the cleaning. At the same time, because the suction pipe 171 can remove dirt in a timely manner, the number of cleaning operations of the cleaning components 131 can be reduced, thereby improving cleaning efficiency.

[0095] Furthermore, because the suction pipe 171 is equipped with a telescopic section 1712, and the extension direction of the telescopic section 1712 is consistent with the lifting direction of the cleaning mechanism 130, or has a directional component in the lifting direction of the cleaning mechanism 130, the telescopic section 1712 can extend or retract accordingly during the lifting and lowering process of the cleaning mechanism 130, thereby maintaining a stable connection between the suction pipe 171 and the cleaning mechanism 130. This ensures that the suction pipe 171 will not experience loosening, twisting, or interference due to insufficient or excessive length when the cleaning mechanism 130 is at different height positions, thus ensuring the stability and reliability of the cleaning equipment 100. Simultaneously, the presence of the telescopic section 1712 allows the cleaning mechanism 130 to move freely within a large lifting range without concern for the length limitation of the suction pipe 171, thereby optimizing the movement range of the cleaning mechanism 130, improving the flexibility and adaptability of the cleaning equipment 100, and enabling it to better meet cleaning needs at different heights and positions. Please refer to [link / reference]. Figure 5 and Figure 8 In one embodiment of this utility model, the suction pipe 171 includes a bent pipe section 1713 and a vertical pipe section 1714. The vertical pipe section 1714 is connected to the suction port 1711 through the bent pipe section 1713, and the end of the vertical pipe section 1714 away from the bent pipe section 1713 is connected to the machine body 110. Specifically, one end of the bent pipe section 1713 is connected to the suction port 1711, and the other end of the bent pipe section 1713 is connected to one end of the vertical pipe section 1714. The other end of the vertical pipe section 1714 is connected to the machine body 110 or other components (such as a sludge collection box) on the machine body 110. The bend shape of the bent pipe section 1713 can be of various forms, such as a right-angle bend structure, an obtuse-angle bend structure, etc., as long as the pipe section has a certain degree of curvature. Since the height of the sludge collection box is usually higher than the height of the suction port 1711, a bent pipe section 1713 is set on the suction pipe section 171. Compared with the overall straight pipe structure, this design can easily adjust the suction direction of the suction pipe 171, and is especially convenient for achieving a reasonable layout and installation of the suction pipe section 171 in a limited installation space.

[0096] At least a portion of the vertical pipe section 1714 is a telescopic pipe section 1712. In one embodiment, the entire vertical pipe section 1714 may be a telescopic pipe section 1712, meaning one end of the telescopic pipe section 1712 is connected to the bent pipe section 1713, and the other end is fixedly connected to the fuselage 110. In another embodiment, only a portion of the vertical pipe section 1714 is a telescopic pipe section 1712. The specific location of the telescopic pipe section 1712 on the vertical pipe section 1714 is not limited; it may be the end of the vertical pipe section 1714 closest to the fuselage 110, the end of the vertical pipe section 1714 closest to the bent pipe section 1713, or even the middle portion of the vertical pipe section 1714.

[0097] In this embodiment, at least a portion of the vertical pipe section 1714 is configured as a telescopic pipe section 1712. This structural design allows the telescopic pipe section 1712 to extend in the same direction as the lifting direction of the cleaning mechanism 130. This design, on the one hand, ensures that the travel of the telescopic pipe section 1712 matches the lifting travel of the cleaning mechanism 130 more precisely, as the extension and retraction directions are aligned. This simplifies the design calculation process and allows on-site operators to intuitively adjust the pipe section length without complex operating procedures, significantly improving operational convenience. On the other hand, this unidirectional design ensures that the telescopic pipe section 1712 only undergoes height changes during extension and retraction, without dynamic changes in bending angle. Therefore, it effectively reduces wear and deformation of the telescopic pipe section 1712 during long-term operation, thereby extending its service life.

[0098] Please see Figure 5 and Figure 8 In one embodiment of this utility model, the telescopic pipe section 1712 includes multiple ring units 17121. These ring units 17121 are connected end-to-end along the telescopic direction of the pipe section 1712. Adjacent ring units 17121 can be unfolded or stacked to achieve the extension and retraction of the telescopic pipe section 1712. The material of the ring units 17121 can be varied, including flexible materials (such as rubber, flexible plastics, etc.) or metal materials with a certain degree of elasticity (such as stainless steel, aluminum alloys, etc.), as long as they meet the pressure resistance requirements of the suction pipe 171. Flexible material ring units 17121 have better flexibility during unfolding and stacking, while metal materials provide higher strength and durability. The specific shape of the ring units 17121 is not limited; for example, they can be designed as circular rings, elliptical rings, or other polygonal ring structures. The specific shape needs to be determined based on the overall structural shape of the suction pipe 171 and the size of the installation space.

[0099] There are several ways to connect adjacent annular units 17121. For example, adjacent annular units 17121 can be connected by flexible connectors (such as rubber rings, flexible plastic strips, etc.) to form a bellows-like telescopic structure. This connection method makes the telescopic tube segment 1712 more flexible during expansion and contraction, and can adapt to complex motion requirements. Annular units 17121 can also be connected by rigid connectors (such as metal hinges, bolts, etc.), forming a rigid telescopic sealed pipe structure in conjunction with an externally fitted airtight flexible cover (such as three-proof fabric, plastic sheeting, etc.). This connection method can improve the structural strength and stability of the telescopic tube segment 1712, making it suitable for use in scenarios requiring high suction pressure.

[0100] In this embodiment, the extension or retraction of the telescopic pipe section 1712 can be achieved by expanding or stacking adjacent annular units 17121. This structure can achieve a large compression ratio, which helps to reduce the installation space occupied by the suction pipe 171 in the non-working state and is also beneficial to the compact design of the cleaning equipment 100. At the same time, the structural design of the telescopic pipe section 1712 is relatively simple, making it easy to produce using mature manufacturing processes. Furthermore, the connection method between the annular units 17121 is easy to achieve sealed molding, thereby better ensuring the sealing performance of the telescopic pipe section 1712 during use.

[0101] Qing Reference Figure 9 and Figure 10 In one embodiment of this utility model, the telescopic tube segment 1712 includes multiple tube body units 17122 sequentially nested together. Adjacent tube body units 17122 can slide relative to each other along the telescopic direction of the telescopic tube segment 1712 to achieve the extension and retraction of the telescopic tube segment 1712. The tube body units 17122 can be made of various materials, including but not limited to metals (such as aluminum alloys and stainless steel), plastics (such as polycarbonate and polyethylene), and composite materials (such as carbon fiber reinforced plastics), etc. The specific material selection is based on meeting the actual design performance requirements. The cross-sectional shape of the tube body unit 17122 is not limited and can be designed as a circular, elliptical, or polygonal cross-section. The sliding connection between adjacent tube body units 17122 can be achieved by setting a reasonable assembly gap, or by additionally setting a sliding structure (such as a sliding bearing) between adjacent tube body units 17122. By adjusting the number and size of the tube body units 17122, this telescopic structure can achieve different telescopic stroke adjustments to adapt to different lifting stroke requirements. It should be noted that, in order to achieve a sealed connection between adjacent tube units 17122, a sealing ring or sealing gasket can be provided between the tube units 17122.

[0102] In this embodiment, the extension and retraction of the telescopic pipe section 1712 can be achieved by the mutual sliding between adjacent pipe units 17122 along the telescopic direction. Because the adjacent pipe units 17122 employ a nested structure, the telescopic pipe section 1712 is less prone to large lateral displacement during telescopic operation. Therefore, the lateral cross-sectional area of ​​the telescopic pipe section 1712 can remain stable, resulting in high connection strength and rigidity. This structural design is also more conducive to improving the pressure resistance of the telescopic pipe section 1712.

[0103] Please see Figure 7In one embodiment of this utility model, the cleaning equipment 100 further includes a sludge collection tank 172 and a negative pressure generating device 173, both of which are disposed on the body 110. The sludge collection tank 172 can be clipped to the body 110 or fixed to the body 110 by bolts. The negative pressure generating device 173 can be integrated into the sludge collection tank 172 or can be disposed separately on the body 110 and connected to the sludge collection tank 172 through a ventilation duct. The negative pressure generating device 173 can be any device capable of generating negative pressure in the sludge collection tank 172, such as a vacuum pump or centrifugal fan.

[0104] The suction pipe 171 connects to the sludge collection box 172. The negative pressure generating device 173, the sludge collection box 172, and the suction pipe 171 are sequentially connected to form a suction passage. When the negative pressure generating device 173 is running, a negative pressure is generated in the suction passage, thereby sucking the dirt at the suction port 1711 into the sludge collection box 172. Specifically, the sludge collection box 172 is provided with an air inlet 1721 and an air outlet 1722. The air outlet 1722 is located on the top wall or side wall of the sludge collection box 172 near the top wall, and the air inlet 1721 is located at a height lower than the air outlet 1722. A waste receiving cavity 1321 is provided between the air outlet 1722 and the air inlet 1721, and the bottom wall of the waste receiving cavity 1321 is lower than the height of the air inlet 1721.

[0105] The exhaust port of the negative pressure generating device 173 is connected to the exhaust port 1722 of the sludge collection box 172, and the end of the suction pipe 171 away from the suction port 1711 is connected to the air inlet 1721 of the sludge collection box 172. When the negative pressure generating device 173 is running, a negative pressure is generated in the sludge collection box 172 and the suction pipe 171, which in turn generates suction at the suction port 1711. Under the action of suction, dirt enters the suction pipe 171 from the suction port 1711 and then passes through the air inlet 1721 of the sludge collection box 172. Since the height of the air inlet 1721 is lower than that of the exhaust port 1722, the dirt will fall into the dirt receiving cavity 1321 under its own gravity, thereby achieving effective collection of dirt.

[0106] In this embodiment, when the negative pressure generating device 173 is running, a stable negative pressure environment can be formed in the suction pipe 171, the collection box 172, and the connecting path. This allows dirt (such as dust, particles, or liquid) at the suction port 1711 to be directly sucked up and transported into the collection box 172. This active suction method can effectively improve the efficiency of dirt recovery, and is especially suitable for scenarios where it is difficult to clean, such as crevices and debris. At the same time, the negative pressure generating device 173 can form a closed-loop suction path with the collection box 172 and the suction pipe 171. Therefore, this design can optimize the airflow path and reduce energy loss while meeting the requirements of cleaning performance.

[0107] Please see Figure 5and Figure 6 In one embodiment of this utility model, the cleaning mechanism 130 further includes a bracket 132 and a support assembly 133. The bracket 132 is connected to the lifting mechanism 120 and has a receiving cavity 1321. The receiving cavity 1321 has an opening 1322 facing the surface to be cleaned 190. The support assembly 133 is rotatably mounted in the receiving cavity 1321. The cleaning element 131 is a mop, which is wound around the outer periphery of the support assembly 133. The support assembly 133 can adopt various forms such as a roller structure or a tracked structure. The suction port 1711 is fixedly connected to the bracket 132 and is located behind the support assembly 133 (i.e., behind the cleaning direction of the cleaning element 131) and communicates with the receiving cavity 1321. The suction port 1711 is disposed facing the cleaning element 131 and at least partially facing the opening 1322 to communicate with the surface to be cleaned 190. Please refer to [link to relevant documentation]. Figure 6 The suction port 1711 has a scraper 160 on the side wall facing the opening 1322. A suction port 17111 is formed between the scraper 160 and the cleaning component 131, connecting the surface to be cleaned 190 and the suction port 1711. It should be noted that when the cleaning device 100 is in the lowered position, the scraper 160 can abut against the surface to be cleaned 190. The material of the scraper 160 in this embodiment is not limited; for example, it can be any flexible material such as rubber or silicone.

[0108] In this embodiment, since the suction port 1711 is connected to the receiving cavity 1321, a closed or semi-closed suction space can be formed at the suction port 1711. This design helps to enhance the suction force between the suction port 1711 and the surface to be cleaned 190, thereby improving the suction efficiency of the suction pipe 171. In addition, since a scraper 160 is provided at the suction port 1711, and a suction inlet 17111 is formed between the scraper 160 and the cleaning component 131, on the one hand, the design of the suction inlet 17111 helps to reduce the diffusion of the suction airflow at the suction position, further improving the suction force at the suction inlet 17111, thereby further improving the suction efficiency of the suction pipe 171. On the other hand, when the cleaning component 131 moves on the surface to be cleaned 190, the scraper 160 can also collect dirt at the suction inlet 17111, thereby facilitating the suction of dirt into the suction port 1711.

[0109] Please see Figure 5 and Figure 6 In one embodiment of this utility model, the cleaning mechanism 130 further includes a squeegee 134 connected to the bracket 132. The squeegee 134 overlaps with the edge of the suction port 1711 on the side opposite to the surface 190 to be cleaned, and at least partially contacts the cleaning component 131. Exemplarily, in this embodiment, the cleaning mechanism 130 can be a roller wiping cloth structure. In other embodiments, the cleaning mechanism 130 can also be a tracked wiping cloth structure.

[0110] During the rotation of the cleaning mechanism 130, the scraper 134 can scrape off the wastewater on the cleaning component 131 and guide the wastewater into the suction port 1711, so that the wastewater can be sucked out through the suction port 1711. The specific structure of the scraper 134 is not limited. For example, it can be a single scraper structure, a comb structure, or a combination of scraper and comb structure, etc., as long as it can scrape off the wastewater on the cleaning component 131 during the rotation of the cleaning component 131. The wastewater on the cleaning component 131 can be the wastewater absorbed by the dry cleaning component when it passes the surface to be cleaned 190, or the wastewater formed after the cleaning component 131 replenishes clean water for cleaning operations. This embodiment is not limited to either.

[0111] Specifically, along the height direction of the cleaning mechanism 130 (e.g. Figure 6 (As indicated by the arrow H in the middle), the squeegee 134 is positioned on the side of the suction port 1711 away from the surface 190 to be cleaned, that is, the position where the squeegee 134 contacts the cleaning component 131 is above the suction port 1711. Along the rotation direction of the cleaning component 131 (e.g., ... Figure 6 (As shown in the S-direction), the cleaning component 131 passes sequentially through the surface to be cleaned 190, the suction port 1711, and the squeegee 134. When the cleaning component 131 passes the squeegee 134, the squeegee 134 contacts the cleaning component 131, scraping off the wastewater adhering to the cleaning component 131. The scraped wastewater falls into the suction port 1711 under its own gravity and is then sucked away by the suction force generated by the suction pipe 171.

[0112] In this embodiment, during the rotation of the cleaning mechanism 130, the scraper 134 can scrape off the sewage on the cleaning component 131 and guide the sewage into the suction port 1711, so that the sewage can be sucked out through the suction port 1711. Therefore, the collection and discharge of sewage scraped off the cleaning component 131 can be achieved through the suction action of the suction pipe 171, eliminating the need for an additional sewage collection device. This design simplifies the overall design structure of the cleaning equipment 100 and reduces production costs.

[0113] Please see Figure 6 In one embodiment of this utility model, the cleaning device 100 further includes a water replenishment mechanism. The water outlet of the water replenishment mechanism is connected to the cleaning component 131 for replenishing the cleaning component 131 with clean water during the cleaning operation. Along the height direction of the cleaning mechanism 130, the water outlet of the water replenishment mechanism is located on the side of the scraper 134 away from the suction port 1711.

[0114] Specifically, the water replenishment mechanism may include a clean water tank and a clean water delivery pipeline 183. The clean water tank is installed on the machine body 110, and the clean water delivery pipeline 183 connects the outlet of the clean water tank and the cleaning component 131. The clean water delivery pipeline 183 is at least partially located inside the bracket 132 and is connected to the cleaning component 131 for spraying clean water onto the cleaning component 131 to achieve clean water replenishment. The outlet of the clean water delivery pipeline 183 is located on the side of the scraper 134 away from the suction port 1711. In this way, the clean water delivery pipeline 183 can replenish clean water to the cleaning component 131 after the scraper 134 has removed the sewage, thereby achieving a better clean water replenishment effect, avoiding contamination of the clean water by the sewage on the cleaning component 131, and ensuring that the cleaning component 131 always maintains a good cleaning effect.

[0115] In this embodiment, a water replenishment mechanism continuously supplies clean water to the cleaning component 131, keeping it moist and thus better adsorbing and removing stubborn stains, reducing cleaning frequency and time, and improving cleaning efficiency. Simultaneously, the suction pipe 171 collects and discharges wastewater scraped from the cleaning component 131. The two mechanisms work together to form a highly efficient cleaning and wastewater collection system: the water replenishment mechanism provides clean water to the cleaning component 131, improving its stain removal effect; the suction pipe 171 collects and discharges wastewater, ensuring an efficient and environmentally friendly cleaning process.

[0116] Please see Figure 6 and Figure 11 In one embodiment of this utility model, the cleaning device 100 further includes a shielding member 140, which is rotatably mounted on the bracket 132 and disposed on the outer periphery of the receiving cavity 1321. The shielding member 140 has a first rotating position and a second rotating position. Please refer to [link to relevant documentation]. Figure 11 and Figure 12 In the first rotated position, the shield 140 closes the suction inlet 17111 to block the communication between the suction inlet 1711 and the surface to be cleaned 190. (See also...) Figure 6 In the second rotation position, the shield 140 opens the suction port 17111 to allow the suction port 1711 to communicate with the surface to be cleaned 190, thereby enabling the normal suction action of the suction port 1711.

[0117] In this embodiment, a shielding member 140 is provided, and the suction inlet 17111 can be opened or closed by rotating the shielding member 140. When the suction pipe 171 stops operating, the shielding member 140 can close the suction inlet 17111. In this way, even if vibration or bumps occur during the movement of the cleaning equipment 100, it can effectively prevent dirt retained in the suction pipe 171 from being discharged from the suction inlet 17111, avoiding secondary pollution to the cleaning area.

[0118] Please see Figure 11 and Figure 12 In one embodiment of this utility model, when the blocking member 140 is in the first rotation position, the blocking member 140 can not only close the suction inlet 17111, but also close the opening 1322 of the receiving cavity 1321, so as to seal the cleaning member 131 inside the receiving cavity 1321. Please refer to Figure 6 When the shield 140 is in the second rotation position, in addition to opening the suction inlet 17111, the shield 140 can also open the opening 1322 of the receiving cavity 1321, exposing the cleaning component 131 to the opening 1322. In this way, when the cleaning mechanism 130 is in the lowered position, the cleaning component 131 can contact the surface to be cleaned 190 and perform routine cleaning operations.

[0119] The cleaning component 131 is prone to carrying dirt during the cleaning process. When the cleaning mechanism 130 passes over the carpet, even if the cleaning component 131 is lifted by the lifting mechanism 120, the long-pile carpet may still cause the cleaning component 131 to come into contact with the carpet; in addition, if the cleaning component 131 is used for wet cleaning, wastewater may still drip onto the carpet after being lifted. In both of these cases, simply lifting the cleaning component 131 in the vertical direction is not enough to effectively prevent the carpet from becoming contaminated.

[0120] In this embodiment, by providing a shielding member 140, when the shielding member 140 is in the first rotation position, it can close the opening 1322, sealing the cleaning member 131 within the receiving cavity 1321, thereby enhancing the isolation effect between the cleaning member 131 and the surface to be cleaned 190. This further reduces the probability of dust, stains, or water stains on the cleaning member 131 dripping onto the surface to be cleaned 190, thus effectively reducing the contamination of the carpet by the cleaning member 131. When the shielding member 140 is in the second rotation position, it can open the opening 1322, allowing the cleaning member 131 to be fully exposed and in contact with the surface to be cleaned 190. This ensures that the shielding member 140 does not interfere with the normal operation of the cleaning member, thereby effectively guaranteeing cleaning efficiency and quality.

[0121] The following embodiments provide a detailed description of the structure of the lifting mechanism 120 and the blocking member 140, as well as the connection relationship between the lifting mechanism 120 and the blocking member 140.

[0122] Please see Figure 6 The shielding member 140 is rotatably mounted on the cleaning mechanism 130 and partially shields the outer periphery of the cleaning member 131. There are various rotatable mounting methods; for example, the shielding member 140 can be directly rotatably connected to the cleaning mechanism 130 via a rotating shaft, or it can be indirectly rotatably connected to the cleaning mechanism 130 via other transmission components (gear assembly, worm gear assembly). The shielding member 140 has a first rotating position and a second rotating position.

[0123] like Figure 11As shown, in the first rotation position, the shield 140 is along the height direction of the cleaning mechanism 130 (e.g., Figure 7 (As shown in the Z-axis direction) is located between the surface to be cleaned 190 and the cleaning component 131 to isolate the cleaning component 131 from the surface to be cleaned 190. For example... Figure 17 As shown, in the second rotation position, the shield 140 rotates away from the position between the surface to be cleaned 190 and the cleaning member 131, so that the cleaning member 131 can contact the surface to be cleaned 190 along the height direction of the cleaning device 100.

[0124] Please see Figure 19 and Figure 21 The lifting mechanism 120 includes a drive component 121 and a transmission mechanism 122. The transmission mechanism 122 includes a power input end 123 and two power output ends. The drive component 121 drives the two power output ends through the power input end 123. The drive component 121 can be any device capable of generating power, such as a motor, a combination of a motor and a reducer, or a hydraulic motor. Specifically, the power input end 123 is connected to the output end of the drive component 121 to receive power from the drive component 121 and transmit the power to the two power output ends. The connection method between the power input end 123 and the output end of the drive component 121 is not limited; for example, it can be a direct connection or an indirect connection through common transmission mechanisms such as chain drive, belt drive, or gear drive. One of the two power output ends is connected to the cleaning mechanism 130 and transmits power to the cleaning mechanism 130 to drive the cleaning mechanism 130 to move up and down between the raised and lowered positions. The other of the two power output terminals is connected to the shield 140 and transmits power to the shield 140 to drive the shield 140 to rotate between the first rotation position and the second rotation position.

[0125] In this embodiment, the cleaning device 100 is provided with a lifting mechanism 120, which can drive the cleaning mechanism 130 to move up and down. By controlling the lifting and lowering of the cleaning mechanism 130, the cleaning component 131 can remain separated from the surface to be cleaned 190 in the height direction of the cleaning device 100. When the cleaning device 100 passes over the carpet, this separation can achieve physical isolation between the cleaning component 131 and the carpet, thereby reducing the probability of the cleaning component 131 coming into contact with the carpet, and thus reducing the possibility of stains or moisture on the cleaning component 131 contaminating the carpet. In addition, the cleaning device 100 is also provided with a rotatable blocking component 140. The blocking component 140 can switch between a first rotation position and a second rotation position, thereby achieving isolation or contact between the cleaning component 131 and the surface to be cleaned 190. When the cleaning device 100 passes over the carpet, the blocking component 140 can be rotated to the first rotation position. At this time, the shielding member 140 is located between the carpet and the cleaning member 131, which can further block the contact path between the cleaning member 131 and the carpet, thereby further reducing the probability that stains or moisture on the cleaning member 131 will contaminate the carpet.

[0126] Furthermore, this embodiment reduces the number of drive components 121 used by sharing a single drive component 121 to drive the lifting and lowering of the cleaning mechanism 130 and the rotation of the shielding component 140. This design not only reduces the manufacturing cost of the cleaning equipment 100 but also saves installation space in the body 110, facilitating a compact structural design for the cleaning equipment 100. Meanwhile, in the design of the cleaning mechanism 130, the coverage area of ​​the cleaning surface needs to be fully considered, therefore the cleaning mechanism 130 typically requires a large extension dimension in the width direction. At the same time, the drive component 121 used for lifting and lowering generally needs to be arranged along the height direction of the cleaning mechanism 130. If too many drive components 121 are used, too much height space in the cleaning mechanism 130 will be occupied, resulting in a significant reduction in the height space of the body 110 of the cleaning equipment 100. Therefore, adopting the scheme of sharing a single drive component 121 in this embodiment facilitates a compact structural design of the cleaning equipment 100 in terms of height space, making it easier for the cleaning equipment 100 to perform cleaning operations in height-restricted scenarios. Meanwhile, since the lifting of the cleaning mechanism 130 and the rotation of the shielding member 140 are controlled by the same drive member 121, their actions can be better coordinated, which helps to simplify the control logic and improve the reliability and coordination of the control system.

[0127] In one embodiment of this utility model, please refer to Figure 11 When the cleaning mechanism 130 is in the raised position, the blocking member 140 rotates to the first rotation position. At this time, the cleaning member 131 is lifted away from the surface to be cleaned 190, the cleaning operation stops, and the blocking member 140 is positioned between the surface to be cleaned 190 and the cleaning member 131, isolating the cleaning member 131 from the surface to be cleaned 190. Please refer to [link / reference]. Figure 17When the cleaning mechanism 130 is in the lowered position, the shielding member 140 rotates to the second rotation position. At this time, the cleaning member 131 contacts the surface to be cleaned 190 to perform the cleaning operation, and the shielding member 140 moves away from the position between the surface to be cleaned 190 and the cleaning member 131, so that the cleaning member 131 can fully contact the surface to be cleaned 190.

[0128] This configuration allows for coordinated control of the lifting and lowering movement of the cleaning mechanism 130 and the rotation of the blocking component 140, thereby ensuring greater efficiency and reliability of the cleaning operation. Simultaneously, when the cleaning component 131 is lifted away from the surface 190 to be cleaned, the blocking component 140 can promptly isolate the cleaning component 131 from the surface 190, preventing dust, stains, or other contaminants on the cleaning component 131 from falling onto the surface 190, thus effectively reducing the risk of contamination to the carpet or the surface 190 to be cleaned.

[0129] In one embodiment, the lifting and lowering movement of the cleaning mechanism 130 and the rotation of the shielding member 140 can be completely synchronized. Specifically, when the cleaning mechanism 130 starts to lift and lower, the shielding member 140 rotates synchronously; when the cleaning mechanism 130 stops lifting and lowering, the shielding member 140 stops rotating synchronously.

[0130] In another embodiment, the lifting and lowering of the cleaning mechanism 130 and the rotation of the shielding member 140 may operate synchronously for part of a time period and asynchronously for part of a time period. For example, in the initial stage of the operation of the drive member 121, the rotation of the shielding member 140 may precede the lifting and lowering of the cleaning mechanism 130, and in the subsequent time period, the rotation of the shielding member 140 will be synchronized with the lifting and lowering of the cleaning mechanism 130.

[0131] Please participate Figure 21 and Figure 22 In one embodiment of this utility model, the two power output terminals are a first power output terminal 124 and a second power output terminal 125, respectively. The first power output terminal 124 drives the cleaning mechanism 130 to rise and fall, and the second power output terminal 125 drives the shielding member 140 to rotate. The power input terminal 123 drives the first power output terminal 124 to operate, and the first power output terminal 124 drives the second power output terminal 125 to operate.

[0132] In this embodiment, since the power input terminal 123 drives the first power output terminal 124, and the first power output terminal 124 drives the second power output terminal 125, a hierarchical power transmission can be achieved. Using this hierarchical transmission method, firstly, the arrangement of the first power output terminal 124 and the second power output terminal 125 can be flexibly adjusted according to actual needs, which is beneficial for optimizing the overall layout of the cleaning equipment 100 and improving space utilization; secondly, the single power transmission path avoids energy loss caused by branch structures, making power transmission more stable and efficient; finally, the hierarchical transmission mechanism eliminates the need for complex power distribution coordination, reducing the control difficulty of the system and improving the reliability of the cleaning equipment 100's operation.

[0133] In this invention, the specific structural forms of the power input end 123, the first power output end 124, and the second power output end 125 are not limited. For example, they can be a shaft structure, a gear structure, a transmission belt structure, etc. Optionally, please refer to... Figure 22 In one embodiment of this utility model, the power input end 123 includes an input gear 1231, which is connected to the output end of the drive member 121. The drive member 121 drives the input gear 1231 to rotate. The first power output end 124 includes a first output gear 1241, and the second power output end 125 includes a second output gear 1251. The first output gear 1241 is installed between the input gear 1231 and the second output gear 1251. The first output gear 1241 is drive-connected to the input gear 1231, and the second output gear 1251 is drive-connected to the first output gear 1241.

[0134] It should be noted that the transmission connection between the first output gear 1241 and the input gear 1231 can be a direct gear meshing transmission connection or an indirect transmission connection achieved through other additional gear assemblies. Similarly, the transmission connection between the second output gear 1251 and the first output gear 1241 can also be a direct gear meshing transmission connection or an indirect transmission connection achieved through other additional gear assemblies. For details, please refer to [link to relevant documentation]. Figure 20 and Figure 22The cleaning mechanism 130 includes a bracket 132, which has a gear mounting cavity 1323. The bracket 132 is fixedly connected to the body 110 via a lifting mechanism 120. The input gear 1231, the first output gear 1241, and the second output gear 1251 are all rotatably connected to the bracket 132 and housed within the gear mounting cavity 1323. By providing the gear mounting cavity 1323, the risk of dust, particles, and other impurities entering the gear meshing area during cleaning operations can be effectively reduced, thereby reducing the possibility of gear wear or jamming and extending the service life of the gear assembly. Of course, in other embodiments, the bracket 132 may not have a gear mounting cavity 1323, and the input gear 1231, the first output gear 1241, and the second output gear 1251 may be exposed to the outside of the cleaning mechanism 130.

[0135] This embodiment achieves gear transmission between the power input end 123 and the first and second power output ends 124 and 125 by setting an input gear 1231, a first output gear 1241, and a second output gear 1251, with the first output gear 1241 drivingly connected to the input gear 1231 and the second output gear 1251 drivingly connected to the first output gear 1241. Thus, by adjusting the tooth ratio among the input gear 1231, the first output gear 1241, and the second output gear 1251, the speed, torque, and direction of rotation of the power input end 123 and the power output end can be flexibly adjusted. Therefore, it is more conducive to improving the design flexibility of the transmission mechanism 122. At the same time, the gear transmission structure also has advantages such as high transmission efficiency, compact structure, and reliable operation, thus helping to improve the operating accuracy of the transmission mechanism 122 and extend its service life.

[0136] Please see Figure 22 In one embodiment of the present invention, the transmission ratio between the input gear 1231 and the first output gear 1241 is less than the transmission ratio between the first output gear 1241 and the second output gear 1251.

[0137] In this embodiment, the transmission ratio between the input gear 1231 and the first output gear 1241 is smaller than the transmission ratio between the first output gear 1241 and the second output gear 1251. This transmission ratio setting allows for gradual deceleration of power during transmission, while simultaneously amplifying torque at each stage. This configuration ensures that the second output gear 1251 receives a larger torque, thereby more effectively driving the shielding member 140, located away from the input gear 1231, to rotate smoothly. Simultaneously, the smaller transmission ratio between the input gear 1231 and the first output gear 1241 means that the drive member 121 at the power input end 123 can operate at a higher speed while outputting a smaller torque. This operating mode helps reduce mechanical wear on the drive member 121, thus extending its service life. Furthermore, the smaller torque output also helps reduce the risk of power overload on the drive member 121, further improving the reliability and stability of the cleaning equipment 100.

[0138] Please see Figure 22 In one embodiment of this utility model, the first output gear 1241 is connected to the input gear 1231 via a first gear assembly 126. The second output gear 1251 is connected to the first output gear 1241 via a second gear assembly 127. The number of gears in the first gear assembly 126 and the second gear assembly 127 may be equal or unequal.

[0139] Optionally, please refer to Figure 22 In this embodiment, the first gear assembly 126 has one gear, which is designated as the first transmission gear 1261 for ease of description. The input gear 1231 meshes with the first transmission gear 1261, and the first transmission gear 1261 meshes with the first output gear 1241. The second gear assembly 127 has two gears. For ease of description, these two gears are designated as the second transmission gear 1271 and the third transmission gear 1272, respectively. The first output gear 1241 meshes with the second transmission gear 1271, the second transmission gear 1271 meshes with the third transmission gear 1272, and the third transmission gear 1272 meshes with the second output gear 1251. The number of teeth among the first transmission gear 1261, the second transmission gear 1271, and the third transmission gear 1272 can be equal or unequal, depending on factors such as the output speed and output torque of the first output gear 1241 and the second output gear 1251.

[0140] In the above embodiments, by setting the first gear assembly 126 and the second gear assembly 127, a variety of flexible combinations of transmission ratios can be achieved by adjusting the transmission ratio of the first gear assembly 126 and the second gear assembly 127. This allows the transmission mechanism 122 to better adapt to the different speed and torque requirements between the first output gear 1241 and the second output gear 1251, which is beneficial to improving the design flexibility of the transmission mechanism 122. At the same time, the gear assembly can achieve a large transmission ratio and high torque transmission capacity in a small space. Therefore, by reasonably designing the size and position of the gear assembly, complex power transmission can be achieved in a limited space, which not only optimizes the overall layout of the cleaning equipment 100, but also improves the flexibility of the setting position of the first output gear 1241 and the second output gear 1251.

[0141] Please see Figure 22 In one embodiment of this utility model, the transmission ratio between the input gear 1231 and the first output gear 1241 is 1, and the reduction ratio of the second gear assembly 127 is 1. The transmission ratio of the input gear 1231 to the first output gear 1241 being 1 indicates that the number of teeth among the input gear 1231, the first transmission gear 1261, and the first output gear 1241 is equal. The reduction ratio of the second gear assembly 127 being 1 indicates that the number of teeth among the second transmission gear 1271 and the third transmission gear 1272 is equal.

[0142] This configuration means, on the one hand, that the presence of the first gear assembly 126 and the second gear assembly 127 does not change the transmission ratio between the input gear 1231 and the first output gear 1241, or between the first output gear 1241 and the second output gear 1251. In other words, the first gear assembly 126 and the second gear assembly 127 primarily function as idlers. This makes the setting of the transmission ratio in the transmission mechanism 122 more flexible and convenient, and significantly simplifies the calculation process of the entire transmission system. Simultaneously, since the transmission ratio of each stage remains at 1, power transmission will not accumulate errors due to transmission ratio mismatch, thus improving the overall operating accuracy of the transmission mechanism 122. On the other hand, since the transmission ratio between the input gear 1231 and the first output gear 1241 is 1, and the reduction ratio of the second gear assembly 127 is also 1, the tooth profiles of these gears can be completely identical. This means that roughly the same gear design and manufacturing process can be used, thereby significantly reducing design and manufacturing costs.

[0143] Although this utility model does not limit the specific structural form of the lifting mechanism 120, alternatively, please refer to Figure 21 and Figure 23In one embodiment of this utility model, the lifting mechanism 120 further includes a linkage mechanism 128, through which the first output gear 1241 drives the cleaning mechanism 130 to move up and down. Specifically, see [reference needed]. Figure 16 and Figure 23 The input end of the linkage mechanism 128 is connected to the first output gear 1241, and the output end of the linkage mechanism 128 is connected to the machine body 110. The operation of the first output gear 1241 drives the linkage mechanism 128 to operate, and the operation of the linkage mechanism 128 drives the cleaning mechanism 130 to rise and fall relative to the machine body 110.

[0144] The location of the linkage mechanism 128 is not limited; for example, it can be located at the height of the cleaning mechanism 130 (e.g., ...). Figure 11 Above the Z-axis (as shown), or it can be positioned along the length of the cleaning mechanism 130 (as shown). Figure 13 The linkage mechanism 128 can be located on the side (as shown in the X-axis direction) or at other positions that meet the lifting and lowering requirements. Depending on actual needs, one or more linkage mechanisms 128 can be provided. The specific structural type of the linkage mechanism 128 can be varied; for example, it can be a double-link mechanism, a crank-slider mechanism, a multi-link combination mechanism, a gear and linkage combination mechanism, etc. The specific selection needs to be optimized based on the lifting and lowering requirements and spatial layout of the cleaning mechanism 130.

[0145] In this embodiment, the lifting mechanism 120 adopts a linkage mechanism 128. This arrangement allows the linkage mechanism 128 to achieve complex motion conversions within a limited space, making it easier to convert the rotational motion of the first output gear 1241 into the lifting motion of the cleaning mechanism 130. This facilitates a more compact overall design for the lifting mechanism 120, making it particularly suitable for cleaning equipment 100 in space-constrained environments. Furthermore, the linkage mechanism 128 can be flexibly arranged according to specific structural requirements, making it easier to install in multiple directions such as horizontal, vertical, or inclined, thus better adapting to different installation spaces and motion conversion requirements. Additionally, the main components of the linkage mechanism 128 (such as connecting rods and spherical bearings) are easy to replace and maintain. Compared to hydraulic or electric lifting methods, the linkage mechanism 128 experiences less wear and is easier to maintain.

[0146] Please see Figure 13 and Figure 23In one embodiment of this utility model, both the linkage mechanism 128 and the transmission mechanism 122 are disposed on the outer side of the cleaning mechanism 130 along its length direction, and the projection area of ​​at least one of the linkage mechanism 128 and the transmission mechanism 122 partially overlaps with the projection area of ​​the cleaning mechanism 130 along its length direction. In one embodiment, only the projection area of ​​the linkage mechanism 128 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction. In another embodiment, only the projection area of ​​the transmission mechanism 122 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction. In other embodiments, both the projection areas of the linkage mechanism 128 and the transmission mechanism 122 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction.

[0147] In this embodiment, by placing the linkage mechanism 128 and the transmission mechanism 122 on the outer side of the cleaning mechanism 130 along its length, rather than directly above it, the space occupied above the cleaning mechanism 130 can be effectively reduced, lowering the overall height of the cleaning device 100. This allows the cleaning device 100 to better adapt to height-restricted cleaning scenarios, such as cleaning work in narrow passages or low spaces. Simultaneously, placing the linkage mechanism 128 and the transmission mechanism 122 on the outer side of the cleaning mechanism 130 along its length helps maintain the center of gravity balance of the cleaning device 100, reducing swaying or instability caused by center of gravity shift during cleaning operations, thereby improving the operational stability of the cleaning device 100.

[0148] In one embodiment of this utility model, the linkage mechanism 128 includes a first link 1281 and a slider 1282. Along the length of the first link 1281, one end of the first link 1281 is fixedly connected to a first output gear 1241. The method of fixed connection is not limited; for example, the first output gear 1241 can be a gear shaft structure, and the first link 1281 can be fixedly connected to the gear shaft, thereby achieving a fixed connection with the first output gear 1241. Alternatively, the first output gear 1241 can be fixedly connected to a mounting shaft, and the first link 1281 can be fixedly mounted on the mounting shaft, thereby achieving a fixed connection with the first output gear 1241. The other end of the first link 1281 is rotatably connected to the slider 1282, and the slider 1282 is slidably connected to the body 110. The slider 1282 can take various shapes, as long as it can achieve a rotatable connection with the first link 1281. For example, the slider 1282 can be a bearing, a roller, etc. Optionally, in this embodiment, the slider 1282 is a bearing. The specific ways in which the slider 1282 is slidably connected to the body 110 include, but are not limited to, providing a groove on the body 110, and slidingly installing the slider 1282 in the groove, thereby realizing the sliding connection between the slider 1282 and the body 110.

[0149] In the above embodiments, by setting a first connecting rod 1281 and a sliding member 1282, the rotation of the first connecting rod 1281 and the sliding of the sliding member 1282 can be combined to convert the rotational motion of the first output gear 1241 into the lifting motion of the cleaning mechanism 130. This motion conversion method not only meets the lifting requirements of the cleaning mechanism 130, but also allows for flexible control of the lifting stroke of the cleaning mechanism 130 by adjusting the length of the first connecting rod 1281 or the installation position of the sliding member 1282. This improves the design flexibility of the lifting mechanism 120 and its adaptability to different working conditions. Furthermore, due to the simple structure and small number of parts of the first connecting rod 1281 and the sliding member 1282, the overall structure of the lifting mechanism 120 is more compact, facilitating installation and maintenance, and improving the operational reliability and economy of the lifting mechanism 120.

[0150] To facilitate the installation between the linkage mechanism 128 and the body 110, optionally, please refer to Figure 16 , Figure 20 , Figure 23 and Figure 24In one embodiment of this utility model, the linkage mechanism 128 includes a first link 1281, a sliding member 1282, and a second link 1283. The second link 1283 is fixedly connected to the body 110, and the fixed connection method can be a snap-fit ​​connection, a bolt connection, etc. Optionally, in this embodiment, the body 110 is provided with a slot, which matches the outer contour of the second link 1283, and the second link 1283 is snap-fitted into the slot, thereby realizing the snap-fit ​​fixed connection between the second link 1283 and the body 110. The second link 1283 is provided with a sliding groove 12831.

[0151] Along the length of the first connecting rod 1281, one end of the first connecting rod 1281 is fixedly connected to the first output gear 1241, and the other end of the first connecting rod 1281 is rotatably connected to the sliding member 1282. The sliding member 1282 is disposed in the sliding groove 12831 and slides along the extending direction of the sliding groove 12831. It should be noted that, in this embodiment, the structural form of the sliding member 1282 and the fixed connection method between the first connecting rod 1281 and the first output gear 1241 can be referred to the relevant descriptions in the above embodiments, and will not be repeated here.

[0152] In this embodiment, by adding a second connecting rod 1283 and providing a sliding groove 12831 on the second connecting rod 1283, the position of the second connecting rod 1283 on the fuselage 110 can be adjusted more flexibly as needed to achieve corresponding adjustments to the position of the sliding groove 12831. This flexibility allows the linkage mechanism 128 to better adapt to fuselage 110 structures of different sizes and shapes, as well as different installation space requirements. Furthermore, when the sliding groove 12831 experiences significant wear, the second connecting rod 1283 can be directly replaced without modifying the fuselage 110 installation structure. Therefore, this facilitates the later replacement and maintenance of the linkage mechanism 128.

[0153] Under the condition of meeting the lifting operation requirements of the cleaning mechanism 130, this utility model does not limit the sliding direction of the sliding member 1282 relative to the body 110. However, optionally, please refer to Figure 16 and Figure 24 In one embodiment of this utility model, the sliding direction of the sliding member 1282 relative to the body 110 (i.e., the extending direction of the slide groove 12831) is parallel to the traveling direction of the cleaning device 100. The traveling direction of the cleaning device 100 is as follows: Figure 16 As shown in the N-axis direction, the sliding direction of the slider 1282 is horizontal.

[0154] In this embodiment, the sliding direction of the slider 1282 relative to the body 110 is set to be parallel to the traveling direction of the cleaning equipment 100. This setting makes the positioning and installation of the slide 12831 and the body 110 more convenient and intuitive, which helps to reduce motion errors caused by assembly deviations. On the other hand, it also simplifies the calculation of the lifting stroke and sliding stroke, which not only reduces the computational complexity but also improves the control accuracy of the linkage mechanism 128's running trajectory.

[0155] Please see Figures 22 to 27 In one embodiment of this utility model, the rotational speed of the first output gear 1241 is greater than that of the second output gear 1251. During the operation of the drive unit 121, the first output gear 1241 gradually leads the second output gear 1251 in angular position, thereby creating a phase difference between the first output gear 1241 and the second output gear 1251. Please refer to [link / reference]. Figure 24 and Figure 32 The first connecting rod 1281 includes a rod body 12811 and a connecting part 12812. One end of the rod body 12811 is rotatably connected to the slider 1282, and the other end of the rod body 12811 is slidably connected to the connecting part 12812 via a sliding assembly 1284. The connecting part 12812 is fixedly connected to the first output gear 1241. It should be noted that in this embodiment, the fixed connection method between the connecting part 1281 and the first output gear 1241 can refer to the fixed connection method between the first connecting rod 1281 and the first output gear 1241 in the above embodiments, and the structural description of the slider 1282 can also refer to the structural description of the slider 1282 in the above embodiments, and will not be repeated here.

[0156] Specifically, in this embodiment, the slider 1282 is a bearing, and the first output gear 1241 is a gear shaft structure. The first output gear 1241 is rotatably connected to the bracket 132 via the bearing. Please refer to [link to previous text]. Figure 26 and Figure 32 The connecting part 12812 includes a flange end 12813 and a plug-in end 12814. A first plug-in hole 12411 is provided at one end of the first output gear 12411 facing the connecting part 12812. The plug-in end 12814 is fixedly engaged within the first plug-in hole 12411 to achieve a fixed connection between the connecting part 12812 and the first output gear 1241. The rod part 12811 is rotatably connected to the plug-in end 12814, and along the axial direction of the first output gear 1241, the rod part 12811 is located between the flange end 12813 and the first output gear 1241.

[0157] During the rotation of the first output gear 1241, the connecting part 12812 rotates with the first output gear 1241 to a preset angle, and then drives the rod part 12811 to rotate synchronously through the sliding assembly 1284. The sliding assembly 1284 can have various structures. For example, the sliding assembly 1284 can include a first sliding member and a second sliding member that cooperate with each other, with the first sliding member sliding along the second sliding member. The first sliding member and the second sliding member can be a slider and groove structure, or a guide rail and slider structure, etc.

[0158] Specifically, the first sliding member and the second sliding member are respectively disposed at the ends of the connecting portion 12812 and the rod portion 12811. In the initial stage of the rotation of the first output gear 1241, the first output gear 1241 drives the connecting portion 12812 to rotate synchronously, and the first sliding member slides along the second sliding member. At this time, the rod portion 12811 remains stationary relative to the connecting portion 12812. When the connecting portion 12812 rotates to a preset angle with the first output gear 1241, the first sliding member and the second sliding member form a stop engagement, and sliding between them stops. As the first output gear 1241 continues to rotate, the first sliding member and the second sliding member will rotate synchronously as a whole, thereby driving the rod portion 12811 to rotate synchronously with the first output gear 1241.

[0159] Since the rotational speed of the first output gear 1241 is greater than that of the second output gear 1251, a phase difference will inevitably occur between them during rotation. If left uncontrolled, this phase difference will cause the lifting and lowering operation of the cleaning mechanism 130 and the rotation of the shielding member 140 to be out of sync, thus affecting the normal operation of the cleaning equipment 100. In this embodiment, by providing a sliding component 1284 between the rod portion 12811 and the connecting portion 12812, when the first output gear 1241 rotates, the connecting portion 12812 will first rotate with the first output gear 1241 to a preset angle, and then drive the rod portion 12811 to rotate synchronously via the sliding component 1284. This design allows the connecting portion 12812 to rotate independently in the initial stage of the first output gear 1241's rotation, while the rod portion 12811 remains stationary, thus providing a buffer space for the phase difference. After the connecting portion 12812 rotates to the preset angle, it will again drive the rod portion 12811 to rotate synchronously via the sliding component 1284. In this way, during the final stage of the lifting operation, the lifting action of the cleaning mechanism 130 and the rotation action of the shielding component 140 can be synchronized, thereby ensuring the normal cleaning operation of the cleaning equipment 100.

[0160] Please see Figures 24 to 26In one embodiment of this utility model, the sliding component 1284 includes an arc-shaped groove 12841 and a protrusion 12842. The arc-shaped groove 12841 is disposed on the rod portion 12811, and the protrusion 12842 is disposed on the connecting portion 12812. The protrusion 12842 slides along the arc-shaped groove 12841, and the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241. In another embodiment, the arc-shaped groove 12841 may be disposed on the connecting portion 12812, and the protrusion 12842 may be disposed on the rod portion 12811. The protrusion 12842 slides along the arc-shaped groove 12841, and the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241.

[0161] In this embodiment, by configuring the sliding component 1284 as an arc-shaped groove 12841 and a protrusion 12842, on the one hand, the protrusion 12842 slides along the arc-shaped groove 12841, forming a stable guiding structure. This ensures that the relative motion trajectory between the rod body 12811 and the connecting part 12812 is precisely controllable, thereby reducing the probability of deviation or wobbling between them during movement. On the other hand, since the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241, the motion trajectory of the sliding component 1284 is consistent with the rotational motion of the first output gear 1241, thereby further improving the stability and accuracy of operation.

[0162] Considering the smoothness of the lifting and lowering operation of the cleaning mechanism 130 relative to the body 110, optionally, please refer to Figures 30 to 31 In one embodiment of this utility model, two sets of linkage mechanisms 128 are provided, and the two sets of linkage mechanisms 128 are respectively arranged on both sides of the outer side of the cleaning mechanism 130 along its length. One set of linkage mechanisms 128 and the transmission mechanism 122 are located on the same side of the cleaning mechanism 130 along its length. The two sets of linkage mechanisms 128 can be symmetrically arranged on both sides of the cleaning mechanism 130 or asymmetrically arranged. In this embodiment, the two sets of linkage mechanisms 128 are symmetrically arranged on both sides of the cleaning mechanism 130 along its length. The two sets of linkage mechanisms 128 are connected by a synchronization mechanism 150. When the first output gear 1241 rotates, the synchronization mechanism 150 can realize the synchronous operation of the two sets of linkage mechanisms 128.

[0163] There are various specific structural arrangements for connecting the two sets of linkage mechanisms 128 via the synchronization mechanism 150. For example, in one embodiment, a synchronization shaft can be provided between the two sets of linkage mechanisms 128. The two ends of the synchronization shaft are fixedly connected to the input ends of the linkage mechanisms 128 on both sides. The synchronization shaft is supported on the bracket 132 of the cleaning mechanism 130 by bearings, and one end of the synchronization shaft is fixedly connected to the first output gear 1241. When the first output gear 1241 rotates, the synchronization shaft synchronously transmits the rotation of the first output gear 1241 to the linkage mechanism 128 on the side away from the first output gear 1241, thereby achieving synchronous operation of the two linkage mechanisms 128.

[0164] In another embodiment, a synchronous pulley assembly can be provided on the two linkage mechanisms 128. The driving pulley in the synchronous pulley assembly is fixedly connected to the first output gear 1241, and the driven pulley in the synchronous pulley assembly is connected to the input end of the linkage mechanism 128 on the side away from the first output gear 1241. When the first output gear 1241 rotates, the synchronous pulley assembly synchronously transmits the rotation of the first output gear 1241 to the linkage mechanism 128 on the side away from the first output gear 1241, thereby realizing the synchronous operation of the two linkage mechanisms 128.

[0165] In this embodiment, by arranging two sets of linkage mechanisms 128 on the outer sides of the cleaning mechanism 130 along its length, a dual-sided synchronous drive structure can be formed. This structure allows the lifting and lowering motion of the cleaning mechanism 130 to be completed jointly by the linkage mechanisms 128 on both sides, thereby achieving a uniform distribution of force during the lifting and lowering process. Compared with a single-sided drive scheme, the dual-sided synchronous drive structure can effectively avoid the risk of uneven load and prevent problems such as swaying or movement jamming caused by uneven force, thereby improving the smoothness and accuracy of the lifting and lowering operation of the cleaning mechanism 130. In addition, since the dual-sided synchronous drive structure can form a dual-sided support structure on both sides of the cleaning mechanism 130 along its length, it can enhance the overall rigidity and load-bearing capacity of the cleaning mechanism 130. This not only helps to enhance the cleaning mechanism 130's ability to withstand the loads and impacts generated during cleaning operations, but also effectively extends the service life of the cleaning equipment 100.

[0166] Please see Figures 31 to 33In one embodiment of this utility model, the synchronization mechanism 150 includes a drive shaft 151 and a support base 152. The support base 152 is rotatably connected to the end of the cleaning mechanism 130 away from the first output gear 1241. Specifically, the support base 152 is rotatably connected to the end of the bracket 132 away from the first output gear 1241. The rotatable connection method includes, but is not limited to, rotatably connecting the bracket 132 via a slewing bearing. The drive shaft 151 extends along the length direction of the cleaning mechanism 130, one end of the drive shaft 151 is fixedly connected to the first output gear 1241, and the other end of the drive shaft 151 is fixedly connected to the support base 152. The fixed connection method between the drive shaft 151, the first output gear 1241, and the support base 152 is not limited; it can be a snap-fit ​​connection or a bolt connection, etc.

[0167] Specifically, please refer to Figure 32 In this embodiment, the drive shaft 151 has a locking portion 1511 at both ends, the first output gear 1241 has a first locking hole 12412 at the end facing away from the connecting portion 12812, and the support base 152 has a second locking hole 1521 at the end facing the drive shaft 151. One locking portion 1511 is locked into the first locking hole 12412 to achieve a fixed connection between the drive shaft 151 and the first output gear 1241. The other locking portion 1511 is locked into the second locking hole 1521 to achieve a fixed connection between the drive shaft 151 and the support base 152.

[0168] One set of the two linkage mechanisms 128 is fixedly connected to the first output gear 1241, and the other set is fixedly connected to the support base 152. The method of fixing the linkage mechanism 128 closer to the first output gear 1241 to the first output gear 1241 can be referred to the relevant description in the above embodiments, and will not be repeated here. The method of fixing the linkage mechanism 128 farther from the first output gear 1241 to the support base 152 can be varied, such as snap-fit ​​fixing or bolt fixing. For details, please refer to... Figure 33 In this embodiment, on the side of the drive shaft 151 away from the first output gear 1241, the support base 152 is provided with a second insertion hole 1522 at the end opposite to the drive shaft 151. The insertion end 12814 of the connecting part 12812 is fixedly engaged in the second insertion hole 1522 to realize the fixed connection between the connecting part 12812 and the support base 152, that is, to realize the connection between the connecting rod mechanism 128 on this side and the support base 152.

[0169] In this embodiment, by setting up a transmission shaft 151 and a support base 152, when the first output gear 1241 rotates, part of its power is transmitted to the corresponding linkage mechanism 128, driving the linkage mechanism 128 to move. Another part of the power can be transmitted through the transmission shaft 151 to the support base 152, which then drives the corresponding linkage mechanism 128 to operate, thereby achieving synchronous operation of the linkage mechanisms 128 on both sides. Since both ends of the transmission shaft 151 are fixedly connected to the support base 152 and the first output gear 1241 respectively, a rigid connection structure can be formed. This structure ensures that the power of the first output gear 1241 can be directly transmitted to the support base 152 through the transmission shaft 151, thereby driving the two sets of linkage mechanisms 128 to move synchronously. This avoids the elastic deformation or slippage that may occur with flexible connections (such as belts or chains), which is beneficial for ensuring the accuracy of synchronous transmission.

[0170] Please see Figure 13 , Figure 36 and Figure 38 In this embodiment, the support assembly 133 adopts a roller structure. The blocking member 140 includes an arc-shaped plate 141 and connecting plates 142 disposed at both ends of the arc-shaped plate 141. The rotation axis of the arc-shaped plate 141 is coaxially arranged with the rotation axis of the support assembly 133. The connecting plates 142 at both ends are rotatably connected to both ends of the support assembly 133. One of the connecting plates 142 is fixedly connected to the second output gear 1251. The fixed connection can be integrally injection molded or fixed with bolts. In this embodiment, in order to facilitate the installation between the second output gear 1251 and the blocking member 140, the second output gear 1251 and the blocking member 140 are integrally injection molded.

[0171] Please see Figure 11 , Figure 37 and Figure 39 In one embodiment of this utility model, the cleaning device 100 further includes a first detection component 174 and a second detection component 180. The first detection component 174 is used to detect whether the cleaning mechanism 130 is in a raised position and whether the blocking member 140 is in a first rotation position. The second detection component 180 is used to detect whether the cleaning mechanism 130 is in a lowered position and whether the blocking member 140 is in a second rotation position. The first detection component 174 and the second detection component 180 can have various structural types. For example, the first detection component 174 and the second detection component 180 can be a combination structure of Hall sensor and magnet, a combination structure of mechanical switch and stop, a combination structure of photoelectric switch and baffle, etc.

[0172] It should be noted that in this invention, the lifting and lowering movement of the cleaning mechanism 130 and the rotational movement of the blocking member 140 are always synchronized at the final position. Specifically, when the cleaning mechanism 130 is in the raised position, the blocking member 140 rotates synchronously to the first position; when the cleaning mechanism 130 is in the lowered position, the blocking member 140 rotates synchronously to the second position. This ensures the coordination of the positions of the cleaning mechanism 130 and the blocking member 140 at the end of the operation.

[0173] In this embodiment, the first detection component 174 may be disposed on the bracket 132 of the body 110 and the cleaning mechanism 130, and is used to detect whether the cleaning mechanism 130 is in the raised position. Alternatively, the first detection component 174 may be disposed on the shield 140 and the bracket 132, and is used to detect whether the shield 140 is in the first rotation position. The second detection component 180 may be disposed on the body 110 and the bracket 132, and is used to detect whether the cleaning mechanism 130 is in the lowered position. Alternatively, the second detection component 180 may be disposed on the shield 140 and the bracket 132, and is used to detect whether the shield 140 is in the second rotation position.

[0174] Specifically, in this embodiment, please refer to Figure 39 The first detection component 174 includes a first detection switch 1741 and a first stop 1742. The first detection switch 1741 is mounted on the body 110, and the first stop 1742 is mounted on the bracket 132, with their positions corresponding to each other. When the cleaning mechanism 130 rises to the raised position, the first stop 1742 triggers the first detection switch 1741, generating a first positioning detection signal. At this time, the controller of the cleaning equipment 100 (or the controller built into the drive unit 121) receives the first positioning detection signal and controls the drive unit 121 to stop running, thereby synchronously stopping the lifting movement of the cleaning mechanism 130 and the rotation movement of the shield 140.

[0175] Please see Figure 37 The second detection component 180 includes a second detection switch 181 and a second stop 182. The second detection switch 181 is mounted on the bracket 132, and the second stop 182 is mounted on the connecting plate 142 and positioned close to the second detection switch 181. The second stop 182 can be integrally formed with the connecting plate 142 or fixedly connected by bolts. In this embodiment, the second stop 182 is integrally formed with the connecting plate 142. When the blocking member 140 rotates to the second rotation position, the second stop 182 triggers the second detection switch 181, generating a second positioning detection signal. At this time, the controller (or the controller built into the drive member 121) receives the second positioning detection signal and controls the drive member 121 to stop running, thereby synchronously stopping the lifting movement of the cleaning mechanism 130 and the rotation of the blocking member 140.

[0176] In this embodiment, by integrating the detection of the lifting position of the cleaning mechanism 130 and the rotation position of the blocking member 140 into the same detection component, separate detection components for the lifting operation of the cleaning mechanism 130 and the rotation operation of the blocking member 140 are avoided. This integrated design not only effectively reduces the total number of detection components and simplifies the overall number of parts, but also helps to reduce manufacturing costs. At the same time, the integrated detection component can simultaneously acquire the position status of the cleaning mechanism 130 and the blocking member 140, reducing the number of signal acquisition and processing steps, thereby improving detection efficiency and the response speed of the control system, which is conducive to achieving more precise motion control.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
