Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cleaning component. Furthermore, it also relates to a cleaning device including this cleaning component. Background Technology

[0002] With the development trend of modern smart homes, cleaning equipment, such as robotic vacuum cleaners and traditional vacuum cleaners, is becoming an indispensable automated cleaning tool in both home and commercial environments. To facilitate floor cleaning, these devices are typically designed with air ducts and suction ports for drawing in dust and debris. Furthermore, to improve cleaning effectiveness, these air ducts often include roller brushes to transport dust and debris from the floor to the suction port through their rotation. This combination of suction ducts and roller brushes is widely used in various cleaning products.

[0003] However, during the rotation of the roller brush, fine and flexible objects such as hair, lint, and fabric fibers are easily attracted by the bristles and continuously coil around the brush shaft, forming tangles on the roller brush. This not only hinders the roller brush's further pickup ability, resulting in incomplete cleaning of the floor area, but also causes the motor current to increase or even overload and shut down, damaging the motor, shortening the overall lifespan, and reducing the reliability of the cleaning equipment. To solve the problem of filamentous foreign objects entangled in the roller brush, users usually need to disassemble the roller brush and manually peel off the tangles, a cumbersome process that affects the user experience and can only be done after cleaning is complete.

[0004] Therefore, there is an urgent need to provide a cleaning component that can directly prevent filamentous foreign objects from getting tangled on the cleaning parts. Utility Model Content

[0005] To achieve the above objectives, a first aspect of the present invention provides a cleaning assembly comprising: The housing has an air duct formed inside it, which is connected to the suction port on the housing in a breathable manner; The cleaning component is rotatably mounted within the housing; and a baffle is switchable between a first position and a second position, wherein when the baffle is in the first position, the cleaning component is exposed outward through the suction port, causing the cleaning component to rotate under drive and brush the surface to be cleaned; when the baffle is in the second position, the cleaning component is blocked by the baffle so that the airflow drawn in through the suction port is isolated from the cleaning component.

[0006] In some embodiments, the baffle includes a main body and a mating portion disposed at the end of the main body. The mating portion is configured to make airtight contact with the inner wall of the cavity of the housing, so that the air duct is connected to or isolated from the cleaning component when the baffle is in a first position or a second position, respectively.

[0007] In some embodiments, the mating part is made of a soft material so that it can be pressed against the inner wall of the cavity to form an airtight seal.

[0008] In some embodiments, the mating part is made of a rigid material, and at least part of the inner wall of the cavity is made of a soft material, so that the mating part can press against the inner wall of the cavity made of soft material and form an airtight seal.

[0009] In some embodiments, the mating part is detachably mounted to the end of the baffle.

[0010] In some embodiments, the body is made of a rigid material.

[0011] In some embodiments, the baffle is configured to be radially spaced from the inner wall of the cavity of the housing, and the mating portion extends from the baffle toward the inner wall of the cavity to form an extension whose end presses against the inner wall of the cavity.

[0012] In some embodiments, a mating seat is provided on the inner wall of the cavity, which can engage with the extension on the baffle when the baffle is rotated to the first position, so as to limit the baffle to the first position.

[0013] In some embodiments, the mating seat is provided with a groove that can mate with the extension section. The groove mates with the extension section when the baffle is rotated to a first position, so as to form a stepped seal between the groove and the extension section while limiting the baffle to the first position.

[0014] In some embodiments, the baffle includes an arcuate plate coaxially disposed with the cleaning member, the arcuate plate being configured to partially surround the outer periphery of the cleaning member, and being adjustable to rotate about the cleaning member and switch between a first position and a second position.

[0015] In some embodiments, the cleaning component and the baffle are respectively driven to the same drive component, which is configured to switch between forward and reverse rotation and to drive the cleaning component and the baffle to rotate during operation; The cleaning component and the driving component are connected by a one-way transmission structure so that the cleaning component is driven to rotate when the driving component rotates forward, and is not driven by the driving component when the driving component rotates in reverse. The baffle is connected to the drive component via a transmission structure including a disengagement mechanism, so that it is driven to rotate to a first position when the drive component rotates forward and to rotate to a second position when the drive component rotates in reverse. At the same time, when the baffle rotates to the first or second position, the drive component is allowed to disengage from the transmission structure of the baffle and operate on its own to avoid overloading the drive component.

[0016] In some embodiments, a scraper is also provided at the suction port, the scraper extending out of the suction port to guide waste into the housing.

[0017] In some embodiments, the system further includes a drive component and a control module for driving the baffle, the control module being able to control the drive component to drive the baffle to switch between a first position and a second position.

[0018] In some embodiments, the cleaning component further includes a user terminal, which is signal-connected to the control module and is used to receive user instructions and send them to the control module, and the control module controls the drive component according to the user instructions; and / or: the cleaning component further includes an identification device, which is signal-connected to the control module and is used to identify and determine whether there are filamentous foreign objects on the surface being cleaned, generate a determination result signal and send it to the control module, and the control module controls the drive component according to the determination result signal.

[0019] A second aspect of the present invention provides a cleaning device, wherein the cleaning component described above is ventilably connected to a fan and a dust box in the cleaning device, and cooperates with the fan to suck foreign objects on the surface to be cleaned into the dust box.

[0020] In the above technical solution, the baffle and the housing form an air duct. One end of the air duct is a suction port facing the surface to be cleaned, and the other end is connected to a fan or other device inside the cleaning equipment that can generate negative pressure within the air duct. This allows dust and debris on the surface to be cleaned, as indicated by the suction port, to be sucked into the cleaning equipment, thereby cleaning the floor. A cleaning component is also provided at the suction port. This component can be driven to rotate and contact the surface to be cleaned, thereby conveying dust and debris from the surface to be cleaned from the suction port into the air duct.

[0021] When there are no filamentous foreign objects on the surface being cleaned, the baffle is in the first position, and the cleaning component can be exposed to the outside through the suction port of the air duct, so that it can contact the surface being cleaned and perform cleaning; when there are filamentous foreign objects on the surface being cleaned, the baffle moves to the second position, that is, moves between the surface being cleaned and the cleaning component, so as to separate the cleaning component and the surface being cleaned, and prevent the filamentous foreign objects on the surface being cleaned from being carried by the cleaning component and entangled on the cleaning component, which would cause the cleaning component to operate abnormally.

[0022] Specifically, the cleaning component is a roller brush with bristles. When the roller brush cleans the surface being cleaned, it is driven to rotate. The soft bristles on the roller brush contact the surface being cleaned, carrying up dust and debris, which can then be drawn into the cleaning equipment through the air duct, thus cleaning the surface. When the baffle is in the second position, the soft bristles can be rolled up by the baffle and housed in the space above the baffle, preventing the bristles from being exposed. The baffle in the second position is configured to maintain a certain distance between its outer surface and the surface being cleaned, preventing friction damage. Because the bristles are made of a soft material, even if there is a gap between the baffle and the surface being cleaned when the baffle moves to the second position, the bristles can be bent and housed above the baffle.

[0023] The technical solution of this utility model can ensure the normal operation of the cleaning component when there are no filamentous foreign objects on the surface being cleaned, and can promptly isolate the cleaning component from the surface being cleaned when filamentous foreign objects are present, so as to prevent the filamentous foreign objects from getting entangled on the cleaning component and hindering its normal operation.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0034] To achieve the above objectives, the first aspect of this utility model provides a cleaning component, such as... Figure 1 and Figure 2 As shown, it includes: The housing 1 has an air duct formed inside it, and the air duct is ventilably connected to the suction port 11 on the housing 1. Cleaning component 2, which is rotatably mounted inside housing 1; And a baffle 3, which can switch between a first position and a second position. When the baffle 3 is in the first position, the cleaning component 2 is exposed to the outside through the suction port 11, so that the cleaning component 2 rotates under the drive and brushes the surface to be cleaned. When the baffle 3 is in the second position, the cleaning component 2 is blocked by the baffle 3 so that the airflow drawn in through the suction port 11 is isolated from the cleaning component 2.

[0035] The above Figure 1 and Figure 2 A schematic diagram of the cross-sectional structure obtained by cutting the cleaning component 2 along the radial direction of the cleaning component 2 provided by this utility model.

[0036] In the above technical solution, an air duct is formed inside the housing 1. One end of the air duct is a suction port 11 facing the surface to be cleaned, and the other end is connected to a fan or other device inside the cleaning equipment that can generate negative pressure within the air duct. This allows dust and debris on the surface to be cleaned, as indicated by the suction port 11, to be sucked into the cleaning equipment, thereby cleaning the floor. A cleaning component 2 is also provided at the suction port 11. The cleaning component 2 can be driven to rotate and contact the surface to be cleaned, thereby conveying dust and debris on the surface to be cleaned from the suction port 11 into the air duct.

[0037] When there are no filamentous foreign objects on the surface to be cleaned or the amount of filamentous foreign objects is less than a preset value, the baffle 3 is in the first position, and the cleaning component 2 can be exposed to the outside through the suction port 11 of the air duct, so as to contact the surface to be cleaned and perform cleaning; when there are filamentous foreign objects on the surface to be cleaned or the amount of filamentous foreign objects is greater than the preset value, the baffle 3 moves to the second position, that is, moves between the surface to be cleaned and the cleaning component 2, so as to separate the cleaning component 2 from the suction airflow in the air duct, thereby preventing the filamentous foreign objects carried by the suction airflow from getting tangled on the cleaning component 2, causing the cleaning component 2 to operate abnormally.

[0038] It is understood that negative pressure can be generated inside the air duct in any way. In this utility model, the suction port 11 refers to the entrance of the air duct into which external air and dust and garbage on the surface being cleaned enter. It is common knowledge in the field that the surface is cleaned by the air duct with negative pressure inside, and will not be elaborated here.

[0039] The cleaning component 2 can be any cleaning component 2 that can be set in the suction port 11 to cooperate with the air duct described above, such as a roller brush, cleaning cloth strip, scraper or a combination of the aforementioned components.

[0040] Without interfering with the suction port 11, the inner wall 12 of the cavity, and the cleaning component 2, the shape and movement of the baffle 3 can be configured to cooperate with each other to ensure that the baffle 3 can be fixed in the first position and the second position under the drive of the driving component, and can move between the first position and the second position. It also ensures that when the baffle 3 is in the first position, the cleaning component 2 is exposed to the outside through the suction port 11, and when it is in the second position, it can block the cleaning component 2 to isolate the cleaning component 2 from the airflow sucked in by the suction port 11.

[0041] As one embodiment of the shape and movement of the baffle 3 described above, the baffle 3 can be configured as two baffles 3 that can retract in the first position and extend in the second position. One baffle 3 is positioned in the air duct along the airflow direction when it extends, and the other baffle 3 extends from below the cleaning component 2 to isolate the cleaning component 2 from the surface being cleaned. The two baffles 3 extend along their respective extension directions and converge when they move to the second position to completely isolate the cleaning component 2 from the airflow.

[0042] In another embodiment of the shape and movement of the baffle 3 described above, the baffle 3 can be configured as an arc-shaped plate that rotates coaxially with the cleaning component 2 and covers the outer periphery of the cleaning component 2, switching between a first position and a second position by rotation.

[0043] The surface to be cleaned refers to the surface opposite the suction port 11, which can be cleaned by the air duct and the cleaning component 2 disposed therein, such as a floor or wall. The cleaning component provided by this utility model can be applied to a variety of cleaning devices for cleaning different surfaces, or to a single cleaning device capable of cleaning different surfaces.

[0044] Filamentous foreign objects refer to filamentous foreign objects that can be collected by the cleaning component 2 and the air duct and enter the air duct, such as hair or filamentous plastic strips.

[0045] In some embodiments, to ensure that the cleaning component 2 can contact the surface to be cleaned when the baffle 3 is in the first position, and to ensure that the distance between the cleaning component 2 and the surface to be cleaned is greater than the thickness of the baffle 3 when the baffle 3 is in the second position, the baffle 3 can be moved between the cleaning component 2 and the surface to be cleaned. The cleaning component 2 can be connected to a lifting mechanism disposed inside the cleaning equipment. When the baffle 3 moves to the first position, the cleaning component 2 is driven by the lifting mechanism to move downward to contact the surface to be cleaned; when the baffle 3 moves to the second position, the cleaning component 2 is driven by the lifting mechanism to move upward to the distance between it and the surface to be cleaned that is greater than the thickness of the baffle 3. By using the above-mentioned lifting mechanism to drive the baffle 3, the baffle 3 will not conflict with the cleaning component 2 or contact the ground when moving between the first and second positions, thus preventing damage to the baffle 3.

[0046] In some embodiments, such as Figure 1and Figure 2 As shown, the cleaning component 2 is configured as a roller brush, which has bristles and / or brush strips made of soft material. When the roller brush cleans the surface being cleaned, it is driven to rotate, and the soft bristles and / or brush strips on the roller brush contact the surface being cleaned, carrying up dust and debris. This allows the dust and debris to enter the cleaning equipment through the air duct, thereby cleaning the surface. When the baffle 3 is in the second position, the edges of the soft bristles and / or brush strips can be rolled up by the baffle 3 and accommodated in the space above the baffle 3, thus preventing the bristles and / or brush strips from being exposed. The baffle 3 in the second position is configured to maintain a certain distance between its outer surface and the surface being cleaned, thereby preventing the baffle 3 from being damaged by friction with the surface being cleaned. Because the bristles and / or brush strips are made of soft material, when the baffle 3 moves to the second position, even if there is a gap between the baffle 3 and the surface being cleaned, the bristles can be bent and accommodated above the baffle 3.

[0047] The technical solution of this utility model can ensure the normal operation of the cleaning component 2 when there are no filamentous foreign objects on the surface being cleaned, and can promptly isolate the cleaning component 2 from the surface being cleaned when filamentous foreign objects are present, so as to prevent the filamentous foreign objects from getting tangled on the cleaning component 2 and hindering its normal operation.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the baffle 3 includes a main body 31 and a mating part 32 disposed at the end of the main body 31. The mating part 32 is configured to be in airtight contact with the inner wall 12 of the cavity of the housing 1, so that the air duct is connected to or isolated from the cleaning component 2 when the baffle 3 is in the first position or the second position, respectively.

[0049] The mating part 32 can be configured as any structure capable of forming an airtight seal with the inner wall 12 of the cavity, for example, made of a soft material, and driven to press against the inner wall 12 of the cavity to form a seal.

[0050] In some embodiments, the mating portion 32 is made of a rigid material, and at least a portion of the inner wall 12 of the cavity is made of a soft material, so that the mating portion 32 can press against the inner wall 12 of the cavity made of soft material and form an airtight seal. By setting the mating portion 32 to be made of a rigid material and setting the portion of the inner wall 12 of the cavity that contacts the mating portion 32 to be made of a soft material, an airtight seal can be formed between the mating portion 32 and the soft inner wall 12 when the mating portion 32 abuts against the inner wall 12 of the cavity.

[0051] When the baffle 3 moves to the first or second position, at least one mating part 32 on the baffle 3 is in close contact with the inner surface of the inner wall 12 of the cavity, so as to form an air duct with a suction port 11. Furthermore, when the baffle 3 moves to the second position, it can completely isolate the suction port 11 from the cleaning component 2. When the baffle 3 is in the second position, after the mating part 32 is in contact with the inner wall 12 of the cavity, the airflow cannot enter the area where the cleaning component 2 is located between the baffle 3 and the inner wall 12 of the cavity, but must directly enter the downstream fan or dust collection chamber through the suction port 11 along the air duct. In this way, the cleaning component 2 is separated from the suction airflow, thereby reducing the likelihood of debris or filamentous foreign objects brought by the suction airflow in the air duct being driven to the surface of the cleaning component 2 and becoming entangled due to suction.

[0052] In some embodiments, to improve the sealing effect of the mating part 32, a groove corresponding to the mating part 32 may be provided on the inner wall 12 of the cavity. When the baffle 3 is in the first position or the second position, the corresponding mating part 32 can fall into the groove and cooperate with the groove to form a seal. This groove not only increases the area of ​​the sealing surface formed between the mating part 32 and the inner wall 12 of the cavity, but also prevents temporary sealing failure caused by the mating part 32 disengaging from the inner wall 12 of the cavity due to vibration when the cleaning equipment vibrates.

[0053] In some embodiments, the mating part 32 is made of a soft material so that it can be pressed against the inner wall 12 of the cavity to form an airtight seal.

[0054] The mating part 32 can be made of any soft material with good elasticity and durability, such as silicone rubber or other soft materials commonly used in the industry.

[0055] The mating part 32 can be formed into a shape that can cooperate with the end of the baffle 3 and be fitted into the end, or it can be fixed to the end of the main body 31 of the baffle 3 by adhesive bonding, or it can be integrally formed with the main body 31 to form the baffle 3. This integral forming method can be by using a soft material to wrap the hard main body 31, thereby forming a soft mating part 32 at the end of the main body 31, or it can be other methods known in the prior art that can form the baffle 3 including the above-mentioned mating part 32.

[0056] The cross-sectional shape of the surface of the mating part 32 that mates with the inner wall 12 of the cavity can be designed to be any shape that can mate with the inner wall 12 of the cavity, as long as the mating part 32 can be compressed and deformed to fit the inner wall 12 of the cavity to form a sealing surface when it comes into contact with the inner wall 12 of the cavity. For example, when the inner wall 12 of the cavity is set as an arc surface, the cross-sectional shape of the surface of the mating part 32 that mates with the inner wall 12 of the cavity, that is, the end of the mating part 32, can be set as an arc surface with the same curvature as the arc surface of the inner wall 12 of the cavity, thereby obtaining a larger sealing surface and forming a better sealing effect.

[0057] When the baffle 3 is driven to the first or second position, the mating part 32 abuts against the inner wall 12 of the cavity. Since the mating part 32 is made of a soft material, it undergoes elastic deformation upon contact with the inner wall 12, thus conforming to the inner wall surface and filling any possible tiny gaps to form a continuous sealing surface. This structure maintains stable sealing performance, allowing the baffle 3 to form a highly airtight air duct in the first or second position, ensuring negative pressure at the suction port 11 and preventing a decrease in suction cleaning effect due to airflow leakage in the air duct.

[0058] In some embodiments, to improve the sealing effect between the mating part 32 and the inner wall 12 of the cavity, the shape of the mating surface of the mating part 32 and the inner wall 12 of the cavity can be set to be consistent with the shape of the cross section of the inner wall 12 of the cavity. For example, when the inner wall 12 of the cavity is set as an arc surface, the mating surface of the mating part 32 is set as an arc surface with the same curvature as the inner wall 12 of the cavity, so that when the mating part 32 is pressed against the inner wall 12 of the cavity, a larger sealing surface is obtained, thereby providing a better sealing effect.

[0059] In some embodiments, the mating part 32 is detachably mounted to the end of the baffle 3. Since the mating part 32 engages with the inner wall 12 of the cavity during operation, its mating surface rubs against the inner wall 12 for extended periods, which may lead to wear and seal failure after prolonged use. To facilitate quick repair and replacement of the mating part 32, it can be detachably mounted to the end of the baffle 3. For example, corresponding grooves and protrusions can be provided at the ends of the mating part 32 and the main body 31, respectively. This allows for quick installation of the mating part 32 when it is mounted to the end of the main body 31, and for quick removal and replacement of the mating part 32 when it is damaged. With this configuration, faults in the mating part 32 can be repaired through rapid replacement.

[0060] In some embodiments, the baffle 3 further includes a main body portion 31 disposed between the mating portions 32, the main body portion 31 being made of a hard material. The main body portion 31 is disposed between the two mating portions 32 at the ends of the baffle 3, and its hardness is significantly higher than that of the mating portions 32, so as to reduce the deformation of the baffle 3 when the mating portions 32 abut against the inner wall 12 of the cavity.

[0061] Figure 3 The image shows a baffle 3 in one embodiment of the present invention. One end of the baffle 3 is provided with a normally disposed mating part 32, and the other end is provided with a mating part 32 having an extension. The main body 31 is disposed between the two mating parts 32 to reduce the deformation of the baffle 3.

[0062] When the cleaning equipment is running, the negative pressure generated by the fan acts on the inside of the air duct. If the baffle 3 is entirely made of soft material, the negative pressure inside the air duct may cause the baffle 3 to deform inward, reducing the flow cross-section. Furthermore, the deformation may prevent the mating part 32 from abutting against the inner wall 12 of the cavity, leading to sealing failure. By providing a rigid main body 31, its rigid structure can withstand the negative pressure load, preventing excessive deformation of the baffle 3 under stress and ensuring that the airflow in the sealed state is not affected.

[0063] Meanwhile, when larger debris such as dust, paper scraps, and plastic pieces enter the suction port 11, they will impact the baffle 3. At this time, the rigid main body 31 can provide support, so that the formed air duct remains in its original shape, preventing the baffle 3 from collapsing or bending due to the impact, thereby ensuring that the airflow channel is unobstructed.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the baffle 3 is arranged to be radially spaced from the inner wall 12 of the cavity of the housing 1, and the mating part 32 extends from the baffle 3 toward the inner wall 12 of the cavity so as to form an extension 321 whose end is pressed against the inner wall 12 of the cavity.

[0065] During the movement of the baffle 3, a certain radial clearance is provided to prevent interference between the baffle 3 and the cleaning component 2. The length of the extension section is set to be slightly larger than the aforementioned radial clearance so that it can be compressed and form a seal when it enters the radial clearance and presses against the inner wall 12 of the cavity. The end of the extension section can be made into an angled lip shape to reduce frictional resistance during initial contact and guide the extension section 311 to smoothly conform to the inner wall 12 of the cavity.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the baffle 3 includes an arcuate plate coaxially arranged with the cleaning member 2, the arcuate plate being configured to partially surround the outer periphery of the cleaning member 2, and being adjustable to rotate around the cleaning member 2 to switch between a first position and a second position.

[0067] Specifically, the cleaning component 2 is installed inside the housing 1. The baffle 3 includes an arc-shaped plate and a bracket connected to the arc-shaped plate. One end of the bracket is fixedly connected to one side of the arc-shaped plate, and the other end is rotatably connected to the outside of the cleaning component 2, so that the arc-shaped plate in the baffle 3 can be positioned to surround the cleaning component 2, and the baffle 3 can rotate coaxially with the cleaning component 2. The baffle 3 is connected to a driving component, such as a stepper motor or a gear transmission device, so that the arc-shaped plate is driven to rotate around the cleaning component 2 to switch between a first position and a second position.

[0068] The arc length of the arc plate can be set according to the opening on the inner wall 12 of the cavity to allow the cleaning component 2 to be exposed and cleaned in the first position, and to isolate the cleaning component 2 from the airflow in the second position.

[0069] By using this arc-shaped plate, compared to other solutions, only one drive component is needed to operate it, saving both the drive component and the space required for its placement. Furthermore, because the arc-shaped plate is coaxial with and surrounds the cleaning component 2, compared to baffles 3 of other shapes, the baffle 3 occupies less volume in the air duct in the second position, reducing its impact on airflow and improving the suction and cleaning effect of the air duct.

[0070] In some embodiments, the cleaning component 2 and the baffle 3 are respectively driven to the same driving component, which is configured to switch between forward and reverse rotation and to drive the cleaning component 2 and the baffle 3 to rotate during operation; The cleaning component 2 is connected to the driving component through a one-way transmission structure so that it is driven to rotate when the driving component rotates forward, and is not driven by the driving component when the driving component rotates in reverse. The baffle 3 is connected to the drive component via a transmission structure including a disengagement mechanism, so that it is driven to rotate to the first position when the drive component rotates forward and to rotate to the second position when the drive component rotates in reverse. At the same time, when the baffle 3 rotates to the first position or the second position, the drive component is allowed to disengage from the transmission structure of the baffle 3 and rotate, so as to avoid overloading the drive component.

[0071] In order to save space and reduce costs within the cleaning equipment, the baffle 3 and the cleaning component 2 can be driven to the same drive component, which is configured to drive the baffle 3 from a first position to a second position when rotating forward, and drive the baffle 3 from a second position to a first position when rotating in reverse.

[0072] When the baffle 3 and the cleaning component 2 are connected to the same driving unit, they can be connected by any known transmission structure that allows a single driving unit to be simultaneously connected to both input ends. For example, this could be a gear set including separately meshing bevel gears, or a double-groove pulley on the driving unit, with transmission via two belts. Such transmission structures, where a single driving unit is simultaneously connected to both input ends, are conventional techniques in this field and will not be elaborated upon here.

[0073] When the baffle 3 moves to the second position, the cleaning component 2 is accommodated within the space formed by the baffle 3 and the inner wall 12 of the cavity. If the cleaning component 2 is a roller brush with bristles and / or brush strips, the rotating bristles and / or brush strips will collide with the inner wall 12 of the cavity and the baffle 3, resulting in noise. Therefore, it is necessary to adjust the transmission structure of the cleaning component 2 so that the cleaning component 2 can rotate when the driving component rotates forward and stop rotating when the driving component rotates in reverse to prevent noise generation. To achieve the above objective, the cleaning component 2 can be connected to the driving component through a one-way transmission structure, that is, when the driving component rotates forward, the one-way transmission structure operates normally, and when the driving component rotates in reverse, the one-way transmission structure does not operate. The one-way transmission structure can be any structure capable of achieving the above-mentioned one-way transmission function. For example, it can be configured as a one-way clutch that engages when the drive component rotates forward and disengages when the drive component rotates in reverse; or a ratchet can be provided on the output shaft of the drive component and a corresponding pawl can be provided on the cleaning component 2. The ratchet and pawl engage when the drive component rotates forward and disengage when the drive component rotates in reverse.

[0074] The baffle 3 is connected to the driving component via a transmission structure, which includes a disengagement mechanism. Specifically, the disengagement mechanism can be implemented using existing technologies such as an overrunning clutch mechanism or a friction torque limiting structure, allowing the driving component to disengage from the transmission structure of the baffle 3 when the driving component moves to the first or second position, thereby preventing overload of the driving component.

[0075] Specifically, when the disengagement mechanism is an overrunning clutch mechanism, transmission can be achieved as follows: When the drive component rotates forward, the overrunning clutch is locked, thus transmitting power to rotate the baffle 3 to the first position; when the baffle 3 rotates to its position and is stopped, the overrunning clutch enters the overrunning state, allowing the drive component to continue rotating without pushing the baffle 3, thereby preventing overload of the drive component. Similarly, when the drive component rotates in reverse, the overrunning clutch in the other direction is locked to drive the baffle 3 to rotate to the second position, which also enters the overrunning state upon reaching the second position, allowing the drive component and the baffle 3 to rotate relative to each other.

[0076] When the disengagement mechanism is a friction torque limiting structure composed of a spring-preloaded friction pair, the transmission can be carried out in the following way: when the drive component rotates, the friction torque limiting structure can transmit torque to drive the baffle 3 to rotate; when the baffle 3 rotates to the first position or the second position and is limited, the torque borne by the friction pair increases to exceed the predetermined limit value, the friction surface begins to slip, so that the drive component can continue to rotate while the baffle 3 remains stationary in the first position or the second position, thereby avoiding damage to the drive component or the baffle 3 due to overload.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, a mating seat 13 is provided on the inner wall 12 of the cavity. The mating seat 13 can engage with the extension section 321 on the baffle 3 when the baffle 3 is rotated to the first position, so as to limit the baffle 3 to the first position.

[0078] The mating seat 13 can be configured as any structure that can mate with the extension 321 and form a seal, such as a protrusion fixed to the inner wall 12 of the cavity.

[0079] The cross-section of the mating seat 13 can be designed to fit tightly with the extension 321 in any shape, for example, by providing a groove corresponding to the shape of the extension 321.

[0080] The mating seat 13 can be directly integrally molded into the cavity through injection molding, or installed as a post-installation component by fitting.

[0081] The mating seat 13 allows for the formation of a dedicated part on the inner wall 12 of the cavity that mates with the mating part 32. This facilitates the size design of the baffle 3 and allows the mating seat 13 to limit the position of the baffle 3, so that the baffle 3 abuts against the mating seat 13 when it moves to the first position. Furthermore, the mating seat 13 can be designed with corresponding airtightness to create a larger sealing surface area.

[0082] In some embodiments, the extension 321 of the mating portion 32 can also mate with the mating seat 13. The mating seat 13 is correspondingly provided with a mating structure that fully mates with the mating portion 32. This mating structure can be formed as a groove consistent with the extension, or as a stepped structure. When the mating portion 32 moves to mate with the mating seat 13, since the mating structure in the mating seat 13 has at least two non-parallel surfaces and is formed to fully mate with the extension, a stepped sealing surface can be formed between the mating structure and the extension, thereby achieving a better sealing effect than a single sealing surface.

[0083] In some embodiments, such as Figure 1 and Figure 2As shown, the mating seat 13 is provided with a groove that can mate with the extension section 321. When the baffle 3 is rotated to the first position, the groove mates with the extension section 321 to form a stepped seal between the groove and the extension section 321 while limiting the baffle 3 to the first position.

[0084] The size of the groove on the mating seat 13 is adapted to the extension 321 of the baffle 3. When the baffle 3 rotates to the first position under the action of the driving component, the extension 321 is embedded in the groove and abuts against it. Through this mating structure, on the one hand, the baffle 3 can be limited to the first position to prevent it from continuing to rotate; on the other hand, since the groove has a stepped structure, the extension 321 can abut against multiple stepped surfaces of the groove in sequence when it is embedded, thereby forming a multi-level seal between the contact interfaces. This stepped seal can effectively reduce the impact of the mating gap on airflow leakage, ensure that the baffle 3 forms a good airtightness with the cavity in the first position, maintain the negative pressure stability at the suction port 11, and thus improve cleaning efficiency.

[0085] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes a scraper 4 disposed at the suction port 11, which extends beyond the suction port 11 to guide the waste into the housing 1.

[0086] The scraper 4 is a long and thin strip-shaped component. It is fixedly installed on the outer edge of the suction port 11 and extends outward, thereby forming a guide slope extending from the surface being cleaned into the air duct. It can cooperate with the negative pressure airflow in the air duct and the cleaning component 2 to guide the garbage on the surface being cleaned into the air duct.

[0087] In some embodiments, the cleaning assembly further includes a drive component and a control module for driving the baffle 3. The control module can control the drive component to drive the baffle 3 to move between a first position and a second position, and control the baffle 3 to remain in the first position or the second position. The drive component may be a motor that is pultrusively connected to the baffle 3 in the foregoing embodiments to drive the baffle 3. By using the control module and the drive component, the position of the baffle 3 can be directly controlled, allowing the baffle 3 to be kept in the first position or the second position or moved to any position. Users can choose the position of the baffle 3 to meet their needs.

[0088] In some embodiments, the cleaning component further includes a user terminal, which is signal-connected to the control module and is used to receive user instructions and send them to the control module, and the control module controls the drive component according to the user instructions; and / or: the cleaning component further includes an identification device, which is signal-connected to the control module and is used to identify and determine whether there are filamentous foreign objects on the surface being cleaned, generate a determination result signal and send it to the control module, and the control module controls the drive component according to the determination result signal.

[0089] The user terminal can be any device or component with a human-computer interaction interface capable of sending commands, such as a smartphone, tablet, personal computer, dedicated remote control, smart home panel with touchscreen, or interactive panel installed on a cleaning device that includes cleaning components. These terminals establish connections with the control module via conventional communication methods such as Wi-Fi, Bluetooth, cellular networks, and signal cable connections, converting user input into command signals and sending them to remotely control the movement or stopping of the baffle 3. Through the user terminal, the user can independently control the baffle 3 in the cleaning component to keep it in a specific position, achieving specific effects at each location. For example, baffle 3 can be set to remain in the second position so that when the cleaning equipment is running, baffle 3 always separates the cleaning component 2 from the suction airflow in the air duct, thereby ensuring that no filamentous foreign objects are rolled up on the cleaning component 2, and ensuring that no noise is generated during the cleaning process due to the switching of baffle 3 between the first and second positions; or baffle 3 can be set to remain in the first position so that when the amount of filamentous foreign objects on the surface being cleaned is insufficient to cause problems with the operation of the cleaning component 2, the operation of the cleaning component 2 can be maintained, so that the cleaning component 2 can continuously clean the surface being cleaned.

[0090] The identification device may include any sensor capable of detecting the shape of foreign objects on the surface being cleaned, such as a camera, optical sensor, lidar, or ultrasonic radar. The identification device may also be a combination of any number of the above devices. The sensor's detection direction is pointed towards the surface being cleaned. Simultaneously, the identification device also includes a signal processing unit capable of processing the signals provided by the aforementioned sensors, determining the presence of filamentous foreign objects based on the processed data, and then sending the determination result to the control module, causing the control module to drive the baffle 3 to a designated position according to the determination.

[0091] When the cleaning equipment is running, the sensor continuously detects the debris on the ground and sends the corresponding signal to the signal processing unit. When the signal is normal and the debris on the surface to be cleaned is general debris, the signal processing unit sends a signal to the control module. The control module controls the drive component to put the baffle 3 in the first position, and the cleaning component 2 cleans normally. When an abnormality is detected in the signal, indicating the presence of filamentous foreign objects on the surface to be cleaned, the signal processing unit sends a signal to the control module. The control module controls the drive component to put the baffle 3 in the second position until there are no more filamentous foreign objects on the ground in front.

[0092] When the cleaning components include a user terminal or identification device, the user terminal or identification device operates as described above.

[0093] When the cleaning component includes both a user terminal and an identification device, technicians can pre-configure it so that when the control module receives both the user command from the user terminal and the judgment result signal from the identification device, and the movement directions of the baffle 3 required by the user command and the judgment result signal are contradictory, the control module can selectively execute the command given by one component and ignore the command given by the other component.

[0094] For example, if a user command instructs baffle 3 to move to the first position, and the judgment result signal indicates the presence of filamentous foreign matter on the cleaned surface, requiring baffle 3 to move to the second position, the control module can be configured to execute the user command and ignore the judgment result signal, or to execute the instruction corresponding to the judgment result signal and ignore the user command. In actual use, those skilled in the art can determine, based on actual needs, whether the control module should prioritize executing the user command or the instruction corresponding to the judgment structure signal of the identification device, and configure the control module accordingly to avoid situations where the user command from the user terminal and the judgment structure signal of the identification device contradict each other.

[0095] In some embodiments, the identification device can detect whether there are filamentous foreign objects on the surface being cleaned and send the information to the control module. The control module then sends this information to the user terminal, which in turn sends a signal to the control module according to a preset program, thereby controlling the movement of the baffle 3.

[0096] By simultaneously setting up an identification device and a user terminal, and connecting the identification device signal to the user terminal, the control module ultimately controls the movement of the baffle 3 solely based on the signal output from the user terminal. This allows the user to fully control the movement of the baffle 3 and also choose for it to move automatically according to the condition of the surface being cleaned. Specifically, the preset programs in the user terminal can include an automatic program, a first position program, and a second position program. If the user selects the automatic program, the user terminal automatically controls the baffle 3 according to the signal from the identification device, moving it to the first position when there are no filamentous foreign objects or a small number of filamentous foreign objects on the surface being cleaned, and moving it to the second position when there are filamentous foreign objects or a large number of filamentous foreign objects on the surface being cleaned. If the user selects the first position program, the baffle 3 moves to the first position; if the user selects the second position program, the baffle 3 moves to the second position. The user terminal and identification device configured as described above provide the user with a range of options for selecting the baffle 3, allowing the baffle 3 to move automatically or be manually controlled to move.

[0097] The second aspect of this utility model provides a cleaning device, which includes the above-mentioned cleaning component. The cleaning component is ventilably connected to the fan and dust box in the cleaning device, and cooperates with the fan to suck foreign objects on the surface to be cleaned into the dust box.

[0098] This cleaning device operates when there are few or no filamentous foreign objects on the ground. During normal operation, a negative pressure is generated in the air duct inside its housing 1, drawing in air and dust through the suction port 11. Simultaneously, the baffle 3 is in the first position, with the cleaning component 2 extending and contacting the ground for mechanical cleaning. When the detection device detects filamentous foreign objects, the baffle 3 rotates to the second position, blocking the cleaning component 2 and preventing airflow from contacting it, thus preventing the filamentous foreign objects from becoming entangled. After cleaning is completed or the foreign objects are removed, the baffle 3 automatically switches back to the first position, and the cleaning component 2 continues cleaning.
