Description

TECHNICAL FIELD

[0001] The utility model relates to cleaning equipment technical field especially relates to a cleaning assembly and cleaning equipment. BACKGROUND

[0002] The cleaning surface of the cleaning equipment when performing the cleaning task has diversity, and the dirt levels corresponding to different cleaning surfaces are different. Due to the diversity of the cleaning surface, the existing cleaning equipment can only meet the cleaning requirements of most dirty areas.

[0003] However, when encountering special dirty areas, it cannot achieve effective cleaning effect, such as the part of dirt in the deep part of the carpet cannot be effectively cleaned. INVENTION CONTENTS

[0004] The utility model provides a kind of cleaning assembly and cleaning equipment, to improve the existing cleaning equipment when encountering special dirty areas, it cannot achieve effective cleaning effect.

[0005] Firstly, the utility model provides a kind of cleaning assembly, and the cleaning assembly includes: shielding piece and roll brush assembly, shielding piece is movably installed on the equipment main body of cleaning equipment, shielding piece includes long arm, and side wall is extended along at least one end of long arm, shielding piece surrounds roll brush assembly, shielding piece at least has first position and second position, roll brush assembly includes dust absorption cavity, and ventilation passage is formed between dust absorption cavity and cleaning surface, shielding piece covers part of ventilation passage when being in first position, so that the ventilation area of shielding piece at first position is less than the ventilation area of shielding piece when being in second position;When cleaning surface is carpet, shielding piece is located at first position.

[0006] Among them, the design of shielding piece forms an effective airflow passage by the combination of its long arm and side arm, this structure can concentrate and guide airflow, improve dust absorption efficiency, especially in the case of needing to enhance suction, such as when cleaning carpet, and the shape of shielding piece provides good structural stability, ensures that it can maintain correct position and function during the operation of cleaning equipment, since shielding piece can move between different positions, such as between first position and second position, it can adapt to different cleaning requirements and cleaning surface types.

[0007] In addition, the design of side arm not only helps airflow control, but also can protect internal components of cleaning equipment from external impact and wear to some extent.

[0008] In this way, when cleaning the carpet, by setting the shielding piece in the first position, reducing the ventilation area, the suction force is more concentrated, and the dust and dirt in the deep layer of the carpet can be more effectively removed. Combined with the stirring action of the roller brush assembly, the dirt in the carpet can be more efficiently loosened and sucked, improving the cleaning efficiency. In addition, by adjusting the position of the shielding piece, the shielding piece can significantly improve the cleaning effect, especially when dealing with stubborn dirt and deep dust.

[0009] Optionally, the number of roller brushes in the roller brush assembly is two.

[0010] Among them, the two roller brushes can rotate in different directions to provide multi-angle cleaning, especially when dealing with stubborn dirt and debris, the effect is remarkable. Therefore, the two roller brushes can more effectively handle large particles and debris, prevent clogging and incomplete cleaning problems, and the two roller brushes can also cover a larger cleaning area, reduce cleaning time, and improve overall efficiency. In addition, the design of the two roller brushes can optimize the airflow path, enhance the suction force, improve the dust collection effect, and the two roller brushes can share the workload, reduce the wear of a single roller brush, thereby prolonging the service life of the cleaning device.

[0011] Optionally, with the forward direction of the cleaning device as the front, the shielding piece has a long arm perpendicular to the forward direction, and a first side arm and a second side wall extending in the opposite direction of the forward direction along both ends of the long arm. The long arm is located in front of the roller brush assembly, and the roller brush assembly further includes a roller brush cover plate for mounting on the bottom of the suction chamber. The cleaning assembly further includes a scraper mounted on the device main body and located at a position behind the roller brush assembly. When the shielding piece is in the first position, the scraper and the shielding piece surround the roller brush cover plate from all around to cover part of the ventilation channel.

[0012] In this way, when the shielding piece is in the first position, the scraper and the shielding piece jointly surround the roller brush cover plate and partially cover the ventilation channel. This design can concentrate the suction force around the roller brush assembly, improve the dust collection efficiency, and further concentrate and guide the dirt to the suction chamber, ensuring that the suction force is concentrated and efficient, reducing the cleaning dead angle, and optimizing the airflow path, reducing the loss of airflow. In addition, the scraper further cleans the cleaning surface after the cleaning device passes, reducing the possibility of residue and protecting the cleanliness and integrity of the cleaning surface. This component arrangement ensures that the cleaning device can achieve ideal cleaning effect in a single pass, reducing the need for repeated cleaning and improving overall efficiency.

[0013] Further, through the enhanced cleaning effect and efficiency, better cleaning results can be achieved in a shorter time, improving the user's use satisfaction.

[0014] Optionally, the scraper has a third position in contact with the cleaning surface and a fourth position away from the cleaning surface.

[0015] In this way, the scraper can effectively remove stubborn dirt and residues on the cleaning surface when it is in the third position, ensuring that the cleaned surface is cleaner, and the mobility of the scraper allows the cleaning device to adjust its position as needed, thereby optimizing energy consumption and efficiency during cleaning. Raising the scraper to the fourth position when it is not needed can reduce wear and tear on the scraper, thereby extending its service life. In addition, the design of the scraper allows the cleaning device to adapt to different types of cleaning surfaces and dirt conditions, thereby providing more personalized and efficient cleaning solutions.

[0016] Optionally, the cleaning assembly further comprises a U-shaped cavity in the device body, the U-shaped cavity is used to accommodate the shielding piece, and the U-shaped cavity comprises a front part and two side walls, which surround the shielding piece. When the shielding piece is in the first position, the shielding piece protrudes out of the U-shaped cavity.

[0017] Therefore, the design of the U-shaped cavity helps to concentrate airflow and dirt, making it more effective to be sucked into the dust suction cavity. The protruding position of the shielding piece further enhances this effect by increasing the suction force to improve cleaning efficiency. In addition, the U-shaped cavity provides a structured space to accommodate and guide the roller brush assembly and the shielding piece. This design simplifies the internal structure of the cleaning device, reduces airflow and dirt loss, and optimizes airflow path and suction force to enable the cleaning device to achieve higher efficiency in different cleaning scenarios and reduce energy consumption.

[0018] It can be understood that the design of the shielding piece allows it to move between the first position and the second position. When the shielding piece is in the first position, it partially covers the ventilation channel, thereby enhancing the suction force. This enhanced suction force helps to more effectively remove deep-seated dirt, especially on surfaces such as carpets that require powerful suction. The structure of the U-shaped cavity around the roller brush assembly forms a space that concentrates airflow, and by optimizing the airflow path, the cleaning device can more effectively guide dirt into the dust suction cavity, improving cleaning efficiency.

[0019] Therefore, by adjusting the position of the shielding piece, the cleaning device can optimize the ventilation area in different cleaning scenarios. This flexibility allows the cleaning device to enhance suction force when needed and reduce energy consumption when not needed, thereby optimizing airflow and suction force to enable the cleaning device to achieve higher energy efficiency in different operating modes and reduce unnecessary energy consumption. In addition, the design of the shielding piece and the U-shaped cavity simplifies the internal structure of the cleaning device, reduces airflow and dirt loss, and enhances the overall reliability of the cleaning device.

[0020] Optionally, the cleaning assembly further comprises a drive mechanism, the shielding piece comprises a connecting part and a shielding part, the connecting part is connected with the drive mechanism, and the shielding part is fixed with the connecting part. The shielding part is an arc-shaped shielding part, or the shielding part is a planar shielding part.

[0021] Therefore, the shielding part of different shapes such as arc or plane can be designed to optimize the airflow path and suction force according to the specific cleaning needs, thereby improving the cleaning efficiency. The selection of arc or plane shielding part can be determined based on the cleaning scene and needs. For example, the arc design can be used for scenes that require more precise airflow control, while the plane design is suitable for situations that require large-area shielding.

[0022] Optionally, the thickness of the connecting part is greater than the thickness of the shielding part.

[0023] In this way, the thicker design of the connecting part increases its fixing ability, ensuring that the shielding part remains stable during the operation of the cleaning device and does not loosen due to vibration or impact. The thinner design of the shielding part improves the deformation ability, allowing the shielding part to more easily adapt to changes in the cleaning surface during the cleaning process, thereby improving the applicability of the cleaning device and achieving better cleaning results.

[0024] In addition, the thinner design of the shielding part allows the shielding part to closely fit the cleaning surface when in the first position, reducing air leakage and improving the effectiveness of the suction force, thereby enhancing the cleaning effect. Moreover, the thinner shielding part can also reduce friction and wear on the cleaning surface, protecting the material and appearance of the cleaning surface.

[0025] Optionally, the connecting part includes a soft connecting part and a hard connecting part connected to the soft connecting part, the soft connecting part being located closer to the direction of the roller brush assembly, and the hard connecting part being located away from the direction of the roller brush assembly.

[0026] Therefore, the flexible material of the soft connecting part can closely fit the roller brush assembly, reducing air leakage and improving the concentration of the suction force and the cleaning effect. Moreover, the soft connecting part can adapt to the dynamic movement of the roller brush assembly, reducing wear and damage caused by vibration or movement. The hard connecting part provides necessary support and stability, ensuring that the cleaning device remains structurally intact during operation and is less prone to deformation. In this way, by combining flexible and rigid materials, the connecting part can provide good sealing while maintaining durability and long service life. Moreover, the combination of soft and hard materials makes the connecting part easier to maintain and clean, reducing the operational burden on the user.

[0027] Optionally, with the forward direction of the cleaning device being forward, the shielding part has a long arm perpendicular to the forward direction, and a first side arm and a second side wall extending in the opposite direction of the forward direction from both ends of the long arm. The long arm is located in front of the roller brush assembly, and has a force application point at any position of the long arm. The bottom end of the first side arm and the second side wall each has a hinge part, and the cleaning assembly further includes an elastic reset part connected to the hinge part.

[0028] By applying force to the force application point, the shielding part is rotated in the first direction based on the hinge part to place the shielding part in the first position.

[0029] By withdrawing the force applied to the force application point, the elastic return member and the hinge portion jointly drive the shielding member to rotate in a second direction, so that the shielding member is in a second position; the first direction is opposite to the second direction.

[0030] It can be understood that the hinge portion provides a stable rotation axis, ensuring that the shielding member remains stable during adjustment and does not loosen or deviate, in addition, by applying a force to the force application point or withdrawing the force applied to the force application point, the position of the shielding member is adjusted, which can optimize the airflow path and the distribution of suction force, improve the cleaning efficiency, especially when dealing with different types of cleaning surfaces, and based on the above structure design, the shielding member part structure is detachable, when the cleaning equipment needs to be repaired, the partially detached design makes it easier for technicians to access the internal components of the cleaning equipment, simplifying the repair process.

[0031] Optionally, the roller brush assembly has a fifth position in contact with the cleaning surface, and a sixth position away from the cleaning surface.

[0032] The cleaning assembly further comprises a driving mechanism for driving the shielding member to move between the first position and the second position, and / or the driving mechanism is used to drive the roller brush assembly to move between the fifth position and the sixth position, and the driving mechanism is a single motor.

[0033] Therefore, by using a single driving mechanism to drive the positions of the shielding member and the roller brush assembly, the need for manual operation by the user is reduced, so that the cleaning equipment can automatically adjust the positions of its components according to different cleaning needs, thereby achieving ideal cleaning effect on different types of cleaning surfaces, in addition, using the same driving mechanism to control the movement of multiple components reduces the number of independent driving components required in the cleaning equipment, which not only simplifies the mechanical design of the cleaning equipment, but also reduces the complexity of manufacturing and assembly, and the single driving mechanism can ensure the coordination and consistency of the movement of the shielding member and the roller brush assembly.

[0034] Optionally, when the shielding member is in the first position, the shielding member is in contact with the cleaning surface.

[0035] Therefore, the shielding member directly contacting the surface of the carpet can apply additional physical pressure, which helps to loosen and extract deep dirt, and this physical action combined with enhanced suction force can significantly improve the cleaning effect on the carpet, and by optimizing the position of the shielding member, the cleaning equipment can improve the cleaning efficiency without increasing additional energy consumption, which makes the cleaning equipment more efficient when dealing with complex surfaces such as carpets.

[0036] Optionally, the shielding member also has a seventh position, when the shielding member is in the seventh position, the shielding member is spaced apart from the cleaning surface by a predetermined distance; when the cleaning surface is not a carpet, the shielding member is in the seventh position, and the ventilation area of the shielding member in the seventh position is less than or equal to the ventilation area of the shielding member in the first position.

[0037] In this way, the spacing between the shield and the cleaning surface for non-carpeted surfaces can reduce unnecessary friction and wear, thereby prolonging the service life of the cleaning assembly, and this arrangement can also reduce the energy consumption of the cleaning device, as the power required for physical contact is reduced, in addition, by providing a choice of multiple seventh positions, the cleaning device can flexibly adapt to different types of non-carpeted surfaces, providing more personalized cleaning solutions, such as by adjusting the distance between the shield and the cleaning surface, the cleaning device can achieve the ideal combination of airflow and suction on non-carpeted surfaces, thereby improving cleaning efficiency.

[0038] Optionally, the roller brush assembly has a fifth position in contact with the cleaning surface, and a sixth position away from the cleaning surface;

[0039] The cleaning assembly further comprises a driving mechanism for driving the shield to move between the seventh position and the second position, and / or the driving mechanism is used to drive the roller brush assembly to move between the fifth position and the sixth position, and the driving mechanism is a single motor.

[0040] In this way, by dynamically adjusting the positions of the shield and the roller brush assembly through a single driving mechanism, the cleaning device can provide more powerful and effective cleaning on non-carpeted surfaces, and this flexibility ensures effective extraction of stubborn dirt or granular dirt, especially under different cleaning needs, the driving mechanism can quickly adjust the positions of the components to optimize the energy consumption and cleaning efficiency of the cleaning device.

[0041] Therefore, by driving the positions of the shield and the roller brush assembly through a single driving mechanism, the need for manual operation by the user is reduced, in addition, using the same driving mechanism to drive the movement of the shield and the roller brush assembly reduces the number of independent driving components required in the cleaning device, simplifies the mechanical design of the cleaning device, reduces the complexity of manufacturing and assembly, and also ensures the consistency of the coordinated movement of the shield and the roller brush assembly.

[0042] Optionally, the cleaning assembly further comprises a limiting member for limiting the position of the shield to move between the first position and the second position.

[0043] Therefore, by limiting the movement range of the shield, the limiting member provides the necessary stability to prevent accidental movement or vibration of the shield during operation of the cleaning device, in addition, the limiting member prevents excessive movement of the shield, which can also avoid potential damage to internal components of the cleaning device and the cleaning surface.

[0044] In a second aspect, the utility model provides a kind of cleaning assembly, and cleaning assembly includes: shielding piece and roll brush assembly, shielding piece is movably installed on the equipment main body of cleaning equipment, shielding piece includes long arm, and side wall is extended along at least one end of long arm, shielding piece surrounds roll brush assembly, shielding piece at least has seventh position and second position, roll brush assembly includes dust absorption cavity, and ventilation passage is formed between dust absorption cavity and cleaning surface, shielding piece covers part ventilation passage when in seventh position, to make the ventilation area of shielding piece at seventh position less than the ventilation area of shielding piece when in second position;When cleaning surface is non-carpet, shielding piece is located in seventh position.

[0045] It needs to be explained that, above-mentioned for non-carpet scene, the specific implementation principle and effect of structural design of cleaning assembly are similar with the implementation principle and effect of structural design of cleaning assembly in the first aspect, similar part can refer to the description of the first aspect, and here is not repeated, and the different place of two is: when shielding piece is located in seventh position, part ventilation passage can be covered, and ventilation area is reduced, this design makes suction more concentrated, can more effectively remove dust and small particles on non-carpet surface, and concentrated suction is also helpful to more quickly suck surface dirt and debris for non-carpet surface, such as hard floor or ceramic tile, improves cleaning efficiency, reduces cleaning time.

[0046] It can be understood that, by adjusting the position of shielding piece, cleaning equipment can flexibly adapt to different types of cleaning surface, seventh position is suitable for non-carpet surface with heavy dust, breadcrumb, biscuit crumbs, cereal and other small particles, and second position can be more suitable for non-carpet cleaning with stone, broken plastic toys, packaging material fragments and other large particle dirt, and this flexibility ensures the effectiveness of cleaning equipment in multiple environments.

[0048] In this way, the combination of the shield and the squeegee, by forming a target space around the roller brush assembly, can increase the sealing area, and thus the dirt is more effectively concentrated and guided to the suction cavity, ensuring the concentration of suction force and high efficiency, reducing the cleaning dead angle, and the airflow path is optimized, reducing the loss of airflow. This design can significantly improve the cleaning efficiency, and the squeegee further cleans the cleaning surface after the cleaning device passes, reducing the possibility of residue and protecting the cleanliness and integrity of the cleaning surface. This assembly arrangement ensures that the cleaning device can achieve the desired cleaning effect in a single pass, reducing the need for repeated cleaning and improving overall efficiency.

[0049] Further, through enhanced cleaning effect and efficiency, better cleaning results can be achieved in a shorter time, improving user satisfaction.

[0050] Optionally, the squeegee has a third position in contact with the cleaning surface and a fourth position away from the cleaning surface.

[0051] In this way, the squeegee can effectively remove stubborn dirt and residue on the cleaning surface when in the third position, ensuring that the cleaned cleaning surface is cleaner. Moreover, the mobility of the squeegee allows the cleaning device to adjust its position as needed, thereby optimizing energy consumption and efficiency during cleaning. Raising the squeegee to the fourth position when it is not needed can reduce wear and tear on the squeegee, thereby extending its service life. In addition, the design of the squeegee allows the cleaning device to adapt to different types of cleaning surfaces and dirt conditions, thereby providing more personalized and efficient cleaning solutions.

[0052] Optionally, the cleaning assembly further includes a U-shaped cavity in the device body, the U-shaped cavity being configured to accommodate the shield, the U-shaped cavity including a front portion and two side walls that surround the shield, and the shield protruding from the U-shaped cavity when the shield is in the seventh position.

[0053] Therefore, the design of the U-shaped cavity helps to concentrate airflow and dirt, making it more effectively sucked into the suction cavity. The protruding position of the shield further enhances this effect by increasing the suction force to improve cleaning efficiency. Moreover, the U-shaped cavity provides a structured space to accommodate and guide the roller brush assembly and the shield. This design simplifies the internal structure of the cleaning device, reduces airflow and dirt loss, and optimizes airflow path and suction force to enable the cleaning device to achieve higher efficiency in different cleaning scenarios and reduce energy consumption.

[0054] It can be understood that the design of the shielding piece allows it to move between the seventh position and the second position, in the seventh position, the shielding piece partially covers the ventilation channel, thereby enhancing the suction force, and this enhanced suction force helps to more effectively remove dirt, especially for surfaces that require strong suction, the shielding piece is located in the structure of the U-shaped cavity around the roller brush assembly, forming a space for concentrated airflow, by optimizing the airflow path, the cleaning device can more effectively guide the dirt into the suction chamber, improving cleaning efficiency.

[0055] Therefore, by adjusting the position of the shielding piece, the cleaning device can optimize the ventilation area in different cleaning scenarios, this flexibility allows the cleaning device to enhance the suction force when needed, and reduce energy consumption when not needed, thereby optimizing the airflow and suction force, the cleaning device can achieve higher energy efficiency in different operating modes, reduce unnecessary energy consumption, in addition, the design of the shielding piece and the U-shaped cavity simplifies the internal structure of the cleaning device, reduces the loss of airflow and dirt, and enhances the overall reliability of the cleaning device.

[0056] Optionally, the roller brush assembly has a fifth position in contact with the cleaning surface, and a sixth position away from the cleaning surface.

[0057] The cleaning assembly further comprises a driving mechanism for driving the shielding piece to move between the seventh position and the second position, and / or the driving mechanism is used to drive the roller brush assembly to move between the fifth position and the sixth position, and the driving mechanism is a single motor.

[0061] Therefore, the shielding part of different shapes such as arc or plane can be designed to optimize the airflow path and suction force according to the specific cleaning needs, thereby improving the cleaning efficiency. The arc or plane shielding part can be selected based on the cleaning scene and needs. For example, the arc design can be used for scenes that require more precise airflow control, while the plane design is suitable for situations that require large-area shielding.

[0062] Optionally, the connecting part includes a soft connecting part and a hard connecting part connected to the soft connecting part, the soft connecting part is located close to the direction of the roller brush assembly, and the hard connecting part is located away from the direction of the roller brush assembly.

[0090] To solve the above problems, the utility model provides a kind of cleaning assembly, and cleaning assembly includes: shelter and roll brush assembly, shelter is designed to include long arm, and the side wall extending at least one end along long arm, and design shelter around roll brush assembly, with at least two positions, first position and second position, when first position, shelter partially covers ventilation passage, to reduce ventilation area, this design can enhance suction concentration, so that dust suction chamber can more effectively suck dirty of carpet deep place, roll brush assembly is loosened by agitating carpet fiber, so that it is more easily sucked into dust suction chamber, in combination with the adjustment of shelter, roll brush assembly can play a greater role in carpet cleaning, so that, when carpet cleaning, shelter is adjusted to first position, can reduce ventilation area, so that suction is more concentrated, this design can effectively increase the adsorption capacity of deep dirt of carpet, solve the problem that dirty is difficult to clean in carpet deep place, and by the stirring effect of roll brush assembly, in combination with enhanced suction, can more efficiently remove stubborn dirt in carpet, this combined design improves overall cleaning efficiency.

[0091] In addition, since the shelter has at least a first position and a second position, the size of the ventilation passage can be dynamically changed by adjusting the position of the shelter, thereby optimizing the distribution of suction and adapting to different types of cleaning surfaces and degrees of dirt.

[0092] It should be noted that, in the utility model, the carpet refers to a cleaning area that includes at least various types of fiber distribution. The surface of the carpet is usually soft and has a certain thickness and nap, which makes dirt and dust easy to embed therein. For example, the area distributed by the cleaning surface composed of wool, nylon, polyester and the like. Alternatively, the carpet can specifically refer to a cleaning area that requires stronger suction and physical agitation capacity to extract deep dirt and dust.

[0093] For example, Figure 1 An application scenario diagram is provided for the utility model, as Figure 1 As shown, the application scenario can be applied to the cleaning scenario of the carpet 200. Taking the cleaning device 100 as a sweeping robot for example, the shelter 11 is installed on the sweeping robot. When the sweeping robot cleans the carpet 200, the shelter 11 can be controlled to be in the first position to clean the carpet. When the shelter 11 is in the first position, the shelter 11 partially covers the ventilation passage. This design increases the negative pressure of the dust suction chamber, thereby improving the suction, and the sweeping robot can extract deep-embedded dirt and debris to more effectively remove these hard-to-reach dirt, ensuring deep cleaning of the carpet.

[0094] And the enhanced suction force and optimized airflow path can enable the robot vacuum cleaner to work more efficiently when cleaning carpets, reducing the need for repeated cleaning, thereby improving overall cleaning efficiency. In this way, by providing stronger cleaning power when cleaning carpets, the robot vacuum cleaner can complete the cleaning task in a shorter time, which not only saves time but also reduces battery consumption, improving the energy efficiency of the robot vacuum cleaner.

[0095] In addition, the enhanced suction force can also reduce the need for repeated cleaning of the carpet, thereby reducing physical wear and tear on the carpet fibers and extending the service life of the carpet.

[0096] It should be noted that the type of cleaning device 100 is not specifically limited, and the cleaning device 100 includes any automatic cleaning device with cleaning function such as a robot vacuum cleaner, a robot mop, a robot washer, a robot sweeper and mop, etc.

[0097] Optionally, Figure 2 A partial structure diagram of a cleaning assembly provided by the present utility model is shown in FIG. 1. Figure 2 As shown in FIG. 1, the cleaning assembly 102 includes a shielding member 11 and a roller brush assembly 12. The shielding member 11 is movably mounted on a device main body 101 of the cleaning device 100. The shielding member 11 includes a long arm and a side wall extending along at least one end of the long arm. For example, the shielding member 11 is designed in a "U" shape or an "L" shape. Taking the shielding member 11 as a U-shaped member as an example, the shielding member 11 has a long arm and two side walls extending along both ends of the long arm. Taking the shielding member 11 as an L-shaped member as an example, the shielding member 11 has a long arm and one side wall extending along any one end of the long arm. The present utility model does not limit the specific shape of the shielding member 11.

[0098] The shielding member 11 surrounds the roller brush assembly 12. The shielding member 11 has at least a first position and a second position. The roller brush assembly 12 includes a dust collection cavity 13. A ventilation passage 14 is formed between the dust collection cavity 13 and a cleaning surface. When the shielding member 11 is in the first position, it covers part of the ventilation passage 14, so that the ventilation area of the shielding member 11 at the first position is smaller than that at the second position. When the cleaning surface is a carpet, the shielding member 11 is located at the first position.

[0099] In the first position, the shielding member 11 partially covers the ventilation passage 14. By reducing the ventilation area of the ventilation passage, the negative pressure in the dust collection cavity 13 is increased, thereby enhancing the concentration of suction force. This enhanced suction force is particularly suitable for cleaning surfaces such as carpets that require deep cleaning.

[0100] For example, Figure 3 A bottom structure diagram of a cleaning device provided by the present utility model is shown in FIG. 2. Figure 3As shown, the cleaning device 100 comprises a device body 101 and a cleaning assembly 102, the cleaning assembly 102 has a structure as shown in the figure, wherein, as shown in the figure, with the advancing direction of the cleaning device 100 as the front, the shielding piece 11 has a long arm 113 substantially perpendicular to the advancing direction, and a first side arm 114 and a second side wall 115 extending in the opposite direction of the advancing direction along the two ends of the long arm. Figure 2 As shown in the figure, with the advancing direction of the cleaning device 100 as the front, the shielding piece 11 has a long arm 113 substantially perpendicular to the advancing direction, and a first side arm 114 and a second side wall 115 extending in the opposite direction of the advancing direction along the two ends of the long arm. Figure 4 As shown in the figure, with the advancing direction of the cleaning device 100 as the front, the shielding piece 11 has a long arm 113 substantially perpendicular to the advancing direction, and a first side arm 114 and a second side wall 115 extending in the opposite direction of the advancing direction along the two ends of the long arm.

[0101] Optionally, Figure 4 A bottom structure schematic diagram of a cleaning assembly provided by the utility model is shown in the figure, wherein, as shown in the figure, the long arm 113 is located in front of the rolling brush assembly 12, and the long arm 113 has a force point 116 at any position thereof, and the bottom ends of the first side arm 114 and the second side wall 115 each have a hinged part 117, and the cleaning assembly 102 further comprises an elastic reset piece (not shown in the figure) connected with the hinged part 117. Figure 4 As shown in the figure, with the advancing direction of the cleaning device 100 as the front, the shielding piece 11 has a long arm 113 substantially perpendicular to the advancing direction, and a first side arm 114 and a second side wall 115 extending in the opposite direction of the advancing direction along the two ends of the long arm.

[0102] By applying force to the force point 116, the shielding piece 11 is rotated in the first direction based on the hinged part 117, so that the shielding piece 11 is in the first position.

[0103] By withdrawing the force applied to the force point 116, the shielding piece 11 is rotated in the second direction under the joint action of the elastic reset piece and the hinged part 117, so that the shielding piece 11 is in the second position; the first direction is opposite to the second direction.

[0104] Optionally, the force of the driving rod is provided by a motor, and the utility model does not make specific limitation on this.

[0105] The hinged part 117 is located at the bottom end of the first side arm and the second side wall, allowing the shielding piece 11 to rotate around the hinged part 117.

[0106] Optionally, taking a torsional spring as an example of the elastic reset piece, after withdrawing the force applied to the force point 116, the torsional spring can rebound based on the elastic force of the torsional spring, and then under the joint action of the hinged part 117 and the torsional spring, the shielding piece 11 is rotated in the second direction, so that the shielding piece 11 is in the second position. The utility model does not make specific limitation on how to withdraw the force applied to the force point 116 and the way of adjusting the shielding piece 11 to the second position. The above is only an example for illustration. Optionally, the elastic reset piece can also be a compression spring, a tensile spring, a wave spring, a torsion bar, etc. The utility model does not make specific limitation on the structure of the elastic reset piece.

[0107] It can be understood that the hinge part 117 provides a stable rotation axis, ensuring that the shielding part 11 remains stable during adjustment and does not loosen or deviate, and by applying force to the force application point 116 or withdrawing the force applied to the force application point 116, the position of the shielding part 11 is adjusted, the airflow path and suction force distribution can be optimized, and the cleaning efficiency is improved, especially when dealing with different types of cleaning surfaces, and based on the above structure design, the shielding part 11 part structure can be disassembled, when the cleaning equipment 100 needs to be repaired, the partially disassembled design makes it easier for technicians to access the internal components of the cleaning equipment 100, simplifying the repair process.

[0108] It should be noted that the vertical arrangement of the long arm 113 helps to effectively block and guide the airflow when the cleaning equipment advances, so that the suction force is more concentrated, and the first side arm 114 and the second side wall 115 extend from the two ends of the long arm 113 in the opposite direction of the advancing direction, this design makes the opening part of the shielding part 11 face the rear of the cleaning equipment 100, and the extension of the first side arm 114 and the second side wall 115 provides a closed or semi-closed structure, which helps to form an effective ventilation channel, which can help to guide and concentrate the airflow, thereby improving the dust collection efficiency.

[0109] It should be noted that the specific shape of the shielding part 11 is not specifically limited, especially the extension length of the side arm, for example, the extension length of the side arm at both ends of the long arm can be equal or not equal, and the shielding part 11 can also be similar to the shape of "U".

[0110] Therefore, the design of the shielding part 11 forms an effective airflow channel through the combination of its long arm and side arm, and this structure can concentrate and guide the airflow, improve the dust collection efficiency, especially in the case of needing to enhance the suction force, such as when cleaning carpets, and the shape of the shielding part 11 provides good structural stability, ensuring that it can maintain the correct position and function during the operation of the cleaning equipment 100, and since the shielding part 11 can move between different positions, such as between the first position and the second position, it can adapt to different cleaning needs and types of cleaning surfaces.

[0111] In addition, the design of the side arm not only helps to control the airflow, but also to a certain extent, protects the internal components of the cleaning equipment 100 from external impact and wear.

[0112] In this way, when cleaning carpets, by setting the shielding part 11 to be in the first position, the ventilation area is reduced, the suction force is more concentrated, and the dust and dirt in the deep layer of the carpet can be more effectively removed, and in combination with the stirring action of the roller brush assembly 12, the dirt in the carpet can be more efficiently loosened and sucked, improving the cleaning efficiency, and in addition, by adjusting the position of the shielding part, the shielding part can significantly improve the cleaning effect, especially when dealing with stubborn dirt and deep dust.

[0113] Optionally, the number of roller brushes in roller brush assembly 12 is two.

[0114] The two roller brushes can rotate in different directions, providing multi-angle cleaning, which is particularly effective when dealing with stubborn dirt and debris. Therefore, the two roller brushes can more effectively handle large particles and debris, preventing clogging and incomplete cleaning. The two roller brushes can also cover a larger cleaning area, reducing cleaning time and improving overall efficiency. In addition, the design of the two roller brushes can optimize the airflow path, enhance suction power, improve dust collection effect, and the two roller brushes can share the workload, reducing the wear of individual roller brushes, thereby extending the service life of the cleaning equipment.

[0115] It should be noted that the number of rollers in the roller brush assembly 12 can be set to more or only one. This utility model does not make a specific limitation on the number of rollers that can be set in the roller brush assembly 12.

[0116] Optional, such as Figure 3 As shown, the cleaning component 102, in addition to having Figure 2 In addition to the structure shown, the cleaning assembly 102 also includes a scraper 17, exemplarily. Figure 5 This is a structural schematic diagram of a shielding component and a scraper provided by this utility model, as shown below. Figure 5 As shown, with the forward direction of the cleaning device 100 as the front, the long arm 113 is located in front of the roller brush assembly 12. The roller brush assembly 12 also includes a roller brush cover plate 121 for installation at the bottom of the dust suction chamber 13. The scraper 17 is installed on the device body 101 and is located behind the roller brush assembly 12. When the shielding member 11 is in the first position, the scraper 17 and the shielding member 11 surround the roller brush cover plate 121 from all sides to cover part of the ventilation channel 14.

[0117] The shield 11 and the scraper 17 together surround the roller brush cover 121 to partially cover the ventilation channel 14, thereby forming a target space. This target space helps to concentrate and guide dirt into the suction chamber. This design also helps to optimize the airflow path and ensure that the suction is concentrated in the area where the roller brush assembly 12 is located. Through this arrangement, the airflow is effectively guided into the roller brush assembly 12, and under the agitation of the roller brush, dust and dirt are loosened and sucked into the suction chamber 13. In addition, the scraper 17 can also be used to clean the residue behind the roller brush to ensure the cleaning effect.

[0118] It is understood that the shielding member 11 and the scraper 17 together form a target space around the roller brush cover 121, which can be closed or semi-closed. This utility model does not specifically limit the closure of the target space.

[0119] In this way, when the shield 11 is in the first position, the squeegee 17 and the shield 11 jointly surround the roller brush cover plate 121, partially covering the air passage 14, which can concentrate the suction force near the roller brush assembly 12, improve the dust collection efficiency, and further effectively concentrate and guide the dirt to the dust collection cavity 13, ensuring the concentration and efficiency of the suction force, reducing the cleaning dead angle, optimizing the airflow path, reducing the loss of airflow, and the squeegee 17 further cleans the cleaning surface after the cleaning device 100 passes, reducing the possibility of residue, protecting the cleanliness and integrity of the cleaning surface, and ensuring that the cleaning device 100 can achieve the desired cleaning effect in a single pass, reducing the need for repeated cleaning and improving overall efficiency.

[0120] Further, through the enhanced cleaning effect and efficiency, better cleaning results can be achieved in a shorter time, improving user satisfaction.

[0121] Optionally, the squeegee 17 has a third position in contact with the cleaning surface and a fourth position away from the cleaning surface.

[0122] In the third position, the squeegee 17 is in direct contact with the cleaning surface and can be used to scrape off stubborn dirt and residue on the cleaning surface during cleaning, and in the fourth position, the squeegee 17 is away from the cleaning surface to reduce friction on the cleaning surface. The distance of the squeegee 17 away from the cleaning surface is not specifically limited by the present application, and the fourth position corresponds to the lifting position of the squeegee 17, which can be set based on actual application scenarios or product performance.

[0123] For example, Figure 6 A structure diagram of a squeegee in a third position and a fourth position is provided in the present application, as shown in Figure 6 A, the squeegee 17 is in the fourth position, as shown in Figure 6 B, the squeegee 17 is in the third position, and the shield 11 is in the second position.

[0124] In this way, the squeegee 17 in the third position can effectively scrape off stubborn dirt and residue on the cleaning surface, ensuring that the cleaned cleaning surface is cleaner, and the mobility of the squeegee 17 allows the cleaning device 100 to adjust its position as needed, thereby optimizing energy consumption and efficiency during cleaning. In the case where the squeegee 17 is not needed, lifting it to the fourth position can reduce wear and tear on the squeegee 17, thereby prolonging its service life. In addition, the design of the squeegee 17 allows the cleaning device 100 to adapt to different types of cleaning surfaces and dirt conditions, thereby providing more personalized and efficient cleaning solutions.

[0125] Optionally, as Figure 3As shown, the cleaning assembly 102 also has a side brush assembly 15, the side brush assembly 15 has an eighth position in contact with the cleaning surface and a ninth position away from the cleaning surface, the eighth position corresponds to the ground position, and the ninth position corresponds to the raised position.

[0126] Wherein, at the eighth position, the side brush assembly 15 is in direct contact with the cleaning surface, the bristles of the side brush can penetrate into the gaps and edge areas of the cleaning surface, sweep away accumulated dust and debris, and guide them into the range of the roller brush assembly 12 and the suction chamber 13.

[0127] At the ninth position, the side brush assembly 15 is away from the cleaning surface, raising the side brush can reduce unnecessary wear and tear, such as raising the side brush assembly 15 when cleaning carpets, which can prevent the side brush from tangling.

[0128] Optionally, as Figure 5 As shown, the cleaning assembly 102 also includes a U-shaped cavity 18 in the device body 101, the U-shaped cavity 18 is used to accommodate the shield 11, the U-shaped cavity 18 includes a front part and two side walls, which surround the shield 11, and the shield 11 protrudes from the U-shaped cavity 18 when the shield 11 is in the first position.

[0129] It can be understood that the shield 11 is wrapped around the roller brush assembly 12 in a U-shaped half.

[0130] Wherein, the U-shaped cavity 18 is composed of a front part and two side walls, which surround the shield 11, the shield 11 is installed in the U-shaped cavity 18 and can move therein, this structure forms a semi-enclosed space, which helps to concentrate and guide airflow and dirt.

[0131] When the shield 11 is in the first position, the shield 11 protrudes from the U-shaped cavity 18, which means that the shield 11 partially extends out of the opening of the U-shaped cavity, thereby adjusting the size of the ventilation area of the ventilation channel 14, in the first position, the shield 11 partially covers the ventilation channel by protruding from the U-shaped cavity 18, this arrangement can enhance the negative pressure of the suction chamber 13, thereby increasing the suction force.

[0132] Therefore, the design of the U-shaped cavity 18 helps to concentrate airflow and dirt, making them more effectively sucked into the suction chamber 13, the protruding position of the shield 11 further enhances this effect by increasing the suction force to improve cleaning efficiency, and the U-shaped cavity 18 provides a structured space to accommodate and guide the roller brush assembly 12 and the shield 11, this design simplifies the internal structure of the cleaning device 100, reduces the loss of airflow and dirt, and optimizes the airflow path and suction force, so that the cleaning device 100 can achieve higher efficiency in different cleaning scenarios and reduce energy consumption.

[0133] It can be understood that the design of the shielding piece 11 allows it to move between the first position and the second position, in the first position, the shielding piece 11 partially covers the ventilation channel 14, thereby enhancing the suction force, which helps to more effectively remove deep dirt, especially on surfaces such as carpets that require strong suction, the shielding piece 11 is located in the structure of the U-shaped cavity 18 around the roller brush assembly 12, forming a space for concentrated airflow, by optimizing the airflow path, the cleaning device 100 can more effectively guide the dirt into the suction cavity 13, improving the cleaning efficiency.

[0134] Therefore, by adjusting the position of the shielding piece 11, the cleaning device 100 can optimize the ventilation area in different cleaning scenarios, this flexibility allows the cleaning device 100 to enhance the suction force when needed, and reduce energy consumption when not needed, thereby optimizing the airflow and suction force, the cleaning device 100 can achieve higher energy efficiency in different operating modes, reduce unnecessary energy consumption, in addition, the design of the shielding piece 11 and the U-shaped cavity 18 simplifies the internal structure of the cleaning device 100, reduces the loss of airflow and dirt, and enhances the overall reliability of the cleaning device 100.

[0135] Optionally, Figure 7 The shielding piece structure schematic diagram provided by the utility model is shown in the figure, Figure 7 The shielding piece 11 includes a connecting part 111 and a shielding part 112, the connecting part 111 is connected with the driving mechanism 16, and the shielding part 112 is fixed with the connecting part 111, Figure 7 As shown in A, the shielding part 112 can be an arc-shaped shielding part, or, Figure 7 As shown in B, the shielding part 112 can be a planar shielding part.

[0136] Among them, the connecting part 111 is the connecting point of the shielding piece 11 and the driving mechanism 16, which is responsible for transmitting the movement of the driving mechanism to the shielding part 112, thereby realizing the movement of the shielding piece, the shielding part 112 can be designed in different shapes to meet different functional requirements, such as, Figure 7 As shown in A, the arc-shaped shielding part can better wrap around the roller brush assembly 12, thereby guiding the airflow, reducing airflow resistance, and optimizing the dust collection effect, such as, Figure 7 As shown in B, the planar shielding part can provide a simple and direct shielding effect, which corresponds to a larger area shielding.

[0137] It can be understood that through the connecting part 111, the driving mechanism 16 can accurately drive the position and angle of the shielding part 112, thereby adjusting the ventilation area size and airflow path of the ventilation channel.

[0138] Therefore, designing different shapes of the shielding part 112 such as arc-shaped or planar can optimize the airflow path and suction force according to specific cleaning needs, thereby improving cleaning efficiency. The selection of arc-shaped or planar shielding part can be determined based on the cleaning scene and needs, for example, arc-shaped design can be used for scenes that require more precise airflow control, while planar design is suitable for situations that require large-area shielding.

[0139] Optionally, the thickness of the connecting part 111 is greater than the thickness of the shielding part 112.

[0140] Among them, the connecting part 111 is thicker, serving as a fixed end, and the thicker design provides higher structural strength and stability, ensuring that it can be firmly connected with the driving mechanism 16. The shielding part 112 is thinner, serving as a free end, and the thinner design makes it easier to deform and adapt to the ups and downs and unevenness of the cleaning surface.

[0141] In this way, the thicker design of the connecting part 111 increases its fixing ability, ensuring that the shielding part 11 remains stable during the operation of the cleaning device 100 and does not loosen due to vibration or impact. The thinner design of the shielding part 112 improves the deformation ability, allowing the shielding part 11 to more easily adapt to changes in the cleaning surface during cleaning, improving the applicability of the cleaning device 100 and achieving better cleaning effect.

[0142] In addition, the thinner design of the shielding part 112 allows the shielding part 11 to fit the cleaning surface more closely when it is in the first position, reducing air leakage and improving the effectiveness of the suction force, thereby enhancing the cleaning effect. Moreover, the thinner shielding part 112 can also reduce friction and wear on the cleaning surface, protecting the material and appearance of the cleaning surface.

[0143] For example, Figure 8 As shown in the sectional view of the shielding part provided by the utility model, Figure 8 The connecting part 111 includes a soft connecting part 21 and a hard connecting part 22 connected to the soft connecting part 21. The soft connecting part 21 is located near the direction of the roller brush assembly 12, and the hard connecting part 22 is located away from the direction of the roller brush assembly 12.

[0144] Among them, since the soft connecting part 21 is of flexible material characteristics, the soft connecting part 21 can closely fit the surface of the roller brush assembly 12 and its surroundings, providing good sealing performance, while the hard connecting part 22 can provide structural stability and support, ensuring the overall firmness of the connecting part 111.

[0145] Optionally, the soft connecting part 21 is usually made of flexible material, such as rubber or flexible polymer, which has good elasticity and sealing performance, and can adapt to the dynamic movement of the rolling brush assembly 12, and the hard connecting part 22 is usually made of rigid material, such as plastic or metal, which provides necessary structural strength and durability, and ensures the stability of the connecting part 111.

[0146] It should be noted that the material of the soft connecting part 21 and the hard connecting part 22 is not limited in the utility model, and the above is only an example.

[0147] Therefore, the flexible material of the soft connecting part 21 can closely fit the rolling brush assembly 12, reduce air leakage, improve the concentration of suction and cleaning effect, and the soft connecting part 21 can adapt to the dynamic movement of the rolling brush assembly 12, reduce wear and damage caused by vibration or movement, and the hard connecting part 22 provides necessary support and stability, ensures that the cleaning equipment 100 maintains structural integrity during operation, and is not easy to deform, so that by combining flexible and rigid materials, the connecting part 111 can provide good sealing while maintaining durability and long service life, and the combination of soft and hard materials makes the connecting part 111 easier to maintain and clean, reducing the operation burden of the user.

[0148] Optionally, the shielding part 112 can be made of flexible material or hard material, and the material of the shielding part 112 is not limited in the utility model, but the thickness of the shielding part 112 is less than the thickness of the connecting part 111.

[0149] Optionally, as shown in Figure 7 In addition to the structure shown in Figure 2 The cleaning assembly 102 further comprises a driving mechanism 16, which can be used to drive the shielding piece 11 to move between the first position and the second position when the cleaning equipment 100 cleans the carpet, and / or the driving mechanism 16 is used to drive the rolling brush assembly 12 to move between the fifth position and the sixth position, and the driving mechanism 16 is a single motor.

[0150] In the fifth position, the rolling brush assembly 12 is in direct contact with the cleaning surface, and in the sixth position, the rolling brush assembly 12 is away from the cleaning surface, which can reduce unnecessary friction and wear, and the distance of the rolling brush assembly 12 away from the cleaning surface is not limited in the utility model, and the sixth position corresponds to the lifting position of the rolling brush assembly 12, and the sixth position can be set based on actual application scene requirements or product performance.

[0151] Therefore, by driving the positions of the shield 11 and the roller brush assembly 12 through a single driving mechanism 16, the need for manual operation by the user is reduced, enabling the cleaning device 100 to automatically adjust the positions of its components according to different cleaning needs, thereby achieving an ideal cleaning effect on different types of cleaning surfaces. In addition, using the same driving mechanism 16 to control the movement of multiple components reduces the number of independent driving components required in the cleaning device 100, which not only simplifies the mechanical design of the cleaning device 100, but also reduces the complexity of manufacturing and assembly. Moreover, a single driving mechanism can ensure the coordinated consistency of the movements of the shield 11 and the roller brush assembly 12.

[0152] Optionally, when the shield 11 is in the first position, the shield 11 is in contact with the cleaning surface.

[0153] By the shield 11 being in contact with the carpet surface, the shield 11 is in interference fit with the carpet, which can exert additional physical force during cleaning. This contact can help loosen stubborn dirt in the carpet fibers, making it easier to be sucked into the suction cavity 13.

[0154] Therefore, the shield 11 directly contacting the carpet surface can exert additional physical pressure, which helps to loosen and extract deep-seated dirt. This physical action, combined with the enhanced suction force, can significantly improve the cleaning effect on carpets. By optimizing the position of the shield 11, the cleaning device 100 can improve cleaning efficiency without increasing additional energy consumption. This design makes the cleaning device 100 more efficient when dealing with complex surfaces such as carpets.

[0155] It can be understood that the shield 11 in the second position can completely or partially open the ventilation passage 14, increasing the ventilation area. This arrangement is suitable for cleaning hard cleaning surfaces or surfaces that do not require strong suction, providing a wider airflow to cover a larger cleaning area.

[0156] For example, Figure 9 A structure diagram of a shield provided by the present utility model in the first position and the second position is shown in Figure 9 A, where the shield 11 is in the first position, and Figure 9 B, where the shield 11 is in the second position.

[0157] When the cleaning device 100 detects that the cleaning surface to be processed is a carpet or other material that requires deep cleaning, the shield 11 moves to the first position as shown in Figure 9 A, where the ventilation area of the ventilation passage 14 is reduced in the first position, and the suction force is enhanced, which helps to extract dirt deep in the carpet.

[0158] When the cleaning device 100 detects that the cleaning surface is a hard cleaning surface or does not require strong suction, the shield 11 moves toFigure 9 The second position shown in the middle B, in the second position, the ventilation area of the ventilation channel 14 is increased, which helps to quickly clean a large area of the cleaning surface.

[0159] Optionally, the cleaning device 100 further comprises a fan (not shown in the figure), when the shielding piece 11 is in the first position, the rotating speed of the roller brush assembly is 1500-1700 revolutions per minute, and the power of the fan is 30-50W.

[0160] Optionally, the shielding piece 11 also has a seventh position, the ventilation area of the shielding piece 11 at the seventh position is less than or equal to the ventilation area of the shielding piece 11 when the shielding piece 11 is in the first position, when the cleaning surface is a non-carpet, the shielding piece 11 is located at the seventh position, the seventh position can be the same position as the first position, or it can be a different position, when the shielding piece 11 is in the seventh position, the shielding piece 11 is spaced apart from the cleaning surface by a predetermined distance, for example, the predetermined distance is a position 0-2.5mm away from the cleaning surface.

[0161] It should be noted that the present application does not limit the specific value of the predetermined distance, which can be determined based on the application scenario requirements or the material of the cleaning surface.

[0162] It should be noted that the present application does not limit the specific value of the predetermined distance, which can be determined based on the application scenario requirements or the material of the cleaning surface.

[0163] It should be noted that in the present application, non-carpet refers to a flat and hard cleaning area without fluff or thickness, for example, a hard cleaning surface such as wood floor, ceramic tile, stone, vinyl floor, etc., or, non-carpet can specifically refer to a cleaning area that requires less suction and does not require deep cleaning.

[0164] Optionally, when the shielding piece 11 is in the seventh position, the rotating speed of the roller brush assembly is 800-1500 revolutions per minute, and the power of the fan is 30-50W.

[0165] In this way, for non-carpet, maintaining the spacing between the shielding piece 11 and the cleaning surface can reduce unnecessary friction and wear, thereby prolonging the service life of the cleaning assembly 102, and such a setting can also reduce the energy consumption of the cleaning device 100, because the power required for physical contact is reduced, in addition, by providing a variety of seventh position options, the cleaning device 100 can flexibly adapt to different types of non-carpet surfaces, providing more personalized cleaning solutions, such as by adjusting the distance between the shielding piece 11 and the cleaning surface, the cleaning device 100 can achieve an ideal combination of airflow and suction on the non-carpet, thereby improving cleaning efficiency.

[0166] Optionally, when the cleaning device 100 is cleaning a non-carpet surface, the driving mechanism 16 can be used to drive the shield 11 to move between the seventh position and the second position, and / or the driving mechanism 16 can be used to drive the roller brush assembly 12 to move between the fifth position and the sixth position, the roller brush assembly 12 having the fifth position in contact with the cleaning surface and the sixth position away from the cleaning surface, and the driving mechanism 16 is a single motor.

[0167] In this way, by dynamically adjusting the positions of the shield 11 and the roller brush assembly 12 through the single driving mechanism 16, the cleaning device 100 can provide more powerful and effective cleaning on non-carpet surfaces, and such flexibility ensures effective extraction of stubborn dirt or granular dirt, especially under different cleaning requirements, the driving mechanism 16 can quickly adjust the positions of the components, thereby optimizing the energy consumption and cleaning efficiency of the cleaning device 100.

[0168] Therefore, by driving the positions of the shield 11 and the roller brush assembly 12 through the single driving mechanism 16, the need for manual operation by the user is reduced, and in addition, using the same driving mechanism 16 to drive the movements of the shield 11 and the roller brush assembly 12 reduces the number of independent driving components required in the cleaning device 100, simplifies the mechanical design of the cleaning device 100, reduces the complexity of manufacturing and assembly, and also ensures the consistency of the coordinated movements of the shield 11 and the roller brush assembly 12.

[0169] Optionally, the driving mechanism 16 can also be used to drive the squeegee 17 to move between the third position and the fourth position.

[0170] Optionally, the driving mechanism 16 includes a driving part and a transmission mechanism, the transmission mechanism being connected with the shield 11 to drive the shield 11 to move between the first position and the second position, or between the fifth position and the second position.

[0171] Optionally, Figure 10 A cross-sectional view of the cleaning assembly provided by the present application is shown in Figure 10 In addition to the structure shown in Figure 2 The cleaning assembly 102 further includes a limiting part 19 for limiting the position of the shield 11 so that the shield 11 moves between the first position and the second position.

[0172] In some embodiments, the limiting part 19 limits the shield 11 by directly abutting the shield 11, when the shield 11 moves to abut the limiting part 19, the limiting part 19 limits the further movement of the shield 11, thereby limiting the position of the shield 11.

[0173] Therefore, by limiting the moving range of the shielding member 11, the limiting member 19 provides necessary stability to prevent the shielding member 11 from moving or vibrating accidentally during the operation of the cleaning device 100, in addition, the limiting member 19 prevents excessive movement of the shielding member 11, and also avoids potential damage to the internal components of the cleaning device 100 and the cleaning surface.

[0174] It should be noted that the abutment of the shielding member 11 and the limiting member 19 can be the abutment of the main body of the shielding member 11 and the limiting member 19, for example, the limiting member 19 is arranged at the end of the moving path of the shielding member 11, and when the shielding member 11 moves to the first position or the second position, the main body of the shielding member 11 abuts against the limiting member 19; or the abutment of the protruding or recessed part on the shielding member 11 and the limiting member 19, which is not limited in the utility model.

[0175] In another embodiment, the limiting member 19 limits the shielding member 11 by limiting the transmission mechanism or the scraper 17. For example, when the scraper 17 moves to abut against the limiting member 19, the limiting member 19 limits the further movement of the scraper 17, thereby limiting the shielding member 11. Similarly, the abutment of the scraper 17 and the limiting member 19 can be the abutment of the main body of the scraper 17 and the limiting member 19, or the abutment of the protruding or recessed part on the scraper 17 and the limiting member 19.

[0176] In yet another embodiment, the limiting member 19 can be arranged on the housing 103, the limiting member 19 can also be arranged on the first cover plate 104, the limiting member 19 can also be arranged on the second cover plate 105, and the limiting member 19 can also include a plurality of limiting members arranged on one or more of the housing 103, the first cover plate 104 and the second cover plate 105, and the utility model does not limit the arrangement position and the number of the limiting member 19.

[0177] In another embodiment, as shown in Figure 10 The limiting member 19 can include a first limiting part 191 and a second limiting part 192, when the shielding member 11 moves from the second position to the first position, the first limiting part 191 limits the shielding member 11 to avoid further movement of the shielding member 11; when the shielding member 11 moves from the first position to the second position, the second limiting part 192 limits the shielding member 11 to avoid further movement of the shielding member 11. By arranging the first limiting part 191 and the second limiting part 192, the first position and the second position of the shielding member 11 can be limited respectively, so as to ensure the movement of the shielding member 11 between the first position and the second position.

[0178] Please refer to Figure 10In an embodiment, the first limiting part 191 is arranged at the upper edge of the scraper 17 when the scraper 17 moves to the fourth position of being lifted, and the first limiting part 191 can be arranged on the second cover plate 105 or the shell 103. When the scraper 17 moves to the fourth position of being lifted, the scraper 17 abuts against the first limiting part 191, and the first limiting part 191 limits the further movement of the scraper 17. The shielding piece 11 moves reversely synchronously with the scraper 17, and when the scraper 17 abuts against the first limiting part 191, the shielding piece 11 is located at the first position and partially covers the ventilation channel 14.

[0179] The second limiting part 192 is arranged at the upper edge of the shielding piece 11 when the shielding piece 11 moves to the second position, and the second limiting part 192 can be arranged on the first cover plate 104 or the shell 103. When the shielding piece 11 moves from the first position to the second position, the shielding piece 11 abuts against the second limiting part 192, and the further movement of the shielding piece 11 is limited. The first limiting part 191 and the second limiting part 192 are arranged at one side of the scraper 17 and the shielding piece 11 respectively, and control the shielding piece 11 and the scraper 17 to move reversely synchronously, which can further reduce the number of limiting parts arranged and save space. Meanwhile, the first limiting part 191 is arranged at the upper edge of the scraper 17 when the scraper 17 moves to the fourth position, and the second limiting part 192 is arranged at the upper edge of the shielding piece 11 when the shielding piece 11 moves to the second position, which can also avoid interference with the movement path of the scraper 17 and the shielding piece 11 and improve the smoothness of the movement of the scraper 17 and the shielding piece 11.

[0180] The arrangement of the first limiting part 191 and the second limiting part 192 can make the shielding piece 11 and the scraper 17 have a larger contact area with the limiting part 19, thereby reducing the pressure when each component abuts against each other, reducing the probability of damage caused by collision of the shielding piece 11, the scraper 17 and the limiting part 19, and improving the service life.

[0181] Optionally, as shown in Figure 2 and Figure 3 The utility model also provides a cleaning assembly, the cleaning assembly includes: shielding piece 11 and rolling brush assembly 12, shielding piece 11 is movably installed on the equipment main body 101 of cleaning equipment 100, shielding piece 11 includes long arm and the side wall of at least one end along long arm, shielding piece surrounds rolling brush assembly, shielding piece at least has seventh position and second position, and rolling brush assembly 12 includes dust absorption cavity 13, and ventilation channel 14 is formed between dust absorption cavity 13 and cleaning surface, shielding piece 11 covers part ventilation channel 14 when being at seventh position, so that the ventilation area of shielding piece 11 at seventh position is less than the ventilation area of shielding piece 11 when being at second position, and shielding piece 11 is located at seventh position when the cleaning surface is non-carpet.

The effects achieved by the two are similar.

[0183] In this way, when the blocking piece 11 is located at the seventh position, the ventilation passage 14 can be partially covered, and the ventilation area is reduced. This design makes the suction force more concentrated, which can more effectively remove dust and small particles on the non-carpet surface. In addition, for non-carpet surfaces such as hard floors or tiles, concentrated suction force can help to more quickly suck up surface dirt and debris, improve cleaning efficiency, and reduce cleaning time.

[0184] It can be understood that by adjusting the position of the blocking piece 11, the cleaning device 100 can flexibly adapt to different types of cleaning surfaces. The seventh position is suitable for non-carpet surfaces with heavy dust, crumbs, cookie crumbs, cereals, and other small particles.
