Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a roller brush module and cleaning equipment. Background Technology

[0002] Cleaning equipment (such as sweepers and scrubbers) has a roller brush assembly installed at the bottom for cleaning up garbage on the ground. By controlling the rotation of the roller brush assembly, it can clean up hair, paper scraps, dust particles and other garbage on the surface to be cleaned (such as the floor, countertop, wall, carpet). The rotating roller brush can drive the garbage towards the dust collection port of the cleaning equipment so that it can be collected into the dust box that generates negative pressure.

[0003] To facilitate the entry of large particles from the surface to be cleaned into the dustbin, the roller brush assembly is positioned at the bottom of the cleaning device. This creates a suction port between the roller brush assembly and the surface to be cleaned, allowing large particles to pass through and enter the dustbin. However, this structure can lead to lower dust removal efficiency for soft surfaces (such as carpets and blankets). Utility Model Content

[0006] A roller brush body is at least installed at the bottom of the cleaning equipment. Along a first direction, a suction port is formed between the roller brush body and the surface to be cleaned.

[0021] An elastic component is disposed between the roller brush body and the push-pull component. The elastic component can elastically deform between a first form and a second form. When the friction force is removed, the elastic component deforms from one of the first form and the second form to the other form, thereby driving the push-pull component to push the shielding member to a position that increases the suction port.

[0022] Furthermore, the driving component includes:

[0023] A connecting shaft is connected to the brush body and can rotate relative to the brush body about its own axis.

[0033] Wherein, the push-pull component, the elastic component, and the pull rope are all located between the inner wall of the clearance space and the second bracket; and / or,

[0034] Along the second direction, clearance grooves are provided on opposite sides of the first bracket.

[0036] Along the second direction, the driving mechanism is provided at both ends of the second bracket, and a storage cavity is formed between the first bracket and the second bracket. The storage cavity is located on the front side of the cover component. Along the second direction, the clearance openings are provided at both ends of the second bracket. The clearance openings communicate with the storage cavity and extend to the bottom surface of the second bracket along the first direction. When the shielding member moves to the position of increasing the suction port, it is stored in the storage cavity. Along the second direction, the two ends of the shielding member pass through the clearance openings and are connected to the push-pull component.

[0037] Furthermore, the push-pull component includes:

[0038] A crank, along a second direction, is disposed on at least one side of the brush body and can rotate relative to the brush body in a first clockwise direction or a second clockwise direction, wherein the first clockwise direction and the second clockwise direction are opposite;

[0039] The crank includes a first arm and a second arm, which are arranged in a first clockwise direction. The first arm and the second arm form a first angle. The first arm is connected to the drive component, and the second arm is connected to the elastic component and rotatably connected to at least one end of the blocking member in a second direction.

[0040] When the driving component applies the pulling force to the first arm, the crank drives the second arm in a first clockwise direction, so that the second arm drives the blocking member to move to a position where the suction port is reduced. When the pulling force is removed, the elastic component drives the second arm to rotate in a second clockwise direction until the blocking member moves to a position where the suction port is increased.

[0041] Furthermore, the elastic component includes:

[0042] A torsion spring, along the axial direction of the first rotating shaft, is sleeved on the first rotating shaft and located between the roller brush body and the crank.

Along the axial direction of the first rotating shaft, the first torsion arm and the second torsion arm are located on opposite sides of the torsion spring. The first torsion arm abuts against the roller brush body, and the second torsion arm abuts against the second arm. Along the first clockwise direction, the first arm is located between the first torsion arm and the second torsion arm.

[0043] Along the first clockwise direction, the first form is the state of the torsion spring when the first torsion arm and the second torsion arm form a second angle, and the second form is the state of the torsion spring when the first torsion arm and the second torsion arm form a third angle. The second angle is an obtuse angle and is greater than the third angle. During the process of the torsion spring deforming from the second form to the first form, it drives the shielding member to rise, thereby increasing the size of the suction port.

[0044] Furthermore, a second limiting structure is provided between the crank and the torsion spring, the second limiting structure being used to prevent the crank from moving along the second direction to a position detached from the brush body.

[0045] Furthermore, the second limiting structure is disposed between the second torsion arm and the second boom; and / or,

[0046] The second limiting structure includes a limiting groove, the second torsion arm is at least partially bent to form the limiting groove, and the second arm is at least partially adapted to the limiting groove and abuts against the limiting groove.

[0047] On the other hand, this application also provides a cleaning device, comprising:

[0048] Equipment body;

[0049] The roller brush module is located at the bottom of the main body of the device along the first direction.

[0050] In this application, when the roller brush module is installed at the bottom of the cleaning equipment, it can form a suction port between the roller brush module and a hard, flat surface to be cleaned (such as wooden flooring, cement flooring, tile flooring, etc.) to allow large particles of debris to pass through and enter the dust box. When the cleaning equipment enters a rougher, softer surface to be cleaned (such as carpet, rug), to improve the dust removal efficiency of the cleaning equipment, the roller brush module of this application is also equipped with a shielding component. The shielding component is located at least on the front side of the roller brush body, and a drive mechanism is connected to the shielding component. The drive mechanism is configured to drive the shielding component to move up and down relative to the roller brush body under the action of friction applied by the surface to be cleaned, thereby changing the size of the suction port. Specifically, by reducing the size of the suction port, the obstruction reduces the gap between the roller brush module and the surface to be cleaned. During the negative pressure suction operation on the dust box to clean soft surfaces, the airflow from the gap between the roller brush module and the surface towards the dust box is faster and exerts greater force on the soft surface. The airflow can penetrate deeper into the surface (especially soft carpets and blankets), allowing dust particles to be sucked into the dust box more efficiently. Secondly, with a smaller suction port, the space between the roller brush module and the surface is smaller, resulting in better sealing and vacuum. This allows for a stronger suction force at the suction port for dust particles without increasing the suction power, thus improving the dust removal efficiency of the cleaning equipment.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0074] Currently, to facilitate the sweeping of large particles of debris from the surface 400 to be cleaned into the dustbin, the cover structure of the roller brush 200 is angled towards the surface 400, providing a larger front space (i.e., suction inlet 300) for large particles to pass through and enter the dustbin. The airflow for suction enters the dustbin through the suction inlet 300. Because the suction inlet 300 is relatively large, it weakens the airflow velocity across the surface 400 and reduces the airflow volume, resulting in a slower airflow velocity in the area corresponding to the suction inlet 300 and less airflow directly contacting the surface. Furthermore, the larger suction inlet 300 also leads to a lower vacuum between the bottom of the cleaning equipment and the surface 400, resulting in weaker suction for dust particles and making it difficult for them to be drawn into the dustbin, thus reducing dust removal efficiency.

[0075] To address the aforementioned problems, the first embodiment of this utility model provides a roller brush module 00, please refer to [link / reference needed]. Figures 1 to 17 The roller brush module 00 is used to mount the roller brush 200 to the bottom of the cleaning equipment to clean the surface 400 to be cleaned. The roller brush module 00 includes a roller brush body 10 and a shielding assembly 20.

[0076] The roller brush body 10 is at least installed at the bottom of the cleaning equipment to sweep away debris from the surface 400 to be cleaned. Along the first direction (e.g., Figure 3 , Figure 4 (As shown in the Y-direction), a suction port 300 is formed between the roller brush body 10 and the surface 400 to be cleaned. The suction port 300 is used to pierce the debris on the surface 400 into the dust box of the cleaning device. Therefore, the airflow can blow the dust on the surface 400 into the dust box along the suction port 300. Along the forward direction of the cleaning device (e.g., ... Figure 1(In the direction indicated by the middle arrow X), the roller brush body 10 may include a first side 101 (i.e., the front side) and a second side 102 located behind the first side 101. To improve the recovery of large dust particles on the hard, flat surface 400 to be cleaned, in this embodiment, along the first direction, the horizontal plane of the first side 101 is higher than the horizontal plane of the second side 102, so that the roller brush body 10 can form a larger suction port 300 between itself and the surface 400 to be cleaned. The shielding assembly 20 includes a shielding member 21 and a drive mechanism 22.

[0077] Along the forward direction of the cleaning equipment, the shielding member 21 is at least disposed on the front side of the roller brush body 10, that is, the shielding member 21 can be disposed at least on the first side 101, and can also be disposed on the roller brush body 10 along the second direction (e.g. Figure 3 At least one side (in the direction indicated by the middle arrow Z). The drive mechanism 22 is connected to the shield 21. The drive mechanism 22 is configured to drive the shield 21 to move up and down relative to the roller brush body 10 to change the size of the suction port 300 under the action of the frictional force applied by the surface to be cleaned 400.

[0078] When the roller brush module 00 is installed at the bottom of the cleaning equipment, to ensure that a suction port 300 for large particles of debris to pass through and enter the dust box can be formed between the roller brush module 00 and the relatively flat surface to be cleaned 400 (such as a wooden floor, cement floor, tile floor, etc.), the horizontal plane of the first side 101 can be higher than the horizontal plane of the second side 102 along the first direction (indicated by arrow Y in the figure). Therefore, during the cleaning process of the cleaning equipment on the hard, flat surface to be cleaned 400, large particles of debris on the surface to be cleaned 400 can enter the dust box through the suction port 300. In some embodiments, the second side 102 can also be made to be at the same height as the first side 101, thus forming a larger suction port 300 for absorbing large particles of dust.

[0079] When the cleaning device moves onto a relatively rough and soft surface 400 (such as a carpet or blanket), the device will move in a downward position and perform the cleaning work because the surface 400 is soft and has a velvety surface. At this time, the surface 400 will exert friction on the drive mechanism 22. Under the action of friction, the drive mechanism 22 will drive the blocking member 21 to block at least a part of the suction port 300, thereby reducing the size of the suction port 300 and making the gap between the soft surface 400 and the roller brush module 00 smaller. Therefore, during the vacuuming process, not only is the airflow speed faster and the force of the airflow applied to the soft surface 400 stronger, but more airflow is also ensured to flow directly over the soft surface 400, resulting in a higher vacuum between the roller brush module 00 and the surface 400. A higher vacuum leads to greater negative pressure, which in turn increases the suction force on dust particles. After entering the area between the roller brush module 00 and the surface 400 from the suction port 300, the airflow flows along the outer periphery of the roller brush into the dust box of the cleaning equipment. Consequently, dust on the soft surface 400 is more efficiently drawn into the dust box, improving the cleaning efficiency and effectiveness of the cleaning equipment on the soft surface 400.

[0080] The drive mechanism 22 is activated by the friction force and drives the shield 21 to move up and down. This not only eliminates the need for an additional power-consuming drive source, but also ensures that the cleaning equipment can promptly identify the soft surface 400 to be cleaned without the need for additional detection equipment. The drive mechanism 22 then drives the shield 21 to move to the position of reducing the suction port 300, thereby improving dust removal efficiency.

[0081] As can be seen, in this embodiment, the roller brush body 10 of the roller brush module 00 includes a first side 101 and a second side 102. When the roller brush module 00 is installed at the bottom of the cleaning equipment, in order to ensure that the roller brush module 00 can form a suction port 300 between itself and the hard, flat surface to be cleaned 400 (such as a wooden floor, cement floor, tile floor, etc.) for large particles of debris to pass through and enter the dust box, the horizontal plane of the first side 101 must be higher than the horizontal plane of the second side 102 along the first direction. Therefore, the roller brush module 00 is inclined as a whole so that a larger suction port 300 is formed between the first side 101 and the surface to be cleaned 400.

[0082] After the cleaning equipment enters a relatively rough and soft surface 400 to be cleaned (such as a carpet or blanket), in order to improve the dust removal efficiency of the cleaning equipment on the soft surface 400, the roller brush module 00 of this embodiment is also provided with a shielding component 20. The shielding member 21 of the shielding component 20 is disposed on the first side 101, and the drive mechanism 22 is connected to the shielding member 21. The drive mechanism 22 is configured to drive the shielding member 21 to move up and down relative to the roller brush body 10 under the action of the friction force applied by the surface 400 to change the size of the suction port 300. Specifically, when the size of the suction port 300 is reduced, the obstruction member 21 decreases the gap between the roller brush module 00 and the soft surface to be cleaned 400. During the negative pressure operation of the dust box to vacuum the soft surface 400, the airflow flows faster and with greater force from the gap between the roller brush module 00 and the soft surface 400 towards the dust box. This allows the airflow to penetrate deeper into the surface (such as carpets or blankets), resulting in more efficient suction of dust particles from the soft surface 400 into the dust box. Secondly, with a smaller suction port 300, the space between the roller brush module 00 and the surface 400 is smaller, resulting in better sealing and vacuum. Therefore, without increasing the suction force, the suction force generated at the suction port 300 is greater, improving the dust removal efficiency of the cleaning equipment.

[0083] The suction force mentioned in this embodiment is the suction force generated when the air extraction component (such as a vacuum pump) draws negative pressure into the dust box, so that the dust box and the suction port 300 can generate corresponding suction force to realize the recycling of dust particles and other garbage.

[0084] In this embodiment, the shielding member 21 includes a baffle 210, which has a first position where it rises close to the roller brush body 10, and a second position where it descends away from the roller brush body 10 and at least partially protrudes from the bottom surface of the roller brush body 10. When the baffle 210 is in the first position, the size of the suction port 300 is smaller than the size when the baffle 210 is in the second position.

[0085] When the baffle 210 is in the first position, the structure of the roller brush module 00 is as follows: Figure 4 As shown. When the baffle 210 is in the second position, the structure of the roller brush module 00 is as follows. Figure 5As shown. In this embodiment, when the baffle 210 is in the first position, it can at least partially protrude from the bottom surface of the roller brush body 10. However, the volume of the portion of the baffle 210 protruding from the bottom surface of the roller brush body 10 when it is in the first position is smaller than the volume of the portion protruding from the bottom surface of the roller brush body 10 when it is in the second position. This is so that when the baffle 210 is in the first position, the first side 101 of the roller brush module 00 can form a larger suction port 300 between itself and the surface to be cleaned 400. Of course, the baffle 210 in the first position can also be entirely located inside the roller brush body 10, so that the first side 101 of the roller brush module 00 can form an even larger suction port 300 between itself and the surface to be cleaned 400, thereby improving the cleaning efficiency of the cleaning equipment in removing large particles of debris.

[0086] When the baffle 210 is in the second position, it can block at least a portion of the suction port 300, thereby reducing the size of the suction port 300 and making the gap between the soft surface to be cleaned 400 and the roller brush module 00 smaller. Therefore, during vacuuming, the airflow over the soft surface to be cleaned 400 has a faster flow rate, a larger air volume, and a stronger force applied to the flexible cleaning surface. This also creates a higher vacuum level between the surface to be cleaned 400 and the roller brush module 00, resulting in more efficient suction of dust from the soft surface to be cleaned 400 into the dust box. This improves the dust removal efficiency and effectiveness of the cleaning equipment on the soft surface to be cleaned 400.

[0087] Combination Figure 5 and Figure 11 It can be seen that when the baffle 210 in this embodiment is in the first position, it moves along the second direction (e.g., Figure 3 As indicated by arrow Z (in the direction of the length of the roller brush body 10), the projected outer contour of the baffle 210 is located within the projected outer contour of the roller brush body 10. This makes the roller brush module 00 more compact when the baffle 210 is in the first position, and makes the suction port 300 larger, ensuring that large particles can be efficiently collected by the dust box. When the baffle 210 is in the second position, along the second direction, at least part of the projected outer contour of the baffle 210 is located outside the projected outer contour of the roller brush body 10. Thus, during the cleaning process of the cleaning equipment on the soft surface 400 to be cleaned, the baffle 210 will block at least part of the suction port 300, thereby increasing the airflow velocity across the soft surface 400 to be cleaned (such as a carpet), and thus improving the dust collection efficiency and effect. The blocking component 21 of the baffle 210 structure is easy to process and assemble, and has a good blocking effect.

[0088] The baffle 210 may include one or more (such as two or three), and the number is not limited in this embodiment. The baffle 210 may include at least one of the following: metal plate, plastic plate, and wooden plate.

[0089] In this embodiment, the roller brush body 10 may include a cover component 104 and a roller brush 200. The cover component 104 has an opening 103. The roller brush 200 is installed in the opening 103 and can rotate relative to the cover component 104 around its own axis. A drive mechanism 22 is disposed on the cover component 104. The opening 103 connects the suction port 300 and the dust box. Thus, during the rotation of the roller brush 200 to clean the debris, it can sweep up the dust on the surface 400 to be cleaned and even loosen some stubborn dust. After the airflow enters the suction port 300, the airflow blows the loosened dust and the raised dust into the dust box through the gap between the roller brush 200 and the opening 103, making the dust removal efficiency better. The drive mechanism 22 is disposed on the cover component 104 and then installed together with the roller brush body 10 in the receiving cavity 110 at the bottom of the cleaning device, making assembly more convenient and efficient.

[0090] Secondly, in this embodiment, the shielding member 21 can also be directly set on the cover component 104, so that the shielding member 21 and the roller brush body 10 can be installed together on the bottom of the cleaning equipment, which is convenient and efficient to assemble.

[0091] like Figure 9 As shown, the first side 101 is provided with a storage cavity 011, and the baffle 210 (i.e., the shielding member 21) is stored in the storage cavity 011 when it is in the first position. Therefore, in the first position, since the baffle 210 is stored in the storage cavity 011, the roller brush module 00 is more compact, while the baffle 210 is also protected from damage or corrosion caused by long-term exposure. The length of the roller brush module 00 is along the second direction, and the length of the baffle 210 extends along the second direction; that is, the baffle 210 is a plate-like structure extending along the second direction. Thus, only one baffle 210 needs to be installed to shield the suction port 300 formed between the various parts of the roller brush module 00 along its length and the surface to be cleaned 400, making assembly efficient and convenient.

[0092] A first limiting structure 30 is provided between the baffle 210 (i.e., the blocking member 21) and the roller brush body 10. The first limiting structure 30 is used to limit the movement trajectory of the baffle 210 during its lifting and lowering motion. Thus, during the lifting and lowering motion of the baffle 210, the first limiting structure 30 can ensure that the baffle 210 will not shake or sway, thereby improving the stability and accuracy of the baffle 210 when it lifts and lowers between the first position and the second position.

[0093] When the cover component 104 of the roller brush body 10 includes a first support 11 and a second support 12 connected to each other, the receiving cavity 011 is formed between the first support 11 and the second support 12. Along the forward direction of the cleaning device, the first limiting structure 30 is disposed between the second support 12 (i.e. the bottom of the receiving cavity 011) and the baffle 210.

[0094] like Figures 10 to 11 As shown, the first limiting structure 30 includes a limiting hole 31 and a limiting block 32. The limiting hole 31 is disposed on the second bracket 12 and extends to the bottom surface of the second bracket 12 along the first direction, and at least one limiting hole 31 is respectively disposed on each of the opposite sides of the second bracket 12 along the second direction. The limiting block 32 is disposed at the opposite ends of the baffle 210 along the second direction and is disposed corresponding to the limiting hole 31. The limiting block 32 is adapted to the limiting hole 31 and inserted into the limiting hole 31. During the lifting and lowering movement of the baffle 210, the limiting block 32 is always located within the limiting hole 31 and can move with the baffle 210 relative to the limiting hole 31, thereby ensuring that the baffle 210 is not prone to shaking or swaying during the lifting and lowering movement, and improving the stability and reliability of the baffle 210 during the movement. The limiting block 32 can be integrally formed with the baffle 210. When the limiting block 32 moves to the second position with the baffle 210, it can also block the suction port 300 on both sides along the second direction, so that the airflow flowing through the surface to be cleaned 400 is more concentrated, the airflow is larger, the wind speed is faster, and the wind force is stronger, so as to improve the dust removal efficiency.

[0095] like Figure 11 As shown, a guide structure 60 is also provided between the shielding member 21 (such as baffle 210) and the inner wall surface of the receiving cavity 011. The guide structure 60 includes a guide protrusion 61 and a guide groove 62. The guide protrusion 61 is provided at opposite ends of the shielding member 21 along the second direction, and the guide groove 62 is provided on the inner wall surface of opposite sides of the receiving cavity 011 along the second direction. The guide groove 62 extends along the movement direction of the shielding member 21. The guide protrusion 61 is adapted to the guide groove 62 and can move with the shielding member 21 relative to the guide groove 62. This guide structure 60 can further ensure the stability of the shielding member 21 during the lifting and lowering process and prevent the shielding member 21 from swaying relative to the brush body 10.

[0096] In this embodiment, the roller brush module 00 also includes a scraper 13. Along the forward direction of the cleaning device, the scraper 13 is disposed on the rear side of the roller brush body 10 away from the shield 21, that is, on the second side 102 of the roller brush body. In this case, the scraper 13 can be connected to the roller brush body 10 or to the device body 100 of the cleaning device (such as the bottom shell of the device 100). Figure 6 and Figure 7As shown, the scraper 13 is configured to closely adhere to the surface 400 to be cleaned and surround the baffle 210 located at the second position to form a suction chamber 500, which is connected to the suction port 300. Because the scraper 13, closely adhering to the surface 400 to be cleaned, seals the side of the roller brush module 00 away from the suction port 300 between the roller brush module 00 and the surface to be cleaned, the suction chamber 500 achieves better sealing. During the suction process, the vacuum level generated within the suction chamber 500 will be higher, the negative pressure will be greater, and the airflow velocity and flow rate along the suction port 300 across the surface to be cleaned will be higher, thereby further improving the dust removal effect. At this time, the airflow path is as follows: suction port 300 → dust suction chamber 500 → installation gap between the outer peripheral surface of roller brush 200 and roller brush module 00, gap between the bristles of roller brush 200 → dust box. Under this path, along the forward direction of the cleaning equipment, dust is less likely to run from the second side 102 away from the suction port 300 to other positions of the cleaning equipment due to the inertia of motion, and the dust collection efficiency is also higher.

[0097] Along the forward direction of the cleaning equipment, the scraper 13 and the baffle 210 are respectively connected to the opposite sides of the cover component 104. Thus, in this embodiment, after the scraper 13 and the baffle 210 are assembled onto the cover component 104, they can be assembled together with the cover component 104 at the bottom of the cleaning equipment, making assembly convenient and efficient.

[0098] like Figure 7 As shown, the surface of the surface to be cleaned 400 has a pile (such as the pile on a carpet). When the baffle 210 is in the second position, the side of the baffle 210 closest to the surface to be cleaned 400 is in contact with the pile. At this time, the baffle 210 can just touch the pile or squeeze the pile. As a result, during the process of airflow flowing into the dust box from the suction port 300 between the baffle 210 and the surface to be cleaned 400, more airflow can directly and fully contact the pile and the main body of the surface to be cleaned 400 at the bottom of the pile, effectively and promptly blowing the dust particles hidden between the pile and on the main body of the surface to be cleaned 400 into the dust box, resulting in better dust removal efficiency and effect.

[0099] like Figure 5 , Figures 10 to 11 as well as Figure 15 As shown, the drive mechanism 22 in this embodiment includes a drive component 221, a push-pull component 222, and an elastic component 223. The push-pull component 222 is disposed on the brush body 10 and connected between the shield 21 and the drive component 221. The drive component 221 is configured to apply a pulling force to the push-pull component 222 under the action of friction, so that the push-pull component 222 pulls the shield 21 to the position of reducing the suction port 300, that is, the baffle 210 moves from the first position to the second position.

[0100] The elastic component 223 is located between the roller brush body 10 and the push-pull component 222. The elastic component 223 can elastically deform between the first and second forms. When the friction is removed, the elastic component 223 deforms from one of the first and second forms to the other, driving the push-pull component 222 to push the baffle 21 to a position where the suction port 300 is enlarged. That is, the baffle 210 returns from the second position to the first position, and the size of the suction port 300 is reduced in the first position. Furthermore, the drive component 221 applies a pulling force to the push-pull component 222 by relying on friction, eliminating the need for an additional power-consuming drive source, reducing the energy consumption of the cleaning equipment, making it more energy-efficient and cost-effective, and providing a better user experience.

[0101] Therefore, when the cleaning equipment cleans soft surfaces such as carpets 400, the pulling force applied by the drive component 221 to the push-pull component 222 enables the push-pull component 222 to overcome the elastic force of the elastic component 223 and pull the blocking component 21 to the position of reduced suction port 300, thereby improving the dust removal efficiency of the cleaning equipment on the soft surfaces 400. When the cleaning equipment cleans flat surfaces 400, the elastic deformation of the elastic component 223 drives the push-pull component 222 to push the blocking component 21 back to the position of increased suction port 300. Since the reset of the blocking component 21 is provided by the elastic deformation force of the elastic component 223, the reset process is not only fast and reliable, but also can be achieved without the need for an additional power source.

[0102] In this embodiment, the elastic component 223 may include a spring. The first configuration can be either a compressed state or a stretched state of the spring, and the second configuration can be the other of both compressed and stretched states. The specific form of the first and second configurations can be determined according to the specific installation position of the spring; this embodiment does not impose a single limitation.

[0103] like Figure 10 and Figure 11 As shown, the driving component 221 in this embodiment includes a connecting shaft 211, a rolling element 212, and a pull rope 213. The connecting shaft 211 is connected to the brush body 10 and can rotate relative to the brush body 10 about its own axis. The rolling element 212 is sleeved on the connecting shaft 211 and can drive the connecting shaft 211 to rotate relative to the brush body 10 when subjected to friction.

[0104] One end of the pull rope 213 is connected to the connecting shaft 211, and the other end is connected to the push-pull component 222. During the rotation of the connecting shaft 211, the pull rope 213 is at least partially wrapped around the connecting shaft 211 to apply a pulling force to the push-pull component 222. When the friction is removed, the pulling force on the push-pull component 222 is also removed, and the elastic component 223 drives the push-pull component 222 to push the blocking component 21 back to the position of increasing the suction port 300, or in other words, pushes the baffle 210 from the second position back to the first position.

[0105] As the cleaning device moves the rolling element 212 forward on the soft surface 400 (such as a carpet), the entire cleaning device sinks. The frictional force experienced by the rolling element 212 is specifically the frictional force generated between the soft surface 400 and the rolling element 212 when the rolling element 212 comes into contact with the pile of the soft surface 400 (such as a carpet). At this time, the rolling element 212 can drive the connecting shaft 211 to rotate under the action of friction. During the rotation of the connecting shaft 211, the pull rope 213 continuously winds around the connecting shaft 211, thereby enabling the pull rope 213 to apply a pulling force to the push-pull component 222, so that the push-pull component 222 can pull the shielding component 21 to the position of reducing the suction port 300 under the action of the pulling force.

[0106] Therefore, the drive component 221 in this embodiment does not need to be equipped with a power source (such as a motor) or a detection component (such as a sensor or image detector for detecting whether the surface to be cleaned 400 is flat or soft). The push-pull component 222 can be driven to pull the shield 21 by the friction generated between the rolling component 212 and the soft surface to be cleaned 400. The drive method is timely, reliable and low cost.

[0107] After the cleaning device drives the rolling element 212 back to the flat surface to be cleaned 400, the friction force on the rolling element 212 will be removed, meaning there will be a gap between the rolling element 212 and the flat surface to be cleaned 400 without it contacting the surface. Then, the elastic component 223 will drive the push-pull component 222 to push the blocking component 21 back from the second position to the first position. During this process, the portion of the pull rope 213 wrapped around the connecting shaft 211 will separate from the connecting shaft 211 and be released.

[0108] In one embodiment, when the roller brush body 10 includes a cover component 104 and a roller brush 200, the cover component 104 defines an opening 103 communicating with the suction port 300. Along the second direction, a drive mechanism 22 is disposed at at least one end of the cover component 104. When drive mechanisms 22 are provided at both ends of the cover component 104, the push-pull component 222 is more effortless and stable. Along the forward direction of the cleaning device, a shielding member 21 is disposed on the front side of the cover component 104. Along the forward direction of the cleaning device (i.e., the width direction of the cover component 104), a connecting shaft 211 is rotatably connected to the side of the cover component 104 away from the shielding member 21. This not only facilitates assembly but also makes full use of the installation space in the width direction of the cover component 104, resulting in high space utilization. The roller brush 200 is installed within the opening 103 and can rotate relative to the cover component 104 about its own axis.

[0109] The roller brush module 00 also includes a scraper 13. Along the forward direction of the cleaning device, the scraper 13 is connected to the rear side of the cover component 104 and located between the connecting shaft 211 and the shielding member 21. Thus, this embodiment makes full use of the space in each area of ​​the cover component 104 in the width direction to assemble the scraper 13, the connecting shaft 211, the rolling member 212 sleeved on the connecting shaft 211, and the shielding member 21. The overall structure is more compact and reliable, and the space utilization rate is high. Moreover, the scraper 13 is configured to be in close contact with the surface to be cleaned so that the scraper 13 and the shielding member 21 can form a dust suction chamber 500, further improving the dust removal efficiency.

[0110] Along the first direction, the bottom surface of the scraper 13 away from the cover component 104 is located below the roller 212 and has an installation gap with the roller 212. Therefore, whether on a flat surface 400 or a soft surface 400 to be cleaned, the scraper 13 can always contact the surface 400 to be cleaned and scrape up the dirt and dust on the surface 400. At the same time, since the bottom surface of the scraper 13 away from the first bracket 11 is located below the roller 212 and has an installation gap with the roller 212, when the cleaning device is located on a flat surface 400 to be cleaned, the roller 212 will not contact the flat surface 400 to be cleaned, thereby preventing the roller 212 from rolling and keeping the shield 21 in the first position. When the cleaning device is positioned on the soft surface to be cleaned 400, the lint on the soft cleaning surface will extend to the rolling element 212 on the upper part of the scraper 13 and come into contact with the rolling element 212 to generate friction. This allows the rolling element 212 to roll under the action of friction, thereby enabling the push-pull component 222 to pull the blocking component 21 to the second position to block or seal the suction port 300, thereby improving the dust removal efficiency of the soft surface to be cleaned 400.

[0111] As can be seen, in this embodiment, the scraper 13 is connected to the cover component 104. Along the forward direction of the cleaning device, the scraper 13 and the shield 21 are located on opposite sides of the cover component 104. Along the forward direction of the cleaning device, the connecting shaft 211 is located on the side of the scraper 13 away from the shield 21. The cover component 104 has high space utilization and a compact and stable overall structure. The scraper 13 is configured to be in close contact with the surface to be cleaned, so that the scraper 13 and the shield 21 located in the descending position (i.e., the position of the reduced suction port 300) can form a dust suction chamber 500, thereby further improving the dust removal efficiency and effect.

[0112] Specifically, such as Figures 3 to 14As shown, the cover component 104 of the roller brush body 10 in this embodiment includes a first bracket 11 and a second bracket 12. The second bracket 12 is connected to the first bracket 11, and the second bracket 12 and the first bracket 11 define an opening 103. The second bracket 12 is also configured to rotate relative to the first bracket 11 in a first direction. After the roller brush 200 is mounted on the roller brush body 10, it is exposed in the opening 103 so that the roller brush 200 can clean the surface 400 to be cleaned. In a second direction, a drive mechanism 22 is provided at at least one end of the second bracket 12, and a connecting shaft 211 is rotatably connected to the second bracket 12 so that the pull rope 213 can be wound around the connecting shaft 211 during the rotation of the rolling element 212. In the forward direction of the cleaning device, the connecting shaft 211 is located on the side away from the blocking element 21 of the push-pull member 222 and the elastic member 223.

[0113] The scraper 13 is connected to the second bracket 12 and located on the second side 102. Along the forward direction of the cleaning device, the connecting shaft 211 is located on the side of the scraper 13 away from the shield 21, and the scraper 13 is configured to be in close contact with the surface 400 to be cleaned.

[0114] Furthermore, the scraper 13 can push the second bracket 12 to rotate relative to the first bracket 11 under the action of external force, so that the scraper 13 can always be in close contact with the surface 400 to be cleaned with undulating areas, scraping up and loosening the dust and debris on the surface 400 to be cleaned, thereby improving the cleaning effect of the cleaning equipment on the surface 400 to be cleaned.

[0115] In this embodiment, a shielding member 21 is provided on the first side 101 of the roller brush body 10, and a scraper 13 is provided on the second side 102. Since the horizontal plane of the second side 102 where the scraper 13 is located is lower, it is easier for the scraper 13 to fit tightly against the surface to be cleaned 400, reducing the assembly difficulty and material usage of the scraper 13. At the same time, the scraper 13, which is in close contact with the surface to be cleaned 400, can form a suction chamber 500 with the shielding member 21 located in the lowered position (i.e., the position of the reduced suction port 300), and the suction chamber 500 is connected to the suction port 300. That is, the scraper 13 can seal the side of the roller brush module 00 away from the suction port 300 between the roller brush module 00 and the surface to be cleaned, resulting in better sealing of the suction chamber 500. During the dust collection process, the vacuum degree generated in the suction chamber 500 will be higher, the negative pressure generated will be greater, and the airflow velocity and flow rate along the suction port 300 through the surface to be cleaned will be greater, thereby further improving the dust removal effect. At this time, the airflow path is as follows: suction port 300 → dust suction chamber 500 → installation gap between the outer peripheral surface of roller brush 200 and roller brush module 00 → dust box. Under this path, along the forward direction of the cleaning equipment, dust is less likely to run from the second side 102 away from the suction port 300 to other positions of the cleaning equipment due to the inertia of motion, and the dust collection efficiency is also higher.

[0116] like Figure 5As shown, along the first direction, the bottom surface of the scraper 13 away from the first support 11 is located below the roller 212 and has an installation gap with the roller 212. Therefore, whether on a flat surface 400 or a soft surface 400 to be cleaned, the scraper 13 can always contact the surface 400 to be cleaned and scrape up the dirt and dust on the surface 400. At the same time, because the bottom surface of the scraper 13 away from the first support 11 is located below the roller 212 and has an installation gap with the roller 212, when the cleaning device is located on a flat surface 400 to be cleaned, the roller 212 will not contact the flat surface 400 to be cleaned, thereby preventing the roller 212 from rolling and keeping the shield 21 in the first position. When the cleaning device is positioned on the soft surface to be cleaned 400, the lint on the soft cleaning surface will extend to the rolling element 212 on the upper part of the scraper 13 and come into contact with the rolling element 212 to generate friction. This allows the rolling element 212 to roll under the action of friction, thereby enabling the push-pull component 222 to pull the blocking component 21 to the second position to block or seal the suction port 300, thereby improving the dust removal efficiency of the soft surface to be cleaned 400.

[0117] like Figures 8 to 9 As shown, the roller brush body 10 also includes a flexible connector 14, which connects the scraper blade 13 and the first support 11. The flexible connector 14 is used to limit the distance by which the scraper blade 13 rises or falls relative to the first support 11 in a first direction. The flexible connector 14 can specifically be at least one of a flexible rubber sheet, a flexible silicone sheet, etc. Figure 9 and Figure 11 As shown, the roller brush body 10 also includes a snap-fit ​​block 15, which is located on the second side 102 and fixes the scraper 13 to the second bracket 12.

[0118] A second rotatable connection structure 70 is provided between the connecting shaft 211 and the second bracket 12, such as... Figure 15 As shown, the second rotating connection structure 70 includes a bearing 71 and a second connecting hole 72. The second connecting hole 72 is disposed on the second bracket 12, the bearing 71 is installed in the second connecting hole 72, and one end of the connecting shaft 211 near the second bracket 12 is fixedly connected to the inner ring of the bearing 71. Thus, when the rolling element 212 is subjected to frictional force, the connecting shaft 211 can be driven to rotate stably and reliably, which is convenient for assembly and ensures stable and reliable rotational movement of the connecting shaft 211.

[0119] In this embodiment, the rolling element 212 may specifically include a roller, and the surface of the roller along its own radial direction may be provided with multiple protrusions 120, such as... Figure 11 As shown, multiple protrusions 120 are spaced apart circumferentially along the roller. This allows for greater friction between the roller and the soft surface 400 to be cleaned, thereby ensuring that the roller can reliably apply pulling force to the push-pull member 222.

[0120] In this embodiment, a snap-fit ​​structure 80 is provided between the pull rope 213 and the connecting shaft 211 to ensure that the pull rope 213 can wind around the connecting shaft 211 when the connecting shaft 211 rotates. For example... Figure 17 As shown, the snap-fit ​​structure 80 includes an annular boss 81 and a ball head 82. The annular boss 81 is disposed on the outer peripheral surface of the connecting shaft 211 and located between the rolling element 212 and the bearing 71. Along the axial direction of the connecting shaft 211, the annular boss 81 has a snap-fit ​​groove 811 on the side away from the bearing 71, and an annular groove 812 is also provided along the circumferential direction of the connecting shaft 211. The snap-fit ​​groove 811 extends to and communicates with the annular groove 812 on the side near the bearing 71. The ball head 82 is disposed at one end of the pull rope 213 near the connecting shaft 211 and snaps into the snap-fit ​​groove 811. At least a portion of the pull rope 213 near the ball head 82 is located in the snap-fit ​​groove 811 and is disposed opposite to the annular groove 812. Therefore, during the rotation of the connecting shaft 211, the pull rope 213 can be wound around the connecting shaft 211 along the annular groove 812. The annular groove 812 can also ensure that the part of the pull rope 213 wound around the connecting shaft 211 is not prone to deviation, and the winding is more stable and tight.

[0121] Along the first direction, a first support 11 has a through hole 111, and a second support 12 has a through hole 121. The second through hole 121 communicates with the first through hole 111 and forms an opening 103 by surrounding the inner wall of the first through hole 111. Figure 14 As shown, along the first direction, at least one side of the first support 11 is provided with a clearance space 112, and the opposite sides of the second support 12 along the second direction are both located within the clearance space 112.

[0122] The push-pull component 222, the elastic component 223, and the pull rope 213 are all located between the inner wall of the clearance space 112 and the second support 12. Therefore, by placing the push-pull component 222, the elastic component 223, and the pull rope 213 between the clearance space 112 and the second support 12, this embodiment improves the compactness of the roller brush module 00 and enhances the protective performance of the push-pull component 222, the elastic component 223, and the pull rope 213, preventing them from being interfered with or damaged by objects in the external environment, thus improving the reliability and service life of the drive mechanism 22.

[0123] Specifically, the second bracket 12 can be rotatably connected to the first bracket 11 on the side away from the scraper 13 along the forward direction of the cleaning equipment. For this purpose, a fourth rotatable connection structure 16 can be provided between the second bracket 12 and the first bracket 11. Figure 10 and Figure 14It is understood that the fourth rotating connection structure 16 may include a rotating hole 161 and a protruding post 162. The protruding post 162 protrudes from opposite ends of the second bracket 12 along the second direction. Along the second direction, the rotating hole 161 is disposed on the inner side of opposite sides of the clearance space 112 of the first bracket 11 and is correspondingly disposed with respect to the protruding post 162. The protruding post 162 is inserted into the rotating hole 161 and can rotate relative to the rotating hole 161.

[0124] like Figure 14 As shown, along the second direction, the first bracket 11 is provided with relief grooves 113 on both sides. The relief grooves 113 are arranged opposite to the connecting shaft 211 and communicate with the relief space 112. The rolling element 212 passes through the relief groove 113 at least partially and is sleeved on the connecting shaft 211. Thus, the rolling element 212 can better contact the soft surface 400 to be cleaned, and the assembly is convenient and efficient.

[0125] When the shield 21 is in the first position and the second position, the pull rope 213 can be in a taut state, thereby preventing at least part of the pull rope 213 from falling outside the roller brush module 00 due to excessive length.

[0126] like Figure 11 and Figure 15 As shown, at least one end of the second bracket 12 is provided with a mounting groove 122 along the second direction, and the mounting groove 122 extends along the forward direction of the cleaning equipment. The connecting shaft 211 is rotatably connected to the bottom of the mounting groove 122 along the second direction, that is, the second rotating connection structure 70 is provided at the bottom of the mounting groove 122. The push-pull component 222 and the elastic component 223 are both provided in the mounting groove 122, and the portion of the pull rope 213 located between the connecting shaft 211 and the push-pull component 222 is laid on the bottom of the mounting groove 122 along the first direction. The mounting groove 122 increases the space between the second bracket 12 and the inner wall of the clearance space 112, thereby reserving sufficient installation space for the assembly of each component of the drive mechanism 22, resulting in high space utilization.

[0127] The portion of the pull rope 213 located between the connecting shaft 211 and the push-pull component 222 is laid at the bottom of the mounting groove 122 along the first direction to ensure the assembly stability of the pull rope 213 and prevent the pull rope 213 from being exposed.

[0128] Along the second direction, driving mechanisms 22 are provided at both ends of the second bracket 12, and a storage cavity 011 is formed between the first bracket 11 and the second bracket 12. The storage cavity 011 is located on the first side 101. Along the second direction, clearance openings 123 are provided at both ends of the second bracket 12. The clearance openings 123 communicate with the storage cavity 011 and extend to the bottom surface of the second bracket 12 along the first direction. When the shielding member 21 is in the descending position of the enlarged suction port 300, it is stored in the storage cavity 011. Along the second direction, the two ends of the shielding member 21 pass through the clearance openings 123 and are connected to the push-pull member 222.

[0129] Therefore, by connecting at least two sets of drive mechanisms 22 at opposite ends of the second bracket 12 to opposite ends of the blocking member 21, the blocking member 21 can be driven to move up and down by at least two sets of drive mechanisms 22. This makes the drive more reliable and precise, and also improves the stability of the blocking member 21 at the upper limit position (i.e., the first position of the baffle 210) and the lower limit position (i.e., the second position of the baffle 210). The clearance opening 123 is located on the extension path of the guide groove 62 and communicates with the guide groove 62, so that the structure of the second bracket 12 is more compact and the space utilization rate is high.

[0130] like Figure 11 As shown, the push-pull component 222 in this embodiment includes a crank 220. Along the second direction, the crank 220 is located on at least one side of the brush body 10 and can rotate relative to the brush body 10 in a first clockwise direction or a second clockwise direction. The first clockwise direction and the second clockwise direction are opposite, such as when the first clockwise direction is clockwise (e.g., when the first clockwise direction is clockwise). Figure 11 The direction indicated by arrow S is shown), and the second clockwise direction is the counterclockwise direction (as shown by arrow S). Figure 11 (The direction indicated by arrow N shown). When a drive mechanism 22 is provided at both ends of the second bracket 12, a crank 220 is provided at both ends of the second bracket 12.

[0131] The crank 220 includes a first arm 201 and a second arm 202. The first arm 201 and the second arm 202 form a first angle along a first clockwise direction. The first arm 201 is connected to the drive component 221, and the second arm 202 is connected to the elastic component 223 and is rotatably connected to at least one end of the blocking member 21 along a second direction.

[0132] When the drive component 221 applies a pulling force to the first arm 201, the crank 220 drives the second arm 202 in the first clockwise direction, so that the second arm 202 drives the blocking component 21 to the lower position of the reduced suction port 300. When the pulling force is removed, the elastic component 223 drives the second arm 202 to rotate in the second clockwise direction until the blocking component 21 moves to the upper position of the increased suction port 300.

[0133] Therefore, during the rotational motion of the crank 220 under the action of tension in this embodiment, the second arm 202 can drive the blocking member 21 to move up and down. The push-pull component 222 of the crank 220 structure is easy to process, easy to assemble, and low in cost, and the push-pull of the blocking member 21 is reliable and stable.

[0134] The storage cavity 011 formed by the first bracket 11 and the second bracket 12 is inclined. Specifically, the storage cavity 011 is inclined towards the second side 102. Therefore, the shielding member 21 installed in the storage cavity 011 is also inclined, and the bottom of the shielding member 21 along the first direction is closer to the second side 102 than the top. The clearance opening 123 on the second bracket 12 that communicates with the storage cavity 011 is also inclined. At this time, the clearance opening 123 does not need to be made large to meet the space required for the crank 220 to pull the shielding member 21 to perform lifting and lowering movements. This not only ensures the structural strength of the second bracket 12, but also makes the roller brush body 10 more compact, thereby saving installation space for the cleaning equipment.

[0135] A first rotatable connection structure 40 is provided between the crank 220 and the brush body 10. The first rotatable connection structure 40 includes a first rotating shaft 41 and a first connecting hole 42. The first rotating shaft 41 is disposed on the brush body 10, and the axis of the first rotating shaft 41 is parallel to a second direction. The first connecting hole 42 is disposed on the crank 220, and the crank 220 is sleeved on the first rotating shaft 41 through the first connecting hole 42 and can rotate around the axis of the first rotating shaft 41. In this embodiment, a limiting member (such as a protrusion) can be provided on the first rotating shaft 41, and the limiting member is located on the side of the crank 220 away from the brush body 10 along the axial direction of the first rotating shaft 41. This limits the crank 220 and prevents the crank 220 from detaching from the brush body 10.

[0136] like Figure 16 As shown, a second limiting structure 50 is provided between the crank 220 and the elastic component 223. The second limiting structure 50 is used to prevent the crank 220 from moving along the second direction to the position of being separated from the brush body 10 or from the position of being separated from the first rotating shaft 41.

[0137] Therefore, in this embodiment, the crank 220 is sleeved on the first rotating shaft 41 through the first connecting hole 42, and the crank 220 is restricted by the second limiting structure 50, thus stably mounting the crank 220 onto the roller brush body 10. During the rotation of the crank 220, it will not fall off the first rotating shaft 41, resulting in a stable and reliable overall assembly structure, and making assembly more efficient and convenient. The first rotating shaft 41 can be connected to the second bracket 12, or it can be integrally formed with the second bracket 12. When integrally formed, the assembly steps of the crank 220 and the roller brush body 10 can be reduced, making assembly more efficient.

[0138] Along the radial direction of the first pivot 41, the length of the first arm 201 is less than the length of the second arm 202, so that the first arm 201 can occupy less installation space while making it easier to pull the first arm 201 with the pull rope 213. The second arm 202 is longer, which allows the second arm 202 to accurately drive the blocking member 21 to move between the first position and the second position.

[0139] To ensure a rotatable connection between the second boom 202 and the blocking member 21, a third rotatable connection structure 90 can be provided between the second boom 202 and the blocking member 21. For example... Figure 11 As shown, the third rotating connection structure 90 includes a third connecting hole 91 and a second rotating shaft 92. The second rotating shaft 92 is disposed at the end of the shielding member 21 along the second direction, and the third connecting hole 91 is disposed on the second arm 202. When the shielding member 21 is located in the receiving cavity 011, the second rotating shaft 92 passes through the clearance opening 123 and is rotatably connected to the third connecting hole 91.

[0140] The second pivot 92 can be integrally formed with the shield 21 to improve the stability of the second pivot 92 and facilitate the assembly between the shield 21 and the crank 220. Meanwhile, since the second limiting structure 50 between the elastic member 223 and the second arm 202 prevents the crank 220 and its second arm 202 from moving in the second direction, no additional limiting measures are needed between the second pivot 92 and the third connecting hole 91 to ensure that the shield 21 can be stably rotatably connected to the second arm 202.

[0141] like Figure 11 As shown, the elastic component 223 in this embodiment may specifically include a torsion spring 231. Along the axial direction of the first rotating shaft 41, the torsion spring 231 is sleeved on the first rotating shaft 41 and located between the roller brush body 10 and the crank 220. The torsion spring 231 includes a first torsion arm 311 and a second torsion arm 312. Along the axial direction of the first rotating shaft 41, the first torsion arm 311 and the second torsion arm 312 are located on opposite sides of the torsion spring 231. The first torsion arm 311 abuts against the roller brush body 10, and the second torsion arm 312 abuts against the second arm 202. When the crank 220 is installed in the mounting groove 122 of the second bracket 12, the first torsion arm 311 specifically abuts against the inner wall surface of the mounting groove 122. Furthermore, when the blocking member 21 is in the first position, the inner wall surface of the mounting groove 122 near the clearance opening 123 can also restrict the second arm 202, thereby improving the stability of the blocking member 21 in the first position.

[0142] Along the first clockwise direction, the first arm 201 is located between the first torsion arm 311 and the second torsion arm 312. Along the first clockwise direction, the first configuration is the state of the torsion spring 231 when the first torsion arm 311 and the second torsion arm 312 form a second angle, and the second configuration is the state of the torsion spring 231 when the first torsion arm 311 and the second torsion arm 312 form a third angle. The second angle is an obtuse angle and is greater than the third angle. During the process of the torsion spring 231 deforming from the second configuration to the first configuration, it drives the blocking member 21 to rise, that is, it drives the baffle 210 to return from the second position to the first position, so as to increase the size of the suction port 300.

[0143] After the first arm 201 is connected to the pull rope 213, the pull rope 213 pulls the first arm 201 to rotate the crank 220 in a first clockwise direction. As the first arm 201 rotates towards the first torsion arm 311, the second arm 202 pulls the shield 21 to the position of reducing the suction port 300. At this time, the first torsion arm 311 and the second torsion arm 312 form a third angle. After the pull rope 213 releases its tension on the first arm 201, the angle between the second torsion arm 312 and the first torsion arm 311 increases to a second angle. As the second torsion arm 312 pushes the second arm 202 to rotate the crank 220 in a second clockwise direction, it pushes the shield 21 to the position of increasing the suction port 300.

[0144] As can be seen, in this embodiment, the torsion spring 231 structure is used to reset the crank 220 to the blocking member 21. The torsion spring 231 structure has high strength, and the force applied by the torsion spring 231 to the crank 220 during reset is large. The reset operation is stable and reliable, and it will make the service life of the drive mechanism 22 longer.

[0145] The second limiting structure 50 is disposed between the second torsion arm 312 and the second arm 202, which not only enables the second torsion arm 312 and the second arm 202 to abut against each other, but also limits the crank 220, making assembly efficient and convenient.

[0146] like Figure 16 As shown, the second limiting structure 50 includes a limiting groove 51. The second torsion arm 312 is at least partially bent to form the limiting groove 51, and the second arm 202 is at least partially adapted to and abuts against the limiting groove 51. The limiting groove 51 can be formed by directly bending the tail end of the second torsion arm 312, making processing convenient and efficient. In other words, this embodiment only requires bending a limiting groove 51 structure adapted to the second arm 202 onto the second torsion arm 312, achieving mutual abutment between the second torsion arm 312 and the second arm 202 while ensuring that the crank 220 is stably mounted on the first rotating shaft 41, preventing the crank 220 from detaching from the brush body 10 during rotation. The second limiting structure 50 is simple and convenient to set, requiring no additional limiting design components, resulting in low assembly difficulty and low cost.

[0147] As can be seen from the above, this embodiment, based on the characteristic that the cleaning device sinks when it enters a soft surface 400 (such as a carpet), designs a roller brush module 00 in which the shield 21 automatically descends when entering the soft surface 400 and automatically rises when exiting the soft surface 400. The shield 21 of the roller brush module 00 can automatically switch between a first position and a second position, so that when on the soft surface 400, the shield 21 can block or seal the suction port 300 formed between the roller brush body 10 and the surface 400, improving dust removal efficiency. On floors / tiles or other hard surfaces, it can also efficiently collect large particles of debris.

[0148] The rolling element 212 of the drive mechanism 22 does not contact the surface 400 to be cleaned on a hard, flat surface, but has an interference fit with the fibers of the soft surface 400 to be cleaned. This allows the cleaning device to automatically identify whether it is currently on the flat or soft surface 400 to be cleaned, and thus the entire drive mechanism 22 will perform the corresponding action (on the flat surface 400, the drive mechanism 22 drives the push-pull component 222 to keep the blocking component 21 in the first raised position; on the soft surface 400, the drive mechanism 22 drives the push-pull component 222 to lower the blocking component 21 to the second position to block and seal the suction port 300).

[0149] The rolling element 212 is connected to the second bracket 12 via a bearing 71 and a connecting shaft 211, allowing it to rotate freely. One end of the pull rope 213 is connected to the connecting shaft 211, and the other end is connected to the first arm 201 of the crank 220. The second arm 202 of the crank 220 is rotatably connected (or hinged) to the blocking element 21, and the second arm 202 drives the blocking element 21 to perform a reset movement through the elastic force of the torsion spring 231.

[0150] After the cleaning equipment enters the soft surface 400 to be cleaned, its forward movement causes the rolling element 212 to rub against the lint on the surface 400. Under the influence of friction, the rolling element 212 drives the connecting shaft 211 to rotate, thereby tightening the pull rope 213. The tension of the pull rope 213 overcomes the elastic force of the torsion spring 231, causing the crank 220 to rotate. The crank 220 pulls down the shielding element 21 to seal the suction port 300. After exiting the soft surface 400, the rolling element 212 is suspended in the air without friction. The crank 220 returns to its original position due to the elastic force of the torsion spring 231, and the shielding element 21 is pulled to its first position.

[0151] The second embodiment of this utility model also provides a cleaning device, such as... Figure 1 as well as Figure 2As shown, the cleaning device includes a main body 100 and a roller brush module 00. Along a first direction, the roller brush module 00 is located at the bottom of the main body 100. Specifically, the bottom of the main body 100 may have a receiving cavity 110, in which the roller brush module 00 is installed. Along the forward direction of the cleaning device, the rear side wall of the receiving cavity 110 has a connecting opening 130 that communicates with the dust box. The roller brush module 00 includes a roller brush body 10 and a shielding assembly 20. The shielding member 21 of the shielding assembly 20 can form a suction chamber 500 communicating with the suction port 300 by surrounding the scraper strip 13. Thus, the airflow can enter the dust box in one sequence along the following path: suction port 300 → suction chamber 500 → gap between the roller brush 200 and the opening 103 → connecting opening 130 → dust box. The roller brush body 10 includes a cover component 104 and the roller brush 200. Along the first direction, in this embodiment, the horizontal plane of the first side 101 of the roller brush body 10 is higher than the horizontal plane of the second side 102. The cover component 104 is provided with an opening 103, and the roller brush 200 is installed in the opening 103. For other structural details of the roller brush module 00, please refer to the content provided in the first embodiment, which will not be repeated here.

[0152] In this embodiment, when the roller brush module 00 is installed at the bottom of the main body 100 of the cleaning equipment, in order to ensure that a suction port 300 for large particles of debris to pass through and enter the dust box can be formed between the roller brush module 00 and the hard, flat surface to be cleaned 400 (such as a wooden floor, cement floor, tile floor, etc.), the horizontal plane of the first side 101 must be higher than the horizontal plane of the second side 102 along the first direction. Therefore, the roller brush module 00 is tilted as a whole to form a larger suction port 300 between the first side 101 and the surface to be cleaned 400.

[0153] After the cleaning equipment enters a relatively rough and soft surface 400 to be cleaned (such as a carpet or blanket), in order to improve the dust removal efficiency of the cleaning equipment on the soft surface 400, the roller brush module 00 of this embodiment is also provided with a shielding component 20. The shielding member 21 of the shielding component 20 can be disposed on the first side 101, and the drive mechanism 22 is connected to the shielding member 21. The drive mechanism 22 is configured to drive the shielding member 21 to move up and down relative to the roller brush body 10 under the action of the friction force applied by the surface 400 to change the size of the suction port 300. Specifically, when the size of the suction port 300 is reduced, the obstruction member 21 decreases the gap between the roller brush module 00 and the soft surface to be cleaned 400. During the negative pressure operation of the dust box to vacuum the soft surface 400, the airflow flows faster and with greater force from the gap between the roller brush module 00 and the soft surface 400 towards the dust box. This allows the airflow to penetrate deeper into the surface (such as carpets or blankets), resulting in more efficient suction of dust particles from the soft surface 400 into the dust box. Secondly, with a smaller suction port 300, the space between the roller brush module 00 and the surface 400 is smaller, resulting in better sealing and vacuum. Therefore, without increasing the suction force, the suction force generated at the suction port 300 is greater, improving the dust removal efficiency of the cleaning equipment.

[0154] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0155] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0156] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
