Description

Technical Field

[0001] This application relates to the field of cleaning, and in particular to a cleaning tool. Background Technology

[0002] Existing cleaning tools are mostly designed for cleaning smaller, softer items such as sofas, cat beds, dog beds, or beds. Therefore, these tools are generally small in size, with a base and handle that are typically at a horizontal angle, allowing users to push them horizontally. However, this design is not suitable for cleaning carpets. Carpets cover a larger area on the floor, requiring cleaning tools that are larger and have a more suitable operating angle.

[0003] Therefore, it is necessary to improve existing cleaning tools to avoid the aforementioned defects. Summary of the Invention

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0066] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0067] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative implementation of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0068] The present application will now be described in detail with reference to the accompanying drawings.

[0069] To solve the above technical problems, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A , Figure 5B , Figure 13 and Figure 14As shown, this application embodiment provides a cleaning tool, including a base 1, with a receiving cavity 12 inside the base 1. A first opening 13 is formed downwards on the base 1, communicating with the receiving cavity 12. The first opening 13 is formed along the width direction of the base 1. A dust collection structure 2 includes a dust collection body 21. Preferably, the dust collection body 21 is a hollow semi-cylindrical structure. Both ends of the dust collection body 21 are rotatably mounted on the end walls 113 of the base 1, thereby allowing the dust collection body 21 to be rotatably mounted within the receiving cavity 12. A dust collection chamber 211 is provided inside the dust collection body 21, and a dust collection port 212 is formed at the top of the dust collection body 21, communicating with the dust collection chamber 211. The dust collection body 21 rotates around its central axis. The dust collection surface 214 is the outer peripheral surface 213 of the dust collection body 21, and is a curved surface with the central axis of the dust collection body 21 as its axis. The dust-collecting surface 214 is at least partially exposed above the first opening 13, contacting the object to be cleaned. The dust-collecting surface 214 rolls back and forth to collect dust, hair, and other dirt from the carpet. A dust-removing structure 3 is also provided on the base 1, located at the first opening 13 and adjacent to the dust-collecting surface 214 of the dust-collecting body 21. When the dust-collecting surface 214 rolls back and forth, the dust-removing structure 3 scrapes the surface, drawing dirt from it into the dust-collecting chamber 211 through the dust-collecting port 212. The central axis of the handle 4 forms an angle with the tangent at the lowest point of the dust-collecting surface 214, with the angle set between 25 and 35 degrees. This distributes more of the force exerted by the user pushing and pulling the handle 4 horizontally, making it easier for the user to push and pull the cleaning tool. Additionally, this angle allows the handle 4 to have sufficient height for the user to use while standing. Preferably, the angle is set between 28 and 33 degrees; a smaller angle (e.g., closer to 25 degrees) results in a greater horizontal component of the force. When the included angle is set to 28-33 degrees, it can accommodate more horizontal force and a suitable handle height 4. In another preferred embodiment, the included angle is set to 30 degrees, which is suitable for the force application angle and height of most users. The ratio of the maximum length 42 of the handle 4 to the width 11 of the dust collection body 21 is greater than or equal to 4. The maximum length 42 of the handle 4 can be adjusted according to different user groups. For example, for users in Asia, the handle 4 is usually set to 1.2-1.3 meters; for users in Europe and America, since users in Europe and America are generally taller, the handle 4 is generally set to 1.4-1.5 meters. In this application, by widening the width of the dust collection body 21 and lengthening the length 42 of the handle 4, users can stand and hold the handle to clean larger areas of carpet.Compared to cleaning small areas like sofas or beds, cleaning large carpets can be challenging. If the handle isn't long enough, users have to bend or squat frequently to move the cleaning tool, which not only causes back pain but also significantly reduces cleaning efficiency. Furthermore, if the dust collection chamber isn't wide enough, the area covered during each rolling cleaning cycle is limited, requiring users to move the cleaning tool frequently, making it difficult to efficiently clean large carpets.

[0070] In one embodiment of this application, combined with Figure 2 , Figure 3 and Figure 4 As shown, the base 1 includes a first housing 15 and a second housing 16, which are arranged vertically. Multiple snap-fits are provided at the edge of one of the first housings 15 and 16, and multiple slots are provided at the edge of the other housing, allowing the first housing 15 and 16 to be snapped together. The first housing 15 includes a first frame portion 151 and a handle portion 152. Optionally, the handle portion 152 is a closed ring structure, and the handle 4 is directly connected and disposed within the ring structure. The handle portion 152 is integrally formed to enhance the connection strength between the handle portion 152 and the handle 4. The second housing 16 includes a second frame portion 161. The first frame portion 151 and the second frame portion 161 are assembled to form the main body portion 17 of the base 1, and a receiving cavity 12 is disposed within the main body portion 17. The base 1 is divided into a first housing 15 and a second housing 16, which not only reduces the difficulty of mold design for the base 1 but also makes the base 1 easier to disassemble and maintain.

[0071] In one embodiment of this application, combined with Figure 10 As shown, the handle 152 includes a first annular wall 1521, a second annular wall 1522, and a plurality of reinforcing ribs 1523. Optionally, both the first annular wall 1521 and the second annular wall 1522 are cylindrical structures, with the second annular wall 1522 fitted inside the first annular wall 1521, and the second annular wall 1522 and the first annular wall 1521 are spaced apart. The plurality of reinforcing ribs 1523 are connected and disposed between the first annular wall 1521 and the second annular wall 1522. Preferably, the plurality of reinforcing ribs 1523 are arranged radially around the first annular wall 1521. A connector is provided at the end of the handle 4. The connector can be a soft rubber plug that can be directly inserted into the second annular wall 1522; the connector can also be a joint with external threads, with the first annular wall 1521 having internal threads, and the connector is threadedly connected to the first annular wall 1521. The addition of multiple reinforcing ribs 1523 increases the strength of the connection between the handle 152 and the handle 4, making the cleaning tool of this application more robust and durable.

[0072] In one embodiment of this application, combined with Figure 2 , Figure 4 and Figure 5A As shown, the first housing 15 further includes a first extension 153, which extends obliquely rearward from the middle of the first frame portion 151. The second housing 16 further includes a second extension 162, which extends obliquely rearward from the middle of the second frame portion 161. The first extension 153 and the second extension 162 are joined to form the inclined span portion 18 of the base 1. The inclined span portion 18 includes a first end 181 and a second end 182. The first end 181 is connected to the handle portion 152. The handle 4, the handle portion 152, and the inclined span portion 18 are coaxially arranged, that is, the tilt angle of the inclined span portion 18 is the same as the tilt angle of the handle 4 as defined above. The second end 182 is connected to the main body portion 17. The width of the inclined span portion 18 gradually increases from the first end 181 to the second end 182, that is, a cross-section is formed from the first end 181 to the second end 182 of the inclined span portion 18. In this application, the first extension 153 and the second extension 162 roughly bisect each other to form the main body 17. The cross-section is then taken along the seam between the first extension 153 and the second extension 162. The width of the cross-section gradually increases from the first end 181 to the second end 182, resulting in a wider span portion 18 near the main body 17. This enhances the torsional and bending resistance of the span portion 18, thereby providing stronger support for the base 1.

[0073] In one embodiment of this application, combined with Figure 2 , Figure 4 and Figure 5A As shown, the diagonal span 18 includes a first side surface 183 and a second side surface 184, which intersect with the cross-section. The first extension 153 and the second extension 162 are joined in an vertical position, with the first side surface 183 and the second side surface 184 located at the seam between the first extension 153 and the second extension 162. Optionally, the first side surface 183 and the second side surface 184 are curved surfaces. Considering that the width of the cross-section gradually increases from the first end 181 to the second end 182, the first side surface 183 and the second side surface 184 are two curved surfaces with opposite curvatures. Setting the first side surface 183 and the second side surface 184 as curved surfaces can better distribute the force on the diagonal span 18, further enhancing the impact resistance of the diagonal span 18. In another embodiment, the first side surface 183 and the second side surface 184 can also be roughly planar, in which case the first side surface 183 and the second side surface 184 can be directly connected diagonally to the handle 152 and the main body 17 in a V-shape.

[0074] In one embodiment of this application, combined with Figure 2 , Figure 3 and Figure 4As shown, the first frame portion 151, the first extension portion 153, and the handle portion 152 are integrally formed, thereby ensuring a seamless connection between them and reducing the risk of loosening or breakage. Simultaneously, the second frame portion 161 and the second handle portion 152 are also integrally formed, further optimizing the structural integrity of the base 1; that is, only two molds need to be developed during the production of the base 1.

[0075] In one embodiment of this application, combined with Figure 5A , Figure 5B As shown, the base 1 includes at least one limiting surface 19. The dust collection body 21 rotates around its central axis, and the limiting surface 19 can limit the rotation angle of the dust collection body 21 to less than 360 degrees, meaning that the dust collection body 21 rolls back and forth around the central axis during cleaning. Optionally, the limiting surface 19 is located above the dust collection body 21, and the length of the perpendicular segment between the limiting surface 19 and the central axis is less than the rotation radius of the dust collection body 21. Thus, the limiting surface 19 can limit the dust collection body 21, preventing excessive rotation or shaking during rotation, and especially preventing excessive rotation of the dust collection body 21 from spilling dirt from the first opening 13 out of the dust collection chamber 211. It is understood that the limiting surface 19 can be located on the base 1 or on the cover 117, as long as it can limit the dust collection body 21.

[0076] In one embodiment of this application, combined with Figure 3 , Figure 6A , Figure 6B and Figure 7 As shown, the base 1 includes a top wall 110, which extends toward the dust collector 21 and is provided with at least one flat, arc-shaped boss 111. The boss 111 is located on the rotation path of the dust collector 21. Optionally, the boss 111 is formed along the circumferential direction of the dust collector 21, with the curvature decreasing at the highest point in the circumferential direction. The limiting surface 19 is set as the bottom surface 1111 of the boss 111, thereby limiting the dust collector 21. Optionally, a second opening 14 is provided on the top wall 110 for emptying the dirt in the dust collection chamber 211, so the boss 111 can be selectively provided at both ends of the top wall 110. Preferably, there are two bosses 111, that is, bosses 111 are provided at both ends of the top wall 110. The two bosses 111 can simultaneously limit both ends of the dust collector 21 to maintain stability. It is understood that the boss 111 in this application also participates in forming the receiving cavity 12, so there is no need to set other limiting structures after forming the receiving cavity 12.

[0077] In one embodiment of this application, combined with Figure 7As shown, a sound-absorbing strip 112 is provided on the limiting surface 19, and the sound-absorbing strip is arranged along the circumferential direction of the limiting surface 19. Optionally, a receiving groove is provided on the limiting surface 19, and the sound-absorbing strip 112 is disposed in the receiving groove, and is at least partially exposed. When the dust collector 21 rotates to its limit angle, the dust collector 21 abuts against the sound-absorbing strip 112. The sound-absorbing strip 112 can be an air strip or a flexible silicone strip.

[0078] In one embodiment of this application, combined with Figure 2 As shown, the base 1 also includes a cover 117. The base 1 has a second opening 14 facing upwards, which communicates with the receiving cavity 12. Dirt in the dust collection body 21 is poured out through the second opening 14. The cover 117 is movably mounted on the second opening 14 to seal or open it. Preferably, the top wall 110 of the base 1 and the cover 117 are also designed as flat arc shapes, which makes the entire cleaning tool look more refined and modern. This also reduces the height of the base 1, allowing it to enter and exit lower areas, such as under beds and sofas. Furthermore, when the top wall 110 of the base 1 is a relatively flat arc shape, it can also directly limit the position of the dust collection body 21.

[0079] In one embodiment of this application, combined with Figure 12 As shown, the dust collection structure 2 also includes two auxiliary wheels 114. The base 1 includes two end walls 113 and two end caps 115, which are respectively placed on the two end walls 113 to form two receiving cavities. The two auxiliary wheels 114 are rotatably mounted on the two end walls 113 and are located in the two receiving cavities. The distance by which the lowest point of the auxiliary wheel 114 extends beyond the first opening 13 is 2-3 mm greater than the distance by which the lowest point of the dust collection surface 214 extends beyond the first opening 13. During cleaning, because the carpet has a certain degree of flexibility but is not too soft, the auxiliary wheel 114 will first contact the carpet and then sink down, allowing the dust collection surface 214 to subsequently contact the carpet. The 2-3 mm range ensures that the dust collection surface 214 is not too high and can maintain contact with the carpet.

[0080] In one embodiment of this application, combined with Figure 3 and Figure 11As shown, the dust collection structure 2 also includes at least one flexible protrusion 22. The protrusion 22 includes a third end 221 and a fourth end 222. The third end 221 is disposed on the dust collection surface 214, and the fourth end 222 extends away from the dust collection surface 214. The thickness of the protrusion 22 decreases in a stepped manner from the third end 221 to the fourth end 222. That is, the protrusion 22 includes a front side 223 and a rear side 224. Both the front side 223 and the rear side 224 are set in a stepped shape, and the front side 223 and the rear side 224 are close to each other from the third end 221 to the fourth end 222, which reduces the thickness of the protrusion 22. The stepped reduction in the thickness of the protrusion 22 gives the protrusion 22 sufficient rigidity to generate friction with the carpet to assist the rotation of the dust collection body 21. Preferably, the front side 223 and the rear side 224 are configured as at least two continuous stepped layers. When the rib 22 bends, at least a portion of the front side 223 and the rear side 224 can avoid contact with the carpet, thus preventing excessive friction between the rib 22 and the carpet, making it difficult for the user to push the cleaning tool. Optionally, the third end 221 of the rib 22 extends and is provided with a snap-fit ​​groove 225, which penetrates and snaps onto the dust collection surface 214 for assembling the rib 22. In this application, the number of ribs 22 is set to multiple, and the multiple ribs 22 are arranged along the width direction of the base 1 on the dust collection surface 214.

[0081] In one embodiment of this application, combined with Figure 5B As shown, the dust collection surface 214 includes a front dust collection area 2141, a rear dust collection area 2142, and bristles 215 respectively disposed on the front dust collection area 2141 and the rear dust collection area 2142. The bristles 215 on the front dust collection area 2141 are arranged obliquely upward, so that when the dust collection body 21 rotates backward, the bristles 215 on the front dust collection area 2141 generate friction with the carpet, which can capture dirt on the carpet. The front dust collection body 31 includes a front dust collection surface 311, which is curved and disposed close to the front dust collection area 2141, and bristles 215 are disposed on the front dust collection surface 311. The bristles 215 on the front dust collection surface 311 are obliquely upward toward the front dust collection area 2141, so that dirt on the bristles 215 on the front dust collection area 2141 can be carried into the dust collection chamber 211. Similarly, the bristles 215 on the rear dust removal area 2142 are angled upwards, so that when the dust collection body 21 rotates forward, the bristles 215 on the rear dust removal area 2142 generate friction with the carpet, which can capture dirt on the carpet. The rear dust removal body 32 includes a rear dust removal surface 321, which is curved and close to the rear dust removal area 2142. The rear dust removal area 2142 is provided with bristles 215, which are angled upwards towards the rear dust removal area 2142. This allows dirt on the bristles 215 on the rear dust removal area 2142 to be carried into the dust collection chamber 211.

[0082] In one embodiment of this application, combined with Figure 5B As shown, the dust collection structure 2 also includes at least one flexible protrusion 22, which is positioned in the middle of the dust collection surface 214, dividing the dust collection surface 214 into a front dust collection area 2141 and a rear dust collection area 2142. When the dust collection body 21 rotates to its limit position, the protrusion 22 contacts the front dust collection body 31 or the rear dust collection body 32. Thus, the protrusion 22 can also limit the rotation of the dust collection body 21.

[0083] The following is a comprehensive explanation of how to use the cleaning tool. When the user pushes the cleaning tool forward, the protrusion 22 bends backward and generates friction with the carpet, causing the dust collection body 21 to rotate backward. At this time, the bristles 215 on the rear dust collection area 2142 capture dust, pet hair, and other dirt from the carpet. When the dust collection body 21 rotates to its limit position, the boss 111 limits the dust collection body 21, and the protrusion 22 also simultaneously limits its position against the rear dust collection body 32. When the user pushes the cleaning tool backward again, the protrusion 22 bends forward and generates friction with the carpet, causing the dust collection body 21 to rotate forward. At this time, the bristles 215 on the rear dust collection surface 321 scrape the rear dust collection area 2142, capturing dirt onto the bristles 215 on the rear dust collection surface 321, while simultaneously the bristles 215 on the front dust collection area 2141 capture dirt from the carpet. When the dust collection body 21 rotates forward to its limit position, the boss 111 limits the dust collection body 21, and the protrusion 22 also limits the front dust collection body 31 at the same time. Repeating the rolling process again, the rear edge 2122 of the dust collection port 212 scrapes the rear dust collection surface 321 to collect dirt into the dust collection chamber 211, and the bristles 215 on the front dust collection surface 311 scrapes the front dust collection area 2141 to capture dirt onto the bristles 215 of the front dust collection surface 311. Similarly, during the repeated back-and-forth rolling process, the front edge 2121 of the dust collection port 212 scrapes the front dust collection surface 311 to collect dirt into the dust collection chamber 211. By repeating the above process, the cleaning tool can continuously clean dirt from the carpet.

[0084] In one embodiment of this application, combined with Figure 2 and Figure 8As shown, the cleaning tool also includes a cover 117. A second opening 14 is provided on the base 1 facing upwards. The second opening 14 communicates with the receiving cavity 12. The cover 117 is movably disposed on the second opening 14 for selectively sealing the second opening 14. It is understood that both the second opening 14 and the cover 117 are located on the first frame portion 151. The cover 117 includes a connecting end 1171 and a free end 1172. The connecting end 1171 is rotatably connected to the base 1, wherein the rotatable connection can be achieved through a rotating shaft 120. A button structure 116 is used to lock or release the free end 1172 of the cover 117. The button structure 116 includes a button 1161, which is disposed on the first extension portion 153. When the user presses the button 1161, the button structure 116 releases the free end 1172 of the cover 117. At this time, the cover 117 opens the second opening 14, allowing the user to empty the dirt from the dust collection chamber 211 through the second opening 14. The button structure 116 prevents the cover 117 from being opened due to impact during cleaning, thus preventing dirt from spilling out.

[0085] In one embodiment of this application, combined with Figure 8 and Figure 9 As shown, the button structure 116 includes a mounting base 1162, which is disposed in the base 1. Further, the mounting base 1162 is disposed within the inner cavity of the inclined portion 18 of the base 1, and is connected to the inclined portion 18 by fasteners. The mounting base 1162 has two relatively spaced upright plates 11621, forming a groove 11622 between them. The locking tongue 1163 is slidably disposed on the mounting base 1162, that is, the locking tongue 1163 is slidably disposed in the groove 11622. A latch 11721 is provided on the free end 1172 of the cover 117, and one end of the locking tongue 1163 presses to lock the latch 11721. A connecting structure 11631 extends downward from the latch 1163. A slot is provided on the mounting base 1162, and the connecting structure 11631 is located in the slot. One end of the elastic element 1164 is connected to the connecting structure 11631, and the other end abuts against the slot wall. The bottom of the button 1161 extends to form an inclined guide structure 11611. A guide hole 11632 is provided on the latch 1163, and the guide structure 11611 is inserted into the guide hole 11632. When the button 1161 is pressed, the guide structure 11611 moves downward, driving the latch 1163 to move backward and compress the elastic element 1164. At this time, the latch 1163 moves backward to release the latch 11721, and the cover 117 opens the second opening 14.

[0086] In one embodiment of this application, combined with Figure 2 , Figure 8 and Figure 12As shown, the connecting end 1171 of the cover 117 is rotatably connected to the base 1 via a rotating shaft 120. At least one torsion spring 121 is fitted onto the rotating shaft 120, with one end of the torsion spring 121 connected to the cover 1177 and the other end connected to the base 1. The torsion spring 121 provides a preload force for the opening and closing action of the cover 117, meaning the torsion spring 121 has a pre-set elastic force. When the button structure 116 releases the free end 1172 of the cover 117, the torsion spring 121 drives the cover 117 to rotate and open. The base 1 also includes at least one protrusion 122, which is located at the second opening 14. A shaft sleeve is provided on the connecting end 1171 of the cover 117, which is sleeved on the rotating shaft 120. The protrusion 122 is positioned relative to the shaft sleeve of the cover 117. During the opening of the cover 117, the protrusion 122 generates resistance by friction against the shaft sleeve. Preferably, the preload of the torsion spring 121 is set to match the resistance generated by the protrusion 122, which enables the cover 117 to open slowly and avoids damage to the cover 117 due to sudden impact.

[0087] In one embodiment of this application, the cleaning tool does not involve any electrical circuits; that is, the cleaning tool performs the cleaning task through mechanical structures and physical principles. Since no electrical circuits are involved, there are no safety hazards caused by electrical faults, short circuits, or leakage.

[0088] In one embodiment of this application, combined with Figure 12 As shown, it also includes a lever 23, which is disposed within the dust collection chamber 211 and can slide along the width of the dust collection chamber 211. One implementation involves a slider on the lever 23 and a groove 11622 within the dust collection chamber 211. The lever 23 slides through the cooperation of the slider and the groove 11622. The shape of the lever 23 is adapted to the vertical cross-section of the dust collection chamber 211, allowing it to push and gather dirt from one end of the dust collection chamber 211 to the other end, making it easier for the user to empty the dirt into the trash can.

[0089] In one embodiment of this application, combined with Figure 12 As shown, it also includes an anti-collision strip 118. The base 1 includes a front sidewall 119. When the base 1 moves forward, the front sidewall 119 is prone to hitting furniture, walls, etc. Therefore, an anti-collision strip 118 is provided on the front sidewall 119 along its width direction. The anti-collision strip 118 is set in a long strip shape, and the anti-collision strip 118 can be supported by flexible materials such as silicone and rubber, which can prevent the front sidewall 119 from hitting furniture, walls, etc. and making noise, and can also protect the front sidewall 119 from damage.

[0090] In one embodiment of this application, combined with Figure 1As shown, the handle 4 includes multiple connecting sections 41, which are detachably connected. The detachable connection can be a threaded connection or an interference fit, allowing the user to adjust the length of the handle 4 according to their height and facilitating disassembly and transportation. Alternatively, the multiple connecting sections 41 of the handle 4 can also be telescopically connected.

[0091] In one embodiment of this application, combined with Figure 1 As shown, the handle 4 and the base 1 are fixedly connected, and the angle between the central axis of the handle 4 and the tangent at the lowest point of the dust collection surface 214 is also a fixed angle. The fixed connection between the handle 4 and the base 1 increases the connection strength. During actual use of the cleaning tool, a certain amount of friction is required between the dust collection surface 214 and the carpet to produce a cleaning effect. If the handle 4 and the base 1 are not fixedly connected, the relative displacement between them will occur frequently under the action of friction, making it difficult for the user to push the cleaning tool and causing inconvenience.

[0092] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
