Description

Technical Field

[0001] This application relates to the field of cleaning products, and in particular to hanging storage stands and cleaning tools. Background Technology

[0002] As people's living standards improve, dust collector rollers are becoming increasingly popular. A typical dust collector roller includes a handle for gripping, a fixed arm extending from the end of the handle, a core rotatably mounted on the fixed arm, and sticky paper wound around the core. During use, the sticky outer surface of the sticky paper cleans the target object; therefore, when storing it, it's necessary to prevent the sticky paper from contacting foreign objects to maintain its stickiness.

[0003] For example, Chinese patent document CN105658131A discloses a cover for a cleaning tool and a cleaning tool with a cover. The cover for the cleaning tool is characterized by having: an opening at one end in the axial direction; and a wall opening formed on a cylindrical body, which is formed with a predetermined width in the circumferential direction and extends at least from one end in the axial direction to the center, so that an adhesive tape roller supported by the cleaning tool can be received and released in the axial direction. The cylindrical body has: a lower track portion, which protrudes from the edge of the cylindrical wall forming the wall opening and extends at least along the center from one end in the axial direction, and is capable of sliding a flange portion; and an upper track portion, which is provided radially outward from the lower track portion relative to the lower track portion on the center portion side other than the axial end side of the lower track portion, and is capable of holding the flange portion between the upper track portion and the lower track portion.

[0004] The inventors discovered that this type of storage device has a weak ability to restrain cleaning tools. For example, when the cleaning tool is an adhesive dust roller, the dust paper is easy to stick to the inside of the storage device. Especially when the cleaning tool has a long handle, the cleaning tool may tip over, affecting the user experience, and there is room for improvement. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Reference Appendix Figure 1 and attached Figure 2 As shown, one embodiment of this application discloses a suspended storage base, including a cylindrical structure 100 and a positioning groove 200 disposed on the cylindrical structure 100.

[0024] Specifically, the cylindrical structure 100 has a bottom wall 110 abutting against the supporting surface and an opposite top wall 120 in the direction of gravity. The interior of the cylindrical structure 100 is hollow, forming a receiving space 300. The bottom wall 110 and the top wall 120 are connected by one or more connecting walls 130 to form the cylindrical structure 100. The cross-sectional shape of the cylindrical structure 100 can be approximately circular, rectangular, triangular, pentagonal, hexagonal, teardrop-shaped, horseshoe-shaped, etc. For example, see attached... Figure 2 In this structure, the bottom wall 110 and the top wall 120 are connected by two connecting walls 130 to form a cylindrical structure 100. From the bottom wall 110 to the top wall 120, the distance between the two connecting walls 130 gradually decreases. The bottom wall 110 is a flat planar structure to achieve a good fit with the supporting surface, and the top is an arc structure to provide a rounded appearance. The bottom wall 110, the top wall 120, and the connecting walls 130 are connected by arc transitions.

[0025] The positioning groove 200 is provided on the top wall 120 and opens away from the bottom wall 110. The positioning groove 200 extends axially in the cylindrical structure 100 and has a support section 210 and a guide section 230 that are interconnected. In the direction of gravity, the side wall of the support section 210 is convex relative to the top wall 120, and the side wall of the guide section 230 is concave relative to the support section 210. At least one end of the receiving space 300 is a first open end 301 for the entry of the adhesive paper roll 410. The side of the guide section 230 near the first open end 301 is a second open end 231. The support 430 of the adhesive paper roll 410 enters the guide section 230 and the support section 210 via the second open end 231. The bottom of the positioning groove 200 supports the support 430 to allow the adhesive paper roll 410 to hang within the receiving space 300. The sidewall of the guide section 230 allows the support 430 to swing relative to the cylindrical structure 100 to adjust the relative position of the adhesive paper roll 410 within the receiving space 300 (see attached). Figure 2 As shown by the curved arrow, where the solid black dot represents the swing axis of the bracket 430 (i.e., the location of the contact surface where the bracket and the positioning groove abut), the side wall of the support section 210 clamps the bracket 430 to achieve its upright position (i.e., to curb the swinging tendency mentioned above). The technical solution disclosed in this application achieves stable storage of the adhesive paper roll 410 through structural optimization of the storage base, especially the structural optimization of the positioning groove 200. Based on gravity suspension, the support section 210 and the bracket 430 work together to maintain its upright position, thus improving the user experience.

[0026] In this embodiment, both ends of the receiving space 300 are open, that is, both ends are first open ends 301. The positioning groove 200 is only open towards one of the first open ends 301, and the other end is closed to provide movement limit for the support 430. Furthermore, the closed part of the positioning groove 200 (that is, the end of the support section 210) is located in the middle of the cylindrical structure 100 in the axial direction.

[0027] For the specific structure of the positioning groove 200, please refer to the attached document. Figure 3 and attached Figure 4 In the illustrated embodiment, the positioning groove 200 further includes a transition section 220 disposed between the support section 210 and the guide section 230. In the direction of gravity, the sidewall of the transition section 220 gradually rises relative to the top wall 120 to connect the sidewalls of the support section 210 and the guide section 230. The sidewall of the transition section 220 transitions smoothly. In this embodiment, the only difference between the support section 210, the transition section 220, and the guide section 230 is the height of the sidewalls relative to the top; the spacing between the relative sidewalls of each section is uniformly set, meaning the opening size of the positioning groove 200 is uniformly set. For specific dimensions, see the attached drawing. Figure 4As shown, the groove depth H1 of the support section 210 is 1.5 to 3 times the groove depth H2 of the guide section 230. In the axial direction of the cylindrical structure 100, the extension length L1 of the support section 210 and the extension length L2 of the transition section 220 are close, with an L1:L2 ratio ranging from 0.7 to 1.3. The ratio between the extension length L3 of the guide section 230 and the extension length L2 of the transition section 220 ranges from 2 to 5.

[0028] The interaction between the positioning groove 200 and the cylindrical structure 100 can be found in the appendix. Figure 5 and attached Figure 6 In the illustrated embodiment, the sidewall of the guide segment 230 protrudes slightly beyond the top wall 120 in the direction of gravity. The bottom of the positioning groove 200 is flat, and in the direction of gravity, the bottom of the positioning groove 200 is lower than the top wall 120. Specifically, the distance D1 by which the sidewall of the guide segment 230 protrudes beyond the top wall 120 is 5% to 30% of the groove depth H1 of the support segment 210, that is, the sidewall of the guide segment 230 is basically flush with the top wall 120. In other embodiments, the sidewall of the guide segment 230 can be directly set to be flush with the top wall 120. In this setting, the bottom of the positioning groove 200 needs to be lower than the top wall 120 to provide a part for the bracket 430 to cooperate with. In other embodiments independent of the above, the bottom of the positioning groove 200 can be flush with the bottom surface of the top wall 120, that is, the positioning groove 200 is entirely set on the upper surface of the top wall 120. The height difference between the bottom of the positioning groove 200 and the bottom surface of the top wall 120 is to accommodate the gap S1 between the bracket 430 and the adhesive paper roll 410. (See attached diagram) Figure 5 In the middle, the stent 430 includes: Rotating section 431 extends axially in the cylindrical structure 100 to be rotatably engaged with rotating part 420; The bent section 432 extends from the receiving space 300 to the positioning slot 200; The support section 433 cooperates with the bottom of the positioning groove 200 to support itself; The upright section 434 cooperates with the support section 210 of the positioning groove 200 to achieve uprightness, and the handle 440 is installed on the upright section 434.

[0029] Furthermore, the rotating section 431, the bending section 432, and the supporting section 433 form a C-shaped structure, and at least a portion of the adhesive paper roll 410 is located within the opening of the C-shaped structure. The rotating section 431 and the supporting section 433 extend axially in the receiving space 300, while the upright section 434 and the bending section 432 extend in the direction of gravity.

[0030] Gap S1 is the gap between the bottom surface of the support section 433 and the adhesive surface 412 of the adhesive paper roll 410. During the process of the adhesive paper roll 410 entering the receiving space 300 along with the bracket 430, the top wall 120 and the positioning groove 200 enter the gap S1. The size of the gap S1 is allocated by the bottom of the positioning groove 200 into the gap S2 between the bottom surface of the support section 433 and the bottom of the positioning groove 200, and the gap S3 between the bottom of the positioning groove 200 and the adhesive surface 412 of the adhesive paper roll 410. (See attached diagram.) Figure 5 and attached Figure 6 It can be seen that the distribution of the gap S1 can vary with the height of the adhesive paper roll 410 relative to the storage base, that is, it allows a portion of the bracket 430 to protrude from the positioning groove 200 (in this embodiment, it allows a portion of the bracket 430 to protrude from the guide section 230), thereby allowing the bracket 430 to swing relative to the storage base to adjust the relative position of the adhesive paper roll 410 relative to the receiving space 300. In other words, when the adhesive surface 412 of the adhesive paper roll 410 approaches the bottom of the positioning groove 200, at least a portion of the support section 433 is exposed outside the positioning groove 200.

[0031] Reference Appendix Figure 4 As shown, in the axial direction of the cylindrical structure 100, the second open end 231 is recessed relative to the first open end 301, and the second open end 231 is in communication with the receiving space 300. The bracket 430 can extend into the receiving space 300 through the self-positioning groove 200 inside the storage base, thereby ensuring that the adhesive paper roll 410 and the bracket 430 are both located inside the storage base and are not exposed.

[0032] During the entry, exit, and oscillation of the adhesive paper roll 410 relative to the containment space 300, it may come into contact with the boundary of the containment space 300, resulting in adhesion. To overcome this problem, the following is attached to this application. Figure 2 In the illustrated embodiment, the inner circumferential surface of the cylindrical structure 100 is provided with an anti-adhesion strip 140 protruding outward toward the receiving space 300. The anti-adhesion strip 140 protrudes outward to reduce the contact area with the adhesive surface 412 of the adhesive paper roll 410, thereby reducing adhesion during contact. To provide a smooth operating feel, the anti-adhesion strip 140 extends axially in the cylindrical structure 100, i.e., in accordance with the direction of movement of the adhesive paper roll 410. Furthermore, multiple anti-adhesion strips 140 are provided, arranged side by side at intervals in the circumferential direction of the cylindrical structure 100.

[0033] In conjunction with the foregoing, one embodiment of this application also discloses a cleaning tool, including a dust removal roller 400 and the suspended storage base described in the above technical solution. The dust removal roller 400 includes: The dust removal paper roll 410 includes a core 411 and a plurality of dust removal paper wound on the core 411, the dust removal paper providing an adhesive surface 412 for dust removal; The rotating part 420 is inserted and positioned inside the core 411; The bracket 430 is rotatably fitted to the rotating part 420. The bracket 430 is fitted with the positioning groove 200 to allow the adhesive paper roll 410 to hang in the receiving space 300. The handle 440 is connected to the bracket 430, and the handle 440 has an adjustable length.

[0034] The dust removal roller 400 abuts against the support surface via the storage base. To reduce the impact between the storage base and the dust removal roller 400, as well as between the storage base and the support surface, multiple cushioning pads 111 are provided on the side of the bottom wall 110 of the cylindrical structure 100 facing away from the receiving space 300 (see Appendix). Figure 3 (As shown by the dashed line). In addition to providing cushioning, the cushioning feet 111 also provide greater friction to prevent the storage seat from moving when the user operates the dust removal roller 400.

[0035] In this embodiment, there is a cooperative relationship between the adjustable-length handle 440 and the storage base. In this application, the positioning reference is determined by the bracket 430, and the longer handle 440 will generate a larger moving torque relative to the bracket 430. In the previous embodiment, the positioning groove 200 can ensure that the overall center of gravity of the dust removal roller 400 is located within the projected area of ​​the storage base. In this embodiment, the length of the handle 440 can be actively controlled to eliminate the above-mentioned influence while expanding the application scenarios of the dust removal roller 400. For example, a shorter handle 440 is needed for cleaning clothes and desktops, while a longer handle 440 is needed for cleaning floors, walls, and windows.

[0036] For detailed settings of the controller 440, please refer to the attached document. Figure 7 and attached Figure 8 In the illustrated embodiment, the handle 440 includes at least two mutually rotatable rods 441 and a locking assembly disposed between the two rods 441. The locking assembly has an unlocked state that releases the axial relative movement of the two rods and a locked state. In one embodiment, the locking assembly includes a rotating member 442 and an expansion member 443 screwed together. When the rods 441 rotate relative to each other, the expansion member 443 moves on the rotating member 442. The thread of the rotating member 442 is tapered to expand or shrink the diameter of the expansion member 443, thereby locking and unlocking the axial position between the rods 441. Further details of the handle 440 can be found in the appendix. Figure 9 In the illustrated embodiment, the handle 440 includes at least two interlocking rods 441 and a connector 444 disposed between the two rods 441. One of the connector 444 and the rods 441 has a plurality of (e.g., 1 to 10) mating grooves 445 on its outer peripheral surface, and the other has a plurality of (e.g., 1 to 10) mating ribs 446. The mating grooves 445 and the mating ribs 446 extend axially. Multiple mating grooves 445 and mating ribs 446 may be provided, as shown in the attached figure. Figure 10 and attached Figure 11 As shown, there are three mating grooves 445, and the number of mating ribs 446 corresponds to the number of mating grooves 445. Each mating rib 446 is arranged side-by-side along the circumference of the rod 441, and each mating groove 445 is arranged side-by-side along the circumference of the connector 444. In other embodiments, both the mating groove 445 and the mating rib 446 are set to one corresponding groove. The quantitative relationship between the mating grooves 445 and the mating ribs 446 can be set as described above, i.e., one mating groove 445 mates with one mating rib 446, or it can be set as a one-to-many mating relationship, i.e., one mating rib 446 can mate with multiple mating grooves 445 according to the relative angle between the rod 441 and the connector 444. The outer diameter of the connector 444 is smaller than the inner diameter of the rod 441, and the two are tightly fitted only through the mating groove 445 and the mating rib 446. That is, there is a circumferential gap 447 between the connector 444 and the rod 441. This arrangement can reduce the insertion resistance of the rod 441 (gap fit) while improving the connection strength and overall integrity between the connector rods 441 (local tight fit). At the same time, the mating groove 445 and the mating rib 446, which extend axially, can withstand various stresses between the rods 441, thereby improving the overall strength.

[0037] For specific settings of the storage base, please refer to the detailed description above. Other settings not covered can be implemented using existing technologies, and will not be elaborated here.

[0038] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0039] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.

The outer diameter of the connector is smaller than the inner diameter of the rods, and the two are tightly fitted only through the mating grooves and the mating ribs.
