Description

Technical Field

[0001] This utility model relates to the field of sponge rollers, and specifically to a sponge roller that is easy to clean. Background Technology

[0002] A sponge roller (AQN) is a type of sponge. A sponge absorbent roller is a multi-microporous material with interconnected micropores, which has good water absorption and corrosion resistance. It is usually composed of sponge, glue, abrasive, processing technology and other materials.

[0003] A search revealed a utility model of an easy-to-clean sponge roller with announcement number CN219115009U. The roller includes a roller body, a sponge block, a quick-release mechanism, and a rinsing mechanism. Side rings are fixedly installed at both ends of the roller body, and grooves are formed between the roller body and the side rings. This utility model allows for cleaning by pulling a retaining plate forward and backward, moving it outward within the groove, and simultaneously moving the upper and lower side plates outward within the side grooves. This compresses a spring, generating potential energy, and simultaneously disengages the retaining plate from the grooves on both sides of the sponge block. Water is then directly injected into the water tank. The water flows through water injection holes on the side walls of the grooves into the side openings on both sides of the sponge block. The water wets any residual printing material inside the sponge block, causing it to float to the surface and be washed away by the water flow. This allows for cleaning without disassembling the sponge block installed on the surface of the roller body, achieving a highly efficient cleaning effect.

[0004] Existing sponge rollers have surfaces covered with tiny pores that are easily clogged when absorbing water, oil, or other stains. Cleaning typically involves simply rinsing the roller with water, which is insufficient for thorough cleaning. Manual wiping with a cleaning brush is also necessary, which is cumbersome and laborious. While the easy-to-clean sponge roller in the comparative example above facilitates sponge block disassembly and includes water inlets for cleaning, this comparative example requires disassembling multiple sponge blocks for cleaning, which is both time-consuming and inconvenient.

[0005] Therefore, it is necessary to invent a sponge roller that is easy to clean to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sponge roller that is easy to clean. Two sets of clamps are fitted onto the connectors at both ends of the rubber sleeve, and then fastened with fasteners. The brush head inside the connecting frame is then pressed tightly against the outside of the rubber sleeve. The connectors and the rubber sleeve are then rotated, but the connectors and clamps are rotatable, so rotating the connectors does not cause the connecting frame to rotate. Water is then sprayed onto the outside of the rubber sleeve, and the telescopic rod above the brush head, combined with the external second spring, presses the brush head firmly against the outside of the rubber sleeve, making it easy to clean away dirt. When cleaning is no longer needed, the cleaning mechanism can be directly removed. This solves the problem mentioned in the background art: existing sponge rollers have surfaces covered with tiny pores that are easily clogged when absorbing water, oil, or other dirt. Cleaning usually involves simply rinsing the sponge roller with water, which is insufficient for thorough cleaning. Manual wiping with a cleaning brush is also required, which is not only cumbersome but also laborious and inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sponge roller that is easy to clean, including a rubber sleeve;

[0008] Connectors are installed at both ends of the rubber sleeve for assembly. Limiting grooves are formed on the inner surface of the rubber sleeve. A PVC inner tube is movably sleeved inside the rubber sleeve. Rubber cotton is pasted on both sides of the PVC inner tube. Slots are formed on both sides of the inner surface of the PVC inner tube.

[0009] A limiting component, located inside the connector, is used for limiting installation;

[0010] A cleaning mechanism is fitted on both sides of the connector for easy cleaning. The cleaning mechanism includes a clamp, which is fitted on the outside of the connector. The clamp has a fastener connected to its internal thread. A connecting frame is fixedly connected above the clamp. Telescopic rods are slidably connected inside the connecting frame. A second spring is fitted on the outside of the telescopic rod. A fixing plate is fixedly connected to the lower end of the telescopic rod. A brush head is provided below the fixing plate.

[0011] Preferably, the limiting component includes a limiting post, which is movably sleeved on both sides inside the connector. The limiting post has a cavity inside and a first spring is provided inside. The lower end of the first spring is fixedly connected to a connecting plate, and limiting blocks are fixedly connected to the lower sides of the connecting plate.

[0012] Preferably, the limiting blocks are provided in two sets, and the two sets of limiting blocks are fixedly connected to both sides of the connecting plate.

[0013] Preferably, the limiting groove inside the rubber sleeve is slidably connected to the slider outside the PVC inner tube, and the slider is T-shaped.

[0014] Preferably, the clamp and the connector are movably connected, and the connecting frame is U-shaped.

[0015] Preferably, the telescopic rod is provided in three sets, and the three sets of telescopic rods are movably connected to the connecting frame, with the second spring located outside the telescopic rod and below the connecting frame.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. The cleaning mechanism facilitates cleaning of the rubber sleeve surface. Two sets of clamps are fitted onto the connectors at both ends of the rubber sleeve and then fixed with fasteners. The brush head inside the connector is then pressed against the outside of the rubber sleeve. The connector and the rubber sleeve are rotated, but the connector and clamps can rotate, so rotating the connector will not cause the connector to rotate. Water is then sprayed onto the outside of the rubber sleeve. The telescopic rod above the brush head and the external second spring push back and squeeze, making the brush head press tightly against the outside of the rubber sleeve. This makes it easy to clean the dirt on the outside of the rubber sleeve. When cleaning is no longer needed, the cleaning mechanism can be removed directly.

[0018] 2. The design of the connector and limiting components facilitates the disassembly of the rubber sleeve. The rubber sleeve is placed over the PVC inner tube, and then the connector is inserted into both ends of the PVC inner tube. Next, the limiting block on the outside of the limiting post is pressed to squeeze the connecting plate and the first spring on the rear side, causing the limiting block on the other side of the connecting plate to extend and retract into the limiting post. Then, the connector is inserted into the upper and lower sides. When it is inserted to the bottom, the limiting block is released. The first spring on the rear side of the connecting plate rebounds and pushes the limiting block on the other side of the connecting plate into the slot inside the PVC inner tube for limiting installation.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-5 The illustrated sponge roller is easy to clean and includes a rubber sleeve 1;

[0030] Connector 3 is installed at both ends of rubber sleeve 1 for assembly. Limiting grooves 2 are opened on the inner surface of rubber sleeve 1. PVC inner tube 5 is movably sleeved inside rubber sleeve 1. Rubber cotton 7 is pasted on both sides of PVC inner tube 5. Slots 8 are opened on both sides of the inner surface of PVC inner tube 5.

[0031] Limiting component 4 is located inside connector 3 and is used for limiting installation;

[0032] A cleaning mechanism 9, sleeved on both sides of the connector 3, facilitates cleaning. The cleaning mechanism 9 includes clamps 901, which are sleeved on the outside of the connector 3. Fasteners 902 are threaded into the inside of the clamps 901. A connecting frame 903 is fixedly connected above the clamps 901. Telescopic rods 904 are slidably connected inside the connecting frame 903. Second springs 905 are sleeved on the outside of the telescopic rods 904. A fixing plate 906 is fixedly connected to the lower end of the telescopic rods 904. Brush heads 907 are provided below the fixing plates 906. The two sets of clamps 901 are connected by sleeves on both ends of the rubber sleeve 1. On part 3, fix it with fastener 902, then make the brush head 907 inside the connecting bracket 903 fit tightly against the outside of the rubber sleeve 1. Then rotate the connecting part 3 and the rubber sleeve 1. The connecting part 3 and the clamp 901 can rotate, so rotating the connecting part 3 will not drive the connecting bracket 903 to rotate together. Then spray water on the outside of the rubber sleeve 1. With the help of the telescopic rod 904 above the brush head 907 and the external second spring 905, the brush head 907 is pressed tightly against the outside of the rubber sleeve 1, which makes it easy to clean the stains on the outside of the rubber sleeve 1. When cleaning is not needed, the cleaning mechanism 9 can be removed directly.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting component 4 includes a limiting post 401, which is movably sleeved on both sides inside the connector 3. A cavity 402 is opened inside the limiting post 401, and a first spring 403 is provided inside the limiting post 401. A connecting plate 404 is fixedly connected to the lower end of the first spring 403. Limiting blocks 405 are fixedly connected to the lower two sides of the connecting plate 404. The connecting plate 3 is then inserted into the PVC inner tube 5 through a rubber sleeve 1. The connector 3 is then inserted into both ends of the PVC inner tube 5. The limiting blocks 405 outside the limiting post 401 are pressed to squeeze the connecting plate 404 and the first spring 403 on the rear side, so that the limiting block 405 on the other side of the connecting plate 404 extends and retracts into the limiting post 401. Then, the connector 3 is inserted into the upper and lower sides. When it is inserted to the bottom, the limiting block 405 is released. The first spring 403 on the rear side of the connecting plate 404 rebounds and pushes the limiting block 405 on the other side of the connecting plate 404 into the slot 8 inside the PVC inner tube 5 for limiting installation.

[0034] like Figure 4 As shown, there are two sets of limiting blocks 405. The two sets of limiting blocks 405 are fixedly connected to both sides of the connecting plate 404. One set of limiting blocks 405 is used for pressing. When pressed, it drives the connecting plate 404 to extend and retract. After the connecting plate 404 extends and retracts, it drives the other limiting block 405. The other limiting block 405 is inserted into the slot 8 inside the PVC inner tube 5 to limit the installation of the connecting piece 3 and the PVC inner tube 5.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the limiting groove 2 inside the rubber sleeve 1 is slidably connected to the slider 6 outside the PVC inner tube 5. The slider 6 is T-shaped. The limiting groove 2 inside the rubber sleeve 1 can limit and lock the slider 6 outside the PVC inner tube 5, thereby strengthening the installation between the rubber sleeve 1 and the PVC inner tube 5 and preventing loosening during use.

[0036] like Figure 1 and Figure 6 As shown, clamp 901 is movably connected to connector 3, and connector 903 is U-shaped. Since clamp 901 is fitted onto connector 3 to fix connector 903, and clamp 901 and connector 3 are not fixedly connected, clamp 901 and connector 903 will not rotate when connector 3 and rubber sleeve 1 rotate.

[0037] like Figure 6 As shown, the telescopic rod 904 is provided in three sets. The three sets of telescopic rods 904 are movably connected to the connecting frame 903. The second spring 905 is located outside the telescopic rod 904 and below the connecting frame 903. Through the rebound action of the second spring 905 outside the telescopic rod 904, the telescopic rod 904 can be pushed to press tightly against the fixed plate 906 and brush head 907 below the rubber sleeve 1, thereby facilitating the cleaning of the outside of the rubber sleeve 1.

[0038] The working principle of this utility model is as follows: First, align the limiting groove 2 below the rubber sleeve 1 with the slider 6 outside the PVC inner tube 5, so that the rubber sleeve 1 is fitted onto the outside of the PVC inner tube 5. Then, respectively, insert the two sets of connectors 3 into the inner sides of both ends of the PVC inner tube 5. Next, press the limiting block 405 outside the limiting post 401 to compress the connecting plate 404 and the first spring 403 on the rear side, causing the limiting block 405 on the other side of the connecting plate 404 to extend and retract into the limiting post 401. Then, insert the connector 3 into the upper and lower sides. When it is inserted to the bottom, release the limiting block 405. The first spring 403 on the rear side of the connecting plate 404 will rebound and push the limiting block 405 on the other side of the connecting plate 404 into the slot 8 inside the PVC inner tube 5 for limiting and installation. After assembly, By fitting two sets of clamps 901 onto the connectors 3 at both ends of the rubber sleeve 1, and then fixing them with fasteners 902, the brush head 907 inside the connecting frame 903 is then pressed against the outside of the rubber sleeve 1. The connecting frame 3 and the rubber sleeve 1 are then rotated. The connecting frame 903 will not rotate when the connecting frame 901 is rotated, as the connecting frame 901 can rotate. Water is then sprayed onto the outside of the rubber sleeve 1. The telescopic rod 904 above the brush head 907 and the external second spring 905 rebound and squeeze, making the brush head 907 press tightly against the outside of the rubber sleeve 1. This makes it easy to clean the stains on the outside of the rubber sleeve 1. When cleaning is no longer needed, the cleaning mechanism 9 can be removed by following the steps above. This completes the process of using the easy-to-clean sponge roller.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
