Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a multifunctional wiper. Background Technology

[0002] Wiping devices have gained popularity due to their simple structure and efficient and convenient cleaning process. Existing wiping devices have roughly similar structures, including a wiping body, a wiping agent on the back of the wiping body, and a handle that is rotatably connected to the front of the wiping body. People use the handle to clean surfaces such as window glass or walls.

[0003] The following drawbacks exist in the market for cleaning wipes: Traditional wipes typically only have a single wiping function, requiring the use of other tools (such as squeegees) to complete complex cleaning tasks, resulting in low cleaning efficiency. For example, after wiping glass or smooth surfaces, a squeegee is needed to remove residual water or dirt, making the operation cumbersome and requiring frequent tool switching. Furthermore, existing wipes often use binding, adhesive, or clip-on designs to secure the wiping material (such as a cloth), which is prone to insecure fixing and inconvenient to replace. Users must manually disassemble parts or replace the wiping material, which is time-consuming and laborious, especially in high-frequency cleaning scenarios, significantly reducing work efficiency. Additionally, installing and removing the wiping material requires direct hand contact. Due to frequent use, the wiping material accumulates dirt and grime, easily contaminating the user's hands with stains and germs, severely impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional wiper that eliminates the need for direct hand operation when installing and replacing wipes. It also allows the use of a scraper to remove residual water stains or dirt, making it simple, convenient, time-saving, and labor-saving. Furthermore, it avoids contact between the hands and the dirt and germs on the wipes, thus enhancing the user experience.

[0005] To achieve the above objectives, this utility model provides the following solution:

The clamping frames are connected to a first elastic member. The bottom cover has a first snap-fit ​​part. A wiping object is placed below the bottom surface of the bottom cover. The top cover has a second snap-fit ​​part. When the top cover is pressed down, the first snap-fit ​​part and the second snap-fit ​​part snap together, and the clamping frame is squeezed by the oblique force of the top cover or the bottom cover, which compresses the first elastic member and causes the clamping frame to move closer to the center of the bottom cover to clamp the wiping object. When the first snap-fit ​​part and the second snap-fit ​​part are released, the first elastic member causes the clamping frame to move away from the center of the bottom cover to release the wiping object.

[0035] The present invention achieves the following beneficial technical effects compared to the prior art:

[0036] 1. This utility model provides a multifunctional wiper. In its natural state, a first locking block is positioned above a first locking groove, and a second locking block is positioned above a second locking groove. When the top cover is pressed down, the spring-loaded frame moves downward. As the first and second spring-loaded blocks move downward with the spring-loaded frame, the slope of the first locking block abuts against the first locking groove and moves downward, and the slope of the second locking block abuts against the second locking groove and moves downward. At this time, the first and second springs are compressed. When the upper edge of the first locking block is engaged in the first locking groove, and the upper edge of the second locking block is engaged in the second locking groove, the top cover stops moving downward. Simultaneously, the downward movement of the top cover drives the push plate on the top cover to move downward. The clamping frame is compressed by the oblique force of the push plate, causing the deformation spring to be compressed, and the first clamping tooth on the clamping frame to move towards the second clamping tooth, thereby achieving clamping of the object to be wiped. When the first and second rebound buttons are simultaneously pressed and moved towards each other near the center of the bottom cover, the first and second rebound blocks move in opposite directions, compressing the first and second springs. This causes the first locking block and the second locking block to disengage from their respective slots, resulting in the rebound frame moving upwards and consequently the top cover moving upwards. The upward movement of the top cover then causes the push plate to move upwards, gradually disengaging from the sliding block. The spring force of the deformation spring causes the sliding plate to move away from the center of the bottom cover, which in turn causes the first clamping tooth to move away from the second clamping tooth, causing the cleaning agent to fall off. This eliminates the need for direct hand operation when installing and replacing the cleaning agent. Simply press down on the top cover to install the agent, and press the first and second rebound buttons by hand to remove it. This is simple, convenient, time-saving, and labor-saving, avoiding contact with dirt and germs on the cleaning agent and enhancing the user experience.

[0037] 2. The multi-functional wiper provided by this utility model has a top cover with a scraper strip connected to the four sides of the front. The scraper strip is made of soft rubber and is formed by secondary injection molding around the top surface of the top cover, ensuring the connection stability of the scraper strip. By setting the scraper strip around the four sides, after wiping the surface, some water stains are usually left on the surface. The wiper can be turned over and the scraper strip can be used to remove the water stains. In addition, since the scraper strip is set around the top cover, it can better fit the corners of the surface being wiped, making wiping more convenient and time-saving. The handle also includes a first extension rod, a second extension rod, and a sleeve, realizing the length adjustment of the handle to adapt to the needs of operators of different heights or usage scenarios. The handle also includes a clamping component for clamping the wiped dirt, avoiding picking it up by hand, which is more hygienic. By setting a hanging rope, it is easier to hang the wiper on an external wall, reducing the use of space and making it more convenient to take out. Attached Figure Description

Detailed Implementation

[0059] First Embodiment

[0060] This embodiment provides a multifunctional wiper, such as Figures 1-13 As shown, it includes a wiping body 1 and a handheld part 6. The wiping body 1 is rectangular, and the handheld part 6 is movably connected to the front of the wiping body 1, so that the handheld part 6 can be rotated to a suitable angle for wiping operation as needed. The wiping body 1 includes a top cover 3 and a bottom cover 2 connected by a gap, providing a space for the relative movement of the top cover 3 relative to the bottom cover 2. The bottom surface of the bottom cover 2 is provided with a wiping material. The two ends of the bottom cover 2 are slidably connected to a clamping frame 201. The side wall of the clamping frame 201 away from the center of the bottom cover 2 extends downward to form a clamping extension plate 202. The lower end of the clamping extension plate 202 is evenly distributed with a number of first clamping teeth 203 facing the center of the bottom cover 2. The edges of both ends of the bottom cover 2 are evenly distributed with a number of second clamping teeth 204 that are interleaved with the first clamping teeth 203. When the clamping frame 201 moves toward the center of the bottom cover 2, the first clamping teeth 203 will approach the second clamping teeth 204. The first clamping teeth 203 and the second clamping teeth 204 can clamp the wiping material. When the clamping frame 201 moves away from the center of the bottom cover 2, the first clamping teeth 203 will move away from the second clamping teeth 204, and the wiping material will be released.

[0061] A sliding plate 205 is symmetrically connected to the side wall of the clamping frame 201 near the center of the bottom cover 2. The sliding plate 205 is connected to a sliding block 206, and the sliding block 206 is provided with a sliding block ramp 207. The bottom cover 2 is provided with a guide protrusion 208 and a guide plate 209. The guide protrusion 208 is located on one side of the sliding plate 205 and is provided with a guide flange 210. The sliding plate 205 is locked under the guide flange 210, and the guide plate 209 is located on the other side of the sliding plate 205, so that the sliding plate 205 slides between the guide protrusion 208 and the guide plate 209. The guide protrusion 208 and the guide plate 209 guide the direction of the sliding plate 205 when sliding. The guide flange 210 limits the top surface of the sliding plate 205 to prevent the sliding plate 205 from being pushed up when sliding. The bottom cover 2 has a C-shaped abutment plate 211. A clamping bracket convex shaft 212 is located on the side wall of the clamping frame 201 near the center of the bottom cover 2. The clamping bracket convex shaft 212 is located between two sliding plates 205 and is connected to one end of a deformation spring 213. The other end of the deformation spring 213 abuts against the inner side of the abutment plate 211. A push plate 301 corresponding to the sliding block 206 is fixedly connected to the inner side of the top cover 3. The push plate 301 has a push plate ramp 302, which has the same inclination direction as the sliding block ramp 207. When the push plate moves downwards, the push plate ramp abuts against the sliding block ramp, causing the clamping frame to be compressed by an oblique force, thus moving the sliding block towards the center of the bottom cover. Specifically, in its natural state, due to the support of the deformation spring 213, the first clamping tooth 203 moves away from the second clamping tooth 204. When the top cover 3 is pressed down, the push plate 301 on the top cover 3 will move downward. Since the inclination direction of the push plate slope 302 and the sliding block slope 207 is the same and the lower end of the push plate slope 302 is above the sliding block slope 207, when the push plate 301 moves downward, the push plate slope 302 will resist the sliding block slope 207 and move downward, generating an oblique squeezing force on the sliding block 206. This oblique squeezing force will cause the sliding block 206 to move towards the center of the bottom cover 2, thereby driving the sliding plate 205 to move. At this time, the deformation spring 213 is compressed, thereby causing the first clamping tooth 203 to move towards the second clamping tooth 204. The first clamping tooth 203 and the second clamping tooth 204 are staggered to clamp the wiping material. Similarly, when the push plate 301 moves upward, the pressure of the push plate 301 on the sliding block 206 gradually decreases. The compression force of the deformation spring 213 will cause the sliding block 206 to move away from the center of the bottom cover 2, which in turn will drive the sliding plate 205 to move away from the center of the bottom cover 2, which will cause the first clamping tooth 203 to move away from the second clamping tooth 204. The first clamping tooth 203 and the second clamping tooth 204 separate, and the wiping material falls off.

[0062] The top cover 3 is connected to the spring-loaded frame 303. The spring-loaded frame 303 has spring-loaded connecting holes 304 at both ends, and a top cover protrusion 305 in the middle. The protrusion 305 has a through hole 306, which is connected to the spring-loaded connecting hole 304 by screws, thus achieving a fixed connection between the spring-loaded frame and the top cover 3. The spring-loaded frame 303 has a middle plate 307 in the middle, forming a symmetrically arranged first groove 308 and second groove 309 on the spring-loaded frame 303. A first spring-loaded block 310 is slidably connected in the first groove 308, and a second spring-loaded block 311 is slidably connected in the second groove 309. One end of the first rebound block 310 is provided with a first rebound block protrusion 312, and the side wall of the intermediate plate 307 located in the first groove 308 is provided with a first groove protrusion 313. A first spring 314 is connected between the first rebound block protrusion 312 and the first groove protrusion 313. The compression and extension of the first spring 314 realize the sliding of the first rebound block 310. One end of the second rebound block 311 is provided with a second rebound block protrusion 315, and the side wall of the intermediate plate 307 located in the second groove 309 is provided with a second groove protrusion 316. A second spring 317 is connected between the second rebound block protrusion 315 and the second groove protrusion 316. The compression and extension of the second spring 317 realize the sliding of the second rebound block 311. The lower part of the other end of the first rebound block 310 is provided with a first locking block 318. The lower edge of the first locking block 318 is provided with a first locking block ramp 319. The bottom cover 2 is provided with a first locking groove 214 corresponding to the first locking block 318. When the first locking block 318 is locked in the first locking groove 214, the upper edge of the first locking block 318 is locked in the top surface of the first locking groove 214. The setting of the first locking block ramp 319 makes it easier for the first locking block 318 to be locked in the first locking groove 214. The lower part of the other end of the second rebound block 311 is provided with a second locking block 320. The lower edge of the second locking block 320 is provided with a second locking block ramp 321. The bottom cover 2 is provided with a second locking groove 215 corresponding to the second locking block 320. When the second locking block 320 is locked in the second locking groove 215, the upper edge of the second locking block 320 is locked in the top surface of the second locking groove 215. The setting of the second locking block ramp 321 makes it easier for the second locking block 320 to be locked in the second locking groove 215.The top cover 3 is symmetrically provided with a first top cover through hole 322 and a second top cover through hole 323. The top surface of the first rebound block 310 is provided with a first rebound button 324, and the top surface of the second rebound block 311 is provided with a second rebound button 325. The first rebound button 324 passes through the first top cover through hole 322 and is movably connected inside the first top cover through hole 322. The second rebound button 325 passes through the second top cover through hole 323 and is movably connected inside the second top cover through hole 323. The first rebound button 324 can move in the direction closer to the center of the bottom cover 2 inside the first top cover through hole 322, and the second rebound button 325 can move in the direction closer to the center of the bottom cover 2 inside the second top cover through hole 323.

[0063] Specifically, when the top cover 3 is pressed down, the spring frame 303 will move downwards. In its natural state, the first locking block 318 is above the first locking groove 214, and the second locking block 320 is above the second locking groove 215. When the first spring block 310 and the second spring block 311 move downwards with the spring frame 303, the first locking block ramp 319 of the first locking block 318 will abut against the first locking groove 214 and move downwards, and the second locking block ramp 321 of the second locking block 320 will abut against the second locking groove 215 and move downwards. At this time, the first spring 314 and the second spring 317 are compressed respectively. When the upper edge of the first locking block 318 is engaged with the top surface of the first locking groove 214, and the upper edge of the second locking block 320 is engaged with the top surface of the second locking groove 215, the top cover 3 stops moving downwards. At the same time, the downward movement of the top cover 3 will cause the push plate 301 on the top cover 3 to move downward, the deformation spring 213 will be compressed, and the first clamping tooth 203 on the clamping frame 201 will move towards the direction of the second clamping tooth 204, thereby achieving the clamping of the wiping object. When the first rebound button 324 and the second rebound button 325 are simultaneously pressed, and the first rebound button 324 and the second rebound button 325 move towards each other towards the center of the bottom cover 2, the first rebound block 310 and the second rebound block 311 will move towards each other, thereby compressing the first spring 314 and the second spring 317 at the same time, thereby causing the first locking block 318 to disengage from the locking of the first locking groove 214 and the second locking block 320 to disengage from the locking of the second locking groove 215, causing the rebound frame to move upward, thereby driving the top cover 3 to move upward. Simultaneously, the upward movement of the top cover 3 causes the push plate 301 to move upward, gradually disengaging it from the sliding block 206. The elastic force of the deformation spring 213 causes the sliding plate 205 to move away from the center of the bottom cover 2, which in turn causes the first clamping tooth 203 to move away from the second clamping tooth 204, causing the wiping material to fall off. This eliminates the need for direct hand operation when installing and replacing the wiping material. To install the wiping material, simply press down on the top cover 3; to remove the wiping material, simply press the first return button 324 and the second return button 325. This is simple, convenient, time-saving, and labor-saving, and avoids contact between hands and dirt and germs on the wiping material, enhancing the user experience.

[0064] In another preferred embodiment, the clamping frame is slidably connected to the lower surface of the top cover, and the push plate is fixedly connected to the upper surface of the bottom cover. The push plate corresponds to the sliding block on the clamping frame, and the inclination direction of the push plate ramp 302 and the sliding block ramp 207 is the same. When the top cover is pressed down, the pressure of the top cover is transmitted to the clamping frame through force transmission. Through the interaction between the push plate ramp 302 and the sliding block ramp 207, the clamping frame is squeezed by the oblique force of the bottom cover, which in turn compresses the deformation spring and causes the clamping frame to move closer to the center of the top cover to clamp the wiping object.

[0065] Limiting plates 326 are provided at the four corners of the top cover 3. The bottom surface of the limiting plate 326 is provided with a limiting edge 327. The bottom cover 2 is provided with a limiting hole 216 corresponding to the limiting plate 326. When the first rebound button 324 and the second rebound button 325 are pressed, the top cover 3 will move upward. When the limiting plate 326 is engaged in the limiting hole 216, the top surface of the limiting edge 327 abuts against the bottom surface of the limiting hole 216, thereby limiting the upward movement of the top cover 3. The bottom surface of the bottom cover 2 is connected to the flat plate 4, which is made of soft rubber. The bottom surface of the flat plate 4 has several herringbone-shaped protrusions 401 evenly distributed, allowing the wiping material to better adhere to the wiping surface. The bottom cover 2 has several bottom cover holes 217 on both sides and a bottom cover groove 218 in its center. The flat plate 4 has flat plate protrusions 402 that are interference-fitted with the bottom cover holes 217. The center of the flat plate 4 has a hollow flat plate protrusion 403, which can be inserted into the bottom cover groove 218, achieving a fixed connection between the flat plate 4 and the bottom cover 2 and ensuring the stability of the connection. The top cover 3 is connected to the scraper 5 around its front edge. The scraper 5 is made of soft rubber and is formed by secondary injection molding, covering the top surface of the top cover 3 around its edge, ensuring the connection stability of the scraper 5. By setting scraper strips 5 around the perimeter, after the wiping material has wiped the surface, some water stains will usually remain on the surface. The wiping body 1 can be turned over and the scraper strips 5 can be used to scrape off the water stains on the surface. In addition, since the scraper strips 5 are set around the perimeter of the top cover 3, the scraper strips 5 can fit better at the corners of the wiping surface when in use, making wiping more convenient and time-saving.

[0066] The top cover 3 and the handheld part 6 are connected by a connecting assembly, which includes a first connecting member 601, a steering block 602, and a second connecting member 603. The first connecting member 601 is connected to the top cover 3, and the second connecting member 603 is connected to the handheld part 6. The first connecting member 601 and the second connecting member 603 are connected by the steering block 602. The top cover 3 has at least two first through holes 328 in the center of its front side. The first connecting member 601 is hollow and has a mounting post 604 at its bottom that matches the first through holes 328. The mounting post 604 can be inserted into the first through holes 328 and connected to the top cover 3 by bolts. The center of the first connecting member 601 is recessed inward to form a recessed part 605. The bottom of the recessed part 605 has a notch 606, and the side wall of the recessed part 605 has a mounting hole 607 that communicates with the notch 606. A support member 608 is inserted into the first connector 601. The bottom of the support member 608 mates with the recess 606, allowing the support member 608 to pass through the recess 606. The two sides of the support member 608 extend upward to form snap-fit ​​supports 609. The sidewalls of the snap-fit ​​supports 609 abut against the sidewalls of the mounting holes 607. The top of the snap-fit ​​supports 609 is provided with a support groove 610, which forms a second through hole 611 with the top of the mounting hole 607 on the same side.

[0067] The steering block 602 has a first pin 612 at both ends, which is integrally formed with the steering block 602. The first pin 612 is rotatably connected in the second through hole 611, realizing the front-to-back rotatable connection between the steering block 602 and the first connecting member 601. The steering block 602 also has a third through hole 613 in a direction perpendicular to the first pin 612. The end of the second connecting member 603 has a first snap-fit ​​plate 614 and a second snap-fit ​​plate 615. The steering block 602 can be snapped between the first snap-fit ​​plate 614 and the second snap-fit ​​plate 615. The first snap-fit ​​plate 614 has a fourth through hole 616, and the second snap-fit ​​plate 615 has a fifth through hole 617. The rotating shaft 618 passes through the fourth through hole 616, the third through hole 613, and the fifth through hole 617 in sequence, so that the steering block 602 is rotatably connected to the second connecting member 603. The top of the steering block 602 is arc-shaped. The second connecting member 603 can rotate around the top of the steering block 602 with the pivot shaft 618 as the center, thereby realizing the left and right rotational connection between the second connecting member 603 and the steering block 602. One end of the top of the steering block 602 is provided with a notch 619. The second connecting member 603 is provided with a receiving block 620. One end of the receiving block 620 is connected to a retaining spring, and the retaining spring abuts against the second connecting member 603. The other end of the receiving block 620 abuts against the notch 619, which allows the second connecting member 603 to be folded to a position parallel to the wiping body 1 and maintained in this state, enhancing the convenience of use. The top surface of the support member 608 is provided with a support protrusion 621 parallel to the top cover 3 in the middle. The bottom of the steering block 602 is provided with symmetrical support plates 622 on both sides. When the second connector 603 rotates relative to the first connector 601, and the support plate 622 abuts against the side wall adjacent to the support protrusion, the handheld part 6 and the wiping body 1 can be fixed in place.

[0068] The handheld part 6 includes a receiving rod 7, which engages with a second connecting member 603. The second connecting member 603 has a second connecting member through hole 701 on its side wall. The lower part of the receiving rod 7 has a mounting groove 702, which is connected to a locking block 704 via a spring piece 703. The locking block 704 matches the second connecting member through hole 701 and engages with it, thus connecting the receiving rod 7 to the second connecting member 603, and consequently connecting the connecting assembly to the handheld part 6. Assembly can be completed without tools, significantly improving operational efficiency. The handheld part 6 also includes a first extension rod 8, a second extension rod 9, and a sleeve 10. One end of the first extension rod 8 is inserted into the receiving rod 7, and the other end is inserted into one end of the sleeve 10. One end of the second extension rod 9 is inserted into the other end of the sleeve 10, enabling stepless length adjustment of the handheld part 6 to accommodate operators of different heights or usage scenarios.

[0069] The handheld part 6 also includes a gripping assembly 11, which is used to grip the wiped-off dirt, avoiding the need for hand picking and making it more hygienic. The gripping assembly 11 includes a gripping link 1101 and a gripper 1102. The gripping link 1101 and the gripper 1102 are threadedly connected. A second extension rod 9 is inserted into the gripping link 1101, and one end of the gripper 1102 extends into the second extension rod 9, thus connecting the second extension rod 9 to the gripping assembly 11. The gripper 1102 includes an integrally formed gripper connecting part 1103 and two clamps 1104, making the overall structure more stable. The two clamps 1104 can extend into the second extension rod 9, so that when the gripping assembly 11 is not used to grip dirt, it can be housed in the second extension rod 9 for easier handling. A third spring 1105 is connected to the middle of the inner side of the two clamps 1104 to ensure the elasticity between the two clamps 1104. Because the two clamps 1104 are inserted into the second extension rod 9, the internal space of the second extension rod 9 is relatively small, so the two clamps 1104 are always in a clamped state. After a period of use, the elasticity between the two clamps 1104 will fail, so the two clamps 1104 cannot open, and the user needs to deliberately open the two clamps 1104 to achieve the gripping of dirt.

[0070] The end of the gripper connecting part 1103 away from the gripper has a connecting groove 1106. A cover 1107 is engaged within the connecting groove 1106, sealing the connecting groove 1106 and preventing dust and other contaminants from falling into it. The bottom of the cover 1107 has a cover groove 1108, within which a hanging rope 1109 is connected. Both ends of the hanging rope 1109 can be inserted into the cover groove 1108 simultaneously, and the hanging rope 1109 is bendable. The hanging rope 1109 makes it easier to hang the wiper on an exterior wall, reducing space usage and making it more convenient to retrieve. The hanging rope 1109 has hanging rope protrusions 1110 at both ends, and a hanging rope hole 1111 in the middle of the hanging rope protrusions 1110. The sealing groove 1108 has sealing protrusions 1112 on both sides, which can be inserted into the hanging rope hole 1111 to connect the hanging rope 1109 and the sealing cover 1107. In use, the hanging rope 1109 is folded in half, and both folded ends are simultaneously inserted into the sealing groove 1108 on the sealing cover 1107, so that the two hanging rope holes 1111 on the hanging rope protrusions 1110 are fitted onto the corresponding sealing protrusions 1112. This simple operation ensures a secure connection between the hanging rope 1109 and the sealing cover 1107, preventing the hanging rope 1109 from easily coming loose.

[0071] In this embodiment, the multifunctional wiper is used by placing the object to be wiped under the flat plate 4 and pressing down on the top cover 3. The spring frame 303 will then move downwards. The first locking block 318 on the spring frame 303 will abut against the first locking groove 214 and move downwards, while the second locking block 320 will abut against the second locking groove 215 and move downwards. At the same time, the first spring 314 and the second spring 317 are compressed. When the first locking block 318 is engaged in the first locking groove 214 and the second locking block 320 is engaged in the second locking groove 215, the top cover 3 stops moving downwards. Simultaneously, the push plate 301 on the top cover 3 moves downwards, compressing the deformation spring. This causes the first clamping tooth 203 on the clamping frame 201 to move towards the second clamping tooth 204, thereby clamping the object to be wiped. After wiping the surface, simultaneously press the first rebound button 324 and the second rebound button 325 towards each other, moving them closer to the center of the bottom cover 2. This causes the first locking block 318 to disengage from the first locking groove 214 and the second locking block 320 to disengage from the second locking groove 215, causing the rebound frame to move upward. This, in turn, moves the top cover 3 upward. Simultaneously, the upward movement of the top cover 3 causes the push plate 301 to move upward. The compression force of the deformation spring causes the sliding plate 205 to move away from the center of the bottom cover 2, which in turn causes the first clamping tooth 203 on the clamping frame 201 to move away from the second clamping tooth 204, causing the wiped item to fall off. If there are water stains on the wiped surface, flip the wiper over and place the scraper 5 against the wiped surface to scrape off the water stains. When there is dirt on the wiped surface, the gripper 1102 can be unscrewed from the gripping link 1101 to grip the dirt. After use, the lanyard 1109 can be hung on an exterior wall to store the items being wiped.

[0072] Second Embodiment

[0073] This embodiment provides a multifunctional wiper, such as Figures 14-15 As shown, the device includes a wiping body 1 and a handheld part 6. The wiping body 1 includes a top cover 3 and a bottom cover 2 connected by a gap. The outer walls of the front and rear end faces of the bottom cover are provided with several locking protrusions 219, which are evenly arranged and aligned in a straight line. The front and rear end faces of the top cover are provided with inner sidewalls 329. When the top cover is pressed down, because the outer surface of the locking protrusions is arc-shaped, the locking protrusions 219 easily engage with the inner sidewall 329 on the same side of the top cover due to interference fit. When the wiping body is swung downwards, the bottom cover moves downwards due to centrifugal force, causing the locking protrusions 219 to disengage from the inner sidewall 329. It should be noted that the other components and connections in this embodiment are the same as in the first embodiment, and will not be described again here.

[0074] In this embodiment, the multifunctional wiper is used by placing the object to be wiped under the flat plate 4 and pressing down on the top cover 3. When the snap-fit ​​protrusion 219 on the bottom cover snaps into the inner wall 329 of the top cover on the same side, the top cover 3 stops moving downward. At the same time, the push plate 301 on the top cover 3 moves downward, compressing the deformation spring and causing the first clamping tooth 203 on the clamping frame 201 to move towards the second clamping tooth 204, thereby clamping the object to be wiped. After wiping the surface, when the wiping body is swung downward, the bottom cover is subjected to centrifugal force and its own weight, and overcomes the friction with the top cover, causing the bottom cover to move downward. This causes the snap-fit ​​protrusion 219 to disengage from the inner wall 329 of the top cover. At the same time, the compression force of the deformation spring causes the sliding plate 205 to move away from the center of the bottom cover 2, thereby causing the first clamping tooth 203 on the clamping frame 201 to move away from the second clamping tooth 204, and the object to be wiped falls off.

[0075] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
