Description

Technical Field

[0001] This utility model relates to the field of flat mop technology, and in particular to a hands-free flat mop that is easy to add cleaning solution to. Background Technology

[0002] In daily cleaning, hands-free flat mops are widely popular due to their simple structure and ease of use. Existing hands-free mops generally consist of a flat mop and a wringer assembly surrounding it. The flat mop includes a mop head and a mop handle. The cleaning material is movably connected to the back of the mop head, while the mop handle is rotatably connected to the front of the mop head. Users clean the floor by holding the mop handle. The wringer assembly includes a connecting sleeve that is fitted onto the mop handle. The wringer assembly has a spout with an opening. The connecting sleeve moves up and down on the mop handle, allowing the mop head to move within the opening. A squeezing mechanism within the opening cleans and dehydrates the cleaning material.

[0003] However, existing hands-free flat mops still have some shortcomings. During the wringing and cleaning process, existing hands-free flat mops lack a container for holding cleaning solution. Users need to apply the cleaning solution directly to the surface or pour it into the mop's cleaning bucket, which inevitably leads to cumbersome operation, poor cleaning results, and reduced cleaning efficiency. It may also cause users to frequently change the surface they are wiping, increasing cleaning costs and workload, and negatively impacting the user experience. Utility Model Content

[0033] The present invention achieves the following beneficial technical effects compared to the prior art:

[0034] This utility model provides a hands-free flat mop that facilitates the addition of cleaning liquid. When the mop plate 3 moves up and down within the spout 201, the wiping material on the mop plate 3 presses against the head 218 of the squeezing member 217, causing the cylindrical part of the squeezing member 217 to move towards the liquid filling chamber 203. This, in turn, causes the sealing ring 221 and the connecting bracket 206 to move towards the liquid filling chamber 203, compressing the compression spring 216. At this time, the seal of the seepage hole 204 is released, and the cleaning liquid flows out through the groove 222 of the cylindrical part onto the wiping material. The user can clean the wiping material on the mop plate 3 while the cleaning liquid adheres to it. After cleaning the wiping material, i.e., when the mop plate 3 leaves the spout 201, the elasticity of the compression spring 216 causes the connecting bracket 206 and the sealing ring 221 to return to their original positions, and the squeezing member 217 also returns to its original position. The sealing ring 221 seals the seepage hole 204, and the cleaning liquid no longer flows out. The hands-free flat mop in this embodiment cleans the objects being wiped on the mop board 3 while also applying cleaning liquid to them. This avoids the cleaning liquid from spilling onto the floor or other non-target areas, preventing unnecessary cleaning burden and eliminating the need for manual refilling. It achieves convenient and automatic addition of cleaning liquid, saving time and effort, reducing waste of cleaning liquid, improving cleaning efficiency, ensuring cleaning effect, and enhancing user experience.

[0049] This embodiment provides a hands-free flat mop that is easy to add cleaning solution, such as... Figures 1-9 As shown, the system includes a mop handle 1 connected to a mop board 3. A wiping agent is mounted on the mop board 3 and attached to it via hooks 301 at both ends for cleaning the floor. The mop handle 1 is slidably connected to a wringer assembly 2, which includes a spout 201 and a wringer plate 202. The wringer plate 202 has a liquid filling chamber 203 for holding cleaning fluid, such as 84 disinfectant or floor cleaner. The liquid filling chamber 203 has several seepage holes 204 on its side wall near the spout 201. In this embodiment, there are two seepage holes 204, and they are symmetrically arranged.

[0050] The filling chamber 203 has two symmetrically arranged C-shaped fixing plates 205. A connecting frame 206 is movably connected to the fixing plates 205. The connecting frame 206 matches the fixing plates 205, allowing the connecting frame 206 to move along the width direction of the two fixing plates 205. The C-shaped fixing plates 205 guide the movement of the connecting frame 206. The filling chamber 203 has a filling chamber opening 207 at the top. A cover plate 208 is engaged with the filling chamber opening 207 and can close the filling chamber opening 207. The cover plate 208 is connected to a sealing plate 209. The cover plate 208 has a cover plate mounting hole 210 and a filling hole 211. The sealing plate 209 has a sealing plate protrusion 212 and a sealing plate groove 213. The sealing plate protrusion 212 is inserted into the cover plate mounting hole 210, and the sealing plate groove 213 is inserted into the filling hole 211. By connecting the sealing plate protrusion 213 to the filling hole 211 and the sealing plate protrusion 212 to the cover plate mounting hole 210, a tight connection is achieved between the cover plate 208 and the sealing plate 209, effectively reducing the risk of liquid leakage from the filling chamber opening 207 and improving the sealing performance of the filling chamber 203. When the user needs to add cleaning fluid to the filling chamber 203, simply pull the sealing plate protrusion 213 out of the filling hole 211 to perform the filling operation. After the filling is completed, reinsert the sealing plate protrusion 213 into the filling hole 211 to seal the filling chamber 203. The operation is simple and convenient. The connecting frame 206 has a first protruding shaft 214 on the side near the seepage hole 204 and a second protruding shaft 215 on the side away from the seepage hole 204. The connecting frame 206 is connected to a compression spring 216. One end of the compression spring 216 is sleeved on the second protruding shaft 215, and the other end abuts against the side wall of the cover plate 208.

[0051] The connecting frame 206 is connected to the extrusion member 217. Specifically, the extrusion member 217 includes a head 218 and a cylindrical part 219. The head 218 is located outside the liquid filling tank 203. The head 218 of the extrusion member 217 is mushroom-shaped, which makes the scraping motion of the mop blade 3 after it abuts against the extrusion member 217 smoother. The cylindrical part 219 passes through the seepage hole 204. The center of the cylindrical part 219 has a cylindrical through hole 220. The first protruding shaft 214 is inserted into the cylindrical through hole 220, realizing the connection between the connecting frame 206 and the extrusion member 217. A sealing ring 221 is sleeved on the end of the cylindrical part 219. One side of the sealing ring 221 abuts against the connecting frame 206, and the other side abuts against the side wall of the liquid filling tank 203 near the spout 201. Under normal conditions, the sealing ring 221 seals the seepage hole 204, so that the cleaning liquid will not flow out from the seepage hole 204. A plurality of cylindrical grooves 222 are evenly distributed circumferentially along the axial direction of the cylindrical part 219 on the side wall of the cylindrical part 219. When the head 218 of the extruder 217 is subjected to external pressure, the cylindrical part 219 of the extruder 217 moves toward the liquid filling chamber 203, the compression spring 216 is compressed, and the movement of the cylindrical part 219 will drive the sealing ring 221 to move, so that the leakage hole 204 is released from the seal, and a gap is generated between the cylindrical part 219 and the leakage hole 204, and the cleaning liquid will flow out through the cylindrical grooves 222.

[0052] Specifically, when the mop blade 3 moves up and down within the spout 201, the wiping material on the mop blade 3 presses against the head 218 of the extruder 217, causing the cylindrical portion of the extruder 217 to move towards the liquid filling chamber 203. This, in turn, causes the sealing ring 221 and the connecting bracket 206 to move towards the liquid filling chamber 203, compressing the compression spring 216. At this point, the seal of the seepage hole 204 is released, and the cleaning fluid flows out through the cylindrical groove 222 onto the wiping material. The user can clean the wiping material on the mop blade 3 while the cleaning fluid adheres to it. After cleaning the wiping material, i.e., when the mop blade 3 leaves the spout 201, the elasticity of the compression spring 216 causes the connecting bracket 206 and the sealing ring 221 to return to their original positions, and the extruder 217 also returns to its original position. The sealing ring 221 seals the seepage hole 204, and the cleaning fluid no longer flows out. The hands-free flat mop in this embodiment cleans the objects being wiped on the mop board 3 while also applying cleaning liquid to them. This avoids the cleaning liquid from spilling onto the floor or other non-target areas, preventing unnecessary cleaning burden and eliminating the need for manual refilling. It achieves convenient and automatic addition of cleaning liquid, saving time and effort, reducing waste of cleaning liquid, improving cleaning efficiency, ensuring cleaning effect, and enhancing user experience.

[0053] The spout 201 also includes a wringer 223. A through-hole 224 is formed between the wringer 202 and the wringer 223. When the mop board 3 moves within the through-hole 224, the wiping material will come into contact with and squeeze the head of the squeezing member, causing the cleaning liquid to flow onto the wiping material for cleaning. When the mop board moves outside the through-hole, the wiping material will not come into contact with the head of the squeezing member, nor will it squeeze the squeezing member anymore, so that the cleaning liquid will not leak out, further avoiding waste of cleaning liquid. The dewatering plate 202 has a first snap-fit ​​groove 225 and a first snap-fit ​​plate 226 at both ends. The dewatering frame 223 has a second snap-fit ​​groove 227 and a second snap-fit ​​plate 228. The first snap-fit ​​plate 226 can snap into the second snap-fit ​​groove 227, and the second snap-fit ​​plate 228 can snap into the first snap-fit ​​groove 225, so that the dewatering plate 202 and the dewatering frame 223 are snapped together. Moreover, the dewatering plate 202 and the dewatering frame 223 will not move in the front, back, left and right directions, thus ensuring the stability of the structure. After the dewatering plate 202 and the dewatering frame 223 are engaged, they are connected to the snap-fit ​​member 229. The snap-fit ​​member 229 covers the ends of the dewatering plate 202 and the dewatering frame 223 after they are connected. The upper end face of the dewatering plate 202 is provided with a first slot 230 or a first protrusion 231. The snap-fit ​​member 229 is provided with a first protrusion 231 or a first slot 230 that engages with the first slot 230 or the first protrusion 231. The lower end face of the dewatering frame 223 is provided with a second slot 232 or a second protrusion 233. The snap-fit ​​member 229 is provided with a second protrusion 233 or a second slot 232 that engages with the second slot 232 or the second protrusion 233. When the dewatering plate 202 and the dewatering frame 223 are engaged, one end of the snap-fit ​​member 229 can be snapped onto the dewatering plate 202, and the other end of the snap-fit ​​member 229 can be snapped onto the dewatering frame 223. In this embodiment, the upper end face of the dewatering plate 202 is provided with a first slot 230, the upper end of the snap-fit ​​member 229 is provided with a first protrusion 231, the lower end face of the dewatering frame 223 is provided with a second slot 232, and the lower end of the snap-fit ​​member 229 is provided with a second protrusion 233. During installation, the dewatering plate 202 and the dewatering frame 223 are first snapped together as one unit, then the snap-fit ​​member 229 is wrapped around the outside of the dewatering plate 202 and the dewatering frame 223, and the first protrusion 231 is snapped into the first slot 230, and the second protrusion 233 is snapped into the second slot 232 to achieve the connection of the snap-fit ​​members 229 on both sides, thus ensuring the connection stability of the device.If the wringer plate 202 and the wringer frame 223 are connected by direct insertion and snap-fit, the wringer plate 202 and the wringer frame 223 are prone to separation during the cleaning or squeezing process of the wringer assembly 2 on the flat mop board 3. In this embodiment, however, the snap-fit ​​component 229 covers and snaps onto both ends of the wringer plate 202 and the wringer frame 223 after they are integrated. During the cleaning process of the wringer assembly 2, the pressure exerted on the mop board 3 is directly applied to the snap-fit ​​component 229. This pressure is then transmitted through the two ends of the snap-fit ​​component 229 to the connection points of the first slot 230 and the first protrusion 231, and the second slot 232 and the second protrusion 233, making the mop less prone to damage and ensuring its lifespan. Furthermore, embedding the snap-fit ​​component 229 into the wringer plate 202 and the wringer frame 223 enhances the aesthetics.

[0054] A scraper 234 is rotatably connected inside the wringer 202, and a limiting plate 235 is provided between the scraper 234 and the liquid filling tank 203. Rollers 236 are symmetrically arranged on the wringer frame 223, and the rollers 236 can roll along the length of the mop board 3. Thus, when the mop board 3 moves up and down through the opening 224, the scraper 234 scrapes and cleans the object being wiped, and the liquid filling tank 203 applies cleaning agent to the surface of the object and squeezes it to remove water. The rollers 236 support the mop board 3, allowing it to move smoothly up and down within the opening 224. In addition, by providing a limiting plate 235 on the wringer 202 and setting the limiting plate 235 between the scraper 234 and the liquid filling chamber 203, when the scraper 234 is perpendicular to the mop board 3, the limiting plate 235 will hold the scraper 234 in place. When the mop board 3 passes through the opening 224, it will drive the scraper 234 to rotate backward and then the scraper 234 will press against the limiting plate 235. At this time, the width of the opening 224 is the smallest, the scraping force on the wiping object is the greatest, and the dirt on the wiping object will be cleaned more conveniently.

[0055] The wringer assembly 2 also includes a connecting sleeve 237 and a connecting cylinder 238 connected together. The connecting sleeve 237 and the connecting cylinder 238 are fitted around the outer periphery of the mop handle 1, and the connecting sleeve 237 is connected to the wringer frame 223. Specifically, the wringer frame 223 is provided with a first connecting part 239, and the end of the connecting cylinder 238 near the mop plate 3 is provided with a second connecting part 240. The shapes of the first connecting part 239 and the second connecting part 240 are adapted to the connecting sleeve 237. One end of the connecting sleeve 237 is inserted and fixed in the first connecting part 239, and the other end of the connecting sleeve 237 is inserted and fixed in the second connecting part 240, so that the connecting sleeve 237 is assembled and connected to the spout 201 and the connecting cylinder 238 through the first connecting part 239 and the second connecting part 240 to form the wringer assembly 2, which is easy to install. The connecting sleeve 238 drives the connecting sleeve 237, causing the entire wringer assembly 2 to slide on the mop handle 1. This assembly method allows the wringer assembly 2 to have wider versatility; that is, by simply changing the length of the connecting sleeve 237, the wringer assembly 2 can be adapted to mop boards 3 of different lengths. The connecting sleeve 237 has a C-shaped cross-section with an opening 241. Limiting edges 242 are provided on both sides of the opening 241 to prevent gaps between the connecting sleeve 237 and the mop handle 1. Limiting strips 243 are provided on the limiting edges 242. Bolt protrusions (not shown) are provided on the mop handle 1. The bolt protrusions and the limiting strips 243 mutually limit each other, preventing the wringer assembly 2 from rotating. The limiting line 242 has a first hole 244 at both ends along the length of the connecting sleeve 237, and a second hole 245 on both the first connecting part 239 and the second connecting part 240. The first holes 244 and the second holes 245 are compatible. After inserting both ends of the connecting sleeve 237 into the first connecting part 239 of the wringer 223 and the second connecting part 240 of the connecting cylinder 238 respectively, screws are tightened at the first holes 244 and the second holes 245 to complete the assembly of the wringer sleeve assembly 2. The installation is convenient.

[0056] The mop plate 3 is connected to the mop handle 1 via a connecting assembly 4. The connecting assembly 4 includes a first connecting member 401 and a second connecting member 402. The first connecting member 401 is connected to the second connecting member 402 via a steering block 403. The first connecting member 401 is used to connect to the mop plate 3, and the second connecting member 402 is used to connect to the mop handle 1. The mop plate 3 has at least two mop plate through holes 404 in the middle of its side surface opposite to the wiping object. The bottom of the first connecting member 401 has a receiving post 405, which can be inserted into the mop plate through holes 404 and connected by bolts to realize the connection between the connecting assembly 4 and the mop plate 3. The first connecting member 401 is hollow, and its middle part is recessed inward, so that the first connecting member 401 includes a communicating notch 406 and a first mounting hole 407. The first connecting member 401 is internally connected to the support member 408, which is made of plastic. The base plate 414 of the support member 408 is adapted to the recess 406, allowing the support member 408 to pass through the recess 406. The two sides of the support member 408 extend upward to form symmetrical support blocks 409, which are accommodated in the first mounting hole 407 on the same side. The top surface of the support block 409 is provided with a support groove 410, which forms a support through hole 411 with the top surface of the first mounting hole 407. The two sides of the support member 408 are also symmetrically provided with support member locking platforms 412. The first mounting hole 407 is provided with a receiving groove 413, and the support member locking platforms 412 abut against the receiving groove 413, preventing the support member 408 from shaking in the first connecting member 401 and ensuring the stability of the device.

[0057] The upper surface of the base plate 414 of the support member 408 is provided with a support member protrusion 415, which is parallel to the mop plate 3. Symmetrical protrusions 416 are provided on both sides of the bottom of the steering block 403. The two protrusions 416 are the same size and on the same plane. When the second connecting member 402 rotates relative to the first connecting member 401, the support member protrusion 415 can abut against the protrusions 416 on the same side, thus achieving the fixation and reliable connection between the mop handle 1 and the mop plate 3. Steering block 403 has steering block convex shafts 417 on both sides. The steering block convex shafts 417 are integrally formed with steering block 403. The steering block convex shafts 417 are rotatably connected in the support through hole 411 to realize the front and rear rotational connection between steering block 403 and first connecting member 401. Steering block 403 has a steering block through hole 418 in the direction perpendicular to the steering block convex shaft 417. The second connecting member 402 has a first support plate 419 and a second support plate 420 at one end near steering block 403. Steering block 403 can be engaged between the first support plate 419 and the second support plate 420. The first support plate 419 has a first support plate through hole 421, and the second support plate 420 has a second support plate through hole 422. The rotating shaft 423 passes through the first support plate through hole 421, the steering block through hole 418 and the second support plate through hole 422 in sequence, so that steering block 403 is rotatably connected to the second connecting member 402. The top of the steering block 403 is arc-shaped, allowing the second connector 402 to rotate around the pivot 423 along the top of the steering block 403, thus achieving a rotatable connection between the second connector 402 and the steering block 403. One end of the top of the steering block 403 has a notch 424, and the second connector 402 has a blocking block 425. One end of the blocking block 425 has a blocking block convex shaft, and a spring (not shown) is connected to the blocking block convex shaft. The spring abuts against the inside of the second connector 402, and the other end of the blocking block 425 abuts against the notch 424. This allows the second connector 402 to be folded to a position parallel to the mop board 3 and maintained in this state, improving ease of use.

[0058] The second connector 402 has a plug-in portion 426 at one end near the mop handle 3. A spring plate 427 is located in the middle of the plug-in portion 426, and strip-shaped through holes 428 are provided on both sides of the spring plate 427 to facilitate deformation during the snap-fit ​​process. A snap-fit ​​block 429 is located in the middle of the spring plate 427, and a snap-fit ​​hole 430 is located at one end of the mop handle 1 near the second connector 402. The snap-fit ​​block 429 can snap into the snap-fit ​​hole 430, connecting the second connector 402 to the mop handle 1, thus achieving the connection between the connecting component 4 and the mop handle 1.

[0059] The connecting tube 238 is provided with a locking part 431. By providing the locking part 431, the state of the locking part 431 can be switched more conveniently when the wringer assembly 2 moves up and down, thereby switching the state of the wringer. When the locking part 431 is open, the swiping part 201 can slide relative to the mop handle 1, so that the wiping material on the mop plate 3 squeezes the head 218 of the squeezing member 217, causing the cleaning liquid to flow from the liquid filling tank 203 onto the wiping material. At the same time, the scraper 234 squeezes the wiping material in the through hole 224 and performs cleaning and scraping. When the locking part 431 is locked, the swiping part 201 is fixed on the mop handle 1 for easy cleaning of the floor. Specifically, the locking part 431 includes a toggle plate 432 and a clamping plate 433 connected together. The toggle plate 432 is provided with a "locking mark" and a "releasing mark". One end of the clamping plate 433 is inclinedly connected to the middle of the toggle plate 432, so that the two form an angle. A protruding post 434 is provided at the connection between the clamping plate 433 and the toggle plate 432. The connecting cylinder 238 is provided with a locking hole 435. Connecting seats 436 extend from both sides of the locking hole 435. The connecting seats 436 are provided with hinge holes 437. The protruding post 434 can be rotatably connected in the hinge hole 437, so that the clamping plate 433 can rotate in the locking hole 435. When in use, turn the lever plate 432 to the "Release" side. The movement of the lever plate 432 will cause the locking plate 433 to retract into the locking hole 435. At this time, the locking part 431 is in the open state. Turn the lever plate 432 to the "Lock" side and cause the locking plate 433 to move into the connecting cylinder 238 and protrude from the inner side wall of the connecting cylinder 238. At this time, the locking plate 433 is close to the mop handle 1 and squeezes the mop handle 1 against the side wall of the connecting cylinder 238. At this time, the mop handle 1 and the connecting cylinder 238 will not have relative displacement, thus locking the locking part 431 to the mop handle 1.

[0060] The mop board 3 is connected to the scraper 5 on both sides. If there is dust, garbage, or water stains on the floor, the scraper 5 can be used to sweep first, and then the wiping agent can be used for cleaning, which enhances the cleaning effect. Both sides of the mop board 3 are provided with mop board grooves, and the scraper 5 is provided with scraper protrusions. The scraper protrusions can be engaged with the mop board grooves to realize the connection between the scraper 5 and the mop board 3.

[0061] The present invention provides a hands-free flat mop that facilitates the addition of cleaning solution. In practical application, the wringer assembly 2 is fitted onto the mop handle 1. The actuating plate 432 is moved to rotate the locking plate 433 into the locking hole 435. At this time, there is a gap between the mop handle 1 and the connecting cylinder 238. Holding the connecting cylinder 238 causes the wringer assembly 2 to move up and down along the mop handle 1, and the mop plate 3 moves within the opening 224. The wiping material on the mop plate 3 squeezes the head 218 of the squeezing member 217, causing the cleaning solution to be added. The liquid flows out of the tank 203 onto the object to be wiped, while the scraper 234 squeezes the object in the opening 224 and cleans it. After cleaning the object, the actuating plate 432 is rotated, causing the clamping plate 433 to rotate into the inside of the connecting cylinder 238 and squeeze the inner wall of the connecting cylinder 238, thus eliminating the gap between the mop handle 1 and the connecting cylinder 238 and preventing relative movement between the mop handle 1 and the connecting cylinder 238. This fixes the wringer assembly 2 onto the mop handle 1, allowing the user to easily clean the floor by holding the flat mop.
