Description

Technical Field

[0001] The present invention relates to the technical field of cleaning tools, and particularly to a cleaning liquid adding device for cleaning tools, a mop bucket, and a hands-free flat mop. Background Art

[0002] In daily household cleaning, a mop is a commonly used cleaning tool with a very high usage frequency. To improve the cleaning effect, people usually add cleaning liquid to the mop head during the cleaning process. However, in actual operation, there are many inconveniences in the traditional cleaning liquid adding method. The traditional way of adding cleaning liquid is that the user needs to pour the cleaning liquid from the cleaning liquid container into a separate container (such as a small bowl or a bucket) in advance, and then manually smear or spray the cleaning liquid in the container evenly on the mop head. This process is not only cumbersome, increasing the steps and time costs of the cleaning work, but also likely to cause waste of the cleaning liquid. The excess cleaning liquid may spill on the ground or other non-target areas, causing unnecessary cleaning burden. Even when using a flat mop with a mop bucket, the user adds a certain amount of cleaning liquid to the mop bucket in advance. However, during the cleaning process, as the mop head is repeatedly washed and squeezed, the cleaning liquid in the bucket will gradually decrease. The user needs to frequently check the remaining amount of the cleaning liquid and add it again when necessary, which also affects the cleaning efficiency and thus the cleaning effect. Summary of the Invention

The user can make the cleaning liquid adhere to the wiping material while cleaning the wiping material on the mop head up and down. After cleaning the wiping material, when the mop head is about to be pulled out, the elastic force of the deformation spring will cause the connecting frame and the sealing ring to return to their original positions, the squeezing member will also return to its original position, the sealing ring will seal the liquid seepage hole, and the cleaning liquid will no longer flow out. The cleaning liquid adding device in this embodiment attaches the cleaning agent to the wiping material while cleaning the wiping material on the mop head, avoiding the situation that the cleaning liquid may spill on the ground or other non-target areas, causing unnecessary cleaning burden, avoiding manual addition again, achieving convenient and automatic addition of cleaning liquid, saving time and effort, reducing waste of cleaning liquid, improving cleaning efficiency, ensuring cleaning effect, and enhancing the user experience.

[0032] 2. The mop bucket provided by the present invention is also provided with a rebound assembly on the bucket cover, preferably with rebound assemblies on both sides of the clamping plate. The rebound assembly can move up and down on the lower side of the bucket cover; when the clamping protrusion is clamped on the lower edge of the opening of the bucket body, the rebound assembly is compressed and the lower end of the rebound assembly presses against the upper edge of the opening of the bucket body. When the clamping protrusion is disengaged from the lower edge of the opening of the bucket body, the rebound assembly is released and then pushes the bucket cover to bounce up from the bucket body. At the same time when the clamping protrusion disengages, the rebound assembly restores its deformation and pushes the bucket cover away from the bucket body to overcome the adhesion force between the bucket cover and the bucket body. In this way, after rotating the clamping plate to disengage the clamping protrusion from the lower edge, the bucket cover can be very conveniently and quickly removed from the bucket body.

[0033] 3. In the specific application process of the hands-free flat mop provided by the present invention, the water squeezing and smoothing sleeve assembly is sleeved on the mop rod. The locking part is rotated to make the locking part in a loose state. At this time, there is a gap between the mop rod and the connecting cylinder. Hold the connecting cylinder and move the water squeezing and smoothing sleeve assembly up and down along the mop rod, and the mop plate moves in the through hole. The wiping material on the mop plate squeezes the head of the squeezing member, so that the cleaning liquid flows out from the liquid adding bin onto the wiping material while the scraper squeezes the wiping material in the through hole and conducts cleaning and scraping; when the cleaning of the wiping material is completed, the locking part is rotated to make the locking part in a locked state, so that the mop rod and the connecting cylinder cannot move relative to each other, and then the water squeezing and smoothing sleeve assembly is fixed on the mop rod. The user can conveniently clean the ground by holding the flat mop. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0051] First embodiment

[0052] This embodiment provides a cleaning - liquid adding device for a cleaning tool, as Figures 1 - 3As shown in the figure, it includes a liquid adding bin 1. The liquid adding bin 1 is arranged on the cleaning tool and is adapted to the cleaning tool. The liquid adding bin 1 is used to contain cleaning liquid, and the cleaning liquid can be 84 disinfectant or floor cleaning liquid, etc. A number of liquid seepage holes 101 are provided on the side wall of the liquid adding bin 1. In this embodiment, the number of the liquid seepage holes 101 is two and the two liquid seepage holes 101 are symmetrically arranged. A connecting frame 102 is arranged in the liquid adding bin 1. A first protruding shaft 103 is provided on one side of the connecting frame 102 close to the liquid seepage hole 101, and a second protruding shaft 104 is provided on the other side of the connecting frame 102 away from the liquid seepage hole 101. A deformation spring 105 is arranged in the liquid adding bin 1. One end of the deformation spring 105 is sleeved on the second protruding shaft 104, and the other end is fixedly connected in the liquid adding bin 1. The connecting frame 102 is connected to the pressing member 106. Specifically, the pressing member 106 includes a head 107 and a cylindrical portion 108. The head 107 is located outside the liquid adding bin 1. The head 107 of the pressing member 106 is mushroom-shaped, so that the up and down movement after the mop head abuts against the pressing member 106 is smoother. The cylindrical portion 108 passes through the liquid seepage hole 101. A cylindrical portion through hole 109 is provided in the center of the cylindrical portion 108. The first protruding shaft 103 is inserted into the cylindrical portion through hole 109, realizing the connection between the connecting frame 102 and the pressing member 106. A sealing ring 110 is sleeved on the end of the cylindrical portion 108. One side of the sealing ring 110 abuts against the connecting frame 102, and the other side abuts against the side wall of the liquid adding bin 1. In the natural state, the sealing ring 110 seals the liquid seepage hole 101, so that the cleaning liquid will not flow out of the liquid seepage hole 101. A number of cylindrical portion grooves 111 are evenly circumferentially arranged on the side wall of the cylindrical portion 108 along the axial direction of the cylindrical portion 108. When the head 107 of the pressing member 106 is externally pressed, the cylindrical portion 108 of the pressing member 106 moves towards the liquid adding bin 1, the deformation spring 105 is compressed, and the movement of the cylindrical portion 108 will drive the movement of the sealing ring 110, so that the liquid seepage hole 101 is unsealed, a gap is generated between the cylindrical portion 108 and the liquid seepage hole 101, and the cleaning liquid will flow out through the cylindrical portion grooves 111.

[0053] Specifically, when the mop head moves up and down for cleaning, the wiping material on the mop head will squeeze the head 107 of the squeezing member 106, driving the column portion of the squeezing member 106 towards the liquid adding chamber 1. Furthermore, it will drive the sealing ring 110 and the connecting frame 102 towards the liquid adding chamber 1, causing the deformation spring 105 to be compressed. At this time, the seal of the liquid seepage hole 101 is released, and the cleaning liquid will flow out through the cylindrical portion groove 111 onto the wiping material. The user can make the cleaning liquid adhere to the wiping material while cleaning the wiping material on the mop head up and down. After cleaning the wiping material, when the mop head is about to be pulled out, the elastic force of the deformation spring 105 will cause the connecting frame 102 and the sealing ring 110 to return to their original positions, and the squeezing member 106 will also return to its original position. The sealing ring 110 will seal the liquid seepage hole 101, and the cleaning liquid will no longer flow out. The cleaning liquid adding device in this embodiment attaches the cleaning agent to the wiping material while cleaning the wiping material of the mop head, avoiding the risk that the cleaning liquid may spill on the ground or other non-target areas, causing unnecessary cleaning burden, avoiding manual addition again, realizing convenient and automatic addition of cleaning liquid, saving time and effort, reducing the waste of cleaning liquid, improving the cleaning efficiency, ensuring the cleaning effect, and enhancing the user experience.

[0054] Above the liquid adding chamber 1, there is a liquid adding chamber opening 112, which is closed by a cover plate 113. The cover plate 113 is connected to a sealing plate 114. There is a liquid adding hole 115 on the cover plate 113, and a sealing plate convex groove 116 is provided on the sealing plate 114. The sealing plate convex groove 116 is inserted into the liquid adding hole 115. Through the insertion of the sealing plate convex groove 116 into the liquid adding hole 115, the tight connection between the cover plate 113 and the sealing plate 114 is realized, effectively reducing the risk of liquid leakage from the liquid adding chamber opening 112 and improving the sealing performance of the liquid adding chamber 1. When the user needs to add cleaning liquid into the liquid adding chamber 1, just pull out the sealing plate convex groove 116 from the liquid adding hole 115, and then the liquid adding operation can be carried out through the liquid adding hole 115. After the liquid adding is completed, insert the sealing plate convex groove 116 back into the liquid adding hole 115 to close the liquid adding chamber 1, and the operation is simple and convenient.

[0055] The cleaning liquid adding device for the cleaning tool provided in this embodiment, during specific application, pulls out the sealing plate convex groove 116 from the liquid adding hole 115 to add cleaning liquid into the liquid adding chamber 1. After the addition is completed, inserts the sealing plate convex groove 116 back into the liquid adding hole 115 to close the liquid adding chamber 1. Then, move the mop head up and down in the cleaning tool, so that the wiping material on the mop head squeezes the head 107 of the squeezing member 106, driving the column part of the squeezing member 106 to move towards the liquid adding chamber 1, and further driving the sealing ring 110 and the connecting frame 102 to move towards the liquid adding chamber 1, causing the deformation spring 105 to be compressed and the seal of the liquid seepage hole 101 to be released. The cleaning liquid flows out through the cylindrical part groove 111 onto the wiping material to complete the cleaning of the wiping material. When the wiping material is cleaned, immediately pull out the mop head from the cleaning tool. The elastic force of the deformation spring 105 will cause the connecting frame 102, the sealing ring 110, and the squeezing member 106 to return to their original positions. The sealing ring 110 will seal the liquid seepage hole 101, and the cleaning liquid will no longer flow out. The user can hold the mop head and wipe the surface to be wiped.

[0056] Second Embodiment

[0057] This embodiment provides a mop bucket, as Figures 4 - 6 shown, including the cleaning liquid adding device in the first embodiment, and further including a bucket body 2. A bucket cover 201 is connected to the bucket body 2. A cleaning socket 202 is provided on the bucket cover 201. The liquid adding chamber 1 is arranged at the edge of the cleaning socket 202. The bucket cover 201 further includes a water squeezing socket 203. The water squeezing socket 203 is arranged in parallel with the cleaning socket 202, making the mop bucket approximately square. The liquid seepage hole 101 is arranged on the side wall close to the cleaning socket 202. A C-shaped abutting plate 204 is further arranged in the liquid adding chamber 1. The other end of the deformation spring 105 abuts inside the abutting plate 204. Clamping plates 205 are hinged on the edges of opposite sides of the bucket cover 201. A clamping convex 206 is arranged at the lower part inside the clamping plate 205. Rotate the clamping plate 205 to make the clamping convex 206 clamp at the lower edge of the opening of the bucket body to clamp the bucket cover 201 on the bucket body 2, or rotate the clamping plate 205 to make the clamping convex 206 release the clamping at the lower edge of the opening of the bucket body to disassemble the bucket cover 201 from the bucket body 2. A rebound assembly is further arranged on the bucket cover 201. Preferably, rebound assemblies are arranged on both sides of the clamping plate 205. The rebound assembly can move up and down on the lower side of the bucket cover 201. When the clamping convex 206 clamps at the lower edge of the opening of the bucket body, the rebound assembly is compressed and the lower end of the rebound assembly presses against the upper edge of the opening of the bucket body. When the clamping convex 206 releases the clamping from the lower edge of the opening of the bucket body, the rebound assembly is released and then pushes the bucket cover 201 to bounce up from the bucket body 2. At the same time when the clamping convex 206 disengages, the rebound assembly restores deformation and pushes the bucket cover 201 away from the bucket body 2 to overcome the adhesion force between the bucket cover 201 and the bucket body 2. In this way, after rotating the clamping plate 205 to make the clamping convex 206 disengage from the lower edge, the bucket cover 201 can be very conveniently and quickly removed from the bucket body 2.

[0058] Specifically, the rebound assembly includes a pipe column 207. The upper end of the pipe column 207 is movably connected to the bucket lid 201, and the lower end of the pipe column 207 can be pressed against the upper edge of the opening of the bucket body. The pipe column 207 is tubular with an opening at the upper part. A first spring 208 is arranged inside the pipe column 207. The upper end of the first spring 208 is connected to the bucket lid 201, and the lower end of the first spring 208 is connected to the inner bottom surface of the pipe column 207. When the bucket lid 201 is connected to the bucket body 2, the first spring 208 is compressed. Further, the bucket lid 201 includes an outer ring 225. An upwardly extending lug 209 is arranged on the opening edge of the pipe column 207. An outwardly extending tongue 210 is arranged at the end of the lug 209. A clamping hole 211 is arranged on the outer ring 225. The size of the tongue 210 is larger than that of the clamping hole 211. In this way, after the tongue 210 passes through the clamping hole 211 from bottom to top, it will be stuck on the upper side of the clamping hole 211, thereby connecting the pipe column 207 to the bucket lid 201. At this time, the lug 209 moves up and down in the clamping hole 211 to provide a space for the deformation of the first spring 208. The rebound assembly further includes a second spring 212. One end of the second spring 212 is connected to the bucket lid 201, and the other end is connected to the clamping plate 205. When the clamping projection 206 is clamped on the lower edge of the opening of the bucket body, the second spring 212 is compressed and its width becomes smaller. When the clamping projection 206 is disengaged from the lower edge of the opening of the bucket body, the second spring 212 is released and then pushes the clamping plate 205 to open quickly, which can prevent the clamping plate 205 from opening insufficiently, and the clamping projection 206 is still clamped on the lower edge of the opening of the bucket body, and the rebound assembly cannot quickly bounce up the bucket lid 201.

[0059] On the cleaning socket 202, there are oppositely arranged brush bristles 213 and a cleaning roller 214. The brush bristles 213 are located below the liquid adding bin 1 and protrude from the side wall of the cleaning socket 202. The two ends of the brush bristles 213 are bent towards the middle, making the overall shape of the brush bristles 213 be C-shaped. When the flat mop head moves up and down between the brush bristles 213 and the cleaning roller 214, the side surface and the front surface of the flat mop head are surrounded by the brush bristles 213. Thus, the brush bristles 213 clean the lower surface and the side surface of the flat mop head and scrape off the dirt on the flat mop head, thereby realizing the comprehensive scraping and cleaning of the flat mop head. The cleaning roller 214 is rotatably connected to a first support shaft 215. The first support shaft 215 is arranged on the edge of the cleaning socket 202 on the side opposite to the brush bristles 213. When the flat mop head moves up and down, the cleaning roller 214 supports the flat mop head to move on the brush bristles 213 and the cleaning roller 214 rotates following the up and down movement of the flat mop head.

[0060] The water squeezing socket 203 is provided with a water squeezing roller 216 and a water squeezing part. The water squeezing roller 216 is installed on a mounting bracket 217, and the mounting bracket 217 is arranged on the side wall of the water squeezing socket 203. The water squeezing roller 216 provides a supporting force for the up and down movement of the flat mop head in the water squeezing socket 203. The water squeezing part includes a first water squeezing plate 218 and a second water squeezing plate 219 which are oppositely arranged. The distances from the two water squeezing plates to the water squeezing roller 216 are different. The water squeezing roller 216 is arranged between the first water squeezing plate 218 and the second water squeezing plate 219, so that the flat mop head can move up and down between the first water squeezing plate 218 and the water squeezing roller 216 and / or the flat mop head can move up and down between the second water squeezing plate 219 and the water squeezing roller 216 to squeeze and dry the water. By setting two water squeezing plates with different distances, the squeezing forces of the two water squeezing plates on the flat mop head are different, and the humidity of the flat mop head after drying is also inconsistent, so that it can be suitable for wiping wooden floors and floor tiles, increasing the applicable range and improving the user experience.

[0061] The bucket body 2 includes a cleaning area 220 and a water squeezing area 221. The cleaning area 220 corresponds to the cleaning socket 202 to clean the flat mop head, and the water squeezing area 221 corresponds to the water squeezing socket 203 to squeeze and dry the flat mop head. A first water outlet 222 is arranged in the cleaning area 220, and a second water outlet 223 is arranged in the water squeezing area 221. The first water outlet 222 and the second water outlet 223 are arranged on the side wall of the bucket body 2 to discharge the sewage. The mop bucket further includes a handle 224 to facilitate the movement of the mop bucket. The handle 224 is rotatably connected to the bucket body 2. On the bucket cover 201, there are also marks for drying wooden floors, marks for drying floor tiles, and marks for cleaning with cleaning liquid, which makes it more convenient for users to identify and recognize, improving the user experience.

[0062] During the specific application process of the mop bucket provided in this embodiment, when in use, the cleaning area 220 is filled with water. The sealing plate convex groove 116 is pulled out from the liquid adding hole 115 to add cleaning liquid into the liquid adding chamber 1. After the liquid adding is completed, the sealing plate convex groove 116 is inserted back into the liquid adding hole 115. The flat mop head to be cleaned is inserted between the bristles 213 and the cleaning roller 214 in the cleaning socket 202, and an external force is used to make the flat mop head move up and down. The wiping material on the flat mop head will squeeze the head 107 of the squeezing member 106, driving the column part of the squeezing member 106 to move towards the liquid adding chamber 1. Further, it will drive the sealing ring 110 and the connecting frame 102 to move towards the liquid adding chamber 1, causing the deformation spring 105 to be compressed. At this time, the seal of the liquid seepage hole 101 is released, and the cleaning liquid will flow out to the wiping material through the cylindrical part groove 111. After the cleaning is completed, the flat mop head is pulled out. The elastic force of the deformation spring 105 will cause the connecting frame 102 and the sealing ring 110 to return to their original positions, and the squeezing member 106 will also return to its original position. The sealing ring 110 will seal the liquid seepage hole 101, and the cleaning liquid will no longer flow out. Then, the flat mop head is placed in the water squeezing socket 203 and moved up and down, and the flat mop head is scraped and squeezed dry by the first water squeezing plate 218 or the second water squeezing plate 219. When the mop bucket needs to be cleaned, the rotating card plate 205 is rotated so that the convex projection 206 disengages from the lower edge of the opening of the bucket body. At this time, the first spring 208 resumes deformation, and the first spring 208 pushes the bucket cover 201 to pop open from the bucket body 2, and the elastic force of the second spring 212 pushes the card plate 205 to open quickly to prevent the convex projection 206 from being insufficiently disengaged, so that the bucket cover 201 can be conveniently removed for cleaning. After the bucket cover 201 is cleaned, the bucket cover 201 is placed at the opening of the bucket body, and it is pressed down so that the pipe column 207 presses against the upper edge and compresses the first spring 208, and the convex plate is clamped on the lower edge of the opening of the bucket body, realizing the installation of the bucket cover 201.

[0063] Third Embodiment

[0064] This embodiment provides a narrow-slit type mop bucket, as Figures 7 - 10 shown, including the cleaning liquid adding device in the first embodiment, and further including a bucket body 2. A bucket cover 201 is connected to the bucket body 2. A cleaning socket 202 is provided on the bucket cover 201. The liquid adding chamber 1 is arranged at the edge of the cleaning socket 202. The bucket cover 201 further includes a water squeezing socket 203, and the water squeezing socket 203 is arranged side by side with the cleaning socket 202, making the mop bucket in a narrow-slit type. The narrow-slit type mop bucket in this embodiment can also conveniently and quickly remove the bucket cover 201 from the bucket body 2. Its components and connection relationships are the same as those in the second embodiment, and will not be elaborated here.

[0065] In the water squeezing socket 203 of this embodiment, there are a first insertion position 301 and a second insertion position 302. The first insertion position 301 and the second insertion position 302 are arranged oppositely, and a first roller 303 is provided between the first insertion position 301 and the second insertion position 302. There are two first rollers 303, which are respectively arranged on both sides of the water squeezing socket 203. A first water leakage port 304 is provided on the side wall of the first insertion position 301, and a second water leakage port 305 is provided on the side wall of the second insertion position 302. A first water squeezing scraper 306 is movably connected in the first water leakage port 304, and a second water squeezing scraper 307 is movably connected in the second water leakage port 305. The distance between the first water leakage port 304 and the first roller 303 is greater than the distance between the second water leakage port 305 and the first roller 303. When the mop head is inserted into the first insertion position 301, the supporting squeezing force formed by the first roller 303 on the mop head is relatively small, and at this time, the drying effect on the mop head is relatively poor, which can be used to wipe the floor with relatively weak dirt or wooden floor; when the mop head is inserted into the second insertion position 302, the supporting squeezing force formed by the first roller 303 on the mop head is relatively large, and at this time, the drying effect on the mop head is relatively strong, which can be used to wipe the floor with relatively strong dirt or floor tiles.

[0066] On the upper end surface of the first water squeezing scraper 306, there are a number of uniformly and parallelly arranged support plates 308. The ends of the support plates 308 are arc-shaped, and a reinforcing rib is provided on the lower end surface of the first water squeezing scraper 306. When the flat mop head is inserted downward into the first insertion position 301, the support plates 308 guide the mop head, and the first water squeezing scraper 306 is stuck in the first water leakage port 304 and is approximately perpendicular to the mop head. At this time, the first water squeezing scraper 306 scrapes the mop head, and the water scraped out flows out from the water leakage port along the gap between two adjacent support plates 308. The second water squeezing scraper 307 is a hollow tubular structure, and the upper surface of the second water squeezing scraper 307 gradually slopes downward from the side far from the first roller 303 to the side close to the first roller 303. The surface of the first water squeezing scraper 306 on the side close to the first roller 303 is a vertical plane to squeeze and dry the surface of the flat mop. In this way, the vertical plane serves as the scraping surface and the edge serves as the scraping edge, which has a better cleaning and scraping effect on the wiping object of the flat mop head.

[0067] The cleaning socket 202 is provided with a third socket 309 and a fourth socket 310. The third socket 309 and the fourth socket 310 are arranged opposite to each other, and a second roller 311 is provided between the third socket 309 and the fourth socket 310. There are two second rollers 311, which are respectively arranged on both sides of the cleaning socket 202. The liquid adding bin 1 is arranged on the upper edge of the fourth socket to facilitate attaching the cleaning liquid to the wiping object when cleaning the wiping object. The first scraping tooth plate 312 is provided on the third socket. A number of scraping tooth ribs 313 are provided above the first scraping tooth plate 312, and water passing holes 314 are formed between adjacent scraping tooth ribs 313; the second scraping tooth plate 315 is provided on the fourth socket, and the liquid adding bin 1 is arranged above the second scraping tooth plate 315. The first scraping tooth plate 312 and the second scraping tooth plate 315 can scrape off the hair and the like wound on the external mop head. The end face of the scraping tooth rib 313 above the first scraping tooth plate 312 is arc-shaped. The arc-shaped end face of the scraping tooth rib 313 supports and guides the external mop head, and the scraping tooth rib 313 squeezes the mop head to squeeze out the sewage on the mop head, which is more conducive to cleaning the mop head. Other components in this embodiment are the same as or similar to those in the second embodiment, and will not be described in detail here.

[0068] In the narrow-slit type mop bucket provided in this embodiment, during the specific application process, the cleaning area 220 is filled with water. The sealing plate convex groove 116 is pulled out from the liquid adding hole 115 to add the cleaning liquid into the liquid adding bin 1. After the liquid adding is completed, the sealing plate convex groove 116 is inserted back into the liquid adding hole 115. The flat mop head to be cleaned is inserted into the fourth socket 310 of the cleaning socket 202, and an external force is used to make the flat mop head move up and down. The wiping object on the flat mop head will squeeze the head 107 of the squeezing member 106, driving the column part of the squeezing member 106 to move towards the liquid adding bin 1. Further, it will drive the sealing ring 110 and the connecting frame 102 to move towards the liquid adding bin 1, so that the deformation spring 105 is compressed. At this time, the seal of the liquid seepage hole 101 is released, and the cleaning liquid will flow out to the wiping object through the cylindrical part groove 111. After the cleaning is completed, the flat mop head is pulled out. The elastic force of the deformation spring 105 will make the connecting frame 102 and the sealing ring 110 return to their original positions, and the squeezing member 106 will also return to its original position. The sealing ring 110 will seal the liquid seepage hole 101, and the cleaning liquid will no longer flow out. Then, the flat mop head is put into the water squeezing socket 203 and moved up and down, and the flat mop head is scraped dry and dehydrated by the first water squeezing scraping plate 306 or the second water squeezing scraping plate 307. When the mop bucket needs to be cleaned, the rotating card plate 205 is rotated so that the convex 206 is disengaged from the lower edge of the opening of the bucket body, so that the bucket cover 201 can be conveniently removed for cleaning. After the cleaning of the bucket cover 201 is completed, the bucket cover 201 is placed at the opening of the bucket body, and it is pressed down so that the tube column 207 presses against the upper edge, and the convex 206 is clamped on the lower edge of the opening of the bucket body, realizing the installation of the bucket cover 201.

A liquid adding bin 1 is arranged on the water squeezing cover plate 404. Two symmetrically arranged C-shaped fixing plates 405 are arranged in the liquid adding bin 1. A connecting frame 102 is movably connected in the fixing plates 405. The connecting frame 102 matches the fixing plates 405 so that the connecting frame 102 can move along the width direction of the two fixing plates 405. The C-shaped fixing plates 405 play a guiding role in the movement of the connecting frame 102.

[0071] The smoothing opening part 403 further includes a water squeezing frame 406. A through opening 407 is formed between the water squeezing cover plate 404 and the water squeezing frame 406. When the mop plate 401 moves in the through opening 407, the wiping object will abut against and squeeze the head of the squeezing part, so that the cleaning liquid flows out onto the wiping object to clean the wiping object with the cleaning liquid. When the mop plate moves outside the through opening, the wiping object will not abut against the head of the squeezing part and will no longer squeeze the squeezing part, so that the cleaning liquid will not leak out, further avoiding the waste of the cleaning liquid. First clamping grooves 408 and first clamping plates 409 are arranged at both ends of the water squeezing cover plate 404. Second clamping grooves 410 and second clamping plates 411 are arranged on the water squeezing frame 406. The first clamping plate 409 can be clamped and matched to the second clamping groove 410, and the second clamping plate 411 can be clamped and matched to the first clamping groove 408, so that the water squeezing cover plate 404 and the water squeezing frame 406 are clamped and matched, and the water squeezing cover plate 404 and the water squeezing frame 406 will not move in the front, rear, left, and right directions, ensuring the stability of the structure.

[0072] The water squeezing cover plate 404 and the water squeezing rack 406 are connected to the clamping piece 412 after being snap-fitted. The upper end surface of the water squeezing cover plate 404 is provided with a first slot or a first protrusion, and the clamping piece 412 is provided with a first protrusion or a first slot that cooperates with the first slot or the first protrusion. The lower end surface of the water squeezing rack 406 is provided with a second slot or a second protrusion, and the clamping piece 412 is provided with a second protrusion or a second slot that cooperates with the second slot or the second protrusion. When the water squeezing cover plate 404 and the water squeezing rack 406 are snap-fitted, one end of the clamping piece 412 can be snap-fitted to the water squeezing cover plate 404, and the other end of the clamping piece 412 can be snap-fitted to the water squeezing rack 406, so that the clamping piece 412 covers the end portions of the water squeezing cover plate 404 and the water squeezing rack 406 after they are connected. In this embodiment, the upper end surface of the water squeezing cover plate 404 is provided with a first slot 413, the upper end of the clamping piece 412 is provided with a first protrusion 414, the lower end surface of the water squeezing frame 406 is provided with a second slot 415, and the lower end of the clamping piece 412 is provided with a second protrusion 416. During installation, the water squeezing cover plate 404 and the water squeezing rack 406 are firstly connected into one body, and then the clamping member 412 is covered on the outside of the water squeezing cover plate 404 and the water squeezing rack 406, and the first protrusion 414 is clamped in the first clamping groove 413, and the second protrusion 416 is clamped in the second clamping groove 415 to realize the connection of the clamping members 412 on both sides. When the water squeezing sleeve assembly 402 is used to clean the mop plate 401, the squeezing force generated on the mop plate 401 will directly act on the clamping member 412, and is transmitted to the connection position between the first clamping groove 413 and the first protrusion 414, and the second clamping groove 415 and the second protrusion 416 through the two ends of the clamping member 412, so that the mop is more difficult to be damaged, and the service life of the mop is guaranteed. In addition, by embedding the clamping member 412 on the water squeezing cover plate 404 and the water squeezing rack 406, the aesthetic sense is increased.

[0073] A scraper 417 is rotatably connected in the water squeezing cover plate 404, and a water squeezing frame roller 418 is symmetrically provided on the water squeezing frame 406. The water squeezing frame roller 418 can roll along the length direction of the mop board 401, so that when the mop board 401 moves up and down through the through opening 407, the scraper 417 scrapes and cleans the wipes, and the liquid tank 1 attaches the detergent to the surface of the wipes and squeezes and dehydrates the wipes, and the water squeezing frame roller 418 supports the mop board 401, so that the mop board 401 moves up and down smoothly in the through opening 407. The water squeezing and stroking sleeve assembly 402 also includes a connecting sleeve and a connecting tube connected to each other, the connecting sleeve and the connecting tube are sleeved on the outer periphery of the mop rod 4, and the connecting sleeve is connected to the water squeezing frame 406.

The connecting component includes a first connecting piece 420 and a second connecting piece 421. The first connecting piece 420 is connected to the second connecting piece 421 through a steering block 423. The first connecting piece 420 is used to be connected to the mop plate 401, and the second connecting piece 421 is used to be connected to the mop rod 4 to realize the connection between the connecting component and the mop plate 401.

[0075] A locking part 424 is provided on the connecting cylinder. When the locking part 424 is opened, the water squeezing and smoothing sleeve assembly 402 can slide relative to the mop rod 4 so as to squeeze the wiping object on the mop plate 401 in the through hole 407. When the locking part 424 is locked, the water squeezing and smoothing sleeve assembly 402 is fixed on the mop rod 4. By providing the locking part 424, when moving the water squeezing and smoothing sleeve assembly 402 up and down, the state of the locking part 424 can be switched more conveniently to switch the state of the water squeezing sleeve. Hanging teeth 425 for connecting with the wiping object are provided at both ends of the mop plate 401. The wiping object is connected to the mop plate 401 through the hanging teeth 425 at both ends of the mop plate 401 to realize the cleaning of the floor. The two sides of the mop plate 401 are respectively connected to the scraping strips 426. If there is dust, garbage or water stains on the floor, the scraping strips 426 can be used for cleaning first, and then the wiping object can be used for cleaning, enhancing the cleaning effect.

[0076] In the specific application process of the hand-free flat mop provided in this embodiment, the water squeezing and smoothing sleeve assembly 402 is sleeved on the mop rod 4, and the locking part 424 is rotated to make the locking part 424 in a loose state. At this time, there is a gap between the mop rod 4 and the connecting cylinder. Hold the connecting cylinder and move the water squeezing and smoothing sleeve assembly 402 up and down along the mop rod 4, and the mop plate 401 moves in the through hole 407. The wiping object on the mop plate 401 squeezes the head 107 of the squeezing part 106, so that the cleaning liquid flows out from the liquid adding bin 1 onto the wiping object while the scraping plate 417 squeezes the wiping object in the through hole 407 and performs cleaning and scraping; when the cleaning of the wiping object is completed, rotate the locking part 424 to make the locking part 424 in a locked state, so that the mop rod 4 and the connecting cylinder cannot move relatively, and then the water squeezing and smoothing sleeve assembly 402 is fixed on the mop rod 4. The user can hold the flat mop to conveniently clean the ground.
