Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a hands-free mop. Background Art

[0002] Hands-free mops are popular for their simple structure and efficient, convenient cleaning process. Existing hands-free mops have a similar structure, including a flat mop and a stroking cover wrapped around the flat mop. The flat mop includes a mop plate with a wiping material on the back of the mop plate and a mop rod rotatably connected to the front of the mop plate. People use the mop rod to clean the floor. The stroking cover includes a connecting portion that is mounted on the mop rod through the connecting portion. A stroking head is provided at the end of the connecting portion, and a slot is left in the stroking head. The connecting portion slides on the mop rod, allowing the mop plate to move within the slot, and a squeezing mechanism in the slot squeezes and dehydrates the wiping material.

[0003] However, the existing hands-free flat mop still has some defects: 1. The front of the mop plate is connected to the mop rod through a connecting part, and the connecting part and the mop rod are often connected by a snap connection, that is, a groove is provided on the connecting part, the groove is connected to a spring piece, one end of the spring piece is connected to the groove wall, and the other end is suspended, and a protrusion is connected to the suspended end, and a through groove matching the protrusion is provided at one end of the mop rod, and the protrusion is inserted into the through groove by deforming the spring piece to achieve the connection between the connecting part and the mop rod. However, since one end of the spring piece is suspended, the connection is poor, and the spring piece is easily damaged after a long period of use, that is, the mop rod and the connecting part are damaged. 1. The mop handle is not easy to be detached and its service life is shortened; 2. The existing stroking cover often includes a connecting portion that is sleeved on the outer periphery of the mop rod and can slide along the mop rod, and a stroking head is provided at the end of the connecting portion. The stroking head often includes an upper stroking head part and a lower stroking head part. The upper stroking head part and the connecting portion are integrally formed, and its size is fixed. Different flat mops need to be equipped with stroking covers of different sizes. When the mop rod or the mop plate of the flat mop is longer, a longer connecting portion is required to be used with it, so as to facilitate the cleaning of the wiping objects. However, if the mop rod or the mop plate is shorter, a shorter connecting portion is more practical. Therefore, the existing stroking cover structure has low versatility. At the same time, the upper and lower stroke head parts are plugged and / or snap-fitted together. When the stroke cover is used to clean or squeeze out the wipes on the mop board, the upper and lower stroke head parts may become loose or even detached due to excessive squeezing force or squeezing angle problems. The structural stability is poor, and especially when used for a long time, there is wear between the various components, which makes it easier for the upper and lower stroke head parts to detach during use.

[0029] Preferably, both ends of the mop plate are provided with hanging teeth connected to the wiping object.

[0030] In the above technical solution, the stroking cover includes a stroking head, a connecting portion, and a handle. The stroking head, the connecting portion, and the handle are detachably connected. Compared with the one-piece stroking covers in the prior art, the stroking cover with an assembled structure has wider versatility. It only needs to change the length of the connecting portion to adapt the stroking cover to the size change of the mop board, thereby facilitating the processing and manufacturing of the stroking cover. Furthermore, the connecting portion is generally in the shape of an elongated strip, and the cross-section of the connecting portion is a C-shaped with a notch. It can be processed through an extrusion process to form a strip with the same cross-section as the connecting portion. In this way, the required length of the connecting portion can be cut according to the size of the mop board. At this time, the cut connection portion can be assembled with the stroking head and the handle. Therefore, when the size of the mop board changes, there is no need to replace or add a stroking cover mold, which can further reduce processing costs.

[0031] The stroking head includes an upper extrusion frame and a lower extrusion frame. A clamping groove and a clamping support plate are respectively provided at both ends of the upper extrusion frame. A clamping groove and a clamping support plate are also provided on the lower extrusion frame. The clamping support plate of the upper extrusion frame is inserted into the clamping groove of the lower extrusion frame, and the clamping support plate of the lower extrusion frame is inserted into the clamping groove of the upper extrusion frame to prevent the upper extrusion frame and the lower extrusion frame from moving in the front, back, left and right directions when the clamping parts are buckled, which causes difficulties in installing the clamping parts. The locking plate is secured to a position adjacent to the lower frame, and the locking plate is secured to a position adjacent to the lower frame when the locking plate is engaged. In a vertical plane, when the mop board is cleaned with the stroke sleeve, the extrusion assembly generates an extrusion force on the mop board, and the stroke sleeve is subjected to the outward thrust generated by the mop board on the stroke sleeve, so that the upper extrusion frame and the lower extrusion frame of the stroke sleeve are deformed in the direction of moving away from each other. At this time, if the two ends of the upper extrusion frame and the lower extrusion frame are connected by direct insertion and clamping, then in the process of using the stroke sleeve to clean or scrape the mop board, it is easy to cause the upper extrusion frame and the lower extrusion frame to separate. However, by the clamping member wrapped around the end portion where the upper extrusion frame and the lower extrusion frame are connected, the thrust directly acts on the clamping member, and is transmitted to the connection position of the first clamping groove and the first protrusion, and the second clamping groove and the second protrusion through the two ends of the clamping member, which is less likely to be damaged.

[0032] The connecting member is provided with a long, strip-shaped locking groove, with a spring plate connected to it along its length and at its center. A through hole is provided on each side of the spring plate, away from the sidewalls of the locking groove, facilitating deformation of the spring plate during the locking process. Both ends of the spring plate are connected to the locking groove, resulting in a strong connection and preventing damage to the spring plate even after prolonged use, thereby preventing the mop rod from separating from the connecting portion and increasing its service life. The locking protrusion is tilted toward the end closer to the mop rod, guiding the mop rod when the locking protrusion contacts the locking hole during connection of the second connecting member to the mop rod, making it easier for the locking protrusion to lock into the locking hole. Furthermore, the height of the locking protrusion, which is farther from the mop rod, is higher, making it more difficult for the two to separate after the locking protrusion and the locking hole are locked.

DETAILED DESCRIPTION

[0045] The present invention will be further described below with reference to the accompanying drawings:

[0046] like Figures 1 to 11As shown, the hands-free mop includes a flat mop, which includes a mop rod 11 and a mop plate 143 movably connected to the mop rod 11. A wiper is provided on the mop plate 143, and the wiper is connected to the mop plate 143 through hanging teeth 144 at both ends of the mop plate 143. A sleeve 148 that can move up and down is provided on the mop rod 11. The stroking sleeve 148 includes a stroking head 21, a connecting portion 232 and a handle 237. A through-hole 221 for the mop plate 143 to pass through is provided on the stroking head 21, and a squeezing mechanism 224 is provided in the through-hole 221. The squeezing mechanism 224 squeezes the wiping material on the mop plate 143. The connecting portion 232 and the handle 237 are sleeved on the mop rod 11. A first positioning portion 211 is provided on the stroking head 21, and a second positioning portion 244 is provided at one end of the handle 237. The connecting portion 232 is assembled and connected with the stroking head 21 and the handle 237 through the first positioning portion 211 and the second positioning portion 244 to form the stroking sleeve 148. The method is simple and easy to install. The handle 237 drives the connecting portion 232 to slide on the mop rod 11. This assembly method of forming the sleeve 148 allows for greater versatility. Simply changing the length of the connecting portion 232 allows the sleeve 148 to be adapted to mop plates of varying lengths. Furthermore, the sleeve 148 can be extruded into a strip having the same cross-section as the connecting portion 232. The connecting portion 232 can then be cut to the desired length based on the size of the mop plate. Therefore, when the mop plate size changes, there is no need to replace or add a new sleeve 148 mold. This means that the assembled sleeve 148 can be used for flat mops of various sizes, further reducing manufacturing costs. The connecting portion 232 has a C-shaped cross-section with a notch 233, and covers the outside of the mop rod 11. Limiting features are provided on either side of the notch to prevent a gap between the connecting portion and the mop rod. The first positioning portion 211 and the second positioning portion 244 both conform to the cross-section of the connecting portion 232. One end of the connecting portion 232 is inserted and fixed to the first positioning portion 211, and the other end is inserted and fixed to the second positioning portion 244. This secures the connecting portion 232, the mopping head 21, and the handle 237 together to form the mopping sleeve 148. Positioning edges 246 are provided at the bottom of each of the first positioning portion 211 and the second positioning portion 244, securing the connecting portion 232. A positioning strip 236 is provided on the side of the limiting portion 234 near the mop handle 11. A bolt protrusion 113 is provided on the mop handle 11. The bolt protrusion 113 and the positioning strip 236 cooperate to limit each other, thereby preventing the mopping sleeve 148 from rotating.

[0047] In this embodiment, the stroking head 21 includes an upper extrusion frame 212, a lower extrusion frame 215 that cooperates with the upper extrusion frame 212, and a snap-fitting member 217 that connects the upper extrusion frame 212 and the lower extrusion frame 215. A through-hole 221 is formed between the upper extrusion frame 212 and the lower extrusion frame 215. A snap-fitting groove 222 and a snap-fitting support plate 223 are respectively provided at both ends of the upper extrusion frame 212. The snap-fitting support plate 223 of the upper extrusion frame 212 is inserted into the snap-fitting groove 222 of the lower extrusion frame 215, and the snap-fitting support plate 223 of the lower extrusion frame 215 is disposed in the snap-fitting groove 222 of the upper extrusion frame 212. This prevents the upper extrusion frame 212 and the lower extrusion frame 215 from moving forward, backward, left, or right when the snap-fitting member 217 is engaged, which would otherwise cause difficulty in installing the snap-fitting member 217. Furthermore, the locking member 217 is provided at the end portion where the upper extrusion frame 212 and the lower extrusion frame 215 are connected, and a first locking groove 216 or a first protrusion is provided at both ends of the upper end surface of the upper extrusion frame 212, and a second locking groove 214 or a second protrusion is provided at both ends of the lower end surface of the lower extrusion frame 215, and a first protrusion 218 or a first locking groove and a second protrusion 219 or a second locking groove are correspondingly provided on the locking member 217. Taking the example of a first card slot 216 provided on the upper extrusion frame 212 and a second card slot 214 provided on the lower extrusion frame 215, during installation, the card connection between the upper extrusion frame 212 and the lower extrusion frame 215 is first achieved by inserting the card support plate 223 into the card slot 222, and the card connection between the upper extrusion frame 212 and the lower extrusion frame 215 is completed by the card engaging piece 217 wrapped around the outer side of the upper extrusion frame 212 and the lower extrusion frame 215 and the first protrusion 218 is carded in the first card slot, and the second protrusion 219 is carded in the second card slot to complete the connection between the upper and lower extrusion frames 215, with strong connectivity. At the same time, the connection between the upper extrusion frame 212 and the card engaging piece 217 is above the upper extrusion frame 212, and the connection between the lower extrusion frame 215 and the card engaging piece 217 is below the lower extrusion frame, that is, the connection between the upper extrusion frame 212 and the lower extrusion frame 215 and the card engaging piece 217 is not in a vertical plane. During the cleaning process of the mop board, the extrusion assembly generates an extrusion force on the mop board, and the sleeve 148 is subjected to the outward thrust generated by the mop board on the sleeve 148, causing the upper extrusion frame 212 and the lower extrusion frame 215 of the sleeve 148 to deform in the direction away from each other. At this time, if the two ends of the upper extrusion frame 212 and the lower extrusion frame 215 are connected by direct insertion and clamping, then in the process of using the sleeve 148 to clean or scrape the flat mop board, it is easy to cause the upper extrusion frame 212 and the lower extrusion frame 215 to separate. The clamping member 217 is wrapped around the end portion where the upper extrusion frame 212 and the lower extrusion frame 215 are connected, and the thrust acts directly on the clamping member 217, and is transmitted to the connection position of the first card slot and the first protrusion 218, and the second card slot and the second protrusion 219 through the two ends of the clamping member 217, which is less likely to be damaged.Furthermore, the engaging member is embedded in the upper extrusion frame and the lower extrusion frame, which is more beautiful. At the same time, a slope 220 is provided on the side of the second protrusion 219 away from the engaging member 217, which makes it easier for the engaging member 217 to engage.

[0048] The squeezing mechanism 224 includes a scraper 225 and a roller 226. The scraper 225 and roller are rotatably mounted on the upper squeezing frame 212. The lower squeezing frame 215 is provided with a roller bracket, on which a roller, preferably a roller, is mounted. The roller and squeezing mechanism 224 are arranged relative to each other, and the mop plate reciprocates between the roller and the squeezing mechanism 224. The rotation direction of the roller aligns with the movement direction of the mop plate. As the mop plate moves up and down through the opening 221, the scraper scrapes and cleans the mop material, while the roller 226 squeezes and dehydrates the mop material. The roller supports the mop plate to move smoothly back and forth within the opening 221. Furthermore, the upper squeezing frame 212 is equipped with three sets of rollers to perform multiple squeezing operations. The three sets of rollers 226 are all hollow and connected to the upper extrusion frame 212 via mounting members 227. The mounting members 227 include a horizontal plate 228. A sleeve 229 is provided on one side of the horizontal plate 228, which is inserted into the ends of the rollers 226. At least two protruding shafts 230 are provided on the other side of the horizontal plate 228. The sidewalls of the upper extrusion frame 212 are provided with through holes that mate with the protruding shafts 230. The protruding shafts 230 are inserted into the through holes to connect the upper extrusion frame 212 to the rollers. When the three sets of rollers 226 squeeze and dehydrate the wipes, the rollers 226 rotate. Because the sleeves 229 are inserted at both ends, the rollers 226 do not fall out during rotation, thus enhancing connectivity. Furthermore, a limit plate 231 is provided on the upper extrusion frame 212. The limit plate 231 is arranged between the scraper 225 and the roller 226. When the scraper 225 is perpendicular to the mop plate 143, the limit plate 231 engages the scraper 225. When the mop plate 143 passes through the opening 221, it drives the scraper 225 to rotate backward, so that the scraper 225 abuts against the limit plate 231. At this time, the width of the opening 221 is minimized, and the scraping force on the wiped object is maximized, that is, the garbage on the wiped object is cleaned very conveniently. Furthermore, a reinforcing rib is provided on the side of the scraper 225 away from the limit plate 231.

[0049] In a preferred embodiment, a locking assembly 238 is provided on the handle 237. When the handle 237 is gripped to move the sleeve 148 up and down, the state of the locking assembly 238 can be switched very conveniently. When the locking assembly 238 is in the open state, the stroking head 21 can slide up and down along the mop rod 11 to squeeze and clean the wiping material; when the locking assembly 238 is in the locked state, the stroking head 21 is fixed on the mop rod 11 to facilitate the wiping material to clean the floor. Furthermore, the locking assembly 238 includes a dial plate 239 and a clamping plate 240, on which a "locking mark" and a "relaxing mark" are provided. The end of the clamping plate 240 intersects with the middle part of the dial plate 239 and forms an angle. A pivot 241 is provided at the connection between the clamping plate 240 and the dial plate 239, and a locking hole 242 for the clamping plate 240 to rotate is provided on the handle 237. A hinge seat 243 cooperating with the pivot 241 is provided at the edge of the locking hole 242. The dial plate 239 drives the clamping plate 240 to rotate at the locking hole 242. The pull plate 239 is rotated toward the "release mark" side, driving the clamping plate 240 to retract to the lock hole 242. At this time, the locking assembly 238 is in the open state; the pull plate 239 is rotated toward the "lock mark" side and drives the clamping plate 240 to enter the handle 237 and protrude from the inner side wall of the handle 237.
