Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a squeezing sleeve for a flat mop which is convenient to fix and a flat mop. Background Art

[0002] Flat mops are chosen and used by more and more people because of their simple structure and convenient use. The existing flat mops generally have similar structures, including a mop rod and a mop head movably connected to the mop rod, and a wiping material for scrubbing the ground or glass is provided on the mop head. In order to realize self-cleaning and water squeezing of the mop, a slidable squeezing sleeve is arranged on the mop rod. The squeezing sleeve is sleeved on the mop rod through a connecting part, and a squeezing head with a squeezing opening is arranged at the end of the connecting part. By moving the flat mop board in the squeezing opening, the squeezing mechanism in the squeezing opening squeezes the wiping material on the mop board to dehydrate. To ensure that the squeezing sleeve moves linearly along the mop rod, a chute is arranged in the connecting part of the squeezing sleeve, and a protrusion moving along the chute is arranged on the mop rod. At the same time, a connected clamping structure is arranged at the lower end of the chute to fix the squeezing sleeve on the mop rod. When the mop board is cleaned, pull the squeezing sleeve upward forcefully, and the protrusion will cross over and be stuck at the clamping structure to fix the squeezing sleeve on the mop board. However, during the process of cleaning and squeezing the mop board, the protrusion is very easy to directly get stuck in the clamping structure from the chute. Especially when the mop board is quickly scraped and cleaned, the scraping and cleaning process will be stuck due to the protrusion clamping the clamping structure, which affects the user experience.

[0003] In addition, there is another fixing structure of the squeezing sleeve. A locking part is arranged at one end of the connecting part of the squeezing sleeve. By pulling the hand-held end of the locking part close to the mop rod side, the squeezing sleeve is fixed on the mop rod, or by pulling the hand-held end of the locking part away from the mop rod side to unlock, so that the squeezing sleeve can slide on the mop rod. However, this method requires one hand to fix the mop rod and the other hand to operate the locking part to complete the switching between the fixed state and the unlocked state, which is relatively inconvenient to operate.

Compared with the integral cleaning sleeve in the prior art, the assembled cleaning sleeve has greater versatility. Only by changing the length of the connecting part can the cleaning sleeve be adapted to the size change of the flat mop plate, thereby facilitating the processing and production of the cleaning sleeve. Further, the connecting part is integrally strip-shaped, and the cross-section of the connecting part is a C shape with a notch. A strip with the same cross-section as the connecting part can be formed by extrusion molding. In this way, the required length of the connecting part can be intercepted according to the size of the mop plate, and then the intercepted connecting part is assembled with the cleaning head and the handle. Therefore, when the size of the mop plate changes, it is not necessary to replace or add a cleaning sleeve mold for production, which can further reduce the processing cost.

[0030] A chuck is provided on the mop rod. The chuck can pre-clean the garbage such as hair attached to the wiping object to avoid it being wound around the scraping blade or the roller later and affecting the cleaning effect of the cleaning sleeve. After the pre-cleaning is completed, the chuck can be stored in the storage groove. Description of the Drawings

The handle 3 drives the connecting portion 2 to slide on the mop rod 7 of the flat mop. Preferably, the assembling method of the connecting portion 2 and the combing head 1 is any method or any combination of snap connection, plug connection or screw connection, and the assembling method of the connecting portion 2 and the handle 3 is any method or any combination of snap connection, plug connection or screw connection. By forming the combing sleeve in this assembling manner, the combing sleeve can have greater versatility, that is, only by changing the length of the connecting portion 2, the combing sleeve can be adapted to the mop plates of flat mops with different length dimensions. Further, it can be processed into a strip with the same cross-section as the connecting portion 2 by extrusion molding, and the connecting portion 2 with the required length is intercepted according to the size of the mop plate. Therefore, when the size of the mop plate changes, there is no need to replace or add a combing sleeve mold, that is, the combing sleeve assembled in this way can be used for flat mops of various sizes, further reducing the processing cost.

[0050] In this embodiment, a first positioning portion 12 is provided on the combing head 1, and a second positioning portion 31 is provided at one end of the handle 3. The connecting portion 2 is assembled and connected to the combing head 1 and the handle 3 through the first positioning portion 12 and the second positioning portion 31 to form a combing sleeve. Further, the cross-section of the connecting portion 2 is a C shape with a notch 21, and the connecting portion 2 covers the outside of the flat mop rod 7. The first positioning portion 12 and the second positioning portion 31 are both conformable to the cross-section of the connecting portion 2, and one end of the connecting portion 2 is inserted and fixed in the first positioning portion 12 and the other end is inserted and fixed in the second positioning portion 31, so that the connecting portion 2, the combing head 1 and the handle 3 are fixedly connected together. Further still, limiting portions 22 are provided on the edges on both sides of the notch 21. When the connecting portion 2 is sleeved on the outside of the mop rod 7, the limiting portions 22 can prevent the mop rod 7 from slipping out of the connecting portion 2.

[0060] In a preferred embodiment, a positioning projection 73 is provided on the mop rod 7, a first limiting edge 9 is provided on the wringing head 1, and a second limiting edge 10 is provided on the handle 3. When the wringing sleeve moves up and down to scrape and clean the mop plate 8, the positioning projection 73 limits the movement stroke of the first limiting edge 9 and the second limiting edge 10. That is, when the positioning projection 73 contacts the first limiting edge 9, the wringing sleeve moves to one end of the mop plate 8; when the positioning projection 73 contacts the second limiting edge 9, the wringing sleeve moves to the other end of the mop plate 8, thereby preventing the wringing sleeve from disengaging from the mop rod. In this embodiment, the first limiting edge 9 and the second limiting edge 10 can be positioning edges provided at the bottom of the first positioning portion 12 and the second positioning portion 31. An accommodation cavity for the connecting portion 2 is formed between the positioning edge and the side walls of the first positioning portion 12 and the second positioning portion 31, and it also limits the curling deformation of the connecting portion 2 and its disengagement from the first positioning portion 12 or the second positioning portion 31. Further, there are two positioning projections 73, and the two positioning projections 73 are arranged inside the edge of the connecting portion 2 and form mutual limitation with the edge of the connecting portion 2. Further still, a positioning strip 221 is provided on the side of the limiting portion 22 close to the flat mop rod 7, and the positioning strip 221 cooperates with the positioning projection 73 for mutual limitation, thereby preventing the wringing sleeve from rotating.

[0061] In the embodiment, the wringing head 1 includes an upper extrusion frame 4 and a lower extrusion frame 5. The upper extrusion frame 4 and the lower extrusion frame 5 are fixed together, and a wringing opening 11 is formed between the upper extrusion frame 4 and the lower extrusion frame 5. The extrusion mechanism includes a scraping blade 41 and a roller 42. The scraping blade 41 and the roller 42 are rotatably arranged on the upper extrusion frame 4. A roller bracket 51 is provided on the lower extrusion frame 5, and rollers 52 are installed on the roller bracket 51, preferably 2 rollers 52 are installed. The rollers 52 and the extrusion mechanism are arranged oppositely, and the flat mop plate reciprocates between the rollers 52 and the extrusion mechanism. The rotation direction of the rollers 52 is the same as the movement direction of the mop plate 8. Thus, when the mop plate 8 moves through the wringing opening 11, the scraping blade 41 scrapes and cleans the wiping material on the mop plate, and the roller 42 squeezes the wiping material for dehydration. The rollers 52 support the smooth back-and-forth movement of the mop plate in the wringing opening. Further, 3 groups of rollers 42 are provided on the upper extrusion frame 4 for multiple water squeezing. And a long hole 43 corresponding to the roller 42 is provided on the upper extrusion frame 4, and the long hole 43 facilitates the cleaning of the dirt attached to the roller 43. Further, a first limiting piece 44 and a second limiting piece 45 are also provided on the upper extrusion frame 4. The scraping blade 41 is rotatably arranged between the first limiting piece 44 and the second limiting piece 45. When the mop plate 8 passes through the wringing opening 11, it drives the scraping blade 41 to rotate backward, and then the scraping blade 41 abuts against the first limiting piece 44. At this time, the width of the wringing opening 11 is the smallest, and the scraping force on the wiping material is the greatest, that is, it is very convenient to clean the garbage on the wiping material; when the mop plate 8 moves back and disengages from the wringing opening 11, the scraping blade 41 rotates with the mop plate 8 and then tilts downward to abut against the second limiting piece 45, increasing the space of the wringing opening 11 to facilitate the passage of the mop plate 8.

[0062] In a preferred embodiment, a chuck 74 is further included. The chuck 74 can pick up the garbage on the wiper for preliminary cleaning, or pick up the collected garbage and place it into the trash can. The chuck 74 is received at one end of the mop rod 7 away from the mop plate 8. A receiving groove 71 is provided on the mop rod 7, and a clamping edge 72 is provided on the inner side wall near the opening end of the receiving groove 71. A clamping strip 75 is provided on the chuck 74 and is engaged with the clamping edge 72. Insert the chuck 74 into the receiving groove 71 and press it so that the clamping strip 75 passes through the clamping edge 72 to receive the chuck 42 in the mop rod 7. When in use, hold the end of the chuck 74 and pull it outwards to take out the chuck.

[0063] In the above technical solution, when it is necessary to clean the mop plate 8, hold the handle 3 with one hand, and at the same time press the unlocking portion 612 with the thumb to unlock the sleeve. Then, hold the handle 3 and drive the sleeve to slide up and down along the mop rod 7. Further, the mop plate 8 moves back and forth in the scraping opening 11, and the squeezing mechanism squeezes and cleans the wiper. When the cleaning of the wiper on the mop plate is completed, when the hand leaves the handle 3, press the locking portion 611 with the thumb by the way, so that the clamping plate 62 rotates into the lock hole and protrudes from the inner wall of the handle 3 to fix the sleeve on the mop plate. After cleaning the ground, the wiper is attached with garbage such as hair. The chuck can be pulled out from the end of the mop rod to preliminarily clean the hair and other garbage on the wiper, avoiding it from being wound around the scraping blade or the roller later and affecting the cleaning effect of the sleeve, or pick up the garbage cleaned on the ground and put it into the trash can. After the cleaning is completed, the chuck is received in the receiving groove.

[0064] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, the technical solutions without substantial transformation are still within the protection scope.
