Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, in particular to a cleaning structure and a flat mop and a mop bucket. Background Art

[0002] Flat mops are chosen and used by more and more people for their advantages such as being economical, practical, convenient and quick to use. The existing flat mops have roughly similar structures, including a mop rod and a flat mop head. The mop rod is hinged on the upper surface of the flat mop head, and a wipe is installed on the back of the flat mop head. In order to clean the wipe after use, the flat mop is also equipped with a cleaning mechanism. In order to better clean the wipe, the existing cleaning mechanism will be provided with a liquid filling tank for adding cleaning liquid on the cleaning mechanism of the mop plate. The cleaning liquid slowly seeps out from the liquid seepage port or liquid outlet of the liquid filling tank and flows onto the wipe to deeply clean the wipe. However, the cleaning liquid has a strong fluidity and may flow away before it is completely in contact with the wipe for cleaning. At the same time, it also flows unevenly to the surface of the entire wipe, and there is a situation where there is too much cleaning liquid on some surfaces of the wipe, while there is no cleaning liquid on other surfaces. Another cleaning mechanism is provided with a storage bin, in which a bactericidal slow-release block is arranged. When the bactericidal slow-release block contacts water, the bactericidal cleaning components are diluted for sterilization and cleaning. However, the bactericidal cleaning components are easily flowed away with the water and have less contact with the wipes, resulting in poor cleaning effect. Summary of the invention

DETAILED DESCRIPTION

[0041] The present invention will be further described below in conjunction with the accompanying drawings:

[0042] like Figures 1 to 12 As shown, a cleaning structure includes a water squeezing rack, a through hole for a flat mop head to pass through is provided on the water squeezing rack, a scraping assembly 2 is provided on one side of the through hole, a supporting assembly 3 is provided on the side of the through hole opposite to the scraping assembly 2, a cleaning opening 4 is formed between the scraping assembly 2 and the supporting assembly 3, a flat mop head 20 moves back and forth in the cleaning opening 4, the supporting assembly 3 supports the mop head 20 to contact with the scraping assembly 2, and the scraping assembly 2 cleans the wiped material on the flat mop head 20. A receiving cavity 5 communicating with the cleaning opening 4 is also provided on the water squeezing rack, a solid cleaning block 8 is fixed in the receiving cavity 5, the cleaning block 8 is preferably solid soap, and the length and width of the cleaning block 8 match the size of the receiving cavity 5. A cleaning roller 7 is provided on the opening between the accommodating chamber 5 and the cleaning mouth 4. The cleaning roller 7 is rotatably arranged on the squeezing rack. The cleaning roller 7 is in contact with the wiping material and the cleaning block 8 of the mop head 20 respectively. When the mop head 20 moves back and forth in the mouth, the cleaning roller 7 rotates accordingly, so that the cleaning roller 7 rubs the adhered cleaning block 8 onto the wiping material of the flat mop head 20, and the cleaning block 8 can deeply clean the wiping material. Further, the accommodating chamber 5, the cleaning roller 7 and the scraping assembly 2 all extend the entire length of the cleaning mouth 4, so that they can completely contact the wiping material laterally, and the cleaning roller 7 can rub the cleaning block 8 onto the entire wiping material more evenly; further, a plurality of arc protrusions 73 are staggered on the surface of the cleaning roller 7, and the arc protrusions 73 have the effect of scrubbing the wiping material so that the cleaning is more thorough, and at the same time, the arc protrusions 73 can more conveniently transfer the cleaning block 8 to the wiping material.

[0043] In a preferred case, when the flat mop head 20 moves upward in the cleaning groove 4, it drives the cleaning roller 7 to rotate in the water squeezing frame, and when the flat mop head 20 moves downward in the cleaning groove 4, the cleaning roller 7 is fixed relative to the water squeezing frame; or when the flat mop head 20 moves downward in the cleaning groove 4, it drives the cleaning roller 7 to rotate in the water squeezing frame, and when the flat mop head 20 moves upward in the cleaning groove 4, the cleaning roller 7 is fixed relative to the water squeezing frame, that is, the cleaning roller 7 rotates unidirectionally in the water squeezing frame, so that the contact and friction direction with the cleaning block 8 is always consistent, so that the state of the cleaning block 8 will not change, thereby avoiding excessive wear of the cleaning block 8.

[0044] A rotating shaft 71 is provided at both ends of the cleaning roller 7. The rotating shaft 71 is formed by a plurality of radially intersecting spokes 72.

When the rotating shaft 71 is on the side without the limit block 131, the rotating shaft 71 can rotate in the axial hole 13. When the rotating shaft 71 moves to the side of the limit block 131 following the flat mop head, the limit block 131 will be stuck between two adjacent spokes 72 of the rotating shaft 13 to prevent the rotating shaft 71 from rotating.

[0045] In a preferred case, a cover 6 is provided on one side of the accommodating chamber 5, and opening the cover 6 can facilitate replacement or placement of the cleaning block 8. The cover 6 can be provided on any side wall of the accommodating chamber 5, and can be a side wall opposite to the cleaning roller 7, or a side wall adjacent to the cleaning roller 7. One side of the cover 6 is rotatably connected to the water squeezing rack, and a U-shaped clip 62 is provided on the other side of the cover 6, a clamping protrusion 63 is provided on the U-shaped clip 62, and a clamping groove 14 corresponding to the U-shaped clip 62 is provided on the water squeezing rack; when the clamping protrusion 63 is clamped in the clamping groove 14, the cover 6 is in a closed state, and the cover 6 can be opened by pressing and compressing the U-shaped clip 62 so that the clamping protrusion protrudes from the clamping groove 14.

[0046] In a preferred case, an elastic member 51 is provided in the accommodating chamber 5, and the elastic member 51 is placed on the bottom side of the cleaning block 8 to support the cleaning block 8 to maintain connection with the cleaning roller 7. The elastic member 51 is in a compressed state, and as the volume of the cleaning block 8 decreases, the elastic potential energy is released to push the cleaning block 8 upward, so that it maintains contact and connection with the cleaning roller 8. In one embodiment, for example, the elastic member 51 includes a deformable spring and a support plate, one end of the deformable spring is connected to the support plate and the other end is connected to the side wall of the accommodating chamber 5, and the support plate is supported at the bottom of the cleaning block.

[0047] In this embodiment, the elastic member 51 includes two fixing plates 53, and an arc-shaped bow plate 52 is connected between the two fixing plates 53. The bow plate 52 is in contact with the cleaning block 8 and the fixing plate 53 is pressed against the side wall of the accommodating chamber 5. When the bow plate 52 is compressed, the two fixing plates 53 move away from each other, and when the bow plate 52 is arched, the two fixing plates 53 move closer to each other. In another embodiment, a bow plate 52 tilted upward is connected to each fixing plate 53, and the two bow plates 52 are arranged in the accommodating chamber relative to each other, and the fixing plate 63 is fixedly connected to the cover 6; further, when the cover 6 is arranged on the opposite side of the cleaning roller 7, a positioning groove 61 is provided on the cover 6, and a pressing plate 64 is provided on the upper side of the positioning groove 61. The fixing plate 52 is placed in the positioning groove 61 and inserted into the lower side of the pressing plate 64, so as to ensure that the fixing plate 53 is fixed in the positioning groove 61.

[0048] In a preferred case, a disengagement component is also provided in the accommodating chamber 5, and the disengagement component is movably arranged on the water squeezing rack and the retraction component can drive the cleaning block 8 to separate from the cleaning roller 7. The disengagement component is a pressure strip arranged on the upper side of the cleaning portion 8, and an arc-shaped groove is provided on the water squeezing rack. The two ends of the pressure strip slide in the arc-shaped groove, and when the pressure strip slides to one side of the arc-shaped groove, it is just between the cleaning roller 7 and the cleaning block 8, so that the cleaning roller 7 and the cleaning block 8, when the pressure strip slides to the other side of the arc-shaped groove, escape from between the cleaning roller 7 and the cleaning block 8 and slide to one side of the cleaning block 8; or the disengagement component is connected to the cleaning block 8, and can drive the cleaning block 8 to compress the support component 8, so that the cleaning block 8 is disengaged from the cleaning roller 7. At this time, the disengagement component is snap-connected or screwed to the water squeezing rack, and can drive the cleaning block 8 to disengage from or contact the cleaning roller 7.

[0049] In a preferred case, the scraping assembly 2 includes a scraper 21, which is movably arranged on the water squeezing frame; a slide 15 is arranged on the water squeezing frame, and the slide 15 is inclined to the side away from the accommodating chamber 5, and sliders 55 are arranged at both ends of the scraper 51, and the sliders 55 can slide in the slide 15. When the mop head 20 moves upward on the cleaning mouth, it drives the scraper 21 to move upward along the slide 15, at which time the width of the cleaning mouth 4 is the smallest, and the squeezing force on the wipe is relatively large; when the mop head 20 moves downward on the cleaning mouth, it drives the scraper 21 to move downward along the slide 15, at which time the width of the cleaning mouth 4 is the largest, and the squeezing force on the wipe is relatively small. In this embodiment, the limit block 131 is arranged on the side of the shaft hole 13 away from the scraper 21, when the width of the cleaning mouth 4 is the smallest, the cleaning roller 7 is relatively fixed, and when the width of the cleaning mouth 4 becomes larger, the cleaning roller 7 rotates relatively. This can avoid the waste of cleaning material when the mop head 20 is slightly lifted and cannot fully contact the cleaning roller 7.

[0050] The scraping assembly 2 further includes scraping teeth 23, which are arranged at the front side of the scraper 21. A guide roller 9 is arranged between the scraping teeth 23 and the scraper 21. The scraping teeth 23 first scrape and clean the hair and other garbage on the wiped object to avoid winding around the guide roller 9 or the cleaning roller 7. Furthermore, the scraping teeth 23 are arranged at the inlet side of the cleaning squeegee 4 and are integrally formed with the water squeezing frame.

[0051] In a preferred case, the squeezing rack includes an upper bracket 11 and a lower bracket 12, and the upper bracket 11 is connected to the lower bracket 12 by snap-fitting or screwing; and a through hole is formed between the upper bracket 11 and the lower bracket 12. The scraper teeth 23, the guide roller 9 and the cleaning roller 7 are arranged on the lower bracket 12 in sequence, and the accommodating chamber 5 is arranged on the lower side of the cleaning roller 7.

A slot 17 that cooperates with the pivot 32 is arranged on the support seat 16, and the roller 31 is rotatably arranged in the slot 17, and the roller 31 can rotate following the movement of the flat mop.

[0052] A flat mop includes a mop rod 10 and a mop head 20 rotatably connected to the mop rod 10, a wiping object (not shown in the drawings) is arranged on the mop head 20, a stroking sleeve 30 is arranged on the mop rod 10, the stroking sleeve 30 includes a sleeve rod 301 and a shell 302, the shell 302 is connected to one end of the sleeve rod 31, and the sleeve rod 301 is sleeved on the mop rod 10, and the cleaning structure described in the above technical solution is arranged in the shell 302, the stroking sleeve 30 can move up and down along the mop rod 10, so that the mop head 20 moves up and down in the cleaning stroking mouth 4 to clean the wiping object. Furthermore, a track is provided in the sleeve rod 301, and a limit groove 304 is provided at the end of the track. A slider is fixedly connected to the mop rod 10. When the sleeve 30 moves up and down along the mop rod 10, the slider slides in the track; when cleaning is completed and the sleeve 30 needs to be fixed to the mop rod 10, the slider is stuck in the limit groove 304.

[0053] A mop bucket comprises a bucket body, a bucket cover is arranged on the bucket body, and the bucket cover is provided with the cleaning structure described in the above technical solution.

[0054] In the above technical solution, when it is necessary to clean the flat mop head, the mop head is inserted into the cleaning stroke and moves back and forth. The scraping assembly and the cleaning roller are driven by the flat mop head to move. At this time, the scraping assembly scrapes away the dirt and garbage on the wiped object, and at the same time, the cleaning roller rubs the cleaning body on the wiped object, and the protrusions on the cleaning roller 7 scrub the wiped object, thereby achieving deep cleaning of the wiped object and better cleaning effect on the flat mop.
