Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, in particular to a hands-free flat mop. Background Art

[0002] Flat mops are a common floor cleaning tool. Their flat mop structure has the characteristics of effective mopping of a large floor area and high mopping efficiency. At the same time, their cost is relatively low, and they are widely used in cleaning work. In addition, the convenience of existing cleaning tools is an important aspect. For example, the hands-free washing and squeezing cleaning structure has become the standard configuration of general manual mops. Therefore, like traditional mops, flat mops need to be cleaned and squeezed from time to time during the mopping process to ensure the mopping effect. The existing flat mop either uses a special squeezing bucket to squeeze water, or has its own squeezing head structure. In the existing flat mop structure with its own squeezing head structure, the squeezing member in the head structure is mostly a squeezing roller with a fixed position or a variable position. On the one hand, the squeezing force is small and the squeezing efficiency is low. On the other hand, due to the unreasonable design of the squeezing structure, the flat mop splashes a lot of water when squeezing water. If a special matching squeezing bucket is not used, a larger bucket basin is required to receive the water. Otherwise, the water is likely to splash onto the ground when squeezing water, making it dirty and messy, and even requiring rework from time to time, affecting the mopping efficiency.

DETAILED DESCRIPTION

[0022] Example:

[0023] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Referring to the accompanying drawings, a hands-free flat mop includes a flat mop base plate 1, a mop rod 2 and a stroking head body 3. The stroking head body 3 is slidably mounted on the mop rod 2 and is provided with a stroking opening for the flat mop base plate 1 to pass through and squeeze water. The stroking opening is provided with an elastic water squeezing member 4. The elastic water squeezing member 4 includes an elastic water squeezing scraper 41 extending from the inner wall of the stroking opening to the middle of the stroking opening, and a water squeezing gap is formed between the front end of the elastic water squeezing scraper 41 and the inner side surface opposite to the stroking head body 3. The elastic water squeezing scraper 41 is provided with a spring squeegee 41. 1 can be elastically deformed along the sliding squeezing direction of the stroker body 3; the stroker body 3 is provided with squeezing grooves 33 on the left and right sides of the inner side, the elastic squeezing member 4 is slidably arranged on the squeezing grooves 33, the squeezing grooves 33 are inclined, when the elastic squeezing member 4 is located at the lower end of the squeezing groove 33, the width of the squeezing gap is relatively large, when the elastic squeezing member 4 is located at the higher end of the squeezing groove 33, the width of the squeezing gap is relatively small.

[0026] The elastic water squeezing member 4 includes a base 42, and the elastic water squeezing member 4 is slidably installed in the water squeezing chute 33 through the two sides of the base 42. Referring to the drawings, the stroker body 3 includes a first stroker body 31 and a second stroker body 32 that are mutually clamped and fixed to form a stroker structure, the first stroker body 31 is U-shaped, the two side walls of the first stroker body 31 are provided with the water squeezing chute 33 near the opening end, and the second stroker body 32 is detachably fixedly installed at the opening of the first stroker body 31. During assembly, the elastic water squeezing member 4 is first installed into the squeezing groove 33 of the first mopping head body 31, and then the second mopping head body 32 is used to clamp and cover the opening of the first mopping head body 31, and the elastic water squeezing member 4 is restricted to slide back and forth in the squeezing groove 33, and then the assembled mopping head is mounted on the front end of the mop rod 2, so that the elastic water squeezing blade 41 forms a squeezing gap with a variable width relative to the other side of the mopping head. When the flat mopping base plate 1 passes through the mopping head from bottom to top, due to the opposite movement of the flat mopping base plate 1 and the elastic water squeezing member 4, under the action of the friction between the two, the mopping cloth of the flat mopping base plate 1 will bring the elastic water squeezing member 4 to the upper part of the mopping head (that is, the elastic water squeezing member 4 is located at the high end of the squeezing groove 33). At this time, the squeezing gap width formed by the elastic water squeezing blade 41 and the inner side of the mopping head body 3 is relatively small, and the elastic water squeezing blade 41 has a greater squeezing effect on the mop cloth, which will be mopped. A large amount of dirty water in the cloth is squeezed out. On the contrary, when the flat mop base plate 1 passes through the mopping head from top to bottom, the mop will bring the elastic water squeezing part 4 to the lower part of the mopping head (that is, the elastic water squeezing part 4 is located at the high end of the water squeezing slot 33). At this time, the width of the water squeezing gap formed by the elastic water squeezing scraper 41 and the inner side of the mopping head body 3 is relatively large, and the elastic water squeezing scraper 41 has a weak water squeezing effect on the mop, basically no dirty water is squeezed out, and the downward pushing action of the flat mop base plate 1 is more labor-saving. Therefore, the water squeezing of the flat mop of this embodiment mainly relies on the squeezing of water by the elastic water squeezing scraper 41 when the flat mop base plate 1 is lifted up and passes through the stroke head body 3. Although the amount of water squeezed is large at this time, the water squeezing point is located at the lower part of the stroke head body 3. Under the shielding and drainage effect around the stroke head body 3, it will not cause too much water splashing. In the process of squeezing water when the flat mop base plate 1 is pushed down and passes through the stroke head body 3, due to the large water squeezing gap and the small amount of water squeezed, although the water squeezing point is located at the upper part of the stroke head body 3 and lacks the shielding of the stroke head body 3, it will basically not cause water splashing, thereby completely avoiding the problem that the elastic water squeezing of the flat mop easily causes excessive water splashing.

[0027] Referring to the accompanying drawings, this embodiment mainly utilizes the relative movement between the mop and the elastic water squeezing blade 41 to make the elastic water squeezing blade 41 move and deform, thereby more effectively achieving the water squeezing effect on the mop. The elastic water squeezing blade 41 extends from the base 42 to the middle of the raking opening, and a gap is reserved between the front end and the inner wall of the raking opening on the opposite side of the base 42, so that the flat mop substrate 1 can pass through and squeeze water. It can be understood that the reserved gap can be passed by the flat mop substrate 1 and the width is smaller than the width of the flat mop substrate 1, so that the elastic water squeezing blade 41 can squeeze water from the mop on the flat mop substrate 1. In this embodiment, the inclined squeezing chute 33 is used to change the width of the squeezing gap when the flat mop substrate 1 is lifted and pushed down. In a specific product of the present invention, the inclination of the squeezing chute 33 is 5 degrees, and the squeezing gap width change value caused by the elastic squeezing member 4 being located at the upper and lower ends of the squeezing chute 33 is 5 mm, which has a good squeezing feel and a better squeezing effect in practical applications.

[0028] In the present embodiment, the height of the elastic water squeezing scraper 41 increases from low to high from the front row to the back row, that is, the elastic water squeezing scraper 41 in the front row has the lowest height and the largest water squeezing gap, and the elastic water squeezing scraper 41 in the back row has the highest height and the smallest water squeezing gap. In the present embodiment, the height difference between the front and rear rows of elastic water squeezing scraper 41 is 0.35 mm. This design can make the mop head feel better during the water squeezing process and have a better water squeezing effect. At the same time, it can achieve the effect of better protecting the mop wool, slowing down the loss of the mop, and ensuring its service life.

[0029] Referring to the attached drawings, the elastic water squeezing blades 41 of this embodiment are arranged in two rows, the front row is a continuous long blade, which continuously extends from one side of the base 42 to the other side; the rear row of the elastic water squeezing blades 41 is a plurality of elastic water squeezing blades 41 arranged at intervals, and the adjacently arranged elastic water squeezing blades 41 form a water leakage channel on one or both sides. When the flat mopping base plate 1 squeezes water from bottom to top, the dirty water falls directly from the bottom of the elastic water squeezing blades 41, and when the flat mopping base plate 1 squeezes water from top to bottom, the dirty water reaches the bottom of the elastic water squeezing blades 41 through the water leakage channel and falls. Corresponding to the elastic water squeezing member 4 in this embodiment, the first stroke body 31 and the second stroke body 32 in the stroke body 3 are both provided with a leakage hole 34. The leakage hole 34 on the second stroke body 32 is located at the lower part thereof, that is, the front part of the stroke body 3. A large amount of dirty water generated when the stroke body 3 is lifted up to squeeze water is diverted out from the front end of the stroke body 3 to reduce water splashing. The lower part of the first stroke body 31 is also provided with a leakage hole 34, and its function is the same as that of the leakage hole 34 on the first stroke body 31. The purpose of providing the leakage holes 34 on the first stroke body 31 and the second stroke body 32 is to make it more convenient for users to use. Whether the user squeezes water with a positive grip (mop surface facing down) or a reverse grip (mop surface facing up), the stroke body 3 can divert water through the leakage hole 34.

[0030] The front end of the elastic water squeezing scraper 41 includes an arc section, and the arc direction extends from the upper end to the lower end of the mop rod 2. Since the structural design of the arc section has a downward guiding effect, the elastic water squeezing scraper 41 exerts different squeezing forces on the flat mop base plate 1 when the flat mop base plate 1 moves back and forth through the scoop mouth to squeeze water. In the process of the flat mop base plate 1 pushing down to squeeze water from top to bottom, on the one hand, the elastic water squeezing member 4 slides down, and the squeezing gap becomes larger, and on the other hand, the relative movement direction is consistent with the direction of the arc section, so the squeezing force is relatively small, which is a labor-saving micro squeezing process; on the contrary, in the process of the flat mop base plate 1 lifting up to squeeze water from bottom to top, on the one hand, the elastic water squeezing member 4 moves up, and the squeezing gap becomes smaller, and on the other hand, the relative movement direction is opposite to the direction of the arc section, so the squeezing force is relatively large, which is a forceful squeezing process, squeezing out a large amount of dirty water in the mop. It should be noted that the mop cloth in the existing flat mop base plate 1 is mostly in the form of snap-on bonding, and the outer edge of the mop cloth is a rimmed structure with a relatively high hardness. In addition, the flat mop base plate 1 may also be slightly deformed due to long-term use or improper placement, resulting in inaccurate alignment between the flat mop base plate 1 and the stroking mouth of the stroking head body 3, and the squeezing process is likely to cause the elastic squeezing scraper 41 to be stuck or hit, greatly affecting the service life of the elastic squeezing member 4. For this reason, in this embodiment, a number of guide bones 45 are added in front of the front row of elastic squeezing scrapers 41, and the guiding direction of the guide bones 45 is opposite to the curvature direction of the arc segment, that is, from the lower end of the mop rod 2 to the upper end, so that the flat mop base plate 1 can be well guided to pass through the stroking head body 3 during the lifting process, avoiding the flat mop base plate 1 from being stuck or hitting the elastic squeezing scraper 41, and extending the service life of the elastic squeezing member 4; this problem does not exist during the pushing down process of the flat base support plate due to the guiding effect of the arc segment.

[0031] In some other embodiments, in order to further increase the service life of the elastic water squeezing member 4, the elastic water squeezing scraper 41 thereon is arranged to be an inclined structure, which is inclined from both sides to the middle and from top to bottom, and forms a certain angle with the upper end surface of the flat drag substrate 1. During the process of the two moving toward each other, the interaction force has a gradual process, which can effectively reduce the impact force of the flat drag substrate 1 on the elastic water squeezing scraper 41 and reduce the damage rate of the elastic water squeezing scraper 41.

[0032] Referring to the accompanying drawings, elastic gaps for increasing the elastic deformation of the elastic water squeezing scraper blade 41 are opened on both sides of the rear end thereof. According to the design of the size and shape of the elastic gaps, such as the U-shaped gap 46 shown in the accompanying drawings, the deformation and deformation force of the elastic water squeezing scraper blade 41 can be designed to be of a suitable size so as to be suitable for different models and materials.

[0033] Referring to the attached drawings, a rear baffle 43 is provided behind the rear end of the elastic water squeezing scraper 41. The elastic water squeezing scraper 41 does not contact the rear baffle 43 in a non-deformed state. When the flat-towed base plate 1 squeezes water from top to bottom, due to the guiding effect of the arc-shaped section at the front end of the elastic water squeezing scraper 41, its deformation resistance is small and the deformation amount is small. On the contrary, when squeezing water from bottom to top, the movement direction of the flat-towed base plate 1 is opposite to the bending direction of the arc-shaped section, and the deformation resistance is large. The rear baffle 43 located behind the base of the elastic water squeezing scraper 41 can contact each other when it is deformed to a certain extent, thereby preventing the elastic water squeezing scraper 41 from deforming too much and reducing the occurrence of the elastic water squeezing scraper 41 breaking. The rear baffle 43 in this embodiment is a long column placed horizontally behind the base of the elastic water squeezing scraper 41.

[0034] Referring to the accompanying drawings, the elastic water squeezing scraper 41 can be provided with a plurality of scraping teeth 44, and the scraping teeth 44 are arranged at intervals. When the flat mopping base plate 1 squeezes water from bottom to top, the scraping teeth 44 can effectively scrape off the hair, paper scraps and other debris on the mop.

[0035] The above only describes the preferred embodiments of the present invention, but it cannot be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
