[0001] Flat Mop Bucket with Wringer

[0002] DESCRIPTION

[0003] The invention relates to devices for cleaning and washing, namely to buckets with devices for wringing out a flat mop [A47L 13 / 00, A47L 13 / 10, A47L 13 / 14, A47L 13 / 16, A47L 13 / 20, A47L 13 / 24, A47L 13 / 26, A47L 13 / 58, A47L 13 / 59, A47L 13 / 60, A47L 13 / 022 A47L 13 / 144, A47L 13 / 146, A47L 13 / 252, A47L 13 / 253, A47L 13 / 254].

[0004] Various devices for cleaning and washing are widely known from the prior art, in which various wringing units are implemented, including flat mops.

[0005] For example, a TOOL FOR CLEANING A FLAT MOP is known [CN 213850549 U, published: 03.08.2021], includes a mop bucket and a flat mop, the flat mop includes a mop rod and a flat mop head movably connected to the mop rod, the mop bucket is characterized in that a bucket lid is provided on the mop bucket, an opening is provided on the bucket lid, and a water storage tank is provided in the bucket, a scraper is longitudinally horizontally mounted on the side wall of the opening, the front side and the rear side of the upper surface of the scraper are respectively provided with a first positioning recess and a second positioning recess, the flat mop head is movably provided with a pressure plate, and the front end of the pressure plate and the rear end, respectively provided with a first and a second connecting part, one end of the first connecting part away from the pressure plate is provided with a first sliding part,and one end of the second connecting part away from the pressure plate is provided with a second sliding portion, the first sliding portion is slidably connected to the first positioning recess through the first roller, and the second sliding portion is slidably connected to the second positioning recess through the second roller, in the recess the pressure plate slides along the length direction of the flat head of the mop through the interaction of the first sliding portion and the first positioning recess and the interaction of the second sliding portion and the second positioning recess.

[0006] The disadvantage of this analogue is its low efficiency, due to the fact that it contains only one compartment in which the mop is washed and wrung out simultaneously, which leads to rapid contamination of the water and requires its replacement. Also known from the prior art is a SQUEEZE FLAT MOP CLEANING TOOL [US 11337578 B2, published: 05 / 24 / 2022], comprising a mop bucket and a flat mop, wherein the flat mop comprises a mop stick and a flat mop head movably connected to the mop stick, the mop bucket has a wringing zone, a wringing device is mounted on the bucket, comprising a scraper plate used to wring out the mop and a support element located opposite the scraper plate, and the wringing hole is formed between the scraper plate and the support element, wherein during wringing the flat mop head is inserted into the wringing hole in the wringing zone, the scraper plate touches the mop when the mop moves relative to the scraper the mop plates are wrung out,wherein the scraper plate is mounted on the mop bucket with the possibility of rotation, and the size of the opening for the mop is variable upon rotation of the scraper plate, wherein when the flat head of the mop is fed downward, the scraper plate rotates downward, so that the scraper plate is located in a narrow position relative to the support member, thereby reducing the squeezing opening and increasing the frictional force acting on the mop to facilitate squeezing and scraping the mop, and when the flat head of the mop is fed upward, the scraper plate rotates upward, thereby increasing the squeezing opening and reducing the frictional force between the scraper plate and the mop, wherein the scraper plate is mounted directly on the bucket,

[0007] The disadvantage of the analogue is its low reliability, caused, firstly, by the complexity of the design of the wringing device, and secondly, by the orthogonal arrangement of the force acting on the scraper plate from the spring and the force acting on the scraper plate from the mop, which increases the likelihood of damage to the scraper plate compared to if these forces were directed to each other at an angle.

[0008] The closest in technical essence is a BUCKET WITH A WRINGER FOR A FLAT MOP [CN 217338478 U, published: 09 / 02 / 2022], including a bucket body and a bucket lid, the bucket body is provided with a cleaning compartment, the bucket lid is provided with an opening for wringing above the corresponding cleaning compartment, the bucket lid at the opening for wringing is provided with a scraper for wringing out the mop during the movement of the flat mop up and down along the cleaning compartment and the interaction of the scraper with it, wherein the scraper is made in the form of a plate that passes into the collection cavity, forming a drainage channel and the water collected from the mop during wringing enters the collection cavity, the scraper is detachably connected to the upper part of the bucket lid with the possibility of dismantling it from above.

[0009] The main technical problem of the prototype is the low efficiency of wringing out the mop, caused by the lack of constant pressure on the mop from the scraper, as well as the low reliability of the scraper, lid and bucket as a whole, caused by the absence in the design of the scraper fastening of damping (absorbing) excessive, directed tangential force impact from the interacting surface of the mop, as a result of which the fastening elements on the scraper and the attachment points of the scraper in the lid are destroyed and, as a consequence, further use of the bucket as a wringing tool loses meaning and for its restoration it is necessary to replace not only the scraper, but also the lid, which is very difficult due to the lack of spare parts at the points of sale of buckets and in this case the bucket as a whole is subject to replacement.However, the problem of increasing reliability cannot be solved by strengthening the fastening elements and fastening points, since this will increase the force acting on the mop, which will lead to rapid wear of the cleaning material of the mop and will require its rapid replacement.

[0010] The objective of the invention is to eliminate the shortcomings of analogues and the prototype in terms of wringing efficiency and the service life of the bucket and mop.

[0011] The technical result of the invention is the creation of a structurally reliable bucket with a wringer for a flat mop, the wringing part of which optimally adapts to the surface of a flat mop, ensures effective wringing of the mop, but at the same time has a gentle effect on the mop

[0012] The said technical result is achieved by a bucket with a wringer for a flat mop, comprising a container and a lid coupled to the container with the ability to cover the container from above. The container has compartments for washing the mop and for wringing the mop, which are isolated from each other by means of a partition, and openings are formed in the lid of the bucket for the passage of the mop into one or the other of the compartments. At least one scraper is mounted to the lid of the bucket from below, along the opening above the wringing compartment, in a manner that is pivotally movable following the vertical movement of the mop. The hinged connection of the scraper to the lid of the bucket is spring-loaded, allowing for the scraper to continuously adapt to the surface of the flat mop. In particular, the lid is removable.

[0013] In particular, the scrapers are made in the form of horizontally oriented strips with stiffening ribs in the lower part.

[0014] In particular, when installing several scrapers, the said scrapers are mounted one above the other in one vertical row.

[0015] In particular, the spring-loaded mounting of the scraper is carried out using a reciprocating spring mounted to one or both end cylindrical hinges of the scraper.

[0016] In particular, the spring-loaded mounting of the scraper is achieved using a compression spring mounted between the rear edge of the scraper and the cover.

[0017] In particular, the front edge of the scraper that interacts with the cleaning surface of the mop is made pointed and beveled downwards.

[0018] In particular, rollers are mounted in the lid, with their outer surface facing the side of the mop opposite the cleaning surface, with the possibility of interaction of the rollers with the said surface of the mop, creating guides and facilitating the sliding of the mop in the openings of the lid.

[0019] In particular, the container compartments in the lower part are equipped with drain holes, closed with removable lids.

[0020] In particular, the container is equipped with a folding handle.

[0021] In particular, the lid is equipped with a folding handle.

[0022] In particular, the rear side of the scraper can be made rounded, and in the niche of the lid along the rear side of the scraper, upwardly protruding guides can be mounted with the possibility of providing a sliding support for the scraper.

[0029] Implementation of the invention.

[0030] The invention is a bucket containing a container 1 with a lid 2 (see Fig. 1).

[0031] The container 1 and the lid 2 in the plan can be made in any shape, but corresponding to each other in shape and size with the possibility of connecting the lid 2 with the container 1.

[0032] In one embodiment, the tank 1 is rectangular in plan (horizontal cross-section) with rounded corners (see Fig. 2). Accordingly, in vertical longitudinal section, the tank 1 may be rectangular or shaped like an inverted trapezoid with its small base pointing downwards.

[0033] Container 1 contains two vertical, sealed compartments, one of which is designed for wetting and washing the mop, and the other for wringing it out. The compartments can be isolated from each other by a single vertical partition, or one compartment can be placed within the other, as shown in Fig. 1. The compartments are designed to allow mop washing in one compartment and mop wringing in the other.

[0034] Cover 2 is removable.

[0035] In the cover 2 above the isolated compartments, which are mentioned above, there are openings for the passage of a mop through them, mainly in a T-shape for a folding flat mop, in which the flat base is hingedly mounted on the handle with the possibility of rotation and placement both across the handle and along it (see Fig. 2).

[0036] Along the perimeter of cover 2 and above the insulating partition in cover 2, grooves are formed at the bottom that can interact with the upper edge of container 1 and the partition (see Fig. 1). Cover 2 is designed to be positioned on the upper edge of container 1 over its outer side walls.

[0037] Beneath the opening in cover 2, above the compartment of container 1, designed for wringing out the mop, a niche is formed by vertically extending side walls. In said niche, along the side toward which the mop's working cleaning surface faces when it is placed within said compartment, scrapers 3 (see Fig. 1) are mounted, rotating vertically along the rear edge and designed to interact with the mop's cleaning surface.

[0038] Scrapers 3 are made in the form of horizontally oriented strips with stiffening ribs in the lower part and with cylindrical hinges at the ends, made with the possibility of placement in openings made in the opposite side walls of the niche of the opening for squeezing the mop of the cover 2.

[0039] At least the lower scraper 3 is made spring-loaded, for example, with the help of a reciprocating (ring) spring mounted to one or both end cylindrical hinges of the scraper 3. In one embodiment, the lower scraper 3 is made spring-loaded with the help of a compression spring mounted between the rear edge of the scraper, for example, with the help of a vertically oriented spike (see Fig. 5) and the cover 2. Such a spring-loaded or elastic mounting of the scraper 3 is designed with the possibility of increasing the force of action of the lower scraper 3 on the washing surface of the mop and improving the removal of moisture (spinning) from the sorbent material of the mop.

[0040] The front edge of the scrapers 3, which interacts with the cleaning surface of the mop, is made pointed and beveled downwards.

[0041] The rear side of scraper 3 can be rounded, and upward-protruding guides can be mounted in the recess of lid 2 along this rear side of scraper 3. The rear side of scraper 3 rests on these guides and slides along the guides. This design ensures a secure attachment of scraper 3 in the lid, ensuring its retention under excessive force from the mop.

[0042] Under the openings in the cover 2, rollers 4 are mounted, with their outer surface facing the side of the mop opposite the washing surface, with the possibility of interaction of the rollers with the said surface of the mop, creating guides and facilitating the sliding of the mop in the openings of the cover 2, including the possibility of increasing the reliability of the bucket and the mop.

[0043] The compartments of the container 1 in the lower part can be provided with drain holes, closed with removable covers (not shown in the figures).

[0044] The container 1 is provided with a handle made in a U-shape, repeating the shape of the container 1 when viewed from above, wherein the handle is mounted to the container 1 pivotally to the opposite side walls of the container 1 with the possibility of folding from the outside to one of the side walls.

[0045] The lid 2 is provided with a handle made in a U-shape, repeating the shape of the lid 1 when viewed from above, while the handle is mounted to the lid 2 pivotally to the opposite side walls of the lid 2 with the possibility of folding from the outside to one of the side walls.

[0046] The bucket with wringer for a flat mop is used as follows.

[0047] Clean water is poured into the compartment of container 1, intended for washing the mop, and, if necessary, detergents in liquid or solid (dry) form, which dissolve in water, are added to the water.

[0048] The flat base is folded toward the handle using a hinged connection, and the mop is held by the handle and placed through the opening in lid 2 into the mop's wash compartment. After the absorbent material has become wet, the mop is removed from the wash compartment and placed through the adjacent opening in lid 2 into the wringing compartment of tank 1. As the mop moves up and down in the wringing compartment, scrapers 3, due to their spring-loaded mounting, constantly interact with the surface of the mop's base, squeezing water from its absorbent material, which remains in tank 1. When the mop's surface shifts away from scrapers 3, scraper 3, due to the hinged connection and spring, deflects upward with its front edge following the mop's surface, again exerting pressure on it.

[0049] If the scraper 3, when moving the mop across it, experiences excessive tangential force, then due to the hinge joint it deflects downwards, but due to the spring it continues to act on the absorbent surface of the mop.

[0050] Due to the force-limiting spring, during the operation of scraper 3, current restoring forces are created.

[0051] If the mop's cleaning surface contains localized dirt that protrudes significantly, such as hair or other insoluble dirt, the dirt passes through scraper 3, which, due to its spring force, acts on the dirt and removes (cuts) it from the mop's surface. If the dirt's engagement with the mop's surface is significant and there is a risk of damaging the dirt, scraper 3 deflects downward with the mop's movement, allowing the dirt to pass through. As the mop moves upward, its sharp edge cuts off the dirt.

[0052] Scrapers 3 are mounted to cover 2 by a detachable hinge joint. To remove a scraper, it is sufficient to forcefully tilt one of the side walls of cover 2's niche, which contains an opening for accommodating the end hinge of scraper 3, while simultaneously applying force to scraper 3 by pushing it against the opposite side wall of cover 2's niche, which contains an opening for accommodating the second end hinge of scraper 3, and simultaneously removing scraper 3 from the niche by holding it by the side closest to the first end hinge. After removing the first end hinge, the second side of scraper 3 is removed.

[0053] That is, due to the fact that the scraper 3 is mounted hingedly and spring-loaded to the cover 2, effective wringing is simultaneously ensured due to the constant tangential action on the surface of the mop from the side of the scraper 3 with force, and on the other hand, the scraper 3 is optimally adapted to the surface of the flat mop and thereby gently acts on the mop, which ensures the achievement of the technical result.
