Description

Technical Field

[0001] This invention relates to a cleaning tool, and more particularly to a water-spraying mop that is easy to install. Background Technology

[0002] A mop is a long-handled cleaning tool for scrubbing floors. Existing flat mops generally have a similar structure, including a mop handle and a flat mop head that is movably connected to the handle. The mop head has a cleaning agent. The mop handle is usually formed by bending steel strips, resulting in a thin and uniformly thick handle. To further reduce production, packaging, and transportation costs, the mop handle is divided into 2 to 3 sections. These 2 to 3 shorter sections are connected sequentially to form a longer mop handle. Commonly, mop handle units are connected and fixed by pressing 2 to 4 arc-shaped threads into their ends. While this connection method is convenient, the threads are prone to loosening during use, causing the mop handle to come loose and affecting the user experience. In addition, to make flat mops more convenient to use, mops with a spray function have appeared on the market. Spray mops usually include a detachable water tank on the mop handle, a water pump on the mop handle that communicates with the water tank, and a nozzle for spraying water outwards. The water pump is connected to an operating mechanism for drawing water from the water tank and finally spraying the water from the nozzle. The operating mechanism can be a wrench mechanism, that is, a wrench is provided at the head of the mop handle, the wrench abuts against an auxiliary pressure rod, the auxiliary pressure rod abuts against a connecting rod that passes through the mop handle, and a squeezing mechanism is provided at the tail of the connecting rod. The squeezing mechanism can interact with the pump plug. By operating the wrench, the squeezing mechanism is operated, which drives the pump plug to move. The pump plug has an automatic return device, usually a spring. In the initial state, there is no water in the outlet pump. After the pump plug is pressed down, it rises, and the water in the water tank can be drawn into the outlet pump through the inlet pump. When the pump plug is pressed down again, the water in the outlet pump can be sprayed out through the nozzle. Mops with a spray function require the water tank to be externally located at the bottom or top of the mop handle, affecting the overall appearance and size of the mop, resulting in poor aesthetics. Furthermore, the water tank makes the mop difficult to apply force to or prone to imbalance, leading to a poor user experience. Meanwhile, the wrench-operated squeezing mechanism for spraying water is complex, has many parts, is costly, and prone to malfunction. Some mop handles utilize water storage to improve overall aesthetics, but due to the thin walls of the mop handle units, the threaded connections at the ends are prone to tearing the sealing rings or gaskets, causing leaks. The manufacturing process of mop handles makes it impossible to locally thicken the ends of the mop handle units, and thickening the entire unit to prevent tearing of the sealing rings or gaskets would significantly increase cost and weight. Connecting each adjacent mop handle unit with a connector is also cumbersome. Summary of the Invention

[0027] Preferably, it also includes a connector for connecting to the mop handle, with a hinge shaft on the back side of the mop head. The connector is rotatably mounted on the mop head via the hinge shaft. A locking element is provided on the connector, and a positioning clip that cooperates with the locking element is provided on the mop head or the hinge shaft. The rotation of the connector causes the locking element to rotate. When the locking element rotates to the positioning clip, the positioning clip blocks the locking element from rotating further, thereby blocking the rotation of the connector. The connector and / or the locking element undergo elastic deformation to overcome the obstruction of the positioning clip.

[0028] Preferably, the connector head has a first hinge position with a cross-section that is basically circular. An opening smaller than the hinge shaft is left on the first hinge position.

After the baffle overcomes the obstruction of the stop bar, the other side of the baffle can abut against the stop bar.

[0032] Preferably, a retaining strip is provided on the outside of the baffle. The retaining element includes the retaining strip, which rotates with the connector. When the retaining strip rotates to the stop strip, the stop strip prevents the retaining strip from rotating further, thereby preventing the connector from rotating. The connector and / or the retaining strip undergo elastic deformation to overcome the obstruction of the stop strip. After the retaining strip overcomes the obstruction of the stop strip, the retaining strip can abut against the stop strip. The retaining strip is provided on the outside of the baffle.

[0033] Preferably, the mop head has a long strip-shaped scraper support protrusion on its edge, and scraper support surfaces are provided on both sides of the scraper support protrusion. The scraper is fixed on the scraper support protrusion and the scraper support surfaces, and the bottom shape of the scraper matches the scraper support protrusion and the scraper support surfaces.

[0034] Preferably, a transition groove with a diameter larger than the hinge shaft is formed on the first hinge position. The curvature of the transition groove is one-sixth to one-half of the curvature of the first hinge position. An arc-shaped protrusion with a gradually increasing diameter is provided around the hinge shaft. The other side of the arc-shaped protrusion is transitionally connected to the hinge shaft. The radius of the transition groove is larger than the radius of the arc-shaped protrusion. The first hinge position is dimensionally matched with the hinge shaft. The locking member is the connection point between the first hinge position and the baffle on the side far from the transition groove. The positioning clip is an arc-shaped protrusion. When the connection point between the first hinge position and the baffle on the side far from the transition groove rotates to the arc-shaped protrusion, the arc-shaped protrusion blocks the connector from rotating further. The connector undergoes elastic deformation, thereby overcoming the obstruction of the arc-shaped protrusion and fixing itself on the arc-shaped protrusion.

[0035] Preferably, the mop handle is provided with a movable sleeve, the lower end of which is provided with a brush head. The brush head has a through-hole, and the bottom surface of the through-hole is provided with a squeezing mechanism for squeezing the wiping material. When the mop head is rotated to be parallel with the mop handle, it can be inserted into the through-hole. When the brush head is in a high position, the mop head is disengaged from the through-hole, and when the brush head is in a low position, the lower end of the mop head is inserted into the through-hole. When the brush sleeve and the mop head move relative to each other, the squeezing mechanism squeezes and dehydrates the wiping material.

[0036] Preferably, the device also includes a cleaning bucket, which comprises a first bucket body having an independent wringing area and an independent cleaning area. A first bucket lid is provided on the first bucket body, and the first bucket lid has a cleaning area inlet and a wringing area inlet. A cleaner is provided on the cleaning area inlet, and a wringer is provided on the wringing area inlet. The mop head moves up and down within the cleaning area inlet, and the cleaner squeezes and cleans the material being wiped by the mop head. The mop head moves up and down within the wringing area inlet, and the wringer squeezes and dehydrates the material being wiped by the mop head.

[0037] A further preferred embodiment includes a rinsing bucket, which comprises a second bucket body with a second bucket lid at the top and a drain outlet at the bottom. The second bucket lid has a cleaning port, a flushing chamber, and a drain hole. The cleaning port has a squeezer, and the flushing chamber has a flushing nozzle. When the mop head moves up and down at the cleaning port, the flushing nozzle sprays water onto the mop head's wiping surface. The squeezer squeezes and cleans the wiping surface. After the flushing nozzle stops spraying water, the squeezer squeezes and dehydrates the wiping surface. The water squeezed out from the wiping surface is discharged into the second bucket body through the drain hole and then drained away through the drain outlet.

[0038] In the above technical solution, the connector is positioned by abutting its positioning surface against the end of the mop handle unit. The mop handle unit is then fixedly installed inside by stamping to induce inelastic deformation of the connector and / or the connecting nut. The first sealing device of the connector ensures that water does not leak from the connection between the connector and the mop handle unit; the third sealing device ensures that water does not leak from the connection between the connecting nut and the mop handle unit. This is achieved by creating a longitudinally penetrating first channel on the connector and a longitudinally penetrating second channel on the connecting nut. The connector and the connecting nut are threaded together by an external thread and an internal thread, allowing the first and second channels to pass through while simultaneously connecting and fixing adjacent mop handle units. At this point, the connecting nut abuts against the second sealing device to achieve a sealed connection between the connector and the connecting nut, ensuring that water does not leak from the connection between the connector and the connecting nut. The thickness of the connector and the connecting nut is greater than the thickness of the mop handle unit, thus providing greater strength and rigidity while ensuring that the connecting nut will not tear the second sealing device. The connecting nut is recessed inside the mop handle unit. The outer diameter of the connecting part of the mop handle unit is smaller than the inner diameter of the connecting part of the connecting nut. This ensures that when the connecting head is fixed to the connecting nut, the mop handle unit on the connecting head side fits perfectly into the mop handle unit on the connecting nut side, forming an overlap that further enhances the connection strength between the connecting head and the connecting nut. Simultaneously, the mop handle unit covers the connecting head, resulting in an aesthetically pleasing overall design. In use, simply connecting the external threaded part to the internal threaded part is sufficient to connect and fix adjacent mop handle units, making installation extremely convenient, cost-effective, and highly reliable. The hollow structure of the mop handle stores water without affecting the mop's appearance, resulting in a pleasing overall aesthetic and a superior user experience. One end of the drive rod abuts against or is fixed to the drive rod, while the other end abuts against or is directly fixed to the pressing rod. Pressing the pressing rod causes it to drive the drive rod, which in turn drives the drive rod to slide downwards along the mop handle, thereby driving the water pump to spray water from the nozzle. The drive rod's structure is simple, has few parts, is highly reliable, and is not easily damaged. By incorporating a metal reinforcing rod along the length of the mop head, the bending strength of the mop head is effectively increased, preventing inward deformation and extending its service life. Simply placing the reinforcing rod in the positioning groove and then snapping the base plate onto the cover plate secures the reinforcing rod between the base plate and cover plate, making assembly simple and convenient. The base plate and cover plate form a cavity to hold the cleaning fluid. When the cleaning fluid is added to the cavity through the filling port, it permeates evenly and slowly through multiple through-holes to the underside of the base plate, wetting the object being wiped. Wiping with the object creates porous foam for deep cleaning. The scraper is formed through secondary injection molding on the mop head, ensuring simple and reliable fixation.By incorporating a locking mechanism on the connector head, and a positioning clip on the mop head or hinge shaft that mates with the locking mechanism, the connector head rotates, causing the locking mechanism to rotate. When the locking mechanism rotates to the positioning clip, the positioning clip prevents further rotation of the locking mechanism, thereby preventing the connector head from rotating. The connector head and / or locking mechanism undergo elastic deformation to overcome the obstruction of the positioning clip. The squeegee, protruding from the back edge or side of the mop head, facilitates quick and easy removal of water stains from floors or glass surfaces, significantly enhancing the mop head's functionality and user experience.

[0071] The present invention will be further described below with reference to the accompanying drawings:

[0072] like Figures 1 to 32As shown, this easy-to-install water-spraying mop includes a mop handle 100 and a mop head 1 movably connected to the mop handle 100. The mop head 1 has a wiping agent (not shown in the attached diagram). The mop handle 100 has a hollow structure to hold water. A nozzle 101 is provided on the mop handle 100. A water pump 110 is located inside the mop handle, and a drive rod 111 is provided on the water pump 110. The drive rod 111 can slide up and down inside the mop handle 100, thereby driving the water pump 110 to spray water from the nozzle 101. A handle 120 is sleeved at the end of the mop handle 100. Removing the handle 120 allows water to be added to the mop handle 100. The water inlet 130 can be located on the mop handle 100 or on the handle 120. In this embodiment, the water inlet 130 is located on the handle 120, and the water inlet 130 is provided with an openable and closable sealing cover 140. The sealing cover 140 is provided with a first one-way valve 141 that only allows air to flow from the outside of the handle to the inside of the handle. The sealing cover 140 and the handle 120 are flexibly connected by rubber to prevent the sealing cover 140 from being lost. A transmission rod 150 is also provided inside the mop handle 100. One end of the transmission rod 150 abuts against or is directly fixed to the drive rod 111, and the other end abuts against or is directly fixed to the pressing rod 160. The pressing rod 160 and the handle 120 are sealed together by a sealing ring 161, and the pressing rod 160 can slide up and down along the handle 120 to drive the transmission rod to rise and fall. A limiting surface (not shown in the attached figure) is provided at the end of the handle 120, so that the pressing rod 160 maintains a sealed relationship with the handle 120 while sliding along the handle 120 and will not slip off the handle 120. Water is injected into the mop handle 100 through the water inlet 130. The hollow cavity of the mop handle 100 serves as a water storage area, avoiding the problem of the water tank being externally located at the bottom or top of the mop handle, which would affect the overall appearance and size of the mop, resulting in poor aesthetics, difficulty in applying force to the mop, or easy imbalance, leading to a poor user experience. It also facilitates convenient cleaning and wringing of the mop head using the existing washing bucket. Pressing the pressing lever 160 pushes the transmission rod 150 to slide down along the mop handle 100, thereby causing the drive rod 111 to slide down and drive the water pump 110 to spray water from the nozzle 101, realizing the water spraying function. The water pump 110 is existing technology and may include a pump housing 112, a piston rod 113, and a return spring 114. The pump housing 112 is fixed inside the mop handle 100. The nozzle 101 is located at the lower part of the pump housing 112 and is connected to the water outlet 115 on the pump housing 112. The piston rod 113 passes through the pump chamber of the pump housing 112 and is driven by the drive rod 111 to slide up and down. The lower end of the piston rod 113 is connected to a piston 116. The piston rod 113 is hollow inside and has a second one-way valve 117 at the outlet end of the piston rod 113 that only allows water to flow from the inner cavity of the piston rod 113 to the pump chamber. The return spring 114 keeps the piston 116 in an upward return trend.Therefore, when the pressing lever 160 is pressed, the pressing lever 160 drives the driving lever 111 to slide downwards. The driving lever 111 then drives the piston rod 113 and piston 116 to slide downwards. Since the second one-way valve 117 only allows water to flow from the inner cavity of the piston rod 113 to the pump cavity, the inner cavity of the piston rod 113 is not connected to the pump cavity at this time. The water in the pump cavity is squeezed and sprayed out through the nozzle 101 through the water outlet 115 (similar to the principle of a syringe), realizing the water spraying function. Subsequently, the piston 116 is kept in the upward reset position under the action of the return spring 114, and the piston rod 113, together with the driving lever 111, the transmission rod 150, and the pressing lever 160, moves upwards to the reset position. During the repositioning process of piston 116 by moving upwards and resetting via return spring 114, a pressure difference is created between the pump chamber and the inner cavity of piston rod 113. Since the inner cavity of piston rod 113 is connected to the inner cavity of mop handle 100, water in the inner cavity of piston rod 113 flows from the inner cavity of piston rod 113 to the pump chamber through the second one-way valve 117, replenishing the water in the pump chamber. Water in the inner cavity of mop handle 100 then flows back to the inner cavity of piston rod 113, achieving repeated water spraying. During the repositioning process of drive rod 111, transmission rod 150, and pressing rod 160, some water in mop handle 100 is discharged into the pump chamber through the inner cavity of piston rod 113, creating a negative pressure in the inner cavity of mop handle 100. External air is then drawn into the inner cavity of mop handle 100 through the first one-way valve 141, ensuring a consistent pressure difference between the inside and outside of mop handle 100 and enabling rapid repositioning of drive rod 111, transmission rod 150, and pressing rod 160. The drive rod 111 has a simple drive structure and few parts, thus ensuring high reliability and resistance to damage. In this embodiment, the mop handle 100 includes several mop handle units 102, such as 2 to 4 units, preferably 3 units. Adjacent mop handle units 102 are sequentially sealed together by a connector 200. The connector 200 includes a connector head 300 and a connector nut 400, both of which are cylindrical with a hollow structure. The connector head 300 and the connector nut 400 are respectively fixed at the connection points of adjacent mop handle units. The connector head 300 includes a first sealing device 310, an external threaded connection part 330, and a longitudinally penetrating first channel 340. When the connector head 300 is fixed to the mop handle unit 102, the side of the connector head near the first sealing device 310 is installed on the mop handle unit 102. The internal structure achieves a sealed connection between the connector 300 and the mop handle unit 102, preventing water leakage between them. The connector 400 includes a third sealing device 410, an internal threaded connection part 420, and a longitudinally penetrating second channel 430. The internal threaded connection part 420 is disposed on the second channel 430. When the connector 400 is fixed to the mop handle unit, the side of the connector 400 near the third sealing device 410 is installed inside the mop handle unit, achieving a sealed connection between the connector 400 and the mop handle unit 102, preventing water leakage between them. The mop handle unit achieves connection with the connector 300 and the connector 400 respectively through non-elastic deformation.Specifically, the mop handle unit can be fixed inside by stamping to induce inelastic deformation of the connector and / or connector nut, which is equivalent to locally thickening the mop handle unit. The connector 300 and connector nut 400 are connected by an external threaded connection part 330 and an internal threaded connection part 420, which connects the first channel and the second channel and simultaneously achieves the sequential connection of two adjacent mop handle units. A second sealing device 320 is also provided on the connector and / or the connector nut. When the second sealing device 320 is only provided on the connector 300, after the connector 300 and the connector nut 400 are threadedly connected through the external threaded connection part 330 and the internal threaded connection part 420, the end of the connector nut can abut against the second sealing device 320 to achieve a sealed connection between the connector and the connector nut. When the second sealing device 320 is only provided on the connector nut, the second sealing device 320 is installed at the connection between the internal threaded connection part 420 and the second channel. After the connector 300 and the connector nut 400 are threadedly connected through the external threaded connection part 330 and the internal threaded connection part 420, the end of the connector can abut against the second sealing device to achieve a sealed connection between the connector and the connector nut. Alternatively, the second sealing device 320 can be provided on both the connector and the connector nut to prevent water leakage from the connection between the connector 300 and the connector nut. The first sealing device 310, the second sealing device 320 and the third sealing device 410 each include at least one sealing ring 311 and a sealing groove 312. The sealing ring is fitted onto the sealing groove. Since the thickness of the connector and the connecting nut is greater than the thickness of the mop handle unit, when the connector 300 is fixed on the connecting nut 400, the end of the connecting nut will not tear the second sealing device 320, and the processing cost is greatly reduced.

[0073] In one embodiment, the connecting nut 400 is installed inside the mop handle unit 102, and the external threaded connection portion 420 protrudes from the mop handle unit. Furthermore, the connecting nut 400 is recessed inside the mop handle unit 102, and the outer diameter of the mop handle unit connection 103 of the connector head is smaller than the inner diameter of the mop handle unit connection 104 of the connecting nut. Thus, when the connector head 300 is fixed to the connecting nut 400, the mop handle unit on the connector head side is precisely inserted into the mop handle unit on the connecting nut side, forming an overlap that further enhances the connection strength between the connector head and the connecting nut. Simultaneously, the mop handle unit covers the connector head, resulting in an aesthetically pleasing overall appearance. In use, simply connecting the external threaded connection portion with the internal threaded connection portion achieves the connection and fixation of two adjacent mop handle units, making installation extremely convenient, cost-effective, and highly reliable. Furthermore, the outer diameters of the sealing rings of the first and third sealing devices are larger than the inner diameter of the mop handle unit, further ensuring the sealing effect of the first and third sealing devices. Furthermore, a positioning surface 350 can be provided on the connector 300. The connector 300 abuts against the end of the mop handle unit through the positioning surface 350 to achieve rapid positioning of the connector.

[0074] In a preferred embodiment, the transmission rod 150 is provided with a plurality of protrusions 151, which can slide precisely along the inner wall of the mop handle 100, preventing the transmission rod 150 from vibrating or shifting inside the mop handle 100, and further ensuring the accuracy and reliability of the transmission of the transmission rod 150. Furthermore, the protrusions 151 are arranged in a circumferential array on the transmission rod 150, with gaps between adjacent protrusions 151, further increasing the inner volume of the mop handle 100 and allowing for smoother water flow. The transmission rod 150 also has 2 to 4 rods, with each rod abutting each other end-to-end, further reducing the packaging size of this easy-to-install spray mop.

[0075] In a preferred embodiment, this easy-to-install spray mop also includes a connector 2 connected to the mop handle 100. A hinge shaft 11 is provided on the back side of the mop head 1. The connector 2 is rotatably mounted on the mop head 1 via the hinge shaft 11. At least one reinforcing rod 3 is provided along the length of the mop head. The reinforcing rod 3 is made of metal material, such as stainless steel, aluminum, or alloy steel. It can be made into a rod shape or a tube shape, and the cross-section can be circular or rectangular. The reinforcing rod 3 is positioned near the edge of the mop head 1 to act as a reinforcing rib for the edge of the mop head, effectively increasing the bending strength of the mop head, preventing the mop head 1 from deforming inward, and extending the service life of the mop head. In this embodiment, there are two reinforcing rods 3, respectively located on both sides of the hinge shaft, to prevent inward deformation of the two long sides of the mop head 1.

[0076] In a preferred embodiment, the mop head 1 includes a base plate 4 and a cover plate 5. The cover plate 5 is detachably mounted on the base plate 4, and a reinforcing rod 3 is disposed between the base plate 4 and the cover plate 5. In one embodiment, a positioning groove 51 is provided on the inner side of the cover plate 5, and the reinforcing rod can be placed precisely within the positioning groove 51. The base plate and the cover plate can be fixed by snap-fit, threaded connection, or a combination of snap-fit ​​and threaded connection, further improving the bonding effect between the base plate and the cover plate. When the base plate is fixed to the cover plate, the reinforcing rod 3 is fixed within the positioning groove 51. The base plate and the positioning groove 51 naturally limit the reinforcing rod 3, fixing it between the base plate 4 and the cover plate 5. When the base plate and the cover plate are threadedly connected, corresponding threaded holes 510 are provided on the base plate and the cover plate. These threaded holes 510 are preferably located on both sides and / or the top of the reinforcing rod, making the reinforcing rod 3, the base plate 4, and the cover plate 5 form a whole, improving the overall bending strength of the reinforcing rod 3, the base plate 4, and the cover plate 5, and simultaneously improving the fixing effect of the reinforcing rod 3.

[0077] In a preferred embodiment, an elongated hole 52 is provided on the positioning groove 51, and the positioning groove 51 protrudes from the cover plate 5, so that after the reinforcing rod 3 is placed in the positioning groove 51, it is exposed to the consumer's line of sight through the elongated hole 52, making it easier for the consumer to quickly select the mop head with the reinforcing rod.

[0078] In a preferred embodiment, the base plate 4 and the cover plate 5 form a receiving cavity to contain cleaning fluid. The cover plate 5 has at least one inlet 53, and the base plate 4 has an outlet 41. When cleaning fluid is added to the receiving cavity through the inlet 53, it permeates through the outlet 41 to the bottom side of the base plate 4. A removable wiping material is placed on the bottom side of the base plate 4. The cleaning fluid wets the wiping material, and wiping with the wiping material creates porous foam, achieving deep cleaning of the floor. In this embodiment, at least two or four inlets 53 are provided and symmetrically arranged on both sides of the cover plate 5. Several groups of outlets 41 are evenly arranged on the base plate 4. The outlets 41 are multiple arrays of small through-holes 42, which allow the cleaning fluid to permeate more evenly and slowly to the bottom side of the base plate 4, thereby evenly and slowly wetting the wiping material and preventing rapid loss of cleaning fluid.

[0079] In a preferred embodiment, the cover plate 5 has downwardly extending side edges 50 around its perimeter, and the bottom plate 4 has several slots 43 on its edge. The inner side of the side edges 50 of the cover plate 5 has corresponding protrusions 54, one-to-one with the slots 43. Alternatively, the bottom plate has several protrusions on its edge, and the inner side of the side edges 50 of the cover plate has slots corresponding to the protrusions. By aligning the slots 43 with the protrusions 54 and simultaneously pressing the bottom plate and cover plate, the slots and / or protrusions elastically deform, allowing the protrusions to engage with the slots, thus connecting the bottom plate and cover plate. Assembly is simple and convenient. In another preferred embodiment, the liquid inlet 41 is also provided with a fixing clip 6, made of a soft, elastic material, such as silicone. The fixing clip 6 has a perforated portion 61 for easy addition of cleaning fluid, and the fixing clip 61 also has several strip-shaped holes 62 connected to the perforated portion 61. When it's necessary to secure electrostatic dust removal paper, old clothes, or old towels, the adjacent slots 62 easily undergo elastic deformation under the squeezing action of these items, thus locking them into the corresponding slots for fixation. This prevents the electrostatic dust removal paper from slipping off the mop head, and allows for convenient cleaning of floors or windows using old clothes and towels, achieving resource reuse and improving the user experience. Preferably, the slots 62 are arranged radially in the hollow section 61 to enhance the overall aesthetics of the mop head.

[0080] In a preferred embodiment, a fixing groove 63 is provided circumferentially on the side edge of the fixing clip 6. Since the hardness of the side edge of the fixing groove 63 is much less than that of the cover plate 5, the side edge of the fixing groove 63 is more likely to undergo elastic deformation, thereby fixing the fixing groove 63 around and fixing it to the edge of the liquid filling port 53, so that the fixing clip 6 can be detachably fixed to the liquid filling port 53.

[0081] In a preferred embodiment, a scraper 7 is provided on the back side of the mop head 1 along its length. The scraper 7 is located at the edge of the mop head 1 and protrudes from the back edge plane or the side plane of the mop head 1, so as to scrape water stains on the floor or glass. In this embodiment, the scraper 7 is integrally fixed to the mop head 1 by secondary injection molding, eliminating the assembly process between the scraper and the mop head. Therefore, the scraper is reliably fixed, the mop head is easy to assemble, and there is no limitation on whether the mop head has a single or double layer structure. A locking device is provided on the connector 2, and a positioning clip that cooperates with the locking device is provided on the mop head or hinge shaft. In this way, the rotation of the connector 2 causes the locking device to rotate. When the locking device rotates to the positioning clip, the positioning clip prevents the locking device from rotating further, and thus prevents the connector from rotating. When the connector 2 is rotated forcefully, the connector and / or locking device undergo elastic deformation, thereby overcoming the obstruction of the positioning clip. After the connector and / or locking device overcomes the obstruction of the positioning clip, the locking device can rest against the positioning clip. Because the scraper blade exerts a force on the mop handle along the axis of the mop handle during the scraping process, this force only forces the locking device against the positioning clip, and does not force the locking device to rotate with the connector. Therefore, the locking device can keep the connector and the mop head stable under the obstruction of the positioning clip, ensuring that the mop head will not flip or shake. In this way, the scraper blade can be used to quickly and easily scrape away water stains on the floor or glass surface, greatly improving the user experience. In this embodiment, the connector 2 has a first hinge position 21 with a cross-section that is basically annular. An opening 22, smaller than the hinge shaft 11, is provided on the first hinge position 21. Baffles 23 extend from both sides of the opening 22, with the distance between the two baffles gradually increasing from near to far of the first hinge position 21. This facilitates elastic deformation of the opening 22, allowing the first hinge position 21 to be hinged onto the hinge shaft 11, thus enabling the first hinge position 21 to be rotatably mounted on the hinge shaft 11. The connector 2 also has a second hinge position 24, which is basically perpendicular to the first hinge position 21. The second hinge position 24 is connected to the external mop handle 10, enabling a movable connection between the external mop handle 10 and the mop head, as well as flexible rotation of the mop head.

[0082] In a preferred embodiment, the positioning clip includes a stop strip 81 disposed on the back side of the mop head 1. The clip can be one of the aforementioned baffles 23. The baffle 23 rotates with the connector 2. When one side of the baffle 23 rotates to the stop strip 81, the stop strip 81 prevents the baffle 23 from rotating further, thus preventing the connector 2 from rotating to the left. When the mop handle is forcefully rotated, the baffle 23 presses against the stop strip 81, causing the connector 2 and / or the baffle 23 to undergo elastic deformation, thereby overcoming the obstruction of the stop strip 81. After the baffle 23 overcomes the obstruction of the stop strip 81, the other side of the baffle 23 can rest against the other side of the stop strip 81, allowing the connector 2 and the connected mop handle to remain stable under the resistance of the stop strip 81, ensuring that the mop head does not wobble or flip. When the mop handle is forcefully rotated again in the opposite direction, the baffle 23 overcomes the obstruction of the stop strip 81 in the opposite direction, and the mop handle resumes flexible rotation.

[0083] Alternatively, a retaining strip 231 can be provided on the outside of one of the baffles 23. The retaining strip 231 rotates with the connector 2. When the retaining strip 231 rotates to the stop bar 81, the stop bar 81 blocks the retaining strip 231 from rotating further, thereby blocking the connector 2 from rotating. When the mop handle is rotated forcefully, the retaining strip 231 presses against the stop bar 81, and the connector and / or the retaining strip undergo elastic deformation to overcome the obstruction of the stop bar 81. After the retaining strip 231 overcomes the obstruction of the stop bar, the retaining strip can rest against the stop bar, so that the connector 2 and the mop handle connected to it can be kept stable by the obstruction of the stop bar 81, ensuring that the mop head will not shake or flip. The ends of the stop bar 81 and the retaining strip 231 can be curved surfaces to make it easier to achieve elastic deformation, or they can be flat or inclined surfaces, so that after the retaining strip 231 overcomes the obstruction of the stop bar, the flat or inclined surface of the retaining strip can rest against the flat or inclined surface of the stop bar, further ensuring that the mop head will not shake or flip. The retaining strip 231 can be located at the lower edge of the baffle 23, or at the middle or lower part of the baffle 23. When the mop handle is rotated again with reverse force, the retaining strip 231 overcomes the obstruction of the stop strip 81, and the mop handle resumes flexible rotation. Adjusting the size of the baffle 23, the position and width of the retaining strip 231, or the position or height of the stop strip 81 can control the fixed angle between the connector and the mop head 1, keeping the fixed angle between the mop handle and the mop head 1 within the range of 15° to 45°. Because the stop strip 81 only affects the leftward rotation of the connector and does not affect the rightward rotation of the mop handle at the second hinge position, the setting of the stop strip 81 does not affect the flexibility of the mop head, or has minimal impact on the flexibility of the mop head.

[0084] In a preferred embodiment, a transition groove 25 with a diameter larger than that of the hinge shaft 11 is formed on the first hinge position 21. The curvature of the transition groove 25 is one-sixth to one-half of the curvature of the first hinge position 21. An arc-shaped protrusion 251 with a gradually increasing diameter is provided around the hinge shaft 11. The other side of the arc-shaped protrusion 251 is transitionally connected to the hinge shaft 11. The radius of the transition groove 25 is larger than the radius of the arc-shaped protrusion 251. Therefore, the transition groove 25 can rotate around the axis along the arc-shaped protrusion. The first hinge position 21 and the hinge shaft 11 are dimensionally matched. At this time, the locking element is the connection point 232 between the side of the first hinge position 21 away from the transition groove 25 and the baffle 23. The positioning clip is the arc-shaped protrusion 251. The radius of the hinge 21 is smaller than the radius of the arc-shaped protrusion 251. Therefore, when the connection 232 between the first hinge 21 and the baffle rotates to the arc-shaped protrusion 251, the arc-shaped protrusion 251 prevents the first hinge 21, i.e., the connector head, from rotating further. By forcefully rotating the mop handle, the connection 232 presses against the arc-shaped protrusion 251. The connection 232 of the connector head undergoes elastic deformation, overcoming the obstruction of the arc-shaped protrusion, and then partially recovers its elastic deformation, fixing itself on the arc-shaped protrusion 251. Because the connection 232 and the arc-shaped protrusion 251 are in close contact and still have some elastic deformation, the connector head 2 can remain stable with the mop head, and the mop head will not wobble or flip. By forcefully rotating the mop handle again in the opposite direction, the connection 232 overcomes the obstruction of the arc-shaped protrusion 251 and resumes flexible rotation. In this embodiment, the arc-shaped protrusion 251 extends no more than one-third of the total length of the hinge shaft 11 along its axial direction. The extension length of the transition groove 25 matches the extension length of the arc-shaped protrusion 251, which facilitates elastic deformation at the connection point 232. Adjusting the position or curvature of the arc-shaped protrusion 251 controls the fixed angle between the connector and the mop head 1, keeping the fixed angle between the mop handle and the mop head 1 within the range of 15° to 45°. Because the arc-shaped protrusion 251 only affects the leftward rotation of the connector and does not affect the rightward rotation of the mop handle at the second hinge position, the arc-shaped protrusion 251 does not affect the flexibility of the mop head, or has minimal impact on the flexibility of the mop head.

[0085] In a preferred embodiment, a long strip-shaped scraper support protrusion 71 is provided on the edge of the mop head 1, and scraper support surfaces 72 are provided on both sides of the scraper support protrusion 71. The scraper 7 is fixed to the scraper support protrusion and the scraper support surfaces under the action of the scraper support protrusion 71 and the two scraper support surfaces 72. The bottom shape of the scraper matches the scraper support protrusion and the scraper support surfaces. This setting can increase the contact area between the scraper 7 and the mop head 1, and further improve the reliability of the scraper fixation.

[0086] In a preferred embodiment, a movable sleeve 500 is provided on the mop handle 100. The sleeve 500 includes a sleeve head 501 at the lower end and a guide sleeve 502 connected to the sleeve head 501. The upper end of the sleeve 500 is cylindrical and fits onto the mop handle 100. The sleeve head 501 is rectangular and has a through-hole 503 in the middle. The bottom surface of the through-hole 503 extends in both length and width directions, and a squeezing mechanism 505 is provided on the bottom surface. The squeezing mechanism 505 includes a scraper and scraper teeth for squeezing the wiping material to remove dirt and dirty water. Thus, when the mop head is rotated to be parallel to the mop handle, it can be inserted into the through-hole. When the sleeve head is in a high position, the mop head is disengaged from the through-hole; when the sleeve head is in a low position, the lower end of the mop head is inserted into the through-hole. When the sleeve and the mop head move relative to each other, the squeezing mechanism squeezes and dehydrates the wiping material. When the item needs to be cleaned, rinse it under the tap, then push the guide sleeve down. The squeezing mechanism will squeeze the item to remove dirt and water. The brush head will move from a high position to a low position and then back to a high position. Repeat this process to clean and dry the item. It is simple and easy to use.

[0087] In a preferred embodiment, a cleaning tool includes a conveniently installed spray mop and a washing bucket 600 as described above. The washing bucket 600 includes a first bucket body 610, which is divided into a washing area and a wringing area. The washing area is filled with water for washing the flat mop, and the wringing area is used to wring out the flat mop. A first bucket cover 640 is detachably mounted on the first bucket body 610. The first bucket cover 640 has a washing area inlet 650 and a wringing area inlet 660. The washing area inlet 650 is located above the washing area, and a cleaner 670 is installed inside the washing area inlet 650. A wringer 680 is installed on the wringing area inlet. The cleaner 670 can be a squeezing strip, brush teeth, etc. When the mop head moves up and down inside the washing area inlet 650, the cleaner 670 squeezes and cleans the mop head. As the mop head moves up and down within the wringing area inlet, the wringer inside the inlet dehydrates the items being wiped, thus enabling rapid cleaning and dehydration of the items when combined with an existing washing tub.

[0088] In another preferred embodiment, a cleaning tool includes the easy-to-install spray mop and rinsing bucket 700 described above. The rinsing bucket 700 has a second bucket body 710, a second bucket cover 720 at the upper opening of the second bucket body 710, and a drain outlet 730 at the bottom of the second bucket body 710. The second bucket cover 720 has a cleaning port 740, a water tank 800, and a drain hole 901. A squeezer is provided on the cleaning port 740. In one embodiment, the squeezer includes a squeegee 900. The water tank 800 and the squeegee 900 are connected. A water outlet 801 is provided on the side wall of the water tank, located above the squeegee 900, so that water flushed from the water outlet 801 can flow directly onto the mop being wiped by the end of the squeegee. The drain hole 901 is provided on the squeegee for draining the wastewater after cleaning. The lower part of the squeegee 900 can be equipped with comb teeth 910 for combing the wiping material and removing hair and other filamentous substances. When the mop head moves up and down at the washing port 740, the water inlet 801 sprays water onto the wiping material on the back of the mop head, and the squeegee 900 squeezes and washes the wiping material. The water used to wash the mop head is drained away through the drain hole. After the water inlet stops spraying, the squeegee 900 squeezes and dehydrates the wiping material. The water squeezed out from the wiping material is drained into the second bucket through the drain hole 901 and then drained away through the drain outlet 730, thus achieving rapid washing and dehydration of the wiping material when combined with the existing rinsing bucket.

[0089] In the above technical solution, the connector 300 abuts against the end of the mop handle unit via the positioning surface 350, achieving rapid positioning of the connector. Then, the connecting nut is placed in the preset position of the mop handle unit. By stamping the mop handle unit to cause inelastic deformation, the connector and / or connecting nut are fixedly installed inside the mop handle unit, effectively thickening the mop handle unit locally. The connector 300 and connecting nut 400 are connected by an external threaded connection part 330 and an internal threaded connection part 420, connecting the first and second channels and simultaneously achieving sequential connection of adjacent mop handle units. When the connector 300 is fixed on the connecting nut 400, the end of the connecting nut precisely abuts against the second sealing device 320, achieving a sealed connection between the connector and the connecting nut, preventing water leakage at the connection point. The mop handle is easy to install, low in cost, has few parts, high reliability, and is less prone to failure. The mop handle is not easily shaken or loosened, and the sealing effect is good.

[0090] Simply place the reinforcing rod in the positioning groove, and then snap the base plate onto the cover plate. This will fix the reinforcing rod between the base plate and the cover plate, as well as the base plate and the cover plate together. The mop head assembly is simple and convenient.

[0091] Remove the sealing cap 140 and open the water inlet 130. Water is injected into the mop handle 100 through the water inlet 130, and the hollow cavity of the mop handle 100 serves as a water storage function. When water spraying is needed, press the pressing rod 160. The pressing rod 160 pushes the transmission rod 150 to slide down along the mop handle 100, thereby causing the drive rod 111 to slide down. The drive rod 111 then drives the piston rod 113 and piston 116 to slide down. The water in the pump chamber is squeezed and sprayed out through the water outlet 115 and the nozzle 101, realizing the water spraying function. Subsequently, piston 116 remains in its upward reset position under the action of return spring 114. Piston rod 113, along with drive rod 111, transmission rod 150, and pressing rod 160, also moves upward. Water inside piston rod 113 flows from its inner cavity to the pump chamber through the second one-way valve 117, replenishing the water in the pump chamber. Water inside mop handle 100 then flows back to piston rod 113, achieving repeated water spraying. During the upward reset process of drive rod 111, transmission rod 150, and pressing rod 160, external air is drawn into the inner cavity of mop handle 1 through the first one-way valve 81, ensuring consistent pressure difference inside and outside mop handle 1 and facilitating rapid upward reset of drive rod 111, transmission rod 150, and pressing rod 160. Drive rod 111 has a simple drive structure with few parts, resulting in high reliability and resistance to damage.

[0092] During use, the cleaning solution is added to the receiving cavity through the filling port or the perforated part. The cleaning solution permeates evenly and slowly to the bottom side of the base plate through multiple through-holes, thus wetting the wiping material. Then, wiping with the side of the wiping material creates porous foam, achieving deep cleaning of the floor. When it is necessary to fix electrostatic dust removal paper, old clothes, or old towels, the adjacent strip holes easily undergo elastic deformation under the squeezing action of the electrostatic dust removal paper, old clothes, or old towels, thus securing them in the corresponding strip holes. Therefore, the electrostatic dust removal paper is not easy to slip off the mop head. Old clothes and old towels can also be used to conveniently clean floors or glass, achieving resource reuse and improving the user experience.

[0093] When you need to scrape water stains off the floor or glass surface, simply rotate the mop handle until the baffle 23 presses against the baffle strip 81. Then, rotate the mop handle forcefully. The connector 2 and / or the baffle 23 will elastically deform to overcome the obstruction of the baffle strip 81. After the baffle 23 overcomes the obstruction of the baffle strip 81, the other side of the baffle 23 will press against the other side of the baffle strip 81, so that the connector 2 and the mop handle connected to it can be kept stable by the resistance of the baffle strip 81, ensuring that the mop head will not shake or flip. Flip the scraper 7 to the side closer to the floor or glass surface to easily scrape water stains. Rotate the mop handle forcefully again in the opposite direction. After the baffle 23 overcomes the obstruction of the baffle strip 81 in the opposite direction, it will resume flexible rotation. Alternatively, rotate the mop handle until the stop bar 81 blocks the further rotation of the retaining strip 231, thereby blocking the rotation of the connector 2. Then, rotate the mop handle forcefully, causing the retaining strip 231 to press against the stop bar 81. The connector and / or the retaining strip undergo elastic deformation to overcome the obstruction of the stop bar 81. After the retaining strip 231 overcomes the obstruction of the stop bar, it rests against the stop bar, allowing the connector 2 and the mop handle connected to it to remain stable under the resistance of the stop bar 81, ensuring that the mop head will not wobble or flip. Flip the scraper to the side to be close to the ground or glass surface for convenient scraping of water stains. Rotate the mop handle forcefully again in the opposite direction, and the retaining strip 231 overcomes the obstruction of the stop bar 81 and resumes flexible rotation. Alternatively, rotate the mop handle until the arc-shaped protrusion 251 blocks the first hinge position 21, i.e., the connector, from rotating further. Then, forcefully rotate the mop handle so that the connection 232 presses against the arc-shaped protrusion 251. The connection 232 of the connector undergoes elastic deformation, overcoming the obstruction of the arc-shaped protrusion, and then partially recovers its elastic deformation, fixing itself to the arc-shaped protrusion 251. The connector 2 and the mop head remain stable, and the mop head will not wobble or flip. Flip the scraper 7 to the side near the ground or glass surface for convenient wiping of water stains. Then, forcefully rotate the mop handle again in the opposite direction. The connection 232 overcomes the obstruction of the arc-shaped protrusion 251 and resumes flexible rotation.

[0094] This embodiment is merely an illustration of the concept and implementation of the present invention and is not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
