Description

Technical Field

[0001] This invention belongs to the field of flat mop technology, and particularly relates to a method for cleaning flat mops by separating clean and dirty parts. Background Technology

[0002] Flat mops, as a common cleaning tool, are widely used in various scenarios such as homes and commercial spaces due to their large cleaning area, convenient operation, and good cleaning effect. As people's quality of life improves and their demands for cleaning efficiency and hygiene increase, flat mops are also constantly evolving and improving.

[0003] Existing flat mops typically require soaking the mop in a bucket of water before cleaning. During this process, the clean water mixes with the dirt on the floor, creating wastewater. This wastewater then remains on the mop, re-contaminating the cleaned area as the mop moves, resulting in poor cleaning performance and requiring repeated cleaning of the same area, significantly reducing cleaning efficiency. Furthermore, this method of use wastes water, and because the wastewater mixes with the clean water, it is difficult to effectively collect and treat the wastewater, which is detrimental to environmental protection and hygiene maintenance.

[0004] Therefore, the inventors dedicated themselves to designing a cleaning method for flat mop heads to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method for separating clean and dirty parts in a flat mop, which can improve the cleaning effect, efficiency, and hygiene of the flat mop.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A cleaning method for separating clean and dirty parts in a flat mop includes the following steps: Clean water supply: The clean water pump in the handle assembly draws clean water from the clean water tank on the handle assembly and delivers it to the clean water chamber in the center of the flat mop head. The clean water in the clean water chamber is divided and then converges into the water outlet chamber of the flat mop head. It is then absorbed by the absorbent strips of the flat mop head and permeates into the mop cloth of the flat mop head, providing a metered amount of clean water to the center of the cleaning surface of the flat mop head along its length. Wastewater discharge: During the cleaning process, wastewater enters from the side of the flatbed mop head and is absorbed by the mop cloth and absorbent strips in sequence. Then, the wastewater pump in the handle assembly draws a vacuum to suck up the wastewater absorbed by the absorbent strips into the various suction chambers on the same side of the flatbed mop head. Then, the wastewater in the various suction chambers on the same side merges into the wastewater chamber. Finally, the water in the wastewater chamber is sucked into the wastewater tank on the handle assembly, thus sucking out the wastewater from the side of the flatbed mop head.

[0007] As an improvement to the cleaning method for separating clean and dirty parts using the flat mop of the present invention, the method further includes the following steps: Venting: The gas in the wastewater tank is vented through the vent pipe to the water outlet chamber of the flat mop head, and the gas in the water outlet chamber is vented to the outside of the flat mop head through the vent groove.

[0008] As an improvement to the cleaning method of separating clean and dirty parts in the flat mop of the present invention, the flat mop head is hinged to the lower end of the handle assembly. The opening on the side of the handle assembly is detachably connected to a clean water tank and a dirty water tank. The clean water tank is connected to the clean water chamber through a clean water pipe, and the dirty water tank is connected to the dirty water chamber through a dirty water pipe. The clean water pump and the dirty water pump are both housed in the handle assembly and are respectively installed on the clean water pipe and the dirty water pipe.

[0009] As an improvement to the cleaning method for separating clean and dirty parts in the flat mop of the present invention, the flat mop head includes a mop head body. A foam substrate and a cleaning component are stacked and attached sequentially from top to bottom on the bottom of the mop head body. The mop head body is provided with an independent clean water chamber and a dirty water chamber. The clean water chamber provides clean water to the cleaning component through a clean water channel. A water absorption chamber is provided below the clean water chamber. The dirty water chamber is connected to the water absorption chamber through a water absorption hole to absorb the dirty water on the cleaning component under negative pressure.

[0010] As an improvement to the cleaning method of separating clean and dirty parts in the flat mop of the present invention, a wastewater platform is provided on the bottom of the mop head body. The wastewater platform passes through the foam substrate. A water absorption groove is provided on the bottom end face of the wastewater platform. The cleaning component covers the opening of the water absorption groove, and the edge of the opening of the water absorption groove presses against the cleaning component to form a water absorption cavity. The water absorption groove is provided with water absorption holes and multiple protrusions for preventing the water absorption holes from being blocked.

[0011] As an improvement to the cleaning method of separating clean and dirty parts in the flat mop of the present invention, the water absorption hole and the protrusion are both located on the inner top wall of the water absorption groove, and the height of all the protrusions is less than the depth of the water absorption groove to prevent the water absorption hole from being blocked.

[0012] As an improvement to the cleaning method of the flat mop of the present invention, an inner isolation layer is formed between the foam substrate and the cleaning component through a dispensing process. The inner isolation layer is arranged around the water absorption cavity to seal and separate the dirt absorption area and the clean water output area between the foam substrate and the cleaning component.

[0013] As an improvement to the cleaning method for separating clean and dirty parts in the flat mop of the present invention, the notch of the dirt-absorbing area is connected to the outside through a non-linear venting channel. A groove is formed by the inward recess of the bottom of the foam substrate. The venting channel is located at the bottom of the foam substrate and in the groove. The cleaning component is placed on the opening of the groove to form a water outlet cavity. The water outlet cavity is connected to the clean water cavity through the clean water channel. The water outlet cavity is arranged in a circle around the water-absorbing cavity. A dispensing platform is protruding in the groove. The dispensing platform is arranged in a circle around the water-absorbing cavity. The notch of the dirt-absorbing area is opened on the dispensing platform. The dispensing platform is fixedly connected to the cleaning component through the inner isolation layer.

[0014] As an improvement to the cleaning method of separating clean and dirty parts in the flat mop of the present invention, the edge of the foam substrate is fixedly connected to the edge of the cleaning component by a dispensing process to form an annular outer isolation layer, so as to seal and isolate the water outlet area from the outside world.

[0015] As an improvement to the cleaning method for separating clean and dirty parts in the flat mop of the present invention, the cleaning component includes an absorbent cloth strip and a mop cloth. The absorbent cloth strip and the mop cloth are sequentially attached to the bottom of the foam substrate from top to bottom. The absorbent cloth strip has a water absorption rate greater than that of the mop cloth. The absorbent cloth strip has a water inlet hole at a position opposite to the water absorption cavity, allowing wastewater on the mop cloth to enter the water absorption cavity. The diameter of the water inlet hole is larger than the fabric gap of the absorbent cloth strip.

[0016] Compared with existing technologies, the clean and dirty separation cleaning method of the flat mop of the present invention optimizes the path and mechanism of clean water supply and wastewater discharge, realizes the quantitative supply of clean water to the center of the cleaning surface along the length of the flat mop head, and the efficient and thorough discharge of wastewater from the side of the flat mop head, thus achieving clean and dirty separation cleaning. At the same time, it improves the synergy between the clean water supply system and the wastewater discharge system. It has the advantages of simple structure, convenient operation, and good cleaning effect, and can improve the cleaning effect, efficiency and hygiene of the flat mop. Attached Figure Description

[0024] Reference Figure 1 and Figure 2 The top opening of the clean water tank 8 is sealed with a clean water tank cover 81, and the bottom of the clean water tank 8 is provided with a one-way valve. The one-way valve can effectively prevent water backflow and ensure the stability of the water supply system.

[0025] Reference Figure 1 and Figure 2The two openings on the side of the handle housing 61 are separated by a body 62. The body 62 is located between the clean water tank 8 and the wastewater tank 7. The top end face of the body 62 is provided with an insertion hole 622 for the one-way valve at the bottom of the clean water tank 8 to be inserted. The insertion hole 622 is provided with a water outlet connector 621. The top end of the clean water pipe 122 is inserted into the body 62 and connected to the water outlet connector 621 at the top of the body 62. When the clean water tank 8 covered with the clean water tank cover 81 is located at the opening at the top of the handle housing 61, the one-way valve at the bottom of the clean water tank 8 is connected to the water outlet connector 621 in the insertion hole 622 at the top of the body 62, so that the clean water tank 8 can be connected to the clean water chamber 15. The lower side of the body 62 is provided with an exhaust port 623 and a wastewater port 624 at intervals.

Both the sewage insertion tube 712 and the exhaust insertion tube 711 are connected to the interior of the sewage tank 7. When the sewage tank 7 covered with the sewage tank cover 71 is located at the opening at the lower end of the handle shell 61, the sewage insertion tube 712 is inserted into the sewage inlet hole 624 and the exhaust insertion tube 711 is inserted into the exhaust inlet hole 623.

[0027] Reference Figures 3 to 17 The flat mop head includes a mop head body 1, a foam substrate 2, and a cleaning component 52. The foam substrate 2 and the cleaning component 52 are stacked and attached to the bottom of the mop head body 1 from top to bottom (i.e., the foam substrate 2 is located between the cleaning component 52 and the mop head body 1). The mop head body 1 has a separate clean water chamber 15 and a wastewater chamber 14. The clean water chamber 15 provides clean water to the cleaning component 52 through a clean water channel. A wastewater platform 131 protrudes from the bottom of the mop head body 1. The platform 131 passes through the foam substrate 2. A water absorption groove 133 is provided on the bottom end face of the wastewater platform 131. The cleaning component 52 covers the opening of the water absorption groove 133, and the edge of the opening of the water absorption groove 133 presses against the cleaning component 52 to form a water absorption cavity 16. The water absorption groove 133 is provided with a water absorption hole 132 and a plurality of protrusions 1321 for preventing the water absorption hole 132 from being blocked. The wastewater cavity 14 is connected to the water absorption cavity 16 through the water absorption hole 132 to suck up the wastewater on the cleaning component 52 with negative pressure.

[0028] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 16 and Figure 17Inside the tractor body 1, the position of the water suction chamber 16 is opposite to the position of the sewage chamber 14. The sewage chamber 14 and the clean water chamber 15 are independently separated. The sewage chamber 14 is connected to the water suction chamber 16 through the water suction hole 132. In this invention, there are two sewage chambers 14, which are spaced apart. There are also two water suction chambers 16, which are arranged directly below the two sewage chambers 14. There is one clean water chamber 15, which is located between the two sewage chambers 14. Both the clean water chamber 15 and the sewage chamber 14 are elongated and are arranged along the length of the tractor body 1. Specifically, the tractor body 1 includes a tractor body 13, a clean water cover 12, and two sewage covers 11. The tractor body 13 is a rectangular plate, and two sewage platforms protrude from the bottom of the tractor body 13. 131, each wastewater platform 131 is a long trapezoidal shape and is set along the length of the mop head body 1. Multiple long, narrow suction grooves 133 are spaced apart along the length of the bottom end face of each wastewater platform 131. Each suction groove 133 is elliptical racetrack-shaped. Each suction groove 133 has a suction hole 132 and multiple protrusions 1321. Within the same suction groove 133, the suction hole 132 and all protrusions 1321 are located on the inner top wall of the suction groove 133, and all protrusions 1321 are arranged in a ring around the suction hole 132. The height of all protrusions 1321 is less than the depth of the suction groove 133 to prevent the cleaning component 52 from blocking the suction hole 132 under negative pressure. The top end face of the mop body 13 is positioned opposite to the two wastewater platforms 131. Each of the following structures has a concave, trapezoidal top groove 136 formed according to the shape of the sewage platform 131. Each top groove 136 has a sewage trough 137 at its bottom. The same sewage trough 137 is connected to multiple suction troughs 133 via multiple suction holes 132. Two elongated sewage covers 11 are respectively placed over the two sewage troughs 137 to form two sewage chambers 14. Each sewage cover 11 has a sewage connector 111 for connecting to a branch sewage pipe 113. The two branch sewage pipes 113 are connected to a combined sewage pipe 112 via a T-joint 114, allowing the combined sewage pipe 112 to connect to the sewage tank 7 on the handle assembly 63. A long, narrow clean water trough 138 is provided along the length of the top end face of the tow body 13. The water tank 138 is located between two top tanks 136. Multiple water holes 134 are spaced along the length of the water tank 138. The water cover 12 is elongated and covers the water tank 138, forming an elongated water cavity 15. A water connector 121 is provided on the water cover 12, which connects to a water pipe 122. The upper end of the water pipe 122 can communicate with the water tank 8 on the mop handle. An upper air hole 139 is also provided through the mop body 13. An exhaust connector 17 is connected to the top of the upper air hole 139 and is used to connect to an exhaust pipe 171. The lower end of the exhaust pipe 171 passes through the hinge of the handle assembly 63 and is located inside the flat mop head. The upper end of the exhaust pipe 171 is located inside the handle housing 61.The top of the vent pipe 171 is inserted into the base 62 and connected to the vent hole 623 on the base 62. When the sewage tank 7, covered by the sewage tank cover 71, is located at the opening at the lower end of the handle housing 61, the top of the vent pipe 711 is inserted into the vent hole 623, connecting the water outlet chamber 241 inside the flatbed tractor head with the sewage tank 7.

[0029] Reference Figure 7 , Figure 8 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17The foam substrate 2 is rectangular and made of EVA foam. Multiple water outlet holes 21, two through holes 221, and a vent 26 are provided on the foam substrate 2. The multiple water outlet holes 21 are arranged in a row at intervals between the two through holes 221. The positions of these water outlet holes 21 correspond one-to-one with the positions of multiple clean water holes 134 and are interconnected to form multiple clean water channels. Clean water in the clean water chamber 15 can provide clean water to the cleaning component 52 through the multiple clean water channels. The positions of the two through holes 221 are opposite to the positions of the two wastewater platforms 131. Each through hole 221 is elongated and arranged along the length of the foam substrate 2. The two wastewater platforms at the bottom of the drag body 13... Water platforms 131 pass through two through holes 221 on the foam substrate 2, respectively, so that the side wall of the water absorption groove 133 at the bottom of each wastewater platform 131 can extend to the outside of the foam substrate 2. The position of the lower air hole 26 corresponds to the position of the upper air hole 139. The lower air hole 26 and the upper air hole 139 are connected to form the exhaust channel. The exhaust channel is located between the water absorption hole 132 and the clean water channel. The bottom of the foam substrate 2 is recessed to form a groove 24. The lower air hole 26 is located in the groove 24. The cleaning component 52 is placed on the opening of the groove 24 to form a water outlet cavity 241. The water outlet cavity 241 is connected to the clean water cavity 15 through the clean water channel. The foam substrate 2 has a groove 24 at the bottom that is arranged in a circle around the two water absorption chambers 16. This groove connects to the wastewater tank 7 outside the flatbed head via an exhaust channel and an exhaust pipe 171, allowing gas in the wastewater tank 7 to be discharged to the water outlet chamber 241. When the wastewater tank 7 is full and not emptied in time (users usually empty the tank promptly when it is full, so the probability of it being full is low), water at the top of the tank can flow back into the groove 24, preventing wastewater from overflowing from the handle and reducing the user experience. Two dispensing platforms 22 protrude from the inner top wall of the groove 24 along the edges of the two through holes 221, with each dispensing platform 22 surrounding the corresponding wastewater platform 131. Multiple water-absorbing grooves 133 are arranged in a circle to surround multiple water-absorbing chambers 16 at the same wastewater platform 131, thus separating these water-absorbing chambers 16 from the clean water outlet area. The gap 222 of the wastewater absorption area is opened in the width direction of the dispensing platform 22. Preferably, there are two venting grooves 23. The two venting grooves 23 are located at the left and right ends of the foam substrate 2, respectively. The left venting groove 23 is located at the bottom left end of the foam substrate 2 and in the groove 24, and the right venting groove 23 is located at the bottom right end of the foam substrate 2 and in the groove 24. In this embodiment, the shape of the venting groove 23 is non-linear, and the gas in the water outlet chamber 241 can be discharged to the outside of the mop through the two venting grooves 23.

[0030] Reference Figure 7 and Figure 8The cleaning component 52 includes an absorbent cloth strip 5 and a mop 3. The absorbent cloth strip 5 and the mop 3 are sequentially attached to the bottom of the foam substrate 2 from top to bottom. The absorbent cloth strip 5 is a high-density water-locking cloth, and the water absorption rate of the absorbent cloth strip 5 is greater than that of the mop 3. Water inlet holes 51 are provided on the absorbent cloth strip 5 at positions opposite to each water absorption cavity 16. The diameter of these water inlet holes 51 is larger than the fabric gap of the absorbent cloth strip 5 (i.e., the gap formed by the intersection of the warp and weft threads of the fabric itself). The sewage on the mop 3 can enter each water absorption cavity 16 through multiple water inlet holes 51. Since the opening edge of the water absorption groove 133 (i.e., the side wall) protrudes relative to the other bottom surfaces of the foam substrate 2, it will interfere with the absorbent cloth strip 5. Therefore, the side wall of the water absorption groove 133 presses against the absorbent cloth strip 5 to form the water absorption cavity 16.

[0031] Reference Figure 13 , Figure 14 , Figure 16 and Figure 17 In this invention, when the absorbent cloth strip 5 covers the bottom of the foam substrate 2, the area opposite to the absorbent cavity 16 in the gap formed between the foam substrate 2 and the absorbent cloth strip 5 is the dirt absorption area, and the area opposite to each water outlet 21 is the clean water outlet area. The absorbent cloth strip 5 covers the groove 24 at the bottom of the foam substrate 2 to form a water outlet cavity 241. The two dispensing platforms 22 of the foam substrate 2 form an inner isolation layer 31 between themselves and the absorbent cloth strip 5 of the cleaning component 52 through a dispensing process. The inner isolation layer 31 on the same dispensing platform 22 is arranged around all the absorbent cavities 16 on the corresponding wastewater platform 131 so as to absorb the wastewater. The sludge-absorbing area and the clean water-discharging area between the foam substrate 2 and the cleaning component 52 are sealed and separated. The gap 222 of the sludge-absorbing area is connected to the outside through the vent 23. Each dispensing station 22 is fixedly connected to the absorbent cloth strip 5 of the cleaning component 52 through the inner isolation layer 31 so as to seal and separate the sludge-absorbing area from the clean water-discharging area. The edge of the foam substrate 2 is fixedly connected to the edge of the absorbent cloth strip 5 of the cleaning component 52 through the dispensing process to form an annular outer isolation layer 32. The outer isolation layer 32 seals and separates the clean water-discharging area from the outside. During the use of the mop head of the present invention, the foam substrate 2 will be compressed and deformed to a certain extent.

[0032] Reference Figure 7 and Figure 8 The foam substrate 2 is detachably connected to the body 13 of the trolley head 1 via Velcro. The Velcro includes an upper Velcro 135 and a lower Velcro 25. The upper Velcro 135 is fixed to the bottom edge and middle of the body 13, and the lower Velcro 25 is fixedly connected to the top of the foam substrate 2 by sewing.

[0033] Reference Figures 5 to 9A cover 4 is fixedly connected to the top of the tractor body 1. The cover 4 is hinged to the handle assembly 63. The cover 4 covers the top of the tractor body 13 to form an inner cavity. The two branch sewage pipes 113, the three-way connector 114, the lower end of the exhaust pipe 171, the lower end of the combined sewage pipe 112, and the lower end of the clean water pipe 122 are all located in the inner cavity. The upper ends of the exhaust pipe 171, the combined sewage pipe 112, and the clean water pipe 122 all pass through the hinge of the cover 4 to the outside of the flatbed tractor. The clean water pipe 122 is connected to the clean water tank 8, and a clean water pump 91 is provided on the clean water pipe 122. The combined sewage pipe 112 and the exhaust pipe 171 are both connected to the sewage tank 7. A sewage pump 9 is provided on the combined sewage pipe 112. The sewage pump 9 is a peristaltic pump or a diaphragm pump.

[0034] Reference Figures 1 to 13 The present invention provides a cleaning method for separating clean and dirty parts in a flat mop, comprising the following steps: Clean water supply: The clean water pump 91 in the handle assembly 63 draws clean water from the clean water tank 8 on the handle assembly 63 and delivers it to the clean water chamber 15 in the center of the flat mop head. The clean water in the clean water chamber 15 is diverted through multiple clean water channels and then converges into the water outlet chamber 241 of the flat mop head. It is then absorbed by the absorbent strip 5 of the flat mop head and then permeates into the mop cloth 3 of the flat mop head, providing a quantitative amount of clean water to the center of the cleaning surface of the flat mop head along its length. Wastewater discharge: During the cleaning process, wastewater from the ground enters from both the front and rear ends of the flat mop head. It is absorbed by the mop cloth 3 and absorbent strip 5 of the flat mop head in sequence. Then, the wastewater pump 9 in the handle assembly 63 vacuums the wastewater. The wastewater absorbed by the front end of the absorbent strip 5 is sucked into the various suction chambers 16 at the front end of the flat mop head. The wastewater absorbed by the rear end of the absorbent strip 5 is sucked into the various suction chambers 16 at the rear end of the flat mop head. Then, the wastewater in the suction chambers 16 at both ends merges through the suction hole 132 and enters the two wastewater chambers 14. Finally, the water in the two wastewater chambers 14 merges through the waste pipe and is sucked into the wastewater tank 7 on the handle assembly 63, thus sucking out the wastewater from both the front and rear ends of the flat mop head. Venting: The gas in the sewage tank 7 is discharged into the water outlet chamber 241 of the flat mop head through the vent pipe 171, and the gas in the water outlet chamber 241 is discharged to the outside of the flat mop through the two vent slots 23.

[0035] The present invention provides a cleaning method for separating clean and dirty water in a flat mop. By optimizing the paths and mechanisms of clean water supply and wastewater discharge, it achieves a quantitative supply of clean water to the center of the cleaning surface along the length of the flat mop head, and efficient and thorough discharge of wastewater from the side of the flat mop head. This achieves cleaning by separating clean and dirty water, while improving the synergy between the clean water supply system and the wastewater discharge system. It has the advantages of simple structure, convenient operation, and good cleaning effect, and can improve the cleaning effect, efficiency, and hygiene of the flat mop.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Therefore, any equivalent variations made in accordance with the scope of the patent application of the present invention are still within the scope of the present invention.
