Description

Technical Field

[0001] This utility model relates to the field of mops, specifically to a flat mop that sprays liquid for cleaning. Background Technology

[0002] Hands-free mops are cleaning components that use a wringing mechanism to wash and wring out the mop head. They are widely popular because they eliminate the need to remove the mop head from the mop for washing.

[0003] However, in actual use, the mop cloth can not be cleaned by simply washing it with water from a tap or bucket. To clean it more thoroughly, a cleaning agent needs to be added to the mop cloth.

[0004] For example, Chinese patent CN202122497931.5 relates to a hands-free water-spraying mop. The mop has a liquid storage unit on a fixed unit, a water outlet fixed to a scraper base, and the water outlet of the water outlet base corresponds to the scraper. The scraper has holes corresponding to the water outlet. The actuation unit controls the spraying unit to spray the liquid from the liquid storage unit from the water outlet and the holes. The cleaning unit can clean the scraper when it passes through it.

[0005] For example, Chinese patent CN202323668799.5 relates to a flat mop. The flat mop has a rinsing frame with a rinsing port corresponding to the mop head. The rinsing frame has a pump assembly inside. The rinsing port has a water outlet on the side facing the cleaning surface of the mop head. The liquid storage tank and the pump assembly are both located on the rinsing frame. The pump assembly is connected to the water outlet and the liquid storage tank pipes respectively. The pump assembly can draw liquid from the liquid storage tank and drive the liquid to be discharged through the water outlet to the cleaning surface of the mop head.

[0006] The aforementioned mops all use a water outlet on the wringer and a pump unit at the mounting point to spray cleaning liquid onto the object being wiped. The wringer and guide sections require separate spaces to install the individual spray components, resulting in a complex structure and cumbersome installation. Furthermore, factory testing of the spray component's function requires inspecting the entire wringer and spray assembly, leading to low testing efficiency. If the test fails, disassembling and reassembling the wringer and spray components is also quite troublesome. Therefore, the structure of the spray component on the mop needs further optimization. Utility Model Content

[0007] One objective of this invention is to provide a spray-cleaning flat mop that solves the aforementioned problems.

[0008] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions:

[0009] A flat mop for spray cleaning includes a mop head and a mop handle rotatably connected. The mop head is provided with a wiping agent, and the mop handle is provided with a wringing device that can move up and down. The wringing device includes a wringing sleeve and a wringing frame. The wringing frame is provided with a squeezer for cleaning the wiping agent. The mop handle is provided with a positioning mechanism, which includes a driving member and a limiting member. The limiting member can prevent the wringing device from moving downward. The wringing sleeve is provided with a spraying mechanism, which includes a liquid storage chamber, a spray nozzle, and a pressing part. The pressing part is used to drive the liquid in the liquid storage chamber. The liquid is sprayed out through the nozzle, which is located above one side of the object being wiped. The pressing part is located on the side of the wringer sleeve away from the wringer frame. In use, the mop head rotates to a position parallel to the mop handle and controls the movement of the drive component. The drive component drives the limiting component to move and release the limiting of the wringer. The mop head enters the wringer frame, and a spray area is formed between the nozzle and the object being wiped. The nozzle sprays cleaning liquid onto the object being wiped. The wringer frame moves up and down to squeeze and spread the cleaning liquid evenly on the object being wiped to clean it. By integrating the spray mechanism onto the wringer sleeve, users can simultaneously control both the wringer's movement and the spraying function with one hand, making operation more convenient. The spray zone design allows the cleaning liquid sprayed by the spray mechanism to first move into the spray area, enabling users to observe the spray pattern and easily adjust the spray size or replenish the storage chamber. The positioning mechanism positions the wringer on the mop handle, preventing it from moving downwards during mopping and affecting the rotation of the mop handle and head. When cleaning the mop head, once the mop head rotates to a parallel cleaning position, the drive mechanism activates the limiting mechanism to release the limit, allowing the wringer to move freely up and down to clean the mop head. The positioning and unlocking of the positioning mechanism does not require a separate switch, further enhancing ease of use.

[0010] Preferably, the positioning mechanism further includes a rotating shaft and an elastic element. The driving element and the limiting element are rotatably mounted inside the mop handle via the rotating shaft. The elastic element keeps both the driving element and the limiting element extended from the mop handle. The limiting element provides upward support and limitation for the wringing device. The driving element waits for the mop head to rotate to achieve linkage. The limiting element limits the wringing device vertically by supporting it from below. The rotation of the mop head cooperates with the driving element extending from the mop handle, causing the driving element to rotate inward into the mop handle and simultaneously driving the limiting element to rotate inward into the mop handle to retract and release the limiting of the wringing device. During the mop head cleaning process, the relative position between the mop head and the driving element is fixed, and the mop head always prevents the driving element and the limiting element from rotating outward.

[0011] Preferably, the positioning mechanism further includes a left cover and a right cover, which are fixedly connected and clamp the driving member and the limiting member. The left cover has a first groove, and the right cover has a second groove. The first groove and the second groove together form a cavity for fixing and installing the nut. The mop handle is provided with an anti-rotation member, which prevents the wringing device from rotating relative to the mop handle. A screw passes through the anti-rotation member and the mop handle from the outside until it engages with the nut and is tightened, fixing the positioning mechanism and the anti-rotation member in a preset position on the mop handle. The positioning mechanism is pre-installed as a module, optimizing the installation procedure. It eliminates the need to individually insert each component of the positioning mechanism into the mop handle for installation. At the same time, fixing the positioning mechanism and the anti-rotation member with the same screw reduces the number of screws, and the cap of the screw does not protrude from the outer surface of the mop handle.

[0012] Preferably, the spray nozzle extends towards the wringer, and sprays liquid parallel to or at an angle towards the object being wiped. The spray nozzle is positioned so as not to contact the object being wiped, preventing dirt on the object from clogging the nozzle.

[0013] Preferably, the spraying mechanism further includes a housing, in which the liquid storage chamber is provided. The spray nozzle is connected to the liquid storage chamber via a liquid pump or directly. The pressing part presses the liquid pump to spray liquid, or the pressing part presses to change the air pressure in the liquid storage chamber, causing the cleaning liquid in the liquid storage chamber to be sprayed out from the spray nozzle.

[0014] Preferably, the housing includes a front shell and a rear shell that overlap each other. A partition is integrally formed on the rear shell, which divides the housing into left and right parts. The left part of the housing forms the liquid storage chamber, and the right part of the housing forms a structure for installing the pressing part and the liquid pump. The liquid pump has an inlet and an outlet. The inlet communicates with the liquid storage chamber, and the outlet is connected to the spray nozzle through an outlet pipe.

[0015] Preferably, the middle part of the partition extends into the liquid storage cavity to form a pump housing integrally formed with the rear shell, and the pump housing has the liquid inlet and liquid outlet opening into the liquid storage cavity.

[0016] Preferably, the pump further includes a pump core, which is movably installed inside the pump housing. The outer end of the pump core extends out of the pump housing to form a pressing part or cooperates with the pressing part. The inlet is connected to the inlet pipeline through an inlet valve, and the outlet is connected to the outlet pipeline through an outlet valve. The inlet pipeline extends to the end of the storage chamber.

[0017] Preferably, the front shell is provided with a reinforcing ring. When the front shell and the rear shell are installed, the reinforcing ring is inserted into the rear shell and adapted to the surface of the rear shell. The installed front shell and the rear shell have two sets of vertical mating surfaces, and the two sets of mating surfaces work together to seal the liquid storage cavity.

[0018] Preferably, the front surface of the wringer is provided with a return hole, which connects the inside and outside of the wringer. The cleaning liquid sprayed onto the wringer by the spraying mechanism can flow through the return hole onto the wiping material passing through the wringer.

[0019] The advantages of this utility model are:

[0020] The positioning mechanism positions the wringer on the mop handle, preventing it from moving downwards during mopping and affecting the rotation of the mop handle and head. When cleaning the mop head, the mop head rotates to a parallel cleaning state, and the limiter is released by the drive component, allowing the wringer to move freely up and down to clean the mop head. The positioning and unlocking of the positioning mechanism do not require a separate switch, making it more convenient to use.

[0021] The upper and lower ends of the wringing sleeve are respectively equipped with a spraying mechanism and a wringing frame, making the spraying mechanism and the wringing frame independent in function and structure. This simplifies the installation structure of the wringing device, eliminating the need to set up space on the wringing sleeve and wringing frame to install the control and water circuit structure of the spraying mechanism. By setting the spraying mechanism on the wringing sleeve, the user can simultaneously control the movement and cleaning of the wringing device and the spraying function of the spraying mechanism with one hand, making operation more convenient.

[0022] The spray zone is designed so that the cleaning liquid sprayed by the spraying mechanism first moves into the space of the spray zone, allowing the user to observe the spraying status and easily adjust the spray size or replenish the cleaning liquid in the storage chamber.

[0023] Even if a small portion of the cleaning fluid sprayed by the spraying mechanism is sprayed onto the wringer, or if the cleaning fluid on the wiped item adheres to the wringer during the relative movement of the wiped item and the wringer, the cleaning fluid on the wringer can flow back to the wiped item through the return hole along the surface of the wringer or along the squeezer for cleaning. External cleaning water can also enter the wringer through the return hole to clean the wringer and the wiped item. Attached Figure Description

[0056] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0057] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0058] like Figure 1-32 A flat mop for spray cleaning includes a mop handle 1 and a mop head 2 rotatably connected. The mop head 2 is provided with a wiping material 3. The mop handle 1 is provided with a wringing device 4 that can move up and down. The wringing device 4 includes a wringing sleeve 5, a wringing frame 6 and a spraying mechanism 7. The wringing frame 6 is provided with a squeezer 8 for cleaning the wiping material 3. When the mop head 2 is rotated to a direction that is approximately parallel to the mop handle 1, the wringing device 4 moves up and down along the mop handle 1 to a preset position. The spraying mechanism 7 can spray cleaning liquid onto the wiping material 3. The squeezer 8 moves with the wringing device 4 to clean the wiping material 3.

[0059] The connection structure between the mop handle 1 and the mop head 2 in this utility model adopts a common connection structure in the prior art. The patent document with publication number CN208355360U discloses the technical features of the mop handle and the mop head, that is, the mop handle and the mop head are connected by a steering mechanism. Through the steering mechanism, the mop head can move freely in front, back, left and right relative to the mop handle. The steering mechanism can also keep the mop head and the mop handle in a vertical and parallel position. This utility model will not elaborate on the connection structure between the mop handle and the mop head.

[0060] In this utility model, the cleaning liquid sprayed by the spraying mechanism 7 is a general term and does not specifically refer to ordinary cleaning liquid. It can be a cleaning liquid such as dish soap, hand soap, or laundry detergent that is used to directly clean items or is used in combination with water to clean items. It can also be a liquid used for sterilization and disinfection such as alcohol or disinfectant. It can also be a liquid used to remove odors or add fragrance. Of course, it can also be ordinary water. By spraying water, the moisture of the wiping object 3 or the ground is increased. All of the above liquids can be sprayed on the wiping object 3 or the ground to improve the cleaning effect of the wiping object 3 or the ground.

[0061] The water-squeezing device 4 in this utility model includes a water-squeezing sleeve 5, a water-squeezing frame 6, and a spraying mechanism 7, specifically, as follows: Figure 2 The top of the wringer sleeve 5 is a tube sleeve that can be fitted onto the outer surface of the mop handle 1 and move up and down along the mop handle 1. The bottom of the wringer sleeve 5 is fixedly connected to the wringer frame 6. The lower end of the wringer sleeve 5 can also be a tube sleeve fitted onto the outer surface of the mop handle 1. Figure 3 The lower end of the wringer sleeve 5 can also be a connecting rod 9 extending vertically and vertically outside the mop handle 1. For example... Figure 4 The wringer 6 has a squeezing port 10 and a rod opening 11 that run vertically through the mop head 2 and the rod opening 11. The squeezing port 10 and the rod opening 11 are connected laterally. The squeezing port 10 is used for the mop head 2 and the cleaning material 3 to pass through vertically during cleaning. The rod opening 11 is sleeved on the outer surface of the mop handle 1. During the process of the mop head 2 and the cleaning material 3 entering the squeezing port 10, the front and rear sides of the wringer 6 can simultaneously support the mop handle 1, the mop head 2 and the cleaning material 3. The upper end of the wringer 6 is fixedly connected to the lower end of the wringer sleeve 5 to form an integral wringer device 4.

[0062] In this utility model, the spraying mechanism 7 includes a pressing part 12, a liquid storage chamber 13, and a spray nozzle 14. The liquid storage chamber 13 is used to store cleaning liquid. The pressing part 12 is used to control the cleaning liquid to be sprayed out from the spray nozzle 14 and sprayed onto the wiping object 3 or the ground. The upper end of the wringing sleeve 5 forms a wringing handle 15 for the user to hold and push and pull the wringing device 4 up and down. The spraying mechanism 7 is installed on the wringing handle 15 or the wringing sleeve 5 is located below the wringing handle 15, providing a space for the user's hand to hold. When cleaning the wiping object 3 with a flat mop, one hand is generally held on the upper end of the mop handle 1, and the other hand is held on the wringing handle 15. The wringing handle 15 is pushed and pulled up and down to realize the relative movement and cleaning between the wringing device 4 and the wiping object 3. The position of the spray mechanism 7 makes it convenient for the user to hold the wringer handle 15 and push and pull the wringer device 4 to clean the wiping object 3. At the same time, the user can control the spray mechanism 7 to spray cleaning liquid onto the wiping object 3 to further clean or wet the wiping object 3, thereby realizing one-handed operation to spray liquid onto the wiping object 3 and clean the wiping object 3 at the same time.

[0063] The specific usage method is as follows, such as Figure 5The wringing device 4 is positioned at the high position of the mop handle 1. The mop head 2 is rotated to a position perpendicular or inclined to the mop handle 1. At this time, the flat mop can be used to clean the floor. When the mop head 2 is rotated to a position approximately parallel to the mop handle 1, the wringing device 4 is pushed downwards. The mop head 2 and the wiping material 3 enter the squeezing port 10 upwards. The squeezer 8 cleans the wiping material 3. At the same time, the pressing part 12 is operated to spray cleaning liquid onto the wiping material 3 to improve the cleaning effect.

[0064] In this invention, the direction facing the wiping object 3 is the forward direction, and the direction away from the wiping object 3 is the rear direction. The squeezer 8 and the spray nozzle 14 are both located in front of the squeezing device 4. Preferably, when the wiping object 3 is parallel to the mop handle 1, the squeezer 8 and the spray nozzle 14 are both located in front of the wiping object 3, so that the squeezer 8 can contact the wiping object 3 for cleaning and squeezing, and the moving resistance between the squeezer 8 and the wiping object 3 will not be too large, and it can also provide space for the spray nozzle 14 to spray liquid onto the wiping object 3. Example 1

[0065] In this embodiment, the wringer sleeve 5 and the main body of the wringer frame 6 are integrally molded from plastic material. The lower end of the wringer sleeve 5 is provided with a clearance groove 16 for the mop head 2 to move. The main body of the wringer frame 6 is equipped with a squeezer 8 and a support 17 to jointly hold the mop head 2. The mop handle 1 and the mop head 2 can pass through the handle opening 11 and the squeezing opening 10 at the same time. The squeezer 8 cleans or squeezes water from the wiping material 3 that enters the squeezing opening 10.

[0066] In this embodiment, as Figure 7 The spraying mechanism 7 includes a housing 18, which has a cavity to form a liquid storage chamber 13 or a liquid storage chamber 13 installed inside the housing 18. The pressing part 12 and the spray nozzle 14 are also provided on the housing 18, so that the housing 18, the pressing part 12, the liquid storage chamber 13 and the spray nozzle 14 form a spraying module as a whole. The pressing part 12 can be installed on the liquid storage chamber 13 and then installed on the housing 18 at the same time as the liquid storage chamber 13. The spray nozzle 14 can be a separate component or a spraying port can be provided on the housing 18. The squeezing sleeve 5 has an installation platform 19 on or below the squeezing handle 15. The spraying mechanism 7 is installed on the squeezing sleeve 5 through the installation platform 19.

[0067] Preferably, to facilitate the inspection and replacement of the spraying mechanism 7, during production and installation, the pressing part 12, the liquid storage chamber 13, the spray nozzle 14, and the housing 18 are assembled into a complete spraying module, which is then installed on the mounting platform 19. Since each spraying mechanism 7 needs to be inspected during production assembly or inspection, the qualified spraying mechanism 7 can be installed on the mounting platform 19, while the unqualified spraying mechanism 7 needs to be repaired or destroyed. With a complete spraying module setup, the spraying module can be inspected individually. In the prior art, the spraying mechanism is associated with the squeezing device; that is, some components of the squeezing device form some components of the spraying mechanism. During production and inspection, the entire squeezing device, or even the entire flat mop, needs to be inspected for spraying. Because the components to be inspected are large, the inspection is cumbersome and inefficient. Compared with the spraying mechanisms in the prior art, the assembly, inspection, and repair of the spraying mechanism 7 and the squeezing device 4 in this embodiment are simpler and less costly.

[0068] In this embodiment, as Figure 2 and Figure 5 The spraying mechanism 7 and the wringer 6 are independent, including functional independence and structural independence. Functional independence means that the spraying function of the spraying mechanism 7 and the cleaning and wringing function of the wringer 6 are independent. Regardless of whether the spraying mechanism 7 and the wringer 4 are installed as a whole, the spraying function of the spraying mechanism 7 and the wringing function of the wringer 6 can be realized independently. Preferably, the spraying mechanism 7 is detachably installed on the wringer sleeve 5. When the spraying mechanism 7 is installed on the wringer sleeve 5, the flat mop can simultaneously have the functions of spraying liquid and cleaning and wringing liquid on the wiping object 3. When the spraying mechanism 7 is removed, the flat mop still has the functions of cleaning and wringing liquid on the wiping object 3, and the removed spraying mechanism 7 can still be used as a spray bottle to spray liquid on other items.

[0069] like Figure 5 Structurally independent, the spraying mechanism 7 and the squeezing frame 6 are not connected except for the squeezing sleeve 5. The spraying mechanism 7 is located directly above the squeezer 8, and there is no water circuit connection or control connection between the spraying mechanism 7 and the squeezing frame 6. There is a gap between the spraying mechanism 7 and the squeezing frame 6 or between the spray nozzle 14 and the squeezing frame 6, which forms the spraying area 20.

[0070] In the above embodiments, such as Figure 5The housing 18 extends towards the wringer 6, and the spray nozzle 14 is located at the end of the housing extension. The housing extension forms a liquid storage chamber 13. That is, the spray direction of the spray nozzle 14 is approximately parallel to the extension direction of the mop handle 1. When the wringer 4 moves downward along the mop handle 1, the mop head 2 and the wiping material 3 move upward relative to each other. The wiping material 3 passes upward through the squeezing port 10 and enters the spray area 20 until it moves to a height where the bottom of the spray mechanism 7 is close to or at least partially overlaps with the top of the wiping material 3. During the process of the wiping material 3 entering and leaving the spray area 20, or when the wiping material 3 moves to the preset highest position, the pressing part 12 controls the spray nozzle 14 to spray cleaning liquid onto the spray area 20 for the wiping material 3 to self-clean.

[0071] When cleaning the object 3 with a regular flat mop, the object 3 is usually facing upwards towards the faucet. Based on this usage habit, the spray nozzle 14 in this embodiment is set out in an exposed position and is not in contact with the object 3. The cleaning liquid can fall onto the object 3 under the action of the spray force and gravity.

[0072] like Figure 6 To prevent users from accidentally pressing the pressing part 12 or spraying the liquid when the wiping object 3 is facing down, thus preventing the cleaning liquid from being sprayed onto the wiping object 3, the spray nozzle 14 can be tilted so that the cleaning liquid can still move onto the wiping object 3 by its inertia after leaving the spray nozzle 14. This ensures that the cleaning liquid can be sprayed onto the wiping object 3 no matter what angle the flat mop is controlled at.

[0073] Compared to the method where the spray nozzle 14 is positioned to adhere to or contact the wiping object 3, in this embodiment, the cleaning fluid passes through the outside air after leaving the spray nozzle 14 before falling onto the wiping object 3. Whether the spraying mechanism 7 sprays fluid and the amount of fluid sprayed can be observed through the movement of the cleaning fluid in the outside air and its falling onto the wiping object 3, allowing the user to adjust the spray size of the spraying mechanism 7 and replenish the cleaning fluid in the reservoir 13. Meanwhile, the method where the spray nozzle 14 contacts the wiping object 3 for spraying means that dust and dirt on the wiping object 3 can easily clog the spray nozzle 14, affecting the spraying effect.

[0074] To illustrate the independent operation of the spraying mechanism 7 and the water-squeezing frame 6, and the position of the spray zone 20, as follows: Figure 5 and Figure 8The length of the wringing device 4 is X, the length of the mop head 2 or the wiping object 3 is Y, and the distance between the spray nozzle 14 and the wringing rack 6 is Z. This distance Z forms the spray area 20, which is used for the movement of the cleaning solution during spraying and for the user to observe the spraying process. Length X is greater than length Y to prevent the hand from contacting the wiping object 3 during the wringing device 4's movement. To prevent the sprayed cleaning solution from falling onto the wringing rack 6 or even over the rack and onto the ground, in this embodiment, length Z is set to be greater than half the length Y. In this embodiment, lengths X, Y, and Z are all greater than... Figure 8 The horizontal length of the flat mop in its current state is shown. It should be noted that if the wringing device 4, mop head 2, and wiping material 3 are adjustable in length or foldable, only the lengths of the wringing device 4, mop head 2, and wiping material 3 under normal cleaning and wringing conditions are compared. The length Z generally refers to the distance between the top of the wringing frame 6 (excluding the wringing sleeve 5) and the part of the spray mechanism 7 closest to the wringing frame 6. If most of the parts of the wringing device 4 are located above the wringing sleeve 5 and the spray nozzle 14 is located inside the wringing frame 6, then the length Z is zero or even a negative value.

[0075] In the above embodiments, when the wringing device 4 moves to its lowest position relative to the mop head 2, that is, when the mop head 2 and the wiping material 3 move upward to their highest position, the spraying mechanism 7 and the wiping material 3 have an overlapping area on a plane perpendicular to the mop handle 1, or the two never overlap, such as... Figure 5 and Figure 8 These are schematic diagrams showing the overlapping areas between the spraying mechanism 7 and the wiping material 3, and the non-overlapping areas, respectively.

[0076] In other embodiments, the spray nozzle 14 can also be positioned on the side of the housing 18 close to the object being wiped 3. When the spray nozzle 14 moves with the wringing device 4 to any position overlapping with the object being wiped 3, the spray nozzle 14 sprays liquid onto the object being wiped 3. In this spraying method, a gap needs to be provided between the wringing sleeve 5 and the spraying mechanism 7 to allow the mop head 2 and the object being wiped 3 to enter. This gap forms a spray area 20. The thickness of the spray area 20 is adapted to the thickness of the mop head 2 plus the object being wiped 3. When the spray nozzle 14 partially overlaps with the object being wiped 3, the spray nozzle 14 is either attached to the object being wiped 3 or there is a spray gap between the spray nozzle 14 and the object being wiped 3. In this spraying method, the area where the wiping object 3 can be sprayed is related to the overlapping length of the movement of the wiping object 3 and the spray nozzle 14, and the width of the spray nozzle 14. If there is an area where the cleaning liquid has not been sprayed, the squeezer 8 moves relative to the wiping object 3 to spread the cleaning liquid evenly and bring it to the area where the cleaning liquid has not been sprayed, so that the wiping object 3 can receive the cleaning liquid as a whole.

[0077] Compared with existing spraying mechanisms, the spraying mechanism 7 in this embodiment is more integrated and simpler. There is no need to set up separate cavities in the squeezing sleeve 5 and squeezing frame 6 for installing water channels, thereby simplifying the installation structure of the squeezing device 4 and the spraying mechanism 7 and improving production assembly efficiency. At the same time, the water channels of the spraying mechanism 7 are independent of the squeezing sleeve 5 and squeezing frame 6, which can avoid the water channels in the squeezing sleeve 5 and squeezing frame 6 from being bent or blocked due to pressure and tension caused by the up and down movement of the squeezing device 4. Of course, after the spraying mechanism 7 in this embodiment is set as an independent spraying module, it can also be used without setting up water channels, and the cleaning liquid can be sprayed directly from the liquid storage chamber 13 through the spray nozzle 14.

[0078] In the above embodiment, the wringer 6 located on the front side of the squeezing port 10 has a certain thickness. This thickness can increase the overall strength of the wringer 6 and prevent the wringer 6 from deforming when the mop head 2 and the wiping material 3 enter the squeezing port 10. The space formed by the thickness of the front side of the wringer 6 can also be used to install the squeezer 8.

[0079] Preferably, the front side of the wringer 6 is provided with an intercepting part 21. The intercepting part 21 extends forward and can block the liquid about to leave the wiping material 3, preventing the liquid from moving to the ground, walls, or other places where the liquid is not needed. In this embodiment, the intercepting part 21 is perpendicular to the wiping material 3 during wringing or is inclined with the front end higher than the rear end. If the intercepting part 21 is set with the front end lower than the rear end, regardless of whether the inclined surface is straight or curved, the cleaning liquid can easily be guided to move outward along the extension direction of the intercepting part 21. The intercepting part 21 in this embodiment can adopt the following methods:

[0080] The first type: such as Figure 9 An intercepting part 21 is located on the front exterior of the wringer 6, i.e., a raised protrusion is provided in front of the wringer 6. The area at the angle between the surfaces of the intercepting part 21 and the wringer 6 forms a temporary storage area 22. The intercepting part 21 can also be configured to be perpendicular or inclined to the wiping material 3. In order to prevent the liquid in the temporary storage area 22 from flowing out and to be used for cleaning the wiping material 3, a return hole 23 can be provided at any one or more of the three positions: the intercepting part 21, the wringer 6, and the area between the intercepting part 21 and the wringer 6. The liquid in the temporary storage area 22 can flow into the squeezing port 10 through the return hole 23 to clean the wringer 6, the squeezer 8, or the wiping material 3. External cleaning water can also enter the wringer 6 through the return hole 23 to clean the wringer 6, the squeezer 8, or the wiping material 3.

[0081] The second type: such as Figure 10The intercepting part 21 is located at the top of the front side of the wringer 6, or the top surface of the front side of the wringer 6 forms the intercepting part 21. The intercepting part 21 blocks part of the liquid and forms a temporary storage area 22 above the intercepting part 21. When the intercepting part 21 is inclined, the angled area between the intercepting part 21 and the wiping material 3 forms the temporary storage area 22. This temporary storage area 22 can intercept and store more liquid. In general use, the inclined intercepting part 21 is more vertical, and its guiding effect is better. Similarly, the intercepting part 21 can also be provided with a through-hole 23. The liquid in the temporary storage area 22 can flow into the squeezing port 10 or the wringer 6 through the through-hole 23 to clean the wiping material 3. External cleaning water can also enter the wringer 6 through the through-hole 23 to clean the wringer 6, the squeezer 8, or the wiping material 3.

[0082] The third type, such as Figure 11 Furthermore, by setting up the two types of interception units 21 mentioned above, the interception effect is improved.

[0083] Preferably, the interception section 21 adopts a flat surface or a rear end that is lower than the front end to improve the interception and diversion effect.

[0084] In the above embodiment, when the flat mop is washing and wringing out water, as the wringing device 4 moves downward relative to the wiping object 3, the squeezer 8 squeezes the wiping object 3, and the water in the wiping object 3 is driven downward by the squeezer 8. The wringing frame 6 is provided with a drain hole 24 below the interception part 21. The drain hole 24 and the return hole 23 are independent. The water generated by the squeezer 8 in cleaning and wringing out the wiping object 3 flows outward through the drain hole 24 and the squeeze port 10.

[0085] Specifically, such as Figure 12 The squeezer 8 is equipped with an inclined rail 25. Both ends of the squeezer 8 are movably mounted on the inclined rail 25 via protrusions 26. During washing or wringing, the squeezer 8 moves under the pressure of the wiping material 3 to adjust the tightness between the squeezer 8 and the wiping material 3. Figure 10 The squeezing device 4 moves downward, and the squeezer 8 moves towards the squeezing port 10, increasing the depth of interference between the squeezer 8 and the wiping material 3 to clean and squeeze out water from the wiping material 3; Figure 9 The squeezing device 4 moves upward, and the squeezer 8 moves away from the squeezing port 10. The interference depth between the squeezer 8 and the wiping material 3 becomes smaller, and the mop head 2 and the wiping material 3 pass through the squeezing port 10 with less effort.

[0086] In other embodiments, the squeezer 8 may be fixed to the water squeezing frame 6 or the activity state of the squeezer 8 may be reversed as described above. When the water squeezing device 4 moves upward, the squeezer 8 cleans and squeezes water from the wiping material 3. The water squeezed out of the wiping material 3 flows out through the return hole 23, so that the return hole 23 has the dual function of draining water outward and draining liquid inward under different usage conditions.

[0087] Preferably, the mop handle 1 is provided with a positioning mechanism, which includes a driving member 70 and a limiting member 71. The limiting member 71 can prevent the wringing device 4 from moving downward, thereby preventing the wringing device 4 from sliding down the mop handle 1 during the mopping process and affecting the mopping work.

[0088] Specifically, the driving component 70 and the limiting component 71 are installed inside the mop handle 1. The lower end of the mop handle 1 is provided with a hole for the driving component 70 and the limiting component 71 to extend out. The driving component 70 extends from the front side of the mop handle 1, and the limiting component 71 extends from the rear side of the mop handle 1. When mopping the floor, the mop head 2 rotates to an angle that is inclined or perpendicular to the mop handle 1. When cleaning the mop head 2, the mop head 2 rotates to an angle that is parallel to the mop handle 1. When the mop head 2 rotates to an angle that is parallel to the mop handle 1, the upper end of the mop head 2 contacts the extended driving component 70 and pushes the driving component 70 to move into the mop handle 1, thereby driving the limiting component 71 to move into the mop handle 1 to release the limiting of the wringing device 4. The wringing device 4 can move up and down to clean the mop head 2. The linkage between the drive component 70 and the limit component 71 eliminates the need for a separate switch to control the limit and unlock of the limit component 71. The movement control of the limit component 71 is achieved solely through the necessary actions of the mop head 2 during the cleaning process, making it more reasonable and convenient to use.

[0089] Preferably, the positioning mechanism further includes a rotating shaft 72, an elastic element 73, a left cover 74, and a right cover 75. The driving element 70 and the limiting element 71 are rotatably mounted inside the mop handle 1 via the rotating shaft 72. The elastic element 73 keeps the driving element 70 and the limiting element 71 in a state of extending out of the mop handle 1. The limiting element 71 provides upward support and limitation for the wringing device 4. The driving element 70 waits for the mop head 2 to rotate to form a linkage. The left cover 74 and the right cover 75 are fixedly connected and clamp the driving element 70 and the limiting element 71. The left cover 74 has a first groove 76, and the right cover 75 has a second groove 77. The first groove 76 and the second groove 77 together form a cavity to fix and install the nut 78. The mop handle 1 is provided with an anti-rotation element 79, which prevents the wringing device 4 from rotating relative to the mop handle 1. The screw passes through the anti-rotation element 79 and the mop handle 1 from the outside until it engages with the nut 78 and is tightened, fixing the positioning mechanism and the anti-rotation element 79 in a preset position on the mop handle 1.

[0090] In this embodiment, the driving component 70, the limiting component 71, and the rotating shaft 72 are integrally formed. This can be understood as the driving component 70 and the limiting component 71 being formed at different positions on the same component. Of course, the driving component 70 and the limiting component 71 can also be set as different components and then connected by corresponding structures to form a linkage.

[0091] Preferably, the outer shape and size of the left cover 74 and the right cover 75 are adapted to the mop handle 1. The outer sides of the left cover 74 and the right cover 75 can be supported by the inner surface of the mop handle 1 to prevent the left cover 74 and the right cover 75 from shaking inside the mop handle 1. The left cover 74 and the right cover 75 are fixedly installed by a snap-fit ​​structure to fix the drive component 70, the limiting component 71, the rotating shaft 72, the elastic component 73 and the nut 78 between the left cover 74 and the right cover 75 so that they do not fall off, thus forming a whole. There is no need to insert each component into the mop handle 1 for installation separately, or for them to fall off during the process of installing them into the mop handle 1 after the positioning mechanism is assembled. Example 2

[0092] The difference between this embodiment and embodiment 1 is that the liquid spraying mechanism 7 uses a liquid pump to dispense liquid.

[0093] In this embodiment, as Figure 7 The spray mechanism 7 includes a pressing part 12, a housing 18, a spray nozzle 14, and a liquid pump 27. The housing 18 has a cavity and a space for installing the pressing part 12. The cavity forms a liquid storage chamber 13. The liquid pump 27 is installed between the pressing part 12 and the liquid storage chamber 13, or installed in the liquid storage chamber 13. The bottom of the housing 18 or the side near the wiping object 3 is provided with a spray nozzle 14. When in use, the pressing part 12 drives the liquid pump 27 to spray the cleaning liquid in the liquid storage chamber 13 out from the spray nozzle 14.

[0094] Preferred, such as, 7 and Figure 13 The first type of liquid pump 27 has the following structure: The liquid pump 27 includes a pump housing 28, a pump core 29, an inlet pipe 30, an inlet valve 31, an outlet pipe 32, and an outlet valve 33. The pump housing 28 has a cavity, within which the pump core 29 is movably installed. A sealing ring 34 and a spring 35 are provided between the pump core 29 and the pump housing 28. The outer end of the pump core 29 extends from the pump housing 28 to form a pressing part 12 or cooperates with the pressing part 12. The cavity also has... It has an inlet 36 and an outlet 37. The inlet 36 is connected to the inlet pipe 30 through the inlet valve 31, and the outlet 37 is connected to the outlet pipe 32 through the outlet valve 33. The end of the inlet pipe 30 is located in the storage chamber 13, and the end of the outlet pipe 32 is connected to the spray nozzle 14. The storage chamber 13 is also provided with a filling port 38 for replenishing cleaning fluid into the storage chamber 13. The filling port 38 is provided with a removable sealing plug 39.

[0095] The operation of this liquid pump 27 is as follows: the pump core 29 moves into the pump housing 28, squeezing the air inside the pump core 29, closing the inlet valve 31 and opening the outlet valve 33, allowing the air inside the pump housing 28 to leave through the outlet pipe 32; the spring 35 drives the pump core 29 to move outward to reset, increasing the volume between the pump core 29 and the pump housing 28, decreasing the pressure, causing the outlet valve 33 to close and the inlet valve 31 to open. The pressure difference between the outlet valve 33 and the storage chamber 13 causes the cleaning liquid in the outlet chamber to enter the outlet valve 33 through the inlet pipe 30 and the inlet valve 31, completing the pumping process at the inlet valve 31; the pump core 29 moves into the pump housing 28 again, changing the hydraulic pressure inside the liquid pump 27, and the pressure difference between the liquid pump 27 and the outside causes the inlet valve 31 to close and the outlet valve 33 to open, allowing the cleaning liquid inside the pump housing 28 to be sprayed out through the outlet pipe 32 and the spray nozzle 14.

[0096] In this embodiment, the housing 18 includes a front housing 40 and a rear housing 41, which together form a liquid storage cavity 13. A partition 42 is integrally formed on the rear housing 41, which divides the rear housing 41 into upper and lower parts. The lower part of the rear housing 41 forms the liquid storage cavity 13, and the upper part of the rear housing 41 forms an area for installing the pressing part 12. The middle part of the partition 42 extends into the liquid storage cavity 13 to form a pump housing 28 integrally formed with the rear housing 41. The inlet 36, outlet 37 and the hole for installing the pump core 29 on the pump housing 28 connect the upper and lower parts of the rear housing 41.

[0097] In this embodiment, both the inlet valve 31 and the outlet valve 33 are duckbill valves, and the mouths of the two duckbill valves face opposite directions.

[0098] Preferred, such as Figure 14 A reinforcing ring 44 is provided slightly inward from the outer periphery of the front shell 40. When the front shell 40 and the rear shell 41 are installed, the reinforcing ring 44 is inserted into the rear shell 41 and fits the surface of the rear shell 41. After installation, the front and rear shells 41 have two sets of approximately perpendicular mating surfaces 45. The two sets of mating surfaces 45 work together to prevent the cleaning fluid in the liquid storage chamber 13 from leaking out. To further prevent leakage, adhesive, sealing accessories, or welding can be used between the mating surfaces 45.

[0099] In other embodiments, the structures of the front shell 40 and the rear shell 41 can be interchanged. For example, the partition 42 and the pump shell 28 are integrally formed on the front shell 40, and the rear shell 41 is provided with a reinforcing ring 44, which is inserted into the front shell 40 and adapted to the surface of the front shell 40.

[0100] Preferably, the second type of liquid pump 27 has the following structure: the liquid pump 27 includes a pump housing 28, a pump core 29, a seal 46, a moving part 47, an inlet valve 31, and a spring 35. The pump housing 28 has two open ends for inlet and outlet liquid respectively. The inlet 36 has a constricted section 48 with a smaller diameter than other parts of the pump housing 28. The inlet valve 31 is installed downstream of the constricted section 48. The seal 46 is fixedly installed at one end of the outlet 37, and a first connecting element is located at the center of the seal 46. The first connecting hole 49 has a first interlayer 50 and a second interlayer 51 on its outer side. The pump core 29 and the movable part 47 are respectively installed at the upstream and downstream positions of the first connecting hole 49. The movable part 47 has a through second connecting hole 52, and the pump core 29 has a through third connecting hole 53. The downstream of the pump core 29 is inserted into the second connecting hole 52 for installation, so that the second connecting hole 52 and the third connecting hole 53 are connected. The downstream of the second connecting hole 52 is connected to the spray nozzle 14 through the liquid outlet pipe 32.

[0101] The operating principle of this liquid pump 27 is as follows:

[0102] In the spraying state, pressing the movable part 47 drives the pump core 29 to move upstream. The third connecting hole 53 is disengaged from the seal 46 to connect the second connecting hole 52 and the cavity inside the pump housing 28. The movable part 47 and the pump core 29 continue to move upstream until they drive the seal 46 to move synchronously to compress the volume of the cavity in the pump housing 28. During the process of the cavity volume of the pump housing 28 shrinking, the inlet pump blocks the inlet port 36. The cleaning liquid in the pump housing 28 cannot flow back to the storage chamber 13 and can only flow out through the second connecting hole 52, the third connecting hole 53, the outlet pipe 32 and the spray port 14.

[0103] In the liquid inlet state, the release of the spring force of spring 35 causes pump core 29 and moving part 47 to move downstream synchronously, so that the third connecting hole 53 is blocked by the seal 46, and the second connecting hole 52 and the cavity inside pump housing 28 are blocked. Pump core 29 and moving part 47 continue to move downstream until they drive the seal 46 to move synchronously, increasing the volume of the cavity of pump housing 28. During the process of increasing the volume of the cavity of pump housing 28, the hydraulic or air pressure on the upstream and downstream sides of the liquid inlet valve 31 is different. The cleaning fluid in the liquid storage chamber 13 pushes the liquid inlet pump to move downstream and opens the liquid inlet 36. The cleaning fluid is replenished into the cavity of pump housing 28. After pump core 29, seal 46 and moving part 47 move to the initial position, the liquid inlet of pump housing 28 is completed.

[0104] Preferably, the sealing member 46 is provided with a thin wall 54 on the outside of the first interlayer 50 and the second interlayer 51. The thin wall 54 is flared. During the movement of the sealing member 46 in different directions, the hydraulic or air pressure in the cavity of the pump housing 28 causes the thin wall 54 at different positions to deform and fit against the inner wall of the pump housing 28, so as to avoid air or liquid leakage from the pump housing 28.

[0105] In this embodiment, upstream and downstream refer to the relative positions of the liquid in the storage chamber 13 flowing to the spray nozzle 14 via the liquid pump 27. This is independent of the installation direction of the spray mechanism 7 and the liquid pump 27. That is, regardless of the orientation of the spray mechanism 7 and the liquid pump 27, the direction of the cleaning liquid flowing out of the storage chamber 13 is fixed. In this embodiment, the flow direction of the cleaning liquid is sequentially: storage chamber 13, inlet pipe 30, pump housing 28, outlet pipe 32 and spray nozzle 14.

[0106] Preferably, the third type of liquid pump 27 is configured as an electric pump, which is installed inside or outside the liquid storage chamber 13. The electric pump is connected to the spray nozzle 14 and drives the cleaning liquid in the liquid storage chamber 13 to the spray nozzle 14 for spraying. Example 3

[0107] The difference between this embodiment and embodiment 2 is that the liquid spraying mechanism 7 does not have a separate liquid pump 27.

[0108] The first liquid discharge method in this embodiment is as follows: Figure 18 The spraying mechanism 7 includes a pressing part 12, a housing 18, and a spray nozzle 14. The cavity inside the housing 18 forms a liquid storage chamber 13. The spray nozzle 14 is located at the bottom of the housing 18. The top of the housing 18 is open. The pressing part 12 is configured as a push rod, with its lower end inserted into the liquid storage chamber 13. The pressing part 12 moves downward in the liquid storage chamber 13 to squeeze the cleaning liquid out of the liquid storage chamber 13.

[0109] The second liquid dispensing method in this embodiment is that the liquid spraying mechanism 7 includes a pressing part 12, a housing 18, a liquid spraying port 14, and a liquid spraying valve 55. Specifically, the cavity inside the housing 18 forms a liquid storage chamber 13, and the spray nozzle 14 is located at the lower position of the liquid storage chamber 13. A sealing plug 39 is detachably connected to the liquid filling port 38 of the housing 18. After the spray mechanism 7 is installed, the housing 41 body 18 forms a seal, that is, the spray valve 55 can prevent the cleaning liquid from flowing out when the housing 18 is rotated to any angle. The pressing part 12 is made of flexible material. By pressing the pressing part 12, it deforms into the liquid storage chamber 13, reducing the volume of the liquid storage chamber 13 and creating an air pressure difference between the liquid storage chamber 13 and the outside. The spray valve 55 opens due to the air pressure difference and sprays liquid outward. When the pressing part 12 is released, the pressing part 12 deforms back to its original position. After the liquid is sprayed, the internal air pressure of the liquid storage chamber 13 is less than the external air pressure. The internal and external air pressure difference causes the spray valve 55 to open and replenish air into the liquid storage chamber 13 until the internal and external air pressure of the liquid storage chamber 13 are balanced.

[0110] Preferred, such as Figure 19 The spray mechanism 7 can be configured such that the housing 18 is made of rigid plastic and the pressing part 12 is made of flexible material, and the housing 18 and the pressing part 12 are connected by a sealing method; for example Figure 20The spraying mechanism 7 can also have its housing 18 made entirely of a flexible material, with a pressing part 12 formed on the surface of the housing 18 where it can be pressed to deform, thereby achieving pressure-driven spraying of liquid; for example Figure 21 The spraying mechanism 7 can also be an integral structure of the housing 18 that is retractable and foldable. The surface of the housing 18 can be pressed to form a pressing part 12, thereby realizing the spraying of liquid by changing the air pressure.

[0111] Furthermore, such as Figure 22 The housing 18 is made of rigid plastic, and the pressing part 12 is made of flexible material or is configured as a retractable and foldable structure. The pressing part 12 is connected to the housing 18 through an air pipe 56. When the pressing part 12 is squeezed from the outside of the housing 18, the air in the pressing part 12 enters the liquid storage chamber 13 through the air pipe 56 and squeezes the cleaning liquid out of the spray nozzle 14. Example 4

[0112] The difference between this embodiment and embodiment 3 lies in the structure of the mounting platform 19.

[0113] In this embodiment, the mounting platform 19 refers to the device used to fix and connect the flat mop and the spray mechanism 7 as a whole. The mounting platform 19 can be set on the flat mop, or on the spray mechanism 7, or on both the flat mop and the spray mechanism 7. After the flat mop and the spray mechanism 7 are installed, the fixing device is combined to form the mounting platform 19.

[0114] In this embodiment, the flat mop and the spraying mechanism 7 are two independent entities during production and processing. The components of the spraying mechanism 7 are molded and installed into a complete spraying module before being installed with the flat mop. This improves the efficiency of the production, installation, and inspection of the spraying mechanism 7, and reduces the replacement and scrap costs of the spraying mechanism 7 and the flat mop if they fail the water test.

[0115] The mounting platform 19 in this embodiment can be implemented in various structures. In some structures, the mounting platform 19 eliminates the need for the spraying mechanism 7 to be used with a specially designed flat mop. The mounting platform 19 makes the spraying mechanism 7 compatible with flat mops that are sold on the market and have been purchased by users, thus broadening the applicability of the spraying mechanism 7.

[0116] Preferably, the first installation platform 19 is configured as follows: Figure 23-24The upper part of the squeezing sleeve 5 is provided with an outwardly protruding raised frame 57. The outer end of the frame 57 is flush with the inner side wall of the frame 57. The first protrusion 58 is provided in an L shape. The two arms of the first protrusion 58 extending in two directions form a slot 59. The housing 18 of the spraying mechanism 7 is provided with an extension platform 60. The side of the extension platform 60 is provided with a second protrusion 61. During installation, the first protrusion 58 and the second protrusion 61 are misaligned. The extension platform 60 is aligned with the frame 57 and inserted. The spraying mechanism 7 is rotated in a preset direction so that the second protrusion 61 enters the slot 59 formed by the first protrusion 58, thereby realizing the quick installation and disassembly of the spraying mechanism 7. In this way, the frame 57 and the extension platform 60 together form the installation platform 19.

[0117] More specifically, the frame 57 is square, and each of the two opposite inner sidewalls of the frame 57 is provided with a first protrusion 58. The two first protrusions 58 are symmetrical. The extension platform 60 is circular and its diameter is smaller than the length of the shortest side of the frame 57. During installation, the second protrusion 61 is aligned with the corner of the frame 57 and the extension platform 60 is inserted into the frame 57 until the extension platform 60 abuts against the frame 57. At this time, the spraying mechanism 7 can be rotated to insert the second protrusion 61 into the slot 59 for positioning. The square shape of the frame 57 allows the corner area of ​​the frame 57 to make room for the insertion of the second protrusion 61 to form an installation positioning point. That is, other positions except the corners will abut against the second protrusion 61 to prevent the second protrusion 61 from being inserted into the frame 57, thereby simplifying the positioning of the spraying mechanism 7 during installation. In addition, to prevent the second protrusion 61 from being inserted into the corner away from the slot 59, in this embodiment, a foolproof position 62 is provided at the corner away from the slot 59. The foolproof position 62 is achieved by setting a different shape from the other corner, setting an indicator, or setting a stop.

[0118] Of course, in other embodiments, such as Figure 25 Alternatively, an L-shaped slot 59 can be provided on one of the frame 57 and the extension platform 60, and a second protrusion 61 can be provided on the other. The installation and positioning can be achieved by aligning the second protrusion 61 with the outer end of the slot 59.

[0119] Preferably, the second installation platform 19 is configured as follows: Figure 26 The upper part of the squeezing sleeve 5 is provided with a frame 57, the inner side wall of the frame 57 is provided with an internal thread 63, the housing 18 is provided with an extension platform 60, the side of the extension platform 60 is provided with an external thread 64, the frame 57 and the extension platform 60 together form an installation platform 19, and during installation, the spraying mechanism 7 is rotated to make it threadedly connected with the extension platform 60.

[0120] Preferably, the third installation platform 19 is configured as follows: Figure 27The upper part of the squeezing sleeve 5 is provided with a frame 57, and the inner side wall of the frame 57 is provided with a male buckle 65. The housing 18 is provided with an extension platform 60, and the side of the extension platform 60 is provided with a female buckle 66. The frame 57 and the extension platform 60 together form an installation platform 19. During installation, the spraying mechanism 7 is pressed to make it snap-fit ​​with the extension platform 60.

[0121] Preferably, the fourth type of installation platform 19 is configured such that an extension platform 60 is provided on one or both of the squeezing sleeve 5 and the housing 18, and the squeezing sleeve 5 and the spraying mechanism 7 are fixedly connected by screws installed on the extension platform 60.

[0122] In the above embodiments, all four mounting platforms 19 are configured as detachable structures, allowing the spraying mechanism 7 to be fixedly installed and used in conjunction with the flat mop to spray liquid onto the wiping material 3. Alternatively, the flat mop and the spraying mechanism 7 can be used independently after the spraying mechanism 7 is disassembled. Simultaneously, the raised or extended portions on the mounting platform 19 allow the spraying mechanism 7 to suspend outside the wringer sleeve 5, enabling the upper ends of the mop head 2 and the wiping material 3 to be inserted into the gap between the spraying mechanism 7 and the wringer sleeve 5 for positioning or spraying.

[0123] In other embodiments, the water squeezing sleeve 5 and the spraying mechanism 7 can be connected in a non-detachable structure by means of riveting, welding, or other methods, based on the use of the frame 57 and the extension platform 60.

[0124] All of the above-mentioned installation platforms 19 require specially made wringer sleeves 5 to install the spraying mechanism 7. In order to facilitate the use of the spraying mechanism 7 with ordinary wringer sleeves 5 and ordinary mops, in this embodiment, the installation platform 19 can also be set on the spraying mechanism 7 as a whole.

[0125] Specifically, such as Figure 28 The housing 18 of the spray mechanism 7 is provided with an extension platform 60. The extension platform 60 is equipped with clamps, rings 67, straps, tube clamps, cable ties, Velcro straps, and other clamping structures. These clamping structures fix the spray mechanism 7 to a regular mop or wringer 5 by wrapping around the mop handle 1 or wringer 5. The elasticity and tightness of the clamping structures can be adjusted to fix the spray mechanism 7 to mops or wringer 5 of different sizes. The extension platform 60 and the clamping structures together form an installation platform 19. The clamping structures are used to install the spray mechanism 7 on the mop, and the extension platform 60 is used to control the distance between the spray mechanism 7 and the mop handle 1 and wringer 5 to avoid protruding parts on the mop affecting the installation of the spray mechanism 7. It also facilitates the mop head 2 and the wiping material 3 to enter the gap between the spray mechanism 7 and the mop handle 1 or wringer 5 for positioning and spraying. Even if the installed mop is not equipped with a wringer 4, the installed spray mechanism 7 can spray liquid onto the wiping material 3, and then place the wiping material 3 on the mop bucket or other cleaning devices for cleaning, thereby expanding the range of mops that can be used with the spray mechanism 7.

[0126] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
