Description

[0001] This application is a divisional application. The application date of the original application is November 14, 2017, the application number is 201711119340.6, and the name of the invention is "Squeezed flat mop cleaning tool. Technical Field

[0002] The invention relates to a squeeze flat mop cleaning tool. Background Art

[0003] In the prior art, there are three ways to dehydrate a flat mop: foot-operated squeezing dehydration, in which a foot-operated squeezing device is arranged on the mop bucket, and the foot-operated squeezing device includes a squeezing basket arranged in the mop bucket, a pedal hinged on the upper part of the mop bucket and opposite to the squeezing basket, and the pedal and the squeezing basket form a squeezing space. When dehydrating, the mop on the mop board of the flat mop needs to be removed first, and the mop needs to be placed in the squeezing space, and then the pedal is stepped on to shrink the squeezing space to achieve the purpose of squeezing out the water on the mop. This form of dehydration method requires the design of a complex foot-operated squeezing device, which is costly; when squeezing water, the mop needs to be removed first, and the foot needs to be lifted for stepping operation, which is troublesome to operate.

[0004] The second method is centrifugal spin dehydration, which uses a hand-pressed spin mop rod. When dehydrating, the mop plate of the flat mop needs to be bent at both ends and placed in the dehydration area of ​​the mop bucket, and the mop rod is pressed down to make the mop plate of the flat mop spin centrifugally dehydrated. This form of dehydration method requires the mop plate of the flat mop to be designed as a bendable structure, which is relatively complex in structure and needs to be coordinated with the hand-pressed spin mop rod, which is costly.

[0005] The third method is hand-push squeeze dehydration, such as Chinese invention patents ZL200720192814.5, ZL201320019718.6, ZL201420624020.1, etc., which include a mop rod, a flat mop plate movably connected to the mop rod, and a water squeezing mechanism on the mop rod, and the water squeezing mechanism and the flat mop plate are relatively squeezed and moved to achieve squeezing and cleaning of the wiped objects on the flat mop plate. It also has the disadvantage that: when squeezing water, one hand needs to hold the mop rod for positioning and the other hand needs to hold the water squeezing mechanism, and the relative squeezing movement between the water squeezing mechanism and the flat mop plate is achieved by pushing and pulling the water squeezing mechanism with one hand, which is very laborious and not easy to operate.

[0006] In order to overcome the shortcomings of the above-mentioned flat mop, the Chinese invention patent with patent number ZL201620870001.6 provides a squeezing flat mop cleaning tool, which has a cleaning area and a squeezing area in different positions. The flat mop is squeezed and cleaned in the cleaning area and squeezed and squeezed water in the squeezing area through a squeezing device. It also has the disadvantage that it needs to switch between the cleaning area and the squeezing area when cleaning and squeezing water, and there is still a deficiency of inconvenience in operation. At the same time, when squeezing and squeezing water of the flat mop, it is easy to lift the mop bucket after lifting the flat mop upwards, and it is impossible to obtain a stable and appropriate squeezing force when pressing the flat mop downwards.

Therefore, when the wiping material on the flat mop head is cleaned and squeezed out, the cleaning operation and the squeezing operation can be completed in the same area, i.e., the squeezing area: when cleaning, there is water in the squeezing area, and then the flat mop moves back and forth to squeeze out the water on the wiping material and flow it to the water holding area. After the wiping material squeezes out the water, it absorbs the water. By repeating the above process, most of the water in the squeezing area can be transferred to the water holding area. In this process, the cleaning operation and the squeezing operation are also completed at the same time, and the operation is very simple.

[0094] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0095] Reference Figure 1-Figure 54 The squeezing flat mop cleaning tool comprises a mop bucket and a flat mop 1, wherein the flat mop 1 comprises a mop rod 2 and a hard flat mop head 3 movably connected to the mop rod 2, wherein the flat mop head 3 is provided with a wiping material 4, and the wiping material 4 is usually arranged on the back of the flat mop head 3. The movably connected mode of the flat mop head 3 and the mop rod 2 is prior art and will not be described in detail here.

[0096] The mop bucket is provided with a squeezing frame 5, and the squeezing frame 5 is provided with an opening. A squeezer is provided on the squeezing frame on one side of the opening, and a squeezer part extends into the opening, and a squeezing opening 6 is formed between the squeezer and the other side of the opening. When squeezing and cleaning the wiping material, the flat mop head 3 rotates to a squeezing and cleaning state, and the flat mop is inserted into the squeezing opening 6 and reciprocates, so that the wiping material 4 is squeezed and squeezed and cleaned by the squeezer. The rotation of the flat mop head 3 to the squeezing and cleaning state is usually reflected in the flat mop head 3 rotating to a state parallel or substantially parallel to the mop rod 2.

[0097] The mop bucket in the present invention includes a squeezing area 7 and a water storage area 8 located at different positions. The squeezing frame 5 is located above the squeezing area so that the squeezing frame 5 corresponds to the squeezing area. Usually, the squeezing frame 5 is installed on the mop bucket in the squeezing area. The squeezing frame or the squeezer has a water channel for leading out the water squeezed out of the wiping material. The water channel is generally directly formed on the squeezing frame 5 or the squeezer. The formation and arrangement of the squeezing area 7 and the water storage area 8 are not limited. Figure 2 , 3 , 23, 24, 25, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, the squeezing area 7 and the water holding area 8 are arranged side by side, one on the left and one on the right, and the squeezing area 7 and the water holding area 8 can be a barrel separated by a partition, or can be two barrels; Fig.34 , 35 In , 36 and 37, the squeezing area 7 and the water holding area 8 are arranged inside and outside, that is, the mop bucket includes an inner bucket 9 and an outer bucket 10, the inner bucket 9 is located in the outer bucket 10, the area inside the inner bucket 9 forms the squeezing area, and the area inside the outer bucket 10 forms the water holding area.

[0098] The squeezer is movably connected to the squeezing frame 5. When the flat mop head 3 is pressed down, the wiping material 4 drives the squeezer to move to a narrow position, thereby making the squeezing opening 6 smaller. At this time, the wiping material 4 obtains a relatively stable and appropriate squeezing force; when the flat mop head 3 is pulled up, the wiping material 4 drives the squeezer to move in a direction away from the narrow position, thereby making the squeezing opening 6 larger. At this time, the squeezing force applied by the squeezer to the wiping material 4 is smaller, so the mop bucket will not be pulled up during the process of pulling the flat mop up.

[0099] exist Figure 2-Figure 33 In the embodiment, the squeezer adopts a stroke plate 11, and the stroke plate 11 is swingably arranged on the squeeze frame 5. When the flat mop head 3 is pressed down, the wiping material drives the stroke plate 11 to rotate downward to a narrow position, thereby making the squeeze opening 6 smaller; when the flat mop head 3 is pulled up, the wiping material drives the stroke plate 11 to rotate upward, thereby making the squeeze opening 6 larger.

[0100] The swingable installation method of the stroke plate 11 can adopt various structural forms. The following lists several specific installation methods of the stroke plate: 1. As Figure 8 , Fig. 9 As shown, both ends of the stroke plate 11 are provided with rotating pins 12, and the two rotating pins 12 are respectively inserted into the extrusion frame 5, so that the stroke plate 11 can swing with the rotating pins as the axis.

[0101] 2. If Fig.10 , Fig.11 As shown, the extrusion frame 5 is provided with a convex shaft 13, and the convex shaft 13 is respectively Inserted into the two ends of the stroke plate 11, the stroke plate 11 can swing around the convex shaft 13 as the axis.

[0102] 3. Such as Fig.12 , 13 As shown, a pivot seat 14 is provided on the extrusion frame 5, and the side of the pull plate 11 is pivotally connected to the pivot seat 14, so that the pull plate 11 can swing with the pivot point of the side as the axis.

[0103] 4. Such as Fig.14 , 15 As shown, the extrusion frame 5 is provided with a base 15, the base 15 is provided with a bayonet 16, and the stroke plate 11 is provided with a clamping shaft 17. The clamping shaft 17 is inserted into the bayonet 16 of the base and then rotated, and the stroke plate 11 can swing around the clamping shaft 17 as the axis.

[0104] The specific location of the narrow position can be achieved in the following manner: a limiting device for limiting the position of the narrow position is provided on the extrusion frame 5, and the limiting device is used to specify the specific location of the narrow position. The limiting device can also simultaneously limit the maximum extrusion opening position when the extrusion opening becomes larger. Figure 8 , 9 , 10, 11, 12, 13, 14, and 15, the limiting device is a row of limiting seats 18 arranged on the extrusion frame 5, the limiting seats are located on one side of the open extruder, the limiting seats 18 can be directly arranged on the extrusion frame 5, and can also be arranged on the pivot seat 14, the limiting seat 18 is provided with a limiting recess 19, the said stroke plate 11 is located in the limiting recess 19, the said stroke plate 11 reaches the narrow position when it touches one side of the limiting seat 18, and reaches the maximum extrusion port position when it touches the other side of the limiting seat 18. A lug 20 can also be arranged on the stroke plate 11 to assist in limiting, and the maximum extrusion port position is reached by the contact of the lug with the limiting seat.

[0105] Of course, the limiting device can also adopt other structural forms, such as Fig.17 As shown, outwardly protruding limit blocks 21 are provided at both ends of the stroking plate 11, and a limit opening 22 is provided on the extrusion frame 5. The limit blocks 21 are inserted into the limit opening 22, and the limit blocks 21 move in the limit opening 22. When the limit blocks 21 touch one side of the limit opening 22, the limit blocks 21 reach a narrow position, and when they touch the other side of the limit opening 22, the limit blocks reach a maximum extrusion position. For example, as shown in the figure, the limit device is a limit groove 23 provided on the extrusion frame 5, and the two ends of the stroking plate 11 are respectively inserted into the limit groove 23. When the stroking plate 11 touches one side of the limit groove 23, the limit blocks reach a narrow position, and when they touch the other side of the limit groove 23, the limit blocks reach a maximum extrusion position.

[0106] The limiting device can also be provided on the extrusion frame with two blocking parts that block the stroke plate 11. The blocking parts form the limiting device. When the stroke plate touches one blocking part, it reaches the narrow position, and when it touches the other blocking part, it reaches the maximum extrusion port position.

[0107] Reference Fig. 20 , Fig.21 Another movable connection mode with a self-limiting device can be adopted between the stroking plate 11 and the extrusion frame 5: the extrusion frame 5 is provided with oblique grooves 24 corresponding to the two ends of the stroking plate 11, the two ends of the stroking plate 11 are inserted into the oblique grooves 24, and there is a movable space between the stroking plate 11 and the oblique grooves 24 along the thickness direction of the stroking plate. When the flat mop head 3 is moved back and forth, the wiping object 4 contacts the stroking plate 11, driving the stroking plate 11 to flip in the oblique grooves 24, so that the stroking plate 11 has a certain rotation angle, so as to achieve the effect of adjusting the opening size of the extrusion port. And due to the limitation of the oblique grooves 24, the stroking plate 11 can only move within a certain range, so that it can reach the narrow position and the maximum extrusion port position.

[0108] Alternatively, the two ends of the stroke plate are provided with oblique grooves, and the extrusion frame is provided with plug plates corresponding to the two oblique grooves, the plug plates are inserted into the oblique grooves, and there is a movable space between the plug plates and the oblique grooves along the thickness direction of the stroke plate. When the water squeezing handle is pushed or pulled, the wiping object contacts the stroke plate, which drives the stroke plate to flip, so that the stroke plate has a certain rotation angle, so as to achieve the effect of adjusting the opening size of the extrusion port. And due to the matching restrictions of the oblique grooves and the plug plates, the stroke plate can only move within a certain range, so that it can reach the narrow position and the maximum extrusion port position.

[0109] In the foregoing specific embodiments, the stroking plate reaches the narrow position by the wiping material 4 driving the stroking plate 11 to swing (rotate). The stroking plate 11 can also reach the narrow position in other ways, such as providing an elastic device in the extrusion frame 5, the elastic device acting on the stroking plate 11 to place it in a narrow position so that the extrusion opening is smaller. In this case, the stroking plate 11 is initially located in the narrow position, and there is no need for the wiping material 4 on the flat mop head to be pressed down to drive it to rotate to the narrow position. When the flat mop head 3 is pulled upward, the frictional extrusion force between the wiping material 4 and the stroking plate 11 overcomes the elastic force of the elastic device, thereby causing the stroking plate 11 to rotate upward, thereby enlarging the extrusion opening. Figure 6 As shown, the elastic device can be a compression spring 25, one end of the compression spring 25 presses on the extrusion frame 5, and the other end of the compression spring 25 presses on the stroke plate 11, so that the stroke plate 11 is located in the narrow position. Figure 7 As shown, the elastic device can be a torsion spring 26, one end of the torsion spring 26 presses on the extrusion frame 5, and the other end of the torsion spring 26 presses on the pull plate 11, so that the pull plate 11 is located in the narrow position.

[0110] In the above description, the extruder is described as a swingable stroke plate. Of course, the extruder can also be connected to the extrusion frame in other ways to achieve the purpose of changing the size of the extrusion port. Fig.35 , 36As shown in Figures 38, the extrusion frame 5 is slidably connected with the extruder 27. When the flat mop head 3 is pressed down, the wipe 4 drives the extruder 27 to slide obliquely downward to a narrow position, thereby making the extrusion opening smaller; when the flat mop head 3 is pulled up, the wipe 4 drives the extruder 27 to rotate obliquely upward, thereby making the extrusion opening larger. In this case, there is no need to make special restrictions on the shape of the extruder 27. The extruder 27 can be in the shape of a strip, a plate, or an extrusion roller. The specific sliding connection between the extrusion frame 5 and the extruder 27 can be: the extrusion frame 5 is provided with an oblique slide 28, and sliders 29 are provided at both ends of the extruder 27, and the sliders 29 are located in the oblique slide 28. The oblique slide 28 also exists as a limiting device: when the slider 29 slides to the lower end of the oblique slide 28, the extruder 27 is located in a narrow position, and when the slider 29 slides to at least the upper end of the oblique slide 28, the extrusion opening reaches the maximum opening position.

[0111] Alternatively, a slider is provided on the extrusion frame, and inclined slide grooves are provided at both ends of the extruder, and the slider is located in the inclined slide grooves.

[0112] In this embodiment, a water diversion mechanism is provided on the outside of the water channel. When the flat mop cleans and squeezes the wipes in the squeezing area 7, the water squeezed out of the wipes can be blocked by the water diversion mechanism and then flow back to the squeezing area 7, so that the returned water forms a top-down shower on the wipes 4; the water squeezed out of the wipes 4 can also be guided to the water storage area 8 by the water diversion mechanism. The significance of setting the water diversion mechanism is that the flat mop cleaning tool of the present invention cleans and squeezes the wipes in the squeezing area 7. In fact, the flat mop realizes the process of cleaning and squeezing at the same time during the reciprocating motion in the squeezing area 7. The water in the squeezing area is sucked into the wipes 4, and the water squeezed out of the wipes 4 is guided to the water storage area 8 through the water channel. The wipes 4 continuously absorb and squeeze water, and finally most of the water in the squeezing area 7 is transferred to the water storage area 8, and the wipes 4 have been squeezed dry at this time. However, since the squeezing process of this washing and squeezing method mainly relies on the water absorption of the wipe 4, the volume of the squeezing area is usually not too large and the squeezing area 7 is likely to be filled with water, otherwise the squeezing process of the wipe will be too long. The resulting problem is that during washing, the upper part of the wipe 4 is basically not stained with water, so the cleaning effect of the upper part of the wipe is poor.

[0113] After the water diversion mechanism is provided, the water squeezed out of the wipe 4 can be blocked by the water diversion mechanism and then flow back to the squeezing area 7, so that the returned water forms a shower on the wipe 4 from top to bottom, so that the wipe 4 is fully wetted, thereby achieving a better cleaning effect. In addition, the water squeezed out of the wipe 4 can also be guided to the water storage area 8 by the water diversion mechanism to achieve water transfer, and finally the purpose of squeezing the wipe dry can be achieved.

[0114] The water diversion mechanism can be in two forms: movable and fixed. Fig. 22 , 23 As shown in , 24, 25, 26, and 27, the specific structure of the movable water diversion mechanism can be: the water diversion mechanism can be in a water-blocking state or a drainage state, and the water diversion mechanism can achieve the conversion between the water-blocking state and the drainage state through a control mechanism; when the wipe is cleaned, the water diversion conversion mechanism is in the water-blocking state, and the water squeezed out of the wipe is blocked by the water diversion conversion mechanism and then flows back to the squeezing area 7, so that the returned water forms a top-down shower on the wipe 4; when the wipe is squeezed, the water diversion conversion mechanism is in the drainage state, and the water squeezed out of the wipe is guided by the water diversion conversion mechanism to the water holding area 8, until most of the water in the squeezing area 7 is transferred to the water holding area.

[0115] The water diversion mechanism can specifically adopt a water diversion plate 30, which is rotatably installed on the outside of the water channel 31. After being rotated, the water diversion plate 30 can be in a water blocking state or a drainage state. The water diversion plate 30 can be an arc-shaped plate, a flat plate, a right-angle plate, etc. In the figure, the water diversion plate 30 is an arc-shaped plate. When the water diversion plate 30 is in a water blocking state, the concave surface of the arc-shaped plate faces the water channel 31 and the squeezing area 7, and the water diverted from the water channel 31 is blocked by the water diversion plate 30 and flows back to the squeezing area 7; when the water diversion plate 30 is in a drainage state, the concave surface of the arc-shaped plate faces the water holding area 8 (or faces away from the squeezing area), and the water diverted from the water channel 31 is guided to the water holding area 8 by the arc-shaped plate. The curved plate can also be turned 180° to block water and divert flow with the convex surface. When the water diversion plate is in the water blocking state, the convex surface of the curved plate faces the water channel and the extrusion area, and the water diverted from the water channel is blocked and flows back to the extrusion area; when the water diversion plate is in the diversion state, the convex surface of the curved plate faces the water storage area (or faces away from the extrusion area), and the water diverted from the water channel is guided to the water storage area by the curved plate. Of course, flat plates, right-angle plates, and two obtuse-angled plates can all achieve the above functions, and you only need to rotate the water diversion plate to a suitable angle.

[0116] The control mechanism for controlling the water guide plate 30 to switch between the water retaining state and the flow guide state can be in various forms, for example, Figure 2 , Fig. 22As shown, the control mechanism includes an adjusting slot 32 provided on the extrusion frame 5, an adjusting rod 33 is provided in the adjusting slot 32, and the adjusting rod 33 is connected to the water diversion plate 30. The adjusting rod 33 is moved to slide in the adjusting slot 32, thereby controlling the water diversion plate 30 to rotate to a water retaining state or a drainage state. A positioning mechanism can be provided between the adjusting rod 33 and the adjusting slot 32, so that the adjusting rod 33 is located in a water retaining state or a drainage state. For example, a slot is provided on the adjusting rod and two gear blocks are provided in the adjusting slot, one gear block corresponds to the water retaining state, and the other gear block corresponds to the drainage state. In this way, when the slot on the adjusting rod is snap-fitted with one gear block, it is automatically located in the water retaining state, and when the slot on the adjusting rod is snap-fitted with the other gear block, it is automatically located in the drainage state.

[0117] Of course, the control can also adopt other structural forms, such as Figure 3 , 25 As shown in , 26 and 27, the control mechanism includes a push-pull rod 34 that is inserted into the extrusion frame, a control block 35 is provided on the push-pull rod 34, and a controlled block 36 is provided on the water guide plate 30. The control block 35 can touch the controlled block 36, and when the push-pull rod 34 is pushed or pulled, the rotation of the water guide plate 30 is controlled by the cooperation of the control block 35 and the controlled block 36. Of course, the control block and the controlled block can also be replaced by other mechanisms, such as a connecting rod mechanism.

[0118] like Fig. 22 , 23 , 24, 25, 26, and 27, the specific structure of the fixed water diversion mechanism can be: the water diversion mechanism is a fixed water retaining device, which retains the water squeezed out of the wipes and then flows back to the squeezing area 7; the water retaining device is provided with a water leakage mechanism that leaks part of the water squeezed out of the wipes to the water holding area, and the water squeezed out of the wipes is partially transferred to the water holding area 8 through the water leakage mechanism until most of the water in the squeezing area 7 is transferred to the water holding area 8. The water retaining device can be a water retaining plate 37, and the water leakage mechanism is a hollow portion 38 provided on the water retaining plate, and the hollow portion 38 corresponds to the water holding area 8.

[0119] When most of the water in the squeezing area 7 is transferred to the water holding area 8, water needs to be added to the squeezing area 7 for cleaning again. A control valve 39 can be set between the squeezing area 7 and the water holding area 8 to control whether the two are connected. When cleaning again is needed, just open the control valve 39. The specific structural form of the control valve 39 can be: the pressurizing area and the water holding area are connected through a connecting pipeline, and a valve core is provided in the connecting pipeline. The control valve is connected to the control rod 43. After the valve core is pulled out by the control rod 43, the squeezing area 7 and the water holding area 8 can be connected. The control rod 43 can be integrated with the aforementioned push-pull rod 34, that is, they share a rod. Of course, the control valve 39 can also adopt a three-way valve or other structures.

[0120] Alternatively, in order to meet the need for water inlet to the squeezing area during re-cleaning, the squeezing area 7 and the water holding area 8 are connected via a slow-release hole 40. When the wipe is squeezed, the amount of water squeezed out is greater than the amount of water entering the squeezing area from the water holding area through the slow-release hole 40. Then, when squeezing, the water in the squeezing area 7 can be smoothly transferred to the water holding area 8. At the same time, after the squeezing rod is completed, the water in the water holding area 8 can automatically be squeezed into the squeezing area 7 through the slow-release hole 40 until the water level in the squeezing area 7 is level with the water level in the water holding area 8.

[0121] A buffer device may also be provided at the bottom of the squeezing area and / or the water holding area to provide buffering when the flat mop moves downward, so as to prevent the hard flat mop head from directly colliding with the barrel body. The buffer device may be a flexible pad 41, or other buffering mechanism, such as a buffer block connected to the bottom surface of the mop barrel by a spring.

[0122] like Fig.29 , 30 As shown, a frame 42 can be provided at the bottom of the squeezing area to reduce the amount of water absorbed in the final stage of squeezing. Of course, the shape of the frame is not limited to Fig.29 The shape of the surrounding frame 42 can also be a rectangle, square, polygon, circle, ellipse, special shape, grid, etc. The significance of providing the surrounding frame 42 is that during the cleaning and squeezing process of the wipe, as the water in the squeezing area 7 is continuously transferred to the water holding area 8, the water level in the squeezing area 7 continuously decreases. When the water level in the squeezing area 7 decreases below the surrounding frame 42, the water in the squeezing area 7 is divided into two parts, one part is located outside the surrounding frame 42, and the other part is located inside the surrounding frame 42.

[0123] If the flat-plate mop head corresponds to the surrounding frame 42, the flat-plate mop head will not come into contact with the water outside the surrounding frame 42 during the reciprocating motion. At this time, it is only necessary to suck the water inside the surrounding frame 42 to squeeze out the wipes on the flat-plate mop head. The setting of the surrounding frame 42 greatly reduces the amount of water that needs to be sucked out, which is beneficial to squeezing out the wipes; if the flat-plate mop head does not correspond to the surrounding frame 42, the flat-plate mop head will not come into contact with the water inside the surrounding frame 42 during the reciprocating motion. At this time, it is only necessary to suck out the water outside the surrounding frame 42 to squeeze out the wipes on the flat-plate mop head. The setting of the surrounding frame 42 greatly reduces the amount of water that needs to be sucked out, which is beneficial to squeezing out the wipes.

[0124] The flat mop head and the mop rod can be positioned by a positioning device to keep the flat mop head in a cleaning and squeezing state; when mopping the floor, the flat mop head is freed from the control of the positioning device and rotates to the mopping state. The positioning device allows the flat mop head to maintain a stable state during cleaning and squeezing, which is conducive to the frequent up and down movement of the flat mop head, and the mop bucket will not be lifted during the up and down movement of the flat mop. There are many structural forms of the positioning device, and several forms of the positioning device are listed below: like Fig.39 , Fig.40 As shown, the positioning device includes an iron block 433 arranged on the mop rod 2 and a magnet 44 arranged on the flat mop head 3. When the flat mop head 3 rotates to a state where it can be cleaned and squeezed, the iron block 433 and the magnet 44 are attracted to each other, and when mopping the floor, the iron block 433 and the magnet 44 are separated.

[0125] Alternatively, the positioning device includes a magnet disposed on the mop rod and an iron block disposed on the flat mop head. When the flat mop head rotates to a state where it can be cleaned and squeezed, the iron block is attracted to the magnet, and when mopping the floor, the iron block is separated from the magnet.

[0126] like Fig.41 , Fig.42 As shown, the positioning device includes a magic female buckle 45 provided on the flat mop head 3 and a magic male buckle 46 provided on the mop rod 2. When cleaning and squeezing water, the flat mop head and the mop rod are bonded together by the magic male buckle 46 and the magic female buckle 45; when mopping the floor, the magic male buckle 46 is detached from the magic female buckle 45.

[0127] Alternatively, the positioning device includes a magic male buckle provided on the flat mop head and a magic female buckle provided on the mop rod, and the flat mop head and the mop rod are bonded together by the magic male buckle and the magic female buckle during cleaning and squeezing; the magic male buckle and the magic female buckle are detached during mopping; like Fig.43 , Fig.44 As shown, the positioning device includes an elastic buckle 47 arranged on the mop rod 2, and the flat mop head 3 is provided with a buckle hole 48 adapted to the elastic buckle 47. When the flat mop head 3 is rotated to a state where it can be cleaned and squeezed, the elastic buckle 47 is buckled into the buckle hole 48; when mopping the floor, the elastic buckle 47 is disengaged from the buckle hole 48.

[0128] like Fig.45 , 46As shown, the positioning device includes an elastic buckle 49 provided on the flat mop head 3. When the flat mop head 3 is rotated to a state where it can be cleaned and squeezed, the mop rod 2 is buckled into the elastic buckle 49. When mopping the floor, the mop rod 2 is disengaged from the elastic buckle 49.

[0129] like Figure 47-54 As shown, the positioning device includes an elastic top member arranged in the mop rod 2, and the elastic top member includes a spring 50 and a top block 51. When washing and squeezing water, the top block 51 is pressed against the movable connection between the flat mop head 3 and the mop rod 2 by the force of the spring 50, thereby positioning the flat mop head 3; when mopping the floor, the mop rod 2 or the flat mop head 3 is pulled to rotate the mop rod 2 or the flat mop head 3, so that the flat mop head 3 is in a mopping state. The connection between the flat mop head 3 and the mop rod 2 can adopt such a structure: the flat mop head is longitudinally hinged with a hinge seat 52 (the so-called longitudinal hinge means that the hinge axis is parallel to the length direction of the flat mop head), the lower end of the mop rod 2 is transversely hinged on the hinge seat 52 (the so-called transverse hinge means that the hinge axis is parallel to the width direction of the flat mop head), the spring 50 and the top block 51 are located at the lower end of the mop rod 2, so that the top block 51 is pressed against the hinge seat 52. When the flat mop head 3 rotates to the cleaning and squeezing state, the flat mop head 3 rotates to be substantially parallel to the mop rod 2, and the top block 51 presses on the hinge seat 52 to form a downward force, so that the flat mop head 3 maintains this state. In order to achieve a better positioning effect, when the flat mop head 3 rotates to be substantially parallel to the mop rod, the hinge seat that presses against the top block 51 is set as a plane to increase the positioning ability; or a groove 53 is set at the hinge seat that presses against the top block 51, and a convex rib 54 or a clamping wheel 55 is set on the top block 51, and a better positioning effect is achieved by the convex rib 54 or the clamping wheel 55 being clamped into the groove 53.

[0130] Alternatively, the positioning device includes an elastic top piece arranged at the movable connection between the flat-plate mop head and the mop rod. When cleaning and squeezing water, the elastic top piece presses against the mop rod to position the flat-plate mop head; when mopping the floor, the mop rod or the flat-plate mop head rotates to put the flat-plate mop head in a mopping state.
