Description

Technical Field

[0001] This invention relates to sanitary ware, and more particularly to a folding mop with multiple squeezing points. Background Technology

[0002] As we all know, mops are indispensable cleaning tools in people's work and daily life. There are many types, including traditional mops made of cotton strips and wooden handles, and those wrung out by hand. With most mopped surfaces being tiled, wooden, or polished surfaces, existing mops mainly have two types of mop heads: one type is a foot-operated mop with a head made of cotton or cotton yarn, one end of which is flared out, and the head is rotated and dried by a matching wringer; the second type is a flat, rotating mop head made of sponge or cotton yarn, which is squeezed dry by a wringer. Currently, the wringer on flat rotating mops has the following problems: the upper and lower squeezing blocks are fixed, resulting in a simple wringing structure that is difficult to disassemble and clean. This design not only results in poor wringing effect, but also, because the squeezing blocks are generally made of plastic, they are prone to wear and even deformation after long-term use. Furthermore, the dryness of the mop head is difficult to control during wringing. Summary of the Invention

[0003] In view of the problems existing in the wringing device of the flat rotary mop in the above-mentioned technology, the present invention provides a folding mop with multiple squeezing positions that has a more reasonable structure, better wringing effect and longer service life.

[0004] The technical solution adopted by this invention to solve the technical problem is: a multi-squeezing folding mop, comprising a mop handle that can move within a sleeve under external force and a mop head movably connected to one end of the mop handle via a connector. One end of the connector is connected to one end of the mop handle, and the other end of the connector is movably connected to the mop head via a connector head and a connecting shaft. The mop head includes a squeezing plate movably connected to the connecting shaft via a connecting protrusion and a cleaning head fixedly fitted within the squeezing plate. The squeezing plate and the cleaning head can rotate from a position perpendicular to the axis of the mop handle to a position parallel to the axis of the mop handle. A wringing device is provided on the sleeve, and the wringing device includes a lower frame connected to the sleeve and an upper frame movably inserted into the lower frame. The upper part of the upper frame is spaced apart with several... The upper frame has a fixed support frame inside its inner cavity, and the support frame supports several rows of rotating squeezing rollers arranged in parallel at both ends. A movable squeezing strip is also present. The outer surface of the rotating squeezing rollers is provided with several drainage grooves spaced in a ring. The movable squeezing strip includes an integral upper square section and a lower conical section, the width of which gradually decreases from top to bottom. A water guiding channel is provided through the upper square section and the lower conical section in the movable squeezing strip. Guide rods are provided at both ends of the movable squeezing strip, and these guide rods are movably mounted in movable guide arc grooves at both ends of the support frame. The height of the movable guide arc grooves gradually decreases from the position where the cleaning head extends to the position where it extends. Several squeezing wheels are provided on the axle inside the lower frame.

[0005] Furthermore, a linkage plate is provided in the lower frame, and wedge-shaped blocks are provided at both ends of the linkage plate. The top surfaces of the wedge-shaped blocks have the same inclination direction and angle. Guide grooves are provided opposite to each other on the linkage plate between the wedge-shaped blocks. A drive groove in the vertical direction is provided on the wedge-shaped blocks between the two opposite guide grooves. A rotatable handwheel is provided in the middle of the lower frame. A drive wheel is provided off-center from the center of the handwheel and can be moved into the drive groove on the linkage plate. When the drive wheel rotates in the drive groove with the handwheel, it can make the linkage plate move left and right. A support plate is provided on the wedge-shaped blocks. When the wedge-shaped blocks move with the linkage plate, it can make the support plate move up and down. Each support plate has a rotating extrusion wheel at its upper end that can be closely attached to the extrusion plate.

[0006] Furthermore, a notch is provided on the lower end of the wedge block, a boss corresponding to the position of the notch is provided on the support plate, a guide hole is provided on the boss, a pin is fixedly provided on the lower frame, a spring is provided on the pin, and a guide pin that can extend into the guide groove is fixedly provided on the lower frame.

[0007] When mopping, the mop head is rotated perpendicular to the mop handle. During washing and wringing, the mop head is rotated parallel to the mop handle. The mop head is then pulled by hand, allowing one end to enter the squeezing device. Pulling the mop head further to the left causes the squeezing plate on the mop head to be squeezed by the squeezing rollers in the lower frame. Simultaneously, the washing head on the squeezing plate moves to the left and is subjected to squeezing pressure between the rotating wringing rollers, the moving wringing strip, and the squeezing plate in the upper frame, thus dehydrating. During wringing, the multi-row rotating wringing rollers' rolling and surface contact design extends service life. Furthermore, the moving wringing strip, due to its movable guide arc groove structure,… As the washing head extends from the water-squeezing device under external force, the height of the moving water-squeezing strip gradually decreases, thereby gradually increasing the force exerted on the washing head by the moving water-squeezing strip. The contact surface of the lower conical section is wider, resulting in a significantly enhanced water-squeezing effect compared to the existing fixed force-bearing method. In addition, water flows from the drain groove and water guide channel to the outlet. After dehydration, reverse the handwheel, release the squeezing wheel, and push the mop handle to the right to remove the mop head from the squeezing device. During the removal process, due to the structural characteristics of the moving guide arc groove, the height of the moving water-squeezing strip gradually increases under external force, making it easier for the washing head to exit the water-squeezing device.

[0008] When the pressing wheel of the lower frame is movable, this invention utilizes the sliding of the oval-shaped driving wheel, which rotates with the handwheel within the waist-shaped driving groove on the linkage plate, to move the linkage plate by pressing the driving groove, as shown. Figure 7 As shown, when the handwheel is turned so that the upper drive wheel is on the right, the drive groove also moves to the right. At this time, the linkage plate moves to the far right, causing the wedge blocks at both ends of the linkage plate to move to the right. The support plate rises, and the squeezing wheel rises to press the squeezing plate, which is horizontally inserted into the squeezing device. By pulling the mop handle, the mop head moves horizontally, causing the cleaning head on the mop head to be squeezed and dehydrated between the squeezing plate, the wringing roller, and the moving wringing strip. When the handwheel is turned so that the upper drive wheel is on the left, the drive groove also moves to the left. At this time, the linkage plate also moves to the far left, causing the wedge blocks at both ends of the linkage plate to move to the left. The support plate descends, and the squeezing wheel descends and separates from the squeezing plate, which is horizontally inserted into the squeezing device. By pulling the handle on the mop handle, the mop head moves horizontally, causing the cleaning head on the mop head to separate from the wringing roller and the moving wringing strip before mopping. By rotating the handwheel to control the angle, the linkage plate can be moved a certain distance to the left or right. This allows the height of the squeezing rollers on the support plate to be adjusted, so that the squeezing plate can be subjected to different levels of squeezing force. Thus, the dehydration and wetness control of the washing head can be achieved.

[0009] The beneficial effects of this invention are as follows: 1. By adopting a multi-row rotating squeezing roller with rolling extrusion surface contact at different positions and a multi-directional squeezing structure with adjustable height of the moving squeezing pressure bar, the squeezing effect is significantly enhanced and it is not easily damaged during long-term use; 2. By cleverly using and utilizing the elliptical drive wheel (equivalent to a double cam) located in the drive groove of the linkage plate to drive the linkage plate to move left and right, causing the support plate on the linkage plate to move up and down, and then causing the squeezing roller on the support plate to squeeze and dehydrate the squeezing plate. The dehydration dryness and wetness can be adjusted and controlled by rotating the handwheel, and the squeezing device is durable and highly reliable. Attached Figure Description

[0012] The figure shows a multi-squeezing folding mop, which includes a mop handle 2 that can move within a sleeve 4 under external force and a mop head that is movably connected to one end of the mop handle via a connector 13. The sleeve is made of plastic tubing, and the left end of the sleeve is movably connected to the mop handle 2, which is made of stainless steel tubing. The diameter of the other end (right end) of the sleeve is larger than that of its left end (to limit the leftward movement of the mop handle during wringing). The right end of the sleeve has a web 30 spaced apart and parallel to the axis of the sleeve. The rightmost end of the sleeve has a circular limiting head 26. The upper part of the sleeve has an opening 3. The lower end of the mop handle has a limiting block 27. When the limiting block is located between the webs and moves to the limiting head (to limit the rightward movement of the mop handle during mopping), the mop handle can no longer move to the right. At this time, the mop head is vertical and in the mopping state. When the mop head becomes horizontal and enters the squeezing device, the handle 1 is pulled by hand to move the mop handle to the left, and the mop head enters the squeezing device to squeeze and dehydrate. The connector is a plastic tubular connector. The left end of the connector is fixedly fitted to the inner hole of the mop handle. The left end of the connector is fixedly connected to one end of the mop handle via a locking block 15. One end of the locking block is integrally connected to the connector, while the right end is cantilevered. Under external force, the locking block can float up and down. When connected to the mop handle, the locking block extends out of the mop handle through a window 14. Pressing down the locking block forces it out of the window, allowing the connector to be removed. Additionally, a socket (not shown in the figure) is provided at one end of the mop handle. A plate 16 matching the socket is provided on the connector (the plate prevents the connector from rotating inside the mop handle). The other end of the connector is connected to a connector head 24 via a rotating shaft 23. Connecting shafts are provided at both ends. Pin 19, connector 24, connecting pin 19 and connecting shaft 22 are integrated. The connecting pin and the pin hole 20 on the connecting protrusion 21 are slidably matched. The connecting protrusion 21 and the extrusion plate are integrated. In this way, the mop handle and the mop head can be movably connected. The right end of the connector is provided with cavity 17. The inner cavity of the cavity is larger than the outer shape of the connecting protrusion. The connector is also provided with intermediate body 18. The end of the intermediate body is connected to the connector with threaded pin 25. The other end of the intermediate body is round. When mopping, this end can contact the arc of the connecting protrusion. When the mop head is horizontal, the connecting protrusion needs to rotate around the circle of the right end of the intermediate body. The function of the cavity is that when the mop head is horizontal, the connecting protrusion on it is hidden in the cavity, so that the mop head can smoothly turn from vertical to horizontal.The mop head includes a squeezing plate 11 movably connected to a rotating shaft 23 via a connecting protrusion 21, a connecting pin 19, a connecting head 24, and a cleaning head 10 made of absorbent material such as cotton yarn or sponge, which is fixedly fitted inside the squeezing plate. The cleaning head is a rectangular flat plate. By manually turning the squeezing plate, the squeezing plate and the cleaning head 10 can be rotated from a position perpendicular to the mop handle axis to a position parallel to the mop handle axis. A water-squeezing device is provided on the handle sleeve. The water-squeezing device includes a lower frame 29 connected to the handle sleeve and an upper frame 8 movably inserted into the lower frame. The upper frame has water outlets 9 spaced apart. A support frame 7 is fixedly installed in the inner cavity of the upper frame. Several rows of rotating squeezing rollers 49 arranged in parallel are supported at both ends of the support frame. A movable squeezing strip 51 is provided. Several drainage grooves 50 are provided in a ring on the outer surface of the rotating squeezing rollers. The movable squeezing strip includes an upper square section 52 and a lower conical section 53 that are integrally formed. The width of the lower conical section gradually decreases from top to bottom. A water guiding channel 54 is provided in the movable squeezing strip that runs through the upper square section and the lower conical section. Guide rods 55 are provided at both ends of the movable squeezing strip. The guide rods are movably installed in the movable guide arc grooves 56 at both ends of the support frame. The height of the movable guide arc grooves gradually decreases from the position where the washing head extends to the position where it extends (e.g.). Figure 1(As shown from right to left), the lower frame contains axle 32 with several pressing wheels 6. These pressing wheels can be fixed or movable. When the pressing wheels are movable, the structure can be as follows: a linkage plate 28 is provided within the lower frame. The linkage plate has wedge-shaped blocks 36 at both ends. The top surfaces of the wedge-shaped blocks have the same inclination direction and angle. Rectangular (elongated) guide grooves 42 are provided opposite each other on the linkage plate between the wedge-shaped blocks. A waist-shaped drive groove 40 is provided on the wedge-shaped block between the two opposite guide grooves. A notch 44 is provided at the lower end of the wedge-shaped block (the notch width is greater than the spring diameter, and the notch depth is greater than the distance when the linkage plate moves to the right). The linkage plate and spring will not collide to ensure that the linkage plate can move smoothly to the highest position. A rotatable handwheel 39 is set in the middle of the lower frame. The handwheel is movably set in the lower frame through a disc 48. A central guide shaft 38 (equivalent to the rotating shaft of the handwheel) is set at the upper end of the center of the handwheel. The guide shaft, disc and handwheel are integrated. Offset from the center of the handwheel is an elliptical drive wheel 41 that can be movably inserted into the drive groove of the linkage plate. The drive wheel is integrated with the handwheel and is elliptical (equivalent to a double cam). The drive wheel is mounted on the support plate by a rotating shaft 23. The lower part of the drive wheel is located in the wheel groove 35 at the upper end of the support plate. The drive wheel rotates with the handwheel, and when it rotates in the drive groove, it causes the linkage plate to move left and right. A support plate 5 is provided on the wedge block. When the wedge block moves left and right with the linkage plate, it causes the support plate to move up and down (when the linkage plate and wedge block move to the right together, the support plate and the extrusion wheel rise, and the extrusion wheel presses against the extrusion plate; when the linkage plate and wedge block move to the right together, the extrusion wheel of the support plate descends, and the extrusion wheel separates from the extrusion plate). Each support plate has an extrusion wheel at an interval at its upper end that can rotate and closely adhere to the extrusion plate. The support plate has a boss 46 corresponding to the notch position, and a guide hole 31 is provided on the boss. The lower frame is fixedly mounted with... A pin 43 is movable and matches the guide hole. The lower end of the pin is a base 12, which is fixedly connected to the lower frame. A spring 45 is installed on the pin. A guide pin 37, which can extend into and slide within the guide groove, is fixedly installed on the lower frame. The diameter of the guide pin is slightly smaller than the width of the guide groove. When the support plate descends, the boss descends, compressing the spring. When the support plate rises, the boss rises, and the spring extends under the elastic force. An outer guide plate 34, which can approach the support plate, is integrally installed on the lower frame. The sleeve is integrally connected to the inner frame 33. Inner guide plates 47, which can approach the support plate, are installed on both sides of the inner frame. The inner guide plates and outer guide plates 35 are used for guiding the support plate up and down.
