Description

Technical Field

[0001] This invention relates to sanitary ware, and more particularly to a quick-folding mop for floor cleaning. Background Technology

[0002] As we all know, mops are an indispensable cleaning tool in people's work and daily life. There are many types of mops, including traditional ordinary mops made of cotton strips and wooden handles, which are wrung out by hand. As the surfaces being mopped are mostly made of floor tiles, wooden boards, or polished surfaces, the mops currently in use mainly have two types of mop heads: one type is a foot-operated mop with a mop head made of cotton strips or yarn with one end flared out, and the mop head is rotated and dried by a matching wringer; the second type is a flat rotating mop head made of sponge or cotton yarn, and the mop head is squeezed and dehydrated by a wringer on the mop. Currently, the squeezing devices on flat rotary mops still have the following problems in use: One is that the height of the squeezing wheel on the squeezing device is fixed, meaning the squeezing force applied to the mop head cannot be adjusted. Consequently, the dryness of the mop head after squeezing cannot be adjusted, resulting in incomplete dehydration and directly affecting mopping performance and efficiency. Another type, although the position of the squeezing wheel on the squeezing device can be adjusted, the adjustment mechanism uses a rotating gear to drive two inclined racks that mesh with it to move relative to each other. Due to space and cost limitations, these racks are mostly made of thin plastic sheets. After a short period of use, the racks are prone to deformation and the teeth are prone to breakage, affecting squeezing and dehydration, and may even prevent squeezing altogether. Therefore, the squeezing device is not durable or reliable. Summary of the Invention

[0003] In view of the problems existing in the squeezing device on the flat rotary mop in the above-mentioned prior art, the present invention provides an adjustable wet and dry squeezing mop that is not only compact in structure, flexible and convenient to use, with good dehydration effect and high dehydration efficiency, but also durable and reliable in squeezing device.

[0004] The technical solution adopted by this invention to solve the technical problem is: an adjustable wet / dry squeeze 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 squeeze plate movably connected to the connecting shaft via a connecting protrusion and a cleaning head fixedly fitted within the squeeze plate. The squeeze 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 fixedly connected to the lower frame. A cavity is fixedly provided within the upper frame. The wiper blade corresponds to the width of the cleaning head. A linkage plate is provided in the lower frame. The linkage plate has wedge-shaped blocks at both ends. The top surfaces of the wedge-shaped blocks are inclined in the same direction and at the same angle. The linkage plate between the wedge-shaped blocks has guide grooves facing each other. The wedge-shaped blocks between the two opposing guide grooves have waist-shaped drive grooves in the vertical direction. A rotatable handwheel is provided in the middle of the lower frame. A drive wheel that can be moved into the drive groove is provided off-center from the center of the handwheel. When the drive wheel rotates in the drive groove with the handwheel, it can move the linkage plate left and right. Support plates are provided on the wedge-shaped blocks at both ends of the linkage plate. When the wedge-shaped blocks move with the linkage plate, they can move the support plates up and down. Each support plate has a rotating extrusion wheel that can be closely attached to the extrusion plate at an interval at its upper end.

[0005] To ensure the support plate moves vertically, a notch is provided at the bottom of the wedge block, and a boss corresponding to 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.

[0006] This invention utilizes the sliding motion of an elliptical drive wheel, which rotates with the handwheel within a waist-shaped drive groove on the linkage plate, to move the linkage plate by compressing the drive groove. Figure 4 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, the extrusion wheel rises and presses against the extrusion plate, which is horizontally positioned and enters the extrusion 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 extrusion plate and the squeegee. Figure 5As shown, when the handwheel is turned so that the upper drive wheel is on the right, the drive groove also moves to the left. At this time, the linkage plate also moves to the leftmost end, 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 that has entered the squeezing device horizontally. By pulling the handle on the mop handle, the mop head moves horizontally, separating the cleaning head from the squeegee for mopping. By controlling the angle of the handwheel, the linkage plate can be moved a certain distance to the left or right. This allows the height of the squeezing wheel on the support plate to be adjusted, so that the squeezing plate can be subjected to different amounts of squeezing force, thus enabling control of the drying and dehydration of the cleaning head.

[0007] In this invention, when mopping, the mop head is rotated to be perpendicular to the mop handle. When washing and wringing, the mop head is rotated to be parallel to the mop handle. The mop head is pulled by hand so that the mop-shaped end enters the squeezing device. The mop head is then pulled to the left so that the squeezing plate on the mop head is squeezed by the squeezing wheel. As the washing head on the squeezing plate moves to the left, it is squeezed between the squeegee and the squeezing plate to wring out the water. After wringing, the handwheel is reversed to release the squeezing wheel, and the mop handle is pushed to the right to remove the mop head from the squeezing device.

[0008] This invention ingeniously utilizes an elliptical drive wheel (equivalent to a double cam) located within the drive groove on the linkage plate to move the linkage plate left and right, thereby causing the support plate on the linkage plate to move up and down. The extrusion wheel on the support plate then extrudes and dehydrates the extrusion plate. It is not only compact and easy to use, but also provides excellent dehydration effect and high efficiency. The dryness and wetness of the washing head can be adjusted and controlled by rotating the handwheel, and the extrusion device is durable and highly reliable. Attached Figure Description

[0011] In the figure, an adjustable wet / dry squeeze mop includes a mop handle 2 that can move within a handle 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 handle sleeve is made of plastic tubing, and the left end of the handle 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 handle sleeve is larger than that of its left end (serving to limit the leftward movement of the mop handle during wringing). The right end of the handle sleeve is provided with a web plate 30 parallel to the axis of the handle sleeve at intervals. The rightmost end of the handle sleeve is provided with a circular limiting head 26. The upper part of the handle sleeve is provided with an opening 3. The lower end of the mop handle is provided with a limiting block 27. When the limiting block is located between the web plates and moves to the limiting head (serving 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 in a vertical position and is 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 connecting head 24 via a rotating shaft 23. Connecting shafts have connecting... 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 fixedly connected to the lower frame with screws. Water outlets 9 are spaced apart on the upper frame. A grid-shaped squeegee 7 corresponding to the width of the cleaning head is fixedly installed in the inner cavity of the upper frame. A linkage plate 28 is provided in the lower frame. The linkage plate has two... The end has a wedge-shaped block 36, the top surface of the wedge-shaped block has the same inclination direction and angle, and the linkage plate between the wedge-shaped blocks has a rectangular (long waist-shaped) guide groove 42 facing each other. The wedge-shaped block between the two opposing guide grooves has a waist-shaped drive groove 40 in the vertical direction. The lower end of the wedge-shaped block has a notch 44 (the notch width is greater than the spring diameter, and the notch depth is greater than the spring diameter). When the linkage plate moves to the right, the linkage plate and the spring will not collide, so as to ensure that the linkage plate can move smoothly left and right and that the support plate on the linkage plate can move vertically up and down. The lower frame has a rotatable handwheel 39 in the middle. The handwheel is movably set in the lower frame through a disc 48 in the middle. The upper end of the center of the handwheel has a middle guide shaft 38 (equivalent to the rotating shaft of the handwheel). The disc and handwheel are integrated. An elliptical drive wheel 41, offset from the center of the handwheel, is movably inserted into a drive groove on 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 a support plate via an axle 32, on which a pressing wheel 6 is mounted. The lower part of the drive wheel is located within a groove 35 at the upper end of the support plate, allowing it to rotate with the handwheel within the drive groove. When the drive wheel rotates with the handwheel within the drive groove, it causes the linkage plate to move left and right. A support plate 5 is mounted 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 pressing wheel rise, and the pressing wheel presses against the pressing plate; the linkage plate...). When the support plate moves to the right along with the wedge block, the extrusion rollers of the support plate descend (separating from the extrusion plate). Each support plate has rotatable extrusion rollers at intervals on its upper end that can closely adhere to the extrusion plate. Each support plate has a boss 46 corresponding to the notch position, and a guide hole 31 is provided on the boss. A pin 43, which movably matches the guide hole, is fixedly provided on the lower frame. The lower end of the pin is a base 12, which is fixedly connected to the lower frame. A spring 45 is provided on the pin. A guide pin 37, which can extend into and slide within the guide groove, is fixedly provided 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, stretching the spring.The lower frame is integrally provided with an outer guide plate 34 that can approach the support plate. The rod sleeve is integrally connected with the inner frame 33. The inner frame is provided with inner guide plates 47 that can approach the support plate on both sides. The inner guide plates and outer guide plates 35 are used to guide the support plate up and down.
