A folded extruded water wrung cellulose mop

Abstract

This invention provides a folded and squeeze-dry sponge mop, comprising a mop handle and a mop head. The mop head includes a connecting plate and first squeezing plates rotatably mounted on both sides of the connecting plate. A sponge head is mounted on the bottom of the first squeezing plate. The mop handle is provided with a vertically movable squeezing frame. Moving the squeezing frame downwards causes the first squeezing plate to rotate downwards and squeeze the sponge head. Further downward movement of the squeezing frame pushes a second squeezing plate relative to the first squeezing plate, causing the second squeezing plate to extend beyond the first squeezing plate and squeeze the end of the sponge head. This invention has the advantage of utilizing the movement of the squeezing frame along the mop handle to drive the first squeezing plate downwards, folding the sponge head in half and squeezing it dry; the downward movement of the squeezing frame pushes the second squeezing plate to extend beyond the first squeezing plate to cover the end of the sponge head; and the combined action of the first and second squeezing plates to squeeze the sponge head dry as a whole.

Description

Technical Field

[0001] This invention relates to the field of mops, and more specifically to a PVC mop that can be folded in half and squeezed dry. Background Technology

[0002] A sponge mop is a common floor cleaning tool, mainly consisting of a mop handle, a squeezing frame, a squeezing plate, and a sponge head. The squeezing plate and sponge head are folded together by a handle attached to the top of the mop handle, squeezing the sponge head dry. Existing sponge mops have a U-shaped squeezing frame, connecting the mop handle and squeezing plate at the top and bottom respectively. This makes the lower part of the sponge mop wider and heavier, resulting in a cumbersome design that makes it difficult to reach into crevices for cleaning.

[0003] To address the aforementioned issues, Chinese patent CN211243210U discloses a folding PVA mop. This patent improves the wringing mechanism, eliminating the complex wringing structure such as the pull rod compared to traditional folding PVA mops, making the mop lighter, more aesthetically pleasing, and easier to install. However, in typical folding PVA mops, the ends of the PVA head extend from the end of the extrusion plate to prevent the extrusion plate from hitting tables, chairs, or walls. Although this PVA mop improves the wringing mechanism, it still doesn't solve the problem of how to squeeze the PVA head dry. Summary of the Invention

[0004] One object of the present invention is to provide a folded and wringed cotton mop that solves the above-mentioned problems.

[0005] To achieve the above-mentioned objectives, the present invention is implemented through the following technical solutions: A folding and wringing sponge mop includes a mop handle and a mop head. The mop head includes a connecting plate and first wringing plates rotatably mounted on both sides of the connecting plate. The connecting plate is connected to the mop handle. A sponge head is mounted on the bottom of the first wringing plate. The mop handle is provided with a wringing frame that can move up and down along the mop handle. When the wringing frame moves downward, it can push the first wringing plate downward to rotate and squeeze the sponge head. A second wringing plate is provided on the side of the first wringing plate away from the connecting plate. When the wringing frame continues to move downward, it can push the second wringing plate to move relative to the first wringing plate, so that the second wringing plate extends out of the first wringing plate and squeezes the end of the sponge head. The traditional wringer is adjusted to be movable up and down and mounted on the mop handle, making the lower end of the mop lighter. The wringer moves up and down along the mop handle, causing the first wringer plate to rotate downwards, folding the cotton head in half and squeezing it dry. The downward movement of the wringer pushes the second wringer plate to extend out of the first wringer plate and cover the end of the cotton head. The first and second wringer plates work together to squeeze the cotton head dry as a whole.

[0006] Preferably, the wringer has a wringing opening through which the mop head and the sponge head can be folded and passed. The wringer has a first support extending into the wringing opening, and a pusher on the second wringer plate. During wringing, the first wringer plate rotates to a state substantially parallel to the mop handle, and the first support moves downward to contact the pusher, causing the second wringer plate to move downward and extend synchronously. By providing a first support on the wringer and a pusher on the second wringer plate, during the wringing process, the first support automatically engages with the pusher when the wringer moves down to a preset position, enabling the second wringer plate to squeeze and dehydrate the end of the sponge head. This makes it more convenient to use, eliminating the need for separate operation to control the movement of the second wringer plate.

[0007] Preferably, the pusher head protrudes upward from the top of the second dewatering plate. During dewatering, the first support portion slides across the top surfaces of the first and second dewatering plates until it contacts and engages with the pusher head. With the pusher head protruding upward, the first and second dewatering plates do not obstruct the movement of the first support portion during the movement of the dewatering frame. The first support portion can engage with the first and second dewatering plates by sliding against them or by passing through the gap between them, until the first support portion moves to a position where it abuts against the pusher head.

[0008] Preferably, the first and second wringer plates are provided with communicating grooves, and the pusher head is disposed in the groove. During wringing, the first support portion extends into the groove and moves along the groove until it contacts and engages with the pusher head. The groove design ensures that the first pusher head remains within the groove during its up-and-down movement, resulting in smoother movement. Furthermore, the side walls of the groove can limit the relative movement of the first support portion and the mop head, preventing the mop head and wringer from wobbling or tilting due to lateral gaps.

[0009] Preferably, the first support portion rests on the first or second wringer plate to squeeze the cotton head, and / or the wringer frame is further provided with a second support portion, which rests on the top surface of the first or second wringer plate to squeeze the cotton head. Meanwhile, compared to the surface contact and push-top contact of the wringer frame, the first and second support portions convert surface contact into point or line contact, reducing the contact area between the wringer frame and the mop head, reducing movement resistance, and making the up-and-down movement of the wringer frame more effortless.

[0010] Preferably, the first squeezing plate has a recessed step at its end, and the second squeezing plate is fitted onto the step to keep the surfaces of the first and second squeezing plates flush. The first squeezing plate has a slot, and the second squeezing plate has a rod. During installation, the rod is inserted into the slot and can move within the slot. A limiting part is provided between the rod and the slot to limit the length of the second squeezing plate extending from the end of the first squeezing plate. The recessed step keeps the top surfaces of the first and second squeezing plates flush, and the fit between the first or second support part and the first and second squeezing plates is smoother when the first or second support part moves up and down, preventing any jerking or jamming caused by the height difference of the top surfaces during installation. When the first and second support parts move to the position of the second squeezing plate, they indirectly abut against the first squeezing plate located inside the second squeezing plate by abutting against the second squeezing plate. Even if the length of the first and second support parts is shortened to only support the outside of the second squeezing plate, the entire cotton head can still be compressed.

[0011] Preferably, the top of the sponge head is provided with a mounting plate, and the bottom of the first wringer is open. The mounting plate can be inserted into the bottom opening of the first wringer for installation. The first wringer is provided with a first support rib, which is attached to the top surface of the mounting plate to support the mounting plate in squeezing the sponge head. During mopping and wringing, the first support rib always rests against the top surface of the mounting plate, thereby preventing the flexible sponge head from sinking into the wringer.

[0012] Preferably, the first dewatering plate has a first enclosure around its outer periphery, and the second dewatering plate has a second enclosure around its outer periphery. The first enclosure and the second enclosure surround the outer periphery of the mounting plate. The portion of the second dewatering plate extending beyond the first dewatering plate has a second supporting rib. There is a height difference between the bottom surfaces of the first and second supporting ribs and the bottom surfaces of the first and second enclosures. A transition surface is provided between the bottom surface of the second supporting rib and the second enclosure at the end position of the second dewatering plate. Alternatively, the second enclosure at the end position of the second dewatering plate has a clearance opening to prevent the end of the cotton head from obstructing the reset movement of the second dewatering plate. When the PVC foam head is installed, its top surface is in contact with the first and second enclosures. When the PVC foam head is squeezed dry, the second squeezing plate moves along the top surface of the PVC foam head, extends and squeezes the end of the PVC foam head, so that the end of the second enclosure and the side of the PVC foam head have an overlapping area. If a step is formed between the second enclosure and the second support rib at this position due to the height difference, the end of the PVC foam head will sink into the step, which will hinder the reset movement of the second squeezing plate. The setting of the transition surface and the clearance opening can effectively avoid the end of the PVC foam head from hindering the reset movement of the second squeezing plate.

[0013] Preferably, a spring is provided between the first wringer plate and the second wringer plate. When the second wringer plate is disengaged from the support of the first support, the elastic force of the spring causes the second wringer plate to automatically reset. The first wringer plate and the connecting plate are connected by a rotating shaft. A torsion spring is provided on the rotating shaft. When the mop head moves downward and disengages from the wringer frame, the elastic force of the torsion spring causes the first wringer plate to automatically reset and rotate to the mopping state.

[0014] Preferably, a first drainage channel is provided between the first support rib and the first enclosure, or between two first support ribs; a water passage hole is provided at the end of the first wringer; a second drainage channel is provided between the second support rib and the second enclosure, or between two second support ribs; and a drainage hole is provided in the second enclosure. The first drainage channel, the water passage hole, the second drainage channel, and the drainage hole are connected, allowing water from the cleaning or squeezing of the sponge head to flow downwards and exit through the drainage hole. When the sponge head is rinsed at a faucet or soaked in a mop bucket, water enters the cavity between the mop head and the sponge head. Even water squeezed out from the area where the sponge head is not fitted with a mounting plate during wringing can enter the cavity between the mop head and the sponge head. The arrangement of the first drainage channel, the water passage hole, the second drainage channel, and the drainage hole ensures that when the mop head and the sponge head are folded and moved, the drainage path is vertical or inclined, facilitating the downward drainage of water within the cavity due to gravity and preventing the sponge head from reabsorbing the water and affecting the wringing effect.

[0015] Preferably, the wringer also includes a handle and a wringer cylinder. The wringer cylinder has a squeezing chamber for the mop head and the sponge head to be folded in half and inserted. The wringer cylinder has a wringing nozzle at its bottom, allowing the sponge mop to be placed upright in a horizontal position through the bottom of the wringing nozzle. The top of the wringer cylinder and the side of the wringing nozzle have upper and lower vent holes, respectively. The upper vent hole, the squeezing chamber, and the lower vent hole form a circulating air duct that connects to the outside. The wringer cylinder allows the mop head and sponge head to be folded in half and stored inside, and the mop to be placed upright, reducing the overall packaging, transportation, and storage volume of the mop. The circulating air duct also improves ventilation within the wringer cylinder, allowing outside air to circulate from top to bottom or bottom to top. Even when the wringer cylinder is placed with the wringing nozzle touching the ground and closed, the circulating air duct still maintains good ventilation, ensuring that the wringer cylinder itself or the sponge head stored within it can be air-dried.

[0016] The advantages of this invention are as follows: The traditional wringer is adjusted to be movable up and down on the mop handle, making the lower end of the mop lighter. The wringer's movement along the mop handle drives the first wringer plate downwards, folding the cotton head in half to squeeze it dry. The downward movement of the wringer pushes the second wringer plate out from the first wringer plate to cover the end of the cotton head. The first and second wringer plates work together to squeeze the cotton head dry as a whole. By providing a first support on the wringer and a pusher on the second wringer plate, during the wringing process, the wringer moves down to a preset position, and the first support automatically engages with the pusher to squeeze and dehydrate the end of the cotton head with the second wringer plate. This makes it more convenient to use, eliminating the need for separate operation to control the movement of the second wringer plate. Attached Figure Description

[0041] like Figure 1-22 A folding and wringing sponge mop includes a mop handle 1 and a mop head 2. The mop head 2 includes a connecting plate 3 and a first wringing plate 4 rotatably mounted on both sides of the connecting plate 3. The connecting plate 3 is connected to the mop handle 1. A sponge head 5 is installed at the bottom of the first wringing plate 4. A wringing frame 6 is provided on the mop handle 1 and can move up and down along the mop handle 1. The wringing frame 6 can move downward to push the first wringing plate 4 and drive the first wringing plate 4 to rotate downward to squeeze the sponge head 5. A second wringing plate 7 is provided on the side of the first wringing plate 4 away from the connecting plate 3. The wringing frame 6 can continue to move downward to push the second wringing plate 7 relative to the first wringing plate 4, so that the second wringing plate 7 extends out of the first wringing plate 4 and squeezes the end of the sponge head 5.

[0042] In this embodiment, as Figure 2 The mop head 2 is directly connected to the mop handle 1, and the wringer 6 is installed on the mop handle 1. Compared with the traditional folding sponge mop, there is no connection between the wringer 6 and the mop head 2, but only a mutual cooperation relationship. The wringer 6 can be positioned at a high position on the mop handle 1, making the connection point between the mop head 2 and the mop handle 1 lighter and with fewer parts, making it easier for the mop head 2 to enter crevices for cleaning.

[0043] Preferably, the mop head 2 and the mop handle 1 can be installed using a fixed connection or a rotating connection. When using a fixed connection, the shape of the sponge head 5 adopts the shape of a traditional folding sponge mop, that is, the cross-section of the sponge head 5 is semi-circular or arc-shaped. When cleaning, the mop handle 1 is tilted, and the two sides of the sponge head 5 are in contact with the ground for cleaning. When using a rotating connection, the shape of the sponge head 5 adopts the shape of a flat mop, that is, the sponge head 5 is a flat sheet or plate. The rotating connection between the mop handle 1 and the mop head 2 allows the bottom surface of the sponge head 5 to always be in contact with the ground for cleaning. It should be noted that in this embodiment, regardless of the connection method between the mop head 2 and the mop handle 1, or the shape of the sponge head 5, the support and squeezing method of the wringer 6 for the mop head 2 and the sponge head 5 is the same. Only adaptive adjustments are needed according to the different shapes and sizes of the mop head 2 and the sponge head 5.

[0044] In this embodiment, the mop handle 1 and mop head 2 are rotatable along one of their planes, and the sponge head 5 is illustrated with an arc-shaped cross-section. Specifically, as shown... Figure 2-6 The two sides of the connecting plate 3 are rotatably connected to a first wringer plate 4 via a rotating shaft 8. The two first wringer plates 4 are fixedly installed at different positions with the cotton head 5. Under external force, the two first wringer plates 4 can rotate downwards and cause the cotton head 5 to bend downwards. The bottom of the wringer frame 6 is provided with a wringer opening 9 through which the mop head 2 can be bent and passed. Figure 2 When mopping, the mop head 2 and the sponge head 5 are extended horizontally and at an angle perpendicular to or inclined to the mop handle 1, such as... Figure 3-6 When the mop head is in the wringing state, push the wringing frame 6 downwards until the wringing nozzle 9 is against the top of the first wringing plate 4. The wringing frame 6 continues to move downwards, and the first wringing plate 4, located off the pivot 8, is pushed downwards by the wringing frame 6 and rotates downwards. At the same time, the flexible sponge head 5 bends and deforms downwards, reducing the lateral dimension of the mop head 2. The connecting plate 3, the first wringing plate 4 in the middle, and the sponge head 5 pass upwards through the wringing nozzle 9. Under the support of the wringing frame 6, the mop head 2 and the sponge head 5 form a U-shape. As the wringing frame 6 continues to move downwards, the first wringing plate 4 continues to rotate downwards until the mop head 2 and the sponge head 5 pass through the wringing nozzle 9 as a whole. At this time, if... Figure 7-9The first wringer plate 4 rotates to a position roughly parallel to the mop handle 1. The sponge head 5 at the bottom, positioned between the two wringer plates 4, rotates with the first wringer plate 4. The outer side of the first wringer plate 4 is directly or indirectly supported by the wringer frame 6. The sponge head 5 is squeezed and deformed by the two wringer plates 4, squeezing out the water. After squeezing, the wringer frame 6 is pulled upwards, gradually moving away from the mop head 2. Under the elastic force of the sponge head 5 itself, or by installing a torsion spring 10 on the rotating shaft 8, the first wringer plate 4 gradually rotates upwards to reset until the wringer frame 6 is completely detached from the mop head 2. The first wringer frame 6 rotates to a position perpendicular to the mop handle 1, causing the sponge head 5 to unfold.

[0045] Preferred, such as Figure 2 The size of the connecting plate 3 is larger than the diameter of the mop handle 1 and smaller than the inner width of the squeezing nozzle 9, so that the connecting plate 3 passes through the squeezing nozzle 9 as a whole. At the same time, the plane where the rotating shaft 8 is located is located in the squeezing nozzle 9, so that the squeezing frame 6 abuts against the first squeezing plate 4 at a position away from the rotating shaft 8. The first squeezing plate 4 can rotate downward and pass through the squeezing nozzle 9 upward.

[0046] To prevent the mop head 2 from bumping into tables, chairs, or walls while mopping, in this embodiment, the lengths of the mop head 2 and the sponge head 5 are such that the length of the sponge head 5 is greater than the length of the mop head 2. Figure 2 and 4 When mopping, the two ends of the sponge head 5 extend from the two ends of the first wringer 4. Since the squeezing of the sponge head 5 is achieved by the support and squeezing of the first wringer 4, the outer part of the sponge head 5 that extends beyond the first wringer 4 is not supported by the first wringer 4. Moreover, this part of the sponge head 5 is located at the bottom during the squeezing operation. The water in this part of the sponge head 5 is difficult to squeeze out, and it will also absorb the water squeezed out by the upper sponge head 5. The second wringer 7 is set so that the overall length of the sponge head 5 and the first wringer 4 are changed during the squeezing operation to cover the end position of the sponge head 5, thereby squeezing out the protruding part of the sponge head 5.

[0047] Specifically, the dewatering rack 6 is provided with a first support part 11, and the second dewatering plate 7 is provided with a pusher top 12. The second dewatering plate 7 moves and extends through the abutting cooperation between the first support part 11 and the pusher top 12. Figure 3The first support part 11 can be the surface of the side of the wringer 9 or a separate component on the wringer frame 6. When the surface of the side of the wringer 9 forms the first support part 11, the top surface of the first wringer plate 4 directly contacts the side surface of the wringer 9. The movement resistance between the first wringer plate 4 and the side of the wringer 9 is relatively large, and the top surface of the first wringer plate 4 is easily scratched, affecting the appearance. At the same time, the push top 12 needs to be set as a structure that protrudes from the top of the second wringer plate 7. The second wringer plate 7 is moved and extended by pushing the push top 12 against the bottom through the wringer 9. At this time, the second wringer plate 7 and the cotton head 5 located outside the push top 12 cannot enter the wringer 9 upward. The cotton head 5 located below the wringer 9 cannot be completely squeezed dry because it is not supported by the wringer frame 6 on both sides. In addition, this part of the second wringer plate 7 and the cotton head 5 will prevent the cotton mop from being placed upright on the ground.

[0048] like Figure 2-6 9. In this embodiment, the first support part 11 is a separate component on the wringer 6 and extends laterally into the wringer opening 9. To reduce the moving resistance between the first support part 11 and the first wringer plate 4 and the second wringer plate 7, the first support part 11 is configured as a vertically extending sheet or rib, so that the first support part 11 forms a line contact or a small area surface contact with the first wringer plate 4 and the second wringer plate 7, thereby reducing the moving resistance. Of course, in order to allow both the mop head 2 and the sponge head 5 to pass upward through the wringer opening 9, there is a height difference between the first support part 11 and the bottom of the wringer 6, and the first support part 11 is located above the bottom of the wringer opening 9. This height difference provides space for the second wringer plate 7 to move and extend, and allows the moving and extending second wringer plate 7 and the squeezed and deformed end of the sponge head 5 to remain within the wringer opening 9 and be squeezed. The bottom of the wringer 6 is still located at the bottom of the overall sponge mop, and it can be placed upright on the ground for storage.

[0049] Based on the first support part 11 being set as a sheet or rib, the push top 12 can also be set in various forms depending on the position of the first support part 11.

[0050] The first type, such as Figure 10The push top 12 protrudes upward from the top of the second wringer 7, and the wringer frame 6 moves downward to the position where the first support part 11 and the push top 12 cooperate. The first support part 11 pushes the push top 12 to move downward, causing the second wringer 7 to move and extend. In the initial stage of the downward movement of the wringer frame 6, the first wringer 4 and the second wringer 7 can be rotated downward by the side surface of the wringer nozzle 9 against it. The first support part 11 does not contact the first wringer 4 and the second wringer 7, but only passes over the top surface of the first wringer 4 and the second wringer 7. Alternatively, the side surface of the wringer nozzle 9 can first rotate the first wringer 4 and the second wringer 7 downward to a smaller angle. As the middle part of the mop head 2 enters the wringer nozzle 9 upward, the first support part 11 then abuts against the top surface of the first wringer 4 and the second wringer 7, causing the first wringer 4 and the second wringer 7 to rotate further downward.

[0051] The second type, such as Figure 5-6 9. The first squeezing plate 4 and the second squeezing plate 7 are provided with a connecting groove 13. The groove 13 extends along the length of the mop head 2. The push top 12 is located in the groove 13. When squeezing water, the first squeezing plate 4 and the second squeezing plate 7 can also adopt the structure of being pushed down and rotated by a certain angle by the side surface of the squeezing port 9 until the first support part 11 is inserted into the groove 13 and squeezes the first squeezing plate 4 and the second squeezing plate 7 to rotate further down. The first support part 11 moves along the groove 13 to the position of the push top 12 and cooperates with the push top 12 to push the second squeezing plate 7 to move down and extend. Based on this structure, the chute 13 and the push top 12 can be set on the top surface or corner of the first wringer plate 4 and the second wringer plate 7. With the chute 13 and the first support 11 cooperating, the chute 13 and the first support 11 can restrict the relative up and down movement of the wringer frame 6 and the mop head 2, so as to avoid the movement and shaking or deviation from the preset mode caused by the activity gap between the mop head 2 and the wringer frame 6, and make the relative movement between the mop head 2 and the wringer frame 6 more stable.

[0052] In the above embodiment, the downward rotation of the mop head 2 folds the first support part 11 to achieve the top. The first support part 11 provides support force on the outer side of the first wringer 4 and the second wringer 7, so that the cotton head 5 is folded and squeezed to remove water. In order to improve the squeezing effect of the cotton head 5, a second support part 14 can be provided on the wringer frame 6. The second support part 14 is located at a different position from the first support part 11 and can be supported at different positions of the first wringer 4 and the second wringer 7. For example, the second support part 14 is attached to the top surface of the first wringer 4 and the second wringer 7 and supports the first wringer 4 and the second wringer 7 to squeeze the cotton head 5 dry.

[0053] Preferred, such as Figure 10-11The second support portion 14 also extends into the squeezing nozzle 9. The depth to which the first support portion 11 and the second support portion 14 extend into the squeezing nozzle 9 can be set to be different, or even the first support portion 11 and the second support portion 14 can extend into the squeezing nozzle 9 at different angles, so that the first support portion 11 only has the function of cooperating with the push top 12, and the first support portion 11 no longer provides squeezing support for the first squeezing plate 4 and the second squeezing plate 7. The second support portion 14 extends downward to the bottom of the squeezing frame 6. After the squeezing frame 6 moves downward, it directly pushes the first squeezing plate 4 and the second squeezing plate 7 downward through the bottom of the second support portion 14.

[0054] In this embodiment, the upper and lower ends of the second support part 14 are provided with guide surfaces 15 to facilitate the mop head 2 to enter and exit the wringer 9.

[0055] The following details the installation and assembly structure of the first dewatering plate 4 and the second dewatering plate 7. Specifically, as follows... Figure 15-17 The first dewatering plate 4 has a recessed step 16 at its end. The second dewatering plate 7 is fitted onto the step 16 so that the surfaces of the first dewatering plate 4 and the second dewatering plate 7 are flush. The first dewatering plate 4 has a slot 17, and the second dewatering plate 7 has a rod 18. During installation, the rod 18 is inserted into the slot 17 and can move within the slot 17. A limiting part 19 is provided between the rod 18 and the slot 17 to limit the length of the second dewatering plate 7 that extends from the end of the first dewatering plate 4. The recessed step 16 ensures that the top surfaces of the first wringer plate 4 and the second wringer plate 7 are flush. When the first support part 11 or the second support part 14 moves up and down, the fit between it and the first wringer plate 4 and the second wringer plate 7 is smoother. There will be no jerking or jamming caused by the height difference of the top surfaces during installation. When the first support part 11 and the second support part 14 move to the position of the second wringer plate 7, the first support part 11 and the second support part 14 indirectly abut against the first wringer plate 4 located inside the second wringer plate 7 by abutting against the second wringer plate 7. Even if the length of the first support part 11 and the second support part 14 is shortened to only support the outside of the second wringer plate 7, the cotton head 5 can still be squeezed as a whole.

[0056] The top of the cotton head 5 is provided with an installation plate 20, and the bottom of the first wringer 4 is open. The installation plate 20 can be inserted into the bottom opening of the first wringer 4 for installation. The first wringer 4 is provided with a first support rib 21, which fits against the top surface of the installation plate 20 to support the installation plate 20 to squeeze the cotton head 5 and prevent the cotton head 5 from sinking into the gap of the first wringer 4 when mopping or wringing.

[0057] In this embodiment, a first enclosure 22 is provided on the outer periphery of the first dewatering plate 4, and a second enclosure 23 is provided on the outer periphery of the second dewatering plate 7. The first enclosure 22 and the second enclosure 23 surround the outer periphery of the mounting plate 20. A second support rib 24 is provided on the part of the second dewatering plate 7 that extends out of the first dewatering plate 4. There is a height difference between the bottom surface of the first support rib 21 and the second support rib 24 and the bottom surface of the first enclosure 22 and the second enclosure 23. A transition surface 25 is provided between the bottom surface of the second support rib 24 and the second enclosure 23 at the end position of the second dewatering plate 7, or a clearance opening 26 is provided on the second enclosure 23 at the end position of the second dewatering plate 7 to prevent the end of the cotton head 5 from obstructing the reset movement of the second dewatering plate 7. When the cotton head 5 is installed, its top surface is in contact with the first enclosure 22 and the second enclosure 23. When the cotton head 5 is squeezed dry, the second squeezing plate 7 moves along the top surface of the cotton head 5 and extends to squeeze the end of the cotton head 5, so that the second enclosure 23 at the end overlaps with the side of the cotton head 5. If a step 16 is formed between the second enclosure 23 and the second support rib 24 at this position due to the height difference, the end of the cotton head 5 will sink into the step 16, which will hinder the reset movement of the second squeezing plate 7. The transition surface 25 and the relief opening 26 can effectively avoid the end of the cotton head 5 from hindering the reset movement of the second squeezing plate 7.

[0058] Preferably, a spring 27 is provided between the first wringer plate 4 and the second wringer plate 7. When the second wringer plate 7 is disengaged from the support of the first support part 11, the elastic force of the spring 27 causes the second wringer plate 7 to automatically reset. The first wringer plate 4 and the connecting plate 3 are connected by a rotating shaft 8, on which a torsion spring 10 is provided. When the mop head 2 moves downward and disengages from the wringer frame 6, the elastic force of the torsion spring 10 causes the first wringer plate 4 to automatically reset and rotate to the mopping state. Of course, the spring 27 and torsion spring 10 in this embodiment are only examples. Other devices that generate elastic force to provide the automatic reset effect are also protected by this invention. For example, the spring 27 and torsion spring 10 can be replaced with elastic materials such as soft rubber or rubber, or elastic elements such as rubber bands or elastic bands that can be stretched to generate elastic force.

[0059] In this embodiment, the sponge mop is generally cleaned by rinsing with a tap or soaking in a basin such as a mop bucket. Because there is a gap between the mop head 2 and the sponge head 5, water will enter the gap during cleaning, or when the sponge head 5 is folded and squeezed dry, water will enter the gap from the position where the mounting plate 20 is not installed. In order to facilitate the timely drainage of water in the gap, a first drainage channel 28 is provided between the first support rib 21 and the first enclosure 22, or between two first support ribs 21. A water passage hole 29 is provided at the end of the first squeezing plate 4. A second drainage channel 30 is provided between the second support rib 24 and the second enclosure 23, or between two second support ribs 24. A drainage hole 31 is provided in the second enclosure 23. The first drainage channel 28, the water passage hole 29, the second drainage channel 30 and the drainage hole 31 are connected, and the water from cleaning or squeezing the sponge head 5 can flow downwards and flow out from the drainage hole 31.

[0060] In the above embodiments, the connection structure and mating method of the first dewatering plate 4 and the second dewatering plate 7 on both sides of the connecting plate 3 are the same.

[0061] In this embodiment, the wringer 6 also includes a handle 32 and a squeezing cylinder 33. The squeezing cylinder 33 is provided with a squeezing chamber 34 for the mop head 2 and the sponge head 5 to be folded in half and inserted. The bottom of the squeezing cylinder 33 is provided with a squeezing port 9. The sponge mop can be placed upright in a horizontal position through the bottom of the squeezing port 9. The top of the squeezing cylinder 33 and the side of the squeezing port 9 are respectively provided with an upper vent 35 and a lower vent 36. The upper vent 35, the squeezing chamber 34 and the lower vent 36 form a circulating air duct that connects to the outside. The design of the squeezing cylinder 33 allows the mop head 2 and the sponge head 5 to be folded and stored inside the squeezing cylinder 33, and the mop to be placed upright, reducing the overall packaging, transportation and storage volume of the mop. In addition, the design of the circulating air duct improves the ventilation effect inside the squeezing cylinder 33, allowing outside air to circulate from top to bottom or bottom to top. Even when the squeezing nozzle 9 is placed against the ground and closed, the circulating air duct can still maintain a good ventilation effect, allowing the squeezing cylinder itself or the sponge head 5 stored in the squeezing cylinder to breathe and dry.

[0062] Preferably, both the handle 32 and the squeezing cylinder 33 are tubes that run vertically through the body and are installed around the outside of the mop handle 1. The size of the handle 32 is smaller than the size of the squeezing cylinder 33. The folded mop head 2 and the sponge head 5 enter the squeezing chamber 34, and the sides are completely surrounded and covered by the squeezing cylinder 33. When the sponge mop is squeezed dry, it is usually in an inclined state. The squeeze cylinder 33 with its side closed can guide the squeezed water to flow obliquely downward to the squeezing port 9 and out, thus preventing water from flowing out from the side of the squeezing cylinder 33 when it is folded and squeezed dry.

[0063] In this embodiment, the handle 32 and the extrusion cylinder 33 are separately set and fixedly connected as a whole, thereby reducing the production difficulty of the dewatering frame 6.

[0064] Preferably, the bottom of the extrusion cylinder 33 is provided with an outwardly opening 37, which facilitates the movement of the mop head 2 and makes the overall sponge mop more stable when placed upright.

[0065] To prevent the wringer 6 from rotating circumferentially relative to the mop handle 1 and to limit the vertical movement range of the wringer 6, a guide groove 38 is provided on the inner side of the handle 32, and a guide member 39 is provided on the outer side of the mop handle 1. When the wringer 6 is installed on the mop handle 1, the guide member 39 is inserted into the guide groove 38. The guide groove 38 extends along the axial direction of the mop handle 1 to limit the wringer 6 from rotating circumferentially relative to the mop handle 1. The end of the guide groove 38 is provided with a slot that can cooperate with the guide member 39 to position the wringer 6 in a high or low position.

[0066] In this embodiment, the cotton head 5 is detachably mounted on the first wringer 4 via the mounting plate 20. Specifically, the first wringer 4 is provided with a first fixing part 40 and a second fixing part 41, and the mounting plate 20 is provided with a first mounting part 42 and a second mounting part 43. When the first wringer 4 and the mounting plate 20 are fixedly installed, the first fixing part 40 and the first mounting part 42 are positioned vertically, and the second fixing part 41 and the second mounting part 43 are positioned horizontally. A quick-release mechanism 44 is provided, which includes a push rod 45. The push rod 45 is connected to the mounting plate 20 through an elastic section 46. The elastic section 46 arches upward to form a deformation zone 47 between itself and the mounting plate 20. The push rod 45 can drive the elastic section 46 to deform towards the deformation zone 47, causing the second mounting part 43 to move vertically and release the second fixing part 41 from vertical positioning. The first fixing part 40 separates from the first mounting part 42, allowing the cotton head 5 to be removed from the first wringer 4 in the horizontal direction.

[0067] Because the mounting plate 20 and the first dewatering plate 4 are both limited in the vertical and horizontal directions, even if the cotton head 5 or the first dewatering plate 4 is bumped during daily use, the cotton head 5 is unlikely to fall off the first dewatering plate 4.

[0068] The mounting plate 20 is made of a thin plastic sheet. The push rod 45 and the elastic segment 46 are integrally formed with the mounting plate 20. The elastic segment 46 is a thin sheet that arches upwards. The push rod 45 is located at the top of the elastic segment 46. Below the push rod 45, that is, at the angle between the elastic segment 46 and the mounting plate 20, a deformation zone 47 is formed. When subjected to external force, the elastic segment 46 deforms downwards into the deformation zone 47 to drive the push rod 45 to move downwards. The second mounting part 43 can be a component mounted on the push rod 45 or the elastic segment 46, or a part of the push rod 45 or the elastic segment 46 can form the second mounting part 43. In other embodiments, the elastic segment 46 can also be set as a separate elastic sheet, which is fixedly connected to the first dewatering plate 4 by means of glue, screws, etc.

[0069] To make the elastic segment 46 more easily deformed under stress, a deformation hole 48 is provided between the elastic segment 46 and the mounting plate 20, so that the elastic segment 46 and the mounting plate 20 are partially connected and partially independent. When the elastic segment 46 is subjected to large deformation under stress, the elastic segment 46 can pass through the deformation hole 48 and drive the cotton head 5 below to deform.

[0070] Preferably, the quick-release mechanism 44 can be controlled by directly pushing the push rod 45 to move, or it can be controlled by indirectly pushing the push rod 45 to move.

[0071] The indirect pushing method is as follows: Figure 15 20-21, The first squeezing plate 4 is provided with a long strip hole 49 that runs vertically through it. A movable sliding plate 50 is provided on the long strip hole 49. The lower end of the sliding plate 50 passes through the long strip hole 49 downward and abuts against the push rod 45 or the elastic section 46. The sliding plate 50 moves and causes the elastic section 46 to deform towards the deformation zone 47. The second mounting part 43 and the second fixing part 41 are released from positioning. Specifically, the middle part of the sliding plate 50 is installed on the elongated hole 49 by a spring clip, so that the sliding plate 50 can move horizontally in the elongated hole 49. The push rod 45 or the elastic section 46 is provided with a first guide part 51. The lower end of the sliding plate 50 is located above the first guide part 51 and abuts against the first guide part 51. The sliding plate 50 moves horizontally to contact the first guide part 51 at different positions. The elastic section 46 is subjected to force and deforms and bends towards the deformation zone 47 until the second mounting part 43 disengages from the second fixing part 41. The mounting plate 20 moves horizontally as a whole, and the first mounting part 42 disengages from the second fixing part 41. At this time, the mounting plate 20 separates from the first squeezing plate 4.

[0072] The method of directly pushing the push rod 45 is as follows: Figure 22 The first dewatering plate 4 has a long through hole 49. A push rod 45 is inserted into or passes upward through the long through hole 49. Applying force to the push rod 45 causes the elastic section 46 to deform towards the deformation zone 47, and the second mounting part 43 is released from its positioning with the second fixing part 41. Specifically, the second mounting part 43 has a second guide part 52. When a finger applies force to the upper end of the push rod 45 in a horizontal direction, the upper surfaces of the second mounting part 43 and the second fixing part 41 abut against each other. Under the guidance of the second guide part 52, the elastic section 46 gradually deforms and bends into the deformation zone 47 until the second mounting part 43 disengages from the second fixing part 41. The mounting plate 20 moves horizontally as a whole, and the first mounting part 42 disengages from the second fixing part 41. At this time, the mounting plate 20 separates from the first dewatering plate 4. Alternatively, the first mounting part 42 can be disassembled by first pressing the push rod 45 downward to deform the elastic section 46 towards the deformation area 47, causing the second mounting part 43 to detach from the second fixing part 41, and then pushing the push rod 45 horizontally to move the mounting plate 20 horizontally as a whole, thus disassembling the first mounting part 42 from the second fixing part 41. In this method, the elastic part can be deformed and bent even without the second guide part 52.

[0073] In the above embodiment, the cotton head 5 is provided with two mounting plates 20 at the positions corresponding to the two first squeezing plates 4. A quick-release mechanism 44 is provided between each first squeezing plate 4 and the corresponding mounting plate 20. There is a gap between the two mounting plates 20. The gap is located below the connecting plate 3. The cotton head 5 can be folded in half and squeezed out water at the position of the gap.

[0074] Preferably, the first mounting part 42 and the first fixing part 40 are inserted into each other, and the two are inserted along the length direction of the cotton head 5.

[0075] In this embodiment, the top of the push rod 45 or the sliding plate 50 protrudes from the top surface of the first squeezing plate 4. To prevent the squeezing frame 6 from pushing the push rod 45 or the sliding plate 50 when the first squeezing plate 4 rotates in conjunction with the squeezing frame 6, the depth of the first support part 11 or the second support part 14 extending into the squeezing port 9 is greater than the height of the push rod 45 or the sliding plate 50 protruding from the top of the first squeezing plate 4. Moreover, the first support part 11 and the second support part 14 are misaligned with the push rod 45 or the sliding plate 50. When the first support part 11 or the second support part 14 abuts against the first squeezing plate 4, the push rod 45 or the sliding plate 50 is in an elevated position and cannot contact the squeezing frame 6, thereby preventing the push rod 45 or the sliding plate 50 from accidentally moving during the folding and squeezing process, causing the cotton head 5 to fall off.

[0076] 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.
