Description

Technical Field

[0001] The invention relates to a folded water squeezing type foam cotton mop, wherein the foam cotton can be a rubber cotton head, a sponge head or the like. Background Art

[0002] There are roughly three ways to squeeze water from foam mops on the market: the first is hand-pulling squeezing; the second is flipping the mop head to squeeze water as a whole; and the third is folding the mop in half to squeeze water.

[0003] For example, the Chinese utility model patent "A folding water squeezing mop" with patent number ZL201320468680.0 (publication number CN203379085U), the Chinese utility model patent "A folding collodion mop" with patent number ZL201621230208.3 (publication number CN206729843U), and the Chinese utility model patent "Folding water squeezing collodion mop" with patent number ZL201821938901.5 (publication number CN209611033U) all disclose a folding water squeezing mop, which includes a mop rod. , a folding mop head, a squeezing rack, and a driving structure for driving the folding mop head to enter or exit the squeezing rack. The existing folding squeezing racks are all U-shaped forks, with two squeezing arms spaced apart on the left and right. The folding mop head can enter or exit the squeezing port formed by the squeezing arms through the driving structure. When the folding mop head exits the squeezing port, the folding mop head is in an unfolded mopping state under the action of its own spring. When the folding mop head enters the squeezing port, the squeezing arm drives the folding plate part of the folding mop head to swing downward and fold in half, forming a fold to fold and squeeze water from the wipe at the bottom of the folding plate.

[0004] The existing folding squeezing mop has the following defects: 1. The structure of driving the squeezing frame to slide is complicated, generally using a wrench drive method, a threaded rod transmission method, or a gear transmission method. 2. The existing folding squeezing mop cannot achieve a good balance between the labor-saving squeezing operation and the squeezing effect. 3. The existing squeezing frame can only squeeze the wiped material in the folding direction of the folding mop head, and the squeezing effect is poor.

[0005] In summary, the existing folding water squeezing type collodion mop can be further improved. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a folding water squeezing foam mop with a simple and reasonable structure and good folding water squeezing effect in view of the above-mentioned existing technical status.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a folding water squeezing foam mop, comprising a mop rod, a folding mop head with foam, and a water squeezing frame, wherein the folding mop head is movably connected to the lower end of the mop rod; the folding mop head comprises a middle plate body and two folding plates, wherein the middle plate body is movably connected to the lower end of the mop rod, the two folding plates are respectively hinged on two opposite sides of the middle plate body, an elastic member is provided between the folding plate and the middle plate body to keep the folding plate in an unfolded position, and the foam is connected to the bottom surface of the folding plate; the characteristic is that: the water squeezing frame The squeezing frame is on the mop rod and can slide up and down. The squeezing frame has an annular squeezing cavity with an opening facing downward. Two squeezing rollers are arranged in the squeezing cavity to form rolling squeezing on the top surface of the folding plate. When the squeezing frame is in an upward position, the folding mop head is separated from the squeezing cavity and is in an unfolded mopping state. When the squeezing frame moves downward, the lower part of the squeezing frame first contacts the top surface of the folding plate, and the folding plate is first prompted to swing to pre-fold and squeeze water. After the folding mop head partially enters the squeezing cavity, it contacts the top surface of the folding plate through the squeezing rollers, and the folding plate is squeezed to further squeeze water.

[0008] As a further improvement, the first squeezing force arm between the lower part of the squeezing frame and the rotation axis of the folding plate is greater than the second squeezing force arm between the axis of the squeezing roller and the rotation axis of the folding plate. This arrangement can make it easier for the lower part of the squeezing frame to trigger the folding plate to swing, and the resistance to squeezing water in advance is small, making the operation easy. In addition, the second squeezing force arm between the squeezing roller and the rotation axis of the folding plate is small, which can better apply squeezing force to the folding plate and achieve a good squeezing effect.

[0009] In order to better squeeze the foam, further improvement is made, two auxiliary squeezing rollers are further provided in the squeezing chamber, and the auxiliary squeezing rollers are arranged at intervals in front and behind to squeeze the side of the foam that protrudes from the folding plate. After the folding mop head is folded in half, the foam will protrude from the folding plate, and the auxiliary squeezing rollers will squeeze this part of the foam to more fully squeeze out the water in the foam.

[0010] Preferably, the auxiliary squeezing roller is arranged below the squeezing roller. After the folding mop head completely enters the squeezing chamber, the squeezing roller is always in contact with the back of the folding plate, otherwise the folding mop head is not easy to be separated from the squeezing chamber downward. At this time, if the auxiliary squeezing roller is arranged above the squeezing roller, the foam located below the squeezing roller cannot be squeezed by the auxiliary squeezing roller, affecting the squeezing effect of the auxiliary squeezing roller.

[0011] As a further improvement, a mounting bracket is installed in the extrusion chamber, and the extrusion roller and the auxiliary extrusion roller are both arranged on the mounting bracket. In this way, each extrusion roller and the auxiliary extrusion roller can be installed on the mounting bracket in advance, and then the mounting bracket is added and assembled into the extrusion chamber, so as to realize modular assembly and facilitate assembly.

[0012] Since the squeezing roller and the auxiliary squeezing roller are at different upper and lower positions and have different functions, in order to prevent the squeezing roller and the auxiliary squeezing roller from being misplaced during installation, preferably, a rib-groove limiting structure is provided between the two opposite outer end faces of the above-mentioned mounting bracket and the two opposite inner walls of the extrusion cavity, and the groove in the rib-groove limiting structure is provided on one of the outer end face of the mounting bracket or the inner wall of the extrusion cavity, and the rib in the rib-groove limiting structure is provided on the other of the outer end face of the mounting bracket or the inner wall of the extrusion cavity. The rib-groove limiting structure has an installation indication function to avoid incorrect installation.

[0013] Preferably, the mounting bracket is provided with a plurality of elastic clamping feet, and the inner wall of the extrusion cavity is provided with clamping grooves matching the elastic clamping feet. The buckle method has the advantage of convenient installation.

[0014] As an improvement, a positioning structure is provided between the water squeezing rack and the mop rod, and the positioning structure can position the water squeezing rack in an upward position. After the positioning structure is released, the water squeezing rack can slide up and down along the mop rod. The positioning structure can position the water squeezing rack in an upper position, and it will not move down easily, and will not affect mopping. After the positioning is released, the water squeezing rack can be moved to squeeze water from the folding mop head.

[0015] Preferably, the positioning structure comprises a positioning block fixed on the mop rod and an elastic slot arranged in the water squeezing frame, the opening of the elastic slot is upward and the diameter of the elastic slot is small at the top and large at the bottom. When the water squeezing frame is forced to move upward, the positioning block is inserted into the large diameter part of the elastic slot via the small diameter part of the elastic slot to complete the positioning. When the water squeezing frame is forced to move downward, the positioning block is separated from the elastic slot via the small diameter part of the elastic slot to complete the unlocking. The positioning structure involves few parts, is easy to assemble, and the positioning is also easy to release.

[0016] As a further improvement, the inner wall of the water squeezing frame is further provided with a guide groove located above and connected to the elastic slot, and the positioning block can slide up and down along the guide groove to ensure that the water squeezing frame is not easily displaced during the sliding process, and the cooperation between the positioning block and the guide groove can prevent the water squeezing frame from rotating around the axis of the mop rod. This guide structure makes full use of the positioning block component, does not need to set up an additional guide block, and has a simple structure. Of course, other existing guide structures can also be used.

[0017] Compared with the prior art, the advantages of the present invention are as follows: the structure causes the folded mop head to enter the extrusion chamber after folding through the upward and downward sliding of the water squeezing frame relative to the mop rod to complete the water squeezing, and no additional driving structure is required, the structure is simpler and more reasonable, and the cost is low; the squeezing roller and the folding plate form rolling friction, which is conducive to the upward movement of the folded mop head in the extrusion chamber, and the water squeezing operation is labor-saving; in addition, the squeezing roller is convex to the port of the extrusion chamber, and when squeezing water, the lower part of the water squeezing frame causes the folding plate to swing to pre-fold and squeeze water, and after the folded mop head partially enters the extrusion chamber, it contacts the top surface of the folding plate through the squeezing roller, and the squeezing roller causes the folding plate to swing for further squeezing water, and the water squeezing effect is better.

[0028] The present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 10 Shown is a preferred embodiment of the present invention.

[0030] A folding water squeezing foam mop comprises a mop rod 1, a folding mop head 2 with foam 4, and a water squeezing frame 3. The foam can be rubber cotton, sponge or the like. The folding mop head 2 is movably connected to the lower end of the mop rod 1.

[0031] The folding mop head 2 comprises a middle plate 21 and two folding plates 22, wherein the middle plate 21 is movably connected to the lower end of the mop rod 1, and the two folding plates 22 are respectively hinged to opposite sides of the middle plate 21, and an elastic member 23 is provided between the folding plate 22 and the middle plate 21 to keep the folding plate 22 in an unfolded position, and the foam 4 is connected to the bottom surface of the folding plate 22. The arrangement of the middle plate 21 allows the deformation space of the middle position of the foam 4 to be large, and the resistance encountered when folding is small. In addition, the arrangement of the middle plate 21 allows the two folding plates 21 to be folded inward at a larger angle, and the folding and squeezing effect is better.

[0032] The water squeezing frame 3 is arranged on the mop rod 1 and can slide up and down. The water squeezing frame 3 has a ring-shaped squeezing chamber 31 with an opening facing downward. Two squeezing rollers 7 that can roll and squeeze the top surface of the folding plate 22 are arranged in the squeezing chamber 31; when the water squeezing frame 3 is in the upward position, the folding mop head 2 is separated from the squeezing chamber 31, and the folding mop head 2 is in an unfolded mopping state.

[0033] During the downward movement of the water squeezing rack 3, the lower portion X of the water squeezing rack 3 first contacts the top surface of the folding plate 22, prompting the folding plate 22 to swing and fold in advance to squeeze water. After the folding mop head 2 partially enters the squeezing chamber 31, it contacts the top surface of the folding plate 22 through the squeezing roller 7, squeezing the folding plate 22 to further squeeze water.

[0034] A first squeezing force arm L1 between the lower portion X of the squeezing frame 3 and the rotation axis of the folding plate 22 is greater than a second squeezing force arm L2 between the axis of the squeezing roller 7 and the rotation axis of the folding plate 22 .

[0035] Two auxiliary squeezing rollers 8 are also provided in the squeezing chamber 31 . The auxiliary squeezing rollers 8 are arranged opposite to each other at a front-rear interval to squeeze the side portion 41 of the folded foam 4 of the side protruding folding plate 22 . The auxiliary squeezing rollers 8 are arranged below the squeezing roller 7 .

[0036] A mounting bracket 9 is installed in the extrusion cavity 31, and the extrusion roller 7 and the auxiliary extrusion roller 8 are both arranged on the mounting bracket 9. The mounting bracket 9 is provided with a plurality of elastic clamping feet 91, and the inner wall of the extrusion cavity 31 is provided with a clamping groove 311 matching with the elastic clamping feet 91.

[0037] A rib-groove limiting structure is provided between the two opposite outer end surfaces of the mounting bracket 9 and the two opposite inner walls of the extrusion cavity 31 , wherein the groove 92 in the rib-groove limiting structure is provided on the outer end surface of the mounting bracket 9 , and the rib 32 in the rib-groove limiting structure is provided on the inner wall of the extrusion cavity 31 .

[0038] A positioning structure is provided between the water squeezing frame 3 and the mop rod 1 , and the positioning structure can position the water squeezing frame in an upward position. After the positioning structure is released, the water squeezing frame 3 can slide up and down along the mop rod 1 .

[0039] The positioning structure includes a positioning block 5 fixed on the mop rod 1 and an elastic card slot 6 arranged in the water squeezing frame 3. The cross section of the positioning block 5 is circular, the opening of the elastic card slot 6 faces upward, and the diameter of the elastic card slot 6 is small at the top and large at the bottom. When the water squeezing frame 3 is forced to move upward, the positioning block 5 is inserted into the large diameter part 62 of the elastic card slot 6 via the small diameter part 61 of the elastic card slot 6 to complete the positioning. When the water squeezing frame 3 is forced to move downward, the positioning block 5 is separated from the elastic card slot 6 via the small diameter part 61 of the elastic card slot 6 to complete the unlocking. A guide groove 33 located above and connected to the elastic card slot 6 is also provided on the inner wall of the water squeezing frame 3. The positioning block 5 can slide up and down along the guide groove. The cooperation between the positioning block 5 and the guide groove can prevent the water squeezing frame 3 from rotating around the axis of the mop rod 1.

[0040] In this embodiment, the up-down direction refers to the length direction along the mop rod 1 ; the left-right direction refers to the length direction of the foldable mop head 2 .

[0041] The working principle and process of this embodiment are as follows:

[0042] Water squeezing operation: hold the squeezing frame 3 with one hand and the mop rod 1 with the other hand, push the squeezing frame 3 downward relative to the mop rod 1, the positioning block 5 is released from the elastic card slot 6 via the small-diameter portion 61 of the elastic card slot 6 to complete unlocking, the lower part of the squeezing chamber 31 touches the top surface of the folding plate 22 to continue to move downward and drive the two folding plates 22 to fold in half, and the lower part X of the squeezing chamber 31 causes the folding plate 22 to swing to pre-fold and squeeze water, such as Figure 6 , 7 After the folded mop head 2 partially enters the extrusion chamber 31, it contacts the top surface of the folding plate 22 through the extrusion roller 7, causing the folding plate 22 to swing for further squeezing, such as Figure 8 , 9 At the same time, the auxiliary squeezing roller 8 squeezes the side portion 41 of the folded foam 4 of the side protruding folding plate 22 .

[0043] Mopping operation: hold the water squeezing frame 3 with one hand and the mop rod 1 with the other hand, pull up the water squeezing frame 3 to move it up to a high position relative to the mop rod 1, until the folded mop head 2 is completely separated from the water squeezing frame 3, and the positioning block 5 is inserted into the large-diameter portion 62 of the elastic slot 6 through the small-diameter portion 61 of the elastic slot 6 to complete the positioning. At this time, the water squeezing handle 31 is in a high position. Because the foam head 2 is completely separated from the squeezing cavity 31 when mopping the floor, and the foam head 2 is movably connected to the lower end of the mop rod 1, the foam head 2 can be deflected during mopping, and the operation is more comfortable and reasonable.

[0044] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention can be modified and varied by a person skilled in the art. For example, the following driving block can also be a way to drive the caliper seat to move forward and backward to achieve water squeezing. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
