Description

Technical Field

[0001] The present invention relates to a foamed cotton mop, and in particular to a foamed cotton mop with a guiding structure. Background Art

[0002] At present, the use of cotton swab mops on the market is continuously developing towards cleaning and convenience, especially in its water squeezing function, which has been continuously improved. For example, in the "Foamed Cotton Head Mop with Improved Water Squeezing Method" published on January 23, 2018, with the publication number CN107616764A, a foamed cotton head mop is disclosed, including a mop rod and a foamed cotton head. The foamed cotton head is movably connected to the lower end of the mop rod. The mop rod is provided with a squeezing device that can slide along the mop rod. The foamed cotton head can be rotated to a position where its length direction is basically parallel to the mop rod and aligned with the squeezing device. When squeezing water, the squeezing device slides up and down along the length direction of the foamed cotton head and squeezes the bottom surface of the foamed cotton head to achieve water squeezing. When mopping the floor, the foamed cotton head is completely separated from the squeezing device. The squeezing device includes a squeezing handle provided on the mop rod. The squeezing handle can slide up and down relative to the mop rod. The squeezing handle is connected to a squeezing head through a connecting rod. The squeezing head has a through hole for the foamed cotton head to pass through, and a squeezing member for squeezing the bottom surface of the foamed cotton head passing through the through hole is provided in the through hole. When squeezing water, the foamed cotton head is rotated to a position where its side surface is aligned with the through hole. The foamed cotton head enters and passes through the through hole, and the squeezing member squeezes the bottom surface of the foamed cotton head to achieve water squeezing. When mopping the floor, the foamed cotton head is completely separated from the through hole.

[0003] In the disclosed foamed cotton head mop, when squeezing and cleaning the foamed cotton head, only need to hold the squeezing handle and push and pull along the axial direction of the mop rod to complete the squeezing and cleaning of the foamed cotton head. When the mop is used up, the squeezing handle will be pushed to the lower end of the mop rod. At this time, the squeezing head is located at the lower end of the mop rod. When using it next time, it is necessary to pull the squeezing head back, that is, the squeezing head passes through the foamed cotton head and returns to the position where the mop rod is located. However, for the disclosed foamed cotton mop, when the squeezing head squeezes along the length direction of the foamed cotton head, the squeezing force of the squeezing member on the surface of the foamed cotton head is fixed. In terms of the existing structure, it is impossible to optimize its water squeezing effect to the maximum extent. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a foamed cotton mop with a guiding structure in which when the squeezing head moves along the length direction of the foamed cotton, the squeezing member has a driving force to further squeeze the foamed cotton head.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: A foamed cotton mop with a guiding structure, which includes a mop rod and a mop head movably connected to the lower end of the mop rod. The mop head includes a mounting seat movably connected to the mop rod and a foamed cotton head fixed on the mounting seat. The mop head can be rotated to a position where its length direction is substantially parallel to the mop rod. A water squeezing device is also installed on the mop rod. The water squeezing device includes a water squeezing head that can relatively slide up and down with respect to the mop rod. The water squeezing head has a through hole for the foamed cotton head to pass through, and a water squeezing component for squeezing the surface of the foamed cotton head passing through the through hole is provided inside the through hole. The feature is that: The guiding structure is located between the axial side of the mounting seat and the inner wall of the through hole. The guiding structure includes an upward guiding structure for guiding the water squeezing component on the water squeezing head to squeeze the surface of the foamed cotton head and move along the axial direction of the foamed cotton head for squeezing.

[0006] The forward sliding of the water squeezing head is defined as advancing, and the backward sliding is defined as retreating. An independent upward guiding structure is provided between the water squeezing head and the mounting seat. When the water squeezing head slides forward and / or backward, the water squeezing head guides the water squeezing component to squeeze the surface of the foamed cotton head through the upward guiding structure.

[0007] The beneficial effects of the present invention are as follows: Through the upward guiding structure, when the water squeezing head moves forward or backward, in at least one direction of movement, the water squeezing head will drive the water squeezing component to move in the direction of squeezing the surface of the foamed cotton head, thereby improving the water squeezing effect; or when the water squeezing head moves forward and backward, in both directions of movement, the water squeezing head can squeeze the foamed cotton head, improving the water squeezing effect. During the entire operation process, the user drives the forward or backward movement of the water squeezing head, thereby enabling the water squeezing component to actively squeeze the end of the foamed cotton head, and further improving the water squeezing effect. The operation is convenient and fast. The distance between the upward straight rail and the upward guiding rib is the distance by which the water squeezing head offsets upward. The larger the distance, the greater the relative translation distance of the water squeezing head, that is, the greater the water squeezing pressure on the water squeezing head. The inclination angle of the upward inclined rail determines the speed change rate when the water squeezing head offsets upward. Among them, the forward and / or backward sliding of the water squeezing head refers to the following three situations: upward guiding structures are provided in both the forward and backward sliding directions of the water squeezing head; an upward guiding structure is only provided in the forward sliding direction of the water squeezing head; or an upward guiding structure is only provided in the backward sliding direction of the water squeezing head.

[0008] Among them, the guiding structure further includes a downward guiding structure for guiding the water squeezing component on the water squeezer head to completely or partially disengage from the surface of the foam cotton head and move along the axial direction of the foam cotton head; an independent downward guiding structure is provided between the water squeezer head and the mounting seat. When the water squeezer head slides forward or backward, the water squeezer head guides the water squeezing component to squeeze the surface of the foam cotton head through the upward guiding structure. When the water squeezer head slides reversely, the water squeezer head guides the water squeezing component to completely or partially disengage from the surface of the foam cotton head through the downward guiding structure. The function of the downward guiding structure is that when the water squeezer head slides reversely, the water squeezer head will drive the water squeezing component to move in the direction of completely or partially disengaging from the surface of the foam cotton head, thereby increasing the return speed of the water squeezer head and reducing the resistance received by the water squeezer head, making the operation more labor-saving. During the entire operation process, the user can achieve the operation by pushing and pulling the water squeezing handle, which is convenient and fast, and the water squeezing effect is remarkable. The distance between the downward straight rail and the downward guiding rib is the distance by which the water squeezer head deflects downward. The larger the distance, the larger the relative translation distance of the water squeezer head, that is, the smaller the resistance received. The inclination angle of the downward inclined rail determines the speed change rate when the water squeezer head deflects downward.

[0009] The first implementation scheme is as follows: The upward guiding structure includes an upward guiding rib fixed to the side of the mounting seat and arranged along the axial direction of the mounting seat, and an upward guiding rail fixed to the inner wall of the through hole and on the same straight line as the upward guiding rib. The upward guiding rail includes an upward inclined rail inclined towards the forward direction and an upward straight rail connected to the rear end of the upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the water squeezer head slides along the forward direction, the surface of the upward inclined rail abuts against the rear end of the upward guiding rib and slides, so that the rear end of the upward guiding rib relatively slides to the position where the upward straight rail is located, and the upward straight rail thus closely adheres to and moves along the surface of the upward guiding rib;

[0010] The downward guiding structure includes a downward guiding rib fixed to the side of the mounting seat and arranged along the axial direction of the mounting seat, and a downward guiding rail fixed to the inner wall of the through hole and on the same straight line as the downward guiding rib. The downward guiding rail includes a downward inclined rail located behind the upward inclined rail and inclined towards the forward direction, and a downward straight rail connected to the front end of the downward inclined rail and arranged parallel to the axial direction of the mounting seat. When the water squeezer head slides along the backward direction, the surface of the downward inclined rail abuts against the front end of the downward guiding rib and slides, so that the front end of the downward guiding rib relatively slides to the position where the downward straight rail is located, and the downward straight rail thus closely adheres to and moves along the surface of the downward guiding rib.

[0011] The second embodiment is as follows: The upward guiding structure includes upward guiding ribs fixed to the side of the mounting base and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the inner wall of the through-hole and in the same straight line as the upward guiding ribs. The upward guiding rail includes an upward inclined rail inclined towards the backward direction, and an upward straight rail connected to the front end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the extrusion head slides along the backward direction, the surface of the upward inclined rail abuts against the front end of the upward guiding rib and slides, so that the front end of the upward guiding rib relatively slides to the position where the upward straight rail is located, and the upward straight rail thus closely adheres to and moves along the surface of the upward guiding rib;

[0012] The downward guiding structure includes downward guiding ribs fixed to the side of the mounting base and arranged along the axial direction of the mounting base, and a downward guiding rail fixed to the inner wall of the through-hole and in the same straight line as the downward guiding ribs. The downward guiding rail includes a downward inclined rail located in front of the upward inclined rail and inclined towards the backward direction, and a downward straight rail connected to the rear end of the downward inclined rail and arranged parallel to the axial direction of the mounting base. When the extrusion head slides along the forward direction, the surface of the downward inclined rail abuts against the rear end of the downward guiding rib and slides, so that the rear end of the downward guiding rib relatively slides to the position where the downward straight rail is located, and the downward straight rail thus closely adheres to and moves along the surface of the downward guiding rib.

[0013] The third implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed to the inner wall of the through-hole and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the side of the mounting base and in the same straight line as the upward guiding rail. The upward guiding rail includes an upward inclined rail inclined towards the forward direction, and an upward straight rail connected to the front end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the extrusion head slides along the forward direction, the front end of the upward guiding rib abuts against the surface of the upward inclined rail and slides to the position where the upward straight rail is located, and moves along the surface of the upward straight rail towards the forward direction;

[0014] The downward guiding structure includes downward guiding ribs fixed to the inner wall of the through-hole and arranged along the axial direction of the mounting base, and a downward guiding rail fixed to the side of the mounting base and in the same straight line as the downward guiding ribs. The downward guiding rail includes a downward inclined rail located in front of the upward inclined rail and inclined towards the forward direction, and a downward straight rail connected to the rear end of the downward inclined rail and arranged parallel to the axial direction of the mounting base. When the extrusion head slides along the forward direction, the rear end of the downward guiding rib abuts against the surface of the downward inclined rail and slides to the position where the downward straight rail is located, and moves along the surface of the downward straight rail towards the backward direction.

[0015] The fourth implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed at the inner wall of the through hole and arranged along the axial direction of the mounting seat, and an upward guiding rail fixed at the side of the mounting seat and located on the same straight line as the upward guiding rail. The upward guiding rail includes an upward inclined rail inclined towards the backward direction, and an upward straight rail connected to the rear end of the upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides along the backward direction, the rear end of the upward guiding rib abuts against the surface of the upward inclined rail and slides to the position where the upward straight rail is located, and then moves along the surface of the upward straight rail towards the backward direction;

[0016] The downward guiding structure includes downward guiding ribs fixed at the inner wall of the through hole and arranged along the axial direction of the mounting seat, and a downward guiding rail fixed at the side of the mounting seat and located on the same straight line as the downward guiding rib. The downward guiding rail includes a downward inclined rail located behind the upward inclined rail and inclined towards the backward direction, and a downward straight rail connected to the front end of the downward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides along the forward direction, the front end of the downward guiding rib abuts against the surface of the downward inclined rail and slides to the position where the downward straight rail is located, and then moves along the surface of the downward straight rail towards the forward direction.

[0017] An upper stop edge is also provided at an adjacent position of the upward straight rail, which is spaced from the upward straight rail and is used to limit the upward guiding rib to slide against the upward straight rail; A lower stop edge is also provided at an adjacent position of the downward straight rail, which is spaced from the downward straight rail and is used to limit the downward guiding rib to slide against the downward straight rail. Through the limiting action of the upper stop edge and the lower stop edge, when the upward straight rail slides against the upward guiding rib, the fit between them is closer, thereby ensuring more stable operation.

[0018] The fifth implementation scheme is as follows: The upward guiding structure includes a first upward guiding structure and a second upward guiding structure. The first upward guiding structure includes first upward guiding ribs fixed at the side of the mounting seat and arranged along the axial direction of the mounting seat, and a first upward guiding rail fixed at the inner wall of the through hole and located on the same straight line as the first upward guiding ribs. The first upward guiding rail includes a first upward inclined rail inclined towards the forward direction, and a first upward straight rail connected to the rear end of the first upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides along the forward direction, the surface of the first upward inclined rail abuts against the rear end of the first upward guiding rib and slides, so that the rear end of the first upward guiding rib relatively slides to the position where the first upward straight rail is located, and then the first upward straight rail closely adheres to and moves along the surface of the first upward guiding rib;

[0019] The second upward guiding structure includes a second upward guiding rib fixed to the side of the mounting seat and arranged along the axial direction of the mounting seat, and a second upward guiding rail fixed to the inner wall of the through hole and on the same straight line as the second upward guiding rib. The second upward guiding rail includes a second upward inclined rail located behind the first upward inclined rail and inclined in the backward direction, and a second upward straight rail connected to the front end of the second upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides in the backward direction, the surface of the second upward inclined rail abuts against the front end of the second upward guiding rib and slides, so that the front end of the second upward guiding rib relatively slides to the position where the second upward straight rail is located, and the second upward straight rail thus closely adheres to and moves along the surface of the second upward guiding rib.

[0020] The sixth implementation scheme is as follows: The upward guiding structure includes a first upward guiding structure and a second upward guiding structure. The first upward guiding structure includes a first upward guiding rib fixed to the inner wall of the through hole and arranged along the axial direction of the mounting seat, and a first upward guiding rail fixed to the side of the mounting seat and on the same straight line as the first upward guiding rail. The first upward guiding rail includes a first upward inclined rail inclined in the forward direction, and a first upward straight rail connected to the front end of the first upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides in the forward direction, the front end of the first upward guiding rib abuts against the surface of the first upward inclined rail and slides to the position where the first upward straight rail is located, and moves along the surface of the first upward straight rail in the forward direction;

[0021] The second upward guiding structure includes a second upward guiding rib fixed to the inner wall of the through hole and arranged along the axial direction of the mounting seat, and a second upward guiding rail fixed to the side of the mounting seat and on the same straight line as the second upward guiding rail. The second upward guiding rail includes a second upward inclined rail inclined in the backward direction, and a second upward straight rail connected to the rear end of the second upward inclined rail and arranged parallel to the axial direction of the mounting seat. When the extrusion head slides in the backward direction, the rear end of the second upward guiding rib abuts against the surface of the second upward inclined rail and slides to the position where the second upward straight rail is located, and moves along the surface of the second upward straight rail in the backward direction.

[0022] At an adjacent position of the first upward straight rail, there is also a first upper stop edge arranged at an interval from the first upward straight rail and used to limit the first upward guiding rib from sliding while abutting against the first upward straight rail; at an adjacent position of the second upward straight rail, there is also a second upper stop edge arranged at an interval from the second upward straight rail and used to limit the second upward guiding rib from sliding while abutting against the second upward straight rail.

[0023] The seventh implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed to the side of the mounting base and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the inner wall of the through-hole and on the same straight line as the upward guiding ribs. The upward guiding rail includes an upward inclined rail inclined towards the forward direction, and an upward straight rail connected to the rear end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the water squeezing head slides along the forward direction, the surface of the upward inclined rail abuts against the rear end of the upward guiding rib and slides, so that the rear end of the upward guiding rib relatively slides to the position where the upward straight rail is located, and the upward straight rail thus closely adheres to and moves along the surface of the upward guiding rib. In this scheme, when the water squeezing head slides in a certain direction, there is only the upward guiding structure, and when sliding in the reverse direction, the downward guiding structure can be set or not. It should be specifically pointed out that if the downward guiding structure is set, in addition to the specific schemes disclosed above, the surface of the foam head can also be used as the downward guiding structure. When the water squeezing head slides in the reverse direction, the water squeezing component on the water squeezing head presses against the surface of the foam head. Due to the reverse force, that is, the surface of the foam head pushes against the water squeezing component, so that the water squeezing component is in a state of partially detaching from the surface of the foam head, and it also avoids the interference of the upward guiding structure when the water squeezing head slides in the reverse direction.

[0024] The eighth implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed to the side of the mounting base and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the inner wall of the through-hole and on the same straight line as the upward guiding ribs. The upward guiding rail includes an upward inclined rail inclined towards the backward direction, and an upward straight rail connected to the front end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the water squeezing head slides along the backward direction, the surface of the upward inclined rail abuts against the front end of the upward guiding rib and slides, so that the front end of the upward guiding rib relatively slides to the position where the upward straight rail is located, and the upward straight rail thus closely adheres to and moves along the surface of the upward guiding rib. For the possible schemes when the water squeezing head slides in the reverse direction, refer to the description of the seventh implementation scheme.

[0025] The ninth implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed to the inner wall of the through-hole and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the side of the mounting base and on the same straight line as the upward guiding rail. The upward guiding rail includes an upward inclined rail inclined towards the forward direction, and an upward straight rail connected to the front end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the water squeezing head slides along the forward direction, the front end of the upward guiding rib abuts against the surface of the upward inclined rail and slides to the position where the upward straight rail is located, and moves along the surface of the upward straight rail towards the forward direction. For the possible schemes when the water squeezing head slides in the reverse direction, refer to the description of the seventh implementation scheme.

[0026] The tenth implementation scheme is as follows: The upward guiding structure includes upward guiding ribs fixed to the inner wall of the through hole and arranged along the axial direction of the mounting base, and an upward guiding rail fixed to the side of the mounting base and located on the same straight line as the upward guiding rail. The upward guiding rail includes an upward inclined rail inclined towards the backward direction, and an upward straight rail connected to the rear end of the upward inclined rail and arranged parallel to the axial direction of the mounting base. When the water squeezing head slides along the backward direction, the rear end of the upward guiding rib abuts against the surface of the upward inclined rail and slides to the position where the upward straight rail is located, and then moves along the surface of the upward straight rail towards the backward direction. For the possible scheme when the water squeezing head slides reversely, refer to the description of the seventh implementation scheme.

[0027] The water squeezing device further includes a water squeezing handle arranged on the mop rod. The water squeezing handle can slide relatively up and down with respect to the mop rod. The water squeezing handle is connected to the water squeezing head through a connecting rod; the connecting rod is made of a flexible material. The flexible material refers to an elastic material. After the elastic material deforms, if the applied deformation force is removed, it can automatically return to its original state. In this embodiment, the connecting rod can be made of an elastic metal rod, a plastic rod, or the like. Brief Description of the Drawings

[0044] The present invention will be further described below with reference to the accompanying drawings:

[0045] Taking Figure 2 the foam cotton mop as a standard, the foam cotton mop is placed horizontally (i.e., the axis is horizontal), the front refers to the left end of the mop rod 11 (i.e., the end where the mop head 12 is located), the rear refers to the right end of the mop rod 11, the forward movement of the water squeezing head 23 from back to front is forward, and the backward movement from front to back is backward. The upward movement refers to the upward offset of the water squeezing head 23. When the water squeezing head 23 moves upward, the water squeezing component 231 on the water squeezing head 23 is equivalent to moving towards the surface of the foam cotton head 122, that is, the water squeezing component 231 squeezes the foam cotton head 122; the downward movement refers to the downward offset of the water squeezing head 23. When the water squeezing head 23 moves downward, the water squeezing component 231 on the water squeezing head 23 is equivalent to moving away from the surface of the foam cotton head 122, that is, the water squeezing component 231 disengages from the extrusion of the foam cotton head 122.

[0046] Such as Figures 1 - 4As shown in the figure, this embodiment includes a mop rod 11 and a mop head 12 movably connected to the lower end of the mop rod 11. The mop head 12 includes a mounting base 121 movably connected to the mop rod 11 and a foamed cotton head 122 fixed on the mounting base 121. The mop head 12 can be rotated to a position where its length direction is substantially parallel to the mop rod 11. A water squeezing device 2 is also installed on the mop rod 11. The water squeezing device 2 includes a water squeezing handle 21 provided on the mop rod 11. The water squeezing handle 21 can slide relative to the mop rod 11 back and forth. The water squeezing handle 21 is connected to a water squeezing head 23 through a connecting rod 22. The water squeezing head 23 has a through hole 232 for the foamed cotton head 122 to pass through, and a water squeezing component 231 for squeezing the surface of the foamed cotton head 122 passing through the through hole 232 is provided in the through hole 232. Among them, the connecting rod 22 is made of a flexible material, and this flexible material can be made of an elastic metal rod, a plastic rod or other materials. The flexible strength here can be selected according to the actual effect, as long as it can ensure that when the water squeezing head 23 moves forward or backward and the water squeezing head 23 deflects upward or downward, the connecting rod 22 can still work stably. A guiding structure is provided between the axial side of the mounting base 121 and the inner wall of the through hole 232. The guiding structure includes an upward guiding structure 31a for guiding the water squeezing component 231 on the water squeezing head 23 to squeeze the surface of the foamed cotton head 122 and move axially along the foamed cotton head 122, and a downward guiding structure 32a for guiding the water squeezing component 231 on the water squeezing head 23 to disengage from the surface of the foamed cotton head 122 and move axially along the foamed cotton head 122. Among them, the water squeezing component 231 is a water squeezing roller, and the water squeezing roller is hinged in the through hole 232 of the water squeezing head 23. When the foamed cotton head 122 passes through the through hole, the roller surface of the water squeezing roller will squeeze the bottom surface of the foamed cotton head 122, so as to achieve the water squeezing effect.

[0047] In this embodiment, the upward guiding structure 31a includes an upward guiding rib 311a fixed to the side of the mounting base 121 and arranged along the axial direction of the mounting base 121, and an upward guiding rail fixed to the inner wall of the through hole 232 and on the same straight line as the upward guiding rib 311a. The upward guiding rail includes an upward inclined rail 312a inclined towards the forward direction, and an upward straight rail 313a connected to the rear end of the upward inclined rail 312a and arranged parallel to the axial direction of the mounting base 121. When the extrusion head 23 slides in the forward direction, the surface of the upward inclined rail 312a abuts against the rear end of the upward guiding rib 311a and slides, so that the rear end of the upward guiding rib 311a relatively slides to the position where the upward straight rail 313a is located, and then the upward straight rail 313a closely adheres to and moves along the surface of the upward guiding rib 311a. The downward guiding structure 32a includes a downward guiding rib 321a fixed to the side of the mounting base 121 and arranged along the axial direction of the mounting base 121, and a downward guiding rail fixed to the inner wall of the through hole 232 and on the same straight line as the downward guiding rib 321a. The downward guiding rail includes a downward inclined rail 322a located behind the upward inclined rail 312a and inclined towards the forward direction, and a downward straight rail 323a connected to the front end of the downward inclined rail 322a and arranged parallel to the axial direction of the mounting base 121. When the extrusion head 23 slides in the backward direction, the surface of the downward inclined rail 322a abuts against the front end of the downward guiding rib 321a and slides, so that the front end of the downward guiding rib 321a relatively slides to the position where the downward straight rail 323a is located, and then the downward straight rail 323a closely adheres to and moves along the surface of the downward guiding rib 321a.

[0048] At an adjacent position to the upward straight rail 313a, there is an upper stop edge 711 which is arranged at an interval from the upward straight rail 313a and is used to limit the sliding of the upward guiding rib 311a against the upward straight rail 313a; at an adjacent position to the downward straight rail 323a, there is a lower stop edge 712 which is arranged at an interval from the downward straight rail 323a and is used to limit the sliding of the downward guiding rib 321a against the downward straight rail 323a. Through the limiting action of the upper stop edge 711 and the lower stop edge 712, when the upward straight rail 313a slides against the upward guiding rib 311a, they fit more closely to each other, thus ensuring more stable operation.

[0049] The distance between the upward straight rail 313a and the upward guiding rib 311a is the distance by which the extrusion head 23 offsets upward; similarly, the distance by which the extrusion head 23 offsets downward is the distance between the downward straight rail 323a and the downward guiding rib 321a. The inclination angle of the upward inclined rail 312a determines the speed change rate when the extrusion head 23 offsets upward; similarly, the inclination angle of the downward inclined rail 322a determines the speed change rate when the extrusion head 23 offsets downward.

[0050] In this embodiment, the upward guiding structure 31a and the downward guiding structure 32a can be arranged on a guiding block 9A. The surface of the guiding block 9A is respectively provided with an upward inclined surface, an upward straight rail, a downward inclined surface and a downward straight rail as required. Refer to the attached drawings, which are parallelograms. Of course, the present application is not limited to the structure shown in the drawings, and can also be extended to other asymmetric structures. In addition, the upward guiding rib 311a and the downward guiding rib 321a can also be convex columns or convex blocks with a circular, rectangular or other cross-sectional shapes, not limited to long strips. And when the guiding rib is in a non-long strip form, the lengths of the upward straight rail 313a and the downward straight rail 323a should be correspondingly lengthened, so as to ensure that when the water squeezing head 23 slides back and forth along the foam head, there is a stable limiting fit between them, and at the same time ensure the normal functioning of the water squeezing function. In addition, the upward guiding rib 311a and the downward guiding rib 321a can adopt the same guiding rib. The upper edge surface of the guiding rib serves as the limiting function of the upward guiding rib 311a and is used to cooperate with the upward straight rail 313a; the lower edge surface of the guiding rib serves as the limiting function of the downward guiding rib 321a and is used to cooperate with the downward straight rail 323a. The working principles and naming of the guiding block and the guiding rib in other embodiments are the same, so they will not be elaborated in the subsequent embodiments.

When the extrusion head 23 slides in the backward direction, the surface of the upward inclined rail 312b abuts against the front end of the upward guiding rib 311b and slides, so that the front end of the upward guiding rib 311b relatively slides to the position where the upward straight rail 313b is located, and the upward straight rail 313b thus closely adheres to and moves along the surface of the upward guiding rib 311b. The downward guiding structure 32b includes a downward guiding rib 321b fixed to the side of the mounting seat 121 and arranged along the axial direction of the mounting seat 121, and a downward guiding rail fixed to the inner wall of the through-hole 232 and in the same straight line as the downward guiding rib 321b.

The downward guiding structure 42a includes downward guiding ribs 421a fixed to the inner wall of the through-hole and arranged along the axial direction of the mounting base 121, and a downward guiding rail fixed to the side of the mounting base 121 and on the same straight line as the downward guiding ribs 421a. The downward guiding rail includes a downward inclined rail 422a located in front of the upward inclined rail 412a and inclined towards the forward direction, and a downward straight rail 423a connected to the rear end of the downward inclined rail 422a and arranged parallel to the axial direction of the mounting base 121. When the extrusion head 23 slides in the forward direction, the rear end of the downward guiding rib 421a abuts against the surface of the downward inclined rail 422a and slides to the position where the downward straight rail 423a is located, and then moves along the surface of the downward straight rail 423a towards the backward direction.

[0053] Similarly, in this embodiment, the upward guiding structure 41a and the downward guiding structure 42a can be arranged on a guiding block 9B. The surface of the guiding block 9B is respectively provided with an upward inclined surface, an upward straight rail, a downward inclined surface and a downward straight rail as required. Refer to the attached drawing, which is a parallelogram. Of course, what the present application intends to protect is not limited to the structure shown in the figure, and can also be extended to other asymmetric structures.

[0054] Embodiment 4: As Figure 8As shown, the difference from the first embodiment lies mainly in the guiding structure. The upward guiding structure 41b includes upward guiding ribs 411b fixed to the inner wall of the through-hole 232 and arranged along the axial direction of the mounting base 121, and an upward guiding rail fixed to the side of the mounting base 121 and on the same straight line as the upward guiding ribs 411b. The upward guiding rail includes an upward inclined rail 412b inclined toward the backward direction, and an upward straight rail 413b connected to the rear end of the upward inclined rail 412b and arranged parallel to the axial direction of the mounting base 121. When the extrusion head 23 slides in the backward direction, the rear end of the upward guiding rib 411b abuts against the surface of the upward inclined rail 412b and slides to the position where the upward straight rail 413b is located, and then moves along the surface of the upward straight rail 413b in the backward direction.

When the extrusion head 23 slides in the forward direction, the front end of the downward guiding rib 421b abuts against the surface of the downward inclined rail 422b and slides to the position where the downward straight rail 423b is located, and then moves along the surface of the downward straight rail 423b in the forward direction.

[0055] Embodiment Five: As Figure 9 shown, the difference from the first embodiment lies mainly in the guiding structure. In this embodiment, the guiding structure only includes an upward guiding structure for guiding the extrusion member 231 on the extrusion head 23 to extrude the surface of the foaming cotton head 122 and move axially along the foaming cotton head 122 for extrusion.

[0056] The upward guiding structure includes a first upward guiding structure 51 and a second upward guiding structure 52. The first upward guiding structure 51 includes a first upward guiding rib 511 fixed to the side of the mounting seat 121 and arranged along the axial direction of the mounting seat 121, and a first upward guiding rail fixed to the inner wall of the through-hole and on the same straight line as the first upward guiding rib 511. The first upward guiding rail includes a first upward inclined rail 512 inclined towards the forward direction and a first upward straight rail 513 connected to the rear end of the first upward inclined rail 512 and arranged parallel to the axial direction of the mounting seat 121. When the extrusion head 23 slides along the forward direction, the surface of the first upward inclined rail 512 abuts against the rear end of the first upward guiding rib 511 and slides, so that the rear end of the first upward guiding rib 511 relatively slides to the position where the first upward straight rail 513 is located, and the first upward straight rail 513 thus closely adheres to and moves along the surface of the first upward guiding rib 511. The second upward guiding structure 52 includes a second upward guiding rib 521 fixed to the side of the mounting seat 121 and arranged along the axial direction of the mounting seat 121, and a second upward guiding rail fixed to the inner wall of the through-hole 232 and on the same straight line as the second upward guiding rib 521. The second upward guiding rail includes a second upward inclined rail 522 located behind the first upward inclined rail 512 and inclined towards the backward direction, and a second upward straight rail 523 connected to the front end of the second upward inclined rail 522 and arranged parallel to the axial direction of the mounting seat 121. When the extrusion head 23 slides along the backward direction, the surface of the second upward inclined rail 522 abuts against the front end of the second upward guiding rib 521 and slides, so that the front end of the second upward guiding rib 521 relatively slides to the position where the second upward straight rail 523 is located, and the second upward straight rail 523 thus closely adheres to and moves along the surface of the second upward guiding rib 521. Among them, the first upward straight rail 513 and the second upward straight rail 523 are the same side in this embodiment.

[0057] At an adjacent position of the first upward straight rail 513, there is also a first upper stop edge 721 which is arranged at an interval from the first upward straight rail 513 and is used to limit the first upward guiding rib 511 from sliding while abutting against the first upward straight rail 513; at an adjacent position of the second upward straight rail 523, there is also a second upper stop edge 722 which is arranged at an interval from the second upward straight rail 523 and is used to limit the second upward guiding rib 521 from sliding while abutting against the second upward straight rail 523. Among them, in this embodiment, the first upper stop edge 721 and the second upper stop edge 722 are the same stop edge, which is marked as 721(722) in the drawings.

[0058] Embodiment Six: As Figure 10As shown, the difference from the fifth embodiment mainly lies in the upper guiding structure. The upward guiding structure includes a first upward guiding structure 61 and a second upward guiding structure 62. The first upward guiding structure includes a first upward guiding rib 611 fixed to the inner wall of the through hole 232 and arranged along the axial direction of the mounting base 121, and a first upward guiding rail fixed to the side of the mounting base 121 and located on the same straight line as the first upward guiding rib 611. The first upward guiding rail includes a first upward inclined rail 612 inclined towards the forward direction, and a first upward straight rail 613 connected to the front end of the first upward inclined rail 612 and arranged parallel to the axial direction of the mounting base 121. When the water squeezing head 22 slides in the forward direction, the front end of the first upward guiding rib 611 abuts against the surface of the first upward inclined rail 612 and slides to the position where the first upward straight rail 613 is located, and then moves along the surface of the first upward straight rail 613 in the forward direction. The second upward guiding structure 62 includes a second upward guiding rib 621 fixed to the inner wall of the through hole and arranged along the axial direction of the mounting base 121, and a second upward guiding rail fixed to the side of the mounting base 121 and located on the same straight line as the second upward guiding rib 621. The second upward guiding rail includes a second upward inclined rail 622 inclined towards the backward direction, and a second upward straight rail 623 connected to the rear end of the second upward inclined rail 622 and arranged parallel to the axial direction of the mounting base 121. When the water squeezing head 23 slides in the backward direction, the rear end of the second upward guiding rib 621 abuts against the surface of the second upward inclined rail 622 and slides to the position where the second upward straight rail 623 is located, and then moves along the surface of the second upward straight rail 623 in the backward direction.

[0059] In each of the above embodiments, the water squeezing member 231 is not limited to the water squeezing roller structure disclosed in the first embodiment, such as Figure 11As shown, the water squeezing component 231 can also be replaced by water squeezing bumps. In addition, the water squeezing component 231 can also adopt a second type of solution, that is, the water squeezing bumps are movably connected to the through hole by springs, and the water squeezing bumps move towards the direction where the foam cotton head 122 is located via the springs, so as to increase the squeezing force of the water squeezing bumps and improve the water squeezing effect. The water squeezing component 231 can also adopt a third type of solution. Positioning columns 411 are respectively protruded from the axial two ends of the water squeezing bumps, and inclined rails 412 which are inclined gradually upward towards the center of the through hole and for each positioning column 411 to be correspondingly received are arranged on the inner surface of the through hole. Due to the limitation of the inclined rails 412, the water squeezing bumps are clamped in the inclined rails 412 through the positioning columns 411 at the shaft ends, and it is ensured that the water squeezing bumps slide along the inclined direction of the inclined rails 412. Since the two inclined rails 412 are inclined gradually upward towards the center of the through hole, which is similar to forming an "eight" character structure, during the upward movement of the foam cotton head 122, the water squeezing bumps slide upward and inward, making the opening of the through hole 233 gradually become smaller; during the downward movement of the foam cotton head 122, the water squeezing bumps slide downward and outward, making the through hole 233 in the normal opening size, and the surface of the foam cotton head 122 is fully squeezed when squeezing water. Here, the water squeezing bumps can be replaced by water squeezing rollers.

[0060] As Figure 12 shown, the water squeezing component 231 can also adopt a fourth type of solution, that is, the water squeezing component 231 is a pair of symmetrically arranged water squeezing rollers, and the symmetric water squeezing rollers are used to squeeze the two axial side surfaces of the foam cotton head 122 passing through the through hole. The water squeezing bumps or water squeezing rollers can be fixedly installed at the through hole. Here, the water squeezing rollers can be replaced by water squeezing bumps. The water squeezing component 231 can also adopt a fifth solution, that is, the water squeezing bumps can be movably installed in the through hole by springs to elastically squeeze the two axial side surfaces of the foam cotton head passing through the through hole. The water squeezing component 231 can also adopt a sixth type of solution, that is, the water squeezing bumps or water squeezing rollers can also be movably installed in the through hole by the inclined guide rails arranged on the inner wall of the through hole. Among them, the two axial side surfaces of the foam cotton head 122 refer to the left surface of the foam cotton head 122 and the right surface of the foam cotton head 122 when the observer is facing the bottom surface of the foam cotton head 122 with the length direction of the foam cotton head as the axis.

[0061] Embodiment Seven: As Figure 13 shown, the main difference from Embodiment One is that it only includes an upward guiding structure 31a. In this embodiment, the downward guiding structure is not drawn, at least the downward guiding structure disclosed in Embodiment One is not adopted.

[0062] For this embodiment, from the perspective of use, there are the following situations, and it can be considered that this situation belongs to the downward guiding structure, that is, when the water squeezing component 231 abuts against the bottom surface of the foam cotton head 122, the bottom surface of the foam cotton head 122 functions as the downward guiding rib 321a.

[0063] When the water squeezing head 23 slides reversely, the water squeezing component 231 on the water squeezing head 23 presses against the surface of the foam cotton head 122. Due to the reverse acting force, that is, the surface of the foam cotton head 122 pushes against the water squeezing component 231, making the water squeezing component 231 in a state of being partially separated from the surface of the foam cotton head 122, and also avoiding the interference of the upward guiding structure 31a when the water squeezing head 23 slides reversely.

[0064] Embodiment VIII: As Figure 14 shown, the main difference from Embodiment II is that it only includes the upward guiding structure 31b. Regarding whether there is a downward guiding structure, reference can be made to the description of Embodiment VII.

[0065] Embodiment IX: As Figure 15 shown, the main difference from Embodiment III is that it only includes the upward guiding structure 41a. Regarding whether there is a downward guiding structure, reference can be made to the description of Embodiment VII.

[0066] Embodiment X: As Figure 16 shown, the main difference from Embodiment IV is that it only includes the upward guiding structure 41b. Regarding whether there is a downward guiding structure, reference can be made to the description of Embodiment VII.

[0067] In the above embodiments, regarding the relative movement mode between the water squeezing head 23 and the foam cotton head 122, the foam cotton head 122 is relatively stationary, and the water squeezing head 23 moves axially along the mop rod 11, so as to realize the water squeezing of the water squeezing head 23 on the foam cotton head 122. In addition, there is another existing structure, where the water squeezing head 23 is relatively stationary, and the foam cotton head 122 is driven by a driving structure to move axially along the mop rod 11, so that the foam cotton head 122 passes through the through hole 232 on the water squeezing head 23, thereby achieving the purpose of water squeezing.

[0068] In each of the embodiments, the orientation or positional relationship indicated by "front", "rear", "left", "right", "up", "down", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention or simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or a connection through an intermediate medium, and it can be the communication inside two components.
