Description

Technical Field

[0001] The invention relates to a method and device for cleaning and squeezing a squeezed common mop, belonging to the technical field of cleaning devices. Background Art

[0002] Mops are commonly used cleaning tools in people's lives, but it is very inconvenient to clean mops in a cleaning pool. They often need to be scrubbed and squeezed by hand to achieve a better cleaning and squeezing effect. Although there are some mops or mop cleaning buckets with cleaning or dehydration functions on the market, they can only use special mops and special cleaning and dehydration devices, which have complex structures, high manufacturing costs, and poor convenience and practicality. For example, "A cleaning bucket for hands-free mops" (State Intellectual Property Office of the People's Republic of China, invention patent application, application publication number CN110200561 A, application publication date 2019.09.06), and "A cleaning method for flat mops" (State Intellectual Property Office of the People's Republic of China, invention patent application, application publication number CN 110664366 A, application publication date 2020.01.10), can only use special mops and special cleaning and dehydration buckets.

[0004] To achieve the above object, the present invention provides the following technical solutions:

When the rocker is unfolded and moves to a position less than or equal to 180 degrees, the rocker swings to the limit position; a reset spring is arranged on the inner side of the rocker on the frame as a reset device to push the rocker 7 to swing, thereby driving the hinge angle of the two mutually movable hinged connecting rods at the central connecting rotation axis to unfold and move from a 0-degree angle position to a position less than or equal to 180 degrees; two rectangular screen-shaped water leakage extrusion plates are respectively fixedly connected to two opposite connecting rods at the top of two planar five-bar mechanisms, so that the two rectangular screen-shaped water leakage extrusion plates can rotate with each other at the central connecting rotation axis to form a movable hinge folding structure; when not cleaned, the two rectangular screens The hinge angle of the rectangular mesh-shaped water leakage squeezing plate is kept unfolded to the initial position less than or equal to 180 degrees under the action of the reset device; during cleaning, the external force acts on the folding structure of the central connecting rotating shaft of the movable hinge of the two rectangular mesh-shaped water leakage squeezing plates through the mop head cloth strip to change the hinge angle of the two rectangular mesh-shaped water leakage squeezing plates toward 0 degrees, that is, the two rectangular mesh-shaped water leakage squeezing plates fold and squeeze toward the mop head cloth strip at the same time, so as to realize the cleaning and squeezing of the mop head cloth strip. After cleaning and squeezing, the mop is taken out, and the hinge angle of the two folded rectangular mesh-shaped water leakage squeezing plates is unfolded and returned to the initial position less than or equal to 180 degrees under the action of the reset device.

The connecting rod mechanism is that the two planar five-bar connecting rods are equal and arranged symmetrically in parallel with each other; the planes of the two planar five-bar connecting rods are perpendicular to the plane of the rigid rectangular frame formed by the frame and the fixed rod; the relative hinge kinematic pairs of the two planar five-bar connecting rods are connected as a whole by 5 rotating shafts of equal length, that is, the central hinge kinematic pairs on the two planar five-bar connecting rods are connected by 1 central connecting rotating shaft, the two outer hinge kinematic pairs on the two planar five-bar connecting rods are connected by 2 outer connecting rotating shafts, and the two lower end hinge kinematic pairs on the two planar five-bar connecting rods are connected by 2 lower end connecting rotating shafts; two rectangular screen-shaped water leakage extrusion plates are laid and fixed on the relative connecting rods of the two planar five-bar connecting rods, and the two rectangular screen-shaped water leakage extrusion plates are distributed on both sides of the central hinge kinematic pair.

[0011] In the aforementioned squeezing type ordinary mop cleaning and squeezing device, a return spring is correspondingly arranged on the inner side of the rocker on the frame to push the rocker to swing, thereby driving the hinge angle of the two connecting rods at the central connecting rotating shaft to move from a 0 degree angle position to a position less than or equal to 180 degrees; a limit block is correspondingly arranged on the outer side of the rocker on the frame to limit the extreme position of the rocker swing when the hinge angle of the two connecting rods at the central connecting rotating shaft moves to a position less than or equal to 180 degrees.

[0012] In the aforementioned squeezing type common mop cleaning and squeezing device, a reset steel plate with strong elasticity is arranged through two rectangular mesh-shaped leaking squeeze plates, and the reset steel plate crosses the two rectangular mesh-shaped leaking squeeze plates and the central hinge kinematic pair.

[0031] Embodiment 3, as attached Figure 1-6 As shown, the essence of the reset spring 11 or 24 is to drive the hinge angle of the two rectangular screen-like leaking extrusion plates 3 or 17 at the central hinge motion pair 2 or 16 to move from a position of 0 degree to a position less than or equal to 180 degrees. Therefore, on the basis of realizing the same principle as above, we can use a reset steel plate with strong elasticity to penetrate the two rectangular screen-like leaking extrusion plates 3 or 17, and the reset steel plate crosses the two rectangular screen-like leaking extrusion plates and the central hinge motion pair; that is, the reset steel plates can realize the function of the original reset spring, and their essences are the same.

[0032] When used specifically

[0033] The device is placed in a mop cleaning pool. When cleaning the mop 28, the user holds the mop rod and places the cloth strip or the rubber cotton strip on the mop head at the central hinge folding structure of the two rectangular mesh-shaped water leakage squeezing plates 17, and pushes the central hinge motion pair 16 downward. The outer hinge motion pairs 18 on both sides and the upper ends of the rockers 20 swing toward the direction of the central hinge motion pair 16 with the lower end hinge motion pairs 21 of the rockers 20 on both sides as the center of the circle, so that the two rectangular mesh-shaped water leakage squeezing plates 17 fold at the central hinge motion pair 16 and generate a horizontal squeezing force to squeeze out the sewage in the cloth strip or the rubber cotton strip on the mop head of the mop 28; then, the faucet is turned on to flush the mop head with clean water. The mop rod is lifted upward, and the spring force of the return spring 24 pushes the rocker 20 to swing, driving the hinge angle of the two rectangular screen-shaped water leakage squeezing plates 17 at the central hinge motion pair 16 to move from a position of 0 degree to a position less than or equal to 180 degrees. At this time, the limit block 25 limits the extreme position of the swing of the rocker 20. In this process, the cloth strip or the rubber cotton strip of the mop head can absorb clean water. This is repeated to clean the mop head cloth strip or the rubber cotton strip of the mop 28. When the mop head cloth strip or the rubber cotton strip of the mop 28 is to be squeezed dry, the faucet is turned off, and the mop rod is pressed downward to squeeze out the water in the mop head cloth strip or the rubber cotton strip.
