At present, most of flat mops on the market are plate-shaped mop seats, the scrubbing area of the mop is increased, and the use is more convenient. In the prior art, the dewatering mode of the flat mop which is commonly used is hand-push extrusion type dewatering, and the dewatering mode is as follows: the invention discloses Chinese patent texts such as ZL200720192814.5, ZL201320019718.6, ZL201420624020.1 and the like, which comprise a mop rod and a flat mop plate movably connected to the mop rod, wherein a water squeezing mechanism is arranged on the mop rod, and water squeezing and cleaning of wiping materials on the flat mop plate are realized through relative squeezing movement between the water squeezing mechanism and the flat mop plate.

In the scheme described in the above prior patent document, when a user squeezes the flat mop, the flat mop plate needs to be broken to be parallel to the mop rod, that is, the flat mop head is in a cleaning and squeezing state; then a water squeezing mechanism is needed to position the flat mop plate, so that the flat mop plate is prevented from rotating; after the positioning is finished, the wringing mechanism is pushed and pulled to realize the relative squeezing movement between the wringing mechanism and the flat mop plate. This operation is often inconvenient and requires the user to operate the flat mop head during operation, which is very easy to touch the mop on the flat mop head, and is not hygienic. Under the background, a novel cleaning tool for a squeezing flat mop is described in the Chinese patent publication with the publication number of CN109394103A, and a positioning device can be used between a flat mop head and a mop rod in the scheme to keep the flat mop head in a cleaning and water squeezing state; when mopping, the flat mop head is separated from the control of the positioning device so as to rotate to the mopping state. Moreover, as shown in fig. 26 to 33, the positioning device includes an elastic top member disposed in the mop rod, the elastic top member includes a spring and a top block, and the top block is pushed against the movable connection between the flat mop head and the mop rod by the force of the spring during cleaning and squeezing water to position the flat mop head; when mopping, the mop rod or the flat mop head is pulled to rotate, so that the flat mop head is in a mopping state. For the flat mop with the positioning device, the applicant finds that the use process of the flat mop still has inconvenience, namely, the user still needs to press the flat mop to be parallel to the mop rod through external force to lock the flat mop, and therefore the user often manually breaks the flat mop plate when using the flat mop.

Example 1:

the flat mop shown in fig. 1-4 comprises a mop rod 1 and a mop head 2 connected to the lower end of the mop rod 1 through a rotating component. The rotating assembly comprises a hinged seat 3 connected to the mop head 2, the lower end part of the mop rod 1 is hinged to the hinged seat 3, the mop head 2 and the hinged seat 3 on the mop head can rotate relative to the mop rod 1 along the hinged axis a, and the axis direction of the hinged axis a is consistent with the width direction of the mop head 2. The end part of the mop rod 1 is provided with an elastic limiting component, and the output end of the elastic limiting component is in rolling fit with the contact surface of the hinge seat 3.

Specifically, in the embodiment shown in the figures, the lower end of the mop rod 1 is provided with a mounting groove 11. The elastic limiting assembly comprises a spring 41 and a limiting component 42 arranged at the end part of the spring 41, and the end part of the limiting component 42, which is far away from one side of the spring 41, is in rolling fit with the contact surface of the hinge seat 3. The stopper member 42 is positioned at the notch of the fitting groove 11, and the spring 41 is positioned in the fitting groove 11 in the stopper member 42. In the above-mentioned scheme, both the spring 41 and the limiting component 42 are installed in the assembling groove 11, and the assembling groove 11 restrains the limiting component 42 to prevent the limiting component 42 from being separated from the assembling groove 11 under the action of the spring 41. In a further preferred embodiment, the limiting member 42 is a ball, and the ball is in rolling fit with the contact surface of the hinge base 3.

Further, in the contact surface of the hinge base 3, the distance between the second arc-shaped section 32 and the hinge axis a is smaller than the minimum distance between the first arc-shaped section 31 and the hinge axis a, that is, the first arc-shaped section 31 is a gentle section, the second arc-shaped section 32 is an accelerating section, a gradient difference is generated between the first arc-shaped section 31 and the second arc-shaped section 32, when the output end of the elastic limit component enters the second arc-shaped section 32 from the first arc-shaped section 31, the relative movement between the two can be accelerated, so that the output end of the elastic limit component is faster close to the notch 33, and the effects of quick rebound and final positioning are generated. When needing to adjust mop head 2 to washing and crowded water state, the user only need lift up mop pole 1 and make mop head 2 unsettled, then shake dull and stereotyped the mop, as long as the output of the spacing subassembly of elasticity gets into second segmental arc 32 by first segmental arc 31, mop head 2 will kick-back and be parallel as to mop pole 1, wash promptly and crowded water state.
