Description

Stable water squeezing mop without pull handle

Technical Field

The present invention relates to a stable type mop without pull-handle, and more particularly to a mop structure without pull-handle, which can maintain the horizontal spreading of the wiping element by the pair of the connecting plates of the wiping element in a three-point contact manner.

Background

The mop is a cleaning tool necessary for home use, and how to wring the mop quickly and laborsavingly after use is a current trend for improving the mop, for example, taiwan patent No. M550111 discloses a laborsaving drainage mop, which comprises: the holding rod assembly comprises a holding tube and a supporting tube, wherein the holding tube is connected with the supporting tube; a water discharge assembly, which comprises a water absorption element and a squeezing device, wherein the squeezing device is used for squeezing the water of the water absorption element; and a force driving component which comprises a driving rod and a pair of connecting rods, when the driving rod is pushed downwards, the driving rod can drive the connecting rods to transmit mechanical energy, and the water absorbing element is pulled upwards, so that the water absorbing element is extruded by the extruding device to discharge water, and the aim of labor-saving water discharge is fulfilled.

However, the conventional labor-saving mop can achieve the purpose of saving labor as the length of the driving rod (pull handle) is longer, so that the length of the driving rod is usually about 40 cm, an operator must pull the long driving rod with a large radius to squeeze and drain water, and the use is very inconvenient due to the size of the user or the use environment.

In addition, in the mop of the prior art, when the water absorbing element is horizontally unfolded, because both sides of the water absorbing element are not stably supported, when mopping is carried out, as shown in fig. 1, both sides of the water absorbing element (M) are easy to generate upward tilting displacement (U) due to force, so that large pressure cannot be applied to the ground, dirt on the ground cannot be effectively removed, and the cleaning work is affected.
