A kind of mophead and mop

Technical field

The invention belongs to the daily life technical field, relate to a kind of cleaning appliance commonly used, especially relevant with mop.

Background technology

Mop has very high utilization rate in people's life as the daily cleaning instrument.In various mops, the round end mop occurs the earliest, and, because of characteristics such as it are simple and easy to use, cheap, cleaning effect is good, extremely people like.Tradition round end mop is by tying up many cloths at mop rod one end or many cotton cords are made, in order to improve the utilization rate of mop rod, also have cloth or cotton cord are banded on a shorter plug and make mophead, then adopt dismountable mode to be linked and packed into mop plug and mop rod.The disadvantage of tradition round end mop is that cloth or cotton cord are not easy to tie up firmly, and cloth or cotton cord easily trackslip or slippage on mop rod or plug, and then cause the lost of life of mop.Its reason, on the one hand, although, in the process of tying up cloth or cotton cord, can draw very tightly by the bundle rope, while in the end giving the knotting of bundle rope, under the tensioner effect of cloth or cotton cord, the bundle rope can inevitably loosen.On the other hand, mop in use, as mop floor or during water wring, cloth or cotton cord on it (especially outer cloth or cotton cord) easily are subject to downwards (for convenience of describing, this paper will be defined as for an end that connects mop rod on the hand-held end of mop rod or plug, and the other end is defined as down) tractive.

For addressing the above problem, people have made multiple trial from many aspects, and have certain effect.Wherein a kind of method is that cloth or cotton cord are seamed in together, to avoid single cloth or cotton cord, deviates from.Although this method has certain effect, sew up relatively holding time of process, and be only suitable for manually completing, cost of labor is high.

Another kind method is to tie up with nail, cloth further to be followed closely on mop rod again afterwards, two problems that this method can once solve that the cloth slippage falls or integral body is trackslipped, but be only applicable to wooden mop rod, and also to the cotton cord weak effect, the scope of application is little.

Another method is to replace the bundle rope to tie up with sufficiently rigid iron wire.The problem that this method gets loose in the time of can effectively solving the knotting of bundle rope, still, the hardness of iron wire can be given to tie up and be made troubles, and the metal high expensive.

Summary of the invention
