Floor-mopping cloth tensioning mechanism and floor mopping machine

Abstract

The invention provides a floor-mopping cloth tensioning mechanism and a floor mopping machine. The floor-mopping cloth tensioning mechanism is applied to the floor mopping machine. The floor mopping machine includes floor mopping cloth and a machine body, the floor-mopping cloth tensioning mechanism is arranged on the machine body, and the floor-mopping cloth tensioning mechanism and the machine body are both sleeved with the floor mopping cloth; the floor-mopping cloth tensioning mechanism includes a fixing frame, a tensioning wheel and an elastic part, wherein the fixing frame is arranged on the machine body and can do reciprocating motion, the tensioning wheel is mounted on the fixing frame and can rotate around the fixing frame, and the elastic part is arranged on the machine body and faces one side of the fixing frame; under a working condition, the fixing frame compresses the elastic part, the floor mopping cloth is subjected to counter-acting force of the elastic part on the fixing frame and keeps tensioned. By the adoption of the floor-mopping cloth tensioning mechanism, the floor mopping cloth can have enough tensioning force, it is ensured that enough friction is generated between the floor mopping cloth and the floor, and the cleaning effect of the floor mopping machine is improved; meanwhile, even though slightly shaped or lengthened, the floor mopping cloth can be compensated through the floor-mopping cloth tensioning mechanism so that normal word cannot be influenced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a mopping cloth tensioning mechanism and a mopping machine. Background technique [0002] In order to solve the problem of carpet cleaning, vacuum cleaners were introduced in western countries, and based on these, vacuum cleaner robots were launched at the end of the 20th century. At present, the cleaning methods of sweeping robots are mainly divided into two-stage and three-stage. The two-stage type is to raise the dust through the side brush and then inhale it through the rear-end suction port to achieve the purpose of cleaning; the three-stage type is the cleaning structure of "side brush + roller brush + suction port". Compared with other two-stage types For products with a cleaning structure, the key point is to add a roller brush between the side brush and the suction port. The purpose is to sweep up the dust that is electrostatically adsorbed on the ground through the ...

AI Technical Summary

Problems solved by technology

They all need to raise the pollutant dust through the side brush or roller brush and then inhale it to achieve the purpose of cleaning. Therefore, this technology has its limitations that cannot be avoided in principle: 1. For extremely small pollutants or wet ground, due to pollution Objects cannot be lifted up well, so the cleaning effect is very poor; 2. The hair on the ground is often entangled on the side brush or roller brush, which affects the cleaning effect and even causes the machine to be stuck

However, this method requires the use of a mopping cloth with suitable elasticity and sufficient service life: if the elasticity is too large, that is, the mopping cloth is too soft, even if the mopping cloth is tensioned, there will be no gap between the driving wheel and the mopping cloth. Sufficient pressure; if the elasticity is too small, the dimensional design accuracy of the mopping cloth is relatively small, and even a small permanent plastic deformation on the mopping cloth during use will make it invalid and unable to drive
