A floor washing machine with dynamically adjustable water tank volume

Abstract

The invention discloses a ground washing machine with the dynamically-adjustable water-tank volume. A water tank is arranged above a bottom frame and comprises a wastewater tank body and a clear water tank body; an opening is formed in the upper portion of the wastewater tank body, the wastewater tank body is provided with a tank cover for sealing the opening in the wastewater tank body, and a wastewater discharging pipe extending outside a ground washing machine body is communicated to the bottom of the wastewater tank body; one end of a wastewater absorption pipe is communicated with a water scraping harrow, and the other end of the wastewater absorption pipe penetrates inside the wastewater tank body; the clear water tank body is arranged inside the wastewater tank body, one end of a clear water pipe penetrates through the wastewater tank body to be communicated with the bottom of the clear water tank body, the other end of the clear water pipe extends above a brushing disc, a water absorption draught fan is arranged on the outer side of the water tank, an air inlet in the water absorption draught fan is communicated with the inside of the wastewater tank body through a pipe, and an overflowing valve is arranged inside the wastewater tank body and arranged at an air absorption opening in the water draught fan; the water tank is divided by an adjusting partition plate inside the water tank in to the wastewater tank body and the clear water tank body, the partition plate is driven in the mode that a screw rod is matched with a sliding pair fixed arranged on the adjusting partition plate, and the screw rod is driven by a motor. By means of the ground washing machine, dynamical adjustment of the water-tank volume can be achieved, and the usable volume of the water tank is maximized accordingly.

Description

technical field [0001] The invention relates to a floor washing machine with a dynamically adjustable volume of a water tank. Background technique [0002] The floor washing machine is a kind of cleaning equipment suitable for a variety of floors. Its main operation methods are hand push type and driving type. Under the action of the water suction fan, the scraper rake absorbs the scrubbed sewage into the sewage tank for storage, and discharges it through the sewage pipe in a concentrated manner, so as to achieve the effect of efficient cleaning of the ground. [0003] The floor washing machine is usually equipped with two water tanks, namely the sewage tank and the fresh water tank. During the washing operation, the water in the clean water tank is discharged to the brush plate for cleaning operations. The cleaned sewage passes through the cavity attached to the wiper rake. is sucked into the waste water tank. The volumes of the existing sewage tanks and clean water tanks...

AI Technical Summary

Problems solved by technology

The volumes of the existing sewage tanks and clean water tanks are fixed. Under the premise of ensuring the continuous operation time and area, the volume of the clean water tank and the volume of the sewage tank should be set as large as possible, which will not only increase the The space volume of the whole machine is increased, the manufacturing cost of the whole machine is increased, and it is not convenient for the transportation of the washing machine. In addition, when the overall volume of the washing machine is large, the working environment will be restricted, which will reduce the general use of the washing machine. sex
