Cleaning robot

Abstract

The invention relates to the field of cleaning instruments, in particular to a cleaning robot. The robot comprises a water tank, a brush disc mechanism and a water suction mechanism, the brush disc mechanism comprises a brush disc and a water spraying pipe, an inlet of the water spraying pipe is communicated with the water tank, an outlet of the water spraying pipe is formed in the brush disc, andthe water suction mechanism comprises a water suction rake, a sewage suction pipe and a suction fan arranged on the water tank, an air inlet of the suction fan is communicated with the water tank; the water suction rake is connected with the water tank through a sewage suction pipe, the water tank is a single water tank, a filter cartridge is arranged in the water tank, two spaces are formed inside and outside the filter cartridge in the water tank, one space is used as a clear water area, the other space is used as a sewage area, the sewage suction pipe sucks sewage into the sewage area, andthe water spray pipe is communicated with the clear water area. Only one water tank needs to be designed to contain clean water and sewage at the same time, a power device for sewage to flow to the clean water is omitted, the structure is simplified, and cost is reduced.

Description

technical field [0001] The invention relates to the field of cleaning instruments, in particular to a cleaning robot. Background technique [0002] The washing machine is a kind of cleaning robot. After years of development, the current washing machine technology is relatively mature. The principle is to spray clean water from the clean water tank to the ground on the one hand, and recover the sewage on the ground and filter it on the other hand. Circulate to the clean water tank, so the floor washing machine is generally equipped with two boxes, the clean water tank and the dirty water tank. Device, the filtered water in the sewage tank is input to the clean water tank through the filter pump. [0003] For example, the Chinese Patent Authorization Announcement No. CN106638421B, the authorized announcement date is 2019.06.14, and the patent titled "A Floor Scrubber with Dynamically Adjustable Water Tank Volume" discloses a floor scrubber with dynamically adjustable water ta...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the shortcomings of the clean water tank and the dirty water tank in the floor washing machine of the prior art, which are divided into two boxes, the structure is complex and the cost is relatively high, the purpose of the present invention is to provide a cleaning robot with only one water tank designed to accommodate clean water at the same time and sewage, while eliminating the power device for sewage to flow to clean water, simplifying the structure and reducing costs
