Intelligent wall brush tool with amplification circuit

Abstract

The invention discloses an intelligent wall brush tool with an amplification circuit. The intelligent wall brush tool comprises a base, a sliding track, a support rack, a roller brush, a bucket and a baffle plate, wherein the sliding track is arranged on the base; the support rack is arranged on the sliding track; the roller brush is arranged at the top of the support rack; the roller brush is connected with the support rack through a bearing; the bucket is arranged on the support rack; the baffle plate is arranged at the bottom of the support rack, and is a telescopic plate; a pressure sensor is arranged at the front end of the baffle plate; a controller and a power supply module for providing a direct-current power supply to the controller are arranged on the support rack; the sampling circuit, a filtering circuit and an amplification circuit are connected between the pressure sensor and the controller; the application circuit comprises an operational amplifier U1 and an operational amplifier U2; same-phase input ends of a resistor R1 and the operational amplifier U1 are connected in series. The intelligent wall brush tool has the advantages that the efficiency is improved, resource waste can be reduced, and wall paint can be prevented from being dropped to a floor or a skirting line.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an intelligent wall brushing tool with an amplifying circuit. Background technique [0002] At present, when decorating, most of the paint is painted with a roller brush. When painting, there is a problem that the wall paint drips to the bottom and the top of the baseboard, so there is a problem that it is difficult to clean. Although it can be cleaned on the ground and the baseboard Covered with a protective film, the protective film is mostly disposable, and it is troublesome to lay, and there are problems of low efficiency and waste of resources. Contents of the invention [0003] The object of the present invention is to solve the above problems and propose an intelligent wall-painting tool with an amplifying circuit to achieve the advantages of improving efficiency and reducing waste of resources while preventing wall paint from dripping onto the ground and skirting bo...
