A round brush and a high-pressure cleaning machine including it

Abstract

The invention discloses a novel round brush and a high pressure cleaning machine with the same and belongs the fields of cleaning equipment auxiliary parts and machines. The round brush comprises an upper sprayer and a lower sprayer which are mounted fixedly and integrally and which form a spraying cavity; the lower sprayer is fixedly provided with a brush disc provided with a plurality brush hairs, and the brush disc is provided with a plurality of water discharging holes among the brush hairs; the lower sprayer is connected to a water incoming pipe, and the water outlet of the water incoming plate extends into the spraying cavity; the upper sprayer is provided with an air incoming channel communicating with the spraying cavity, and a pressurizer pressurizing the air flow entering the spraying cavity is arranged between the air incoming channel and the water outlet of the water incoming pipe and is located in the spraying cavity. The round brush has the advantages that energy and water are saved, the brushing effect is fine, a vehicle can be protected and the service life is long, and the round brush is widely applied to vehicle washing.

Description

technical field [0001] The invention relates to an auxiliary accessory of cleaning equipment and a cleaning appliance including it, more particularly to a round brush and a high-pressure cleaning machine including it, belonging to the field of cleaning accessories and complete machines. Background technique [0002] With the process of industrialization in our country and the rapid development of the automobile industry, the market share of cars is increasing day by day, and the daily maintenance of vehicles has become a new industry. In the daily maintenance of vehicles, car cleaning is the simplest and most frequent item in vehicle maintenance. [0003] Traditional car cleaning is to manually use some simple cleaning machines to clean the vehicle surface. The nozzles of the auxiliary accessories of these cleaning machines include direct spray, vertical brush, disc brush and so on. When in use, high-pressure water is sprayed to the car body through the nozzle from the clea...

AI Technical Summary

Problems solved by technology

Although the upper structure of the water wheel is adopted, the output torque center is as close as possible to the rotating brush, thereby improving the transmission efficiency and working stability, and simplifying the transmission mechanism, but this rotating part is easily damaged during use. However, its service life is short, and in actual use, the rotation of the brush can easily cause scratches on the surface of the car body. When hard substances such as sand or stones are attached to the surface of the car body, the rotating brush will make the car body The paint on the surface of the body is damaged. At the same time, the high-pressure water hits the water wheel to do work, which reduces the potential energy of the high-pressure water, thereby reducing the scouring effect.

[0006] The description of Chinese utility model patent CN200947901Y discloses a kind of interchangeable rotary disc round brush, which includes a shell, a large brush placed on the shell shell, an impeller and a rotary disc round brush installed on the polygonal gear shaft, placed on the large brush The transition gear on the bracket, as well as the brush handle and nozzle, the sleeve of the round brush on the turntable is set on the polygonal gear shaft, and the polygonal gear shaft is meshed with the transition gear. There is a boss on the inner wall of the bushing of the round brush, and the three-claw elastic locking piece clamps the boss to make the round brush of the turntable assembled and fixed. The straight pull method fixes the turntable, so that the round brush rotates reliably, is easy to assemble and disassemble, and is easy to replace. However, there are also defects that the rotating parts are easy to be damaged and scratch the car body during use.
