Wiping free car washer

Abstract

This invention discloses a kind of a non-manual car-wiping machine, which consists of mechanical part and circuit-control part. The mechanical part includes source case and water case that are connected through a pipe and a mixing device. The pipe between the source case and the mixing device is connected with the source controlling valve and source flow valve while the pipe between the water case and the mixing device is connected with a water-controlling valve and a flow valve. In the middle of the source valve and the flow valve is fixed a flow sensor. The mixing device is connected with a liquid-storing case through a pipe. There is a sense device for the liquid level. The circuit-control part includes microcomputer control chip, through which the ON / OFF switch of the source controlling valve and the water-controlling valve is controlled after the signal from the sense device for the liquid level can be received, and thus the liquid level in the liquid-controlling case is under control. Between the liquid-storing case and the spray gun there is a mixing liquid-squirting electric machine with a high pressure. This invention, the non-manual car-wiping machine, owns a simple structure which can efficiently distribute the mixing liquid and passes it into the liquid-storing case in time, besides this it can enhance the matching accuracy of source liquid and water.

Description

【Technical field】 [0001] The invention relates to a cleaning device, in particular to a wiping-free car washing machine for cleaning cars. 【Background technique】 [0002] In the past, car cleaning was mainly done by scrubbing with washing liquid, then rinsing with clean water, and finally drying. This method needs to use sponge, towel, or car wash gloves to scrub the paint surface of the car body, so it is easy to cause scratches and abrasions on the paint surface. In addition, the dirt in each corner of the car, tires, chassis and car seams is not easy to remove; and there are deficiencies in cleaning labor intensity, long time, waste of water resources, and environmental pollution. So now some companies have developed a wipe-free car washing machine. [0003] A wiping-free car washing machine can refer to the Chinese patent No. ZL 02272265.3, which discloses a wiping-free car washing machine, which is composed of a housing, a mechanism part and an electrical control part....

Problems solved by technology

[0004] However, since the mixer of the wipe-free car washing machine is located in the liquid storage tank, only when the liquid level of the liquid storage tank reaches the lowest level, under the action of the buoyancy switch, the water power pump and the raw liquid power pump start to work. The preset flow rate of the valve is automatically proportioned and mixed through the mixer, so it is easy to cause the mixed liquid to not be replenished to the liquid storage tank in time, and it is easy to cause the mixed liquid to be used without being fully prepared; in addition, because it uses mechanical The ratio of stock solution and water is adjusted in a certain way, so the ratio is not accurate, which may lead to unclean cleaning; and the structure of the wipe-free car washing machine is complicated
