Device and method for automatically mixing and refilling automotive windshield cleaning fluid

Abstract

The invention discloses a device and method for automatically mixing and refilling automotive windshield cleaning fluid. Two ends of a water pump are connected in parallel with a liquid return pipe; afirst extraction solenoid valve is arranged on the liquid return pipe; a liquid drain pipe is led out between a liquid return pipe communicating end on a filling pipe and the water pump; a second extraction solenoid valve is arranged on the liquid drain pipe; a first filling solenoid valve is arranged between a liquid return pipe communicating end on an output pipeline and a mixed finished product barrel; a second filling solenoid valve is arranged between a liquid return pipe communicating end on a filling pipe and a liquid drain pipe lead-out end. With the adoption of the liquid return pipeand the liquid drain pipe and in combination with opening fit of four solenoid valves, old cleaning fluid is pumped back and then new fluid is filled, the automotive windshield cleaning fluid in an automotive windscreen wiper is completely replaced, secondary pollution caused to the new filled automotive windshield cleaning fluid is avoided, the probability of deterioration of concentrated automotive windshield cleaning products occurring during use is reduced, the running safety is improved, and the device is convenient to use and cost-saving.

Description

technical field [0001] The invention relates to the field of automobile windshield cleaning products and adding methods, in particular to a device and method for automatic mixing and pumping of automobile windshield cleaning fluid. Background technique [0002] Automobile windshield cleaning product refers to a chemical product that is filled into the automobile wiper pot and can be sprayed onto the automobile glass to cooperate with the wiper to clean the automobile windshield and keep the driver with a good vision . [0003] Existing car windshield cleaning products can be divided into three types according to their manufacturing process: [0004] 1. Ordinary car windshield cleaning products, this kind of car windshield cleaning fluid can be directly added to the car's wiper pot for use; the disadvantage is that the ratio of additives and water has been prepared before leaving the factory, which is prone to deterioration and Precipitation, short product shelf life; [0...

AI Technical Summary

Problems solved by technology

[0004] 1. Ordinary car windshield cleaning products, this kind of car windshield cleaning fluid can be directly added to the car's wiper pot for use; the disadvantage is that the ratio of additives and water has been prepared before leaving the factory, which is prone to deterioration and Precipitation, short product shelf life;

[0005] 2. Concentrated car windshield cleaning products. This kind of cleaning solution needs to be mixed and diluted with a specified proportion of water before it can be added to the car's wiper pot for use; the disadvantage is that the components of the products of each manufacturer are different, and after mixing with each other It is more prone to deterioration and precipitation, which affects the cleaning effect;

[0006] 3. Solid car windshield cleaning products, such as effervescent tablets, this solid product needs to be dissolved in water before use; the disadvantage is that it is not easy to brew and add, and the cleaning effect is weak

[0007] This article only discusses concentrated car windshield cleaning products, because these products often contain alcohol components, dark color and strong smell. It will be damaged, and it will cause color difference in the plastic parts of the car, and it will harden or even swell the rubber parts of the car

[0008] In addition, the deteriorating car windshield washer fluid also loses the ability to lower the freezing point of the liquid, and is more likely to be frozen in winter, which leads to the failure of the water spray can pump
