Spraying Device With Liquid Adjustment Mechanism
First Claim
1. A sprayer comprising:
- a casing for giving said sprayer form and supporting the following working elements of said sprayer;
two containers for holding a first liquid and a second liquid, respectively, said containers being attachable and detachable, allowing for their replacement,a spraying system, said spraying system comprising a pump for dispensing a mixture of said first liquid and said second liquid,flow adjustment structure, said flow adjustment structure comprising;
two feeding tubes, each of said feeding tubes having a first end and a second end, said first end of each of said feeding tubes being in airtight fluid communication with a respective one of said containers, said second end of each of said feeding tubes having a flexible portion, each said flexible portion having a flow passage with a cross-sectional area and having a flow passage with a cross-sectional area and being connected to said pump for discharging a mixture of said first and second liquids uptaken from said containers,two flow adjustment members which function to selectively control the proportion of said first liquid and said second liquid in the mixture being dispensed such that there is an inversely proportional relationship between the amount of said first liquid and the amount of said second liquid in the mixture.

Abstract
The present invention relates to a fragrance or paint sprayer. The sprayer, comprises a spraying mechanism, two liquid containers, a liquid adjustment mechanism; the spraying mechanism having a knob for activating a pump or a release valve for dispensing a liquid coming from an inlet to an outlet; two liquid feeding tubes, one end of each of the two liquid feeding tubes being in liquid communication with each of the two liquid containers respectively, and the other end of each of the two liquid feeding tubes being jointed and connected to the inlet of the spraying mechanism; the liquid adjustment mechanism comprising two sets of adjoining sloped surfaces and sets of rollers in surface contact with respective flexible portions of each of two liquid feeding tubes and, when the rollers are moving from right to left, changing flow passage areas inside the flexible portions in such a way that the amount of liquid supplied from each of the two liquid containers through each of the two liquid feeding tubes is adjusted. When flow of liquid from one feeding tube is increased by the adjustment mechanism, the flow from the other feeding tube decreases in a way that the total amount of the liquid supplied by the two feeding tubes is substantially constant. In practice, it is possible to mix two liquids, such as two different perfumes with different fragrances to create a new fragrance, or two different color paints to create a new paint color.
