Abstract
A pump that dispenses measured liquids in a consistent proportional amount includes a plurality of cylinders, a plunger associated with each cylinder and a lever operatively connected to each plunger. Each of the cylinders is connected to a container having a chemical by an input tube. Each cylinder is also connected to a single outlet tube via a plurality of outlet tubes. The cylinders are sized and positioned to dispense a consistent proportional mixture regardless of the length of stroke of the handle.
Description
- This invention is directed toward a pump. More specifically, and without limitation, this invention relates to a pump that dispenses measured liquids in a consistent proportional amount regardless of the length of stroke of a handle.
- Equipment and chemicals used for decontamination and disinfection of residences, business offices, industrial spaces, shipping facilities, food plants, health care offices, schools and the like are known in the art. With the outbreak of Covid-19, the need for disinfection are greater than ever before in order to provide a safe, virus-free work and home environment for employees and families.
- The product DECON7 (D7) is a powerful and effective decontaminant, disinfectant, sanitizer, cleaner and deodorizer for a multitude of applications in various industries. D7 is a patented, EPA registered disinfectant, surface sanitizer, deodorizer and chemical cleaner having a multi-part aqueous solution including hydrogen peroxide and an advanced four-chain quaternary ammonia formulation, making it practical for food production environments, public safety and military situations.
- The process of making D7 is time consuming, labor intensive, and requires safety precautions. Before mixing one must wear a protective apron, googles and gloves. Then, using measuring cups, to make one gallon of mixture, forty-nine fluid ounces of a first part is measured and poured into a mixing bucket. Then forty-nine fluid ounces of a second part is measured and poured into the mixing bucket, followed by two fluid ounces of a third part being measured and poured into the mixing bucket. Using a stirring stick, the mixture in the mixing bucket is stirred for fifteen to twenty seconds and then the mixture is poured into a dispensing device. Finally, the measuring cups, the mixing bucket and the stirring stick are washed. While the process produces a mixture having the correct proportion of the different parts, a better way is desired.
- Accordingly, an objective of the present invention is to provide a pump that dispenses measured liquids in a consistent and proportional amount.
- Another objective of the present invention is to provide a pump that mixes and dispenses multiple chemicals in a safe and easy manner.
- These and other objectives will be apparent to those skilled in the art based upon the following written description, drawings and claims.
- A pump for dispensing measured liquids in a consistent proportional amount includes a plurality of cylinders where each cylinder has a plunger that extends into and is disposed within the cylinder. Operatively connected to the plungers is a lever having one or more elongated members. The cylinders are disposed within a housing and the lever extends through a side wall in the housing.
- Each of the cylinders is connected to a container having a chemical by an input tube. Each of the cylinders is also connected to an output tube which extend to and are connected to a single output tube. The single output tube is connected to a dispensing device.
- The cylinders are sized and positioned such that when the lever is moved in one direction chemical from the containers is drawn into the cylinders via the input tubes. When the lever is moved in the opposite direction the chemical is drawn into the output tubes and flows to the single output tube to the dispensing device. Based upon the size and position of the cylinders the pump dispenses measured liquids in a consistent proportional amount regardless of the length of the stroke of the lever.
-
FIG. 1 is a perspective view of a pump; and -
FIG. 2 is a front view of a pump. - With reference to the figures a
pump 10 includes a plurality ofcylinders 12, and preferably three cylinders operatively connected to alever 14. More specifically, thelever 14 is pivotally connected to a plurality ofplungers 16 at one end and eachplunger 16 extends into and is slidably received within eachcylinder 12. Thelever 14 is of any size, shape, and structure and in one example has twoelongated members 18 that extend in parallel spaced relation and have ahandle 19 that is connected to and extends between themembers 18 at one end. Preferably, thepump 10 is disposed within ahousing 22 having aback wall 24,side walls 26, and adoor 28 opposite the back wall that is hingedly connected to one of theside walls 26. Also, one of theside walls 26 has one ormore slots 30 through which the elongated member(s) 18 extend. Thelever 14 is pivotally connected to thehousing 22 at one end. - A plurality of
input tubes 32 extend through aside wall 26 and are connected to one end of thecylinders 12. Anoutput tube 34 is connected to each of thecylinders 12 at one end and to asingle output tube 36 at the other end. Thesingle output tube 36 extends through theside wall 26. Each of theinput tubes 32 are also connected to acontainer 38, such as a bottle, that contains a chemical. Thesingle output tube 36 is connected to adispensing device 40 such as a nozzle or the like. Thecylinders 12 are of different sizes and positioned along theelongated members 18 so that they draw in and dispense an amount of chemical that corresponds to a desired proportion for a mixture of the different chemicals. Theinput tubes 34 andoutput tube 36 havecheck valves 20 that control the flow of fluid based upon the stroke of thecylinder 12. - In operation, the pump is activated by moving the
lever 14 from a first position to a second position which causes theplunger 16 to draw different chemicals from thedifferent containers 38 intodifferent cylinders 12 via theinput tubes 32. Thecheck valve 20 on theoutput tube 36 prevents flow to theoutlet tube 36. The movement of thelever 14 calibrates the volume in eachcylinder 12 and thecheck valves 20 keep thecylinders 12 primed and capable to work as pumps. Eachcontainer 38 is connected to acylinder 12 having a size that corresponds to a predetermined percentage of a mixture. For example, if there are threecontainers 38 and the predetermined mixture is 49:49:2, then two of thecylinders 12 are twice as large as the third. As such, not only based upon the size, but also the position of thecylinder 12, the amount of chemical drawn into the twolarger cylinders 12 is twice as much as in the third cylinder. When thelever 14 is moved from the second position to the first position chemicals are drawn out of thecylinder 12 by the plunger and into theoutput tubes 34. Thecheck valve 20 on theinlet tube 34 prevents flow back through theinlet tube 34. The amount of chemical dispensed from the cylinder is based upon the size and position of thecylinders 12. In the example above, twice as much chemical would be dispensed from the twocylinders 12 as compared to thethird cylinder 12. The chemicals then flow throughoutput tubes 34 to thesingle output tube 36 where the chemicals are mixed at their desired proportion and the mixture flows through thesingle output tube 36 to thedispensing device 40. - Accordingly, a
pump 10 has been provided that dispenses multiple measured liquids in a consistent proportional amount regardless of the length of the stroke of the lever, and improves upon the art. - From the above discussion and accompanying figures and claims it will be appreciated that the
pump 10 offers many advantages over the prior art. It will be appreciated further by those skilled in the art that other various modifications could be made to the device without parting from the spirit and scope of this invention. All such modifications and changes fall within the scope of the claims and are intended to be covered thereby. It should be understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in the light thereof will be suggested to persons skilled in the art and are to be included in the spirit and purview of this application.
