Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] Keeping cool in any hot environment can be challenging. Water has long been recognized as a preferred means for cooling, but carrying and using water to cool a person is a challenge. Misting water assists further in cooling and requires less water. Portable personal misting devices, though, are a further challenge, especially without using electrical powered delivery. Additionally, a proper mist requires significant pressure, something few portable powering devices can effectively supply. The current invention solves these problems. FIELD OF THE INVENTION [0002] The current invention relates to water misting devices and more specifically to a portable personal water misting apparatus with counter pressure delivery. SUMMARY OF THE INVENTION [0003] The general purpose of the personal water misting device with counter pressure delivery, described subsequently in greater detail, is to provide a personal water misting device with counter pressure delivery which has many novel features that result in an improved personal water misting device with counter pressure delivery which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof. [0004] The personal pressurized water misting apparatus with counter pressure delivery is comprised of a rigid reservoir with a flexible bladder within. The bladder is designed to hold water. The bladder is acted upon by a movable pressure shelf. The pressure shelf moves within the length of the reservoir. One example of the invention offers a flexible, bendable bladder. This example allows edges of the bladder to fold as needed in passing the edges of the pressure platform. Other examples employ a flexible, expandable bladder such that the bladder expands and contracts within the reservoir and below the pressure shelf as needed with the influx and outflow of water. One example of the invention is supplied as a backpack. Yet another example is supplied as a belt with the reservoir positioned as chosen. A filler with a check valve is conveniently disposed on all examples of the invention. A filler cap covers the filler. A one way check valve resides just within the filler. The check valve is in sealed communication with the bladder. The filler is a threaded female fitting. The fitting is a typical water hose female fitting. The female hose fitting is designed to accept a typical water hose threaded male fitting. [0005] A water hose is used to fill the bladder of the invention. Water hoses typically supply water pressure from 35-100 pounds per square inch (psi). [0006] A pressure shelf is disposed within the reservoir. A compression spring is anchored within the reservoir. Still other examples of the invention utilize more than one spring. In the backpack example of the invention, each spring is anchored against the inside of the top of the reservoir in a spring rest. The opposite end of each spring is anchored in a spring rest against the pressure shelf. In the waist belt example of the invention, the spring is anchored against in inner end of the reservoir opposite the filler end. The spring is between the end of the reservoir and the pressure shelf. The pressure shelf acts against the bladder to pressure the water contained within the bladder. As water hose is used to fill the bladder. Water pressure presses against the pressure shelf. The spring is thereby compressed. Spring compression ceases when pressure within the bladder equals water pressure from the hose supplied to the invention. The air within the reservoir but not within the bladder is compressed. Therefore the springs and the air pressure are imposing an expansion force against the pressure shelf. When internal pressure equals that of the water pressure applied, the check valve sees equilibrium and closes. Withdrawing the water hose from the invention therefore does not allow water flow out of the invention. [0007] In an additional example of the invention, the pressure within the bladder is further enhanced by a handle operated mechanism. The mechanism is used after the bladder is filled with water. [0008] The handle operated mechanism comprises a handle external to the reservoir. The handle is generally T-shaped. The handle extends into a sleeve. The sleeve passes through the reservoir top. The passage of the sleeve through the reservoir is fitted with a seal. Air pressure is prevented from escaping from the reservoir by the seal. A plunger is fitted to the sleeve, within the reservoir. As the handle is pushed inward toward the reservoir, the plunger compresses the spring circling about the handle sleeve. The sleeve is guided by a rod that slideably fits within the sleeve. The rod is anchored to the pressure shelf. The sleeve exterior to the reservoir is fitted with a perpendicularly affixed t-lock. The top of the reservoir exterior is fitted with a lock tab. The lock tab accepts the t-lock of the sleeve. The T-handle is pushed into the reservoir until the t-lock is aligned with the abbreviated lock tab. The t-lock is then twisted. The sleeve and handle are thereby held in a position which compresses the spring within the reservoir, thereby retaining the spring pressure resulting from compressing the plunger against the spring force. This additional spring pressure provides for the plunger to exert more pressure against the pressure shelf, thereby further pressuring the water held within the reservoir bladder to a psi greater than what only the water pressure filling can provide. [0009] The filling water pressure exerts pressure against the pressure shelf, such that pressurized filling of the bladder moves the pressure shelf, thereby compressing springs within the bladder, whereby counter pressure delivery is actuated with the on/off control. The on/off control is fitted within the flex tube. The flex tube exits the bladder and passes outside of the reservoir. [0010] The flex tube provides for positioning the delivery of water from the bladder as desired. One example of the invention provides a misting nozzle at the end of the flex tube. The misting nozzle is, in one example, fitted to the top of a hat. Turning on the on/off control allows for water pressure to force water into the misting nozzle, thereby spraying water mist above and outward from the top of the hat. The on/off control offers graduated opening such that mist volume is controlled. Still another example of the invention offer a stream nozzle with a trigger. The water stream provided is controlled by the trigger, much as a typical water gun. Various other nozzles and water deliveries are provided. [0011] The invention therefore offers counter pressure delivery of water in mist or stream form. The reservoir's internal compression of air and springs by the pressurized introduction of water stores the potential energy. The examples of the invention featuring added spring pressure via the plunger and handle further store additional energy. The on/off control provides for releasing that stored energy by forcing water out through the delivery system. No pumping or electric pumps are required. [0012] Thus has been broadly outlined the more important features of the personal water misting device with counter pressure delivery so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
