    DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

    (19) The preferred embodiment of the instant invention provides for an airless electronic utilitarian mobile spray pack for use as an aid for window tinting as well as paint protection film (PPF) application, vinyl wrapping, detailing, window washing, HVAC and concrete finishings. The instant inventor has been a leader in the industry since 2020 and has significantly increased the utility and safety of the invention with specialized additions.

    (20) The instant invention incorporates a inch spray hose for higher pressure output and greater conservation of liquid in the device. Specialized quick connectors have been incorporated into the connection of the hoses to the pump. Furthermore, a specialized bladder has been included that can contain four or more liters of fluid. A back compartment has been added that incorporates insulated thermofoil for the compartment in which the bladder is housed. This allows for whatever liquid is used to remain cool or hot, depending on the application.

    (21) Worm style hose clamps on prior art devices can loosen over time and create fluid leakage which can be dangerous in close proximity to electronic components. The hose clamps in the instant invention are crimped to alleviate this hazard. Additionally, clamp heat shrink is used to protect the clamps, thereby minimizing or avoiding entirely the risk of snags and damage. The aforementioned stainless steel hose quick connectors aid in the ability to disconnect the hose in case of need for repair and also allows for the flexibility of the easily change out of different length hoses, depending on the application.

    (22) Also mentioned previously, the inch spray hose saves weight and fatigued on the user compared to larger diameter hoses, which are heavier and more restrictive. In the instant system and inch hose is used to connect the pump to the bladder for a fast fill whereas the inch hose allows for fluid to exit the bladder into the spray house under higher pressure while conserving fluid, as well as being more lightweight.

    (23) The pump of the instant invention is also a specialized improvement in the system. It is a 12 volt 90 psi reinforced diaphragm pump that has a 4-screw head and nylon reinforced body plate covers. The backpack itself has custom molded hard shell compartment covers protecting the vital components housed therein. Inside of these compartments are dedicated sleeves for the custom battery (top compartment) and the pump (bottom compartment). The controller is housed directly next to the battery for connection thereto with a hole that allows for the wires to be routed into a specialized safety intermediate compartment where the wiring is all segregated from the compartment that houses the bladder containing liquids, thereby greatly improving safety.

    (24) The controller is also specialized in that it contains a custom made on/off switch with a PCM circuit board to regulate the voltage, thereby providing improved safety. An LED level indicator lets the user see the level of charge on the battery and whenever a recharge is required. The battery itself is a lithium ion battery has a custom shape to be charged in its own custom charger. A battery pouch/sleeve housed in the top, front compartment allows for securement of the battery therein away from other components but also allows for easy removal for charging. This is an enhanced safety feature over prior art flat battery packs with a wall charger.

    (25) A magnet is incorporated in the system to secure the spray trigger which is made of metal and will secure itself to the magnet. The magnet holds the spray trigger in its holster and prevents it from slipping out. The brass trigger on the spray nozzle improves longevity and provides for a smaller, easier grip than those found on a polymer plastic sprayer typically used in the prior art.

    (26) The backpack itself is made with durable materials and dedicated reinforced compartments with hard shell lids with reinforced military stitching as well as custom molded comfort back pads on the back as well as ventilated foam pads on the back.

    (27) Mentioned previously, the four plus liter bladder is larger than anything in the prior art and is outfitted with a large screw cap that is more secure than prior art bladder caps. Around the screw cap is a hook that allows for the bladder to attach to a hook and loop clasp in the bladder compartment so it remains vertically upright and does not collapse inside the compartment.

    (28) Mentioned previously was the dedicated compartment for the wiring to be segregated from the rest of the back pack. This compartment provides water resistance for the wire connections and keeps them hidden and out of the way, which makes for a safer and cleaner orientation.

    (29) Adjustable side straps and a front padded harness better secure the pack onto the user and keeps the pack higher on the back which is more ergonomic for the user versus a pack that hangs lower on the back. There are also dedicated drainage ports on the bottom of the pack for the two inner compartments in the case that liquid should leak, the liquid can exit the pack safely instead of filling the pack with water potentially damaging the electronic components.

    (30) Hose keepers in the form of plastic over the shoulder hook and loop rings inside the pack secure the hoses throughout the pack to secure the hoses and keep them out of the way. Custom made brass swivels with chemical resistant seals are used for both the inch and in hoses. Finally there is a custom PVC grip carry handle on the top of the pack.

    (31) Turning to the drawings, the preferred embodiment is illustrated and described by reference characters that denote similar elements throughout the several views of the instant invention.

    (32) FIG. 1 shows the specialized controller 42 of the instant invention which connects the battery 34 to the pump 50.
