DETAILED DESCRIPTION OF THE INVENTION

[0013] Please refer to the drawings.

[0014] As illustrated in FIGS. 1 and 2, the present invention, Portable Blower, comprises a convenient method for removing leaves, debris, and eliminating snow and ice on driveways, walkways, steps, and vehicles.

[0015] In a primary embodiment shown in FIG. 1, indicated at 10, Portable Blower consists of a molded plastic housing 12, containing an engine for propelling air of any suitable design, such as electric or gas two-stroke engine, as is well known in the art. Housing 12 additionally contains a heating element of any suitable design, such as electric resistance coil, ceramic element, or gas burner, as is well known in the art. Housing 12 features main switch 14. Actuating main switch 14 turns the power on and off. Housing 12 also features handle 18, by which the user conveniently carries and directs Portable Blower 10. Handle 18 features heat switch 16. Actuating heat switch 16 turns the heating element on and off. Housing 12 also features vent 22, allowing for air intake. Housing 12 also features heat control 26. At the rear of housing 12 is located power cord connection 24, allowing for power supply. The front of housing 12 features molded telescoping nozzle 28, allowing for air output.

[0016] When main switch 14 is turned to the on position, power supplied by power cord connection 24 activates the engine, causing air to be taken in through vent 22 and propelled through molded telescoping nozzle 28. The user directs the flow of air according to their needs by directing the nozzle toward the area to be blown by means of handle 18. When appropriate, actuating heat switch 16 to the on position directs power to the heating element, which heats the air taken in through vent 22 before it is propelled through molded telescoping nozzle 28. When heat switch 16 has been actuated, the user adjusts the temperature by turning heat control 26 to the desired level.

[0017] In an alternate embodiment shown in FIG. 2, and indicated at 30, a rechargeable Portable Blower is additionally equipped with rechargeable battery 54 and strap 52 for enhanced range and ease of portability. Portable Blower 30 additionally consists of rechargeable housing 32, containing an engine for propelling air of any suitable design, such as electric or gas two-stroke engine, as is well known in the art. Rechargeable housing 32 additionally contains a heating element of any suitable design, such as electric resistance coil, ceramic element, or gas burner, as is well known in the art. Rechargeable housing 32 features rechargeable main switch 34. Actuating rechargeable main switch 34 turns the power on and off. Rechargeable housing 32 also features rechargeable handle 38, by which the user conveniently carries and directs the rechargeable Portable Blower 30, as well as strap 52. Rechargeable handle 38 features rechargeable heat switch 36. Actuating rechargeable heat switch 36 turns the heating element on and off. Rechargeable housing 32 also features rechargeable vent 42, allowing for air intake. Rechargeable housing 32 also features rechargeable heat control 46. At the rear of rechargeable housing 32 is located rechargeable power cord connection 44 as well as rechargeable battery 54, both of which allow for power supply. The front of rechargeable housing 32 features rechargeable molded telescoping nozzle 48, allowing for air output and for directing the direction of air flow.

[0018] When rechargeable main switch 34 is turned to the on position, power supplied by either rechargeable power cord connection 44 or rechargeable battery 54 activates the engine, causing air to be taken in through rechargeable vent 42 and propelled through rechargeable molded telescoping nozzle 48. The user directs the flow of air according to their needs by directing the nozzle toward the area to be blown by means of rechargeable handle 38, while supporting the weight of the unit with strap 52 over their shoulder. When appropriate, actuating rechargeable heat switch 36 to the on position directs power to the heating element, which heats the air taken in through rechargeable vent 42 before it is propelled through rechargeable molded nozzle 48. When rechargeable heat switch 36 has been actuated, the user adjusts the temperature by turning rechargeable heat control 46 to the desired level.

[0019] By allowing for ambient temperature air output as well as heated air output, Portable Blower combines the functionality and convenience of a blower for removal of leaves and yard litter and other debris with the novel capability of melting away snow and ice from driveways, walkways, and personal vehicles. This eliminates the labor and strain of traditional snow- and ice-clearing methods, such as shoveling, scraping, and snow-blowing, and also eliminates the accumulation of shoveled snow by melting it away. Combined with the ability to melt snow and ice from vehicles, Portable Blower is an ideal alternative to traditional methods. The rechargeable capability enhances range of use for maximum convenience when clearing large spaces or extensive walkways and driveways.

[0020] The large-model Portable Blower is preferably gas-powered, while the small-model Rechargeable Blower is preferably electrically powered, either by a rechargeable battery-pack for use away from a power outlet. Or, through the use of an extension cord and standard household current

[0021] The Portable Blower of the present invention removes snow by evaporating the moisture, rather than simply moving it from one place to another. Users accustomed to snow-shoveling will love the lightweight convenience of this nearly labor-free device; and users accustomed to snow-throwers and snow-blowers will also find the Portable Blower or rechargeable blower a better alternative. Simply slip the sling-strap over the neck and shoulder, start the Blower (whether electric or gas-powered), and go, directing a focused, high-speed flow of heated air at the snow or ice on the driveway, the walks, the steps, the car windshield, and so on. The snow and ice will be converted into harmless melted water, and evaporated. No labor to speak of, no fuss: just that simple, just that quick. And because the Blower permits the user to operate the tool with or without heat, this tool is useful the year round: a leaf blower in the fall, a snow-remover in the winter.

[0022] Although this invention has been described with respect to specific embodiments, it is not intended to be limited thereto and various modifications which will become apparent to the person of ordinary skill in the art are intended to fall within the spirit and scope of the invention as described herein taken in conjunction with the accompanying drawings and the appended claims.
