DETAILED DESCRIPTION

Referring to the drawings and, in particular,FIG.1, there is shown a multiple nozzle, nozzle attachment100of the present disclosure. As noted above, the multiple nozzle, nozzle attachment has two nozzle portions called a “dual nozzle” attachment100for the embodiment shown. Dual nozzle attachment100has an opening that is used to connect to the barrel or concentrator of a hair dryer (not shown). Opening105in the embodiment shown inFIG.1, is a circular opening at the proximal or rear end of dual nozzle attachment100. However, in other embodiments, opening105can be other shapes, such as rectangular, square, oval, elliptical, and triangular in order to fit hair dryer barrels or concentrators of similar shapes.

Dual nozzle attachment100has a first or top nozzle110, and a second or bottom nozzle120both placed at the front or distal end of the dual nozzle attachment as shown. Attachment100has a body106tapered from opening105to connect with the first and second nozzles110and120. The tapering includes a tapered portion107and a steep taper portion108. The body portion106has basically a conical shape with a wider circumference at opening105than the circumference at the topmost area where tapered portion107and steep taper portion108meet or where body106connects to nozzles110and120. In this embodiment, nozzles110and120are shaped as rectangular structures having a pair of side walls112and122, respectively, with curved edges114and124respectively, as shown, that together form similarly shaped distal end openings170and180, respectively, at the distal ends or tips. In some embodiments each of the sidewalls112is parallel to each other, and each of the sidewalls122is parallel to each other. In some embodiments nozzles110and120are parallel to each other. In some embodiments the shape of the body106between each of the multiple nozzles conveys air towards the nozzles by tapering the body towards each nozzle.

In other embodiments of the present disclosure, attachment100can have any number of nozzles, such as three, four or five nozzles.

Once attachment100is connected to the barrel of a hair dryer, attachment100alters the air flow exiting the dryer when the dryer is in use. Specifically, the dual nozzle attachment100provides higher exiting air pressure than a single nozzle of equivalent total, effective distal exit area. The total effective distal exit area is the combined area of the distal openings170and180.

Referring toFIGS.2and3, opening105is shown as a circular opening in this embodiment, for connection to a hair dryer with a circular barrel. From opening105, body106tapers to connect to the first nozzle110and second nozzle120.

Referring toFIG.4, opening105is shown at the bottom of the figure. As shown, body106tapers outward and connects to the first and second nozzles110and120, respectively. The distal ends of first and second nozzles110and120have a length101. Length101is shown as the inner length of the distal end openings170and180of nozzles110and120. In this embodiment, length101is about 60 millimeters (mm) or is 60 (mm). It should be noted that length101is the same for first nozzle110and second nozzle120, but in a less preferred embodiment of dual nozzle attachment100, length101can be different for each of the two nozzles.

FIG.5shows, the right-side of dual nozzle attachment100. The left-hand side (not shown) would be a mirror image ofFIG.5. InFIG.5, opening105is shown at the bottom of the figure. Body106tapers to connect to nozzles110and120as shown. Nozzle120is shorter in length than nozzle110. The distal ends or tips of nozzles120and110, respectively, are angled and preferably at the same angle as discussed below.

FIG.6further illustrates the various angles of distal ends or tips at distal end openings170and180of nozzles110and120, respectively. An imaginary dotted line135is shown adjacent and parallel to distal end openings170and180of nozzle110and120. Another imaginary line136is shown adjacent and parallel to the bottom surface of opening105, and perpendicular to the sidewalls112and122. Angle130is formed at the intersection of lines135and136. In the embodiment shown inFIG.6, angle130is 30 degrees.

InFIG.7, first nozzle110is shown at the front and second nozzle120is shown at the rear. Each nozzle110and120tapers, in reverse of the taper of body106, from its greatest width at distal end openings170and180of nozzles110and120, respectively, to the least width or lowest point190of body106that is near, but not at opening105as shown.

Referring toFIG.8, each distal end opening170and180has a width102. In the embodiment shown inFIG.8, width102is about 3 millimeters (mm), preferably 3 mm.

As shown inFIG.9, openings170and180of nozzles110and120, respectively, are visible from the rear view through opening105.

FIG.10shows a second embodiment of a dual nozzle attachment200for a hair dryer according to the present disclosure. In this embodiment, opening205of dual nozzle attachment200is used to connect to the barrel or concentrator of a hair dryer (not shown). Opening205in the embodiment, as shown inFIG.10, is also circular opening at the rear end of dual nozzle attachment200. However, in other embodiments, opening205can be other shapes, such as rectangular, square, oval, elliptical, and triangular in order to fit hair dryer barrels or concentrators of similar shapes.

Attachment200has a first or top nozzle210and a second or bottom nozzle220both placed at the front end of the attachment as shown. Attachment200further has a body206tapered from opening205to connect with the first and second nozzles210and220. In this second embodiment, body206is basically a conical shape with a wider circumference at opening205than the circumference at the topmost area that connects to nozzles210and220. In some embodiments the body206is the same conical body as described above with regards to body106and has similar tapered portions207and208with respect to tapered portions107and108. In this embodiment, nozzles210and220are, similar to the nozzles in the first embodiment, shaped as rectangular structures with sidewalls212and222having curved edges214and224, as shown, and with similarly shaped openings at their distal ends or tips270and280respectively. However, in this second embodiment, unlike the first embodiment, the proximal ends of nozzles210and220terminate at the edge290or very near the edge of opening205as shown more clearly inFIG.12andFIG.14.

In other embodiments of this second embodiment, as discussed above with respect to the first embodiment, attachment200can also have additional nozzles, such as a third, fourth or fifth nozzles. Attachment200provides higher exiting air pressure than a single nozzle of equivalent total, effective distal exit area. The total effective distal exit area is the combined area of the distal openings270and280.

As shown inFIGS.11and12, in dual nozzle attachment200of this embodiment, opening205is, as shown, a circular opening for connection to a hair dryer with a circular barrel. Body206tapers to connect to first nozzle210and second nozzle220.

FIG.12shows a bottom, front perspective view of the dual nozzle attachment200ofFIG.10. The opening205is shown as a circular opening for connection to a hair dryer with a circular barrel. Body206tapers to connect to the first nozzle210, and second nozzle220.

Referring toFIG.13, opening205is shown at the bottom of the figure and body206tapers and is connected to first and second nozzles210and220. The distal opening length201is shown as the inner width of openings270and280of nozzles210and220, respectively. In this embodiment, the distal opening length201is about 60 (mm) and preferably 60 (mm). Each nozzle210and220tapers, in reverse of the taper of body206from a greatest width at distal end openings270and280of nozzles210and220.

FIG.14shows opening205of dual nozzle attachment200at the bottom of the figure. Body206tapers to connect to nozzles210and220as shown. In this embodiment, nozzle220is the same length as nozzle210. The tips at distal end openings270and280of nozzles210and220are positioned coplanar to each other.

FIG.15illustrates the angles of the nozzles210and220. An imaginary dotted line235is shown adjacent and parallel to the distal ends270and280of nozzles210and220. Nozzles210and220each have sidewalls212and222respectively that than form right angles240with respect to distal ends270and280of nozzles210and220as also shown inFIG.14.

As shown inFIG.16, opening205is a circular opening and body206tapers to connect to both nozzles210and220. The opening of nozzle210is 270, and the opening of nozzle220is 280. Each opening270and280has a width202. In the embodiment shown inFIG.16, width202is about 3.5 (mm) and preferably 3.5 (mm).

As shown inFIG.17, openings270and280of nozzles210and220are visible from the rear view through opening205.
