Multiple nozzle attachment for hair dryer

Abstract

A multiple nozzle attachment for a hair dryer is provided. The multiple nozzle attachment has at least two nozzles that concentrate air flow and optimize exiting air pressure while maximizing air flow volume.

Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates to nozzle attachments for hair dryers. More particularly, the present disclosure relates to nozzle attachments for hair dryers that each minimize the decrease in air pressure while increasing the air flow volume emitting from the nozzle attachment more than conventional nozzle attachments.

2. Description of Related Art

Various types of attachments are used to alter air flow characteristics of the air exiting the barrel of a hair dryer. Current nozzle attachments increase the pressure of air exiting the barrel of a hair dryer while limiting the air flow volume exiting the barrel.

SUMMARY

It is an object of the present disclosure to optimize air flow volume of a hair dryer while, at the same time, optimizing pressurized, concentrated air flow by providing a single nozzle attachment for a hair dryer that has multiple nozzle concentrating portions (hereinafter called “multiple nozzle attachment”).

The present disclosure provides for such a multiple nozzle attachment that minimizes the drop in pressure while maximizing air flow volume. In other words, the pressure of air exiting the multiple nozzle attachment is greater than the pressure of air exiting a singular nozzle attachment of equivalent, effective distal exit area.

DETAILED DESCRIPTION

Referring to the drawings and, in particular, FIG. 1, there is shown a multiple nozzle, nozzle attachment 100 of the present disclosure. As noted above, the multiple nozzle, nozzle attachment has two nozzle portions called a “dual nozzle” attachment 100 for the embodiment shown. Dual nozzle attachment 100 has an opening that is used to connect to the barrel or concentrator of a hair dryer (not shown). Opening 105 in the embodiment shown in FIG. 1, is a circular opening at the proximal or rear end of dual nozzle attachment 100. However, in other embodiments, opening 105 can 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 attachment 100 has a first or top nozzle 110, and a second or bottom nozzle 120 both placed at the front or distal end of the dual nozzle attachment as shown. Attachment 100 has a body 106 tapered from opening 105 to connect with the first and second nozzles 110 and 120. The tapering includes a tapered portion 107 and a steep taper portion 108. The body portion 106 has basically a conical shape with a wider circumference at opening 105 than the circumference at the topmost area where tapered portion 107 and steep taper portion 108 meet or where body 106 connects to nozzles 110 and 120. In this embodiment, nozzles 110 and 120 are shaped as rectangular structures having a pair of side walls 112 and 122, respectively, with curved edges 114 and 124 respectively, as shown, that together form similarly shaped distal end openings 170 and 180, respectively, at the distal ends or tips. In some embodiments each of the sidewalls 112 is parallel to each other, and each of the sidewalls 122 is parallel to each other. In some embodiments nozzles 110 and 120 are parallel to each other. In some embodiments the shape of the body 106 between each of the multiple nozzles conveys air towards the nozzles by tapering the body towards each nozzle.

In other embodiments of the present disclosure, attachment 100 can have any number of nozzles, such as three, four or five nozzles.

Once attachment 100 is connected to the barrel of a hair dryer, attachment 100 alters the air flow exiting the dryer when the dryer is in use. Specifically, the dual nozzle attachment 100 provides 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 openings 170 and 180.

Referring to FIGS. 2 and 3, opening 105 is shown as a circular opening in this embodiment, for connection to a hair dryer with a circular barrel. From opening 105, body 106 tapers to connect to the first nozzle 110 and second nozzle 120.

Referring to FIG. 4, opening 105 is shown at the bottom of the figure. As shown, body 106 tapers outward and connects to the first and second nozzles 110 and 120, respectively. The distal ends of first and second nozzles 110 and 120 have a length 101. Length 101 is shown as the inner length of the distal end openings 170 and 180 of nozzles 110 and 120. In this embodiment, length 101 is about 60 millimeters (mm) or is 60 (mm). It should be noted that length 101 is the same for first nozzle 110 and second nozzle 120, but in a less preferred embodiment of dual nozzle attachment 100, length 101 can be different for each of the two nozzles.

FIG. 5 shows, the right-side of dual nozzle attachment 100. The left-hand side (not shown) would be a mirror image of FIG. 5. In FIG. 5, opening 105 is shown at the bottom of the figure. Body 106 tapers to connect to nozzles 110 and 120 as shown. Nozzle 120 is shorter in length than nozzle 110. The distal ends or tips of nozzles 120 and 110, respectively, are angled and preferably at the same angle as discussed below.

FIG. 6 further illustrates the various angles of distal ends or tips at distal end openings 170 and 180 of nozzles 110 and 120, respectively. An imaginary dotted line 135 is shown adjacent and parallel to distal end openings 170 and 180 of nozzle 110 and 120. Another imaginary line 136 is shown adjacent and parallel to the bottom surface of opening 105, and perpendicular to the sidewalls 112 and 122. Angle 130 is formed at the intersection of lines 135 and 136. In the embodiment shown in FIG. 6, angle 130 is 30 degrees.

In FIG. 7, first nozzle 110 is shown at the front and second nozzle 120 is shown at the rear. Each nozzle 110 and 120 tapers, in reverse of the taper of body 106, from its greatest width at distal end openings 170 and 180 of nozzles 110 and 120, respectively, to the least width or lowest point 190 of body 106 that is near, but not at opening 105 as shown.

Referring to FIG. 8, each distal end opening 170 and 180 has a width 102. In the embodiment shown in FIG. 8, width 102 is about 3 millimeters (mm), preferably 3 mm.
