Technical Field

[0001] The invention relates to hair dryer technology, and in particular to providing a high-speed hair dryer nozzle structure. Background Art

[0002] A hair dryer (commonly known as an "electric hair dryer" or "electric blower") is composed of an electric heating element located near the air outlet and a high-speed fan behind it. However, the heating element and the high-speed fan are not simply a front-to-back combination. Numerous technical considerations must be considered, including wind speed and direction, heat resistance and scalding resistance, manufacturing costs, and ease of use. Summary of the Invention

[0003] In order to solve the above technical problems, the main purpose of the present invention is to provide a high-speed hair dryer nozzle structure.

[0004] In order to achieve the above object, the technical solution applied by the present invention is:

[0005] Disclosed is a high-speed hair dryer nozzle structure, comprising a connecting base, an inner cover and an outer cover, wherein the connecting base comprises an annular base, a buckle ring extending from the annular base, and a plurality of buckle holes distributed on the buckle ring; the inner cover comprises a conical portion and a flat portion, the conical portion comprising a conical cavity, a front annular surface and a rear annular surface, and the flat portion comprises an air duct penetrating the front end surface and communicating with the conical cavity; the shell cavity of the outer cover is larger than the inner cover, so that a heat-insulating gap is formed when the inner cover is placed in the outer cover, and the outer cover comprises a rear shell on which the conical portion is sleeved and a front shell on which the flat portion is sleeved, and a wall surface of the rear shell is provided with protrusions that abut against the front annular surface and blocks that fit into the buckle holes, so that when the outer cover fits into the connecting base, the inner cover is also secured to the connecting base.

[0006] In this embodiment, it is preferred that: a magnetic ring is embedded in the annular seat on the side opposite to the snap ring; the outer diameter of the annular seat is larger than the outer diameter of the snap ring to form a step surface, and the outer diameter of the outer ring surface of the snap ring is smaller than the inner diameter of the step surface, so that a conical surface is formed on the periphery of the snap ring.

[0007] In this embodiment, preferably, the connecting seat further includes a hemispherical portion and a plurality of diverter ribs connected between the annular seat and the hemispherical portion, and diverter holes are formed between adjacent diverter ribs.

[0008] In this embodiment, preferably: a diverter plate extends from the convex surface of the hemispherical portion, forming a concave surface opposite to the convex surface; the diverter rib extends to form a rib plate, and the rib plate is connected between the buckle ring and the convex surface.

[0009] In this embodiment, preferably, slots are formed on both sides of the air duct, and the two sides of the diverter plate close to the root are respectively adapted to the corresponding slots.

[0010] In this embodiment, preferably, the high-speed hair dryer includes a metal ring for the magnetic ring to adsorb.

[0011] In this embodiment, preferably, the metal ring is a stainless iron ring, which is provided at the air outlet end of the air duct body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The use of a magnetic ring to absorb the metal ring allows the nozzle structure to be quickly and accurately configured on the main body of the hair dryer. It also allows the nozzle structure to be adjusted to any angle on the main body of the hair dryer, achieving an effect of convenient use.

[0015] 2. The nozzle structure adopts the gap insulation between the inner cover and the outer cover, which ensures the safety of use.

[0016] 3. The design of distributing the diverter plate, diverter hole and diverter plate in the flat air duct can effectively gather hot air and strengthen the wind force. At the same time, it can reduce the overheating of the air outlet by gathering the wind and avoid the safety hazards caused by overheating.

[0017] 4. Through the card block, button hole adaptation and corresponding structural support, the connecting seat, inner cover and outer shell are effectively combined together. This simple structural combination design is easy to manufacture and maintain, and effectively reduces product costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. As used herein, "one" not only means "only one" but also "more than one."

[0027] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0028] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and rear) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when the components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, the directional indications will also change accordingly.

[0029] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0031] In this embodiment, if Figures 1 to 4 The figure provides a high-speed hair dryer nozzle structure. The nozzle structure 20 is not limited to being quickly configured (referred to as "quickly installed") on the hair dryer body 10 by magnetic attraction. In this example, the nozzle structure 20 includes a connecting seat 21, an inner cover 22 and an outer shell 23, wherein:

[0032] The connecting seat 21 includes an annular seat 211, a hemispherical portion 212 and a plurality of diverter ribs 213 connected between the annular seat and the hemispherical portion, and diverter holes (or "air outlets") 214 are formed between adjacent diverter ribs. In this example, a magnetic ring 2111 is embedded on one side of the annular seat 211, and a buckle ring 2113 is extended from the other side opposite to the magnetic ring 2111. The outer periphery of the buckle ring 2113 is indented into the outer periphery 2112 of the annular seat to form a step surface (not marked). The outer diameter of the outer ring surface 2115 of the buckle ring is smaller than the inner diameter of the step surface, so that the outer periphery of the buckle ring forms a conical surface with several buckle holes 2114 distributed on the conical surface. A diverter plate 2121 extends from the convex surface of the hemispherical portion 212, forming a concave surface (also called a "hemispherical cavity") 2122 opposite to the convex surface. The diverter rib 213 extends to form a rib 2131, which is connected between the buckle ring and the convex surface to guide the wind direction.

[0033] The inner cover 22 is secured to the connecting seat 21 by the sleeved outer shell 23, and includes a conical portion 221 and a flat portion 222. The conical portion 221 has a conical cavity 2211 and a rear annular surface 2212 for abutment with the outer annular surface 2115, and a front annular surface 2213 opposite the rear annular surface. The flat portion 222 has an air duct 2221 that passes through the front end face and connects to the conical cavity, with slots 2215 formed on both sides of the air duct for the diverter plate 2121 to fit. When the inner cover 22 fits the connecting seat 21, the hemispherical portion 212 is convex to the conical cavity 2211, and ribs 2214 are formed on the hemispherical surface opposite to the conical cavity. The diverter plate 2121 is suspended in the air duct near the conical cavity, and the two sides near the root of the diverter plate are stuck in the corresponding slots 2215, so that the inner cover 22 cannot be rotated or displaced after fitting with the connecting seat 21.

[0034] The outer shell 23 fits over the inner cover 22, creating a thermal insulation gap between the two (the so-called thermal insulation gap means that the outer shell is based on the outer shape of the inner cover and there is a distance between the outer shell wall and the outer periphery of the inner cover). The outer shell 23 includes a rear shell 231 that fits over the outside of the conical portion 221 and a front shell 232 that fits over the outside of the flat portion 222. When the rear shell fits over the conical portion 221, the bottom surface of the rear shell abuts the step surface of the buckle ring 2113, and the outer surface of the rib 2214 abuts the wall surface of the rear shell (not labeled). In this example, the wall surface of the rear shell is distributed with protrusions 2311 that abut against the front annular surface 2213 and blocks 2312 that fit into the buckle hole 2114, making it easy to enter but difficult to retreat. When the outer shell 23 fits into the connecting seat 21, the protrusions abut against the front annular surface, ensuring that the inner cover 22 is firmly fixed to the connecting seat 21 and cannot fall off.

[0035] In this embodiment (see Figure 1 and Figure 2 ), the figure shows a metal ring 30 for magnetic ring 2111 to attach to. The metal ring is preferably made of stainless steel and is integrally formed with the air outlet end (not labeled) of the air duct body 10. During use, the nozzle structure 20 is attached to the air duct body 10 by magnetic ring 2111, providing convenient use. Since the stainless steel and air duct body 10 are not key design features of this embodiment, they will not be further described here.

[0036] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0037] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
